Abstract:
1. An oscillated fitness bicycle structure, comprising: a base, for installing the following components; and a handle support rod and a saddle support rod, integrally coupled with each other, and having a handle disposed at a front end and a saddle disposed at a rear end; characterized in that said structure further comprises: an oscillation rod, with an end pivotally coupled to a front end of said base by an axle pin for back-and-forth switching movements, and another end pivotally coupled with said handle support rod and the bottom of said saddle support rod integrated with each other by an axle pin; a first driving apparatus, having a shaft module with a shaft fixed at a rear end of said base by an axle base and a driving wheel installed at an end of said shaft of said shaft module; a first driving rod, with an end vertically and pivotally integrated with said handle support rod and along a side of the rear end of said saddle support rod, and another end rotably fixed at an eccentric portion at an end of a said shaft of said shaft module of said first driving apparatus by a positioning bolt for pushing or pulling said handle support rod and the rear end of said saddle support rod as said shaft rotates; a second driving rod, with an end pivotally coupled sideways with said handle support rod and another side of a rear end of said saddle support rod, and another end freely and rotably fixed at an eccentric portion at another end of said shaft of said first driving apparatus by a positioning bolt, for pushing or pulling said handle support rod and along another side of the rear of said saddle support rod as said shaft rotates; a second driving apparatus, having a weight wheel, freely and rotably installed at said base, a driving wheel installed with said weight wheel together at a same shaft, a driving belt surrounded between said driving wheel of said second driving apparatus and said driving wheel of said first driving apparatus, so as to link said weight wheel and said driving wheel of said first driving apparatus; a resilient element, installed between said handle support rod and said saddle support rod with said base, for providing said handle support rod and the rear end of said saddle support rod with an upward bouncing effect; and a pedal rod, installed on both sides of said saddle support rod for both legs to pedal said pedal rod; thereby, after an exerciser sits on said saddle and places both legs on said pedal rod, the body weight of said exerciser together with the forces produced by said exerciser's hip, waist, hands or legs are applied onto said handle support rod and said saddle support rod, such that said two driving rods operate together with said weight wheel of said second driving apparatus to transmit a driving force to said shaft of said first driving apparatus, and said two driving rods respectively push and pull said handle support rod and both sides of said saddle support rod during an eccentric circumferential movement, so that said handle support rod and said saddle support rod can perform leaping back-and forth, up-and-down, and sideways oscillations.
