Description

  The present invention relates to bedding such as mattresses, mattresses, and pillows in consideration of dispersion of body pressure, and a method for manufacturing the bedding, bedclothes such as mattresses and pillows that can be adjusted in height, and bedding covers such as mattress covers and pillow covers.

  In response to the recent increase in health consciousness, interest in bedding for mattresses such as mattresses, which occupy an important position in bedding, has increased greatly. It is well known that bed makers have started to propose bed mats that conform to the shape of the human body. Such a bed mat is intended to obtain an optimal sleeping comfort by combining a spring having different wire diameters with a cushioning property in accordance with the shape of the human body.

  On the other hand, various beddings are sold by various companies regarding bedding, but it is clear that the most important point of pillows is to optimize and stabilize the sleeping posture, that is, to ensure a natural sleeping posture. The natural sleeping posture is considered to be a posture in which a human stands as it is. In such a sleeping posture, a large part of the body is supported by a skeletal part that protrudes from the back of the body, such as the hipbone and scapula. In general, the back of a man protrudes and the waist of a woman protrudes, so the sleeping posture differs depending on the body shape of the man and woman.

  However, not all the residents are bed users, and the above-mentioned bed mat cannot be used when sleeping on a floor such as tatami mats, flooring or carpets directly.

  In addition, the existing mattresses and bed mats are only able to harden the central part by increasing the number of fillers, etc., and the actual situation is that they are not able to respond precisely to differences in physique between men and women or differences in physique due to individual differences. It is.

  Therefore, the present invention can be used on floors such as tatami mats, flooring, carpets, etc., and bedding such as mattresses, mattresses, pillows, and the like, which are particularly excellent in durability and body pressure dispersibility, and a manufacturing method thereof, It is another object of the present invention to provide a bedding such as a mattress, mattress, and pillow that can be adjusted in height, and a bedding cover such as a mattress cover and a pillow cover.

  The bedding according to the present invention is a bedding equipped with an elastic body with protrusions having large, medium, and small areas on the surface, and the protrusion on the surface of the elastic body changes in the protrusion amount of the uneven shape on the back of the body. And the change in the area of the protrusion is reversed, and the change in the load distribution exerted on the bedding by the back in the body lying state coincides with the change in the area of the protrusion. It is a feature. In this case, “arrangement so that the change in the protrusion amount of the concavo-convex shape on the back of the body is opposite to the change in the area of the protrusion” means that the protrusion amount of the concavo-convex shape on the back of the body is large Means that a protrusion having a small area is disposed, and if the protrusion amount of the concavo-convex shape on the back of the body is small, a protrusion having a large area is disposed. In addition, “the arrangement in which the change in the load distribution exerted on the bedding by the back surface in the body lying state coincides with the change in the area of the protrusion” means that the load distribution exerted on the bedding by the back surface in the body lying state In the case of large, it means that a projection having a large area is arranged, and in the case where the load distribution exerted on the bedding by the back in the lying state of the body is small, the projection having a small area is arranged.

  By configuring as described above, a portion having a relatively large protrusion on the back surface of the body has a relatively small protrusion on the surface of the elastic body, so that the protrusion sinks deep according to the protrusion. . A portion having a relatively small protrusion on the back surface of the body has a relatively small protrusion on the surface of the elastic body, and therefore sinks shallowly according to the protrusion. In addition, a portion where the load exerted on the bedding by the back surface in the lying state of the body is shallow because the protrusion having a relatively large area is arranged on the surface of the elastic body. The portion where the load on the bedding is exerted on the bedding by the back surface of the body lying on its back is submerged shallowly because a protrusion having a relatively small area is arranged on the surface of the elastic body.

  In addition, the method for manufacturing the bedding according to the present invention includes an elastic structure in which protrusions having large, medium, and small areas are arranged on the surface according to the uneven shape of the back of the body and / or the load distribution of the back in the lying state of the body on the bedding. The bedding is manufactured by interior decoration of the body.

  Furthermore, the unevenness of the back of the body and / or the load distribution exerted on the bedding by the back of the body in a lying state is measured by a measuring instrument, and an elastic body is manufactured based on the measurement result. You may make it produce bedding.

  In addition, the measuring device measures the uneven shape of the back surface of the body and / or the load distribution exerted on the bedding by the back surface of the body in the lying state, manufactures an elastic body based on the measurement result, and installs the manufactured elastic body. You may employ | adopt the sales method of bedding which manufactures bedding and provides the manufactured bedding to a customer.

  Furthermore, the bedding or bedding cover according to the present invention has a plurality of bag portions extending in the lateral direction of the bedding or bedding cover on the back side of the bedding, and a raising plate for partially raising the bulk of the bedding on the bag portion. It is characterized in that it can be stored.

  If comprised in this way, it will become possible to adjust the height of bedding partially.

  Furthermore, the bedding is provided with an elastic body having protrusions with large, medium, and small areas on the surface, and the protrusion on the surface of the elastic body has a change in the protrusion amount of the uneven shape on the back of the body and a change in the area of the protrusion. Are arranged so that the change in the load distribution in the lying state of the body coincides with the change in the area of the protrusions, and a plurality of lateral directions of the bedding are provided in the lower part of the bedding. A bag portion is formed, and a raised plate for partially raising the volume of the bedding can be accommodated.

  If comprised in this way, since the protrusion with a comparatively small area is arranged on the surface of an elastic body in the location where the protrusion amount of the uneven | corrugated shape of a body back is comparatively large, it will sink deeply according to the protrusion amount. A portion having a relatively small protrusion on the back surface of the body has a relatively small protrusion on the surface of the elastic body, and therefore sinks shallowly according to the protrusion. In addition, a portion where the load exerted on the bedding by the back surface in the lying state of the body is shallow because the protrusion having a relatively large area is arranged on the surface of the elastic body. The portion where the load on the bedding is exerted on the bedding by the back surface of the body lying on its back is submerged shallowly because a protrusion having a relatively small area is arranged on the surface of the elastic body. In addition, the height of the bedding can be partially adjusted.

  The bedding according to the present invention is a bedding equipped with an elastic body with protrusions having large, medium, and small areas on the surface, and the protrusion on the surface of the elastic body changes in the protrusion amount of the uneven shape on the back of the body. And the change in the area of the protrusion are reversed, and the change in the load distribution exerted on the bedding by the back in the body lying state coincides with the change in the area of the protrusion. , Where the protrusion on the back of the body has a relatively large protruding amount, a protrusion with a relatively small area is arranged on the surface of the elastic body, so that the body pressure is dispersed because it can sink deeply according to the protruding amount There is an effect and there is a sense of stability. In areas where the protrusions on the back of the body have relatively small protrusions, protrusions with a relatively large area are placed on the surface of the elastic body. Is good. In addition, in areas where the back of the body is lying on the bedding, protrusions with a relatively large area are arranged on the surface of the elastic body, so the sinking is shallow despite the large load. Is securely supported, and the durability against the sag of the elastic body is improved. In the portion where the load on the bedding is exerted on the bedding by the back surface of the body lying down, a protrusion having a relatively small area is arranged on the surface of the elastic body, but since the load is small, it sinks shallowly and has a soft feeling on the body.

  In addition, the method for manufacturing the bedding according to the present invention includes an elastic structure in which protrusions having large, medium, and small areas are arranged on the surface according to the uneven shape of the back of the body and / or the load distribution on the back of the body in the lying state of the body. When a bedding is manufactured with a body inside, a bedding excellent in durability and pressure dispersion according to a difference in physique due to gender differences and a difference in physique due to individual differences can be manufactured.

  Furthermore, the unevenness of the back of the body and / or the load distribution exerted on the bedding by the back of the body in a lying state is measured by a measuring instrument, and an elastic body is manufactured based on the measurement result. You may make it produce bedding.

  In addition, the measuring device measures the uneven shape of the back surface of the body and / or the load distribution exerted on the bedding by the back surface of the body in the lying state, manufactures an elastic body based on the measurement result, and installs the manufactured elastic body. By adopting a bedding sales method that manufactures bedding and provides the manufactured bedding to customers, it provides bedding with excellent durability and pressure-resistant dispersibility according to differences in physique due to gender differences and physique differences due to individual differences it can.

  Furthermore, the bedding or bedding cover according to the present invention has a plurality of bag portions extending in the lateral direction of the bedding or bedding cover on the back side of the bedding, and a raising plate for partially raising the bulk of the bedding on the bag portion. When configured to be stowable, the height of the bedding can be adjusted. That is, if the raising plate is stored in the bag portion as necessary, the bedding can be partially made bulky. Therefore, when the bulk of the bedding on which the body's feet are placed is made bulky, or when the central part of the bedding on which the back of the body is placed becomes bulky, the volume is lowered. If the raised plate is stored in the bag portion of the portion, it is possible to raise the sag portion.

  Furthermore, the bedding is provided with an elastic body having protrusions with large, medium, and small areas on the surface, and the protrusion on the surface of the elastic body has a change in the protrusion amount of the uneven shape on the back of the body and a change in the area of the protrusion. Are arranged so that the change in the load distribution in the lying state of the body coincides with the change in the area of the protrusions, and a plurality of lateral directions of the bedding are provided in the lower part of the bedding. When the bag portion is formed and a raised plate for partially raising the volume of the bedding can be accommodated, the area where the protrusion amount of the uneven shape on the back of the body is relatively large has an area on the surface of the elastic body. Since relatively small protrusions are arranged, it is possible to sink deeply according to the amount of protrusion, so that there is an effect of dispersing body pressure and there is a sense of stability. In areas where the protrusions on the back of the body have relatively small protrusions, protrusions with a relatively large area are placed on the surface of the elastic body. Is good. In addition, in areas where the back of the body is lying on the bedding, protrusions with a relatively large area are arranged on the surface of the elastic body, so the sinking is shallow despite the large load. Is securely supported, and the durability against the sag of the elastic body is improved. In the portion where the load on the bedding is exerted on the bedding by the back surface of the body lying down, a protrusion having a relatively small area is arranged on the surface of the elastic body, but since the load is small, it sinks shallowly and has a soft feeling on the body. In addition, the height of the bedding can be adjusted. That is, if the raising plate is stored in the bag portion as necessary, the bedding can be partially made bulky. Therefore, when the bulk of the bedding on which the body's feet are placed is made bulky, or when the central part of the bedding on which the back of the body is placed becomes bulky, the volume is lowered. If the raised plate is stored in the bag portion of the portion, it is possible to raise the sag portion.

  The measuring device measures the uneven shape of the back of the body and / or the load distribution exerted on the bedding by the back in the lying state of the body, manufactures an elastic body based on the measurement result, and lays the manufactured elastic body on the bedding. As a measuring instrument used for manufacturing, along with the height and weight scale for measuring the height and weight, a detection rod with a sensor that moves forward and backward according to the uneven shape of the back of the body is moved up and down on the back of the body. The bevel may be manufactured by using a measuring device that electrically measures the concavo-convex shape and manufacturing an elastic body based on the measurement result. In addition, three types of measurement elastic bodies with predetermined widths, each having protrusions with large, medium, and small areas on the surface, are prepared, and these three types of measurement elastic bodies are combined to perform on-site measurement. The bedding may be manufactured by manufacturing an elastic body based on the result.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a partial perspective view of a urethane foam for measurement having a predetermined width formed with two projections having a large area on the surface, and FIG. 2 is a urethane for measurement having a predetermined width having three protrusions having a medium area on the surface. FIG. 3 is a partial perspective view of a foam, and FIG. 3 is a partial perspective view of a urethane foam for measurement having a predetermined width formed with four projections having a small area on the surface. FIG. FIG. 5 is a table showing the correlation with the size of the area of the protrusion formed on the foam, FIG. 5 is a perspective view of the urethane foam formed based on the measurement result, and FIG. 6 is a sink of the urethane foam shown in FIG. It is a schematic diagram which shows a state.

  In FIG. 1, A is a urethane foam for measurement having a predetermined width with a protrusion having a large area on the surface. Specifically, the center is constricted on a base part A1 having a width of 140 mm and a length of 1000 mm, the upper part is swollen, and the upper face is Two rows of mushroom-shaped protrusions A2 having a substantially square shape and an area of about 60 mm × 60 mm are formed. B is a urethane foam for measurement having a predetermined width on the surface with a projection having a medium area. Specifically, the center is constricted on the base part B1 having a width of 140 mm and a length of 1000 mm, the upper part is swollen, the upper part is rectangular and the area is rectangular. Three rows of mushroom-like protrusions B2 of about 40 mm × 60 mm are formed. C is a urethane foam for measurement having a predetermined width on the surface with a projection having a small area. The center is constricted on the base part C1 having a width of 140 mm, the upper part is swollen, the upper face is rectangular, and the area is about 30 mm × 60 mm. The mushroom-like projections C2 are formed in three rows. The reason why the width of each measurement urethane foam was 140 mm was that the length of the urethane foam used as a bedding was 2100 mm, and this was divided into 15 equal parts to 140 mm. The length of each measurement urethane foam was set to 1000 mm because the width of the urethane foam serving as a bedding was 1000 mm. As for the shape of the protrusion having a large, medium and small difference in area on the surface, a mushroom shape was adopted in this embodiment, but the shape is not limited to this, and a flat shape such as a rectangular parallelepiped or a cube is used. Any shape such as a thing, a mountain shape, or a trapezoid shape may be used, and any shape that protrudes from the base portion may be used.

  The three types of urethane foams A, B, and C for measurement are used in combination according to the uneven shape of the back surface of the body and the load distribution exerted on the bedding by the back surface of the body in the lying state. As a method of combination, the protrusion on the surface of the urethane foam is arranged so that the change in the protrusion amount of the concavo-convex shape on the back of the body is opposite to the change in the area of the protrusion, and the back in the body lying state is It arrange | positions so that the change of the load distribution which acts on bedding and the change of the area of the said protrusion may correspond. Specific examples of this correlation are shown in Table 1.

  When arranged as described above, a portion having a relatively large protrusion on the back of the body has a relatively small protrusion on the surface of the urethane foam, so that the protrusion may sink deep depending on the protrusion. Since it can, it has the effect of dispersing body pressure and has a sense of stability. When the protrusion on the back of the body has a relatively small protrusion, the urethane foam surface has a protrusion with a relatively large area, so it sinks shallowly according to the protrusion and is smooth and comfortable to move. Is good. Also, when the back of the body is lying on the back, the area where the load on the bedding is large has a relatively large area on the surface of the urethane foam, so the sinking is shallow despite the large load. It has a sense of stability by supporting it reliably, and the durability against urethane foam sag is improved. In the portion where the back surface of the body in the lying state exerts a small load on the bedding, a protrusion having a relatively small area is arranged on the surface of the urethane foam, but since the load is small, it sinks shallowly and has a soft feeling on the body.

  Based on the above theory, a specific example in which the three types of measurement urethane foams A, B, and C are actually combined and arranged in accordance with the shape of the body and the load distribution exerted on the bedding by the back of the body in the lying state is shown in FIG. Shown in The actual sinking amount in the state where the urethane foams A, B, and C for measurement shown in FIG. 5 are arranged is represented by the schematic diagram of FIG. In addition, if it tries on what comprised the urethane foam for measurement A, B, and C in this way, and there is no malfunction, it will be integrated or divided into three according to the arrangement of the urethane foam for measurement A, B, and C. The finished product of urethane foam will be manufactured.

  In FIG. 6, for convenience, the measurement urethane foam is arranged at addresses 1 to 15 from the head end side of the body. Measuring urethane foam A with large protrusions was placed at addresses 1 and 15 at both the left and right ends, and was configured to withstand even when the entire urethane foam was lifted or pulled. Pillows are used together at addresses 2 to 4 where the head and neck of the body correspond, and there is no need to consider the protrusion of the body, and the load increases from the top of the head to the neck. Urethane foam C, urethane foam B with protrusions inside, and urethane foam A with large protrusions were disposed. Since the number 5 and the number 6 correspond to the back part of the body, the protrusions are large, and the parts to which a large load is applied, the urethane foam B having the protrusions therein was disposed. No. 7 corresponds to the waist of the body, has a small protrusion, and is a part where a large load is applied. Therefore, urethane foam A having a large protrusion was disposed. Since No. 8 and No. 9 correspond to the buttocks of the body, have large protrusions, and are portions where a large load is applied, the urethane foam B having protrusions therein was disposed. Nos. 10 and 11 correspond to the thighs of the body, have few protrusions, and are portions to which a large load is applied. Therefore, urethane foam A having a large protrusion was disposed. Since No. 12 corresponds to the shin part of the body and has a small protrusion and a small load is applied, urethane foam B with a protrusion inside is arranged. No. 13 corresponds to the shin part of the body, has a small protrusion, and hardly receives a load. Therefore, urethane foam C having a small protrusion was arranged. No. 14 corresponds to the buttocks of the body, is slightly protruding, and is a portion on which a small load is applied. Therefore, urethane foam C having a small protrusion was disposed.

  In addition, the combination arrangement of measurement urethane foams A, B, and C as described above is to measure the height and weight of a test subject who is a customer, and test the measurement urethane foams A, B, and C by predicting from the shape of the body. After being combined, the test subjects try on the combined measurement urethane foams A, B, and C, make actual measurements, adjust them, and give the final measurement results. Also, the height and weight of the subject, together with the height and weight scale, are moved up and down on the back of the body in accordance with the height of the unevenness on the back of the body. Using a measuring device to measure, based on the measurement results, after the test urethane foams A, B, C are combined on a trial basis, the test subjects try on the combined urethane foams A, B, C for measurement. Actual measurement and adjustment may be performed to obtain a final measurement result.

  Based on the measurement result obtained as described above, a urethane foam is manufactured to manufacture a bedding. If it does so, the manufactured bedding will be excellent in the durability and pressure | voltage resistant dispersibility according to the difference in the physique by the gender difference, and the difference in the physique by the individual difference. In addition, when such measurement results are organized and stored as customer data, when the customer newly purchases and uses bedding, the sales side can estimate the status of the previous sleeping environment, It is convenient because it helps advice and the sale of bedding accurately.

  In this embodiment, an example in which urethane foam is used as an elastic body or a measurement elastic body has been described. However, foams such as PE, PP, EVA and other elastic elastomers, nonwoven fabrics and other fiber laminated assemblies The body may be used.

In the present embodiment, the length of the urethane foam D is set to 2100 mm, and a bag portion having a width of 100 mm is formed by dividing the length into 21 equal parts. This bedding is completed by enclosing the whole with a bedding cover. In FIG. 8, F is a raising plate for partially raising the bulk of the urethane foam D, and a small bag f is provided at the tip of the raising plate F. G is a press-fit rod for inserting the raised plate F into the bag portions E1 to E21.

  And the raising board F is inserted in the bag parts E1-E21 formed in the back side of the urethane foam D shown in FIG. An example of its use is shown in FIGS.

  The usage example shown in FIG. 9 shows a state in which the part of the bedding corresponding to the leg part of the body is raised. Standing people often raise their bedding in the area corresponding to the legs of the body to eliminate fatigue on their feet, and if such a need arises, they are equivalent to the legs of the body The necessity is satisfied by inserting the raised plate F into the four bag portions E18 to E21 which are the portions to be performed.

  The usage example shown in FIG. 10 shows the state which raises the bedding of the center part of the urethane foam D. FIG. When there is a sag in the central part where the load is applied due to the aging of the urethane foam D, and there is a need to increase the amount of bulk reduction due to the sag, there are five places in the central part of the urethane foam D. The necessity is satisfy | filled by inserting the raising board F in the bag parts E9-E13.

  In this embodiment, an example in which urethane foam is used as the raising plate has been described. However, foams such as PE, PP, EVA and other elastic elastomers, nonwoven fabrics and other fiber laminated assemblies, air mats and the like are used. In addition to the elastic material, a hard material may be adopted as long as it does not affect the body pressure dispersion effect on the surface of the urethane foam D. In short, any material can be used as long as the urethane foam D is raised. May be used.
