Abstract
A mounting device for connection of objects to a vehicle frame has a vehicle mount assembly secured to the frame which has hollow tubes projecting toward the forward end of the vehicle to engage posts on a connection assembly. In addition to having posts for the connection to the mount assembly, the connection assembly is suited for connection to personal use devices that are to be mounted on the vehicle, such as a snow plow, bicycle carrier, trailer shepherd or other object. Once the object is attached to the connection assembly and the posts of the connection assembly are engaged in the tubes of the mounting assembly, the posts and tubes are locked together for safety. To assist in lifting an object such as a snow plow to a height and position so that the posts of the connection assembly align with the tubes of the vehicle mounting assembly, a dolly has a parallel linkage assembly for easy raising and lowering of a load. The mounting device provides a simple, easy to use and easy to mount means of releasably securing objects to a vehicle frame, without significantly altering or reinforcing the frame.
Description
~125414 '_ 1 Vehicle Frame Mount for Snow Plow or the Like This invention relates to a mounting device for connection to a vehicle and a snow plow for connection to a vehicle or a vehicle mounting device. More particularly, the invention relates to a device for mounting a snow plow for use with a light truck or utility vehicle, an improved manner of controlling and directing the operation of a blade of a snow plow and a light, personal use snow plow for connection to a vehicle.
Background of the Invention During winter months in northern climates snow removal is of great concern, and it has developed that personal snow plows are used on trucks and recreational vehicles. Due to the seasonality of snow plowing, the dangers of driving a vehicle with a snow plow attached and the aesthetically unpleasing nature of the plow, it is preferred that the snow plow be removable. Detachable plows have been developed, however, the vehicle mount for attaching the plow remains on the vehicle, and is itself unpleasing to look at. Further, such plows are heavy and awkward to mount, and often require more than one person and tools to achieve a proper connection.
The vehicle mount for such recreational vehicles is generally attached by reinforcing the frame and bumper members of the vehicle, and generally remain connected to the vehicle in the off season. The reinforcement of the frame and bumper of the vehicle is necessitated by the heavy weight of the plow, and the stress carried over to the vehicle during the plowing of snow and ice, and the bumps and solid objects struck during plowing.
The presence of the vehicle mount, and the evidence of attachment, such as drilling, welding and other frame modifications, of such vehicle mounts once removed also reduces the value of a recreational vehicle on resale.
This is also true since the repeated use of a ~125414 _ 2 recreational vehicle for heavy plowing may stress the vehicle frame and bumper.
For the foregoing reasons it will be seen that there is a need for a mount assembly to support a light, personal use snow plow that is connectable to a vehicle frame without damaging or significantly altering the frame or bumper, and which is aesthetically pleasing and easy to mount and use. It is also evident that a snow plow that is itself easily mountable and connectable to a vehicle mount assembly and adapted well to personal use is needed.
Summary of the Invention The present invention is directed to a vehicle mount apparatus and a snow plow for connection to the mount or other mounts that satisfies the need for a vehicle mount that is strong and aesthetically pleasing and supports a detachable snow plow designed for personal use.
Accordingly, in one aspect of the invention an attachment system is comprised of a vehicle mount assembly and a connection assembly. The vehicle mount assembly has a base, mount arms attached to the base and spaced apart a selected distance, and connectors attached to the base for connecting the base to the vehicle frame.
The mount arms are supported above the ground and substantially under the vehicle. The connection assembly comprises a base and connection arms attached to the base and spaced apart a selected distance. The mount arms and the connection arms are selectively lockably engageable and disengageable, and the spaced apart distance between the mount arms and the connection arms is selected to allow engagement and disengagement of the arms.
In another aspect of the invention, an attachment system comprises a vehicle frame mount assembly and a connection assembly. The vehicle frame mount assembly comprises an elongate bar, at least two spaced apart mounting arms provided on the bar, and frame connection brackets attached to the bar. The connection brackets - 212~414 _ 3 have means for connecting the brackets to the frame. The bar and the connection brackets are adapted for supporting the mount arms under the vehicle without interfering with the operation of the vehicle. The connection assembly comprises spaced apart connection arms for cooperation and engagement with the mount arms.
The connection assembly is attachable to an object to be mounted on the vehicle.
In a further aspect of the invention, a mount assembly for connection to a support and for use with an object connection assembly is provided. The mount assembly comprises a base, mount arms attached to the base and spaced apart a selected distance and connectors attached to the base for connecting the base to the support. The mount arms are selectively lockingly engageable and disengageable with the object connection assembly. A further aspect of the invention provides a connection assembly having a base, connection arms attached to the base and spaced apart a selected distance, and attachment means for attaching an object to the connection assembly. The connection assembly and the mount assembly are selectively lockingly engageable.
Further, the connection assembly and the mount assembly just described form a kit that is a further aspect of the invention.
An additional aspect of the invention is a plow assembly for attachment to a blade. The plow has a supporting base, a sliding member connected to and slidable on the base along an arc, a blade connected to a forward end of the slidable member and movable along an arc upon sliding movement of the slidable member, and connection means for connecting the plow to the vehicle and operably supporting the plow for use.

Detailed Description In a preferred embodiment of the invention, illustrated in Figures 1 and 2, the snow plow assembly (generally referred to at 2) attaches to a connection or receiver assembly shown generally at 3. The connection assembly 3 attaches to a vehicle by being fitted on a vehicle mount assembly shown generally at 4. The mount assembly 4 is shown fixed to frame 6 of a vehicle. The plow has a frame 18 to which winch 10 is attached to allow powered lifting and lowering of the plow blade 12 once mounted on the vehicle. The winch is powered by connection to the vehicle battery (not shown). A hoop assembly 14 is provided on the forward end of the plow frame for horizontal movement and angling of the blade 12 in a desired direction.
Referring to Figure 3, in which the plow assembly 2 is shown in greater detail, a T-frame assembly 16 has a T-shaped frame having a base 20 and an extension 22 with an attachment member such as closed loop 23 at an end remote from the base. The opposed ends of the base 20 have plates 24,26 attached thereto for connection of the connection assembly 3 to the T-frame 16. The connection assembly 3 has connection or receiving arms such as hollow tubes 30,30 with open end 32 for receiving the mount arms 5 (one shown in dotted outline) of the vehicle mount assembly. Aligned openings 36 in the wall of tube 30 are provided to receive a fastener such as a pin or hitch pin 38 to lock the receiving arms in engagement with the mount arms.
To connect tubes 30 to the T-frame 16, brackets _ 6 40,40 are fixed to the tubes 30,30 and the brackets are fastened to the plates 24,26 using fasteners such as bolts 42,42 and nuts (not shown) which connect the brackets and plates using openings 44,46,47 provided.
Each bracket has one additional opening 48 for receiving A-frame/connection assembly pivot pin 50 (shown on one bracket only).
Referring to Figures 3 and 4A, the base or A-frame 18 is formed by three arms 52,54,56 arranged in a triangle, with a plate 57 fastened to the frame at the top of the A-frame where the arms 54,56 form a corner. A
cross brace or support arm 58 is connected to arms 54,56 near the base of the A-frame, near the corners that arms 54,56 form with arm 52. To ensure proper alignment of sliding hoop 14, the hoop has bars 68 and the bars have an opening (not shown) that aligns with opening 58a in plate 57 attached to the arms 54,56 of the frame. A
fastener 57b is placed through the openings to allow pivoting movement of the hoop on the frame. Also, hoop rotation guides 59,59 are fixed to the A-frame 14 so that the edge 15 of the hoop 14 slides under the hoop rotation guides 59 and the guides 59 hold the hoop against undesired rearward and upward movement. The movement of the hoop 14 follows an arc and is substantially horizontal when the plow is in plowing position. To lock the hoop 14 in a selected position, a centrally placed opening 60 is provided on A-frame cross-brace 58 and corresponding plow blade angle control openings 62 are provided on the hoop 14. A fastener such as bolt 64 may be placed through opening 62 aligned with opening 60 to lock the hoop in a selected position. Alternatively, a hands-free angling and fastening method may be used, where a spring loaded fastener 59 (shown in Figure 4B) is dropped into position in angle control opening 62 when it aligns with opening 60 in cross-brace 58. The alignment may be achieved using a foot operated pedal 63a, 63b provide on bar 63 to slide the hoop into a desired position so that the fastener 59, which is provided on bar 61, may drop into opening 60 to lock the hoop in position. Spring assemblies 61,61 are provided to hold the fastener in opening 60, and to act as a stop mechanism when pressure is applied to either pedal 63a, 63b and the fastener 59 is removed from the opening 60.
Referring again to Figure 3, to allow up and down pivoting of the blade 12 of plow assembly 2, the hoop 14 has a series of three blade mounts 66 provided on bars 68 connected to opposed ends of the hoop 14. The blade mounts 66 have spaced apart and opposed plates 69 with aligned openings 70, so that a fastener such as clevis pin 76 is slidable in the openings 70,74 to lock the blade to the hoop and allow up and down pivoting motion.
A winch 10 powered by the vehicle electrical system is supported by and attached to plate 57 and is connected to loop 23 on extension 22 for raising and lowering the blade.
The blade may be any size or contour according to the work to be done, and has a scraper 77 on its ground engaging lower surface. The blade 12 is pivotally connected to the hoop of the plow assembly to allow the blade to trip forward if it encounters an obstacle during plowing. To return the plow blade back to plowing position a pair of springs 80 are connected between the blade 12 and the hoop 14, symmetrical about the centre line of the blade and hoop. To connect the spring to the blade and the hoop, spring hook 82 on one end of spring 80 fits into the opening in eye bolt 84 fixed to the top of blade 12, and spring hook 82 on opposite end of spring 80 engages the hoop through opening 83 in the side of the hoop. Finally, side markers 88 may be fastened to sides of blade 12 to act as guides.
Referring to Figure 5, in which the vehicle mount assembly 4 is shown in greater detail, the bar 100 supporting spaced mount arms 5 connected thereto has connection brackets 102 fixed to the bar 100 for fixing ` 2125414 _ 8 the entire assembly to the frame of a vehicle. The vehicle mount assembly which as shown is comprised of the bar 100, the mount arms 5 and the brackets 102 may be entirely made of steel, as a single piece or as parts assembled together. To prevent premature wear and aging, the assembly may be coated with a protective finish.
The mount arms 5 are spaced apart a distance selected to cooperate with the receiving arms 30 of the connection assembly. The mount arms may be hollow or solid, and are of a shape to slide into the receiving arms 30. Aligned openings 104 in each mount arm 5 align with openings 36 in each hollow tube receiving arm 30 so that hitch pin 38 may lockingly engage the mount and receiving arms to prevent disengagement during use.
To connect the vehicle mounting assembly to the vehicle frame certain obstacles must be overcome. The brackets are designed to be connected to the body frame of the vehicle at a point where the frame has about 12 inches or more of support along the frame, or as much as is necessary to prevent undesired bending or kinking of the frame. At the same time, the connection must be sufficient to support the mount arms at a height above the ground of about 12 inches, or as high as necessary to engage the receiving arms of the connection assembly and allow for operation or transport of the plow or other device connected to the connection assembly.
For use with the snow plow described herein, the mount arms are preferably 31 inches apart and supported about 12 inches off the ground. When designing the brackets and bar, it is important to ensure that the brackets and bar and any other members do not interfere with springs, steering column, or other vehicle parts.
Accordingly, a single vehicle mounting assembly will not accommodate all vehicles, but these guidelines will assist in determining the shape of the bar and the form and number of brackets and support plates that will be required to provide a vehicle mounting assembly for g connection to a light truck or recreational four-wheel-drive vehicle.
Figure 5 also illustrates the connection of the vehicle mount assembly to a vehicle frame, and is an example of a typical connection. The illustration indicates in particular the connection of the vehicle mount assembly to the frame of a vehicle sold under the trade mark F150, model years 1991 to 1994.
A further example of an embodiment of the connection of the vehicle mount assembly to the frame of a vehicle sold under the trade-mark GMC S-Jimmy, model years 1982-1994, is shown in Figures 6A and 6B. Referring to Figure 6A, the bar 100' supporting spaced mount arms 5 has side walls forming connection brackets 102' for fixing the entire assembly to the vehicle frame. Referring to Figure 6B, the vehicle mount assembly 4 is shown in position for connection to the frame 6 of the vehicle.
In performing the attachment, any tow hooks (not shown) on the vehicle are removed and threaded tow hook supports 180 are inserted through the front of the frame. The mount assembly 4 is loosely attached to the frame by fasteners 182 which join the frame 6, the threaded tow hook supports 180 and bracket 102' via openings 181 and 184. To secure the connection, a support arm 186 has one end fixed to plate 103' on vehicle mount assembly 4 and another end fixed to frame 6, such as by fasteners 188,189. This attachment may be made first on the passenger side of the vehicle and then on the driver side of the vehicle. A U-bolt assembly 190,191 encircles a portion of the frame 6 and bracket 102' to secure the connection. Additionally, flange 102a abuts raised portion 192 on plate 191 of the U-bolt assembly to prevent slippage and to further secure the connection.
It will be seen that vehicle parts or accessories connected to the frame may have to be removed to achieve the connection, and holes (not shown) for receiving fasteners may have to be made in the frame. Also, since 212541~
vehicle frames may differ in configuration of their sides, the angle of the mounting arms 5 may not be horizontal, and shims (not shown) may be required to correct the angle of the mounting arms 5 so they are horizontal for proper reception of the connection assembly 3 for supporting a desired object, such as the plow described herein.
Referring again to Figure 3, the plow is pivotally connected to the connection assembly by pivot pin 50 which engages the A-frame 18. The winch supported on plate 57 is connected to the closed loop 23 on extension 22 of the T-frame 20 of the connection assembly 3 for raising and lowering the blade 12 of the plow. For power the winch is connected to the electrical system of the vehicle, and a remote control (not shown) may be used by the driver of the vehicle.
As shown in Figure 4A, to direct the snow at a particular angle, the blade is angled by moving the sliding hoop 14 along its arc of movement to a desired position where an opening 62 on the sliding hoop 14 is aligned with the central opening 60 in the brace arm 52 connected to the A-frame and a pin 64 is passed through the aligned openings to lock the hoop, and thus the blade, in position. As shown in Figure 4B, if the hands-free spring-loaded fastener assembly is used, thew operator steps on one of pedals 63a,63b and releases the pedal to allow fastener 59 to enter opening 60 to secure the hoop in desired position. The plow is now ready for use, and includes a forward trip mechanism so that if obstacles are encountered during plowing the blade will pivot forward to avoid damage to the plow. Springs 80 are provided to trip the blade back into plowing position once the obstacle is removed.
For ease of mounting and connection of the plow to the vehicle, a dolly may be used. Referring to Figure 7A, an embodiment of a dolly is shown generally at 110.
The dolly acts as a storage stand for the plow or other - 212S~14 object when it is not in use, and is raisable to and lowerable from a mounting height to align the hollow tubes 30 of the connection assembly 3 with the mounting arms 5 on the mounting assembly 4. The dolly has a base 112, two support arms 114,115 and a linkage assembly 116.
The arms 114 and 115 have one end fastened to the base by fasteners 120, and project in substantially a V-shape in a direction away from the base 112. At the other end of each arm 114,115, a caster support 119 is fastened to the arm for attachment of caster wheel 118. The base 112 acts as a support for objects rested on the dolly 110, and the arms have a surface 121 for supporting parts of the supported object, such as a plow blade of a plow.
Base extensions 113 may assist in supporting an object on the base 112.
The linkage assembly 116 has paired parallel link arms 122,124 pivotally connected at one end to the base and at the other end to the caster support 119. The connection to the caster support 119 is effected by pivotally fastening the link arms 122,124 to brackets 126,128 on the caster support 119, using fasteners 130 in aligned openings (not shown) on the brackets and the link arm. The other end of each link arm is pivotally connected to brackets 132, 134 on the base 112 by fasteners 136 in aligned openings (not shown) on the brackets and the link arm. A removable handle 138 has a channel 140 for receiving a connector portion 142 of the linkage assembly 116. By causing one of the link arms to move in an arc toward or away from the base, the linkage assembly will lower or raise the base 112 and any object on the base. The handle 138 may be used to push the dolly or as a lever to lift the parallel links 122,124 and raise and lower the base 112, and thus raise and lower a plow or other object on the dolly.
The position of the base may also be adjusted according to the desired height of the dolly for receiving an object to be supported. The arc through which the link arms may move, the length of the arms 114,115 and link arms 122,124 may be adjusted according to the object to be supported and the desired range of adjustment in height of the base 112.
Referring to Figure 7B, another embodiment of the dolly is shown generally at 110'. This alternative embodiment has a base 112', base extensions 113' two support arms 114,115'and a lift arm 116'. The support arms 114',115' have one end fastened to the base 112', such as by fasteners 120', and projected in substantially a V-shape away from the base 112'. A caster support 119' with wheel 118' isttached to the free end of each arm 114',115'. One end of lift arm 116' is pivotally connected to the base 112' by fastener 120' passed through openings llla in walls 111, and openings lllb (only one shown) in lift arm 116'. A caster support 119' with wheel 118' is connected to the other end of lift arm 116'. A connector portion 142' is provided on the lift arm 116' to form a T-shape with the left arm, and is of a shape and diameter to be received and engaged by a removable handle 138' with channel 140' for making the connection. The handle 138', once connected to the connector portion 142', is used as a lever to lift and lower the base 112' by pivoting the lift arm 116 in its connection to the base 112'.
It will be seen that the light personal use plow and the connection and mounting assemblies described herein provide easy mounting and dismounting of the plow relative to a vehicle.
It will be seen that the vehicle mount described herein may be used for other purposes than supporting a plow and, for example, a trailer shepherd, a bicycle carrier, a rotating brush assembly or other objects and devices may be connected to the connection assembly and then attached to the vehicle using the vehicle mount assembly.
Referring to Figure 8, in an embodiment of a bicycle _ 13 carrier 150 for attachment to a connection assembly 3', the bicycle carrier has opposed gripping plates 152,153 for holding the frame of a bicycle, and is attached to a column support 154. The connection assembly 31 has a V-shaped bar 160, and at each free end 161,161 a hollowtube 30 is provided. The support 154 has a coupling arm 156 for coupling the bicycle carrier 150 to connection assembly 3'. To allow the attachment, at the centre of the V-shaped bar 162 of the connection assembly 3' is provided a support surface 162, and an inverted channel member 163 is fastened to the surface, such as by fasteners 164. The coupling arm 156 slides into channel 166, and aligned fasteners (not shown) are slid into aligned openings 158 (shown on one side only of the coupling arm) and 168 (shown on one side only of the channel member) to secure the connection. It will be seen that the connection assembly 3' is as described herein in regard to connection assembly 3, particularly in the spacing and positioning of the hollow tubes 30.
The vehicle mount assembly 4 (not shown in this view) is unchanged. The connection assembly 3' is releasably lockably secured to the vehicle mount assembly 4 as previously described.
Referring to Figure 9, in an embodiment of a trailer shepherd 170 for attachment to the connection assembly 3', the trailer shepherd comprises a ball 174 fixed to surface 162 of the U-shaped bar 160 of connection assembly 3'. The ball 174 is fixed to the bar 160 for directly or indirectly hitching a trailer or another such device to the trailer shepherd 170.
It will also be seen that the plow described and claimed herein may be adapted for connection to vehicles with other types of vehicle mounts, and its description in use with the vehicle mount and connection assembly described is not intended to be limiting.
Accordingly, although the invention has been described with reference to preferred embodiments, it is - 212~414 _ 14 obvious that variations and modifications within the skill of a person in the art may be made without departing from the spirit and scope of the invention which is defined by the appended claims.
Background of the Invention During winter months in northern climates snow removal is of great concern, and it has developed that personal snow plows are used on trucks and recreational vehicles. Due to the seasonality of snow plowing, the dangers of driving a vehicle with a snow plow attached and the aesthetically unpleasing nature of the plow, it is preferred that the snow plow be removable. Detachable plows have been developed, however, the vehicle mount for attaching the plow remains on the vehicle, and is itself unpleasing to look at. Further, such plows are heavy and awkward to mount, and often require more than one person and tools to achieve a proper connection.
The vehicle mount for such recreational vehicles is generally attached by reinforcing the frame and bumper members of the vehicle, and generally remain connected to the vehicle in the off season. The reinforcement of the frame and bumper of the vehicle is necessitated by the heavy weight of the plow, and the stress carried over to the vehicle during the plowing of snow and ice, and the bumps and solid objects struck during plowing.
The presence of the vehicle mount, and the evidence of attachment, such as drilling, welding and other frame modifications, of such vehicle mounts once removed also reduces the value of a recreational vehicle on resale.
This is also true since the repeated use of a ~125414 _ 2 recreational vehicle for heavy plowing may stress the vehicle frame and bumper.
For the foregoing reasons it will be seen that there is a need for a mount assembly to support a light, personal use snow plow that is connectable to a vehicle frame without damaging or significantly altering the frame or bumper, and which is aesthetically pleasing and easy to mount and use. It is also evident that a snow plow that is itself easily mountable and connectable to a vehicle mount assembly and adapted well to personal use is needed.
Summary of the Invention The present invention is directed to a vehicle mount apparatus and a snow plow for connection to the mount or other mounts that satisfies the need for a vehicle mount that is strong and aesthetically pleasing and supports a detachable snow plow designed for personal use.
Accordingly, in one aspect of the invention an attachment system is comprised of a vehicle mount assembly and a connection assembly. The vehicle mount assembly has a base, mount arms attached to the base and spaced apart a selected distance, and connectors attached to the base for connecting the base to the vehicle frame.
The mount arms are supported above the ground and substantially under the vehicle. The connection assembly comprises a base and connection arms attached to the base and spaced apart a selected distance. The mount arms and the connection arms are selectively lockably engageable and disengageable, and the spaced apart distance between the mount arms and the connection arms is selected to allow engagement and disengagement of the arms.
In another aspect of the invention, an attachment system comprises a vehicle frame mount assembly and a connection assembly. The vehicle frame mount assembly comprises an elongate bar, at least two spaced apart mounting arms provided on the bar, and frame connection brackets attached to the bar. The connection brackets - 212~414 _ 3 have means for connecting the brackets to the frame. The bar and the connection brackets are adapted for supporting the mount arms under the vehicle without interfering with the operation of the vehicle. The connection assembly comprises spaced apart connection arms for cooperation and engagement with the mount arms.
The connection assembly is attachable to an object to be mounted on the vehicle.
In a further aspect of the invention, a mount assembly for connection to a support and for use with an object connection assembly is provided. The mount assembly comprises a base, mount arms attached to the base and spaced apart a selected distance and connectors attached to the base for connecting the base to the support. The mount arms are selectively lockingly engageable and disengageable with the object connection assembly. A further aspect of the invention provides a connection assembly having a base, connection arms attached to the base and spaced apart a selected distance, and attachment means for attaching an object to the connection assembly. The connection assembly and the mount assembly are selectively lockingly engageable.
Further, the connection assembly and the mount assembly just described form a kit that is a further aspect of the invention.
An additional aspect of the invention is a plow assembly for attachment to a blade. The plow has a supporting base, a sliding member connected to and slidable on the base along an arc, a blade connected to a forward end of the slidable member and movable along an arc upon sliding movement of the slidable member, and connection means for connecting the plow to the vehicle and operably supporting the plow for use.
In a further aspect, a dolly for use with the attachment system has a base for supporting an object to be mounted or dismounted.

Detailed Description In a preferred embodiment of the invention, illustrated in Figures 1 and 2, the snow plow assembly (generally referred to at 2) attaches to a connection or receiver assembly shown generally at 3. The connection assembly 3 attaches to a vehicle by being fitted on a vehicle mount assembly shown generally at 4. The mount assembly 4 is shown fixed to frame 6 of a vehicle. The plow has a frame 18 to which winch 10 is attached to allow powered lifting and lowering of the plow blade 12 once mounted on the vehicle. The winch is powered by connection to the vehicle battery (not shown). A hoop assembly 14 is provided on the forward end of the plow frame for horizontal movement and angling of the blade 12 in a desired direction.
Referring to Figure 3, in which the plow assembly 2 is shown in greater detail, a T-frame assembly 16 has a T-shaped frame having a base 20 and an extension 22 with an attachment member such as closed loop 23 at an end remote from the base. The opposed ends of the base 20 have plates 24,26 attached thereto for connection of the connection assembly 3 to the T-frame 16. The connection assembly 3 has connection or receiving arms such as hollow tubes 30,30 with open end 32 for receiving the mount arms 5 (one shown in dotted outline) of the vehicle mount assembly. Aligned openings 36 in the wall of tube 30 are provided to receive a fastener such as a pin or hitch pin 38 to lock the receiving arms in engagement with the mount arms.
To connect tubes 30 to the T-frame 16, brackets _ 6 40,40 are fixed to the tubes 30,30 and the brackets are fastened to the plates 24,26 using fasteners such as bolts 42,42 and nuts (not shown) which connect the brackets and plates using openings 44,46,47 provided.
Each bracket has one additional opening 48 for receiving A-frame/connection assembly pivot pin 50 (shown on one bracket only).
Referring to Figures 3 and 4A, the base or A-frame 18 is formed by three arms 52,54,56 arranged in a triangle, with a plate 57 fastened to the frame at the top of the A-frame where the arms 54,56 form a corner. A
cross brace or support arm 58 is connected to arms 54,56 near the base of the A-frame, near the corners that arms 54,56 form with arm 52. To ensure proper alignment of sliding hoop 14, the hoop has bars 68 and the bars have an opening (not shown) that aligns with opening 58a in plate 57 attached to the arms 54,56 of the frame. A
fastener 57b is placed through the openings to allow pivoting movement of the hoop on the frame. Also, hoop rotation guides 59,59 are fixed to the A-frame 14 so that the edge 15 of the hoop 14 slides under the hoop rotation guides 59 and the guides 59 hold the hoop against undesired rearward and upward movement. The movement of the hoop 14 follows an arc and is substantially horizontal when the plow is in plowing position. To lock the hoop 14 in a selected position, a centrally placed opening 60 is provided on A-frame cross-brace 58 and corresponding plow blade angle control openings 62 are provided on the hoop 14. A fastener such as bolt 64 may be placed through opening 62 aligned with opening 60 to lock the hoop in a selected position. Alternatively, a hands-free angling and fastening method may be used, where a spring loaded fastener 59 (shown in Figure 4B) is dropped into position in angle control opening 62 when it aligns with opening 60 in cross-brace 58. The alignment may be achieved using a foot operated pedal 63a, 63b provide on bar 63 to slide the hoop into a desired position so that the fastener 59, which is provided on bar 61, may drop into opening 60 to lock the hoop in position. Spring assemblies 61,61 are provided to hold the fastener in opening 60, and to act as a stop mechanism when pressure is applied to either pedal 63a, 63b and the fastener 59 is removed from the opening 60.
Referring again to Figure 3, to allow up and down pivoting of the blade 12 of plow assembly 2, the hoop 14 has a series of three blade mounts 66 provided on bars 68 connected to opposed ends of the hoop 14. The blade mounts 66 have spaced apart and opposed plates 69 with aligned openings 70, so that a fastener such as clevis pin 76 is slidable in the openings 70,74 to lock the blade to the hoop and allow up and down pivoting motion.
A winch 10 powered by the vehicle electrical system is supported by and attached to plate 57 and is connected to loop 23 on extension 22 for raising and lowering the blade.
The blade may be any size or contour according to the work to be done, and has a scraper 77 on its ground engaging lower surface. The blade 12 is pivotally connected to the hoop of the plow assembly to allow the blade to trip forward if it encounters an obstacle during plowing. To return the plow blade back to plowing position a pair of springs 80 are connected between the blade 12 and the hoop 14, symmetrical about the centre line of the blade and hoop. To connect the spring to the blade and the hoop, spring hook 82 on one end of spring 80 fits into the opening in eye bolt 84 fixed to the top of blade 12, and spring hook 82 on opposite end of spring 80 engages the hoop through opening 83 in the side of the hoop. Finally, side markers 88 may be fastened to sides of blade 12 to act as guides.
Referring to Figure 5, in which the vehicle mount assembly 4 is shown in greater detail, the bar 100 supporting spaced mount arms 5 connected thereto has connection brackets 102 fixed to the bar 100 for fixing ` 2125414 _ 8 the entire assembly to the frame of a vehicle. The vehicle mount assembly which as shown is comprised of the bar 100, the mount arms 5 and the brackets 102 may be entirely made of steel, as a single piece or as parts assembled together. To prevent premature wear and aging, the assembly may be coated with a protective finish.
The mount arms 5 are spaced apart a distance selected to cooperate with the receiving arms 30 of the connection assembly. The mount arms may be hollow or solid, and are of a shape to slide into the receiving arms 30. Aligned openings 104 in each mount arm 5 align with openings 36 in each hollow tube receiving arm 30 so that hitch pin 38 may lockingly engage the mount and receiving arms to prevent disengagement during use.
To connect the vehicle mounting assembly to the vehicle frame certain obstacles must be overcome. The brackets are designed to be connected to the body frame of the vehicle at a point where the frame has about 12 inches or more of support along the frame, or as much as is necessary to prevent undesired bending or kinking of the frame. At the same time, the connection must be sufficient to support the mount arms at a height above the ground of about 12 inches, or as high as necessary to engage the receiving arms of the connection assembly and allow for operation or transport of the plow or other device connected to the connection assembly.
For use with the snow plow described herein, the mount arms are preferably 31 inches apart and supported about 12 inches off the ground. When designing the brackets and bar, it is important to ensure that the brackets and bar and any other members do not interfere with springs, steering column, or other vehicle parts.
Accordingly, a single vehicle mounting assembly will not accommodate all vehicles, but these guidelines will assist in determining the shape of the bar and the form and number of brackets and support plates that will be required to provide a vehicle mounting assembly for g connection to a light truck or recreational four-wheel-drive vehicle.
Figure 5 also illustrates the connection of the vehicle mount assembly to a vehicle frame, and is an example of a typical connection. The illustration indicates in particular the connection of the vehicle mount assembly to the frame of a vehicle sold under the trade mark F150, model years 1991 to 1994.
A further example of an embodiment of the connection of the vehicle mount assembly to the frame of a vehicle sold under the trade-mark GMC S-Jimmy, model years 1982-1994, is shown in Figures 6A and 6B. Referring to Figure 6A, the bar 100' supporting spaced mount arms 5 has side walls forming connection brackets 102' for fixing the entire assembly to the vehicle frame. Referring to Figure 6B, the vehicle mount assembly 4 is shown in position for connection to the frame 6 of the vehicle.
In performing the attachment, any tow hooks (not shown) on the vehicle are removed and threaded tow hook supports 180 are inserted through the front of the frame. The mount assembly 4 is loosely attached to the frame by fasteners 182 which join the frame 6, the threaded tow hook supports 180 and bracket 102' via openings 181 and 184. To secure the connection, a support arm 186 has one end fixed to plate 103' on vehicle mount assembly 4 and another end fixed to frame 6, such as by fasteners 188,189. This attachment may be made first on the passenger side of the vehicle and then on the driver side of the vehicle. A U-bolt assembly 190,191 encircles a portion of the frame 6 and bracket 102' to secure the connection. Additionally, flange 102a abuts raised portion 192 on plate 191 of the U-bolt assembly to prevent slippage and to further secure the connection.
It will be seen that vehicle parts or accessories connected to the frame may have to be removed to achieve the connection, and holes (not shown) for receiving fasteners may have to be made in the frame. Also, since 212541~
vehicle frames may differ in configuration of their sides, the angle of the mounting arms 5 may not be horizontal, and shims (not shown) may be required to correct the angle of the mounting arms 5 so they are horizontal for proper reception of the connection assembly 3 for supporting a desired object, such as the plow described herein.
Referring again to Figure 3, the plow is pivotally connected to the connection assembly by pivot pin 50 which engages the A-frame 18. The winch supported on plate 57 is connected to the closed loop 23 on extension 22 of the T-frame 20 of the connection assembly 3 for raising and lowering the blade 12 of the plow. For power the winch is connected to the electrical system of the vehicle, and a remote control (not shown) may be used by the driver of the vehicle.
As shown in Figure 4A, to direct the snow at a particular angle, the blade is angled by moving the sliding hoop 14 along its arc of movement to a desired position where an opening 62 on the sliding hoop 14 is aligned with the central opening 60 in the brace arm 52 connected to the A-frame and a pin 64 is passed through the aligned openings to lock the hoop, and thus the blade, in position. As shown in Figure 4B, if the hands-free spring-loaded fastener assembly is used, thew operator steps on one of pedals 63a,63b and releases the pedal to allow fastener 59 to enter opening 60 to secure the hoop in desired position. The plow is now ready for use, and includes a forward trip mechanism so that if obstacles are encountered during plowing the blade will pivot forward to avoid damage to the plow. Springs 80 are provided to trip the blade back into plowing position once the obstacle is removed.
For ease of mounting and connection of the plow to the vehicle, a dolly may be used. Referring to Figure 7A, an embodiment of a dolly is shown generally at 110.
The dolly acts as a storage stand for the plow or other - 212S~14 object when it is not in use, and is raisable to and lowerable from a mounting height to align the hollow tubes 30 of the connection assembly 3 with the mounting arms 5 on the mounting assembly 4. The dolly has a base 112, two support arms 114,115 and a linkage assembly 116.
The arms 114 and 115 have one end fastened to the base by fasteners 120, and project in substantially a V-shape in a direction away from the base 112. At the other end of each arm 114,115, a caster support 119 is fastened to the arm for attachment of caster wheel 118. The base 112 acts as a support for objects rested on the dolly 110, and the arms have a surface 121 for supporting parts of the supported object, such as a plow blade of a plow.
Base extensions 113 may assist in supporting an object on the base 112.
The linkage assembly 116 has paired parallel link arms 122,124 pivotally connected at one end to the base and at the other end to the caster support 119. The connection to the caster support 119 is effected by pivotally fastening the link arms 122,124 to brackets 126,128 on the caster support 119, using fasteners 130 in aligned openings (not shown) on the brackets and the link arm. The other end of each link arm is pivotally connected to brackets 132, 134 on the base 112 by fasteners 136 in aligned openings (not shown) on the brackets and the link arm. A removable handle 138 has a channel 140 for receiving a connector portion 142 of the linkage assembly 116. By causing one of the link arms to move in an arc toward or away from the base, the linkage assembly will lower or raise the base 112 and any object on the base. The handle 138 may be used to push the dolly or as a lever to lift the parallel links 122,124 and raise and lower the base 112, and thus raise and lower a plow or other object on the dolly.
The position of the base may also be adjusted according to the desired height of the dolly for receiving an object to be supported. The arc through which the link arms may move, the length of the arms 114,115 and link arms 122,124 may be adjusted according to the object to be supported and the desired range of adjustment in height of the base 112.
