  • Patent number: 11555282
    Abstract: 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.

  • Patent number: 11427978
    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.

  • Patent number: 11284702
    Abstract: A robot cleaner including a body, a driven wheel, and a side brush coupled to the body. The side brush includes a hub configured to rotate about a pivot axis and a plurality of bristles. Some bristles may form a first angle with the pivot axis and others form a second angle with the pivot axis which is larger than the first angle. Some bristles may have a first bristle length and others have a second bristle length which is larger than the first bristle length. The robot cleaner may include a side brush deflector to deflect debris propelled by the side brush towards the vacuum inlet. The side brush deflector includes a plurality of deflector bristles extending downwardly from a floor facing surface of the robot cleaner towards a floor such that some of the bristles pass through or underneath a portion of the deflector bristles.
