Description

Die Erfindung betrifft ein Schlossgetriebe für den Flügel von Türen, mit mindestens einer Treibstange, die mindestens ein Riegelelement trägt, parallel zur Stulpschiene des Schlossgetriebes angeordnet und verschiebbar ist und durch eine Federkraft in die Schliessstellung gedrückt wird, einem auf die Treibstange wirkenden Antriebselement zum Verschieben der Treibstange gegen die Federkraft in die Öffnungsstellung, einer mit der Treibstange zusammenwirkenden Arretiereinrichtung, die in Öffnungsstellung der Treibstange selbsttätig einrastet und diese in Öffnungsstellung arretiert und beim Schliessen des Flügels durch den Feststellrahmen zum Ausrasten gebracht wird, und einem mittels eines Schlüssels quer zur Treibstange verschiebbaren Riegel (DE-C-1 062143).The invention relates to a lock gear for the wing of doors, with at least one drive rod, which carries at least one locking element, is arranged parallel to the faceplate of the lock gear and is displaceable and is pressed into the closed position by a spring force, a drive element acting on the drive rod for displacing the Push rod against the spring force in the open position, a locking device which interacts with the push rod, which engages automatically in the open position of the push rod and locks it in the open position and disengages when the sash is closed by the locking frame, and a bolt which can be moved transversely to the drive rod by means of a key (DE-C-1 062143).

Bei bekannten Beschlägen wird die Treibstange mittels der Türklinke betätigt, die zum Zurückziehen der Falle des Schlossgetriebes dient. Mit dieser Klinke ist ein schwenkbares Antriebselement gekoppelt, welches auf die Treibstange einwirkt. Die Betätigung des Riegels mittels Schlüssel ist völlig unabhängig von der Betätigung der Treibstange.In known fittings, the drive rod is actuated by means of the door handle, which serves to retract the latch of the lock gear. A pivotable drive element is coupled to this pawl, which acts on the drive rod. The operation of the bolt with the key is completely independent of the operation of the drive rod.

Bei einem Beschlag dieser Art wird beim Betätigen der Klinke zum Entriegeln und Öffnen des Flügels die Treibstange in ihre Öffnungsstellung bewegt und dort durch eine Arretiervorrichtung arretiert. Diese Arretierung bleibt auch dann erhalten, wenn bei geöffnetem Flügel die Klinke auf- und abbewegt wird. Beim Schliessen, d.h. Zudrücken des Flügels, schlägt ein Hebel der Arretiervorrichtung am feststehenden Rahmen an und löst die Arretierung aus, so dass die Treibstange durch eine Federbelastung selbsttätig in die Schliessstellung zurückkehrt und die Riegelelemente in die zugeordneten Schliessbleche des feststehenden Rahmens einrasten. Man erhält somit beim Schliessen des Türflügels eine automatische Verriegelung nicht nur mittels der gewöhnlichen Schlossfalle, sondern zusätzlich mittels der an der Treibstange sitzenden Riegelelemente.With a fitting of this type, when the pawl is actuated to unlock and open the sash, the connecting rod is moved into its open position and locked there by a locking device. This locking is retained even if the pawl is moved up and down with the sash open. When closing, i.e. Pressing the wing, a lever of the locking device strikes the fixed frame and triggers the locking, so that the drive rod automatically returns to the closed position due to a spring load and the locking elements snap into the assigned locking plates of the fixed frame. When the door leaf is closed, automatic locking is thus obtained not only by means of the usual lock latch, but also by means of the locking elements located on the drive rod.

Ein mit diesem bekannten Beschlag versehener Türflügel kann aber nur dann von beiden Seiten geöffnet werden, wenn er auf beiden Seiten eine Klinke oder einen Drehgriff aufweist. Es ist aber häufig, insbesondere bei Aussentüren, erwünscht, dass auf der einen Seite, nämlich der Aussenseite, keine Klinke vorhanden ist, sondern der Türflügel mittels eines Schlüssels geöffnet werden kann.A door leaf provided with this known fitting can only be opened from both sides if it has a latch or a turning handle on both sides. However, it is often desirable, particularly in the case of exterior doors, that there is no latch on one side, namely the exterior, but that the door leaf can be opened by means of a key.

Es ist daher die Aufgabe der Erfindung, einen Beschlag der genannten Art so auszubilden, dass er mittels eines Schlüssels auch ohne Betätigung einer Klinke in Öffnungsstellung gebracht werden kann.It is therefore the object of the invention to design a fitting of the type mentioned in such a way that it can be brought into the open position by means of a key even without actuating a latch.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Riegel das Antriebselement zum Verschieben der Treibstange bildet und mit der Treibstange durch eine die in Öffnungsrichtung des Riegels wirkende Verschiebekraft in eine in Öffnungsrichtung der Treibstange wirkende Verschiebekraft umlenkende Antriebsübertragung gekuppelt ist und dass in der Antriebsübertragung ein nur in Richtung der Öffnungsbewegung des Riegels kraftübertragendes, bei Erreichen der Öffnungsstellung des Riegels ausser Eingriff kommendes und in Richtung der Schliessbewegung des Riegels nicht kraftübertragendes Kupplungselement vorgesehen ist.This object is achieved according to the invention in that the bolt forms the drive element for displacing the drive rod and is coupled to the drive rod by a displacement force deflecting the force acting in the opening direction of the bolt into a displacement force deflecting in the opening direction of the drive rod, and in that in the drive transmission an only in The direction of the opening movement of the bolt is force-transmitting coupling element which disengages when the bolt reaches the open position and is not force-transmitting in the direction of the closing movement of the bolt.

Hierdurch wird der Vorteil erzielt, dass beim Bewegen des Riegels in die Öffnungsstellung mittels eines Schlüssels automatisch auch die Treibstange und die an ihr befestigten Riegelelemente in ihre Öffnungsstellung bewegt und dort durch die beim Öffnen des Türflügels selbsttätig einrastende Arretierung arretiert werden. Andererseits ist aber, wenn der Riegel sich in Öffnungsstellung befindet, die Treibstange wieder so freigegeben, dass sie beim Schliessen des Türflügels und Ausrasten der Arretierung selbsttätig in ihre Schliessstellung zurückkehrt, ohne von dem in Öffnungsstellung befindlichen Riegel daran gehindert zu sein. Ferner stellt die in die Schliessstellung zurückgekehrte Treibstange kein Hindernis für die Verschiebung des Riegels in dessen Schliessstellung dar.This has the advantage that when the bolt is moved into the open position by means of a key, the drive rod and the bolt elements attached to it are automatically moved into their open position and are locked there by the locking mechanism that automatically locks when the door leaf is opened. On the other hand, however, when the bolt is in the open position, the drive rod is released again so that it automatically returns to its closed position when the door leaf is closed and the locking mechanism is released, without being hindered by the bolt in the open position. Furthermore, the drive rod, which has returned to the closed position, does not constitute an obstacle to the movement of the bolt in its closed position.

Für das Verständnis der Erfindung nicht erforderliche Teile sind in den Zeichnungen teilweise weggelassen bzw. nur angedeutet.Parts that are not necessary for an understanding of the invention are partially omitted from the drawings or are only hinted at.

Das in den Fig. 1 und 2 gezeigte Schlossgetriebe für den Flügel von Türen hat unter einer Stulpschiene 1, die an der Schmalseite des Türflügels befestigt ist, eine Treibstange 2, die in an sich bekannter Art und Weise Riegelelemente, z.B. 2a, trägt und durch eine bei 20 angedeutete Feder in ihre Schliessrichtung «s» gedrückt wird, und gegen diese Federkraft hin zur Schliessrichtung «s» entgegengesetzter Richtung verschiebbar ist, um die Riegelelemente 2a vom feststehenden Rahmen zu entriegeln. Im Bereich eines in den Türflügel eingesetzten Schlossgehäuses 30 mit einem zur Treibstange 2 senkrecht verschiebbaren Riegel 3 ist die Treibstange 2 unterbrochen und durch eine Verbindungsplatte 4 verbunden, auf die die Feder 20, z.B. als Druckfeder, wirkt. Unterhalb des Riegels 4 ist an der Stulpschiene 1 eine Arretiereinrichtung 5 gelagert, die zum Arretieren der Treibstangenverbindungsplatte 4 in ihrer in Fig. 2 gezeigten Öffnungsstellung dient. Sie besteht aus einer bei 21 schwenkbar gelagerten Platte 22 mit einem Vorsprung 6, der in der gegen die Schliessrichtung «s» nach oben verschobenen Stellung der Treibstange 2 unter der Kraft einer Feder 24 in eine dafür vorgesehene Aussparung 7 der Treibstangenverbindungsplatte 4 einrastet. Eine mit der Platte 22 drehfest verbundene Platte 25 an der Aussenseite der Stulpschiene 1 trägt einen Anschlagstift 8, der beim Schliessen des Flügels am feststehenden Rahmen anschlägt, wodurch die Platten 22, 25 gegen die Kraft der Feder 24 ausschwenken, der arretierende Eingriff des Vorsprungs 6 in die Ausnehmung 7 selbsttätig wieder gelöst wird, so dass die Treibstange 2 aufgrund der Kraft der Feder 20 wieder in die Schliessrichtung «s» gedrückt wird und damit die Verriegelung durch die Riegelzapfen 2a einrastet.The lock gear shown in Figs. 1 and 2 for the wing of doors has under a faceplate 1, which is attached to the narrow side of the door leaf, a drive rod 2, which carries latch elements, for example 2a, in a known manner and through a spring indicated at 20 is pressed in its closing direction "s", and can be displaced against this spring force in the opposite direction to the closing direction "s" in order to unlock the locking elements 2a from the fixed frame. In the area of a lock housing 30 inserted into the door leaf with a bolt 3 which can be displaced perpendicularly to the drive rod 2, the drive rod 2 is interrupted and connected by a connecting plate 4 on which the spring 20 acts, for example as a compression spring. Under Half of the bolt 4, a locking device 5 is mounted on the faceplate 1, which serves to lock the connecting rod connecting plate 4 in its open position shown in FIG. 2. It consists of a plate 22 which is pivotably mounted at 21 and has a projection 6 which, under the force of a spring 24, engages in a recess 7 provided in the connecting rod connecting plate 4 under the force of a spring 24 in the position of the connecting rod 2 which is displaced upward in the closing direction “s”. A plate 25 which is connected to the plate 22 in a rotationally fixed manner on the outside of the faceplate 1 carries a stop pin 8 which, when the wing closes, strikes the fixed frame, as a result of which the plates 22, 25 swing out against the force of the spring 24, the locking engagement of the projection 6 is automatically released into the recess 7 again, so that the drive rod 2 is pressed again in the closing direction “s” due to the force of the spring 20 and thus the locking engages by means of the locking pin 2a.

Der senkrecht zur Treibstange 2 verschiebbare Riegel 3 ist durch Drehen des Schlosszylinders 9 mittels eines Schlüssels zu verschieben. Dabei wird in an sich bekannter Weise die mit dem Schlüssel ausgeübte Drehkraft über ein kraft- übersetzendes Zahnradgetriebe 26 auf den Riegel 3 übertragen. Der Riegel 3 besteht aus einem äusseren Teil 10, das mit dem feststehenden Rahmen verriegelnd zusammenwirkt, und einem inneren Teil 11, das an seiner Unterseite als Zahnstange 12 ausgebildet ist und mit dem letzten Zahnrad 13 des kraftübersetzenden Getriebes 26 zusammenwirkt.The bolt 3, which can be displaced perpendicularly to the drive rod 2, can be displaced by turning the lock cylinder 9 using a key. The torque exerted with the key is transmitted to the bolt 3 in a manner known per se via a force-transmitting gear transmission 26. The bolt 3 consists of an outer part 10, which interlocks with the fixed frame, and an inner part 11, which is designed on its underside as a rack 12 and interacts with the last gear 13 of the power transmission gear 26.

Der äussere Teil 10 des Riegels 3 übergreift C-förmig das T-förmig ausgebildete Ende des inneren Teils 11, so dass das innere Teil relativ zum äusseren Teil in beiden Richtungen mit dem toten Gang, der etwa der halben Verschiebestrecke des inneren Teils entspricht, verschoben werden kann, bevor es eine Mitnahmekraft auf den äusseren Teil ausübt und diesen auf dem Rest der Verschiebestrecke in Öffnungs- oder Schliessrichtung verschiebt.The outer part 10 of the latch 3 overlaps C-shaped the T-shaped end of the inner part 11, so that the inner part is displaced relative to the outer part in both directions with the dead gear, which corresponds to approximately half the displacement distance of the inner part before it exerts a driving force on the outer part and moves it on the rest of the shift distance in the opening or closing direction.

In einer Ausnehmung innerhalb des inneren Teils 11 des Riegels ist ein Kupplungselement 14 angeordnet, das aus einer Rampe 15 mit ansteigender Arbeitsfläche 16 und einer Halteplatte 17 besteht. Die Halteplatte 17 und damit die Rampe 15 sind an der Rückwand 28 des inneren Teils 11 bei 29 schwenkbar gelagert.In a recess within the inner part 11 of the bolt, a coupling element 14 is arranged, which consists of a ramp 15 with an increasing working surface 16 and a holding plate 17. The holding plate 17 and thus the ramp 15 are pivotally mounted on the rear wall 28 of the inner part 11 at 29.

Das Kupplungselement 14 stützt sich nach unten gegen die untere Begrenzung der Ausnehmung des inneren Teils 11 des Riegels, und ausserdem gegen einen von der Rückwand 28 vorspringenden Schrägnocken 19 ab. Bei Bewegung des Teils 11 des Riegels in Fig. 1 nach rechts in die Öffnungsstellung wirkt die Arbeitsfläche 16 der Rampe 15 mit einem an der Verbindungsplatte 4 der Treibstange befestigten Nockenfolger 18 derart zusammen, dass sie diesen und damit die Verbindungsplatte 4 mit der Treibstange 2 nach oben verschiebt. Wird dagegen das innere Teil 11 des Riegels aus der Stellung nach Fig. 2 nach links in Schliessrichtung verschoben, so kann das Kupplungselement 14, wenn die Unterseite der Rampe auf den Nockenfolger 18 trifft, durch Schwenken nach oben ausweichen und den Nockenfolger überreiten.The coupling element 14 is supported downward against the lower limit of the recess of the inner part 11 of the bolt, and also against an inclined cam 19 projecting from the rear wall 28. When the part 11 of the bolt in FIG. 1 is moved to the right into the open position, the working surface 16 of the ramp 15 interacts with a cam follower 18 attached to the connecting plate 4 of the drive rod in such a way that it follows it and thus the connecting plate 4 with the drive rod 2 moves up. If, on the other hand, the inner part 11 of the bolt is moved from the position according to FIG. 2 to the left in the closing direction, the coupling element 14, when the underside of the ramp meets the cam follower 18, can deflect upwards by swiveling and pass over the cam follower.

Im folgenden wird die Funktionsweise des Beschlages anhand der Stellungen der im vorstehenden beschriebenen Teile, wie sie in den Fig. 3 bis 8 gezeigt sind, beschrieben.The functioning of the fitting is described below with reference to the positions of the parts described above, as shown in FIGS. 3 to 8.

In der, in der Fig. 3 und Fig. 1 gezeigten Schliessstellung der Treibstange 2 und bei in Schliessstellung befindlichem Riegel 3 befindet sich der Nockenfolger 18 am unteren Teil der ansteigenden Rampe 15. Wird der Riegel 3 durch Betätigung des Schliesszylinders 9 verschoben, so bewegt sich aufgrund des toten Ganges zuerst das innere Teil 11 des Riegels 3, welches mit seiner Zahnstange 12 mit dem Zahnrad 13 des Getriebes 26 im Eingriff steht. Mit der Verschiebung des inneren Teils 11 wird, wie aus der Fig. 4 ersichtlich, die Rampe 15 ebenfalls verschoben, so dass der Nockenfolger 18 an der Arbeitsfläche 16 zum Anliegen kommt und durch die schräg ansteigende Arbeitsfläche 16 angehoben wird. Da der Nockenfolger 18 starr mit der Treibstangenverbindungsplatte 4 verbunden ist, wird somit die Treibstange 2 entgegen die in Schliessrichtung «s» wirkende Federkraft angehoben. In etwa der zweiten Hälfte der Verschiebung des inneren Teils 11 nimmt dasselbe das äussere Teil 10 des Riegels 3 mit.In the closed position of the drive rod 2 shown in FIGS. 3 and 1 and when the bolt 3 is in the closed position, the cam follower 18 is located on the lower part of the rising ramp 15. If the bolt 3 is moved by actuating the locking cylinder 9, it is moved due to the dead gear, the inner part 11 of the bolt 3, which is in engagement with its rack 12 with the gear 13 of the transmission 26. With the displacement of the inner part 11, as can be seen from FIG. 4, the ramp 15 is also displaced, so that the cam follower 18 comes to rest on the working surface 16 and is raised by the obliquely rising working surface 16. Since the cam follower 18 is rigidly connected to the connecting rod connecting plate 4, the connecting rod 2 is thus raised against the spring force acting in the closing direction “s”. In approximately the second half of the displacement of the inner part 11, the same takes the outer part 10 of the bolt 3 with it.

Nachdem durch die Verschiebung des inneren und äusseren Teils 11 und 10 des Riegels 3 die in Fig. 5 gezeigte Stellung des Nockenfolgers 18 erreicht worden ist, treten die Riegelelemente 2a und der Riegel 3 aus den ihnen am feststehenden Rahmen zugeordneten Schliessblechen aus, und der Türflügel kann geöffnet werden. Dabei löst sich der Anschlagstift 8 vom feststehenden Rahmen und der Vorsprung 6 schwenkt in die Aussparung 7 ein. Nach Weiterbetätigen des Schliesszylinders 9 bis in die Endstellung, in der der Schlüssel entnommen werden kann, befindet sich der Nockenfolger 18 in der, in der Fig. 2 dargestellten Stellung am oberen Teil der Rampe 15, die Verbindungsplatte 4 der Treibstange 2 auf dem Vorsprung 6 abgesetzt und arretiert, und der Riegel 3 in seiner eingezogenen Öffnungsstellung. In der vorbeschriebenen Öffnungsstellung des Schlossgetriebes kann der Riegel 3 nicht ausgeschlossen werden, denn der Nockenfolger 18 bildet einen Anschlag für den oberen Teil der Rampe 15.After the position of the cam follower 18 shown in FIG. 5 has been reached by the displacement of the inner and outer parts 11 and 10 of the bolt 3, the bolt elements 2a and bolt 3 emerge from the striking plates assigned to them on the fixed frame, and the door leaf can be opened. The stop pin 8 is released from the fixed frame and the projection 6 pivots into the recess 7. After further actuation of the locking cylinder 9 to the end position in which the key can be removed, the cam follower 18 is in the position shown in FIG. 2 on the upper part of the ramp 15, the connecting plate 4 of the drive rod 2 on the projection 6 set down and locked, and the bolt 3 in its retracted open position. In the above-described open position of the lock gear, the bolt 3 cannot be excluded, because the cam follower 18 forms a stop for the upper part of the ramp 15.

Wird der Türflügel mit dem in dieser, in der Fig. 2 gezeigten Öffnungsstellung befindlichen Schlossgetriebe zugedrückt, so wird die Arretierung zwischen Treibstangenverbindungsplatte 4 und Platte 22 gelöst, da der Vorsprung 6 an der Platte 22 aus dem Eingriff in die Aussparung 7 ausschwenkt und die Treibstangenverbindungsplatte 4 und damit die Treibstange 2 kehren aufgrund der Wirkung der Feder 20 in die, in der Fig. 6 gezeigte Position zurück, in der die Riegelelemente 2a der Treibstange 2 verriegelt sind. Mit der Bewegung der Verbindungsplatte 4 gelangt auch der Nockenfolger 18 in die, in der Fig. 6 gezeigte Stellung links unterhalb der Rampe 15 liegend. In dieser Stellung kann der Riegel 3 in Schliessrichtung durch Betätigen des Schliesszylinders 9 verschoben werden. Dabei wird die Rampe 15, die bei 29 am inneren Teil 11 des Riegels 3 drehbar gelagert ist, wie aus Fig. 7 ersichtlich, während der Bewegung des inneren Teils 11, durch den Nockenfolger 18 etwas angehoben und gleitet über diesen hinweg. In der, in der Fig. 8 gezeigten Stellung, in der der Riegel 3 wieder versperrt ist, ist die durch eine nicht dargestellte Feder vorgespannte Rampe 15 wieder zurückgefallen, und der Nockenfolger 18 befindet sich wiederum rechts unten neben der Rampe. Während dem Gleiten der Rampe 15 über den Nockenfolger 18 wird diese Gleitbewegung nicht durch den Schrägnocken 19 behindert, sobald sich der Nokkenfolger 18 in seiner korrekten unteren Stellung gemäss Fig. 6 befindet. Sollte dies beispielsweise aufgrund einer klemmenden Feder od. dgl. nicht der Fall sein, so drückt der Schrägnocken 19 während seiner Bewegung in die Sperrichtung des Riegels 3 den Nockenfolger 18 nach unten.If the door leaf is closed with the lock gear in this open position shown in FIG. 2, the locking between the connecting rod connecting plate 4 and plate 22 is released, since the projection 6 on the plate 22 swings out of engagement with the recess 7 and the connecting rod connecting plate 4 and thus the drive rod 2 return due to the action of the spring 20 in the position shown in FIG. 6, in which the locking elements 2a of the drive rod 2 are locked. With the movement of the connecting plate 4 arrives the cam follower 18 also lies in the position shown in FIG. 6 on the left below the ramp 15. In this position, the bolt 3 can be moved in the closing direction by actuating the locking cylinder 9. The ramp 15, which is rotatably supported at 29 on the inner part 11 of the bolt 3, as can be seen in FIG. 7, is slightly raised by the cam follower 18 during the movement of the inner part 11 and slides over it. In the position shown in FIG. 8, in which the bolt 3 is locked again, the ramp 15 biased by a spring, not shown, has fallen back again, and the cam follower 18 is again located at the bottom right next to the ramp. During the sliding of the ramp 15 over the cam follower 18, this sliding movement is not impeded by the oblique cam 19 as soon as the cam follower 18 is in its correct lower position according to FIG. 6. If this should not be the case, for example, due to a clamping spring or the like, the inclined cam 19 presses the cam follower 18 downward during its movement in the locking direction of the bolt 3.

Der Türflügel kann durch Betätigen einer beispielsweise innen mit einer Nuss 33 verbundenen Klinke geöffnet werden, sofern dazu der Riegel 3 zuvor in die in Fig. 6 gezeigte Öffnungsstellung gebracht worden ist. Dazu ist auf der Nuss 33 ein hebelförmiges weiteres Antriebsglied 32 einerends gelagert. Das andere Ende des Antriebsgliedes 32 steht in 31 mit der Verbindungsplatte 4, und somit mit der Treibstange 2 in Eingriff. Die Lagerung des Antriebsgliedes 32 auf der Nuss 33 ist begrenzt und erlaubt nur einen Leergang des Antriebsgliedes 32 im Verhältnis zur Nuss 33, der dem Hub der Treibstange 2 entspricht. Dieser Leergang ist so angeordnet, dass die Treibstange 2 aus der Öffnungsstellung in die Schliessstellung gleiten kann, ohne über das Antriebsglied 32 auf die Nuss 33 und somit auf die Klinke einzuwirken, danach jedoch ohne Leergang von der Klinke und der Nuss 33 über das Antriebsglied 32 wieder in die Öffnungsstellung gebracht werden kann.The door leaf can be opened by actuating, for example, a latch connected internally to a nut 33, provided that the latch 3 has previously been brought into the open position shown in FIG. 6. For this purpose, a lever-shaped further drive member 32 is mounted on one end on the nut 33. The other end of the drive member 32 is in 31 with the connecting plate 4, and thus with the drive rod 2 in engagement. The mounting of the drive member 32 on the nut 33 is limited and only allows the drive member 32 to run empty in relation to the nut 33, which corresponds to the stroke of the drive rod 2. This empty gear is arranged in such a way that the drive rod 2 can slide from the open position into the closed position without acting on the nut 33 and thus on the pawl via the drive member 32, but thereafter without idle gear on the pawl and the nut 33 via the drive member 32 can be brought back into the open position.

Durch den toten Gang zwischen innerem und äusserem Teil 11 und 10 des Riegels 3 ist es vorteilhafterweise möglich, bei einem vorbestimmten Riegelausschluss den Hub der Rampe 15 zu vergrössern und somit eine funktionserleichternde geringere Steigung der Rampe 15 zu ermöglichen. Auch wird dadurch das zur Entkupplung des Riegels 3 von der Treibstange 2 benötigte Entfernen des Nockenfolgers 18 von dem oberen Ende der Rampe 15 erleichtert. Des weiteren wird die Breite des Schlossgehäuses und somit dessen Einbautiefe in normalen Grenzen gehalten.Due to the dead aisle between the inner and outer parts 11 and 10 of the latch 3, it is advantageously possible to increase the stroke of the ramp 15 with a predetermined latch exclusion and thus to enable a functionally easier, lower slope of the ramp 15. This also makes it easier to remove the cam follower 18 from the upper end of the ramp 15 to decouple the bolt 3 from the drive rod 2. Furthermore, the width of the lock housing and thus its installation depth is kept within normal limits.

Zweckmässigerweise ist die Rampe 15 an ihrer Arbeitsfläche 16 mit Stufen versehen, auf denen der Nockenfolger 18 verweilen kann, während beim Aufschliessen die Schliessumdrehung des Schlüssels, beispielsweise zum Umgreifen, unterbrochen wird. Man kann also auch während des Aufschliessens den Schlüssel loslassen, ohne dass die Feder 20 die Verbindungsplatte 4 mit dem Nockenfolger 18 wieder nach unten bewegt und ohne dass der Nockenfolger 18 über die Rampe 15 eine Rückstellkraft auf den Riegel 3 ausübt.The ramp 15 is expediently provided on its working surface 16 with steps on which the cam follower 18 can linger, while the unlocking rotation of the key is interrupted, for example for reaching around, when unlocking. You can also release the key during unlocking without the spring 20 moving the connecting plate 4 with the cam follower 18 downwards again and without the cam follower 18 exerting a restoring force on the bolt 3 via the ramp 15.

Claims (6)

1. A lock mechanism for the leaf of a door, with at least one connecting rod (2) which carries at least one bolt element (2a) and which is arranged to be displaceable parallel to the faceplate (1) of the lock mechanism and which is urged into a closed position by spring force, with a drive member acting on the connecting rod (2) so as to displace the connecting rod against the spring force into an open position, with arresting means (5) cooperating with the connecting rod (2), which automatically engage in the open position of the connecting rod and retain the latter in the open position and which, when the door leaf is closed, are caused to be disengaged by the door-locating frame, and with a bolt (3) which can be moved transversely to the connecting rod (2) by means of a key, characterised in that the bolt (3) constitutes the drive member for displacing the connecting rod (2) and is coupled to the connecting rod (2) by a drive transmission (15,18) which converts the displacing force acting in the opening direction of the bolt into a displacing force acting in the opening direction of the connecting rod, and in that in the drive transmission there is provided a coupling element (14) which transmits force only in the direction of the opening movement of the bolt (3), which is disengaged upon reaching the open position of the bolt (3) and which does not transmit force in the direction of the closing movement of the bolt.
