In addition to toilets and tankers, medicines, drinking water, emergency food, and the like are examples of disaster-prevention-related goods that are desired to be stockpiled. However, in the event of a disaster, it is assumed that many people will sit or sleep directly on the floor of the evacuation site. will be amplified. Due to these circumstances, there is a demand for a stockpile of cushioned mats that allow people to lie down or sit down to rest. It was difficult to secure a storage space due to its bulkiness.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mat storage structure and a mat storage bench capable of storing a plurality of mats.

The mat storage structure of the present invention includes a cushion main body having cushioning properties, which is configured by laminating a plurality of mats having cushioning properties, and fixing means for fixing the mats to maintain the laminated state. .

According to this configuration, the cushion body of the structure that is normally used as a bench or the like is composed of a plurality of mats that can be used, for example, in the event of a disaster. It is possible to stockpile. The plurality of mats that make up the main body of the cushion, for example, are normally stacked and used as a seat surface on which people sit, such as a bench, so they are not bulky and can be taken out sequentially in the event of a disaster or the like. In addition, it is placed on the floor or the like so that a person can use it by lying down.

Moreover, even if a person normally rides on the structure and puts his/her weight on the cushion main body, the fixing means fixes the mats and maintains the laminated state of the mats, so that the laminated state does not collapse easily.

Further, the fixing means may have an erecting portion erected upward from the upper surface of the cushion body.

According to such a configuration, for example, the standing portion of the fixing means can be used as an armrest or backrest of a chair, a handrail of a bed, or the like.

Furthermore, the structure may include a cover that covers the cushion body.

According to such a configuration, since the laminated mat is covered with the cover, the laminated mat does not appear in the appearance of the structure at normal times, so that the appearance of the structure is improved.

The mat storage structure may be a mat storage bench, wherein the upper surface of the cushion body is a seat surface.

With such a configuration, the mat storage structure can be used as a bench.

As described above, according to the present invention, it is possible to provide a mat storage structure and a mat storage bench capable of storing a plurality of mats.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3(b). As shown in FIG. 1, a structure 1, which is a mat storage structure, includes a cushion body 2 having cushioning properties, and fixing means 4 for fixing mats 3 to maintain a stacked state. The cushion main body 2 is constructed by laminating a plurality of mats 3 as shown in FIGS. 2 and 3(a). Moreover, the structure 1 of this embodiment is a mat storage bench. In this specification, a bench is a concept including chairs, couches, sofas, and the like.

The mat 3 constitutes the cushion main body 2 in a laminated state, is a mat having cushioning properties, and maintains its shape even when laminated. Also, the mat 3 can be laid alone on a floor or the like and used. The materials and shapes of the mats 3 included in the cushion body 2 of the present embodiment may be different, but are preferably the same. Mat 3 is, for example, a foam sheet. The material of the mat 3 is preferably a soft resin such as polyvinyl chloride, urethane, olefin, acrylic, styrene, polyethylene, polyvinyl acetate, and rubber. Polyvinyl chloride is preferred.

The shape of the mat 3 is, for example, a long plate shape, as shown in FIG. 3(b). Specifically, the shape of the mat 3 when viewed in the thickness direction is a rectangular shape with missing four corners, that is, a rectangular shape with recesses 30 provided at the four corners for fixing to the fixing means 4 . The thickness direction of the mat 3 is the vertical direction when the mat 3 is laid on the floor and used, that is, the vertical direction of the paper surface of FIG. 3(b). All four recesses 30 have the same shape. The recessed portion 30 is recessed inward in the surface direction of the mat 3 , that is, recessed so as to approach the center of the mat 3 in the surface direction. The angle of the recess 30 is, for example, a right angle. The recess 30 is defined by a recess first outer edge 31 extending in the longitudinal direction of the mat 3 and a recess second outer edge 32 extending in the lateral direction of the mat 3 .

In the mat 3 of this embodiment, the thickness of any part is uniform. The thickness of the mat 3 is, for example, 2.0 mm or more and 100 mm or less, preferably 3.0 mm or more and 50 mm or less, and more preferably 4.0 mm or more and 10 mm or less. If the thickness of the mat 3 is at least the lower limit value, it is possible to ensure cushioning properties and strength. Mats 3 can be stockpiled.

If the mat 3 has such a thickness, the number of laminated mats 3 in the cushion body 2 is preferably 4 or more and 200 or less, and preferably 50 or more and 90 or less. When the number of laminated mats 3 having such a thickness is 50 or more and 90 or less, the height of the seat surface 21 of the cushion main body 2 becomes an appropriate height of, for example, 300 mm or more and 400 mm or less from the floor.

The dimension of the mat 3 in the lateral direction is preferably 500 mm or more and 1500 mm or less, and more preferably 600 mm or more and 1200 mm or less. The longitudinal dimension of the mat 3 is preferably 1600 mm or more and 2400 mm or less, and more preferably 1800 mm or more and 2000 mm or less. If the dimension of the mat 3 in the lateral direction is equal to or greater than the lower limit, the depth dimension of the cushion body 2 can be ensured when used as a bench. If the dimension in the longitudinal direction of the mat 3 is equal to or larger than the lower limit value, an area for a person to sit or lie down can be secured, and if it is equal to or smaller than the upper limit value, a space for accommodating the mat 3 can be secured without being too large. easier.

For example, the mat 3 is manufactured by Toli Co., Ltd. under the product name "underlay sheet" with a thickness of 6 mm. The underlay sheet is a product that is installed under vinyl floor sheets and used to reduce the impact of falls. have sex.

The cushion main body 2 is a block having cushioning properties on which a person can ride (see FIGS. 2 and 3(a)). The cushion body 2 of this embodiment is directly installed on the floor. Further, in the cushion main body 2 of the present embodiment, the stacking direction of the mats 3 is one direction. Specifically, the stacking direction of the mats 3 is the vertical direction, that is, the vertical direction, for example, the height direction of the bench. In addition, in the cushion main body 2 of the present embodiment, the mats 3 are laminated in an unfolded state, that is, in an unfolded state.

Furthermore, the shape of the cushion main body 2 of this embodiment is, for example, a substantially rectangular parallelepiped shape. Specifically, the shape of the cushion main body 2 is a rectangular parallelepiped shape with four corners missing, for example, a rectangular parallelepiped shape with concave portions 20 provided at the four corners (see FIG. 2). All four recesses 20 have the same shape. The recessed portion 20 is recessed inward in the surface direction of the seat surface 21 and the lower surface 22 of the cushion body 2, for example, recessed so as to approach the center of the seat surface 21 and the lower surface 22 in the surface direction. The recess angle of the recess 20 is, for example, a right angle.

In addition, the cushion body 2 of the present embodiment is the upper surface on which a person can ride, and faces the seat surface 21, which is the upper surface of the mat 3 positioned highest among the laminated mats 3, and the seat surface 21. and a lower surface 22 which is the lower surface of the mat 3 placed on the floor and located at the lowest position among the laminated mats 3 . In addition, the cushion body 2 connects the side surfaces of the laminated mats 3, that is, the outer peripheral surfaces, for example, a pair of long wall surfaces 23, a pair of short wall surfaces 24, and the adjacent long wall surface 23 and short wall surface 24, and It has a recess first surface 25 and a recess second surface 26 that define the recess 20 . The recessed first surface 25 extends along the longitudinal direction of the mat 3 , for example, the longitudinal direction of the mat 3 , that is, the longitudinal direction of the seat surface 21 and the lower surface 22 of the cushion body 2 . The recessed second surface 26 extends along the widthwise direction of the mat 3 , ie, the widthwise direction of the seat surface 21 and the bottom surface 22 of the cushion body 2 .

A fixing means 4 is detachably attached to the cushion body 2 of this embodiment. The cushion body 2 has, for example, a shape corresponding to that of the fixing means 4, and at least a portion of the cushion body 2 contacts the fixing means 4 in the longitudinal direction and the lateral direction of the mat 3, thereby restricting the movement of the mat 3 in the plane direction. It has a regulated portion 200 to be controlled. It should be noted that the restricted portion 200 only needs to restrict the movement of the mat 3 in the planar direction by coming into contact with the fixing means 4 in the planar direction of the mat 3 . The shape of the portion facing the regulated portion 200 is more effective in regulating the movement of the mat in the plane direction as the number of matching portions increases.

The regulated portion 200 of the cushion body 2 includes, for example, a pair of longitudinally regulated portions 24 and 26 aligned at both ends of the mat 3 in the longitudinal direction and abutting against the fixing means 4 in a direction along the longitudinal direction of the mat 3, A pair of laterally regulated portions 25 are arranged at both ends of the mat 3 in the lateral direction and abut against the fixing means 4 in a direction along the lateral direction of the mat 3 . For example, the longitudinal restricted portions 24 and 26 have a shape corresponding to the portion facing the longitudinal restricted portions 24 and 26 of the fixing means 4 , and the lateral restricted portion 25 has a shape corresponding to that of the fixing means 4 . It has a shape corresponding to the portion facing the lateral direction restricted portion 25 of . The shape of the regulated portion 25 in the lateral direction corresponds to the portion of the fixing means 4 facing the regulated portion 25 in the lateral direction. Although it is highly effective, it is not always necessary to match all of them, and even if the corresponding parts are only a part, it can be regulated. The same applies to the longitudinal restricted portions 24 and 26 .

The longitudinally regulated portions 24 and 26 are portions to which longitudinal regulating portions 432 and 440, which will be described later, come into contact from the sides to regulate the position of the mat 3 and suppress displacement in the longitudinal direction. In the cushion body 2 of the present embodiment, the pair of short wall surfaces 24 and the pair of recessed second surfaces 26 arranged in the longitudinal direction of the cushion body 2 are the pair of longitudinally regulated portions 26 .

The lateral direction regulated portion 25 refers to a portion that restricts the position of the mat 3 and suppresses displacement in the lateral direction by a lateral direction regulating portion 431 (to be described later) abutting from the side. In the cushion main body 2 of the present embodiment, the pair of concave first surfaces 25 aligned in the transverse direction of the cushion main body 2 are the pair of transverse direction restricted portions 25 .

The fixing means 4 is detachably attached to the cushion body 2 . In addition, the fixing means 4 fixes the mat 3 so that the laminated state of the mat 3 does not collapse when attached to the cushion main body 2, and for example, restricts the positional deviation of the mat 3 in the plane direction. The fixing means 4 of this embodiment fixes the mats 3 and maintains the stacking state of the mats 3, but it is not necessary to fix all the mats 3 completely. In the fixing means 4, for example, the fixing member 40 and the mat 3 are not in contact with each other in a normal state, but the fixing member 40 and the mat 3 are brought into contact with each other only when the mat 3 is displaced and the laminated state of the mat 3 is about to collapse. It also includes a configuration in which the position of the mat 3 is regulated to such an extent that the stacking state of the mat 3 is not collapsed, such as a configuration in which the stacking state is maintained. The surface direction of the mat 3 includes at least one of the longitudinal direction of the mat 3 and the lateral direction of the mat 3, for example. The fixing means 4 of the present embodiment includes a pair of fixing members 40 provided to sandwich the cushion body 2 in the horizontal direction, and a fixing cover 5 covering at least the cushion body 2 .

The fixing member 40 of this embodiment is attached to the cushion body 2 via the fixing cover 5 . Specifically, the fixing member 40 has a fastener as a fixing member attaching/detaching portion 49 that can be attached to and detached from the fixing cover 5 . Fasteners include point fasteners, line fasteners, and hook-and-loop fasteners, but in this embodiment, an example using a line fastener will be described. The fixing member attachment/detachment part 49 is arranged, for example, at least part of the outer edge of the surface of the fixing member 40 facing the short wall surface 24 of the cushion body 2 . are placed in The hook-and-loop fastener is particularly suitable for the present invention because it has the characteristic that the fixing member 40 and the fixing member attachment/detachment portion 49 can be joined together in a flat state without a gap, without being easily separated from each other with a simple operation.

A pair of fixing members 40 are provided so as to sandwich the cushion body 2 in the longitudinal direction of the mat 3 . The shape of the pair of fixing members 40 is the same. The shape of the pair of fixing members 40 may be different, for example, asymmetrical. In addition, the fixing member 40 of the present embodiment extends upward from a surface including the fixing portion 41 for fixing the laminated state of the mats 3 together and the seat surface 21 which is the upper surface of the cushion main body 2, that is, is erected. It has at least one of the upright portions 42 . Specifically, the fixing means 4 has such a fixing portion 41 and an armrest portion 42 functioning as an armrest on a bench as a standing portion 42 .

The shape of the fixing portion 41 is a shape corresponding to the shape of the cushion main body 2, and is, for example, a substantially rectangular plate shape. The height of the fixing portion 41 of this embodiment is substantially the same as the height of the cushion body 2 . In addition, the fixing portion 41 of the present embodiment includes a rectangular plate-shaped body portion 44 and a pair of portions extending in the thickness direction of the body portion 44 from both ends of the main surface 440 of the body portion 44 and arranged at intervals from each other. and a convex portion 43 of

The projection amount of the projection 43 from the main surface 440 of the main body portion 44 is approximately the same size as the recess of the recess 20 of the cushion body 2 . Further, the convex portion 43 extends over the entire height direction of the cushion body 2 . The dimension in the direction perpendicular to the thickness direction and the height direction of the main body part 44, specifically, the dimension of the interval in the direction in which the pair of protrusions 43 of the main body part 44 are arranged, is the width of the short wall surface 24 of the cushion body 2. It is substantially the same as the dimension in the lateral direction. The angle of the portion of the projection 43 facing the recess 20 is, for example, a right angle. The outer peripheral surface of the protrusion 43 includes a protrusion first surface 431 extending in the longitudinal direction of the mat 3 and a protrusion second surface 432 extending in the width direction of the mat 3 .

Since each fixing portion 41 of the present embodiment has a pair of protrusions 43 arranged in the width direction of the mat 3, a pair of protrusion first surfaces 431 exist so as to sandwich the cushion body 2 in the width direction of the mat 3. (see Figure 2). In addition, since a pair of fixing portions 41 are arranged so as to sandwich the cushion body 2 in the longitudinal direction of the mat 3 , a pair of projection second surfaces 432 are present with the cushion body 2 sandwiched therebetween.

The fixed portion 41 has a restricting portion 400 that restricts movement of the mat 3 in the plane direction by contacting the restricted portion 200 of the cushion body 2 . The restricting portion 400 of the fixing portion 41 of the present embodiment restricts the movement of the plurality of mats 3 constituting the cushion main body 2 in the planar direction, thereby suppressing the displacement of the cushion main body 2 . The restricting portion 400 has a longitudinal restricting portion 432 that restricts the positional displacement of the mat 3 in the longitudinal direction, and a transverse restricting portion 431 that suppresses the positional displacement of the mat 3 in the lateral direction.

In this embodiment, the longitudinal direction restricting portions 432 are a pair of convex second surfaces 432 arranged to sandwich the cushion body 2 in the longitudinal direction of the mat 3 . The lateral direction restricting portions 431 are a pair of convex first surfaces 431 arranged to sandwich the cushion body 2 in the lateral direction of the mat 3 .

The armrest portion 42 includes an extension portion 45 extending upward from the fixed portion 41 and an armrest portion 46 arranged on the extension portion 45 . The armrest portion 42 of the present embodiment is provided with a pair of extension portions 45 , and each of the pair of extension portions 45 extends upward from an upper surface 441 that is continuous with the main surface 440 of the main body portion 44 . The main surface 440 also functions as a longitudinal direction restricting portion 440 by coming into contact with both ends of the mat 3 in the longitudinal direction. In addition, the upper surface 441 of this embodiment is positioned on a surface including the seat surface 21 of the cushion body 2 . All of the extending portions 45 are shaped like a round bar. The shape of the extension portion 45 may be a shape other than a round bar, such as a square bar. The shape of the armrest portion 46 is a rectangular plate shape with rounded corners. Both ends of the armrest portion 46 in the longitudinal direction are supported by a pair of extending portions 45 . The material of the fixing part 41 and the armrest part 42 of the present embodiment is, for example, hard resin, wood, metal, etc., but it is durable, water resistant, and has a high degree of freedom in shape. Resin is preferred. The fixing portion 41 and the armrest portion 42 may be made of the same material or may be made of different materials.

The fixed cover 5 covers the cushion body 2 to hide the layered state of the mats 3 to improve the design, and also protects the mats 3 to prevent staining. The material of the fixed cover 5 of the present embodiment is, for example, soft resin such as polyvinyl chloride or polyurethane, cloth, leather, or the like. By using such a flexible material, a plurality of mats 3 can be integrated to function as the cushion main body 2 without impairing the cushioning properties of the mats 3, and the feeling of touch is excellent. In addition, the fixed cover 5 of the present embodiment has a fastener as a cover attaching/detaching portion 50 that can be attached/detached to/from the fixing portion 41 . The cover attachment/detachment part 50 is arranged, for example, at least part of the outer edge of the fixed cover 5, and specifically, is arranged at the upper edge and the side edge of the outer edge.

In addition, the fixed cover 5 covers at least a part of the outer peripheral surface of the cushion body 2, for example, at least three surfaces of the rectangular parallelepiped cushion body 2, and specifically, the seat surface 21 of the cushion body 2 and the cushion body 2. of the side surfaces of , which are not surrounded by the fixing portion 41 are covered. The fixed cover 5 also covers the seat surface 21 and the long wall surface 23 of the cushion body 2 . The fixed cover 5 of this embodiment has a seat surface covering portion 51 that covers the seat surface 21 of the cushion body 2 and a side surface covering portion 52 that covers the side surface of the cushion body 2, for example, the long wall surface 23. As shown in FIG. Furthermore, the fixed cover 5 has a function of fixing the mat 3 to maintain the stacking state in addition to the function described above. The shape of the fixed cover 5 of this embodiment corresponds to the shape of the cushion body 2 .

With such a configuration, the projections 43 of the fixing member 40 are fitted into the recesses 20 of the cushion body 2 in a normal state, that is, when the fixing member 40 is attached to the cushion body 2 via the fixing cover 5 . , the fixing member 40 maintains the stacked state of the mats 3 . At this time, the thickness direction of the body portion 44 coincides with the longitudinal direction of the mat 3 . The longitudinal regulating portion 432 of the fixing member 40 abuts on the entire lengthwise regulated portion 26 of the cushion body 2 in the height direction, thereby regulating the positional displacement of the entire stack of mats 3 in the longitudinal direction. . The lateral direction restricting portion 431 abuts on the entire height direction of the lateral direction restricted portion 25 of the cushion body 2 , thereby restricting the displacement of the entire stack of mats 3 in the lateral direction.

In the structure 1 of the present embodiment, for example, the cushion main body 2 is formed by laminating the mats 3, and after covering the cushion main body 2 with the fixed cover 5, the fixing member is attached to the cushion main body 2 covered with the fixed cover 5. It is assembled by attaching 40. The mats 3 laminated in this way normally function as a part of the bench on which a person sits. When attaching the fixing member 40 to the cushion main body 2 of the present embodiment, the pair of fixing members 40 sandwich the cushion main body 2 covered with the fixing cover 5 from both sides in the longitudinal direction of the cushion main body 2. , the cover attachment/detachment portion 50 is attached to the fixing member attachment/detachment portion 49 . Thereby, the cushion main body 2 is integrated with the pair of fixing members 40 and the fixing cover 5 .

On the other hand, in the structure 1 of the present embodiment, for example, by removing the fixing member 40 and the fixing cover 5 from the cushion body 2, the mats 3 constituting the cushion body 2 can be sequentially taken out and used. Each mat 3 taken out in this way functions as a mat on which a person sits or lies down in the event of a disaster or the like. When removing the fixing member 40 from the cushion main body 2 of this embodiment, the cover attaching/detaching portion 50 and the fixing member attaching/detaching portion 49 are removed, and the pair of fixing members 40 are separated in the longitudinal direction of the cushion main body 2. The fixing cover 5 is removed from the cushion main body 2 after removing it from the cushion main body 2 covered with the fixing cover 5 by pulling it out from both sides.

The structure 1 is installed and used in facilities such as airports, stations, and shopping centers, indoor facilities such as residences, outdoor facilities such as parks, transportation means such as vehicles and ships, and the like. Not only at the time of disaster but also at the time of holding an event where a large number of people gather, the user can take a rest on the mat 3 by taking out the mat 3 from the inside of the fixed cover 5 and laying it on the floor surface or the like.

According to the structure 1 described above, the cushion body 2 of the structure 1, which is normally used as a bench or the like, is composed of a plurality of mats 3 that can be used, for example, in the event of a disaster. The object 1 can store a plurality of mats 3. Specifically, since the structure 1 serves as both furniture such as benches that people usually ride on and a device for stockpiling the mats 3, a plurality of mats 3 are provided in addition to the space for placing the structure 1. There is no need to separately provide a space for stockpiling. Incidentally, the plurality of mats 3 constituting the cushion body 2 are, for example, normally stacked and used as a seating surface, such as a bench, on which people sit, and are taken out one after another in the event of a disaster or the like. It is placed on the floor so that a person can use it by lying down.

According to the structure 1 of this embodiment, since the fixing means 4 fixes the mat 3 and maintains the laminated state, even if a person normally rides on the structure 1 and puts his or her weight on the cushion main body 2, , the laminated state of the mat 3 is not disturbed. Moreover, since the fixing means 4 regulates the positional deviation of the mat 3 in the surface direction, it is possible to reliably prevent the stacking state of the mat 3 from collapsing. Specifically, since the fixing portion 41 of the present embodiment has the lateral direction restricting portion 431, positional deviation of the cushion body 2 in the lateral direction can be restricted. In addition, since the fixing portion 41 of the present embodiment has the longitudinal direction restricting portion 432, it is possible to restrict the displacement of the cushion body 2 in the longitudinal direction. In order for the fixing means 4 to fix the mats and maintain the laminated state, it is not always necessary to always contact the fixing means 4, and when the position of the mat 3 deviates more than a certain amount, the fixing means 4 contacts and regulates. It can be like this.

Furthermore, since the fixing portion 41 fixes the laminated state of the mats 3 collectively, the operation of attaching the pair of fixing portions 41 to the mat 3 can be completed in one operation. Deviation can be regulated.

In addition, a pair of fixing portions 41 are provided so as to sandwich the cushion main body 2 in the horizontal direction when attached to the cushion main body 2 . Therefore, when the fixing part 41 is attached to the cushion body 2, the cushion body 2 placed on the floor is sandwiched by the pair of fixing parts 41 from both sides, for example, from both sides in the longitudinal direction of the cushion body 2. 41 and the cushion main body 2 can be positioned and attached easily.

Further, according to the structure 1 of the present embodiment, since the fixing means 4 includes the standing portion 42 erected from the surface including the seat surface 21 of the cushion body 2, the standing portion 42 of the fixing means 4 can be placed on the bench. can be used as an armrest or the like. In this way, the erected portion 42 also serves as a member constituting a part of existing furniture, for example, a bench, so that it can be used as an armrest for the structure 1, thereby separately maintaining the stacked state of the mats 3. Since there is no need to provide such a member, the number of parts can be suppressed. In addition, even if the erected portion 42 is provided, the appearance of the structure 1 becomes close to that of an existing bench, and it can be used normally without a sense of discomfort.

Furthermore, according to the structure 1 of the present embodiment, since the laminated mats 3 are covered with the fixed cover 5, the laminated mats 3 do not appear in the appearance of the structure 1 at normal times. Therefore, the appearance of the structure 1 is similar to that of existing benches.

Moreover, according to the structure 1 of the present embodiment, since the stacking direction of the mats 3 is the vertical direction, the stacking direction of the mats 3 coincides with the direction in which the weight of the mats 3 is applied when there is no person on the floor. Therefore, the laminated state of the mat 3 is likely to be maintained. Similarly, even when a person gets on the structure 1, since the vertical direction in which the weight is applied to the mat 3 and the stacking direction of the mat 3 match, the stacking state of the mat 3 is likely to be maintained. .

It should be noted that the structure of the present invention is not limited to the above-described embodiment, and of course various modifications can be made without departing from the gist of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, some of the configurations of certain embodiments can be deleted.

For example, although the structure 1 is a bench, it may be a piece of furniture other than a bench, such as a chair for one person such as a stool, or a bed, which includes a portion having cushioning properties on which a person sits. Further, the structure 1 may be a floor of a kids' corner having a cushioning property for children to play with, or a partition or the like that is one step higher than the floor. For example, when the structure 1 is a kids' corner including a floor and partitions, by varying the number of laminated mats 3 constituting the cushion body 2 in the area corresponding to the floor of the kids' corner and the area corresponding to the partition. , the height of the cushion body 2 in each region can be varied. As a result, normally, the lower area of the cushion body 2 can be used as the floor of the kids' corner, and the higher area of the cushion body 2 can be used as the partition of the kids' corner. However, among application examples, the bench is most preferable because it is highly convenient during normal use and the size of the mat is easy to use.

In the above-described embodiment, the structure 1 is a bench, and the standing portion 42 of the fixing means 4 also serves as an armrest. You can also serve as one. For example, when the structure 1 is a bed, the standing portion 42 may serve as at least one of a handrail and a headboard. Utilizing the standing portion 42 as a handrail or a headboard has the effect of enhancing convenience with a small number of members.

In the above-described embodiment, the projection first surface 431, the projection second surface 432, and the main surface 440 of the fixing means 4, that is, the entire surface of the fixing means 4 facing the cushion body 2, are attached to the cushion body 2. Although they are in contact with each other, at least a part of them may be separated from the cushion main body 2 . In this case as well, if the surface of the fixing means 4 facing the cushion main body 2 extends in the lateral direction or the longitudinal direction of the cushion main body 2, the movement of the cushion main body 2 can be restricted, so that it functions as the restricting portion 400. . Further, the longitudinal direction restricting portion 432 of the fixing means 4 extends substantially parallel to the longitudinal restricted portion 26 in the lateral direction of the cushion body 2, but it may extend along the lateral direction. It may extend obliquely along the width direction, or may extend curvedly along the width direction. Although the lateral direction restricting portion 431 extends substantially parallel to the lateral direction restricted portion 25 in the longitudinal direction of the cushion body 2, it may extend along the longitudinal direction. The movement of the cushion main body 2 can be restricted even if it extends in the direction or is curved along the longitudinal direction, so it functions as the restricting portion 400 .

Furthermore, although the fixing member 40 includes the fixing portion 41 and the standing portion 42, one of these may not be included. For example, as shown in FIG. 4A, the fixing member 40 may have a binding portion 47 that binds and fixes the laminated state of a plurality of mats 3 among the laminated mats 3 . In the figure, the binding portion 47 is fixed by binding the mats 3 together in a laminated state, and specifically, may be a rubber band. It is conceivable that the binding portion 47 regulates the movement of the mat 3 in the planar direction and also regulates the movement of the mat 3 in the thickness direction. Three are arranged so that the both ends 27 and the central part 28 may be lashed, respectively.

The binding part 47 may be a string instead of a rubber band. In this case, the string binds the cushion main body 2, and the bound cushion main body 2 is placed on a board or the like and a tucker is used. It is conceivable to fasten the pry string and the plate. Even with such a fixing member 40, it is possible to maintain the stacking state of the mats 3 and to restrict the positional deviation of the mats 3 at least in the surface direction. can.

The structure 1 may also include a frame-shaped or box-shaped fixing portion 41 surrounding at least a portion of the cushion main body 2 fixed by the binding portion 47. In the figure, the fixing portion 41 is the cushion It has a box-like shape that accommodates substantially the lower half of the main body 2 . If the fixing portion 41 is a frame that surrounds the entire outer circumference of the cushion body 2 in the stacking direction, the mats 3 can be fixed collectively and the stacking state of the mats 3 can be maintained collectively.

Furthermore, in the figure, the fixing portion 41 includes a fixing member attachment/detachment portion 49 provided at the upper end, a pair of long wall surfaces 410 that sandwich the cushion body 2 in the width direction of the cushion body 2 as width direction regulation portions 410, A pair of short wall surfaces 411 sandwiching the cushion body 2 in the longitudinal direction of the cushion body 2 is provided as the longitudinal direction regulation part 411 . The regulated portion 200 of the cushion body 2 is the side surface of the cushion body 2, such as the long wall surface 23 or the short wall surface 24. As shown in FIG. It is conceivable that the shape of the mat 3 when viewed from the thickness direction is rectangular as shown in FIG. 4(b).

At this time, as shown in FIG. 5, the fixed cover 5 may cover the portion of the cushion main body 2 that is not accommodated in the fixed portion 41, that is, the substantially upper half of the cushion main body 2. As shown in FIG. In addition, the fixed cover 5 has a cover attachment/detachment portion 50 provided at the lower end in the figure.

In this structure 1, when the fixing means 4 is attached to the cushion main body 2, the laminated mats 3 are fixed by the binding portion 47, and substantially the lower half of the cushion main body 2 is accommodated in the fixing portion 41, while the cushion main body 2 is covered with a fixed cover 5, and the fixed cover 5 is attached to the fixed part 41 (see FIGS. 4A and 5).

In addition to the above configuration, the fixing means 4 has a fixing portion 41 that penetrates the cushion body 2 in the thickness direction of the mat 3 at at least one location, as shown in FIGS. 6(a) to 7(b). You may At this time, the fixing portion 41 passes through the stacked mats 3 to function as a penetration restricting portion 401 that restricts positional displacement of the mats 3 in the longitudinal direction and the lateral direction.

Specifically, the fixing means 4 includes a fixing portion 41 that penetrates at least a plurality of the stacked mats 3, for example, the entire mat 3 to maintain the stacked state of the mats 3, and an extension extending upward from the fixing portion 41. It is contemplated to have an upright portion 42 including a portion 45 and an armrest portion 46 . The shape of the fixed part 41 is, for example, a bar shape, and in the figure, it is a round bar shape. The dimension of the fixed portion 41 in the longitudinal direction is approximately the same as the height of the cushion body 2 .

It is conceivable that the four corners of the cushion main body 2 are provided with through holes 29 through which the fixing portions 41 are inserted and penetrated in the thickness direction of the mat 3 . The through-hole 29 has a shape corresponding to that of the fixing portion 41, and is a round hole corresponding to the shape of a round bar in FIG. If the through-hole 29 has a shape corresponding to that of the fixing portion 41 in this manner, the range in which the mat 3 can move is reduced, so that the effect of regulating the cushion body 2 is enhanced. A surface defining the through-hole 29 functions as a penetration-restricted portion 201 (see FIG. 7). At this time, the shape of the mat 3 when viewed from the thickness direction is rectangular. Further, at the four corners of the mat 3, as shown in FIG. 8A, through-holes 33 are provided through which the fixing portions 41 are inserted and penetrate the mat 3 in the thickness direction. The fixing portion 41 penetrating through the laminated mats 3 may have a plate-like shape, for example, a plate-like shape extending in the width direction of the mats 3 . In this case, it is conceivable that the through-hole of the mat 3 through which the fixing portion 41 is inserted is an elongated rectangular through-hole in which the two through-holes 33 are communicated in the lateral direction of the mat 3 .

When the fixed portion 41 is rod-shaped, for example, a round rod-shaped fixed cover 5, the fixed cover 5 may cover the cushion body 2 and expose the standing portions 42 through through holes 53 provided at the four corners (see FIG. 6 ( a) see). Even with such a fixing means 4, the stacking state of the mats 3 is maintained, and among the positional deviations in the surface direction of the mats 3, the positional deviations other than the positional deviations in the rotational direction, for example, the positional deviations in the longitudinal direction of the mats 3 are prevented. and positional deviation in the lateral direction can be regulated.

The fixing portion 41 that penetrates the cushion main body 2 in the thickness direction of the mat 3 may be one. Both misalignment in direction can be constrained.

Furthermore, the structure 1 may include a plate member 6 attached to a surface other than the seat surface 21 of the cushion body 2, for example, a side surface including a pair of long wall surfaces 23 and a pair of short wall surfaces 24 and a lower surface 22. In FIG. 6(b), an elongated plate member 6 is provided as a plate member attached to the lower surface 22 of the cushion body 2, and the cushion body 2 is placed on the floor via the plate member 6. In FIG. The plate member 6 may be, for example, a plate made of resin. In this case, the plate member 6 is arranged at the upper end of the outer peripheral edge of the plate member 6 and is detachable from the cover attachment/detachment portion 50 of the fixed cover 5. It is conceivable to have a plate member attachment/detachment portion 60 (see FIG. 6(a)). The plate member attachment/detachment part 60 may be, for example, a fastener, and is a line fastener in the figure.

In this case, the fixed portion 41 may penetrate the plate member 6 in the thickness direction in addition to the cushion body 2 . Further, in FIG. 8B, the plate member 6 is also provided with a through hole 61 through which the fixing portion 41 is inserted and penetrated in the thickness direction of the plate member 6 . A plate member 6 may be attached to the side surface of the cushion body 2 and extended to a position higher than the seat surface 21 of the cushion body 2, so that the plate member 6 may be used as a backrest of a bench. .

With such a configuration, the fixing portion 41 can regulate not only the positional deviation of the mat 3 in the longitudinal direction and the lateral direction, but also the positional deviation of the mat 3 and the plate member 6 in the longitudinal direction and the lateral direction. . In addition, in this structure 1, when the fixing means 4 is attached to the cushion body 2, the mat 3 is laminated on the plate member 6, and the laminated mat 3 is covered with the fixed cover 5. After the fixed portion 41 is passed through the covered through hole 29 of the cushion main body 2 , the through hole 61 of the plate member 6 , and the through hole 53 of the fixed cover 5 , the plate member attaching/detaching portion 60 is attached to the cover attaching/detaching portion 50 . can be considered to be installed.

As shown in FIGS. 9(a) to 10(b), the fixing portion 41 of the fixing means 4 maintains the laminated state of the mat 3 by inserting both end portions 27 in the longitudinal direction of the cushion body 2. It may have a locking recess 48 . By arranging the fixing means 4 so as to sandwich the cushion body 2 in the longitudinal direction of the cushion body 2, it is conceivable that a pair of fixing recesses 48 are arranged so as to sandwich the cushion body 2 in the longitudinal direction. In the same figure, the fixing recess 48 extends in the vertical direction and faces the long wall surface 23 of the cushion body 2 , which is a first vertical surface 481 that is a lateral direction restricting portion 481 , 24, and a horizontal surface 483 extending horizontally as a thickness-direction restricting portion and sandwiching the end portion 27 of the cushion body 2 in the height direction.

In this case, the fixing means 4 has, in addition to the fixing portion 41, an upright portion 42 composed of an extension portion 45 and an armrest portion 46 integrally formed, and the shape of the upright portion 42 is that of the upper surface. It is conceivable to use a curved plate shape to make it easier to place a hand on the surface. Even with such fixing means 4, it is possible to maintain the laminated state of the mats 3 and to regulate the positional deviation of the mats 3 at least in the planar direction. The lateral direction restricting portion 481 can restrict positional displacement of the mat 3 in the lateral direction. In addition, a pair of longitudinal direction restricting portions 482 arranged on both sides of the cushion body 2 in the longitudinal direction of the cushion body 2 can restrict positional displacement of the mat 3 in the longitudinal direction. Furthermore, the pair of horizontal surfaces 483 that partition one fixed recess 48 can also restrict the positional deviation of the mat 3 in the thickness direction.

In this case, the laminated mats 3 are placed on a plate member 6 as shown in FIG. Something is possible. In this case, both ends 62 of the plate member 6 in the longitudinal direction are inserted into the fixing recesses 48 of the fixing portion 41 together with the opposite ends 27 of the laminated mat 3 , that is, the cushion main body 2 . When the rigidity of the material of the plate member 6 is higher than the rigidity of the material of the mat 3, the cushion body 2 is less likely to deform due to its own weight or the load when a person sits on it.

In this structure 1, when the fixing means 4 is attached to the cushion main body 2, the mat 3 is laminated on the plate member 6, the laminated mat 3 is covered with the fixed cover 5, and the cover attaching/detaching portion 50 is provided. and the fixing member attaching/detaching portion 49 are attached, the cushion main body 2 is sandwiched from the outside in the longitudinal direction of the cushion main body 2 by the pair of fixing means 4, and both ends of the cushion main body 2 covered with the fixed cover 5 in the fixed concave portion 48 are fixed. The portion 27 and both ends 62 of the plate member 6 may be inserted (see FIG. 10(b)).

The fixing part 41 is attached to the cushion body 2 via the cover attachment/detachment part 50 by the fixing member attachment/detachment part 49, but may be attached to the cushion body 2 using attachment members such as bolts, strings, and belts. For example, as shown in FIGS. 11A and 11B, the mounting member 402 is horizontally inserted from the outside of the fixing portion 41, and the fixing portion 41 and the plate member 6 are fixed to each other. 41 may be attached to the cushion body 2 .

A string or a belt may be used as the mounting member 402 instead of the bolt or in combination with the bolt. For example, as shown in FIG. It is conceivable to attach the fixing part 41 to the cushion main body 2 by tying the cushion main body 2 and the fixing part 41 with the string 403 passed through the fitting 404 .

Furthermore, the fixed part 41 may be attached to the fixed cover 5 in advance, and may be attached inside the fixed cover 5 as shown in FIGS. 13(a) and 13(b), for example. Specifically, the fixed portions 41 are attached to the inside of the four corners of the rectangular parallelepiped box-shaped fixed cover 5 in the figure, and are considered to be made of rubber. In addition, the fixing portion 41 extends so as to cover the entire height direction of the cushion main body 2 in FIG. Furthermore, it is conceivable that the fixing portion 41 is attached to the fixed cover 5 by an adhesive, for example. It is

It is conceivable that the four fixing parts 41 have the same shape, for example, an elongated shape. In addition, the fixed portion 41 includes a laterally extending surface 412 extending in the lateral direction of the fixed cover 5 and serving as a longitudinal direction restricting portion 412, and a longitudinal extending surface 412 extending in the longitudinal direction of the fixed cover 5 and serving as a lateral direction restricting portion. At least one of the directionally extending surfaces 413 may be provided, and it is conceivable that the fixed portion 41 has both a laterally extending surface 412 and a longitudinally extending surface 413. In this case, in the lateral direction of the fixing portion 41 The cross-sectional shape can be L-shaped. In this structure 1 , the fixing portion 41 can collectively regulate positional deviation in the surface direction of the mat 3 , for example, the longitudinal direction of the cushion body 2 and the lateral direction of the cushion body 2 .

Note that the fixed cover 5 may be provided with a slit 54 in order to facilitate attachment and detachment with respect to the cushion main body 2 . Further, it is conceivable to provide a fastener 55 on the fixed cover 5 as an opening/closing portion 55 that can open and close the slit 54 .

The fixing unit 41 maintains the stacking state of the mats 3 collectively, but the stacking state may be maintained by fixing the positions of at least two overlapping mats 3 among the stacked mats 3. For example, it is conceivable that the mats 3 are provided with snap buttons or hook-and-loop fasteners in order to regulate the positional deviation of the two overlapping mats 3 in the plane direction. In addition, the fixing part 41 may be integrated with the mat 3 constituting the cushion body 2, for example. Concave portions and convex portions provided on the mat 3 are conceivable. Such a fixing portion 41 may be a fitting concave portion provided on one side of the mats 3 that overlap, or a fitting convex portion provided on the other side of the overlapping mats 3 .

As shown in FIG. 14, the fixing means 4 may be provided with locking means 7 for fixing the mats 3 in a laminated state and preventing the mats 3 from being taken out. For example, the lock means 7 is a general lock such as a padlock, or an electric or electronic lock such as a card key. Such locking means 7 can fix the tabs of the cover attaching/detaching portion 50 of the fixed cover 5 in the same figure. By providing the fixing means 4 with the locking means 7, it is possible to prevent the layered state of the mats 3 from collapsing due to a person accidentally removing the fixing means 4 from the cushion body 2 in normal times. Therefore, normally, the structure 1 is used as a bench or the like with the mats 3 prevented from being taken out, and in the event of a disaster or the like, the locking means 7 is released and each mat 3 is taken out from the structure 1 and used. The unlocking of the locking means is performed by the manager of the facility where the structure 1 is installed, the user, or the like.

When the fixed portion 41 is frame-shaped, the thickness and height of the fixed portion 41 may not be uniform. For example, as shown in FIG. 15, the fixing portion 41 is in the shape of a frame surrounding the lower half of each of the pair of long wall surfaces 23 of the cushion body 2 and the entire pair of short wall surfaces 24 of the cushion body 2. can be considered. At this time, in the figure, the height of the portion surrounding the pair of long wall surfaces 23 of the fixing portion 41 is small, and the height of the portion surrounding the pair of short wall surfaces 24 is large, and the fixed cover 5 is the portion of the cushion main body 2. The portion exposed from the fixing portion 41 , for example, the upper half of the cushion body 2 is covered.

Although the fixed cover 5 covers at least a part of the outer peripheral surface of the cushion body 2, the fixed cover 5 may cover the entire side surface and the lower surface 22 of the cushion body in addition to the seat surface 21 of the cushion body. Moreover, the fixed cover 5 may cover at least a portion of the fixed member 40 in addition to the outer peripheral surface of the cushion body 2 . For example, the fixed cover 5 may collectively cover a pair of fixed portions 41 in addition to the cushion main body 2 shown in FIG. 3(a). In this case, the fixed cover 5 may be provided with a through hole penetrating in the thickness direction, and the armrest portion 42 may be exposed from the through hole of the fixed cover 5 . Since the fixing cover 5 covers the fixing part 41 in this way, it becomes difficult for the user to grasp the attachment position of the fixing part 41 to the cushion main body 2 . By removing the attachment of the fixing portion 41, it is possible to prevent the stacking state of the mats 3 from collapsing.

Although the fixed cover 5 has the fastener 55 for opening and closing the slit 54 , instead of the fastener 55 , a snap button or a hook capable of opening and closing the slit 54 may be provided.

At least part of the fixed cover 5 may be made of a stretchable material such as a rubber material. Specifically, the fixed cover 5 may be entirely made of a rubber material. In addition, the fixed cover 5 may have a bag-like shape with a narrow opening into which the mat 3 can be inserted, that is, an opening into which the mat 3 can be inserted, and the opening may be made stretchable by putting rubber in the opening. good. Even in such a case, attachment and detachment of the fixed cover 5 with respect to the cushion main body 2 is easy.

The structure 1 was provided with the fixed cover 5, but the fixed cover 5 may be omitted. good. For example, it is conceivable to store the cushion main body 2 covered with such a decorative cover in the frame-shaped fixing portion 41 . When the cushion main body 2 is attached to the fixed portion 41 without being covered by the decorative cover or the fixed cover 5, the mat 3 may be colored or designed to improve the appearance of the cushion main body 2. be done.

For example, the mat 3 may be a carpet, an inflatable air mat, a blanket, a tatami mat, or the like, other than a foam sheet. The shape of the mat 3 is a substantially elongated plate shape, but it may be a square plate shape, a disk shape, or the like. When the shape of the mat 3 is a square plate, a plurality of the taken out mats 3 can be used by laying them side by side in an emergency. can also be used for sitting.

Although the stacking direction of the mats 3 is the vertical direction, it is conceivable that the mats 3 are stacked in a direction other than the vertical direction, such as the horizontal direction as shown in FIGS. For example, even if the mat 3 is a square plate, in FIG. By doing so, the rectangular parallelepiped cushion main body 2 is configured.

In addition, the mat 3 may be stacked in a plurality of directions other than one direction. For example, the mat 3 may be stacked vertically on top of the mat 3 stacked horizontally. . In addition to being stacked vertically and/or horizontally in an unfolded state, the mats 3 are stacked in a folded state, e.g., the folded mat 3 is stacked vertically and/or horizontally. It is conceivable that It is also conceivable that the cushion body 2 is composed of both the mat 3 in a folded state and the mat 3 in an unfolded state. In this manner, the cushion main body 2 may be composed of the laminated mats 3 regardless of the lamination direction and whether or not the mats 3 are folded.

For example, as shown in FIG. 18(a), the mat 3 has at least one, more specifically, three polygonal lines α at one end in the longitudinal direction, and by folding along the polygonal lines α, It is conceivable that the pillow portion 34 is formed as shown in FIG. 18(b). In this case, when a person lies down on each of the mats 3 taken out, the head can be placed on the pillow portion 34, so that the comfort of sleeping on the mat 3 can be improved. It should be noted that the thickness of the mat 3 may be not only uniform but also partly thick, and the thick part is composed of a pillow when using each mat from which the thick part is taken out and the laminated mat 3. It is also conceivable that it also serves as an armrest or the like of the cushion body 2 .

The cushion body 2 may include mats 3 of different types in addition to being composed of one type of mat 3 . For example, the cushion body 2 may be constructed by laminating a foam sheet and then laminating a carpet or a blanket, or by alternately laminating a foam sheet and a carpet. When the cushion body 2 is configured by laminating a plurality of pairs of foam sheets and blankets, one pair of foam sheets and blankets can be provided to each person in the event of a disaster or an event. In this case, the user can use the foam sheet as a rug and put a blanket on it.
