[0003] [Patent Document 1] JP 2013-87613 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, although it may sound simple to cover the roof with blue tarps, the task is not simple.

[0005] A first problem to be solved by the present invention is to provide a sheet device that does not require a large area for storage.

[0006] A second problem to be solved by the present invention is to provide a seat device that can be easily folded for storage.

[0007] The third problem that the present invention aims to solve is to provide a seat device that is easy to use. It is to provide a seat device that allows easy unfolding (unfolding) of the folded seat. For example, it is to provide a seat device that allows easy unfolding and placing it over the roof.

[0008] A fourth problem to be solved by the present invention is to provide a seat device that allows easy installation (fixing) of a seat. For example, it is to provide a seat device that allows easy installation (fixing) of a seat covering a roof.

[0009] A fifth problem to be solved by the present invention is to provide a low-cost seat device. [Means for solving the problem]

[0010] The present invention relates to A sheet device comprising a flexible sheet and a plate body having a rigidity greater than that of the sheet, the plate body is provided integrally with the flexible sheet along an edge of the flexible sheet, The length of the plate in the longitudinal direction is shorter than the length of the flexible sheet at the edge A seat device is proposed.

[0011] The present invention proposes a sheet device in which the flexible sheet is preferably substantially rectangular in shape. For example, a sheet device in which the flexible sheet is rectangular in shape is proposed. For example, a sheet device in which the flexible sheet is square in shape is proposed.

[0012] The present invention proposes a sheet device in which the plate body is provided along opposing sides of the substantially rectangular flexible sheet. When the flexible sheet is rectangular, the plate body is provided along the long sides of the flexible sheet. The plate body is preferably provided along the two long sides of the flexible sheet, but may be provided along the two short sides. Of course, the plate body may be provided along the four sides. When the flexible sheet is square, the plate body is provided in the same manner as in the rectangular case.

[0013] The present invention proposes a sheet device in which there are two or more plates provided along the edge of the flexible sheet, and there is a gap between the plates. It is more preferable to have two or more plates than one. In this case, it is preferable that the plates are provided so as to have a gap. In short, it is more preferable that the plates are provided so as to be discontinuous, rather than being provided so as to be connected.

[0014] The present invention proposes a seat device in which the plate body is provided so that the plate body is spaced apart when the flexible sheet is folded. When the flexible sheet of the seat device is foldable, the space (horizontal area) required for storage is small. The seat device is used as an emergency measure when a roof is damaged by a typhoon or heavy rain, for example. Of course, this is not limited to this case. Therefore, for example, a local government may prepare it as a crisis measure (disaster prevention measure). Of course, it may also be prepared by an individual. In such a case, it is very convenient that the storage space is small. In order to make the seat device foldable, it is necessary to avoid the plate body being provided on the folding line when the flexible sheet is folded. If folding is the only consideration, it is sufficient that the plate body is cut on the folding line. However, in this case, when the folded seat device is unfolded, the unfolding workability is poor. If the plates are provided at intervals, i.e., if a plate is provided every other plate when the flexible sheet is folded, the workability of unfolding (deploying) the folded sheet device is good when unfolding (deploying) it, because the sections where no plate is provided have high flexibility when unfolding (deploying) the folded sheet device.

[0015] The present invention proposes a sheet device as described above, in which the plate body is provided so that the flexible sheet can be folded in an odd number of times.

[0016] The present invention proposes a sheet device as described above, in which the plate body is not provided at a corner of the flexible sheet.

[0017] The present invention proposes the sheet device, wherein the plate is provided near a corner of the flexible sheet.

[0018] The present invention proposes a sheet device in which strings are provided at the corners of the flexible sheet. The flexible sheet is unfolded by pulling the strings. This provides good unfolding workability.

[0019] The present invention proposes a seat device, in which the plate has a thickness of 2 mm or more. The plate improves the workability when folding and unfolding the seat device. However, this is not the only effect. For example, the plate can be fixed by nailing (rivet). This effect can also be achieved. When fixed by nailing (rivet), the thickness of the plate does not matter. However, even if not nailed, the seat device has a step of 2 mm or more at the plate. Therefore, the seat device can be prevented from being blown away by the wind just by placing a heavy object at the step (so as to straddle the part inside the plate).

[0020] The present invention proposes a seat device as described above, wherein the plate body has unevenness on its edge. Effect of the Invention

[0021] Since it can be folded, it does not require a large storage area and is easy to store.

[0022] It is easy to fold for storage.

[0023] The operation of use is simple. The operation of unfolding (unfolding) the folded sheet is simple. For example, the operation of putting it on a roof is simple.

[0024] Installation (fixing) of the sheet is easy. For example, installation (fixing) of the sheet covering the roof is easy.

[0025] The cost is low. [Brief description of the drawings]

[0027] The present invention is a sheet device. The sheet device is used, for example, to cover a roof. It is used to cover a damaged roof to prevent rainwater leaking. Of course, this is not limited to this. For example, the sheet device can be placed on the ground and unfolded (spread out) to be used for cherry blossom viewing. The device includes a flexible sheet. The sheet is, for example, a sheet called a blue sheet. Of course, this is not limited to this. The thickness of the sheet is, for example, about 0.1 to 1 mm. It may be thicker than the numerical value. It may be thinner. The material is generally a water-resistant resin material. However, it is not limited to resin. In some cases, it may not be water-resistant. The "flexible" of the flexible sheet means that the sheet is foldable. The device includes a plate. The rigidity of the plate is greater than the rigidity of the sheet. The plate with greater rigidity (the plate provided along the edge of the sheet) improves the workability when folding and unfolding the sheet. Furthermore, for example, the sheet can be fixed by nailing (studs) the plate portion. When nailed (studs) are driven, the flexible sheet is reliably pressed by the plate. That is, the flexible sheet is attached in close contact. Even if not nailed, if there is a step at the plate portion, the sheet device can be prevented from being blown away by wind by simply placing a heavy object across the step. The thickness of the plate is, for example, 2 mm or more. There is no particular restriction on the upper limit, but 1 cm would be sufficient. The plate is, for example, approximately rectangular. If the edge of the plate is uneven (jagged), when a heavy object is placed across the step, the heavy object will get caught on the unevenness (jagged), making it difficult for the heavy object to be blown away. Therefore, it is preferable that the edge is uneven (especially jagged with an acute angle). The shape of the jagged edges may be triangular, trapezoidal, or rectangular. The width of the plate is, for example, 2 cm or more. Preferably, it is 3 cm or more. More preferably, it is 4 cm or more. For example, it is 10 cm or less. Preferably, it is 9 cm or less. More preferably, it is 8 cm or less. The length of the plate in the longitudinal direction is shorter than the length at the edge of the flexible sheet.The length of the plate is preferably determined by the size of the folded flexible sheet. The length is preferably about 85 to 99% of the dimension of one folded section. It may be 100%. The dimension of one folded section is, for example, about 30 to 50 cm. If the dimension of one section is, for example, 35 cm, the length of the plate is shorter than this, for example, about 30 cm or more and less than 35 cm. The plate is integrally provided to the flexible sheet along the edge of the flexible sheet. Here, along the edge is not limited to the case where the edge of the plate and the edge of the flexible sheet are the same. It means that the edge of the plate may be inside the edge of the flexible sheet (for example, about 1 to 2 cm inside). The term "integrally provided" is not limited to the case where an adhesive is applied to the entire surface of one surface (main surface) of the plate and the entire surface of the plate is bonded to the flexible sheet by this adhesive. For example, the plate may only be bonded in spots. The bonding may be replaced by welding. Alternatively, the plate may be attached to the flexible sheet by sewing it, or other means may be used.

[0028] The flexible sheet is, for example, substantially quadrangular. Preferably, it is substantially rectangular. For example, it is rectangular. For example, it is square. It may be rhombic. It may be triangular. It may be any other shape. However, it is preferably substantially quadrangular, particularly substantially rectangular, and more preferably substantially rectangular.

[0029] When the flexible sheet is substantially rectangular, the plate body is preferably provided along two opposing sides of the substantially rectangular flexible sheet. The plate body may be provided along only one side of the substantially rectangular flexible sheet. However, it is preferable that the plate body is provided along two opposing sides. When the flexible sheet is rectangular, the plate body is preferably provided along the two long sides of the flexible sheet. Of course, the plate body may be provided along two short sides. It is preferable that the plate body is provided along all four sides.

[0030] It is preferable that there are two or more plates provided along the edge of the flexible sheet. When there are two or more plates, it is preferable that there is a gap between the plates. It is preferable that the plates are provided so that they are located in every other section when the flexible sheet is folded. If the flexible sheet is foldable, the space (area on a horizontal plane) required for storing the sheet device is small. In order to make it possible for the sheet device to be folded, the plates do not exist on the folding line when the flexible sheet is folded. If folding is the only consideration, it is sufficient that the plates are cut (discontinuous) on the folding line. However, in this case, when the folded sheet device is unfolded, the unfolding workability is poor. If the plates are provided so that they are located in every other section, that is, if the plates are provided in every other section when the flexible sheet is folded, the unfolding workability is good when unfolding the folded sheet device. This is because when the folded sheet device is unfolded, the sections where the plate body is not provided have high flexibility (bending ability). It is preferable that the plate body is provided so that the flexible sheet can be folded in an odd number of times. This is because the workability is good when unfolding (unfolding) the flexible sheet. However, this does not exclude cases where the flexible sheet can be folded in an even number of times.

[0031] It is preferable that strings are provided at the corners of the flexible sheet, particularly at the four corners. By pulling the strings, the folded flexible sheet can be unfolded. The unfolding workability is good. In particular, when the flexible sheet is folded in an odd number of folds, the unfolding workability is good.

[0032] The plate is also provided near the corners of the flexible sheet. The plate is not provided at the corners of the flexible sheet. Preferably, the plate is not provided at the corners of the flexible sheet.

[0033] It is preferable that a recess (or groove) is formed on the surface (main surface) of the plate. When nails are driven in the position of the recess (or groove), adhesion is improved. The recess (or groove) acts as a guide for driving the nails, making the nailing work easier.

[0034] The flexible sheet is not provided with a plate (rigid plate) having the same length as one side of the flexible sheet. This is because, in this case, the flexible sheet cannot be folded into a small size. In order to fold a flexible sheet provided with a plate, the plate must not be on the folding line at least. As described above, it is preferable that the plate is provided at intervals. When a sheet device provided with plates at intervals is, for example, spread out (deployed) on a roof and fixed by nailing, gaps are likely to be formed at the edge where the plate is not provided. However, this is the case when the sheet device is arranged so that the plate is below the flexible sheet. In such a case, if a flexible material plate, for example, a sponge plate, is provided between the plates, gaps are unlikely to be formed. Even if the flexible material plate (for example, a sponge plate) is provided, there will be no significant hindrance when folding or spreading the sheet. When the plate is arranged to be above the flexible sheet, there is no such risk. The plate can be wrapped with the flexible sheet. When the plate is wrapped with the flexible sheet, the thickness of the wrapped area increases. In other words, the flexible sheet overlaps several times. In the area where the sheet overlaps several times, it is possible to fix the sheet by nailing even without the plate. The plate makes the wrapping easier.

[0035] The present invention will be described below with reference to specific examples, but the present invention is not limited to the following examples.

[0036] FIG. 1 is a plan view of a seat device of a first embodiment of the present invention in an unfolded (deployed) state, FIG. 2 is a plan view after the first stage of folding, and FIG. 3 is a plan view after the second stage of folding (after all folding has been completed).

[0037] In each figure, 1 is a sheet device, 2 is a flexible sheet, and 3 is a plate body.

[0038] The sheet device 1 (flexible sheet 2) is rectangular in shape in the unfolded state (see FIG. 1). If the length of one side of one section (the boundary of the section is shown by a dashed line) when the flexible sheet 2 is folded is about 37 cm, the flexible sheet 2 has a long side length of about (2n+1:n is an integer)×37 cm and a short side length of about (2k+1:k is an integer smaller than n)×37 cm. The flexible sheet 2 may have a long side length of about (2n:n is an integer)×37 cm and a short side length of about (2k:k is an integer smaller than n)×37 cm. However, in this embodiment, a case where odd-numbered folding is possible will be described. For example, the long side length is about 9×37 cm (about 333 cm). The short side length is about 7×37 cm (about 259 cm).

[0039] Plates 3 are approximately 36.5 cm long, 4.5 cm wide, and 4 mm thick. Plates 3 are adhered along the long edge of flexible sheet 2. A total of eight plates 3 (four on one side, eight on two sides) are provided so that when flexible sheet 2 is folded into nine pieces in the longitudinal direction, there are no plates at every other folded section and no plates at either end (see FIG. 1).

[0040] Numerals 4 denote rings provided at the four corners of the flexible sheet 2. A string 5 is attached to each of the rings 4.

[0041] The sheet device 1 is folded in an odd number of folds during storage (see FIG. 3). The sheet device 1 is folded in a W shape. The sheet device 1 is folded in the same way as a folding screen is folded. The flexible sheet 2 in the unfolded state shown in FIG. 1 is first folded so that creases are formed along (parallel to) the short sides of the flexible sheet 2. This folding is performed in a W shape. This results in a strip (folded body after the first folding step) with a width of about 37 cm and a length of about 7×37 cm (about 259 cm) (see FIG. 2). This strip is folded so that creases are formed along (parallel to) the short sides of the strip. This folding is also performed in a W shape. This results in a folded body of the flexible sheet 2 (each section is about 37 cm×about 37 cm in size) (see FIG. 3). Since the plate body 3 is not arranged so as to straddle adjacent folding sections (it is not arranged on the planned fold line (the dashed dotted line)), there is no problem when folding the flexible sheet 2.

[0042] To unfold (spread) the flexible sheet 2 from the folded state shown in Fig. 3 to the state shown in Fig. 1, all that is required is to pull the string 5 in the diagonal extension direction. It can be unfolded (spread) very easily. For example, it is easy to unfold the flexible sheet 2 even on a roof. The flexible sheet 2 spread out on the roof can be fixed by nailing the three plates, or it can be fixed simply by placing sandbags on the three plates.

[0043] FIG. 4 is a plan view of a seat device according to a second embodiment of the present invention in an unfolded (deployed) state. In the second embodiment, the plate body 3 is provided along the four sides of the flexible sheet 2. In the second embodiment, the plate body 3 is also provided so that when the flexible sheet 2 is folded, the plate body 3 is provided at every other folding section and is not present at both ends (see FIG. 4). As the rest is similar to the sheet device of the first embodiment, detailed description will be omitted.

[0044] FIG. 5 is a plan view of a seat device according to a third embodiment of the present invention in an unfolded (deployed) state. The sheet device of the third embodiment differs from the sheet device of the first embodiment in the number of plate bodies 3. In this embodiment, plate bodies 3 are provided in all compartments along the long sides of the compartments (compartments created when the flexible sheet 2 is folded). In this case, however, the length is made shorter than that of the plate bodies 3 of the first embodiment. The plate body 3 of the sheet device of the third embodiment is approximately 35 cm long, approximately 4.5 cm wide, and approximately 4 mm thick. This allows the flexible sheet 2 to be folded. As other points are similar to those of the sheet device of the first embodiment, detailed explanations will be omitted. However, when the folded seat device of the third embodiment is opened (deployed), the operability of the flexible sheet 2 (opening (deployment) operability) is inferior to that of the seat device of the first embodiment.

[0045] FIG. 6 is a plan view of a seat device according to a fourth embodiment of the present invention in an unfolded (deployed) state. The seat device of the fourth embodiment differs from the seat device of the first embodiment only in the arrangement position of the plate body 3. That is, a total of 10 plate bodies 3 (a total of 5 on one side, a total of 10 on two sides) are provided at every other section from the end (see FIG. 6). As the rest is similar to the seat device of the first embodiment, detailed description will be omitted. Incidentally, the plate body 3 is usually made of a material that is highly rigid (difficult to bend). For this reason, if the plate body 3 is provided as in the third or fourth embodiment, the short side of the flexible sheet 2 cannot be rolled (wound and overlapped). There are cases where it is preferable to roll (wrap and overlap) the short side of the flexible sheet 2. For example, when it is rolled (wrapped), the thickness increases at that point. This increases the strength. This part can be attached to the plate material on the bottom with a rivet or the like. This makes it difficult for wind and rain to get in. Therefore, it was preferable for the plate body 3 to be provided as in the first or second embodiment. [Explanation of symbols]
