Description

Snow chain having eisens

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow chain for automobiles, and more particularly, to a snow chain having an eigen that is configured to be tightly coupled to the surface of an automobile wheel in an eisen manner and that can be easily mounted and removed.

Generally, snow chains are mounted to prevent the car from slipping when it snows or when the road is frozen. Such snow chains have been widely used in various types until now.

Among them, the most frequently used are woven chains made of metal to form a mesh and mounted on the surface of automobile wheels to prevent slippage of the car on snowy roads or ice roads by the frictional force of the chains.

However, since the snow chain formed in the form of such a net has to be manufactured in accordance with the appearance of the automobile tire, not only is it difficult to manufacture and assemble, but also there is a problem in that the manufacturing cost increases. In particular, the existing snow chains also have a problem that safety is such that the ground area which is grounded on the road surface does not generate enough friction force during sudden braking.

In addition, the snow chain formed in the above form has a disadvantage that can be mounted only when the vehicle is moved. And it is not difficult to center the wheels of the car on the snow chain by moving the vehicle with the driver sitting in the car.

Therefore, in recent years, the middle part of the snow chain has been cut and the fasteners are formed on both sides of the cutting part so that the vehicle wheels can be mounted without moving the vehicle. However, such a snow chain also has a fastener inside the wheels. Since it is mounted while holding the wheel, there is a problem that the usability is greatly reduced due to difficulty in mounting and detaching.

The present invention has been made to solve the problems described above, by maximizing the ground area of the wheel by constituting the ground surface in contact with the wheel of the car in the form of an eigen that is integrally in close contact with the ground surface of the wheel rather than the net method The purpose is to prevent slipping as much as possible during braking force.

In addition, there is a further object to provide a snow chain having an eigen that can be more easily mounted and detached to the car wheel to improve functionality and convenience at the same time.
