Abstract
Description
Die Erfindung betrifft einen Schneidsatz für eine elektrische Haarschneidemaschine gemäß Patentanspruch 1 sowie eine elektrische Haarschneidemaschine gemäß Patentanspruch 7.The invention relates to a cutting set for an electric hair clipper according to
Allgemein bekannt ist die Verwendung von Schneidsätzen für Haarschneidemaschinen. Bekannte Schneidsätze für elektrische Haarschneidemaschinen, wie sie etwa die
Kritisch für die Effektivität solcher Schneidsätze ist es, dass Scherkamm und Schermesser mit einer definierten Andruckkraft, dem sogenannten Schneiddruck, eng aneinander geführt werden. Herrscht ein zu geringer Schneiddruck, d. h. eine zu geringe Andruckkraft, verschlechtert sich das Schneidverhalten, im Extremfall kann das zu schneidende Haar in den sich ausbildenden Zwischenraum beim Abheben des Schermessers vom Scherkamm hineingezogen werden, was den Abschneideprozess behindert und zu einem schmerzhaften Festklemmen einzelner Haare führen kann.Critical to the effectiveness of such cutting sets is that Scherkamm and shearing blades with a defined pressure, the so-called cutting pressure, are guided close to each other. If the cutting pressure is too low, d. H. Too little pressure force, the cutting behavior deteriorates, in extreme cases, the hair to be cut can be drawn into the forming gap when lifting the doctor from the cutting comb, which hinders the cutting process and can lead to a painful clamping individual hair.
Daher ist es üblich, eine Andruckvorrichtung vorzusehen, die sicherstellt, dass Scherkamm und Schermesser gegeneinander mit der erforderlichen Andruckkraft geführt werden. Andruckvorrichtungen in Form von Federarmen sind beispielsweise aus der
Allerdings wird ein optimales Schnittergebnis genau dann erreicht, wenn Scherkamm und Schermesser exakt parallel zur vorgesehenen Schnittkante geführt werden.However, an optimal cutting result is achieved exactly when the cutting comb and the shearing blades are guided exactly parallel to the intended cutting edge.
Einer solchen ideal linearen Bewegung stehen die bekannten, vorstehend beschriebenen Andruckvorrichtungen jedoch insofern entgegen, als sie in der Regel Zwangsbedingungen für die relative Bewegung von Scherkamm und Schermesser zueinander darstellen, da sie mindestens eine mechanische Verbindung zwischen einem festen und einem bewegten Bauteil darstellen, die nicht in alle Richtungen frei beweglich ist. So werden die das Schermesser führenden Federarme beim Durchlaufen der Oszillationsbewegung seitlich ausgelenkt, so dass das Schermesser keine ideale lineare Querbewegung relativ zum Scherkamm erfährt. Die sich ergebende kreisbogensegmentförmige Bewegung ist für ein optimales Schneidergebnis nachteilig.However, such an ideally linear movement is precluded by the prior art pressure devices described above in that they are generally constraints on the relative movement of the shear comb and shear blades relative to one another since they provide at least one mechanical connection between a fixed and a moving component is freely movable in all directions. Thus, the shear blades leading spring arms are deflected laterally when passing through the oscillatory motion, so that the shearing blade experiences no ideal linear transverse movement relative to the shearing comb. The resulting circular arc segment-shaped movement is disadvantageous for an optimal cutting result.
Die vorangemeldete, jedoch nachveröffentlichte
Ziel der Erfindung ist daher die Bereitstellung eines Schneidsatzes für eine elektrische Haarschneidemaschine bzw. eine Haarschneidemaschine, der bzw. die eine optimale Führung der Bewegung von Schermesser und Scherkamm bei gleichzeitiger Bereitstellung des notwendigen Schneiddruckes gewährleistet.The aim of the invention is therefore to provide a cutting set for an electric hair clipper or a hair clipper, which ensures optimal management of the movement of the shear blade and shearing comb while providing the necessary cutting pressure.
Dieses Ziel wird erfindungsgemäß erreicht durch einen Schneidsatz für eine elektrische Haarschneidemaschine mit den Merkmalen des Patentanspruchs 1 sowie durch eine Haarschneidemaschine mit den Merkmalen des Patentanspruchs 7.This object is achieved by a cutting set for an electric hair clipper with the features of
Der Erfindung liegt die Erkenntnis zu Grunde, dass eine elegante und effiziente Möglichkeit zur Bereitstellung des Andrucks zwischen Scherkamm und Schermesser darin besteht, mindestens einen Magneten so zwischen diesen beiden Bauteilen anzuordnen, dass der notwendige Schneiddruck bereitgestellt wird, während gleichzeitig ein zwischen Schermesser und Scherkamm angeordnetes Führungsblech eine ideal lineare Relativbewegung von Scherkamm und Schermesser ermöglicht.The invention is based on the finding that an elegant and efficient way to provide the contact pressure between the cutting comb and the doctor blade is to arrange at least one magnet between these two components so that the necessary cutting pressure is provided, while at the same time an interposed between the shear blade and shearing comb Guide plate allows an ideal linear relative movement of shearing comb and shearing blades.
Der erfindungsgemäße Schneidsatz für elektrische Haarschneidemaschinen weist somit einen Scherkamm und ein auf dem Scherkamm aufliegendes Schermesser, welche über einen antriebsseitig befestigten Mitnehmer relativ zueinander oszillierend bewegbar sind, auf, wobei zusätzlich mindestens ein Magnet im Bereich des Schermessers und/oder des Scherkamms angeordnet ist. Dabei ist der Magnet nicht das einzige zwischen diesen beiden Bauteilen angeordnete Element; vielmehr ist dort das Führungsblech zur Führung des Schermessers zwischen besagten Bauteilen vorgesehen.The cutting set according to the invention for electric hair clipping machines thus has a shearing comb and a shearing ridge resting on the shearing ridge, which are oscillatingly movable relative to each other via a driver mounted on the drive side, wherein additionally at least one magnet in the region of the shearing blade and / or the shearing comb is arranged. In this case, the magnet is not the only element arranged between these two components; rather, there is that Guide plate provided for guiding the shearing blade between said components.
Der mindestens eine Magnet kann an unterschiedlichen Stellen des Schneidsatzes angeordnet sein. Es ist beispielsweise möglich, einen Magneten in der Schermesser/Mitnehmereinheit zu montieren, so dass die Magnetkraft zwischen Magnet und Scherkamm den Schneiddruck erzeugt.The at least one magnet can be arranged at different locations of the cutting set. For example, it is possible to mount a magnet in the shearing blade / driver unit so that the magnetic force between the magnet and the shearing comb generates the cutting pressure.
Alternativ kann ein Magnet am Schneidkamm angeordnet sein, wofür in vorteilhafter Ausgestaltung eine Vertiefung im Schneidkamm ausgeformt ist, in welche der Magnet passt. In diesem Fall erzeugt die Magnetkraft zwischen Magnet und Schermesser den Schneiddruck.Alternatively, a magnet may be arranged on the cutting comb, for which, in an advantageous embodiment, a depression is formed in the cutting comb into which the magnet fits. In this case, the magnetic force between the magnet and the blade produces the cutting pressure.
Schließlich ist es auch noch denkbar, jeweils mindestens einen Magneten in der Schermesser/Mitnehmereinheit und im Scherkamm zu montieren. In diesem Fall wird der Schneiddruck durch die Magnetkraft zwischen den beiden Magneten bereitgestellt. Diese Anordnung ermöglicht es, besonders hohe Schneiddrücke zu erzielen. Allgemein ist der Schneiddruck durch Auswahl des Magneten beeinflussbar.Finally, it is also conceivable to mount in each case at least one magnet in the shearing blade / driver unit and in the shearing comb. In this case, the cutting pressure is provided by the magnetic force between the two magnets. This arrangement makes it possible to achieve very high cutting pressures. In general, the cutting pressure can be influenced by selecting the magnet.
In einer besonders bevorzugten Ausführungsform ist weiter ein Verstellelement mit einem Gewinde vorgesehen, mit dessen Hilfe der Abstand zwischen Magnet und Scherkamm, damit also die Magnetkraft zwischen diesen beiden Bauteilen und demnach der Schneiddruck variiert werden kann.In a particularly preferred embodiment, an adjusting element is further provided with a thread, by means of which the distance between the magnet and shearing comb, so that thus the magnetic force between these two components and therefore the cutting pressure can be varied.
Vorzugsweise ist das Führungsblech für das Schermesser verschiebbar ausgeführt, wodurch eine Schnittlängenverstellung ermöglicht wird.Preferably, the guide plate is designed to be displaceable for the shearing blade, whereby a cutting length adjustment is made possible.
