Abstract
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.degree. so as to be disposed above the worksurface to permit manual gripping and hence rotation thereof when height adjustment is desired.
