Transmission and drive-train systems of 2 wheel, 3 wheel and 4 weel exercise scooters incorporating (1) seesaw foot pedal and (2) left & right step foot pedals

Abstract

Three types of free-wheel drive-train systems incorporated under the pedal of skate scooters that enables forward propulsion of the scooters through repetitive up and down foot motions. The drive-train systems of 2 wheel, 3 wheel and 4 wheel exercise step scooters consists of (1) Single Seesaw foot pedal with center pivot, (2) Rear-stepping, Right and Left foot pedals with Front pivot, (3) Front-stepping, Right and Left foot pedals with Rear pivot.

What I claim as my invention is: the 3 types of free-wheel drive-train systems incorporated under the pedal of skate scooters that enables forward propulsion of the scooters through repetitive up and down foot motions:  
     
         1 . First type—the drive-train mechanism of the Seesaw pedal skate scooter, in accordance with the attached documents and graphs, consist of the following unique features: Seesaw pedal is installed on the skate scooter and the force generated by the repetitive up and down motion of the pedal is transferred to the rear wheels by the integral drive-train mechanism  
     
     
         2 . Second type—the drive-train mechanism of the Front pivot rear-stepping skate scooter, in accordance with the attached documents and graphs, consist of the following unique features: 
 L/H and R/H foot pedals are installed on the skate scooter and the force generated by the stepping motion of the pedal is transferred to the rear wheels by the integral drive-train system.  
 
     
     
         3 . Third type—the drive-train mechanism of the Rear pivot Front-stepping skate scooter, in accordance with the attached documents and graphs, consist of the following unique features: 
 L/H and R/H foot pedals are installed on the skate scooter and the force generated by the stepping motion of the pedal is transferred to the rear wheels by the integral drive-train system.
