Description

[Detailed description of the invention] (Industrial application field) When attaching the anti-slip net B for tires as shown in Fig. 4 to the tire C as shown in Fig. 3,
First, the anti-slip net B is wrapped around the tire and both ends of the net B are connected, the inner edge of the net B is tightened with a tightening tool, and then the outer edge of the net B is tightened with a ring-shaped rubber band. It is something.

The above-mentioned tightening tool is provided with connecting parts connected by connecting fittings at both ends of a specified length of tightening rope, and hooks are attached at specified intervals along the entire length of the rope, and the above-mentioned tightening rope is made of a synthetic material such as nylon. It has a so-called two-layer structure, in which the outer periphery of a core material made of fibers is woven with synthetic fibers such as nylon to cover it, or synthetic fibers such as nylon are bundled into strings and coated with rubber.

However, since the above-mentioned tightening rope is manufactured by weaving synthetic fibers, the attachment parts of the connecting fittings and the latching hooks that connect the connecting parts are carried over and rubbed by the vibrations during running. When the fibers on the surface wear out and break, the stitches begin to unravel and the tightening rope itself is often broken.In addition, when the latter rubber-covered rope is used, when the metal fittings are set, the rubber is crushed and the rope is crimped. There was a drawback that it got worse.

(Technical Issue) The reason why the conventional tightening rope described above was easy to break is that once the braided fibers are cut, they naturally unravel and the wound easily grows. Also, the reason why the crimping is loose is because the rubber is an elastic material and force escapes when crimping.

The technical problem of the present invention is to provide a tightening rope that is free from the growth of wounds caused by wear and from loose caulking.

(Means for Solving the Technical Problem) The means taken by the present invention to solve the above-mentioned technical problem is to provide a connecting part at both ends of a predetermined length of a tightening rope, and to provide a connection part at a constant interval over the entire length of the tightening rope. In the tire slip prevention net fastening device, which is made of a tire slip prevention net that is attached by placing a predetermined number of hooks in place, the tightening rope is wrapped around a core material made of high-tensile fibers, and is then attached to a rubber band through a woven fabric made of high-tensile fibers. It is intended to be constructed by thinly covering layers.

(Functions and Effects) Since the present invention has the above-mentioned configuration, it is possible to use a woven fabric made of high-tensile fibers in the middle and cover the surface with a thin rubber layer, so that the high-tensile fibers can be used for a long period of time. The rubber layer prevents the rubber layer from unraveling, and since the rubber layer is thin, the rubber layer will not be crushed and looseness will not occur when crimping with the metal fittings, which is a useful idea.

Since the core material, which is responsible for the tensile force applied to the tightening rope, is covered and protected by the above-mentioned rubber layer forever, it will never be damaged or cut by metal fittings, and the service life of the tightening tool itself will be longer than that of conventional ones. It is extremely long compared to others.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 2 is a perspective view of a cross section of the tightening rope 1 used in the tire anti-slip net tightening device A shown in FIG. The surface of the rubber layer 1C is further coated with a thin rubber layer 1C.

The core material 1a is a bundle of synthetic fibers having high tensile strength such as nylon fibers.
In this case, it is constructed by bundling an appropriate number.

Any fiber may be used for the core material 1a as long as it has high tensile strength, and for example, glass fiber may be used.

In addition, the thin rubber layer 1c around the core material 1a is made of synthetic rubber or natural rubber, and by covering the core material in an uncured state and vulcanizing it, the core material It is strongly bonded and becomes an integral part.

The tightening rope 1 having the above structure is cut into a length according to the tire rim diameter, bent at both ends, and caulked with a fixed tube to form a connecting portion 2, and the connecting portions 2 are connected to each other. They can be connected and detached freely using the metal fittings 2a. In addition, the tightening rope 1
Thirteen to sixteen hooks 3 are attached at regular intervals along the entire length, and the attachment portions of the hooks 3 are caulked and fixed.
