Abstract
A dual function handgrip control, permits independent operation of two functions from a single handgrip, such as both the throttle and front brake mechanism of a motorcycle, by manipulation of a single handgrip control. For motorcycle use, the handgrip control includes a handgrip which is rotatably mounted on the handlebar and connected to the throttle mechanism of the motorcycle, through a lost motion connection and to the brake operating lever. Separate control of the throttle and brake mechanisms is thereby accomplished.
Claims7
A dual control handgrip device for individually operating a first and a second device, comprising:
- a handgrip, including a gripping portion:
- first control means for operating an associated device in response to rotary mechanical forces;
- mounting means operable to rotatably mount said handgrip on said first control means;
- said mounting means comprising a first portion secured to said first control means and operable to rotably drive said first control means, and a second portion mounted on said handgrip;
- said first and second portions being rotatable with respect to each other;
- and a lost motion connection connecting said first and second portions for concurrent rotation to rotably drive said first control means when said first and second portions are moved in a first predetermined direction, and permitting relative movement therebetween when said first and second portions are rotated in a second predetermined direction, opposite said first predetermined direction;
- and
- second control means secured to said handgrip and operable to control a second device in response to the relative rotation of said first and second portions in said second predetermined direction;
- whereby said first and second control means are individually operated.
A motorcycle hand control for operation of both the handlebar mounted throttle and brake mechanisms of a motorcycle, by manipulation of a single handgrip control, comprising:
- a handgrip, including a gripping portion;
- mounting means operable to rotatably mount said handgrip on the throttle mechanism, said mounting means comprising a first portion operable to be secured to the throttle mechanism;
- a second portion mounted on said handgrip, said first and second portions being rotatable with respect to each other, and a lost motion connection engaging said first and second portions for concurrent rotation, when said first and second portions are moved in a first predetermined direction, and permitting relative movement therebetween when said first and second portions are rotated in a second predetermined direction, opposite said first predetermined direction;
- and
- a brake operating device secured to said handgrip and operable to actuate the brake mechanism of the motorcycle in response to the relative rotation of said first and second portions in said second predetermined direction.
