Description

  The present invention relates to an extendable tent that is configured to be extendable and usable as a warehouse or the like.

  A bellows type warehouse tent structure is known as a telescopic tent structure according to a conventional example. The structure includes a plurality of roof frames movably provided in the front-rear direction, a seat covered by the roof frames, and a pantograph mechanism provided between the roof frames to connect the roof frames in an extendable manner. It consists of.

JP-A-9-209614 Japanese Utility Model Publication No. 54-6255

  The telescopic tent according to the conventional example has a limit in size, and there are only about 6 mx 6 m to 8 mx 8 m. For this reason, telescopic tents have not been used as large warehouses or hangars. Accordingly, an object of the present invention is to provide a telescopic tent that can be used as a large warehouse or the like.

  The configuration of the present invention that achieves the above object is as follows.

  (1) The invention according to claim 1 is configured such that a pantograph mechanism is interposed between a plurality of support columns each having a wheel at a lower end, and the side wall is configured by using a side wall frame structure that is extendable in the front-rear direction. A roof frame structure is interposed between the struts facing each other in the left-right direction, and a divided side wall sheet is attached to each of the struts adjacent to each other in the front-rear direction. It was constructed by sticking a roof sheet.

  (2) The invention according to claim 2 is the telescopic tent according to claim 1, wherein the support, the pantograph mechanism, and the frame structure for the roof are made of an aluminum alloy.

  In the present invention, if the number of support columns constituting the side wall is increased, the length in the front-rear direction can be made arbitrarily long. And since the sheet attached to the side wall is divided for each adjacent support column, and the sheet attached to the roof is also used for the adjacent roof frame structure, the sheet is used. The number can be easily increased, that is, a sheet having a length corresponding to a long frame can be easily attached.

  Thus, according to the present invention, it is possible to easily provide a long telescopic tent that can be used as a large warehouse or the like.

  In the invention according to claim 2, most of the framework structure of the telescopic tent according to the present invention is made of an aluminum alloy. With such a configuration, the weight is reduced, the expansion and contraction work is facilitated, and the labor required for transportation is reduced.

  In addition, the frame structure is connected both in the cross-sectional direction and in the front-rear direction, so that it is easy to assemble, disassemble, and pack, and it is possible to complete assembly, disassembly, and packing in a short time without requiring special skills.

  Hereinafter, an embodiment of a preferred invention will be outlined with reference to the drawings.

  FIG. 1 shows the framework structure of the telescopic tent 1 according to the present invention from the front side, and FIG. 3 shows the framework structure from the plane side. A roof frame structure 3 is interposed between the support columns 4 provided in pairs in the left-right direction (the arrow direction in the figure).

  FIG. 4 is a front view of the roof frame structure 3. The roof frame structure 3 is configured by interposing a plurality of vertical rods 3c between horizontal rods 3a and inclined rods 3b. FIG. 4 shows a roof structure when the roof shape is a single flow. When the roof shape is a double flow, as shown in FIG. What is necessary is just to join.

  FIG. 6A is a front view of the roof sheet 6, and FIG. 6B shows a state where the roof sheet 6 is attached to the roof of the telescopic tent 1. The roof sheet 6 has the same area as the area enclosed by the adjacent roof structure 6 and the side wall structure 2 between the adjacent roof structures 6 when the telescopic tent 1 is extended. It is a shape and covers the roof of the telescopic tent 1 by sticking between adjacent roof structures 6. As a material for the roof sheet, a curtain used in a normal tent can be used, and specifically, tarpaulin, ester canvas, polyester, or the like can be used. The attaching method is not particularly limited, such as attaching with a screw or attaching with a string.

  FIG. 2 shows the framework structure of the telescopic tent 1 according to the present invention from the side surface side. A pantograph mechanism 5 is interposed between the plurality of support columns 4 and is extendable in the front-rear direction (the arrow direction in the figure).

  FIG. 7 is a partial perspective view of the side wall structure. The support column 4 has two eaves members 4a and 4a erected on a support plate 4b, and a wheel 8 is attached to the lower part thereof.

  A pantograph mechanism 5 is interposed between the columns 4 and 4. The pantograph mechanism 5 is a combination of a large number of skewers 5a in an X-shape, and the skewers 5a are pivotally supported by a pivot 5b at the intersection. The support 4 and the pantograph mechanism 5 are attached by fixing the pivot 5b and the support 4 at the upper end or the lower end, and the pivot 5b and the support 4 at the end opposite to the fixed side have a groove provided in the support 5b. Is provided to be slidable in the vertical direction. With such a structure, the pantograph mechanism 5 can be expanded and contracted.

  FIG. 8 is a perspective view of the side wall sheet 7. The side wall sheet 7 is a rectangular body having a width of about the width between the adjacent struts 4 when the telescopic tent 1 is extended, and is stretched between the adjacent struts 4 to cover the side wall of the telescopic tent 1. Is. As the material for the side wall sheet, a curtain used in a normal tent can be used, and specifically, tarpaulin, ester canvas, polyester, or the like can be used.

  In invention of Claim 2, the support | pillar 4, the pantograph mechanism 5, and the frame structure 3 for roofs were made from the aluminum alloy. As a result, the durability is remarkably improved, and the weight can be reduced and the conveyance can be extremely easy. Further, if all screws and bolts are used without using welding or rivets, the durability can be further improved.
