Description

Snow chain

The present invention relates to a snow chain, and more particularly, to a snow chain capable of facilitating the installation of a snow chain by allowing a plurality of snow chains to be installed on a tire.

In general, a snow chain is used by being mounted on a tire of a car in winter, and prevents the car from slipping with the ground when the car is driving on a snowy or icy road so that the car can run smoothly.

The snow chain as described above includes a non-skid device that surrounds the tire and maintains frictional force with the road surface, and an inner strap and an outer strap that binds the non-slip device in close contact with the tire, so that the inner strap can be caught and bound. It is composed of a fastening binding means consisting of a locking ring provided on one end of the inner strap and a locking hole provided on the other end of the inner strap, and a tightening means for fastening and binding the outer strap.

Here, the non-slip device is mainly used in a chain type made of a chain and a pad type made of rubber or urethane.

Since these snow chains are made in various sizes such as 15 inches, 16 inches, 17 inches, 18 inches, and 19 inches, the size of the tire, that is, the diameter of the tire, it is difficult to separately manufacture a snow chain according to the size of each tire. have.

In addition, as the size of the tire is different, the spacing of the slipper of the snow chain is different from each other.

In addition, as each snow chain is produced, the manufacturing cost of the snow chain increases, and there is a problem in that the automation for the production of snow chains of different sizes is very poor.

For example, 'snow chain' is disclosed in Patent Document 1 below.

The snow chain according to the following Patent Document 1 includes an anti-skid device that surrounds a tire to maintain friction with the road surface, and an inner and outer strap that binds the non-skid member to closely adhere to the tire and the inner strap and binds the inner strap. In the snow chain comprising a locking ring provided at one end of the inner strap and a hook provided at the other end of the snow chain, and a fastening means for fastening and binding the outer strap, the fastening and binding means comprises: It is provided on one side of the outer strap so as to engage and bind the outer strap in the tightening direction, a latch belt having a latch projection on one side, and the other side of the outer strap corresponding to the latch belt, the latch of the latch belt Maintaining elastic pulling force so that the latch belt is pulled in the tightening and binding direction so that the latch belt has a latch engaging piece that locks the protrusion in the tightening direction, and the inner and outer straps do not loosen as the non-slip device is stretched during vehicle operation. It is composed of a tie-pulling ball.

17 shows a fixing clip 121 installed on the binding straps 111 and 211 and the locking ring 151, wherein the fixing clip 121 includes a first connecting member 130 and a second variable connecting member ( 150) is installed in the overlapping area.

That is, at the connection portion of the first snow chain 101 and the second snow chain 102 , the binding strap 111 of the locking ring 151 and the binding strap 111 of the first connection member 130 are vertically arranged. The overlapping is fixed by inserting the two binding strings 111 overlapping each other into one fixing clip 121, respectively.

Accordingly, by stably fixing the binding strap 111 , it is possible to prevent noise generation due to the movement of the binding strap 111 protruding outward according to the rotation of the tire 10 .

<Fifth embodiment>

19 is a three-dimensional view showing a snow chain according to a fifth embodiment of the present invention.

19 shows a snow chain 100 according to a fifth embodiment of the present invention, since the inner binding member 110, the outer binding member 210 and the snow pad member 310 are the same as in the above-described embodiment. , will be described using the same reference numerals for the same names, and overlapping descriptions will be omitted.

19, the first connecting member 130 of the snow chain 100 according to the fifth embodiment of the present invention is provided with a locking hole 140 into which the binding string 111 can be inserted.

By inserting the binding string 111 of the second variable connection member 150 into the locking hole 140 , it is possible to organize the binding string 111 .

In addition, a fixing protrusion 240 protruding to one side is formed on the locking body 238 of the first binding member 230 , and the fixing protrusion 240 has a toothed portion 254 of the second binding member 250 . Corresponding fixing grooves 255 are formed at regular intervals.

The fixing protrusion 240 is seated in the fixing groove 255 of the second binding member 250 to more firmly bind the snow chain 100 .

Although the invention made by the present inventors has been described in detail according to the above embodiments, the present invention is not limited to the above embodiments and various modifications can be made without departing from the gist of the present invention.
