ABSTRACT:
A filament trimmer comprises a lower housing, an upper handle and a single handle tube connecting the two together to form a completed trimmer. The handle tube has approximately the same length as the length of the lower housing, and the upper handle has approximately the same width as the lower housing, to allow the three-part construction of the trimmer to be packaged in a box of minimum size. The upper end of the lower housing has an S-shaped cord channel, with an adjacent open chamber or space next to and below the cord channel, such that the electrical cord passing downwardly into the lower housing from the handle tube will naturally form a downwardly protruding loop that is easily received in the lower housing when the handle tube is pushed down into the lower housing during assembly. Finally, an extension cord lock is provided on the upper handle comprising an opening in the hand grip forming members of the handle that leads into the hand grip space along with an integral hook that is molded in the interior of the hand grip space by being integrally formed on one of the hand grip forming members. A doubled over portion of the extension cord is pushed through the opening and hooked or looped over the hook to comprise the cord lock.
