Video monitor

Video display

A support base for a display monitor provides for the rotation and stable orientation of the monitor over a range of tilt angles. An upper portion of the base is adapted to receive a turntable having an upper concave surface adapted to receive a complementary convex lower portion of the display monitor's cabinet. The concave surface of the turntable includes a first pair of spaced guide rails adapted to receive and engage respective complementary guide rail assemblies positioned on the convex lower portion of the monitor. The convex lower portion of the cabinet is further provided with a pair of spaced projections for insertion within respective elongated apertures in the turntable which are parallel to and in spaced relation with its guide rails. Each of these projection assemblies includes engaging means such as the combination of a spring washer and coiled spring for engaging the turntable adjacent to a respective elongated aperture in maintaining the monitor firmly positioned within the turntable's concave surface. A biasing arrangement urges the monitor in a first direction of rotation within the turntable's concave surface which is opposite to the rotational moment of the monitor due to its center of gravity. The lower surface of the turntable is provided with a pair of spaced bosses which are adapted for insertion within and engagement with a respective arcuate slot in the upper surface of the base to provide secured coupling between the base and the turntable and allow for rotational displacement therebetween.

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.
