Abstract
On a motorized vehicle with handlebars and handlebar mounted levers, a device includes a collar or clamp on which a thumb lever and catch slide in a groove to a desired position and are restrained by a notch, detent, slot, or other disruption in the groove to retain a handlebar lever in a desired position. Preferably, the thumb and catch are biased toward a disengaged position by a spring, by gravity, or by electro mechanical means. Spacers, additions, and handlebar extensions can all be provided with the device to allow for installation on a variety of handlebar sizes. In another embodiment, the thumb lever pivots about an axis generally perpendicular from the handlebar axis between a disengaged positon where the catch is clear from the clutch or brake lever and an engaged position where the catch engages the clutch or brake lever and holds it in a retracted position.
