DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film stopper provided for stretching a plastic film as a covering material for a greenhouse, and more particularly, to a film stopper between a base member fixed to the greenhouse. The present invention relates to a holding member that sandwiches and fixes a plastic film and forms a film stopper together with the base member.

2. Description of the Related Art As a film stopper for stretching a plastic film which is a covering material for a greenhouse, the present applicant has previously filed Japanese Patent Application Nos. 10-106122 and 10-106.
No. 148 was processed to have a base member having a side plate portion having a predetermined interval between upper end edges, an insertion portion inserted between the side plate portions, and a protrusion extending from the insertion portion. There has been proposed a plastic film stopper comprising a plate-like member and a holding member for holding the plastic film by inserting the insertion portion between the side plates of the base member. Since the plastic film is sandwiched between the base member and the insertion portion of the holding member, there is an advantage that the contact area is large and local wear of the plastic film can be prevented.

[0003] In particular, in recent years, polyolefin-based plastic films, not vinyl films, have become widespread because they have excellent weather resistance, do not generate harmful gases when burned, and are easy to dispose of. The film has a problem that it is more susceptible to abrasion than a vinyl film. Therefore, the above-mentioned film stopper is extremely effective as a stopper for such a polyolefin-based plastic film.

[0004]

In the above-mentioned film stopper, not only the base member fixed to the greenhouse but also the holding member is formed from a metal material such as aluminum.
It is always desirable to reduce manufacturing costs. Moreover, since it is molded from a metal material, there is a problem that it is difficult to dispose it along the arch (curved surface) of the greenhouse.

On the other hand, in order to reduce the manufacturing cost, it is conceivable to form the holding member from a synthetic resin. In this case, however, there is a problem that the holding member is inferior to the case where the holding member is formed of a metal material. .

It is formed wider than the gap between 2a. Therefore, when the base member 3 is inserted between the side plates 31, 32 through the gap between the opposed upper edges 31a, 32a of the base member 3, as shown in FIG. 14 is inserted so as to be rotated about the fulcrum. Since the width of the insertion portion 11 is wider than the gap between the upper edges 31a and 32a of the side plate portions 31 and 32 constituting the base member 3, the insertion portion 11 is once inserted between the side plate portions 31 and 32 and then remains as it is. If you try to pull straight up,
a, the inwardly protruding portion 12, which protrudes inward from 11b,
13 contacts the upper end edges 31a and 32a of the base member 3, so that it cannot be pulled out.

As described above, the inward projecting portions 12 and 13 project inward from the upper ends 11a and 11b of the substantially U-shaped insertion portion 11 by a predetermined width. The constricted portion 1 is bent upward from the inner end, more precisely, obliquely upward.
4, 15 are extended. The constricted portions 14 and 15 expand so as to be separated from each other when a fixing member 20 described later is loaded, and the outer surfaces thereof are formed on the upper ends 31 a and 3 of the base member 30.

When the insertion portion 11 is inserted between the side plate portions 31 and 32 of the base member 3, the lower surfaces of the flange portions 16 and 17 are formed at upper edges 31 a and 3 a of the base member 3.
It is provided so as to be in contact with 2a.

The fixing member 20 is provided with the above-described constricted portion 14,
Any material may be used as long as it can be inserted between the holes 15 and press the outer surfaces of the constricted portions 14 and 15 against the upper edges 31 a and 32 a of the base member 3. In the present embodiment, since the constricted portions 14 and 15 extend obliquely upward from the inwardly protruding portions 12 and 13, as shown in FIGS. 2 and 4, a substantially inverted triangle is formed so as to match this shape. It has a processed pressing portion 21. Also,
From both upper sides of the pressing portion 21, projecting pieces 22, 2
3 are protruded, and engaging claws 21 a and 21 b with upwardly sharpened tips are formed on both side surfaces of the pressing portion 21.

When the pressing portion 21 is loaded between the constricted portions 14 and 15, the protruding pieces 22 and 23 are moved to the flange portions 16 and 23.
As shown in FIG. 5, the protrusion widths of the projecting pieces 22 and 23 are made larger than the widths of the flange portions 16 and 17 so that all the upper surfaces of the flange portions 16 and 17 are formed. If it can be covered, it contributes to preventing weather resistance deterioration of the main body member 10 made of a synthetic resin. For this reason, as shown in FIG.
Near the outer end 22a, 23a is the flange 16,
More preferably, it has a shape that hangs down so as to cover the outer end surface of the 17.
