Abstract:
1. A vibration-decoupling arrangement for supporting a percussion unit in a hand-held percussion power tool, the arrangement comprising a spring ( 4 ) arranged between the percussion unit ( 2 ) and a tool housing ( 3 ) and preloaded against an engagement point (P) in the housing ( 3 ) for preventing vibrations of the percussion unit ( 2 ) from being transmitted to the housing ( 3 ), and axial guide means for supporting the percussion unit ( 2 ) in the housing ( 3 ) for a limited axial displacement therein and including two axially spaced, flexurally deformable, articulated arms ( 5 a , 5 b ) secured in the housing ( 3 ) with a possibility of a limited axial displacement and without slip motion relative to the housing ( 3 ), wherein the articulated arms ( 5 a , 5 b ) are directly secured to the percussion unit ( 2 ) without any slip motion relative thereto.
