ABSTRACT:
A tilt/swivel display base for a product such as video display terminals and similar devices. The base contains few moving parts and results in only a limited displacement above the work surface. The display base has one or more rocker legs which have arcuate cross sections. The rocker legs allow forward and backward tilting of the video display terminal. Locking wedges are provided to stabilize the display base in a selected position. Swiveling is accomplished by rotating the entire video display terminal and display base about a vertical axis. Rotation about a vertical axis is possible due to the small area of contact between the display base rocker legs and the work surface. The locking wedges are maintained in position by locking wedge flanges with mate with a groove in the rocker leg. A tensioning device is provided to insure constant pressure between the locking wedge and the rocker leg. A stop can be incorporated on the rocker legs to prevent excessive tilting.
