Abstract

PURPOSE:To obtain a snow tire that is detachably attached easily to an outer peripheral part of an original tire by providing fixed braces on the outer peripheral part of an annulus ring-like tire while providing a hollow chamber that is fed and bled air or the like via a valve, inside of the tire. CONSTITUTION:A snow tire 1 is set at the inner diameter equal to the outer diameter of a original tire 5 to which this snow tire is attached, and formed in like an annulus ring. And fixed snow patterns or spike pins 2a and so on are provided on the tread face 2 on the outer periphery of the snow tire 1. Again, a hollow chamber 3 filled up with air, for example, is provided over whole width in tire section inside of the snow tire 1. Still a valve 4 through which fed and bled air, for example, is provided while a balancer 7 is provided on a side face of the snow tire 1. On using, the snow tire 1 is made to engage to the outer periphery of the original tire 5 by means of expanding the snow tire 1 with filling up air, for example, into the hollow chamber 3 from the valve 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a snow tire that is attached to the outer periphery of an automobile tire and used to prevent the wheels from slipping.

[Conventional technology]

BACKGROUND ART In automobiles, etc., slipping due to snow or ice formed on rough roads, especially in winter, makes it difficult to start and drive, which is extremely dangerous.

Therefore, a set of steel chains is usually wrapped around the wheels to prevent them from slipping.

[Problem that the invention seeks to solve]

Although the above slip stopper chain is durable, it is heavy and therefore inconvenient to handle.

Therefore, various anti-slip devices have been proposed that are relatively lightweight and easy to handle, even if they sacrifice some durability.

For example, several plates with a chevron-shaped cross section or short protrusions are attached around the wheel to prevent slipping, and a rubber plate with a length equal to the outer circumference of the tire is fitted with many chevron-shaped protrusions at intervals. tread. There are some that have a ring-shaped anti-slip plate with a snow tire pattern formed on its surface or pins embedded in it, which is then split into two and attached to the outer periphery of the tire.

By the way, even if these proposals have some effect, they are still inconvenient to handle, lack durability, and are difficult to attach and detach, making it difficult to keep the road surface in place even if it reaches unnecessary areas. There were drawbacks such as unavoidable damage, so not all products were necessarily satisfactory.

An object of the present invention is to provide a snow tire that solves these drawbacks and is extremely easy to install and remove.

[Means and effects for solving the problems] The snow tire according to the present invention is a removable snow tire that is attached to the outer periphery of a car tire and used to prevent the wheels from slipping.
A snow tire pattern is formed or a bottle is planted on the trend surface of the outer circumference, the diameter of the inner circumference is equal to the outer diameter of a normal tire, and the inner circumferential width of the tire is It is characterized by having a hollow chamber that expands and can be filled with air or gas through a valve provided on the side.

When installing the snow tire according to the present invention, the snow tire is taken out of the trunk of a car, fitted onto each tire, and filled with air or gas through the valve to a predetermined pressure. Can be used in the same way as tires.

Further, when removing the snow tire of the present invention, by opening the valve and letting out air or gas, the snow tire can be immediately removed from the original tire and stored in the trunk.

〔Example〕

Embodiments of the snow tire of the present invention will be described below based on the drawings.

As shown in FIGS. 1 and 2, the snow tire 1 of the present invention is somewhat flatter than the tire 5 mounted on the wheel 6, but can perform almost the same function as a conventional snow tire.

That is, a snow pattern 2a for preventing slipping is formed on the outer periphery tread surface 2, like a normal studless tire. Alternatively, a large number of pins may be installed to prevent slipping like a spiked tire. The inner diameter of this tire 1 is equal to the outer diameter of the original tire 5, and both ends are slightly bent downward on both sides so as to hold it from both sides of the tire 5 so that it will not easily come off when attached to the original tire 5. It is extending. Inside the tire 1 there is provided a hollow chamber 3 for filling with air or gas, which extends over the entire width of the tire cross section, and on the side of the tire there is a valve 4 for inlet and release of air or gas. On the diametrically opposite side, a portion of the tire extends to form a balancer 7.

In use, the snow tire 1 of the present invention is fitted onto the outside of the original tire 5 and filled with air or gas through the valve 4 to a predetermined pressure. Then, the air or gas filled in the hollow chamber 3 expands and is firmly fixed to the original tire 5. Therefore, the snow tire 1 of the present invention can be used in the same way as a normal snow tire. When the snow tire is no longer needed, air or gas is released from the valve 4, and the tire 1 becomes easily deformed, and the tightening force on the tire 5 is lost, so it can be easily removed from the tire 5 and stored in the trunk. can do.

〔Effect of the invention〕

The present invention has a somewhat smaller wall thickness than normal tires and is made of the same material, so it is not very heavy, yet it has the same durability as a conventional snow tire, and the inner diameter is the same as the outer diameter of the tire. It does not require much effort to attach and detach, it is easy to fill and release air or gas, and it can be attached and detached whenever necessary. Also, if you have several types of treads with different tread patterns, you can change them depending on the degree of snow and ice formation. Also, when you go out on a snow-free road, you can remove it immediately to prevent it from damaging the road surface and generating dust. Furthermore, it is more elastic, has no difference in stability, maneuverability, etc. from conventional replacement snow tires. In fact, because the total diameter of the tires is larger, when there is a large amount of snow, the tires are less likely to get buried in the snow, making driving even safer.
