Patent number: 11555282Abstract: A snow plow and mount frame assembly permits an operator to attach and detach a snow plow to and from a mount frame secured to a vehicle, without the operator exiting a cab of the vehicle. The assembly comprises a mount frame, a snow plow frame, a plow blade, a first actuator for pivoting the A-frame relative to the lift frame, a latch mechanism, and a second actuator to either latch or unlatch the latch mechanism. When the vehicle is driven toward the snow plow the snow plow frame mates with the mount frame and an electrical connection is made between the vehicle electrical system and at least the first actuator without manual manipulation. The second actuator is energized to either latch the latch mechanism thereby securing the snow plow frame to the mount frame or unlatch the latch mechanism thereby freeing the snow plow frame from the mount frame.Type: GrantFiled: December 6, 2019Date of Patent: January 17, 2023Assignee: Douglas Dynamics, LLCInventors: Chad Thomas Barker, David N.

Patent number: 11427978Abstract: 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.Type: GrantFiled: August 10, 2020Date of Patent: August 30, 2022Assignee: Douglas Dynamics, L.L.C.Inventors: Chad Thomas Barker, David N.

Patent number: 8850724Abstract: A plow assembly for attachment to a vehicle having a longitudinal axis comprises a plow blade having first and second ends, a first plow wing pivotally mounted to the first end of the plow blade, and a plow support adapted to be operably mounted to the vehicle. The first plow wing is biased by a first compression. A first connecting member is connected to the first plow wing, passes through the first compression spring generally coaxially therewith, and is connected to the plow support. The first connecting member is configured to pivot the first plow wing relative to the plow blade during pivoting of the plow blade from a center position to a first position such that when the plow blade is in the first position the first plow wing is generally parallel to the plow blade.Type: GrantFiled: February 15, 2013Date of Patent: October 7, 2014Assignee: Douglas Dynamics, L.L.C.Inventor: David N.
