Description

[Detailed description of the invention] The present invention is a cross fastener that can be used when assembling the frame or shelf frame of an agricultural greenhouse, and in particular, it is designed to fasten two pipes that cross each other using a wedge. Regarding the improvement of the cross fastener, the present invention aims to make it possible to securely fasten two pipe materials at an angle within a certain range even if the two pipe materials are not perpendicular to each other.

The following description will be given based on illustrative drawings. FIGS. 1 to 4 show the basic structure of a cross fastener improved by the present invention, where 1 is a main body and 2 is a wedge.

The main body 1 is an inverted U-shaped body consisting of an arcuate portion 4 that fits around a pipe material 3 and both leg plates 5 and 6.
, 6 are bent inwardly and upwardly into wedge retaining parts 7, 8.
Furthermore, both leg plate parts 5 and 6 are provided with cutout recesses 9 and 10 that are open at the lower ends thereof.

One of the leg plate parts 5 and 6 is separated from the arc-shaped part 4, and the free side of the arc-shaped part 4 is bent outward and upward to form a groove-shaped guide 11, and the leg plate part 5 is separated from the arc-shaped part 4. The upper side of the portion 5 is bent inward and downward to form a fitting portion 12 that fits into the groove-shaped guide 11.

Further, at the center position in the length direction of the upper side 12, a narrow width portion 1 is provided.
A retaining piece 14 is connected downward through the groove-shaped guide 11, and a snot 15 in which the engaging piece 14 and the narrow width part 13 are fitted is provided along the length at the bottom of the groove-shaped guide 11. There is.

The wedge 2 has side plate portions 16 on both sides along its length that fit into the lower end wedge retaining portions 7 and 8 of the leg plate portions 5 and 6.
．． It has 17.

To explain how to use it, as shown in FIGS. 1 to 3, the arcuate portion 4 of the main body 1 is fitted onto the pipe material 3, and the pipe material 18 is brought into cross contact with the pipe material 3 at a predetermined angle. The notch recesses 9 and 10 of both leg plate portions 5 and 6 are fitted into each other with both leg plate portions 5 and 6 relatively moved along groove-shaped guides 11.

After that, the wedge 2 is driven in parallel to the pipe material 3 with its side plate parts 16 and 17 fitted into the wedge retaining parts 7 and 8, so that the wedge 2 and the main body arc-shaped part 4 are connected. Both pipe materials 3 and 18 are pressed and fastened together between them.

In the present invention, as described above, in the loss fastener, both leg plate parts 5
. A feature is that the abutting portions of the fitting portions 12) are formed in an uneven shape in the direction of relative movement so that they fit into each other at arbitrary relative positions.

Specifically, as shown in FIG.
The lower edge 20 of 2 can be formed into an uneven edge that fits into the uneven bottom surface 19.

According to the cross fastener of the present invention that can be implemented in this way,
Within the allowable range, two pipe materials can be fastened to each other in an intersecting state at any relative angle. The abutting parts of the two parts that come into contact with each other at the joint are formed in an uneven shape in the direction of relative movement so that they can fit into each other at any relative position, so that the angle of the pipe material will not fluctuate during wedge driving work. There is no need to worry about the pipes falling apart, and both pipe materials can be reliably held at the set relative angle at all times, allowing for a strong connection.

In addition, as shown in FIG. 6, by slightly twisting the retaining piece 14 that protrudes downward from the sulin I-15 around the small middle part 13, or by bending it laterally, the leg plate part 5 It is also possible to prevent this from separating from the arcuate portion 4.

Furthermore, as shown in FIG. 7, if both the leg plates 5 and 6 are configured to be slidable relative to the arcuate portion 4, the permissible range of relative movement between the leg plates 5 and 6 is expanded. Even if the inclination of the pipe material 18 with respect to the pipe material 3 is large, both can be reliably fastened.
