Abstract
In a CRT display device system, an upper assembly, including the display device, is tiltable on a supporting base assembly. A gear segment at each end of the upper assembly rests on a pair of pinions on the base assembly. The radius of curvature of each gear segment is centered on a horizontal line passing across the display device and through or near the center of gravity of the upper assembly. As the upper assembly is tilted, it pivots about this line and therefore remains substantially in balance for all angles of tilt. To provide static rest pressure to prevent unwanted tilting movement and also to minimize backlash, the pinions in each pair are coupled together through an idler pinion.
