Fitness machine

Abstract

A fitness machine includes a framework, a swinging device pivotally connected with the framework, a transmission mechanism having a driving device and a driven device respectively movably connected with the swinging device, and an operating device connected with the driven device. When the swinging device is turned, the driving device drives the driven device to rotate to further turn the operating device.

1 . A fitness machine for comprising: 
 a framework;    a swinging device having a first rod member pivoted to said framework and a second rod member coupled to said first member;    a transmission mechanism having a driving device and a driven device respectively movably mounted to said first and second members of said swinging device, whereby said driving device drives said driven device to rotate while said swinging device is rotated relatively to said framework; and    an operating device coupled to said driven device of said transmission mechanism for rotation by said driven device.    
   
   
       2 . The fitness machine as defined in  claim 1 , wherein said driving device comprises a main tube sleeved onto said first member of said swinging device, a first bevel gear fixedly provided at a first end of said main tube and coupled to said framework, and a second bevel gear fixedly provided at a second end of said main tube; said driven device comprises an auxiliary tube sleeved onto said second member of said swinging device, a first bevel gear fixedly provided at a first end of said auxiliary tube and meshed with the second bevel gear of said driving device, and a second bevel gear fixedly provided at a second end of said auxiliary tube.  
   
   
       3 . The fitness machine as defined in  claim 2 , wherein said framework comprises a locating block, and a bevel gear formed from a side of said locating block and meshed with said first bevel gear of said driving device.  
   
   
       4 . The fitness machine as defined in  claim 1 , wherein said operating device comprises a grip, and a bevel gear provided at a bottom side of said grip and meshed with the second bevel gear of said driven device.  
   
   
       5 . The fitness machine as defined in  claim 4 , wherein said operating device further comprises a link, said link having a first eyelet fixedly provided at a first end thereof and coupled to said main tube, a second eyelet fixedly provided at a second end thereof and coupled to said grip, and a bottom coupling ring fixedly provided at a bottom side thereof and coupled to said auxiliary tube.  
   
   
       6 . The fitness machine as defined in  claim 1 , wherein said framework comprises a base having two pairs of diagonal corners, a first frame extending upwards from said one pair of the diagonal corners of said base, a second frame extending upwards from the other pair of the two diagonal corners of said base, said first and second frames respectively having top sides crossing each other over said base.  
   
   
       7 . The fitness machine as defined in  claim 6 , wherein said first frame of said framework further comprises a crossbar for holding by the user.  
   
   
       8 . The fitness machine as defined in  claim 6 , wherein said second frame of said framework further comprises a sleeve and a locating block, said sleeve being movably mounted to said second frame, said locating block being disposed on said sleeve and meshed with said driving device of said transmission mechanism.
