Abstract

Ein Handwerkzeuggerät (11) weist ein Aussengehäuse (12), einen Antrieb (13), ein Schlagwerk (14) und zwei vibrationsgedämpfte Handgriffe (21) auf, die jeweils ein Tragelement (22), eine Längsachse (23) und einen Lagerabschnitt (24) an einem ersten Endbereich (25) aufweisen. Weiter sind senkrecht zur Längsachse (23) des Handgriffs (21) verlaufende Handgriffbefestigungsachsen (30) vorgesehen, die jeweils von dem Lagerabschnitt (24) eines Handgriffs (21) umfasst sind. Zwischen dem Lagerabschnitt (24) des Handgriffs (21) und der Handgriffbefestigungsachse (30) ist eine Dämpfhülse (31) aus einem elastischen Material als erstes Dämpfelement vorgesehen. Ein Dämpfkörper (36) als zweites Dämpfelement ist am freien, dem ersten Endbereich (25) des Handgriffs (21) gegenüberliegenden Ende (26) vorgesehen, wobei der Dämpfkörper (36) bezogen auf die Längsachse (23) des Handgriffs (21) eine Erstreckung in radialer Richtung aufweist, die grösser als die entsprechende Erstreckung des Handgriffs (21) an dessen freien Ende (26) ist.

A hand tool (11) has an outer housing (12), a drive (13), a percussion mechanism (14) and two vibration-damped handles (21), each having a support element (22), a longitudinal axis (23) and a bearing portion (24 ) at a first end portion (25). Further, perpendicular to the longitudinal axis (23) of the handle (21) extending handle mounting axes (30) are provided, each of the bearing portion (24) of a handle (21) are included. Between the bearing portion (24) of the handle (21) and the handle mounting axis (30) a damping sleeve (31) made of an elastic material is provided as a first damping element. A damping body (36) as the second damping element is provided at the free end (26) opposite the first end region (25) of the handle (21), wherein the damping body (36) has an extension relative to the longitudinal axis (23) of the handle (21) in the radial direction, which is greater than the corresponding extent of the handle (21) at its free end (26).
