Description

„Netzbetreibbares Akku-Ladegerät, Ladesystem und Handwerkzeugmaschine" "Network Operated Battery Charger, Charging System and Hand Tool"
Die vorliegende Erfindung betrifft ein netzbetreibbares Akku-Ladegerät mit einem Ladergehäuse, das eine zum Anschluss eines Haupt-Werkzeugakkus einer Handwerkzeugmaschine ausgebildete Hauptladeschnittstelle aufweist, die an einer Anschlussseite des Ladergehäuses angeordnet ist. Die vorliegende Erfindung betrifft ebenfalls ein Ladesystem mit einem netzbetreibbaren Akku-Ladegerät und einem Haupt-Werkzeugakku. Des Weiteren betrifft die vorliegende Erfindung eine Handwerkzeugmaschine, insbesondere Bohrhammer oder Kombihammer, mit einem Werkzeuggehäuse in dessen Akku-Aufnahmebucht eine zum Anschluss eines Haupt-Werkzeugakkus ausgebildete Hauptversorgungsschnittstelle angeordnet ist. The present invention relates to a mains-operated battery charger with a charger housing, which has a main charging interface designed to connect a main tool battery of a handheld power tool, which is arranged on a connection side of the charger housing. The present invention also relates to a charging system with a mains-powered battery charger and a main tool battery. Furthermore, the present invention relates to a hand tool, in particular hammer drill or combination hammer, with a tool housing in the battery receiving bay a trained for connection of a main tool battery main supply interface is arranged.
Es ist Aufgabe der vorliegenden Erfindung, ein netzbetreibbares Akku-Ladegerät, ein Ladesystem sowie eine Handwerkzeugmaschine anzugeben, die vielseitig einsetzbar sind. Bezüglich des Akku-Ladegeräts wird die Aufgabe dadurch gelöst, dass das Akku-Ladegerät wenigstens eine auf der Anschlussseite des Ladergehäuses angeordnete Nebenladeschnittstelle aufweist, die derart zwischen einer Ladestellung und einer Ruhestellung verlagerbar ausgebildet ist, dass ein Neben-Werkzeugakku an der Nebenladeschnittstelle anschließbar ist, wenn sich die Nebenladeschnittstelle in einer Ladestellung befindet.  It is an object of the present invention to provide a network-operated battery charger, a charging system and a hand tool that are versatile. With respect to the battery charger, the object is achieved in that the battery charger has at least one arranged on the connection side of the charger housing auxiliary charging interface, which is designed such displaceable between a loading position and a rest position that a secondary tool battery can be connected to the auxiliary charging interface, when the auxiliary charging interface is in a loading position.
Haupt-Werkzeugakku und Neben-Werkzeugakku können verschiedenen Typs sein, insbesondere können Haupt-Werkzeugakku und Neben-Werkzeugakku zum Betrieb von Handwerkzeugmaschinen verschiedenen Typs ausgebildet und/oder bestimmt sein.  Main tool battery and sub-tool battery can be of various types, in particular main tool battery and sub-tool battery can be designed and / or determined for operating hand tool machines of various types.
Die Erfindung schließt die Erkenntnis ein, dass Haupt-Werkzeugakkus und Neben- Werkzeugakkus, insbesondere, wenn sie verschiedenen Typs sind, bisher nicht über ein und dasselbe Akku-Ladegerät geladen werden konnten. So ist es beispielsweise mit Akku- Ladegeräten des Standes der Technik unmöglich, sowohl einen Haupt-Werkzeugakku einer neuen Generation als auch einen Neben-Werkzeugakku einer älteren Generation an ein und derselben Anschlussseite des Akku-Ladegeräts zu laden, da diese typischerweise mechanisch verschieden kodiert sind bzw. mechanisch unterschiedliche Ausführungen aufweisen, die inkompatible zueinander sind. Durch das erfindungsgemäße netzbetreibbare Akku-Ladegerät kann nun vorteilhafterweise an der Nebenladeschnittstelle ein Neben-Werkzeugakku geladen werden, wobei die Nebenladeschnittstelle zwischen der Ladestellung und der Ruhestellung verlagerbar ist. Dies hat den Vorteil, dass an ein und derselben Anschlussseite des Ladergehäuses Akkus verschiedenen Typs geladen werden können, wodurch das Akku- Ladegerät vielseitig einsetzbar ist. The invention includes the recognition that main tool rechargeable batteries and sub-tool rechargeable batteries, especially if of different types, could not previously be charged via one and the same rechargeable battery charger. For example, with battery chargers of the prior art, it is impossible to load both a new-generation main tool battery and an older-generation sub-tool battery on one and the same terminal side of the battery charger because they are typically mechanically differently coded or mechanically different versions that are incompatible with each other. By means of the network-operated battery charger according to the invention, an auxiliary tool battery can now be advantageously charged at the auxiliary charging interface be, with the sub-charging interface between the loading position and the rest position is displaced. This has the advantage that on one and the same connection side of the charger housing different types of batteries can be charged, making the battery charger is versatile.
In einer bevorzugten Ausgestaltung ist die Hauptladeschnittstelle mechanisch gegen den Anschluss des Haupt-Werkzeugakkus gesperrt, wenn sich die Nebenladeschnittstelle in der Ladestellung befindet. Somit kann bereits wirksam ein Laden eines nicht zum Anschluss an die Nebenladeschnittstelle geeigneten Akkutyps verhindert werden, wodurch das Akku-Ladegerät besonders sicher betreibbar ist. In a preferred embodiment, the main charging interface is mechanically locked against the connection of the main tool battery when the sub-charging interface is in the loading position. Thus, charging of a battery type not suitable for connection to the auxiliary charging interface can be effectively prevented already, whereby the battery charger can be operated particularly safely.
Alternativ oder zusätzlich kann die Hauptladeschnittstelle mechanisch zum Anschluss des Werkzeugakkus freigegeben sein, wenn sich die Nebenladeschnittstelle in der Ruhestellung befindet. Bevorzugt ist die Nebenladeschnittstelle mechanisch gegen den Anschluss des Neben-Werkzeugakkus gesperrt, wenn sich die Nebenladeschnittstelle in der Ruhestellung befindet. Mit anderen Worten ist das netzbetreibbare Akku-Ladegerät bevorzugt derart ausgestaltet, dass an der Anschlussseite des Ladergehäuses entweder nur ein Haupt- Werkzeugakku oder aber ein Neben-Werkzeugakku anschließbar und/oder aufladbar ist. Alternatively or additionally, the main charging interface can be mechanically released for connection of the tool battery when the auxiliary charging interface is in the rest position. The auxiliary charging interface is preferably mechanically locked against the connection of the auxiliary tool battery when the auxiliary charging interface is in the rest position. In other words, the grid-operable battery charger is preferably designed such that either only a main tool battery or a secondary tool battery can be connected and / or charged on the connection side of the charger housing.
In einer besonders bevorzugten Ausgestaltung ist die Hauptladeschnittstelle als Ladebuchse ausgebildet (weibliche Ausführung). Die Nebenladeschnittstelle kann als zwischen der Ladestellung und der Ruhestellung verschiebbares Schwert ausgebildet sein, welches in der Ladestellung von der Anschlussseite des Ladergehäuses abragt (männliche Ausführung). Bevorzugt ist die als verschiebbares Schwert ausgebildete Nebenladestelle in ihrer Ruhestellung im Wesentlichen flächenbündig mit der Anschlussseite des Ladergehäuses oder jedenfalls nicht von diesem abragend. Bevorzugt weist das Akku-Ladegerät eine Ladeelektronik auf, die innerhalb des Ladergehäuses angeordnet und ausgebildet ist, den über den Hauptladeschnittstelle anzuschließenden Haupt-Werkzeugakku mit einer Haupt- Ladekonfiguration zu laden.  In a particularly preferred embodiment, the main charging interface is designed as a charging socket (female version). The auxiliary charging interface can be designed as a sliding between the loading position and the rest position sword, which protrudes in the loading position of the connection side of the charger housing (male version). Preferably, the secondary charging station designed as a displaceable blade is in its rest position essentially flush with the connection side of the charger housing or at least not protruding from it. Preferably, the battery charger to a charging electronics, which is disposed within the charger housing and is designed to load the to be connected via the main charging interface main tool battery with a main charging configuration.
Die Ladeelektronik kann ebenfalls ausgebildet sein, den über die Nebenladeschnittstelle anzuschließenden Neben-Werkzeugakku mit einer Neben-Ladekonfiguration zu laden. Eine jeweilige Ladekonfiguration weist bevorzugt eine vorbestimmte Stromstärke, eine maximale Ladungsmenge und/oder weitere Ladeparameter auf. So kann die Ladeelektronik beispielsweise dafür eingerichtet sein, einen Haupt-Werkzeugakku mit einer Nennspannung von 36 Volt zu laden und/oder einen Neben-Werkzeugakku mit einer Nennspannung von 14 Volt oder 22 Volt zu laden. Andere Spannungskonfigurationen sind möglich. The charging electronics can also be designed to charge the secondary tool battery to be connected via the auxiliary charging interface with a secondary charging configuration. A respective charging configuration preferably has a predetermined current intensity, a maximum charge quantity and / or further charging parameters. For example, the charging electronics may be configured to accept a main tool battery with a nominal voltage of 36 volts Charge and / or a sub-tool battery with a rated voltage of 14 volts or 22 volts to load. Other voltage configurations are possible.
Bevorzugt ist die Nebenladeschnittstelle elektrisch mit der gleichen Elektronik wie die Hauptladeschnittstelle verbunden. Somit ergibt sich ein besonders einfacher und günstiger Aufbau des Akku-Ladegeräts.  Preferably, the sub-charging interface is electrically connected to the same electronics as the main charging interface. This results in a particularly simple and inexpensive construction of the battery charger.
In einer besonders bevorzugten Ausgestaltung weist das Akku-Ladegerät wenigstens einen Sensor auf, der ausgebildet und angeordnet ist zu sensieren, ob die Nebenladeschnittstelle in der Ladestellung oder der Ruhestellung befindlich ist. Der Sensor kann beispielsweise ein optischer oder mechanischer Sensor sein, der bevorzugt in der Nähe der Anschlussseite des Ladergehäuses angeordnet ist. Mehrere Sensoren können vorgesehen sein.  In a particularly preferred embodiment, the battery charger has at least one sensor which is designed and arranged to sense whether the auxiliary charging interface is located in the charging position or the rest position. The sensor may be, for example, an optical or mechanical sensor, which is preferably arranged in the vicinity of the connection side of the charger housing. Several sensors can be provided.
Im Sinne einer erhöhten Bediensicherheit, aber auch eines erhöhten Bedienkomforts, hat es sich als vorteilhaft herausgestellt, wenn die Ladeelektronik ausgebildet ist, die Ladekonfigurationen in Abhängigkeit eines Sensorwertes des Sensors umzuschalten. Die Nebenladeschnittstelle kann beispielsweise ausgebildet sein, mittels eines manuell betätigbaren Schiebers zwischen der Ladestellung und der Ruhestellung verschiebbar zu sein. Der Sensor kann beispielsweise mechanisch an den Schieber angekoppelt sein, sodass eine für den Haupt- Werkzeugakku bestimmte Ladekonfiguration aktiviert wird, wenn die Nebenladeschnittstelle in der Ruhestellung ist. Andererseits kann beispielsweise eine für die Ladung des Neben- Werkzeugakkus bestimmte Ladekonfiguration aktiviert sein, wenn sich die Nebenladeschnittstelle, sensiert durch den Sensor, in der Ladestellung befindet.  In terms of increased operating safety, but also an increased ease of use, it has been found to be advantageous if the charging electronics is designed to switch the charging configurations as a function of a sensor value of the sensor. The auxiliary charging interface can be designed, for example, to be displaceable by means of a manually operable slide between the loading position and the rest position. For example, the sensor may be mechanically coupled to the slider so that a charge configuration for the main tool battery is activated when the slave charger interface is in the rest position. On the other hand, for example, a charging configuration intended for charging the auxiliary tool battery may be activated when the auxiliary charging interface, sensed by the sensor, is in the charging position.
Bevorzugt sind die zur Aufnahme des Haupt-Werkzeugakkus ausgebildete Hauptladeschnittstelle und die mit einem Neben-Werkzeugakku verbindbare Nebenladeschnittstelle mechanisch verschieden voneinander kodiert, wobei Haupt- Werkzeugakku und Neben-Werkzeugakku bevorzugt verschiedenen Typs sind.  Preferably, the main charging interface formed for receiving the main tool battery and the auxiliary charging interface which can be connected to a secondary tool battery are mechanically coded differently from one another, the main tool battery and secondary tool battery preferably being of different types.
Bevorzugt weist der Haupt-Werkzeugakku eine zur Hauptladeschnittstelle korrespondierende Hauptakkuschnittstelle auf. Des Weiteren bevorzugt weist der Neben-Werkzeugakku eine zur Nebenladeschnittstelle des Akku-Ladegeräts korrespondierende Nebenakkuschnittstelle auf. Das Akku-Ladegerät kann eine, zwei, oder mehrere Nebenladeschnittstellen aufweisen. Bevorzugt weist das Akku-Ladegerät genau eine Nebenladeschnittstelle auf. Das Akku- Ladegerät kann genau zwei Nebenladeschnittstellen aufweisen. Preferably, the main tool battery has a Hauptakkuschnittstelle corresponding to the main load interface. Furthermore, the auxiliary tool battery preferably has a secondary battery interface corresponding to the auxiliary charging interface of the battery charger. The battery charger may have one, two, or more auxiliary charging interfaces. The battery charger preferably has exactly one auxiliary charging interface. The battery charger can have exactly two auxiliary charging interfaces.
Bezüglich des Ladesystems wird die Aufgabe gelöst durch ein vorbeschriebenes netzbetreibbares Akku-Ladegerät und wenigstens einem Haupt-Werkzeugakku zu dessen Anschluss die Hauptladeschnittstelle des netzbetreibbaren Akku-Ladegeräts ausgebildet ist und /oder mit wenigstens einem Neben-Werkzeugakku zu dessen Anschluss die Nebenladeschnittstelle ausgebildet ist. With respect to the charging system, the object is achieved by a network-operated rechargeable battery charger described above and at least one main tool battery for the same Connection, the main charging interface of the network-operated battery charger is formed and / or with at least one auxiliary tool battery to its connection, the auxiliary charging interface is formed.
Bezüglich der Handwerkzeugmaschine wird die Aufgabe dadurch gelöst, dass in der Aufnahmebucht eine zum bedarfsweisen Anschließen eines Neben-Werkzeugakkus ausgebildete Nebenversorgungsschnittstelle angeordnet ist, die derart zwischen einer Versorgungsstellung und einer Ruhestellung verlagerbar ausgebildet ist, dass der Neben- Werkzeugakku an der Nebenversorgungsschnittstelle anschließbar ist, wenn sich die Nebenversorgungsschnittstelle in der Versorgungsstellung befindet. Die erfindungsgemäße Handwerkzeugmaschine kann in entsprechender Weise zu dem vorbeschriebenen Akku- Ladegerät weitergebildet sein. Beispielsweise ist die Nebenversorgungsschnittstelle bevorzugt als Ladebuchse ausgebildet, sodass eine Nebenladeschnittstelle des Akku-Ladegeräts, die als verschiebbares Schwert ausgebildet ist, in diese Ladebuchse einführbar ist.

Fig. 1 zeigt auf seiner rechten Seite ein netzbetreibbares Akku-Ladegerät 100 gemäß des Standes der Technik. Das Akku-Ladegerät 100 weist ein Ladergehäuse 90 auf, dass eine zum Anschluss eines auf der linken Seite gezeigten Haupt-Werkzeugakkus 10 ausgebildete Hauptladeschnittstelle 1 1 aufweist. Im dargestellten Ausführungsbeispiel ist die Hauptladeschnittstelle 1 1 in Form von drei Ladebuchsen ausgebildet, die an einer Anschlussseite 95 des Ladergehäuses angeordnet sind.  Fig. 1 shows on its right side a mains-powered battery charger 100 according to the prior art. The battery charger 100 has a charger housing 90 that has a main charging interface 11 formed for connecting a main tool battery 10 shown on the left side. In the illustrated embodiment, the main charging interface 1 1 is in the form of three charging sockets, which are arranged on a connection side 95 of the supercharger housing.
Der Haupt-Werkzeugakku 10 auf der linken Seite der Fig. 1 weist eine Hauptakkuschnittstelle 1 1 ' auf, die zur Hauptladeschnittstelle 11 des Akku-Ladegeräts 100 korrespondiert und im vorliegenden Beispiel durch drei starr von einer Oberfläche des Haupt-Werkzeugakkus 10 abragende Schwerter ausgebildet ist. Zum Anschließen des Haupt-Werkzeugakkus 10 an das Akku-Ladegerät 100 des Standes der Technik wird die Hauptakkuschnittstelle 1 1 ' in die korrespondierende Hauptladeschnittstelle 1 1 des Akku-Ladegeräts eingeschoben.  The main tool battery 10 on the left side of FIG. 1 has a Hauptakkuschnittstelle 1 1 ', which corresponds to the main charging interface 11 of the battery charger 100 and is formed in the present example by three rigid protruding from a surface of the main tool battery 10 swords , To connect the main tool battery 10 to the battery charger 100 of the prior art, the Hauptakkuschnittstelle 1 1 'is inserted into the corresponding Hauptladeschnittstelle 1 1 of the battery charger.
Ein erfindungsgemäßes Akku-Ladegerät 100 in Fig. 2 weist zusätzlich zu der Hauptladeschnittstelle 1 1 , die an der Anschlussseite 95 des Ladergehäuses 90 in Form von drei Ladebuchsen bereitgestellt ist, eine Nebenladeschnittstelle 21 auf. Diese Nebenladeschnittstelle 21 ist ebenfalls an der Anschlussseite 95 des Ladergehäuses angeordnet. Im dargestellten Ausführungsbeispiel ist die Nebenladeschnittstelle 21 durch drei verschiebbare Schwerter bereitgestellt. Die Nebenladeschnittstelle 21 in Form der drei Schwerter ist zwischen einer Ladestellung N und einer Ruhestellung N' verlagerbar, genauer gesagt verschiebbar ausgebildet. In Fig. 2 ist die Ruhestellung N' der Nebenladeschnittstelle dargestellt, in der die drei Schwerter im Wesentlichen flächenbündig zur Anschlussseite 95 des Ladergehäuses 90 befindlich ist. Bezüglich der Ladestellung N der Nebenladeschnittstelle 21 sei auf Fig. 4 verwiesen.  An inventive battery charger 100 in FIG. 2 has a secondary charging interface 21 in addition to the main charging interface 11, which is provided on the connection side 95 of the charger housing 90 in the form of three charging sockets. This auxiliary charging interface 21 is likewise arranged on the connection side 95 of the charger housing. In the illustrated embodiment, the sub-loading interface 21 is provided by three sliding swords. The auxiliary charging interface 21 in the form of the three swords is displaceable between a loading position N and a rest position N ', more precisely designed to be displaceable. FIG. 2 shows the rest position N 'of the auxiliary charging interface, in which the three swords are located essentially flush with the connection side 95 of the charger housing 90. With regard to the loading position N of the auxiliary charging interface 21, reference is made to FIG. 4.
Wie ebenfalls aus Fig. 2 ersichtlich ist, weist das Akku-Ladegerät 100 eine Ladeelektronik 70 auf, die innerhalb des Ladergehäuses angeordnet ist. Die Ladeelektronik 70 ist über jeweilige Verbindungskabel 71 sowohl mit der Hauptladeschnittstelle 1 1 als auch der Nebenladeschnittstelle 21 verbunden. As can also be seen from FIG. 2, the battery charger 100 has a charging electronics 70, which is arranged inside the charger housing. The charging electronics 70 is connected via respective connecting cables 71 both to the main charging interface 1 1 and the auxiliary charging interface 21.
Im vorliegenden Ausführungsbeispiel weist das Akku-Ladegerät 100 drei Sensoren 73 auf, die ausgebildet und angeordnet sind zu sensieren, ob die Nebenladeschnittstelle 21 in Form der drei ausschiebbaren Schwerter in der Ladestellung N oder der Ruhestellung N' befindlich ist. In der Darstellung der Fig. 2 ist die Nebenladeschnittstelle in der Ruhestellung N' befindlich, genauer gesagt sind die drei verschiebbaren Schwerter innerhalb eines Volumens 90 angeordnet, sodass diese nicht von der Anschlussseite 95 abragen. Dies ist durch die gestrichelte Darstellung der Nebenladeschnittstelle 21 angedeutet. Im Gegensatz dazu ist die Hauptladeschnittstelle 1 1 in Form der drei Ladebuchsen nicht verschiebbar im Ladergehäuse 90 beziehungsweise an dessen Anschlussseite 95 angeordnet, was durch die Strichpunktlinierung symbolisiert ist. In the present embodiment, the battery charger 100 has three sensors 73, which are designed and arranged to sense whether the auxiliary charging interface 21 is located in the form of the three extendable swords in the loading position N or the rest position N '. In the illustration of FIG. 2, the auxiliary charging interface is in the rest position N ', more precisely, the three displaceable swords are arranged within a volume 90 so that they do not protrude from the connection side 95. This is indicated by the dashed representation of the auxiliary charging interface 21. In contrast, the main charging interface 1 1 in the form of three charging sockets is not slidably disposed in the charger housing 90 and at its connection side 95, which is symbolized by the Strichpunktlinierung.
In Fig. 3 ist dargestellt, wie ein Haupt-Werkzeugakku 10 entlang eines Bewegungspfades P an dem Akku-Ladegerät 100 angeschlossen wird. Dadurch, dass die Nebenladeschnittstelle 21 in der Ruhestellung N' befindlich ist, ist die Anschlussseite 95 zum Anschluss des Haupt- Werkzeugakkus 10 freigegeben. Mit anderen Worten kann dadurch, dass die als drei Schwerter ausgebildete Nebenladeschnittstelle 21 nicht von der Anschlussseite 95 des Ladergehäuses 90 abragt, der Haupt-Werkzeugakku 10 mit seinen als drei Schwerter ausgebildeten Hauptakkuschnittstelle 1 1 ' in die korrespondierenden und als drei Ladebuchsen ausgebildete Hauptladeschnittstelle 1 1 eingeschoben werden.  FIG. 3 shows how a main tool battery 10 is connected along a movement path P to the battery charger 100. Characterized in that the auxiliary charging interface 21 is located in the rest position N ', the connection side 95 is released for connection of the main tool battery 10. In other words, as a result of the fact that the auxiliary charging interface 21 designed as three swords does not project from the connection side 95 of the charger housing 90, the main tool battery 10 with its main battery interface 1 1 'designed as three swords enters the corresponding main charging interface 11 formed as three charging sockets be inserted.
Fig. 4 zeigt nunmehr den Fall, in dem ein Neben-Werkzeugakku 20, der von einem Haupt- Werkzeugakku 10 (vgl. Fig. 3) verschiedentlich mechanisch kodiert ist an dem Akku-Ladegerät 100 angeschlossen wird. Im dargestellten Ausführungsbeispiel weist der Neben-Werkzeugakku 20 eine Nebenakkuschnittstelle 21 ' auf, die wie gezeigt als starr an einer Oberfläche des Neben- Werkzeugakkus 20 angeordnete Buchsen ausgebildet ist. Im vorliegenden Fall sind genau drei Buchsen ausgebildet. 4 now shows the case in which a sub-tool battery 20 which is variously mechanically coded by a main tool battery 10 (see Fig. 3) is connected to the rechargeable battery charger 100. In the illustrated embodiment, the slave tool battery 20 has a slave battery interface 21 ', which as shown is configured as sockets rigidly disposed on a surface of the slave tool battery 20. In the present case exactly three sockets are formed.
Auf der rechten Seite der Fig. 4 ist das Akku-Ladegerät 100 dargestellt, wobei sich die Nebenladeschnittstelle 21 in der Ladestellung N befindet. Wie ersichtlich, ragen die drei verschiebbaren Schwerter, die die Nebenladeschnittstelle 21 des Akku-Ladegeräts 100 bilden, von der Anschlussseite 95 des Ladergehäuses 90 ab. Dadurch ist der Neben-Werkzeugakku 20 mit seiner korrespondierenden Nebenakkuschnittstelle 21 ' an der Nebenladeschnittstelle 21 anschließbar. Gleichermaßen ist dadurch, dass die Nebenladeschnittstelle 21 in Form der drei verschiebbaren Schwerter von der Anschlussseite 95 des Ladergehäuses 90 abragen, die Hauptladeschnittstelle 1 1 mechanisch gegen den Anschluss des Haupt-Werkzeugakkus 10 (vgl. Fig. 3) gesperrt.  On the right side of FIG. 4, the battery charger 100 is shown, wherein the auxiliary charging interface 21 is in the loading position N. As can be seen, the three displaceable swords, which form the auxiliary charging interface 21 of the battery charger 100, protrude from the connection side 95 of the charger housing 90. As a result, the auxiliary tool battery 20 with its corresponding secondary battery interface 21 'can be connected to the auxiliary charging interface 21. Likewise, since the auxiliary charging interface 21 in the form of the three displaceable swords projects from the connection side 95 of the charger housing 90, the main charging interface 11 is mechanically locked against the connection of the main tool battery 10 (see FIG.
Fig. 5 zeigt schematisch eine Schnittdarstellung und Draufsicht auf ein zweites Ausführungsbeispiel eines erfindungsgemäßen Akku-Ladegeräts 100. Das Akku-Ladegerät 100 weist eine Hauptladeschnittstelle 1 1 sowie eine erste Nebenladeschnittstelle 21 und eine zweite Nebenladeschnittstelle 31 auf. Vorliegend sind sowohl die Hauptladeschnittstelle 11 als auch die Nebenladeschnittstelle 21 , 31 zwischen einer Ladestellung N (nicht dargestellt) und einer Ruhestellung N' (dargestellt) verschiebbar. 5 shows a schematic sectional view and a top view of a second exemplary embodiment of a battery charger 100 according to the invention. The battery charger 100 has a main charging interface 11 and a first auxiliary charging interface 21 and a second Sublimation interface 31 on. In the present case, both the main charging interface 11 and the auxiliary charging interface 21, 31 are displaceable between a loading position N (not shown) and a rest position N '(shown).
Wie aus Fig. 6 ersichtlich ist, ist die Hauptladeschnittstelle 1 1 vorliegend als verschiebbare Ladebuchse ausgebildet und in Fig. 6 in Ladestellung N dargestellt. Somit kann ein Haupt- Werkzeugakku 10, der eine als starres Schwert ausgebildete Hauptakkuschnittstelle 1 1 ' aufweist an dem Akku-Ladegerät 100 angeschlossen und dementsprechend geladen werden.  As can be seen from FIG. 6, the main charging interface 11 is in the present case designed as a displaceable charging socket and shown in charging position N in FIG. Thus, a main tool battery 10 having a trained as a rigid sword Hauptakkuschnittstelle 1 1 'connected to the battery charger 100 and loaded accordingly.
In Fig. 7 ist die soeben mit Bezug auf Fig. 6 beschriebene Hauptladeschnittstelle 1 1 in einer Ruhestellung N' dargestellt, das heißt sie ist innerhalb des Ladergehäuses 90 angeordnet beziehungsweise ragt jedenfalls nicht von der Anschlussseite 95 ab. Eine als verschiebbare Ladebuchse ausgebildete erste Nebenladeschnittstelle 21 ist in Fig. 7 in Ladestellung N gezeigt, sodass ein erster Neben-Werkzeugakku 20, der eine erste Nebenakkuschnittstelle 21 ' in Form eines zu der ersten Nebenladeschnittstelle 21 korrespondierenden Schwertes aufweist, an dem Akku-Ladegerät 100 anschließbar ist und geladen werden kann.  In FIG. 7, the main charging interface 1 1 just described with reference to FIG. 6 is shown in a rest position N ', that is to say it is arranged inside the charger housing 90 or in any case does not project from the connection side 95. A first auxiliary charging interface 21 embodied as a displaceable charging socket is shown in charging position N in FIG. 7, so that a first auxiliary tool battery 20, which has a first secondary battery interface 21 'in the form of a sword corresponding to the first auxiliary charging interface 21, on the battery charger 100 is connectable and can be loaded.
Fig. 8 wiederum zeigt das Akku-Ladegerät 100, wobei eine zweite Nebenladeschnittstelle 31 , die im vorliegenden Beispiel als verschiebbares Schwert ausgebildet ist, in Ladestellung N befindlich ist und dementsprechend von der Anschlussseite 95 des Ladergehäuses 90 abragt. Somit ist ein zweiter Neben-Werkzeugakku 30 mit einer zweiten Nebenakkuschnittstelle 31 ' am Akku-Ladegerät 100 anschließbar und ladbar. Gleichermaßen ist dadurch, dass die zweite Nebenladeschnittstelle 31 in Form des Schwerts von der Anschlussseite 95 des Ladergehäuses 95 abragt, ein Anschluss des Haupt-Werkzeugakkus 10 der Fig. 6 oder des ersten Neben- Werkzeugakkus 20 der Fig. 7 am Akku-Ladegerät 100 der Fig. 8 mechanisch gesperrt. 8 again shows the battery charger 100, wherein a second auxiliary charging interface 31, which in the present example is designed as a displaceable blade, is located in the charging position N and accordingly protrudes from the connection side 95 of the charger housing 90. Thus, a second auxiliary tool battery 30 with a second Nebenakkuschnittstelle 31 'on the battery charger 100 can be connected and loaded. Similarly, the fact that the second auxiliary charging interface 31 in the form of the sword protrudes from the connection side 95 of the charger housing 95, a connection of the main tool battery 10 of FIG. 6 or the first auxiliary tool battery 20 of FIG. 7 to the battery charger 100 of Fig. 8 mechanically locked.
Fig. 9 zeigt eine erfindungsgemäße Handwerkzeugmaschine 1000 in Form eines Bohrhammers. Die Handwerkzeugmaschine 1000 weist ein Werkzeuggehäuse 1090 auf, in dessen Akku- Aufnahmebucht 1080 eine zum Anschluss eines Haupt-Werkzeugakkus 10 ausgebildete Hauptversorgungsschnittstelle 101 1 ' in Form dreier Anschlussbuchsen angeordnet ist. Die in Form von drei Anschlussbuchsen bereitgestellte Hauptversorgungsschnittstelle 1011 ' korrespondiert zu einer Hauptakkuschnittstelle 1 1 ', die als vom Haupt-Akku 10 starr abragende drei Schwerter bereitgestellt ist.  9 shows a hand-held power tool 1000 according to the invention in the form of a hammer drill. The hand-held power tool 1000 has a tool housing 1090, in the battery receiving bay 1080 of which a main tooling interface 101 1 'designed to connect a main tool battery 10 is arranged in the form of three connection sockets. The provided in the form of three sockets main supply interface 1011 'corresponds to a Hauptakkuschnittstelle 1 1', which is provided as rigidly projecting from the main battery 10 three swords.
In der Aufnahmebucht 1080 ist eine zum bedarfsweisen Anschließen eines Neben- Werkzeugakkus (nicht gezeigt) ausgebildete Nebenversorgungsschnittstelle 1021 ' angeordnet, die zwischen einer Versorgungsstellung 1000N (gestrichelt dargestellt) und einer Ruhestellung 1000N' (mittels durchgezogener Linie dargestellt) verlagerbar ausgebildet ist. Da sich die Nebenversorgungsschnittstelle 1021 ' wie dargestellt in der Ruhestellung 1000N', das heißt in zurückgezogener Stellung befindet, ist der Haupt-Werkzeugakku 10 an der Hauptversorgungsschnittstelle 1010 anschließbar. Dies wäre nicht der Fall, wenn sich die Nebenversorgungsschnittstelle 1021 ' in Versorgungsstellung 1000N (gestrichelt dargestellt) befände, wodurch die Nebenversorgungsschnittstelle 1021 ' für den Haupt-Werkzeugakku 10 mechanisch gesperrt wäre. In the receiving bay 1080, a secondary supply interface 1021 'designed to connect a secondary tool battery (not shown) as required is arranged between a supply position 1000N (shown in phantom) and a rest position 1000N '(shown by a solid line) is designed to be displaceable. Since the auxiliary supply interface 1021 'as shown in the rest position 1000 N', that is in the retracted position, the main tool battery 10 is connected to the main supply interface 1010. This would not be the case if the auxiliary supply interface 1021 'were in the supply position 1000N (shown in dashed lines), whereby the auxiliary supply interface 1021' for the main tool battery 10 would be mechanically blocked.
