(11) The following description is not to be taken in a limiting sense, but is made merely for the purpose of describing the general principles of exemplary embodiments. Reference throughout this specification to one embodiment, an embodiment, or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases in one embodiment, in an embodiment, and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.

(12) FIG. 1 depicts an apparatus for an adjustable grass trimmer 100. The apparatus includes an elongated shaft 102 comprising a first end and a second end. The first end comprises of a handle for an operator to maneuver the device, and control the direction of the trimmer 100. The second end is utilized as the supporting end, that is configured to support the supporting device. The supporting device is configured to support and stabilize the trimmer 100 that is extended from the elongated portion. The supporting device is configured to maintain the trimmer at a predetermined height, depth, or length respective to the ground or vegetation below it. The supporting device is configured with three support members that are positioned to form a triangular shape, as shown in FIG. 3. Each of the support members 104, 106, 108, 110, 111 are secured at each of their proximal and distal ends to each of the other support members, in order to form the three corners of the triangular shape. At each of the corners, there are securing devices 112a-c selected from one or more of nuts, bolts, washers, or screws, in order to secure each of the support members to the other support members.

(13) The supporting device further comprise of a plurality of wheels 114a-c that are configured to allows the adjustable grass trimmer to be mobile in one or more of a forward direction, a backward direction, or a horizontal direction, as shown in FIG. 2. Each of the plurality of wheels 114a-c can be permanently affixed or removably attached to the supporting device. As the trimmer is operated by an operator, the operator can adjust to or more of the securing devices 112a-c in order to preset a height of the trimmer 118 to ensure the vegetation or grass is cut at a certain level. In addition, the apparatus includes a guard wheel stop affixed to an end of a horizontally extending support member. The horizontally extending support member 106 is configured to secure the plurality of wheels 114a-c on a first end, and secure the guard wheel stop on a second end. The guard wheel stop is configured to contact a fixed structure 120 in order to establish a cutting distance between the trimmer and the fixed structure. Accordingly, this ensures that the trimmer 118 is able to cut a straight line cut at a consistent depth in relation to the fixed structure 120. In addition. A securing member 112 is configured to adjust the depth at a predetermined distance by the operator prior or during operation.

(14) As shown in FIG. 4, in some embodiments, the horizontally extending support member 106 can also secure the trimmer and a debris stopper 116 connected to the trimmer 118. The trimmer 118 can further be electric or gas operated. In some embodiments, the trimmer can be interchangeable and thus be removed from the supporting device in favor of a different trimmer device.

(15) FIG. 5 is an exploded via of the support members. The support members are each configured to form a triangular shape in order to provide support, angle, horizontal extension, and vertical height adjustment to facilitate a trimmer 117 adjustment. The cross bracket 104 is configured to be positioned in parallel and adjacent to the vertical support member 110 in order to allow for the vertical adjustment.

(16) The vertical support member 110 is attached to a base structure 108 that is configured to provide support to the other supporting members 104, and 106 when attached to each other at one or more attachment points. The base structure 108 is further configured to receive two wheels 114b-c that are secured via a securing means such as a screw and bolt mechanism or other securing mechanism. The wheels are positioned to be able to rotate in a 360-degree circumference in order to allow the trimmer to be rotated in one direction or another or at various angles. The base can be a triangular structure, a pentagon structure or another polygon that allows for sufficient support and stability.

(17) There is an additional wheel on the horizontal support member 106, configured to contact a fixed structure. The wheel 114a is configured to roll along the fixed structure, at a horizontal position, maintaining the operator's desired distance from the fixed structure, while also allowing for fluid movement. Each of the supporting members 104, 110, and 106 are configured to be removably attached to each other to form various triangular structures such as an equilateral triangle, an isosceles triangle, or an obtuse triangle relative to the distance from a fixed structure, the height of the vegetation that is being cut by the trimmer, or the angle of the cut needed of the vegetation. The supporting members 104, 106, 110 are attached to each other via a securing bracket that includes a hinge lock 126 mechanism as well as a bolt and screw securing mechanism 124. The bolt and screw mechanism allows for the securing device to be attached to within the pass-through grooves 122 of each of the supporting members 104, 106, 110. The bolt portion passes through the grooves 122 and is securing in the grooves 122 with a bolt that is configured to rotate around the threads of the bolt and be tightened. The hinge lock 126 allows for each of the grooves to be attached to the support shaft as shown in FIG. 1 to FIG. 3. The extending portion of the hinge lock 126 extends out to be loosened from the shaft and closed inward in order to secure lightly around the shaft.

(18) Example embodiments having thus been described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the intended spirit and scope of example embodiments, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.

(19) Although the present invention has been described in terms of various embodiments, it is not intended that the invention be limited to these embodiments. Modification within the spirit of the invention will be apparent to those skilled in the art.

(20) It is additionally noted and anticipated that although the device is shown in its most simple form, various components and aspects of the device may be differently shaped or modified when forming the invention herein.
