Patent ID: 8100745

Claim:
A power tool comprising: a tool body, wherein the tool body is subject to vibration during operation of the power tool; a handle adapted to be grasped by an operator of the power tool for controlling the motion of the power tool; and at least one semi-rigid, resilient coupling member, each coupling member including a first end coupled to the tool body and a second end coupled to the handle and a longitudinal axis between the first end and the second end, wherein the at least one coupling member is configured to inhibit the transmission of vibration from the tool body to the operator grasping the handle during operation of the power tool, wherein during operation of the power tool the tool body vibrates at a primary vibration frequency, and wherein a natural frequency of a first-order transverse vibrational mode of the handle when grasped by a hand of the operator is lower than the primary vibration frequency, and wherein the at least one coupling member comprises a resilient material, such that the collective response of the coupling members to vibration can be characterized by a collective spring constant and wherein the square root of the collective spring constant divided by the mass of the handle is less than a primary vibration frequency at which the tool body vibrates during operation of the power tool.
