Description

[Technical Field]

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

[0002] Japanese Patent Application Laid-Open Publication No. 2016-123545 describes a bedding for a user to rest on. This bedding includes a non-breathable bag, an air intake / exhaust valve provided in the bag for opening and closing airflow inside and outside the bag, and multiple elastic foam bodies packed into the bag's internal space in a compressed state to the bag's maximum capacity. With this bedding, by applying an external force to the bag while the air intake / exhaust valve is open to airflow, air can be released from the internal space, thinning the bag.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-123545 Summary of the Invention [Problem to be solved by the invention]

[0004] In the bedding described above, when compressing the bedding by applying an external force to the bag, it is conceivable that the worker compressing the bedding would apply the external force to the bag by directly pressing their body against the bag. However, with such bedding, it is necessary to directly press the worker's body against the bag to guide the air inside the bag to the intake / exhaust valve, which can be troublesome for the worker.

[0005] The present disclosure aims to provide bedding and a compression bar that can easily compress a bag body. [Means for solving the problem]

[0006] The bedding according to the present disclosure comprises a bag body formed in a non-breathable bag shape, an attachment part provided on the bag body for attaching a compression rod for compressing the bag body, and a circulation part provided on the bag body for opening and closing the circulation of air inside and outside the bag body, the attachment part having an opening for inserting the compression rod, and when the circulation part is open, the bag body is compressed by the compression rod inserted into the attachment part from the opening, and air flows out from inside the bag body to outside the bag body via the circulation part. The attachment portion is formed in a bag shape having an opening.

[0007] In the bedding according to the present disclosure, when the non-breathable bag is compressed by a compression rod inserted into the attachment part through the opening while the flow passage is open, air flows from inside the bag to outside the bag through the flow passage. Therefore, a worker compressing the bedding can fold the bag while compressing it by pressing the compression rod attached to the attachment part against the bag. This makes it easier to allow air to flow from inside the bag to outside the bag than when the worker presses the bag directly against the bag. Therefore, the bag can be easily compressed.

[0008] The bag body may have a rectangular shape having a pair of long sides and a pair of short sides, the attachment portion being provided on one of the pair of short sides of the bag body, and the circulating portion being provided on at least one of two corners formed by the other short side different from the one short side and each of the pair of long sides. In this case, a compression rod is attached to the attachment portion provided on one of the pair of short sides of the bag body, and the compression rod is pressed against the bag body to compress the bag body. At this time, the bag body can be folded in a direction from one short side to the other short side while being compressed by the compression rod. Air inside the bag body flows out of the bag body through the circulating portion provided on at least one of the two corners formed by the other short side and each of the pair of long sides. This allows air inside the bag body to more reliably flow out through the circulating portion, making it easier to compress the bag body.

[0009] The attachment portion may be provided along the entirety of one of the short sides. In this case, the compression bar is attached to the attachment portion provided along the entirety of one of the short sides of the bag body. Therefore, by pressing the compression bar extending along the entire short side of the bag body against the bag body and moving the compression bar along the long side of the bag body, the entire bag body can be efficiently compressed.

[0010] The bedding may further include a connecting member provided on at least one of a pair of long sides of the bag for connecting the bag to another bag. In this case, the long side of the bag can be connected to the long side of the other bag via the connecting member.

[0011] The mounting portion may be bag-shaped with an opening, and the opening may have a retaining portion for preventing the compression rod from coming out of the mounting portion. In this case, the compression rod inserted into the mounting portion through the opening can be made less likely to come out of the mounting portion. Therefore, since the compression rod can be made less likely to come out of the mounting portion when compressing the bag body with the compression rod, the bag body can be compressed more efficiently.

[0012] The compression rod according to the present disclosure is a compression rod used in the bedding described above, which is inserted through the opening of the attachment part and compresses the bag body, causing air to flow from the inside of the bag body to the outside of the bag body through the flow part. The compression rod has a compression portion that compresses the bag body and a gripping portion that is gripped by an operator, and the compression rod has a length in a first direction and a width in a second direction that intersects with the first direction, and both ends of the gripping portion in the second direction are located closer to the center of the compression rod in the second direction than both ends of the compression portion in the second direction.

[0013] In the compression bar according to the present disclosure, when the air-impermeable bag body is compressed by the compression bar inserted into the attachment part through the opening while the flow passage is open, air flows from the interior of the bag body to the exterior of the bag body through the flow passage. Therefore, a worker compressing bedding can fold the bag body while compressing it by pressing the compression bar attached to the attachment part against the bag body. This makes it easier to force air out of the bag body compared to compressing the bag body by directly pressing the worker's body against the bag body. Therefore, the bag body can be easily compressed.

[0014] The compression rod may have a compression portion for compressing the bag body, and the compression portion may have a flat shape, whereby the bag body can be more easily compressed by pressing the compression portion having a flat shape against the bag body. [Effects of the Invention]

[0015] According to the present disclosure, the bag can be easily compressed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, embodiments of the bedding and compression rod 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. In addition, the drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional proportions and the like are not limited to those shown in the drawings.

[0018] First, we will explain the bedding according to the present disclosure. "Bedding" refers to anything that a user's body rests on when they rest or sleep. "Bedding" typically refers to bedding such as mattresses and futons, bedding such as comforters, cushions, bed pads, floor cushions, or pillows.

[0019] A "user" is a person who uses bedding by bringing their body into contact with the bedding. For example, if the bedding is a quilt, the "user" is a person who puts the bedding over their body. For example, if the bedding is a mattress, the "user" is a person who places their body on the bedding. In this case, as a specific example, the "user" is a person who lies on the bedding after purchasing it, or a person who lies on the bedding in order to purchase it. In the present disclosure, the work of compressing the bedding is performed by a worker. A "worker" is, for example, a person who compresses or expands the bedding. A "worker" is typically a person who purchases the bedding or a person who sells the bedding.

[0020] [First embodiment] First, a mattress 1, which is an example of bedding according to the first embodiment, will be described. FIG. 1 is a perspective view that schematically shows the mattress 1, which is an example of bedding according to the first embodiment. As shown in FIG. 1, the mattress 1 has an overall rectangular shape. Hereinafter, the direction in which the long sides of the mattress 1 extend will be referred to as the "longitudinal direction," and the direction in which the short sides of the mattress 1 extend will be referred to as the "short direction." The mattress 1 comprises a top sheet member 2 and a back sheet member 3 located on the back side of the top sheet member 2.

[0021] The front sheet member 2 and the back sheet member 3 are both non-breathable. Each of the front sheet member 2 and the back sheet member 3 has a rectangular shape. That is, each of the front sheet member 2 and the back sheet member 3 has a pair of long sides extending in the longitudinal direction A1 and a pair of short sides extending in the transverse direction A2. The length of the short sides of the back sheet member 3 is approximately the same as the length of the short sides of the front sheet member 2. For example, the length of the long sides of the back sheet member 3 is longer than the length of the long sides of the front sheet member 2. The front sheet member 2 and the back sheet member 3 are made of a non-breathable material, such as cotton or polyester knitted or woven fabric, which is coated with a TPU (thermoplastic polyurethane elastomer), a PU (polyurethane), or a PVC (polyvinyl chloride) coating. The front sheet member 2 and the back sheet member 3 may also be made of a non-breathable material in the form of a thin sheet of the aforementioned coating material. However, the materials of the front-side sheet member 2 and the back-side sheet member 3 are not limited to the above examples and can be changed as appropriate.

[0022] The mattress 1 includes a bag body 4 formed in a bag shape with no air permeability. For example, the bag body 4 is composed of a front sheet member 2 and a part of a back sheet member 3. "Having no air permeability" includes both a case where the entire bag body is non-breathable and a case where only a part of the bag body is non-breathable. The bag body 4 is the part on which the user's body rests. The bag body 4 is formed in a bag shape by joining the front sheet member 2 and the back sheet member 3 together. As an example, the front sheet member 2 and the back sheet member 3 are welded to each other.

[0023] The bag body 4 has a rectangular shape with a pair of long sides 4a, 4b and a pair of short sides 4c, 4d. One long side 4a is formed by joining one long side of the front sheet member 2 and one long side of the back sheet member 3. The other long side 4b is formed by joining the other long side of the front sheet member 2 and the other long side of the back sheet member 3.

[0024] For example, one short side 4c is formed by joining one short side of the front sheet member 2 and one short side of the back sheet member 3. The other short side 4d is formed by joining the other short side of the front sheet member 2 and the other short side of the back sheet member 3. As an example, a user of the mattress 1 rests his / her head on one side of the bag body 4 in the longitudinal direction A1 (for example, on the side of one short side 4c) and his / her legs on the other side of the bag body 4 in the longitudinal direction A1 (for example, on the side of the other short side 4d). Also, a user of the mattress 1 can rest his / her head on the other short side 4d of the bag body 4 and his / her legs on the side of the one short side 4c of the bag body 4.

[0025] The interior of the bag body 4 (between the front sheet member 2 and the back sheet member 3) is filled with a cushioning material (not shown) that bears the weight of the user of the mattress 1. The cushioning material is made of, for example, urethane. When an air valve (flow section) 6, which will be described later, is closed, the bag body 4 stores the cushioning material airtight inside the bag body 4.

[0026] The mattress 1 has an attachment portion 5 for attaching a compression rod 20, which will be described later. The attachment portion 5 is formed into a bag shape having an opening 5e, for example, by folding back and welding the back sheet member 3. The attachment portion 5 is provided on one of the short sides 4c of the bag body 4. The attachment portion 5 has a rectangular shape having a pair of long sides 5a, 5b and a pair of short sides 5c, 5d.

[0027] One long side 5a is formed by folding back a portion of the back sheet member 3 that protrudes from the front sheet member 2 in the longitudinal direction A1. The other long side 5b is formed as one short side 4c of the bag body 4 by joining (for example, welding) the end of the folded back back sheet member 3 in the longitudinal direction A1 to one short side of the front sheet member 2. The attachment portion 5 is provided over the entire one short side 4c. In this disclosure, "the entire short side" refers to approximately the entire short side. "The entire short side" also includes a state where the attachment portion is shorter or longer than the entire short side, as long as the effect is not changed.

[0028] Each of the pair of short sides 5c, 5d is formed, for example, by folding back in the longitudinal direction A1 a portion of the back sheet member 3 that protrudes from the front sheet member 2 in the longitudinal direction A1. One of the short sides 5c is closed by joining a pair of back sheet members 3 that are folded back and aligned vertically. In contrast, the other short side 5d is open, unlike the one short side 5c. As a result, the other short side 5d forms an opening 5e for inserting the compression rod 20. For example, the opening 5e is formed by a pair of back sheet members 3 that are folded back in the longitudinal direction A1 and aligned vertically. For example, the opening 5e extends along the longitudinal direction A1 at one end of the mounting portion 5 in the transverse direction A2.

[0029] The mattress 1 is provided with an air valve 6 that opens and closes the flow of air between the inside and outside of the bag body 4. When the air valve 6 is in an open state, it allows air to flow between the inside and outside of the bag body 4. When the air valve 6 is in a closed state, it makes the inside of the bag body 4 airtight. In this embodiment, the air valve 6 is provided in a corner formed by the other short side 4d and the other long side 4b of the bag body 4. However, the air valve 6 may also be provided in a corner formed by the other short side 4d and one long side 4a of the bag body 4. Furthermore, the air valve 6 may also be provided in both of the two corners formed by the other short side 4d and each of the pair of long sides 4a, 4b. In this case, by providing the mattress 1 with two air valves 6, air can be more efficiently circulated between the inside and outside of the bag body 4.

[0030] FIG. 2 is a plan view schematically showing the mattress 1 shown in FIG. 1. FIG. 2 illustrates the back side (back sheet member 3) of the mattress 1. As shown in FIG. 2, the mattress 1 includes two hem fabrics 7, 8 and two line fasteners 9 (connecting members). Each of the hem fabrics 7, 8 extends along the longitudinal direction A1 of the mattress 1 and is folded back in the lateral direction A2 at the long sides of the mattress 1. The hem fabric 7 is provided on one long side 4a of the bag body 4 and one short side 5c of the attachment portion 5. The hem fabric 8 is provided on the other long side 4b of the bag body 4. The lengths of the hem fabrics 7, 8 are not particularly limited, but are, for example, longer than the line fastener 9.

[0031] The line fasteners 9 are components for connecting the bag body 4 to another bag body other than the bag body 4. Each of the two line fasteners 9 extends in the longitudinal direction A1 of the mattress 1 and is sewn along the hems 7, 8, respectively. In this embodiment, the line fasteners 9 are exemplified as connecting members, but the connecting member may be a component other than the line fasteners 9 as long as it is a component for connecting the bag body 4 to another bag body other than the bag body 4. For example, the connecting member may be a hook-and-loop fastener or a hook.

[0032] 3 is an enlarged view of the region R1 in FIG. 1 where the opening 5e is provided. As shown in FIG. 3, the opening 5e has a hook and loop fastener 10 (a retaining portion) for preventing the compression bar 20 from coming out of the mounting portion 5. The hook and loop fastener 10 is provided on the inside of the opening 5e. For example, the hook and loop fastener 10 is provided on the inside of the opening 5e, on the long side 5b side. The hook and loop fastener 10 extends in the longitudinal direction A1 on the inside of the opening 5e. The hook and loop fastener 10 is joined to a part of the inner surface of the opening 5e.

[0033] In the example of Figure 3, the hook and loop fastener 10 joins with a portion of the inner surface of the opening 5e located directly above the hook and loop fastener 10. When the compression bar 20 is inserted into the opening 5e, the hook and loop fastener 10 joins with a portion of the inner surface of the opening 5e, causing the hook and loop fastener 10 to close a portion of the opening 5e. When the hook and loop fastener 10 closes a portion of the opening 5e in this manner, the compression bar 20 is fastened by the opening 5e, making it difficult for the compression bar 20 to come out of the opening 5e. In this embodiment, the hook and loop fastener 10 is used as an example of a retaining portion for the compression bar 20, but the retaining portion may be a hook, and the type of component constituting the retaining portion is not particularly limited.

[0034] 4(a) and 4(b) are enlarged views of region R2 in FIG. 1 where air valve 6 is provided. As shown in FIGS. 4(a) and 4(b), air valve 6 has a threaded portion 6a and a lid portion 6b. Threaded portion 6a is attached to a corner of bag body 4. Threaded portion 6a is formed, for example, in a cylindrical shape, allowing air to circulate between the inside and outside of bag body 4. Threads and a screw groove (external thread) for threading lid portion 6b are formed on the outer circumferential surface of threaded portion 6a.

[0035] The lid portion 6b has, for example, a cylindrical shape with a bottom. The lid portion 6b can be attached to and detached from the threaded portion 6a by rotating it. As shown in FIG. 4(a), the lid portion 6b is attached to the threaded portion 6a by rotating it in one direction (e.g., clockwise) around the central axis L of the threaded portion 6a. On the other hand, as shown in FIG. 4(b), the lid portion 6b is detached from the threaded portion 6a by rotating it in the opposite direction (e.g., counterclockwise) around the central axis L. The worker compressing the mattress 1 can open and close the air valve 6 by rotating the lid portion 6b. The materials and shapes of the components constituting the air valve 6 are not limited to the above example and can be changed as appropriate.

[0036] Next, a compression rod 20 according to this embodiment will be described. FIG. 5 is a perspective view showing the compression rod 20. As shown in FIG. 5, the compression rod 20 has, for example, a flat shape extending along a first direction D1. The compression rod 20 has a length in the first direction D1 and a width in a second direction D2 intersecting the first direction D1. The first direction D1 is the longitudinal direction of the compression rod 20, and the second direction D2 is the width direction of the compression rod 20. The compression rod 20 may be made of plastic, wood, or metal; the material of the compression rod 20 is not particularly limited. The compression rod 20 has a compression portion 21 that compresses the bag body 4 and a grip portion 22 that is gripped by an operator.

[0037] The compressed portion 21 has a flat shape extending in the first direction D1. The compressed portion 21 has flat surfaces on both the front and back sides that extend in both the first direction D1 and the second direction D2. The flat surfaces of the compressed portion 21 are, for example, flat surfaces. However, the flat surfaces of the compressed portion 21 do not have to be flat surfaces, and may be curved surfaces that curve so as to bulge outward from the compressed portion 21. When the compressed portion 21 is cut along a plane perpendicular to the first direction D1, the cross section of the compressed portion 21 is, for example, rectangular. However, the cross-sectional shape of the compressed portion 21 may also be an oval shape (or an ellipse shape), as long as it has a major axis and a minor axis.

[0038] For example, the length of the compressed portion 21 in the first direction D1 is longer than the length (length in the short direction A2) of the attachment portion 5. Furthermore, the length of the compressed portion 21 in the second direction D2 is shorter than the width (length in the longitudinal direction A1) of the attachment portion 5. As an example, the length of the compressed portion 21 in the second direction D2 is 5 cm or more and 8 cm or less.

[0039] The grip portion 22 extends from the compression portion 21 along the first direction D1. That is, the grip portion 22 extends in the first direction D1 from one end of the compression portion 21 in the first direction D1. For example, both ends of the grip portion 22 in the second direction D2 are located closer to the center (inner side) of the compression bar 20 in the second direction D2 than both ends of the compression portion 21 in the second direction D2. For example, the compression bar 20 has a transition portion where the compression portion 21 transitions to the grip portion 22. In this transition portion, the length (width) of the compression bar 20 in the second direction D2 becomes shorter as it moves from the compression portion 21 toward the grip portion 22.

[0040] In this embodiment, the grip portion 22 has a flat shape. For example, the shape of the grip portion 22 is the same as the shape of the compression portion 21. However, the shape of the grip portion 22 does not have to be the same as the shape of the compression portion 21. For example, the shape of the grip portion 22 may be a columnar shape (for example, a rectangular columnar or a cylindrical shape). The size of the grip portion 22 may be small enough to be held by an operator's hand. The shape and size of the grip portion 22 have been described above, but the shape and size of the grip portion 22 are not limited to the above example and can be changed as appropriate.

[0041] For example, the length of the compressed portion 21 in the first direction D1 is longer than the length of the grip portion 22 in the first direction D1. For example, the length of the compressed portion 21 in the second direction D2 is longer than the length of the grip portion 22 in the second direction D2. For example, the flat surface of the compressed portion 21 is continuous with the flat surface of the grip portion 22. The thickness of the compressed portion 21 and the grip portion 22 (the length in the direction intersecting both the first direction D1 and the second direction D2) is, for example, 0.5 cm or more and 3.0 cm or less (for example, 1.0 cm).

[0042] The shape, length, etc. of the compression rod 20 have been described above. However, the shape and length of the compression rod 20 are not limited to the above example and can be changed as appropriate. For example, the compression rod 20 may be formed in a cylindrical shape. In this case, the diameter of the compression rod 20 may be 2 cm or more and 5 cm or less.

[0043] Next, a method for compressing the mattress 1 according to this embodiment will be described. As shown in Fig. 6, first, the worker compressing the mattress 1 inserts the compression portion 21 of the compression rod 20 into the mounting portion 5 through the opening 5e. As described above, the length of the compression portion 21 in the first direction D1 is longer than the length of the mounting portion 5 (the length in the short direction A2). Therefore, when the compression rod 20 is attached to the mounting portion 5, a portion of the compression portion 21 protrudes from the opening 5e of the mounting portion 5.

[0044] As shown in FIG. 4(b), the worker opens the air valve 6. The worker rotates the lid portion 6b in one direction to remove the lid portion 6b from the screw portion 6a. This allows air to circulate inside and outside the bag body 4. Next, the worker closes a portion of the opening 5e of the attachment portion 5 into which the compression rod 20 has been inserted, using the hook-and-loop fastener 10 (see FIG. 3) of the opening 5e. This makes it difficult for the compression rod 20 to come out of the opening 5e, thereby preventing the compression rod 20 from coming out of the attachment portion 5 while the worker is compressing the bag body 4 with the compression rod 20.

[0045] As shown in Figure 7, the worker compresses the bag body 4 with the compression rod 20 inserted into the attachment part 5, while causing air to flow from inside the bag body 4 to outside the bag body 4 via the air valve 6. At this time, the worker compresses the bag body 4 with the mattress 1 placed on a hard surface such as the floor or a desk. In this embodiment, the worker compresses the bag body 4 by pressing the compression part 21 of the compression rod 20 against the bag body 4.

[0046] At this time, the flattened compressed portion 21 is pressed against the bag body 4, causing the air inside the portion of the bag body 4 against which the compressed portion 21 is pressed to move toward the short side 4d. That is, by tilting the compressed portion 21 toward the short side 4d of the bag body 4 and pressing the flat surface of the compressed portion 21 against the bag body 4, the air inside the portion of the bag body 4 against which the flat surface of the compressed portion 21 is pressed moves toward the short side 4d. In this manner, the compressed portion of the bag body 4 is repeatedly pressed from one short side 4c toward the other short side 4d, and the compressed portion of the bag body 4 is wrapped around the compressed portion 21. By pressing the flat surface of the compressed portion 21 against the bag body 4, the worker can apply a uniform external force to the bag body 4.

[0047] The worker wraps the compressed bag body 4 around the compression section 21 and folds the bag body 4 from one short side 4c to the other short side 4d. Then, the air valve 6 is closed (see FIG. 4(a)). This prevents air from flowing into the bag body 4 through the air valve 6. This allows the bag body 4 to maintain its compressed state.

[0048] Next, as shown in Figures 8 and 9, the worker removes the compression rod 20 from the opening 5e of the attachment part 5. The worker stores the compressed mattress 1 in the storage bag 30. This makes it easy to carry the mattress 1. In this embodiment, the storage bag 30 has a storage section 31 with an opening that stores the mattress 1, a binding string 32 provided at the opening of the storage section 31, and a fastener 33 provided slidably relative to the binding string 32.

[0049] When storing the mattress 1 in the storage bag 30, the worker places the compressed mattress 1 into the opening of the storage section 31, thereby storing the mattress 1 in the storage section 31. The worker closes the opening of the storage section 31 by pulling the fastening string 32. The worker then slides the fastener 33 so as to press it against the opening of the storage section 31, thereby maintaining the opening of the storage section 31 in a closed state. Through the above steps, the worker can easily carry the mattress 1 after compressing it.

[0050] When a user uses the mattress 1, the compressed mattress 1 is inflated. In this case, the worker inflating the bedding removes the mattress 1 from the storage bag 30 and then opens the air valve 6 of the mattress 1. With the air valve 6 open, air enters the bag body 4 through the air valve 6, causing the bag body 4 to inflate. Alternatively, the worker may attach an air injector to the open air valve 6 to inflate the bag body 4. With the bag body 4 inflated, the mattress 1 is ready for use by the user.

[0051] Next, the effects of the mattress 1 and compression rod 20 according to this embodiment will be described. As shown in FIGS. 6 and 7 , in the mattress 1 and compression rod 20 according to this embodiment, when the air valve 6 is open, the non-breathable bag body 4 is compressed by the compression rod 20 inserted into the attachment portion 5 through the opening 5e, causing air to flow from inside the bag body 4 to the outside of the bag body 4 via the air valve 6. Therefore, a worker compressing the mattress 1 can fold the bag body 4 while compressing it by pressing the compression rod 20 attached to the attachment portion 5 against the bag body 4. This makes it easier to flow air from inside the bag body 4 to the outside of the bag body 4 than when the worker presses their body directly against the bag body 4 to compress it. Therefore, the bag 4 can be compressed easily.

[0052] The bag body 4 is also provided with an attachment portion 5 for attaching a compression rod 20 for compressing the bag body 4. This prevents the compression rod 20 from coming off the mattress 1 when the worker compresses the bag body 4. The bag body 4 is also provided with an air valve 6, and when the worker compresses the bag body 4, the air inside the bag body 4 flows out of the bag body 4 via the air valve 6. This allows the air inside the bag body 4 to more easily flow out of the bag body 4 via the air valve 6, compared to, for example, a case where the bag body does not have an air valve 6 and the air flows out from the breathable bag body itself. This means that the bag body 4 can be compressed easily.

[0053] As shown in FIG. 1 , the bag body 4 according to this embodiment has a rectangular shape with a pair of long sides 4a, 4b and a pair of short sides 4c, 4d. The attachment portion 5 is provided on one of the short sides 4c, 4d of the bag body 4. The air valve 6 is provided on a corner formed by the other short side 4d, which is different from the one short side 4c, and the other long side 4b. In this case, a compression rod 20 is attached to the attachment portion 5 provided on one of the pair of short sides 4c, 4d of the bag body 4, and the compression rod 20 is pressed against the bag body 4 to compress the bag body 4. At this time, the bag body 4 can be folded in a direction from one short side 4c to the other short side 4d while being compressed by the compression rod 20. Air inside the bag body 4 flows out of the bag body 4 through the air valve 6 provided on the corner formed by the other short side 4d and the other long side 4b. Therefore, the air inside the bag body 4 can be more reliably released through the air valve 6, and the bag body 4 can be compressed more easily.

[0054] In this embodiment, the attachment portion 5 is provided over the entire one short side 4c. In this case, the compression rod 20 is attached to the attachment portion 5 provided over the entire one short side 4c of the bag body 4. As a result, the compression rod 20 extending over the entire one short side 4c is pressed against the bag body 4 and moved along the long sides 4a and 4b of the bag body 4, thereby enabling the entire bag body 4 to be efficiently compressed.

[0055] As shown in Figure 2, the mattress 1 according to this embodiment further includes line fasteners 9 provided on a pair of long sides 4a, 4b of the bag body 4 for connecting the bag body 4 to another bag body. In this case, the long sides 4a, 4b of the bag body 4 can be connected to the long sides of the other bag body via the line fasteners 9. This allows the connected mattresses 1 to be laid on the floor or the like in the event of a disaster, for example, thereby providing a large-sized mattress that reduces the hardness and coldness of the floor or the like.

[0056] In this embodiment, the mounting part 5 is bag-shaped and has an opening 5e, and the opening 5e has a hook-and-loop fastener 10 for preventing the compression rod 20 from slipping out of the mounting part 5. In this case, the compression rod 20 inserted into the mounting part 5 through the opening 5e can be made less likely to slip out of the mounting part 5.

[0057] 5, in this embodiment, the compression rod 20 has a compression section 21 for compressing the bag body 4, and the compression section 21 has a flat shape. This makes it possible to compress the bag body 4 more easily by pressing the compression section 21 having a flat shape against the bag body 4.

[0058] [Second embodiment] Next, a duvet 1A, which is an example of bedding according to a second embodiment, will be described with reference to Figs. 10(a) and 10(b). The duvet 1A differs from the mattress 1 according to the first embodiment in that it includes a bag body 40 that is different from the bag body 4. Below, descriptions that overlap with the bedding (mattress 1) of the first embodiment will be omitted as appropriate. Fig. 10(a) is a plan view that schematically shows the duvet 1A. Fig. 10(b) is a cross-sectional view that schematically shows the duvet 1A.

[0059] As shown in Figures 10(a) and 10(b), the bag body 40 has an outer layer 41 and a cushioning material 42 contained in the outer layer 41. For convenience, the cushioning material 42 is shown in solid lines in the example of Figure 10(a). However, because the cushioning material 42 is contained in the outer layer 41, the cushioning material 42 is not actually visible when the comforter 1A is viewed from above.

[0060] The outer fabric 41 has a rectangular shape having a pair of long sides 41a, 41b and a pair of short sides 41c, 41d. An attachment portion 5 is provided on one short side 41c of the outer fabric 41. An air valve 6 is provided at the corner formed by the other short side 41d of the outer fabric 41 and the other long side 41b of the outer fabric 41. The outer fabric 41 may or may not be non-breathable. The outer fabric 41 is made of, for example, cloth.

[0061] The cushion material 42 has, for example, a rectangular shape. The cushion material 42 is non-breathable. The cushion material 42 is composed of a plurality of cells 43. Each of the plurality of cells 43 has a rectangular shape with chamfered corners (rounded rectangular shape). In this embodiment, the plurality of cushion materials 42 are arranged so as to line up along both the longitudinal direction B1 and the lateral direction B2 of the comforter 1A.

[0062] For example, multiple cells 43 are lined up along both the longitudinal direction B1 and the lateral direction B2 of the comforter 1A. That is, multiple cells 43 are arranged in a grid pattern in the comforter 1A. As an example, three cells 43 are lined up along the lateral direction B2 of the comforter 1A, and five cells 43 are lined up along the longitudinal direction B1 of the comforter 1A.

[0063] For example, through holes are provided in the wall portions constituting the cells 43. The through holes allow air to circulate between the inside and outside of the cells 43. Two adjacent cells 43 are joined together with their through holes aligned. This allows air to circulate between the multiple cells 43. An air valve 6 is connected to one cell 43 of the multiple cells 43. In this embodiment, the air valve 6 is connected to the cell 43 that is arranged at a corner formed by the other short side 41d and the other long side 41b of the outer layer 41.

[0064] As described above, with the comforter 1A and compression rod 20 according to the second embodiment, when the air valve 6 is open, the non-breathable bag body 40 is compressed by the compression rod 20 inserted into the attachment part 5 through the opening 5e, causing air to flow from inside the cushioning material 42 inside the bag body 40 to the outside of the bag body 40 via the air valve 6. Therefore, a worker compressing the comforter 1A can press the compression rod 20 attached to the attachment part 5 against the bag body 40 to compress it while folding it. As with the mattress 1 described above, this makes it easier for air to flow from inside the bag body 40 to the outside than when the worker presses their body directly against the bag body 40 to compress it. Therefore, the bag body 40 can be compressed easily.

[0065] Furthermore, in the second embodiment, the cushioning material 42 inside the bag body 40 is composed of a plurality of cells 43. As a result, when the compression rod 20 is pressed against the bag body 40 to fold it, the boundary between two adjacent cells 43 along the longitudinal direction B1 is easily breakable, making it easy to fold the bag body 40. Therefore, with the comforter 1A according to this embodiment, the bag body 40 can be folded even more easily.

[0066] Although the bedding and compression rod according to the present disclosure have been described above as embodiments, the bedding and compression rod according to the present disclosure are not limited to the above embodiments and can be modified as appropriate.

[0067] For example, in the first embodiment described above, the mounting portion 5 is formed in a bag shape having an opening 5e and is provided over the entire one short side 4c of the bag body 4. However, the mounting portion may be any portion that can attach the compression rod 20, and may be provided, for example, on a portion of one short side 4c. As an example, the mounting portion may be formed in an annular shape or on a portion of the short side 4c. For example, multiple mounting portions may be provided on one short side 4c. In this case, the multiple mounting portions 5 are provided on one short side 4c so as to be spaced apart from each other in the short direction A2. The mounting portion may be formed longer than one short side 4c of the bag body 4.

[0068] In the first embodiment described above, one short side 5c of the attachment portion 5 is closed by folding back and joining a pair of vertically arranged back-side sheet members 3. However, one short side 5c of the attachment portion 5 may be open, similar to the other short side 5d.

[0069] In this case, the mounting portion 5 has a cylindrical shape with one end and the other end in the longitudinal direction (e.g., the short-side direction A2) of the mounting portion 5 being open, so the compression rod 20 can be inserted and removed from either end of the mounting portion 5. As an example, an operator can insert the compression rod 20 from the other short side 5d (opening 5e) toward one short side 5c. This allows the operator to compress the bag body 4 by grasping both ends of the compression rod 20 in the first direction D1 with both hands. Therefore, by grasping the compression rod 20 with both hands and moving the compression rod 20 while pressing it against the bag body 4, the bag body 4 can be compressed more easily. In this case, the gripping portions 22 may extend from both ends of the compression portion 21 in the first direction D1.

[0070] In the first embodiment described above, an example has been described in which the bag body 4 and the attachment portion 5 are formed into a bag shape by welding the front sheet member 2 and the back sheet member 3 together. However, the method of joining the front sheet member 2 and the back sheet member 3 together can be changed as appropriate as long as the breathability of the bag body 4 is ensured. As an example, the front sheet member 2 and the back sheet member 3 may be joined together by sewing them.

[0071] In the first embodiment described above, an example has been described in which the mattress 1 is formed by welding together the front sheet member 2 and the back sheet member 3. However, the mattress 1 may also be formed from a single sheet member.

[0072] In the above-described embodiment, an example has been described in which the other short side 5d forms the opening 5e for inserting the compression rod 20. In the above-described embodiment, an example has been described in which the opening 5e extends along the longitudinal direction A1 at one end in the short side direction A2 of the mounting portion 5. However, the opening may be formed at a position other than the one end in the short side direction A2 of the mounting portion 5.

[0073] For example, the opening may be formed on the upper or lower surface of the attachment part 5 (the upper or lower surface of the attachment part 5 when the mattress 1 is in use (open state)). For example, the opening may be formed in the shape of a slit on the upper or lower surface of the attachment part 5. As an example, the slit-shaped opening may be formed on the other short side 5d of the attachment part 5, and may extend in the longitudinal direction A1 of the mattress 1 or the longitudinal direction B1 of the comforter 1A. Furthermore, the opening does not have to be slit-shaped, and may be rectangular, fan-shaped, circular, or elliptical. In this way, the shape and position of the opening can be changed as appropriate.

[0074] In the above-described embodiment, the mattress 1, the comforter 1A, the pouches 4, 40, and the attachment portion 5 each have a rectangular shape. However, these shapes are not particularly limited and can be changed as appropriate.

[0075] The compression rod 20 may be marked with an indication of the direction in which to insert it through the opening 5e of the mounting part 5. For example, the compression rod 20 shown in FIG. 5 may be marked with an arrow pointing in the opposite direction to the gripping part 22 (to the right in FIG. 5). Furthermore, instead of or together with the arrow, the compression part 21 may be marked with a statement indicating that the compression rod 20 should be inserted into the opening 5e of the mounting part 5 in the direction indicated by the arrow. In this case, the operator can easily understand the direction in which to insert the compression rod 20.

[0076] Furthermore, in the above-described embodiment, the present disclosure has been described as being applied to a mattress 1 and a comforter 1A, which are examples of bedding according to the present disclosure. However, the present disclosure is widely applicable to air filling devices that are used by filling a bag-shaped bag with air. For example, the present disclosure is also applicable to swim rings, beach balls, floats, etc.

[0077] That is, the air filling device is A bag body formed in a bag shape having air impermeability; an attachment portion provided on the bag body and for attaching a compression rod for compressing the bag body; a circulation part that is provided in the bag body and opens and closes the circulation of air between the inside and outside of the bag body, The mounting portion has an opening for inserting a compression rod, and when the flow passage portion is open, the bag body is compressed by the compression rod inserted into the mounting portion from the opening, causing air to flow from the inside of the bag body to the outside of the bag body through the flow passage portion.

[0078] In addition, the compression rod A compression rod used in the air filling device, When the bag is inserted through the opening of the attachment portion and compressed, air flows from the inside of the bag to the outside of the bag through the flow passage portion. [Explanation of symbols]
