Abstract

A bicycle lock and alarm apparatus for use as a preventive or deterrent device in controlling bicycle thievery. A continuous cable adapted to extend through the bicycle wheels and also about the bicycle frame to immobilize the wheels and locking means to join the ends of the cable to form a loop. An electrical circuit including an electrical conductor running through the length of the cable and responsive to interruption of the conductor for activating an alarm.

Claims

1. A bicycle lock and alarm apparatus adapted to mount on the framework of a bicycle to immobilize the wheels and provide an alarm in the event the lock is forced comprising a lock-alarm case capable of passing sound through its walls, a bolt receiving member having a bolt guide, means to join said bolt receiving member together with said lock-alarm case, an electrical circuit mounted in said lock-alarm case, a buzzer-alarm connected to said circuit mounted within said case, an electrical energy source connected to said circuit mounted within said case, locking means mounted in said case, a latch attached to said locking means, a cable secured at one end within said case, a continuous conductor initiating and terminating within said lock alarm case extending throughout the length of said cable connected to said circuit, and a bolt secured to the free end of said cable formed to be engaged by said latch when inserted into said bolt guide, said circuit operating to activate said alarm when said conductor is interrupted.

2. In a bicycle lock and alarm apparatus for mounting on a bicycle having a framework, a bolt receiving member adapted to mount on a portion of the framework, a bolt guide having walls extending through the bolt receiving member and having a slot in one wall extending lengthwise of the guide, a mounting face on the bolt receiving member having a pattern of holes to accept fasteners, a mounting plate having a bolt hole of substantially the same dimension as the inside of the bolt guide and aligned with the guide and having a slot extending in a direction between the top and bottom of the plate aligned with the center line of the bolt hole and having a hole pattern for passing fasteners matching the pattern on the face of the bolt receiving member for attaching the plate to the bolt receiving member in a manner surrounding the framework and fixed thereto, top and bottom case guides substantially parallel to each other and formed along the top and bottom of the mounting plate, a lock-alarm case having a mounting face on one side and a plurality of holes on another side, flanges at the top and bottom of the mounting face on the lock-alarm case formed to mate with the top and bottom case guides, a buzzer-alarm mounted on the interior of the lock-alarm case next to the plurality of holes to allow audible noise to pass to the exterior of the case, locking means mounted to rotate in the lock-alarm case, a spring loaded latch attached to the locking means so as to extend through the mounting plate slot when the flanges on the case are fully engaged by the gUides on the mounting plate, a cable secured at one end to the interior of the lock-alarm case of sufficient length to pass through the framework and both wheels of the bicycle, an electrical circuit connected to the buzzer-alarm, a continuous electrical conductor connected to the electrical circuit and extending through the length of the cable, a source of electrical power connected to the circuit, and a bolt secured to the free end of the cable and adapted to fit in the bolt guide, the electrical circuit operating to activate the buzzer-alarm when the continuous electrical conductor is interrupted.
