Die Erfindung betrifft eine Haarbürste mit einziehbaren Borsten, umfassend einen äußeren Rohrkörper, einen innerhalb des Rohrkörpers drehbar gegenüber diesem gelagerten Borstenträger, an dem die Borsten angeschlossen sind, welcher äußere Rohrkörper Öffnungen aufweist, durch die die Borsten in ihrer Benutzungsstellung hindurchgreifen, sowie eine Aktuatoreinheit, durch die der Borstenträger gegenüber dem äußeren Rohrkörper zum Einziehen und/oder zum Ausstellen der Borsten gedreht werden kann, wobei die Aktuatoreinheit ein in axialer Richtung zur Drehachse des Borstenträgers verstellbares, durch einen Aktuator betätigbares Stellelement zum Drehen des Borstenträgers aufweist.The invention relates to a hairbrush with retractable bristles, comprising an outer tubular body, a bristle carrier mounted rotatably within the tubular body to which the bristles are connected, outer tubular bodies having openings through which the bristles pass through in their position of use, and an actuator unit, by means of which the bristle carrier can be rotated relative to the outer tubular body for drawing in and / or for exhibiting the bristles, wherein the actuator unit has an adjusting element, which can be displaced in the axial direction to the axis of rotation of the bristle carrier and can be actuated by an actuator, for rotating the bristle carrier.

Eine solche, als Aufsatz konzipierte Haarbürste ist aus EP 1 123 019 B1 bekannt. Der Aufsatz dient zum Anschließen desselben an ein Warmlufthandgerät, einen sogenannten Hairstyler. Durch diesen wird Warmluft bereitgestellt und zum Zwecke der Unterstützung einer Haarformung der Haarbürste bzw. den von dieser ergriffenen Haaren zugeführt. Derartige Haarbürsten mit einziehbaren Borsten werden eingesetzt, um zunächst mit ausgestellten Borsten eine Haarsträhne zu erfassen. Die Haarsträne wird um den äußeren Rohrkörper unter gleichzeitiger Zuführung eines Warmluftstroms gewickelt, um auf diese Weise eine Locke zu formen. Anschließend wird die noch warme Locke zur Erhöhung der Spannkraft wieder freigeben, und zwar durch Einziehen der Borsten, sodass die Haarbürste aus der geformten Locke ohne weiteres herausgezogen werden kann.Such, designed as an attachment hairbrush is off EP 1 123 019 B1 known. The attachment is used to connect it to a warm air handler, a so-called Hairstyler. Through this hot air is provided and supplied for the purpose of supporting a hair shaping of the hair brush or the hair seized by this. Such hair brushes with retractable bristles are used to first capture a strand of hair with exhibited bristles. The hair strands are wrapped around the outer tube body while supplying a stream of warm air, thereby forming a curl. Subsequently, the still warm curl to increase the clamping force release again, by retracting the bristles, so that the hair brush from the formed lock can be easily pulled out.

Diese vorbekannte Haarbürste umfasst einen äußeren Rohrkörper und einen innerhalb desselben drehbar gegenüber diesem gelagerten Borstenträger. An den Borstenträger sind die Borsten, die ihrerseits typischerweise zu Borstenreihen zusammengefasst sind, angeschlossen. Der äußere Rohrkörper verfügt über Öffnungen, durch die die Borsten in ihrer ausgestellten Stellung hindurchgreifen. Durch Drehen des Borstenträgers gegenüber dem äußeren Rohrkörper werden die Borsten eingezogen bzw. ausgestellt. Für die Zwecke einer Betätigung des Borsteneinzugs oder einer Borstenausstellung dient eine Aktuatoreinheit. Durch diese ist der Borstenträger gegenüber dem äußeren Rohrkörper drehend antreibbar. Zu diesem Zweck verfügt die Aktuatoreinheit verfügt über ein Stellelement, mit dem die Stellbewegung des Aktuators in eine drehende Antriebsbewegung zum Antreiben des Borstenträgers umgesetzt wird. Bei der aus EP 1 123 019 B1 bekannt gewordenen Haarbürste dient ein einarmiger Hebel zum Umsetzen einer in radialer Richtung ausgeführten Stellbewegung des Aktuators in eine drehende Antriebsbewegung des Bürstenträgers.This known hairbrush comprises an outer tubular body and a bristle carrier mounted rotatably within the same. At the bristle carrier, the bristles, which are in turn typically combined into bristle rows, connected. The outer tubular body has openings through which the bristles extend through in their deployed position. By rotating the bristle carrier relative to the outer tubular body, the bristles are drawn or issued. For the purposes of actuating the bristle catch or a bristle display, an actuator unit is used. Through this is the Borstenträger against the outer tubular body rotatably driven. For this purpose, the actuator unit has an adjusting element, with which the adjusting movement of the actuator is converted into a rotating drive movement for driving the bristle carrier. At the EP 1 123 019 B1 become known hairbrush is a one-armed lever for converting a running in the radial direction adjusting movement of the actuator in a rotating drive movement of the brush holder.

Aus DE 200 19 552 U1 ist eine weitere Haarbürste mit einziehbaren Borsten bekannt geworden. Diese Haarbürste ist prinzipiell aufgebaut wie die zuvor beschriebene und aus EP 1 123 019 B1 bekannt gewordene. Als Stellelement bei der in DE 200 19 552 U1 beschriebenen Haarbürste dient ein Stellelement, welches translatorisch in axialer Richtung zur Drehachse des Bürstenträgers verstellbar ist. Als Aktuator dient ein manuell betätigbarer Schwenkhebel, dessen Schwenkbewegung das Stellelement in der vorbeschriebenen axialen Richtung bewegt. Das Stellelement verfügt an seinem borstenträgerseitigen Endabschnitt über einen Kulissenantrieb, durch den die translatorische Bewegung des Stellelementes in eine Drehbewegung des Borstenträgers umgesetzt wird. Auch diese Haarbürste ist konzipiert, damit das von dieser erfasste Haar einem Warmluftstrom ausgesetzt werden kann.Out DE 200 19 552 U1 Another hairbrush with retractable bristles has become known. This hairbrush is basically constructed as the previously described and made EP 1 123 019 B1 become known. As an actuating element in the in DE 200 19 552 U1 described hairbrush serves an adjusting element which is translationally adjustable in the axial direction to the axis of rotation of the brush holder. As an actuator is a manually operable pivot lever whose pivotal movement moves the actuator in the above-described axial direction. The adjusting element has at its bristle carrier-side end portion via a link drive, by which the translational movement of the actuating element is converted into a rotational movement of the bristle carrier. This hairbrush is also designed so that the hair captured by this hair can be exposed to a stream of hot air.

Neben Haarbürsten mit einziehbaren Borsten, wie vorbeschrieben, sind auch Haarbürsten bekannt, die eine rotierende Bürste aufweisen. Ein solches Haarformgerät ist aus EP 2 074 902 B1 bekannt. Bei diesen Haarformgeräten erfolgt das Aufwickeln einer Haarsträhne durch den drehenden Antrieb des äußeren Rohrkörpers. Nachteilig bei den Haarformgeräten mit rotierender Haarbürste ist jedoch, dass diese nicht über einziehbare Borsten verfügen.In addition to hair brushes with retractable bristles, as described above, also hair brushes are known which have a rotating brush. Such a hair styling device is off EP 2 074 902 B1 known. In these hair styling devices, the winding of a strand of hair takes place by the rotating drive of the outer tubular body. A disadvantage of the hair styling devices with rotating hairbrush, however, is that they do not have retractable bristles.

Ausgehend von dem diskutierten Stand der Technik liegt der Erfindung daher die Aufgabe zugrunde, eine eingangs genannte Haarbürste dergestalt weiterzubilden, dass diese die Vorzüge einer Haarbürste mit einziehbaren Borsten mit denjenigen eines rotierenden Bürstenschaftes vereint.Based on the discussed prior art, the invention is therefore the object of developing a hairbrush mentioned above in such a way that it combines the advantages of a hair brush with retractable bristles with those of a rotating brush shaft.

Gelöst wird diese Aufgabe erfindungsgemäß durch eine eingangs genannte, gattungsgemäße Haarbürste, bei der die Haarbürste über ein Gehäuseteil mit dem Aktuator als Statoreinheit verfügt und der äußere Rohrkörper mit dem darin gelagerten Borstenträger und dem Stellelement gegenüber der Statoreinheit eine Rotoreinheit bilden, der ein drehmomentschlüssig an die Rotoreinheit angeschlossener Drehübertrager mit einem Kupplungsglied zum Empfangen einer rotatorischen Antriebsbewegung zum Antreiben der Rotoreinheit zugeordnet ist, in welchem Drehübertrager das Stellelement in einer Stellelementaufnahme translatorisch bewegbar ist, wobei zum Zwecke des translatorischen Antriebs des Stellelementes ein an das Stellelement angeschlossener, die Wandung der Stellelementaufnahme durchgreifender Mitnehmer vorgesehen ist, auf dessen außerhalb des Drehübertragers befindliches Ende die Abtriebsbewegung des statorseitigen Aktuators zum translatorischen Bewegen des Stellelements gegenüber der Stellelementaufnahme wirkt.This object is achieved according to the invention by an aforementioned, generic hairbrush, in which the hairbrush on a housing part having the actuator as a stator unit and the outer tubular body with the bristle carrier and the adjusting element mounted thereon form a rotor unit with respect to the stator unit, which is associated with a rotationally connected to the rotor unit rotary transformer with a coupling member for receiving a rotary drive movement for driving the rotor unit, in which Rotary transformer, the actuator is translationally movable in an actuator receptacle, wherein for the purpose of translational drive of the actuator connected to the actuator, the wall of the actuator element by sweeping driver is provided on the outside of the Drehübertragers befindliches end the output movement of the stator-side actuator for translational movement of the actuating element acts against the actuator element recording.

Bei dieser Haarbürste bildet der äußere Rohrkörper mit dem darin gelagerten Borstenträger samt Borsten und dem Stellelement eine Rotoreinheit, die gegenüber einem den Aktuator tragenden Gehäuseteil als Statoreinheit drehbar gegenüber dem Gehäuseteil gelagert ist. Der Rotoreinheit zugehörig ist ferner ein Drehübertrager, ausgerüstet mit einem Kupplungsglied, in das die Drehbewegung der Antriebswelle eines elektromotorischen Antriebes eingebracht wird. Der Drehübertrager verfügt über eine Stellelementaufnahme, in der das Stellelement zum Antreiben des Borstenträgers zum Zwecke des Einziehens und Ausstellens der Borsten in längsaxialer Richtung translatorisch bewegbar ist. Zum Verstellen des Stellelementes innerhalb der Stellelementaufnahme des Drehübertragers dient ein an das Stellelement angeschlossener Mitnehmer, der die Wandung der Stellelementaufnahme des Drehübertragers durchgreift. Das von der äußeren Wandung der Stellelementaufnahme des Drehübertragers abragende Ende des Mitnehmers ist somit Teil der Rotoreinheit. Auf dieses wirkt die Abtriebsbewegung des statorseitig angeordneten Aktuators. Der Mitnehmer durchgreift die Wandung der Stellelementaufnahme in einem typischerweise axial verlaufenden Bewegungsschlitz, sodass durch die Abtriebsbewegung des Aktuators über den Mitnehmer das innerhalb der Stellelementaufnahme des Drehübertragers befindliche Stellelement in axialer Richtung translatorisch bewegt werden kann. Die Aktuatoreinheit ist zu diesem Zweck konzipiert, damit die Abtriebsbewegung des Aktuators in jeder Drehstellung des Mitnehmers auf diesen für die Zwecke der Verstellung des Stellelementes wirken kann.In this hairbrush, the outer tube body with the bristle carrier mounted therein, together with bristles and the adjusting element, forms a rotor unit, which is mounted rotatably relative to the housing part in relation to a housing part carrying the actuator as a stator unit. The rotor unit is also associated with a rotary transformer, equipped with a coupling member, in which the rotational movement of the drive shaft of an electric motor drive is introduced. The rotary transformer has an actuating element receptacle, in which the actuating element for driving the bristle carrier for the purpose of drawing in and exhibiting the bristles in the longitudinal axial direction is translationally movable. For adjusting the adjusting element within the actuating element receptacle of the rotary transformer is a connected to the actuator driver, which passes through the wall of the actuating element receiving the rotary transformer. The projecting from the outer wall of the actuator element holder of the rotary transformer end of the driver is thus part of the rotor unit. On this acts the output movement of the stator side arranged actuator. The driver engages through the wall of the actuating element receptacle in a typically axially extending movement slot, so that the actuating element located within the actuating element receptacle of the rotary transmitter can be moved translationally in the axial direction by the output movement of the actuator via the driver. The actuator unit is designed for this purpose, so that the output movement of the actuator in each rotational position of the driver on this for the purposes of Adjustment of the control element can act.

Gemäß einer Ausgestaltung der Erfindung ist vorgesehen, dass der Mitnehmer an einen die Stellelementaufnahme außenseitig einfassenden Mitnehmerring angeschlossen ist, gegen den die Abtriebsbewegung des Aktuators wirkt. Ein solcher Mitnehmerring, typischerweise Teil der Rotoreinheit, hat die Funktion eines Stellflansches, gegen dessen Stirnseite unabhängig von der aktuellen Drehstellung der Rotoreinheit eine Abtriebsbewegung des Aktuators für die Zwecke einer Verstellung des Stellelementes wirken kann. In einer bevorzugten Weiterbildung dieser Ausgestaltung ist vorgesehen, dass der Mitnehmerring in einem der Statoreinheit zugeordneten Aktuatorring aufgenommen ist, und zwar dergestalt, dass der Aktuatorring gegen beide Stirnflächen des Mitnehmerringes wirkt, sodass dieser durch den Aktuatorring in beide Richtungen translatorisch bewegt werden kann. Auf den Aktuatorring wiederum wirkt der Aktuator, entweder unmittelbar oder unter Zwischenschaltung eines oder mehrerer weiterer, eine Bewegung des Aktuators übertragender Elemente, wie beispielsweise eines Untersetzungshebels.According to one embodiment of the invention, it is provided that the driver is connected to a driving ring enclosing the actuating element holder on the outside, against which the output movement of the actuator acts. Such a driver ring, typically part of the rotor unit, has the function of an adjusting flange, against the front side regardless of the current rotational position of the rotor unit can act a driven movement of the actuator for the purpose of adjusting the control element. In a preferred embodiment of this embodiment, it is provided that the driver ring is received in one of the stator associated actuator ring, in such a way that the actuator ring acts against both end faces of the driver ring, so that it can be moved translationally by the actuator in both directions. On the actuator ring, in turn, the actuator acts, either directly or with the interposition of one or more further, a movement of the actuator transmitting elements, such as a reduction lever.

Eine Ausgestaltung, wie vorbeschrieben, lässt sich mit geringem, vor allem radialem Bauraum verwirklichen, sodass sich eine solche Ausgestaltung besonders eignet, wenn durch das Gehäuseteil ein Warmluftstrom zum Unterstützen einer Haarformung gefördert werden soll. Es ist bei einer solchen Ausgestaltung zweckmäßig, wenn das Lager des Drehübertragers der Rotoreinheit über Speichen an das statorseitige Gehäuseteil angeschlossen ist.An embodiment, as described above, can be realized with little, especially radial space, so that such a configuration is particularly suitable when a hot air stream to support a hair shaping to be promoted by the housing part. It is expedient in such a configuration, when the bearing of the rotary transformer of the rotor unit is connected via spokes to the stator housing part.

Eine Übertragung der translatorischen Bewegung des in der Stellelementaufnahme des Drehübertragers angeordneten Stellelementes auf den Borstenträger erfolgt vorzugsweise mittels eines Kulissenantriebes, wie dieser aus DE 200 19 552 U1 bekannt ist, wobei durch diese explizite Bezugnahem auf dieses Dokument der Offenbarungsgehalt desselben gleichfalls zum Gegenstand der Offenbarung dieser Ausführungen gemacht wird.A transmission of the translational movement of the adjusting element arranged in the actuator of the rotary actuator control element on the bristle carrier is preferably carried out by means of a link drive, as this DE 200 19 552 U1 is known, which is made by this explicit reference to this document, the disclosure of the same also to the subject of disclosure of these statements.

Eine Haarbürste 1 ist bei dem dargestellten Ausführungsbeispiel als Aufsatz konzipiert. Die Haarbürste 1 verfügt über ein zylindrisches Gehäuseteil 2, welches an seinem in Figur 1 rechten Ende einen Kupplungsabschnitt 3 trägt, mit dem das Gehäuseteil 2 und damit die Haarbürste 1 in an sich bekannter Weise an einen Hairstyler angeschlossen werden kann. Die Haarbürste 1 verfügt des Weiteren über einen äußeren Rohrkörper 4, in den eine Vielzahl, jeweils in Reihen angeordnete Öffnungen 5 eingebracht sind. Weiteres Teil der Haarbürste 1 sind mehrere Borstenreihen 6 deren einzelne Borsten B in der in Figur 1 gezeigten ausgestellten Stellung Öffnungen 5 des äußeren Rohrkörpers 4 durchgreifen. Das Gehäuseteil 2 weist einen größeren Durchmesser auf als der äußere Rohrkörper 4. In die zu dem äußeren Rohrkörper 4 weisende Stirnseite des Gehäuseteils 2 sind mehrere Durchbrechungen 7 eingebracht. Diese dienen zum Auslassen eines durch den Kupplungsabschnitt 3 in die Haarbürste 1 bzw. in den Gehäuseteil 2 eingeleiteten Warmluftstroms. Zum Auslassen des eingeleiteten Warmluftstroms dienen ebenfalls die Öffnungen 5, vor allem die Öffnungen, durch die keine Borsten B hindurchgreifen.A hairbrush 1 is designed as an attachment in the illustrated embodiment. The hairbrush 1 has a cylindrical housing part 2, which at its in FIG. 1 right end carries a coupling portion 3, with which the housing part 2 and thus the hair brush 1 can be connected in a conventional manner to a Hairstyler. The hairbrush 1 furthermore has an outer tubular body 4, into which a multiplicity of openings 5, each arranged in rows, are introduced. Another part of the hairbrush 1 are several rows of bristles 6 whose individual bristles B in the in FIG. 1 shown exhibited position openings 5 of the outer tubular body 4 pass through. The housing part 2 has a larger diameter than the outer tubular body 4. In the facing to the outer tube body 4 end face of the housing part 2 a plurality of openings 7 are introduced. These are used for discharging a introduced through the coupling portion 3 in the hair brush 1 and in the housing part 2 hot air flow. To omit the initiated Warm air flow are also the openings 5, especially the openings through which no bristles B reach through.

Der äußere Rohrkörper 4 mit den Borstenreihen 6 ist gegenüber dem Gehäuseteil 2 drehbar, wie dieses nachstehend beschrieben ist. An dem Gehäuseteil 2 ist als Aktuator ein Schwenkhebel 8 gelagert. Die Schwenkachse des Schwenkhebels 8 ist in Figur 1 mit dem Bezugszeichen 9 gekennzeichnet. Durch Betätigen des Schwenkhebels 8 in Richtung zum Gehäuseteil 2 hin können die Borsten B in den äußeren Rohrkörper 4 eingezogen werden.The outer tube body 4 with the rows of bristles 6 is rotatable relative to the housing part 2, as described below. On the housing part 2, a pivot lever 8 is mounted as an actuator. The pivot axis of the pivot lever 8 is in FIG. 1 designated by the reference numeral 9. By pressing the pivoting lever 8 in the direction of the housing part 2, the bristles B can be drawn into the outer tubular body 4.

Die Borstenreihen 6 sind in an sich bekannter Weise an einen innerhalb des äußeren Rohrkörpers 4 drehbar gelagerten Borstenträger 10 angeschlossen, von dem in Figur 2 der in das Gehäuseteil 2 hineinreichende Abschnitt desselben erkennbar ist. Der Einfachheit halber ist der äußere Rohrkörper 4 in Figur 2 nicht gezeigt, ebensowenig wie das Gehäuseteil 2. Der Borstenträger 10 ist zusammen mit dem äußeren Rohrkörper 4 gegenüber dem Gehäuseteil 2 drehbar. Mithin bilden diese Komponenten eine Rotoreinheit. Demgegenüber bildet das Gehäuseteil 2 mit dem Schwenkhebel 8 eine Statoreinheit.The bristle rows 6 are connected in a conventional manner to a rotatably mounted within the outer tubular body 4 bristle carrier 10, from the in FIG. 2 the reaching into the housing part 2 section thereof is recognizable. For the sake of simplicity, the outer tubular body 4 is in FIG. 2 not shown, as well as the housing part 2. The bristle carrier 10 is rotatable relative to the housing part 2 together with the outer tubular body 4. Thus, these components form a rotor unit. In contrast, the housing part 2 forms a stator unit with the pivot lever 8.

Zum Übertragen einer Drehbewegung auf die Rotoreinheit dient ein Drehübertrager 11. Der Drehübertrager 11 verfügt als weiterer Teil der Rotoreinheit über eine Rohraufnahme 12, in der der äußere Rohrkörper 4 drehmomentschlüssig mit seinem Endabschnitt eingreift. An dem der Rohraufnahme 12 gegenüber liegenden Ende verfügt der Drehübertrager 11 über ein Kupplungsglied 13 zum Empfangen einer Drehbewegung. Ist die Haarbürste 1 auf einen Hairstyler aufgesetzt, wird durch den Vorgang des Aufsetzens das Kupplungsglied 13 auf eine elektromotorisch angetriebene Antriebswelle des Hairstylers aufgesetzt, sodass der Drehübertrager und damit die gesamte Rotoreinheit der Haarbürste 1 durch den hairstylerseitigen Elektromotor drehend antreibbar ist. Der Drehübertrager 11 verfügt über einen rohrzylindrischen Abschnitt 14, in dem in einer Stellelementaufnahme ein längliches Stellelement 15 aufgenommen ist. Das Stellelement 15 ist in dem Abschnitt 14, der innenseitig die Stellelementaufnahme darstellt, in längsaxialer Richtung hin- und herbewegbar. Als Führung des Stellelementes 15 dienen zwei einander diametral gegenüber liegende Führungszapfen 16, von denen in Figur 2 nur der obere Führungszapfen 16 erkennbar ist. Der Führungszapfen 16 greift ein in einen Stellschlitz 17 des Abschnittes 14 des Drehübertragers 11. Zum Übertragen einer durch axiales Bewegen ausgeübten translatorischen Bewegung des Stellelementes 15 auf den Borstenträger 10 verfügt das Stellelement 15 an seinem zu dem Borstenträger 10 weisenden Endabschnitt über einen Kulissenantrieb 18. Bei dem dargestellten Ausführungsbeispiel ist in das Stellelement 15 an seinem zu dem Borstenträger 10 weisenden Ende eine schraubenlinienförmige Stellkulisse 19 eingebracht. Ein Stellstift 20 greift in die Stellkulisse 19 des Stellelementes 15 ein und ist seinerseits in einer den Bürstenträger 10 durchgreifenden Bohrung 21 gehalten. Damit ist der Stellstift 20 dem Bürstenträger 10 zugeordnet und somit ortsfest in Bezug auf die längsaxiale Bewegung des Stellelementes 15 gehalten. Bei einer längsaxialen Bewegung des Stellelementes 15 wird der Stellstift 20 entlang der schraubenlinienförmigen Kulisse 19 bewegt und infolge der drehbaren Lagerung des Bürstenträgers 10 gegenüber dem äußeren Rohrkörper 4 und dem Stellelement 15 entsprechend gedreht. Im Zuge dieser Drehung werden die Borstenreihen 6 in an sich bekannter Weise verschwenkt und in das äußere Rohr 4 eingezogen.To transmit a rotary motion to the rotor unit is a rotary transformer 11. The rotary transformer 11 has as a further part of the rotor unit via a pipe receiving 12 in which the outer tubular body 4 engages torque-locking with its end portion. At the end of the pipe receiving 12 opposite end of the rotary transformer 11 has a coupling member 13 for receiving a rotational movement. If the hairbrush 1 is placed on a hairstyler, the coupling member 13 is placed on an electric motor driven drive shaft of the Hairstylers by the process of placing, so that the rotary transformer and thus the entire rotor unit of the hair brush 1 is rotationally driven by the hairstyler side electric motor. The rotary transformer 11 has a tubular cylindrical section 14, in which an elongate adjusting element 15 is accommodated in an actuating element receptacle. The actuator 15 is in the section 14, which is the inside of the actuator receptacle, back and forth in the longitudinal axial direction. As a guide of the actuating element 15 serve two diametrically opposite lying guide pins 16, of which in FIG. 2 only the upper guide pin 16 can be seen. To transmit a force exerted by axial movement translational movement of the actuating element 15 on the bristle carrier 10, the actuator 15 has at its pointing to the bristle carrier 10 end portion via a link drive 18th Bei. The guide pin 16 engages a slot 17 of the section 14 In the illustrated embodiment, a helical Stellkulisse 19 is introduced into the actuator 15 at its pointing to the bristle carrier 10 end. An adjusting pin 20 engages in the adjusting link 19 of the actuating element 15 and in turn is held in a bore 21 which passes through the brush carrier 10. Thus, the adjusting pin 20 is associated with the brush holder 10 and thus held stationary with respect to the longitudinal axial movement of the actuating element 15. In a longitudinal axial movement of the actuating element 15 of the adjusting pin 20 is moved along the helical link 19 and rotated accordingly due to the rotatable mounting of the brush holder 10 relative to the outer tubular body 4 and the adjusting element 15. In the course of this rotation, the bristle rows 6 are pivoted in a conventional manner and pulled into the outer tube 4.

Zum Bewegen des Stellelementes 15 zum Einziehen der Bürsten B dient ein in Figur 2 nicht dargestellter Mitnehmerstift, der eine Mitnehmerbohrung 22 des Stellelementes 15 und den Stellschlitz 17 des Drehübertragers 11 durchgreift. Die über die äußere Mantelfläche des die Stellelementaufnahme bildenden Abschnittes 14 hinausragenden Abschnitte des Mitnehmers greifen in einen auf der Außenseite des Abschnittes 14 in längsaxialer Richtung verstellbaren Mitnehmerring 23, wie dieses besser aus der Schnittdarstellung der Figur 3 erkennbar ist. Der in Figur 2 nicht dargestellte Mitnehmerstift ist in Figur 3 mit dem Bezugszeichen 24 gekennzeichnet. Der Mitnehmerring 23 ist seinerseits aufgenommen in einem aus zwei Ringteilen 25, 25.1 gebildeten Aktuatorring 26. Der Aktuatorring 26 ist im Unterschied zu dem Drehübertrager 11 mit seinem Mitnehmerring 23 Teil der Statoreinheit. Das Ringteil 25 des Aktuatorringes 26 trägt ein radial abragendes Anschlussstück 27, auf welches die Abtriebsbewegung des Schwenkhebels 8 wirkt, und zwar dergestalt, dass eine Betätigung des Schwenkhebels 8 in Richtung zu dem Gehäuseteil 2 zu einer axialen Verschiebebewegung des Aktuatorringes 26 führt. Da der Mitnehmerring 23 formschlüssig in dem Aktuatorring 26 in axialer Richtung aufgenommen ist, wird dieser von dem Aktuatorring 26 mitgenommen. Durch den Mitnehmerring 23 wird der Mitnehmerstift 24 und damit das Stellelement 15 entsprechend mitbewegt. Die Folge einer solchen Betätigung ist, wie vorstehend beschrieben, eine Drehbewegung des Borstenträgers 10.To move the adjusting element 15 for drawing in the brush B is used in FIG. 2 not shown drive pin, which passes through a driver bore 22 of the actuating element 15 and the adjusting slot 17 of the rotary transformer 11. The projecting beyond the outer circumferential surface of the actuating element receiving portion 14 portions of the driver engage in an adjustable on the outside of the portion 14 in the longitudinal axial direction carrier ring 23, as this better from the sectional view of FIG. 3 is recognizable. The in FIG. 2 not shown driving pin is in FIG. 3 designated by the reference numeral 24. The driver ring 23 is in turn received in an actuator ring 26 formed from two ring parts 25, 25.1. The actuator ring 26 is in contrast to the rotary transformer 11 with its driver ring 23 part of the stator. The ring member 25 of the actuator ring 26 carries a radially projecting connection piece 27, on which the output movement of the pivot lever 8 acts, in such a way that an actuation of the pivot lever 8 leads in the direction of the housing part 2 to an axial displacement movement of the actuator ring 26. Since the Mitnehmerring 23 is positively received in the actuator ring 26 in the axial direction, this is taken from the actuator ring 26. Through the driver ring 23 of the driver pin 24 and thus the actuator 15 is moved accordingly. The result of such an operation, as described above, a rotational movement of the bristle carrier 10th

Es versteht sich, dass der Mitnehmerring 23, der Mitnehmerstift 24 zusammen mit dem Drehübertrager 18 und dem Stellelement 15 neben dem Borstenträger 10 und dem äußeren Rohrkörper 4 Teil der Rotoreinheit sind. Der den Mitnehmerring 23 einfassende Aktuatorring 26 ist dagegen Teil der Statoreinheit.It is understood that the driving ring 23, the driving pin 24 together with the rotary transformer 18 and the adjusting element 15 next to the bristle carrier 10 and the outer tubular body 4 are part of the rotor unit. By contrast, the actuator ring 26 enclosing the driver ring 23 is part of the stator unit.

Das Zusammenwirken der zuvor beschriebenen Komponenten ist aus den Schnittdarstellungen der Figuren 3 und 4 ersichtlich. Bei dem dargestellten Ausführungsbeispiel ist der Schwenkhebel 8 unter Zwischenschaltung eines Untersetzungshebels 28 an das Anschlussstück 27 des Aktuatorringes 26 angeschlossen. Eine Stellbewegung des Schwenkhebels 8 erfolgt gegen die Rückstellkraft einer Schraubendruckfeder 29. Die Bewegungsrichtung des Aktuatorringes 26 ist in Figur 3 durch einen Pfeil kenntlich gemacht, ebenso wie die Schwenkbewegung des Stellhebels 8 zum Durchführen der Aktuatorringbewegung. Während Figur 3 die Haarbürste 1 mit ausgestellten Borsten B zeigt, zeigt Figur 4 die Haarbürste 1 nach Betätigen des Schwenkhebels 8 mit eingezogenen Borsten B. Erkennbar ist die äußere Oberfläche des äußeren Rohrkörpers 4 frei von ausgestellten Borsten oder Borstenenden, sodass dieser Stellung der äußere Rohrkörper 4 aus einer Locke ohne weiteres herausgezogen werden kann. Durch die Schwenkbewegung des Stellhebels 8 ist der Aktuatorring 26 in Richtung zum äußeren Rohrkörper 4 bewegt worden und mit diesem der Mitnehmerstift 24 sowie das Stellelement 15. Durch Einschieben des Stellstiftes 20 in die Stellkulisse 19 ist der Borstenträger 10 zum Einziehen der Borsten B bewegt worden. Die Mitnahme des Mitnehmerringes 23 erfolgt durch die formschlüssige Aufnahme des Mitnehmerringes 23 in dem Aktuatorring 26. Wird der Stellhebel 8 losgelassen, wird dieser durch die in der Schraubendruckfeder 29 gespeicherte Energie zurückgestellt und demzufolge wird auch der Aktuatorring 26 wieder in die in Figur 3 gezeigte Stellung zurückbewegt und mit diesem das Stellelement 15. Da gegenüber dem Stellelement 15 der Borstenträger 10 in längsaxialer Richtung feststehend, gegenüber dem äußeren Rohr 4 und dem Stellelement 15 jedoch drehbar gelagert ist, wird durch diese Bewegung der Borstenträger 10 in die andere Richtung gedreht, sodass die Borsten B wieder ausgestellt werden.The interaction of the components described above is from the sectional views of FIGS. 3 and 4 seen. In the illustrated embodiment, the pivot lever 8 is connected with the interposition of a reduction lever 28 to the connector 27 of the actuator ring 26. An actuating movement of the pivot lever 8 takes place against the restoring force of a helical compression spring 29. The direction of movement of the actuator ring 26 is in FIG. 3 indicated by an arrow, as well as the pivotal movement of the actuating lever 8 for performing the Aktuatorringbewegung. While FIG. 3 the hairbrush 1 with flared bristles B shows shows FIG. 4 the hair brush 1 after pressing the pivot lever 8 with retracted bristles B. Visible, the outer surface of the outer tube body 4 is free of flared bristles or bristle ends, so that this position of the outer tube body 4 can be pulled out of a lock easily. By the pivotal movement of the actuating lever 8, the actuator ring 26 has been moved in the direction of the outer tube body 4 and with this the driver pin 24 and the actuator 15. By inserting the adjusting pin 20 in the adjusting link 19, the bristle carrier 10 has been moved to retract the bristles B. If the actuating lever 8 is released, this is reset by the energy stored in the helical compression spring 29 and consequently the actuator ring 26 is again in the in FIG. 3 shown moved back position and with this the actuator 15. Since opposite the actuator 15 of the bristle carrier 10 in the longitudinal axial direction fixed, but is rotatably mounted relative to the outer tube 4 and the actuator 15, is rotated by this movement of the bristle carrier 10 in the other direction, so that the bristles B are issued again.

Der Drehübertrager 11 ist mittels Speichen S an die Innenwand des Gehäuseteils 2 angeschlossen. Dabei verbleibt ein ausreichender Hohlraum, damit von einem an die Haarbürste 1 angeschlossenen Hairstyler Warmluft durch die Aktuatoreinheit hindurchtreten kann.The rotary transformer 11 is connected by means of spokes S to the inner wall of the housing part 2. In this case, a sufficient cavity remains so that hot air can pass through the actuator unit from a hair styler connected to the hairbrush 1.

Zusätzliche Öffnungen in der Rohraufnahme 12 des Drehübertragers 11 dienen dem Zweck, dass ein Teil des in das Gehäuseteil 2 eingebrachten Warmluftstromes in das Innere des äußeren Rohrkörpers 4 eintreten kann.Additional openings in the tube receptacle 12 of the rotary transformer 11 serve the purpose that a portion of the introduced into the housing part 2 hot air flow can enter into the interior of the outer tubular body 4.
