JPH09300902A - Slip preventing device for automobile - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an automobile tire slip preventing device that can adjust the height of non-slip parts with simple operation without needing to attach/ detach the device. SOLUTION: A rotary disk 1, retaining bars 2 and non-slip parts 3 are built in a tire, and the rotary disk 1 is rotated to adjust the height of the non-slip parts 3 protruded from the tire surface. Switching at a boundary between an icy road and the normal road surface can thereby be performed in a short time with simple operation so as to be safe.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention A method for preventing a vehicle from slipping on a snowy road. [Technology of Rairai] 1. Traveling with tire chains attached. 2. Run with snow tires or studless tires. [Problems to be Solved by the Invention] 1. It takes time and effort to attach and detach the tire chain. 2. Snow tires and studless tires do not have a complete anti-slip effect on ice and snow roads. [Means for Solving the Problems] When the present invention is installed: 1. Since the device is not required to be attached and detached, and the slip prevention portion can be adjusted to “high” and “low” by a simple operation. It takes time and effort to switch between the snow and snow roads and the normal road surface in Sakai. 2. When traveling on normal road surface, the non-slip part does not come into contact with the road, so it is possible to incorporate highly effective anti-slip. BEST MODE FOR CARRYING OUT THE INVENTION Referring to FIG. 1, when the turntable (1) is turned to the right, the tension rod (2) prevents the sliding (3) from slipping (3) above the ground contact surface of the tire. It is pushed out and it becomes a form that can run on ice and snow roads. When the vehicle comes to a normal road surface, turn the turntable (1) counterclockwise to return the anti-slip (3) to a position lower than the contact surface of the tire. Explaining FIG. 2, it is a form of a method of extending the expansion ring (5) and pushing out the anti-slip part (3), including the screw and the gear (7).
Perform expansion / contraction operation using. [Embodiment] FIG. 3 shows an embodiment in which the expansion ring (5) is expanded and contracted using the screw (8). FIG. 4 shows an embodiment in which the expansion ring (5) is expanded and contracted using a wrench. [FIG. 5] shows an embodiment in which the expansion ring (5) is expanded and contracted using the middle folding arm (6). [FIG. 6] [FIG. 7] [FIG. 8] are embodiments of a method of pushing out the non-slip portion by a rotating disk. [Advantages of the Invention] Since switching between the ice and snow road and the ordinary road surface in Sakai can be performed by a simple operation in a short time, it is safe.

BRIEF DESCRIPTION OF THE DRAWINGS [FIG. 1] [FIG. 3] [FIG. 4] [FIG. 6] are for a single tire. [Fig. 2] and [Fig. 5] are for both single tires and double tires. [Fig. 7] and [Fig. 8] are for double tires.
