Abstract
A snow plow apparatus comprises a snow plow main blade, end blade sections telescopingly mounted to ends of the main blade for sliding extension and retraction, and mechanical fasteners fixing a selected telescoped position of the end blade sections on the main blade. The main blade has a vertical cross section with linear portions connected by a formed channel-shaped center portion that gives the blade greater bending strength, and includes flanged upper and lower edges. The end blade sections match the main blade's vertical cross section, and include top and bottom flanges that slidably engage the upper and lower edges. Mechanical fasteners engage aligned holes in the flanges to fix a selected extended position of the blade end sections. End plates attached to the blade end sections retain snow on the face of the main blade during use.
Description
- This application claims benefit under 35 USC section 119C= of provisional application Ser. No. 61/863,617, filed Aug. 8, 2013, entitled ADJUSTABLE-WIDTH SNOW PLOW, the entire contents of which are incorporated herein in their entirety.
- The present invention relates to snow plows for trucks and utility vehicles, and more particularly relates to a back-of-vehicle snow plow apparatus (called a “back plow” herein) with adjustable end sections that can be adjusted to a desired width setting, such that a single snow plow apparatus can satisfy different snow plow width requirements.
- The end-to-end length dimension of snow plows is important to snow plowing companies and professionals (called “snow plowers” herein) for several reasons, such as needs related to vehicle capabilities, and/or to highway transport requirements, to the snow plow work itself (e.g. a desire for greater width passes at job site(s) or a need for shorter width passes due to width limitations from obstructions), the snow plower's preferences, and other reasons. A more subtle issue for snow plow manufacturers and distributers concerns inventories. Specifically, there are so many different blade lengths desired that the manufacturers and distributers have difficulty keeping sufficient inventories of all the different snow plows in stock that are exactly the right size for each different potential customer. This is especially problematic when inventories of snow plows are low and when a customer urgently needs a plow with very short lead time.
- It would be desirable to provide a single back plow capable of satisfying different length dimension requirements, where the length dimension is not known ahead of time, or at least is decided with a very short lead time. Still further, a back plow capable of use on different width vehicles would provide additional flexibility for large plowing operations, where different sized plow widths are needed.
- In one aspect of the present invention, a snow plow apparatus comprises a snow plow main blade, end blade sections telescopingly mounted to ends of the main blade for sliding extension and retraction, and mechanical fasteners for fixing a selected telescoped position of the end blade sections on the main blade.
- In another aspect of the present invention, a method of providing a single snow plow apparatus capable of providing a desired adjusted length, comprises providing a snow plow main blade, telescopingly mounting end blade sections on ends of the main blade for sliding extension and retraction, and moving the end blade sections to a desired telescoped position, and mechanically fastening the end blade sections on the main blade to fix the selected telescoped position of the end blade sections on the main blade, thus providing a selected total dimensional length.
- In another aspect of the present invention, a snow plow apparatus includes a snow plow main blade defining a length, end blade sections adjustably attached to the main blade for movement to at least three different-blade-width adjusted positions with the end blade sections lying parallel the length in all the positions, and a mechanical fastening system including fasteners to fix a selected one of the at least three positions, whereby the end blade sections can be fixed on the main blade in one of the positions in order to provide a selected total dimensional length.
- These and other aspects, objects, and features of the present invention will be understood and appreciated by those skilled in the art upon studying the following specification, claims, and appended drawings.

FIGS. 22-23 are perspective and end views of the right end plate slide ofFIG. 19 . -
FIG. 24 is a perspective view of a right hat channel assembly ofFIG. 19 . -
FIGS. 25-26 are photographs of top views of the back plow ofFIG. 1 ,FIG. 25 showing the right wing in a middle-extended position,FIG. 26 showing the wing in a fully-retracted position, and bothFIGS. 25-26 showing a third hole for holding the right wing in a fully-extended position. - The present back blade apparatus 30 (i.e. a “back plow”) (
FIG. 1 ) comprises a snow plow main blade assembly 31 (i.e. “main blade”) and right and leftend blade assemblies 32 telescopingly mounted to ends of themain blade assembly 31 for sliding extension and retraction. The telescoping mounting arrangement is referred to herein as “adjustability”, since (in the illustrated apparatus 30) it allows theend blade assemblies 32 to be moved to three different extended positions, with mechanical fasteners fixing a selected telescoped position. The adjustability of selecting an extended position allows a seller ofapparatus 30 to inventory asingle apparatus 30, yet with thatsingle apparatus 30 still satisfy different width requirements of different customers. - The illustrated main blade assembly 31 (
FIG. 1 ) includes aboard back blade 33 withbrackets 34 forming part of a receivedmount assembly 35 for picking up theblade apparatus 30. The board back blade 33 (FIG. 6 ) has a vertical cross section defined by a top edgestiffening flange 36 with upperreverse lip 37, topvertical section 38,channel 39 with angled side walls, bottomvertical section 40, and a bottomedge stiffening flange 41 with lowerreverse lip 42. Aspacer 43 is attached to the bottom outer edge of theboard back blade 33, and there are a series oflower holes 44 for attachment of a wear plate 45 (also called “wear edge” herein). One of the threeholes 46 are aligned with a mating hole on theend blade assembly 32 to receive a bolt to fix an extended position of theend blade assemblies 32 on themain blade assembly 31 at a bottom region. Theholes 46 also secure an end of thewear plate 45. Thetop holes 47 in the mainboard back blade 33 attach a top of theend blade assembly 31 to theback blade assembly 31. - The non-linear shape of the board back plate including the
channel 39 and top and bottomedge stiffening flanges 36 adds considerable strength to theapparatus 30, such that a thinner gage material can be used to form theboard back blade 33. For example, a 0.18 inch thick steel sheet can be used instead of a 0.25 inch thick sheet (which would typically be used on a flat board plate), which change significantly reduces the total weight ofassembly 30, while still maintaining structural integrity and strength of theapparatus 30. - The end blade assemblies 32 (
FIG. 8 ) each include an end plate slide 48 (also called an “end plate” herein) that generally match a vertical cross section of themain board blade 33, and further include a wing plate 49 (also called an “end plate” herein). Theend plate slide 48 has a vertical cross section defined by a top edgestiffening flange 51 withreverse lip 52, topvertical section 53,channel 54 with angled side walls, bottomvertical section 55 including a forwardly offsetlower portion 56 defining an outboard-open slot 57, and a bottomedge stiffening flange 58 withreverse lip 59. The shape of theend plate 49 allows theend blade assembly 32 to telescopingly slide onto an end of theboard back blade 33, with theslot 57 receiving thewear plate 45 on themain board blade 33. The top and bottomedge stiffening flanges bottom flanges end blade assemblies 32 on each end of themain board blade 33. - The
channels 39/54 andtop flanges 36/51 andbottom flanges 41/58 provide a guide/track that facilitates the extension of theend plate assemblies 32 on themain plate assembly 31. Thelower holes 60 attach awear plate 61 to theend plate slide 48, and at least onehole 60 also provides attachment of a bottom of theend plate slide 48 to themain back blade 33 in one of the selected extended positions.Top holes 62 in theend plate slide 48 also provide attachment of a top of theend plate slide 48 to themain back blade 33 in one of the selected extended positions. Awear plate 63 is attached to a bottom of thewing plate 49. It is noted that unused holes, including holes for fixing theend blade assemblies 32 onto themain blade assembly 31, are covered when theend blade assemblies 32 are adjusted to different positions and when wear plates are attached, which advantageously covers the unused holes and prevents “bleed through” or pass through of plowed snow during use. It is also contemplated that a plug (rubber grommet, fastener, or other material) can be used to plug unused holes. - Notably, the structure providing the present adjustability provides a robust and durable connection of the end plate assemblies 32 to the main
back plate assembly 31, such that overall functional strength and integrity is not comprised. At the same time, the adjustability allows asingle apparatus 30 to be adjusted to multiple positions (three such adjusted positions being illustrated), thus greatly assisting sellers of thepresent apparatus 30, since multiple customers can be satisfied by asingle apparatus 30. The illustratedapparatus 30 is about 13″ to 22″ height, and can be adjusted to 84 inch, 90 inch or 96 inch widths. However, it is contemplated that alternative sizes are within a scope of the present invention. -
FIGS. 1-4 are perspective, top, front, and cross-sectional side views of theback plow apparatus 30 with mechanically-lockable adjustable wings (end blade assemblies 32) attached to amain blade assembly 31.FIG. 5 illustrates an enlarged side view of theapparatus 30 with back blade assembly 31 (includingback blade 33 and main wear edge 45) and wing blade assemblies 32 (including awing plate 33 and wear edge 61)FIGS. 6-7 are perspective and front views of the mold board back plate inFIGS. 1-5 .FIGS. 8-10 are perspective, side and front views of the end plate assembly inFIGS. 1-5 .FIG. 11 is a perspective view of the end plate ofFIG. 8 . -
FIGS. 12-15 illustrate a modified version of an apparatus with adjustable wings embodying the present invention. InFIGS. 12-15 , similar and identical components, characteristics, and functions are identified using the same number but with a letter “A”. This is done to reduce redundant discussion. - The modified
back plow apparatus 30A (FIGS. 12-15 ) includes amain back blade 31A with mechanically-locked adjustable wings (end plate assemblies 32A). Theapparatus 30A includesitems 33A-46A, 48A-63A. However, components are modified for increased strength. For example, acorner brace 65A is extended at 45 degrees between theend plate slide 48A and theend plate 49A. Also, thebrackets 34 are made heavier duty for increased loading and stress. Also, the main board backblade 33A is modified so that the upper and loweredge stiffening flanges Vertical tube segments 66A (three shown) are welded between thetube flanges blade 33A). Notably themain blade sections 38A-40A are co-planar. - The top
edge stiffening flange 51A is formed as an integral part of the end plate slide 48A (FIG. 22 ), but the bottom edge stiffening flange is formed by a hat shapedchannel 58A/59A formed as a separate part (FIG. 24 ). Thechannel stiffening flange 58A is bolted to a bottom of theend plate slide 48A as part of a sandwich abutted assembly when assembling theend blade assemblies 32A to themain blade assembly 31A (FIG. 15 ).FIG. 25 shows a mid-extended assembled position,FIG. 26 shows a fully retracted assembled position, and not shown but defined by the third hole inFIG. 25 is the fully extended position. Theillustrated apparatus 30A is about 13 inch to 22 inch high, about 24 inch deep, and adjustable to 90 inch, 96 inch, and 102 inch widths. Again, alternative sizes and shapes are contemplated to be within a scope of the present invention. - It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
