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.
