Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film fixing jig, and more particularly to a film fixing jig suitable for supporting and fixing a plurality of films in a continuous state and from below. .

[Conventional technology]

In some cases, it is necessary to support and fix a plurality of films so as to be continuous with each other and from below. As a specific example, there is a support for a transparent film for lining which is stretched inside the top of a horticultural house formed of a transparent film or plate material made of a vinyl chloride resin or the like to improve the heat insulation of the house.・ Fixation can be mentioned.

As described above, as a method of supporting and fixing the film in a continuous state, and from below, a fixing jig having an adhesive layer formed on a flat lower surface is used to fix the film adjacent to the adhesive layer. It is conceivable to temporarily fix the ends in a state of being close to each other, and then to perform a firm original fixation.

In order to reliably perform the temporary fixing, the area of the film that is in contact with the pressure-sensitive adhesive layer at the time of temporary fixing (adhering area) is set to be substantially equal to each other for the adjacent films, and to be substantially constant for all the films. Is important.

As described above, in order to make the adhering areas of both adjacent films equal to each other, each of the ends of the film is attached to the pressure-sensitive adhesive layer so that each end thereof is located at approximately a half of the width of the pressure-sensitive adhesive layer. It is necessary to stick the ends.

[Problems to be solved by the invention]

However, when sticking the end of the film to the pressure-sensitive adhesive layer, it takes time to adjust the end of each film to approximately one-half the width of the pressure-sensitive adhesive layer as described above, and therefore, the method described above. When the film is stretched by the method, there is a problem that work efficiency is extremely poor.

Accordingly, an object of the present invention is to provide a method for temporarily and securely fixing a plurality of films in a continuous state, and when supporting and fixing the films from below, and when the films are stretched. An object of the present invention is to provide a film fixing jig which can greatly improve the work efficiency of the film.

[Means for solving the problem]

The present invention has a fixed support portion, a pressure-sensitive adhesive layer is formed on the opposite side of the fixed side of the fixed support portion, and the first inclined surface and the second inclined surface on which the surface itself or a tangent line on the surface intersect each other. A main body having an inclined surface, and a pressing and fixing member for pressing and fixing the two films temporarily fixed to the main body by the adhesive layer on the first and second inclined surfaces. The above object has been achieved by providing a film fixing jig.

[Action]

Since the surfaces of the first inclined surface and the second inclined surface themselves or tangents on the surfaces intersect with each other, without paying special attention, a film is formed on the pressure-sensitive adhesive layer formed on each inclined surface. Since the end of each film can be temporarily fixed with a fixed sticking area only by sticking the end of the film, the film can be temporarily fixed securely, and the temporary fixing can be quickly performed. Since it can be performed, the efficiency of the film stretching work can be greatly improved.

Further, the first inclined surface and the second inclined surface are each formed by a concave curved surface, and the back side of each of the first inclined surface and the second inclined surface is formed by a convex curved surface. And the pressing and fixing of the film can be performed more reliably.

〔Example〕

Hereinafter, a film fixing jig of the present invention will be described based on an embodiment shown in the drawings.

FIG. 1 is a cross-sectional view showing an outline of a film fixing jig according to one embodiment of the present invention, together with an outline of its use, and FIG. 2 is a schematic diagram for explaining the operation of the film fixing jig. It is sectional drawing. FIG. 3 and FIG. 4 are schematic cross-sectional views each showing an attached state of the film fixing jig.

The film fixing jig of this embodiment includes a long main body 1 having a cross section as shown in FIG. 1 and a long pressing fixing member which can be fitted to the main body 1 from below. And 2.

The main body 1 has a fixed support portion 3 for mounting on an aggregate or the like (not shown in FIG. 1) located above, and on the opposite side of the fixed side of the fixed support portion 3, any one is provided. It has a first inclined surface 4 and a second inclined surface 5 which are formed as flat surfaces and intersect each other, and an adhesive layer 6 is formed on the first inclined surface 4 and the second inclined surface 5. Have been.

Next, the operation of the film fixing jig will be described with reference to FIG.

First, an end of the first film 7 having a predetermined width is attached to the pressure-sensitive adhesive layer 6 on the first inclined surface 4, and then an end of the second film 8 having the same shape is adhered to the adhesive layer 6 on the second inclined surface. 6, and both films 7 and 8 are temporarily fixed as shown in FIG.

Next, as described above, the first inclined surface 4 and the second inclined surface 5
The two films 7, 8 temporarily fixed by the adhesive layer
The pressing and fixing member 2 is externally fitted to the main body 1 and pressed.
By fixing, the original fixing of the film as shown in FIG. 1 is achieved. In addition, since the pressing and fixing member 2 itself has elasticity, the pressing and fixing member 2 is externally fitted to the main body 1 in the state shown in FIG. This is easily achieved by pressing and lifting the pressing and fixing member 2 with the opening side of 2 facing upward. That is, when the opening side of the pressing and fixing member 2 is pressed, both opening ends 2a are pushed and spread in the left-right direction, and the pressing and fixing member 2 can be fitted simply by pushing up.

In the case where the film is temporarily fixed to the main body 1, as shown in FIG. 2, the film 7 can be stuck to the first inclined surface 4 in a state where the leading end portion 7a is left. 8 with the tip 8a left over,
Can be adhered to. This is because even if the tip 7a occurs, the film 7 is formed of a hard material because the first inclined surface 4 and the second inclined surface 5 intersect with each other at a predetermined angle θ. Even if the tip 7a
Is effectively prevented from sticking to the second inclined surface 5 beyond the first inclined surface 4, and also in the case of the film 8, the leading end 8 a of the film 8 exceeds the second inclined surface 5. This is to prevent sticking to the first inclined surface 4.

As described above, in the above-mentioned film fixing jig, when the film is temporarily fixed to the main body 1, if the above-mentioned tips 7a and 8a are stuck so that they can be more or less,
As a result, it is inevitable that a certain amount of affixed area is secured between the adjacent films, and as a result, the above films 7 and 8 are fixed.
Can be temporarily fixed securely. In addition, at the time of the temporary fixing, since it is not necessary to pay particular attention to the positional relationship between the end of the first film 7 or the end of the second film 8 and the first inclined surface 4 or the second inclined surface 5, Temporary fixing can be performed easily and quickly. Therefore, the work efficiency when the film is stretched is greatly improved.

 Next, the film fixing jig of the present invention will be described in detail.

In the film fixing jig, the method of mounting the main body 1 is not particularly limited. For example, as shown in FIG. 3, a separately prepared mounting member 10 is fixed to an aggregate 9 made of C Chang steel. The fixed support portion 3 of the main body 1 may be supported and fixed to the mounting member 10 and the aggregate 9 itself can be supported and fixed to the fixed support portion 3 as shown in FIG. And the main body 1 may be directly attached to the aggregate 9.

Further, as shown in FIG. 8, the attachment of the main body 1 of the film fixing jig is performed by attaching two attaching members 10 and
It may be performed along the length direction of the aggregate 9 via 10a, or may be performed perpendicular to the length direction of the aggregate 9 as shown in FIG. Further, as shown in FIG. 10, the mounting of the main body 1 may be performed along the length direction of the aggregate 9 through three mounting members 10, 10a and 10b. In addition, as shown in FIG.
May be performed perpendicularly to the length direction. It is needless to say that the aggregate 9 is not limited to C Chang steel.

In the film fixing jig, the material to be formed is not particularly limited, and both the main body 1 and the pressing and fixing member 2 may be formed of a metal such as aluminum or a synthetic resin such as hard polyvinyl chloride. In particular, when it is formed of a synthetic resin, it can be easily formed by an injection molding method. It is desirable that at least one of the main body 1 and the pressing and fixing member 2 has appropriate elasticity.

In addition, the pressure-sensitive adhesive layer 6 can be formed with a commonly used pressure-sensitive adhesive, and as a simple method, a double-sided pressure-sensitive adhesive tape,
It can also be formed by attaching one of the adhesive surfaces to the inclined surface.

In the film fixing jig, the intersection angle θ between the first inclined surface 4 and the second inclined surface 5 in the main body 1 is not particularly limited, but is 80 to 160 °, preferably 90 to 150 °, more preferably 110-140 ゜. Further, the shape of the main body 1 is not limited to those shown in FIGS. 1 and 2, and for example, the first inclined surface 4 and the first inclined surface 4 whose cross-sectional shape is shown in FIG. The two inclined surfaces 5 may not directly intersect with each other and there may be a predetermined interval between the two.

Further, the first inclined surface 4 and the second inclined surface 5 are not necessarily limited to those formed of linear flat surfaces.

For example, as specifically shown in the cross-sectional view of FIG. 6, the first inclined surface 4 and the second inclined surface 5 are each formed by a concave curved surface, and the first inclined surface 4 and the second inclined surface 5 are respectively formed. The back side is formed of a convex curved surface, and the inclined surface forming portions 4a and 5a on which the two inclined surfaces are formed have a predetermined thickness of a substantially V-shape bent downward toward the side end. Can be mentioned. As described above, since the inclined surface forming portions 4a and 5a have a shape that is bent in an arc shape that is upwardly convex, when the main body 1 shown in FIG. The fitting can be performed more easily, and the pressing and fixing of the film can be performed more reliably.

Further, the first inclined surface 4 and the second inclined surface 5 have tangents on the surfaces intersecting with each other, for example, as shown in FIG. You may.

The shape of the pressing and fixing member 2 is also not particularly limited, and may be variously modified as long as the pressing and fixing member 2 has a function of pressing and fixing the film that can be fitted to the main body 1 and that is temporarily fixed. It is.

In addition, it goes without saying that the film fixing jig of the present invention is effective when applied to a film for lining a horticultural house, but the present invention is not limited to this. In addition, as long as it is supported and fixed from below, it can be applied to various applications, and there is no particular limitation on the film to be stretched, and it is made of synthetic resin such as soft polyvinyl chloride or polyethylene which is usually used. It is also effective when applied to fixing elastic films made of rigid polyvinyl chloride, fluororesin, etc.

〔The invention's effect〕

The film fixing jig of the present invention can easily and surely temporarily fix each film when supporting and fixing a plurality of films in a continuous state and from below, and furthermore, the films are stretched. The work efficiency at the time can be greatly improved.

Further, when the first inclined surface and the second inclined surface are each formed by a concave curved surface, and the back side of each of the first inclined surface and the second inclined surface is formed by a convex curved surface, the fitting of the pressing and fixing member is further increased. It can be easily performed, and the film can be pressed and fixed more reliably.
