Description

Die Erfindung betrifft eine Personenschleuse gemäß Oberbegriff des Anspruchs 1.The invention relates to a security gate according to the preamble of claim 1.

Personenschleusen in Form von Karusselltüren oder Drehkreuzen dienen der zyklischen Freigabe eines Durchgangs, wobei den Durchgang sperrende Sperrelemente innerhalb von den Durchgang begrenzenden Leitelementen beweglich sind. Die Sperrelemente sind beispielsweise die Türflügel einer Karusselltür oder die Sperrholme eines Drehkreuzes. Zum Blockieren der Bewegung des Trägerelements, und somit zum Sperren des Durchgangs, ist eine Verriegelungseinrichtung vorgesehen, deren Riegel zwischen einer Verriegelungsstellung und einer Freigabestellung beweglich sind. In der Verriegelungsstellung liegt ein Riegel an einer Wirkfläche des Trägerelements an und hemmt so dessen Bewegung. Dabei weist das Trägerelement mindestens eine erste und eine zweite Wirkfläche auf, die in entgegengesetzte Bewegungsrichtungen weisen, wodurch die Bewegung des Trägerelements in beide Bewegungsrichtungen blockiert werden kann. Zu diesem Zweck weist die Verriegelungseinrichtung in der Regel zwei Riegel auf, von denen ein erster in seiner Verriegelungsstellung an einer der ersten Wirkflächen, ein zweiter an einer der zweiten, in entgegengesetzte Richtung weisenden Wirkflächen anliegt. Entgegengesetzt ist hier so zu verstehen, dass durch die Riegel eine Bewegung des Trägerelements in entgegengesetzten Richtungen blockiert werden kann. Hierzu müssen die Flächennormalen auf den ersten und zweiten Wirkflächen nicht notwendigerweise einen Winkel von exakt 180° einschließen.Personal locks in the form of revolving doors or turnstiles are used for the cyclic release of a passage, wherein the passage-blocking elements are movable within the passage-limiting guide elements. The locking elements are for example the door of a revolving door or the piles of a turnstile. To block the movement of the carrier element, and thus to block the passage, a locking device is provided, the latch between a locking position and a release position are movable. In the locking position, a latch abuts an active surface of the carrier element and thus inhibits its movement. In this case, the carrier element has at least one first and one second active surface, which point in opposite directions of movement, whereby the movement of the carrier element in both directions of movement can be blocked. For this purpose, the locking device usually has two bars, of which a first in its locking position on one of the first active surfaces, a second rests on one of the second, pointing in opposite directions active surfaces. Opposite is here to be understood that by the bolt movement of the support member can be blocked in opposite directions. For this purpose, the surface normals on the first and second active surfaces need not necessarily include an angle of exactly 180 °.

In einer der möglichen Betriebsarten werden die Riegel gegen eine Rückstellkraft aktiv in der Freigabestellung gehalten, beispielsweise durch die Kraft eines Elektromagneten. Ein Abschalten des Elektromagneten führt dann zum Einfallen der Riegel in die Verriegelungsstellung. Wenn beide Riegel gleichzeitig in ihre Verriegelungsstellung einfallen, besteht die Gefahr, dass eine Person in der Personenschleuse eingeschlossen wird und sich, beispielsweise bei einem Stromausfall, selbst nicht mehr befreien kann. Um dieser Gefahr zu begegnen, wurde bereits in der DE 40 07 303 C2 eine Sicherheitspersonenschleuse vorgeschlagen, bei der die Wirkflächen an radial von einer Drehachse abstehenden Nocken angeordnet sind. Die Riegel weisen einen solchen Abstand zueinander auf, dass ihre in der Verriegelungsstellung an den Wirkflächen in Anlage kommenden Anlageflächen in bezug auf die Drehachse einen größeren Winkelabstand aufweisen als die Wirkflächen. Dadurch wird verhindert, dass beide Riegel gleichzeitig in ihre Verriegelungsstellung einfallen können. Allerdings ist die Konstruktion recht aufwendig, und eine Nachrüstung einer herkömmlichen Personenschleuse, wie eingangs beschrieben, ist bei diesem System nicht möglich. Umgekehrt ist es nicht ohne weiteres möglich, die Konstruktion so zu ändern, dass eine gleichzeitige Blockade in beide Richtungen möglich ist, falls dies gewünscht wird.In one of the possible modes of operation, the bolts are actively held against a restoring force in the release position, for example by the Force of an electromagnet. A switching off of the electromagnet then leads to the collapse of the latch in the locked position. If both bars simultaneously come into their locking position, there is a risk that a person is trapped in the security gate and, for example, in a power outage, can not free themselves. To counter this danger, was already in the DE 40 07 303 C2 a security person sluice proposed in which the active surfaces are arranged on radially projecting from a rotation axis cams. The bars have such a distance from each other that their in the locking position on the active surfaces in abutment bearing surfaces with respect to the axis of rotation have a greater angular distance than the active surfaces. This prevents both bars from being able to enter their locking position at the same time. However, the construction is quite expensive, and retrofitting a conventional personal lock, as described above, is not possible with this system. Conversely, it is not readily possible to change the design to allow simultaneous blockage in both directions, if desired.

Es ist daher Aufgabe der Erfindung, eine Personenschleuse der eingangs genannten Art derart weiterzubilden, dass bei Bedarf das Einschließen einer Person verhindert werden kann.It is therefore an object of the invention to develop a personal lock of the type mentioned in such a way that, if necessary, the inclusion of a person can be prevented.

Die Aufgabe wird erfindungsgemäß durch eine Personenschleuse mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche.The object is achieved by a person lock with the features of claim 1. Advantageous developments are the subject of the dependent claims.

Der Erfindung liegt der Gedanke zugrunde, dass mittels des am Trägerelement beweglich angeordneten Steuerelements das gleichzeitige Einfallen beider Riegel in die Verriegelungsstellung zumindest in bestimmten Positionen der Personenschleuse verhindert wird. Dadurch kann verhindert werden, dass Personen in der Personenschleuse eingeschlossen werden und sich nicht zumindest in eine Richtung befreien können. Zudem ist es möglich, zunächst ohne das Steuerelement betriebene Personenschleusen durch Montage des Steuerelements am Trägerelement nachzurüsten. Schließlich kann durch einfaches Entfernen des Steuerelements die Personenschleuse so umgebaut werden, dass auch eine kontrollierte, beispielsweise manuell gesteuerte Blockade in beiden Richtungen gleichzeitig möglich ist. Die erfindungsgemäße Personenschleuse ist somit nach dem Baukastenprinzip aufgebaut.The invention is based on the idea that by means of the carrier element movably arranged control the simultaneous collapse of both bars is prevented in the locked position, at least in certain positions of the security gate. This can be prevented that people are trapped in the lock and can not free themselves in one direction at least. In addition, it is possible initially to retrofit without the control operated person locks by mounting the control on the support element. Finally, by simply removing the control, the personal lock can be rebuilt so that a controlled, for example manually controlled blockade in both directions is possible at the same time. The personal lock according to the invention is thus constructed on the modular principle.

Es wird bevorzugt, dass das Trägerelement und das Steuerelement um eine gemeinsame Drehachse drehbar gelagert sind. Dadurch wird der Tatsache Rechnung getragen, dass bei den meisten Personenschleusen die Sperrelemente auf einer zyklischen Bahn umlaufen, was am einfachsten durch eine Drehbewegung des Trägerelements verwirklicht wird. Dabei weist das Trägerelement zweckmäßig mindestens einen radial abstehenden, eine erste und eine zweite Wirkfläche aufweisenden Verriegelungsnocken auf, während das Steuerelement mindestens einen radial abstehenden, eine erste und eine zweite Steuerfläche aufweisenden Steuernocken aufweist.It is preferred that the carrier element and the control element are rotatably mounted about a common axis of rotation. This takes into account the fact that in most passenger locks the locking elements rotate on a cyclic path, which is most easily realized by a rotational movement of the support member. In this case, the support element expediently has at least one radially projecting, a first and a second active surface having locking cam, while the control element has at least one radially projecting, a first and a second control surface having control cam.

Prinzipiell ist es möglich, dass die Personenschleuse ein Getriebe zur Übertragung der Bewegung des Trägerelements auf die Sperrelemente aufweist. Dadurch ist es einerseits möglich, beispielsweise eine Linearbewegung des Trägerelements in eine Bewegung der Sperrelemente auf einer geschlossenen umlaufenden Bahn umzuwandeln. Andererseits ist es auch möglich, die Bewegung des Trägerelements mit einer Übersetzung auf die Sperrelemente zu übertragen, so dass beispielsweise ein voller Umlauf der Sperrelemente durch mehrere Umdrehungen des Trägerelements erreicht wird. Ein einfacherer Aufbau ergibt sich aber, wenn die Sperrelemente fest mit dem Trägerelement verbunden sind, so dass eine Umdrehung des Trägerelements um 360° in einen vollständigen Umlauf der Sperrelemente in den Leitelementen umgesetzt wird. Dabei wird bevorzugt, dass sich die Sperrelemente in gleichen Winkelabständen zueinander in radialer Richtung vom Trägerelement erstrecken. Desweiteren wird bevorzugt, dass das Trägerelement mit mehreren Verriegelungsnocken versehen ist, die in gleichen Winkelabständen zueinander vom Trägerelement abstehen.In principle, it is possible for the personal lock to have a gear for transmitting the movement of the carrier element to the blocking elements. This makes it possible, on the one hand, for example, to convert a linear movement of the carrier element into a movement of the blocking elements on a closed circulating path. On the other hand, it is also possible to transmit the movement of the carrier element with a translation to the blocking elements, so that, for example, a full circulation of the blocking elements is achieved by a plurality of revolutions of the carrier element. However, a simpler structure results when the blocking elements are firmly connected to the carrier element, so that a rotation of the carrier element by 360 ° in a complete circulation of the blocking elements in the guide elements is implemented. It is preferred that the blocking elements extend at equal angular distances from one another in the radial direction from the carrier element. Furthermore, it is preferred that the carrier element is provided with a plurality of locking cams which protrude from the carrier element at equal angular distances from one another.

Zweckmäßig weisen die Riegel jeweils eine Anlagefläche auf, die in der Verriegelungsstellung an einer der Wirkflächen und einer der Steuerflächen anliegt. Dabei sind prinzipiell zwei Varianten denkbar. Zum einen können die Riegel einen solchen Abstand zueinander aufweisen, dass ihre Anlageflächen in der Verriegelungsstellung in bezug auf die Drehachse einen Winkelabstand aufweisen, der dem Winkelabstand einer ersten Wirkfläche eines der Verriegelungsnocken und einer zweiten Wirkfläche eines anderen Verriegelungsnockens entspricht. Die Riegel sind dann so angeordnet, dass sie stets mit zwei unterschiedlichen Verriegelungsnocken zusammenwirken. Zum anderen können die Riegel einen solchen Abstand zueinander aufweisen, dass ihre Anlageflächen in der Verriegelungsstellung in bezug auf die Drehachse einen Winkelabstand aufweisen, der dem Winkelabstand der ersten und der zweiten Wirkfläche desselben Verriegelungsnockens entspricht. In diesem Fall wirken beide Riegel stets auf denselben Verriegelungsnocken.Expediently, the bolts each have a contact surface, which abuts in the locking position on one of the active surfaces and one of the control surfaces. In principle, two variants are conceivable. On the one hand, the bars may have such a distance from each other that their contact surfaces in the locking position with respect to the axis of rotation have an angular distance corresponding to the angular distance of a first active surface of the locking cam and a second active surface of another locking cam. The bars are then arranged so that they always interact with two different locking cam. On the other hand, the bars may have such a distance from each other that their contact surfaces in the locking position with respect to the axis of rotation have an angular distance corresponding to the angular distance of the first and the second effective surface of the same locking cam. In this case, both bars always act on the same locking cam.

Gemäß einer ersten vorteilhaften Ausführungsform ist das Steuerelement mit einer der Anzahl der Verriegelungsnocken entsprechenden Anzahl von Steuernocken versehen, die in gleichen Winkelabständen zueinander vom Steuerelement abstehen. Dadurch wird erreicht, dass in keinem Fall die Drehung des Trägerelements in beiden Richtungen blockiert werden kann. Gemäß einer alternativen Ausführungsform ist das Steuerelement mit einer der halben Anzahl der Verriegelungsnocken entsprechenden Anzahl von Steuernocken versehen, die in gleichen Winkelabständen zueinander vom Steuerelement abstehen. In diesem Fall gibt es sowohl Positionen, in denen die die Drehung des Trägerelements gleichzeitig in beiden Richtungen gesperrt werden kann, als auch Positionen, in denen jeweils nur die Sperrung in einer Drehrichtung möglich ist.According to a first advantageous embodiment, the control element is provided with a number of locking cams corresponding number of control cam, which protrude at equal angular distances from each other from the control. This ensures that in no case the rotation of the support member can be blocked in both directions. According to an alternative embodiment, the control element is provided with a number of control cams corresponding to half the number of locking cams, which protrude from the control at equal angular distances from one another. In this case, there are both positions in which the the rotation of the support member can be locked simultaneously in both directions, as well as positions in which only the blocking in one direction of rotation is possible.

Zweckmäßig ist das Steuerelement bezüglich des Trägerelements gegen eine Rückstellkraft begrenzt verdrehbar. Dabei ist vorteilhaft jeder Steuernocken einem Verriegelungsnocken zugeordnet. Vorzugsweise ist jeder Steuernocken breiter als der zugehörige Verriegelungsnocken und überdeckt diesen.Suitably, the control element is limited in rotation with respect to the support member against a restoring force. In this case, each control cam is advantageously associated with a locking cam. Preferably, each control cam is wider than the associated locking cam and covers it.

Die in Fig. 1 gezeigte Sperrmechanik 10 für eine Personenschleuse weist ein um eine Drehachse 12 drehbares Trägerelement 14 in Form einer Scheibe auf, von dem in radialer Richtung in konstanten Winkelabständen zueinander sechs Verriegelungsnocken 16 abstehen. Jeder der Verriegelungsnocken 16 weist eine in Richtung des Uhrzeigersinns weisende erste Wirkfläche 18 und eine in Richtung entgegen des Uhrzeigersinns weisende zweite Wirkfläche 20 auf. Die Drehbewegung des Trägerelements 14 ist mit einer Bewegung der Sperrelemente der Personenschleuse direkt gekoppelt, so dass eine Blockade des Trägerelements 14 eine Blockade der Bewegung der Sperrelemente bewirkt. Um die Bewegung des Trägerelements 14 blockieren zu können, sind ein erster Riegel 22 und ein zweiter Riegel 24 vorgesehen, die jeweils eine Anlagefläche 26 aufweisen. Jeder der Riegel 22, 24 ist zwischen einer Verriegelungsstellung und einer Freigabestellung verschwenkbar. In der Freigabestellung, wie sie für beide Riegel 22, 24 in Fig. 1 gezeigt ist, hemmt der betreffende Riegel die Drehung des Trägerelements 14 nicht. In seiner Verriegelungsstellung blockiert der betreffende Riegel 22, 24 eine Drehung des Trägerelements 14, indem beispielsweise die Anlagefläche 26 des ersten Riegels 22 an einer der ersten Wirkflächen 18 in Anlage kommt oder die Anlagefläche 26 des zweiten Riegels 24 an einer der zweiten Wirkflächen 20. Auf jeden der Riegel 22, 24 wirkt eine Feder 28, deren Federkraft dazu bestimmt ist, die Riegel 22, 24 in ihre Freigabestellung zu bewegen. Eine Bewegung in die Verriegelungsstellung erfolgt mittels Elektromagneten 30, deren Kraft bei Betätigung die Federkraft überwindet.In the Fig. 1 Locking mechanism 10 shown for a personal lock has a rotatable about an axis of rotation 12 support member 14 in the form of a disc, from the six radial locking cam 16 protrude in the radial direction at constant angular intervals. Each of the locking cams 16 has a first active surface 18 pointing in the direction of the clockwise direction and a second active surface 20 pointing in the direction of the counterclockwise direction. The rotational movement of the carrier element 14 is directly coupled to a movement of the locking elements of the personal lock, so that a blockage of the carrier element 14 is a blockade of the movement causes the locking elements. In order to be able to block the movement of the carrier element 14, a first latch 22 and a second latch 24 are provided, each having a contact surface 26. Each of the latches 22, 24 is pivotable between a locking position and a release position. In the release position, as shown for both bars 22, 24 in Fig. 1 is shown, the relevant bar does not inhibit the rotation of the support member 14. In its locking position of the relevant latch 22, 24 blocks rotation of the support member 14, for example, the contact surface 26 of the first latch 22 on one of the first active surfaces 18 comes into abutment or the contact surface 26 of the second latch 24 on one of the second active surfaces 20th Auf Each of the latches 22, 24 is acted upon by a spring 28 whose spring force is intended to move the latches 22, 24 into their release position. A movement in the locking position by means of electromagnet 30 whose force overcomes the spring force when actuated.

Am Trägerelement 14 ist ein Steuerelement in Form einer Steuerscheibe 32 angeordnet, welche ebenfalls um die Drehachse 12 drehbar ist und zudem gegenüber dem Trägerelement 14 begrenzt verdrehbar ist. Von der Steuerscheibe 32 stehen in radialer Richtung in konstanten Winkelabständen zueinander drei Steuernocken 34 ab, die breiter sind als die Verriegelungsnocken 16. Jeder der Steuernocken 34 weist eine in Richtung des Uhrzeigersinns weisende erste Steuerfläche 36 und eine in Richtung entgegen des Uhrzeigersinns weisende zweite Steuerfläche 38 auf. Die Steuernocken 34 sind jeden zweiten Verriegelungsnocken 16 überdeckend angeordnet, wobei sie mit ihren Steuerflächen 36, 38 über die Wirkflächen 18, 20 dieser Verriegelungsnocken 16 überstehen. Gegen die Kraft zweier Rückstellfedern 40 kann die Steuerscheibe 32 gegenüber dem Trägerelement 14 in beiden Drehrichtungen etwas weiter verdreht werden, als bis entweder die ersten Steuerflächen 36 mit den ersten Wirkflächen 18 oder die zweiten Steuerflächen 38 mit den zweiten Wirkflächen 20 fluchten. Die beiden Riegel 22, 24 sind in einem solchen Abstand zueinander angeordnet, dass ihre Anlageflächen 26 in der Verriegelungsstellung in bezug auf die Drehachse 12 einen Winkelabstand aufweisen, der dem Winkelabstand der ersten Wirkfläche 18 eines der Verriegelungsnocken 16 und der zweiten Wirkfläche 20 des übernächsten Verriegelungsnockens 16 entspricht oder etwas größer ist.On the support member 14, a control in the form of a control disk 32 is arranged, which is also rotatable about the axis of rotation 12 and also limited relative to the support member 14 is rotatable. Each of the control cam 34 has a pointing in the clockwise direction first control surface 36 and a pointing in the counterclockwise direction second control surface 38th From the control disk 32 are in the radial direction at constant angular intervals from each other three control cam 34 from on. The control cam 34 are arranged overlapping each second locking cam 16, wherein they survive with their control surfaces 36, 38 on the active surfaces 18, 20 of the locking cam 16. Against the force of two return springs 40, the control disk 32 can be rotated slightly further in two directions of rotation relative to the carrier element 14, until either the first control surfaces 36 are aligned with the first active surfaces 18 or the second control surfaces 38 with the second active surfaces 20. The two bars 22, 24 are arranged at such a distance from each other that their contact surfaces 26 in the locking position with respect to the axis of rotation 12 have an angular distance corresponding to the angular distance of the first active surface 18 of the locking cam 16 and the second active surface 20 of the next locking cam 16 or slightly larger ,

In Fig. 2a bis 2d ist die Funktionsweise eines mit der Sperrmechanik 10 gemäß Fig. 1 ausgestatteten Drehkreuzes 50 veranschaulicht. Das Drehkreuz 50 weist drei Sperrholme 52 auf, die fest mit dem Trägerelement 14 verbunden sind und sich, ausgehend von den Verriegelungsnocken 16, die nicht von einem Steuernocken 34 überdeckt werden, in radialer Richtung von der Drehachse 12 weg erstrecken. Die Sperrholme 52 bewegen sich innerhalb von Leitelementen 54, wobei in dem in Fig. 2a bis 2d dargestellten rechten Bereich ein Durchgangsbereich 56 gebildet ist. Der linke Bereich wird durch Begrenzungselemente 58 abgesperrt, zwischen denen die Sperrholme 52 hindurchbewegt werden können. In der in Fig. 2a gezeigten Stellung ragt lediglich einer der Sperrholme 52 in den Durchgangsbereich 56 und versperrt diesen. Die beiden Riegel 22, 24 liegen an den Wirkflächen 18, 20 zweier Verriegelungsnocken 16 an, die nicht durch Steuernocken 34 überdeckt werden. Eine Drehung des Trägerelements 14, und damit eine Bewegung der Sperrholme 52, ist dadurch blockiert. Eine Person, die sich im Durchgangsbereich 56 befindet, kann das Drehkreuz 50 jedoch entweder auf der einen oder auf der anderen Seite verlassen.In Fig. 2a to 2d is the operation of one with the locking mechanism 10 according to Fig. 1 equipped turnstile 50 illustrated. The turnstile 50 has three piles 52, which are fixedly connected to the carrier element 14 and, starting from the locking cam 16, which are not covered by a control cam 34, extending in the radial direction of the rotation axis 12 away. The piles 52 move within vanes 54, wherein in the in Fig. 2a to 2d shown right area a passage area 56 is formed. The left-hand area is blocked off by delimiting elements 58, between which the piling spars 52 can be moved. In the in Fig. 2a shown position projects only one of the piles 52 in the passage area 56 and blocks it. The two latches 22, 24 are located on the active surfaces 18, 20 of two locking cam 16, which are not covered by control cam 34. A rotation of the support member 14, and thus a movement of the piles 52, is thereby blocked. However, a person located in the passageway 56 may leave the turnstile 50 either on one side or on the other side.

Bei einer Freigabe des Durchgangs mittels Bewegung der Riegel 22, 24 in ihre Freigabestellung kann eine im Durchgangsbereich 56 befindliche Person die Sperrholme 52 in die in Fig. 2b gezeigte Position bewegen. In dieser Position ist der Durchgangsbereich 56 durch eines der Leitelemente 54 und zwei der Sperrholme 52 abgeschlossen, so dass die Person den Durchgangsbereich 56 nur dann verlassen kann, wenn sich die Sperrholme 52 weiterbewegen lassen. Hier kommt die Steuerscheibe 32 zur Anwendung: wie in Fig. 2b gezeigt, verhindern die über die Wirkflächen 18, 20 der Verriegelungsnocken 16 überstehenden Steuerflächen 36, 38 ein Einfallen der Riegel 22, 24 in die Verriegelungsposition.In a release of the passage by movement of the latch 22, 24 in its release position, a person located in the passage area 56, the piles 52 in the in Fig. 2b move the position shown. In this position, the passage area 56 is closed by one of the guide elements 54 and two of the locking bars 52, so that the person can leave the passage area 56 only when the piles 52 can be moved on. Here the control disk 32 is used: as in Fig. 2b shown, over the active surfaces 18, 20 of the locking cam 16 projecting control surfaces 36, 38 prevent a collapse of the latch 22, 24 in the locked position.

Eine Drehung im Uhrzeigersinn kann durch Bewegen des ersten Riegels 22 in seine Verriegelungsposition blockiert werden wie in Fig. 2c dargestellt. Der erste Riegel 22 kommt dabei jedoch auch an einer der ersten Steuerflächen 36 zur Anlage und bewirkt ein Verdrehen der Steuerscheibe 32 gegenüber dem Trägerelement 14 in eine erste Sicherungsposition. Ein Überstehen der zweiten Steuerflächen 38 über die zweiten Wirkflächen 20 verhindert dann eine Bewegung des zweiten Riegels 24 in seine Verriegelungsposition, so dass eine im Durchgangsbereich 56 eingeschlossene Person sich durch Drehen der Sperrholme 52 entgegen dem Uhrzeigersinn wieder befreien kann. Die umgekehrte Situation ist in Fig. 2d beschrieben. Hier sperrt der zweite Riegel 24 durch Anlage an eine der zweiten Wirkflächen 20 eine Drehung des Trägerelements 14 gegen den Uhrzeigersinn. Die Anlagefläche 26 des zweiten Riegels 24 liegt aber auch an einer der zweiten Steuerflächen 38 an, so dass die ersten Steuerflächen 36 über die ersten Wirkflächen 18 überstehen und eine Bewegung des ersten Riegels 22 in seine Verriegelungsposition verhindern. Die Steuerscheibe 32 befindet sich in einer zweiten Sicherungsposition, und eine im Durchgangsbereich 56 eingeschlossene Person kann sich dann durch Drehen der Sperrholme 52 im Uhrzeigersinn wieder befreien.Clockwise rotation can be blocked by moving the first latch 22 to its latched position as in FIG Fig. 2c shown. However, the first latch 22 also comes to one of the first control surfaces 36 to the plant and causes a rotation of the control disk 32 relative to the carrier element 14 in a first securing position. Exceeding the second control surfaces 38 via the second active surfaces 20 then prevents movement of the second latch 24 in its locking position, so that a trapped in the passageway area 56 person can be freed by turning the locking bars 52 counterclockwise again. The reverse situation is in Fig. 2d described. Here, the second latch 24 locks by engagement with one of the second active surfaces 20, a rotation of the support member 14 counterclockwise. However, the abutment surface 26 of the second bolt 24 also bears against one of the second control surfaces 38, so that the first control surfaces 36 project beyond the first active surfaces 18 and prevent movement of the first bolt 22 into its locking position. The control disk 32 is in a second securing position, and a trapped in the passage area 56 person can then free by turning the locking bars 52 clockwise again.

Fig. 3a bis 3c zeigt die Anwendung des Prinzips auf eine vierflügelige Karusselltür 60. Diese weist vier Türflügel 62 auf, die fest mit dem Trägerelement 14 verbunden sind, das in diesem Ausführungsbeispiel lediglich vier Verriegelungsnocken 16 aufweist. Die Türflügel 62 erstrecken sich von den Verriegelungsnocken 16 aus in radialer Richtung bezüglich der Drehachse 12. Eine Drehung des Trägerelements 14 bewirkt eine Bewegung der Türflügel 62 innerhalb von Leitelementen 64, wobei entgegen dem Ausführungsbeispiel gemäß Fig. 2a bis 2d kein Begrenzungselement vorgesehen ist. Somit weist die Karusselltür 60 zwei Durchgangsbereiche 66 auf. Diese Tatsache erfordert eine Anpassung der Konstruktion, da in beiden Durchgangsbereichen 66 Personen eingeschlossen werden können. So weist die Steuerscheibe 32 vier Steuernocken 34 auf, so dass jeder Verriegelungsnocken 16 von einem Steuernocken 34 überdeckt wird. Desweiteren entspricht der Winkelabstand der beiden Anlageflächen 26 in der Verriegelungsstellung dem Winkelabstand der ersten Wirkfläche 18 eines der Verriegelungsnocken 16 und der zweiten Wirkfläche 20 des nächsten Verriegelungsnockens 16. In Fig. 3a ist gezeigt, wie sich beide Riegel 22, 24 in der Freigabeposition befinden und von den Steuernocken 34 mit ihren über die Wirkflächen 18, 20 überstehenden Steuerflächen 36, 38 an einer Bewegung in die Verriegelungsposition gehindert werden. Fig. 3b zeigt eine Blockade der Drehbewegung im Uhrzeigersinn, die durch Anlage der Anlagefläche 26 des ersten Riegels 22 an einer der ersten Wirkflächen 18 bewirkt wird. Der zweite Riegel 24 wird durch einen der Steuernocken 34, dessen zweite Steuerfläche 38 über die zweite Wirkfläche 20 des betreffenden Verriegelungsnockens 16 übersteht, an einer Bewegung in die Verriegelungsposition gehindert, so dass in den Durchgangsbereichen 66 eingeschlossene Personen sich durch Drehen der Türflügel 62 entgegen dem Uhrzeigersinn befreien können. Dasselbe Prinzip findet in der Position gemäß Fig. 2c Anwendung. Hier sperrt der zweite Riegel 24 eine Drehung entgegen dem Uhrzeigersinn, während der erste Riegel 22 an einer Bewegung in seine Verriegelungsposition gehindert wird. In den Durchgangsbereichen 66 eingeschlossene Personen können sich durch Drehen der Türflügel 62 im Uhrzeigersinn befreien. In Fig. 3b befindet sich die Steuerscheibe 32 in der ersten, in Fig. 3c in der zweiten Sicherungsposition. Fig. 3a to 3c shows the application of the principle on a four-leaf revolving door 60. This has four door leaves 62 which are fixedly connected to the support member 14, which has only four locking cam 16 in this embodiment. The door wings 62 extend from the locking cams 16 in the radial direction with respect to the axis of rotation 12. A rotation of the support member 14 causes movement of the door wings 62 within vanes 64, wherein contrary to the embodiment according to Fig. 2a to 2d no limiting element is provided. Thus, the revolving door 60 has two passage areas 66. This fact requires an adaptation of the construction since 66 people can be trapped in both passage areas. Thus, the control disk 32 four control cam 34, so that each locking cam 16 is covered by a control cam 34. Furthermore, the angular spacing of the two contact surfaces 26 in the locking position corresponds to the angular distance of the first active surface 18 of one of the locking cams 16 and the second active surface 20 of the next locking cam 16 Fig. 3a It is shown how both bars 22, 24 are in the release position and are prevented by the control cam 34 with their over the active surfaces 18, 20 projecting control surfaces 36, 38 from moving into the locking position. Fig. 3b shows a blockade of the rotational movement in the clockwise direction, which is effected by abutment of the contact surface 26 of the first bolt 22 on one of the first active surfaces 18. The second latch 24 is prevented from moving to the locking position by one of the control cam 34, whose second control surface 38 projects beyond the second active surface 20 of the respective locking cam 16, so that people trapped in the passage regions 66 move against the door 62 by turning the door wings 62 Can liberate clockwise. The same principle applies in the position according to Fig. 2c Application. Here, the second latch 24 locks counterclockwise rotation while the first latch 22 is prevented from moving to its latching position. Persons trapped in the passage areas 66 can free themselves by turning the door leaves 62 in a clockwise direction. In Fig. 3b is the control disk 32 in the first, in Fig. 3c in the second backup position.
