[0017] Hereinafter, the present invention will be described in more detail based on the drawings, but the present invention is not limited in any way to these embodiments. Further, the longitudinal direction, width direction, and thickness direction in the present specification shall mean the longitudinal direction, width direction, and thickness direction shown in Figure 1.

[0018] The cushion C shown in Figure 1 has a plate-shaped cushion material 2 that is rectangular in plan view, and a cushion cover (hereinafter sometimes simply referred to as "cover") 1 that encloses the cushion material 2.

[0019] (Cushion Material) The cushion material 2 is a plate-shaped body that is rectangular in plan view, has a predetermined thickness, and has elasticity. When the cushion C is used as a mattress, examples of the material of the cushion material 2 include urethane foam, latex, polyethylene, cotton, and synthetic fibers. Among these, urethane foam, latex, and polyethylene are preferable. Urethane foam is more preferable from the viewpoints of body pressure dispersibility and processability. As the urethane foam, one having a three-dimensional network structure without cell membranes is recommended because it has air permeability and water permeability functions. The thickness of the cushion material 2 is not particularly limited, but when the cushion C is used as a mattress, a range of usually 20 mm or more and 300 mm or less is preferable. The lengths of the mattress in the longitudinal direction and the width direction are generally about 2000 mm and about 1000 mm. For example, when a mattress is configured by connecting three cushions C, the length of one cushion material 2 in the longitudinal direction is set to 1 / 3 of the length of the mattress in the longitudinal direction.

[0020] The cushion material 2 may have a structure in which plate-shaped elastic members having different characteristics are laminated. Further, the cushion material 2 may have one or both surfaces in the thickness direction subjected to profile processing. Furthermore, the cushion material 2 used in the present invention is not limited to a plate shape, and may be composed of, for example, a plurality of elastic block pieces.

[0021] (Cover) The cover 1 includes a cover body 3 that encloses the cushion material 2, and connectors 4a and 4b provided on both side surfaces in the width direction of the cover body 3.

[0022] (Cover body) The cover body 3 corresponds to the cushion material 2, is rectangular in plan view, and has a predetermined thickness. Specifically, the cover body 3 has a shape similar to the cushion material 2, and has an internal volume slightly larger than the cushion material 2.

[0023] An opening / closing member 11, which may be a fastener or the like, is provided continuously from the substantially central portion in the longitudinal direction of the side surface 31 and the side surface 32 facing each other in the width direction of the cover body 3, over the entire width direction of one side surface 34 in the longitudinal direction. By bringing the opening / closing member 11 into an open state, the cushion material 2 can be stored into and taken out of the cover body 3. The opening / closing member 11 is normally in a closed state, and is brought into an open state only when necessary.

[0024] As the material of the cover body 3, conventionally known materials such as fabric and resin sheet can be used, for example. In addition, the cover body 3 may have elasticity.

[0025] (Connector) The connectors 4a and 4b are composed of a first connection member 41, and a second connection member 42 that can be connected to and separated from the first connection member 41.

[0026] The first connecting member 41 consists of a belt material 411 made of fabric or the like, and a hook-and-loop fastener 412 attached to one end of the belt material 411 in the longitudinal direction. The other end of the belt material 411 in the longitudinal direction is attached to the cover body 3, and the other end is a free end. The hook-and-loop fastener 412 is attached to the side of the free end of the belt material 411 that faces the cover body 3. The second connecting member 42 is a hook-and-loop fastener, and is attached to the cover body 3 at a predetermined distance from the first connecting member 41 in the thickness direction. It is sufficient that the first connecting member 41 and the second connecting member 42 can be connected and separated, and it is also acceptable for the first connecting member 41 to have a hook-and-loop fastener and the second connecting member 42 to have a hook-and-loop fastener.

[0027] The first connecting member 41 and the second connecting member 42 are provided at both ends in the longitudinal direction of the side surfaces 31 and 32 of the cover body 3, which face each other in the width direction, separated by a predetermined distance in the thickness direction. More specifically, on one longitudinal end of the side surface 31 of the cover body 3 (the left end in Figure 1), the first connecting member 41 is provided on the upper side in the thickness direction and the second connecting member 42 is provided on the lower side, separated by a predetermined distance in the thickness direction. On the other longitudinal end (the right end in Figure 1), the second connecting member 42 is provided on the upper side in the thickness direction and the first connecting member 41 is provided on the lower side, separated by a predetermined distance in the thickness direction. In other words, the mounting positions of the first connecting member 41 and the second connecting member 42 in the thickness direction are reversed on one longitudinal end and the other longitudinal end of the side surface 31 of the cover body 3.

[0028] Furthermore, on the side surface 32 of the cover body 3, the mounting positions in the thickness direction of the first connecting member 41 and the second connecting member 42 at the end opposite the side surface 31 are reversed. That is, on the side surface 32 of the cover body 3, on one longitudinal end (the left end in Figure 1), the second connecting member 42 is provided on the upper side in the thickness direction and the first connecting member 41 is provided on the lower side, separated by a predetermined distance in the thickness direction. On the other longitudinal end (the right end in Figure 1), the first connecting member 41 is provided on the upper side in the thickness direction and the second connecting member 42 is provided on the lower side, separated by a predetermined distance in the thickness direction.

[0029] The female fasteners, which serve as third connecting members 43, are provided on the sides 33 and 34 of the cover body 3. More specifically, when the belt material 411 of the first connecting member 41 is bent to contact the outer circumferential surface of the cover body 3, the female fasteners, which serve as third connecting members 43, are provided at a position where the male fastener 412, provided on the free end side of the belt material 411, contacts the sides 33 and 34 of the cover body 3. In other words, on the side 33 of the cover body 3, the female fasteners, which serve as third connecting members 43, are provided on the lower side in the thickness direction on the front side in the width direction and on the upper side in the thickness direction on the rear side in the width direction. On the side 34 of the cover body 3, the female fasteners, which serve as third connecting members 43, are provided on the upper side in the thickness direction on the front side in the width direction and on the lower side in the thickness direction on the rear side in the width direction. Note that the third connecting member 43 only needs to be able to connect to and separate from the first connecting member 41, and it is also acceptable for the first connecting member 41 to have a female fastener and the third connecting member 43 to have a male fastener.

[0030] (Connecting the cushions) The cushion C according to the present invention can be connected in any desired number in the longitudinal direction. Figure 2 shows a mattress 9 formed by connecting three cushion C units in the longitudinal direction as shown in Figure 1. The longitudinal length of the mattress 9 can be adjusted by the number of cushion C units connected.

[0031] The longitudinal connection of the three cushions C1 to C3 can be explained using the connection between cushion C1 and cushion C2 as an example. As shown in Figure 3, on the sides 31a and 31b of the longitudinally adjacent mattresses C1 and C2, the male fastener 412a at the end of the belt material 411a of the first connecting member 41a of cushion C1 is connected to the female fastener, which is the second connecting member 42b of cushion C2. At the same time, the male fastener 412b at the end of the belt material 411b of the first connecting member 41b of cushion C2 is connected to the female fastener, which is the second connecting member 42a of cushion C1.

[0032] Since adjacent cushions are connected at two points along the thickness direction of their sides, the connection strength of the cushions is improved compared to conventional methods, and slippage at the connection points is reliably suppressed. Furthermore, because the connection is made with hook-and-loop fasteners, the cushion connection process becomes even simpler.

[0033] As shown in Figure 4, in cushion C, the free end of the belt material 411 of the first connecting member 41, which is not used to connect to other cushions, is connected to the female fastener, which is the third connecting member 43, attached to the side surfaces 33 and 34 of the cushion, by connecting the male fastener 412 of the belt material 411 to the female fastener. This effectively prevents the belt material 411 of the first connecting member 41 from flapping unnecessarily, and also improves the appearance of cushion C.

[0034] In this way, multiple cushions C1 to C3 can be connected and separated along their length. For example, when used as a mattress 9, the length of the mattress 9 can be adjusted as needed to suit the user's height and growth. Furthermore, when storing, the individual cushions C1 to C3 can be separated and stored separately.

[0035] The cushions according to the present invention can be connected not only in the longitudinal direction but also in the width direction. Figure 5 illustrates the connection state of the connectors at the center of the four cushions C1 to C4 in a plan view when two cushions C1 to C4 are connected in the longitudinal direction and two in the width direction.

[0036] The belt material 411a of the first connecting member 41a of cushion C1 is bent approximately perpendicularly outward with respect to the side surface 31a, and the male fastener 412a at the tip of the belt material 411a is connected to the female fastener 43d, which serves as the third connecting member of cushion C4.

[0037] The belt material 411b of the first connecting member 41b of cushion C2 is bent approximately perpendicularly outward with respect to the side surface 31b, and the male fastener 412b at the tip of the belt material 411b is connected to the female fastener 43c, which serves as the third connecting member of cushion C3.

[0038] The belt material 411c of the first connecting member 41c of cushion C3 is bent approximately perpendicularly outward with respect to the side surface 32c, and the male fastener 412c at the tip of the belt material 411c is connected to the female fastener 43b, which serves as the third connecting member of cushion C2.

[0039] The belt material 411d of the first connecting member 41d of cushion C4 is bent approximately perpendicularly outward with respect to the side surface 32d, and the male fastener 412d at the tip of the belt material 411d is connected to the female fastener 43a, which serves as the third connecting member of cushion C1.

[0040] In this way, cushions C1 and C4, and cushions C2 and C3, which are located diagonally opposite each other, are connected, and as a result, the four cushions C1 to C4 are fixed together as a whole.

[0041] By performing similar connections, it becomes possible to fix a desired number of cushions in the longitudinal and width directions to form an assembly. As shown in Figure 4, the free end of the belt material 411 of the first connecting member 41, which is not used to connect to other cushions, is connected to the female fastener 412 of the third connecting member 43 of the cushion by connecting the male fastener 412 of the belt material 411 to the female fastener. This effectively prevents the belt material 411 of the first connecting member 41 from flapping unnecessarily and also improves the appearance of the cushion material.

[0042] (others) In the embodiments described above, the shape of the cover was rectangular (square) in plan view, but the present invention is not limited to this and may be a polygon such as a pentagon or hexagon.

[0043] Furthermore, the connection points are not limited to two locations in the thickness direction; there may be three or more locations, taking into account the thickness of the cushion. [Industrial applicability]

[0044] According to the cover of the present invention, the process of connecting cushions becomes even simpler, and the connection strength can be further improved. [Explanation of Symbols]
