Exercise machine

Abstract

An exercise machine has a main body, two operating rods, a resistance unit, and two pedaling members. The main body has a base and a standing pole, two sides of the standing pole are both respectively pivoted with a pivoting joint, each pivoting joint having a through aperture for accepting one of the operating rods, a supporting frame installed between the standing pole and the base. Each operating rod is connected to the pivoting joints. The resistance unit has a driving wheel, a passive wheel, and a transmission member coupling the driving wheel to the passive wheel. Each pedaling member comprises a pedal pole, a first connecting rod, and a second connecting rod, the pedal pole is attached to a lower end of one of the operating rods and has a pedal at one end and another end pivoted onto the main body via a pivoting connector.

What is claimed is: 
     
         1 . An exercise machine, comprising: a main body, two operating rods, a resistance unit, and two pedaling members, wherein:
 the main body comprises a base and a standing pole, two sides of the standing pole are both respectively pivoted with a pivoting joint, each pivoting joint having a through aperture for accepting one of the operating rods, a supporting frame installed between the standing pole and the base;   each operating rod comprises a handle and is inserted in one of the through apertures to be connected to one of the pivoting joints, a lower end of each operating rod being attached to one of the pedaling members;   the resistance unit comprises a driving wheel, a passive wheel, and a transmission member coupling the driving wheel to the passive wheel, the driving wheel and the passive wheel respectively mounted in the main body via a driving wheel axis and a passive wheel axis, and a flywheel is coaxially installed with the passive wheel; wherein the driving wheel drives the flywheel to rotate via the transmission member and the passive wheel; and wherein the resistance unit further comprises a magnetic member pivoted on the main body configured to passively generate different resistances to the flywheel and the pedaling member; and   each pedaling member comprises a pedal pole, a first connecting rod, and a second connecting rod, the pedal pole attached to a lower end of one of the operating rods and has a pedal at one end and another end pivoted onto the main body via a pivoting connector, and the first connecting rod is installed between the pedal pole and the second connecting rod; wherein a free end of the second connecting rod is secured onto the driving wheel axis, such that the pedals of the two pedaling members are configured to drive the driving wheel via the first connecting rod and the second connecting rod.   
     
     
         2 . The exercise machine as claimed in  claim 1 , wherein the base has an H-shaped structure. 
     
     
         3 . The exercise machine as claimed in  claim 1 , wherein the main body further comprises two housings for covering the resistance unit. 
     
     
         4 . The exercise machine as claimed in  claim 1 , wherein a horizontal rod is placed and secured between the pivoting joint and the standing pole to connect the pivoting joint to the standing pole. 
     
     
         5 . The exercise machine as claimed in  claim 1 , wherein the standing pole further comprises an armrest and a control panel. 
     
     
         6 . The exercise machine as claimed in  claim 1 , wherein a length of each operating rod is adjustable. 
     
     
         7 . The exercise machine as claimed in  claim 1 , wherein the transmission member comprises a belt and an idler for adjusting a tightness of the belt. 
     
     
         8 . The exercise machine as claimed in  claim 1 , wherein the driving wheel axis and the passive wheel axis are respectively installed on the base and the supporting frame. 
     
     
         9 . The exercise machine as claimed in  claim 1 , wherein for each pedaling member, the pedal pole, the first connecting rod and the second connecting rod are connected among each other such that the first connecting rod is configured to rotate at a middle section of the pedal pole.
