Patent ID: 8511658

Claim:
A hand-held power tool, comprising: a sub-assembly that vibrates along a vibration axis; a handle sub-assembly; and an antivibration element for vibrationally decoupling the handle sub-assembly from the vibrating sub-assembly and having a coil spring formed of a spring wire and oriented along the vibration axis, and a threaded plug provided with an outer thread longitudinally extending therealong, the coil spring having a plurality of windings extending along a preload region and screwed on the outer thread under an axial compressive preload, the outer thread having a between-flight width greater than a diameter of the spring wire of which the coil spring is formed, wherein the coil spring has an increasing spring rate curve thoughout an entirety of the spring rate curve, wherein the spring rate curve has a first section and a second section following the first section, the second section increasing less steeply than the first section, and wherein the spring rate curve has a third section following the second section and increasing more steeply than the second section.
