Abstract

A support apparatus includes an arm assembly attached to a support assembly such that the arm assembly is positionable adjacent to an article of furniture such as a desk or work surface. A mounting device is attached to the arm assembly that is sized and configured to retain a display device. A vertically adjustable attachment mechanism attaches a first end of the counterbalance mechanism to the arm assembly or support assembly. The vertically adjustable attachment mechanism is sized and configured such that a vertical position of the first end of the counterbalance mechanism is adjustable via movement of at least one component of the vertically adjustable attachment mechanism.

First claim

What is claimed is:

1. A support apparatus comprising:
an arm assembly, the arm assembly having a first end and a second end;
a support assembly attached to the arm assembly;
a mounting device attached to the arm assembly, the mounting device sized to retain a display device;
a counterbalance mechanism extending between the first end of the arm assembly and the second end of the arm assembly, the counterbalance mechanism having a first end and a second end opposite the first end;
a vertically adjustable attachment mechanism attaching the first end of the counterbalance mechanism to one of: the arm assembly and the support assembly, the vertically adjustable attachment mechanism sized and shaped such that a vertical position of the first end of the counterbalance mechanism is adjustable, the vertically adjustable attachment mechanism comprising
a receiving body immovably affixed to the first end of the arm assembly or the support assembly, the receiving body having a groove,
a rotatable member that is attached to the receiving body, the rotatable member being rotatable in a first direction and in an opposite second direction,
a nut or moveable body attached to or positioned on the first end of the counterbalance mechanism, the nut or moveable body also being moveably attached to the rotatable member such that rotation of the rotatable member causes the nut or moveable body to move along the rotatable member to change a vertical position of the first end of the counterbalance mechanism, rotation of the rotatable member in the first direction driving movement of the nut or moveable body to change the vertical position of the first end of the counterbalance mechanism to a higher location and rotation of the rotatable member in a second direction driving movement of the nut or moveable body to change the vertical position of the first end of the counterbalance mechanism to a lower position, and
the nut or moveable body having a projection positioned within the groove of the receiving body such that the projection is mateable within the groove and prevents rotation of the nut or moveable body as the nut or moveable body is vertically moved along the rotatable member when the rotatable member rotates.

2. The support apparatus of claim 1 wherein the first end of the counterbalance mechanism has a hole that is sized to receive the rotatable member and the first end of the counterbalance mechanism is positioned on the nut or moveable body such that vertical movement of the nut or moveable body causes the first end to move vertically.

3. The support apparatus of claim 1 wherein the rotatable member is a bolt or a screw that has a length, the length extending substantially vertically.

4. The support apparatus of claim 1 wherein the receiving body is immovably affixed to the first end of the arm assembly such that the receiving body does not move independent of the first end of the arm assembly.

5. The support apparatus of claim 1 wherein the mounting device is sized and configured to releasably retain a mechanical tool and wherein the mechanical tool is engageable with a portion of the rotatable member while rotating to cause the rotatable member to rotate to adjust a vertical position of the first end of the counterbalance mechanism.

6. The support apparatus of claim 1 wherein the counterbalance mechanism is a gas spring.

7. The support apparatus of claim 1 wherein the arm assembly is comprised of a first arm positioned between the first end and the second end of the arm assembly, the vertically adjustable attachment mechanism being attached to the first arm for directly attaching the first end of the counterbalance mechanism to the first end of the arm assembly, the counterbalance mechanism extending from the first end of the arm assembly to adjacent the second end of the arm assembly; and
wherein the nut or moveable body does not rotate and moves linearly along the rotatable member when the rotatable member rotates.

8. The support apparatus of claim 1 further comprising a mounting mechanism attached to the support assembly, the mounting mechanism being comprised of a clamp and wherein the mounting device comprises a mounting plate sized and configured for attachment to the display device.

9. The support apparatus of claim 8 wherein the counterbalance mechanism is a gas spring.

10. The support apparatus of claim 8 wherein the arm assembly is comprised of a first arm member positioned between the first end and the second end of the arm assembly, the vertically adjustable attachment mechanism being attached to an end of the first arm member for directly attaching the first end of the counterbalance mechanism to the arm assembly and wherein the mounting device is attached to the second end of the arm assembly.

11. The support apparatus of claim 8 wherein the arm assembly is comprised of at least one arm member.

12. The support apparatus of claim 8 wherein the rotatable member is a bolt or screw.

13. The support apparatus of claim 8 wherein the arm assembly is comprised of a first arm positioned between the first end and the second end of the arm assembly, the vertically adjustable attachment mechanism being attached to the first arm for directly attaching the first end of the counterbalance mechanism to the first end of the arm assembly, the counterbalance mechanism extending from the first end of the arm assembly to adjacent the second end of the arm assembly.

14. The support apparatus of claim 8 further comprising a mechanical tool and wherein the mounting device releasably retains the mechanical tool and wherein the mechanical tool is engageable with the rotatable member while rotating to rotate the rotatable member to adjust a vertical position of the first end of the counterbalance mechanism.
