Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tire cover for preventing slips, which is used in place of a tire chain or the like during the snowy season to prevent slips.

(Prior Art) During the snowy season, tire chains are attached to regular tires, or spiked tires or snow tires are used. However, tire chains must be installed and removed depending on the presence or absence of snow, and they also generate large amounts of vibration and noise, and the chains cause damage to the tire road surface.
Even with spiked tires, damage to the paved road surface is considered a problem, and tires need to be replaced depending on whether or not it snows. Snow tires have good driving performance on snow-covered roads, and have better vibration and noise while driving than tire chains, but when driving on regular paved roads, they are less effective at high speeds than regular tires. There are problems in that the steering stability during running is poor, and because the tread surface has deep grooves, vibration and noise are large during running.

(Purpose of the Invention) The present invention was made in view of the above-mentioned circumstances.A vehicle is equipped with regular tires throughout the year, and during the snowy season, the tread portion of the snow tire has the same function as the tread portion of the snow tire. A slip-preventing tire cover consisting of a tread portion and a fixing member made of heat-shrinkable rubber or heat-shrinkable synthetic resin that covers the shoulder portion, sidewall portion, and outer surface of the rim portion on both sides of the tread portion is mounted on a regular tire. This ensures driving safety on snowy or icy roads, and by removing the anti-slip tire cover and using regular tires during non-snowy seasons, it provides stable driving throughout all seasons. Securing sexuality and
The purpose is to reduce vibration noise.

(Example) An example of the anti-slip tire cover according to the present invention will be described based on the drawings.

FIG. 3 schematically shows a typical tire that is installed on a vehicle throughout the year. 11 is the tread section, 12
a is the shoulder part, 12b is the side wall part, 1
3 is a rim portion.

FIG. 1 shows a tire cover for preventing slips according to the present invention. The annularly formed tread portion 1 is formed in the same shape and material as a snow tire, and has the same function as a snow tire. 2 is fixed to the tread part 1 and extends on both sides of the tread part 1 in order to fix and hold the cover itself on the surface of a normal tire;
This is a ring-shaped fixing member made of a thin plate of heat-shrinkable rubber or heat-shrinkable synthetic resin. The portion 2a of the fixing member 2 is the shoulder portion 12a.
In addition, the portion 2b is brought into close contact with the sidewall portion 12b, and the portion 2c is brought into close contact with the outer surface of the rim portion 13 by heating. The central portion 2d is integrally connected to the inner surface of the tread portion 1 by pasting, welding, or the like. 3
is a heat-generating agent applied or fixed to the surface of the fixing member 3. For example, phosphorus chloride, potassium chlorate, calcium carbonate, zinc oxide, etc. are mixed with glass powder, silica powder, etc. as a regulating agent and kneaded with glue or the like. They are also coated and fixed. 4 is exothermic agent 3
It is an anti-oxidation coating.

Using this anti-slip tire cover, the tread portion 1 is fitted onto the tread portion 11 of a normal tire that is installed on a vehicle throughout the year, and
When the fixing member 2 is brought into close contact with the shoulder portion 12a, the sidewall portion 12a, and the rim portion 13, and the anti-oxidation coating 4 is removed, the exothermic agent 3 generates heat, the fixing member 2 is thermally contracted, and the shoulder portion 12a is removed. ,
It is fixed in close contact with the sidewall portion 12b and the rim portion 13.

(Structure of the Invention) The anti-slip tire cover according to the present invention includes:
The fixing member is composed of an annular tread portion having the same function as the tread portion of a snow tire, and a fixing member made of heat-shrinkable rubber or heat-shrinkable synthetic resin coupled to the tread portion and extending on both sides. A fixing agent is fixed on the surface of the plate.

(Effects of the Invention) Therefore, the anti-slip tire cover according to the present invention is fitted onto a normal tire, the fixing member is brought into close contact with the tire cover, and then the tire cover is fixed to the normal tire by generating heat with a heat generating agent. can,
During the snowy season, slip prevention is done in place of tire chains, etc., and during the non-snowy season, the tire cover can be easily removed and regular tires can be used, ensuring steering stability throughout the year and reducing vibration and noise. can be reduced.
