ABSTRACT:
An invalid lifting device is disclosed. A mast is mounted to a frame to rotate about a vertical axis. A boom is mounted to the mast to swing with the mast and to pivot about a horizontal axis. A sling for supporting an invalid extends from the end of the boom. A first motor drives the mast to rotate and a second motor is mechanically linked with an extendible strut to raise and lower the boom. A control box is provided in the proximity of an invalid as he is seated in the sling to allow the user to select an elevational and rotational movement. A computer controls movement of the device based upon input at the control box.
