Description

  The present invention relates to a baby carrier (childcare band) that assists and carries an infant when holding or carrying it, and in particular, the height position (depth position) of an infant's buttocks can be adjusted. Is about a baby carrier.

  As a baby carrier that can be used for a long time without limiting the age of the infant to be held, according to the growth of the infant, by switching the user's wearing method from the horizontal holding of the infant to the vertical holding form, Although it has been known that it can be used for a long time from the neonatal period before sitting at the neck to 2 to 3 years old, recently a baby carrier corresponding to vertical holding from the neonatal period before sitting at the neck has also been proposed. ing. However, even in a specific form of holding in a vertical manner, the holding state of a stable and comfortable holding comfort with little burden on the infant changes according to the age, size, and growth of the infant. In addition, there are individual differences in individual body shapes of infants, and the optimum holding position with less burden on users such as infants and parents who hold infants differs depending on how to hold them. In particular, in infants before sitting on their necks, the ligaments that connect the muscles and joints are undeveloped and the joints of the crotch and knees are soft.

  Here, in Patent Document 1 and Patent Document 2, a backrest part, a crotch pad part, and a front pad part are configured to be continuous, the crotch pad part is bent and formed in a side U shape, By connecting the both sides and both side surfaces of the front padding portion using a desired cloth or the like, a lullaby body formed in a bag shape or a cylindrical shape is constructed, and a predetermined length is provided from both sides of the upper end portion of the lullaby body. Now, the shoulder strap is stretched, and the tip portion thereof is configured to be locked at an appropriate portion of the waistband formed at the lower end portion of the lullaby body. A baby carrier constructed so that both ends of an auxiliary band for seat height adjustment are attached so as to pass between the inner side and the inner side of the front contact part, and at least one end part of the auxiliary band can be detachably locked by a locking tool. Is disclosed. As described in Patent Document 1 and Patent Document 2, according to such a baby carrier, a comfortable sitting height and a feeling of use that are the same as those of an infant with a standard body shape can be obtained even with an infant whose main body is smaller than the standard body shape that is planned. Is going to be able to get

  Further, Patent Document 3 discloses that a back portion, a crotch portion, a front portion and the like are made continuous, and both sides of the back portion and both sides of the front portion are connected to form a cylinder (bag shape). The size of the crotch part (size formed by the crotch part) can be freely changed by interposing a seat height adjustment belt between the crotch part and the front part in the formed baby limp body. Thus, a lullaby that can freely adjust the sitting height is disclosed.

  Furthermore, in the baby carrier disclosed in Patent Document 4, the size and length of the seating portion are adjusted by providing an elongated tongue piece on the seating portion of the infant through the lower coupling device and changing the length of the tongue piece. The baby carrier size can be adjusted according to the height of the child.

However, in the baby carriers described in Patent Document 1 and Patent Document 2, at least one end of the auxiliary seat for seat height adjustment attached so as to pass inside the back rest and the crotch rest is at the back rest, the crotch rest. The auxiliary belt and the main body are connected to each other because it is configured so that it can be detachably locked with a velvet fastener, a metal fitting, a belt, or the like with respect to the main body formed continuously with the front portion and the front portion. There was a concern about durability due to the load being easily applied to the locking portion. In particular, it is difficult to obtain a high connection strength at the connecting portion between the auxiliary belt and the main body portion with the velvet type fasteners described in Patent Literature 1 and Patent Literature 2 or the fasteners using metal fittings and belts. As a result of vibration caused by walking, the auxiliary belt rocks and the posture of the infant seated on the auxiliary belt tends to become unstable. Furthermore, even if the locking tool for making the auxiliary belt detachable is covered with the lid piece, there is a risk of giving the infant an uncomfortable feeling such as unevenness or discomfort.
In Patent Document 1 and Patent Document 2, there is no pursuit for an infant's open leg posture, and the technical idea of maintaining an open leg posture that does not impose a burden according to the age, size, and growth of the infant. There is no disclosure or suggestion.

  In addition, the techniques described in Patent Document 3 and Patent Document 4 enable adjustment of the length of the main body part itself that constitutes the backrest part, the crotch part, the front part, and the like. The area (size) of the part applied to the infant's body is changed by the adjustment. Therefore, the design freedom of the main body is restricted, for example, when trying to set the width size so that it can be held in an open leg posture that does not place a burden on infants at a low age, when the infant becomes large, The area (size) necessary to sufficiently cover the enlarged infant's buttocks cannot be secured, the burden on the infant is increased, and a stable holding state cannot be obtained.

  Therefore, it is possible to adjust the holding position of the infant and to maintain an open leg posture that does not impose a burden according to the age, size, and growth of the infant. An object of the present invention is to provide a baby carrier that enables a small and stable holding.

  The baby carrier of the invention of claim 1 is attached to the user by a pair of left and right shoulder belt portions, and is applied to the infant's body to support the infant in a wide area, and one end is the lower end of the body portion. An auxiliary holding portion that is connected to the body and is applied to the infant's body on the opposite side of the main body portion, and the main body portion and the auxiliary holding portion are integrally and continuously between the main body portion and the auxiliary support portion. And a positioning pedestal for positioning the sinking depth of the buttocks of the infant.

  The main body is applied to the infant's back when holding the infant so that the abdomen of the infant's body faces a parent or other user holding the infant, such as a face-to-face hug or a forward-facing piggyback. And the head and neck as appropriate to support and protect the infant's body over a wide area.

The auxiliary holding portion is disposed closer to the user holding the infant than the main body portion and is connected to the lower end portion of the main body portion, and a free end thereof extends upward, and the main body portion is applied. It is applied to the infant's body on the opposite side of the face. In other words, when holding an infant so that the infant's body's ventral side faces a parent or other user holding the infant, such as a face-to-face hug or a forward-facing piggyback, it is applied to the infant's body's ventral side (reverse side). Is. Usually, it is applied to the infant's body's ventral side (anti-dorsal side) with a smaller area than the main body, and one end connected to the lower end of the main body is in the left-right direction (horizontal direction) of the lower end of the main body. The width is narrower than the width.
The main body part and the auxiliary holding part are arranged such that the auxiliary holding part is arranged closer to the user side and the main body part is arranged farther from the user side.

  The shoulder belt portion is hung on the user's shoulders when holding or carrying an infant, and the main body portion and / or the auxiliary member is provided at a distance sufficient to turn the shoulder and back of the user. It is connected to the left and right sides of the holding part.

The positioning pedestal portion is integrally and continuously passed from the main body portion and the auxiliary holding portion between the main body portion and the auxiliary holding portion on the opposite sides of the main body portion and the auxiliary holding portion. The length can be freely adjusted by folding in the direction, and the sinking depth of the buttocks of the infant is positioned by adjusting the length.
Here, the length adjustment is performed by fixing the folded state by engaging engagement means formed integrally with the positioning pedestal, for example, fasteners, snaps, buttons and loops, hooks and rings, and adhesive cloths. The length of the pedestal part can be shortened and the length of the positioning pedestal part can be adjusted in a form in which the fold is unfolded by releasing the engagement, or the folded state can be fixed by attaching a separate adjuster The length may be shortened and the length may be adjusted in a form in which the fold is unfolded by removing an adjuster or the like.

  Preferably, the positioning pedestal is connected to the auxiliary support portion in accordance with a sinking lateral width of the buttocks of the infant when the length between the main body portion and the auxiliary holding portion is shortened by folding in the length direction. The width of the lower end of the main body is 5/10 to 9/10, more preferably 3/5 to 4/5.

Here, the sinking lateral width of the buttocks of the infant when the length between the main body portion and the auxiliary holding portion is shortened passes between the main body portion and the auxiliary holding portion by folding in the length direction. In the positioning pedestal portion whose length is shortened, it means the width of the lowermost part where the infant's buttocks are landed, that is, the position where the infant's buttocks is positioned by receiving the sink of the infant's buttocks.
And, when the length between the main body part and the auxiliary holding part is shortened, the sinking lateral width of the buttocks of the infant is within the range of 5/10 to 9/10 of the lateral width of the lower end part of the main body part. Preferably, the range of 3/5 to 4/5 is set so as not to apply a load to the infant's body shape, particularly the soft hip joint, even if the target is a younger infant before the neck It is. In addition, the lower end part of the said main-body part is a connection location with the lower end part of the said auxiliary | assistant holding | maintenance part.

By reducing the length between the main body portion and the auxiliary holding portion in the positioning pedestal portion, the depth between the main body portion and the auxiliary holding portion is reduced to both the main body portion and the auxiliary holding portion. The baby's buttocks are received by the positioning pedestal with a shorter length between the main body part and the auxiliary holding part at this time, from the closed bottom end to which is connected. If the width of the sinking is a width that is the same as the lower end of the main body that is set to a reasonably wide dimension that can cover the buttocks surface even for a large infant that has grown up, If the infant is a younger infant, the leg of the infant B cannot be lowered below the positioning base unless the crotch width is greatly increased. That is, infants are required to open a large crotch width.
Therefore, the lateral width of the positioning part that is received by the positioning pedestal portion when the length between the main body portion and the auxiliary holding portion is shortened and is reached by the infant's buttocks is determined by the lower end portion of the main body portion. The width is 5/10 to 9/10, more preferably 3/5 to 4/5. The leg posture is not overwhelmed.

Here, when the length between the main body portion of the positioning pedestal portion and the auxiliary holding portion is shortened, the sinking lateral width of the buttocks of the infant is less than 5/10 of the lateral width of the lower end portion of the main body portion. , The hips and buttocks of the infant may be compressed. On the other hand, when the width of the lower end of the main body exceeds 9/10, the crotch width is excessive for younger infants before sitting on the neck. May be demanding, and will impose a burden on young infants who are underdeveloped.
When the length between the main body part of the positioning base part and the auxiliary holding part is shortened, the sinking lateral width of the buttocks of the infant is 5/10 to 9/10 of the lateral width of the lower end part of the main body part. Within the range, more preferably within the range of 3/5 to 4/5, even if the infant of low age before sitting in the neck is intended to be held, the positioning pedestal sunk the infant's buttocks Infants too widen the crotch width from the lower position of the positioning pedestal to the closed lower end where both the auxiliary holding part and the main body are connected by the depth being raised to the upper part. The leg can be accommodated without any problems, and the hip joint and the buttocks are not compressed, and the infant's leg posture is reduced.

  Preferably, the auxiliary holding portion has a lateral width between the main body portion and the auxiliary holding portion at the maximum from the connection position with the lower end portion of the main body portion to a height position of 15 cm. It is set to 1.4 times or less of the sinking lateral width of the buttocks of the infant when the length is shortened.

  From the connecting position of the auxiliary holding part to the lower end part of the main body part to the height position (length position) of 15 cm is the positioning when the length between the main body part and the auxiliary holding part is shortened. The lower part from the knees of both legs of the infant whose buttock is received by the pedestal part is a part that is extended from the left and right sides of the auxiliary holding part. Usually, assuming the body shape of a young infant before sitting on the neck, the length between the main body part of the positioning pedestal part and the auxiliary holding part is shortened to increase the sinking depth of the infant's buttocks upward (high position) In the case of setting to), even if considering the deflection due to the weight of the infant and the like, it is about 5 cm to 10 cm at the maximum from the lower end of the main body part connected to the auxiliary support part. In the posture, the lower part is lower than the knees of both legs of an infant with a low age that opens in an M shape that is held at a high position in the range from the connection position with the lower end of the main body part to a height position of 15 cm. Will be served from both sides.

  Here, when the buttocks of the infant are held at a high position, the lateral widths of the left and right sides of the auxiliary holding part that are lower than the knees of both legs of the infant are the length between the main body part and the auxiliary holding part. When the width of the lower part of the infant's buttocks exceeds 1.4 times the width when the length is shortened, the infant's buttocks are positioned at a positioning portion for receiving the infant's buttocks with the width of the lower end of the main body being a predetermined narrow width. When this is done, the movement of the leg of the infant is liable to be restrained due to the wide dimensions of the auxiliary holding part, and the freedom of movement of the leg is lost. Further, because of the cramped feeling and inconvenience, the infant may excessively widen the crotch width trying to get out the legs from both sides of the auxiliary holding part. In particular, when the movement of the leg of the infant is restricted, the burden on the infant with a young age who is not yet well-developed is large, and the motor function of the infant may be hindered.

Therefore, in the auxiliary holding portion, the lateral width on both the left and right sides from the connection position with the lower end portion of the main body portion to the height position of 15 cm is set to the maximum length between the main body portion and the auxiliary holding portion. By setting it to 1.4 times or less the sinking width of the buttocks of the infant when shortened, the infant's leg movement is not limited even when targeting a younger infant before sitting down the neck. It is possible to prevent the crotch width from becoming too wide. Therefore, there is no fear of inhibiting the infant's motor function, and the load on the infant's body shape can be reduced.
To the height position of 15 cm, it is necessary to set a predetermined lateral width at a height of at least 15 cm, but the range of the predetermined lateral width dimension may be 15 cm or more.

  In the baby carrier according to the second aspect of the present invention, when the positioning pedestal portion is folded in the length direction to shorten the length between the main body portion and the auxiliary holding portion, the folded portion is the sinking of the infant's buttocks It becomes the positioning part which receives. Preferably, the folded portion is selectively set as a positioning portion, and the thickness of the positioning portion that receives the sinking of the buttocks of the infant can be selected.

  According to a third aspect of the present invention, the baby carrier according to the third aspect of the present invention is configured so that the right and left sides of the body carrier can be bent toward the infant side (inward). The space to be accommodated has a depth.

According to a fourth aspect of the present invention, the baby carrier further includes a waist belt portion that is connected to the lower end portion of the main body portion and the auxiliary holding portion and is worn around the waist of the user.
The waist belt part is attached to a user's waist when holding or carrying a baby, positioning the main body part that supports the baby, and supporting the weight of the baby. It is arranged so as to draw a substantially inverted T shape with respect to the main body part and the auxiliary holding part, and is attached around the waist of the user by a connecting tool such as a buckle disposed at the end in the horizontal length direction. , Removable. The connection of the waist belt part to the main body part and the auxiliary support part may be sewing, or may be a structure that can be attached and detached by an engaging means or the like.
The up, down, left, and right directions described above indicate the directionality in a vertical holding state in which an infant is held or carried.

  According to the baby carrier of the first aspect of the present invention, the main body portion is disposed between the main body portion applied to the infant body and the auxiliary holding portion applied to the infant body on the opposite side of the main body portion. And a positioning pedestal portion formed integrally and continuously from the auxiliary holding portion is disposed and arranged, and the positioning pedestal portion is adjusted in a length direction so that the auxiliary holding portion of the main body portion is adjusted. It is possible to freely adjust the depth between the two, and the sinking depth of the buttocks of the infant is positioned. Therefore, the positioning base part disposed between the main body part and the auxiliary holding part receives the buttocks of the infant accommodated between the main body part and the auxiliary holding part, but the main body is folded by folding the positioning base part. If the length that passes between the main part and the auxiliary holding part is shortened, the sinking depth of the infant accommodated between the main part and the auxiliary holding part increases, and the folding of the positioning pedestal part is unfolded to expand the main part and the auxiliary holding part. If the length passing between the parts is increased, the sinking depth of the infant accommodated between the main body part and the auxiliary holding part is lowered, and the adjustment of the length passing between the main body part and the auxiliary holding part by the positioning pedestal part is performed. The height position of the infant to be held can be adjusted.

Therefore, even for young infants with small bodies, the length passing between the main body part of the positioning base part and the auxiliary holding part is shortened by folding in the length direction, so that the lower end part of the main body part and the lower end part of the auxiliary holding part Since the infant can be held at a position higher than the connection position, the infant's head position protects the infant without sinking or being buried between the main body and the auxiliary holder. Arranged at an appropriate position of the main body, the burden on the infant can be reduced and comfortable holding is possible. Also, when the infant grows up and the body grows large, the folding is unfolded, the length passing between the main body part of the positioning base part and the auxiliary holding part is lengthened, and the lower end part of the main body part and the auxiliary holding part are held. The infant is held at a low position on the connection side of the lower end of the part, and the infant's body is protected at an appropriate position on the main body part to enable comfortable holding. And the height position of the infant can be adjusted to a comfortable holding position for the user.
According to the age, size, and growth of the infant to be held in this way, the holding height position of the infant is adjusted to enable holding with less burden on the infant and the user.

  In addition, since the positioning pedestal portion raises the sinking depth of the buttocks of the infant to the upper level, the opening width of the crotch width of the infant is not affected by the width of the lower end portion of the main body portion, and the positioning pedestal Since the infant can fit the leg into the space from the lower part of the part to the closed lower end where both the auxiliary holding part and the main body part are connected, the hip joint is opened for younger infants. It is possible to prevent overshoot.

  And since the positioning pedestal for positioning the depth of the buttocks of the infant is formed integrally and continuously from the main body and the auxiliary holding part, the connection strength is stable without any positional deviation. In addition, the positioning pedestal portion is not detached from the main body portion and the auxiliary holding portion due to the weight of the infant, and the reliability is high. In addition, even when the infant's buttocks are received by the positioning pedestal when the length between the main body part and the auxiliary holding part is shortened, the swinging is small and the center of gravity of the infant's buttocks is easy to stabilize, and the posture is stable. It can reduce the burden on infants who are not stable and have a low age before sitting.

  In this way, it is possible to adjust the holding position of the infant and to maintain an open leg posture that does not impose a burden according to the age, size, and growth of the infant. Infants and children can be held stably with little burden.

In particular, in the positioning pedestal portion, when the length between the main body portion and the auxiliary holding portion is shortened, the sinking lateral width of the buttocks of the infant is 5 / 10-9 of the lateral width of the lower end portion of the main body portion. / 10, more preferably, by forming a narrow width within the range of 3/5 to 4/5, the infant's crotch width is more than necessary even for younger infants before sitting in the neck. It is possible to hold the leg with a natural leg posture with an M-shaped leg without opening the hip joint excessively. And since the lower end portion of the main body portion is wider than the sinking horizontal width of the buttocks of the infant when the length between the main body portion and the auxiliary holding portion is shortened, the positioning base portion is folded and the main body is expanded. Even when the infant's buttocks are received by the positioning pedestal that extends between the head and the auxiliary holding part, the infant's buttocks are widely covered by the appropriate wide dimensions at the bottom of the main body so that the legs are in an open leg position. Stable holding is possible without imposing a burden.
In addition, the auxiliary holding part has a width between the main body part and the auxiliary holding part at the maximum from the connection position with the lower end part of the main body part to the height position of 15 cm. When the length is shorter than 1.4 times the sinking lateral width of the buttocks of the infant, it is possible to hold the leg in an open leg posture with less burden without restraining the movement of the leg.

  According to the baby carrier of the second aspect of the present invention, when the positioning pedestal portion is folded in the length direction, the folded portion is used as a positioning portion that receives the sinking of the buttocks of the infant. In addition to the effects described, the bulkiness of the folded part increases the sense of stability. Moreover, the selection depth of the folding position of the infant can be adjusted by selecting the folding, and the selection range of the position of the holding height of the infant can be widened.

  According to the baby carrier of the third aspect of the present invention, there is a space in which the infant is accommodated by a shape in which the left and right sides of the portion of the main body portion applied to the buttocks of the infant can be bent toward the infant side. Since a three-dimensional space with a depth can be formed, it is difficult to restrain the movement of an infant at a low age especially in an M shape. Therefore, in addition to the effect described in claim 1 or claim 2, it is possible to hold less burden for infants at a low age.

  According to the baby carrier according to the invention of claim 4, further comprising a waist belt portion connected to the lower end portion of the main body portion and the auxiliary holding portion and attached to the waist of the user. In addition to the effect described in any one of claims 1 to 3, a user whose shoulders tend to be stiff due to the weight of the infant being dispersed on the shoulders, back and waist even when the infant grows up and becomes heavy. But it can reduce the load on the shoulder.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Note that, in the embodiments, the same symbols and the same reference numerals are functional portions common to those embodiments, and thus detailed description thereof is omitted here.

  The baby carrier 1 according to the present embodiment includes a main body 10 that is applied to the body of the infant B on the side opposite to the user M holding the infant B, a lower body of the main body 10, and the main body 10 side. The auxiliary holding part 20 applied to the body of the infant B on the opposite side, one end in the length direction is connected to the infant B side (inner surface side) of the main body part 10, and the other end is the infant B side of the auxiliary holding part 20 The positioning pedestal 30 connected to (inner side) and passed between the main body 10 and the auxiliary holding part 20 and the auxiliary holding part 20 is passed in the vertical direction and hung on the shoulder of the user M. A pair of left and right shoulder belt portions 40, connected to the lower portions of the main body portion 10 and the auxiliary holding portion 20, are arranged in a direction perpendicular to the length direction of the main body portion 10 and the auxiliary holding portion 20, and And a waist belt portion 50 attached around the waist.

The main body 10 applied to the body of the infant B on the opposite side of the user M holding the infant B holds the infant B on the ventral side of the body of the infant B like a face-to-face holding or a forward facing piggyback. It is applied to the back side of the body of the infant B when the infant B is held so as to face the user M such as a parent.
The main body portion 10 of the present embodiment is a substantially semi-elliptical head support portion 11 that is mainly applied to the head of the baby B and receives the head mainly when the baby B is held with a face-to-face hug or a forward-facing piggyback. And a back support part 12 which is applied from the head side of the infant B to the back and waist and mainly receives the back part, and a support part 13 which is applied from the back side of the infant B to the buttocks and mainly receives the buttocks part. Are integrally formed. The main body 10 is provided with a predetermined softness by disposing a cushion material (elastic material) or a known core material having flexibility and some elasticity between exterior fabrics made of a front fabric and a back fabric. Property, flexibility, elasticity, buffering property and the like.

As for the exterior fabric of the main body 10, for example, by using a fabric having air permeability for at least a part or all of the surface applied to the body of the infant B, the air permeability of one surface side of the infant B body is improved. In addition, stuffiness can be prevented.
Examples of the fabric having air permeability include, for example, a mesh (net) fabric having a mesh / net pattern structure with a predetermined opening, a coarse fabric with a slightly rough texture, and a mesh fabric between the front and back surfaces. A three-dimensional knitted fabric (double raschel) having a specific thickness obtained by weaving connecting yarns forming an air layer having a specific thickness is used. By using such a fabric having air permeability, air permeability can be secured and moisture and heat can be dissipated. Furthermore, by providing the fabric with a mesh structure or providing a plurality of ventilation holes in the fabric, flexibility and stretchability are increased, and the fit and familiarity with the body shape and movement of the infant B and the user M are improved. Hygroscopicity can also be improved by using a material such as a cotton material with high water absorption for the exterior fabric.

  In particular, according to the three-dimensional knitted fabric (double raschel), the air layer formed by the connecting yarn woven between the front and back mesh fabrics also accommodates moisture such as sweat of infants B and users M. In addition, since the movement of the user M and the movement of the infant B become the volume change of the air layer, the air in the air layer is discharged and supplied. It can quickly absorb the sweat perspired from and can effectively release moisture and heat. Of course, because the mesh fabric and air layer on the front and back sides are excellent in air permeability and water permeability, moisture can be dried quickly. Furthermore, the air layer formed by the connecting yarns has some elasticity, cushioning properties, etc., and even if the infant B moves, the following change in the air layer does not cause a sense of incongruity, and the infant B's body shape is also good. . In addition, since the convection is not generated in the air layer by the connecting yarn woven between the mesh fabrics on the front and back sides, the heat insulating effect is high and the volume is large, so that the heat insulating action can be maintained for a long time.

  This three-dimensional knitted fabric (double raschel) is manufactured by a woven fabric manufacturing machine such as a double raschel machine or tricot machine. The product is "Fusion (trade name)" by Asahi Kasei Co., Ltd. and "Air Queen (trademark)" by Teijin Kosan Co., Ltd. Name) ”etc., and detailed explanation is omitted here.

It is to be noted that such a breathable fabric can reduce dampness and the like by being used at least in a position corresponding to the body of the infant B, but is applied to both surfaces of the main body 10, that is, the body of the infant B. By using a fabric having air permeability on both the front surface and the opposite surface, air permeability in the thickness direction is increased, and moisture and heat can be released more effectively. Moreover, it is good also as a structure which can adjust ventilation | gas_flowing quantity by the 2 layer structure which made the cloth | batter which has air permeability freely coatable with the cloth | airs without air permeability.
Of course, when carrying out the present invention, a non-breathable fabric may be used for the entire exterior fabric.

As a cushioning material put between the outer fabric made of the front fabric and the back fabric of the main body 10, for example, commercially available urethane, the trade name “Breath Air (registered trademark)” from Toyobo Co., Ltd., and “C” from Sea Engineering Co., Ltd. -CORE ", a three-dimensional network structure and the like sold under the trade name" Airweave (registered trademark) "by Airweve, Inc. are used.
In particular, a continuous linear body made of resin is irregularly meandering and intertwined, and is adhered to everywhere in a meandering state, and a space between the continuous linear bodies is continuously formed with a predetermined thickness. According to the net-like structure, it is lighter and more breathable than urethane, and can be less sanitary and hygienic. Further, according to the three-dimensional network structure 100 in which the continuous filaments are entangled three-dimensionally and have continuous voids in this way, the pressure receiving area is widened and the pressure applied to the infant B is easily dispersed. The burden on the body can be reduced.
Furthermore, hard urethane or a three-dimensional network structure can be used as the core material.

When such a cushioning material and a core material are provided in the main body 10, the shock to the infant B's body is alleviated even when holding the infant B who is young, especially before the neck sitting, whose posture is unstable. It is possible to obtain a high holding stability with little burden on the infant B and comfortable to hold.
In addition, use of a cushion material and a core material may be used only for a specific part, and it is also possible to use it without distinguishing both a cushion material and a core material. For example, the head support part 11 and the back support part 12 have a cushioning property and are formed of a hard material, so that the head, back, and waist of the infant B can be firmly supported, and the body can be glazed. And prevent backward tilting and warping. By forming the buttocks 13 with a cushioning and soft material, the buttocks of the infant B can be easily lowered, the center of gravity of the infant B can be stabilized, and the holding stability can be enhanced. Such a cushioning material or core material may be attached and detached.

  In the present embodiment, the cushion material and the core material placed between the outer fabric and the outer fabric of the front fabric and the back fabric are not made continuous at the boundary between the head support portion 11 and the back support portion 12, or the cushion material or Even if the core material is continuous, the front and back fabrics are sewn, or the cushion material and the core material are formed so as to be foldable. The head rest part 11 can be bent with respect to the surface of the back rest part 12. Thereby, although the back part 12 supports the back part of the infant B from the waist stably, the head part 11 is easily inclined with respect to the surface of the back part 12 according to the weight of the head of the infant B. (It is easy to bend) and the head and neck of the infant B can be protected so as not to overload the head and neck of the infant B. Furthermore, according to the growth and holding form of the infant B, the field of the infant B is widened by using the head support part 11 by bending it to the opposite side of the infant B side with respect to the surface of the back support part 12. Can do.

  Moreover, in the baby carrier 1 of the present embodiment, a substantially triangular shape formed of a cushioning material on the side (inner surface side) where the infant B at the boundary between the head support part 11 and the back support part 12 is disposed. The connecting portion 14 protrudes from the surfaces of the head rest portion 11 and the back rest portion 12, and the connecting portion 14 supports the tilt of the head of the infant B in the left-right direction, prevents glare and prevents the infant B from moving. The burden on the head and neck can be reduced. In particular, the head and neck of the infant B can be protected also by the cushioning property of the connecting portion 14. Furthermore, for a younger infant B who is held at a high position and the head support 11 and the back support 12 are applied to appropriate positions, the connecting portion 14 is disposed above the torso of the infant B, It has the effect of blocking light and sound, and can also be expected to promote comfortable sleep.

  The head support 11 is provided with a pocket-shaped storage portion having a predetermined storage volume (not shown), and is a surface on the opposite side of the main body 10 shown in FIG. A slide fastener 15 (a hook, a button, an adhesive cloth, etc.) for opening and closing a storage portion (not shown) on the design surface side when the user M is wearing the baby carrier 1 may be used. ), And can accommodate a head hood (not shown) having a predetermined area covering the head of the infant M, items such as a cooling agent and a towel. For example, the head hood (not shown) has one end fixed to the storage portion by sewing or the like, and the other end connected to the shoulder belt portion 40 (for example, a buckle, hook, eggplant, carabiner, D lock, quick catch, The head of the infant B is covered and supported from the back of the head, and the head of the infant B falls backwards even when the infant B is sleeping. It functions as a cover that hides breastfeeding when the baby B is fed while being held while the baby carrier 1 is worn, or the like is prevented.

  And, by providing such a storage unit (not shown), when the head hood is not used, it can be folded and rolled in and inserted through the opening of the storage unit, and it can be stored inside, making the whole compact and designable In addition, the safety of the infant B can be improved, and the presence of the head hood and the like can be obscure by closing the opening of the storage portion with the fastener 15 or the like, and the belongings stored in the storage portion fall. There is nothing. However, when the present invention is implemented, the head hood may be wound and fixed with an adhesive cloth or the like without being provided with a storage portion, and may be configured to be held in an orderly manner, or the storage portion and the head hood may not be provided. .

  Further, in the abutment portion 13 of the present embodiment, a center portion 13A that receives the center side of the buttocks of the infant B and a pair of left and right end portions 13B that are located on both the left and right sides of the center portion 13A and that are near the thighs of the infant B It is composed of

In the baby carrier 1 according to the present embodiment, the center portion 13A and the pair of end portions 13B of the holding portion 13 are formed by draping, and the center portion 13A and the pair of end portions 13B are formed on the inner side ( A pair of sewing lines 13a curved in an arc shape toward the center side) are joined to each other, and an end portion 13B is formed to be foldable toward the infant B side with respect to the surface of the central portion 13A. Further, the lower end portion of the abutment portion 13 is curved in a substantially arcuate manner with a substantially straight sewing line 13b that contacts the upper end portion of the main body belt portion 51 with respect to a main body belt portion 51 of the waist belt portion 50 described later. They are integrally connected by a sewing line 13c (see FIGS. 6 and 8).
Thus, the formation of the three-dimensional accommodation space makes it difficult for the movement of the leg of the infant B when held at a high position, which will be described later, to be restrained, and also the position of the center of gravity of the buttocks of the infant B is easily stabilized.

  In other words, the end portions 13B on the left and right sides of the abutment portion 13 are brought closer to the infant side by draping, and the connection of the abutment portion 13 to the waist belt 50 is performed on the two sides of the sewing line 13b and the sewing line 13c. Therefore, since the depth is increased and the accommodation space can be afforded, the movement of the leg of the infant B can be played. Furthermore, the center of gravity of the buttocks of the infant B is easy to stabilize. Particularly, the outer shape of the central portion 13A joined to the end portion 13B by the sewing line 13a is a shape curved toward the central side, that is, a shape narrower on the central side than the upper and lower end portions. Is easy to drop, and the position shift of the buttocks hardly occurs. Therefore, the child B can be held in a comfortable posture with less burden, and the holding stability is increased. That is, the position of the center of gravity is determined from the position of the buttocks of the infant B, and there is no difficulty in holding the infant B.

  In addition, the center portion 13A and the end portion 13B in the holding portion 13 can be connected by preventing the cushion material or the like placed between the outer fabric and the outer fabric of the front fabric and the back fabric from being continued, or even if the cushion material or the like is continued. By sewing the front fabric and the back fabric, or by forming the cushion material itself so as to be foldable, the center portion 13A and the end portion 13B are distinguished from each other, and the end portion with respect to the surface of the center portion 13A. 13B is formed in the infant B side so that bending is possible.

  In the case of carrying out the present invention, in the central portion of the heeling portion 13, it is formed by draping, or by changing the thickness of the cushioning material to be put into the outer fabric of the front fabric and the back fabric, etc. Infant B can also be formed by forming a recess so that the buttocks can fall freely, or by changing the cushioning properties and flexibility of the cushioning material placed in the outer fabric of the front fabric and the back fabric. It is possible to stabilize the drop of the buttocks and improve the holding stability.

  In addition, for the infant B held in an open leg state, the thighs are easily loaded by the outer edges of the right and left sides of the butting part 13 being in contact with each other. In the end portion 13B, the cushioning property of the infant B can be reduced by increasing the cushioning property compared to the central portion A by disposing a cushioning material having a high cushioning property.

Furthermore, in the baby carrier 1 of the present embodiment, the lateral width on the upper side of the abutment portion 13 is gradually narrowed toward the backrest portion 12 side. That is, on the upper side of the abutment portion 13, the outer edges of the left and right end portions B are inclined inward (center side) upward.
Thereby, even when holding the buttocks of the infant B at a low position as will be described later, the lower part of the buttocks 13 receives the buttocks by a wide dimension that covers the buttocks of the infant B and stably supports the depression of the buttocks. However, the movement of the leg of the infant B becomes difficult to be restrained by being narrow toward the top. Therefore, holding in a comfortable open leg posture is possible.

  In addition, although the butting part 13 of this Embodiment is formed in the area of the area which surrounds the buttocks of the infant B in the state of an open leg, the horizontal width of the lower end part is usually set in the range of 20 cm to 35 cm. More preferably, it is within the range of 23 cm to 30 cm, so that the width of the crotch of the infant B is unnecessarily widened to limit the movement of the leg corresponding to the body shape of the infant B in Japan (Japan). The burden on the body shape of the infant B in the leg state can be minimized. The width dimension here is a numerical value obtained by measuring the fabric length between the left and right edges on the outer surface side of the abutment portion 13 formed by draping.

  Moreover, in the baby carrier 1 of the present embodiment, the horizontal width in the horizontal direction is narrow at the boundary between the backrest portion 12 and the abutment portion 13 and the design is such that the abutment portion 13 widens downward from there. In particular, the buttocks 13 make it easy for the baby B to drop the buttocks. Moreover, in the back support part 12 and the back support part 13, by changing the characteristics such as cushioning and hardness, for example, by making the hardness of the back support part 13 soft compared to the back support part 12, The buttocks 13 of the infant B can be easily depressed in the hitting unit 13.

  For example, the vertical length of the backrest 12 and the heel rest 13 combined with each other corresponds to, for example, the length of the upper body of the average infant B from 4 to 12 months after sitting on the neck. 40 cm to 45 cm, and the width of the lateral width of the backrest 12 is 40 cm to 4 mm, for example, corresponding to the average back width of the infant B from 4 to 12 months after sitting on the neck. Set to 45 cm.

  And in the baby carrier 1 of this Embodiment, the main body part 10 in which the head support part 11, the back support part 12, and the support part 13 are integrally formed in this way is the lower end part on the side of the support part 13. The waist belt portion 50 is sewn by the above-described linear sewing line 13b and the arc-shaped sewing line 13c. The main body portion 10 and the waist belt portion 50 are disposed in a substantially inverted T shape as a whole, and are integrally connected to the waist belt portion 50 by sewing only the lower end of the main body portion 10 and the vicinity thereof. The main body 10 can be bent in a direction perpendicular to the surface direction of 50.

  The waist belt portion 50 is disposed in a direction substantially orthogonal to the length direction (vertical direction) of the main body portion 10 and the auxiliary holding portion 20 below the main body portion 10 and the auxiliary holding portion 20 described later. As a form in which the weight (the weight of the infant B) is distributed so that it can withstand the strength because it receives a lot of body weight, and it does not overload the body shape of the user M even if it is attached to the waist of the user M And a main body belt portion 51 that is integrated with the main body portion 10 and an auxiliary holding portion 20 that will be described later, and a fabric belt that has a wide belt and has a buckle with an adjuster disposed at both ends in the longitudinal direction of the main body belt portion 51. It comprises a pair of left and right length adjusters 52. The waist belt portion 50 can be fixed around the waist of the user M by the coupling engagement of the coupling insert 53 of the buckle with adjuster provided in the length adjusting unit 52 and the coupling receiver 54, and the coupling insertion By making the tool 53 and the connection receiver 54 connectable, the user 53 can freely attach and detach the waist of the user M.

  The main body belt portion 51 having a wide vertical width is made of a material having predetermined flexibility, flexibility, elasticity, buffering property, etc., and improves the familiarity of the user M around the waist and improves the fit. This reduces the burden on the user M. For example, the core material and the cushion material as described above are inserted between the outer fabric and the outer fabric of the front fabric and the back fabric. Thereby, the load applied to the waist of the user M is easily dispersed. In addition, in the main body belt portion 51, by using a fabric having air permeability as the exterior fabric, moisture such as stuffiness can be prevented and uncomfortable feeling can be reduced. Moreover, hygroscopicity improves also by forming the inner surface side which touches the user's M waist circumference with a cotton fabric etc. with water absorption.

  1 and 2, the overall shape of the main body belt portion 51 is such that the lower portion thereof is curved in an arc shape downward, and the vertical direction in the vertical direction is formed at the center side connected to the main body portion 10 and the auxiliary holding portion 20. The width is maximum, and the vertical width is gradually narrowed toward both ends in the length direction. The vertical width is in the range of 10 to 20 cm, and the force applied to the waist of the user M is effective. In this structure, the weight felt by the user M can be reduced.

  The pair of left and right length adjusting portions 52 provided at both ends of the main body belt portion 51 have a predetermined length so that the belt length necessary for the user M to be attached to the waist is determined. By having the adjuster function in the connection plug 53 and the connection receiver 54 made of male and female buckles with adjusters, it is possible to match the circumference of the waist of the user M. The adjuster may be an independent adjuster as long as the belt length can be adjusted, or may be an integrated adjuster.

In the present embodiment, the connecting plug 53 and the connecting receiver 54 for connecting the waist belt portion 50 in an annular shape and fixing it around the waist of the user M are constituted by a pair of male and female buckles. It is possible to attach and detach with one touch, the detaching operation is easy, and it is not detached unless it is manually disengaged, and the attachment is highly reliable and the mechanical strength is also high.
However, when implementing this invention, it is not limited to a buckle, and connecting tools, such as an eggplant, a carabiner, a spring hook, D lock, a quick catch, an elliptical ring, can be used, and any may be selected. Usually, those that can be easily connected and have high safety are used.

Furthermore, the auxiliary holding part 20 is sewn to the waist belt part 50 with the sewing line 13b with the main-body part 10. FIG.
The auxiliary holding portion 20 is disposed on the infant B side of the main body portion 10, and the lower end portion thereof is integrally attached to the waist belt portion 50 together with the main body portion 10. Otherwise, the auxiliary holding portion 20 is separable from the main body portion 10. It is applied to the body of the infant B on the side opposite to the main body 10 side. When the infant B is held with a face-to-face hug or a forward-facing piggyback, the infant B is applied to the opposite back side, that is, the crotch side or the abdomen side. Note that the relationship between the auxiliary holding portion 20 and the waist belt portion 50 is also generally arranged in a substantially inverted T shape, and is integrally connected to the waist belt portion 50 by sewing only the lower end of the auxiliary holding portion 20. The auxiliary holding part 20 can also be bent in a direction perpendicular to the surface direction of the part 50.

The auxiliary holding part 20 of the present embodiment has its lower end fixed together with the main body part 10 by sewing to the waist belt part 50, but is attached to the waist belt part 50 at one end (lower end part) on the fixing side. connection width W ₂ that is connected is narrower than the connection width W ₁ of the main body portion 10 and the waist belt part 50 is connected by stitching, inner than the connection width W ₁ of the main body portion 10 and the waist belt part 50 On the other hand, it is sewn to the waist belt portion 50 together with the main body portion 10 at the sewing line 13b, and has a substantially trapezoidal shape gradually widened toward the other end side of the free end extending upward.

For example, the auxiliary holding portion 20 is sewed to the waist belt portion 50 at the connection lateral width W ₂ (see FIG. 6) of one end portion (lower end portion) that is sewn to the waist belt portion 50 and connected to the lower end portion of the main body portion 10. and which is set within a range of 50% to 90% of the connection width W ₁ of the lower end portion of the main body portion 10, even if the infant B is held at a lower position, as described below, to compress the groin of the baby B And the movement of the leg of the infant B is difficult to be restricted.

In particular, in the auxiliary holding part 20 according to the present embodiment, the outer edges on both the left and right sides from which the legs of the infant B with the buttocks received by the positioning pedestal part 30 to be described later are projected from the upper free end side to the lower waist belt part 50. And the waist belt portion 50 with the lateral width being gradually narrowed downward (90 °) vertically toward the connection side to the main body 10 or with an inclination of more than 90 ° and 140 ° or less. It is connected to the lower end of the main body 10.
As a result, the leg movement of the infant B is prevented from being restrained even when the infant B with a low age before sitting on the neck is held at a high position, as will be described later. A natural posture that is less burdensome for younger infants B without spreading more than necessary, and an open leg posture of about 130 ° is ideal, but it leads to a form close to the natural open leg posture, The load on the body shape of the infant B in the leg state is minimized.

  As shown in FIGS. 6 and 8, the auxiliary holding portion 20 has a vertical length (vertical width dimension) that is approximately the same as the abutment portion 13 of the main body portion 10, and the infant B When the auxiliary holding portion 20 is disposed opposite to the holding portion 13 of the main body portion 10, the left and right ends of the holding portion 13 are smaller than the area of the holding portion 13. The holding part 13 is larger to the extent that the part 13B starts to protrude.

In the baby carrier 1 according to the present embodiment, the auxiliary holding part 20 is interposed between the user M and the infant B, and the user M and the infant B do not directly contact with each other. It is difficult to collect between the person M and the infant B. Therefore, it is difficult for the infant B and the user M to get stuffy, and discomfort can be reduced. Moreover, the auxiliary | assistant holding | maintenance part 20 intervenes between the user M and the infant B, and it can prevent the wrinkles produced by the body temperature of the infant B from entering the clothing of the user M.
Such an auxiliary holding part 20 is also formed of a material having predetermined flexibility and flexibility so that the body shape of the infant B is not excessively added. While the auxiliary holding part 20 is applied to the body of the infant B, the back side of the auxiliary holding part 20 touches the user M side. By improving the ventilation of the part and releasing moisture and heat, it is possible to prevent partial temperature rise and stuffiness, and to reduce discomfort due to heat and stuffiness. That is, by using a material having air permeability, moisture and heat such as stuffiness of the infant B and the user M can be released, and an abnormal heat retention state does not occur between the infant B and the user M.

  In the case of carrying out the present invention, as such a configuration of the auxiliary holding portion 20, for example, the entire auxiliary holding portion 20 is a connecting yarn that forms an air layer having a specific thickness between the front and back mesh fabrics. It is also possible to form it with a three-dimensional knitted fabric (double raschel) woven with woven fabric, or to have a structure in which the front or back surface is covered with an exterior fabric. Further, the auxiliary holding part 20 may be composed of only one or two or more exterior fabrics, preferably the entire auxiliary holding part 20, only with a breathable mesh-structured cloth that allows air to flow on the front and back. A cushioning material such as urethane or a three-dimensional network structure may be placed in an exterior fabric made of a front fabric and a back fabric.

  In particular, when a three-dimensional knitted fabric (double raschel) is used, the woven fabric body maintains a breathable air layer as a whole, and convection does not occur in the air layer due to the connecting yarn woven between the front and back meshes. Since the heat insulating effect is high and the volume is large, the heat insulating action can be maintained for a long time. In addition, it has a volume that can store moisture against the generation of moisture such as sweat, and the movement of the user M and the movement of the infant B become the volume change of the woven fabric body, and the woven fabric body is held. The high-temperature air and high-humidity air are discharged, and low-humidity and low-temperature air is introduced from the outside. In other words, moisture and heat are likely to escape. Therefore, an increase in moisture is prevented, and sweat sweated from the body of the user M or the body of the infant B is quickly absorbed by the woven fabric body, and heat and stuffiness are remarkably reduced. Therefore. Occurrence of sweat rash is prevented, and measures against sweating, heat and stuffiness, and sweat rash. And even when the infant B is held, the feeling of tingling and stickiness does not occur. Furthermore, even when the baby B is held, there is no sense of incongruity due to the following change of the woven fabric body.

  In addition, as a cushioning material to be put into the exterior fabric, even when a continuous linear body made of resin is irregularly meandering and intertwined, and a three-dimensional network structure that is adhered in a meandering state is disposed. It has a volume capable of accommodating moisture such as sweat of the infant B or the user M, and the space between the continuous striatum is continuous, and moisture and heat are less likely to be accumulated due to a high porosity. In particular, if the whole or part of the three-dimensional network structure is covered with a breathable fabric, fresh air is taken in, and the volume of the air layer changes due to the movement of the user M and the movement of the infant B. Therefore, high-temperature air and high-humidity air are discharged, and low-humidity and low-temperature air is introduced from the outside. Therefore, the heat and moisture of the body of the user M and the infant B can be released, the heat and stuffiness can be reduced, and the feeling of stickiness and stickiness when holding the infant B is reduced. Further, even when the baby B is held, there is no sense of incongruity due to the following change of the three-dimensional network structure.

  In the baby carrier 1 of the present embodiment, since the mechanical strength is mainly entrusted to the main body 10 that receives the infant B in a wide area and supports and protects the body of the infant B, the entire auxiliary holding part 20 is entrusted. However, the mechanical strength does not need to be as strong as that of the main body 10, but a part of the weight of the infant B is also applied to the auxiliary holding portion 20. In addition, since the auxiliary holding unit 20 has at least the outer surfaces of the front and back sides of the same configuration as the main body unit 10, the auxiliary holding unit 20 and the main body unit 10 have a sense of unity and look good. When implementing the above, a different configuration may be adopted.

  And in the baby carrier 1 of this Embodiment, the cloth of predetermined length which has the connection insertion tool 23 of the buckle with an adjuster in the front-end | tip via the connection cloth 25 in the right-and-left both ends by the side of the free end of the auxiliary | assistant holding | maintenance part 20. A pair of left and right connection adjusting portions 22 formed of a belt are attached, and a connection difference is formed near the boundary between the backrest portion 12 and the abutment portion 13 on the left and right sides of the outer surface side of the main body portion 10 (the opposite side to the infant B side). A connection receiver 24 of a buckle corresponding to the engagement of the insertion tool 23 is attached, and by the connection engagement of the connection insertion tool 23 and the connection reception tool 24, the left and right side parts on the free end side of the auxiliary holding part 20 A connecting portion having a predetermined length is formed to connect the backrest portion 12 of the main body portion 10 and the left and right sides in the vicinity of the boundary of the heel portion 13.

  Therefore, in the baby carrier 1 of the present embodiment, the auxiliary holding portion 20 sewn to the waist belt portion 50 together with the main body portion 10 on the infant B side (inner surface side) of the main body portion 10 is connected and adjusted on both right and left sides. The distance between the main body part 10 and the auxiliary holding part 20 by being connected to the main body part 10 by the connection part 21 having a predetermined length formed by the connection engagement of the part 22 and the connection plug 23 and the connection receiver 24 ( Distance) is fixed, and the infant B is positioned in a space formed between the main body 10, the auxiliary holding part 20 and the connection part 21. Thus, the infant B is accommodated between the main body part 10, the auxiliary holding part 20, and the connection part 21, and the main body part 10 is applied to the back side of the infant B in the face-to-face hug and the forward facing piggyback. The auxiliary holding part 20 is assigned to the abdominal side, and the infant B is held by the connecting part 21 so as not to fall sideways. In particular, the leg of the infant B is passed through the annular opening formed between the left and right side edges of the main body 10 and the left and right side edges of the auxiliary holding part 20 below the connection part 21. The situation where the infant B falls from the side of the head rest 11 of the main body 10 due to the bowing of the infant B due to the restriction of the accommodation space of the infant B or the user M's forward bending posture, etc. Can be prevented. Further, even when the position of the baby B is moved with respect to the user M by switching the holding and the piggyback, the infant B can be prevented from falling and the user M can easily switch the holding and the piggyback even if not skilled. And

  In particular, the length of the connection portion 21 can be adjusted by adjusting the length of the pair of connection adjustment portions 22 of a predetermined length by the adjuster function of the connection insert 23 of the buckle. Thus, the interval (distance) between the main body portion 10 and the auxiliary holding portion 20 can be freely adjusted. Thus, the optimal distance between the infant B and the user M can be adjusted with an appropriate close contact distance with the user M where the infant B does not feel cramped. Therefore, the infant B can be held in such a manner that the body position is stabilized with little shaking by the infant B, and a comfortable holding feeling with less burden on both can be obtained by the sense of unity between the user M and the infant B.

  In the present embodiment, since the connection insertion tool 23 and the connection receiver 24 are freely connectable, depending on the convenience of the user M, the connection insertion tool 23 and the connection receiver 24 can be connected and engaged. In the state where the main body part 10 and the auxiliary holding part 20 are connected by the connection part 21, the baby B can be taken in and out between the main body part 10 and the auxiliary holding part 20, and the connection plug 23 and the connection receiver Even when the free end side of the auxiliary holding part 20 is separated from the main body part 10 by releasing the connection engagement 24, the baby B can be put in and out between the main body part 10 and the auxiliary holding part 20.

  Furthermore, in the present embodiment, the adjuster can be adjusted even when the main body 10 and the auxiliary holding part 20 are connected by the connecting part 21 by the connecting engagement of the connecting plug 23 and the connecting receiver 24 by the buckle with the adjuster function. The distance between the two can be freely adjusted by the function, and the baby B is accommodated in the space formed between the main body 10, the auxiliary holding part 20 and the connecting part 21. However, in the case of carrying out the present invention, an adjuster function may be provided in both the connection plug 23 and the connection receiver 24, or either one of them may be adjusted. Or the adjuster function may be made independent. In addition, the means for connecting the main body 10 and the auxiliary holding part 20 is not limited to the engagement of the buckle, but as a coupling engagement using a coupling tool such as an eggplant, a carabiner, a spring hook, a D lock, a quick catch, or an elliptical ring. Alternatively, the connection may be made using a stretchable member such as a stretchable rubber band or rubber tape. For example, rubber that is elastically stretchable in the longitudinal direction and that is designed by wrapping a flat rubber having a width of about 3 cm to 10 cm with a cloth or the like that extends to such an extent that an infant B can be inserted between the main body 10 and the auxiliary holder 20.

That is, the infant B can be easily guided to a state where the center of gravity is placed on the buttocks rather than the knee, and can be held in a stable holding form with little burden on the infant B. Furthermore, the degree of freedom of movement of the leg of the infant B is high, and the movement of the infant B in the M-shape is likely to be free. Therefore, hip dislocation can be prevented and the burden on the infant B is less.

  Furthermore, according to the baby carrier 1 of the present embodiment, the center portion 13A and the end portion 13B constituting the abutment portion 13 of the main body portion 10 are formed by draping and are joined together by a sewing line 13a that is curved inward. In addition, a three-dimensional space with a depth is formed by sewing to the waist belt 50 by sewing the lower end of the main body 10 and the vicinity thereof, and it is easy to drop the buttocks of the infant B Thus, the body shape of the infant B can be easily guided to the state of the M-shaped leg with the knee positioned higher than the buttocks. That is, the infant B can be easily guided to a state where the center of gravity is placed on the buttocks rather than the knee, and can be held in a stable holding form with little burden on the infant B.

Moreover, in the baby carrier 1 of the present embodiment, since the auxiliary holding part 20 is connected to the lower end of the main body part 10 with a narrower width than the main body part 10, the folding of the positioning pedestal part 30 is unfolded and the main body Even when the sinking of the buttocks of the infant B whose height has been increased is received at a low position by the positioning pedestal part 30 that passes between the part 10 and the auxiliary holding part 20 at an original length, that is, the infant B is at a low position. Even when held, the crotch width of the infant B is prevented from being unnecessarily widened to restrict the movement of the legs.
In particular, in the baby carrier 1 of the present embodiment, the width of the main body portion 10 is gradually narrower toward the backrest portion 12 above the abutment portion 13 applied from the back side of the body of the infant B to the buttocks. Therefore, the folding of the positioning pedestal 30 is unfolded, and the infant B having a height is landed on the positioning pedestal 30 where the main body 10 and the auxiliary holding part 20 are connected with the original length. Even at times, the knee joint of the infant B tends to be free.

The positioning pedestal 30 according to the present embodiment is formed integrally and continuously from the main body 10 and the auxiliary holding part 20, so that the positional deviation does not occur and the main body 10 and the auxiliary holding part 20 are moved. The connection strength is stable. In particular, in the state where the length between the main body 10 and the auxiliary holding part 20 is shortened in the positioning base part 30, the connection side between the main body 10 and the auxiliary holding part 20 by receiving the weight of the infant B mainly at the positioning part 32A. Since the bottom of the lower end is raised to support the infant B, the positioning pedestal 30 is formed integrally and continuously from the main body 10 and the auxiliary holding part 20 so as to sufficiently withstand the weight of the infant B. It has sufficient mechanical strength and is in a reliable bridge state.
Furthermore, since the adjustment tool for fixing the folding state of the positioning pedestal 30 and adjusting the length is the pair of female side 33a and male side 33b of the slide fastener 33, the fixing stability in the folded state is also provided. There is no high displacement.

  Therefore, even when the infant B is received by the positioning base 30 with the length between the main body 10 and the auxiliary holding part 20 shortened, the swinging is small and the center of gravity position of the buttocks of the infant B is easy to be stabilized, and the posture is not stable. Even if the infant B at a time when the age before the stable neck is low is an object to be held, the infant B is less likely to wobble and the load on the infant B can be reduced. That is, when the length of the positioning pedestal portion 30 disposed between the main body portion 10 and the auxiliary holding portion 20 is shortened, a stable tension is applied due to the weight of the infant B, so that the buttocks of the infant B can be received. Therefore, even in the case of an infant B of a young age, the position of the body of the infant B is stabilized and a sense of stability is obtained, and the holding posture is less burdensome.

Further, in the present embodiment, the pair of female side 33a and male side 33b of the slide type fastener 33 for adjusting the length of the positioning pedestal 30 is the back side opposite to the side receiving the buttocks of the infant B. Therefore, the pair of female side 33a and male side 33b of the sliding fastener 33 does not directly touch the body of the infant B who has landed. Therefore, the slide type fastener 33 is not injured, and there is little possibility of causing discomfort and discomfort.
Of course, since the positioning pedestal 30 is integrally formed continuously from the main body 10 and the auxiliary holding part 20 and there is no detachable member for attaching the positioning pedestal 30 to the main body 10 and the auxiliary holding part 20, There is no sense of discomfort or discomfort due to the detachable member, and since the detachable member is not required, there is no possibility of losing the positioning base 30.

In addition, a pair of females of the slide type fastener 33 is used as a positioning portion for supporting the weight of the buttocks by receiving the buttocks of the infant B on the positioning base 30 with the length between the main body 10 and the auxiliary holding unit 20 shortened. Although the description has been given of the position 32A where the folded portion 32a folded in the length direction between the side 33a and the male side 33b is brought down to the second abutting portion 31 side and overlapped with the abutting portion 31. When the infant B is received at the positioning portion 32A, the foldable portion 32a may be used while being superimposed on the second abutment portion 31, or the foldable portion 32a may be superimposed on the abutment portion 31. You may use it in the state arrange | positioned on the crotch side of the infant B without it. Thus, the height position of the buttocks of the infant B can also be adjusted by selecting the folding of the folding part 32a on the second abutment part 31. In particular, when the foldable portion 32a is overlapped with the second abutment portion 31, the mechanical strength is high, the position of the buttocks of the infant B is stabilized, and the stability of the holding position is increased.
In addition, it is also possible to separately provide a means for fixing the folded portion 32a to the second abutment portion 31 in an overlapped state.

  Further, in the above embodiment, the positioning pedestal portion 30 is connected at a height (length) position of 10 cm from the lower end near the middle of the auxiliary holding portion 20, but when implementing the present invention, It is possible to connect at a lower position, or the length of the positioning pedestal 30 may be increased to connect at a higher position. In any case, even when the infant B is held at a high position by the positioning pedestal portion 30 with the length between the main body portion 10 and the auxiliary holding portion 20 shortened, the lower end of the main body portion 10 and the auxiliary holding portion 10 is usually set. Even if the bending due to the weight of the infant B is taken into consideration than the original depth, it is designed to be raised by about 5 cm to 10 cm. Further, the connection position to the main body 10 may be lower than or higher than the boundary position between the abutment portion 13 and the backrest portion 12. Preferably, if the original length of the positioning pedestal 30 is within the range of 30 cm to 40 cm, the shaking is small and the burden on the infant B can be reduced.

Next, a usage pattern when the baby B is held using the baby carrier 1 of the present embodiment configured as described above will be described.
When the baby B is held using the baby carrier 1 of the present embodiment, the auxiliary holding portion 20 is disposed closer to the user M, and the main body portion 10 is disposed farther from the user M. The infant B is accommodated between the main body 10 and the auxiliary holding part 20. For example, as shown in FIG. 10 and FIG. 11, the face-to-face holding in which the infant B and the face of the user M face each other or the infant B on the back side of the user M as shown in FIG. 12 and FIG. In the case of a vertical forward piggyback head facing the same direction as the user M, the infant M is disposed between the main body 10 and the auxiliary holding part 20 so that the abdominal side of the body of the infant B faces the user M.

  Then, a buckle connection insertion tool 23 (reference numerals and symbols in FIGS. 10 to 13) provided on both the left and right sides of the auxiliary holding section 20 via connection adjustment sections 22 (reference numerals and symbols are omitted in FIGS. 10 to 13). (Symbol is omitted) is fitted into a buckle connection receiver 24 (not shown in FIG. 10 to FIG. 13) provided on the outer surface side of the boundary between the backrest 12 and the abutment 13 of the main body 10. By connecting the main body part 10 and the auxiliary holding part 20 on the left and right side surfaces by the connecting part 21, the interval between the main body part 10 and the auxiliary holding part 20 is limited, and the main body part 10 and the auxiliary holding part 20 are connected. The left and right inclination of the torso of the infant B accommodated between the holding unit 20 is restrained on the side surface side to prevent the infant B from falling off. Furthermore, the leg of the infant B is passed through an annular shape formed by the auxiliary holding part 20, the main body part 10, and the connection part 21, so that the main body part 10 is caused by a fall caused by the curling of the infant B, a forward bending of the user M, or the like. The infant B can be prevented from falling from the side of the head rest 11.

  In addition, a connection projecting from the boundary between the head rest part 11 and the back rest part 12 on the inner surface side (infant B side) of the main body part 10 is connected to the connection plug 43 of the rotary buckle provided on the shoulder belt part 40. The main body part 10 and the shoulder belt part 40 are connected by fitting a coupling receiver 44 of a rotary buckle attached to the tip of the part 14.

  In particular, in the baby carrier 1 according to the present embodiment, the connecting portion rich in cushioning from the surface of the boundary portion between the head rest portion 11 and the back rest portion 12 on the inner surface side (infant B side) of the main body portion 10 as described above. By projecting 14, the side of the neck and the head of the infant B can be guarded, so that the neck of the infant B and the side of the head are supported in response to the inclination of the left and right sides of the infant B. Thus, it is possible to prevent the neck of the infant B and the head from glare. Therefore, even when holding an infant B of a young age before sitting on the neck, the neck and the head can be prevented from being bent and the neck of the infant B can be prevented from bending. Less.

  A pair of left and right shoulder belts having one end fixed to the left and right upper ends of the auxiliary holding portion 20 and the other end fixed to the left and right side portions of the upper portion of the auxiliary holding portion 20 and connected to the auxiliary holding portion 20 in an annular shape. The belt 40 is hung around the waist of the user M around the shoulder of the user M, and the waist belt portion 50 disposed at the lower ends of the auxiliary holding unit 20 and the main body 10 is attached to both ends of the buckle. By fitting the connecting plug 53 and the connecting receiver 54 (the symbols and symbols are omitted in FIGS. 10 to 13), connecting them in a ring and fixing them around the waist of the user M, the baby carrier 1 It is attached to the user M. As a result, the weight of the infant B accommodated between the main body 10 and the auxiliary holding part 20 is distributed to both shoulders, back and waist of the user M, and the infant B is held by a cuddle or a piggyback.

  In addition, as described above, in the baby carrier 1 of the present embodiment, by adjusting the belt length of the adjustment belt portion 42 by the adjusters 42c and 42b of the adjustment belt portion 42 in the pair of left and right shoulder belt portions 40, The belt length of the shoulder belt portion 40 can be adjusted. Furthermore, by connecting and engaging the connection insertion tool 46c and the connection receiver 46d of the buckle of the shoulder belt adjustment portion 46 provided on the shoulder hook portion 41, the distance between the left and right shoulder belt portions 40 is fixed at a predetermined distance, The left and right shoulder belt portions 40 can be prevented from coming off the user's M shoulder. Further, the adjuster function is provided in one or both of the connection plug 46b and the connection receiver 46d, so that the length of the shoulder belt adjustment section 46 is adjusted, and the distance between the left and right shoulder belt sections 40 is determined. (Distance) can also be adjusted. In addition, the position of the shoulder belt adjusting portion 46 can be adjusted by the slide belt 47 and the belt moving adjuster 48 provided on the shoulder portion 41. Therefore, the shoulder belt 40 can be disposed at a position where the burden on the user M is low according to the body shape of the user M and the like.

  Thus, the distance between the pair of left and right shoulder belt portions 40 can be adjusted by the shoulder belt adjustment portion 46, and the length of the shoulder belt portion 40 can be adjusted by the adjusters 42c and 42b of the adjustment belt portion 42. In addition, the slide belt 47 and the belt movable adjuster 48 can adjust the position of the shoulder belt adjusting portion 46, so that it can be adjusted according to the body shape of the user M and the position of the infant B holding or carrying the infant B. Thus, it is possible for the user M to easily set the optimal position where the infant B can be easily held. Further, the distance between the infant B and the user M can be easily adjusted, and the holding posture for the infant B can be set appropriately. For this reason, even when holding an infant B of a young age whose posture is unstable, the shoulder belt portion 40 can be fitted to the body shape of the user M, and the infant B can be held in close contact with the user M and stably held. Is possible. Further, the infant B can be easily adjusted to a holding mode with less burden even when the infant B is held at a low age by adjusting the center of gravity of the buttocks rather than the knee. Furthermore, even when the baby B that has grown and grown is held, the wearing state of the shoulder belt portion 40 to the user M can be adjusted to hold the baby B in an appropriate holding posture that does not feel cramped. it can.

In the waist belt portion 50, the belt length of the waist belt portion 50 can be adjusted by adjusting the length of the length adjusting portion 52 by an adjuster function provided on the buckle. Can be fitted around the waist and the burden on the user M can be reduced.
In the baby carrier 1 of the present embodiment, the pair of left and right shoulder belt portions 40 may be stopped after the waist belt portion 50 is fastened to the waist of the user M. After being stopped, the waist belt portion 50 that is fastened to the waist of the user M may be stopped, which is convenient.

  And in the baby carrier 1 of this Embodiment, the positioning base part integrally formed continuously from the main-body part 10 and the auxiliary holding part 20 between the main-body part 10 in which the infant B is accommodated, and the auxiliary holding part 20 In the positioning pedestal portion 30, a pair of the female side 33a and the male side 33b of the sliding fastener 33 are attached at a predetermined distance. For this reason, by engaging the pair of female side 33a and the male side 33b of the slide type fastener 33 and closing the fastener, a part in the length direction of the positioning base 30 can be fixed in the folded state, 10 and the auxiliary | assistant holding | maintenance part 20 can be shortened. That is, the positioning pedestal 30 can freely adjust the depth between the main body 10 and the auxiliary holding part 20 and can adjust the sinking depth of the buttocks of the infant B.

  Therefore, for example, as shown in FIG. 10, when the infant B is held in a face-to-face holding in which the infant B and the face of the user M face each other, Since the position of the buttocks of the infant B can be increased by the positioning pedestal portion 30 in which the connection length between the auxiliary holding portions 20 is shortened, the main body portion 10 and the auxiliary holding portion 20 may sink or be buried. The head support part 11, the back support part 12 and the heel support part 13 of the main body part 10 are applied to the appropriate positions of the body of the infant B, so that the burden on the infant B can be reduced and comfortable holding is possible. .

  In particular, even in the case of a low-age infant B who has an unstable posture before sitting on the neck, the back support part 12 and the abutment part 13 of the main body part 10 are assigned to appropriate positions of the body of the infant B, The head support part 11 of the main body part 10 is appropriately disposed on the head of the infant B, and further, from the surface of the boundary part between the head support part 11 and the back support part 12 on the inner surface side (infant B side) of the main body part 10. Since the projecting connecting portion 14 having a high cushioning property can guard the neck and the side of the head of the infant B, the neck and the head of the infant B are appropriately supported by the rear and the side of the head. Even with a low-age infant B who is likely to be burdened by vibration caused by walking of the user M or the like, the burden on the body of the infant B, particularly the head and neck, can be reduced.

Further, the buttocks of the infant B are placed on the positioning pedestal portion 30 in a state where the pair of the female side 33a and the male side 33b of the sliding fastener 33 are engaged to shorten the connection length between the main body portion 10 and the auxiliary holding portion 20. In the positioning portion 32A where the sun sinks, the lateral width W ₃ in the left-right direction (horizontal direction) is 5/10 to the lateral width W ₁ of the lower end of the main body portion 10 (= the connection width where the main body portion 10 is connected to the waist belt portion 50). 9cm, more preferably narrow within the range of 3/5 to 4/5, and at the auxiliary holding part 20, at least 15 cm from the position connected to the lower end of the main body part 10. Since the horizontal width up to the height is formed to be 1.4 times or less the horizontal width of the positioning portion 32A, even if the infant B of a young age whose posture before the neck is unstable is unstable, the infant B Crotch width is expanded more than necessary, legs Movement, is prevented from or is particularly restricted movement of the knee joint. Therefore, the body shape of the infant B can be held in a natural posture in which the body shape of the infant B is opened in an M shape with the knee positioned higher than the buttocks, and the body shape of the infant B is less burdensome.

  In particular, according to the baby carrier 1 of the present embodiment, the leg of the infant B with the buttocks sunk in the positioning portion 32A of the positioning base portion 30 in which the connection length between the main body portion 10 and the auxiliary holding portion 20 is shortened. The lower end of the main body 10 is inclined at an angle within a range of 90 ° to 140 ° at a height of 15 cm from a position connected to at least the lower end of the main body 10 of the auxiliary holding portion 20 extending from the left and right sides. Because it is connected to the hips, compression of the hips and hips is possible without interfering with the natural leg of infant B when the age is low before the neck is sitting, which is ideal for a leg of about 130 ° There are few.

  Furthermore, according to the baby carrier 1 of the present embodiment, the abutment formed by draping that is joined to the both sides of the second abutment portion 31 of the positioning pedestal portion 30 by the inwardly curved sewing line 13a. The vicinity of the boundary between the central portion 32A of the portion 13 and the left and right end portions 32B is exposed, and the left and right end portions 13B can be bent toward the infant B side with respect to the central portion 13A, and has a depth. A three-dimensional space can be formed. Therefore, the movement of the infant B accommodated between the main body part 10 and the auxiliary holding part 20 in a leg-shaped manner tends to be free.

  In addition, the center portion 32A of the abutment portion 13 and the left and right end portions 32B formed by draping that are joined together by the inwardly curved sewing line 13a allow predetermined flexibility and allowance in the holding state of the infant B. A central portion 13A formed of a material having flexibility, elasticity, buffering properties, and the like is easily bent backward. Accordingly, the buttocks of the infant B are likely to fall down, the infant B is more likely to be positioned at the center of gravity than the knee, and the holding state is low even when the infant B is held at a low age, and the position of the buttocks of the infant B is appropriate. It is stabilized at the position, and the holding stability of the infant B is high.

  Thus, according to the baby carrier 1 of the present embodiment, it is possible to stably hold an open leg posture with less burden even when the infant B at a time when the age before sitting on the neck is low is held forward.

  In addition, as shown in FIG. 12, in the case where the infant B is turned forward on the back side of the user M in the same direction as the user M, the positioning pedestal portion that connects between the main body portion 10 and the auxiliary holding portion 20. Since the length of 30 can be shortened to raise the position of the buttocks of the infant B, the position of the infant B can be held at a position further away from the position of the waist of the user M. Therefore, the spine of the user M and the infant The shape of the curved spine line of the infant B easily follows the shape of the curved spine line of the user M without repulsion of the spine of the B, so that the infant B can easily adhere to the user M. Therefore, it is possible for the user M and the infant B to hold comfortably with a comfortable posture. In particular, the user M carrying the infant B is less likely to feel the weight of the infant B than the baby and can easily hold it. In addition, since the infant B easily comes into close contact with the user M, the infant B is unlikely to be warped backward.

On the other hand, in the state where the main body 10 and the auxiliary holding part 20 are connected by the original length of the positioning base part 30 without engaging the pair of female side 33a and male side 33b of the sliding fastener 33, positioning is performed. Since the pedestal portion 30 overlaps and follows the main body portion 10 and the auxiliary holding portion 20, as shown in FIGS. 11 and 13, the sinking depth of the buttocks of the infant B received by the positioning pedestal portion 30 becomes deeper.
Therefore, even when the infant B grows up and becomes taller, the positioning base 30 having the original length between the main body 10 and the auxiliary holding part 20 positions the buttocks of the infant B at a low position. By doing so, the head support part 11, the back support part 12 and the heel support part 13 of the main body part 10 are assigned to appropriate positions of the body of the infant B, thereby enabling a comfortable holding with a small burden on the infant B. .

  As shown in FIG. 13, even when the infant B's buttocks are landed on the positioning pedestal 30 having the original length between the main body 10 and the auxiliary holding portion 20, the assisting portion is supported. The holding part 20 and the main body part 10 are connected by the connecting part 21, and the leg of the infant B is passed through the ring formed by the auxiliary holding part 20, the main body part 10 and the connecting part 21, so that the infant B warps back. Can prevent falling by.

As described above, according to the baby carrier 1 of the present embodiment, the length of the positioning pedestal portion 30 disposed and disposed on the inner surface side between the main body portion 10 and the auxiliary holding portion 20 is the sliding fastener 33. Since the pair of female side 33a and male side 33b are adjustable, the height of the infant B and the height position of the infant B to be held can be adjusted according to the holding form of the infant B or the piggyback.
In particular, the lateral dimension of the positioning portion 32A where the infant B is received by the positioning base 30 when the length passing between the main body 10 and the auxiliary holding part 20 is shortened and the assist applied to the crotch side of the body of the infant B By specifying the width dimension of the holding portion 20, even an infant B at a low age can stably hold with little burden, and an open leg that does not place a burden according to the age, size, and growth of the infant B Can be held in a posture.
A pair of female side 33a and male side 33b of the slide type fastener 33 for adjusting the length of the positioning pedestal 30 are attached to the back surface of the positioning pedestal 30 opposite to the landing side of the infant B. Therefore, the height position of the buttocks of the infant B can be adjusted without causing the infant B to feel uncomfortable or uncomfortable.

  As described above, the baby carrier 1 according to the above embodiment includes the main body 10 that is applied to the body of the infant B on the opposite side to the user M side and supports the infant B, and the lower end of the main body 10. And the auxiliary holding part 20 applied to the body of the infant B on the opposite side of the main body part 10 and the main body part 10 and the auxiliary holding part 20 on the opposite side of the main body part 10 and the auxiliary holding part 20 from the main body part 10 and the auxiliary holding part 20 It is formed continuously and passed between the main body part 10 and the auxiliary holding part 20, and is adjusted by the folding length adjustment by the pair of female side 33a and male side 33b of the slide type fastener 33. A positioning pedestal 30 for adjusting the depth between the main body 10 and the auxiliary holding part 20 by adjusting the length between the auxiliary holding parts 20 and positioning the sinking depth of the buttocks of the infant B; Connected to the holding unit 20 to hold the infant B A pair of shoulder belt portions 40 that are hung on the shoulders of the user M, and a waist belt portion 50 that is connected to the lower end portions of the main body portion 10 and the auxiliary holding portion 20 and is worn around the waist of the user M. Is.

  Therefore, according to the baby carrier 1 according to the above-described embodiment, the infant housed between the main body 10 and the auxiliary holding portion 20 on the positioning base 30 disposed between the main body 10 and the auxiliary holding portion 20. B is received, but a pair of female side 33a and male side 33b of slide type fastener 33 attached to the back surface of positioning pedestal portion 30 at a predetermined distance are engaged, and length adjustment portion 32 is folded. When the length of the positioning pedestal 30 between the main body 10 and the auxiliary holding part 20 is shortened, the sinking depth of the buttocks of the infant B accommodated between the main body 10 and the auxiliary holding part 20 becomes shallow. When the folding of the height length adjustment unit 32 is expanded to increase the length of the positioning base 30 between the main body 10 and the auxiliary holding unit 20, the height adjustment unit 32 is accommodated between the main body 10 and the auxiliary holding unit 20. Infant Sinking depth of the buttocks is deep, you can adjust the height of the infant B holding by adjusting the length of the positioning pedestal 30.

  Therefore, even in a small-age infant B with a small body, the length of the positioning pedestal 30 between the main body 10 and the auxiliary holding unit 20 is shortened by folding the length adjusting unit 32, and the lower end of the main body 10 Since the infant B can be held at a position higher than the connection position of the lower end portion of the auxiliary holding part 20, the infant B does not sink or be buried between the main body part 10 and the auxiliary holding part 20, The position of the head of the infant B is appropriately arranged on the head support part 11 of the main body part 10 that protects the infant B, so that the burden on the infant B can be reduced and comfortable holding is possible. Further, when the infant B grows and the body becomes large, the length adjustment unit 32 is expanded and the length of the positioning base 30 between the main body 10 and the auxiliary holding unit 20 is increased. The infant B is held at a low position on the connection side between the lower end of the main body 10 and the lower end of the auxiliary holding part 20, and the head rest 11, the back rest 12, and the saddle rest 13 of the main body 10 are held by the infant B. Protects the body at an appropriate position and enables comfortable holding. Also, the height position of the infant B can be adjusted to a comfortable holding position for the user M. The holding height position of the infant B is adjusted according to the age, size, and growth of the infant B that is held in this way, and the infant B and the user M can be held with less burden.

In addition, since the positioning pedestal portion raises the sinking depth of the buttocks of the infant to the upper level, the opening width of the crotch width of the infant is not affected by the width of the lower end portion of the main body, and the positioning pedestal Since the infant can fit the leg into the space from the lower part of the part to the closed lower end where both the auxiliary holding part and the main body part are connected, the hip joint is opened for younger infants. It is possible to prevent overshoot.
Further, since the positioning base 30 for receiving the buttocks of the infant B is formed integrally and continuously from the main body 10 and the auxiliary holding part 20, the connection strength is stable without causing a displacement. The positioning base part 30 is not detached from the main body part 10 and the auxiliary holding part 20 due to the weight of the infant B, and the reliability is high, and the collar part is received by the positioning base part 30 whose length is shortened. It is difficult for the infant M to swing even by vibration caused by the user's walking, etc., and the center of gravity position of the buttocks of the infant B is easy to be stabilized. And can be held stably.
In this way, the holding height position of the infant B can be adjusted, and it is possible to maintain an open leg posture that does not impose a burden according to the age, size, and growth of the infant B, and the age is low. Even the infant B at the time allows stable holding with little burden.

In particular, the positioning pedestal 30 of the baby carrier 1 according to the above-described embodiment is configured to engage a pair of female side 33a and male side 33b of a slide type fastener 33 that is attached to the back surface thereof by a predetermined distance apart. The width W ₃ of the positioning portion 32A as the sinking horizontal width of the buttocks of the infant B when the length between the main body portion 10 and the auxiliary holding portion 20 is shortened by the folding is fixed. It is formed in a width within a range of 5/10 to 9/10 of the lateral width W ₁ of the lower end portion of the main body portion 10 connected to the auxiliary holding portion 20, more preferably within a range of 3/5 to 4/5. Yes.

In the positioning pedestal 30, the lateral width W ₃ of the positioning part 32A where the buttocks of the infant B are received when the length between the main body 10 and the auxiliary holding part 20 is shortened by folding in the length direction, that is, the infant B retention buttocks sink width W _3, from being formed in the narrow width in the range of 1 / 3-2 / 3 of the width W ₁ of the lower end portion of the main body portion 10, a low-old infants B before sitting neck Even as a subject, the hip width of the infant B is unnecessarily widened, and the hip joint is prevented from opening too much, dislocation of the hip joint is prevented, and it is possible to hold the load with a natural open leg posture with an M-shaped open leg. To do.

In addition, the auxiliary holding part 20 of the baby carrier 1 according to the above embodiment has an auxiliary width between the left and right sides from the connection position with the lower end of the main body part 10 to a height position of 15 cm at the maximum. it is not more than 1.4 times the width W ₃ of the positioning portion 32A as buttocks sink width of infant B when shortening the length between the holding portion 20.
In particular, in the auxiliary holding part 20, the width between the left and right sides from the connection position with the lower end part of the main body part 10 to the height position of 15 cm is short at the maximum between the main body part 10 and the auxiliary holding part 20. Since the width W ₃ of the positioning portion 32A at which the buttocks of the infant B are received when it is, that is, 1.4 times or less of the sinking width W ₃ of the buttocks of the infant B, the infant B of the young age before the neck is held is held. As a target, leg movements, especially knee joint movements, are not restrained, and infant B's cramped feeling is also released, allowing a less legible holding with a natural leg position with an M-shaped leg. And

As described above, the baby carrier 1 according to the embodiment is connected to the main body 10 that is applied to the body of the infant B on the opposite side to the user M side and supports the infant B, and the lower end of the main body 10. The auxiliary holding part 20 applied to the body of the infant B on the side opposite to the main body part 10, and the main body part 10 and the auxiliary holding part 20 on the opposite side of the main body part 10 and the auxiliary holding part 20, continuously from the main body part 10. The main body part 10 and the auxiliary holding part 20 are formed and arranged between the main body part 10 and the auxiliary holding part 20 and are adjusted by the folding length of the pair of female side 33a and male side 33b of the slide fastener 33. A positioning pedestal 30 for positioning the sinking depth of the buttocks of the infant B, and the auxiliary holding part 20 to freely adjust the depth between the main body part 10 and the auxiliary holding part 20 by adjusting the length between 20 The user who is connected to and holds the infant B A pair of shoulder belts 40 to be hung on the shoulders of the body, and a waist belt part 50 connected to the lower end part of the main body part 10 and the auxiliary holding part 20 and mounted around the waist of the user M, and a positioning base part 130 is a horizontal width W ₃ of the buttocks of the infant B when the length between the main body portion 10 and the auxiliary holding portion 20 is shortened, and is 5 / 10-9 / 9 of the lateral width W ₁ of the lower end portion of the main body portion 10. 10, more preferably, a width within a range of 3/5 to 4/5, and the auxiliary holding portion 20 is within a range of 15 cm from the connection position with the lower end of the main body portion 10. height width of the left and right sides to the position of the inner is at most, less than 1.4 times the buttocks sink width W ₃ of infant B when shortening the length between the main body portion 10 and the auxiliary holding portion 20 It is.

That is, the baby carrier 1 according to the above-described embodiment is attached to the user M by a pair of left and right shoulder belt portions 40, applied to the body of the infant B and supporting the infant B over a wide area, One end of the main body 10 is connected to the lower end of the main body 10, and the auxiliary holding section 20 is applied to the body of the infant B on the opposite side of the main body 10. And a positioning pedestal 30 that is passed between the auxiliary support 20 and positions the sinking depth of the buttocks of the infant B. In the positioning pedestal 30, the main body 10 is adjusted by adjusting the length of the positioning pedestal 30. The width of the sinking width W ₃ of the buttocks of the infant B when the length between the main body 10 and the auxiliary holding portion 20 is shortened can be adjusted as the bottom end of the main body portion 10. 5/10 or more of the width _{W 1} of the part In the range of 9/10 or less, more preferably in the range of 3/5 or more and 4/5 or less, and in the auxiliary holding part 20, the lower end of the main body part 10 The horizontal width of the left and right sides from the connection position to the height position of 15 cm is 1.4 times the maximum width of the sinking width of the buttocks of the infant B when the length between the main body portion 10 and the auxiliary holding portion 20 is shortened at the maximum. It is the following.

Therefore, according to the baby carrier 1 according to the embodiment, positioning the base portion 30, the width W ₃ to sink the buttocks of the baby B when shortening the length between the main body portion 10 and the auxiliary holding portion 20 The width of the width W ₁ of the lower end of the main body 10 is within a range of 5/10 to 9/10, more preferably within a range of 3/5 to 4/5, and the auxiliary holding unit 20 is formed. Infant B when the width between the left and right sides from the connection position with the lower end of the main body 10 to the height position of 15 cm is at most short between the main body 10 and the auxiliary holding part 20 Because it is 1.4 times or less of the sinking width of the buttocks, even if the infant B is to be held before the neck is held, the crotch width of the infant B is widened more than necessary and the hip joint is too open or leg Hip dislocation is prevented without restraining the movement of the To enable the less retention of the burden in a natural open leg posture to open leg.
Further, since the lower end of the main body 10 is a predetermined width wider than the horizontal width of the buttocks of the infant B when the length between the main body 10 and the auxiliary holding part 20 is shortened, the positioning base 20 can be folded. Even when the buttocks of the infant B are received on the positioning base 30 by extending the length of the main body 10 and the auxiliary holding part 20 so as to be extended, the infant can be accommodated by an appropriate wide dimension at the lower part of the main body 10. The buttocks of B are widely covered and stable holding is possible without placing a burden on the open leg posture. Furthermore, since the crotch width of the infant B is opened and held with an appropriate width, a feeling of close contact with the user M is obtained and a sense of security is increased, thereby providing a comfortable holding feeling.

Then, when the length between the main body part 10 and the auxiliary holding part 20 is shortened by folding in the length direction, the lateral width W ₃ of the positioning portion 32A where the buttocks of the infant B are received, that is, the sinking lateral width of the buttocks of the infant B Since the lower end portion of the main body 10 is wider than W _3, the buttocks of the infant B are placed on the positioning pedestal 30 that has been folded and extended between the main body 10 and the auxiliary holding portion 20. Even when it is received, the buttocks of the infant B are widely covered by the appropriate wide dimensions of the lower portion of the main body portion 10 and can be stably held without placing a burden on the open leg posture.

  Further, since the positioning pedestal portion 30 is integrally formed continuously from the main body portion 10 and the auxiliary holding portion 20, a cushioning material or the like to be attached to the main body portion 10 and the auxiliary support portion 20 is separately prepared for raising the bottom. Since it is not necessary, there is no risk of losing it, and it is possible to hold it comfortably without the stuffiness or heat of the cushioning material.

  Thus, according to the baby carrier 1 according to the above-described embodiment, the holding position of the baby B can be adjusted, and the baby carrier 1 is held in an open leg posture that does not impose a burden according to the growth of the baby B. In addition, the infant B at a low age can be stably held with little burden, and even if the infant B is held for a long time, the fatigue of the infant B can be reduced. And since the burden to the infant B is small, it is advantageous for laying down especially when the infant B of a low age is held, and a comfortable sleep environment can be created.

  Moreover, the auxiliary | assistant holding | maintenance part 20 of the baby carrier 1 which concerns on the said embodiment is a horizontal lower end which is a connection side with the lower end part of the main-body part 10, and the right-and-left both-sides edge from there to a height position of 15 cm. The formed angle is in the range of 90 ° to 140 °.

  Here, the angle between the lower end in the horizontal direction, which is the connection side with the lower end of the main body 10, and the left and right side edges to the height position of 15 cm is within the range of 90 ° to 140 °. In the auxiliary holding part 20, the positioning pedestal part 30 when the length between the main body part 10 and the auxiliary holding part 20 is shortened within the height range from the lower end connected to the main body part 10 to 15 cm. The edges of both sides of the auxiliary support part 20 touch both legs of the infant B that is received at the high position by receiving the buttocks, so that the edges of both sides of the auxiliary support part 20 that touch the legs of the infant B are touched. By setting the inclination within the range of 90 ° to 140 ° with respect to the horizontal direction of the lower end, when the infant B in the low-age period before sitting on the neck is to be held, the hip joints and buttocks of the body of the infant B Ideal for the infant B Is obtained easily leads naturally form close to the open leg posture of a about 130 °.

  Therefore, according to the baby carrier 1 according to the above-described embodiment, the auxiliary holding portion 20 has the lower end in the horizontal direction that is the connection side to the lower end portion of the main body portion 10 and the left and right sides from there to a height position of 15 cm. Since the angle formed by the edge is in the range of 90 ° or more and 140 ° or less, it does not interfere with the natural legging of infants at low ages, especially when the leg of about 130 ° is ideal. In addition, the infant's body is less pressed against the hip joints and buttocks, and the infant's body shape can be held with less burden. Therefore, even when the infant B at a time when the age before the neck sitting is low, which is ideal for the 130 ° open leg posture, can be led to a posture close to the open leg posture.

  Furthermore, when the baby carrier 1 according to the present embodiment folds the positioning pedestal portion 30 in the length direction to shorten the length between the main body portion 10 and the auxiliary holding portion 20, the folded portion 32a is an infant B. Since it becomes the positioning part 32A which catches the buttocks, the sense of stability increases by increasing the volume of the folded part 32a. Moreover, the thickness of the positioning part 32A, that is, the height can be adjusted by selecting the folding overlap, and the selection range of the position of the holding height of the infant B is widened.

Furthermore, the main body 10 of the baby carrier 1 according to the present embodiment is such that the left and right end portions 13B of the main body portion 10 of the baby support portion 13 can be bent toward the infant B side with respect to the center portion 13A. The space in which the space is accommodated forms a three-dimensional space with a depth. Therefore, according to the baby carrier 1 according to the present embodiment, even if the infant B at the age of a low age is held and protected so as to cover (wrap) the entire buttocks of the infant B, the leg is opened in an M shape. The movement is not easily restrained, the cramped feeling of the infant B is released, and the infant B at a time when the age is low can be held with less burden. Further, when viewed from the outer surface side opposite to the infant B side, it is possible to give a clean impression that is three-dimensional and slim. Furthermore, it is easy to maintain a natural open leg posture with an M-shaped open leg where the knee is bent at a position higher than the position of the buttocks of the infant B, and the center of gravity of the infant B is guided to a holding form on the buttocks instead of the leg side. It becomes easy, and holding with little burden is enabled by the body shape of the infant B.
More preferably, it can be bent by joining by draping, and the waist belt part 50 can be bent by sewing curved toward the center side (inner side) at the joining part, or by sewing the lower end of the main body part 10 and the vicinity thereof. By stitching together, the depth of the baby B is further increased, and the buttocks of the infant B can be easily lowered, and the position of the center of gravity is determined from the position of the buttocks of the infant B, thereby reducing the burden on the body shape of the infant B.

  In addition, in the baby carrier 1 according to the present embodiment, the weight of the infant B is provided by having a waist belt portion 50 that is connected to the lower portion of the main body portion 10 and the auxiliary holding portion 20 and is worn around the waist of the user M. Is distributed over the shoulder, back and waist of the user M to lighten the burden on the shoulder of the user M. However, when the present invention is implemented, the waist belt portion 50 can be omitted. is there. That is, since the infant B is held by the infant B being disposed between the main body 10 and the auxiliary support part 20, the waist belt part 50 is not necessarily required, and the left and right shoulder belt parts 40 are not necessarily required. It is good also as a form which supports the weight of the infant B only and holds the infant B or rides.

In the baby carrier 1 of the above embodiment, the shoulder belt portion 40 is connected to the auxiliary holding portion 20 in the vertical direction. However, when carrying out the present invention, the infant B can be held. If possible, the shoulder belt portion 40 may be connected to the main body portion 10, or the shoulder belt portion 40 may be connected to the main body portion 10 and the auxiliary holding portion 20. In any case, it may be configured to be connected to a position that does not interfere with the body of the infant B and to form a ring through which the shoulder of the user M is passed.
Further, the pair of left and right shoulder belt portions 40 is not limited to being mounted in parallel to the shoulder of the user M, and the pair of left and right shoulder belt portions 40 may be mounted in a cross-hung manner.

  Further, in the baby carrier 1 of the above-described embodiment, the positioning base 30 uses a pair of female side 33a and male side 33b of the sliding fastener 33 as a fixing means for fixing the folded state. Although the length adjustment by folding the height adjusting portion 32 is possible, when the present invention is implemented, the number of sliding fasteners 33 can be increased and the folding length can be selected in stages. It is. The range of selection for adjusting the height position of the buttocks of the infant B is also increased by adjusting the number of folded sheets.

The means for fixing the fold is not limited to the sliding fastener 33, and may be a snap, a button and loop, a hook and ring, an adhesive cloth, or the like, or may be attached by attaching a separate adjuster or the like. As long as a member (part) that serves as a fixing means is fixed to the positioning pedestal 30, it is easy to manage without losing it. Also good.
Furthermore, when implementing this invention, such a slide type fastener 33 grade | etc., Can also be attached to the infant B side in the positioning base part 30. FIG.

In addition, in the baby carrier 1 of the present embodiment, the auxiliary holding part 20 and the connection part 21 can increase the effect of preventing the infant B from falling, and infants and infants can be handled even if they are not skilled in handling a baby or a piggyback. The arrangement position of B becomes easy to understand.
Here, in the baby carrier 1 according to the above-described embodiment, as a form for stably holding the torso of the infant B so as not to fall sideways, auxiliary holding is performed by connecting engagement of the connection plug 23 and the connection receiver 24. A connecting portion 21 having a predetermined length is formed to connect the left and right side portions on the free end side of the portion 20 and the left and right sides in the vicinity of the boundary between the backrest portion 12 and the abutment portion 13 of the main body portion 10. Since the auxiliary support portion 20 is separable, the engaging operation of the slide fastener 33 can be facilitated. However, when the present invention is carried out, the main body portion 10 and the auxiliary support portion 20 cannot be separated, and the infant B It is good also as a structure which forms the opening for legs.

The present invention relates to a baby carrier (childcare band) that assists and carries an infant when holding or carrying it, and in particular, the height position (depth position) of an infant's buttocks can be adjusted. Is about a baby carrier.

As a baby carrier that can be used for a long time without limiting the age of the infant to be held, according to the growth of the infant, by switching the user's wearing method from the horizontal holding of the infant to the vertical holding form, Although it has been known that it can be used for a long time from the neonatal period before sitting at the neck to 2 to 3 years old, recently a baby carrier corresponding to vertical holding from the neonatal period before sitting at the neck has also been proposed. ing. However, even in a specific form of holding in a vertical manner, the holding state of a stable and comfortable holding comfort with little burden on the infant changes according to the age, size, and growth of the infant. In addition, there are individual differences in individual body shapes of infants, and the optimum holding position with less burden on users such as infants and parents who hold infants differs depending on how to hold them. In particular, in infants before sitting on their necks, the ligaments that connect the muscles and joints are undeveloped and the joints of the crotch and knees are soft.

Here, in Patent Document 1 and Patent Document 2, a backrest part, a crotch pad part, and a front pad part are configured to be continuous, the crotch pad part is bent and formed in a side U shape, By connecting the both sides and both side surfaces of the front padding portion using a desired cloth or the like, a lullaby body formed in a bag shape or a cylindrical shape is constructed, and a predetermined length is provided from both sides of the upper end portion of the lullaby body. Now, the shoulder strap is stretched, and the tip portion thereof is configured to be locked at an appropriate portion of the waistband formed at the lower end portion of the lullaby body. A baby carrier constructed so that both ends of an auxiliary band for seat height adjustment are attached so as to pass between the inner side and the inner side of the front contact part, and at least one end part of the auxiliary band can be detachably locked by a locking tool. Is disclosed. As described in Patent Document 1 and Patent Document 2, according to such a baby carrier, a comfortable sitting height and a feeling of use that are the same as those of an infant with a standard body shape can be obtained even with an infant whose main body is smaller than the standard body shape that is planned. Is going to be able to get

Further, Patent Document 3 discloses that a back portion, a crotch portion, a front portion and the like are made continuous, and both sides of the back portion and both sides of the front portion are connected to form a cylinder (bag shape). The size of the crotch part (size formed by the crotch part) can be freely changed by interposing a seat height adjustment belt between the crotch part and the front part in the formed baby limp body. Thus, a lullaby that can freely adjust the sitting height is disclosed.

Furthermore, in the baby carrier disclosed in Patent Document 4, the size and length of the seating portion are adjusted by providing an elongated tongue piece on the seating portion of the infant through the lower coupling device and changing the length of the tongue piece. The baby carrier size can be adjusted according to the height of the child.

However, in the baby carriers described in Patent Document 1 and Patent Document 2, at least one end of the auxiliary seat for seat height adjustment attached so as to pass inside the back rest and the crotch rest is at the back rest, the crotch rest. The auxiliary belt and the main body are connected to each other because it is configured so that it can be detachably locked with a velvet fastener, a metal fitting, a belt, or the like with respect to the main body formed continuously with the front portion and the front portion. There was a concern about durability due to the load being easily applied to the locking portion. In particular, it is difficult to obtain a high connection strength at the connecting portion between the auxiliary belt and the main body portion with the velvet type fasteners described in Patent Literature 1 and Patent Literature 2 or the fasteners using metal fittings and belts. As a result of vibration caused by walking, the auxiliary belt rocks and the posture of the infant seated on the auxiliary belt tends to become unstable. Furthermore, even if the locking tool for making the auxiliary belt detachable is covered with the lid piece, there is a risk of giving the infant an uncomfortable feeling such as unevenness or discomfort.
In Patent Document 1 and Patent Document 2, there is no pursuit for an infant's open leg posture, and the technical idea of maintaining an open leg posture that does not impose a burden according to the age, size, and growth of the infant. There is no disclosure or suggestion.

In addition, the techniques described in Patent Document 3 and Patent Document 4 enable adjustment of the length of the main body part itself that constitutes the backrest part, the crotch part, the front part, and the like. The area (size) of the part applied to the infant's body is changed by the adjustment. Therefore, the design freedom of the main body is restricted, for example, when trying to set the width size so that it can be held in an open leg posture that does not place a burden on infants at a low age, when the infant becomes large, The area (size) necessary to sufficiently cover the enlarged infant's buttocks cannot be secured, the burden on the infant is increased, and a stable holding state cannot be obtained.

Therefore, it is possible to adjust the holding position of the infant and to maintain an open leg posture that does not impose a burden according to the infant's age, size, and growth, and the age before the neck is low. An object of the present invention is to provide a baby carrier that can be stably held with little burden even on infants.

The baby carrier of the invention of claim 1 is attached to the user by a pair of left and right shoulder belt portions, and is applied to the infant's body to support the infant in a wide area, and one end is the lower end of the body portion. An auxiliary holding portion that is connected to the body and is applied to the infant's body on the opposite side of the main body portion, and the main body portion and the auxiliary holding portion that are integrally and continuously between the main body portion and the auxiliary holding portion. And a positioning pedestal for positioning the sinking depth of the buttocks of the infant.

  The main body is applied to the infant's back when holding the infant so that the abdomen of the infant's body faces a parent or other user holding the infant, such as a face-to-face hug or a forward-facing piggyback. And the head and neck as appropriate to support and protect the infant's body over a wide area.

The auxiliary holding portion is disposed closer to the user holding the infant than the main body portion and is connected to the lower end portion of the main body portion, and a free end thereof extends upward, and the main body portion is applied. It is applied to the infant's body on the opposite side of the face. In other words, when holding an infant so that the infant's body's ventral side faces a parent or other user holding the infant, such as a face-to-face hug or a forward-facing piggyback, it is applied to the infant's body's ventral side (reverse side). Is. Usually, it is applied to the infant's body's ventral side (anti-dorsal side) with a smaller area than the main body, and one end connected to the lower end of the main body is in the left-right direction (horizontal direction) of the lower end of the main body. The width is narrower than the width.
The main body part and the auxiliary holding part are arranged such that the auxiliary holding part is arranged closer to the user side and the main body part is arranged farther from the user side.

  The shoulder belt portion is hung on the user's shoulders when holding or carrying an infant, and the main body portion and / or the auxiliary member is provided at a distance sufficient to turn the shoulder and back of the user. It is connected to the left and right sides of the holding part.

The positioning pedestal portion is integrally and continuously passed from the main body portion and the auxiliary holding portion between the main body portion and the auxiliary holding portion on the opposite sides of the main body portion and the auxiliary holding portion. The length can be freely adjusted by folding in the direction, and the sinking depth of the buttocks of the infant is positioned by adjusting the length.
Here, the length adjustment is performed by fixing the folded state by engaging engagement means formed integrally with the positioning pedestal, for example, fasteners, snaps, buttons and loops, hooks and rings, and adhesive cloths. The length of the pedestal part can be shortened and the length of the positioning pedestal part can be adjusted in a form in which the fold is unfolded by releasing the engagement, or the folded state can be fixed by attaching a separate adjuster The length may be shortened and the length may be adjusted in a form in which the fold is unfolded by removing an adjuster or the like.

Preferably, the positioning base portion is connected to the auxiliary holding portion so that a sinking lateral width of the buttocks of the infant when the length between the main body portion and the auxiliary holding portion is shortened by folding in the length direction. The width of the lower end of the main body is 5/10 to 9/10, more preferably 3/5 to 4/5.

Here, the sinking lateral width of the buttocks of the infant when the length between the main body portion and the auxiliary holding portion is shortened passes between the main body portion and the auxiliary holding portion by folding in the length direction. In the positioning pedestal portion whose length is shortened, it means the width of the lowermost part where the infant's buttocks are landed, that is, the position where the infant's buttocks is positioned by receiving the sink of the infant's buttocks.
And, when the length between the main body part and the auxiliary holding part is shortened, the sinking lateral width of the buttocks of the infant is within the range of 5/10 to 9/10 of the lateral width of the lower end part of the main body part. Preferably, the range of 3/5 to 4/5 is set so as not to apply a load to the infant's body shape, particularly the soft hip joint, even if the target is a younger infant before the neck It is. In addition, the lower end part of the said main-body part is a connection location with the lower end part of the said auxiliary | assistant holding | maintenance part.

By reducing the length between the main body portion and the auxiliary holding portion in the positioning pedestal portion, the depth between the main body portion and the auxiliary holding portion is reduced to both the main body portion and the auxiliary holding portion. The baby's buttocks are received by the positioning pedestal with a shorter length between the main body part and the auxiliary holding part at this time, from the closed bottom end to which is connected. If the width of the sinking is a width that is the same as the lower end of the main body that is set to a reasonably wide dimension that can cover the buttocks surface even for a large infant that has grown up, If the infant is a younger infant, the leg of the infant B cannot be lowered below the positioning base unless the crotch width is greatly increased. That is, infants are required to open a large crotch width.
Therefore, the lateral width of the positioning part that is received by the positioning pedestal portion when the length between the main body portion and the auxiliary holding portion is shortened and is reached by the infant's buttocks is determined by the lower end portion of the main body portion. The width is 5/10 to 9/10, more preferably 3/5 to 4/5. The leg posture is not overwhelmed.

Here, when the length between the main body portion of the positioning pedestal portion and the auxiliary holding portion is shortened, the sinking lateral width of the buttocks of the infant is less than 5/10 of the lateral width of the lower end portion of the main body portion. , The hips and buttocks of the infant may be compressed. On the other hand, when the width of the lower end of the main body exceeds 9/10, the crotch width is excessive for younger infants before sitting on the neck. May be demanding, and will impose a burden on young infants who are underdeveloped.
When the length between the main body part of the positioning base part and the auxiliary holding part is shortened, the sinking lateral width of the buttocks of the infant is 5/10 to 9/10 of the lateral width of the lower end part of the main body part. Within the range, more preferably within the range of 3/5 to 4/5, even if the infant of low age before sitting in the neck is intended to be held, the positioning pedestal sunk the infant's buttocks Infants too widen the crotch width from the lower position of the positioning pedestal to the closed lower end where both the auxiliary holding part and the main body are connected by the depth being raised to the upper part. The leg can be accommodated without any problems, and the hip joint and the buttocks are not compressed, and the infant's leg posture is reduced.

  Preferably, the auxiliary holding portion has a lateral width between the main body portion and the auxiliary holding portion at the maximum from the connection position with the lower end portion of the main body portion to a height position of 15 cm. It is set to 1.4 times or less of the sinking lateral width of the buttocks of the infant when the length is shortened.

From the connecting position of the auxiliary holding part to the lower end part of the main body part to the height position (length position) of 15 cm is the positioning when the length between the main body part and the auxiliary holding part is shortened. The lower part from the knees of both legs of the infant whose buttock is received by the pedestal part is a part that is extended from the left and right sides of the auxiliary holding part. Usually, assuming the body shape of a young infant before sitting on the neck, the length between the main body part of the positioning pedestal part and the auxiliary holding part is shortened to increase the sinking depth of the infant's buttocks upward (high position) ) Is set to 5 cm to 10 cm at the maximum from the lower end of the main body part connected to the auxiliary holding part even if considering the deflection due to the weight of the infant, etc. In the posture, the lower part is lower than the knees of both legs of an infant with a low age that opens in an M shape that is held at a high position in the range from the connection position with the lower end of the main body part to a height position of 15 cm. Will be served from both sides.

  Here, when the buttocks of the infant are held at a high position, the lateral widths of the left and right sides of the auxiliary holding part that are lower than the knees of both legs of the infant are the length between the main body part and the auxiliary holding part. When the width of the lower part of the infant's buttocks exceeds 1.4 times the width when the length is shortened, the infant's buttocks are positioned at a positioning portion for receiving the infant's buttocks with the width of the lower end of the main body being a predetermined narrow width. When this is done, the movement of the leg of the infant is liable to be restrained due to the wide dimensions of the auxiliary holding part, and the freedom of movement of the leg is lost. Further, because of the cramped feeling and inconvenience, the infant may excessively widen the crotch width trying to get out the legs from both sides of the auxiliary holding part. In particular, when the movement of the leg of the infant is restricted, the burden on the infant with a young age who is not yet well-developed is large, and the motor function of the infant may be hindered.

Therefore, in the auxiliary holding portion, the lateral width on both the left and right sides from the connection position with the lower end portion of the main body portion to the height position of 15 cm is set to the maximum length between the main body portion and the auxiliary holding portion. By setting it to 1.4 times or less the sinking width of the buttocks of the infant when shortened, the infant's leg movement is not limited even when targeting a younger infant before sitting down the neck. It is possible to prevent the crotch width from becoming too wide. Therefore, there is no fear of inhibiting the infant's motor function, and the load on the infant's body shape can be reduced.
To the height position of 15 cm, it is necessary to set a predetermined lateral width at a height of at least 15 cm, but the range of the predetermined lateral width dimension may be 15 cm or more.

In the baby carrier according to the first aspect of the present invention, when the positioning base portion is folded in the length direction to shorten the length between the main body portion and the auxiliary holding portion, the folded portion is the sinking of the buttocks of the infant. It becomes the positioning part which receives. Preferably, the folded portion is selectively set as a positioning portion, and the thickness of the positioning portion that receives the sinking of the buttocks of the infant can be selected.

The baby carrier according to the first aspect of the present invention further includes a waist belt portion that is connected to the lower end portion of the main body portion and the auxiliary holding portion and is worn around the waist of the user.
The waist belt part is attached to a user's waist when holding or carrying a baby, positioning the main body part that supports the baby, and supporting the weight of the baby. It is arranged so as to draw a substantially inverted T shape with respect to the main body part and the auxiliary holding part, and is attached around the waist of the user by a connecting tool such as a buckle disposed at the end in the horizontal length direction. , Removable. The connection of the waist belt part to the main body part and the auxiliary holding part may be sewing, or may be a structure that can be attached and detached by an engaging means or the like.
The up, down, left, and right directions described above indicate the directionality in a vertical holding state in which an infant is held or carried.

In the baby carrier according to the second aspect of the present invention, in the portion of the main body portion which is applied to the buttocks of the infant's body, the right and left side portions can be bent toward the infant side (inward), thereby allowing the infant to The space to be accommodated has a depth.

  According to the baby carrier of the first aspect of the present invention, the main body portion is disposed between the main body portion applied to the infant body and the auxiliary holding portion applied to the infant body on the opposite side of the main body portion. And a positioning pedestal portion formed integrally and continuously from the auxiliary holding portion is disposed and arranged, and the positioning pedestal portion is adjusted in a length direction so that the auxiliary holding portion of the main body portion is adjusted. It is possible to freely adjust the depth between the two, and the sinking depth of the buttocks of the infant is positioned. Therefore, the positioning base part disposed between the main body part and the auxiliary holding part receives the buttocks of the infant accommodated between the main body part and the auxiliary holding part, but the main body is folded by folding the positioning base part. If the length that passes between the main part and the auxiliary holding part is shortened, the sinking depth of the infant accommodated between the main part and the auxiliary holding part increases, and the folding of the positioning pedestal part is unfolded to expand the main part and the auxiliary holding part. If the length passing between the parts is increased, the sinking depth of the infant accommodated between the main body part and the auxiliary holding part is lowered, and the adjustment of the length passing between the main body part and the auxiliary holding part by the positioning pedestal part is performed. The height position of the infant to be held can be adjusted.

Therefore, even for young infants with small bodies, the length passing between the main body part of the positioning base part and the auxiliary holding part is shortened by folding in the length direction, so that the lower end part of the main body part and the lower end part of the auxiliary holding part Since the infant can be held at a position higher than the connection position, the infant's head position protects the infant without sinking or being buried between the main body and the auxiliary holder. Arranged at an appropriate position of the main body, the burden on the infant can be reduced and comfortable holding is possible. Also, when the infant grows up and the body grows large, the folding is unfolded, the length passing between the main body part of the positioning base part and the auxiliary holding part is lengthened, and the lower end part of the main body part and the auxiliary holding part are held. The infant is held at a low position on the connection side of the lower end of the part, and the infant's body is protected at an appropriate position on the main body part to enable comfortable holding. And the height position of the infant can be adjusted to a comfortable holding position for the user.
According to the age, size, and growth of the infant to be held in this way, the holding height position of the infant is adjusted to enable holding with less burden on the infant and the user.

  In addition, since the positioning pedestal portion raises the sinking depth of the buttocks of the infant to the upper level, the opening width of the crotch width of the infant is not affected by the width of the lower end portion of the main body portion, and the positioning pedestal Since the infant can fit the leg into the space from the lower part of the part to the closed lower end where both the auxiliary holding part and the main body part are connected, the hip joint is opened for younger infants. It is possible to prevent overshoot.

  And since the positioning pedestal for positioning the depth of the buttocks of the infant is formed integrally and continuously from the main body and the auxiliary holding part, the connection strength is stable without any positional deviation. In addition, the positioning pedestal portion is not detached from the main body portion and the auxiliary holding portion due to the weight of the infant, and the reliability is high. In addition, even when the infant's buttocks are received by the positioning pedestal when the length between the main body part and the auxiliary holding part is shortened, the swinging is small and the center of gravity of the infant's buttocks is easy to stabilize, and the posture is stable. It can reduce the burden on infants who are not stable and have a low age before sitting.

  In this way, it is possible to adjust the holding position of the infant and to maintain an open leg posture that does not impose a burden according to the age, size, and growth of the infant. Infants and children can be held stably with little burden.

In particular, in the positioning pedestal portion, when the length between the main body portion and the auxiliary holding portion is shortened, the sinking lateral width of the buttocks of the infant is 5 / 10-9 of the lateral width of the lower end portion of the main body portion. / 10, more preferably, by forming a narrow width within the range of 3/5 to 4/5, the infant's crotch width is more than necessary even for younger infants before sitting in the neck. It is possible to hold the leg with a natural leg posture with an M-shaped leg without opening the hip joint excessively. And since the lower end portion of the main body portion is wider than the sinking horizontal width of the buttocks of the infant when the length between the main body portion and the auxiliary holding portion is shortened, the positioning base portion is folded and the main body is expanded. Even when the infant's buttocks are received by the positioning pedestal that extends between the head and the auxiliary holding part, the infant's buttocks are widely covered by the appropriate wide dimensions at the bottom of the main body so that the legs are in an open leg position. Stable holding is possible without imposing a burden.
In addition, the auxiliary holding part has a width between the main body part and the auxiliary holding part at the maximum from the connection position with the lower end part of the main body part to the height position of 15 cm. When the length is shorter than 1.4 times the sinking lateral width of the buttocks of the infant, it is possible to hold the leg in an open leg posture with less burden without restraining the movement of the leg.

According to a baby carrier according to the invention of claim 1, when folded the positioning pedestal lengthwise, since the positioning part for receiving the the folded portions buttocks of sinking of the infant, folded with its A sense of stability is increased by increasing the bulk of the portion. Moreover, the selection depth of the folding position of the infant can be adjusted by selecting the folding, and the selection range of the position of the holding height of the infant can be widened.

According to a baby carrier according to the invention of claim 1, further, since having a waist belt part of the said body portion is connected to the lower end portion of the auxiliary holding portion is mounted around the waist of the user, infants Even if the baby grows and becomes heavy, the weight of the infant is distributed over the shoulder, back and waist, so that even a user who is stiff can reduce the load on the shoulder.

According to the baby carrier of the second aspect of the present invention, there is a space in which the infant is accommodated by a shape in which the left and right sides of the portion of the main body portion applied to the buttocks of the infant can be bent toward the infant side. Since a three-dimensional space with a depth can be formed, it is difficult to restrain the movement of an infant at a low age especially in an M shape. Therefore, in addition to the effect of the first aspect, it is possible to hold the infant with less burden on the infant at a low age.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Note that, in the embodiments, the same symbols and the same reference numerals are functional portions common to those embodiments, and thus detailed description thereof is omitted here.

  The baby carrier 1 according to the present embodiment includes a main body 10 that is applied to the body of the infant B on the side opposite to the user M holding the infant B, a lower body of the main body 10, and the main body 10 side. The auxiliary holding part 20 applied to the body of the infant B on the opposite side, one end in the length direction is connected to the infant B side (inner surface side) of the main body part 10, and the other end is the infant B side of the auxiliary holding part 20 The positioning pedestal 30 connected to (inner side) and passed between the main body 10 and the auxiliary holding part 20 and the auxiliary holding part 20 is passed in the vertical direction and hung on the shoulder of the user M. A pair of left and right shoulder belt portions 40, connected to the lower portions of the main body portion 10 and the auxiliary holding portion 20, are arranged in a direction perpendicular to the length direction of the main body portion 10 and the auxiliary holding portion 20, and And a waist belt portion 50 attached around the waist.

The main body 10 applied to the body of the infant B on the opposite side of the user M holding the infant B holds the infant B on the ventral side of the body of the infant B like a face-to-face holding or a forward facing piggyback. It is applied to the back side of the body of the infant B when the infant B is held so as to face the user M such as a parent.
The main body portion 10 of the present embodiment is a substantially semi-elliptical head support portion 11 that is mainly applied to the head of the baby B and receives the head mainly when the baby B is held with a face-to-face hug or a forward-facing piggyback. And a back support part 12 which is applied from the head side of the infant B to the back and waist and mainly receives the back part, and a support part 13 which is applied from the back side of the infant B to the buttocks and mainly receives the buttocks part. Are integrally formed. The main body 10 is provided with a predetermined softness by disposing a cushion material (elastic material) or a known core material having flexibility and some elasticity between exterior fabrics made of a front fabric and a back fabric. Property, flexibility, elasticity, buffering property and the like.

As for the exterior fabric of the main body 10, for example, by using a fabric having air permeability for at least a part or all of the surface applied to the body of the infant B, the air permeability of one surface side of the infant B body is improved. In addition, stuffiness can be prevented.
Examples of the fabric having air permeability include, for example, a mesh (net) fabric having a mesh / net pattern structure with a predetermined opening, a coarse fabric with a slightly rough texture, and a mesh fabric between the front and back surfaces. A three-dimensional knitted fabric (double raschel) having a specific thickness obtained by weaving connecting yarns forming an air layer having a specific thickness is used. By using such a fabric having air permeability, air permeability can be secured and moisture and heat can be dissipated. Furthermore, by providing the fabric with a mesh structure or providing a plurality of ventilation holes in the fabric, flexibility and stretchability are increased, and the fit and familiarity with the body shape and movement of the infant B and the user M are improved. Hygroscopicity can also be improved by using a material such as a cotton material with high water absorption for the exterior fabric.

  In particular, according to the three-dimensional knitted fabric (double raschel), the air layer formed by the connecting yarn woven between the front and back mesh fabrics also accommodates moisture such as sweat of infants B and users M. In addition, since the movement of the user M and the movement of the infant B become the volume change of the air layer, the air in the air layer is discharged and supplied. It can quickly absorb the sweat perspired from and can effectively release moisture and heat. Of course, because the mesh fabric and air layer on the front and back sides are excellent in air permeability and water permeability, moisture can be dried quickly. Furthermore, the air layer formed by the connecting yarns has some elasticity, cushioning properties, etc., and even if the infant B moves, the following change in the air layer does not cause a sense of incongruity, and the infant B's body shape is also good. . In addition, since the convection is not generated in the air layer by the connecting yarn woven between the mesh fabrics on the front and back sides, the heat insulating effect is high and the volume is large, so that the heat insulating action can be maintained for a long time.

  This three-dimensional knitted fabric (double raschel) is manufactured by a woven fabric manufacturing machine such as a double raschel machine or tricot machine. The product is "Fusion (trade name)" by Asahi Kasei Co., Ltd. and "Air Queen (trademark)" by Teijin Kosan Co., Ltd. Name) ”etc., and detailed explanation is omitted here.

It is to be noted that such a breathable fabric can reduce dampness and the like by being used at least in a position corresponding to the body of the infant B, but is applied to both surfaces of the main body 10, that is, the body of the infant B. By using a fabric having air permeability on both the front surface and the opposite surface, air permeability in the thickness direction is increased, and moisture and heat can be released more effectively. Moreover, it is good also as a structure which can adjust ventilation | gas_flowing quantity by the 2 layer structure which made the cloth | batter which has air permeability freely coatable with the cloth | airs without air permeability.
Of course, when carrying out the present invention, a non-breathable fabric may be used for the entire exterior fabric.

As a cushioning material put between the outer fabric made of the front fabric and the back fabric of the main body 10, for example, commercially available urethane, the trade name “Breath Air (registered trademark)” from Toyobo Co., Ltd., and “C” from Sea Engineering Co., Ltd. -CORE ", a three-dimensional network structure and the like sold under the trade name" Airweave (registered trademark) "by Airweve, Inc. are used.
In particular, a continuous linear body made of resin is irregularly meandering and intertwined, and is adhered to everywhere in a meandering state, and a space between the continuous linear bodies is continuously formed with a predetermined thickness. According to the net-like structure, it is lighter and more breathable than urethane, and can be less sanitary and hygienic. Further, according to the three-dimensional network structure 100 in which the continuous filaments are entangled three-dimensionally and have continuous voids in this way, the pressure receiving area is widened and the pressure applied to the infant B is easily dispersed. The burden on the body can be reduced.
Furthermore, hard urethane or a three-dimensional network structure can be used as the core material.

When such a cushioning material and a core material are provided in the main body 10, the shock to the infant B's body is alleviated even when holding the infant B who is young, especially before the neck sitting, whose posture is unstable. It is possible to obtain a high holding stability with little burden on the infant B and comfortable to hold.
In addition, use of a cushion material and a core material may be used only for a specific part, and it is also possible to use it without distinguishing both a cushion material and a core material. For example, the head support part 11 and the back support part 12 have a cushioning property and are formed of a hard material, so that the head, back, and waist of the infant B can be firmly supported, and the body can be glazed. And prevent backward tilting and warping. By forming the buttocks 13 with a cushioning and soft material, the buttocks of the infant B can be easily lowered, the center of gravity of the infant B can be stabilized, and the holding stability can be enhanced. Such a cushioning material or core material may be attached and detached.

  In the present embodiment, the cushion material and the core material placed between the outer fabric and the outer fabric of the front fabric and the back fabric are not made continuous at the boundary between the head support portion 11 and the back support portion 12, or the cushion material or Even if the core material is continuous, the front and back fabrics are sewn, or the cushion material and the core material are formed so as to be foldable. The head rest part 11 can be bent with respect to the surface of the back rest part 12. Thereby, although the back part 12 supports the back part of the infant B from the waist stably, the head part 11 is easily inclined with respect to the surface of the back part 12 according to the weight of the head of the infant B. (It is easy to bend) and the head and neck of the infant B can be protected so as not to overload the head and neck of the infant B. Furthermore, according to the growth and holding form of the infant B, the field of the infant B is widened by using the head support part 11 by bending it to the opposite side of the infant B side with respect to the surface of the back support part 12. Can do.

  Moreover, in the baby carrier 1 of the present embodiment, a substantially triangular shape formed of a cushioning material on the side (inner surface side) where the infant B at the boundary between the head support part 11 and the back support part 12 is disposed. The connecting portion 14 protrudes from the surfaces of the head rest portion 11 and the back rest portion 12, and the connecting portion 14 supports the tilt of the head of the infant B in the left-right direction, prevents glare and prevents the infant B from moving. The burden on the head and neck can be reduced. In particular, the head and neck of the infant B can be protected also by the cushioning property of the connecting portion 14. Furthermore, for a younger infant B who is held at a high position and the head support 11 and the back support 12 are applied to appropriate positions, the connecting portion 14 is disposed above the torso of the infant B, It has the effect of blocking light and sound, and can also be expected to promote comfortable sleep.

  The head support 11 is provided with a pocket-shaped storage portion having a predetermined storage volume (not shown), and is a surface on the opposite side of the main body 10 shown in FIG. A slide fastener 15 (a hook, a button, an adhesive cloth, etc.) for opening and closing a storage portion (not shown) on the design surface side when the user M is wearing the baby carrier 1 may be used. ), And can accommodate a head hood (not shown) having a predetermined area covering the head of the infant M, items such as a cooling agent and a towel. For example, the head hood (not shown) has one end fixed to the storage portion by sewing or the like, and the other end connected to the shoulder belt portion 40 (for example, a buckle, hook, eggplant, carabiner, D lock, quick catch, The head of the infant B is covered and supported from the back of the head, and the head of the infant B falls backwards even when the infant B is sleeping. It functions as a cover that hides breastfeeding when the baby B is fed while being held while the baby carrier 1 is worn, or the like is prevented.

  And, by providing such a storage unit (not shown), when the head hood is not used, it can be folded and rolled in and inserted through the opening of the storage unit, and it can be stored inside, making the whole compact and designable In addition, the safety of the infant B can be improved, and the presence of the head hood and the like can be obscure by closing the opening of the storage portion with the fastener 15 or the like, and the belongings stored in the storage portion fall. There is nothing. However, when the present invention is implemented, the head hood may be wound and fixed with an adhesive cloth or the like without being provided with a storage portion, and may be configured to be held in an orderly manner, or the storage portion and the head hood may not be provided. .

  Further, in the abutment portion 13 of the present embodiment, a center portion 13A that receives the center side of the buttocks of the infant B and a pair of left and right end portions 13B that are located on both the left and right sides of the center portion 13A and that are near the thighs of the infant B It is composed of

In the baby carrier 1 according to the present embodiment, the center portion 13A and the pair of end portions 13B of the holding portion 13 are formed by draping, and the center portion 13A and the pair of end portions 13B are formed on the inner side ( A pair of sewing lines 13a curved in an arc shape toward the center side) are joined to each other, and an end portion 13B is formed to be foldable toward the infant B side with respect to the surface of the central portion 13A. Further, the lower end portion of the abutment portion 13 is curved in a substantially arcuate manner with a substantially straight sewing line 13b that contacts the upper end portion of the main body belt portion 51 with respect to a main body belt portion 51 of the waist belt portion 50 described later. They are integrally connected by a sewing line 13c (see FIGS. 6 and 8).
Thus, the formation of the three-dimensional accommodation space makes it difficult for the movement of the leg of the infant B when held at a high position, which will be described later, to be restrained, and also the position of the center of gravity of the buttocks of the infant B is easily stabilized.

  In other words, the end portions 13B on the left and right sides of the abutment portion 13 are brought closer to the infant side by draping, and the connection of the abutment portion 13 to the waist belt 50 is performed on the two sides of the sewing line 13b and the sewing line 13c. Therefore, since the depth is increased and the accommodation space can be afforded, the movement of the leg of the infant B can be played. Furthermore, the center of gravity of the buttocks of the infant B is easy to stabilize. Particularly, the outer shape of the central portion 13A joined to the end portion 13B by the sewing line 13a is a shape curved toward the central side, that is, a shape narrower on the central side than the upper and lower end portions. Is easy to drop, and the position shift of the buttocks hardly occurs. Therefore, the child B can be held in a comfortable posture with less burden, and the holding stability is increased. That is, the position of the center of gravity is determined from the position of the buttocks of the infant B, and there is no difficulty in holding the infant B.

  In addition, the center portion 13A and the end portion 13B in the holding portion 13 can be connected by preventing the cushion material or the like placed between the outer fabric and the outer fabric of the front fabric and the back fabric from being continued, or even if the cushion material or the like is continued. By sewing the front fabric and the back fabric, or by forming the cushion material itself so as to be foldable, the center portion 13A and the end portion 13B are distinguished from each other, and the end portion with respect to the surface of the center portion 13A. 13B is formed in the infant B side so that bending is possible.

  In the case of carrying out the present invention, in the central portion of the heeling portion 13, it is formed by draping, or by changing the thickness of the cushioning material to be put into the outer fabric of the front fabric and the back fabric, etc. Infant B can also be formed by forming a recess so that the buttocks can fall freely, or by changing the cushioning properties and flexibility of the cushioning material placed in the outer fabric of the front fabric and the back fabric. It is possible to stabilize the drop of the buttocks and improve the holding stability.

  In addition, for the infant B held in an open leg state, the thighs are easily loaded by the outer edges of the right and left sides of the butting part 13 being in contact with each other. In the end portion 13B, the cushioning property of the infant B can be reduced by increasing the cushioning property compared to the central portion A by disposing a cushioning material having a high cushioning property.

Furthermore, in the baby carrier 1 of the present embodiment, the lateral width on the upper side of the abutment portion 13 is gradually narrowed toward the backrest portion 12 side. That is, on the upper side of the abutment portion 13, the outer edges of the left and right end portions B are inclined inward (center side) upward.
Thereby, even when holding the buttocks of the infant B at a low position as will be described later, the lower part of the buttocks 13 receives the buttocks by a wide dimension that covers the buttocks of the infant B and stably supports the depression of the buttocks. However, the movement of the leg of the infant B becomes difficult to be restrained by being narrow toward the top. Therefore, holding in a comfortable open leg posture is possible.

  In addition, although the butting part 13 of this Embodiment is formed in the area of the area which surrounds the buttocks of the infant B in the state of an open leg, the horizontal width of the lower end part is usually set in the range of 20 cm to 35 cm. More preferably, it is within the range of 23 cm to 30 cm, so that the width of the crotch of the infant B is unnecessarily widened to limit the movement of the leg corresponding to the body shape of the infant B in Japan (Japan). The burden on the body shape of the infant B in the leg state can be minimized. The width dimension here is a numerical value obtained by measuring the fabric length between the left and right edges on the outer surface side of the abutment portion 13 formed by draping.

  Moreover, in the baby carrier 1 of the present embodiment, the horizontal width in the horizontal direction is narrow at the boundary between the backrest portion 12 and the abutment portion 13 and the design is such that the abutment portion 13 widens downward from there. In particular, the buttocks 13 make it easy for the baby B to drop the buttocks. Moreover, in the back support part 12 and the back support part 13, by changing the characteristics such as cushioning and hardness, for example, by making the hardness of the back support part 13 soft compared to the back support part 12, The buttocks 13 of the infant B can be easily depressed in the hitting unit 13.

  For example, the vertical length of the backrest 12 and the heel rest 13 combined with each other corresponds to, for example, the length of the upper body of the average infant B from 4 to 12 months after sitting on the neck. 40 cm to 45 cm, and the width of the lateral width of the backrest 12 is 40 cm to 4 mm, for example, corresponding to the average back width of the infant B from 4 to 12 months after sitting on the neck. Set to 45 cm.

  And in the baby carrier 1 of this Embodiment, the main body part 10 in which the head support part 11, the back support part 12, and the support part 13 are integrally formed in this way is the lower end part on the side of the support part 13. The waist belt portion 50 is sewn by the above-described linear sewing line 13b and the arc-shaped sewing line 13c. The main body portion 10 and the waist belt portion 50 are disposed in a substantially inverted T shape as a whole, and are integrally connected to the waist belt portion 50 by sewing only the lower end of the main body portion 10 and the vicinity thereof. The main body 10 can be bent in a direction perpendicular to the surface direction of 50.

  The waist belt portion 50 is disposed in a direction substantially orthogonal to the length direction (vertical direction) of the main body portion 10 and the auxiliary holding portion 20 below the main body portion 10 and the auxiliary holding portion 20 described later. As a form in which the weight (the weight of the infant B) is distributed so that it can withstand the strength because it receives a lot of body weight, and it does not overload the body shape of the user M even if it is attached to the waist of the user M And a main body belt portion 51 that is integrated with the main body portion 10 and an auxiliary holding portion 20 that will be described later, and a fabric belt that has a wide belt and has a buckle with an adjuster disposed at both ends in the longitudinal direction of the main body belt portion 51. It comprises a pair of left and right length adjusters 52. The waist belt portion 50 can be fixed around the waist of the user M by the coupling engagement of the coupling insert 53 of the buckle with adjuster provided in the length adjusting unit 52 and the coupling receiver 54, and the coupling insertion By making the tool 53 and the connection receiver 54 connectable, the user 53 can freely attach and detach the waist of the user M.

  The main body belt portion 51 having a wide vertical width is made of a material having predetermined flexibility, flexibility, elasticity, buffering property, etc., and improves the familiarity of the user M around the waist and improves the fit. This reduces the burden on the user M. For example, the core material and the cushion material as described above are inserted between the outer fabric and the outer fabric of the front fabric and the back fabric. Thereby, the load applied to the waist of the user M is easily dispersed. In addition, in the main body belt portion 51, by using a fabric having air permeability as the exterior fabric, moisture such as stuffiness can be prevented and uncomfortable feeling can be reduced. Moreover, hygroscopicity improves also by forming the inner surface side which touches the user's M waist circumference with a cotton fabric etc. with water absorption.

  1 and 2, the overall shape of the main body belt portion 51 is such that the lower portion thereof is curved in an arc shape downward, and the vertical direction in the vertical direction is formed at the center side connected to the main body portion 10 and the auxiliary holding portion 20. The width is maximum, and the vertical width is gradually narrowed toward both ends in the length direction. The vertical width is in the range of 10 to 20 cm, and the force applied to the waist of the user M is effective. In this structure, the weight felt by the user M can be reduced.

  The pair of left and right length adjusting portions 52 provided at both ends of the main body belt portion 51 have a predetermined length so that the belt length necessary for the user M to be attached to the waist is determined. By having the adjuster function in the connection plug 53 and the connection receiver 54 made of male and female buckles with adjusters, it is possible to match the circumference of the waist of the user M. The adjuster may be an independent adjuster as long as the belt length can be adjusted, or may be an integrated adjuster.

In the present embodiment, the connecting plug 53 and the connecting receiver 54 for connecting the waist belt portion 50 in an annular shape and fixing it around the waist of the user M are constituted by a pair of male and female buckles. It is possible to attach and detach with one touch, the detaching operation is easy, and it is not detached unless it is manually disengaged, and the attachment is highly reliable and the mechanical strength is also high.
However, when implementing this invention, it is not limited to a buckle, and connecting tools, such as an eggplant, a carabiner, a spring hook, D lock, a quick catch, an elliptical ring, can be used, and any may be selected. Usually, those that can be easily connected and have high safety are used.

Furthermore, the auxiliary holding part 20 is sewn to the waist belt part 50 with the sewing line 13b with the main-body part 10. FIG.
The auxiliary holding portion 20 is disposed on the infant B side of the main body portion 10, and the lower end portion thereof is integrally attached to the waist belt portion 50 together with the main body portion 10. Otherwise, the auxiliary holding portion 20 is separable from the main body portion 10. It is applied to the body of the infant B on the side opposite to the main body 10 side. When the infant B is held with a face-to-face hug or a forward-facing piggyback, the infant B is applied to the opposite back side, that is, the crotch side or the abdomen side. Note that the relationship between the auxiliary holding portion 20 and the waist belt portion 50 is also generally arranged in a substantially inverted T shape, and is integrally connected to the waist belt portion 50 by sewing only the lower end of the auxiliary holding portion 20. The auxiliary holding part 20 can also be bent in a direction perpendicular to the surface direction of the part 50.

The auxiliary holding part 20 of the present embodiment has its lower end fixed together with the main body part 10 by sewing to the waist belt part 50, but is attached to the waist belt part 50 at one end (lower end part) on the fixing side. connection width W ₂ that is connected is narrower than the connection width W ₁ of the main body portion 10 and the waist belt part 50 is connected by stitching, inner than the connection width W ₁ of the main body portion 10 and the waist belt part 50 On the other hand, it is sewn to the waist belt portion 50 together with the main body portion 10 at the sewing line 13b, and has a substantially trapezoidal shape gradually widened toward the other end side of the free end extending upward.

For example, the auxiliary holding portion 20 is sewed to the waist belt portion 50 at the connection lateral width W ₂ (see FIG. 6) of one end (lower end portion) that is sewn to the waist belt portion 50 and connected to the lower end portion of the main body portion 10. and which is set within a range of 50% to 90% of the connection width W ₁ of the lower end portion of the main body portion 10, even if the infant B is held at a lower position, as described below, to compress the groin of the baby B And the movement of the leg of the infant B is difficult to be restricted.

In particular, in the auxiliary holding part 20 according to the present embodiment, the outer edges on both the left and right sides from which the legs of the infant B with the buttocks received by the positioning pedestal part 30 to be described later are projected from the upper free end side to the lower waist belt part 50. And the waist belt portion 50 with the lateral width being gradually narrowed downward (90 °) vertically toward the connection side to the main body 10 or with an inclination of more than 90 ° and 140 ° or less. It is connected to the lower end of the main body 10.
As a result, the leg movement of the infant B is prevented from being restrained even when the infant B with a low age before sitting on the neck is held at a high position, as will be described later. A natural posture that is less burdensome for younger infants B without spreading more than necessary, and an open leg posture of about 130 ° is ideal, but it leads to a form close to the natural open leg posture, The load on the body shape of the infant B in the leg state is minimized.

  As shown in FIGS. 6 and 8, the auxiliary holding portion 20 has a vertical length (vertical width dimension) that is approximately the same as the abutment portion 13 of the main body portion 10, and the infant B When the auxiliary holding portion 20 is disposed opposite to the holding portion 13 of the main body portion 10, the left and right ends of the holding portion 13 are smaller than the area of the holding portion 13. The holding part 13 is larger to the extent that the part 13B starts to protrude.

In the baby carrier 1 according to the present embodiment, the auxiliary holding part 20 is interposed between the user M and the infant B, and the user M and the infant B do not directly contact with each other. It is difficult to collect between the person M and the infant B. Therefore, it is difficult for the infant B and the user M to get stuffy, and discomfort can be reduced. Moreover, the auxiliary | assistant holding | maintenance part 20 intervenes between the user M and the infant B, and it can prevent the wrinkles produced by the body temperature of the infant B from entering the clothing of the user M.
Such an auxiliary holding part 20 is also formed of a material having predetermined flexibility and flexibility so that the body shape of the infant B is not excessively added. While the auxiliary holding part 20 is applied to the body of the infant B, the back side of the auxiliary holding part 20 touches the user M side. By improving the ventilation of the part and releasing moisture and heat, it is possible to prevent partial temperature rise and stuffiness, and to reduce discomfort due to heat and stuffiness. That is, by using a material having air permeability, moisture and heat such as stuffiness of the infant B and the user M can be released, and an abnormal heat retention state does not occur between the infant B and the user M.

  In the case of carrying out the present invention, as such a configuration of the auxiliary holding portion 20, for example, the entire auxiliary holding portion 20 is a connecting yarn that forms an air layer having a specific thickness between the front and back mesh fabrics. It is also possible to form it with a three-dimensional knitted fabric (double raschel) woven with woven fabric, or to have a structure in which the front or back surface is covered with an exterior fabric. Further, the auxiliary holding part 20 may be composed of only one or two or more exterior fabrics, preferably the entire auxiliary holding part 20, only with a breathable mesh-structured cloth that allows air to flow on the front and back. A cushioning material such as urethane or a three-dimensional network structure may be placed in an exterior fabric made of a front fabric and a back fabric.

  In particular, when a three-dimensional knitted fabric (double raschel) is used, the woven fabric body maintains a breathable air layer as a whole, and convection does not occur in the air layer due to the connecting yarn woven between the front and back meshes. Since the heat insulating effect is high and the volume is large, the heat insulating action can be maintained for a long time. In addition, it has a volume that can store moisture against the generation of moisture such as sweat, and the movement of the user M and the movement of the infant B become the volume change of the woven fabric body, and the woven fabric body is held. The high-temperature air and high-humidity air are discharged, and low-humidity and low-temperature air is introduced from the outside. In other words, moisture and heat are likely to escape. Therefore, an increase in moisture is prevented, and sweat sweated from the body of the user M or the body of the infant B is quickly absorbed by the woven fabric body, and heat and stuffiness are remarkably reduced. Therefore. Occurrence of sweat rash is prevented, and measures against sweating, heat and stuffiness, and sweat rash. And even when the infant B is held, the feeling of tingling and stickiness does not occur. Furthermore, even when the baby B is held, there is no sense of incongruity due to the following change of the woven fabric body.

  In addition, as a cushioning material to be put into the exterior fabric, even when a continuous linear body made of resin is irregularly meandering and intertwined, and a three-dimensional network structure that is adhered in a meandering state is disposed. It has a volume capable of accommodating moisture such as sweat of the infant B or the user M, and the space between the continuous striatum is continuous, and moisture and heat are less likely to be accumulated due to a high porosity. In particular, if the whole or part of the three-dimensional network structure is covered with a breathable fabric, fresh air is taken in, and the volume of the air layer changes due to the movement of the user M and the movement of the infant B. Therefore, high-temperature air and high-humidity air are discharged, and low-humidity and low-temperature air is introduced from the outside. Therefore, the heat and moisture of the body of the user M and the infant B can be released, the heat and stuffiness can be reduced, and the feeling of stickiness and stickiness when holding the infant B is reduced. Further, even when the baby B is held, there is no sense of incongruity due to the following change of the three-dimensional network structure.

  In the baby carrier 1 of the present embodiment, since the mechanical strength is mainly entrusted to the main body 10 that receives the infant B in a wide area and supports and protects the body of the infant B, the entire auxiliary holding part 20 is entrusted. However, the mechanical strength does not need to be as strong as that of the main body 10, but a part of the weight of the infant B is also applied to the auxiliary holding portion 20. In addition, since the auxiliary holding unit 20 has at least the outer surfaces of the front and back sides of the same configuration as the main body unit 10, the auxiliary holding unit 20 and the main body unit 10 have a sense of unity and look good. When implementing the above, a different configuration may be adopted.

  And in the baby carrier 1 of this Embodiment, the cloth of predetermined length which has the connection insertion tool 23 of the buckle with an adjuster in the front-end | tip via the connection cloth 25 in the right-and-left both ends by the side of the free end of the auxiliary | assistant holding | maintenance part 20. A pair of left and right connection adjusting portions 22 formed of a belt are attached, and a connection difference is formed near the boundary between the backrest portion 12 and the abutment portion 13 on the left and right sides of the outer surface side of the main body portion 10 (the opposite side to the infant B side). A connection receiver 24 of a buckle corresponding to the engagement of the insertion tool 23 is attached, and by the connection engagement of the connection insertion tool 23 and the connection reception tool 24, the left and right side parts on the free end side of the auxiliary holding part 20 A connecting portion having a predetermined length is formed to connect the backrest portion 12 of the main body portion 10 and the left and right sides in the vicinity of the boundary of the heel portion 13.

  Therefore, in the baby carrier 1 of the present embodiment, the auxiliary holding portion 20 sewn to the waist belt portion 50 together with the main body portion 10 on the infant B side (inner surface side) of the main body portion 10 is connected and adjusted on both right and left sides. The distance between the main body part 10 and the auxiliary holding part 20 by being connected to the main body part 10 by the connection part 21 having a predetermined length formed by the connection engagement of the part 22 and the connection plug 23 and the connection receiver 24 ( Distance) is fixed, and the infant B is positioned in a space formed between the main body 10, the auxiliary holding part 20 and the connection part 21. Thus, the infant B is accommodated between the main body part 10, the auxiliary holding part 20, and the connection part 21, and the main body part 10 is applied to the back side of the infant B in the face-to-face hug and the forward facing piggyback. The auxiliary holding part 20 is assigned to the abdominal side, and the infant B is held by the connecting part 21 so as not to fall sideways. In particular, the leg of the infant B is passed through the annular opening formed between the left and right side edges of the main body 10 and the left and right side edges of the auxiliary holding part 20 below the connection part 21. The situation where the infant B falls from the side of the head rest 11 of the main body 10 due to the bowing of the infant B due to the restriction of the accommodation space of the infant B or the user M's forward bending posture, etc. Can be prevented. Further, even when the position of the baby B is moved with respect to the user M by switching the holding and the piggyback, the infant B can be prevented from falling and the user M can easily switch the holding and the piggyback even if not skilled. And

  In particular, the length of the connection portion 21 can be adjusted by adjusting the length of the pair of connection adjustment portions 22 of a predetermined length by the adjuster function of the connection insert 23 of the buckle. Thus, the interval (distance) between the main body portion 10 and the auxiliary holding portion 20 can be freely adjusted. Thus, the optimal distance between the infant B and the user M can be adjusted with an appropriate close contact distance with the user M where the infant B does not feel cramped. Therefore, the infant B can be held in such a manner that the body position is stabilized with little shaking by the infant B, and a comfortable holding feeling with less burden on both can be obtained by the sense of unity between the user M and the infant B.

  In the present embodiment, since the connection insertion tool 23 and the connection receiver 24 are freely connectable, depending on the convenience of the user M, the connection insertion tool 23 and the connection receiver 24 can be connected and engaged. In the state where the main body part 10 and the auxiliary holding part 20 are connected by the connection part 21, the baby B can be taken in and out between the main body part 10 and the auxiliary holding part 20, and the connection plug 23 and the connection receiver Even when the free end side of the auxiliary holding part 20 is separated from the main body part 10 by releasing the connection engagement 24, the baby B can be put in and out between the main body part 10 and the auxiliary holding part 20.

  Furthermore, in the present embodiment, the adjuster can be adjusted even when the main body 10 and the auxiliary holding part 20 are connected by the connecting part 21 by the connecting engagement of the connecting plug 23 and the connecting receiver 24 by the buckle with the adjuster function. The distance between the two can be freely adjusted by the function, and the baby B is accommodated in the space formed between the main body 10, the auxiliary holding part 20 and the connecting part 21. However, in the case of carrying out the present invention, an adjuster function may be provided in both the connection plug 23 and the connection receiver 24, or either one of them may be adjusted. Or the adjuster function may be made independent. In addition, the means for connecting the main body 10 and the auxiliary holding part 20 is not limited to the engagement of the buckle, but as a coupling engagement using a coupling tool such as an eggplant, a carabiner, a spring hook, a D lock, a quick catch, or an elliptical ring. Alternatively, the connection may be made using a stretchable member such as a stretchable rubber band or rubber tape. For example, rubber that is elastically stretchable in the longitudinal direction and that is designed by wrapping a flat rubber having a width of about 3 cm to 10 cm with a cloth or the like that extends to such an extent that an infant B can be inserted between the main body 10 and the auxiliary holder 20. By sewing a band (rubber tape) between the side portions of the main body portion 10 and the auxiliary holding portion 20, the distance (distance) between the main body portion 10 and the auxiliary holding portion 20 can be freely adjusted by expansion and contraction thereof. In the connection using such an elastic member such as an elastic rubber band, rubber tape or the like, an engagement operation for connecting the main body 10 and the auxiliary holding part 20 is not required, and it is easy to use. On the other hand, the connection by engagement of a buckle or the like is highly durable.

  In the figure, the connection adjusting part 22 is attached to the auxiliary holding part 20 via the connection cloth 25 by sewing to the connection cloth 25 protruding from the left and right end parts on the free end side of the auxiliary holding part 20. . Further, the buckle connection receiver 24 is also attached to the main body 10 via a separate connection belt fabric 26 sewn on the main body 10.

The one pair of left and right shoulder belt portions 40 are firmly attached to the left and right of the upper end portion on the free end side of the auxiliary holding portion 20 by sewing, and the other end portions are upper portions on the free end side of the auxiliary holding portion 20. It is firmly attached to the left and right side parts of the sewing machine via a connecting fabric 25 by sewing. That is, the shoulder belt portion 40 of the present embodiment is passed in the vertical direction of the auxiliary holding portion 20. In addition, the upper and lower here should just be passed so that it may connect to two upper and lower places of the auxiliary | assistant holding | maintenance part 20, and it may pass so that the user's shoulder may be passed, and shows relative positional relationship. It does not specify the connection position to the auxiliary holding unit 20. In addition, it does not strictly follow the up and down direction, but shows the height.

  The pair of left and right shoulder belt portions 40 are directly or indirectly connected to the auxiliary holding portion 20 and the main body portion 10 to receive much of the weight of the infant B, so that the shoulder belt portion 40 can withstand the strength of the user M. As a form in which force (the weight of the infant B) is distributed so as not to overwhelm the user M's body shape even if it is mounted around, it is integrally connected to the upper end on the free end side of the auxiliary holding part 20 and wide in width. A shoulder portion 41 and an adjustment belt portion 42 attached to the other end of the shoulder portion 41 and connected to the left and right side portions of the upper portion of the auxiliary holding portion 20 on the free end side.

  Since the shoulder portion 41 is hung on the shoulder of the user M, the shoulder portion 41 is formed of a material having predetermined flexibility, flexibility, elasticity, shock absorbing property, etc., and improves the familiarity around the shoulder of the user M, The burden on the user M is reduced by improving the fit. For example, a flexible core material or cushion material is inserted between the outer fabric and the outer fabric of the back fabric, and the weight of the infant B on the shoulder or back of the user M Concentration can be prevented. In addition, also in the shoulder part 41, moisture such as stuffiness can be prevented and discomfort can be reduced by using a breathable fabric for the exterior fabric. Moreover, hygroscopicity improves also by forming the inner surface side which touches the circumference | surroundings of the user M with a cotton fabric etc. with water absorption.

  The adjustment belt portion 42 connected to one end portion of the shoulder portion 41 includes a belt portion 42a formed of a cloth belt having a predetermined length so that a belt length necessary for attaching the user M around the shoulder is determined, and a shoulder portion.

  Therefore, the length between the female side 33a and the male side 33b is closed by closing the pair of the female side 33a and the male side 33b of the slide-type fastener 33 that are separated by a predetermined distance in the length adjusting unit 32. The length of the positioning pedestal 30 that is fixed in the folded state and connects between the main body 10 and the auxiliary holder 20 is shortened. On the other hand, when the engagement of the pair of female side 33a and male side 33b of the sliding fastener 33 is released, the folding is unfolded, and the positioning pedestal portion 30 has the original length and the main body portion 10 and the auxiliary holding portion 20. Connect between.

  Thus, in the baby carrier 1 of the present embodiment, the positioning pedestal portion 30 passed between the main body portion 10 and the auxiliary holding portion 20 on the opposite side (inner surface side) of the main body portion 10 and the auxiliary holding portion 20 is provided. In this positioning pedestal portion 30, the pair of female sides 33 a and the male side 33 b of the slide type fastener 33 are attached with a predetermined distance apart, so that the pair of female sides 33 a of the slide type fastener 33 can be separated from each other. When the male side 33 b is not engaged, the main body 10 and the auxiliary holding unit 20 are connected by the original length of the positioning base 30. On the other hand, by engaging the pair of female side 33a and male side 33b of the sliding fastener 33, the length between the female side 33a and the male side 33b is fixed in a folded state. The length for connecting the auxiliary holding portions 20 is shortened by the distance between the pair of female side 33a and male side 33b of the sliding fastener 33.

  Thus, the engagement between the pair of female side 33a and male side 33b of the slide-type fastener 33 attached at a predetermined distance apart from each other in the length adjusting unit 32 causes a gap between the main body part 10 and the auxiliary holding part 20 of the positioning base part 30. The connection length can be shortened, and the length of connection between the main body portion 10 and the auxiliary holding portion 20 of the positioning pedestal portion 30 can be adjusted.

  Thus, when the infant B is disposed between the main body 10 and the auxiliary holding portion 20, a pair of female sides 33a of the sliding fastener 33 of the positioning base portion 30 that passes between the main body 10 and the auxiliary holding portion 20 is provided. In the state where the male side 33b is not engaged, the length of the positioning pedestal 30 disposed between the main body 10 and the auxiliary holding portion 20 is long. The infant B, which is housed between the main body 10 and the auxiliary holding part 20 and has the buttocks received by the positioning pedestal 30, has a deepened sinking depth. That is, the buttocks of the infant B are positioned at a low position.

  In the present embodiment, the overall length of the positioning pedestal portion 30 that is the sum of the length of the second abutment portion 31 and the length of the length adjustment portion 32 is the backrest portion 12 of the main body portion 10 and the abutment portion 13. From the position where the positioning pedestal portion 30 is connected in the vicinity of the boundary portion to the lower end of the main body portion 10 connected to the auxiliary holding portion 20 and the lower end of the auxiliary holding portion 20 connected to the lower end portion of the main body portion 10 It is formed more than the length dimension which combined the length to the place where the positioning base part 30 was connected. As a result, the main body portion 10 and the auxiliary holding portion 20 are connected by the original length of the positioning pedestal portion 30 in a state where the pair of the female side 33a and the male side 33b of the sliding fastener 33 are not engaged. The sinking depth of the buttocks of the infant B received by the positioning pedestal 30 is as close as possible to the depth formed by the main body 10 and the auxiliary holding part 20. That is, in a state where the pair of female side 33a and male side 33b of the sliding fastener 33 is not engaged, the positioning pedestal portion 30 is superposed along the length of the main body portion 10 and the auxiliary holding portion 20. Then, the buttocks of the infant B arrive on them.

  On the other hand, in the engagement state in which the pair of female sides 33a and the male side 33b of the sliding fastener 33 of the positioning base 30 passing between the main body 10 and the auxiliary holding unit 20 are closed together, a pair of female sides Since the length between 33a and the male side 33b is folded and the connection length of the positioning pedestal portion 30 connecting the main body portion 10 and the auxiliary holding portion 20 is shortened, the positioning pedestal portion 30 causes the main body portion to be shortened. 10 and the auxiliary holding part 20 is raised in depth, and the infant B, which is accommodated between the main body part 10 and the auxiliary holding part 20 and is received by the positioning pedestal 30, has a shallow sinking depth. Become. In other words, the buttocks of the infant B are positioned at a high position.

  Therefore, according to the baby carrier 1 of the present embodiment, when the infant B to be held is low in height, the slide of the positioning pedestal 30 disposed between the main body 10 and the auxiliary holder 20 is arranged. By engaging the pair of female side 33a and male side 33b of the type fastener 33 and shortening the connection length between the main body part 10 and the auxiliary holding part 20 in the positioning pedestal part 30, Since the sink is positioned at a high position, even if the infant B to be held is short, the head of the infant B does not become a low position in the positional relationship between the main body 10 and the infant B, and the head of the infant B is the head. The baby B is stably placed in a comfortable posture with less burden, without being placed in the body 11 and the body 20 and the auxiliary holder 20 so that the body of the baby B sinks.

  When the infant B to be held is tall, that is, when the infant B becomes large due to growth, the pair of female side 33a and male side 33b of the sliding fastener 33 is disengaged, By developing the connection length between the main body part 10 and the auxiliary holding part 20 to the original length in the positioning pedestal part 30, the sinking of the buttocks of the infant B is positioned at a low position. On the other hand, the head support part 11, the back support part 12, and the buttocks support part 13 of the main body part 10 are applied at appropriate positions, and the infant B is stably held in a comfortable posture with less burden.

  In particular, according to the baby carrier 1 of the present embodiment, the length adjusting portion 32 of the positioning pedestal portion 30 is disposed on the auxiliary holding portion 20 side, and a pair of female side 33a and male side 33b of the sliding fastener 33 is provided. While the length between the pair of female side 33a and male side 33b is folded in the engaged state, the folded portion 32a (FIG. 4) is folded down to the second holding portion 31 side and overlapped with the holding portion 31. It is designed to receive the buttocks of the infant B at the combined position 32A (see FIGS. 5, 6, 10, and 12). That is, in a state where the pair of female side 33a and male side 33b of the slide type fastener 33 are engaged to shorten the connection length between the main body portion 10 and the auxiliary holding portion 20 of the positioning base portion 30, A position 32A in which the folded portion 32a in which the length between the female side 33a and the male side 33b is folded is overlapped with the second abutment portion 31 is a positioning portion where the sinking of the buttocks of the infant B is received. .

And in this Embodiment, the positioning base part of the state which engaged the pair of female side 33a and male side 33b of the slide-type fastener 33, and shortened the connection length between the main-body part 10 and the auxiliary | assistant holding | maintenance part 20. In the positioning portion 32 where the buttocks of the infant B are received and positioned at 30, the lateral width W _{3 in the} left-right direction (horizontal direction) is set within the range of 10 cm to 20 cm, more preferably within the range of 15 cm to 20 cm. 5/10 or more, 9/10 or less, more preferably 3/5 or more of the lateral width W ₁ of the lower end of the main body 10 (= the connection width W ₁ where the main body 10 is connected to the waist belt 50). 4/5 or less.
That is, in the positioning pedestal 30 according to the present embodiment, the sinking lateral width W ₃ of the buttocks of the infant B when the length between the main body 10 and the auxiliary holding unit 20 is shortened is the lateral width W of the lower end of the main body 10. ₁ (= the connection width W ₁ where the body portion 10 is connected to the waist belt portion 50) is within a range of 5/10 to 9/10, more preferably within a range of 3/5 to 4/5. Has been.

Furthermore, the auxiliary holding part 20 of the present embodiment is at least 15 cm high from the position where it is connected to the lower end of the main body part 10, and its lateral width shortens the connection length between the main body part 10 and the auxiliary holding part 20. The lateral width W ₃ of the positioning portion 32A where the infant B is received by the positioning pedestal 30 in the above state, that is, set to 1.4 times or less of the lateral width W ₃ of the sag of the infant B.

Thus, the positioning part 32A (folding part 32a is overlapped with the second abutment part 31) that the buttocks of the infant B reaches when the connection length between the main body part 10 and the auxiliary holding part 20 is shortened. width W ₃ positions), i.e., the width W ₃ to sink the buttocks of the baby B, 5 than the lateral width of the lower end of the main body portion 10 W ₁ (= body portion 10 waist belt part 50 connected width W ₁ that is connected to) The infant B having the buttocks received by the positioning portion 32A by being narrow within the range of / 10 to 9/10, more preferably within the range of 3/5 to 4/5 is excessively legged. The leg can be extended from both the left and right sides of the positioning portion 32A inside the right and left side edges of the abutment portion 31 without expanding.
Furthermore, in the auxiliary holding part 20, both legs of the infant B with the buttocks received by the positioning part 32A of the positioning pedestal part 30 are extended from the left and right sides, at least 15 cm above the lower end connected to the lower end of the main body part 10, By making the lateral width at most 1.4 times the sinking lateral width W ₃ of the buttocks of the infant B, the movement of the leg of the infant B which has opened legs, in particular, the movement of the lower leg from the knee joint becomes free. The opening of the leg is not excessively required.

In particular, the lateral width W ₃ of the positioning portion 32A is within a range of 5/10 to 9/10 than the lateral width W ₁ of the lower end of the main body 10 (= the connection width W ₁ where the main body 10 is connected to the waist belt 50). More preferably, the lateral width from the lower end connected to at least the lower end of the main body 10 in the auxiliary holding part 20 to the height of 15 cm is within the range of 3/5 to 4/5, and the lateral width W of the positioning part 32A. If it is 1.4 times less than ₃ , even when targeting a low-age infant B before the neck is soft, the hip joint is widened more than necessary and the hip joint opens too much, The movement of the legs is not restricted, and it is possible to prevent the hip and knee joints from being loaded, and to prevent hip dislocation. Then, the knee is bent at a position higher than the position of the buttocks of the infant B, and the infant B's center of gravity is applied to the buttocks instead of the leg side in a natural open leg posture with an M-shaped spread leg. It can hold the body with less burden.

  Furthermore, according to the baby carrier 1 of the present embodiment, both legs of the infant B whose buttocks reach the positioning portion 32A of the positioning base portion 30 where the connection length between the main body portion 10 and the auxiliary holding portion 20 is shortened are left and right. In the auxiliary holding part 20 extended from both sides, it is connected to the main body part 10 and the waist belt part 50 at least within the range where the height position is 15 cm from the lower end of the main body part 10 and the inclination of the left and right side edge parts is in the range of 90 ° to 140 °. Has been. In the figure, the auxiliary holding part 20 is gradually narrowed toward the lower side of the connection side of the main body part 10 and the waist belt part 50 and is connected to the lower part of the main body part 10. Thereby, even when the infant B at a time when the age before the neck sitting is low, where the leg of about 130 ° is ideal is to be held, the natural leg of the infant B is not hindered. Moreover, there is little compression of a hip joint and a buttocks, and the load concerning the body shape of the infant B at a time when the age is low is less.

  In addition, according to the baby carrier 1 of the present embodiment, in the positioning pedestal portion 30, in the upper part of the second abutment portion 31 applied from the back side of the body of the infant B to the buttocks, gradually downward. In the structure in which the left and right end portions 13B are bent toward the infant B side with respect to the central portion 13A formed by draping the central portion 13A of the holding portion 13 and the end portions 13B on both sides thereof. There is a deep space, so that the buttock of the infant B is positioned at a high position by the positioning base portion 30 in which the connection length between the main body portion 10 and the auxiliary holding portion 20 is shortened by folding in the length direction. In particular, even when the infant B of a young age is a target to be held, the buttocks of the infant B is easy to fall down, and the body shape of the infant B has a higher knee position than the buttocks Type Readily leads it to the state of the leg. That is, the infant B can be easily guided to a state where the center of gravity is placed on the buttocks rather than the knee, and can be held in a stable holding form with little burden on the infant B. Furthermore, the degree of freedom of movement of the leg of the infant B is high, and the movement of the infant B in the M-shape is likely to be free. Therefore, hip dislocation can be prevented and the burden on the infant B is less.

  Furthermore, according to the baby carrier 1 of the present embodiment, the center portion 13A and the end portion 13B constituting the abutment portion 13 of the main body portion 10 are formed by draping and are joined together by a sewing line 13a that is curved inward. In addition, a three-dimensional space with a depth is formed by sewing to the waist belt 50 by sewing the lower end of the main body 10 and the vicinity thereof, and it is easy to drop the buttocks of the infant B Thus, the body shape of the infant B can be easily guided to the state of the M-shaped leg with the knee positioned higher than the buttocks. That is, the infant B can be easily guided to a state where the center of gravity is placed on the buttocks rather than the knee, and can be held in a stable holding form with little burden on the infant B.

Moreover, in the baby carrier 1 of the present embodiment, since the auxiliary holding part 20 is connected to the lower end of the main body part 10 with a narrower width than the main body part 10, the folding of the positioning pedestal part 30 is unfolded and the main body Even when the sinking of the buttocks of the infant B whose height has been increased is received at a low position by the positioning pedestal part 30 that passes between the part 10 and the auxiliary holding part 20 at an original length, that is, the infant B is at a low position. Even when held, the crotch width of the infant B is prevented from being unnecessarily widened to restrict the movement of the legs.
In particular, in the baby carrier 1 of the present embodiment, the width of the main body portion 10 is gradually narrower toward the backrest portion 12 above the abutment portion 13 applied from the back side of the body of the infant B to the buttocks. Therefore, the folding of the positioning pedestal 30 is unfolded, and the infant B having a height is landed on the positioning pedestal 30 where the main body 10 and the auxiliary holding part 20 are connected with the original length. Even at times, the knee joint of the infant B tends to be free.

The positioning pedestal 30 according to the present embodiment is formed integrally and continuously from the main body 10 and the auxiliary holding part 20, so that the positional deviation does not occur and the main body 10 and the auxiliary holding part 20 are moved. The connection strength is stable. In particular, in the state where the length between the main body 10 and the auxiliary holding part 20 is shortened in the positioning base part 30, the connection side between the main body 10 and the auxiliary holding part 20 by receiving the weight of the infant B mainly at the positioning part 32A. Since the bottom of the lower end is raised to support the infant B, the positioning pedestal 30 is formed integrally and continuously from the main body 10 and the auxiliary holding part 20 so as to sufficiently withstand the weight of the infant B. It has sufficient mechanical strength and is in a reliable bridge state.
Furthermore, since the adjustment tool for fixing the folding state of the positioning pedestal 30 and adjusting the length is the pair of female side 33a and male side 33b of the slide fastener 33, the fixing stability in the folded state is also provided. There is no high displacement.

  Therefore, even when the infant B is received by the positioning base 30 with the length between the main body 10 and the auxiliary holding part 20 shortened, the swinging is small and the center of gravity position of the buttocks of the infant B is easy to be stabilized, and the posture is not stable. Even if the infant B at a time when the age before the stable neck is low is an object to be held, the infant B is less likely to wobble and the load on the infant B can be reduced. That is, when the length of the positioning pedestal portion 30 disposed between the main body portion 10 and the auxiliary holding portion 20 is shortened, a stable tension is applied due to the weight of the infant B, so that the buttocks of the infant B can be received. Therefore, even in the case of an infant B of a young age, the position of the body of the infant B is stabilized and a sense of stability is obtained, and the holding posture is less burdensome.

Further, in the present embodiment, the pair of female side 33a and male side 33b of the slide type fastener 33 for adjusting the length of the positioning pedestal 30 is the back side opposite to the side receiving the buttocks of the infant B. Therefore, the pair of female side 33a and male side 33b of the sliding fastener 33 does not directly touch the body of the infant B who has landed. Therefore, the slide type fastener 33 is not injured, and there is little possibility of causing discomfort and discomfort.
Of course, since the positioning pedestal 30 is integrally formed continuously from the main body 10 and the auxiliary holding part 20 and there is no detachable member for attaching the positioning pedestal 30 to the main body 10 and the auxiliary holding part 20, There is no sense of discomfort or discomfort due to the detachable member, and since the detachable member is not required, there is no possibility of losing the positioning base 30.

In addition, a pair of females of the slide type fastener 33 is used as a positioning portion for supporting the weight of the buttocks by receiving the buttocks of the infant B on the positioning base 30 with the length between the main body 10 and the auxiliary holding unit 20 shortened. Although the description has been given of the position 32A where the folded portion 32a folded in the length direction between the side 33a and the male side 33b is brought down to the second abutting portion 31 side and overlapped with the abutting portion 31. When the infant B is received at the positioning portion 32A, the foldable portion 32a may be used while being superimposed on the second abutment portion 31, or the foldable portion 32a may be superimposed on the abutment portion 31. You may use it in the state arrange | positioned on the crotch side of the infant B without it. Thus, the height position of the buttocks of the infant B can also be adjusted by selecting the folding of the folding part 32a on the second abutment part 31. In particular, when the foldable portion 32a is overlapped with the second abutment portion 31, the mechanical strength is high, the position of the buttocks of the infant B is stabilized, and the stability of the holding position is increased.
In addition, it is also possible to separately provide a means for fixing the folded portion 32a to the second abutment portion 31 in an overlapped state.

  Further, in the above embodiment, the positioning pedestal portion 30 is connected at a height (length) position of 10 cm from the lower end near the middle of the auxiliary holding portion 20, but when implementing the present invention, It is possible to connect at a lower position, or the length of the positioning pedestal 30 may be increased to connect at a higher position. In any case, even when the infant B is held at a high position by the positioning pedestal portion 30 with the length between the main body portion 10 and the auxiliary holding portion 20 shortened, the lower end of the main body portion 10 and the auxiliary holding portion 10 is usually set. Even if the bending due to the weight of the infant B is taken into consideration than the original depth, it is designed to be raised by about 5 cm to 10 cm. Further, the connection position to the main body 10 may be lower than or higher than the boundary position between the abutment portion 13 and the backrest portion 12. Preferably, if the original length of the positioning pedestal 30 is within the range of 30 cm to 40 cm, the shaking is small and the burden on the infant B can be reduced.

Next, a usage pattern when the baby B is held using the baby carrier 1 of the present embodiment configured as described above will be described.
When the baby B is held using the baby carrier 1 of the present embodiment, the auxiliary holding portion 20 is disposed closer to the user M, and the main body portion 10 is disposed farther from the user M. The infant B is accommodated between the main body 10 and the auxiliary holding part 20. For example, as shown in FIG. 10 and FIG. 11, the face-to-face holding in which the infant B and the face of the user M face each other or the infant B on the back side of the user M as shown in FIG. 12 and FIG. In the case of a vertical forward piggyback head facing the same direction as the user M, the infant M is disposed between the main body 10 and the auxiliary holding part 20 so that the abdominal side of the body of the infant B faces the user M.

  Then, a buckle connection insertion tool 23 (reference numerals and symbols in FIGS. 10 to 13) provided on both the left and right sides of the auxiliary holding section 20 via connection adjustment sections 22 (reference numerals and symbols are omitted in FIGS. 10 to 13). (Symbol is omitted) is fitted into a buckle connection receiver 24 (not shown in FIG. 10 to FIG. 13) provided on the outer surface side of the boundary between the backrest 12 and the abutment 13 of the main body 10. By connecting the main body part 10 and the auxiliary holding part 20 on the left and right side surfaces by the connecting part 21, the interval between the main body part 10 and the auxiliary holding part 20 is limited, and the main body part 10 and the auxiliary holding part 20 are connected. The left and right inclination of the torso of the infant B accommodated between the holding unit 20 is restrained on the side surface side to prevent the infant B from falling off. Furthermore, the leg of the infant B is passed through an annular shape formed by the auxiliary holding part 20, the main body part 10, and the connection part 21, so that the main body part 10 is caused by a fall caused by the curling of the infant B, a forward bending of the user M, or the like. The infant B can be prevented from falling from the side of the head rest 11.

The belt 40 is hung around the waist of the user M around the shoulder of the user M, and the waist belt portion 50 disposed at the lower ends of the auxiliary holding unit 20 and the main body 10 is attached to both ends of the buckle. By fitting the connecting plug 53 and the connecting receiver 54 (the symbols and symbols are omitted in FIGS. 10 to 13), connecting them in a ring and fixing them around the waist of the user M, the baby carrier 1 It is attached to the user M. As a result, the weight of the infant B accommodated between the main body 10 and the auxiliary holding part 20 is distributed to both shoulders, back and waist of the user M, and the infant B is held by a cuddle or a piggyback.

  In addition, as described above, in the baby carrier 1 of the present embodiment, by adjusting the belt length of the adjustment belt portion 42 by the adjusters 42c and 42b of the adjustment belt portion 42 in the pair of left and right shoulder belt portions 40, The belt length of the shoulder belt portion 40 can be adjusted. Furthermore, by connecting and engaging the connection insertion tool 46c and the connection receiver 46d of the buckle of the shoulder belt adjustment portion 46 provided on the shoulder hook portion 41, the distance between the left and right shoulder belt portions 40 is fixed at a predetermined distance, The left and right shoulder belt portions 40 can be prevented from coming off the user's M shoulder. Further, the adjuster function is provided in one or both of the connection plug 46b and the connection receiver 46d, so that the length of the shoulder belt adjustment section 46 is adjusted, and the distance between the left and right shoulder belt sections 40 is determined. (Distance) can also be adjusted. In addition, the position of the shoulder belt adjusting portion 46 can be adjusted by the slide belt 47 and the belt moving adjuster 48 provided on the shoulder portion 41. Therefore, the shoulder belt 40 can be disposed at a position where the burden on the user M is low according to the body shape of the user M and the like.

  Thus, the distance between the pair of left and right shoulder belt portions 40 can be adjusted by the shoulder belt adjustment portion 46, and the length of the shoulder belt portion 40 can be adjusted by the adjusters 42c and 42b of the adjustment belt portion 42. In addition, the slide belt 47 and the belt movable adjuster 48 can adjust the position of the shoulder belt adjusting portion 46, so that it can be adjusted according to the body shape of the user M and the position of the infant B holding or carrying the infant B. Thus, it is possible for the user M to easily set the optimal position where the infant B can be easily held. Further, the distance between the infant B and the user M can be easily adjusted, and the holding posture for the infant B can be set appropriately. For this reason, even when holding an infant B of a young age whose posture is unstable, the shoulder belt portion 40 can be fitted to the body shape of the user M, and the infant B can be held in close contact with the user M and stably held. Is possible. Further, the infant B can be easily adjusted to a holding mode with less burden even when the infant B is held at a low age by adjusting the center of gravity of the buttocks rather than the knee. Furthermore, even when the baby B that has grown and grown is held, the wearing state of the shoulder belt portion 40 to the user M can be adjusted to hold the baby B in an appropriate holding posture that does not feel cramped. it can.

In the waist belt portion 50, the belt length of the waist belt portion 50 can be adjusted by adjusting the length of the length adjusting portion 52 by an adjuster function provided on the buckle. Can be fitted around the waist and the burden on the user M can be reduced.
In the baby carrier 1 of the present embodiment, the pair of left and right shoulder belt portions 40 may be stopped after the waist belt portion 50 is fastened to the waist of the user M. After being stopped, the waist belt portion 50 that is fastened to the waist of the user M may be stopped, which is convenient.

  And in the baby carrier 1 of this Embodiment, the positioning base part integrally formed continuously from the main-body part 10 and the auxiliary holding part 20 between the main-body part 10 in which the infant B is accommodated, and the auxiliary holding part 20 In the positioning pedestal portion 30, a pair of the female side 33a and the male side 33b of the sliding fastener 33 are attached at a predetermined distance. For this reason, by engaging the pair of female side 33a and the male side 33b of the slide type fastener 33 and closing the fastener, a part in the length direction of the positioning base 30 can be fixed in the folded state, 10 and the auxiliary | assistant holding | maintenance part 20 can be shortened. That is, the positioning pedestal 30 can freely adjust the depth between the main body 10 and the auxiliary holding part 20 and can adjust the sinking depth of the buttocks of the infant B.

  Therefore, for example, as shown in FIG. 10, when the infant B is held in a face-to-face holding in which the infant B and the face of the user M face each other, Since the position of the buttocks of the infant B can be increased by the positioning pedestal portion 30 in which the connection length between the auxiliary holding portions 20 is shortened, the main body portion 10 and the auxiliary holding portion 20 may sink or be buried. The head support part 11, the back support part 12 and the heel support part 13 of the main body part 10 are applied to the appropriate positions of the body of the infant B, so that the burden on the infant B can be reduced and comfortable holding is possible. .

  In particular, even in the case of a low-age infant B who has an unstable posture before sitting on the neck, the back support part 12 and the abutment part 13 of the main body part 10 are assigned to appropriate positions of the body of the infant B, The head support part 11 of the main body part 10 is appropriately disposed on the head of the infant B, and further, from the surface of the boundary part between the head support part 11 and the back support part 12 on the inner surface side (infant B side) of the main body part 10. Since the projecting connecting portion 14 having a high cushioning property can guard the neck and the side of the head of the infant B, the neck and the head of the infant B are appropriately supported by the rear and the side of the head. Even with a low-age infant B who is likely to be burdened by vibration caused by walking of the user M or the like, the burden on the body of the infant B, particularly the head and neck, can be reduced.

Further, the buttocks of the infant B are placed on the positioning pedestal portion 30 in a state where the pair of the female side 33a and the male side 33b of the sliding fastener 33 are engaged to shorten the connection length between the main body portion 10 and the auxiliary holding portion 20. In the positioning portion 32A where the sun sinks, the lateral width W ₃ in the left-right direction (horizontal direction) is 5/10 to the lateral width W ₁ of the lower end of the main body portion 10 (= the connection width where the main body portion 10 is connected to the waist belt portion 50). 9cm, more preferably narrow within the range of 3/5 to 4/5, and at the auxiliary holding part 20, at least 15 cm from the position connected to the lower end of the main body part 10. Since the horizontal width up to the height is formed to be 1.4 times or less the horizontal width of the positioning portion 32A, even if the infant B of a young age whose posture before the neck is unstable is unstable, the infant B The crotch width is expanded more than necessary, It can be prevented from or is particularly restricted movement of the knee joint. Therefore, the body shape of the infant B can be held in a natural posture in which the body shape of the infant B is opened in an M shape with the knee positioned higher than the buttocks, and the body shape of the infant B is less burdensome.

  In particular, according to the baby carrier 1 of the present embodiment, the leg of the infant B with the buttocks sunk in the positioning portion 32A of the positioning base portion 30 in which the connection length between the main body portion 10 and the auxiliary holding portion 20 is shortened. The lower end of the main body 10 is inclined at an angle within a range of 90 ° to 140 ° at a height of 15 cm from a position connected to at least the lower end of the main body 10 of the auxiliary holding portion 20 extending from the left and right sides. Because it is connected to the hips, compression of the hips and hips is possible without interfering with the natural leg of infant B when the age is low before the neck is sitting, which is ideal for a leg of about 130 ° There are few.

  Furthermore, according to the baby carrier 1 of the present embodiment, the abutment formed by draping that is joined to the both sides of the second abutment portion 31 of the positioning pedestal portion 30 by the inwardly curved sewing line 13a. The vicinity of the boundary between the central portion 32A of the portion 13 and the left and right end portions 32B is exposed, and the left and right end portions 13B can be bent toward the infant B side with respect to the central portion 13A, and has a depth. A three-dimensional space can be formed. Therefore, the movement of the infant B accommodated between the main body part 10 and the auxiliary holding part 20 in a leg-shaped manner tends to be free.

  In addition, the center portion 32A of the abutment portion 13 and the left and right end portions 32B formed by draping that are joined together by the inwardly curved sewing line 13a allow predetermined flexibility and allowance in the holding state of the infant B. A central portion 13A formed of a material having flexibility, elasticity, buffering properties, and the like is easily bent backward. Accordingly, the buttocks of the infant B are likely to fall down, the infant B is more likely to be positioned at the center of gravity than the knee, and the holding state is low even when the infant B is held at a low age, and the position of the buttocks of the infant B is appropriate. It is stabilized at the position, and the holding stability of the infant B is high.

  Thus, according to the baby carrier 1 of the present embodiment, it is possible to stably hold an open leg posture with less burden even when the infant B at a time when the age before sitting on the neck is low is held forward.

  In addition, as shown in FIG. 12, in the case where the infant B is turned forward on the back side of the user M in the same direction as the user M, the positioning pedestal portion that connects between the main body portion 10 and the auxiliary holding portion 20. Since the length of 30 can be shortened to raise the position of the buttocks of the infant B, the position of the infant B can be held at a position further away from the position of the waist of the user M. Therefore, the spine of the user M and the infant The shape of the curved spine line of the infant B easily follows the shape of the curved spine line of the user M without repulsion of the spine of the B, so that the infant B can easily adhere to the user M. Therefore, it is possible for the user M and the infant B to hold comfortably with a comfortable posture. In particular, the user M carrying the infant B is less likely to feel the weight of the infant B than the baby and can easily hold it. In addition, since the infant B easily comes into close contact with the user M, the infant B is unlikely to be warped backward.

On the other hand, in the state where the main body 10 and the auxiliary holding part 20 are connected by the original length of the positioning base part 30 without engaging the pair of female side 33a and male side 33b of the sliding fastener 33, positioning is performed. Since the pedestal portion 30 overlaps and follows the main body portion 10 and the auxiliary holding portion 20, as shown in FIGS. 11 and 13, the sinking depth of the buttocks of the infant B received by the positioning pedestal portion 30 becomes deeper.
Therefore, even when the infant B grows up and becomes taller, the positioning base 30 having the original length between the main body 10 and the auxiliary holding part 20 positions the buttocks of the infant B at a low position. By doing so, the head support part 11, the back support part 12 and the heel support part 13 of the main body part 10 are assigned to appropriate positions of the body of the infant B, thereby enabling a comfortable holding with a small burden on the infant B. .

  As shown in FIG. 13, even when the infant B's buttocks are landed on the positioning pedestal 30 having the original length between the main body 10 and the auxiliary holding portion 20, the assisting portion is supported. The holding part 20 and the main body part 10 are connected by the connecting part 21, and the leg of the infant B is passed through the ring formed by the auxiliary holding part 20, the main body part 10 and the connecting part 21, so that the infant B warps back. Can prevent falling by.

As described above, according to the baby carrier 1 of the present embodiment, the length of the positioning pedestal portion 30 disposed and disposed on the inner surface side between the main body portion 10 and the auxiliary holding portion 20 is the sliding fastener 33. Since the pair of female side 33a and male side 33b are adjustable, the height of the infant B and the height position of the infant B to be held can be adjusted according to the holding form of the infant B or the piggyback.
In particular, the lateral dimension of the positioning portion 32A where the infant B is received by the positioning base 30 when the length passing between the main body 10 and the auxiliary holding part 20 is shortened and the assist applied to the crotch side of the body of the infant B By specifying the width dimension of the holding portion 20, even an infant B at a low age can stably hold with little burden, and an open leg that does not place a burden according to the age, size, and growth of the infant B Can be held in a posture.
A pair of female side 33a and male side 33b of the slide type fastener 33 for adjusting the length of the positioning pedestal 30 are attached to the back surface of the positioning pedestal 30 opposite to the landing side of the infant B. Therefore, the height position of the buttocks of the infant B can be adjusted without causing the infant B to feel uncomfortable or uncomfortable.

  As described above, the baby carrier 1 according to the above embodiment includes the main body 10 that is applied to the body of the infant B on the opposite side to the user M side and supports the infant B, and the lower end of the main body 10. And the auxiliary holding part 20 applied to the body of the infant B on the opposite side of the main body part 10 and the main body part 10 and the auxiliary holding part 20 on the opposite side of the main body part 10 and the auxiliary holding part 20 from the main body part 10 and the auxiliary holding part 20 It is formed continuously and passed between the main body part 10 and the auxiliary holding part 20, and is adjusted by the folding length adjustment by the pair of female side 33a and male side 33b of the slide type fastener 33. A positioning pedestal 30 for adjusting the depth between the main body 10 and the auxiliary holding part 20 by adjusting the length between the auxiliary holding parts 20 and positioning the sinking depth of the buttocks of the infant B; Connected to the holding unit 20 to hold the infant B A pair of shoulder belt portions 40 that are hung on the shoulders of the user M, and a waist belt portion 50 that is connected to the lower end portions of the main body portion 10 and the auxiliary holding portion 20 and is worn around the waist of the user M. Is.

  Therefore, according to the baby carrier 1 according to the above-described embodiment, the infant housed between the main body 10 and the auxiliary holding portion 20 on the positioning base 30 disposed between the main body 10 and the auxiliary holding portion 20. B is received, but a pair of female side 33a and male side 33b of slide type fastener 33 attached to the back surface of positioning pedestal portion 30 at a predetermined distance are engaged, and length adjustment portion 32 is folded. When the length of the positioning pedestal 30 between the main body 10 and the auxiliary holding part 20 is shortened, the sinking depth of the buttocks of the infant B accommodated between the main body 10 and the auxiliary holding part 20 becomes shallow. When the folding of the height length adjustment unit 32 is expanded to increase the length of the positioning base 30 between the main body 10 and the auxiliary holding unit 20, the height adjustment unit 32 is accommodated between the main body 10 and the auxiliary holding unit 20. Infant Sinking depth of the buttocks is deep, you can adjust the height of the infant B holding by adjusting the length of the positioning pedestal 30.

  Therefore, even in a small-age infant B with a small body, the length of the positioning pedestal 30 between the main body 10 and the auxiliary holding unit 20 is shortened by folding the length adjusting unit 32, and the lower end of the main body 10 Since the infant B can be held at a position higher than the connection position of the lower end portion of the auxiliary holding part 20, the infant B does not sink or be buried between the main body part 10 and the auxiliary holding part 20, The position of the head of the infant B is appropriately arranged on the head support part 11 of the main body part 10 that protects the infant B, so that the burden on the infant B can be reduced and comfortable holding is possible. Further, when the infant B grows and the body becomes large, the length adjustment unit 32 is expanded and the length of the positioning base 30 between the main body 10 and the auxiliary holding unit 20 is increased. The infant B is held at a low position on the connection side between the lower end of the main body 10 and the lower end of the auxiliary holding part 20, and the head rest 11, the back rest 12, and the saddle rest 13 of the main body 10 are held by the infant B. Protects the body at an appropriate position and enables comfortable holding. Also, the height position of the infant B can be adjusted to a comfortable holding position for the user M. The holding height position of the infant B is adjusted according to the age, size, and growth of the infant B that is held in this way, and the infant B and the user M can be held with less burden.

In addition, since the positioning pedestal portion raises the sinking depth of the buttocks of the infant to the upper level, the opening width of the crotch width of the infant is not affected by the width of the lower end portion of the main body, and the positioning pedestal Since the infant can fit the leg into the space from the lower part of the part to the closed lower end where both the auxiliary holding part and the main body part are connected, the hip joint is opened for younger infants. It is possible to prevent overshoot.
Further, since the positioning base 30 for receiving the buttocks of the infant B is formed integrally and continuously from the main body 10 and the auxiliary holding part 20, the connection strength is stable without causing a displacement. The positioning base part 30 is not detached from the main body part 10 and the auxiliary holding part 20 due to the weight of the infant B, and the reliability is high, and the collar part is received by the positioning base part 30 whose length is shortened. It is difficult for the infant M to swing even by vibration caused by the user's walking, etc., and the center of gravity position of the buttocks of the infant B is easy to be stabilized. And can be held stably.
In this way, the holding height position of the infant B can be adjusted, and it is possible to maintain an open leg posture that does not impose a burden according to the age, size, and growth of the infant B, and the age is low. Even the infant B at the time allows stable holding with little burden.

In particular, the positioning pedestal 30 of the baby carrier 1 according to the above-described embodiment is configured to engage a pair of female side 33a and male side 33b of a slide type fastener 33 that is attached to the back surface thereof by a predetermined distance apart. The folding state in the length direction is fixed by the width W ₃ of the positioning part 32A as the sinking lateral width of the buttocks of the infant B when the length between the main body 10 and the auxiliary holding part 20 is shortened by the folding, in the range of 5 / 10-9 / 10 of the width W ₁ of the lower end portion of the main body portion 10 which connects the auxiliary holding portion 20, and more preferably, it is formed narrower in a range of 3 / 5-4 / 5 Yes.

In the positioning pedestal 30, the lateral width W ₃ of the positioning part 32 A where the buttocks of the infant B are received when the length between the main body 10 and the auxiliary holding part 20 is shortened by folding in the length direction, that is, the infant B Since the sinking width W ₃ of the buttock is narrow within the range of 1/3 to 2/3 of the width W ₁ of the lower end of the main body 10, the infant B of a younger age before sitting on the neck is held. Even as a subject, the hip width of the infant B is unnecessarily widened, and the hip joint is prevented from opening too much, dislocation of the hip joint is prevented, and it is possible to hold the load with a natural open leg posture with an M-shaped open leg. To do.

In addition, the auxiliary holding part 20 of the baby carrier 1 according to the above embodiment has an auxiliary width between the left and right sides from the connection position with the lower end of the main body part 10 to a height position of 15 cm at the maximum. it is not more than 1.4 times the width W ₃ of the positioning portion 32A as buttocks sink width of infant B when shortening the length between the holding portion 20.
In particular, in the auxiliary holding part 20, the width between the left and right sides from the connection position with the lower end part of the main body part 10 to the height position of 15 cm is short at the maximum between the main body part 10 and the auxiliary holding part 20. Since the width W ₃ of the positioning portion 32A at which the buttocks of the infant B is received, that is, 1.4 times or less the sinking width W ₃ of the buttocks of the infant B, the infant B of the younger age before the neck is held is held. As a target, leg movements, especially knee joint movements, are not restrained, and infant B's cramped feeling is also released, allowing a less legible holding with a natural leg position with an M-shaped leg. And

As described above, the baby carrier 1 according to the embodiment is connected to the main body 10 that is applied to the body of the infant B on the opposite side to the user M side and supports the infant B, and the lower end of the main body 10. The auxiliary holding part 20 applied to the body of the infant B on the side opposite to the main body part 10, and the main body part 10 and the auxiliary holding part 20 on the opposite side of the main body part 10 and the auxiliary holding part 20, continuously from the main body part 10. The main body part 10 and the auxiliary holding part 20 are formed and arranged between the main body part 10 and the auxiliary holding part 20 and are adjusted by the folding length of the pair of female side 33a and male side 33b of the slide fastener 33. A positioning pedestal 30 for positioning the sinking depth of the buttocks of the infant B, and the auxiliary holding part 20 to freely adjust the depth between the main body part 10 and the auxiliary holding part 20 by adjusting the length between 20 The user who is connected to and holds the infant B A pair of shoulder belts 40 to be hung on the shoulders of the body, and a waist belt part 50 connected to the lower end part of the main body part 10 and the auxiliary holding part 20 and mounted around the waist of the user M, and a positioning base part 130 is a horizontal width W ₃ of the lower part of the main body 10 that is 10 to 9/9 of the horizontal width W ₁ of the lower end of the main body 10 when the length between the main body 10 and the auxiliary holding unit 20 is shortened. 10, more preferably, a width within a range of 3/5 to 4/5, and the auxiliary holding portion 20 is within a range of 15 cm from the connection position with the lower end of the main body portion 10. The horizontal width of the left and right sides up to the inner height position is 1.4 times or less of the sinking width W ₃ of the buttocks of the infant B when the length between the main body 10 and the auxiliary holding portion 20 is shortened at the maximum. It is.

That is, the baby carrier 1 according to the above-described embodiment is attached to the user M by a pair of left and right shoulder belt portions 40, applied to the body of the infant B and supporting the infant B over a wide area, One end of the main body 10 is connected to the lower end of the main body 10, and the auxiliary holding section 20 is applied to the body of the infant B on the opposite side of the main body 10. And a positioning pedestal portion 30 that is passed between the auxiliary holding portion 20 and positions the sinking depth of the buttocks of the infant B, and the main body portion 10 is adjusted by adjusting the length of the positioning pedestal portion 30 in the length direction. The width of the sinking width W ₃ of the buttocks of the infant B when the length between the main body 10 and the auxiliary holding portion 20 is shortened and the lower end of the main body portion 10 is adjusted. 5/10 or more of the width W ₁ of the part, 9 / 10 or less, more preferably 3/5 or more and 4/5 or less, and the auxiliary holding part 20 is connected to the lower end part of the main body part 10. The horizontal width of the left and right sides from the position to a height of 15 cm is at most 1.4 times the horizontal width of the sinking of the buttocks of the infant B when the length between the main body portion 10 and the auxiliary holding portion 20 is shortened. It is what is.

Therefore, according to the baby carrier 1 according to the above-described embodiment, the positioning pedestal portion 30 has the sinking lateral width W ₃ of the buttocks of the infant B when the length between the main body portion 10 and the auxiliary holding portion 20 is shortened. The width of the width W ₁ of the lower end of the main body 10 is within a range of 5/10 to 9/10, more preferably within a range of 3/5 to 4/5, and the auxiliary holding portion 20 is formed. Infant B when the width between the left and right sides from the connection position with the lower end of the main body 10 to the height position of 15 cm is at most short between the main body 10 and the auxiliary holding part 20 Because it is 1.4 times or less of the sinking width of the buttocks, even if the infant B is to be held before the neck is held, the crotch width of the infant B is widened more than necessary and the hip joint is too open or leg Without restraining the movement of the hip, preventing dislocation of the hip joint, It can be held with a low load by a natural open leg posture.
Further, since the lower end of the main body 10 is a predetermined width wider than the horizontal width of the buttocks of the infant B when the length between the main body 10 and the auxiliary holding part 20 is shortened, the positioning base 20 can be folded. Even when the buttocks of the infant B are received on the positioning base 30 by extending the length of the main body 10 and the auxiliary holding part 20 so as to be extended, the infant can be accommodated by an appropriate wide dimension at the lower part of the main body 10. The buttocks of B are widely covered and stable holding is possible without placing a burden on the open leg posture. Furthermore, since the crotch width of the infant B is opened and held with an appropriate width, a feeling of close contact with the user M is obtained and a sense of security is increased, thereby providing a comfortable holding feeling.

Then, when the length between the main body 10 and the auxiliary holding part 20 is shortened by folding in the length direction, the lateral width W ₃ of the positioning portion 32A where the buttocks of the infant B are received, that is, the sinking lateral width of the buttocks of the infant B Since the lower end of the main body 10 is wider than W _3, the buttocks of the infant B are placed on the positioning pedestal 30 where the folding is unfolded and the length passing between the main body 10 and the auxiliary holding part 20 is increased. Even when it is received, the buttocks of the infant B are widely covered by the appropriate wide dimensions of the lower portion of the main body portion 10 and can be stably held without placing a burden on the open leg posture.

Further, since the positioning pedestal portion 30 is integrally formed continuously from the main body portion 10 and the auxiliary holding portion 20, a cushioning material or the like that is attached to the main body portion 10 and the auxiliary holding portion 20 is separately prepared for raising the bottom. Since it is not necessary, there is no risk of losing it, and it is possible to hold it comfortably without the stuffiness or heat of the cushioning material.

  Thus, according to the baby carrier 1 according to the above-described embodiment, the holding position of the baby B can be adjusted, and the baby carrier 1 is held in an open leg posture that does not impose a burden according to the growth of the baby B. In addition, the infant B at a low age can be stably held with little burden, and even if the infant B is held for a long time, the fatigue of the infant B can be reduced. And since the burden to the infant B is small, it is advantageous for laying down especially when the infant B of a low age is held, and a comfortable sleep environment can be created.

  Moreover, the auxiliary | assistant holding | maintenance part 20 of the baby carrier 1 which concerns on the said embodiment is a horizontal lower end which is a connection side with the lower end part of the main-body part 10, and the right-and-left both-sides edge from there to a height position of 15 cm. The formed angle is in the range of 90 ° to 140 °.

Here, the angle between the lower end in the horizontal direction, which is the connection side with the lower end of the main body 10, and the left and right side edges to the height position of 15 cm is within the range of 90 ° to 140 °. In the auxiliary holding part 20, the positioning pedestal part 30 when the length between the main body part 10 and the auxiliary holding part 20 is shortened within the height range from the lower end connected to the main body part 10 to 15 cm. Since the edges of both sides of the auxiliary holding part 20 touch both legs of the infant B that is received at the high position by receiving the buttocks, the edges of both sides of the auxiliary holding part 20 that touch the legs of the infant B are touched. By setting the inclination within the range of 90 ° to 140 ° with respect to the horizontal direction of the lower end, when the infant B in the low-age period before sitting on the neck is to be held, the hip joints and buttocks of the body of the infant B Ideal for the infant B Is obtained easily leads naturally form close to the open leg posture of a about 130 °.

  Therefore, according to the baby carrier 1 according to the above-described embodiment, the auxiliary holding portion 20 has the lower end in the horizontal direction that is the connection side to the lower end portion of the main body portion 10 and the left and right sides from there to a height position of 15 cm. Since the angle formed by the edge is in the range of 90 ° or more and 140 ° or less, it does not interfere with the natural legging of infants at low ages, especially when the leg of about 130 ° is ideal. In addition, the infant's body is less pressed against the hip joints and buttocks, and the infant's body shape can be held with less burden. Therefore, even when the infant B at a time when the age before the neck sitting is low, which is ideal for the 130 ° open leg posture, can be led to a posture close to the open leg posture.

  Furthermore, when the baby carrier 1 according to the present embodiment folds the positioning pedestal portion 30 in the length direction to shorten the length between the main body portion 10 and the auxiliary holding portion 20, the folded portion 32a is an infant B. Since it becomes the positioning part 32A which catches the buttocks, the sense of stability increases by increasing the volume of the folded part 32a. Moreover, the thickness of the positioning part 32A, that is, the height can be adjusted by selecting the folding overlap, and the selection range of the position of the holding height of the infant B is widened.

Furthermore, the main body 10 of the baby carrier 1 according to the present embodiment is such that the left and right end portions 13B of the main body portion 10 of the baby support portion 13 can be bent toward the infant B side with respect to the center portion 13A. The space in which the space is accommodated forms a three-dimensional space with a depth. Therefore, according to the baby carrier 1 according to the present embodiment, even if the infant B at the age of a low age is held and protected so as to cover (wrap) the entire buttocks of the infant B, the leg is opened in an M shape. The movement is not easily restrained, the cramped feeling of the infant B is released, and the infant B at a time when the age is low can be held with less burden. Further, when viewed from the outer surface side opposite to the infant B side, it is possible to give a clean impression that is three-dimensional and slim. Furthermore, it is easy to maintain a natural open leg posture with an M-shaped open leg where the knee is bent at a position higher than the position of the buttocks of the infant B, and the center of gravity of the infant B is guided to a holding form on the buttocks instead of the leg side. It becomes easy, and holding with little burden is enabled by the body shape of the infant B.
More preferably, it can be bent by joining by draping, and the waist belt part 50 can be bent by sewing curved toward the center side (inner side) at the joining part, or by sewing the lower end of the main body part 10 and the vicinity thereof. By stitching together, the depth of the baby B is further increased, and the buttocks of the infant B can be easily lowered, and the position of the center of gravity is determined from the position of the buttocks of the infant B, thereby reducing the burden on the body shape of the infant B.

In addition, in the baby carrier 1 according to the present embodiment, the weight of the infant B is provided by having a waist belt portion 50 that is connected to the lower portion of the main body portion 10 and the auxiliary holding portion 20 and is worn around the waist of the user M. Is distributed over the shoulder, back and waist of the user M to lighten the burden on the shoulder of the user M. However, when the present invention is implemented, the waist belt portion 50 can be omitted. is there. That is, since the infant B is held by placing the infant B between the main body 10 and the auxiliary holding part 20, the waist belt part 50 is not necessarily required, and the left and right shoulder belt parts 40 are not necessarily required. It is good also as a form which supports the weight of the infant B only and holds the infant B or rides.

In the baby carrier 1 of the above embodiment, the shoulder belt portion 40 is connected to the auxiliary holding portion 20 in the vertical direction. However, when carrying out the present invention, the infant B can be held. If possible, the shoulder belt portion 40 may be connected to the main body portion 10, or the shoulder belt portion 40 may be connected to the main body portion 10 and the auxiliary holding portion 20. In any case, it may be configured to be connected to a position that does not interfere with the body of the infant B and to form a ring through which the shoulder of the user M is passed.
Further, the pair of left and right shoulder belt portions 40 is not limited to being mounted in parallel to the shoulder of the user M, and the pair of left and right shoulder belt portions 40 may be mounted in a cross-hung manner.

  Further, in the baby carrier 1 of the above-described embodiment, the positioning base 30 uses a pair of female side 33a and male side 33b of the sliding fastener 33 as a fixing means for fixing the folded state. Although the length adjustment by folding the height adjusting portion 32 is possible, when the present invention is implemented, the number of sliding fasteners 33 can be increased and the folding length can be selected in stages. It is. The range of selection for adjusting the height position of the buttocks of the infant B is also increased by adjusting the number of folded sheets.

The means for fixing the fold is not limited to the sliding fastener 33, and may be a snap, a button and loop, a hook and ring, an adhesive cloth, or the like, or may be attached by attaching a separate adjuster or the like. As long as a member (part) that serves as a fixing means is fixed to the positioning pedestal 30, it is easy to manage without losing it. Also good.
Furthermore, when implementing this invention, such a slide type fastener 33 grade | etc., Can also be attached to the infant B side in the positioning base part 30. FIG.

In addition, in the baby carrier 1 of the present embodiment, the auxiliary holding part 20 and the connection part 21 can increase the effect of preventing the infant B from falling, and infants and infants can be handled even if they are not skilled in handling a baby or a piggyback. The arrangement position of B becomes easy to understand.
