ABSTRACT:
A vibration-damping control handle connectable to the shaft portion of a portable power tool, such as a flexible line trimmer or the like, has an elongated, axially tapered body which coaxially circumscribes the shaft and has an operator handgrip section secured thereto. A first end portion of the body is spaced laterally outwardly from the shaft and is interlocked with a free end portion of a resilient damping member which circumscribes the shaft and is secured to a clamp member releasably locked on the shaft. The opposite end of the handle body is connected to the shaft in a slip-fit relationship therewith so that the body may be laterally pivoted or flexed relative to the shaft against the resilient resistance of the free end portion of the damping member which may be a coiled spring or an annular elastomeric element. In alternate embodiments of the handle the damping member clamp is deleted, so that the damping member is in a slip-fit engagement with the shaft, and is replaced with a specially designed pivot clamp secured to the shaft at the opposite end of the handle body and interlocked with such opposite handle body end. The pivot clamp precludes appreciable axial or rotational movement of the handle body relative to the shaft, but permits the body to be laterally pivoted about its connection to the pivot clamp.
