  • Vibration-decoupling arrangement for supporting a percussion unit in a hand-held percussion power tool
    Patent number: 6962211
    Abstract: A vibration-decoupling arrangement for supporting a percussion unit (2) in a hand-held percussion power tool includes 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 two axially spaced, flexurally deformable, articulated arms (5a, 5b) secured in the housing (3) for supporting the percussion unit (2) in the housing (3), with the arms (5a, 5b) being secured in the housing (3) with a possibility of a limited axial displacement and without any slip motion relative to the housing.
    Type: Grant
