Heated hair curler

The invention relates to hair curlers, in particular hair curlers with self-contained heating units that can be electrically heated to their operating temperature quickly, easily and safely can be heated so that the heat is conducted to the hair that is wrapped around the outside of the curler.

Hair wrapping, as it is nowadays at home and in barber shops practiced involves dividing a person's hair into different strands or lengths. The single ones Strands are usually wound evenly around a hair curler and by wetting the wound strand with water or chemical substances or by adding Heat or the like. On the strand is achieved that the strand assumes the shape that the hair curler takes on. is borrowed. Hair curlers come in a variety of diameters from about 12.7 mm up to 76.2 or 101.6 mm (1/2 inch up to 3 or 4 inches) to form the various sized curls, which are required by fashion or the person concerned.

It has long been known that hair-curling can be done faster and more effectively when the hair is

is heated during the winding process. If you want to apply the heat from the outside to the coiled hair, this requires an expensive and extensive device. Various attempts have also been made to generate heat inside the hair curler itself, such as that described in US Pat. No. 3,228,403. Although the results obtained with the application of heat to the interior have generally been satisfactory, these hair curler units have been difficult to use, quite large and relatively heavy, so that they are inconvenient for the user, since several are normally required Having this curler in your hair at the same time. These known hair curlers also had to be heated in boiling water for a relatively long period of time in order for them to reach their operating temperature of about 100 ⁰ O (212 ⁰ P), and thus they did not allow versatile use.

The invention is based on the object of avoiding the above disadvantages and a simple improved hair curler to create with internal heating.

The invention is based on a heated hair curling device with a self-contained tubular body around which the hair is rolled up and with a part a multi-part electrical connector at one end of the tubular body for connection to an electrical Power source.

The invention is characterized in that a heating element is contained within the outer body and is electrical one end of which is connected to one part of the electrical connection, so that the heating element is in operative connection can be brought with the electrical power source.
