Description

BACKGROUND

This application claims priority to U.S. Provisional Application Ser. No. 61/759,104, filed Jan. 31, 2013, entitled “Snow Plow Cutting Edge.”
Snow plows can be mounted on a vehicle and used for removing snow, debris and ice from outdoor travel surfaces, such as roads, driveways, and walkways. A snow plow blade typically comprises contoured, and/or wedged plow surfaces, the bottom of which may rest upon the target surface during plowing, or a cutting edge attached to the bottom of the plow blade. Often, snow plow cutting edges are affixed to the bottom of the plow blade to provide a more desirable snow/ice removal edge, and/or provide a wearable surface that can be ready removed and replaced as needed, instead of replacing or repairing a damaged plow blade. Commonly, plow cutting edges are comprised of metal (e.g., steel), rubber, polyurethane or combinations thereof.

DETAILED DESCRIPTION

The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices can be shown in block diagram form in order to facilitate describing the claimed subject matter.
FIG. 1 is a component diagram illustrating a side perspective view of an embodiment of an exemplary cutting edge 100. The exemplary cutting edge 100 comprises a front surface 102 and a rear surface 104. In this embodiment, the front surface 102 is configured at a desired front angle to vertical, for example, where the desired front angle comprises an angle appropriate for snow and ice removal when engaged with a snow plow 150, such as between ninety and forty-five degrees from vertical (e.g., acute to the target surface).
In this embodiment of the exemplary cutting edge 100, the rear surface 104 comprises a first rear portion 108 and a second rear portion 110. The first rear portion 108 is configured to be at a desired rear angle, for example, where the desired rear angle of the second rear portion 110 comprises an angle that allows the rear surface 104 to be disposed adjacent to, and in contact with, a bottom portion 152 of the snow plow 150, when engaged with the snow plow 150. The second rear portion 110 defines a bottom extension 112. The bottom extension 112 comprises a rear top surface 114 configured to be relatively parallel to a target surface 158 (e.g., pavement) when the exemplary cutting edge 100 is engaged with the snow plow 150. The bottom extension 112 further comprises a rear face surface 116 configured to be relatively perpendicular to a target surface 158 (e.g., roadway) when the exemplary cutting edge 100 is engaged with the snow plow 150.
Further, in this embodiment of the exemplary cutting edge 100, the extension 112 extends rearward from the front surface 102 to a desired length, where the desired length, for example, allows the rear face surface 116 to be disposed at a position rearward of the bottom portion 152 of the snow plow 150, when the exemplary cutting edge 100 is engaged with the snow plow 150. As one example, the disposition of the rear face surface 116 on the extension 112 at the position rearward of the bottom portion 152 may allow the snow plow 150 to be effectively used for back dragging (e.g., pushing or moving snow and/or ice in a rearward direction with the plow).
This embodiment of the exemplary cutting edge 100 comprises a bottom surface 118 configured to be disposed relatively parallel to a target surface 158 when the exemplary cutting edge 100 is engaged with the snow plow 150. Further, the exemplary cutting edge 100 comprises a top surface 120. In the exemplary embodiment of FIG. 1, the top surface 120 comprises a plane orthogonal to a plane described by the bottom portion 152 of snow plow 150. However, in other embodiments, the top surface may comprise a plane disposed at a variety of angles, for example, parallel with the target surface 120, or other appropriate angles devised by those skilled in the art. Additionally, in this embodiment, a cut-out 124 is disposed at the corner where the front surface 102 and the top surface 120 meet. As an example, the cut-out 124 can comprise a concave arc with end points disposed at the top surface 120 and the front surface 102. However, it will be appreciated, that the cut-out 124 is not limited to this embodiment, and other cut-out designs are anticipated by those skilled in the art.
This embodiment of the exemplary cutting edge 100 comprises a fastener receiving hole 122, comprising a via disposed between the front surface 102 and the rear surface 104 (e.g., at the first rear portion 108). The fastener receiving hole 122 is configured to receive a fastener 154 (e.g., a bolt, rod, screw, etc.), for example, such that the fastener may be secured by a fastener securing component 156 (e.g., a nut, cotter pin, lock nut, etc.). In one embodiment, the exemplary cutting edge 100 may comprise a plurality of fastener receiving holes 122 disposed along the length of the front surface 102, configured to respectively receive one or more fasteners 154, for example, such that the respective fasteners 154 can be secured to the bottom portion 152 of the snow plow 150 to secure the exemplary cutting edge 100 to the snow plow 150.
FIG. 2 is a component diagram illustrating a profile view of an embodiment of an exemplary cutting edge 200. In this exemplary embodiment 200, a front surface 202, top surface 220, top cut-out 224, first rear portion 208 of a rear surface 204, and fastener receiving hole 222 may be disposed similarly as described above, in FIG. 1.
In this embodiment of the cutting edge 200, a bottom surface 216 comprises a first bottom portion 226 and a second bottom portion 228. The first bottom portion 226 and the second bottom portion 228 are separated by a bottom cut-out 216, which can comprise a triangular shaped cut-out; however, the bottom cut-out 216 may comprise an alternate polygon shape or other shapes known by those of skill in the art. The bottom cut-out 216 can define a first bottom extension 212 and a second bottom extension 214 of the exemplary cutting edge 200. As one example, the bottom cut-out 216 can provide relief for snow to compress when the snow plow 150 is lowered to the target surface 158, in preparation for back-dragging.
In one embodiment, a rear surface of the second rear bottom portion 210 may be disposed at a similar angle as a rear surface of the bottom cut-out 216. Further, a front surface of the bottom cut-out 216 may be disposed at a similar angle as the front surface 202. As one example, the second bottom extension 214 may facilitate moving of snow and/or ice from the target surface 158 when the snow plow 150 is moved in a forward direction (e.g., by an attached vehicle). Additionally, as an example, the first bottom extension 212 may facilitate moving of snow and/or ice from the target surface 158 when the snow plow 150 is moved in a rearward direction (e.g., back-dragging).

In the exemplary embodiment 300, a fastener 354, a fastener securing component 356 (e.g., comprising a washer component), a front surface 302, top surface 320, top cut-out 324, first rear portion 308 of a rear surface 304, and fastener receiving hole 322 may be disposed similarly as described above, in FIGS. 1 and 2.
In this embodiment of the cutting edge 300, a bottom surface may be disposed similarly as described above, in FIG. 1. In this embodiment of the cutting edge 300, a rear surface 304 comprises the first rear portion 308, a second rear portion 310, a bottom portion of the snow plow 352 and a third rear portion 326. The second rear portion 310 defines a bottom extension 312 with respect to a bottom surface 318. The bottom extension 312 comprises the surface of the second rear portion 310 disposed at an acute angle with respect to the bottom surface 318. As one example, the acute angle of the bottom extension 312 may comprise an angle that facilitates pushing of snow and/or ice when a vehicle attached to the snow plow 150 is directed in a rearward direction (e.g., back-dragging). Further, the third rear portion 326 may be disposed at an angle that is defined by plane that connects between the surface of the first rear portion 308 and the surface of the second rear portion 310.
FIG. 4 is a component diagram illustrating a profile view of an embodiment of an exemplary cutting edge 400. In this exemplary embodiment 400, a front surface 402 may be disposed similarly as described above, in FIGS. 1, 2, and 3. Further, a bottom surface 418 may be configured to be disposed relatively parallel to a target surface 158 when the exemplary cutting edge 400 is engaged with the snow plow 150. The exemplary cutting edge 400 comprises a rear surface 404, comprising a first rear portion 408, a second rear portion 410, and a third rear portion 426. The second rear portion 410 may be disposed at an angle that is similar to the front surface 402. A distance between the second rear portion 410 and the front surface 402 may define a width of the bottom surface 418. In one embodiment, the width of the bottom surface 418 may comprise a thickness of a bottom extension 414 that is determined by sound engineering judgment for pushing snow and/or ice by a snow plow.
The first rear portion 408 of the rear surface 404 can define a top rear extension 412 that may be configured to enclose the bottom portion of the snow plow 452. Further, the top rear extension 412 comprises a rear back surface 415 configured to be disposed relatively parallel to the front surface 402. Additionally, the top rear extension 412 comprises a rear face surface 416 configured to be relatively perpendicular to the rear back surface 415. The third rear portion 426 may be defined by a convex arc comprising ending points disposed at the rear face surface 416 and the surface of the second rear portion 410. As an example, a third rear portion 426 may be configured to provide a support between the first rear portion 408 and the second rear portion 410 when the exemplary cutting edge 400 is utilized for pushing snow and/or ice.
In one implementation, the front surface 402 may be configured to run from the target surface 158 and ending at a top surface 420, disposed adjacent to (e.g., and in contact with) the snow plow 150, for example, defining a top front extension 428 that encloses the front of the bottom portion of the snow plow 150. In one embodiment, the top rear extension 412 and the top front extension 428 can define a snow plow engagement cavity configured to receive the bottom portion 452 of the snow plow 150. Further, the exemplary cutting edge 400 can comprise a fastener receiving hole 422, comprising a cavity protruding, at least partially, from the front surface 402 through the top front extension 428, and into the top rear extension 412. The fastener receiving hole 422 is configured to receive a fastener 454 (e.g., a screw), for example, such that the fastener may secure the top front extension 428, and into the top rear extension 412 against the bottom portion 452 of the snow plow 150. As one example, the fastener may comprise a self-tapping fastener (e.g., bolt or screw) that can be driven into the fastener receiving hole 422 to secure the exemplary cutting edge 400 to the bottom portion 418 of the snow plow 152.
In one embodiment, the exemplary cutting edge 400 may comprise a plurality of fastener receiving holes 422 disposed along the length of the front surface 402, configured to respectively receive a fastener 454, for example, such that respective fasteners 454 can be secured to the bottom portion 418 of the snow plow 150 to secure the exemplary cutting edge 400 to the snow plow 150.
FIG. 5 is a component diagram illustrating a profile view of an embodiment of an exemplary cutting edge 500. In this exemplary embodiment 500, a front surface 516, top surface 520, and bottom surface 518 may be disposed similarly as described above, in FIG. 4. Further, the first rear portion 508 of the rear surface 504, and fastener receiving hole 522 may be disposed similarly as described above, in FIGS. 1, 2, and 3.
In this exemplary embodiment of the cutting edge 500, the front surface may comprise a first front portion 514, a second front portion 516, and a third front portion 528. The third front portion 528 may separate the first front portion 514 and the second front portion 516, and may comprise a notch 528 protruding partially into the front of the cutting edge 500. As one example, the notch may be defined by three edges, for example, comprising three sides of a square, or may comprise some other configuration selected using sound engineering judgment. In one implementation, the third front portion 528 (e.g., a notch) may be utilized as a wear indicator, for example, identifying how much of the bottom of the exemplary cutting edge 500 has been worn away (e.g., during use), thereby indicating when the cutting edge 500 may need to be replaced.
The rear surface 504 can comprise a first rear portion 508, a fastener 554, a fastener securing component 556 (e.g., comprising a washer component), a second rear portion 510, and a third rear portion 526 respectively defining a mid-rear extension 512. In this embodiment, the first and second rear portions 508, 510 may be disposed at a similar angle as the front surface 502. Further, the third rear portion 526 may be configured to receive the bottom portion 552 of the snow plow 150, such that the mid-rear extension 512, the third rear portion 526, and the first rear portion 508, at least partially, enclose the bottom portion 552 of the snow plow 150. In this way, for example, the mid-rear extension 512 may provide support to the cutting edge 500 during snow and/or ice removal operations.
FIG. 6 is a component diagram illustrating a profile view of an embodiment of an exemplary cutting edge 600. In this exemplary embodiment 600, a front surface 602 and bottom surface 618 may be disposed similarly as described above, in FIG. 5. A rear surface 604 of the exemplary cutting edge 600 can comprise a first rear portion 608, second rear portion 610, a third rear portion 626, a fourth rear portion 628, and a fifth rear portion 634.
The first rear portion 608 and the second rear portion 610 may be disposed at an angle similar to the front surface 602, and are offset by first bottom cut-out 636 defined by an arc-plane or flat plane that connects the first rear portion 608 and second rear portion 610, such that a distance between the first rear portion 608 and the front surface 602 is greater than a distance between the second rear portion and the front surface 602 (e.g., the width of the cutting edge 600 at the first rear portion 608 and the front surface 602 is thicker than the width of the cutting edge 600 at the second rear portion 610 and the front surface 602).
Further, the first rear portion 608, the second rear portion 610, and the third rear portion 626 respectively define a mid-rear extension 612. The fourth rear portion 628, fifth rear portion 634, and top surface 620 respectively define a top-rear extension 632. The third rear portion 626 may be disposed perpendicular to the front surface 602, and the fourth rear portion 628 and fifth rear portion 634 may be disposed relatively parallel to the front surface 602.
The third rear portion 626 and fourth rear portion 628 may be configured to receive a plow bottom attachment 630, selectively attached to the bottom portion of the snow plow 152, such that the mid-rear extension 612, the top-rear extension, the third rear portion 626, and the fourth rear portion 628, at least partially, enclose the plow bottom attachment 630.
In one embodiment, the plow bottom attachment 630 can comprise an ‘L’ shaped angle (e.g., comprising metal, steel, or an appropriate metal alloy). Further, the plow bottom attachment 630 may be selectively engaged with the bottom portion of the snow plow 152 using a fastener 154 (e.g., bolt) secured with a fastener securing component 156 (e.g., nut) through a series of fastener receiving holes 652 (e.g., vias) through the plow bottom attachment 630, a spacer 650 and the bottom portion of the snow plow 152. As one example, the spacer 650 may comprise a polymer and/or rubber based material.
Additionally, the fourth rear portion may comprise a fastener cut-out 634 configured to provide a space for a head of the fastener 154 to be disposed on the front of the plow bottom attachment 630. In one implementation, the configuration of the rear surface 604, comprising the first rear portion 608, second rear portion 610, a third rear portion 626, a fourth rear portion 628, and a fifth rear portion 634, may allow the exemplary cutting edge 600 to be selectively slide onto the plow bottom attachment 630, for example the engage the cutting edge 600 with the snow plow 150. That is, for example, instead of engaging the cutting edge 600 with the snow plow 150 using a fastener 154, the exemplary cutting edge 600 may be merely slide onto the bottom portion of the snow plow using the secured plow bottom attachment 630.
FIG. 7 is a component diagram illustrating a profile view of an embodiment of an exemplary cutting edge 700. In this exemplary embodiment 700, a front surface 702, top surface 720, a bottom portion 752 of the snow plow 150, bottom surface 718, top rear portion 708 of the rear surface 704, and mid-rear extension 712 of the rear surface may be disposed similarly as described above, in FIG. 5. Further, the fastener receiving hole 722 and fastening means 154, 156 may be disposed similarly as described above in one or more of FIGS. 1-5.
In this exemplary embodiment of a cutting edge 700, the rear surface comprises a second rear portion 710. The second rear portion 710 comprises a hinge receiving cut-out 724 configured to receive a cylindrical shaped hinge 732 engaged with a back-drag edge 730. The second rear portion 710 further comprises a first hinge stop extension 714, configured to provide a top mechanical stopping position for the back drag edge 730; and a second hinge stop extension 716 configured to provide a bottom mechanical stopping position for the back drag edge 730.
In one implementation, a cylindrical shaped hinge 734 engaged with a back-drag edge 730 may be slide into a hinge receiving cut-out 724, for example, where the hinge receiving cut-out 724 runs the length of exemplary cutting edge 700, from end to end, and the cylindrical shaped hinge 734 engaged with the back-drag edge 730 also runs the of exemplary cutting edge 700. Further, in one embodiment, the cylindrical shaped hinge 734 engaged with a back-drag edge 730 may comprise a polymer-based material, rubber-based material, and/or metallic material. Additionally the cylindrical shaped hinge 734 engaged with the back-drag edge 730 may be milled, cast, extruded, or otherwise formed (e.g., thermo-formed) or other techniques known by one of skill in the art.
As one example, when a vehicle engaged with the snowplow 150, thereby engaged with the exemplary cutting edge 700, is pushing snow in a forward direction, the back-drag edge 730 can rotate 750 backward, above and away from the target surface 158. Further, in this example, when the vehicle is pushing snow in a backward direction (e.g., back-dragging), the back-drag edge 730 can rotate 750 down to engage with the target surface 158, thereby providing a back-dragging edge for pushing snow backward.
FIG. 8 is an example embodiment 800 where one or more portions of cutting edges described herein may be implemented. In this embodiment, an exemplary cutting edge 802 is engaged with a snow plow 150. As one example, the cutting edge 802 may comprise a length that is similar to a width of the snow plow 150. That is, for example, the exemplary cutting edge 802 is configured to fit, and cover, an entire width of the snow plow 150. In one embodiment, the cutting edge 802 may comprise an appropriate polymer material, such as a polyurethane-based polymer. As one example, the polymer may be selected based on expected use and environmental conditions. As another example, the cutting edge 802 may comprise a rubber-based compound or other materials devised by those skilled in the art.
In one embodiment, the example cutting edge 800 can be attached to the snow plow 150 using a plurality of fasteners (e.g., 154, illustrated in previous figures) disposed along the length of the cutting edge 802. In one embodiment, the cutting edge 802 may comprise a fastener recess (not shown) disposed at the front of respective fastener receiving holes (e.g., 122, illustrated in previous figures). In this embodiment, the fastener recess may be configured to recess a head of a fastener below the front surface (e.g., 102, illustrated in previous figures) of the cutting edge 802.
