Description

Die Erfindung bezeichnet eine Griffausführung eines Elektrohandwerkzeuggerätes wie einer Bohrmaschine, eines Kombihammers, Bohrschraubers usw., welches vorteilhaft akkubetrieben ist.The invention relates to a handle design of an electric hand tool device such as one Drill, a combi hammer, screwdriver, etc., which is advantageous is battery operated.

Derartige, sich längs einer Gerätelängsachse erstreckende, Elektrohandwerkzeuggeräte weisen am vorderen Teil eine von einem Elektroantrieb angetriebene Werkzeugaufnahme und am hinteren Teil einen radial von der Gerätelängsachse auskragenden Handgriff auf, welcher üblicherweise Steuerelemente beinhaltet und hauptsächlich zur Aufbringung axialer Kräfte durch den Nutzer dient. Zur Aufnahme eines Drehmoments ist bspw. nach der US5881823 ein optionaler zweiter, radial von der Gerätelängsachse auskragender Zusatzhandgriff drehschwenkbar feststellbar vorhanden.Such electric hand tool devices, which extend along a longitudinal axis of the device have a tool holder driven by an electric drive on the front part and on the rear part a handle projecting radially from the longitudinal axis of the device, which usually contains control elements and mainly for the application of axial Forces served by the user. To take up a torque, for example, after US5881823 an optional second, projecting radially from the longitudinal axis of the device Additional handle can be swiveled and locked.

Ein bspw. nach US6168881 zur axialen Mitte versetzter, T-förmig angeordneter Handgriff eignet sich durch den axial mittigen Schwerpunkt und somit geringe Handmomente für eine überwiegend horizontale Nutzung des Elektrohandwerkzeuggerätes, wohingegen ein bspw. nach US5343961 endständig angeordneter, pistolenförmiger Handgriff für überwiegend vertikale Nutzung des Elektrohandwerkzeuggerätes geeignet ist.A, for example, according to US6168881 offset to the axial center, T-shaped handle is suitable for one due to the axially central center of gravity and thus low hand moments predominantly horizontal use of the electric hand tool device, whereas a e.g. according to US5343961 terminally arranged, pistol-shaped handle for predominantly vertical use of the electric hand tool device is suitable.

Akkubetriebene Elektrohandwerkzeuggeräte bspw. nach der US4871629 weisen den schweren Akkumulator üblicherweise im radialen Endbereich des Handgriffs auf, um damit ein hohes Rotationsträgheitsmoment zu erzielen. Durch die hohe Masse des Akkumulators muss die Griffkonstruktion hinreichend formstabil mit dem restlichen Werkzeuggehäuse verbunden sein, wodurch ein technologischer Zusatzaufwand entsteht.Battery-operated electrical hand tool devices, for example according to US4871629, have the heavy accumulator usually in the radial end region of the handle in order to to achieve a high rotational moment of inertia. Due to the high mass of the battery the handle construction must be sufficiently dimensionally stable with the rest of the tool housing be connected, which creates an additional technological effort.

Nach der DE2917475 weist ein Elektrohandwerkzeuggerät am hinteren Ende der Gerätelängsachse einen geschlossen bügelförmigen Handgriff mit einem Steuerelement auf.According to DE2917475, an electric hand tool device has at the rear end of the Device longitudinal axis on a closed bow-shaped handle with a control.

Nach der US5813805 weist ein Elektrohandwerkzeuggerät einen längs der Gerätelängsachse verlaufenden, geschlossenen Griffbügel auf. Dieser Griffbügel bildet keinen radial von der Gerätelängsachse auskragenden Handgriff, sondern ausschliesslich einen längs der Gerätelängsachse orientierten Handgriff aus. According to US5813805, an electric hand tool device has a along Device handle axis running, closed handlebar. This handle bar forms no handle protruding radially from the device's longitudinal axis, but exclusively a handle that is oriented along the longitudinal axis of the device.

Nach der DE19745308A1 weist eine Bohrmaschine einen radial von der Gerätelängsachse auskragenden pistolenförmigen Handgriff und einen zweiten, radial von der Gerätelängsachse auskragenden Zusatzhandgriff auf, welcher axial vorderseitig durch einen offenen Schutzbügel geschützt ist.According to DE19745308A1, a drill has a radially from the longitudinal axis of the device cantilevered pistol-shaped handle and a second, radially from the Device handle cantilevered additional handle, which is axially on the front by a open guard is protected.

Nach der EP878272 bildet der radial von der Gerätelängsachse auskragende Handgriff gemeinsam mit einem axial vorn angeordneten, radial von der Gerätelängsachse auskragenden Motorgehäuse einen geschlossenen Schutzbügel, wobei das Motorgehäuse für einen Zusatzhandgriff zu umfangreich ist.According to EP878272, the handle protrudes radially from the longitudinal axis of the device together with an axially front, radially from the longitudinal axis of the device cantilevered motor housing a closed protective bracket, the motor housing is too extensive for an additional handle.

Nach der DE3224141 weist ein radial von der Gerätelängsachse auskragender Handgriff einen geschlossen übergreifenden Schutzbügel auf, welcher für einen Zusatzhandgriff zu dünn ausgebildet und für den zweihändigen Betrieb zu gering vom Handgriff axial beabstandet ist.According to DE3224141, a handle protrudes radially from the longitudinal axis of the device a closed overlapping protective bar, which for an additional handle thin and too small for two-handed operation axially is spaced.

Die Aufgabe besteht in der Realisierung einer kompakten und technologisch einfachen zweihändigen Griffausführung eines Elektrohandwerkzeuggerätes. Ein weiterer Aspekt besteht in der formstabilen Verbindung eines Akkumulatorgehäuses mit dem Gerätegehäuse.The task is to realize a compact and technologically simple two-handed handle design of an electric hand tool device. Another aspect consists in the dimensionally stable connection of an accumulator housing with the Device housing.
