Ein solches Kuppelstück ist aus der DE 102 38 895 A1 bzw. der korresponierenden WO 2004/020316 A1 bekannt.Such a coupling piece is from the DE 102 38 895 A1 or the corresponding WO 2004/020316 A1 known.

Seit Container sich zum Transport von Gütern wegen des mit ihnen möglichen schnellen Güterumschlags durchgesetzt haben, wird ständig daran gearbeitet, das Verzurren der Container an Bord von Schiffen zu verbessern. Neben Fragen der Sicherheit wurde auch ständig daran gearbeitet, den Umschlag der Container in den Häfen zu beschleunigen, um die Liegezeiten der Schiffe zu verkürzen. Dieses betrifft insbesondere die an Deck von Schiffen transportierten Container. Diese wurden zunächst mit manuellen Twistlocks gesichert, welche sowohl beim Beladen des Schiffes mit den Containern als auch beim Löschen (Entladen) manuell betätigt werden mussten. Dieses war nicht nur zeitaufwändig, sondern auch noch die Anwesenheit der Stauer an Deck des Schiffes während des Verladenes der Container erforderlich, sodass diese gezwungen waren, sich unter schwebenden Lasten aufzuhalten. Zudem ist die Oberfläche der Container, die von den Stauern begangen werden musste, bei ungünstigen Witterungsverhältnissen sehr glatt. Deshalb ist dieses mit erheblichen Gefahren für die Stauer verbunden, sodass es in den 90er Jahren verboten wurde, dass Stauer sich während des Beladens des Schiffes mit Containern im Bereich der Bay, die gerade beladen wird, aufhalten.Since containers have prevailed for the transport of goods because of the possible with them fast cargo handling, is constantly working to improve the lashing of containers on board ships. In addition to safety issues, work has also been underway to accelerate the handling of containers at ports to reduce the time spent on ships. This concerns in particular the containers transported on deck of ships. These were initially secured with manual twistlocks, which both when loading the ship had to be operated manually with the containers as well as during unloading. Not only was this time consuming, but the stevedores were also required to be on deck of the ship during container loading, forcing them to be under suspended loads. In addition, the surface of the container, which had to be committed by the Stauern, in very bad weather conditions very smooth. Therefore, this is associated with significant dangers for the stevedores, so it was banned in the 90s that stevedores while loading the ship with containers in the Bay area, which is currently being loaded.

Ein erster Schritt, die Sicherheit für die Stauer zu erhöhen und den Containerumschlag in den Häfen zu beschleunigen, waren semiautomatische Twistlocks (Semi Automatic Twistlock - SAT). Semiautomatische Twistlocks verkuppeln beim Absetzen des oberen Containers auf dem unteren Container automatisch, sodass die übereinander gestapelten Container fest miteinander gekuppelt sind. Zum Löschen der Container müssen die semiautomatischen Twistlocks jedoch durch die Stauer manuell geöffnet werden. Dieses ist für die Stauer sehr sicher, da sie, sobald das Schiff im Hafen liegt, sämtliche Twistlocks der zu löschenden Containern öffnen und dann das Schiff verlassen können, bevor die Container vom Bord gehievt werden. Die Stauer brauchen sich also nicht mehr unter schwebenden Lasten aufzuhalten. Das manuelle Entkuppeln der Twistlocks ist aber immer noch sehr zeitaufwändig.A first step to increase the safety of the stevedores and to accelerate the container handling in the ports were semiautomatic twistlocks (Semi Automatic Twistlock - SAT). Semiautomatic twistlocks automatically lock when the upper container is placed on the lower container so that the stacked containers are firmly coupled together. However, to clear the containers, the semi-automatic twistlocks must be manually opened by the stevedores. This is very safe for the stevedores, since, once the ship is in port, they can open all the twistlocks of the containers to be dropped and then leave the ship before the containers are hoisted off the shelf. The stevedores no longer need to be under suspended loads. The manual uncoupling of the twistlocks is still very time consuming.

Durch die eingangs genannte DE 102 38 895 A1 bzw. der korresponierenden WO 2004/020316 A1 wurde ein vollautomatischer Twistlock (Fully Automatic Twistlock - FAT) geschaffen, welcher sowohl beim Absetzen des oberen Containers auf dem unteren Containern vollautomatisch verkuppelt als auch beim Löschen der Container vollautomatisch wieder entkuppelt. Ein weitere, ähnlich aufgebauter vollautomatischer Twischtlock ist aus der DE 10 2004 042 435 A1 bekannt. Das Staupersonal ist nur noch erforderlich, um die vollautomatischen Twistlocks am Kai in die unteren Eckbeschläge des oberen Containers einzusetzen, bevor der Container an Bord des Schiffes gehievt wird, bzw. die Twistlocks nach dem Hieven des Containers von Bord des Schiffes wieder am Kai zu entfernen.By the aforementioned DE 102 38 895 A1 or the corresponding WO 2004/020316 A1 A fully automatic Twistlock (Fully Automatic Twistlock - FAT) was created, which automatically disengages both when depositing the upper container on the lower container and automatically decoupling it when deleting the container. Another, similarly constructed fully automatic Twishlock is from the DE 10 2004 042 435 A1 known. The congestion staff is now only required to insert the fully automatic twist locks on the quay in the lower corner fittings of the upper container before the container is hoisted on board the ship, or to remove the twist locks after the container has been lifted from the ship again on the quayside ,

Dass der vollautomatische Twistlock nach der DE 102 38 895 A1 bzw. der korresponierenden WO 2004/020316 A1 die übereinander gestapelten Container während des Seetransports sicher verkuppelt, liegt an seiner seitlich angeordneten Kupplungsnase. Diesem vollautomatischen Twistlock liegt die Erkenntnis zu Grunde, dass Stampfbewegungen des Schiffes kaum Vertikalbeschleunigungen an den Containern zur Folge haben, sodass hier kaum oder keine Abhebekräfte auf die Container wirken. Beim Rollen des Schiffes treten zwar erhebliche Vertikalbeschleunigungen auf. Es wirken dann aber zwischen zwei übereinander gestapelten Containern auf einer Längsseite Druckkräfte (Druckseite), während auf der anderen Längsseite Zugkräfte (Zugseite) wirken. Aufgrund der Gestaltung des vollautomatischen Twistlocks verhindern die auf der Druckseite angeordneten Twistlocks, dass die beiden übereinander gestapelten Container horizontal gegeneinander verrutschen können. Dadurch wird sichergestellt, dass die Kupplungsnasen der auf der Zugseite angeordneten Twistlocks nicht entkuppeln können. Wird der obere Container jedoch im Hafen durch einen Kran angehoben, wirken an allen vier Twistlocks Zugkräfte, sodass ein Entkuppeln möglich ist.That the fully automatic twistlock after the DE 102 38 895 A1 or the corresponding WO 2004/020316 A1 The containers stacked on top of each other during sea transport are safely coupled to their laterally arranged coupling nose. This fully automatic twistlock is based on the finding that ramming movements of the ship hardly cause vertical accelerations on the containers, so that hardly or no lifting forces act on the containers. While rolling the ship, significant vertical accelerations occur. But then act between two stacked containers on one longitudinal side compressive forces (pressure side), while on the other longitudinal side tensile forces (tension side) act. Due to the design of the fully automatic twist lock, the twistlocks arranged on the pressure side prevent the two stacked containers from slipping horizontally against one another. This ensures that the coupling lugs can not decouple the arranged on the tension side twistlocks. However, if the upper container is lifted by a crane in the harbor, all four twistlocks have a tensile force, which means they can be uncoupled.

Dennoch wird befürchtet, dass es auf bestimmten Stauplätzen, zum Beispiel in einer vorderen oder hinteren Bay, unter ganz bestimmten Bedingungen doch dazu kommen kann, dass an allen vier Twistlocks Zugkräfte auftreten und es deshalb zu einem ungewollten Entkuppeln kommen könnte. Um dieses zu vermeiden, wurden durch die DE 10 2011 002 518 B3 oder die DE 20 2004 017 252 U1 vollautomatische Twistlocks mit zwei einander gegenüberliegenden Kupplungsnasen vorgeschlagen. Beide Schriften zeigen jeweils einen solchen vollautomatischen Twistlock, bei dem die beiden Kupplungsnasen auf unterschiedlichen Höhen angeordnet sind. Dieses führt sowohl beim Verkuppeln als auch beim Entkuppeln zu einer "Z-Bewegung", welche als nachteilig empfunden wird, da sie zu einem Verhaken/Verklemmen beim Be- bzw. Entladevorgang führen kann.Nevertheless, it is feared that in certain stowage areas, for example in a front or rear bay, under very specific conditions it can happen that on all four twistlocks tensile forces occur and it could therefore come to an unwanted uncoupling. To avoid this, were by the DE 10 2011 002 518 B3 or the DE 20 2004 017 252 U1 fully automatic twistlocks with two opposite coupling lugs proposed. Both documents each show such a fully automatic twistlock in which the two coupling lugs are arranged at different heights. This leads both during coupling as well as during decoupling to a "Z-movement", which is perceived as disadvantageous, since it can lead to a hooking / jamming during loading and unloading.

Hiervon ausgehend liegt der Erfindung das Problem zu Grunde, das eingangs genannte Kuppelstück derart weiterzubilden, dass es zwei übereinander gestapelte Container auch bei reinen Zugkräften sicher verkuppelt und "Z-Bewegungen" beim Ver- und Entkuppeln verhindert.Proceeding from this, the invention is based on the problem of further developing the coupling piece mentioned above in such a way that it reliably couples two containers stacked on top of one another, even in the case of pure tensile forces, and prevents "Z movements" during coupling and uncoupling.

Zur Lösung dieses Problems ist das erfindungsgemäße Kuppelstück dadurch gekennzeichnet, dass der untere Kupplungsvorsprung in der Rückwand eine sich nutartig über die gesamte Länge des unteren Kupplungsvorsprungs erstreckende Ausnehmung aufweist.To solve this problem, the coupling piece according to the invention is characterized in that the lower coupling projection in the rear wall has a groove extending over the entire length of the lower coupling projection recess.

Das erfindungsgemäße Kuppelstück ist also im Wesentlichen wie ein vollautomatisches Twistlock nach der DE 102 38 895 A1 bzw. der korresponierenden WO 2004/020316 A1 ausgebildet. Es ist jedoch in der Rückwand des Twistlock eine nutartige Ausnehmung vorgesehen, wobei der Abstand einer freien Kante der Kupplungsnase zur Rückwand kleiner oder gleich der Breite eines oberen Langlochs im oberen Eckbeschlag ist. Hierdurch kommt es beim Ver- und Entkuppeln nicht mehr zur einer "Z-Bewegung". Sollte die Kupplungsnase auf der Zugseite trotz aller Vorkehrungen aus dem zugehörigen Eckbeschlag gleiten, also hinter der Kante des oberen Langlochs dieses Eckbeschlages freikommen, rutscht der obere Container auf dem unteren Container horizontal in eine Richtung, die der Richtung, in welche die Kupplungsnase zeigt, entgegen gesetzt ist, also in Richtung auf die Ausnehmung. Hierdurch kommt die der Kupplungsnase gegenüberliegende Kante des oberen Langlochs in Eingriff mit der Ausnehmung, so dass das Kuppelstück nicht vollständig entkuppelt. Der obere Container bleibt mit dem unteren Container verkuppelt. Das erfindungsgemäße Kuppelstück weist also gewisse Notlaufeigenschaften auf.The dome piece according to the invention is thus essentially like a fully automatic twistlock after DE 102 38 895 A1 or the corresponding WO 2004/020316 A1 educated. However, it is provided in the rear wall of the twistlock a groove-like recess, wherein the distance of a free edge of the coupling nose to the rear wall is less than or equal to the width of an upper slot in the upper corner fitting. As a result, there is no longer a "Z movement" when connecting and disconnecting. If the coupling nose slides on the tension side despite all precautions from the associated corner fitting, so get free behind the edge of the upper slot this corner fitting, the upper container slides horizontally on the lower container in a direction opposite to the direction in which the coupling nose is set, ie in the direction of the recess. As a result, the edge of the upper slot opposite the coupling nose engages with the recess, so that the coupling piece is not completely decoupled. The upper container remains coupled to the lower container. The coupling piece according to the invention thus has certain emergency running properties.

Durch die Ausnehmung entsteht auf der der Kupplungsnase abgewandten Seite eine weitere Nase. Diese Nase sollte eine schräg nach außen abfallende Schulter aufweisen. Hierdurch wird vermieden, dass sich der untere Kupplungsvorsprung am Langloch des Eckbeschlages verhakt, falls die Kante des Langlochs versehentlich während des Entladung des Containers in die Ausnehmung greifen sollte. Für diesen Zweck braucht die schräge Schulter nicht so flach zu sein wie eine schräge Schulter der Kupplungsnase. Der Winkel der Schulter zu einer Rückwand des unteren Kupplungsvorsprungs kann also größer sein als der Winkel der Schulter der Kupplungsnase zu einer Vorderwand. Aus fertigungstechnischen Gründen ist es besonders bevorzugt, wenn die Schulter der Nase mit einer Innenfläche einer Griffmulde im unteren Kupplungsvorsprung fluchtet. Die Kuppelstücke sind nämlich üblicherweise aus Stahlguss hergestellt und durch die fluchtende Schulter wird die Gussform vereinfacht.Through the recess is formed on the side facing away from the coupling nose another nose. This nose should have a sloping outward shoulder. This avoids that hooked the lower coupling projection on the slot of the corner fitting, if the edge of the slot should accidentally engage in the recess during the discharge of the container. For this purpose, the sloping shoulder need not be as flat as an oblique shoulder of the coupling nose. The angle of the shoulder to a rear wall of the lower coupling projection can therefore be greater than the angle of the shoulder of the coupling nose to a front wall. For manufacturing reasons, it is particularly preferred if the shoulder of the nose is aligned with an inner surface of a recessed grip in the lower coupling projection. The dome pieces are namely Usually made of cast steel and the aligned shoulder simplifies the mold.

Auf einer der Nase gegenüberliegenden Seite, also auf einer dem oberen Kupplungsvorsprung zugewandten Seite, ist die Ausnehmung nach einer Weiterbildung der Erfindung durch eine Einführschräge begrenzt. Sollte die Ausnehmung in der oben beschriebenen Weise zum Tragen kommen oder die Kante des Langlochs beim Verkuppeln des Kuppelstücks mit dem oberen Eckbeschlages unteren Containers versehentlich in die Ausnehmung gelangen (was aufgrund von Winddruck oder einem Pendeln des Containers am Kran vorkommen kann), wird durch die Einführschräge sichergestellt, dass das Kuppelstück (wieder) in seine gekuppelte Position gelangt.On a side opposite the nose, ie on a side facing the upper coupling projection side, the recess is bounded by a further development of the invention by an insertion bevel. Should the recess in the manner described above come to fruition or the edge of the slot when coupling the coupling piece with the upper corner fitting lower container inadvertently get into the recess (which may occur due to wind pressure or a pendulum of the container on the crane) is Insertion bevel ensures that the coupling piece (again) reaches its coupled position.

Die Erfindung wird nun anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben. In der Zeichnung zeigt:

Das gezeigte Kuppelstück weist einen oberen Kupplungsvorsprung 10 und einen unteren Kupplungsvorsprung 11 auf. Zwischen den Kupplungsvorsprüngen 10, 11 ist eine Anschlagplatte 12 angeordnet, welche gleichzeitig eine Trennebene zwischen zwei übereinander gestapelten Containern (nicht gezeigt) bildet. Die Unterseite der Anschlagplatte 12 liegt auf der Oberseite des oberen Eckbeschlages des unteren Containers auf, während die Unterseite des unteren Eckbeschlages des oberen Containers auf der Oberseite der Anschlagplatte 12 steht. Es ist aber erfindungsgemäß auch vorgesehen, die Anschlagplatte 12 in ansich bekannter Weise nur als keilartig vorstehenden Wulst auszubilden, der dann in einer aus Fasen an den Langlöchern der Eckbeschläge gebildete Nut eingreift, sodass die Eckbeschläge der Container direkt aufeinander stehen.The coupling piece shown has an upper coupling projection 10 and a lower coupling projection 11. Between the coupling projections 10, 11 a stop plate 12 is arranged, which simultaneously forms a parting plane between two stacked containers (not shown). The bottom of the stop plate 12 rests on the top of the upper corner fitting of the lower container, while the bottom of the lower corner fitting of the upper container is on the top of the stop plate 12. However, it is also provided according to the invention, form the stop plate 12 in a known manner only as a wedge-like projecting bead, which then engages in a groove formed on the slots of the Eckbeschläge groove, so that the corner fittings of the container are directly on each other.

Der obere Kupplungsvorsprung 10 weist oberhalb der Anschlagplatte 12 einen Schaft 13 auf, der wiederum an seiner der Anschlagplatte 12 abgewandten Seite einen Kopf 14 trägt. Wie in Fig. 1 gut zu erkennen ist, steht der Kopf 14 zu beiden Seiten über den Schaft 13 über, bildet also Verriegelungsvorsprünge 15 und 16.The upper coupling projection 10 has above the stop plate 12 on a shaft 13 which in turn on its side facing away from the stop plate 12 a Head 14 carries. As in Fig. 1 can be clearly seen, the head 14 is on both sides on the shaft 13, thus forming locking projections 15 and 16th

Der untere Kupplungsvorsprung 11 schließt ebenfalls mit einem Schaft 17 an die Anschlagplatte 12 an. Der Schaft 17 weist an einer Seite eine senkrecht zur Anschlagplatte 12 verlaufende Vorderwand 18 auf. An der der Vorderwand 18 gegenüberliegenden Seite weist der Schaft 17 eine Einführschräge 19 auf, die an ihrem der Anschlagplatte 12 zugewandten Ende in eine Fase 20 übergeht. Diese Fase 20 korrespondiert mit einer Fase am Langloch des Eckbeschlages und liegt bei eingekuppeltem Kuppelstück auf dieser Fase auf. Die Fase 20 könnte deshalb auch als Teil der Anschlagplatte 12 aufgefasst werden, insbesondere wenn die Anschlagplatte 12, wie oben dargelegt, nur als Wulst ausgebildet ist.The lower coupling projection 11 also includes a shaft 17 to the stop plate 12 at. The shaft 17 has on one side a perpendicular to the stop plate 12 extending front wall 18. At the front wall 18 opposite side of the shaft 17 has an insertion bevel 19, which merges at its end facing the stop plate 12 in a chamfer 20. This chamfer 20 corresponds to a chamfer on the slot of the corner fitting and rests with coupled coupling piece on this chamfer. The chamfer 20 could therefore also be regarded as part of the stop plate 12, in particular if the stop plate 12, as explained above, is formed only as a bead.

Die Einführschräge 19 geht an ihrem der Anschlagplatte 12 abgewandten Ende bogenartig in eine Rückwand 21 über, welche ebenfalls senkrecht zur Anschlagplatte 12 angeordnet ist.The insertion bevel 19 is at its end facing away from the stop plate 12 in an arc-like manner in a rear wall 21, which is also arranged perpendicular to the stop plate 12.

Der untere Kupplungsvorsprung 11 weist weiterhin einer Kupplungsnase 22 auf, welche der Rückwand 21 gegenüberliegt. Die Kupplungsnase 22 ist bezogen auf eine Längsachse der beiden miteinander zu verkuppelnden Container seitlich angeordnet. An ihrer Oberseite weist die Kupplungsnase 22 eine schräg nach außen abfallende Schulter 23 auf. Ferner ist an der Unterseite der Kupplungsnase 22 ein Einführkegel 24 angeordnet. Die Breite b der Kupplungsnase 22, also ein Abstand einer freien Kante 25 der Kupplungsnase 22 zur Rückwand 21, ist maximal genauso breit wie die Breite des Langlochs, in welches der untere Kupplungsvorsprung 11 eingreift.The lower coupling projection 11 further has a coupling nose 22, which is opposite to the rear wall 21. The coupling nose 22 is arranged laterally with respect to a longitudinal axis of the two containers to be coupled together. On its upper side, the coupling nose 22 has an obliquely outwardly sloping shoulder 23. Further, a Einführkegel 24 is disposed on the underside of the coupling nose 22. The width b of the coupling nose 22, that is, a distance of a free edge 25 of the coupling nose 22 to the rear wall 21, is at most as wide as the width of the slot into which the lower coupling projection 11 engages.

Insoweit entspricht zumindest der untere Kupplungsvorsprung 11 noch im Wesentlichen dem vollautomatischen Twistlock nach der DE 102 38 895 A1 . Im Gegensatz zu dem vollautomatischen Twistlock nach der DE 102 38 895 A1 weist das Kuppelstück nach dem vorliegenden Ausführungsbeispiel eine nutartige Ausnehmung 26 in der Rückwand 21 auf. Die Ausnehmung 26 erstreckt sich über die gesamte Länge des unteren Kupplungsvorsprungs 11 bzw. der Rückwand 21 und weist einen parallel zur Rückwand 21 verlaufenden Grund 27 auf. An ihrer dem oberen Kupplungsvorsprung 10 bzw. der Anschlagplatte 12 zugewandten Seite ist die Nut 26 durch eine Einführschräge 28 und an ihrer der Einführschräge 28 gegenüberliegenden, also vom oberen Kupplungsvorsprung 10 bzw. der Anschlagplatte 12 abgewandten Seite, durch eine schräge Schulter 29 begrenzt. Die Nut 26 hat also die Form eines Trapezes, wobei die Winkel der Einführschräge 28 einerseits und der schrägen Schulter 29 andererseits gegenüber der Rückwand 21 nicht gleich zu sein brauchen. Vielmehr ist in Fig. 1 gut zu erkennen, dass die Einführschräge 28 steiler ist, nämlich ein Winkel von etwa 135° aufweist, als die schräge Schulter 29, welche einen Winkel α29 von etwa 110° zur Rückwand 21 aufweist.In that regard, at least the lower coupling projection 11 still substantially corresponds to the fully automatic twistlock after DE 102 38 895 A1 , Unlike the fully automatic twistlock after the DE 102 38 895 A1 the coupling piece according to the present embodiment has a groove-like recess 26 in the rear wall 21. The recess 26 extends over the entire length of the lower coupling projection 11 and the rear wall 21 and has a parallel to the rear wall 21 extending bottom 27. At her the upper one Coupling projection 10 and the stop plate 12 facing side, the groove 26 by an insertion bevel 28 and at its the insertion chamfer 28 opposite, so from the upper coupling projection 10 and the stop plate 12 opposite side, bounded by an inclined shoulder 29. The groove 26 thus has the shape of a trapezoid, wherein the angle of the insertion bevel 28 on the one hand and the oblique shoulder 29 on the other hand need not be equal to the rear wall 21. Rather, it is in Fig. 1 good to see that the insertion bevel 28 is steeper, namely an angle of about 135 °, as the inclined shoulder 29, which has an angle α 29 of about 110 ° to the rear wall 21.

Weiterhin ist die schräge Schulter 29 nicht so steil, wie die schräge Schulter 23 der Kupplungsnase 22. Im vorliegenden Ausführungsbeispiel fluchtet die die Ausnehmung 26 begrenzende schräge Schulter 29 zu einer unteren Innenfläche 30 einer Griffmulde 31, welche in Fig. 1 als verdeckte Kante mit einer gestrichelten Linie dargestellt ist. Ganz allgemein kann gesagt werden, dass ein Winkel α23 der schrägen Schulter 23 der Kupplungsnase 22 zur Senkrechten, also zur Vorderwand 18, größer oder gleich dem Winkel α29 der die Ausnehmung 26 begrenzenden schrägen Schulter 29 zur Rückwand 21 ist.Furthermore, the oblique shoulder 29 is not as steep as the oblique shoulder 23 of the coupling nose 22. In the present embodiment, the recess 26 delimiting oblique shoulder 29 is aligned to a lower inner surface 30 of a recessed grip 31, which in Fig. 1 is shown as a hidden edge with a dashed line. In general, it can be said that an angle α 23 of the oblique shoulder 23 of the coupling nose 22 to the vertical, ie to the front wall 18, greater than or equal to the angle α 29 of the recess 26 bounding oblique shoulder 29 to the rear wall 21.

Durch die Ausnehmung 26 im unteren Kupplungsvorsprung 11 ist eine weitere Nase 32 gebildet, deren Oberseite die die Ausnehmung 26 begrenzende schräge Schulter 29 bildet. Mit dieser weiteren Nase 32 kann das Kuppelstück erforderlichenfalls hinter einer Kante am oberen Langloch des zugehörigen Eckbeschlages hacken.Through the recess 26 in the lower coupling projection 11, a further nose 32 is formed, the top of which forms the recess 26 bounding oblique shoulder 29. With this additional nose 32, the coupling piece can if necessary chop behind an edge on the upper slot of the associated corner fitting.

Die Verriegelungsvorsprünge 15, 16 des Kopfes 14 des oberen Kupplungsvorsprungs 10 weisen untere, der Anschlagplatte 12 zugewandte Auflageflächen 33 bzw. 34 auf. Die Auflagefläche 34 des Verriegelungsvorsprungs 16, der oberhalb der Verriegelungsnase 22 angeordnet ist, ist dabei dichter an der Oberseite der Anschlagplatte 12 (Trennebene zwischen den übereinander gestapelten Containern), also tiefer, angeordnet als die Auflagefläche 33 des gegenüberliegenden Verriegelungsvorsprungs 15.The locking projections 15, 16 of the head 14 of the upper coupling projection 10 have lower, the stop plate 12 facing bearing surfaces 33 and 34, respectively. The bearing surface 34 of the locking projection 16, which is arranged above the locking lug 22, is closer to the upper side of the stop plate 12 (parting plane between the stacked containers), ie lower, arranged as the bearing surface 33 of the opposite locking projection 15th
