Portable anti-theft alarm and locking device for vehicles

A portable anti-theft device for vehicles having a steering wheel which includes a rim to which the device can be locked with a part thereof projecting therefrom to limit the free angle of rotatability of the steering wheel relative to fixed internal structures of the vehicle to thereby limit the drivability of the vehicle, the device comprising:

• a bar having first and second opposite ends;
• means for attaching said bar to a section of the rim of a steering wheel of a vehicle so as to rigidly support the device on the rim with the bar tangent to, and with at least one of the ends displaced tangentially from, the section of the rim to which the bar is attached a distance sufficient to contact the fixed internal structures of the vehicle when the steering wheel is rotated;
• and
• means for locking the attaching means to thereby limit the rotatability of the steering wheel and the drivability of the vehicle.

• a bar having first and second opposite ends and formed at least in part of a wall open along one side of a portion of the bar to define an interior thereof, said portion having an inside dimension greater than the diameter of the steering wheel rim whereby the bar is positionable against the steering wheel rim such that the inside of the wall is against the outside of the rim and the bar is tangent to the rim with at least one end of the bar displaced from the steering wheel a distance sufficient to contact the internal fixed structures of the vehicle when the steering wheel is rotated;
• a clamping member movably connected to said portion of the bar, the member being moveable to a closed position in which the member and the wall surround and clamp the bar to the rim of the steering wheel to thereby rigidly support the device thereon and to an open position in which the bar may be positioned on and removed from the rim;
• and
• means at least in part on said portion of the bar for locking the member in its closed position to lock the device to the steering wheel to thereby limit the rotatability of the steering wheel and the drivability of the vehicle.
