BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire chain attached to a tire of an automobile or the like to prevent slipping.

[0002]

2. Description of the Related Art A conventional tire chain is connected by a conventional type A in which hooks or engaging rings are provided at both ends of both side chains, and the ends of the side chains are connected to each other. There are a side chain, in particular, a conventional type B in which the middle of the outer side chain is cut and the connecting portion is increased, and a conventional type C in which the inner side chain is replaced with a chain other than a chain such as a cable.

[0003]

[Problems to be Solved by the Invention] A conventional type A tire chain is mounted on a tire by placing the tire on a cross chain extending between the side chains and connecting the side chains. Since it is pressed against the tire and does not loosen, it is difficult to connect the inner side chain with no extra part.

On the other hand, in the conventional type B and C tire chains, since the middle of the outer tire chain is cut, it is possible to allow the connecting portion of the inner side chain to be pulled out to the outside of the tire and to make it tense. There is no, and the connection work can be done while visually observing on the outside of the tire, making connection much easier than the conventional type.

However, in connection with the cutting portions in the conventional type B and C tire chains, one end is lengthened and the other end of the chain is inserted into the engaging ring of the other cutting end. The end is locked to the ring element at the appropriate position of the side chain row. At this time, a tensioning tool such as a spring is attached to the extra chain portion while pulling, but this is done by pulling only one of the intermediate cut ends, so the mounting balance between the mounted chain and the tire is poor, and the chain This may cause inconvenience, such as having to reconnect after traveling for a while.

[0006]

Therefore, in the present invention, the conventional type B or C is improved, and an auxiliary chain is provided at an intermediate cutting portion so that both cutting ends are pulled and connected, and the chain is attached to a tire. At the same time, it is possible to achieve good balance, and also to be able to balance naturally after running, and also tolerate a large range of error between the tire volume and the chain volume.

Therefore, ring elements are connected to the cut ends in both directions of the intermediate cut portion of the outer side chain, and a separately prepared auxiliary chain is inserted into both rings, and then the auxiliary chains are pulled so as to cross each other, and The hook tool attached to the end of the auxiliary chain is locked at an appropriate position on the outer side chain.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the drawings.

In FIG. 1, only the outer side chain is shown.

The lower connecting portion A is a known connecting portion at the end of the side chain, and the upper connecting portion B is the connecting structure according to the present invention. The side chain 1 is cut in the middle, and ring-shaped ring elements 2a, 2b are connected to the cut ends 1a, 1b of the cut portion in both directions, respectively, and one continuous auxiliary member is provided inside the ring elements 2a, 2b. The chain 3 is inserted, and the tips 3a, 3 of the auxiliary chain are
b is crossed and pulled in the directions of the respective arrows, and the hook members 4a and 4b attached to the ends thereof maintain the tension state of the auxiliary chain 3 on the ring element at an appropriate position of the side chain row 1. It is locked.

It should be noted that it is advantageous that the hook member is made of an elastic material or that an elastic tensioning device or the like is connected thereto so that the tension can be further increased.

[0012]

According to the present invention, the device of the tire chain is not only facilitated, but the auxiliary chain 3 is locked by pulling the cut ends 1a, 1b in both directions at the intermediate cut portion of the side chain. Therefore, the chain can be attached to the tire in a much better balance than the conventional example in which only one cut end is pulled. Further, even if the balance at the time of wearing is insufficient, the balance naturally improves after running. Further, by adopting the auxiliary chain 3, it is possible to allow a large range of error between the tire volume and the chain volume caused by a difference in tire size, a difference in air pressure, a difference in tire sectional shape, or the like. Therefore, various types of tires and different sizes can be accommodated.
