ABSTRACT:
An anti-theft security device, attachable to various types of parked vehicles, such as motorcars, motorcycles, light-aircraft, etc.; said device having a preferred wedge shaped profile as viewed installed from the wheel axial direction, and having clincher like appendage elements extending radially inwardly therefrom toward the wheel-axle on both opposed sides of the tire and rim-flange in a jaw like manner, thereby rendering the vehicle essentially immobile until said security device is simply detached by the vehicle-owner through means of a distensible-jaw element which is released by an integral latch/lock member; including an optional electronic audio-alarm provision whereby intimate contact between tire-tread and the armature/wedge-ramp acts to detain a switch-lever interconnected with the said lock, so that attempted forced removal of the wheel-immobilizer assembly activates an electronic audio-alarm circuit of substantially conventional design powered by enshrouded d.c.-battery current, which may be self-contained or remote-controlled via umbligal-cord plug-in arrangement; hence, an inexpensive portable anti-theft wheel-chock, having no installation-cost in the self-contained version.
