Description

Die Erfindung betrifft eine Vorrichtung zum Verriegeln eines Batteriepacks in einer Führung eines Elektrowerkzeugs gemäß dem Oberbegriff des Anspruchs 1 sowie ein Elektrowerkzeug gemäß dem Oberbegriff des Anspruchs 10.The invention relates to a device for locking a battery pack in a guide of a power tool according to the preamble of claim 1 and a power tool according to the preamble of claim 10.

Stand der TechnikState of the art

Als nächstliegender Stand der Technik wird das Dokument US 6 376 942 B1 betrachtet.The closest prior art is the document US Pat. No. 6,376,942 B1 considered.

Netzunabhängige handgeführte Elektrowerkzeuge, die von einem Batteriepack mit Strom versorgt werden, sind gewöhnlich mit einer Verriegelungsvorrichtung versehen, um den Batteriepack im Betrieb in Bezug zum Elektrowerkzeug festzuhalten. Um zu vermeiden, dass sich der Batteriepack unbeabsichtigt vom Elektrowerkzeug löst, wenn er nicht ordnungsgemäß mit diesem verriegelt ist, ist bei einigen größeren und schwereren Elektrowerkzeugen der Anmelderin zudem bereits eine Vorrichtung der eingangs genannten Art vorgesehen, die eine auch als Doppelverriegelung bezeichnete zweistufige Verriegelung ermöglicht. Dabei wird ein federbelasteter Riegel des Elektrowerkzeugs beim Einschieben des Batteriepacks in die Führung durch die Federkraft nacheinander mit zwei in Einschubrichtung hintereinander im Batteriepack ausgesparten Rastausnehmungen in Eingriff gebracht. Beim Eingriff des Riegels in die erste Rastausnehmung, d.h. in der vorderen Verriegelungsposition, wird der Batteriepack nur in Bezug zum Elektrowerkzeug gesichert, während eine elektrische Verbindung erst beim Eingriff des Riegels in die zweite Rastausnehmung, d.h. in der hinteren Verriegelungsposition, hergestellt wird. Zur Entnahme des Batteriepacks ist das Elektrowerkzeug mit einem Entriegelungsorgan versehen, das gewöhnlich als Drucktaster ausgebildet ist und betätigt wird, um den Batteriepack vor der Entnahme zu entriegeln. Mit der bekannten Vorrichtung kann zwar verhindert werden, dass sich der Batteriepack ungewollt vom Elektrowerkzeug löst, wenn der Riegel nicht oder nicht ordnungsgemäß in die hintere Rastausnehmung eingreift, zum Beispiel weil der Batteriepack vom Benutzer in der Führung nicht ganz bis in die hintere Verriegelungsposition geschoben worden ist. Wenn jedoch der Benutzer zur Entnahme des Batteriepacks das Entriegelungsorgan betätigt und betätigt hält, oder wenn sich beim Entriegeln das Entriegelungsorgan oder der Riegel in seiner Entriegelungsposition verklemmt, kann der Batteriepack unbeabsichtigt aus der Führung herausgleiten und abstürzen, sofern zu diesem Zeitpunkt die Führung entgegen der Einschubrichtung schräg nach unten weist und der Batteriepack nicht festgehalten wird. Insbesondere bei Arbeiten in großer Höhe birgt dies die Gefahr von schweren Verletzungen anderer Personen.Off-line power tools that are powered by a battery pack are usually provided with a locking device to hold the battery pack in operation relative to the power tool. In order to avoid that the battery pack unintentionally detached from the power tool, if he is not properly locked with this, in some larger and heavier power tools of the Applicant also already a device of the type mentioned is provided, which also allows a double locking called two-stage locking , In this case, a spring-loaded latch of the power tool when inserting the battery pack in the guide by the spring force is successively engaged with two recessed in the insertion direction in the battery pack recessed engagement. Upon engagement of the bolt in the first locking recess, ie in the front locking position, the battery pack is secured only in relation to the power tool, while an electrical connection is made only upon engagement of the bolt in the second recess, ie in the rear locking position. To remove the battery pack, the power tool is provided with a Entriegelungsorgan that usually designed as a push-button is and is pressed to unlock the battery pack prior to removal. Although with the known device can be prevented that the battery pack unintentionally detached from the power tool when the latch does not or not properly engaged in the rear recess, for example because the battery pack has not been pushed by the user in the guide not quite up to the rear locking position is. However, if the user to remove the battery pack actuates the unlocking organ and holds pressed, or if unlocking the unlocking or the bolt jammed in its unlocked position, the battery pack can inadvertently slide out of the guide and crash, if at this time the leadership against the insertion direction points diagonally downwards and the battery pack is not held. Especially when working at high altitude, this carries the risk of serious injury to other people.

Die Druckschrift US-B1-6,376,942 offenbart ein batteriebetriebenes Bohrgerät, bei dem ein Batteriepack in zwei Verriegelungsstellungen an dem Gehäuse ansetzbar ist und ebenfalls nur in der zweiten und nicht in der ersten Verriegelungsstellung elektrisch mit dem Antriebsmotor des Bohrgerätes verbunden ist. Der Anschluß des Batteriepacks am Gehäuse des Bohrgerätes ist so vorgesehen, dass es zu keiner Relativbewegung zwischen dem am Batteriepack angeordneten Stecker und dem an dem Bohrgerät angeordneten Gegenstecker kommt, wenn das Bohrgerät Erschütterungen ausgesetzt ist. Jedoch sichern auch bei diesem Bohrgerät die beiden Verriegelungsstellungen den Batteriepack nicht gegen unbeabsichtigtes Abstürzen.The publication US B1-6,376,942 discloses a battery-operated drilling rig in which a battery pack can be attached to the housing in two locking positions and is also electrically connected to the drive motor of the drilling rig only in the second and not in the first locking position. The connection of the battery pack to the housing of the drill is provided so that there is no relative movement between the plug arranged on the battery pack and the mating plug arranged on the drill when the drill is subjected to shocks. However, even with this drill the two locking positions do not secure the battery pack against accidental crashes.

Vorteile der ErfindungAdvantages of the invention

Da sich bei der Entnahme des Batteriepacks der Riegel mit diesem in die vordere Verriegelungsposition mitbewegt und somit die Verriegelung des Batteriepacks zwischen den beiden Verriegelungspositionen aufrecht erhält, bietet die erfindungsgemäße Vorrichtung mit den im Anspruch 1 genannten Merkmalen den Vorteil, dass eine unbeabsichtigte Bewegung des Batteriepacks in Entnahmerichtung über die vordere Verriegelungsposition hinaus und damit ein Herausgleiten aus der Führung bis zu einer erneuten Betätigung des Entriegelungsorgans in der vorderen Verriegelungsposition verhindert wird.Since with the removal of the battery pack, the bolt moves with this in the front locking position and thus maintains the locking of the battery pack between the two locking positions, the device according to the invention with the features mentioned in claim 1 has the advantage that an unintentional movement of the battery pack in Removal direction beyond the front locking position and thus a Slipping out of the guide is prevented until re-actuation of the Entriegelungsorgans in the front locking position.

Vorzugsweise bleibt das Entriegelungsorgan zwischen der hinteren Verriegelungsposition und der vorderen Verriegelungsposition in einer betätigten Stellung, in der es sich nicht weiter bewegen lässt, und kehrt erst wieder in eine unbetätigte Stellung zurück, wenn der Batteriepack die vordere Verriegelungsposition erreicht. Eine erneute Betätigung des Entriegelungsorgans gestattet es dann, den Riegel aus dem Eingriff mit dem Batteriepack auszurücken, um die Verriegelung zwischen dem Batteriepack und dem Elektrowerkzeug zur Entnahme des Batteriepacks vollständig aufzuheben.Preferably, the unlocking member remains between the rear locking position and the front locking position in one actuated position in which it can not be moved, and only returns to an unactuated position when the battery pack reaches the front locking position. Re-actuation of the unlocking member then allows disengaging the latch from engagement with the battery pack to completely release the latch between the battery pack and the power tool for removal of the battery pack.

Vorzugsweise sind der Riegel und das Entriegelungsorgan als Einheit ausgebildet und bilden zweckmäßig die beiden Arme eines zweiarmigen Hebels, dessen einer Hebelarm in der unbetätigten Stellung über ein Gehäuse des Elektrowerkzeugs übersteht und als Entriegelungsorgan dient, während sein anderer Hebelarm als Riegel dient und mit einer Ausnehmung im Batteriepack in Eingriff tritt.Preferably, the latch and the unlocking member are formed as a unit and suitably form the two arms of a two-armed lever, one lever arm protrudes in the unactuated position via a housing of the power tool and serves as an unlocking, while his other lever arm serves as a bolt and with a recess in the Battery pack engages.

Um die Verriegelung zwischen der hinteren Verriegelungsposition und der vorderen Verriegelungsposition aufrecht zu erhalten, ist der Riegel gemäß einer vorteilhaften Ausgestaltung der Erfindung in der hinteren Verriegelungsposition betätigbar, um ihn aus einem Verriegelungseingriff mit dem Elektrowerkzeug auszurücken, so dass er sich zusammen mit dem Batteriepack in die vordere Verriegelungsposition mitbewegen kann, wo er erneut betätigbar ist, um ihn jetzt aus dem Eingriff mit dem Batteriepack auszurücken.In order to maintain the lock between the rear locking position and the front locking position, the latch according to an advantageous embodiment of the invention in the rear locking position is operable to disengage it from a locking engagement with the power tool, so that it together with the battery pack in the move forward lock position, where it is again operable to disengage it now out of engagement with the battery pack.

Um einerseits eine Betätigung des Entriegelungsorgans in der hinteren Verriegelungsposition und der vorderen Verriegelungsposition und andererseits dazwischen ein Mitbewegen des Riegels mit dem Batteriepack zu ermöglichen, sieht eine weitere vorteilhafte Ausgestaltung der Erfindung vor, dass der Riegel in der vorderen und hinteren Verriegelungsposition mit einem ersten Bewegungsfreiheitsgrad beweglich ist, der es erlaubt, ihn aus dem Verriegelungseingriff mit dem Batteriepack bzw. mit dem Elektrowerkzeug auszurücken, und dazwischen mit einem zweiten Bewegungsfreiheitsgrad beweglich ist, der es ihm erlaubt, sich zusammen mit dem Batteriepack in Bezug zum Elektrowerkzeug zu bewegen und dabei vorzugsweise in der betätigten Stellung zu bleiben.On the one hand to allow actuation of the Entriegelungsorgans in the rear locking position and the front locking position and on the other hand between moving the bolt with the battery pack, provides a further advantageous embodiment of the invention, that the bolt in the front and rear locking position with a first degree of freedom of movement is movable, which allows it to disengage from the locking engagement with the battery pack or with the power tool, and is movable therebetween with a second degree of freedom that allows it to move together with the battery pack with respect to the power tool, preferably in to remain in the actuated position.

Dazu ist der Riegel zweckmäßig entlang einer Führungskulisse des Elektrowerkzeugs verschiebbar, die in Abhängigkeit von der Riegelposition unterschiedliche Bewegungen zulässt. Bevorzugt ist der Riegel in der in der vorderen und hinteren Verriegelungsposition drehbar und zwischen diesen Positionen in Richtung der Führung linear beweglich. Die Führungskulisse ist vorzugsweise so ausgebildet, dass der zweiarmige Hebel in der vorderen und hinteren Verriegelungsposition jeweils mit überstehenden Achszapfen in einen Abschnitt der Führungskulisse eingreift, der im Wesentlichen quer zur Verschieberichtung in der Führung ausgerichtet ist, so dass sich der Riegel in diesen Abschnitten durch Betätigung des Entriegelungsorgans um unterschiedliche Drehachsen drehen lässt, um ihn aus dem Verriegelungseingriff mit dem Batteriepack bzw. mit dem Elektrowerkzeug auszurücken.For this purpose, the bolt is expediently displaceable along a guide slot of the power tool, which allows different movements depending on the locking position. Preferably, the latch is rotatable in the in the front and rear locking position and linearly movable between these positions in the direction of the guide. The guide slot is preferably formed so that the two-armed lever engages in the front and rear locking position with protruding stub axles in a portion of the guide slot, which is aligned substantially transverse to the direction in the guide, so that the bolt in these sections by actuation of the Entriegelungsorgans rotate about different axes of rotation to disengage it from the locking engagement with the battery pack or with the power tool.

Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass das Elektrowerkzeug eine auf den Riegel einwirkende Feder aufweist, die diesen vorzugsweise zusammen mit dem Batteriepack in die vordere Verriegelungsposition bewegt, sobald das Entriegelungsorgan in der hinteren Verriegelungsposition betätigt worden ist. Dadurch wird unmittelbar im Anschluss an die Betätigung des Entriegelungsorgans automatisch für eine sichere Trennung der elektrischen Kontakte des Batteriepacks und des Elektrowerkzeugs gesorgt und dieser nicht-betriebsbereite Zustand für den Benutzer deutlich sichtbar gemacht. Außerdem bewirkt die Feder darüber hinaus auch noch, dass der Batteriepack in die vordere Verriegelungsposition zurück bewegt wird, wenn er beim Einschieben in die Führung in der hinteren Verriegelungsposition nicht ordnungsgemäß verriegelt worden ist, wodurch diese Tatsache dem Benutzer ebenfalls bewusst gemacht wird.A further preferred embodiment of the invention provides that the power tool has a force acting on the bolt spring, which preferably moves this together with the battery pack in the front locking position as soon as the unlocking member has been operated in the rear locking position. As a result, a safe separation of the electrical contacts of the battery pack and the power tool is automatically taken care of immediately following the operation of the Entriegelungsorgans and clear this non-operational state for the user made visible. In addition, the spring also causes the battery pack to be moved back to the front locking position if it has not been properly locked when inserted into the guide in the rear locking position, thus also making the user aware of this fact.

Wie in den Figuren 1 bis 6 dargestellt, weist das Elektrowerkzeug 4 am freien unteren Ende seines Griffteils 8 eine ausgesparte Führungsnut 10 auf, in die sich eine am oberen Ende des Batteriepacks 6 angeordnete Führungsschiene 12 mit einem zum Querschnitt der Führungsnut 10 komplementären Querschnitt einschieben lässt, um den Batteriepack 6 mit dem Elektrowerkzeug 4 zu verbinden.As in the FIGS. 1 to 6 shown, the power tool 4 at the lower free end of its handle part 8 has a recessed guide groove 10 into which a arranged at the upper end of the battery pack 6 guide rail 12 can be inserted with a cross-section of the guide groove 10 complementary cross section to the battery pack 6 with the Power tool 4 to connect.

Die Einschubbewegung der Führungsschiene 12 in die Führungsnut 10 wird durch zusammenwirkende Anschlagflächen 14, 16 an den in Einschubrichtung hinteren Enden der Führungsschiene 12 bzw. Führungsnut 10 begrenzt, die gegeneinander anliegen, wenn der Batteriepack 6 in einer in Fig. 1 dargestellten hinteren Verriegelungsposition ordnungsgemäß mit dem Elektrowerkzeug 4 verriegelt und eine elektrische Verbindung zwischen Anschlusskontakten eines Stromspeichers des Batteriepacks 6 und einem Stromkreis eines Verbrauchers des Elektrowerkzeugs 4 hergestellt ist.The insertion movement of the guide rail 12 in the guide groove 10 is limited by cooperating stop surfaces 14, 16 at the rear in the insertion direction of the guide rail 12 and guide groove 10 which abut against each other when the battery pack 6 in a in Fig. 1 shown locked rear locking position properly with the power tool 4 and an electrical connection between terminals of a power storage of the battery pack 6 and a circuit of a consumer of the power tool 4 is made.

Um den Batteriepack 6 in der in Fig. 1 dargestellten hinteren Verriegelungsposition festzuhalten, umfasst die in das Elektrowerkzeug 4 integrierte Verriegelungsvorrichtung 2 einen zweiarmigen Hebel 18, dessen einer Hebelarm einen Riegel 20 bildet und in der hinteren Verriegelungsposition in eine Ausnehmung 22 in der Oberseite der Führungsschiene 12 eingreift, während sein anderer Hebelarm eine Entriegelungstaste 24 bildet, die über eine äußere Oberfläche des Griffteils 8 des Elektrowerkzeugs 4 übersteht und sich zum Entriegeln des Batteriepacks 6 in der hinteren Verriegelungsposition manuell niederdrücken lässt.To the battery pack 6 in the in Fig. 1 To hold the illustrated rear locking position includes the in the power tool. 4 integrated locking device 2 a two-armed lever 18, one lever arm forms a latch 20 and engages in the rear locking position in a recess 22 in the top of the guide rail 12, while its other lever arm forms an unlocking button 24 which extends over an outer surface of the handle portion 8 of Electric tool 4 protrudes and can be manually depress for unlocking the battery pack 6 in the rear locking position.

Der Riegel 20 ist mit einer hinteren, im Wesentlichen senkrecht zur Einschubrichtung (Pfeil A in Fig. 1) ausgerichteten Anschlagfläche 28 versehen, die in der hinteren Verriegelungsposition gegen eine komplementäre Anschlagfläche 30 der Ausnehmung 22 anliegt und eine Bewegung des Batteriepacks 6 entgegen der Einschubrichtung blockiert. Weiter ist der Riegel 20 mit einer vorderen Auflaufschräge 32 versehen, die einer entsprechenden Auflaufschräge 34 der Ausnehmung 22 gegenüberliegt. An das obere Ende der Auflaufschräge 32 grenzt eine weitere, quer zur Einschubrichtung ausgerichtete Anschlagfläche 26 an, während sich über der Auflaufschräge 34 der Ausnehmung 22 eine entsprechende Anschlagfläche 27 befindet. Die Ausnehmung 22 ist etwas größer als der Riegel 20, so dass dieser innerhalb der Ausnehmung 22 begrenzt verschwenkbar ist.The bolt 20 is connected to a rear, substantially perpendicular to the insertion direction (arrow A in FIG Fig. 1 ) aligned stop surface 28 which abuts in the rear locking position against a complementary stop surface 30 of the recess 22 and blocks movement of the battery pack 6 against the insertion direction. Next, the latch 20 is provided with a front ramp 32 which faces a corresponding ramp 34 of the recess 22. At the upper end of the ramp 32 adjoins another, aligned transversely to the direction of insertion stop surface 26, while above the ramp 34 of the recess 22 is a corresponding stop surface 27. The recess 22 is slightly larger than the bolt 20 so that it is limited pivotable within the recess 22.

Der Hebel 18 weist zwei über entgegengesetzte Längsseitenflächen überstehende Achszapfen 36 auf, die in einer im Griffteil 8 ausgesparten Führungskulisse beweglich gelagert sind. Die Führungskulisse besteht aus zwei gegenüberliegenden Aussparungen 38 im Griffteil, die jeweils einen zur Bewegungsrichtung der Führungsschiene 12 in der Führungsnut 10 parallelen langgestreckten Mittelteil 40 und zwei am vorderen bzw. hinteren Ende des Mittelteils 40 nach oben über diesen überstehende Abschnitte 42 und 44 aufweisen, welche unter einem Winkel von etwa 80 bzw. etwa 100 Grad zur Einschubrichtung ausgerichtet sind.The lever 18 has two over opposite longitudinal side surfaces projecting axle 36, which are movably mounted in a recessed in the handle part 8 guide slot. The guide slot consists of two opposite recesses 38 in the handle portion, each one parallel to the direction of movement of the guide rail 12 in the guide groove 10 elongated central portion 40 and two at the front and rear end of the central portion 40 upwards over these projecting portions 42 and 44, which are aligned at an angle of about 80 and about 100 degrees to the insertion direction.

Weiter umfasst die Verriegelungsvorrichtung 2 eine auf den Hebel 18 einwirkende Schraubendruckfeder 46, die sich mit ihrem vorderen Ende an einer Schulter 48 des Hebels 18 und mit ihrem hinteren Ende im Griffteil 8 abstützt.Further, the locking device 2 comprises a force acting on the lever 18 helical compression spring 46, which is supported with its front end to a shoulder 48 of the lever 18 and with its rear end in the handle part 8.

Im folgenden wird die Funktionsweise der Verriegelungsvorrichtung 2 unter Bezugnahme auf die Figuren 1 bis 6 beschrieben.In the following, the operation of the locking device 2 with reference to the FIGS. 1 to 6 described.

In der in Fig. 1 dargestellten hinteren Verriegelungsposition greift der Riegel 20 in die Ausnehmung 22 in der Führungsschiene 12 des Batteriepacks 6 ein, während sich die beiden Achszapfen 36 des Hebels 18 in den nahezu quer zur Einschubrichtung ausgerichteten hinteren Abschnitten 44 der Führungskulisse 38 befinden, wo sie durch die Kraft der zusammengedrückten Feder 46 gegen eine vordere Begrenzungswand dieser Abschnitte 44 angedrückt werden. Durch den Reibkontakt mit dieser Wand werden die Achszapfen 36 in den Abschnitten 44 festgehalten und damit der Batteriepack 6 in der hinteren Verriegelungsposition in Bezug zum Elektrowerkzeug 4 unbeweglich verriegelt. Wie bereits ausgeführt, sind dort Anschlusskontakte des Stromspeichers des Batteriepacks 6 und des Stromkreises des Verbrauchers des Elektrowerkzeugs 4 elektrisch miteinander verbunden (nicht dargestellt).In the in Fig. 1 shown locking position engages the latch 20 in the recess 22 in the guide rail 12 of the battery pack 6, while the two stub axles 36 of the lever 18 in the almost transverse to the insertion direction rear portions 44 of the guide slot 38, where they by the force of compressed spring 46 are pressed against a front boundary wall of these sections 44. Due to the frictional contact with this wall, the stub axles 36 are held in the sections 44 and thus the battery pack 6 is locked immovably in the rear locking position with respect to the power tool 4. As already stated, there terminal contacts of the power storage of the battery pack 6 and the circuit of the consumer of the power tool 4 are electrically connected to each other (not shown).

Wenn zur Entnahme des Batteriepacks 6 die Entriegelungstaste 24 in dieser Position manuell niedergedrückt wird, dreht sich der Hebel 18 um eine innerhalb des Riegels 20 liegende Drehachse, wie durch den Pfeil B in Fig. 2 dargestellt. Dabei bewegen sich die beiden Achszapfen 36 des Hebels 18 nach unten in Richtung des Batteriepacks 6, bis sie das hintere Ende der Mittelteile 40 der Führungskulisse 38 erreichen und der gesamte Hebel 18 durch die Kraft der Schraubendruckfeder 46 entgegen der Einschubrichtung entlang des Mittelteils 40 nach vorne verschoben wird, wie durch den Pfeil C in Fig. 3 dargestellt. Nach dem Verschwenken des Hebels 18 liegen sich zudem die beiden Anschlagflächen 26, 27 des Riegels 20 und der Ausnehmung 22 gegenüber, so dass der Batteriepack 6 unter Aufrechterhaltung der Verriegelung mit dem Hebel 18 mit nach vorne bewegt wird, wie durch den Pfeil D in Fig. 3 dargestellt. Während dieser Bewegung bleibt die Entriegelungstaste 24 in ihrer niedergedrückten Stellung, in der sie sich nicht betätigen lässt.If the unlocking button 24 is depressed manually in this position to remove the battery pack 6, the lever 18 rotates about an axis of rotation 20 lying within the bolt, as by the arrow B in Fig. 2 shown. In this case, the two journal 36 of the lever 18 move downward in the direction of the battery pack 6 until they reach the rear end of the middle parts 40 of the guide slot 38 and the entire lever 18 against the insertion direction along the middle part 40 forward by the force of the helical compression spring 46 is shifted as indicated by the arrow C in Fig. 3 shown. After the pivoting of the lever 18 are also the two stop surfaces 26, 27 of the bolt 20 and the recess 22 opposite, so that the battery pack 6 is moved while maintaining the lock with the lever 18 with forward, as indicated by the arrow D in Fig. 3 shown. During this movement, the release button 24 remains in its depressed position in which it can not be operated.

Wenn die Achszapfen 36 das vordere Ende der Mittelteile 40 der Führungskulisse 38 erreichen, werden sie von der Schraubendruckfeder 46 entlang der schrägen vorderen Begrenzungswand der Abschnitte 42 nach oben in diese hinein gedrückt, wie in Fig. 4 dargestellt. In dieser Stellung nehmen der Hebel 18 und der Batteriepack 6 eine definierte vordere Verriegelungsposition ein, in welcher der Batteriepack 6 mit dem Elektrowerkzeug 4 verriegelt ist, jedoch keine elektrische Verbindung zwischen dem Stromspeicher des Batteriepacks 6 und dem Stromkreises des Verbrauchers des Elektrowerkzeugs 4 besteht, da sich deren Anschlusskontakte im Abstand voneinander befinden. In der vorderen Verriegelungsposition steht die Entriegelungstaste 24 wieder über den Griffteil 8 über, so dass sie sich zur vollständigen Entriegelung des Batteriepacks 6 niederdrücken lässt.When the stub axles 36 reach the front end of the middle portions 40 of the guide slot 38, they are urged upwardly by the helical compression spring 46 along the inclined front boundary wall of the sections 42, as in FIG Fig. 4 shown. In this position, the lever 18 and the battery pack 6 take a defined front locking position in which the battery pack 6 is locked to the power tool 4, but no electrical connection between the power storage of the battery pack 6 and the circuit of the consumer of the power tool 4 is their connection contacts are at a distance from each other. In the front locking position, the unlocking button 24 again protrudes beyond the grip part 8, so that it can be pressed down to completely unlock the battery pack 6.

Bei diesem Vorgang dreht sich der Hebel 18 um die in den Abschnitten 42 befindlichen Achszapfen 36, wie durch den Pfeil E in Fig. 5 angezeigt, wobei der Riegel 20 aus dem Eingriff mit der Ausnehmung 22 heraus bewegt wird. Dadurch wird der Batteriepack 6 freigegeben, so dass er sich entgegen der Einschubrichtung vollständig aus der Führung 10 des Elektrowerkzeugs 4 heraus bewegen lässt, wie durch den Pfeil F in Fig. 6 dargestellt.In this process, the lever 18 rotates about the located in the sections 42 journals 36, as indicated by the arrow E in Fig. 5 indicated, wherein the latch 20 is moved out of engagement with the recess 22 out. As a result, the battery pack 6 is released, so that it can be moved completely out of the guide 10 of the power tool 4, contrary to the insertion direction, as indicated by the arrow F in FIG Fig. 6 shown.

Beim Einschieben eines neuen Batteriepacks 6 in die Führungsnut 10 des Elektrowerkzeugs 4 ist der Bewegungsablauf im Wesentlichen umgekehrt. Sofern sich der Riegel 20 beim Einschieben des Batteriepacks 6 nicht bereits in der in Fig. 6 dargestellten Stellung befindet, wird er in diese Stellung verschwenkt, wenn die Oberkante der Anschlagfläche 14 des Batteriepacks 6 mit dem Riegel 20 in Berührung kommt und über dessen Auflaufschräge 32 gleitet. Wenn sich beim weiteren Einschieben des Batteriepacks 6 die Ausnehmung 22 unter dem Riegel 20 hindurch bewegt, dreht sich dieser um die in den Abschnitten 42 der Führungskulisse 38 befindlichen Achszapfen 36, wobei der Batteriepack 6 in der in Fig. 4 dargestellten vorderen Verriegelungsposition ohne die Herstellung einer elektrischen Verbindung mit dem Elektrowerkzeug 4 verriegelt wird. Anschließend wird der Riegel 20 etwas verschwenkt, bis seine Anschlagfläche 26 mit der Anschlagfläche 27 der Ausnehmung 22 in Berührung tritt und sich die Achszapfen 36 aus den Abschnitten 42 in die Mittelteile 40 der Führungskulisse 38 bewegen, wie in Fig. 3 dargestellt. Danach kann der Batteriepack 6 entgegen der Kraft der Feder 46 in die hintere Verriegelungsposition geschoben werden, in der sich die Achszapfen in die Abschnitte 44 der Führungskulisse 38 bewegen und eine elektrische Verbindung zwischen dem Stromspeicher des Batteriepacks 6 und dem Stromkreises des Verbrauchers des Elektrowerkzeugs 4 hergestellt wird.When inserting a new battery pack 6 in the guide groove 10 of the power tool 4, the movement is substantially reversed. If the latch 20 when inserting the battery pack 6 is not already in the in Fig. 6 shown position, it is pivoted to this position when the upper edge of the stop surface 14 of the battery pack 6 comes into contact with the latch 20 and slides over the ramp 32. If, as the battery pack 6 continues to slide in, the recess 22 moves under the bolt 20, this rotates about the axle stubs 36 located in the sections 42 of the guide slot 38, the battery pack 6 being in the position shown in FIG Fig. 4 illustrated front locking position is locked without the establishment of an electrical connection with the power tool 4. Subsequently, the latch 20 is slightly pivoted until its abutment surface 26 contacts the abutment surface 27 of the recess 22 and the stub axles 36 move from the sections 42 into the middle parts 40 of the guide slot 38, as in FIG Fig. 3 shown. Thereafter, the battery pack 6 can be pushed against the force of the spring 46 in the rear locking position in which the axle journals move into the sections 44 of the guide slot 38 and an electrical connection between the power storage of the battery pack 6 and the circuit of the consumer of the power tool 4 is produced.
