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.

An electric appliance having a handle, an electric cord and a cord lock, said cord lock comprising: a body rotatably mounted to said handle for movement between a first operative position and a second operative position, said body further including a first surface for supporting a plurality of loops

An electric appliance having a handle, an electric cord and a cord lock, said cord lock comprising: a body rotatably mounted to said handle for movement between a first operative position and a second operative position, said body further including a first surface for supporting a plurality of loops of said cord in said first operative position, an opposite second surface for selectably supporting a single loop of said cord in said second operative position, and a cam portion adjacent said second surface which extends radially outward beyond said second surface and thereby forms a shoulder between said cam portion and said second surface to restrict said single loop of said cord supported by said second surface from being released when said body is rotated to said second operative position, said first surface being inclined so as to slope downwardly toward said handle when said body is in said first operative position so that said single loop to be supported when said body is in said second operative position is urged to slide to an position adjacent said handle, said cam portion having a outer surface inclined to slope down and away from said handle when said body is in said second operative position such that rotation of said body from said first operative position to said second operative position results in the sliding release of all of the cord loops along said inclined outer surface of the cam portion but said single loop which is supported on said second surface between said shoulder and said handle, and wherein the height of said shoulder above said second surface and the lateral spacing of said shoulder from said handle are each substantially equal to the width of said cord, to thereby ensure that only said single cord loop is held when said body is rotated to said second operative position, and a tab fixedly mounted to said handle above said body, wherein said tab projects laterally outward from said handle and cooperates with said handle, said second surface and said shoulder to substantially enclose said supported single cord loop when said body is rotated to said second operative position.
