Abstract

See full text

A method for operating a window cover utilizes an extendible window cover having a first rail, a second rail and a pair of lift cords. The first and second rails of the window cover are movable relative to each other. According to the method, at least one of the first rail and the second rail is moved in a first direction to cause the lift cords to unwind from the lift cord pulleys, thereby rotating a lift cord pulley shaft and a set of gears. Further, at least one of the first rail and the second rail is moved in a second direction to cause the lift cords to wind on the lift cord pulleys, with the lift cord pulley shaft rotating in an opposite direction.
