DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail type film fixing device for a film stretching house.

[0002]

2. Description of the Related Art A film-extended house installed as a greenhouse for agriculture or horticulture is composed of a polyester film, a fluorine-based film, and PO (polyolefin) on a frame for a house assembled by connecting a number of pipes and the like. ) It is configured by covering a greenhouse space with a system film or the like. The stretched film needs to be stably fixed on the frame so that it can withstand strong winds, and for this purpose, various film stretching house film fixing devices are used.

[0003] As a film fixing device for a film-extended house, for example, a groove extended toward the inside of a metal holding rail mounted on a frame of the house so that an opening is directed outward is provided in a groove for the house. 2. Description of the Related Art There is known a device for fixing a film by inserting a metal spring bent into a corrugated rod shape with a film interposed therebetween. In this device, the film is fixed by pressing the film against the side surface of the groove of the holding rail using the elasticity of a metal spring.

[0004]

However, in this device, on the side of the groove of the holding rail, the film is locally in contact with the top of the corrugation according to the shape of the spring. There was a problem that the film was easily torn due to rubbing caused by the action of wind. In particular, PO-based films are often used in recent years because they have excellent weather resistance, do not generate harmful gases even when burned, and have the advantage of being easily disposed of.
It has a property that is particularly weak against rubbing. For this reason, it is difficult to use an auxiliary member for holding the film such as mica wire, so if the stretched PO-based film is slightly vibrated by wind or the like, frictional contact with the fixing member or the like near the film fixing portion occurs. It was easy to be damaged.

[0005] Even if the film is not damaged, such a large number of local fixings tend to cause wrinkles on the film surface, and such wrinkles may collect condensation and cause water drops to fall into the house. Drops of water droplets often have an adverse effect on crops that have received the water droplets, and particularly in the cultivation of flowers in a house, if water drops fall in the house, the flowers are likely to rot. Further, when wrinkles are formed, there is a problem that the permeability of the film is reduced.

[0006] In order to reduce the damage of the film due to the rubbing described above, a metal spring coated with a sponge resin or the like is also known. However, since the film is locally fixed, the film may be damaged. And the film was easily wrinkled.

A fixing device for continuously fixing such a film while avoiding such local fixing has been proposed. FIG.
Reference numeral 8 denotes a conventional film fixing device for a film stretching house for continuously fixing. In this fixing device, a metal holding rail 10 attached to a frame of a house is used.
A resin inner rail 102 is fitted into the groove 0 with a film 101 interposed therebetween, and the inner rail 102 is pressed by a wave spring 103 so as to increase its width, thereby fixing the film 101. In this way, the film 101 can be continuously fixed on the surface between the holding rail 100 and the inner rail 102.

In such a device, the inner rail 1
02 alone has a weak force to press the film in the groove,
After the inner rail is fitted into the groove, the inner rail 102 is temporarily fastened using the temporary fastener 104 so as not to come off from the holding rail 100, and then the wave spring 103 is fitted into the inner rail 102.

However, there is a problem that the wave spring 103 is elastically deformed in a direction in which the wave spring 103 contracts due to the tension applied to the film due to the strong wind, and comes off the holding rail 100. For this purpose, it is conceivable to increase the spring force of the wave spring 103. However, it is extremely difficult to push the wave spring 103 into the groove of the holding rail 100, and there is a problem that the work efficiency is further reduced.

The temporary fastener 104 is a wave spring 1
Since it is used only for temporary fixing of the inner rail 102 until 03 is fitted in the inner rail 102, when the wave spring 103 is expanded in the inner rail 102,
Since a gap is formed between the inner rail 102 and the temporary fastener 104 and does not directly restrict the contraction deformation of the wave spring 103, the temporary spring 104 is
03's shrinkage prevention function cannot be fully demonstrated. On the other hand, when the elastic force of the wave spring 103 is increased, there is a problem that it is difficult to compress and contract, and the workability is reduced.

Further, since the inner rail 102 and the wave spring 103 are separated from each other, there is a problem that the fixing work of the film becomes complicated.

Further, the film 10 is held in the holding rail 100.
When fixing a plurality of sheets 1, the upper film is inserted into the inner rail 102 to which the lower film is fixed and is fixed by another wave spring 103. Problems arise.

As another conventional example, as shown in FIG. 39, a pair of left and right rail one-side members 1
02a, 102b, and one rail one-sided member 10
2a and the other rail one-side member 102b
Has been proposed which is slidably fitted in the fitting groove 102d, but has the same problem.

When the film 101 is sunk into the holding rail 100 by the inner rail 102, the film 101 is required to have a stretching ability. However, since the fluorine-based film, which has been widely used in recent years and can withstand many years of use, has poor stretchability, it is not possible to take a large amount of film sinking allowance, so a film holding device that sinks the film into the holding rail is used. However, there is a problem that it is difficult to employ a fluorine-based film.

An object of the present invention is to solve the above-mentioned problems, to provide a film fixing apparatus for a film-extended house which can securely fix a film to a frame of a house and which can be easily operated. It is an object of the present invention to provide a film fixing device for a film extension house which can be fixed without sinking into a film.
