Compound bicycle exercising device

Abstract

A compound bicycle exercising device includes a base, a pair of foot pedals rotatably attached to the base with a spindle and cranks, for being operated by users. A pair of handle stems are each pivotally attached to the base with an axle, for being pulled and pushed and operated by the users, and a pair of handgrips are rotatably attached to the upper portions of the handle stems and rotatable inwardly and outwardly relative to the handle stems, to allow the handle stems to be easily pulled toward and away from the users.

1 . A compound bicycle exercising device comprising: 
 a base,    a pair of foot pedals rotatably attached to said base with a spindle and cranks, for being operated by users,    a pair of handle stems each having a lower portion pivotally attached to said base with an axle, for being pulled and pushed and operated by the users, said handle stems each including an upper portion, and    a pair of handgrips rotatably attached to said upper portions of said handle stems respectively, and rotatable inwardly and outwardly relative to said handle stems, to allow said handle stems to be easily pulled toward and away from the users.    
     
     
         2 . The compound bicycle exercising device as claimed in  claim 1 , wherein said handle stems each includes a casing provided on said upper portions thereof, and said handgrips each includes a shaft extended therefrom, and rotatably attached to said casing, to allow said handle stems to be rotatably attached to said casing with said shafts.  
     
     
         3 . The compound bicycle exercising device as claimed in  claim 2 , wherein said casing includes a bore formed therein, and a peripheral flange extended inwardly from one end thereof, to form an aperture therein, and to receive said shaft.  
     
     
         4 . The compound bicycle exercising device as claimed in  claim 3 , wherein said casing includes at least one bearing disposed in said bore thereof, and engaged with said shaft, to rotatably attach said shaft to said casing.  
     
     
         5 . The compound bicycle exercising device as claimed in  claim 4 , wherein said shaft includes a retaining ring attached thereto, and engaged with said at least one bearing, to rotatably attach said shaft to said casing.  
     
     
         6 . The compound bicycle exercising device as claimed in  claim 2 , wherein said handgrips are each extended from a bracket, and said bracket includes said shaft extended therefrom and rotatably attached to said casing.  
     
     
         7 . The compound bicycle exercising device as claimed in  claim 6 , wherein said bracket includes s switch button provided thereon, for being actuated by the users, and for adjusting resistive forces applied to said foot pedals.  
     
     
         8 . The compound bicycle exercising device as claimed in  claim 6 , wherein said bracket includes a switch button provided thereon, for being actuated by the users, and for adjusting resistive forces applied to said handle stems.
