[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for tightening an anti-slip net for a tire.

[0002]

2. Description of the Related Art As a conventional anti-skid net for tires, there is one as shown in FIG.
Is a strip with a mesh and hooks 26, 26 on both sides.
The non-stretchable inner connecting rope 21 is attached and fixed to the inner hooking portion 26 of the net body b provided with ′ through the fittings 22, and both ends of the connecting rope 21 can be connected to each other. On the outside, along with the mounting metal fittings 22 'attached to the respective outer locking portions 26', the tightening rubber band 23 (Fig.
(See 15) can be hooked.

When the non-slip net B is attached to a tire, the net B is attached to the tire C as shown in FIGS. 14 and 15.
The connecting band portion 24 wound around the outer periphery and formed at one end of the net body b is inserted into the connecting portions 25, 25 formed at the other end to connect both ends of the net body b and to the inside of the net body b. Connect both ends of the attached connecting rope 21 (Fig. 14), and then hook the ring-shaped tightening rubber band 23 to the mounting metal fittings 22 'attached to the respective hooking portions 26' on the outside of the net body b. (Fig. 1
5) The non-slip net B is pressed against the outer peripheral surface of the tire C.

However, as described above, the inner connecting rope 21
Since it is non-stretchable, it is slightly loosened from the state where it should be completely tightened after the anti-slip net B is attached to the tire C, and the anti-slip net B is completely adhered to the tire C. There is no state.

For this reason, the non-slip net B floats or laterally shifts with respect to the tire C during traveling,
There is a possibility that noise may be generated and the non-slip net B itself may be damaged.

[0006]

[Technical Problem] A technical problem to be solved by the present invention is to firmly adhere a non-slip net to a tire surface so as not to lift or laterally shift.

[0007]

[Technical Means for Solving the Technical Problem] To solve the above-mentioned problems, the technical means taken by the present invention is to attach a non-slip net to a tire and connect the inside of the non-slip net to a non-stretchable inner connection. This is to double-tighten the rope and the elastic inner tightening band, and to tighten the outer side with the elastic outer tightening band.

[0008]

[Function] After winding the net body around the tire and connecting both ends,
When the inner side of the main body is doubly tightened with the connecting rope and the inner tightening band, the inner side of the net body is pulled toward the center of the tire and the inner half adheres strongly to the tire surface. When tightened with the outside tightening band, the outside of the net body is pulled toward the center of the tire and the outside half strongly adheres to the tire surface, and the entire non-slip net strongly adheres to the tire surface by the uniform tensile force.

When a centrifugal force is generated in the net body by the rotation of the tire during traveling, the non-stretchable inner connecting rope is tensioned and the net body tries to spread outward.
The inner tightening band attached to the inner side of the net body suppresses the expansion of the inner side while the outer tightening band attached to the outer side of the net body suppresses the expansion of the outer side and spreads to the outer circumference. Hold the inner and outer edges of the non-slip net firmly against each other.

[0010]

[Effect of the Invention] Since the present invention is configured as described above, the anti-slip net attached to the tire has the inner connecting rope and the inner tightening band so that the inner side of the anti-slip net is doubled toward the center of the tire. The inner half is strongly attracted to the tire surface, and the outer fastening band is also attracted toward the tire center direction so that the outer half is strongly adhered to the tire surface. Therefore, it is possible to pull the entire anti-slip net toward the center of the tire with a uniform force and firmly adhere it to the tire surface, thus preventing the anti-slip net from slipping or rising during running, and It is possible to prevent the trouble to be induced.

The intended purpose can thus be achieved.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.
