Upper and lower body exerciser

Abstract

An exerciser includes two idle wheels rotatably supported on a base, two handles rotatably attached to a shaft of the base and coupled to one of the idle wheels with a coupling device, and two foot pedals rotatably attached to the base with a spindle and coupled to the other idle wheel, two electric generators coupled to the shaft and the spindle, and two magnetic brake devices for braking the idle wheels. The coupling device includes two sector gears attached to the handles, and two gear-and-pinions rotatably supported on a pivot pin, and two gears and two pinions rotatably attached to another pivot pin with unidirectional bearings, for continuously rotating the idle wheel.

1 . An exerciser comprising: 
 a base including a shaft supported thereon,    a seat cushion supported on said base, for supporting a user thereon,    two foot pedals rotatably attached to said base with cranks and a spindle, for being pedaled by the user,    a first idle wheel rotatably supported on said base and coupled to said spindle, for being driven by said spindle,    a first generator coupled to said spindle, for being driven by said spindle,    a first magnetic brake device disposed beside said first idle wheel, for braking said first idle wheel,    two handles rotatably attached to said shaft, for allowing said handles to be pushed and pulled by the user,    a second idle wheel rotatably supported on said base,    a second generator supported on said base,    a second magnetic brake device disposed beside said second idle wheel, for braking said second idle wheel, and    coupling means for coupling said shaft to said second idle wheel and said second generator, to drive said second idle wheel and said second generator.    
     
     
         2 . The exerciser as claimed in  claim 1 , wherein said coupling means includes two sector gears attached to said handles, and arranged to be rotated relative to said shaft by said handles respectively, a first pivot pin rotatably supported on said base, two first gears and two first pinions secured on said first pivot pin and rotated in concert with said first pivot pin, said first pinions being engaged with said sector gears respectively, a second pivot pin rotatably supported on said base and coupled to said second idle wheel and said second generator, for allowing said second idle wheel and said second generator to be rotated and driven by said second pivot pin, two second gears rotatably attached onto said second pivot pin with unidirectional bearings respectively, for allowing said second gears to be rotated unidirectionally relative to said pivot pin respectively, said second gears being meshed with said first gears respectively, and two second pinions rotatably attached onto said second pivot pin with unidirectional bearings respectively, for allowing said second pinions to be rotated unidirectionally relative to said pivot pin respectively, said second pinions are meshed with said sector gears respectively, said second idle wheel is rotated and driven continuously by said second pivot pin, via said second gears and said second pinions respectively, when said handles are pushed and pulled in reciprocating action by the user.  
     
     
         3 . The exerciser as claimed in  claim 2 , wherein said second pivot pin includes a pulley secured thereon and coupled to said second idle wheel, for allowing said second idle wheel to be rotated and driven by said pulley.  
     
     
         4 . The exerciser as claimed in  claim 3 , wherein said second idle wheel is rotatably attached to said base with an axle, and said axle is coupled to said pulley with a belt.  
     
     
         5 . The exerciser as claimed in  claim 3 , wherein said second idle wheel includes a second pulley secured thereto and coupled to said second electric generator, to cause said second electric generator to generate electric energy.  
     
     
         6 . The exerciser as claimed in  claim 1 , wherein said spindle includes a pulley secured thereon, and said first idle wheel is rotatably supported on said base and coupled to said pulley, for allowing said first idle wheel to be rotated and driven by said spindle via said pulley.  
     
     
         7 . The exerciser as claimed in  claim 6 , wherein said first idle wheel is rotatably attached to said base with an axle, and said axle is coupled to said pulley with a belt.  
     
     
         8 . The exerciser as claimed in  claim 6 , wherein said first idle wheel includes a second pulley secured thereto and coupled to said first generator, to cause said first generator to generate electric energy.
