Description

Die Erfindung bezieht sich auf ein Elektrowerkzeug gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a power tool according to the Preamble of claim 1.

Bei einem durch die EP-PS 00 71 536 bekannten Elektrowerkzeug dieser Art ist die im Werkzeuggehäuse für die Aufnahme des "battery pack" vorgesehene Kammer für eine definierte Baugröße des Batterie-Packens nach Kapazität und Spannung bemessen.In a power tool known from EP-PS 00 71 536 This is the type in the tool housing for the "battery pack "intended chamber for a defined size of the Battery packs are dimensioned according to capacity and voltage.

Die Lagefixierung des Batteriepackens erfolgt dabei mittels einer verschwenkbaren Klappe die nach dem Einsetzen des Batterie-Packens in die Aufnahmekammer in die Halteposition geschwenkt und in dieser Lage verriegelt wird.The position of the battery pack is fixed using a hinged flap after inserting the battery pack pivoted into the holding position in the holding chamber and in this Location is locked.

Eine Bestückung des hier als Bohrmaschine ausgebildeten Elektro­ werkzeugs mit Batterie-Packen unterschiedlicher Kapazität und/oder Spannung ist hier weder vorgesehen noch möglich.An assembly of the electrical, which is designed here as a drilling machine tool with battery packs of different capacities and / or Tension is neither provided nor possible here.

Fig. 8 die Baueinheit Elektrowerkzeug (Schrauber), Kupp­ lungsbauteil und Batterie-Packen im Vereinigungs­ zustand. Fig. 8, the unit power tool (screwdriver), hitch be component and battery pack in the unification state.

In Fig. 1 ist mit 1 das Elektrowerkzeug in Form eines Schraubers bezeichnet, dessen Gehäuse 2 wenigstens zum Teil als Aufnahme­ kammer für einen Batterie-Packen 3 dient. Zwischen dem Werkzeug­ gehäuse 2 und dem Batterie-Packen 3 befindet sich das Kupplungs­ bauteil 4, das hier als mit einer Längsriffelung 5 versehener Ring ausgebildet ist.In Fig. 1, 1 denotes the power tool in the form of a screwdriver, the housing 2 of which at least partially serves as a receiving chamber for a battery pack 3 . Between the tool housing 2 and the battery pack 3 there is the coupling component 4 , which is designed here as a ring with a longitudinal corrugation 5 .

Das Kupplungsbauteil 4 weist, wie aus den Fig. 2 bis 5 ersicht­ lich ist, am Innenumfang seines dem Werkzeuggehäuse zugewandten Abschnitts 6 vier in Umfangsrichtung um 90° räumlich zueinander versetzt liegende wulstartige Erhebungen 7 auf, die im Ver­ einigungszustand des Kupplungsbauteils 4 mit dem Werkzeuggehäuse 2 in in dessen Endbereich angebrachten, in Umfangsrichtung verlaufen­ de Ausnehmungen 8 einrasten (siehe hierzu Fig. 1 und 6) . The coupling component 4 , as can be seen from FIGS . 2 to 5, on the inner circumference of its section 6 facing the tool housing, has four bead-like elevations 7 which are spaced apart from one another in the circumferential direction by 90 ° and which, in the state of unification of the coupling component 4 with the tool housing 2 engage in recesses 8 in its end area, which run in the circumferential direction (see FIGS. 1 and 6).

Die Ausnehmungen 8 sind dabei länger bemessen als die Erhebungen 7. Auf diese Weise ist das Kupplungsbauteil 4 drehbar und zugleich unverlierbar mit dem Werkzeuggehäuse 2 verbunden.The recesses 8 are dimensioned longer than the elevations 7 . In this way, the coupling component 4 is rotatable and at the same time captively connected to the tool housing 2 .

Am Innenumfang seines dem Batterie-Packen 3 zugeordneten Abschnitts 6′ enthält das Kupplungsbauteil 4 an zwei einander diametral gegenüberliegenden Bereichen zwei in Achsrichtung verlaufende Halbrundnocken 9 und eine dazwischenliegende, sich senkrecht zu den beiden Nocken 9 erstreckende halbzylindrische Erhebung 10. Den Halbrundnocken 9 und der halbzylindrischen Erhebung 10 ist, wie die Fig. 1 und 7 erkennen lassen, jeweils eine L-förmige Aussparung 11 am Batterie-Packen 3 zugeordnet, derart, daß der Batterie-Packen 3 mit dem Kupplungsbauteil 4 nach Art eines Bajonettverschlusses vereinigbar ist. Die beiden Halbrundnocken 9 des Kupplungsbauteils 4 greifen beim Vereinigungsvorgang mit dem Batterie-Packen 3 jeweils in den in Achsrichtung dieses Packens verlaufenden Bereich der Aussparung 11 ein, wobei die halbzylindrische Erhebung 10 im Kupplungsbauteil 4 eine ähn­ lich ausgebildete Erhebung 12 im Bereich der Aussparung 11 am Batterie-Packen 3 überrastet. Durch eine Relativdrehung zwischen dem Kupplungsbauteil 4 und dem Batterie-Packen 3 gelangen die Halbrundnocken 9 in den in Umfangsrichtung verlaufenden Teil der Aussparung 11 (Hinterschneidung) im Batterie-Packen 3. In der Verriegelungslage des Batteriepackens 3 überrasten der in Dreh­ richtung vordere Halbrundnocken 9 einen korrespondierenden Nocken 16 am Batteriepacken 3. Damit ist der Batterie-Packen in seiner Lage fixiert und gegen Herausfallen gesichert.At the inner periphery of the battery pack 3 associated section 6 'the clutch member 4 at two diametrically opposed portions comprises two axially extending semi-circular cam 9 and an intermediate, perpendicular to the two cam 9 extending semi-cylindrical boss 10 degrees. The semicircular cams 9 and the semi-cylindrical elevation 10 , as can be seen in FIGS. 1 and 7, are each assigned an L-shaped recess 11 on the battery pack 3 , such that the battery pack 3 with the coupling component 4 in the manner of a bayonet catch can be combined. The two semicircular cams 9 of the coupling component 4 engage in the process of merging with the battery pack 3 in the area of the recess 11 extending in the axial direction of this packing, the semi-cylindrical elevation 10 in the coupling component 4 having a similarly designed elevation 12 in the region of the recess 11 on Battery pack 3 snapped into place. By means of a relative rotation between the coupling component 4 and the battery pack 3 , the semicircular cams 9 get into the part of the recess 11 (undercut) in the battery pack 3 that runs in the circumferential direction. In the locked position of the battery pack 3, the front half-round cam 9 in the direction of rotation latch over a corresponding cam 16 on the battery pack 3 . The battery pack is thus fixed in its position and secured against falling out.

Anstelle der beschriebenen, eine besonders zuverlässige Ver­ einigung des Batterie-Packens 3 mit dem Kupplungsbauteil 4 und damit mit dem Elektrowerkzeug ermöglichende Anordnung kann auch ein einfacher Bajonettverschluß verwirklicht werden, z.B. durch Eingriff zweier einfach ausgebildeter, am Kupplungsbauteil 4 angebrachter Nocken in die L-förmige Aussparung am Batterie-Packen 3. Des weiteren können auch andere bekannte Mittel zur Vereinigung des Kupplungs­ bauteils 4 mit dem bzw. einem Batterie-Packen angewandt werden. Instead of the described, a particularly reliable Ver unification of the battery pack 3 with the coupling component 4 and thus with the power tool arrangement, a simple bayonet lock can also be realized, for example by engaging two simply designed cams on the coupling component 4 in the L-shaped Notch on the battery pack 3 . Furthermore, other known means for combining the coupling component 4 with or a battery pack can be applied.

Beim Aufschieben des Kupplungsbauteils 4 auf das Gehäuse 2 des Elektrowerkzeugs bzw. Schraubers sind die wulstartigen Erhebungen 7 des Kupplungsbauteils mit den Schrägflächen 8′ im Endbereich der Wandung des Werkzeuggehäuses 2 in Deckungsposition zu bringen und in die jeweils zugeordnete Ausnehmung 8 im Werkzeuggehäuse einzu­ drücken. Damit ist das für diesen Zweck ausreichende Elastizität auf­ weisende Kupplungsbauteil 4 unverlierbar und im Rahmen des durch die Erstreckung der Ausnehmungen 8 in Umfangsrichtung festgelegten Winkelbereichs verdrehbar mit dem Werkzeuggehäuse 2 vereinigt. Gegebenenfalls können auch besondere, den Drehwinkelbereich des Kupplungsbauteils 4 begrenzende Anschläge am Werkzeuggehäuse 2 und/oder am Kupplungsbauteil 4 angebracht sein.When sliding of the coupling member 4 on the housing 2 of the power tool or wrench the bead-like elevations are to be brought 7 of the coupling member with the inclined surfaces 8 'in the end region of the wall of the tool housing 2 in covering position and press einzu in the respectively associated recess 8 in the tool housing. The elasticity which is sufficient for this purpose on the coupling component 4 which is pointing is captive and is rotatably combined with the tool housing 2 within the angular range defined by the extent of the recesses 8 in the circumferential direction. If necessary, special stops limiting the angle of rotation of the coupling component 4 can also be attached to the tool housing 2 and / or to the coupling component 4 .

Die Lagefixierung des Kupplungsbauteils 4 am Werkzeuggehäuse 2 ergibt sich durch zusammenwirken eines Nocken 13 im Werkzeugge­ häuse 2 mit einem Vorsprung 14 im Kupplungsbauteil 4, die über­ rasten müssen (siehe Fig. 2, 3 und 6).Die Einführung des Vor­ sprungs 14 wird dabei durch die auf gleicher Ebene liegenden Aussparungen 15 und 15′ am Sockel des Werkzeuggehäuses ermöglicht.The position fixation of the coupling member 4 on the tool housing 2 is obtained by cooperation of a cam 13 housing in Werkzeugge 2 with a projection 14 in the coupling member 4, and which must rest (see Fig. 2, 3 and 6) .The introduction of the pre jump 14 is thereby through the same level recesses 15 and 15 'on the base of the tool housing.

In der in Fig. 8 gezeigten Betriebslage des betreffenden Batterie­ packens 3 im Kupplungsbauteil 4 ist der Batteriepacken durch die miteinander korrespondierenden Erhebungen 10 (Kupplungsbau­ teil) und Erhebung 12 (Batteriepacken) in seiner Lage gesichert (siehe Fig. 2, 3, 4, 5 und 7), wobei die beiden Erhebungen wieder über­ rasten. Die Trennlage ergibt sich durch eine solche Relativdrehung zwischen Batteriepacken 3 und Kupplungsbauteil 4, daß die Verrastele­ mente 10 und 12 außer Eingriff miteinander kommen.In the operating position of the relevant battery pack 3 in the coupling component 4 shown in FIG. 8, the battery pack is secured in its position by the corresponding elevations 10 (coupling component) and elevation 12 (battery packs) (see FIGS. 2, 3, 4, 5 and 7), the two elevations again racing over. The separation position results from such a relative rotation between the battery pack 3 and coupling component 4 that the Verrastele elements 10 and 12 come out of engagement with each other.

Das Kupplungsbauteil 4, das erforderlichenfalls auch anders aus­ gebildet sein kann, ermöglicht somit das Bestücken des betreffen­ den Elektrowerkzeugs mit Batterie-Packen verschiedener Kapazität und Spannung. Hierfür ist lediglich Voraussetzung, daß der jeweilige Batterie-Packen eine mechanisch sichere und funktionsgerechte Vereinigung mit dem Kupplungsbauteil zuläßt.The coupling component 4 , which can also be formed differently if necessary, thus enables the relevant power tool to be equipped with battery packs of different capacities and voltages. The only requirement for this is that the respective battery pack allows mechanically safe and functional connection with the coupling component.
