The locking device has at least two locking elements (13) which lock the door to the housing on the side on which it is hinged to the housing and on the opposite side. An Independent claim is also included for a container, especially an insulating container, comprising the above locking arrangement.

Description

Die Erfindung betrifft einen Behälter, insbesondere Isolierbehälter, mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a container, in particular insulated container, having the features of the preamble of patent claim 1.

Isolierbehälter werden beispielsweise verwendet, um Kühl- oder Gefriergut aus großen Kühlhäusern in Einzelhandelsgeschäfte zu transportieren, in denen das Gut in Kühltruhen bzw. Gefriertruhen bis zum Verkauf an den Endverbraucher weiter gelagert wird. Derartige Isolierbehälter können beispielsweise eine Höhe von 2 Meter, eine Breite von ca. 70 cm und eine Tiefe von ca. 80 cm aufweisen. Am Boden angeordnete Rollen oder Kufen ermöglichen den einfachen Transport der Behälter.Insulating containers are used, for example, to transport refrigerated or frozen goods from large cold stores to retail outlets in which the goods are stored in freezers or freezers until they are sold to the end user. Such insulating containers may for example have a height of 2 meters, a width of about 70 cm and a depth of about 80 cm. On the floor arranged rollers or runners allow easy transport of the container.

Ein bekannter Behälter weist ein Gehäuse auf, welches fast in vollem Umfang aus Kunststoff gefertigt ist. Das Gehäuse besteht aus einer doppelwandigen Kunststoffhaut, die beispielsweise im Rotationsverfahren hergestellt wird, wobei der Zwischenraum mit einem PUR-Material ausgeschäumt wird. In gleicher Weise wird die Türe eines derartigen Behälters hergestellt. In der Türe des Behälters ist eine Verriegelungsvorrichtung vorgesehen, die die Türe an der den Scharnieren gegenüberliegenden Seite oben und unten mit dem Behälter verriegelt. Die Scharniere bzw. Gelenke der Türe sind üblicherweise ebenfalls im unteren und oberen Bereich der Türe (in der Höhe des Behälters gesehen) angeordnet.A known container has a housing which is made almost entirely of plastic. The housing consists of a double-walled plastic skin, which is produced for example by rotation, wherein the gap is foamed with a PUR material. In the same way, the door of such a container is made. In the door of the container, a locking device is provided, which locks the door on the side opposite the hinges up and down with the container. The hinges or joints of the door are usually also in the lower and upper part of the door (seen in the height of the container) arranged.

Als problematisch bei derartigen Behältern erweist sich, dass in Folge der thermischen Eigenschaften des Kunststoffmaterials das Material relativ weich oder elastisch wird, wenn die Umgebungstemperatur entsprechend hoch ist. Da auch die Transportgriffe zum Ziehen oder Schieben des Behälters in etwa in der Mitte des Behälters an den Seiten oder auch der Türe des Behälters vorgesehen sind, kommt es in Folge der zusätzlichen mechanischen Kräfte zu einer Ausbauchung der Behälterwandungen oder der Türe, wodurch der Behälter undicht werden kann. Bei derart deformierten Behältern reduziert sich die Zeit, während der der Behälter gewährleistet, dass das darin befindliche Gut eine vorgegebene Temperatur nicht überschreitet, auf einen unzulässig niedrigen Wert. Dies führt dazu, dass derartige Behälter repariert oder gar vollständig ausgetauscht werden müssen.A problem with such containers proves that due to the thermal properties of the plastic material, the material is relatively soft or elastic, when the ambient temperature is correspondingly high. Since the transport handles for pulling or pushing the container are provided approximately in the middle of the container on the sides or the door of the container, it comes as a result of additional mechanical forces to a bulge of the container walls or the door, causing the container leaking can be. With such deformed containers, the time during which the container ensures that the material therein does not exceed a predetermined temperature, reduced to an impermissibly low value. As a result, such containers must be repaired or even completely replaced.

Auch bei bekannten Behältern, die an den Außenkanten durch Metallwinkel verstärkt sind oder gar komplette Außenwandungen aus einem Metallblech aufweisen, existiert die vorstehend beschriebene Gefahr des Undichtwerdens, denn auch diese Behälter weisen im Regelfall lediglich zwei Scharniere auf, von denen jeweils eines im oberen bzw. unteren Bereich der Türe angeordnet ist, und eine Verriegelungsvorrichtung, welche die Türe an der gegenüberliegenden Seite in etwa in der Mitte der Behälterhöhe mit dem Gehäuse verriegelt.Even with known containers that are reinforced at the outer edges by metal angle or even have complete outer walls of a metal sheet, there is the above-described risk of leakage, because even these containers generally have only two hinges, one of which in the upper or The lower portion of the door is arranged, and a locking device which locks the door on the opposite side approximately at the center of the container height with the housing.

Aus der JP 2001-208464 A ist ein Kühlbehälter gemäß dem Oberbegriff des Anspruchs 1 bekannt, bei dem die Türe an der den Scharnieren gegenüberliegenden Seite durch jeweils ein Verriegelungselement an der oberen und unteren Seite der Türe mit dem Behälter verriegelbar ist.From the JP 2001-208464 A a cooling container according to the preamble of claim 1 is known, wherein the door on the opposite side of the hinge by a respective locking element on the upper and lower side of the door with the container is lockable.

Aus der EP 0 738 814 A1 ist eine Vorrichtung an einem Türschloss bekannt, bei der mittels eines Betätigungsmechanismus, der beispielsweise von einem Schlüsselzylinder angetrieben sein kann, mehrere Schließbolzen in eine Verriegelungsstellung gebracht werden können. Diese Verriegelungsbolzen können an der Oberseite und der Unterseite der Türe, an der Seite der Türe, die nicht am Türstock angelenkt ist, vorgesehen sein sowie in einem linken und rechten Bereich in etwa der Mitte der Türe. Der Betätigungsmechanismus ist als Zahnradgetriebe ausgebildet. Der gesamte Offenbarungsgehalt dieser Veröffentlichung ist auf die speziellen Bedürfnisse des sicheren Verschließens von Haus- oder Gebäudetüren gerichtet. Zum Öffnen der Türe muss zunächst die Verriegelung durch das Drehen des Schlüssels im Schlosszylinder mittels des betreffenden Betätigungsmechanismus gelöst werden. Erst anschließend kann die Türe durch Drücken der Klinge geöffnet werden.From the EP 0 738 814 A1 a device on a door lock is known in which by means of an actuating mechanism, which may be driven by a key cylinder, for example, a plurality of locking pins can be brought into a locking position. These locking bolts can be provided on the top and bottom of the door, on the side of the door which is not hinged to the door frame, and in a left and right area approximately in the middle of the door. The actuating mechanism is designed as a gear transmission. The entire disclosure of this publication is directed to the specific needs of the secure closure of house or building doors. To open the door, the lock must first be solved by turning the key in the lock cylinder by means of the relevant operating mechanism. Only then can the door be opened by pressing the blade.

Als weiteres Problem bei bekannten Behältern erweist sich, dass die Behälter an der Frontseite nach Möglichkeit keinerlei Elemente aufweisen dürfen, die über die Vorderfront der Türe hinausragen. Hierdurch kann gewährleistet werden, dass die Behälter dicht an dicht gestellte werden können, ohne dass sich die Behälter gegenseitig beschädigen, beispielsweise während Transporten auf einem LKW. Aus diesem Grund ist das Betätigungselement der Verriegelungsvorrichtung in einer Ausnehmung in der Dicke der Türe aufgenommen. Die Ausnehmung muss eine solche Größe aufweisen, dass das Betätigungselement über den gesamten erforderlichen Bewegungsbereich innerhalb der Ausnehmung bewegt werden kann. Eine derartige Ausnehmung bewirkt jedoch eine geringere Wanddicke, wodurch die mechanische Stabilität ebenfalls beeinträchtigt wird. Zudem ist in diesem Bereich der Ausnehmung der Wärmedurchgangswiderstand vom Behälterinneren in Richtung der Behälteraußenseite deutlich reduziert. Im Bereich der Ausnehmung treten daher deutlich höhere Wärmeverluste auf, als an den übrigen Bereichen der Behälterwandungen, in denen diese wesentlich dicker ausgebildet sein kann.Another problem with known containers proves that the container on the front should not, if possible, have any elements that protrude beyond the front of the door. In this way it can be ensured that the containers can be placed close to each other without the containers being mutually damaged, for example during transport on a truck. For this reason, the actuating element of the locking device is received in a recess in the thickness of the door. The recess must have a size such that the actuating element on the Whole required range of motion can be moved within the recess. However, such a recess causes a smaller wall thickness, whereby the mechanical stability is also impaired. In addition, in this region of the recess, the heat transfer resistance from the container interior in the direction of the container outside is significantly reduced. In the region of the recess, therefore, significantly higher heat losses occur than at the remaining areas of the container walls, in which these can be made substantially thicker.

Ausgehend von dem eingangs genannten Stand der Technik liegt der Erfindung die Aufgabe zu Grunde, einen Behälter, insbesondere Isolierbehälter zu schaffen, welcher eine möglichst hohe mechanische Stabilität aufweist und trotz hoher mechanischer Belastungen des Gehäuses bzw. der Türe über die gesamte Lebensdauer die geforderte isolierende Wirkung gewährleistet.Based on the above-mentioned prior art, the invention is based on the object to provide a container, in particular insulating container, which has the highest possible mechanical stability and despite high mechanical loads on the housing or the door over the entire life of the required insulating effect guaranteed.

Die Erfindung löst diese Aufgabe mit den Merkmalen des Patentanspruchs 1.The invention solves this problem with the features of patent claim 1.

Die Verriegelungsvorrichtung des erfindungsgemäßen Behälters gewährleistet eine mechanische Verriegelung der Türe nicht nur an der der Scharnierseite gegenüberliegenden Seite, sondern auch an der Scharnierseite selbst. Hierdurch ergibt sich der Vorteil, dass durch Materialerweichungen in Folge thermischer Belastungen des Behälters und/oder mechanischer Krafteinwirkungen auf den Behälter bzw. die Türe selbst keine derart gravierende Deformation, insbesondere Bombage, der Türe auftreten kann, die schließlich dazu führt, dass der Behälter undicht wird und seine isolierenden Eigenschaften beeinträchtigt werden. Die Verriegelungsvorrichtung umfasst hierzu wenigstens zwei Verriegelungselemente, mit welchen die Türe an der Scharnierseite und der gegenüberliegenden Seite mit dem Gehäuse verriegelt wird.The locking device of the container according to the invention ensures a mechanical locking of the door not only on the hinge side opposite side, but also on the hinge side itself. This results in the advantage that material softening as a result of thermal stress on the container and / or mechanical force on the container or the door itself no such serious deformation, in particular camber, the door can occur, which eventually leads to the container is leaking and its insulating properties are impaired. For this purpose, the locking device comprises at least two locking elements with which the door is locked to the housing on the hinge side and the opposite side.

Nach der Erfindung ist die Türe im oberen und unteren Bereich am Gehäuse angelenkt und das betreffenden Verriegelungselement verriegelt die Türe auch an der Anlenkungsseite im Bereich zwischen den Anlenkungen, vorzugsweise im Wesentlichen mittig zwischen den Anlenkungen, mit dem Gehäuse.According to the invention, the door is articulated in the upper and lower portions of the housing and the respective locking element locks the door also on the linkage side in the region between the linkages, preferably substantially centrally between the linkages, with the housing.

Erfindungsgemäß ist für das Antreiben der wenigstens zwei Verriegelungselemente eine drehbare Achse vorgesehen, die sich bis in die Bereich der mit dem Gehäuse verriegelbaren, gegenüberliegenden Seiten der Türe erstreckt. Mit der drehbaren Achse ist, vorzugsweise gelenkig, ein Hebel verbunden, der zur Rotation der Achse und damit zum Antreiben der wenigstens zwei Verriegelungselemente dient.According to the invention, a rotatable axle is provided for driving the at least two locking elements, which extends into the region of the opposite sides of the door which can be locked with the housing. With the rotatable axis, preferably a lever, a lever is connected, which serves to rotate the axis and thus to drive the at least two locking elements.

Der gelenkig mit der Achse verbundene Hebel liegt in seiner Ruhelage vorzugsweise im Wesentlichen parallel zur drehbaren Achse. Zum Betätigen der Verriegelungsvorrichtung wird der Hebel in eine Stellung geschwenkt, in der sich ein ausreichender Hebelarm für das Rotieren der Achse ergibt.The lever pivotally connected to the axis is in its rest position preferably substantially parallel to the rotatable axis. To actuate the locking device, the lever is pivoted to a position in which there is a sufficient lever arm for rotating the axle.

Vorzugsweise ist das Betätigungselement bzw. der Hebel zumindest in der verriegelten Stellung in einer Ausnehmung in der Oberseite bzw. Außenseite der Türe aufgenommen und ragt dabei nicht oder allenfalls geringfügig über die Oberfläche der Türe hinaus. Hierdurch wird gewährleistet, dass die Behälter zum Transport dicht an dicht gestellt werden können, ohne dass durch über die Oberfläche der betreffenden Seite hinausragende Elemente der jeweils anliegende Behälter beschädigt wird.Preferably, the actuating element or the lever is received at least in the locked position in a recess in the top or outside of the door and protrudes not or at most slightly beyond the surface of the door. This ensures that the containers can be placed tightly packed for transport, without damaging over the surface of the relevant side protruding elements of the respective adjacent container.

In einer weiteren Ausführungsform der Erfindung sind die wenigstens zwei Verriegelungselemente drehfest mit der drehbaren Achse verbunden und wirken mit im Gehäuse angeordneten komplementären Verriegelungselementen zur Verriegelung und Entriegelung der Tür zusammen, wenn eine entsprechende Drehung der Achse erfolgt. Die Verriegelungselemente können dabei einen an der Achse drehfest befestigten Arm aufweisen, der für das Verriegeln einen im Gehäuse angeordneten Bolzen hintergreift.In a further embodiment of the invention, the at least two locking elements are non-rotatably connected to the rotatable shaft and cooperate with arranged in the housing complementary locking elements for locking and unlocking the door when a corresponding rotation of the axis takes place. The locking elements can have a non-rotatably mounted on the axis arm, which engages behind a bolt arranged in the housing for locking.

Nach der Erfindung kann mittels der drehbaren Achse oder mittels einem der drehbar ausgebildeten Verriegelungselemente wenigstens ein weiteres Verriegelungselement angetrieben werden, welches die Türe an der nicht-angelenkten Seite, vorzugsweise im oberen oder unteren Bereich, mit dem Gehäuse verriegelt.According to the invention, at least one further locking element can be driven by means of the rotatable axle or by means of one of the rotatably formed locking elements, which locks the door on the non-hinged side, preferably in the upper or lower area, with the housing.

Nach einer Ausführungsform kann zusätzlich zur Verriegelung der Türe an der Anlenkungsseite eine Verriegelung der Türe an der nicht-angelenkten Seite im oberen und unteren Bereich und in einem Bereich dazwischen erfolgen.
Zusammen mit den vorzugsweise zwei Anlenkungen ergeben sich somit im verriegelten Zustand insgesamt mindestens sechs Fixierpunkte in denen die Türe mit dem Gehäuse verbunden ist.According to one embodiment, in addition to the locking of the door on the articulation side, a locking of the door to the non-hinged Side in the upper and lower areas and in an area in between.
Together with the preferably two linkages thus result in the locked state a total of at least six fixing points in which the door is connected to the housing.

Das wenigstens eine weitere Verriegelungselement ist als Schubstange ausgebildet, welche exzentrisch, vorzugsweise gelenkig, mit der drehbaren Achse oder vorzugsweise mit einem der drehbar ausgebildeten Verriegelungselemente verbunden ist. Die Schubstange erstreckt sich dabei vorzugsweise in einer Richtung senkrecht zur drehbaren Achse. Auf diese Weise kann der Behälter zusätzlich zu einer Verriegelung an der Scharnierseite und der gegenüberliegenden Seite an der Ober- und/oder Unterseite mit dem Gehäuse verriegelt werden.The at least one further locking element is designed as a push rod, which is eccentrically, preferably articulated, connected to the rotatable axle or preferably to one of the rotatably formed locking elements. The push rod preferably extends in a direction perpendicular to the rotatable axis. In this way, the container can be locked to the housing in addition to a lock on the hinge side and the opposite side on the top and / or bottom.

Werden die eine oder mehreren Schubstangen mit den drehfest mit der drehbaren Achse verbundenen Verriegelungselementen gekoppelt, so erfolgt das Verriegeln der Tür an deren Ober- und/oder Unterseite in einem der der Scharnierseite gegenüberliegenden Bereich der Türe und/oder im Bereich der Scharnierseite selbst.If the one or more push rods coupled to the rotatably connected to the rotatable shaft locking elements, the locking of the door at the top and / or bottom takes place in one of the hinge side opposite region of the door and / or in the hinge side itself.

Selbstverständlich können mittels der drehbaren Achse auch eine oder mehrere Schubstangen mittels eines separaten Exzenterelements angetrieben werden, welches an einer anderen Stelle der drehbaren Achse, beispielsweise in der Mitte der Tür angeordnet ist. Durch das Verriegeln der Türe mit dem Gehäuse in der Mitte der Türe (in Richtung der Türbreite gesehen; Verriegelung an der Ober- und/oder Unterseite) wird auch eine Bombage der Türe in dieser Richtung reduziert bzw. verhindert.Of course, one or more push rods can be driven by means of a separate eccentric element by means of the rotatable shaft, which is arranged at a different location of the rotatable shaft, for example in the middle of the door. By locking the door with the housing in the middle of the door (seen in the direction of the door width, locking at the top and / or bottom) and a camber of the door in this direction is reduced or prevented.

Das Verriegeln der Türe mittels der einen oder mehreren Schubstangen kann in der Weise erfolgen, dass die betreffende Schubstange an ihrem freien Ende im verriegelten Zustand über die betreffende Außenkante der Türe hinausragt und in ein im oder am Gehäuse angeordnetes Aufnahmeelement oder einen im oder am Gehäuse ausgebildeten Aufnahmebereich (weiteres komplementäres Verriegelungselement) eingreift.The locking of the door by means of the one or more push rods can be done in such a way that the relevant push rod protrudes at its free end in the locked state over the respective outer edge of the door and in a housing arranged in or on the receiving element or in or on the housing Receiving area (further complementary locking element) engages.

Nach der bevorzugten Ausführungsform der Erfindung ist eine Blockiervorrichtung vorgesehen, welche bei entriegelter und geöffneter Türe das Betätigen der Verriegelungsvorrichtung zu deren Überführung in den verriegelten Zustand blockiert. Hierdurch wird vermieden, dass bei einem Schließen des Behälters mit bereits in der verriegelten Position befindlichen Elementen der Behälter beschädigt wird.According to the preferred embodiment of the invention, a blocking device is provided which, when the door is unlocked and opened, actuates the locking device blocked for their transfer to the locked state. This avoids that when closing the container with already in the locked position elements of the container is damaged.

Nach einer Ausführungsform der Erfindung kann die Blockiervorrichtung ein federbeaufschlagtes Blockierelement umfassen, welches nach dem Überführen der wenigstens zwei Verriegelungselemente in den entriegelten Zustand und nach dem Öffnen der Türe selbsttätig in eine die Bewegung des Betätigungselements oder der wenigstens zwei Verriegelungselemente blockierende Stellung gebracht wird.According to one embodiment of the invention, the blocking device may comprise a spring-loaded blocking element, which is brought into a blocking the movement of the actuating element or the at least two locking elements automatically after transferring the at least two locking elements in the unlocked state and after opening the door.

Das Blockierelement kann dabei als ein einfacher Schieber ausgebildet sein, welcher in der blockierenden Stellung die Bewegung des freien Endes der Schubstange blockiert.The blocking element can be designed as a simple slide, which blocks the movement of the free end of the push rod in the blocking position.

Um ein ansonsten erforderliches manuelles Freigeben der Verriegelungsvorrichtung zu vermeiden, kann die Blockiervorrichtung ein am Gehäuse vorgesehenes Freigabeelement umfassen, welche mit dem Blockierelement derart zusammenwirkt, dass das Blockierelement in eine nicht-blockierende Stellung überführt wird, sobald die Türe über einen vorgegebenen minimalen Öffnungswinkel hinaus geschlossen wird.In order to avoid otherwise required manual release of the locking device, the blocking device may comprise a housing provided on the release element which cooperates with the blocking element such that the blocking element is transferred to a non-blocking position as soon as the door closed over a predetermined minimum opening angle becomes.

Beispielsweise kann das Blockierelement oder ein damit verbundenes Betätigungselement einen Führungsanschlag aufweisen, welcher mit einer die Freigabebewegung des Blockierelements bewirkenden Führungsfläche des Freigabeelements zusammenwirkt. Die Freigabefläche kann auch unmittelbar an einem Aufnahmeelement bzw. einem komplementären Verriegelungselement vorgesehen sein, mit dem eines der Verriegelungselement, beispielsweise eine Schubstange zusammenwirkt. Das Aufnahmeelement dient in diesem Fall gleichzeitig als Freigabeelement.For example, the blocking element or an actuating element connected thereto may have a guide stop, which cooperates with a guide surface of the release element which effects the release movement of the blocking element. The release surface may also be provided directly on a receiving element or a complementary locking element, with which one of the locking element, for example a push rod cooperates. The receiving element serves in this case simultaneously as a release element.

Die Blockiervorrichtung gewährleistet, dass ein Betätigen der Verriegelungsvorrichtung nur dann möglich ist, wenn die Türe schon weitgehend geschlossen ist bzw. sich in einer Stellung befindet, in der durch das Betätigen der Verriegelungsvorrichtung keine Beschädigung des Behälters mehr möglich ist.The locking device ensures that actuation of the locking device is only possible when the door is already largely closed or is in a position in which no damage to the container is possible by operating the locking device.

Weitere Ausführungsformen der Erfindung ergeben sich aus den Unteransprüchen.Further embodiments of the invention will become apparent from the dependent claims.

Die Erfindung wird nachfolgend an Hand eines in der Zeichnung dargestellten Ausführungbeispiels näher erläutert. In der Zeichnung zeigen

a schematic perspective view of a container with a locking device according to an embodiment of the invention;

Der in Fig. 1 perspektivisch und schematisch dargestellte Behälter 1, bei dem es sich im Speziellen um einen Isolierbehälter handeln kann, umfasst ein Gehäuse 3, welches mittels einer Türe 5 verschließbar ist. Die Türe ist über Gelenkelemente 7 am Gehäuse angelenkt. Die Gelenkelemente 7 sind dabei einerseits gelenkig mit der Türe und andererseits gelenkig mit dem Gehäuse 3 verbunden und definieren Drehachse A, A'. Diese Art und Weise der Anlenkung der Türe ermöglicht ein Öffnen der Türe bis zu einem Winkel von 270°, d. h. dass die Türe im maximal verschwenkten Zustand an der betreffenden benachbarten Längsseite des Behälters 3 anliegen kann.The in Fig. 1 Perspective and schematically represented container 1, which may in particular be an insulating container, comprises a housing 3, which is closable by means of a door 5. The door is articulated via hinge elements 7 on the housing. The joint elements 7 are on the one hand hinged to the door and on the other hand articulated to the housing 3 and define axis of rotation A, A '. This way of articulation of the door allows the door to open up to an angle of 270 °, ie that the door can rest against the relevant adjacent longitudinal side of the container 3 in the maximum pivoted state.

In der Türe und in benachbarten Bereichen des Behälters ist eine Verriegelungsvorrichtung 9 vorgesehen, mittels welcher die Türe fest mit dem Behälter verriegelbar ist. Die Verriegelungsvorrichtung 9 umfasst in dem in Fig. 1 dargestellten Ausführungsbeispiel eine drehbare Achse 11, die im Wesentlich horizontal in der Türe 5 gelagert ist. In den äußeren Seitenbereichen der Türe sind Verriegelungselemente 13 vorgesehen, die drehfest mit der Achse 11 verbunden sind. Die Verriegelungselemente 13 umfassen Arme, welche im verriegelten Zustand in den Seitenwandungen der Gehäuse vorgesehene komplementäre Verriegelungselemente hintergreifen. Diese Situation ist in Fig. 2 schematisch dargestellt. Diese teilweise aufgebrochene Seitenansicht zeigt die Verriegelungselemente 13 in der verriegelten Position, in der die Arme 15 die komplementären Verriegelungselemente 17 hintergreifen. Die komplementären Verriegelungselemente können dabei als einfache, in den Seitenwandungen des Gehäuses im Wesentlichen horizontal verlaufende Bolzen oder Lagerbuchsen ausgebildet sein. Selbstverständlich sind in den Seitenwandungen entsprechende Taschen oder Ausnehmungen vorgesehen, in welche jeweils der Arm 15 des betreffenden Verriegelungselements 13 eingreifen kann, so dass nach dem vollständigen Verschwenken der Verriegelungselemente 13 in die verriegelte Position das Öffnen der Türe 5 blockiert ist. Die mit dem Bolzen zusammenwirkende Ausnehmung des Arms 15 kann so ausgeführt sein, dass sich eine Selbsthemmung ergibt.In the door and in adjacent areas of the container, a locking device 9 is provided, by means of which the door is firmly locked to the container. The locking device 9 comprises in the in Fig. 1 illustrated embodiment, a rotatable shaft 11 which is mounted substantially horizontally in the door 5. In the outer side regions of the door locking elements 13 are provided, which are rotatably connected to the axis 11. The locking elements 13 comprise arms which engage in the locked state in the side walls of the housing provided complementary locking elements. This situation is in Fig. 2 shown schematically. This partially broken side view shows the locking elements 13 in the locked position, in which the arms 15 engage behind the complementary locking elements 17. The complementary locking elements can be designed as a simple, in the side walls of the housing substantially horizontally extending bolts or bearing bushes. Of course, corresponding pockets or recesses are provided in the side walls, in each of which the arm 15 of the respective locking element 13 can engage, so that after the complete pivoting of the locking elements 13 in the locked position, the opening of the door 5 is blocked. The cooperating with the bolt recess of the arm 15 may be designed so that there is a self-locking.

Für das Rotieren der Achse 11 ist an der Achse ein Betätigungselement 12 vorgesehen, welches gelenkig mit der Achse verbunden ist. Wie in Fig. 1 dargestellt, kann an der Achse 11 ein kurzer Arm 11 a vorgesehen sein, an welchem das Betätigungselement 12 angelenkt ist. Die Schwenkachse des Betätigungselements 12 kann in der verriegelten Stellung beispielsweise in einem Winkel von 45° zur Ebene der Türoberfläche und senkrecht zur Achse 11 verlaufen. Das Betätigungselement 12 liegt in seiner Ruhestellung im Wesentlichen parallel zur Achse 11. Durch die Ausnehmung 14 in der Frontseite der Türe 5 kann sichergestellt werden, dass das Betätigungselement 12 in seiner Ruhelage nicht über die Oberfläche der Türe 5 hinausragt. Dadurch können die Behälter ohne die Gefahr der Beschädigung dicht an dicht gestellt werden. Für das Betätigen der Verriegelungsvorrichtung wird das Betätigungselement 12 soweit aus seiner Ruhelage herausgeschwenkt, bis ein ausreichender Hebelarm zur Drehung der Achse 11 vorliegt. Nach erfolgter Drehung kann das Betätigungselement 12 wieder in seine zur Achse 1 parallele Lage zurückgeschwenkt werden. Da die Drehbewegung der Achse 11 bei herausgeschwenktem Betätigungselement 12 erfolgt, kann die Ausnehmung 14 hinsichtlich ihres Flächenbedarfs sehr klein ausgeführt werden. Hierdurch ergibt sich der Vorteil einer nur geringen Fläche der Türe, in der ein reduzierter Wärmedurchgangswiderstand gegeben ist und in der die mechanische Stabilität geringer ist, als in den übrigen Bereichen der Türe, wenn nicht zusätzliche (meist aufwändige) Maßnahmen ergriffen werden.For the rotation of the axle 11, an actuating element 12 is provided on the axle, which is pivotally connected to the axle. As in Fig. 1 shown, may be provided on the axis 11, a short arm 11 a, on which the actuating element 12 is articulated. The pivot axis of the actuating element 12 may extend in the locked position, for example, at an angle of 45 ° to the plane of the door surface and perpendicular to the axis 11. The actuator 12 is in its rest position substantially parallel to the axis 11. By the recess 14 in the front of the door 5 can be ensured that the actuator 12 does not protrude in its rest position on the surface of the door 5. This will allow the containers to be sealed tight without the risk of damage. For operating the Locking device, the actuating element 12 is pivoted out of its rest position until a sufficient lever arm for rotation of the axis 11 is present. After rotation, the actuator 12 can be swung back into its parallel to the axis 1 position. Since the rotational movement of the axle 11 takes place when the actuating element 12 is pivoted out, the recess 14 can be made very small in terms of its area required. This results in the advantage of only a small surface of the door, in which a reduced heat transfer resistance is given and in which the mechanical stability is lower than in the other areas of the door, if not additional (usually expensive) measures are taken.

Das Betätigungselement 12 kann auch mittels eines federnden Elements (nicht dargestellt) in Richtung auf seine Ausgangslage beaufschlagt sein, so dass es nach einem Herausschwenken aus seiner Ausgangslage selbsttätig in diese zurückgeführt wird, wenn die Bedienperson das Betätigungselement loslässt.The actuating element 12 can also be acted upon by means of a resilient element (not shown) in the direction of its initial position, so that it is automatically returned to its swing out from its initial position in this, when the operator releases the actuator.

Um das Betätigungselement in seiner Ausgangslage (parallel zur Achse 11) in der verriegelten Stellung und in der entriegelten Stellung der Verriegelungsvorrichtung zu fixieren, kann in der Ausnehmung 14 ortsfest ein Fixierelement 16 angeordnet sein. Das Fixierelement 16 ist so ausgebildet, dass es vom Betätigungselement 12 sowohl in der verriegelten Stellung als auch der entriegelten Stellung der Verriegelungsvorrichtung hintergriffen wird, wenn sich das Betätigungselement in seiner Ausgangslage befindet (in des es vorzugsweise durch das federnde Element gehalten ist). Dazu kann das Fixierelement 16 im Wesentlichen dreieckförmig ausgebildet sein, wobei das dreieckförmige Element mit seiner Spitze in der Ausnehmung 14 fest angeordnet ist. Die Anlageflächen des bzw. -kanten des Fixierelements können leicht nach innen gekrümmt sein, um das Betätigungselement sicher zu fixieren. Das Betätigungselement 12muss zum Öffnen soweit herausgeschwenkt werden, bis es gegenüber dem Fixierelement 16 frei liegt und eine Drehung der Achse 11 möglich ist. In der entriegelten Stellung kann das Betätigungselement dann wieder aktiv und/oder infolge der Federbeaufschlagung einwärts geschwenkt werden. Die Drehung der Achse 11 muss dabei um einen solchen Winkel erfolgen, dass in der erreichten Winkelstellung ein vollständiges Einwärtsschwenken des Betätigungselements 12 möglich ist. In Zwischenstellungen würde das Betätigungselement mit seiner inneren Wandung an der vorderen Stirnseite des Fixierelements anliegen, so dass dieses nicht in seine Ausgangslage gebracht werden kann. Dies zeigt einer Bedienperson sofort, dass die entriegelte bzw. verriegelte Position der Verriegelungsvorrichtung nicht korrekt erreicht wurde und eine Korrektur erforderlich ist.In order to fix the actuating element in its initial position (parallel to the axis 11) in the locked position and in the unlocked position of the locking device, a fixing element 16 can be arranged in the recess 14 in a stationary manner. The fixing element 16 is designed such that it is engaged behind by the actuating element 12 in both the locked position and the unlocked position of the locking device when the actuating element is in its initial position (in which it is preferably held by the resilient element). For this purpose, the fixing member 16 may be formed substantially triangular, wherein the triangular-shaped element is fixedly arranged with its tip in the recess 14. The abutment surfaces of the or-edges of the fixing element can be slightly curved inwards to securely fix the actuating element. The actuating element 12 must be swung out to open so far, until it is exposed to the fixing member 16 and a rotation of the shaft 11 is possible. In the unlocked position, the actuating element can then be active again and / or inwardly as a result of the spring loading be panned. The rotation of the axle 11 must be made at such an angle that in the achieved angular position, a complete inward pivoting of the actuating element 12 is possible. In intermediate positions, the actuating element would abut with its inner wall on the front end side of the fixing element, so that this can not be brought into its initial position. This immediately indicates to an operator that the unlocked position of the locking device has not been reached correctly and a correction is required.

Durch das Verriegeln der Türe mittels der beiden Verriegelungselemente 13 an beiden gegenüberliegenden Seiten in den Seitenwandungen des Gehäuses 3 ist gewährleistet, dass bei mechanischen Belastungen der Türe ein Deformieren der Türe vermieden wird. Beispielsweise ist es üblich, an einem derartigen Isolierbehälter einen oder mehrere Griffe 19a, 19b vorzusehen, um den Behälter zu transportieren, beispielsweise auf Rollen 21 zu ziehen, oder anzuheben. Die Griffe 19a, 19b sind ebenfalls so ausgeführt, dass sie nicht über die Außenkontur bzw. die Außenwandungen des Gehäuses 3 bzw. der Türe 5 hinausragen, um ein dicht an dich Stellen mehrerer Behälter 1 zu ermöglichen.By locking the door by means of the two locking elements 13 on both opposite sides in the side walls of the housing 3 ensures that under mechanical loads on the door, a deformation of the door is avoided. For example, it is customary to provide one or more handles 19a, 19b on such an insulated container in order to transport the container, for example to pull on rollers 21, or to raise it. The handles 19 a, 19 b are also designed so that they do not protrude beyond the outer contour or the outer walls of the housing 3 and the door 5, to allow a close to you places several containers 1.

Bei bekannten Behältern, die eine Verriegelungsvorrichtung mit in der Türe vorgesehenen Schubstangen aufweisen, um die Türe im oberen und unteren Bereich zu verriegeln, war es problematisch, die für die an den vorderen Kanten der Türe 5 vorgesehenen Griffe 19b erforderlichen Griffmulden ausreichend groß auszuführen. Denn die Schubstangen mussten im Bereich dieser Griffmulden in der verbleibenden Türwandung mit geringerer Dicke geführt werden. Die Dicke der Türwandung in diesen Bereichen musste daher relativ groß gewählt werden, wodurch die Tiefe der Ausnehmung begrenzt war. Für Bedienpersonen war es daher insbesondere bei Verwendung von Arbeitshandschuhen oftmals unbequem oder sogar unmöglich, die Hand in die Griffmulde einzuführen.In known containers, which have a locking device provided with push rods in the door to lock the door in the upper and lower areas, it was problematic to make necessary for the provided at the front edges of the door handles 17 19 recessed grips sufficiently large. Because the push rods had to be performed in the area of these recessed grips in the remaining wall of the door with a smaller thickness. The thickness of the door wall in these areas had therefore to be chosen to be relatively large, whereby the depth of the recess was limited. For operators, it was therefore often inconvenient or even impossible to insert the hand into the recessed grip, especially when using work gloves.

Aus diesem Grund wird bei der in Fig. 1 dargestellten Ausführungsform die Schubstange 23 zur Verriegelung der Türe 5 im oberen Bereich durch ein Rohr 24 geführt, welches den Griff 19b bildet. Durch diese Maßnahme kann die Griffmulde mit der erforderlichen Tiefe ausgebildet werden.For this reason, at the in Fig. 1 illustrated embodiment, the push rod 23 is guided to lock the door 5 in the upper part by a tube 24, which forms the handle 19b. By this measure, the recessed grip can be formed with the required depth.

Zusätzlich zur Verriegelung der Türe mit den vertikalen Seitenwänden des Gehäuses 3 kann eine Verriegelung der Türe mit den horizontalen Wänden (Boden und Deckel) des Gehäuses 3 bzw. im oberen und unteren Bereich der Türe erfolgen. Wie in Fig. 1 dargestellt, können hierzu jeweils Schubstangen 23 vorgesehen sein, die mit ihren freien Enden im verriegelten Zustand in jeweils ein am Gehäuse 3 angeordnetes komplementäres Verriegelungselement oder Aufnahmeelement eingreifen.In addition to the locking of the door with the vertical side walls of the housing 3, a locking of the door with the horizontal walls (bottom and lid) of the housing 3 and in the upper and lower region of the door can be done. As in Fig. 1 shown, each push rods 23 may be provided for this purpose, which engage with their free ends in the locked state in each case a housing 3 arranged on the complementary locking element or receiving element.

Wie in Fig. 1 dargestellt, können die Schubstangen mit ihren jeweils inneren Enden mit dem Verriegelungselement 13, jeweils exzentrisch zur Achse 11 verbunden sein. Bei einer Drehung der Achse 11 für das Überführen der Verriegelungselemente 13 in die entriegelte Stellung, beispielsweise um einen Winkel von ca. 60° bis 90°, werden die Schubstangen 23 einwärts (bezogen auf die Türe) bewegt und auf diese Weise ebenfalls in den entriegelten Zustand überführt. Der Drehwinkel wird vorzugsweise so festgelegt, dass die Arme 15 der drehbaren Verriegelungselemente 13 in der entriegelten Position nicht über die Innenwandung oder die Außenabmessung oder Außenkontur der Türe 5 hinausragen.As in Fig. 1 shown, the push rods can be connected with their respective inner ends with the locking element 13, each eccentric to the axis 11. Upon rotation of the axle 11 for transferring the locking elements 13 in the unlocked position, for example by an angle of about 60 ° to 90 °, the push rods 23 are moved inwardly (relative to the door) and in this way also in the unlocked Condition convicted. The angle of rotation is preferably set so that the arms 15 of the rotatable locking elements 13 in the unlocked position do not protrude beyond the inner wall or the outer dimension or outer contour of the door 5.

Selbstverständlich können entsprechende Schubstangen auch an dem weiteren Verriegelungselement 13 an der Gelenkseite der Türe 5 vorgesehen sein, um auf diese Weise die Türe auch an diesen Positionen zusätzlich zu verriegeln. Des Weiteren ist es möglich, entsprechende Schubstangen an jeder beliebigen Position der horizontalen Achse 11 anzuordnen, beispielsweise zusätzlich in der Mitte der Türe bzw. der Achse 11.Of course, corresponding push rods can also be provided on the further locking element 13 on the hinge side of the door 5, in order in this way to additionally lock the door at these positions. Furthermore, it is possible to arrange corresponding push rods at any position of the horizontal axis 11, for example additionally in the middle of the door or the axis 11th

Die Schubstangen müssen nicht, wie in Fig. 1 aus Gründen der Einfachheit schematisch dargestellt, geradlinig ausgebildet sein. Vielmehr können sie praktisch jede beliebige Form aufweisen.The push rods do not have to, as in Fig. 1 schematically illustrated for simplicity, be rectilinear. Rather, they can have virtually any shape.

Das Gehäuse 3 kann im Bereich der Unterkante der Türe 5 ein oder mehrere Auflauframpen 26 aufweisen. Diese dienen dazu, um Toleranzen oder ein Spiel der Anlenkung der Türe, das ggf. erst im Lauf der Zeit durch den Gebrauch des Behälters entstehen kann, auszugleichen. "Hängt die Türe gegenüber dem Gehäuse etwas zu weit nach unten oder schräg, so gleitet die Türe mit ihrer Unterkante auf die schrägen oder gekrümmten Flächen der Auflauframpen 26 auf und gelangt so, trotz des vorhandenen Spiels oder "Hängens" in eine korrekte Schließposition, in der die Verriegelungselemente problemlos und korrekt in die jeweils komplementären Verriegelungselemente eingreifen.The housing 3 may have one or more ramps 26 in the region of the lower edge of the door 5. These serve to compensate for tolerances or a game of articulation of the door, which may eventually arise over time by the use of the container. "If the door is slightly too far down or inclined relative to the housing, the door slides with its lower edge on the sloping or curved surfaces of the ramps 26 and thus, despite the existing game or" hanging "in a correct closed position, in the locking elements engage easily and correctly in the respective complementary locking elements.

Fig. 3 zeigt die Verriegelung der Türe 5 an der linken oberen Ecke des Behälters 1 in Fig. 1 in vergrößerter perspektivischer Darstellung. Fig. 3 shows the lock of the door 5 at the upper left corner of the container 1 in Fig. 1 in an enlarged perspective view.

Wie aus Fig. 3 ersichtlich, ist das komplementäre Verriegelungselement oder Aufnahmeelement 25 mittels eines im Wesentlichen U-förmigen Teils gebildet, welches an der Oberseite des Gehäuses 3 fest angeordnet ist. Die Schubstange 23 greift im verriegelten Zustand mit ihrem freien Ende in den Aufnahmebereich 27 ein, der durch das U-förmige Teil mit seinem über die Gehäusevorderseite hinausragenden Bereich gebildet wird. Für das Entriegeln der Türe 5 wird die Schubstange 23 bei einem Drehen der Achse 11 durch die exzentrische Anbindung der Schubstange an das Verriegelungselement 13 nach unten bzw. bezogen auf die Türe einwärts bewegt. An der oberen Stirnseite 5a der Türe 5, über welche das freie Ende der Schubstange 23 (zumindest im verriegelten Zustand) hinausragt, ist eine Blockiervorrichtung 29 angeordnet. Diese umfasst einen als Schieber ausgebildetes Blockierelement 31, welches mittels einer Feder 33 beaufschlagt ist. Das Blockierelement 31 ist auf der oberen Stirnseite 5a mittels entsprechender Führungselemente 35 verschiebbar gehalten. Die Feder 33 ist in Fig. 3 als Zugfeder ausgebildet. Sie könnte jedoch selbstverständlich auch als Druckfeder ausgebildet und dementsprechend am Blockierelement 31 angreifen, nämlich so, dass das Blockierelement in die blockierte Stellung gebracht wird, wenn sich die Türe 5 öffnet.How out Fig. 3 it can be seen, the complementary locking element or receiving element 25 is formed by means of a substantially U-shaped part, which is fixedly arranged on the upper side of the housing 3. The push rod 23 engages in the locked state with its free end in the receiving area 27, which is formed by the U-shaped part with its projecting beyond the front of the housing area. For unlocking the door 5, the push rod 23 is moved inwardly upon rotation of the axis 11 by the eccentric connection of the push rod to the locking element 13 downwards or relative to the door. At the upper end face 5a of the door 5, beyond which projects the free end of the push rod 23 (at least in the locked state), a blocking device 29 is arranged. This comprises a trained as a slide blocking element 31 which is acted upon by a spring 33. The blocking element 31 is held displaceably on the upper end side 5a by means of corresponding guide elements 35. The spring 33 is in Fig. 3 designed as a tension spring. However, it could of course also be designed as a compression spring and accordingly act on the blocking element 31, namely in such a way that the blocking element is brought into the blocked position when the door 5 opens.

Bei der in Fig. 3 dargestellten Ausführungsform weist das Blockierelement 31 einen Durchbruch 37 auf, durch welchen im verriegelten Zustand das freie Ende der Schubstange 23 ragt.At the in Fig. 3 1, the blocking element 31 has an opening 37, through which the free end of the push rod 23 projects in the locked state.

Das Blockierelement 31 weist einen vertikal nach oben abgewinkelten Teilbereich 31 a auf, der im verriegelten Zustand am linken Schenkel U-förmigen Aufnahmeelements 25 anliegt.The blocking element 31 has a vertically upwardly angled portion 31 a, which rests in the locked state on the left leg U-shaped receiving element 25.

Wird die Türe 5 nach dem Entriegeln und Einwärtsbewegen der Schubstange 23 geöffnet, so wird das Blockierelement 31 in Folge der Federbeaufschlagung nach rechts bewegt, wobei der abgewinkelte Teilbereich 31 a des Blockierelements 31 entlang der Führungsfläche 25a gleitet, die durch die betreffende Außenwandung des U-förmigen Aufnahmeelements 25 gebildet wird.If the door 5 is opened after unlocking and inward movement of the push rod 23, the blocking element 31 is moved to the right as a result of the spring action, wherein the angled portion 31 a of the blocking member 31 slides along the guide surface 25 a, which passes through the respective outer wall of the U- shaped receiving element 25 is formed.

Die Bewegung des Blockierelements 31 nach rechts muss einen Weg umfassen, der ausreicht, um das freie Ende der Schubstange 23 hinsichtlich seiner Verriegelungsbewegung zu blockieren.The movement of the blocking element 31 to the right must include a path sufficient to block the free end of the push rod 23 with respect to its locking movement.

Bei der in Fig. 3 dargestellten Ausführungsform ist vorausgesetzt, dass die Schubstange 23 soweit einwärts bewegt wird, dass sich das freie Ende der Schubstange im entriegelten Zustand unterhalb der Unterseite des Blockierelements 31 befindet und demzufolge das Blockierelement soweit nach rechts verschoben werden kann, bis die Unterseite des Blockierelements 31 die Bewegung der Schubstange 23 nach oben in den verriegelten Zustand blockieren kann.At the in Fig. 3 illustrated embodiment, it is assumed that the push rod 23 is moved inwardly so far that the free end of the push rod is in the unlocked state below the bottom of the blocking element 31 and consequently the blocking element can be moved far enough to the right until the bottom of the blocking element 31, the movement the push rod 23 can block upwards in the locked state.

In einer anderen, nicht dargestellten Ausführungsform ist es selbstverständlich ebenfalls möglich, dass die Schubstange 23 nur soweit einwärts bewegt wird, bis diese außer Eingriff mit dem Aufnahmeelement 25 gerät und in dieser Stellung noch über die Oberseite des Verriegelungselements 31 hinausragt. Bei einer derartigen Vorrichtung muss das Blockierelement 31 so ausgebildet sein, dass der Durchbruch 37 die Freigabebewegung, d. h. das Schieben des Blockierelements 31 nach recht ermöglicht, auch wenn das freie Ende der Schubstange 23 weiterhin durch den Durchbruch hindurchragt. Beispielsweise kann der Durchbruch so weit ausgebildet sein, dass er sich mit einer entsprechenden Höhe bis in den nach oben abgewinkelten Bereich 31 a des Blockierelements 31 fortsetzt.In another embodiment, not shown, it is of course also possible that the push rod 23 is only moved inward until it gets out of engagement with the receiving element 25 and still protrudes in this position over the top of the locking element 31. In such a device, the blocking member 31 must be formed so that the aperture 37, the release movement, d. H. allows the sliding of the blocking element 31 to the right, even if the free end of the push rod 23 still protrudes through the opening. For example, the opening may be formed so far that it continues with a corresponding height to the upwardly angled region 31 a of the blocking element 31.

Die Blockiervorrichtung kann dann so ausgebildet sein, dass das Blockierelement so weit nach rechts verschoben wird, bis der abgewinkelte Bereich 31 a im Bereich der oberen Stirnseite des freien Endes der Schubstange 23 zu liegen kommt. Eine unzulässig weite Aufwärtsbewegung der Schubstange 23 wird dann durch den Teil des Durchbruchs 23 blockiert, der sich bis in den abgewinkelten Bereich 31 a des Blockierelements 31 hineinerstreckt.The blocking device can then be designed so that the blocking element is moved so far to the right until the angled portion 31 a comes to lie in the region of the upper end side of the free end of the push rod 23. An inadmissibly wide upward movement of the push rod 23 is then blocked by the part of the opening 23, which extends into the angled portion 31 a of the blocking element 31.

Durch das Blockieren der Aufwärtsbewegung bzw. Bewegung nach Außen der Schubstangen 23 wird verhindert, dass die Arme 15 der Verriegelungselemente 13 in die Verriegelungsposition oder in eine solche Winkelposition bewegt werden, bei der bei einem Schließen der Türe zumindest das in Fig. 1 dargestellte rechte Verriegelungselement 13 oder der betreffende Bereich des Gehäuses 3 beschädigt würden.By blocking the upward movement or movement to the outside of the push rods 23 prevents the arms 15 of the locking elements 13 are moved to the locking position or in such an angular position in which at least when closing the door in Fig. 1 shown right locking element 13 or the relevant area of the housing 3 would be damaged.

Bei einem Schließen der Türe wird das Blockierelement 31 gegen die Kraft der Feder 33 nach links verschoben, sobald die Stirnseite des abgewinkelten Teilbereichs 31a mit dem Aufnahmeelement 25 in Berührung kommt. Die Führungsfläche 25a ist dabei so ausgeführt, dass bei einem weiteren Schließen der Türe das Blockierelement 31 ohne allzu große Krafteinwirkung beim Schließen der Türe nach links verschoben wird. Das Blockierelement 31 ist dabei hinsichtlich des Durchbruchs 37 so ausgeführt, dass ein Verriegeln der Vorrichtung, d. h. ein nach außen Bewegen der Schubstangen 23 erst dann ermöglicht wird, wenn sich das freie Ende der Schubstange 23 im Bereich des Aufnahmebereichs 27 befindet, der durch das Aufnahmeelement 25 gebildet ist. Damit wird eine Beschädigung der Türe bzw. des Behälters in Folge eines Schließens der Türe bei gleichzeitig verriegelter Verriegelungsvorrichtung sicher vermieden.When the door is closed, the blocking element 31 is displaced to the left against the force of the spring 33 as soon as the end face of the angled portion 31a comes into contact with the receiving element 25. The guide surface 25a is designed so that in a further closing of the door, the blocking element 31 is moved without too much force when closing the door to the left. The blocking element 31 is designed with respect to the opening 37 so that a Locking of the device, ie an outward movement of the push rods 23 is made possible only when the free end of the push rod 23 is in the region of the receiving portion 27 which is formed by the receiving element 25. In order to avoid damage to the door or the container as a result of closing the door at the same time locked locking device safely.

Am Teilbereich 31a und an der Führungsfläche 25a können Vorfixierelemente 31b, 25b vorgesehen sein, die beispielsweise als erhabene Prägungen in diesen Teilen ausgebildet sein können. Die Vorfixierelemente können jedoch selbstverständlich auch als eigenständige Elemente ausgebildet sein.Vorfixierelemente 31b, 25b may be provided on the portion 31a and on the guide surface 25a, which may be formed, for example, as raised embossments in these parts. Of course, the prefixing can also be designed as separate elements.

Die Vorfixierelemente 31 b, 25b sind so ausgebildet, dass bei einem Schließen der Türe 5 ein Einrasten oder Vorfixieren der Türe in einer Stellung erfolgt, in der die Blockiervorrichtung die Verriegelungsvorrichtung bereits freigegeben hat und in der vorzugsweise bei einer Betätigung der Verriegelungsvorrichtung ein Verriegeln und endgültiges Schließen der Türe (um den verbleibenden geringen Öffnungswinkel) erfolgt, ohne dass die Bedienperson aktiv ein zusätzliches Schließen der Türe bewirken müsste.The Vorfixierelemente 31 b, 25 b are formed so that when closing the door 5 a latching or prefixing of the door takes place in a position in which the blocking device has already released the locking device and in the preferably upon actuation of the locking device locking and final Closing the door (by the remaining small opening angle) takes place without the operator actively having to effect an additional closing of the door.
