Abstract

PURPOSE: To enhance durability against external pressure by sewing frame tubes, into which frames for making a tent self-support are inserted, to the film of the tent in such a way as to provide a triangular cross section. CONSTITUTION: Frame tubes 12 are so formed to provide an approximately triangular cross section with a tape of cloth and a film 11 and to make a tent high at its center as seen from its longitudinal direction and decrease in height toward both ends. To erect the tent, frames 13 are inserted into the frame tubes 12 and secured to the corners of the film 11 at their ends. Since the frames 13 are longer than the diagonals of the film 11, they are curved when secured to the corners of the film at both ends, and thus impart tensile forces to the film 11 and the frame tubes 12 simultaneously to allow the tent to self-support. The frame tubes 12 are pulled upward by the force with which the frames 13 curve, the frames 13 are thereby located at the apex of the triangular shape, and the right and left side films of the tubes and the apex of the film 11 form stretched beams of a triangular structure, so as to provide a structure preventing horizontal deformation.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to tents and more particularly to camping tents.

[0002]

2. Description of the Related Art FIG. 4 shows a conventionally known camping tent. The material of the tent is a film body 1 whose plane shape is rectangular.
The frame 2 is longer than the diagonal length of the membrane 1, and the membrane 3 is sewn with the tube 3 diagonally. To assemble the tent, the frame 2 is inserted into the tube 3 and the ends are fixed to the corners of the film body 1. Since the frame 2 is longer than the diagonal length of the film body 1, when the frame 2 is fixed to the corner of the film body 1, the frame bends, and the self-standing tent 4 is formed as shown in FIG. 4A.

The tube 3 according to the prior art has a problem that the assembled frame 2 is easily moved to the left and right and is weak against external pressure because the connecting portion with the film body 1 is sewn at only one point as shown in FIG. 4C. There is. For example, when external pressure is applied to the tent 4 from above, the tent may be deformed and crushed while rotating to the left or right.

Camping tents are used throughout the four seasons, and their deformation and crushing, especially during the snowy season, poses a serious problem affecting human lives.

[0005]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a camping tent which is durable against external pressure such as strong wind or snow.

[0006]

Means for solving the problems in the present invention include a film body, a frame tube provided on the film body, and a frame tube inserted into the frame tube and stretching the film body. In a tent composed of a frame for installation, the frame tube is sewn to a film body so as to have a triangular cross section.

1 to 3 show an embodiment, FIG. 1 is an overall perspective view, FIG. 2 is a perspective view of a tent top, and FIG. 3 is a sectional view of a frame tube.

In these figures, the tent 10 is a membrane body 1.
1, a frame tube 12 sewn on a diagonal line of the film body 11, and two frames 13 which are a frame of a tent.

The film body 11 of the tent uses a woven cloth made of nylon thread having a rectangular shape in plan view and having high tension. The frame tube 12 is formed by a tape-shaped cloth and a film body into a substantially equilateral triangular cross section.
The frame tube 12 is formed such that the height of the frame tube 12 in the longitudinal direction is higher in the central portion of the tent and lower toward both ends. The frame 13 is to be inserted into the frame tube 12, is longer than the diagonal length of the film body 11, and is made of duralumin, which is rigid but elastic.

In the embodiment, the frame tube 12 is not provided up to the corner of the film body 11, but this is in consideration of the ease of assembling the tent.

The frame tube 1 is used to assemble the tent.
The frame 13 is inserted into the frame 2 and the ends are fixed to the corners of the film body 11. Since the frame 13 is longer than the diagonal line of the film body, when both ends are fixed to the corners of the film body, the frame 13 bends, and at the same time, the film body 11
Also, tension is applied to the frame tube 12 to make the tent self-supporting.

Since the frame tube 12 is pulled upward by the bending force of the frame 13, the frame tube 12 has a triangular cross section as shown in FIG. 3, and the frame 13 is located at the top of the triangular shape. Therefore, the frame tube 12
Forms a tension string beam with a triangular structure by the left and right tube side films 12A and 12B and the top film 11A of the film body 11,
The structure prevents deformation in the left-right direction.

That is, when external pressure is applied to the tent from above, the tent tries to deform while twisting in either the left or right direction, but in the embodiment, the frame tube 12 is opposed to the external pressure in the left and right directions. The side film 12A or 12B on the side and the top film 11A of the film body 11 oppose each other to prevent twisting of the tent and prevent deformation of the tent. Further, since the frame tube 12 has a structure in which the central portion along the longitudinal direction is high and is lowered toward both ends, the central portion of the tent is reinforced by the principle of the beam structure, so that it is difficult to deform due to external pressure. .

In FIG. 1, reference numeral 14 designates an entrance / exit of the tent 10, which is provided with a fastener at its peripheral edge so as to be freely opened and closed.

In the embodiment, the film body 11 of the tent 10 is formed in a rectangular shape, and the frame tube 12 is sewn in a crossed shape by connecting diagonal lines. However, the film body 11 is not limited to a rectangular shape, and various shapes can be selected. it can. Also, frame tube 1
It is not limited to the shape in which 2 is crossed.

[0016]

According to the present invention, since the frame tube for inserting the frame for making the tent self-supporting is sewn to the tent membrane so as to have a triangular sectional shape, the tube side membrane and the membrane top membrane are sewn. The triangular structure due to prevents the tent from twisting and makes it durable against external pressure.
