Description

[Detailed explanation of the invention] [Industrial application field] This invention is applicable to tennis courts, swimming pools, exhibition halls,
Or it relates to a tent that is installed and used in a relatively large tank or the like.

[Conventional technology]

In general, for a tent in which tent cloth is stretched between a pair of left and right rails so that it can be unfolded and stored, for example,
There is a tent-type wood storage warehouse described in Utility Model Publication No. 57-55842.

The above-mentioned tent-type wood storage warehouse has a pair of left and right rails with an approximately I-shaped cross section arranged in parallel at a required height via supports, and a required number of support frames are installed between the rails with a traveling device so that they can move freely. A tent cloth is stretched between each frame so that it can be unfolded and stored.

[Problem that the invention attempts to solve]

However, since the conventional product configured as described above uses ribs as the tent core material, the tent cannot be made into a long span.

Since the ribs themselves are not flexible, the tent tends to have a so-called rigid structure, which is easily damaged by excessive force caused by gusts or strong winds.

When the tent is deployed, tensile force is applied directly to the tent fabric itself between the ribs, which tends to damage the tent fabric.

The weight of the tent structure itself becomes large.

Since the ribs are used as the tent core material, they are heavy and bulky, making it extremely troublesome to transport materials during installation.

There were other problems.

This idea solves the problems of conventional products all at once.
To provide a tent that is not only lightweight and has a flexible structure, but also has a long span, is extremely durable, and is convenient to transport.

[Means for solving problems]

That is, this invention provides a tent in which tent cloths 9 and 19 are stretched between a pair of left and right rails 1 arranged parallel to each other at a required height so that they can be unfolded and stored, and the rails 1 have a substantially C-shaped cross section. and each rail 1
An endlessly driven winding power transmission node 3 is inserted into the interior of the winding power transmission node 3 in a freely movable manner via a runner 7, and wire-like flexible tent core materials 6 are inserted at predetermined intervals between the winding power transmission nodes 3. The tent has rope-like flexible spacing members 8 installed at predetermined intervals between the tent core members 6.

[Effect]

A pair of left and right endlessly driven winding transmission nodes 3 are allowed to run forward and backward at a synchronous constant speed along the inner surface of a rail 1. Then, the tent core material 6 is pulled by the running of the winding transmission link 3, and the tent cloths 9, 19 are unfolded and stored. At this time, the tensile force of the tent core material 6 is directly transmitted to the spacing member 8, and the tent cloth 9,
19 are deployed and stored regularly and always at predetermined intervals.

〔Example〕

An embodiment of this invention shown in the drawings will be described below.

1 to 3 show a first embodiment, and in the figures, reference numeral 1 denotes a rail having a substantially C-shaped cross section, which is arranged in parallel at a required height via a support 2;
Reference numeral 3 denotes an endlessly driven winding power transmission node that is inserted into each rail 1 so as to be able to circulate freely, and the winding power transmission node 3 is composed of a wire, a chain, a rope, a belt, or the like. Reference numeral 4 denotes a pair of transmission wheels on both sides around which the wrapped transmission link 3 is wound, 5 is a motor connected to one of the transmission wheels 4 and is rotatable in forward and reverse directions, and 6 is a runner 7 between the wrapped transmission link 3. The tent core material 6 is constructed at predetermined intervals through the tent core material 6.
is made of a flexible material such as wire. Reference numeral 8 denotes a flexible spacing member such as a rope, which is installed in a substantially lattice shape at predetermined intervals between the tent core materials 6, and 9 is a roughly wave-shaped tent stretched between the tent core materials 6. cloth, the tent cloth 9 is the second
As shown in the figure, it is of medium height and slopes toward both side edges.

Next, the operation of the tent according to this invention will be explained.

First, when unfolding the tent, it is preferable to start the motor 5 in normal rotation. Then, the transmission wheel 4 rotates to cause the winding transmission section 3 to travel along the inner surface of the rail 1, and the tent core material 6 is sequentially pulled and the tent cloth 9 begins to unfold. At this time, the tensile force of the tent core material 6 is directly transmitted to the spacing member 8, so that the tent cloth 9 can be unfolded regularly at predetermined intervals without applying excessive force to the tent cloth 9. When the tip of the tent cloth 9 reaches the end of the rail 1, the motor 5 is stopped and the tent is completely expanded. In addition, when unfolding the tent, the tent cloth 9
The building is medium-high and slopes toward both edges, allowing for good drainage of rainwater. Further, since the tent core material 6 and the spacing member 8 are flexible, the tent has a so-called flexible structure, and can resonate even under strong winds.

On the other hand, when storing the tent, it is preferable to start the motor 5 in reverse, make the winding transmission link 3 travel in the opposite direction, and store the tent cloth 9.

4 and 5 show the second embodiment,
This is different from the first embodiment in that the tent cloth 19 is formed in the shape of an airtight air bag with ventilation holes, and the tent core material 6 and the spacing member 8 are arranged inside the tent cloth 19 in a lattice shape. Other parts are the same, and the same reference numerals indicate the same parts.

[Effect of idea]

According to this invention, as described above, the winding power transmission joints 3 are inserted through the runners 7 into the left and right pair of rails 1 having a substantially C-shaped cross section in a freely movable manner. Since a wire-like flexible tent core material 6 with tent cloth 9 stretched between each tent is installed, the tent can be automatically unfolded and stowed by running the winding transmission link 3. In addition, between each tent core material 6, space maintaining members 8 having rope-like flexibility are provided at predetermined intervals.
is constructed, the tensile force accompanying the running of the winding transmission link 3 is transmitted to each spacing member 8 via the tent core material 6, so that the tent can always be opened and closed regularly at predetermined intervals. Not only is this possible, but since the tensile force accompanying the running of the winding transmission link 3 is not directly transmitted to the tent cloths 9, 19, there is almost no damage to the tent cloths 9, 19, and the tent cloths 9, 19 can withstand long-term use. . Furthermore, the tent core material 6 has wire-like flexibility, and the spacing member 8 having rope-like flexibility is installed between the tent core materials 6, so that the tent structure has a so-called It has a flexible structure, so there is no risk of resonance and excessive force being applied even under strong winds, and it is extremely durable.
It is lightweight and allows the tent to have a long span.
