Description

Die vorliegende Erfindung betrifft ein Riegelwerk für Türen.The present invention relates to a boltworks for doors.

In der DE 100 20 825 A1 ist eine Verriegelungsvorrichtung für Flugzeuge beschrieben, bei welcher eine zusätzliche Bewegung eines Antriebs möglich ist, sobald die Verriegelungslage eingenommen ist. Hierbei lässt sich der Antrieb nach Erreichen der Verriegelungslage über einen Restweg verstellen.In the DE 100 20 825 A1 a locking device for aircraft is described, in which an additional movement of a drive is possible once the locking position is taken. Here, the drive can be adjusted after reaching the locking position over a residual distance.

Bei einer Reihe von Einsatzfeldern weisen Türen zusätzlich zu einer einfachen Verriegelung Sonderfunktionen auf, wie z.B. dem Abdichten der geschlossenen Türe mittels aufpumpbaren Dichtungen oder dem zusätzlichen Arretieren der geschlossenen Türe mittels weiterer Riegel. So wird beispielsweise in der DE 19 615 055 A1 eine wasserdichte, mittels eines aufblasbaren Gummischlauches verschließbare Türe beschrieben.In a number of application fields, doors have special functions in addition to a simple locking, such as the sealing of the closed door by means of inflatable seals or the additional locking of the closed door by means of another bolt. For example, in the DE 19 615 055 A1 a waterproof, closable by means of an inflatable rubber hose door described.

Diese Sonderfunktionen werden z.B. manuell mittels eines zusätzlichen Schalters oder automatisch sensorgesteuert nach dem Schließen und Verriegeln der Türe betätigt. Hierbei ist eine zusätzliche Betätigung eines Bedienelementes für die Sonderfunktion erforderlich, was umständlich ist. Ferner besteht die Gefahr, dass vergessen wird, die Sonderfunktion zu betätigen, oder dass es unklar ist, ob diese ausgelöst wurde.These special functions are e.g. manually operated by means of an additional switch or automatically controlled by the sensor after closing and locking the door. Here, an additional operation of a control element for the special function is required, which is cumbersome. Furthermore, there is a risk that it will be forgotten to operate the special function, or that it is unclear whether it has been triggered.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Riegelwerk für Türen zur Verfügung zu stellen, welches es ermöglicht, mittels eines Bedienelementes die Türe zu verriegeln, und einen zusätzlichen Stellbereich aufweist, bei dessen Durchfahren eine Sonderfunktion ausgelöst wird.It is therefore an object of the present invention to provide a bolt mechanism for doors, which makes it possible to lock the door by means of a control element, and has an additional adjustment range, when driving through a special function is triggered.

Diese Aufgabe wird gelöst durch ein Riegelwerk mit den Merkmalen des Patentanspruchs 1.This object is achieved by a bolt mechanism with the features of patent claim 1.

Ferner soll es für den Bediener durch ein Force-Feedback am Bedienelement spürbar sein, wenn der zusätzliche Stellbereich durchfahren wird.Furthermore, it should be felt by the operator by a force feedback on the control element when the additional adjustment range is traversed.

Die Erfindung wird im Folgenden anhand von Ausführungsbeispielen unter Bezugnahme auf die beiliegenden Figuren der Zeichnung näher erläutert. Hierbei zeigt:

Fig. 1 zeigt eine schematische Querschnittsansicht in der Ebene eines ersten Schiebers 30 eines erfindungsgemäßen mehrstufigen Riegelwerkes gemäß einem Ausführungsbeispiel. Eine an einer Türe drehfähig angeordnete Sperrriegeleinheit 10 ist links in Fig. 1 im Eingriff mit einem an der Türzarge fest angeordneten Bolzen 20 dargestellt. Die Sperrriegeleinheit 10 ist gelenkig mit einem rechts daneben in Fig. 1 dargestellten ersten verschiebbaren Schieber 30 verbunden. Der erste Schieber 30 ist in einer Endlage E1 dargestellt. Nach rechts versetzt ist eine Ausgangslage A1 angedeutet. Die Stellung der Sperrriegeleinheit 10 entspricht der Stellung des ersten Schiebers 30 in der Endlage E1, d.h. in dem verriegelten Zustand. Eine Scheibe 35 weist eine Mitnehmernut 32 auf, die einen bogenförmigen Verlauf aufweist. Ein Mitnehmerzapfen 54, der an einer um einen Drehpunkt D verdrehbaren, mit einem nicht dargestellten Türhebel verbundenen Scheibe 50 angebracht ist, ist im Eingriff mit der Mitnehmernut 32 dargestellt. Zum Zwecke der Erläuterung ist der Mitnehmerzapfen 54 in Fig. 1 in einer ersten Position, in welcher die Tür verriegelt ist, voll ausgezeichnet dargestellt und in einer zweiten Position, mit 54' bezeichnet, gestrichelt eingetragen. Der nicht dargestellte Türhebel ist üblicherweise über einen Vierkant 51 mit der Scheibe 50 verbunden. Entsprechend der dargestellten Ausgangslage A1 und Endlage E1 des ersten Schiebers 30 ist die Scheibe 50 mit dem Mitnehmerzapfen 54 in einer Ausgangsdrehlage WA und in einer ersten Winkelstellung W1 dargestellt. Ferner ist noch eine dritte Winkelstellung des Türhebels bzw. der Scheibe 50 mit W2 angegeben. Federelemente 52a und 52b sind zu beiden Enden der Mitnehmernut 32 hin so angebracht, dass sie zwischen dem jeweiligen Boden der Mitnehmernut 32 und dem Mitnehmerzapfen 54 angeordnet sind. Der erste Schieber 30 weist ferner an seiner rechten Seite in Fig. 1 eine Führung 34 auf, mittels der er an seinem rechten Ende bzw. zum Türband weisenden Ende im Wesentlichen horizontal verschiebbar geführt ist. Fig. 1 shows a schematic cross-sectional view in the plane of a first slider 30 of a multistage bar according to the invention according to an embodiment. A rotatably mounted on a door lock bar unit 10 is left in Fig. 1 shown engaged with a fixed to the door frame bolt 20. The locking bar unit 10 is hinged with a right next to it Fig. 1 shown connected first sliding slide 30. The first slider 30 is shown in an end position E1. Offset to the right is an initial position A1 indicated. The position of the locking bar unit 10 corresponds to the position of the first slider 30 in the end position E1, ie in the locked state. A disk 35 has a cam groove 32, which has a curved course. A driving pin 54, which is attached to a rotatable about a pivot point D, connected to a door lever, not shown, disc 50 is shown in engagement with the cam groove 32. For purposes of explanation, the drive pin 54 is shown in FIG Fig. 1 in a first position, in which the door is locked, fully illustrated and shown in a second position, denoted by 54 ', dashed. The door lever, not shown, is usually connected via a square 51 with the disc 50. Corresponding to the illustrated starting position A1 and end position E1 of the first slider 30, the disk 50 is shown with the driving pin 54 in an output rotational position WA and in a first angular position W1. Furthermore, there is a third angular position of the door lever or disc 50 indicated by W2. Spring members 52a and 52b are attached to both ends of the cam groove 32 so as to be disposed between the respective bottom of the cam groove 32 and the cam pin 54. The first slider 30 further has on its right side in FIG Fig. 1 a guide 34, by means of which it is guided at its right end or door hinge facing end substantially horizontally displaceable.

Der erste Schieber 30 befindet sich zunächst in der rechts dargestellten Ausgangslage A1. Dabei befindet sich die Sperrriegeleinheit 10 noch nicht im Eingriff mit dem am Türrahmen angeordneten Bolzen 20. Der Türhebel mit der Scheibe 50 befindet sich hierbei in einer Ausgangsdrehlage WA. Durch ein Verdrehen des Türhebels mit der mit ihm gekoppelten Scheibe 50, hier gegen den Uhrzeigersinn, stößt der an der Scheibe 50 angebrachte Mitnehmerzapfen 54 in der Mitnehmernut 32 gegen das Federelement 52a, und es wird eine Kraft auf das Federelement 52a appliziert, die über das Federelement 52a auf den ersten Schieber 30 wirkt. Ist die Kraft bei einem weiteren Verdrehen des Türhebels mit der Scheibe 50 ausreichend groß, wird der erste Schieber 30 in eine erste Richtung R1 (in Fig. 1 im Wesentlichen nach links) verschoben. Dabei führt die Sperrriegeleinheit 10 durch Drehen eine Verriegelungsbewegung aus. Eine Verdrehung des Türhebels mit der Scheibe 50 um den Drehwinkel α1 entspricht hier einem Verfahren des ersten Schiebers 30 bis zu seiner Endlage E1. Die Sperrriegeleinheit 10 befindet sich in dieser Stellung des ersten Schiebers 30 im Eingriff mit dem Bolzen 20 des Türrahmens. Bei einer weiteren Verdrehung des Türhebels steht der erste Schieber 30 in seiner Endlage E1, und es wird das Federelement 52a durch den Mitnehmerzapfen 54 zusammengedrückt, was es ermöglicht, dass der Türhebel die Scheibe 50 um einen Drehwinkel α2 weiter in die gleiche Richtung verdreht, wenn sich der erste Schieber 30 in seiner Endlage E1 befindet. Wird die Scheibe 50 durch den Türhebel zurückgedreht, wird das Federelement 52a entspannt. Bei einem weiteren Drehen kommt dann der Mitnehmerzapfen 54 in Berührung mit dem an der anderen Seite der Mitnehmernut 32 angebrachten Federelement 52b, und der erste Schieber 30 wird dann in entsprechender Weise im Wesentlichen nach rechts verschoben, d.h. entgegen der Pfeilrichtung R1. Bei dem Vorgang bleibt das rechte Ende des ersten Schiebers 30 von der Führung 34 im Wesentlichen horizontal geführt, um eine Abstützung für die Betätigung der Sperrriegeleinheit 10 zu bilden.The first slider 30 is initially in the starting position A1 shown on the right. In this case, the locking bar unit 10 is not yet engaged with the bolt 20 arranged on the door frame. The door lever with the disk 50 is here in an output rotational position WA. By turning the door lever with the coupled thereto disc 50, here counterclockwise, the attached to the disc 50 driving pin 54 abuts in the cam groove 32 against the spring element 52a, and it is applied to the spring element 52a, which is applied via the Spring element 52a acts on the first slide 30. If the force with a further rotation of the door lever with the disc 50 is sufficiently large, the first slider 30 in a first direction R1 (in Fig. 1 essentially to the left). In this case, the locking bar unit 10 performs by turning a locking movement. A rotation of the door lever with the disc 50 by the rotation angle α1 corresponds to a method of the first slider 30 to its end position E1 here. The locking bar unit 10 is in this position of the first slider 30 in engagement with the bolt 20 of the door frame. Upon further rotation of the door lever, the first slider 30 is in its end position E1, and it is the spring element 52a compressed by the driving pin 54, which allows the door lever, the disk 50 by a rotational angle α2 further rotated in the same direction, if the first slider 30 is in its end position E1. If the disc 50 is rotated back by the door lever, the spring element 52a is relaxed. In a further rotation, then the driving pin 54 comes into contact with the mounted on the other side of the cam groove 32 spring element 52b, and the first slider 30 is then moved in a corresponding manner substantially to the right, ie opposite to the direction of the arrow R1. In the process, the right end of the first slider 30 remains substantially horizontally guided by the guide 34 to form a support for the operation of the lock bar unit 10.

Ein zweiter verschiebbarer Schieber 40 ist bei diesem Ausführungsbeispiel in einer Ebene vor dem ersten Schieber 30, und vorzugsweise parallel zum ersten Schieber 30 angeordnet. Der zweite Schieber 40 weist ebenfalls eine Mitnehmernut 42 auf. Für den zweiten Schieber 40 ist entsprechend wie für den ersten Schieber 30 eine Endlage E2 angegeben. Ferner ist für den zweiten Schieber 40 eine Zwischenlage Z2 dargestellt. An der Endlage E2 des zweiten Schiebers 40 ist ein Endschalter 60 oder dergleichen angebracht, der von dem zweiten Schieber 40 durch seine Bewegung zwischen der Zwischenstellung Z2 und der Endlage E2 betätigt wird.A second displaceable slider 40 is arranged in this embodiment in a plane in front of the first slider 30, and preferably parallel to the first slider 30. The second slider 40 also has a cam groove 42. For the second slider 40, an end position E2 is correspondingly indicated as for the first slider 30. Furthermore, an intermediate layer Z2 is shown for the second slider 40. At the end position E2 of the second slider 40, a limit switch 60 or the like is mounted, which is actuated by the second slider 40 by its movement between the intermediate position Z2 and the end position E2.

Entsprechend der Verdrehung des Türhebels mit der Scheibe 50 in Fig. 2 im Uhrzeigersinn wird der zweite Schieber 40 durch einen zweiten, an der Scheibe 50 fest angeordneten Mitnehmerzapfen 56, der in der Mitnehmernut 42 geführt ist, mitbewegt, wenn der Mitnehmerzapfen 56 gegen ein Ende der Mitnehmernut 42 anstößt und dann in der gleichen Richtung weiter bewegt wird. Da der erste Schieber 30 seine Endlage E1 schon einnimmt, wenn der Mitnehmerzapfen 54 gegen das Federelement 52a, jedoch nicht gegen das linke Ende (in Fig. 2) der Mitnehmernut 32 drückt, kann der Türhebel mit der Scheibe 50 aus der ersten Winkelstellung α1, bei der die Tür verriegelt ist, noch weiter um einen Winkel α2 verdreht werden. Bei dieser weiteren Verdrehung erfolgt ein Zusammendrücken des Federelementes 52a zwischen dem ersten Schieber 30 und dem Mitnehmerzapfen 54, und der zweite Schieber 40 wird aus seiner Zwischenlage Z2 in seine Endlage E2 bewegt, d.h. in Richtung des Pfeiles R2. Dabei wird der Endschalter 60 betätigt. Für eine Bestimmtheit ist der zweite Schieber 40 an einer Stelle mit einer Führung 44 linear geführt.According to the rotation of the door lever with the disc 50 in Fig. 2 in the clockwise direction, the second slider 40 is moved by a second, fixed to the disc 50 driving pin 56 which is guided in the cam groove 42, when the driving pin 56 abuts against one end of the cam groove 42 and is then moved in the same direction , Since the first slide 30 already occupies its end position E1 when the driving pin 54 against the spring element 52a, but not against the left end (in Fig. 2 ) of the cam groove 32 presses, the door lever with the disc 50 from the first angular position α1, wherein the door is locked, can be further rotated by an angle α2. In this further rotation, the spring element 52a is compressed between the first slider 30 and the driver pin 54, and the second slider 40 is moved out of its intermediate layer Z2 into its end position E2, ie in the direction of the arrow R2. In this case, the limit switch 60 is actuated. For a certainty, the second slider 40 is linearly guided at one location with a guide 44.

Durch diese erfindungsgemäße Anordnung wird gemäß dem Ausführungsbeispiel mittels des Endschalters 60 eine nicht weiter gezeigte aufpumpbare Türdichtung aktiviert, die dann die Türe gegenüber der Zarge im verschlossenen Zustand abdichtet. Dieses Abdichten kann sinnvoll erst erfolgen, wenn die Türe verschlossen und gesperrt ist. Umgekehrt wird beim Zurückdrehen der Scheibe 50 durch den Türhebel der Endschalter 60 wieder deaktiviert werden und der Druck aus der Türdichtung abgelassen werden, bevor die Sperrriegeleinheit 10 gegenüber dem Bolzen 20 entriegelt wird. Dadurch wird verhindert, dass die Türe bei aufgeblasener Türdichtung geöffnet wird, was zu einer Beschädigung der Dichtungen führen kann.As a result of this arrangement according to the invention, an inflatable door seal (not shown further) is activated by means of the limit switch 60, which then seals the door against the frame in the closed state. This sealing can make sense only when the door is closed and locked. Conversely, when the disc 50 is turned back by the door lever, the limit switch 60 is deactivated again and the pressure is released from the door seal before the locking bar unit 10 is unlocked relative to the pin 20. This prevents the door from being opened when the door seal is inflated, which can damage the seals.

Nunmehr wird der Vollständigkeit halber Bezug genommen auf die Figuren 3 und 4.Now, for the sake of completeness, reference will be made to FIGS Figures 3 and 4 ,

Figur 3 zeigt eine Ansicht auf die Scheibe 35 gemäß Fig. 1 mit dem dahinter befindlichen Schieber 30. Das im Schieber 30 befindliche Langloch ist zur Verdeutlichung voll ausgezeichnet dargestellt, obgleich es bei der Ansicht nach Fig. 3 durch die Scheibe 35 abgedeckt ist. In der Scheibe 35, die drehbeweglich gegenüber dem Vierkant 51 angeordnet ist, befindet sich die bogenförmige Nut 32 mit den Federeinrichtungen 52a und 52b. In diese bogenförmige Nut greift der Mitnehmerzapfen 54 ein. Ein Mitnehmerzapfen 154 ist in Fig. 3 entsprechend Fig. 1 einmal in der Schließstellung (Referenznummer 154) und einmal in der Offenstellung (Referenznummer 154') dargestellt. Damit der Riegel 30 eine Schiebebewegung, d.h. eine Bewegung in Horizontalrichtung, durchführen kann, bei Drehung der Scheibe 35 mit dem Mitnehmerzapfen 154, ist in dem Schieber 30 ein vorzugsweise schräg zur Vertikalen liegendes Langloch 36 ausgebildet, welches in Fig. 3 für die geschlossene Stellung mit 36 und für die offene Stellung mit 36' bezeichnet ist. Der Mitnehmerzapfen 54 ist durch die Federeinrichtungen 52a, 52b gegenüber der Scheibe 35 verlagerbar. FIG. 3 shows a view of the disc 35 according to Fig. 1 with the slider 30 located behind it. The slot 30 located in the slide 30 is shown in full detail for clarity, although it is in the view of Fig. 3 is covered by the disc 35. In the disc 35, which is arranged rotatably relative to the square 51, is the arcuate groove 32 with the spring means 52 a and 52 b. In this arcuate groove of the driving pin 54 engages. A driving pin 154 is in Fig. 3 corresponding Fig. 1 once in the closed position (reference number 154) and once in the open position (reference number 154 '). So that the bolt 30 can perform a sliding movement, ie a movement in the horizontal direction, upon rotation of the disk 35 with the driving pin 154, a preferably obliquely to the vertical longitudinal slot 36 is formed in the slider 30, which in Fig. 3 for the closed position 36 and for the open position with 36 'is designated. The driving pin 54 is displaceable by the spring devices 52a, 52b with respect to the disk 35.

Die mit 50 bezeichnete Scheibe ist drehfest auf dem Vierkant 51 angeordnet und trägt den Mitnehmerzapfen 56 (Fig. 2), welcher in den Schieber 40 eingreift, wie dies aus Fig. 2 erkennbar ist.The designated 50 disc is rotatably mounted on the square 51 and carries the driving pin 56 ( Fig. 2 ), which engages in the slider 40, as shown Fig. 2 is recognizable.

Die Schieber 30, 40 sind in Horizontalrichtung durch in den Zeichnungen nicht weiter bezeichnete Führungseinrichtungen verlagerbar gelagert. Der Schieber 30 ist weiterhin über einen Mitnehmerzapfen 62 mit der Sperrriegeleinheit 10 gekoppelt, wobei in Fig. 3 die Schließstellung durch das Bezugszeichen 62 und die Offenstellung durch das Bezugzeichen 62' dargestellt ist. Zugleich geben diese Positionen den Hub des Schiebers 30 wieder. Entsprechendes gilt für die Bewegung des Mitnehmerzapfens 154.The slides 30, 40 are mounted displaceably in the horizontal direction by guide means not further described in the drawings. The slider 30 is further coupled via a driving pin 62 with the locking bar unit 10, wherein in Fig. 3 the closed position by the reference numeral 62 and the open position by the reference numeral 62 'is shown. At the same time, these positions reflect the stroke of the slide 30. The same applies to the movement of the driving pin 154.

Figur 4 zeigt eine Draufsicht auf das Riegelwerk und verdeutlicht die Anordnung des Schiebers 30, der Steuerscheibe 35, der Steuerscheibe 50 und des weiteren Schiebers 40 in ihrer Lage relativ zu einander, wobei die Scheibe 50 fest auf dem Vierkant 51 angeordnet ist und mit diesem drehfähig ist, während die Scheibe 35 gegenüber dem Vierkant 51 drehfähig vorgesehen ist, um die vorstehend beschriebene Funktion auszuführen. FIG. 4 shows a plan view of the bolt mechanism and illustrates the arrangement of the slider 30, the control disk 35, the control disk 50 and the other slider 40 in position relative to each other, the disc 50 is fixedly mounted on the square 51 and is rotatable with this, while the disc 35 is provided rotatable relative to the square 51 to perform the function described above.

Obwohl die vorliegende Erfindung anhand bevorzugter Ausführungsbeispiele vorliegend beschrieben wurde, ist sie darauf nicht beschränkt, sondern auf vielfältige Weise modifizierbar.Although the present invention has been described in terms of preferred embodiments herein, it is not limited thereto, but modifiable in a variety of ways.
