Abstract: The present invention is a wheelchair scale adapter comprising a substantially planar platform defining a cut out near a center and side walls and a rear wall respectively projecting upwardly therefrom, and having legs adjustably attached thereto for providing added stability, particularly when loading and unloading a wheelchair from the platform; an access ramp hingedly connected to the front of the platform for allowing a wheelchair-bound person to be wheeled onto the platform; a typical bathroom scale, etc., attached to the lower surface of the platform; the invention being adapted for weighing a wheelchair and an occupant which has been wheeled onto the platform. The invention also comprises a ramp mounted on the platform, and associated linkage, for causing the access ramp to rotate upwardly out of contact with a surface on which the invention rests, so as to give a more accurate reading of the weight of a person and wheelchair on the platform.
