description

The invention relates to a traverse for a shelf.

Many types of shelves are known in the art. For example, the European patent application discloses EP 0273345 A2 a shelf, in particular a pallet rack, with suspended between upright shelf posts and / or attached longitudinal and / or transverse members as carrying elements.

WO 00/27733 A1 discloses a shelf with panels, wherein the panels can be used in recesses of traverses. Here claws of the trusses engage in lateral recesses of the panels.

WO 2010/022448 A1 discloses a shelving system with panels which can be inserted from above into recesses of traverses.

The invention has for its object to provide a cross member for a shelf. The object underlying the invention is achieved with the features of the independent claim. Preferred embodiments of the invention are indicated in the dependent claims.

There is described a shelf panel for a cross member of a shelf, the shelf panel having a U-profile with two opposing vertical legs and a vertical leg connecting the horizontal leg, wherein the vertical legs of the shelf panel at at least one end of the panel having opposite openings wherein the openings are completely enclosed by the material of the vertical legs, wherein the vertical legs are bent at right angles inwardly at least in the region of the openings at its end facing away from the horizontal leg end.

Such a shelf panel has the advantage that it can be used in a particularly simple manner in a Traverse a shelf. The openings in the vertical legs of the shelf panel serve to receive corresponding counter-locking elements, so that by simply inserting from above a locking of the shelf panel is made possible with the traverse. In the latched, ie assembled state then lie on the right angle inwardly bent parts of the vertical leg on the cross member of the shelf, so that acting through the shelf panel forces on the cross member are essentially mediated by these right angles bent elements to the crossbar. Due to the fact that locking elements can also act with the openings in the assembled, ie latched, state, an unintentionally becomes simultaneously locked in the latched state Movement of the shelf panel in the longitudinal direction of the shelf panel prevented. If, in the longitudinal direction of the shelf panel, the opening widens slightly beyond the width of the latching elements, it is possible to compensate for production tolerances of the shelf panel and the crossbar in the longitudinal direction of the shelf panel. If, for example, the shelf panel is suspended in a cross member, despite possible tolerances it is still possible to fix the shelf panel on its opposite side using said openings in the vertical legs of the panel on the opposite cross member of the shelf.

For example, has at the end of the panel, the horizontal leg on a recess, wherein the recess extends in the direction of extension of the panel completely to the end of the vertical leg of the panel. This results in the possibility of sinking the shelf panel at least partially in the traverse of the shelf. Thus, the shelf panel does not rest on the traverse, so that the highest point of the shelf panel towers above the traverse. Instead, it is now possible that the shelf panel either comes to lie slightly below the highest point of the traverse or even form the panel and traverse a substantially continuous flat surface. Overall, this increases the storage space within the shelf and unnecessarily protruding elements are avoided because the panel and Traverse together form a support surface for general cargo to be stored.

For example, in the region of the recess, the horizontal leg extends up to the recess and symmetrically to the recess. In other words, not the entire horizontal leg is recessed in the region of the recess, but left and right adjacent to the vertical leg part of the horizontal leg is still present. On the one hand, this increases the bearing surface of the shelf panel also in the area of the traverse, even if the shelf panel is mounted on the traverse. On the other hand, in combination with the orthogonally bent vertical legs, a U-profile results in the overlap area of the shelf panel and traverse, whereby the overall stability of the shelf panel is substantially increased.

For example, At the edge of the recess of the horizontal legs, it is inclined from the end of the panel pointing in the direction of the area between the vertical legs. Slope is understood to mean any angle ≥ 90 °. Such an inclination has the advantage that the assembly of the shelf panel is facilitated on a cross member, since a tab is formed by the inclined part of the horizontal leg, which serves as a stop against the traverse of the shelf. This facilitates threading of the shelf panel with its openings in relation to the counterpart latching elements of the traverse. Another advantage of using such a tab is that due to the bending of the horizontal leg in the transition region between the shelf panel and traverse sharp edges are avoided, so that stored material is not damaged when placing and sliding over the shelf panels.

For example, have the right angles bent inward legs in the region of the openings on recesses. These recesses prevent the shelf panel from slipping out of the traverse in the longitudinal direction of the shelf panel once the shelf panel has been inserted into the crossbeam. The recesses thus serve as an assembly aid in the assembly of the shelf panel of a traverse.

In one aspect, the invention relates to a cross member for a shelf, the cross member having a cross sectional profile having at least one vertical surface and a surface adjacent and inclined to the vertical surface, the crosspiece having two symmetrical recesses, each of which Recesses extends partially over the vertical surface and the inclined surface, wherein each of the recesses in the vertical surface has a horizontal edge and two edges inclined thereto, wherein the mutually facing outer inclined edges of the recesses each having a detent. By "inclined surface" is meant in comparison with the vertical surface of any inclination in the range between 40 and 90 °.

In such a Traverse can be used in an optimal and simple way, a corresponding counter-designed shelf panel, for which purpose the required assembly work is minimized. By using the inclined surface In addition, the storage of piece goods on corresponding shelf panels of the traverse is simplified because an abrupt transition between the vertical surface and the horizontal surface, which is defined by a corresponding shelf panel, is avoided. In other words, thus piece goods, which is located on the shelf panel, easily slide up to or even on the traverse and thus be moved in a simple manner.

According to one embodiment of the invention, the latching lugs of the two outer inclined edges to each other. This has the advantage that, by simply inserting a shelf panel in the symmetrical recesses of the traverse and due to the inclined edges, the vertical legs of a corresponding shelf panel are initially compressed when inserting, after overcoming the locking lug these vertical legs can snap apart again, so that in mechanical very simple way a locking operation can be realized. Preferably, the latching lug is formed as a projection of the respective outer inclined edge.

According to a further embodiment of the invention, the width of the recesses in the region of the inclined surface is at least as large as the width of the recesses in the region of the horizontal edge, wherein the width of the recesses in the region between the inclined surface and the horizontal edge is smaller than the width the recesses in the area of the horizontal edge. As already mentioned above, this makes it possible for a corresponding counter-piece shelf panel to be inserted into the traverse, wherein during the insertion process the shelf panel can no longer slip out of the recesses of the traverse in the longitudinal direction. As soon as the shelf panel is inserted into the recesses of the traverse, the outer inclined edges provide a forced guidance of the vertical legs of the shelf panel. The locking mechanism integrated in the traverse then follows a fixed fixation of the panel to the cross bar after forced operation after complete insertion of the shelf panel.

According to a further embodiment of the invention, a horizontal surface adjoins the inclined surface in the direction away from the recess. Preferably, the traverse is designed so that in the assembled state the horizontal leg of the shelf panel, ie the top of the shelf panel, comes to lie below the horizontal surface of the traverse, with the horizontal surface of the panel and the inclined surface of the Traverseinsgesamt results in a large contact surface of Traverse and Regalpaneel. The inclined surface of the traverse located between the traverse and the shelf panel prevents any piece goods stored in an unintentional manner on the shelf panels from jamming against the traverse. Thus, a storage of piece goods on corresponding trusses with opposing shelf panels is much easier. The fact that the top of the shelf panel is located below the horizontal surface of the traverse ensures that, for example, in the case of vibrations on the shelf panel located piece goods can not wander away by shaking the traverse and thus fall from the shelf. Thus, the inclined surface also forms a stop for general cargo to be stored, but without causing a risk of jamming.

According to a further embodiment of the invention, the cross-sectional profile is a pentagonal hollow profile, so that overall a high mechanical stability is ensured.

Further described is a shelf with a shelf panel described above and a traverse described above, wherein the width of the recesses in the region between the inclined surface and the horizontal edge is at least as large to accommodate the right angles bent inwardly legs in the region of the opening of the shelf panel , wherein the width of the recesses in the region of the inclined surface at least equal to the width of the right-angled inwardly bent part of the vertical leg of the shelf panel.

For example, touches in the mounted state, the inclined surface of the cross member partially the inclined horizontal leg, so that there is a limit stop between the shelf panel and traverse.

Process steps for mounting a shelf panel on a crossbeam.

The FIG. 1 shows a shelf 100 with extending in Regallängsrichftung traverses 104. The trusses are attached via known fasteners or types of attachment to respective braces 102 of the shelf 100.

The traverses 104 are connected to each other via shelf panels 106. That is, mutually opposite trusses 104 are each connected to one another by a plurality of shelf panels 106 arranged perpendicular thereto. For this purpose, in each case the ends 108 of the shelf panels are inserted into corresponding recesses 110 of the traverses 104.

The FIG. 2 shows a corresponding Traverse 104 in a perspective view. The traverse has a pentagonal cross-section profile with a vertical surface 112 and an adjacent to the vertical surface 112 and inclined surface 114. The inclined surface 114 in turn is followed by a horizontal surface 116 at. Traverse 104 has two mutually symmetrical recesses 110, each of recesses 110 extending partially over surface 112 and partially over surface 114. This results in the possibility of inserting a shelf panel 106 into these recesses 110 from above, ie in the direction 122. Each of the recesses 110 has in the vertical surface 112 a horizontal edge 124 and two edges 126 and 128 inclined thereto, wherein the mutually facing outer inclined edges 126 each have a latching nose 118.

The FIG. 3 shows an end 108 of a shelf panel 106 which fits into the recesses 110 of the crosshead 104, as in FIG FIG. 2 shown, can be used.

The shelf panel initially has a U-shape, which comprises two mutually opposite vertical legs 302 and a vertical leg connecting the horizontal leg 302 300. The vertical legs 302 have at least at the end of the panel opposite openings 304, wherein the openings are completely enclosed by the material of the vertical legs 302. In addition, the vertical legs 302, at least in the region of the openings, are bent at right angles inwards at their end pointing away from the horizontal leg, so that the elements of the vertical legs indicated by the reference numeral 308 result.

In addition, the shelf panel 106 has at its end 108 on the horizontal leg a recess 312, wherein the recess extends in the extension direction of the panel completely to the end of the vertical leg of the panel. However, in the region of the recess 312, the horizontal leg 300 is not completely recessed, but there is still an edge here, so that a U-shape results in connection with the elements 308 in the end region 108 of the shelf panel.

It can also be seen in FIG. 3 in that the right-angled inwardly bent parts 308 of the legs have further recesses 306 in the region of the openings 304. However, the right angle inwardly bent portions 308 of the legs are not fully recessed in the area 306, but in the area 306, the right angle inwardly bent portions 308 of the legs are still present. In the region of the recesses 306, the leftover part of the inwardly bent parts 308 of the legs can thus come to rest on a corresponding counterpart bearing surface of the traverses and thus support the panel on the traverse. The meaning of these recesses 306 will continue with respect to the FIGS. 4 and 5 explained in more detail.

Also evident in FIG. 3 is that at the edge of the recess 312, the horizontal leg is inclined from the end of the panel pointing away in the direction of the area between the vertical legs 302, resulting in the element 310 of the horizontal leg 300.

The FIGS. 4 and 5 show various sections of an assembly process of a shelf panel 106 on a cross member 104. First, the end 108 of the shelf panel 106 is brought to the traverse 104. As soon as the recess 306 encloses the inner edge 128 of the horizontal surface 112, the shelf panel 106 is pressed further in the direction 122 downward. Due to the inclined edge 126 of the recess 110 results in the insertion of the shelf panel a forced guidance of the vertical leg 302, so that they are urged towards 400, ie, the two legs in the direction of each other. By engaging the edge 128 in the recess 306 slipping out of the shelf panel 106 from the opening 110 in the extension direction of the shelf panel is now no longer possible.

If the shelf panel, as in FIG. 5 shown, has reached its final mounting position, a further positive guidance of the vertical leg 302 no longer takes place, since now the edge 126 engages together with the detent 118 in the opening 304. Due to the elastic properties of the vertical limbs 302, these now push back again in the direction 500, so that the overall result is a latched state of the shelf panel and traverse.

As also clear from FIG. 5 it can be seen forms in the assembled state of the horizontal leg 300 of the shelf panel 106 and the surface 116 has a nearly flat surface. The inclined surface 114 of the traverse prevents tilting of cargo when it is moved on the surface 300.

The FIG. 6 shows a schematic representation of a method for locking a shelf panel 106 with a Traverse 104 - on the left side of FIG. 6 in front view and on the right side of the FIG. 6 in a cross-sectional view of the cross member 104. For this purpose, the cross member 104 has the recesses discussed above 110, in which the L-shaped elements (projections) 308 can engage latching.

How to step in the Figures 6a - 6d First, the projections 308 of the shelf panel 106 are placed on the recesses 110 by a movement in the direction 122. As a result, the projections of the shelf panel 308 intervene more and more in the recesses 110, step by step. These recesses 110 form a backdrop with the in FIG. 2 discussed inclined edges 126 and 128. The vertical leg 304 and thus the projections 308 are thereby compressed in the direction 400 until finally the in FIG. 6d shown stop position is reached. This causes, as in FIG. 6d shown in the assembled state, the vertical leg of the shelf panel again push apart, so that now the locking lugs 118 formed by the edge 126 engage in the openings 304 of the shelf panel. In the mounted state, ie in the stop position, the L-shaped ends 308 of the shelf panel are located on the cross member 104, whereby the load application is optimized for the traverse.
