Description

[Detailed description of the invention] This invention is used to fix a membrane material (covering material) such as a transparent or translucent plastic film to the building frame such as vinyl glass when constructing a vinyl house, etc. Regarding a fixing device.

BACKGROUND ART Due to its nature, hard membrane materials are susceptible to bending, and cracks are likely to occur at bent points, resulting in a loss of effectiveness as a covering material.

Therefore, conventional fixing devices used for soft film materials (for example, the one described in Japanese Utility Model Publication No. 48-37715).

) are not suitable for use. Conventionally, as a fixing device for hard film materials, for example, the device described in Japanese Utility Model Publication No. 49-5555 belongs to the public domain.

However, in this fixing device, the locking material constituting the fixing device has locking pieces arranged in parallel on one side of a flat plate-shaped base with buttons in the cross section and having a substantially V-shape, and the upper end of each locking piece. Because it has a structure in which a retaining bulge is formed on the side and a fitting recess is formed on the proximal side,
If the rigidity of the locking vertical piece is too thick, the resistance when fitting the fitting material into the fitting groove of the miscellaneous material becomes large, making it difficult to fix the hard film material.

Furthermore, there is a risk that the hard membrane material will be seriously damaged and its useful life will be lost.

On the other hand, when the rigidity of the locking vertical piece is low, the fixing force of the hard film material is weak and reliability is poor.

Furthermore, when fixing the hard film material, it is necessary to finally fasten the miscellaneous material at key points using a fastening tool, and the fixing work requires two wheels and is troublesome.

Purpose of the invention Therefore, the purpose of this invention was to create a system that is simple in structure, easy to use, particularly suitable for fixing hard film materials, has a strong and reliable fixing action on the film material, and also hardly damages the film material. It is an object of the present invention to provide a film material fixing device with an improved structure that can be used.

Structure and Effects of the Invention In order to achieve the above object, the film material fixing device of this invention has a dovetail groove-shaped membrane in which the supporting frame has a button on its cross section and both side walls are inclined to widen toward the end in the depth direction. Both opening edges of the membrane material fixing groove are curved, and the fitting member is; Almost close...
The membrane holding portions are symmetrically inclined in the shape of a square, and the upper portions of the left and right film holding portions are connected in series by an arcuate lid portion that is convex toward the upper side of the film material fixing groove. ing.

First, this fixing device attaches the support frame to a predetermined position on the vinyl house frame with the membrane material fixing groove facing outward, and spreads the membrane material that is the covering material of the vinyl house on the membrane material fixing groove. Then, when the membrane presser part of the fitting member is placed on top of the membrane material and pushed together with the membrane presser into the membrane material fixing groove on the support frame, the membrane material is held by using the elastic force of the fitting member. It can be established.

Therefore, the membrane material is fixed through the curved opening edge of the support frame and through the membrane pressing part of the fitting member, that is, it is fixed in a state where it is not subjected to excessive bending. Suitable for fixing.

But this i! It can also be applied to fixing soft film materials, that is, it can be used for both hard and soft purposes.

Further, this fixing device can completely achieve the purpose of fixing by a so-called one-touch operation of simply pushing the membrane pressing portion of the fitting member together with the membrane material into the membrane material fixing groove of the support frame.

Therefore, it is easy to use even for those without experience, and it does not require much effort.
Fixing work can be done very efficiently.

Furthermore, in this fixing device, since the fitting member has a structure in which the left and right membrane pressing parts are connected in series by the lid part,
By elastically bending the lid, fixing or unfixing of the film material can be easily and effortlessly performed with little resistance, making it easy to use.

Furthermore, during the fixing or unfixing operations, the membrane material can be used without excessively rubbing it and causing scratches, creases, or cracks, which is extremely beneficial in maintaining the useful life of the membrane material.

Moreover, as a result of the lid section exhibiting appropriate elasticity, the membrane pressing section has the effect of firmly pressing and fixing the membrane material against the groove wall surface on a steady basis, resulting in a strong fixing action.

Further, the elasticity of the lid portion works even more strongly to resist external forces that cause the fitting member to separate from the film material fixing groove, so that high reliability in the fixing operation and effect can be obtained.

Furthermore, since this fixing device has an extremely simple structure consisting of a support frame made as a type of mold material and a fitting member, it can be mass-produced at low cost.

Next, the illustrated embodiment will be described.

First Embodiment In FIGS. 1 and 2, reference numeral 1 denotes a support frame formed as a long member having a membrane material fixing groove 2 and having the same cross-sectional shape perpendicular to the axis.

This support frame 1 is made by cold roll forming of a steel band or the like.

As shown in FIG. 2, the support frame 1 has, in its cross section, a symmetrical inclined wall in which both side walls 1a and Ia are inclined toward the bottom in the depth direction, and each side wall is formed by an arcuate portion having a relatively large radius. A dovetail groove-shaped film material fixing groove 2 is formed in series with the bottom wall.

The upper portions of the side walls 1a, 1a are formed into opening edges 1b, Ib which are curved with a radius large enough to prevent the membrane material 4 from being bent excessively.

Extension portions 1c and lc are formed in the extending direction (horizontal direction) of the membrane material 4 from the opening edges 1b and Ib.

The tip of each extension holder 1c, 1c is a curled part 1d, 1 which is curved downward to prevent the button from damaging the membrane material 4.
It is formed in d.

This is a fitting member formed as a molded material with a uniform cross section.

This fitting member 3 is made by cold roll forming or the like.

In its cross section, the fitting member 3 is a bilaterally symmetrical membrane that is inclined in a substantially . It has presser parts 3a, 3a.

The lower ends of the left and right membrane holding parts 3a, 3a are formed into curled parts 3d, 3d which are curved inward at a radius large enough not to damage the membrane material 4, and are spaced apart from each other.

The upper parts of the membrane holding parts 3a, 3a are formed into arcuate parts 3e, 3e, which are concentric with the opening edges 1b, 1b of the membrane material fixing groove 2 in the support frame 1 and have a radius approximately equal to the outer radius of the opening edges 1b, 1b. The extension receiver of the support frame 1 is part 1c, I
They are formed as extended suppressing portions 3b, 3b that protrude over c and are in close contact with each other.

The left and right extension suppressing parts 3b, 3b are connected in series by a lid part 3f that has an upwardly convex arc shape in the film material fixing groove 2 and exhibits elastic flexibility (arching deformation). There is.

Therefore, when this fitting member 3 pinches and presses both sides of the lid 3f, the elastic flexure of the lid 3f can narrow the distance between the left and right membrane holding parts 3a, and the membrane material fixing groove 2 Reduces resistance when inserting (or removing)
Furthermore, it is possible to eliminate the risk of damage due to rubbing of the membrane material.

Next, the method of use and operation of the hard film material fixing device having the above structure will be explained.

The support frame 1 is installed in advance by welding, screwing, etc. at key locations on the vinyl wall or other building, with the membrane material fixing groove 2 facing outward from the vinyl wall. is fixed.

The membrane material 4 is spread over the membrane material fixing groove 2 of the support frame 1.

The fitting member 3 has its membrane holding parts 3a facing toward the membrane material fixing groove 2, faces substantially parallel to each other along the support frame 1 from above the hard membrane material 4, and extends from one end to the other end. Gradually pinch both sides of the lid part 3f and bend the lid part 3f in order. While narrowing the gap between the left and right membrane pressing parts 3a, 3a, tighten the membrane pressing parts 3a, 3a together with the membrane material 4. The membrane material 4 is pushed into the membrane material fixing groove 2 by the parts 3d and 3d.

In this way, the membrane material 4 can be inserted without being rubbed too hard.

In addition, the left and right membrane pressing parts 3a, 3a of the fitting member 3 are in a compressed state with a slightly narrowed interval within the membrane material fixing groove 2,
Due to the repulsive force, the film pressers 3a, 3a press the film material 4 against the both side walls 1a, 1a of the film material fixing groove 2, achieving the purpose of fixing.

Conversely, when it is necessary to release the fixation of the membrane material 4, the fitting member 3 is moved from one end to the other end of the lid part 3.
It is possible to remove the membrane material 4 without strongly rubbing it while holding both sides of f and narrowing the distance between the left and right membrane holding parts 3a, 3a.

Next, FIG. 3 shows a second embodiment of this invention.
