Abstract
Description
- This application is a continuation application of U.S. Ser. No. 12/002,713, entitled GARDEN TOOL HEAD WITH COATED LEADING EDGE, filed Dec. 18, 2007.
- 1. Field of the Invention
- The disclosed concept relates to a garden tool head having a leading edge coated with a hardness enhancing material.
- 2. Background Information
- Garden tools for manipulating soil are well known in the art. Tools such as, but not limited to, shovels, scoops, spades, rakes, hoes, and scrapers typically include an elongated handle and a metal tool head. The tool head includes a socket structured to be coupled to the handle and a body. The body may be generally flat, e.g., a spade, generally arcuate, e.g., a shovel, or include a bent or angled portion, e.g. a hoe. Further, the body may include a plurality of prongs structured to be inserted into the soil, e.g., a rake. Whatever the shape of the body, there is typically a leading edge opposite the socket that is structured to be inserted into the soil. Thus, the leading edge of the tool head typically is subjected to more wear and tear than the medial portion of the tool head or the socket. That is, the leading edge is generally subjected to more friction and/or contact with debris, e.g. rocks, roots, etc., than the other portions of the tool head; however, because the tool head is made from metal, and is generally harder than the debris encountered, a tool head does not include any coatings or alternate materials structured to protect the tool head at the leading edge.
- The concept disclosed herein provides for a garden tool wherein the leading edge of the tool head has a leading edge coated with a hardness enhancing material. Preferably, the coating is selected from the group comprising: all performance or appearance enhancing coatings including but not limited to tungsten alloys, carbide alloys, titanium alloys, chromium alloys, steel alloys including stainless steels, brass alloys, copper alloys, bronze alloys and ceramics. The coating is preferably applied by a high velocity oxy-fuel process or an electric arc spray. Using such application methods the body of the tool head may be masked to provide a clean line of demarcation between the coated portion and the non-coated portion. The coated portion is, typically, a different color than the metal tool head. Further, the coating material may have a dye, or other coloring agent incorporated therein, to enhance the visual appearance of the coated portion. Further, while the coating is, preferably, generally smooth, the coating process and/or material may include particulate matter that results in a gritty or specked appearance.
- The coating may be applied by other means such as, but not limited to, dipping in a reservoir of liquid, plasma spray coating, plasma transferred arc, gas detonation coating, cold gas coating, plating or deposition methods. Such an application method typically results in a generally straight, laterally extending border between the coated portion and non-coated portion of the tool head. However, masking may still be used on the tool head to define the shape of the coated portion. Further, depending upon the nature of the hardness enhancing material, masking may be used to conserve the hardness enhancing material. For example, if the hardness enhancing material is initially in a water based solution, a hydrophobic masking material may be used to repel the hardness enhancing material from the masked material and return the liquid to the reservoir as the tool head is lifted from the reservoir.
- A full understanding of the invention can be gained from the following description of the preferred embodiments when read in conjunction with the accompanying drawings in which:
-
FIG. 1 is an isometric view of a garden tool with a coated tool head. -
FIG. 2 is a front view of a garden tool with a coated tool head. -
FIG. 3 is a back view of a garden tool with a coated tool head. -
FIG. 4 is a first side view of a garden tool with a coated tool head. -
FIG. 5 is a second side view of a garden tool with a coated tool head. -
FIG. 6 is a top side view of a garden tool with a coated tool head. -
FIG. 7 is a bottom side view of a garden tool with a coated tool head. - As shown in
FIG. 1-7 , agarden tool 10 includes anelongated handle 12 and atool head 14. It is noted that the size of thehandle 12 is adaptable to the purpose of thetool head 14. That is, as shown, thegarden tool 10 is a full sized shovel wherein thehandle 12 is about five feet long. It is understood that if the tool were a hand shovel (not shown), thehandle 12 would be much shorter, typically about 6 inches long. As shown, thetool head 14 is a shovel, however, it is understood that thetool head 14 may be any type such as, but not limited to, scoops, spades, rakes, hoes, and scrapers. Thetool head 14 has abody 15 with afront side 16, and back side 17 (FIG. 3 ), a leadingedge 18,side edges medial portion 20, and arear edge 22. Each of theedges face 19, 23, 31(FIG. 6 ), 33 (FIG. 4 ) respectively, that extends between thefront side 16 and theback side 17. Typically, the tool headrear edge 22 includes asocket 24 structured to be coupled to thehandle 12. Thetool head 14 is structured to engage a substrate such as, but not limited to, dirt, soil, sand, gravel, loam, silt, earth or any combination thereof. The toolhead leading edge 18 is structured to initially penetrate the substrate prior to the bodymedial portion 20 entering the substrate. In the embodiment shown inFIGS. 1 and 2 , thetool head 14 is ashovel head 26 wherein the toolhead leading edge 18 approximates the shape of a parabola having a generally forwardly extendingcurved edge 28 at the middle of thebody 15 and which extends to the two generally parallel,opposing side edges - The
tool head 14 includes acoating 40 of a hardness enhancing material. Thecoating 40 may be selected from the group comprising: tungsten carbides, chromium carbides, titanium, aluminum bronze or any of the afore mentioned materials. Thecoating 40 is preferably applied to thetool head 14 as a spray by such methods as a high velocity oxy-fuel process or an electric arc spray. Thecoating 40 is disposed on the toolhead leading edge 18 in a pattern having a leadingedge 42 and arear edge 44, thereby defining a coatedportion 46 of thebody 15 and anuncoated portion 48 of thebody 15. Typically, thecoating leading edge 42 corresponds to the toolhead leading edge 18. Thecoating 40 also typically covers the leadingedge face 19. - By controlling the shape of the spray stream, the pattern of the applied
coating 40 may be selected from any pattern; however, in a preferred embodiment, thetool head 14 is covered with amasking material 36, such as but not limited to,masking tape 38 during the application of thecoating 40. By utilizing a masking material 36 (shown in ghost), the pattern of thecoating 40 on thetool head 14 may be controlled. For example, as shown inFIGS. 1-7 , thecoating 40 on the toolhead front side 16 is disposed in a pattern wherein the coatingrear edge 44 is spaced about one inch from the toolhead leading edge 18 and generally corresponds to the shape of the toolhead leading edge 18 over the length of thecurved edge 28 and tapers to meet the two generally parallel,opposing side edges FIG. 3 , the pattern of thecoating 40 on the tool head backside 17 may be generally the same as the pattern of thecoating 40 on the tool head front side 16 (FIG. 2 ). - However, it is understood that the pattern of the
coating 40 on the tool head backside 17 may be different than the pattern of thecoating 40 on the toolhead front side 16. For example, the shape of the coatingrear edge 44 may correspond to the shape of the toolhead leading edge 18 over both thecurved edge 28 as well as the two generally parallel,opposing side edges FIGS. 8-15 . Thus, for example, thegarden tool 10 may have thecoating 40 applied on the toolhead front side 16 as shown inFIG. 2 and applied to the toolhead back side 17 as shown inFIG. 10 . Any of the patterns of thecoating 40 described herein may be applied to either the toolhead front side 16 and/or the tool head backside 17. - The
coating 40 may also be applied to thetool head 14 by dipping thetool head 14 into a reservoir containing the hardness enhancing material. Thus, provided thetool head 14 was maintained in a generally vertical orientation while being dipped, thecoating 40 would be disposed in a pattern wherein the coatingrear edge 44 extends generally laterally across the toolhead front side 16, as shown inFIGS. 16-21 ; however, thetool head 14 may also be covered with a maskingmaterial 36 while thetool head 14 is being dipped, thereby allowing control over the resultingcoating 40 pattern. - Further, depending upon the nature of the hardness enhancing material, the masking
material 36 may be used to conserve the hardness enhancing material. For example, if the hardness enhancing material is in a water-based solution, ahydrophobic masking material 36 may be used to repel the hardness enhancing material from the maskingmaterial 36 and return the solution to the reservoir as thetool head 14 is lifted from the reservoir. - As shown in
FIGS. 22-28 , thetool head 14 may include other structural elements such as, but not limited to, acorrugated portion 50 disposed adjacent to the leadingedge 18. As shown, thecorrugated portion 50 is disposed in a pattern wherein thecorrugated portion 50 extends about one inch from the toolhead leading edge 18 and generally corresponds to the shape of the toolhead leading edge 18 over the length of thecurved edge 28 and tapers to meet the two generally parallel, opposing side edges 30, 32. In such a configuration, thecoating 40 is preferably applied over thecorrugated portion 50. Further, as shown inFIG. 24 , thecoating 40 may include a particulate matter resulting in acoating 40 with a gritty or specked appearance. - As shown in
FIG. 29 , thetool head 114 is a rake. Therake tool head 114 includes a base 115 having a plurality oftines 115A extending generally perpendicular thereto. As before, thebase 115 and the plurality oftines 115A have aforward side 116, and back side (not shown), and eachtine 115A has aleading edge 118, side edges 130, 132, amedial portion 120, and arear edge 122. In this embodiment, thecoating 40 is typically applied to all sides of the distal end of thetines 115A; however, as noted above, a maskingmaterial 36 may be applied to those portions of thetool head 114 that should remain free from thecoating 40, or a well controlled spray may be used to limit the application of thecoating 40 to selected areas of thetool head 114. - While specific embodiments of the invention have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of invention which is to be given the full breadth of the claims appended and any and all equivalents thereof.
