Abstract
A plastic handle member for manually guided power chain saws is provided. The handle member comprises a one-piece, at least partially tubular, front handle for holding a separate motor unit, the front handle being provided with a lower profiled bar. A rear control handle is provided having an upper portion for accommodating components for controlling a chain saw. A support member is disposed between the front handle and the control handle for interconnecting them. The front handle, the rear control handle, and the support member comprise a one-piece plastic body made of a single material and in conjunction with the lowered profile bar form a self-contained force polygon that absorbs load and vibrational forces by means of vibration-damping elements provided in supports disposed between the handle member and a housing of the separate motor unit for holding the housing of the motor unit.
