Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. The vertical, horizontal, and front-back directions in the following description are as shown in FIG. 1 and the like. The vertical direction here is merely defined for convenience so as to match the thickness direction of the bedding.

<First Embodiment>
<< Overall composition of bedding >>
FIG. 1 is a schematic side sectional view of the bedding 101 according to the first embodiment. The bedding 101 supports the user P who takes a sleeping posture from below. As shown in FIG. 1, the height direction of the user P coincides with the front-back direction.

The bedding 101 includes a first cushion set 41 to a third cushion set 43, a pad 5, and an overall cover 6.

The first cushion set 41 includes a first upper cushion body (topper core) 11, a first lower cushion body (base core) 21, and a first inner cover (cushion body cover) 31.

The first upper cushion body 11 has a first repulsive layer 11A and a second repulsive layer 11B, and has a rectangular parallelepiped shape with the vertical direction as the thickness direction. The repulsive force of the first repulsive layer 11A and the repulsive force of the second repulsive layer 11B are different. In the example of FIG. 1, the first repulsive layer 11A is arranged above the second repulsive layer 11B. That is, in the first upper cushion body 11, layers having different repulsive forces are vertically laminated.

The first repulsive layer 11A and the second repulsive layer 11B are formed by a filament three-dimensional bond obtained by three-dimensionally fusion-bonding filaments made of a thermoplastic resin. Since the method for producing the filament three-dimensional conjugate is known, for example, as disclosed in Japanese Patent Application Laid-Open No. 2020-26586, detailed description thereof will be omitted.

Regarding the formation of the first upper cushion body 11, for example, the first repulsive layer 11A and the second repulsive layer 11B are formed as separate bodies, and the first upper cushion body 11 is formed by adhering them together by adhesion or the like. be able to. However, the first upper cushion body 11 may be formed as an integral body in which the first repulsive layer 11A and the second repulsive layer 11B are integrated from the beginning. Such a cushion body can be realized, for example, by making the filament relatively thicker or increasing the bulk density of the filament with respect to the one having the higher repulsive force at the time of manufacturing the integral body (filament three-dimensional bond). Is.

The first upper cushion body 11 is arranged above the first lower cushion body 21. The first lower cushion body 21 has a rectangular parallelepiped shape with the vertical direction as the thickness direction, and is formed by a filament three-dimensional coupling as in the case of the first upper cushion body 11.

The first cushion set is formed by covering the set formed by placing the first upper cushion body 11 above the first lower cushion body 21 (set S in FIG. 3 described later) with the first inner cover 31. 41 is formed.

The second cushion set 42 has a second upper cushion body 12, a second lower cushion body 22, and a second inner cover 32. Since the basic configuration of the second cushion set 42 is the same as the configuration of the first cushion set 41 described above, the description will be simplified. The second upper cushion body 12 is formed by vertically laminating a first repulsive layer 12A and a second repulsive layer 12B having different repulsive forces.

The third cushion set 43 has a third upper cushion body 13, a third lower cushion body 23, and a third inner cover 33. Since the basic configuration of the third cushion set 43 is the same as the configuration of the first cushion set 41 described above, the description will be simplified. The third upper cushion body 13 is formed by vertically laminating a first repulsive layer 13A and a second repulsive layer 13B having different repulsive forces.

The first cushion set 41, the second cushion set 42, and the third cushion set 43 are arranged in this order from the front to the rear. That is, the plurality of cushion sets 41 to 43, and thus the plurality of upper cushion bodies 11 to 13, are arranged side by side in the height direction of the user P.

The pad 5 is one member arranged above the first cushion set 41, the second cushion set 42, and the third cushion set 43. The pad 5 has a rectangular parallelepiped shape with the vertical direction as the thickness direction. The pad 5 has almost no repulsive force and is sufficiently soft as compared with each cushion body used for the bedding 101. The pad 5 is made of, for example, a polyester material.

The bedding 101 is formed by covering the first cushion set 41, the second cushion set 42, the third cushion set 43, and the pad 5 with the entire cover 6. The user P takes a sleeping posture by placing his / her back side on the top surface portion 61 (also shown in FIG. 5 described later) of the overall cover 6, and is supported by receiving a repulsive force from the bedding 101.

When the user P is in the sleeping posture as described above, as shown in FIG. 1, the head and back of the user P are supported by the first cushion set 41, and the buttocks of the user P are the second cushion set. It is supported by 42, and the leg of the user P is supported by the third cushion set 43. The distribution of the parts of the user P supported by each of such cushion sets is not limited to the above. Further, the number of cushion sets is not limited to three as shown in FIG. 1, and may be a plurality of cushion sets other than three, or may be one.

<< Repulsive force of cushion body >>
The "repulsive force" of the cushion body in the present application will be described. The sample is cut parallel to the thickness direction to prepare a rectangular parallelepiped specimen having a square upper surface (top surface) having a side of 300 mm. Next, a loader having a disk-shaped pressure plate having a diameter of 150 mm attached to the tip portion is placed on the upper surface of the specimen. Then, the loader is lowered at a speed of 0.4167 mm / s to compress the sample in the thickness direction, and the load is applied when the compressed thickness (mm) of the specimen becomes 7.5 mm smaller than the initial thickness. Record the value L1 (N) of the load applied to the child. Let this load value L1 be the compressive repulsive force (N). The "repulsive force" in the present application corresponds to the compressive repulsive force that can be grasped in this way.
Specifically, the repulsive force of each of the upper cushion bodies 11 to 13 and each of the lower cushion bodies 21 to 23 is set as follows, for example. The thickness of the upper cushion body is, for example, 50 mm, and the thickness of the lower cushion body is, for example, 150 mm.

In the first upper cushion body 11, the repulsive force of the first repulsive layer 11A is usually preferably in the range of 80 to 120 N, and in the example of the present embodiment, it is 100 N. The repulsive force of the second repulsive layer 11B is usually preferably in the range of 50 to 90N, and is 70N in the example of the present embodiment. In the second upper cushion body 12, the repulsive force of the first repulsive layer 12A is usually preferably in the range of 120 to 160N, and in the example of the present embodiment, it is 140N. The repulsive force of the second repulsive layer 12B is usually preferably in the range of 90 to 130 N, and in the example of the present embodiment, it is 110 N. In the third upper cushion body 13, the repulsive force of the first repulsive layer 13A is usually preferably in the range of 100 to 140 N, and in the example of the present embodiment, it is 120 N. The repulsive force of the second repulsive layer 13B is usually preferably in the range of 70 to 110 N, and in the example of the present embodiment, it is 90 N.

The repulsive force of each of the lower cushion bodies 21 to 23 is usually preferably in the range of 60 to 100 N, and is 80 N in the example of the present embodiment. The lower cushion bodies 21 to 23 have a lower density than the upper cushion bodies 21 to 23, and are formed of filaments having a relatively thin wire diameter, and the repulsive forces of the lower cushion bodies 21 to 23 correspond to each other. It is lower than the repulsive force of the upper cushion bodies 11 to 13. For example, the wire diameter of the filaments of the upper cushion bodies 21 to 23 is about 0.85 mm, while the wire diameter of the filaments of the lower cushion bodies 21 to 23 is about 0.6 mm.

The repulsive force (80N) of the first lower cushion body 21 is set lower than the higher repulsive force (100N) of the two layers of the first upper cushion body 11, and the first upper cushion body 11 It is set lower than the overall repulsive force of 11. However, the repulsive force of the first lower cushion body 21 may be set lower than the repulsive force of any of the two layers in the first upper cushion body 11. In each cushion body (elastic body), the higher the repulsive force, the harder the user feels, and the lower the repulsive force, the softer the user feels.

The first upper cushion body 11 can be placed above the first lower cushion body 21 with the upper and lower sides switched. That is, it is possible to select a state in which the first repulsion layer 11A is above the second repulsion layer 11B and a state in which the second repulsion layer 11B is above the first repulsion layer 11A. In other words, the first upper cushion body 11 can be turned upside down.

Similarly, the second upper cushion body 12 and the third upper cushion body 13 are respectively placed above the second lower cushion body 22 and the third lower cushion body 23 so as to be interchangeably upper and lower.

FIG. 2 shows a state in which the upper and lower sides of the upper cushion bodies 11 to 13 are interchanged from the state of FIG. Therefore, in the state of FIG. 2, in each of the upper cushion bodies 11 to 13, the second repulsive layers 11B to 13B are arranged above the first repulsive layers 11A to 13A.

Since the upper cushion bodies 11 to 13 can be interchanged up and down in this way, the repulsive force against the user P in the sleeping posture can be adjusted, and the sleeping comfort can be easily adjusted to suit the user P. In particular, as compared with the case where one cushion body having the same thickness as the thickness (vertical length) of the set consisting of the upper cushion body and the lower cushion body of the present embodiment is formed into a two-layer structure and the upper and lower parts are interchanged. Since the upper and lower cushion bodies having a thin thickness may be exchanged above the lower cushion body, the burden of repulsive force adjustment work can be reduced.

Further, since the plurality of upper cushion bodies 11 to 13 are arranged side by side in the height direction of the user P, the repulsive force can be adjusted for each part of the supporting user P. Therefore, the bedding 101 can be adjusted to the user's favorite sleeping comfort.

Further, sets including lower cushion bodies 21 to 23 and upper cushion bodies 11 to 13 corresponding to the upper and lower sides are arranged side by side in the height direction of the user P. As a result, the lower cushion body can be subdivided as compared with the case where the lower cushion body is formed as one cushion body below the upper cushion bodies 11 to 13, so that the lower cushion body can be easily carried. Further, each repulsive force of the lower cushion bodies 21 to 23 can be adjusted individually.

<< Accommodation by inner cover >>
Next, the configuration in which the cushion body is accommodated by the inner covers 31 to 33 will be described in detail. Since the accommodation configuration by the inner covers 31 to 33 is common, the accommodation configuration by the first inner cover 31 will be typically described here for convenience. Further, in the following description, the ordinal number "first" attached to the name of the member will be omitted.

FIG. 3 is a schematic perspective view showing a set S formed of the inner cover 31, the upper cushion body 11 and the lower cushion body 21 and accommodated by the inner cover 31. The set S is formed in the shape of a rectangular parallelepiped plate whose thickness direction is the vertical direction. Since the vertical direction is the thickness direction, the upper surface and the lower surface of the set S are sufficiently wider than the front, rear, left, and right side surfaces.

The inner cover 31 is formed of a smooth sheet material made of, for example, resin or various fibers, and has an upper surface portion 311 corresponding to the upper surface and a lower surface portion 312 corresponding to the lower surface according to the shape of the set S. , And side surface portions 313 corresponding to the front, rear, left and right side surfaces. The front, rear, left, and right outer edges of the upper surface portion 311 and the lower surface portion 312 are connected to the outer edges of the front, rear, left, and right side surface portions 313. That is, the inner cover 31 has a side surface portion 313 that covers the side surface of the entire circumference of the set S, and the upper surface portion 311 and the lower surface portion 312 are connected to the side surface portion 313.

More specifically, the outer edges of the upper surface portion 311 and the lower surface portion 312 of the inner cover 31 are formed to have substantially the same shape and dimensions as the outer edges of the upper and lower surfaces of the set S. Further, the outer edges of the left and right side surface portions 313 of the inner cover 31 are formed to have substantially the same shape and dimensions as the outer edges of the left and right surface portions of the set S, and the outer edges of the front and rear side surface portions 313 of the inner cover 31 are formed of the set S. It is formed to have almost the same shape and dimensions as the outer edges of the front and rear surfaces.

Therefore, the set S housed in the inner cover 31 is adapted to fit the inner surface of the inner cover 31. Further, in this state, the upper surface portion 311 faces the upper surface of the set S, and the lower surface portion 312 faces the lower surface of the set S.

Further, an upper opening 311A is formed on the upper surface 311 of the inner cover 31, and a lower opening 312A is formed on the lower surface 312 of the inner cover 31. The upper opening 311A is provided so as to open a region near the center of the upper surface portion 311 and exposes a region near the center on the upper surface of the housed set S. The lower opening 312A is provided so as to open a region closer to the center of the lower surface portion 312, and exposes a region closer to the center on the lower surface of the housed set S.

In the example of the present embodiment, the shapes and sizes of the upper and lower openings 311A and 312A are the same, and the outer edge shape of each opening 311A and 312A is substantially similar to the outer edge shape of the upper surface portion 311 or the lower surface portion 312. be. Further, in the example of the present embodiment, the area of the upper and lower openings 311A and 312A is set to about 60 to 80% of the area of the upper surface portion 311 or the lower surface portion 312, and the respective openings 311A and 312A are the upper surfaces. It is arranged so that the center positions coincide with the portion 311 or the lower surface portion 312.

Therefore, in the state where the set S is housed in the inner cover 31, the upper surface portion 311 covers only the vicinity of the entire outer edge of the upper surface of the set S, and the lower surface portion 312 covers only the vicinity of the entire outer edge of the lower surface of the set S. Become. Further, since the upper surface portion 311 and the lower surface portion 312 have large openings in this way, as shown by the arrows in FIG. 1, the set S can be accommodated inside the inner cover 31 by using the openings. Is.

When the set S is housed in this way, it can be easily housed by bending the set S lightly or extending the set S lightly. Further, in the present embodiment, the set S can be detachably accommodated in both the upper surface portion 311 and the lower surface portion 312 through the opening, but only one of the upper surface portion 311 and the lower surface portion 312 is described as such. It may be possible to accommodate various animals.

A cushion set can be formed by accommodating the set S inside the inner cover 31. FIG. 4 is a schematic perspective view of the cushion set 41.

As shown in FIG. 4, in the cushion set 41, most of the upper surface and the lower surface of the set S near the center are exposed, and the air permeability of the set S is not impaired in this exposed area. As described above, even if the set S is housed in the inner cover 31, the excellent air permeability of the set S, which is a three-dimensional filament conjugate, is hardly impaired, and the cushion set 41 maintains the excellent air permeability.

On the other hand, in the cushion set 41, the inner cover 31 covers the entire front, rear, left and right side surfaces of the set S, and the vicinity of the entire outer edge of the upper surface and the lower surface, and the set S unintentionally covers the inner cover 31. Deviation to is suppressed as much as possible. Further, since the inner cover 31 covers the entire front, rear, left and right side surfaces of the set S, it is possible to suppress the deviation between the upper cushion body 11 and the lower cushion body 21 in the set S. Further, the surface of the cushion set 41 is in a smooth state at least in the portion covered by the inner cover 31.

<< Bedding assembly process >>
Such cushion sets 41 to 43 are suitable as cushion members for forming the bedding 101. Here, as shown in FIG. 5, a plurality of cushion sets 41 to 43 are prepared, and by accommodating these in one bag-shaped overall cover 6, the bedding 101 is formed.

More specifically, the entire cover 6 has a rectangular parallelepiped shape with the vertical direction as the thickness direction, and has a top surface portion 61 and a box-shaped portion 62. That is, the box-shaped portion 62 is composed of the six faces of the rectangular parallelepiped shape excluding the top surface (upper surface). The top surface portion 61 is arranged so as to cover the opening 62A opened above the box-shaped portion 62. That is, the top surface portion 61 functions as a lid of the box-shaped portion 62. The top surface portion 61 and the box-shaped portion 62 are connected by a zipper (fastener) 63 provided on the upper surface outer edge portion of the box-shaped portion 62 and the outer edge portion of the top surface portion 61.

In the example of FIG. 5, the zipper 63 connects the entire four sides of the upper surface of the box-shaped portion 62 to the entire four sides of the top surface portion 61. Therefore, by opening the zipper 63, the top surface portion 61 can be separated from the box-shaped portion 62. On the contrary, when closing the zipper 63, the handle of the zipper 63 is moved over all four sides of the upper surface of the box-shaped portion 62 to fix the top surface portion 61 to the box-shaped portion 62.

Not limited to the above, the zipper 63 is provided only on three of the four sides of the upper surface of the box-shaped portion 62, and even if the remaining one side and one side of the corresponding top surface portion 61 are inseparably connected. good. In this case, the zipper 63 is formed in a U shape when viewed upward.

When assembling the bedding 101, the steps of the following procedure are carried out. First, the plurality of cushion sets 41 to 43 assembled as described above are housed side by side in the front-rear direction inside the box-shaped portion 62 through the opening 62A. After completing the accommodating step of accommodating all the cushion sets 41 to 43, the pad 5 is placed on the upper side of the cushion sets 41 to 43. After that, the bedding 101 is completed by closing the zipper 63 and covering the opening 62A with the top surface portion 61.

Here, in the above-mentioned accommodating step, when each set S is directly accommodated in the entire cover 6 without providing the inner covers 31 to 33, the non-smooth surface portion (of the surface, for example, the tip of the filament is formed) in the set S. The protruding portion) may be caught by the entire cover 6 and hinder the smooth progress of the accommodating process. In particular, when the box-shaped portion 62 is accommodated through the opening 62A as described above, the side surface portion of the set S is particularly likely to be caught by the entire cover 6.

However, in the cushion sets 41 to 43 according to the present embodiment, since the set S is housed in the inner covers 31 to 33 having a smooth surface, the above-mentioned catching is suppressed at least in the portion covered by the inner covers 31 to 33. Will be done. The cushion sets 41 to 43 are exposed in the central region of the upper surface and the lower surface of the set S from the viewpoint of not impairing the air permeability, but the entire side surface of the set S is covered by the inner covers 31 to 33. Therefore, the effect of suppressing the above-mentioned catching is high.

Further, since the zipper 63 is provided on the outer edge of the upper surface of the box-shaped portion 62, the opening 62A is opened by opening the zipper 63, and the cushion sets 41 to 43 can be easily taken out upward. As a result, it becomes easy to readjust the repulsive force by exchanging the upper and lower sides of the upper cushion bodies 11 to 13 in the cushion sets 41 to 43. This makes it possible to streamline the operation of the bedding 101, for example, in a hotel or the like.

<Second Embodiment>
FIG. 6 is a schematic side sectional view of the bedding 102 according to the second embodiment. In FIG. 6, the front and rear cushion bodies are displayed separately from each other in consideration of easy viewing, but in reality, they are arranged in close contact with each other. Here, the differences from the first embodiment will be mainly described.

The bedding 102 has each upper cushion body 11 to 13, each lower cushion body 21 to 23, and a pad (first pad) 5 as in the first embodiment. The bedding 102 has a second pad 7 which is different from the first embodiment.

The second pad 7 is configured in the same manner as the first pad 5 described above. The second pad 7 is one member arranged so as to be sandwiched in the vertical direction by the upper cushion bodies 11 to 13 and the lower cushion bodies 21 to 23. Although the inner cover is provided in the first embodiment, this is omitted in the present embodiment. It should be noted that each of the upper cushion bodies 11 to 13 and each of the lower cushion bodies 21 to 23 is provided with a frame-shaped inner cover (an inner cover having an opening in a region closer to the center on both or one of the upper surface portion and the lower surface portion). ) May be accommodated individually.

In the present embodiment, by providing the second pad 7, it is possible to further increase the softness (so-called fluffy feeling) felt by the user. It is also possible to stack the first pad 5 and the second pad 7 on top of each of the upper cushion bodies 11 to 13, but the appropriate repulsive force felt by the user is reduced and it is easy to turn over. May be impaired. In this respect, by arranging the second pad 7 between the upper cushion body and the lower cushion body as in the present embodiment, it is possible to suppress the difficulty of turning over from being impaired as much as possible. Further, by arranging the second pad 7 in this way, the user can easily feel the change in hardness, and the effect of making it difficult to get stuffy can be expected.

<Others>
As described above, the bedding of each embodiment is a bedding that has a lower cushion body and an upper cushion body arranged above the lower cushion body, and supports the user from below. The repulsive force of the side cushion body is made smaller than the repulsive force of the upper cushion body. Therefore, compared to the case where the repulsive force of the lower cushion body is made larger than the repulsive force of the upper cushion body, the deformation of the bedding due to a change in the load when the user turns over, for example, is lower (user). It can be generated (on the side far from the side) to make the user feel that it is gradually deformed, and it is possible to easily give the user a comfortable sleep.

In addition, the upper cushion body is formed thinner (smaller in the vertical direction) than the lower cushion body, and layers having different repulsive forces are laminated on the upper and lower sides so that the upper and lower cushion bodies can be interchanged. ing. By thinning the upper cushion body, the returnability from sinking to returning like a spring is improved, and bedding that is easier to turn over is realized.

Although the embodiments of the present invention have been described above, the configuration of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the invention. That is, the above embodiment should be considered to be exemplary in all respects and not restrictive. The technical scope of the present invention is shown not by the description of the above embodiment but by the scope of claims, and is understood to include all modifications belonging to the meaning and scope equivalent to the scope of claims.
