Abstract
Abstract A motor mount, particularly for hospital beds, includes a motor unit equipped with a splined male powered shaft which coacts with a female splined socket which is mounted at a bed motor mounting. The socket is rotatably mounted on a mounting member of the bed frame and is connected to a rotatable part which activates the moving parts of the bed. The splined shaft supports the motor unit which is held against rotation by a slot in a cross frame member and against end play by a spring clip attached to the frame. A plurality of motor units are positioned in a console cabinet in a head or foot board. The console contains operational switches for an attendants use and a master disconnect switch which operates when the cabinet door is completely opened to render safe access to motor servicing and the like. The motor mounting includes a gear housing with an output shaft which is connectable to the female splined socket. The gears in the housing are selectably driven by one of a plurality of different motors or by a hand crank which is connectible to an external crank fitting of the housing.
