Description

Die Erfindung betrifft ein Mehrriegelschloß mit Falle, Riegel, mindestens einer Schubstange mit Anschlußschieber und mit einem Innen- und einem Außendrücker, die in einer axial geteilten Nuß oder in versetzt zueinander angeordneten, separaten Nussen formschlüssig gehalten und zum Verriegeln aus einer neutralen, insbesondere horizontalen Mittelstellung hochschwenkbar und zum Öffnen aus der Mittelstellung herunterdrückbar sind.The invention relates to a multi-bolt lock with latch, bolt, at least one push rod with connecting slide and with an inner and an outer handle, which is held in a form-fitting manner in an axially divided nut or in offset separate nuts, and for locking from a neutral, in particular horizontal, central position can be swiveled up and pushed down to open from the middle position.

Bei Mehrriegelschlössern, also Anordnungen, bei welchen über den Schloßkasten hinausgehende Schubstangen weitere Riegel, z. B. im Stulp einer Tür,betätigt werden, erfolgt die Kraftübertragung an die Schubstangen entweder mittels eines Schlüssels über einen Schließzylinder und ein Zahnradgetriebe oder mittels der Drücker, die über den normalen Betätigungsbereich hinaus eine weitere Stellung (Verriegelungsstellung) einnehmen können.For multi-bolt locks, i.e. arrangements in which push rods extending beyond the lock case, additional bolts, e.g. B. operated in the faceplate of a door, the power is transmitted to the push rods either by means of a key via a lock cylinder and a gear transmission or by means of the handle, which can assume a further position (locking position) beyond the normal operating range.

Aus der EP-A1 454 966 ist ein schließzylinderbetätigbares Treibstangenschloß bekannt, das einen den Schließbart des Schließzylinders umfassenden, im Schloßgehäuse angeordneten Zahnkranz mit Durchsteckspalt für den Schließbart besitzt. Die Drehung des Zahnkranzes wird mittels eines Untersetzungsgetriebes in eine lineare Schiebebewegung umgewandelt.From EP-A1 454 966 a lock cylinder-actuable espagnolette lock is known which has a toothed ring which comprises the lock bit of the lock cylinder and is arranged in the lock housing and has a slot for the lock bit. The rotation of the ring gear is converted into a linear sliding movement by means of a reduction gear.

In der EP-A2 391 063 ist ein Treibstangenschloß beschrieben, dessen Treibstangen durch Verdrehen des Drückers gesteuert werden. Eine Drückernuß wird durch Federkraft in der Grundstellung bzw. Mittelstellung gehalten, aus der der Drücker in einander entgegengesetzte Richtungen schwenkbar ist. Der Nuß ist ein Betätigungsarm zugeorndet, welcher bei Verdrehen der Nuß die Treibstangen in der über den Drücker bestimmten Richtung mitschleppt.EP-A2 391 063 describes a connecting rod lock, the connecting rods of which are controlled by turning the handle. A follower is held by spring force in the basic position or middle position, from which the lever can be pivoted in opposite directions. The nut is assigned an actuating arm which, when the nut is turned, entrains the drive rods in the direction determined by the handle.

Insbesondere dann, wenn ein Schloß neben einer Fallen- und Riegelbetätigung, einem Sperrsystem mit Schließzylinder und zwei ausschiebbaren Schubstangen noch weitere Funktionen wie etwa jene einer Notöffnung von der Innenseite erfüllen soll, müssen Gesamtabmessungen in Kauf genommen werden, die jene eines genormten Einsteckschlosses bei weitem überschreiten. Dornmaße und Anschlußmaße können konstruktionsbedingt nicht eingehalten werden. Die Erfindung zielt darauf ab, ein Mehrriegelschloß zu schaffen, das kompakt aufgebaut ist, Normabmessungen aufweisen kann und das neben einer Fallen- und Riegelfunktion versperrbar ist und mit einer zuverlässigen Notöffnungsmöglichkeit ausgestattet sein kann.In particular, if a lock is to perform other functions such as that of an emergency opening from the inside in addition to a latch and bolt actuation, a locking system with a locking cylinder and two extendable push rods, overall dimensions must be accepted that far exceed those of a standard mortise lock . Backset and connecting dimensions cannot be maintained due to the design. The invention aims to provide a multi-bolt lock to create, which is compact, can have standard dimensions and which can be locked in addition to a latch and bolt function and can be equipped with a reliable emergency opening.

Dies wird erfindungsgemäß dadurch erreicht, daß die Nuß des Innendrückers über ein Hebelgetriebe mit mindestens einer Schubstange bzw. deren Anschlußschiebern in kinematischer Verbindung steht und die Nuß des Innendrückers vorzugsweise einen mit der Nuß verbundenen Hebel aufweist, dessen freies Ende gegen Mitnehmeranschläge auf einer der Schubstangen bzw. auf deren Anschlußschieber schwenkbar ist, daß die Nuß des Außendrückers an der Antriebsseite eines Zahnradgetriebes liegt, dessen Zahnräder mit verzahnten Bereichen beider Schubstangen bzw. Anschlußschieber kämmen und daß zwischen der Nuß des Innendrückers sowie des Außendrückers und den Schubstangen bzw. den Anschlußschiebern ein Freigang zur leeren Rückstellung des Innen- sowie des Außendrückers in die Mittelstellung vorgesehen ist. Dieser Aufbau erlaubt geringe Abmessungen, weil sich die Konstruktionselemente gegenseitig nicht behindern und ermöglicht ein leeres Zurückdrehen der Drücker aus der Sperrstellung in die neutrale Grund- oder Mittelstellung. Es ist zweckmäßig, wenn die Mitnehmeranschläge der Schubstange bzw. deren Anschlußschieber einen Abstand voneinander aufweisen und das freie Ende des Hebels zwischen den Mitnehmeranschlägen liegt und wenn die Nuß des Außendrückers einen radialen Mitnehmer trägt, der zwischen Anschläge eines Zahnrades bzw. Zahnradsegmentes des Zahnradgetriebes eingreift, wobei der Abstand der Mitnehmeranschläge der Schubstange bzw. des Anschlußschiebers sowie der Anschläge des Zahnrades bzw. Zahnradsegmentes mindestens dem Drehwinkel der Drücker aus der Mittelstellung in die Sperrstellung bzw. aus der Mittelstellung in die Offenstellung entspricht. Der Abstand ist auf den Drückerwinkel abgestimmt.This is achieved according to the invention in that the nut of the inner handle is in a kinematic connection via a lever mechanism with at least one push rod or its connecting slides and the nut of the inner handle preferably has a lever connected to the nut, the free end of which against driver stops on one of the push rods or . on the connecting slide is pivotable that the nut of the outer handle is located on the drive side of a gear transmission, the gears mesh with toothed areas of both push rods or connecting slide and that between the nut of the inner handle and the outer handle and the push rods or the connecting slide there is free access to empty return of the inside and outside handle is provided in the middle position. This construction allows small dimensions because the construction elements do not interfere with each other and enables the handles to be turned back from the locked position into the neutral basic or middle position. It is expedient if the driver stops of the push rod or their connecting slide are spaced apart from one another and the free end of the lever lies between the driver stops and if the nut of the outer lever carries a radial driver which engages between stops of a gear wheel or gear segment of the gear transmission, wherein the distance between the driver stops of the push rod or the connecting slide and the stops of the gear or gear segment corresponds at least to the angle of rotation of the handle from the central position to the locked position or from the central position to the open position. The distance is matched to the handle angle.

Eine Ausführung eines Mehrriegelschlosses mit Falle, Riegel, einem Schließzylinder, mindestens einer Schubstange mit Anschlagschieber und einem Innen- und einem Außendrücker, die in einer axial geteilten Nuß oder in versetzt zueinander angeordneten, separaten Nussen formschlüssig gehalten und zum Verriegeln aus einer neutralen, insbesondere horizontalen Mittelstellung hochschwenkbar und zum Öffnen aus der Mittelstellung herunterdrückbar sind ist dadurch gekennzeichnet, daß der Riegel durch eine Zapfen-Schlitzsteuerung mit einem schräg zur Ausschubrichtung des Riegels liegenden Schlitz, insbesondere im Riegelschaft und dem Zapfen auf einer der Schubstangen bzw. deren Anschlußschieber bei Betätigung der Schubstangen ein- und ausschiebbar ist und daß mit dem Schließzylinder eine Sperrnase einer Sperrplatte zur Lagefixierung der Schubstangen bzw. der Anschlußschieber und Blockierung der Drückerbetätigung in eine Ausnehmung bzw. über einen Vorsprung einer der Schubstangen bzw. deren Anschlußschieber schiebbar ist. Es wird somit der Riegel nicht über den Schließzylinder betätigt, wie dies bei den üblichen Schlössern der Fall ist, sondern durch eine der Schubstangen. Durch den Schließzylinder, der die Sperrplatte verschiebt, erfolgt die Blockierung des Systems in einfacher Weise und mit geringem konstruktiven Aufwand, sodaß ein Betätigen über den Außendrücker oder durch Zurückdrücken des oder der Riegel nicht möglich ist. Diese Blockierung kann zusammen mit jeder beliebigen Schubstangen-Betätigungsmechanik verwendet werden, eignet sich aber für die oben genannte Kinematik besonders gut. Es ist zweckmäßig, wenn die Sperrplatte Mitnehmeranschläge, insbesondere eine seitliche Ausnehmung mit Steuerkanten, zum Eingriff der Zylindernocke des Schließzylinders bei Verriegeln oder Entriegeln durch den Schließzylinder aufweist und wenn eine gegen den Schließzylinder bewegbare, vorgespannte Feder bzw. eine Federplatte vorgesehen ist, deren Stirnfläche den Drehkreis der Zylindernocke im Bereich der Steuerkante sehnenartig durchsetzt und die Zylindernocke aus dem Bereich der Steuerkanten der Ausnehmung etwa bei unzureichender Schlüsseldrehung, mit Federkraft herausdreht. Dadurch wird verhindert, daß beim Steckenlassen des Schlüssels die Zylindernocke in einer Stellung verbleibt, in der die Zylindernocke die Bewegung der Sperrplatte blockert, also eine Totpunktlage einnimmt. Der Schlüssel kann in einer Zwischenstellung nicht abgezogen werden und überdies verhindert die genannte Totpunktlage ein Notöffnen des Mehrriegelschlosses. Letzteres wird dadurch erreicht, daß zur Notöffnung bzw. Panikentriegelung mittels des Innendrückers dessen Nuß einen linearen Schieber, bespielsweise mittels eines radialen Fingers steuert, der in eine seitliche Ausnehmung bzw. Zahnlücke des Schiebers eingreift und wobei der Schieber stirnseitig eine schräge Steuerfläche aufweist, welche bei gesperrtem Riegel gegen einen Anschlag bzw. eine Mitnehmerfläche der Sperrplatte zum Zurückziehen der Sperrnase aus der Ausnehmung bzw. von dem Vorsprung der Schubstange oder deren Anschlußschieber schiebbar ist. Dieser lineare Schieber entspricht einem Keil, der senkrecht auf einen Anschlag der Sperrplatte einwirkt und dadurch zur Notöffnung diese zurückzieht. Der Vorgang wird von dem Innendrücker zu Beginn des Niederdrückers ausgelöst, wobei der anschließende Drückerweg der nun freigegebenen Verschiebung der Schubstangen dient. In dieser Hinsicht ist in zweckmäßiger Weise vorgesehen, daß zwischen dem freien Ende des Hebels des Hebelgetriebes der Nuß des Innendrückers in der Position der Drücker-Mittelstellung und dem Mitnehmeranschlag zum Entriegeln an der Schubstange oder an ihrem Anschlußschieber in der Verriegelungsstellung der Schubstange, ein Abstand vorgesehen ist, der mindestens jenem Drehwinkel des Hebels entspricht, gemäß welchem die Sperrnase der Sperrplatte um die Eingriffstiefe in die Ausnehmung bzw. das Maß des Übergreifens des Vorsprunges der Schubstange bzw. des Anschlußschiebers zurückgezogen ist. Für die Rückführung der Drücker in die Grund- bzw. Mittelstellung ist es zweckmäig, wenn die Nuß des Innendrückers an einem Teil ihres Umfanges eine Verzahnung aufweist, die mit einer Zahnstange kämmt, welche aus einer stabilen Mittellage gegen Federkraft im Ausmaß des Drückerwinkels linear nach oben und nach unten verschiebbar ist.An embodiment of a multi-bolt lock with latch, bolt, a lock cylinder, at least one push rod with stop slide and an inner and an outer handle, which is held in a form-fitting manner in an axially divided nut or in offset separate nuts and for Locking can be swiveled up from a neutral, in particular horizontal, central position and pressed down to open it from the central position, characterized in that the bolt is controlled by a pin slot control with a slot lying obliquely to the direction in which the bolt is pushed out, in particular in the bolt shaft and the pin on one of the push rods or whose connecting slide can be pushed in and pushed out when the push rods are actuated, and that a locking lug of a locking plate for fixing the position of the push rods or the connecting slide and blocking the trigger actuation into a recess or over a projection of one of the push rods or its connecting slide can be pushed with the locking cylinder . The bolt is therefore not actuated via the lock cylinder, as is the case with the usual locks, but by one of the push rods. The locking cylinder, which moves the locking plate, blocks the system in a simple manner and with little design effort, so that actuation via the outside handle or by pushing back the bolt or bolts is not possible. This blocking can be used together with any push rod actuation mechanism, but is particularly suitable for the above-mentioned kinematics. It is expedient if the locking plate has driver stops, in particular a lateral recess with control edges, for engaging the cylinder cam of the locking cylinder when locking or unlocking by the locking cylinder, and if a preloaded spring or a spring plate that can be moved against the locking cylinder is provided, the end face of which Rotating circle of the cylinder cam in the area of the control edge is penetrated like a string and the cylinder cam is unscrewed from the area of the control edges of the recess, for example in the event of insufficient key rotation, with spring force. This prevents the cylinder cam from remaining in a position in which the cylinder cam blocks the movement of the locking plate, ie assumes a dead center position, when the key is left in place. The key cannot be removed in an intermediate position and, moreover, the dead center position prevents an emergency opening of the multi-bolt lock. The latter is achieved that for emergency opening or panic unlocking by means of the inside handle, the nut controls a linear slide, for example by means of a radial finger, which engages in a lateral recess or tooth space of the slide and the slide has an oblique control surface on the end face, which, when the bolt is locked, prevents a stop or a driver surface of the locking plate for withdrawing the locking lug from the recess or from the projection of the push rod or the connecting slide is slidable. This linear slide corresponds to a wedge that acts perpendicularly on a stop of the locking plate and thereby pulls it back to the emergency opening. The process is triggered by the inside pusher at the beginning of the pusher, with the subsequent pusher path serving the now released displacement of the push rods. In this regard, it is expediently provided that a distance is provided between the free end of the lever of the lever mechanism, the nut of the inside handle in the position of the handle center position and the driver stop for unlocking on the push rod or on its connecting slide in the locking position of the push rod is, which corresponds to at least that angle of rotation of the lever, according to which the locking lug of the locking plate is retracted by the engagement depth into the recess or the degree of overlap of the projection of the push rod or the connecting slide. For returning the handle to the basic or middle position, it is expedient if the nut of the inner handle has a toothing on part of its circumference that meshes with a toothed rack that linearly upwards from a stable center position against spring force to the extent of the handle angle and is slidable down.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in den Zeichungen dargestellt. Fig. 1 zeigt ein Mehrriegelschloß bei offener Tür bei abgenommener Schloßdecke, Fig. 2 das Schloß bei geschlossener Tür und am Ende der Aufwärtsbewegung des Inndendrückers zum Versperren der Riegel, Fig. 3a das Schloß bei geschlossener Tür, Riegeln in der Sperrstellung und Blockierung durch Schließzylinderbetätigung und Fig. 3b ein Detail aus Fig. 3a in einer Zwischenstellung des Schlüssels im Schließzylinder. Zur Vereinfachung der Darstellung und besseren Übersichtlichkeit wurden die übereinanderliegenden Schieber, Hebel und Platten jeweils mit vollen Linien gezeichnet.An embodiment of the subject of the invention is shown in the drawings. Fig. 1 shows a multi-bolt lock when the door is open with the lock cover removed, Fig. 2 shows the lock when the door is closed and at the end of the upward movement of the inside handle to lock the bolts, Fig. 3a shows the lock when the door is closed, locks in the locked position and blocking by locking cylinder actuation and FIG. 3b shows a detail from FIG. 3a in an intermediate position of the key in the locking cylinder. In order to simplify the presentation and improve clarity, the slides, levers and plates one above the other were drawn with full lines.

In einem Schloßkasten 1 (Fig. 1) sind eine Nuß 2 für einen Innendrücker und eine Nuß 3 für einen Außendrücker vorgesehen. Zur besseren Übersichtlichkeit sind diese Nussen 2, 3 mit versetzten Achsen dargestellt. Es kann aber auch eine geteilte Nuß zum Einsatz kommen, bei welcher auf einer gemeinsamen geometrischen Achse zwei unabhängig voneinander betätigbare Nussen sitzen. Die Nuß 2 trägt einen Hebel 4, der zwischen zwei Anschläge 5, 6 auf einem Anschlußschieber 7 der unteren Schubstange 8 greift. Wird die Nuß 2 durch Hochschwenken des Innendrückers gegen den Uhrzeiger um z. B. 45° gedreht, dann drückt der Hebel 4 auf den Anschlag 5 und der Anschlußschieber 7 sowie die Schubstange 8 werden nach unten geschoben (Fig. 2).In a lock case 1 (Fig. 1), a nut 2 for an inside handle and a nut 3 for an outside handle are provided. For better clarity, these nuts 2, 3 are shown with offset axes. However, a split nut can also be used, in which two nuts which can be actuated independently of one another are seated on a common geometric axis. The nut 2 carries a lever 4 which engages between two stops 5, 6 on a connecting slide 7 of the lower push rod 8. If the nut 2 by swiveling the inner handle counterclockwise by z. B. rotated 45 °, then the lever 4 presses on the stop 5 and the connecting slide 7 and the push rod 8 are pushed down (Fig. 2).

Die Nuß 2 verfügt ferner über eine Nase 9, die beim Niederdrücken des Inndendrückers - also einer Drehung der Nuß 2 im Uhrzeigersinn - einen Gleitstein 10 des Fallenschaftes 11 der Falle 12 gegen die Kraft einer Feder 13 zurückzieht. Bei offener Tür, wie dies in Fig. 1 dargestellt ist, tritt die Falle 12 weiter über die Stulpschiene 14 hinaus als bei geschlossener Tür, wenn sie am stockseitigen Schließblech, z. B. am Boden der Fallenausnehmung des Schließbleches anliegt. Dadurch hintergreift bei offener Tür (Fig. 1) der Gleitstein 10 eine Hinterschneidung 15 des Anschlußschiebers 7 und blockiert somit die Schubstange 8 aber auch die Schubstange 31, deren Anschlußschieber 30 mit dem Anschlußschieber 7 durch ein Zahnradgetriebe 18, 19, 20,21 kinematisch verbunden ist.The nut 2 also has a nose 9, which pulls back a sliding block 10 of the falling shank 11 of the case 12 against the force of a spring 13 when the inside handle is depressed - that is, a rotation of the nut 2 clockwise. With the door open, as shown in Fig. 1, the case 12 occurs further beyond the faceplate 14 than when the door is closed when it on the stock-side striking plate, z. B. abuts the bottom of the latch recess of the striking plate. As a result, the sliding block 10 engages behind an undercut 15 of the connecting slide 7 when the door is open (FIG. 1) and thus blocks the push rod 8 but also the push rod 31, the connecting slide 30 of which is kinematically connected to the connecting slide 7 by a gear transmission 18, 19, 20, 21 is.

Die Nuß 2 verfügt ferner über eine Verzahnung 22, die in eine längsgeführte, tangential zur Verzahnung 22 angeordnete Zahnstange 23 eingreift. Durch die Kraft einer oder mehrer Federn 24 wird die Zahnstange 23 in der dargestellten Mittelstellung gehalten. Auf diese Weise wirkt die Feder 24 als Drückerfeder, stellt aber auch den Drücker der Nuß 2 nach seinem Hochschwenken in die horizontale Mittellage zurück. Bei dem letztgenannten Vorgang schwenkt der Hebel 4 der Nuß 2 leer in die Position gemäß Fig. 3a zurück. Die Schubstangen verbleiben in der Sperrposition.The nut 2 also has a toothing 22 which engages in a longitudinally guided rack 23 arranged tangentially to the toothing 22. The toothed rack 23 is held in the central position shown by the force of one or more springs 24. In this way, the spring 24 acts as a pusher spring, but also resets the pusher of the nut 2 after it swings up into the horizontal central position. In the latter process, the lever 4 of the nut 2 swings back empty into the position shown in FIG. 3a. The push rods remain in the locked position.

Mit der Nuß 3 ist ein Mitnehmer 25 verbunden, der mit zwei im Winkel zueinander vesetzten Anschlägen 26, 27 zusammenarbeitet, welche sich auf einem konzentrisch die Nuß 3 umgebenden Lagerring 28 befinden. Der Lagerring 28 trägt ein Zahnradsegment 29, dessen Verzahnung mit dem Zahnrad 18 kämmt. Das starr mit diesem verbundene Zahnrad 19 greift in die Verzahnung des Anschlußschiebers 7 der nach unten gerichteten Schubstange 8 ein. Das letztgenannte Zahnrad 19 kämmt mit dem Zahnrad 20, mit dem das Zahnrad 21 starr verbunden ist. Dieses Zahnrad 21 greift in eine Verzahnung eines Anschlußschiebers 30 der nach oben gerichteten Schubstange 31.With the nut 3, a driver 25 is connected, which cooperates with two mutually offset stops 26, 27, which are located on a concentrically surrounding the nut 3 bearing ring 28. The bearing ring 28 carries a gear segment 29, the teeth of which mesh with the gear 18. The rigidly connected to this gear 19 engages in the toothing of the connecting slide 7 of the downward push rod 8. The latter gear 19 meshes with the gear 20 to which the gear 21 is rigidly connected. This gearwheel 21 engages in a toothing of a connecting slide 30 of the upwardly directed push rod 31.

Wenn der Drücker (Außendrücker) der Nuß 3 um etwa 45° nach oben geschwenkt wird, also sich die Nuß 3 um 45° im Gegenuhrzeigersinn verdreht, dann schwenkt das Zahnradsegment 29 nach unten, sodaß sich die Zahnräder 18, 19 im Uhrzeigersinn und die Zahnräder 20, 21 im Gegenuhrzeigersinn drehen. Somit erfolgt ein Verschieben der Schubstangen 8, 31 in divergierende Richtungen in die Sperrstellung. Der Außendrücker wird mittels seiner hier nicht dargestellten Drückerfeder in die horizontale Mittellage leer zurückgedreht. Diese Endposition ist in Fig. 3 dargestellt.If the pusher (external handle) of the nut 3 is pivoted upwards by approximately 45 °, i.e. the nut 3 rotates counterclockwise by 45 °, then the gear segment 29 pivots downward, so that the gear wheels 18, 19 turn clockwise and the gear wheels 20, 21 turn counterclockwise. Thus, the push rods 8, 31 are moved in diverging directions into the locked position. The outside handle is turned back empty into the horizontal central position by means of its pressing spring, not shown here. This end position is shown in Fig. 3.

Mit der Nuß 2 ist ein Lenker 32 verbunden, dessen stirnseitiger Anschlag gemäß Fig. 1 an dem Mitnehmer 25 der Nuß 3 anliegt. Dadurch bewirkt ein Niederdrücken des Außendrückers (Drehung der Nuß 3 im Uhrzeigersinn) ein Anheben des Lenkers 32 und damit ein Verdrehen der Nase 9 im Uhrzeigersinn, sodaß die Falle 12 über den Schaft 11 und dem Gleitstein 10 gegen die Kraft der Feder 13 zurückgezogen wird.A handlebar 32 is connected to the nut 2, the end stop of which, according to FIG. 1, bears against the driver 25 of the nut 3. Depressing the outside handle (rotation of the nut 3 clockwise) causes the handlebars 32 to be raised and thus the nose 9 to be rotated clockwise, so that the latch 12 is retracted against the force of the spring 13 via the shaft 11 and the sliding block 10.

Im Schloßkasten 1 ist ferner ein Riegel 33 vorgesehen, dessen Riegelschaft 34 einen schräg zur Ausschubrichtung verlaufenden Schlitz 35 aufweist, in den ein Zapfen 36 des Anschlußschiebers 7 eingreift. Bewegt sich beim Hochdrehen eines Drückers zum Zwecke der Verriegelung der Anschlußschieber 7 nach unten, dann schiebt der Zapfen 36 den Riegel 33 nach außen in die in Fig. 2 dargestellte Sperrstellung. Der schrägliegende Schlitz 35 geht an seinem unteren Ende in einen vertikalen Endteil über, der also senkrecht zur Ausschubrichtung des Riegels liegt. Wenn der Zapfen 35 diese Position (Fig. 2) einnimmt, dann kann der Riegel 33 von außen (etwa mit einem Schraubendreher) nicht mehr zurückgeschoben werden. Um darüber hinaus aber auch ein Öffnen durch Drückerbetätigung zu verhindern, ist ein Schließzylinder 37 vorgesehen, dessen Schließnocke 38 beim Sperren in eine Ausnehmung 39 einer verschiebbar gelagerten Sperrplatte 40 greift und sich gegen eine Steuerkante 41 legt, um die Sperrplatte 40 nach links zu verschieben. Die Sperrplatte 40 trägt eine Sperrnase 42. Im schlußschieber 7 ist eine Ausnehmung 43 vorgesehen, die gemäß Fig. 2 der Sperrnase 42 der Sperrplatte 40 gegenüberliegt. In Fig. 3 ist die Situation nach Beendigung des Sperrens mittels des Schließzylinders 37 dargestellt. Die Schließnocke 38 hat die Sperrplatte 40 bzw. deren Sperrnase 42 so weit nach links verschoben, daß die Sperrnase 42 in die Ausnehmung 43 greift. Die Sperrstellung der Schubstangen 8, 31 in welcher sich diese gemäß Fig. 3a befinden, wird so über den Schließzylinder 37 verriegelt.A lock 33 is also provided in the lock case 1, the lock shaft 34 of which has a slot 35 which extends obliquely to the extension direction and into which a pin 36 of the connecting slide 7 engages. Moves down when turning a handle for the purpose of locking the connecting slide 7, then the pin 36 pushes the bolt 33 outwards into the locking position shown in FIG. 2. The slanting slot 35 merges at its lower end into a vertical end part, which is therefore perpendicular to the direction of extension of the bolt. When the pin 35 is in this position (Fig. 2) takes, then the bolt 33 can no longer be pushed back from the outside (for example with a screwdriver). In order to prevent opening by push button actuation, a locking cylinder 37 is provided, the locking cam 38 of which engages in a recess 39 of a displaceably mounted locking plate 40 when it is locked and lies against a control edge 41 in order to shift the locking plate 40 to the left. The locking plate 40 carries a locking lug 42. In the closing slide 7, a recess 43 is provided which, according to FIG. 2, is opposite the locking lug 42 of the locking plate 40. 3 shows the situation after the locking has ended by means of the locking cylinder 37. The locking cam 38 has moved the locking plate 40 or its locking lug 42 to the left so far that the locking lug 42 engages in the recess 43. The locking position of the push rods 8, 31 in which they are located according to FIG. 3a is locked via the locking cylinder 37.

Eine weitere Ausnehmung (nicht dargestellt) kann in der Position des Anschlußschiebers 7 nach Fig. 1 der Sperrnase 42 gegenüberliegen. Wird diese Position mittels des Schließzylinders 37 fixiert, dann kann das Schloß nicht verriegelt werden; es bleibt zwangsläufig offen.Another recess (not shown) can be opposite the locking lug 42 in the position of the connecting slide 7 according to FIG. 1. If this position is fixed by means of the lock cylinder 37, the lock cannot be locked; it inevitably remains open.

In der Verriegelungsstellung nach Fig. 3, die durch den Sperrschieber 40 fixiert ist, besteht die Möglichkeit der Notöffnung von der Innenseite, also mittels des Innendrückers - ohne Schlüssel. Dazu ist im Schloßgehäuse 1 ein Schieber 44 vorgesehen, der senkrecht geführt ist und der eine Zahnlücke 45 aufweist, in die ein radialer Finger 46 der Nuß 2 eingreift. Der Schieber 44 trägt stirnseitig, der Sperrplatte 40 zugewandt, eine schräge Steuerfläche 47, die an einer Anschlagfläche 48 der Sperrplatte 40 anliegt.3, which is fixed by the locking slide 40, there is the possibility of emergency opening from the inside, ie by means of the inside handle - without a key. For this purpose, a slide 44 is provided in the lock housing 1, which is guided vertically and has a tooth space 45, in which a radial finger 46 of the nut 2 engages. At the end, the slider 44, facing the locking plate 40, carries an oblique control surface 47 which bears against a stop surface 48 of the locking plate 40.

Wenn nun der Innendrücker (z. B. bei einer Not- oder Paniksituation) niedergedrückt wird, dann bewegt sich der Schieber 44 gegen die Anschlagfläche 48. Die Schräge der Steuerfläche 47 ist so gerichtet, daß die Sperrplatte 40 dabei nach rechts geschoben wird. Dadurch wird die Sperrnase 42 aus der Ausnehmung nehmung 43 zurückgezogen. Sobald die Sperrnase 42 aus der 43 heranstaucht, stößt der Hebel 4 der Nuß 2 gegen den Anschlag 6 des Anschlußschiebers 7 (Fig. 2), der nun nicht mehr versperrt ist. Bei fortgesetztem Niederdrücken des Innendrückers verschiebt der Hebel 4 den Anschlußscheiber 7 und die Schubstange 8 sowie über das Zahnradgetriebe 18, 19 und 20, 21 den Anschlußschieber 30 und die Schubstange 31 in die Offenstellung.If the inside handle is now depressed (eg in an emergency or panic situation), the slide 44 moves against the stop surface 48. The slope of the control surface 47 is directed so that the locking plate 40 is pushed to the right. As a result, the locking lug 42 is withdrawn from the recess 43. As soon as the locking lug 42 comes up from the 43, the lever 4 pushes the nut 2 against the Stop 6 of the connecting slide 7 (Fig. 2), which is now no longer blocked. With continued depression of the inside handle, the lever 4 moves the connecting disk 7 and the push rod 8 and via the gear mechanism 18, 19 and 20, 21 the connecting slide 30 and the push rod 31 into the open position.

Es bedarf keiner näheren Erläuterung, daß an den Schubstangen 8, 31 auf Schrägflächen oder Steuerkanten auflaufende Schwenkriegel vorgesehen sein können, die beim Ausschieben der Schubstangen über den Stulp hinaus ausschwenken. Es können Zahnstangen-Zahnradgetriebe vorgesehen sein, die im eigenen Getriebegehäuse jeweils einen Riegel ausschieben. Schließlich können auf den Schubstangen in den Falz der Tür hineinragende Zapfen angeordnet sein, die in stockseitige Nuten eingreifen und beim Verschieben der Schubstangen einen Steg der Nuten hintergreifen.There is no need for any further explanation that pivot bars which run on inclined surfaces or control edges can be provided on the push rods 8, 31 and pivot out beyond the faceplate when the push rods are pushed out. Rack and pinion gearboxes can be provided, each of which pushes out a bolt in its own gearbox housing. Finally, pins projecting into the rebate of the door can be arranged on the push rods, which engage in grooves on the stock side and engage behind a web of the grooves when the push rods are moved.

Ein gefederter Raststift 49 greift in eine Ausnehmung 50 der Sperrplatte 40 um diese in der zurückgezogenen Stellung zu halten. Der Raststift 49 liegt nach dem Sperren an einer Schrägfläche 51 an (Fig. 3a) und spannt so die Sperrplatte 40 gegen die Ausnehmung 43 vor. Dadurch werden definierte Lagen erreicht, die während des Sperrvorganges mittels des Schließzylinders 37 bei der Schlüsseldrehung merkbar sind.A spring-loaded locking pin 49 engages in a recess 50 of the locking plate 40 in order to hold it in the retracted position. After locking, the locking pin 49 rests against an inclined surface 51 (FIG. 3a) and thus prestresses the locking plate 40 against the recess 43. Defined positions are thereby achieved, which are noticeable during the locking process by means of the locking cylinder 37 when the key is turned.

In der Ausnehmung 39 der Sperrplatte 40 liegt eine Federplatte 52, die durch Federkraft gegen den Schließzylinder vorgespannt ist. Beim Eintauchen der Zylindernocke 38 in die Ausnehmung 39 drückt die Zylindernocke 38 die Federplatte 52 vorerst zurück. Die Zylindernocke 38 greift sodann an der Steuerfläche bzw. Steuerkante 41 der Ausnehmung 39 an und verschiebt die Sperrplatte 40 in Richtung auf den Anschlußschieber 7, also in die Sperrstellung, in der die Sperrnase 42 in die Ausnehmung 43 eingreift. Die Federplatte 52 übt ständig eine Kraft gegen die Zylindernocke 38 aus und verhindert, daß eine Position der Zylindernocke 38 gegenüber der Steuerkante 41 stationär bleibt, die eine Selbsthemmung in einer Totpunktlage bewirken könnte. In dieser Lage wäre eine Notöffnung über den Schieber 44 nicht möglich, weil etwa außen der Schlüssel nicht abgezogen wurde und der Schließzylinder in der Zylindernockenposition nach Fig. 3a verbleibt. Durch die gefederte Platte 52 wird die Zylindernocke 38 auch bei zu früh beendetem Sperrvorgang derart weitergedreht, daß sie mit Sicherheit außerhalb der Ausnehmung 39 liegt, also eine Selbsthemmung vermieden wird.In the recess 39 of the locking plate 40 is a spring plate 52 which is biased by spring force against the lock cylinder. When the cylinder cam 38 is immersed in the recess 39, the cylinder cam 38 presses the spring plate 52 back for the time being. The cylinder cam 38 then engages the control surface or control edge 41 of the recess 39 and displaces the locking plate 40 in the direction of the connecting slide 7, that is to say into the locking position in which the locking lug 42 engages in the recess 43. The spring plate 52 constantly exerts a force against the cylinder cam 38 and prevents a position of the cylinder cam 38 from the control edge 41 remains stationary, which could cause self-locking in a dead center position. In this position, an emergency opening via the slide 44 would not be possible because the key was not removed from the outside and the locking cylinder was in the cylinder cam position 3a remains. Due to the spring-loaded plate 52, the cylinder cam 38 is further rotated, even if the locking process is ended too early, in such a way that it lies with certainty outside the recess 39, ie self-locking is avoided.
