1. Assembly stand with a vertical support (1), consisting of a rectangular hollow section, on the side wall of which at least one horizontal bracket (5) is mounted, which is provided with a flange and is vertically adjustable and able to be clamped by means of a clamping device, whereby in the side wall of the bracket (5) an elongated slit (3) is left open, the inwardly bent edges of which each have inwardly directed teeth, into which a holder (9) of the clamping device engages, which is able to be introduced through the slit and is rotatable through 90 degrees, whereby also on the holder a spring-loaded, tensile clamping element is arranged, which is connected with the bracket (5) and presses the flange of same against the side wall of the support, characterized in that the holder (9) has two parallel grooves (10) in which the toothed longitudinal edges of the slit are carried with play, that in each of the grooves (10) at least one detent is arranged, which engages into the teeth (4), and that the two surface zones (9a) of the holder (9) lying laterally outside the grooves (10), are constructed as flat contact pressure surfaces, which under release of pressure of the detents and of the teeth (4) transfer the contact pressure onto the side wall of the support. |
