ABSTRACT:
An improved winding device is provided for large scale umbrellas which is disposed at suitable position of the supporting metal rod of the umbrella. A cable is attached to the winding device such that by the winding and unwinding of the cable using the winding device, a runner can be moved up or down such that the stretchers and the associated panel can be extended or retracted. The winding device includes a housing having a hollow configuration, a crankshaft and a winding reel. The metal rod is provided with a shaft hole and the housing is enclosed around to the shaft hole. One side of the housing is provided with openings for receiving a crank handle and a winding reel. The winding device also includes a teethed and spring structure inside the housing which cooperatively exert a braking force on the rotation of the crankshaft, but the force can be overcome to allow movements of the crankshaft in both directions of rotation under force from the crank handle.
