Abstract
A rotary actuator for a bicycle handbrake is characterized by a housing connected with a bicycle handlebar and an actuator rotatably connected with the housing. The actuator has a handle which extends radially from the axis of rotation of the actuator. A brake cable is connected with the actuator so that when the actuator is rotated in one direction, the cable is pulled to squeeze the brake calipers against the rim of a bicycle wheel, and when the actuator is rotated in the other direction, the cable is pushed to release the brake calipers. A releasable locking mechanism between the actuator and the housing is operable to lock the actuator in a brake release position and to release the actuator for rotation to apply the brake.
Claims13
Apparatus for displacing a bicycle brake cable to apply and release a bicycle brake, comprising
- (a) a housing mounted on a bicycle handlebar, said housing including a spindle;
- (b) an actuator mounted on said housing spindle, one end of the brake cable being connected with said actuator, said actuator including a handle which extends generally radially from the bicycle handlebar and having an axis of rotation generally parallel to the bicycle handlebar;
- (c) means for connecting said actuator with said spindle;
- and
- (d) means for releasably locking said actuator with respect to said housing, whereby when said actuator is rotated in a first direction with respect to said housing, said actuator pulls the brake cable to apply the bicycle brake, and when said actuator is rotated in a second direction with respect to said housing, said actuator pushes the brake cable to release the bicycle brake and said locking means fixes said actuator in a brake release portion.
