Abstract

A vibration damper for a vibrational mechanical body, such as a chain saw, mower, or motorcycle, which is a source of vibration, comprises a support 2, such as an arm of the vibrational body for manipulation, a cylindrical grip 3 mounted on the support, and a vibration-damping means consisting of a pair of coiled springs 4,4' having a row of small and large coiled portions and disposed between the support 2 and the rigid grip 3, with each of the small coiled portions being engaged with and supported by the support and each large coiled portion by the inner surface of the grip, whereby the vibration transmitted from the vibrational body to the support is absorbed by the vibration-damping coiled spring to control or lessen the vibration transmission to the grip. Numerous embodiments, some including rubber 13 in parallel or in series, or encasing the coil springs. One, Figs 25-27, not shown, has two pairs of coil springs in series, with an intermediate tubular member between the pairs. <IMAGE>
