Abstract
A monitor arm includes a mounting assembly adapted to be coupled to a support structure and a parallelogram mechanism coupled to the mounting assembly. The parallelogram mechanism includes a support member adapted to couple to an object, such as a computer monitor, a first arm pivotably coupled to the mounting assembly at a first pivot axis and pivotably coupled to the support member at a second pivot axis, and a second arm pivotably coupled to the mounting assembly at a fifth pivot axis and pivotably coupled to the support member at a fourth pivot axis. The monitor arm includes a counterbalancer having a first end coupled to the mounting assembly at a third pivot axis and a second end coupled to the first arm at the second pivot axis. The third pivot axis is vertically above and vertically aligned with the first and fifth pivot axes. The mounting assembly includes an adjustment mechanism for adjusting the position of the third pivot axis relative to the first and fifth pivot axes to adjust a counterbalancing force exerted on the parallelogram mechanism by the counterbalancer.
