Description

[Technical field]

[0001] The present invention relates to a tent and its membrane body that are temporarily installed as a temporary warehouse, a product storage facility, a material storage area, etc. [Background technology]

[0002] Conventionally, an example of this type of tent is a tent structure made of multiple gate-shaped frames with a ceiling and pillars connected so that they can expand and contract in the front-to-rear direction, covered with a membrane body to make it expandable and contractable like an accordion (Patent Document 1).

[0003] 9, the above-mentioned conventional tent has a membrane body 3 covering a gate-shaped frame 5 constituting the gable side of the tent structure, a curtain rail 10 attached to the gate-shaped frame 5 on the gable side, an entrance opening is provided in the membrane body 3 on the gable side, and the entrance opening is opened and closed by curtain membranes 3a, 3b hung from the curtain rail 10. A known tent to be installed outdoors has the opening and closing edges of the curtain membranes 3a, 3b fixed to side poles 11a, 11b hung from the curtain rail 10, and the closed position is maintained by the magnetic force of magnets attached to the side poles 11a, 11b to prevent the curtain membranes 3a, 3b from being blown up by the wind and letting in rain and the like from outside when the curtain membranes 3a, 3b are closed.

[0004] [Patent Document 1] JP 2023-97571 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the above-mentioned conventional tents, the curtain membrane is opened when materials are brought in and out of the warehouse, but the gable opposite the open curtain membrane generally does not have a curtain membrane, or if there is a curtain membrane, it is closed to prevent rain, etc. from getting in. Therefore, if a strong wind blows into the tent while the curtain membrane, which is the entrance / exit on one gable, is open, the other gable is pushed by the strong wind, causing the entire tent to tilt, and there is also a risk of the tent collapsing if an unexpected strong wind blows.

[0006] SUMMARY OF THE PRESENT EMBODIMENTS The main object of the present invention is to provide a tent and its membrane body that can adequately allow wind blowing into the tent to escape while preventing rain from entering. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, one aspect of the present invention comprises a membrane body that is placed over a tent structure, the membrane body comprising a mesh window stretched over an end surface of the membrane body, a cover sheet whose upper edge is fixed to the membrane body above the mesh window and which covers the mesh window in an openable and closable manner, and a first connecting portion that partially connects the cover sheet to the membrane body near the side edge of the mesh window.

[0008] A second connector may be provided partially connecting the bottom edge of the cover sheet to the membrane adjacent the bottom edge of the mesh window.

[0009] The membrane body has an entrance / exit opening on the end surface and is provided with a curtain membrane that opens and closes the entrance / exit opening, and the mesh window and the cover sheet can be provided on the curtain membrane.

[0010] The first connecting portion may be a string connecting the cover sheet and the membrane body.

[0011] The first connecting portion may include strings provided on both side edges of the cover sheet, and loops attached to the membrane body through which the strings pass.

[0012] The second connecting portion may be a string connecting the cover sheet and the membrane body.

[0013] The second connecting portion may include strings provided on both side edges of the cover sheet, and loops attached to the membrane body through which the strings pass.

[0014] The cover sheet may further include a string member for tying and holding the cover sheet in a rolled up state above the mesh window.

[0015] In the tent according to the present invention, the membrane body is placed over the tent structure. Effect of the Invention

[0016] According to the present invention, when it is not raining, if the cover sheet is open, the wind can pass through the mesh window, and when it is raining, if the cover sheet is closed, the rain will not enter the tent and the wind can pass through the part between the mesh window and the cover sheet that is not connected by the connecting part, so that even if a strong wind blows into the tent, it is possible to prevent the rain from entering while allowing the strong wind that has entered the tent to escape, thereby preventing the tent from tilting or collapsing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] An embodiment of a tent according to the present invention will be described below with reference to Fig. 1 to Fig. 8. Fig. 1 is a back view (rear side) of the tent, Fig. 2 is a front view (front side) of the tent, Fig. 3 is a side view of the tent, Fig. 4 is a side view of the tent when deflated, Figs. 5 to 7 are partially enlarged front views of the tent, and Fig. 8 is a partially enlarged perspective view of the tent. Note that the same reference numerals are used throughout the drawings to designate the same or similar components.

[0019] 1 to 4, tent 1 has a tent structure 2 covered with a membrane body 3. The tent structure 2 in the illustrated example is of a prefabricated type, and includes a plurality of portal frames 5 connected by an X-link mechanism 4 (FIG. 3) so as to be extendable and contractible in the front-rear direction. Casters 5a are attached to the lower part of the portal frames 5.

[0020] The membrane body 3 is composed of a ceiling surface, front and rear end surfaces, and left and right flat side surfaces. The material of the membrane body 3 may be synthetic fiber such as polyester. A mesh window 6 is installed on the end surface of the membrane body 3.

[0021] 5 to 8, the mesh window 6 is covered by a cover sheet 7 in an openable and closable manner. An upper edge 7a (FIG. 6) of the cover sheet 7 is liquid-tightly adhered and fixed to the film 3 above the mesh window 6 by heat sealing or the like. The side and bottom edges of the cover sheet 7 are not fixed to the film 3 around the mesh window 6, so that the mesh window 6 can be opened and closed by the cover sheet 7.

[0022] A plurality of first connecting portions 8 are provided to partially connect both side edges of the cover sheet 7 and the membrane body 3 near both side edges of the mesh window 6. The first connecting portions 8 are provided intermittently along the side edges of the mesh window 6 at a predetermined interval d (FIG. 7).

[0023] A second connecting portion 9 is also provided, which partially connects the bottom edge of the cover sheet 7 and the membrane body 3 near the bottom edge of the mesh window 6. In the illustrated example, the second connecting portion 9 is provided in only one place on one cover sheet 7, but if the horizontal dimension of the cover sheet 7 is wider than in the illustrated example, multiple second connecting portions 9 can be provided at intervals. The second connecting portion 9 can also be omitted. The mesh window 6 and cover sheet 7 are vertically long rectangular (quadrilateral) in the illustrated example, but they can also be square.

[0024] In the illustrated example, as shown in Fig. 1, the membrane body 3 has an entrance opening on the end surface, and is equipped with curtain membranes 3a, 3b that open and close the entrance opening, and the curtain membranes 3a, 3b are provided with a mesh window 6 and a cover sheet 7. If there is no curtain membrane on the end surface, the mesh window 6 and cover sheet 7 are provided in the membrane body that constitutes the end surface.

[0025] The curtain membranes 3a, 3b in the illustrated example are provided on the tent structure 2, hung from a curtain rail 10 (Fig. 1), and open to the left and right, so that they can be opened in the direction of the arrow X from the closed state in Fig. 1. The opening and closing edges of the left and right curtain membranes 3a, 3b are fixed to side poles 11a, 11b, respectively, which are hung movably on the curtain rail 10. A magnetic plate (not shown) is embedded in one side of the side poles 11a, 11b, so that when the left and right curtain membranes 3a, 3b are closed, they are attracted to each other by magnetic force, thereby maintaining the closed state of the curtain membranes 3a, 3b.

[0026] The mesh window 6 is constructed by stretching a synthetic fiber mesh sheet around the window opening provided in the membrane body 3 on the gable surface, in the illustrated example, the curtain membranes 3a and 3b, by heat sealing, etc. The size of the mesh of the mesh window 6 may be any size that allows wind to pass through.

[0027] By tensioning the mesh window 6 on the membrane 3, the membrane 3 on the end face on which the mesh window 6 is provided can maintain a constant tension. In other words, if the mesh window 6 is not tensioned, the membrane on the end face will lose its shape retention at the window opening and become loose, but by tensioning the mesh window, the membrane on the end face can maintain its shape in a tensioned state.

[0028] The cover sheet 7 covers the mesh window 6 with its upper edge 7a fixed to the membrane body 3 on the end face, thereby preventing rainwater from entering from the top of the cover sheet 7, and the side edges are partially connected to the membrane body 3 on the end face by first connecting parts 8, preventing rain from entering the tent through the mesh window 6. The cover sheet 7 can cover the mesh window 6 by making it larger than the dimensions of the mesh window 6.

[0029] In the illustrated example, the first connecting portion 8 and the second connecting portion 9 comprise strings 12 attached to both side edges and bottom edges of the curtain membranes 3a, 3b, and rings 13 attached to the membrane body 3 through which the strings 12 pass.

[0030] In the illustrated example, the ring 13 through which the string 12 passes is formed by attaching a ring-shaped rivet to a triangular piece of cloth sewn to the membrane body 3 near the side edge of the mesh window 6. The ring 13 through which the string 12 passes is not limited to the illustrated example, and may be a ring-shaped string sewn to the membrane body 3. Also, although not shown, a string may be attached to the membrane body 3 and a ring through which the string passes may be provided on the cover sheet 7. Furthermore, the first connecting part 8 and the second connecting part 9 are not limited to a combination of a string and a ring, and may be configured to connect the string attached to the membrane body 3 and the string attached to the cover sheet 7 by tying them together. The strings constituting the first connecting part 8 and the second connecting part 9 may be rubber strings. Furthermore, the first connecting part 8 and the second connecting part 9 are not limited to a mode in which the string is passed through a ring and tied, and may be configured to hang a locking member such as a carabiner on the membrane body 3 and lock it into a hole (ring) provided in the cover sheet 7, or may be configured to be connected by a hook-and-loop fastener.

[0031] The distance d between the top and bottom of the first connecting portion 8 depends on the height of the mesh window 6, but in the illustrated example, it is 40 cm. If this distance d is too narrow, when the membrane body 3 and the cover sheet 7 are connected by the first connecting portion 8, it may be difficult for wind to pass through the gap between the cover sheet 7 and the membrane body 3, so it is preferable to provide the distance d of, for example, 20 cm or more.

[0032] When the cover sheet 7 is opened, as shown in Fig. 6, the cover sheet 7 can be held in a rolled up state by tying it over the top of the mesh window 6 using a string member 14. The string member 14 can be attached to the membrane body 3 or to the top of the cover sheet 7. When it is not raining, etc., keeping the cover sheet 7 rolled up allows wind to pass through the mesh window 6 more easily.

[0033] In the tent 1 having the above configuration, when it is not raining, the mesh window 6 can be left open, for example by rolling up the cover sheet 7, so that wind blowing into the tent from the entrance and exit of the tent can pass through the mesh window 6. When it is raining, the cover sheet 7 and the membrane body 3 are connected with the first connecting part 8 (and the second connecting part 9), so that the cover sheet 7 is not blown up by the wind blowing into the tent and a gap is formed between the cover sheet 7 and the membrane body 3. This prevents rainwater from entering the tent, and allows the wind blowing into the tent to pass through the mesh window 6 and escape through the gap between the cover sheet 7 and the membrane body 3.

[0034] By configuring it as described above, it is possible to prevent rainwater from entering through the gable side even on rainy days while allowing wind to pass through inside the tent, thereby preventing the tent from tilting or collapsing even in strong winds during rainy weather.

[0035] The present invention should not be construed as being limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
