摘要： 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.
摘要翻译：用于桌面（2）的底架的主要部件是安装板（19），腿柱被紧固在其上，两个安装导轨（17）布置在桌面（2）的下侧（5）上，距离并且彼此平行，并且两个夹紧装置（7）将安装板（19）牢固地夹紧到安装轨道（17）。安装导轨（17）是具有短的加强腿（17a）和长的保持腿（17b）的L型铸造型材，其通过夹紧螺栓（17c）固定到桌面下侧（5）上;或者模制的夹紧腿，向下偏移。紧固螺柱（17c）或夹紧腿指向桌面的中心，与保持腿（17b）形成一个槽（18），以将桌面（2）移动到安装板（19）的外边缘（19a）上）向上偏移或延伸安装板。在安装板（19）上，具有用于致动锁定杆（21）的肘节（20）的两个夹紧装置（7）以一定距离附接，杆配合在其夹紧端（21'）的锁定位置（17）和安装板（19）的外边缘（19a）之间的夹紧支柱（17c）形成的夹紧间隙（23）），布置在螺柱（17c）或夹紧腿上一定距离处。
