Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a tire chain connector that allows easy connection of the side chain and cross chain of a tire chain, for example, and is designed to prevent the tire chain from breaking during manufacturing or mounting on the tire. The purpose of the present invention is to provide a tire chain connector that can be easily and quickly connected at various times.

[Conventional technology]

A conventional tire chain connector, as described in Japanese Utility Model Publication No. 58-36563, has hooks formed at both ends and a stopper biased upward by a spring in the center of the connector body. Therefore, it is known that a chain can be fitted into the hook portion against the spring elasticity of the stopper, and can similarly be pulled out against the spring elasticity of the stopper.

[Problem that the invention attempts to solve]

However, in the above conventional example, the hook part of the coupling main body easily comes off from the chain due to slight vibrations or shocks, and if the spring elasticity of the stopper is strengthened to solve this problem, it becomes difficult for the chain to fit into the hook part. There was a drawback. Another drawback is that snow tends to accumulate between the hook portion of the connector body and the stopper, making it difficult to attach and detach the chain. Therefore, the tire chain connector of this invention is
The hook part of the coupling body does not come off the chain due to vibration or impact, and the chain can be easily fitted into the hook part. Furthermore, snow does not accumulate between the hook part of the connector body and the stopper, and there is no problem in attaching and detaching the chain.

[Means to solve the problem]

In other words, the present invention has a fixing ring part at one end,
A connector main body that has a hook portion that opens inward at the other end, and a retaining portion that is housed along the length of the connector body and that opens and closes the opening of the hook portion at one end. and a stopper with a temporary fixing part near the retaining part, and a stopper that is slidable on the connector main body, and when it slides beyond the temporary fixing part towards the opening of the hook part, the stopper stops coming off. It is an object of the present invention to provide a tire chain coupling device having a sliding ring which is brought into close contact with the opening and which moves a stopper part of the stopper in the opening direction when the stopper is slid toward the fixing ring part. It was developed for this purpose.

[Examples and their effects]

Next, an embodiment of the tire chain connector of this invention will be described based on the drawings. In FIGS. 1 to 4, reference numeral 1 denotes a connector main body having a ring portion 2 for fixing to a cross chain 11 at one end and a hook portion 3 opening inward at the other end. The fixing ring part 2 is rounded in advance on both sides of the attachment part to the cross chain 11,
Trying to prevent wear and tear. The connector main body 1 is connected in the width direction by a hook portion 3, and is separated into a pair of left and right parts, and is made by cutting a plate-shaped material. A stopper 4 having spring elasticity is housed in the middle of the two parts of the connector main body 1 along its length. The stopper 4 has one end raised upward to form a retaining part 5 that opens and closes the opening of the hook part 3, and the vicinity of the retaining part 5 protrudes upward to form a temporary retaining part. 6 is provided. And it is biased upward in advance by spring elasticity. Reference numeral 7 denotes a sliding ring that can freely slide on the connector main body 1, and is attached to straddle both sides of the connector main body 1, which is separated into two parts. A projection 9 is provided in a hollow portion of the bifurcated portion of the connector main body 1 so as to protrude above the lower horizontal bar 8 of the sliding ring 7. This sliding ring 7 is attached to the hook portion 3
When the stopper 4 slides beyond the temporary fixing part 6 toward the opening 10, the stopper part 5 of the stopper 4 is lowered and brought into close contact with the opening 10. Furthermore, when the stopper 4 slides toward the fixing ring part 2, the end of the stopper 4 on the side of the retaining part 5 is biased upward in advance, so that the retaining part 5 of the stopper 4 is moved in the opening direction. It's summery. Note that the projection 9 of the sliding ring 7 pushes the stopper 4 upward, so that the stopper 4
The operation of moving the retaining part 5 in the opening direction is performed reliably. From the viewpoint of rust prevention, it is desirable to use stainless steel for each part in the above embodiments, but it goes without saying that other materials can also be used as long as they have a rust prevention effect. Also, within the scope of the technical idea of this invention,
It can be used for various purposes. By the way, you can install the tire chain connectors of this invention on both sides of the cross chain so that it can be easily connected to the side chain, or you can prepare only the tire chain connectors of this invention and use it when the tire chain breaks. It is possible to easily connect them. It can also be used to connect side chains and for other purposes.

[Effect of the idea]

Since this invention is constructed as described above, it is possible to easily and quickly connect the tire chain when the tire chain is broken during manufacture or when the tire chain is attached to a tire. Moreover, the opening of the hook can be opened and closed reliably, and the opening and closing operations are also very easy.
