Abstract
An assembly for providing the secure mount of warning lights on the top and/or back side of the blade of a snow plow or road grader. The assembly is designed to protect the assembly from a harsh environment and help a mounted light withstand the shocks and impacts regularly experienced by a plow when in use.
Description
- This application claims priority to provisional patent application Ser. No. 60/727,589, filed Oct. 17, 2005.
- 1. Background of the Invention
- This invention relates generally to an apparatus for mounting electrical features on a plow assembly, and more particularly to a structure for effectively mounting electrical warning lights on a plow blade such that the lights and components are adequately protected.
- 2. Discussion of the Prior Art
- Snow removal is an important task in colder climates where it is necessary to ensure that the public has safe access to roads and areas affected by storms and inclement weather. Also important is the ability to safely conduct road work, landscaping, and related jobs in warmer areas. A variety of work vehicles mounted with snow plows or road graders are typically used to accomplish these tasks. However, when road graders and snow plows are used to clear snow and other material or to groom gravel roads, their presence can potentially pose a safety risk to others on the road.
- One common safety problem is that when these vehicles are operated to plow snow or the like, the left end of the plow blade often will extend laterally beyond the vehicle's body. This configuration, combined with conditions often providing limited visibility, poses a risk that other on-coming vehicles or those passing on the left of the road grader/plow may hit the blade.
- One way in which to address this problem, that has been suggested in the past, is by mounting lights on or around the plow to help improve visibility during night operation as well as to provide additional warning illumination. Examples of these configurations include light bar arrangements on the upper edges and ends of the plow and configurations which fix a plurality of lamps to the top portion of a snow plow. While these devices might provide some enhanced visibility of plows, they are not well designed to provide adequate warning lights while protecting and securing the lighting assembly in an effective manner.
- The harsh conditions and frequent and sustained impacts on a plow blade require that a much more sturdy and reinforced design be made than the previously contemplated devices. A plow having mounted lights must overcome the problem of relatively fragile lights and electrical connections being subjected to undesirable weather conditions and destructive shaking and jolting of a plow blade.
- The light mounting assembly for plow blades and grader blades in accordance with a preferred embodiment of the present invention includes an elongated housing member extending parallel with and fixed to the top of the plow or grader blade, a pair of mounting brackets joined to the ends of the plow blade, electrical light members attached to the mounting brackets at the ends of the plow blade, and steel pipe connecting the housing member to the electrical light members.
- Alternatively, the assembly may include outer frames joined to the sides of the back of a plow, a strobe light surrounded by each frame, and a plurality of flexible dampening members supporting the strobe light within the outer frames.
- The foregoing features, objects and advantages of the invention will become apparent to those skilled in the art from the following detailed description of a preferred embodiment, especially when considered in conjunction with the accompanying drawings in which like numerals in the several views refer to corresponding parts.
-
FIG. 1 is a front view of the mounting assembly of the present invention; -
FIG. 2 is a left side perspective view of a portion of the mounting assembly of the present invention; -
FIG. 3 is a left side perspective view of the mounting assembly of the present invention showing the light assembly and protective shield for associated electrical wiring; -
FIG. 4 is a front perspective view of the lamp assembly mounted in accordance with the present invention; and -
FIG. 5 is a perspective view of the mounting assembly of an alternative embodiment of the present invention. - Referring to
FIG. 1 , thelight mounting assembly 10 of the present invention is seen in schematic form. It is generally made up of acentral housing tube 12,conduit tubes 14,mounting brackets 16, andlight boxes 18. - These components generally make up an assembly where flashing lights are mounted on the upper corners of a plow/ road grader blade 20 (
FIG. 2 ).Light boxes 18, comprising forward and rearward directed LED strobe lights, are bolted to amounting bracket 16 which bolts to theplow blade 20 proximate its opposed ends, preferably using the same bolt holes that are normally used for attaching the blade'swear plates 22. SeeFIG. 3 . Thewiring 24 for the lights comes from the road grader's lighting system. To protect this insulatedwire 24 leading to thelamp assembly 18, it is encased in steel conduit orpipe 14 and a larger diameter steeltubular housing member 12. The insulatedwire 24 then proceeds into thelight boxes 18 welded tobrackets 16. Thesebrackets 16 are then bolted to the upper edge of the plow or road grader'sblade 20. The invention is well-suited for use on straight plow blades as well as on wing blades. - The schematic drawing of
FIG. 1 demonstrates how wiring 24 from the plow/grader's lighting system is supplied to the center of thecentral housing tube 12 through a grommet located in a drilledopening 26 and eventually leads tolight boxes 18, viaconduit pipes 14. Once inside thehousing tube 12 thewiring 24 extends in opposite axial directions away fromcentral housing tube 12 by passing from both ends of thehousing 12 intosteel pipes 14.Theses pipes 14 are adapted to be attached to an upper edge of the plow blade and extend toward each respective side of theplow blade 20. They eventually join to junction boxes on which lamp assembles 18 are mounted by means ofbrackets 16 that are affixed to the opposed ends of theplow blade 20. In this way, the electrical power supply is effectively protected from damage and moisture as its path spans the distance between the plow/road grader's lighting system andlight assemblies 18. - Without limitation,
housing member 12 may comprise a four inch diameter steel pipe havingend caps 30. Theend caps 30 are provided with bores and extending a predetermined distance through the bores are one-half inchdiameter steel pipes 14. The assembly ofFIG. 1 is adaptable for attachment to truck mounted plows, tractor mounted plows and road graders. -
FIG. 2 discloses a partial side view of the assembly in place on a plow blade.Central housing tube 12 can be seen located just above theplow blade 20. Thishousing tube 12 generally runs axially parallel to the length dimension of theplow blade 20. A flatbar mounting bracket 28 joins thehousing tube 12 to the top edge portion of the back face of theplow blade 20. The flatbar mounting bracket 28 is preferably welded to the outer surface ofhousing tube 12 on one end and is bolted to theplow blade 20 on the opposite end.Housing tube 12 is shown to have a tubular, cylindrical shape withend caps 30 and a drilledopening 26 in the side of the cylinder through which wiring 24 passes. Theend caps 30 of thehousing tube 12 each have a smallcircular opening 32 through which conduit 14 exits on either side of thehousing 12 Thesecircular openings 32 may include a double lippedgrommet seal 34 to ensure that thewiring 24 within thehousing tube 12 is not subjected to dirt and moisture. -
FIG. 3 shows another perspective side view of theassembly 10. From this view the light assemblies 18 and a side of the plow blade is more fully illustrated. The pipe orconduit 14 extends generally parallel to the top of theplow blade 20 as it leaves thehousing tube 12 and is secured by abracket 36 for support. Shortly beyond thebracket 36, thepipe 14 makes, roughly, a 90° bend such that it extends upward to thelight assembly 18.Light assembly 18 in one embodiment is made up of two box shaped housings comprising forward and rearward LED strobe lights. These commercially-available components allow for light to be directed to both the front and the rear of theplow blade 20. Such LED strobe lights come in various colors including amber as authorized by the U.S. Dept. of Transportation and are commercially available from NOVA Electronics, Inc. of Colchester, Conn. - Supporting these
light assemblies 18 are mountingbrackets 16. Themounting brackets 16 have a curvedlower portion 38 which conforms to the shape of the back of theplow blade 20 and a flatupper portion 40 which projects vertically upward from the top edge of theplow blade 20 when it is attached. Thelower portion 38 of thebracket 16 additionally containsholes 42 which match the same bolt holes in the blade that are normally used for bolting on the blade'sreplaceable wear plates 22. The mountingbracket 16 is accordingly fixed in place bybolts 44 extending through the existing holes in the plow's face. -
FIG. 4 illustrates a front, partial perspective view of theplow assembly 10.Blade wear plates 22 cover the top front comers of the front face of the plow. Theseplates 22 typically are used to direct snow away from the plow and are replaceable as wear makes it necessary. As previously mentioned, theseplates 22 also provide the holes through whichbolts 42 extend within theplow face 20 to hold mountingbrackets 16 and thestrobe lights 18 to the plow assembly. Thetubular housing 12 and theconduit 14 afford a solid, dry, protective shield for the electrical wiring preventing breakage and/or wearing thereof, even in the most severe working environments. -
FIG. 5 shows an alternative embodiment of the present invention in which a unique light assembly is attached to the rear face of theplow blade 20. The assembly generally comprises a commercially availablecentral strobe light 46 contained within a moisture-proof strobelight housing 48. The assembly is shown centrally located near the end edge of the back of theplow blade 20. - A
rectangular frame 50 of the assembly is clamped, bolted, welded or otherwise attached to either the side lip or back of theplow 20. Theframe 50 comprises four metal side members, as at 56, which are welded or otherwise fastened together in a generally square shape. - Referring still to
FIG. 5 , centrally located withinframe 50 is thestrobe light 46 and strobelight housing 48. Strobelight housing 48 is generally a hollow cylindrically shaped cam member which terminates in aflat flange 62 around theround opening 64. Thisflat flange 62 contains four equally spacedattachment hole locations 66 around thestrobe housing 48 perimeter. Theattachment hole locations 66 provide a structure which allows resilient straps as at 52 to stretch between theattachment locations 60 of theframe 50 and theattachment locations 66 around theflange 62 of thestrobe housing 48. In this way, eightresilient straps 52 can be placed in tension to provide vibration isolated support for thestrobe housing 48 and are configured such that thestrobe housing 48 will experience a dampening of vibrations when theplow blade 20 is jolted and impacted during use. - Located within the
strobe housing 48 is an array of LED strobe lights 46. These strobe lights inarray 46 are protected around the perimeter by a seal member (not shown) placed in between thestrobe light array 46 andstrobe housing 48. When in use, thelight array 46 will face outward from the rear face of theplow 20. Placing a flashing strobe light array in this location enables drivers approaching from the rear to better see the location of the plow blade, and will reduce the danger to other motorists. Also within thestrobe housing 48 is wiring which will exit thestrobe housing 48 via anelectrical cord 54 either through anopening 74 in the side of the strobe housing 46 (seeFIG. 5 ) or from the rear opening (not shown) in the back side of thestrobe housing 46. Thewiring 54 can be shrouded byconduit 14 as it exits the strobe housing - While this embodiment of the present invention has been primarily described as having a configuration utilizing a frame equipped with eight resilient straps, a more simplified version utilizing less than eight straps and corresponding components is also well within the scope of this invention. Also, the light assembly can be affixed to a top edge of a plow blade so as to e viewable to on-coming motorists.
- This invention has been described herein in considerable detail in order to comply with the patent statutes and to provide those skilled in the art with the information needed to apply the novel principles and to construct and use such specialized components as are required. However, it is to be understood that the invention can be carried out by specifically different equipment and devices, and that various modifications, both as to the equipment and operating procedures, can be accomplished without departing from the scope of the invention itself.
