Tiltable rotating display monitor mount

Claim 1

A tiltable rotating assembly for a display monitor having a convex lower portion with a first aperture therein for stably positioning said display monitor over a continuum of tilt and rotational orientation angles, said assembly comprising: a base having a generally flat, circular upper recessed portion including a pair of facing arcuate slots therein and a second aperture positioned therebetween and generally in the center of said upper recessed portion; a generally circular housing adapted for insertion within the upper recessed portion of said base and including first coupling means positioned within said arcuate slots for coupling said housing to said base and for permitting rotational displacement therebetween, said housing further including an upper concave portion adapted to receive the convex lower portion of the display monitor and having a pair of elongated, spaced slots and a third aperture positioned therebetween and generally in the center of the upper concave portion of said circular housing, wherein said first, second and third apertures are aligned with one another; second coupling means including first and second connecting members mounted in spaced relation to the convex lower portion of the display monitor and inserted through a respective elongated slot in the upper concave portion of said housing in combination with a respective combination of a coil spring and a bushing positioned in contact with said housing for coupling said display monitor to said housing and for permitting the displacement of the display monitor over a continuum of tilt angles, wherein the engagement between said display monitor and said housing may be varied by adjusting the force exerted upon said bushing by said coil spring and wherein the center of gravity of said display monitor exerts a rotational moment urging said display monitor in a first direction of rotation within said housing; first and second pairs of complementary, mutually engaging guide rails respectively positioned on the convex lower portion of the display monitor and on the upper concave portion of said housing, wherein each of said second pair of guide rails is parallel to and closely spaced from a respective elongated slot in the upper concave portion of said housing; and biasing means positioned within said aligned first, second and third apertures and coupling said display monitor and said base for urging said display monitor in a second, opposite direction of rotation within said housing in counterbalancing the rotational moment of said display monitor's center of gravity in providing for the stable positioning of said display monitor over a continuum of tilt angles.
