Abstract: A flexible guide for a door includes straps that are mounted in pairs along either side of a doorway. The straps for each pair are generally parallel, facing each other, and spaced apart to create a gap or channel between the two.

Abstract: A covering system for apertures, such as windows, has a cross bar that is slidably mounted between a pair of tracks. Each end of the cross bar is connected to a belt that circulates in its respective track. The belts positively engage respective pulleys which are connected by a shaft.
