Description

Die Erfindung betrifft eine Vorrichtung zur Umformung von Haaren nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for shaping hair according to the preamble of claim 1.

Zur Erzeugung von Haarwellen oder Locken werden üblicherweise einzelne feuchteTo create hair waves or curls, individual moist are usually used

Haarsträhnen auf Locken-Wickler aufgedreht, die es in vielerlei Varianten gibt. Nach dem Trocknen, gegebenenfalls unter Wärmeeinwirkung mit einer Haube, behalten dann die Haarsträhnen für eine gewisse Zeit die durch den Lockenwickler vorgegebene Form. Ein solches Verfahren ist umständlich und zeitaufwendig.Strands of hair twisted on curlers, which are available in many variations. After drying, possibly under the influence of heat with a hood, the strands of hair then retain the shape specified by the hair curler for a certain time. Such a procedure is cumbersome and time consuming.

Bei bekannten Haarformungsvorrichtungen nach dem Oberbegriff des Anspruchs 1 (DE-A-2 815 419, FR-A-2 435 925, WO 81/00347, BE-A-621 488) ist die jeweilige Heizvorrichtung ein getrenntes Bauteil, das am bzw. in der Nähe der Wandung des Haarformungskanals angebracht ist. Dadurch sind die bekannten Geräte groß und sperrig.In known hair styling devices according to the preamble of claim 1 (DE-A-2 815 419, FR-A-2 435 925, WO 81/00347, BE-A-621 488), the respective heating device is a separate component which is attached to the or is attached near the wall of the hair styling channel. As a result, the known devices are large and bulky.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Vorrichtung zum Umformen von Haaren verfügbar zu machen, bei der nicht mehr eine getrennte Heizvorrichtung für die Luft vorgesehen sein muß, so daß das Gerät kompakter werden kann. Die Lösung der Aufgabe ist im Patentanspruch 1 gekennzeichnet.The invention has for its object to provide an improved device for reshaping hair, in which a separate heating device for the air no longer has to be provided, so that the device can be more compact. The solution to the problem is characterized in claim 1.

Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. So kann die Wandung aus einem Metallrohr mit rechteckigem Querschnitt gebildet sein, in das elektrische Heizdrähte isoliert eingebettet sind. Andererseits besteht aber auch die Möglichkeit, daß die Wandung direkt als Leiter für elektrischen Strom ausgebildet ist.Developments of the invention are the subject of the dependent claims. Thus, the wall can be formed from a metal tube with a rectangular cross section, in which electrical heating wires are embedded in an insulated manner. On the other hand, there is also the possibility that the wall is designed directly as a conductor for electrical current.

Weiterhin kann vorgesehen sein, daß die Vorrichtung zur Erzeugung des Luftstroms eine am Ende des Haarformungskanals angeordnete Saugvorrichtung ist und daß die Haareinführungsöffnung den Anfang des Kanals bildet. Im einfachsten Fall kann also beispielsweise der Schlauch eines üblichen Haushaltsstaubsaugers als Saugvorrichtung dienen. Bei einer anderen Ausführungsform besteht die Vorrichtung zur Erzeugung des Luftstromes aus einem an den Anfang des Kanals angeschlossenen Gebläse, und die Haareinführungsöffnung wird durch einen Spalt in der Kanalwand gebildet. Dabei findet sich der Spalt zweckmäßig im Bereich einer düsenförmigen Verengung des Kanals, so daß ein erhöhter Unterdruck entsteht, der für ein Einsaugen der jeweiligen Haarsträhnen durch den Spalt in den Haarformungskanals sorgt.It can further be provided that the device for generating the air flow is a suction device arranged at the end of the hair-shaping channel and that the hair insertion opening forms the beginning of the channel. In the simplest case, for example, the hose of a conventional household vacuum cleaner can serve as a suction device. In another embodiment, the device for generating the air flow consists of a blower connected to the beginning of the channel, and the hair insertion opening is formed by a gap in the channel wall. The gap is expediently located in the region of a nozzle-shaped narrowing of the channel, so that an increased negative pressure is created, which ensures that the respective strands of hair are sucked in through the gap into the hair-shaping channel.

Die Querschnittsform des Haarformungskanals ist zweckmäßig etwa rechteckig mit abgerundeten Ecken. Der Kanal kann jedoch auch kreisförmigen, ovalen, quadratischen oder irgendeinen anderen gewünschten Querschnitt haben. Die Querschnittsfläche wird zweckmäßig so gewählt, daß eine übliche Haarsträhne gut einführbar ist. Damit die Vorrichtung insgesamt nicht zu groß wird, wählt man aber die Querschnittsfläche möglichst klein. Der Querschnitt wird normalerweise über die Länge des Haarformungskanals etwa konstant sein. Mit Vorteil kann jedoch vorgesehen sein, daß sich der Querschnitt zum Kanalende hin verengt. Dann steigt die Luftgeschwindigkeit zum Kanalende hin an, wodurch das Einziehen erleichtert wird.The cross-sectional shape of the hair-shaping channel is expediently approximately rectangular with rounded corners. However, the channel can also be circular, oval, square or any other desired cross section. The cross-sectional area is expediently chosen so that a normal strand of hair can be easily inserted. So that the device as a whole does not become too large, the cross-sectional area is chosen to be as small as possible. The cross section will normally be approximately constant over the length of the hair styling channel. However, it can advantageously be provided that the cross section narrows towards the end of the channel. Then the air speed increases towards the end of the canal, making it easier to pull in.

Die Innenwände des Haarformungskanals sind im allgemeinen glatt. Es besteht jedoch die Möglichkeit, im Kanal zusätzliche Formungsmittel anzubringen, beispielsweise Ausbuchtungen oder Erhöhungen, die für eine zusätzliche Struktur der Haare sorgen. Die Formungsmittel können auch aus beweglichen Teilen bestehen, beispielsweise Klappen sein, die gegebenenfalls von außen oder auch durch den Luftstrom selbst steuerbar sind.The interior walls of the hair styling channel are generally smooth. However, there is the possibility of applying additional shaping agents in the channel, for example bulges or elevations, which provide an additional structure of the hair. The shaping means can also consist of movable parts, for example flaps, which can optionally be controlled from the outside or by the air flow itself.

Wenn die Wandung des Haarformungskanals direkt als Leiter für elektrischen Strom ausgebildet ist, liefert zweckmäßig ein Transformator bei niedriger Spannung einen hohen Strom. Durch den Transformator wird gleichzeitig die aus Sicherheitsgründen erforderliche Netztrennung erreicht. Außerdem ist eine automatische Temperaturregelung oder wenigstens -begrenzung für den Luftstrom zweckmäßig.If the wall of the hair-shaping channel is designed directly as a conductor for electrical current, a transformer expediently delivers a high current at low voltage. The transformer also achieves the grid separation required for safety reasons. In addition, an automatic temperature control or at least limitation for the air flow is expedient.

Um eine Sichtkontrolle zu haben, sieht die Erfindung in ihrer weiteren Ausbildung vor, daß die Wände des Haarformungskanals wenigstens teilweise aus durchsichtigem Material bestehen. Beispielsweise kann eine Stirnwand aus durchsichtigem Kunststoff bestehen, so daß ein Einblick in die Windungen des Kanals möglich ist.In order to have a visual inspection, the invention provides in its further development that the walls of the hair-shaping channel consist at least partially of transparent material. For example, an end wall can be made of transparent plastic, so that an insight into the turns of the channel is possible.

Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen in Verbindung mit den Zeichnungen beschrieben. Es zeigen:

  • Fig. 7 schematisch die perspektivische Ansicht eines Haarformungskanals mit Rechteckquerschnitt und zugeordnetem Heizelement:
  • Fig. 8 schematisch einen Haarformungskanal mit mäanderförmigem Verlauf.
The invention is described below using exemplary embodiments in conjunction with the drawings. Show it:
  • 1 is a perspective view of an exemplary embodiment with a helical hair-shaping channel and a suction air connection;
  • Fig. 2 is an end view of the embodiment of Fig. 1;
  • 3 shows a side view of the embodiment according to FIGS. 1 and 2;
  • FIG. 4 shows a sectional view of the exemplary embodiment according to FIGS. 1 to 3 along the section line 4 - 4 in FIG. 3;

  • 7 schematically shows the perspective view of a hair styling channel with a rectangular cross section and associated heating element:
  • 8 schematically shows a hair-shaping channel with a meandering course.

Das in den Fig. 1 bis 4 dargestellte Ausführungsbeispiel der Erfindung weist eine schnecken- oder spiralförmig verlaufende Wand 1 auf, die zusammen mit Stirnwänden 2 einen schnecken- oder spiralförmigen Haarformungskanal 3 bildet. Zur Erzeugung eines Luftstromes in Richtung der Pfeile 5 ist eine der Stirnwände 2 mit einer Öffnung 6 und einem umgebenden Stutzen 7 für den Anschluß einer Saugvorrichtung, beispielsweise eines Haushaltsstaubsaugers, versehen. Die Öffnung 6 führt in das Zentrum 8 der Wand 1 und bildet das Ende des Haarformungskanals 3. Die Haareinführungsöffnung 9 stellt den Anfang des Kanals 3 dar. Zur Aufheizung des Luftstroms im Kanal 3 sind in nicht dargestellter Weise entweder in der Wand 1 elektrische Heizdrähte eingebettet, oder es wird direkt ein starker Strom mittels eines Transformators durch die Wand 1 geführt. Die Aufheizung kann auch durch Wärmeleitung von einer oder beiden Stirnwänden 2 aus erfolgen, wenn dort entsprechende Heizelemente (nicht dargestellt) vorgesehen sind.The exemplary embodiment of the invention shown in FIGS. 1 to 4 has a helical or spiral wall 1 which, together with end walls 2, forms a helical or spiral hair-shaping channel 3. To generate an air flow in the direction of arrows 5, one of the end walls 2 has an opening 6 and one surrounding nozzle 7 for the connection of a suction device, such as a household vacuum cleaner, provided. The opening 6 leads into the center 8 of the wall 1 and forms the end of the hair-shaping duct 3. The hair insertion opening 9 represents the beginning of the duct 3. To heat the air flow in the duct 3, electrical heating wires are embedded in the wall 1 in a manner not shown , or a strong current is led directly through the wall 1 by means of a transformer. The heating can also be carried out by conduction from one or both end walls 2 if corresponding heating elements (not shown) are provided there.

Bei der Anwendung wird nach Anschluß eines zu einer Saugvorrichtung führenden Schlauches an den Stutzen 7 die Haareinführungsöffnung 9 in die Nähe einer Haarsträhne gebracht, die dann durch den schneckenförmigen Kanal 5 bis ins innere gezogen und gegebenenfalls durch die Öffnung 6 austritt. Nach dem Trocknen wird die gelockte Strähne aus dem Kanal herausgezogen, wobei kurzzeitig der Luftstrom abgeschaltet wird. Es kann dann die nächste Haarsträhne behandelt werden. Zur Beschleunigung können gegebenenfalls mehrere Vorrichtungen parallel betrieben werden.In use, after connecting a hose leading to a suction device to the connector 7, the hair insertion opening 9 is brought into the vicinity of a strand of hair, which is then pulled through the helical channel 5 to the inside and optionally exits through the opening 6. After drying, the curly strand is pulled out of the channel, the air flow being switched off briefly. The next strand of hair can then be treated. If necessary, several devices can be operated in parallel for acceleration.

Das Ausführungsbeispiel gemäß Fig. 5 und 6 unterscheidet sich von dem Ausführungsbeispiel gemäß Fig. 1 bis 4 im wesentlichen dadurch, daß nicht die Luft durch die Öffnung 6 abgesaugt wird, sondern statt dessen Luft mittels eines nicht dargestellten Gebläses in Richtung des Pfeiles 10 in einen Ansatzstutzen 11 eingeblasen wird. Die Luft strömt dann wie beim Ausführungsbeispiel nach den Fig. 1 bis 4 in Richtung der Pfeile durch den Kanal 3 und wird durch die Öffnung 6 ausgeblasen. In den Kanal 3 mündet die spaltförmige Haareintrittsöffnung 12, und zwar im Bereich einer düsenförmigen Querschnittsverengung 13, die für einen höheren Unterdruck und damit ein besseres Einziehen der Haarsträhne sorgt. Die Heizung der durchströmenden Luft kann wie beim Ausführungsbeispiel gemäß Fig. 1 bis 4 erfolgen.The exemplary embodiment according to FIGS. 5 and 6 differs from the exemplary embodiment according to FIGS. 1 to 4 essentially in that it is not the air that is sucked out through the opening 6, but instead air that is blown in the direction of arrow 10 into a by means of a blower (not shown) Neck 11 is blown. The air then flows as in the embodiment of FIGS. 1 to 4 in the direction of the arrows through the channel 3 and is blown out through the opening 6. The slot-shaped hair entry opening 12 opens into the channel 3, specifically in the area of a nozzle-shaped cross-sectional constriction 13, which ensures a higher negative pressure and thus a better drawing in of the strand of hair. The air flowing through can be heated as in the exemplary embodiment according to FIGS. 1 to 4.

Fig. 7 zeigt genauer eine etwas andere Ausführungsform für einen Haarformungskanal, der durch ein Rohr 14 mit Rechteckquerschnitt und abgerundeten Ecken gebildet wird. Auf das Rohr 14 ist ein elektrisches Heizelement 15 aufgebracht, dessen Heizdrähte 16 schematisch dargestellt sind. Das Rohr 14 mit dem Heizelement 15 kann in die jeweils gewünschte Form gebogen werden, beispielsweise ebenfalls zu einer Schnecke oder Spirale, oder auch in Form eines Mäanders entsprechend der schematischen Darstellung in Fig. 8.FIG. 7 shows in more detail a somewhat different embodiment for a hair-shaping channel which is formed by a tube 14 with a rectangular cross section and rounded corners. An electrical heating element 15 is applied to the tube 14, the heating wires 16 of which are shown schematically. The tube 14 with the heating element 15 can be bent into the shape desired in each case, for example likewise into a screw or spiral, or also in the form of a meander in accordance with the schematic illustration in FIG. 8.
