Abstract

Ein Handwerkzeuggerät (2), das im Betrieb Vibrationen erzeugt, wie insbesondere ein elektrischer Bohrhammer, weist eine sich in eine Horizontalrichtung (Z) erstreckende Werkzeugspindel (10) und ein die Werkzeugspindel (10) zumindest teilweise aufnehmendes Hauptgehäuse (4) auf, das eine Gehäusemittelebene (E) festlegt, entlang der die Horizontalrichtung (Z) und eine zu dieser senkrecht stehenden Vertikalrichtung (Y) gerichtet sind und zu der eine Lateralrichtung (X) des Handwerkzeuggerätes (2) senkrecht steht. Ferner weist das Handwerkzeuggerät (2) ein Griffgehäuse (16) auf, das unter lateraler Zwischenlage eines lateralen Vibrationsminderungselementes (40a; 56a) am Hauptgehäuse (4) abgestützt ist. Es ist vorgesehen, dass das Griffgehäuse (16) zudem sowohl unter horizontaler Zwischenlage eines horizontalen Vibrationsminderungselementes (40c; 56c) als auch unter vertikaler Zwischenlage eines vertikalen Vibrationsminderungselementes (40b; 56b) am Hauptgehäuse (4) abgestützt ist.

A hand tool (2), which generates vibrations during operation, in particular an electric rotary hammer, has a tool spindle (10) extending in a horizontal direction (Z) and a main housing (4) at least partially accommodating the tool spindle (10) Housing mean plane (E) determines along which the horizontal direction (Z) and a perpendicular to this vertical direction (Y) are directed and to which a lateral direction (X) of the power tool (2) is perpendicular. Furthermore, the hand tool device (2) has a handle housing (16) which is supported on the main housing (4) with a lateral intermediate position of a lateral vibration-reducing element (40a; 56a). It is also provided that the handle housing (16) is supported on the main housing (4) both under the horizontal intermediate position of a horizontal vibration-reducing element (40c; 56c) and under the vertical intermediate position of a vertical vibration-reducing element (40b; 56b).
