Description
Background of the Invention
It is common practice in snow belt areas to attach snow plows to the front of pick-up and other small trucks during the snow season, and to then remove the plows in the spring when the snow season is over. Generally, the attachment for the plow consists of a plow support bolted to the understructure of the truck. The plow support extends forwardly from the truck and terminates in a pair of spaced support projections located under and forward of the truck bumper. The height controlling mechanism for supporting the plow and for varying its height above the roadway is bolted to the support projections. The steering mechanisms for steering the plow are forward extending pivot support and hydraulically operated pistons which are also supported from the understructure of the vehicle.
When the plow is removed from the truck, the steering and height control mechanisms are removed without difficulty. To remove the plow support is an extensive job, as is its reinstallation in the fall. Most truck operators opt to leave the support on the vehicle, and this results in unsightly protrusion of the support projections from the front of the truck. These projections create a hazard to people and to other vehicles because they are positioned in front of and below the truck's bumper. Furthermore, it is exposed to the weather, and will rust.
Summary of the Invention
This invention overcomes the foregoing problems, and provides a snow plow support cap which not only enhances the appearance of the truck, but also provides protection against the hazzard of the support projections. In addition, the cap provides a useful platform or step enabling better service access to the truck's engine. The support cap is configured to be bolted to the support projections through the same holes used to bolt the plow elevation mechanism, and to permit the uninhibited operation of the plow steering mechanism.
The Drawings
For a clearer understanding of the nature of the advantages of the invention, reference should now be made to the following specification and to the accompanying drawings in which:
FIG. 1 is a view showing the plow support and the cap assembled, and
FIG. 2 is a view, partially in phantom, showing the plow support and the cap disassembled.
Detailed Description of the Drawings
Referring to the drawings, I show a conventional plow support 10 which is mounted to the understructure of a modern pick-up truck (not shown). As best seen in FIG. 2, the support consists of a pair of structural support arms 12 and 14. While the arms 12 and 14 are shown broken away, it will be understood that these arms extend under the truck and are appropriately bolted to the understructure of the truck. The arms 12 and 14 terminate in angle iron projections 16 and 18. The projection 16 and 18 are provided with bolt holes 20 and 22 through which bolts may pass to secure the plow and its mechanisms in place. The projections 16 and 18 extend under and beyond the front bumper of the vehicle.
Also bolted to the under structure of the truck by means not illustrated, and extending forward therefrom and below the support projections 16 and 18 is the support 24 for the plow steering mechanisms. The center of the rear of the plow blade is pivoted (by means not shown) to the support 24, and the plow is conventionally steered by means of conventional hydraulically operated pistons (not shown).
The plow elevation mechanism is conventional and it comprises an L-shaped beam 28 which carries the framework 30 which in turn supports the plow hook 32 and the hydraulically operated piston 34 which is pivoted to the beam 28 at pin 36. The beam 28 is provided with bolt holes 38 and 40, spaced apart the same distance as the bolt holes 20 and 22 on the projections 16 and 18. All of the foregoing is conventional.
Normally, the snow plow elevation control mechanism is connected directly to the projections 16 and 18 by means of bolts 41 and 42. When the plow is not needed, as in the spring, the snowplow elevation control mechanism is removed from the truck along with the elevation and steering mechanisms. However, because of its normal location below the understructure of the truck, the support arms 12 and 14 are not conveniently removed, and most snow plow operators leave those members in place winter and summer, with the projections 16 and 28 extending under and forward of the trucks bumper.
As previously noted, the projections 16 and 18 constitute a hazard to persons passing in front of the truck, and to other vehicles because these elements are located in front of and below the vehicle bumper. In order to overcome these problems, I install a cap 43 on the plow support projections 16 and 18.
The cap 43 comprises a rigid structural member which includes a top wall 44, provided with spaced bolt holes 45 and 46. The bolt holes 45 and 46 are spaced the same distance as the holes 20 and 22 in the support projections 16 and 18. The cap also includes two vertical side walls 48 and 50, interconnected by a front wall 51. The edge of the vertical sidewalls 48, 50 adjacent the front wall 51 includes a partly vertical edge 70 and a partly angled edge 71. Front wall extensions 53 incline downwardly toward the motor vehicle. In the preferred embodiment, front wall extensions 53 project from the front wall 51 at a 45.degree. angle. The front wall 51 is provided with an opening 52 to accommodate the positioning of the member 24 within the front wall of the cap.
When the plow is in place, the beam 28 of the elevation control mechanism is bolted to the projections 16 and 18 through the bolt holes 45 and 46 in the cap 43.
For improved structural stability, the cap may include bottom wall 60 and/or rear wall 62. Bottom wall 60 extends towards the truck in a plane substantially parallel to top wall 44. Rear wall 62 extends downward in a plane substantially parallel to front wall 51. Top wall 44, front wall 51, bottom wall 60 and rear wall 62 together define a hollow box shaped structure. The box shaped structure improves the inherent rigidity of the cap 43. This improved rigidity is particularly beneficial when the top wall 44 is to be used as a step or platform from which the user gains access to the difficult to reach engine compartment.
The present invention is preferably made by forming a single piece of metal, such as aluminum type 3003 into a cap of uniform thickness. Although aluminum is the preferred metal, other metals and alloys thereof can also be used as is known to those skilled in the art. Other materials such as hard plastics, composites and ceramics can also be used to form the cap according to the present invention. To provide sure footing when the user is standing on the cap, the cap surface may include diamond plate or other surface projections or attachments as is known to those skilled in the art to promote traction on flat surfaces.
In Summary
This invention provides a unique cap for the projections of a truck plow support, the cap providing a secondary bumper for the truck, a step or platform for enabling the convenient servicing of the truck's engine, a protective device and a decorative assembly which effectively conceals the unsightly projections of the plow support.
