Description

Die Erfindung betrifft eine Verriegelungseinrichtung für ein Fenster oder dergleichen, dessen Flügelrahmen schwenkbar an einem Blendrahmen gelagert ist, umfassend einen in einer äußeren Falzumfangsfläche des Flügelrahmens anzuordnenden Verriegelungsbeschlag mit wenigstens einem in Umfangsrichtung der Falzumfangsfläche des Flügelrahmens zwischen einer Schließstellung und einer Öffnungsstellung verschiebbaren Riegelzapfen sowie ein in einer inneren Falzumfangsfläche des Blendrahmens anzuordnendes Schließblechteil mit einer zum Inneren des Blendrahmens und in Umfangsrichtung offenen Eingriffsaussparung für den Riegelzapfen.The invention relates to a locking device for a window or the like, the sash frame is pivotally mounted on a frame, comprising a locking fitting to be arranged in an outer folded peripheral surface of the sash frame with at least one locking pin displaceable in the circumferential direction of the folded peripheral surface of the sash frame between a closed position and an open position and an in an inner rabbet peripheral surface of the frame to be arranged striking plate part with an open to the inside of the frame and in the circumferential direction engagement recess for the locking pin.

Derartige Verriegelungseinrichtungen sind als Treibstangen-Verriegelungsbeschläge insbesondere in Form von Dehkipp-Verriegelungsbeschlägen für Türen und Fenster allgemein bekannt. Um mit solchen Verriegelungsbeschlägen ausgerüstete Türen oder Fenster mit Schließzustandssensoren für eine zentrale Überwachung des Schließzustands beispielsweise bei Alarmanlagen auszurüsten, sind bisher gesondert zu montierende und damit leicht als Alarmkontakte zu erkennende Sensoren erforderlich gewesen.Such locking devices are generally known as espagnolette locking fittings, in particular in the form of Dehkipp locking fittings for doors and windows. In order to equip doors or windows equipped with such locking fittings with closed-state sensors for central monitoring of the closed state, for example in the case of alarm systems, sensors which had to be installed separately and thus easily recognized as alarm contacts have hitherto been required.

So ist es aus der DE-OS 37 26 877 bekannt, im Flügelrahmen eines Fensters einen feststehenden Permanentmagnet und im Blendrahmen des Fensters einen Reed-Kontaktjeweils in Bohrungen der Rahmenteile feststehend anzuordnen. Der Reed-Kontakt ist in dem Blendrahmen frei sichtbar und kann lediglich Informationen über den Schließzustand des Flügelrahmens, nicht jedoch über dessen Verriegelung, liefern.It is known from DE-OS 37 26 877 to arrange a fixed permanent magnet in the casement of a window and a reed contact in the window frame of the window in a fixed manner in bores in the frame parts. The reed contact is freely visible in the frame and can only provide information about the closed state of the casement, but not about its locking.

Aus der DE-OS 30 41 148 ist es bekannt, mehrere Reed-Kontakte in einem gemeinsamen, nachträglich an dem Flügelrahmen oder dem Blendrahmen anzubringenden Gehäuse in einer Aussparung des Gehäuses anzuordnen.From DE-OS 30 41 148 it is known to arrange a plurality of reed contacts in a common housing to be retrofitted to the casement or the frame in a recess in the housing.

Schließlich ist es bekannt, an einem blendrahmenseitigen Schließblechteil, in welches ein am Flügelrahmen in dessen Falzumfangsrichtung beweglich geführter Riegelzapfen eingreift, einen Mikroschalteranzubringen, der über einen Hebel betätigt wird, wenn der Riegelzapfen in das Schließblechteil eingefahren ist, das Fenster also nicht nur geschlossen, sondern auch verriegelt ist. Eine solche Anordnung kann zwar den Verriegelungszustand des Fensters erfassen, ist aber vergleichsweise aufwendig und darüber hinaus als Meldekontakt erkennbar.Finally, it is known to mount a microswitch on a striker plate-side striking plate part, in which a locking pin is movably guided on the sash frame in the direction of the fold circumference thereof, which is actuated via a lever when the locking pin is retracted into the striking plate part, so that the window is not only closed, but instead is also locked. Such an arrangement can detect the locked state of the window, but is comparatively complex and can also be recognized as a signaling contact.

Es ist Aufgabe der Erfindung, eine Verriegelungseinrichtung für ein Fenster oder dergleichen, also beispielsweise eine Türe, mit einem Sensor auszurüsten, der nicht nur den Öffnungszustand, sondern auch dessen Verriegelungszustand erfassen kann, wobei der Sensor so gestaltet sein soll, daß er ohne Hilfsmittel nicht als solcher erkannt werden kann.It is an object of the invention to equip a locking device for a window or the like, for example a door, with a sensor which can detect not only the opening state but also its locking state, the sensor being designed so that it cannot be used without aids can be recognized as such.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Schließblechteil aus nichtmagnetischem Material besteht, daß der Riegelzapfen einen Permanentmagnet trägt und daß das Schließblechteil wenigstens einen Magnetfeldsensor aufweist, der in einer von der Seite des Blendrahmens her in das Schließblechteil eingesenkten und von der Eingriffsaussparung durch eine integrale Zwischenwand getrennten Aussparung des Schließblechteils angeordnet ist.This object is achieved in that the striking plate part is made of non-magnetic material, that the locking pin carries a permanent magnet and that the striking plate part has at least one magnetic field sensor, which is countersunk into the striking plate part from the side of the frame and from the engagement recess by an integral Intermediate wall separate recess of the strike plate part is arranged.

Ein solcher Riegelzapfen und das ihm zugeordnete Schließblechteil haben äußerlich die Gestalt herkömmlicher Verriegelungseinrichtungen, wie sie bei herkömmlichen Treibstrangen-Verriegelungsbeschlägen bekannt sind, und sie haben auch deren Funktion, sind also äußerlich ohne Hilfsmittel nicht zu unterscheiden. Da der Magnetfeldsensor auf den Permanentmagnet des Riegelzapfens nur dann anspricht, wenn dieser in das Schließblechteil eingreift, kann sowohl der Öffnungszustand des Flügelrahmens als auch der Verriegelungszustand überwacht werden.Such a locking pin and the striker plate part assigned to it have the shape of conventional locking devices, as are known in conventional driveline locking fittings, and they also have their function, that is, they cannot be distinguished externally without aids. Since the magnetic field sensor only responds to the permanent magnet of the locking pin when it engages in the striking plate part, both the opening condition of the sash frame and the locking condition can be monitored.

Die den Magnetfeldsensor aufnehmende Aussparung kann in Falzumfangsrichtung seitlich der Eingriffsaussparung vorgesehen sein, ist abervorzugsweise in einer die Eingriffsaussparung zur inneren Falzumfangsfläche des Blendrahmens hin begrenzenden Bodenwand des Schließblechteils angeordnet. Auf diese Weise steht vergleichsweise viel Platz für die Anordnung des Magnetfeldsensors zur Verfügung, ohne die Stabilität des Schließblechteils zu beeinträchtigen. Die für die Aufnahme des Magnetfeldsensors vorgesehene Aussparung schwächt lediglich einen begrenzten Bereich der Bodenwand, ohne daß die Außenabmessungen des Schließblechteils für die Unterbringung des Magnetfeldsensors vergrößert werden müßten.The recess accommodating the magnetic field sensor can be provided to the side of the engagement recess in the circumferential direction of the fold, but is preferably arranged in a bottom wall of the striking plate part delimiting the engagement recess to the inner circumferential fold surface of the frame. In this way, a comparatively large amount of space is available for the arrangement of the magnetic field sensor without impairing the stability of the striking plate part. The recess provided for receiving the magnetic field sensor only weakens a limited area of the bottom wall, without the outer dimensions of the striking plate part having to be enlarged to accommodate the magnetic field sensor.

Das Schließblechteil hat zweckmäßigerweise langgestreckte Form und enthält in einem ersten, von Durchbrechungen freien Abschnitt die Eingriffsaussparung, während in einem daran anschließenden zweiten Teil Durchtrittslöcher für Befestigungsschrauben vorgesehen sind. Die insbesondere in der Bodenwand der Eingriffsaussparung für die Aufnahme des Magnetfeldsensors vorgesehene Aussparung kann beide Abschnitte überlappen, insbesondere wenn der Magnetfeldsensor durch einen vergleichsweise langen Reed-Kontakt gebildet wird. Die Zuleitungen zu dem Magnetfeldsensor treten zweckmäßigerweise im Bereich des Übergangs vom ersten zum zweiten Abschnitt des Schließblechteils aus, um das Schließblechteil gegebenenfalls in Falzumfangsrichtung justieren zu können, ohne daß die Gefahr besteht, daß die Austrittsöffnung des die Zuleitungen im Blendrahmen aufnehmenden Kabelkanals sichtbar wird.The striking plate part expediently has an elongated shape and contains the engagement recess in a first section free of perforations, while passage holes for fastening screws are provided in a subsequent second part. The recess provided in particular in the bottom wall of the engagement recess for receiving the magnetic field sensor can overlap both sections, in particular if the magnetic field sensor is formed by a comparatively long reed contact. The leads to the magnetic field sensor expediently emerge in the region of the transition from the first to the second section of the striking plate part in order to be able to adjust the striking plate part in the circumferential direction of the fold if necessary, without the risk that the outlet opening of the cable duct receiving the leads in the frame can be seen.

In einer bevorzugten Ausgestaltung enthält der Blendrahmen an der von dem Schließblechteil überdeckten Stelle seiner inneren Falzumfangsfläche eine Staukammer zur Aufnahme einer Reserve an Zuleitungen des Magnetfeldsensors und/oder eines Kupplungssteckers der Zuleitungen. Diese Maßnahme erleichtert die Montage und gegebenenfalls einen späteren Austausch des Schließblechteils.In a preferred embodiment, the frame contains a storage chamber at the location of its inner circumferential fold surface covered by the striking plate part for receiving a reserve of leads of the magnetic field sensor and / or a coupling plug of the leads. This measure facilitates the assembly and, if necessary, a later replacement of the striking plate part.

In einer bevorzugten Ausgestaltung der Erfindung ist der Magnetfeldsensorals Hall-Sensor, insbesondere als Hall-Schalter, ausgebildet. Magnetfeldsensoren dieser Art sind vergleichsweise flach, so daß sie problemlos insbesondere in einer Aussparung der Bodenwand der Eingriffsaussparung des Schließblechs untergebracht werden können.In a preferred embodiment of the invention, the magnetic field sensor is designed as a Hall sensor, in particular as a Hall switch. Magnetic field sensors of this type are comparatively flat, so that they can easily be accommodated in particular in a recess in the bottom wall of the engagement recess of the striking plate.

Von besonderer Bedeutung sind Ausgestaltungen, bei welchen das Schließblechteil in der den Magnetfeldsensor aufnehmenden Aussparung zusätzlich eine durch externe Adressensignale steuerbare Steuerschaltung enthält, die selektives Abfragen des Magnetfeldsensor ermöglicht. Durch die selektive Adressierung beispielsweise in einem Zeitmultiplexzyklus lassen sich eine Vielzahl Magnetfeldsensoren zentral abfragen, ohne daß es aufwendiger Verteiiereinrichtungen bedarf. Insbesondere kann eine Vielzahl Magnetfeldsensoren über einen gemeinsamen Datenbus sowohl adressiert, als auch deren Meldeinformationen abgefragt werden. Mit geringem Verkabelungsaufwand lassen sich auf diese Weise mehrere Magnetfeldsensoren unterschiedlicher Funktionen selektiv, zum Beispiel zeitlich nacheinander, abfragen. Dies ist insbesondere dann von Vorteil, wenn mehrere Magnetfeldsensoren in einem gemeinsamen Schließblechteil untergebracht sind, wo sie in unterschiedlichen Positionen auf den Permanentmagnet des Verriegelungszapfens ansprechen. Für adressierbare Magnetfeldsensoren eignen sich insbesondere Hall-Sensoren, die zusammen mit der Steuerschaltung in integrierter Schaltkreistechnik auf einem gemeinsamen Chip realisiert werden können.Embodiments are particularly important in which the striking plate part in the recess receiving the magnetic field sensor additionally contains a control circuit which can be controlled by external address signals and which enables selective interrogation of the magnetic field sensor. Through the selective addressing, for example in a time-division multiplex cycle, a large number of magnetic field sensors can be queried centrally, without the need for complex distribution devices. In particular, a large number of magnetic field sensors can both be addressed via a common data bus and their reporting information can be queried. In this way, several magnetic field sensors with different functions can be interrogated selectively, for example one after the other, with little wiring effort. This is particularly advantageous if a plurality of magnetic field sensors are accommodated in a common striking plate part, where they respond to the permanent magnet of the locking pin in different positions. Hall sensors, which can be implemented together with the control circuit in integrated circuit technology on a common chip, are particularly suitable for addressable magnetic field sensors.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert. Hierbei zeigt:

  • Fig. 1 eine perspektivische Darstellung einer Treibstangen-Eckumlenkung eines Fensters oder einer Türe und
  • Fig. 2 eine teilweise aufgebrochene perspektivische Darstellung eines Schließblechteils der Eckumlenkung.
An exemplary embodiment of the invention is explained in more detail below with reference to a drawing. Here shows:
  • Fig. 1 is a perspective view of a drive rod corner deflection of a window or a door and
  • Fig. 2 is a partially broken perspective view of a striking plate part of the corner drive.

Fig. 1 zeigt schematisch angedeutet einen Eckbereich eines Flügelrahmens 1 eines Fensters oder einer Türe, die schwenkbar, insbesondere um eine vertikale Achse drehbar und eine horizontale Achse kippbar an einem Blendrahmen 3 gelagert ist. In einer äußeren Falzumfangsfläche 5 des Flügelrahmens 1 sind in Umfangsrichtung des Flügelrahmens 1 bewegliche Treibstangen 7 eines nicht näher dargestellten Verriegelungsbeschlags, insbesondere eines Drehkipp-Verriegelungsbeschlags, angeordnet, die im Bereich zumindest der von der Drehachse und der Schwenkachse entfernten oberen Ecke des Flügelrahmens 1 durch eine Treibstangen-Eckumlenkung 9 miteinanderverbunden sind. Die Eckumlenkung 9 umfaßteinen Stulpschienenwinkel 11, an dessen Schenkeln Anschlußstücke 13 für die Treibstangen 7 geführt sind. Die Anschlußstücke 13 sind im Eckbereich des Stulpschienenwinkels 11 durch ein flexibles Stahlband 15 miteinander gekuppelt und tragen auf der Außenseite des Stulpschienenwinkels 11 Riegelzapfen 17, 19, denen auf der inneren Falzumfangsfläche des Blendrahmens 3 Schließblechstücke 21 zugeordnet sind. Die Schließblechstücke 21, von denen Fig. 1 lediglich eines zeigt, haben langgestreckte Form und sind in einem ersten Abschnitt mit einem sowohl zur Innenseite des Blendrahmens 3 als auch auf einer Seite in Umfangsrichtung offenen Eingriffsaussparung 23 für den Riegelzapfen 17 bzw. 19 versehen. In einem zweiten Abschnitt in Längsrichtung des Schließblechteils 21 neben der Eingriffsaussparung 23 ist das Schließblechteil 21 mit mehreren Durchgangslöchern 25 für die Schraubbefestigung des Schließblechteils 21 am Blendrahmen 3 versehen.Fig. 1 shows schematically indicated a corner region of a casement 1 of a window or a door, which is pivotally mounted, in particular rotatable about a vertical axis and tiltable on a frame 3, a horizontal axis. In an outer circumferential rabbet surface 5 of the sash frame 1, movable connecting rods 7 of a locking fitting (not shown in detail), in particular a tilt-and-turn locking fitting, are arranged in the circumferential direction of the sash frame 1, which by at least the upper corner of the sash frame 1 removed from the axis of rotation and the pivot axis by a Espagnolette corner deflection 9 are interconnected. The corner deflection 9 comprises a faceplate angle bracket 11, on the legs of which connecting pieces 13 for the drive rods 7 are guided. The connecting pieces 13 are coupled to one another in the corner region of the faceplate angle 11 by a flexible steel band 15 and carry locking pins 17, 19 on the outside of the faceplate angle 11, to which 3 striking plate pieces 21 are assigned on the inner circumferential surface of the frame 3. The striking plate pieces 21, only one of which is shown in FIG. 1, have an elongated shape and are provided in a first section with an engagement recess 23 for the locking pin 17 and 19, which is open both to the inside of the frame 3 and on one side in the circumferential direction. In a second section in the longitudinal direction of the striking plate part 21 in addition to the engagement recess 23, the striking plate part 21 is provided with a plurality of through holes 25 for screw fastening the striking plate part 21 to the frame 3.

Einer der Riegelzapfen, hier der in der horizontalen oberen Falzumfangsfläche des Flügelrahmens 1 vorgesehene Riegelzapfen 17, trägt verdeckt und damit von außen nicht sichtbar einen Permanentmagnet 27, dem in dem Schließblechteil 21 ein Magnetfeldsensor 29 zugeordnet ist. Der Magnetfeldsensor 29 spricht nur dann auf das Magnetfeld des Permanentmagnets 27 an, wenn der Riegelzapfen 17 in die Eingriffsaussparung 23 eingeführt ist, das Fenster also nicht nur geschlossen, sondern auch verriegelt ist.One of the locking pins, here the locking pin 17 provided in the horizontal upper rebate circumferential surface of the casement 1, carries a permanent magnet 27 concealed and thus not visible from the outside, to which a magnetic field sensor 29 is assigned in the striking plate part 21. The magnetic field sensor 29 only responds to the magnetic field of the permanent magnet 27 when the locking pin 17 is inserted into the engagement recess 23, that is to say that the window is not only closed but also locked.

Fig. 2 zeigt Einzelheiten des Schließblechteils 21. Es ist als Gußformteil aus einem nichtmagnetischen Material, insbesondere einem nichtmagnetischen Metall, wie zum Beispiel als Zink-Druckguß-Formteil, ausgebildet und enthält in der die Eingriffsaussparung 23 zum Blendrahmen 3 hin begrenzenden Bodenwand 31 auf der zum Blendrahmen 3 weisenden Seite eine Aussparung 33, in der der Magnetfeldsensor 29 angeordnet und durch Gießharz 35 geschützt untergebracht ist. Da die Bodenwand 31 keine Durchbrechungen aufweist, ist bei montiertem Schließblechteil 21 nicht erkennbar, daß es sich um ein Schließblechteil mit Meldefunktion handelt.Fig. 2 shows details of the striking plate part 21. It is designed as a molded part made of a non-magnetic material, in particular a non-magnetic metal, such as a die-cast zinc part, and contains in the engagement recess 23 towards the frame 3 bottom wall 31 on the to the frame 3 side facing a recess 33 in which the magnetic field sensor 29 is arranged and housed protected by casting resin 35. Since the bottom wall 31 has no openings, it cannot be seen when the striking plate part 21 is mounted that it is a striking plate part with a signaling function.

Die Aussparung 33 greift über die Eingriffsaussparung 23 hinweg auf den mit Durchgangslöchern 25 versehenen Abschnitt des Schließblechteils 21 über. Zuleitungen 37 des Magnetfeldsensors 29 treten im Bereich des den Durchtrittslöchern 25 benachbarten Endes der Aussparung 33 zum Blendrahmen 3 hin aus. Im Blendrahmen 3 ist zur Aufnahme einer Reserve der Zuleitung 37 sowie gegebenenfalls einer Steckerkupplung 39 eine Staukammer41 vorgesehen, die von dem Schiie&biechteii 21 vollständig überdeckt wird. Die Staukammer 41 und gegebenenfalls die Steckerkupplung 39 erleichtert die Montage und das Auswechseln des Schließblechteils 21.The cutout 33 extends over the engagement cutout 23 onto the section of the striking plate part 21 provided with through holes 25. Leads 37 of the magnetic field sensor 29 emerge in the region of the end of the cutout 33 adjacent to the through holes 25 to the frame 3. In the frame 3 is to hold a reserve of the supply line 37 and possibly a connector 39 a stowage chamber 41 is provided which is completely covered by the slide 21. The stowage chamber 41 and possibly the plug coupling 39 facilitate the assembly and the replacement of the striking plate part 21.

Fig. 1 zeigt lediglich einen einzigen Magnetfeldsensor. An dem Blendrahmen 3 können jedoch auch mehrere Magnetfeldsensoren, insbesondere auch mehrere Magnetfeldsensoren an einem gemeinsamen Schließblechteil, vorgesehen sein, um Öffnungszustand und Verriegelungszustand des Fensters bzw. der Türe gesondert überwachen zu können. Die Magnetfeldsensoren mehrerer Fenster sind an eine gemeinsame Überwachungszentrale 43, beispielsweise einer Alarmanlage, angeschlossen. Um den Verkabelungsaufwand geringzuhalten, ist jedem der Magnetfeldsensoren 29 innerhalb derAussparung 33 des Schließblechteils 21 eine durch Adressensignale der Zentrale 43 selektiv adressierbare Steuerschaltung 45 zugeordnet, die die Meldesignale des zugeordneten Magnetfeldsensors 29 selektiv abruft. Die Zentrale 43 arbeitet nach Art einer Zeitmultiplex-Steuerung und ruft in einem vorbestimmten Zyklus die Magnetfeldsensoren der Reihe nach für die Abgabe ihrer Meldesignale auf. Im Einzelfall können die Magnetfeldsensoren 29 deshalb parallel an einen gemeinsamen Datenbus 45 angeschlossen sein, über den zum Beispiel zeitlich versetzt nach der Übertragung eines Adressensignals das Meldesignal des durch das Adressensignal des aufgerufenen Magnetfeldsensors 29 zurück zur Zentrale 43 übertragen wird.1 shows only a single magnetic field sensor. However, a plurality of magnetic field sensors, in particular also a plurality of magnetic field sensors on a common striking plate part, can also be provided on the frame 3 in order to be able to separately monitor the opening state and locking state of the window or the door. The magnetic field sensors of several windows are connected to a common monitoring center 43, for example an alarm system. In order to keep the wiring effort low, each of the magnetic field sensors 29 within the recess 33 of the striking plate part 21 is assigned a control circuit 45 which can be selectively addressed by address signals from the control center 43 and which selectively retrieves the signal signals of the associated magnetic field sensor 29. The control center 43 operates in the manner of a time-division multiplex control and, in a predetermined cycle, calls up the magnetic field sensors in order to emit their signaling signals. In individual cases, the magnetic field sensors 29 can therefore be connected in parallel to a common data bus 45, via which, for example, after the transmission of an address signal, the signal signal of the magnetic field sensor 29 called up by the address signal of the called magnetic field sensor 29 is transmitted back to the control center 43.

Bei dem Magnetfeldsensor 29 kann es sich um einen Reed-Kontakt handeln. Zweckmäßigerweise handelt es sich jedoch um einen Hall-Sensor, da sich derartige Sensoren zusammen mit der adressierbaren Steuerschaltung in integrierter Schaltkreistechnik auf einem gemeinsamen Chip herstellen lassen.The magnetic field sensor 29 can be a reed contact. Expediently, however, it is a Hall sensor, since such sensors can be produced together with the addressable control circuit in integrated circuit technology on a common chip.
