Abstract
A flexible, retractable assembly for use as a door, space divider, covering or the like which comprises a sheet such as Mylar polyester film having a permanent memory set to roll up on itself or otherwise retract automatically into a coil, accordion, or other compact configuration. The assembly is adapted to be stored on one side of an opening and then guided across the opening to fully or partially cover the opening. The permanent memory set of the sheet permits it to retract at least partially under its own force to eliminate or minimize the need for separate rewinding apparatus. The sheet may substitute for a variety of standard products including entryway doors, closet, cabinet and shower doors, screen doors and windows, room dividers, machinery guards and covers for various items such as florescent light fixtures. The sheet may be combined with decorative finishes including a tambour composite structure providing aesthetic and functional advantages.
