Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relatively large and sturdy novel folding type bellows type tent which is useful for a work place of civil engineering and construction, concrete curing, etc. and which has a feature particularly in a frame portion.

[0002]

2. Description of the Related Art In order to set up a relatively large tent in a remote place, in order to carry a required frame construction member which is heavy and bulky, assemble it, further coat a film-like material, and further withdraw it. However, a large number of personnel and man-hours are required, but none of the conventional products sufficiently satisfies such conditions. Therefore, there has been a strong demand for the appearance of a large tent that can be quickly erected, is sturdy, is relatively easy to disassemble and remove, and is large.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and is capable of being folded and easily transported, and can be quickly erected on site.
Further, it is an object of the present invention to provide a tent having sufficient strength so that the beam portion can be contracted or released in a bellows type so as to facilitate transportation and extension, and the legs can be smoothly constructed so that the legs can slide on the rails. It is a thing.

[0004]

The present invention comprises: a. A main beam part which is provided on the front and rear girders, which is formed by arranging a transverse joint material on two bases having legs extending from both ends of a mountain-shaped roof beam and arranging the frame, and b. A plurality of intermediate beam portions that are formed in a generally inverted U-shape by connecting the roof beam and the legs and are arranged in parallel between the both main beam portions; c. An X-shaped bar that is openably and closably connected between each main beam portion and an adjacent intermediate beam portion and between each adjacent intermediate beam portions, d. Both main beam portions and each intermediate beam portion are inwardly foldable at the upper portions of their respective legs, and e. Bearings are mounted at the respective leg ends so as to straddle an I-shaped rail and slide on the rails. F. Lifting pipes capable of loading and unloading the whole are fixedly installed on both main beam parts, g. Further, it is configured to have a film-like material covering the roof and side surfaces of the extended frame and the wife. H. The folding type bellows type tent is established as its gist.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view showing a folded and suspended state of a tent according to the present invention, FIG. 2 is a side view showing a vehicle mounted state of the tent, and FIG. 3 is a vehicle mounted state of the tent. FIG. 4 is a side view showing the unloaded state of the tent, FIG. 5 is a side view showing the extended state of the frame of the tent, and FIG. 6 is the extended tent. 7 is a front view showing the frame end portion of the tent, FIG. 7 is a side view showing the open state of the intermediate beam portion of the tent, and FIG. 8 is a view showing bearings at each end of the main beam portion and the intermediate beam portion of the tent. It is sectional explanatory drawing which shows the relationship with a rail.

FIG. 1 shows a state in which a tent according to the present invention is folded and suspended. The frame of the tent of the present invention has main beam portions 1 and 2 at both ends, as will be described later in detail.
And a plurality of intermediate beam portions 3, 4, 5 arranged in parallel between
The main components are 6, 7, 8, and 9. The intermediate beam portion is contracted during transportation as illustrated. The main beam portions 1, 2 and the intermediate beam portions 3, 4, 5, 6, 7, 8, 9 have rails 10 at their ends.
Riding on top of. FIG. 2 shows a state in which the product of the present invention is folded inward at the bent portions 11 and 12 at the upper portions of the respective legs and mounted on the transport vehicle 13.

FIG. 3 is an explanatory view showing the mounted product of the present invention. Main beam portions 1 and 2 are provided on both sides, and intermediate beam portions 3 to 3 are provided at the center.
9 is shown in a contracted state. When the installed tent according to the present invention arrives at the installation place, wire ropes are passed through the hoisting pipes 14 and 14a fixed to the main beam portion, and the hoist is unloaded by a crane or the like. In the main beam portion and the intermediate beam portion, the respective leg portions rotate in the arrow direction toward the standing state. In FIG. 4, the legs 1a and 1b of the main beam 1 are shown rotating in the directions of the arrows. Leg 1a,
In the case of standing, 1b straddles the rail as will be described later, but at the time of mounting / unloading, casters can be attached / removed to / from the end portions of the front and rear main beam portions for convenience of movement. 15,
16 is attached. Although not shown, the same applies to the case of the main beam portion 2.

FIG. 5 shows a state in which the product of the present invention is deployed on the rail 17. The main beam portions 1 and 2 and the intermediate beam portions 3 to 9 at both ends straddle each rail end portion on the rail 17 and slide on the rail. The rail 17 is usually mounted on a pedestal 18. The main beam portions 1 and 2 are mountain-shaped roof beams 19 shown in FIG.
Bases 22 and 2 on which legs 20 and 21 are respectively hung from both ends of the
2 pieces of 2a are framed by laying the horizontal joint material 23,
They are placed in the front and back wife, respectively. The main beam portions 1 and 2 are between the adjacent intermediate beam portions 3 and 9, and each intermediate beam portion is between the adjacent intermediate beam portions, for example, 3 and 4, 4 and 5 ,. Openable and closable X-shaped vias 24, 25, ... Although not shown, a wire rope is stretched by connecting the tops of the roof beams and the tops of the intermediate beams of the main beams to keep the distances and intervals between the beams at the X-shaped aperture opening constant. Both legs 20 and 21 can be folded inward at the bent portions 11 and 12, respectively. A bearing 32 that slides on the I-shaped rail 10 is attached to the end of the leg. The mounting state is shown in FIG. Reference numerals 33 and 34 represent guide rollers.

Since the roof membrane of the film-like material covering the outside of the tent is attached to the main beam portion, the intermediate beam portion and the roof beam portion in advance at the portion 35 shown by the dotted line in FIG. 6, When the intermediate beam is opened, the contracted roof membrane extends and covers the entire roof. The lateral membrane is hung after the frame is developed. Usually, the side surface film is provided with a transparent portion to enhance the lighting effect. Further, since the gable film serves as an entrance / exit portion, it is preferable that the gable film is formed in a roll-up curtain shape that is convenient for opening and closing. The film body is required for the roof, the side surface, and the wife, but there is no particular limitation on the shape, attachment means, or the like.

[0010]

The present invention is based on the above-mentioned structure, and an important characteristic part is the frame part, and in particular, a plurality of intermediate beam parts are arranged in parallel between the main beam parts at both ends and are adjacent to each main beam part. The X-shaped bar that is openably and closably connected to the intermediate beam part and between the adjacent intermediate beam parts is provided so that each beam part slides on the rail at the end, and It is characterized in that the legs are formed so that they can be folded inward. Therefore, the tent can be transported to the construction site smoothly and reasonably in a compact shape, and the time and personnel required for the construction can be reduced, and the tent after construction can be securely fixed on the rail. Therefore, it is extremely tough against wind and snow and other external conditions, and is remarkably excellent when applied to construction sites and other outdoor sites, and can be said to be an extremely useful invention.
