Description
Die vorliegende Erfindung betrifft einen Schneidsatz für eine Haarschneidemaschine nach dem Oberbegriff des Patentanspruchs 1, eine Haarschneidemaschine nach dem Oberbegriff des Patentanspruchs 11, sowie ein Haartransportelement nach dem Oberbegriff des Patentanspruchs 12.The present invention relates to a cutting set for a hair clipper according to the preamble of
Haarschneidemaschinen sind im Stand der Technik in einer Vielzahl von Ausführungen bekannt. So beschreibt beispielsweise die
Auch Haarschneidemaschinen mit mehreren Schneideinheiten sind im Stand der Technik bekannt. So offenbart beispielsweise die
In der
Eine Haarschneidemaschine mit einem auswechselbaren Schneidsatz, bestehend zumindest aus einem Scherkamm und einem im Wesentlichen parallel zur Vorderkante des Scherkamms über einen Mitnehmer in Querrichtung oszillierend antreibbaren Schermesser, sowie einer Schnittlängenverstelleinrichtung, bestehend aus einem Betätigungselement, das an einem Gehäuse der Haarschneidemaschine angelenkt ist und auf den Schneidsatz derart einwirkt, daß eine relative Verschiebung zwischen dem Scherkamm und dem Schermesser in Längsrichtung möglich ist, wird beispielsweise in der
Die bekannten Haarschneidemaschinen und Schneidsätze für Haarschneidemaschinen weisen jedoch einen gravierenden Nachteil auf:However, the known hair clippers and cutting sets for hair clippers have a serious disadvantage:
So kommt es beim Schneiden von Haaren mit den im Stand der Technik bekannten Schneidsätzen für Haarschneidemaschinen, je nach Schneidposition zu einer Anhäufung von Haarabschnitten auf der Haarschneidemaschine. Diese Anhäufung von Haarabschnitten versperrt zum einen die Sicht auf den Schneidbereich und verschlechtert zum anderen die Zufuhr noch nicht geschnittener Haare. Der Friseur muss daher nach jeder Anhäufung von Haaren die Maschine zur Seite kippen, bzw. die Haare vom Schneidsatz der Maschine abschütteln. Dies ist insbesondere dann lästig, wenn ein letzter Haarfeinschnitt erfolgen soll.Thus, when cutting hair with the known in the prior art cutting sets for hair clippers, depending on the cutting position to an accumulation of hair on the hair clipper. This accumulation of hair locks on the one hand the view of the cutting area and on the other deteriorates the supply of not yet cut hair. The hairdresser must therefore tilt the machine to the side after each accumulation of hair, or shake off the hair from the cutting set of the machine. This is particularly troublesome when a final hair incision is to take place.
Aufgabe der vorliegenden Erfindung ist es daher, einen Schneidsatz für eine Haarschneidemaschine bereitzustellen, der diesen Nachteil nicht aufweist, sowie eine Haarschneidemaschine mit einem solchen Schneidsatz bereitzustellen.Object of the present invention is therefore to provide a cutting set for a hair clipper, which does not have this disadvantage, and to provide a hair clipper with such a cutting set.
Diese Aufgabe wird gelöst durch einen Schneidsatz nach Patentanspruch 1, durch eine Haarschneidemaschine nach Patentanspruch 11, sowie durch ein Haartransportelement nach Patentanspruch 12. Vorteilhafte Ausführungsformen sind in den jeweiligen Unteransprüchen angegeben.This object is achieved by a cutting set according to
Der erfindungsgemäße Schneidsatz weist zumindest einen feststehenden oder einen verstellbaren Scherkamm und ein im Wesentlichen parallel zur Vorderkante des Scherkamms in Querrichtung oszillierend antreibbares Schermesser auf, sowie ein Haartransportelement, welches eine Transportzahnung mit Zähnen aufweist, die im Wesentlichen entlang der und beabstandet zur Schneidkante des Schermessers angeordnet sind. Das Haartransportelement kann dabei Teil des Schneidsatzes sein, beispielsweise wenn der gesamte Schneidsatz austauschbar ist. Das Schermesser ist zwischen dem Scherkamm und dem Haartransportelement angeordnet, wobei die Schneidkante des Schermessers die von den Spitzen der Zähne der Transportzahnung gebildete Vorderkante des Haartransportelements überragt. Bei einem verstellbaren Scherkamm bleibt der Abstand der Haartransporteinrichtung relativ zu einem Gehäuse der Haarschneidemaschine gleich.The cutting set according to the invention has at least one fixed or adjustable shearing comb and a shearing blade drivable in an oscillating manner substantially parallel to the front edge of the shearing comb, and a hair transporting element having a toothed toothing arrangement arranged substantially along and spaced from the cutting edge of the shearing blade are. The hair transport element can be part of the cutting set, for example if the entire cutting set is exchangeable. The shearing blade is arranged between the shearing comb and the hair transporting element, wherein the cutting edge of the shearing blade projects beyond the front edge of the hair transporting element formed by the tips of the teeth of the transporting toothing. With an adjustable cutting comb the distance of the hair transporting device remains the same relative to a housing of the hair clipper.
Vorzugsweise ist der erfindungsgemäße Schneidsatz als ein austauschbarer Kopf einer Haarschneidemaschine ausgebildet, bei welchem vorteilhafterweise Schermesser, Scherkamm und Haartransportelement bereits miteinander verbunden sind, so daß er gegen einen gewöhnlichen im Stand der Technik bekannten Schneidsatz, der kein Haartransportelement aufweist, schnell ausgetauscht werden kann.Preferably, the cutting set according to the invention is designed as a replaceable head of a hair cutting machine, in which advantageously shear blade, shearing comb and Haartransportelement are already interconnected, so that it can be quickly replaced with a conventional known in the art cutting set, which has no hair transport element.
Die Transportzahnung weist vorteilhafterweise ein im Wesentlichen sägezahnförmiges Querschnittsprofil auf. Unter einem "im Wesentlichen sägezahnförmigen Profil" soll hier ein Querschnittsprofil verstanden werden, bei dem die Zähne jeweils eine Steilflanke und eine flache Flanke aufweisen. Die Steilflanke ist dabei dadurch bestimmt, daß ihr Anstiegswinkel relativ zur Grundlinie der Transportzahnung, also zu der Linie, auf und entlang der die Zähne der Transportzahnung angeordnet sind, steiler ist, als der Anstiegswinkel zwischen der flachen Flanke und der Grundlinie. Die Spitzen der Zähne können dabei auch abgeflacht und / oder abgerundet sein. Die Steilflanken der Zähne weisen vorzugsweise Winkel von im Wesentlichen 90° relativ zur Grundlinie auf, wobei der Begriff "im Wesentlichen 90°" in diesem Zusammenhang Winkel zwischen 80° und 100° einschließen soll.The transport toothing advantageously has a substantially sawtooth-shaped cross-sectional profile. A "substantially sawtooth-shaped profile" is to be understood here as a cross-sectional profile in which the teeth respectively have a steep flank and a flat flank. The steep flank is determined by the fact that their angle of rise relative to the base line of the transport toothing, ie to the line on and along which the teeth of the transport toothing are arranged, is steeper than the angle of rise between the flat flank and the baseline. The tips of the teeth can also be flattened and / or rounded. The steep flanks of the teeth preferably have angles of substantially 90 ° relative to the baseline, wherein the term "substantially 90 °" in this context is intended to include angles between 80 ° and 100 °.
Das Haartransportelement ist entweder fest mit dem Schermesser verbunden, wobei es vorzugsweise flächig mit dem Schermesser verbunden ist, oder es wirkt mit der Bewegung des Schermessers relativ zum Scherkamm über ein Verbindungselement zusammen. Das Haartransportelement kann dann beispielsweise über einen Mitnehmer mit dem Schermesser oszillierend antreibbar verbunden sein. Dadurch, daß sich das Schermesser mit dem Haartransportelement beim Schneiden der Haare schnell auf dem Scherkamm hin und her bewegt, werden die Haare abgeschnitten und an den sich ebenfalls hin- und her bewegenden Steilflanken der Sägezähne des Haartransportelements in Richtung der Hin- und Her-Bewegung des Schermessers, also in Querrichtung zur Schnittrichtung, beschleunigt, von der Haarschneidemaschine wegbewegt und entfernt. Die Schnittrichtung ist eine Richtung senkrecht zur Schneidkante des Schermessers.The hair transport element is either firmly connected to the shearing blade, wherein it is preferably connected flat with the shearing blade, or it cooperates with the movement of the shaver relative to the shearing comb via a connecting element. The hair transport element can then be connected in an oscillating manner, for example, via a driver with the shearing blade. The fact that the shaving blade with the hair transport element when cutting the hair quickly moves back and forth on the cutting comb, the hair is cut off and on the also reciprocating steep slopes of the saw teeth of the hair transport element in the direction of the reciprocating motion the shear blade, so in the transverse direction to the cutting direction, accelerated, moved away from the hair clipper and removed. The cutting direction is a direction perpendicular to the cutting edge of the doctor blade.
Da entlang der gesamten Schneidkante Haare abgeschnitten werden, erstreckt sich die Transportzahnung in vorteilhaften Ausbildungen im Wesentlichen entlang der gesamten Schneidkante des Schermessers, so daß die Zähne der Transportzahnung im Wesentlichen entlang der gesamten Schneidkante des Schermessers verlaufend an dem Haartransportelement angeordnet sind, um möglichst alle abgeschnittenen Haare zu erfassen und von der Haarschneidemaschine zu entfernen.Since hair is cut along the entire cutting edge, the transport toothing extends in advantageous embodiments substantially along the entire cutting edge of the doctor, so that the teeth of the transport toothing substantially along the entire cutting edge of the doctor blade are arranged on the hair transport element to capture as possible all cut hair and remove it from the hair clipper.
Damit die abgeschnittenen Haare nicht nur in eine der beiden Querrichtungen der Hin- und Her-Bewegung des Schermessers relativ zum Scherkamm beschleunigt werden, sondern ein Teil der Haarabschnitte in die eine Querrichtung und der andere Teil der Haarabschnitte in die andere Querrichtung beschleunigt wird, so daß die Haarabschnitte sowohl nach links, als auch nach rechts von der Haarschneidemaschine abgeworfen werden, weist die Transportzahnung einen ersten und einen zweiten Teilabschnitt auf, wobei die Steilflanken der Sägezähne des ersten Teilabschnitts der Transportzahnung und die Steilflanken der Sägezähne des zweiten Teilabschnitts der Transportzahnung in im Wesentlichen einander entgegengesetzte Richtungen weisen. Der Winkel zwischen den beiden im Wesentlichen einander entgegengesetzten Richtungen beträgt vorzugsweise zwischen 160° und 200°.Thus, the cut hairs are not only accelerated in one of the two transverse directions of the reciprocating motion of the doctor blade relative to the shearing comb, but a portion of the hair sections in the one transverse direction and the other part of the hair sections is accelerated in the other transverse direction, so that the hair sections are dropped both to the left and to the right of the hair clipper, the transport teeth on a first and a second portion, wherein the steep edges of the saw teeth of the first portion of the transport teeth and the steep edges of the saw teeth of the second portion of the transport teeth in substantially pointing in opposite directions. The angle between the two substantially mutually opposite directions is preferably between 160 ° and 200 °.
In einer besonders bevorzugten Ausführungsform sind die Sägezähne im ersten Teilabschnitt der Transportzahnung spiegelsymmetrisch zu den Sägezähnen im zweiten Teilabschnitt der Transportzahnung ausgebildet, wobei die Spiegelachse senkrecht zur Grundlinie der Transportzahnung und mittig durch die Transportzahnung verläuft, so daß der erste Teilabschnitt und der zweite Teilabschnitt zur Bildung der Transportzahnung spiegelsymmetrisch so aneinander grenzen, daß die Steilflanken der Zähne der Transportzahnung in einander entgegengesetzte Richtungen weisen. Dadurch können abgeschnittene Haare zu beiden Seiten der Haarschneidemaschine abgeworfen werden.In a particularly preferred embodiment, the saw teeth are formed mirror-symmetrically to the saw teeth in the second section of the transport teeth in the first section of the transport teeth, wherein the mirror axis is perpendicular to the base line of the transport teeth and centrally through the transport teeth, so that the first section and the second section for forming the transport teeth mirrors mirror symmetry to each other so that the steep flanks of the teeth of the transport teeth facing each other in opposite directions. As a result, cut hairs can be dropped on both sides of the hair clipper.
Die Transportzahnung weist in einer vorteilhaften Ausbildung mittig einen Mittelzahn auf, der beispielsweise dreieckartig oder dreieckig ausgebildet sein kann, wobei er bevorzugt zwei Steilflanken aufweist. Der Mittelzahn kann aber beispielsweise auch rechteckig oder trapezförmig ausgebildet sein. Im Falle einer spiegelsymmetrischen Anordnung der Zähne der Transportzahnung erstreckt sich die Spiegelachse durch die Mitte des Mittelzahns hindurch, so daß beide Teilabschnitte der Transportzahnung jeweils einen halben Mittelzahn aufweisen.In an advantageous embodiment, the transport toothing has in the center a central tooth, which can be triangular or triangular, for example, and preferably has two steep flanks. However, the central tooth may for example also be rectangular or trapezoidal. In the case of a mirror-symmetrical arrangement of the teeth of the transport teeth, the mirror axis extends through the center of the central tooth through, so that both sections of the transport toothing each have a half center tooth.
Die Zähne der Transportzahnung weisen im Wesentlichen dreieckförmige oder dreieckige Querschnittsprofile auf.The teeth of the transport teeth have substantially triangular or triangular cross-sectional profiles.
Die Hüllkurve der Transportzahnung weist im Wesentlichen vier miteinander verbundene Abschnitte auf, die die Transportzahnung umschließen bzw. umhüllen. Der erste Abschnitt der Hüllkurve wird gebildet durch die Vorderkante des Haartransportelements, welche durch die Gesamtzahl der kürzesten Verbindungen zwischen einander benachbarter Spitzen einzelner Zähne der Transportzahnung definiert ist. Der zweite Abschnitt wird gebildet durch die Grundlinie der Transportzahnung, also durch die Linie, auf der die den Spitzen der Zähne gegenüber liegenden Basisflächen der Zähne angeordnet sind. Der dritte und vierte Abschnitt der Hüllkurve wird von den beiden seitlichen Begrenzungen der Transportzahnung gebildet.The envelope of the transport toothing has essentially four interconnected sections which enclose or envelop the transport toothing. The first portion of the envelope is formed by the leading edge of the hair transport element, which is defined by the total number of shortest connections between adjacent tips of individual teeth of the transport toothing. The second section is formed by the base line of the transport toothing, that is to say by the line on which the base surfaces of the teeth lying opposite the tips of the teeth are arranged. The third and fourth sections of the envelope are formed by the two lateral boundaries of the transport toothing.
Die Spitzen der Zähne der Transportzahnung spannen somit den ersten Teil der Hüllkurve auf. Vorteilhafterweise begrenzt der erste Teil der Hüllkurve die Transportzahnung konvex, wobei auch eine geradlinige Begrenzung in dieser Offenbarung als eine konvexe Begrenzung bezeichnet werden soll. Bevorzugt ist die Transportzahnung dabei so ausgebildet, daß die Hüllkurve der Transportzahnung die gesamte Transportzahnung konvex umschließt.The tips of the teeth of the transport toothing thus span the first part of the envelope. Advantageously, the first part of the envelope convexly limits the transport toothing, wherein a rectilinear boundary in this disclosure should also be referred to as a convex boundary. Preferably, the transport toothing is designed so that the envelope the transport toothing surrounds the entire transport toothing convex.
In einer besonders bevorzugten Ausführungsform verläuft die Vorderkante des Haartransportelements parallel zur Schneidkante des Schermessers. Der Abstand zwischen der Vorderkante des Haartransportelements, also der Vorderkante der Transportzahnung und der Schneidkante des Schermessers beträgt bevorzugt zwischen 1 mm und 5 mm. So kann in optimaler Weise dafür gesorgt werden, daß die abgeschnittenen Haare von dem Haartransportelement von der Mitte der Haarschneidemaschine seitlich wegbewegt werden.In a particularly preferred embodiment, the leading edge of the hair transport element runs parallel to the cutting edge of the shearing blade. The distance between the front edge of the hair transport element, ie the leading edge of the transport toothing and the cutting edge of the doctor blade is preferably between 1 mm and 5 mm. Thus, it can be optimally ensured that the cut hairs are moved laterally away from the hair transporting member from the center of the hair cutting machine.
Der Abstand zwischen der Vorderkante des Scherkamms und der Schneidkante des Schermessers ist vorzugsweise mit einem Betätigungselement einstellbar, das entweder an den Schneidsatz gekoppelt ist und somit Teil des Schneidsatzes sein kann oder an die Haarschneidemaschine. Bevorzugt bleibt die relative Position der Schneidkante des Schermessers zu der Vorderkante des Haartransportelements gleich, wenn der Abstand zwischen der Vorderkante des Scherkamms und der Schneidkante des Schermessers geändert wird, es sind jedoch auch Ausbildungen vorstellbar, bei denen dieser Abstand variiert werden kann, um, je nach Anforderung an die Länge der Haarabschnitte ein optimales Abwerfen der Haare von der Haarschneidmaschine zu ermöglichen.The distance between the leading edge of the cutting comb and the cutting edge of the doctor blade is preferably adjustable with an actuator which is either coupled to the cutting set and thus may be part of the cutting set or to the hair clipper. Preferably, the relative position of the cutting edge of the doctor blade to the leading edge of the hair transporting member remains the same when the distance between the leading edge of the cutting comb and the cutting edge of the doctor blade is changed, but it is also conceivable training in which this distance can be varied to, je to allow for optimal hair removal from the hair clipper after request to the length of the hairpieces.
Die erfindungsgemäße Haarschneidemaschine ist bevorzugt elektrisch angetrieben. Sie weist, neben dem erfindungsgemäßen Schneidsatz, vorteilhafterweise ein Gehäuse auf, das beispielsweise mit dem Scherkamm fest verbunden ist und einen Elektromotor zum oszillierenden Antreiben des Schermessers umschließt. Sie weist vorzugsweise weiterhin einen Mitnehmer auf, der mit dem Elektromotor und dem Schermesser so verbunden ist, daß er das Schermesser oszillierend, bevorzugt in Querrichtung zur Schnittrichtung, antreibt, wenn der Elektromotor eingeschaltet ist. Der Scherkamm kann optional an dem Gehäuse befestigt sein. Vorteilhafterweise ist jedoch das Haartransportelement entweder mit dem Schermesser fest verbunden oder mit dem Schermesser so verbunden, daß sich das Haartransportelement mit dem Schermesser mitbewegt, wenn das Schermesser oszillierend angetrieben wird, damit die Anhäufung der Haarabschnitte nicht die Sicht auf den Schneidebereich versperrt und die Zufuhr zu schneidender Haare nicht verschlechtert oder blockiert. Das Haartransportelement des Schneidsatzes der Haarschneidemaschine weist in einer möglichen Ausführungsform einen Eingriff zur Aufnahme des Mitnehmers auf.The hair clipper according to the invention is preferably driven electrically. It has, in addition to the cutting set according to the invention, advantageously a housing which is firmly connected, for example, with the shearing comb and encloses an electric motor for oscillating driving of the shearing blade. It preferably still has a driver on, which is connected to the electric motor and the shearing blade so that it oscillates the shearing blade, preferably in the transverse direction to the cutting direction, drives when the electric motor is turned on. The shearing comb may optionally be attached to the housing. Advantageously, however, the hair transport element is either firmly connected to the shearing blade or connected to the shearing blade so that the hair transporting element moves with the shearing blade, when the shearing blade is driven to oscillate, so that the accumulation of the hair sections does not obstruct the view of the cutting area and the supply to cutting hair does not deteriorate or block. The hair transport element of the cutting set of the hair clipper has, in one possible embodiment, an engagement for receiving the driver.

Das Haartransportelement 10 weist eine Grundlinie 16 auf, auf der die Transportzahnung 12 sitzt, bzw. auf der die einzelnen Zähne der Transportzahnung 12 angeordnet sind. Parallel zur Schneidkante 18 des Schermessers 8, die ebenfalls als gestrichelte Linie in
In
Wie insbesondere in
Ein schräger Verlauf der Transportzahnung 12 relativ zur Grundlinie 16 entspricht einem schrägen Verlauf der Transportzahnung 12 relativ zur Schneidkante 18 der Haarschneidmaschine. Dies hat den Vorteil, daß die nach links oder rechts abgeworfenen Haare nicht mehrfach an Zähnen 32 der Transportzahnung 12 in Abwurfrichtung beschleunigt werden und sorgt so für einen über eine breitere Querschnittsfläche verteilten Haarabwurf. Bei einem Haartransport nach links sind die rechts an der Transportzahnung 12 angeordneten Zähne 32 näher an der Schneidkante 18 der Haarschneidemaschine angeordnet, als die links an der Transportzahnung 12 angeordneten Zähne 36, wie in

Die Erfindung wurde anhand bevorzugter Ausführungsbeispiele erläutert, ohne auf diese Beispiele beschränkt zu sein. Einzelne Merkmale der jeweils dargestellten Ausführungsbeispiele sind auch untereinander kombinierbar oder mit anderen, gleichwirkenden Merkmalen austauschbar, sofern Kompatibilität vorliegt. So können beispielsweise die Zähne der Transportzahnung so ausgebildet sein, daß sich die Tangentialwinkel der flachen Flanken von der Grundlinie aus in Richtung auf die Spitze des einzelnen Zahns hin verringern, bis sie beispielsweise mit der Grundlinie einen Winkel von nahezu Null Grad aufweisen. Auch derart geformte Zahnprofile sollen in dieser Schrift als "sägezahnförmig" bezeichnet werden.The invention has been explained with reference to preferred embodiments, without being limited to these examples. Individual features of each illustrated embodiments are also combinable with each other or interchangeable with other, same-acting characteristics, provided compatibility is present. For example, the teeth of the feed teeth may be formed so that the tangential angles of the flat flanks are reduced from the baseline towards the tip of the single tooth until, for example, they have an angle of nearly zero degrees with the baseline. Also such shaped tooth profiles are to be referred to in this document as "sawtooth".
