Description

Die Erfindung betrifft eine Verbindung zwischen wenigstens zwei Bauteilen eines Lastkraftwagens, Anhängers und/oder Aufliegers, mit einem Verbindungselement, wobei das eine Bauteil ein metallischer Grundkörper mit einer Öffnung ist, wobei das andere Bauteil ein Anbauteil mit ebenfalls einer Öffnung ist, wobei ein Verbindungsstift des Verbindungselements durch die Öffnung des Anbauteils hindurchgreift, wobei auf der dem Grundkörper abgewandten Seite der Öffnung des Anbauteils das Verbindungselement einen Verbindungskopf aufweist, wobei der Verbindungskopf durch seine Größe ein Abziehen des Anbauteils vom Verbindungsstift verhindert, wobei das Verbindungselement einteilig ausgebildet ist und wobei der Verbindungsstift wenigstens abschnittsweise in die Öffnung des Grundkörpers eingesteckt sowie unmittelbar in der Öffnung des Grundkörpers gehalten ist.The invention relates to a connection between at least two components of a truck, trailer and / or semi-trailer, with a connecting element, wherein the one component is a metallic base body with an opening, wherein the other component is an attachment with also an opening, wherein a connecting pin of Connecting element passes through the opening of the attachment, wherein on the side facing away from the base body of the opening of the attachment, the connecting element has a connecting head, the connecting head by its size prevents removal of the attachment from the connecting pin, wherein the connecting element is integrally formed and wherein the connecting pin at least partially inserted into the opening of the body and is held directly in the opening of the body.

Verbindungen der genannten Art sind in verschiedenen Ausgestaltungen seit langem bekannt. Dabei handelt es sich insbesondere um Schraubverbindungen, Nietverbindungen oder Verbindungen mit einem Bolzen, der mittels eines Splints gesichert ist. Diese Verbindungsarten kommen auch beim Zusammenbau von Lastkraftwagen, Anhängern von Lastkraftwagen oder sogenannten Aufliegern, insbesondere von deren Aufbauten, zur Anwendung (siehe z.B. DE 32 45 205 A ).Compounds of the type mentioned have long been known in various embodiments. These are in particular screw connections, riveted joints or connections with a bolt, which is secured by means of a split. These types of connections are also used in the assembly of trucks, trailers of trucks or so-called semi-trailers, in particular of their structures, used (see, eg DE 32 45 205 A ).

Die genannten Verbindungen lassen sich heute problemlos herstellen, allerdings erfordert dies die Handhabung speziellen Werkzeugs und/oder eine Reihe von Arbeitsschritten, was die Montagezeiten und die Montagekosten in die Höhe treibt. Dies ist bei der Herstellung der zuvor genannten Güter besonders bedeutsam, da dabei eine ganze Reihe der genannten Verbindungen benötigt wird. Zudem verursacht die Montage solcher Einrichtungen einen erheblichen Teil der Gesamtkosten. Aus diesem Grunde besteht ein Bedarf an möglichst einfach und schnell herzustellenden Verbindungen, um die Montagekosten zu senken.The compounds mentioned can be easily produced today, but this requires the handling of special tools and / or a series of steps, which increases the assembly times and installation costs drives. This is particularly important in the production of the aforementioned goods, since a whole series of said compounds is required. In addition, the installation of such facilities causes a significant portion of the total cost. For this reason, there is a need for as simple and fast to produce connections to reduce installation costs.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die Verbindung der genannten Art derart auszugestalten und weiterzubilden, dass die Möglichkeit einer Manipulation von Nutzfahrzeugaufbauten vermindert wird.The present invention is therefore based on the object, the compound of the type mentioned in such a way and further, that the possibility of manipulation of commercial vehicle bodies is reduced.

Die zuvor genannte Aufgabe ist erfindungsgemäß durch eine Verbindung nach Anspruchs 1 gelöst.The aforementioned object is achieved by a compound according to claim 1.

Die Erfindung hat erkannt, dass die Montage durch die Verwendung einer Steckverbindungen beschleunigt und vereinfacht werden kann, da keine besonderen Werkzeuge für die Montage von Nöten sind. Das Verbindungselement muss weder in ein zuvor geschnittenes Gewinde eingeschraubt werden, wie dies bei Schraubverbindungen der Fall ist, noch muss die Verbindung von der Rückseite des Grundkörpers mit einem Splint gesichert werden. Auch kann auf das umständliche Einführen einer Niete und das anschließende Befestigen der Niete verzichtet werden. Das Verbindungselement wird einfach eingesteckt, ohne dass weitere Arbeitsschritte vorgesehen werden müssen. Es wird also auch nicht etwa eine Verbindung nach Art eines Dübels geschaffen, bei dem nach dem eigentlichen Einführen des Verbindungselements noch ein Spreizen des Verbindungselements gewährleistet werden muss.The invention has recognized that the assembly can be accelerated and simplified by the use of a connector, since no special tools for mounting are needed. The connecting element does not have to be screwed into a previously cut thread, as is the case with screw connections, nor must the connection be secured from the back of the base body with a split pin. Also can be dispensed with the cumbersome insertion of a rivet and the subsequent attachment of the rivet. The connecting element is simply plugged in, without further work steps must be provided. It is therefore not about a connection created in the manner of a dowel, in which after the actual insertion of the connecting element nor a spreading of the connecting element must be guaranteed.

Unter dem Begriff Einstecken wird hier ganz allgemein das Einstecken von Hand ohne ein zusätzliches Werkzeug oder das Einschlagen, Einschießen und/oder Eindrücken unter Verwendung eines entsprechenden Werkzeugs verstanden.The term insertion is understood here quite generally the insertion by hand without an additional tool or the impact, Einschießen and / or impressions using a corresponding tool.

Durch die Einteiligkeit wird erreicht, dass die Verbindung nicht erst umständlich durch die Montage des eigentlichen Verbindungselements aus mehreren Einzelteilen geschaffen werden muss. Außerdem ist der Verbindungsstift in der Öffnung des Grundkörpers gehalten. Ein Kontern oder dergleichen von der Rückseite des Grundkörpers ist damit ebenso entbehrlich, wie das Schaffen einer durchgehenden Öffnung. Ein Grundkörper mit einer Sacköffnung oder vorzugsweise eine Sackbohrung wäre vollkommen ausreichend. Die Öffnung kann bedarfsweise aber auch als Durchgangsöffnung ausgebildet sein.Due to the one-piece structure, it is achieved that the connection does not first have to be created by assembling the actual connecting element of several individual parts. In addition, the connecting pin is held in the opening of the base body. A counter or the like of the back of the body is thus dispensable, as well as the creation of a through opening. A basic body with a blind opening or preferably a blind bore would be perfectly adequate. The opening may, if necessary, also be formed as a passage opening.

Der Grundkörper und das Anbauteil sind Bestandteil eines Lastkraftwagens, Anhängers und/oder Aufliegers, insbesondere von einem offenen oder geschlossenen Aufbau eines Lastkraftwagens, Anhängers und/oder Aufliegers.The main body and the attachment are part of a truck, trailer and / or trailer, in particular of an open or closed structure of a truck, trailer and / or trailer.

Bei einer ersten Ausgestaltung der Verbindung kann vorgesehen sein, dass der Grundkörper eine Türe eines geschlossenen Aufbaus eines Lastkraftwagens, eines Anhängers und/oder eines Aufliegers und das Anbauteil ein Scharnier ist. Eine derartige Verbindung ist bevorzugt, weil sie einfach und schnell zu montieren ist und zudem die hohen Kräfte zum Halten der Türe am Scharnier jedenfalls teilweise aufnehmen kann.In a first embodiment of the connection can be provided that the main body is a door of a closed structure of a truck, a trailer and / or a trailer and the attachment is a hinge. Such a connection is preferred because it is easy and quick to assemble and in any case can partially absorb the high forces to hold the door on the hinge anyway.

Der Verbindungskopf ist verdrehsicher am, vorzugsweise im, Anbauteil gehalten. Damit ist eine vorgegebene Ausrichtung des Verbindungskopfs sichergestellt, die etwa eine dauerhafte Information für einen Benutzer darstellen kann. Bei einem geschlossenen Aufbau kann durch den Verbindungskopf, der verdrehsicher ist, eine Drehbewegung desselben vorzugsweise sowohl in die eine als auch in die andere Richtung verhindert werden. Für eine Anordnung des Verbindungskopfs in dem Anbauteil weist das Anbauteil vorzugsweise eine Aussparung zur wenigstens teilweisen Aufnahme des Verbindungskopfs auf.The connection head is held against rotation on, preferably in, attachment. This ensures a predetermined orientation of the connection head, which is about a permanent Can represent information for a user. In a closed structure can be prevented by the connecting head, which is against rotation, a rotational movement thereof preferably both in one direction and in the other direction. For an arrangement of the connection head in the attachment, the attachment preferably has a recess for at least partially receiving the connection head.

Durch die Verbindung kann beispielsweise auch ein zollsicherer Verschluss beispielsweise zwischen dem Scharnier und der Türe eines geschlossenen Aufbaus bereitgestellt werden. Diese Verschlüsse werden zollseitig gefordert, wenn ein unbefugtes und nicht erkennbares Öffnen des Aufbaus durch Dritte verhindert werden soll. Dann werden die Türen eines Lastkraftwagens oder Anhängers verplombt. Dies allein bietet allerdings noch keine ausreichende Sicherheit gegenüber einem unbefugten und unentdeckt bleibenden Zugriff auf die sich im geschlossenen Aufbau befindlichen Güter, sofern es möglich ist, die Scharniere einer Tür des Aufbaus zu lösen und anschließend wieder auf die ursprüngliche Weise an der Tür zu montieren.By way of example, the connection can also provide a duty-proof closure, for example between the hinge and the door of a closed structure. These closures are required on the customs side, if an unauthorized and unrecognizable opening of the structure by third parties should be prevented. Then the doors of a truck or trailer are sealed. However, this alone does not provide sufficient security against unauthorized and undetected permanent access to the goods located in the closed structure, if it is possible to release the hinges of a door of the structure and then mount again in the original way to the door.

Damit die Scharniere nicht unerkannt gelöst werden können, wird von Seiten des Zolls derzeit die Verwendung von so genannten asymmetrischen Schweißlösungen gefordert. Dabei sind die Scharniere mit handelsüblichen Schrauben an den Türen befestigt, wobei beispielsweise wenigstens ein Schraubenkopf in einer länglichen Aussparung eines Scharniers angeordnet ist. Ein ebenfalls längliches und mit der Innenkontur der Aussparung korrespondierendes Stahlplättchen ist auf den Schraubenkopf aufgesetzt und über eine kleine Durchgangsbohrung im Stahlplättchen mit dem Schraubenkopf verschweißt. Das Stahlplättchen liegt derart in der Aussparung des Scharniers, dass die mit dem Stahlplättchen verbundene Schraube nicht aus der Tür herausgedreht werden kann, ohne dass das Stahlplättchen vom Schraubenkopf abreißt oder jedenfalls erkennbar beschädigt wird.To ensure that the hinges can not be undetected, customs are currently calling for the use of so-called asymmetric welding solutions. The hinges are fastened with commercially available screws to the doors, for example, at least one screw head is arranged in an elongated recess of a hinge. A likewise elongated steel plate corresponding to the inner contour of the recess is placed on the screw head and welded to the screw head via a small through-hole in the steel plate. The steel plate lies in the recess of the hinge in such a way that the screw connected to the steel plate can not be unscrewed out of the door without the steel plate being torn off from the screw head or being noticeably damaged.

Eine Manipulation an dem Scharnier würde sich daher an einer Beschädigung des Stahlplättchens erkennen lassen oder einen hohen zeitlichen und apparativen Aufwand für das Wiederherstellen des ursprünglichen Zustands erfordern, da dazu nach dem Öffnen des Scharniers wieder ein Stahlplättchen auf den entsprechenden Schraubenkopf aufgeschweißt werden muss. Beides hält Unberechtige hinreichend sicher von einer Öffnung des zollsicher verschlossenen Aufbaus ab.A manipulation of the hinge would therefore be detectable from damage to the steel plate or require a great deal of time and equipment for restoring the original state, since a steel plate must be welded onto the corresponding screw head again after the hinge has been opened. Both unjustifiably safe from an opening of the duty-locked structure from.

Das Verschweißen des Stahlplättchens mit dem Schraubenkopf ist mit einer starken Erwärmung der Schraube und des Scharniers verbunden. Durch diese Erwärmung besteht die Gefahr, dass sich das Gefüge des Materials ändert und ein Oberflächenschutz der Schraube in Form einer Lackschicht, einer Verzinkung oder einer anderen Veredelung beschädigt wird. Derartige Beschädigungen lassen die Korrosionsneigung deutlich ansteigen. Ein weiterer Nachteil liegt darin, dass die Montage der Zollsicherungen eine geraume Zeit in Anspruch nimmt.The welding of the steel plate with the screw head is associated with a strong heating of the screw and the hinge. As a result of this heating, there is the risk that the structure of the material will change and a surface protection of the screw in the form of a lacquer layer, galvanizing or other finishing will be damaged. Such damage causes the tendency to corrosion increase significantly. Another disadvantage is that the installation of the customs fuses takes a long time.

Durch die Einteiligkeit des Verbindungselements kann auf den aus dem Stand der Technik bekannten Schweißvorgang verzichtet werden, was einerseits zu einer Beschleunigung der Montage und andererseits zu einer Vermeidung von Gefügeänderungen und Beschädigungen des Oberflächenschutzes in Folge erhöhter Temperaturen führt. Gleichzeitig kann das Verbindungselement auf Grund seiner Einteiligkeit aber nicht mehr, wie aus dem Stand der Technik bekannt, mit einer Türe des Aufbaus verschraubt werden.Due to the one-piece nature of the connecting element, it is possible to dispense with the welding process known from the prior art which on the one hand leads to an acceleration of the assembly and on the other hand to avoid structural changes and damage to the surface protection as a result of elevated temperatures. At the same time, however, the connecting element can no longer be screwed to a door of the structure due to its one-piece nature, as is known from the prior art.

In diesem Zusammenhang ist festzustellen, dass die verdrehsichere Anordnung des Verbindungselements im Scharnier weniger der Vermeidung der tatsächlichen Lösung der Verbindung als vielmehr der Detektion, bei welchem der verwendeten Befestigungselemente es sich um das die zollsichere Verbindung anzeigende Verbindungselement handelt, dient. Mit anderen Worten sind somit zollsichere und nicht zollsichere Verbindungen eindeutig voneinander zu unterscheiden. Zudem dient der Verbindungskopf dem Zoll zur Feststellung, ob die Verbindung unbeschädigt ist.In this connection, it should be noted that the non-rotatable arrangement of the connecting element in the hinge serves less to avoid the actual solution of the connection than to the detection in which the fastening element used is the connection element which indicates the secure connection. In other words, customs-friendly and non-customs-cleared connections must be clearly distinguished. In addition, the connection head serves the customs to determine whether the connection is undamaged.

Eine verdrehsichere Anordnung des Verbindungskopfs am Anbauteil, insbesondere am Scharnier, wird dadurch gewährleistet, dass der Verbindungskopf eine nicht rotationssymmetrische Außenkontur aufweist.A rotationally secure arrangement of the connecting head on the attachment, in particular on the hinge, is ensured by the fact that the connecting head has a non-rotationally symmetrical outer contour.

Eine einfache und kostengünstige Herstellung des Verbindungselements wird dabei beispielsweise dadurch gewährleistet, dass der Verbindungskopf eine im Wesentlichen längliche, vorzugsweise ovale Außenkontur, aufweist. Alternativ können selbstverständlich auch andere längliche Ausgestaltungen des Verbindungskopfs vorgesehen sein. Eine nicht rotationssymmetrische Außenkontur ergibt sich in diesem Zusammenhang auch für Verbindungsköpfe mit sternförmigen und rechteckigen Querschnitten oder dergleichen.A simple and cost-effective production of the connecting element is thereby ensured, for example, that the connecting head has a substantially elongated, preferably oval outer contour. Alternatively, of course, other elongated embodiments of the connecting head can be provided. A non-rotationally symmetrical outer contour results in this context also for connecting heads with star-shaped and rectangular cross-sections or the like.

Besonders zweckmäßig ist es, wenn der Verbindungskopf in einer Aussparung des Anbauteils vorgesehen ist und die Innenkontur dieser Aussparung im Wesentlichen oder jedenfalls abschnittsweise mit der Außenkontur des Verbindungskopfs korrespondiert. In diesem Fall kann auf einfache Weise sichergestellt werden, dass eine Verdrehung des Verbindungskopfs unabhängig von der Drehrichtung verhindert wird. Alternativ oder zusätzlich wäre es jedoch auch denkbar, dass das Anbauteil eine Anschlagfläche aufweist, an die der Verbindungskopf des Verbindungselements beim Drehen desselben anschlägt. Weiter vorzugsweise weist das Anbauteil bzw. das Scharnier zwei Anschlagflächen auf, so dass das Verbindungselement in beiden Drehrichtungen am Anbauteil anschlägt.It is particularly expedient if the connection head is provided in a recess of the attachment and the inner contour of this recess substantially or at least partially corresponds with the outer contour of the connection head. In this case, it can be ensured in a simple manner that a rotation of the connecting head is prevented, regardless of the direction of rotation. Alternatively or additionally, however, it would also be conceivable for the attachment to have an abutment surface against which the connecting head of the connecting element strikes during the rotation thereof. Further preferably, the attachment or the hinge on two abutment surfaces, so that the connecting element abuts in both directions of rotation on the attachment.

Bei einer weitern Ausgestaltung der Verbindung ist alternativ oder zusätzlich vorgesehen, dass das äußere, vom Verbindungsstift abgewandte Ende des Verbindungskopfs wenigstens flächenbündig in die Aussparung des Anbauteils eingelassenen, vorzugsweise in der Aussparung des Anbauteils versenkt, ist. Auf diese Weise wird sichergestellt, dass an dem Verbindungskopf nach der Montage des Verbindungselements nicht mehr ohne weiteres mit einen Werkzeug angegriffen werden kann, so dass ein unbefugtes Herausziehen des Verbindungselements vermieden wird. Dies ist besonders im Zusammenhang mit einem Zollverschluss eines geschlossenen Aufbaus von Vorteil.In a further embodiment of the connection is alternatively or additionally provided that the outer, remote from the connecting pin end of the connecting head embedded at least flush in the recess of the fixture, preferably recessed in the recess of the fixture is. In this way it is ensured that can no longer be easily attacked with a tool on the connection head after assembly of the connecting element, so that unauthorized withdrawal of the connecting element is avoided. This is particularly advantageous in connection with a bonded closure of a closed structure.

Das Verbindungselement ist vorzugsweise kraftschlüssig, formschlüssig, reibschlüssig und/oder stoffschlüssig in der Öffnung des Grundkörpers gehalten. Auf diese Weise ist es möglich, das Verbindungselement, insbesondere den Verbindungsstift, in die Öffnung des Grundkörpers einzubringen, ohne dass der Verbindungsstift dabei um seine eigene Achse gedreht werden müsste. Das Verbindungselement kann also einfach und schnell eingeschoben bzw. eingeschlagen werden, wodurch sich die notwendige Montagezeit erheblich verkürzt.The connecting element is preferably non-positively, positively, frictionally and / or cohesively held in the opening of the body. In this way it is possible to introduce the connecting element, in particular the connecting pin, in the opening of the base body, without the connecting pin would have to be rotated about its own axis. The connecting element can therefore be inserted and / or driven in easily and quickly, which considerably shortens the necessary assembly time.

Bei einer besonders bevorzugten Ausgestaltung weist der Verbindungsstift eine Rändelung zum Verbinden des Verbindungselements mit der Öffnung des Grundkörpers auf. Diese Rändelung erlaubt beispielsweise einerseits das Einschlagen des Verbindungselements in den Grundkörper ohne eine Verdrehung des Verbindungselements und gleichzeitig die feste kraftschlüssige und ggf. formschlüssige Fixierung des Verbindungsstifts im Anbauteil, was insbesondere für die Verbindung zwischen Scharnier und Türe des geschlossenen Aufbaus vorteilhaft ist. Das Verbindungselement lässt sich daher nicht mehr ohne weiteres wieder entfernen. Alternativ könnte die Rändelung auch derart ausgebildet sein, dass der Verbindungsstift lediglich reibschlüssig in der Türe gehalten wird, wobei jedoch geringere Auszugskräfte realisiert werden können. Auch in diesem Fall kann die Verbindung nicht ohne weiteres wieder gelöst werden. Ferner ist es denkbar, wenn auch weniger bevorzugt, dass die Rändelung des Verbindungsstifts dem festen Einkleben des Verbindungselements im Grundkörper dient.In a particularly preferred embodiment, the connecting pin has a knurling for connecting the connecting element to the opening of the main body. This knurling allows, for example, on the one hand, the turning of the connecting element in the body without twisting the connecting element and at the same time the firm non-positive and possibly positive fixing of the connecting pin in the attachment, which is particularly advantageous for the connection between the hinge and door of the closed structure. Therefore, the connecting element can not be easily removed again. Alternatively, the knurling could also be designed such that the connecting pin is held only frictionally in the door, but lower extraction forces can be realized. Also in this case, the connection can not be solved easily again. Furthermore, it is conceivable, although less preferred, that the knurling of the connecting pin serves for firmly gluing the connecting element in the base body.

Die Rändelung kann unterschiedlich ausgebildet sein. Jedenfalls weist die Rändelung jedoch wenigstens einen Vorsprung auf und unterscheidet sich so von dem im Wesentlichen glatten Rest des Verbindungsstifts.The knurling can be designed differently. In any case, however, the knurling has at least one projection and thus differs from the substantially smooth remainder of the connecting pin.

In diesem Zusammenhang bietet es sich weiter an, wenn die Rändelung eine Mehrzahl von voneinander in Längserstreckung des Verbindungsstifts beabstandeten Rippen aufweist. Derartige Rippen halten hohen Auszugskräften stand. Sofern dies hinsichtlich der Auszugskräfte ausreichend ist, kann auch nur eine einzelne Rippe vorgesehen sein.In this context, it further lends itself to when the knurling has a plurality of ribs spaced from each other in the longitudinal extent of the connecting pin. Such ribs withstand high pull-out forces. If this is sufficient in terms of pull-out forces, only a single rib can be provided.

Wenn die Rippen sich jeweils in einer Ebene senkrecht zur Längserstreckung des Verbindungsstifts oder in einer Ebene näherungsweise senkrecht zur Längserstreckung des Verbindungsstifts erstrecken, können besonders hohe Auszugskräfte von der Verbindung aufgenommen werden. Die beschriebene Anordnung der Rippen erlaubt zudem ein Umgreifen der Rippen durch den Grundkörper nach dem Einbringen des Verbindungselements, so dass auf diese Weise ein Formschluss und/oder ein Kraftschluss etabliert werden kann.If the ribs each extend in a plane perpendicular to the longitudinal extent of the connecting pin or in a plane approximately perpendicular to the longitudinal extension of the connecting pin, particularly high pull-out forces can be absorbed by the connection. The described arrangement of the ribs also allows embracing the ribs through the body after the introduction of the connecting element, so that in this way a positive connection and / or a frictional connection can be established.

Um einerseits das Verbindungselement ohne übermäßigen Kraftaufwand in die Öffnung des Grundkörpers einbringen zu können und andererseits ein Lösen des Verbindungselements zu vermeiden, können die Flanken der einzelnen Rippen unterschiedliche Neigungen aufweisen. Die Neigung der dem freien Ende des Verbindungsstifts zugewandten Flanke der Rippen ist dabei flacher als die Neigung der dem Verbindungskopf zugewandten Flanken der Rippen. Mit anderen Worten sind die Flanken in Richtung auf das freie Ende des Verbindungsstifts abgeschrägt. Die übrigen Flanken erstrecken sich dagegen vorzugsweise senkrecht zur Längserstreckung des Verbindungsstifts oder sind gar zum Verbindungskopf hin geneigt. Die Rippen bilden so letztlich eine Reihe von Widerhaken.On the one hand to be able to bring the connecting element without excessive force in the opening of the body and on the other hand to avoid loosening of the connecting element, the flanks of the individual ribs may have different inclinations. The inclination of the free end of the connecting pin facing edge of the ribs is flatter than the inclination of the connecting head facing flanks of the ribs. In other words, the flanks are chamfered towards the free end of the connecting pin. The remaining flanks extend On the other hand, preferably perpendicular to the longitudinal extent of the connecting pin or even inclined to the connection head. The ribs ultimately form a series of barbs.

Bei einer besonders bevorzugten Ausgestaltung des Aufbaus ist der Verbindungsstift in ein Sackloch des Grundkörpers, vorzugsweise der Türe, insbesondere eines speziellen Beschlags der Türe, eingeführt. Auf diese Weise wird verhindert, dass der Verbindungskopf herausgefräst und der Verbindungsstift mit Gewalt aus dem Grundkörper herausgeschlagen, beispielsweise in den geschlossenen Aufbau hineingeschlagen, wird. In einem solchen Falle könnte die Tür geöffnet und anschließend durch Einbringen eines neuen Verbindungselements derart verschlossen werden, dass die zwischenzeitliche Öffnung nachträglich nicht mehr ohne weiteres erkennbar ist.In a particularly preferred embodiment of the structure of the connecting pin in a blind hole of the body, preferably the door, in particular a special fitting of the door, introduced. In this way it is prevented that the connecting head milled out and the connecting pin forcibly knocked out of the body, for example, knocked into the closed structure, is. In such a case, the door could be opened and then closed by introducing a new connection element such that the interim opening is no longer readily recognizable.

Beim Einbringen des Verbindungsstifts in das Sackloch kann es vorkommen, dass die zuvor in dem Sackloch befindliche Atmosphäre so stark komprimiert wird, dass das Einbringen des Verbindungsstifts in das Sackloch nicht oder nur mit einem sehr hohen Kraftaufwand durchgeführt werden kann. Damit das Verbindungselement ohne erhöhten Kraftaufwand auch in einem Sackloch positioniert werden kann, kann zwischen dem Verbindungsstift und dem Sackloch wenigstens ein Strömungskanal zum Entweichen von durch den Verbindungsstift verdrängter Atmosphäre aus dem Sackloch vorgesehen sein.When inserting the connecting pin in the blind hole, it may happen that the previously located in the blind hole atmosphere is compressed so much that the introduction of the connecting pin in the blind hole can not be performed or only with a very high force. So that the connecting element can also be positioned in a blind hole without increased expenditure of force, at least one flow channel for the escape of the atmosphere displaced by the connecting pin from the blind hole can be provided between the connecting pin and the blind hole.

Dies lässt sich in konstruktiv besonders einfacher Weise dadurch realisieren, dass die Rippen entlang des Umfangs des Verbindungsstifts jeweils wenigstens eine Aussparung oder Unterbrechung aufweisen. Damit führen die Rippen nicht zu einem Verschluss des Sacklochs gegenüber der komprimierten Atmosphäre innerhalb des Sacklochs. Die komprimierte Atmosphäre kann stattdessen durch die Aussparungen oder Unterbrechungen in den Rippen quasi entlang eines auf diese Weise gebildeten Strömungskanals entweichen.This can be realized in a structurally particularly simple manner in that the ribs have at least one recess or interruption along the circumference of the connecting pin. This will not cause the ribs a shutter of the blind hole against the compressed atmosphere within the blind hole. Instead, the compressed atmosphere may escape through the recesses or breaks in the fins, more or less along a flow channel formed in this manner.

In der Fig. 1 ist ein Lastkraftwagen L mit einem Auflieger A, einem sogenannten Trailer, dargestellt, der einen geschlossenen Aufbau 1 in Form eines Kofferaufbaus trägt. Alternativ könnte es sich vorliegend auch um einen Auflieger in Form einer Pritsche handeln. Derartige Pritschen weisen im Gegensatz zu dem dargestellten Kofferaufbau keine festen Seitenwände, sondern lediglich Planen auf. Auch Pritschen weisen bedarfsweise rückwärtige Türen auf, die über Scharniere an einem Rückwandrahmen befestigt sind.In the Fig. 1 is a truck L with a trailer A, a so-called trailer, shown, which carries a closed structure 1 in the form of a box body. Alternatively, this could also be a semi-trailer in the form of a bunk. Such platforms have in Contrary to the illustrated box body no fixed side walls, but only plan on. Also flatbeds have, if necessary, rear doors, which are fastened by hinges to a rear wall frame.

Die Darstellung eines Aufliegers ist, wenn ein solcher auch grundsätzlich bevorzugt ist, als beispielhaft anzusehen. Anstelle eines Aufbaus eines Aufliegers könnte es sich alternativ auch um den Aufbau eines Lastkraftwagens oder eines gewöhnlichen Anhängers handeln.The representation of a semitrailer, if one is also generally preferred, is to be regarded as exemplary. Alternatively, a structure of a trailer could alternatively be the construction of a truck or a conventional trailer.

Der dargestellte und insoweit bevorzugte geschlossene Aufbau 1 weist ein Dachpaneel 2, zwei Seitenwandpaneele 3, ein nicht im Einzelnen dargestelltes Bodenpaneel sowie eine Türen 4 aufweisende Rückwand 5 auf. Die Türen 4 der Rückwand 5 sind mit Hilfe von Scharnieren 6 an einem Rückwandrahmen 7, der teilweise durch die Seitenwandpaneele 3 gebildet sein kann, befestigt.The illustrated and so far preferred closed structure 1 has a roof panel 2, two side wall panels 3, a not shown in detail floor panel and a door 4 having the rear wall 5. The doors 4 of the rear wall 5 are fixed by means of hinges 6 to a rear wall frame 7, which may be formed in part by the side wall panels 3.

Das in der Fig. 1 dargestellte, ein Scharnier 6 umfassende Detail II ist in der Fig. 2 vergrößert dargestellt. Das Scharnier 6 ist über eine entsprechende Aufhängung an dem Rückwandrahmen 7 bzw. dem Seitenwandpaneel 3 befestigt. Die andere Hälfte des Scharniers 6 ist über zwei Schrauben 8 mit der Türe 4 verbunden, wobei die Schrauben 8 runde Schraubenköpfe aufweisen, die in korrespondierenden kreisförmigen Aussparungen 9 des Scharniers 6 eingelassen sind. Zwischen den Schrauben 8 ist ein Verbindungselement 10 angeordnet, das ebenfalls das Scharnier 6 fest mit der Türe 4 verbindet. Auch der Verbindungskopf 11 des Verbindungselements 10 ist in einer korrespondierenden Aussparung 12 des Scharniers 6 aufgenommen. Im Unterschied zu den Schraubenköpfen ist der Verbindungskopf 11 des Verbindungselements 10 länglich, und zwar oval, ausgebildet. Da der Verbindungskopf 11 des Verbindungselements 10 in einer korrespondierend, das heißt oval, ausgebildeten Aussparung 12 angeordnet ist, wird der Verbindungskopf 11 und damit das gesamte Verbindungselement 10 verdrehsicher im Scharnier 6 fixiert. Darüber hinaus ist das Verbindungselement 10 auf Grund der ovalen Ausgestaltung des Verbindungskopfs 11 von außen ohne Weiteres als Zollsicherung zu erkennen und damit von den gewöhnlichen Schraubverbindungen zu unterscheiden. Wie es bei gewöhnlichen Schrauben der Fall ist, ist das Verbindungselement 10 ebenfalls einteilig ausgebildet, insbesondere aus einem Rohling durch spanende Bearbeitung herausgearbeitet.That in the Fig. 1 shown, a hinge 6 comprehensive detail II is in the Fig. 2 shown enlarged. The hinge 6 is fastened via a corresponding suspension to the rear wall frame 7 or the side wall panel 3. The other half of the hinge 6 is connected by two screws 8 with the door 4, wherein the screws 8 have round screw heads, which are embedded in corresponding circular recesses 9 of the hinge 6. Between the screws 8, a connecting element 10 is arranged, which also connects the hinge 6 fixed to the door 4. Also, the connecting head 11 of the connecting element 10 is received in a corresponding recess 12 of the hinge 6. Unlike the Screw heads, the connecting head 11 of the connecting element 10 is elongated, namely oval, formed. Since the connecting head 11 of the connecting element 10 is arranged in a corresponding, that is oval, recess 12, the connecting head 11 and thus the entire connecting element 10 is fixed against rotation in the hinge 6. In addition, due to the oval configuration of the connecting head 11, the connecting element 10 can be readily recognized from the outside as a customs safeguard and thus distinguished from the usual screwed connections. As is the case with ordinary screws, the connecting element 10 is also formed in one piece, in particular machined out of a blank by machining.

Ein weiterer Unterschied zwischen dem in der Fig. 2 dargestellten Verbindungskopf 11 und den ebenfalls dargestellten Schraubenköpfen liegt darin, dass der Verbindungskopf 11 keine besonderen Flächen zum Angreifen eines Schraubwerkzeugs aufweist. Entsprechende Flächen sind nicht erforderlich, da das Verbindungselement 10 in das Scharnier 6 eingesteckt bzw. eingeschlagen und nicht eingeschraubt wird.Another difference between in the Fig. 2 illustrated connecting head 11 and the screw heads also shown is that the connecting head 11 has no special surfaces for engaging a screwing. Corresponding surfaces are not required because the connecting element 10 is inserted or wrapped in the hinge 6 and not screwed.

Auf welche Weise die Türe 4 über das Verbindungselement 10 mit dem Scharnier verbunden ist, ist insbesondere in der Fig. 3 dargestellt. Die Fig. 3 zeigt einen horizontalen Schnitt in Höhe des Verbindungselements 10 durch den in der Fig. 2 dargestellten Teil der Rückwand 5. Die in der Fig. 3 dargestellte und insoweit bevorzugte Türe 4 weist ein äußeres Beschlagelement 13 auf, das an dem Scharnier 6 anliegt. Das Beschlagelement 13 dient der lokalen Versteifung der Türe 4 und weist ein Sackloch 14 in Form einer Sackbohrung auf, in die das Verbindungselement 10 eingeschoben ist. Am Übergang zwischen dem Verbindungsstift 15 und dem Verbindungskopf 11 weist das dargestellte und insoweit bevorzugte Verbindungselement 10 eine Querschnittserweiterung auf, an der sich das Verbindungselement 10 gegenüber dem Scharnier 6 abstützt und das Scharnier 6 so dauerhaft in Anlage am Beschlagelement 13 der Türe 4 hält.The way in which the door 4 is connected to the hinge via the connecting element 10 is particularly in the Fig. 3 shown. The Fig. 3 shows a horizontal section at the level of the connecting element 10 by in the Fig. 2 shown part of the back wall 5. The in the Fig. 3 illustrated and so far preferred door 4 has an outer fitting element 13 which bears against the hinge 6. The fitting element 13 serves for the local stiffening of the door 4 and has a blind hole 14 in the form of a blind bore into which the connecting element 10 is inserted. At the transition between the connecting pin 15 and the connecting head 11, the illustrated and so far preferred connecting element 10 has a cross-sectional widening on which the connecting element 10 is supported relative to the hinge 6 and the hinge 6 so permanently in contact with the fitting element 13 of the door 4 holds.

Ein unbeabsichtigtes Trennen der Verbindung wird durch die am freien Ende des Verbindungsstifts 15 vorgesehene Rändelung 16 erreicht, die formschlüssig in das Beschlagelement 13 der Türe 4 eingreift. Selbst wenn bei dem dargestellten und insoweit bevorzugten Ausführungsbeispiel der Verbindungskopf 11 des Verbindungselements 10 abgefräst werden würde, so könnte der verbleibende Verbindungsstift 15 nicht ohne Weiteres durch die Rückwand 5 in den Innenraum des Kofferaufbaus hineingedrückt bzw. hineingeschlagen werden, da das freie Ende des Verbindungsstifts 15 des Verbindungselements 10 im Sackloch 14 des Beschlagelements 13 der Türe 4 angeordnet ist.An unintentional disconnection of the connection is achieved by the provided at the free end of the connecting pin 15 knurling 16 which engages positively in the fitting element 13 of the door 4. Even if in the illustrated preferred embodiment, the connecting head 11 of the connecting element 10 would be milled off, the remaining connecting pin 15 could not be easily pushed or pushed into the interior of the box body by the rear wall 5, since the free end of the connecting pin 15th of the connecting element 10 in the blind hole 14 of the fitting element 13 of the door 4 is arranged.

Das in der Fig. 3 dargestellte Verbindungselement 10 ist vergrößert in der Fig. 4 dargestellt. Der Verbindungskopf 11 des Verbindungselements 10 ist leicht gegenüber der Längserstreckung des Verbindungsstifts 15 geneigt. Diese Neigung des Verbindungskopfs 11 gegenüber dem Verbindungsstift 15 lässt sich in weiteren Bereichen variieren, ohne die Funktionalität des Verbindungselements 10 im Zusammenhang mit dem Scharnier 6 zu beeinträchtigen. Die Rändelung 16 im Bereich des freien Endes des Verbindungsstifts 15 wird durch eine Vielzahl parallel angeordneter Rippen 17 gebildet, die jeweils in einer Ebene im Wesentlichen senkrecht zur Längserstreckung des Verbindungsstifts 15 umlaufend angeordnet sind.That in the Fig. 3 illustrated connecting element 10 is enlarged in the Fig. 4 shown. The connecting head 11 of the connecting element 10 is slightly inclined with respect to the longitudinal extent of the connecting pin 15. This inclination of the connecting head 11 with respect to the connecting pin 15 can be varied in other areas, without affecting the functionality of the connecting element 10 in connection with the hinge 6. The knurling 16 in the region of the free end of the connecting pin 15 is formed by a plurality of parallel ribs 17, each in a plane substantially perpendicular to Longitudinal extent of the connecting pin 15 are arranged circumferentially.

Um das Verbindungselement 10 ohne größeren Kraftaufwand in die Türe 4 bzw. in das Beschlagelement 13 der Türe 4 einbringen zu können, sind die dem freien Ende des Verbindungsstifts 15 zugewandten Flanken 18 der Rippen 17 abgeschrägt, wobei die Flanken 18 weg von dem freien Ende des Verbindungsstifts 15 geneigt sind.In order to bring the connecting element 10 without much effort in the door 4 and in the fitting element 13 of the door 4, the free end of the connecting pin 15 facing flanks 18 of the ribs 17 are chamfered, the flanks 18 away from the free end of the Connecting pin 15 are inclined.

Die gegenüberliegenden, dem Verbindungskopf 11 zugewandten Flanken 19 der Rippen 17 sind bei dem dargestellten und insoweit bevorzugten Verbindungselement 10 im Wesentlichen senkrecht zur Längserstreckung des Verbindungsstifts 15 ausgerichtet. Die Rippen 17 stellen daher einzelne Widerhaken dar, die sich in das Material des Beschlagelements 13 der Türe 4 verkrallen. Die Verbindung zwischen dem Beschlagelement 13 und dem Verbindungselement 10 kann daher sehr hohe Auszugskräfte aufnehmen.The opposite, the connecting head 11 facing flanks 19 of the ribs 17 are aligned in the illustrated and so far preferred connecting element 10 substantially perpendicular to the longitudinal extent of the connecting pin 15. The ribs 17 therefore represent individual barbs, which dig into the material of the fitting element 13 of the door 4. The connection between the fitting element 13 and the connecting element 10 can therefore absorb very high pull-out forces.

Die Rippen 17 des dargestellten und insoweit bevorzugten Verbindungselements 10 weisen jeweils über ihren Umfang vier Unterbrechungen 20 auf, wobei die Unterbrechungen 20 der Rippen 17 jeweils fluchtend in der Längserstreckung des Verbindungsstifts 15 ausgerichtet sind. In Folge dieser Unterbrechungen 20, die auch alternativ als Aussparungen ausgebildet und nicht fluchtend ausgerichtet sein können, ergibt sich zwischen dem Verbindungselement 10 und dem Beschlagelement 13 der Türe 4 ein Strömungskanal 21, durch den beim Einschieben des Verbindungsstifts 15 in das Sackloch 14 komprimierte und verdrängte Atmosphäre, insbesondere Luft, nach außen entweichen kann. In Folge dieses Strömungskanals 21 kann sich innerhalb des Sacklochs 14 kein nennenswerter Überdruck bilden, der sich negativ auf die zum Einbringen des Verbindungselements 10 erforderlichen Kräfte auswirken würde. Ein derartiger Strömungskanal 21 ist beispielhaft in der Fig. 3 dargestellt.The ribs 17 of the illustrated and so far preferred connecting element 10 each have four interruptions 20 over their circumference, wherein the interruptions 20 of the ribs 17 are aligned in each case in the longitudinal extension of the connecting pin 15. As a result of these interruptions 20, which may alternatively be formed as recesses and not aligned, resulting between the connecting element 10 and the fitting element 13 of the door 4, a flow channel 21, compressed by the insertion of the connecting pin 15 in the blind hole 14 and displaced Atmosphere, especially air, can escape to the outside. As a result of this flow channel 21 can form no appreciable overpressure within the blind hole 14, which would adversely affect the forces required for the introduction of the connecting element 10. Such a flow channel 21 is exemplary in the Fig. 3 shown.

Bei dem in der Fig. 5 dargestellten und insoweit bevorzugten Verbindungselement 10 weisen die jeweiligen Rippen 17 vier Unterbrechungen 20 auf. Man könnte daher auch alternativ jede einzelne Rippe 17 als durch vier Teilrippen gegeben ansehen. Alle vier Unterbrechungen 20 jeder Rippe 17 sind in Längserstreckung des Verbindungsstifts 15 hintereinander ausgerichtet. Dies ist zwar nicht zwingend erforderlich, ermöglicht jedoch eine schnelle und sichere Entlüftung des Sacklochs 14 beim Einbringen des Verbindungsstifts 15. Ferner ist in der Fig. 5 noch einmal die bevorzugte Ausgestaltung des Verbindungskopfs 11 mit einer ovalen Kontur in einer Ebene senkrecht zur Längserstreckung des Verbindungsstifts 15 dargestellt.In the in the Fig. 5 illustrated and so far preferred connecting element 10, the respective ribs 17 four interruptions 20. One could therefore also alternatively see each individual rib 17 as given by four sub-ribs. All four interruptions 20 of each rib 17 are aligned one behind the other in the longitudinal extent of the connecting pin 15. Although this is not absolutely necessary, but allows a quick and safe venting of the blind hole 14 during insertion of the connecting pin 15. Further, in the Fig. 5 Again, the preferred embodiment of the connecting head 11 with an oval contour in a plane perpendicular to the longitudinal extension of the connecting pin 15 is shown.

Nicht im Einzelnen dargestellt ist, dass das dargestellte und insoweit bevorzugte Verbindungselement 10 eine Beschichtung aufweist. Die Beschichtung ist am gesamten Verbindungselement 10 vorgesehen, obwohl auch nur abschnittsweise angebrachte Beschichtungen möglich wären. In dem Verbindungsbereich zwischen Verbindungselement 10 und Türe 4 sowie Scharnier 6 verhindert die Beschichtung auf die im Stand der Technik bekannte Art das Auftreten von Kontaktkorrosion. An der Oberseite des Verbindungskopfs 11 erfüllt die Beschichtung optische Zwecke und verhindert ebenfalls Korrosion. Die Oberseite des Verbindungskopfs 11 kann bereits vor dem Verbinden mit der Türe 4 endgültig bearbeitet sein, da diese Oberfläche beim Montieren der Zollsicherung weder durch Eindrehen, Verschweißen oder dergleichen beschädigt wird.It is not shown in detail that the illustrated and so far preferred connecting element 10 has a coating. The coating is provided on the entire connecting element 10, although only partially applied coatings would be possible. In the connection region between connecting element 10 and door 4 and hinge 6, the coating prevents the occurrence of contact corrosion in the manner known in the prior art. At the top of the connecting head 11, the coating performs optical purposes and also prevents corrosion. The upper side of the connecting head 11 can already be finished before connecting to the door 4, since these Surface is not damaged by screwing, welding or the like when mounting the customs fuse.
