Description
[Technical field]
[0001] The present disclosure relates to a cushion body against which a user's body rests, and a method for manufacturing the cushion body. [Background technology]
[0002] Patent Document 1 describes a bedding. The bedding has a first thick sheet, a second thick sheet, and a third thick sheet that are overlapped with each other. The bedding is rectangular in shape. One side of the bedding is an opening, and the other three sides of the bedding are sewn together with piping. This bedding can be used as a blanket with the entire three-ply first thick sheet, second thick sheet, and third thick sheet.
[0003] The bedding can also be used as a sleeping bag by using the two openings. Of the first, second and third thick sheets, one can be used as a blanket and the remaining two can be used as sheets. Of the first, second and third thick sheets, two can be used as blankets and one can be used as a sheets.
[0004] Patent Document 2 describes a thermal insulation cloth. Two thermal insulation cloths having the same shape are overlapped and the periphery is sewn together, and an opening is formed from the surface to the overlapping surface of the two thermal insulation cloths. One of the two thermal insulation cloths is sandwiched between the upper cloth and the middle cloth, and the other of the two thermal insulation cloths is sandwiched between the middle cloth and the lower cloth. The openings are provided in the upper cloth and the lower cloth, and can be opened and closed by a fastening device such as a slide fastener. By pulling out the overlapping surfaces of the two thermal insulation cloths from the openings, it is possible to use the two thermal insulation cloths with the front and back reversed.

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 6-77639 [Patent Document 2] Publication No. 57-157279 Summary of the Invention [Problem to be solved by the invention]
[0006] In the above-mentioned thermal cloth, the upper and lower cloths have openings that can be opened and closed by fasteners such as slide fasteners. In this case, the cloth must be cut and a slide fastener or the like must be attached to the cut portion, so it is expected that the openings cannot be easily formed. Furthermore, the openings must be opened by fasteners with the surface with the openings facing upwards, which may cause a problem that it is difficult to insert a hand into the opening and pull out the fabric.
[0007] The present disclosure aims to provide a cushion body in which an opening can be easily formed and fabric can be easily pulled out by inserting a hand into the opening, and a method for manufacturing the cushion body. [Means for solving the problem]
[0008] (1) The cushion body according to the present disclosure has a first side extending in a first direction and a second side extending in a second direction intersecting the first direction, and includes a laminated fabric, which is a plurality of fabrics laminated in a third direction intersecting both the first and second directions, and a hem portion bundling the outer edges of the plurality of fabrics when viewed from the third direction. The plurality of fabrics are a first fabric, a second fabric, a third fabric, and a fourth fabric, and the first fabric, the second fabric, the third fabric, and the fourth fabric are arranged in this order along the third direction. The first fabric is exposed on one side of the cushion body in the third direction, and the fourth fabric is exposed on the other side of the cushion body in the third direction. The cushion body has an opening through which a hand can be inserted between the second fabric and the third fabric from the outside of the cushion body. By inserting a hand into the opening and pulling out the second fabric and the third fabric from the opening, the second fabric can be exposed on one side of the third direction and the third fabric can be exposed on the other side of the third direction. When viewed along the third direction, the opening extends along the first side. When viewed along the third direction, one end of the opening in the first direction is located closer to the center in the first direction than one end of the first side in the first direction, and the other end of the opening in the first direction is located closer to the center in the first direction than the other end of the first side in the first direction.
[0009] This cushion body has a laminated fabric made of a plurality of fabrics and a hem portion bundling the outer edges of the plurality of fabrics when viewed from the third direction. The plurality of fabrics include a first fabric, a second fabric, a third fabric, and a fourth fabric, and the first fabric, the second fabric, the third fabric, and the fourth fabric are arranged in this order along the third direction. The cushion body has an opening through which a hand can be inserted between the second fabric and the third fabric from the outside of the cushion body. The second fabric and the third fabric can be exposed by inserting a hand into the interior of the cushion body through the opening and pulling out the second fabric and the third fabric from the opening. At this time, the second fabric faces one side in the third direction, and the third fabric faces the other side in the third direction. The opening extends along a first side extending in the first direction. Since the opening is formed in the side of the cushion body, it is not necessary to cut the fabric, and therefore the opening can be easily formed. One end of the opening in the first direction is located closer to the center in the first direction than one end of the first side in the first direction, and the other end of the opening in the first direction is located closer to the center in the first direction than the other end of the first side in the first direction. Therefore, the opening is formed at a position that does not reach both ends of the first side. However, if the opening is formed at a position that reaches the end of the side, sewing may be difficult and it may be difficult to pull out the fabric from the opening. In contrast, in this cushion body, the opening is formed in the middle of the first side, so sewing can be easily performed and the fabric can be easily pulled out from the opening. Therefore, the work of pulling out the second and third fabrics and the work of pulling out the first and fourth fabrics can be easily performed by inserting a hand into the opening.
[0010] (2) In the above (1), the laminated fabric may have a rectangular shape when viewed along the third direction. The first side may be a short side of the laminated fabric having a rectangular shape, and the second side may be a long side of the laminated fabric having a rectangular shape. In this case, one end of the opening in the first direction is located closer to the center in the first direction than one end of the short side in the first direction, and the other end of the opening in the first direction is located closer to the center in the first direction than the other end of the short side in the first direction. Therefore, by forming the opening in the middle of the short side, the length of the opening can be minimized. When the length of the opening is short, there is an advantage that the multiple fabrics constituting the laminated fabric are less likely to shift. Therefore, when the opening is formed in the middle of the short side, the multiple fabrics can be made less likely to shift, which can improve the sleeping comfort.
[0011] (3) In the above (1) or (2), the cushion body may have contents accommodated in at least one of the internal spaces between the first and second fabrics and between the third and fourth fabrics. In this case, the heat retention of the cushion body is improved, making it possible to use the cushion body as a futon.
[0012] (4) In any of the above (1) to (3), the hem portion may include a first hem cloth bundling the first fabric and the second fabric, and a second hem cloth bundling the third fabric and the fourth fabric. In this case, one hem cloth bundling the outer edges of the two fabrics. Therefore, even if a thick fabric is included among the first fabric, the second fabric, the third fabric, and the fourth fabric, sewing can be performed more easily than when one hem cloth bundling three or more fabrics. Therefore, the types of fabrics used as the first fabric, the second fabric, the third fabric, and the fourth fabric can be increased, resulting in a highly versatile cushion body. Furthermore, when one hem cloth bundling two fabrics, it is easier to insert a hand into the opening and pull out the fabric than when one hem cloth bundling three or more fabrics.
[0013] (5) In the above (4), the cushion body may have a first sewn part where the first fabric, the second fabric, and the first hem cloth are sewn together, a second sewn part where the third fabric, the fourth fabric, and the second hem cloth are sewn together, and a third sewn part where the first hem cloth and the second hem cloth are sewn together. In this case, by providing the first sewn part, the second sewn part, and the third sewn part, the outer edge of the laminated fabric can be firmly sewn.
[0014] (6) A method for manufacturing a cushion body according to the present disclosure is a method for manufacturing a cushion body including a laminated fabric having a first side extending in a first direction and a second side extending in a second direction intersecting the first direction, and being a plurality of fabrics laminated in a third direction intersecting both the first and second directions, and a hem portion bundling the outer edges of the plurality of fabrics when viewed from the third direction. The plurality of fabrics are a first fabric, a second fabric, a third fabric, and a fourth fabric, and the hem portion includes a first hem cloth and a second hem cloth. The method for manufacturing the cushion body includes a first step of bundling the outer edge of the first fabric and the outer edge of the second fabric with a first hem cloth while the first fabric is superimposed on the second fabric, and sewing the first fabric, the second fabric, and the first hem cloth together, a second step of bundling the outer edge of the third fabric and the outer edge of the fourth fabric with a second hem cloth while the third fabric is superimposed on the fourth fabric, and sewing the third fabric, the fourth fabric, and the second hem cloth together, and a third step of sewing the first hem cloth and the second hem cloth together while the second fabric is facing the third fabric. In the third step, the first hem cloth and the second hem cloth are sewn together in a location other than a region where an opening is formed through which a hand can be inserted between the second fabric and the third fabric from outside the cushion body, and the opening is formed between the first hem cloth and the second hem cloth in that region.
[0015] In this method for manufacturing a cushion body, the outer edge of the first fabric and the outer edge of the second fabric are bound by the first hem cloth, and the outer edge of the third fabric and the outer edge of the fourth fabric are bound by the second hem cloth. Therefore, even if a thick fabric is included in the first fabric, the second fabric, the third fabric, and the fourth fabric, sewing can be easily performed, so that the types of fabrics used as the first fabric, the second fabric, the third fabric, and the fourth fabric can be increased, as in the cushion body described above. The first fabric, the second fabric, and the first hem cloth are sewn together, the third fabric, the fourth fabric, and the second hem cloth are sewn together, and further the first hem cloth and the second hem cloth are sewn together. Therefore, the outer edges of the laminated fabrics can be sewn firmly. In this method for manufacturing a cushion body, an opening is formed between the second fabric and the third fabric from the outside of the cushion body, allowing a hand to be inserted between them. Then, one hem cloth binds the two fabrics together. Therefore, as in the cushion body described above, the work of inserting a hand into the opening and pulling out the fabric can be easily performed. Furthermore, the opening is formed between the first hem cloth and the second hem cloth, so there is no need to cut the fabric, and the opening can be easily formed. Effect of the Invention
[0016] According to the present disclosure, the opening can be easily formed, and the dough can be easily pulled out by inserting a hand into the opening. [Brief description of the drawings]

[0018] The cushion body and the manufacturing method of the cushion body according to the present disclosure will be described below with reference to the drawings. In the description of the drawings, the same or corresponding elements are given the same reference numerals, and duplicated descriptions are omitted as appropriate. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios and the like are not limited to those shown in the drawings.
[0019] The term "cushion body" refers to an object made of a flexible material. The term "cushion body" refers to, for example, an object against which the body of a user of the cushion body rests. The term "flexible material" refers to a material that has flexibility to the extent that it can be deformed by the application of an external force from the body of the user of the cushion body.
[0020] Fig. 1 is a plan view showing a cushion body 1 according to this embodiment. The cushion body 1 has a laminated fabric 10 (see Fig. 7) which is a plurality of fabrics. For example, the plurality of fabrics of the laminated fabric 10 are a first fabric 11, a second fabric 12, a third fabric 13, and a fourth fabric 14. For example, the cushion body 1 has a rectangular shape.
[0021] The cushion body 1 has a short side 1b extending along a first direction D1 and a long side 1c extending along a second direction D2 that intersects with the first direction D1. For example, the length of the short side 1b is 60 cm or more and 230 cm or less (100 cm as an example), and the length of the long side 1c is 90 cm or more and 230 cm or less (200 cm as an example).
[0022] In this case, the first direction D1 is the short side direction of the cushion body 1, and the second direction D2 is the long side direction of the cushion body 1. For example, the first direction D1 and the second direction D2 are perpendicular to each other. The cushion body 1 has a pair of short sides 1b aligned along the second direction D2 and a pair of long sides 1c aligned along the first direction D1.
[0023] The cushion body 1 has a thickness in a third direction D3 that is a direction intersecting (e.g., perpendicular to) both the first direction D1 and the second direction D2. The cushion body 1 has a hem portion 2 that bundles the outer edges of multiple fabrics when viewed from the third direction D3 (in a plan view). The hem portion 2 has a frame shape that surrounds the laminated fabric 10 when viewed from the third direction D3.
[0024] In the cushion body 1, any one of the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 can be exposed. In other words, any one of the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 can be directed vertically upward.
[0025] For example, the cushion body 1 is a mattress pad. In this case, the cushion body 1 may be attached on a mattress. The mattress is, for example, a mattress. Fig. 1 is a plan view showing a first fabric 11 of the cushion body 1. Fig. 2 is a plan view showing a fourth fabric 14 of the cushion body 1.
[0026] As shown in Figs. 1 and 2, the fourth fabric 14 has a surface facing away from the first fabric 11. That is, when the cushion body 1 with the first fabric 11 facing up is turned upside down, the fourth fabric 14 faces up. For example, among the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14, the first fabric 11 is the thinnest fabric. The fourth fabric 14 is, for example, fluffier than the first fabric 11. Details of the first fabric 11 and the fourth fabric 14 will be described later.
[0027] The cushion body 1 includes a first rubber portion 3 that fixes the cushion body 1 to bedding. The first rubber portion 3 extends in a direction inclined with respect to both the first direction D1 and the second direction D2 at a corner portion 1d of the cushion body 1 when viewed along the third direction D3. The first rubber portion 3 is, for example, strip-shaped. The first rubber portion 3 extends from a short side 1b of the cushion body 1 to a long side 1c of the cushion body 1.
[0028] The cushion body 1 is fixed onto the bedding by pulling the first rubber portion 3 and hanging the first rubber portion 3 on the bedding located under the cushion body 1. The cushion body 1 has, for example, a plurality of first rubber portions 3. The plurality of first rubber portions 3 are arranged, for example, at the four corners of the cushion body 1 when viewed from the third direction D3.
[0029] Fig. 3 is a perspective view showing the hem portion 2 and the first rubber portion 3 with the fourth fabric 14 facing upward. Fig. 4 is a perspective view showing the hem portion 2 and the first rubber portion 3 with the first fabric 11 facing upward. The hem portion 2 includes a first hem cloth 2b provided on the outer edge of the first fabric 11 and a second hem cloth 2c provided on the outer edge of the fourth fabric 14. The "outer edge" refers to the outer edge of an object when viewed along the third direction D3.
[0030] The first hem cloth 2b and the second hem cloth 2c are aligned along the third direction D3. For example, an end of the belt-shaped first rubber part 3 is sandwiched between the second hem cloth 2c and the fourth fabric 14 and sewn (by a sewn stitch) together with the second hem cloth 2c and the fourth fabric 14. In this case, the first rubber part 3 extends on the fourth fabric 14 from the second hem cloth 2c constituting the long side 1c to the second hem cloth 2c constituting the short side 1b.
[0031] The first rubber portion 3 can be transitioned from a state in which it extends above the fourth fabric 14 to a state in which it extends above the first fabric 11. More specifically, the first rubber portion 3 extending above the fourth fabric 14 is stretched to pass the first rubber portion 3 through the corner portion 1d of the cushion body 1, and the first rubber portion 3 is moved to the first fabric 11 of the cushion body 1, whereby the first rubber portion 3 transitions to a state in which it extends above the first fabric 11. As a result, the cushion body 1 is fixed on the bedding by the first rubber portion 3 with the first fabric 11 facing up, and the cushion body 1 is fixed on the bedding by the first rubber portion 3 with the fourth fabric 14 facing up.
[0032] Fig. 5 is a plan view showing the hem portion 2 of the cushion body 1 and the laminated fabric 10. As shown in Fig. 5, when viewed along the third direction D3, for example, the laminated fabric 10 has a rectangular shape. The laminated fabric 10 has a first side 10b extending in the first direction D1 and a second side 10c extending in the second direction D2. The first side 10b is a short side of the laminated fabric 10, and the second side 10c is a long side of the laminated fabric 10. The laminated fabric 10 has a pair of first sides 10b aligned in the second direction D2 and a pair of second sides 10c aligned in the first direction D1.
[0033] Fig. 6 is a diagram showing the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 of the cushion body 1. As shown in Figs. 5 and 6, the cushion body 1 has an opening 4 that allows a hand to be inserted between the second fabric 12 and the third fabric 13 from outside the cushion body 1. The opening 4 is formed between the first hem cloth 2b and the second hem cloth 2c. For example, the opening 4 is a portion where the first hem cloth 2b and the second hem cloth 2c are not sewn together, and is a portion where the fabrics (e.g., the second fabric 12 and the third fabric 13) located inside the cushion body 1 can be seen.
[0034] By inserting a hand into the opening 4 and pulling out the second fabric 12 and the third fabric 13 from the opening 4, it is possible to expose the second fabric 12 on one side (e.g., the upper side) of the third direction D3 and expose the third fabric 13 on the other side (e.g., the lower side) of the third direction D3. When viewed along the third direction D3, the opening 4 extends along the first side 10b.
[0035] When viewed along the third direction D3, one end (e.g., the left end) of the opening 4 in the first direction D1 is located closer to the center of the first direction D1 than one end of the first side 10b in the first direction D1, and the other end (e.g., the right end) of the opening 4 in the first direction D1 is located closer to the center of the first direction D1 than the other end of the first side 10b in the first direction D1.
[0036] The opening 4 is formed at a position that does not reach both ends of the first side 10b (corners 1d of the cushion body 1). That is, the opening 4 is formed in a middle portion of the first side 10b. For example, the opening 4 is formed in a region including the center of the first side 10b in the first direction D1. The opening 4 may be formed between a pair of first rubber parts 3 aligned along the first direction D1.
[0037] The length L1 of the opening 4 in the first direction D1 is shorter than the length L2 of the first side 10b. For example, the length L1 of the opening 4 in the first direction D1 is longer than the distance from the opening 4 to the corner 1d of the cushion body 1. For example, the length L1 of the opening 4 in the first direction D1 is 20 cm or more and 60 cm or less (40 cm as an example), and the distance from the opening 4 to the corner 1d of the cushion body 1 is 20 cm or more and 40 cm or less (30 cm as an example).
[0038] The opening 4 is a portion that can be opened and closed freely, and is, for example, a portion that does not have an opening and closing member (one example is a line fastener). In this case, the opening 4 can be easily formed, the hand can be easily inserted inside the opening 4, and the possibility that the opening and closing member will come into contact with the body while sleeping, etc., causing discomfort to the user of the cushion body 1 can be reduced.
[0039] The cushion body 1 includes a second rubber portion 5 located between the second fabric 12 and the third fabric 13. The second rubber portion 5 has, for example, a strip shape. The cushion body 1 includes, for example, a plurality of second rubber portions 5. The plurality of second rubber portions 5 are disposed, for example, at each of the four corners of the cushion body 1 when viewed from the third direction D3.
[0040] The second rubber portion 5 extends in a direction inclined with respect to both the first direction D1 and the second direction D2 at a position adjacent to the first rubber portion 3 when viewed from the third direction D3. The second rubber portion 5 extends from the short side 1b of the cushion body 1 to the long side 1c of the cushion body 1.
[0041] For example, when viewed along the third direction D3, the second rubber portion 5 is located between the first rubber portion 3 and a corner portion 1d of the cushion body 1. When the first fabric 11 and the fourth fabric 14 are exposed outside the cushion body 1 (for example, vertically upward and vertically downward, respectively), the second rubber portion 5 is located inside 1f of the cushion body 1. The second rubber portion 5 will be described in detail later.
[0042] Fig. 7 is a cross-sectional view taken along line AA in Fig. 5. As shown in Fig. 6 and Fig. 7, the first fabric 11, the second fabric 12, the third fabric 13 and the fourth fabric 14 are arranged in this order along the third direction D3. The first fabric 11 is exposed to one side of the cushion body 1 in the third direction D3, and the fourth fabric 14 is exposed to the other side of the cushion body 1 in the third direction D3.
[0043] The cushion body 1 includes an object 6 accommodated in an internal space S, for example, between the first fabric 11 and the second fabric 12 and / or between the third fabric 13 and the fourth fabric 14. For example, the object 6 is accommodated in the internal space S located between the third fabric 13 and the fourth fabric 14, and the object 6 is not accommodated in the internal space S located between the first fabric 11 and the second fabric 12.
[0044] For example, the contents 6 are made of a flexible material. The contents 6 are provided, for example, to enhance the heat retention of the cushion body 1. As an example, the contents 6 are cotton. In this case, it is not necessary to put nonwoven fabric in the internal space S between the third fabric 13 and the fourth fabric 14, which contributes to suppressing an increase in costs. The contents 6 may be wadding or feathers, and the type of the contents 6 is not particularly limited. In addition, the cushion body 1 may or may not have the contents 6 in the internal space S located between the first fabric 11 and the second fabric 12.
[0045] For example, the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 are different types of fabrics. As an example, the first fabric 11 is a summer fabric, the third fabric 13 is a winter fabric, and the second fabric 12 and the fourth fabric 14 are spring and autumn fabrics. The "summer fabric" is a fabric that is most suitable for use in the summer of the four seasons, and the "winter fabric" is a fabric that is most suitable for use in the winter of the four seasons. The "spring and autumn fabric" is a fabric that is suitable for use in the spring or autumn of the four seasons. The fourth fabric 14 is, for example, fluffier than the second fabric 12.
[0046] For example, the third fabric 13 has the highest thermal insulation index, the fourth fabric 14 has the second highest thermal insulation index, the second fabric 12 has the third highest thermal insulation index, and the first fabric 11 has the lowest thermal insulation index. As an example, the first fabric 11 is a cool-to-the-touch fabric, the second fabric 12 is a knit waffle fabric, the third fabric 13 is a flannel fabric, and the fourth fabric 14 is a sinker pile fabric.
[0047] However, the types of the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 are not limited to those described above. For example, at least one of the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 may be made of a boa material, broadcloth, or a cool material.
[0048] The material of each of the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 is, for example, any one of synthetic fibers, regenerated fibers, plant fibers, and animal fibers. More specifically, the material of each of the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 may be nylon, polyester, acrylic, polyurethane, polyethylene, cupra, rayon, cellulose, lyocell, cotton, linen, silk, wool, cashmere, gauze, boa, flannel, pile fabric, or brushed fabric.
[0049] For example, the first fabric 11 is made of polyester and nylon. As an example, the ratio of polyester in the first fabric 11 is 75%, and the ratio of nylon in the first fabric 11 is 25%. For example, each of the second fabric 12 and the third fabric 13 is made of polyester. For example, the fourth fabric 14 is made of polyester and rayon. As an example, the ratio of polyester in the pile portion of the fourth fabric 14 is 80%, the ratio of rayon in the pile portion of the fourth fabric 14 is 20%, and the ground yarn of the fourth fabric 14 is 100% polyester.
[0050] The cushion body 1 has, for example, a straight stitched portion 7 (sewn quilt) which is a portion where the third fabric 13 and the fourth fabric 14 are sewn together. For example, the straight stitched portion 7 is formed by a multi-needle quilting machine or a multi-head quilting machine. As an example, the cushion body 1 has a plurality of straight stitched portions 7, which extend obliquely with respect to both the first direction D1 and the second direction D2. The plurality of straight stitched portions 7 intersect with each other, for example. Note that the cushion body 1 may have a straight stitched portion where the first fabric 11 and the second fabric 12 are sewn together, or may not have a straight stitched portion.
[0051] The hem portion 2 has a first hem cloth 2b bundling the first fabric 11 and the second fabric 12, and a second hem cloth 2c bundling the third fabric 13 and the fourth fabric 14. For example, the first hem cloth 2b and the second hem cloth 2c are in a belt shape. The first hem cloth 2b is folded along a folding portion 2d extending along the longitudinal direction of the first hem cloth 2b. The first hem cloth 2b folded along the folding portion 2d sandwiches the outer edge of the first fabric 11 and the outer edge of the second fabric 12. The second hem cloth 2c is folded along a folding portion 2f extending along the longitudinal direction of the second hem cloth 2c, similar to the first hem cloth 2b. The second hem cloth 2c folded along the folding portion 2f sandwiches the outer edge of the third fabric 13 and the outer edge of the fourth fabric 14.
[0052] The cushion body 1 has a first sewn portion 8b, a second sewn portion 8c, and a third sewn portion 8d in the hem portion 2. The first sewn portion 8b is a portion where the first fabric 11, the second fabric 12, and the first hem cloth 2b are sewn together. The second sewn portion 8c is a portion where the third fabric 13, the fourth fabric 14, and the second hem cloth 2c are sewn together. The third sewn portion 8d is a portion where the first hem cloth 2b and the second hem cloth 2c are sewn together. The first sewn portion 8b, the second sewn portion 8c, and the third sewn portion 8d are formed by a strike stitch. That is, the first sewn portion 8b, the second sewn portion 8c, and the third sewn portion 8d are formed by machine sewing.
[0053] In the first sewn portion 8b, a first hem cloth 2b sandwiching the outer edges of the first fabric 11 and the second fabric 12 is sewn together with the first fabric 11 and the second fabric 12. In the second sewn portion 8c, a second hem cloth 2c sandwiching the outer edges of the third fabric 13 and the fourth fabric 14 is sewn together with the third fabric 13 and the fourth fabric 14.
[0054] For example, in the third sewn portion 8d, the first hem cloth 2b sewn in the first sewn portion 8b and the second hem cloth 2c sewn in the second sewn portion 8c are sewn together with the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14. However, in the third sewn portion 8d, only the first hem cloth 2b sewn in the first sewn portion 8b and the second hem cloth 2c sewn in the second sewn portion 8c may be sewn together.
[0055] As described above, the outer edges of the first fabric 11, the second fabric 12, the third fabric 13 and the fourth fabric 14 are sewn together by the first sewn portion 8b, the second sewn portion 8c and the third sewn portion 8d. The cushion body 1 has a first fabric group 1A consisting of the first fabric 11 and the second fabric 12 located on one side in the third direction D3, and a second fabric group 1B consisting of the third fabric 13 and the fourth fabric 14 located on the other side in the third direction D3.
[0056] The first fabric group 1A is formed by bundling the first fabric 11 and the second fabric 12 together and sewing them at the first sewing section 8b to form the first hem cloth 2b. The second fabric group 1B is formed by bundling the third fabric 13 and the fourth fabric 14 together and sewing them at the second sewing section 8c to form the second hem cloth 2c. The user of the cushion body 1 can select either the first fabric group 1A or the second fabric group 1B by changing the orientation of the cushion body 1 upside down.
[0057] In the cushion body 1, by inserting a hand into the opening 4 and pulling the second fabric 12 and the third fabric 13 out of the opening 4, the cushion body 1 transitions from a state in which the first fabric 11 and the fourth fabric 14 are exposed out of the cushion body 1 to a state in which the second fabric 12 and the third fabric 13 are exposed out of the cushion body 1. Furthermore, in the cushion body 1, by inserting a hand into the opening 4 and pulling the first fabric 11 and the fourth fabric 14 out of the opening 4, the cushion body 1 transitions from a state in which the second fabric 12 and the third fabric 13 are exposed out of the cushion body 1 to a state in which the first fabric 11 and the fourth fabric 14 are exposed out of the cushion body 1.
[0058] In this way, in the cushion body 1, the front and back of the first fabric 11 and the second fabric 12, and the front and back of the third fabric 13 and the fourth fabric 14 can be changed by inserting a hand into the opening 4 and pulling out the fabric. When the first fabric 11 and the fourth fabric 14 are exposed to the outside, the second fabric 12 and the third fabric 13 are located inside 1f of the cushion body 1, and when the second fabric 12 and the third fabric 13 are exposed to the outside, the first fabric 11 and the fourth fabric 14 are located inside 1f of the cushion body 1.
[0059] Therefore, in the cushion body 1, any one of the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 can be oriented vertically upward. Therefore, the user of the cushion body 1 can place a preferred one of the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 against his or her body.
[0060] As described above, if the first fabric 11 is a summer fabric, the third fabric 13 is a winter fabric, the second fabric 12 is a spring / autumn fabric with less fluff, and the fourth fabric 14 is a spring / autumn fabric with more fluff, the cushion body 1 can be used throughout the year by changing the surface that is exposed to the outside according to the season. Therefore, in this embodiment, there is no need to store the cushion body 1, and therefore storage space for the cushion body 1 can be eliminated.
[0061] Fig. 8 is a plan view showing a state in which the third fabric 13 of the cushion body 1 is oriented vertically upward. Fig. 9 is a plan view showing a state in which the second fabric 12 of the cushion body 1 is oriented vertically upward. Fig. 10 is an enlarged perspective view of the second rubber part 5 of Fig. 9. As shown in Figs. 8, 9 and 10, the third fabric 13 is made of a fabric that is thicker than the second fabric 12. For example, the thickness of the third fabric 13 is thicker than the thickness of the first fabric 11, the thickness of the second fabric 12 and the thickness of the fourth fabric 14. For example, the second fabric 12 is made of a fabric that is more breathable than the third fabric 13.
[0062] The cushion body 1 can be fixed onto the bedding by pulling the second rubber part 5 and hanging it on the bedding located under the cushion body 1. For example, the end of the belt-shaped second rubber part 5 is sandwiched between the second hem cloth 2c and the third fabric 13 and sewn (by a sewn stitch) together with the second hem cloth 2c and the third fabric 13. In this case, the second rubber part 5 extends on the third fabric 13 from the second hem cloth 2c constituting the short side 1b to the second hem cloth 2c constituting the long side 1c.
[0063] The second rubber part 5 can be transitioned from a state in which it extends over the third fabric 13 to a state in which it extends over the second fabric 12. More specifically, the second rubber part 5 extending over the third fabric 13 is stretched to pass the second rubber part 5 through the corner part 1d of the cushion body 1, and the second rubber part 5 is moved to the second fabric 12 of the cushion body 1, whereby the second rubber part 5 transitions to a state in which it extends over the second fabric 12. As a result, the cushion body 1 is fixed on the bedding by the second rubber part 5 with the second fabric 12 facing up, and the cushion body 1 is fixed on the bedding by the second rubber part 5 with the third fabric 13 facing up.
[0064] Next, a method for manufacturing the cushion body according to this embodiment will be described. The method for manufacturing the cushion body 1 will be described below. As shown in FIG. 7, first, the second fabric 12 is layered on the first fabric 11 (layering fabrics step). The outer edge of the first fabric 11 and the outer edge of the second fabric 12 are bound with the first hem cloth 2b (binding with the first hem cloth step). Then, the first fabric 11, the second fabric 12 and the first hem cloth 2b are sewn together to form the first sewn portion 8b (first step). This completes the first fabric group 1A consisting of the first fabric 11 and the second fabric 12 of the cushion body 1.
[0065] Meanwhile, the fourth fabric 14 is layered on the third fabric 13 (layering process). At this time, the contents 6 may be placed between the third fabric 13 and the fourth fabric 14 (containing the contents process). The outer edge of the third fabric 13 and the outer edge of the fourth fabric 14 are bound with the second hem cloth 2c (binding process with the second hem cloth). Then, the third fabric 13, the fourth fabric 14 and the second hem cloth 2c are sewn together to form the second sewn portion 8c (second process). This completes the second fabric group 1B consisting of the third fabric 13 and the fourth fabric 14 of the cushion body 1.
[0066] Next, the first fabric group 1A is placed on the second fabric group 1B so that the second fabric 12 faces the third fabric 13 (step of facing the second fabric to the third fabric). Then, the first hem cloth 2b and the second hem cloth 2c are sewn together to form the third sewn portion 8d (third step). As shown in Figs. 5, 6 and 7, in the third step, the first hem cloth 2b and the second hem cloth 2c are sewn together in a location other than the area where the opening 4 is to be formed. As a result, the part in this area where the first hem cloth 2b and the second hem cloth 2c are not sewn together forms the opening 4. Through the above steps, a series of steps in the method for manufacturing the cushion body 1 is completed.
[0067] Next, the effects obtained from the cushion body 1 according to this embodiment will be described in more detail. The cushion body 1 has a laminated fabric 10 made of a plurality of fabrics and a hem portion 2 bundling the outer edges of the plurality of fabrics when viewed from the third direction D3. The plurality of fabrics include a first fabric 11, a second fabric 12, a third fabric 13, and a fourth fabric 14, and the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 are arranged in this order along the third direction D3. The cushion body 1 has an opening 4 through which a hand can be inserted between the second fabric 12 and the third fabric 13 from the outside of the cushion body 1. The second fabric 12 and the third fabric 13 can be exposed by inserting a hand into the interior 1f of the cushion body 1 from the opening 4 and pulling out the second fabric 12 and the third fabric 13 from the opening 4.
[0068] At this time, the second fabric 12 faces one side in the third direction D3, and the third fabric 13 faces the other side in the third direction D3. The opening 4 extends along the first side 10b extending in the first direction D1. By forming the opening 4 in the side portion of the cushion body 1, it is not necessary to cut the fabric to form the opening 4, and therefore the opening 4 can be easily formed.
[0069] One end of the opening 4 in the first direction D1 is located closer to the center in the first direction D1 than one end of the first side 10b in the first direction D1, and the other end of the opening 4 in the first direction D1 is located closer to the center in the first direction D1 than the other end of the first side 10b in the first direction D1. Therefore, the opening 4 is formed at a position that does not reach both ends of the first side 10b. However, if the opening 4 is formed at a position that reaches the end of the side, sewing may be difficult and it may be difficult to pull out the fabric from the opening 4. In contrast, in the cushion body 1, the opening 4 is formed in the middle of the first side 10b, so sewing can be easily performed and the fabric can be easily pulled out from the opening 4. Therefore, it is easy to insert a hand into the opening 4 and pull out the second fabric 12 and the third fabric 13, and the first fabric 11 and the fourth fabric 14.
[0070] In this embodiment, when viewed along the third direction D3, the laminated fabric 10 has a rectangular shape, the first side 10b is a short side of the laminated fabric 10 having a rectangular shape, and the second side 10c is a long side of the laminated fabric 10 having a rectangular shape. In this case, one end of the opening 4 in the first direction D1 is located closer to the center in the first direction D1 than one end of the short side in the first direction D1, and the other end of the opening 4 in the first direction D1 is located closer to the center in the first direction D1 than the other end of the short side in the first direction D1. Therefore, since the opening 4 is formed in the middle of the short side, the length of the opening 4 can be minimized. When the length of the opening 4 is short, there is an advantage that the multiple fabrics constituting the laminated fabric 10 are less likely to shift. Therefore, when the opening 4 is formed in the middle of the short side, the multiple fabrics can be made less likely to shift, so that the sleeping comfort can be improved.
[0071] The cushion body 1 may include contents 6 accommodated in an internal space S between at least one of the first fabric 11 and the second fabric 12 and the third fabric 13 and the fourth fabric 14. In this case, the heat retention of the cushion body 1 is improved, making it possible to use the cushion body 1 as a futon.
[0072] In this embodiment, the hem portion 2 includes a first hem cloth 2b that ties together the first fabric 11 and the second fabric 12, and a second hem cloth 2c that ties together the third fabric 13 and the fourth fabric 14. In this case, one hem cloth (each of the first hem cloth 2b and the second hem cloth 2c) ties together the outer edges of the two fabrics. Therefore, even if a thick fabric is included among the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14, sewing can be performed more easily than when one hem cloth ties together three or more fabrics.
[0073] Therefore, it is possible to increase the types of fabrics used as the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14, thereby making it possible to provide a highly versatile cushion body 1. Furthermore, when one hem cloth binds two pieces of fabric, it is easier to insert a hand into the opening 4 and pull out the fabrics compared to when one hem cloth binds three or more pieces of fabric.
[0074] In this embodiment, the cushion body 1 has a first sewn portion 8b where the first fabric 11, the second fabric 12, and the first hem cloth 2b are sewn together, a second sewn portion 8c where the third fabric 13, the fourth fabric 14, and the second hem cloth 2c are sewn together, and a third sewn portion 8d where the first hem cloth 2b and the second hem cloth 2c are sewn together. In this case, by providing the first sewn portion 8b, the second sewn portion 8c, and the third sewn portion 8d, the outer edge of the laminated fabric 10 can be firmly sewn.
[0075] In this embodiment, the position of the first rubber part 3 when viewed along the third direction D3 is shifted from the position of the second rubber part 5 when viewed along the third direction D3, and the end of the first rubber part 3 and the end of the second rubber part 5 are aligned along the outer edge of the cushion body 1. Therefore, the first rubber part 3 and the second rubber part 5 can be attached by sewing along the outer edge of the cushion body 1, and therefore sewing the first rubber part 3 and the second rubber part 5 can be easily performed.
[0076] In the manufacturing method of the cushion body according to this embodiment, the first hem cloth 2b binds the outer edge of the first fabric 11 and the outer edge of the second fabric 12, and the second hem cloth 2c binds the outer edge of the third fabric 13 and the outer edge of the fourth fabric 14. Therefore, sewing can be easily performed even if a thick fabric is included among the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14, so that, similarly to the cushion body 1 described above, the types of fabrics used as the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 can be increased.
[0077] The first fabric 11, the second fabric 12, and the first hem cloth 2b are sewn together, the third fabric 13, the fourth fabric 14, and the second hem cloth 2c are sewn together, and further the first hem cloth 2b and the second hem cloth 2c are sewn together. Therefore, the outer edge of the laminated fabric 10 can be firmly sewn. In the manufacturing method of the cushion body 1, an opening 4 is formed between the second fabric 12 and the third fabric 13, through which a hand can be inserted from the outside of the cushion body 1. Then, one hem cloth binds the two fabrics together. Therefore, as in the cushion body 1 described above, the work of inserting a hand into the opening 4 and pulling out the fabric can be easily performed. Furthermore, the opening 4 is formed between the first hem cloth 2b and the second hem cloth 2c. Therefore, since there is no need to cut the fabric, the opening 4 can be easily formed.
[0078] Next, modified examples of the cushion body according to the present disclosure will be described. The configuration of a portion of the cushion body according to the various modified examples described below is the same as the configuration of a portion of the cushion body 1 described above. Therefore, in the following, the same reference numerals will be used to designate the same contents as those of the cushion body 1, and the description will be omitted as appropriate.
[0079] In the above-described embodiment, the laminated fabric 10 has been described in which the third fabric 13 has the highest heat retention index, the fourth fabric 14 has the second highest heat retention index, the second fabric 12 has the third highest heat retention index, and the first fabric 11 has the lowest heat retention index. However, the types of the first fabric, second fabric, third fabric, and fourth fabric constituting the laminated fabric can be changed as appropriate.
[0080] 11(a), the cushion body may have a laminated fabric 20 in which the fourth fabric 24 has the highest heat retention index, the second fabric 22 has the second highest heat retention index, the third fabric 23 has the third highest heat retention index, and the first fabric 21 has the lowest heat retention. For example, the first fabric 21 is a summer fabric, the second fabric 22 and the third fabric 23 are spring / autumn fabrics, and the fourth fabric 24 is a winter fabric.
[0081] As shown in FIG. 11(b), the cushion body may have a laminated fabric 30 in which the second fabric 32 has the highest heat retention index, the third fabric 33 has the second highest heat retention index, the fourth fabric 34 has the third highest heat retention index, and the first fabric 31 has the lowest heat retention index. For example, the first fabric 31 is a summer fabric, the third fabric 33 and the fourth fabric 34 are spring / autumn fabrics, and the second fabric 32 is a winter fabric. In this case, the fourth fabric 34, which has a heat retention index close to that of the first fabric 31, faces the opposite side of the first fabric 31. For example, when the first fabric 31 is applied to the body in summer and the body feels cold, the cushion body can be turned upside down and the fourth fabric 34, which is not too hot, can be applied to the body immediately. Similarly, when the second fabric 32 is applied to the body in winter and the body feels hot, the cushion body can be turned upside down and the third fabric 33, which is not too cold, can be applied to the body immediately.
[0082] As shown in (c) of FIG. 11, the cushion body may have a laminated fabric 40 in which the third fabric 43 has the highest heat retention index, the second fabric 42 has the second highest heat retention index, the fourth fabric 44 has the third highest heat retention index, and the first fabric 41 has the lowest heat retention index. For example, the first fabric 41 is a summer fabric, the second fabric 42 and the fourth fabric 44 are spring / autumn fabrics, and the third fabric 43 is a winter fabric. In this case, the same effect as the laminated fabric 30 is obtained, and the third fabric 43, which has high heat retention, is located at a certain distance from the first fabric 41, which is a summer fabric, so that the heat generated when the first fabric 41 is applied to the body can be more reliably suppressed.
[0083] Fig. 12 is a plan view showing a cushion body 51 according to a modified example. Fig. 13 is a cross-sectional view of the laminated fabric 60 of the cushion body 51 of Fig. 12. As shown in Figs. 12 and 13, the cushion body 51 is a comforter. The cushion body 51 has a laminated fabric 60 and a hem portion 2 that ties together the outer edge of the laminated fabric 60. The hem portion 2 has a first hem cloth 2b and a second hem cloth 2c, similar to the cushion body 1, and the cushion body 51 has an opening 4 which is a portion where the first hem cloth 2b and the second hem cloth 2c are not sewn together.
[0084] The laminated fabric 60 has a first fabric 61, a second fabric 62, a third fabric 63, and a fourth fabric 64. The cushion body 51 has, for example, a straight stitched portion 57 which is a portion where the first fabric 61 and the second fabric 62 are sewn together. The cushion body 51 has a plurality of straight stitched portions 57, and for example, the plurality of straight stitched portions 57 are formed so as to intersect vertically and horizontally. Note that in the cushion body 51, the plurality of straight stitched portions 57 may intersect each other diagonally. Also, the cushion body 51 does not have to have the straight stitched portions 57.
[0085] The cushion body 51 has, for example, a first content 66b accommodated in an internal space formed between the first fabric 61 and the second fabric 62, and a second content 66c accommodated in an internal space formed between the third fabric 63 and the fourth fabric 64. The type of the first content 66b and the type of the second content 66c are, for example, the same as the type of the content 6 described above. However, the type of the first content 66b and the type of the second content 66c may be different from the type of the content 6. In addition, the type of the first content 66b may be the same as or different from the type of the second content 66c.
[0086] As an example, the amount of the second contents 66c is greater than the amount of the first contents 66b. However, the amount of the second contents 66c may be the same as the amount of the first contents 66b, or may be less than the amount of the first contents 66b. At least one of the first contents 66b and the second contents 66c may be made removable from the internal space of the cushion body 51. In this case, the cushion body 51 has an opening / closing member (e.g., a wire fastener) that opens and closes at least one of the internal space formed between the first fabric 61 and the second fabric 62 and the internal space formed between the third fabric 63 and the fourth fabric 64.
[0087] The cushion body 51 has openings 51d at the corners of the cushion body 51 when viewed from the third direction D3. As an example, the openings 51d are formed at the four corners of the cushion body 51 when viewed from the third direction D3. The openings 51d are, like the openings 4, portions where the first hem cloth 2b and the second hem cloth 2c are not sewn together. That is, the openings 51d are formed between the first hem cloth 2b and the second hem cloth 2c. The second fabric 62 and the third fabric 63 located inside the cushion body 51 can be seen from the openings 51d.
[0088] As described above, the cushion body 51 has an opening 4, similar to the cushion body 1. Therefore, the cushion body 51 provides the same effects as the cushion body 1. However, when the first hem cloth 2b and the second hem cloth 2c are joined to each other at the four corners of the cushion body 51, it may be difficult to adjust the shape of the corners of the cushion body 51 when inserting a hand into the opening 4 and pulling out the fabric.
[0089] In contrast, the cushion body 51 has an opening 51d located at a corner of the cushion body 51. Therefore, the second fabric 62 and the third fabric 63 can be pulled out from the opening 4 by inserting a hand into the opening 4 to expose the second fabric 62 and the third fabric 63, and the corner of the cushion body 51 can be easily adjusted. Similarly, the first fabric 61 and the fourth fabric 64 can be pulled out from the opening 4 to expose the first fabric 61 and the fourth fabric 64, and the corner of the cushion body 51 can be easily adjusted. Note that the cushion body 1 described above may have the opening 51d.
[0090] The above describes the embodiment and various modified examples of the cushion body according to the present disclosure. However, the cushion body according to the present disclosure is not limited to the above-mentioned embodiment or modified example, and may be further modified within the scope of the gist described in the claims. That is, the shape, size, material, number and arrangement of each part of the cushion body according to the present disclosure can be appropriately changed within the scope of the gist described above. The cushion body according to the present disclosure may be a cushion body in which a part of the above-mentioned embodiment and the remainder of the modified example are combined, or a cushion body in which a part of the modified example and the remainder of another modified example are combined.
[0091] For example, in the above-mentioned embodiment, an example was described in which the opening 4 is a portion that does not have an opening / closing member. However, the opening may have an opening / closing member. This opening / closing member is, for example, a line fastener, a snap button, or a hook-and-loop fastener. The type of contents contained inside the cushion body can also be changed as appropriate. The contents may be, for example, synthetic cotton or wool-mixed cotton.
[0092] For example, in the above embodiment, the opening 4 is formed along the first side 10b, which is the short side. However, the opening 4 may be formed along the second side 10c, which is the long side. In this case, the opening 4 can be secured widely, which is advantageous in terms of ease of pulling out the fabric. The length of the opening 4 extending along the second side 10c in the second direction D2 is, for example, 90 cm or more and 120 cm or less. The opening 4 extending along the second side 10c is formed, for example, between a pair of first rubber parts 3 arranged along the second direction D2. In this way, the position and number of the openings can be appropriately changed. However, it is more preferable that the number of openings is singular.
[0093] For example, in the above-described embodiment, an example was described in which the first fabric 11, the second fabric 12, the third fabric 13, and the fourth fabric 14 are of different types. However, two or three of the first fabric, the second fabric, the third fabric, and the fourth fabric may be of the same type. Furthermore, the first fabric, the second fabric, the third fabric, and the fourth fabric may be of the same type. The first fabric, the second fabric, the third fabric, and the fourth fabric may be of the same type but may have different thicknesses, hardness, designs, or colors. In this way, the types of the first fabric, the second fabric, the third fabric, and the fourth fabric can be changed as appropriate.
[0094] For example, in the above-mentioned embodiment, the cushion body 1 which is a mattress pad and the cushion body 51 which is a quilt have been described. However, the cushion body according to the present disclosure may be a mattress other than a mattress pad (for example, a mattress), or a quilt other than a quilt (for example, a blanket). The cushion body may be a pillow. Furthermore, the cushion body may be a cushion or a seat cushion. In this way, the present disclosure can be applied to various cushion bodies.
