Description

Die Erfindung betrifft einen Schwingungsantrieb für Geräte und Werkzeuge, wie er im einleitenden Teil des Anspruchs 1 angegeben ist.The invention relates to a vibration drive for devices and tools, as specified in the introductory part of claim 1.

Der Antrieb eines Werkzeuges od. dgl. mittels oder unter Mitwirkung einer schwingend bewegten motorisch angetriebenen Masse bringt nicht nur eine Vereinfachung des Gerätes mit sich, sondern kann oftmals auch zu einer wesentlichen Verminderung der Motorantriebsleistung führen.Driving a tool or the like by means of or with the cooperation of a vibrating, motor-driven mass not only simplifies the device, but can often also result in a significant reduction in the motor drive power.

Ein Schwingungsantrieb der genannten Art ist beispielsweise bei dem in der EP-A-0 012 129 dargestellten Reinigungsgerät vorgesehen. Bei diesem ist das Werkzeug über einen Werkzeugträger am Ende eines als Antriebsteil bezeichneten Verbindungsteils mitschwingbar verbunden, welches seinerseits an dem einen Schwunggewicht zugewendeten Ende des Motorgehäuses befestigt ist. Gemäß dem dort zeichnerisch dargestellten Ausführungsbeispiel ist die aus den genannten Teilen bestehende Einheit an dem dem Schwunggewicht abgewendeten Ende pendelartig gehalten und im Bereich des Schwunggewichtes elastisch im Gerätegehäuse abgestützt, womit zweifellos Vorteile hinsichtlich einer Druckbelastung für die schwingende Einheit gegeben sind. Das Werkzeug wird dort infolge der Pendellagerung in eine kreisförmig pendelnde Umlaufbahn angetrieben. Es sind dabei auch Maßnahmen vorgesehen, um diese Antriebsbewegung in eine mehr oder weniger flach elliptische Umlaufbahn umzulenken. Wegen der Baulänge des Motors wird eine Antriebsbewegung mit großer Amplitude erzeugt, die nicht überall erforderlich ist.A vibration drive of the type mentioned is provided, for example, in the cleaning device shown in EP-A-0 012 129. In this case, the tool is connected to a tool carrier at the end of a connecting part referred to as the drive part, which in turn is fastened to the end of the motor housing facing a swing weight. According to the exemplary embodiment shown there, the unit consisting of the parts mentioned is held in a pendulum-like manner at the end facing away from the swinging weight and is elastically supported in the area of the swinging weight in the device housing, which undoubtedly gives advantages with regard to a pressure load for the vibrating unit. As a result of the self-aligning bearing, the tool is driven into a circularly oscillating orbit. Measures are also provided to divert this drive movement into a more or less flat elliptical orbit. Because of the length of the motor, a drive movement with a large amplitude is generated, which is not required everywhere.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung geht von einem Schwingungsantrieb der anfangs genannten Art aus und ist im Anspruch 1 gekennzeichnet.The invention seeks to remedy this. The invention is based on a vibration drive of the type mentioned at the outset and is characterized in claim 1.

Die durch die Erfindung erreichten Vorteile sind daher im wesentlichen in bisher nicht möglichen weiteren Anwendungen des eingangs genannten Schwingungsantriebs zu sehen. Der besondere Vorteil der Erfindung ist darin gelegen, daß mittels einer schwingend bewegten Masse eine parallel zu einer Ebene gerichtete und/oder auch hin- und herschwingende Werkzeugbewegung unabhängig von deren Schwinglagerung auf ein Werkzeug od. dgl. übertragbar ist.The advantages achieved by the invention can therefore be seen essentially in further applications of the vibration drive mentioned at the outset which have not been possible until now. The particular advantage of the invention is that by means of an oscillating mass, a tool movement directed parallel to a plane and / or also oscillating to and fro can be transferred to a tool or the like independently of its oscillating bearing.

Durch weitere, in den abhängigen Ansprüchen dargestellte Maßnahmen werden gegenüber der bisher bekannten Ausbildung zusätzliche Vorteile erzielt.Additional measures shown in the dependent claims achieve additional advantages over the previously known design.

So kann z. B. gemäß einer bevorzugten Ausführungsform der Erfindung vorgesehen sein, daß das Verbindungsteil mit dem vom Schwunggewicht und/oder Exzenter abgewendeten Eten des Motorgehäuses verbunden ist und in einer vorzugsweise pendelartige Schwingbewegungen der Antriebseinheit zulassenden Halterung im Gerätegehäuse lagert, wobei der Motor über das vorzugsweise in der Halterung lagernde Verbindungsteil hebelartig auf das Werkzeug oder den Werkzeugträger einwirkt. Diese erfindungsgemäße Maßnahme ist nicht nur bei Rasierapparaten, sondern auch bei anderen Antrieben von Bedeutung, weil damit auch Schwingungen mit geringen Amplituden kraftvoll mittels einer schwingend bewegten Masse übertragen werden können. Bei der eingangs genannten bekannten Ausbildung eines solchen Schwingungsantriebes ist dies wegen des grossen Abstandes zwischen dem Werkzeug und seiner Pendellagerung nicht möglich. Die Antriebseinheit kann dabei von einem Schwunggewicht und/oder einem Exzenter schwingend angetrieben sein und wird, je nach Ausbildung der Schwinglagerung eine kreisförmige bis flach ellyptische Taumelbewegung ausführen. Auch diese Antriebsbewegung kann erfindungsgemäß geradlinig und erforderlichenfalls auch hin- und herschwingend auf ein Werkzeug oder einen Werkzeugträger übertragen werden.So z. B. according to a preferred embodiment of the invention that the connecting part is connected to the Eten of the motor housing facing away from the flywheel weight and / or eccentric and is mounted in a preferably pendulum-like oscillating movements of the drive unit in the holder housing, the motor via which preferably in the Bracket-mounted connecting part acts lever-like on the tool or the tool holder. This measure according to the invention is important not only in the case of shavers, but also in the case of other drives, because it enables vibrations with low amplitudes to be transmitted powerfully by means of an oscillating mass. In the known design of such a vibration drive mentioned at the beginning, this is not possible because of the large distance between the tool and its self-aligning bearing. The drive unit can be driven in a swinging manner by a swing weight and / or an eccentric and, depending on the design of the swing bearing, will execute a circular to flat elliptical wobble movement. This drive movement can also be transmitted according to the invention in a straight line and, if necessary, also swinging back and forth to a tool or a tool carrier.

Dabei kann auch vorgesehen sein, daß zum Schwingantrieb der Antriebseinheit ein an der Motorwelle angeordneter Exzenter in eine zumindest mittelbar im bzw. am Gerätegehäuse senkrecht zur oszillierenden Schwinglagerung des Werkzeuges bzw. Werkzeugträgers angeordnete Schlitzführung eingreift. Nachdem dadurch auch das Drehmoment der Motorwelle eine direkte Antriebsübertragung ausübt, kann im Zusammenwirken mit der schwingend bewegten Umwuchtmasse eine besonders wirksame Antriebsbewegung zustande kommen. Auch diese ist gemäß der Erfindung geradlinig und gegebenenfalls hin- und herschwingend auf ein Werkzeug o. dgl. übertragbar.It can also be provided that for the oscillation drive of the drive unit an eccentric arranged on the motor shaft engages in a slot guide arranged at least indirectly in or on the device housing perpendicular to the oscillating oscillating bearing of the tool or tool carrier. Since the torque of the motor shaft also exerts direct drive transmission, a particularly effective drive movement can occur in cooperation with the oscillating moving balancing mass. According to the invention, this is also straightforward and, if appropriate, can be transferred back and forth to a tool or the like.

Die übrigen Ansprüche der Erfindung betreffen im wesentlichen Maßnahmen zur Schwinglagerung der Antriebseinheit. Insbesondere werden damit dem Verbindungsteilende der Antriebseinheit eine flach ellyptische bis hin- und herschwingende Pendelbewegung übermittelt, sodaß die Gleitführung eines am Gerätegehäuse hin- und herbewegbar gelagerten Werkzeuges weniger stark belastet wird. Damit werden auch Verkantungen in der Gleitführung vermieden und die Lebensdauer derselben verlängert.The remaining claims of the invention relate essentially to measures for the vibration mounting of the drive unit. In particular, a flat elliptical to oscillating oscillating movement is thus transmitted to the connecting part end of the drive unit, so that the sliding guide of a tool mounted to move back and forth on the device housing is subjected to less stress. This also prevents canting in the sliding guide and extends its service life.

Auch sind erfindungsgemäße Maßnahmen vorgesehen, die eine zusätzliche, gegebenenfalls eine andere Antriebsbewegung mittels einer schwingend angetriebenen Masse ermöglichen.Measures according to the invention are also provided which enable an additional, possibly a different drive movement by means of an oscillatingly driven mass.

Die Erfindung wird anhand eines motorischen Rasierapparatus näher erläutert, wobri der Übersicht wegen zwei unterschiedliche Ausführungsbeispiel zeichnerisch dargestellt sind. Es zeigen: Fig. 1 im Längsschnitt einen Rasierapparat, dessen Schnittelement erfindungsgemäß von einem durch ein Schwunggewicht schwingend bewegten Motor oszillierend angetriebene ist, Fig. 2 in größerem Maßstab die Antriebsverbindung zwischen Verbindungsteil und Schnittelement von Fig. 1, Fig. 3 im Längsschnitt einen weiteren Rasierapparat, dessen Schnittelement erfindungsgemäß von einem durch einen Exzenter schwingend bewegten Motor oszillierend angetrieben ist, Fig. 4 eine Draufsicht zu Fig. 3 mit abgenommener Gehäusehälfte, Fig. 5 einen Querschnitt nach der Linie I-I in Fig. 3 und Fig. 6 eine auf einen Rahmen montierte Antriebseinheit gemäß Fig. 1 und Fig. 3 in Ansicht.The invention is explained in more detail with the aid of a motorized shaving apparatus, with two different exemplary embodiments being shown in the drawing for clarity. 1 shows a shaving apparatus in longitudinal section, the cutting element according to the invention of which is oscillatingly driven by a motor oscillating through a swinging weight, FIG. 2 shows the drive connection between the connecting part and the cutting element from FIG. 1 on a larger scale, FIG. 3 shows a further longitudinal section Shaving apparatus, the cutting element of which according to the invention is oscillatingly driven by a motor oscillating through an eccentric, Fig. 4 is a plan view of Fig. 3 with the housing half removed, Fig. 5 is a cross section along the line II in Fig. 3 and Fig. 6 is a on a frame-mounted drive unit according to FIG. 1 and FIG. 3 in view.

In Fig. 1 und 3 ist der Schwingungsantrieb für einen Rasierapparat dargestellt, welcher Antrieb mittels der Masse eines durch ein Schwunggewicht 3 und/oder einen Exzenter 22 schwingend bewegten Motors 1 durchgeführt wird, der zumindest mit einem Verbindungsteil 5 eine Antriebseinheit 8 bildet, die im bzw. am Gerätegehäuse 10 schwingbar gehalten ist und ihre Schwingbewegung auf ein als Schnittelement ausgebildetes Werkzeug 14 überträgt.In Fig. 1 and 3, the vibration drive for a shaver is shown, which drive is carried out by means of the mass of a motor 1 vibratingly moved by a swing weight 3 and / or an eccentric 22, which forms at least with a connecting part 5 a drive unit 8, which in the or is held in an oscillatable manner on the device housing 10 and transmits its oscillating movement to a tool 14 designed as a cutting element.

Erfindungsgemäß ist das Schnittelement 14 für sich im Gerätegehäuse 10 in an sich bekannter Weise im wesentlichen oszillierend gelagert und es steht die zumindest aus dem schwingend bewegten Motor 1 und dem Verbindungsteil 5 bestehende Antriebseinheit 8 mit ihrem Verbindungsteilende 5' mit dem Schnittelement 14 in unmittelbar Antriebsverbindung. Dabei ist das Verbindungsteil 5 mit dem vom Schwunggewicht 3 bzw. vom Exzenter 22 abgewendete Ende des Motorgehäuses 1' verbunden und in einer vorzugsweise pendelartige Schwingbewegungen der Antriebseinheit 8 zulassenden Halterung 9 im Gerätegehäuse 10 gelagert. Der Motor 1 wirkt dadurch über das vorzugsweise in der Halterung 9 liegende Verbindungsteil 5 hebelartig auf das Schnittelement 14 ein.According to the invention, the cutting element 14 is mounted in an essentially oscillating manner in the device housing 10 in a manner known per se, and the drive unit 8 consisting at least of the oscillatingly moving motor 1 and the connecting part 5 is in direct drive connection with the connecting element end 5 'with the cutting element 14. The connecting part 5 is connected to the end of the motor housing 1 ′ facing away from the flywheel weight 3 or from the eccentric 22 and is mounted in a holder 9 in the device housing 10 which preferably allows pendulum-like oscillating movements of the drive unit 8. As a result, the motor 1 acts on the cutting element 14 in a lever-like manner via the connecting part 5, which is preferably located in the holder 9.

Gemäß Fig. 1 ist das Verbindungsteilende 5' der Antriebseinheit 8 in einer im Schnittelement 14 angeordneten, senkrecht zur Richtung seiner im wesentlichen oszillierenden Bewegung ausgerichteten Schlitzführung 15 bewegbar. Falls die Halterung 9 ähnlich wie das Pendellager in der EU-PA 0 012 129 als Kugelgelenk ausgebildet ist, wird die Antriebseinheit 8 eine taumeiartige Schwingbewegung ausführen. Nachdem das Antriebsteilende 5' in unmittelbarer Antriebsverbindung mit dem eine Schlitzführung 15 aufweisenden und oszillierend am Gerätegehäuse 10 gelagerten Schnittelement 14 steht, wird dieses in Richtung seiner Schwinglagerung oszillierend angetrieben. Um nun die Antriebseinheit 8 in eine vorteilhaftere Umlaufbahn, nämlich in eine elliptisch schwingende Taumelbewegung zu bringen, ist vorgesehen, daß zur Schwinglagerung der Antriebseinheit 8 eine in Richtung der Schlitzführung 15 für das Verbindungsteilende 5' orientierte Schwenkachse 9' als Halterung dient. Die Schwenkachse 9' besteht vorzugsweise aus zwei einander gegenüberliegend angeordneten Gummibolzen, die einerseits mit dem Ansatz 4 des Antriebsteiles 5 verbunden sind und andereseits mit dem aus zwei Teilen 10'u. 10" bestehenden Gerätegehäuse mit den Schrauben 12 befestigt sind. Damit ist die Antriebseinheit 8 in dem in nicht näher dargestellter Weise durch weitere Schrauben zusammengefügten Gehäuse 10 elastisch schwingbar gelagert und wird dadurch eine elliptisch schwingende Taumelbewegung ausführen.1, the connecting part end 5 'of the drive unit 8 is movable in a slot guide 15 arranged in the cutting element 14 and oriented perpendicular to the direction of its essentially oscillating movement. If the holder 9, like the self-aligning bearing in EU-PA 0 012 129, is designed as a ball joint, the drive unit 8 will perform a wobbly swinging movement. After the drive part end 5 'is in direct drive connection with the cutting element 14, which has a slot guide 15 and is mounted in an oscillating manner on the device housing 10, it is driven in an oscillating manner in the direction of its oscillating mounting. In order to bring the drive unit 8 into a more advantageous orbit, namely into an elliptically oscillating wobble movement, it is provided that a pivot axis 9 'oriented in the direction of the slot guide 15 for the connecting part end 5' serves as a holder for the oscillatory mounting of the drive unit 8. The pivot axis 9 'preferably consists of two rubber bolts arranged opposite one another, which are connected on the one hand to the shoulder 4 of the drive part 5 and on the other hand to that of two parts 10'u. 10 "existing device housing are fastened with the screws 12. Thus, the drive unit 8 is mounted in the housing 10, which is not shown in more detail by additional screws, so that it can be swung elastically and will thus perform an elliptically oscillating wobble movement.

Die in der Halterung 9' gelagerte Antriebseinheit 8 ist an dem dem Schwunggewicht 3 zugewendeten Ende gegenüber dem Gerätegehäuse 10 zusätzlich elastisch abgestützt. Die Abstützung besteht aus zwei einander gegenüberliegenden, zwischen dem Gerätegehäuse 10 und einer mittelbar auf der Motorwelle 2 laufenden Buchse 20 angeordneten Schraubenfedern 21, die richtungsgleich mit der Schlitzführung 15 orientiert liegen. Die Buchse 20 ist dabei an einem Ansatz des auf der Motorwelle 2 befestigten Schwunggewichtes 3 laufend angeordnet. Dadurch wird das Antriebsteilende 5' der Antriebseinheit 8 eine flach elliptische Umlaufbahn einnehmen.The drive unit 8 mounted in the holder 9 'is additionally elastically supported at the end facing the swing weight 3 with respect to the device housing 10. The support consists of two opposite coil springs 21 which are arranged between the device housing 10 and a bush 20 running indirectly on the motor shaft 2 and which are oriented in the same direction as the slot guide 15. The bushing 20 is continuously arranged on a shoulder of the flywheel 3 attached to the motor shaft 2. As a result, the drive part end 5 'of the drive unit 8 will assume a flat elliptical orbit.

Der im wesentlichen aus dem Schnittelement 14, dem Scherblatthalter 18 und dem Scherblatt 17 bestehende sogenannte Scherkopf 19 kann im übrigen gleich wie bei an sich bekannten motorisch angetriebenen Rasierapparaten ausgebildet sein. Auch in dieser Figur nicht näher dargestellte elektrische Einrichtungen, wie z. B. ein Schalter, können wie bekannte am Gerätegehäuse 10 angeordnet sein.The so-called shaving head 19 consisting essentially of the cutting element 14, the shaving blade holder 18 and the shaving blade 17 can, moreover, be designed in the same way as in the case of known motor-driven shavers. Also not shown in this figure electrical devices such. B. a switch can be arranged as known on the device housing 10.

Die Fig. 2 zeigt das Schnittelement 14 in einer unmittelbaren Antriebsverbindung mit dem Verbindungsteilende 5' der Antriebseinheit 8. Um eine Verkantung zu verhindern, ist die Schlitzführung 15 abgerundet. Das Schnittelement 14 ist in Achsrichtung der Antriebseinheit 8 beweglich und wird, wie Fig. 1 zeigt, durch die Druckfeder 16 gegen die Innenseite des Scherblattes 17 gedrückt. Das Schnittelement 14 ist dabei in einem als Werkzeugträger wirkenden Trägerelement 14' eingesetzt.2 shows the cutting element 14 in a direct drive connection with the connecting part end 5 'of the drive unit 8. In order to prevent tilting, the slot guide 15 is rounded. The cutting element 14 is movable in the axial direction of the drive unit 8 and, as shown in FIG. 1, is pressed by the compression spring 16 against the inside of the shear blade 17. The cutting element 14 is inserted in a carrier element 14 'which acts as a tool carrier.

Gemäß Fig. 3 u. 4 ist zum Schwingabtrieb der Antriebseinheit 8 ein an der Motorwelle 2 angeordneter Exzenter 22 vorgesehen, der zumindest mittelbar in eine im Gerätegehäuse 10 senkrecht zur oszillierenden Schwinglagerung des Schnittelementes 14 angeordnete Schlitzführung 15' eingreift. Gemäß Fig. 5 ist die Schlitzführung 15' in einem Lagerteil 24 gelegen, welches an beiden Enden mit in Richtung der Schlitzführung 15' angeordneten Achsen 28 endet. Dabei ist das Lagerteil 24 mit den Achsen 28 in Ansätzen 29 der Gehäuseteil 10' bzw. 10" in Schwenkrichtung des Schnittelementes 14 schwenkbar gelagert.3 u. 4, an eccentric 22, which is arranged on the motor shaft 2, is provided for the vibration output of the drive unit 8 and engages at least indirectly in a slot guide 15 'arranged in the device housing 10 perpendicular to the oscillating oscillating bearing of the cutting element 14. 5, the slot guide 15 'is located in a bearing part 24 which ends at both ends with axes 28 arranged in the direction of the slot guide 15'. The bearing part 24 with the axles 28 is pivotably mounted in the projections 29 of the housing part 10 ′ or 10 ″ in the pivoting direction of the cutting element 14.

Unter der Voraussetzung, daß dabei die Antriebseinheit 8 in oben genannter Weise, nämlich mittels eines Kugelgelenkes oder einander gegenüberliegenden Gummibolzen 9' o. dgl. schwingbar bzw. schwenkbar im Gerätegehäuse 10 gelagert und ggf. zusätzlich elastisch abgestützt ist, wird diese ebenso eine kreisförmige oder elliptische Taumelbewegung ausführen.Provided that the drive unit 8 in the above-mentioned manner, namely by means of a ball joint or mutually opposed rubber bolts 9 'or the like, is pivotally or pivotably mounted in the device housing 10 and, if necessary, is additionally elastically supported, this is also a circular or Carry out an elliptical wobble.

Gemäß Fig. 3 u. 4 ist zur Schwinglagerung der Antriebseinheit 8 in Richtung der Schlitzführung 15' für den Exzenter 22 orienterte Schwenkachse 9" vorgesehen, welche im wesentlichen starr ausgebildet ist. Die Antriebseinheit 8 kann dadurch nur mehr eine Schwenkbewegung ausführen, wobei dem Antriebsteilende 5' eine hin-und herschwingende Pendelbewegung übermittelt wird. Das Schnittelement 14, welches in der selben Weise wie Fig. 1 zeigt, im Gerätegehäuse 10 angeordnet sein kann, benötigt dadurch für eine hin- und herschwingende Bewegung keine Schlitzführung mehr. Die Schwenkachse 9" ist im Lagerteil 25 eingepreßt, welches über die elastische Unterlage 26 am Gehäuseteil 10" befestigt ist. Es sind auch an sich bekannte Mittel, nämlich zwei einander in Schwingrichtung des Schnittelementes 14 an der Antriebseinheit 8 eingreifende elastische Elemente, wie z. B. Schraubenfedern 27, vorgesehen, durch welche die Grenzen bzw. die Amplitude der Schwingbewegung der Antriebseinheit 8 einstellbar sind. Dieselben sind zwischen dem Lagerteil 25 und dem Verbindungsteil 5 angeordnet.3 u. 4 is provided for the swing mounting of the drive unit 8 in the direction of the slot guide 15 'for the eccentric 22 oriented pivot axis 9 ", which is essentially rigid. The drive unit 8 can therefore only perform a pivoting movement, the drive part end 5' moving back and forth The cutting element 14, which can be arranged in the device housing 10 in the same way as shown in FIG. 1, therefore no longer requires a slot guide for a back and forth movement Pressed-in bearing part 25, which is fastened to the housing part 10 ″ via the elastic base 26. There are also known means, namely two elastic elements, such as helical springs 27, which engage on the drive unit 8 in the direction of oscillation of the cutting element 14 , by means of which the limits or the amplitude of the oscillating movement of the drive unit 8 can be set, which are arranged between the bearing part 25 and the connecting part 5.

Gemäß Fig. 1 bis 4 weist das Verbindungsteilende 5' der Antriebseinheit 8 einen an sich bekannter Mitnehmer 37 für eine Haarschneideansatzteil eines Rasierapparatus auf. Es können aber am Verbindungsteil 5 auch andere Antriebselemente, wie z. B. Gestänge o. dgl., für die Ubertragung der Antriebsbewegung auf eine Antriebsachse oder Antriebswelle angeschlossen sein. Die Übertragung kann auch auf eine fortschreitend wirkende Antriebsbewegung hinzielen.1 to 4, the connecting part end 5 'of the drive unit 8 has a driver 37 known per se for a hair cutting attachment part of a shaving apparatus. But it can also other drive elements such as. B. linkage or the like. For the transmission of the drive movement to a drive axle or drive shaft. The transmission can also aim for a progressively acting drive movement.

Gemäß Fig. 4 ist der Motor 1 der Antriebseinheit 8 von zwei aufladbaren Batterien 30 angetrieben, welche über die Gerätebuchse 31 von einem nicht dargestellten Ladegerät aufgeladen werden können. Der Motor 1 wird durch den Ein- und Ausschalter 32 betätigt.4, the motor 1 of the drive unit 8 is driven by two rechargeable batteries 30, which can be charged via the device socket 31 by a charger, not shown. The motor 1 is operated by the on and off switch 32.

Gemäß Fig. 6 ist die Antriebseinheit 8 auf einen eine elastische Unterlage 36 aufweisenden Rahmen 34 montiert. Die Antriebseinheit 8 kann dadurch auch unabhängig vom Gehäuse 10 zusammengesetzt und erst dann erforderlichenfalls im Gehäuse 10 eingesetzt werden.6, the drive unit 8 is mounted on a frame 34 having an elastic base 36. The drive unit 8 can thereby also be assembled independently of the housing 10 and only then used in the housing 10 if necessary.

Die erfindungsgemäßen Vorteile können auch durch eine andere als oben dargestellte Schwinglagerung der Antriebseinheit 8 erzielt werden. Insbesondere kann anstelle der beispielsweise dargestellten Achslagerung 9 die Antriebseinheit 8 auch in einem Kugelgelenk schwingbar oder shwenkbar gelagert sein. Auch kann die Antriebseiheit 8 wie in der EU-PA 0 012 129 dargestellt, im Gehäuse 10 schwingbar gelagert sein. Die Halterung 9 für die Schwingeinheit 8 kann auch zwischen dem Gehäuse 10 und dem Motorgehäuseende 1' angeordnet sein und z. B. aus einem Kardangelenk bestehen. Auch können Schwunggewicht 3 und/oder Exzenter 22 auf einem am Motor 1 mitschwingbar, durch die Motorwelle 2 angetriebenen Vorgelegerad angeordnet sein. Das Werkzeug oder ein dieses aufnehmende Werkzeugträger kann anstelle einer Schlittenführung auch mittels Schwingbolzen o.dgl. am bzw. im Gerätegehäuse schwingbar gelagert sein, sodaß eine parallel zu einer Ebene gerichtete Antriebsbewegung auch kreisförmig übertragen werden kann.The advantages according to the invention can also be achieved by a vibration mounting of the drive unit 8 other than that shown above. In particular, instead of the axle bearing 9 shown as an example, the drive unit 8 can also be mounted so that it can be pivoted or pivoted in a ball joint. The drive unit 8, as shown in EU-PA 0 012 129, can also be mounted such that it can vibrate in the housing 10. The bracket 9 for the vibration unit 8 can also be arranged between the housing 10 and the motor housing end 1 'and z. B. consist of a universal joint. Flywheel weight 3 and / or eccentric 22 can also be arranged on a countershaft that can be oscillated on motor 1 and is driven by motor shaft 2. The tool or a tool holder receiving this can instead of a slide guide or the like by means of rocker bolts. be mounted on or in the device housing so that it can vibrate, so that a drive movement directed parallel to a plane can also be transmitted in a circular manner.

Die Erfindung beziegt sich keineswegs nur auf den beispielsweise dargestellten Rasierapparat-Antrieb. So können u. a. auch Geräte zur Oberflächenbehandlung oder -bearbeitung o. dgl. erfindungsgemäß angetrieben sein.The invention by no means relates only to the shaver drive shown as an example. So u. a. also devices for surface treatment or processing or the like can be driven according to the invention.
