Embodiments of the present invention will be described below with reference to the drawings. <A> Supporting device The supporting device 1 is for erection of a main cable. For example, as shown in FIGS. 1 and 2, two long and short columns 1a and 1b are erected in an X shape. Two units are installed facing each other across the outdoor facility A. Both pillars can be opened and closed by a hinge structure, and the inclination can be arbitrarily changed.

As an opening and closing structure of the columns 1a and 1b, for example, as shown in FIG. 2, both columns are mounted on a traveling gantry 11, and the gantry 11 is configured to be able to travel on a rail 12. Conceivable.

The X-shaped columns may have a fixed structure.
In addition, not only the X-shape but also two long and short columns may be installed upright. Further, the main cable may be directly installed on the outdoor facility, or may be installed on other members other than the pillar.

<B> Main Cable The main cable 2a is provided between the tip of the support 1a and the main cable.
The bull 2b is installed in a substantially horizontal direction between the front ends of the columns 1b. As shown in FIG. 2, both ends of the main cables 2a, 2b are wound around winders 3a, 3b mounted on a traveling gantry 11 via pulleys at the tips of the columns 1a, 1b.

<C> Sub-cable A plurality of sub-cables 4a are provided in a direction intersecting the main cable 2a with one end connected to the main cable 2a, and passing above the main cable 2b. Is wound around a winder 5a. On the other hand, sub cable 4
b, one end is connected to the main cable 2b,
A plurality of cables are arranged in a direction intersecting with the cable 2b, and the other ends thereof are wound around a winder 5b under the main cable 2a.

<D> Film body The film body 6a is composed of sub-cables 4a, 4a
It is stretched between and has a belt-like shape or the like. As shown in FIGS. 3 and 4, the longitudinal edge of the film body 6a is a runner-61.
Slidably attached to the sub-cable 4a via
Only the first runner 62 on the main cable 2a side is a sub cable.
Bull 4a.

As shown in FIG. 4, a tension cable 63 is connected to the runner 61 on the winding machine 5a side, and when the roof is closed, the winding machine 5a side of the film body 6a is rolled up together. Pull so that there is no.

Further, as shown in FIGS.
A weight 64 may be provided along the longitudinal direction at the center of the, and a drainage function as a gutter can be provided in rainy weather. The film body 6b is similarly stretched between the sub-cables 4b and 4b. As a result, a roof structure composed of a group of film bodies 6a and 6b having a shape in which the main cable side is wrapped is completed.

<E> Dual film structure As shown in FIG. 3, since a gap is formed between the film members 6a, 6a, the film member 7a can be wrapped at the lower or upper part to form a double structure. In this way, the effect of preventing wind, rain and sunlight can be enhanced. The structure of the film body 7a is the same as that of the film body 6a.

[0023]

Operation As shown in FIG. 1, the main cables 2a, 2b
Is wound up and the sub-cables 4a and 4b are sent out, whereby the roof composed of the group of membranes 6a and 6b is closed. In order to open the roof, as shown in FIG. 6, each of the winders is operated to send out the main cables 2a and 2b and to wind up the sub-cables 4a and 4b. it can.

[0024]

Other Embodiments In the above embodiment, a roof with a double-sided structure is used. However, a roof with a single-sided structure is also possible if, for example, only the membranes 6a are used. A roof structure in which three or more roof structures are installed by wrapping a membrane body and opened and closed in multiple directions is also possible. Furthermore, in the case of a large roof, between the columns of the main cable,
In some cases, additional columns may be added.

As shown in FIG. 7, the main cables 7a, 7b,... Are provided in a plurality of layers, and a plurality of sub-cables 71 disposed in the main cables of each layer are provided.
It is also conceivable that the film bodies 72 are mounted at intervals and the film bodies 72 positioned above and below are shifted and mounted. In this case, sunlight, air conditioning, and the like can be more finely adjusted.

Referring to FIG. 3, the end of the film body 6a on the winder 5a side is fixedly attached to the sub-cable 4a, and the sub-cable 4a and the film body 6a are integrally wound. In the case of a configuration in which the film can be sent out, or the first runner-62 of the film body 6a
May be slidably mounted along the sub cable 4a, and only the film body 6a may be expanded and contracted with the sub cable 4a stretched.

Further, as shown in FIG.
In some cases, a membrane is attached to the bull. That is, the main case
The bull 8 is erected between the columns 81 and both ends thereof are taken up by a winder 82.
And a sub cable 8 in the middle of the main cable 8.
3 is provided, and the film body 84 is directly fixed and attached to the main cable 8 and the sub-cable 83. In this case, reinforcing members 85 are attached to both edges of the film body 84, and the intermediate portion of the film body 84 is squeezed by the pulley 86, and then the winding machine 8
7.

As shown in FIG. 9, two layers of main cables 9a and 9b are provided with sub-cables 91a and 91b, respectively, on the same side, and two sides of a film body 92a and 92b such as a right-angled triangle are formed. Main cable 9a, 9b and sub cable 9
1a, 91b attached and stretched, winding each cable,
It is also conceivable that one side can be opened and closed by feeding.

Further, when the scale of the whole roof or one membrane is small, the sub-cable is not provided and the main case is not provided.
It is also possible to attach the membrane body directly to the bull and wind and feed the membrane body itself to open and close the roof.

[0030]

Since the present invention has been described above,
The following effects can be obtained. <A> It has an extremely simple and lightweight structure composed of a main cable, a sub cable, and a membrane, is low in cost, and requires no air conditioning equipment.

<B> Due to the simple structure, retrofitting to an existing facility can be easily performed.

<C> Since the shape of the cable and the membrane is easy to change, the shape of the entire roof can be arbitrarily configured, and design elements can be easily added.
