Abstract
A mechanism for releasably retracting and storing a length of electrical cord (96,98,100,102,104) is formed of first and second pairs of cord pulleys (60,62,82,84) mounted at opposite ends of an elongated retractor frame (18). An intermediate section of a cord is stored in the frame and has one end (92) of the stored section fixed to the frame, with the other end (106) extending from the frame. The stored cord section is wound around the two pairs of cord pulleys (60,62,82,84), and one pair of pulleys (60,62) is slidably mounted for motion toward the other pair of pulleys (82,84) with a detachable latch (126) to lock the movable pulleys in position adjacent the fixed pulleys in a cord extended position. Springs (70,72) entrained around force direction changing spring pulleys (66,68) constantly urge the slidable pulleys (60,62) to an initial position wherein the cord is retracted. Pulling on one end (106) of the cord extends a length of the stored cord section from the frame and latches the mechanism in cord extended position. A second pull on the cord releases the latch to enable the springs to retract the cord into the mechanism.
