Abstract
A snow plow and mount assembly has a mount frame, an A-frame, a lift frame, a plow blade, an actuator, arms, receivers, recesses, hitch pins, a latch mechanism, and a latch lever. The elements are arranged such that the vehicle is driven toward the snow plow so that the arms are received in the receivers, the actuator is energized to pivot the lift frame relative to the A-frame so that the hitch pins are received in the recesses, and the lever is moved to move the latch mechanism to the latched position. The snow plow frame is thereby removably secured to the mount frame.
Claims16
1-41. (canceled)
A snow plow and mount assembly comprising:
- a mount frame adapted to be secured to a vehicle,
- a snow plow frame having an A-frame and a lift frame pivotally connected relative to one another for pivoting movement about a generally transverse horizontal axis,
- a plow blade pivotally connected relative to said A-frame for pivoting movement about a generally vertical axis,
- an actuator operably associated with said A-frame and said lift frame for imparting relative pivoting movement between said A-frame and said lift frame,
- one of said mount frame and said lift frame having first and second arms and the other of said mount frame and said lift frame having first and second receivers, said first and second arms received in respective ones of said first and second receivers upon relative movement therebetween toward one another,
- a trunnion, said trunnion and A-frame pivotally connected to one another for pivoting movement about a generally longitudinal horizontal axis, said lift frame and said trunnion pivotally connected to one another for pivoting movement about the generally transverse horizontal axis, and
- a resilient member operably associated with said pivotal connection of said trunnion and said A-frame to impart a degree of stiffness to said pivotal connection.
52-56. (canceled)
A snow plow and mount assembly comprising:
- a mount frame adapted to be secured to a vehicle,
- a snow plow frame having an A-frame and a lift frame pivotally connected relative to one another for pivoting movement about a generally transverse horizontal axis,
- a plow blade pivotally connected relative to said A-frame for pivoting movement about a generally vertical axis,
- an actuator operably associated with said A-frame and said lift frame for imparting relative pivoting movement between said A-frame and said lift frame,
- one of said mount frame and said lift frame having at least a first arm and the other of said mount frame and said lift frame having at least a first receiver, said arm received in said receiver upon relative movement therebetween toward one another,
- a trunnion, said trunnion and A-frame pivotally connected to one another for pivoting movement about a generally longitudinal horizontal axis, said lift frame and said trunnion pivotally connected to one another for pivoting movement about the generally transverse horizontal axis, and
- a resilient member operably associated with said pivotal connection of said trunnion and said A-frame to impart a degree of stiffness to said pivotal connection.
The assembly of claim 17 further comprising:
- said support stand biased toward the retracted position, and
- a cam actuating pin movably connected to said lift frame for translational movement between a deployed position and a stowed position,
- said cam actuating pin operably associated with a cam surface of said stand and said lever operably associated with said cam actuating pin such that, when said lever is moved to move said latch pins to the unlatched position said cam actuating pin moves to the deployed position, and when said actuator is energized to pivot said lift frame relative to said A-frame in the second direction said cam actuating pin contacts said cam surface of said stand whereupon further pivoting of said lift frame relative to said A-frame in the second direction moves said support stand to the deployed position, and when said actuator is energized to pivot said lift frame relative to said A-frame in the first direction said support stand returns to the retracted position, and when said lever is moved to move said latch pins to the latched position said cam actuating pin moves to the stowed position.
