Abstract:
A scooter comprising in combination:a central tubular chassis having a front portion and rear portion;a platform supported on the central tubular chassis between the front portion and the rear portion;a front steered wheel with a peripheral ground contacting surface attached to the tubular chassis at the front portion;a rear driven wheel with a peripheral ground contacting surface attached to the tubular chassis at the rear portion;a cantilevered support permitting rotation of the rear driven wheel;an engine pivotally mounted to the tubular chassis on a pivot arm, the pivot arm attached to the tubular chassis at a pivot point offset from the axis of rotation of the driven wheel;a protruding driving shaft driven by the engine overlying the driven wheel for moving into and out of contact with the ground contact surface of the driven wheel;the pivot point of the pivot arm offset relative to a line between the point of contact of the protruding driving shaft and the center of driven wheel rotation in the direction of driven wheel rotation at the protruding driving shaft whereby the reactive vector component acting on the driving protruding shaft urges the driving protruding shaft into contact with the ground contact surface of the driven wheel;a cable control lever; anda cable connected to the cable control lever at one end and attached to the engine at a position spaced apart from the pivot at the opposite end to adjustably limit pivotal movement of the engine on the pivot arm whereby controlling movement of the protruding driving shaft into and out of contact with the ground contact surface of the driven wheel.
