ABSTRACT:
A throttle control assembly includes a throttle screw for retaining a hand grip throttle control in a desired position, and a thumb grip extension device removably attached to the head of the throttle screw to facilitate turning the screw. The thumb grip extension device includes a disc-shaped base, a plurality of detent structures extending above an upper surface of the base, and a handle protruding radially outwardly from one of the detent structures. The detent structures each have a convex outer surface with a curvature that generally corresponds to the outer periphery of the base, a convex inner surface, and a detention ridge protruding from and extending across the convex inner surface at a location spaced from the upper surface of the base. The detent structures are resiliently movable outwardly relative to each other to allow the device to be installed and retained on the head of the throttle screw.
