Stepping exerciser

Abstract

A stepping exerciser includes a base having an inclined pivot axle perpendicular to an inclined plane inclined relative to the base, a pivotal supporting device attached to the inclined pivot axle of the base and movable in a plane parallel to the inclined plane, and two foot pedals pivotally attached to the pivotal supporting device and arranged to allow the foot pedals to be stepped downwardly by a user, and the foot pedals may be moved downwardly and rearwardly and upwardly and forwardly when the foot pedals are stepped by the user to simulate ladder climbing exercises. An arm is pivotally attached to the inclined pivot axle of the base for pivotally supporting the foot pedals.

1 . A stepping exerciser comprising:
 a base including an inclined pivot axle extended rearwardly and upwardly therefrom and perpendicular to an inclined plane inclined relative to said base,   a pivotal supporting device attached to said inclined pivot axle of said base and movable in a plane parallel to said inclined plane, and   two foot pedals pivotally attached to said pivotal supporting device and arranged to allow said foot pedals to be stepped downwardly by a user, and   said foot pedals being movable downwardly and rearwardly and upwardly and forwardly when said foot pedals are stepped by the user to simulate ladder climbing exercises.   
     
     
         2 . The stepping exerciser as claimed in  claim 1 , wherein said pivotal supporting device includes an arm having a middle portion pivotally attached to said inclined pivot axle of said base and having two end portions pivotally coupled to said foot pedals respectively. 
     
     
         3 . The stepping exerciser as claimed in  claim 2 , wherein said foot pedals each pivotally attach to said end portions of said arm with a pivot shaft, and each includes two bars of different lengths extended therefrom and pivotally attached to said pivot shafts respectively for horizontally supporting said foot pedals which are parallel to said base. 
     
     
         4 . The stepping exerciser as claimed in  claim 2 , wherein said pivotal supporting device includes two links pivotally coupled between said foot pedals and said base for forming a parallelogrammic structure and for stably supporting said foot pedals to said arm. 
     
     
         5 . The stepping exerciser as claimed in  claim 1  further comprising a resistive device disposed between said foot pedals and said base, to provide a resistive force against said foot pedals. 
     
     
         6 . The stepping exerciser as claimed in  claim 1  further comprising a resistive device disposed between said pivotal supporting device and said base, to provide a resistive force against said foot pedals. 
     
     
         7 . The stepping exerciser as claimed in  claim 6 , wherein said pivotal supporting device includes an arm having a middle portion pivotally attached to said inclined pivot axle of said base, and said resistive device is coupled to said arm. 
     
     
         8 . The stepping exerciser as claimed in  claim 7 , wherein said pivotal supporting device includes a fastening plate attached to said base and engaged with said arm and said resistive device to stably retain said arm and said resistive device to said base. 
     
     
         9 . The stepping exerciser as claimed in  claim 1 , wherein said base includes a post extended upwardly and forwardly therefrom along said inclined plane, said pivot axle is extended upwardly and rearwardly from said post.
