Abstract
A chain saw in which a body having an engine, carburetor and throttle rod and a handle frame on which is located a fitting mounting a trigger are connected with each other though vibration damping members. The trigger is provided with a plurality of bends between a contact part and a finger grip so as to have a predetermined spring effect. The contact part is arranged in opposition to the end of the throttle rod and spaced from it. As contact part abuts the rod and the chain saw is flex the resilient spring effect from the bends reduces the vibration transmitted to the handle.
Claims3
A chain saw comprising a body housing an internal combustion engine, a carburetor and a throttle rod for controlling the carburetor, a handle frame having a fitting for mounting a trigger mechanism for actuating said throttle rod, and vibration damping means for resiliently connecting said body and said fitting, said trigger mechanism comprising a pivotal finger grip, a contact part for abutting an end of the throttle rod on pivoting of said finger grip and a plurality of yieldable bends arranged between said contact part and said finger grip so as to provide a predetermined spring bias therebetween.
