|20140250738||Quick-Connect Side Wing Plow Hitch - A quick-release attachment system for connecting a wing plow to the side of a vehicle has a mounting block configured to couple to a conventional structure on the wing plow. A mounting block lifting and securing mechanism has a base element affixed to the vehicle and an extendable and retractable slider controlled by a slider actuator. A lift arm is pivotably mounted to the slider and is raised and lowered by a pivot actuator connected between the slider and the lift arm. When lowered, the lift arm can be positioned such that it engages and raises the mounting block when the lift arm is pivoted back to its raised position. The engagement allows the lift arm to carry the mounting block with it when the slider is retracted, drawing the mounting block into a bracket on the base element to which the mounting block can be secured.||09-11-2014|
|20120285050||Quick-Connect Plow Hitch - The front mounting assembly has a vehicle-mounted frame and a plow-mounted frame that are drawn together by a lift actuator such as a hydraulic cylinder, and brought into registry by guides. When the frames are aligned, slides are advanced from one frame into slide receivers affixed to the other frame and secured thereto by pins. The guides include a pair of guide tabs, which protrude from the plow-mounted frame to guidably engage and subsequently cradle a horizontal lower bar on the vehicle-mounted frame, and a pair of angled upper guides on the plow-mounted frame, which engage a pair of vertical plates on the vehicle-mounted frame to help center the plow-mounted frame as it is pulled into position. For plows having a side wing, a rear mounting assembly engages and lifts a mounting block attached to the wing into a base member to which it is pinned.||11-15-2012|
|20100269377||STABILIZED FLOAT MECHANISM FOR MATERIAL-MOVING IMPLEMENT - A float mechanism for movably attaching an implement to a vehicle has a mounting frame that connects onto the vehicle and a fixed frame that affixes to the implement. A pivot bracket pivotally attaches to one of the frames and is slidably connected to the other to accommodate a limited degree of translational motion. The pivot bracket can slidably connect to the frame by a pair of guides in combination with a pair of sleeves. Rotational motion between the fixed frame and the mounting frame can be limited by slots in one of the frames that are slidably engaged by a stabilizing element on the other frame. When the stabilizing element is a horizontal bar, it can engage a pair of vertical slots. To optionally eliminate the free motion between the frames, movable blocks can be employed to limit the motion of each stabilizing element in its slot.||10-28-2010|
