Abstract
A video monitor suspension system including a four bar linkage arm for adjustable and positionable vertical and horizontal support of a video monitor, computer, computer keyboard, or a like structure. A weight counterbalance sliding anchor mechanism assembly adjustably compensates for various weights of a load held by an angled arm. Gas springs provide for vertical support of a four bar linkage arm. Reinforcement channels in the four bar linkage arm members provide for increased torsional rigidity of the video monitor suspension system and allow for the incorporation of lighter weight linkage arm members. A large pivot bearing assembly also provides for stability when used with an input device, such as a keyboard. Additional structure provides for the safety of the computer suspension system operator.
