The present invention relates to a loading space structure, in particular of a truck, with a loading space door that can be pivoted about a vertical axis of rotation and has a seal for sealing interaction with a counter wall of the loading space structure. Loading space structures of this type are known with door systems in which the door leaves are pressed onto the portal frame by means of espagnolette locks. The contact surface between the portal frame of the loading space structure and the loading space door is designed as a smooth surface. With this construction, snow can collect on the upper edge of the door in winter and rainwater in summer, so that moisture can penetrate into the vehicle through the contact surface, even with the best seal. This is particularly the case when the vehicle is stationary. A loading space structure of this type is also known from EPO 698 515 A2. The box body of a truck described therein has a front loading compartment door with an inner wall for sealing interaction with the box body, the inner wall having an integral sealing wall in its edge area, also in the area of edge hinge members. This correspondingly circumferential sealing wall of the loading compartment door is pressed against a smooth counter wall surrounding the door opening of the loading compartment body in the closed position. Based on this, it is an object of the present invention to further develop a generic loading compartment body in a manner that is advantageous for use.

The problem is solved first and foremost by the subject matter of claim 1, which is based on

VGN 265 098 23075Nl Mü./Bz./We/Or. 01.09.1 999

is that the seal is assigned a drainage edge which extends from an upper edge region of the loading compartment door in the closed position in the direction of the loading compartment into a channel bordered by the opposing wall and facing the loading compartment door in the closed position. This design according to the invention ensures that rainwater or snow hitting the seal on the upper edge of the loading compartment door only reaches the top of the drainage edge and is drained away from it, so that no moisture can penetrate into the interior of the loading compartment structure. It is preferably envisaged that the drainage edge extends from the upper edge region of the loading compartment door in an upward direction in the direction of the loading compartment. Moisture reaching the top of the drainage edge is drained away by the corresponding slope in the direction of the side of the drainage edge facing away from the channel, which provides a good sealing effect. In a preferred embodiment, the channel extends in its longitudinal direction in the closed position of the loading compartment door parallel to the loading compartment door and continuously over the entire length of the upper edge, which results in a uniformly good sealing effect across the width of the door. It is further preferred that the loading space structure has a cross member and that the channel is formed in or on the cross member. Alternatively, it is also possible for the loading space structure to have a cross profile connected to the cross member and for the channel to be formed in or on the cross profile. In both cases, a space-saving and thus advantageous design of the seal is achieved. In further detail, it is possible for the cross member and/or the cross profile to have a closed hollow profile in cross section. Depending on the application, however, the cross member and/or the cross profile

VGN 265 098 23075N1 Mu./Bz./We/Or. September 1, 1999

in cross-section, alternatively or in combination, also have an open hollow profile, in particular a hollow profile with an S-shaped cross-section. The loading space structure according to the invention can thus also be adapted to a wide variety of structural requirements with regard to the counter wall in the area of the upper edge of the loading space door. In an expedient embodiment, it is provided that the channel is formed from the outside into the closed hollow profile, so that in cross-section it extends from the outside into the closed hollow profile. The wall of the hollow profile therefore does not need to have any openings to form the channel, so that the well-known high rigidity of the closed hollow profile is maintained. At the same time, it is ensured that moisture contained in the air or moisture droplets whirled up in the area of the drainage edge cannot penetrate into the hollow profile in the area of the seal. In this embodiment, the channel can be formed from the outside in the hollow profile in a pocket-like cross-section, whereby, as in the previous embodiments, the drainage edge is at least partially covered by the channel. A corresponding design of a channel can be achieved, for example, by forming processes, in particular by rolling or rolling with suitable tools. In a further embodiment, which is based on an open hollow profile of the cross member or the cross profile, the open hollow profile has an interior and an opening cross-section or breakthrough facing the loading compartment door in the closed position, through which the drainage edge extends in the closed position, the channel being formed in the interior. Such a hollow profile can be produced on the one hand by preferably machining a closed hollow profile given as a semi-finished product

VGN 265 098 23075Nl Mu./Bz./We/Or. September 1, 1999

can be obtained, on the other hand, a large number of finished open hollow profiles can be used or these can be suitably reworked. It is preferred that the cross member and/or the cross profile are formed from a bent profile, which is available inexpensively in a large variety of cross-sectional profiles. In particular, it is envisaged that the cross member and/or the cross profile are made from an aluminum-based material or from steel. In an expedient embodiment, the channel has a lower boundary wall which has a raised edge region facing the loading compartment door in the closed position. This advantageously ensures that moisture penetrating the channel beyond the edge of the drainage edge facing the channel in the closed position, for example moisture contained in the air in the finest form or whirled up spray water which collects on the lower boundary wall of the channel, is kept away from the loading compartment door by the raised edge region. Preferably, there is a drainage option for the moisture accumulating on the lower boundary wall in the longitudinal direction of the channel, so that the liquid level never reaches the upper edge of the raised edge area. This ensures that no moisture can get into the gap below the drainage edge between the opposite wall of the cross member or the cross profile and the inner wall of the loading compartment door. A drainage option for the moisture can be provided, for example, by drainage openings or pipes that are provided on the lateral end faces of the channel. A corresponding protective effect can also be achieved by the lower boundary wall having a flat wall area that slopes towards the loading compartment door in the

VGN 265 098 23075Nl Mu./Bz./We/Or. 01.09.1 999

The channel has an upper boundary wall which has a lower edge region facing the loading compartment door in the closed position, or the upper boundary wall has a wall region which is designed to slope down towards the edge facing the loading compartment door in the closed position. Channels which have a symmetrical cross-section with respect to a central plane which is horizontal when installed can be used, but asymmetrical cross-sections also have the aforementioned advantages in terms of use. In an appropriate design, the upper and lower boundary walls of the channel are connected by means of a connecting wall at the edges facing away from the loading compartment door in the closed position. This can be advantageous both in connection with a closed hollow profile and in principle with an open hollow profile, since the dimensions of the drainage edge can be adapted to the cross-sectional shape of the channel in such a way that, in the closed position, a position of the edge of the drainage edge facing the channel or the connecting wall of the channel can be set relative to the connecting wall that is preferred in terms of the sealing effect. In the cross-section, the length of the drainage edge can be adapted to the depth of the channel in such a way that, in the closed position, there is just a small distance of a few millimeters or even a few tenths of a millimeter between the edge of the drainage edge facing the partition wall and the partition wall, so that overall a highly effective and yet contact-free and therefore wear-free labyrinth seal is provided. Although even with such a design in connection with a

VGN 265 098 23075N1 Mü./Bz./We/Or. 01.09.1 999

If an effective seal is provided by a lower boundary wall rising up from the loading area door or in conjunction with a raised edge area of the lower boundary wall facing it, an even more extensive sealing function can be achieved by a drain edge with an extended cross-section, so that the edge of the drain edge facing the connecting wall abuts against the connecting wall in the closed position. With a corresponding design, complete redundancy of the sealing effect is already achieved. Alternatively or in combination, a corresponding adjustment of the distance between the top of the drain edge and the bottom of the upper boundary wall of the channel when designing the labyrinth seal can also help to improve the sealing effect. If there is contact between the drain edge and a wall of the channel in the closed position, a drain edge with a high level of component flexibility and/or with a high level of material flexibility is recommended, so that damage is largely avoided and a seal is created that is also practically maintenance-free. In further detail, it is possible for the wall sections of the cross member or the cross profile that delimit the channel to have at least approximately the same wall thickness. In a further preferred embodiment, a groove, in particular a groove with a rectangular cross-section, is formed in an underside of the drainage edge in the area of the edge of the drainage edge facing away from the loading area door, which groove extends longitudinally parallel to the edge. In this way, a drip edge is formed on the aforementioned edge, so that moisture that reaches the underside of the drainage edge facing the channel cannot be directed towards the loading area door.

but is prevented from doing so by the groove and drips from the drip edge into the gutter to be drained away from there.

With regard to all of the embodiments described so far, it is further preferred that the loading compartment door has an inner wall facing the loading compartment in the closed position, with the edge of the drainage edge facing away from the loading compartment door and projecting into the channel in the closed position projecting beyond the inner wall in a vertical projection. In further detail, the seal on the loading compartment door can be assigned a sealing element with a sealing wall for sealing interaction with a counter-wall area that extends below an opening cross-section of the channel facing the loading compartment door in the closed position. Such a sealing element can be designed as an extruded profile made of a flexible material, in particular rubber or plastic. It is also possible for the sealing element to have a hollow cross-section. In particular, it can be provided that the sealing element is attached to the inner wall of the loading compartment door in a form-fitting and/or force-fitting manner. A positive connection can be made by a T-shaped or dovetail-like engagement of the sealing element in a correspondingly adapted recess in the inner wall of the loading compartment door. A force-locking connection can be achieved, for example, by clamping the sealing element in a gap or another recess in the loading compartment door. In addition, a material-locking fastening of the sealing element, for example by means of an adhesive layer, should also be considered. In further detail, it can be provided that the sealing element

VGN 265 098 23075M1 Mu./Bz./We/Or. September 1, 1999

element is arranged on the loading area door below, adjacent to an underside of the drainage edge. A particularly secure hold of the sealing element can be ensured by arranging the sealing element in the base of a gusset formed from the underside of the drainage edge and the inner wall of the loading area door, so that a two-sided border or support of the sealing element is produced. In any case, an additional sealing function is achieved by such a sealing element, which has a sealing wall which cooperates to seal with a counter-wall area extending below the opening cross-section of the channel. The advantage of this seal formed from the sealing element and the aforementioned counter-wall area is that it develops a preferred sealing effect with regard to substances which can be contained in the air in very fine distribution and which can float in the air due to their low weight. This applies, for example, to the ever-present air humidity or fog, as well as to various gases, dust and fine grains of sand or the like. A preferred seal is also achieved for light and heat radiation by the aforementioned seal, which is formed from the sealing element and the counter wall area. Overall, a combination is therefore advantageously achieved such that both systems of sealing the loading compartment door complement each other ideally in relation to the loading compartment structure. The seal formed from the channel and the drainage edge effectively keeps out larger particles, such as raindrops, snow or even a liquid level, which can penetrate a contacting seal if exposed for a longer period of time, as well as larger solid bodies, e.g. loose chippings, small stones or the like. Additional -

In addition to effective sealing against these substances, this also provides a protective effect for the additional sealing pairing, as described above, which is also provided if required and is formed from the sealing wall and the counter-wall area. This latter contacting sealing pairing provides a particularly reliable sealing effect due to this protection, particularly with regard to the above-mentioned substances and radiation for which sealing by means of the sealing pairing formed from the channel and the drainage edge is only possible with comparatively greater effort. In particular, it can be provided that the sealing element undergoes an elastic deformation in terms of its cross-section compared to the opening position of the loading compartment door in the closed position due to the contact or the pressure against the counter-wall area.

According to an expedient further development, the loading area door has an edge profile on the top and the run-off edge is formed in one piece on the edge profile. The aforementioned edge profile can preferably be an extruded aluminum profile that is placed on the upper edge of the door leaf and fastened to it in a suitable manner, so that the edge profile provides an upper limit for the loading area door. In a further embodiment, there is also the possibility of a further profile part being fastened to the edge profile running parallel to it and of the run-off edge being formed in one piece on this further profile part. This also makes it possible in a simple way to select the run-off edge and the edge profile from different materials adapted to the respective sub-tasks. For example, when using an aluminum edge profile, the further profile part can be made from a rubber -

VGN 265 098 23075Nl Mu./Bz./We/Or. 01.09.1 999

•&Igr;&ogr;

or plastic material that allows the desired flexibility depending on the design of the drainage edge, or it can be made of an aluminum-based material. The additional profile part can be attached to the edge profile in a force-fitting and/or form-fitting and/or material-fitting manner. In an alternative design, the drainage edge can also be molded onto the sealing element above its sealing wall or formed in one piece with the sealing element. It can be advantageous if a web-like extension is additionally molded onto the sealing element attached to the inner wall of the loading area door, which extension covers an area of the upper front side of the loading area door and is also attached to it in a force-fitting and/or form-fitting and/or material-fitting manner.

According to a further preferred embodiment, it is provided that a second channel is formed in an upper wall of the cross member and/or the cross profile in the installed position. In particular, this can be implemented on a closed hollow profile as explained above, whereby the channel can be formed into the walls from the outside in the manner of a pocket. It is also possible for the cross member and/or the cross profile to have a rectangular cross section with two walls perpendicular to one another and enclosing an edge, whereby a channel is formed on the first and second walls in the edge area facing away from the edge. In addition, different cross-sectional shapes of the cross member and/or the cross profile are of course also conceivable, for example trapezoidal, triangular, polygonal or round cross sections. According to a further preferred embodiment, it can be provided that the cross profile has a

VGN 265 098 23075N1 Mü./Bz./We/Or. September 1, 1999

forms a cross-sectional area that is open on one side and whose inner contour is adapted to an outer contour of the cross member. The cross-sectional area that is open on one side can be bordered by an angle profile, and the cross profile can be provided with receiving grooves that run in its longitudinal direction, are oriented parallel to one another and are vertically spaced apart in the installed position, in which the angle profile can be held in a form-fitting manner. This advantageously achieves height adjustment of the angle profile, so that the inner contour of the cross profile can be flexibly adapted to the outer contours of various cross members and thus a quick and resilient attachment of the cross profile to the cross member is possible. The attachment can be carried out, for example, in such a way that the cross profile with the cross-sectional area that is open on one side is pushed onto the cross member so that the opening cross section provided for this faces the channel formed in the cross profile of the loading compartment door in the closed position. In this arrangement, the cross-section can be attached to the cross-member either firmly or detachably using the connection techniques commonly used in vehicle construction, e.g. by screwing, riveting, welding, gluing or in another suitable way. This makes it possible, in a simple and economical way, to retrofit existing loading space structures with conventional cross-members integrated into them with a channel by installing a corresponding cross-section, so that in conjunction with a door-side drainage edge, the advantages according to the invention are achieved.

In a further preferred embodiment of the loading space structure, it is possible to have a profiled line on the upper side of the cross member or the cross profile.

ste which, in the installed position, has a web which runs vertically in the longitudinal direction of the cross member or cross profile and whose upper edge region is curved in the forward direction of travel of the truck. This advantageously prevents accumulated moisture, snow or the like from overflowing over the rear roof edge of the loading space structure, particularly when the truck starts moving after a long standstill. The vertically running web can be further developed in such a way that a strip is formed on a vertical wall facing away from the loading space, which strip is designed to rise towards its free edge region running in its longitudinal direction. In particular, it can be provided that the edge of the strip facing away from the vertical web protrudes in a vertical projection over the outer wall of the loading space door, so that overall the loading space door and, if applicable, its hinge and locking elements are roofed over. Such a strip covering the loading area door forms a drainage channel that is open at the top and drains moisture coming from above. The vertical web and the strip molded onto it can be made from a plastic or rubber material, for example, or from aluminum, and are preferably attached in a form-fitting manner to an upper wall of the cross member and/or the cross profile in the installed position.

In addition to the above statements, it is also possible for the cross member and/or the cross profile to be made of a plastic material, in particular a hard plastic.

The invention further relates to a loading space structure, in particular of a truck, with a frame and with a loading space door which can be pivoted about an axis of rotation and on which a locking device is formed, wherein the locking device has a rotatably mounted transmission rod with an extension protruding therefrom for locking in a receptacle screwed to the frame, wherein the loading space structure has a wall with a recess in the region of the receptacle and a holding element is provided on the side of the wall facing away from the receptacle, to which the receptacle is fastened with a threaded pin passing through the recess.

A corresponding loading space structure is known from EP 0 698 515 A2, which is fully incorporated into the present application, also for the purpose of incorporating features thereof into the claims of the present application. In the known loading space structure, it is also apparent that the holding element is designed as a counter bearing protruding from the inside of the wall. In order to further develop such a loading space structure in a manner that is advantageous for use, the invention proposes that the wall is formed on a hollow profile and that the holding element is accommodated in the interior of the hollow profile. On the one hand, this ensures that the holding element does not point freely from the inside of the wall into the interior of the loading space structure, which, in addition to better utilization of the loading space, also brings with it the advantages of a more visually appealing solution, a lower risk of injury and security against loss of the holding element. In a preferred development, it is provided that the recess is designed as a slot extending in the longitudinal direction of the hollow profile, the slot

VGN 265 098 23075N1 Mu./Bz./We/Or. September 1, 1999

width is adapted to the diameter of the threaded pin. This is understood to mean a slot width with such an excess compared to the diameter of the threaded pin that the latter can be pushed through the slot without difficulty, while at the same time a negligible amount of play in the direction of the walls delimiting the slot is achieved with respect to the diameter of the threaded pin. This design advantageously achieves a high degree of flexibility with regard to the fastening location of the holder on the loading space structure, with subsequent changes to the fastening location also being possible. During assembly, the holder can initially be loosely connected to the threaded pin guided through the recess, with a certain amount of play in the longitudinal direction of the threaded pin still being possible. If the recess is designed as a slot, the holder can then be moved along the slot to the desired fastening position. Then - as with a differently designed recess - the threaded pin is screwed further into a threaded hole in the holder and/or the holding element until, due to the reduced distance between the holder and the holding element, a clamping with the wall and thus a fastening of the holder is achieved. In connection with a slot-like recess, it is particularly intended that the slot extends over the entire length of the hollow profile. It can also be provided that the holder is fastened with at least two threaded pins that extend through one or at least two adjacent slots. This not only maintains the variability of the fastening location of the holder, but at the same time advantageously prevents the holder from being accidentally twisted even if the holder is only loosely fastened.

avoided. It is also preferred that the threaded pin is formed on a screw, that the receptacle has a recess adapted to the diameter of the threaded pin and a support surface for the screw head surrounding the recess, and that the holding element contains a nut thread matched to the threaded pin. The holding element can preferably be a profile body which has an outer contour in cross section which is matched to an inner contour of the hollow profile, so that an alignment of the holding element is achieved by mutual contact. For example, a rectangular profile with only slightly smaller dimensions can be held in a hollow profile whose interior has a rectangular cross section. On the other hand, the wall of the hollow profile can have a projection facing the holding element which is encompassed by the holding element in a pot-like cross section, i.e. in a trough-like manner when viewed three-dimensionally. In any case, such an alignment of the holding element makes the assembly of the holder easier, since the nut thread of the holding element inserted into the hollow profile, which is matched to the threaded pin, can be held in the desired position in cross-section before the holder is attached, i.e. at least partially overlapping with the recess. Alternatively, it can be provided that the threaded pin with the holding element as a head forms a screw and that the holder has a nut thread matched to the threaded pin or that instead of this nut thread a recess is provided in the holder and a separate counter element with an internal thread, e.g. a screw nut. In this design, the screw is first inserted into the hollow profile during assembly, for example starting from a free front end.

VGN 265 098 23075N1 Mü./Bz./We/Or. 01.09. 1999

so that the head of the screw points into the interior of the hollow profile as a holding element. If the slot has an open end, the receptacle can already be loosely connected to it when the screw is inserted. The screw can then be moved - if necessary with the receptacle - into the desired fastening position, whereupon the screw is screwed into the nut thread until the desired fastening of the receptacle is achieved. Alternatively or in combination with the aforementioned features, one or both of the opposing boundary walls of the slot can have grooves running in the longitudinal direction of the hollow profile or a cross-sectional profile in which a filler profile closing the emergency cross-section is held in a form-fitting manner perpendicular to the longitudinal direction of the hollow profile. The filler profiles can be dimensioned and arranged in such a way that, in conjunction with one or more threaded pins, the slot is completely or almost completely covered. This creates an attractive appearance and functional protection against the ingress of moisture, dirt or the like. Furthermore, it is preferred that the hollow profile and/or the filler profile and/or the holding element are extruded profiles, for example based on aluminum, made of steel, a plastic material or another suitable material, whereby the aforementioned components can also be made of different materials from one another. A previously described hollow profile can also have several hollow chambers in cross section and/or show one or more of the further features as described in the present application with reference to cross profiles, cross beams and support profiles provided on a loading space structure.

The invention also relates to a loading space structure, in particular of a truck, with a frame formed from support profiles and with side and front walls as well as with a roof-side wall, of which at least one wall has a covering with a tarpaulin which is fastened to the frame.

In order to further develop such a known loading space structure in a manner that is advantageous for use, the invention proposes that a groove is formed on a support profile along an edge of the tarpaulin covering in a surface of the support profile, which has a hollow chamber in a cross-section perpendicular to the longitudinal direction and a passage opening that is tapered in cross-section, and that an insert element adapted to the cross-sectional contour of the hollow chamber is accommodated in the groove, which is surrounded by the tarpaulin in a loop-like cross-section. The insert element is preferably a cord or a rope, i.e. an elongated body that is flexible at least transversely to the longitudinal direction. Preferably, a plastic cord or a cord made of an animal material can be used, but alternatively the use of a steel cord, in particular a steel cord with a plastic coating, is also conceivable. Because the insert element is looped around the tarpaulin, it is advantageous to attach the tarpaulin to the carrier profile using only the insert element, i.e. with just one single fastening element. In addition, the tarpaulin can be attached in a way that is easy to remove and saves space. Another advantageous effect of an insert element that is looped around the tarpaulin, which is also known as

VGN 265 098 23075N1 Mü./Bz./We/Or. 01.09.1 999

v«, -m -99

The advantage of this method, which is also known as a piping, is that the tarpaulin has an edge reinforcement which, in addition to protecting the edge from damage, also makes it easier to attach the tarpaulin. The attachment process can be carried out by first inserting the tarpaulin in a loop-like cross-section into the hollow chamber-shaped area of the groove and then pushing or pulling the insert element into it from the side. Alternatively, the tarpaulin can first be placed in a loop-like cross-section around the insert element and then pushing or pulling it into the groove together with it. The tarpaulin can, for example, have a prepared loop cross-section along its edge, for example a folded over and sewn or glued edge area, but on the other hand a two-layer covering can easily be created using a simple tarpaulin even without a corresponding edge. With regard to the carrier profile, the hollow chamber can, in an expedient embodiment, have a substantially circular cross-sectional contour with an inner diameter and the insert element can have a round, preferably also substantially circular, cross-section perpendicular to its longitudinal extension with an outer diameter, wherein the diameter difference between the inner and outer diameter preferably slightly exceeds twice the material thickness of the tarpaulin. In this case, an excess of the diameter difference compared to twice the material thickness is preferred, at which the insert element and the tarpaulin can still be easily inserted into the groove with at the same time minimized lateral movement play. It is also preferred that the clear width of the passage opening corresponds to approximately half the inner diameter. It is also preferred that the carrier profile as

VGN 265 098 23075Nl Mü./Bz./We/Or. 01.09.1 999

·

Hollow profile is formed in which the groove is formed by an area of an outer wall that is molded into the interior of the hollow profile. In this sense, the groove is formed in the hollow profile in a pocket-like cross-section. It is also possible for a web to protrude from the wall surrounding the groove inside the hollow profile, facing away from the groove, the other end of which is connected to a wall of the hollow profile that is arranged at a distance from the wall containing the groove. This measure provides support or stiffening of the wall immediately surrounding the groove, which is particularly advantageous when there is great tensile stress within the tarpaulin and when the wall thickness of the carrier profile is small. It is also preferred that a contact surface for the tarpaulin is formed on an outer surface of the carrier profile that borders the passage opening, which provides an attractive appearance. Furthermore, the wall in the area between the contact surface and the hollow chamber can form a projection with a free end that points in the direction of the passage opening. While the insert element is held in the groove by the passage opening tapered in cross-section compared to the hollow chamber, with regard to fixing the position of the insert element in the longitudinal direction, it is envisaged that the insert element has an axial projection relative to the carrier profile at one or both front ends and a radial projection with respect to its longitudinal axis, to which a longitudinal section of the insert element is connected, which is connected - preferably detachably - to the loading space structure. The idea is to have a connection through which at least a clear fixing in the longitudinal direction of the insert element is provided at the fastening end of the insert element. For this purpose,

VGN 265 098 23075N1 Mü./Bz./We/Or. 01.09.1 999

a fastening element, for example an eyelet, a hook or another part commonly used for this purpose, to which the insert element, preferably a cord or a rope, is to be fastened, for example by means of a knot with a loop or the like, is provided on the loading space structure. At the same time, this also ensures that the insert element is axially positioned in the region of the support profile. It is preferably provided that the projection is formed by a bend in the insert element in its end region. In an expedient further development, a closure plate can be fastened to a front end of the hollow profile. If the front end of the insert element projects beyond the front end of the hollow profile, the closure plate can have a recess which is adapted in terms of its position and dimensions to the insert element accommodated in the hollow profile, so that the insert element projects through the recess. Furthermore, the closure plate can have an area of reduced wall thickness adjacent to the recess, which is adapted in terms of its position and dimensions to the radial projection, for example to a bend, of the insert element and through which a trough is formed in the surface facing away from the carrier profile. The depth of the trough can be dimensioned such that, starting from the recess, there is a continuously increasing projection of the radial projection with respect to the surface, which outside the trough in a subsequent longitudinal section can correspond approximately to a cross-sectional dimension of the insert element. This is advantageous if the surface of the closure plate is itself covered with a tarpaulin, for example, since the embedding of the projection in the trough and the gradual advance of the insert element prevent damage.

VGN 265 098 23075Nl Mu./Bz./We/Or. September 1, 1999

the tarpaulin is avoided. It is also possible for the carrier profile to have one or more clearances in the cross-section to accommodate one or more self-tapping fastening screws of the closure plate. In a further preferred embodiment of the loading space structure, the roof-side wall is covered with the tarpaulin, the hollow profile being arranged above a loading space door, the passage opening in the hollow profile pointing upwards and the free end of the projection of the wall pointing away from the loading space.

It is also possible that the support profile is an extruded profile, in particular based on aluminium, made of steel, a plastic or another suitable material and/or that the support profile has one or more features which are described in connection with the cross profiles and cross beams explained in this application.

The invention further relates to a loading space structure, in particular for a truck, with a frame formed from support profiles, in which a support profile is arranged in the region of the upper edge of a loading space door for sealing interaction with the loading space door, and with a tarpaulin roof which has an adjustment device for adjusting the position of an edge profile of the tarpaulin roof facing the loading space door in the closed position.

In order to further develop such a known loading space structure, the invention proposes that the carrier profile and the edge profile are formed in one piece. This ensures that the

Adjustment device simultaneously allows the position of the support profile sealing against the loading space door to be adjusted. In particular, the support profile can be moved by the adjustment device into an open position of the tarpaulin roof, so that when the loading space door is open at the same time, a continuous opening of the loading space is created. Furthermore, a compact design is achieved according to the invention. In an expedient embodiment, the support profile and the edge profile can be designed as a single piece as a hollow profile. Furthermore, the hollow profile can have a wall facing the loading space, to which an actuating element of the adjustment device is attached with a movable end by a screw connection. The movable end can have a base plate which is attached to the wall of the hollow profile by the screw connection. Preferably, it is provided that the wall and the base plate have openings, wherein in the assembly position the associated openings are aligned and a screw is inserted through them and secured inside the hollow profile with a counter element. The counter element can be an extruded profile with a rectangular or other suitable cross-section, in which a nut thread is provided that is matched to the screw. It is preferred that the counter element, when assembled, rests with a broad side on an inner surface of the wall of the hollow profile. According to a suitable development, a web can be formed on a wall inside the hollow profile, through which a contact surface is provided in cross-section for positioning or supporting the counter element. This measure also makes assembly easier, since the counter element can be held in a desired position before screwing, in which at least an overlap between

VGN 265 098 23075N1 Mü./Bz./We/Or. 01.09.1 999

the cross-section of a nut thread and an opening. In addition, reproducible assembly and/or additional force transmission between the adjustment device and the edge profile can be achieved by providing corresponding projections and depressions on the outer surface of the wall and on the surface of the base plate adjacent to the outer surface. Furthermore, it is envisaged that the hollow profile can have several hollow chambers in cross-section. It is also possible for a reinforcing profile to be inserted in a hollow chamber, the outer contour of which is geometrically adapted to the inner contour of the hollow chamber. In view of the above statements, a variant can also be advantageous in which the opening in the wall of the hollow profile is designed as a slot opening which can extend in the longitudinal direction of the hollow profile over its entire length. The edge profile formed in one piece with the support profile can be an extruded profile, in particular based on aluminum, made of steel, plastic or another suitable material and/or have one or more of the features as described in the present application with reference to the proposed cross profiles, cross beams and support profiles.

Figure 1 shows a rear plan view of a loading space structure 1 of a truck according to the invention. The loading space structure 1 has loading space doors 2 arranged in two wings on the rear end. Each loading space door is pivotably mounted on the loading space structure 1 by means of hinges 4 through a vertical axis of rotation 3. Furthermore, locking devices 5 are provided for locking the loading space doors 2 in their closed position. The locking devices 5 have actuating elements 6, furthermore transmission elements 7 designed as pivot rods in the example shown, as well as locking elements 8 fastened to them and receptacles 9 fastened to the rear wall of the loading space structure which receive these when locked. Each of the loading space doors 2 shown has a seal 10 for sealing interaction with a counter wall 11 of the loading space structure 1. The seal 10 is assigned a drainage edge 12 (see also Fig. 2) which, starting from an upper edge region 13 of the loading compartment door 2 in the illustrated closed position, extends in the direction of the loading compartment into a region bordered by the counter wall 11.

VGN 265 098 23075N1 Mu./Bz./We/Or. September 1, 1999

, which extends into the groove facing the loading compartment door 2 in the closed position. While the loading compartment doors 2 shown in Figure 1 are, according to what has been said above, the rear loading compartment doors 2 of a loading compartment structure 1 according to the invention, it can of course also be provided that side loading compartment doors arranged on the side walls 15 of the loading compartment structure 1 are sealed off from the rest of the loading compartment structure 1 in the manner described above and below.

In Figure 2, according to the section line II-II in Figure 1, it is shown in further detail that the drainage edge 12 in the embodiment shown extends from the upper edge region 13 of the loading compartment door 2, rising in the direction of the loading compartment. As can also be seen from the combination of Figures 1 and 2, the channel 14 extends in its longitudinal direction parallel to the loading compartment door 2 when the loading compartment door is in the closed position. The loading compartment structure shown in Figure 2 also has a cross member 16 in which the channel 14 is formed in an arrangement facing the loading compartment door 2 in the closed position. The cross member 16 is attached with its end cross-sectional areas to the inside of the side walls 15 of the loading compartment structure 1, without this being shown in more detail. In the embodiment shown in Figure 2, the cross member 16 has a closed hollow profile in cross section, with the channel 14 being formed from the outside into the closed hollow profile in a pocket-like manner, so that in cross section it extends from the outside into the closed hollow profile. The channel has a lower boundary wall 17 which is designed to rise in the direction of the edge 18 facing the loading compartment door 2 in the closed position. Furthermore, the

Channel 14 has an upper boundary wall 19 which slopes towards the edge 20 facing the loading compartment door in the closed position, so that the channel 14 has a symmetrical cross-section with respect to a horizontal centre plane x-x. In further detail, it is shown that the upper 19 and lower 17 boundary walls of the channel 14 are connected at the edges 21, 22 facing away from the loading compartment door 2 in the closed position by means of a connecting wall 23. In the embodiment of Figure 2, in the closed position of the loading compartment door 2 shown, the edge 24 facing away from the loading compartment door 2 is spaced from the connecting wall 2 of the channel 14 by the distance a, which is not shown to scale here for easier understanding, so that the combination of the channel with the drainage edge 12 creates a gap or labyrinth seal. As is further shown, the loading compartment door 2 has an inner wall 25 facing the loading compartment in the closed position, with the edge 24 of the run-off edge 12 facing away from the loading compartment door 2 projecting significantly beyond the inner wall 25 in a vertical projection. According to Figure 2, the seal 10 is also assigned a sealing element 26 with a sealing wall 27 which is positively attached to the inner wall 25 of the loading compartment door 2 for the sealing interaction of the sealing wall 27 with a counter wall area 28 which extends below an opening cross section 29 of the channel 14 facing the loading compartment door 2 in the closed position. As can be clearly seen, in the arrangement shown, the sealing surface between the sealing wall 27 and the counter wall area 28 is covered by the run-off edge 12 which projects beyond the inner wall 25 in a vertical projection. In the arrangement shown in Figure

VGN 265 098 23075N1 Mü./Bz./We/Or. 01.09.1 999

In the embodiment shown in Figure 2, the sealing element 26 is designed as an extruded profile made of a flexible material, in this case rubber, and has a closed hollow cross-section with cavities 30. In the example shown, the sealing element 26 is positively attached to the inner wall 25 of the loading area door 2; in particular, this is achieved by the engagement of a T-shaped extension of the sealing element 26 in a correspondingly geometrically adapted recess in the inner wall 25. According to Figure 2, it is further provided that the drainage edge 12 has a bottom side 31 and that the sealing element 26 is arranged adjacent to the bottom side 31 below. In this way, the sealing element 26 is supported on two sides against the run-off edge 12 and the inner wall 25. In the exemplary embodiment shown, it is also provided that a groove 58 with a rectangular cross-section is formed in the underside 31 of the run-off edge 12 in the area of the edge 24 facing away from the loading area door 2, which groove extends in the longitudinal direction parallel to the edge 24. In further detail, it is provided that the loading area door 2 has an edge profile 32 on the upper side, in the example shown an extruded aluminum profile, and that the run-off edge 12 is formed in one piece on the edge profile 32. Figure 2 also shows that the cross member has a second channel 33 in a wall that is upper in the installed position. In the exemplary embodiment shown, this is designed with the same cross-sectional shape as the channel 14, but rotated by 90°. The channel 3 3 shown can serve as an additional collecting container or drain for moisture, e.g. rain or snow. If necessary, it can also be replaced by a piping (not shown in the drawing), ie by a

VGN 265 098 23075N1 Mu./Bz./We/Or. 01.09.1 999

&iacgr;&ogr;·

cross-section 29 of the channel 33. Overall, the cross member 16 has a rectangular cross-section with two walls 35, 36 which are perpendicular to one another and enclose an edge 34, with a channel 33, 14 being formed on the first and second walls 35, 36 in the edge region 37, 38 facing away from the edge 34.

The embodiment shown in Figure 3 differs from that shown in Figure 2 in that the cross member 16 is installed in a vertical arrangement rather than a horizontal arrangement with respect to its rectangular cross-sectional shape. For this purpose, a cross member 16 with the identical cross-section shown in Figure 2 can be provided, since the cross member 16 shown in Figure 2 can be transferred into the position shown in Figure 3 by suitable rotary movements. As can be seen from this, instead of the channel, the channel 33 faces the loading compartment door 2 in the closed position. Accordingly, the drainage edge 12 extends from an upper edge region 13 of the loading compartment 2 in the closed position, rising towards the loading compartment into the channel 33. The counter wall 11 bordering the channel 33, against which the loading compartment door 2 is sealed, is formed by the wall 35 (including the edge area 37) of the cross member 16. Compared to the variant shown in Figure 2, Figure 3 offers the possibility of a full-surface support or fastening of the locking elements 8 to the counter wall 11. For further details on this design and for further details concerning the construction of the loading compartment door 2, reference is made to EP 0 69 8 515 A2, which has already been mentioned as prior art and which is fully incorporated into the present application.

VGN 265 098 23075Nl Mü./Bz./We/Or. September 1, 1999

lently included, also for the purpose of incorporating features in claims of the present application. For better clarity, in Figure 3 and in the following figures only those reference symbols are entered which are helpful in explaining deviations from the embodiment shown in Figure 2.

Figure 4 shows a further exemplary embodiment of a loading space structure according to the invention in a corresponding partial section. In contrast to the embodiment shown in Figure 2, a different cross-sectional shape of the channels 14 and 33 is selected in Figure 4. With regard to the channel 14, it is provided that this has a lower boundary wall 39 which has a raised edge region 40 facing the loading space door 2 in the closed position. The channel 33 has a similar cross-sectional shape when aligned accordingly. As indicated in dashed lines, this makes it possible for the cross member 16 to be installed alternatively in an arrangement that is stationary with respect to its rectangular cross-section, with the channel 33 in this arrangement taking the place of the channel 14, the wall 41 taking the place of the lower boundary wall 39 and the edge region 42 taking the place of the raised edge region 40.

Figure 5 shows a further expedient embodiment of a loading space structure according to the invention in a corresponding partial section. According to this, a profile part 43 is attached to the edge profile 3 2 of the loading space door 2, running parallel thereto, and the run-off edge 12 is formed on the profile part 43, in the example shown, formed in one piece.

VGN 265 098 23075Nl Mü./Bz./We/Or. September 1, 1999

As shown in further detail, the profile part 43 is attached to the upper end face of the edge profile 32 by pressing a web 44 of the edge profile 43 into a recess facing it in the edge profile 32. The different hatching clearly shows that the profile part 43 with the drainage edge 12 formed on it is made of a different material than the edge profile 32. While in the example shown the edge profile is an extruded aluminum profile, the profile part 43 with the drainage edge 12 is made of a flexible plastic material.

Figure 6 shows an alternative embodiment in which the run-off edge 12 above the sealing wall 27 of the sealing element 26 is formed in one piece with the sealing element 26. In the embodiment shown, the sealing element 26 with the run-off edge 12 is made of an elastic rubber material. As is also shown, the sealing element 26 is positively secured both to the inner wall 25 and to the upper end wall 45. This is achieved in each case by a positive engagement of a T-shaped extension formed on the sealing element 26 in a geometrically adapted recess in the respective surfaces of the loading area door 2.

In Figure 7, a further preferred embodiment of a loading space structure according to the invention is shown in a partial section, wherein the loading space structure 1 has a cross-section 46 connected to the cross member 16 and the channel 14 is formed in the cross-section 46. In the embodiment shown in Figure 7, this is achieved in that the cross-section 46 has an open cross-section in its lower cross-sectional area in the installed position.

Hollow profile. The channel has a lower boundary wall 17 which has a raised edge region 40 facing the loading compartment door 2 in the closed position. The channel 14 is also delimited by an upper boundary wall 19. It is further provided that the upper and lower boundary walls 17, 19 of the channel 14 are connected at the edges 21, 22 facing away from the loading compartment door 2 in the closed position by means of a connecting wall 23. From what has been said above it is clear that the open hollow profile has an interior in the lower region of the cross profile 46 and that the channel is formed in the interior. The open hollow profile also has an opening cross section 29 or breakthrough facing the loading compartment door 2 in the closed position, through which the drainage edge 12 extends in the closed position. In further detail, the cross-section 46 has a cross-sectional area that is open on one side in Figure 7 towards the left edge of the drawing, the inner contour of which is adapted to the outer contour of the cross member 16. It is provided that the cross-sectional area that is open on one side is bordered by an angle profile 47 and that vertically spaced receiving grooves 48 are provided on the cross-section 46 that run in the longitudinal direction of the cross-section and are oriented parallel to one another, in which the angle profile 47 can be held in a form-fitting manner. In Figure 7, solid lines show a geometric adaptation of the cross-sectional area that is open on one side to a cross member 16 with an approximately square cross-section by inserting the angle profile 47 into the lower of two provided receiving grooves 48 or fastening it therein. An alternative arrangement is indicated with broken lines in which the angle profile 47' is inserted into the upper of the two receiving grooves 48, so that a geometric adaptation

to a cross member 16 with a rectangular cross section in an arrangement that is upright with respect to the rectangular cross section. In the embodiment according to Figure 7, a profile strip 49 is also attached to the top of the cross profile 46, which has a web 50 that is vertical in the installed position and runs in the longitudinal direction of the cross member 16 or the cross profile 46, the upper edge region 51 of which is curved in the forward direction of travel of the truck. In addition, a strip 53 is formed on the vertically running web 50 on one of the vertical walls 52 facing away from the loading area, which is designed to rise towards its free edge region 54 running in its longitudinal direction. As is also shown, the cross profile 46 and the angle profile 47 are attached to the cross member 16 with a weld seam 55, although the attachment can also be implemented in other ways, for example by riveting, screwing, gluing or the like.

Figure 8 shows a further embodiment of a loading space structure according to the invention in a partial section, wherein the channel is accommodated in a cross-section 46, which is designed as a hollow profile with an S-shaped cross-section. In the example shown, the cross-section 46 is a folded profile, which has a shape in its upper wall area through which a V-shaped collecting and draining channel 57 for moisture, such as rainwater and snow, is formed. The cross-section 46 is connected to the cross member 16 at two wall areas located far apart from one another with a weld seam 55.

Figure 9 shows a further expedient embodiment of the loading space structure, in which the channel 14 is formed in the lower cross-sectional area of a cross-section 46.

VGN 265 098 23075Nl Mu./Bz./We/Or. September 1, 1999

is det, whereby an open hollow profile is provided as the cross profile 46. While the lower boundary wall 17 with the raised edge region 18 and the connecting wall 23 are formed by the cross profile 46, the upper boundary wall 19 is part of the cross member 16, which is connected to the cross profile 46 by weld seams 55. Furthermore, it is provided that the cross profile 46 has a horizontally extending end region 56 in its upper cross-sectional region, by means of which a roof is provided for the loading space door 2.

Figures 10 and 11 show further expedient embodiments of the loading space structure according to the invention, wherein the channel 14 is accommodated in transverse profiles 46 of different cross-sectional shape.

Fig. 12 shows a rear view of the upper edge region of another preferred embodiment of a loading space structure 59, with two vertically extending cuts being made for a more compact representation. As is clear in connection with Fig. 13, which shows a partial section in the longitudinal direction along the section line XIII-XIII of Fig. 12, and in connection with the partial sections further marked in Fig. 12, the loading space structure 59 has a support profile 60 designed as a hollow profile on its rear upper edge region, which also embodies the edge profile. The exemplary embodiment of a loading space structure 59 shown is one of a truck, but a corresponding design would also be conceivable, for example, for a trailer of a truck, a container or the like. It is assumed here merely by way of example that the support profile 60

VGN 265 098 23075Nl Mu./Bz./We/Or. September 1, 1999

with its longitudinal direction extending transversely to the direction of travel of the truck.

Figure 14 shows a partial section of the loading space structure according to Figure 12 along the section line XIV-XIV, from which further details of the cross-section of the support profile 52 can be seen and which also shows attachments that are described below. Figure 15 also shows a loading space door 2, which cooperates with the support profile 60 to form a seal when closed. The loading space door 2 is also indicated in the two edge areas of Figure 13, but in the middle area of the image it is not shown - as in Figure 12 and the associated sections for a better overview. Figure 14 therefore relates to an open state of the loading space door 2, while Figure 15 describes a closed state. It is initially clear, but this is not necessary with regard to the features described below, that the support profile 60 also has a channel 14 and the loading area door 2 has a drainage edge 12 extending into the channel 14 for sealing interaction. With regard to these and the features described in connection therewith, which can also be implemented individually or in combination in the support profile 60, reference is made to the preceding explanations.

A locking device 62 is formed on the loading compartment door 2, which can be pivoted about a pivot axis 61 (see Fig. 13). This has a rotatably mounted transmission rod 63 with an extension 64 protruding therefrom for locking with a receptacle 65 of the loading compartment structure. The receptacle 65 is attached to a wall 66 of the support profile 60, which is also part of a frame of the loading compartment structure 59. In the area

VGN 265 098 23075Nl Mü./Bz./We/Or. September 1, 1999

the receptacle 65, the wall 66 has a recess 67, and on the side of the wall 66 facing away from the receptacle 65, a holding element 68 is provided, to which the receptacle 65 is fastened by a threaded pin 69 passing through the recess 67, wherein the holding element 68 is accommodated in a hollow chamber 70 on the receptacle side in the interior of the support profile 60 designed as a hollow profile. It is further provided that the threaded pin 69 is designed as a component of a screw 71 for fastening the receptacle 65, that the receptacle 65 has a recess 72 adapted to the diameter of the threaded pin 69 and a support surface 73 surrounding the recess 72 for the screw head 74. The holding element 68 also contains a nut thread 75 that matches the threaded pin 69. The recess 67 is designed as a slot that extends in the longitudinal direction of the carrier profile 60 or the hollow profile, the slot width B of which is slightly larger in cross-section than the diameter of the threaded pin 69, so that a centering effect is created in the cross-section. It is also provided that the slot extends over the entire length of the carrier profile 60, which is designed as a hollow profile. Each of the receptacles 65 provided is attached to the wall 66 of the carrier profile 60 with two threaded pins, as can be seen in connection with Figures 12 and 13. According to the representation of Figures 14 and 15, it is further provided that an outer contour 76 of the holding element 68 is matched in a cross section to an inner contour 77 of the receiving-side hollow chamber 70, so that an alignment of the holding element 68 is achieved by mutual contact. For this purpose, in the embodiment shown, the wall 66 of the hollow profile has a projection 78 facing the holding element 68, which is protruding from the holding

VGN 265 098 23075Nl Mü./Bz./We/Or. 01.09. 1999

element 68 is surrounded in a pot-like manner in cross-section. It is also shown that the recess or slot has opposing boundary walls with grooves 80 running therein in the longitudinal direction of the hollow profile. As can be seen in conjunction with Fig. 16, a filler profile 81 closing the slot cross-section is held in the grooves 80 in a form-fitting manner perpendicular to the longitudinal direction of the hollow profile. In the exemplary embodiment shown, the holding element 68 and the filler profile 81 are made as extruded profiles from an aluminum material, the longitudinal axis of the profile extending perpendicular to the plane of the drawing in Figures 14 to 16. Alternatively, however, there is also the possibility that the holding element 68 is made from steel. The filler profile 81 is by no means limited to being made from an aluminum material either, but can alternatively be made from a plastic material, preferably from a hard plastic. With regard to further details of a preferred embodiment of the locking device 62, reference is also made to EP 0 69 8 515 A2, which is fully incorporated into the present application, also for the purpose of incorporating features therefrom into claims of the present application. The carrier profile 60 according to Fig. 16 differs from that shown in Fig. 15 in that the webs 108, 109 have a different shape, the function of which will be discussed later.

Fig. 17 shows a partial section of the loading space structure according to Fig. 12 along the section line XVII-XVII. A tarpaulin 82 is shown therein, which forms a covering of a roof-side wall 8 3 and which is attached to the support profile 60, which is part of a frame of the loading space structure 59. For this purpose, in the illustrated

VGN 265 098 23075Nl Mu./Bz./We/Or. September 1, 1999

In the exemplary embodiment shown, a groove 85 is formed along the rear edge of the tarpaulin covering in a surface 84 of the carrier profile 60, which has a hollow chamber 86 in a cross-section perpendicular to the longitudinal direction and a through opening 87 which is tapered in cross-section compared to this (see also Fig. 16). An insert element 88 which is adapted to the cross-sectional contour of the hollow chamber 86 on the tarpaulin side and which is surrounded by the tarpaulin 82 in a loop-like cross-section is accommodated in the groove 85. The hollow chamber 86 has an essentially circular cross-sectional contour with an inner diameter D, and the insert element is a cord with an outer diameter d, the diameter difference D-d between the inner and outer diameters slightly exceeding twice the material thickness of the tarpaulin 82. As an example, it is provided that the clear width L of the through opening corresponds to approximately half the inner diameter D. In the embodiment shown, the carrier profile 60 is designed as a hollow profile in which the groove 85 is formed in a pocket-like cross-section by an area 89 of the outer wall formed towards the interior of the hollow profile. A web 90 protrudes from the wall 89 surrounding the groove 85 inside the hollow profile on the side facing away from the groove, the other end of which is connected to a wall 91 of the hollow profile, which is arranged at a distance from the wall 9 2 having the groove 85. Furthermore, a contact surface for the tarpaulin 82 is formed on an outer surface 93 of the carrier profile 60 adjacent to the passage opening 87. In further detail, the wall 92 in the area between the contact surface 9 3 and the hollow chamber 86 forms a projection 94 with a free end 95 which points in the direction of the passage opening 87 in cross-section. While the passage opening 87 in the embodiment shown as

VGN 265 098 23075Nl Mu./Bz./We/Or. September 1, 1999

Since the carrier profile 60 designed as a hollow profile points upwards, the free end 9 5 of the projection 94 of the wall (92) is directed away from the loading space. With regard to the fixing of the holding profile in its longitudinal direction selected in the exemplary embodiment described, reference is made at this point to the later description in connection with Figures 19 to 21.

The support profile 60 shown in Fig. 17 is part of a frame of the loading space structure 59, which, as previously stated, has a tarpaulin roof. In conjunction with Fig. 15, it becomes clear that the proposed support profile 60 has a dual function in that it cooperates with the loading space door 2 in a sealing manner when it is closed and, with reference to the tarpaulin fixation described above, at the same time forms an edge profile of the tarpaulin roof. According to Fig. 17, the support profile 60 also fulfills a third function in this context in that the possibility of adjusting the position within the plane of the drawing is provided by an adjustment device for the tarpaulin roof - not fully shown in the drawing. For this purpose, a known adjustment device for tarpaulin roofs of loading space structures can be provided with an actuating element 96 which carries out a translation and/or pivoting movement with a movable end so that the desired opening of the tarpaulin roof is achieved depending on the actuating position. The carrier profile 60, designed as a hollow profile, has a wall 97 facing the loading space, to which the actuating element 96 of the adjustment device is fastened with its movable end by a screw connection 98 in the illustrated embodiment. In the illustrated embodiment, the movable end of the actuating element 96 has a base plate 99,

which is attached to the wall 97 of the hollow profile by the screw connection 98. The wall 97 and the base plate 99 have openings 100, 101 which are aligned in the assembly position shown. A screw 102 is pushed through the openings 100, 101 and secured inside the hollow profile with a counter element 103. The counter element 103 is a flat extruded profile with a rectangular cross-section in which a nut thread 104 is provided which is matched to the screw. Steel is chosen as the material for the extruded profile or flat iron shown, with preference being given to steel types which, in addition to high strength, also achieve a high surface quality of the nut thread. In principle, however, counter elements made of other suitable materials and with a cross-section different from the embodiment shown can also be used. In the assembly state shown, the counter element 103 rests with a broad side 105 on an inner surface 106 of the wall of the hollow profile. In the exemplary embodiment shown, webs 108, 109 are formed in the interior of the hollow profile in a hollow chamber 107 on the loading space side, through which contact surfaces for positioning the counter element 103 are provided in cross-section when the counter element 103 is initially loosely inserted. The carrier profile designed as a hollow profile also has a further hollow chamber 112 adjacent to a lower wall (see Fig. 16), which in the exemplary embodiment shown has an essentially square inner contour 113. In the partial section of Fig. 17, a reinforcing profile 114 is inserted to illustrate the possible variations, the outer contour of which is geometrically adapted to the inner contour 113 of the hollow chamber 112 in such a way that with only a small

VGN 265 098 23075N1 Mu./Bz./We/Or. 01.09.1 999

circumferential gap allows easy insertion of the reinforcing profile into the hollow chamber. It is further provided that the opening 100 of the wall 97 is designed as a slot opening which extends in the longitudinal direction of the hollow profile over its entire length.

Fig. 18 shows a partial section of the loading space structure 59 according to Fig. 12 along the section line XVIII-XVIII. In conjunction with Fig. 13, it can be seen that a holding element 116 is inserted into the front side of the support profile 60 and fastened thereto with a screw 117. A mandrel 119 is fitted into a cylindrical recess 118, by means of which a connection - indicated schematically - with a stanchion connection 120 of the loading space structure 59 is realized.

From Figures 19 and 20 in conjunction with Figure 12 it can be seen that a closure plate 121 is fastened to each of the front ends of the hollow profile 60 using thread-forming or self-tapping screws 122. As can be seen, for example, from Figure 18, the carrier profile 60 has clearances 123 in the edge areas into which a nut thread is cut by the screws 122 when the closure plate 121 is fastened. While Figure 19 describes a plan view of part of the loading space structure 59 according to Figure 12 in the direction of view 19 (with the insert element 88 cut), Figure 20 shows a partial section through the insert element 88 and parts adjacent to it, as indicated therein. It can be seen that the insert element 88 has an axial projection 124 relative to the carrier profile 60 at one end and a radial projection 125 with respect to its longitudinal axis. The radial projection 125 is formed by a strong

curved bend of the insert element 88. In further detail, the insert element 88 shown is a transversely flexible cord which is bent downwards in the longitudinal section running to the left of the carrier profile 60. While in Fig. 20 the insert element 88 or the cord is only shown up to the lower edge of the partial section, the insert element 88 or the cord can extend along the loading space structure up to a fastening element (not shown), for example up to a loop, an eyelet or another fastening element commonly used for this purpose. By fastening the insert element 88 to this, for example by knotting, a positional determination of the insert element 88 in the longitudinal direction is also achieved in the area of the carrier profile 60. The closure plate 121 has a recess 128, which is adapted in terms of its position and dimensions to the insert element 88 accommodated in the hollow profile 60. In addition, the closure plate 121 has an area 129 of reduced wall thickness adjacent to or integrated into the recess 128, which is adapted in terms of its position and dimensions to the bend of the insert element 88. The recess 128 and the area 129 thus form a depression in the surface of the closure plate 121 facing away from the carrier profile 60, in which the radial projection 125 is embedded, as it were.

This advantageously ensures that when the closure plate 121 is covered with a lateral tarpaulin as shown in Fig. 21, there is no risk of damage to the latter by the radial projection, since the radial projection is not point-like but extends over the recess 128 and the area 129.

VGN 265 098 23075N1 Mu./Bz./We/Or. 01.09.1 999

continuously protrudes from the closure plate 121. Accordingly, a further radial projection or a bend in the cord and a longitudinally adjoining fastening of the insert element 88 to the loading space structure 59 can be formed at the opposite end of the insert element 88.

All disclosed features are essential to the invention.
