Air conducting convertor for string trimmer

摘要

An air conducting convertor for a powered string trimmer is disclosed, wherein the trimmer to be converted has a power shaft with opposing proximal and distal ends, a power-providing unit disposed upon the proximal end thereof, and a string head coupling disposed on the distal end thereof. The converting apparatus includes a collar bracket adjacent the distal end of the trimmer, and struts projecting from the collar bracket and supporting a surrounding fan shroud. A fan having blades pitched to move air distally through the shroud is coupled with the trimmer's standard trimmer head coupling. A curved, rotatable air duct with interior baffle plates is engaged with the shroud and projects distally therefrom. A debris bag is suspended from the trimmer's shaft has a collector portion which is engaged with the proximal rim of the fan shroud, so when a fan pitched to move air proximally is mounted on the trimmer, the apparatus is able to act as a vacuum. A caster supports the apparatus above a surface in both the blowing and vacuum modes.
