Electrically heated hair curling brush with selectively rotatable handle

Abstract

An electrically heated hair curling brush includes a generally cylindrical elongated handle having an elongated, thermally non-conductive brush support rotatably mounted within the handle and axially extending therefrom. An electric PTC heating element is housed within a brush cylinder non-rotatably mounted on the axially extending portion of the brush support. An elastically deformable elliptical locking ring within the handle surrounds the brush support and has a protrusion on the inner surface of each of its long sides engageable in recesses formed in the confronting surface of the brush support to lock the handle and brush support together so as to prevent relative rotation therebetween. A manually depressible button on one of the short sides of the locking ring projects through an opening in the handle. Selective manual depression of the button causes the long side of the locking ring to radially outwardly deflect thereby disengaging the projections from the recesses, and allowing rotation of the handle relative to the brush support. The lead wires for the heating element extend through the brush support to a connection block at the end of the support within the handle and are connected to a rotary connector thereon for rotary attachment to an electric power supply cord.
