Description

Die Erfindung betrifft ein Elektrogerät, insbesondere eine elektrische Handwerkzeugmaschine gemäß dem Oberbegriff des Anspruchs 1. So eine Vorrichtung ist aus DE 2920065 A1 bekannt.The invention relates to an electrical appliance, in particular an electric hand tool according to the preamble of claim 1. Such a device is made DE 2920065 A1 known.

Um eine Umschaltung von elektrischen Handwerkzeugmaschinen oder anderen Elektrogeräten zwischen verschiedenen Drehzahlen, zwischen verschiedenen Betriebsarten, wie zum Beispiel Bohr- und Meißelbetrieb, Akku- und Netzbetrieb, Rechts- und Linkslauf oder zwischen anderen verstellbaren Funktionen zu ermöglichen, weisen die Elektrogeräte häufig an der Außenseite ihres Gehäuses ein drehbares Bedienungs- oder Bedienungselement auf, zum Beispiel einen Drehknopf, der drehfest mit einem innerhalb des Gehäuses untergebrachten Funktionselement, zum Beispiel einem Schaltexzenter, verbunden ist, so dass eine von einem Bediener außerhalb des Gehäuses vorgenommene Drehung des Bedienungselements zu einer entsprechenden Drehung des Funktionselements innerhalb des Gehäuses führt. Die drehfeste Verbindung zwischen dem Bedienungselement und dem Funktionselement ist gewöhnlich eine Schraubverbindung.In order to enable a switchover of electric power tools or other electrical equipment between different speeds, between different modes, such as drilling and chiseling, battery and mains operation, clockwise or counterclockwise or between other adjustable functions, the electrical appliances often have on the outside of their Housing a rotatable operating or operating element, for example, a rotary knob which is non-rotatably connected to a housed within the housing functional element, for example, a switching eccentric connected, so that made by an operator outside the housing rotation of the operating element to a corresponding rotation of the Function element within the housing leads. The rotationally fixed connection between the operating element and the functional element is usually a screw connection.

Schraubverbindungen haben jedoch einige Nachteile: Durch das Erfordernis einer Schraube wird die Anzahl der benötigten Teile vergrößert. Wenn eine sehr kleine Schraube gewählt wird, kann zwar der für die Schraubverbindung benötigte Bauraum klein gehalten werden, jedoch erschwert eine kleine Schraube auf der anderen Seite die Herstellung der Schraubverbindung, wofür darüber hinaus ein Schraubwerkzeug erforderlich ist. Außerdem können sich Schraubverbindungen unter Umständen beim Drehen des Bedienungselements in einer Drehrichtung lösen, wenn keine speziellen Gegenmaßnahmen getroffen werden.However, screw connections have some disadvantages: the requirement of a screw increases the number of parts required. If a very small screw is selected, while the space required for the screw connection can be kept small, but a small screw on the other hand makes it difficult to produce the screw, what moreover a screwing tool is required. In addition, screw connections can possibly solve when turning the operating element in one direction of rotation, if no special countermeasures are taken.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Elektrogerät der eingangs genannten Art dahingehend zu verbessern, dass sich die drehfeste Verbindung zwischen dem außerhalb des Gehäuses angeordneten Bedienungselement und dem innerhalb des Gehäuses angeordneten Funktionselement ohne Werkzeug und ohne die Notwendigkeit zusätzlicher Teile einfach, schnell und kostengünstig herstellen lässt.Based on this, the present invention seeks to improve an electrical appliance of the type mentioned in that the rotationally fixed Connection between the outside of the housing arranged operating element and arranged within the housing functional element without tools and without the need for additional parts easily, quickly and inexpensively.

Offenbarung der ErfindungDisclosure of the invention

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Bedienungselement und das Funktionselement durch eine Öffnung des Gehäuses hindurch miteinander verrastet sind.This object is achieved in that the operating element and the functional element are latched together through an opening of the housing.

Die erfindungsgemäße Merkmalskombination gestattet es, die Verbindung zwischen Bedienungselement und Funktionselement ohne Werkzeug und ohne die Notwendigkeit zusätzlicher Teile einfach, schnell und kostengünstig herzustellen. Darüber hinaus ist eine als Rastverbindung ausgebildete Verbindung wieder lösbar, so dass auch eine zerstörungsfreie Demontage möglich ist.The combination of features according to the invention makes it possible to produce the connection between operating element and functional element without tools and without the need for additional parts simply, quickly and cost-effectively. In addition, a connection formed as a latching connection is releasable again, so that a non-destructive disassembly is possible.

Eine Rastverbindung zwischen dem Bedienungselements und dem Funktionselement ist außerdem sicherer als eine Schraubverbindung und benötigt darüber hinaus auch weniger Platz, vor allem wenn gemäß einer bevorzugten Ausgestaltung der Erfindung ein Teil von einem von dem Funktionselement und dem Bedienungselement durch die Öffnung des Gehäuses in eine Aufnahme des anderen von dem Funktionselement und dem Bedienungselement ragt und in der Aufnahme sowohl verrastet als auch gegen Verdrehen gesichert ist.A locking connection between the operating element and the functional element is also safer than a screw and also requires less space, especially if according to a preferred embodiment of the invention, a part of one of the functional element and the operating element through the opening of the housing in a receptacle of protrudes from the other of the functional element and the operating element and is both locked in the receptacle and secured against rotation.

Zweckmäßig wird ein Vorsprung des Funktionselements von innen her durch die Öffnung des Gehäuses in eine Aufnahmebuchse des Bedienungselements eingeführt. Da der Vorsprung einen kleineren Durchmesser als die Aufnahmebuchse hat, kann auf diese Weise der Öffnungsquerschnitt gering gehalten werden.Suitably, a projection of the functional element is introduced from the inside through the opening of the housing in a receiving socket of the operating element. Since the projection has a smaller diameter than the receiving socket, the opening cross-section can be kept low in this way.

Zudem ist eine Abdichtung der Öffnung mittels einer O-Ring-Dichtung mit kleinem Durchmesser möglich, vor allem wenn diese den durch die Öffnung des Gehäuses ragenden Teil des Funktionselements umgibt, wobei sie zweckmäßig in einer Ausnehmung des Gehäuses angeordnet ist und nach dem Verrasten des Bedienungselements mit dem Funktionselement von einem der beiden Elemente in axialer Richtung ihrer Drehachse in der Ausnehmung festgehalten wird. Durch diese Lösung lassen sich auch Reib- und Bedienkräfte minimieren.In addition, a seal of the opening by means of an O-ring seal with a small diameter is possible, especially if this through the opening of the Housing protruding part of the functional element surrounds, wherein it is expediently arranged in a recess of the housing and is held in the recess after locking the operating element with the functional element of one of the two elements in the axial direction of its axis of rotation. This solution also minimizes friction and operator forces.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung umfassen das Funktionselement und das Bedienungselement komplementäre, im Rasteingriff stehende Rastmittel, wobei zweckmäßig eines der Rastmittel über einen durch die Öffnung ragenden Teil des Funktionselements oder Bedienungselements übersteht, was ebenfalls zur Verkleinerung des Öffnungsdurchmessers beiträgt.According to a further preferred embodiment of the invention, the functional element and the operating element complementary, in locking engagement locking means, expediently one of the locking means projects beyond a projecting through the opening part of the functional element or operating element, which also contributes to the reduction of the opening diameter.

Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass das Funktionselement und das Bedienungselement formschlüssig ineinander greifende Verdrehsicherungsmittel umfassen, die vorteilhaft in Richtung einer Drehachse des Funktionselements und des Bedienungselements im axialen Abstand von den Rastmitteln angeordnet sind, so dass bei der Montage zuerst die Verdrehsicherungsmittel formschlüssig ineinander greifen, bevor die komplementären Rastmittel miteinander in Rasteingriff treten.A further preferred embodiment of the invention provides that the functional element and the operating element positively locking interlocking anti-rotation means advantageously arranged in the direction of a rotation axis of the functional element and the operating element at an axial distance from the locking means, so that during assembly first, the anti-rotation lock form-fitting engage each other before the complementary locking means engage with each other in latching engagement.

Durch die erfindungsgemäße Merkmalskombination lassen sich außerdem sowohl das Bedienungselement und das Funktionselement einstückig durch Spritzgießen aus Kunststoff herstellers, wobei die Rastmittel und die Verdrehsicherungsmittel vorzugsweise einstückig am Funktionselement bzw. am Bedienungselement angeformt oder in dieselben eingeformt werden.The combination of features according to the invention also allows both the operating element and the functional element in one piece by injection molding of plastic manufacturer, wherein the locking means and anti-rotation means are preferably integrally formed on the functional element or on the operating element or molded into the same.

Ausführungsform der ErfindungEmbodiment of the invention

Die in der Zeichnung dargestellte Handwerkzeugmaschine in Form eines Bohrhammers 2 besteht im Wesentlichen aus einem Gehäuse 4, einem Werkzeughalter 6 zur Aufnahme eines SDS-Bohrwerkzeugs, sowie einer vom Gehäuse 4 umschlossenen Antriebseinrichtung (nicht dargestellt) zum drehenden und/oder schlagenden Antreiben des in den Werkzeughalter 6 eingesetzten Werkzeugs.The hand tool shown in the drawing in the form of a hammer drill 2 consists essentially of a housing 4, a tool holder 6 for receiving an SDS drilling tool, and a housing 4 enclosed by the drive device (not shown) for rotating and / or beating driving in the Tool holder 6 used tool.

Zur Wahl der jeweiligen Betriebsart des Bohrhammers 2 unter den Alternativen Bohren mit rein drehendem Antrieb, Hammerbohren mit kombiniertem drehendem und schlagendem Antrieb, Meißeln mit rein schlagendem Antrieb und Meißeln in einer optimalen ermüdungsarmen Arbeitsstellung (Vario Lock) ist an einer Seite des Gehäuses 4 ein Betriebsarten-Wahlschalter in Form eines Drehknaufs 8 angebracht, der sich in Bezug zum Gehäuse 4 um eine von der Mittelachse des Drehknaufs 8 gebildete Drehachse 10 in vier diskrete Schaltstellungen verdrehen und in den Schaltstellungen arretieren lässt, die jeweils einer der vier zuvor oben genannten Betriebsarten entsprechen.To select the respective operating mode of the hammer drill 2 under the alternative drilling with purely rotating drive, hammer drilling with combined rotating and beating drive, chiselling with pure beating drive and chiselling in an optimal low-fatigue working position (Vario Lock) is on one side of the housing 4 a mode Selector switch in the form of a knob 8 is mounted, which rotate with respect to the housing 4 about a formed of the central axis of the rotary knob 8 axis of rotation 10 in four discrete switching positions and lock in the switching positions, each corresponding to one of the four above-mentioned modes.

Die jeweilige Betriebsart des Bohrhammers 2 wird dabei durch die Drehstellung eines in Verlängerung der Drehachse 10 im Inneren des Gehäuses 4 untergebrachten drehbaren Schaltelements 12 festgelegt, dessen Drehachse mit der Drehachse 10 des Drehknaufs 8 fluchtet und das durch eine Öffnung 14 des Gehäuses 4 und speziell eines Getriebedeckels des Bohrhammers drehfest mit dem Drehknauf 8 verbunden ist, so dass die Drehstellung des Drehknaufs 8 stets der Drehstellung des Schaltelements 12 entspricht.The respective operating mode of the hammer drill 2 is determined by the rotational position of an accommodated in extension of the axis of rotation 10 in the interior of the housing 4 rotatable switching element 12 whose axis of rotation is aligned with the axis of rotation 10 of the rotary knob 8 and through an opening 14 of the housing 4 and especially one Transmission cover of the rotary hammer rotatably connected to the rotary knob 8, so that the rotational position of the rotary knob 8 always corresponds to the rotational position of the switching element 12.

Die Öffnung 14 des Gehäuses 4 weist einen kreisförmigen Öffnungsquerschnitt auf und ist von einem nach außen zu stufenförmig erweiterten Begrenzungsrand umgeben, so dass um das äußere Ende der Öffnung 14 herum eine ringförmige Gehäusevertiefung 16 als Sitz für eine O-Ring-Dichtung 18 geschaffen wird. Die O-Ring-Dichtung 18 dient dazu, im Bereich des Betriebsarten-Wahlschalters ein Eindringen von Staub oder anderen Verunreinigungen in das Gehäuse 4 des Bohrhammers 2 zu verhindern. Der Begrenzungsrand der Öffnung 14 steht im Inneren der Gehäuses 4 etwas über die umgebende Gehäusewand über, wobei der Überstand 20 auf seiner zylindrischen Außenseite mit vier eingeformten Aufnahmetaschen 22 (nur eine sichtbar) versehen ist. Die Aufnahmetaschen 22 dienen zur Aufnahme einer im Schaltelement 12 integrierten Arretierkugel 24, die von einer ebenfalls im Schaltelement 12 integrierten Schraubendruckfeder 26 radial von außen her gegen den Überstand 20 angepresst wird und in den vier diskreten Schaltstellungen des Drehknaufs 8 jeweils teilweise in eine der vier Aufnahmetaschen 22 eintritt, um dadurch das Schaltelement 12 zusammen mit dem Drehknauf 8 in der jeweiligen Schaltstellung zu arretieren.The opening 14 of the housing 4 has a circular opening cross-section and is surrounded by an outwardly to step-shaped widening boundary edge, so that around the outer end of the opening 14 around an annular housing recess 16 is provided as a seat for an O-ring seal 18. The O-ring seal 18 serves to prevent the penetration of dust or other contaminants into the housing 4 of the hammer drill 2 in the region of the mode selector switch. The boundary edge of the opening 14 projects slightly beyond the surrounding housing wall in the interior of the housing 4, wherein the projection 20 is provided on its cylindrical outer side with four molded receiving pockets 22 (only one visible). The receiving pockets 22 serve to receive an integrated in the switching element 12 Arretierkugel 24 which is pressed by a likewise integrated in the switching element 12 helical compression spring 26 radially from the outside against the supernatant 20 and in the four discrete switching positions of the rotary knob 8 each partially into one of the four receiving pockets 22 enters to thereby lock the switching element 12 together with the rotary knob 8 in the respective switching position.

Wie am besten in Fig. 2 dargestellt, umfasst der einstückig durch Spritzgießen aus Kunststoff hergestellte Drehknauf 8 einen flachen scheibenförmigen Unterteil 28 mit kreisförmigem Umriss, über den ein diametral zum Umriss ausgerichteter Betätigungsvorsprung 30 übersteht. Wie in Fig. 2 und 3 dargestellt, wird ein äußerer Umfangsrand 32 des Unterteils 28 auf etwas mehr als der Hälfte seines Umfangs von einem Teil 34 des Gehäuses 4 übergriffen, das mit vier symbolischen Darstellungen 36, 38, 40, 42 (Fig. 2) für die vier Schaltstellungen bzw. für die vier Betriebsarten Bohren, Meißeln, Bohren und Meißeln sowie Vario Lock versehen ist.How best in Fig. 2 shown, the integrally formed by injection molding of plastic knob 8 comprises a flat disk-shaped lower part 28 with a circular outline, over which a diametrically aligned to the outline actuating projection 30 protrudes. As in Fig. 2 and 3 1, an outer circumferential edge 32 of the lower part 28 is overlapped by slightly more than half of its circumference by a part 34 of the housing 4 which is provided with four symbolic representations 36, 38, 40, 42 (FIG. Fig. 2 ) for the four switching positions or for the four operating modes drilling, chiselling, drilling and chiselling as well as Vario Lock.
