Abstract A spring drive and a spring drive scooter for use by an operator. The spring drive and spring drive scooter have a frame, a resilient member connected to the frame, a pedal, and a movement. The pedal is supported by the resilient member. The pedal is disposed to bear the operator. The pedal is capable, together with the operator, of oscillatory motion relative to the frame in response to at least roughly periodic impulses supplied to the pedal by the operator at a range of frequencies including a resonant frequency. The movement is connected to the frame and includes a final driven member. The movement is actuated by reciprocation of the pedal, the movement is capable of converting oscillatory motion of the pedal into circular motion of the final driven member.

A spring drive scooter for use by an operator, said spring drive scooter comprising a frame, said frame including a steering mechanism and one or more front wheels, a resilient member connected to said frame, a pedal supported by said resilient member, said pedal being disposed to bear said operator, said pedal, said operator, and said resilient member exhibiting oscillatory motion relative to said frame in response to at least roughly periodic impulses supplied to said pedal by said operator at a range of frequencies including a resonant frequency, and a movement connected to said frame, said movement being actuated by reciprocation of said pedal, said movement including a transmission actuated by said pedal and at least one final driven wheel actuated by said transmission, said transmission comprising a linear element operatively coupled to said pedal and a circular element operably coupled to said final driven wheel by means of an overrunning clutch, whereby said linear element is capable of turning said circular element during said vibration of said pedal.
