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.

Dependent claims

A plastic handle member for manually guided power chain saws, said handle member comprising:

a single piece of plastic including a front handle having a lower profiled bar, a rear control handle and a support member disposed between the front handle and the rear control handle to connect said front handle and said control handle;
said front handle being at least partially tubular and serving for holding a separate motor unit;
said rear control handle includes an upper portion for accommodating components for controlling a chain saw;
said front handle, said support member and said lower profiled bar singularly forming a polygon that absorbs load and vibrational forces;
support means respectively disposed in said front handle, in said lower profiled bar, and in said support member;
and vibration-damping elements provided in said support means such that said vibration-damping elements are disposed between a housing of said motor unit and those parts of said handle member in which said support means are disposed to thereby effect said absorption of said load and vibrational forces.
