ABSTRACT:
A manually operated uplift apparatus comprising a structural frame unit, a mechanical uplift assembly unit, and a power translating mechanism connecting the two units to allow the user to more easily obtain a standing position from a previously seated position. The structural frame unit is used to support and guide the mechanical uplift assembly unit. The mechanical uplift assembly unit has two sections which can independently move vertically with respect to the structural frame unit. One section has a seat, the other has rails or hand engagement handles. When downward force is applied to the hand engagement handles, the section having the handles move vertically downward and produces an upward force in the section having the seat through the power translating mechanism. This interface allows the user to more easily uplift themselves from a seated position and is especially useful for older and/or medically disabled persons.
