The present subject matter relates generally to trimmer devices, such as landscape trimmers, and more particularly to a trimmer head assembly for a trimmer.
Landscape trimmers are typically useful for cutting grass or weeds, and may be used for edging around trees, fences, landscape borders, etc. Conventional landscape trimmers are often referred to as string trimmers and include an elongated shaft with a rotating head attached to one end of the elongated shaft. A spool or segment of monofilament string is often fixed to the rotating head in such embodiments. Thus, the monofilament string may rotate with the rotating head and act as cutting element. Recently, trimmers having solid, non-string cutting elements (e.g., blades) attached to the rotating head have been utilized.
There can be various shortcomings for existing trimmers. For instance, when selecting or buying a trimmer, a user is often forced to decide whether string cutting elements or solid blades are preferred. If a user later wishes to use a different cutting element, that user must often purchase a completely new rotating head or landscape trimmer. Moreover, regardless of what type of cutting element is chosen, the cutting elements will eventually need to be replaced. This typically requires significant disassembly of the rotating head. For instance, at least a portion of the rotating head must be removed from the elongated shaft before cutting elements can be replaced and the rotating head is returned to the elongated shaft. These can all be cumbersome sources of frustration for users.
A full and enabling disclosure of the present invention, including the best mode thereof, directed to one of ordinary skill in the art, is set forth in the specification, which makes reference to the appended figures.
FIG. 1 provides a perspective view of a landscape trimmer according to exemplary embodiments of the present disclosure.
FIG. 2 provides a top perspective view of a trimmer head for a landscape trimmer according to exemplary embodiments of the present disclosure.
Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
As used herein, the term “or” is generally intended to be inclusive (i.e., “A or B” is intended to mean “A or B or both”). The terms “first,” “second,” and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components.
Turning now to the figures, FIGS. 1 through 8 provide various views illustrating a trimmer head 110 for a landscape trimmer 100, according to exemplary embodiments of the present disclosure.
