JPH10236113A - Antislip piece for studless tire - Google Patents

Abstract

PROBLEM TO BE SOLVED: To decrease a slippage at the time of travelling on a frozen road without removing a tire by bonding a top shaped member in which an antislipping material obtained by crushing a non-metallic material is mixed to the groove of a tread surface by means of an adhesive agent. SOLUTION: A top-shaped member corresponds to the sectional shape of a groove 2A on the tread surface 2 of a tire having no stud and is formed with a prescribed length. The top-shaped member comprises an upper part 1A1 and a lower part 1A2. An antislipping material is mixed in the upper part 1A1. The top shaped member is bonded to the groove 2A of the tread surface with a prescribed space by an adhesive agent 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-slip piece for a studless tire. 1. Used as a substitute for spiked tires. 2. Slip can be reduced when traveling on an ice burn road surface. 3. Unlike spikes, there is no need to remove.

[0002]

2. Description of the Related Art Heretofore, this type is as follows. 1. There are tire chains and net chains. 2. There is a detachable spike pin.

[0003]

The above-mentioned prior art has the following problems. 1. Tire chains, net chains, etc. take time to attach and detach, and women are shunned. It suddenly breaks when running with the chain attached, which can damage the car body. 2. Spiked tires cut road surfaces and cause car dust pollution. 3. The detachable spike pin takes a very long time to detach. 4. At present, studless tires are the mainstream, and especially in the area 2 to 30 meters before the intersection, an ice burn is used. The present application has been made in view of such problems of the conventional technology, and an object of the present invention is to provide a device that can solve the above-described problems.

[0004]

Means for Solving the Problems In order to achieve the above object, the present invention is as follows. According to the present invention, the studless tire to be mounted has a substantially U-shaped cross section and a predetermined length corresponding to the cross-sectional shape of the groove 2A formed in the substantially U-shaped cross section in the tread surface 2 of the studless tire. In the piece 1A, the piece 1A is made of natural or synthetic rubber of the same quality as the studless tire, and the piece 1A has an upper portion 1A1 and a lower portion 1A2.
The upper part 1A1 is mixed with a non-slip material 1A11 formed by crushing a non-metallic material such as ceramic, marble, coke, shells, and rocks. It is an anti-slip piece for a studless tire configured to be adhered with an adhesive 3 at a predetermined interval.

[0005] In this case, it can be configured as follows. The height H of the lower part 1A2 of the piece 1A is
Height H1 of platform 2B formed in groove 2A
It is configured lower.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. Reference numeral 1 denotes an anti-slip piece for a studless tire according to the present invention. Reference numeral 2 denotes a tread surface of a known studless tire on which the anti-slip piece 1 for a studless tire is mounted.
A known groove 2 </ b> A having a U-shaped cross section is formed in the lateral direction and the oblique direction. Reference numeral 2B denotes a known platform provided at a predetermined position in the groove 2A for notifying the tire replacement time. The anti-slip piece 1 for a studless tire of the present invention is fitted in such a groove 2A at a predetermined interval.

[0007] Anti-slip piece 1 for studless tires
In a piece 1A having a substantially U-shaped cross-section and a predetermined length corresponding to the cross-sectional shape of the groove 2A, the piece 1A is made of a natural or synthetic material of the same quality as a known studless tire. It is made of rubber. The piece 1A has an upper portion 1A1 and a lower portion 1A2.
The upper portion 1A1 includes a non-slip material 1A11 formed by crushing a nonmetallic material such as ceramics, marble, coke, shells and rocks. The piece 1A
It is configured to adhere to the groove 2A of the tread surface 2 with the adhesive 3.

[0008]

【Example】

1. The height H of the lower portion 1A2 of the piece 1A is lower than the height H1 of the platform 2B formed in the groove 2A. Therefore, even if the tread surface is worn and the platform comes to the surface, a part of the piece 1A remains, so that the anti-slip function is performed. 2. The hardness of the piece 1A is about 55 to 60 degrees.
(It is configured to be slightly harder than the hardness of the studless tire.) It is effective to attach six or eight pieces at predetermined intervals to the ground friction surface during running on the tread surface. 4. Since most current studless tires have grooves, the shape is the same so that it can be used with any tire,
There are several sizes.

[0009]

Since the present invention is configured as described above, the following effects can be obtained. 1. Since the pieces 1A are arranged at predetermined intervals in the groove,
When braking is performed on a frozen road surface, a streak is formed on the frozen road surface due to the effect of the anti-slip material, and the effect of anti-slip can be exhibited. 2. During normal running, the anti-slip material is buried at a position slightly shallower than the tire surface. However, when the brake is applied, the tire is weighted. To cut into the burn surface, 3 of normal studless tires
It can be stopped at a braking distance of 2 / min. 3. Since the bonding surface of the piece has a substantially U-shaped cross section so as to fit into the groove, it can be securely bonded to the groove. 4. Since the upper part 1A1 contains a non-slip material, it has a synergistic effect with the studless tire. As a result, A. When a brake is applied by an ice burn, the vehicle stops at a shorter distance than before. B. Does not shake too much when the brake is applied. C. The effectiveness of the engine brake improves. In this case, it is more effective not to lock the brake, and the pumping brake works more effectively.
