Description

[Detailed Description of the Invention] This invention relates to a film locking member for a greenhouse, etc., which fixes a film when a transparent vinyl sheet or the like is stretched on the roof or side wall of an agricultural or horticultural greenhouse.

Generally, in growing and cultivating this type of agricultural products, synthetic films such as vinyl are often pasted onto frameworks assembled from various types of shaped steel or steel pipes. However, this vinyl sheet suffers from a significant disadvantage in that it easily cracks from the point of attachment when exposed to rainstorms.

Therefore, a support frame is fixed to the framework of the greenhouse, etc., a vinyl sheet is laid on top of it, and then a metal locking line is fitted onto the support frame from above to secure the frame, but in this case, The metal locking line comes into direct contact with the vinyl, so it easily tears, and the metal locking line easily rusts due to rainwater, etc., contaminating the vinyl.

In addition, some conventional methods have been seen in which a metal locking line is inserted into a soft bag, and this is fitted into a support frame when the vinyl is expanded, but in this case, it serves as a buffer and prevents rust. Although the purpose of securing the bag is achieved, the problem is that the locking line rubs inside the soft bag and is easily damaged, and it takes a lot of time and effort to manufacture and install it. Since it expands and contracts inside, it is easy to separate from the bag, making it impossible to use it again.Furthermore, since the locking line is long, it takes a lot of effort and time to manufacture.

This invention is intended to solve each of these drawbacks, and its main structure is that the locking member is composed of a curved line and a synthetic resin band, and both are extruded. It is joined and welded to only one side of the surface, and both longitudinal sides of the strip are welded to only part of the outer periphery of the vertical sides located on both longitudinal sides of the locking member. Therefore, according to this invention, the vinyl sheet is compressed in a cushioning manner, and
It can fully handle the tensile action of vinyl, and has the effect of reliably preventing damage due to tearing, etc. In addition, since the locking member uses a synthetic resin strip on only one side of the surface, it saves on the construction material, and the internal curved line is not exposed to rainwater directly, so it prevents rust etc. It has the effect of preventing

Next, one embodiment of this invention will be explained with reference to the drawings.
A vinyl sheet 7 is appropriately laid on the support frames 8, 8, and the vinyl sheet 7 is press-fitted to the support frame 8. The locking member 1 is formed by welding a synthetic resin band 3 and a bent metal wire strip 2 by extrusion molding. Said bending line strip 2
The vertical sides 5, 5 and the inclined sides 6, 6 are continuously bent in the longitudinal direction using a metal wire to form a trapezoidal or wavy shape. Synthetic resin strip 3
is joined and welded to only one side of the surface of the bending line strip 2, but it forms substantially semicircular concave bulges 11, 11 on both longitudinal sides thereof, and the vertical sides 5, 5.
In the part 4, the welded part 4,
4 is integrally formed. 7 is a vinyl sheet laid in the greenhouse 13, 9 is a recessed part provided inside the support frame 8 in the longitudinal direction, and 10 is a curved part provided at the upper end of the rising side wall of the recessed part 9. .

This invention has the above-mentioned structure, and to explain how to use it now, the vinyl sheet 7 is laid on the support frames 8, 8 fixed on the frame beams 14, 14 of the greenhouse 13, and the vinyl sheet 7 is secured from above. By slightly tilting or pulling the members 1, 1 and pushing them into the recessed fitting parts 9, 9 from above the vinyl sheet 7 to the supporting frames 8, 8, the vinyl sheet 7 can be spread. The time locking member 1 acts elastically and comes into close contact with the inside of the recessed fitting parts 9, 9 to securely fix the vinyl sheet 7. Next, when removing the attached vinyl sheet 7, pull the ends of the locking member 1 outward one after another.
The band-shaped body 3 and the bending line strip 2 extend as one body against the impact, and as soon as they are detached from the support receiving frame 9, they are restored to their current state and can be used again.

As described above, according to this invention, it is extremely easy to stretch the vinyl sheet, it can be freely re-stretched, there is no damage to the vinyl sheet, the construction is quick and reliable, and the work efficiency is improved. Since the locking member is manufactured by extrusion molding of the bent line strip and the synthetic resin strip, it is easy to produce long objects that are continuous in the longitudinal direction, and the production capacity is significantly improved. is welded and adhered to the curved line, and the two are tightly integrated and easily separated, resulting in a worry-free effect. In addition, since the longitudinal sides of the strip are coated with the outer sides of the vertical sides located on both longitudinal sides of the locking member, the metal surface of the vertical sides does not come into direct contact with the vinyl sheet.
This has the effect of preventing the vinyl sheet from being damaged such as tearing, and the effect of buffering the space between the vinyl sheet and the vinyl sheet. Furthermore, since the outside of the surface of the strip is attached to the vertical sides of the bent line strips, the vertical sides of the bent line strips are not exposed to wind and rain directly, preventing the occurrence of rust, etc., and can be used for a long period of time. It would be effective if the material constituting the strip could be significantly saved and provided at low cost. In addition, the bulging portion of the strip has a portion where the bent lines are not alternately buried between the vertical sides, so the strip is press-fitted into a support frame of a greenhouse or the like. Sometimes, the part that is not buried is easily bent and deformed, making insertion extremely easy.

In addition, the approximately semicircular concave bulges formed on both sides of the strip have the effect of being able to press the entire vinyl sheet and securely lock it, and the effect of reliably preventing loosening due to tension due to wind pressure. be.
