Ein Schaltschloss der vorbeschriebenen Art ist bekannt aus der EP 0 348 971 B1 . Das Schaltschloss dient der Führung und der Bewegungshemmung eines Treibstangenverschlusses. Derartige Treibstangenverschlüsse finden üblicherweise an den Standflügeln von zweiflügeligen Türen Verwendung. Der Gangflügel dieser Tür ist durch Betätigen eines gewöhnlichen Einsteckschlosses öffenbar. Hierzu muss die Falle des dem Gangflügel zugeordneten Schlosses und gegebenenfalls auch ein Riegel aus einem Schließblech, welches dem Standflügel zugeordnet ist, zurückgezogen werden. Um den Standflügel in seiner geschlossenen Stellung zu halten, treten aus der oberen Horizontalkante und der unteren Horizontalkante des Standflügels Riegelstangen aus, die mit ihren Riegel-Enden in Schließbleche eintreten, wobei ein Schließblech im Boden eingelassen ist und ein Schließblech im oberen Türrahmenschenkel sitzt. Durch Betätigen einer dem Standflügel zugeordneten Handhabe, beispielsweise einer Drehhandhabe, werden die beiden Riegelstangen gegenläufig aus den Schließblechen herausgezogen. Um die Riegelstangen in der Offenstellung zu halten, wird ein gattungsgemäßes Treibriegelschaltschloss verwendet. Dieses wird der oberen Riegelstange zugeordnet und bildet zunächst die Führung des Endes der Riegelstange aus und mit einem Klemmkörper, dessen Halterung in der Offenstellung, damit insbesondere die untere Riegelstange nicht aus der Unterseite der Tür heraustritt, was zu einer Beschädigung des Fußbodens führen könnte.A switching mechanism of the type described above is known from the EP 0 348 971 B1 , The switch lock serves to guide and the movement inhibition of a drive rod lock. Such espagnolette closures are commonly used on the inactive wings of double-leaf doors. The active leaf of this door can be opened by pressing an ordinary mortise lock. For this purpose, the case of the active leaf associated lock and possibly also a bolt of a strike plate, which is associated with the inactive leaf, must be withdrawn. To keep the inactive leaf in its closed position, emerging from the upper horizontal edge and the lower horizontal edge of the passive leaf locking rods, which enter with their bolt ends in strike plates, a strike plate is embedded in the ground and a strike plate in the upper door frame leg sits. By pressing a handgrip associated with the stationary leaf, for example a rotary handle, the two locking bars are pulled in opposite directions out of the striking plates. In order to keep the locking bars in the open position, a generic Treibriegelschaltschloss is used. This is assigned to the upper locking bar and initially forms the leadership of the end of the locking bar and with a clamping body, the holder in the Open position, so that in particular the lower locking bar does not emerge from the bottom of the door, which could lead to damage to the floor.

Das gattungsgemäße Treibstangenschaltschloss besitzt eine federbelastete Klemmplatte, die den Treibriegel mit einem Klemmauge umgreift und ihn in beliebigen Einfahrstellungen hemmen kann.The generic espagnolette lock has a spring-loaded clamping plate, which surrounds the drive bolt with a clamping eye and can inhibit it in any Einfahrstellungen.

Die EP 0 859 106 A1 beschreibt ebenfalls ein Treibriegelschaltschloss mit einem Auslöser und zwei sich diametral gegenüberliegenden Klemmkörpern.The EP 0 859 106 A1 also describes a drive bolt lock with a trigger and two diametrically opposed sprags.

Bei dem Treibstangenschaltschloss gemäß EP 0712 984 A1 ist ein Klemmschieber vorgesehen, der in einer Bereitschaftsstellung die Verlagerbarkeit der Riegelstange hemmt. Die DE 197 27 365 C1 beschreibt zwei sich gegenüberliegende Klemmstifte, die durch Verschieben einer Hülse in und außer Wirkung gebracht werden können.In the espagnolette lock according to EP 0712 984 A1 a clamping slide is provided which inhibits the displaceability of the locking bar in a standby position. The DE 197 27 365 C1 describes two opposing clamping pins, which can be brought into and out of action by moving a sleeve.

Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Schloss gebrauchsvorteilhaft weiterzubilden. Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung.The invention has the object of developing the generic lock benefits advantageous. The object is achieved by the invention specified in the claims.

Zunächst und im Wesentlichen wird vorgeschlagen, dass das Klemmelement eine Klemmklinke ist. Diese ist um eine quer zur Verlagerungsrichtung gerichtete Schwenkachse schwenkbar einem Schlossgehäuse zugeordnet. Die Schwenkachse liegt versetzt neben der Riegelstange. Die Klinke besitzt eine im Wesentlichen auf einer Spiralkurve bezogen auf die Schwenkachse verlaufende Klemmfläche, die von einer Feder, insbesondere Drehschenkelfeder gegen die Außenmantelfläche der Riegelstange gedrückt wird. Die dabei entstehende Tangentialkraft ist in Ausfahrrichtung der Riegelstange gerichtet. Die Klemmklinke besitzt einen radial abragenden Klemmarm, dessen Stirnfläche die Klemmfläche ausbildet. Diese kann mit einer Verzahnung versehen sein. Der Stulp besitzt eine vorzugsweise im Wesentlichen einen rechteckigen Grundriss aufweisende Führungsöffnung. Der Auslöser ist dort vorteilhaft mit einem rechteckigen Führungsabschnitt gelagert. Der Führungsabschnitt bildet eine Höhlung aus, die in einer schräg verlaufenden Auflaufschrägen mündet. In dieser Höhlung ist die Riegelstange geführt. Bevorzugt bildet der Auslöser mit einer unteren Randkante des Führungsabschnittes eine Schaltkante aus, die bei einer Verlagerung des Auslösers von einer Bereitschaftsstellung in eine Auslösestellung eine Schaltflanke der Klinke beaufschlagt. Die Schaltflanke wird dabei vom Klinkenarm ausgebildet. Wenn der Auslöser durch Auflaufen der Auflaufschrägen an einem Gegenschließteil parallel zur Erstreckungsrichtung der Riegelstange und entgegen der Ausfahrrichtung verlagert wird, wird die Klinke aus ihrer Klemmstellung verschwenkt. Die Klemmfläche löst sich von der Mantelfläche der Riegelstange, die einen kreisrunden Querschnitt aufweisen kann, und gibt sie zur Verlagerung durch die Führungsbohrung des Auslösers frei, so dass sie in das Gegenschließteil einfahren kann. Einhergehend damit fährt auch die untere Riegelstange in das ihr vorzugsweise zugeordnete Schließblech. Bevorzugt dient zur Führung des Auslösers ein Führungszapfen, der in eine Führungsnut der Gehäusewand des Schlossgehäuses geführt ist. In einer Ausführungsform stützt sich die Schwenkachse mit ihren beiden Endabschnitten am Gehäuse ab. Hierzu liegen die beiden voneinander wegweisenden Endabschnitte in Lagerausnehmungen zweier parallel und beabstandet zueinander verlaufenden Gehäusewänden. Die Schenkelfeder kann sich mit einem Schenkel an einem Zapfen der Sperrklinke und mit ihrem anderen Schenkel an einer Gehäusewandung abstützen.First and foremost, it is proposed that the clamping element is a clamping pawl. This is assigned to a lock housing pivotable about a pivot axis directed transversely to the displacement direction. The pivot axis is offset next to the locking bar. The latch has a substantially on a spiral curve with respect to the pivot axis extending clamping surface which is pressed by a spring, in particular rotary leg spring against the outer circumferential surface of the locking bar. The resulting tangential force is directed in the extension direction of the locking bar. The clamping pawl has a radially projecting clamping arm whose end face the Forming clamping surface. This can be provided with a toothing. The forend has a preferably essentially a rectangular plan having guide opening. The trigger is advantageous stored there with a rectangular guide portion. The guide portion forms a cavity, which opens into a sloping ramps. In this cavity, the locking bar is guided. Preferably, the trigger forms with a lower peripheral edge of the guide portion of a switching edge, which acts on a shift of the trigger from a standby position to a release position, a switching edge of the pawl. The switching edge is formed by the pawl. If the trigger is displaced by running up the ramps on a counter-closing part parallel to the extension direction of the locking bar and against the extension direction, the pawl is pivoted out of its clamping position. The clamping surface releases from the lateral surface of the locking bar, which may have a circular cross-section, and releases them for displacement through the guide bore of the trigger, so that they can retract into the counter-closing part. Along with it also moves the lower locking bar in her preferably assigned strike plate. Preferably serves to guide the trigger a guide pin which is guided in a guide groove of the housing wall of the lock housing. In one embodiment, the pivot axis is supported with its two end portions on the housing. For this purpose, the two end portions facing away from each other are in bearing recesses of two parallel and spaced housing walls. The leg spring can be supported with one leg on a pin of the pawl and with its other leg on a housing wall.

Das Schubstangenschaltschloss, wie es in den Zeichnungen dargestellt ist, wird an dem Standflügel einer aus Gangflügel und Standflügel bestehenden zweiflügeligen Tür verwendet. Es sitzt in einer Ausnehmung in der oberen, horizontal verlaufenden Schmalseite des Standflügels. In der Geschlossenstellung des Standflügels liegt dem Schubstangenschaltschloss ein Schließblech gegenüber, welches fest im oberen Rahmenschenkel des Türrahmens befestigt ist. Das Schließblech besitzt eine Eintrittsöffnung, in welche dieRiegelstange 6 einfahren kann.The push rod switch lock, as shown in the drawings, is used on the inactive leaf of a double-leaf door consisting of active leaf and passive leaf. It sits in a recess in the upper, horizontally extending narrow side of the inactive leaf. In the closed position of the inactive leaf, the push rod switch lock faces a strike plate, which is fixed in the upper frame leg of the door frame. The strike plate has an inlet opening into which the locking bar 6 can enter.

Das Schloss besitzt ein Schlossgehäuse 1, welches eine quaderförmige Gestalt aufweist und welches rückseitig an einem Stulp 2 befestigt ist. Der Stulp 2 besitzt zwei Befestigungsöffnungen 8 und eine einen rechteckigen Grundriss aufweisende zwischen den Befestigungsöffnungen 8 angeordnete Führungsöffnung 17.The lock has a lock housing 1, which has a cuboid shape and which is fastened on the back to a face plate 2. The forend 2 has two attachment openings 8 and a guide opening 17, which has a rectangular outline and is arranged between the attachment openings 8.

In der Führungsöffnung 17 ist ein Auslöser 5 verschieblich gelagert. Der Auslöser 5 besitzt eine schräg verlaufende Auflaufschräge 13, die sich in der Bereitschaftsstellung des Auslösers 5 oberhalb des Stulps 2 befindet. An dem die Auflaufschräge 13 ausbildenden Abschnitt des Auslösers 5 schließt sich ein im Wesentlichen quaderförmiger Führungsabschnitt 18 an, der in der Führungsöffnung 17 geführt ist. Von dem in das Schlossgehäuse 1 hineinragenden Führungsabschnitt 18 ragen zwei sich gegenüberliegende Führungszapfen 16 ab, die in Führungsnuten der Gehäuseinnenwand des Schlossgehäuses 1 geführt sind. Der Führungsabschnitt 18 besitzt eine einen kreisrunden Querschnitt aufweisende Führungsbohrung 12, die in der Auflaufschräge 13 mündet. In dieser Führungsbohrung 12 ist das Ende einer einen kreisrunden Querschnitt aufweisenden Riegelstange 6 geführt. Die Riegelstange 6 ist mit einem nicht dargestellten Antriebsmechanismus verbunden, mit dem auch eine untere Riegelstange verbunden ist, so dass die Riegelstangen gegenläufig ausfahren können. Dies kann über einen vorgespannten Kraftspeicher erfolgen.In the guide opening 17, a trigger 5 is slidably mounted. The trigger 5 has an inclined run-on slope 13, which is located in the ready position of the trigger 5 above the cuff 2. At the bevel 13 forming portion of the trigger 5 is followed by a substantially parallelepiped-shaped guide portion 18, which is guided in the guide opening 17. From the protruding into the lock housing 1 guide portion 18 protrude two opposing guide pin 16, which are guided in guide grooves of the housing inner wall of the lock housing 1. The guide portion 18 has a circular cross-section having guide bore 12, which opens into the ramp be 13. In this guide bore 12, the end of a circular cross-section having a locking bar 6 is guided. The locking bar 6 is connected to a drive mechanism, not shown, with which a lower locking bar is connected, so that the locking bars can extend in opposite directions. This can be done via a prestressed energy storage.

Um zu verhindern, dass die Riegelstange 6 bei nicht geschlossenem Standflügel aus der Führungsbohrung 12 ausfährt, besitzt das Schloss ein Klemmelement 3, welches die Form einer Klinke aufweist. Die Klinke ist um eine Schwenkachse 4 im Gehäuse 1 schwenkbar gelagert, wobei die beiden voneinander wegweisenden Endabschnitte der Schwenkachse 4 in parallel und beabstandet zueinander verlaufenden Gehäusewänden gelagert sind. Die Klinke 3 befindet sich etwa in der axialen Mitte der Schwenkachse 4 und wird von zwei auf jeder der beiden Klinkenbreitseiten angeordneten Schenkelfedern 7 in die Klemmstellung beaufschlagt. Hierzu stützt sich ein Schenkel der Schenkelfeder 7 an einer Gehäusewandung 10 ab, mit der das Gehäuse 1 an der Rückseite des Stulps befestigt ist. Der andere Schenkel der Schenkelfeder 7 stützt sich an einem Zapfen 9 des Klinkenarms ab und beaufschlagt eine im Wesentlichen auf einer Spiralkurve um die Schwenkachse 4 verlaufende Klemmfläche 11 gegen die Mantelfläche der Riegelstange 6.In order to prevent the locking bar 6 from extending out of the guide bore 12 when the inactive leaf is not closed, the lock has a clamping element 3, which has the shape of a pawl. The pawl is pivotally mounted about a pivot axis 4 in the housing 1, wherein the two facing away from each other End portions of the pivot axis 4 are mounted in parallel and spaced apart extending housing walls. The pawl 3 is located approximately in the axial center of the pivot axis 4 and is acted upon by two arranged on each of the two Klinkenbreitseiten leg springs 7 in the clamping position. For this purpose, a leg of the leg spring 7 is supported on a housing wall 10, with which the housing 1 is attached to the back of the forend. The other leg of the leg spring 7 is supported on a pin 9 of the pawl arm and acts on a substantially on a spiral curve about the pivot axis 4 extending clamping surface 11 against the lateral surface of the locking bar. 6

Die von der ein Querrillenprofil aufweisenden Klemmfläche 11 auf die Riegelstange 6 aufgebrachte Tangentialkraft wirkt in Ausfahrrichtung der Riegelstange 6, also nach oben. Die Klemmwirkung bewirkt, dass die Riegelstange 6 nicht nach oben durch die Führungsbohrung 12 verlagert werden kann.The tangential force applied by the transverse groove profile on the clamping surface 11 to the locking bar 6 acts in the extension direction of the locking bar 6, that is to say upwards. The clamping effect causes the locking bar 6 can not be displaced upwardly through the guide bore 12.

Die Gehäuseunterseite 20 besitzt eine kreisrunde Öffnung 19, die mit der Führungsbohrung 12 fluchtet und durch welche die Riegelstange 6 hindurchgreift.The housing bottom 20 has a circular opening 19 which is aligned with the guide bore 12 and through which the locking bar 6 engages.

Die Funktionsweise des Schaltschlosses ist die folgende:

  • In einer Bereitschaftsstellung (Figuren 1 bis 5), die einer Offenstellung entspricht, ist die Riegelstange 6 maximal tief eingezogen und liegt unterhalb der Auflaufschräge 13. Die Auflaufschräge 13 ragt aus der Oberseite des Stulps 2 heraus und kann beim Schließen des Standflügels gegen ein Schließblech treten. Dies hat zur Folge, dass der Auslöser 3 in das Schlossgehäuse 1 hineinverlagert wird. Einhergehend damit beaufschlagt eine Schaltkante 14, die von einer unterseitigen Stufe des Auslösers 5 gebildet ist, eine Schaltflanke 15 der Klinke 3. Die Schaltflanke 15 wird von einer Seitenwandung des Klinkenarmes ausgebildet. Im Zuge der Abwärtsverlagerung des Auslösers 5 wird die Klemmklinke 3 gegen die Rückstellkraft der Schenkelfedern 7 in eine Freigabestellung verlagert, so dass die Riegelstange 6 durch die Führungsbohrung 12 herausfahren kann. Im Zuge dieser Schwenkverlagerung der Klinke 3 entfernt sich die Klemmfläche 11 von der Mantelfläche der Riegelstange 6.
The operation of the switch lock is the following:
  • In a standby position ( FIGS. 1 to 5 ), which corresponds to an open position, the locking bar 6 is retracted maximally deep and is below the ramp 13. The ramp 13 protrudes from the top of the forend 2 and can occur when closing the passive leaf against a strike plate. As a result, the trigger 3 is moved into the lock housing 1. Along with this, a switching edge 14, which is formed by a lower-side stage of the trigger 5, acts on a switching edge 15 of the pawl 3. The switching flank 15 is formed by a side wall of the pawl arm. In the course of the downward displacement of the trigger 5, the clamping pawl 3rd shifted against the restoring force of the leg springs 7 in a release position, so that the locking bar 6 can drive out through the guide bore 12. In the course of this pivotal displacement of the pawl 3, the clamping surface 11 moves away from the lateral surface of the locking bar. 6

In der Geschlossenstellung des Standflügels (Figuren 6 bis 10) verbleibt der Auslöser 5 in der gehäuseeinwärtigen Auslösestellung und hält die Klinke 3 in der Freigabestellung. In dieser Stellung kann die Riegelstange 6 frei durch die Führungsbohrung 12 verlagert werden, wenn eine diesbezügliche Handhabe betätigt wird.In the closed position of the inactive leaf ( FIGS. 6 to 10 ) the trigger 5 remains in the housing-in-turn release position and holds the pawl 3 in the release position. In this position, the locking bar 6 can be freely displaced by the guide bore 12, when a related handle is actuated.

Wird bei in Offenstellung gebrachten Riegelstangen 6 der Standflügel geöffnet, so wird der Auslöser 5 durch die Kraft der gespannten Schenkelfeder 7 in die Bereitschaftsstellung verlagert. Die Schenkelfeder 7 greift hierzu am Zapfen 9 des Klinkenarmes an. Die Schaltflanke 15 beaufschlagt die Schaltkante 14, so dass der Auslöser 5 nach oben verlagert wird. Der Auslöser 5 wird somit von der Kraft der Klemmelementfeder 7 in der Bereitschaftsstellung gehalten und von der Klemmelementfeder 7 auch von der Auslösestellung in die Bereitschaftsstellung verlagert. Dabei legt sich die Klemmfläche 11 sperrend gegen die Außenwandung der Riegelstange 6.Is opened in the open position locking bars 6 of the inactive leaf, the trigger 5 is displaced by the force of the tensioned leg spring 7 in the ready position. The leg spring 7 attacks this on the pin 9 of the ratchet arm. The switching edge 15 acts on the switching edge 14, so that the trigger 5 is displaced upwards. The trigger 5 is thus held by the force of the clamping element spring 7 in the standby position and displaced by the clamping element spring 7 from the release position to the standby position. In this case, the clamping surface 11 sets blocking against the outer wall of the locking bar. 6
