ABSTRACT:
An electrically heated hair roller includes a roller body defining an exterior curling surface and a hair clamp pivotally mounted to the roller body and movable toward and away therefrom between in open position allowing hair to be wound on the body and a closed position clamping wound hair against the curling surface. An electric heater within the roller body heats the curling surface and is powered by a battery contained within a compartment formed in the clamp. Cooperative separable electrical plug and jack elements on the clamp and roller body electrically interconnect the battery to the electric heater. The connector elements also operate as a mechanical fastener for securing the clamp in the closed position. The arrangement is such that the electrical interconnection is interrupted upon release of the clamp from its closed position. The battery may be rechargeable and a combination battery charger-storage rack may be provided for holding the curler and recharging the battery without need to remove the battery from the battery compartment.
