  • Patent number: 5876008
    Abstract: A suspension system having a four bar linkage system including an angled arm for adjustable and positionable vertical and horizontal support of a video monitor or the like. A weight counterbalance adjustment mechanism adjustably compensates for various weights of a load held by the angled arm. Gas springs provide for vertical support of the angled arm. Configured slots in which the upper ends of the gas springs position provide for minimal manual positioning effort and a linear counterbalance throughout the entire range of vertical adjustment. An arm bent at an angle of 120.degree. overcomes the traditional interference of the load with movement of the arm beyond 45.degree..

  • Patent number: 5743503
    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.
