Description

Die Erfindung betrifft eine Anordnung zur Verschlussüberwachung.The invention relates to an arrangement for closure monitoring.

Derartige Anordnungen sind bereits bekannt. Die DE 9011016 U1 schlägt die Anordnung eines mit einem Permanentmagneten versehenen Riegelelementes und einem diesem zugeordneten Riegeleingriff mit einem Magnetfeldsensor in Form eines Reed- oder Hallsensors vor. Das Einnehmen der Verriegelungsstellung führt zu einer Annäherung des Permanentmagneten an den Sensor, so dass dessen Signal ausgewertet werden kann. Hierzu ist eine Steuerschaltung vorgesehen, welche eine Vielzahl von Sensoren adressieren und auswerten kann. Die verdeckte Anordnung des Sensors in dem Riegeleingriff und die Anordnung des Permanentmagneten in dem Riegelelement machen eine Nachrüstung unmöglich.Such arrangements are already known. The DE 9011016 U1 proposes the arrangement of a locking element provided with a permanent magnet and a locking engagement associated therewith with a magnetic field sensor in the form of a reed or Hall sensor. The assumption of the locking position leads to an approximation of the permanent magnet to the sensor, so that its signal can be evaluated. For this purpose, a control circuit is provided which can address and evaluate a large number of sensors. The concealed arrangement of the sensor in the locking engagement and the arrangement of the permanent magnet in the locking element make retrofitting impossible.

Bei der aus der EP 0600795 B1 bekannten Anordnung sind Codeträger vorgesehen, dessen Übereinstimmung mit einem in einer Auswerteinheit referenzierten Code zur Sicherstellung einer definierten Schaltstellung verglichen wird.At the time of the EP 0600795 B1 known arrangement Code carriers are provided, the match is compared with a referenced in an evaluation unit code to ensure a defined switching position.

Die DE 29519486 U1 schlägt eine Anordnung vor, bei der eine Vorrichtung am Flügel befestigt wird, die ein Geberelement lagert. Das Geberelement ist mit einem Verriegelungselement einer Verriegelungsvorrichtung koppelbar und wird bei Verlagerung des Verriegelungselementes mitgeführt. Die Kopplung erfolgt über einen Taststift, der in Richtung des Verriegelungselementes mittels einer Feder kraftbeaufschlagt ist. In einer zu detektierenden Schaltstellung liegen sich der Taststift und ein Detektorelement gegenüber. Die Anordnung ist zum Zwecke der einfachen Nachrüstung ausgelegt, setzt aber eine kabelgestützte Anbindung des Detektors voraus.The DE 29519486 U1 proposes an arrangement in which a device is attached to the wing, which supports a donor element. The transmitter element can be coupled to a locking element of a locking device and is carried along when the locking element is displaced. The coupling takes place via a stylus, which is subjected to a force in the direction of the locking element by means of a spring. In a switching position to be detected, the stylus and a detector element are opposite. The arrangement is designed for the purpose of simple retrofitting, but requires a cable-supported connection of the detector.

Eine Ausgestaltung nach der EP 0743410 A2 sieht eine Anordnung entsprechend der DE 9011016 U1 vor, bei dem eine Auswerteinheit eine Initialisierungsphase vorsieht, in der Referenzgrößen der Schaltstellungen ermittelt werden und fortan ein manipulationssicherer Betrieb durch Vergleich dieser Werte mit den Ist-Werten erreicht werden soll. Hierzu ist ein im Verriegelungselement angebrachter Dauermagnet und mehrere im Riegeleingriff aufgenommene Sensoren erforderlich. Die Anordnung ist daher aufwendig und nicht nachrüstbar.An embodiment according to the EP 0743410 A2 sees an arrangement according to the DE 9011016 U1 before, in which an evaluation unit provides an initialization phase, are determined in the reference variables of the switch positions and henceforth a manipulation-safe operation is to be achieved by comparing these values with the actual values. For this purpose, a permanent magnet mounted in the locking element and a plurality of sensors received in the locking engagement are required. The arrangement is therefore complicated and can not be retrofitted.

Die US 5912619 A schlägt optische Mittel vor, so dass auf magnetische Elemente verzichtet werden kann. Hiermit kann allerdings nur der Schließzustand des Flügels detektiert werden.The US 5912619 A suggests optical means, so that can be dispensed with magnetic elements. Hereby, however, only the closed state of the wing can be detected.

Die DE 10059582 A1 offenbart eine Anordnung, bei der an einer Treibstange einer Verriegelungseinrichtung ein Meldegeber angebracht ist, eine Auswerteinheit am Flügel und eine Basisstation am Rahmen. Der Meldegeber ist als Permanentmagnet und der Sensor als Reedkontakt oder Hallsensor offenbart. Die Auswerteinheit umfasst einen nichtflüchtigen Speicher, der einen Identifizierungscode aufnimmt. Dies ermöglicht über einen Transponder eine Identifizierung gegenüber der Basisstation. Über den Transponder werden Signale und Daten ausgetauscht. Dieser Austausch kann zyklisch erfolgen. Auch hier ist ein Nachrüsten, insbesondere aufgrund der notwendigen Energiebereitstellung, für die Basisstation nicht möglich. Auch das Anbringen des Meldegebers ist mit umfangreichen Montagearbeiten verbunden.The DE 10059582 A1 discloses an arrangement in which on a drive rod of a locking device a detector transmitter is mounted, an evaluation unit on the wing and a base station on the frame. The message transmitter is disclosed as a permanent magnet and the sensor as a reed contact or Hall sensor. The evaluation unit comprises a non-volatile memory which receives an identification code. This allows identification via a transponder with respect to the base station. Signals and data are exchanged via the transponder. This exchange can be cyclical. Again, retrofitting, in particular due to the necessary energy supply, for the base station is not possible. Attaching the annunciator is also associated with extensive assembly work.

Aus der EP 1043461 A1 ist eine Anordnung bekannt, bei der an einem flügelseitigen Verriegelungselement eine Adapterschiene gekoppelt wird, welche eine elektronische Schaltung als Codeträger und eine Ferrit-Sendeantenne beinhaltet. Dieser Schaltung ist am feststehenden Rahmen eine Ferrit-Empfangsantenne zugeordnet, so dass bei gegenüberstehenden Sende- und Empfangsantennen eine induktive Energie- und Signalübertragung möglich ist. Ein Lernmodus ermöglicht einen Abgleich des Senders und einer rahmenseitigen Auswerteinheit. Die Anordnung kann prinzipiell an bestehenden Verriegelungseinrichtungen nachträglich angebracht werden.From the EP 1043461 A1 An arrangement is known in which at a wing-side locking element, an adapter rail is coupled, which includes an electronic circuit as a code carrier and a ferrite transmitting antenna. This circuit is assigned to the fixed frame, a ferrite receiving antenna, so that in opposite transmitting and receiving antennas, an inductive energy and signal transmission is possible. A learning mode allows an adjustment of the transmitter and a frame-side evaluation unit. The arrangement can in principle be subsequently attached to existing locking devices.

Nachteilig dabei ist es, dass es eine Vielzahl von Verriegelungselementen gibt, die jeweils angepasste Adapterschienen notwendig machen und zudem das Konzept des Codeträgers mit zwei Ferritantennen aufwendig ist. Die notwendige Energie für den Betrieb ist beachtlich. Die Einrichtung muss daher mit einer Gebäudeenergieversorgung gekoppelt werden.The disadvantage here is that there are a variety of locking elements that make each adapted adapter rails necessary and also the concept of the code carrier with two ferrite antennas is expensive. The necessary energy for the Operation is considerable. The device must therefore be coupled with a building energy supply.

Nachteilig bei den genannten Ausgestaltungen ist es, dass eine Nachrüstung nur unter Schwierigkeiten möglich ist und dass die Verriegelungselemente entweder gekoppelt oder an Adapter angepasst werden müssen, deren Montage jeweils mit den rahmenseitigen Komponenten abgestimmt sein müssen.A disadvantage of the aforementioned embodiments is that retrofitting is possible only with difficulty and that the locking elements must either be coupled or adapted to adapters whose assembly must be coordinated with the frame-side components.

Der Erfindung liegt daher die Beseitigung dieser Nachteile zugrunde.The invention is therefore based on the elimination of these disadvantages.

Zur Lösung sieht die Erfindung die Merkmale des Anspruchs 1 vor.To solve the invention provides the features of claim 1.

Die Anordnung einen Sensors, der die Änderung des Erdmagnetfeldes durch das Treibstangenelement detektiert und dem eine Auswerteinheit zugeordnet ist, welche die Änderung einer Schaltstellung zuordnet, setzt lediglich das Vorhandensein eines, das Erdmagnetfeld beeinflussenden Metallgegenstandes voraus. Hierzu reicht eine Treibstange eines Treibstangenelementes aus, Gleichwohl kann im Sinne der Erfindung ein Verriegelungselement genutzt werden, welches der Mehrzahl der Verriegelungselemente entspricht, die zur Verriegelung des Flügels vorgesehen sind und als Wirkkomponente mit dem Sensor wirken. Ein Koppeln oder Befestigen von Permanentmagneten ist daher entbehrlich. Damit eine Differenzierung bezüglich der unterschiedlichen Schaltstellungen des Verriegelungselementes erfolgen kann, findet eine Auswertung des Sensorsignals in der Auswerteinheit statt, so dass auch ggfs. schwache Differenzierungen im Sensorsignal ausgewertet und Schaltstellungen zugeordnet werden können.The arrangement of a sensor which detects the change in the earth's magnetic field by the drive rod element and which is associated with an evaluation unit, which assigns the change of a switching position, only requires the presence of a metal object influencing the earth's magnetic field. For this purpose, a drive rod of an espagnolette element is sufficient, However, according to the invention, a locking element can be used, which corresponds to the plurality of locking elements, which are provided for locking the wing and act as an active component with the sensor. Coupling or fixing of permanent magnets is therefore unnecessary. So that a differentiation with respect to the different switching positions of the locking element can take place, an evaluation of the sensor signal takes place in the evaluation, so that even if necessary. Weak differentiations in the sensor signal evaluated and switch positions can be assigned.

Mit Vorteil zur Montage und Signalerzeugung hat das Treibstangenelement einen Kupplungsschuh zur Kopplung mit benachbarten Treibstangenelementen. Dieser Bauraum bleibt aufgrund der hier vorzusehenden Längenanpassungen der Beschlagbauteile frei von ergänzenden Funktionsteilen des Treibstangenbeschlages.Advantageously for mounting and signal generation, the drive rod element has a clutch shoe for coupling with adjacent drive rod elements. This space remains due to the length adjustments to be provided here of the hardware components of complementary functional parts of the espagnolette fitting.

Um die Verfügbarkeit des Systems jederzeit sicherzustellen, ist vorgesehen, dass die Auswerteinheit Referenzwerte in Bezug auf die Schaltstellungen des Treibstangenelementes relativ zum Sensor speichert.In order to ensure the availability of the system at any time, it is provided that the evaluation unit stores reference values relating to the switching positions of the drive rod element relative to the sensor.

Eine energiesparende Ausgestaltung sieht vor, dass die Auswerteeinheit Ist-Werte des Sensors in zyklischen Abständen mit den Referenzwerten vergleicht.An energy-saving embodiment provides that the evaluation unit compares actual values of the sensor in cyclic intervals with the reference values.

Eine einfache Nachrüstung kann dadurch erfolgen, dass die Auswerteinheit zusammen mit dem Sensor neben dem Riegelelement auf einer Stulpschiene befestigt ist.A simple retrofit can be done by the evaluation unit is fastened together with the sensor next to the locking element on a faceplate.

Dabei kann weiter vorteilhaft vorgesehen werden, dass Auswerteinheit eine Einrichtung zur drahtlosen Übertragung eines Zustandssignals enthält.In this case, it can further be advantageously provided that the evaluation unit contains a device for the wireless transmission of a status signal.

Ein Verfahren zur Inbetriebnahme einer Anordnung enthält zumindest einen Referenzierungslauf für die Auswerteinheit, in dem sich das Riegelelement in Öffnungsstellung befindet und der Messwert des Sensors ermittelt wird.A method for starting up an arrangement contains at least one referencing run for the evaluation unit, in which the locking element is in the open position and the measured value of the sensor is determined.

Um weitere Schaltstellungen sicher detektieren zu können, ist eine weitergehende Referenzierungen für jede über die Anordnung einstellbare Schaltstellung vorgesehen.In order to be able to reliably detect further switching positions, further references are provided for each switching position which can be set via the arrangement.

Manipulationen an dem System können erkannt werden, indem bei einem von den ermittelten Referenzwerten abweichenden Signalen ein Alarm ausgelöst wird.Tampering with the system can be detected by triggering an alarm if the signal differs from the reference values determined.

Schließlich bietet die Verwendung eines Magnetfeldsensors zur Erfassung von Magnetfeldänderungen an einem Verriegelungselement einer Verriegelungsvorrichtung eines Fensters oder einer Tür, bei der dass der Magnetfeldsensor einem Standard-Riegelelement zugeordnet ist, eine kostengünstige und einfache Ausgestaltung.Finally, the use of a magnetic field sensor to detect magnetic field changes on a locking element of a locking device of a window or door in which the magnetic field sensor is associated with a standard locking element provides a low-cost and simple configuration.

Bei dem in Fig. 1 dargestellten Teilbereich eines Treibstangenbeschlages 1 ist eine Eckumlenkung 2 und eine Ausstellvorrichtung 3 vorgesehen. Die Eckumlenkung 2 weist eine Treibstange 4 auf, welche über ein Umlenkglied 5 mit einer Treibstange 6 gekoppelt ist. Die Treibstangen 4, 6 weisen Kupplungsschuhe 7, 8 auf, welche zur Kopplung benachbarter Treibstangen, hier dargestellt, Treibstange 9 der Ausstellvorrichtung 3 dienen. Die Treibstange 9 greift dazu in bekannter Weise mit einer Außenverzahnung 10 in eine Innenverzahnung des Kupplungsschuhs 8 ein.At the in Fig. 1 shown portion of an espagnolette fitting 1 is a corner drive 2 and a display device 3 is provided. The corner drive 2 has a drive rod 4, which is coupled via a deflection member 5 with a drive rod 6. The drive rods 4, 6 have coupling shoes 7, 8, which serve for coupling adjacent drive rods, shown here, drive rod 9 of the display device 3. The drive rod 9 engages in a known manner with an external toothing 10 in an internal toothing of the clutch shoe 8 a.

Die Treibstangen 4, 6 und 9 sind unterhalb eines Deckwinkels 11 bzw. einer Stulpschiene 12 geführt. Die Stulpschiene 12 und der Deckwinkel 11 sind dem Flügel des Fensters oder der Tür ortsfest zugeordnet und decken eine Beschlagaufnahmenut des Flügels ab.The drive rods 4, 6 and 9 are guided below a cover angle 11 and a face plate 12. The faceplate 12 and the cover angle 11 are assigned to the wing of the window or door fixed and cover a Beschlagaufnahmenut the wing from.

Auf der Stulpschiene 12 ist eine Verschlussüberwachung 13 angeordnet, mit der der jeweilige Schaltzustand des Treibstangenbeschlages detektiert werden soll. Der Treibstangenbeschlag 1 soll im Ausführungsbeispiel drei Schaltstellungen aufweisen. In einer Verschlussstellung 14 sind Riegelelemente 15 jeweils rahmenseitig ortsfest angebrachten Riegeleingriffen zugeordnet und hintergreifen diese an Riegelstegen. In einer Drehöffnungsstellung 16 sind die Riegelelemente 15 aus dem Eingriff mit den Riegeleingriffen herausbewegt und ein Ausstellarm 17 der Ausstellvorrichtung 3 ist über einen Riegel 18 gegen eine Bewegung relativ zur Stulpschiene 12 gesperrt. Der Flügel kann um eine seitliche lotrechte Achse verschwenkt werden. Schließlich ist eine Kippöffnungsstellung 19 vorgesehen, in der der Riegel 18 den Ausstellarm 17 freigibt und dieser relativ zur Spulschiene 12 verschwenkt werden kann. Dabei wird gleichzeitig in bekannter Weise eine Kippverriegelung wirksam, die den Flügel am untern horizontalen Rand festlegt und eine Relativneigung des Flügels zum Rahmen ermöglicht.On the face plate 12, a closure monitoring 13 is arranged, with which the respective switching state of the espagnolette is to be detected. The espagnolette fitting 1 should have three switching positions in the embodiment. In a closed position 14 locking elements 15 are each assigned to the frame side fixedly mounted bolt engagement and engage behind this on bar bars. In a rotational opening position 16, the locking elements 15 are moved out of engagement with the latching engagements and a deployment arm 17 of the deployment device 3 is locked by a latch 18 against movement relative to the face-plate 12. The wing can be pivoted about a lateral vertical axis. Finally, a Kippöffnungsstellung 19 is provided, in which the latch 18 releases the stay 17 and this can be pivoted relative to the Spulschiene 12. At the same time a tilt lock is effective in a known manner, which defines the wing on the lower horizontal edge and allows a relative inclination of the wing to the frame.

Die angedeuteten Schaltstellungen 14, 16, 19 symbolisieren schematisiert die verschiedenen Lagen des Riegelelements 15, welches nur eines einer Vielzahl von Riegelelementen darstellt.The indicated switching positions 14, 16, 19 schematically symbolize the various positions of the locking element 15, which represents only one of a plurality of locking elements.

Die Verschlussüberwachung 13 soll nun in Abhängigkeit vom Schaltzustand der Treibstangen 4, 6, 9 ein Signal bereitstellen, welches für die jeweilige Schaltstellung signifikant ist. Dazu sieht die Anordnung einen Sensor vor, der die Änderung des Erdmagnetfeldes durch das Treibstangenelement detektiert und dem eine Auswerteinheit zugeordnet ist, welche die Änderung einer Schaltstellung zuordnet. Eine messbare Störung und damit Änderung des Erdmagnetfeldes kann bereits durch die Treibstange 6 selbst erfolgen, welche durch Bohrungen, Kröpfungen und daran befestigte Bauteile eine deutliche Magnetfeldänderung bewirkt, wenn sie verschoben wird. Daher benötigt die Verschlussüberwachung 13 keinen speziellen Melder, der zur Signalerzeugung beiträgt. Der verwendete Sensor ist beispielsweise ein Xtrinsic MAG3110 Three-Axis, Digital Magnetometer der Firma freescale xtrinsic. Dieser Sensor liefert je nach Relativlage der Treibstange 6, 9 ein charakteristisches Signal, welches beispielhaft in der Fig. 4 dargestellt ist. Jeder der drei Raumachsen wird mit einem eigenen Signal ausgegeben. Dadurch ergibt sich für jede Stellung der Treibstangen 6, 9 ein signifikantes Signalbild aus einer x- ,y- und z-Größe. Die jeweiligen Werte für die magnetische Fußdichte sind als x-Wert 20, y-Wert 21 und z-Wert 22 angegeben.The closure monitoring 13 is now to provide a signal depending on the switching state of the drive rods 4, 6, 9, which is significant for the respective switching position. For this purpose, the arrangement provides a sensor which detects the change in the earth's magnetic field by the drive rod element and which is associated with an evaluation unit which assigns the change to a switching position. A measurable disturbance and thus a change in the earth's magnetic field can already take place through the drive rod 6 itself, which causes a significant change in magnetic field through bores, cranks and components attached thereto when it is displaced. Therefore, the shutter monitor 13 does not need a special detector, which contributes to the signal generation. The sensor used is for example an Xtrinsic MAG3110 Three-Axis, Digital Magnetometer from the company freescale xtrinsic. Depending on the relative position of the drive rod 6, 9, this sensor supplies a characteristic signal, which is shown by way of example in FIG Fig. 4 is shown. Each of the three spatial axes is output with its own signal. This results for each position of the drive rods 6, 9 a significant signal image of an x, y and z size. The respective values for the magnetic base density are indicated as x value 20, y value 21 and z value 22.

In der Kippöffnungsstellung 19 ist der vom Sensor bereitgestellte x-Wert 20 deutlich höher als der z-Wert 22, der über dem Y-Wert 21 liegt. Das Einstellen der Drehöffnungsstellung 16 bewirkt neben einer Absenkung des X-Wertes 20 auch einen stark abfallenden z-Wert 22 und einen geringfügig ansteigenden y-Wert 21. In der Verschlussstellung 14 sinkt der x-Wert 20 weiter ab und der z-Wert 22 maximiert sich bei einer Steigerung des Y-Wertes 21.In the tilt open position 19, the x value 20 provided by the sensor is significantly higher than the z value 22, which is above the Y value 21. The setting of the rotational opening position 16 causes not only a lowering of the X value 20 but also a sharply decreasing z value 22 and a slightly increasing y value 21. In the closed position 14, the x value 20 decreases further and the z value 22 maximizes with an increase of the Y-value 21.

Jede der Schaltstellung weist daher nicht nur einen signifikanten x-, y- und z-Wert 20, 21, 22 auf, sondern auch ein bestimmtes Muster dieser Werte, was eine Manipulation unmöglich macht, da alle drei Werte in einer bestimmten Größe beeinflusst werden müssen.Each switch position therefore has not only a significant x, y and z value 20, 21, 22, but also a particular pattern of these values, which makes manipulation impossible, since all three values must be influenced in a particular size ,

Die Verarbeitung der vom Sensor 23 ausgegeben Signale erfolgt in der, im Schaubild nach Fig. 5 skizierten Weise. Das vom Sensor 23 bereit gestellte Signal in Form der x-, y- und z-Werte 20, 21, 22 wird einer Auswerteeinheit 24 zugeführt. Die Auswerteeinheit 24 vergleicht die x-, y- und z-Werte 20, 21, 22 mit zuvor in Bezug auf die Schaltstellungen 14, 16,19 des Treibstangenelementes 6,9 relativ zum Sensor 23 gespeicherten Referenzwerte und ordnet eine Schaltstellung zu. Diese wird an ein Kommunikationsmodul 25 übergeben, welches die ermittelte Schaltstellung an eine nicht dargestellte Anzeigeeinheit oder Alarmanlage überträgt. Dies erfolgt bevorzugt drahtlos, um einen Verkabelungsaufwand gering zu halten. Die Auswerteeinheit 24 ist dabei vorzugsweise Mikroprozessor gesteuert und weist einen nichtflüchtigen Speicher auf. Der nichtflüchtige Speicher kann neben der Speicherung der Referenzwerte auch Betätigungszeitpunkte und -Anzahl speichern.The processing of the signals output by the sensor 23 takes place in the, in the diagram after Fig. 5 skied way. The signal provided by the sensor 23 in the form of the x, y and z values 20, 21, 22 is supplied to an evaluation unit 24. The evaluation unit 24 compares the x, y and z values 20, 21, 22 with reference values previously stored relative to the switching positions 14, 16, 19 of the drive rod element 6, 9 relative to the sensor 23 and assigns a switching position. This is transferred to a communication module 25, which transmits the determined switching position to a display unit or alarm system, not shown. This is preferably done wirelessly to keep cabling costs low. The evaluation unit 24 is preferably microprocessor-controlled and has a nonvolatile memory. The nonvolatile memory can save not only the storage of the reference values but also the actuation times and the number of times.

Um Energie zu sparen ist vorgesehen, dass der Sensor 23 Ist-Werte 20, 21, 22 in zyklischen Abständen mit den hinterlegten Referenzwerten vergleicht.
Das Verfahren zur Inbetriebnahme der Anordnung sieht dabei einen Referenzierungslauf für die Auswerteinheit 24 vor, in dem sich das Treibstangenelement 6, 9 in Öffnungsstellung befindet und der Messwert des Sensors 23 ermittelt wird. Dieser Vorgang wird für jede über den Treibstangenbeschlag einstellbare Schaltstellung wiederholt.In order to save energy, it is provided that the sensor 23 compares actual values 20, 21, 22 at cyclic intervals with the stored reference values.
The method for starting up the arrangement provides for a referencing run for the evaluation unit 24, in which the drive rod element 6, 9 is in the open position and the measured value of the sensor 23 is determined. This procedure is repeated for each shift position adjustable via the espagnolette fitting.

Um eine missbräuchliche Beeinflussung des Sensors 23 zu vermeiden ist vorgesehen, dass bei, von den ermittelten Referenzwerten abweichenden Signalen, ein Alarm ausgelöst wird.In order to avoid an abusive influencing of the sensor 23, it is provided that an alarm is triggered in the case of signals deviating from the determined reference values.

Die Anordnung kann auch den in Fig. 2 dargestellten Aufbau haben, bei dem die Verschlussüberwachung 13 an einem Deckwinkel 11 eines am Flügel 28 befestigten Treibstangenbeschlagbauteils 1 angeordnet ist und der Sensor 23 innerhalb des Gehäuses 26 in Richtung des Riegelelementes 15 weist. Da die Verschlussüberwachung 13 das Signal aus der Gesamtbeeinflussung aller das Magnetfeld-beeinflussenden Bauteile generiert, wirken hier Treibstangen und Riegelelemente gleichermaßen und es ist unerheblich, ob die Verschlussüberwachung horizontal oder vertikal angeordnet ist.The arrangement can also be found in Fig. 2 have shown structure in which the closure monitoring 13 is disposed at a cover angle 11 of a fixed to the wing 28 espagnolette fitting 1 and the sensor 23 has within the housing 26 in the direction of the locking element 15. Since the shutter monitoring 13 generates the signal from the total influence of all the magnetic field-influencing components, here drive rods and locking elements act equally and it is irrelevant whether the shutter monitoring is arranged horizontally or vertically.

Bei dem in Fig. 3 dargestellten Ausführungsbeispiel ist die Verschlussüberwachung am Rahmen 27 angebracht, während der Flügel 28 das Treibstangenbeschlagbauteil 1 trägt.At the in Fig. 3 illustrated embodiment, the closure monitoring on Frame 27 mounted while the wing 28 carries the drive rod fitting component 1.

Die Verwendung eines Magnetfeldsensors zur Erfassung von Magnetfeldänderungen an einem Verriegelungselement einer Verriegelungsvorrichtung des Fensters, bei dem der Magnetfeldsensor einem Treibstangenelement 1 zugeordnet ist erlaubt es die Schaltstellungen zuverlässig zu detektieren.The use of a magnetic field sensor for detecting magnetic field changes to a locking element of a locking device of the window, in which the magnetic field sensor is assigned to an espagnolette element 1 allows the switch positions to be reliably detected.
