Description

Die Erfindung betrifft eine Verriegelungsvorrichtung für Türen, Fenster oder dergleichen, mit einem Riegel sowie mit einem Riegelantrieb, mit dem der Riegel zwischen einer Freigabestellung und einer Verriegelungsstellung bewegbar ist, wobei der Riegelantrieb manuell und/oder motorisch betätigbar ist und zwischen dem Riegelantrieb und den Riegel ein Übersetzungsgetriebe vorgesehen ist, welches bewirkt, dass der Riegel einen größeren Weg zurücklegt, als ohne Übersetzungsgetriebe.The invention relates to a locking device for doors, windows or the like, with a latch and with a latch drive, with the latch between a release position and a locking position is movable, wherein the latch drive is manually and / or motor-operated and between the latch drive and the bolt a transmission gear is provided, which causes the bolt covers a greater distance than without transmission gear.

Es sind Verschlusseinrichtungen für eine Tür oder ein Fenster bekannt, die zur Bedienung der Verschlusseinrichtung über eine Handhabe oder einen Antriebsmotor, mindestens eine Treibriegelstange sowie einen Schnappriegel verfügen. Aufgrund des Schnappriegels kann die Tür ohne Betätigung der Treibriegelstange geschlossen werden ( DE 10 2010 001 159 A1 ). Dies ist insbesondere bei Brandschutztüren von besonderer Bedeutung, da diese im Bedarfsfall schnell und automatisch schließen müssen. Weiterhin ist wichtig, dass der Schnappriegel auch weit oder tief in das zugehörige Schließblech eingreift, so dass auch dann noch eine ausreichende Sicherheit besteht, wenn sich die Tür aufgrund der Wärmeeinwirkung ausdehnt oder verformt. Die Tür muss dann immer noch geschlossen bleiben.Locking devices for a door or a window are known, which have a handle or a drive motor, at least one drive bolt rod and a latch for operating the locking device. Due to the snap lock, the door can be closed without actuating the drive bolt rod ( DE 10 2010 001 159 A1 ). This is particularly important for fire doors of particular importance, as they need to close quickly and automatically when needed. It is also important that the latch also far or deeply engages in the associated strike plate, so that even then there is sufficient security when the door expands or deforms due to the effect of heat. The door then still has to remain closed.

Aus der DE 10 2008 032 120 A1 ist eine Verriegelungsvorrichtung für Türen, Fenster und dergleichen, offenbart, die eine Betätigungseinrichtung, eine Antriebsstange und ein Zwischengetriebe aufweist. Die dieser Verriegelungsvorrichtung zugrunde liegende Aufgabe besteht darin, den Kraftaufwand an der Betätigungseinrichtung zu vermindern. Dies wird erreicht, indem das Getriebe als Untersetzungsgetriebe aufgebaut ist. Vorzugsweise ist das Getriebe zwischen einer Antriebsstange und dem Riegel angeordnet.From the DE 10 2008 032 120 A1 discloses a locking device for doors, windows and the like, having an actuator, a drive rod and an intermediate gear. The This object of this locking device is to reduce the force on the actuator. This is achieved by the transmission is constructed as a reduction gear. Preferably, the transmission is arranged between a drive rod and the latch.

Die US 5 020 836 A zeigt eine Verriegelungsvorrichtung für Türen, Fenster oder dergleichen mit einem Riegel sowie mit einem Riegelantrieb, mit dem der Riegel zwischen einer Freigabestellung und einer Verriegelungsstellung bewegbar ist. Der Riegelantrieb ist manuell betätigbar. Zwischen dem Riegelantrieb und dem Riegel ist ein Übersetzungsgetriebe vorgesehen, welches bewirkt, dass der Riegel einen größeren Weg zurücklegt, als ohne Übersetzungsgetriebe.The US 5 020 836 A shows a locking device for doors, windows or the like with a latch and with a latch drive, with which the latch between a release position and a locking position is movable. The bolt drive can be operated manually. Between the latch drive and the latch, a transmission gear is provided, which causes the latch covers a greater distance than without transmission gear.

Der Erfindung liegt die Aufgabe zugrunde, eine Verschlusseinrichtungen bereit zu stellen, die einer Brandschutztür eine größere Sicherheit verleiht.The invention has for its object to provide a closure devices that gives a fire door a greater security.

Diese Aufgabe wird bei einer Verriegelungsvorrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass der Riegelantrieb als Treibriegelstange ausgebildet ist, dessen Ende geschlitzt oder C-förmig ausgestaltet ist und einen als Übersetzungsgetriebe wirkenden Hebel umgreift, der mit seinem einen Ende schwenkbar in einem Schwenklager am Gehäuse gelagert ist und das andere Ende in einem Schwenklager und einem Langloch am Riegel angreift.This object is achieved according to the invention in a locking device of the type mentioned in that the latch drive is designed as a drive bolt rod, the end slotted or C-shaped and engages around a lever acting as a transmission gear, which pivotally with its one end in a pivot bearing on the housing is mounted and the other end engages in a pivot bearing and a slot on the bolt.

Die erfindungsgemäße Verschlusseinrichtungen kann z.B. über eine Handhabe bedient werden, über die mindestens eine Treibriegelstange betätigt wird, mit welcher wiederum ein Riegel bewegt wird. Zwischen der Treibriegelstange und dem Riegel ist ein Übersetzungsgetriebe vorgesehen, das vorzugsweise einen kleinen Weg der Treibriegelstange in einen größeren Weg, nämlich den Hub des Riegels umwandelt, also eine Übersetzung darstellt. Damit werden bei großen Flügeln trotz baugleicher Schlösser ausreichend große Hübe und Eingriffstiefen des Riegels in die Schließbleche gewährleistet, so dass bei einem Verziehen der Tür im Brandfall oder grundsätzlich als Einbruchschutz (Versicherungsschutz) ein hinreichend tiefes Eingreifen des Riegels in das Schließblech erfolgt. Von großem Vorteil ist, dass Türen mit herkömmlichen Verriegelungseinrichtungen relativ einfach umgerüstet werden können, indem lediglich die vorherige Einrichtung gegen die neue, erfindungsgemäße Verrieglungseinrichtung ausgetauscht wird.The locking devices according to the invention can be operated, for example, via a handle via which at least one drive bolt rod is actuated, with which in turn a bolt is moved. Between the floating bolt bar and the latch, a transmission gear is provided, which is preferably a small way the shoot bolt in a larger way, namely the stroke of the bolt converts, so represents a translation. Thus, despite large locks despite sufficiently identical locks sufficiently large strokes and depths of engagement of the bolt guaranteed in the strike plates, so that when a warping of the door in case of fire or basically as burglar protection (insurance coverage) is a sufficiently deep engagement of the bolt in the strike plate. Of great advantage is that doors with conventional locking devices can be relatively easily converted by only the previous device is replaced with the new, inventive Verrieglungseinrichtung.

Wie bereits erwähnt ist der Riegelantrieb als Treibstange oder Treibriegelstange ausgebildet. Diese kann entweder manuell oder motorisch betätigt werden. Außerdem kann eine nach oben wirkende und eine nach unten wirkende Treibriegelstange vorgesehen sein, so dass in den Sturz und in den Boden eingreifende Schnapprigel betätigt werden können.As already mentioned, the bolt drive is designed as a drive rod or drive bolt bar. This can be operated either manually or by motor. In addition, an upwardly acting and a downwardly acting floating bolt bar can be provided so that engaging in the camber and in the ground snap prong can be operated.

Ein automatisches Schließen der Tür wird dadurch ermöglicht, dass der Riegel als Schnappriegel ausgebildet ist. Dies ist insbesondere bei Brandschutztüren erforderlich, deren Schließen automatisch ausgelöst wird.An automatic closing of the door is made possible by the fact that the bolt is designed as a latch. This is particularly necessary for fire doors whose closing is triggered automatically.

Um zu gewährleisten, dass der Riegel immer seine Verriegelungsstellung einnimmt, wird der Riegel von einer Ausschubfeder in Richtung der Verriegelungsstellung gedrängt. Diese Feder kann als Schenkelfeder oder als Wendelfeder ausgebildet sein und sich am Gehäuse abstützen.To ensure that the latch always assumes its locking position, the latch is urged by a Ausschubfeder in the direction of the locking position. This spring can be designed as a leg spring or as a coil spring and be supported on the housing.

Dadurch, dass der Riegel in Richtung der Freigabestellung einen Freilauf aufweist, kann er ohne Betätigung der Treibriegelstange beim Schließen der Tür in das Gehäuse eingeschoben werden.The fact that the latch has a freewheel in the direction of the release position, it can without actuation of the Dead bolt should be inserted into the housing when closing the door.

Eine bevorzugte Ausführungsform löst diese Aufgabe mittels eines Hebels, wobei der längere Arm den Schnappriegel antreibt und der kürzere Arm von der Treibriegelstange angetrieben wird. Auf diese Weise wird ein bestimmter Weg der Treibriegelstange in einen größeren Weg des Schnappriegels umgewandelt.A preferred embodiment solves this problem by means of a lever, wherein the longer arm drives the latch and the shorter arm is driven by the drive bolt bar. In this way, a certain path of the floating bolt rod is converted into a larger path of the latch.

Ist, gemäß einer Variante der Erfindung, der Hebel einseitig im Gehäuse der Verriegelungsvorrichtung schwenkbar gelagert, dann sieht eine Weiterbildung vor, dass der Riegelantrieb zwischen dem Schwenklager und dem Riegel am Hebel angreift. Eine höhere Varianz einerseits, und eine optimales Anpassung der Verriegelungsvorrichtung an unterschiedliche Türen andererseits wird dadurch erreicht, dass der Angriffspunkt des Riegelantriebes am Hebel, der Angriffspunkt des Hebels am Riegel oder die Lage des Schwenklagers im Gehäuse variabel einstellbar sind. Dadurch kann die Hublänge des Riegels exakt auf die gewünschte Länge eingestellt werden.Is, according to a variant of the invention, the lever mounted on one side in the housing of the locking device pivotally, then provides a development that the bolt drive between the pivot bearing and the bolt engages the lever. A higher variance on the one hand, and an optimal adaptation of the locking device to different doors on the other hand is achieved in that the point of the latch drive on the lever, the point of the lever on the bolt or the position of the pivot bearing in the housing are variably adjustable. As a result, the stroke length of the bolt can be set exactly to the desired length.

Ein weiterer Vorteil besteht darin, dass die Treibriegelstange und der Riegel in gleiche Richtungen verschoben werden. Dadurch können herkömmliche Verriegelungsvorrichtungen problemlos gegen die erfindungsgemäße Verriegelungsvorrichtung ausgetauscht werden.Another advantage is that the floating bolt bar and the bolt are moved in the same directions. As a result, conventional locking devices can be easily replaced with the locking device according to the invention.

Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen sowie der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung ein besonders bevorzugtes Ausführungsbeispiel im Einzelnen beschrieben ist. Dabei können die in der Zeichnung sowie in der Beschreibung erwähnten Merkmale jeweils einzeln für sich oder in beliebiger Kombination erfindungswesentlich sein.Further features of the invention will become apparent from the subclaims and the following description in which a particularly preferred embodiment is described in detail with reference to the drawing. The features mentioned in the drawing and in the description can each be essential to the invention individually or in any desired combination.

In der Zeichnung zeigen:

Figur 1:

Figur 2
die Vorrichtung gemäß Figur 1 in der Offen- oder Freigabestellung.
In the drawing show:
FIG. 1:
a longitudinal section through an embodiment of the locking device according to the invention in the locking position; and
FIG. 2
the device according to FIG. 1 in the open or release position.

In der Figur 1 ist mit dem Bezugszeichen 10 ein bevorzugtes Ausführungsbeispiel einer Verriegelungsvorrichtung dargestellt, welche eine Verriegelungsstellung einnimmt, in welcher ein Riegel 12 aus einem Gehäuse 14 heraustritt. Dieser greift mit einem mit 16 bezeichneten Hub in ein rahmen- oder bodenseitiges Schließblech 18 ein. Der Riegel 12 wird von einer Ausschubfeder 20 in Form einer Schenkelfeder 22, die sich an der Rückwand des Gehäuses 14 sowie an einem Vorsprung des Riegels 12 abstützt, aus dem Gehäuse 14 in die Verriegelungsstellung gedrängt. Außerdem wird der Riegel 12 von einer Schubführung 24 längsverschieblich gehalten.In the FIG. 1 is the reference numeral 10, a preferred embodiment of a locking device shown, which occupies a locking position in which a bolt 12 emerges from a housing 14. This engages with a designated 16 stroke in a frame or bottom-side strike plate 18 a. The latch 12 is urged by a Ausschubfeder 20 in the form of a leg spring 22, which is supported on the rear wall of the housing 14 and on a projection of the bolt 12, out of the housing 14 in the locking position. Furthermore the bolt 12 is held by a thrust guide 24 longitudinally displaceable.

In das Gehäuse 14 greift außerdem eine als Riegelantrieb 25 dienende Treibriegelstange 26 ein, die in Richtung des Doppelpfeils 28 verschiebbar ist. Das Ende 30 der Treibriegelstange 26 ist geschlitzt oder C-förmig ausgestaltet und umgreift einen als Übersetzungsgetriebe 32 wirkenden Hebel 34. Dieser Hebel 34 ist mit seinem einen Ende schwenkbar in einem Schwenklager 36 am Gehäuse 14 gelagert, wohingegen das andere Ende in einem Schwenklager 38 (und einem Langloch) am Riegel 12 angreift. Dazwischen greift die Treibriegelstange 26 an und unterteilt den Hebel 34 derart, dass ein erster Hebelarm 40 und ein zweiter Hebelarm 42 gebildet werden. Der zweite Hebelarm 42 erstreckt sich zwischen den beiden Schwenklagern 36 und 38.In the housing 14 also engages serving as a latch drive 25 driving bolt rod 26 which is displaceable in the direction of the double arrow 28. The end 30 of the floating bolt bar 26 is slotted or C-shaped and surrounds a lever 34 acting as a transmission gear 34. This lever 34 is pivotally mounted at one end in a pivot bearing 36 on the housing 14, whereas the other end in a pivot bearing 38 (FIGS. and a slot) on the latch 12 attacks. In between, the drive bolt rod 26 engages and divides the lever 34 such that a first lever arm 40 and a second lever arm 42 are formed. The second lever arm 42 extends between the two pivot bearings 36 and 38th

Wird die Tür geschlossen, dann drückt die Kante des Schließblechs 18 den Riegel 12 aufgrund seiner Riegelschräge 44 ins Gehäuse 14 ein (siehe Figur 2). Nachdem die Tür ihre Schließlage eingenommen hat, drückt die Ausschubfeder 20 den Riegel 12 in die Riegelaufnahme 46, so dass der Riegel 12 die in der Figur 1 dargestellte Lage einnimmt. Der Riegel 12 ist also ein Schnappriegel.If the door is closed, then presses the edge of the lock plate 18, the latch 12 due to its locking bevel 44 into the housing 14 (see FIG. 2 ). After the door has taken its closed position, the Ausschubfeder 20 presses the bolt 12 in the latch receptacle 46, so that the latch 12 in the FIG. 1 position shown assumes. The latch 12 is thus a latch.

Ein manuelles oder motorisches Öffnen oder Entriegeln erfolgt über die Treibriegelstange 26, die eine bestimmte Wegstrecke aus dem Gehäuse 14 gezogen wird. Dabei wird der Hebel 34 um das Schwenklager 36 verschwenkt, wodurch der Riegel 12, an dem das andere Ende des Hebels 12 angreift, in das Gehäuse 14 eingezogen wird. Die zurückgelegte Wegstrecke der Treibriegelstange 26 wird dabei in einen Hub 16 gemäß dem Hebelverhältnis der Hebel 40 und 42, nämlich im Verhältnis Hebel 42/Hebel 40 übersetzt. Trotz geringer Wegstrecke der Treibriegelstange 26 kann also ein relativ großer Hub 16 für den Riegel 12 erzielt werden. Oder bei herkömmlicher Wegstrecke der Treibriegelstange 26 kann der Hub 16 des Riegels 12 entsprechend vergrößert werden.A manual or motorized opening or unlocking via the drive bolt rod 26, which is pulled a certain distance from the housing 14. In this case, the lever 34 is pivoted about the pivot bearing 36, whereby the latch 12, on which the other end of the lever 12 engages, is drawn into the housing 14. The covered distance of the drive bolt 26 is translated into a stroke 16 according to the lever ratio of the levers 40 and 42, namely in the ratio lever 42 / lever 40. Despite a small distance of the drive bolt rod 26 can therefore be a relative large stroke 16 can be achieved for the bar 12. Or in the conventional path of the drive bolt 26, the stroke 16 of the bolt 12 can be increased accordingly.
