[Figure 7] FIG. 2 is a bottom view of an application of the multi-function panel of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION
[0010] The multi-functional panel of the present invention functions as both a flooring material and a stretcher, and is characterized by having a recess and a flat portion on the side used as the flooring material, and a curved portion on the side used as the stretcher, with the center of the curved portion contacting the inner surface of the flat portion. The structure of the present invention will be described in detail below with reference to the drawings.
[0011] 1 and 2 show a preferred embodiment of the multi-function panel of the present invention. The description will be based on the state in which the first main surface of the multi-function panel is placed facing upward, with the shorter side facing forward when viewed from above. In this embodiment, for convenience, the side used as flooring is designated as the first main surface of the multi-function panel, and the side used as a stretcher is designated as the second main surface. However, the present invention is not limited to this. Also, FIG. 3(a) is a front view of the multi-function panel of this embodiment, and FIGS. 3(b) and 3(c) are cross-sectional end views of the A-A' and B-B' sections in FIGS. 1 and 2, respectively. Furthermore, FIG. 4(a) is a side view of the multi-function panel of this embodiment, and FIG. 4(b) is a cross-sectional end view of the C-C' section in FIGS. 1 and 2.
[0012] The multifunctional panel of this embodiment is manufactured by twin-sheet molding, which is a molding method in which two thermoplastic resin sheets are clamped together and heated to soften, then vacuum-molded and heat-sealed to form a hollow body. However, the manufacturing method for the multifunctional panel of the present invention is not limited to twin-sheet molding, as long as a hollow molded body of the desired shape can be obtained.
[0013] As shown in Figures 1 and 3, the first main surface of the multifunction panel of the present invention has recesses 14 at the four corners, and has a flat portion 12 with a flat surface in the area excluding the recesses 14. The recesses 14 are recessed toward the second main surface relative to the flat portion 12, and when the second main surface is used as a stretcher with the second main surface facing upward, the recesses 14 are used as a portion into which a hand can be inserted when lifting the multifunction panel. In this embodiment, the frame 11 is provided with a recess 11a recessed toward the second main surface to make it easier to insert a hand into the recess 14. The second main surface is provided with a protrusion 26 at a position corresponding to the recess 14 to support the recess 14.
[0014] In this embodiment, a plurality of grooves 13 are formed in a hexagonal pattern on the surface of the flat portion 12, and as shown in Figures 3(b) and (c), the bottoms of the grooves 13 protrude from the inner surface (the inner surface of the hollow molded body) and function as ribs. Therefore, the grooves 13 impart appropriate flexibility and strength to the flat portion 12. Note that the planar shape of the grooves 13 is not limited to the hexagonal pattern shown in Figure 1.
[0015] 2 to 4, the second main surface of the multifunction panel of the present invention has a curved portion 24 whose center is recessed toward the first main surface, and the curved portion 24 is curved in both the short and long directions of the multifunction panel. Therefore, when a person is placed on the multifunction panel with the second main surface facing upward, the person is accommodated in the curved portion 24, allowing for stable transportation. In this embodiment, the curved portion 24 is connected to the flat portion 23 in the left-right direction of FIG. 2, and when the multifunction panel is placed with the first main surface facing upward, the flat portion 23 comes into contact with the ground or floor to support the multifunction panel.
[0016] In the present invention, as shown in Figures 3(c) and 4(b), the inner surface of the central part of curved portion 24 is in contact with the inner surface of flat portion 12 of the first main surface, and has the function of holding flat portion 12 from below when placed with the first main surface facing upward, providing strength that makes flat portion 12 less likely to be dented even when a person or object is placed on it. Note that the dashed line in Figure 4(b) indicates the opening of recess 25 on the surface of curved portion 24.
[0017] Furthermore, in this embodiment, multiple recesses 25 are provided that are recessed toward the first main surface, and the inner surface of the bottom of each recess 25 contacts the inner surface of the first main surface, i.e., the inner surface of the flat portion 12 or the inner surface of the groove portion 13, thereby holding them in place, making it difficult for the flat portion 12 to be recessed even if a person or object stands on either side of the first main surface.
[0018] When multiple multi-function panels of the present invention are used side by side, they are preferably connected and fixed to one another. In this embodiment, a groove 15 is provided inside the frame 11 near the outer periphery of the first main surface. As shown in FIG. 5(a), the free end of a connecting member 31 with a generally U-shaped cross section, as shown in FIG. 5(b), is inserted into the grooves 15, 15 of two multi-function panels, allowing the connecting member 31 to span the frames 11 and connect the two multi-function panels. In this embodiment, a recess 23a recessed from the outer periphery toward the curved portion 24 is provided in the flat portion 23 of the second main surface. The flat portion 23 is surrounded by a groove 22 adjacent to the first main surface. Because the groove 22 is wider at the recess 23a, the area surrounded by the recess 23a, the groove 22, and the inner surface of the frame 21 is provided as a storage space for the connecting member 31. In this embodiment, six connecting members 31 can be stored in one multifunction panel.
[0019] Furthermore, as shown in Figure 6, the multi-function panel of this embodiment can provide privacy by inserting a flat partition 41 into the groove portion 15 on the first main surface, making it particularly useful when used as flooring in evacuation shelters.
[0020] The multifunction panels shown in Figures 1 and 2 have a rectangular planar shape, but by making it square as shown in Figure 7, it becomes possible to combine it with rectangular panels and arrange it in a way that makes it easier to adapt to the size of the space where it is placed. Figure 7 shows the second main surface of a square multifunction panel, in which the planar shape of the curved portion 24 is circular and multiple recesses 25 are arranged radially. The first main surface of such a multifunction panel has the same configuration as Figure 1, except that the length in the longitudinal direction of the area of the flat portion 12 of the rectangular multifunction panel shown in Figure 1 has been adjusted.
[0021] The multifunctional panel of the present invention is a hollow molded body made of synthetic resin, making it lightweight and easy to handle, including transportation, installation, and stacking. Furthermore, since it is easy to wash and dry even if it gets dirty, it can be used as flooring for outdoor events or placed on muddy areas to create a passageway. Furthermore, when used as a stretcher, there is a risk of blood or bodily fluids from the injured person becoming attached to it, but since it can be easily washed, it is easy to maintain its cleanliness.
[0022] Furthermore, because it is made of synthetic resin, it has high moisture resistance and weather resistance, and there is no risk of its performance deteriorating even with long-term storage. It also has a high degree of freedom in coloring, so you can freely choose the color depending on the application.
[0023] Furthermore, because it is a hollow molded body, it can be expected to have an insulating effect, reducing the heat in summer and the cold in winter in evacuation shelters, etc. In particular, by providing a curved portion on the second main surface side, when used as flooring, the area where the second main surface comes into contact with the floor is small, resulting in high thermal insulation between the floor and the material. Another advantage is that the curved portion on the second main surface makes it difficult for dirt and dust to get in due to people moving around.
[0024] The synthetic resin constituting the multifunctional panel of the present invention can be a recycled resin. Furthermore, if the multifunctional panel of the present invention is damaged, it can be recycled to make a new multifunctional panel. Furthermore, when an olefin-based resin is used, the resulting multifunctional panel has excellent durability, pressure resistance, chemical resistance, long-term storage resistance, high recyclability, and stackability.
[0025] The dimensions of the multifunctional panel of the present invention can be made to correspond to the dimensions of a typical tatami mat, making layout easier. For example, in the case of Edo-ma, a rectangular tatami mat is 1760 mm long, 880 mm wide, and 90 mm thick. Tatami dimensions vary depending on the type of tatami mat and the region in which it is used, so they can be selected appropriately depending on the region in which it is used. By making the dimensions correspond to tatami mats, it can be deployed in sizes such as 3 tatami mats, 6 tatami mats, and 8 tatami mats, and when combined with the square shape shown in Figure 7, it can also be used in sizes such as 4.5 tatami mats.
[0026] Furthermore, the multi-functional panel of the present invention may be configured such that the feel and appearance can be adjusted by attaching nonwoven fabric or woven cloth to the flat portion 12 of the first main surface, or by providing holes in the frame or the like so that ropes can be passed through the holes to secure the panel to the surrounding ground when used outdoors.
[0027] As described above, the multi-functional panel of the present invention functions as both a flooring material and a stretcher, but because it is easy to clean, it can also be used as a pet care area in evacuation shelters, etc. As described above, the multi-functional panel of the present invention can be provided in dimensions corresponding to a tatami mat, so that an area the size of, for example, half a tatami mat can be used as a care area by erecting partitions around it.
