ABSTRACT:
An electrical appliance including an electric cord, and a cord lock comprising a rotatable body provided with a handle radially extending therefrom and an oppositely extending cam provided with a shoulder. In a first position, the handle extends upwardly and the cord lock functions in a storage capacity for the entire cord. In a second position, the cam portion extends upwardly and the shoulder automatically retains only one loop of the cord. The rest of the loops in this position are released by an inclined surface provided on the cam. In a third position, the body is rotated so that the handle extends horizontally. At this position, all of the loops may be collectively removed from the cord lock by the user.
