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 metal fitting for installing a covering film devised in view of the inconvenience of fixing the film while being pulled at the edges.

In general, if the above-mentioned covering film is not taut, it will flap in the wind and cause undesirable phenomena such as noise generation and adverse effects on the film itself, but especially when it is a strong film such as biaxially stretched agricultural film. Coupled with the fact that stretching by hand has become difficult, the appearance of metal fittings that allow for simple and reliable tensioning has become increasingly important.

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 ... is attached with a transparent covering film 3, one edge side of the covering film 3 is fixed with a film gripping fitting 4 attached to the vertical pipe 1.1... One side shows a state in which it is fixed using the metal fitting of the present invention indicated by reference numeral 5.

Figure 2 is an enlarged view of the main parts, and Figures 3 to 6 of the casing.
The figures show several embodiments of the metal fittings of the present invention.

In the example shown in FIGS. 3 to 5, a mounting hole 7 for a stopper 9 is formed on the opposite surface of the U-shaped fixing plate 6 that is applied to the side surface of the vertical pipe 1.
7 is drilled.

As the stopper 9, a bolt nut, a split pin, a cotter, or the like can be used.

These fasteners 9 allow the U-shaped fixing plate 6 to be securely fixed to the vertical pipe 1.

In the example shown in FIG. 6, the U
Although it has a shape fixing plate 6, it does not have holes corresponding to the mounting holes 7.7 for the fasteners 9.

Instead, the opposing surface of the U-shaped fixing plate 60 is formed with inwardly bent portions 17, 17 as engagement legs of the stop 9.

The stop 9 in this example is a portion 9 that presses against the side surface of the vertical pipe 1. and leg portion 9b*91. , and by driving this stopper 9 between the vertical pipe 1 and the bent portion 17.17, the U-shaped fixing plate 6 can be firmly fixed to the vertical pipe 1.

In either case, the mounting hole 8 for the screw member 10 is formed by further bending one side of the U-shaped fixing plate 6 outward, and the head of the screw member 10 inserted from below the mounting hole 8 is formed. 11
(See Figure 3) Or the nut 1 screwed onto the screw member 10
2 (see FIGS. 4 and 5) comes into contact with the lower surface of the mounting hole 8 to prevent it from coming off upward.

There are two ways to insert the screw member 10 as described above, but when the head 11 is located below, the upper nut 12 is inserted.
(see Fig. 3), and the bitten nut 1
2 is on the lower side, the upper head 11 or the screw member 10 itself with the head 11 removed is fixed to the movable member 13 (
4 and 5), the movable member 13 can be freely pulled and pushed apart.

The movable member 13 has bent tongues 14 and 15 that can be bent as shown by the dashed line by tightening with pliers or the like, so that the film gripping fitting 4 can be easily gripped and fixed.

Although the bent tongue pieces 14 and 15 are not shown, they may be provided in two horizontal stages.

The film gripping fitting 4 may have any structure conventionally used, but in the illustrated example, it has a clamping opening 4 as shown in FIG. Case body 4b having
The film 3 is sandwiched between the holding plate 4e and the holding plate 4e, and screws 4d are driven into the pressing opening 4 from the holding plate 4c side to integrate the film 3 and the holding plate 4e.

If necessary, a spring 16 is loosely fitted into a portion of the screw member 10 that extends long above the mounting hole 8.

How to use: Vertical pipe 1, 1. ...U-shaped fixing plate 6゜6,
The film gripping fittings 4, 4 . . . attached to the movable member 13 After gripping the ends of the film 3 with the screw members 10, 10 . ... by turning the movable member 13,
13. By pulling..., the film 3 is stretched to an appropriate tension.

As described above, since the present invention consists of four parts, the U-shaped fixed plate 6, the stopper 9, the screw member 10, and the movable member 13, the number of parts is small and it can be provided at low cost. The film tensioning operation using this device is simple and easy for anyone to perform, and it is extremely superior in that it is extremely easy to create a structure that can withstand the desired film tension. .
