Abstract
A side plow assembly for attaching to a motor vehicle. The side plow assembly comprises of a blade for plowing, a front plate connected to the vehicle, and a turntable for coupling the blade to the front plate. A displacement mechanism rotates the turntable about a pivot point, thereby displacing the blade between a horizontal plowing position and a vertical storage position. A rod is coupled at a first end to a distal end of the blade and at a second end to the plow. The rod maintains the blade in a predetermined position when the blade extends laterally from the vehicle.
Description
SIDE PLOW ASSEMBLY
The present invention relates generally to side plow assemblies for mounting on motor operated vehicles and the like.
BACKGROUND OF THE INVENTION
It is common practice to remove snow from streets through the use of an angled snow plow blade. Removing the snow slows down the plowing process, which is generally a slow process to begin with. A slow snow removal process is particularly undesirable when there is a high volume of traffic.
1o The angled snow plow blade channels snow away from a street side of the blade towards a curb edge of the blade. The snow is deposited as a ridge running along the curb. The snow ridge formed at the curb is generally unobjectionable and remains there until it is hauled away at a later, more convenient time, or until it melts. However, the snow ridge causes problems where it blocks laneways, driveways, adjoining streets, and the like (referred to collectively as pathways).
U.S. patent number 5,903,986 discloses a snow plow with a side gate. The side gate is employed when the snow plow passes the pathways. The gate extends from the curb 2o edge of the plow blade and momentarily stops the flow of snow from the plow blade.
The gate therefore prohibits the snow ridge from forming when it is extended.
However, since the snow is being channeled towards the gate, the force of the snow makes it difficult to extend and retract the gate. Furthermore, the snow plow as described is not the only snow plow currently in use. Thus there are still situations that require the removal of the snow ridge.
U.S. patent number 5,903,987 discloses a snow plow assembly for mounting on trucks or the like. The assembly is mounted on a side of the truck with a blade in a stored position.
The blade is extended outwardly from side of the truck to an operative position. When in 3o the operative position, the blade can clear the snow ridge from the pathways. However, since the blade is stored along the side of the truck, it is possible that the blade can come into contact with obstacles causing damage to both the blade and the obstacle.
Such obstacles include parked cars, moving cars, street signs, fire hydrants, and the like. This may be further exacerbated by the fact that when the snow plow is in use, streets are typically narrower due to the accumulation of fallen snow. Further, deploying the blade from its stored position to its operative position requires significant space for the blade to swing out. Force will also required to deploy the blade since it will have to move snow out of its way while being deployed.
It is an object of the present invention to obviate or mitigate at least some of the 1o aforementioned problems.
SUMMARY OF THE INVENTION
In accordance with the present invention, there is provided a side plow assembly for attaching to a vehicle. The side plow assembly comprises a blade for plowing, a front plate connectable to the vehicle and a turntable for coupling the blade to the front plate.
The turntable is rotatable about a pivot point. A displacement mechanism rotates the turntable. The displacement mechanism is couplable to the front plate by a first coupling and couplable to the turntable by a second coupling. A rod is couplable at a first end to the distal end of the blade and at a second end to the plow. The rod maintains the blade in a predetermined position, that is, extending laterally from the vehicle.
The turntable rotates said blade between a horizontal position and a vertical position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Refernng to Figure 1, a snow plow is illustrated generally by the numeral 10.
The snow plow includes a front plate 12 connected to a front of a vehicle 11. A
turntable 18 is located at one end of the front plate 12, preferably at an end of the front plate 12 that is closer to a curb 13. The turntable 18 is pivotable about a pivot point 19, which is preferably at a center of the turntable 18. A raised central plate 30 is secured to the turntable 18 and supports a connected crank arm 16. The crank arm 16 lies in a plane that is parallel and off set to the turntable 18. The turntable 18 is rotated by a hydraulic cylinder 14, which is connected between the crank arm 16 and the front plate 12. A first pin joint 22 is used to connect the crank arm 16 to one end of the hydraulic cylinder 14 and a second pin joint 24 is used to connect another end of the hydraulic cylinder to a plate 31, which is secured to the front plate 12. The turntable 18, connected central plate 30, and the plate 31 are proportioned so that the hydraulic cylinder 14 lies in the same plane as the crank arm 16. Attached to the turntable is a blade 20. The hydraulic cylinder 14 cooperates with the crank arm 16 to pivot the turntable 18 about the pivot 2o point 19. In this manner, the attached blade 20 is displaced between a stored position shown in Figure 1 and an operative position shown in Figure 2.
Referring to figure 3, an exploded view of the blade 20 is shown. The bottom of the blade 20 is coupled to a boom 32 using several nut and bolt assemblies 34. A
hinge 35 is formed by a pair of bores 46 attached to a proximate end of the boom 32 and a pair of bores 46 attached to the turntable 18 via a pair of plates 47, which are welded to the central plate 30. A pin 48 is inserted through the bores 46 for hingedly attaching the boom 32 to the turntable 18 and serves as an axis of rotation for the hinge 35, as the blade 20 swings between the operative and stored positions. An elongate, spring-loaded push 3o rod 36 extends along the side of the snow plow and is coupled between a snow plow stabilizer (not shown) and a distal end of the boom 32. The stabilizer is typically located at the rear of the snow plow 10. The push rod 36 has a ball and socket joint 38 at each end so that the blade 20 can be swung between the operative and stored positions, without disconnecting the push rod 36. The push rod 36 includes two telescoping rods 40, 42.
The first rod 40 has a pair of pinholes 44 and the second rod 42 has several pairs of pinholes 44. The length of the push rod 36 is adjusted by aligning the pair of pinholes 44 on the first rod 40 with one of the pairs of pinholes 44 on the second rod 42.
A pin is inserted through the pinholes 44 for maintaining the length of the push rod 36.
Since the blade 20 is hingedly attached to the turntable 18, it is possible for the blade 20 to rotate about the axis defined by the hinge 35. Therefore, the push rod 36 is employed to maintain the blade 20 at a fixed angle relative to the plates 47, once the blade 20 is placed in either the operative or stored position. The push rod 36 is spring-loaded for providing shock absorption for the blade 20, when placed in the operative position.
Thusly, there is some variation allowed in the angle maintained by the push rod 36, although this angle typically does not change by more than a few degrees during plowing.
The length of the push rod 36 can be easily modified as described above for adjusting the angle between the blade 20 and the plates 47. The longer the push rod 36, the further forward the distal end of the blade will lie. Therefore, adjusting the length of the push rod 36 changes the direction the snow is plowed. Furthermore, the push rod 36 is of sufficient length in combination with the flexible hinge 35, so that warping of the push rod 36 is negligible as the blade 20 moves between the operative and stored positions.
Referring to figure 4, the rear of the blade 20 is shown in its operative position. The top of the blade 20 is attached to the boom 32 via several springs 50. The springs 50 are in a typically in a relaxed state, and the blade 20 is in a generally upright position. 'Che bottom of the blade 20 is attached to the boom 32 via the nut and bolt assemblies 34, as shown in figure 3. The blade 20 is capable of rotating about the nut and bolt assemblies 34, but is held in place by the springs 50. If the blade 20 hits a raised obstruction while it 3o is plowing, the blade 20 pivots slightly forward, extending the springs 50.
Once the obstruction is passed, the springs 50 force the blade 20 to return to the upright position.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Refernng to Figure 1, a snow plow is illustrated generally by the numeral 10.
The snow plow includes a front plate 12 connected to a front of a vehicle 11. A
turntable 18 is located at one end of the front plate 12, preferably at an end of the front plate 12 that is closer to a curb 13. The turntable 18 is pivotable about a pivot point 19, which is preferably at a center of the turntable 18. A raised central plate 30 is secured to the turntable 18 and supports a connected crank arm 16. The crank arm 16 lies in a plane that is parallel and off set to the turntable 18. The turntable 18 is rotated by a hydraulic cylinder 14, which is connected between the crank arm 16 and the front plate 12. A first pin joint 22 is used to connect the crank arm 16 to one end of the hydraulic cylinder 14 and a second pin joint 24 is used to connect another end of the hydraulic cylinder to a plate 31, which is secured to the front plate 12. The turntable 18, connected central plate 30, and the plate 31 are proportioned so that the hydraulic cylinder 14 lies in the same plane as the crank arm 16. Attached to the turntable is a blade 20. The hydraulic cylinder 14 cooperates with the crank arm 16 to pivot the turntable 18 about the pivot 2o point 19. In this manner, the attached blade 20 is displaced between a stored position shown in Figure 1 and an operative position shown in Figure 2.
Referring to figure 3, an exploded view of the blade 20 is shown. The bottom of the blade 20 is coupled to a boom 32 using several nut and bolt assemblies 34. A
hinge 35 is formed by a pair of bores 46 attached to a proximate end of the boom 32 and a pair of bores 46 attached to the turntable 18 via a pair of plates 47, which are welded to the central plate 30. A pin 48 is inserted through the bores 46 for hingedly attaching the boom 32 to the turntable 18 and serves as an axis of rotation for the hinge 35, as the blade 20 swings between the operative and stored positions. An elongate, spring-loaded push 3o rod 36 extends along the side of the snow plow and is coupled between a snow plow stabilizer (not shown) and a distal end of the boom 32. The stabilizer is typically located at the rear of the snow plow 10. The push rod 36 has a ball and socket joint 38 at each end so that the blade 20 can be swung between the operative and stored positions, without disconnecting the push rod 36. The push rod 36 includes two telescoping rods 40, 42.
The first rod 40 has a pair of pinholes 44 and the second rod 42 has several pairs of pinholes 44. The length of the push rod 36 is adjusted by aligning the pair of pinholes 44 on the first rod 40 with one of the pairs of pinholes 44 on the second rod 42.
A pin is inserted through the pinholes 44 for maintaining the length of the push rod 36.
Since the blade 20 is hingedly attached to the turntable 18, it is possible for the blade 20 to rotate about the axis defined by the hinge 35. Therefore, the push rod 36 is employed to maintain the blade 20 at a fixed angle relative to the plates 47, once the blade 20 is placed in either the operative or stored position. The push rod 36 is spring-loaded for providing shock absorption for the blade 20, when placed in the operative position.
Thusly, there is some variation allowed in the angle maintained by the push rod 36, although this angle typically does not change by more than a few degrees during plowing.
The length of the push rod 36 can be easily modified as described above for adjusting the angle between the blade 20 and the plates 47. The longer the push rod 36, the further forward the distal end of the blade will lie. Therefore, adjusting the length of the push rod 36 changes the direction the snow is plowed. Furthermore, the push rod 36 is of sufficient length in combination with the flexible hinge 35, so that warping of the push rod 36 is negligible as the blade 20 moves between the operative and stored positions.
Referring to figure 4, the rear of the blade 20 is shown in its operative position. The top of the blade 20 is attached to the boom 32 via several springs 50. The springs 50 are in a typically in a relaxed state, and the blade 20 is in a generally upright position. 'Che bottom of the blade 20 is attached to the boom 32 via the nut and bolt assemblies 34, as shown in figure 3. The blade 20 is capable of rotating about the nut and bolt assemblies 34, but is held in place by the springs 50. If the blade 20 hits a raised obstruction while it 3o is plowing, the blade 20 pivots slightly forward, extending the springs 50.
Once the obstruction is passed, the springs 50 force the blade 20 to return to the upright position.
This feature further enhances the shock absorbing quality provided by the spring-loaded push rod 36. Allowing the blade 20 to pivot reduces the possibility of damaging the blade 20 by imparting some of the momentum of impacting obstructions from the blade 20 to the springs 50.
The front plate 12 and turntable 18 are preferably made of steel and are further illustrated in figures 5 and 6. A rear surface 50 of the turntable 18 is in general contact with the front plate 12. A set of brackets 52 are fastened to the front plate 12, and are slidably connected to the front surface 53 of the turntable 18. A sacrificial wear plate 54 can be 1o interposed between the brackets 52 and the surface 53, which permit slidable displacement between the turntable 18 and the brackets 52. The material of the wear plate 54, such as brass, can be chosen so that wear damage to the surface 53 is minimized during rotation of the turntable 18 about the pivot point 19.
The nut and bolt assembly 51 of the pivot point 19 further includes a shaft 58, a bolt 60, and bearings 64. The bearings 64 allow rotation of turntable 18 about the shaft 58.
Therefore, the nut and bolt assembly 51 operatively couples the turntable 18 to the front plate 12. Once coupled, clearance between the rear surface 50 of this turntable and the front plate 12 is minimized, so that bending stresses on the shaft 58 is inhibited.
If the vehicle maintains the blade 20 in the stored position for extended periods, the actuator 14 is the only device preventing the blade 20 from falling and may fail.
Therefore, a chain 56 can be temporarily connected between the vehicle frame 58 and the blade 20, for locking the blade 20 while it is in the stored position. The chain 56 can be used to reduce stress on the actuator 14, if desired.
Refernng once again to figure 1, the hydraulic cylinder 14 is not extended and the blade 20 is in a generally vertical stored position. The width of the blade 20 is preferably stored within the track of the snow plow 10, although this is not necessarily true.
3o Further, the blade 20 is preferably stored such that it is not directly in front of a driver.
Therefore, the driver has a sufficient view for driving safely.
The front plate 12 and turntable 18 are preferably made of steel and are further illustrated in figures 5 and 6. A rear surface 50 of the turntable 18 is in general contact with the front plate 12. A set of brackets 52 are fastened to the front plate 12, and are slidably connected to the front surface 53 of the turntable 18. A sacrificial wear plate 54 can be 1o interposed between the brackets 52 and the surface 53, which permit slidable displacement between the turntable 18 and the brackets 52. The material of the wear plate 54, such as brass, can be chosen so that wear damage to the surface 53 is minimized during rotation of the turntable 18 about the pivot point 19.
The nut and bolt assembly 51 of the pivot point 19 further includes a shaft 58, a bolt 60, and bearings 64. The bearings 64 allow rotation of turntable 18 about the shaft 58.
Therefore, the nut and bolt assembly 51 operatively couples the turntable 18 to the front plate 12. Once coupled, clearance between the rear surface 50 of this turntable and the front plate 12 is minimized, so that bending stresses on the shaft 58 is inhibited.
If the vehicle maintains the blade 20 in the stored position for extended periods, the actuator 14 is the only device preventing the blade 20 from falling and may fail.
Therefore, a chain 56 can be temporarily connected between the vehicle frame 58 and the blade 20, for locking the blade 20 while it is in the stored position. The chain 56 can be used to reduce stress on the actuator 14, if desired.
Refernng once again to figure 1, the hydraulic cylinder 14 is not extended and the blade 20 is in a generally vertical stored position. The width of the blade 20 is preferably stored within the track of the snow plow 10, although this is not necessarily true.
3o Further, the blade 20 is preferably stored such that it is not directly in front of a driver.
Therefore, the driver has a sufficient view for driving safely.
When the hydraulic cylinder 14 is extended, the crank arm 16 and the turntable 18 are rotated. The blade 20 is lowered into a generally horizontal operative position as shown in figure 2. The pivot axis for the blade is the pivot point 19 on the turntable 18. When in the operative position, the blade 20 extends laterally from the snow plow 10. Since the hydraulic cylinder 14 and the crank arm 16 lie in a plane offset to that of the raised plate 30, the hydraulic cylinder 14 will not inhibit rotation of the turntable 18 or the plate 30 as the cylinder 14 extends.
Furthermore, in an alternative embodiment, a second snow plow blade (not to shown) can be attached to the front plate 12 for removing snow from a street. The second blade can be an angled blade, if desired.
Although the invention has been described with reference to certain specific embodiments, various modifications thereof will be apparent to those skilled in the art without departing from the spirit and scope of the invention as outlined in the claims appended hereto.
Furthermore, in an alternative embodiment, a second snow plow blade (not to shown) can be attached to the front plate 12 for removing snow from a street. The second blade can be an angled blade, if desired.
