Description

[Technical field]

[0001] The present invention relates to a three-dimensional structure assembly kit capable of assembling a three-dimensional structure by connecting a plurality of plate-like members. to, and three-dimensional structures. [Background technology]

[0002] In the event of a disaster or other emergency, it has become common for large spaces to be appropriately partitioned to provide residents with habitable private space for those who have evacuated to local gymnasiums, community centers, etc. Securing private space is not only effective from the perspective of protecting privacy and allowing residents to spend their time in peace, but also from the perspective of preventing the spread of various infectious diseases.

[0003] Patent Document 1 describes an invention relating to a partition unit that includes partition plates with small holes for connection formed near the sides and ends of rectangular plates, and a connecting belt that connects the partition plates. The sides or ends of a pair of partition plates are arranged to butt against each other, and a connecting belt made of a flat fastener is passed through the small holes of each butted partition plate in sequence to connect the partition plates. By connecting multiple partition plates in this way, a large space can be divided into private spaces of appropriate size. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2007-113366 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, preparing partition units only for emergencies and the like is not only costly, but also requires a large storage space to secure a storage location. Therefore, it is conceivable to use them as boards for constructing storage boxes or fences for storing balls and mats in gymnasiums and the like during normal times other than emergencies, and then repurpose these boards as partition boards in emergencies. The connecting belts connecting the boards to each other are removed, and the connection state of the boards is appropriately rearranged and reconnected. This allows the gymnasium equipment to be repurposed as partition units to partition private spaces of appropriate size.

[0006] In order to repurpose gymnasium equipment into partition units, it is necessary to make it possible to easily connect and rearrange the partition panels. In addition, in the event of an emergency, many residents may evacuate to public spaces such as gymnasiums at the same time, so it is necessary to make it possible to quickly connect and rearrange the partition panels. Furthermore, since the number of residents evacuating and their situations vary, it is also necessary to be able to easily divide the space into appropriate sizes as needed.

[0007] However, the partition board described in Patent Document 1 is a 180 cm x 90 cm reinforced cardboard board made of paper. When connecting the partition boards, the sides or ends of the partition boards must be butted together, a connecting belt must be inserted into each of the small holes formed in the pair of partition boards, and the partition boards must be fixed with a flat fastener each time. Therefore, the connecting work with the connecting belt requires time and effort, and it is difficult to install the partition units simply and quickly. There is a demand for improving the ease of assembly of three-dimensional structures. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides a three-dimensional structure assembly kit capable of assembling a three-dimensional structure by connecting a plurality of rectangular plate-like members, the three-dimensional structure assembly kit comprising: a flat plate-like member; and a connecting member connecting a pair of the plate-like members; the plate-like member comprises a plurality of rectangular plate materials and a side member; a plurality of convex portions protruding in a direction along a main surface of the plate material and concave portions recessed relatively to the convex portions in a direction along the main surface; and the plate-like members are configured such that the sides of the pair of plate materials are butted together to connect the convex portions of one of the plate materials to the front of the other of the plate materials. The connecting member is formed into a flat plate by engaging with the recess, and the side members are attached so as to span both side edges of the pair of plate materials. The connecting member is integrally formed with a first support portion that supports a side edge of one of the pair of plate-shaped members, and a second support portion that supports a side edge of the other of the pair of plate-shaped members. The sides of the pair of plate-shaped members are butted together, and the side edge of one of the plate-shaped members is supported by the first support portion and the side edge of the other plate-shaped member is supported by the second support portion, so that the pair of plate-shaped members can be connected in a state where they cross each other.

[0009] According to the above configuration, when connecting plate-like members, for example, the first support part of the connecting member is attached to the side of one of the pair of plate-like members, and the side of the other plate-like member is attached to the second support part. By attaching the pair of plate-like members to each of the two support parts of one connecting member, the pair of plate-like members can be easily connected. In addition, when the pair of plate-like members is connected, the pair of plate-like members cross each other. By sequentially connecting multiple plate-like members, a three-dimensional structure of an appropriate size can be easily and quickly assembled. The workability of assembling the three-dimensional structure can be improved.

[0010] The plate-like member has a plurality of rectangular plate materials with convex portions and concave portions formed therein, and a side member. The sides of the pair of plate materials are butted together, the convex portions are engaged with the concave portions, and the side member is attached so as to straddle both sides of the pair of plate materials. Therefore, by changing the number of plate materials forming the plate-like member, the size and shape of the plate-like member can be easily changed. The convenience of the three-dimensional structure can be improved.

[0011] Here, a three-dimensional structure refers to a structure in which plate-like members are assembled three-dimensionally. For example, a partition that divides a space by connecting multiple plate-like members, a storage box for storing balls, mats, etc. in a gymnasium, etc., formed by connecting multiple plate-like members, etc., can be mentioned. The same applies below.

[0012] In order to solve the above problems, the plate-like member of the present invention is a rectangular plate-like member used for connecting multiple sheets to assemble a three-dimensional structure, and has multiple rectangular plate materials and side members, and the side edges of the plate materials are integrally formed with multiple convex portions protruding in a direction along the main surface of the plate materials and concave portions that are recessed relatively to the convex portions in a direction along the main surface, and the plate-like member is formed into a flat plate-like shape by butting the sides of a pair of the plate materials together and engaging the convex portions of one of the plate materials with the concave portions of the other plate material, and the side members are attached so as to span both side edges of the pair of the plate materials.

[0013] According to the above configuration, the plate-like member is formed by connecting a plurality of plate materials and attaching the side members so as to straddle both sides of the adjacent plate materials. Therefore, the engaging portions of the plurality of plate materials are reinforced by the side members. The plate-like members are prevented from being deformed when assembling the three-dimensional structure. The workability of assembling the three-dimensional structure can be improved.

[0014] Furthermore, the plate-like member is formed with a pair of plate members to which side members are attached as the smallest unit. Therefore, the size and shape of the plate-like member can be easily changed by changing the number of plate members that form the plate-like member. This makes it possible to easily assemble a three-dimensional structure of an appropriate size and shape. Compared to connecting plate-like members of a fixed size and shape, there are fewer restrictions on the size and shape of the three-dimensional structure to be assembled. This can improve the convenience of the three-dimensional structure.

[0015] In order to solve the above problems, the three-dimensional structure of the present invention is a three-dimensional structure formed by connecting a plurality of rectangular flat plate-like members with connecting members, the plate-like members having a plurality of rectangular plate materials and side edge members, the side edges of the plate materials being integrally formed with a plurality of convex portions protruding in a direction along a main surface of the plate materials and concave portions recessed relatively to the convex portions in a direction along the main surface, and the plate-like members are configured to engage with each other by butting the sides of a pair of the plate materials together and engaging the convex portions of one of the plate materials with the concave portions of the other plate material. The connecting member is formed in a flat plate shape with the side members attached so as to span both side edges of the pair of plate members, and a first support portion supporting a side edge of one of the pair of plate members and a second support portion supporting a side edge of the other of the pair of plate members are integrally formed, and the pair of plate members are connected in a crossing state with the side edge of one of the plate members supported by the first support portion and the side edge of the other of the plate members supported by the second support portion.

[0016] According to the above configuration, the three-dimensional structure is formed by connecting a plurality of plate-like members in a mutually intersecting manner by the connecting members. Since the connecting members are formed with a first support portion and a second support portion, a pair of plate-like members are connected by attaching them to each of the two support portions of one connecting member. The connecting state by the connecting members is simple, and the assembly workability is good. By changing the number of plate-like members to be connected, a three-dimensional structure of an appropriate size can be easily and quickly assembled.

[0017] In addition, the plate-like members are formed by butting the sides of the plate materials together, engaging the convex portions with the concave portions, and attaching the side members so as to straddle both sides of the adjacent plate materials. Therefore, by changing the number of plate materials that form the plate-like members, the size and shape of the three-dimensional structure can be easily changed. This improves the convenience of the three-dimensional structure. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, one embodiment of a three-dimensional structure embodying the present invention will be described. As shown in Fig. 1, the three-dimensional structure of this embodiment is a partition 1 for dividing a large space into appropriate small spaces. The partition 1 is used, for example, in the event of an emergency such as a disaster, to divide and provide living spaces with privacy for residents who have evacuated to a gymnasium, a community center, or the like. The partition 1 shown in Fig. 1 has two long side walls 2 with a height of about 1.6 m and a width of about 2.0 m, and two short side walls 3 with a height of about 1.6 m and a width of about 1.2 m. An entrance 4 is formed in a part of one of the long side walls 2.

[0021] The partition 1 has plate-like members 10 and curved connecting members 50. The partition 1 is formed by connecting a plurality of rectangular plate-like members 10 with curved connecting members 50.

[0022] <Regarding the plate-like member 10> 2, the plate-shaped member 10 is formed by engaging plate materials 20, which will be described later. The size and shape of the plate-shaped member 10 can be changed depending on the number of plate materials 20. The plate-shaped members 10 of any size and shape have a thickness of about 3 cm.

[0023] There are three types of plate-like members 10 used in the partition 1 of this embodiment, which differ in size and shape. The plate-like members 10 shown in FIG. 2 form the short side wall 3 of the partition 1 and the long side wall 2 in which the entrance 4 is formed. The plate-like member 10 shown here is a plate-like member 10b in which plate materials 20 are engaged in four vertical rows and three horizontal rows, and is a rectangular plate with a long side length of about 160 cm and a short side length of about 120 cm. In the following explanation, plate-like members 10a to 10e will appear depending on the number of plate materials 20 that constitute the plate-like member 10, but when matters common to the plate-like members 10a to 10e are explained, they will be referred to as the plate-like member 10.

[0024] As shown in Fig. 2, the plate-like member 10 includes a plate material 20, a side member 30, and a corner member 40. The plate-like member 10 is formed by engaging a plurality of plate materials 20. The side members 30 are attached so as to straddle both side members 21 of adjacent plate materials 20. The corner members 40 are attached so as to cover each of the four corners of the plate-like member 10. Note that, in all plate-like members 10 having different sizes and shapes, the plate materials 20, side members 30, and corner members 40 are formed from common members.

[0025] <About Board 20> 3, the plate material 20 of this embodiment is formed in the shape of a square plate with a side 21 having a length L1 of about 40 cm. A plurality of protrusions 22 protruding in a direction along the main surface of the plate material 20 are formed on each side 21 of the plate material 20. By forming the protrusions 22 on the side 21 of the plate material 20, a plurality of recesses 23 recessed relatively to the protrusions 22 in a direction along the main surface are formed.

[0026] The positions at which the convex portion 22 and the concave portion 23 are formed are different on the opposing sides 21 of the plate material 20. On the upper side 21 shown in FIG. 3, the convex portion 22 is formed on the right edge, while on the lower side 21, the concave portion 23 is formed on the right edge. That is, when the side 21 extending in the left-right direction is viewed in FIG. 3, the concave portion 23 is formed on the lower side 21 at the position where the convex portion 22 is formed on the upper side 21. Also, on the right side 21 shown in FIG. 3, the concave portion 23 is formed on the upper edge, while on the left side 21, the convex portion 22 is formed on the upper edge. That is, when the side 21 extending in the up-down direction is viewed in FIG. 3, the convex portion 22 is formed on the left side 21 at the position where the concave portion 23 is formed on the right side 21.

[0027] The plate material 20 of the present embodiment is made of a foamed resin material. There is no particular limitation on the material, and examples of the material include polypropylene, polyurethane, polystyrene, phenolic resin, and polyvinyl chloride.

[0028] <Side Member 30 and Corner Member 40> As shown in Fig. 4, the side member 30 attached to the side 21 of the plate material 20 includes a pair of side walls 31 and a connecting wall 32 that connects the pair of side walls 31. The short-side end edges of the pair of side walls 31 extending in parallel are connected by the connecting wall 32 to form a U-shaped cross section. The internal space surrounded by the pair of side walls 31 and the connecting wall 32 is a groove-shaped space that extends in the longitudinal direction of the side member 30, and is the portion that houses the side 21 of the plate material 20.

[0029] The pair of side walls 31 are formed so that their short-side lengths L2 are equal to each other. The short-side length L2 is about 3 cm to 4 cm. The length L3 in the longitudinal direction of the side member 30 is about 20 cm, which is about half the length L1 of the side edge 21 of the plate material 20. The length L4 between the inner faces of the pair of side walls 31, i.e., the short-side length L4 of the inner face of the connecting wall 32, is slightly longer than the thickness of the plate material 20, and is about 3 cm.

[0030] 2, the side member 30 is attached in such a manner that it straddles the side edges 21 of the two plate materials 20 with the protrusions 22 and recesses 23 of the two plate materials 20 engaged with each other. At this time, the side member 30 is attached so that the side edges 21 of the two plate materials 20 are accommodated by equal lengths in the groove-shaped internal space. In other words, the side member 30, whose longitudinal length L3 is about 20 cm, is attached so as to accommodate about 10 cm of the side edge 21 of one plate material 20 and about 10 cm of the side edge 21 of the other plate material 20.

[0031] 5, the corner member 40 attached to the corner portion of the plate material 20 is formed into an L-shaped bent shape when viewed from the front. Although the shape when viewed from the front is different, the basic structure is the same as the side member 30.

[0032] The corner member 40 is formed with a U-shaped cross section and includes a pair of side walls 41 and a connecting wall 42 that connects the pair of side walls 41. The internal space surrounded by the pair of side walls 41 and the connecting wall 42 is a groove-shaped space extending in the longitudinal direction of the corner member 40, and is the portion that accommodates the corner portion of the plate material 20.

[0033] The short-side lengths L5 of the pair of side walls 41 are equal to each other and are about 3 cm to 4 cm. The short-side length L5 of the side walls 41 is equal to the short-side length L2 of the side walls 31 of the side member 30. The longitudinal length L6 of the connecting wall 42 is about ¼ of the length L1 of the side edge 21 of the plate material 20. The longitudinal length L6 of one connecting wall 42 is about half the longitudinal length L3 of the side member 30, and is about 10 cm. The length between the inner surfaces of the pair of side walls 41 is equal to the length L4 between the inner surfaces of the pair of side walls 31 of the side member 30.

[0034] 2, the corner members 40 are attached to the corners of the plate material 20 that is disposed at the corners of the plate-shaped member 10. At this time, the corner members 40 are attached so that the groove-shaped internal spaces thereof each accommodate approximately 10 cm of the adjacent side edges 21.

[0035] The material of the side member 30 and the corner member 40 is not particularly limited. Examples of the material include synthetic resin materials and metal materials. The side member 30 of the present embodiment is formed of a thermoplastic resin material. The thermoplastic resin material is not particularly limited. Examples of the thermoplastic resin material include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyurethane, and acrylonitrile-butadiene-styrene.

[0036] <Regarding the bent connecting member 50> 6, the bent connecting member 50 has a shape in which a first support part 51 having a U-shaped cross section and a second support part 52 also having a U-shaped cross section are integrally connected so as to be perpendicular to each other. The basic structures of the first support part 51 and the second support part 52 are similar to those of the side member 30. The bent connecting member 50 corresponds to the connecting member referred to in the claims.

[0037] The first support portion 51 includes a pair of side walls 53 and a connecting wall 54 connecting the pair of side walls 53. The second support portion 52 includes a pair of side walls 55 and a connecting wall 56 connecting the pair of side walls 55. The first support portion 51 and the second support portion 52 are formed in a shape extending in a direction perpendicular to each other, with the connecting wall 56 of the second support portion 52 being integrated with one side wall 53 of the first support portion 51. One outer wall 50a of the bent connecting member 50 is formed by one side wall 53 of the first support portion 51. The other side wall 50b of the bent connecting member 50 is formed by connecting the connecting wall 54 of the first support portion 51 and one side wall 55 of the second support portion 52 in a planar manner.

[0038] The internal space surrounded by the pair of side walls 53 and the connecting wall 54 in the first support portion 51 is a groove-shaped space extending in the longitudinal direction of the first support portion 51, and is a portion in which the side edge 21 of the plate material 20 is accommodated. Similarly, the internal space surrounded by the pair of side walls 55 and the connecting wall 56 in the second support portion 52 is a groove-shaped space extending in the longitudinal direction of the second support portion 52, and is a portion in which the side edge 21 of the plate material 20 is accommodated. The groove-shaped space formed in the first support portion 51 corresponds to the first groove in the claims. Also, the groove-shaped space formed in the second support portion 52 corresponds to the second groove in the claims.

[0039] A length L7 in the short side direction of the side wall 53 of the first support portion 51 and the side wall 55 of the second support portion 52 is equal to a length L2 in the short side direction of the side wall 31 of the side member 30. A length L8 in the longitudinal direction of the bent connecting member 50 is equal to a length L3 in the longitudinal direction of the side member 30, and is approximately half the length L1 of the side edge 21 of the plate material 20. A length between the inner surfaces of the pair of side walls 53, 55 is equal to a length L4 between the inner surfaces of the pair of side walls 31 of the side member 30.

[0040] <How to assemble Partition 1> Next, a method for assembling the partition 1 using the plate-like members 10 and the bent connecting members 50 will be described together with its function.

[0041] In the partition 1 shown in Fig. 1, the long side wall 2 where the entrance 4 is not formed is formed of plate-like members 10a in which four vertical rows and five horizontal rows of plate materials 20 are engaged. The short side wall 3 is formed of plate-like members 10b in which four vertical rows and three horizontal rows of plate materials 20 are engaged. First, the plate-like members 10a and 10b are prepared.

[0042] A side member 30 and a corner member 40 are attached to the plate-like member 10. The length L3 of the side member 30 in the longitudinal direction is approximately half the length L1 of the side 21 of the plate material 20, and the side member 30 is attached so as to accommodate the side edges 21 of the two plate materials 20 by the same length. The length L6 of the connecting wall 42 of the corner member 40 in the longitudinal direction is approximately ¼ the length L1 of the side edge 21 of the plate material 20. Therefore, the side edge 21 of the plate material 20 is exposed on the side of the plate-like member 10 by approximately half the length L1 of the side edge 21 of the plate material 20.

[0043] The first support portion 51 of the bent connecting member 50 is attached to the short side of the plate member 10a. At this time, the bent connecting member 50 is attached to the portion where the side edge 21 of the plate material 20 is exposed. Since the length L8 of the bent connecting member 50 in the longitudinal direction is about half the length L1 of the side edge 21 of the plate material 20, the entire exposed portion of the side edge 21 of the plate material 20 is accommodated in the groove-shaped space of the first support portion 51. The bent connecting member 50 is attached to the entire portion where the side edge 21 of the plate material 20 is exposed. As a result, the side edge of the plate member 10a is covered with the side edge member 30, the corner member 40, and the bent connecting member 50 with almost no gaps. In addition, the bent connecting members 50 are attached to the side edge of the plate member 10a at regular intervals.

[0044] Next, the longitudinal side edge of the plate-shaped member 10b constituting one of the short side walls 3 is inserted into the groove-like space of the second support portion 52 of the bent connecting member 50 attached to the plate-shaped member 10a. At this time, the second support portion 52 is positioned in the side edge of the plate-shaped member 10a in a portion where the side edge 21 of the plate material 20 is exposed. Therefore, when the side edge of the plate-shaped member 10b is inserted into the second support portion 52, the side edge of the plate-shaped member 10b is covered with the side edge member 30, the corner member 40, and the bent connecting member 50 with almost no gaps.

[0045] The length L4 between the inner surfaces of the pair of side walls 31 of the side member 30 is slightly longer than the thickness of the plate material 20. The length between the inner surfaces of the pair of side walls 41 of the corner member 40 is equal to the length L4 between the inner surfaces of the pair of side walls 31 of the side member 30. The length between the inner surfaces of the pair of side walls 53, 55 of the bent connecting member 50 is equal to the length L4 between the inner surfaces of the pair of side walls 31 of the side member 30. Therefore, at the sides of the plate members 10a, 10b, the inner surfaces of the side member 30, the corner member 40, and the bent connecting member 50 are in contact with the outer surface of the plate material 20.

[0046] The short-side length L2 of the side wall 31 of the side member 30 is equal to the short-side length L5 of the side wall 41 of the corner member 40. The short-side length L7 of the side wall 53 of the first support portion 51 and the side wall 55 of the second support portion 52 of the bent connecting member 50 is equal to the short-side length L2 of the side wall 31 of the side member 30. Therefore, on the sides of the plate-like members 10a, 10b, the positions of the short-side edge portions of the side member 30, the corner member 40, and the bent connecting member 50 are aligned so as to form a substantially straight line.

[0047] In this manner, the plate-like members 10a, 10b are connected and fixed in a perpendicular state. In the same manner, the plate-like member 10b constituting the other short side wall 3 is connected. Furthermore, as shown in Fig. 1, the plate-like members 10b and 10c constituting the long side wall 2 in which the inlet 4 is formed are connected. Through this series of operations, a space partitioned by the long side wall 2 and the short side wall 3 is formed, as shown in Fig. 1.

[0048] <About conversion to other forms of three-dimensional structures> The partition 1 of this embodiment is used, for example, to provide residents who have evacuated to a gymnasium or a community center in an emergency with a living space that ensures privacy. The plate-shaped member 10 and the bent connecting member 50 used for the partition 1 in an emergency can be used for other purposes other than emergencies, thereby expanding the convenience. In other words, by using the plate-shaped member 10 for other purposes in normal times and reassembling it into the partition 1 in an emergency, there is no need to prepare members required only for emergencies. By repurposing members that are normally used for emergencies, not only can the costs for dedicated items for emergencies be reduced, but storage space can also be reduced.

[0049] Here, conversion to other forms will be described. 7 shows a ball cage 5 for storing balls used in, for example, physical education classes at school. The ball cage 5 is formed of four plate-like members 10d in which plate materials 20 are engaged in two vertical rows and three horizontal rows, and three plate-like members 10e in which plate materials 20 are engaged in one vertical row and three horizontal rows. The plate-like members 10d are connected to each other with bent connecting members 50, and the plate-like members 10d and 10e are connected to each other with straight connecting members 60, which will be described later.

[0050] Although not shown, for example, the plate-like member 10 can be used as a wall protection panel to be installed on the wall of a school gymnasium or the like. The wall protection panel can be formed by connecting a plurality of plate-like members 10 with straight connecting members 60. It protects the wall of the gymnasium when a ball is thrown at the wall during a physical education class or the like. It can also absorb the impact when the ball hits the wall during a physical education class.

[0051] In this way, under normal circumstances, the plate-like members 10, the curved connecting members 50, and the straight connecting members 60 are used as gymnasium equipment, and in an emergency, the plate-like members 10, the curved connecting members 50, and the straight connecting members 60 that make up these equipment can be rearranged and repurposed into the required three-dimensional structure.

[0052] For example, when a large number of residents evacuate to a gymnasium due to an earthquake, wind or flood damage, the ball cages 5 and wall protection panels used as gymnasium equipment are removed. These equipment are then disassembled into their component parts, the plate-shaped members 10, the curved connecting members 50, and the straight connecting members 60, and reassembled into partitions 1, 6, etc. as necessary.

[0053] The side of the plate-like member 10 has a portion where the side 21 of the plate material 20 is exposed. This exposed portion is the middle portion of the side 21 of the plate material 20, and its length is approximately equal to the length L8 of the bent connecting member 50 in the longitudinal direction. Therefore, when rearranging the connection state of the plate-like member 10 and the bent connecting member 50, it is easy to understand how to assemble them. Even if the plate-like member 10 has a different size or shape, it is easy to understand how to assemble them, so even children can easily assemble them. If the plate-like member 10 and the bent connecting member 50 are assembled like a puzzle, a three-dimensional structure of an appropriate size can be easily formed. Even without an instruction manual for assembly, it can be assembled just by looking at each part.

[0054] The partition 1 of this embodiment provides the following effects. (1) The partition 1 of this embodiment is assembled using a kit made up of plate-like members 10 and curved connecting members 50. The curved connecting members 50 are formed with a first support portion 51 and a second support portion 52 that support the sides of the plate-like members 10. If the side of one of a pair of plate-like members 10 is supported by the first support portion 51 and the side of the other plate-like member 10 is supported by the second support portion 52, the plate-like members 10 are connected in a perpendicular state.

[0055] Therefore, it is possible to easily connect the pair of plate-like members 10. In addition, since the pair of plate-like members 10 are perpendicular to each other when connected, the partition 1 can be easily and quickly assembled by sequentially connecting a plurality of plate-like members 10. This improves the workability of assembling the partition 1.

[0056] (2) The bent connecting member 50 is formed in an elongated shape, and the first support portion 51 and the second support portion 52 are formed in a groove shape extending in the longitudinal direction of the bent connecting member 50. Therefore, the plate-like members 10 can be easily assembled together by inserting the sides of the plate-like members 10 into the groove-shaped first support portion 51 and second support portion 52. Assembly of the plate-like members 10 is easy.

[0057] (3) The plate-like member 10 is formed as a minimum unit in which a pair of plate members 20 and side members 30 are attached to each other. Therefore, the size and shape of the plate-like member 10 can be easily changed by changing the number of plate materials 20 that form the plate-like member 10. A partition 1 of an appropriate size and shape can be easily assembled.

[0058] (4) The plate-like member 10 is formed into a flat plate shape by the engagement of the protrusions 22 and recesses 23 of the multiple plate materials 20 . This stably assembles the plate members 20 together. In addition, the protrusions 22 and recesses 23 can be temporarily fastened together, facilitating assembly work using the side members 30 and the bent connecting members 50. Furthermore, the engagement is stable even in parts other than the side edges of the plate members 10.

[0059] (5) The plate-shaped member 10 is formed by attaching the side members 30 so as to straddle the side edges 21 of the adjacent plate members 20 . Therefore, the engaging portions of the plurality of plate materials 20 are reinforced, and the strength of the plate-like member 10 is maintained. The workability of assembling the partition 1 is improved, and the assembled partition 1 is stable.

[0060] (6) Corner members 40 are attached to the corners of the plate-like member 10 . This reinforces the corners of the plate-shaped member 10, improving the durability of the plate-shaped member 10. (7) The lengths L3, L6, L8 of the side members 30, the corner members 40, and the curved connecting members 50 are set so that the sides of the plate-like member 10a are covered with the side members 30, the corner members 40, and the curved connecting members 50 with almost no gaps.

[0061] Therefore, the protrusions 22 and recesses 23 of the side edges 21 of the plate material 20 are not exposed at the connecting portions. Wear of the protrusions 22 at the connecting portions is suppressed, and the durability of the plate-like member 10 is improved.

[0062] (8) At the side of the plate-like member 10, the side 21 of the plate material 20 is exposed by a length for attaching the bent connecting member 50. Therefore, they can be easily connected by simply inserting the first support part 51 and the second support part 52 of the curved connecting member 50 into the exposed parts. Even without an instruction manual for assembly, the assembly method can be easily understood just by looking at the plate-like member 10 and the curved connecting member 50. The partition 1 etc. can be smoothly assembled even in a chaotic situation such as during an emergency.

[0063] (9) The plate-like members 10 can be easily connected by inserting the bent connecting members 50 into the first support portions 51 and the second support portions 52 . Therefore, even if you assemble it incorrectly, it can be easily corrected.

[0064] (10) On opposing sides 21 of the plate material 20, the positions at which the protrusions 22 and the recesses 23 are formed are different. Therefore, the two plate members 20 can be easily engaged by simply butting the side edges 21 of the two plate members 20 together. The procedure for changing the size and shape of the plate-like members 10 is easy to understand.

[0065] (11) The plate material 20 of this embodiment is made of a material capable of absorbing shock, such as a foamed resin material. Therefore, it is lightweight and has excellent durability. Even if the plate-shaped member 10 used in normal times is diverted to an emergency, it is easy to handle. It can also withstand conversion between normal and emergency situations. Furthermore, it can be easily cut or processed to an appropriate size. If it is damaged, it can be recycled, and it can be molded using recycled materials made of the same material.

[0066] (12) The plate-like members 10 are connected to each other by the bent connecting members 50 attached at regular intervals. Therefore, the plate members 10 are connected to each other stably.

[0067] The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other as long as they are not technically inconsistent.

[0068] Besides the partition 1 shown in FIG. 1, a partition 6 for partitioning a smaller space as shown in FIG. 8 can be used as a three-dimensional structure for use in an emergency. For example, in the partition 1 shown in FIG. 1, the long side wall 2 where the entrance 4 is not formed is formed of a plate-like member 10a in which four rows of plate materials 20 are engaged vertically and five rows of plate materials 20 are engaged horizontally. The partition 6 shown in FIG. 8 is formed with the plate-like members 10d and 10e used in the ball cage 5 in a changed orientation. In this way, in the partition 6 for partitioning a smaller space, a curtain-like member can be installed at the entrance 4 as necessary to be used as a changing space or the like. By changing the number of plate materials 20 constituting the plate-like member 10, partitions 1 of different sizes and shapes can be assembled.

[0069] The plate-like members 10 may be connected by a connecting member other than the bent connecting member 50. The ball cage 5 shown in Fig. 7 and the partition 6 shown in Fig. 8 are formed in a flat plate shape by connecting plate-like members 10d, 10e by a straight connecting member 60.

[0070] 9, the straight connecting member 60 has a shape in which a first support part 61 having a U-shaped cross section and a second support part 62 also having a U-shaped cross section are connected together in a plane. The basic structures of the first support part 51 and the second support part 52 are similar to those of the bent connecting member 50.

[0071] The straight connecting member 60 includes a pair of side walls 63 and a connecting wall 64 extending in the longitudinal direction at the center in the short direction of the pair of side walls 63. As a result, in the internal space of the pair of side walls 63, with the connecting wall 64 as a boundary, a first support portion 61 extending in a groove-like manner in the longitudinal direction is formed on one side, and a second support portion 62 extending in a groove-like manner in the longitudinal direction is formed on the other side.

[0072] A length L9 from the connecting wall 64 to the short-side end edge of the side wall 63 is equal to a short-side length L2 of the side wall 31 of the side member 30. A longitudinal length L10 of the straight connecting member 60 is equal to a longitudinal length L3 of the side member 30, and is approximately half the length L1 of the side edge 21 of the plate material 20. A length between the inner surfaces of the pair of side walls 63 is equal to a length L4 between the inner surfaces of the pair of side walls 31 of the side member 30.

[0073] The method of connecting the plate-like members 10 with the straight connecting members 60 is the same as that of the curved connecting members 50. The plate-like members 10 are connected in a planar shape by the connection with the straight connecting members 60. Like the ball cage 5 and the partition 6, by connecting a plurality of plate-like members 10 with the straight connecting members 60 to form a planar side wall, the strength of the side wall can be improved.

[0074] As shown in Figures 1, 7, and 8, the side members 30 may be attached to the portions of the plate member 10 to which the curved connecting members 50 and the straight connecting members 60 are not connected. In other words, all of the side edges 21 of the plate member 20 may be covered with the side members 30, the corner members 40, the curved connecting members 50, and the straight connecting members 60. Then, the partition 1 or the like may be completed when all of the side edges 21 are covered. This improves the strength of the three-dimensional structure. It also makes it easier to block the view from the outside.

[0075] 4, claws 33 extending inward may be formed on the inner surface of the side member 30. The claws 33 bite into the plate material 20, and the side member 30 is firmly fixed. As shown in FIG. 8, a side member 34 having a length extending along the entire length of the side of the plate-shaped member 10 may be attached to a portion of the plate-shaped member 10 to which the curved connecting member 50 and the straight connecting member 60 are not connected.

[0076] The plate-shaped member 10 in the above embodiment includes the plate material 20, the side members 30, and the corner members 40, but the corner members 40 may be omitted. In the plate-shaped member 10b of the above embodiment, the side members 30 are attached to the left and right side edges and the top and bottom side edges shown in Fig. 2 to fix the plate materials 20 together, and the plate materials 20 are not fixed together at parts other than the side edges. This is not limiting, and the plate materials 20 may be fixed together at parts other than the side edges of the plate-shaped member 10b.

[0077] 11, the portions where the corners of the four plate materials 20 butt against each other are cut, and a reinforcing member 80 may be joined to cover these portions. The reinforcing member 80 fixes the plate materials 20 together and favorably maintains the shape of the plate member 10. The same applies to other plate members 10 having portions where the corners of the four plate materials 20 butt against each other.

[0078] The plate material 20 in this embodiment is formed in a square plate shape with the length L1 of the side 21 being about 40 cm, but the size is not limited to this. For example, the length L1 of the side 21 may be about 30 cm. Furthermore, the plate material 20 is not limited to a square plate shape. For example, it may be a rectangular plate shape.

[0079] The shapes of the protrusions 22 and the recesses 23 formed on the plate material 20 are not limited to those in the above embodiment. It is sufficient that the positions of the protrusions 22 and the recesses 23 on the opposing sides 21 are different and the protrusions 22 and the recesses 23 can be engaged with each other.

[0080] In the above embodiment, the lengths L3, L6, and L8 of the side member 30, the corner member 40, and the bent connecting member 50 are set so as to cover the side of the plate-like member 10a with almost no gaps, but are not limited to this. The lengths L3, L6, and L8 may be shorter.

[0081] The side members 30 do not have to be attached so as to cover the same length of the side edges 21 of the adjacent plate members 20. They may be attached so as to cover a longer length of one of the side edges 21.

[0082] The short-side lengths L2 of the pair of side walls 31 of the side member 30 are formed to be equal to each other, but are not limited to this. The short-side lengths of the pair of side walls 31 may be different from each other. The same applies to the corner member 40, the bent connecting member 50, and the straight connecting member 60.

[0083] The short-side length L2 of the pair of side walls 31 of the side member 30, the short-side length L5 of the pair of side walls 41, and the short-side length L7 of the pair of side walls 53, 55 of the bent connecting member 50 may be different from each other.

[0084] The bent connecting member 50 does not have to connect the first support portion 51 and the second support portion 52 so as to be perpendicular to each other. It is sufficient that they are connected so as to intersect at an angle. The bent connecting member 50 is not limited to the shape of the above embodiment, as long as it has a first support portion and a second support portion that can connect the plate-like members 10 in a crossing state.

[0085] In the bent connecting member 70 shown in FIG. 10, a first support portion 71 and a second support portion 72, each having a U-shaped cross section, are connected to each other at right angles via a cylindrical space portion 73. When the bent connecting member 70 has such a shape, for example, the bent connecting member 70 can be attached to the plate-shaped member 10 in such a manner that the upper surface of the bent connecting member 70 is exposed, thereby connecting two three-dimensional structures to each other. Specifically, the two three-dimensional structures are butted together at the position of the bent connecting member 70, and a connecting jig having a pair of legs that can be inserted into the space portion 73 of each of the bent connecting members 70 is inserted from above. This allows the two three-dimensional structures to be fixed at the position of the bent connecting member 70. When partitioning a place such as a gymnasium, a plurality of three-dimensional structures can be connected to each other to suppress their positional deviation.

[0086] The plate material 20 in the above embodiment is made of a foamed resin material, but is not limited thereto. For example, it may be a hollow structure made of a synthetic resin material. Examples of such hollow structures include those described in Japanese Patent No. 5514470, Japanese Patent No. 4368399, Japanese Patent Publication No. 10-156985, and Japanese Patent Publication No. 2014-205341.
