ABSTRACT:
A vehicle detention device provides a pair of stopper blocks, where one of the stopper blocks moves on a guide shaft relative to the other stopper block secured to the guide shaft. A locking device is provided in order to prevent the movable stopper block from shifting away from a tire so that both the stationary and movable stopper blocks remain in contact with the tire at both sides of ground contact point to prevent rotation of the wheel with the tire mounted thereon. Using a pair of chains, the wheel is secured and placed under detention with the stopper blocks closely held in contact with the tire. Since the mechanical components necessary for releasing the tire and wheel are fully concealed by a key-actuated cover unit, no one can readily remove the vehicle detention device from the restrained vehicle without operating a proper key, thus securely detaining the vehicle.
