Tiltable display monitor assembly

摘要

A support base for a display monitor provides for the stable orientation of the monitor over a range of tilt angles. An upper portion of the base includes a concave surface adapted to receive a complementary convex lower portion of the display monitor's cabinet. The concave surface of the base includes a pair of spaced, upraised, parallel, elongated, lateral guide rails adapted to receive and engage respective guide rail assemblies positioned on the convex lower portion of the monitor. The convex lower portion of the cabinet is further provided with a center projection for insertion within an elongated center aperture in the concave support surface positioned between the paired guide rails. The center projection is coupled to the base by means of a stretchable element such as an extension spring for applying a moment to the monitor tending to rotate it in a first direction within the concave surface. The biasing spring is coupled to the monitor such that the first direction of rotation is opposite to the rotational moment of the monitor due to its center of gravity. The monitor is thus maintained, once oriented as desired, at a stable tilt angle by these opposing moments. Each of the guide assemblies positioned on the cabinet's lower convex surface includes engaging means such as the combination of a spring washer and tension clip for engaging a respective guide rail in maintaining the monitor firmly positioned within the base's concave surface.
