ABSTRACT:
An exemplary apparatus for counterbalancing a video display comprises a stationary housing, a boom rotatably fixed to the housing which supports the video display, a counterweight boom disposed within the housing and below the boom for counterbalancing the torque imparted on the boom by the video display, a coupling member which mechanically couples the counterweight boom to the boom such that they move in unison, and a stabilizer which limits the speed at which the boom and counterweight boom travel to prevent injury to users. The location of the counterweight boom inside the housing and below the boom results in a lower center of mass of the apparatus which significantly improves stability.
