US Patent 7506388 Invalid lift apparatus

The invalid lift apparatus provides a compact and portable device for lifting, supporting, and lowering an invalid. The invalid is lifted in a substantially single vertical plane, with a curved cushioned lift under each arm. Straps and harness safely and selectively secure the individual to the lifts. The screw jack provides exact height positioning of the invalid. The base deck cutout allows the invalid to access toileting and other needs. The carpet rollers and larger diameter pivotal wheels provide excellent maneuverability. The width no greater than 20 inches and length no greater than 30 inches provides apparatus access throughout a home, even through narrow doorways.
