ABSTRACT:
A window shade assembly including a flexible window shade and a pair of guide tracks adapted to receive and support the window shade. The flexible window shade is sized to cover a window and formed to have a plurality of pleats therein. Each of the pleats is defined by a first fold portion and a second fold portion which together form a double fold. The flexible window shade is also formed to have the pleats substantially from one end to the other end thereof. The pair of guide tracks is adapted to be fixedly mounted to a frame of the window in spaced parallel relation. Each of the guide tracks is mounted to extend generally perpendicular to the longitudinal direction of the pleats. The guide tracks also are adapted to be spaced by a distance sufficient for positioning the pleats therebetween. By utilizing spring-biased rollers or non-rotational sliders and loose-fitting slide members, the flexible window shade can be moved in accordianlike fashion.
