ABSTRACT:
A worktable, particularly an office desk, having a top adapted to be adjustable as to height and inclination. The top is supported on four vertically adjustable columns, each of the two columns of the pair of columns in front and the two columns of the pair of columns in the rear are jointly adjustable in guides provided in the trestle. To selectively adjust the height and inclination of the table top, latch receptacles are provided on all columns spaced along their length to receive compression spring urged locking pins installed in the trestle. Each of the pair of support columns is associated with a lever mechanism by means of which each pair of support columns can be rotated, the latch connection unlatched and, upon adjustment of the pair of columns, the latched position re-established.
