Description

Technical Field

[0001] The present invention relates to a tent that can be quickly and easily assembled during use and can be quickly and easily wound up or folded into a small volume state when not in use.

Background Art

[0002] Conventionally, many types of assembled tents such as pop-up tents and one-pole tents are known.

Summary of the Invention

Problems to be Solved by the Invention

[0003] However, all of the many types of conventional tents have taken a long time for assembly, disassembly, and storage work. In addition, a pop-up tent requires a certain technique for folding the wire during disassembly and storage, which may cause difficulties in disassembly and storage for those who are not familiar with it. Further, in the case of a one-pole tent, since the support penetrates the interior of the tent after assembly, the habitability may be inferior.

Means for Solving the Problems

[0004] The tent according to the present invention is a hollow N-sided pyramidal tent formed by an N-sided (N is an integer of 3 or more) base and N triangular sides, wherein one of the N sides forming the base is connected and fixed to one side of one of the N triangles, and the other (N-1) sides forming the base are fitted with openable and closable fasteners, and when the fasteners are not closed before the tent is assembled, the other (N-1) sides forming the base are not connected and fixed anywhere except by the fasteners, and among the N triangles, the 1st to the Nth triangles are connected and fixed to each other by their adjacent sides, and when the tent is assembled the Nth triangle The sides to which the first triangle is connected and fixed, and the sides to which the other (N-1) sides forming the base of the triangles other than the one connected and fixed to one of the N sides forming the base are connected and fixed only by the fasteners attached, and as a whole, the base and the N triangles are connected and fixed to form a single sheet on a flat plane. When assembling the tent, the other (N-1) sides forming the base and the sides of the triangles connected to those (N-1) sides are closed and connected with the fasteners, and the adjacent sides of the Nth triangle and the first triangle are closed and connected with fasteners to form the hollow N pyramidal tent. With this configuration, the tent can be assembled into a tent shape quickly and easily when in use. Also, when not in use, the tent can be quickly and easily rolled up or folded into a small volume. In addition, since the support poles do not penetrate into the interior of the tent after assembly, the livability is improved.

[0005] Furthermore, the tent may be characterized in that one support post is attached to each of the N sides of the hollow N-pyramid shape. [Effects of the Invention]

[0006] The tent according to the present invention can be assembled into a tent shape quickly and easily when in use. Furthermore, when not in use, the tent can be quickly and easily rolled up or folded into a compact size. Additionally, since the support poles do not penetrate the interior of the tent after assembly, livability is improved. [Brief explanation of the drawing]

[0008] The tent according to the present invention will be described in detail below with reference to the drawings. In the description of the drawings, the same elements will be denoted by the same reference numerals, and redundant explanations will be omitted.

[0009] [First Embodiment] FIG. 1 is a plan view of a tent 10 according to the first embodiment. As shown in FIG. 1, the tent 10 of the present case includes a sheet 11, three support columns 12, 13, 14 that stretch it into a predetermined shape, and fasteners 15, 16 that join opposite sides. Note that this embodiment corresponds to the case where N in the N-sided polygon in the present invention is 3, and corresponds to a tent having a hollow triangular pyramid shape formed by a triangular bottom surface and three triangular side surfaces. Further, N is not limited to 3 and can be an integer of 3 or more. In embodiments other than this embodiment, an example of an embodiment where N is other than 3 will be described in detail. This sheet 11 has a triangular bottom surface 17 and three triangular side surfaces 18, 19, 20 connected and fixed, and exhibits a hollow triangular pyramid shape when assembled. The support columns 12, 13, 14 are arranged radially at locations on the sides of the triangular side surfaces around the vertex 23 and are fixed to the sheet 11. The support columns 12, 13, 14 may be adhered to the sheet or may be fixed by an instrument so as to be detachable. The support columns may be fixed to either the inner or outer surface of the tent sheet when the tent is assembled. The fastener 15 includes a slider 21, and a lower stop is located near the vertex 23 of the triangular side surfaces 18, 19, 20. It is desirable that the slider be of a type that can be operated from both the front and back (the same applies to the following fasteners). One element tape of the fastener 15 extends over the side of the triangular side surface 18, and an upper stop is located near the vertex 24. The other element tape of the fastener 15 extends over the side of the triangular side surface 20, and an upper stop is located near the vertex 25. The fastener 16 includes a slider 22, and a lower stop is located near the vertex 28. One element tape of the fastener 16 extends over the side of the bottom surface 17, and an upper stop is located near the vertex 24 via the vertex 26. The other element tape of the fastener 16 extends over the sides of the triangular side surfaces 19, 20, and an upper stop is located near the vertex 25 via the vertex 27.

[0010] Windows may be formed in the triangular side surfaces 18, 19, 20 (FIG. 2, 31). The bottom surface 17 may be provided with a detachable notch (FIG. 2, 32) or the like for using a stove or having a bonfire inside the tent.

[0011] In addition to chemical fiber cloth, the sheet 11 may also be made of canvas, vinyl, non-woven fabric, waterproof paper, etc. The columns 12, 13, and 14 are fixed to the sheet, but the columns can move independently of each other. They may be connected to each other using movable metal fittings or the like. The columns 12, 13, and 14 may be pipes or polygonal columns made of metal, resin, waterproof paper, etc., or may be wires or balloons. A bag portion may be provided on the sheet 11, and the columns may be fixed to the sheet in a detachable manner by inserting the columns. The sheet 11 may have a shape with appropriately rounded corners at the bottom surface and the corners of the triangular side surfaces so that the element tape of the fastener is not overly burdened. Also, an appropriate slack (margin) may be provided for the element tape of the fastener at the same portion. The fastener preferably has a water-stopping function to prevent rainwater from entering. The fastener may be of other types as long as it can continuously connect the sides of the sheet 11, such as a surface fastener or an adhesive tape.

[0012] During assembly, the user folds the sheet 11 along the sides of the triangular side surfaces and the bottom surface so that the vertex 27 overlaps the vertex 26 and the vertex 25 overlaps the vertex 24. The tent is assembled by the columns 12, 13, and 14, and the tent 10 becomes a triangular pyramid shape (Figure 3). The user moves the slider 22 of the fastener 16 from a position near the vertex 28 which is the lower stop, through the vertices 26 and 27, to a position near the vertices 24 and 25 to close the fastener. A joint or fitting portion for fixing the column 14 to the bottom surface 17 may be provided at the vertex 26. The user moves the slider 21 of the fastener 15 from a position near the vertex 23 which is the lower stop, to a position near the vertices 24 and 25 to close the fastener. Thus, the assembly is completed.

[0013] Figure 3 is a perspective view of the assembled tent 10. The triangular side surface 20 also serves as an entrance / exit, and by operating the sliders 21 and 22 of the fasteners 15 and 16, the triangular side surface 20 can be opened and closed to enter and exit the tent 10.

[0014] When the tent is finished to be used, dismantled, and stored, the user opens all zippers 15 and 16 and unfolds the tent 10. With the tent unfolded, as shown in Figure 4, the bottom surface 17 is folded in the direction of the triangular side surface 18, and the triangular side surface 20 is folded in the direction of the triangular side surface 19. Once folded, as shown in Figure 5, the support poles 14, 13, and 12 are bundled together starting from the vertex 23, and the triangular side surface 20 Roll up sections 19, 18 and the bottom 17. After rolling up, the tent 10 will be in the shape of a thin cone (Figure 6).

[0015] Alternatively, when dismantling and storing the tent, after folding the base 17 and triangular sides 20, the triangular sides 20, 19, 18 and the base 17 may be folded using a line extending radially from the vertex 23 as a fold line, as shown in Figure 7. By folding the tent multiple times using a line extending radially from the vertex 23 as a fold line, the tent 10 becomes a thin, segmented shape. Alternatively, after folding the base 17 and triangular sides 20, the support poles 14, 13, 12 may be bundled together starting from the vertex 23, and the sheet 11 may be twisted as if folding an umbrella into a thin shape to form a rod shape.

[0016] In the first embodiment, in the embodiment shown in Figure 1, the base 17 and triangular sides 18, 19, and 20 were equilateral triangles, but they can be modified depending on the application. Figure 8 is a plan view of the tent 101 when unfolded, in which the length of the support column 131 that supports the area between vertices 231 and 281 is longer than in the example in Figure 1. Because the support column 131 is longer, the triangular sides 181 and 191 are larger than in the example in Figure 1, and when assembled, vertex 231 is closer to the front of the tent (the line connecting vertices 241 and 261 of the base 171, i.e., the surface of the triangular side 201) (Figure 9). By adopting such a structure, it is also possible to reduce the intrusion of rain when opening and closing the entrance (triangular side 201) during rainfall.

[0017] [Second Embodiment] Figure 10 is a plan view of a tent 40 according to a second embodiment. As shown in Figure 10, the tent 40 of the second embodiment has a sheet 41, four support poles 42, 43, 44, and 45 for stretching it into a predetermined shape, and fasteners 46 and 47 for joining opposing sides. This embodiment corresponds to the case where N is 4 in the N-sided polygon of the present invention, and corresponds to a hollow square pyramidal tent formed by a square base and four triangular sides. The sheet 41 has a square base 48 and four triangular sides 49, 50, 51, and 52 connected and fixed, and when assembled it takes the shape of a hollow square pyramidal pyramid. The support poles 42, 43, 44, and 45 are arranged radially around the vertex 63, at the edges of the triangular sides, and are fixed to the sheet 41. The support poles 42, 43, 44, and 45 may be glued to the sheet, or they may be fixed with devices so that they can be attached and detached. Zipper 46 has a slider 61, with a bottom stop located near vertex 63 on the triangular sides 49, 50, 51, and 52. A slider that can be operated from both the front and back is preferable (the same applies to the following zippers). One element tape of zipper 46 extends along the edge of triangular side 49, with a top stop located near vertex 64. The other element tape of zipper 46 extends along the edge of triangular side 52, with a top stop located near vertex 65. Zipper 47 has a slider 62, with a bottom stop located near vertex 66. One element tape of zipper 47 extends along the edge of the base 48, passing through vertices 67 and 68, with a top stop located near vertex 64. The other element tape of zipper 16 extends along the edges of triangular sides 50, 51, and 52, passing through vertices 69 and 70, with a top stop located near vertex 65.

[0018] During assembly, the user folds the sheet 41 along the sides and base of the triangle so that vertex 69 overlaps vertex 67, vertex 70 overlaps vertex 68, and vertex 65 overlaps vertex 64. The tent is assembled using the support poles 42, 43, 44, and 45, and the tent 40 becomes a square pyramidal shape. The user moves the slider 61 of the zipper 46 from a position near vertex 66, which is the bottom stop, through vertices 67, 69, vertices 68, 70, to the position of vertices 64, 65, and closes the zipper. Joints or fittings may be provided at vertices 67 and 68 to secure the support poles 44, 45 to the base 48. The user moves the slider 61 of the zipper 15 from a position near vertex 63, which is the bottom stop, to the position of vertices 64, 65, and closes the zipper. Assembly is now complete.

[0019] Figure 11 is a perspective view of the assembled tent 40. The triangular side 52 also serves as an entrance. By operating the sliders 61 and 62 of zippers 46 and 47, the triangular side 52 can be opened and closed, allowing entry and exit from the tent 40. To make the opening larger, zipper 47 can be opened to the vertices 69 and 67, and both triangular sides 52 and 51 can be opened.

[0020] When the tent is finished to be used, dismantled, and stored, the user opens all zippers 46 and 47 and unfolds the tent 40. With the tent unfolded, the bottom surface 48 is folded in the direction of the triangular side surface 49 and the triangular side surface 52 in the direction of the triangular side surface 51, as shown in Figure 12. Once folded, as shown in Figure 13, the triangular side surfaces 52, 51, 50, 49 and the bottom surface 48 are rolled up, starting from the vertex 63 and bundling the support poles 45, 44, 43, and 42 together. After rolling up, the tent 40 will be in the shape of a thin cone (Figure 14).

[0021] Alternatively, when dismantling and storing the tent, after folding the base 48 and triangular sides 52, the triangular sides 52, 51, 50, 49 and the base 48 may be folded using a line extending radially from the vertex 63 as a fold line, as shown in Figure 15. By folding the tent multiple times using a line extending radially from the vertex 63 as a fold line, the tent 40 becomes a thin circular section. Alternatively, after folding the base 48 and triangular sides 52, the support poles 45, 44, 43, 42 may be bundled together starting from the vertex 63, and the sheet 41 may be twisted as if folding an umbrella into a thin shape to form a rod.

[0022] In each embodiment, if the support poles are made of a highly flexible material such as wire, the tent 10, which is folded into a long, conical shape, can be further rolled into a circular shape or bent to make it more suitable for transport. Also, if the support poles are provided with tenons, threads, etc., allowing them to be divided and reassembled into multiple parts, the tent 10, which is folded into a long, conical shape, can be further bent to make it more suitable for transport.

[0023] This tent, even when deployed, has its support poles arranged radially from a central point, allowing it to be folded or rotated to create a small, elongated cone or circular section shape, making storage and transport easy. Furthermore, since all of its components can be integrated, there is little risk of losing or forgetting parts. When disassembled, all sides and the bottom of the tent can be formed from a single flat surface, and its simple structure allows for low manufacturing costs. Due to its clear structure, even first-time users can easily assemble the tent. The assembly process is also simple, requiring only closing the zipper slider from the bottom stop to the top stop along the element tape, allowing users to assemble the tent quickly and easily. Due to its structure, the tent can have a large opening (one side of the triangular pyramid in the first embodiment, and one or two sides of the square pyramid in the second embodiment), making it easy to put in and take out items stored inside, and suitable for uses such as temporary storage of construction materials. Because the manufacturing cost of this tent can be kept low, it is possible to make it a disposable, simple tent by using paper pipes for the support poles, waterproof paper for the sheet, and hook-and-loop fasteners (or a combination of adhesive tape and hook-and-loop fasteners) for the fasteners. Unlike existing disposable tents made of cardboard, it does not need to be transported in a flat state, and the tent can be rolled up or folded into a small size, making it easy to transport.

[0024] This tent has a structure that allows it to be rolled up or folded into a cone shape by arranging support poles radially around one vertex (vertex 23 in the first embodiment, vertex 63 in the second embodiment). As a result, a relatively large load is placed on the central vertex during assembly, disassembly, and storage, which may make that part more susceptible to damage.

[0025] Therefore, as shown in Figure 16, a folded portion 33 may be provided in the sheet 11 near the vertex 23 which is the center point of the support pole of the tent 10 in the first embodiment. The sheet is folded back towards the support column at the central vertex and glued in a way that wraps around the support column (Figure 17). This increases the contact area between the sheet and the support column, and also increases the thickness of the sheet in the load-bearing area, thus preventing damage to that part. Similar folded sections can also be provided near the vertex 63 of tent 40 in the second embodiment, the vertex 102 of tent 91 in the third embodiment, the vertex 112 of tent 40 in the fourth embodiment, and the vertex 122 of tent 92 in the fifth embodiment.

[0026] To prevent rainwater from entering through the zippers during tent assembly, and to prevent excessive force from being applied to the zippers during tent assembly, an overhang 34 may be provided around the bottom surface 17 of the tent, as shown in Figure 18, and an additional zipper 48 may be provided at the end of the overhang 34, creating a double zipper connecting the sides and the bottom surface. One element tape of the zipper 48 is located at the end of the overhang 34, and the other element tape is located on the triangular side surface 19, which is the outer surface during assembly. The bottom stopper of the zipper 48 is detachable, and it is preferable that the slider 71 be of a type that can be operated from both the front and back. When assembled, the overhang 34 rises above the bottom surface 17 and covers a part of the side of the tent (Figure 19), thus preventing rainwater from entering, and the strength of the tent is increased because the side with the overhang has a double zipper. If the slider is of a type that can be operated from both the front and back, an overhang can also be provided on the bottom surface 17, in the part opposite the triangular side surface 20 which also serves as the entrance to the tent. Similar overhangs can also be provided around the bottom surface 48 of the tent 40 in the second embodiment, the bottom surface 17 of the tent 91 in the third embodiment, the bottom surface 48 of the tent 40 in the fourth embodiment, and the bottom surface 48 of the tent 92 in the fifth embodiment.

[0027] [Third Embodiment] The tent that forms a triangular pyramidal shape when assembled, as shown in the first embodiment, can also be realized with a sheet 95 having the shape shown in Figure 20. Figure 20 is a plan view of the tent 90 according to the third embodiment. As shown in Figure 20, the sheet 95 has three support poles 12, 13, and 14 that stretch it into a predetermined shape, and fasteners 15, 81, and 82 that join opposite sides. This embodiment corresponds to the case where N in the N-sided polygon of the present invention is 3, and corresponds to a hollow triangular pyramidal tent formed by a triangular base and three triangular sides. In this sheet 95, the triangular base 17 and the three triangular sides 18, 19, and 20 are connected and fixed, and when assembled it takes the shape of a hollow triangular pyramidal shape. The support poles 12, 13, and 14 are arranged radially around the vertex 102, at the edges of the triangular sides, and are fixed to the sheet 95. The support poles 12, 13, and 14 may be glued to the sheet, or they may be fixed with devices so that they can be attached and detached. The support poles may be fixed to either the inner or outer surface of the tent sheet when the tent is assembled. Zipper 15 has a slider 21, with a bottom stop located near the vertex 102 of the triangular sides 18, 19, and 20. A slider that can be operated from both the front and back is preferable (the same applies to the following zippers). One element tape of zipper 15 extends along the edge of the triangular side 18, with a top stop located near the vertex 101. The other element tape of zipper 15 extends along the edge of the triangular side 20, with a top stop located near the vertex 103. Zipper 81 has a slider 72, with a bottom stop located near the vertex 106 of the triangular sides 18, 19, and the base 17. One element tape of zipper 81 extends along the edge of the triangular side 18, with a top stop located near the vertex 101. The other element tape of zipper 81 extends along the edge of the base 17, with a top stop located near the vertex 105. The zipper 82 is equipped with a slider 73, and its bottom stop is located near the vertex 104 of the triangular sides 20, 19, and base 17. One element tape of the zipper 82 extends along the edge of the triangular side 20, and its top stop is located near the vertex 103. The other element tape of the zipper 82 extends along the edge of the base 17, and its top stop is located near the vertex 105.

[0028] Similar to the first embodiment, when assembling the tent, the user folds the sheet 95 along the connected and fixed edges of the triangular sides and bottom, and closes the zippers 15, 81, and 82 to form a triangular pyramid. The tent is assembled in this manner. When dismantling, the tent is taken apart by opening each zipper. The dismantled tent is stored in a small volume, such as a thin cone, section, or rod shape, by rolling up or folding it while bundling the support poles, as in the first embodiment.

[0029] [Fourth Embodiment] The tent that forms a square pyramidal shape when assembled, as shown in the second embodiment, can also be realized with a sheet of the shape shown in Figure 21. Figure 21 is a plan view of the tent 91 according to the fourth embodiment. As shown in Figure 21, the tent 91 of the fourth embodiment has a sheet 96, four support poles 42, 43, 44, and 45 that stretch it into a predetermined shape, and fasteners 46, 83, and 84 that join opposite sides. This embodiment corresponds to the case where N in the N-sided polygon of the present invention is 4, and corresponds to a hollow square pyramidal tent formed by a square base and four triangular sides. The sheet 96 has a square base 48 and four triangular sides 49, 50, 51, and 52 that are connected and fixed, and when assembled it takes on the shape of a hollow square pyramidal shape. The support poles 42, 43, 44, and 45 are arranged radially around the vertex 112, at the edges of the triangular sides, and are fixed to the sheet 96. The support posts 42, 43, 44, and 45 may be glued to the sheet, or they may be fixed with a device so that they can be attached and detached. The zipper 46 has a slider 61, and the bottom stop is located near the vertex 112 of the triangular sides 49, 50, 51, and 52. It is preferable that the slider be of a type that can be operated from both the front and back (the same applies to the zippers below). One element tape of the zipper 46 extends along the edge of the triangular side 49, and the top stop is located near the vertex 111. The other element tape of the zipper 46 extends along the edge of the triangular side 52, and the top stop is located near the vertex 113. The zipper 83 has a slider 74, and the bottom stop is located near the vertex 118. One element tape of the zipper 83 extends along the edge of the triangular side 49, and the top stop is located near the vertex 111. The other element tape of the zipper 83 extends along the edge of the bottom surface 48, and the top stop is located near the vertex 117. The zipper 84 has a slider 75 and a bottom stop located near vertex 115. One element tape of the zipper 84 extends along the edge of the base 48, passes through vertex 116, and has a top stop located near vertex 117. The other element tape of the zipper 84 extends along the edges of the triangular sides 51 and 52, passes through vertex 114, and has a top stop located near vertex 113.

[0030] Similar to the second embodiment, when assembling the tent, the user folds the sheet 96 along the connected and fixed edges of the triangular sides and bottom, and closes the zippers 46, 83, and 84 to assemble the tent into a square pyramidal shape. When disassembling, the tent is disassembled by opening each zipper. Similar to the second embodiment, the disassembled tent is stored in a small volume in the form of a thin cone, section, or rod by bundling the support poles together and rolling it up or folding it.

[0031] [Fifth Embodiment] The tent that forms a square pyramidal shape when assembled, as shown in the second embodiment, can also be realized with a sheet of the shape shown in Figure 22. Figure 22 is a plan view of the tent 92 according to the fifth embodiment. As shown in Figure 22, the tent 92 of the fifth embodiment has a sheet 97, four support poles 42, 43, 44, and 45 that stretch it into a predetermined shape, and fasteners 46, 85, and 86 that join opposite sides. This embodiment corresponds to the case where N in the N-sided polygon of the present invention is 4, and corresponds to a hollow square pyramidal tent formed by a square base and four triangular sides. The sheet 97 has a square base 48 and four triangular sides 49, 50, 51, and 52 that are connected and fixed, and when assembled it takes on the shape of a hollow square pyramidal shape. The support poles 42, 43, 44, and 45 are arranged radially around the vertex 122, at the edges of the triangular sides, and are fixed to the sheet 97. The support posts 42, 43, 44, and 45 may be glued to the sheet, or they may be fixed with a device so that they can be attached and detached. The fastener 46 has a slider 61, and the bottom stop is located near the vertex 122 of the triangular sides 49, 50, 51, and 52. It is preferable that the slider be of a type that can be operated from both the front and back (the same applies to the fasteners below). One element tape of the fastener 46 extends along the edge of the triangular side 49, and the top stop is located near the vertex 121. The other element tape of the fastener 46 extends along the edge of the triangular side 52, and the top stop is located near the vertex 123. The fastener 85 has a slider 76, and the bottom stop is located near the vertex 127.

Claims

[Claim 1] A hollow N-sided pyramidal tent formed by an N-sided base (where N is an integer of 3 or more) and N triangular sides, One of the N sides forming the base is connected and fixed to one side of one of the N triangles, and the other (N-1) sides forming the base are fitted with openable and closable fasteners. When the tent is not assembled and the fasteners are not closed, the other (N-1) sides forming the bottom surface are not connected or fixed anywhere except to which the fasteners are attached. Of the N triangles, the adjacent triangles of the 1st to the Nth triangles are connected and fixed to each other by their adjacent sides, and the sides to which the Nth triangle and the 1st triangle are connected and fixed when the tent is assembled, and the sides to which the other (N-1) sides forming the base of the triangles other than the triangle connected and fixed to one of the N sides forming the base are connected and fixed to each other by the fasteners, and are not connected and fixed anywhere else. Overall, the base and the N triangles are connected and fixed to form a single sheet on a flat surface. With the vertex of the aforementioned hollow N-pyramid-shaped tent at the center, one column is attached to each of the N sides of the triangular lateral surface, radiating outwards. The tent is characterized in that, when assembling the tent, the other (N-1) sides forming the base and the sides of the triangle connected to those (N-1) sides are closed and connected with the fasteners, and the sides of the Nth triangle and the 1st triangle that are adjacent to each other are closed and connected with fasteners to form the hollow N-pyramid-shaped tent.
