Description

[Technical Field]

[0001] The present disclosure relates to bedding. [Background technology]

[0002] Patent Document 1 discloses a comforter bedding as a weighted blanket. The comforter bedding has a plurality of compartments along the length and width directions. The comforter bedding has a first zone and a second zone. The first zone has a first set formed by a plurality of compartments. A first pouch is disposed in the first set. The first pouch has a first weight. The first pouch imparts a first weight distribution to the first zone. The second zone has a second set formed by a plurality of compartments. A second pouch is disposed in the second set. The second pouch has a second weight different from the first weight. The second pouch imparts a second weight distribution to the second zone.

[0003] This weighted blanket has multiple compartments, each with an opening through which a pouch containing weighting material such as ceramic beads can be inserted or removed. With this weighted blanket, the pouches can be freely inserted or removed through the multiple openings of the multiple compartments, making it possible to adjust the weight of each part of the weighted blanket.

[0004] [Patent Document 1] US Patent Application Publication No. 2020 / 0170424 Summary of the Invention [Problem to be solved by the invention]

[0005] However, to adjust the weight of the weighted blanket described above, it is necessary to insert pouches into the openings of multiple compartments or reach into the openings to remove pouches from multiple compartments. Because pouches are placed in multiple compartments, it can be difficult to know which compartment a pouch is in. The weighted blanket described above can be inconvenient when attaching and detaching the weighted items, and there is room for improvement in terms of ease of weight adjustment.

[0006] The present disclosure aims to provide a comforter bedding whose weight can be easily adjusted. [Means for solving the problem]

[0007] The comforter according to the present disclosure comprises (1) a plurality of weighted bags containing weighted objects, and a cover covering the weighted bags. The cover has an inner surface to which the weighted bags are detachably fixed.

[0008] In this comforter, the weighted object is contained in a weighted bag. The weighted bag is detachably fixed to the inner surface of the cover. Each of the multiple weighted bags containing the weighted object is detachably attached to the inner surface of the cover. Therefore, by attaching the weighted bag to the inner surface of the cover, the weighted bag can be fixed to the inner surface of the cover, so the comforter can be easily made heavier according to the user's preference. By removing the weighted bag from the inner surface of the cover, the comforter can be easily made lighter according to the user's preference. Since the weight of the comforter is adjusted by attaching and detaching the weighted bag to the inner surface of the cover, it is not necessary to reach into the opening, and the weight of the comforter can be easily adjusted. By looking at the inner surface of the cover, it is easy to see which part of the inner surface of the cover is attached to the weighted bag. Furthermore, if the user of the comforter wants to adjust the weight of the comforter, they can replace the weighted bag with one of the desired weight on the cover. Therefore, the user does not have to touch the weighted object. Therefore, the weight of the comforter can be easily adjusted.

[0009] (2) In the above (1), the weighted bag may have multiple compartments inside. A weighted object may be housed in each of the multiple compartments. In this case, a weighted object is housed in each of the compartments, which are divided parts of the weighted bag. This prevents the weighted object from being distributed unevenly inside the weighted bag, and prevents the weight of the duvet from being unevenly distributed. Therefore, the weighted object can be distributed evenly inside the weighted bag, preventing the weighted object from being concentrated in a specific position during use, thereby reducing the discomfort felt when using the duvet.

[0010] (3) In the above (2), the multiple compartments may be formed by stitching. In this case, the weighted object is housed in each of the multiple compartments separated by stitching. This allows the weighted object to be distributed evenly, further reducing discomfort when using the duvet. Furthermore, when the compartments of the weighted bag are formed by stitching, the compartments can be easily formed by sewing.

[0011] (4) In any of the above (1) to (3), the cover may extend in a first direction and a second direction intersecting the first direction. The weighted bags may be fixed to the inner surface of the cover in a line along the first direction. The weight of the weighted bags fixed to both ends of the cover in the first direction may be heavier than the weight of the weighted bag fixed to the center of the cover in the first direction. In this case, since both ends of the cover in the first direction are heavier than the center of the cover in the first direction, for example, the center of the cover in the first direction, which is located above the body of the user covered by the cover, can be made relatively light. As a result, the cover can be more easily fitted to the body of the user. For example, since the center of the cover in the first direction, which is located above the body of the user covered by the cover, is relatively light, the user can easily turn over in their sleep. Furthermore, since both ends of the cover in the first direction are relatively heavy, the cover can be prevented from shifting relative to the user's body while sleeping, providing the user with a stable sleep.

[0012] (5) In any of the above (1) to (4), the weighted material may be composed of pellets containing polyethylene and polystyrene. When the weighted material is composed of pellets containing polyethylene and polystyrene, the weighted material can be made softer than when the weighted material is glass beads or the like. The softness of the weighted material makes it possible to make the weighted bag less likely to break.

[0013] (6) In the above (5), the weighted material may further contain polyester-containing batting. In this case, for example, the pellets can be covered with polyester batting. This reduces the discomfort felt by the user due to the shape of the pellets. This improves the feel of the duvet and the comfort of the duvet, while also suppressing noise caused by the weighted material moving inside the weighted bag.

[0014] (7) In any of the above (1) to (6), the inner surface of the cover may have a first button. The weighting bag may have a second button to which the first button is attached and detached. The weighting bag and the cover may be detachably fastened to each other by the first button and the second button. In this case, the weighting bag and the cover can be fastened to each other by the first button and the second button, and the weighting bag can be easily removed from the cover. Therefore, the weight of the comforter can be easily adjusted. [Effects of the Invention]

[0015] According to the present disclosure, a comforter bedding whose weight can be easily adjusted can be provided. [Brief explanation of the drawings]

[0017] Hereinafter, an embodiment of a weighted blanket 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 designated by the same reference numerals, and duplicate explanations will be omitted as appropriate. The drawings may be partially simplified or exaggerated to facilitate understanding, and the dimensional proportions and the like are not limited to those shown in the drawings.

[0018] (First embodiment) FIG. 1 is a plan view showing a weighted blanket 1 according to a first embodiment. Weighted blanket 1 is an example of a comforter. Weighted blanket 1 is a comforter made at least in part from a heat-retaining material, and is a comforter with a heat-retaining function that keeps a user A (see FIG. 7) who uses weighted blanket 1 warm. The "user" is a person who uses weighted blanket 1. User A is, for example, a person who places weighted blanket 1 over their body.

[0019] The weighted blanket 1 is, for example, a blanket used to keep warm, but the function of the weighted blanket 1 is not limited to keeping warm. The weighted blanket 1 is, for example, a blanket that is heavier than conventional blankets, and can give the user A a sense of security by providing a moderate weight to the user A, thereby inducing the user A to fall asleep comfortably. As an example, the weighted blanket 1 is used by a user A who has trouble falling asleep or who suffers from anxiety. When such a user A uses the weighted blanket 1, the anxiety felt by the user A can be alleviated, and the user A can fall asleep more easily.

[0020] The weight of the weighted blanket 1 is adjustable. The weight of the weighted blanket 1 is adjusted, for example, by the user A. However, the weight of the weighted blanket 1 may also be adjusted by someone other than the user A, for example, by the seller of the weighted blanket 1. The weight of the weighted blanket 1 is adjusted, for example, to be greater than or equal to 1 kg and less than or equal to 15 kg. The weight of the weighted blanket 1 is adjusted, for example, to be greater than or equal to 5% and less than or equal to 15% (10%, for example) of the body weight of the user A. The weighted blanket 1 is also referred to as a weighted blanket or a gravity blanket. The weighted blanket 1 has a plurality of weighted bags 20 containing weighted objects 24 (see FIG. 6 ) and a cover 10 that covers the plurality of weighted bags 20.

[0021] In the following description, the longitudinal direction of the weighted blanket 1 when in use will be referred to as the longitudinal direction D1 (first direction), the width direction of the weighted blanket 1 when in use as the width direction D2 (second direction), and the thickness direction of the weighted blanket 1 when in use as the thickness direction D3. However, these directions are for convenience of explanation and do not limit the position or direction of objects. For example, if the weighted blanket 1 extends along a horizontal plane, the longitudinal direction D1 and width direction D2 are horizontal directions, and the thickness direction D3 is vertical. For example, the longitudinal direction D1, width direction D2, and thickness direction D3 are perpendicular to one another.

[0022] The outer fabric 10 may be made of, for example, a heat-retaining material. A "heat-retaining material" is a material that insulates the body heat of the user A of the weighted blanket 1 from escaping outside the weighted blanket 1. The outer fabric 10 may be made of, for example, broadcloth, satin, blanket, or brushed fabric. The outer fabric 10 may be made of, for example, a woven or knitted fabric made of cotton, wool, silk, animal hair, acrylic, nylon, polyester, or the like. The outer fabric 10 may be made of, for example, a microfiber containing polyester. The animal hair may be, for example, cashmere, mohair, alpaca, camel, or angora.

[0023] The side fabric 10 extends in a longitudinal direction D1 and a width direction D2 intersecting the longitudinal direction D1. The side fabric 10 has a rectangular shape in which the length in the longitudinal direction D1 is longer than the length in the width direction D2. In this disclosure, "rectangular" includes not only strict rectangles but also shapes that look like rectangles, such as rectangles with rounded corners or rectangles with notched corners, that are not strictly rectangular. Furthermore, "rectangular" also includes squares with four sides of equal length.

[0024] FIG. 2 is a plan view showing the side fabric 10 of the weighted blanket 1 according to the first embodiment. FIG. 1 shows the side fabric 10 in a closed state, and FIG. 2 shows the side fabric 10 in an open state. As shown in FIGS. 1 and 2, the side fabric 10 can be opened and closed. The side fabric 10 has a first side 10a, a second side 10b, and a third side 10c.

[0025] The second side 10b extends in the longitudinal direction D1. When the side fabric 10 is open, the side fabric 10 has a pair of second sides 10b. The first side 10a and the third side 10c each extend in the width direction D2. The first side 10a and the third side 10c each are aligned along the longitudinal direction D1. When the side fabric 10 is open, the length of each of the first side 10a and the third side 10c is longer than the length of the second side 10b. The first side 10a, the second side 10b, and the third side 10c form the outer periphery of the side fabric 10 in the open state.

[0026] The side fabric 10 has a central imaginary line 11. The central imaginary line 11 is a folding line for folding the side fabric 10 in an open state. The central imaginary line 11 extends along the longitudinal direction D1 and is located at the center of the side fabric 10 in the width direction D2 in an open state. User A folds the side fabric 10 in half along the central imaginary line 11 and uses the weighted blanket 1 with the side fabric 10 in a closed state. The side fabric 10 is folded in half along the central imaginary line 11 to cover the weighted bag 20, which will be described in detail later.

[0027] As described above, the central imaginary line 11 extends along the longitudinal direction D1 at the center in the width direction D2 of the opened side fabric 10. However, instead of the central imaginary line 11, the side fabric 10 may have a fold line extending along the longitudinal direction D1 at a position shifted from the center in the width direction D2 of the opened side fabric 10.

[0028] When the weighted blanket 1 is in use (when the side fabric 10 is folded in half along the central imaginary line 11), the side fabric 10 has a rectangular shape in which the length in the width direction D2 is shorter than the length in the longitudinal direction D1 (see FIG. 1). "In use" refers to when a user A uses the weighted blanket 1. When in use, the side fabric 10 is in a closed state. For example, when in use, the length of the first side 10a is equal to the length of the third side 10c, and the length of the second side 10b is equal to the length of the central imaginary line 11. When in use, the lengths of the first side 10a and the third side 10c are shorter than the lengths of the second side 10b and the central imaginary line 11, respectively. When in use, the lengths of the first side 10a and the third side 10c are, for example, 80 cm or more and 120 cm or less. The lengths of the second side 10b and the central imaginary line 11 are, for example, 120 cm or more and 160 cm or less. When in use, the outer periphery of the side fabric 10 is formed by the first side 10a, the second side 10b, the third side 10c and the central imaginary line 11.

[0029] Weighted blanket 1 is, for example, a half blanket. A "half blanket" is a blanket that does not cover user A's entire body, but rather covers, for example, only the upper half of user A's body (see Figure 7). Weighted blanket 1 may also be a half blanket that covers user A's chest and abdomen. In this case, the feeling of restraint felt by user A's feet when user A puts weighted blanket 1 over them can be reduced. Weighted blanket 1, which is a half blanket, mainly covers user A's upper body. This makes the half blanket less likely to slip off of user A, making it easier for user A to feel secure.

[0030] The side fabric 10 has a zipper 12. The zipper 12 has a pair of elements 13 that are aligned along the thickness direction D3 when the side fabric 10 is closed, a slider 14 that opens and closes the pair of elements 13, and a tape portion for fixing the elements 13 to the side fabric 10. The tape portion is sewn to the first side 10a, the second side 10b, and the third side 10c so as to fit along the outer periphery of the side fabric 10 in the open state. The elements 13 are fixed to the first side 10a, the second side 10b, and the third side 10c via the tape portion so as to fit along the outer periphery of the open side fabric 10.

[0031] When the side fabric 10 is folded in half, the slider 14 moves and the pair of elements 13 close, thereby closing the side fabric 10. For example, when the weighted blanket 1 is viewed along the thickness direction D3 with the side fabric 10 closed, the pair of elements 13 are U-shaped. In this case, the fastener 12 is a U-shaped fastener.

[0032] The fastener 12 is, for example, a concealed fastener having a covering portion that covers the pair of elements 13 closed by the slider 14. The fastener 12 is a fastener that uses the covering portion to cover and conceal the elements 13 so that they cannot be seen from the outside. When the fastener 12 is a concealed fastener, it is possible to reduce the risk of the slider 14 getting caught when moved. Furthermore, because the elements 13 are not exposed, it is possible to prevent the elements 13 from coming into contact with the user's body and causing discomfort to the user.

[0033] The side fabric 10 has an inner surface 15 to which a weighted bag 20 (described later) is detachably fixed. The inner surface 15 is the surface of the side fabric 10 that faces inward when the side fabric 10 is folded in half at the central imaginary line 11. The inner surface 15 is the surface that faces the weighted bag 20 (see Figure 4).

[0034] Figure 3 is a plan view showing the side fabric 10 of the weighted blanket 1 according to the first embodiment. Figure 3 shows half of the inner surface 15 of the side fabric 10. As shown in Figure 3, the inner surface 15 of the side fabric 10 has a weight bag placement area 17 where a weight bag 20 (described later) is placed, and a portion of the inner surface 15 (e.g., half of the inner surface 15) is designated as the weight bag placement area 17. The inner surface 15 has multiple weight bag placement areas 17.

[0035] The inner surface 15 of the side fabric 10 has a first button 16. The first button 16 is fixed to the weight bag placement area 17. The first button 16 is, for example, a female snap button. The first button 16 has, for example, an engaging portion to which a second button 21 (see FIG. 5) of the weight bag 20, which will be described later, is engaged. On the inner surface 15, the engaging portion of the first button 16 faces vertically upward.

[0036] The first button 16 is fixed, for example, by sewing to the inner surface 15. A plurality of first buttons 16 are arranged on the inner surface 15. The plurality of first buttons 16 are arranged along the longitudinal direction D1. For example, a plurality of groups each consisting of a plurality of first buttons 16 arranged along the longitudinal direction D1 are arranged along the width direction D2. For example, the arrangement intervals of the plurality of first buttons 16 arranged along the longitudinal direction D1 are different from each other. As an example, the distance from the first button 16 located nth (n is a natural number) from the end of the inner surface 15 in the longitudinal direction D1 to the first button 16 located n+1th from the end of the inner surface 15 in the longitudinal direction D1 is different from the distance from the first button 16 located n+1th from the end of the inner surface 15 in the longitudinal direction D1 to the first button 16 located n+2th from the end of the inner surface 15 in the longitudinal direction D1.

[0037] For example, the arrangement intervals of the multiple first buttons 16 lined up along the width direction D2 are different from one another. As an example, the distance from the first button 16 located nth from the end of the inner surface 15 in the width direction D2 to the first button 16 located n+1th from the end of the inner surface 15 in the width direction D2 is different from the distance from the first button 16 located n+1th from the end of the inner surface 15 in the width direction D2 to the first button 16 located n+2th from the end of the inner surface 15 in the width direction D2.

[0038] In this embodiment, the inner surface 15 has a polygonal area formed by a plurality of first buttons 16. As an example, the polygonal area is square. A first button 16 is arranged at each of the four corners of the square area. For example, six sets of four first buttons 16 are arranged on the inner surface 15. In this case, 24 first buttons 16 are arranged on the inner surface 15.

[0039] For example, a weight bag arrangement area 17 is formed on the inner surface 15 by a set of a plurality of first buttons 16 (four, for example). The weight bag arrangement area 17 is an area having a polygonal shape (a square, for example) with the first buttons 16 as corners. In this embodiment, six weight bag arrangement areas 17 are formed. More specifically, three weight bag arrangement areas 17 are formed along the longitudinal direction D1, and two weight bag arrangement areas 17 are formed along the width direction D2. The multiple weight bag arrangement areas 17 are arranged adjacent to each other on the inner surface 15. For example, a gap is formed between two weight bag arrangement areas 17 aligned along the longitudinal direction D1, and a gap is formed between two weight bag arrangement areas 17 aligned along the width direction D2.

[0040] FIG. 4 is a perspective view showing the side fabric 10 of the weighted blanket 1 in an open state. Multiple weight bags 20 are secured to the inner surface 15 of the side fabric 10, aligned along the longitudinal direction D1. For example, multiple weight bags 20 are secured to the inner surface 15 of the side fabric 10, aligned along the width direction D2. FIG. 5 is a plan view showing weight bags 20 arranged on the inner surface 15 of the side fabric 10. The weight bags 20 are detachably attached to the weight bag placement area 17 described above. Specifically, three weight bags 20 aligned along the longitudinal direction D1 and two weight bags 20 aligned along the width direction D2 can be arranged on the inner surface 15. However, the number of weight bags 20 aligned along the longitudinal direction D1 and the width direction D2 can be changed by attaching and detaching weight bags 20 to and from the weight bag placement area 17. As an example, six weight bags 20 are arranged on the inner surface 15 of the side fabric 10.

[0041] The weighted bags 20 are fixed to the weighted bag placement areas 17 on the inner surface 15. The weighted bags 20 can be attached and detached to each of the weighted bag placement areas 17. The weight of the weighted blanket 1 can be adjusted by attaching and detaching the weighted bags 20 to and from the inner surface 15 of the side fabric 10. Specifically, in the weighted blanket 1, weighted bags 20 of different weights can be placed in each of the multiple weighted bag placement areas 17. The weighted blanket 1 may have multiple types of weighted bags 20 with different weights. Multiple types of weighted bags 20 with different weights may be placed in each of the multiple weighted bag placement areas 17. Therefore, user A can partially adjust the weight of the weighted blanket 1 by attaching and detaching the weighted bags 20.

[0042] Furthermore, the weighted bag 20 can be removed from the side fabric 10. This allows the side fabric 10 to be easily washed, enabling the weighted blanket 1 to be used hygienically. Furthermore, by looking at the inner surface 15 of the side fabric 10, the user A can easily determine to which of the multiple weighted bag placement areas 17 the weighted bag 20 is attached.

[0043] FIG. 6 is an enlarged plan view showing the weight bag 20. The weight bag 20 has, for example, a rectangular shape. In this embodiment, the weight bag 20 has a square shape with four sides of equal length. The weight bag 20 has a pair of horizontal sides 20a extending along the longitudinal direction D1 and a pair of vertical sides 20b extending along the width direction D2. The horizontal sides 20a and the vertical sides 20b have, for example, the same length. The horizontal sides 20a and the vertical sides 20b have, for example, a length of 40 cm or more and 50 cm or less. The horizontal sides 20a and the vertical sides 20b form the outer periphery of the weight bag 20. The weight bag 20 is made of, for example, a blended fiber containing polyester and polyurethane.

[0044] The weight bag 20 has a second button 21 that is attached to and detached from the first button 16. The weight bag 20 has a plurality of second buttons 21. For example, the second buttons 21 are fixed to the weight bag 20 by sewing. For example, a second button 21 is fixed to each of the four corners of the weight bag 20. In this embodiment, the weight bag 20 has four second buttons 21. The second buttons 21 may be fixed so as to penetrate the weight bag 20 in the thickness direction D3.

[0045] The second button 21 is, for example, a male snap button. In this case, the second button 21 is aligned in the thickness direction D3 with the first button 16 fixed to the inner surface 15 of the side fabric 10, and is joined to the first button 16 when pressed by the first button 16. The second button 21 fixed to the weighted bag 20 has a locking portion on one side of the weighted blanket 1 in the thickness direction D3. This locking portion locks into the locked portion of the first button 16, thereby joining the second button 21 to the first button 16.

[0046] Each of the second buttons 21 is attached to the weight bag 20 with its locking portion facing the first button 16 of the side fabric 10. The locking portions of the second buttons 21 face the same side in the thickness direction D3. For example, the locking portions of the second buttons 21 face vertically downward.

[0047] As described above, the weight bag 20 is placed in the weight bag placement area 17 on the inner surface 15. At this time, the fastening portions of the second buttons 21 placed at each corner (for example, the four corners) of the weight bag 20 are fastened to the fastening portions of a plurality of (for example, four) first buttons 16 placed on the inner surface 15 of the side fabric 10. This allows the weight bag 20 to be fixed to the inner surface 15 of the side fabric 10, and also allows the weight bag 20 to be removed from the inner surface 15 of the side fabric 10. Therefore, the weight bag 20 and the side fabric 10 are detachably fixed to each other by the first buttons 16 and the second buttons 21.

[0048] The weighted bag 20 has a display unit (not shown) that displays the weight of the weighted bag 20. The display unit is, for example, a tag or label such as a PISNAME (Peace Name). By looking at the display unit, the user A can easily determine the weight of the weighted bag 20.

[0049] The weight bag 20 has multiple compartments 22 inside. The compartments 22 are portions in which weighted objects 24, which will be described in detail later, are housed. The multiple compartments 22 are formed by stitches 23. The stitches 23 are seams provided on the front surface 20c and the back surface 20d of the weight bag 20. The front surface 20c and the back surface 20d face in opposite directions. The front surface 20c and the back surface 20d are aligned along the thickness direction D3.

[0050] The partitions 22 and the stitches 23 will be described in detail below. The stitches 23 have horizontal stitches 23a extending in the longitudinal direction D1 and vertical stitches 23b extending in the width direction D2. For example, one horizontal stitch 23a and one vertical stitch 23b are provided on each of the front surface 20c and the back surface 20d of the weight bag 20. For example, the horizontal stitches 23a and the vertical stitches 23b are formed on the front surface 20c and the back surface 20d of the weight bag 20 so as to form a cross shape.

[0051] The partitions 22 are defined by horizontal stitches 23a and vertical stitches 23b. A plurality of (for example, four) partitions 22 are formed in the weighted bag 20. Each of the plurality of partitions 22 is defined by horizontal stitches 23a and vertical stitches 23b and the horizontal sides 20a and vertical sides 20b of the weighted bag 20. The internal space of the weighted bag 20 is divided into a plurality of (for example, four) partitions 22. For example, one second button 21 is disposed in one partition 22. In this embodiment, cross-shaped stitches 23 are formed in the square-shaped weighted bag 20. Therefore, the weighted bag 20 can be rotated 90 degrees when used in the weighted blanket 1.

[0052] A weighted object 24 is housed in each of the multiple compartments 22. A "weighted object" is a member that provides a sense of weight to user A. The weighted object 24 is interposed between the front surface 20c and the back surface 20d of the weighted bag 20 in the compartments 22. For example, the front surface 20c, the weighted object 24, and the back surface 20d are arranged in this order in the thickness direction D3 of the weighted bag 20. In this case, the weighted bag 20 has a three-layer structure of the front surface 20c, the weighted object 24, and the back surface 20d. The weighted bag 20 is quilted by stitches 23 sewn to the front surface 20c and the back surface 20d. The quilt may be formed by sewn quilting.

[0053] For example, the weight of the weighted object 24 to be accommodated in the weighted bag 20 is adjusted when the weighted bag 20 is manufactured. As described above, for example, multiple types of weighted bags 20 may be prepared, and the weights of the multiple types of weighted bags 20 may be different from one another. For example, a first weighted bag 20 and a second weighted bag 20 heavier than the first weighted bag 20 may be prepared, and the first weighted bag 20 and the second weighted bag 20 may be selectable as the weighted bag 20 to be fixed to the inner surface 15. In this way, two types of weighted bags 20 with different weights may be selectable, or three or more types of weighted bags 20 with different weights may be selectable.

[0054] The weight of the weighted bag 20 is determined by the weight of the weighted object 24 housed inside the weighted bag 20. As an example, the weighted object 24 housed in the weighted bag 20 comes in three weights: 300 g, 500 g, and 700 g. By attaching the weighted bags 20 housing these weighted objects 24 to any of the weighted bag placement areas 17 on the inner surface 15, it is possible to form heavy weight areas and light weight areas in the weighted blanket 1. Note that the weights of the weighted objects 24 listed above are just examples, and the weights of the weighted objects 24 are not limited to these weights. The same applies to the following description.

[0055] For example, the weight 24 is made of pellets 24a containing polyethylene and polystyrene. The pellets 24a may be pellets of foam beads before they are expanded. The diameter of the pellets 24a is, for example, 1 mm or more and 10 mm or less. Note that the weight 24 does not have to be made of pellets 24a, and the type of the weight 24 is not particularly limited. For example, the weight 24 may be made of adzuki beans.

[0056] For example, the weighted object 24 further includes a padding 24b containing polyester. The weighted object 24 may be composed of pellets 24a and padding 24b. A void is formed inside the padding 24b. The pellets 24a may be disposed in the void formed inside the padding 24b. The weighted object 24 may have a pair of paddings 24b aligned along the thickness direction D3. The pellets 24a may be disposed between the pair of paddings 24b aligned along the thickness direction D3. The padding 24b may be torn by hand to form the pair of paddings 24b aligned along the thickness direction D3 as described above.

[0057] For example, the pellets 24a may be contained in a bag and stored inside the weighted bag 20. This bag is a bag for storing the pellets 24a. For example, the bag storing the pellets 24a may be placed in a void formed inside the padding 24b. The weighted object 24 may have a layered structure consisting of a bag storing the pellets 24a and padding 24b, arranged along the thickness direction D3. The pellets 24a and padding 24b may be mixed together inside the weighted bag 20. By mixing the pellets 24a and padding 24b together, the pellets 24a can be made less likely to move in the partition section 22. This makes it possible to prevent the pellets 24a from being unevenly distributed in the partition section 22.

[0058] Next, an example of a manufacturing method for the weighted bag 20 will be described. For example, pellets 24a and batting 24b are prepared as the weighted objects 24 to be contained in the weighted bag 20 so as to have the weights exemplified above. Next, to form the weighted bag 20, multiple (two) pieces of fabric are sewn together into a bag shape. This forms a bag that will later become the weighted bag 20. Then, stitches 23 are provided in the sewn bag to form compartments 22. At this time, for each compartment 22, a slit is made in the vertical side 20b or horizontal side 20a that defines each compartment 22 to accommodate the weighted objects 24. Then, the weighted objects 24 are inserted into the compartments 22 through the slit. After the weighted objects 24 are inserted, the slits are sewn together to complete the weighted bag 20. Note that before or after sewing together the slits, the outer periphery of the weighted bag 20 may be sandwiched with a hem and sewn together with the hem. In this case, the outer periphery of the weighted bag 20 can be strengthened. Through the above steps, the series of steps in the method for manufacturing the weighted bag 20 is completed.

[0059] 7 is a plan view showing an example of how the weighted blanket 1 according to the first embodiment is used. For example, multiple weighted bags 20 are fixed to the inner surface 15 of the side fabric 10 so that the weight of the weighted bags 20 fixed to both end portions 201 of the side fabric 10 in the longitudinal direction D1 is heavier than the weight of the weighted bag 20 fixed to the center portion 202 of the side fabric 10 in the longitudinal direction D1.

[0060] In this embodiment, the weighted bag 20 containing a 300 g weighted object 24 is arranged in the center portion 202. The weighted bags 20 containing a 500 g weighted object 24 and a 700 g weighted object 24 are arranged at both end portions 201. The weighted object 24 located on one side of both end portions 201 in the width direction D2 is lighter than the weighted object 24 located on the other side of both end portions 201 in the width direction D2. In this embodiment, one side of both end portions 201 in the width direction D2 is the foot side of user A. The other side of both end portions 201 in the width direction D2 is the head side of user A. The weighted bag 20 containing a 500 g weighted object 24 is arranged on one side (foot side) of both end portions 201 in the width direction D2. The weighted bag 20 containing a 700 g weighted object 24 is arranged on the other side (head side) of both end portions 201 in the width direction D2.

[0061] As described above, in weighted blanket 1, both end portions 201 are heavier than central portion 202, and central portion 202 is lighter than both end portions 201, so weighted blanket 1 can easily surround and cover the body of user A. As a result, weighted blanket 1 can easily conform to the body of user A.

[0062] The heavy weighted bags 20 (500 g, 700 g) located at both ends 201 make it difficult for the weighted blanket 1 to move in both the longitudinal direction D1 and the width direction D2. This prevents the weighted blanket 1 from shifting relative to the user A's body while the user A is sleeping, providing the user A with a stable sleep. In the above example, the weighted bag 20 containing the 700 g weighted object 24 is positioned on the head side of the user A, and the weighted bag 20 containing the 500 g weighted object 24 is positioned on the foot side of the user A. Therefore, the load of the weighted bag 20 on the foot side of the user A is smaller than the load of the weighted bag 20 on the head side of the user A, so the user A's feet are less likely to be restricted. As a result, the user A can easily turn over in his sleep.

[0063] The lightweight weighted bag 20 (300 g) located in the center portion 202 does not apply excessive pressure to the user A, making it easier for the user A to turn over in bed. Furthermore, pressure on the organs of the user A by the weighted blanket 1 can be reduced.

[0064] A frilled tongue may be attached to each of the first side 10a and the third side 10c of the weighted blanket 1. "Frill" refers to a wavy shape, such as pleats. "Tongue" refers to a part used to secure the weighted blanket 1 to other bedding. The tongue is secured to the bedding, such as a futon or mattress, on which the user A rests. This configuration allows the weighted blanket 1 to be used by wrapping it around the bottom of the bedding. This prevents the weighted blanket 1 from falling off the bedding.

[0065] Next, the effects and advantages obtained from the weighted blanket 1 according to this embodiment will be described in more detail. In this weighted blanket 1, the weighted object 24 is housed in a weighted bag 20. As shown in FIG. 4, the weighted bag 20 is removably fixed to the inner surface 15 of the side fabric 10. Each of the multiple weighted bags 20 housing the weighted object 24 is removably attached to the inner surface 15 of the side fabric 10. Therefore, by attaching the weighted bag 20 to the inner surface 15 of the side fabric 10, the weighted bag 20 can be fixed to the inner surface 15 of the side fabric 10, allowing the weight of the weighted blanket 1 to be easily adjusted according to the user A's preferences. By removing the weighted bag 20 from the inner surface 15 of the side fabric 10, the weight of the weighted blanket 1 can be easily adjusted according to the user A's preferences. Since the weight of the weighted blanket 1 can be adjusted by attaching or detaching the weighted bag 20 to the inner surface 15 of the side fabric 10, it is not necessary to reach into the opening, and the weight of the weighted blanket 1 can be easily adjusted. By looking at the inner surface 15 of the side fabric 10, it is easy to see which part of the inner surface 15 of the side fabric 10 the weighted bag 20 is attached to. Furthermore, if user A of the weighted blanket 1 wants to adjust the weight of the weighted blanket 1, he or she can replace the weighted bag 20 with one having the desired weight relative to the side fabric 10. Therefore, user A does not need to touch the weighted object 24. Therefore, the weight of the weighted blanket 1 can be easily adjusted.

[0066] The weighted bag 20 also has a plurality of compartments 22 inside. A weighted object 24 is housed in each of the plurality of compartments 22. A weighted object 24 is housed in each of the compartments 22, which are partitioned portions of the weighted bag 20. This prevents the weighted objects 24 from being distributed unevenly inside the weighted bag 20, and prevents the weight of the weighted blanket 1 from being biased. Therefore, the weighted objects 24 can be distributed evenly inside the weighted bag 20, preventing the weighted objects 24 from being biased to a specific position during use, thereby reducing any discomfort felt when using the weighted blanket 1.

[0067] Furthermore, since the multiple compartments 22 are formed by stitches 23, the weighted objects 24 are contained in each of the multiple compartments 22 separated by the stitches 23. This allows the weighted objects 24 to be distributed evenly, further reducing any discomfort felt when using the weighted blanket 1. Furthermore, when the compartments 22 of the weighted bag 20 are formed by stitches 23, the compartments 22 can be easily formed by sewing.

[0068] The side fabric 10 extends in the longitudinal direction D1 and in a width direction D2 that intersects with the longitudinal direction D1. Multiple weighted bags 20 are secured to the inner surface 15 of the side fabric 10, aligned along the longitudinal direction D1. The weights of the weighted bags 20 secured to both end portions 201 of the side fabric 10 in the longitudinal direction D1 are heavier than the weights of the weighted bags 20 secured to the center portion 202 of the side fabric 10 in the longitudinal direction D1. Because the both end portions 201 of the weighted blanket 1 in the longitudinal direction D1 are heavier than the center portion 202 of the weighted blanket 1 in the longitudinal direction D1, the center portion 202 of the weighted blanket 1 in the longitudinal direction D1, which is located above the body of the user A covered by the weighted blanket 1, can be made relatively light. As a result, the weighted blanket 1 can be more easily fitted to the body of the user A. Additionally, the center portion 202 of the weighted blanket 1 in the longitudinal direction D1, which is located above the body of the user A covered by the weighted blanket 1, is relatively light, making it easier for the user A to turn over in his sleep. Furthermore, the weighted blanket 1 is prevented from shifting relative to the body of the user A while the user A is sleeping, as both end portions 201 of the weighted blanket 1 in the longitudinal direction D1 are relatively heavy, thereby providing the user A with a stable sleep.

[0069] Furthermore, the weighted object 24 is made of pellets 24a containing polyethylene and polystyrene. When the weighted object 24 is made of pellets 24a containing polyethylene and polystyrene, the weighted object 24 can be made softer than when the weighted object 24 is made of glass beads or the like. The softness of the weighted object 24 makes it possible to make the weighted bag 20 less likely to break.

[0070] The weighted object 24 further includes batting 24b containing polyester. In this embodiment, for example, the pellets 24a can be covered with the polyester batting 24b. This reduces the discomfort felt by the user A due to the shape of the pellets 24a. This improves the feel of the weighted blanket 1 against the skin, and also reduces noise caused by the weighted object 24 moving inside the weighted bag 20, improving the comfort of the weighted blanket 1.

[0071] Additionally, the inner surface 15 of the side fabric 10 has a first button 16. The weighted bag 20 has a second button 21 to which the first button 16 is attached and detached. The first button 16 and the second button 21 removably fasten the weighted bag 20 and the side fabric 10 to each other. This allows the weighted bag 20 and the side fabric 10 to be fastened to each other by the first button 16 and the second button 21, and also allows the weighted bag 20 to be easily removed from the side fabric 10. Therefore, the weight of the weighted blanket 1 can be easily adjusted.

[0072] (Second embodiment) FIG. 8 is a plan view showing a weighted blanket 2 according to the second embodiment, along with an example of its use. The weighted blanket 2 has a weighted bag 20A, which is different from the weighted bag 20 with the cross stitches 23 formed therein. For example, the weighted bags of the weighted blanket 2 do not include the weighted bag 20, but are all weighted bags 20A. The rest of the configuration of the weighted blanket 2 is the same as that of the weighted blanket 1. Therefore, redundant explanations will be omitted below.

[0073] The weight bag 20A does not have vertical stitches 23b, but only horizontal stitches 23a. That is, only horizontal stitches 23a are provided on the front surface 20c and the back surface 20d of the weight bag 20A. A plurality of horizontal stitches 23a are formed on the front surface 20c and the back surface 20d of the weight bag 20A. The plurality of horizontal stitches 23a are formed in a striped pattern. In this embodiment, the weight bag 20A has three horizontal stitches 23a.

[0074] The horizontal stitches 23a form partitions 22A. The weighted bag 20A has multiple (four, for example) partitions 22A formed by multiple (three, for example) horizontal stitches 23a. The internal space of the weighted bag 20A is divided into multiple (four, for example) partitions 22A. The partitions 22A are arranged side by side along the width direction D2. The length of the partitions 22A in the longitudinal direction D1 is longer than the length of the partitions 22A in the width direction D2. This causes the weighted object 24 accommodated in the partitions 22A to expand along the longitudinal direction D1. The weighted object 24 accommodated in the partitions 22A is more restricted in movement in the width direction D2 than in movement in the longitudinal direction D1. The other configurations of the weighted bag 20A are the same as those of the weighted bag 20.

[0075] As described above, in the weighted blanket 2 according to the second embodiment, the weighted object 24 contained in the compartment 22A is restricted in its movement in the width direction D2 more than in its movement in the length direction D1. This allows the weighted object 24 to be distributed evenly within the weighted bag 20A. This provides the user A with a sense of appropriate weight. This provides the user A with a sense of security and allows for a stable sleep.

[0076] Various embodiments of the weighted blanket according to the present disclosure have been described above. However, the weighted blanket according to the present disclosure is not limited to the contents of the various embodiments described above 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 weighted blanket according to the present disclosure can be changed as appropriate within the scope of the gist described above. The weighted blanket according to the present disclosure may also be a weighted blanket that combines multiple forms of the first and second embodiments described above.

[0077] For example, in the above embodiment, all of the weighted bags in weighted blanket 1 are cross-shaped weighted bags 20, and all of the weighted bags in weighted blanket 2 are striped weighted bags 20A. However, weighted blankets 1 and 2 may have a mixture of cross-shaped weighted bags 20 and striped weighted bags 20A. Even in this case, the same effects as those of the above embodiment can be obtained. Furthermore, when striped weighted bags 20A are placed in the center portion 202, for example, the distribution of weighted objects 24 in the center portion 202 can be made more uniform when the weighted blanket is turned over.

[0078] In the above-described embodiment, the weighted bag 20, 20A has an internal space divided into four sections. However, the internal space of the weighted bag 20, 20A may be divided into two, three, five, or more sections. Furthermore, the internal space of the weighted bag does not have to be divided. For example, the internal space of the weighted bag 20, 20A may be divided into eight sections. In this case, the weighted bag may have three horizontal stitches 23a and one vertical stitch 23b. Providing the horizontal stitches 23a and the vertical stitch 23b in this manner can more reliably prevent uneven distribution of the weighted object 24 in the weighted bag 20, 20A, making the weight of the weighted blanket 1, 2 more uniform. Therefore, the weighted object 24 can be distributed evenly, further reducing discomfort when using the weighted blanket 1, 2.

[0079] In the above embodiment, six weighted bags 20 are arranged on the inner surface 15 of the side fabric 10. However, five or fewer weighted bags 20 may be arranged on the inner surface 15, or seven or more weighted bags 20 may be arranged. In this case, the same effects as those of the above embodiment can be obtained.

[0080] In the above embodiment, the weighted bags 20 are arranged at both end portions 201 and the central portion 202. However, the weighted bag 20 does not have to be arranged at the central portion 202. In this case, the weight of the weighted blanket 1 on the body of the user A becomes even lighter, making it easier for the user A to turn over in his sleep.

[0081] In the above embodiment, the weight bag placement area 17 has been described as having four first buttons 16. However, the weight bag placement area 17 may have three or fewer first buttons 16, or may have five or more first buttons 16. Even in this case, the same effect as in the above embodiment can be obtained. The same applies to the number of second buttons 21 of the weight bag 20.

[0082] In the above-described embodiment, the weighted blanket 1 is described such that, when in use, the lengths of the first side 10a and the third side 10c are shorter than the lengths of the second side 10b and the central imaginary line 11. However, the lengths of the first side 10a and the third side 10c of the weighted blanket 1 when in use may be longer than the lengths of the second side 10b and the central imaginary line 11. Even in this case, the same effects as those of the above-described embodiment can be obtained.

[0083] In the above embodiment, the weighted bag 20 has been described as being square-shaped with four sides of equal length. However, the weighted bag 20 may also be rectangular, circular, or oval. In this manner, the shape of the weighted bag 20 is not particularly limited. For example, the length of the horizontal side 20a of the weighted bag 20 may be longer than the length of the vertical side 20b. The length of the horizontal side 20a of the weighted bag 20 may also be shorter than the length of the vertical side 20b. In this case, the same effects as those of the above embodiment can be obtained.

[0084] In the above embodiment, the weight bag 20 and the side fabric 10 are detachably fastened to each other by the first button 16 and the second button 21. However, the weight bag 20 and the side fabric 10 may be detachably fastened to each other by, for example, a hook-and-loop fastener or a string. In this way, the means for fastening the weight bag 20 to the side fabric 10 (the type of fastening member) is not particularly limited.

[0085] In the above-described embodiment, the first button 16 is a female snap button, and the second button 21 is a male snap button. However, the first button 16 may be a male snap button, or the second button 21 may be a female snap button. In these cases, the same effects as those of the above-described embodiment can be obtained.

[0086] The weighted blanket 1 according to this embodiment may be used in combination with bedding capable of distributing body pressure, such as a body pressure distribution mattress. That is, the weighted blanket 1 may be placed on the body pressure distribution mattress. User A may use bedding that includes the weighted blanket 1 and a body pressure distribution mattress. In this case, pressure can be distributed so that the weight of the weighted object 24 of the weighted blanket 1 is not applied excessively to User A, and User A can be prevented from sinking into the bedding. This further improves the sleeping comfort of User A.

[0087] Various experiments using the weighted blankets according to the examples will be described below. The bedding according to the present disclosure is not limited to the following examples. In these experiments, a comparison was made between using a blanket according to a comparative example and using the weighted blanket according to the examples in combination. The specifications of the weighted blankets according to the examples and the blankets according to the comparative example are as follows: (Example) The weighted blanket according to the example was the weighted blanket 1 according to the first embodiment described above. The weighted blanket according to the example includes six weighted bags 20 containing weighted objects 24 and a side fabric 10 covering the six weighted bags 20, with the six weighted bags 20 fixed to the inner surface 15 of the side fabric 10. (Comparative Example) The blanket in the comparative example does not have a weighting bag and is not weight adjustable. In the blanket in the comparative example, contents are stored inside the outer fabric, and the outer fabric is quilted.

[0088] FIG. 9 shows the relaxation score for the weighted blanket according to the embodiment. The "relaxation score" is an index used to visualize the relaxed state of the subject. The higher the relaxation score, the more relaxed the subject. The horizontal axis of FIG. 9 indicates the results when using the blanket according to the comparative example and the weighted blanket according to the embodiment. In FIG. 9 and FIGS. 10 and 11 described below, the shaded rectangles indicate the results when using the weighted blanket according to the embodiment, and the unshaded rectangles indicate the results when using the blanket according to the comparative example. The vertical axis of FIG. 9 indicates the relaxation score.

[0089] The top of the rectangular portion in Figure 9 indicates the average relaxation score. The number of subjects in the relaxation score measurement was three. To measure the relaxation score, an electroencephalograph was attached to each subject lying on the weighted blanket of the example and the blanket of the comparative example, and the subject's brain waves were acquired. The relaxation score value was then calculated using a program with a unique algorithm based on the intensity of the acquired brain wave data. The relaxed state of each subject was determined by the presence or absence of alpha waves or by comparison with brain waves in other frequency bands. As shown in Figure 9, it was suggested that using the weighted blanket of the example made it easier for each subject to relax than using the blanket of the comparative example.

[0090] FIG. 10 shows salivary amylase concentrations when using the weighted blanket according to the embodiment and when using the blanket according to the comparative example. The amount of salivary amylase secreted varies depending on sympathetic nervous function. Therefore, the degree of sympathetic nervous activity of the subject can be measured from the salivary amylase concentration. A high value of salivary amylase concentration indicates that sympathetic nervous activity is more active than when the value of salivary amylase concentration is low. Therefore, the value of salivary amylase concentration corresponds to the stress level of the subject. The "stress level" is the degree of stress felt by the subject. When sympathetic nervous activity is active, a higher stress level value is output than when sympathetic nervous activity is inactive.

[0091] The horizontal axis of Figure 10 shows the results when the weighted blanket according to the example was used and when the blanket according to the comparative example was used. The top of the rectangular portion shown in Figure 10 indicates the average salivary amylase concentration. The vertical axis of Figure 10 shows the salivary amylase concentration (unit: [kIU / L]). The number of subjects in the measurement of salivary amylase concentration was six. As shown in Figure 10, the salivary amylase concentration value when the weighted blanket according to the example was used was lower than the salivary amylase concentration value when the blanket according to the comparative example was used, suggesting that the activity of the sympathetic nerves of each subject was suppressed. Therefore, it was found that the use of the weighted blanket according to the example gave the subjects a greater sense of security than the use of the blanket according to the comparative example.

[0092] Figure 11 shows the results of subjective evaluations of the weighted blanket according to the example. The subjective evaluations were conducted by six subjects on a four-point scale. The horizontal axis of Figure 11 shows the sense of relaxation, sense of stress, sense of security, softness to the touch, fit, comfort, stuffiness, and warmth when using the weighted blanket according to the example and the blanket according to the comparative example. The vertical axis of Figure 11 shows the average value of the subjective evaluation results.

[0093] The top of the rectangular portion in Figure 11 shows the average score given by subjective evaluation. The scores given by subjective evaluation were: 4 = "very much," 3 = "somewhat," 2 = "not much," and 1 = "not at all." As shown in Figure 11, when using the weighted blanket according to the example, it was suggested that the sense of relaxation, fit, and warmth were particularly improved compared to when using the blanket according to the comparative example.
