Description

Technical Field

[0001] The present invention relates to a seat fixing structure and a seat fixing method for a tent.

Background Art

[0002] At a construction site, it is often the case that a pipe tent is assembled in a construction yard or the like, and materials and equipment are stored inside the tent. Since a pipe tent can be assembled and disassembled relatively easily, it can be assembled quickly, and when the installation location needs to be moved, it can also be quickly disassembled and assembled at a new location. Furthermore, by assembling the framework to a desired size and surrounding the framework with a sheet, tents of various sizes can be formed, so a tent of a size corresponding to the scale and number of materials and equipment to be stored can be installed in a construction yard or the like.

[0003] For example, an opening for entry and exit is provided in the gable part of the tent, and by spreading a part of the sheet to open the opening, materials and equipment can be carried in and out. After the materials and equipment are carried in, the opening is closed with a part of the sheet. Here, Patent Document 1 proposes an attachment device for a tent cloth that is applied when attaching the tent cloth to the frame members constituting the tent.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Here, referring to FIGS. 1 to 3, an example of a conventional tent will be described. FIG. 1 is a perspective view of an example of a conventional pipe tent, showing a state in which the opening of the sheet in the gable part is closed. On the other hand, FIG. 2 is a view showing a state in which the opening of the pipe tent is open, and FIG. 3 is an enlarged view of part III of FIG. 1.

[0006] The illustrated pipe tent 30 has a frame 10 formed by assembling multiple steel pipes in the beam direction and girder direction, and a sheet 20 (tent fabric) that surrounds the frame 10. As clearly shown in Figure 2, at the end 31, the sheet 20 has an indoor sheet 21 that is gate-shaped when viewed from the front and has an entrance / exit opening 23 in the center, and an outdoor sheet 22 that is located outside the indoor sheet 21 and partially overlaps with the indoor sheet 21. Although not shown in the illustration, a similar opening and closing configuration may be provided at the far end of the drawing.

[0007] As shown in Figure 2, multiple loop-shaped ropes 25 are attached to the indoor sheet 21 located on the left and right sides, with some overlapping in the vertical direction. On the other hand, eyelet fittings 26 into which each loop-shaped rope 25 is loosely fitted are attached to the outdoor sheet 22 at positions corresponding to each rope 25.

[0008] When closing the opening 23 shown in Figure 1 with the outdoor sheet 22, as shown in Figure 3, the lower end of the upper rope 25A is aligned with the eyelet fitting 26B located below, the rope 25B at the position corresponding to the eyelet fitting 26B is pulled outwards from the eyelet fitting 26B in the X1 direction, and the rope 25B is then pulled downwards so as to hook onto the loop-shaped rope 25A, so that the ropes 25A and 25B are crossed while under tension. This is then done sequentially with the lower ropes 25C and 25D.

[0009] As shown in Figure 1, by fixing the rope 25 at the lowest end to the fixing part 26a at the lowest end, a sheet fixing structure 40 is formed in which the opening 23 is closed by the outdoor side sheet 22.

[0010] According to the illustrated sheet fixing structure 40, the opening 23 of the tent 30 can be reliably closed by the outdoor sheet 22, protecting the equipment and materials housed in the tent 30 from wind and rain. Furthermore, ventilation is ensured through a small gap between the indoor sheet 21 and the outdoor sheet 22, thereby suppressing rusting of the equipment and materials caused by moisture that may accumulate inside the tent 30.

[0011] However, this method of securing the sheet requires repeatedly performing the extremely tedious task of threading the rope 25 through the eyelet fitting 26 from top to bottom, crossing the upper and lower ropes 25 together, and pulling them downwards. This makes closing the opening 23 time-consuming and laborious. Similarly, opening the opening 23 requires the reverse process, starting from below and uncrossing the ropes 25 together, thus also making opening the opening 23 time-consuming and laborious.

[0012] Furthermore, because the upper and lower ropes 25 are crossed while being pulled taut, it is necessary to ensure that the distance between the upper and lower ropes (or the distance between the eyelets) is always a constant length t, as shown in Figure 1.

[0013] Furthermore, because the tensile force from the lower rope 25 is concentrated at the lower central point of the loop-shaped rope 25, this lower central point of the loop-shaped rope 25 is prone to breaking, often resulting in frequent maintenance (replacement).

[0014] As described above, the sheet fixing structure 40 and sheet fixing method in the illustrated example tent 30 have various inherent problems. Therefore, other forms of sheet fixing methods and fixing structures can be considered, such as structures and methods that fix the indoor sheet and the outdoor sheet with zippers or Velcro (registered trademark).

[0015] First, regarding the structure in which the indoor and outdoor sheets are secured by zippers, in tents with a relatively large surface area that are susceptible to wind pressure, there is a problem in that when attempting to open or close the zippers while the indoor and outdoor sheets are under wind pressure, it is extremely difficult to do so because both are under tension due to the wind pressure.

[0016] Next, regarding the structure in which the indoor and outdoor sheets are fixed together with Velcro, there is a problem in that dirt and dust easily adhere to Velcro, and dust and other debris are especially likely to be generated at construction sites, which can reduce the fixing strength due to the accumulation of dirt and other debris. Therefore, sheet fixing structures using fasteners or Velcro are also undesirable.

[0017] This invention has been made in view of the above problems, and aims to provide a sheet fixing structure and sheet fixing method for a pipe tent used to house materials and equipment in construction yards, etc., which can firmly fix an indoor sheet with an opening and an outdoor sheet that closes the opening, and which does not require much effort or time to fix the sheets together. [Means for solving the problem]

[0018] To achieve the above objective, one embodiment of the tent sheet fixing structure according to the present invention is: In a tent made of pipes, the sheet surrounding the frame comprises an indoor sheet with an opening for entry and exit, and an outdoor sheet that closes the opening and partially overlaps the indoor sheet, and the outdoor sheet is detachably fixed to the indoor sheet, in a tent sheet fixing structure, The indoor sheet is provided with a plurality of first holes spaced apart in the vertical direction, and the outdoor sheet is provided with a plurality of second holes at positions corresponding to the first holes. The fastener comprises a locking piece and a protruding piece, the protruding piece being inserted from the indoor side into the first and second holes which are aligned with each other and protruding outwards, and the locking piece being locked to the indoor side of the first hole. The rope hanging down from above the outdoor sheet is, while under tension, sequentially wrapped around a plurality of overhanging pieces extending outwards, thereby fixing the outdoor sheet to the indoor sheet and closing the opening.

[0019] According to this aspect, with respect to a plurality of first holes in the indoor-side sheet and a plurality of second holes in the outdoor-side sheet that are aligned with each other, the protruding pieces of the fastener are inserted from the indoor side, and in a state where the locking pieces of the fastener are locked to the indoor side of the first holes, a rope hanging from above the outdoor-side sheet is sequentially wound around each protruding piece in a pulled state, and the indoor-side sheet and the outdoor-side sheet are fixed, so that both sheets can be firmly fixed, and the labor and time required for fixing the sheets to each other can be reduced.

[0020] Also, in this fixing structure, the labor and time can be reduced even when releasing the fixation. And all the problems in the conventional sheet fixing structure 40 and sheet fixing method described using FIGS. 1 to 3 can be solved.

[0021] Also, in another aspect of the sheet fixing structure according to the present invention, At the base of the protruding piece on the side of the locking piece, an engaging portion that can be removably engaged with a nut is provided. The protruding piece is inserted into the first hole, and the nut is inserted into the protruding piece and engaged with the engaging portion.

[0022] According to this aspect, an engaging portion is provided at the base of the protruding piece on the side of the locking piece, and the nut is inserted into the protruding piece protruding from the first hole and engaged with the engaging portion, so that the fastener can be smoothly and firmly attached to the first hole of the indoor-side sheet.

[0023] Also, in another aspect of the sheet fixing structure according to the present invention, The protruding piece is provided with a plurality of convex portions at intervals in its longitudinal direction.

[0024] According to this aspect, since the protruding piece has a plurality of convex portions spaced apart in its longitudinal direction, the pulling force when winding the rope around the protruding piece while pulling the rope can be entrusted to the convex portions, and further, the winding posture in the pulled state can be maintained. Also, since there are two or more convex portions, the convex portion on the tip side of the protruding piece is made to protrude from the second hole, and the operator pushes the outdoor sheet toward the indoor sheet side by hand to make the second and subsequent convex portions protrude, and the rope can be hooked on the convex portion on the root side and wound. Therefore, for example, even in a strong wind environment, it is possible to smoothly and surely fix the outdoor sheet to the indoor sheet.

[0025] Also, another aspect of the sheet fixing structure according to the present invention is characterized in that the fastener is a cut product of a steel plate.

[0026] According to this aspect, since the fastener is a cut product of a steel plate, the labor for manufacturing the fastener having a protruding piece and a locking piece provided with a plurality of convex portions can be suppressed, and the fastener can be manufactured at as low a cost as possible.

[0027] Also, in another aspect of the sheet fixing structure according to the present invention, characterized in that both the first hole and the second hole are provided with eyelets.

[0028] According to this aspect, since eyelets are attached to both the first hole and the second hole, the periphery of the first hole and the second hole of the sheet is reinforced, preventing tearing or the like from occurring from a part of the hole, and the durability of the sheet can be increased. At the same time, the protruding piece of the fastener can be smoothly inserted into the mutually aligned first hole and second hole.

[0029] Also, one aspect of the tent sheet fixing method according to the present invention is A method for securing tent sheets in a pipe-framed tent, wherein the sheet surrounding the frame comprises an indoor sheet with an opening for entry and exit, and an outdoor sheet that closes the opening and partially overlaps the indoor sheet, and the outdoor sheet is detachably fixed to the indoor sheet, The indoor sheet is provided with a plurality of first holes spaced apart in the vertical direction, and the outdoor sheet is provided with a plurality of second holes at positions corresponding to the first holes. The fastener, which comprises a locking piece and a protruding piece, has the protruding piece inserted from the indoor side through the first and second holes which are aligned with each other, and protrudes outwards to the outdoor side, with the locking piece locked to the indoor side of the first hole at this time. The method is characterized by sequentially winding a rope hanging from above the outdoor sheet onto a plurality of overhanging pieces extending outwards to the outdoors, thereby fixing the outdoor sheet to the indoor sheet and closing the opening with the outdoor sheet.

[0030] According to this embodiment, the protruding pieces of the fasteners are inserted from the indoor side into multiple first holes in the indoor side sheet and multiple second holes in the outdoor side sheet, which are aligned with each other. With the locking pieces of the fasteners locked to the indoor side of the first holes, the rope hanging from above the outdoor side sheet is pulled taut and sequentially wrapped around each protruding piece to fix the indoor side sheet and the outdoor side sheet together. This allows both sheets to be firmly fixed together and reduces the time and effort required to fix the sheets together. Furthermore, the time and effort required to release the sheets from being fixed together can also be reduced. To release the sheets from being fixed together, the rope is unwound sequentially from the lower fasteners, the nuts of each fastener are removed, and the fasteners are pulled into the tent to remove them. [Effects of the Invention]

[0031] As can be understood from the above explanation, the tent sheet fixing structure and sheet fixing method of the present invention can provide a sheet fixing structure and sheet fixing method that can firmly fix an indoor sheet with an opening and an outdoor sheet that closes the opening to a pipe tent that houses materials and equipment in a construction yard, and that does not require much effort or time to fix the sheets together. [Brief explanation of the drawing]

[0032] [Figure 1] This is a perspective view of an example of a conventional pipe-frame tent, showing the end section with the sheet opening closed. [Figure 2] This diagram shows a conventional pipe-frame tent with its openings in the open position. [Figure 3] This is an enlarged view of part III in Figure 1. [Figure 4] This is a perspective view of an example of a fastener used in the sheet fixing method according to the embodiment. [Figure 5] This is a process diagram illustrating the sheet fixing method according to the embodiment. [Figure 6] Following Figure 5, this is a process diagram illustrating the sheet fixing method according to the embodiment. [Figure 7] Following Figure 6, this is a process diagram illustrating the sheet fixing method according to the embodiment. [Figure 8] Following Figure 7, this is a process diagram illustrating the sheet fixing method according to the embodiment. [Figure 9] Following Figure 8, the next diagram is a process diagram illustrating the sheet fixing method according to the embodiment. [Figure 10] Following Figure 9, this is a process diagram illustrating the sheet fixing method according to the embodiment, and is a perspective view of an example of the sheet fixing structure according to the embodiment. [Modes for carrying out the invention]

[0033] The tent sheet fixing structure and sheet fixing method according to the embodiment will be described below with reference to the attached drawings. In this specification and drawings, substantially identical components may be denoted by the same reference numerals to avoid redundant explanations.

[0034] [Tent sheet fixing structure and sheet fixing method according to an embodiment] An example of a tent sheet fixing structure and sheet fixing method according to the embodiment will be described with reference to Figures 4 to 10. Here, Figure 4 is a perspective view of an example of a fastener used in the sheet fixing method according to the embodiment. Figures 5 to 10 are sequential process diagrams illustrating the sheet fixing method according to the embodiment, and Figure 10 is a perspective view of an example of a sheet fixing structure according to the embodiment.

[0035] As shown in Figure 4, the fastener 50 applied to the method of securing the tent sheet comprises a locking piece 54 and an overhanging piece 51. The overhanging piece 51 has multiple (three in the illustrated example) protrusions 52 on its upper and lower sides in the longitudinal direction, and an interlocking portion 53 is provided at the base of the overhanging piece 51 on the side with the locking piece.

[0036] The nut 56 and washer 57 are welded together with their respective screw holes 56a and 57a aligned, and after being inserted into the protruding piece 51, the screw hole 56a of the nut 56 engages with the engagement portion 53.

[0037] The fastener 50 is a cut-and-processed (laser-cut) product of a steel plate such as SUS. Therefore, although it is a component with a relatively complex shape, as shown in the illustrated example, having a protruding piece 51 with multiple protrusions 52 and interlocking parts 53, and a locking piece 54, its manufacturing effort can be reduced, and it can be manufactured as inexpensively as possible.

[0038] The following describes a method for fixing a sheet using the fastener 50 and a sheet fixing structure formed by this method.

[0039] As shown in Figure 5, the pipe tent 70 has a frame 10 formed by assembling multiple steel pipes in the beam direction and the girder direction, and a sheet 60 that surrounds the frame 10. At the end 71 of the tent 70, the sheet 60 has an indoor sheet 61 which is gate-shaped when viewed from the front and has an entrance / exit opening 61a in the center, and an outdoor sheet 62 which is located outside the indoor sheet 61 and partially overlaps with the indoor sheet 61.

[0040] Multiple (six in the illustrated example) second holes 64 are provided vertically spaced apart on the left and right sides of the outdoor sheet 62, and eyelet fittings are attached to each second hole 64. Although not visible in Figure 5, first holes 63 (see Figure 6) are provided on the indoor sheet 61 at positions corresponding to each second hole 64, and eyelet fittings are also attached to each first hole 63.

[0041] As described below, the protruding piece 51 of the fastener 50 is inserted sequentially into the first hole 63 and the second hole 64, which are aligned with each other. However, because eyelets are attached to both holes, the rounded surface of the eyelets guides the tip of the protruding piece 51 into the inside of the eyelet, allowing for smooth insertion of the protruding piece 51. Furthermore, the eyelets reinforce the area around the first hole 63 of the indoor sheet 61 and the area around the second hole 64 of the outdoor sheet 62, improving the durability of each sheet.

[0042] Near the left and right second holes 64 of the outdoor sheet 62, ropes 65 hang down, their upper ends fastened to the outdoor sheet 62 by fasteners 65a.

[0043] The state shown in Figure 5 is when the indoor sheet 61 and the outdoor sheet 62 are released from their fastening, for example, when storing equipment inside the tent 70 or, conversely, when removing equipment from the tent 70. By opening a part of the outdoor sheet 62 at the gable end 71 of the tent 70, the opening 61a in the center of the indoor sheet 61 is opened. Here, a similar entrance / exit opening and an outdoor sheet to close the opening may also be provided at the opposite gable end of the tent 70 (not shown).

[0044] As shown in Figure 6, the protruding piece 51 of the fastener 50 is inserted through the first hole 63 of the indoor sheet 61 from the indoor side of the tent 70 and extended outwards in the X2 direction, with the locking piece 54 being locked to the indoor side of the first hole 63.

[0045] Next, as shown in Figure 7, the nut 56 with the washer 57 attached is inserted in the X3 direction from the tip side of the protruding piece 51, and the nut 56 is engaged with the interlocking portion 53 at the base of the protruding piece 51, thereby attaching (fixing) the fastener 50 to the indoor sheet 61.

[0046] Next, as shown in Figure 8, the second hole 64 of the outdoor sheet 62 is inserted into the protruding piece 51, causing the protruding piece 51 to extend outwards from the outdoor sheet 62 in the X4 direction. During this extension, the protrusion 52A at the tip of the protruding piece 51 is extended through the second hole 64, and then the worker manually pushes the outdoor sheet 62 toward the indoor sheet side with pressure P to extend the second and subsequent protrusions 52B and 52C.

[0047] After the protruding portion 52C at the base of the overhanging piece 51 extends outward from the outdoor sheet 62, as shown in Figure 9, the worker applies pressure P to the outdoor sheet 62 and pulls the rope 65 hanging horizontally downward, transferring the tensile force Q to the protruding portion 52C while winding the rope around the overhanging piece 51 in the X5 direction. This method makes it possible to smoothly and securely fix the outdoor sheet 62 to the indoor sheet 61, even in strong wind conditions.

[0048] For example, after sequentially fixing the fasteners 50 to each of the first holes 63 shown in Figures 6 and 7, the sheet fixing structure 80 shown in Figure 10 is formed by winding the ropes 65 shown in Figures 8 and 9 while pulling them, starting from the upper fasteners 50.

[0049] The illustrated tent 70 is a pipe-frame tent used to house equipment and materials in a construction yard or similar area at a construction site. The sheet fixing structure 80 ensures ventilation between the inside and outside of the tent 70 while reliably closing the entrance / exit opening 61a.

[0050] According to the illustrated sheet fixing method, the indoor sheet 61 and the outdoor sheet 62 can be firmly fixed together, and the time and effort required to fix the sheets together can be reduced.

[0051] Furthermore, to release the fixing of the indoor sheet 61 and the outdoor sheet 62 to the state shown in Figure 5, the procedure is the reverse of the fixing method: the rope 65 is unwound starting from the lower fasteners 50, the nuts 56 of each fastener 50 are removed, and the fasteners 50 are pulled into the tent 70 to remove them. Therefore, the effort and time required to release the sheets from each other can be reduced.

[0052] Furthermore, other embodiments may be used in which other components are combined with the configurations listed in the above embodiments, and the present invention is not limited in any way to the configurations shown herein. In this regard, modifications can be made without departing from the spirit of the present invention, and can be appropriately determined according to the application form. [Explanation of Symbols]
