Abstract

The position detection device uses a lever mechanism which is displaced against a spring return force by the lock bolt (12), for operation of a switch device, providing the lock bolt position signal. The lever mechanism is adjustable so that the switch device is operated in different displacement positions of the lever mechanism, by altering the relative geometric positions of the lever mechanism components.

Description

Die Erfindung betrifft eine Vorrichtung zum Erfassen der Stellung eines Schloßriegels, mit einer Hebeleinrichtung, welche an einer Kraftaufnahmestelle von dem Schloßriegel mit Kraft beaufschlagbar ist und damit entgegen einer Rückstellkraft bewegbar ist und einer Schalteinrichtung, welche von einer Kraftabgabestelle der Hebeleinrichtung betätigbar ist.The invention relates to a device for detecting the Position of a lock bolt, with a lever device, which at a force absorption point from the lock bolt can be acted upon with force and thus against a restoring force is movable and a switching device, which operable from a power output point of the lever device is.

Gattungsgemäße Riegelschaltkontakte sind bekannt. Sie dienen dem Erfassen der Stellung eines Schloßriegels. Durch das Ausschließen des Schloßriegels wird der Riegelschaltkontakt mit Kraft beaufschlagt, um im vollständig ausgeschlossenen Zustand eine Schalteinrichtung zu betätigen. Der voll ausgeschlossene Zustand entspricht dem maximal möglichen Riegelweg, welcher bei gängigen Schlössern 20 mm beträgt. Die Schalteinrichtung meldet dann den entsprechenden Status des voll ausgeschlossenen Schloßriegels etwa einer Einbruchmeldezentrale.Bolt switch contacts of the generic type are known. You serve the detection of the position of a lock bolt. By excluding the lock bolt becomes the bolt switch contact energized to be completely excluded State to actuate a switching device. The fully excluded state corresponds to the maximum possible bolt travel, which is 20 mm for common locks is. The switching device then reports the corresponding Status of the fully excluded lock bolt, for example a burglar alarm center.

Aus sicherheitstechnischen Gründen ist für die Funktion des Riegelschaltkontaktes entscheidend, daß die Betätigung der Schalteinrichtung und somit die Meldung an die Einbruchmelderzentrale tatsächlich erst im vollkommen ausgeschlossenen Zustand des Schloßriegels erfolgt. Anderenfalls würde bei vorzeitigem Auslösen der Meldung fälschlicherweise der Status einer vollständig abgeschlossenen Tür übermittelt. Diese Anforderung an das Alarmsystem ist in der Praxis problematisch. Im Allgemeinen liegt ein gewisser Abstand zwischen dem Türrahmen und somit dem Schließblech und dem das Schloß und den Schloßriegels tragenden Türblatt vor. Da dieser Abstand von der Konstruktion der Tür abhängt bzw. aufgrund baulicher Varianzen unterschiedlich sein kann, wird der Schloßriegel von Fall zu Fall in seinem vollständig ausgeschlossenen Zustand unterschiedlich weit in das Schließblech hineinragen. Dies muß bei der Montage des Riegelschaltkontaktes berücksichtigt werden, damit nicht, bei einem kleinen Abstand zwischen Türblatt und Türrahmen, die Schalteinrichtung vorzeitig betätigt wird oder, bei einem großen Abstand zwischen Türblatt und Türrahmen, ein Schalten der Schaltereinrichtung gänzlich ausbleibt.For safety reasons, the function of the Bolt switch contact crucial that the actuation of the Switching device and thus the message to the intrusion control panel actually only in the completely excluded The lock bolt is in condition. Otherwise, would the message was incorrectly triggered prematurely Status of a fully closed door transmitted. This requirement for the alarm system is problematic in practice. Generally there is a certain distance between the door frame and thus the striking plate and that Lock and the door leaf carrying the bolt. There this distance depends on the construction of the door or may vary due to structural variations, the lock bolt will be complete in its case by case excluded state to different degrees in that Protrude striking plate. This must be done when installing the Bolt switch contact are taken into account, so not with a small distance between the door leaf and door frame, the switching device is actuated prematurely or, at a large distance between the door leaf and door frame Switching the switch device is completely absent.

Gewöhnlich muß der Monteur demnach Maßnahmen ergreifen, um den Riegelschaltkontakt stets in derselben Position im Hinblick auf die vollständig ausgefahrene Stellung des Schloßriegels zu bringen. Dies wird herkömmlich durch das Anbringen von Unterlegteilen bzw. durch das Einfügen von Aussparungen, etwa durch Auffräsen oder Aufbohren, erreicht.Usually the fitter has to take measures to the bolt switch contact always in the same position with regard to the fully extended position of the lock bolt bring to. This is traditionally due to the attachment of washers or by inserting recesses, such as by milling or boring.

Durch diese handwerklichen Arbeiten erhöht sich der Aufwand beim Einbau des Riegelschaltkontaktes erheblich und gleichermaßen die Montagekosten. Ebenso ist die Gefahr eines ungenauen Einbaus vergleichsweise hoch.This manual work increases the effort when installing the bolt switch contact considerably and equally the assembly costs. So is the danger inaccurate installation is comparatively high.

Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile des Standes der Technik auszuräumen und insbesondere einen Riegelschaltkontakt zur Verfügung zu stellen, welcher ohne aufwendige Montagearbeiten kontinuierlich und individuell den vorliegenden Einbauverhältnissen der Tür angepaßt werden kann. The invention has for its object to overcome the disadvantages of the prior art and, in particular, to provide a bolt switch contact which can be continuously and individually adapted to the existing installation conditions of the door without expensive assembly work.

Diese Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the features of patent claim 1 solved.

Die Erfindung baut auf der gattungsgemäßen Vorrichtung dadurch auf, daß die Hebeleinrichtung in der Weise einstellbar ist, daß derselben Position der Kraftabgabestelle je nach Einstellung verschiedene Positionen der Kraftaufnahmestelle entsprechen. Durch diesen Umstand ist es möglich, den Riegelschaltkontakt ohne Unterlegteile bzw. Auffräsungen oder Aufbohrungen in das Schließblech einzubauen und gleichwohl zu gewährleisten, daß stets nur bei vollständig ausgeschlossenem Schloßriegel die Schalteinrichtung betätigt wird. Liegt beispielsweise die Situation vor, daß Türrahmen und Türblatt einen großen Abstand aufweisen, so sollte möglichst bald nach dem Eintreten des Schloßriegels in das Schließblech eine Betätigung der Schaltereinrichtung erfolgen, damit der nach dem Eintreten des Schloßriegels in das Schließblech noch verbleibende Schloßriegelweg zum Auslösen des Schaltervorganges ausreicht. In der Situation, daß ein geringer Abstand zwischen Türrahmen und Türblatt vorliegt, sollte der Schloßriegel bereits einen größeren Weg nach seinem Eintritt in das Schließblech zurückgelegt haben, bevor die Kraftabgabestelle die Schalteinrichtung betätigt. So wird sichergestellt, daß nicht bereits vor dem vollständigen Ausschließen des Schloßriegels die Schalteinrichtung betätigt wird und so eine Fehlmeldung erzeugt wird.The invention builds on the generic device on that the lever device adjustable in the way is that the same position of the power delivery point ever After setting different positions of the force absorption point correspond. This makes it possible the bolt switch contact without washers or millings or drill holes in the striking plate and nevertheless to ensure that always only when complete excluded lock bolt actuated the switching device becomes. For example, is the situation that Door frame and door leaf have a large distance, so should be as soon as possible after entering the lock bolt an actuation of the switch device in the striking plate take place so that after entering the lock bolt in the striking plate still has a lock bolt path for triggering of the switch operation is sufficient. In the situation that a small distance between the door frame and door leaf the lock bolt should already have a larger one Traveled away after entering the striking plate have the switching device before the power output point operated. This ensures that not before complete exclusion of the lock bolt the switching device is pressed and thus generates an error message becomes.

Bevorzugt umfaßt die Vorrichtung ein Gehäuse, dessen gegenüberliegende Seitenwände eine Achse tragen, wobei die Hebeleinrichtung auf der Achse gelagert ist. Der Riegelschaltkontakt liegt somit in einer kompakten Bauform vor, und die funktionellen Teile der Vorrichtung stehen in definierter und sicherer Verbindung mit dem Gehäuse. Preferably, the device comprises a housing, the opposite one Side walls bear an axis, the Lever device is mounted on the axis. The bolt switch contact is therefore available in a compact design, and the functional parts of the device are defined and secure connection to the housing.

Vorzugsweise erfolgt das Einstellen der Hebeleinrichtung durch Verändern der relativen geometrischen Lage von Hebelkomponenten. Dies ist eine besonders einfache Weise, die relativen Positionen von Kraftabgabestelle und Kraftaufnahmestelle je nach den vorliegenden Gegebenheiten zu variieren.The lever device is preferably adjusted by changing the relative geometrical position of lever components. This is a particularly simple way that relative positions of the power delivery point and the force take-up point vary depending on the circumstances.

Bevorzugt weist die Hebeleinrichtung zwei Arme auf, welche auf der Achse gelagert sind, wobei an dem ersten Arm die Kraftaufnahmestelle und an dem zweiten Arm die Kraftabgabestelle vorgesehen ist und das Einstellen der Hebeleinrichtung durch Verändern des Winkels zwischen den Armen erfolgt. Diese Konstruktion gestattet eine kompakte Bauweise des Riegelschaltkontaktes. Das Einstellen des Winkels zwischen den Hebelarmen ermöglicht eine besonders übersichtliche Anpassung der Vorrichtung an die gegebene bauliche Situation.The lever device preferably has two arms, which are mounted on the axle, with the on the first arm Force absorption point and on the second arm the force output point is provided and the setting of the lever device by changing the angle between the arms. This construction allows a compact design of the bolt switch contact. Setting the angle between the lever arms allow a particularly clear Adaptation of the device to the given structural situation.

Es ist vorteilhaft, wenn die Arme über eine Federeinrichtung miteinander gekoppelt sind. Die Federeinrichtung ermöglicht einerseits die Kraftübertragung von dem ersten Arm auf den zweiten Arm; andererseits gestattet sie ein Weiterbewegen des ersten Arms, obgleich der zweite Arm bereits die Schalteinrichtung betätigt hat und somit eventuell seine maximale Auslenkung erfahren hat.It is advantageous if the arms have a spring device are coupled together. The spring device enables on the one hand the power transmission from the first arm on the second arm; on the other hand, it allows moving on of the first arm, although the second arm already has actuated the switching device and thus possibly has experienced its maximum deflection.

Besonders bevorzugt ist es, wenn der zweite Arm von einer Rückstellfeder mit Kraft beaufschlagt wird. Auf diese Weise ist stets eine definierte Lage des zweiten Arms bezüglich des ersten Arms gegeben, wodurch die erfindungsgemäße Vorrichtung zuverlässig arbeitet.It is particularly preferred if the second arm of one Return spring is applied with force. In this way is always a defined position of the second arm given the first arm, whereby the device according to the invention works reliably.

Vorzugsweise wird der Winkel zwischen den Armen mittels einer Schraube verändert, welche in ein Innengewinde eines Arms eingeschraubt ist und sich an dem anderen Arm gegen die Kraft der Federeinrichtung abstützt. Für den Monteur ist somit die Justierung des Riegelschaltkontaktes in Abhängigkeit der baulichen Gegebenheiten besonders einfach, da er lediglich eine Schraube mehr oder weniger weit gegen die Spannung der Federeinrichtung verstellen muß. Insbesondere ist somit eine kontinuierliche Einstellung der relativen Lage der Arme durch eine einfache Maßnahme ermöglicht.The angle between the arms is preferably determined by means of a screw changed, which in an internal thread of a Arms is screwed in and against the other arm supports the force of the spring device. For the fitter the adjustment of the bolt switch contact is dependent the structural conditions are particularly simple, since it is just a screw more or less far against must adjust the tension of the spring device. In particular is thus a continuous adjustment of the relative Position of the arms made possible by a simple measure.

Bevorzugt ist eine Kontaktfahne der Schalteinrichtung von der Kraftabgabestelle der Hebeleinrichtung betätigbar. Eine Kontaktfahne kann in günstiger Weise eine Angriffsfläche zur Verfügung stellen, welche von einem auf einer Achse gelagerten Arm mit Kraft beaufschlagbar ist.A contact lug of the switching device from is preferred the power delivery point of the lever device can be actuated. A Contact flag can be a target in a favorable way make available which of a mounted on an axis Arm can be loaded with force.

Vorzugsweise ist als Schalteinrichtung ein Mikroschalter vorgesehen. Wegen ihrer geringen räumlichen Abmessung eignen sich Mikroschalter besonders gut für den platzsparenden Einbau des Riegelschaltkontaktes in einem Schließblech. Besonders vorteilhaft ist es, wenn die Schalteinrichtung mit einer Einbruchmelderzentrale verbunden ist. In der Einbruchmelderzentrale können eine Vielzahl von Signalen, welche verschiedensten Signalquellen entstammen können, sowie sonstige Parameter in komplexer Weise in Abhängigkeit voneinander verarbeitet werden.A microswitch is preferably used as the switching device intended. Suitable because of their small spatial dimensions microswitch is particularly good for the space-saving Installation of the bolt switch contact in a striking plate. Especially It is advantageous if the switching device with is connected to an intrusion control panel. In the intrusion control panel can have a variety of signals which can come from various signal sources, as well other parameters in complex ways depending on each other are processed.

Es ist vorteilhaft, wenn die Arme der Hebeleinrichtung in einem von dem Schloßriegel nicht mit Kraft beaufschlagten Zustand einen Winkel zwischen 20° und 110° einschließen. Damit ist ausreichend Toleranz zur Verfügung gestellt, damit der Riegelschaltkontakt bei verschiedensten baulichen Gegebenheiten zum Einsatz kommen kann.It is advantageous if the arms of the lever device in one not under power from the lock bolt Condition include an angle between 20 ° and 110 °. This provides sufficient tolerance thus the bolt switch contact in the most diverse structural conditions can be used.

Bevorzugt sind an dem Gehäuse Befestigungsvorrichtungen zur Befestigung in einem Schließblech vorgesehen. Dies macht die Montage des Riegelschaltkontaktes in der für ihn vorgesehenen Position in dem Schließblech besonders einfach. Fastening devices are preferred on the housing Attachment provided in a striking plate. This does the assembly of the bolt switch contact in the intended for him Position in the striking plate particularly easy.

Der Erfindung liegt die überraschende Erkenntnis zugrunde, daß durch die besondere Ausgestaltung einer Hebeleinrichtung in einem Riegelschaltkontakt praktisch beliebigen baulichen Gegebenheiten Rechnung getragen werden kann. Es ist nicht mehr erforderlich, Unterlegteile zu verwenden bzw. Aussparungen durch ein Auffräsen oder ein Aufbohren einzubringen und somit die Toleranzen bzw. die von vornherein unterschiedlichen Konstruktionen verschiedener Türen zu berücksichtigen. Eine hohe Funktionalität ist gesichert, und der Montageaufwand wird durch das erfindungsgemäße System erheblich vermindert.The invention is based on the surprising finding that by the special design of a lever device practically any structural in a bolt switch contact Circumstances can be taken into account. It is no longer required to use washers or Make recesses by milling or boring and thus the tolerances or those from the outset to consider different constructions of different doors. A high level of functionality is guaranteed, and the assembly effort is due to the system according to the invention significantly reduced.

Ferner ist ein zweiter Arm 24 vorgesehen, der mit dem ersten Arm 22 auf einer gemeinsamten Achse 26 sitzt. Der zweite Arm 24 kann eine Kontaktfahne 28, 28' eines Mikroschalters 30 mit Kraft beaufschlagen. Der Winkel zwischen den Armen 22, 24 ist über die Schraube 32 einstellbar. Die in der Fig. 2 dargestellte Stellung 28' der Schaltfahne 28, 28' entspricht nicht der dargestellten Stellung der Hebeleinrichtung 22, 24. Vielmehr entspricht diese Stellung 28' der im folgenden beschriebenen, in Fig. 3 dargestellten Situation.The bolt switch contact 20 comprises a first arm 22, which by excluding the lock bolt 20 with force is acted upon. A second arm 24 is also provided, the one with the first arm 22 on a common axis 26 sits. The second arm 24 can have a contact tab 28, 28 ' apply a force to a microswitch 30. The angle between the arms 22, 24 is adjustable via the screw 32. The position 28 'shown in FIG Switch flag 28, 28 'does not correspond to that shown Position of the lever device 22, 24. Rather corresponds this position 28 'of that described below, in Fig. 3 shown situation.

Fig. 3 zeigt die Anordnung gemäß Fig. 2 mit nunmehr ausgeschlossenem Schloßriegel 12. Im vorliegenden Fall ist der Schloßriegel 12 um 20 mm ausgefahren. Da der Abstand a zwischen Schließblech 6 und Türblatt 14 relativ groß ist, dringt der Schloßriegel 12 nur wenig in die Ausnehmung 8 ein, in welcher der Riegelschaltkontakt angeordnet ist. Da jedoch zwischen dem ersten Arm 22 und dem zweiten Arm 24 ein vergleichsweise großer Winkel vorliegt, gelingt es trotz des nur geringen Eindringens des Schloßriegels 12 in die Ausnehmung 8, den Mikroschalter 30 durch Umlegen der Schaltfahne 28, 28' in ihre maximal ausgelenkte Position 28' zu bewegen. Die dargestellte Position 28 der Schaltfahne 28, 28' entspricht der Position gemäß Fig. 2 und ist in Fig. 3 nur der Anschaulichkeit halber zusätzlich dargestellt. Im Bereich der Hebeleinrichtung 22, 24 ist eine Schraube 32 angeordnet, durch deren Drehung der Winkel zwischen dem ersten Arm 22 und dem zweiten Arm 24 verändert werden kann.Fig. 3 shows the arrangement of FIG. 2 with now excluded Lock bolt 12. In the present case is the Lock bolt 12 extended by 20 mm. Since the distance a between Striking plate 6 and door leaf 14 is relatively large, the lock bolt 12 penetrates only slightly into the recess 8 in which the bolt switch contact is arranged. There however, between the first arm 22 and the second arm 24 a comparatively large angle is successful despite the slight penetration of the lock bolt 12 in the recess 8, the microswitch 30 by flipping the Switch flag 28, 28 'in their maximum deflected position 28 'to move. Position 28 of the switch flag shown 28, 28 'corresponds to the position shown in FIG. 2 and is only additionally shown in FIG. 3 for the sake of clarity. In the area of the lever device 22, 24 there is one Screw 32 arranged by rotating the angle changed between the first arm 22 and the second arm 24 can be.

Eine veränderte Winkelstellung zwischen den Armen 22, 24 ist in Fig. 4 dargestellt. Mit dieser veränderten Winkelstellung wird der Situation Rechnung getragen, daß nunmehr der Abstand b zwischen dem Schließblech 4 und dem Türblatt 2 vergleichsweise gering ist. In Fig. 4 ist wiederum die Situation gezeigt, daß der Schloßriegel 12 nicht ausgeschlossen ist, so daß die Schaltfahne 28, 28' entsprechend der dargestellten Position 28 nicht von dem Arm 24 mit Kraft beaufschlagt ist. Somit wird der Mikroschalter 30 in der in Fig. 4 dargestellten Situation nicht betätigt, und es wird kein entsprechendes Signal an die Einbruchmelderzentrale 42 übermittelt.A changed angular position between the arms 22, 24 is shown in Fig. 4. With this changed angular position the situation is taken into account that now the distance b between the striking plate 4 and the door leaf 2 is comparatively low. 4 is again the Situation shown that the lock bolt 12 is not excluded is, so that the switching flag 28, 28 'accordingly the position 28 shown not with the arm 24 Force is applied. Thus, the microswitch 30 in the situation shown in Fig. 4 is not operated, and there is no corresponding signal to the intrusion control panel 42 transmitted.

In Fig. 5 ist nun eine Situation der in Fig. 4 dargestellten Anordnung gezeigt, bei der der Schloßriegel 12 vollständig ausgeschlossen ist. Man erkennt, daß erst im dargestellten Zustand, d.h. bei vollständig ausgeschlossenem Schloßriegel 12, der zweite Arm 24 hinreichend weit bewegt wurde, daß die Schaltfahne 28, 28' den Zustand 28' erreicht. Somit wird erst dann der Mikroschalter 30 geschaltet, und ein entsprechendes Signal wird an die Einbruchmelderzentrale 42 übermittelt. Somit gelingt es, obgleich der Abstand zwischen Schließblech und Türblatt 2 in der in Fig. 5 dargestellten Situation vergleichsweise gering ist, den Mikroschalter 30 tatsächlich erst zu dem Zeitpunkt zu betätigen, zu dem der Schloßriegel 12 tatsächlich vollständig ausgeschlossen ist. Damit wird den Anforderungen an die korrekte Justierung des Riegelschaltkontaktes genüge getan.In Fig. 5 is now a situation shown in Fig. 4 Arrangement shown in which the lock bolt 12 completely is excluded. It can be seen that only in the illustrated Condition, i.e. with completely excluded Lock bolt 12, the second arm 24 moved sufficiently far was that the switching flag 28, 28 'reaches state 28'. Thus, the microswitch 30 is only switched and a corresponding signal is sent to the intrusion control panel 42 transmitted. Thus it succeeds, although the Distance between striking plate and door leaf 2 in the in Fig. 5 situation is comparatively low, the To actually actuate microswitch 30 only at the time to which the lock bolt 12 is actually complete is excluded. This meets the requirements of the correct adjustment of the bolt switch contact is enough.

Die Kraftübertragung zwischen dem ersten Arm 22 und dem zweiten Arm 24 erfolgt über eine Federeinrichtung 34. Ferner wird der zweite Arm 24 durch eine Rückstellfeder mit Kraft beaufschlagt, so daß er stets eine definierte Position mit Bezug auf den Arm 22 einnimmt. Der Riegelschaltkontakt 20 ist über eine Schraubverbindung 36 in das Schließblech 4 einschraubbar und wird durch einen Befestigungszapfen 38 in seiner relativen Lage bezüglich des Schließbleches definiert. Der Zapfen 38 und die Schraubverbindung 36 sind an einem Gehäuse 40 angeordnet, welches ferner die Achse 26 für die Hebelarme 22 und 24 trägt. Die durch die Befestigungseinrichtungen 36, 38 bereitgestellte definierte Lage des Riegelschaltkontaktes 20 bezüglich des Schließbleches 4 erleichtert die zuverlässige Montage. Eine solche erleichterte Montage ist möglich, da der Riegelschaltkontakt 20 stets in derselben Position in das Schließblech 4 eingebaut werden kann, insbesondere unabhängig von dem Abstand zwischen Schließblech 4 und Türblatt 14. Ermöglicht wird dieser unabhängige Einbau durch die erfindungsgemäße Einstellmöglichkeit der Hebeleinrichtung 22, 24.The power transmission between the first arm 22 and the second arm 24 takes place via a spring device 34. Furthermore, the second arm 24 by a return spring acted upon with force so that it always has a defined one Assumes position with respect to the arm 22. The bolt switch contact 20 is a screw 36 in the Strike plate 4 can be screwed in and is secured by a fastening pin 38 in its relative position with respect to the Strike plate defined. The pin 38 and the screw connection 36 are arranged on a housing 40 which also carries the axis 26 for the lever arms 22 and 24. The provided by the fasteners 36, 38 defined position of the bolt switch contact 20 with respect to Strike plate 4 facilitates reliable assembly. A Such easier assembly is possible because the bolt switch contact 20 always in the same position in the Strike plate 4 can be installed, especially independently on the distance between the striking plate 4 and the door leaf 14. This independent installation is made possible by the possibility of adjusting the lever device according to the invention 22, 24.
