Description

The present invention relates to a shelf for a shelf, wherein below the shelf level for stiffening on the transverse sides of the folds and longitudinal sides of the shelf longitudinal channels are provided.

It is already known to stabilize the shelves in metal shelves by bends on the transverse sides down on the one hand and on the other hand by extending below the shelf level longitudinal channels on the long sides. In these shelves, however, it has proved to be disadvantageous that the said longitudinal channels tend to rotate outward under load of the shelf, so that in principle increases the width of the shelf at greater load.

Object of the present invention is thus to provide a shelf for a shelf of the type mentioned, in which this is avoided and a higher torsional stability is achieved.

The solution to this problem provides a shelf for a shelf of the type mentioned above with the characterizing feature of the main claim. According to the invention, at least one tension strut running at least partially in the diagonal direction is provided on the lower side of the shelf in at least one corner area. Preferably, such tension struts are provided in all four corner areas on the underside of the shelf. Under diagonal direction is to be understood that this tension strut extends at least partially at a distance from the corner approximately parallel to the diagonal of the shelf between the longitudinal channel and the stiffening on the transverse side of the underside of the shelf. The longitudinal channel is inventively stabilized in that the tension strut is connected to the material of this longitudinally extending channel of the shelf. This can for example take place in that this tension strut as a on the plate of the longitudinal channel formed flap is formed. In this preferred variant of the invention is particularly advantageous that the shelf can be made in total from a contiguous sheet metal blank. In principle, it would also be possible to weld the tension strut, for example, to the longitudinal channel or to install it by fastening means there.

A preferred embodiment of the invention provides that the tension strut has at least one parallel to the fold of the shelf in the transverse direction extending bevel, which is connected to this transverse edge, preferably by welding or possibly also by fasteners. In principle, it would also be possible to form the tension strut on the transverse edge and to weld it to the longitudinal channel, that is to say in principle, conversely, to the previously described preferred solution.

It is important within the scope of the invention, however, that the tension strut allows a flow of force from the longitudinal channel in the transverse edge, which extends at least partially over a diagonal to quasi support the longitudinal channel against the transverse edge and thereby increase the torsional stability of the shelf.

A further increase in the stability of the shelf is preferably achieved in that the tie rod has at least one Anformung or fold parallel to the ground plane of the shelf, which is preferably also connected to this bottom plane, that is, so with the bottom of the support surface of the shelf. This creates an additional connection of the tie rod to the ground plane of the shelf and can initiate forces there in a direction that is perpendicular to the main plane of the tie rod. For example, the tie rod can be welded to the underside of the bottom plane of the shelf.

The said longitudinal channels of the shelf are preferably substantially closed channels with four walls, at least over part of the length of the shelf, the channels usually ending at a distance from the corners. An increased rigidity of the shelf is preferably produced by the fact that the longitudinal channels have an approximately M-shaped profile. This M-shape includes a bead around the top center that stiffens the M-channel. This longitudinal channel may also be supported by parts at the bottom level of the shelf, e.g. by providing a fold which projects perpendicularly inwards from the longitudinal channel and thus runs parallel to and can be connected to the floor plane of the shelf, e.g. by welding. A further stabilization of the shelf can be achieved by extending preferably the folds of the transverse sides beyond the corner by right-angled bends so that they overlap with extensions of the longitudinal channels in the form of simple bends, which can also be done in these overlapping areas a weld ,

A further increase in the shelf load and a stabilization of the shelves to prevent deflection can be achieved according to a preferred embodiment of the invention by joists, these joists preferably extend in the transverse direction below the ground level of the shelf. The joining of the beams with the shelves can be done, for example, by the fact that the beams have insertion ends which can be inserted into a slot of the longitudinal channels. In this case, further, pronounced cams are preferably present on the underlays at the ends of the material, which cams after insertion of the insertion ends of the beams into the slot behind the wall of the longitudinal channels. This allows a particularly simple installation by simple Insertion and locking of the beams without additional necessary fasteners.

The present invention further relates to a shelf comprising corner posts and at least one shelf, preferably a plurality of shelves with the features of one or more of claims 1 to 12. A further stabilization and stiffening of such a shelf is achieved when at least one of the shelves in the Corners stiffening surfaces arranges, which are fastened to the corner posts on the one hand and folds on the long side or transverse side of the shelf on the other. This attachment is preferably done by screwing. These stiffening plates may for example have an angular shape.

Since the above-mentioned tie rods of the shelves partially obstruct the corner space below the shelf level and thus complicate screwing from the inside of the shelf ago, it is preferably provided that the stiffening plates are provided with integrated threads or nuts so that they from the outside of the Shelves or corner posts forth, for example, by appropriate screws that are simply screwed into the integrated thread, can be fastened. As integrated nuts, for example piercing nuts, weld nuts, Einpressmuttern, cage nuts or the like into consideration or it can be formed directly in the metal thread. Depending on the desired load of the shelf, it is sufficient if one or more of the superimposed shelves are provided with such stiffening plates.

A shelf according to the invention may consist of a basic shelf with usually several superimposed shelves and four corner posts. Such a basic shelf can be longitudinal be extended by cultivation shelves with other superimposed shelves and at least two other corner posts.

The features mentioned in the dependent claims relate to preferred developments of the shelves or the shelf shelf according to the invention. Further advantages of the invention will become apparent from the following detailed description.

First, reference is made to Figs. 1 to 3. Fig. 1 shows the blank 100 for a shelf of a shelf according to the invention before the various bending operations are performed. This sheet metal blank 100 is folded so that two longitudinal channels 2 with an approximately M-shaped cross section are formed in the longitudinal direction of the shelf on the underside. These longitudinal channels 2 can be seen in FIG. 2 and their cross section can be better seen in FIG. On the transverse side of the shelf bottom is trimmed three times and that once perpendicular to the shelf level 7 down, from there again vertically inwardly and then again in a shorter fold in the direction of the shelf level 7, as can be clearly seen in Fig. 3. In the statically stressed areas of the shelf 100 is optionally reinforced by spot welds. These areas usually include the four shelf corners and the two longitudinal channels 2.

The construction of the shelf 100 in the corner area can be seen particularly well in FIG. 3. There you can see that in the area of the corners of the longitudinal channels 2 outgoing and in the Usually at these integrally formed tie rods 5 extend approximately at an angle of for example 45 ° in the direction of the transverse edges 3, so that these tie rods 5 can be connected, for example by spot welding with the transverse edges 3. From Fig. 1 it can be seen that the to be formed on the longitudinal channels 2 tie rods 5 are connected to the plate of the longitudinal channels 2 and are present in the sheet metal blank for the shelf 100 as a rag. These tie rods 5 cause the turning out of the longitudinal and transverse edges of the shelf is avoided or greatly reduced under load of the shelf. These tie rods 5, as can be seen from FIG. 3, further recognizes on the underside a 90 ° bend 6 in the direction parallel to the ground plane 7 of the shelf. Again, a connection with the ground level 7 of the shelf is possible for example by spot welding. By this measure, the torsional rigidity of the shelf is increased. As you can see, the fold 6 in plan view, for example, a trapezoidal shape.

As a further measure to stabilize the shelf corner areas, the bends 3 are bent at the transverse sides of the shelf at the end at an angle of 90 ° in the direction of the longitudinal channels 2, so that there are the bends 8. Thus, one can see the bends 8 of the Querseitenabkantungen 3 e.g. connect by spot welding directly with the arranged in extension of the longitudinal channels 2 longitudinal edges 9. In the area of these folds 8 and 9, therefore, a material doubling results in the direction of the longitudinal channel 2, which is used to stabilize the shelf, e.g. when using shelf supports in the Steckregalsystem serves.

Alternatively, you can also the arranged in extension of the longitudinal channels 2 longitudinal side folds 9 at right angles inwards edge, so that they overlap with the bends 3 on the transverse sides and can be connected to them, so that even in this case a material doubling leads to a stabilization of the shelves in this area.

The longitudinal channel is provided at the top and bottom with a hole in a grid with regular intervals. This perforation is designated 10 in FIG. If required, divider can be inserted in the depth direction. To allow a better stacking of the shelves, stacking cam 11 and corresponding fishing holes 12 are present.

In the following, reference is made to FIGS. 11 to 15 and on the basis of this the possible use of additional beams 14 is explained. The shelf has about V-shaped arranged slits 13 in the region of the longitudinal channels 2, which can be seen in particular in Fig. 12 well. These serve to receive end-side projections 14a of the beams 14, which are shown in FIG. These projections 14a are inserted in the transverse direction into the slots 13. The beams 14 have the task of reducing the bending of the ground cover surface 7, which forms the shelf level (see Fig. 3) at higher loads. The beams continue to serve to increase the permissible load. In order to prevent falling out of the beams 14, pronounced cams 15 are preferably present at their ends. These cams 15 can be seen in Fig. 13. In the installed state, these cams 15 are in the longitudinal channel 2. The fixed predetermined installation positions ensures that the beams 14 are always kept in its ideal position both in the longitudinal direction and in the transverse direction of the shelf become. An unintentional shifting of the beams 14 is not possible. The expansion of the beams is made possible by squeezing the ends and simultaneous axial displacement.

In the loaded state of the shelf, the beams 14 direct the normal force into the longitudinal channels 2. For this reason, the longitudinal channel 2 is preferably connected in the region of the V-shaped slits 13 by spot welds 16 directly to the bottom plate 7 of the shelf level. The beams 14 are usually available in different standard lengths corresponding to the respective width of the shelf.

The method for installing the beams 14 in the respective shelf can be explained with reference to Figures 14 and 15. First, the respective beam 14 is brought to the height of the V-shaped slot 13 and the end 14 a of the beam (see also Fig. 13) is inserted into the slot 13. Subsequently, a pressure is exerted in the axial direction of the beam 14 until the cams 15 shown in FIG. 13, which are stamped out of the material of the beam, engage behind the outer wall of the longitudinal channel 2. The first assembly stage is shown in Fig. 14, so that you can still recognize the cam 15 there. Fig. 15 shows the final stage of assembly, in which the cams 15 lie in the longitudinal channel 2.

Hereinafter, reference is made to FIGS. 7 to 9. Fig. 7 shows in the left half of the illustration, a base shelf 22 with a series of superposed shelf levels 21, 20, which are respectively secured to the corners arranged in posts 19. In the longitudinal direction of the shelves 21, such a basic shelf 22 by a corresponding cultivation shelf 23, which is shown in Fig. 7 right, extendable. The shelves according to the invention are constructed so that they can be installed both in plug-in shelves as well as in screw shelves. In a plug-in shelf, the shelf is fixed either with shelf supports or longitudinal bars. In a screw rack, the shelves by screws, for example, hexagon socket head flange screws, which are designated by the reference numeral 17 in Fig. 8, and secured with stiffening plates 18. A special feature of the stiffening plates 18 is that these piercing nuts have 18a, as can be seen from the detailed illustration of such a stiffening plate 18 as shown in FIG. Loose collar nuts can also be used.

These stiffening plates 18 serve to stabilize the Schraubregals in the longitudinal and transverse directions. The measure, the stiffening plates already factory provided with piercing nuts 18 has the advantage that then the screw can be made from the shelf outside as shown in Fig. 8. Thus, it is not disturbing that the diagonally extending tie rods 5 are arranged on the inside in the corner regions, as can be seen in Fig. 9 and also in Fig. 3. The shape and the manner of attachment of the tie rods 5 would complicate attachment from the inside because of the poorer accessibility. This is avoided by the use of the piercing nuts 18.

A shelf according to the invention may have a different number of stiffening levels. The respective stiffening levels are designated in FIG. 7 at the base shelf 22 on the left and the mounting rack 23 on the right with the reference numeral 20. The number of stiffening levels 20 depends on shelf height and field load. The shelf levels without stiffening plates, which are designated in Fig. 7 with 21, for example, can be fixed only with pan head screws and collar nuts. The piercing nuts 18 are not necessary here, since the stiffening plates 18 are omitted in these shelf levels 21. As a rule, two stiffening plates are used in a stiffened shelf 21 in each corner region, as can be seen in FIG. 9.

Thus, eight stiffening plates are present per stiffening plane in a basic shelf 22 of the type shown on the left in FIG. For the cultivation rack 23 as shown in FIG. 7 right one needs four more stiffening plates for the two additional added corners of the shelves 20 with the two other posts 19th

In the shelves 20, 21 there are usually a number of standard sizes with different standard lengths and different standard widths, where width here the depth of the shelf is meant according to the aforementioned transverse direction of the respective shelf. Depending on the dimensions of the respective shelves and the intended compartment load, the shelves are made of different material thicknesses. This raw raw sheet material or galvanized sheet material can be used.
