Description

Snow chain {snow chain}

The present invention relates to a snow chain, and more particularly, to a snow chain which can easily attach and detach a snow chain to a tire, increase the gripping force with the floor and enable stable running even when the weight of the vehicle is light or snowy. The present invention also relates to a snow chain which can increase the gripping force between a tire and a snow chain, thereby preventing a snow chain from moving during driving, thereby enabling stable running.

In general, when snow is piled up on the road or the road surface freezes, there is a possibility that the car slips during driving, which may lead to various accidents. In particular, when the driver climbs the hill from a stopped state or presses the brake At the moment, the car turns regardless of the will of the driver, so that it becomes more and more likely to encounter other cars or obstacles nearby.

In this way, snow chains are mounted on the wheels of automobiles in order to prevent slipping when driving on snowy or icy roads. Conventional snow chains have relatively slippery performance when snow accumulates, but it is difficult to mount them on wheels There was a problem.

In other words, since the ladder-type snow chain, which is the most used among the conventional snow chains, must be extended in front of the automobile wheel and then the vehicle must be slightly advanced to fasten the both ends, so that the mounting work and disassembling work are very troublesome, There is a problem that it is difficult to mount and disassemble the chain because the chain must be fastened between the fixing band and the elastic binding band on the inside and the outside of the wheel.

In order to solve such a problem, a technique disclosed in Korean Registered Utility Model No. 20-0474874 as shown in FIGS. 1 and 2 has been proposed. The technical feature is that a plurality of spikes 11 pass through the upper and lower surfaces A contact pad 10 made of a synthetic resin material having a concave groove corresponding to the curvature of the tire 5 formed in the tightly fitting portion 12 so as to be able to be brought into close contact with the tire 5 around the vehicle; And the contact pads 10 are provided on both sides of the contact pads 10 and fixed to each other through the openings 4 formed in the wheel 1 of the vehicle after the contact pads 10 are brought into close contact with the peripheral portion of the tire 5, And first and second fixing strips (21, 22) capable of fixing the pad (10) so as not to move, wherein the contact pad (10) is in close contact with a peripheral portion of the tire (5) And the extension portion 13 extending upward from both sides of the tightening portion 12. The extension portion 13 and the first and second The fixing strips 21 and 22 are arranged to be inclined inward so as to narrow the gap toward the upper side and are formed on the upper surfaces of the tight fitting portion 12 and the extending portion 13 in the longitudinal direction of the tightening pad 10, The protrusion 25 is protruded and the protrusion 25 is formed in a shape of a right triangle having one side and the upper side of the close part 12 and the extended part 13 at right angles It characterized in that the formation is formed forms the left-right symmetrical with respect to the contact pad 10.

However, the technology disclosed in Korean Utility Model No. 20-0474874 has an advantage that it can be easily attached to and detached from a tire. However, by forming only the spark 11 at the center of the contact pad 10, Can not be increased more than a predetermined level, so that the vehicle can not stably travel in the eye of a relatively lightweight vehicle.

Further, since the above-described technique is larger than the size of the opening 4 formed on the wheel and the width of the first and second fixing strips 21 and 22, the snow chain flows back and forth along the surface of the tire There is a problem that the slip prevention function can not be stably performed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a tire having a body which is provided on a surface of a tire and contacts with a floor, And a pair of front and rear bar-shaped anti-skid protrusions are formed along the longitudinal direction of the body so as to be in contact with the bottom surface of the body, By providing a spike, a snowing chain can be provided that can stably travel on snow, even if the vehicle is snowing or has a relatively light weight, by forming a grounding force primarily by the non-slip projecting portion and forming a secondary force through the spike .

It is a further object of the present invention to provide a chain extending from a body, first and second extensions and spikes along a surface of a tire at regular intervals, wherein a hook is formed at an end of the first extension, Each of the chain portions provided on the tire is pulled by the elastic ring and the hooks to the center of the wheel so that the adhesion between the tire and the chain portion is increased to prevent the chain portion from moving back and forth during traveling Thereby enabling a stable running on the snowy road.
