Description

[Technical field]

[0001] The present disclosure relates to bedding and methods for making bedding. [Background technology]

[0002] Patent Document 1 describes bedding, a method for manufacturing the bedding, and a band. The bedding includes a bedding body that is rectangular in plan view, and a band for attaching the bedding body to a mattress. The bedding body includes a bag body that constitutes the side fabric, and a filling material that is contained inside the bag body. The bag body includes a first quilt and a second quilt that face each other in the thickness direction of the bedding.

[0003] Each of the first quilt and the second quilt has a folded portion where the peripheral portion is folded back to the back side of the other quilt. Therefore, the peripheral portion has a four-layer structure where the two-layer folded portion of the first quilt overlaps with the two-layer folded portion of the second quilt. The inner two layers of the four-layer structure of the peripheral portion are sewn together with a sewing thread that becomes the first seam.

[0004] A non-sewn portion is formed on a portion of the periphery of the bag body, which is not sewn with the sewing thread that will become the first seam. An opening constituted by the non-sewn portion is formed on a portion of the periphery of the bag body. The bag body is turned inside out by pulling out the inner fabric from the opening where the first seam of the bag body is not formed. This operation is performed by pulling out the outer fabric of the first quilt or the outer fabric of the second quilt from the opening.

[0005] A second seam is formed on the inside of the bag body as seen from the first seam. The second seam penetrates the doubled peripheral portion including the folded portion of the first quilt and the doubled peripheral portion including the folded portion of the second quilt. In other words, the second seam penetrates the four-layer structure described above. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2016-87175 A Summary of the Invention [Problem to be solved by the invention]

[0007] Incidentally, bedding is required to keep the body of the user warm while improving breathability to prevent stuffiness, etc. For example, bedding used in summer is desired to have good breathability to alleviate the heat while keeping the body warm from the cold air of the air conditioner.

[0008] An object of the present disclosure is to provide bedding that can enhance both heat retention and breathability. [Means for solving the problem]

[0009] (1) The bedding according to the present disclosure is made of fabric and extends in a first direction and a second direction intersecting the first direction. The bedding includes a body warming section that warms the body of a user of the bedding that comes into contact with the bedding, and a ventilation section that is disposed in a different location from the body warming section and is made of a material that is more breathable than the body warming section.

[0010] This bedding has a body warming section that warms the body of a user of the bedding in contact with the bedding. The user's body can be warmed by contacting the body warming section. The bedding has a ventilation section at a location different from the body warming section, which is made of a material that is more breathable than the body warming section. Therefore, the heat trapped inside the bedding can be released from the ventilation section located at a location different from the body warming section, and the breathability of the bedding can be improved. Therefore, this bedding can improve both heat retention and breathability. Furthermore, by providing the ventilation section at a location different from the body warming section, the user can contact the body warming section when he wants to warm his body, and contact the ventilation section when he is hot. In other words, by being able to select between the body warming section and the ventilation section, the user can select whether to increase heat retention or breathability.

[0011] (2) In the above (1), when the bedding is viewed in a third direction that intersects both the first and second directions, the body warming portion may have a shape that imitates the user's body. In this case, the user's body can be easily placed against the body warming portion, thereby further improving the heat retention effect. Furthermore, heat can be released from the ventilation portion other than the body warming portion that imitates the shape of the body.

[0012] (3) In the above (1) or (2), the ventilation part may be composed of two mesh materials extending in the first direction and the second direction and a honeycomb mesh sandwiched between the two mesh materials. In this case, the ventilation part can be made thinner while improving the breathability. By making the ventilation part out of a thinner material, the bedding can be manufactured more easily.

[0013] (4) In any of the above (1) to (3), the bedding may have a rectangular shape having a long side extending in a first direction and a short side extending in a second direction. The body warming portion may have an upper body contact portion located on one side of the bedding in the first direction and a leg contact portion located on the other side of the bedding in the first direction. Each of the upper body contact portion and the leg contact portion may have a shape that widens as it approaches the short side. In this case, the body warming portion has an upper body contact portion and a leg contact portion, and each of the upper body contact portion and the leg contact portion has a shape that widens as it approaches the end of the bedding in the first direction, which is the longitudinal direction of the bedding. Therefore, the area of ​​the body warming portion widens as it approaches the end of the bedding in the first direction, so that the heat retention of the user's upper body and legs can be further improved.

[0014] (5) In the above (4), the end of the upper body contact portion in the first direction and the end of the leg contact portion in the first direction may coincide with the short side, and the length of the leg contact portion in the first direction may be longer than the length of the upper body contact portion. In this case, the length of the leg contact portion of the body warming portion is longer than the length of the upper body contact portion, so that the user's legs can be more reliably prevented from getting cold.

[0015] (6) The method for manufacturing bedding according to the present disclosure is the method for manufacturing the bedding described above. The bedding may include a front material including a body warming portion and a ventilation portion, a back material having the body warming portion and the ventilation portion, and a core located between the front material and the back material. The method for manufacturing bedding may include the steps of stacking the core, the outer fabric, and the lining in this order so that they are aligned in a third direction that intersects both the first and second directions, sewing together a part of the outer edge of the core, a part of the outer edge of the outer fabric, and a part of the outer edge of the lining as viewed from the third direction, forming openings in the remaining parts of the outer edge of the core, the remaining parts of the outer edge of the outer fabric, and the remaining parts of the outer edge of the lining that are not sewn together in the sewing step, inserting a hand into the opening, pulling the outer fabric out of the opening, and moving the lining to the opposite side of the outer fabric as viewed from the core, thereby turning the outer fabric and the core over and over, and sewing together the remaining parts of the outer edge of the outer fabric, the remaining parts of the outer edge of the core, and the remaining parts of the outer edge of the lining. In this case, by inserting a hand into the opening, which is the unsewn part of the outer edge, to expose the outer fabric, it is possible to eliminate the need to hem the outer edge after exposing it. This eliminates the need to sew a hem, making it easy to manufacture bedding. Furthermore, since there is no need to wrap the hem, the problem of the hem being difficult to dry after washing, etc. can be prevented, making it easier for the bedding to dry.

[0016] (7) In the above (6), in the step of sewing the parts together, a part of the outer edge of the core, a part of the outer edge of the outer fabric, and a part of the outer edge of the lining may be reinforcingly sewn. In this case, when inserting a hand into the opening to expose the outer fabric, the outer edges can be folded back efficiently. This makes it easier to manufacture the bedding. Effect of the Invention

[0017] According to the present disclosure, it is possible to improve both heat retention and breathability. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an embodiment of the bedding and the manufacturing method of the 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 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.

[0020] The bedding according to this embodiment is fabric bedding having a body heat retaining portion that keeps the body of the user of the bedding warm when in contact with the bedding, and a ventilation portion made of a material with higher breathability than the body heat retaining portion. "Bedding" refers to something that is placed on the body when resting. Examples of "bedding" include bedding such as blankets or quilts, bedding such as mattress pads, pillows, cushions, or cushions.

[0021] "User" refers to a person who uses the bedding by placing it against their body. "Body warming section" refers to a part that keeps the user's body warm. The "body warming section" may be a part that protects the user's body from the cold. The "body warming section" may be a part that protects the user's body from the cold air of an air conditioner, for example. "Ventilation section" refers to a part that is more breathable than the body warming section. For example, the body warming section and the ventilation section are made up of multiple pieces of fabric, and the breathability of the multiple pieces of fabric that make up the ventilation section is higher than the breathability of the multiple pieces of fabric that make up the body warming section.

[0022] FIG. 1 is a plan view showing bedding 1 as an example according to this embodiment. The bedding 1 is a comforter. For example, the bedding 1 is made of summer fabric. "Summer fabric" is fabric that is most suitable for use in the summer among the four seasons. In this case, the bedding 1 is a comforter made of thin fabric for summer.

[0023] The bedding 1 extends in a first direction D1 and a second direction D2 intersecting the first direction D1. The first direction D1 is the longitudinal direction of the bedding 1, and the second direction D2 is the transverse direction of the bedding 1. The bedding 1 has a rectangular shape with four corners 1d. The bedding 1 has a long side 1b extending in the first direction D1 and a short side 1c extending in the second direction D2.

[0024] The bedding 1 has a pair of long sides 1b aligned along the second direction D2 and a pair of short sides 1c aligned along the first direction D1. For example, the length of the long sides 1b is 150 cm or more and 250 cm or less (190 cm as an example), and the length of the short sides 1c is 100 cm or more and 200 cm or less (140 cm as an example).

[0025] The bedding 1 has a first surface 1f extending in both the first direction D1 and the second direction D2, and a second surface 1g (see FIG. 3) facing the opposite direction to the first surface 1f. The bedding 1 also has a body warming section 10 that warms the body of the user M in contact with the bedding 1, and a ventilation section 20 that is arranged in a different location from the body warming section 10. The body warming section 10 and the ventilation section 20 are formed on each of the first surface 1f and the second surface 1g. For example, the arrangement of the body warming section 10 and the ventilation section 20 on the first surface 1f is the same as the arrangement of the body warming section 10 and the ventilation section 20 on the second surface 1g.

[0026] When the bedding 1 is viewed (in a plan view) in a third direction D3 that is a direction intersecting the first direction D1 and the second direction D2, the body warming section 10 has a shape that imitates the body of the user M. For example, the body warming section 10 imitates the shape of the body when the user M is lying on his / her back. For example, the arrangement of the body warming section 10 and the ventilation section 20 in a plan view is the same as the arrangement of the body warming section 10 and the ventilation section 20 in a bottom view.

[0027] For example, the body warming section 10 has an upper body contact section 11 located on one side of the first direction D1 of the bedding 1, a leg contact section 12 located on the other side of the first direction D1 of the bedding 1, and a torso contact section 13 located between the upper body contact section 11 and the leg contact section 12. The body warming section 10 has the upper body contact section 11, which can prevent the shoulders of the user M from getting cold. The body warming section 10 has the leg contact section 12, which can prevent the legs of the user M from getting cold. The upper body contact section 11 is a portion that comes into contact with the portion of the user M above the chest, and the leg contact section 12 is a portion that comes into contact with the legs of the user M. The torso contact section 13 is a portion that comes into contact with the portion of the user M from the chest to the buttocks.

[0028] Upper body contact portion 11 has a shape that widens as it approaches short side 1c. An end of upper body contact portion 11 in first direction D1 coincides with short side 1c. For example, upper body contact portion 11 has a trapezoid shape. As one example, upper body contact portion 11 has an isosceles trapezoid shape. Upper body contact portion 11 has upper base portion 11b and lower base portion 11c extending in second direction D2, and a pair of legs 11d connecting the ends of upper base portion 11b and lower base portion 11c to each other.

[0029] The upper base 11b forms a boundary between the upper body contact portion 11 and the torso contact portion 13, and the lower base 11c coincides with the short side 1c. The leg portion 11d extends in a direction inclined toward both the first direction D1 and the second direction D2. The leg portion 11d extends from the end of the upper base 11b to the corner portion 1d of the bedding 1.

[0030] For example, the length of the lower base 11c is two or more and three or less times the length of the upper base 11b. The inclination angle of the leg 11d with respect to the second direction D2 is, for example, 30° or more and 60° or less. The length of the upper body contact portion 11 in the first direction D1 is, for example, 20 cm or more and 60 cm or less (30 cm as an example).

[0031] The leg contact portion 12 has a shape that widens as it approaches the short side 1c. The end of the leg contact portion 12 in the first direction D1 coincides with the short side 1c. The leg contact portion 12 includes two foot contact portions 14. For example, the two foot contact portions 14 are symmetrical with respect to a reference line L that passes through the center of the bedding 1 in a plan view and extends in the first direction D1.

[0032] For example, the foot contact portion 14 has a trapezoidal shape. The foot contact portion 14 has an upper base portion 14b and a lower base portion 14c extending in the second direction D2, and a first leg portion 14d and a second leg portion 14f connecting the ends of the upper base portion 14b and the lower base portion 14c. The upper base portion 14b forms a boundary line between the foot contact portion 12 and the trunk contact portion 13, and the lower base portion 14c coincides with the short side 1c.

[0033] The first leg 14d extends in a direction inclined in both the first direction D1 and the second direction D2. The first leg 14d extends from the end of the upper bottom 14b to the corner 1d of the bedding 1. The second leg 14f extends in a direction inclined in both the first direction D1 and the second direction D2 between the first leg 14d and the reference line L. In the foot contact portion 14, the second leg 14f is inclined to the same side as the first leg 14d with respect to the reference line L. The inclination angle of the second leg 14f with respect to the reference line L is smaller than the inclination angle of the first leg 14d with respect to the reference line L.

[0034] For example, the length of the lower base 14c is 1.5 times or more and 3 times or less than the length of the upper base 14b. The inclination angle of the first leg 14d with respect to the first direction D1 (reference line L) is, for example, 20° or more and 60° or less. The inclination angle of the second leg 14f with respect to the first direction D1 is, for example, 5° or more and 40° or less.

[0035] For example, the length in the first direction D1 of the leg contact portion 12 is longer than the length in the first direction D1 of the upper body contact portion 11. As an example, the length in the first direction D1 of the leg contact portion 12 is 1.5 times or more and 3 times or less than the length in the first direction D1 of the upper body contact portion 11. The length in the first direction D1 of the leg contact portion 12 is, for example, 40 cm or more and 100 cm or less (70 cm as an example). For example, the length of the upper base portion 14b is 15 cm or more and 40 cm or less (26.5 cm as an example), and the length of the lower base portion 14c is 40 cm or more and 70 cm or less (55 cm as an example).

[0036] The trunk contact portion 13 has, for example, a rectangular shape. The trunk contact portion 13 has long sides 13b extending in a first direction D1 and short sides 13c extending in a second direction D2. The trunk contact portion 13 has a pair of long sides 13b aligned along the second direction D2 and a pair of short sides 13c aligned along the first direction D1.

[0037] One of the pair of short sides 13c is a boundary line between the torso contact part 13 and the upper body contact part 11, and the other of the pair of short sides 13c is a boundary line between the torso contact part 13 and the leg contact part 12. For example, the length of the long side 13b is more than 1 time and not more than 3 times the length of the short side 13c. For example, the length of the long side 13b is 50 cm or more and 150 cm or less (90 cm as an example), and the length of the short side 13c is 30 cm or more and 100 cm or less (60 cm as an example).

[0038] The combined shape of the body warming section 10 and the ventilation section 20 in the bedding 1 is rectangular. The ventilation section 20 has, for example, a pair of both side sections 21 located on the end side of the bedding 1 in the second direction D2 as seen from the body warming section 10, and a foot ventilation section 22 located between the pair of foot contact sections 14. The foot ventilation section 22 may be omitted.

[0039] Both side portions 21 have a shape that widens toward the ends of the bedding 1 in the second direction D2. For example, the pair of both side portions 21 are symmetrical with respect to the reference line L. Both side portions 21 have, for example, a trapezoid shape. Both side portions 21 have an upper bottom portion 21b and a lower bottom portion 21f that extend in the first direction D1, and a first leg portion 21c and a second leg portion 21d that connect the ends of the upper bottom portion 21b and the lower bottom portion 21f.

[0040] For example, the upper bottom portion 21b coincides with the long side 13b of the torso contact portion 13, and the lower bottom portion 21f coincides with the long side 1b of the bedding 1. The first leg portion 21c coincides with the leg portion 11d, and the second leg portion 21d coincides with the first leg portion 14d. The length of the side portions 21 in the second direction D2 is, for example, 20 cm or more and 70 cm or less (40 cm as an example).

[0041] The foot ventilation section 22 has a shape that widens toward the end of the bedding 1 in the first direction D1. The foot ventilation section 22 is formed between a pair of foot contact sections 14. For example, the foot ventilation section 22 has a trapezoid shape (as an example, an isosceles trapezoid shape). The foot ventilation section 22 has an upper base 22b and a lower base 22c extending in the second direction D2, and a pair of legs 22d that connect the ends of the upper base 22b and the lower base 22c. For example, the upper base 22b coincides with the short side 13c of the torso contact section 13, and the lower base 22c coincides with the short side 1c of the bedding 1. Each of the pair of legs 22d coincides with the second leg 14f of the foot contact section 14.

[0042] For example, the length in the first direction D1 of the foot ventilation portion 22 is the same as the length in the first direction D1 of the leg contact portion 12 (foot contact portion 14). The length of the lower base portion 22c is, for example, two times or more and ten times or less (4.5 times as an example) the length of the upper base portion 22b. For example, the length of the upper base portion 22b is 1 cm or more and 20 cm or less (7 cm as an example), and the length of the lower base portion 22c is 10 cm or more and 50 cm or less (30 cm as an example).

[0043] By forming the body warming section 10 and the ventilation section 20 as described above, the body of the user M can be in good contact with the body warming section 10 and the ventilation section 20, and the body of the user M can be appropriately warmed while suppressing stuffiness and improving breathability. As shown in FIG. 2, the bedding 1 has a plurality of quilts 30.

[0044] The bedding 1 has the quilt 30, which can prevent twisting of the fabric inside the bedding 1. The quilt 30 is, for example, a straight stitch section where multiple pieces of fabric that make up the bedding 1 are sewn together. The quilt 30 may be a comforter quilt. In this case, the number of stitches in the quilt 30 can be reduced. For example, the quilt 30 includes a peripheral quilt section 31 and an internal quilt section 32 located inside the peripheral quilt section 31 in a plan view.

[0045] For example, the peripheral quilt portion 31 has a rectangular shape on the inside of each of the long side 1b and the short side 1c of the bedding 1 in a plan view. The peripheral quilt portion 31 suppresses twisting of the fabric at the outer edge of the bedding 1. For example, the internal quilt portion 32 includes a first quilt 32b formed in the ventilation portion 20, a second quilt 32c formed in the upper body contact portion 11, a third quilt 32d formed in the torso contact portion 13, and a fourth quilt 32f formed in the leg contact portion 12.

[0046] The internal quilted portion 32 does not have any portion that spans from the body warming portion 10 to the ventilation portion 20. In other words, the entire portion of the internal quilted portion 32 is formed within either the body warming portion 10 or the ventilation portion 20. By forming the internal quilted portion 32 in this manner, it is possible to avoid the possibility that the quilted portion will impair the design of the body warming portion 10 and the ventilation portion 20.

[0047] For example, the inner quilt portion 32 includes a pair of first quilts 32b, each of which is formed on a pair of side portions 21. For example, the first quilt 32b has a curved shape extending in the first direction D1, and is curved so as to protrude inward in a plan view of the bedding 1 as it approaches the center of the first direction D1. The second quilt 32c has a curved shape extending in the second direction D2, and is curved so as to protrude inward in a plan view of the bedding 1 as it approaches the center of the second direction D2.

[0048] The third quilt 32d includes a pair of vertical quilts 32d1 extending in the first direction D1 and a horizontal quilt 32d2 extending in the second direction D2 between the pair of vertical quilts 32d1. For example, the vertical quilt 32d1 is curved and curved so as to protrude inward in a plan view of the bedding 1 as it approaches the center in the first direction D1. The horizontal quilt 32d2 is, for example, linear.

[0049] For example, the fourth quilt 32f includes a pair of linear quilts 32f1 formed in the foot contact portion 14, and a curved quilt 32f2 connecting the ends of the pair of linear quilts 32f1 on the torso contact portion 13 side. The linear quilt 32f1 extends in a direction inclined with respect to both the first direction D1 and the second direction D2 so as to follow the foot contact portion 14. The curved quilt 32f2 is curved and curved so as to protrude inward in a plan view of the bedding 1 as it approaches the center in the second direction D2. As an example, the curved quilt 32f2 is arc-shaped.

[0050] The bedding 1 is made up of three pieces of fabric. Fig. 3 is a cross-sectional view showing the structure of the fabric at the boundary part P between the body warming part 10 and the ventilation part 20 of the bedding 1. As shown in Fig. 3, the boundary part P between the body warming part 10 and the ventilation part 20 is sewn with thread P1. In this embodiment, the body warming part 10 and the ventilation part 20 are each made up of three pieces of fabric. The body warming part 10 is made up of fabric that absorbs moisture (humidity).

[0051] The body warming portion 10 is made of a fabric that is highly absorbent and easy to separate from the skin. Therefore, the body warming portion 10 has excellent sweat absorption and feels dry to the touch. The body warming portion 10 is a portion that protects the body from the cold air of the air conditioner. The ventilation portion 20 is made of a fabric that is more breathable than the body warming portion 10 in order to prevent heat from building up inside the bedding 1.

[0052] For example, the body warming portion 10 is composed of a first outer fabric 16, a core 40, and a second outer fabric 17, which are aligned along the third direction D3. The first outer fabric 16, the core 40, and the second outer fabric 17 extend in both the first direction D1 and the second direction D2, and have a thickness in the third direction D3.

[0053] The first outer fabric 16 is, for example, a fabric made of water-absorbent yarn and water-repellent yarn. For example, the first outer fabric 16 is a knit fabric. The first outer fabric 16 may be made of cool-to-the-touch yarn. The first outer fabric 16 may be a cool-to-the-touch fabric. The first outer fabric 16 may be made of high molecular weight polyethylene, nylon, and polyester.

[0054] For example, the second outer fabric 17 is made of a material different from the first outer fabric 16. In this case, the user M can change the orientation of the bedding 1 in the third direction D3 to bring either the first outer fabric 16 or the second outer fabric 17 into contact with the body, allowing the user M to select the texture according to his / her preference. The second outer fabric 17 is oriented in the opposite direction to the first outer fabric 16. For example, the second outer fabric 17 is a knit waffle fabric. The second outer fabric 17 is made of cotton and polyester. The first outer fabric 16 and the second outer fabric 17 may be made of the same material.

[0055] The first outer fabric 16 of the body warming section 10 and the first outer fabric 26 of the ventilation section 20 constitute the outer fabric 1A including the first surface 1f of the bedding 1, and the second outer fabric 17 of the body warming section 10 and the second outer fabric 27 of the ventilation section 20 constitute the lining 1B including the second surface 1g of the bedding 1. The core 40 is disposed between the outer fabric 1A and the lining 1B. That is, the core 40 is disposed between the first outer fabric 16 and the second outer fabric 17, and between the first outer fabric 26 and the second outer fabric 27.

[0056] For example, the core 40 is a honeycomb mesh. In this case, the core 40 may have a plurality of fine hexagonal holes 40b. Since the core 40 is a honeycomb mesh, the breathability inside the body warming portion 10 is improved. The core 40 may be a double raschel fabric. The thickness of the core 40 (length in the third direction D3) is, for example, thicker than the thickness of the first outer fabric 16 and the thickness of the second outer fabric 17. The thickness of the core 40 may be, for example, 1 cm or more.

[0057] For example, the ventilation section 20 is composed of a first outer fabric 26, a core 40, and a second outer fabric 27 aligned along the third direction D3. The first outer fabric 26 and the second outer fabric 27 extend in both the first direction D1 and the second direction D2 and have a thickness in the third direction D3. The core 40 is shared by the body warming section 10 and the ventilation section 20. The shape of the core 40 when viewed along the third direction D3 is, for example, rectangular, the same as the shape of the bedding 1 when viewed along the third direction D3.

[0058] The first outer fabric 26 and the second outer fabric 27 are made of, for example, a mesh material. In this case, the ventilation section 20 may be made of two mesh materials and a honeycomb mesh sandwiched between the two mesh materials. The first outer fabric 26 and the second outer fabric 27 are made of, for example, the same material. However, the first outer fabric 26 and the second outer fabric 27 may be made of different materials.

[0059] 3 and 4, the first outer fabric 26 has a plurality of holes 26b penetrating in the third direction D3. For example, the plurality of first outer fabrics 26 are arranged in a staggered pattern. For example, the holes 26b have an oval shape. However, the shape of the holes 26b is not limited to an oval shape and can be changed as appropriate.

[0060] For example, the second outer fabric 27 has holes 27b similar to the holes 26b of the first outer fabric 26. The first outer fabric 26, the second outer fabric 27, and the core 40 have holes in the ventilation part 20, thereby improving the breathability of the ventilation part 20. For example, the area of ​​the holes 26b of the first outer fabric 26 and the area of ​​the holes 27b of the second outer fabric 27 are larger than the area of ​​the holes 40b of the core 40. In this case, it is possible to further improve the breathability of the ventilation part 20. However, the relationship between the area of ​​the holes 26b, the area of ​​the holes 27b, and the area of ​​the holes 40b is not limited to the above example. In addition, the ventilation part 20 does not have padding. In this respect, the breathability of the ventilation part 20 is also improved.

[0061] Above, examples of the fabric configurations of the body warming section 10 and the ventilation section 20 have been described. However, the fabric configurations of the body warming section 10 and the ventilation section 20 are not limited to the above examples and can be changed as appropriate. Next, a manufacturing method for the bedding according to this embodiment will be described with reference to Fig. 5. Fig. 5 is a flow chart showing an example of steps in the manufacturing method for the bedding 1.

[0062] First, prepare the outer fabric 1A, the lining 1B, and the core 40 (step of preparing the outer fabric, the lining, and the core). Specifically, prepare the first outer fabric 16 of the body warming part 10 imitating a human shape, and the first outer fabric 26 of the ventilation part 20 consisting of both side parts 21 and the foot ventilation part 22, and sew the first outer fabric 16 and the first outer fabric 26 together to make the rectangular outer fabric 1A.

[0063] Similarly, the second outer fabric 17 of the body warming portion 10 and the second outer fabric 27 of the ventilation portion 20 are prepared, and the second outer fabric 17 and the second outer fabric 27 are sewn together to produce a rectangular lining 1B. Then, a rectangular core 40 extending in both the first direction D1 and the second direction D2 is prepared.

[0064] After preparing the outer fabric 1A, lining 1B, and core 40 as described above, core 40, outer fabric 1A, and lining 1B are layered in this order as shown in Figures 6(a) and 6(b) (step S1: layering core, outer fabric, and lining in this order). At this time, the outer edge of core 40 is aligned with the outer edge of outer fabric 1A and the outer edge of lining 1B, and outer fabric 1A and lining 1B are layered on core 40 to produce a rectangular laminated fabric 1C made of three fabrics.

[0065] Next, a part of the outer edge of the core 40, a part of the outer edge of the outer fabric 1A, and a part of the outer edge of the lining 1B are sewn together (step S2, a process of sewing together parts of the outer edges). At this time, reinforcing stitching may be applied to a part of the outer edge of the core 40, a part of the outer edge of the outer fabric 1A, and a part of the outer edge of the lining 1B. For example, the reinforcing stitching may involve quilting. As an example, the reinforcing stitching may involve multiple quilting operations. Also, the reinforcing stitching may involve overlocking. By applying reinforcing stitching in this manner, the outer edge of the laminated fabric 1C can be reinforced.

[0066] For example, when sewing together a portion of the outer edge of core 40, a portion of the outer edge of outer fabric 1A, and a portion of the outer edge of lining 1B, opening 3 is formed in the remaining portion of the outer edge of core 40, the remaining portion of the outer edge of outer fabric 1A, and the remaining portion of the outer edge of lining 1B (step of forming openings, step S3). For example, opening 3 is formed in a short side of laminated fabric 1C. As one example, opening 3 is formed in the middle of one of the short sides of laminated fabric 1C. Opening 3 may be large enough to allow a hand to be inserted into laminated fabric 1C that has been sewn together to form a bag shape with parts of the outer edges of laminated fabric 1C.

[0067] After the opening 3 is formed, a hand is inserted into the opening 3 to pull the outer fabric 1A out of the opening 3, and the lining fabric 1B is moved to the opposite side of the outer fabric 1A as viewed from the core 40, thereby turning the outer fabric 1A and the core 40 inside out (turning process, step S4). For example, a hand may be inserted into the portion between the outer fabric 1A and the lining fabric 1B in the opening 3 to move the lining fabric 1B to the outside of the core 40 (to the lower side in FIG. 6(b)), thereby exposing the outer fabric 1A and turning the outer fabric 1A and the core 40 inside out.

[0068] Unlike the above example, the core 40, lining 1B, and outer fabric 1A may be layered in this order, the opening 3 may be formed as described above, and then the hand may be inserted into the area between the lining 1B and outer fabric 1A in the opening 3 to move the outer fabric 1A to the outside of the core 40, thereby exposing the lining 1B and reversing the front and back of the outer fabric 1A and the core 40. This results in the laminated fabric 1C with the outer fabric 1A, core 40, and lining 1B lined up in this order.

[0069] After the outer fabric 1A, the core 40, and the lining 1B are arranged in this order in the laminated fabric 1C, the quilt 30 is formed (quilt forming process). For example, a peripheral quilt portion 31 and an internal quilt portion 32 are formed by a sewing machine. Then, the remaining parts of the outer edge of the outer fabric 1A, the remaining parts of the outer edge of the core 40, and the remaining parts of the outer edge of the lining 1B are sewn together (step S5: sewing together the remaining parts of the outer edges). At this time, the opening 3 is closed by sewing, and the bedding 1 is completed, completing a series of steps in the method for manufacturing the bedding 1.

[0070] Next, the effects obtained from the bedding and the manufacturing method of the bedding according to this embodiment will be described. As shown in Fig. 7, the bedding 1 has a body warming part 10 that warms the body of a user M of the bedding 1 who comes into contact with the bedding 1. The body of the user M comes into contact with the body warming part 10, thereby keeping the body of the user M warm.

[0071] The bedding 1 has a ventilation section 20 at a location different from the body warming section 10, which is made of a material with higher breathability than the body warming section 10. Therefore, heat trapped inside the bedding 1 can be released from the ventilation section 20 located at a location different from the body warming section 10, so that the breathability of the bedding 1 can be improved.

[0072] Therefore, it is possible to improve both heat retention and breathability in the bedding 1. Furthermore, by providing the ventilation section 20 at a location different from the body warming section 10, the user M can contact the body warming section 10 when he / she wants to warm up his / her body, and can contact the ventilation section 20 when he / she is hot. In other words, by being able to select between the body warming section 10 and the ventilation section 20, the user M can select whether to improve heat retention or breathability.

[0073] In this embodiment, when the bedding 1 is viewed along the third direction D3, which is a direction intersecting both the first direction D1 and the second direction D2, the body warming section 10 has a shape that imitates the body of the user M. In this case, the body of the user M can be easily pressed against the body warming section 10, so that the heat retention effect can be further improved. Furthermore, heat can be released from the ventilation section 20 other than the body warming section 10 that imitates the shape of the body.

[0074] In this embodiment, as shown in Figures 3 and 7, the ventilation section 20 is made up of two mesh materials (e.g., the first outer fabric 26 and the second outer fabric 27) extending in the first direction D1 and the second direction D2, and a honeycomb mesh (e.g., the core 40) sandwiched between the two mesh materials. In this case, the breathability of the ventilation section 20 is improved and the ventilation section 20 can be made thinner. As the ventilation section 20 is made up of a thinner material, the bedding 1 can be manufactured more easily.

[0075] In this embodiment, the bedding 1 has a rectangular shape having a long side 1b extending in the first direction D1 and a short side 1c extending in the second direction D2. The body warming section 10 has an upper body contact section 11 located on one side of the bedding 1 in the first direction D1 and a leg contact section 12 located on the other side of the bedding 1 in the first direction D1. Each of the upper body contact section 11 and the leg contact section 12 has a shape that widens as it approaches the short side 1c. In this case, the body warming section 10 has the upper body contact section 11 and the leg contact section 12, and each of the upper body contact section 11 and the leg contact section 12 has a shape that widens as it approaches the end of the first direction D1, which is the longitudinal direction of the bedding 1. Therefore, the area of ​​the body warming section 10 widens as it approaches the end of the first direction D1 of the bedding 1, so that the heat retention of the upper body and legs of the user M can be further improved.

[0076] In this embodiment, the end of the upper body contact portion 11 in the first direction D1 and the end of the leg contact portion 12 in the first direction D1 coincide with the short side 1c, and the length of the leg contact portion 12 in the first direction D1 is longer than the length of the upper body contact portion 11 in the first direction D1. In this case, since the length of the leg contact portion 12 of the body warming portion 10 is longer than the length of the upper body contact portion 11, it is possible to more reliably prevent the legs of the user M from getting cold.

[0077] In the method of manufacturing bedding according to this embodiment, by inserting a hand into the opening 3, which is the unsewn portion of the outer edge, to expose the outer fabric 1A, it is possible to eliminate the need to hem the outer edge after exposing it. For example, as shown in Fig. 8(a), the core 40, the outer fabric 1A, and the lining 1B are first stacked in this order, and in the process of inserting the hand into the opening 3 to expose the outer fabric 1A and inserting the core 40, the lining 1B moves to the opposite side of the core 40 from the outer fabric 1A.

[0078] As a result, the outer edge of the lining 1B, the outer edge of the outer fabric 1A, and the outer edge of the core 40 are curved in a U-shape toward the outside of the bedding 1 in a plan view. Therefore, by inserting a hand into the opening 3 and moving the lining 1B to the opposite side to the outer fabric 1A, the outer edge of the bedding 1 is protected without hemming. Therefore, hemming is not necessary for the bedding 1.

[0079] Unlike the above example, when the core 40, lining 1B, and outer fabric 1A are first stacked in this order, and when the hand is inserted into the opening 3 to expose the lining 1B and insert the core 40, the outer fabric 1A moves to the opposite side of the lining 1B as viewed from the core 40. In this case, the outer edge of the outer fabric 1A, the outer edge of the lining 1B, and the outer edge of the core 40 are curved in a U-shape on the outside of the bedding 1 in a plan view. Therefore, as above, hemming can be eliminated.

[0080] In hemming, it is necessary to prepare a strip of fabric different from the fabric constituting the bedding, place the strip of fabric on the outer edge of the bedding, and fold the fabric back to cover the outer edge of the bedding. In bedding with hemming in this way, a fabric different from the fabric constituting the bedding is provided on the outer edge of the bedding, which can cause a problem that the fabric part is difficult to dry after washing, etc.

[0081] That is, in bedding with a hem, the outer edge of the bedding with the hem is difficult to dry. In contrast, bedding 1 does not require hemming, so it has the advantage of being easy to dry after washing. Furthermore, bedding 1 eliminates the need to sew a hem, so the bedding can be easily manufactured.

[0082] In this embodiment, in the step of sewing together the parts, reinforcement stitching may be applied to a part of the outer edge of the core 40, a part of the outer edge of the outer fabric 1A, and a part of the outer edge of the lining fabric 1B. In this case, when inserting a hand into the opening 3 to expose the outer fabric 1A, the outer edges can be efficiently folded back.

[0083] For example, if the core 40 is made of a thick fabric, such as having a thickness of 1 cm or more, the end of the core 40 may protrude from the end of the outer fabric 1A and the inner fabric 1B when the fabric is turned over after normal sewing in the above-mentioned process of sewing together parts. In contrast, if reinforcing stitching is performed in the above-mentioned process of sewing together parts, even if the core 40 is made of a thick fabric, the end of the core 40 will not protrude from the end of the outer fabric 1A and the inner fabric 1B when the fabric is turned over. Therefore, the bedding 1 can be manufactured even more easily.

[0084] The above describes the embodiments of the bedding and the method for manufacturing the bedding according to the present disclosure. However, the bedding and the method for manufacturing the bedding according to the present disclosure are not limited to the contents of the above-mentioned embodiments, and may be further modified within the scope of the gist described in the claims. In other words, the shape, size, material, number and arrangement of each part of the bedding, as well as the contents and order of the steps of the method for manufacturing the bedding, can be appropriately changed within the scope of the above gist.

[0085] For example, as shown in Fig. 8(b), bedding may have multiple cores 40. The example of Fig. 8(b) shows bedding 101 having two cores 40. In this way, even in the case of bedding 101 having multiple cores 40, it is possible to eliminate the need for hemming by carrying out the steps of the manufacturing method according to the embodiment described above. Therefore, the bedding 101 can provide the same effects as the bedding 1 described above.

[0086] For example, in the above-described embodiment, the example of applying reinforcing stitching in the process of sewing together parts has been described. However, reinforcing stitching may not be applied. For example, when the outer fabric 1A, the inner core 40, and the lining fabric 1B are made of thin fabric, reinforcing stitching may not be necessary.

[0087] In the above-mentioned embodiment, the bedding 1 has been described in which the leg contact portion 12 of the body warming portion 10 has a pair of foot contact portions 14, and the foot ventilation portion 22 of the ventilation portion 20 is formed between the pair of foot contact portions 14. However, the bedding may have no foot ventilation portion 22 and the leg contact portion is composed of one foot contact portion. In the above-mentioned embodiment, the body warming portion 10 having a shape imitating the body of the user M, and the bedding 1 having a rectangular shape due to the ventilation portion 20 are exemplified. However, the shapes of the body warming portion, the ventilation portion, and the bedding are not limited to the above example.

[0088] In the above-mentioned embodiment, the bedding 1, which is a comforter made of a thin fabric for summer, has been described. However, the bedding may be a comforter made of a thick fabric for winter or spring and autumn. The bedding may also be a mattress such as a mattress pad or a mattress, or a pillow. Furthermore, the bedding may be a cushion or a seat cushion. In this way, the bedding and the manufacturing method for the bedding according to the present disclosure are applicable to various types of bedding. [Explanation of symbols]
