Abstract
Abstract A unitary lightweight, inexpensive, simple telescoping frame is provided for handling and storing an extension cord or similar flexible line in a figure eight configuration. The device eliminates the tangling and twisting associated with the use of such cords and provides convenient, flat, hanging storage and presents the cord so that it can be readily payed out and extended with substantially no resistance or tangling.

A lightweight frame for handling and storing cord or the like in a figure eight configuration comprising: a telescoping backbone having two ends; a transversely extending arcuate end piece fastened to each end of said telescoping backbone; each of said arcuate end pieces having a middle section with two ends; said middle section having a bottom, a front wall, and a rear wall to define a U-shaped channel sufficient in size to accommodate a stored cord or the like; said middle section rear wall having an outer edge which is straight to permit standing of the frame without rolling; a tangent section extending from each of said ends of said arcuate end pieces in a direction parallel to said telescoping backbone; each of said tangent sections having only a rear wall and a bottom with said bottom having a width approximately the same width as said bottom of said middle section; an inward curved section extending from each of said tangent sections in a direction toward the center of said frame; each of said inward curved sections having only a bottom and a rear wall; a projection leg extending forwardly from said bottom of said inward curved section to serve both to increase the width of said bottom of said inward curved section and to serve as a support for said frame when it is placed face down on a horizontal surface; and an open handle-shaped transversely extending footplate affixed to said backbone at approximately the middle thereof to serve both as a carrying handle and a hold down for said frame when a cord or the like is being wound thereon.
