Abstract

The invention includes a display positioning assembly including a pivot mechanism adapted to accommodate a range of display weights.

First claim

What is claimed is:

1. A pivot mechanism for adjusting a position of an electronic display, the pivot mechanism comprising:
a first structural member including a first planar member extending between two side members;
a second structural member including:
a first side;
a second side parallel to the first side; and
a third side extending between the first and second sides, the third side including a second planar member,

wherein the first structural member is pivotally attached to the second structural member about a tilt axis, wherein the first structural member is coupled to an electronic display mounting bracket;
at least one torsion spring positioned about the tilt axis and having a first leg and a second leg, the first leg engaging the first structural member;
an adjustment plate engaging the second leg of the torsion spring,ustment plate configured to adjust a position of the second leg; and
a tilt adjust screw having a longitudinal axis extending parallel to the third side of the second structural member, the tilt adjust screw extending through the adjustment plate, the tilt adjust screw moveably coupling the adjustment plate to the second structural member along an axis generally perpendicular to the tilt axis.

2. The pivot mechanism of claim 1 , wherein the first structural member is pivotally attached to the second structural member by at least one bolt extending along the tilt axis.

3. The pivot mechanism of claim 1 , wherein the second structural member defines a threaded hole to receive the tilt adjust screw.

4. The pivot mechanism of claim 1 , wherein the mounting bracket is pivotally connected to the first structural member.

5. The pivot mechanism of claim 1 , wherein there are a plurality of torsion springs, each with a first leg engaging the first structural member and a second leg engaging the adjustment plate.

6. The pivot mechanism of claim 1 , wherein the first leg engages a notch defined by the first structural member.

7. The pivot mechanism of claim 1 , wherein the second structural member is connected to a display positioning assembly.

8. A pivot mechanism for adjusting a position of an electronic display, the pivot mechanism comprising:
a first structural member including a first planar member extending between two side members;
a second structural member including:
a first side;
a second side parallel to the first side; and
a third side extending between the first and second sides, the third side including a second planar member,

wherein the first structural member is pivotally attached to the second structural member about a tilt axis, wherein the first structural member is coupled to an electronic display mounting bracket;
at least one torsion spring positioned about the tilt axis and having a first leg and a second leg, the first leg engaging the first structural member; and
a tilt adjust screw having a longitudinal axis extending parallel to the third side of the second structural member, the tilt adjust screw positioned generally perpendicular to the tilt axis and moveably coupled to the second structural member, wherein the second structural member defines a threaded hole to receive the tilt adjust screw and an adjustment of the tilt adjust screw adjusts a position of the second leg of the torsion spring.

9. The pivot mechanism of claim 8 , wherein the first structural member is pivotally attached to the second structural member by at least one bolt extending along the tilt axis.

10. The pivot mechanism of claim 8 , wherein the mounting bracket is pivotally connected to the first structural member.

11. The pivot mechanism of claim 8 , further including an adjustment plate coupled to the tilt adjust screw and moveable with respect to the second structural member along an axis generally perpendicular to the tilt axis, the adjustment plate engaging the second leg of the torsion spring.

12. The pivot mechanism of claim 8 , wherein the first leg engages a notch defined by the first structural member.

13. The pivot mechanism of claim 8 , wherein the second structural member is connected to a display positioning assembly.

14. A pivot mechanism for adjusting a position of an electronic display, the pivot mechanism comprising:
a first structural member including a first planar member extending between two side members;
a second structural member including:
a first side;
a second side parallel to the first side; and
a third side extending between the first and second sides, the third side including a second planar member,

wherein the first structural member is pivotally attached to the second structural member about a tilt axis, wherein the first structural member is coupled to an electronic display mounting bracket;
at least one torsion spring positioned about the tilt axis and having a first leg and a second leg each extending away from the tilt axis, the first leg engaging the first structural member; and
a tilt adjust member having a longitudinal axis extending parallel to the third side of the second structural member, the tilt adjust member positioned generally perpendicular to the tilt axis, wherein an adjustment of the tilt adjust member adjusts a position of the second leg of the torsion spring.

15. The pivot mechanism of claim 14 , wherein the first structural member is pivotally attached to the second structural member by at least one bolt extending along the tilt axis.

16. The pivot mechanism of claim 14 , wherein the tilt adjust member is moveably coupled to the second support member.

17. The pivot mechanism of claim 16 , wherein the second structural member defines a threaded hole to receive the tilt adjust member.

18. The pivot mechanism of claim 16 , further including an adjustment plate coupled to the tilt adjust member and moveable with respect to the second structural member along an axis generally perpendicular to the tilt axis, the adjustment plate engaging the second leg of the torsion spring.

19. The pivot mechanism of claim 14 , wherein the mounting bracket is pivotally connected to the first structural member.

20. The pivot mechanism of claim 14 , wherein the first leg engages a notch defined by the first structural member.

21. The pivot mechanism of claim 14 , wherein the second structural member is connected to a display positioning assembly.

22. The pivot mechanism of claim 1 , wherein the first side of the second structural member is configured to engage a first rail of a first slide, and wherein the second side of the second structural member is configured to engage a second rail of a second slide.
