Description

[Detailed Description of the Invention] The present invention relates to a fastener such as a film suitable for use in assembling an agricultural greenhouse.

As this type of fastener, there has conventionally been one shown in FIG. This is a structure in which a receiving groove 3 is formed by folding back side walls 2 that gradually incline upward and inward on both sides of a bottom plate 1. A plastic film 4 is stretched along the receiving groove 3, and a wire is meandered over the plastic film 4. The plastic film 4 is stopped by pushing in a pusher 5 (FIG. 2).

However, since this is simply a folding of the side walls 2 on both sides of the bottom plate 1, rainwater and water droplets that enter between the receiving groove 3 and the film 4 cannot flow out to the outside and accumulate in the receiving groove 3. It ends up. As a result, the fasteners are prone to rust and may even corrode from the rusted parts.
There was a problem with durability.

Also, in the past, there were some that had slits formed in the receiving material, such as the seat stopper of Utility Model 56-28651.
Since this slit is sized so that the peak of the locking line that is inserted into the receiving material can be fitted into it, the sheet is pushed outward from the slit by the locking line. This caused problems such as the sheet being easily bent or stretched. Furthermore, since the peaks of the locking wires fit into the slits, the slits are blocked by the peaks, so that water that has entered between the receiving groove and the seat can hardly escape through the slits.

The film fastener of the present invention solves these difficulties, and one embodiment thereof will be described with reference to FIG. 3 and the following drawings.

The present invention forms side walls 2 that gradually rise upward and inward on both sides of the bottom plate 1, forming a receiving groove 3 into which a corrugated presser 5 can be inserted, and extends from the bottom plate 1 to the side walls 2. A through hole 7 is formed in both the bottom plate 1 and the side wall 2 so that the ridge portion 8 of the pusher 5 cannot fit therethrough, and the through hole 7 is formed in both the upright portions 6 at appropriate intervals. It is formed by forming a large number of.

In this case, when the peak 8 of the pusher 5 fitted into the receiving groove 3 is located inside the through hole 7, the through hole 7
The film 4 pressed by the hole 7 closes the hole 7, and water cannot flow out from the hole 7. Therefore, in the present invention, the through holes 7 formed in the facing rising portions 6 are formed at positions facing each other, so that no matter where the pusher 5 is inserted into the receiving groove 3, either one of the facing through holes 7 is formed.
is made so that it always comes off from the crest 8 of the push tool 5. This prevents all of the through holes 7 from being blocked by the film 4 pushed by the peaks 8, making it impossible for water to flow out.

The diameter size, spacing, opening position, etc. of the through holes 7 may be other than those shown in FIG. Any material may be used as long as it allows the water to flow out easily and, moreover, when the pusher 5 is fitted into the receiving groove 3, the crests 8 of the pusher 5 are not located inside all the through holes 7 at the same time. Therefore, for example, the intervals between the through holes 7 may be made uneven.

3 to 5 have grooves 9 for screw fixing formed in the bottom plate 1, and the grooves 9 protrude from the front 10 side of the bottom plate 1 to the back 11 side.
This groove 9 may or may not be present.

Since the present invention is constructed as described above, it has the following various effects.

(a) Since the through hole 7 is open in both the bottom plate 1 and the side wall 2, rainwater and water droplets that have entered between the receiving groove 3 and the film 4 can easily flow out from the through hole 7. Because of this, we have never had a case where the stopper gets rusted due to moisture accumulation, or when the stopper corrodes due to rust.
It becomes a fastener with excellent durability.

(b) Since the through hole 7 is made so large that the crest 8 of the pusher 5 cannot fit into it, the crest 8 will fit into the through hole 7 and the sheet will be forcibly stretched and bent or thinned. There is nothing to do.

(c) Through hole 7 formed in opposing rising portion 6
is formed in a position that will not be blocked by the crest 8 of the push tool 5 fitted into the receiving groove 3, so no matter where in the receiving groove 3 the push tool 5 is inserted, the ridge of the push tool 5 will not be blocked. All of the through holes 7 are not blocked at the same time by the portion 8. Therefore, there is no need to perform positioning each time the pusher 5 is inserted into the receiving groove 3, and the work of inserting the pusher 5 into the receiving groove 3 becomes easier, and the agricultural house can be assembled in a short time. You can also do it.

(d) Since the through hole 7 is formed in the strong rising portion 6, the strength of the fastener will hardly decrease even if the through hole 7 is formed.
