First, reference is made to FIGS. 1 and 2. There are Shelves according to the invention can be seen which vertical stand 1 include those with foot parts 2 lying on the floor are connected. Both the stand 1 and the foot parts 2, 2 'are preferably hot-rolled I-beams, since they are one have high stability and the forces acting on them can catch well. There are also cantilever arms 3 can be seen, which in suitable openings 10 of the stand 1st are attached. The arms 3 are used to attach in Floor plan in approximately rectangular shelves 4. As later is explained, the arms 3 have a certain forward inclination on, that is, their cantilevered ends are slightly upward directed. This also results in a corresponding inclination of the with the arms 3 optionally connected shelves 4. Thus, stored material (not shown) tends to tend a movement in the direction of the stand 1 and can not easily fall off the shelf. The use of the shelves would be under Under certain circumstances, however, also conceivable without shelves 4, for example for the storage of bar stock. To secure against Vertical roll-off protections 7 can also be unrolled be provided. The roll-off protections 7 are located preferably in the region of the projecting ends of the arms 3. The shelves have a longitudinal direction L, which by the Stringing together several stands 1 and can of course be extended as required. For stabilization of the shelves (longitudinal bracing) have this Stabilizing components in the form of horizontal Distance profiles 5 (preferably C profiles) and diagonal Stiffening bands 6 (preferably flat iron). On the Suitable base plates 8 can be attached to base parts 2. Furthermore, an additional securing of the foot parts 2 can be done by means of Securing claws 9 take place, which in cross section approximately are hook-shaped and after screwing with the Cover the foot parts 2 partially. With the foot parts 2 can mounting plates 50 for lower roll stops be attached. Furthermore, the stand 1 for hanging other useful components, such as Bar strips 51 serve.

3 to 6 that the stand 1 I profiles are and each flange of a stand 1 with the already mentioned openings 10 is provided, the Openings 10 made rectangular and on both sides of the web are arranged. The openings 10 are in the longitudinal direction of the Stand 1 preferably at a distance of about 50 mm screened. Furthermore, the webs of the stand 1 in bottom and top, each in rectangular openings 11 approximately in the middle of the web, whose function will be explained later. For fixing the stand 1 on the foot parts 2 are the stand 1 on their the foot parts 2 facing end faces with in plan welded approximately rectangular plates 12. The plates 12 each have two bores 120 in the area of their ends. Likewise, the one facing each plate 12 Flanges of the foot parts 2 with corresponding holes 20 provided so that the stand 1 and the foot parts 2 by means suitable fastening means 13, for example screws, can be connected. The assembly can thus easily take place at the site, which is a very enables efficient logistics because the individual parts of the Storage nested very space-saving until transport can be.

The fact that both flanges of a stand 1 with the Openings 10 are provided both very easily single-sided shelves (Fig.1) as well as double-sided shelves (Fig.2) are built. Also a subsequent conversion existing shelves from one-sided to double-sided Execution and vice versa is easily possible by just the foot parts 2 and 2 'are exchanged. The foot parts 2 ' are approximately twice as long as the foot parts 2, the Bores 20 in the foot parts 2 'in about half their length are arranged so that after assembly The foot part 2 'extends from the stand 1 on both sides (cf. FIG. 5 and 6). In the foot parts 2, the holes 20 are in the area their ends arranged (see. Fig. 3 and 4).

7 a and 7 b is the structure of the cantilevered arms 3 shown in more detail. These essentially include an off several walls curved, elongated profile, which in its outer outline is roughly the shape of a rectangle has, with an upper transverse wall 31, two Longitudinal walls 30 and two lower transverse walls 32, the are each approximately half as wide as the upper transverse wall 31. The transverse walls 32 close upward in approximately 90 °, walls 33 curved in the direction of the upper transverse wall 31. Because the profile consists of bent walls, is a high degree of flexibility in the needs-based Design of the profile achieved with ease of manufacture. The walls 33 are therefore approximately perpendicular to the Transverse walls 31 and 32, respectively. The walls 30, 31, 32 and 33 are bent into an essentially closed profile, wherein the walls 33 touch or at least only one slight gap S remains between them. The Walls 30, 32 and 33 form in cross section in the lower Area therefore roughly the shape of two open and adjacent C-profiles. Of course, it is also conceivable that the Walls to be bent to other profiles, for example to triangular or polygonal profiles. The outside however, the substantially rectangular shape offers special Advantages in terms of stability and ease of installation.

As can also be seen from FIGS. 7 a, b, the Walls 33 provided with slot-like recesses 34, which always in pairs over the entire length of the arm 3 are distributed. The recesses 34 extend in here approximately perpendicular to the longitudinal extent of the walls 33 and in about their entire width. Between every pair of Recesses 34 practically remain a wall area W der Walls 33. The upper transverse wall 31 is with rectangular openings 35 provided at a distance of about 100 mm are arranged. Show the same grid also the wall areas W, so that an opening 35 corresponding wall area W is opposite. It is each have a wall area W, perpendicular through an opening 35 considered smaller than the limit of the respective opening 35. In this way, a Roll-off protection 7, for example in the form of a commercially available rectangular tube, from above through an opening 35 through and on the corresponding wall area W be plugged on. The roll-off safeguards 7 thus have adequate hold on being an unintended Falling out or a risk of injury from down protruding parts is not possible. The cutouts 34 can also be made wider, but this is one Loss of stability and increased material waste would have. On the longitudinal walls 30 are also approximately rectangular recesses 36 can be seen, which for receiving Collar nuts or round screws for fastening the Shelf 4 serve.

The bending of the walls to a desired profile for a cantilevered arm can be most advantageous by means of Profile reshaping (roll profiling).

A hooking claw 37 is also used as the hooking means provided which matches the profile of the cantilever arm 3 connected, preferably welded. The hook claw 37 is approximately U-shaped in cross-section with a U-leg forming walls 372, to which upper and lower Hooks 370 and 371 are formed. The amount of between Hooks 370, 371 lying walls 372 takes, starting from the upper hook 370, too. This can already be a Forward tilt of the cantilever arms 3 can be achieved without the cantilevered arms 3 even when cutting to length as required must be cut obliquely.

8 to 10 is the attachment of the Stabilizing components 5.6 shown in more detail. These are in Area of the openings 11 preferably by a Screwed 200 fastened with connecting elements 100. How 10, in particular, are the Connection elements 100 flat, elongated components, wherein two connection elements 100 each by a rectangular Opening 11 in the web of the stand 1 are inserted through. Each connection element 100 has an end 101, which is at least partially larger than the height of the Opening 11 and another end 102, which is smaller than the height of the opening 11. This results in a bilateral Paragraph 105, which when inserting a connector 100 supports against the web of the stand 1. The width of the The end 102 corresponds approximately to the height of the opening 11 or is preferably only slightly smaller than this. The Thickness of a connecting element 100 corresponds approximately to that Half the width of the opening 11 or is preferably only slightly smaller than this. This leads to a safe one Halt and to a substantially vertical form fit the Connection elements 100 in the opening 11 before Screw connection with the stabilizing elements 5, 6. Each Connection element 100 has at its end 101 approximately circular bore 103 and at its other end 102 one Longitudinal bore 104, which are used for screwing. Through the Longitudinal bore 104 may facilitate screwing, since the holes 103, 104 do not have to be exactly aligned.

10 makes it clear that each of the two has an opening 11 associated connector 100 from another side of the Web wall of the stand 1 is inserted through. The Dimensions of the connection elements 100 are to be selected that after screwing (see. Fig. 8 and 9) the horizontal spacing of paragraphs 105 of the first Connection element 100 to those of the second connection element 100 approximately the thickness of the web wall of the stand 1 corresponds. In this way, after screwing Stabilizing elements 5,6 with the connection elements 100 Form-fit acting in the longitudinal direction L of the shelf is achieved. Other forms of connection elements 100 are admittedly also conceivable, but the connection elements 100 shown easy to manufacture and only require the introduction of Openings 11 in the stand 3.

11 to 14 is shown in more detail how the cantilevered arms 3 by means of the hooking claws 37 in the Stand 1 can be hung. As with FIG. 11 can be seen, each lower hook 371 has an approximately horizontally running hook back 3710, which in a Recess 373 in the wall 372 merges. Compared to the Hook back 3710, at the lower end of the hooking claw 37 another recess 374 can be seen in the hooking the flange wall of the stand 1 is partially accommodated. The recess 374 becomes one side by a front one Contact area 3740 limited. Bending radii are also 376 recognizable by the u-shaped bend of the Hook claw 37 are caused.

Furthermore, a securing means 38 can be seen which a threaded bolt 380, a square nut 382 and an im Outline roughly square locking plate 381 includes. Of the Threaded bolt 380 is connected to the Locking plate 381 rotatably connected. The locking plate 381 has tab-like on two opposite sides, in bent approximately at right angles in the same direction Formations 3810 on in the opposite direction like the threaded bolt 380 point. Before hanging the Hooking claw 37 becomes the securing means 38 inside of the hooking claw 37, the threaded bolt 380 from the inside through a in the rear wall of the suspension claw 37 located lower opening 375 is inserted and the tab-like projections 3810 in the recesses 373 space find (see Fig. 12).

13a shows the securing means 38, the Square nut 382 not yet on the threaded bolt 380 is screwed on. The square nut 382 has one annular contact surface 3820 on all sides in a curvature 3821 going to the edges of the square nut 382 transforms. In Fig. 13b is the pre-assembled state of the Securing means 38 shown. The square nut is 382 screwed as far as possible onto the threaded bolt 380, whereby the annular contact surface 3820 to the locking plate 381 turned away and the distance between square nut 382 and Locking plate 381 is minimal. This takes that Securing means 38 initially takes up little space and can essentially picked up by the hooking claw 37 become. In addition, the projections 3810 are not forward over the recesses 373 (see Fig. 12). So is a proper hooking of the hooking claw 37 into the stand 1 guaranteed. Due to the square shape of Locking plate 381 and square nut 382 can do that Securing means 38 with suitable dimensions on simple Place it in the hook claw 37 so that it cannot twist.

Fig. 14 shows the assembled state of two cantilevered Arms 3 on a stand 1 together with securing means 38 the hooking of the hooking claws 37 is done by Turn the threaded bolt 380 clockwise using a suitable one Tool, for example an Allen key, the Locking plate 381 away from the square nut 382, in Direction of the stand 1 moves. This pushes them tab-like projections 3810 in the openings 10 of the Stand 1 and fill the remaining space between the Limitation of the opening 10 and the hook located therein 371 at least in the vertical direction so far that a vertical movement of the hook claw 37 substantially is blocked.

By turning the threaded bolt 380 clockwise, the Distance between the locking plate 381 and the Square nut 382 finally so large that the Square nut 382 with its annular contact surface 3820 from the inside presses against the rear wall of the hooking claw 37 and the lower part of the hooking claw 37 as far outwards moved until the front contact surfaces 3740 (see. Fig. 11 and 12) against the flange wall of stand 1. Due to the curvature 3821, the force is transmitted the rear wall of the suspension claw 37 essentially only over the annular contact surface 3820, as an undefined Contact of the edge areas of the square nut 382 with the Bending radii 376 of the hooking claw 37 is avoided. By the actuatable securing means 38 can thus be a further one Advantage despite possible thickness tolerances in the Flange walls of the stand 1 a uniform inclination the cantilevered arms 3 can be achieved.

Disassembly of the arms 3 is after turning the left Threaded bolt 380 and thus loosening the securing means 38 easily possible.
