Description

[Technical Field]

[0001] The present invention relates to a simple partition material that is suitable for use in evacuation shelters and the like during disasters to ensure private space for disaster victims, and to a partition using the same. [Background technology]

[0002] In the event of a disaster, gymnasiums and other indoor facilities are used as evacuation shelters for disaster victims. In these shelters, simple partitions are installed to ensure the privacy of evacuees. The partitions are made by arranging multiple cardboard sheets in a rectangular shape in a plan view and connecting the cardboard sheets to create partitioned spaces. This allows disaster victims to have private spaces.

[0003] For example, Patent Document 1 discloses a cardboard partition structure in which a plurality of partition plates of the same type are connected and arranged, with end plates connected to the left and right edges of side plates with a center crease via respective folds, with one end plate portion of two partition plates bent into an L shape along the center crease overlapping the other, and another partition plate is arranged at the lower edge of the side plate that floats above the center crease so that the vertically standing end plate overlaps the other, and connecting portions are provided at the overlapping parts of the side plates and end plates where connecting material can be inserted, and a cardboard partition structure in which one or more U-shaped partitions are arranged and fixed in place is disclosed. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-328834 Summary of the Invention [Problem to be solved by the invention]

[0005] The cardboard partition structure disclosed in Patent Document 1 can be easily assembled using a single type of part. However, it is only used in the event of a disaster and must be disassembled and stored afterwards. Therefore, cardboard, which is prone to folding in the grain direction (width direction), is prone to creases when assembling, disassembling, transporting, and storing the partition structure. Furthermore, when disaster victims' clothes or belongings that have become wet from rain come into contact with the cardboard during evacuation, those parts are prone to deformation or loss of strength.

[0006] The present invention solves the above-mentioned problems and provides a partition material that is easy to assemble when in use and is resistant to deformation and loss of strength even after repeated use, and a partition using the same. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention has the following configuration. In other words, the partition material of the present invention is a partition material comprising a synthetic resin sheet material and metal foil laminated on the front and back of the sheet material, and has hinge portions formed continuously along the longitudinal direction at both widthwise ends, a central portion arranged between the hinge portions, and edge portions arranged on the opposite side of the hinge portions from the central portion, and the hinge portions do not have the metal foil on either the front or back along the longitudinal direction, so the sheet material is exposed, and the both end edges are capable of being bent relative to the central portion around the longitudinal direction of the hinge portion as an axis, and have holes that penetrate in the front-to-back direction, i.e., the front and back.

[0008] In addition, the partition of the present invention is a partition formed by connecting multiple partition materials in the width direction, characterized in that the metal foils at the edge portions of adjacent partition materials in the width direction are arranged opposite each other and are connected by connecting members that penetrate the holes at the opposing edge portions. [Effects of the Invention]

[0009] The partition material of the present invention comprises a synthetic resin sheet material and metal foil laminated on the front and back of the sheet material, making it lightweight and strong.When in use, it can be folded at the hinge portion, and after use, the hinge portion can be returned to its original state so that the center and both end edges are almost flat, making the partition material easy to store.

[0010] Furthermore, according to the partition of the present invention, adjacent partition materials are connected by connecting members that pass through the holes in the edge portions, so the bending angle can be changed around the hinge portion as an axis, and therefore the angle between the central portions of adjacent partition materials can be changed as appropriate, so that by combining partition materials as appropriate, a space surrounded by partition materials can be created.

[0012] Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

[0013] In the drawings, 100 denotes a partition material, 12 denotes hinge portions formed at both ends of the partition material 100, and a partition 200 is formed by connecting the partition materials 100 according to the present invention.

[0014] 1 and 2 are explanatory diagrams of one embodiment of a partition material 100 according to the present invention, with Fig. 1 being a front view and Fig. 2 being a plan view. In this embodiment, the partition material 100 has a vertically elongated rectangular shape when viewed from the front, and includes a synthetic resin sheet material 10 and metal foils 11, 11 laminated on both the front and rear surfaces of the sheet material 10 in the thickness direction. In the drawings, unless otherwise specified, the left-right direction in Fig. 1 is referred to as the width direction, the up-down direction as the length direction, and the front-to-back direction as the thickness direction.

[0015] The partition material 100 has hinge portions 12, 12 at both left and right ends. The hinge portions 12 are formed continuously along the longitudinal direction of the partition material 100.

[0016] As a result, the partition material 100 has a central portion 13 having metal foil 11 on both sides in the thickness direction, hinge portions 12, 12 located on both side ends of the central portion 13, and edge portions 14, 14 located between the hinge portion 12 and the edge of the partition material 100. In other words, the hinge portions 12, 12 are located on both side ends of the central portion 13, and the edge portions 14 are located on either side of the hinge portion 12.

[0017] Fig. 3 is an enlarged view of the vicinity of the hinge portion 12 on the left side of Fig. 2. The hinge portion 12 does not have metal foils 11, 11 on either the front or rear surfaces, and the sheet material 10 is exposed.

[0018] In this embodiment, the sheet material 10 is a foamed polyethylene, so the partition material 100 can be folded around the longitudinal direction of the hinge portion 12 where the sheet material 10 is exposed in the thickness direction. This makes it possible to change the angle between the central portion 13 and the edge portion 14 around the hinge portion 12. In this embodiment, the thickness of the hinge portion 12 is the same as the thickness of the sheet material 10.

[0019] FIG. 4 is an enlarged vertical cross-sectional view of the vicinity of the hinge portion showing another embodiment of the partition material 100 according to the present invention, in which the thickness of the hinge portion 12 is thinner than the thickness of the sheet material 10.

[0020] The partition material 100 may be manufactured by using an extruder to form the sheet material 10 while adhering the metal foils 11, 11 to form an integral part, or by manufacturing the sheet material 10 and then adhering the metal foils 11, 11 to both thicknesswise surfaces of the sheet material 10. The hinge portion 12 may be formed by removing the metal foil 11 using a processing machine so that both thicknesswise surfaces of the sheet material 10 are exposed. In this case, a portion of the sheet material 10 that is adhered to the metal foil 11 may be removed together with the metal foil 11, so that the thickness of the hinge portion 12 is thinner than that of the sheet material 10, as shown in FIG. 4. The thickness of the hinge portion 12 may be set according to the required strength.

[0021] Next, a description will be given of a partition 200 formed by connecting a plurality of partition materials 100 together in the width direction. FIG.

[0022] The partition 200 of this embodiment is formed by connecting seven partition materials 100 in the width direction, with two partition materials 100 arranged on each side, forming a square in plan view. Only one partition material 100 is arranged on each side of the square, and the gap formed between both ends of the connected partition materials 100 forms an entrance / exit 30, forming an internal space 40 surrounded by the connected partition materials 100, with a door body 60 arranged at the entrance / exit 30.

[0023] Next, the connection structure between the partition materials 100 will be explained using Figures 6 to 8. Figure 6 is an enlarged view of the vicinity of the connecting member 50 in Figure 5, and Figure 7 is an explanatory view of the connecting member 50 in Figure 5, with (a) being a front view, (b) being a perspective view, and (c) being an exploded explanatory view. Figure 8 is an exploded explanatory view of Figure 6. In the partition 200, the partition materials 100 are connected to each other by the connecting member 50 at the end edges 14, 14 of adjacent partition materials 100.

[0024] 1 and 6, the edge portion 14 has holes 14a penetrating in the thickness direction. In this embodiment, the edge portion 14 has three holes 14a spaced apart in the longitudinal direction, but this can be set appropriately depending on the longitudinal dimension of the partition material 100.

[0025] The edge portions 14 of adjacent partition materials 100 are bent toward the interior space 30 around the hinge portion 12 as an axis, and are fastened together via connecting members 50 attached to holes 14a, 14a at corresponding heights in the edge portions 14, 14. This connects the partition materials 100 together.

[0026] In this embodiment, the connecting member 50 comprises a bolt 51, a nut 52, and a cap nut 53. The nut 52 is screwed onto a threaded portion 51a of the bolt 51, and the cap nut 53 is further screwed onto the tip of the threaded portion 51a. In other words, the nut 52 is movable between the head 51b of the bolt 51 and the cap nut 53 screwed onto the threaded portion 51a.

[0027] 8, hole 14a has a circular wide portion 14b in the center in the longitudinal direction and narrow portions 14c, 14c formed respectively above and below wide portion 14b in the longitudinal direction. Head 51b of bolt 51 can pass through wide portion 14b, while head 52a cannot pass through narrow portion 14c but threaded portion 51a can.

[0028] This allows the bolt 51 to be passed from the wide portion 14b of one hole portion 14a between the edge portions 14 to the wide portion 14b of the other hole portion 14a from the head 51b side, and then the threaded portion 51a can be moved downward along the narrow portion 14c and the nut 52 can be screwed into the head 51b side, thereby fastening the edge portions 14 between the head 51b and the nut 52. Furthermore, the nut 52 threaded onto the bolt 51 does not come off the threaded portion 51a due to the cap nut 53, so there is no risk of the nut 52 accidentally falling to the ground during work. In this embodiment, the holes 14a are formed on both the top and bottom of the edge portion 14, so even if the partition material 100 is used upside down, the partition materials 100 can be connected together using the same procedure as described above.

[0029] When the partition materials 100 are connected to each other, the connection angle can be changed by changing the angle between the edge portion 14 and the central portion 13.As shown in Figure 5, by setting the connection angle to 90 degrees or 180 degrees, it becomes possible to use seven connected partition materials 100 and arrange them in a square shape in a plan view, as in this embodiment, allowing evacuees and others to use the internal space 40 surrounded by the partition materials 100.

[0030] Here, it is sufficient that the partition material 100 can be bent around the hinge portion 12 as an axis, and therefore the sheet material 10 is preferably one that can deform when a load is applied. Therefore, the sheet material 10 may be made of an elastically deformable material such as rubber or elastomer, but when the connecting angle between the partition materials 100 is set to 90 degrees, the hinge portion 12 is in a state where the edge portion 14 is bent 135 degrees relative to the center portion 13. Therefore, if the sheet material 10 is made of rubber or elastomer, a large elastic repulsive force is generated when the sheet material 10 is bent, and the partition material 100, which is arranged in a square shape in plan view, may open up as it tries to return to its original state.

[0031] Therefore, when a foamed polyethylene is used as the sheet material 10 as in this embodiment, the repulsive force generated at the hinge portion 12 is relatively small even when the hinge portion 12 is bent. This makes it easier to maintain the state in which the partition materials 100 are connected to each other and arranged in a square shape in plan view, as shown in Figure 5.

[0032] The sheet material 10 may be made of a polyolefin synthetic resin such as polyethylene or polypropylene, or a copolymer using an α-olefin such as an ethylene-vinyl acetate copolymer.

[0033] As shown in Figure 3, the hinge portion 12 can be bent in either direction in the thickness direction because the sheet material 10 is exposed on both sides in the thickness direction. Therefore, when connecting partition materials 100 together, the hinge portion 12 can be used by bending it in the required direction as an axis.

[0034] Next, the entrance 30 of the partition 200 will be described. Fig. 9 is an explanatory diagram of the vicinity of the door body 60 in Fig. 5, and Fig. 10 is an explanatory diagram showing another state of use of the partition 200 in Fig. 5. A hook-and-loop fastener 61 is fixed in the vertical direction to the edge portion 14 of the partition material 100 to which the door body 60 is fixed. A hook-and-loop fastener 62 is also fixed in the longitudinal direction to one end of the door body 60. A wide hook-and-loop fastener 63 is then attached by engaging across the hook-and-loop fasteners 61, 62.

[0035] This allows the door body 60 connected to the partition material 100 to rotate around the hinge portion 12 as an axis. The other end of the door body 60 can overlap with the partition material 100 on the other end side of the entranceway, and the door body 60 can be switched between a state in which the door body 60 is closed to close the entranceway 30 as shown in FIG. 5 and a state in which the door body 60 is opened to allow passage through the entranceway 30 as shown in FIG. 9. Furthermore, there is no need to prepare a new hinge member for the door body 60, and the door body 60 can be opened and closed by utilizing the edge portion 14 of the partition material 100. The door body 60 can be removed from the partition 200 by removing the hook-and-loop fastener 63 from the hook-and-loop fasteners 61 and 62.

[0036] In this embodiment, the door body 60 is plate-shaped and comprises a synthetic resin sheet material and metal foil laminated on the front and back of the sheet material, and has a configuration similar to that of the partition material 100, but is not particularly limited thereto.

[0037] The partition 200 shown in Figures 5 to 10 is made by connecting seven partition materials 100 and arranging them in a square shape in a plan view, and is intended for use by evacuees in the internal space 40 surrounded by the partition materials 100.Depending on the size of the internal space 40 required and the number of evacuees, the partitions 200 can be combined to create multiple internal spaces.

[0038] Fig. 11 is a perspective view showing another embodiment of a partition 300 according to the present invention, in which two internal spaces 40 are formed by connected partition materials 100. In this embodiment, the partitions 200 shown in Fig. 5 are connected together. The partition materials 100 arranged between the two internal spaces 40 may be prepared separately for each internal space 40, or may be shared.

[0039] When they no longer need to be used as evacuation shelters, the partitions 200, 300 are disassembled, and the partition materials 100 and connecting members 50 are stored in a designated location. Since partition materials 100 of the same size can be used, storage is easy whether the partition materials 100 are stacked or placed vertically. If necessary, the partition materials 100 can be reassembled and used as partitions 200, 300.

[0040] Furthermore, the partition material 100 has a so-called sandwich structure consisting of metal foil 11, sheet material 10, and metal foil 11, and is therefore strong, so that the partition material 100 is unlikely to break or bend significantly when disassembling or storing the partitions 200, 300. Furthermore, if a foam is used as the sheet material 10, as in this embodiment, the weight can be reduced, making transportation and assembly even easier.

[0041] Although the partition 200 of the present invention has been described above based on the embodiments, the present invention is not limited to these embodiments. Various modifications that can be conceived by a person skilled in the art without departing from the gist of the present invention are also included within the scope of the present invention.
