Side wall

The invention relates to a side wall, in particular a side wall for trucks and truck trailers, which can be pivoted is hinged to the chassis of the vehicle.

Such side walls are butted against each other in the simplest possible way Boards made, which are connected to each other by appropriate steel bands.

On the one Längrar.d of such a side wall are then Hinge parts attached to the vehicle for swiveling attachment and eyelets and plug connections distributed over the side wall for fastening the tarpaulin by means of a line or chain and for the. bow frame.

Instead of simple boards, profiled boards are also used,
which essentially result in the same structure, although the
Profile boards can still be provided with tongue and groove and with
other superficial profiles.

It is also known to assemble side walls from extruded aluminum profiles of rectangular cross-section, the
The structure is similar to that for drop sides made from boards.

Even when using extruded aluminum profiles $ several profiles are arranged on top of each other and thereby blunt |

butted against each other and by tie rods, which either by the pro | files pass through or run outside the profiles, with one another i the connected. |

It is also known to make side walls for some purposes from pressed § Welding sheets together. | In all cases, however, an I produced in this way is

associate. >

This type of production is not only labor-intensive and expensive, but also requires many different building materials and components, different in terms of their shape, their intended use and often also in terms of their material.

The side walls all have numerous joints that not only prevent foreign matter and liquids from entering, for example Water, enable and can lead to corrosion, rotting and putrefaction, but also in the event of impact and impact can cause damage that is difficult, at least costly, to repair because of the damage, for example a wooden side wall, is often not just one profile board but several to be replaced, which in turn means that the parts, hinges, flanges and other parts have to be exchanged or renewed, but also undamaged parts for the purpose of exchanging the profiles must be loosened and reattached. Even when using aluminum profiles, these disadvantages are

H parts available. There are also joints there and the

The necessary anchors for the profiles are also included

f Damage affected or even destroyed, so that

; ■ repairs to such drop sides are time-consuming and therefore costly

are playful.

As already mentioned, a considerable disadvantage of the known drop sides is the fact that they are assembled from many different ones Parts and often different materials, so that impairments are not only due to the different material properties the condition of the ship's side arise by getting into the joints, cracks and grooves and other difficult-to-access spaces Substances can settle that affect the appearance and condition of the material.

Since these known drop sides never have a smooth, seamless surface but always have joints, protruding edges, no matter how fine and small, is also the preservation and thus maintaining the value of such a ship's side is difficult, and in some cases can only be maintained for a limited time.

The object of the present invention is therefore to create a drop side that does not have these disadvantages, which are simple in its design is, nevertheless, very stable and durable, which is inexpensive to manufacture and assemble, which has no joints and therefore considerably more resistant to the effects of corrosion and which is much cheaper than the conventional drop sides, even if damaged.

It is also lighter, it is jointless and therefore also easy to care for.

This task is achieved in that the side walls consists of a foam core and two cover layers attached to it, which are seamless and smooth and which protrude beyond the foam core Edges are connected to one another by deformation directly or with the interposition of a metal profile.

The cover layers preferably consist of a thin, surface-treated, in particular pre-painted sheet steel is connected to the foam core, d. H. is glued.

The connection of the sheets to the foam core can be done with a special adhesive, if that consists of the two cover layers with the intervening foam core existing structure is glued together from individual parts.

But it is also possible to foam the foam core between the two cover layers and thus the connection with the respective facing surfaces of the cover layers, d. H. to connect the sheets, with the facing sheet surfaces prepared accordingly could be.

This layer material is preferably produced continuously and in such a way that the sheet metal webs unrolled from the metal sheets, which form the inner and outer cover layers of the foam core form, are fed to a production line, the side edges being kept free from the foam core at a certain depth

The result is a three-layer structure that is attached to his
Has long sides sheet metal flanges, which the foam core around a
exceed a certain amount.

In pursuit of the concept of the invention is used to produce the A side wall made of two cover layers with an intermediate | i

should have finished side wall, whereupon between the protruding I

Sheet metal edges a profile is inserted, which essentially | H -shaped cross-section, with one side of the pro- '§,

exhibit. f.

The protruding '■

Sheet metal edges around the reinforced flange edges of the profile>, crimped or folded, so that in this way a firm mechanical connection between sheet metal and profile is established.

Preferably the outwardly facing surfaces of the | Flanges of the H -shaped profile, which consists of a light work- |

material, for example aluminum, with an adhesive layer |

so that when the profile is inserted between the sheet metal edges |

and / or when crimping the sheet metal edges around the adjacent Ϊ

The flange edges of the profile have a firm adhesive bond with the metal sheets ^{i

and the profile surfaces is brought about.

In a preferred embodiment, the profile is made on at least one side during the production of the laminate Sheet metal and foam core already incorporated and, if necessary, the sheet metal edges on one side already flanged around the reinforced, outward-facing flange edges of the profile.

In accordance with the concept of the invention, one sheet, preferably that which comes to lie to the outside of the finished ship's side or points to the outside, in a certain area be provided with a recess below the upper edge of the ship's side, which is used to attach fasteners and eyelets, to which the tarpaulin is then attached or the individual side walls are connected to the bow and stanchion system of the vehicle.

In the upper edge of the laminate between the protrusions A profile of this type can also be incorporated into sheet metal edges, but for most purposes it is sufficient to attach the sheet metal edges to connect this side by folding or by bending and gluing together.

As can be seen from the above description, the manufacture is carried out of the laminate preferably in a width that corresponds to the height of normal side walls. In this way now arises a completely uniform structure, both inside and outside,

very stable and thanks to the integrated foam core is resistant, but 'is easy, although thin sheets of steel of a thickness of about 0.5 are now only used for production be used.

Since the side walls are without joints, the side wall maintenance is easy, does not tend to corrosion and other destruction and Provides good insulation against heat transmission under certain uses.

Used to attach the required further parts that complete the side walls, for example hinge parts the H-shaped profile incorporated in the lower edge of the drop sides with its outward-facing reinforced edges and the smooth, plan inner gradations.

Because of this profile configuration, it is now possible to use, for example, molded bodies or molded pieces made of steel Inserted threaded holes formed therein, into which threaded bolts can be screwed, with which hinge parts ση the side wall can be attached. In the simplest case, you can simple hammer head screws can be used for this, whereby the cross-section of the hammer head of the screw is chosen so that it fills the interior of the profile with a good fit.

If desired, the drop side can also be be fixedly attached to the vehicle frame or to any part of the vehicle.

The invention will now be explained in more detail using an exemplary embodiment which is shown in the drawing.

Fig. 1: shows in perspective the material consisting of cover layers and foam core, which is used as The starting material for the manufacture of the ship's side is used, for the sake of better illustration the proportions are exaggerated,

Fig.la: shows the cross section through a profile part of the Side wall,

Fig. 2: shows a section of a side wall, the upper edge is still unprocessed and

Fig. 3: shows on an enlarged scale a possibility of manufacturing the upper edge of the Side wall.

As can be seen from Fig. 1, the material for producing the The side wall essentially consists of a laminate which, as shown in Fig. dsvgeoteil, made of two outer layers 1 and 2 made of sheet steel and one there is foam layer 3 lying between the cover layers.

As already explained above, this laminate can practically be produced from these three components using an assembly line process are, the sheets that form the cover layer 1 and 2 and the foam core 3 are already those for conventional drop sides have the required dimensions in width. A laminate according to FIG. 1 can be produced continuously in this way, which then only has to be cut to length, according to the side wall to be produced.

The cut edges are when the side wall is completed ^

for example, covered by a U-profile that can reach over but also between the sheets of laminate.

The ends to be covered by such a U-profile are the

1 transverse edges 4 and 5. There are practical grooves on the longitudinal edges 6 and 7

formed because the edges 8 and 9 or 10 and 11, the edges 12 and | 13 of the foam core 3 protrude.

The manufacture of such a part for making the inventive Drop side is essential because all other further manufacturing steps are based on it.

In the further description of the subject matter according to the invention, the longitudinal edge 6 is intended to be the lower edge of the ship's side, that is the edge, which is pivotably connected to the vehicle or the platform frame by a hinge.

For this purpose, in these, through the sheet metal edges 8 and 9 and the plastic edge 13 delimited an H -shaped slot Profile inserted, which is shown in cross section in Fig. La is.

This profile, which is denoted by the reference number 14, is preferably an extruded light metal profile, for example made of a suitable aluminum alloy and has dimensions in its width that correspond to the clear distance the sheet metal edges 8 and 9 correspond to each other. On the outside of the flanges at 15 and 16, the profile can be covered with a layer of adhesive or be covered with a self-adhesive film, the protective layer is removed when the profile 14 in the gap 17 at the bottom Edge of the laminate 1, 2, 3 is installed so that the insides the sheet metal edges 8, 9 or, if desired, 10, 11 fixed connect to the surfaces 15, 16 of the profile 14.

However, within the scope of the invention it is also possible to manufacture the laminate 1, 2, 3 in such a way that one of the Longitudinal edges, be it 6 or 7, already with an incorporated profile 14 is provided during manufacture. In any case, however, the inner surfaces of the sheets lie in the area of the Gap 17 snugly against the outer surfaces 15 and 16, while the foam core 3 the upper and the inwardly facing intermediate space 18 between the flanges 19 and 20 fills.

The depth of the gap 17 is dimensioned taking into account the width of the profile so that the sheet metal edges 8 and 9 or 10 and 11 still protrude by such a piece over the ends of the flanges 21, 22 that they protrude around the ends into the Level of the gradations 23 can be crimped. The space between the flanges 21 and 22 remains empty and is used for other purposes of arranging and actuating or fastening the ship's side.

In Fig. 2, an almost finished ship's side is shown in cross section. The reference number 1 again denotes the one cover layer made of sheet steel, which here faces outwards, the reference number 2 denotes the inward facing cover layer, 3 the foam core and the reference symbol 14 the profile according to FIG. La, which is embedded between the sheet metal edges 8 and 9, the outer edges of which at 24 and 25 are already around the ends of the flanges 21 and 22 are crimped.

As can be seen, the foam core 3 lies in the cavity 18 of the profile 14 and is firmly connected to the profile over the entire surface of this part.

The gradations 23 and 24 formed at the ends of the flanges 21 and 22 are used to fasten further parts, for example of hinge parts.

In the slot extending over the length of the side wall there are blocks, strips or nut bolts with a corresponding head

insertable, which correspond in their dimensions in terms of width and height to the dimensions of the slot shown in Fig. 1a the reference numeral 26 bears.

The inserted rods or blocks can be screwed into corresponding threaded holes in the rods or blocks are screwed in, are locked so that the part located on the rod or the block is then also in the Slot 26 of the profile 14 of the ship's side assumes a fixed permanent position.

It is also possible, for example, to use hammer head screws for fastening, with corresponding counterparts then place against the ends of the flanges 21, 22 over which the sheet metal edges 24 25 of the edge strips 8 and 9 or 10 and 11 are crimped.

The design can also be made so that the beading takes place up to the gradations 23 around, so that the Edges, which then do not have to run horizontally as shown in the drawing, but can also be slightly beveled - so dsß the inserts clamp the edges of the flanges of the facing sheets at the same time as the corresponding parts are screwed tight and secure.

The interior space between the metal sheets or cover layers is now, as is readily apparent from the description above, full.

constantly filled with a foam, for example a May be polyurethane foam or any other suitable foam and that of the rigidity and strength of the ship's side contributes constructively, but is also sufficiently elastic, so that, for example, a striking against the outer sheet 1 Perhaps the blow will dent or tear the outer sheet 1, but this energy is consumed in the foam core by elastic Deformation of the same, so that the inner sheet 2 no

has a corresponding bulge, which is the case with conventional drop sides | mostly the foil is so that the inner surface of the ship's side remains flat and thus damage to the load, e.g. B. is avoided.

In the upper region of the outer cover layer 1, as shown in FIG. 2, there is a bead approximately trapezoidal in cross section which bears the reference number 27. The course of this bead is in the longitudinal direction of the drop side and is used to attach

ff eyelets 28 or hinges or other means for operating the drop side

or facilities serving the vehicle. |

The upper edge 7 in Fig. 2 does not contain such profiles, although it could also contain such a profile, the whole and even how the lower profile 14 is fitted and also connected to the sheet metal edges 10 and 11.

The slot 26, which is then open and has no further function has to take over, could for example be sealed by an insertable plastic profile, mushroom-shaped cross-section.

Such a mushroom-shaped profile 29 is shown in dashed lines in FIG shown in connection with the lower profile 14, but this corresponds quite analogously to the upper profile.

However, it will be easiest and most expedient if the upper sheet metal edges 10 and 11 according to FIG. 2, as shown in FIG. 3, are brought together and folded, as indicated at 30. The fold also contributes to the stiffening and results in an advantageous, surprisingly simple and stable closure for the upper end of the ship's side. If desired, the fold 30 can of course also be on the inner edge or in the corner area, for example at 31.

In summary, a shipboard is proposed according to the invention, which has a simple, light and solid design, practically a uniform structure, no dead spaces or joints or cracks that can lead to corrosion, rotting or weathering, a completely smooth outer and inner surface and is therefore easy to care for.

Local damage does not always have an effect the entire diameter or the entire length of the ship's side, as shown above, but are locally limited.
