Abstract

An apparatus and uniformly heating a plurality of hair curlers by passing a current of hot air longitudinally through the hair curler body includes a hollow case having an upper wall forming a support surface in which is formed a central air inlet opening into which the hot air discharge nozzle of a portable electric air heating device is inserted. A plurality of hot air discharge ports are radially centered around the inlet opening and each port is provided with a holding member for supporting a hair curler in the path of hot air discharged from the port. The curler body is provided with an inner element able to accumulate and conserve heat. When the curlers are mounted at the ports on the holding members, hot air blown into the case will pass into the curlers and heat them. Each curler may include a cover for receiving hot air from within the curler and deflecting the hot air to flow in the reverse direction along the outer wall of the curler.

Claims

1. Apparatus, comprising

a hair curler support having a hollow interior and a support surface formed with a central hot air inlet opening and a plurality of hot air discharge ports arranged radially about in spaced relationship from and centered around said inlet opening, said opening and said discharge ports communicating with the interior of said support,

means for holding a hair curler on said support surface at each of said ports in the path of air discharged from the port,

a hot air generating means for supplying hot air into said support through said opening for discharge from each of said ports.

2. Apparatus according to claim 1, wherein

said hot air generating means comprises a portable forced circulation air heating device having a hot air discharge nozzle,

said hair curler support is in the form of a hollow case having an upper wall which forms said support surface and in which is formed said plurality of hot air discharge ports and said support includes an opening means forming said inlet opening and into which is inserted the discharge nozzles of said portable forced circulation air heating device.

3. Apparatus according to claim 2, characterized in that the opening means includes an interior wall with steps adapted for the selective reception of different diameter air discharge nozzles.

4. Apparatus according to claim 3, wherein

the case includes pins inserted into holes formed in the steps of the opening means, said pins constituting means for holding the forced circulation air heating device in position on the case.

5. Apparatus according to claim 2, wherein

the opening means into the case is located in the center of the upper wall of the case, and said air discharge ports with said holding means are distributed around said opening means.

6. Apparatus according to claim 5, wherein

said case is round and the bottom wall thereof includes means for permitting the case to rotate about a central axis.

7. Apparatus according to claim 1, wherein

said holding means is disposed in the hot air discharge ports and form therewith a constriction means for bringing about a greater slowing down of the air flow than that caused by said hair curler when mounted at said ports.

8. Apparatus as set forth in claim 7, wherein

said holding means are frustoconical members narrowing into said ports.

9. The apparatus as set forth in claim 1, wherein

said support is formed with a rounded projection opposite to and facing toward said central inlet opening and constituting means for directing the hot air entering from said inlet opening of said support radially outwardly toward said hot air discharge ports.

10. A hair curling apparatus comprising a plurality of hollow bobbin-shaped hair curlers,

support means for supporting the hair curlers, said support means being formed with a central inlet opening constituting means for entrance of hot air as well as a series of ports constituting means for the discharge of the hot air, said ports being arranged radially about in spaced relationship from and centered around said inlet opening, said ports being adapted to be fed by a hot air generator communicating with said inlet opening and being adapted to communicate with an inner part of the hair curlers,

said support means being formed as a hollow case having an upper wall upon which said curlers are supported and in which said ports are formed,

said hair curlers being mountable on said support means in communication with said ports and each containing an axial element made of a material means for accumulating and retaining heat, and said material means being formed with at least one longitudinal passage open at two extremities of the hair curler and communicating with said port.
