ABSTRACT:
A retractable wheel lock assembly for permanent mounting to a vehicle having a pair of proximately spaced tandem wheels. The wheel lock assembly includes a security tube including two tubular members disposed for relative axial movement. Structure is provided for moving the second tubular member from a first, retracted position to a second, extended position relative to the first tubular member. A wedge-like brake member having two angularly spaced surfaces is carried by the second tubular member for movement therewith. Structure is provided for mounting the wheel lock assembly to the frame of the vehicle so that an axial center line of the security tube is generally vertical and the wedge-like brake member is disposed between the tandem wheels of the vehicle such that the angularly spaced surfaces engage a portion of the tread surface of each wheel when the second tubular member is in the second, extended position.
