Offenbarung der ErfindungDisclosure of the invention

Die Erfindung geht aus von einem Handwerkzeugmodul mit einer Verschaltungsvorrichtung, die eine Schnittstelle aufweist.The invention is based on a hand tool module with an interconnection device that has an interface.

Es wird vorgeschlagen, dass die Verschaltungsvorrichtung neben der Schnittstelle zumindest eine Zusatzschnittstelle aufweist, die dazu vorgesehen ist, zumindest Energie zumindest mit einem weiteren Handwerkzeugmodul bidirektional auszutauschen. Unter einem "Handwerkzeugmodul" soll insbesondere ein Modul verstanden werden, das dazu vorgesehen ist, direkt und/oder indirekt, in zumindest einem Betriebszustand mechanisch fest mit dem Handwerkzeug verbunden zu werden. Insbesondere ist das Handwerkzeugmodul dazu vorgesehen, das Handwerkzeug mit Energie zu versorgen und/oder mit zumindest einer Funktion nachzurüsten. Insbesondere soll unter einer "Schnittstelle" eine Vorrichtung verstanden werden, die dazu vorgesehen ist, eine elektrische und insbesondere eine mechanische Verbindung mit einem dritten Gerät und/oder vorteilhaft mit dem Handwerkzeug direkt oder indirekt herzustellen. Unter der Wendung "neben der Schnittstelle eine Zusatzschnittstelle aufweisen" soll insbesondere verstanden werden, dass die Verschaltungsvorrichtung eine Schnittstelle und eine insbesondere räumlich getrennte Zusatzschnittstelle aufweist. Vorteilhaft sind die Schnittstelle und die Zusatzschnittstelle mit unterschiedlichen Geräten verbindbar. Unter "einem weiteren Handwerkzeugmodul" soll insbesondere ein zweites, vorteilhaft erfindungsgemäßes Handwerkzeugmodul verstanden werden. Unter "Energie bidirektional austauschen" soll insbesondere verstanden werden, dass die Zusatzschnittstelle dazu vorgesehen ist, Energie an ein drittes Gerät, insbesondere an ein Handwerkzeugmodul, abzugeben und von dem dritten Gerät zu empfangen. Unter dem Begriff "Handwerkzeug" sollen sämtliche, dem Fachmann als sinnvoll erscheinenden Handwerkzeuge, die insbesondere dazu vorgesehen sind, mit einer Akkueinheit betrieben zu werden, wie insbesondere Bohrmaschinen, Bohrhämmer, Sägen, Hobel, Schrauber, Fräsen, Schleifer, Multifunktionswerkzeuge, Messgeräte und/oder insbesondere Bohrschrauber, verstanden werden. Vorteilhaft ist das Handwerkzeug als eine Handwerkzeugmaschine ausgebildet. Unter "vorgesehen" soll insbesondere speziell ausgestattet, ausgelegt und/oder programmiert verstanden werden. Durch die erfindungsgemäße Ausgestaltung des Handwerkzeugmoduls kann erreicht werden, dass an einem mit dem Handwerkzeug verbundenen Handwerkzeugmodul vorteilhaft ein weiteres Handwerkzeugmodul angebracht werden kann. Dabei kann das weitere Handwerkzeugmodul durch die bidirektionale Zusatzschnittstelle vorteilhaft einen Energieverbraucher, eine Energiequelle und/oder einen Energiespeicher aufweisen. Dadurch kann das Handwerkzeugmodul besonders flexibel das Handwerkzeug um verschiedene Funktionen ergänzen.It is proposed that in addition to the interface, the interconnection device has at least one additional interface, which is provided for bidirectionally exchanging at least energy with at least one further hand tool module. A “hand tool module” is to be understood in particular as a module which is intended to be mechanically and permanently connected to the hand tool directly and / or indirectly in at least one operating state. In particular, the hand tool module is provided to supply the hand tool with energy and / or to retrofit it with at least one function. In particular, an “interface” is to be understood to mean a device which is intended to establish an electrical and in particular a mechanical connection with a third device and / or advantageously with the hand tool directly or indirectly. Under the phrase "have an additional interface next to the interface" can be understood in particular that the interconnection device has an interface and an additional interface that is spatially separate in particular. The interface and the additional interface can advantageously be connected to different devices. "Another hand tool module" should in particular be understood to mean a second hand tool module which is advantageous according to the invention. “Exchanging energy bidirectionally” is to be understood in particular to mean that the additional interface is intended to deliver energy to a third device, in particular to a hand tool module, and to receive it from the third device. The term “hand tool” is intended to mean all hand tools which appear to be useful to a person skilled in the art and which are intended in particular to be operated with a rechargeable battery unit, such as, in particular, drilling machines, rotary hammers, saws, planes, screwdrivers, milling cutters, grinders, multi-function tools, measuring devices and / or in particular drill drivers. The hand tool is advantageously designed as a hand tool. “Provided” is to be understood to mean in particular specially equipped, designed and / or programmed. The configuration of the hand tool module according to the invention makes it possible to advantageously attach a further hand tool module to a hand tool module connected to the hand tool. The additional hand tool module can advantageously have an energy consumer, an energy source and / or an energy store due to the bidirectional additional interface. As a result, the hand tool module can supplement the hand tool with various functions in a particularly flexible manner.

In einer weiteren Ausgestaltung wird vorgeschlagen, dass die Schnittstelle und die Zusatzschnittstelle auf zwei unterschiedlichen Seiten, insbesondere auf unterschiedlichen Seiten eines Grundkörpers, wie eines Gehäuses des Handwerkzeugmoduls, angeordnet sind, wodurch das Handwerkzeugmodul und zumindest ein weiteres Modul vorteilhaft gestapelt werden können. Vorteilhaft sind die Schnittstelle und die Zusatzschnittstelle auf gegenüberliegenden Seiten eines Gehäuses des Handwerkzeugmoduls angeordnet.In a further embodiment, it is proposed that the interface and the additional interface be arranged on two different sides, in particular on different sides of a base body, such as a housing of the hand tool module, whereby the hand tool module and at least one further module can advantageously be stacked. The interface and the additional interface are advantageously arranged on opposite sides of a housing of the hand tool module.

Des Weiteren wird vorgeschlagen, dass zumindest die Schnittstelle dazu vorgesehen ist, zumindest eine lösbare mechanische Verbindung zumindest zu einem weiteren Handwerkzeugmodul und/oder dem Handwerkzeug herzustellen. Unter einer "lösbaren mechanischen Verbindung" soll insbesondere eine Verbindung verstanden werden, die von einem Bediener insbesondere werkzeuglos lösbar ist. Vorteilhaft ist die Verbindung als eine Rastverbindung, als eine formschlüssige Einschubverbindung, als eine, dem Fachmann als sinnvoll erscheinende Verbindung und/oder vorteilhaft als eine Klettverbindung mit leitenden Bereichen ausgebildet. Durch die lösbare mechanische Verbindung zu einem weiteren Handwerkzeugmodul und/oder dem Handwerkzeug kann vorteilhaft erreicht werden, dass das Handwerkzeugmodul und zumindest ein weiteres Modul vorteilhaft besonders komfortabel und konstruktiv einfach kombiniert werden können. Vorzugsweise sind die Schnittstelle und die Zusatzschnittstelle zueinander komplementär ausgebildet. Das heißt insbesondere, dass die Schnittstelle und die Zusatzschnittstelle zwei zueinander passende Gegenstücke eines Kontaktmittelsystems, insbesondere eine Steckverbindung, bilden. Alternativ weist vorzugsweise ein Handwerkzeugmodul mit einem Energiespeicher eine Schnittstelle auf, die zu der Zusatzschnittstelle unkomplementär ist.

Vorzugsweise ist das Handwerkzeugmodul mit dem Energiespeicher als ein herkömmlicher Handwerkzeugakku mit einer erfindungsgemäßen Zusatzschnittstelle ausgebildet. Dadurch kann vorteilhaft ein handelsübliches Handwerkzeug zu einem erfindungsgemäßen System aufgerüstet werden.Furthermore, it is proposed that at least the interface be provided for establishing at least one detachable mechanical connection at least to a further hand tool module and / or the hand tool. A "releasable mechanical connection" is intended in particular to be a connection be understood, which can be solved by an operator in particular without tools.
