Integrated operating device of resistance and brake for exercise bike

Abstract

An integrated operating device has a brake mechanism having a brake cable, a resistance mechanism having a resistance cable, and an operating mechanism. The operating mechanism has a pivoting disk and an operating rod. The pivoting disk is pivotally mounted on a bike frame. An end of the resistance cable is connected to an edge of the pivoting disk. When the pivoting disk pivots, the resistance cable is winded around an outer annular surface of the pivoting disk. The operating rod is pivotally connected to the pivoting disk, is capable of turning the pivoting disk, and has a hook segment. The hook segment is connected to the brake cable. When the operating rod pivots relative to the pivoting disk, the hook segment moves to tighten or to release the brake cable. By this, the integrated operating device is capable of controlling the resistance mechanism and the brake mechanism with one operating rod.

What is claimed is: 
     
         1 . An integrated operating device adapted to be mounted on a bike frame and adapted to control a wheel; the integrated operating device having:

 a brake cable; 
   a resistance mechanism adapted to be mounted on the bike frame, adapted to apply rotating resistance to the wheel, and having
 a resistance cable; and 
   an operating mechanism having
 a pivoting disk adapted to be pivotally mounted on the bike frame; an end of the resistance cable connected to an edge of the pivoting disk; wherein when the pivoting disk pivots, the resistance cable is winded around an outer annular surface of the pivoting disk such that the pivoting disk is capable of tightening or releasing the resistance cable; 
 a connecting unit securely mounted on the pivoting disk; and 
 a operating rod being capable of turning the pivoting disk via the connecting unit and having
 a pivoting segment pivotally mounted on the connecting unit; 
 a hook segment securely mounted on the pivoting segment and connected to the brake cable; and 
 a shaft segment securely mounted on the pivoting segment and being capable of moving relative to the pivoting disk by the pivoting segment pivoting relative to the connecting unit; wherein when the shaft segment moves, the hook segment moves along with the shaft segment to tighten or to release the brake cable.

         6 . The integrated operating device as claimed in  claim 4 , wherein
 the pivoting disk has
 multiple positioning grooves formed on a side surface of the pivoting disk and arranged in an arced line; and 
   the operating mechanism has
 a positioning unit adapted to be mounted on the bike frame; wherein when the pivoting disk pivots, the positioning unit selectively engages in one of the positioning grooves to position the pivoting disk. 
   
     
     
         7 . The integrated operating device as claimed in  claim 1 , wherein
 a notch is formed on the outer annular surface of the pivoting disk and concaved toward a center of the pivoting disk; and   the pivoting segment and the hook segment of the operating rod are located in the notch.   
     
     
         8 . The integrated operating device as claimed in  claim 6 , wherein
 a notch is formed on the outer annular surface of the pivoting disk and concaved toward a center of the pivoting disk; and   the pivoting segment and the hook segment of the operating rod are located in the notch.   
     
     
         9 . The integrated operating device as claimed in  claim 1 , wherein a connecting point between the hook segment of the operating rod and the brake cable and a pivoting point between the pivoting segment of the operating rod and the connecting unit are respectively located on two sides of the pivoting disk. 
     
     
         10 . The integrated operating device as claimed in  claim 8 , wherein a connecting point between the hook segment of the operating rod and the brake cable and a pivoting point between the pivoting segment of the operating rod and the connecting unit are respectively located on two sides of the pivoting disk. 
     
     
         11 . The integrated operating device as claimed in  claim 1 , wherein the connecting unit is securely mounted on one of two sides of the pivoting disk, and is pivotally connected to the operating rod on the other one of the two sides of the pivoting disk. 
     
     
         12 . The integrated operating device as claimed in  claim 10 , wherein the connecting unit is securely mounted on one of the two sides of the pivoting disk, and is pivotally connected to the operating rod on the other one of the two sides of the pivoting disk.
