Description

[0001] The present invention relates to a stanchion for a vehicle body with at least one loading level, in particular a double-decker semi-trailer, with a stanchion base body and at least one holding and guiding device for a load securing device according to the preamble of claim 1, a stanchion system comprising the stanchion according to the invention according to the preamble of claim 11, a commercial vehicle body, in particular a trailer body or semi-trailer body, with at least the stanchion according to the invention and / or the stanchion system according to the invention according to claim 12, and a commercial vehicle with the commercial vehicle body according to the invention, the stanchion system according to the invention and / or the stanchion according to the invention according to claim 13.

[0002] EP 3 127 789 A2 already discloses a stanchion for a commercial vehicle body, in particular a semi-trailer, comprising a stanchion base body and at least one holding and guiding device for a load securing device. The holding and guiding device is firmly connected to the stanchion base body and has two profile legs arranged essentially parallel to one another. Furthermore, the holding and guiding device has a plurality of receiving means for at least one fixing device of a load securing device. The receiving means are arranged at different heights of the holding and guiding device.The known stanchion differs from other known stanchions in that the holding and guiding device itself has multiple receiving means, so that a fixing device of a load securing device can be arranged at different heights of the holding and guiding device, in particular at different heights of the stanchion. This allows for flexible use of the load securing device. The stanchion base body is preferably formed from a profile with a low wall thickness, unchanged over its entire length, with the holding devices being an integral part of the stanchion base body.

[0003] However, the roll forming or roll forming of the stanchion base body with holding device as an integral component from only one sheet metal part known from EP 3 127 789 A2 can only be carried out with a relatively small wall thickness of the sheet metal part as intended in 180° forming, which means that the known stanchion cannot be used, for example, for vehicle bodies with more than one loading level. Disclosure of the invention

[0004] The object of the invention is to at least partially improve the stanchion with holding device known from the prior art. In particular, the object of the present invention is to design a stanchion with holding and guiding device with sufficient material thickness for multi-decker bodies, for example, wherein the forming of a material part, in particular a metal strip or sheet metal strip, into the stanchion can advantageously be carried out in a roll-forming or rolling process. Furthermore, the object of the present invention is to create an additional loading level with a simple adjustment device that is lightweight compared to known multi-decker bodies. Finally, the object of the present invention is to create a commercial vehicle with a multi-decker body, in particular a double-decker body.

[0005] The above object is achieved by a stanchion for a vehicle body with at least one loading level having the features of claim 1, by a stanchion system with the stanchion according to the invention having the features of claim 11, by a commercial vehicle body with at least two loading levels having the features of claim 12 and by a commercial vehicle with the commercial vehicle body according to the invention, the stanchion system according to the invention and / or the stanchion according to the invention, having the features of claim 13.

[0006] Further advantages, features and details which may be essential to the invention emerge from the subclaims, the description and the drawings.

[0007] The stanchion according to the invention for a vehicle body with at least one loading level, in particular a semi-trailer with a double deck, with a stanchion base body and at least one holding and guiding device for a load securing device includes the technical teaching that the stanchion base body comprises, at least in sections, a formation on at least one longitudinal side, via which the holding and guiding device can be connected to the stanchion base body at least in a form-fitting and / or material-fitting manner.

[0008] The stanchion according to the invention differs from the previously known prior art in that the holding and guiding device represents a separate component from the stanchion base body, wherein the stanchion base body can be produced from a material with a large wall thickness and the holding and guiding device from a material with a small wall thickness separately from one another in a roll forming or rolling process or as an extruded profile with advantageously the same wall thickness, in order to then be able to connect them to one another at least positively and / or materially via the formations formed on the stanchion base body on its long side.

[0009] Advantageously, the holding and guiding device can be connected to the stanchion base body via the formations, at least positively and / or materially, over the entire length, i.e. over the entire long side of the stanchion base body, which is formed by the formations configured over the entire length of the stanchion base body. A materially bonded connection is advantageously understood to mean an adhesive bond between the stanchion base body and the holding and guiding device. Compared to a welded connection, which can also be considered in principle for the production of the stanchion according to the invention in order to materially connect the holding and guiding device to the stanchion base body, an adhesive bond does not require the temperatures required for the welded connection, which lead to warping of the materials. In addition, the adhesive bond between the components is suitable for being able to be removed again if necessary.A further advantage of an adhesive connection over a welded connection is that all surfaces of the components to be bonded together can already be finished, for example, painted, galvanized, or powder-coated. This eliminates the need for subsequent surface finishing of the bonded components, unlike components bonded together by welding. The design of the holding and guiding device across the entire length of the stanchion increases its flexibility when used with a load securing device, as the entire length of the stanchion base body can be used to flexibly position a fastening or fixing element of a load securing device.However, the holding and guiding device can also be connected to the pillar base body over at least half or at least two-thirds of the length of the pillar base body and extend over only the aforementioned reduced length. Alternatively, the holding and guiding device can be attached to the pillar base body, for example, by riveting.

[0010] However, it is advantageous that the stanchion base body has a formation on at least one longitudinal side, which, as a common component with the stanchion base body, is formed in a roll forming or rolling process from a material strand, for example from a flat iron or a flat steel, in one piece from the material strand with the same wall thickness into the profile shape of the stanchion base body with the at least one formation.The one-piece roll forming of the stanchion base body with one or two formations from a material strand simplifies the manufacturing process in that only one joining connection is required, with which the end faces of the material strand, which are free to meet one another after the forming process, must be joined together in a material-locking manner, for example by adhesive bonding or by a welding process, such as laser welding, in order to produce a closed component that meets the requirements for the stability to be guaranteed for the stanchion base body.

[0011] It is also conceivable to design the stanchion base body with at least one formation as a double shell, in which case, however, at least two joints would have to be connected to one another using the methods mentioned above.

[0012] Furthermore, it is conceivable that the stanchion base body and the formation or formations are manufactured as separate components which can be connected to one another using a joining process mentioned above or otherwise, for example by screwing or riveting.

[0013] Regardless of whether the protrusion(s) are integrally formed with the pillar base body or are attached or connected to the pillar base body as separate components, the protrusion advantageously has a cross-section that is smaller than the pillar base profile. Particularly preferably, the cross-section of the protrusion is smaller than the pillar base body by twice the wall thickness of the pillar base body.This means that with a wall thickness of the stanchion base body of, for example, 3 mm, the cross section of the formation is reduced by 6 mm compared to the cross section of the stanchion base body. This design has the advantage that with the positive and / or material-locking connection of the holding and guiding device via the formation with the stanchion base body, whereby the holding and guiding device advantageously has the same wall thickness as the stanchion base body, the stanchion base body and the holding and guiding device abut or lie flat against one another.

[0014] To increase the strength of the connection between the holding and guiding device and the stanchion base body via the recess, the recess advantageously has a dovetail-shaped cross-section orthogonal to its longitudinal extent, with the dovetail-shaped cross-section widening from the stanchion base body to the outside of the recess. This design enables a positive connection between the recess and the associated holding and guiding device, whereby this connection can withstand tensile loads. Instead of the dovetail-shaped cross-section of the recess, other shapes or joints can also be designed that are tensile load-bearing.

[0015] A "stanchion" is preferably understood to mean a suspension stanchion that advantageously comprises a roller arrangement or sliding device on its upper side, with the aid of which the stanchion can be displaced laterally on a rail arranged above the side edge of a vehicle. Within the meaning of the present invention, "stanchions" are understood to mean center stanchions and corner stanchions of a vehicle body. If the stanchion according to the invention is designed as a corner stanchion, it advantageously has a recess on only one longitudinal side for at least a positive and / or material-fit connection to a holding and guiding device.

[0016] The stanchion according to the invention can be provided as a corner stanchion or as a center stanchion on a commercial vehicle body. Advantageously, the stanchion base body has a guide rail for a sliding element. The sliding element allows the stanchion, which is usually arranged between a loading floor and a roof of a commercial vehicle body, to be unhooked from the loading floor or lower frame part of the commercial vehicle body and moved along the commercial vehicle body or completely removed from the commercial vehicle body. This is advantageous in order to use the entire width of a commercial vehicle body for lateral loading and unloading. However, it is not excluded that a stanchion designed as a corner stanchion also has a sliding element that is arranged in a guide rail of the stanchion base body.When using the stanchion according to the invention in a commercial vehicle body constructed as a multi-decker, in particular a double-decker, as described in DE 10 2023 107 596 B3 by the applicant of the present invention, the load securing devices in the form of longitudinal beams can be guided independently of one another and relative to one another in the vertical direction between the stanchions or the holding and guiding devices designed as profiles, which should also apply to the stanchion according to the invention of the present invention. Due to the independent guidance of the mutually parallel longitudinal beams, the cross beams connected to the longitudinal beams can advantageously be guided from a horizontal position to an inclined position and back.Preferably, two longitudinal beams lying parallel to one another between two stanchions in the longitudinal extension of the vehicle body, with the stanchions lying orthogonally thereto, form a loading field which can be converted into an inclined position and back again by the independent guidance of the longitudinal beams lying parallel to one another. This preferably follows that during side loading or unloading, which takes place with the tarpaulin open, the loading level above can advantageously be converted into an inclined position for loading or unloading the lower loading level, for example in order to unload the goods transported on the lower loading level from the vehicle using a forklift truck. Preferably, the upper second loading level can be converted into an inclined position from the horizontal of 5° to 20° due to the telescopic longitudinal beams according to the invention.Particularly preferably, the inventive guidance of the two longitudinal beams from one another and relative to one another in the vertical direction between the stanchions or the profiles allows an inclination of the cross beams connected to the longitudinal beams or an inclination of the loading field formed thereby from the horizontal of 15°. It is also advantageous that the longitudinal beams guided between the stanchions or the profiles can be converted from their parallel position to the longitudinal extent of the vehicle body into an inclined position to the longitudinal extent of the vehicle body and back again. Firstly, this advantageous embodiment allows the loading field of the second loading level formed from the longitudinal beams and the cross beams connected thereto to be lifted on at least one side, namely in the region of the guide in a stanchion, for example in order to remove a load transported on the first loading level.Secondly, the transfer of the longitudinal beams guided in the holding and guiding device designed as profiles from the horizontal, which lies parallel to the longitudinal extent of the vehicle body, into an inclined position allows the height positioning of the second loading level between the first loading level and the vehicle roof to be carried out step by step, whereby first the longitudinal beam is pushed up or down on one stanchion and subsequently the longitudinal beam on the other stanchion is pushed up or down. These steps can be carried out and repeated with little effort, thus enabling one-person operation in order to be able to move the second loading level relative to the first loading level. In general, the technical implementations known from DE 10 2023 107 596 B3 and described here should also apply to the use of the stanchion according to the invention in a vehicle body, in particular a multi-level body.

[0017] Particularly when using the stanchion as a center stanchion, it is preferred if the stanchion has two protrusions formed on opposite sides of the stanchion base body, in order to be able to connect a holding and guiding device on the opposite sides of the stanchion base body to the stanchion base body via each of the protrusions, at least in a form-fitting and / or material-fitting manner. In this way, load securing devices can be attached to both sides of the stanchion. Typically, the load securing devices extend between two stanchions in the assembled state, which can be two center stanchions or a corner stanchion and a center stanchion.

[0018] Preferably, the holding and guiding devices are essentially identical in design, but they can also be designed differently depending on the intended use, for example for individual loading fields of a loading level.

[0019] Load securing slats can be provided as load securing devices. These are positioned between two stanchions in the guide of the holding and guiding device and placed in receiving means for reaching through and receiving a fastening or fixing element, in particular a slider with hooks, which serves to fasten and fix the load securing device to the stanchion. Alternatively, it is possible to fix a rail with a hole pattern, for example a keyhole pattern, in the holding and guiding device. The rail can accommodate one or more insert rods. Other load securing devices include nets or grid elements, which can be easily and quickly positioned and / or replaced thanks to the flexible height division in the holding and guiding device.To guide the load securing device in the form of longitudinal slats or longitudinal beams vertically to the first load level, the stanchions designed as stanchion profiles or the profiles preferably have an architecture that allows the longitudinal beams to be guided along the stanchions. It is also conceivable for the longitudinal beams to encompass the stanchions or profiles at least in sections in order to be guided along the stanchions. Particularly preferably, guide grooves or guide rails are formed in the stanchions or profiles or arranged on the stanchions or profiles, which allow the longitudinal beams to be guided.

[0020] It is advantageous to provide receiving means for securing the longitudinal beams at different heights in the holding and guiding devices and, congruently, in the recesses of the stanchion body at predetermined locking positions. The receiving means are advantageously uniformly spaced along the length of the stanchion to create load heights that are preset, for example, to the height of transport baskets. The predetermined positions allow the driver or another person to adjust the height of the second loading level relative to the first loading level without repeated testing, for example, to be able to load both the lower and upper loading levels with transport baskets or other prefabricated cargo.

[0021] For at least force- and / or form-fitting engagement in the receiving means designed at the locking positions or for receiving locking elements at the locking positions, locking elements are advantageously designed at both ends of the load securing device, for example in the form of longitudinal bars.The locking elements advantageously interact with the receiving means at the locking positions in such a way that they either engage therein, for example in the form of recesses, grooves, or slots of the receiving means in the region of the locking positions, into which at least one latch in the form of a ratchet latch or a hook, configured at both ends of the longitudinal beams, engages, or the stanchions themselves have locking elements at the locking positions, for example in the form of latches, which engage in receiving means configured in the form of grooves or slots in the longitudinal beams at both ends thereof, so that the longitudinal beams can be releasably held and advantageously locked in the locking positions at a height determined by the locking positions. The locking positions can advantageously be selectively opened manually or with machine assistance.

[0022] Preferably, in the region of the locking positions, the receiving means are designed as recesses in the form of bores, punched outs, or milled recesses in the formations and / or in the holding and guiding devices. After the positive and / or material connection between the stanchion base body and the holding and guiding device, the receiving means in the formations and in the associated holding and guiding devices are designed to lie congruently one above the other, i.e., they are aligned with one another. The receiving means of the holding and guiding device and the receiving means in the formations are advantageously provided in pairs along the longitudinal extension of the stanchion at different height positions.Advantageously, the receiving means completely penetrate the formations, which has the advantage that, for example, a hook designed on the load securing device can, on the one hand, engage into the stanchion base body to a certain depth and, on the other hand, the hook rests with its underside on an advantageously double wall thickness, namely both on the wall of the formation and on the wall of the holding and guiding device in the area of ​​the receiving means.If, for example, the stanchion base body is formed with a wall thickness of 3 mm and the holding and guiding device also has a wall thickness of 3 mm, the load securing device with the hook configured thereon rests on a total wall surface of 6 mm, thereby increasing the stability between the stanchion and the load securing device and the overall stability of a vehicle body. This means that, among other things, the stability requirements of a double-decker or multi-decker body can be met. In addition to the design in which the receiving means in the form of recesses completely penetrate the formations of the stanchion base body, depressions are also conceivable, or a combination of these two designs. In the design as depressions, the recesses are formed in the stanchion base body with the formation so that the fixing device can be inserted into them safely and stably.

[0023] The receiving means can also be designed as webs or similar support elements that are formed at different height positions in or on the holding and guiding device.

[0024] In an advantageous embodiment, the holding and guiding device is designed approximately in the shape of a double-T profile, whereby the holding and guiding device comprises, orthogonally to its longitudinal extent, a U-profile with a cross-section and a C-profile with a cross-section, wherein the web of the double-T profile forms the adjacent base surfaces of the U-profile and the C-profile, of which two profile legs for each of the profiles extend in opposite directions. The two profile legs of the U-profile, which are aligned with the shape of the stanchion base body, serve to overlap the shape and to form a positive and / or material-fit connection between the holding and guiding device and the stanchion base body.In order to create a tensile-resistant connection between the stanchion base body and the holding and guiding device when the cross-section of the protrusions is designed as a prong connection, particularly in the shape of a dovetail, the profile legs are at least slightly bent inward toward the base body. The C-profile, whose profile legs are designed in the opposite direction to the profile legs of the U-profile, is advantageously bent inward at its end face such that the free ends, namely the end faces of the profile legs, face toward each other. In this way, the C-profile is designed as a guide rail for the load securing device.

[0025] Preferably, the holding and guiding device is formed from a material strand, in particular a flat iron or flat steel, in one piece in the shape of a double-T profile. In contrast to the material thickness of the material strand from which the stanchion base body and the molding are formed, the material strand to be formed for the holding and guiding device has a thinner wall thickness, which allows the material to be doubled up to a bend of 180° to form the aforementioned double-T profile without the material breaking during forming.However, the described geometric shapes of the double-T profile can only be implemented in a roll forming process from a very small wall thickness of less than 1 mm up to a maximum wall thickness of between 1.4 mm and 1.8 mm, which is also the reason, among other things, why the stanchion base body of the stanchion according to the invention with a wall thickness of 2.2 mm to 3.6 mm is manufactured as a component separate from the holding and guiding device in a roll forming or rolling process.In order to obtain a wall thickness for the holding and guiding device after the roll forming or rolling process which corresponds to the wall thickness of the stanchion base body, the starting material used for the holding and guiding device advantageously has a wall thickness which corresponds to half the wall thickness of the starting material for forming the stanchion base body and the shaping, so that after forming the wall thickness of the double-T profile is equal to the wall thickness of the stanchion base body with the shaping.

[0026] A further aspect of the invention is a stanchion system with the stanchion according to the invention. In order to be able to change the overall height of a vehicle body as needed, the stanchion base body and the at least one formation are formed from at least two profiles that can be moved relative to one another, wherein the profiles interlock in such a way that they serve mutually as rail guides and / or support one another in adjustable and / or limited lengths of the stanchion base body and the at least one formation. Advantageously, the profiles are guided into one another in the form of insert elements in such a way that they mutually serve as rail guides and thus the overall base body of the stanchion can be shortened or lengthened relative to one another by pulling the profiles together or apart, namely is in particular telescopic.In a particularly advantageous manner, the profiles support each other in adjustable lengths of the base body, or have stop points that prevent a shortening or lengthening of the base body beyond a certain length or that allow an adjustment of the length of the base body in predetermined positions.

[0027] In a particularly preferred manner, the stanchion system can be formed from modular units, which can considerably simplify the assembly effort, since the modular units can be delivered or ordered pre-assembled.

[0028] In order to avoid repetitions regarding the advantages of the stanchion system according to the invention, reference is made to the description of the advantageous embodiments of the stanchion according to the invention and the disclosure by this description is fully incorporated and vice versa.

[0029] An additional aspect of the present invention is a commercial vehicle body with at least one loading level, in particular a trailer body or semi-trailer body, with the stanchion according to the invention and / or the stanchion system according to the invention.

[0030] The commercial vehicle body according to the invention is advantageously designed as a double-decker or multi-decker body, which, by using the stanchion according to the invention and / or the stanchion system according to the invention, provides an excellent opportunity to significantly increase the economic efficiency of the commercial vehicle due to the additional loading level formed, since with each additional loading level, 33 additional loaded or packed Euro pallets can be transported, which means that with a second loading level, i.e. a double-decker body, instead of 33 loaded or packed Euro pallets, 66 loaded or packed Euro pallets can then be transported simultaneously.When loading the commercial vehicle with loaded or packed, preferably foldable, pallet cages, these can advantageously be folded after unloading on the return journey and transported in a folded state either on the upper, second, or lower loading level. In this case, either the free loading level is available for the transport of, for example, 33 loaded or packed Euro pallets, or, with pallet cages packed in a folded state on Euro pallets, both loading levels are available for the transport of a total of 66 Euro pallets. Due to the wall thickness of at least 3 mm of the stanchion base body and the overall shape of the stanchion according to the invention with this wall thickness, the stanchion has increased stability for the increased load caused by the second loading level.In addition, the use of the stanchion system according to the invention allows the height of the vehicle body to be adjusted via the profiles which are telescopic in height.

[0031] Finally, a further aspect of the present invention is a commercial vehicle with the commercial vehicle body according to the invention, the stanchion according to the invention, and / or the stanchion system according to the invention. In addition to the commercial vehicle types already described, which are designed as semi-trailers, this also includes motor-driven tractors with a commercial vehicle body. These can have a commercial vehicle body designed as a double- or multi-decker body, as already described for semi-trailers.

[0032] In order to avoid repetitions here with regard to the advantages of the commercial vehicle body according to the invention or the commercial vehicle according to the invention, reference is made to the description of the advantageous embodiments of the stanchion according to the invention and the stanchion system according to the invention and the disclosure by this description is fully relied upon and vice versa.

[0033] With the commercial vehicle body according to the invention using the stanchion according to the invention and the stanchion system according to the invention, a method for positioning a second loading level or a loading field of a second loading level of a multi-level body with at least one first loading level in the form of a lower level for loading or unloading or for transporting transport goods can be carried out.The method includes the steps of lowering the second loading level from a parking position below the vehicle roof in the direction of the first loading level into a loading or unloading position or by lifting crossbeams or longitudinal beams of the second loading level or the loading field of the second loading level, automatically by means of a machine, in particular a forklift or stacker truck, or manually, the second loading level or at least one loading field of the second loading level is adjusted in its height positioning relative to the first loading level in such a way that the first loading level and the second loading level or at least one loading field of the second loading level are available at least for loading or unloading or for transporting goods or are transferred back from the loading or unloading position into the parking position.

[0034] The method for positioning the loading bays of the second loading level advantageously serves to raise the loading bays or the entire second loading level into the parking position below the roof of the multi-deck body and, if necessary, to position the second loading level in a loading or unloading position by lowering the loading bays in order to use the second loading level for loading or unloading pallets from the parking position below the roof. Positioning the loading bays for ramp loading is advantageously carried out using a pallet truck for loading and unloading, whereby the lowering and raising of each loading bay, including all components, can advantageously be carried out in a single lift, according to the invention. It can generally be assumed that ramp loading, which currently accounts for approximately 80-90 percent, will become more widespread in the future.

[0035] Advantageously, the method according to the invention for positioning the second loading level or the respective loading fields, regardless of whether side or ramp loading or unloading is carried out, can be carried out not only by the driver of the towing vehicle pulling the vehicle body, but can also be carried out by a loader, so that a trailer with the vehicle body according to the invention with double-deck loading can advantageously be used as a swap body. Preferred embodiments:

[0036] Further measures improving the invention are presented in more detail below with the description of preferred embodiments of the invention with reference to the figures. The features mentioned in the claims and in the description may be essential to the invention individually or in any combination. It should be noted that the embodiments illustrated in the figures are merely descriptive and are not intended to limit the invention in any way.

[0038] In the different figures, identical parts are always provided with the same reference symbols, which is why they are usually only described once.

[0039] Fig. 1 shows, in a perspective view obliquely from below, an embodiment of a stanchion base body 2 for a central stanchion 1.1. Formations 4 and 4.1 are formed integrally with the stanchion base body 2, i.e., as a single component, on each side of the stanchion base body 2. The formations 4 and 4.1 serve for the positive and / or material connection of the stanchion base body 2 with a holding and guiding device 3 (see also Fig. 5). In the formations 4 and 4.1, receiving means 9 are formed as recesses in the form of punched or milled cutouts. The same receiving means 90 in the form of recesses, whereby the receiving means 9 of the formations and the receiving means 90 of the holding and guiding devices 3 can generally also differ from each other, are formed in the holding and guiding device 3, as shown in Fig. 3 is shown. The holding and guiding device 3 is to be positioned on the formations 4 and 4.1 of the stanchion base body 2 in such a way that, in the form-fitting and / or material-locking connection between the stanchion base body 2 and the holding and guiding device 3, the recesses in the formations 4 and 4.1 and the associated holding and guiding devices 3 lie congruently one above the other, i.e., they are aligned with one another. The receiving means 90 of the holding and guiding device and the receiving means 9 in the formations 4 and 4.1 are, as shown, designed in pairs in the longitudinal extension of the stanchion 1 at different height positions H. The illustrated stanchion base body 2 with the formations 4 and 4.1 is produced in a rolling or roll forming process from a single piece of material, for example a flat iron or a flat steel, and has only one seam 10 which is to be joined in a materially bonded manner, in the area of ​​which seam the end faces 12 and 13 of the stanchion base body 2 rolled or roll formed from the flat iron or flat steel with formations 4 and 4.1 abut one another. The materially bonded connection of the two end faces is advantageously carried out by laser welding. The figure shows a plan view of the lower part of the stanchion base body 2. The notches 14 in the stanchion base body serve to accommodate a closure 40 for the detachable fastening of the stanchion 1 to a chassis of a commercial vehicle, which forms a closure system with a connecting element which can be fastened to the chassis of the commercial vehicle, in particular to the outer frame of the commercial vehicle. Details of the closure 40 are shown in . Fig. 6 shown.

[0040] Fig. 2 shows a sectional view of the stanchion base body 2 from Fig. 1 along the section line AA in Fig. 1. The profile of the stanchion base body 2 with the formed portions 4 and 4.1 is constructed mirror-symmetrically along the section line AA, which significantly simplifies the manufacturing process of the stanchion base body 2 with the formed portions 4 and 4.1 in a rolling or roll forming process. The formed portions 4 and 4.1 have a galvanization 5 in the cross-section in the shape of a dovetail 5.1, whereby the cross-section in the shape of the dovetail 5.1 widens from the stanchion base body 2 to the outside of the formed portions 4 and 4.1. This design enables a positive connection to be established between the formed portions 4 and 4.1 and the associated holding and guiding devices 3, whereby this connection can withstand tensile loads. Instead of the cross-section of the formed portion being designed as a dovetail, other shapes or galvanizations 5 can also be designed that can withstand tensile loads.Overall, the stanchion base body 2 and the formed portions 4 and 4.1 are formed from a single piece of material with the same wall thickness, for example, a flat steel or flat iron having the same wall thickness as the roll-formed stanchion base body 2 with the formed portions 4 and 4.1. It is of course also conceivable to form the stanchion base body 2 with the formed portions 4 and 4.1 from a single piece of material having half the wall thickness of the roll-formed stanchion base body 2 with the formed portions 4 and 4.1, in order to achieve the wall thickness necessary for the stability of the stanchion 1 by doubling the material, as is also provided for the advantageous design of the holding and guiding device 3 shown in the following figures. Preferably, in the area of ​​the widening, the portion formed as a dovetail 5.1 designed formation, before attaching the holding and guiding device to the formation and / or the U-profile 7 directed towards the formation 4 or 4.1, an adhesive is applied in the longitudinal extension of the stanchion base body 2 and / or the holding and guiding device 3 in order to form an overall positive and material-locking connection between the holding and guiding device 3 and the formation 4 or 4.1.

[0041] In the Fig. 3 shows a holding and guiding device 3 in a perspective view with a view of the C-profile 8 designed as a guide rail 800 for the load securing device. In the illustrated embodiment, see also Fig. 4, the holding and guiding device 3 is designed approximately in the form of a double-T profile 6, whereby the holding and guiding device 3 forms two profiles with a cross-section designed orthogonally to its longitudinal extent, a U-profile 7 and a C-profile 8, wherein the web 6.1 of the double-T profile 6 forms the adjacent base surfaces of the U-profile 7 and the C-profile 8, of which two profile legs 7.1, 7.2, 8.1 and 8.2 for each profile 7 and 8 extend in opposite directions. The two profile legs 7.1 and 7.2 of the U-profile 7, which is aligned towards the formation 4 or 4.1 of the stanchion base body 2, serve to overlap the formation 4 or 4.1 and to form and / or materially connect the holding and guiding device 3 and the stanchion base body 2. When the holding and guiding device 3 is placed in place, the web 6.1 between the two profiles 7 and 8 designed as recesses, the receiving means 90 are congruent with the receiving means 9 designed in the previous figures of the stanchion base body 2. In order to be able to design a connection between the stanchion base body 2 and the holding and guiding device 3 that is capable of withstanding tensile loads when the cross section of the formations is designed as a pronged connection 5, in particular in the form of a dovetail 5.1, the profile legs 7.1 and 7.2 are at least slightly cranked inwards in the direction of the stanchion base body 2 (see . Fig. 4). The C-profile 8, whose profile legs 8.1 and 8.2 are designed in the opposite direction to the profile legs 7.1 and 7.2 of the U-profile 7, are advantageously folded inwards at their end faces 80 and 80.1 in such a way that the free ends, namely the end faces of the profile legs 8.1 and 8.2, point towards each other (see Fig. 4). In this way, the C-profile 8 is designed as a guide rail 800 for the load securing device. In the illustrated embodiment, the holding and guiding device 3 is formed from a material strand, in particular a flat iron or a flat steel, in one piece from the material strand in the shape of the double-T profile 6. In contrast to the material thickness of the material strand from which the stanchion base body 2 and the formations 4 and 4.1 are formed, as shown in the previous figures, the material strand to be formed for the holding and guiding device 3 has a smaller wall thickness, here half the wall thickness, in relation to the wall thickness of the stanchion base body 2 and the formations 4 and 4.1, which allows the material strand to be formed into the shape of the double-T profile 6 in a rolling or roll forming process without material fatigue and thus to design the holding and guiding device 3 with the same wall thickness as is provided for the stanchion base body 3 with the formations 4 and 4.1.

[0042] As shown in the sectional view along section line BB (see Fig. 3) the Fig. 4, the holding and guiding device 3 produced in the rolling or roll forming process has only a butt joint 100 in the U-profile 7 directed towards the formation 4 in a wall 60 directed towards the formation 4, in the web 6.1 of the double-T profile 6. In the area of ​​the butt joint 100, the sides of the material strand meet after the rolling or roll forming process. To increase the strength of the holding and guiding device 3, the abutting sides can be joined to one another in a material-to-material bond, advantageously using a laser welding process or an adhesive process. The butt joint 100 between the sides of the material strand that meet after the rolling or roll forming process can also be deliberately left untreated, i.e. unconnected, thereby maintaining flexibility when attaching the holding and guiding device 3 to the formation 4 or 4.1.

[0043] Fig. 5 shows the completed stanchion 1 with the stanchion base body 2 with the formations 4 and 4.1 on the left and right in the figure, via which the holding and guiding devices 3 are connected to the stanchion base body 2 on the left and right. The stanchion 1 shown is suitable for use as a center stanchion. Due to the doubling of material on the holding and guiding device 3, in the embodiment shown it has the same wall thickness as the stanchion base body 2 with the formations 4 and 4.1, whereby the profile legs 7.1, 7.2, 8.1 and 8.2 of the holding and guiding devices 3 form a common outer surface with the stanchion base body 2, which extends above and below from the stanchion base body 2 into the outer surfaces of the holding and guiding devices 3 formed by the profile legs 7.1, 7.2, 8.1 and 8.2.

[0044] Finally, the Fig.6 shows an embodiment of a stanchion system 30 in the form of a central stanchion 1.1 according to the present invention. In the stanchion system 30, the stanchion base body 2 and the protrusions 4 and 4.1, with the associated holding and guiding devices 3, are formed from at least partially two profiles 210 and 220 that are displaceable relative to one another. The profiles 210 and 220 interlock in such a way that they mutually serve as rail guides 230 and / or support one another in adjustable and / or limited lengths of the stanchion base body 2 and the protrusions 4 and 4.1 with the holding and guiding devices 3. As shown, the profiles 210 and 220 are guided into one another in the form of insert elements in such a way that they serve mutually as rail guides 230 and thus the stanchion 1 as a whole can be shortened or lengthened relative to one another by pulling the profiles 210 and 220 into or apart, namely in particular is telescopic.At adjustable lengths of the stanchion 1, the profiles 210 and 220 can support each other. In the present case, stop points 240 are provided which prevent shortening or lengthening of the stanchion 1 beyond a certain length, or which allow the length of the stanchion 1 to be adjusted to predetermined positions. In the illustration, the view allows a view of the closure 40 accommodated in the stanchion 1. The closure allows a force-fitting and / or form-fitting connection of the stanchion 1 via a connecting element to a chassis of a commercial vehicle. A closure system with a slider from the applicant, which can also be provided in the stanchion 1 according to the invention, is described, for example, in DE 10 2020 102 186. The opening of the slider as well as the connecting element (not shown here) have bevelled edges and / or surfaces in the described embodiment.The edges and / or surfaces of the opening in the slider are designed to run in opposite directions to the beveled edges and / or surfaces of the connecting element that engages with the opening. This design has the advantage that, as the slider moves parallel to the longitudinal extension of the main body of the stanchion, the edges and / or surfaces of the opening and the edges and / or surfaces of the connecting element slide past each other at least partially spaced apart from each other. This allows, for example, a tilt of the trailer around its longitudinal axis to be compensated for when the stanchion 1 is secured using the described locking system. In this way, wedging of the slider in the connecting element can be prevented. QUOTES CONTAINED IN THE DESCRIPTION
