ABSTRACT:
A retractable cord reel, especially for electrical cord. The cord is carried by a pair of lightweight, electrically non-conductive hub-and-flange members secured together in sheave-like configuration. A tandem spring motor provides even tensioning of the cord, both when fully unwound and when fully retracted or wound up. Electrical continuity is provided as desired for grounding of the reel frame via a mounting arbor, which also may be non-conductive in large part so long as a sufficient part of it remains conductive.
