ABSTRACT:
A cord retractor for retracting a cord of an electrical appliance, includes a housing adapted to be mounted to a supporting surface. A drum is rotatably mounted in the housing. Electrical connections are provided for interconnecting the drum and housing and for connecting the housing to a source of electricity. The housing is provided with access to the drum for introduction of a cord of an electrical appliance into the housing to be reeled onto the drum and connected to the electrical connections so that electricity is supplied to the appliance. A spring is on the housing and is connected to the drum and tends to rotate the drum in the direction causing the cord to be reeled onto the drum and retracted into the housing. Releasable retention structure is provided to automatically retain the drum in position after a desired amount of cord has been reeled from the drum out of the housing as the appliance is being used and, when released, permits the spring to rotate the drum in the direction to reel the cord back onto the drum.
