Summary of the Invention

Problems to be Solved by the Invention

[0004] In a hanging bedding, the internal space of the side fabric may be partitioned by a partition part such as a selvage fabric. When the partition part is located on the body of the user of the hanging bedding, there is a possibility that the user may lift the hanging bedding when turning over. When the user lifts the hanging bedding, cold air may enter between the user and the hanging bedding. There is room for improvement in maintaining the heat retention property of the hanging bedding.

[0005] An object of the present disclosure is to provide a hanging bedding capable of maintaining heat retention and a method for manufacturing the hanging bedding.

Means for Solving the Problems

[0006] The bedding relating to this disclosure is (1) a bedding that covers the user's body. The bedding comprises a first outer fabric, a second outer fabric that is superimposed on the first outer fabric and sewn to the first outer fabric, and a plurality of partitions that divide the internal space defined by the first and second outer fabrics. The first and second outer fabrics include a first portion that covers the user's upper body and a second portion that is aligned with the first portion along a first direction. The plurality of partitions include a pair of inclined partitions that are inclined in the first portion with respect to a second direction perpendicular to the first direction and aligned along the second direction. The pair of inclined partitions extend toward a virtual reference line that passes through the center of the first and second outer fabrics and extends toward the second direction, so as to move toward each other. Between the pair of inclined partitions the bedding has a shoulder covering portion that accommodates the user's shoulders.

[0007] This bedding comprises a first cover, a second cover, and a plurality of dividers. The plurality of dividers include a pair of inclined dividers. The pair of inclined dividers are inclined with respect to a second direction. The pair of inclined dividers extend so as to move away from each other toward a virtual reference line. The bedding has shoulder coverings between the pair of inclined dividers that accommodate the user's shoulders. Because the pair of inclined dividers are inclined so as to move away from each other toward a virtual reference line, the dividers can conform to the shape of the user's body, making it less likely for the bedding to separate from the user's body. Because the shoulder coverings that accommodate the user's shoulders are positioned between the pair of inclined dividers, the inclined dividers can be prevented from being positioned over the user's body, reducing the possibility of the bedding being lifted when the user turns over in their sleep. Therefore, the gap formed between the user's body and the bedding can be reduced, and the heat retention of the bedding can be maintained.

[0008] (2) In (1) above, each of the pair of inclined partitions may be inclined at an angle of 20° or more and 60° or less with respect to the second direction. By inclining the inclined partition at an angle of 20° or more with respect to the second direction, the shape of the inclined partition in plan view can be made to conform to the user's body, thereby improving the fit. By inclining the inclined partition at an angle of 60° or less with respect to the second direction, the amount of cold air entering the bedding from between the pair of inclined partitions can be reduced.

[0009] (3) In (1) or (2) above, the multiple partitions may include auxiliary partitions that extend from at least one of the pair of inclined partitions to the edges of the first and second fabrics. When the bedding covers the user's body, the bedding curves in the thickness direction of the first and second fabrics, and the ends of the first and second fabrics along the first direction may be oblique to the first direction. At this time, the auxiliary partitions act as guides to stretch the inclined partitions in the width direction of the user's body. In this way, the auxiliary partitions can function as guides.

[0010] (4) In any of (1) to (3) above, each of the multiple partitions may include a gusset. The width of the gusset located in the center in the second direction may be greater than the width of the gusset located at the end in the second direction. A larger width for the gusset located in the center in the second direction makes it easier to make the center of the bedding bulge. This makes it possible to maintain warmth for the user covered by the bedding more reliably. A smaller width for the gusset located at the end in the second direction makes it possible to lower the center of gravity of the end of the bedding. This makes it possible to reduce the gap formed between the bedding and the user.

[0011] (5) In any of (1) to (4) above, a portion of the multiple partitions may extend in a second direction. The distance between the edge extending in the second direction in the second portion and the adjacent partition along the first direction may be narrower than the distance between a pair of partitions that sandwich the imaginary reference line in the first direction. In this case, the comforter can be made less likely to move between the edge of the comforter and the adjacent partition. Therefore, the gap formed between the comforter and the user at the edge of the comforter can be reduced.

[0012] (6) In any of (1) to (5) above, the length of the first outer fabric in the first direction may be longer than the length of the second outer fabric in the first direction. The length of the first outer fabric in the second direction may be longer than the length of the second outer fabric in the second direction. The first outer fabric may have multiple tucks. By providing tucks, a specific part of the bedding can be made to bulge. This makes it less likely for the bedding to separate from the user's body.

[0013] (7) In (6) above, some of the multiple tucks may be provided on the edge of the first fabric. By providing the tucks on the edge of the first fabric, the tucks can be made less noticeable.

[0014] (8) In (6) above, some of the tucks may be provided at locations other than the edge of the first fabric. In this case, the tucks can create an uneven surface on the fabric of the bedding that faces the user's body. This uneven surface can further reduce the gap formed between the bedding and the user.

[0015] (9) In (6) or (7) above, some of the tucks may be provided on the outside of the shoulder covering portion. This makes it possible to widen the area between the pair of inclined partition portions.

[0016] (10) In any of (1) to (9) above, the bedding may include a pair of shoulder coverings. The pair of shoulder coverings may be arranged along the second direction. In this case, even if two users sleep side by side along the second direction, the shoulder coverings will be positioned on each user's shoulders, preventing cold air from entering through the gap formed between the users' bodies and the bedding.

[0017] The method for manufacturing a bedding garment according to this disclosure is (11) a method for manufacturing a bedding garment that covers the body of a user. The method for manufacturing a bedding garment comprises the steps of sewing a plurality of gusset fabrics that will form a partition to a first outer fabric, overlapping a second outer fabric with the first outer fabric and the plurality of gusset fabrics, and sewing the plurality of gusset fabrics and the first outer fabric to the second outer fabric. The first and second outer fabrics include a first portion that covers the upper body of the user and a second portion that is aligned with the first portion along a first direction. The plurality of gusset fabrics include a pair of inclined gusset fabrics that are inclined in the first portion with respect to a second direction perpendicular to the first direction and aligned along the second direction. The pair of inclined gusset fabrics extend toward a virtual reference line that passes through the center of the first and second outer fabrics and extends toward the second direction, so as to move toward each other. Between the pair of inclined gusset fabrics is a shoulder covering portion that accommodates the shoulders of the user. The method for manufacturing a bedding garment according to this disclosure is used to manufacture the bedding garment described above. Therefore, the same effects as those of the aforementioned bedding can be obtained from this method of manufacturing bedding. [Effects of the Invention]

Mode for Carrying Out the Invention

[0020] Hereinafter, embodiments of the covering bedding according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant descriptions are omitted as appropriate. The drawings may be drawn with some parts simplified or exaggerated for ease of understanding, and dimensional ratios and the like are not limited to those shown in the drawings.

[0021] (First Embodiment) Figure 1 is a plan view showing the bedding 1 according to the first embodiment. Figure 2(a) is a cross-sectional view along the line II-II shown in Figure 1. Figure 2(b) is an enlarged view showing the gusset fabric 6 in the tuck T described later. The bedding 1 covers the body of the user H (see Figure 3). The bedding 1 is bedding that is at least partly made of a heat-retaining material. The bedding 1 has a heat-retaining function that keeps the user H warm. "User" is the person who uses the bedding 1. User H is, for example, the person who puts the bedding 1 over their own body. The bedding 1 is, for example, a down comforter, a synthetic fiber comforter, a lightweight comforter, or a blanket.

[0022] The bedding 1 comprises a front fabric 2 (second fabric), a back fabric 3 (first fabric), and a number of partitions 4. In the following description, the longitudinal direction of the bedding 1 will be referred to as the first direction D1, the width direction of the bedding 1 as the second direction D2, and the direction perpendicular to both the first direction D1 and the second direction D2 as the third direction D3. However, these directions are for the convenience of explanation and do not limit the position or direction of the object. The first direction D1 is the direction in which the body of the user H covered by the bedding 1 extends. The second direction D2 is the direction that intersects the first direction D1. As an example, the first direction D1 and the second direction D2 are perpendicular to each other. The third direction D3 is the thickness direction of the bedding 1.

[0023] The outer fabric 2 extends in a first direction D1. "Outer fabric" refers to the outer fabric of the bedding that is exposed to the outside when the bedding is covering the user. The outer fabric 2 is oriented, for example, away from the user H. The outer fabric 2 is, for example, rectangular in shape. In this disclosure, "rectangular" includes not only a strictly rectangular shape, but also shapes that are not strictly rectangular but appear rectangular, such as a rounded-corner rectangle or a rectangle with cut-off corners. "Rectangular" includes a square in which the lengths of the four sides are equal. The length of the outer fabric 2 in the first direction D1 is longer than the length of the outer fabric 2 in the second direction D2. The length of the outer fabric 2 in the first direction D1 may be shorter than the length of the outer fabric 2 in the second direction D2. The length of the outer fabric 2 in the first direction D1 is, for example, 150 cm or more and 250 cm or less. The length of the outer fabric 2 in the second direction D2 is, for example, 100 cm or more and 230 cm or less.

[0024] The backing fabric 3 extends in the first direction D1. "Backing fabric" refers to the outer fabric of the bedding that is in contact with the user without being exposed to the outside when the bedding covers the user. The backing fabric 3 is oriented opposite to the fronting fabric 2. The backing fabric 3 is in contact with the user H, for example. The backing fabric 3 is, for example, rectangular in shape. The length of the backing fabric 3 in the first direction D1 is longer than the length of the backing fabric 3 in the second direction D2. The length of the backing fabric 3 in the first direction D1 may be shorter than the length of the backing fabric 3 in the second direction D2. The length of the backing fabric 3 in the first direction D1 is, for example, 200 cm or more and 270 cm or less. The length of the backing fabric 3 in the second direction D2 is, for example, 100 cm or more and 250 cm or less.

[0025] When the lining fabric 3 is not sewn to the outer fabric 2, the area of ​​the lining fabric 3 is larger than the area of ​​the outer fabric 2. In this case, the length of the lining fabric 3 in the first direction D1 is longer than the length of the outer fabric 2 in the first direction D1, and the length of the lining fabric 3 in the second direction D2 is longer than the length of the outer fabric 2 in the second direction D2. The difference between the length of the outer fabric 2 in the first direction D1 and the length of the lining fabric 3 in the first direction D1 is, for example, 1 cm or more and 20 cm or less. The difference between the length of the outer fabric 2 in the second direction D2 and the length of the lining fabric 3 in the second direction D2 is, for example, 1 cm or more and 20 cm or less. The outer fabric 2 is layered on top of the lining fabric 3. The lining fabric 3 is sewn to the outer fabric 2. The edge 3a of the lining fabric 3 is sewn to the edge 2a of the outer fabric 2.

[0026] "Edge of the outer fabric" and "edge of the inner fabric" refer to the periphery of the outer fabric and inner fabric, respectively. In the following description, the edges of the outer fabric 2 and inner fabric 3 sewn together along the second direction D2 may be described as the first side 1a and the second side 1b of the bedding 1. The edges of the outer fabric 2 and inner fabric 3 sewn together along the first direction D1 may be described as the third side 1c and the fourth side 1d of the bedding 1. The first side 1a is included in the first part A described later. The second side 1b is included in the second part B described later. The third side 1c is located on one side of the second direction D2 of the bedding 1. The fourth side 1d is located on the other side of the second direction D2 of the bedding 1.

[0027] The outer fabric 2 and inner fabric 3 are made of, for example, a heat-retaining material. A "heat-retaining material" is a material that insulates to prevent the body heat of the user H of the bedding 1 from escaping to the outside of the bedding 1. The materials of the outer fabric 2 and inner fabric 3 are, for example, broadcloth, satin, blanket, or napped fabric. The outer fabric 2 and inner fabric 3 may also be woven or knitted fabrics made of, for example, cotton, wool, silk, or animal hair. Animal hairs may be, for example, cashmere, mohair, alpaca, camel, or angora. The materials of the outer fabric 2 and inner fabric 3 may also be woven or knitted fabrics made of, for example, acrylic, nylon, or polyester. The outer fabric 2 and inner fabric 3 may also be made of, for example, microfiber containing polyester.

[0028] The front fabric 2 and the back fabric 3 comprise a first part A and a second part B. The first part A covers the upper body of user H. "Upper body of user" refers to the part of the body located closer to the head than the waist of user H. The second part B covers the lower body of user H. "Lower body of user" refers to the part of the body located closer to the feet than the waist of user H. The second part B is aligned with the first part A along the first direction D1.

[0029] Multiple partitions 4 divide the internal space S defined by the outer fabric 2 and the inner fabric 3. The internal space S is the space between the outer fabric 2 and the inner fabric 3. One internal space S is defined between the outer fabric 2 and the inner fabric 3. The cross-sectional shape of the internal space S along the second direction D2 and the third direction D3 is, for example, polygonal (triangular in one example). The inner fabric 3 covers the stuffing together with the outer fabric 2. The compartments partitioned by the multiple partitions 4 in the internal space S are filled with stuffing. The stuffing is, for example, natural materials such as feathers, down, wool, silk or linen, or synthetic fibers such as polyester fiberfill or granular fiberfill. The stuffing may be a blend of natural materials and synthetic fibers. The stuffing may be a blend containing natural materials, for example. In this case, the stuffing is a silk blend or a wool blend.

[0030] Multiple partitions 4 divide the internal space S in the outer fabric 2 and inner fabric 3 into a first direction D1 and a second direction D2. The partitions 4 may be, for example, stitches, or gusset fabrics 6 sewn to both the outer fabric 2 and the inner fabric 3. The partitions 4 form a quilt in the bedding 1. The configuration in which the partitions 4 are gusset fabrics 6 will be described in detail later.

[0031] Some of the multiple partition sections 4 extend in a first direction D1, and other parts of the multiple partition sections 4 extend in a second direction D2. The multiple partition sections 4 have a first partition section 4a and a second partition section 4b. The first partition section 4a extends in the first direction D1. The partition section 4 has multiple (three in this example) first partition sections 4a. The multiple first partition sections 4a are arranged along the second direction D2.

[0032] As an example, in the three first partition sections 4a, the distance between the central first partition section 4a and the first partition section 4a adjacent to it is longer than the distance between the adjacent first partition section 4a and the third side 1c or the fourth side 1d. This makes it difficult for the end of the bedding 1 filled with stuffing to move in the second direction D2.

[0033] The second partition section 4b extends in the second direction D2. The partition section 4 has multiple (four in one example) second partition sections 4b. The multiple second partition sections 4b are arranged in the first direction D1. The spacing t1 between the multiple second partition sections 4b is, for example, 40 cm or more and 50 cm or less. For example, the first partition section 4a and the second partition section 4b are orthogonal to each other.

[0034] Multiple compartments C are formed by the first partition 4a and the second partition 4b. Each of the multiple compartments C has a first compartment C1 and a second compartment C2. The first compartment C1 is located near the center of the second direction D2 of the bedding 1. The first compartment C1 is divided by two first partitions 4a aligned along the second direction D2 and two second partitions 4b aligned along the first direction D1.

[0035] The second section C2 is adjacent to the first section C1. The second section C2 is located closer to the third side 1c and the fourth side 1d of the bedding 1 than the first section C1. The second section C2 is located at both ends of the second direction D2 of the bedding 1. The second section C2 is partitioned by the first partition 4a, two second partitions 4b aligned along the first direction D1, and the third side 1c or the fourth side 1d.

[0036] The width of the first section C1 in the second direction D2 is longer than the width of the second section C2 in the second direction D2. When viewed along the third direction D3, the area of ​​the first section C1 is larger than the area of ​​the second section C2. For example, the weight of the filling in the first section C1 is heavier than the weight of the filling in the second section C2. The weight of the filling in the first section C1 is, for example, 50g or more and 60g or less. The weight of the filling in the second section C2 is, for example, 40g or more and 50g or less. Because the weight of the second section C2 is lighter than the weight of the first section C1, when the bedding 1 is placed on the bed, the second section C2 is less likely to hang down from the edge of the bed, etc., and is less likely to be pulled down by gravity, thereby suppressing the formation of a large gap between the bedding 1 and the neck of the user H.

[0037] As mentioned above, each of the multiple partitions 4 includes a gusset fabric 6. In this case, the first partition 4a is the first gusset fabric 6a, and the second partition 4b is the second gusset fabric 6b. The first gusset fabric 6a and the second gusset fabric 6b form a three-dimensional quilt on the bedding 1 that has width in the third direction D3.

[0038] Figure 2(a) shows the bedding 1 in cross-section along the second direction D2 and the third direction D3. The width m1 of the gusset fabric 6 located at the center 1e in the second direction D2 of the bedding 1 is greater than the width m2 of the gusset fabric 6 located at the end 1f in the second direction D2 of the bedding 1. The width m1 is, for example, 6 cm or more and 15 cm or less. The width m2 is, for example, 1 cm or more and 10 cm or less.

[0039] Because the width m1 is larger than the width m2, the filling placed in the center of the duvet 1 in the second direction D2 can move more easily, and air can be more easily incorporated into the internal space S. As a result, the heat retention of the duvet 1 can be maintained in the center of the duvet 1 where the user H's body, covered by the duvet 1, comes into contact, and the drape (flexibility) of the duvet 1 can be improved.

[0040] Because the width m2 is smaller than the width m1, the center of gravity of the end 1f of the bedding 1 is lowered, and the gap between the bedding 1 and the user H can be reduced. This prevents the warm air between the bedding 1 and the user H from flowing out of the bedding 1. In the state where the outer fabric 2 and the inner fabric 3 are sewn together, the area of ​​the outer fabric 2 may be larger than the area of ​​the inner fabric 3.

[0041] Figure 3 is an enlarged plan view showing the shoulder covering portion 7. The multiple partition portions 4 include a pair of inclined partition portions 5. The pair of inclined partition portions 5 are located in the first portion A. The pair of inclined partition portions 5 are aligned along the second direction D2. The pair of inclined partition portions 5 are inclined with respect to the second direction D2. The pair of inclined partition portions 5 extend away from each other as they move toward the virtual reference line N (see Figure 1). The virtual reference line N passes through the center of the front fabric 2 and the back fabric 3 and extends toward the second direction D2. The virtual reference line N is assumed to be straight.

[0042] The pair of inclined partitions 5 are inclined to conform to the shape of the user H's shoulders and arms. The distance between the pair of inclined partitions 5 increases as it approaches the virtual reference line N. In the bedding 1 covering user H, the distance between the pair of inclined partitions 5 at user H's neck is shorter than the distance between the pair of inclined partitions 5 at user H's chest. This reduces the possibility of cold air entering the user H's neck area.

[0043] The pair of inclined partition sections 5 are, for example, straight. The ends 5a of the pair of inclined partition sections 5 are connected to the first partition section 4a. The ends 5a of the inclined partition section 5 are the ends of the inclined partition section 5 that are located closer to the virtual reference line N. The ends 5b of the pair of inclined partition sections 5 are connected to the first side 1a of the bedding 1, for example.

[0044] Each of the pair of inclined partitions 5 is inclined at an angle of 20° or more and 60° or less with respect to the second direction D2. The angle θ between each of the pair of inclined partitions 5 and the first side 1a of the bedding 1 is, for example, 20° or more and 60° or less. The angle θ may also be, for example, 30° or more and 50° or less. The angle θ is, as an example, 45°. When the angle θ is 20° or more and 60° or less, the fit to the user's body can be improved, and the amount of cold air entering the bedding 1 from between the pair of inclined partitions 5 can be reduced.

[0045] Multiple partition sections 4 include a third partition section 4c. For example, the third partition section 4c is located in the first section A. The third partition section 4c connects the ends 5a of a pair of inclined partition sections 5. The third partition section 4c extends in the second direction D2. The third partition section 4c is adjacent to the first side 1a of the bedding 1 in the first direction D1. The third partition section 4c is, for example, straight. The length of the third partition section 4c is shorter than the length of the second partition section 4b.

[0046] The bedding 1 has a shoulder covering section 7 that accommodates the user H's shoulders. "User's shoulders" refers to the area from where the user's arms connect to the torso to the base of the neck. The shoulder covering section 7 is located between a pair of inclined partition sections 5. The space between the pair of inclined partition sections 5 accommodates the user H's shoulders. The distance between the pair of inclined partition sections 5 is set to be the length that accommodates the user H's shoulders. For example, the distance between the pair of inclined partition sections 5 is longer than the shoulder width of a typical adult's shoulders.

[0047] The shoulder covering portion 7 is, for example, the portion enclosed by a pair of inclined partition portions 5, a third partition portion 4c, and the first side 1a of the bedding 1. The shape of the shoulder covering portion 7 is, for example, trapezoidal. The length of the shoulder covering portion 7 in the second direction D2 increases toward the virtual reference line N. The shoulder covering portion 7 is partitioned, for example, by a first partition portion 4a extending in the first direction D1 within the shoulder covering portion 7.

[0048] The multiple compartments C include a third compartment C3 and a fourth compartment C4. The third compartment C3 is located in the shoulder covering portion 7. The third compartment C3 is demarcated by the first partition portion 4a, the third partition portion 4c, the inclined partition portion 5, and the first side 1a of the bedding 1. In the bedding 1, multiple (two in this example) third compartments C3 are arranged in the shoulder covering portion 7. The third compartments C3 are aligned in the second direction D2. The shoulder covering portion 7 may be the part where the user H's neck rests. For example, two third compartments C3 arranged in the shoulder covering portion 7 allow the bedding 1 to conform to the shape of the user H's body.

[0049] The fourth compartment C4 is adjacent to the third compartment C3 in the first direction D1. The fourth compartment C4 is partitioned by a pair of first partitions 4a, second partition 4b, and third partition 4c, which are aligned along the second direction D2. The weight of the filling to be placed in the third compartment C3 is lighter than the weight of the filling to be placed in the fourth compartment C4. The weight of the filling to be placed in the third compartment C3 is, for example, 10g or more and 30g or less. The weight of the filling to be placed in the fourth compartment C4 is, for example, 20g or more and 40g or less.

[0050] The weight of the filling in the third compartment C3 and the weight of the filling in the fourth compartment C4 are both lighter than the weight of the filling in the first compartment C1. For example, the weight of the filling in the shoulder covering 7 is lighter than the weight of the filling in other parts of the bedding 1. In this case, pressure on the user H's face can be suppressed.

[0051] Refer to Figure 1 again. The distance y1 between the vertex K of the bedding 1 and the end 5b of the inclined partition 5 is longer than the distance y2 between the end 5b and the intersection R. The intersection R is the intersection of the first partition 4a and the first side 1a. Distance y1 is, for example, 40 cm or more and 60 cm or less. Distance y2 is, for example, 20 cm or more and 30 cm or less. Because distance y2 is shorter than distance y1, it is possible to easily fit the user H's shoulders into the shoulder covering portion 7.

[0052] Multiple partition sections 4 include auxiliary partition sections 8. Each of the auxiliary partition sections 8 extends from at least one of the pair of inclined partition sections 5 to the edge 2a of the front fabric 2 and the edge 3a of the back fabric 3. Multiple partition sections 4 include a pair of auxiliary partition sections 8. Each of the pair of auxiliary partition sections 8 extends from each of the pair of inclined partition sections 5 to the edges 2a, 3a.

[0053] For example, one auxiliary partition 8 extends from the end 5a of the inclined partition 5 to the third side 1c of the bedding 1, and the other auxiliary partition 8 extends from the end 5a of the inclined partition 5 to the fourth side 1d of the bedding 1. The intersection point P of the auxiliary partition 8 and the third side 1c is located closer to the first side 1a than the straight line L passing through the ends 5a of the pair of inclined partitions 5. The same applies to the intersection point P of the auxiliary partition 8 and the fourth side 1d. The auxiliary partition 8 is inclined with respect to the straight line L, for example. The auxiliary partition 8 is inclined from the end 5a of the inclined partition 5 towards the first side 1a. The auxiliary partition 8 is, for example, straight.

[0054] Figures 4(a) and 4(b) are plan views illustrating the auxiliary partition 8. Figure 4(a) shows the bedding 1 without covering the user H's body. Figure 4(b) shows the bedding 1 with the user H's body covered. When the bedding 1 covers the user H's body, the bedding 1 curves in a third direction D3 (for example, upward), and the third side 1c and fourth side 1d of the bedding 1 may be inclined with respect to the first direction D1, as shown in Figure 4(b). At this time, the auxiliary partition 8 acts as a guide to stretch the inclined partition 5 in the width direction of the user H's body.

[0055] The auxiliary partition 8 functions as a guide to extend the inclined partition 5 in the width direction. The auxiliary partition 8 of the bedding 1 covering the user H's body allows the angle θ to be reduced, for example, compared to the bedding 1 not covering the user H's body. This makes it more difficult for the bedding 1 to separate from the user H's body.

[0056] Figure 5 is a side view showing the bedding 1 covering the user H. Figure 5 shows the bedding 1 viewed from the head side of the user H using the bedding 1, along the first direction D1. The dashed line shown in Figure 5 indicates the surface 3b of the backing fabric 3 that is in contact with the user H. The dashed lines located at the end of the bedding 1 in the second direction D2, rather than the dashed line showing surface 3b, indicate the inclined partition 5 and the auxiliary partition 8. By providing the inclined partition 5 and the auxiliary partition 8 on the bedding 1, the length of the shoulder covering portion 7 in the second direction D2 can be increased.

[0057] Refer to Figure 1 again. The distance t2 between vertex K of the bedding 1 and intersection point P is shorter than the distance t3 between intersection point P and intersection point Q. Intersection point Q is the intersection of the extension of the third partition 4c (straight line L) and the fourth side 1d. Distance t2 is, for example, 5 cm or more and 15 cm or less. Distance t3 is, for example, 7 cm or more and 17 cm or less.

[0058] The partition section 4 has a pair of fourth partition sections 4d. The fourth partition sections 4d are located in the second section B. The fourth partition sections 4d are adjacent to the second side 1b of the bedding 1. The ends 4e of the fourth partition sections 4d are connected to the first partition section 4a, which is located in the center of the second direction D2. One of the fourth partition sections 4d is connected to the third side 1c of the bedding 1, and the other fourth partition section 4d is connected to the fourth side 1d. Each of the pair of fourth partition sections 4d is inclined with respect to the second partition section 4b. The pair of fourth partition sections 4d extend away from each other as they move from the ends 4e of the fourth partition sections 4d toward the virtual reference line N.

[0059] In the second part B, the distance d1 from the second side 1b extending in the second direction D2 to the fourth partition section 4d adjacent to the second side 1b along the first direction D1 is narrower than the distance d2 between the pair of second partition sections 4b that sandwich the virtual reference line N in the first direction D1. The distance d1 narrows as it approaches the center of the bedding 1 in the second direction D2.

[0060] Because the gap d1 is narrower than the gap d2, the bedding 1 can be made less likely to move at its edges. Figure 6(a) is a plan view showing the bedding 1X together with the lower body of user H, which is a reference example when the fourth partition 4d is not inclined with respect to the second partition 4b. Figure 6(b) is an enlarged plan view of the lower body of user H when the bedding 1 according to this embodiment covers user H's body.

[0061] In the bedding 1X, the partition portion 4dx adjacent to the second side 1b extends along the second direction D2. The space formed around the user H's feet when the partition portion 4dx is present is larger than the space formed around the user H's feet when the fourth partition portion 4d is present. Therefore, gaps are likely to form at the edges of the bedding 1X, which may reduce the heat retention of the bedding 1X.

[0062] In the bedding 1, the user H's feet and the fourth partition 4d are positioned parallel to each other, thus reducing the space formed around the user H's feet when the fourth partition 4d is present. "Parallel" includes not only strictly parallel objects but also cases where two objects extend in the same direction, or are approximately parallel.

[0063] The lining fabric 3 has multiple tucks T. Figure 2(b) is a schematic diagram showing the outer fabric 2, lining fabric 3, and gusset fabric 6 in the tuck T. As shown in Figure 2(b), the gusset fabric 6 is folded in the tuck T. For example, a tuck T is provided on the lining fabric 3. A "tuck" indicates a place where a part of the fabric is folded and sewn in place. By providing tucks, the bedding can be given a three-dimensional shape. Tucks can be used to shape the bedding and improve its heat retention. Tucks are sometimes called eased stitches or pinched quilts.

[0064] A tuck T is formed, for example, by folding the backing fabric 3, which has a larger area than the fronting fabric 2. A tuck T is formed by folding the backing fabric 3 in a first direction D1 or a second direction D2. As shown in Figure 1, a tuck T is provided at the intersection of the first side 1a and the inclined partition 5. A tuck T is provided at the intersection of the second side 1b and the first partition 4a. A tuck T is provided at the intersection of the third side 1c and the second partition 4b. A tuck T is provided at the intersection of the fourth side 1d and the second partition 4b.

[0065] As described above, when the lining fabric 3 is not sewn to the outer fabric 2, the area of ​​the lining fabric 3 is larger than the area of ​​the outer fabric 2. However, when the outer fabric 2 and lining fabric 3 are sewn to each other, the area of ​​the outer fabric 2 may be larger than the area of ​​the lining fabric 3 due to the provision of tucks T (see Figure 2(a)).

[0066] The tack T is provided, for example, on the edge 3a of the backing fabric 3. When viewed from a third direction D3, the tack T is, for example, polygonal (triangular in one example). The length of the portion of the tack T that follows the edge 2a of the fronting fabric 2 (edge ​​3a of the backing fabric 3) is shorter than the length of the portion of the tack T that follows the first partition 4a (or second partition 4b). The length of the portion of the tack T that follows the edge 2a of the fronting fabric 2 is, for example, 1 cm or more and 5 cm or less. The length of the portion of the tack T that follows the first partition 4a is, for example, 5 cm or more and 10 cm or less.

[0067] Some of the multiple tucks T are provided on the outside of the shoulder covering portion 7. The tucks T are provided near both ends of the second direction D2 of the bedding 1 relative to the pair of inclined partition portions 5. By providing the tucks T on the outside of the shoulder covering portion 7, the bulge of the bedding 1 in the shoulder covering portion 7 can be increased, and the area of ​​the shoulder covering portion 7 can be widened.

[0068] Next, the manufacturing method of the comforter 1 will be described. Multiple gusset fabrics 6, which will form partitions 4, are sewn onto the back fabric 3 (sewing step). The front fabric 2 is placed on top of the back fabric 3 and the multiple gusset fabrics 6 (overlapping step). The multiple gusset fabrics 6 and the back fabric 3 are sewn onto the front fabric 2 (sewing step). The multiple gusset fabrics 6 include a pair of inclined gusset fabrics 9. The inclined gusset fabrics 9 are formed on the comforter 1 so that the pair of inclined gusset fabrics 9 are aligned along the second direction D2. The pair of inclined gusset fabrics 9 are formed so that they are inclined with respect to the second direction D2 in the first part A. A tuck T is formed on the edge 3a of the back fabric 3. The internal space S (see Figure 2) defined by the multiple gusset fabrics 6 and the inclined gusset fabrics 9 is filled with stuffing. The edge 2a of the front fabric 2 and the edge 3a of the back fabric 3 are sewn to each other. After the above steps, the series of steps in the manufacturing method of the bedding 1 is completed.

[0069] Next, the effects and advantages obtained from the bedding 1 according to this embodiment will be described. The bedding 1 comprises a front fabric 2, a back fabric 3, and a plurality of partition sections 4. The internal space S, defined by the front fabric 2 and the back fabric 3 and partitioned by the plurality of partition sections 4, can be filled with stuffing. The plurality of partition sections 4 include a pair of inclined partition sections 5. The pair of inclined partition sections 5 are inclined with respect to a second direction D2. The pair of inclined partition sections 5 extend so as they move away from each other toward a virtual reference line N. The bedding 1 has a shoulder covering section 7 between the pair of inclined partition sections 5 that accommodates the shoulders of the user H. Because the pair of inclined partition sections 5 are inclined so as they move away from each other toward a virtual reference line N, the partition sections 4 can conform to the shape of the user H's body, making it difficult for the bedding 1 to move away from the user H's body.

[0070] The shoulder covering portion 7, which accommodates the user H's shoulders, is positioned between a pair of inclined partition portions 5. This prevents the inclined partition portions 5 from being positioned directly over the user H's body, reducing the possibility of the bedding 1 being lifted when the user H turns over in their sleep. Consequently, the gap formed between the user H's body and the bedding 1 can be reduced, maintaining the heat retention properties of the bedding 1.

[0071] Furthermore, each of the pair of inclined partition sections 5 is inclined at an angle of 20° or more and 60° or less with respect to the second direction D2. By inclining the inclined partition section 5 at an angle of 20° or more with respect to the second direction D2, the shape of the inclined partition section 5 in a plan view can be made to conform to the user H's body, thereby improving the fit. By inclining the inclined partition section 5 at an angle of 60° or less with respect to the second direction D2, the amount of cold air entering the bedding 1 from between the pair of inclined partition sections 5 can be reduced.

[0072] Furthermore, each of the multiple partition sections 4 includes an auxiliary partition section 8 that extends from at least one of the pair of inclined partition sections 5 to the edge 2a of the front fabric 2 and the edge 3a of the back fabric 3. When the bedding 1 covers the user H's body, the bedding 1 curves in the third direction D3, and the third side 1c and fourth side 1d of the bedding 1 may be oblique to the first direction D1. At this time, the auxiliary partition section 8 acts as a guide to stretch the inclined partition section 5 in the width direction of the user H's body. In this way, the auxiliary partition section 8 can function as a guide.

[0073] Furthermore, each of the multiple partition sections 4 includes a gusset fabric 6. The width of the gusset fabric 6 located in the center of the second direction D2 is greater than the width of the gusset fabric 6 located at the end of the second direction D2. The larger width of the gusset fabric 6 located in the center of the second direction D2 makes it easier to make the center of the bedding 1 bulge. This makes it possible to maintain warmth for the user H covered by the bedding 1 more reliably. The smaller width of the gusset fabric 6 located at the end 1f of the second direction D2 makes it possible to lower the center of gravity of the end 1f of the bedding 1. This makes it possible to reduce the gap formed between the bedding 1 and the user H.

[0074] Furthermore, some of the multiple partition sections 4 extend in the second direction D2. In the second section B, the distance d1 from the second side 1b extending in the second direction D2 to the fourth partition section 4d adjacent to the second side 1b along the first direction D1 is narrower than the distance between the pair of second partition sections 4b that sandwich the virtual reference line N in the first direction D1. In this case, the comforter 1 can be made less likely to move between the second side 1b of the comforter 1 and the fourth partition section 4d adjacent to the second side 1b. Therefore, the gap formed between the comforter 1 and the user H at the second side 1b of the comforter 1 can be reduced.

[0075] Furthermore, the length of the backing fabric 3 in the first direction D1 is longer than the length of the fronting fabric 2 in the first direction D1. The length of the backing fabric 3 in the second direction D2 is longer than the length of the fronting fabric 2 in the second direction D2. The backing fabric 3 has multiple tucks T. By providing tucks T, a specific part of the bedding 1 can be made to bulge. This makes it more difficult for the bedding 1 to separate from the user H's body.

[0076] Furthermore, some of the multiple tacks T are provided on the edge 3a of the backing fabric 3. By providing the tacks T on the edge 3a of the backing fabric 3, the tacks T can be made less noticeable.

[0077] Furthermore, some of the multiple tucks T are located on the outside of the shoulder covering portion 7. This allows for a wider area between the pair of inclined partition portions 5.

[0078] Furthermore, the method for manufacturing the bedding 1 described above is used to manufacture the bedding 1 described above. Therefore, the same effects as those of the bedding 1 described above can be obtained from this method for manufacturing the bedding 1.

[0079] (Second Embodiment) The following describes a bedding set of a different embodiment from the bedding set 1 described above. Some of the components of the bedding set of each embodiment described below are the same as those described above for parts of bedding set 1. Therefore, in the following, components that are the same as those described above will be denoted by the same reference numerals and their descriptions will be omitted as appropriate. Figure 7 is a plan view showing bedding set 1A according to the second embodiment.

[0080] The second embodiment of the bedding 1A differs from the first embodiment of the bedding 1 in that it has more first partitions 4a than the bedding 1 of the first embodiment. The bedding 1A differs from the bedding 1 in that it has tucks TA in addition to tucks T. The bedding 1A differs from the bedding 1 in that it does not have a fourth partition 4d. The bedding 1A differs from the bedding 1 in that it has a shoulder covering portion 7A that has a different shape from the shoulder covering portion 7 described above.

[0081] The bedding 1A has multiple (two in this example) first partition sections 4a in the center of the second direction D2. The distance y3 between the third side 1c and the first partition section 4a adjacent to the third side 1c is shorter than the distance y4 between the intersection point V and the end 5b. The intersection point V is the intersection of the extension line extending along the first partition section 4a adjacent to the third side 1c and the first side 1a.

[0082] Distance y4 is longer than the distance y5 between end 5b and intersection W. Intersection W is the intersection of the second first partition 4a from one side in the second direction D2 and the first side 1a. The distance y6 between the two intersections W is longer than distances y3, y4, and y5. Distance y3 is, for example, 20 cm or more and 30 cm or less. Distance y4 is, for example, 20 cm or more and 40 cm or less. Distance y5 is, for example, 1 cm or more and 10 cm or less. Distance y6 is, for example, 30 cm or more and 45 cm or less.

[0083] The bedding 1A includes a fifth partition 4g. The fifth partition 4g is located in the first part A. The fifth partition 4g connects a pair of inclined partitions 5 to each other. The fifth partition 4g extends in the second direction D2. The fifth partition 4g is adjacent to the first side 1a of the bedding 1A. The fifth partition 4g is located between the first side 1a and the second partition 4b in the first direction D1.

[0084] The distance d3 between the fifth partition 4g and the first side 1a is shorter than the distance d4 between the fifth partition 4g and the second partition 4b adjacent to the fifth partition 4g. The distance d3 is, for example, 15 cm or more and 25 cm or less. The distance d4 is, for example, 20 cm or more and 30 cm or less. The shoulder covering portion 7A is the portion enclosed by the pair of inclined partitions 5, the fifth partition 4g, and the first side 1a.

[0085] Multiple tucks TA are provided in locations other than the edges 3a of the backing fabric 3. For example, a tuck TA is provided in the second partition 4b. A tuck TA is provided between two intersection points X aligned in the second direction D2. Intersection points X are the points where the first partition 4a and the second partition 4b intersect. A tuck TA is located, for example, at the midpoint of the line segment connecting the two intersection points X. By providing tucks TA in the second partition 4b, an uneven surface can be formed on the backing fabric 3. This makes it more difficult for warm air between the bedding 1A and the user H to escape to the outside.

[0086] Figure 8 is a cross-sectional view along the line VIII-VIII shown in Figure 7. Figure 8 shows the gusset fabric 6 in a cross-section along the second direction D2 and the third direction D3. The width m3 of the gusset fabric 6 located at the center 1e in the second direction D2 is greater than the width m4 of the gusset fabric 6 located at the end 1f in the second direction D2. The width m3 is, for example, 6 cm or more and 15 cm or less. The width m4 is, for example, 1 cm or more and 10 cm or less. In the cross-section of the bedding 1A along the second direction D2 and the third direction D3, the internal space SA defined by the front fabric 2 and the back fabric 3 is, for example, trapezoidal.

[0087] Refer to Figure 7 again. The partition 4A of the bedding 1A includes a sixth partition 4h. The sixth partition 4h is located in the first part A. The sixth partition 4h is positioned in the center of the shoulder covering 7A in the second direction D2. The sixth partition 4h extends in the first direction D1. One end of the sixth partition 4h is connected to the first side 1a of the bedding 1A. The other end of the sixth partition 4h is connected to the fifth partition 4g. The sixth partition 4h is, for example, straight. The shoulder covering 7A is partitioned by the sixth partition 4h.

[0088] Figure 9 is a cross-sectional view along the line IV-IV shown in Figure 7. Figure 9 schematically shows a cross-section of the shoulder covering portion 7A along the second direction D2 and the third direction D3, and the head of the user H. The sixth partition portion 4h is the sixth gusset fabric 6h. The width m5 of the sixth gusset fabric 6h in the third direction D3 is smaller than the width m3 of the first gusset fabric 6a in the third direction D3. The width m5 of the sixth gusset fabric 6h is, for example, 1 cm or more and 10 cm or less.

[0089] Because the width m5 of the sixth gusset fabric 6h is smaller than the width m3 of the first gusset fabric 6a, the amount of padding in the center of the shoulder covering portion 7A in the second direction D2 can be reduced. This prevents the area around the mouth of the user H covered by the bedding 1A from being compressed. The weight of the padding in the shoulder covering portion 7A may be lighter than the weight of the padding in the other sections.

[0090] As described above, in the bedding 1A according to the second embodiment, some of the multiple tucks (tuck TA) are provided in locations other than the edge 3a of the backing fabric 3. In this case, the tuck TA can create an uneven surface on the backing fabric 3 of the bedding 1A that faces the user H's body. This uneven surface can further reduce the gap formed between the bedding 1A and the user H.

[0091] (Third embodiment) Figure 10 is a plan view showing a comforter 1C according to the third embodiment. The comforter 1C has a partition 4C that is different in shape from the partition 4 of the comforter 1. The comforter 1C differs from the comforter 1 in that the filling is made of synthetic fibers. The filling that fills the internal space of the comforter 1C is polyester fiberfill, polyester granular fiberfill, or a resin mesh material, etc. The filling may be a blend of natural materials and synthetic fibers. The filling may be, for example, a silk blend or a wool blend.

[0092] The multiple partition sections 4C include a pair of first partition sections 4Ca, a second partition section group 4CB including a plurality of second partition sections 4Cb, a third partition section 4Cc, a fourth partition section 4Cd, and a pair of inclined partition sections 5C. The first partition section 4Ca extends in a first direction D1. The first partition section 4Ca is, for example, curved. The first partition section 4Ca is curved so as it approaches a virtual reference line N, it protrudes towards the center of the bedding 1C.

[0093] The second partition group 4CB is located between a pair of first partitions 4Ca. The partition 4C has multiple (four in one example) second partition groups 4CB. The multiple second partition groups 4CB are aligned in the second direction D2. The multiple second partition groups 4CB are arranged symmetrically with respect to the virtual reference line N.

[0094] The second partition group 4CB includes a plurality of second partitions 4Cb aligned in the first direction D1. The second partitions 4Cb are inclined with respect to the first direction D1 and the second direction D2. A pair of second partitions 4Cb aligned in the second direction D2 are inclined to approach each other as they move toward a virtual reference line N. The second partitions 4Cb are, for example, linear.

[0095] The pair of inclined partitions 5C do not intersect with the edges 2a of the front fabric 2 and the edges 3a of the back fabric 3. The ends 5Cb of the pair of inclined partitions 5C are separated from the edges 2a of the front fabric 2 and the edges 3a of the back fabric 3. The pair of inclined partitions 5C may intersect with the edges 2a of the front fabric 2 and the edges 3a of the back fabric 3. In this case, the ends 5Cb of the pair of inclined partitions 5C may be sewn together with the edges 2a and 3a.

[0096] The third partition section 4Cc is located between a pair of inclined partition sections 5C. The third partition section 4Cc connects the ends 5Cb of the pair of inclined partition sections 5C. The third partition section 4Cc is aligned with the first partition section 4Ca and the second partition section 4Cb in the first direction D1. The third partition section 4Cc extends in the second direction D2. The third partition section 4Cc is, for example, linear.

[0097] The fourth partition 4Cd is located opposite the pair of inclined partitions 5C when viewed from the first partition 4Ca and the second partition 4Cb. The fourth partition 4Cd is aligned with the first partition 4Ca and the second partition 4Cb in the first direction D1. The fourth partition 4Cd has a portion along the second direction D2 and a portion inclined with respect to the second direction D2. The fourth partition 4Cd has a pair of these inclined portions, and the pair of these inclined portions are aligned in the second direction D2. The central portion of the fourth partition 4Cd extends in the second direction D2. Both ends of the fourth partition 4Cd (the inclined portions) extend diagonally with respect to the first direction D1 and the second direction D2 toward the edges 2a, 3a and the virtual reference line N. The pair of ends of the fourth partition 4Cd are inclined to move away from each other as they move toward the virtual reference line N.

[0098] As an example different from Figure 10, the pair of first partitions 4Ca may be curved so as they move away from each other from the center of the bedding 1C as they move toward the virtual reference line N. The first partitions 4Ca may be straight. The second partition 4Cb does not have to be inclined toward the first direction D1 and the second direction D2. That is, the second partition 4Cb may extend toward either the first direction D1 or the second direction D2.

[0099] In a comforter 1C whose filling is made of synthetic fibers, for example, the filling may be filled into the internal space, and a quilted pattern may be formed by a comforter machine with the internal space filled with the filling. In this case, the partition 4C is formed by the quilted pattern. The comforter 1C may also be formed by sewing gusset fabric to the outer fabric 2 and the inner fabric 3, and filling the internal space partitioned by the gusset fabric with filling.

[0100] (Fourth Embodiment) Figure 11 is a plan view showing a comforter 1D according to the fourth embodiment. The comforter 1D includes a partition 4D that is different from the partition 4C described above. The partition 4D has a plurality of first partitions 4Da and a second partition group 4DB which includes a plurality of second partitions 4Db. A plurality of first partitions 4Da are provided in each of the areas where the aforementioned first partition 4Ca is formed.

[0101] The partition section 4D has a pair of second partition section groups 4DB. The second partition section groups 4DB are located between a pair of first partition sections 4Da. The pair of second partition section groups 4DB are aligned in a first direction D1. The pair of second partition section groups 4DB straddle a virtual reference line N. The second partition section group 4DB includes a plurality of second partition sections 4Db. The second partition sections 4Db extend in a second direction D2. The second partition sections 4Db are, for example, curved. The second partition sections 4Db are curved so as to project toward the center of the bedding 1D.

[0102] (Fifth embodiment) The bedding according to the above embodiment can be manufactured in various sizes depending on the user H's physique, the number of users, or the size of the bed. For example, the bedding can be made in single, semi-double, double, queen, or king sizes, according to the bedding standards.

[0103] For example, the size of the bedding can be changed by adjusting the length of the second direction D2 of the bedding. In this case, the number of second directions D2 in the first section C1 may increase. For example, in double, queen, and king sizes, the bedding may be configured to accommodate use by two people.

[0104] Figure 12 is a plan view showing a comforter 1E according to the fifth embodiment. Figure 13 is a cross-sectional view along the line XIII-XIII shown in Figure 12. The comforter 1E comprises a plurality of shoulder coverings 7. As an example, the comforter 1E comprises a pair of shoulder coverings 7. The pair of shoulder coverings 7 are arranged along a second direction D2. A first partition 4a located in the center of the second direction D2 is connected to an inclined partition 5.

[0105] The distance y7 from the vertex K of the bedding 1E to the end 5b of the inclined partition 5 closest to the vertex K is longer than the distance y8 between the end 5b and the intersection R. Distance y7 is, for example, 20 cm or more and 60 cm or less. Distance y8 is, for example, 10 cm or more and 30 cm or less. Distance y8 being shorter than distance y7 makes it easier for the user H's shoulders to fit into the shoulder covering portion 7. On the first side 1a, the distance between a pair of shoulder covering portions 7 is, for example, 10 cm or more and 50 cm or less. Between one shoulder covering portion 7 and the other shoulder covering portion 7, the distance y9 between the ends 5b of adjacent inclined partition portions 5 is, for example, 30 cm or more and 40 cm or less.

[0106] The partition 4E of the bedding 1E has a seventh partition 4j. The seventh partition 4j is located in the second part B. The seventh partition 4j is located between a pair of fourth partitions 4d. The seventh partition 4j is connected to the ends 4e of the pair of fourth partitions 4d. The seventh partition 4j extends in the second direction D2.

[0107] Figure 13 shows the duvet 1E in cross-section along the second direction D2 and the third direction D3. The width m3 of the gusset fabric 6 (first gusset fabric 6a) intersecting with the seventh partition portion 4j of the duvet 1E is greater than the width m4 of the gusset fabric 6 (first gusset fabric 6a) located at the end 1f in the second direction D2 of the duvet 1E. The width m3 is, for example, 6 cm or more and 15 cm or less. The width m4 is, for example, 1 cm or more and 10 cm or less.

[0108] As described above, the bedding 1E according to the fifth embodiment includes a pair of shoulder coverings 7. The pair of shoulder coverings 7 are arranged along the second direction D2. In this case, even if two users H sleep side by side along the second direction D2, the shoulder coverings 7 are positioned on each user H's shoulder, preventing cold air from entering through the gap formed between the user H's body and the bedding 1E. Even when the bedding 1E is used by only one user H, the same effect can be achieved by using one of the pair of shoulder coverings 7.

[0109] The embodiments of the bedding according to this disclosure have been described above. However, the bedding according to this disclosure is not limited to the embodiments described above and may be modified as long as the gist of the claims is not altered. That is, the shape, size, material, number and arrangement of the bedding according to this disclosure, as well as the content and sequence of steps in the manufacturing method of the bedding, can be appropriately changed within the scope of the gist described above.

[0110] For example, in the embodiment described above, an example was described in which the pair of inclined partitions 5 are straight. However, the pair of inclined partitions may be curved to match the shape of the user's shoulders and arms. In this case, the inclined partitions can be made even less likely to move away from the user's body.

[0111] In the embodiment described above, an example was described in which the ends 5b of the pair of inclined partitions 5 are connected to the edge 2a of the front fabric 2 and the edge 3a of the back fabric 3. However, the ends of the pair of inclined partitions may be located at a distance from the edge 2a of the front fabric 2 and the edge 3a of the back fabric 3.

[0112] In the embodiment described above, an example was described in which one internal space S is defined between the outer fabric 2 and the inner fabric 3. However, multiple internal spaces may be defined between the outer fabric 2 and the inner fabric 3. For example, multiple internal spaces may be arranged in a third direction D3. In this case, the bedding may be formed by multiple layers.

[0113] Next, a bedding set according to an embodiment will be described. Note that the present invention is not limited to the following embodiment. The bedding set according to the embodiment is the same bedding set as the bedding set 1 described above.

[0114] A comforter according to one embodiment of the present invention was prepared as an example. In the comforter of the example, 1.2 kg of 93% Hungarian white mother goose down (HUMWG) was used as the filling. For comparison with the comforter of the example, a comforter with a conventional 4x5 grid-like quilt was prepared as a comparative example. In the comparative example comforter, 1.2 kg of the same 93% Hungarian white mother goose down as in the comforter of the example was used as the filling.

[0115] The following describes various experiments using the bedding of the example and the bedding of the comparative example. Figure 14 shows the results of the skin conformity test. As shown in Figure 14, in order to evaluate the skin conformity (drape) of the bedding to the user's body, the bedding was placed over a cylindrical object, and the cross-sectional areas of the gaps E1 and E2 between the object and the bedding were measured. These cross-sectional areas represent the cross-sectional areas of the gaps E1 and E2 in a plane perpendicular to the direction in which the axis of the cylindrical object extends. The smaller the cross-sectional area, the higher the adhesion to the user's body and the better the fit. Figure 14(a) shows the bedding of the example. Figure 14(b) shows the bedding of the comparative example.

[0116] In the example of the bedding, the cross-sectional area of ​​the gap E1 is 387 cm². 2 In contrast, in the comparative example of the bedding, the cross-sectional area of ​​the gap E2 was 423 cm². 2 The results indicated that the bedding in the example conformed more closely to the shape of the user's body compared to the bedding in the comparative example, suggesting a structure that minimizes the formation of gaps between the user's body and the bedding.

[0117] Figure 15 shows the results of photographing a comforter using thermography. The comforter was placed on a thermal mannequin that simulates the thermal properties of the human body, and the surface temperature distribution of the comforter was photographed with a thermographic camera. Thermography analyzes the infrared radiation emitted from the surface of an object and visualizes the temperature distribution with color. In Figure 15, high-temperature areas are shown with high-brightness colors, and low-temperature areas are shown with low-brightness colors.

[0118] Figure 15(a) shows the bedding of the embodiment. Figure 15(b) shows the bedding of the comparative example. In the bedding of the comparative example, heat leakage to the outside was observed along the partition. In contrast, in the bedding of the embodiment, heat leakage from the partition was suppressed, suggesting that heat was efficiently retained inside the bedding.

[0119] Figure 16 is a table showing the results of the heat retention test for bedding. The heat retention of the bedding was evaluated using a thermal mannequin. The heat retention test was performed using the thermal mannequin method. The measurement environment was set to a room temperature of 20°C and a relative humidity (RH: Relative Humidity) of 65%. "Relative humidity" is an index that indicates the percentage of water vapor contained in the air. The surface temperature of the thermal mannequin, which corresponds to the temperature of human skin, was set to 33°C.

[0120] For evaluating heat retention, the clo value, which represents the insulation and heat retention performance of clothing and bedding, was used. A higher clo value indicates better heat retention. Figure 16(a) shows the bedding of the example. Figure 16(b) shows the bedding of the comparative example. In the bedding of the example, the clo value for the entire body excluding the face and head was 3.45, while in the bedding of the comparative example it was 2.92, suggesting that the bedding of the example has superior heat retention overall.

[0121] The clo value of the covering portion of the example bedding was 4.90, while the clo value of the comparative example bedding was 3.92. The clo value of the example bedding was 1 higher than that of the comparative example bedding, indicating that the example bedding exhibited superior heat retention. The clo value of the shoulder of the example bedding was 4.52, while the clo value of the comparative example bedding was 4.12. This suggests that the shoulder covering portion of the present invention suppresses shifting and lifting of the bedding due to the user turning over in their sleep, effectively preventing cold air from entering from the shoulders.
