- Hair straighteners have long been known and usually have two arms abutting each other, each of which has a Glättschenkel and a gripping leg. At least one of these Glättschenkel is assigned a hotplate. With the help of the gripping arms, the Glättschenkel can be pressed against each other, whereby a force is exerted on the located between the Glättschenkel hair. This is in particular the purpose of deforming the hair or to smooth by pulling simultaneously on the arms. In this case, the dosage of the force exerted by the Glättschenkel on the hair is crucial for the Frisierieri and can sometimes lead to mechanical damage or burning of the hair, if the hot plate too long acts on the hair to be smoothed.
- the EP 2 198 734 A1 discloses a hair styling device which is articulated by an articulated connection at least one arm articulated relative to the other arm, and this arm has an opposite with respect to a hinge axis of its working surface and arranged at an angle to the working surface and located within the Haarformaufsatzes Stellhebeifortatz.

- Such adjustment is formed by a hinge. It can divide the gripping arms into two gripping leg parts. The joint is now designed such that it allows a rotation of the gripping leg parts against each other, in particular parallel to the force, from a predefined force.
- the force transmitted to the gripping arms force is transmitted to the Glättschenkel and thus to the hair until the predefined force is reached and / or exceeded.
- the force gripping leg parts Upon reaching and / or exceeding the force gripping leg parts begin to rotate relative to each other, whereby the associated arm undergoes a kink and limited by the gripping arms on the hair transferable force.
- the force is particularly dependent on a joint resistance of the joint.
- one of the gripping leg parts approaches by a further buckling of the corresponding arm the opposite gripping leg of the other arm until they finally touch.
- a transferable by the gripping arms on the Glättschenkel and thus on the hair force is thus limited to the predefined force.
- a mechanical or thermal damage to the hair is avoided or at least limited by an excessive force transmission to the hair.
- the second gripping limb also has a joint which also divides it into two gripping limb parts.

- the variation of the individual joint resistances can be made stepless or stepped. A stepless variation can be ensured for example in a slip clutch by a stepless adjustment of the adjusting screw.
- the change of the bias of a spring leads to the change of the maximum force.
- a plurality of spring and / or clutches may be integrated in a joint between which can be changed, which in particular a stepped variation of the joint resistance and thus a stepped predefined force is possible.
- the joint resistance and thus the force can from the outside be predetermined and depend in particular on the nature of the hair.
- the setting of the joint resistance can optionally be done without any influence of the user and, for example, depend on a distance of the gripping surfaces.
- the heating plates 3 usually have the same shape and size and cover the Glättschenkel 4,4 'of the respective arm 2,2' partially.
- the heating plates 3 are mounted opposite each other on a respective Glättschenkel 4,4 '.
- both arms have 2,2 'the same size. They have an S-shaped course.
- the arms 2, 2 ' are each mounted on one another in their arcuate center, whereby they are at the same time each subdivided into a smoothing limb 4, 4' and a gripping limb 5, 5 '.
- a joint 6 which divides this gripping leg 5' into two gripping leg parts 7 and 7 '.
- the joint 6 is part of an adjusting device 17, by means of which by the gripping arms 5,5 'on the associated Glättschenkel 4,4' transferable force adjustable and / or can be limited. From a predefinable force causes the joint 6 kinking of the arm 2 '.

- one of the discs 10 has a connection to a gripping leg part 7 'and the other disc 10 has a connection to the other gripping leg part 7.
- the two smoothing legs 4, 4 'of the arms 2, 2' approach because the two gripping leg parts 7, 7 'come to a frictional connection , in particular a frictional connection, the two discs 10, which is generated by the tension of the adjusting screw 11, do not rotate relative to each other. Only when a predefined force, which corresponds in particular to the frictional engagement, is reached and / or exceeded, the two disks 10 and thus the gripping leg part 7, 7 'rotate relative to one another and lead to the bend of the associated gripping leg 5' until the rear gripper leg part 7 of the gripping leg 5 ', as in Fig.

- a spring 16 is provided which biases the lever 15 with its roller 14 against the rounding 12, wherein, starting from a predefined force, the roller 14 unrolls at the rounding 12 and thereby prevents further closing of the hair straightener 1.
- the gripping arms 5,5 'each have a stop 13, which have the same shape and size and are opposite each other. If the gripping arms 5, 5 'are then pressed against one another with a force, the posture of the lever 15 is maintained due to the pretensioning of the spring 16, and the smoothing leg 4' of the arm 2 'moves towards the opposite smoothing leg 4 of the arm 2 until finally touch the associated heating plates 3 or until the heating plates 3 touch the hair 9. Thus, the force exerted on the gripping arms 5,5 'force is transmitted to the hair 9 until this force reaches or exceeds the predefined force. The force is determined in particular by the bias of a spring 16. If the force is reached and / or exceeded, this leads, as in Fig.

Description
Die vorliegende Erfindung betrifft einen Haarglätter gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a hair straightener according to the preamble of
Haarglätter sind seit langem bekannt und weisen üblicherweise zwei aneinander gelagerte Arme auf, von denen jeder einen Glättschenkel und einen Greifschenkel besitzt. Zumindest einem dieser Glättschenkel ist dabei eine Heizplatte zugeordnet. Mit Hilfe der Greifschenkel können die Glättschenkel gegeneinander gedrückt werden, wodurch eine Kraft auf die sich zwischen den Glättschenkel befindlichen Haare ausgeübt wird. Dies dient insbesondere dem Zweck, die Haare zu verformen oder durch gleichzeitiges Ziehen an den Armen zu glätten. Dabei ist die Dosierung der Kraft, die durch die Glättschenkel auf die Haare ausgeübt wird entscheidend für das Frisierergebnis und kann bisweilen zu einer mechanischen Schädigung bzw. einem Verbrennen der Haare führen, sofern die zu heiße Heizplatte zu lange auf die zu glättenden Haare einwirkt.Hair straighteners have long been known and usually have two arms abutting each other, each of which has a Glättschenkel and a gripping leg. At least one of these Glättschenkel is assigned a hotplate. With the help of the gripping arms, the Glättschenkel can be pressed against each other, whereby a force is exerted on the located between the Glättschenkel hair. This is in particular the purpose of deforming the hair or to smooth by pulling simultaneously on the arms. In this case, the dosage of the force exerted by the Glättschenkel on the hair is crucial for the Frisierergebnis and can sometimes lead to mechanical damage or burning of the hair, if the hot plate too long acts on the hair to be smoothed.
Aus der
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Haarglätter der gattungsgemäßen Art eine verbesserte oder zumindest alternative Ausführungsform anzugeben, die sich insbesondere durch eine vereinfachte Handhabung und eine für die Haare schonende Anwendung auszeichnet.The present invention addresses the problem of providing a hair straightener of the generic type with an improved or at least alternative embodiment which is characterized in particular by a simplified handling and a hair-friendly application.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, bei einem Haarglätter mit zumindest zwei aneinander gelagerten Armen, ein auf die zu glättenden Haare ausübbare Druckkraft zu begrenzen oder zumindest einzustellen und dadurch insbesondere die Gefahr des Verbrennens und der mechanischen Schädigung der Haare zumindest zu reduzieren. Die Arme sind jeweils in einen Glättschenkel und einen Greifschenkel unterteilt, wobei zumindest einer der Glättschenkel zumindest eine Heizplatte aufweist. Die beiden Arme sind darüber hinaus derart aneinander gelagert, dass durch Zusammendrücken der Greifschenkel eine die Glättschenkel zusammendrückende Kraft auf diese und sich zwischen den Glättschenkeln befindliche Haare übertragen wird. Der Haarglätter kann dabei eine zangenähnliche Gestalt aufweisen. Zudem ist an einem der Greifschenkel eine Einstelleinrichtung vorgesehen, mittels welcher die von den Greifschenkeln auf die Glättschenkel übertragbare Kraft einstell- und/oder begrenzbar ist. Eine derartige Einstelleinrichtung ist durch ein Gelenk gebildet. Es kann die Greifschenkel in zwei Greifschenkelteile unterteilen. Das Gelenk ist nun derart gestaltet, dass es ein Verdrehen der Greifschenkelteile gegeneinander, insbesondere parallel zur Kraft, ab einer vordefinierten Kraft erlaubt. Damit wird die auf die Greifschenkel übertragene Kraft auf die Glättschenkel und somit auf die Haare übertragen, bis die vordefinierte Kraft erreicht und/oder überschritten ist. Beim Erreichen und/oder Überschreiten der Kraft beginnen die Greifschenkelteile sich relativ zueinander zu verdrehen, wodurch der zugehörige Arm einen Knick erfährt und die über die Greifschenkel auf die Haare übertragbare Kraft begrenzt. Die Kraft ist dabei insbesondere von einem Gelenkwiderstand des Gelenkes abhängig. Bei einer weiteren Erhöhung der Kraft, nähert sich eines der Greifschenkelteile durch ein weiteres Knicken des entsprechenden Armes dem gegenüberliegenden Greifschenkel des anderen Armes, bis diese sich schließlich berühren. Eine durch die Greifschenkel auf die Glättschenkel und somit auf die Haare übertragbare Kraft ist somit weiter auf die vordefinierte Kraft begrenzt. Dadurch wird insbesondere eine mechanische bzw. thermische Schädigung der Haare durch eine zu große Kraftübertragung auf die Haare vermieden oder zumindest begrenzt.The present invention is based on the general idea, in a hair straightener with at least two arms mounted on one another, to limit or at least adjust a compressive force which can be exerted on the hair to be smoothed and thereby at least reduce the risk of burning and mechanical damage to the hair. The arms are each divided into a Glättschenkel and a gripping leg, wherein at least one of the Glättschenkel has at least one heating plate. The two arms are also stored in such a way that by compressing the gripping arms a Glättschenkel compressive force is transmitted to this and located between the Glättschenkeln hair. The hair straightener can have a pliers-like shape. In addition, an adjusting device is provided on one of the gripping arms, by means of which the transferable from the gripping arms on the Glättschenkel force is adjustable and / or limited. Such adjustment is formed by a hinge. It can divide the gripping arms into two gripping leg parts. The joint is now designed such that it allows a rotation of the gripping leg parts against each other, in particular parallel to the force, from a predefined force. Thus, the force transmitted to the gripping arms force is transmitted to the Glättschenkel and thus to the hair until the predefined force is reached and / or exceeded. Upon reaching and / or exceeding the force gripping leg parts begin to rotate relative to each other, whereby the associated arm undergoes a kink and limited by the gripping arms on the hair transferable force. The force is particularly dependent on a joint resistance of the joint. In a further increase in the force, one of the gripping leg parts approaches by a further buckling of the corresponding arm the opposite gripping leg of the other arm until they finally touch. A transferable by the gripping arms on the Glättschenkel and thus on the hair force is thus limited to the predefined force. As a result, in particular a mechanical or thermal damage to the hair is avoided or at least limited by an excessive force transmission to the hair.
Bei einer weiteren Ausführungsform der erfindungsgemäßen Lösung, weist auch der zweite Greifschenkel ein Gelenk auf, das diesen ebenfalls in zwei Greifschenkelteile unterteilt. Das Gelenk des zweiten Greifschenkels weist nun auch einen Gelenkwiderstand auf, der nicht zwingend gleich dem Gelenkwiderstand des ersten Greifschenkels ist. Bei Gelenken, die den gleichen Gelenkwiderstand aufweisen, wird die Begrenzung der Kraft entsprechend der oberen Beschreibung erreicht, wobei hier beide Arme im Greifbereich einen Knick erfahren bis sich die entsprechend gegenüberliegenden Greifschenkelteile berühren. Sind jedoch die Gelenkwiderstände der jeweiligen Arme unterschiedlich, so wird die maximale Kraft durch den kleineren Gelenkwiderstand bestimmt.In a further embodiment of the solution according to the invention, the second gripping limb also has a joint which also divides it into two gripping limb parts. The joint of the second gripping leg now also has a joint resistance, which is not necessarily equal to the joint resistance of the first Gripping leg is. For joints that have the same joint resistance, the limitation of the force is achieved according to the description above, here both arms in the gripping area experience a kink until the corresponding opposite gripping leg parts touch. However, if the joint resistance of the respective arms are different, then the maximum force is determined by the smaller joint resistance.
Es versteht sich, dass das Gelenk auch zum Lagern der beiden Arme verwendet werden kann und diese entsprechend in Greifschenkel und Glättschenkel unterteilt. Ein Arm kann weiter mehrere Gelenke aufweisen, die sich nicht zwingend im Bereich der Greifschenkel oder Glättschenkel befinden, sondern eine Kombination aus beiden Möglichkeiten aufweisen.It is understood that the joint can also be used to support the two arms and this subdivided accordingly into gripper legs and Glättschenkel. An arm may further comprise a plurality of joints which are not necessarily located in the region of the gripping limbs or Glättschenkel, but have a combination of both possibilities.
Der Gelenkwiderstand des zumindest einen Gelenks kann insbesondere durch eine Federeinrichtung verändert bzw. eingestellt werden. Hierzu ist insbesondere eine Vorspannung einer entsprechenden Feder maßgeblich. Als Feldern, kommen insbesondere in Betracht: Eine Spiralfeder, Schenkelfeder, Ringfeder, Biegefeder oder Spannfeder. Auch ist der Gelenkwiderstand eines Gelenkes durch eine Kupplung, insbesondere eine Rutschkupplung einstellbar. Ist der Gelenkwiderstand des Gelenkes durch eine Federeinrichtung realisiert, ist zudem sichergestellt, dass die jeweiligen Greifschenkelteile beim Loslassen des Haarglätters in ihre Ausgangsstellung zurückkehren.The joint resistance of the at least one joint can be changed or adjusted in particular by a spring device. For this purpose, in particular a bias of a corresponding spring is relevant. As fields, are particularly considered: A coil spring, leg spring, ring spring, spiral spring or tension spring. Also, the joint resistance of a joint by a clutch, in particular a slip clutch is adjustable. If the joint resistance of the joint realized by a spring means, it is also ensured that the respective gripping leg parts return to their starting position when releasing the hair straightener.
Ferner sind Gelenke vorstellbar, die eine beliebig Variation der entsprechenden Gelenkwiderstände erlauben. Im Falle der Rutschkupplung sei hier insbesondere auf eine Einstellschraube hingewiesen, die einen Kraftschluss, insbesondere einen Reibschluss, der Kupplung beeinflusst. Die Variation der einzelnen Gelenkwiderstände kann dabei stufenlos oder gestuft erfolgen. Eine stufenlose Variation kann beispielsweise bei einer Rutschkupplung durch eine stufenlose Einstellung der Einstellschraube gewährleistet sein. Weiter führt beispielsweise die Änderung der Vorspannung einer Feder zur Änderung der Maximalkraft. Auch können mehrere Feder und/oder Kupplungen in einem Gelenk integriert sein, zwischen denen gewechselt werden kann, womit insbesondere eine gestufte Variation des Gelenkwiderstandes und somit eine gestufte vordefinierte Kraft ermöglich wird. Der Gelenkwiderstand und somit die Kraft können dabei von außen vorgegeben werden und insbesondere von der Beschaffenheit der Haare abhängen. Die Einstellung des Gelenkwiderstandes kann optional auch ohne eine Einflussnahme des Nutzers erfolgen und beispielsweise von einem Abstand der Greifflächen abhängen.Furthermore, joints are conceivable that allow any variation of the corresponding joint resistance. In the case of the slip clutch, reference should be made in particular to an adjustment screw which influences a frictional connection, in particular a frictional connection, of the clutch. The variation of the individual joint resistances can be made stepless or stepped. A stepless variation can be ensured for example in a slip clutch by a stepless adjustment of the adjusting screw. Further, for example, the change of the bias of a spring leads to the change of the maximum force. Also, a plurality of spring and / or clutches may be integrated in a joint between which can be changed, which in particular a stepped variation of the joint resistance and thus a stepped predefined force is possible. The joint resistance and thus the force can from the outside be predetermined and depend in particular on the nature of the hair. The setting of the joint resistance can optionally be done without any influence of the user and, for example, depend on a distance of the gripping surfaces.
Es sei darauf hingewiesen, dass die hier erwähnten Ausführungsformen und Ihre Variationen nicht auf einen Haarglätter beschränkt, sondern auch auf ein beliebiges zangenähnliches Werkzeug übertragbar sind und bei diesem zum gleichen Ergebnis führen.It should be noted that the embodiments mentioned here and their variations are not limited to a hair straightener, but are also applicable to any plier-like tool and lead to the same result in this.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.
