Abstract:
1. An assembly for selectively locking the angular position of a biased throttle grip mounted on an end of a handlebar to control engine speed, the assembly comprising: a first member having a first face and adapted to be mounted on the end of the handlebar; a second member having a second face in close-spaced opposition to the first face and a third face spaced from the second face and in close-spaced opposition to an end face of the throttle grip when the first member is mounted on the end of the handlebar, the second member being mounted for rotation about an axis and for controlled shifting movement along the axis relative to the first member between a first position which corresponds to the unlocked mode of the assembly and a second position which corresponds to a locked mode of the assembly, wherein one of the first and second faces defines a reference surface and at least one depression of a first predetermined depth, each depression having bottom and side surfaces, one of the side surfaces being a ramped cam surface adjacent the bottom surface and tangentially intersecting the reference surface; and at least one cam follower mechanism including a follower disposed between the first and second faces and riding on its ramped cam surface to move the second member from the first position to the second position during rotation of the second member in a first direction about the axis and cause the third face of the second member to compress against the end face of the throttle grip to lock the second member and the throttle grip together to prevent slippage between the third and end faces.
