<p>A child's riding vehicle employing a unique and novel gear assembly and engagement structure includes a frame (12) having plural wheels, and a gear assembly (40) fixed on the frame which includes an output gear (54) non-rotatably connected to at least one of the vehicle's wheels. A motor (66) on the frame is mounted on an arm (68) which is movable between an engaged position (A) and a disengaged position (B), and a segment gear (62) mounted on the frame adjacent the gear assembly engages the motor's pinion (66a) and defines a path between the engaged and disengaged position. Unique and novel gear tooth profiles are employed in both the gear assembly and the engagement structure to prevent the same from jamming during transition between the engaged and disengaged positions and vice versa.</p> |
