Abstract
A height adjustable desk including a work bench which is height adjustable and supported upon a pair of upwardly extending legs. The leg includes an upper portion supported on a lower portion. A height adjustment mechanism is manipulated by the user to adjust the height of the upper portion. This motion is transferred to the upper portion of the leg by means of cooperating rack gears meshingly engaged with their associated pinion gears. A shaft couples the gears so that the upper portions move in unison. The height adjustment mechanism includes a cooperating worm gear and nut. The worm gear is supported by the upper portion, while the nut is mounted in the lower portion.
