Abstract

Aspects of the present invention provide a display support arm assembly that includes a proximal housing supporting at least one proximal shaft, a distal housing spaced from the proximal housing and supporting at least one distal shaft, and at least one link extending from the at least one proximal shaft to the at least one distal shaft. The at least one link is coupled for pivotal movement about an axis of the at least one proximal shaft. The display support assembly also includes a gas strut extending between the proximal housing and the distal housing. The gas strut provides substantially constant force throughout a range of the vertical adjustment of the display support arm. The display support assembly further includes at least one torque element associated with either or both of the at least one proximal shaft and the at least one distal shaft. The at least one torque element providing force throughout the range of the vertical adjustment of the display support arm, wherein the force is adjustable by adding or subtracting the number of the at least one torque element.

First claim

What is claimed is:

1. A display support arm assembly configured for vertical adjustment, the display support arm comprising:
a proximal housing supporting at least one proximal shaft;
a distal housing spaced from the proximal housing;
at least one link extending from the proximal housing, the at least one link being coupled for pivotal movement relative to the proximal housing, the at least one link having a knob; and
a gas strut extending between the proximal housing and the distal housing, the gas strut being coupled at a distal end to the knob and coupled at a proximal end to an adaptor, and
wherein the gas strut provides a force throughout a range of the vertical adjustment of the display support arm; and
wherein the adaptor is mounted for linear adjustability to adjust the force provided by the gas strut.

2. The display support arm assembly of claim 1 , further comprising a shell coupling the adjustment rod to the distal housing, the shell retaining the adjustment rod with respect to the distal housing, wherein the shell is formed of a material that is dissimilar to a material of the distal housing.

3. The display support arm assembly of claim 2 , wherein the material of the shell is more flexible than the material of the distal housing.

4. The display support arm assembly of claim 3 , wherein the shell is formed of a polymer material.

5. The display support arm assembly of claim 4 , wherein the distal housing is formed of a metallic material.

6. The display support arm assembly of claim 2 , wherein the shell is disposed within a cavity in the distal housing.

7. The display support arm assembly of claim 6 , wherein the shell is secured within the cavity by press fitting the shell at least partially within the cavity.

8. The display support arm assembly of claim 6 , wherein the adjustment rod does not contact the distal housing.

9. The display support arm assembly of claim 8 , wherein the distal housing defines an opening providing access to the adjustment rod, and the shell defines an opening providing access to the adjustment rod that aligns with the opening of the distal housing.
