Description

The present invention relates to a floor structure for a vehicle, trailer or the like.

From the US 5,054,843 A is a floor construction of the aforementioned type, in which the upper cover layer comprises an extruded profile, which is flat on its underside and has at its top in the vehicle longitudinal direction extending T-slots. The EP 0 348 629 A2 teaches a heat-insulating floor construction whose upper cover layer comprises a corrugated extruded profile which has T-shaped supports on its upper side and T-shaped webs on its underside, which serve for anchoring in a foam material. Other floor constructions are from the US 2004/0045847 A1 . US 2006/0070548 A1 and WO 01/83327 A1 , known.

The invention is based on the object to provide a floor construction, which allows easy positioning of cargo securing elements and prevents the penetration of moisture from below onto the loading area.

To solve this problem, a floor construction with the features of claim 1 is provided.

According to the invention, at least one fastening groove is formed on the upper side of the extruded profile of the upper cover layer, which extends in the longitudinal direction of the extruded profile and has a double-V-shaped cross-section which is defined by a W-shaped wall section and only two serifike overhangs which define the fastening groove at least partially projecting from opposite sides. The mounting groove allows in a particularly simple manner a mounting and positioning of load securing elements, such as load securing struts, load securing wedges, locking bars, anti-slip mats and the like. Furthermore, partitions for dividing a cargo space in the mounting groove can be mounted. In addition, the mounting groove forms a ventilation channel, which contributes to the fact that even at full load of limited by the floor structure cargo space can still circulate air therein.

Advantageous embodiments of the invention are described in the dependent claims, the description and the drawings.

According to one embodiment, the hollow regions of the extruded profile are defined by webs which extend from an outer wall of the extruded profile vertically inwards towards the supports and have transverse limbs at their inner ends, which give the webs the shape of an L or an inverted T. Preferably, the webs abut with their transverse legs on the carriers.

According to the invention, the extruded profile is composed of a plurality of adjacently arranged profile segments. As a result, the production of the floor construction is further simplified because the extruded profile does not have to be kept for different applications in the respective width of the floor construction, but instead, the extruded profile can be assembled as needed from a required number of identical or similar profile segments.

According to the invention adjacent profile segments are connected to each other via a labyrinth-like joint. The labyrinthine design of the joints helps to prevent moisture from entering the interior of the floor structure.

The joints may each comprise a formed on a web of a profile segment groove-like depression and a form-fitting engaging in the recess spring-like web of the other profile segment.

To further improve the tightness of the joints and the stability of the extruded profile even further, the profile segments are preferably additionally welded together tightly.

According to a further embodiment, the extruded profile is firmly connected to the carriers, in particular in the region of the joints. In principle, it would be sufficient to screw the extruded profile with the carriers only or just to glue. An increased stability of the floor construction is achieved, however, when the extruded profile is both bolted and glued to the carriers.

According to a further embodiment, at least one guide recess is formed in the extruded profile of the upper cover layer, which extends in particular in the longitudinal direction of the extruded profile. Such guide troughs serve, similar to so-called Jolodaschienen, for guiding the roles of a carrier roller or lift truck in a loading or unloading process and thus facilitate the handling of cargo. The depth of the guide troughs can basically be chosen arbitrarily, as long as they ensure a guiding property. Wall sections of the extruded profile, which define the bottoms of the guide troughs should, if possible, not be lower than the transverse sections of the webs of the extruded profile in order to ensure uniform contact of the extruded profile with the straps over the entire width of the extruded profile.

According to yet another embodiment, a groove structure is formed on the upper side of the extruded profile of the upper cover layer, which extends in particular in the longitudinal direction of the extruded profile. The groove structure increases the friction of charge stored on the floor constructions and thus helps prevent unwanted slippage of the load. In addition, the groove structure increases the safety when walking on the floor construction. In order to increase the friction even further, mutually spaced transverse notches may be embossed on the upper side of ribs of the groove structure.

By extending the groove structure in the longitudinal direction of the extruded profile, on the one hand, the surface of the floor structures can be cleaned more easily and, on the other hand, the loading noise, which is caused, for example, by a forklift moving on the floor constructions, is considerably reduced.

Moreover, the longitudinal orientation of the groove structure, similar to the mounting grooves, allows for a continuous air flow of air conditioning air, even with charge sealed in foils.

Advantageously, the height of the groove structure is adapted to the thickness of a horizontal leg of a lateral termination angle and a lateral edge region of the extruded profile free of groove structure, so that the upper side of the horizontal leg of the attached in the edge region on the extruded profile terminates flush with the top of the groove structure. Such a termination angle can be, for example, a lateral ramming protection.

According to a further embodiment, the extruded profile has at least one hollow chamber which is closed relative to the intermediate space and which is bounded in particular by two adjacent webs. The hollow chamber allows, for example, a heating of the floor construction. Further, it is possible to introduce communicating with the hollow chamber openings in the top of the extruded profile of the upper cover layer, through which hot air supplied via the hollow chamber can be introduced into a cargo space. As a result, a cargo space, for example, for flower transports in an advantageous manner air-conditioned.

In order to prevent undesired penetration of moisture into the floor construction, a load-side opening-side front end of the extruded profile is preferably closed by a closing profile. The end profile advantageously forms a receptacle for a heat insulating body, which in particular has an elastically deformable material, such as rubber.

In order to allow a supply of hot air into the at least one hollow chamber, adjacent to the extruded profile rear wall of the end profile may be provided with an opening which is aligned with the hollow chamber of the extruded profile. Conversely, the opening in the rear wall of the end profile also allows moisture to escape from the hollow chamber, which may have penetrated into the hollow chamber through openings in the extruded profile, for example after cleaning the top of the bottom construction.

The invention relates to a floor structure for a vehicle, trailer or the like with a support frame, in particular a ladder frame on which a bottom plate forming extruded profile is mounted, which has downwardly open hollow areas. The extruded profile may have webs with transverse sections, a groove structure, fastening grooves, hollow chambers and / or guide recesses.

According to one embodiment, the support frame transverse to the longitudinal extent of the extruded profile extending cross member on which the extruded profile is seated with the transverse sections of its webs. Alternatively, however, a support frame with extending in the longitudinal direction of the extruded longitudinal members conceivable that are not in contact with the webs, but bear in an area located between two adjacent lands on the upper wall of the extruded profile. If the longitudinal beams are T or double T beams, it is advantageous to make the distance between the adjacent beams correspondingly wide.

The height of the extruded profile can be chosen so that its upper side is substantially flush with the upper side of an outer frame of the support frame. Alternatively, however, the extruded profile can also be made higher be. This makes it possible with a corresponding design of an edge profile segment of the extruded profile, for example, in forming a lateral overhang on the outside of the edge profile segment, lashing, such as lashing hooks, laterally slidably mounted laterally on the extruded profile. In the lashing can be hung with suitable hook straps or the like.

In Fig. 1 to 13 a non-inventive floor construction is shown, which is characterized by a so-called sandwich construction.

Seen from bottom to top, the bottom construction comprises a sheet-metal covering layer 10, which is glued to a plywood pressure plate 12 lying thereon ( Fig. 1 ). Alternatively, the cover layer 10 can also be formed from another suitable material, such as, for example, GFRP or CFRP.

At suitable distances from each other cross beams 14 made of laminated wood on the plywood pressure plate 12 are arranged, which are glued to the plywood pressure plate 12 and / or connected by suitable connecting elements with this ( Fig. 2 ).

The cross beams 14 extend in a direction transverse to the longitudinal direction of the floor construction, wherein the longitudinal direction of the floor construction coincides with the longitudinal extent of a vehicle or container.

On the cross beams 14, a longitudinally extending extruded profile 16 is arranged, for example, an extruded profile or a Strangziehprofil aluminum, which is glued to the cross members 14 and additionally connected by suitable connecting elements 15, for example, is screwed ( Fig. 4 ).

A limited by the plywood pressure plate 12, the cross member 14 and the extruded profile 16 space 18 is at least approximately completely filled by a foam material 20 ( Fig. 1 ).

The extruded profile 16 is seen in the transverse direction of several profile segments 22 together ( 3 and 4 ). At least two different variants of profile segments 22 occur, which, however, differ only slightly from each other, as will be explained in more detail below.

In principle, each profile segment 22 has a horizontally extending upper wall 24, from which a plurality of webs 26 extend vertically downwards. The number of webs of a profile segment 22 may vary depending on the variant of the profile segment 22. In the illustrated embodiment, a middle profile segment 22a, for example, nine webs 26, whereas lateral profile segments 22b each have only six webs 26.

At their lower ends, the webs 26 each transition into a horizontally extending transverse section 28, which is either centrally aligned with the web 26 and this gives the shape of an inverted T or which is to form an L-shape only to one side of the Footbridge 26 extends away.

Adjacent profile segments 22 are connected to one another via a labyrinth-like joint 30. To form the joint 30, the one profile segment 22 on an L-shaped web 26 a, which is provided with a vertically extending groove 32. Accordingly, the outermost web 26b of the adjacent profile segment 22 is formed so that it can engage positively in the groove 32 of the other profile segment 22. The engaging in the groove 32 spring-like web 26 b is provided with a transverse projection 34 which rests on a groove 32 defining the vertical portion 36 of the other web 26 a.

To increase the strength of the extruded profile 16, the profile segments 22 are additionally welded together.

The screwing of the extruded profile 16 with the cross members 14 takes place at the transverse sections 28 of the L-shaped webs 26 a, which form the joint 30 of adjacent profile segments 22.

As in Fig. 2 can be seen, the lateral profile segments 22b respectively at the bottom of its outer web 26c a vertically downwardly extending side wall 38 which engages over an upper region of the lateral end faces 40 of the cross member 14. On the side walls 38, an additional lateral screw 39 of the extruded profile 16 is provided with the cross members 14.

Incidentally, the beam frame formed from the cross beams 14 is laterally closed by profiled strips 43 which adjoin the side walls 38 of the extruded profile 16 from below.

The webs 26 of the profile segments 22 bound to the gap 18 open hollow areas 42 of the extruded profile 16, which are filled as the gap 18 with the foam material 20. In this case, the hollow regions 42 of the extruded profile 16 delimiting surface regions of the extruded profile 16 are not smooth, but provided with a certain surface structure, for example, they may be formed along grooved. This surface structure ensures that the foam material 20 has a more intensive connection with the extruded profile 16 enters, in particular better adheres to the upper wall 24 of the extruded profile 16 and can not easily detach from this. The adhesion of the foam material 20 to the inside of the extruded profile 16 can be further improved if the inside of the extruded profile 16 is provided with a suitable adhesion promoter.

As Fig. 4 shows, each profile segment 22 has a longitudinally extending hollow chamber 44 which is bounded laterally by adjacent webs 26 and from above by the upper wall 24. On its underside, each hollow chamber 44 is bounded by a horizontal partition wall 46 connecting the adjacent webs 26, which separates the hollow chamber 44 from the hollow region 42 and prevents foam material 20 from entering the hollow chamber 44.

At the top of each profile segment 22 a double V-shaped mounting groove 48 is formed, which is defined by a W-shaped course of the upper wall 24 of the extruded profile 16. At the top of the upper wall 24, two projections 50 are formed, which at least partially project beyond the fastening groove 48 from opposite sides and thereby form undercuts which allow anchoring of an anchoring means engaging in the fastening groove 48.

From a central elevation 54 of the W-shaped portion of the top wall 24, a web 26 extends vertically downwardly adjacent to at least one land 26 defining a hollow chamber 44. In a middle profile segment 22a, a hollow chamber 44 is arranged on both sides of the fastening groove 48, whereas in the case of the lateral profile segments 22b, only the inner, ie the side wall 38 facing away from the mounting groove 48, a hollow chamber 44 is provided.

The hollow chambers 44 fulfill several functions. First, they allow the passage of hot air to control the temperature of the floor construction or the supply of hot air in a limited space through the floor space when openings are provided in the upper wall 24 of the extruded profile, which allow the escape of the hot air from the hollow chambers 44 into the loading space ,

On the other hand, however, larger openings 56 can also be formed over the hollow chambers 44 in the upper wall 24 of the extruded profile, which allow a fixing of load securing means, such as, for example, securing wedges 58, eg paper roll wedges or blocking rods 60 ( FIGS. 5 and 6 ). Alternatively or additionally, these openings 56 can serve for fixing a partition wall guided on the ceiling of the loading space.

As already mentioned, the fastening grooves 48 serve to receive anchoring means, which may be formed, for example, in the form of anchoring slides 52 which have on their underside two hooks 62 engaging in the fastening groove 48, which engage behind the projections 50 of the fastening groove 48 (FIG. Fig. 7 ).

In order to prevent inadvertent displacement of the anchoring slides 52 in the longitudinal direction, they may be provided with a latching mechanism, which allows a fixing of the anchoring slide 52 in a desired longitudinal position within the fastening groove 48. Alternatively or additionally, the fixation of the anchoring carriage 52 by means of a clamping mechanism, ie done by frictional engagement.

Depending on the application, the anchoring carriages 52 may be provided with a bracket 64, which makes it possible to hook in a load-securing belt 66 ( Fig. 7 ), or they can, as in Fig. 8 shown to be provided for connection to a strut 68 for supporting cargo.

As can be seen in the figures, the top of the extruded profile 16 is provided with a groove structure 70 formed by a plurality of equally high ribs 72 which are transversely spaced from one another and extend longitudinally from the top wall 24 , As Fig. 9 shows, the height of the ribs 72 is adapted to the height of the projections 50.

Only in the outer edge regions 74 of the lateral profile segments 22b does the extruded profile 16 have no groove structure 70. This makes it possible to mount lateral ramming protection angles 76 in the edge regions 74 in such a way that the upper side of a lower, horizontally extending angled section 78 runs flush with the upper side of the ribs 72.

The groove structure 70 contributes to the slip resistance and thus to securing the load or to a safe ascent. For additional fixation of a load mounted on the floor construction, a stop bar or an abutment angle 80 can also be placed on the floor construction, which is complementary to the groove structure 70 on its underside, ie, has recesses 82 in which the ribs 72 engage can ( Fig. 10 ).

In order to more effectively prevent slippage of cargo on the floor structure, it is also possible to apply one or more anti-slip mats 84 to the extruded profile 16, which are formed for example from a rubber material and may have a friction-increasing surface structure 86 on its upper side ( Fig. 11 ).

Here, a first variant of anti-slip mat 84a is conceivable, which is placed only on the groove structure 70 and similar to the stop angle 80 has on its underside a to the groove structure 70 complementary surface ( Fig. 11b ). In contrast, a second variant of anti-slip mat 84b on its underside two hook-shaped extensions 88 which can be clipped into the mounting groove 48 in order to fix the anti-slip mat 84b on the extruded profile 16 ( Fig. 11c ). Similar to the stop angle 80, the anti-slip mats 84 can either be placed only on the extruded profile 16 or clipped in the case of the second variant with this or additionally glued to the extruded profile 16.

As Fig. 12 shows, in the area of a loader opening side front end of the bottom construction, a transversely extending end profile 90 is welded to the extruded profile 16, which covers the hollow portions 42 and the hollow chambers 44 and rests on a terminal cross member 14a. The end profile 90 has a substantially L-shaped profile with a resting on the end cross member 14 a first horizontal leg portion 92, which merges at its profile facing 16 end into a vertical leg portion 94, which effectively forms a rear wall of the end profile 90, and with a to the first horizontal leg portion 92 substantially parallel second horizontal leg portion 96 extending from the vertical leg portion 94 of the Extruded profile 16 extends away. The upper side of the second horizontal leg section 96 extends substantially flush with the upper side of the groove structure 70 of the extruded profile 16.

The end profile 90 forms a receptacle for a strip-shaped heat insulation body 98, which is formed in the present embodiment of a rubber material and is also referred to as "drive-over rubber". The heat insulating body 98 has a substantially rectangular cross section with an edge section 16 facing the edge portion, which is positively received between the horizontal leg portions 92, 96 of the end profile 90, a raised central portion whose top has an exposed surface area 124 which is substantially flush with the Top of the second horizontal leg portion 96 extends, and a side facing away from the extruded profile 16 edge portion with a lowered surface area 100th

In order to fix the heat insulation body 98 in the end profile 90, 90 mutually opposite pairs of locking projections 102 are formed on the inner sides of the horizontal leg portions 92, 96 of the final profile, which engage in correspondingly provided pairs of locking grooves 104 of the heat insulating body 98.

As Fig. 13 shows, a U-shaped sill profile 106 is placed on the loading space opening side front end of the floor construction. The sill profile 106 comprises a first horizontal section 108 which overlaps the underside of the floor construction, a vertical section 110 covering the front side and a second horizontal section 112 which overlaps the lowered surface area 100 of the heat insulation body 98.

In this case, the thickness of the second horizontal section 112 is adapted to the lowering of the lowered surface area 100 in such a way that the upper side of the second horizontal section 112 of the sill profile 106 is substantially flush with the upper side of the middle section of the thermal insulation body 98. The second horizontal portion 112 is thus separated from the second horizontal leg portion 96 of the end profile 90 by the central portion of the heat insulating body 98. The sill profile 106 thus has no direct contact with the end profile 90, i. There is no thermal bridge between the sill profile 106 and the extruded profile 16.

Between the vertical section 110 of the sill profile 106 and the end cross member 14a of the floor construction, a metal support 114 is arranged, which serves for holding an espagnolette closure 116 of a door 118 closing the loading space.

As Fig. 13 show, projecting a plurality of sealing lips 120 on the bottom 122 of the door 118, of which with the door closed at least one of the second horizontal leg portion 96 of the end profile 90, with the exposed surface portion 124 of the central portion of the heat insulating body 98 and the second horizontal portion 112th the sill profile 106 is engaged. In this case, the sealing lips 120 are preferably positioned such that at least over the exposed surface area 124 of the heat insulation body 98 a temperature-neutral cell bounded by two adjacent sealing lips 120 is formed, which prevents direct heat transmission. In this way, the cargo space with the door closed 118 is optimally insulated from the environment thermally.

The vertical leg portion 94 of the end profile 90 is provided with openings not shown in the figures, which are aligned with the hollow chambers 44 of the extruded profile 16 and thus allow a frontal access to them. Correspondingly, channels (not shown) are formed in the heat insulation body 98, which open to the openings in the end profile 90 and thus to the hollow chambers 44 of the extruded profile 16.

The channel system formed in the heat insulation body 98 is accessible from the outside via an access opening 126 which is provided on a front side of the heat insulation body 98 facing away from the extruded profile 16, as in FIG Fig. 11 is shown. To the access opening 126, a not shown pipe system can connect, which is passed down through the lower horizontal portion 108 of the sill profile 106.

An opening 128 provided on a side surface of the heat insulating body 98 is a result of the manufacturing process and is closed with a plug.

Via the access opening 126 and the channel system formed in the heat insulation body 98, it is possible to introduce warm air into the hollow chamber 44 in order to heat the floor construction in the manner of a floor heating system. As already mentioned, it is also possible to introduce the warm air directly into the cargo space, if corresponding openings in the upper wall 24 of the extruded profile 16 are provided, through which the hot air from the hollow chambers 44 can escape into the cargo space.

Conversely, the channel system in the thermal insulation body 98 can also be used to drain moisture from the hollow chamber 44, For example, if after a wet cleaning of the cargo compartment floor moisture has penetrated through the Warmluftausströmöffnungen or through other fixing or mounting holes in the hollow chamber 44. It goes without saying that the access opening 126 can be closed by a suitable closure means as needed. The access to the access opening 126 can also be controlled by means of a valve.

To produce the floor construction, the plywood pressure plate 12 is first glued to the sheet metal top layer 10. Subsequently, the cross member 14 are connected to the plywood pressure plate 12, for example glued. Then the profile segments 22 are placed either on the side or from the middle starting on the cross member 14 and glued to the cross members 14 and screwed. In addition, the individual profile segments 22 are welded together. The beam frame formed from the cross members 14 is also closed laterally by the profile strips 43. Thereafter, the foam material 20 is at several points in the plywood pressure plate 12, the cross member 14, the extruded profile 16 and the moldings 43 limited spaces 18 injected so that the foam material 20, the intermediate spaces 18 and the hollow portions 42 of the extruded profile 16 at least approximately completely fills ,

In the extruded profile 16 according to the embodiment described above, the lateral profile segments 22b are in principle like the other profile segments 22a formed with the difference that they each have a downwardly extending side wall 38 which engages around the cross member 14 side.

Alternatively, the lateral profile segments 22b, as in the erfindungsgmäßen Fig. 14 shown, formed in two pieces and on the one hand a side end profile 130, which has an inwardly open C-shaped profile section 132, from which the side wall 38 extends downward, and on the other hand, a resting on the cross members 14 segment section 134 include. The segment portion 134 is in principle like the other profile segments 22a formed with the difference that it has a free horizontal wall portion 136 which projects beyond the C-shaped profile portion 132 of the side end profile 130 and is firmly connected thereto, for example by means of gluing, welding , Riveting or screwing.

The two-part design of the lateral profile segments 22b allows the compensation of tolerances in the width of the individual profile segments 22, which could lead to a total width of the extruded profile 16, in which the vertical side walls 38 of the lateral profile segments 22b would no longer rest against the carriers 14. For this purpose, the lateral end profiles 130 are first attached to the cross members 14 during assembly of the floor construction, and then the segment sections 134 resting on the transverse beams 14 are connected to the respectively adjacent central profile segments 22a and the lateral end profiles 130.

In the floor constructions according to the preceding embodiments, in each case only one extruded profile 16 is provided, namely that which forms the upper cover layer of the floor construction. The non-inventive Fig. 15 shows an alternative floor construction, in which both the upper cover layer and the lower cover layer is formed by an extruded profile 16. The upper extruded profile 16a is of the type described above.

The lower extruded profile 16b may in principle be identical to the upper extruded profile 16a. Since on the bottom of the bottom construction normally no hollow chambers, mounting grooves or mounting holes, etc. are needed, a simpler version of extruded profile 16b is preferred for the bottom of the floor construction, which, as in Fig. 15 is shown, a substantially smooth bottom wall 24b, from which webs 26 extend upward in the direction of the cross member 14, at the ends of transverse sections 28 are provided. The lower extruded profile 16b is composed of profile segments 22, which are connected to each other by means of joints 30 of the type already described.

The downwardly extending side wall 38a of the side profile segment 22b of the upper extruded profile 16a and the upwardly extending side wall 38b of the lateral profile segment 22b of the lower extruded profile 16b have guide grooves 137 on facing end faces into each of which a trim strip 138 is inserted, e.g. clipped, can be to complete the interior of the floor construction for the foaming process and / or to create an adhesive surface for mounting a side wall. The end strip 138 is preferably formed of a poorly heat-conducting material to provide thermal separation between the upper and lower extrusions 16a, 16b and to further enhance the overall thermal insulation properties of the floor construction.

Some of the profile segments 22 of the lower extruded profile 16b may have an increased distance between two adjacent webs 26 (FIG. Fig. 15a ), which allows the use of a solid aluminum insert 139, in which a thread can be cut, so that the bottom construction can be pressed against a side rail 140. An otherwise The aluminum insert to be provided in the cross member 14 of the floor construction can thus be dispensed with, ie all the cross members 14 can be formed uniformly.

At the in Fig. 15 illustrated embodiment, the lower extruded profile 16b is located with the transverse sections 28 of its webs 26 on the underside of the cross member 14, similar to the upper extruded profile 16a with the transverse sections 28 of its webs 26 is seated on the top of the cross member 14.

Alternatively, on the underside of the cross member 14 but also guides 142, for example in the form of slot-shaped receptacles, be formed for the webs 26 of the lower extruded profile 16b, which allow the cross member 14 to be pushed onto the webs 26 for connection to the lower extruded profile 16b ( Fig. 16 ). In order to produce the most secure and play-free connection between the cross member 14 and extruded profile 16b, the profile of the guides 142 is adapted to the profile of the webs 26, ie some guides 142 have a T-shaped profile and other guides 142 has a profile in the form of an inverted L. on. In order to minimize the sliding paths for the cross member 14, the webs 26 of the lower extruded profile 16b may be partially disengaged for dipping the cross member 14.

In Fig. 17 to 22nd is a bottom structure shown, which has at least no significant heat-insulating properties, but this is characterized by a particularly simple structure and can be used for example in truck trailers or trailers.

The floor construction includes a ladder frame 144 having an outer frame 146 and a plurality of crossbars, not shown. Of the Outer frame 146 is composed of two transverse profiles 148, which are interconnected by two longitudinal profiles 150.

On the lead frame 144, a bottom profile forming extruded profile 16 is mounted, which has downwardly open hollow portions 42. The extruded profile 16 is formed similarly to the extruded profile 16 of the upper cover layer of the above-described heat-insulating floor construction, i. it is composed of a plurality of profile segments 22 which are interconnected by means of above-described joints 30. Some of the profile segments 22 may be identical to the profile segments 22 already described above, in particular with the middle profile segments 22a.

In addition, the extruded profile 16 of in Fig. 17 to 22nd shown embodiment profile segments 22c, in which guide troughs 152 are formed for guiding the rollers of a carrying roller or lift truck ( Fig. 20 ). The depth of the guide troughs 152 can basically be chosen arbitrarily, as long as it ensures a guiding property. Wall sections of the extruded profile 16, which define the bottoms 154 of the guide troughs 152, should, if possible, not be lower than the transverse sections 28 of the webs 26 of the extruded profile 16 to ensure a uniform abutment of the extruded profile 16 on the cross members 14 over the entire width of the extruded profile 16 ,

On both sides of each guide trough 152 hollow chambers 44 are formed in the extruded profile 16, the bottom of which holes, which may be provided in the upper wall 24 of the extruded profile, protects against splash water from below. Such bores may, as already mentioned, for fastening a load securing element, eg a wedge 58 (FIG. Fig. 22 ), be used.

As Fig. 18 and 19 show, the height of the extruded profile 16 may be selected so that the top of the extruded profile 16 is substantially flush with the tops of the transverse profiles 148 and longitudinal profiles 150 of the outer frame 146 of the lead frame 144.

In FIGS. 20 to 22 an alternative extruded profile 16 is shown, which not only has a greater height compared to the extruded profiles 16 described above, but also has a specially designed lateral profile segment 22b. Concretely, this lateral profile segment 22b has a laterally outwardly extending portion 156 which at least partially projects beyond an upper region of the associated longitudinal profile 150 of the outer frame 146.

At the outer end of the laterally outwardly extending portion 156, a C-shaped profile section 158 is formed, which has an upper leg 160 and a lower leg 162 which engages in a recess 164 provided in the longitudinal profile 150.

The C-shaped profile section 158 allows cargo securing elements, such as e.g. Lashing hooks 166, to hang on the extruded profile 16 laterally and longitudinally continuously displaceable. Lashing straps or the like may be attached to the lashing hooks 166 as appropriate and in a suitable manner.

When related to Fig. 17 to 22nd described embodiments, it was assumed that the extruded profile 16 is mounted on transversely extending cross member 14, for example, glued, screwed, riveted (also in the Stanznietverfahren) or clinched. Fig. 23 shows an embodiment in which the extruded profile 16 on T-shaped side members 168 is mounted, which extend in the longitudinal direction of the extruded profile 16. The extruded profile 16 has for this purpose areas in which two adjacent webs 26 are spaced apart from each other so far that they can receive a transverse section 170 of the longitudinal member 168 between them and the upper wall 24 of the extruded profile 16 can rest on this.
