Description

Snow Chain Fastening Snow Chain {SNOW CHAIN JOINED AT WHEEL SIDE}

The present invention relates to a snow chain that is fastened to an automobile wheel, and in order to facilitate the attachment and detachment of a snow chain to an automobile tire, the device is invented so that the attachment point of the chain can be attached to and detached from the wheel part instead of the edge around the tire.

Conventional tire chains are wound around the tire to fasten the connecting rings at both ends in and out of the body, and elastic rubber or plastic material to prevent them from falling off during operation. It was difficult to wear snow chains because it was pulled into a crisscross or X-shape or O-shape and required a lot of time and effort to wear.

In addition, conventional snow chains have fasteners employing rocker levers at both ends of a snow chain that winds around the tire (Application No. 95-26276 (1995.09.27.), Publication No. 97-12479 (1997.04). .25.), But it was difficult to secure it completely without the side binding using the rubber member.

In addition, the snow chain is made of wire or wire loops, or a string or band of metal embedded in a plastic material, which prevents the sliding of the car left and right, and breaks or breaks easily when the car is running. Short lifespan was a waste factor.

In order to facilitate the attachment and detachment of snow chains and to use the chains semi-permanently, the chains can be worn under any environment other than flat when the vehicle is stationary, rather than by wrapping tires when the snow chains are worn. It is necessary to combine the snow chain with the tire part and the wheel part, and the chain can be used semi-permanently by adopting the steel plate having a constant area and tire curvature, rather than connecting it with wire or chain which is only disposable. Need.

In wearing the snow chain, it relies on the conventional tire part only to avoid wearing it around the tire so that it can be attached and detached by using a solid wheel part that played no role when the conventional chain was worn. The idea is to invent a snow chain that can be used firmly and semi-permanently by arranging the centrifugal force due to the tire rotation to the tire and wheel parts.
