Climbing exercise machine

Abstract

A climbing exercise machine includes a beam supported on two columns supported on a base. Two handles are movably supported on the columns, respectively. The handles are movable in opposite directions. Two treads are movably supported on the columns, respectively. The treads are movable in opposite directions. An input axle is supported on the columns. The input axle is rotated as the handles and the treads are moved. A transmission case connects the input axle to an output axle. A disc is connected to the output axle. A frame is connected to the beam. A resistance element is supported on the frame. The resistance element includes a magnet. The resistance element is movable relative to the disc to adjust magnetism exerted on the disc by the magnets.

1 . A climbing exercise machine comprising:
 a base;   two columns supported on the base;   a beam supported on the columns;   two handles movably supported on the columns, respectively, wherein the handles are movable in opposite directions;   two treads movably supported on the columns, respectively, wherein the treads are movable in opposite directions;   an input axle supported on the columns, wherein the input axle is rotated when the handles and the treads are moved;   an output axle connected to the input axle;   a transmission case for connecting the input axle to the output axle:
 a disc connected to the output axle; 
 a frame connected to the beam; and 
 a resistance element supported on the frame, wherein the resistance element comprises a magnet, wherein the resistance element is movable relative to the disc to adjust magnetism exerted on the disc by the magnets. 
   
     
     
         2 . The climbing exercise machine according to  claim 1 , wherein the transmission case comprises an input gear supported on the input axle, an output gear supported on the output axle, and intermediate gears arranged between the input and output gears. 
     
     
         3 . The climbing exercise machine according to  claim 1 , further comprising an axle supported on the frame, wherein the resistance element comprises a lug supported on the axle, wherein the magnet is connected to the lug. 
     
     
         4 . The climbing exercise machine according to  claim 3 , further comprising a torque spring formed with two terminal sections in contact with the frame and the lug, respectively. 
     
     
         5 . The climbing exercise machine according to  claim 1 , further comprising a knob connected to the resistance element via at least one rope, wherein the knob is operable to move the resistance element relative to the disc. 
     
     
         6 . The climbing exercise machine according to  claim 5 , further comprising a processor electrically connected to the knob, wherein the processor detects the position of the resistance element relative to the disc via the knob and converts the position into an electronic signal. 
     
     
         7 . The climbing exercise machine according to  claim 1 , wherein on each of the columns, the handle and the tread are movable in opposite directions. 
     
     
         8 . A climbing exercise machine comprising:
 two columns;   a beam supported on the columns;   an input axle supported on the columns;   an output axle;   a transmission case for connecting the input axle to the output axle;   a disc supported on the output axle;   a resistance element comprising a magnet, wherein the resistance element is supported on the beam and movable relative to the disc; and
 a knob connected to the resistance element via at least one rope, wherein the knob is operable to move the resistance element relative to the disc. 
   
     
     
         9 . The climbing exercise machine according to  claim 8 , further comprising a processor electrically connected to the knob, wherein the processor detects the position of the resistance element relative to the disc via the knob and converts the position into an electronic signal. 
     
     
         10 . The climbing exercise machine according to  claim 8 , wherein on each of the columns, the handle and the tread are movable in opposite directions.
