Abstract
An invalid hoist comprises a base having a column support socket, an upstanding column detachably mounted in said socket and a lifting arm extending from the column. Said arm is movable along the column by a screw-and-nut lifting mechanism within the column, with the nut of said mechanism being coupled to the arm. A reversible electric motor unit and battery for energization of the motor are mounted on said base with an output shaft of a reduction gear box of the motor unit aligned with and directly coupled to the lower end of the screw of said lifting mechanism to provide a drive from the motor to the screw, through the socket. The drive between said output shaft and said screw is provided by a coupling which can readily be broken to enable the column to be detached from the base without disturbing the motor.
