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.

Abstract: A retractable conduit formed from a sheet of memory-set polyester. To manufacture the memory-set strip, the polyester sheet is wound into a desired coiled position. It is then heated and cooled in a manner to memory-set the sheet in a coiled form. After this process the sheet of polyester will automatically return to the coiled position after it has been uncoiled. In one form, suitable as a splashblock, the distal end of the polyester sheet is wider than the end attachable to a downspout. In another form the polyester sheet is sheathed in an elongated polyethylene tube, to form a retractable hose. In a preferred form, the distal end of the hose is supported on a spool which will roll along the ground as the hose is wound and unwound to further ensure that the hose retracts properly. The tube can also be provided with holes to act as a sprinkler if desired.
