The innovation concerns a box kit for trucks External sheet metal, consisting of case elements, an external frame and reinforcements made of metal profiles have, on the outside of which outer sheets are attached with the edges overlapping one another.

Box kits of the type mentioned consist of Wall elements, e.g. B. side, front and rear wall as well as roof elements, which by means of suitable design the outer frame profiles can be assembled to form the box body and attached to a truck.

For practical reasons, the outer sheeting of the wall elements cannot consist of one piece, but rather must consist of mostly rectangular, perpendicular or horizontally extending outer sheets are assembled.

So far it has been customary to overlap the outer sheets at the edges, with a stiffening profile for each overlap assign and rivet the outer sheets together and with the profile,

In the case of a standard box kit, around 4,000 rivets have to be set; In view of the fact that it must be drilled / thus manufactured by machining, this is a very complex procedure. Drilling weakens cross-sections and, for reasons of strength, forces the material to be correspondingly larger ^! cross-sections, which gives the well-known box kits additional weight.

Outer sheets cannot be riveted together without a stiffening profile will. On the one hand it would be difficult to maintain the flat state of the sheets, on the other hand can create a tight overlap of sheet metal of the usual wall thickness without a stiffening profile by riveting cannot be achieved. Consequently, the wall elements must have stiffening profiles at intervals that match the The grid corresponds to the sheet metal width, even if such profiles are not required in terms of strength technology would be. This also makes the wall elements heavier than necessary. Unnecessary weight of a box kit is known to reduce the available payload of the truck.

Each rivet represents a source of danger for the tightness because of the required drilling. Tightness opposite Air and especially moisture are essential. Therefore, extensive measures are required for testing and manufacturing the tightness required.

The result is the manufacturer's safe wall of well-known suitcase kits inappropriately large and the finished weights are too high.

The innovation is therefore based on the task of avoiding a box kit of the type mentioned at the beginning to train the aforementioned disadvantages as largely as possible without rivets.

To solve this problem, the aforementioned box kit is characterized according to the innovation in that the Outer sheets have single or double folds connecting the overlap edges and on or directly In addition to the single or double rebate, a non-cutting, flat connection with the parallel to the outer wall Have legs of the stiffening profile.

In the case of the newly designed box kit he

use single or double rebates to the greatest possible extent. An average of two thirds of the Nietver

bindings can be saved. Seams also form stiffening reinforcements for metal sheets / heightening hence the rigidity of the outer cladding and make some of the stiffening profiles superfluous. There folds No reinforcement profile is required to achieve a smooth sheet metal profile and a tight connection, other such profiles can be omitted.

While a riveted connection weakens, a seam connection stiffens the end. In addition to considerable labor savings, there is also a significant weight saving tion. By nature, folds are largely tight; Sealing problems are therefore avoided. According to the innovation trained box kits are therefore cheaper, easier and more functional to manufacture. About that Aesthetics also play a role; Rivet-free surfaces look better and more pleasing than rows of rivets interrupted surfaces.

An advantageous, non-cutting connection of the folded metal sheets with the stiffening profiles is shown in FIG Claim 2 an adhesive bond. There are metal adhesive connections that can only be separated again by cutting are. Thus, without damaging the outer skin of the outer sheet metal, a heavy-duty connection with the Outer sheets achieved.

Where special conditions prevail, can be connected according to claim 3 by means of adhesive tape.

High mechanical strength and tightness is achieved according to claim 4 in that the stiffening profiles are thickened hook-like on the back of the outer edge of the leg parallel to the outer wall and that the tensile

belonging single or double fold is positively pressed against this rear side.

In this development, the form fit creates a connection between the outer panel that can withstand high loads and reinforcement profile with simultaneous rabbet connection of the overlapping outer sheets. These Connection can be formed without gluing, but also additionally glued. With additional gluing, Above-average density achieved.

An embodiment of the suitcase kit designed according to the innovation is shown in the drawings. It shows:

The stiffening plates 8 have Rectangular shapes with the wall elements 2, 3, 4 the long side perpendicular to the roof wall element 5 run horizontally. The frame profiles 6 are hollow profiles with suitable corner, round, door hinge design, etc. You have a support surface for outer sheets 8 / riveted onto the latter in the traditional way and / or "to be glued"

The stiffening profiles 7 have a -T-shape and offer

therefore the outer sheets 8 have a surface parallel to the outer wall for attachment. They are placed where two outer sheets 8 butt and have distances that

these outer sheets 8 are folded together as shown in FIG. The formed fold 9 stiffens the connected outer sheets 8 such that a stiffening profile 7 can be dispensed with. Although a fold 9 is naturally high K ^ .ße is airtight and watertight, one cannot be shown

This procedure is particularly advantageous for the roof wall element 5, the fold 9 being arranged facing outwards or upwards. Of course it is that with the possibility of the fold 9 either inside or outside (based on the respective wall element 2, 3, 4, 5), does not change anything functionally or technically, but there is the possibility of to bring out the fold 9 as a design element if necessary.

In the embodiment according to FIG. 6, the fold 9 is not designed differently than according to FIG. 5, but it is located

basically - based on the wall element 2, 3, 4, 5 inside and it basically rests laterally on a stiffening profile 7, while the outer sheet 8 is directly rests flat on the surface of a leg parallel to the outer wall next to the fold 9. Reinforcement profile 7 and outer sheet 8 are flat verb ', -.den by means of a connection produced without cutting. This connection is preferably an adhesive bond, in which case adhesive tape (not shown) is also used, if necessary can be. The lateral contact of the fold 9 on the reinforcement profile 7 also results an advantageous power transmission between outer sheet 8 and reinforcement profile 7 in one for the adhesive connection Direction in the plane of the outer sheet 8.

In the embodiment shown in FIG. 7, the stiffening profile 7 has at the outer end of the outer sheet parallel Leg a thickening 10, which acts like a hook. The fold 9 is against the back of this leg and thus molded against the thickening 10. These The connection is form-fitting, i.e. it transmits forces in both directions in the plane of the outer panel 8. In addition, the outer sheet 8 can be connected to the outer surface by means of a friction layer 11 (possibly also adhesive tape) of the stiffening profile 7 be connected. The result of this design is maximum strength and a high degree of impermeability.
