ABSTRACT:
An adjustable monitor stand for pivoting a monitor about a horizontal axis which is relatively simple to operate and which does not require great effort to adjust is provided. The stand includes a base, a platform for holding the monitor, and a hinge interconnecting the base and the platform. The hinge includes a torsion spring selected with regard to the mass of the monitor and the distance of its center of gravity from the axis so that the gravitational torque produced as the monitor is pivoted with the platform about the horizontal axis is always substantially balanced by the restoring torque generated by the spring. The stand therefore requires very little effort to adjust.
