ABSTRACT:
For use with a display unit for a word processing system, apparatus is provided for support of the display unit to allow the operator to easily and quickly change the tilt angle of the display unit and retain the tilt angle after a change thereof. The support and rocking tilt apparatus is mounted to the base of the display unit and includes fore/aft retention by a spur gear form on the upper support unit and a rack gear form on the lower support unit, which co-locates the origin of the arc of the rocker, the center of gravity and the origin of the arc of the pitch diameter of the spur gear of the display unit through the tilt range. Rocker means associated with the gear forms provides side-to-side retention of the support and rocking tilt apparatus. Vertical retention apparatus is combined with a snubbing device, including a spring-loaded friction mechanism, which provides infinite actuation throughout the tilt range.
