Description

Zustandsdetektionsvorrichtung für eine eine Schließeinrichtung zur Verriegelung eines Flügels in einem Rahmen aufweisende Tür oder dergleichen mit einem zur auf dem Rahmen gerichteten Montage vorgesehenen Befestigungsmittel zur Halterung der Schließeinrichtung, mit einer Sensoreinheit zur Erfassung des geschlossenen Zustands der Tür, wobei das Befestigungsmittel zumindest teilweise für Signale der Sensoreinheit durchlässig gestaltet ist, die Sensoreinheit vor dem in die Schließeinrichtung hineinragenden Ende des Befestigungsmittels in der Schließeinrichtung angeordnet ist und das Befestigungsmittel rohrförmig gestaltet ist.A door or the like having a door or the like having a frame-mounted fastener for holding the latch, a sensor unit for detecting the closed state of the door, the fastener being at least partly for signals of the door Sensor unit is designed to be permeable, the sensor unit is arranged in front of the protruding into the closing device end of the fastening means in the locking device and the fastening means is tubular.

Eine solche Zustandsdetektionsvorrichtung ist aus der US 2008/012705 A1 bekannt. Hierbei handelt es sich um eine Zustandsdetektionsvorrichtung, welche mit einem magnetischen Schalter, welcher am Türblatt angeordnet ist, arbeitet. Dieser Schalter wechselwirkt mit einem magnetischen Feld, das durch einen am Türrahmen befestigten Magneten erzeugt wird. Die Türzustandsdetektionsvorrichtung ist dabei zur Montage in einem Befestigungsmittel der Schließeinrichtung vorgesehen und das Befestigungsmittel ist zumindest teilweise für Signale der Sensoreinheit durchlässig gestaltet.Such a state detection device is known from US 2008/012705 A1 known. This is a state detection device which operates with a magnetic switch located on the door leaf. This switch interacts with a magnetic field generated by a magnet attached to the door frame. The door state detection device is provided for mounting in a fastening means of the closing device and the fastening means is at least partially designed to be permeable to signals of the sensor unit.

Eine solche Zustandsdetektionsvorrichtung weiterhin ist aus der DE 10 2010 018 566 B4 bekannt. Bei dieser Zustandsdetektionsvorrichtung dient das Befestigungsmittel zur Verschraubung einer Schließeinrichtung mit einem Flügel. Innerhalb des Befestigungsmittels ist eine Sensoreinheit zur Erfassung eines geschlossenen Zustandes der Tür angeordnet.Such a state detection device is further known from the DE 10 2010 018 566 B4 known. In this state detection device, the fastening means is used for screwing a locking device with a wing. Within the fastening means, a sensor unit for detecting a closed state of the door is arranged.

Nachteilig bei dieser Zustandsdetektionsvorrichtung ist jedoch, dass das Befestigungsmittel abhängig ist von den Schlossmaßen der Schließeinrichtung. Daher erfordert diese Gestaltung eine sehr aufwändige Bevorratung von unterschiedlichen Einheiten der Sensoreinheit mit dem Befestigungsmittel. Weiterhin ist das Befestigungsmittel mit der Sensoreinheit starken Einflüssen aus der Umgebung ausgesetzt, da z.B. eine Übertragungsstrecke für Daten und Energie zwischen Schließeinrichtung und Befestigungsmittel erforderlich wird.A disadvantage of this condition detection device, however, is that the fastening means is dependent on the lock dimensions of the locking device. Therefore, this design requires a very expensive storage of different units of the sensor unit with the fastening means. Furthermore, the fastening means with the sensor unit is exposed to strong influences from the environment, since, for example, a transmission path for data and energy between locking device and fastening means is required.

Der Erfindung liegt das Problem zugrunde, eine Zustandsdetektionsvorrichtung der eingangs genannten Art so weiter zu bilden, dass sie besonders kostengünstig herstellbar und zuverlässig ist.The invention is based on the problem to further develop a state detection device of the type mentioned so that it is particularly inexpensive to produce and reliable.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass die Sensoreinheit ein dem freien Ende des Befestigungsmittels gegenüberstehend im Rahmen anzuordnendes Reflektorelement hat und in der Schließeinrichtung vor dem anderen Ende des Befestigungsmittels eine Leuchtdiode zur Abstrahlung von Licht und eine Fotozelle zum Empfang des von dem Reflektorelement reflektierten Lichts hat.This problem is inventively solved in that the sensor unit has a reflector element to be arranged opposite the free end of the fastening means and in the locking device in front of the other end of the fastening means has a light emitting diode for emitting light and a photocell for receiving the reflected light from the reflector element ,

Durch diese Gestaltung vermag die Sensoreinheit zuverlässig zu detektieren, ob der Flügel im Rahmen liegt. Vorzugsweise ist das Reflektorelement auf einem im Rahmen anzuordnenden Schließblech befestigt.With this design, the sensor unit can reliably detect whether the wing is in the frame. Preferably, the reflector element is mounted on a locking plate to be arranged in the frame.

Manipulationsversuche lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung weitgehend vermeiden, wenn das Reflektorelement eine definierte Polarisationscharakteristik oder Reflexionscharakteristik hat und die Sensoreinheit Mittel zur Auswertung der Charakteristik der Reflexionen des Reflektorelements hat. Eine definierte Reflexionscharakteristik ist z.B. frequenzselektiv oder durch die Polarisationsrichtung beeinflusst. Durch diese Gestaltung lässt sich das Reflektorelement mit einer vorgesehenen Orientierung, einer spezifischen Wellenlänge oder einem Muster der Reflektionen ausbilden. Alternativ kann das Reflektorelement auch den Bereich der Wellenlänge verschieben. Ebenso kann die Sensoreinheit einen definierten Pulsbetrieb aufweisen. Die spezifische Wellenlänge kann im sichtbaren Licht oder im Ultraviolett oder Infrarotbereich liegen. Die hierzu angepasste Sensoreinheit erfasst, ob die Lichtstrahlen von dem Reflektor kommen oder der Umgebung oder einem Manipulationsversuch, z.B. durch Einbringen eines Polarisationsfilters. Damit wird zudem der Einfluss von Lichtreflexen aus der Umgebung gering gehalten. Die Mittel zur Auswertung der Charakteristik der Reflexionen können eine mit der Fotozelle verbundene Auswerteelektronik sein.According to another advantageous development of the invention, manipulation attempts can be largely avoided if the reflector element has a defined polarization characteristic or reflection characteristic and the sensor unit has means for evaluating the characteristic of the reflections of the reflector element. A defined reflection characteristic is eg frequency-selective or influenced by the polarization direction. With this configuration, the reflector element can be formed with an intended orientation, a specific wavelength or a pattern of the reflections. Alternatively, the reflector element can also shift the range of the wavelength. Likewise, the sensor unit may have a defined pulse operation. The specific wavelength may be in visible light or in the ultraviolet or infrared range. The adapted thereto sensor unit detects whether the light rays come from the reflector or the environment or a manipulation attempt, for example by introducing a polarizing filter. This will be In addition, the influence of light reflections from the environment kept low. The means for evaluating the characteristic of the reflections may be an evaluation electronics connected to the photocell.

Die Zustandsdetektionsvorrichtung ermöglicht gemäß einer anderen vorteilhaften Weiterbildung der Erfindung insbesondere bei elektronischen oder teilelektronischen Schließzylindern einen besonders zuverlässigen Betrieb, wenn die Schließeinrichtung einen Schließzylinder, insbesondere einen Schließzylinder mit einem elektronischen Sperrmechanismus hat und wenn die Sensoreinheit in dem Schließzylinder angeordnet ist. Ein weiterer Vorteil dieser Gestaltung besteht darin, dass die Zustandsdetektionsvorrichtung automatisch mit dem Schließzylinder montiert ist. Weitere bauliche Anpassungen sind nicht erforderlich. Die Auswerteelektronik zur Auswertung der Signale der Fotozelle ist vorzugsweise Teil einer Steuerelektronik des Schließzylinders.The state detection device according to another advantageous embodiment of the invention, especially in electronic or semi-electronic lock cylinders particularly reliable operation when the locking device has a lock cylinder, in particular a lock cylinder with an electronic locking mechanism and when the sensor unit is arranged in the lock cylinder. Another advantage of this design is that the condition detection device is automatically mounted with the lock cylinder. Further structural adjustments are not required. The transmitter for evaluating the signals of the photocell is preferably part of an electronic control of the lock cylinder.

Durch eine weitere Ausgestaltung werden Manipulationsversuche besonders gut erkannt, wenn die Sensoreinheit Mittel zur Bestimmung der Laufzeit der optischen Strahlung hat. Es kommt vorzugsweise eine lichtaussendende Diode zum Einsatz, die Laserstrahlung aussendet. Es erfolgte eine Auswertung der Laufzeit des Lichts oder eine Auswertung der Phasenlage.By a further embodiment manipulation attempts are particularly well recognized when the sensor unit has means for determining the duration of the optical radiation. It is preferably a light-emitting diode is used, which emits laser radiation. There was an evaluation of the duration of the light or an evaluation of the phase position.

Eine weitere bevorzugte Ausgestaltung zur Erkennung von Manipulationsversuchen sieht vor, dass die Sensoreinheit Mittel zur Bestimmung der Phasenlage von emittierter und reflektierter Strahlung hat.A further preferred embodiment for the detection of manipulation attempts provides that the sensor unit has means for determining the phase position of emitted and reflected radiation.

Eine mechanische Schwächung des Schließzylinders im Bereich des Befestigungsmittels lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung weitgehend vermeiden, wenn der Schließzylinder in der Aufnahme für das Befestigungsmittel eine Umlenkeinheit zur Umlenkung der Signale der Sensoreinheit hat. Die Umlenkeinheit kann wie das zuvor beschriebene Reflektorelement eine definierte Polarisationscharakteristik aufweisen. Die Zustandsdetektionsvorrichtung ermöglicht gemäß einer anderen vorteilhaften Weiterbildung der Erfindung eine besonders einfache zentrale Überwachung des im Rahmen liegenden Flügels, wenn die Schließeinrichtung ein Schloss mit einer Schließzylinderaufnahme aufweist und wenn die Sensoreinheit in dem Schloss angeordnet ist. Diese Gestaltung ist insbesondere bei Schließanlagen mit mehreren Türen von Vorteil.A mechanical weakening of the lock cylinder in the region of the fastener can be largely avoided according to another advantageous embodiment of the invention, when the lock cylinder has a deflection unit for deflecting the signals of the sensor unit in the receptacle for the fastener. The deflection unit, like the previously described reflector element, can have a defined polarization characteristic. The state detection device according to another advantageous embodiment of the invention allows a particularly simple central monitoring of the wing lying in the frame when the locking device has a lock with a lock cylinder receptacle and when the sensor unit is arranged in the lock. This design is particularly advantageous for locking systems with multiple doors.

Das Befestigungsmittel mit den zwei teleskopartig miteinander verschraubten Hohlschrauben lässt sich gemäß einer weiteren vorteilhaften Weiterbildung der Erfindung besonders einfach von der Schließeinrichtung lösen, wenn das Befestigungsmittel mit den zwei teleskopartig miteinander verschraubten Hohlschrauben eine Hemmung der Bewegung in Löserichtung aufweist. Das Befestigungsmittel lässt sich dadurch jederzeit sicher als gesamte Einheit von der Schließeinrichtung entfernen und aus dem Rahmen, bzw. dem Flügel führen.The fastening means with the two telescopically screwed hollow screws can be particularly easily solved by the locking device according to a further advantageous embodiment of the invention, when the fastening means with the two telescopically screwed together hollow screws has an inhibition of movement in the release direction. The fastener can be safely removed at any time as a whole unit of the locking device and out of the frame, or the wing.
