[ I claim:] [1.] A lightweight, easily transportable lifting device for assisting a person to rise from a seated position which comprises:(i) a substantially U shaped base support adapted to be disposed upon a supporting surface, having a user receptive front and a spaced apart rear, said base support further comprising:(a) a pair of hollow front legs secured in spaced apart relation by at least one front brace;(b) a pair of hollow rear legs; and(c) a pair of spaced apart horizontal supports each support having a plurality of evenly spaced vertically oriented apertures, each horizontal support mounted between one front and one rear leg;(ii) a pair of spaced apart substantially inverted U shaped handrails, each of said handrails further comprising:(a) a front rail,(b) a rear rail, and(c) a top rail connected between the front rail and rear rail to form the inverted U shape, each of said front rails and said rear rails fabricated with an outside cross sectional diameter smaller than the inside cross sectional diameter of each of the front and rear legs permitting the hand rail to be slidably mounted within said front and rear legs;(iii) an actuator support suspended below each horizontal support, maintained at fixed distance below the top rail by a plurality of support rods;(iv) elevation control means connected between the handrail and actuator support and capable of providing linear motion to the hand rail between a first extended position and a second retracted position relative to the base support; and(v) a motor means connected to the elevation control means providing controlled operation thereof.
