Description
Die Erfindung betrifft eine Handwerkzeugmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a hand tool according to the preamble of claim 1.
Durch die EP-A-0657255 und durch die EP-A-0653364 sind gattungsgemäße Handwerkzeugmaschinen bekannt, mit länglichem Gehäuse mit zum Gehäusehauptteil abgewinkelt angeordnetem, rotierendem Werkzeug, wobei das Gehäuse Mittel zum Antrieb des Werkzeugs aufnimmt und außen ein Schaltelement trägt. Diese als langes Gartengerät ausgestalteten Handwerkzeugmaschinen ragen allerdings in Arbeitsposition mit ihren vorderen Abknickungen über die vordere haltende Bedienhand hinaus, so dass diese nicht als Handgriff nutzbar sind.From EP-A-0657255 and EP-A-0653364 generic hand tool machines are known, with elongated housing with the housing main part angled arranged, rotating tool, wherein the housing receives means for driving the tool and outside carries a switching element. However, these designed as a long garden tool hand tool machines protrude into working position with their front kinks on the front holding the operator out, so that they are not usable as a handle.
Es sind als Handwerkzeugmaschinen ausgestaltete Bürsten mit vielfältigen, insbesondere stabartigen Gehäuseformen bekannt, die sich vor allem hinsichtlich ihres Antriebs und ihrer Arbeitswirkung unterscheiden und bei denen die Handhabbarkeit bisher zweitrangig war.There are designed as a hand tool brushes with various, especially rod-like housing forms, which differ mainly in terms of their drive and their work and in which the handling was previously of secondary importance.
Es sind auch Winkelschleifer mit etwa rechtwinklig zur Gehäuseachse abgewinkelt angeordnetem, rotierendem Werkzeug bekannt, das auch ein einspannbares Bürstenwerkzeug sein kann.There are also angle grinder with approximately at right angles to the housing axis angled arranged, rotating tool known, which may also be a einspannbares brush tool.
Bei Winkelschleifern und auch bei Handwerkzeugmaschinen mit pistolenförmigem Gehäuse zum Halten und Führen mit nur einer Hand läßt die Handlichkeit dann zu wünschen übrig, wenn Zweihandbedienung mit hohen Haltekräften erforderlich ist, wie z.B. beim Reinigen hartnäckig verschmutzter Teile mit einem Winkelschleifer oder einer Handbohrmaschine mit eingesetztem Bürstenwerkzeug.With angle grinders and also with hand tool machines with pistol-shaped housing for holding and guiding with only one hand, the handiness leaves much to be desired when two-handed operation with high holding forces is required, such as when cleaning stubbornly soiled parts an angle grinder or a hand drill with inserted brush tool.
Die erfindungsgemäße Handwerkzeugmaschine mit den kennzeichnenden Merkmalen des Anspruchs 1 ist gegenüber bekannten Handwerkzeugmaschinen deutlich besser handhabbar, insbesondere beim beidhändigen Führen mit hoher Bedienkraft mit eingesetztem Bürstenwerkzeug, weil durch die doppelt abgeknickte Anordnung der Gehäuseenden diese derart sicher in den Händen des Bedienenden einspannbar sind, daß dies in vielfältigen Haltepositionen ein besonders effektives Führen und Arbeiten gewährleistet.The hand tool of the invention with the characterizing features of claim 1 is compared to known hand tool significantly easier to handle, especially when ambidextrous guiding with high operating force with inserted brush tool, because by the doubly bent arrangement of the housing ends they are so securely clamped in the hands of the operator that this ensures a very effective guiding and working in various holding positions.
Durch die kennzeichnenden Merkmale des Anspruchs 1 ist eine besonders gute Handhabbarkeit bei besonders vielen unterschiedlichen Haltepositionen der Hände des Bedienenden sowohl bei Einhand- als auch Zweihandbedienung gesichert.By the characterizing features of claim 1, a particularly good handling in a particularly many different holding positions of the hands of the operator is secured both in one-handed and two-handed operation.
Dadurch, daß der abgeknickte, das Werkzeug aufnehmende Bereich des Gehäuses an der Abknickung eine Taillierung aufweist, ist den Fingern der Bedienhände ein besonders sicherer, definierter Halt gegeben.Characterized in that the bent, the tool receiving portion of the housing at the bend has a sidecut, the fingers of the operating hands are given a particularly secure, defined hold.
Dadurch, daß das Gehäuse im Bereich der Abknickung einen zumindest teilweise kugeligen Bereich aufweist, haben die Bedienhände einen großflächig anliegenden, bequemen Halt.Characterized in that the housing in the region of the bend has an at least partially spherical region, the operating hands have a large-scale fitting, comfortable grip.
Dadurch, daß seitlich am kugeligen Bereich, insbesondere an je einer Gehäuseschale je ein seitlicher Einzug angeordnet ist, wird die Griffsicherheit am Gehäuse weiter verbessert, wobei der Ringwulst an dem das Werkzeug aufnehmenden, abgeknickten Bereich des Gehäuses nahe der Werkzeugaufnahme ein ungewolltes Berühren des Bürstenwerkzeugs durch die Bedienhand verhindert und die Arbeitssicherheit verbessert.Characterized in that the lateral side of the spherical area, in particular on each housing shell is arranged a lateral indentation, the grip on the housing is further improved, wherein the annular bead on the tool receiving, bent portion of the housing near the tool holder unwanted touching the brush tool by prevents the operator's hand and improves work safety.
Dadurch, daß die Kontur der Taillierung in den Ringwulst abgerundet übergeht, ist die Handhabung besonders bequem.The fact that the contour of the sidecut merges into the annular bead rounded, handling is particularly convenient.
Dadurch, daß die Handwerkzeugmaschine eine überrastbare Spanneinrichtung für auswechselbare Bürstenwerkzeuge unterschiedlicher Größe und Form aufweist, ist ein universeller Einsatz bei schnellem Bürstenwechsel gesichert.Characterized in that the power tool has a snap-on clamping device for replaceable brushes of different sizes and shapes, a universal use with rapid brush replacement is secured.
Dadurch, daß die Spanneinrichtung mittels einer Taste lösbar ist, ist der Werkzeugwechsel schnell und bequem möglich.The fact that the clamping device is releasable by means of a button, the tool change is quick and easy.
Dadurch, daß die Taste aus einem Bereich des Ringwulsts gebildet wird, ist sie besonder leicht von der Hand des Bedienenden erreichbar.Characterized in that the key is formed from a region of the annular bead, it is particularly easy to reach by the hand of the operator.
Dadurch, daß das Gehäuse in Schalenbauweise hergestellt ist, ist das beidenends abgeknickte Gehäuse verwindungs- und biegesteifer und leichter montierbar als in Topfbauweise.The fact that the housing is made in shell construction, the both ends kinked housing torsion and bending resistance and easier to install than in pot construction.
