DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the openable tent according to the present invention will be described. The openable tent 1 according to the present invention, as shown in FIGS. A pair of rails 2 are arranged in parallel on both sides of a construction site or a place where goods are stored, and both ends of a plurality of support frames 3 are run over the rails 2 so as to run on the rails 2. The basic structure is such that the sheet 4 is unfolded by attaching the sheet 4 and increasing the interval between the supporting frames 3 adjacent to each other, and the sheet 4 can be folded by reducing the interval between the supporting frames 3.

The support frame 3 is made of a truss beam having a light weight and strength, and a traveling carriage 7 disposed on the rail 2 at both ends so as to be orthogonal to the length direction of the support frame 3. Is provided so that each support frame 3 can freely move on the rails 2 while being supported by the traveling carriage 7. When the span is large, the support frame 3 may be a box-shaped truss beam.

The support frames 3 are common in the configuration in which the traveling carriages 7 are provided at both ends.
Due to the difference in the role of expanding and folding the seat 4, both ends of the rail 2, that is, the drive support frames 3a disposed outside when the tent is viewed from a plane, It comprises a driven support frame 3b disposed between the frames 3a, and a drive motor 9 is provided in each of the drive support frames 3a.

As shown in FIG. 6, the width W is substantially the same as the width of the traveling carriage 7, and as shown in FIG. 7, the support frames 3 are brought close to each other to fold the seat 4. The upper surface of the half of the seat 4 connected between the support frames 3 is set to a size that prevents the upper surface from rainwater or the like.

As shown in FIG. 5, the traveling carriage 7 is attached to the lower end of the axle 23 of the wheel 22 attached to the traveling carriage 7 so as to face the lower surface of the upper flange of the rail 2.
There is provided a stopper 24 for preventing floating from coming off.

Further, as shown in FIG. 2, when the respective carriages 7 are brought closer to each other and the seat 4 is folded, the respective carriages 7 which are in contact with each other are integrally fixed. It is preferable to provide fixing means 25 such as bolts on the side surfaces facing each other.

In the openable / closable tent of the present invention configured as described above, as described above, each support frame 3 holding the seat 4 is movably arranged along the rails 2 on both sides, and A wire 5 stretched without looseness between both end supports 6 of each of the pulleys 10, 1 is attached to each support frame 3.
Since the seat 4 is hung by the wires 5 through the hanging members 13, the traveling carts 7 of the support frames 3 are brought close to each other as shown in FIG. When moved, the sheet 4 can be folded into many valleys, and as shown in FIG.
By moving the carriages 7 of the support frame 3 apart from each other, the seat 4 can be fully or partially unfolded.

Therefore, when used as a work place at a construction site, to avoid rain or direct sunlight, the traveling carts 7 of the support frame 3 are moved so as to be separated from each other, and the upper surface of the work place is covered with the seat 4. When it is better to open the upper surface as in the case of carrying in work, the traveling carriages 7 are moved so as to approach each other so that the seat 4 is folded. When it is desired to partially cover the vehicle 4, the deployed portion and the folded portion of the seat 4 may be freely selected as appropriate by pulling apart the traveling vehicle 7 and approaching the portion.

When the workplace is long, the number of driven support frames 3b arranged between the outer drive support frames 3a among the support frames 3 is increased to increase the overall length of the tent 1. Alternatively, a self-propelled motor may also be attached to the driven support frame 3b to reduce the traction load on the drive support frame 3a and to make the deployment of the seat 4 more efficient. In addition, if the locking device is appropriately provided on the wheels 22 of the traveling vehicle 7, the support frame 3 does not move due to the wind pressure applied to the seat 4.

Further, when the traveling carriages 7 are brought close to each other and the seat 4 is folded, if the traveling carriages 7 in contact with each other can be integrally fixed by the fixing means 25, the seat 4 is folded. In order to prevent inadvertent movement of the support frame 3 at the time, or to install and remove the tent 1, the wire 5 connected to the column 6 can be lifted and moved together by a crane or the like by removing the wire 5 connected to the column 6.

[0025]

As described above, in the opening / closing tent according to the present invention, the seat can be developed by increasing the distance between the adjacent support frames, and the wire stretched between both ends of the rail can be used in each case. Since the sheet is suspended by the wire by being interposed in the support frame, a large-area sheet can be folded into many valleys by reducing the interval between the support frames. There is an operational effect that any part can be freely opened and closed by appropriately selecting an operation.

Further, the wires for suspending the seat are connected between the columns at both ends of the rails in a tightly tensioned state, and each support frame is connected to these tensioned wires via pulleys. Since it is arranged movably along the rails, when the seat is folded and each support frame is moved to either the center part or one side, wires etc. are placed on the upper surface of the workplace after these support frames have moved. There is an advantage that a space without obstacles can be formed, and material can be carried in and construction work can be efficiently performed using this space.

Further, since the tents can be collectively moved by a crane or the like by fixing the adjacent support frames to each other, the installation and removal can be easily performed, and the tent can be assembled and installed at another place.

Moreover, since the seat cover is provided on the upper surface of each support frame, it is possible to appropriately prevent accumulation of rainwater and dust between the folded sheet valleys when the sheet is folded. It helps to prevent loosening and deterioration of the sheet.

In the above embodiment, the tent was described as a temporary tent for a construction site or a simple warehouse. However, if the tent is used as a sunshade for a water tank or a pool or as a dust tent, for example, water quality due to the propagation of algae can be obtained. In addition, when the tent is folded by moving the support frame, cleaning work can be performed efficiently because there is no obstacle on the top of the water tank when the tent is folded by moving the support frame. . In this case, by appropriately providing drain holes in the tent sheet, drainage of rainwater and discharge of water vapor generated in the tank can be appropriately performed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable tent which is suitably used as a temporary tent or a simple warehouse at a construction site or the like.

[0002]

2. Description of the Related Art An openable / closable tent used at a construction site of a building is, for example, a relatively large openable / closable tent as described in JP-A-9-296609 or Utility Model Registration No. 2558016. A tent has been proposed. These tents are temporary tents for work, such as construction sites, which enable work even in rainy weather.
The movable tent described in Japanese Patent No. 296609 has a structure in which a chin cap is provided at the center of the roof and both sides are inclined. A wire is stretched movably along the part, a sheet corresponding to a roof is attached to the wire via a support member, and the sheet is opened and closed by moving the wire.

On the other hand, a temporary roof described in Utility Model Registration No. 2558016 supports both ends of a steel pipe disposed between roof frames by rollers provided on opposed roof frames so as to be horizontally movable. A sheet is hung on a steel pipe, and an opposing roof frame is moved to expand and contract a temporary roof.

[0004]

The problem to be solved by the present invention is disclosed in Japanese Patent Application Laid-Open No. 9-296609.
The open / close movable tent described in the item has a tent cap fixed in the center, and the tent ground is supported by a rope stretched from the support member provided on this camp cap to the support members provided on the rails on both sides. There is a limit to the width of the seat, and in order to increase the width, it is necessary to take a method such as providing a beam member between the jinkasa and the rail portion in parallel, and also make the jinkasa and the beam material longer. For this purpose, reinforcement means such as fixing the support beam between the jinkasa and the rail section, or erecting a support pillar below the jinkasa and the beam material is necessary, and even if the tent is closed and the top surface is opened, Due to the presence of the beam, there was a problem that it was not possible to efficiently carry in materials from the upper surface and perform construction work.

[0005] Further, in this movable tent for opening and closing, after the pillars, the chin caps and the rails on both sides are fixed to the structure under construction, the seat is supported by the chin caps and the rails. However, there is a disadvantage that the operation becomes complicated.

On the other hand, the temporary roof described in Utility Model Registration No. 2558016 has a roof structure in which a part of a steel pipe is inserted into a roof frame to shorten the temporary roof and form an opening. However, since the maximum area that can be opened is less than half of the total area of the roof with the sheets stretched, that is, the roof, the opening cannot be structurally enlarged, and it is difficult to carry in long materials. However, there is a problem that efficient work cannot be performed because the place of loading is limited.

In addition, in the case of this invention, since a plurality of steel pipes are used, and if the opening area is increased as much as possible, the entire width of the roof frame becomes long, so that the volume and weight of the components of the roof increase. In addition, there were inconveniences such as large transport and assembly work.
