Abstract
Description
- This invention relates generally to plows for moving any plowable material, and more particularly to vehicle mountable plows for moving snow and having one or more plow blade wings to aid the plow blade in moving the snow.
- A wide variety of plows for mounting on pickup trucks, sport utility vehicles (“SUV's”), “skid steers,” and other vehicles for moving snow is in use. Among the plows in use are straight blade plows and center hinged blade V-plows.
- Another type of plow in use employs rotating, translating, or rotating and translating wings mounted on the ends of the plow blade. Translating wings are useful for configuring the blade of the plow in a longer extended length for plowing, and in a shorter retracted length for over road travel. Rotating wings are useful for configuring the blade of the plow into “bucket” and/or “pusher” configurations. In the bucket configuration, the wings are angled forwardly relative to the plow blade, typically at an angle of about 30°. In the pusher configuration, the wings are angled forwardly relative to the plow blade at an angle of about 90°. In either case, the forwardly angled wings prevent snow from sliding off the ends of the blade during plowing. Of course, if desired, one or the other of the wings could be forwardly angled relative to the plow blade, rather than both, depending on the snow conditions, obstacles encountered during plowing, etc.
- Examples of plows having wings which both rotate and translate are described in U.S. Pat. Nos. 6,442,877, 6,412,199, 6,408,549, 5,899,007, and 5,638,618, all assigned to Blizzard Corporation, Calumet, Michigan, and all hereby incorporated by reference herein. Each of these patents describes a plow having a slide mechanism and a hinge mechanism for adjustably mounting a wing to each end of the plow blade. Hydraulic cylinders are mounted to the snow plow blade for use in adjusting, i.e., rotating and translating, the plow wings.
- The plows of U.S. Pat. Nos. 6,442,877, 6,412,199, 6,408,549, 5,899,007, and 5,638,618 are not without criticism. The slide mechanisms can be subject to galling from snow, ice, salt, and corrosion, and thus can suffer from premature wear. More powerful, and hence heavier, hydraulic cylinders can be required to actuate the slide mechanisms if corroded, frozen, etc. due to increased sliding frictional forces. The dual hydraulic cylinders which impart translating and rotating motion to the wings can add to the cost, complexity, and weight of the plow. The hinge mechanism can also be subject to galling from snow, ice, salt, and corrosion, and thus it too can suffer from premature wear. More powerful, and hence heavier, hydraulic cylinders can be required to actuate the hinge mechanisms if corroded, frozen, etc. due to increased torsional resistance.
- It is desirable to improve upon current snow plows in use by providing a plow which is configurable to and between a longer extended length for plowing and a shorter retracted length for over road travel, and which is also configurable into bucket and/or pusher configurations, yet which does not suffer from the drawbacks of the plows of U.S. Pat. Nos. 6,442,877, 6,412,199, 6,408,549, 5,899,007, and 5,638,618.
- In one aspect, the hinge mechanism and its associated adjusting hydraulic cylinder of the plows of U.S. Pat. Nos. 6,442,877, 6,412,199, 6,408,549, 5,899,007, and 5,638,618 is eliminated and the wing is fixedly mounted at an angle. In this aspect, the invention is a plow assembly comprising a blade, structure attached to the blade and adapted to be attached to a vehicle for mounting the blade to and supporting the blade from the vehicle, and a wing attached to an end of the blade. The wing has a first portion mounted for movement along the blade to and between a retracted position and an extended position, and a second portion mounted in fixed relation relative to the first portion at an angle relative thereto.
- The first portion of the wing can be mounted for translational movement along the blade, for example, sliding movement along, for example, a forward side of the blade. The plow assembly can include an actuator for moving the first portion of the wing along the blade. The actuator can be a hydraulic cylinder. The second portion of the wing can be mountable in fixed relation relative to the first portion of the wing at at least two different angles relative thereto.
- In another aspect, the invention is a plow assembly comprising a blade, structure attached to the blade and adapted to be attached to a vehicle for mounting the blade to and supporting the blade from the vehicle, and a wing attached to an end of the blade. The wing is selectably mountable in fixed relation relative to the blade at at least two different angles relative thereto.
- The wing can be mountable in fixed relation relative to the blade at angles of about 0° and about 30°, of about 0° and about 90°, of about 30° and about 90°, and/or of about 0°, about 30°, and about 90°.
- In another aspect, the slide mechanism of the plows of U.S. Pat. Nos. 6,442,877, 6,412,199, 6,408,549, 5,899,007, and 5,638,618 is eliminated and the wing is mounted for rolling movement. In this aspect, a the invention is a plow assembly comprising a blade, structure attached to the blade and adapted to be attached to a vehicle for mounting the blade to and supporting the blade from the vehicle, and a wing attached to an end of the blade. The wing is mounted for rolling movement along the blade to and between a retracted position and an extended position. The wing can have a first and second portion, with the first portion mounted for rolling movement along the blade to and between a retracted position and an extended position, and the second portion mounted to the first portion at an angle relative thereto.
- The first portion of the wing can be mounted for rolling movement along a forward side of the blade. The plow assembly can include an actuator for moving the first portion of the wing along the blade. The actuator can be a hydraulic cylinder. The second portion of the wing can be mounted in fixed relation relative to the first portion of the wing. The second portion of said wing can be mountable in fixed relation relative to the first portion of the wing at at least two different angles relative thereto. The second portion of the wing can be mounted for rotating movement relative to the first portion of the wing. The plow assembly can include an actuator for moving the second portion of the wing relative to the first portion of the wing. The actuator can be a hydraulic cylinder.
- Blade assemblies for plow assemblies are also provided.
- The plow of the invention can thus be lighter, simpler, less expensive, and less prone to wear than plows having complicated rotating and translating wings wherein the wing rotates on a hinge mechanism, the wing translates on a slide mechanism, and two hydraulic cylinders are used to adjust the rotation and translation of the wing.
- These and other advantages of the present invention will become more readily apparent during the following detailed description taken in conjunction with the drawings herein, in which:
-
FIG. 1 is a rear perspective of a plow assembly according to the principles of the invention, -
FIG. 1A is an enlarged view of the left end of the blade assembly of the plow assembly ofFIG. 1 illustrating the blade wing in the retracted position, -
FIG. 1B is a view similar toFIG. 1A illustrating a first portion of the blade wing in the extended position and a second portion of the blade wing mounted in fixed relation relative to said first portion at an angle relative thereto. - FIGS. 2A-C are top views of the left end of the blade assembly of
FIGS. 1, 1A , and 1B illustrating the second portion of the blade wing mounted in fixed relation relative to the first portion at three different positions relative thereto, -
FIG. 3 is a rear view of the blade assembly of FIGS. 2A-C, -
FIG. 4 is a view similar toFIG. 1A but of an alternative embodiment of the invention, and -
FIG. 5 is a top view similar to FIGS. 2A-C but of yet another alternative embodiment of the invention. - Referring first to
FIG. 1 , there is illustrated aplow assembly 10 according to the principles of the invention. Theplow assembly 10 includes ablade assembly 20 and structure 30 (shown in phantom) attached to theblade assembly 20 and adapted to be attached to a vehicle (not shown) for mounting theblade assembly 20 to and supporting theblade assembly 20 from the vehicle. -
Blade assembly 20 includes a blade 40 which can have one or more stiffening ribs, forexample stiffening ribs lower torque tubes Ribs torque tubes wing 80 is attached to at least one end of the blade 40. For example, a pair of wings can be attached to the opposite ends of blade 40, such aswing 80 attached to left hand end of blade 40 andwing 82 attached to right hand end of blade 40. Since the constructions ofwings left hand wing 80 will be described in detail. - A
first portion 84 ofwing 80 is mounted for movement, for example, translational movement, sliding movement, etc., along the blade 40, for example along the forward side of the blade 40, to and between a retracted position (FIGS. 1 and 1 A) and an extended position (FIG. 1B ). A second portion 86 (shown in phantom inFIG. 1B ) ofwing 80 is mounted in fixed relation relative to thefirst portion 84 at an angle relative thereto.First portion 84 ofwing 80 can include one or more stiffening ribs, forexample stiffening ribs First portion 84 ofwing 80 can also have one or more stiffening torque tubes, for example, upper andlower torque tubes first portion 84.Ribs torque tubes first portion 84.Torque tubes torque tubes torque tubes - An actuator, for example a
hydraulic cylinder 100, can be included for moving thefirst portion 84 of thewing 80 along the blade 40. Thecylinder portion 102 ofhydraulic cylinder 100 can be mounted betweenribs rod portion 104 of thehydraulic cylinder 100 can be attached torib 90 offirst portion 84 ofwing 80.Hydraulic cylinder 100 can be, for example, a Lion 2500 PSI Heavy Duty Tie Rod Hydraulic Cylinder, with a 2 inch bore and 16 inch stroke, Model # 20TL16-112, available from Northern Tool and Equipment, Burnsville, Minn. - Referring now to FIGS. 1B, 2A-C, and 3,
second portion 86 ofwing 80 is illustrated.Second portion 86 is mounted in fixed relation relative to thefirst portion 84, albeit in three different positions. - As shown in
FIG. 2A ,second portion 86 is fixedly mounted tofirst portion 84 at about 0°. As an example,bolts 110 andnuts 112 can be used to secureflange 114 ofsecond portion 86 torib 90 offirst portion 84 via a first set of bolt holes inflange 114 andrib 90. Additional reinforcement ofsecond portion 86 tofirst portion 84 can be included. For example, upper and lower L-shapedbrackets 120 can each have aleg 124 and afoot 126.Foot 126 can be attached to rear side ofsecond portion 86.Leg 124 can have aplate 128 mounted thereto which extends laterally inwardly.Rib 90 can have aplate 130 mounted thereto which extends laterally outwardly belowplate 128. Each of the plates can have a plurality of holes spaced along their lengths. Apull pin 132 can be installed through aligned holes in theplates second portion 86 is fixedly mounted tofirst portion 84. - As shown in
FIG. 2B ,second portion 86 is angled forwardly relative tofirst portion 84 by about 30°, and is fixedly secured there bybolts 110 andnuts 112 passing through, for example, a second set of bolt holes inflange 114 andrib 90. Wedge shaped spacers 140 can be interposed betweenflange 114 andrib 90 for a secure bolted connection. - As shown in
FIG. 2C ,second portion 86 is angled forwardly relative tofirst portion 84 by about 90°, and is fixedly secured there bybolts 110 andnuts 112 passing through, for example, a third set of bolt holes inflange 114 andrib 90. Right angle or cube shapedspacers 142 can be interposed betweenflange 114 andrib 90 to make the bolted connection. - If desired,
wing 80 need not included a portion mounted for movement along the blade 40 to and between retracted and extended positions. In that case,wing 80 would includeonly portion 86 mounted in fixed relation relative to the blade 40, in multiple different positions. - Thus, no hinge mechanism is utilized to mount the
second portion 86 of thewing 80 tofirst portion 84 of thewing 80 in FIGS. 1A-C. Rather,second portion 86 is mountable tofirst portion 84 in fixed relation thereto in each of three different relative positions, 0°, 30°, and 90°. Eliminating the hinge eliminates its inherent reliability problems from the plow assembly. It also eliminates the need for a hydraulic cylinder to adjust the angle of the wing, thereby eliminating its reliability problems as well as reducing the cost of the plow assembly and reducing its weight. - Referring now to
FIG. 4 , and with like numbers representing like elements,first portion 84 ofwing 80 is mounted for rolling movement along blade 40. For example, blade 40 can include a series ofrollers 150 mounted onaxles 152 supported fromtabs 154 pressed out of blade 40.Second portion 86 ofwing 80 can be mounted to thefirst portion 84 at an angle relative thereto.Second portion 86 can be mounted in fixed relation tofirst portion 84 as discussed above in connection with FIGS. 2A-C. Alternatively,second portion 86 can be mounted for rotating movement relative to thefirst portion 84 of thewing 80 via, for example, ahinge 160 as shown inFIG. 5 . An actuator, for example a hydraulic cylinder, can be included for moving thesecond portion 86 of thewing 80 relative to thefirst portion 84 of thewing 80. - If desired, no
second portion 86 ofwing 80 need be included in the plow assembly. In that case,wing 80 would includeonly portion 84 mounted for rolling movement along blade 40 to and between retracted and extended positions. - Thus, no slide mechanism is utilized to mount the
first portion 84 of thewing 80 to the blade 40 inFIGS. 4 and 5 . Rather,first portion 84 is mounted for rolling movement along blade 40 to and between retracted positions and extended positions. Eliminating the slide mechanism eliminates its inherent reliability problems from the plow assembly. - While
hinge 160 for mountingsecond portion 86 ofwing 80 tofirst portion 84 ofwing 80 for relative rotating movement therebetween has been described as being used in conjunction withrollers 152 for mountingfirst portion 84 ofwing 80 for rolling movement relative to blade 40, hinge 160 could also be used in conjunction with the embodiment ofFIGS. 1, 1A , 1B, 2A-C, and 3, that is to say the embodiment withoutrollers 152. - The embodiments of the invention shown and described are merely for illustrative purposes only. The drawings and the description are not intended to limit in any way the scope of the invention as defined in the claims. Furthermore, those skilled in the art will readily recognize various changes to, and additional embodiments of, the invention, all of which will fall within the spirit and scope of the invention as defined in the claims. For example, while the invention has been shown and described in the context of straight blade plows, the invention can also be practiced with V-plows. And, while the invention has been shown and described in the context of plowing snow, the invention can also be practiced with other plowable materials. Further, while the invention has been shown and described in the context of being attached to the front of a vehicle and being pushed, the invention can also be practiced by being attached to the rear of the vehicle and being pulled. Yet further, while the invention has been shown and described as being attached to pickups, SUV's, and skid steers, the invention can be practiced by being attached to other vehicles. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
