ABSTRACT:
A motorized awning is provided having a rotatably supported winding shaft housed in an awning box for an awning cloth capable of being wound on the winding shaft, the 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 by means of a resilient coupling member which permits at least a limited relative rotary motion between the winding shaft and the output shaft of the drive motor, a first limit switch for controlling the motor current when the cloth of the awning is retracted and a second limit switch for controlling the motor current when the cloth is extended, so that after the actuation of the limit switches the drive motor can be started only with the opposite sense of rotation. The limit switches are activated when the awning cloth is fully extended or retracted and the resilient coupling member has permitted the limited relative rotary motion between the winding shaft and the motor output shaft.
