Description

Die Erfindung betrifft ein netzbetriebenes Handwerkzeuggerät, wie insbesondere ein Bohrhammer, ein Meißel- oder Schlagbohrgerät, eine motorbetriebene Säge, wie insbesondere eine Stich- oder Säbelsäge, oder ein Trenn- oder Schleifgerät, wie insbesondere ein Winkelschleifgerät. Das Handwerkzeuggerät weist ein Gehäuse, von dem sich ein Netzkabel zum Anschluss an ein Stromnetz weg erstreckt, und eine Verbindungsvorrichtung auf. Diese ist an einer Durchtrittsöffnung des Gehäuses, aus der das Netzkabel aus dem Gehäuse austritt, angeordnet. Zudem weist die Verbindungsvorrichtung elektrische Verbindungsmittel, an denen das Netzkabel anschliessbar ist, sowie Festlegemittel auf, an denen das Netzkabel festlegbar ist. Ferner ist eine durch einen Montagedeckel verschliessbare Montageöffnung des Gehäuses vorgesehen. Durch Beabstandung dieses Montagedeckels vom Gehäuse kann die Verbindungsvorrichtung, beispielsweise bei der Montage oder zu Reparatur- oder Austauschzwecken des Netzkabels, zugänglich gemacht werden.The invention relates to a mains-operated hand tool device, in particular a hammer drill, a chisel or impact drill, a motor-driven saw, in particular a jigsaw or saber saw, or a separating or grinding device, in particular an angle grinder. The hand tool includes a housing from which extends a power cord for connection to a power grid away, and a connection device. This is arranged at a passage opening of the housing, from which the power cord exits from the housing. In addition, the connection device has electrical connection means, to which the power cable can be connected, as well as fixing means, on which the power cable can be fixed. Furthermore, a closable by a mounting cover mounting opening of the housing is provided. By spacing this mounting cover from the housing, the connection device can be made accessible, for example during assembly or for repair or replacement purposes of the power cable.

Bei derartigen Handwerkzeuggeräten kann beispielsweise bei einem notwendigen Austausch des Netzkabels auf eine aufwändige Zerlegung des Gehäuses verzichtet werden. Vielmehr muss hier lediglich der Montagedeckel vom übrigen Gehäuse getrennt werden, um die elektrischen und mechanischen Verbindungen der Verbindungsvorrichtung trennen beziehungsweise herstellen zu können.In such hand tool devices can be dispensed with a costly replacement of the housing, for example, in a necessary replacement of the power cord. Rather, here only the mounting lid must be separated from the rest of the housing to separate or produce the electrical and mechanical connections of the connecting device.

Aus der DE 100 05 989 A1 ist eine Handwerkzeugmaschine bekannt, die im Bereich einer Durchtrittsöffnung eines Netzkabels einen gesonderten Service-Deckel aufweist. Dieser kann vom übrigen Gehäuse losgeschraubt werden. Hierdurch wird ein Bereich freigegeben, in dem alle elektrischen Verbindungsmittel und Festlegemittel vorgesehen sind, die zum Austausch des Netzkabels gelöst beziehungsweise verbunden werden müssen.From the DE 100 05 989 A1 is a hand tool known, which has a separate service cover in the region of a passage opening of a power cord. This can be unscrewed from the rest of the housing. As a result, an area is released in which all electrical connection means and fixing means are provided, which must be solved or connected to replace the power cord.

Durch diesen bekannten Aufbau einer Werkzeugmaschine ist es möglich, den für das Austauschen oder Warten des Netzkabels relevanten Montagebereich allein durch Entfernen des Service-Deckels zugänglich zu machen. Im Übrigen kann das Gehäuse ansonsten geschlossen bleiben.By this known construction of a machine tool, it is possible, the relevant for the replacement or maintenance of the power cable mounting area alone by removing the service cover. Incidentally, the case may otherwise remain closed.

Nachteilig an der bekannten Werkzeugmaschine ist jedoch, dass der Servicedeckel relativ gross ausgebildet werden muss, um einen bequemen Zugang zu allen Verbindungs- und Festlegemitteln zu ermöglichen. Andererseits kann die Stabilität des Gehäuses bei zu grosser Auslegung des Servicedeckels merklich geschwächt werden.A disadvantage of the known machine tool, however, is that the service cover must be made relatively large in order to allow easy access to all connection and Festlegemitteln. On the other hand, the stability of the housing can be noticeably weakened if the service cover is designed too large.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei einem Handwerkzeuggerät die genannten Nachteile zu vermeiden und eine komfortable Zugänglichkeit der Verbindungsvorrichtung bei geringer Schwächung des Gehäuses zu ermöglichen.The present invention has for its object to avoid the disadvantages mentioned in a hand tool and to allow easy accessibility of the connecting device with little weakening of the housing.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass die Verbindungsmittel und die Festlegemittel zumindest teilweise durch die Montageöffnung hindurch aus einem Gehäuseinneren heraus verlagerbar sind. Durch diese Verlagerung an die Aussenseite des Gehäuses sind die Verbindungsmittel und Festlegemittel im Wesentlichen frei zugänglich. Dabei muss die Montageöffnung lediglich gerade so ausgelegt werden, dass die zur Montage und Demontage des Netzkabels relevanten Verbindungsmittel und Festlegemittel durch diese hindurch bewegt werden können. Hierdurch ist es möglich, die Montageöffnung sehr klein zu dimensionieren und dadurch eine ausreichende Stabilität des Gehäuses beizubehalten. Durch die freie Zugänglichkeit der relevanten Verbindungsmittel und Festlegemittel an der Aussenseite des Gehäuses wird gleichzeitig eine besonders komfortable Montage, Demontage oder Wartung des Netzkabels ermöglicht.According to the invention, the object is achieved in that the connecting means and the fixing means are at least partially displaceable out of the housing interior through the mounting opening. By this displacement to the outside of the housing, the connecting means and fixing means are substantially freely accessible. In this case, the mounting opening only needs to be just designed so that the relevant for mounting and dismounting of the power cord connecting means and fixing means can be moved through them. This makes it possible to dimension the mounting hole very small and thereby maintain sufficient stability of the housing. Due to the free accessibility of the relevant connecting means and fixing means on the outside of the housing a particularly convenient assembly, disassembly or maintenance of the power cord is made possible simultaneously.

In einer besonders bevorzugten Ausführungsform sind die Verbindungsmittel und die Festlegemittel dabei an einem Trägerelement gehalten. Dieses Trägerelement ist zwischen einer Betriebsstellung, in der die Verbindungsmittel und die Festlegemittel im Gehäuseinneren angeordnet sind, und einer Offenstellung, in der die Verbindungsmittel und die Festlegemittel zumindest teilweise ausserhalb des Gehäuseinneren angeordnet sind, verschiebbar. Hierdurch ist eine komfortable Handhabung der Verbindungsvorrichtung möglich.In a particularly preferred embodiment, the connecting means and the fixing means are held on a support element. This support element is between an operating position, in which the connecting means and the fixing means are arranged inside the housing, and an open position in which the connecting means and the fixing means are at least partially arranged outside the housing interior, displaceable. As a result, a comfortable handling of the connecting device is possible.

Vorteilhafterweise ist das Trägerelement mit dem Montagedeckel verbunden. Hierdurch wird mit der Beabstandung des Montagedeckels vom Gehäuse gleichzeitig auch die Verbindungsvorrichtung durch die Montageöffnung hindurch bewegt. Auf diese Weise wird die Verbindungsvorrichtung besonders schnell und bequem zugänglich gemacht.Advantageously, the carrier element is connected to the mounting lid. As a result, with the spacing of the mounting lid from the housing at the same time, the connecting device is moved through the mounting opening. In this way, the connecting device is made particularly quick and convenient access.

Bevorzugterweise ist die Durchtrittsöffnung an dem Montagedeckel vorgesehen. Hierdurch erfolgt die Festlegung des Netzkabels allein an dem Montagedeckel, was die Handhabung weiter vereinfacht.Preferably, the passage opening is provided on the mounting lid. As a result, the definition of the power cord is done solely on the mounting lid, which further simplifies handling.

Dabei ist es besonders günstig, wenn die Verbindungsvorrichtung in Richtung der Offenstellung vorgespannt ist. Hierdurch wird die Verbindungsvorrichtung beim Lösen des Montagedeckels vom Gehäuse selbsttätig in die Offenstellung verbracht und in dieser gegenüber dem übrigen Handwerkzeuggerät kraftschlüssig gehalten. Auf diese Weise wird eine stabile Lage der Verbindungsvorrichtung in der Offenstellung gewährleistet, die eine komfortable Handhabung gewährleistet.It is particularly advantageous if the connecting device is biased in the direction of the open position. As a result, the connecting device is automatically removed from the housing when releasing the mounting lid in the open position and held in this force-locking relative to the other hand tool. In this way, a stable position of the connecting device is ensured in the open position, which ensures comfortable handling.

In einer besonders vorteilhaften Ausführungsform ist die Verbindungsvorrichtung durch einen federelastischen Schutzmantel einer geräteseitigen Verkabelung vorgespannt. Hierdurch sind keine separaten Federmittel erforderlich, was die Herstellungskosten vermindert.In a particularly advantageous embodiment, the connecting device is biased by a resilient protective casing of a device-side wiring. As a result, no separate spring means are required, which reduces the manufacturing cost.

Vorteilhafterweise weist die Verbindungsvorrichtung in der Offenstellung einen Endanschlag auf. Auf diese Weise kann einerseits eine günstige Position der Verbindungsvorrichtung vorbestimmt werden, in der auf die Verbindungsmittel und Festlegemittel besonders gut zugegriffen werden kann. Andererseits verbleibt der Montagedeckel hierdurch auch in der Offenstellung am Handwerkzeuggerät, wodurch vermieden wird, dass der Montagedeckel verloren geht.Advantageously, the connecting device in the open position on an end stop. In this way, on the one hand, a favorable position of the connecting device can be predetermined, in which the connecting means and fixing means can be accessed particularly well. On the other hand, the mounting lid thus remains in the open position on the power tool, thereby avoiding that the mounting cover is lost.

Dabei ist es günstig, wenn der Endanschlag durch den Schutzmantel gebildet ist. Auf diese Weise muss kein separater Endanschlag ausgeformt werden, was die Herstellungskosten vermindert.It is advantageous if the end stop is formed by the protective jacket. In this way, no separate end stop must be formed, which reduces the manufacturing cost.

Ferner sind an dem Trägerelement vorteilhafterweise Führungsmittel vorgesehen, die mit gehäusefesten Gegenführungsmitteln zusammenwirken und dabei das Trägerelement gegenüber dem Gehäuse translatorisch führen. Hierdurch erhält man eine schubladenartige Führung des Trägerelementes und damit der gesamten Verbindungsvorrichtung. Dadurch kann in komfortabler Weise zwischen der Betriebsstellung und der Offenstellung gewechselt werden, wobei die Verbindungsvorrichtung in beiden Stellungen gegenüber dem Gehäuse stabil gehalten ist. Auf diese Weise kann sowohl eine komfortable Montage oder Demontage des Netzkabels als auch ein sicherer Betrieb gewährleistet werden.Further, guide means are advantageously provided on the support element, which cooperate with housing-fixed counter-guide means and thereby guide the support member relative to the housing in translation. This gives a drawer-like guidance of the support element and thus the entire connecting device. This can be changed in a comfortable way between the operating position and the open position, wherein the connecting device is held stable in two positions relative to the housing. In this way, both a comfortable assembly or disassembly of the power cord and a safe operation can be ensured.

Fig. 1 zeigt ein netzbetriebenes Handwerkzeuggerät 2, in Form eines Meisselgerätes, das ein Gehäuse 4 aufweist. Zur Stromversorgung des Handwerkzeuggerätes 2 ist ein Netzkabel 6 angeschlossen, das an einem freien Ende 8 mit einen Netzstecker 10 verbunden ist. An einem geräteseitigen Ende 12 ist das Netzkabel 6 mit einer Verbindungsvorrichtung 14 verbunden. Fig. 1 shows a mains-powered hand tool 2, in the form of a chisel device, which has a housing 4. To power the hand tool 2, a power cord 6 is connected, which is connected at a free end 8 with a power plug 10. At a device-side end 12, the power cable 6 is connected to a connecting device 14.

Wie insbesondere aus Fig. 2 zu entnehmen ist, weist die Verbindungsvorrichtung 14 zur Festlegung des Netzkabels 6 eine Tülle 16, die einen Abschnitt des Netzkabels 6 umhüllt und mit einem Montagedeckel 18 verbunden ist, sowie als Kabelbride ausgebildete Festlegemittel 20 auf, die an einem Trägerelement 22 angeordnet sind. In den Montagedeckel 18 ist eine Durchtrittsöffnung 23 eingelassen, über die das Netzkabel 6 aus dem Gehäuse 4 austritt. Das Trägerelement 22 ist an einer von der Tülle 16 abgewandten Seite des Montagedeckels 18 mit diesem verbunden.As in particular from Fig. 2 can be seen, the connecting device 14 for fixing the power cord 6, a spout 16, which covers a portion of the power cord 6 and is connected to a mounting lid 18, and formed as a cable clamp fixing means 20, which are arranged on a support member 22. In the mounting lid 18, a passage opening 23 is inserted, via which the power cord 6 exits from the housing 4. The carrier element 22 is connected to the side facing away from the spout 16 side of the mounting lid 18 with this.

Ferner sind an dem Trägerelement 22 elektrische Verbindungsmittel 24 in Form von Lüsterklemmen vorgesehen. Über diese Verbindungsmittel 24 sind kabelseitige Litzen 26a des Netzkabels 6 mit geräteseitigen Litzen 26b einer Geräteverkabelung 28 elektrisch verbindbar. Dabei ist an dem Trägerelement 22 ferner eine Klemmaufnahme 30 ausgeformt, in der ein Schutzmantel 32 der Geräteverkabelung 28 befestigt werden kann.Furthermore, electrical connection means 24 in the form of luster terminals are provided on the carrier element 22. About this connection means 24 are cable-side strands 26a of the power cord 6 with device-side strands 26b of a device wiring 28 electrically connected. In this case, a clamping receptacle 30 is further formed on the support member 22, in which a protective jacket 32 of the device wiring 28 can be attached.

Darüber hinaus sind an dem Trägerelement 22 Führungsmittel 34 vorgesehen, die mit nutförmigen Gegenführungsmitteln 36 (siehe Fig. 4) des Gehäuses 4 zusammen wirken und dabei eine geführte translatorische Bewegung der Verbindungsvorrichtung 14 gegenüber dem Gehäuse 4 ermöglichen. Die Führungsmittel 34 können dabei, wie dargestellt, durch Kanten des Trägerelementes 22 oder alternativ durch an diesem ausgeformte Rippen gebildet sein. Hierdurch ist die Verbindungsvorrichtung 14 von der in Fig. 1 dargestellten Betriebsstellung nach Lösen zweier Befestigungsschrauben 38, die die Verbindungsvorrichtung 14 an dem Gehäuse 4 sichern, von dem Gehäuse 4 weg in eine Offenstellung verschiebbar, die in Fig. 3 und 4 dargestellt ist. Hierbei wird der Montagedeckel 18 von einer Montageöffnung 40 des Gehäuses 4 abgehoben und das Trägerelement 22 von einem Gehäuseinneren 42 durch die Montageöffnung 40 nach Aussen bewegt.In addition, on the carrier element 22 guide means 34 are provided, which with groove-shaped counter-guide means 36 (see Fig. 4 ) of the housing 4 cooperate and thereby allow a guided translational movement of the connecting device 14 relative to the housing 4. The guide means 34 may, as shown, be formed by edges of the carrier element 22 or alternatively by ribs formed thereon. As a result, the connecting device 14 of the in Fig. 1 shown operating position after loosening two fastening screws 38 which secure the connecting device 14 to the housing 4, displaced away from the housing 4 in an open position, the in Fig. 3 and 4 is shown. Here, the mounting lid 18 is lifted from a mounting opening 40 of the housing 4 and the support member 22 moves from a housing interior 42 through the mounting hole 40 to the outside.

In dieser Offenstellung sind die Festlegemittel 20 und zumindest die Seiten der Verbindungsmittel 24, an denen die kabelseitigen Litzen 26a angeschlossen werden, ausserhalb des Gehäuses 4 angeordnet. Auf diese Weise ist sowohl die mechanische als auch die elektrische Verbindung des Netzkabels 6 mit dem Handwerkzeuggerät 2 besonders gut zugänglich und kann besonders leicht getrennt oder hergestellt werden.In this open position, the fixing means 20 and at least the sides of the connecting means 24, to which the cable-side strands 26a are connected, are arranged outside the housing 4. In this way, both the mechanical and the electrical connection of the power cord 6 with the hand tool 2 is particularly accessible and can be particularly easily separated or manufactured.

Wie aus Fig. 4 ferner zu entnehmen ist, wird die Verbindungsvorrichtung 14 in der Offenstellung vom Schutzmantel 32 der Geräteverkabelung 28 am Gehäuse 4 gehalten. Wenn die Verbindungsvorrichtung 14 in die Betriebsstellung verbracht wird, wird der Schutzmantel 32, wie in Fig. 5 dargestellt gekrümmt. Durch Verwendung eines federelastischen Materials wird hierbei mittels des Schutzmantels 32, der sich am Gehäuse 4 abstützt, eine Rückstellkraft R erzeugt, die an der Klemmaufnahme 30 des Trägerelementes 22 angreift und die Verbindungsanordnung 14 in Richtung der Offenstellung vorspannt. Hierdurch verlagert sich die Verbindungsanordnung 14 nach Lösen der Befestigungsschrauben 38 selbsttätig in die Offenstellung gemäss Fig. 4. Gleichzeitig ist die Länge des Schutzmantels 32 derart bemessen, dass er in der Offenstellung als Endanschlag wirkt und somit ein Herausrutschen der Führungsmittel 34 aus den Gegenführungsmitteln 36 verhindert.How out Fig. 4 can also be seen, the connecting device 14 is held in the open position by the protective jacket 32 of the device wiring 28 on the housing 4. When the connecting device 14 is brought into the operating position, the protective jacket 32, as in Fig. 5 shown curved. By using a resilient material in this case by means of the protective jacket 32, which is supported on the housing 4, a restoring force R is generated, which acts on the clamping receptacle 30 of the support member 22 and biases the connection assembly 14 in the direction of the open position. As a result, the connection assembly 14 shifts automatically after loosening the mounting screws 38 in the open position according to Fig. 4 , At the same time, the length of the protective jacket 32 is dimensioned such that it acts as an end stop in the open position and thus prevents the guide means 34 from slipping out of the counter-guide means 36.
