Description

[Detailed Description of the Invention] The present invention relates to a cross member of a tire chain, that is, a cross member that crosses the ground contact surface of a tire in a tire chain.

As shown in FIG. 1, some cross members of tire chains are made up of a wire cable and a number of sleeves S attached to the wire cable W.

Since this cross member uses wire cable as the aggregate, it has the advantage of being easy to attach to a tire and generating less noise.

However, this cross member had a drawback in that the sleeves S were lined up in a row and the surface was smooth and came into contact with the road surface, so the engagement force with the road surface was weak.

This proposal aims to increase the engagement force with the road surface without sacrificing the advantages of using wire cables as the aggregate, and uses a spherical body (steel ball) instead of the sleeve S as the road surface engagement member. Features. The present invention will be explained below with reference to embodiment figures.

In FIG. 2, reference numerals 1 and 1 denote a pair of side ring forming members disposed on both sides of the tire, which are preferably made of wire cables, but may also be made of chains, ropes, etc. Reference numerals 2 and 2 are fasteners that connect both ends of the members 1 and 1 to each other. Note that these are made up of publicly known products.

3 is the cross member according to the present invention. That is, the cross member 3 consists of a wire cable 4 and a number of (steel) spherical bodies 5 attached to the wire cable 4.

To make this cross member 3, for example, it is sufficient to make a hole 6 in the steel ball 5 and insert the wire cable 4 into the hole 6. In this way, the required number of steel balls 5 can be attached to the wire cable 4. This becomes a cross member 3.
A suitable spacer (not shown) may be provided between the steel balls 5, 5. The steel ball 5 may be loosely coupled to the wire cable 4 or may be fixed.

The cross member 3 thus formed is connected to the side ring forming members 1, 1 by means of a T-shaped connector 7 or the like.

According to the present invention having the above structure, the surface of the cross member becomes an uneven surface due to the steel balls 5, so that the engagement force with the road surface is significantly increased compared to the known product shown in FIG. Moreover, according to the present invention, since the wire cable 4 is used, there are advantages such as less noise and convenient handling.

It goes without saying that the steel ball (spherical body) may be an elliptical ball.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of a conventionally known tire chain cross member, and FIG. 2 is a perspective view of the cross member of the present invention. 1 is a side ring forming member, 2 is a stopper, 3 is a cross member, 4 is a wire cable, 5 is a spherical body, 6 is a hole, and 7 is a T-shaped connector.
