Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle fixing device for cracking down on illegally parked vehicles or preventing theft of parked vehicles, and in particular, the movement of vehicles by restraining the rotation of wheels. The present invention relates to a vehicle restraining device for preventing the occurrence of a vehicle.

[Conventional technology]

In recent years, with the increase in the number of vehicles, it has become difficult to secure parking lots, especially in urban areas, and illegal parking has increased dramatically, causing not only traffic obstacles but also frequent traffic accidents caused by illegal parking. It has occurred. In order to solve such a problem, a method of installing a parking meter or the like has conventionally been adopted as a facility for parking vehicles on a specific road side for a fee, but this also cannot catch up with the increasing number of vehicles, In addition, since the parking time by the parking meter is limited to a very short time, there are many "illegal parking" vehicles that do not pay the parking fee, and there is a limit in controlling such vehicles.

Regarding such parking difficulties in urban areas, plans to reuse and reconsider the current urban idle land space are being considered,
As an emergency measure, do not allow illegal parking as described above,
In addition, there is a need for measures to prevent illegal parking, such as not allowing "escape".

Thus, the vehicle restraint proposed as a part of such measures includes a rotation preventing means for at least one wheel grounded on the ground, and prevents deflation of the tire and removal of the wheel from the axle. It is necessary to constitute a wheel disengagement preventing means and a locking / unlocking means for locking a state of being mounted on the wheel, and to have a simple and easy handling by a portable assembly type structure.

Conventionally, as this type of vehicle restraining device, Japanese Utility Model Laid-Open No. 62-114856
However, the invention discloses a structure disclosed in Japanese Patent Application Laid-Open Publication No. H11-260, in which a pair of brace blocks are connected to a chain extending along the outer peripheral surface of the tire and to the outer surface of the wheel while being connected to the chain. A shielding plate that is in contact with and shields the attachment portion of the wheel to the air inlet and the axle, and is fixed to the shielding member,
The structure is such that the wheel is fixed by a tightening member that clamps the wheel by the block.

[Problems to be solved by the invention]

However, in the above-described conventional vehicle restraining device, since the restraint on the upper portion of the wheel is performed only by the chain stretched along the tire outer peripheral surface of the wheel, the upper portion of the chain is fixed to the surface of the wheel. It is possible to remove the vehicle restraint device from the wheels by jacking up the vehicle body in that state, so the effectiveness as the device is impaired and the workability of mounting on the wheels is poor There was a problem.

The present invention has been made in view of the above problems,
An object of the present invention is to provide a simple vehicle restraining device having a structure that can be easily attached / detached and cannot be removed from the wheel unless it is unlocked after being attached to the wheel. It is.

[Means for solving the problem]

In order to achieve the above object, a vehicle restraining device according to the present invention is provided with a wheel fixing means for stopping the rotation of a wheel, and is integrally fixed to the wheel fixing means, and is disposed so as to be opposed to the diametrical direction of the wheel. The gist is that the pair of wheel holding means, and a fixed adjusting means for holding and fixing the wheel by pulling the pair of wheel holding means in mutually opposing directions, the wheel fixing means, One side or both sides of the wheel is grounded on the ground surface to support the wheel holding means at a desired height, and the pair of wheel holding means are each formed in an L-shaped plane cross section, and are substantially above the outer peripheral portion of the wheel. One or more projections are formed on the inner end surface of the side plate that is in contact with the center line, and the side plates located on the front surface side of the wheel are arranged so as to face each other in the diametrical direction of the wheel. The fixed adjustment means is
It is formed to have a size to cover the wheel mounting portion for the tire air inlet and axle, and on the surface side of the wheel holding means on the surface of the shielding plate that slidably fixes the front side plate of the wheel holding means. The side plates located on each other are connected to each other by a connecting screw mechanism that stretches or extrudes on the facing axis, and the rotation of the connecting screw mechanism is appropriately shielded and fixed by a cover or a stopper.

Further, the wheel fixing means may be provided with a locking block so as to prevent the rotation of the wheel.

Furthermore, a receiving plate for holding the wheel in the width direction may be formed on the side plate constituting the wheel holding means, and the holding width may be appropriately adjusted according to the width of the wheel.

[Action]

According to the vehicle restraining device of the present invention, when the screw shaft is appropriately rotated by a crank or the like, the protrusions protruding from the side plates of the wheel holding means bite into the outer periphery of the tire, firmly holding the wheel, and the wheel fixing means. The lower end of the wheel contacts the ground to stop the downward rotation due to the rotation of the wheel. Further, the rotation of the screw shaft is stopped by the stopper, and the release of the fixing portion is prevented by the locking and fixing means, whereby the detachment of the device is prevented, and the vehicle can be restrained.

In addition, since the mounting portion of the wheel with respect to the axle and the air inlet of the tire are covered with the shielding plate, the wheel can be removed from the axle by removing the wheel from the axle or removing the air from the tire. It cannot be removed from.
