JPS5930679Y2 - Metal fittings for covering film in pipe houses - Google Patents

Description

[Detailed description of the invention] The present invention is for agricultural purposes, such as pipes, etc. When installing a covering film on the outside of the grass skeleton, conventionally the covering film was fixed at one end with the help of many people. This invention relates to a covering film tensioning fitting devised in view of the inconvenience of fixing it while having the edges pulled.

In general, if the above-mentioned covering film is not taut, it will flap in the wind, generate noise, have an adverse effect on the film itself, and cause other undesirable phenomena. Coupled with the fact that it has become difficult to stretch things manually,
The advent of metal fittings that allow for simple and reliable tensioning has been a major concern.

The present invention aims to meet such demands, and its configuration will be explained below with reference to embodiments shown in the drawings.

Figure 1 shows a vertical pipe 1, 1°... bent into an arch shape.
are erected at regular intervals, and straight horizontal pipes 2, 2. . . , to cover the outside of the frame to which the vertical pipes 1, 1 . . . are attached is covered with a transparent covering film 3. . . , and the other side is shown fixed using a metal fitting of the present invention indicated by reference numeral 5.

The perspective view of FIG. 2 shows only the mounting portion of one metal fitting 5 in FIG. 1 in an enlarged manner.

Examples of the metal fittings 5 of the present invention are shown in FIGS. It can be said that a movable member B to which a metal fitting 4 is attached is connected by a screw connector C so as to be able to be pulled and pushed apart.

Details of each part are as follows. The fixing member A has a curved portion 6.7 in the center that covers approximately half of the outer surface of the vertical pipe 1.
The two plate-like bodies 8 and 9 formed with
, 10, and a bold fitting hole portion 11 is formed on at least one side of one plate-like body 8.

The vertical pipes 1 at both ends of the frame in Fig. 1 have bold fitting holes 11 on only one side as shown in Fig. 4, and the middle vertical pipe 1 has bold fitting holes 11 as shown in Figs. 3 and 5. It is best to use them differently, such as those with 11 on both sides.

The movable member B includes a film gripping fitting 4 on a single plate-shaped body 12.
The film gripping fitting 4 can be easily attached by tightening the bent tongues 13, 14 with pliers or the like.

The structure of the film gripping fitting 4 may be any conventionally used structure, but in the illustrated example,
As can be seen from FIG. 2, the case body 4 has a clamping opening 48. The film 3 is sandwiched between the holding plate 4c and the holding plate 4c, and a screw 4d is driven into the pressing opening 48 from the holding plate 4c side to integrate the film 3 with the holding plate 4c.

The upper and lower bent tongue pieces 13 and 14 may be formed in one horizontal step as shown in FIGS. 3 and 4, or in two horizontal steps as shown in FIG. S.

The latter is suitable, for example, when you want to suspend it from another film such as the hem of a cowhide so that it can be turned over.

□The screw connector C includes a bold 15 inserted into the bold fitting hole 11 of the fixing member A, a nut 16 screwed into the bold 15, and a nut 16 that loosely fits into the bold 15 and whose lower end is connected to the bold fitting hole 11. The elastic spring 17 is supported on the upper end surface of the bolt 11, and either the bolt 15 or the bolt 16 is fixed to the movable member B, and at this time, the bolt fitting hole 1 is fixed to the movable member B.
By rotating the head of the nut 16 or the bold 150 that comes into contact with the lower end surface of the movable member B, the movable member B can be freely pulled and pushed apart.

FIG. 3 shows the case where the nut 16 is fixed and the bold rotates 15 times, and when the movable member B is pulled, the portion of the bold 15 that protrudes from the nut 16 becomes longer upward.

FIG. 4 shows a case where the bold 15 is fixed and the nut rotates 116 times, and when the movable member B is pulled, the portion of the bold 15 that protrudes from the nut 16 becomes longer downward.

How to use it is to attach the fixing member A to the vertical pipes 1, 1. ..., attach the film gripping metal fitting 4 to the movable member B, grip the end of the film 3 with the film gripping metal fitting 4, and then turn the screw connector C and pull the movable member B to release the film. 3.

In the present invention, as described above, the fixing member A is a stopper 10.10.
Since it consists of two overlapping plate-shaped bodies 8 and 90 that are joined together, it is easy to form the curved parts 6 and 7 that are suitable for the vertical pipe 1 and the formation of the bold insertion hole part 11, and it is easy to form the curved parts 6 and 7 that fit the vertical pipe 1. Installation is easy and reliable.

In addition, since the movable member B has bent tongue pieces 13 and 14 formed on a single plate-shaped body 12 for fixing the film gripping fitting 4, it is easy to manufacture the bent tongue pieces 13 and 14. The film gripping metal fitting 4 used can be fixed very easily.

Furthermore, a screw connector C connects the fixed member A and the movable member B.
denotes the bold 15 inserted into the bold fitting hole 11 of the fixing member A or the nut 16 screwed into the bold 15.
Since either one of them is fixed to the movable member B, it is possible to create a strong structure that does not take up much space as a mechanism for converting rotational motion into linear motion.

And elastic spring 1 is attached to the bold part 15 between both members A and B.
7 is loosely fitted, it not only prevents the screw from loosening but also provides a buffering effect, which can be expected to prevent excessive force from being applied to the film 3 during strong winds.

Moreover, even if the operator is only one person, the screw connector C
This is extremely effective in that it enables uniform tensioning of the film 3 by tightening the .
