Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle restraint system for restraining a wheel of an illegally parked vehicle and restraining the wheel of the parked vehicle to prevent the vehicle from moving.

[0002]

2. Description of the Related Art Conventionally, as a vehicle restraint system of this type,
For example, the one disclosed in Japanese Utility Model Laid-Open No. 62-114856 is known, and the device disclosed in the publication is a pair of car stop blocks that come into contact with the outer peripheral surfaces of the tires of the wheels, and the above-mentioned tires. A connecting member that is stretched along the outer peripheral surface and connects the blocks, and is connected to the connecting member and is in contact with the outer peripheral surface of the wheel, and a tire air injection hole of the wheel and a mounting portion to the wheel. And a tightening member that is fixed to the shield member and that clamps the wheel in a sandwiched manner by the block.

[0003]

However, in the structure of the conventional vehicle restraint device, the upper portion of the wheel is restrained only by the connecting member stretched along the outer peripheral surface of the tire. The upper part of the wheel can be removed to the front side of the wheel, and the vehicle restraint device can be easily removed from the wheel by lifting the vehicle with a jack or the like in that state, and the effect as the vehicle restraint device cannot be exerted. There was a problem.

The present invention solves such a problem. The vehicle restraint device cannot be easily removed from the wheel without a key, the construction is simple and the work for attaching to the wheel is easy, and the vehicle restraint device is inexpensive. It is intended to provide.

[0005]

Means for Solving the Problem To solve this problem, the present invention is configured such that one locking block attached to a guide shaft can move the other locking block perspectively along the guide shaft. Lock means for preventing the other locking block from moving away from the tire while both locking blocks are in contact with the tire on both sides of the ground contact point with respect to the rotation direction of the wheel. The stop block is provided with a chain for tightening and restraining the wheel by straddling it from the inside of the wheel to the outside in an X shape with both locking blocks in contact with the tire, and hooking the end of the chain.

[0006]

With this structure, the wheel is tightened and restrained by the chain in a state where the pair of locking blocks are in contact with the tire on both sides of the ground contact point with respect to the rotation direction of the wheel, and the tightening means is released. Since the hook and the hook are covered with a cover with a key, the vehicle restraint device cannot be easily removed from the wheel without the key, and the vehicle can be restrained surely. In addition, the vehicle restraint device of the present invention has a simple structure, the mounting work for restraining the wheel can be easily performed, and the vehicle restraint device can be provided at low cost.
