Description

Die Erfindung betrifft eine Türverriegelungseinrichtung für eine Tür, insbesondere für eine Tür einer Waschmaschine, sowie deren Verwendung.The invention relates to a door locking device for a door, in particular for a door of a washing machine, and the use thereof.

Im Stand der Technik ist bekannt, dass zur Verriegelung einer Tür oder Klappe oder dergleichen eine Drehfalle eingesetzt wird, um die Tür oder die Klappe in einer Verschlussstellung zu halten. Die Drehfalle weist hierbei eine Ausnehmung auf, die in der Schließlage einen Schließbolzen oder Schließbügel während der Schließbewegung der Tür aufnimmt, wobei die Drehfalle zum Verriegeln in einer Verriegelungsstellung so verschwenkt wird, dass der Schließbolzen oder Schließbügel in seiner Bewegung blockiert ist. Um die Drehfalle in der Verriegelungsstellung zu halten, ist eine Sperrklinke oder dergleichen vorgesehen, um die Verschwenkung der Drehfalle in die den Schließbolzen oder Schließbügel freigebende Entriegelungsstellung zu verhindern.It is known in the prior art that a rotary latch is used to lock a door or flap or the like in order to hold the door or flap in a closed position. The rotary latch has a recess in the closed position which receives a locking bolt or locking bracket during the closing movement of the door, the rotary latch being pivoted in a locking position so that the locking bolt or locking bracket is blocked in its movement. In order to keep the rotary latch in the locking position, a pawl or the like is provided in order to pivot the rotary latch into the unlocking position releasing the locking bolt or locking bracket to prevent.

Beispielsweise ist in DE 40 31 077 A1 eine elektromagnetische Türverriegelung mit einer Drehfalle offenbart.For example, in DE 40 31 077 A1 discloses an electromagnetic door lock with a rotary latch.

Außerdem ist in DE 198 28 830 A1 eine Waschmaschine bekannt, die eine Tür und einen Verschluss aufweist, der eine elektromagnetische Öffnungseinrichtung und eine über eine Zugeinrichtung zu betätigende Notentriegelungseinrichtung aufweist. Ferner ist in DE 198 48 275 A1 eine Vorrichtung zum Verriegeln einer Tür eines Haushaltsgeräts, insbesondere einer Waschmaschine, beschrieben.In addition, in DE 198 28 830 A1 a washing machine is known which has a door and a lock, which has an electromagnetic opening device and an emergency release device to be operated via a pulling device. Furthermore, in DE 198 48 275 A1 a device for locking a door of a household appliance, in particular a washing machine, described.

Die Aufgabe der Erfindung besteht darin, eine einfach aufgebaute und kostengünstige Türverriegelung, insbesondere für eine Waschmaschine, bereitzustellen.The object of the invention is to provide a simply constructed and inexpensive door lock, in particular for a washing machine.

Gelöst wird diese Aufgabe durch eine Türverriegelungseinrichtung für eine Tür, insbesondere für eine Tür einer Waschmaschine, mit einer verschwenkbaren Drehfalle für einen Türhaken, wobei die verschwenkbare Drehfalle an einem Schwenkkörper angeordnet ist, wobei die Drehfalle eine Ausnehmung zur Aufnahme eines Verriegelungskörpers für die Drehfalle aufweist, wobei ein Verriegelungskörper zur Verriegelung der Drehfalle in deren Schließstellung vorgesehen ist, wobei der Verriegelungskörper mit einem Anker verbunden ist, wobei der Anker von einer bestrombaren Spule umgeben ist und bei Bestromung der Spule der Anker und der Verriegelungskörper in Schließstellung der Drehfalle linear bewegbar sind oder bewegt werden, so dass der Verriegelungskörper in einer Sperrstellung in der Ausnehmung der Drehfalle angeordnet wird oder anordbar ist.This object is achieved by a door locking device for a door, in particular for a door of a washing machine, with a pivotable rotary latch for a door hook, the pivotable rotary latch being arranged on a swivel body, the rotary latch having a recess for receiving a locking body for the rotary latch, wherein a locking body is provided for locking the rotary latch in its closed position, the locking body being connected to an armature, the armature being surrounded by an energizable coil and, when the coil is energized, the armature and the locking body can be moved or moved linearly in the closed position of the rotary latch are so that the locking body is arranged in a locking position in the recess of the rotary latch or can be arranged.

Die Erfindung beruht auf dem Gedanken, dass bei Bestromung einer Spule der von der Spule umgebene Anker linear bewegbar ist, wobei der Anker bei Nichtbestromung in seine Ruheposition mittels einer Feder bewegt wird oder bewegbar ist. Mittels des Ankers und der Spule wird ein Aktuator bereitgestellt bzw. ausgebildet, wobei zum Verriegeln und Entriegeln der Tür, beispielsweise einer Waschmaschine, ein Umschalten einer Stromquelle für die Spule nicht erforderlich ist. Hierdurch wird beispielsweise ein einfacher Aufbau erreicht, da gegenüber dem Stand der Technik, bei dem aufwändige und teure Umkehrmagneten für Verriegelungen für Waschmaschinen eingesetzt werden, hingegen bei der erfindungsgemäßen Verriegelung bzw. Türverriegelungseinrichtung eine Ausbildung ohne Joche sowie ohne Permanentmagnete erreicht wird. Darüber hinaus weist die Türverriegelungseinrichtung vorteilhafterweise ausschließlich eine Spule für den zu bewegenden Anker auf.The invention is based on the idea that when energized one The armature surrounded by the coil is linearly movable, the armature being moved or being movable into its rest position by means of a spring when no current is supplied. An actuator is provided or formed by means of the armature and the coil, it not being necessary to switch over a current source for the coil to lock and unlock the door, for example a washing machine. In this way, for example, a simple structure is achieved, since, in contrast to the prior art, in which complex and expensive reversing magnets are used for locking devices for washing machines, training in the locking device or door locking device according to the invention is achieved without yokes and without permanent magnets. In addition, the door locking device advantageously has only one coil for the armature to be moved.

Darüber hinaus zeichnet sich eine Weiterbildung der Türverriegelungseinrichtung dadurch aus, dass eine Ankerfeder für den Anker vorgesehen ist, wobei insbesondere die Ankerfeder eingerichtet ist, bei nicht-bestromter Spule den Anker in einer Ruheposition zu halten und bei Bestromung der Spule der linearen Bewegung des Ankers entgegenzuwirken.In addition, a further development of the door locking device is characterized in that an armature spring is provided for the armature, the armature spring in particular being designed to hold the armature in a rest position when the coil is not energized and to counteract the linear movement of the armature when the coil is energized .

Vorzugsweise ist gemäß einer Ausführungsform der Türverriegelungseinrichtung vorgesehen, dass der Anker unter Verwendung eines Stößels mit einem Spannwerk für den Verriegelungskörper verbunden ist. Hierbei ist das Spannwerk derart eingerichtet, dass bei Bestromung der Spule mittels des dadurch bewegten Ankers der Türverriegelungseinrichtung der Verriegelungskörper in eine Sperrstellung bewegt wird und mittels des Spannwerks in der Sperrstellung positioniert bzw. gehalten wird, auch wenn die Spule nach der linearen Bewegung des Ankers nicht mehr bestromt wird oder ist. Um den Verriegelungskörper aus seiner Sperrstellung, in der die Drehfalle verriegelt ist und nicht bewegbar ist, zu entfernen, wird nach einer Phase der Nichtbestromung der Spule die Spule wieder bestromt, um den linear bewegbaren Anker zu bewegen, so dass dadurch der Verriegelungskörper aus seiner durch das Sperrspannwerk gehaltenen Schließstellung in eine Entsperrposition gebracht wird, wobei gleichzeitig die Halteposition bzw. die Sperrstellung des Verriegelungskörpers durch das Sperrspannwerk gelöst wird. Dazu ist in einer Weiterbildung vorgesehen, dass das Sperrspannwerk eine mit dem Stößel verbundene Krone und eine mit der Krone zusammenwirkende und mit dem Verriegelungskörper verbundene oder zusammenwirkende Drehkrone aufweist.According to one embodiment of the door locking device, it is preferably provided that the armature is connected to a tensioning mechanism for the locking body using a plunger. Here, the tensioning mechanism is set up in such a way that when the coil is energized by means of the armature of the door locking device thereby moved, the locking body is moved into a locking position and is positioned or held in the locking position by means of the tensioning mechanism, even if the coil does not move after the linear movement of the armature is or is more energized. To the locking body from its locked position in which the If the catch is locked and cannot be moved, after a phase of de-energization of the coil, the coil is energized again in order to move the linearly movable armature, so that the locking body is brought from its closed position held by the locking mechanism to an unlocked position, at the same time the holding position or the locking position of the locking body is released by the locking mechanism. For this purpose, in a further development it is provided that the locking mechanism has a crown connected to the tappet and a rotating crown which interacts with the crown and is connected to or interacts with the locking body.

Außerdem ist gemäß einem weiteren Aspekt der Erfindung vorgesehen, dass der Stößel und/oder das Sperrspannwerk, insbesondere die Krone und die Drehkrone des Sperrspannwerks, in einem Führungsrohr aufgenommen sind. Dadurch ergibt sich eine verbesserte Führung des Stößels sowie des Sperrspannwerks, insbesondere der Krone und der Drehkrone im Inneren des Führungsrohres.In addition, it is provided according to a further aspect of the invention that the tappet and / or the locking mechanism, in particular the crown and the rotating crown of the locking mechanism, are received in a guide tube. This results in improved guidance of the tappet and the locking mechanism, in particular the crown and the rotating crown in the interior of the guide tube.

Ferner zeichnet sich eine Ausgestaltung der Türverriegelungseinrichtung dadurch aus, dass zum Entriegeln der Sperrstellung des Verriegelungskörpers durch eine weitere Bestromung der Spule der Anker linear bewegbar ist oder bewegt wird, so dass der Verriegelungskörper aus der Sperrstellung bewegt wird.Furthermore, an embodiment of the door locking device is characterized in that, in order to unlock the locking position of the locking body, the armature can be moved or moved linearly by further energization of the coil, so that the locking body is moved out of the locking position.

Vorteilhafterweise ist eine am Verriegelungskörper angreifende Entriegelungsfeder vorgesehen, wobei die Entriegelungsfeder eingerichtet ist, den Verriegelungskörper in eine Entsperrposition bzw. Ruheposition zu drücken.An unlocking spring acting on the locking body is advantageously provided, the unlocking spring being set up to press the locking body into an unlocked position or rest position.

Um beispielsweise eine Tür einer Waschmaschine über den Türhaken permanent unter einer Vorspannung zu halten, ist erfindungsgemäß vorgesehen, dass die Drehfalle mittels einer am Schwenkkörper vorgesehenen Feder in Schließstellung der Drehfalle vorgespannt ist. Mittels der Feder wird eine Vorspannung bewirkt, wodurch die Tür oder der Deckel, zum Beispiel einer Waschmaschine, in eine Dichtung der Türöffnung gedrückt wird. Bei Alterung oder einer Schrumpfung der Dichtung wird vorteilhafterweise die Tür über die Feder bzw. die Federmechanik weiterhin mit einer konstanten Kraft in die Dichtung gedrückt, wodurch für lange Zeit die Dichtkraft konstant gehalten wird.For example, in order to keep a door of a washing machine under the pretension permanently under the door hook, the invention provided that the rotary latch is biased in the closed position of the rotary latch by means of a spring provided on the swivel body. A preload is brought about by means of the spring, as a result of which the door or the cover, for example a washing machine, is pressed into a seal in the door opening. When the seal ages or shrinks, the door is advantageously pressed into the seal with a constant force via the spring or the spring mechanism, as a result of which the sealing force is kept constant for a long time.

Dazu ist in einer Ausgestaltung vorgesehen, dass die Feder des Schwenkkörpers für die Drehfalle zwischen zwei voneinander beabstandeten Haltestücken angeordnet ist, wobei ein erstes Haltestück mit der Drehfalle drehbar verbunden ist und das zweite Haltestück um eine Schwenkachse schwenkbar gelagert ist. Die Schwenkachse der Drehfalle und die Schwenkachse des Schwenkkörpers sind vorzugsweise parallel zueinander ausgerichtet.For this purpose, in one embodiment it is provided that the spring of the swivel body for the rotary latch is arranged between two spaced-apart holding pieces, a first holding piece being rotatably connected to the rotary latch and the second holding piece being pivotably mounted about a pivot axis. The pivot axis of the rotary latch and the pivot axis of the pivot body are preferably aligned parallel to one another.

Außerdem ist vorteilhafterweise der Anker aus einem weichmagnetischen Material hergestellt.In addition, the armature is advantageously made of a soft magnetic material.

Ferner zeichnet sich eine Ausgestaltung der Türverriegelungseinrichtung dadurch aus, dass ein manuell betätigbarer Notentriegelungskörper am Anker vorgesehen ist. Mittels des manuell betätigbaren Notentriegelungskörpers ist es möglich, den Anker bei einer Nichtbestromung der Spule linear zu bewegen, um beispielsweise den Verriegelungskörper aus der Sperrstellung in der Ausnehmung der Drehfalle zu entfernen.Furthermore, an embodiment of the door locking device is characterized in that a manually operated emergency unlocking body is provided on the anchor. By means of the manually operated emergency release body, it is possible to move the armature linearly when the coil is not energized, for example to remove the locking body from the locked position in the recess of the rotary latch.

Darüber hinaus ist vorgesehen, dass die Türverriegelungseinrichtung in einem Gehäuse angeordnet ist, wodurch sich ein vereinfachter Einbau der Türverriegelungseinrichtung, beispielsweise in einer Waschmaschine, ergibt.In addition, it is provided that the door locking device is arranged in a housing, which simplifies the installation of the door locking device, for example in a Washing machine, results.

Darüber hinaus wird die Aufgabe gelöst durch eine Verwendung einer voranstehend beschriebenen Türverriegelungseinrichtung für eine Tür in einer Waschmaschine oder einem Haushaltsgerät. Im Rahmen der Erfindung wird unter einer Tür auch ein Deckel oder eine Klappe einer Waschmaschine verstanden, der bzw. die in entsprechender Weise mittels der Verriegelungseinrichtung ebenfalls verriegelbar ist.In addition, the object is achieved by using a door locking device described above for a door in a washing machine or a household appliance. In the context of the invention, a door is also understood to mean a lid or a flap of a washing machine, which can also be locked in a corresponding manner by means of the locking device.

In Fig. 1 ist schematisch eine perspektivische Ansicht einer Türverriegelungseinrichtung 10 gezeigt. In Fig. 2 ist ein Querschnitt durch die Türverriegelungseinrichtung 10 schematisch dargestellt. Die Türverriegelungseinrichtung 10 kann hierbei Bestandteil einer Waschmaschine sein. Die Türverriegelungseinrichtung 10 dient hierbei zur Verriegelung einer Tür oder eines Deckels, die bzw. der mit einem Türhaken 60 verbunden ist.In Fig. 1 a perspective view of a door locking device 10 is shown schematically. In Fig. 2 a cross section through the door locking device 10 is shown schematically. The door locking device 10 can be part of a washing machine. The door locking device 10 serves to lock a door or a cover which is connected to a door hook 60.

Die Türverriegelungseinrichtung 10 weist ein Gehäuse 12 auf. Im Inneren des Gehäuses 12 ist hierbei eine bestrombare Spule 14 vorgesehen, die einen linear bewegbaren Anker 16 umgibt. Die bestrombare Spule 14 ist mit einer hier nicht dargestellten, schaltbaren Stromquelle verbunden.The door locking device 10 has a housing 12. In the interior of the housing 12, an energizable coil 14 is provided, which surrounds a linearly movable armature 16. The energizable coil 14 is connected to a switchable current source, not shown here.

Der Anker 16 ist vorzugsweise aus einem weichmagnetischen Material hergestellt. An einer Seite des Ankers 16, in Fig. 2 an dessen Unterseite, ist eine Druckfeder 18 angeordnet, um den Anker 16 in seiner Ruheposition bei nicht-bestrombarer Spule 14 zu halten. Die Druckfeder 18 ist beispielsweise als Spiralfeder oder dergleichen ausgebildet. An der der Druckfeder 18 abgewandten Seite des Ankers 16 ist ferner ein Notentriegelungsknopf oder Notentriegelungskörper 20 mit dem Anker 16 verbunden, der in einer Öffnung des Gehäuses 12 in der Ruheposition des Ankers 16 angeordnet ist. Der manuell betätigbare Notentriegelungskörper 20 kann auch in einer Ausgestaltung aus dem Gehäuse 12 herausragen.The armature 16 is preferably made of a soft magnetic material. On one side of the anchor 16, in Fig. 2 on its underside, a compression spring 18 is arranged to hold the armature 16 in its rest position when the coil 14 is not energized. The compression spring 18 is designed, for example, as a spiral spring or the like. On the side of the armature 16 facing away from the compression spring 18, an emergency release button or body 20 is also connected to the armature 16, which is arranged in an opening of the housing 12 in the rest position of the armature 16. The manually operated emergency release body 20 can also in one Project configuration from the housing 12.

Ferner ist der bei Bestromung der Spule 14 linear bewegbare Anker 16 über einen Stößel 22 mit einem Sperrspannwerk 24 verbunden. Das Sperrspannwerk 24 umfasst hierbei eine mit dem Stößel 22 verbundene Krone 26, die mit einer an der Krone 26 angeordneten Drehkrone 28 zusammenwirkt. Hierbei weisen die Krone 26 und die Drehkrone 28 jeweils gezackte und einander zugewandte Endseiten auf, die miteinander verzahnen können.Furthermore, the armature 16, which is linearly movable when the coil 14 is energized, is connected to a locking tensioning mechanism 24 via a plunger 22. The locking tensioning mechanism 24 in this case comprises a crown 26 connected to the plunger 22, which cooperates with a rotating crown 28 arranged on the crown 26. Here, the crown 26 and the rotating crown 28 each have serrated and mutually facing end faces which can interlock.

Der Stößel 22 sowie das Sperrspannwerk 24 sind im Inneren eines Führungsrohrs 30 angeordnet, wobei im Bereich der Drehkrone 28 die Innenseite des Führungsrohrs 30 Nuten für an der Außenseite der Drehkrone 28 angeordnete Außenkörper aufweist. Die Nuten des Führungsrohrs 30 sowie die Außenkörper der Drehkrone 28 wirken hierbei zusammen. Die Nuten an der Innenseite des Führungsrohrs 30 im Bereich der Drehkrone 28 sind hierbei in Umfangsrichtung angeordnet, wobei in Umfangsrichtung die Nuten für die Außenkörper der Drehkrone 28 alternierend verschiedene Tiefen aufweisen. In den Nuten des Führungsrohrs 30 werden hierbei die Außenkörper der Drehkrone 28 entlang der Längserstreckung des Führungsrohrs 30 geführt.The plunger 22 and the locking mechanism 24 are arranged in the interior of a guide tube 30, the inside of the guide tube 30 having grooves for outer bodies arranged on the outside of the rotary crown 28 in the region of the rotary crown 28. The grooves of the guide tube 30 and the outer body of the rotating crown 28 interact here. The grooves on the inside of the guide tube 30 in the region of the rotating crown 28 are arranged in the circumferential direction, the grooves for the outer bodies of the rotating crown 28 alternately having different depths in the circumferential direction. In this case, the outer bodies of the rotating crown 28 are guided in the grooves of the guide tube 30 along the longitudinal extent of the guide tube 30.

An der von der Krone 26 abgewandten Seite der Drehkrone 28 ist die Drehkrone 28 mit einem Verriegelungskörper 32 in Kontakt oder verbunden. Der Verriegelungskörper 32 ist endseitig von einem Haltekörper 34 umgeben. Auf der Außenseite des Verriegelungskörpers 32 ist dieser von einer Entriegelungsfeder 36 umgeben, die sich auf der Halterung bzw. auf dem Haltekörper 34 abstützt.On the side of the rotary crown 28 facing away from the crown 26, the rotary crown 28 is in contact or connected to a locking body 32. The locking body 32 is surrounded at the end by a holding body 34. On the outside of the locking body 32, the latter is surrounded by an unlocking spring 36 which is supported on the holder or on the holding body 34.

Dem Verriegelungskörper 32 gegenüber ist an dessen Unterseite eine verschwenkbare Drehfalle 40 angeordnet, die an der Unterseite mit einem verschwenkbaren Schwenkkörper 42 auf der von dem Verriegelungskörper abgewandten Seite der Drehfalle 40 verbunden ist. Der Schwenkkörper 42 besteht hierbei aus zwei Haltestücken 44, 46, zwischen denen eine Feder 48 angeordnet ist, um die Haltestücke 44, 46 auseinanderzudrücken.A locking pivot 40 is arranged on the underside of the locking body 32, on the underside is connected to a pivotable swivel body 42 on the side of the rotary latch 40 facing away from the locking body. The swivel body 42 here consists of two holding pieces 44, 46, between which a spring 48 is arranged in order to push the holding pieces 44, 46 apart.

In Fig. 3a, 3b ist jeweils der Bereich zwischen der Drehfalle 40 und dem Verriegelungskörper 32 schematisch gezeigt, wobei in Fig. 3a die Drehfalle 40 in ihrer Schließstellung und der Verriegelungskörper 32 in Sperrstellung bzw. in einer Verriegelungsposition und in Fig. 3b die Drehfalle 40 in einer Öffnungsstellung sowie der Verriegelungskörper 32 in einer Ruheposition bzw. in einer Entriegelungsposition angeordnet sind. Die Drehfalle 40 weist eine U-förmige Ausnehmung 50 auf, in der eine Querstrebe 62 eines Türhakens 60 (vgl. Fig. 1), beispielsweise einer Tür einer Waschmaschine, aufgenommen wird. An der Oberseite der Drehfalle 40, die dem Verriegelungskörper 32 zugewandt ist, weist die Drehfalle 40 eine Ausnehmung 52 auf, in der das freie Ende des Verriegelungskörpers 32 in Schließstellung der Drehfalle 40 angeordnet wird (vgl. Fig. 3a), um die Drehfalle 40 zu verriegeln.In 3a, 3b the area between the catch 40 and the locking body 32 is shown schematically, wherein in Fig. 3a the rotary latch 40 in its closed position and the locking body 32 in the locked position or in a locking position and in Fig. 3b the rotary latch 40 are arranged in an open position and the locking body 32 in a rest position or in an unlocking position. The rotary latch 40 has a U-shaped recess 50 in which a cross strut 62 of a door hook 60 (cf. Fig. 1 ), for example a door of a washing machine. At the top of the rotary latch 40, which faces the locking body 32, the rotary latch 40 has a recess 52 in which the free end of the locking body 32 is arranged in the closed position of the rotary latch 40 (cf. Fig. 3a ) to lock the catch 40.

In Fig. 1 ist schematisch der Türhaken 60, der eine Querstrebe 62 aufweist, dargestellt, wobei die in Fig. 1 dargestellte Türverriegelungseinrichtung 10 sich in der Schließstellung befindet. In der Schließstellung der Drehfalle 40 ist die Querstrebe 62 des Türhakens 60 in der Ausnehmung 50 der Drehfalle 40 angeordnet bzw. aufgenommen (vgl. Fig. 3a). Im entriegelten Zustand (vgl. Fig. 3b) ist die Drehfalle 40 über die Feder 48, die vorzugsweise als Vollrastfeder ausgebildet ist, vorgespannt, so dass die Drehfalle 40 im offenen Zustand sicher verbleibt. Beim Verschließen einer Tür, zum Beispiel einer Waschmaschine, wird der Türhaken 60 in Richtung der Drehfalle 40 bewegt, so dass die Querstrebe 62 in der Ausnehmung 50 der Drehfalle 40 positioniert wird, wodurch der Türhaken 60 beim Verschließen der Tür die Drehfalle 40 dreht. Dabei spannt die Feder 48 die Drehfalle 40, so dass die Drehfalle 40 den Türhaken 60 in Richtung der gesamten Türverriegelungseinrichtung 10 zieht. Hierdurch wird eine hohe Dichtkraft der gehaltenen Tür erreicht.In Fig. 1 is shown schematically the door hook 60, which has a cross strut 62, the in Fig. 1 Door locking device 10 shown is in the closed position. In the closed position of the rotary latch 40, the cross strut 62 of the door hook 60 is arranged or received in the recess 50 of the rotary latch 40 (cf. Fig. 3a ). In the unlocked state (cf. Fig. 3b ), the rotary latch 40 is biased by the spring 48, which is preferably designed as a full detent spring, so that the rotary latch 40 remains securely in the open state. When closing a door, for example a washing machine, the door hook 60 is moved in the direction of the rotary latch 40, so that the cross strut 62 in the recess 50 of the rotary latch 40 is positioned, whereby the door hook 60 rotates the rotary latch 40 when the door is closed. The spring 48 tensions the rotary latch 40 so that the rotary latch 40 pulls the door hook 60 in the direction of the entire door locking device 10. As a result, a high sealing force of the held door is achieved.

Um die Tür zu verriegeln, wird in der Verriegelungsposition des Türhakens 60 (vgl. Fig. 3a) die Spule 14 bestromt, so dass der linear bewegbare Anker 16 gegen die Druckfeder 18 und gegen die Entriegelungsfeder 36 und dadurch der mit dem Anker 16 verbundene Stößel 22, die Krone 26, die Drehkrone 28 und der Verriegelungskörper 32 in Richtung der Drehfalle 40 bewegt werden und der Verriegelungskörper 32 mit seinem freien Ende in der Ausnehmung 52 der Drehfalle 40 angeordnet ist. Wird anschließend die Spule 14 nicht mehr bestromt, wird der Anker 16 zusammen mit dem Stößel 22 und der Krone 26 mittels der Feder bzw. Druckfeder 18 zurückbewegt. Hierbei verbleibt die Drehkrone 28 zusammen mit dem Verriegelungskörper 32 in der Position und wird mittels des Sperrspannwerks 24 in dieser Position gehalten, um die Drehfalle 40 zu verriegeln. Anschließend wird bei einer weiteren Bestromung der Spule 14 der Anker 16 zusammen mit dem Stößel 22 und der Krone 26 in Richtung der Drehfalle 40 bewegt, wodurch die Halteposition des Sperrspannwerks 24 für den Verriegelungskörper 32 gelöst wird, so dass der Verriegelungskörper 32 mittels der Entriegelungsfeder 36 die Drehfalle 40 freigibt. Durch die Freigabe des Türhakens 60 kann anschließend der Türhaken 60 aus der Ausnehmung 50 der Drehfalle 40 nach Drehen der Drehfalle 40 entfernt werden (vgl. Fig. 3b).In order to lock the door, the door hook 60 (cf. Fig. 3a ) energizes the coil 14 so that the linearly movable armature 16 moves against the compression spring 18 and against the unlocking spring 36 and thereby the plunger 22 connected to the armature 16, the crown 26, the rotating crown 28 and the locking body 32 in the direction of the rotary latch 40 are and the locking body 32 is arranged with its free end in the recess 52 of the rotary latch 40. If the coil 14 is then no longer energized, the armature 16 is moved back together with the plunger 22 and the crown 26 by means of the spring or compression spring 18. Here, the rotating crown 28 remains in position together with the locking body 32 and is held in this position by means of the locking mechanism 24 in order to lock the rotary latch 40. Subsequently, when the coil 14 is energized further, the armature 16 is moved together with the plunger 22 and the crown 26 in the direction of the rotary latch 40, as a result of which the holding position of the locking tension mechanism 24 for the locking body 32 is released, so that the locking body 32 by means of the unlocking spring 36 the catch 40 releases. By releasing the door hook 60, the door hook 60 can then be removed from the recess 50 of the rotary latch 40 after turning the rotary latch 40 (cf. Fig. 3b ).
