Description

Combined structure of snow chain for automobile

In general, when the road condition is bad due to snow accumulated in winter, the tire sliding (sliding) occurs and the braking force is significantly lowered, so the risk of a large traffic accident is very high. As a matter of fact, most people are prohibited from driving on sloped roads and curved roads.

Therefore, the snow chain is provided as one of means for improving the traction and braking force of the tire.

Conventionally, a snow chain having such a function is made of a metal material so that the outer circumferential surface of the tire is wrapped by connecting a plurality of wires with spikes in the uniaxial direction between the wires having a predetermined length (the outer circumferential surface length of the tire) to be integrated. It has been proposed to place the pad using waste tire pieces in the short axis direction so as to be in close contact with the ground plane of the tire.

Alternatively, it is also proposed to separate the pad and the wire so that the user selectively binds the pad to the wire at the outer circumferential surface of the tire and tightly tightens the wire to integrate with the tire to promote safety in homogenous driving.

However, according to each snow chain described above, in addition to the increase in the unit cost on the manufacturing cost, there are some problems as follows.

First, the pads are positioned along the outer circumferential surface of the tire in a shorter direction in a shorter direction, and when the relationship between the pad and the tire is in contact with the ground, the pads and the tire are in contact with the ground. In the event of a sudden braking of the tire part in contact with the ice, the tire may slide as it is, which may cause a fatal danger.

Second, the chain is integrated with each wire is to provide a pad to form a hook in a practical relationship has a great deal of cumbersome due to the mounting bar, the hook is provided by fitting the left / right ends of the pad As a result of the prolonged use, the tensile force was lowered and the hook was detached, resulting in the separation of the pads.

Third, due to the low adhesion between the pad and the tire, a phenomenon in which the pad slips in the tire during driving and braking also occurred, and thus, the predetermined braking force was not exhibited.

On the other hand, in order to install a snow chain at night, a flashlight must be provided for more accurate mounting, and it is difficult to check whether the surrounding vehicle is a vehicle equipped with a chain when driving at night. Defensive driving was very difficult.

Therefore, the utility model registration application No. 97-13354 was proposed by the present applicant to "snow chain pad of a vehicle tire".

According to the above application, provided with a urethane material, provided with a pad having a plurality of friction protrusions on the outer surface, integrally formed hooks at both ends of the pad, and fixing the spikes of the metal to the protrusions, such The pad of the structure is provided with a fluorescent material and applied to the pad outer surface or mixed with the pad material.

However, in using the above improved pads, the following unexpected problems were included.

In other words, when the hooks at both ends of the pad are fixed to the wire, the binding state can be tightly fixed, thereby suppressing the occurrence of fluidity. This occurred, it takes too much time, it was difficult to change the position of the pad as needed.

Along with this, even when folded and stored, the volume of the pad is fixed, which is cumbersome in storage and movement.

Therefore, the coupling structure between the pad and the wire should be improved to include the convenience of the user according to the device and the usefulness in storage.

The present invention proposes to be able to be moved by a certain distance through the wire in the hook of the pad in order to meet the above requirements.
