Die
In der
Der Erfindung liegt die Aufgabe zugrunde, eine kompakte Verriegelung für einen Flügel einer Tür oder eines Fensters auszubilden, welche auch unter Vorlast zuverlässig auslöst.The invention has for its object to form a compact lock for a wing of a door or a window, which reliably triggers even under preload.
Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The object is solved by the features of
Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung. Bekannte elektrisch betätigbare Verriegelungen an Türen oder Fenstern weisen ein schwenkbar gelagertes Fallenelement auf, in welches eine Falle eines üblicherweise im Flügel der Türe oder des Fensters angeordneten Schlosses eingreift. Derartige Verriegelungen sind auch als sogenannte Türöffner bekannt. Weiterhin kann in anderer Ausgestaltung unabhängig von Schloss eine Verriegelung vorgesehen sein, wobei ein Fallenelement in eine mit einem Schließblech versehene Aussparung eingreift. In besonderer Ausführungsform kann die Verriegelung mit Kreuzfallenelementen versehen sein, welche vorteilhaft in das Gehäuse der Verriegelung einschwenken können.The subclaims form advantageous embodiments of the invention. Known electrically actuated locks on doors or windows have a pivotally mounted latch element, in which engages a case of a usually arranged in the wing of the door or the window lock. Such locks are also known as so-called door opener. Furthermore, in another embodiment, a lock may be provided independently of the lock, with a latch element engaging in a recess provided with a strike plate. In a particular embodiment, the lock can be provided with cross latch elements, which can advantageously pivot into the housing of the lock.
Je nach Ausführung der Verriegelung kann damit ein Flügel, wie im Falle des Türöffners, von außen verriegelt sein, wobei von innen her der Flügel durch einen am Schloss angeordneten Drücker geöffnet werden kann, wie es beispielsweise an Hauseingangstüren gebräuchlich ist. Weiterhin kann es in Fluchtwegen vorteilhaft sein, dass eine zusätzlich angeordnete, elektrisch betätigbare Verriegelung vorhanden ist, wenn es sich beispielsweise um Türen in Kaufhäusern, in forensischen Kliniken oder dergleichen handelt, die im Normalfall gesichert sein sollen. Diese Verriegelungen müssen im Notfall, beispielsweise bei Feuer, durch eine Rauch- und Brandmeldeanlage fernbetätigt entriegelt werden können. Auch bei einem Stromausfall muss sicherheitshalber eine Entriegelung erfolgen. Daher sind diese Verriegelungen so beschaffen, dass die Verriegelung durch Bestromung eines Aktors, etwa eines Elektromagneten, aufrecht erhalten wird, sodass prinzipbedingt eine Entriegelung bei Stromausfall erfolgt.Depending on the design of the lock so that a wing, as in the case of the door opener, be locked from the outside, from the inside the wing can be opened by a press arranged on the lock, as is common, for example, at the front doors. Furthermore, it may be advantageous in escape routes that an additionally arranged, electrically actuated lock is present, if it is, for example, doors in department stores, in forensic clinics or the like, which should be secured under normal circumstances. These locks must be able to be unlocked in case of emergency, such as fire, remote controlled by a smoke and fire alarm system. Even in the event of a power failure, a safety release must be carried out. Therefore, these locks are such that the lock is maintained by energizing an actuator, such as an electromagnet, so that in principle takes place unlocking in case of power failure.
Weiterhin ist es besonders wichtig, dass auch bei einer auf die Verriegelung einwirkenden Vorlast, wie diese etwa durch flüchtende Personen auf eine noch verriegelte Türe entsteht, nicht zum Klemmen der Verriegelung führt, sondern diese noch sicher auslöst.Furthermore, it is particularly important that even with a preload acting on the latch, as it arises for example by escaping persons on a still locked door, does not lead to the terminals of the lock, but still triggers them safely.
Dies wird erreicht, indem die auf das bzw. die Fallenelemente der Verriegelung einwirkende Kraft in mehreren Stufen mittels Hebeln so umgesetzt wird, dass die Krafteinleitung jeweils nahe an einer Drehachse des Hebels erfolgt und die Kraftweiterleitung in die nächste Stufe endseitig an dem von der Drehachse entfernten Ende des Hebels erfolgt, wodurch die Kraft jeweils erheblich reduziert wird. Weiterhin erfolgt die Kraftweiterleitung über Schrägflächen, wodurch ebenfalls eine Übersetzung der Kräfte bewirkt ist. In der Gesamtheit kann somit eine Reduzierung der Vorlast auf eine Kraft von weniger als 1% erfolgen, welche noch an dem vom dem Elektromagneten betätigten Sperrelement, beispielsweise einem Sperrhebel, ansteht.This is accomplished by translating the force applied to the latch element (s) by means of levers in a plurality of stages such that the application of force occurs close to an axis of rotation of the lever and the forwarding of force to the next step is remote from the axis of rotation End of the lever takes place, whereby the force is significantly reduced in each case. Furthermore, the force is transmitted via inclined surfaces, which also causes a translation of the forces. As a whole, it is thus possible to reduce the preload to a force of less than 1%, which is still present at the blocking element actuated by the electromagnet, for example a blocking lever.
Im Nachfolgenden wird ein Ausführungsbeispiel in der Zeichnung anhand der Figuren näher erläutert.In the following an embodiment in the drawing with reference to the figures will be explained in more detail.

Häufig ist es, wie im vorliegenden Ausführungsbeispiel, vorgesehen, dass die Verriegelung 1 bei aktivem, d.h. bestromtem Elektromagneten 6 gesperrt ist und die Fallenelemente 4 verriegelt sind. Das ist insbesondere bei einer Anwendung in Fluchtwegen erwünscht, da der Fluchtweg bei Stromausfall freigegeben und der Flügel entriegelt sein muss. Zum Anschluss der Verriegelung 1 ist weiterhin eine Platine 13 mit Klemmen 14 im Gehäuse 3 angeordnet. Die Elektronik auf der Platine ist ausgebildet, Meldesignale über den Zustand der Verriegelung 1, wie verriegelt oder entriegelt, und über den Zustand des Flügels, offen oder geschlossen, bereitzustellen. Auf der Platine 13 kann auch die Anordnung einer Stromregelung für den Elektromagneten 6 vorgesehen sein, welche nach einem anfänglich hohen erforderlichen Strom beim Anzug des Elektromagneten 6 auf einen niedrigen Haltestrom zurück regelt, um eine thermische Überlastung des im verriegelten Zustand der Verrieglung 1 dauerhaft bestromten Elektromagneten 6 zu verhindern. Kostengünstig und energieschonend wird so der Stromverbrauch reduziert. Weiterhin können auch weitere Signale, wie der Zustand des Verriegelungshebels 11, intern verarbeitet werden, wobei diese Signale nicht extern an den Klemmen 14 bereit gestellt werden.The
Im Folgenden zunächst zum allgemeinen Verständnis die Erläuterung der Anordnung der Elemente der Sperranordnung der Verriegelung 1. Der in der
Wesentlich ist, dass durch die mehrstufige Sperranordnung Kräfte, welche durch eine Vorlast auf die Fallenelemente 4 einwirkt, wesentlich reduziert werden können, um ein sicheres Auslösen der Verrieglung 1 selbst bei hoher Vorlast sicherzustellen. Eine Vorlast auf die gesperrten Fallenelemente 4 entsteht, wenn beispielsweise flüchtende Personen gegen den geschlossenen und verriegelten Flügel der Tür drängen. Dadurch darf die Sperranordnung nicht klemmen. Beim Abschalten des Elektromagneten 6 muss die Entriegelung und Freigabe des Flügels sicher erfolgen. Nachfolgend wird die Reduzierung der auf die Fallenelemente 4 durch Vorlast eingeleiteten Kraft in den verschieden Stufen der Sperranordnung detailliert beschreiben, wobei zu Beschreibung der Bewegungsabläufe die Elemente als freigegeben angenommen sind.It is essential that the multi-stage locking arrangement forces, which acts on the
Der im Gehäuse 3 geführte, mit Schieberfedern 18 in Richtung der Stulp 2 beaufschlagte Schieber 8 wird beim Öffnen des Flügels gegen die Schieberfedern 18 von der Stulp 2 weg durch die Fallenelemente 4 in das Gehäuse 3 hinein verschoben. Das Zusammenwirken der Fallenelemente 4 mit dem Schieber 8 wird nachfolgend noch näher beschrieben. Beiderseits des Schiebers 8 sind Schrägen 19 mit einem Winkel von vorteilhaft 45° angeordnet, welche mit den beiderseits des Schiebers 8 angeordneten Rasthebeln 9 zusammenwirken. Jeder der Rasthebel 9 ist in einem Drehlager 17 schwenkbar gelagert und mit einer Schenkelfeder 20 in Richtung auf den Schieber 8 beaufschlagt, wobei Schenkelfedern 20 mit unterschiedlich langen Schenkeln und unterschiedlicher Stärke in entsprechenden Aufnahmen anordenbar sind, wie es insbesondere in der
Die Krafteinleitung in den Drehkörper 10 erfolgt über eine an jedem der Rasthebel 9 angeordneten Hubschrägen 22. Der Drehkörper 10 ist im Lagersteg 12 in an den Enden angeordneten Lagerböcken 24, welche auch der Befestigung des Lagerstegs 12 am Gehäuse 3 dienen, mit Lagerstiften 25 gelagert. Der Drehkörper 10 ist weiterhin mit einer Rückstellfeder 26 beaufschlagt, die gegen den Deckel des Gehäuses 3 abgestützt ist. In alternativer Ausgestaltung kann eine Schenkelfeder, welche um einen der Lagerstifte 25 angeordnet ist, zur Rückstellung vorgesehen sein. Der schwenkbare Drehkörper 10 weist einen zurückversetzten Bereich auf, welcher durch einander gegenüberliegende Schrägflächen 27 begrenzt ist. Zwischen diesen aufeinander zuweisenden Schrägflächen 27 sind die Enden der Rasthebel 9 angeordnet, wobei die jeweilige Hubschräge 22 an der zugeordneten Schrägfläche 27 anliegt, wie es in dem Schnitt IV - IV in
Es ist eine Reduzierung von der auf die Rasthebel 9 durch den Schieber 8 eingeleiteten Kraft in die auf den Drehkörper 10 wirkende Kraft von bis zu ca. 80% möglich. Der Kraftabbau erfolgt durch Hebelwirkung, indem die Krafteinleitung auf die Rasthebel 9 nahe an den Drehlagern 17 und die Kraftweiterleitung auf den Drehkörper 10 weit entfernt von Drehpunkt 17 an den Enden der Rasthebel 9 erfolgt, sowie durch die Übertragung an den beiden Hubschrägen 22 auf die Schrägflächen 27 des Drehkörpers 10.It is possible to reduce the force applied to the locking

Der Verriegelungshebel 11 weist an seinem dem Drehlager 16 gegenüberliegenden Ende eine drehgelagerte Rolle 34 auf, die mit dem Sperrhebel 7 zusammenwirkt. Alternativ kann anstelle der Rolle 34 auch ein Gleitelement am Verriegelungshebel 11 vorgesehen oder ausgebildet sein. Die Rolle 34 liegt aufgrund der Hebelfeder 29 in Sperrstellung auf dem Sperrhebel 7 auf. Vorteilhaft wird die auf den Sperrhebel 7 wirkende Kraft durch die unterschiedlich langen wirksamen Hebel am Verrieglungshebel 11 erheblich reduziert. Die Einleitung der Kraft auf den Verriegelungshebel 11 erfolgt, wie vorbeschreiben, nahe am Drehlager 16, mit einem kurzen wirksamen Hebel, wobei der wirksame Hebel von dem Drehlager 16 bis zur Rolle 34 wesentlich länger ist. Die in den Verrieglungshebel 11 durch den Drehkörper 10 eingeleitete Kraft kann so um bis zu ca. 90% reduziert werden.The locking

Wird der Anker 35 des Elektromagneten 6 freigegen, in dem der Elektromagnet 6 abgeschaltet wird, beschleunigt die Ankerfeder 36 den Anker 35 zunächst ungehindert längs der Beschleunigungsstrecke s innerhalb des Langlochs 38 des Sperrhebels 7. Trifft der Stift 37 des Ankers 35 auf die dem Elektromagneten 6 gegenüberliegende Wandung im Langloch 38, wie in der
Die Rolle 34, welche konstruktiv im Endbereich der Laufbahn 39 des Sperrhebels 7 angeordnet ist, wird durch die Schwenkbewegung des Sperrhebels 7 frei, wodurch der Verriegelungshebel 11 durch die Hebelfeder 29 beaufschlagt in Freigabestellung schwenkt. Dadurch wird auch der Drehkörper 10 frei, und entsprechend der vorbeschriebenen Abläufe schwenken die Rasthebel 9 nach außen, wodurch auch der Schieber 8 frei wird, und die Fallenelemente 4 in den Stulp 2 bzw. das Gehäuse 3 hinein einschwenken können. Wird der Elektromagnet 6 wieder bestromt, wird der Anker 6 eingezogen und der Sperrhebel 7 zurück geschwenkt, wobei die Rolle 34 des Verriegelungshebels 11 entlang des Sperrhebels 7 geführt und der Verrieglungshebel 11 angehoben wird.The

Ist die Sperre aufgehoben, erfahren hier die äußeren Fallenelemente 4 durch die auf die Fallenelemente 4 durch die Öffnungsbewegung des Flügels eingeleitete Kraft, die durch die Anlage der Fallenelemente 4 mit dem vorbeschriebenen Schließblech eingeleitet wird, zunächst eine Schwenkbewegung, wobei der Fallensteg 41 innerhalb der Fallenführung 40 und dem mit den Schieberfedern 18 beaufschlagten Schieber 8 aufgleiten. Im weiteren Verlauf geht die Schwenkbewegung der Fallenelemente 4 in eine geradlinige Bewegung über, wobei die Fallenelemente 4 weiter in das Gehäuse 3 hinein verlagert werden, wie es in der
Die auf die Fallenelemente 4 eingeleitete Kraft kann durch die Verschiebebewegung des Fallenstegs 41 entlang der Fallenführung 40 während der Schwenkbewegung der Fallenelemente 4 um ca. 50% zu der auf den Schieber 8 wirkender Kraft reduziert werden.The force applied to the
Die Vorlast kann durch den stufenweisen Abbau auf einen Anteil von bis zu ca. 0,7% abgebaut werden, welcher noch am Sperrhebel 7 anliegt.
