BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip member for a tire of an automobile, in which two adjacent cross-slip members abutting on the outer peripheral surface of the tire are joined at the central portion of the outer peripheral surface of the tire. By doing so, it is an object to configure the cross pattern on the ground contact surface (tire outer peripheral surface) as a whole to have a continuous pattern of a hexagonal shape instead of a simple ladder shape as in the past.

2. Description of the Related Art Anti-skid automobiles have been used less frequently as road maintenance has progressed in recent years, but it is considered to be completely defenseless against snow in winter. On the other hand, in terms of automobiles, on the other hand, various types of automobiles are manufactured in general passenger cars, and it can be said that the automobile manufacturing industry responds to various needs. Under such circumstances, recently, the width of the tire has been gradually widened, and the flatness ratio has been reduced.

This seems to be an inevitable tendency to seek stability at higher speeds while the width of the automobile is regulated, but this result is also surprising for the anti-skid device of the automobile. A trend is emerging.

That is, if the stability of running is required while the vehicle width is regulated, the wheels naturally tend to be attached to the outside, and if a wide tire has good maneuverability, this tendency will occur. Are increasingly encouraged.

As a result, the distance between the tire and the body or parts around the wheel is becoming smaller and smaller.
Not only chain-like chains certified as "S", but also materials for non-metallic non-slip devices that have been developed in recent years have limitations in reducing the thickness due to specific strength, etc. In response to the above, a cable-based non-slip device has been spotlighted as a device that overcomes structural problems and strength problems.

The applicant has conventionally manufactured and supplied to the market a cable type product mainly composed of such a wire and a coil. However, in view of such a situation, a passenger car having a function similar to that of a sports car is provided. The challenge is to provide a product that has sufficient steering performance even on a steep curve with a small curvature, such as a road around a ski resort, and has little slippage even when the vehicle starts at a high rotation speed close to 3000 rotations. became.

In order to meet such a problem, the cross pattern of the cross anti-slip member of the anti-slip device is not a mere ladder shape as in the prior art, but the adjacent parallel cross anti-slip members are provided at substantially the center of the outer peripheral surface of the tire. It was experimentally recognized that the ones having a tortoiseshell pattern combined with the parts have high performance.

However, in such a structure, the connecting portion is the central portion of the tire, which is also the place where the centrifugal force and frictional force of the wheels are most strongly received, and the braking performance on snow and ice and the snowless road. If you try to increase the installation area of the rubber part of the tire in order to share the climbing performance, the connecting part of the center part of the cross-skid member will inevitably become an acute angle and it will be bent in a sharp angle direction, which is inevitable. Although it was known that the tortoise shell type was superior in steering performance and the like from the past, this problem could not be solved and it could not be put to practical use.

In order to form the cross pattern of the cross anti-slip member in a hexagonal shape, it is sufficient to join adjacent central portions of the cross anti-slip members arranged side by side at a predetermined interval to each other. Like this, this part is always struck on the ground by a large centrifugal force, so the damage is more noticeable than other parts.Therefore, in order to prevent this, there is a special fitting and a mounting method with a special structure. Will be needed.

It is a technical object of the present invention to solve the above problems and provide a glaze-type tire anti-slip device excellent in practicality.

[0011]

The gist of the present invention will be described with reference to the accompanying drawings.

Side members 2 which come into contact with both inner and outer side surfaces 1a and 1b of the tire 1 are arranged side by side, and a large number of cross-skid members 3 which come into contact with the outer circumferential surface 1c of the tire 1 are provided between the side members 2 and 2. In a tire anti-slip device configured to connect end portions of each side member 2, a fitting member 5 is fitted to a wire member 4 to form the cross anti-slip member 3, and adjacent cross sliding members are formed. A cross connecting member 6 that connects the stop members 3 to form a cross pattern of the cross anti-skid member 3 on the tire outer peripheral surface 1c in a substantially hexagonal shape is installed between the cross anti-slip members 3 and 3. At least two connecting portions between one end side of the and the one cross-skid member 3 are provided at a predetermined interval, and the fitted member 5 is arranged between the connecting portions, and the diameter of the fitted member 5 is cross-connected. Larger than the diameter of the connecting portion of the member 6 Those of the slip instruments of the tire, characterized in that there was boss.

[0013]

[Function] Each side member 2.2 is attached to both inner and outer side surfaces 1 of the tire 1.
The outer surface 1c of the tire 1 is provided with the cross-slip member 3 which is in contact with the side members 1a and 1b and is arranged between the side members 2 and 2 in a continuous hexagonal shape.
Abutting against each other, connecting the end parts of the side members 2 and 2,
Attach the product to Tire 1.

As shown in FIG. 1, the cross-slip member 3 is disposed between the side members 2 and 2 in a substantially continuous hexagonal shape and comes into contact with the outer peripheral surface 1c of the tire 1.

Therefore, for example, because the snow on the ground contact surface is continuously squeezed in or ground braking is performed, the climbing performance and braking performance are improved, noise and vibration are suppressed, and riding comfort is improved.

Moreover, the adjacent cross-slip members 3 are adjacent to each other.
A large fitting member 5 is placed between the connecting portions of the cross coupling member 6 and the cross coupling member 6 that connect the three and form the cross pattern of the cross non-slip member 3 in a continuous hexagonal pattern. Therefore, the continuous cloth member 6 does not come into direct contact with the ground contact surface strongly, resulting in excellent durability.

That is, if the cross anti-slip member 3 is simply connected, the cross anti-slip member 3 has a sharply pointed shape with respect to the traveling direction of the tire 1, and the cross anti-slip member is formed by such a conventional simple connecting method. The fitting member 5 fitted to the wire 3 is pushed to both sides, and the wire member 4 of the cross-skid member 3 is pushed.
Is not protected, the cross connecting member 6 is worn, and the cross anti-skid member 3 itself is subjected to an extreme concentrated stress due to an extreme bending, so that the cross connecting member 6 is
In addition, the cross-slip member 3 has poor durability and cannot be put to practical use, but the present invention solves such a problem.
