Description

FIELD OF THE INVENTION

The present disclosure relates to a grass trimmer apparatus. Specifically, the present disclosure relates to an adjustable grass trimmer attachment, for trimming in tight spaces.

BACKGROUND

Powered, handheld implements such as weed trimmers, lawn edger's, brush cutters, etc., are examples of tools normally held by both hands during use. These implements and others like them generally include a longitudinal shaft with a motor or other power source mounted on the rear portion of the shaft and a cutting head or other energetic device, driven or energized by the power source, mounted on the front portion of the shaft. Lawn mowers, and grass trimmers are often used to cut grass or weeds in wide open areas, where there is lots of land, and areas to maneuver. A conventional trimmer comprises of a motorized mobile device with at least two wheels, with elongated handles extending upward for the user to push and pull the trimmer along grassy open areas. Accordingly, during operation the trimmer is housed under the mobile device. The trimmer comprises of a head that rotates and the trimmer line cuts weeds, grass and other vegetation. The operator of the weed trimmer typically grips the handles provided on a shaft to hold the trimmer head over the weeds, grass or other vegetation being cut. This, however, can result in fatigue to the operator, particularly during prolonged periods of operating the weed trimmer. Additionally, the large size of the conventional trimmer makes it difficult for a user to cut a straight line alone a fixed structure, along tight quarters, or in otherwise tight spaces. Furthermore, obtaining small, accurate movements of the mobile device in these tight spaces or when using the trimmer for tilted cutting on uneven or sloped terrain can be prohibitively difficult using a conventional trimmer. Accordingly, improvements to the trimmer stability, and handle, along with configurations of these and other implements held in a similar manner are desirable.

Embodiments of the invention, on the other hand, provide significant advantages while overcoming the above-described and other disadvantages, as will now be described.
