Slidable treadle of treading machine

Abstract

A slidable treadle of a treading machine comprises a seat having two supporting rods; each of two sides of the supporting rod 12 has a damper for providing a resisting force to the treadle as the treadle is treaded; two treadles pivotally installed to two sides of the seat; each treadle having a main rod portion and a sub-rod portion for pivotally installing to the seat; one end of the main rod portion being pivotally installed to the treadle and another end thereof being pivotally installed to the seat; one end of the sub-rod portion being pivotally installed to a middle section of a respective one of the two treadles and another end thereof being pivotally installed to the seat. Using above structure, the treadles can move upwards, downwards, forwards and rearwards.

1 . A slidable treadle of a treading machine comprising: 
 a seat having two supporting rods;    each of two sides of the supporting rod having a damper for providing a resisting force to the treadle as the treadle is treaded,    two treadles pivotally installed to two sides of the seat; each treadle having a main rod portion and a sub-rod portion for pivotally installing to the seat; one end of the main rod portion being pivotally installed to the treadle and another end thereof being pivotally installed to the seat; one end of the sub-rod portion being pivotally installed to a middle section of a respective one of the two treadles and another end thereof being pivotally installed to the seat; and    wherein using above structure, the treadles moves upwards, downwards, forwards and rearwards.    
     
     
         2 . The slidable treadle of a treading machine as claimed in  claim 1 , wherein the damper is an oil pressure rod.  
     
     
         3 . The slidable treadle of a treading machine as claimed in  claim 1 , wherein the end of the main rod portion is pivotally installed to the front end of the treadle and another end thereof is pivotally installed to a front end of the seat; the end of the sub-rod portion is pivotally installed to the middle section of the treadle and another end thereof is pivotally installed to a middle end of the seat.  
     
     
         4 . The slidable treadle of a treading machine as claimed in  claim 1 , wherein one end of the damper is pivotally installed to one end of the seat and another end of the damper is pivotally installed to the supporting rod; 
 when the treadle is treaded, the sub-rod portion will provide resisting forces to the damper so as to compress the damper.    
     
     
         5 . The slidable treadle of a treading machine as claimed in  claim 1 , wherein a linkage is pivoted to a front end of the seat; the linkage is interacted with the main rod portion so that when one treadle is treaded, another treadle will restore to the original position.  
     
     
         6 . The slidable treadle of a treading machine as claimed in  claim 1 , wherein a head extends from one end of the seat and the head is installed with a handle.  
     
     
         7 . The slidable treadle of a treading machine as claimed in  claim 1 , wherein the seat has a left supporter and a right supporter at a front end thereof; a rear end of the seat has a supporting rod for stabling the seat not to vibrate or turn over; a cylindrical head extends from the left supporter and the right supporter; a display is embedded into the head for displaying exercise data.
