JPS591493Y2 - Frame of tunnel-type film house - Google Patents

Description

[Detailed description of the invention] This invention relates to a frame that becomes the frame of a tunnel-type film house for agriculture and horticulture.When a synthetic resin film is stretched over the frame, the film has good fixation to the frame. To obtain a film house that can be assembled into a film house in which the film can be easily turned over from the side of the house when ventilating or caring for cultivated plants.

An embodiment of the present invention will be described in detail below with reference to the drawings.

In Fig. 1, numeral 1 is a U-shaped cross section having an outward edge 1a shaped like the hand of a key, and is bent into an arch shape with the open side facing upward; One end of the presser frame is pivotally attached 3 to one end of the shape material 1 by a presser frame that can be inserted and removed from above.

The presser frame 2 is highly elastic and is pre-curved into an arch shape with a smaller degree of curvature than the shape material 1, but it may be straight as long as it is bendable.

Reference numeral 4 denotes a stopper made by bending a single narrow tape-like metal wire as shown in FIG. It enters from 1a and then curves diagonally outward in an arc shape, and its end is once lowered and bent to the key's hand to form an upward leg end 4C54C.

Reference numeral 5 denotes a retaining portion for removing the land where the end of the shape material 1 is bent back, and 6 is a retaining hole portion for a support wire protruding from the lower surface of the shape material 1.

As shown in FIG. 5, the above-mentioned frame frames are arranged coaxially and parallel to the ground, and both ends are inserted into the ground, and the stopper holes 6 are connected to each other with wires 8, and between the form material 1 and the presser frame 2. Synthetic resin film 7
Insert the same film 7 into the mold material 1 by fitting the presser frame 2 into the frame 1 and fix it by pushing it.
The tunnel-shaped film house is completed by pressing and fixing the film while it is still fitted into the mold material 1, and closing the tunnel end.

In this case, as shown in FIG. 4, the leg end 4C of the stopper 4 enters inside the outward edge 1a of the profile 1, and the constriction 4b expanded against the elasticity rotates below the outward edge 1a. The Ω-shaped portion 4a returns to its original shape, is locked to the outward edge 1a, and descends.
The back of the free end 2a of the presser frame 2 is pressed.

When removing a part of the film for ventilation or cultivation care, as shown in Figure 6, flip the Ω-shaped part 4a of the stopper 4 upwards and remove it from the outward edge 1a to the constricted part 4b. When the lock is released, the protruding end 2 of the presser frame 2 reaches the raised Ω-shaped portion 4a.
a floats up and can push up the edge 7a of the film 7.

Therefore, ventilation and cultivation care can be carried out through the gap between the film edge 7a and the ground.

The present invention is as described above, and when the fixation of the stopper 4 for fixing the free end 2a of the presser frame 2 to the end of the profile 1 is released, the free end 2a of the presser frame 2 floats and the head of the stopper 4 is released. The film stops in the section 4a and remains lightly pressed by the presser frame, so when the lower edge of the film is pushed up, the lower edge of the film remains sandwiched between the mold material 1 and the presser frame 2. The width of the opening is kept constant, and when the film is returned to its original position and the head 4a of the stopper 4 is pressed, the head 4a
Since the free end 2a of the presser frame 2 is below, immediately attach the stopper 4.
The presser frame 2 can be fixed to the mold material 1 by holding the presser frame 2.

Claims (1)

[Scope of utility model registration request] One end of a presser frame that can be fitted from above into this arch-shaped profile is pivoted to one end of a profile that is bent into an arch shape with the open side facing upward and has a U-shaped cross section, and has an outward edge. The free end of the presser frame fitted into the same shape can be freely fixed and released from the arch-shaped material with a stopper at the other end of the shape.The stopper is made of metal wire and is curved line-symmetrically, and its head is Ω. shape, the constriction is inserted from the outward edge of the arch-shaped member, the part following the constriction extends outward from the outward edge, and the leg end following this is bent inward, A stop whose leg end is inserted inside under the outward edge of the shape material, and the constricted part is locked under the outward edge of the shape material, making it possible to press the back of the free end of the presser frame with the Ω-shaped part. A frame for a tunnel house type film house with metal fittings.
