Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a cable for fixing an anti-slip tire chain to a tire, which is used when driving on snowy roads.

[Prior art and its problems]

When driving a car on a snowy road, it is very common to install tire chains in order to reduce the frictional resistance between the tires and the road surface and prevent the tires from slipping on the road surface.

A method of attaching such an anti-slip tire chain to an automobile tire is to use a ring-shaped chain with a certain width (in the case of a metal tire chain, it is not ring-shaped;
This is done by covering the tire from the outside along the tread surface.

However, the tire chain described above cannot be manufactured by simply coating the surface of the tire.
The adhesion between the tire and chain is not perfect,
If a tire deforms while driving, a slip phenomenon may occur between the tire chain and the tire, causing the chain to lose its anti-slip function, or in some cases causing the tire chain to separate from the tire. It was hot.

As a method to prevent this kind of danger, conventional methods have been taken to tighten both sides of the tire chain with tightening cables, thereby tightening the entire tire chain in the direction of the tire's center and tightly fixing it to the tire surface. However, conventional tightening cables simply use elastic metal wires formed into an arc shape, or, in the case of rubber tire chains, have a lock called a ``koki'' at the end. The method of tightening with a tightening belt with a stopper was used, so the tightening force was weak, or in the case of the above-mentioned tightening belt, force was required to tighten the belt. However, it had drawbacks such as being difficult for women and others to operate.

[Purpose of invention]

This invention aims to solve the above-mentioned drawbacks, and has an extremely simple structure.
To provide a cable for fixing a tire chain that can be easily attached even when used by a weak person such as a woman.

Another object of the present invention is to provide a cable for fixing a tire chain that does not cause the joint part to come off accidentally after it has been engaged, even though the fitting means for the joint part is simple. This is what we are trying to provide.

[Key points of the idea]

The present invention integrally forms a locking ring consisting of a rectangular annular body with a hollow interior at the tip at both ends of a cable having a desired length, and a part of the locking ring described above. , respectively, are planes V from both sides in the direction that crosses the axis constituting the annular body.
By forming a notch in the shape of a letter, a locking groove is formed only in the area where the apexes of the two chevron portions are close to each other, and the two locking rings formed at both ends of the cable are used for the locking groove described above. The key point of the invention is to form a single loop body by fitting the grooves together to achieve engagement.

〔Example〕

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

Reference numeral 1 denotes a fixing cable body having a desired length, and joint fittings 2, 2 are attached to both ends of the cable body.

The joint fitting 2 has an insertion hole 22 formed at the base end of the fitting body 21 for inserting and locking the end of the cable 1, and the tip of the fitting body 1 has a wall thicker than the fitting body. A thin oval locking ring 23 is integrally formed.

Reference numeral 24 denotes a locking groove formed in a part of the oval locking ring body 23, which is cut out from both sides of the shaft forming the ring body so as to have a V-shape in plane.
The apex portions of the two V-shaped fonts are engraved so as to form an open portion where they touch each other in the center.

3...3 is a hook fitting with a J-shape on the side that is locked to the edge of the tire chain 4 at a predetermined interval, and the base end is fixed to the tire chain 4, and the locking hook part is bent at the tip. The cable main body 1 for fixation is to be locked therein.

[Use of this invention]

When using the present invention, hook fittings 3 attached to the tire chain 4 at predetermined intervals...
Fig. 4 shows an example of the locking grooves 24, 24 formed in the locking rings 23 of the two joint fittings 2, 2, which are engaged with appropriate parts of the fixing cable 1 and then attached to the ends thereof. By fitting and locking it in this way, it becomes one loop body.

After the locking grooves 24, 24 are fitted into each other, the locking ring bodies 23, 23 form one long chain-like body as illustrated in FIG.

By tightening the loop-shaped body formed by engaging this locking ring while fixing it to the tire chain 4, the tire chain 4 is firmly fixed to the tire.

[Effect of idea]

Since the present invention is configured as described above, after the cable main body 1 is locked to the hook fittings 3...3,
It can be attached by an extremely simple operation method of simply integrating the joint fittings 2, 2 attached to both ends with the locking grooves 24, 24, and can be attached using a conventional belt-type fixing string. Alternatively, the handling method can be significantly simplified compared to a fixing loop metal fitting with extensibility.

Moreover, the joint fittings 2, 2 which are engaged and integrated at the locking grooves 24, 24 are in the second position after the engagement.
As illustrated in the figure, it takes on the shape of a single chain, and has the excellent feature that the joint metal part is not bulky.
