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.

A stand for supporting an object above a surface, said object having a mass and a center of gravity, such that said can be rotated about a horizontal axis between two extreme angular positions, said center of gravity being at a distance from said axis, said stand comprising: base means for resting on said surface; platform means for holding said object; and hinge means linking said base means and said platform means, said hinge means comprising: a hollow axle aligned with said axis and having first and seconds ends, said axle having first and second tube sections, each of said sections having an end remote from its respective axle end and an extension at said remote end extending less than 180 degrees about said axis, said first and second axle sections abutting with said extensions in overlapping relationship, said extensions forming stop means defining said extreme positions, first and second means on said base for receiving said first and second ends, respectively, of said axle, means on said platform for rigidly engaging one of said first and second tube sections, and spring means capable of torsional deflection disposed within said axle, one end of said spring means being rotationally fixed relative to another of said first and second tube sections and another end of said spring means being rotationally fixed relative to said one of said first and second tube sections, such that relative rotational movement of said base means and said platform means creates a restoring a torque in said spring means, said spring means having a torque constant selected with regard for said mass and said distance so that said restoring torque substantially balances gravitational torque acting on said center of gravity when said platform means holding said object is rotated to different angular positions between said extreme positions.
