Hand driving cycle exerciser

Abstract

A hand driving cycle exerciser includes a base having a front wheel device and a rear fork to support a rear wheel with an axle. Two rotary members are rotatably attached onto the rear wheel with unidirectional bearings, two followers are rotatably engaged onto the axle and coupled to the rotary members, for unidirectionally rotating the rear wheel via the rotary members and the unidirectional bearings, two handles are rotatably attached to the base and connected to the followers, to unidirectionally rotate the rear wheel via the followers and the rotary members and the unidirectional bearings with the handles.

1 . A hand driving cycle exerciser comprising: 
 a base including a front portion having a front wheel device attached thereto, and including a rear fork attached thereto,    a rear wheel rotatably attached to said fork of said base with an axle, to allow said rear wheel to be rotated relative to said fork of said base,    two rotary members rotatably attached onto said rear wheel with unidirectional bearings, to allow said rotary members to be rotated relative to said rear wheel unidirectionally,    two followers rotatably engaged onto said axle, and coupled to said rotary members, for unidirectionally rotating said rear wheel via said rotary members and said unidirectional bearings,    two handles rotatably attached to said base, and    means for connecting said handles to said followers respectively, to unidirectionally rotate said rear wheel via said followers and said rotary members and said unidirectional bearings with said handles.    
     
     
         2 . The hand driving cycle exerciser as claimed in  claim 1 , wherein said base includes a pair of posts extended therefrom and each having a pin laterally extended therefrom to rotatably attach said handles to said base.  
     
     
         3 . The hand driving cycle exerciser as claimed in  claim 2 , wherein each of said handles includes a sleeve provided thereon and rotatably engaged onto said pins of said posts of said base respectively, to allow said handles to be rotated relative to said base in reciprocating action.  
     
     
         4 . The hand driving cycle exerciser as claimed in  claim 1 , wherein each of said handles includes an extension adjustably secured thereon, and having a hand grip provided on top thereof, for being grasped by users.  
     
     
         5 . The hand driving cycle exerciser as claimed in  claim 1 , wherein each of said followers includes a pole extended therefrom, and said connecting means includes two cranks secured to said poles and rotated in concert with said poles respectively, and a pair of levers coupled between said handles and said cranks, to allow said handles to drive said followers and said poles relative to said axle by said levers and said cranks.  
     
     
         6 . The hand driving cycle exerciser as claimed in  claim 1 , wherein each of said rotary members includes a plurality of notches formed therein, and each of said followers includes a plurality of teeth extended therefrom and engaged into said notches of said rotary members, to unidirectionally rotate said rear wheel via said rotary members and said unidirectional bearings.  
     
     
         7 . The hand driving cycle exerciser as claimed in  claim 1 , wherein said base includes a front tube secured to said front portion thereof and extended vertically, a shaft rotatably secured in said front tube of said base to attach said front wheel device thereto, and means for rotating said shaft relative to said front tube of said base.  
     
     
         8 . The hand driving cycle exerciser as claimed in  claim 7 , wherein said front wheel device includes at least one front wheel rotatably attached to said front portion of said base with a pivot rod, and coupled to said shaft with a link.  
     
     
         9 . The hand driving cycle exerciser as claimed in  claim 8 , wherein said shaft includes a bar secured thereto and extended forwardly from said shaft, for coupling to said link.  
     
     
         10 . The hand driving cycle exerciser as claimed in  claim 7 , wherein said rotating means includes a platform rotatably attached to said base, and means for coupling said platform to said shaft.  
     
     
         11 . The hand driving cycle exerciser as claimed in  claim 10 , wherein said coupling means includes a connector coupled between said platform to said shaft.
