Description

Die Erfindung betrifft eine Styling- und Curlinghaarbürste mit einem langgestreckten, rohrförmigen Körper, dessen innerer, der Längserstreckung des Körpers folgender Hohlraum einen nach Art eines Sammlers ausgebildeten und über sein offenes Ende mit einem Warmluftstrom beaufschlagbaren Luftkanal darstellt und in den den Luftkanal mit der äußeren Mantelfläche des rohrförmigen Körpers verbindende Luftaustrittsöffnungen eingebracht sind, mit mehreren, bezüglich des rohrförmigen Körpers umfänglich verteilt angeordneten Borstenreihen und mit einem anströmseitig vor den Borstenreihen vorgesehenen Luftstromteiler, durch den ein zugeführter Warmluftstrom in einen in den Luftkanal des rohrförmigen Körpers einströmenden und in einen an der äußeren Mantelfläche des rohrförmigen Körpers entlang strömenden Luftstrom geteilt wird, wobei die Borsteureihen der Bürste jeweils mit Abstand Zweinander angeordnet sind.The invention relates to a styling and Curlinghaarbürste with an elongated, tubular body, its inner, the longitudinal extent the body following cavity one formed in the manner of a collector and be acted upon by its open end with a stream of hot air Representing air duct and in the air duct with the outer Outer surface of the tubular body connecting air outlet openings are introduced, with a plurality, with respect to the tubular body arranged circumferentially arranged rows of bristles and with an upstream side provided before the rows of bristles air flow divider, through the one supplied hot air flow in a in the air duct of the tubular Body inflowing and into one on the outer surface of the tubular body is divided along flowing air flow, wherein the bristle rows of the brush each with distance Are arranged in two.

Mit derartigen Haarbürsten siehe z.B. US4250902 A kann Haar geformt werden, wobei durch die über den Warmluftstrom zugeführte Wärme der Haarformprozess unterstützt wird. Eine solche Haarbürste umfasst mehrere Borstenreihen, die gleichmäßig zueinander von einem langgestreckten rohrförmigen Körper radial abstehend angeordnet sind. Die Borstenreihen können gebildet sein durch einzelne Borstenelemente aus Kunststoff oder Stahl oder etwa durch Borstenbüschel. Die einzelnen Borstenreihen sind der Längserstreckung des rohrförmigen Körpers folgend angeordnet. Zwischen den einzelnen Borstenreihen sind den rohrförmigen Körper durchbrechende Öffnungen vorgesehen, aus denen bei Beaufschlagung des inneren Luftkanals des rohrförmigen Körpers mit einem Warmluftstrom Warmluft austritt. Um den zu formenden Haaren mehr Wärme zukommen zu lassen, sich jedoch aufgrund der gewünschten engständigen Anordnung der einzelnen Borsten eine weitere Perforation des rohrförmigen Körpers verbietet, sind Styling- und Curlinghaarbürsten entwickelt worden, bei denen ebenfalls ein an der Mantelfläche des rohrförmigen Körpers entlangströmender Luftstrom vorgesehen ist. Zu diesem Zweck verfügt eine solche Haarbürste über einen Luftstromteiler, um einen Teil des die Haarbürste beaufschlagenden Warmluftstroms auf die Außenseite des rohrförmigen Körpers zu lenken. Dieser Luftstrom durchströmt die einzelnen Borsten bzw. Borstenreihen im Bereich ihres Ansatzes.With such hairbrushes see, e.g. US4250902A can be shaped by the hair Heat supplied via the hot air flow supports the hair styling process becomes. Such a hairbrush comprises several bristle rows, the evenly apart from an elongate tubular body are arranged radially projecting. The bristle rows can be formed by individual bristle elements made of plastic or steel or about through bristle tufts. The individual rows of bristles are the longitudinal extent arranged following the tubular body. Between individual rows of bristles are breaking through the tubular body Openings provided from which when exposed to the inner air duct of the tubular body with a hot air stream warm air emerges. To give more heat to the hair to be formed, However, due to the desired close arrangement of the individual Bristles prohibits further perforation of the tubular body, Styling and curling hairbrushes have been developed in which also a flowing along the lateral surface of the tubular body Air flow is provided. For this purpose has such Hairbrush via an airflow divider to a part of the hairbrush impinging hot air flow to the outside of the tubular To steer the body. This air flow flows through the individual bristles or bristle rows in the area of their approach.

Bei einer Benutzung einer solchen Styling- und Curlinghaarbürste ist jedoch festzustellen, dass zwar diejenigen Haare, die sich im Bereich der Austrittsöffnungen, durch die der äußere Luftstrom austritt besser geformt werden als diejenigen, die von diesen Luftaustrittsöffnungen entfernt angeordnet sind. Begründet liegt dies darin, dass die im Nahbereich zu den Luftaustrittsöffnungen befindlichen und bei einer Benutzung der Haarbürste um die Haarbürste gewickelten Haare von dem aus diesen Luftaustrittsöffnungen austretenden Luftstrom angeströmt sind, jedoch gleichfalls der Weg des Luftstromes zu den entfernter befindlichen Haaren bzw. Haarbüscheln durch die Haare versperrt ist. Auch wenn es mitunter gewünscht sein kann, über die Nutzlänge einer solchen Haarbürste bei gleichen Formvorgang ein unterschiedliches Formergebnis zu erzielen, wäre es jedoch wünschenswert, eine Styling- und Curlinghaarbürste zur Verfügung zu haben, bei der über die gesamte Nutzlänge ein gleiches Formergebnis erzielt werden kann.However, using one such styling and curling hairbrush is to determine that, although those hairs that are in the field of Outlet openings through which the outer airflow emerges better shaped are considered to be the ones that are located away from these air vents are. This is due to the fact that in the vicinity of the Air outlet openings located and when using the hairbrush Hair wrapped around the hairbrush from the hair from these air vents exiting air flow have flowed, however likewise the path of the air stream to the hairs further away or hair tufts is blocked by the hair. Even if it sometimes may be desired over the useful length of such a hairbrush at same molding process to achieve a different shape result However, it would be desirable to have a styling and curling hairbrush for To have available at the same over the entire useful length Form result can be achieved.

Daher liegt ausgehend von dem diskutierten Stand der Technik der Erfindung die Aufgabe zugrunde, eine eingangs genannte, gattungsgemäße Styling- und Curlinghaarbürste vorzuschlagen, mit der die zu dem diskutierten Stand der Technik aufgezeigten Nachteile zumindest weitestgehend vermieden sind.Therefore, starting from the discussed prior art of the invention the object of an initially mentioned, generic To propose styling and curling hairbrush with which to discuss the State of the art pointed disadvantages at least as far as possible are avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die einzelnen Borstenreihen durch jeweils ein in radialer Richtung geschlossenes und jeweils zumindest einen Luftströmungskanal ausbildendes, zumindest zu einer benachbarten Borstenreihe hin offenes oder mit Öffnungen versehenes Luftführungselement angeordnet ist.This object is achieved in that the individual bristle rows by a respective closed in the radial direction and each forming at least one air flow channel, at least to a neighboring row of bristles open or with openings provided air guide element is arranged.

Bei dieser Styling- und Curlinghaarbürste sind die Borstenreihen mit Abstand zueinander angeordnet. Eine Borstenreihe im Rahmen dieser Ausführungen kann aus einer einzelnen Reihe gebildet sein; eine Borstenreihe im Sinn dieser Beschreibung kann jedoch auch durch mehrere parallel und/oder versetzt zueinander angeordnete Borstenreihen gebildet sein. In jedem Fall sind die Borstenreihen bzw. die Borstenreihenanordnungen gruppiert umfänglich zu dem rohrförmigen Körper angeordnet, wobei jede Gruppe einen Abstand zur benachbarten Gruppe aufweist. Zwischen jeder Borstenreihe ist ein Luftführungselement angeordnet, das parallel zu den Borstenreihen und somit zur Längserstreckung des rohrförmigen Körpers folgend angeordnet ist. Jedes Luftführungselement bildet einen in radialer Richtung geschlossenen Luftströmungskanal aus. Ein solcher Luftströmungskanal ist in radialer Richtung geschlossen, jedoch zu zumindest einer benachbarten Borstenreihe hin offen oder in dieser Richtung mit Öffnungen versehen. Der in radialer Richtung hin wirkende Abschluss des Luftführungselementes bildet einen von dem rohrförmigen Körper beabstandet gehaltenes Leitblech, unter dem ein Mantelluftstrom transportiert werden kann. Dabei dient das Leitblech eines jeden Luftführungselementes nicht nur zum Leiten eines Teilmantelluftstromes sondern auch dem Zweck, den durch die Luftführungselemente gebildeten Strömungskanal bei einer Benutzung der Haarbürste offen zu halten. In einen solchen, seitlich offenen Luftführungskanal können sich bei einer Benutzung der Bürste auch bei intensivem Eindrehen derselben in die zu formenden Haare keine Haare einlegen. Um den rohrförmigen Körper sind mehrere derartiger Luftführungselemente angeordnet. Daher können sich bei dieser Bürste bei ihrer Benutzung auch keine Haare bis in den Fuß der Borstenreihen einrollen. Somit werden nicht nur die eigentlichen, von den Luftführungselementen gebildeten Strömungskanäle sondern auch der Ansatz der Borstenreihen freigehalten. Aus diesem Grunde kann auch ein die Borstenreihen unmittelbar beaufschlagender Mantelluftstrom bei einer Benutzung der Haarbürste unter den mit Abstand zur äußeren Mantelfläche des rohrförmigen Körpers gehaltenen Haaren entlangströmen und die mitgeführte Wärme an die Haare abgeben. Dabei stellt derjenige Mantelteilluftstrom, der in dem durch jeweils ein Luftführungselement gebildeten Strömungskanal transportiert wird, ein Wärmereservoir dar, damit auch die im Bereich des freien Endes der Nutzfläche der Bürste befindlichen Haare einen ausreichenden Wärmezustrom erhalten. Die durch die Luftführungselemente gebildeten Strömungskanäle sind in einem Ausführungsbeispiel an ihrem freien Ende oder im Bereich ihres freien Endes verschlossen, so dass aufgrund der auftretenden Wirbel eine Wärmeübertragung von dem Luftstrom auf die Haare begünstigt ist.In this styling and Curlinghaarbürste the bristle rows are at a distance arranged to each other. A row of bristles in the context of these designs may be formed from a single row; a row of bristles in the sense of this description, however, can also be parallel through several and / or staggered rows of bristles may be formed. In In any case, the bristle rows or rows of bristles are arranged circumferentially arranged to the tubular body, each Group has a distance to the neighboring group. Between everyone Bristle row is arranged an air guide element, which is parallel to the Bristle rows and thus to the longitudinal extent of the tubular body is arranged following. Each air guide element forms a radial Direction closed air flow channel. Such an air flow channel is closed in the radial direction, but at least an adjacent row of bristles open or in this direction with Provided openings. The acting in the radial direction conclusion of the Air guide element forms a spaced from the tubular body held baffle under which transported a shell airflow can be. The baffle of each air guide element serves not only for guiding a partial jacket air flow but also the Purpose, the flow channel formed by the air guide elements to keep it open when using the hairbrush. In such, laterally open air duct can be when using the Brush even with intense screwing the same in the forming Hair does not have hair. To the tubular body are several arranged such air guide elements. Therefore, at this Do not brush hair into the foot of bristle rows when using it roll up. Thus, not only the actual, of the Air ducting formed flow channels but also the Approach of the bristle rows kept free. For this reason can also be a the bristle rows directly acting Mantelluftstrom at a Use the hairbrush under the distance from the outer surface flowing along the tubular body held hair and the give off heat to the hair. In this case, the one shell air flow, in the formed by in each case an air guide element Flow channel is a heat reservoir, so too located in the region of the free end of the effective area of the brush Hair received a sufficient heat flow. The through the air guide elements formed flow channels are in one embodiment at their free end or in the area of their free end closed, so that due to the vortex occurring a heat transfer is favored by the air flow on the hair.

Zusätzlich und unterstützend zu diesem der Längserstreckung des rohrförmigen Körpers der Bürste folgenden Mantelluftströme tritt aus dem Inneren des rohrförmigen Körpers an entsprechenden Luftaustrittsöffnungen ebenfalls Warmluft aus, wodurch der Mantelluftstrom nicht nur einen zu den zu formenden Haaren gerichtete Ablenkung erfährt, sondern durch die erzeugten Turbulenzen einen Wärmeübergang im Bereich der Borstenreihen begünstigt ist.In addition and supporting to this the longitudinal extension of the tubular Body of the brush following sheath air streams emerges from the interior the tubular body at corresponding air outlet openings also hot air, whereby the shell air flow not only a to the hair to be formed deflection directed, but by the turbulence generated heat transfer in the bristle rows is favored.

In einem bevorzugten Ausführungsbeispiel sind die Luftführungselemente aus Metall, beispielsweise aus Aluminium hergestellt. Diese Elemente speichern bei einer Benutzung der Bürste Wärme, die über die Außenseite der Luftführungselemente an die daran anliegenden Haare abgegeben wird. Somit dienen die Luftführungselemente nicht nur zum Leiten eines Mantelluftstromes bzw. zum Leiten von Mantelteilluftströmen sondern ebenfalls zum Ausbilden von wärmeplattenartigen Elementen.In a preferred embodiment, the air guide elements made of metal, for example made of aluminum. These elements When using the brush, store heat over the outside the air guide elements delivered to the adjoining hair becomes. Thus, the air guide elements are not only for guiding a jacket air flow or for the conduction of jacket side air streams but also for forming heat plate-like elements.

Die radial nach außen weisenden Abschlüsse der Luftführungselemente bilden bevorzugt eine geschlitzte Hülse aus, wobei in den geschlitzten Bereichen jeweils eine Borstenreihe angeordnet ist. Die Luftführungselemente können unterschiedlich ausgestaltet sein. Bei einer Ausgestaltung, bei dem ein solches Luftführungselement im wesentlichen zu einer benachbarten Borstenreihe hinweisend geöffnet ist, ist dieses O-förmig ausgestaltet und entsprechend der Krümmung der äußeren Mantelfläche des rohrförmigen Körpers gekrümmt. Ebenfalls kann vorgesehen sein, dass die Luftführungselemente zwar in radialer Richtung geschlossen, jedoch zu beiden benachbarten Borstenreihen hin geöffnet sind. Ein solches Luftführungselement ist dann im Querschnitt T-förmig ausgebildet. Ein solches Luftführungselement bildet sodann zwei Strömungskanäle aus.The radially outwardly facing terminations of the air guide elements Preferably form a slotted sleeve, wherein in the slotted areas in each case a row of bristles is arranged. The air guiding elements can be configured differently. In one embodiment, in which such an air guide element substantially to an adjacent Bristle row hinweisend is open, this is designed O-shaped and according to the curvature of the outer surface of the curved tubular body. It can also be provided that Although the air guide elements closed in the radial direction, however are open to both adjacent bristle rows. Such Air guide element is then T-shaped in cross section. One Such air guide element then forms two flow channels.

Die Borstenreihen und ebenso die Luftführungselemente der Styling- und Curlinghaarbürste können der Längserstreckung des rohrförmigen Körpers folgend gerade verlaufend ausgebildet sein. Diese können jedoch auch nach Art einer Spirale den rohrförmigen Körper umgebend angeordnet sein.The bristle rows and also the air guiding elements of the styling and Curling hairbrush can be the longitudinal extent of the tubular body following straight to be trained. These can, however arranged also surrounding the tubular body in the manner of a spiral be.

Der Styling- und Curlinghaarbürste kann ein in einem Griff angeordnetes Warmluftgebläse zugeordnet sein. Gleichfalls ist es möglich, diese Haarbürste mit einem Kupplungsstück auszubilden, um diese als Aufsatz auf einen Handgriff mit einem Warmluftgebläse aufsetzen zu können. Das Warmluftgebläse kann dann auch für andere Haarformaufsätze eingesetzt werden.The styling and Curlinghaarbürste can be arranged in a handle Hot air blower be assigned. It is also possible to use this hairbrush form with a coupling piece to this as an attachment to put on a handle with a hot air blower. The Hot air blower can then be used for other hair styling attachments become.

Der innere, an dem Rohr 6 anliegende Abschnitt der Hülse 11 stellt somit bezüglich des Rohrs 6 einen Mantel mit den selben Eigenschaften wie das Rohrs 6 dar, so dass die Luftaustrittsöffnungen 9 ebenfalls die Hülse 11 durchgreifen und die Hülse 11 die Öffnungen 8 zum Durchlassen der Borstenbüschel aufweist.Placed on the tube 6 and rotatably connected to this in the illustrated embodiment, three air guide elements L 1 , L 2 , L 3 supporting sleeve 11. The inner, applied to the pipe section 6 of the sleeve 11 thus provides with respect to the tube 6 a sheath with the same characteristics as the tube 6, so that the air outlet openings 9 also pass through the sleeve 11 and the sleeve 11 has the openings 8 for the passage of the bristle tufts.

Im Folgenden ist das Luftführungselement L1 näher beschrieben; die beiden weiteren Luftführungselemente L2 und L3 sind entsprechend aufgebaut. Das Luftführungselement L1 schließt einen gekrümmten, U-förmigen Strömungskanal 12 ein, der in radialer Richtung zum Rohr 6 durch den äußeren Abschluss 13 des Luftführungselementes L1 geschlossen ist. Dieser äußere Abschluss 13 des Luftführungselementes L1 übernimmt die Funktion eines Leitbleches. Der äußere Abschluss ist über einen Steg 14 mit dem das Rohr 6 einschließenden Mantel der Hülse 11 verbunden. Der äußere Abschluss 13 ist entsprechend seines Abstandes zur Mantelfläche des Rohres 6 und entsprechend seiner konzentrischen Anordnung zu dem Rohr 6 gekrümmt. Der vordere Abschluss 15 ist ebenso wie die Anbindung des Steges 14 an den Abschluss 13 gerundet ausgebildet, insbesondere um Beschädigungen an dem zu formenden Haar zu vermeiden. Der durch das Luftführungselement L1 gebildete Strömungskanal 12 ist in tangentialer Richtung und somit zur Borstenreihe B1 hin offen.In the following, the air guide element L 1 is described in detail; the two other air guide elements L 2 and L 3 are constructed accordingly. The air guide element L 1 includes a curved, U-shaped flow channel 12, which is closed in the radial direction to the tube 6 through the outer end 13 of the air guide element L 1 . This outer end 13 of the air guide element L 1 assumes the function of a baffle. The outer termination is connected via a web 14 with the tube 6 enclosing jacket 11 of the sleeve. The outer end 13 is curved according to its distance from the lateral surface of the tube 6 and according to its concentric arrangement with the tube 6. The front end 15 is designed as well as the connection of the web 14 to the end 13 rounded, in particular to avoid damage to the hair to be formed. The flow channel 12 formed by the air guide element L 1 is open in the tangential direction and thus to the row of bristles B 1 .

Durch die geschwungene Formgebung des Luftführungselementes L1 bildet sich auf der Rückseite des Strömungskanals 12 ein weiterer, in dem dargestellten Ausführungsbeispiel kleinerer Strömungskanal 16 aus, dessen äußerer Abschluss durch den Steg 14 gebildet ist. Dieser Strömungskanal 16 ist zu der anderen Borstenreihe B3 hin geöffnet.Due to the curved shape of the air guide element L 1 , a further, in the illustrated embodiment, smaller flow channel 16 forms on the back of the flow channel 12, whose outer end is formed by the web 14. This flow channel 16 is open to the other row of bristles B 3 out.

Die Hülse 11 und die Luftführungselemente L1 - L3 sind aus Aluminium, beispielsweise im Wege eines Strangpressverfahrens hergestellt.The sleeve 11 and the air guide elements L 1 - L 3 are made of aluminum, for example by means of an extrusion process.

Bei einem Betrieb der Haarbürste 1 strömt ein Warmluftstrom 17 über das Kupplungsstück 2, den Luftstromteiler 3 in den Luftkanal 7 ein. Beim Passieren des Luftstromteilers 3 wird - wie aus Figur 1 durch die Strömungspfeile schematisiert dargestellt - von dem Warmluftstrom 17 ein durch die Öffnungen 4 austretender Mantelluftstrom 18 ausgekoppelt, der durch die Konfigurierung der Öffnungen 4 des Luftstromteilers 3 im wesentlichen konzentrisch zur Mantelfläche des Rohrs 6 bzw. des Mantels der Hülse 11 ausströmt. Ist die Haarbürste 1 ist mit ihrem Bürstenabschnitt 5 in einen Haarstrang eingewickelt worden, so umgibt dieser konzentrisch das Rohr 6 und liegt an den Außenseiten der äußeren Abschlüsse der Luftführungselemente L1 - L3 an. Durch die Luftführungselemente L1 - L3 wird der Haarstrang auf Abstand zur Grundfläche der Hülse 11 gehalten. Somit kann aus den Luftaustrittsöffnungen 9 aus dem nach Art eines Sammlers fungierenden Luftkanal 7 Warmluft dem zu formenden Haarstrang zugeführt werden. Gleichzeitig ist der zu formende Haarstrang dem Mantelluftstrom ausgesetzt, der in den Strömungskanälen 16 der einzelnen Luftführungselemente L1 - L3 parallel zur Längserstreckung der Borstenreihen B1 - B3 transportiert wird. Die in diesem Mantelluftstrom 18 transportierte Wärme ist ausreichend, um den zu formenden Haarstrang über seine gesamte Breite hinweg einheitlich zu erwärmen. Das Zusammentreffen der aus den Luftaustrittsöffnungen 9 und in den Strömungskanälen 12, 16 transportierten Warmluftströmen resultiert in Turbulenzen, so dass ein Wärmeübergang von dem Luftstrom auf das Haar erleichtert ist. Die Ausbildung der Hülse 11 und insbesondere der Luftführungselemente L1 - L3 aus Aluminium unterstützt den Erwärmungsvorgang des Haares nicht unwesentlich, da bei einem Betrieb der Haarbürste 1 diese Aluminiumbestandteile durch den durch die Strömungskanäle 12, 16 jeweils transportierten Warmluftstrom erwärmt werden und diese Wärme aufgrund ihres großflächigen Anliegens an dem zu formenden Haarstrang auf diesen übertragen wird.During operation of the hairbrush 1, a hot air flow 17 flows via the coupling piece 2, the air flow divider 3 into the air duct 7. When passing through the air flow divider 3 is - as shown schematically by the flow arrows from the hot air flow 17 a through the openings 4 exiting jacket air flow 18 coupled by the configuration of the openings 4 of the air flow divider 3 substantially concentric with the lateral surface of the pipe 6 and ., The shell of the sleeve 11 flows out. If the hairbrush 1 has been wrapped with its brush portion 5 in a hair strand, so this concentrically surrounds the tube 6 and is located on the outer sides of the outer terminations of the air guide elements L 1 - L 3 at. By the air guide elements L 1 - L 3 , the hair strand is kept at a distance from the base surface of the sleeve 11. Thus, hot air can be supplied to the hair strand to be formed from the air outlet openings 9 from acting in the manner of a collector air duct 7 warm air. At the same time, the hair strand to be formed is exposed to the jacket air flow which is transported in the flow channels 16 of the individual air guide elements L 1 -L 3 parallel to the longitudinal extent of the bristle rows B 1 -B 3 . The heat carried in this shell air stream 18 is sufficient to uniformly heat the hair strand to be formed across its entire width. The coincidence of the hot air flows transported from the air outlet openings 9 and in the flow channels 12, 16 results in turbulence, so that heat transfer from the air stream to the hair is facilitated. The formation of the sleeve 11 and in particular the air guide elements L 1 - L 3 made of aluminum supports the heating process of the hair not insignificant, since during operation of the hair brush 1, these aluminum components are heated by the through the flow channels 12, 16 each transported warm air stream and this heat due their large-scale concern is transmitted to the hair strand to be formed on this.

Aus der Beschreibung der Erfindung wird deutlich, dass die Handhabung der beschriebenen Styling- und Curlinghaarbürste gegenüber Vorbekannten nicht nur verbessert ist sondern auch dass ein besseres Haarformergebnis erzielt werden kann. In dem Ausführungsbeispiel ist eine solche Styling- und Curlinghaarbürste beschrieben worden, bei der die Borstenreihen feststehend angeordnet sind. Gleichwohl lässt sich die Erfindung auch bei einer solchen Styling- und Curlinghaarbürste verwirklichen, bei der die Borstenreihen einziehbar angeordnet sind, so dass diese zum Lösen der Haarbürste von dem geformten Haarstrang oder -teil in das Rohr eingezogen werden können. From the description of the invention it is clear that the handling the described styling and Curlinghaarbürste compared with previously known not only is improved but also that a better hair shape result can be achieved. In the embodiment is a Such styling and Curlinghaarbürste been described, in which the Bristle rows are arranged fixed. Nevertheless, the invention can be even with such a styling and Curlinghaarbürste realize in which the rows of bristles are arranged retractable, so that these for releasing the hairbrush from the formed hair strand or part in the pipe can be retracted.
