ABSTRACT:
A collapsible electric curling iron includes an elongated hollow handle open at one end and an elongated, generally cylindrical heat conductive housing mounted on the handle for movement between an operative use position where the housing extends out of the handle through the open end and an inoperative storage position where the housing is confined within the handle. A cap on the inner end of the housing cooperates with a collar and guides on the handle to prevent side-to-side or "rocking" movement of the housing in a direction transverse to the longitudinal axis of the handle during movement between the operative and inoperative positions. The housing has a longitudinal bore, generally polygonal in transverse cross section, which accommodates a thin planar electric heating element placed diagonally across the bore and having side edges engaged in diametrically spaced corners of the bore. Hair grooming members in the form of rows of aligned combining teeth or bristles are removably received in longitudinal grooves in the outer peripheral surface of the housing.
