Shelf uprights for cantilever racks

Abstract

Shelf upright for cantilever racks, comprising a shelf base and a vertical shelf column arranged on the shelf base with recesses in which retaining profiles can be arranged, characterized in that the shelf column is formed at least with at least one sheet metal bending part extending along a longitudinal direction of the shelf column.

Description

[0001] The present invention relates to a shelf upright for cantilever racks. The shelf upright comprises a shelf base and a shelf column arranged vertically on the shelf base in the operating position. Recesses are arranged in the shelf column into which retaining profiles can be inserted. The recesses are also referred to as insertion openings and the retaining profiles as brackets. Shelves, for example, can be placed on the retaining profiles arranged in the recesses of two adjacent shelf uprights. Goods can then be placed on these shelves. Adjacent shelf uprights can be connected to each other or connectable to each other to create a corresponding cantilever rack.

[0002] The support profiles form cantilever arms. Loads placed on these cantilever arms must be absorbed by the upright and transferred to the floor via the base of the upright. In conventional uprights, the uprights are typically designed as square support tubes. Alternatively, round or polygonal tubes, especially tubes with 6, 8, or more edges, can also be used. Depending on the expected load, support tubes with specific wall thicknesses and dimensions are used. The greater the expected loads on the cantilever rack formed with the uprights, the larger the dimensions of the square tubes. For the production of such uprights, square tubes are typically available in specific, predefined dimensions. Adapting the square tubes is either impossible or only possible with disproportionate effort.

[0003] The object of the present invention is to provide shelf stands that can be manufactured using less material.

[0004] According to the invention, this problem is solved by the fact that the shelf column is formed at least in part by at least one sheet metal bending part extending in the vertical direction of the shelf column.

[0005] Because the shelf column is formed, at least in part, by a sheet metal bending component, the shelf column, and thus the shelf upright, can be easily adapted to specific requirements. Sheet metal of varying thicknesses, readily available in a range of dimensions, can be used for the bending component. The dimensions of the bending component, and therefore of the shelf column, can be easily adjusted. Shelf columns with special shapes, particularly unusual cross-sectional forms, can be easily achieved by using a sheet metal bending component. Constructing a shelf column using at least one sheet metal bending component extending along the column's length thus enables cost-effective and / or material-saving production of a shelf upright that can be flexibly adapted to specific requirements.

[0006] The shelf column can be formed (or partially formed) by a sheet metal bending component with an open profile. The sheet metal bending component, viewed in cross-section perpendicular to the longitudinal direction of the shelf column, is open on at least one side. The shelf column formed by the sheet metal bending component can also have an open profile. A sheet metal bending component used for this purpose is preferably U- or C-shaped.

[0007] Preferably, the shelf upright has a hollow profile that is at least partially formed by the sheet metal bending part. The hollow profile is completely closed around its circumference in a cross-section transverse to the longitudinal direction of the hollow profile or the shelf upright. In particular, the hollow profile is formed from a sheet metal bending part or from two interconnected sheet metal bending parts. A hollow profile offers a favorable ratio of load-bearing capacity to material usage. By using a hollow profile, a more robust shelf upright can be obtained with the same amount of material. Alternatively, a shelf upright with the same load-bearing capacity can be obtained with less material. The hollow profile can have different cross-sectional shapes.

[0008] Particularly preferably, the hollow profile has a substantially rectangular outer circumference, in a section perpendicular to the longitudinal direction of the shelf column or the hollow profile, with two end faces and two long sides. A hollow profile designed in this way is suitable for easily replacing the square support tubes used previously. A substantially rectangular outer circumference is also achieved if additional elements, in particular grooves or projections, are formed into the end faces and / or the long sides, resulting in a local deviation from a strict rectangular shape. A square cross-section in which the end faces and the long sides are of equal length is also considered a rectangular cross-section.

[0009] Furthermore, it is particularly advantageous for the longitudinal sides to be longer than the end faces. This further improves the ratio of material usage to load-bearing capacity of the resulting shelf column. In particular, such a hollow profile is arranged on the shelf base in such a way that the long longitudinal sides extend parallel to the direction of the shelf base. A shelf column with such a rectangular cross-section can absorb the loads, especially bending moments, applied by support profiles arranged on the shelf column particularly well. Such a hollow profile exhibits a high section modulus and area moment of inertia.

[0010] Furthermore, and particularly preferably, the recesses are provided in one or both end faces of the rectangular hollow profile. A shelf upright in which the recesses are provided in only one of the two end faces is typically used as an L-shaped shelf upright, in which the support profiles can be hooked in from one side.

[0011] Alternatively, there are shelf uprights where support profiles can be attached to the shelf column from both sides. The shelf column and the shelf base typically form a T-shape together. This requires recesses to be cut into the two opposing ends of the rectangular hollow profile.

[0012] Alternatively or additionally, the recesses can be arranged in one or both of the long sides. Appropriately designed retaining elements can be inserted into the recesses in the long sides.

[0013] Preferably, the hollow profile is formed by exactly one sheet metal bending part. The sheet metal bending part extends around an interior area of ​​the hollow profile. The sheet metal bending part can be butt-welded.

[0014] This sheet metal bending part is particularly preferred in such a way that it extends more than 360 degrees around the interior of the hollow profile. Viewed in a cross-section perpendicular to the longitudinal direction of the hollow profile, this results in an overlap area of ​​the sheet metal bending part with itself.

[0015] The sheet metal part can be positively locked, force-locked, and / or, in particular, metallurgically locked to itself in this overlap area by suitable shaping, forming a hollow profile. A hollow profile made from exactly one sheet metal part can be manufactured easily. Viewed along its longitudinal direction, such a hollow profile has only one overlap or connection area. The hollow profile is therefore particularly stable.

[0016] Preferably, the single sheet metal bending part is designed such that it completely overlaps itself in the area of ​​one of the two narrow sides and / or in the area of ​​one of the two long sides, in which recesses for the retaining profiles are arranged. This overlap of the sheet metal bending part with itself doubles and reinforces this narrow side or long side. The hollow profile is particularly well suited to absorb loads applied via retaining profiles arranged in the recesses. If the wall thickness of the previously used square tubes was selected to be sufficient to absorb loads applied by retaining profiles in the area of ​​the recesses, a hollow profile formed by a correspondingly shaped bending part can be used with potentially thinner walls and thus with less material.The doubling of the material ensures that the required wall thickness is achieved only in the area of ​​the end faces where the recesses are located. The wall thickness in other areas of the hollow profile is reduced. This reduced material thickness results not only in cost savings but also in savings in resource consumption and the CO2 footprint of a corresponding shelf upright.

[0017] In an alternative preferred embodiment, the hollow profile is formed by two interconnected sheet metal bending parts, which are essentially U-shaped in cross-section. Essentially U-shaped sheet metal bending parts can also be referred to as essentially C-shaped sheet metal bending parts. These sheet metal bending parts have a base and legs arranged essentially perpendicular to the base. A sheet metal bending part is essentially C-shaped if it has a base and legs arranged approximately perpendicular to the base, regardless of whether further grooves or projections are formed in the base and / or the legs. Such U-shaped sheet metal bending parts can be bent particularly easily.

[0018] In particular, the hollow profile can be obtained by joining two identical sheet metal bending parts together. If identically shaped sheet metal bending parts are used, the effort required to manufacture the corresponding hollow profiles can be reduced.

[0019] The two sheet metal bending parts are arranged so that they overlap each other, at least partially, in the area of ​​their legs. A suitable design of the C-shaped sheet metal bending parts allows for a positive-locking and / or force-locking connection between the parts. Alternatively or additionally, the sheet metal bending parts can also be joined by a material bond, in particular by welding. This material bonding can be applied at specific points or throughout the entire joint.

[0020] The hollow profile is preferably formed by a first, U-shaped sheet metal part forming the two end faces, and a second sheet metal part having significantly shorter legs than the first. The sheet metal part forming the two end faces essentially forms three sides of the hollow profile, while the second sheet metal part with the significantly shorter legs closes the fourth side like a lid. The two sheet metal parts can be positively and / or force-fitted together by a suitable forming process. Alternatively or additionally, they can be material-fitted together.

[0021] When using two U-shaped sheet metal bending parts that overlap at their end faces, these can each overlap completely. This automatically reinforces the hollow profile at the end faces, where recesses for the retaining profiles are incorporated.

[0022] Preferably, an insert element reinforcing at least one end face is arranged, with corresponding recesses for retaining profiles being provided in this end face and in the insert element. The insert element can be attached to the hollow profile by frictional, positive, and / or material bonding. By using such an insert element, the hollow profile can be reinforced in the area of ​​the end face. The load-bearing capacity of the hollow profile can be increased simply and cost-effectively through this localized reinforcement. The wall thicknesses of the longitudinal sides can be reduced to suit the expected load case.

[0023] Alternatively or additionally, suitable insert elements can also be arranged on the long sides. This is particularly advantageous if the long sides are provided with recesses for attaching a retaining element.

[0024] Preferably, the hollow profile includes at least one retaining lug formed into one of its longitudinal sides adjacent to one of its end faces. Such a retaining lug provides a means by which the sheet metal part forming the hollow profile can be frictionally and / or positively locked to itself or to another sheet metal part forming the hollow profile. The sheet metal part can be clamped against itself or another sheet metal part in the area of ​​the retaining lug.

[0025] Preferably, the hollow profile comprises two retaining lugs formed adjacent to one of the end faces or one of the longitudinal sides, with one retaining lug being located in each of the two longitudinal sides or one of the two end faces of the hollow profile. This allows, firstly, the positive-locking and / or force-locking connection of the sheet metal part(s) to itself or to each other, provided the sheet metal part(s) are suitably designed. Secondly, this allows for a symmetrical and therefore visually appealing appearance of the shelf upright.

[0026] The hollow profile preferably features four retaining lugs, two pairs of which are arranged adjacent to the end faces on the long sides, or adjacent to the long sides on the end faces. This further improves the visual appearance of the shelf upright.

[0027] Alternatively or additionally, retaining lugs can be used to secure insert elements that locally reinforce the hollow profile in the area of ​​the end faces or longitudinal sides where the recesses for the retaining profiles are located, either by friction or form-fitting. For this purpose, an insert element can be inserted or pressed between a retaining lug and the end face or longitudinal side adjacent to the retaining lug. A connection can be formed by pressing the insert element in or as a result of slight deformation of the hollow profile or the retaining lug when the shelf upright is subjected to a load during use.

[0028] In the same way, the retaining lugs can be used to easily fix profile rails, especially those designed as top-hat rails, to the hollow profile in a force-fit and / or form-fit manner.

[0029] Preferably, the hollow profile has a longitudinal groove extending along the shelf upright on at least one of its two long sides, and more preferably on both long sides. Because the shelf upright is formed from a bent sheet metal part, such a longitudinal groove can be obtained in one or both of the long sides in a particularly simple and cost-effective manner. Such a longitudinal groove can be used to attach further elements to a cantilever rack constructed with corresponding uprights. These elements could, for example, be back panels to be positioned between two adjacent uprights. These can simply be inserted into corresponding longitudinal grooves in the respective uprights. The grooves can also be used to attach other components to the upright.In particular, two adjacent shelf uprights can be connected to each other via cross braces arranged in the respective grooves. This allows the center-to-center spacing of the shelf to be easily determined.

[0030] The groove is typically U-, V-, or T-shaped. Particularly when the groove is T-shaped, additional components can be easily screwed to the shelf upright or the long side of the shelf column using T-nuts positioned within the T-slot. Such a shelf upright offers exceptional versatility.

[0031] Preferably, the shelf upright comprises at least one profile rail arranged on the sheet metal component, extending longitudinally along at least a section of the shelf upright. The use of such profile rails allows for a further reduction in the material thickness of the sheet metal component. The section modulus and area moment of inertia of the shelf upright can be increased by attaching a corresponding profile rail to the sheet metal component. Adapting the shelf upright to different load cases therefore does not necessarily require the use of different sheet metal components with varying dimensions and / or material thicknesses. Instead, a standard sheet metal component can be used, which is adapted to the expected load case by attaching one or more profile rails.Adaptation can also be achieved by providing different profile rails with different dimensions, from which a suitable one is selected depending on the expected load on the shelf upright and arranged on the sheet metal bending part.

[0032] The profile rail can, in particular, be arranged extending along the entire longitudinal extent of the shelf column or the sheet metal bent part.

[0033] Preferably, the profile rail extends only along a portion of the sheet metal bending component. Specifically, this is a section extending upwards from the shelf base. The upright of a cantilever rack is subjected to bending moments by the loads placed on the support profiles forming the cantilevers. These moments are greatest in the area where the upright is fixed to the shelf base and decrease vertically upwards. Typically, the uprights are designed to absorb the bending moments in the area of ​​the shelf base and extend upwards with this cross-section along their longitudinal direction. The upright is thus significantly over-dimensioned in the area furthest from the shelf base. A profile rail arranged on the sheet metal bending component can selectively increase the section modulus and area moment of inertia of the upright in the lower area, near the shelf base.The cross-section of the shelf upright can be adapted to the expected load cases, particularly the anticipated bending moment distribution. The profile rail only needs to be positioned in a lower section of the sheet metal component, where the highest bending moments are expected. The sheet metal component is reinforced at specific points by the profile rail. This allows for more targeted material usage in the shelf upright, resulting in overall material savings. The cost of such a shelf upright is lower. The shelf upright requires less material and has a lower carbon footprint.

[0034] In particular, the amount of material used can be even better adapted to the bending moment distribution by using different profile rails. For example, two or more profile rails can be used in the lower section of the shelf column, arranged side by side, one behind the other, and / or nested within each other.

[0035] The profile rails are of varying lengths, so the shelf column is reinforced by several profile rails in its lower section. The reinforcement by profile rails decreases progressively towards the end of the shelf column opposite the shelf base. Specifically, the shelf column comprises at least two profile rails that enclose different cross-sectional areas in a cross-section perpendicular to the longitudinal direction of the shelf column. The end of a profile rail enclosing a smaller cross-sectional area, facing away from the shelf base, is positioned further away from the shelf base in the longitudinal direction of the shelf column than the end of a profile rail enclosing a larger cross-sectional area. The shelf column is progressively reinforced by the profile rails towards the shelf base. Conversely, the amount of material used decreases upwards in the longitudinal direction from the shelf base.In this way, a shelf upright can be provided which is adapted to the expected load case, in particular the expected bending moment distribution, along the longitudinal extension direction of the shelf column.

[0036] Preferably, the profile rails are arranged one inside the other and / or one behind the other in the longitudinal direction of the shelf column.

[0037] The profile rails can be arranged on the sheet metal part in a form-fit, force-fit, and / or material-fit manner. In particular, the profile rails are spot-welded or continuously welded to the sheet metal part.

[0038] If the shelf column has an open profile, the profile rail(s) can be easily attached to the sheet metal part. In particular, a profile rail can be easily welded to a sheet metal part with an open profile.

[0039] The profile rails can also be used when the shelf column is formed by a hollow profile, which in turn is formed by at least one bent sheet metal part. Preferably, the profile rail(s) are then arranged inside the hollow profile.

[0040] The profile rail(s) are preferably arranged on one of the longitudinal sides of the hollow profile. This is particularly advantageous in conjunction with a hollow profile formed by U-shaped sheet metal bending parts. The profile rails can then be arranged on a base section of one of the U-shaped sheet metal bending parts before the hollow profile is assembled, and in particular, welded to it. After the two U-shaped sheet metal bending parts are joined, this base section forms one longitudinal side of the hollow profile. Such a hollow profile can be easily produced.

[0041] In particular, the profile rail is also U-shaped for this purpose. Preferably, such a profile rail is fixed to the sheet metal part in such a way that the profile rail and the sheet metal part form a closed circumference. The profile rail can also be designed as a double-T rail. Such a double-T rail is preferably arranged analogously to a U-shaped profile rail. The double-T rail forms a closed circumference with the sheet metal part. The legs of the T-shaped sections project rearward from the part of the sheet metal part to which the profile rail is fixed.

[0042] In an alternative preferred embodiment, the shelf column comprises at least two profile rails, each arranged on the opposite end faces of the hollow profile. In particular, the opposing profile rails are of the same design.

[0043] In this case, the profile rails are preferably designed as top-hat rails. The opening of these top-hat rails faces the end faces, such that the top-hat rails do not obstruct the insertion of retaining elements into any recesses arranged in the end faces.

[0044] Particularly preferred are the profile rails arranged in the hollow profile in a form-fit and / or force-fit manner. For this purpose, the hollow profile can have retaining lugs formed into its longitudinal sides adjacent to the end faces. A profile rail designed as a top-hat rail can then be inserted or pressed into the hollow profile between the end face and the retaining lugs along its longitudinal direction. This creates a form-fit and / or force-fit connection. The form-fit and / or force-fit connection can be established as soon as the profile rails are inserted into the hollow profile. Alternatively, the force-fit and / or form-fit connection can also be created as a result of slight deformations of the sheet metal part(s) that occur when such a shelf upright is first subjected to a sufficiently large load.

[0045] In this case, it is particularly preferred that at least two different DIN rails of different depths are used, arranged one behind the other in the hollow profile forming the shelf column. First, the shallower of the two hollow rails is inserted or pressed into the hollow profile from below. Then, a deeper profile rail is pushed in, thereby advancing the smaller profile rail further along its longitudinal direction.

[0046] This is particularly preferred on both ends. This allows for the simple production of a shelf column for a shelf upright, which is adapted to the expected load case, especially the expected bending moment distribution, in a material-saving manner.

[0047] In the recesses for inserting retaining elements, further recesses may be arranged on the shelf upright, in particular on the shelf columns of the shelf upright, via which any attachment parts can be fixed to the shelf column of the shelf upright.

[0049] Parts with identical or similar effects are provided with identical reference numerals, where appropriate. Individual technical features of the embodiments described below can be combined with the features of claim 1 and with the features of individual embodiments described above to form articles according to the invention.

[0050] Fig. Figure 1 shows an L-shaped shelf upright 2 with a shelf base 4 and a shelf column 6. The shelf column 6 is arranged on the shelf base 4 such that it extends vertically in its operating position. The shelf column 6 is designed as a hollow profile 8 with a substantially rectangular cross-section. This cross-section is obtained by taking a section perpendicular to the longitudinal direction L of the shelf column 6. The hollow profile 8 has end faces 10 and long sides 12. The end faces 10 are shorter than the long sides 12. Recesses 14 are provided in at least one of the end faces 10. The recesses 14 are designed to accommodate support profiles, allowing the illustrated shelf upright 2 to be combined with other identically or similarly designed shelf uprights to form a cantilever rack.

[0051] Fig. Figure 2 shows a shelf upright 2 in an alternative embodiment. The shelf upright 2 is T-shaped. Recesses 14 are arranged on both end faces 10 of the shelf column 6. A shelf constructed with this shelf upright 2 can be fitted with retaining profiles on both sides and loaded from both sides.

[0052] Fig. Figure 3 shows a section of shelf column 6. Shelf column 6 according to Fig. 3 is both for the shelf stand according to Fig. 1 as well as for shelf stand 2 according to Fig. 2. The shelf column 6 is formed from a single sheet metal bending part 16. This forms a hollow profile 8. For this purpose, the sheet metal bending part 16 is bent so that it extends completely around an interior space of the hollow profile 8. The sheet metal bending part 16 forms a hollow profile 8 that has a substantially rectangular cross-section, with longitudinal sides 12 and end faces 10. Recesses 14 are provided in the end faces 10. The sheet metal bending part is designed so that in the area of ​​the Fig. The front end face 10 is doubled. The recesses 14 extend through both layers of the sheet metal bending part 16. The hollow profile 8 formed from the sheet metal bending part 16 is thereby reinforced in the area of ​​the end face 10 with the recesses 14.

[0053] The sheet metal part 16 has a longitudinal groove 18 in the center of each of its longitudinal sides 12. The longitudinal sides 12 are also provided with retaining lugs 20 adjacent to the respective end faces 10. These are formed into the sheet metal part 16. The retaining lugs 20 in the area of ​​the Fig. The three front end faces 10 serve to secure the sheet metal bending part 16 to itself in a form-fitting and / or force-fitting manner, so that it can form the hollow profile 8. The sheet metal bending part 16 can also be bonded to itself, in particular by welding. The retaining lugs 20 on the opposite sides of the longitudinal sides 12 adjacent to the opposite end face 10 primarily serve to achieve a visually appealing appearance of the hollow profile 8 and thus of the shelf column 6.

[0054] The retaining lugs 20 can also be used to secure back panel elements. For this purpose, back panel elements can be inserted, in particular slid, into a retaining lug 20 of the shelf upright 2 as well as into a retaining lug 20 of an adjacent shelf upright 2. Back panel elements made of cardboard, in particular, can thus be secured via the retaining lugs 20.

[0055] Fig. Figure 4 shows a top view of the shelf upright 2 with the shelf foot 4 and the shelf column 6 attached to it. The shelf column 6 is formed by the hollow profile 8, which is formed by the sheet metal bending part 16. The longitudinal grooves 18 in the two longitudinal sides 12 and the retaining lugs 20, which are arranged adjacent to the end faces 10 in the longitudinal sides 12, are visible.

[0056] Fig. Figure 5 shows a shelf upright 2 in a top view, where the shelf upright 2 is T-shaped. Such a T-shaped shelf upright 2 serves to form cantilever racks that can be loaded from both sides. The shelf upright 6 is provided on both end faces 10 with recesses 14 into which retaining profiles can be inserted. The in Fig. The lower end face 10 is reinforced by the double-layered sheet metal bending element 16 in this area. The opposite end face 10 is reinforced by an insert element 22. This insert element can be arranged on the sheet metal bending element 16 in a form-fit, force-fit, and / or material-fit manner.

[0057] The insert element 22 is arranged inside the hollow profile 8. The insert element 22 is provided with recesses corresponding to the recesses 14.

[0058] Fig. Figure 6 shows a top view of a shelf column 6 of a shelf upright 2 in a third embodiment. The shelf column 6 is again formed by a hollow profile 8, which is formed by a sheet metal bending part 16. The sheet metal bending part 16 is again formed with longitudinal grooves 18 in the longitudinal sides 12 and with retaining lugs 20 in the longitudinal sides 12. The overlap of the sheet metal bending part 16 with itself is significantly reduced. It only occurs in the area of ​​one of the retaining lugs 20. Profile rails 24 are inserted into the hollow profile 16. In the illustrated embodiment, the profile rails 24 are designed as top-hat rails. These are each arranged on the end faces 10 such that their openings are adjacent to the recesses 14 in the end face 10. The profile rails 24, designed as top-hat rails, thus leave the recesses 14 free, so that retaining profiles can still be arranged in the recesses 14. In the embodiment shown Fig. In the embodiment shown in Figure 6, two identical DIN rails are arranged as profile rails 24, extending along the entire longitudinal direction of the shelf column through the hollow profile 8. By using appropriate profile rails 24, the hollow profile 8 formed by the sheet metal bending part 16 can be easily adapted to different load cases. The profile rails 24, designed as DIN rails, are connected to the sheet metal bending part 16 in the area of ​​the retaining lugs 20. In this way, the profile rails 24 can be fixed in the hollow profile 8 by positive locking and / or friction locking. The profile rails 24 can be pressed into the hollow profile 8 from above or from below in the longitudinal direction.

[0059] Fig. Figure 7 shows a top view of shelf stand 2 with the according to Fig. 6 trained shelf columns 6.

[0060] Fig. Figure 8 shows the upper end of a shelf column 6 in a fourth embodiment. No profile rails 24 are visible in the illustrated view of the upper end of the shelf column 6. The hollow profile 8 corresponds to the hollow profile 8 as also used in the shelf columns according to [reference to relevant figure]. Fig. 6 and Fig. 7 is used.

[0061] The difference to this embodiment is in Fig. 9 to recognize a view of a shelf stand 2 with a shelf column 6 according to Fig. Figure 8 shows that the shelf column 6, in addition to the hollow profile 8 formed by the sheet metal bending part 16, also includes profile rails 24. In the exemplary embodiment, two profile rails 24 are arranged on each of the two end faces 10. The profile rails 24 are designed as top-hat rails with different depths. The deeper of the two profile rails 24 is arranged on the end of the shelf column 6 facing the shelf foot 4. The second profile rail 24 is arranged above the first profile rail 24 and is shallower. No profile rail is arranged above the second profile rail 24, as shown in Figure 8. Fig. Figure 8 illustrates this. The use of several profile rails 24, which are designed differently and, in particular, do not extend along the entire longitudinal direction of the shelf column 6, allows for easy adaptation of the shelf column 6 to the expected load case. The section and area moments of inertia of the shelf column 6 can be easily adapted to the expected load case, especially the expected bending moment distribution, by using the profile rails 24.

[0062] The different sections in which the profile rails 24 are arranged are in Fig. 10 recognizable. Fig. Figure 10 is a cross-section through a corresponding shelf upright 2. It can be seen that no profile rail 24 is arranged on the upper third of the shelf upright 6. In the middle third, two opposing profile rails 24 are arranged, which have a shorter extension along the longitudinal sides 12 compared to the profile rails 24 arranged in the lower third. The profile rails 24 are also shallower. Such a shelf upright can be adapted to expected load cases particularly easily and with minimal material usage.

[0063] Fig. Figure 11 shows a comparable cross-section through a T-shaped shelf upright 2.

[0064] Fig. Figure 12 shows again the resulting cross-sections perpendicular to the longitudinal direction of the shelf column 6 in an upper third, a middle third and a lower third of the shelf column 6.

[0065] Fig. 13, Fig. 14, Fig. 15 to Fig. Figure 16 shows a further embodiment with profile rails 24 of different depths. The profile rails 24 are formed as sheet metal folded in a T-shape. In this embodiment, corresponding recesses are arranged in the profile rails 24 to the recesses 14. The profile rails 24 thus cause the end faces 10 to be doubled. A separate insert element 22 is not required.

[0066] In the exemplary embodiment, three different profile rails 24 with different depths are arranged one behind the other in the longitudinal direction L of the shelf column 6, as shown in Fig. 16 to recognize.

[0067] The profile rails 24 of this embodiment can be fixed in the hollow profile 8 via retaining lugs 20.

[0068] For the design as an L-shaped shelf upright 2, the use of profile rails only on the front end face 10 may be sufficient.

[0069] Fig. 17 and Fig.Figure 18 shows views of another shelf column 6. In this shelf column 6, the hollow profile 8 is formed by two sheet metal bending parts 16.1 and 16.2. One of the two sheet metal bending parts 16.1 forms a longitudinal side 12 and the two end faces 10. The recesses 14 are arranged in the end faces 10. This sheet metal bending part 16.1 is U-shaped or C-shaped. The opposite longitudinal side 12 is formed by another sheet metal bending part 16.2. This sheet metal bending part 16.2 can also be described as U-shaped. However, the legs of the U are significantly shortened. It can be seen that the sheet metal bending part 16.1 forming the end faces 10 is shaped in the end region of the end faces 10 in such a way that the other sheet metal bending part 16.2 can be correspondingly and positively locked to it. The sheet metal bending part 16.2 forming the other longitudinal side 12 forms a lid.Furthermore, it can be seen that in this case two profile rails are arranged, which are designed as U-profiles. The two profile rails 24 have different dimensions. They are arranged nested inside one another on one of the two longitudinal sides 12. The profile rails 24 can be easily arranged on the longitudinal sides 12 of the sheet metal bending part 16.1 before this is completed with the sheet metal bending part 16.2 to form a hollow profile 8. A shelf upright 2 with a corresponding shelf column 6 can thus be obtained in a particularly simple way. By appropriately selecting the dimensions, number, and arrangement of the profile rails 24, the shelf column 6 can be easily adapted to the expected load case, in particular to an expected bending moment distribution.
