Abstract
An electric curling iron includes an electrically heated cylinder having an exterior surface around which hair is wrapped for applying heat to the hair being curled and a partial cylindrical clamp member pivotally movable toward and away from the cylinder for clamping the hair against the cylinder. Rotation of the curling iron during use is facilitated by a main handle and clamp handle coupled to the heated cylinder and clamp member, respectively. The main handle and clamp handle are elongated members grippable in one hand of the user of the iron and are freely rotatable relative to the cylinder and clamp member so as to enable the cylinder and clamp member to be rotated within the hand of the user while hair is clamped between the clamp member and cylinder. The main and clamp handle are each provided with a locking mechanism selectively movable between a first position locking the respective handles against rotation and a second position wherein the respective handles are free to rotate. The locking mechanisms are each spring biased to the first position and are provided with a retaining element for releasably retaining the locking mechanism in its second position when moved into …
