Pedaling wheeled exerciser

Abstract

A pedaling wheeled exerciser includes a crank axle rotated with a crank and pedal assembly adapted to be operated by the user's feet, a first wheeled body coupled to the crank axle through a first unidirectional member to be rotated only in a clockwise direction, a resistance unit disposed to generate a resisting force against the rotation of the first wheeled body, a second wheeled body rotated with a hand operated wheel adapted to be operated by the user's hands, and a second unidirectional member disposed to couple the first and second wheeled bodies such that a rotational force generated as a result of the rotation of the second wheeled body is transmitted to the first wheeled body only when the second wheeled body is rotated in the clockwise direction.

1 . A pedaling wheeled exerciser comprising: 
 a base frame;    a crank axle mounted on and rotatable relative to said base frame about a first axis;    a crank and pedal assembly disposed to rotate said crank axle;    a first wheeled body surrounding and rotatable relative to said crank axle about the first axis;    a first unidirectional member disposed to couple said crank axle with said first wheeled body such that said first wheeled body is driven to rotate about the first axis in a clockwise direction only when said crank axle is rotated in the clockwise direction;    a resistance unit disposed to generate a resisting force against rotation of said first wheeled body;    an upright post extending uprightly from said base frame to terminate at an upper end;    a hand operated wheel rotatably mounted on said upper end of said upright post about a second axis parallel to the first axis;    a second wheeled body mounted to be rotatable relative to said crank axle about the first axis;    a force transmitting member disposed to couple said hand operated wheel with said second wheeled body so as to transmit a rotational force of said hand operated wheel to rotate said second wheeled body about the first axis; and    a second unidirectional member disposed to couple said first and second wheeled bodies such that a rotational force generated as a result of the rotation of said second wheeled body is transmitted to said first wheeled body only when said second wheeled body is rotated in the clockwise direction.    
     
     
         2 . The pedaling wheeled exerciser of  claim 1 , wherein said crank axle has first and second ends opposite to each other along the first axis, 
 said first and second wheeled bodies being disposed to surround said first and second ends, respectively,    said first wheeled body including a first wheel with an inner periphery which surrounds said crank axle, and a first tubular coupler which is connected to and which extends from said inner periphery along the first axis towards said second wheeled body,    said second wheeled body including a second wheel with an inner periphery, and a second tubular coupler which extends from said inner periphery along the first axis, which is surrounded by and which is spaced apart radially from said first tubular coupler with an annular space therebetween,    said second unidirectional member being in form of a ring, and being received in said annular space to transmit the rotational force of said second wheeled body to said first wheel only when said second wheeled body is rotated in the clockwise direction.    
     
     
         3 . The pedaling wheeled exerciser of  claim 2 , wherein said resistance unit includes an axle shaft mounted on and rotatable relative to said base frame about a third axis parallel to the first axis, and a resistance wheel disposed to be rotated with said axle shaft, said pedaling wheeled exerciser further comprising a transmitting belt which is trained on said first wheel of said first wheeled body and said axle shaft such that said transmitting belt drags said resistance wheel to rotate with said first wheeled body against the resisting force.  
     
     
         4 . The pedaling wheeled exerciser of  claim 3 , wherein said resistance unit further includes a resistance regulator which is disposed to regulate the resisting force against the rotation of said first wheeled body.  
     
     
         5 . The pedaling wheeled exerciser of  claim 2 , wherein said force transmitting member is a transmitting belt which is trained on said hand operated wheel and said second wheel of said second wheeled body.  
     
     
         6 . The pedaling wheeled exerciser of  claim 5 , further comprising a handgrip crank which is mounted to rotate said hand operated wheel about the second axis.  
     
     
         7 . The pedaling wheeled exerciser of  claim 1 , further comprising a seat frame extending from said base frame rearwardly to terminate at a rear end, and a seat adjustably mounted on said rear end of said seat frame.
