  • Anti-vibratory handle for percussive and other reciprocating tools
    Publication number: 20070107165
    Abstract: Described is an anti-vibratory handle for installation on a reciprocating tool supplied with a pressurized fluid and producing vibrations in the direction of an axis of reciprocation of the tool. The anti-vibratory handle comprises a stationary portion mounted to a body of the tool, a mobile portion comprising a hand-grip member and an articulation between the stationary and mobile portions. This articulation comprises a pivot assembly interconnecting the stationary and mobile portions, the pivot assembly defines a pivot axis substantially perpendicular to the tool reciprocation axis, and the hand-grip member of the mobile portion is spaced apart from both the pivot axis and the tool reciprocation axis. The articulation also comprises a resilient vibration-damping assembly interposed between the stationary and mobile portions to avoid transmission of vibrations through the articulation.
