Abstract

The hand tool has a handle (2) extending from a housing (1), which is itself shaped ergonomically as a hand grip (3) on the side opposite the grinding head. An additional grip piece (4), which is spaced apart from the handle, is connected to the handle by an ergonomically shaped knob (5). The knob is mounted on an arm (6) which can pivot on the housing or slide within it. When the knob is in the folded position or slid within the housing, it matches the contours of the housing to form a continuous surface. When it is folded outwards or withdrawn into the housing, the rear (14) of the grip piece suits the shape of the ball of the thumb.

Description

Die Erfindung betrifft ein motorbetriebenes Handwerkzeug wie Exzenter-, Winkel- oder Schwingschleifer mit einem an das Gehäuse angeformten Handgriff, wobei die dem Schleifkopf gegenüberliegende Seite des Gehäuses ergonomisch als Griff ausgebildet ist.The invention relates to a motor-operated hand tool such as Eccentric, angle or orbital sander with one on the housing molded handle, the opposite of the grinding head Side of the housing is ergonomically designed as a handle.

Es ist beispielsweise ein derartiges motorbetriebenes Handwerkzeug bekannt (EP 0791 435 A1), das als handgeführter Exzenterschleifer betrieben wird. Um ein besseres Halten oder Abstützen des Handwerkzeuges zu ermöglichen, ist dieses mit einem Zusatzhandgriff versehen, der abnehmbar in der Nähe des exzentrisch angetriebenen Schleifkopfes im unteren Bereich des Werkzeugkörpers angebracht werden kann. Der wesentliche Nachteil dieser bekannten Ausführungsform besteht darin, daß ein solcher Handgriff verlierbar ist und aus Platzgründen auch nach dem Gebrauch des Gerätes abmontiert werden muß. Ein Abmontieren des Handgriffes ist auch dann notwendig, wenn man beispielsweise an einer Kante entlang schleifen muß.It is, for example, such a motor-operated hand tool known (EP 0791 435 A1) that as a hand-held random orbital sander is operated. To better hold or support the hand tool to make this possible with an additional handle provided, the removable near the eccentrically driven Grinding head attached in the lower area of the tool body can be. The main disadvantage of this known embodiment is that such a handle can be lost and out Space reasons can also be removed after using the device got to. It is also necessary to remove the handle if you have to sand along an edge, for example.

Der Erfindung liegt die Aufgabe zugrunde, bei einem solchen motorbetriebenen Handwerkzeug den Handgriff so auszubilden, daß er unverlierbar Bestandteil des Gerätes ist und zur optimalen Handhabung in jeder Gebrauchslage eine günstige ergonomische Form aufweist.The invention has for its object in such a motor-driven Hand tool to train the handle so that it captive is part of the device and for optimal handling has a favorable ergonomic shape in every position of use.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß sich an den Griff, vom Handgriff weggerichtet, ein Zusatzgriffteil mit einem ergonomisch an den Griff angepaßten Knauf anschließt, der an einem Arm angeformt ist, wobei der Arm am Gehäuse verschwenkbar oder herausziehbar bzw. einschiebbar gehaltert ist und die Kontur des Knaufs bei eingeklapptem bzw. eingeschobenem Zusatzgriffteil mit der Gehäuseoberkontur des Griffes eine einheitliche Kontur aufweist und daß bei ausgeklapptem bzw. herausgezogenem Zusatzgriffteil die Rückseite des Griffteils ergonomisch an den Handballen angepaßt ist.This object is achieved according to the invention in that the Handle, directed away from the handle, an additional handle part with a ergonomically adapted to the handle knob that connects to one Arm is integrally formed, the arm being pivotable on the housing or is pulled out or inserted and the contour of the Knaufs with the additional handle part folded in or pushed in with the Housing contour of the handle has a uniform contour and that when the additional handle part is folded out or pulled out Back of the grip part is ergonomically adapted to the ball of the hand.

Eine vorteilhafte Ausführungsform sieht vor, daß der Arm nahe dem Schleifkopf mittels einer Achse an Buchsen gehaltert ist und die Schwenkposition des Armes mittels einer Feststellschraube festlegbar ist.An advantageous embodiment provides that the arm near the Grinding head is held on bushings by means of an axis and the Swivel position of the arm can be determined using a locking screw is.

Weiter ist es vorteilhaft, daß das Zusatzgriffteil als Verlängerung des Griffs in das Gehäuse einschiebbar bzw. herausziehbar ist und in beiden Positionen ergonomisch an den jeweiligen Einsatzzweck angepaßt ist.It is also advantageous that the additional handle part as an extension of Handle can be inserted or withdrawn into the housing and in both positions ergonomically to the respective application is adjusted.

Die Erfindung wird in der nachfolgenden Beschreibung anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert.The invention is described in the following description based on a illustrated in the drawings embodiment.

Das in den Zeichnungen dargestellte Gerät weist einen an einem Gehäuse 1 angeformten Handgriff 2 auf, wobei der an den Handgriff anschließende Gehäuseteil, d.h. die Gehäuseoberkontur ergonomisch als Griff 3 ausgebildet ist. Diesem Griff 3 gegenüberliegend befindet sich ein Schleifkopf 7 mit einer Schleifscheibe 12.The device shown in the drawings has one on one Housing 1 integrally formed handle 2, which is attached to the handle subsequent housing part, i.e. the upper contour of the housing is ergonomic Handle 3 is formed. This handle 3 is located opposite a grinding head 7 with a grinding wheel 12.

An dem Griff 3, und zwar weggerichtet vom Handgriff 2, schließt sich ein Zusatzgriffteil 4 mit einem ergonomisch geformten Knauf 5 als Fortsetzung und Abschluß des Griffes 3 an, wobei dieser Knauf 5 an seiner Vorderseite 13 abgerundet ist. Die Gehäuseoberkontur ergibt somit mit der Knaufkontur des Zusatzhandgriffes 4 bei eingeklapptem Zusatzhandgriff 4 eine optimale Ergonomie.On the handle 3, facing away from the handle 2, closes an additional handle part 4 with an ergonomically shaped knob 5 as Continuation and completion of the handle 3, this knob 5 on its front 13 is rounded. The upper contour of the housing results thus with the knob contour of the additional handle 4 when folded Additional handle 4 optimal ergonomics.

Dieser Griffteil 4 ist als selbständiges Teil an einem Arm 6 mit dem Knauf 5 verschwenkbar angeordnet, wobei in der einen Gebrauchsstellung (Fig. 1 und 2) der Arm 6 am Gehäuse 1 anliegt. In weiteren Gebrauchsstellungen (z.B. Fig. 3) kann dieser Zusatzgriffteil 4 vom Gehäuse 1 abgeklappt werden. Dazu sind an dem Arm 6 an seinem unteren Ende Buchsen 10 im Abstand zueinander angeformt, die dazwischen eine gehäuseseitige Haltescheibe 8 aufnehmen. Durch die Buchsen 10 und die Haltescheibe 8 ist eine Achse 9 hindurchgesteckt und der Arm 6 kann an der einen Seite mit Hilfe einer auf die Achse 9 aufgeschraubten Feststellschraube 11 in jeder beliebigen Schwenkposition festgestellt werden. Wird der Zusatzhandgriff 4 ausgeklappt, so stellt die abgeflachte Rückseite 14 wiederum eine ergonomisch exakt auf den Handballen angepaßte Griffposition dar. This grip part 4 is as an independent part on an arm 6 with the Knob 5 arranged pivotably, in the one position of use (Fig. 1 and 2) the arm 6 abuts the housing 1. In others Use positions (e.g. Fig. 3) this additional handle part 4 from Housing 1 can be folded down. These are on the arm 6 on his molded lower end bushings 10 at a distance from each other, the in between a housing-side holding disc 8. Through the Bushings 10 and the holding disc 8, an axis 9 is inserted and the arm 6 can on one side with the help of the axis 9 screwed locking screw 11 in any swivel position be determined. If the additional handle 4 is folded out, so the flattened back 14 in turn is ergonomically precise grip position adjusted on the ball of the hand.

Der Zusatzhandgriff kann auch anstelle des Verschwenkens in dem Gehäuse 1 einschiebbar bzw. herausziehbar gelagert sein (Fig. 4). Bei der gezeigten Ausführungsform ist sein Arm 6' als Verlängerung des Griffs 3 in Gehäuse 1 geführt. In der herausgezogenen Position ist seine Rückseite 14 dann an den Handballen ergonomisch angepaßt. Eingeschoben ergibt sich eine Anpassung an die Gehäuseform.The additional handle can also be used instead of pivoting in the Housing 1 can be inserted or pulled out (Fig. 4). At the embodiment shown is his arm 6 'as an extension of Handle 3 guided in housing 1. In the pulled out position its back 14 then ergonomically adapted to the heel of the hand. When inserted, there is an adaptation to the housing shape.
