Abstract
A rotating brake actuator for a bicycle in which a rotation of a handle grip tensions a cable connected to a friction brake of the bicycle. The actuator includes a rotatable handle assembly which may be secured to a handlebar of the bicycle by an expandable end cap. A pulley is coupled to the handle assembly and eccentrically supports an end of the cable such that a rotation of the handle grip tensions the cable to apply the brake. The actuator includes a digit operated release assembly that prevents a rotation of the handle assembly to preclude an unintentional application of the brake.
Claims5
A new rotating brake actuator for use with a bicycle having a cable operatively coupled to at least one friction brake, said actuator comprising:
- a base sleeve positionable upon an end of a handlebar of said bicycle;
- a handle grip concentrically positioned upon and spaced from said base sleeve and rotatably supported relative thereto by at least one bearing;
- said handle grip and said base sleeve having spacing therebetween;
- a pulley mechanically coupled to said handle grip such that a rotation of said handle grip proportionally rotates said pulley, said pulley being operable to receive and support an end of said cable such that said at least one friction brake may be operated by a manual rotation of said handle grip;
- and;
- a release assembly means operable to selectively preclude a rotation of said handle grip with respect to said base sleeve, said release assembly means comprising a release button movably mounted in said handle grip and projecting into said spacing and selectively operated by a user to allow a rotation of said handle grip with respect to said base sleeve, said release assembly means further including a projection extending into said spacing and fixed to said base sleeve for selective engagement with said release button.
