Abstract: This invention relates to a lift to assist persons to stand or walk, where they have insufficient strength in their legs. The lift includes a supporting frame having a front portion extending in front of the person and side portions on each side. There are wheels beneath the supporting frame to enable the lift to be manoeuvered. A lift arm is pivotally mounted on the supporting frame for movement in a vertical plane. A generally U-shaped support member is at the other end of the lift arm and comprises a pair of supporting bars adapted to fit under the armpits of a person. There are means for maintaining the U-shaped support substantially parallel to the ground as the lift arm is raised or lowered and hydraulic means for raising or lowering the lift arm.
