High strength shovel and trowels

Abstract

Shovels and trowels are formed from metal and plastic for enhanced soil and sand penetration, and for cutting into roots. The shovels and trowels can each have one or more narrow tip teeth edges extending outward from the front end of the blade, the teeth edges each having embossed surface portions for strengthening the blade and disbursing stress during digging applications. The embossed portions can be indented. The embossed portions can be raised. A shovel version can also have foot brakes on both side of the handle above the rear end of the blade, to allow for a stable and safe foot placement.

Description

FIELD OF INVENTION

This invention relates to shovels and trowels, in particular to high strength shovels and trowels formed from metal and plastic for enhanced soil and sand penetration and cutting into roots.

BACKGROUND AND PRIOR ART

Many commercial types of digging and cutting tools have been proposed over the years for penetrating and moving soil and sand. Commercially available digging and cutting tools have included shovels and trowels. Digging and cutting tools are comprised of shovels and trowels and are usually grouped into two primary types. A first type usually includes a relatively flat bottom surface and a second type usually includes upper surface with a generally concave configuration. Particularly with those shovels having a flat surface, sides may be provided extending from the flat surface to prevent the material from falling off the shovel. There are many problems with these types of digging and cutting tools.

One particular problem existing in currently available shovels is their lack of sufficient strength for penetrating rocky soils, hardened soils, soils having significant tree root infestation, as well as grassy covered soils. Often the commercially available shovels have blades that are prone to bending and can often break when the shovel is being used for digging in difficult hardened soils.

In addition to the blade bending and breaking, the tip edge of many commercial shovels can also bend and/or break when being used. A bent tip and/or breakage can result in lost time and possibly an unusable digging tool.

Hence, there exists a need for a high strength shovel having the ability to freely penetrate such hardened soils without bending or breaking. Further, there is a need for a high strength shovel blade that can easily penetrate through grassy soil as well as small to moderate sized trees with many small roots.

Still furthermore, an additional problem with most shovels is their lack of an adequate foot placement surface to rest a user's foot on. Most shovels require the user to to press down on an upper often sharp edge of the shovel blade. This thin blade edge does not allow for a stable foot placement for one's foot to rest on. The currently thin upper edge of the shovel can often result in causing the user's foot to slip off the shovel or slide forward into the dug out hole when it is being used. Additionally, the thin upper edge can result in injury to the user when their foot is slipping off while attempting to push the shovel blade downward

Furthermore, there is a need for a high strength shovel blade configuration that enables such soil penetrating ability along with providing the user with a stable and secure area on the shovel blade for a stable foot placement allowing for greater forces to be exerted on the shovel blade by a user.

Thus, the need exists for solutions to the above problems with the prior art.

SUMMARY OF THE INVENTION

A primary objective of the present invention is to provide high strength shovels and trowels formed from metal and plastic for enhanced soil and sand penetration and cutting into roots.

A secondary objective of the present invention is to provide high strength shovels and trowels having a strengthened tip edge that does not bend and/or break when used.

A third objective of the present invention is to provide high strength shovels and trowels having a strengthened tip edge that disburses stress when used.

A fourth objective of the present invention is to provide high strength shovels and trowels with a high strength blade that can easily penetrate through grassy soil as well as small to moderate sized trees

A fifth objective of the present invention is to provide high strength shovels and trowels that have a stable and secure area on the blade for safe foot placement allowing for greater forces to be exerted on the blade by the user.

A high strength shovel, can include a longitudinal handle portion having an upper end and a lower end, a contiguous blade having an upper concave curved surface, and a lower surface, with a front end, and a rear end attached to the lower end of the handle, foot brakes extending upward from the rear end of the blade, the foot brakes allowing for a stable surface for the user during digging, narrow tip teeth edges extending outward from the front end of the blade, and contiguous embossment portions in the teeth edges for strengthening the blade during digging.

Each of the foot brakes can include a first bent flange extending substantially upward to the rear end of the blade, and a second bent flange extending rearward from the first bent flange.

The narrow tip teeth edges can include 8 narrow tip teeth edges. The narrow tip teeth edges can include 4 narrow tip teeth edges. The narrow tip teeth edges can include 3 narrow tip teeth edges. The narrow tip teeth edges can include 2 teeth edges, or one teeth edge. The narrow teeth edge can be generally triangular shaped or wedge shaped.

The embossment can have a tear drop shaped indented surface portion. The embossment can have a generally triangular shaped indented surface portion.

The generally triangular shaped indented portion of each narrow tip teeth edge can include a rounded tip and a rounded base.

Each of the narrow tip teeth edges can include a base on the front end of the blade, and each generally triangular shaped indented surface portion have bases extending rearwardly behind the base of the narrow tip teeth edges.

Each generally triangular shaped indented surface portion can include an enlarged width of approximately 0.63 inches, and a length between a base and a tip being approximately 1.25 inches, wherein the tip of the generally triangular shaped indented surface portion is spaced approximately 0.36 inches from an exterior tip of the narrow tip teeth edges. The blade can include a thickness of approximately 0.06 inches, and the indented surface portion has a depth of approximately 0.12 inches.

Each generally triangular shaped indented surface portion can include an enlarged width of approximately 0.71 inches, and a length between a base and a tip being approximately 1.31 inches, wherein the tip of the generally triangular shaped indented surface portion is spaced approximately 0.41 inches from an exterior tip of the narrow tip teeth edges. The blade can include a thickness of approximately 0.12 inches and the indented surface portion has a depth of approximately 0.22 inches.

Each generally triangular shaped indented surface portion can include an enlarged width of approximately 0.74 inches, and a length between a base and a tip being approximately 1.34 inches, wherein the tip of the generally triangular shaped indented surface portion is spaced approximately 0.35 inches from an exterior tip of the narrow tip teeth edges. The blade can include a thickness of approximately 0.13 inches and the indented surface portion has a depth of approximately 0.23 inches.

The first bent flange of the foot brakes can extend upward approximately 0.79 inches from the rear end of the blade, the second bent flange extends rearwardly approximately 0.49 inches from the blade, and the second bent flange is angled approximately 135 degrees to the first bent flange.

The foot brakes can include raised ribs for attaching the first bent flange to the rear end of the blade for reinforcing and strengthening the foot brakes.
