Abstract

A hair shaping apparatus is provided employing one or more hollow rollers. The rollers can be arranged in concentric fashion and electrically heated by an activator unit, wherein one end of the activator unit is inserted into one end of the concentrically arranged rollers, and the other end of the activator unit can be plugged into an electrical wall outlet. The activator unit can be reversed for storage, whereby the AC plugs which connect to the wall outlet are inserted into the hollow opening of the roller to present a low-profile configuration for ease of portability. One or multiple receptacles can be connected to an activator unit, wherein the activator unit is connected to a wall outlet in order to heat a plurality of singular or concentrically arranged hollow rollers connected to the receptacles.

Claims

1. An apparatus for shaping hair adapted to be heated by applying an external energy source to the apparatus, comprising a cylindrical;

hollow first roller having opposing ends and an inner wall and an outer wall for defining an open tubular member having an open cavity extending the length of the roller, and a conductive material placed between said opposing ends and between the inner and outer wall, the conductive material comprising at least two arcuate metal plates with a metal coupling at opposing ends of each metal plate, and a heating element disposed between the metal couplings, said arcuate metal plates surrounding a mid-section of said hollow first roller between said opposing ends such that said heating element is coupled between a metal coupling of one metal plate and a metal coupling of another metal plate, whereby the external energy source is placed in contact with the conductive material at one end of said opposing ends of the roller.

2. An apparatus for shaping hair adapted to be heated by applying an external energy source to the apparatus, comprising a cylindrical, hollow first roller having opposing ends and an inner wall and an outer wall for defining an open tubular member having an open cavity extending the length of the roller, and a conductive material placed between said opposing ends and between the inner and outer wall, the conductive material comprising at least two arcuate metal plates with a metal coupling at opposing ends of each metal plate, and a heating element disposed between the metal couplings, each said arcuate metal plate comprises a spaced plurality of openings traversing said plate, whereby the external energy source is placed in contact with the conductive material at one end of said opposing ends of the roller.

3. An apparatus for shaping hair, comprising:

a cylindrical, hollow first roller having opposing ends and a conductive material placed between said opposing ends;

a first contact associated with said hollow first roller and coupled between said conductive material and one of said opposing ends;

a cylindrical, hollow second roller having an outside diameter less than an inside diameter of said hollow first roller, said hollow second roller having opposing ends and a second conductive material placed between said opposing ends; and

a second contact coextensive with said hollow second roller and coupled between said second conductive material and one end of said hollow second roller.

4. The apparatus as recited in claim 3, further comprising:

an activator unit having opposing first and second sides of circular cross-section;

an AC plug extending from said first side; and

at least two receptacles attached to said AC plug and extending in spaced relation from said second side, wherein said second side is adapted to partially extend into one end of said hollow second roller and one of said at least two receptacles is adapted to connect with said second contact.

5. The apparatus as recited in claim 3, further comprising:

an activator unit having opposing first and second sides of circular cross-section;

an AC plug extending from said first side; and

at least two receptacles attached to said AC plug and extending in spaced relation from said second side, wherein said second side is adapted to partially extend into one end of said hollow first and second rollers arranged in concentric fashion, and wherein said at least two receptacles are adapted to connect with said first and second contacts, respectively.

6. The apparatus as recited in claim 3, further comprising:

an activator unit having opposing first and second sides of circular cross-section; and

an AC plug extending from said first side, and wherein said first side is adapted to partially extend into one end of said hollow first and second rollers arranged in concentric fashion.

7. An apparatus for shaping hair, comprising:

a cylindrical, hollow first roller having opposing ends and a conductive material placed between said opposing ends;

a first contact coextensive with said hollow first roller and coupled between said conductive material and one of said opposing ends;

and activator unit having opposing first and second sides of circular cross-section, wherein an AC plug extends from said first side and a first receptacle connected to said AC plug extends from said first side to said second side; and

a cylindrical, hollow second roller concentrically configured inside said hollow first roller, wherein the first side of said activator unit is adapted to partially extend into one end of said hollow first and second rollers such that said AC plug faces inward into said hollow first roller and the concentricity of said hollow first and second rollers is fixedly maintained.

8. The apparatus as recited in claim 7, wherein the second side of said activator unit is adapted to partially extend into one end of said opposing ends such that said first receptacle frictionally connects with said first contact and said AC plug is exposed for connection to an AC wall socket.

9. The apparatus as recited in claim 7, wherein the first side of said activator unit is adapted to partially extend into one end of said opposing ends such that said first receptacle frictionally connects with said first contact and said AC plug faces inward into said hollow first roller.

10. The apparatus as recited in claim 9, wherein the second side of said activator unit further comprising a second receptacle spaced radially inside said first receptacle.

11. The apparatus as recited in claim 10, further comprising a cylindrical, hollow second roller having a second contact coextensive therewith, wherein said hollow second roller is concentrically configured inside said hollow first roller, and wherein the second side of said activator unit is adapted to partially extend into one end of said hollow first and second rollers such that said first and second receptacles connect with respective said first and second contacts.

12. The apparatus as recited in claim 11, further comprising a plurality of concentrically arranged hollow first and second rollers and a plurality of activator units, each concentrically arranged hollow first and second rollers having respective first and second contacts extending in frictional mating arrangement with respective first and second receptacles of each of said plurality of activator units.

13. The apparatus as recited in claim 12, wherein said frictional mating arrangement provides thermal conduction between said plurality of concentrically arranged hollow first and second rollers and respective plurality of activator units.
