ABSTRACT:
A control lever for motorcycle handlebars and the like has a dislocating pivot. A cable connected to the lever transmits a controlling force to a brake, clutch, or other machine. The pivot is a two-pronged fork element and a central element pivotally connected at a pair of joints, one joint for each prong of the fork element. A joint is a cylindrical rod with a hemispherical or other shaped end, and a socket with a cavity shape suitable to the rod end. A spring pushes a rod into engagement within a socket. A lip partially around the opening of the cavity defines the range of allowable twisting motion of the lever arm. When the lever is forced out of the direction of its normal motion, the pivot elements dislocate, preventing damage to the lever. The force required for dislocation depends on the spring bias against the rod, the shape of rod end, and the depth of the socket cavity.
