Abstract

A self-balanced adjustable mounting system for a flat panel display. A display interface having a hollow, semi-spherical shell portion is attached to the flat panel display. The semi-spherical shell is formed with a generally constant radius of curvature. The center of the radius of curvature is disposed proximate the center of gravity of the flat panel display with the display interface attached. The display interface is received in a guide structure that has a bearing portion engaging the outer surface of the semi-spherical shell, and a second bearing portion engaging the inner surface of the semi-spherical shell through an aperture formed in the semi-spherical shell. The semi-spherical shell is guided between the first and second bearing portions so that the flat panel display and device interface are generally rotatable about the center of the radius of curvature of the semi-spherical shell. The display is self balancing in virtually any position in the range of travel of the device due to the location of the center of rotation proximate the center of gravity.

Claims

1. A method of adjustably mounting a flat panel display to a fixed structure comprising steps of:

attaching a device interface portion, including a frusto-spherical shell with a flange portion, to the flat panel display, the flange portion extending radially outwardly from the frusto-spherical portion, the flange portion further including structure for receiving at least one fastener to attach the device interface portion to the flat panel display, the flat panel display having a center of gravity, the shell having an outwardly facing convex outer surface with a generally constant radius of curvature and an inner surface, said radius of curvature having a center proximate the center of gravity;

operably coupling the device interface portion to a guide portion, said guide portion having a first bearing portion engaging and guiding the outer surface of the frusto-spherical shell and a second bearing portion engaging and guiding the inner surface of the frusto-spherical shell, the flat panel display being rotatable about a multiplicity of axes oriented generally parallel to the flange and extending through the center of said radius of curvature; and

coupling the guide portion to the fixed structure.

2. The method of claim 1, further comprising a step of positioning the flat panel display by rotating the flat panel display about the center of the radius of curvature of the frusto-spherical shell.

3. The method of claim 2, wherein the step of positioning includes rotating the flat panel display about an axis extending horizontally through the center of the radius of curvature of the frusto-spherical shell.

4. The method of claim 2, wherein the step of positioning includes rotating the flat panel display about an axis extending vertically through the center of the radius of curvature of the frusto-spherical shell.

5. The method of claim 1, including molding the bearing portion from a high modulus thermoplastic.
