AI Technical Summary
The single-wall construction of commercial vehicle side walls makes it difficult to attach lashing devices for securing cargo and can lead to cargo striking pillar elements during loading and unloading, while existing double-wall constructions face challenges in simple and cost-effective assembly of side wall elements.
The side wall elements are connected to mounting means via a plug connection in a joining direction and secured against removal by a profile element extending longitudinally beyond the side wall, using positive, force, or material-locking connections to ensure stable attachment.
This method allows for simple, quick, and cost-effective assembly of side wall elements, ensuring they remain securely attached during operation, facilitating easy attachment of load securing devices and providing structural support.
Description
[0001] The invention relates to a box body of a commercial vehicle, in particular a truck, trailer or semi-trailer, with at least one side wall laterally delimiting a cargo space, wherein the side wall comprises a side wall element bordering the cargo space at least partially, at least one mounting means for mounting the side wall element, and at least one profile element extending longitudinally across the box body over the at least one side wall element and beyond the at least one side wall element on both sides. The invention further relates to a method for manufacturing such a box body.
[0002] Commercial vehicles, such as trucks, trailers, and semi-trailers, are primarily designed for transporting goods, preferably general cargo, on public roads. For this purpose, commercial vehicles have various types of superstructures that serve to accommodate the goods being transported in a cargo space.
[0003] For example, there are tarpaulin-covered bodies where the side walls and roof are enclosed by at least one tarpaulin section. The front wall of tarpaulin-covered bodies is usually a solid wall, while the rear wall is typically formed by two hinged doors to allow loading from the rear when needed. If a tarpaulin section can be moved along the side wall, these are also called curtain-sided vehicles. The roof of tarpaulin-covered bodies typically has laterally arranged beam structures in the form of longitudinal beams, which are connected to each other by bows to form a frame structure running transversely to the vehicle. This frame structure then supports the tarpaulin section that closes the roof, with the frame structure itself being supported by stanchions located at least at the corners of the vehicle.
[0004] In addition to tarpaulin-covered bodies, box bodies with fixed side walls, a fixed front wall, and a fixed roof, which enclose the cargo space, are also common. Because box bodies are enclosed, they are particularly suitable for transporting moisture-sensitive and / or temperature-sensitive goods, for example, for so-called dry transport and / or refrigerated transport. The rear wall of box bodies is usually closed by two hinged doors or a roller door.
[0005] Box bodies often feature double-walled panels on the front, roof, and / or side walls. These panels comprise an outer and an inner structural layer, as well as a core layer in between, typically made of a foamed plastic. The inner and / or outer layers themselves can be multi-layered if required. Box bodies with single-walled panels are also known; these panels have a surrounding frame or a grid structure of vertical and horizontal profiles enclosed by the panel. The panel is usually made up of one or more panel elements, which are at least substantially composed of fiberglass-reinforced plastic, steel, or aluminum, and may be painted as needed.
[0006] For example, to support the roof, the panels can be provided with a plurality of pillar elements for stiffening the panel. These pillar elements are oriented at least substantially transversely to the longitudinal direction of the panel and arranged longitudinally between the edges of the panel. In some cases, the pillar elements are then spaced apart longitudinally along the panel, similar to the center posts of tarpaulin structures, in order to support a beam of the structure. Furthermore, the pillar elements can be connected to the closed panel on the inside of the panel. The closed panel itself can be formed from several panel structural elements and can extend over at least substantially its entire length and height.
[0007] Commercial vehicles with corresponding box bodies are also known as dry freighters because the side walls or panels lack an insulating core layer of foamed plastic and only have a single outer structural layer. This single-layer construction of the side walls makes it difficult to attach lashing devices for securing cargo, such as ratchet straps or tensionable chains. With box bodies featuring double-layered side walls with a core layer between two structural layers, the lashing device can be easily attached to the inner layer and, if necessary, at least partially secured in the core layer. These lashing devices typically have openings or slots into which hooks of cargo securing devices can be inserted before being tensioned to secure the load.
[0008] This single-wall construction of the side walls often makes loading the box body more difficult, as the cargo can strike the pillar elements during loading and unloading. To prevent this, rub rails are sometimes provided at approximately mid-height of the side wall. Alternatively or additionally, other side wall elements besides rub rails or lashing points can be used, for example, to provide a roughly flat side wall adjacent to the cargo space, as is known from box bodies with double-wall construction. Regardless of the type of side wall elements, their installation on the side walls of dry cargo vessels is not possible, or only possible to a limited extent, in a manner already known from the manufacture of box bodies with double-wall construction.
[0009] US 7 011 358 B2 discloses a box body similar to the preamble of claim 1.
[0010] Therefore, the present invention is based on the objective of designing and further developing the case construction and the method of the type mentioned at the outset and explained in more detail above in such a way that simple, cost-effective and quick assembly of side wall elements is made possible.
[0011] This problem is solved in a box body according to the preamble of claim 1 in that the at least one side wall element is positively connected to the at least one assembly means by at least one plug connection in at least one joining direction and that the side wall element is secured against being pulled out of the assembly means opposite to the joining direction of the side wall element by the profile element via an at least indirect connection of the profile element to the side wall element on the one hand and with components of the side wall provided in the longitudinal direction of the box body on both sides of the at least one side wall element on the other hand.
[0012] The aforementioned problem is further solved according to claim 10 by a method for manufacturing a box body, in particular according to one of claims 1 to 9, with at least one side wall and a cargo space laterally bounded by the at least one side wall, in which a side wall element, in particular in the form of a lifting device having receptacles for attaching load securing devices, is connected at least sectionally to the cargo space via a plug connection in a joining direction to a mounting device in a form-fitting manner and in which the at least one profile element is connected at least indirectly to the side wall element and to components of the side wall provided in the longitudinal direction of the box body on both sides of the at least one side wall element, such that the side wall element is secured against being pulled out of the mounting device in the opposite direction of the joining direction of the side wall element by the connection of the side wall element with the components provided laterally to the side wall element.
[0013] The at least one side wall element is thus attached to the side wall in two ways. Firstly, the at least one side wall element is connected to at least one mounting element of the side wall. This is done by connecting the side wall element to the mounting element in at least one joining direction relative to the mounting element. It is therefore fundamentally irrelevant whether the side wall element is inserted into the mounting element, or vice versa, or both. Moreover, it will be particularly simple and therefore often preferred if the joining of the side wall elements and the mounting element occurs in a single joining direction. However, the joining process can also involve two different joining directions successively. It is also conceivable that the joining direction changes continuously during the joining process.The at least one joining direction is of particular importance in this case because the plug connection can be separated again, if necessary or at least theoretically, by a movement of the at least one side wall element against the at least one joining direction with respect to the at least one assembly means, which is undesirable in this case.
[0014] Even if the connector is designed in such a way that at least one side wall element should no longer accidentally detach from at least one mounting element, this cannot usually be reliably ruled out during operation of the commercial vehicle due to twisting and vibrations. This is all the more true because load securing devices attached to the side wall element can pull on the side wall elements in very different directions. This is especially true if only a single joining direction is provided, which will usually be preferred for manufacturing reasons.
[0015] It is particularly simple, for example, if the at least one side wall element is inserted into the at least one mounting device in a vertical, top-to-bottom direction. In this case, a positive fit can form between the side wall element and the mounting device in the downward vertical direction relative to the side wall element. The connection then remains engaged with the at least one mounting device simply due to the weight of the at least one side wall element. However, this connection can also loosen during further manufacturing of the box body and / or during operation of the associated commercial vehicle. With a different joining direction, a positive fit between the at least one side wall element and the mounting device can be formed in a different direction, although this other joining direction might be less preferred in many cases.Such a joining direction can, for example, be perpendicular to the side wall and aligned with it. The side wall element can then simply be attached vertically to the side wall. In this case, a positive fit can also be formed in the direction parallel to the side wall and downwards. To provide a positive fit also in the direction perpendicular to the side wall and into the cargo space, the plug-in connection can be designed as a snap-fit connection.
[0016] To prevent accidental loosening of the connection between the side wall elements and the mounting hardware, the at least one side wall element is additionally connected, at least indirectly, to a profile element that extends over the side wall element and, in the longitudinal direction of the box body, also beyond it. An indirect connection could therefore be achieved by connecting the at least one side wall element and the side wall components provided on both sides of the side wall element with a very short intermediate section, and this intermediate section then being connected to the longer profile element. Functionally, however, this means nothing significantly different for the side wall element than if the side wall element were directly connected to the profile element.
[0017] Since the profile element extends longitudinally along the body of the box beyond at least one side wall element on both sides, and a multi-part profile element would be harmless in this context, the profile element can be attached not only to the at least one side wall element but also to components of the side wall that are located longitudinally outside the at least one side wall element. If the profile element were connected only to the at least one side wall element, its plug connection with the at least one mounting element could still loosen. In the case of a vertical downward direction of attachment, this would be less likely due to the additional weight force of the profile element acting on the plug connection, but it is certainly not impossible.
[0018] By connecting the profile element to the at least one lifting element and the components provided laterally to the lifting element, the side wall element can be easily secured against unwanted removal from the mounting device in the opposite direction of its insertion. This is particularly relevant if the profile element must be installed during the manufacturing of the box body anyway. In this case, the installation of the profile element can be combined with securing the at least one side wall element. From a manufacturing perspective, this offers the advantage of simple and rapid production. For example, the at least one side wall element can be quickly and easily hooked into the at least one mounting device from above. For subsequent manufacturing steps, the at least one side wall element is sufficiently secured in its position.In a later manufacturing step, the profile element can then be mounted without the side wall element already being joined, thus aligned and positioned. This also secures the at least one side wall element to the at least one mounting device in a single step. The assembly of the at least one side wall element is therefore a two- or multi-step process, but overall very simple, reliable, quick, and cost-effective.
[0019] For the sake of clarity and to avoid unnecessary repetition, the case design and the method for manufacturing the case design are described together below, without differentiating between the case design and the method in detail. However, the context will make it clear to those skilled in the art which features are particularly preferred with respect to the case design and the method.
[0020] In a first particularly preferred embodiment of the box body, the at least one side wall element is positively locked in a direction perpendicular to the side wall and into the cargo space by means of the plug connection with the at least one mounting means. Such a positive locking mechanism has several advantages. On the one hand, the at least one side wall element is held against the at least one mounting means by its own weight. On the other hand, the at least one side wall element can be reliably braced against the at least one mounting means if a load securing device is to be attached to the side wall element and tensioned against the load for load securing purposes.
[0021] To more reliably prevent the at least one side wall element from being accidentally separated from the at least one mounting device, the at least one plug connection between the at least one side wall element and the at least one mounting device can be designed as a snap-fit connection. This is particularly advantageous if the side wall is rotated or pivoted during the manufacture of the box body in such a way that the at least one side wall element could otherwise slip out of the at least one mounting device contrary to the joining direction.
[0022] If at least one side wall element has attachment points for load securing devices, the side wall element is particularly suitable for use in load securing. Therefore, the side wall element can be designed as a lifting device with attachment points for load securing devices and / or loading aids. In this case, at least one essential function of the side wall element is load securing or the attachment of loading aids. Load securing devices can include, for example, tension straps, locking bars, or round bars. Loading aids can include devices used for loading. These can include, for example, clothes rails for hanging clothing to be transported or double-deck beams for setting up pallets on a second level above the loading floor.
[0023] In this context, it is particularly advantageous if the side wall element, in the form of the lifting device, has receptacles in the form of openings. This allows load securing devices or load aids to be easily hooked into the receptacles and reliably secured in at least one lifting device. This is especially true if the openings are shaped like keyholes or upright figure eights. Alternatively or additionally, the at least one side wall element, in particular the lifting device, can be made of sheet metal. The side wall element, in particular the lifting device, is then both lightweight and stable. Furthermore, the side wall element, in particular the lifting device, can be easily manufactured from sheet metal. The aforementioned advantages are even more pronounced if the at least one side wall element, in particular the lifting device, is formed from a single sheet of metal, especially by stamping.
[0024] The advantages of the invention are particularly evident when the at least one side wall element extends at least substantially from a loading floor to the roof of the box body. Otherwise, due to their size, such side wall elements can only be installed with considerable effort. For the same reason, the same applies alternatively or additionally to side wall elements that have a height of at least 2 m, preferably at least 2.5 m, and / or a width of at least 1 m, in particular at least 1.5 m, and in particular at least 2 m.
[0025] If the profile element secures the side wall element against being pulled out of the mounting device contrary to the joining direction by means of a positive-locking, force-locking, and / or material-locking connection with the side wall element, the profile element can be easily joined using known methods without necessarily requiring special preparations with regard to the at least one side wall element or the at least one mounting device. For this reason, it may also be advantageous, alternatively or additionally, if the profile element is positively locked, force-locking, and / or material-locking connected to the side wall components provided on both sides of the at least one side wall element in the longitudinal direction of the box body.
[0026] The box body can be manufactured simply yet quite rigidly if at least one mounting element is designed as a pillar extending at least substantially from the loading floor to the roof to stiffen the side wall. Such a pillar element can then stiffen the side wall and, if necessary, support the roof against the loading floor, while simultaneously serving as a mounting element for the at least one side wall element. For both the reliable mounting of the side wall element and the stiffening of the side wall, it is advantageous if the at least one pillar element is designed as a metal profile, and for weight reasons, particularly as a hollow metal profile.
[0027] If several mounting elements are provided, spaced apart from each other in the longitudinal direction of the box body, in particular at regular intervals, mounting points for connecting at least one side wall element to the mounting elements can be provided at multiple locations along the longitudinal direction of the box body. If the mounting elements are pillar elements, this can simultaneously achieve suitable stiffening of the side wall and secure support of the roof against the loading floor.
[0028] To utilize at least one mounting device as efficiently as possible, two different side wall elements can be positively connected to this mounting device, or at least to some of several mounting devices, by means of a plug-in connection in one joining direction of the side wall element to the mounting device. In this way, one mounting device can serve to fix two different side wall elements.
[0029] The construction and thus the manufacturing of the box body can be simplified if, of the components of the side wall provided longitudinally on both sides of the at least one side wall element, at least one such component is a side wall element and / or a mounting element. Therefore, further side wall elements can be provided on both sides of the at least one side wall element, with the side wall elements serving to mount each other. Alternatively, the profile element can be fixed to a mounting element on one or both sides of the at least one side wall element. In both cases, no additional components are required to mount the profile element. Instead, existing side wall elements and / or mounting elements can be used.Furthermore, it can be particularly simple and practical if the profile element is designed to extend at least substantially over the entire longitudinal extent of the side wall and / or the cargo area. This allows multiple side wall elements to be fixed side-by-side with a single profile element. In addition, profile elements that would be required anyway for the construction of the box body can also be used to fix the side wall elements, particularly over the entire longitudinal extent of the side wall and / or the cargo area.
[0030] In this context, but also independently thereof, it is generally particularly advantageous if the profile element extending beyond at least one side wall element on both sides is positioned adjacent to the loading floor. A further profile element can then be positioned adjacent to the roof. However, it would also be conceivable to provide only one of these profile elements or one located elsewhere. In the area of the loading floor and in the area of the roof, profile elements only minimally impede the attachment of load securing devices to the side wall elements. The same applies to the actual load securing using the side wall elements. In the case of a profile element in the area of the loading floor, a base rub rail that would be required anyway can be used as the profile element.In the roof area, a corner angle can be used as an additional or alternative profile element, tightly connecting the side wall to the roof adjacent to the cargo area. This allows for functional synergies with regard to the base rub rail and / or the corner angle.
[0031] In a first particularly preferred embodiment of the method, the side wall element is secured against being pulled out of the mounting device contrary to the joining direction by a positive-locking, force-locking, and / or material-locking connection with the profile element. As a result of this additional connection, it can be ensured simply and cost-effectively that the at least one side wall element permanently assumes its original and predetermined position on the side wall.
[0032] Alternatively or additionally, the profile element can be positively, force-fit, and / or material-fitted to the side wall components located longitudinally on both sides of at least one side wall element of the box body. This, too, can be achieved simply, quickly, and cost-effectively using joining principles that are known per se.
[0033] The at least preliminary assembly of the at least one side wall element to the at least one mounting means can be carried out in a simple and quick manner by forming the plug connection between the at least one side wall element and the at least one mounting means for positive locking of the side wall element to the mounting means in a direction perpendicular to the side wall and into the cargo space. The at least one side wall element can thus be inserted into the at least one mounting means from above, by which the side wall element is supported against detachment or bulging towards the cargo space in the case of load securing with a load securing device suspended in the side wall element.
[0034] If at least one plug connection between the at least one side wall element and the at least one mounting device is designed as a snap-fit connection, the side wall element can also be positively secured against being pulled out of the mounting device in the opposite direction of assembly. However, even such snap-fit connections do not guarantee that the removal of the removal device from the mounting device in the opposite direction of assembly is prevented in every case.
[0035] The at least one side wall element can be conveniently connected to mounting elements spaced apart from each other along the longitudinal direction of the box body, particularly those designed as pillar elements. This creates points at various locations along the box body where the at least one side wall element can be inserted. In addition, the mounting elements can, if necessary, further stiffen the side wall. If several mounting elements and several side wall elements are provided, at least some of the mounting elements can be used particularly effectively if two different side wall elements are connected to them via a plug-in connection, positioned adjacent to each other.
[0036] The construction of the box body is simple and requires only a small number of components if, for example, the profile element is connected to at least two side wall elements positioned side-by-side along the length of the box body and / or to at least one mounting element, particularly one designed as a pillar element. The at least one additional side wall element can then also serve as an attachment point for load securing devices. Alternatively or additionally, the profile element can extend at least substantially over the entire length of the side wall and / or the cargo space. In this way, the profile element can provide a function along the entire length of the side wall or the cargo space. Regardless of this, the profile element can also, with sufficient length, secure a large number of side wall elements to the side wall.
[0037] For securing cargo to the side wall, it is particularly advantageous if the profile element is positioned adjacent to the loading floor and / or the roof. The remaining area of the side wall at the location of the at least one side wall element can then be used for load securing. For ease of manufacturing, it is also preferable if the at least one profile element serves as a base rub rail and / or corner bracket for connecting the side wall to the roof adjacent to the cargo area. Base rub rails and corner brackets are often required anyway, and these can then serve the additional function of securing the at least one side wall element.
[0038] The invention will now be explained in more detail with reference to a drawing that illustrates only one embodiment. The drawing shows Fig. 1 shows a commercial vehicle towed by a tractor unit with a box body according to the invention in a schematic perspective view; Fig. 2 shows a detail of the box body made of Fig. 1 In a schematic view from the cargo area, Fig. 3 shows a detail of the box body. Fig. 1 During manufacturing, a detailed view from the cargo area, Fig. 4A-C shows several steps of joining the side wall. Fig. 2 in a sectional view of a detail of the side wall and Fig. 5 a further step of joining the side wall from Fig. 2 in a schematic view from the cargo area.
[0039] In the Fig. 1 Figure 1 depicts a commercial vehicle N in the form of a semi-trailer, towed by a tractor unit Z, carrying a box body 1. The box body 1 comprises a fixed roof 2, a fixed front wall 3, fixed side walls 4, and a rear wall 6 with rear doors 5. The side walls 4 are constructed in a single-shell design, similar to a dry cargo vehicle. The side walls 4 thus include an outer, structural layer in the form of a panel 7, which can be composed of several panel elements along the longitudinal direction of the box body 1. The panel 7 has at least one layer made of glass fiber reinforced plastic, steel, or aluminum. Additional layers are possible and do not necessarily contribute to the strength of the panel 7, but can primarily provide the desired surface finish. For example, the outer surface can be painted and the inner surface coated with a hygienic finish.Panel 7 does without an additional, inner, especially structuring, top layer, as well as a core layer made of, for example, a foamed plastic.
[0040] In the Fig. 2 The side wall 4 is further shown in detail as seen from the cargo space 8. To support the roof 2 against the loading floor 9 and to stiffen the side wall 3, a series of pillar elements 10, 11 are provided on the inside of the panel 7 of the illustrated and thus preferred box body 1. These pillar elements are spaced apart from one another, particularly at regular intervals. The illustrated and thus preferred pillar elements 10, 11 extend perpendicular to the loading floor 9 and at least substantially from the roof 2 to the loading floor 9 of the box body 1. The pillar elements 10, 11 of the illustrated and thus preferred box body 1 are designed differently. Pillar elements 10 are provided that are designed as double-deck rails and have openings 12 for inserting double-deck beams.The double-deck beams (not shown), on which cargo such as pallets can be placed, extend in a known manner transversely to the box body 1 from side wall 4 to side wall 4. In addition, pillar elements 11 without openings for inserting double-deck beams are provided. Lifting devices 13 for attaching load securing devices, such as tensionable chains or tension straps, can be attached to both types of pillar elements 10 and 11, so that the pillar elements 10 and 11 serve as mounting means 14 for the side wall elements 13. Instead of pillar elements 10 and 11, other mounting means 14 could also be provided for mounting the side wall elements 13.The pillar elements 10, 11 are, however, regularly preferred because they can perform several functions simultaneously, namely, in particular, supporting the roof 2, stiffening the side wall 4, if necessary, receiving double-deck beams and mounting side wall elements 13. The illustrated and thus preferred pillar elements 10, 11 are formed by a hollow metal profile, which, however, does not have to be completely closed.
[0041] The illustrated and thus preferred side wall elements 13 are designed as attachment points for securing load securing devices and / or load securing aids and, for this purpose, have several rows of receptacles 15 in the form of openings into which hooks or the like of load securing devices such as tension straps can be inserted. However, other load securing devices, load securing aids, or equipment can also be inserted into the receptacles 15 of the side wall elements 13. For this purpose, the receptacles 15 form keyhole-shaped openings and are arranged in several rows. However, neither of these features is mandatory. It is also merely preferred that the side wall elements 13 are each made from a single sheet of metal, which may be formed, in particular stamped, to fulfill the desired functions. Both in the Fig. 1 as well as in the Fig. 2 For the sake of clarity, not all side wall elements 13 are shown. In the illustrated and thus preferred box body 1, the side wall elements 13 extend at least substantially along the entire longitudinal extent of the box body 1, with at least partial exception of the mounting means 14 in the form of the double-decker rails. However, the side wall elements 13 could also be provided only in sections along the longitudinal extent of the box body 1. It would also be conceivable that only a single side wall element 13 is provided, which could then be much wider than the side wall elements 13 shown, if necessary.
[0042] It is merely preferred, but by no means mandatory, that the side wall elements 13 extend at least substantially from the loading floor 9 to the roof 2. In this way, the side wall elements 13 extend upwards to behind a profile element 16 in the form of a corner angle, which covers the connection between the side wall 4 and the roof 2 adjacent to the loading space 8 and extends over the entire length of the loading space 8. The side wall elements 13 extend downwards to behind a profile element 17 of a base rub rail, which also extends over the entire length of the loading space 8 and covers the connection between the side wall 4 and the loading floor 10. The profile element 17 in the form of a base rub rail is designed such that cargo, in particular pallets, does not damage the side wall 4 during loading and unloading, but rather slides off the profile element 17 in the form of the base rub rail.In the illustrated and thus preferred box body 1, the profile element 17 in the form of the baseboard is bonded to the side wall elements 13 by means of a material bond, as is the profile element 16 in the form of the corner angle. However, a positive-locking and / or force-locking connection of the baseboard and / or the corner angle to the side wall elements 13 would also be conceivable.
[0043] Furthermore, a baseboard and / or a corner bracket are only preferred. Other profile elements could also be provided. These profile elements would then not necessarily have to extend over the entire length of the cargo space 8.
[0044] However, the profile elements are wider in the longitudinal direction of the box body 1 than the width of at least one side wall element 13. Accordingly, the profile element 16, 17 projects laterally on both longitudinal sides relative to the side wall element 13. These projecting areas of the profile element 16, 17 allow the profile element 16, 17 to be connected not only to the at least one side wall element 13, but also to other components of the side wall 4 laterally adjacent to the side wall element 13. In the illustrated and thus preferred box body 1, these are further side wall elements 13 and / or mounting elements 14. Other components would also be possible in principle. Furthermore, it is preferred if side wall elements 13 are provided on both side walls 4, and in particular if the two side walls 4 are designed identically.
[0045] The side wall elements 13 are, as shown in the Fig. 3 As indicated by the arrows, the side wall elements 13 are connected to the mounting means 14 via a plug connection 18. In the illustrated and thus preferred box body 1, tabs 19 are provided on the side wall elements 13 and recesses 20 for inserting the tabs 19 into the mounting means 14. The side wall elements 13 can be inserted into the mounting means 14 and then inserted into the mounting means 14 in a joining direction F that points at least substantially vertically downwards. This creates positive-locking connections that direct the side wall elements 13 in a direction perpendicular to the side wall 4 and into the cargo space 8, and support them downwards against the mounting means 14. This is particularly advantageous in the Fig. 4A-C The mounting means 14 could also have tabs, especially upward-pointing ones, which engage in recesses of the side wall elements 13 from below to join the plug connection.
[0046] To facilitate insertion of the tabs 19 into the recesses 20 of the mounting means 14, the tabs 19 shown, which are preferred in this respect, are bent backwards in sections adjacent to their free ends 21. Furthermore, the upper end 22 of the tab 19 is bent backwards so that this upper end 22 engages under the upper edge 23 of the recess 20 in the mounting means 14 and prevents the side wall element from being pulled out against the joining direction F, i.e., the pull-out direction, by means of a positive locking mechanism with the mounting means 14. When manufacturing the side wall 4, the side wall elements 13 can only be inserted into the mounting means 14 in the manner described. Final joining of the side wall elements 13 can then only take place together with the assembly of the side wall 4 to the loading floor 9 and the roof 2. In the meantime, the side wall elements 13 remain held in place by the plug-in connection on the mounting means 14.
[0047] In the Fig. 5Figure 1 shows a detail of the side wall 4 with inserted side wall elements 13. In a next step, the side wall elements 13 and certain pillar elements 10 are connected to each other via profile elements 16, 17 in the form of the corner angle and the base skirting board. In the illustrated and thus preferred box body 1, the profile elements 16, 17 are bonded directly to the side wall elements 13 and the pillar elements. After this bond has cured, it prevents the side wall elements 13 from sliding upwards out of the associated mounting elements 14 against the joining direction F, i.e., the extension direction. The side wall elements 13 are connected, at least indirectly, via the profile elements 16, 17, laterally to other side wall elements 13 and mounting elements 14 of the same side wall 4.The side wall elements 13 could also be connected to the profile elements 16, 17 only indirectly. The side wall elements 13 of the side wall 4 are ultimately connected to other components of the side wall 4 in such a stable and permanent manner that accidental removal of a side wall element 13 from the associated mounting device 14 in the opposite direction to at least one joining direction F, i.e., one extension direction, is prevented.
