Definitions
- the invention relates to a system for securing a wing of a door, a window or the like with a blocking device for locking, i.e. preventing the fixing of a wing of a door, a window or the like that can be locked via a locking device, with a device that can be actuated in particular by an electric motor and/or electromagnetically , Controllable via a control device lock.
- a hold-open system is a device for keeping fire closures open, in particular fire protection doors, smoke protection doors and/or the like. It ensures that fire protection closures or smoke closures are kept open, but close securely in the event of a fire or if smoke develops.
- hold-open systems which constantly keep an open fire protection door open against the spring force of a mechanical memory of a drive. In the event of a fire, the hold-open system is triggered, causing the door to close using the spring force of the mechanical memory.
- the hold-open system generally includes an electrical power supply, a hold-open device, a triggering device and a fire detection system.
- the mechanical energy store can, for example, include a spring unit that is manual opening of the door leaf is tensioned and released again when the door leaf is closed.
- a quiescent current locking device based on an arrangement comprising a permanent magnet and one or more coils has already been proposed for locking a leaf of a door, a window or the like.
- the vane can be locked by the permanent magnet when the coil is not energized, while the locking can be triggered by energizing the coil to compensate for the magnetic field of the permanent magnet.
- a door holding magnet provided on the wall or on the door leaf with integrated coils can interact with an anchor plate mounted on the door leaf.
- an electromechanical locking device integrated in a slide rail in which a sliding block guided in the slide rail can be fixed directly or via a mechanical transmission by means of a permanent magnet. The arrangement in question does not have to be firmly connected to the door leaf (free swing).
- the door leaf is opened on a door with an associated drive or door closer, potential energy is loaded into the spring unit of the drive or door closer. For example, if the anchor plate of a locking device with an anchor plate reaches the permanent magnet, this holds the anchor plate against the closing force of the drive or door closer.
- one or more coils can be energized to compensate for the magnetic field of the permanent magnet. Due to the potential energy stored in the door closer, the anchor plate moves away from the permanent magnet with the door leaf, whereupon the door closer closes the door leaf. As soon as the armature plate is sufficiently far away from the permanent magnet, the current through the at least one coil is switched off again.
- Such a quiescent current locking device has the significant advantage over conventional locking devices working according to the working current principle that electrical energy is only required for the relatively short time of triggering the locking device.
- the redundancy can be monitored. If one redundancy branch fails, the locking device can be triggered via another redundancy branch, after which the door leaf can close.
- a locked current locking device has the particular disadvantage that it can no longer be triggered in the event of an alarm if the door leaf is opened after a failure of the last redundancy branch and the anchor plate reaches the permanent magnet. There is then also no longer any possibility of triggering the determination via a redundancy branch.
- EP3064692A1 discloses an example of a system for detecting a door leaf.
- the invention is based on the object of specifying a hold-open system of the type mentioned at the outset, in which the aforementioned problems are eliminated.
- the system according to the invention with a device for blocking the locking of a leaf of a door, a window or the like that can be locked via a locking device comprises a lock that can be actuated in particular by an electric motor and/or electromagnetically and can be controlled via a control device.
- the control device is designed with one or more redundancies, the lock being able to be controlled via a corresponding number of redundancy branches and the operability of the various redundancy branches being able to be monitored via the control device in each case.
- the functionality of a respective redundancy branch can preferably be monitored by the control device continuously or at definable time intervals.
- control device of the blocking device comprises at least two redundant control channels each assigned to a redundancy branch.
- one of its own, in particular electromotive and/or electromagnetic, actuating devices, assigned to the relevant redundancy branch, can advantageously be controlled in order to actuate the lock.
- actuating devices assigned to the relevant redundancy branch, can advantageously be controlled in order to actuate the lock. Because not only redundant control channels, but also redundant actuating devices for actuating the lock are provided, a correspondingly higher degree of security is achieved when the lock is actuated.
- the various redundancy branches are each assigned their own energy source to supply them with electrical energy in particular, with at least one further redundancy branch with energy preferably also being assigned to the energy source assigned to a respective redundancy branch is supplyable.
- Both the energy source assigned to the relevant redundancy branch and the a respective further redundancy branch associated energy source can be monitored.
- this redundancy branch can also be supplied with energy via the energy source of at least one further redundancy branch.
- the various energy sources can be monitored continuously or at predetermined time intervals via the control channel of a respective redundancy branch.
- the actuating unit assigned to it can be controlled by the control channel of the control device of the locking device assigned to the redundancy branch and can be determined by this control channel on the basis of feedback whether the lock has been activated or not.
- a respective control channel can thus test whether it can activate the lock via the associated actuating unit. He can use the feedback to monitor whether the lock can be activated.
- the actuating unit assigned to this can be controlled by the control channel of the control device of the blocking device assigned to the redundant branch and the current flowing through the actuating device can be monitored through this control channel.
- an incomplete test of a respective redundancy branch is possible, for example, by the assigned actuating unit being supplied with only enough energy that the lock does not move or rotate further or against a stop is pressed. The current flowing through the actuating device is then monitored.
- the control device of the blocking device is expediently designed in such a way that the various redundancy branches are mutually monitored via its control channels.
- control device of the locking device can also be designed so that when a fault is detected in a respective redundancy branch, the lock can be activated via at least one further redundancy branch after the wing has been locked.
- a bistable lock that can be actuated by an electric motor is provided as the lock, with an actuating unit for actuating the lock preferably comprising an electric motor.
- an electromagnetically actuable lock can also be provided as the lock.
- the lock advantageously comprises a bistable, electromagnetically actuable lock.
- an actuating unit for actuating the lock preferably comprises two bistable electromagnets or one bistable electromagnet with two coil units.
- the armature of a respective bistable electromagnet can be coupled or is coupled to the lock, preferably via a mechanical transmission. In this way, in particular, an erroneous resetting of the lock when the sash strikes can be prevented.
- a lock that can be actuated electromagnetically according to the quiescent current principle can also be provided as the lock.
- an actuation unit for actuating the lock preferably comprises a permanent magnet and at least one electric coil assigned to it, the lock being held in its deactivated state by the magnetic field of the permanent magnet when the electric coil is not energized, and when the electric coil is energized and a deactivation effected thereby Compensation of the magnetic field of the permanent magnet can be activated in particular by gravity, a spring force and/or the like. In this case, only incomplete testing of the lock activation is possible, since the activated lock can only be deactivated manually.
- the system according to the invention for determining a wing of a door, a window or the like comprises a drive with at least one mechanical energy store, which is charged by an opening movement of the wing and discharged with a closing movement of the wing.
- the drive can in particular be a door closer.
- the hold-open system according to the invention comprises a hold-open device working according to the closed-circuit principle with a permanent magnet unit for holding the wing in place and at least one electrical coil which can be controlled via a control device in such a way that the magnetic field is compensated and the hold-open device is thus triggered and the wing released.
- the locking device is preferred, in particular with regard to the energy supply, the electrical actuation of the at least one coil and/or the coil itself is carried out with one or more redundancies by a corresponding number of redundancy branches.
- the lock can also be controlled in one or more redundant ways via a corresponding number of redundancy branches and the operability of the various redundancy branches assigned to the lock can be monitored via the assigned control device, a closed-circuit current protection is also possible in the event of a complete failure or a failure of the last redundancy branch.
- Locking device ruled out that the leaf is held open in the event of fire, since the lock can still be safely activated before the last redundancy branch of the locking device fails.
- the redundancy branches for activating the lock and the redundancy branches for activating the locking device are preferably at least partially separate from one another, the redundant branches which are separate from one another being advantageously connectable or connected to one another via a communication link.
- the redundancy branches for activating the lock and the redundancy branches for activating the locking device at least partially include common components such as in particular common energy sources, a common control device or common microcontroller and/or the like and/or for activating the lock and common redundancy branches are provided for controlling the locking device.
- the blocking device and the locking device can preferably be controlled via the redundancy branches in such a way that when the locking device of the wing is activated when a fault is detected in a respective redundancy branch of the locking device First, the locking device can be triggered and, after the wing has been locked, the lock can be activated via at least one further redundancy branch of the locking device.

Description
Die Erfindung betrifft eine Anlage zur Feststellung eines Flügels einer Tür, eines Fensters oder dergleichen mit einer Sperrvorrichtung zum Sperren, das heißt Verhindern der Feststellung eines über eine Feststellvorrichtung feststellbaren Flügels einer Tür, eines Fensters oder dergleichen, mit einer insbesondere elektromotorisch und/oder elektromagnetisch betätigbaren, über eine Steuerungseinrichtung ansteuerbaren Sperre.The invention relates to a system for securing a wing of a door, a window or the like with a blocking device for locking, i.e. preventing the fixing of a wing of a door, a window or the like that can be locked via a locking device, with a device that can be actuated in particular by an electric motor and/or electromagnetically , Controllable via a control device lock.
Eine Feststellanlage ist eine Einrichtung zum Offenhalten von Brandabschlüssen wie insbesondere Brandschutztüren, Rauchschutztüren und/oder dergleichen. Sie sorgt dafür, dass Feuerschutzabschlüsse bzw. Rauchabschlüsse offengehalten werden, bei einem Brand bzw. im Fall von Rauchentwicklung jedoch sicher schließen.A hold-open system is a device for keeping fire closures open, in particular fire protection doors, smoke protection doors and/or the like. It ensures that fire protection closures or smoke closures are kept open, but close securely in the event of a fire or if smoke develops.
Es sind unter anderem Feststellanlagen bekannt, die eine geöffnete Brandschutztür entgegen der Federkraft eines mechanischen Speichers eines Antriebs ständig offenhalten. Im Brandfall löst die Feststellanlage aus, wodurch die Tür durch die Federkraft des mechanischen Speichers schließt. Dabei umfasst die Feststellanlage in der Regel eine elektrische Energieversorgung, eine Feststellvorrichtung, eine Auslösevorrichtung und eine Branddetektion.Among other things, hold-open systems are known which constantly keep an open fire protection door open against the spring force of a mechanical memory of a drive. In the event of a fire, the hold-open system is triggered, causing the door to close using the spring force of the mechanical memory. The hold-open system generally includes an electrical power supply, a hold-open device, a triggering device and a fire detection system.
Auch Antriebe wie insbesondere Türschließer oder bewegliche Türflügel mit einem mechanischen Energiespeicher sind allgemein bekannt. Beim manuellen Öffnen des Türflügels wird der mechanische Energiespeicher mit potentieller Energie aufgeladen, welche den losgelassenen Flügel wieder schließt. Der mechanische Energiespeicher kann beispielsweise eine Federeinheit umfassen, die durch das manuelle Öffnen des Türflügels gespannt wird und sich mit dem Schließen des Türflügels wieder entspannt.Drives such as in particular door closers or movable door leaves with a mechanical energy store are also generally known. When the door leaf is opened manually, the mechanical energy store is charged with potential energy, which closes the released leaf again. The mechanical energy store can, for example, include a spring unit that is manual opening of the door leaf is tensioned and released again when the door leaf is closed.
Zur Feststellung eines Flügels einer Tür, eines Fensters oder dergleichen wurde auch bereits eine Ruhestrom-Feststellvorrichtung vorgeschlagen, die auf einer einen Permanentmagneten und eine oder mehrere Spulen umfassenden Anordnung basiert. Dabei ist der Flügel bei nicht bestromter Spule durch den Permanentmagneten feststellbar, während die Feststellung mit einer zur Kompensation des Magnetfeldes des Permanentmagneten erfolgenden Bestromung der Spule auslösbar ist. Es kann beispielsweise ein an der Wand oder dem Türflügel vorgesehener Türhaftmagnet mit integrierten Spulen mit einer auf dem Türflügel angebrachten Ankerplatte zusammenwirken. Denkbar ist beispielsweise auch eine in einer Gleitschiene integrierte elektromechanische Feststellvorrichtung, bei der mittels eines Permanentmagneten ein in der Gleitschiene geführter Gleitstein direkt oder über eine mechanische Übersetzung feststellbar ist. Dabei muss die betreffende Anordnung nicht fest mit dem Türflügel verbunden sein (Freeswing).A quiescent current locking device based on an arrangement comprising a permanent magnet and one or more coils has already been proposed for locking a leaf of a door, a window or the like. The vane can be locked by the permanent magnet when the coil is not energized, while the locking can be triggered by energizing the coil to compensate for the magnetic field of the permanent magnet. For example, a door holding magnet provided on the wall or on the door leaf with integrated coils can interact with an anchor plate mounted on the door leaf. It is also conceivable, for example, to have an electromechanical locking device integrated in a slide rail, in which a sliding block guided in the slide rail can be fixed directly or via a mechanical transmission by means of a permanent magnet. The arrangement in question does not have to be firmly connected to the door leaf (free swing).
Wird bei einer Tür mit zugeordnetem Antrieb bzw. Türschließer der Türflügel geöffnet, so wird potentielle Energie in die Federeinheit des Antriebs bzw. Türschließers geladen. Erreicht beispielsweise bei einer Feststellvorrichtung mit Ankerplatte die Ankerplatte den Permanentmagneten, so hält dieser die Ankerplatte gegen die Schließkraft des Antriebs bzw. Türschließers fest. Zum Auslösen dieser Feststellung können eine oder mehrere Spulen bestromt werden, um das Magnetfeld des Permanentmagneten zu kompensieren. Durch die im Türschließer gespeicherte potentielle Energie entfernt sich mit dem Türflügel auch die Ankerplatte wieder vom Permanentmagneten, woraufhin der Türschließer den Türflügel schließt. Sobald die Ankerplatte hinreichend weit vom Permanentmagneten entfernt ist, wird der Strom durch die wenigstens eine Spule wieder abgeschaltet.If the door leaf is opened on a door with an associated drive or door closer, potential energy is loaded into the spring unit of the drive or door closer. For example, if the anchor plate of a locking device with an anchor plate reaches the permanent magnet, this holds the anchor plate against the closing force of the drive or door closer. To trigger this determination, one or more coils can be energized to compensate for the magnetic field of the permanent magnet. Due to the potential energy stored in the door closer, the anchor plate moves away from the permanent magnet with the door leaf, whereupon the door closer closes the door leaf. As soon as the armature plate is sufficiently far away from the permanent magnet, the current through the at least one coil is switched off again.
Eine solche Ruhestrom-Feststellvorrichtung besitzt gegenüber nach dem Arbeitsstromprinzip arbeitenden herkömmlichen Feststellvorrichtungen den wesentlichen Vorteil, dass nur für die relativ kurze Zeit des Auslösens der Feststellvorrichtung elektrische Energie benötigt wird.Such a quiescent current locking device has the significant advantage over conventional locking devices working according to the working current principle that electrical energy is only required for the relatively short time of triggering the locking device.
Damit eine nach dem Ruhestromprinzip arbeitende Feststellvorrichtung sicher auslöst, wurde auch bereits vorgeschlagen, solche Feststellvorrichtungen bezüglich der Energieversorgung, der elektrischen Ansteuerung der Spulen und der Spulen selbst ein- oder mehrfach redundant auszulegen.So that a locking device working according to the quiescent current principle triggers reliably, it has already been proposed to design such locking devices with single or multiple redundancies with regard to the energy supply, the electrical control of the coils and the coils themselves.
Bei einer solchen redundant ausgelegten Feststellvorrichtung kann die Redundanz überwacht werden. Bei Ausfall eines Redundanzzweiges ist die Feststellvorrichtung über einen anderen Redundanzzweig auslösbar, woraufhin der Türflügel schließen kann.With such a redundantly designed locking device, the redundancy can be monitored. If one redundancy branch fails, the locking device can be triggered via another redundancy branch, after which the door leaf can close.
Gegenüber den herkömmlichen Feststellvorrichtungen nach dem Arbeitsstromprinzip sowie gegenüber auf einem bistabilen Prinzip basierenden Feststellvorrichtungen weist eine Ruhestrom-Feststellvorrichtung nun aber insbesondere den Nachteil auf, dass sie im Alarmfall nicht mehr auslösen kann, wenn der Türflügel nach einem Ausfall des letzten Redundanzzweiges geöffnet wird und die Ankerplatte den Permanentmagneten erreicht. So besteht dann auch keine Möglichkeit mehr, die Auslösung der Feststellung über einen Redundanzzweig auszulösen.Compared to conventional locking devices based on the working current principle and locking devices based on a bistable principle, a locked current locking device has the particular disadvantage that it can no longer be triggered in the event of an alarm if the door leaf is opened after a failure of the last redundancy branch and the anchor plate reaches the permanent magnet. There is then also no longer any possibility of triggering the determination via a redundancy branch.
Es sind auch bereits mechanische Sperren bekannt, durch die das Annähern der Ankerplatte an den Permanentmagneten verhindert werden kann, um eine Feststellung des Flügels zu verhindern. Solche Sperren sind üblicherweise elektromotorisch oder elektromagnetisch betätigbar. Um Energie zu sparen, kann auch die Ansteuerung einer solchen Sperre nach dem Ruhestromprinzip oder nach einem bistabilen Prinzip ausgeführt sein.Mechanical locks are also already known, by means of which the approach of the armature plate to the permanent magnet can be prevented in order to prevent the wing from being locked. Such locks can usually be actuated by an electric motor or electromagnetically. In order to save energy, such a lock can also be controlled according to the quiescent current principle or according to a bistable principle.
Tritt nun aber ein Fehler in der Ansteuerung einer solchen Sperre auf, so kann die Sperre nicht mehr aktiviert werden. Wird jetzt der Türflügel nach einem Ausfall des letzten Redundanzzweiges der Auslösevorrichtung geöffnet, wird sich die Ankerplatte dem Permanentmagneten nähern, wodurch der Türflügel offengehalten wird. Die Tür bleibt demzufolge in einem Brandfall offen.
Der Erfindung liegt die Aufgabe zugrunde, eine Feststellanlage der eingangs genannten Art anzugeben, bei der die zuvor erwähnten Probleme beseitigt sind. Dabei soll insbesondere gewährleistet sein, dass die Sperre auch bei möglicherweise auftretenden Fehlern in deren Ansteuerung und insbesondere bei einer einfach- oder mehrfach redundant ausgeführten Ruhestrom-Feststellvorrichtung auch noch vor einem Ausfall des letzten Redundanzzweiges der Feststellvorrichtung noch sicher aktivierbar ist.The invention is based on the object of specifying a hold-open system of the type mentioned at the outset, in which the aforementioned problems are eliminated. In particular, it should be ensured that the lock can still be safely activated even if errors occur in its control and in particular in the case of a single or multiple redundant closed-circuit current locking device even before the last redundancy branch of the locking device fails.
Erfindungsgemäß wird diese Aufgabe durch eine Feststellanlage mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen der erfindungsgemäßen Feststellanlage ergeben sich aus den Unteransprüchen, der vorliegenden Beschreibung sowie der Zeichnung.According to the invention, this object is achieved by a hold-open system with the features of claim 1. Preferred embodiments of the hold-open system according to the invention result from the dependent claims, the present description and the drawing.
Die erfindungsgemäße Anlage mit Vorrichtung zum Sperren der Feststellung eines über eine Feststellvorrichtung feststellbaren Flügels einer Tür, eines Fensters oder dergleichen umfasst eine insbesondere elektromotorisch und/oder elektromagnetisch betätigbare, über eine Steuerungseinrichtung ansteuerbare Sperre. Dabei ist die Steuerungseinrichtung ein- oder mehrfach redundant ausgeführt, wobei die Sperre über eine entsprechende Anzahl von Redundanzzweigen ansteuerbar und die Funktionsfähigkeit der verschiedenen Redundanzzweige über die Steuerungseinrichtung jeweils überwachbar ist.The system according to the invention with a device for blocking the locking of a leaf of a door, a window or the like that can be locked via a locking device comprises a lock that can be actuated in particular by an electric motor and/or electromagnetically and can be controlled via a control device. In this case, the control device is designed with one or more redundancies, the lock being able to be controlled via a corresponding number of redundancy branches and the operability of the various redundancy branches being able to be monitored via the control device in each case.
Es ist somit auch bei einem vollständigen Ausfall bzw. einem Ausfall auch des letzten Redundanzzweiges der Ansteuerung der Feststellvorrichtung ausgeschlossen, dass der Flügel im Brandfall offengehalten wird, da die Sperre auch vor dem Ausfall des letzten Redundanzzweiges der Feststellvorrichtung noch sicher aktivierbar ist.It is thus excluded even in the case of a complete failure or a failure of the last redundancy branch of the activation of the locking device, that the sash is kept open in the event of a fire, since the lock can still be safely activated before the failure of the last redundancy branch of the hold-open device.
Bevorzugt ist die Funktionsfähigkeit eines jeweiligen Redundanzzweiges durch die Steuerungseinrichtung kontinuierlich oder in vorgebbaren zeitlichen Abständen überwachbar.The functionality of a respective redundancy branch can preferably be monitored by the control device continuously or at definable time intervals.
Gemäß einer zweckmäßigen praktischen Ausführungsform der erfindungsgemäßen Anlage umfasst die Steuerungseinrichtung der Sperrvorrichtung zumindest zwei redundant ausgeführte, jeweils einem Redundanzzweig zugeordnete Steuerkanäle.According to an expedient practical embodiment of the system according to the invention, the control device of the blocking device comprises at least two redundant control channels each assigned to a redundancy branch.
Dabei ist über die verschiedenen Steuerkanäle der Steuerungseinrichtung vorteilhafterweise jeweils eine dem betreffenden Redundanzzweig zugeordnete eigene insbesondere elektromotorische und/oder elektromagnetische Betätigungseinrichtung zur Betätigung der Sperre ansteuerbar. Indem nicht nur redundante Steuerkanäle, sondern auch redundante Betätigungseinrichtungen zur Betätigung der Sperre vorgesehen sind, wird eine entsprechend höhere Sicherheit bei der Ansteuerung der Sperre erreicht.In this case, via the various control channels of the control device, one of its own, in particular electromotive and/or electromagnetic, actuating devices, assigned to the relevant redundancy branch, can advantageously be controlled in order to actuate the lock. Because not only redundant control channels, but also redundant actuating devices for actuating the lock are provided, a correspondingly higher degree of security is achieved when the lock is actuated.
Zur weiteren Erhöhung der Sicherheit der Ansteuerung der Sperre ist insbesondere auch von Vorteil, wenn den verschiedenen Redundanzzweigen zu deren Versorgung mit insbesondere elektrischer Energie jeweils eine eigene Energiequelle zugeordnet ist, wobei über die einem jeweiligen Redundanzzweig zugeordnete Energiequelle bevorzugt jeweils auch zumindest ein weiterer Redundanzzweig mit Energie versorgbar ist.To further increase the safety of the control of the lock, it is also particularly advantageous if the various redundancy branches are each assigned their own energy source to supply them with electrical energy in particular, with at least one further redundancy branch with energy preferably also being assigned to the energy source assigned to a respective redundancy branch is supplyable.
Bevorzugt ist über den Steuerkanal eines jeweiligen Redundanzzweiges sowohl die dem betreffenden Redundanzzweig zugeordnete Energiequelle als auch die einem jeweiligen weiteren Redundanzzweig zugeordnete Energiequelle überwachbar.Both the energy source assigned to the relevant redundancy branch and the a respective further redundancy branch associated energy source can be monitored.
Fällt beispielsweise eine einem Redundanzzweig zugeordnete Energiequelle aus, so kann dieser Redundanzzweig auch über die Energiequelle wenigstens eines weiteren Redundanzzweiges mit Energie versorgt werden.If, for example, an energy source assigned to a redundancy branch fails, then this redundancy branch can also be supplied with energy via the energy source of at least one further redundancy branch.
Vorteilhafterweise sind die verschiedenen Energiequellen über den Steuerkanal eines jeweiligen Redundanzzweiges kontinuierlich oder in vorgebbaren zeitlichen Abständen überwachbar.Advantageously, the various energy sources can be monitored continuously or at predetermined time intervals via the control channel of a respective redundancy branch.
Gemäß einer weiteren bevorzugten praktischen Ausführungsform der erfindungsgemäßen Anlage ist, insbesondere bei ausgelöster Feststellung des Flügels, zur Überwachung der Funktionsfähigkeit eines jeweiligen Redundanzzweiges die diesem zugeordnete Betätigungseinheit durch den dem Redundanzzweig zugeordneten Steuerkanal der Steuerungseinrichtung der Sperrvorrichtung ansteuerbar und durch diesen Steuerkanal anhand einer Rückmeldung feststellbar, ob die Sperre aktiviert wurde oder nicht.According to a further preferred practical embodiment of the system according to the invention, in particular when the locking of the wing has been triggered, to monitor the functionality of a respective redundancy branch, the actuating unit assigned to it can be controlled by the control channel of the control device of the locking device assigned to the redundancy branch and can be determined by this control channel on the basis of feedback whether the lock has been activated or not.
Ein jeweiliger Steuerkanal kann somit bei ausgelöster Feststellung testen, ob er über die zugeordnete Betätigungseinheit die Sperre aktivieren kann. Über die Rückmeldung kann er die Aktivierbarkeit der Sperre überwachen.When a determination is triggered, a respective control channel can thus test whether it can activate the lock via the associated actuating unit. He can use the feedback to monitor whether the lock can be activated.
Von Vorteil ist insbesondere auch, wenn, insbesondere bei aktivierter Feststellung des Flügels, zur Überwachung der Funktionsfähigkeit eines jeweiligen Redundanzzweiges die diesem zugeordnete Betätigungseinheit durch den dem Redundanzzweig zugeordneten Steuerkanal der Steuerungseinrichtung der Sperrvorrichtung ansteuerbar und durch diesen Steuerkanal der durch die Betätigungseinrichtung fließende Strom überwachbar ist.It is also particularly advantageous if, in particular when the locking of the wing is activated, in order to monitor the functionality of a respective redundant branch, the actuating unit assigned to this can be controlled by the control channel of the control device of the blocking device assigned to the redundant branch and the current flowing through the actuating device can be monitored through this control channel.
Bei aktivierter Feststellung, bei der beispielsweise eine Ankerplatte an einem Permanentmagneten anliegt, ist somit eine unvollständige Testung eines jeweiligen Redundanzzweiges möglich, indem die zugeordnete Betätigungseinheit beispielsweise nur mit so viel Energie versorgt wird, dass die Sperre nicht weiter bewegt oder gedreht bzw. gegen einen Anschlag gedrückt wird. Der dabei durch die Betätigungseinrichtung fließende Strom wird dann überwacht.When the detection is activated, for example, in which an anchor plate is in contact with a permanent magnet, an incomplete test of a respective redundancy branch is possible, for example, by the assigned actuating unit being supplied with only enough energy that the lock does not move or rotate further or against a stop is pressed. The current flowing through the actuating device is then monitored.
Zweckmäßigerweise ist die Steuerungseinrichtung der Sperrvorrichtung so ausgeführt, dass über deren Steuerkanäle eine gegenseitige Überwachung der verschiedenen Redundanzzweige erfolgt.The control device of the blocking device is expediently designed in such a way that the various redundancy branches are mutually monitored via its control channels.
Vorteilhafterweise kann die Steuerungseinrichtung der Sperrvorrichtung zudem so ausgeführt sein, dass bei einem erkannten Fehler eines jeweiligen Redundanzzweiges die Sperre nach gelöster Feststellung des Flügels über wenigstens einen weiteren Redundanzzweig aktivierbar ist.Advantageously, the control device of the locking device can also be designed so that when a fault is detected in a respective redundancy branch, the lock can be activated via at least one further redundancy branch after the wing has been locked.
Gemäß einer vorteilhaften praktischen Ausführungsform der erfindungsgemäßen Anlage ist als Sperre eine elektromotorisch betätigbare bistabile Sperre vorgesehen, wobei eine Betätigungseinheit zur Betätigung der Sperre bevorzugt einen Elektromotor umfasst.According to an advantageous practical embodiment of the system according to the invention, a bistable lock that can be actuated by an electric motor is provided as the lock, with an actuating unit for actuating the lock preferably comprising an electric motor.
Gemäß einer vorteilhaften alternativen Ausführungsform der erfindungsgemäßen Anlage kann als Sperre auch eine elektromagnetisch betätigbare Sperre vorgesehen sein.According to an advantageous alternative embodiment of the system according to the invention, an electromagnetically actuable lock can also be provided as the lock.
Dabei umfasst die Sperre vorteilhafter Weise eine bistabile elektromagnetisch betätigbare Sperre. In diesem Fall umfasst eine Betätigungseinheit zur Betätigung der Sperre bevorzugt zwei bistabile Elektromagnete oder einen bistabilen Elektromagneten mit zwei Spuleneinheiten.In this case, the lock advantageously comprises a bistable, electromagnetically actuable lock. In this case, an actuating unit for actuating the lock preferably comprises two bistable electromagnets or one bistable electromagnet with two coil units.
Der Anker eines jeweiligen bistabilen Elektromagneten ist zur Betätigung der Sperre bevorzugt über eine mechanische Übersetzung mit der Sperre koppelbar oder gekoppelt. Dadurch kann insbesondere ein fehlerhaftes Zurücksetzen der Sperre bei anschlagendem Flügel verhindert werden.To actuate the lock, the armature of a respective bistable electromagnet can be coupled or is coupled to the lock, preferably via a mechanical transmission. In this way, in particular, an erroneous resetting of the lock when the sash strikes can be prevented.
Gemäß einer vorteilhaften alternativen Ausführungsform der erfindungsgemäßen Anlage kann als Sperre auch eine nach dem Ruhestromprinzip elektromagnetisch betätigbare Sperre vorgesehen sein.According to an advantageous alternative embodiment of the system according to the invention, a lock that can be actuated electromagnetically according to the quiescent current principle can also be provided as the lock.
In diesem Fall umfasst eine Betätigungseinheit zur Betätigung der Sperre bevorzugt einen Permanentmagneten und wenigstens eine diesem zugeordnete elektrische Spule, wobei die Sperre bei nicht bestromter elektrischer Spule durch das Magnetfeld des Permanentmagneten in ihrem deaktivierten Zustand gehalten und bei einer Bestromung der elektrischen Spule und einer dadurch bewirkten Kompensation des Magnetfeldes des Permanentmagneten insbesondere durch die Schwerkraft, eine Federkraft und/oder dergleichen aktivierbar ist. In diesem Fall ist lediglich eine unvollständige Testung der Ansteuerung der Sperre möglich, da die aktivierte Sperre nur manuell deaktiviert werden kann.In this case, an actuation unit for actuating the lock preferably comprises a permanent magnet and at least one electric coil assigned to it, the lock being held in its deactivated state by the magnetic field of the permanent magnet when the electric coil is not energized, and when the electric coil is energized and a deactivation effected thereby Compensation of the magnetic field of the permanent magnet can be activated in particular by gravity, a spring force and/or the like. In this case, only incomplete testing of the lock activation is possible, since the activated lock can only be deactivated manually.
Die erfindungsgemäße Anlage zur Feststellung eines Flügels einer Tür, eines Fensters oder dergleichen umfasst einen Antrieb mit wenigstens einem mechanischen Energiespeicher, der durch eine Öffnungsbewegung des Flügels aufgeladen und mit einer Schließbewegung des Flügels entladen wird. Dabei kann es sich bei dem Antrieb insbesondere um einen Türschließer handeln. Zudem umfasst die erfindungsgemäße Feststellanlage eine nach dem Ruhestromprinzip arbeitende Feststellvorrichtung mit einer Permanentmagneteinheit zur Feststellung des Flügels und wenigstens einer elektrischen Spule, die über eine Steuerungseinrichtung so ansteuerbar ist, dass eine Kompensation des Magnetfeldes und damit eine Auslösung der Feststellvorrichtung und Freigabe des Flügels erfolgt. Bevorzugt ist dabei die Feststellvorrichtung insbesondere bezüglich der Energieversorgung, der elektrischen Ansteuerung der wenigstens einen Spule und/oder der Spule selbst durch eine entsprechende Anzahl von Redundanzzweigen ein- oder mehrfach redundant ausgeführt.The system according to the invention for determining a wing of a door, a window or the like comprises a drive with at least one mechanical energy store, which is charged by an opening movement of the wing and discharged with a closing movement of the wing. The drive can in particular be a door closer. In addition, the hold-open system according to the invention comprises a hold-open device working according to the closed-circuit principle with a permanent magnet unit for holding the wing in place and at least one electrical coil which can be controlled via a control device in such a way that the magnetic field is compensated and the hold-open device is thus triggered and the wing released. The locking device is preferred, in particular with regard to the energy supply, the electrical actuation of the at least one coil and/or the coil itself is carried out with one or more redundancies by a corresponding number of redundancy branches.
Indem erfindungsgemäß auch die Sperre über eine entsprechende Anzahl von Redundanzzweigen ein- oder mehrfach redundant ansteuerbar und die Funktionsfähigkeit der verschiedenen der Sperre zugeordneten Redundanzzweige über die zugeordnete Steuerungseinrichtung überwachbar ist, ist auch bei einem vollständigen Ausfall bzw. einem Ausfall auch des letzten Redundanzzweiges einer Ruhestrom-Feststellvorrichtung ausgeschlossen, dass der Flügel im Brandfall offengehalten wird, da die Sperre auch vor dem Ausfall des letzten Redundanzzweiges der Feststellvorrichtung noch sicher aktivierbar ist.Since, according to the invention, the lock can also be controlled in one or more redundant ways via a corresponding number of redundancy branches and the operability of the various redundancy branches assigned to the lock can be monitored via the assigned control device, a closed-circuit current protection is also possible in the event of a complete failure or a failure of the last redundancy branch. Locking device ruled out that the leaf is held open in the event of fire, since the lock can still be safely activated before the last redundancy branch of the locking device fails.
Bevorzugt sind die Redundanzzweige zur Ansteuerung der Sperre und die Redundanzzweige zur Ansteuerung der Feststellvorrichtung zumindest teilweise getrennt voneinander ausgeführt sind, wobei die getrennt voneinander ausgeführten Redundanzzweige vorteilhafterweise über eine Kommunikationsverbindung miteinander verbindbar oder verbunden sind.The redundancy branches for activating the lock and the redundancy branches for activating the locking device are preferably at least partially separate from one another, the redundant branches which are separate from one another being advantageously connectable or connected to one another via a communication link.
In bestimmten Fällen ist auch von Vorteil, wenn die Redundanzzweige zur Ansteuerung der Sperre und die Redundanzzweige zur Ansteuerung der Feststellvorrichtung zumindest teilweise gemeinsame Bauelemente wie insbesondere gemeinsame Energiequellen, eine gemeinsame Steuerungseinrichtung bzw. gemeinsame Mikrocontroller und/oder dergleichen umfassen und/oder zur Ansteuerung der Sperre und zur Ansteuerung der Feststellvorrichtung gemeinsame Redundanzzweige vorgesehen sind.In certain cases, it is also advantageous if the redundancy branches for activating the lock and the redundancy branches for activating the locking device at least partially include common components such as in particular common energy sources, a common control device or common microcontroller and/or the like and/or for activating the lock and common redundancy branches are provided for controlling the locking device.
Bevorzugt sind die Sperrvorrichtung und die Feststellvorrichtung über die Redundanzzweige so ansteuerbar, dass bei aktivierter Feststellung des Flügels bei einem erkannten Fehler eines jeweiligen Redundanzzweiges der Sperrvorrichtung zunächst die Feststellvorrichtung auslösbar und nach gelöster Feststellung des Flügels über wenigstens einen weiteren Redundanzzweig der Sperrvorrichtung die Sperre aktivierbar ist.The blocking device and the locking device can preferably be controlled via the redundancy branches in such a way that when the locking device of the wing is activated when a fault is detected in a respective redundancy branch of the locking device First, the locking device can be triggered and, after the wing has been locked, the lock can be activated via at least one further redundancy branch of the locking device.

Eine weitere Feststellung des Türflügels ist jetzt nicht mehr möglich.If an error is detected in a
Als Sperre 14 kann beispielsweise auch eine elektromagnetisch betätigbare Sperre vorgesehen sein. Dabei kann die Sperre 14 beispielsweise als eine bistabile elektromagnetisch betätigbare Sperre oder als eine nach dem Ruhestromprinzip elektromagnetisch betätigbare Sperre ausgeführt sein.
