Stepper exerciser

Abstract

A stepper exerciser comprises a swinging base, a moveable base and a foot-stepping connecting rod, between the matching cases on the swinging base; there is a moveable base, to which a foot-stepping connecting rod is connected. A foot-stepping connecting rod mechanism, comprising an axle between the two side plates of the moveable base, a connecting rod extending out of the axle, a supporting base on each end of the connecting rod, a paddle on each supporting base, and the swinging base to allow simultaneous motion, and between the cases of the swinging base there is a recovery element, which can set the paddle in a non-swinging state when no action is exerted on the paddle and the swinging base returns to its non-swinging state; therefore, a lever mechanism is formed during the up-and-down of the paddles on the moveable base with the curved cases of the swinging base.

1 . A stepper exerciser, mainly composed of: 
 a swinging base, including two matching cases in curved shape with bottom sticking out as a flange and several locking holes on top, which allow a blot to pass through and be capped with a nut to combine the two cases into a swinging base;    a moveable base, including two side plates with rollers, with an axle hole on each side plate for the bolt to pass through and combine the two cases of the swinging base, allowing the moveable base positioned between the two cases of the swinging base;    a foot-stepping connecting rod mechanism, comprising an axle between the two side plates of the moveable base, a connecting rod extending out of the axle, a supporting base on each end of the connecting rod, a paddle on each supporting base, with bolts to connect the supporting base and the swinging base to allow simultaneous motion;    through this, a lever mechanism is formed during the up-and-down motion of the paddles on the moveable base with the curved cases of the swinging base, so the user can use body weight on the paddle to conduct balance training, up-and-down stepping exercise and shifting action exercise.    
     
     
         2 . The stepper exerciser as claimed in  claim 1 , the two rods on the axle can form the connecting rod.  
     
     
         3 . The stepper exerciser as claimed in  claim 1 , one rod on the axle can form the connecting rod.  
     
     
         4 . The stepper exerciser as claimed in  claim 1 , an axle hole on the supporting base of the connecting rod mechanism allows the bolt of the cases of the swinging base to pass through and results in simultaneous motion between the connecting rod and the swinging base.  
     
     
         5 . The stepper exerciser as claimed in  claim 1 , there is a vertical through hole on the supporting base of the connecting rod mechanism to allow the placement of a paddle inside.  
     
     
         6 . The stepper exerciser as claimed in  claim 1 , there is an extension plate on the top edge of the supporting base of the connection rod mechanism and the extension plate has a locking hole.  
     
     
         7 . The stepper exerciser as claimed in  claim 1 , the paddle is situated in the connecting rod mechanism through an axle inserted into a hole.  
     
     
         8 . The stepper exerciser as claimed in  claim 1 , on the bottom edge of the paddle corresponding to the locking hole on the extension plate there is a stopper column, which prevents paddles from rotating.  
     
     
         9 . The stepper exerciser as claimed in  claim 1 , the axle of the paddle of the connecting rod mechanism has a locking hole for a bolt to pass from the axle hole bottom for connection and there is a spring between the nut and the axle hole for cushion purpose. Thus, when the axle of the paddle is in the axle hole, it still can be pulled up and quickly engage into a locking action. So the paddle can rotate freely without jumping off. The mechanism has a simple design of paddle positioning and rotation adjustment.  
     
     
         10 . The stepper exerciser as claimed in  claim 1 , between the cases of the swinging base there is a recovery element, which can be an elastic element, hydraulic cylinder . . . etc., retractable element to set the paddle in a non-swinging state when no action is exerted on the paddle and the swinging base returns to its non-swinging state.
