Landscaping Tool for Edging and Grading

Abstract

The present invention is directed to a rigid, blade-shaped landscaping tool for defining and maintaining a well-defined boundary between a garden or soil bed and an adjacent natural or man-made ground surface. The tool generally comprising a vertical cutter, a horizontal cultivator, a grader flange and a handle mount disposed on the top edge of the blade. In particular, the landscaping function of the tool can be accomplished by physically drawing the tool along the adjacent natural or man-made ground surface whereby the vertical cutter and an associated horizontal cultivator sever plant growth and/or dislodge soil which are then physically graded away from the plane of the vertical cutter and away from the adjacent ground surface toward the soil bed to create the desired, well-defined edge and/or boundary between the soil bed and the adjacent ground surface.

[0022] In order that the manner in which the above recited and other features and advantages of the present invention are obtained, a more particular description of the invention will be rendered by reference to specific embodiments thereof, which are illustrated in the appended drawings. Understanding that the drawings depict only typical embodiments of the present invention and are not, therefore, to be considered as limiting the scope of the invention, the present invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:

[0023] FIG. 1 illustrates a top perspective view of one embodiment of the landscaping tool of the present invention;

[0024] FIG. 2 illustrates a side perspective view of one embodiment of the landscaping tool of the present invention;

[0025] FIG. 3 illustrates perspective view from the first end of the blade toward the second end of the blade of one embodiment of the landscaping tool of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The present invention relates to substantially low-profile landscaping tool used to create a desired border between a soil bed and an adjacent surface. The adjacent surface may be a lawn, other walking path, sidewalk or curb. The new landscaping tool permits the user to simultaneously make a vertical cut of the lawn, a horizontal cut or cultivation of soil at the base of and contiguous with the vertical cut, the horizontal cut made in the soil in the direction of the garden bed, and grading of the cut or cultivated soil from the apex of the vertical and horizontal cuts in the direction of the garden bed. In this way a well defined border can be created and/or maintained between the chosen soil bed and adjacent surface.

[0027] FIG. 1 shows a top perspective view of one embodiment of the landscaping tool 10 of the present invention. Tool 10 comprises a low-profile, substantially vertical blade 20 and an appended low-profile, substantially horizontal cultivator 30.

[0028] As shown in FIGS. 1 and 2, the blade 20 comprises a first end 21, a second end 22, a top edge 23, a bottom edge 24, a front or garden side 25 and a back or lawn/structure side 26. The blade comprises a substantially vertical cutting edge 27 at the first end 21 and a grader 28 at the second end 22. If desired, the blade can be oriented a desired number of degrees from vertical.

[0029] As shown in FIGS. 1-3, grader 28 is defined by forming the second end 22 of blade 20 such that second end 22 of blade 20 departs from the plane 29 (shown in dotted lines) of the rest of blade 20 in an arcing manner toward the garden side 25 of the blade. Grader 28 is disposed vertically so as to direct cultivated soil toward the soil bed away from the adjacent surface. The substantially vertical orientation of cultivator 28 avoids soil being lifted up and/or over cultivator 28 in the direction of the adjacent surface thereby depositing cultivated soil and any other cuttings from cutting edge 27, if any, to the soil bed not on the adjacent lawn, walkway, curb or sidewalk.

[0030] The top edge 23 of the blade comprises a means 40 for receiving a handle 41. Means for receiving a handle 41 is any conventional structure known by those of skill in the art designed to receive a handle such as a pole handle common to landscaping tools which are grasped by the user to direct the use of the tool.

[0031] The bottom edge 24 of blade 20 hosts a low profile, substantially horizontal cultivator 30 disposed along the bottom edge of the blade at substantially a right angle to blade 20 as shown in FIG. 3. The cultivator comprises a leading edge 31 and a boundary edge 32, the cultivator having a proximal end 33 attached to the blade and a distal end 34 extending away from the blade on the garden side of blade 20 in the direction of the soil bed. In the preferred embodiment, cultivator 30 is angled in the direction of grader 28 as shown by angle A in FIG. 1, angle A being greater than ninety degrees. An angled cultivator 30 and leading edge 31 along leading edge 31 and boundary edge 32 permit cultivator 30 to slice through the soil.

[0032] In a preferred embodiment, cultivator 30 is disposed along bottom edge 24 of blade 20 at a position adjacent and contiguous to first end 21 to provide a juncture 50 where cutting edge 27 of blade 20 joins in a contiguous manner with leading edge 31 of cultivator 30. This contiguous juncture provides a number of advantages. The contiguous juncture creates a well-defined boundary between the soil bed and the adjacent surface at juncture 50. A contiguous juncture and the angled nature of leading edge 31 of cultivator 30 lessens the amount of exertion of the user.

[0033] Cutting edge 27, leading edge 31 and boundary edge 32 are preferably configured with a beveled or ramped surface 35 to facilitate cutting and cultivating and to minimize drag and friction as tool 10 trims adjacent lawn and is drawn through soil. Surface 35 also promotes the retention of cultivator 30 in the soil as the user pulls tool 10 through soil. The substantially horizontal orientation of cultivator 30 reduces the drag and friction between tool 10 and the soil when tool 10 is drawn through soil.

[0034] In use, tool 10 is placed with end 21 of blade 20 against a surface such as a lawn edge, walkway boundary or vertical side of a sidewalk or curb. The user draws or pulls tool 10 in the direction shown by arrow B in FIG. 1 along the adjacent surface. Tool 10 is used by physically drawing the tool along the adjacent natural or man-made ground surface whereby the vertical cutter and an associated horizontal cultivator sever plant growth and/or dislodge soil which are then physically graded away from the plane of the vertical cutter and away from the adjacent ground surface toward the soil bed to create the desired, well-defined edge and/or boundary between the soil bed and the adjacent ground surface.

[0035] For example, when maintaining a lawn edge, drawing tool 10 in the direction of arrow B performs a number of landscaping operations at the same time. The user manually directs cutting edge 27 along or into the lawn edge thereby maintaining or trimming the lawn edge as desired. At the same time the user manually positions cultivator 30 at the desired depth in the soil and by pulling leading edge 31 and boundary edge 32 through the soil at the desired depth soil is cultivated. At the same time, a well-defined boundary is formed between the soil bed and the lawn by juncture 50. At the same time the cultivated soil is graded back into the soil bed by grader 28. In this manner, the user is able to selectively define and/or maintain the desired lawn edge and boundary with minimal effort due to the low-profile nature of landscaping tool 10. The same landscaping technique can be used between a sidewalk and a garden bed where end 21 of blade 20 rests against the vertical side of the sidewalk .

[0036] Thus, as discussed herein, the embodiments of the present invention embrace FIGS. 1-3 and equivalents thereof.

[0037] The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
