ABSTRACT:
An adjustable height stand for a visual display unit incorporates a column adjustably mounted within a base part, with a gear train for effecting vertical adjustment. The gear train incorporates a helical gear arranged with its axis in parallel with the column, and cooperates with a gear part mounted to the column. The helical gear may be rotated by a hand wheel through a gear train incorporating a pair of meshing bevel gears. Alternatively, the helical gear may be driven by a motor. The stand is rotatable relative to the work surface about a vertical axis, and the visual display unit is tiltable relative to the support. The spring is provided for compensating for the weight of the visual display unit.
