Furniture with adjustable work surface

Abstract

The present invention relates to a piece of furniture having at least one adjustable work surface. The furniture includes a mast, a work surface having a first mast hole, a torsion plate having a second mast hole that is fastened to the work surface, at least one torsion lever, a torsion spring, at least one handle, and at least one linkage. A user pulls the handle causing the torsion lever to reposition the torsion spring increasing the diameter of the torsion spring allowing the work surface to be slidably repositioned on the mast. The user then releases the handle causing the torsion lever to reposition the torsion spring such that the torsion spring constricts gripping the mast and preventing the work surface from moving horizontally or vertically along the mast.
