[0004]
[Prior art]
  Bottom underwear that fits the buttocks of girdle, shorts, etc. has widespread body repair functions such as stomach hold and hip up. However, such bottom underwear had the subject of sweating when worn in the summer, and feeling of stuffiness and heat.
[0005]
  In particular, the rear center of the buttocks shown in FIG.Rupture90, thisRuptureIn the sacral portion 92 communicating above 90 and the crotch portion 94 communicating below, experimental data indicating that the skin temperature is high and the amount of perspiration is large are obtained. It is felt.
[0006]
  Some existing products use materials that are uniformly highly breathable. Also,RuptureVarious types of underwear using a breathable material such as a mesh fabric have been proposed around the crotch and waist areas (utility model registration 305211, No. 49-58525, No. 3-54092, No. 60-117804, No. 43-16648, etc.).
[0007]
[Problems to be solved by the invention]
  However, since air movement does not occur much only by improving air permeability, the effect of eliminating the feeling of heat accumulation is not so high, and the current situation is that the wearer does not feel the coolness.
[0008]
  The present invention has been made to solve the above problems, while maintaining the conventional modeling function, sacrum, crotch andRuptureAn object of the present invention is to provide a buttock-covered garment that can eliminate the feeling of stuffiness and heat.
[0009]
[Means for Solving the Problems]
  In order to achieve the above object, a buttock-covered garment according to the present invention is a buttock-covered garment that is in close contact with the buttock when worn and covers at least the buttock, and is worn above the cracked portion at the rear center of the buttock when worn. The air permeability of at least the first part including at least one of the vicinity of the sacrum and the vicinity of the lumbar vertebra and the second part including at least the lower part of the ruptured part is more than the air permeability of the left and right parts across the ruptured part and the ruptured part. The first portion communicates upward with respect to a vertically long space that is formed in a rupture portion at the rear center of the buttocks when worn and changes in size as the leg moves during walking. The location is configured to communicate downward with respect to the space, and the space includes an air flow passage that connects between the upper portion and the lower portion of the cracked portion.The air permeability of the first part is better than the air permeability of the second partIt is characterized by that.
[0010]
  Here, the first location may include only one or both of the vicinity of the sacrum and the vicinity of the lumbar vertebrae, or may include both, and the area may be larger while including the vicinity of the sacrum and the vicinity of the lumbar vertebrae. The second part isRuptureSometimes it ’s just down,RuptureIn some cases, the lower part of the crotch is included.
[0011]
  According to the present invention, the rear center of the buttocks when wornRuptureA first location that includes at least one of the vicinity of the sacrum and the vicinity of the lumbar spine, and at leastRuptureBreathability of the second part including the lower part,RuptureAnd theRuptureBecause it is better than the breathability of the left and right parts across the heel, in the heel area where it is easy to feel a sense of stuffiness and heatRuptureAn air inlet and outlet are formed above and below the air. For this reason,RuptureIn addition, air can be circulated and air permeability better than that of the conventional one can be realized, and the feeling of stuffiness and heat accumulation at the buttock can be eliminated. Moreover, since it can implement | achieve with the structure of providing a difference in air permeability, modeling functions, such as a conventional hip, can be hold | maintained.
[0012]
  Also,The first part communicates upward with a vertically long space that is formed in a rupture part at the rear center of the buttocks when worn and changes in size with leg movement during walking, and the second part is the space. In contrast, the space serves as an air flow passage connecting the upper and lower portions of the cracked portion.
[0013]
  Therefore,The shape of the vertically long space is changed by an action such as walking, and an air flow is generated by the action itself. The air permeability of the first part communicating upward with respect to such a vertically long space and the second part communicating downwardly,RuptureAnd theRuptureSince the air permeability of the left and right parts is improved, the air permeability is relatively poor when the size of the vertically long space changes as the legs move during walking.RuptureAnd theRuptureThe left and right portions are the pump portion, and the first and second portions with relatively good air permeability are the intake and exhaust portions, and the following air flow is generated by the bellows phenomenon.
[0014]
  That is, when one foot comes out forward during walking as shown in FIG.RuptureBecause the space ofRuptureThe air accumulated in the flow is discharged to the first location communicating upward and the second location communicating downward. Then, when both feet are aligned as shown in FIG. 2 (c), the above described as shown in FIG. 2 (d).RuptureSince the space of the outside expands, the outside air is sucked from the first place and the second placeRuptureFlows into the space.
[0015]
  In this way, with the walking movement during wearing, air flow is generated in the first part, the second part, and the space of the rupture part, so that the breathability of these parts is further improved, The feeling of heat accumulation can be eliminated.
In particular, the present invention is characterized in that the air permeability at the first location is better than the air permeability at the second location. In general, the first location above the fissured portion is a location where heat is more likely to accumulate than the second location, and the body temperature itself is slightly higher. For this reason, while improving the air permeability of both the 1st and 2nd location, between these, it is constituted so that the air permeability of the 1st location may become better than the air permeability of the 2nd location. In the space of the cracked portion, ventilation from the lower side to the upper side is promoted, heat dissipation at the first location is promoted, and for example, the wearer can easily feel coolness.
At this time, by adopting at least one of a method of using a material with good air permeability and a method of increasing the area, the air permeability of the first location can be made better than the air permeability of the second location. . That is, only a method using a material having good air permeability may be employed, only a method of increasing the area may be employed, or a combination of both may be employed.
[0016]
  In the buttock-covering garment according to the present invention, various methods can be adopted to provide a difference in air permeability.For example, the firstAnd the second part,RuptureAnd theRuptureEven if a difference in breathability is provided by using different fabrics on the left and right parts across theGood oneBy using a fabric in which a portion with good breathability and a portion with poor breathability are knitted, the first place and the second place,RuptureAnd theRuptureA difference in air permeability may be provided between the left and right portions across the wall.
[0017]
  Also, the rupture partAnd theRuptureEven if the air permeability is deteriorated relative to the first part and the second part by applying resin processing to the left and right parts, for example, adhesion of resin, etc.Good, firstBy applying opal processing to the location and the second location, that is, processing to melt and thin the dough,RuptureAnd theRuptureThe air permeability may be relatively improved with respect to the left and right parts. As described above, there is an advantage that the configuration of the present invention can be realized by various methods.
[0018]
  First location according to the present inventionThen at least the ruptureBreathability in the area of a substantially isosceles triangle with the top near the top ofRuptureAnd theRuptureIt is characterized by being better than the air permeability of the left and right parts. ConcernedRuptureThe area of an approximately isosceles triangle with the apex near the top ofRuptureSince this is a portion directly connected to the space, the air flow during walking due to the above-mentioned bellows phenomenon can be generated by relatively improving the air permeability in at least the region of the approximately isosceles triangle, and the first location as well asRuptureThe feeling of stuffiness and heat can be eliminated.
[0019]
  Similarly, the second location according to the present inventionThen at least the ruptureBreathability in the area of an approximately isosceles triangle with the vicinity of the lower end ofRuptureAnd theRuptureIt is characterized by being better than the air permeability of the left and right parts. ConcernedRuptureThe area of an approximately isosceles triangle whose apex is near the lower end ofRuptureThe air flow during walking due to the above-mentioned bellows phenomenon can be generated by relatively improving the air permeability at least in the area of the approximately isosceles triangle, and the second location. as well asRuptureThe feeling of stuffiness and heat can be eliminated.
[0020]
  The present inventionSo firstA mesh ground can be employed as the fabric used in the second and second locations. In addition, the crotch cloth which contact | abuts the crotch part of a 2nd location may be made into a mesh ground, and cloth, such as cotton, may be further attached inside this crotch cloth.
[0023]
  If a material having good air permeability is used, the effect of improving air permeability is great even if the area is small. In addition, as a difference in air permeability, the air permeability of the first part is preferably twice or more than the air permeability of the second part. Further, the area of the first portion that improves air permeability is preferably 10 square centimeters or more, and more preferably 40 square centimeters or more. The area of the second portion is preferably 5 square centimeters or more, and more preferably 10 square centimeters or more.
[0024]
  The present invention can be applied to various items as long as it is a garment that adheres to the buttocks and covers at least the buttocks.The present inventionThe buttock-covered garment includes briefs, shorts, girdle, high waist girdle, sports bottom, spats, and body suit. Thus, there is an advantage that versatility is extremely high.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, an example of a girdle will be described as an embodiment of a buttock-covering garment according to the present invention with reference to the drawings.
[0026]
  As shown in FIGS. 1 (a) to 1 (c), the girdle 10 includes a front body 12, a pair of left and right leg portions and heel portions 14a and 14b, a crotch portion 16 and a sacral portion 18, and these fabrics are sewn together. Has been.
[0027]
  What is characteristic in the present embodiment is that in the girdle 10, a fabric having a standard or lower breathability (for example, a power net) is used for the legs and the heel portions 14 a and 14 b, and the fabric is used for the crotch portion 16 and the sacral portion 18. By using a fabric having better air permeability (for example, mesh cloth), the air permeability of the crotch portion 16 and the sacral portion 18 is relatively better than the air permeability of the leg portions and the heel portions 14a and 14b. That is.
[0028]
  As a method of providing a difference in air permeability, a method of joining a plurality of fabrics having different air permeability as described above (so-called cut and saw) may be employed, or the knitting structure is changed in one fabric. Thus, a method may be employed in which the fabric is cut and stitched so as to provide a difference in air permeability so that a knitted tissue region having different air permeability becomes a required portion. In the following, adoptable methods will be described.
[0029]
  As a method of joining a plurality of fabrics, a method of applying a warp knitted material such as mesh power net, pattern power net, raschel lace, double raschel, etc. A method of applying a circular knitted material having a mesh-like structure or a needle-punched structure to the crotch part 16 and the sacrum part 18 can be employed. A method using a satin power net, a two-weight ricott, a two-way raschel, a circular knitted knit, or the like can be employed for the body material of the legs and the collars 14a and 14b.
[0030]
  On the other hand, as a method of providing a difference in air permeability by tailoring one sheet, a method of switching a knitted structure, a post-processing by resin processing, a post-processing by opal processing, or the like can be adopted. Among them, the method of changing the knitting structure to form a part having different air permeability in one piece of fabric includes knitting structure change by a single raschel machine, knitting structure change by a circular knitting machine, knitting structure change by a double raschel machine, double Examples include knitting structure change by a knit machine. Examples of the post-processing by the resin processing include processing such as reducing air permeability by performing processing such as bonding or welding the resin to the fabric. As post-processing by opal processing, the process of forming a part with good air permeability by melting and thinning a required part of cloth is mentioned.
[0031]
  Next, the effect | action of this embodiment is demonstrated using FIG. When wearing the girdle 10,RuptureA vertically long space 30 (see FIG. 2 (d)) is formed along the side, but as the distance between the body 20 and the girdle 10 changes due to leg movement during walking, the size of the space 30 also changes. . In the girdle 10, the air permeability of the sacral portion 18 and the crotch portion 16 is improved compared to the air permeability of the leg portions and the heel portions 14 a and 14 b, so that when the size of the space 30 changes with the movement of the leg portions during walking, the relative In addition, the leg portions and the heel portions 14a and 14b having poor air permeability become the pump portion, and the sacrum portion 18 and the crotch portion 16 having relatively good air permeability become the air intake / exhaust portions. appear.
[0032]
  That is, when walking, the state where one foot comes out ahead of the other foot as shown in FIG. 2 (a) and the state where both feet are aligned as shown in FIG. 2 (c) are repeated. Among these, when one foot comes forward as shown in FIG. 2 (a), the space 30 narrows as shown in FIG. 2 (b), so that the air accumulated in the space 30 is communicated upward. And it flows out to the crotch part 16 connected below, and is discharged | emitted from the sacrum part 18 and the crotch part 16 outside. When both feet are aligned as shown in FIG. 2C, the space 30 is expanded as shown in FIG. 2D, so that outside air is sucked from the sacral portion 18 and the crotch portion 16 and flows into the space 30. For this reason, while walkingRuptureThe discharge of air from the space 30 and the suction of air are repeated.
[0033]
  Thus, with the walking movement at the time of wearing, the sacral part 18 and the crotch part 16 andRuptureSince an air flow is generated between the space 30 and the space 30, it is possible to eliminate the feeling of stuffiness and heat accumulation in these parts. In addition, it can be realized with a structure that provides a difference in breathability of the required part, and other parts may be used in combination with a structure for hip-up and stomach-holding, and parts that do not require breathability By using a low stretch fabric such as a satin power net, it is possible to retain the shaping function such as the hips that the girdle has conventionally.
[0034]
  Hereinafter, various modified examples of portions having good air permeability of the sacral portion 18 and the crotch portion 16 (hereinafter referred to as “air permeability good portion”) will be described.
[0035]
  First, the breathable portion provided in the sacrum 18 is as shown in FIG.RuptureIt is good also as the area | region 18A of the substantially isosceles triangle which reached the upper end near the upper end vicinity of FIG. 3, or as shown in FIG.3 (b).RuptureIt is good also as a rhombus area | region (what is called a sacral rhombus area | region) 18B which used the vicinity of the upper end of 1 as one vertex. Also, as shown in FIG.Rupture10C may be a semicircular region 18C extending upward from the vicinity of the upper end of FIG. 10B, or may be a triangular region 18D having a long base contacting the sacrum and waist as shown in FIG. 10B. ) As shown in FIG. Further, the shape of the good air permeability portion provided in the sacrum portion 18 may be an asymmetric shape such as a floral pattern.
[0036]
  Further, various shapes shown in FIG. 4 can be adopted for the air permeability good portion provided in the crotch portion 16. In addition, in each figure of FIG.RuptureThis is the side communicating with the space 30 (see FIG. 2D).
[0037]
  That is, as shown in FIG.RuptureA substantially pentagonal shape including a substantially isosceles triangular region 16A communicating with the space 30 (see FIG. 2D), and the tip of the region 16A is rounded, as shown in FIG. 4B. ) And a substantially pentagonal shape with the tip of the region 16B pointed, as shown in FIG. 4 (c), a substantially quadrilateral shape excluding the region 16A from the substantially pentagonal shape of FIG. 4 (a), and FIG. FIG. 4 (a) is the same as FIG. 4 (a), but the area 16C is substantially semicircular, and FIG. 4 (e) is the only area 16A of FIG. A mode in which only the region 16B in FIG. 4B is the air permeable portion as shown in FIG. 4 (f), and a mode in which only the region 16C in FIG. 4D is the air permeable portion as shown in FIG. Various aspects can be adopted. Moreover, the shape of the air permeability favorable part provided in the crotch part 16 may be an asymmetrical shape such as a floral pattern.
[0038]
  Alternatively, a single mesh crotch cloth may be applied to the entire crotch portion, and a cloth such as cotton may be further attached to the inside of the crotch cloth.
[0039]
  By the way, in this embodiment, the part from which the air permeability differs can be provided by using the cloth which knitted the air permeability part and the air permeability part in one sheet by a single jacquard raschel knitted fabric. . The method will be described with reference to FIG.
[0040]
  In one single jacquard raschel knitted fabric 100 shown in FIG. 11, the knitting structure is switched in a semicircular arc shape to form regions 100A and 100B. Of these, the region 100B has a satin knitting structure. The satin-like knitted structure is relatively tightly knitted and has a low air permeability. On the other hand, since it has a low stretchability, the right and left best bloom 104 of the long girdle is cut from this region 100B and used. In this way, the long girdle is formed at the best time with low elasticity, so that it can have a body shape correcting function.
[0041]
  One region 100A is a mesh-knitted structure. The mesh-like knitting structure is coarser and has better air permeability than the satin-like knitting structure. The right and left best seasons 104 are cut so that a portion that improves the air permeability above the long girdle comes into contact with the region 100A of the mesh-like knitting structure. The crotch cloth 102 used for the crotch portion is also cut from the region 100A.
[0042]
  A long girdle 10 as shown in FIG. 1 is obtained by sewing a total of four pairs of the left and right best seasons 104, the crotch cloth 102, and an abdominal cloth (not shown). In this case, the sacral portion 18 is a substantially isosceles triangle, but the two equilateral portions are curved inwardly.
[0043]
  Further, in the present embodiment, as a further application example of a single jacquard raschel knitted fabric in which different tightening force portions and different breathable portions can be knitted in one piece of fabric, the single jacquard raschel knitted fabric is used as a short girdle and An example applied to a long girdle will be described.
[0044]
  The point of this method will be explained by using an example of a short girdle. A large jacquard pattern having curved portions as shown in regions S1, S3, and S4 shown in FIG. Separate the sex parts and further change the tightening force in the areas SA, SB, SC by switching the elastic yarn linearly in the band-shaped areas SA, SB, SC in the knitting direction of the fabric (arrow P direction) It is characterized by. Since a girdle is produced using a single jacquard russell knitted fabric having such characteristics, it is possible to eliminate the level difference of the stitching line caused by stitching two pieces of fabric from the hip line, and it is possible to reduce the number of stitches. The labor of sewing can be reduced and the production efficiency can be improved.
[0045]
  Hereinafter, an application example to the short girdle and an application example to the long girdle will be described in order. First, FIG. 12A regarding the application example to the short girdle is a view of the application example to the short girdle as viewed obliquely from the rear, FIG. 12B illustrates the view from the front, and FIG. The state before cutting is shown.
[0046]
  In FIG. 13, the region S3 is a strong satin knitting structure, the regions S1 and S4 are mesh knitting structures, the regions S2 and S5 are weak satin knitting structures, and the line C1 represents a cutting line between the left and right bodies. The areas S1 to S5 inside the cutting line C1 correspond to the areas S1 to S5 in FIG.
[0047]
  In FIGS. 12 (a) and 12 (b), the region S3 corresponds to a belt-like region having a width of about 7 cm at the lower part of the hip curved from the lower part of the hip to the waist. As a result, it has a hip-up effect.
[0048]
  In addition, the region S4 isRuptureIn the lower part, the region S1 isRuptureThese regions S4 and S1 correspond to the upper portions, respectively, and have a coarse mesh knitting structure, and the air permeability is improved compared to the other portions of the strong satin knitting structure and the weak satin knitting structure. As a result, as described above,RuptureUpper region S1 andRuptureBetween the lower area | region S4, air distribute | circulates and the highly breathable girdle which does not feel stuffiness is implement | achieved. As an example, the region S4 has a semi-cylindrical shape with a width of 9 cm and a height of 3.5 cm, and the region S1 has an isosceles triangle shape with a base of 15 cm and a height of 9 cm.
[0049]
  The regions S2 and S5 have a weak satin knitting structure, and are stretched better than the region S3 having a strong satin knitting structure so that the hips can follow the swelling of the hips.
[0050]
  On the other hand, in FIG. 13, the tightening force by the elastic yarn is switched along the knitting direction (arrow P direction) of the fabric, and the tightening force of the region SC is the strongest. Has been. As an example, one elastic thread of 200 dtex (hereinafter referred to as “dtex”) is inserted into the area SA, and two 200 dtex elastic threads are inserted into the area SB having a width of 4 cm corresponding to the lower part of the hip. ing. Further, three 200 dtex elastic yarns are inserted into a region SC having a width of 3.5 cm corresponding to the hem line.
[0051]
  Thereby, in the lower hip part, a region S3 of a strong satin jacquard knitting structure having a strong tightening force of about 7 cm, a region SB of 4 cm width in which two elastic yarns are inserted, and an elastic yarn 3 below the region SB. Since the inserted region SC having a width of 3.5 cm substantially overlaps, a portion having the strongest tightening force is formed, and the hip-up effect is increased.
[0052]
  Next, an application example to the long girdle will be described. Fig. 14 (a) shows an example of application to the long girdle from an oblique rear side, Fig. 14 (b) shows a diagram seen from the front, and Fig. 15 shows a state before the knitted fabric is cut.
[0053]
  In FIG. 15, the region L3 is a strong satin knitting structure, the regions L1 and L4 are mesh knitting structures, the regions L2 and L5 are weak satin knitting structures, and the line C2 represents a cutting line between the left and right bodies. The regions L1 to L5 inside the cutting line C2 correspond to the regions L1 to L5 in FIG.
[0054]
  In FIGS. 14 (a) and 14 (b), the region L3 corresponds to a belt-like region having a width of about 7 cm at the lower part of the hip curved from the lower part of the hip to the waist. As a result, it has a hip-up effect.
[0055]
  In addition, the region L4 isRuptureIn the lower part, the region L1 isRuptureThese regions L4 and L1 correspond to the upper portions, respectively, and have a coarse mesh knitting structure, and the air permeability is improved as compared with other strong satin knitting structures and weak satin knitting structures. As a result, as described above,RuptureThe upper region L1 andRuptureBetween the lower area | region L4, air distribute | circulates and the highly breathable girdle which does not feel stuffiness is implement | achieved. As an example, the region L4 has a kamaboko shape with a width of 5 cm and a height of 4.5 cm, and the region L1 has an isosceles triangle shape with a base of 16 cm and a height of 8 cm.
[0056]
  The regions L2 and L5 have a weak satin knitting structure, and are stretched better than the region L3 having a strong satin knitting structure so that the hips can follow the swelling of the hips.
[0057]
  On the other hand, in FIG. 15, the tightening force by the elastic yarn is switched along the knitting direction of the fabric (the direction of the arrow Q), and the tightening force of the region LC is the strongest. Has been. As an example, one 200 dtex elastic thread is inserted into the area LA, and two 200 dtex elastic threads are inserted into the area LB having a width of 18 cm corresponding to the thigh from the lower hip. Yes. This means that every wale is inserted as 2, 1, 1, 2, 1, 1, 2, 1, 1,. In addition, two 200 dtex elastic yarns are inserted into a region LC having a width of 3 cm corresponding to the hem line.
[0058]
  Thereby, in the lower hip part, the area L3 of the strong satin jacquard knitting structure having a strong tightening force of about 7 cm and the area LB in which two elastic yarns are inserted are substantially overlapped. Therefore, a portion having a strong tightening force is formed, and the hip-up effect is increased.
[0059]
  13 and 15 show the best time to apply to the hip for both short and long.RuptureIt is sutured with. Separately, one abdominal cloth and one crotch cloth are stitched to form a girdle.
[0060]
  Although the example of the girdle has been described in the present embodiment, the present invention can be applied to various items as long as it is a garment that is in close contact with the buttocks and covers at least the buttocks. For example, a high waist type girdle 40 as shown in FIG. 5, a shorts 50 as shown in FIG. 6, a brief 60 as shown in FIG. 7, a body suit 70 as shown in FIG. 8, and other sports bottoms and spats. The air flow during walking due to the same phenomenon as the above can be generated by relatively increasing the air permeability of the sacrum and crotch parts (the shaded area in each figure). ,RuptureThe feeling of stuffiness and heat can be eliminated.
[0061]
  The present invention can also be applied to stockings and tights. By switching the circular knitting organization,RuptureThe upper and lower portions can be realized by using a knitted structure having better air permeability than other portions.
[0062]
  Also, when applying the present invention, the waist cloth,RuptureAs with the upper and lower portions, a mesh cloth with good air permeability may be adopted, and the stuffiness can be further reduced.
[0063]
【The invention's effect】
  As described above, according to the present invention, the air permeability of the sacral portion communicating with the upper portion and the crotch portion communicating with the lower portion with respect to the vertically long space formed in the rupture portion at the rear center of the heel portion when worn, Since the air permeability of the cracked part and the left and right parts is improved across the cracked part, the air flow to the cracked part occurs naturally, and during walking movement, the walking action is caused by the phenomenon of sniffing. Along with this, air flows in the spaces of the sacrum, crotch, and ruptured portions, and the stuffiness and heat accumulation in these parts can be eliminated.
In particular, according to the present invention, while the air permeability of both the first and second locations is improved, the air permeability of the first location is better than the air permeability of the second location between them. Therefore, the ventilation from the lower side to the upper side is promoted in the space of the cracked portion, and the heat radiation at the first location is promoted. For example, the wearer can easily feel cool.
