First Claim
1. An athletic apparatus comprising:
- a frame including an axle rod,two rotary wheels rotatably installed on said frame,a pair of tracks disposed on said frame and tilted relative to said frame for a predetermined angle, and each track including a curved and non-linear structure,a pair of pedal mechanisms slidably attached to said tracks and movable along said tracks respectively, and each including a pedal for supporting a user'"'"'s feet,a pair of rocker arm mechanisms each including a rocker arm having an upper end pivotally attached to said axle rod of said frame and having a lower end pivotally coupled to said pedal mechanisms respectively,a first transmitting mechanism including a pulley attached to said frame and located below upper ends of said tracks, and a steel rope engaged with said pulley and having two ends coupled to said pedal mechanisms respectively for pivotally coupling said pedal mechanisms together and for guiding said pedal mechanisms to move up and down along said tracks respectively,a second transmitting mechanism including two linking belts each having a first end coupled to said lower ends of said rocker arms respectively and each having a second end coupled to an elastic belt, and the elastic belt being engaged with said rotary wheels of said frame for allowing said lower ends of said rocker arms to be coupled together with said linking belts and said elastic belt,a shaft rod installed on said frame,a belt wheel installed on said shaft rod,two gear wheels installed on said shaft rod with unidirectional bearings and engaged with said linking belts respectively.
