Description

Die Erfindung betrifft ein elektrisches Haarschneidegerät nach dem Oberbergriff des Patentanspruchs 1.The invention relates to an electric hair trimmer according to the Oberbergriff of claim 1.

Aus der EP 0 752 298 A2 ist ein derartiges Gerät bekannt, wobei der schwenkbare Tragkörper ein einziges Schneidsystem trägt, das an dem der Schwenkachse gegenüberliegenden Ende des Tragkörpers angeordnet ist,From the EP 0 752 298 A2 Such a device is known, wherein the pivotable support body carries a single cutting system, which is arranged at the opposite end of the pivot axis of the support body,

Aus der WO 00/37225 ist ein Gerät bekannt, gemäß welchem ein Schneidkopf schwenkbar um eine Achse am Gehäuse des Gerätes gelagert ist, und wobei einem Schneidkamm, zwei Schneidklingen zugeordnet sind, welche jeweils in Abhängigkeit von der Schwenkstellung des Schneidkopfes mit einem Antriebselement des Antriebes koppelbar sind. Die jeweils andere Schneidklinge ist dann ausgekoppelt, so daß stets nur eine Schneideinheit angetrie-ben ist. Die Achse um welche der Schneidkopf schwenkbar ist, verläuft parallel zu den Schneidkanten der Schneidkämme bzw. Schneidklingen. Die Lagerung des Schneidkopfes erfolgt beidseitig durch eine gabelförmige Aufnahme im Gehäuse der Haarschneidemaschine. Die Schwenkachse verläuft zentral zu den beiden Schneidelementen. Die mit den Schneidelementen verbundenen Einkoppelelemente für den Exzenterantrieb weisen zwar schräge Erweiterungsabschnitte auf, um das Einführen des Exzenters in jeder Betriebsstellung zu erleichtern, jedoch ist vor dem Verschwenken der Schneidsysteme der Antrieb auszuschalten.From the WO 00/37225 a device is known, according to which a cutting head is pivotally mounted about an axis on the housing of the device, and wherein a cutting comb, two cutting blades are assigned, which in each case depending on the pivotal position of the cutting head with a drive element of the drive can be coupled. The respective other cutting blade is then decoupled, so that always only one cutting unit is driven ben. The axis about which the cutting head is pivotable, runs parallel to the cutting edges of the cutting combs or cutting blades. The storage of the cutting head is done on both sides by a fork-shaped receptacle in the housing of the hair clipper. The pivot axis is central to the two cutting elements. Although the coupling elements for the eccentric drive connected to the cutting elements have oblique extension sections in order to facilitate the insertion of the eccentric in each operating position, however, the drive is to be switched off before the pivoting of the cutting systems.

Die EP 1 216 799 A2 zeigt eine Haarschneidemaschine mit einem verdrehbar an der oberen Gehäusestirnseite gelagerten Doppelschersystem, wobei die Drehachse senkrecht zur durch die beiden Schersysteme aufgespannten Ebene verläuft.The EP 1 216 799 A2 shows a hair clipper with a rotatably mounted on the upper housing front side double shear system, wherein the axis of rotation is perpendicular to the plane defined by the two shear systems plane.

Aus der US 2003/0106219 A1 ist ein weiteres Haarschneidegerät bekannt, welches einen verschwenkbaren Schneidkopf mit zwei Schneidsystemen - einem schmaleren und einem breiteren - aufweist. Der Schneidkopf ist beidseitig in einem Gehäuse gelagert, wobei die Schwenkachse senkrecht zu einer durch die beiden Schneidsysteme gebildeten Ebene verläuft. Die Schwenkachse verläuft zentral zu den beiden Schneidelementen. Damit der Schneidkopf dieses Haarschneidegerätes auch bei einschaltetem Motor relativ zum Gehäuse verdreht werden kann, ist eine Kupplungseinrichtung vorgesehen, durch welche für diesen Verdrehvorgang die Antriebsverbindung zwischen Motor und Schersystem kurzfristig unterbricht.From the US 2003/0106219 A1 Another hair clipper is known, which has a pivotable cutting head with two cutting systems - a narrower and a wider - has. The cutting head is mounted on both sides in a housing, wherein the pivot axis is perpendicular to a plane formed by the two cutting systems. The pivot axis is central to the two cutting elements. So that the cutting head of this hair trimmer can be rotated relative to the housing even when the motor is switched on, a coupling device is provided, through which the drive connection between the engine and the shearing system temporarily interrupts for this turning process.

Beide bekannten Haarschneidegeräte verlangen vom Benutzer einen nicht unerheblichen Handhabungsaufwand zum Durchführen des Verschwenkens des Schneidkopfes. Insbesondere ist eine Einhandbedienung während des Verschwenkvorganges nicht möglich.Both known hair trimmers require the user a considerable handling effort to perform the pivoting of the cutting head. In particular, a one-hand operation during the pivoting process is not possible.

Der Erfindung liegt daher die Aufgabe zugrunde, die Bedienung eines drehbar an einem Gehäuse eines ein Kurzhaarschneidsystem aufweisenden Haarschneidegerätes gelagerten weiteren Schneidsystems deutlich zu verbessern; insbesondere soll eine Einhandbedienung ermöglicht werden.The invention is therefore based on the object clearly to improve the operation of a rotatably mounted on a housing of a hair clipper having a hair clipper further cutting system; In particular, a one-hand operation is to be made possible.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Durch die erfindungsgemäße Lösung läßt sich eine Anordnung schaffen, welche es dem Benutzer beispielsweis ermöglicht, mit dem Daumen der das Gerät umfassenden Hand das weitere Schneidsystem bei Bedarf um dessen Drehachse zu verschwenken, was den Bedienungskomfort eines derartigen Haarschneidegerätes enorm verbessert.This object is achieved by the features of claim 1. The inventive solution can create an arrangement which allows the user, for example, to pivot with the thumb of the device comprehensive hand, the further cutting system when needed about its axis of rotation, which greatly improves the ease of use of such a hair clipper.

Durch die Kombination des Schneidsystems mit einem Kurzhaarschneidsystem ist ein besonders vorteilhaftes Haarschneide- bzw. Rasiersystem geschaffen, wobei der Tragkörper drehbar an der Außenseite des Gehäuses eines ein Kurzhaarschneidsystem aufweisenden Rasiergerätes angeordnet ist. Das Kurzhaarschneidsystem dient dabei dem gründlichen Ausrasieren von Haaren, während das oder die im Tragkörper gelagertern Schneidsysteme als Langhaarschneider verschiedener Breite ausgebildet sein können. Diese Systeme lassen sich dann bei Einhandbedienung auf einfache Weise in ihre Betriebsstellung verschwenken.By combining the cutting system with a short hair cutting system, a particularly advantageous hair cutting or shaving system is provided, wherein the support body is rotatably disposed on the outside of the housing of a shaving device having a short hair cutting system. The short-hair cutting system serves to thoroughly shave hair, while the one or more stored in the support body cutting systems can be designed as long-hair trimmer different width. These systems can then be easily pivoted in one-handed operation in their operating position.

Ist ein Antriebsmittel zum Betätigen des mindestens einen Schneidsystems derart angeordnet, daß es das zu bewegende Scherelement bzw. ein mit diesem verbundenes Bauteil im unmittelbaren Bereich der Drehachse beaufschlagt, so wird es ermöglicht, das Schneidsystem auch bei eingeschaltetem Antrieb zu verschwenken. Dies verbessert die Handhabung noch weiter.If a drive means for actuating the at least one cutting system is arranged such that it acts on the shearing element to be moved or a component connected thereto in the immediate region of the axis of rotation, it is possible to pivot the cutting system even when the drive is switched on. This improves handling even further.

Das Schneidsystem weist vorteilhafterweise einen Schneidkamm mit zugeordneter Schneidklinge auf, so daß es als Haartrimmer bzw. Langhaarschneider verwendet werden kann. Sowohl der Schneidkamm als auch die Schneidklinge weisen dabei Verzahnungen auf, deren Flanken die Schneidkanten bilden.The cutting system advantageously has a cutting comb with associated cutting blade, so that it can be used as a hair trimmer or long-hair trimmer. Both the cutting comb and the cutting blade in this case have teeth whose edges form the cutting edges.

Eine bevorzugte Weiterbildung der Erfindung sieht vor, daß zwei diametral gegenüberliegende Schneidsysteme im Tragkörper gelagert sind, wobei vorteilhafterweise die Drehachse außermittig bezüglich dieser beiden Schneidsysteme verläuft. Somit läßt sich beim Verschwenken des Tragkörpers relativ zum Gehäuse des Haarschneidegerätes sowohl das anzuwendende Schneidsystem wechseln, als auch die Relativlage des Schneidsystems zum Gehäuse verändern.A preferred embodiment of the invention provides that two diametrically opposed cutting systems are mounted in the support body, wherein advantageously the axis of rotation extends eccentrically with respect to these two cutting systems. Thus, when pivoting the support body relative to the housing of the hair trimmer, both the cutting system to be used can be changed, as well as the relative position of the cutting system to the housing change.

Vom besonderen Vorteil ist es dabei, wenn zwei voneinander unterschiedliche Schneidsysteme vorhanden sind, die dann in entsprechendem Betriebszustand jeweils eine geeignete Position relativ zum Gehäuse des Haarschneidegerätes aufweisen. Auf vorteilhafte Weise lassen sich so insbesondere zwei Langhaarschneidsysteme jeweils bestehend aus einem Schneidkamm und einer zugeordneten Schneidklinge ausbilden, welche jeweils eine unterschiedliche Breitenerstreckung besitzen. Somit läßt sich ein relativ breit ausgeführter Langhaarschneider zum Kürzen längerer Haare mit einem schmaleren Konturenschneider zum Schneiden feinerer Konturen kombinieren und durch entsprechendes Verschwenken des Tragkörpers in Arbeitsposition bringen. In Kombination mit der unsymmetrischen Lage der beiden Schneidsysteme in Bezug auf die gemeinsame Drehachse läßt sich dann beispielsweise der Konturenschneider beim Verschwenken in die Arbeitsposition in eine gegenüber dem Gehäuse besonders exponierte Lage bewegen, wodurch der Arbeitsbereich für dieses Schneidwerkzeug für den Benutzer besonders gut einsehbar und nicht durch das Gehäuse oder damit verbundene Teile verdeckt ist.It is of particular advantage when two different cutting systems are present, which then each have a suitable position relative to the housing of the hair trimmer in the corresponding operating state. In an advantageous manner, in particular two long-hair trimmer systems can be formed, each consisting of a cutting comb and an associated cutting blade, which each have a different width extension. Thus, a relatively wide executed long-hair trimmer for shortening longer hair can be combined with a narrower contour cutter for cutting finer contours and bring by appropriate pivoting of the support body in working position. In combination with the asymmetrical position of the two cutting systems with respect to the common axis of rotation, for example, the contour cutter when pivoting in the working position in a position particularly exposed to the housing move, making the work area for this cutting tool for the user particularly visible and not is covered by the housing or related parts.

Die beiden Schneidsysteme werden vorteilhafterweise durch gemeinsame Antriebsmittel betätigt, was den Konstruktions- und Montageaufwand gering hält.The two cutting systems are advantageously operated by common drive means, which keeps the construction and assembly costs low.

Vorteilhafterweise werden dabei sowohl das Kurzhaarschneidsystem als auch die im Tragkörper gelagerten Scherelemente von einem gemeinsamen Motor angetrieben.Advantageously, both the short hair cutting system and the shear elements mounted in the supporting body are driven by a common motor.

Eine besondere Flexibilität in Bezug auf die Positionierung der Schneidelemente relativ zum Gehäuse des Haarschneidegerätes läßt sich realisieren, wenn der Tragkörper linear verschiebbar am Gehäuse gelagert ist, so daß auf einfache Weise auch weit auseinanderlie-gende Betriebspositionen ansteuerbar sind. Zwar sind beispielsweise aus der DE 43 36 231 C1 längsverschiebbare Langhaarschneidsysteme bekannt, diese sind jedoch nicht um eine Achse schwenkbar gelagert.A particular flexibility with respect to the positioning of the cutting elements relative to the housing of the hair trimmer can be realized if the support body is mounted linearly displaceable on the housing, so that in a simple way far apart-lying operating positions can be controlled. Although, for example, from the DE 43 36 231 C1 longitudinally displaceable long hair cutting systems known, but these are not pivotally mounted about an axis.

Zur Erhöhung des Bedienungskomforts ist es auch möglich, die Linear- und/oder Rotationsbewegungen des Tragkörpers elektromotorisch zu betreiben.To increase the ease of use, it is also possible to operate the linear and / or rotational movements of the support body by an electric motor.

Die perspektivische Darstellung gemäß Fig. 1 zeigt einen an sich bekannten Trockenrasierer 1 mit einem Gehäuse 2 und einem Kurzhaarschneidsystem 3. Das Kurzhaarschneidsystem besteht aus einem als Scherfolie ausgebildeten Obermesser 4 unter dem ein zeichnerisch nicht dargestelltes Untermesser oszillierend hin- und herbewegt wird. Das Gehäuse nimmt den hierzu benötigten Antriebsmotor sowie ggf. elektrische Speicherzellen und/oder ein Netz- und Ladeteil zur Energieversorgung des Antriebsmotors auf. Auf der Rückseite des Gehäuses 2 ist ein Ein-/Aus-Schalter 5 angeordnet. Durch diesen wird die Energieversorgung des Antriebsmotors geschaltet, der in eingeschaltetem Zustand sowohl das nicht dargestellte Untermesser des Kurzhaarschneidsystems 3 oszillierend antreibt als auch dem permanenten Antrieb eines aus dem Gehäuse 2 herausragenden Antriebselementes 6 dient. Das Antriebselement 6 wird dabei wie das Untermesser oszillierend parallel zur Querachse des Trockenrasierers angetrieben.The perspective view according to Fig. 1 shows a known dry shaver 1 with a housing 2 and a Kurzhaarschneidsystem 3. The Kurzhaarschneidsystem consists of a trained as a shear foil upper blade 4 under which a graphically not shown lower blade is oscillated back and forth. The housing accommodates the drive motor required for this purpose, as well as possibly electrical storage cells and / or a mains and charging unit for supplying power to the drive motor. On the back of the housing 2, an on / off switch 5 is arranged. By this, the power supply of the drive motor is switched, which drives the unillustrated lower blade of Kurzhaarschneidsystems 3 in the on state oscillating and the permanent drive of a protruding from the housing 2 drive element 6 is used. The drive element 6 is driven as the lower blade oscillating parallel to the transverse axis of the dry shaver.

Auf der Vorderseite des Gehäuses 2 ist ein Schiebeschalter 7 angeordnet, auf dem der Tragkörper 8 gelagert ist, in welchem ein erstes und ein zweites Langhaarschneidesystem 9 bzw. 10 angeordnet ist. Der Schiebeschalter 7 ist entlang der Längsachse des Gehäuses 2 verschiebbar gelagert. Der Tragkörper 8 wiederum ist schwenkbar um die Drehachse 11 auf dem Schiebeschalter 7 gelagert. Die Drehachse 11 steht im wesentlichen senkrecht auf der Vorderseite des Gehäuses. Die Linearverschiebbarkeit des Scheibeschalters auf dem Gehäuse 2 wird durch an sich bekannte Maßnahmen wie schlittenartige Längsführungen realisiert. Diese sind zeichnerisch nicht näher dargestellt.On the front of the housing 2, a slide switch 7 is arranged, on which the support body 8 is mounted, in which a first and a second long-hair cutting system 9 and 10 is arranged. The slide switch 7 is slidably mounted along the longitudinal axis of the housing 2. The support body 8 in turn is pivotally mounted about the axis of rotation 11 on the slide switch 7. The axis of rotation 11 is substantially perpendicular to the Front of the case. The linear displacement of the Scheibeschalters on the housing 2 is realized by known measures such as carriage-like longitudinal guides. These are not shown in the drawing.

Der Aufbau der vormontierbaren Baueinheit aus Schiebeschalter 7 und Tragkörper 8 geht deutlich aus den Fig. 7 bis 9 hervor. Der Schiebeschalter 7 besteht im wesentlichen aus der Basisplatte 12 und der Abdeckschale 13, welche mit Griffmulden 14 versehen ist. Die Basisplatte 12 dient der längsverschiebbaren Lagerung auf dem Gehäuse 2; zwischen der Basisplatte 12 und der Abdeckschale 13 ist eine U-förmige Bügelfeder 15 vorgesehen. Ein Doppelhebel 16 wird auf der Basisplatte 12 montiert, hierzu weist die Basisplatte eine Lagerstelle 17 auf, die der drehbaren Lagerung des Doppelhebels 16 an dessen zentralem Schwenklager 18 dient. Am oberen Ende des Doppelhebels 16 ist ein sich quer in Richtung auf die Abdeckschale 13 erstreckender Antriebsstift 19 angeordnet, während am unteren Ende sich ebenfalls quer erstreckende Kupplungswangen 20 ausgebildet sind, die jedoch in entgegengesetzter Richtung, also zum Gehäuse 2 hin verlaufen. Dabei durchragen die Kupplungswangen 20 die ovale Ausnehmung 21, die in der Basisplatte 12 vorgesehen ist. Im oberen Drittel der Abdeckschale 13 ist ein kreisrunder Ausschnitt 22 vorgesehen, der in montiertem Zustand den Antriebsstift 19 umgibt. Der Ausschnitt 22 verläuft konzentrisch um den Antriebsstift 19, wenn sich der Doppelhebel 16 in der in den Figuren 7 bis 9 dargestellten Mittellage befindet. Der Ausschnitt 22 wird von einem umlaufenden Bund 23 begrenzt, welcher der Lagerung der Montageplatte 24 dient. Die Montageplatte 24 weist einen Kreisausschnitt 25 auf, dessen Durchmesser dem des Ausschnittes 22 entspricht. Die Montageplatte 24 und die Abdeckschale 13 werden durch das Drehgelenk 26 verschwenkbar miteinander verbunden. Das Drehgelenk 26 besteht aus einem Lagerring 27, an dem zwei sich diametral gegenüberliegende axial erstreckende Montagedome 28 ausgebildet sind. Während die Montageplatte 24 auf der Abdeckschale 13 vorderseitig am Bund 23 anliegt, kontaktiert der Lagerring 27 den Bund 23 auf der Rück- bzw. Innenseite der Abdeckschale 13. Die Montagedome 28 durchragen dabei sowohl den Ausschnitt 22 als auch den Kreisausschnitt 25 und dienen zuammen mit einem umlaufenden Absatz der Zentrierung von Abdeckschale 13 und Montageplatte 24.The structure of the preassembled unit of slide switch 7 and support body 8 is clear from the Fig. 7 to 9 out. The slide switch 7 consists essentially of the base plate 12 and the cover shell 13, which is provided with recessed grips 14. The base plate 12 serves for longitudinally displaceable mounting on the housing 2; between the base plate 12 and the cover shell 13, a U-shaped bow spring 15 is provided. A double lever 16 is mounted on the base plate 12, for this purpose, the base plate has a bearing 17, which serves for the rotatable mounting of the double lever 16 at its central pivot bearing 18. At the upper end of the double lever 16 is a transversely extending in the direction of the cover 13 extending drive pin 19, while at the lower end also transversely extending coupling cheeks 20 are formed, but extend in the opposite direction, ie to the housing 2 out. The coupling cheeks 20 protrude through the oval recess 21 which is provided in the base plate 12. In the upper third of the cover shell 13, a circular cutout 22 is provided, which surrounds the drive pin 19 in the assembled state. The cutout 22 extends concentrically around the drive pin 19 when the double lever 16 in the in the FIGS. 7 to 9 is shown center position. The cutout 22 is bounded by a circumferential collar 23, which serves to support the mounting plate 24. The mounting plate 24 has a circular cutout 25 whose diameter corresponds to that of the cutout 22. The mounting plate 24 and the cover 13 are pivotally connected to each other by the hinge 26. The rotary joint 26 consists of a bearing ring 27 on which two diametrically opposed axially extending mounting domes 28 are formed. While the mounting plate 24 rests on the cover shell 13 on the front side of the collar 23, the bearing ring 27 contacts the collar 23 on the rear or inside of the cover 13. The mounting domes 28 protrude through both the cutout 22 and the circular cutout 25 and serve together with a circumferential shoulder of the centering of cover shell 13 and mounting plate 24th

Die Montagedome 28 weisen jeweils zwei axial verlaufende Bohrungen auf, die der Aufnahme von entsprechenden Befestigungsstiften dienen, die auf der Innenseite des Deckels 29 des Tragkörpers 8 vorgesehen sind. Der Tragkörper 8 setzt sich somit aus dem Deckel 29 und der Montageplatte 24 zusammen.The mounting domes 28 each have two axially extending bores which serve to receive corresponding fastening pins which are provided on the inside of the cover 29 of the support body 8. The support body 8 is thus composed of the lid 29 and the mounting plate 24 together.

Wie bereits anhand von Fig. 1 erwähnt, sind im Tragkörper 8 die beiden Langhaarschneidsysteme 9 und 10 integriert. Diese befinden sich zwischen der Montageplatte 24, und dem Deckel 29 und sind durch den das Drehgelenk 26 durchgreifenden Antriebsstift 19 antreibbar. Das erste Langhaarschneidsystem 9 besteht aus einem feststehenden Schneidkamm 30 und einer linear oszillierenden Schneidklinge 31, wobei sowohl Schneidkamm als auch Schneidklinge eine gerade verlaufende Zahnreihe aufweisen. Die Flanken der Schneidzähne bilden somit Schneidkanten, die dazwischengeratene Haare schneiden. Der Schneidkamm 30 weist Langlöcher 32 auf, in welche Führungsstifte 33 hineinragen und eine Linearlagerung bilden. Die Schneidklinge 31 besitzt einen Kupplungsabschnitt 34, der eine Aufnahme 35 für den Antriebsstift 19 aufweist. Die Aufnahme 35 ist als sich vertikal erstreckendes Langloch ausgebildet.As already on the basis of Fig. 1 mentioned, the two Longhaarschneidsysteme 9 and 10 are integrated in the support body 8. These are located between the mounting plate 24, and the lid 29 and are driven by the pivot pin 26 by cross-drive pin 19. The first long hair cutting system 9 consists of a fixed cutting comb 30 and a linearly oscillating cutting blade 31, wherein both cutting comb and cutting blade have a straight row of teeth. The flanks of the cutting teeth thus form cutting edges, the intervening hair cut. The cutting comb 30 has elongated holes 32, in which guide pins 33 protrude and form a linear bearing. The cutting blade 31 has a coupling portion 34 which has a receptacle 35 for the drive pin 19. The receptacle 35 is formed as a vertically extending slot.

Das zweite Langhaarschneidsystem 10, welches weniger als halb so breit ausgeführt ist, wie das erste Langhaarschneidsystem, besteht aus einem feststehenden Schneidkamm 36 und einer schwenkbar oszillierend angetriebenen Schneidklinge 37. Die Zahnreihen dieser beiden Schneidelemente sind gerundet ausgeführt, wobei ihr Krümmungsradius etwa um den Schwenkpunkt 38 des an der Schneidklinge 37 angeformten Antriebshebels 39 liegt. An dem der Schneidklinge 37 gegenüberliegenden Ende des Antriebshebels 39 ist ebenfalls eine Aufnahme 40 für den Antriebsstift 19 als vertikal verlaufendes Langloch ausgebildet. Der Schwenkpunkt 38 wird durch einen am Deckel 29 innen angeformten Lagerstrft 41 gebildet. Auch die beiden Schneidkämme 30 und 36 sind auf der Innenseite des Deckels 29 befestigt.The second long-hair trimmer 10, which is made less than half as wide as the first long-hair trimmer, consists of a fixed cutting comb 36 and a pivotally oscillating driven cutting blade 37. The rows of teeth of these two cutting elements are rounded, with their radius of curvature about the pivot point 38th of the integrally formed on the cutting blade 37 drive lever 39 is located. At the opposite end of the cutting blade 37 of the drive lever 39, a receptacle 40 for the drive pin 19 is also formed as a vertically extending slot. The pivot point 38 is formed by a lid 29 on the inside formed Lagerstrft 41. The two cutting combs 30 and 36 are mounted on the inside of the lid 29.

Die Schneidklingen 31 und 37 befinden sich zwischen den jeweils zugeordneten Schneidkämmen und der Montageplatte 24. Ihre Zahnreihen werden von denen der zugeordneten Schneidkämme geringfügig überragt, so daß für den Benutzer keine Verletzungsgefahr durch die angetriebenen Teile besteht.The cutting blades 31 and 37 are located between the respective associated cutting combs and the mounting plate 24. Your rows of teeth are slightly surmounted by those of the associated cutting combs, so that there is no risk of injury to the user by the driven parts.

Sobald der Doppelhebel 16 - wie später noch beschrieben wird - schwingend angetrieben wird, sind die beiden Schneidklingen 31 und 37 in oszillierender Bewegung, da sie beide in Eingriff mit dem Antriebsstift stehen. Durch entsprechendes Verschwenken des Tragkörpers 8 können die beiden Langhaarschneidsysteme 9 bzw. 10 in die gewünschte Arbeitsposition gebracht werden. Hierzu muß der Antrieb nicht abgeschaltet oder ausgekuppelt werden, sondern der um das Schwenklager 18 schwingende Antriebsstift 19 kann aufgrund seiner Zentrierung bezüglich des Drehgelenkes 26 problemlos die beiden Schneidklingen 31 bzw. 37 weiter antreiben bzw. sich in den Aufnahmen 35 und 40 bewegen.Once the double lever 16 - as will be described later - is driven swinging, the two cutting blades 31 and 37 are in oscillating motion, since they are both in engagement with the drive pin. By appropriate pivoting of the support body 8, the two long-hair trimmer 9 and 10 can be brought into the desired working position. For this purpose, the drive must not be turned off or disengaged, but the oscillating about the pivot bearing 18 driving pin 19 can due to its centering with respect to the pivot 26 easily the two cutting blades 31 and 37 continue to drive or move in the receptacles 35 and 40.

Wird der Tragkörper 8 aus der in Fig. 8 dargestellten Ausgangslage - erstes Langhaarschneidsystem 9 ist oben und zweites Langhaarschneidsystem 10 ist unten liegend - um 90° verschwenkt, so nimmt die Amplitude der Bewegungen der Schneidklingen 31 bzw. 37 permanent bis auf den Wert 0 ab, da bei einer 90° Verschwenkung gegenüber der Ausgangslage die Erstreckungen der Aufnahmen 35 und 40 mit der Schwingbewegung des Antriebsstiftes 19 übereinstimmen und sich dieser lediglich in den Aufnahmen frei hin- und herbewegt. Wird die Schwenkbewegung des Tragkörpers 8 weiter geführt, also von 90° auf 180° weitergeschwenkt, so nimmt die Schwingamplitude der Schneidklingen 31 und 37 wieder zu, bis sie bei der Verschwenkung um 180° ihren Maximalwert wieder angenommen haben.If the support body 8 from the in Fig. 8 illustrated initial position - first long-hair trimmer 9 is above and second long-hair trimmer 10 is down - pivoted by 90 °, so the amplitude of the movements of the cutting blades 31 and 37 decreases permanently down to the value 0, as at a 90 ° pivoting relative to the starting position the extensions of the receptacles 35 and 40 coincide with the oscillatory movement of the drive pin 19 and this freely reciprocates only in the images. If the pivoting movement of the supporting body 8 continues to be guided, ie pivoted further from 90 ° to 180 °, the amplitude of oscillation of the cutting blades 31 and 37 increases again until they have returned to their maximum value when pivoting by 180 °.

Zur Arretierung des Tragkörpers 8 in den beiden bevorzugten Arbeitspositionen, die in den Figuren 1 bis 6 auch dargestellt sind, sind am Lagerring 27 des Drehgelenkes 26 zwei sich radial erstreckende überstehende Nocken 42 ausgebildet, welche in diesen genannten Arbeitspositionen mit den entsprechenden Ausbauchungen 43 verrasten, die an jeweils einem Schenkel der Bügelfeder 15 ausgebildet sind. Da sich das Drehgelenk 26 mit dem Tragkörper 8 mit verdreht, können beim Verdrehen des Tragkörpers 8 die Nocken 42 leichtgängig unter elastischer Verformung der Bügelfeder 15 in die Ausbauchungen 43 einrasten bzw. entrastet werden.For locking the support body 8 in the two preferred working positions, in the FIGS. 1 to 6 are also shown, two radially extending projecting cam 42 are formed on the bearing ring 27 of the rotary joint 26, which engage in said working positions with the corresponding bulges 43 which are formed on each leg of the bow spring 15. Since the rotary joint 26 is rotated with the support body 8, the cams 42 can easily engage with the elastic deformation of the bow spring 15 into the bulges 43 or be unlocked when the support body 8 is rotated.

Die Figuren 1 und 2 zeigen den Trockenrasierer 1 in seiner Ausgangsstellung. Durch Betätigen des Ein-/Aus-Schalters 5 wird der Motor in Gang gesetzt und das nicht dargestellte Untermesser unter der Scherfolie 4 oszillierend angetrieben. Gleichzeitig bewegt sich das Antriebselement 6, welches leicht aus dem Gehäuse 2 des Trockenrasierers herausragt, oszillierend quer zum Gehäuse, also in der gleichen Richtung wie die Untermesser. Mit dem Kurzhaarschneidsystem 3 können in diesem Zustand Haare ausrasiert werden, die beiden Langhaarschneidsysteme 9 und 10 werden nicht angetrieben, d.h. die Schneidklingen 31 bzw. 37 führen keine Bewegung relativ zu den zugeordneten Schneidkämmen 30 bzw. 36 aus. Das erste Langhaarschneidsystem 9 liegt tiefer als das Kurzhaarschneidsystem 3 und gibt die Sicht auf dessen Arbeitsbereich frei.The Figures 1 and 2 show the dry shaver 1 in its initial position. By pressing the on / off switch 5, the motor is set in motion and the lower blade, not shown, driven under the shear foil 4 oscillating. At the same time, the drive element 6, which protrudes slightly from the housing 2 of the dry shaver, oscillates transversely to the housing, ie in the same direction as the lower blade. With the short-hair trimmer 3 hair can be shaved in this state, the two long-hair trimmers 9 and 10 are not driven, ie the cutting blades 31 and 37 perform no movement relative to the associated cutting combs 30 and 36 respectively. The first long-hair trimmer 9 lies lower than the short-hair trimmer 3 and releases the view of its working area.

Wird nun der Schiebeschalter 7 um den Weg X in Längsrichtung des Gehäuses 2 relativ zu letzterem nach oben verschoben, so gelangt das Antriebselement 6 zwischen die Kupplungswangen 20 des Doppelhebels 16. Mit Erreichen dieser durch entsprechende Anschläge am Gehäuse 2 und Schiebeschalter 7 vorhandenen Anschläge definierten Weges X schwingt der Doppelhebel 16 angetrieben durch das Antriebselement 6 um die Lagerstelle 17 bzw. das Schwenklager 18. In diesem zweiten Betriebszustand des Haarschneidegerätes führt die Schneidklinge 31 eine oszillierende Linearschwingung relativ zum Schneidkamm 30 aus; die Schneidklinge 37 schwingt rotierend oszillierend relativ zum Schneidkamm 36 um den Schwenkpunkt 38. In diesem zweiten Betriebszustand ist das erste, breit ausgelegte Langhaarschneidsystem 9 nach oben gerichtet und überragt in der Höhe das Kurzhaarschneidsystem 3. Mit dem ersten Langhaarschneidsystem 9 können nun beispielsweise längere Haare entfernt oder vorgeschnitten werden, um dann anschließend besser durch das Kurzhaarschneidsystem 3 erfaßt und ausrasiert werden zu können. Durch die exponierte Stellung des ersten Langhaarschneidsystems 9 kann dieses sehr gut eingesehen und angewendet werden.Now, if the slide switch 7 shifted by the distance X in the longitudinal direction of the housing 2 relative to the latter up, the drive element 6 passes between the coupling cheeks 20 of the double lever 16. With reaching this by corresponding stops on the housing 2 and slide switch 7 existing attacks defined way X of the double lever 16 driven by the drive member 6 swings about the bearing point 17 and the pivot bearing 18. In this second operating state of the hair trimmer, the cutting blade 31 performs an oscillating linear vibration relative to the cutting comb 30; the cutting blade 37 oscillates in a rotationally oscillating manner relative to the cutting comb 36 about the pivot point 38. In this second operating state, the first, broad-cut long-hair trimmer 9 is directed upwards and towers above the short-hair trimmer 3. With the first trimmer 9, for example, longer hairs can be removed or be pre-cut, in order then then better to be detected and shaved by the Kurzhaarschneidsystem 3 can. Due to the exposed position of the first long-hair trimmer 9, this can be very well viewed and applied.

Die Figuren 5 und 6 zeigen einen Betriebszustand, bei welchem das zweite Langhaarschneidsystem 10 in eine optimale Arbeitsposition gebracht ist. Auch in diesem Betriebszustand ist der Schiebeschalter 7 in seiner oberen Schaltposition, entsprechend Fig. 3 und 4, jedoch ist der Tragkörper 8 und damit auch die in ihm integrierten Schneidelemente gegenüber dem zweiten Betriebszustand um 180° gegenüber dem Schiebeschalter 7 bzw. dem Gehäuse 2 um die Drehachse 11 verschwenkt. Das zweite, schmaler ausgeführte Langhaarschneidsystem 10, das sich nun in Arbeitsposition befindet, dient dem Schneiden feiner Konturen, beispielsweise bei Bartträgern. Da die Drehachse 11 exzentrisch bezüglich der Lage der beiden Langhaarschneidsysteme 9 und 10 ist und da der Abstand des zweiten Langhaarschneidsystems 10 von der Drehachse 11 etwa doppelt so groß ist wie der Abstand zwischen Drehachse 11 und dem ersten Langhaarschneidsystem 9, überragt das als Styler ausgebildete zweite Langhaarschneidsystem 10 in dem in den Figuren 5 und 6 dargestellten dritten Betriebszustand das Kurzhaarschneidsystem 3 noch deutlicher als es das erste Langhaarschneidsystem 9 in dem zweiten Betriebszustand, der in den Fig. 3 und 4 dargestellt ist, tut. Dadurch ist die Einsehbarkeit bei Benutzung des zweiten Langhaarschneidsystems noch besser als sie es schon ist, wenn das erste Langhaarschneidsystem 9 in Einsatz ist.The FIGS. 5 and 6 show an operating state in which the second long-hair cutting system 10 is brought into an optimal working position. Also in this operating state, the slide switch 7 is in its upper switching position, accordingly 3 and 4 However, the support body 8 and thus also the cutting elements integrated in it compared to the second operating state by 180 ° relative to the slide switch 7 and the housing 2 is pivoted about the axis of rotation 11. The second, narrower long-hair trimmer 10, which is now in working position, is used to cut fine contours, for example, beards. Since the axis of rotation 11 is eccentric with respect to the position of the two long hair cutting systems 9 and 10 and since the distance of the second long-hair trimmer 10 from the axis of rotation 11 is about twice as large as the distance between the axis of rotation 11 and the first long-hair trimmer 9, the styler designed as the second Long hair trimmer 10 in which in the FIGS. 5 and 6 illustrated third operating state, the Kurzhaarschneidsystem 3 even more clearly than it is the first long-hair trimmer 9 in the second operating state, in the 3 and 4 is shown, does. As a result, the visibility when using the second long-hair trimmer system is even better than it already is when the first long-hair trimmer system 9 is in use.

In einer zeichnerisch nicht dargestellten Ausführung ist vorgesehen, daß die Schwenkbewegung des Tragkörpers 8 und/oder die Längsverschiebung des Schiebeschalter durch geeignete Stellantriebe erfolgt, die durch den Benutzer über entsprechende Schaltelemente gesteuert werden.In a drawing, not shown, it is provided that the pivoting movement of the support body 8 and / or the longitudinal displacement of the slide switch is effected by suitable actuators, which are controlled by the user via corresponding switching elements.
