Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a tire cover that is attached to, for example, a vehicle running on snow to prevent slips and the like and improve driving safety.

(b) Conventional technology Conventionally, when driving on roads with frozen or snow-covered roads, safety is significantly impaired due to slips, etc., so anti-slip attachments (tire chains, etc.) have been installed on the circumferential surface of tires. Recently, the problem has been dealt with by equipping tires with processed tires (snow tires, spiked tires, etc.).

Regarding tire chains, the material has been improved from steel to rubber, and various improvements have been made. For example, as seen in Japanese Utility Model Application Publication No. 49507 of 1982, there is a device characterized by having a rubber strip shaped like a mesh and having rubber protrusions provided at the cross portion. Also,
Improvements in spiked tires and tire covers, such as those seen in Utility Model Application Publication No. 180607 of 1980, are made by making the elastic body into a lattice shape, and furthermore, by providing a plurality of through holes at appropriate locations in the ground contact area of the lattice ribs. Tire anti-slip devices featuring spike pins inserted and attached to the lattice ribs, etc.
Improvements have been made not only by changing the material of the anti-slip part, but also by making it double as a spike pin, aiming for a synergistic effect.

(c) Problems to be solved by the invention However, such improvements in the prior art are no longer able to deal with current social problems. This is because, as mentioned earlier, these snow chains and spiked tires that are intended to have an anti-slip function are intended for use when driving on frozen or snow-covered roads; It is normal for it to take a considerable amount of time and trouble to attach and detach. For this reason, as a practical matter, it is often the case that the vehicle is driven on a normal road surface without any snow (hereinafter simply referred to as a normal road surface) with these anti-slip parts attached. Particularly regarding spiked tires, in some regions some cars are always equipped with them during the winter.

On the other hand, when running on a normal road surface with a metal chain, not only does it damage the road surface, but if the condition continues for a long time, it will break due to frictional heat and break. Further, although the rubber (resin) version developed from this has been improved, it is less effective than the metal version when driving in snowy conditions.

On the other hand, it has more effects than metal chains,
Spiked tires do not break even when driven on normal roads. However, while these spiked tires do not have to worry about being damaged when driven on normal roads, they do damage the road surface and spread dust, causing pollution problems. In places such as Hokkaido and Sendai, while recognizing the effectiveness of spiked tires, they were unable to address the social problem of dust pollution and even banned their use.

Although the technologies mentioned above have been improved to solve many of these problems, none of them can deal with all conditions (problems); for example, the use of spiked tires has problems with dust pollution. However, spike pins made of elastic members still have the problem that they cannot be expected to be sufficiently effective or that they themselves wear out.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an anti-slip device that does not degrade the effectiveness of conventional metal chains and does not cause dust problems even when spike pins are used.

(d) Means for solving the problems The structure of the present invention for achieving the above object will be explained using FIGS. 1 to 3 corresponding to the embodiment. The tire cover according to the present invention is made of a size large enough to cover the ground contact part of the tire and the side surface of the tire adjacent to the contact part, like a conventional metal chain. Furthermore, the overall structure is made of non-metallic materials such as rubber, synthetic resin, etc.
Its shape is mesh-like, and anti-slip aids are attached at the intersections. Further, between the ground contacting part of the tire and the tire body, an elastic sheet-like material having a certain thickness is bonded to the mesh cover over the entire circumference of the tire.

The sheet material is provided with at least one row of suction cups made of an elastic material around the entire circumference of the tire, and spike pins are provided in the suction cups.
Further, if a space is provided above the mounting portion of the spike pin and the suction cup, the buffering effect will be improved when the spike pin contacts the normal road surface.

(e) Effect The present invention uses the above-mentioned means to prevent snow accumulation,
It is obvious that it has an anti-slip effect on frozen road surfaces. Furthermore, when driving on normal roads,
Since the sheet-like material has a certain thickness and is an elastic material, when the anti-slip aid provided at the intersection of the net-like cover comes into contact with the road surface, it has a cushioning effect to reduce friction, and the spike pins Because it is inside a suction cup made of elastic material, the first thing that comes into contact with the road surface is usually the suction cup, and when the spike pin comes into contact with the road surface, the force is buffered upward, and there is almost no friction with the road surface, and these two It is possible to prevent the anti-slip device from scratching the road surface and causing dust pollution.

(f) Embodiment An embodiment of the present invention will be described below. 1 is a suction cup provided on an elastic sheet material 4, 2 is a mesh tire cover that covers the entire tire, and 3 is a suction cup provided at the intersection of the meshes. It is a non-slip aid. Further, 5 is a tire body, 6 is a spike pin, and 7 is a space provided above the spike pin.

As shown in FIGS. 1 to 3, the elastic sheet material 4 has a certain thickness so that the suction cup 1 can be attached thereto, and its width is smaller than the width of the tire. Further, the anti-slip aids 2 provided at the intersections of the mesh are positioned above the suction cups, and the spike pins are also positioned shorter than the road contact surface 1a of the suction cups. The size of the shock absorbing space 7 of the spike pin, which can be provided as needed, is supplementarily determined by the elastic modulus of the suction cup.

Furthermore, the effect can be further improved by inserting an elastic impact member 8 into the space 7 as shown in FIG.

5 and 6 are examples of the mesh shape of the mesh tire cover, and the shape is not particularly specified for its effect.

(h) Effects of the device Since the device has the above-mentioned configuration, it not only provides sufficient anti-slip properties on snowy and frozen roads, but also eliminates the risk of causing dust pollution, which has become a social problem in recent years. It has the extremely useful effect of being able to run on normal roads, and its strength and durability are superior to metal chains and the like.

Furthermore, since the tire cover provided in the present invention is not a result of processing the tire itself, it also has the advantage that, like a tire chain, it can be used only when necessary for normal tires.
