Dual function handlebar mounted actuator
First Claim
1. A dual function handlebar mounted actuator comprising means for operating a brake function and means for operating a clutch function, a single hand operated lever for contact by a user, the lever being arranged to separately activate at least one of said brake function operating means and said clutch function operating means, wherein said brake function operating means and said clutch function operating means are linked so that a combined brake and clutch function can be activated, wherein the lever is arranged so that movement in a first direction activates said clutch function operating means and further movement of the lever in the first direction to an activation point activates said brake function operating means, and wherein activation of the lever in a second direction activates said brake function and continued activation of the lever in said second direction activates said clutch function.

Abstract
A dual function handlebar mounted actuator has first and second function operating devices arranged for activation by movement of a hand operated lever arrangement. The first and second functions operating devices are linked so that a combined first and second function can be activated and the first and second functions are a clutch and a brake function. The actuator has a lever movable between a first and a second position, and a master cylinder having a piston with the lever moving towards the second position to drive a piston from its initial position thereby increasing pressure in the master cylinder. By releasing the lever the pressure within the master cylinder is arranged to return the piston towards its initial position and the piston being returned fully to the initial position upon movement of the lever to the first position.

2. A dual function handlebar mounted actuator comprising means for operating a brake function and means for operating a clutch function, a single hand operated lever for contact by a user, the lever being arranged to separately activate at least one of said brake function operating means and said clutch function operating means, wherein said brake function operating means and said clutch function operating means are linked so that a combined brake and clutch function can be activated;
- and means for sensing an R.P.M. of an associated engine, wherein the lever is arranged so that when the sensed R.P.M. is above a first predetermined value, movement of a first portion of the lever will result in operation of said brake function, and wherein when the sensed R.P.M. is below the first predetermined value movement of the first portion of the lever will result in operation of said brake function and said clutch function so as to prevent stalling of the engine.

4. A dual function handlebar mounted actuator comprising means for operating a brake function and means for operating a clutch function, a single hand operated lever for contact by a user, the lever being arranged to separately activate at least one of said brake function operating means and said clutch function operating means, wherein said brake function operating means and said clutch function operating means are linked so that a combined brake and clutch function can be activated, and wherein movement of the lever in a first direction operates said clutch function, movement of the lever in a second direction operates said brake function, the dual function handlebar further includes a combined function means arranged so that when the lever is moved in said first direction to an initiation point said combined function means causes the lever to also move in said second direction so that both said clutch function and said brake function are operated.
