CA 2178142

A freestanding table having a worksurface supported on height-adjustable legs, each having a height- adjusting mechanism. These mechanisms are simultaneously driven through a driving element such as an endless chain driven by a driving sprocket disposed adjacent the underside of the worksurface. The driving sprocket is nonrotatably connected to a rotatable hub supported in a recess in the worksurface, which recess also accommodates a foldable crank. The crank when in a folded and stored position is disposed in the recess so as to be substantially flush with the upper surface of the worksurface. The crank is pivotally joined about a first axis to an intermediate link which in turn is pivotally joined about a second axis to a rotatable hub so that the crank can be pivoted upwardly through an angle of about 180° so as to be disposed above the worksurface to permit manual gripping and hence rotation thereof when height adjustment is desired.
