Embodiments of the present invention will now be described in detail with reference to the drawings. A connecting tool 10 shown in FIGS. 1 and 2 has a shaft rod 12 made of wire or the like, and a welding process to the shaft rod 12. And rings 11a and 11b for holding the filaments of the nets to be connected, which are fixed by the above means. These rings 11a and 11b are provided at different positions in the circumferential direction of the shaft rod 12, respectively. The rods 12 are arranged in two rows at desired intervals in the length direction. In the illustrated embodiment, rows of rings 11a, 11a, ... And rings 11b, 11b ,.
・ 2 at the position where the
There are rows.

Each of the rings 11a and 11b in each row is formed with an opening 13 into which a line can be elastically pushed. The opening 13 has rings 11a and 11b.
Is cut into a part of the wire constituting the, and both sides of the cut are bent toward the inner side of the ring, and at least a part of the space between the bent parts 13a, 13a is to be pressed from a linear diameter Although the opening 13 is narrowed, the shape of the opening 13 is arbitrary and may be any as long as the filament can be elastically pushed in. For example, as shown in FIG. , 13a may cross each other. Alternatively, the both sides of the cut may not be bent toward the inside of the ring.

The number of rings 11a and rings 11b in each ring row is not limited to three as shown in the figure, but may be two or four or more, and the number of rings is different between rows. Is also good. Further, the arrangement interval of the rings in each row is also arbitrary, and for example, when three or more rings are provided, they may be arranged at equal intervals or different intervals, as shown in FIG. As described above, the attachment positions of the ring 11 a and the ring 11 b may be different from each other in the longitudinal direction of the shaft rod 12. Furthermore, ring 11
The shapes of a and 11b can be arbitrary shapes such as a circle, an ellipse, a square, and a heart.

When connecting the nets using the connecting tool 10 having the above structure, as shown in FIG. 5, the connecting tools are applied to the abutting portions of the nets 15a and 15b to be connected, and the ends of both nets are connected. Part lines 16a, 16b for each ring 1
The openings 1 are strongly pushed into the openings 1a and 11b. At this time, the opening 13 is elastically expanded by the filaments 16a and 16b, and after passing through the filaments, the narrow width state is restored again.
It does not come out from the rings 11a and 11b through the wire 3, and the connected state of the net is reliably maintained.

Further, the connecting tool 10 attached to the nets 15a and 15b is a linear strip 16 of the rings 11a and 11b.
a line 17 whose movement along a and 16b intersects the line
Since it is regulated by a and 17b, it is unlikely to be gradually dropped from the net by rotating little by vibration due to vibration or the like unlike the conventional spiral connecting tool.

When the sides of the net to be connected are long, a plurality of connecting tools may be used together, or a long connecting tool suitable for the side may be used to connect them. When used in combination, workability is good because the connector can be attached from any position.

When the net to be connected is a diamond-shaped wire net, the above-mentioned connecting tool is directly attached to the row lines of both wire nets, or the frame line inserted into the ring or mesh of the end of the line wire or the bone line for connection. The diamond-shaped wire nets can be connected in exactly the same manner as in FIG.

FIG. 6 shows a case where the ends of three nets 15a, 15b, 15c are connected in a T-shape by using the above-mentioned connecting tool 10. Similarly, FIG. 7 shows two nets 15a, 15b, 15c.
The case where a and 15b are connected in a T-shape by abutting the end portion of the other net 15b at the intermediate position of the one net 15a is shown.

When connecting nets having different wire diameters, or when connecting nets and a wire having a large diameter such as a wire rope, the openings 1 in the rings 11a and 11b.
If you use a connector with different sizes 3,3,
Connection work is easy.

In the above embodiment, two rows of rings 11 are used.
Although the openings 13 are provided in a and 11b respectively, as in the coupling tool 21 shown in FIG.
The opening 23 may be provided only in a and the ring 21b in the other row may be a closed ring having no opening.

When connecting a net made of, for example, a rhombic wire net with such a connecting tool, as shown in FIG. 9, a closed ring 21b is inserted into the net of one net 25a to connect these nets and the ring. 21b for connecting bone line 26
The other ring 21a having an opening 23 while connecting the ring 21b to the net 25a by inserting
The frame line 27 attached to the end of the other net 25b is pushed into the inside through the opening 23. In this case, in order to prevent the connecting bone line 26 from falling off, it is desirable that the end portion of the bone line 26 be subjected to pullout prevention processing such as bending.

In the coupling tools 10 and 20 of the above-mentioned respective embodiments, the rings are provided in two rows at different positions around the shaft rod.
It is also possible to provide more than one row.

FIG. 10 shows a further different embodiment of the connecting tool. In this connecting tool 30, two rings 31a and 31b are integrally formed by bending one line into a substantially figure-eight shape. However, the opening 33 is provided in one of the rings 31 a, and the shaft rod 32 is attached at a position that does not prevent elastic deformation when the line is pushed through the opening 33. According to the fixture 30 of this embodiment, since the opening 33 of the ring 31a can be elastically spread easily during the connecting work, the connecting work is simplified.

[0021]

According to the connector of the present invention having the above structure, these nets can be connected simply by pushing the wire of the net to be connected into the ring through the opening.
The connecting work is very simple because it does not need to be rotated about the axis many times unlike the conventional spiral connecting device. Moreover, unlike the conventional spiral connecting tool, the connecting tool does not rotate little by little due to vibration or the like and gradually falls off from the filament, so that the connected state can be reliably maintained.
