ABSTRACT:
Main components of the underframe for a tabletop (2) are a mounting plate (19), on which a leg column is fastened, two mounting rails (17) arranged on the underside (5) of the tabletop (2) at a distance from and parallel to one another, and two clamping devices (7) clamp the mounting plate (19) firmly to a mounting rail (17). The mounting rails (17) are L-cast profiles with a short reinforcing leg (17a) and a long holding leg (17b), fastened to the tabletop underside (5) with clamping studs (17c): or a molded-on clamping leg, offset downwardly. Clamping studs (17c) or the clamping leg, directed toward the center of the tabletop, form with the holding leg (17b) a slot (18) to move the tabletop (2) onto outer edges (19a) of the mounting plate (19) offset upwardly or to extend the mounting plate. On the mounting plate (19), two clamping devices (7) with a toggle joint (20) for actuating a locking rod (21) are attached at a distance, the rod fitting in locking position (21') with its clamping end (22) into a clamping gap (23), which is formed by clamping studs (17c), each in the locking position, or the clamping leg of one of two mounting rails (17) and outer edge (19a) of mounting plate (19), arranged at a distance over studs (17c) or the clamping leg.
