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.
