Bicycle Trainer

Abstract

A bicycle trainer is disclosed. The bicycle trainer includes a supporting frame, a hollow roller, an axle, at least one linking part, a fan and a resistance generator. The supporting frame suspends the driving wheel of a bicycle from the ground. The hollow roller presses up against the driving wheel of the bicycle. The axle is located in the hollow roller and pivotally connected to the supporting frame. The linking part connects the axle and the hollow roller. The fan is located in the hollow roller. The resistance generator provides resistance to the axle.

1 . A bicycle trainer comprising:
 a supporting frame for suspending the driving wheel of a bicycle from the ground;   a hollow roller for pressing up against the driving wheel of the bicycle;   an axle located in the hollow roller and pivotally connected to the supporting frame;   at least one linking part connecting the axle and the hollow roller;   a fan located in the hollow roller; and   a resistance generator for providing resistance to the axle.   
     
     
         2 . The bicycle trainer of  claim 1 , wherein the fan comprises:
 at least one blade connected to the inner wall of the hollow roller.   
     
     
         3 . The bicycle trainer of  claim 1 , wherein the fan comprises:
 at least one blade connected to the axle.   
     
     
         4 . The bicycle trainer of  claim 1 , wherein the fan comprises:
 an impeller detachably connected to the axle.   
     
     
         5 . The bicycle trainer of  claim 1 , wherein the axle comprises:
 a tube; and   a shaft coupled to the tube and pivotally connected to the supporting frame, wherein the resistance generator is connected to the shaft.   
     
     
         6 . The bicycle trainer of  claim 1 , wherein the fan is located at one end of the hollow roller, thereby cooling the resistance generator. 
     
     
         7 . The bicycle trainer of  claim 1 , further comprising:
 a balance-weight wheel, wherein the balance-weight wheel and the resistance generator are connected to opposite ends of the axle.   
     
     
         8 . The bicycle trainer of  claim 1 , further comprising:
 a detachable connecting member detachably connecting the axle to the supporting frame.   
     
     
         9 . A bicycle trainer comprising:
 a supporting frame for suspending the driving wheel of a bicycle from the ground;   an axle pivotally connected to the supporting frame;   a fan connected to the axle;   a hollow roller surrounding the axle and the fan;   at least one linking part connecting the hollow roller and the axle; and   a resistance generator for providing resistance to the axle.   
     
     
         10 . The bicycle trainer of  claim 9 , wherein the fan comprises:
 an impeller detachably connected to the axle.   
     
     
         11 . The bicycle trainer of  claim 9 , wherein the axle comprises:
 a tube; and   a shaft coupled to the tube and pivotally connected to the supporting frame, wherein the resistance generator is connected to the shaft.   
     
     
         12 . The bicycle trainer of  claim 9 , wherein the fan is located at one end of the hollow roller, thereby cooling the resistance generator. 
     
     
         13 . The bicycle trainer of  claim 9 , further comprising:
 a balance-weight wheel, wherein the balance-weight wheel and the resistance generator are connected to opposite ends of the axle.   
     
     
         14 . The bicycle trainer of  claim 9 , further comprising:
 a detachable connecting member detachably connecting the axle to the supporting frame.
