DIGGING TOOL SYSTEM

Abstract

A digging tool system provides a combination pickaxe and shovel superior to other digging tools in that it effectively allows a user to both break apart dense or impacted material and to move the material with a single tool. The digging device includes a digging head with a generally triangular blade which is capable of penetrating and moving substrate. The blade has a vertically and horizontally curved face, with a greater depth of curve on one side of the horizontal curvature, and a substrate-piercing tip formed by the apex of the blade which is positioned off-center relative to a handle. The greater depth on one side and the off-center placement of the substrate-piercing tip allow for material to be moved to one side as the digging device is pulled through the material.

DETAILED DESCRIPTION

[0016] As discussed above, embodiments of the present disclosure relate to earth working and more particularly to a digging tool system as used to improve the use of hand tools.

[0017] Generally, the present invention provides a multi-purpose digging tool which is a pickaxe combined with a shovel. It resembles a tilling blade from larger farm equipment but is lighter and more practical as a hand tool. The handle connecting to the head of the digging tool is at a particular angle in relation to the digging head so that driving down into the dirt is very easy, and once the head is in the dirt the leverage on the handle makes it easy to drag the dirt around. The blade has a pointed tip to make penetrating hard ground relatively easy.

[0018] Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-4, various views of a digging tool systems 100. FIG. 1 shows a digging tool system 100 during an in-use condition 150, according to an embodiment of the present disclosure. As illustrated, the digging tool system 100 may include a digging device comprising a digging head 110 having a generally triangular blade 112 capable of penetrating and moving substrate. The generally triangular blade 112 may have a curved face with vertical and horizontal curvature with the horizontal curvature having a greater depth on one side (left or right-hand depending on embodiment).

[0019] The generally triangular blade 112 terminates in an apex having an acute angle forming a substrate-piercing-tip 114 which is positioned off-center relative to a handle 120. The greater horizontal curvature depth on one side and the off-center position of the substrate-piercing-tip 114 allow for substrate to be moved to an opposite-side when the digging head 110 is inserted into and pulled through substrate. The digging device preferably includes an integral handle support frame 116, which has an end cap 118 and at least one elongated support arm 119. The digging device is configured to move a volume of substrate allowing the substrate to be repositioned during a hoeing-digging process.

[0020] FIG. 2 shows a side perspective view of the digging tool systems 100 of FIG. 1, according to an embodiment of the present disclosure. As above, the digging tool system 100 may include a digging device comprising a digging head 110 having a generally triangular blade 112 having a curved face with vertical and horizontal curvature with the horizontal curvature having a greater depth on one side and which terminates in an apex having an acute angle forming a substrate-piercing-tip 114 which is positioned off-center relative to a handle 120. The greater depth and substrate-piercing-tip 114 are positioned off-center on the left-side of the digging head 110 in certain embodiments. The substrate-piercing-tip 114 points generally downward during use and is slope-contoured and occupies a position rearward of a distal end of the handle 120 and nearer a proximal end of the handle 120.

[0021] Referring now to FIG. 3 showing a top perspective view of the digging tool systems 100 of FIG. 1, according to an embodiment of the present disclosure. As above, the digging tool system 100 may include digging device comprising a digging head 110 having a generally triangular blade 112 having a curved face with vertical and horizontal curvature with the horizontal curvature having a greater depth on one side and which terminates in an apex having an acute angle forming a substrate-piercing-tip 114 which is positioned off-center relative to a handle 120. The greater depth and substrate-piercing-tip 114 are positioned off-center on the right-side of the digging head 110 in certain embodiments. The digging head 110 also includes an integral handle support frame 116 which is removably affixed to the handle 120 using fasteners or other suitable means. In an alternate embodiment, the integral handle support frame 116 is removably affixed to the handle 120 using a compression fit. The integral handle support frame 116 includes an end cap 118 that fits over the distal end of the handle 120, with the distal end of the handle 120 being nested within the end cap 118. The integral handle support 116 frame further comprises at least one elongated support arm 119 which extends from the end cap 118 and is adjacent and in physical contact with the handle 120; the handle 120 being parallel to the at least one elongated support arm 119 as nested and contours offset as approaching the proximal end of the handle 120. The handle 120 is made of a material selected from the group consisting of: wood, plastic, fiberglass, carbon fiber, ferrous material, non-ferrous material, and composite material.

[0022] FIG. 4 shows a side perspective view of the digging tool systems 100 of FIG. 1, according to an embodiment of the present disclosure. As above, the digging tool system 100 may include a digging head 110 which comprises a scooped member and is preferably made from a ferrous material. In certain embodiments the digging head 110 includes a titanium edge along one side. According to one embodiment, the digging tool system 100 may be arranged as a kit. The kit may include a digging device and instructions. The instructions may detail functional relationships in relation to the structure of the digging tool system 100 (such that the digging tool system 100 can be used, maintained, or the like, in a preferred manner).

[0023] Referring now to FIG. 5, a flow diagram 550 illustrating a method for using a digging device 500, according to an embodiment of the present disclosure. As illustrated, the a method for using a digging device 500 may include the steps of: providing 501 a digging device, the device including: a digging head having a generally triangular blade with a substrate-piercing-tip, an integral handle support frame, and a handle; gripping 502 the handle so that the substrate-piercing tip may be pointing downward; swinging 503 the digging device downward; plunging 504 the digging device into the substrate; and pulling 505 the digging device toward the user through the substrate. The method of using digging tool systems may further comprise the steps of: scooping 506 the substrate; lifting 507 the digging device; and depositing 508 the substrate to a desired area.

[0024] It should be noted that steps 506, 507, and 508 are optional steps and may not be implemented in all cases. Optional steps of method of use 500 are illustrated using dotted lines in FIG. 5 so as to distinguish them from the other steps of method of use 500. It should also be noted that the steps described in the method of use can be carried out in many different orders according to user preference. The use of step of should not be interpreted as step for, in the claims herein and is not intended to invoke the provisions of 35 U.S.C. 112(f). It should also be noted that, under appropriate circumstances, considering such issues as design preference, user preferences, marketing preferences, cost, structural requirements, available materials, technological advances, etc., other methods for digging tool systems 100 (e.g., different step orders within above-mentioned list, elimination or addition of certain steps, including or excluding certain maintenance steps, etc.), are taught herein.

[0025] The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention. Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientist, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application.
