Abstract
A cord retractor includes a support member, a first length of electrical cord, a spool, and a second length of electrical cord. The spool includes a helical groove on an outer surface of the spool. The helical groove has a width corresponding to a cross-sectional width of the first length of electrical cord, and the spool is rotatably mounted on the support member. The second length of electrical cord is electrically coupled to the first length of electrical cord. A first portion of the second length of electrical cord is secured at a rotating location, and a second portion of the second length of electrical cord is secured at a stationary location. The first length of electrical cord is selectively extendable from and retractable on the spool, and the second cord flexes to accommodate the movement of the rotating location with respect to the stationary location.
