    Abstract: A flexible, retractable assembly for use as a door, space divider, covering or the like which comprises a sheet (20) such as Mylar TM polyester film having a permanent memory set to roll up on itself or otherwise retract automatically into a coil (42), 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 fluorescent light fixtures. The sheet may be combined with decorative finishes including a tambour composite structure providing aesthetic and functional advantages.

    Abstract: The retractable conduit of the invention comprises a sheet of memory-set polyester (4) formed as a conduit. To manufac- ture the memory-set strip, the polyester sheet (4) is wound into the desired retracted, e.g. coiled, position, heated and cooled. After this process the sheet of polyester will automatically assume the retracted position. In one embodiment, suitable as a splashblock, the distal end (47) of the polyester sheet (46) is wider than the end (48) attachable to a downspout (49). In another embodiment the polyester sheet (4) is sheathed in an elongated polyethylene tube (2), t o form a retractable hose. in a preferred embodiment, the distal end of the hose is supported on a spool ( 14) which will roll alo ng the ground as the hose is wound and unwound to fur- ther ensure that the hose retracts properly. The tube can also be provided with holes ( l8) to act as a sprinkler if desired.
