Description

The present invention relates to a device for cargo securing in a utility vehicle cargo area enclosed by a cargo floor, side walls and a roof structure. The invention further relates to a utility vehicle structure having such a device.Modern commercial vehicles have in some cases already integrated systems for cargo securing in the cargo space. Such a system is marketed by the applicant under the trademark "CargoMaster". This is an expander cable system for cargo securing, with which it is not necessary to cover lashing straps, nets or tarpaulins over the cargo. Cargo securing means such as lashing straps, nets or tarpaulins can be pulled under the vehicle roof and stored there as required. The load securing means are therefore available held ready for grip under the vehicle roof for a simple and rapid lashing process.Such a cargo securing system currently has separate rails which are fastened to roof straps or roof profiles of the relevant utility vehicle structure. The rails support anchoring elements for securing the expander cable system. These rails should have the smallest possible distance from the vehicle roof in order to be able to position the clamping means as close as possible to the vehicle roof in order not to impede loading and unloading operation and not to restrict the loading volume.The minimum distance of the rail from the vehicle roof is predefined by the method of fastening the respective rail to the roof strap and any collision structures limiting the assembly process, which collision structures are formed by the profile shape of the roof strap.Against this background, the present invention is based on the technical problem of specifying an improved device for cargo securing and a utility vehicle having such a device.The technical problem described above is solved in each case by the features of the independent claims. Further embodiments of the invention are evident from the dependent claims and the description below.According to a first aspect, the invention relates to a device for cargo securing in a commercial vehicle cargo area enclosed by a cargo floor, side walls and a roof structure, the device having: a corner profile which is arranged in a transition between the respective side wall and the roof structure and which supports the roof structure along its longitudinal edge, wherein the corner profile has cavities and longitudinal grooves over its length, wherein a longitudinal groove of the corner profile is open towards the cargo area and forms a running rail, wherein an anchoring element is provided which has at least one roller and a connecting section connected to the roller for fastening a clamping means, wherein the roller is held displaceably in the running rail and the connecting portion connected to the roller projects into the loading space penetrating an opening of the running rail, and wherein the corner profile is formed in one piece and the running rail is an integral component of the corner profile.In comparison with previously known solutions, the corner profile accordingly has an integrated longitudinal guide in the form of the running rail, so that a compact arrangement can be achieved. Because the running rail is an integral component of the corner profile, a particularly small distance of the running rail from the roof structure can be achieved. It can thus be ensured that the clamping means can be positioned as close as possible to the vehicle roof in order not to impede loading and unloading operation and not to restrict the loading volume.The running rail is therefore in particular not part of an additional profile connected to the corner profile, which has been connected to the corner profile by means of a method for producing a releasable or non-releasable connection, such as welding, riveting, soldering, screwing or the like. The device therefore does not have an additional profile which forms the running rail, since the running rail is already integrated into the corner profile.The corner profile here denotes a load-bearing component of a commercial vehicle structure, wherein such a corner profile is referred to in technical terms as a "roof strap".The corner profile can have been produced by extrusion, wherein the running rail has been produced partially or completely in a moulding manner in the extrusion. Alternatively or additionally, it can be provided that the running rail and / or further grooves of the corner profile have been produced by machining.The corner profile can have a further longitudinal groove which is open towards the cargo space and adjoins the running rail. In particular, it can be provided that an illumination element is arranged in the further longitudinal groove, such as an LED strip, an LED rail or the like. Thus, an illumination of the cargo space can be improved.A wall section of the running rail can be formed integrally with a wall section of the further longitudinal groove. The further longitudinal groove can also be compactly integrated into the profile cross section of the corner profile. The further longitudinal groove can have been produced in a primary shape by press-forming and / or by machining.The corner profile can have an L-shaped configuration as viewed in a cross section, with a first profile leg and with a second profile leg, wherein the first profile leg is assigned to the roof structure and wherein the second profile leg is assigned to the side wall.The corner profile can have a groove facing away from the cargo space and open to the roof structure for receiving a support roller of a roof bow and / or a sliding system.Alternatively or additionally, the corner profile can have a groove facing away from the cargo space and open to the side wall for receiving a supporting roller of a roof bow and / or a sliding system.In particular, the corner profile can be a roof chord for full-plane or curtain-side vehicles.The invention further relates to a utility vehicle structure, having a utility vehicle cargo area which is surrounded by a cargo floor, side walls and a roof structure, having a device according to the invention for cargo securing, wherein two corner profiles are provided along opposite longitudinal edges of the roof profile and wherein each of the corner profiles is assigned at least one anchoring element.A clamping means can extend between the corner profiles and be fastened on two sides, so that the clamping means spans a width of the loading floor, wherein the clamping means is held on opposing anchoring elements.The tensioning means can be, for example, an expander cable system of the Applicant's "CargoMaster" type. Load securing means, such as lashing straps, nets or tarpaulins, can be held on a tensioning means.It can be provided that a plurality of opposing anchoring elements are held on the corner profiles and a plurality of clamping means extend between the corner profiles and are fastened to the anchoring elements on two sides.The invention is described below with reference to drawings illustrating exemplary embodiments. They show in each case schematically: FIG. 1 shows a first device according to the invention in a cross section; FIG. 2 shows a second device according to the invention in a cross section; FIG. 3 shows a utility vehicle structure according to the invention in a cross section.FIG. 1 shows a device 2 according to the invention for cargo securing in a utility vehicle cargo area L enclosed by a cargo floor, side walls S and a roof structure D.The device 2 has a corner profile 4, which can also be referred to as a roof strap.The corner profile 4 is arranged in the fully assembled state in a transition between the respective side wall S and the roof structure D and supports the roof structure D along its longitudinal edge.The corner profile 4 has cavities 6 and longitudinal grooves 8 over its length, some of which have been provided with reference numerals by way of example. The longitudinal extension of the corner profile 4 is oriented perpendicular to the plane of the drawing. The cross section shown is therefore oriented perpendicular to the longitudinal extent of the corner profile 4.A longitudinal groove 10 of the corner profile 4 is open toward the cargo space L and forms a running rail.The device 2 has an anchoring element 12. The anchoring element 12 has a roller 14 and a connecting section 16 connected to the roller 14 for fastening a clamping means 17.The roller 14 is slidably supported in the running rail 10, and the connecting portion 16 connected to the roller 14 penetrates an opening 18 of the running rail 10 and protrudes into the loading space L. The opening 18 is a horizontal longitudinal slit. The connecting portion 16 protrudes horizontally into the cargo space L.The corner profile 4 is formed in one piece and the running rail 10 is an integral component of the corner profile 4.The running rail 10 is therefore not part of an additional profile connected to the corner profile 4, which has been connected to the corner profile 4 by means of a method for producing a releasable or non-releasable connection, such as welding, riveting, soldering, screwing or the like. The device 2 therefore does not have such an additional profile, since this is not necessary due to the integration of the running rail 10 into the corner profile 4.The corner profile 4 shown has been produced by extrusion, wherein the running rail 10 has likewise been produced during the production of the corner profile 4 as an integral component thereof in a forming manner in the extrusion.The corner profile 4 has a further longitudinal groove 20 which is open towards the cargo space L and adjoins the running rail 10. In the further longitudinal groove 20, an illumination element 22 is arranged, namely an LED strip. Due to the fact that the LED strip is recessed into the profile, the LED strip is protected from mechanical damage.A wall section 24 of the running rail 10 is formed integrally with a wall section 26 of the further longitudinal groove 20.The corner profile 4 has an L-shaped configuration when viewed in cross section, with a first profile limb 28 and with a second profile limb 30.The first profiled leg 28 is assigned to the roof structure D. The second profiled limb 30 is associated with the side wall S.The corner profile 4 has a groove 32 facing away from the cargo space L and open to the roof structure D for receiving a support roller 34 of a roof bow 36.The corner profile 4 has a groove 38 facing away from the cargo space L and open to the side wall S for receiving a support roller 40 of a sliding support 42.FIG. 2 shows a further embodiment of a device 44 according to the invention, wherein, in order to avoid repetitions, only the differences from the exemplary embodiment described above are discussed and the same reference numerals are assigned to the same features.The device 44 differs substantially from the device 2 in that the second leg 30 of the device 44 is configured shorter than the second leg 30 of the device 2.Since the running rail 10 is completely integrated into the profile cross section, there is a significant saving in space compared to solutions with an additional additional running rail mounted on the profile. The device therefore occupies the same installation space that known solutions without running rail take.FIG. 3 shows a utility vehicle structure 46 with a utility vehicle cargo area L, which is surrounded by a cargo floor B, side walls S and a roof structure D, with a device 2 for cargo securing.Two corner profiles 4 are provided along opposite longitudinal edges of the roof structure D. Each of the corner profiles 4 is assigned at least one anchoring element 12.A clamping means 17 extends between the corner profiles 4 and is fastened on two sides, so that the clamping means 17 spans a width b of the loading floor B, wherein the clamping means 17 is held on opposing anchoring elements 12.A load securing means 48, in the present case a lashing strap, is held on the clamping means 17.Reference numerals denote reference numerals2 Device 4 corner profile 6 cavity 8 longitudinal groove 10 longitudinal groove 12 anchoring element 14 roller 16 connecting portion 17 clamping means 18 opening 20 longitudinal groove 22 lighting element 24 wall portion 26 wall portion 28 profile leg 30 profile leg 32 groove / longitudinal groove 34 supporting roller 36 roof bow 38 groove / longitudinal groove 40 supporting roller 42 sliding means 44 device 46 utility vehicle structure 48 load securing means D roof structure S side wall L utility vehicle loading space B loading floor b width
