Abstract

A trimmer head or trimmer head assembly for a trimmer is provided herein. The trimmer head may include a base plate defining an axial direction, a pivot head, and a blade retainer. The pivot head maybe attached to the base plate. The blade retainer may include a radial arm rotatably mounted to the base plate to rotate relative to the base plate between a first position at which the radial arm iscircumferentially aligned with the pivot head and a second position at which the radial arm is circumferentially spaced apart from the pivot head.

Description

technical field [0001] The disclosed subject matter generally relates to trimmer devices, such as landscape trimmers, and more particularly, to trimmer head assemblies for trimmers. Background technique [0002] Landscape trimmers are commonly used to cut grass or weeds, and can be used to trim around trees, fences, landscape borders, and more. Traditional landscape trimmers are often referred to as string trimmers and include an elongated shaft with a swivel head attached to one end of the elongated shaft. In such embodiments, a spool of monofilament rope or a length of monofilament rope is typically fixed to the spinning head. Thus, the monofilament rope can rotate together with the swivel head and act as a cutting element. More recently, trimmers having a sturdy, cordless cutting element (eg, blade) attached to a rotating head have been used. [0003] Various disadvantages may exist with existing trimmers. For example, when selecting or purchasing a trimmer, users are...
