ABSTRACT:
Disclosed is a tilt-swivel base for a CRT display terminal. The base allows the CRT terminal to be readily swiveled around a vertical axis and tilted forward or backward around a horizontal axis or positioned with a combination of both movements. The cradle of the base may be placed within a recess formed in a horizontal supporting surface and thereby confine the base within the recess. By having the recess front-to-back width approximately equal to the front-to-back width of the cradle and the side to side length greater than the side to side width of the cradle, the CRT display terminal and base can be moved from side to side within the recess while still confining it to a fixed front-to-back position. By providing the cradle with a convex front surface and a triangular back surface, the base and CRT display terminal may be swiveled up to the point that one of the two angled back edges of the cradle comes into full contact with the back edge of the recess. The cradle is attached to the rocker drum of the base by means of a shouldered bushing which is attached to the center of the rocker drum by a screw.
