Display unit lifter

Abstract

A lifter particularly usable for an LC display unit includes a slide board bearing the display unit overhead and driven for vertical movement by a lift drive motor associated with a swing arm kept in rolling contact with the slide board, a gear assembly mounted to the slide board for converting rotation of a tilt drive motor into corresponding tilting of the display unit, and various sensors for controlling rotation of the motors on detection of the positions of the display unit. Vertical movement of the display unit requires a quarter rotation of the swing arm which is very small in ambit and, as a consequence, a compact and light design of the entire lifter construction. The rolling contact of the swing arm with the slide board assures reliable fail-safe function when smooth vertical movement of the slide board is hindered by accidental introduction of a foreign matter in its path of travel.
