Rowing exercising apparatus

Abstract

A rowing exercising apparatus includes a frame, a seat member mounted slidably on the frame, a wheel assembly including a resistance flywheel and a transmission wheel cooperatively mounted on the frame, a pull cord connected to the transmission wheel and having a manual operation end, and a restoring unit including an elastic rope having a fixed end mounted to the frame and a moving end connected to the transmission wheel.

1 . A rowing exercising apparatus comprising: 
 a frame;    a seat member mounted slidably on said frame;    a wheel assembly including a resistance flywheel and a transmission wheel cooperatively mounted on said frame;    a pull cord connected to said transmission wheel and having a manual operation end; and    a restoring unit including an elastic rope having a fixed end mounted to said frame and a moving end connected to said transmission wheel.    
   
   
       2 . The rowing exercising apparatus as claimed in  claim 1 , wherein said frame includes an elongated bar having front and rear ends, and two foot plates mounted respectively on left and right sides of said elongated bar, said seat member being mounted on said elongated bar.  
   
   
       3 . The rowing exercising apparatus as claimed in  claim 2 , wherein said resistance flywheel is disposed on said elongated bar adjacent to said front end, said transmission wheel being disposed rearwardly of said resistance flywheel.  
   
   
       4 . The rowing exercising apparatus as claimed in  claim 3 , wherein said wheel assembly further includes a transmission belt extending over and interconnecting said flywheel and said transmission wheel, said pull cord being wound around said transmission wheel independently of said transmission belt.  
   
   
       5 . The rowing exercising apparatus as claimed in  claim 4 , wherein said transmission wheel has coaxially arranged first, second and third annular grooves, said first annular groove receiving said transmission belt therein, said second annular groove receiving said pull cord therein, said third annular groove receiving said elastic rope therein.  
   
   
       6 . The rowing exercising apparatus as claimed in  claim 4 , wherein said frame further includes an upright supporting unit which includes left and right upright supports extending upwardly on the left and right sides of said elongated bar, and a connecting portion connected to top ends of said left and right supports, said wheel assembly being mounted on said upright supports.  
   
   
       7 . The rowing exercising apparatus as claimed in  claim 4 , wherein said restoring unit further includes a first pulley mounted on said elongated bar proximate to said front end, and a second pulley mounted on said elongated bar and disposed rearwardly of said first pulley, said elastic rope passing over said first and second pulleys between said fixed end and said moving end.  
   
   
       8 . The rowing exercising apparatus as claimed in  claim 6 , further comprising a handle bar, said operation end of said pull cord being connected to said handle bar.  
   
   
       9 . The rowing exercising apparatus as claimed in claim  8 , wherein said wheel assembly further includes a guide roller mounted on said connecting portion, said pull cord passing over said guide roller between said transmission wheel and said handle bar.
