ABSTRACT OF DISCLOSURE The apparatus is a Portable Retractable Extension Cord in which a cord is wound over a spring-loaded reel in a plastic encasing. A male attachment plug is affixed to the side of the encasing with its wires connected to three separate metal plates on a cam inside the encasing. The female attachment plug is connected to a 15 metre 3-wire single-phase cord wound over the reel inside the encasing and its wires riveted to three slip rings at its side. When used outdoors,the apparatus is mounted on a stake which allows it to rotate 360 degrees on its axis. The torsional spring-loaded reel retracts the cord into the encasing when it is pulled, eliminating slack but retaining electrical contact between the slip rings and the plates whether or not the reel is rotating.The main application of the apparatus is for use with electrical lawnmowers as existing outdoor extension cords must be manually wound or placed aside out of the way of the lawnmower's blades and the few retractable cords available in the market are limited for indoor use at workshops or come as part and parcel of vacuum cleaners. This apparatus can be used both indoors and outdoors with a variety of electrical devices.
