Abstract: The sun shade system is for use over window panes, skylights and the like in homes, offices, greenhouses, and other applications. The system includes a plurality, preferably a pair, of parallel tracks disposable on opposite sides of a window or skylight or on window mullions, a plurality of shade carriers secured to and riding in the tracks and a flexible, foldable, resilient sun shade secured along its length to spaced ones of the carriers for movement with the carriers along the tracks. A shade mover such as a hand cord brake assembly or a motorized roller and cord assembly is also provided for urging the shade to a desired location relative to the tracks. Each track may be rectangular in cross-section, and curved or straight along its length, receives the shanks and rollers or slides of the carriers and includes an end stop. Each carrier can include a hook insertable through openings in the shade. A partition can be provided in the track to restrict oscillation of the rollers or slides and shank therein.
