Eine Elektrowerkzeugmaschine mit einem solchen elastischen Element zeigt die Druckschrift WO 2008/000543 A1 .For power tool machines, in particular for drill or chipping hammer, it is known to damp the vibrations in the handle by an elastic element between the handle and the tool housing of the power tool. Such handles are also referred to as anti-vibration handles. By the elastic element of the handle is movable relative to the tool housing in the horizontal and / or vertical direction. A power tool with such an elastic element shows the document WO 2008/000543 A1 ,

Die Druckschrift DE 10 2008 041 511 A1 zeigt eine Handwerkzeugmaschine, die einen elektrischen Schalter sowie eine am elektrischen Schalter angeordnete mechanische Stellvorrichtung, die hier als Schaltwippe ausgebildet ist, umfasst. Der elektrische Schalter ist mit der Schaltwippe betätigbar. Die Schaltwippe ist mittels einer Arretiervorrichtung in einem Betriebszustand der Maschine arretierbar. In Bohrhämmern ist die Schaltwippe zur Steigerung des Anwenderkomforts beispielsweise häufig im "Meißelbetrieb" arretierbar, damit der Bediener den Schalter in diesem Betriebsmodus nicht ständig gedrückt halten muss. Allerdings darf die Schaltwippe im "Bohr-" oder "Bohrhammerbetrieb" nicht arretierbar sein, damit die Elektrowerkzeugmaschine bei einem Verkanten des Bohrers schnellstmöglich vom Bediener ausschaltbar ist und sich nicht unkontrolliert verdreht, und damit sich der Bediener daher nicht verletzt.The publication DE 10 2008 041 511 A1 shows a hand tool, which comprises an electrical switch and a arranged on the electrical switch mechanical actuator, which is designed here as a rocker switch. The electrical switch can be actuated with the rocker switch. The switching rocker can be locked by means of a locking device in an operating state of the machine. In rotary hammers, for example, the rocker switch is often used to increase user comfort "Chisel" lockable so that the operator does not have to keep the switch pressed in this operating mode constantly. However, the rocker switch must not be able to be locked in "drilling" or "hammer drill operation" so that the power tool can be switched off as quickly as possible by the operator when tilting the drill and does not twist uncontrollably, so that the operator is not injured.

Allerdings ist die Arretierfunktion bei Antivibrationshandgriffen nur sehr schwer realisierbar, da ein Betriebsmodusschalter herkömmlich am Werkzeuggehäuse angeordnet ist und zwischen dem Handgriffgehäuse und dem Werkzeuggehäuse eine Relativbewegung von mehreren Millimetern auftreten kann. Außerdem erfordert eine solche Arretierung eine mechanische Umlenkung zwischen dem Betriebsmodusschalter und der Arretierung der Schaltwippe. Und weiterhin erfordert ein solcher Ein- und Ausschalter erheblichen Bauraum, der umso größer ist, je leistungsstärker die Elektrowerkzeugmaschine ist.However, the locking function with anti-vibration handles is very difficult to achieve, since an operating mode switch is conventionally arranged on the tool housing and between the handle housing and the tool housing a relative movement of several millimeters can occur. In addition, such a lock requires a mechanical deflection between the operating mode switch and the locking of the rocker switch. And further, such an on-off switch requires considerable space, which is the greater, the more powerful the power tool is.

Die Druckschrift DE 100 34 768 A1 offenbart beispielsweise einen leistungsstarken Bohrhammer, bei dem der Betriebsmodusschalter starr an eine Arretiervorrichtung für eine Schaltklinke gekoppelt ist. Diese starre Ankopplung ermöglicht jedoch in Bezug auf die Vibrationen eines Werkzeuggehäuses der Elektrowerkzeugmaschine keine vollständige Entkopplung des Handgriffgehäuses vom Werkzeuggehäuse. Außerdem benötigt der für die Ankopplung der Arretiervorrichtung an den Betriebsmodusschalter erforderliche Hebelmechanismus erheblichen Bauraum. Und zudem ist die Arretiervorrichtung auch nicht staubgeschützt.The publication DE 100 34 768 A1 discloses, for example, a powerful rotary hammer in which the operating mode switch is rigidly coupled to a locking device for a pawl. However, this rigid coupling does not allow complete decoupling of the handle housing from the tool housing with respect to the vibrations of a tool housing of the power tool. In addition, required for the coupling of the locking device to the operating mode switch lever mechanism requires considerable space. And also, the locking device is not dust-proof.

Die Druckschrift DE 36 22 003 A1 offenbart einen elektrischen Schaltmechanismus, welches als Tastschalter, Taster, Wippschalter oder Wipptaster verwendbar ist.The publication DE 36 22 003 A1 discloses an electrical switching mechanism which can be used as a push button, push button, rocker switch or rocker switch.

Aufgabe der vorliegenden Erfindung ist es, eine insbesondere leistungsstarke Elektrowerkzeugmaschine zu schaffen, die eine größtmögliche Sicherheit für den Nutzer bei der Handhabung gewährleistet, und die in zumindest einem Betriebszustand der Maschine eingeschaltet ist, ohne ein Betätigungsmittel für den Antrieb der Elektrowerkzeugmaschine dauerhaft betätigen zu müssen, wobei der Handgriff als vom Werkzeuggehäuse vollständig entkoppelter Antivibrationshandgriff ausbildbar ist, und wobei der Handgriff sehr kompakt und stabil aufgebaut ist. Eine weitere Aufgabe der Erfindung ist es, den Staubschutz für die Antivibrationsvorrichtung zu verbessern.Object of the present invention is to provide a particularly powerful power tool that ensures maximum safety for the user in handling, and in at least one operating state of the machine is turned on, without having to actuate an actuating means for driving the power tool permanently, wherein the handle can be formed as completely decoupled from the tool housing anti-vibration handle, and wherein the handle is constructed very compact and stable. Another object of the invention is to improve the dust cover for the anti-vibration device.

Die Aufgabe wird gelöst mit einem elektrischen Schalter gemäß dem Patentanspruch 1 sowie einer Elektrowerkzeugmaschine gemäß dem Patentanspruch 11. weitere vorteilhafte Ausführungsformen sind in den Unteransprüchen offenbart.The object is achieved with an electrical switch according to the patent claim 1 and a power tool according to the claim 11 further advantageous embodiments are disclosed in the dependent claims.

Der elektrische Schalter für eine Elektrowerkzeugmaschine, insbesondere einen Bohr- oder Meißelhammer, umfasst eine erste Schaltvorrichtung sowie eine zweite Schaltvorrichtung, wobei die erste Schaltvorrichtung durch Verstellen eines ersten mechanischen Signalmittels von einem ersten Schaltzustand in einen zweiten Schaltzustand reversibel verstellbar ist, wobei die zweite Schaltvorrichtung durch Verstellen eines zweiten elektrischen oder mechanischen Signalmittels von einem dritten Schaltzustand, in dem der elektrische Schalter als Taster wirkt, in einen vierten Schaltzustand, in dem er als Wippschalter wirkt, reversibel verstellbar ist.The electrical switch for a power tool, in particular a drill or chisel, comprises a first switching device and a second switching device, wherein the first switching device is reversibly adjustable by adjusting a first mechanical signal means from a first switching state to a second switching state, wherein the second switching device Adjusting a second electrical or mechanical signaling means of a third switching state in which the electrical switch acts as a button, in a fourth switching state in which it acts as a rocker switch, is reversibly adjustable.

Bei einem Taster im Sinne der Erfindung kehrt der elektrische Schalter selbsttätig vom zweiten Schaltzustand in den ersten Schaltzustand zurück. Dabei ist es bevorzugt, dass der elektrische Schalter gegen die Rückstellkraft eines ersten Kraftmittels von dem ersten Schaltzustand in den zweiten Schaltzustand verstellt wird, so dass er mittels der Rückstellkraft des ersten Kraftmittels selbsttätig zurückgestellt wird.When a button according to the invention, the electrical switch automatically returns from the second switching state in the first switching state. It is preferred that the electrical switch is adjusted against the restoring force of a first force means from the first switching state to the second switching state, so that it is automatically reset by means of the restoring force of the first force means.

Bei einem Wippschalter im Sinne der Erfindung kehrt der elektrische Schalter nicht vom zweiten Schaltzustand in den ersten Schaltzustand selbsttätig zurück, sondern verharrt im zweiten Schaltzustand.In a rocker switch according to the invention, the electrical switch does not return automatically from the second switching state to the first switching state, but remains in the second switching state.

Der erfindungsgemäße Schalter ist im vierten Schaltzustand, in dem er als Wippschalter wirkt, daher bevorzugt entweder arretiert oder zumindest arretierbar. Im Rahmen der Fig. 1 - 6 wird der vierte Schaltzustand daher als Arretierzustand bezeichnet.The switch according to the invention is therefore preferably either locked or at least in the fourth switching state in which it acts as a rocker switch lockable. As part of the Fig. 1 - 6 Therefore, the fourth switching state is referred to as a locking state.

Der elektrische Schalter ist daher selbst arretierbar oder arretiert. Ein erfindungsgemäßer elektrischer Schalter ist im Vergleich zu einer herkömmlichen Vorrichtung, bei der eine mechanische Stellvorrichtung zum Betätigen eines herkömmlichen elektrischen Schalters mittels einer separaten Arretiervorrichtung arretierbar ist, erheblich kompakter baubar und ermöglicht somit eine erheblich flexiblere Platzierung in eine Elektrowerkzeug maschine, sowie aufgrund des nicht benötigen Bauraums eine kompaktere Gestaltung der Elektrowerkzeugmaschine.The electrical switch is therefore self-lockable or locked. An inventive electrical switch is compared to a conventional device in which a mechanical actuator for actuating a conventional electrical switch can be locked by means of a separate locking device, considerably compact buildable and thus allows a much more flexible placement in a power tool machine, as well as due to the space not required a more compact design of the power tool.

Es ist bevorzugt, dass der zweite Schaltzustand ein Einschaltzustand ist, in dem der elektrische Schalter einen Stromkreis, insbesondere einen Motorstromkreis zum Antrieb der Elektrowerkzeugmaschine, schließt, und dass der erste Schaltzustand ein Ausschaltzustand ist, in dem der Stromkreis geöffnet ist. Je nach Anwendungsfall ist aber auch eine Ausführungsform bevorzugt, bei der der erste Schaltzustand der Einschaltzustand und der zweite Schaltzustand der Ausschaltzustand ist, so dass der elektrische Schalter selbsttätig vom Ausschaltzustand in den Einschaltzustand zurück kehrt.It is preferable that the second switching state is a turn-on state in which the electric switch closes a circuit, in particular a motor circuit for driving the electric machine tool, and that the first switching state is a turn-off state in which the circuit is opened. Depending on the application, however, an embodiment is also preferred in which the first switching state is the switch-on state and the second switch state is the switch-off state, so that the electrical switch automatically returns from the switch-off state to the switch-on state.

Es ist weiterhin bevorzugt, dass der elektrische Schalter gegen die Rückstellkraft eines zweiten Kraftmittels vom dritten Schaltzustand in den Arretierzustand verstellt wird, so dass er mittels der Rückstellkraft des zweiten Kraftmittels vom Arretierzustand in den dritten Schaltzustand zurück gestellt wird. Je nach Anwendungsfall ist aber auch eine Ausführungsform bevorzugt, bei der der elektrische Schalter gegen die Rückstellkraft des zweiten Kraftmittels vom Arretierzustand in den dritten Schaltzustand verstellt wird, so dass er mittels der Rückstellkraft des zweiten Kraftmittels vom dritten Schaltzustand in den Arretierzustand zurück gestellt wird.It is further preferred that the electrical switch is adjusted against the restoring force of a second force means from the third switching state to the locking state, so that it is set back by means of the restoring force of the second power means from the locking state to the third switching state. Depending on the application, however, an embodiment is preferred in which the electrical switch is adjusted against the restoring force of the second force means from the locking state to the third switching state, so that it is set by the restoring force of the second power from the third switching state back to the locked state.

In einer besonders bevorzugten Ausführungsform wird der elektrische Schalter gegen die Rückstellkraft des zweiten Kraftmittels vom dritten Schaltzustand in den Arretierzustand verstellt, wobei er gegen die Kraft des ersten Kraftmittels vom Ausschaltzustand in den Einschaltzustand verstellt wird. In dieser bevorzugten Ausführungsform ist der dritte Schaltzustand ein Grundzustand des elektrischen Schalters, und der elektrische Schalter beispielsweise als Motorschalter zum Antrieb der Elektrowerkzeugmaschine verwendbar.In a particularly preferred embodiment, the electric switch is moved against the restoring force of the second force means from the third switching state to the locking state, wherein it is adjusted against the force of the first power means from the off state to the on state. In this preferred embodiment, the third switching state is a ground state of the electric switch, and the electric switch can be used, for example, as a motor switch for driving the electric machine tool.

Bevorzugt umfasst die erste Schaltvorrichtung einen elektrischen Kontakt sowie elektrische Anschlüsse zum Schließen des Stromkreises. Der elektrische Kontakt ist bevorzugt vorgesehen, um die elektrischen Anschlüsse im Ausschaltzustand nicht zu verbinden, so dass der Stromkreis geöffnet ist, und um die elektrischen Anschlüsse im Einschaltzustand zu verbinden, so dass der Stromkreis geschlossen ist.Preferably, the first switching device comprises an electrical contact and electrical connections for closing the circuit. The electrical contact is preferably provided in order not to connect the electrical connections in the off state, so that the circuit is opened is, and to connect the electrical connections in the on state, so that the circuit is closed.

Es ist weiterhin bevorzugt, dass der elektrische Schalter ein Gehäuse umfasst. Dabei ist es besonders bevorzugt, dass lediglich das erste und zweite Signalmittel sowie die elektrischen Anschlüsse teilweise außerhalb des Gehäuses angeordnet sind, damit sie von außen zugänglich sind. Dadurch ist der Schalter gegen äußere Einflüsse wie beispielsweise das Eindringen von Staub und Feuchtigkeit geschützt. Vorteilhafter Weise ist der Schalter dieser Ausführungsform als ein einziges modulares Bauteil vorfertigbar, so dass er kostengünstig lagerbar ist und für Elektrowerkzeugmaschinen verschiedenen Typs nutzbar ist.It is further preferred that the electrical switch comprises a housing. It is particularly preferred that only the first and second signaling means and the electrical connections are partially disposed outside of the housing so that they are accessible from the outside. As a result, the switch is protected against external influences such as the ingress of dust and moisture. Advantageously, the switch of this embodiment is vorfertigbar as a single modular component, so that it is inexpensive to store and can be used for electric machine tools of various types.

In einer bevorzugten Ausführungsform umfasst die erste Schaltvorrichtung weiterhin ein erstes Stellmittel, welches mit dem ersten Signalmittel zusammenwirkt, wobei der elektrische Kontakt mittels des ersten Stellmittels verstellbar ist. Beim Verstellen des ersten Signalmittels wird das erste Stellmittel verstellt, so dass der elektrische Kontakt vom Ausschaltzustand in den Einschaltzustand verstellt oder zurück gestellt wird. Das erste Stellmittel ist bevorzugt als ein Schiebemittel oder als ein Drehmittel vorgesehen.In a preferred embodiment, the first switching device further comprises a first adjusting means, which cooperates with the first signal means, wherein the electrical contact is adjustable by means of the first adjusting means. When adjusting the first signal means, the first adjusting means is adjusted, so that the electrical contact is moved from the off state to the on state or reset. The first adjusting means is preferably provided as a pushing means or as a rotating means.

In einer weiteren bevorzugten Ausführungsform umfasst die zweite Schaltvorrichtung ein zweites Stellmittel, welches mit dem zweiten Signalmittel zusammenwirkt, wobei das erste Signalmittel und/oder das erste Stellmittel mittels des zweiten Stellmittels im Arretierzustand arretierbar oder arretiert sind. Beim Verstellen des zweiten Signalmittels wird daher das zweite Stellmittel bevorzugt so verstellt, dass es die Bewegung des ersten Signalmittels und/oder des ersten Stellmittels verhindert. Das zweite Stellmittel ist ebenfalls bevorzugt als ein Schiebemittel oder ein Drehmittel vorgesehen.In a further preferred embodiment, the second switching device comprises a second actuating means, which cooperates with the second signal means, wherein the first signal means and / or the first actuating means by means of the second actuating means in the locking state can be locked or locked. When adjusting the second signal means therefore the second adjusting means is preferably adjusted so that it prevents the movement of the first signal means and / or the first actuating means. The second adjusting means is also preferably provided as a pushing means or a rotating means.

In dieser bevorzugten Ausführungsform sind das erste Signalmittel und/oder das erste Stellmittel durch Verstellen des zweiten Stellmittels im Ausschaltzustand arretierbar und im Einschaltzustand arretiert. Weiterhin sind in dieser bevorzugten Ausführungsform das erste Signalmittel und/oder das erste Stellmittel im Grundzustand nicht mittels des zweiten Stellmittels arretierbar oder arretiert. Der elektrische Schalter verharrt in dieser Ausführungsform daher nur im Arretierzustand im Einschaltzustand. In jedem anderen Zustand befindet er sich entweder im Ausschaltzustand oder er kehrt selbsttätig in den Ausschaltzustand zurück. Ein Verharren im Einschaltzustand muss daher vom Bediener gezielt am Schalter eingestellt werden. Diese Ausführungsform gewährleistet eine größtmögliche Sicherheit gegen ein ungewolltes Einschalten des Stromkreises.In this preferred embodiment, the first signal means and / or the first actuating means are lockable by adjusting the second actuating means in the off state and locked in the on state. Furthermore, in this preferred embodiment, the first signaling means and / or the first adjusting means in the ground state can not be locked or locked by means of the second actuating means. The electrical switch remains in this embodiment, therefore, only in the locked state in the on state. In any other state it is either in the off state or automatically returns to the off state. A persistence in the on state must therefore be set by the operator targeted at the switch. This embodiment ensures the greatest possible security against accidental switching on of the circuit.

Das erste Signalmittel ist bevorzugt mit einem ersten Betätigungsmittel, und das zweite Signalmittel ebenfalls bevorzugt mit einem zweiten Betätigungsmittel betätigbar. Das erste sowie zweite Signalmittel stellen daher die Schnittstelle dar, über die der elektrische Schalter betätigbar und in seine verschiedenen Schaltzustände umschaltbar ist.The first signal means is preferably operable with a first actuating means, and the second signal means also preferably with a second actuating means operable. The first and second signaling means therefore represent the interface through which the electrical switch can be actuated and switched to its various switching states.

In einer bevorzugten Ausführungsform sind das erste Signalmittel und/oder das erste Stellmittel und/oder das erste Betätigungsmittel mechanisch vorgesehen. In dieser Ausführungsform ist das erste Signalmittel bevorzugt mittels des ersten Betätigungsmittels betätigbar, insbesondere verdreh- oder verschiebbar, wobei das erste Stellmittel mittels dem ersten Signalmittel von der Ausschaltposition in die Einschaltposition oder zurück verstellbar ist, insbesondere verdreh- oder verschiebbar. Es ist besonders bevorzugt, dass das erste Signalmittel als Winkelhebel ausgebildet ist, wobei das erste Stellmittel bevorzugt als Schiebemittel ausgebildet ist, und wobei das erste Betätigungsmittel bevorzugt als Schaltwippe ausgebildet ist. Dann ist der Winkelhebel vorzugsweise mittels der Schaltwippe betätigbar, insbesondere verdrehbar, wobei das Schiebemittel mittels des Winkelhebels von der Ausschaltposition in die Einschaltposition oder zurück verschiebbar ist.In a preferred embodiment, the first signal means and / or the first actuating means and / or the first actuating means are mechanically provided. In this embodiment, the first signal means preferably by means of the first actuating means operable, in particular rotatable or displaceable, wherein the first actuating means by means of the first signal means from the off position to the on or back position is adjustable, in particular twisted or displaceable. It is particularly preferred that the first signal means is designed as an angle lever, wherein the first adjusting means is preferably designed as a sliding means, and wherein the first actuating means is preferably designed as a rocker switch. Then, the angle lever is preferably actuated by means of the rocker switch, in particular rotatable, wherein the sliding means by means of the angle lever from the off position to the on position or back is displaceable.

Die Schaltwippe ist bevorzugt drehbar an dem Schaltergehäuse des elektrischen Schalters gelagert. In dieser Ausführungsform weist die Schaltwippe bevorzugt einen ersten Schaltwippenteil sowie einen zweiten Schaltwippenteil auf, wobei der elektrische Schalter durch Betätigen des ersten Schaltwippenteils in den Einschaltzustand, und durch Betätigen des zweiten Schaltwippenteils in den Ausschaltzustand verstellbar ist.The switching rocker is preferably rotatably mounted on the switch housing of the electrical switch. In this embodiment, the rocker preferably on a first rocker switch part and a second rocker switch part, wherein the electrical switch is adjustable by operating the first rocker switch part in the on state, and by operating the second rocker switch part in the off state.

In einer weiteren bevorzugten Ausführungsform sind das zweite Signalmittel und/oder das zweite Stellmittel und/oder das zweite Betätigungsmittel mechanisch vorgesehen. In dieser Ausführungsform ist das zweite Signalmittel bevorzugt mittels des zweiten Betätigungsmittels betätigbar, insbesondere verdreh- oder verschiebbar, wobei das zweite Stellmittel mittels dem zweiten Signalmittel von der Ausschaltposition in die Einschaltposition oder zurück verstellbar, insbesondere verdreh- oder verschiebbar, ist. Es ist besonders bevorzugt, dass das zweite Signalmittel als Schalthebel ausgebildet ist, wobei das zweite Stellmittel bevorzugt als Arretierklinke ausgebildet ist, und wobei das zweite Betätigungsmittel bevorzugt als Schaltverbindung, insbesondere als ein Zugmittel oder als ein Bowdenzug, ausgebildet ist. Dann ist der Schalthebel vorzugsweise mittels der Schaltverbindung betätigbar, insbesondere verdrehbar, wobei die Arretierklinke mittels des Winkelhebels von der Grundposition in die Arretierposition oder zurück verdrehbar ist.In a further preferred embodiment, the second signal means and / or the second actuating means and / or the second actuating means are provided mechanically. In this embodiment, the second signal means is preferably actuated by means of the second actuating means, in particular rotatable or displaceable, wherein the second actuating means by means of the second signal means from the off position to the on position or back adjustable, in particular rotatable or displaceable is. It is particularly preferred that the second signal means is designed as a shift lever, wherein the second actuating means is preferably designed as a locking pawl, and wherein the second actuating means is preferably designed as a switching connection, in particular as a traction means or as a Bowden cable. Then, the shift lever is preferably actuated by means of the switch connection, in particular rotatable, wherein the locking pawl by means of the angle lever from the basic position to the locking position or back is rotatable.

Die Arretierklinke ist bevorzugt am Schalthebel gelagert, und wirkt im Arretierzustand mit dem Schiebemittel zusammen. Dafür weist das Schiebemittel ebenfalls bevorzugt ein Blockiermittel auf, welches im Arretierzustand an der Arretierklinke anliegt, so dass das Schiebemittel im Einschaltzustand arretiert und nicht mehr verschiebbar ist. Dadurch ist ein selbsttätiges Zurückstellen des Schiebemittels, und somit auch des Winkelhebels, mittels der Rückstellkraft des ersten Kraftmittels nicht möglich.The locking pawl is preferably mounted on the shift lever, and cooperates with the sliding means in the locked state. For this purpose, the sliding means also preferably has a blocking means, which rests against the locking pawl in the locking state, so that the sliding means is locked in the switched-on state and can no longer be displaced. As a result, an automatic reset of the sliding means, and thus also of the angle lever, by means of the restoring force of the first power means is not possible.

Es ist ebenfalls bevorzugt, dass das zweite Signalmittel und/oder das zweite Stellmittel und/oder das zweite Betätigungsmittel elektrisch, elektronisch oder elektromagnetisch vorgesehen sind. Dann ist das zweite Signalmittel bevorzugt ein Tippsignal, welches beispielsweise durch nochmaliges Tasten oder ein anderes vom Bediener ausgelöstes Signal, insbesondere eines beispielsweise elektrisch vorgesehenen Betriebsmodusschalters der Elektrowerkzeugmaschine, ausgelöst wird. In dieser Ausführungsform erfolgt das Verstellen des zweiten Stellmittels bevorzugt ebenfalls elektrisch, beispielsweise mithilfe eines Relais.It is also preferred that the second signal means and / or the second actuating means and / or the second actuating means are provided electrically, electronically or electromagnetically. Then, the second signal means is preferably a tip signal, which is triggered, for example, by repeated pressing or another signal triggered by the operator, in particular, for example, an electrically provided operating mode switch of the power tool. In this embodiment, the adjustment of the second actuating means preferably also takes place electrically, for example by means of a relay.

Grundsätzlich ist auch eine Ausführungsform möglich, bei der das erste Signalmittel und/oder das erste Stellmittel und/oder das erste Betätigungsmittel elektrisch vorgesehen sind.In principle, an embodiment is also possible in which the first signal means and / or the first actuating means and / or the first actuating means are provided electrically.

Die Aufgabe wird weiterhin gelöst mit einer Elektrowerkzeugmaschine, insbesondere einem Bohr- oder Meißelhammer, mit einem erfindungsgemäßen elektrischen Schalter.The object is also achieved with a power tool, in particular a drill or chisel, with an electrical switch according to the invention.

Da der erfindungsgemäße elektrische Schalter unabhängig von der Leistungsstärke der Elektrowerkzeugmaschine erheblich kompakter herstellbar ist, steht entweder in der Elektrowerkzeugmaschine mehr Bauraum zur Verfügung, oder diese ist ebenfalls kompakter baubar.Since the electric switch according to the invention, regardless of the power of the electric machine tool is much more compact to produce, more space is available either in the power tool, or this is also compact buildable.

In einer bevorzugten Ausführungsform sind der elektrische Schalter sowie das erste Betätigungsmittel in einem Handgriffgehäuse, insbesondere in einem Antivibrationshandgriffgehäuse, angeordnet, wobei die Elektrowerkzeugmaschine einen Betriebsmodusschalter zum Verstellen des zweiten Betätigungsmittels umfasst, der in einem Werkzeuggehäuse angeordnet ist.In a preferred embodiment, the electrical switch and the first actuating means are arranged in a handle housing, in particular in an anti-vibration handle housing, wherein the power tool comprises an operating mode switch for adjusting the second actuating means, which is arranged in a tool housing.

In dieser Ausführungsform ist das Handgriffgehäuse der Elektrowerkzeugmaschine kompakter herstellbar, so dass die Handhabung der Elektrowerkzeugmaschine einfacher möglich ist.In this embodiment, the handle housing of the power tool is made more compact, so that the handling of the power tool is easier.

Fig. 1 zeigt eine erfindungsgemäße Elektrowerkzeugmaschine 1 mit einem Handgriffgehäuse 3, welches als Antivibrationshandgriffgehäuse ausgebildet ist. Fig. 1 shows a power tool 1 according to the invention with a handle housing 3, which is designed as an anti-vibration handle housing.

Das Handgriffgehäuse 3 stützt sich mittels einer Blattfeder 7 an einem Werkzeuggehäuse 2 ab. Dabei weist die Blattfeder 7 ein erstes Ende (nicht sichtbar) sowie ein zweites Ende 72 auf, wobei sie mit ihrem ersten Ende fest mit dem Werkzeuggehäuse 2 verbunden ist. Am zweiten Ende 72 der Blattfeder 7 stützt sich das Handgriffgehäuse 3 an ihrer Oberseite 73 ab, so dass das Handgriffgehäuse 3 in horizontaler sowie in vertikaler Richtung einfedern kann. Dadurch ist eine Relativbewegung um mehrere Millimeter zwischen dem Werkzeuggehäuse 2 und dem Handgriffgehäuse 3 möglich. Zwischen dem Werkzeuggehäuse 2 und dem Handgriffgehäuse 3 ist ein Faltbalgelement 21 vorgesehen, so dass diese Relativbewegung zwischen dem Werkzeuggehäuse 2 und dem Handgriffgehäuse 3 möglich ist, ohne das Werkzeuggehäuse 2 oder das Handgriffgehäuse 3 zu beschädigen.The handle housing 3 is supported by a leaf spring 7 on a tool housing 2. In this case, the leaf spring 7 has a first end (not visible) and a second end 72, wherein it is connected with its first end fixed to the tool housing 2. At the second end 72 of the leaf spring 7, the handle housing 3 is supported on its upper side 73, so that the handle housing 3 can deflect in a horizontal and in a vertical direction. As a result, a relative movement of several millimeters between the tool housing 2 and the handle housing 3 is possible. Between the tool housing 2 and the handle housing 3, a Faltbalgelement 21 is provided so that this relative movement between the tool housing 2 and the handle housing 3 is possible without damaging the tool housing 2 or the handle housing 3.

In das Handgriffgehäuse 3 ist eine Griffschale 31 lösbar eingelegt, so dass im Handgriffgehäuse 3 angeordnete Maschinenbauteile von außen zugänglich sind.In the handle housing 3, a handle shell 31 is releasably inserted, so that arranged in the handle housing 3 machine components are accessible from the outside.

Die Elektrowerkzeugmaschine 1 dieses Ausführungsbeispiels ist ein Bohrhammer, der mittels eines Betriebsmodusschalters 41 in die Betriebszustände "Bohren", "Hammerbohren" sowie "Meißeln" verstellbar ist. Im Rahmen der Fig. 1 - 6 werden die Begriffe Elektrowerkzeugmaschine 1 und Bohrhammer synonym verwendet. Mittels des Betriebsmodusschalters 41 ist ein Schieber 42 in oder entgegen einer Verschieberichtung 43 verschiebbar, wobei der Schieber 42 gegen die Kraft einer Druckfeder 44, welche sich am Werkzeuggehäuse 2 abstützt, verschoben wird.The electric machine tool 1 of this embodiment is a hammer drill, which is adjustable by means of an operation mode switch 41 in the operating states "drilling", "hammer drilling" and "chiselling". As part of the Fig. 1 - 6 the terms power tool 1 and hammer drill are used synonymously. By means of the operating mode switch 41, a slide 42 is displaceable in or against a displacement direction 43, wherein the slide 42 against the force of a compression spring 44, which is supported on the tool housing 2, is moved.

Am Schieber 42 ist ein erstes Ende 61 eines zweiten Betätigungsmittels 6, welches hier als ein Band ausgeführt ist, festgelegt. Im Rahmen der Fig. 1 - 6 werden die Begriffe zweites Betätigungsmittel 6 und Band synonym verwendet. Im vorliegenden Ausführungsbeispiel ist das erste Ende 61 unter Vorspannung einer Feder 63 eingehängt. Es sind aber auch Ausführungen bevorzugt, in denen das Band 6, beispielsweise durch Verschrauben oder Einclipsen, fest mit dem Schieber 42 verbunden ist. Alternativ ist hier anstelle des Bandes 6 auch das Vorsehen eines Bowdenzugs (nicht gezeigt) möglich.On the slider 42, a first end 61 of a second actuating means 6, which is designed here as a band set. As part of the Fig. 1 - 6 the terms second actuator 6 and band are used synonymously. In the present embodiment, the first end 61 is suspended under bias of a spring 63. However, embodiments are also preferred in which the band 6, for example by screwing or clipping, is firmly connected to the slider 42. Alternatively, the provision of a Bowden cable (not shown) instead of the band 6 is possible here.

Ein zweites Ende 62 des Bandes 6 ist an einem Haken 531 eines zweiten Signalmittels 53 einer zweiten Schaltvorrichtung 5 (s. Fig. 3 - 6 ) eines elektrischen Schalters 800 festgelegt, so dass die Anbindung des Betriebsmodusschalters 41 über das Band 6 direkt an das zweite Signalmittel 53 erfolgt. Das zweite Signalmittel 53 ist hier als Schalthebel ausgeführt. Im Rahmen der Fig. 1 - 6 werden die Begriffe zweites Signalmittel 53 und Schalthebel synonym verwendet. Und zwar ist das zweite Ende 62 hier im Haken 531 eingehängt. Es ist jedoch auch bevorzugt, das zweite Ende 62 mit der zweiten Schaltvorrichtung 5 fest zu verbinden.A second end 62 of the band 6 is connected to a hook 531 of a second signal means 53 of a second switching device 5 (see FIG. Fig. 3 - 6 ) of an electrical switch 800, so that the connection of the operating mode switch 41 via the belt 6 takes place directly on the second signal means 53. The second signal means 53 is designed here as a shift lever. As part of the Fig. 1 - 6 For example, the terms second signaling means 53 and shift levers are used interchangeably. And that is the second end 62 here in Hook 531 hooked. However, it is also preferable to firmly connect the second end 62 with the second switching device 5.

Der Betriebsmodusschalter 41 ist daher über das Band 6 mechanisch mit der zweiten Schaltvorrichtung 5 verbunden.The operation mode switch 41 is therefore mechanically connected to the second switching device 5 via the belt 6.

An dem elektrischen Schalter 800 ist ein erstes Betätigungsmittel 9, das hier als Schaltwippe ausgebildet ist, angeordnet. Im Rahmen der Fig. 1 - 6 werden die Begriffe erstes Betätigungsmittel 9 und Schaltwippe synonym verwendet. Die Schaltwippe 9 ist drehbar am Schaltergehäuse des elektrischen Schalters 800 gelagert. Sie weist einen ersten Schaltwippenteil 91 sowie einen zweiten Schaltwippenteil 92 auf. Durch Betätigen des ersten Schaltwippenteils 91 ist eine erste Schaltvorrichtung 8 des elektrischen Schalters 800 von einem ersten Schaltzustand A in einen zweiten Schaltzustand E verstellbar. Im vorliegenden Ausführungsbeispiel ist der elektrische Schalter 800 als Betriebsschalter der Elektrowerkzeugmaschine 1 vorgesehen. Im Rahmen der Fig. 1 - 6 werden daher die Begriffe elektrischer Schalter 800 und Betriebsschalter synonym verwendet.At the electrical switch 800, a first actuating means 9, which is designed here as a rocker switch, arranged. As part of the Fig. 1 - 6 the terms first actuating means 9 and rocker switch are used synonymously. The switching rocker 9 is rotatably mounted on the switch housing of the electrical switch 800. It has a first rocker switch part 91 and a second rocker switch part 92. By actuating the first rocker switch part 91, a first switching device 8 of the electrical switch 800 is adjustable from a first switching state A to a second switching state E. In the present exemplary embodiment, the electrical switch 800 is provided as the operating switch of the power tool 1. As part of the Fig. 1 - 6 Therefore, the terms electrical switches 800 and operation switches are used synonymously.

Da der elektrische Schalter 800 hier der Betriebsschalter der Elektrowerkzeugmaschine 1 ist, ist der erste Schaltzustand A hier als Ausschaltzustand vorgesehen, in dem die Elektrowerkzeugmaschine 1 ausgeschaltet ist, wobei der zweite Schaltzustand E ein Einschaltzustand E ist, in dem die Elektrowerkzeugmaschine 1 eingeschaltet ist. Im Rahmen der Fig. 1 - 6 werden die Begriffe erster Schaltzustand A und Ausschaltzustand sowie zweiter Schaltzustand E und Einschaltzustand synonym verwendet.Here, since the electric switch 800 is the operation switch of the electric machine tool 1, the first switching state A is provided as the off state in which the power tool 1 is turned off, the second switching state E being the on state E in which the power tool 1 is turned on. As part of the Fig. 1 6 , the terms first switching state A and OFF state as well as second switching state E and ON state are used interchangeably.

Beim Verstellen des Betriebsmodusschalters 41 vom "Bohrbetrieb" oder vom "Bohrhammerbetrieb" in den Betriebszustand "Meißelbetrieb" wird der Schieber 42 mittels einer Nockenkontur (nicht gezeigt) des Betriebsmodusschalters 41 in die Verschieberichtung 43 verschoben. Dadurch zieht der Schieber 42 am Band 6, so dass die zweite Schaltvorrichtung 5 aus einem dritten Schaltzustand G gegen eine Rückstellkraft, die hier durch einen Pfeil 58 dargestellt ist, mittels des Schalthebels 53 in einen vierten Schaltzustand AR verstellt wird.When adjusting the operation mode switch 41 from the "drilling operation" or the "hammer drill operation" in the operating state "chisel operation" of the slider 42 is displaced by means of a cam contour (not shown) of the operating mode switch 41 in the direction of displacement 43. As a result, the slider 42 pulls on the band 6, so that the second switching device 5 from a third switching state G against a restoring force, which is here represented by an arrow 58, is adjusted by means of the shift lever 53 in a fourth switching state AR.

Im "Bohrbetrieb" oder "Bohrhammerbetrieb" darf ein Betriebsschalter 800 eines Bohrhammers 1 nicht arretierbar sein, damit sich dieser bei einem Verkanten eines Bohrers nicht unkontrolliert weiter dreht, so dass der Bediener des Bohrhammers geschützt ist. Im "Bohrbetrieb" oder "Bohrhammerbetrieb" muss der Betriebsschalter 800 daher notwendigerweise als Taster ausgebildet sein. Im Gegensatz dazu ist es im "Meißelbetrieb" bevorzugt, dass der Betriebsschalter 800 arretierbar ist. In diesem Betriebszustand ist es daher bevorzugt, dass der Betriebsschalter 800 als Wippschalter wirkt.In the "drilling operation" or "hammer drill operation", an operating switch 800 of a hammer drill 1 may not be locked so that it does not rotate uncontrollably when tilting a drill, so that the operator of the hammer drill is protected. In the "drilling operation" or "hammer drill operation", the operating switch 800 must therefore necessarily be designed as a push button. In contrast, in the "chisel mode", it is preferable that the operation switch 800 is lockable. In this operating state, it is therefore preferred that the operating switch 800 acts as a rocker switch.

Daher ist der Betriebsschalter 800 hier so vorgesehen, dass der dritte Schaltzustand G ein Grundzustand ist, in dem der Betriebsschalter 800 nicht arretierbar oder arretiert ist, und der eingestellt ist, wenn sich der Bohrhammer 1 im "Bohrbetrieb" oder "Bohrhammerbetrieb" befindet. Weiterhin ist der Betriebsschalter 800 hier so vorgesehen, dass der vierte Schaltzustand AR ein Arretierzustand ist, in dem der Betriebsschalter 800 arretierbar oder arretiert ist, und der eingestellt ist, wenn sich der Bohrhammer 1 im "Meißelbetrieb" befindet. Im Rahmen der Fig. 1 - 6 werden die Begriffe dritter Schaltzustand G und Grundzustand sowie vierter Schaltzustand AR und Arretierzustand daher synonym verwendet.Therefore, the operation switch 800 is provided here so that the third switching state G is a ground state in which the operation switch 800 is not lockable or locked, and which is set when the hammer drill 1 is in "drilling operation" or "hammer drill operation". Furthermore, the operation switch 800 is provided here so that the fourth switching state AR is a locking state in which the operation switch 800 is lockable or locked, and which is set when the hammer drill 1 is in "chiseling operation". As part of the Fig. 1 - 6 Therefore, the terms third switching state G and ground state and fourth switching state AR and locking state are used synonymously.

Bei gedrücktem erstem Schaltwippenteil 91 ist der Betriebsschalter 800 somit im Arretierzustand arretiert, wenn der Bohrhammer 1 eingeschaltet ist. Dann ist der Betriebsschalter 800 zwar durch Drücken des zweiten Schaltwippenteils 92 vom Einschaltzustand E in den Ausschaltzustand A verstellbar, wobei der Bohrhammer 1 ausgeschaltet wird. Aber der Betriebsschalter 800 verbleibt dann im Arretierzustand AR, so dass er weiterhin arretierbar ist.When pressed first rocker switch part 91 of the operating switch 800 is thus locked in the locked state when the hammer drill 1 is turned on. Then, the operating switch 800 is indeed adjustable by pressing the second rocker switch part 92 from the on state E to the off state A, wherein the hammer drill 1 is turned off. But the operation switch 800 then remains in the locked state AR, so that it is still lockable.

Beim Zurückstellen des Betriebsmodusschalters 41 vom Betriebszustand "Meißelbetrieb" in den "Bohrbetrieb" oder in den "Bohrhammerbetrieb" wird der Schieber 42 mithilfe der Druckfeder 44 gegen die Verschieberichtung 43 verschoben. Da das Band 6 längenbeständig ist, folgt es der Schiebebewegung des Schiebers 42, so dass der Haken 531 zurück gestellt wird, wobei die zweite Schaltvorrichtung 5 zurückgestellt wird, so dass der Betriebsschalter 800 von der Arretierposition AR in die Grundposition G zurückgestellt wird. Dabei wird die zweite Schaltvorrichtung 5 mittels der Rückstellkraft 58 in die Grundposition G zurück gestellt.When resetting the operating mode switch 41 from the operating state "chisel operation" in the "drilling operation" or in the "hammer drill operation", the slider 42 is moved by means of the compression spring 44 against the direction of displacement 43. Since the belt 6 is length-resistant, it follows the sliding movement of the slider 42, so that the hook 531 is reset, the second switching device 5 is reset, so that the operation switch 800 is returned from the locking position AR to the home position G. becomes. In this case, the second switching device 5 is reset by means of the restoring force 58 in the basic position G.

Der Betriebsschalter 800 sowie die Schaltwippe 9 sind durch Lösen und Abnehmen der Griffschale 31 von außen zugänglich.The operating switch 800 and the rocker switch 9 are accessible by loosening and removing the handle shell 31 from the outside.

Fig. 2 zeigt einen Ausschnitt aus der Elektrowerkzeugmaschine 1 der Fig. 1 , und zwar in (a) in einer perspektivischen und in (b) in einer Seitenansicht. Die Fig. 2 zeigt, dass am Betriebsschalter 800 Anschlüsse 82 zum Anschließen eines Stromkreises (nicht gezeigt), hier des Motorstromkreises, vorgesehen sind. Die Anschlüsse 82 sind zumindest teilweise außerhalb eines Schaltergehäuses 80 des Betriebsschalters 800 vorgesehen. Außerdem ist hier sichtbar, dass der Schalthebel 53 sowie ein erstes Signalmittel 85, welches hier als Winkelhebel ausgebildet ist und mit der Schaltwippe 9 zusammenwirkt, ebenfalls zumindest teilweise außerhalb des Gehäuses 80 vorgesehen sind, damit sie von außen zugänglich sind. Der Betriebsschalter 800 ist aber im Übrigen innerhalb des Schaltergehäuses 80 angeordnet und somit vor Staub und Feuchtigkeit geschützt. Außerdem ist der elektrische Schalter 800 dieser Ausführungsform als modulares Bauteil in einer Vielzahl verschiedener Elektrowerkzeugmaschinen 1 verwendbar. Und schließlich ist die Handhabung eines durch ein Schaltergehäuse 80 geschützten Bauteils einfach. Fig. 2 shows a section of the electric machine tool 1 of Fig. 1 in (a) in a perspective view and in (b) in a side view. The Fig. 2 shows that the operating switch 800 terminals 82 for connecting a circuit (not shown), here the motor circuit, are provided. The terminals 82 are provided at least partially outside a switch housing 80 of the operation switch 800. In addition, it is visible here that the shift lever 53 and a first signal means 85, which is designed here as an angle lever and cooperates with the rocker switch 9, are also provided at least partially outside of the housing 80 so that they are accessible from the outside. The operating switch 800 is, however, arranged inside the switch housing 80 and thus protected from dust and moisture. In addition, the electric switch 800 of this embodiment is usable as a modular component in a variety of power tool machines 1. And finally, the handling of a protected by a switch housing 80 component is easy.

Im Rahmen der Fig. 2 - 6 werden die Begriffe erstes Signalmittel 85 und Winkelhebel synonym verwendet.As part of the Fig. 2-6 the terms first signal means 85 and angle lever are used synonymously.

Fig. 3 zeigt in den Fig. 3 (a) - (c) den Betriebsschalter 800 des Bohrhammers 1 der Fig. 1 sowie die Schaltwippe 9, wobei sich die erste Schaltvorrichtung 8 des Betriebsschalters 800 im Ausschaltzustand A und die zweite Schaltvorrichtung 5 im Grundzustand G befinden. Fig. 3 shows in the Fig. 3 (a) - (c) the operating switch 800 of the hammer drill 1 of Fig. 1 and the rocker switch 9, wherein the first switching device 8 of the operating switch 800 in the off state A and the second switching device 5 are in the ground state G.

Die erste Schaltvorrichtung 8 umfasst hier zwei elektrische Kontakte 83 sowie elektrische Anschlüsse 82 zum Schließen des Motorstromkreises. Weiterhin umfasst sie ein erstes Stellmittel 81, welches mit dem Winkelhebel 85 zusammenwirkt.The first switching device 8 here comprises two electrical contacts 83 and electrical connections 82 for closing the motor circuit. Furthermore, it comprises a first adjusting means 81, which cooperates with the angle lever 85.

Durch Betätigen der Schaltwippe 9 ist der Winkelhebel 85, der am Schaltergehäuse 80 des Betriebsschalters 800 gelagert ist, um eine Winkelhebelachse 850 drehbar. Dafür weist er ein der Schaltwippe 9 zugewandtes Ende 851 sowie ein dem Betriebsschalter 800 zugewandtes Ende 852 auf. An seinem der Schaltwippe 9 zugewandten Ende 851 ist ein Befestigungsmittel 859 vorgesehen, an dem die Schaltwippe 9 drehbar befestigt ist. Das Befestigungsmittel 859 ist hier als ein Langloch ausgebildet, wobei an der Schaltwippe 9 ein Gegenbefestigungsmittel 99 vorgesehen ist, welches hier als ein an der Schaltwippe 9 angeordneter Verbindungsstift ausgebildet ist. Grundsätzlich ist aber auch eine andere Dreh- oder Schiebeverbindung möglich.By actuating the rocker switch 9, the angle lever 85, which is mounted on the switch housing 80 of the operating switch 800, is rotatable about an angle lever axis 850. For this purpose, it has an end 851 facing the switching rocker 9 and an end 852 facing the operating switch 800. At its the rocker switch 9 facing the end 851, a fastening means 859 is provided, on which the rocker switch 9 is rotatably mounted. The fastening means 859 is designed here as a slot, wherein on the rocker switch 9, a counter-fastening means 99 is provided, which is designed here as a arranged on the rocker switch 9 connecting pin. In principle, however, another rotary or sliding connection is possible.

An seinem dem Betriebsschalter 800 zugewandten Ende 852 ist der Winkelhebel 85 stoßzahnähnlich ausgebildet. Das dem Betriebsschalter 800 zugewandte stoßzahnähnlich ausgebildete Ende 852 des Winkelhebels wird im Rahmen der Fig. 3 - 6 als Stoßzahn bezeichnet. Der Stoßzahn 852 weist ein der zweiten Schaltvorrichtung 5 zugewandtes Ende 853 sowie ein der zweiten Schaltvorrichtung 5 abgewandtes Ende 854 auf. Das der zweiten Schaltvorrichtung 5 abgewandte Ende 854 liegt an einem Anlagemittel 811 des ersten Stellmittels 81 an. Das erste Stellmittel 81 ist hier als Schiebemittel ausgebildet. Im Rahmen der Fig. 3 - 6 werden daher die Begriffe erstes Stellmittel 81 sowie Schiebemittel synonym verwendet. Anstelle eines Schiebemittels ist das erste Stellmittel 81 aber auch als Drehmittel ausbildbar.At its the operating switch 800 facing the end 852 of the angle lever 85 is formed like a tooth. The operating switch 800 facing the tooth-like end 852 of the angle lever is in the context of Fig. 3 - 6 referred to as tusk. The tusk 852 has an end 853 facing the second switching device 5 and an end 854 facing away from the second switching device 5. The second switching device 5 facing away from the end 854 is applied to a bearing means 811 of the first actuating means 81 at. The first adjusting means 81 is designed here as a sliding means. As part of the Fig. 3 - 6 Therefore, the terms first actuating means 81 and sliding means are used synonymously. Instead of a sliding means, however, the first adjusting means 81 can also be embodied as a rotating means.

Das Schiebemittel 81 ist gegen die Kraft eines ersten Kraftmittels (nicht gezeigt) verschiebbar.The pushing means 81 is slidable against the force of a first power means (not shown).

Durch Betätigen des ersten Schaltwippenteils 91 wird die Schaltwippe 9 um eine Schaltwippenachse 90 in eine Betätigungsrichtung 907 gedreht. Dabei wird der Winkelhebel 85 um die Winkelhebelachse 850 in eine Winkelhebelrichtung 857 gedreht. Dadurch wird das Schiebemittel 81 in die Schieberichtung 84 verschoben, wobei die elektrischen Kontakte 83 ebenfalls in die Schieberichtung 84 verschoben werden, bis sie an den elektrischen Anschlüssen 82 anliegen und diese verbinden, so dass der Motorstromkreis geschlossen ist. Dadurch wird der Betriebsschalter 800 von der Ausschaltposition A in die Einschaltposition E verstellt.By actuating the first rocker switch part 91, the rocker switch 9 is rotated about a rocker switch axis 90 in an actuating direction 907. In this case, the angle lever 85 is rotated about the angle lever axis 850 in a Winkelhebelrichtung 857. Thereby, the sliding means 81 is displaced in the sliding direction 84, wherein the electrical contacts 83 are also displaced in the sliding direction 84 until they abut against the electrical terminals 82 and connect them, so that the motor circuit closed is. As a result, the operating switch 800 is moved from the switch-off position A to the switch-on position E.

Fig. 4 zeigt in den Fig. 4 (a) - (c) den Betriebsschalter 800 der Fig. 3 , wobei sich die erste Schaltvorrichtung 8 des Betriebsschalters 800 im Einschaltzustand E und die zweite Schaltvorrichtung 5 im Grundzustand G befinden. Fig. 4 shows in the Fig. 4 (a) - (c) the operation switch 800 of Fig. 3 , wherein the first switching device 8 of the operating switch 800 in the on state E and the second switching device 5 are in the ground state G.

Aufgrund der Rückstellkraft des ersten Kraftmittels wird das Schiebemittel 81 im Grundzustand G bei Loslassen der Schaltwippe 9 gegen die Schieberichtung 84 verschoben, wobei die elektrischen Kontakte 83 gegen die Schieberichtung 84 verschoben werden, so dass sie von den elektrischen Anschlüssen 82 weggeschoben werden und der Motorstromkreis geöffnet wird. Dabei wird der der Schaltwippe 9 abgewandte Teil 854 des Winkelhebels 85 mittels des Anlagemittels 811 des Schiebemittels 81 gegen die Schieberichtung 84 verschoben, wobei der Winkelhebel 85 gegen die Winkelhebelrichtung 857 gedreht wird, und wobei die Schaltwippe 9 gegen die Betätigungsrichtung 907 gedreht wird. Dadurch wird der Betriebsschalter 800 von der Einschaltposition E in die Ausschaltposition A zurück gestellt.Due to the restoring force of the first force means, the sliding means 81 is displaced in the ground state G when releasing the rocker switch 9 against the sliding direction 84, wherein the electrical contacts 83 are moved against the sliding direction 84, so that they are pushed away from the electrical terminals 82 and the motor circuit opened becomes. In this case, the rocker 9 remote from the part 854 of the angle lever 85 is moved by means of the abutment means 811 of the sliding means 81 against the sliding direction 84, wherein the angle lever 85 is rotated against the angle lever 857, and wherein the rocker switch 9 is rotated against the actuating direction 907. Thereby, the operation switch 800 is returned from the switch-on position E to the switch-off position A.

In der Zusammenschau der Fig. 3 und 4 ist erkennbar, dass der Winkelhebel 85 beim Verstellen der ersten Schaltvorrichtung 8 vom Ausschaltzustand A in den Einschaltzustand E und zurück frei um die Winkelhebeldrehachse 85 drehbar ist, wenn sich die zweite Schaltvorrichtung 5 im Grundzustand G befindet. Im Grundzustand G ist der Betriebsschalter 800 daher weder im Einschaltzustand E noch im Ausschaltzustand A arretierbar oder arretiert.In the synopsis of Fig. 3 and 4 It can be seen that the angle lever 85 during the adjustment of the first switching device 8 from the OFF state A in the ON state E and back is freely rotatable about the Winkelhebeleldrehachse 85 when the second switching device 5 is in the ground state G. In the basic state G, the operating switch 800 can therefore be locked or locked neither in the switch-on state E nor in the switch-off state A.

In der hier gezeigten Ausführungsform wirkt der Betriebsschalter 800 daher im Grundzustand G immer wie ein Taster.In the embodiment shown here, the operating switch 800 therefore always acts in the basic state G like a push-button.

Fig. 5 zeigt in den Fig. 5 (a) - (c) den Betriebsschalter 800 der Fig. 3 , wobei sich die erste Schaltvorrichtung 8 des Betriebsschalters 800 im Ausschaltzustand A und die zweite Schaltvorrichtung 5 im Arretierzustand AR befinden. Fig. 5 shows in the Fig. 5 (a) - (c) the operation switch 800 of Fig. 3 , wherein the first switching device 8 of the operating switch 800 in the off state A and the second switching device 5 are in the locked state AR.

Die zweite Schaltvorrichtung 5 umfasst ein zweites Stellmittel 54, welches hier als Arretierklinke ausgebildet ist und am Schalthebel 53 um eine Arretierklinkenachse 540 drehbar gelagert ist. Im Rahmen der Fig. 3 - 6 werden die Begriffe zweites Stellmittel 54 und Arretierklinke synonym verwendet.The second switching device 5 comprises a second adjusting means 54, which is designed here as a locking pawl and is rotatably mounted on the shift lever 53 about a locking pawl axis 540. As part of the Fig. 3 - 6 the terms second actuating means 54 and locking pawl are used synonymously.

Der Schalthebel 53 ist am Schaltergehäuse 80 des Betriebsschalters 800 um eine Schalthebelachse 530 drehbar gelagert. Beim Verstellen des Betriebsmodus vom "Bohrbetrieb" oder "Bohrhammerbetrieb" in den "Meißelbetrieb" wird die zweite Schaltvorrichtung 5 vom Grundzustand G in den Arretierzustand AR verstellt, indem der Schalthebel 53 in eine Schalthebeldrehrichtung 537 gegen die Kraft 58 des zweiten Kraftmittels 56, welches hier als Druckfeder ausgebildet ist, um die Schalthebelachse 530 gedreht wird. Da die Arretierklinke 54 am Schalthebel 53 gelagert ist, wird sie mit dem Schalthebel 53 gedreht.The shift lever 53 is rotatably mounted on the switch housing 80 of the operation switch 800 about a shift lever axis 530. When adjusting the operating mode of the "drilling operation" or "hammer drill operation" in the "chisel operation", the second switching device 5 is moved from the ground state G in the locked state AR by the shift lever 53 in a Schalthebeleldreirichtung 537 against the force 58 of the second power means 56, which here is designed as a compression spring to the shift lever axis 530 is rotated. Since the locking pawl 54 is mounted on the shift lever 53, it is rotated by the shift lever 53.

An der Arretierklinke 54 ist ein Hebemittel 52 angeordnet, welches hier als ein Dorn ausgebildet ist. Im Rahmen der Fig. 3 - 6 werden die Begriffe Hebemittel 52 und Dorn synonym verwendet. Der Dorn 52 ist an der dem Stoßzahn 852 zugewandten Seite der Arretierklinke 54 angeordnet. An ihrer dem Stoßzahn 852 abgewandten Seite wird die Arretierklinke 54 mittels einer Druckfeder 55 gegen den Schalthebel 53 gedrückt.At the locking pawl 54, a lifting means 52 is arranged, which is designed here as a mandrel. As part of the Fig. 3 - 6 the terms lifting means 52 and mandrel are used synonymously. The mandrel 52 is disposed on the tusk 852 side facing the locking pawl 54. On its side facing away from the tusk 852, the locking pawl 54 is pressed against the shift lever 53 by means of a compression spring 55.

Die Arretierklinke 54 wird beim Verstellen der zweiten Schaltvorrichtung 5 vom Grundzustand G in den Arretierzustand AR solange mit dem Schalthebel 53 gedreht, bis der Dorn 52 im Ausschaltzustand A der ersten Schaltvorrichtung 8 im bogenförmigen Bereich des Stoßzahns 852 angeordnet ist.When the second switching device 5 is moved from the basic state G into the locked state AR, the locking pawl 54 is rotated with the shift lever 53 until the spike 52 is arranged in the arcuate region of the tusk 852 in the switched-off state A of the first switching device 8.

Beim Verstellen der ersten Schaltvorrichtung 8 vom Ausschaltzustand A in den Einschaltzustand E wird der Winkelhebel 85 um die Winkelhebelachse 850 in die Winkelhebelrichtung 857 gedreht, wobei auch der Stoßzahn 852 in die Winkelhebelrichtung 857 gedreht wird und aufgrund seiner Bogenform entlang dem Dorn 52 gleitet, ohne durch diesen behindert zu werden, bis die Arretierklinke 54 mit einer der ersten Schaltvorrichtung 8 zugewandten Stirnfläche 541 (s. Fig. 4(b) , (c) ) an einem Arretiermittel 812 der ersten Schaltvorrichtung 8 anliegt. Die Druckfeder 55 drückt die Stirnfläche 541 der Arretierklinke 54 dabei gegen das Arretiermittel 812 des Schaltschiebers 81. In diesem Arretierzustand AR ist der Schaltschieber 81 nicht durch die Kraft des ersten Kraftmittels gegen die Schieberichtung 84 zurückschiebbar.When adjusting the first switching device 8 from the OFF state A in the ON state E, the angle lever 85 is rotated about the bell crank shaft 85 in the Winkelhebelrichtung 857, wherein the tusk 852 is rotated in the Winkelhebelrichtung 857 and due to its curved shape along the mandrel 52 slides through To be hindered until the locking pawl 54 with one of the first switching device. 8 facing end face 541 (s. Fig. 4 (b) . (c) ) abuts a locking means 812 of the first switching device 8. The compression spring 55 presses the end face 541 of the locking pawl 54 against the locking means 812 of the slide switch 81. In this locking state AR, the slide switch 81 is not pushed back against the sliding direction 84 by the force of the first force means.

Fig. 6 zeigt in den Fig. 6 (a) - (c) den Betriebsschalter 800 der Fig. 3 , wobei sich die erste Schaltvorrichtung 8 des Betriebsschalters 800 im Einschaltzustand E und die zweite Schaltvorrichtung 5 im Arretierzustand AR befinden. Fig. 6 shows in the Fig. 6 (a) - (c) the operation switch 800 of Fig. 3 , wherein the first switching device 8 of the operating switch 800 in the on state E and the second switching device 5 are in the locked state AR.

Beim Loslassen der Schaltwippe 9 wird das Schiebemittel 81 aufgrund der Rückstellkraft des ersten Kraftmittels gegen die Schieberichtung 84 gedrückt oder gezogen. Da das Anlagemittel 811 des Schiebemittels 81 an dem der zweiten Schaltvorrichtung 5 abgewandten Ende 854 des Stoßzahns 852 anliegt, wird dabei der Winkelhebel 85 zurück gedrückt. Da jedoch die Stirnfläche 541 der Arretierklinke an dem Arretiermittel 812 der ersten Schaltvorrichtung 8 anliegt, ist das Schiebemittel 81 nicht gegen die Schieberichtung 84 zurückschiebbar. Gleichzeitig liegt nun der Stoßzahn 852 des Winkelhebels 85 mit seinem der zweiten Schaltvorrichtung 5 zugewandten Ende 853 am Dorn 52 an, so dass er nicht zurückgedreht werden kann.When releasing the rocker switch 9, the sliding means 81 is pressed or pulled against the sliding direction 84 due to the restoring force of the first power means. Since the abutment means 811 of the sliding means 81 bears against the end 854 of the tusk 852 facing away from the second switching device 5, the angle lever 85 is pressed back. However, since the end surface 541 of the locking pawl is applied to the locking means 812 of the first switching device 8, the pushing means 81 can not be pushed back against the sliding direction 84. At the same time, the tusk 852 of the angle lever 85 now bears with its end 853 facing the second switching device 5 on the mandrel 52, so that it can not be turned back.

Durch Drücken des zweiten Schaltwippenteils 92 wird der Winkelhebel 85 dagegen mit ausreichend großer Kraft durch den Bediener um die Winkelhebelachse 850 gegen die Winkelhebelrichtung 857 gedreht. Dabei hebt das der zweiten Schaltvorrichtung 5 zugewandte Ende 853 des Stoßzahns 852 das Hebemittel 52 an, so dass die Arretierklinke 54 sich um die Arretierklinkenachse 540 in eine Löserichtung dreht und die Stirnfläche 541 der Arretierklinke 54 vom Arretiermittel 812 abgehoben wird. Dabei wird die Druckfeder 55 gegen ihre Rückstellkraft zunächst zusammengedrückt. Dann gleitet das Hebemittel 52 entlang dem Stoßzahn 852, bis es im Ausschaltzustand A der ersten Schaltvorrichtung 8 wieder im bogenförmigen Bereich des Stoßzahns 852 angeordnet ist, wobei die Druckfeder 55 sich zumindest teilweise entspannt.By pressing the second rocker switch part 92, however, the angle lever 85 is rotated with sufficient force by the operator to the angle lever axis 850 against the angle lever 857 direction. In this case, the second switching device 5 facing the end 853 of the tusk 852 lifts the lifting means 52, so that the locking pawl 54 rotates about the locking pawl 540 in a release direction and the end face 541 of the locking pawl 54 is lifted from the locking means 812. The compression spring 55 is first compressed against its restoring force. Then, the lifting means 52 slides along the tusk 852 until it is again in the arcuate portion of the tusk 852 in the OFF state A of the first switching device 8, wherein the compression spring 55 at least partially relaxes.

Aufgrund der Rückstellkraft des ersten Kraftmittels wird das Schiebemittel 81 dabei gegen die Schieberichtung 84 verschoben, so dass der Motorstromkreis geöffnet wird. Dabei wird der der Schaltwippe 9 abgewandte Teil 854 des Winkelhebels 85 mittels des Anlagemittels 811 des Schiebemittels 81 gegen die Schieberichtung 84 verschoben, wobei der Winkelhebel 85 gegen die Winkelhebelrichtung 857 gedreht wird. Dadurch wird der Betriebsschalter 800 von der Einschaltposition E in die Ausschaltposition A zurück gestellt.Due to the restoring force of the first force means, the sliding means 81 is displaced against the sliding direction 84, so that the motor circuit is opened. In this case, the rocker 9 facing away from the part 854 of the angle lever 85 is moved by means of the abutment means 811 of the sliding means 81 against the sliding direction 84, wherein the angle lever 85 is rotated against the angle lever 857 direction. Thereby, the operation switch 800 is returned from the switch-on position E to the switch-off position A.

Die erste Schaltvorrichtung 8 des Betriebsschalters 800 befindet sich dann wieder im Ausschaltzustand A, wobei sich die zweite Schaltvorrichtung 5 im Arretierzustand AR befindet (s. Fig. 5 ).The first switching device 8 of the operating switch 800 is then again in the off state A, wherein the second switching device 5 is in the locked state AR (s. Fig. 5 ).

Im Arretierzustand AR ist der Betriebsschalter 800 daher im Ausschaltzustand A arretierbar, indem er in den Einschaltzustand E verstellt wird. Im Einschaltzustand E ist er dagegen mittels der zweiten Schaltvorrichtung 5 arretiert. Der Betriebsschalter 800 wirkt daher im Arretierzustand AR wie ein Wippschalter.In the locked state AR, the operation switch 800 is therefore lockable in the OFF state A, by being adjusted to the ON state E. In the on state E, however, he is locked by means of the second switching device 5. The operation switch 800 therefore acts in the locked state AR as a rocker switch.

Außerdem ist der Betriebsschalter 800 nur im Arretierzustand AR durch Betätigen des zweiten Schaltwippenteils 92 vom Einschaltzustand E in den Ausschaltzustand A verstellbar. Im Grundzustand G, in dem der Betriebsschalter 800 als Taster wirkt, wird die Schaltwippe 9 hingegen beim Zurückstellen der ersten Schaltvorrichtung 8 automatisch um die Schaltwippenachse 90 gegen die Betätigungsrichtung 907 zurückgedreht (s. Fig. 4 ).In addition, the operating switch 800 is only in the locked state AR by operating the second rocker switch part 92 from the ON state E in the OFF state A adjustable. In the basic state G, in which the operating switch 800 acts as a button, the switching rocker 9, however, when returning the first switching device 8 is automatically rotated back to the rocker axis 90 against the actuating direction 907 (s. Fig. 4 ).

Beim Zurückstellen des Betriebsschalters vom "Meißelbetrieb" in den "Bohrbetrieb" oder "Bohrhammerbetrieb" wird der Schalthebel 53 aufgrund der Rückstellkraft des zweiten Kraftmittels 56 um die Schalthebelachse 530 gegen die Schalthebelrichtung 537 gedreht, wobei das Band 6 zurückgestellt wird. Da die Schaltklinke 54 am Schalthebel 53 gelagert ist, wird sie gemeinsam mit dem Schalthebel 53 gedreht.When the operating switch is reset from the "chiseling mode" to the "drilling mode" or "hammering operation", the shift lever 53 is rotated about the shift lever axis 530 against the shift lever direction 537 due to the restoring force of the second power means 56, returning the belt 6. Since the pawl 54 is mounted on the shift lever 53, it is rotated together with the shift lever 53.

Dabei wird die Stirnfläche 541 der Arretierklinke 54 um die Arretierklinkenachse 540 gedreht, wobei sie sich vom Arretiermittel 812 des Schiebemittels 81 wegdreht, und zwar unabhängig davon, ob sich die erste Schaltvorrichtung 8 im Einschaltzustand E oder im Ausschaltzustand A befindet. Ausgehend vom Einschaltzustand E wird durch das Wegdrehen der Stirnfläche 541 bewirkt, dass das Schiebemittel 81 aufgrund der Rückstellkraft des ersten Kraftmittels gegen die Schieberichtung 84 verschoben wird, wobei der Winkelhebel 85 gegen die Winkelhebelrichtung 857 gedreht wird, wobei die Schaltwippe 9 gegen die Schaltwippenrichtung 907 gedreht wird, und wobei die erste Schaltvorrichtung 8 in den Ausschaltzustand A verstellt wird. Die zweite Schaltvorrichtung 5 befindet sich dann im Grundzustand G.In this case, the end face 541 of the locking pawl 54 is rotated about the locking pawl axis 540, wherein it rotates away from the locking means 812 of the sliding means 81, regardless of whether the first switching device 8 is in the on state E or in the off state A. Starting from the ON state E is caused by the turning away of the end face 541 that the sliding means 81 is moved due to the restoring force of the first power means against the sliding direction 84, wherein the angle lever 85 is rotated against the Winkelhebelrichtung 857, wherein the rocker switch 9 is rotated against the Schalttwippenrichtung 907 is, and wherein the first switching device 8 is moved to the off state A. The second switching device 5 is then in the ground state G.
