Oblong Orbital Exercising Machine Having Adjustable and Extendable Trace of Movement

Abstract

An oblong orbital exercising machine includes a main frame, an upright mounted on the main frame, two swinging handles each pivotally connected with the upright, two mounting rods each mounted on the respective swinging handle, two adjusting members each adjustably mounted on the respective mounting rod, a cycle movement mechanism mounted on the main frame, two cranks mounted on the cycle movement mechanism, two links each pivotally connected with the respective adjusting member and the respective crank, two sliding members each slidably mounted on the respective link, two pedals each secured on the respective sliding member, and two driven levers each pivotally connected with the respective mounting rod and the respective sliding member. Thus, the pedals are moved relative to the links to lengthen the forward and backward pace of the user's feet, so that the user's legs are extended.

1 . An oblong orbital exercising machine, comprising:
 a main frame;   an upright mounted on a front portion of the main frame;   two swinging handles each pivotally connected with the upright;   two mounting rods each mounted on a respective one of the swinging handles and each provided with a plurality of adjusting holes;   two adjusting members each adjustably mounted on a respective one of the mounting rods;   a cycle movement mechanism mounted on a rear portion of the main frame;   two cranks mounted on two opposite sides of the cycle movement mechanism;   two links each having a first end pivotally connected with a respective one of the adjusting members and a second end pivotally connected with a respective one of the cranks;   two sliding members each slidably mounted on a respective one of the links;   two pedals each secured on a respective one of the sliding members; and   two driven levers each having a first end pivotally connected with a respective one of the mounting rods and a second end pivotally connected with a respective one of the sliding members.   
     
     
         2 . The oblong orbital exercising machine of  claim 1 , wherein the two adjusting pins each mounted on a respective one of the adjusting members and each detachably locked in any one of the adjusting holes of a respective one of the mounting rods. 
     
     
         3 . The oblong orbital exercising machine of  claim 1 , wherein:
 the first end of each of the links is provided with an arcuate curved portion pivotally connected with the respective adjusting member; and   the arcuate curved portion of each of the links extends upward.   
     
     
         4 . The oblong orbital exercising machine of  claim 1 , wherein:
 each of the links has two opposite sides each provided with a guide track; and   each of the sliding members has two opposite sides each provided with at least one roller rotatably mounted in the respective guide track of the respective link.   
     
     
         5 . The oblong orbital exercising machine of  claim 1 , wherein each of the adjusting members is movable upward and downward on the respective mounting rod to drive and move the respective link, with each of the links being located at different positions and angles to change the movement traces of each of the links. 
     
     
         6 . The oblong orbital exercising machine of  claim 1 , wherein each of the mounting rods has an upper end connected with a lower end of the respective swinging handle and a lower end pivotally connected with the first end of the respective driven lever. 
     
     
         7 . The oblong orbital exercising machine of  claim 1 , wherein each of the mounting rods is pivotally connected with a respective one of the links by a respective one of the adjusting members. 
     
     
         8 . The oblong orbital exercising machine of  claim 1 , wherein:
 each of the cranks has a first end connected with the cycle movement mechanism and a second end connected with the respective link;   the swinging handles are located at two opposite sides of the upright; and   each of the links is moved by swinging action of the respective swinging handle and by rotation of the cycle movement mechanism.
