Claim Text:
1. A cord retractor comprising: a support member; a first length of electrical cord; a spool comprising a helical groove on an outer surface of the spool, wherein the helical groove comprises a width corresponding to a cross-sectional width of the first length of electrical cord, wherein the spool is rotatably mounted on the support member; and a second length of electrical cord electrically coupled to the first length of electrical cord and helically extending within, radially separated from, and co-axially relative to the spool, wherein 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, wherein the rotating location moves with the spool and the stationary location remains stationary with respect to the support member; wherein the first length of electrical cord is selectively extendable from and retractable on the spool and wherein the second length of electrical cord flexes to accommodate the movement of the rotating location with respect to the stationary location while maintaining electrical communication between the rotating location and the stationary location, and wherein when the first length of electrical cord is selectively retracted the spool rotates and the first length of electrical cord is guided into the helical groove.
