By providing a hair curler/roller which comprises a unique, distinctive construction that enables the hair roller/curler to be heated substantially more rapidly than prior art constructions, an easily used, hair curler/roller and heating system is obtained which is capable of providing rapid heating of the hair curler/roller. In addition, the heating system employed for transferring heat to the hair curler/roller is also constructed in a unique manner that optimizes heat transfer, while also being constructed efficiently and inexpensively. In accordance with the present invention, the hair curler/roller incorporates an elongated cylindrically shaped body or core formed from heat retaining metal, such as aluminum. In addition, the cylindrical body incorporates a plurality of thin, interconnected wall members peripherally surrounded by a cylindrical outer wall. Preferably, the unique metal core is easily manufactured by extrusion, thereby achieving a hair roller/curler which is easily constructed as well as capable of absorbing and retaining heat rapidly and efficiently.
A hair curler assembly comprising:
A hair curler constructed for being mounted on an elongate heat producing rail, said curler comprising a central body formed from heat absorbing material, said central body comprising an outer cylindrically shaped tubular member forming the outer surface of the central body, a pair of arcuately curved wall members positioned within the tubular member in juxtaposed facing relationship with each other, and fins extending radially between one of the respective wall members and the tubular member to connect the wall members to the tubular member, the tubular member having a length and each of the fins having a length that is substantially equal to the length of the tubular member, the central body defining a mounting slot in the tubular member of the central body extending along a diameter of the tubular member and extending from one axial end thereof inwardly so the hair curler can be mounted on the heating rail with the central axis of the hair curler being perpendicular to the rail.
A hair curler constructed for being mounted on an elongate heat producing rail, said curler comprising a central body made from a heat absorbing material, said central body comprising an outer cylindrically shaped member having a length and a first diameter, and an inner cylindrically shaped member having a length and a second diameter less than the first diameter, the inner cylindrically shaped member being coaxially aligned with the outer cylindrically shaped member, and a plurality of radially extending fins connecting the inner cylindrically shaped member to the outer cylindrically shaped member, the inner and outer cylindrically shaped members being free from direct contact along their entire lengths, the central body defining a mounting slot in the outer cylindrical member along a diameter thereof and extending from one end thereof inwardly so the hair curler can be mounted to a heating rail with the central axis of the hair curler being perpendicular to the rail.
