Abstract

PROBLEM TO BE SOLVED: To reduce influence and prevent a serious accident when a tire for an automobile and/or a motorcycle is punctured. SOLUTION: A backup tire 1 installed in a wheel 2 is provided in a cavity of a tire 3 to reduce influence when the tire 3 is punctured.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accident prevention device which is mounted on a wheel inside a tire of an automobile or a motorcycle to ensure safety when the tire is punctured.

2. Description of the Related Art In most of conventional wheel devices for automobiles and motorcycles, tires into which air is injected are used. However, the inside of the tire is hollow, and the ground side surface of the wheel is used. Has a concave shape at the center.

[Problems to be Solved by the Invention] In the prior art, when the tires burst or puncture, the shape of the wheels changes remarkably, and a sudden force is applied. This could lead to a serious accident.

[0004] The present invention, even if the tire punctured,
It is an object of the present invention to provide a device that reduces the influence on traveling and prevents accidents.

[Means for Solving the Problems] In order to achieve the above object, in the accident prevention apparatus of the present invention, a backup tire is mounted on the outer periphery of the wheel so as to fit in the space inside the tire, and the tire is punctured. In this case, the backup tire can perform the function of substituting the tire even when the tire is damaged, so that the influence of the puncture can be reduced.

[0006] The backup tire to be mounted on the wheel of the present invention does not impair the cushioning of the tire in the tire.
In addition, it is effective to mount the tire on the outer periphery of the wheel so as to minimize the impact at the time of puncturing of the tire.

[0006] In addition, in order to facilitate mounting on a wheel, the backup tire has an inner diameter which is increased by injecting air, and after being fitted on the outer periphery of the heile, it can be fixed by removing the air.

As another method for facilitating charging of the backup tire to the wheel, a part of the backup tire can be opened and closed, and after mounting, it can be fixed with a fastener, or a part of the backup tire can be expanded and contracted. So that
There are methods to make it easier to wear.

[Embodiment of the Invention] An embodiment of the invention will be described with reference to the drawings based on an embodiment. In FIG. 1, a backup tire 1 is mounted on a wheel 3 in a space inside a tire 2. ing.

In this embodiment, the backup tire 1
When the tire 2 is punctured, the backup tire 1 supports the vehicle weight in place of the tire 3 and reduces the state change due to the puncture when the tire 2 is punctured.

In the present embodiment, the method of mounting the backup tire 1 to the wheel 2 is similar to the method of mounting the normal tire to the wheel, by expanding the backup tire 1 using equipment or tools and inserting it into the wheel. , To be fitted.

In order to facilitate the mounting, a cavity is formed inside the backup tire, the inside diameter is enlarged by injecting air into the backup tire, and after inserting the wheel into the wheel, the air is pulled out to be pressed against the wheel. You can also make backup tires. As a backup tire 1 provided with another mounting simplification means, a part of the backup tire can be opened and closed, and the wheel 2
, And a backup taya which is closed after the insertion and secured with a stopper.

[Effects of the Invention] Since the present invention is configured as described above, it exhibits the effects described below.

[0013] By providing a backup tire mounted on the wheel in the space in the tire, when the tire is punctured, the backup tire replaces the punctured tire, thereby reducing the influence of the puncture and making it impossible to run and steer. It is possible to prevent or suppress a serious accident.
