ABSTRACT:
A retractable rigid window awning includes a number of U-shaped panels pivotally attached to a building on the sides of a window. In the retracted position, the panels are disposed above the window, in tiers. Each panel has a pair of actuators that enable its extension and retraction. Each actuator is attached to the panel at one end and to a movable nut at the other end via articulated joints. The nuts are installed on a driving screw attached to the building. The awning is extended by rotating the screw, which causes the nuts to travel along the screw. The actuators push their respective panels out and tilt them down. Depending on the length of actuators, panels travel different distances from the building creating a continuous shade over the window. The awning is retracted by rotating the screw in the opposite direction.
