  • Patent number: 4674601
    Abstract: Apparatus for enabling wheelchair-confined individuals to more easily convey themselves between two different elevations, especially between the inside ground level of a house and the outside ground level. The key to the invention is a unitary molded lift or scoop on which the wheelchair rides while being conveyed between the two levels. This lift is formed so as to maintain the wheelchar seat in a horizontal orientation during transit. The lift is mounted in a frame in which also resides the peripheral equipment needed to raise and lower the lift. The lower end of the lift is attached to a pair of cables which pass up to and through the top of the frame and then around the take-up reels. The opposite end of the lift is attached by a hinge to the frame at the level of the higher elevation. In its preferred embodiment, the lift conveys the wheelchair between the interior of the ground floor of a house and the ground level outside.
