ABSTRACT:
Electrical cord extension and retraction is achieved with a reel having a spool core around which the cord is wound. The spool core has two metal ends, to each of which is connected a wire of the electrical cord. Each metal end makes circular sliding electrical contact with a track mounted on the inside of a side housing member. Winding torque is supplied by an elastic member with parallel separated filaments that is fastened between the side members and held by opposing diametrical fingers positioned on the inside of the spool core.
