Abstract

A portable antitheft locking mechanism for a motor vehicle steering wheel and brake pedal, e.g., a J-bar, having plural lighting elements, such as light emitting diodes, which generally indicate the profile of the locking mechanism so that it may be seen in darkness before forcible entry. The J-bar includes an independent source of power, such as a battery, which energizes the lighting elements either when the J-bar engages the vehicle member or when the access lock is secured, or both. The lighting elements provide means to inform the thief of the J-bar during darkness so as to deter his ill-intended efforts and spare the owner of unnecessary physical damage resulting from forcible entry. The J-bar preferably includes contact switch element which closes upon engagement with the steering wheel and/or a microswitch responsive to securement of an access lock on the mechanism to activate the lights thereby to conserve source when not in use. The lighting elements may be energized continuously, periodically, or sequentially. A photoswitch may also be employed to deactive the lighting elements during daylight conditions.

Claims

1. A portable steering wheel locking mechanism having a profile for use with a motor vehicle having a steering wheel and a brake pedal, said locking mechanism comprising:

an elongated member having opposed first and second ends, brake pedal engaging means disposed on the first end of said elongated member for coupling the brake pedal of the vehicle,

steering wheel engaging means disposed on the second end of said elongated member for coupling the steering wheel of the vehicle,

access locking means having secured and unsecured positions and also being disposed on the second end of the elongated member for securing the locking mechanism in place, and illumination means for signalling presence of said steering wheel locking mechanism with said motor vehicle, said illumination means including a source of power, luminous means disposed on said locking mechanism and powered by said source of power for visually indicated the profile of said locking mechanism, and condition responsive means for sensing engagement of said locking mechanism and for activating said source of power to energize said luminous means,

said luminous means further comprising a plurality of light emitting diode elements disposed on said locking mechanism and periodic lighting means for periodically activating said diode elements thereby to conserve power during operation.

2. A portable locking mechanism as recited in claim 1 wherein said condition responsive means comprises switch means responsive to engagement of said steering wheel engaging means with said steering wheel thereby to activate said source of power only when the locking mechanism is in use.

3. A portable locking mechanism as recited in claim 1 wherein said condition responsive means comprises switch means responsive to the secure position of said access lock thereby to activate said source of power.

4. A portable locking mechanism as recited in claim 1 wherein said luminous means includes means to effect periodic flashing of said light emitting diode elements.

5. A portable locking mechanism as recited in claim 1 wherein said luminous means includes means to effect sequential activation of said light emitting diode elements to indicate the profile of said locking mechanism.

6. A portable locking mechanism as recited in claim 1 further comprising photodetector means for sensing daylight conditions and for deactivating said illumination means thereby to conserve said source of power.

7. A portable steering wheel locking mechanism having a profile for use with a motor vehicle having a steering wheel and a brake pedal, said locking mechanism comprising:

an elongated member having opposed first and second ends,

brake pedal engaging means disposed on the first end of said elongated member for coupling the brake pedal of the vehicle,

steering wheel engaging mean disposed on the second end of said elongated member for coupling the steering wheel of the vehicle,

access locking means having secured and unsecured positions and also being disposed on the second end of the elongated member for securing the locking mechanism in place, and

illumination means for signalling presence of said locking mechanism with said motor vehicle, said illumination means including a battery, a plurality of lighting elements disposed on said locking mechanism and powered by said source of power for visually indicating the profile of said locking mechanism, condition responsive means for sensing engagement of said locking mechanism with said steering wheel and for activating said source of power to energize said lighting elements, and a photodetector for enabling said battery to power said lighting elements in low light conditions.
