Description
Die vorliegende Erfindung betrifft einen elektrisch auslösbaren Tür- bzw. Fensteröffner mit einem Gehäuse, einer im Gehäuse angeordneten Öffnerfalle, sowie zumindest einer Einheit zur Erkennung zumindest einer Anwesenheit eines Riegels in einer Verriegelungsstellung eines mit dem Tür- bzw. Fensteröffner zusammenwirkenden Tür- bzw. Fensterschlosses. Ferner betrifft die vorliegende Erfindung eine Tür- bzw. Fensterschließanlage umfassend ein Tür- bzw. Fensterschloss und einen Tür- bzw. Fensteröffner.The present invention relates to an electrically triggerable door or window opener having a housing, an opener trap arranged in the housing, and at least one unit for detecting at least one presence of a bolt in a locking position of a door or window lock cooperating with the door or window opener , Furthermore, the present invention relates to a door or window locking system comprising a door lock and a door or window opener.
Elektrisch auslösbare Tür- bzw. Fensteröffner sind allgemein bekannt und werden meistens im Tür- bzw. Fensterrahmen gegenüber einem im Tür- bzw. Fensterflügel eingebauten Einsteck-Riegel-Fallen-Schloss eingebaut. Grundsätzlich können sie jedoch auch in einem, dem mit dem Einsteckschloss versehenen Tür- bzw. Fensterblatt gegenüberliegenden, Tür- bzw. Fensterflügel vorgesehen sein. Dabei greift die Schlossfalle des im betreffenden Türblatt bzw. Fenster eingebauten Einsteckschlosses bei geschlossener Tür bzw. Fenster in den als Öffnerfalle bezeichneten federnd vorgespannten Drehkörper des Tür- bzw. Fensteröffners.Electrically triggered door or window openers are well known and are usually installed in the door or window frame against a built-in door or window sash-latch trap locks. In principle, however, they can also be provided in a door or window wing opposite the door or window leaf provided with the mortise lock. In this case, the latch of the built-in door leaf or window mortise lock engages in the closed door or window in the called normally closed case spring-biased rotary body of the door or window opener.
Zur Überwachung der Verriegelung von Türen bzw. Fenstern welche z.B. Einsteck-Riegel-Fallen-Schlösser aufweisen, werden bekannte Riegelschaltkontakte vorgesehen, die Meldungen über den Verriegelungszustand an Alarmanlagen, Gebäudeüberwachungssysteme, Tableaus, usw. liefern können. Solch separate, mechanische Riegelschaltkontakte haben einen relativ großen Platzbedarf und übertragen die Meldungen mittels eines bewegbaren Kabels an eine Kontrolleinrichtung. Dies hat den Nachteil, dass bei einem Kabelbruch der Verriegelungszustand bzw. die Riegelposition eines Tür- bzw.

This has the disadvantage that in case of a cable break the Locking state or the locking position of a door or window lock can not be communicated.
Aufgabe der vorliegenden Erfindung ist es, einen Tür- bzw. Fensteröffner zu schaffen, der eine Überwachung der Verriegelung von Türen bzw. Fenstern bei gleichzeitiger Minimierung des Platzbedarfs des Tür- bzw. Fensteröffners ermöglicht und einen Kabelbruch vermeidet.Object of the present invention is to provide a door or window opener, which allows monitoring of the locking of doors or windows while minimizing the space requirement of the door or window opener and avoids cable breakage.
Diese Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Weitere vorteilhafte Ausbildungen der Erfindung sind den Unteransprüchen, der folgenden Beschreibung und den Zeichnungen entnehmbar.This object is solved by the subject matter of claim 1. Further advantageous embodiments of the invention are the dependent claims, the following description and the drawings removed.
Ein erfindungsgemäßer Tür- bzw. Fensteröffner umfasst ein Gehäuse, eine im Gehäuse angeordnete Öffnerfalle, sowie zumindest eine Einheit zur Erkennung zumindest einer Anwesenheit eines Riegels in einer Verriegelungsstellung eines mit dem Tür- bzw. Fensteröffner zusammenwirkenden Tür- bzw. Fensterschlosses. Die Erfindung zeichnet sich dadurch aus, dass die zumindest eine Einheit zumindest einen kontaktlosen Sensor aufweist und dass die zumindest eine Einheit im oder am Gehäuse angeordnet ist.An inventive door or window opener comprises a housing, an opener trap arranged in the housing, and at least one unit for detecting at least one presence of a bolt in a locking position of a door or window lock cooperating with the door or window opener. The invention is characterized in that the at least one unit has at least one contactless sensor and that the at least one unit is arranged in or on the housing.
Ein kontaktloser Sensor weist in der Regel keine beweglichen Bauteile auf, die im Gebrauch verschlissen oder gar defekt werden können.A contactless sensor usually has no moving parts that can become worn or even broken in use.
Ferner sind solch kontaktlose Sensoren relativ klein, dies bedeutet, dass der Platzbedarf eines solchen Bauteils im Vergleich zu einem mechanischen Sensor reduziert ist. Dieser reduzierte Platzbedarf ermöglicht sogar die Unterbringung des Sensors bzw. einer Einheit, die diesen Sensor umfasst, im oder am Gehäuse des Tür- bzw. Fensteröffners.Furthermore, such contactless sensors are relatively small, which means that the space requirement of such a component is reduced compared to a mechanical sensor. This reduced space requirement even allows the accommodation of the sensor or a unit comprising this sensor, in or on the housing of the door or window opener.
Vorteilhafterweise ist der kontaktlose Sensor eine kostengünstige und platzsparende Sensor-Reflexlichtschranke bzw. ein Infrarotsensor bzw. ein Radarsensor bzw. ein Infrarotsensor bzw. ein Magnetfeldsensor oder dergleichen.Advantageously, the contactless sensor is a cost-effective and space-saving sensor reflex light barrier or an infrared sensor or a radar sensor or an infrared sensor or a magnetic field sensor or the like.
Bevorzugt ist die zumindest eine Einheit im Bereich der Öffnerfalle angeordnet. Der Riegel eines mit dem Tür- bzw. Fensteröffner zusammenwirkenden Tür- bzw. Fensterschlosses ist in der Regel oberhalb bzw. unterhalb der Schlossfalle angeordnet. Durch die Anordnung der zumindest einen Einheit im Bereich der Öffnerfalle ist diese zugleich im Bereich des Riegels angeordnet und ermöglicht einen noch kompakteren Aufbau des Tür- bzw. Fensteröffners.Preferably, the at least one unit is arranged in the region of the Öffnerfalle. The bolt of a cooperating with the door or window opener door or window lock is usually arranged above or below the lock latch. Due to the arrangement of the at least one unit in the region of the opener trap, this is at the same time arranged in the region of the bolt and allows an even more compact construction of the door or window opener.
Insbesondere ist die zumindest eine Einheit im Gehäuse angeordnet und ein Blickfeld des zumindest einen kontaktlosen Sensors ist aus dem Gehäuse nach außen gerichtet. Somit sind keine weiteren Komponenten zwischen dem Tür- bzw. Fensteröffner und dem Riegel angeordnet, sodass Fehlbestimmungen über die Anwesenheit des Riegels in einer Verriegelungsstellung vermieden werden können.In particular, the at least one unit is arranged in the housing and a field of view of the at least one contactless sensor is directed out of the housing to the outside. Thus, no other components between the door or window opener and the bolt are arranged so that misjudgments can be avoided by the presence of the bolt in a locked position.
Besonders bevorzugt ist der kontaktlose Sensor auf einer Platine im Gehäuse angeordnet, wobei die Platine vorzugsweise auch an die Öffnerfalle bzw. an Komponenten der Öffnerfalle elektrisch angeschlossen ist. Zumindest ein Teil der elektrischen Komponenten der Einheit ist somit im Gehäuse des Tür- bzw. Fensteröffners angeordnet. Dies bietet einen Schutz vor mechanischem Verschleiß dieser Komponenten. Ferner können elektrische Komponenten eines bevorzugt elektrisch auslösbaren Tür- bzw. Fensteröffners ebenfalls auf dieser Platine angeordnet werden, was den Platzbedarf für elektrische Komponenten innerhalb des Gehäuses weiter reduziert.Particularly preferably, the contactless sensor is arranged on a circuit board in the housing, wherein the circuit board is preferably also electrically connected to the Öffnerfalle or to components of the Öffnerfalle. At least a part of the electrical components of the unit is thus arranged in the housing of the door or window opener. This provides protection against mechanical wear of these components. Furthermore, electrical components of a preferably electrically triggerable door or window opener can also be arranged on this board, which further reduces the space requirement for electrical components within the housing.
Vorteilhafterweise ist der kontaktlose Sensor mittels einer Schnittstelle, z.B. einem Master-Slave-Bus, vorzugsweise einer I2C-Schnittstelle, auf der Platine an einen Mikrokontroller angeschlossen. Die Anordnung eines Mikrokontrollers auf der Platine ermöglicht kurze Signalwege und somit keine längeren Verzögerungen beim Erkennen einer Anwesenheit des Riegels in einer Verriegelungsstellung. Die Verwendung einer solchen Schnittstelle ermöglicht eine verbesserte Konnektivität des Sensors zum Mikrokontroller und ermöglicht das Anschließen von mehreren Sensoren an einem Bus gleichzeitig.Advantageously, the contactless sensor is connected by means of an interface, for example a master-slave bus, preferably an I 2 C interface, on the board to a microcontroller. The arrangement of a microcontroller on the board allows short signal paths and thus no longer delays in detecting a presence of the bolt in a locked position. The use of such an interface allows for improved connectivity of the sensor to the microcontroller and allows multiple sensors to be connected to a bus simultaneously.
Besonders bevorzugt ist der Mikrokontroller dazu ausgebildet, zumindest Signale des kontaktlosen Sensors zu verarbeiten. Somit wird ein Tür- bzw. Fensteröffner geschaffen der Signale über eine Anwesenheit des Riegels in einer Verriegelungsstellung direkt ausgeben kann.Particularly preferably, the microcontroller is designed to process at least signals of the contactless sensor. Thus, a door or window opener is created which can output signals about a presence of the bolt in a locked position directly.
Insbesondere ist/sind der kontaktlose Sensor und/oder der Mikrokontroller an einen Brückengleichrichter auf der Platine angeschlossen. Eine am Tür- bzw. Fensteröffner bereitgestellte Wechselspannung kann folglich innerhalb des Tür- bzw. Fensteröffners in eine Gleichspannung gewünschter Stärke umgewandelt werden.In particular, the contactless sensor and / or the microcontroller are / are connected to a bridge rectifier on the board. An AC voltage provided to the door or window opener can thus be converted within the door or window opener into a DC voltage of desired strength.
Vorzugsweise sind weitere Sensoren an die Platine bzw. den Mikrokontroller anschließbar. Solch weitere Sensoren können z.B. einen Näherungssensor umfassen. Bei Erkennen einer Annäherung einer Person bei nicht verriegeltem Tür- bzw. Fensterschloss mittels eines Näherungssensors kann der Tür- bzw. Fensteröffner beispielsweise eine Entriegelung der Öffnerfalle erlauben und somit der Person einen Durchtritt durch die überwachte Tür ermöglichen.Preferably, further sensors can be connected to the circuit board or the microcontroller. Such further sensors may e.g. include a proximity sensor. Upon detection of an approach of a person with unlocked door or window lock by means of a proximity sensor, the door or window opener, for example, allow unlocking the Öffnerfalle and thus allow the person to pass through the monitored door.
Vorteilhafterweise erkennt die Software automatisch die Anzahl der angeschlossenen Sensoren an dem Mikrokontroller bzw. an der Platine.Advantageously, the software automatically detects the number of connected sensors on the microcontroller or on the board.
Bevorzugt sind zwei kontaktlose Sensoren im Gehäuse vorgesehen, wobei ein erster Sensor oberhalb und ein zweiter Sensor unterhalb der Öffnerfalle angeordnet ist. Durch die Bereitstellung von zwei Sensoren kann der Tür- bzw. Fensteröffner in beiden DIN-Richtungen verwendet werden.Preferably, two contactless sensors are provided in the housing, wherein a first sensor above and a second sensor is disposed below the Öffnerfalle. By providing two sensors, the door or window opener can be used in both DIN directions.
Vorteilhafterweise ist ein Schalter vorgesehen, mittels welchem einer der zwei kontaktlosen Sensoren zur Verwendung auswählbar ist, wobei bevorzugt der Schalter auf der Platine und/oder in dem oder am Gehäuse angeordnet ist oder durch eine Funktion des Mikrokontrollers bereitgestellt wird. Solch ein Schalter oder eine Funktion erlaubt die Einstellung des Tür- bzw. Fensteröffners vor oder während dessen Einbau, sodass der Tür- bzw. Fensteröffner im Zustand DIN rechts bzw. DIN links verwendet werden kann. Ferner kann durch die Verwendung des Schalters eine Stromversorgung zum nicht verwendeten Sensor bzw. einer nicht verwendeten Einheit unterbunden werden, sodass der Stromverbrauch reduziert werden kann.Advantageously, a switch is provided, by means of which one of the two contactless sensors is selectable for use, wherein preferably the switch is arranged on the circuit board and / or in or on the housing or is provided by a function of the microcontroller. Such a switch or function allows the setting of the door or window opener before or during its installation, so that the door or window opener can be used in the state DIN right or DIN left. Further, by using the switch, a power supply to the unused sensor or an unused unit can be suppressed, so that the power consumption can be reduced.
Insbesondere ist das Gehäuse an einem Beschlag befestigt, welcher zwei Aussparungen für den Riegel des mit dem Tür- bzw. Fensteröffner zusammenwirkenden Tür- bzw. Fensterschlosses aufweist. Ein Beschlag ermöglicht die einfache Unterbringung sowie Anbindung des Tür- bzw. Fensteröffners in einem Tür- bzw. Fensterrahmen bzw. einer Tür bzw. einem Fenster.In particular, the housing is fastened to a fitting which has two recesses for the latch of the door or window lock cooperating with the door or window opener. A fitting allows easy accommodation and connection of the door or window opener in a door or window frame or a door or a window.
Besonders bevorzugt ist jeweils ein kontaktloser Sensor einer Aussparung zugeordnet und dazu ausgebildet, einen Raum benachbart der jeweiligen Aussparung zu überwachen, um die Anwesenheit des Riegels in der Verriegelungsstellung in diesem Raum zu erkennen, vorzugsweise wobei ein Blickfeld des kontaktlosen Sensors auf den jeweiligen Raum gerichtet ist. Der Beschlag definiert somit zusätzlich zumindest eine Grenzfläche des Blickfelds eines Sensors in Richtung des Tür- bzw. Fensterschlosses. Hierbei wird dieses Blickfeld in seiner Größe reduziert, was zu einer Verringerung eines Datenstroms eines kontaktlosen Sensors führt.Particularly preferably, in each case a contactless sensor is associated with a recess and designed to monitor a space adjacent to the respective recess in order to detect the presence of the bolt in the locking position in this space, preferably with a field of view of the contactless sensor directed at the respective space , The fitting thus additionally defines at least one interface of the field of view of a sensor in the direction of the door or window lock. In this case, this field of view is reduced in size, which leads to a reduction of a data stream of a contactless sensor.
Insbesondere ist eine weitere Schnittstelle im bzw. am Gehäuse vorgesehen, mittels derer eine Kommunikation zwischen dem Tür- bzw. Fensteröffner und einer Kontrolleinrichtung einer Überwachungsanlage ermöglicht wird, vorzugsweise wobei bei Erkennen einer Anwesenheit des Riegels in der Verriegelungsstellung ein Überwachungsmodus der Kontrolleinrichtung aktiv schaltbar ist. Die mittels des Sensors erhaltenen Signale bzw. Daten über den Verriegelungszustand können mittels der Schnittstelle demgemäß an eine Überwachungsanlage weitergeleitet werden, umgekehrt können mittels der Schnittstelle auch Signale bzw. Daten von der Überwachungsanlage an den Tür- bzw. Fensteröffner übertragen werden.In particular, a further interface is provided in or on the housing, by means of which a communication between the door or window opener and a control device of a surveillance system is made possible, preferably wherein upon detection of a presence of the bolt in the locking position, a monitoring mode of the control device is actively switchable. The signals received via the sensor or data on the locking state can be forwarded accordingly by means of the interface to a monitoring system, conversely, signals or data can be transmitted from the monitoring system to the door or window opener by means of the interface.
In einem weiteren Aspekt betrifft die vorliegende Erfindung eine Tür- bzw. Fensterschließanlage, die ein Tür- bzw. Fensterschloss mit einem Riegel und einen erfindungsgemäßen Tür- bzw. Fensteröffner umfasst.In a further aspect, the present invention relates to a door or window locking system comprising a door or window lock with a bolt and a door or window opener according to the invention.
Die Vorteile, die im Zusammenhang mit dem Tür- bzw. Fensteröffner erläutert wurden, gelten sinngemäß für die Tür- bzw. Fensterschließanlage.The advantages explained in connection with the door or window opener apply mutatis mutandis to the door or window locking system.
