The invention shown in Figure 1 Cantilever rack has several T-profile stands (1), at least two stands for one shelf. The number of Stand is arbitrary. T-profile stand (1) can be in the same or unequal intervals. At the illustrated embodiment are these T-profile stand (1) designed as a double T-profile stand. In the flanges (2) of the profile stand (1) are pairs of Die cuts (3) arranged. The die cuts (3) one each pair are at the same height and are at a distance from each other and one above the other in the flanges (2) arranged. These punching pairs (3) can be in one Flange (2) or in both flanges of a double T-beam (1) be present. At the bottom of the stand (1) are Support feet (14) attached. Can between the stand (1) known spacers (15) and diagonal Tension bandages (16) with tensioning screws (17) can be arranged.

As can be seen from FIGS. 2 and 3, they point into the Punched out (3) cantilever arms (4) on fastening-side end of foot plates (7) with hooks (5), each paired horizontally through a few punched-outs (3) can be pushed through in some areas, with the push-through area (6) of each hook (5) one for horizontal inclusion of one blocking element (20) trained recess (8) is present. Like the Figure 2 with inserted through the recess (8) Locking element (20) removable, this is a Power transmission optimally designed locking hooks (21) from robust and uncomplicated design and preferred a forged part made from tempered steel.

As shown in detail in FIGS. 5a and 5b show a circular shaft (22) with a locking lug (23) and has a handle (24) for its actuation on. This can be rectified with the locking lug (23) be arranged, as shown in Figure 2. The Locking hook (21) is with upward Handle (24) and locking lug (23) in the upward self-locking z. B. oval recess (8) like introduced a key and then in the direction of the arrow (19) on the handle (24) swiveled 180 degrees, whereby the locking lug (23) in the lower, shown in dashed lines Swings position and the recess (8) such engages behind that the locking element (20) in the dashed line drawn position is locked laterally. this is the only one step for attaching a cantilever (4) with the footplate (7) and the hook (5) on the flange (2) a T or double T beam.

From Figures 4a to 4c it can be seen that the Base plate (7) in a preferably one-piece design U-shaped cross section with a crossbar (10) and the sides of which have longitudinal webs (9) at one end the hooks (5) are arranged protruding. In the hook (5) are for pushing through a locking element (20) trained recesses (8) available. This recess (8) can preferably be one of the circular shape deviating, elliptical, elliptical or have an oval or slot-like shape. Still is in the crosspiece (10) of the footplate (7) on which the hook (5) opposite end one for receiving one Adjustment element trained recess (11) available. It can be seen from Figure 2 that the adjusting element can be any screw that varies depending on Screwed state more or less far against the inside of the flange (2) supports and thereby a correction of Horizontal position of each cantilever (4) in the simplest and economically.
