It is necessary to prevent rainwater from entering. For this reason,
Conventionally, the film bodies 1 and 1 are joined by the method shown in FIG. 5, for example.

That is, the respective end portions of the film bodies 1 and 1 to be joined are joined together by the lacing method, and a pair of joint membranes 2 are branched from the connecting end portions of the film bodies 1 and 1 in a bifurcated manner. , 2 are provided so that the end portions of the joint films 2 and 2 are fused.

The lacing method in which the ends of the film bodies 1 and 1 are joined to each other is, as shown in FIG. 6, the eyelets 3 are provided alternately at the ends of the film bodies 1 and 1 at regular intervals. This is a method of sewing the eyelet 3 with the string 4.

[0007]

However, in such a conventional joining structure of the film bodies, as described above, when the film bodies 1 and 1 are joined by the lacing method,
In order to make the gap between the membranes 1 constant, the sewing force of the string 4 is made uniform over the entire length of the connection end portions of the membranes 1 and 1, and the tension acting on the membranes 1 is evenly received by each eyelet 3. Need to have. Therefore, when sewing between the eyelet 3 with the string 4,
You must sew from the end in order and with equal force,
There has been a problem that this sewing work becomes extremely difficult and takes a lot of time.

In view of the conventional problems, it is therefore an object of the present invention to provide a film body connection structure capable of easily and rapidly joining film bodies.

[0009]

In order to achieve such an object, the present invention provides a connecting member having hooks at both ends directed in opposite directions to each other and having a substantially S-shape, and the hook of the connecting member is provided. A structure is adopted in which the film body to be connected is inserted into the facing mounting holes formed at the connection ends of the film bodies to be hooked.

Further, in such a configuration, it is desirable that the connecting members are arranged in appropriate numbers with respect to the connecting members to be provided so that the inserting directions of the hooks are opposite to each other.

[0011]

In the structure for connecting a film body according to the present invention having the above-described structure, the hooks formed at both ends of the connecting member are inserted into the mounting holes at the connection ends of the film body to be hooked. Membranes can be connected to each other. Therefore, the membrane members can be connected by simply inserting the attachment holes into the hooks, and the connecting work can be remarkably simplified and the work can be performed quickly. Further, since the hooks at both ends of the connecting member are formed in a substantially S-shape by directing the hooks at opposite ends thereof in opposite directions, the hooks of the pair of hooks at opposite ends are hooked to the film body in mutually opposite directions. Even when the connected film body is swung by wind or the like, it is possible to make it difficult to remove the hooked portion.

[0012] Further, by appropriately arranging the connecting members with respect to the connecting members to be provided, the hooks of the connecting members which are arranged in reverse are hooked from both sides of the film body. Since it can be stopped, the hooking portion can be made more difficult to detach.
