Patent ID: 8042824

Claim:
A wheel mount assembly for mounting a drive wheel to a frame member of a wheelchair frame, the wheel mount assembly comprising: a clamp assembly comprising left and right fasteners and a clamping member arranged to be coupled to the wheelchair frame at a fixed angle about the frame member; left and right camber bodies, each camber body attachable to an axle of a respective one of the drive wheels and each operable to pivotably couple said one of the drive wheels about a respective frame member of the wheelchair frame through a range of camber angles; and left and right spacers, each spacer operable to be clamped between the clamping member and a respective one of the camber bodies so as to set a desired camber angle of the camber body; each spacer comprising a set screw which is screwed into one of the respective camber body or the clamp member such that the spacer is adjustable relative to the camber body between a plurality of different positions wherein each of the different positions is a different distance that the set screw is screwed into said one of the respective camber body or the clamp member which corresponds to a different camber angle; the clamp member of said clamp assembly comprising a transverse member extendable between the drive wheels and having two ends, each end operable to engage a portion of the wheelchair frame such that the clamp member is prevented from pivoting through the camber angles of each respective camber body; the left and right fasteners of said clamp assembly being operable to secure respective ones of the camber bodies relative to the clamping member such that the respective spacers are each clamped between the respective camber body and the clamping member at a selected one of the different positions of the spacer and the respective camber body is fixed at a corresponding one of the different camber angles.
