Abstract
An invalid lifting device includes a mobile chassis, a lifting mechanism and a sling connectible to the arm supports to assist in raising a seated person to a standing or substantially standing position. The lifting mechanism includes a lifting arm and an actuator device operative to raise and lower the lifting arm. The lifting arm is pivotable about first and second horizontal axes, the first horizontal axis being fixed and being further from the arm supports than the second horizontal axis. The lifting mechanism also includes guiding elements defining a guide path along which the second horizontal axis is caused to move as the actuating device raises and lowers the lifting arm.
