Description
Die vorliegende Erfindung betrifft eine akkubetriebene Handwerkzeugmaschine mit einer Aufnahmebucht, die zur wiederlösbaren Aufnahme einer Akkueinheit ausgebildet ist. Die vorliegende Erfindung betrifft ebenfalls ein System mit einer akkubetriebenen Handwerkzeugmaschine und mit wenigstens einer Akkueinheit, die zur wiederlösbaren Aufnahme in der Aufnahmebucht der Handwerkzeugmaschine ausgebildet ist.The present invention relates to a battery-operated hand-held power tool with a receiving bay which is designed for the releasable receiving of a battery unit. The present invention also relates to a system with a battery-operated hand tool and with at least one battery unit, which is designed for releasable reception in the receiving bay of the hand tool.
Handwerkzeugmaschine der eingangs genannten Art sind grundsätzlich aus dem Stand der Technik bekannt, beispielsweise in Form von Akku-Bohrhämmern oder Akku-Kombihämmern. Diese werden durch eine Akkueinheit, die wiederlösbar in der Aufnahmebucht aufgenommen oder aufzunehmen ist, mit elektrischem Strom versorgt. Die Stromübertragung von der Akkueinheit zur Handwerkzeugmaschine erfolgt dabei typischerweise über eine Akkuschnittstelle, welche an oder in der Aufnahmebucht angeordnet ist.Hand tool of the type mentioned are basically known from the prior art, for example in the form of cordless rotary hammers or cordless combination hammers. These are supplied with electrical current by a rechargeable battery unit which can be detachably received in the receiving bay or is to be received. The power transmission from the rechargeable battery unit to the handheld power tool typically takes place via a rechargeable battery interface, which is arranged on or in the receiving bay.
Es ist Aufgabe der vorliegenden Erfindung eine akkubetriebene Handwerkzeugmaschine bereitzustellen, die die Grundlage für eine erhöhte Betriebssicherheit schafft.It is an object of the present invention to provide a battery-operated hand-held machine tool which creates the basis for increased operational reliability.
Die Erfindung wird dadurch gelöst, dass die Handwerkzeugmaschine einen Sturzrahmen aufweist, der die Akkueinheit, wenn diese in der Aufnahmebucht aufgenommen ist, derart umgibt, dass eine Fallenergie zumindest teilweise von dem Sturzrahmen aufgenommen und so von der Akkueinheit ferngehalten wird.The invention is achieved in that the hand-held power tool has a lintel frame which surrounds the battery unit when it is accommodated in the receiving bay in such a way that a fall energy is at least partially absorbed by the lintel frame and is thus kept away from the battery unit.
Die Erfindung schließt die Erkenntnis ein, dass eine Akkueinheit, die in einer akkubetriebenen Handwerkzeugmaschine des Standes der Technik aufgenommen ist, nur unzureichend gegen unerwünschte Stürze gesichert ist. Im Sturzfall muss die gesamte wirksame Fallenergie von der Akkueinheit selbst aufgenommen werden, was häufig zu einer Zerstörung der Akkueinheit - zumindest aber zu ihrer funktionellen Beeinträchtigung - führt. Aus dem Stand der Technik sind Akkueinheiten bekannt, bei denen ein Gehäuse der Akkueinheit einen Teil der Sturzenergie aufnimmt.The invention includes the finding that a rechargeable battery unit that is accommodated in a battery-operated hand-held power tool of the prior art is only insufficiently secured against undesired falls. In the event of a fall, the entire effective fall energy must be absorbed by the battery unit itself, which often leads to destruction of the battery unit - or at least to its functional impairment. Battery units are known from the prior art, in which a housing of the battery unit absorbs part of the fall energy.
In Abkehr vom Stand der Technik wir eine Handwerkzeugmaschine bereitgestellt, die einen Sturzrahmen aufweist, der die Akkueinheit derart umgibt, dass eine Fallenergie zumindest teilweise von dem Sturzrahmen aufgenommen und so von der Akkueinheit ferngehalten wird. Ein solcher Schutzrahmen schafft die Grundlage für eine erhöhte Betriebssicherheit einer akkubetriebenen Handwerkzeugmaschine.In a departure from the prior art, a hand-held power tool is provided which has a lintel frame which surrounds the battery unit in such a way that a fall energy is at least partially absorbed by the lintel frame and is thus kept away from the battery unit. Such a protective framework creates the basis for increased operational safety of a cordless hand-held power tool.
In einer besonders bevorzugten Ausgestaltung ist der Sturzrahmen ortsfest bezüglich der Aufnahmebucht an der Handwerkzeugmaschine angeordnet.In a particularly preferred embodiment, the lintel frame is arranged in a stationary manner with respect to the receiving bay on the hand power tool.
Es hat sich als vorteilhaft herausgestellt, wenn der Sturzrahmen allseitig von der Akkueinheit beabstandet ist, wenn die Akkueinheit in der Aufnahmebucht aufgenommen ist. Derart kann im Wesentlichen die gesamte Fallenergie durch den Sturzrahmen aufgenommen werden. Alternativ kann der Sturzrahmen an zumindest einer Seite von der Akkueinheit beabstandet sein, was eine Belastung der Akkueinheit durch eine Fallenergie zumindest teilweise reduziert.It has proven to be advantageous if the lintel frame is spaced on all sides from the battery unit when the battery unit is accommodated in the receiving bay. In this way, essentially all of the fall energy can be absorbed by the lintel frame. Alternatively, the lintel frame can be spaced apart from the battery unit on at least one side, which at least partially reduces the load on the battery unit from falling energy.
In einer weiteren bevorzugten Ausgestaltung ist der Sturzrahmen einteilig mit einem Gehäuseabschnitt der Handwerkzeugmaschine ausgebildet ist. Vorzugsweise ist der Gehäuseabschnitt ein Motordeckel der Handwerkzeugmaschine ist. Der Sturzrahmen kann einen Motordeckel der Handwerkzeugmaschine angespritzt sein.In a further preferred embodiment, the lintel frame is formed in one piece with a housing section of the hand power tool. The housing section is preferably a motor cover of the hand power tool. The lintel frame can be molded onto a motor cover of the hand machine tool.
Es hat sich als vorteilhaft herausgestellt, wenn der Sturzrahmen zwei voneinander beabstandete Kragbügel aufweist. Besonders bevorzugt sind die Kragbügel zu einer Rückseite der Handwerkzeugmaschine hin beabstandet, so dass sich die Akkueinheit komfortabel durch die Kragbügel hindurch in die Aufnahmebucht einschieben lässt. Der Sturzrahmen bildet somit eine Art "Schutzgarage" für die Akkueinheit.It has proven to be advantageous if the lintel frame has two cantilevers spaced apart from one another. The cantilever brackets are particularly preferably spaced apart from the rear of the hand-held power tool, so that the battery unit can be inserted comfortably through the cantilever brackets into the receiving bay. The lintel frame thus forms a kind of "protective garage" for the battery unit.
In einer weiteren bevorzugten Ausgestaltung ist der Sturzrahmen mit einem Handgriff der Handwerkzeugmaschine verschraubt. Vorzugsweise ist jeder der Kragbügel mit dem Handgriff der Handwerkzeugmaschine verschraubt und/oder weist einen formschlüssigen Eingriff zum Handgriff der Handwerkzeugmaschine auf.In a further preferred embodiment, the lintel frame is screwed together with a handle of the hand power tool. Each of the cantilever brackets is preferably screwed to the handle of the hand-held power tool and / or has a positive engagement with the handle of the hand-held power tool.
Es hat sich als vorteilhaft herausstellt, wenn der Sturzrahmen aus einem elastisch verformbaren Kunststoff besteht oder einen solchen aufweist. Eine Elastizität des Sturzrahmens ist vorzugsweise größer, als eine Elastizität eines Hauptgehäuses Handwerkzeugmaschine.It has proven to be advantageous if the lintel frame is made of an elastically deformable plastic or has one. An elasticity of the lintel frame is preferably greater than an elasticity of a main housing of the hand tool.
Besonders bevorzugt ist die elektrischen Handwerkzeugmaschine als Akku-Bohrhammer oder Akku-Kombihammer ausgebildet.The electric hand tool is particularly preferably designed as a cordless rotary hammer or cordless combination hammer.
Die Erfindung wird ebenfalls gelöst durch ein System mit einer akkubetriebenen Handwerkzeugmaschine der vorbeschriebenen Art und mit wenigstens einer Akkueinheit, die zur wiederlösbaren Aufnahme in der Aufnahmebucht der Handwerkzeugmaschine ausgebildet ist. Das System kann eine Akkueinheit unterschiedlicher Größe bzw. mit unterschiedlicher Kapazität aufweisen, wobei die räumliche Ausdehnung des Sturzrahmens festgelegt ist, d.h. insbesondere gleich groß für Akkueinheiten unterschiedlicher Größe ist.The invention is also achieved by a system with a battery-operated hand-held power tool of the type described above and with at least one rechargeable battery unit which is designed for releasable reception in the receiving bay of the hand-held power tool. The system can be a battery unit of different sizes or with different Have capacity, the spatial extent of the lintel frame being fixed, ie in particular the same size for battery units of different sizes.
