Awning with resilient motor coupling

A motorized awning having a rotatably supported winding shaft housed in an awning box for an awning cloth capable of being wound on said winding shaft, said cloth being secured along one edge on the winding shaft and along the opposite edge on an extendable rod, an immovably supported drive motor, its output shaft coupled with the winding shaft for the automatic retraction of the awning, a first limit switch for controlling the motor current when the cloth of the awning is retracted operating in dependency upon the rotary position of the winding shaft and connected to a timing device in the motor power circuit so that on actuation of this first limit switch the drive motor continues to run for a predetermined period of time in the sense of further winding of the cloth of the awning, and a second limit switch for controlling the motor current when the cloth is extended, so that after the actuation of said limit switches the drive motor can be started only with the opposite sense of rotation, the improvement comprising;

• a resilient coupling member including a spring elastic element positively coupling the output shaft of said motor with the winding shaft at least in the sense of direction of winding of the cloth of the awning, the input side of said coupling member being connected with said output shaft and its output side being connected with said winding shaft, said resilient coupling member permitting at least a limited relative rotary motion between said winding shaft and said output shaft of said drive motor.
