Tilt swivel base
First Claim
1. A terminal base of the type having a transverse centerline and comprisingA. a hollow box-like lower section having a front, a back and a pair of opposite sides;
- B. swivel means mounted to the underside of said lower section permitting said section to swivel relative to a support surface on which they rest;
C. a hollow box-like upper section(1) having a front, a back and a pair of opposite sides;
(2) positioned on the lower section; and
(3) having terminal-supporting top surface means;
D. said upper and lower sections having opposing mating surface portion which are curved from front to back more or less about an imaginary axis which(1) is substantially parallel to the transverse center line of said base; and
(2) lies appreciably above the confines of the base so that, when the upper section is moved on the lower section in either direction about said axis, the upper section is tilted relative to the lower section;
E. means for limiting the movement of the upper section on the lower section in said directions; and
F. coacting means on said upper and lower sections defining selected positions of adjustment in the movement of the upper section relative to the lower section.

Abstract
A tilt swivel base for a video terminal includes a lower section which is supported by way of a swivel so that the lower section can be swiveled relative to a supporting surface. An upper section is supported on the lower section, the two sections mating at surfaces which are curved from the front to the back of the base about an imaginery axis which is located appreciably above the base. The upper section is movable relative to the lower section forwardly and rearwardly so as to adjust the tilt angle of the upper section and of a terminal supported thereby relative to the supporting surface. Structures for controlling the relative motion of the upper and lower sections as well as establishing their relative positions are also disclosed.

17. A terminal base of the type having a transverse centerline and comprising
A. a lower section, said lower section including a top wall curved about an imaginary axis which extends parallel to the transverse centerline of the base and lies an appreciable distance above the base; -
B. an upper section, said upper section (1) including a bottom wall having the same curvature as said lower section top wall, and (2) being positioned on the lower section with said curved walls in opposition; C. track-defining means extending along one of said curved walls substantially perpendicular to said centerline; D. a plurality of wheels rotatively supported at the other curved wall in engagement with said track-defining means so that the upper section is constrained to roll relative to said lower section about said axis whereby the upper section tilts relative to the lower section; E. means for limiting the rolling excursions of the upper section; and F. means for restraining rolling movements of the upper section at selected positions along said track-defining means so as to releasably set the upper section at selected tilt angles. - View Dependent Claims (18, 19, 20, 21, 22, 23)
