Patent ID: 8393096

Claim:
A combination of a motorized wheelchair and plow assembly movable across a surface by the driving action of wheelchair power wheels against the surface, comprising: a wheelchair having: power wheels; first and second tip wheels, in front of the power wheels, rotatably mounted an elevation distance above the surface wherein said tip wheels do not engage the surface when the wheelchair is moving across the surface; and a plow assembly comprising: a blade for pushing snow or debris toward a side of the wheelchair; a handle operatively connected to the blade; first and second wheel push brackets disposed at a back side of the blade at approximately the elevation distance above the surface, each push bracket contactable against a respective one of the first and second tip wheels, wherein when the push brackets are in contact with the tip wheels, movement of the wheelchair is imparted to the plow assembly by the tip wheels via the push brackets; and first and second blade wheels contactable with the surface and rotatably mounted proximate to outer bottom corners of the blade; wherein while the wheel push brackets are in pressed contact with the tip wheels the power wheels remain against the surface, and the blade may be rotated, by a force applied to the handle, to lift a bottom edge of the blade from the surface by pivoting the push brackets and tip wheels around axes of the tip wheels.
