Description

[Detailed Description of the Invention] The present invention relates to a film fixing device for greenhouses for agriculture and horticulture.

Conventionally, this type of film fixing device has a cylindrical shape with an opening extending in the length direction, and is designed to be fitted onto the aggregate of a vinyl greenhouse via a film. However, such fixing devices only fix the stretched film to the aggregate, so when the film is pulled up along the aggregate to ventilate the greenhouse, the film is held in the lifted position. This had the disadvantage that ventilation work was time-consuming. In addition, since such fixing devices cannot hold the film that has been lifted up during ventilation, the film is held down using a film holding band, or a separate support is used to support the film so that it does not fall off. The retention was insufficient, and the film easily slipped off due to wind pressure, etc.

In view of the current situation, the present inventor has made efforts to
The object of the present invention is to provide a film fixing tool for a vinyl greenhouse that eliminates the above-mentioned drawbacks.

The present invention will be described below with reference to the drawings.

In the drawings, A is the fixing device of the present invention, which is composed of a main body 1 and a hook portion 2. Fixture A is made of synthetic resin, metal, or the like.

The main body 1 has a cylindrical shape with an opening 11 extending along its length, and has elasticity so that it can be removably fitted onto the aggregate 3 of a vinyl greenhouse.
Further, it is preferable that reinforcing ribs 12 are provided on the outer circumferential surface of the main body 1, since the fitting with the aggregate 3 can be made strong and the strength of the main body 1 can be improved.

The hook part 2 is connected to the main body 1 from the back side of one end of the main body 1.
It protrudes in the opposite direction, and is curved into an arc so that the middle part is once away from the extension line of the axis of the main body 1 and the end part approaches the extension line again. That is, the hook portion 2 is usually formed into a curved plate shape as shown in FIG. 1, so that when the main body 1 is fitted onto the aggregate 3, the curved top portion rises from the outer surface of the aggregate 3. Further, the curved end portion of the hook portion 2 is configured to substantially contact the outer surface of the aggregate 3 when the main body 1 is fitted onto the aggregate 3.

Therefore, the fixing device A of the present invention is fitted onto the aggregate 3 of a greenhouse through the film 4, and the film 4
and when ventilation the greenhouse, use a third
As shown in the figure, the fixing tool A is fitted onto the aggregate 3 with the hook part 2 facing upward, and the end edge of the film 4 is slid up along the aggregate 3, and the hook part 2 and the aggregate are curved into an arc. 3 to hold the film 4.

Alternatively, the fixing device A of the present invention may be fitted onto the aggregate 3 with the hook portion 2 facing downward, and the film presser band 5 may be hooked onto the hook portion 2 to be used for fixing the film presser band 5. good.

As detailed above, the film fixing device of the present invention has a hook part that protrudes from one end of the back side of the main body in the opposite direction of the main body, so that the main body does not become stiff when holding the hook part by hand. The main body can be easily attached and detached from the greenhouse aggregate, and the hook part is easy to grip, especially when removing it from the aggregate, resulting in good workability.

In addition, in the film fixing device of the present invention, the hook part is curved in an arc so that the middle part is once away from the extension line of the axis of the main body and the end part approaches the extension line again, so that the hook part faces upward. When the main body is fitted onto the aggregate, a semicircular gap is formed between the hook part and the aggregate, and even if the edge of the film that is lifted up during ventilation in the greenhouse becomes bulky, the semicircular gap will be formed between the hook and the aggregate. By forcing the film into the gap, the gap between the end of the hook part and the aggregate is narrowed, so the packed film does not fly out, and the film can be firmly supported in the lifted state.

Furthermore, by fitting the main body onto the aggregate with the hook portion facing downward, a film holding band can be hooked onto the film portion and used as a fixing device for the band.
