Abstract

A self-balancing mounting system for a flat panel display including a first bracket having a first pivot point and a second bracket having a first sliding pivot mechanism with a sliding range of motion located below the first pivot point relative to a vertical axis. The second bracket includes a range of motion between a generally vertical position and a tipped forward position. A minor arm having a first end is pivotally attached to the first pivot point on the first bracket and a second end is pivotally engaged with the first sliding pivot mechanism on the second bracket such that a first force causing the second bracket to tip forward biases the second end of the minor arm upward in the first sliding pivot mechanism. A major arm having a first end is pivotally attached to the minor arm at a location between the first and second ends of the minor arm and a second end is mechanically coupled to the second bracket at a location below the first sliding pivot mechanism such that a second force on major arm biases the second end of the minor arm downward in the first sliding pivot mechanism.

Claims

1. A self-balancing mounting system for a flat panel display comprising:

a first bracket having a first pivot point;

a second bracket having a first sliding pivot mechanism with a sliding range of motion located below the first pivot point relative to a vertical axis, the second bracket comprising a range of motion between a generally vertical position and a tipped forward position;

a minor arm having a first end pivotally attached to the first pivot point on the first bracket and a second end pivotally engaged with the first sliding pivot mechanism on the second bracket such that a first force causing the second bracket to tip forward biases the second end of the minor arm upward in the first sliding pivot mechanism; and

a major arm having a first end pivotally attached to the minor arm at a location between the first and second ends of the minor arm and a second end mechanically coupled to the second bracket at a location below the first sliding pivot mechanism such a second force biases the second end of the minor arm downward in the first sliding pivot mechanism.

2. The system of claim 1 wherein the combination flat panel display and second bracket comprises a virtual pivot point in front of the second bracket on a side opposite the first bracket.

3. The system of claim 1 comprising an equilibrium position where the first and second forces generally offset from each other so that the second bracket remains where positioned with minimal friction.

4. The system of claim 1 comprising an equilibrium position about half way through the range of motion of the second bracket.

5. The system of claim 1 wherein the first force is generally equal to, but in a generally opposite direction from, the second force when the second bracket is about half way through its range of motion.

6. The system of claim 1 wherein the first and second forces on the second bracket comprises gravity.

7. The system of claim 1 wherein the first and second forces on the second bracket comprises gravity acting on the second bracket and the flat panel display.

8. The system of claim 1 wherein the sliding range of motion of the first sliding pivot mechanism limits the range of motion for the second bracket.

9. The system of claim 1 comprising a frictional force between the second end of the minor arm and the first sliding pivot mechanism.

10. The system of claim 1 comprising a frictional force between the second end of the major arm and the second bracket.

11. The system of claim 1 wherein the first sliding pivot mechanism comprises a slot in the second bracket.

12. The system of claim 1 wherein the second end of the major arm comprises:

a pivotal attachment to a second sliding pivot mechanism located on the first bracket at a location below the first sliding pivot mechanism; and

a connecting arm pivotally coupling the second end of the major arm with the second bracket.

13. The system of claim 12 wherein the second sliding pivot mechanism comprises a slot in the first bracket.

14. The system of claim 1 wherein the first bracket comprises a plurality of wall mounting holes.

15. The system of claim 1 wherein the first bracket comprises at least one conduit hole.

16. The system of claim 1 wherein the second bracket comprises a plurality of flat panel display mounting mechanisms.

17. The system of claim 1 wherein the second bracket comprises a flat panel display locking mechanism.

18. The system of claim 1 comprising at least one bottom support for retaining a bottom portion of the second bracket in a fixed spaced relationship relative to the first bracket.

19. An adjustable display system comprising:

a self-balancing mounting system comprising;

a first bracket having a first pivot point mounted to a support structure;

a second bracket having a first sliding pivot mechanism with a sliding range of motion located below the first pivot point relative to a vertical axis, the second bracket comprising a range of motion between a generally vertical position and tipped forward position;

a minor arm having a first end pivotally attached to the first pivot point on the first bracket and a second end pivotally engaged with the first sliding pivot mechanism on the second bracket such that a first force causing the second bracket to tip forward biases the second end of the minor arm upward in the first sliding pivot mechanism; and

a major arm having a first end pivotally attached to the minor arm at a location between the first and second ends of the minor arm and a second end mechanically coupled to the second bracket at a location below the first sliding pivot mechanism such that a second force biases the second end of the minor arm downward in the first sliding pivot mechanism; and

a flat panel display mounted to the second bracket.
