Patent ID: 7458443

Claim:
A braking mechanism for actuating a supplemental brake associated with a bicycle, said braking mechanism being used in association with a pedal-actuated brake for actuating a rear wheel brake, the rear wheel brake being a coaster brake and including at least a cone having a key and a threaded axle defining a keyway, the threaded axle being rotatable relative to the key, the bicycle including a frame having a rear fork for mounting a rear wheel, the frame including an upper frame member and a lower frame member, said apparatus comprising: a brake lever arm defining a proximal end and a distal end, said proximal end being adapted to engage the brake cone key, said distal end being adapted to slidably mount on said bicycle frame to allow said brake lever arm to rotate through a selected degree about an axis of the threaded axle, said brake lever arm defining an indexing pin fixed to and extending orthogonally away from said brake lever arm; a yoke for releasably securing an end of a conventional brake cable, the conventional brake cable being secured at an opposite end to the supplemental brake; and a limiter cam defining a central opening having a tab configured to be received within the threaded axle keyway, said limiter cam defining a plurality of radially spaced-apart teeth, said brake lever arm indexing pin being received between a pair of said plurality of radially spaced-apart teeth, whereby said brake lever arm is permitted to rotate in each direction with respect to said limiter cam through a selected angle.
