Description

The present invention relates to bedding such as mattresses, mattresses, and pillows in consideration of body pressure dispersion and a method for manufacturing the same.

  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 residents are bed users, and when sleeping on a floor such as tatami mats, flooring, or carpet, etc., with the existing mattresses and mattresses, cushioning that matches the shape of the human body It was not possible to deal with this.

In addition, with the existing mattresses and mattresses, it is only possible to harden the central part by increasing the filler, etc., and it is actually impossible to deal with differences in physique between men and women or physique due to individual differences. is there.

Therefore, the present invention provides a bedding such as a mattress, mattress, and pillow that can be used on a floor such as a tatami mat, flooring, or carpet , and has a cushioning property that conforms to the shape of the human body, and a manufacturing method thereof. The purpose is to provide .

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. The area of the protrusion does not change or agrees with the change in the load exerted on the bedding by the back surface of the body lying on the back. it is characterized in that it has arranged to. As used herein, the “arrangement is such that the area of the protrusions does not change or changes inversely with respect to the change in the protrusion amount of the concavo-convex shape on the back of the body” as shown in the table of FIG. When the protrusion amount of the concavo-convex shape on the back surface decreases, the area of the protrusion does not change or increases, and when the protrusion amount of the concavo-convex shape on the back surface increases, the area of the protrusion increases. This means that it is arranged so that it does not change or decreases.For example , when the protrusion amount of the uneven shape on the back surface of the body is large, a protrusion with a small protrusion area is arranged, and the protrusion amount of the uneven shape on the back surface of the body When is small, it means that a projection having a large area is arranged. In addition, “the arrangement is such that the area of the protrusion does not change or coincides with the change in the load exerted on the bedding by the back surface in the body lying state” as shown in the table of FIG. When the load on the bedding on the back in the state decreases, it means that the area of the protrusion does not change or decreases, for example , the load on the bedding by the back on the body lying down is large. In this case, a projection having a large area is disposed, and when the load exerted on the bedding by the back in a lying state of the body is small, a projection having a small area is disposed. Furthermore, since the area of the protrusion is configured so as to have a large, medium, and small difference as shown in FIGS. 1 to 3, when the same load is applied to each protrusion, the protrusion is changed as the area of the protrusion changes from large to small. Since the weight per unit area increases, the amount of protrusion sinking increases.
By configuring as described above, as shown in the table of FIG. 4, when the protrusion amount of the concavo-convex shape on the back surface of the body is relatively large, when the load on the bedding by the back surface of the body lying on the bedding is small, Since a protrusion having a relatively small area is arranged on the surface of the elastic body, it sinks deep according to the amount of protrusion, so that a cushioning property corresponding to the shape of the human body can be obtained . To prevent this from happening, the surface of the elastic body should be placed on the surface of the elastic body in order to prevent the sinking from deepening as the load applied to the bedding by the back surface of the body lying down is large. If the protrusions are arranged so that the area of the protrusions increases, cushioning properties that match the shape of the human body can be obtained. In addition, if a protrusion with a large protrusion area is placed at a location where the protrusion on the back of the body has a relatively large protrusion amount, the cushioning property conforms to the shape of the human body by becoming shallower than the sinking according to the protrusion amount. It will be damaged.
When the protrusion on the back of the body is relatively small, the protrusion on the elastic body has a relatively large area when the back of the body is on the bedding and the load on the bedding is large. Since it sinks shallowly according to the amount of protrusion , cushioning properties that match the shape of the human body can be obtained . To prevent this, the surface of the elastic body has a surface where the sinking becomes shallower as the load on the bedding by the back surface of the body lying on the back is reduced. If the protrusions are arranged so that the area of the protrusions decreases, cushioning properties that match the shape of the human body can be obtained. In addition, if a projection with a small projection area is placed at a location where the protrusion on the back of the body has a relatively small amount of protrusion, cushioning in line with the shape of the human body can be obtained by becoming deeper than the sink according to the amount of protrusion. It will be damaged.
In addition, when the back surface of the body is in a lying state, the area where the load on the bedding is large will sink because the protrusion on the elastic body has a relatively large area when the protrusion on the back surface of the body is small. Because it is shallow , cushioning that matches the shape of the human body can be obtained . In areas where the back surface of the body is heavily loaded on the bedding, the surface of the elastic body has a surface where the subsidence becomes deeper as the protrusion of the concavo-convex shape on the back of the body increases. If the protrusions are arranged so that the area of the protrusions decreases, a cushioning property in accordance with the shape of the human body can be obtained. In addition, if a part with a small projection area is placed at a location where the back surface of the body in the lying state exerts a large load on the bedding, the cushioning property conforms to the shape of the human body by becoming deeper than the sinking according to the load. It will be damaged.
When the back of the body is in a lying state, the load on the bedding is small. When the protrusion on the back of the body is large , the surface of the elastic body has a relatively small protrusion, so it sinks deeply. Therefore, cushioning properties that match the shape of the human body can be obtained. In areas where the back surface of the body is in a state where the load on the bedding is small, the surface of the elastic body has a surface where the subsidence becomes shallower as the projections of the uneven shape on the back surface of the body become smaller. If the protrusions are arranged so that the area of the protrusions increases, a cushioning property corresponding to the shape of the human body can be obtained. In addition, if a large projection is placed in a place where the back of the body in a lying state exerts a small load on the bedding, the cushioning property conforms to the shape of the human body by becoming shallower than the sinking according to the load. It will be damaged.
Further, the bedding having the above configuration is configured such that a plurality of bag portions extending in the width direction of the bedding are formed on the back side of the bedding, and a raising plate for partially raising the volume of the bedding can be stored in the bag portion. May be.
If comprised in this way, in addition to the effect | action by the bedding of the said structure, it will become possible to adjust the height of bedding partially.

The manufacturing method of a bedding according to the present invention is a bedding that includes an elastic body with protrusions having large, medium, and small areas on the surface, and the protrusion on the surface of the elastic body is an uneven protrusion on the back of the body. Whether the area of the protrusion does not change with respect to the change in the amount, or conversely changes, and the area of the protrusion does not change with respect to the change in the load exerted on the bedding by the back surface of the body lying down Or it arrange | positions and manufactures so that it may correspond, It is characterized by the above-mentioned.
In addition to the manufacturing method described above, the method for manufacturing a bedding according to the present invention measures the load distribution exerted on the bedding by the uneven shape of the back of the body and / or the back of the body in a lying state. An elastic body is manufactured on the basis of this, and the bedding is manufactured by interiorizing the manufactured elastic body.

Since the bedding according to the present invention is configured as described above, the bedding can have a cushioning property in accordance with the shape of the human body. Since protrusions having a relatively small area are arranged on the surface, the protrusion can sink deep according to the amount of protrusion, so that there is an effect of dispersing body pressure and 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.

  Furthermore, the bedding according to the present invention is configured such that a plurality of bag portions extending in the lateral direction of the bedding or the bedding cover are formed on the back side of the bedding, and a raising plate for partially raising the volume of the bedding can be accommodated in the bag portion. If it comprises, it becomes possible to adjust the height of bedding. 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.

  In addition, the method for manufacturing a bedding according to the present invention includes an elastic body 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 on the back of the body in a lying state on the bedding. If the bedding is manufactured by interior decoration, it is possible to manufacture a bedding excellent in durability and pressure dispersibility according to differences in physique due to gender differences and differences in physique due to individual differences.

  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.

The bedding manufactured in this way can provide a bedding having excellent durability and pressure dispersibility according to differences in physique due to gender differences and differences in physique due to individual differences.

  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. In FIG. 2, B is a urethane foam for measurement having a predetermined width with a protrusion having a medium area on the surface. 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, and the upper face is Three rows of mushroom-like projections B2 having a rectangular shape and an area of about 40 mm × 60 mm are formed. In FIG. 3, 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 approximately Three rows of mushroom-like projections C2 of 30 mm × 60 mm are formed. 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 area of the protrusion does not change or reverse with respect to the change in the protrusion amount of the uneven shape on the back of the body, and the body is lying The area of the protrusion is not changed or coincides with the change in the load exerted on the bedding by the back surface of the bedding.

  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 in which the measurement urethane foams A, B, and C 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 front end side of the head 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. The 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 bedding of the portion corresponding to the leg portion 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.
