Abstract
A retractable awning for a recreational vehicle slide-out which prevents rain, snow and other debris from collecting on the roof of the slide-out. The awning is provided with an inner edge secured to the adjacent wall of the recreational vehicle immediately above the slide-out roof. The opposite edge of the awning is connected to a roller journaled on arms pivotally mounted on the outer face of the slide-out. A locking mechanism automatically prevents rotation of the roller when the slide-out is in a retracted position to prevent billowing of the awning when the recreational vehicle travels and automatically allows rotation of the roller when the slide-out moves away from the retracted position to wind and unwind the awning onto the roller. The lock mechanism includes a lock arm which blocks rotation of the roller only when the slide-out is in the retracted position so that no operations or manipulations are required by the operator to lock or unlock the lock mechanism.
