Abstract: An assisting lifting, standing and walking device employs base side members whose rear track width is adjustable to facilitate use of the device to lift severly disabled, elderly or other physically challenged persons from a wheelchair, and then allow the overall device width to be reduced for passage through narrow doorways or other passageways. The device also employs a lifting mechanism which can be adjusted by means of a hydraulic jack over a wide range of positions to facilitate lifting of individuals from a prone position on the floor to a standing position. The lifting mechanism includes a pair of individually adjustable generally L-shaped lifting yoke arms that can be adjusted both vertically and angularly to accommodate individuals with posture conditions and provide selective weight bearing alleviation. A special full body harness is employed with the device which has long thigh wraps and a wide lumbar belt for widely distributing lifting pressure and reducing the risk of injury.
