Abstract

A latch (3) and lock (4) for a door are withdrawn simultaneously by the lever (7) attached to the shaft (2). This causes a thrust rod (8) attached to the lock to move against the force of a spring (5). A ratchet (10 to 12) ensures that the rod and the lock are held in the furthest withdrawn position. When the door is closed, the ratchet is released by a position sensor (6) and the spring engages the lock independently of key operation. An electromagnet is also provided.

Das simultane Einziehen von Falle und Riegel wurde durch die sogenannten Panikschlösser bekannt, welche von einer Schlosseite her ohne Schlüssel durch blosse Betätigung des Türdrückers geöffnet werden können.The invention relates to a door lock according to the preamble of claims 1 and 15. In such door locks by Actuation of the lever handle not only the latch, but also the bolt is pulled in, which is otherwise only possible by turning the key separately or by electromagnetic or motor means can be reached. The simultaneous retraction of the trap and Bolt became known through the so-called panic locks, which from a lock side without a key through bare Actuation of the door handle can be opened.

Durch die DE-A-30 50 356 ist beispielsweise ein derartiges Panikschloss bekanntgeworden, bei dem über einen Hebelmechanismus Falle und Riegel bei Betätigung des Türdrückers auf der Panikseite gleichzeitig eingezogen werden. Während die Falle beim Schliessen der Türe üblicherweise wiederum in das Schliessblech einrastet, wurde dem Wiederverschliessen des Riegels bisher keine grosse Beachtung geschenkt. Dies trifft insbesondere für einbruchhemmende Schlösser mit mehreren gesperrten Riegeln zu.DE-A-30 50 356 is one such example Panic lock became known in which a lever mechanism The latch and bolt open when the lever handle is operated the panic side are drawn in at the same time. While the Fall into the door when you close the door Closing plate snaps into place, was the reclosing of the Riegel has not paid much attention so far. This is true especially for burglar-resistant locks with several locked bars.

Durch die DE-A-41 10 556 ist ein gattungsmässig vergleichbares Türschloss bekannt geworden, in dessen Schlossgehäuse ein Kraftspeicher in der Form einer Druckfeder angeordnet ist. Der Kraftspeicher ist durch Öffnungsbetätigung des Schlosses aufladbar und durch Auflaufen eines Tasters am Türrahmen freigebbar. Mit Hilfe des Kraftspeichers ist der Riegel wiederum in die Schliessstellung ausfahrbar. Als Getriebe zum Betätigen des Riegels dient primär ein Zahnstangen-/Zahnradgetriebe, das mit einem Klinkenzahn gesperrt werden kann. Abgesehen von der aufwendigen Getriebeanordnung hat dieses Gesperre den Nachteil, dass jeweils nur innerhalb der vorgegebenen Zahnteilung gesperrt werden kann. DE-A-41 10 556 is a generic comparable Door lock became known in its lock case an energy accumulator arranged in the form of a compression spring is. The lift mechanism is activated by opening the Lock rechargeable and by pressing a button on Door frame can be released. With the help of the energy accumulator The latch can be extended to the closed position. As Gearbox for actuating the bolt is primarily a rack and pinion gear, that locked with a ratchet tooth can be. Apart from the complex gear arrangement this locking mechanism has the disadvantage that only within the specified tooth pitch can be blocked.

Es ist daher eine Aufgabe der Erfindung, ein Türschloss der eingangs genannten Art zu schaffen, bei dem der Riegel nicht nur durch Drehen des Nussteils einziehbar ist, sondern bei dem beim Schliessen der Türe wiederum eine automatische Selbstverriegelung mit voll ausgefahrenem Riegel eintritt. Das Schloss soll einen hohen Grad an Manipulationssicherheit und Betriebssicherheit aufweisen, und es soll den Antrieb von Nebenschlössern auf einfache Weise ermöglichen. Diese Aufgabe wird erfindungsgemäss mit einem Türschloss erreicht, das die Merkmale der Ansprüche 1 und 15 aufweist.It is therefore an object of the invention to provide a door lock to create the type mentioned, in which the bolt is not is only retractable by turning the nut part, but at an automatic one when the door is closed Self-locking occurs with the bolt fully extended. The lock is said to have a high level of tamper resistance and operational reliability, and it is intended to drive Enable locks in a simple way. This task is achieved according to the invention with a door lock that the Features of claims 1 and 15.

Bei der Getriebebetätigung zum Einziehen des Riegels muss die Kraft der Vorspannfeder überwunden werden. Diese wirkt ersichtlicherweise als Kraftspeicher, wobei das Gesperre eine Entspannung der Vorspannfeder verhindert bzw. von der Relativlage des Positionsfühlers abhängig macht. Mit Hilfe des Positionsfühlers und der Falle kann die vollständige Schliessstellung der Türe ermittelt werden, wonach die Vorspannfeder entspannt wird und der Riegel über das Getriebe wiederum ausgefahren wird. Da der Riegel wenigstens in einem Endabschnitt seiner Rückzugsbewegung in jeder Rückzugsposition arretierbar ist, kann die Türe bei entsprechend breitem Luftspalt zwischen Rahmen und Türe auch ohne vollständiges Einziehen des Riegels in den Schlosskasten geöffnet werden. Ein automatisches Verriegeln beim Wiederschliessen der Türe ist trotzdem gewährleistet.When actuating the gearbox to pull in the bolt, the Force of the bias spring can be overcome. This works evidently as an energy store, the locking mechanism being a Relaxation of the bias spring prevented or from the relative position of the position sensor. With the help of Position sensor and the trap can be the complete Closing position of the door can be determined, after which the Preload spring is released and the bolt on the gear is extended again. Since the bar is at least in one End portion of its retraction movement in any retreat position can be locked, the door can be wide enough Air gap between frame and door even without a complete one Pulling the bolt into the lock case can be opened. Automatic locking when the door is closed again is still guaranteed.

Funktional besonders einfach ist das Türschloss auch dadurch, dass das Getriebe einen mit dem Nussteil verbundenen Nussschwenkhebel aufweist, der an einer linear verschiebbaren Schubstange angreift, wobei die Schubstange über eine Führungskulisse mit dem Riegel verbunden ist und die Vorspannfeder und das Gesperre an der Schubstange angreifen. Die lineare Schubstangenbewegung lässt sich besonders einfach auf Nebenschlösser übertragen. Um bei der Betätigung des Schlosses ein zu grosses Drehmoment am Nussteil zu vermeiden, muss das Getriebe ein bestimmtes Uebersetzungsverhältnis aufweisen. Mit der linearen Schubstange kann ein genügend grosser Weg zurückgelegt werden, um den Riegel ohne übermässigen Kraftaufwand zu betätigen. Die Führungskulisse sorgt für eine Aenderung der Bewegungsrichtung von der linear verschiebbaren Schubstange auf den ebenfalls linear verschiebbaren Riegel. Vorzugsweise bewegt sich dabei die Schubstange in vertikaler Richtung, wobei eine 90° Umlenkung der Bewegung auf den horizontal verschiebbaren Riegel stattfindet. Selbstverständlich wären aber auch andere Getriebearten grundsätzlich denkbar. So könnte der Antrieb des Riegels auch über ein Zahnradgetriebe erfolgen und die Vorspannfeder könnte auf einer Getriebeachse als Spiralfeder oder dergleichen angeordnet sein.The door lock is also functionally particularly simple because that the gearbox has a nut pivot lever connected to the nut part has on a linearly displaceable Push rod attacks, the push rod over a guide link is connected to the bolt and the bias spring and attack the locking mechanism on the push rod. The linear push rod movement is particularly easy to open Transfer locks. To operate the lock Avoid excessive torque on the nut part the gearbox has a specific gear ratio. With the linear push rod one can do enough great distance to be covered without excessive To use force. The management backdrop ensures for a change in the direction of movement from the linear sliding push rod on the also linear sliding Bars. Preferably, the moves Push rod in the vertical direction, with a 90 ° deflection the movement on the horizontally movable bolt takes place. Of course, other types of gear would also be basically conceivable. So the drive of the Riegel also done via a gear transmission and the Preload spring could be on a gear axis as a spiral spring or the like may be arranged.

Eine zusätzliche Sicherheitsfunktion kann erreicht werden, wenn die Führungskulisse relativ zur Bewegungsrichtung des Riegels derart verläuft, dass das Getriebe bei ausgefahrenem Riegel selbsthemmend ist, wobei der Riegel nicht eindrückbar ist. Dies wird auf einfachste Weise dadurch erreicht, dass die Führungskulisse im Endabschnitt parallel zur Schubstange, also im rechten Winkel zur Bewegungsrichtung des Riegels verläuft. Selbst bei einer Manipulation am Türrahmen kann dadurch der Riegel in der Schliessstellung nicht eingedrückt werden.An additional safety function can be achieved if the guide link relative to the direction of movement of the Riegel runs in such a way that the transmission when extended The latch is self-locking, the latch cannot be pressed in is. This is achieved in the simplest way by the fact that the guide link in the end section parallel to the push rod, so at right angles to the direction of movement of the bolt runs. Even if the door frame is tampered with this prevents the bolt from being pushed into the closed position will.

Die besonders vorteilhafte und völlig stufenlose Gesperrefunktion wird dadurch erreicht, dass das Gesperre einen an der Schubstange angeordneten Sperrstab aufweist, der durch eine Oeffnung in einer feststehenden, jedoch kippbar gelagerten Sperrplatte dringt, wobei Sperrstab und Sperrplatte innerhalb der beiden Endpositionen der Schubstange stufenlos gegeneinander verspannbar sind. Die Sperrplatte kann dabei über ein mit dem Positionsfühler in Wirkverbindung stehendes Entriegelungselement aus einer Sperrstellung, in welcher der Sperrstab in der Oeffnung verkantet, in eine Lösestellung bewegbar sein, in der sich der Sperrstab frei in Oeffnung bewegen kann. Durch das Verkanten der Sperrplatte am Sperrstab wird ein hoher Grad von Betriebssicherheit erreicht. Trotzdem wird für das Lösen der Sperre nur eine geringe Kraft erfordert. Es wäre aber selbstverständlich auch denkbar, andere klemmschlüssige Gesperrearten einzusetzen. The particularly advantageous and completely stepless locking function is achieved in that the ratchet is on the push rod arranged locking rod, which by an opening in a fixed, but tiltable Lock plate penetrates, locking bar and lock plate stepless within the two end positions of the push rod are braced against each other. The locking plate can via a functionally connected to the position sensor Unlocking element from a locked position, in which the Locking rod tilted in the opening, in a release position be movable, in which the locking rod is freely open can move. By tilting the locking plate on the locking rod a high degree of operational security is achieved. Nevertheless, only a small amount of force is required to release the lock required. Of course, it would also be conceivable use other types of locking devices.

Klemmschlüssige Gesperre lassen sich besonders einfach auch mit einem Exzenter erzielen. Schliesslich wären auch Kombinationen von verschiedenen Gesperrearten denkbar.Locking locks are also particularly easy achieve with an eccentric. After all, combinations would also be of different types of lock conceivable.

Das Entriegelungselement ist besonders vorteilhaft als Doppelhebel ausgebildet, der schwenkbar an der Falle gelagert ist. Der eine Arm des Doppelhebels steht dabei mit dem Positionsfühler in Wirkverbindung, während der andere Arm des Doppelhebels an einem Betätigungselement anliegt, das mit der Sperrplatte verbunden ist. Eine simultane Verschiebung von Falle und Positionierfühler bewirkt keine Beeinflussung des Betätigungselements, da sich die Relativlage des Doppelhebels bezogen auf die Vorschubebene der Falle nicht verändert. Dagegen bewirkt eine Relativverschiebung zwischen Falle und Positionierfühler eine Drehung des Doppelhebels und damit eine Beeinflussung des Betätigungselements, so dass die Sperrplatte in die Lösestellung geschwenkt werden kann. Das Lösen der Sperre bei einer Relativverschiebung zwischen Falle und Positionierfühler kann besonders vorteilhaft dazu ausgenutzt werden, dass ein Lösen der Sperren und damit ein Schliessen des Riegels erst dann überhaupt möglich ist, wenn die Falle wiederum in das Schliessblech eingefallen ist und wenn damit gewährleistet ist, dass die Türe in der richtigen Relativlage zentriert ist.The unlocking element is particularly advantageous as Double lever designed, which is pivotally mounted on the latch is. One arm of the double lever stands with the position sensor in operative connection while the other arm of the Double lever abuts an actuator that with the Lock plate is connected. A simultaneous shift from Trap and positioning sensor does not affect the Actuator, since the relative position of the double lever not changed in relation to the feed level of the trap. In contrast, a relative shift between the trap and Positioning sensor a rotation of the double lever and thus influencing the actuating element, so that the Locking plate can be pivoted into the release position. The Release the lock in the event of a relative shift between the trap and positioning sensor can be used particularly advantageously for this purpose that a release of the locks and thus one Closing the latch is only possible if the latch has again fallen into the striking plate and if this ensures that the door is in the correct Relative position is centered.

Um zu erreichen, dass das Entriegelungselement unabhängig von den spezifischen Betriebsbedingungen stets mit der gleichen Kraft betätigt wird, kann es mit einer Spannfeder verbunden sein, welche beim Einziehen der Falle spannbar ist. Dabei kann das Entriegelungselement in einer Spannstellung arretierbar sein und es kann bei einer Relativverschiebung zwischen Falle und Positionsfühler aus der Spannstellung lösbar sein, wobei es an der Sperrplatte anschlägt und diese in die Lösestellung bewegt. Das Entriegelungselement übernimmt dabei eine ähnliche Funktion, wie der Schlagbolzen an einem automatischen Gewehr, der stets automatisch gespannt und beim Durchziehen des Abzugs wieder ausgelöst wird. Ein derartiges Entriegelungselement kann ebenfalls als Doppelhebel ausgebildet sein, der schwenkbar aber relativ zur Falle ortsfest am Schlossgehäuse gelagert ist. Die Spannfeder kann dabei auf der Schwenkachse angeordnet sein. Der eine Arm des Doppelhebels liegt im Schwenkbereich des Nussschwenkhebels und der andere Arm des Doppelhebels liegt im Kippbereich der Sperrplatte, so dass der Doppelhebel beim Drehen des Nussschwenkhebels gegen die Kraft der Spannfeder von der Sperrplatte wegschwenkbar ist. Neben dem Doppelhebel kann eine Sperrklinke angeordnet sein, welche ihn in der Spannstellung arretiert.To achieve that the unlocking element regardless of the specific operating conditions always with the same Force is actuated, it can be connected to a tension spring which can be tensioned when the trap is pulled in. Here the unlocking element can be locked in a clamping position and it can be with a relative shift between latch and position sensor from the clamping position be detachable, it strikes the locking plate and this moved to the release position. The unlocking element takes over a similar function to the firing pin an automatic rifle that is always automatically cocked and is triggered again when the trigger is pulled. Such an unlocking element can also be used as Be designed double lever, which is pivotable but relative to Case is mounted on the lock housing. The tension spring can be arranged on the pivot axis. One arm of the double lever lies in the swivel range of the nut swivel lever and the other arm of the double lever is in the tilt area the locking plate so that the double lever when turning the Nut pivot lever against the force of the tension spring from the Lock plate is pivoted away. In addition to the double lever a pawl can be arranged, which him in the clamping position locked.

Die Sperrklinke kann unmittelbar über die Falle gesteuert werden. Vorzugsweise wird jedoch an der Falle ein spezieller Steuerhebel schwenkbar gelagert, mit dem die Sperrklinke steuerbar ist. Dies ermöglicht es, den Positionsfühler ganz von der Falle zu entkoppeln, wobei er zusammen mit der Falle zurückziehbar ist, jedoch bei einer Relativverschiebung zwischen Falle und Positionsfühler beim Ausfahren der Falle den Steuerhebel aktiviert und dabei die Sperrklinke löst. Zu diesem Zweck kann der Positionsfühler eine Steuerkurve aufweisen, welche mit dem Steuerhebel derart zusammenwirkt, dass die Sperrklinke erst in der Endphase der Ausfahrbewegung der Falle gelöst wird.The pawl can be controlled directly via the trap will. However, a special one is preferred on the trap Control lever pivoted with which the pawl is controllable. This enables the position sensor to be completely decouple from the trap, being together with the trap is retractable, but with a relative shift between the latch and position sensor when the latch is extended activated the control lever and thereby released the pawl. To For this purpose, the position sensor can use a control curve which cooperates with the control lever in such a way that the pawl only in the final phase of the extension movement the trap is solved.

Eine vielseitige Verwendbarkeit des Türschlosses und verschiedene elektrische Ansteuerungen der Zutrittskontrolle werden dadurch erreicht, dass das Nussteil in einen inneren und in einen äusseren, unabhängig voneinander drehbaren Mitnehmerarm unterteilt ist, wobei der Nussschwenkhebel zwischen den beiden Mitnehmerarmen angeordnet ist. Auf beiden Seiten des Nussschwenkhebels ist im Schwenkbereich der Mitnehmerarme je ein Mitnehmerelement angeordnet, von denen wenigstens eines manuell durch Schlüsselbetätigung oder elektromagnetisch durch ein Antriebselement aus einer Leerlaufstellung ausserhalb des Drehbereichs des Mitnehmerarms in eine Eingriffstellung innerhalb des Drehbereichs des Mitnehmerarms schaltbar ist. Diese Massnahme erlaubte es, dass an einem Schloss eingestellt werden kann, ob sich die Türe einwärts oder auswärts öffnen soll. Durch entsprechende Einstellung des Mitnehmerelements erhält das Türschloss ausserdem eine Panikfunktion, so dass eine Türe ohne Ausgangskontrolle jederzeit von einer Seite her mit einer einzigen, kontinuierlichen Handbewegung freigegeben werden kann. Die Panikseite kann dabei durch entsprechende Einstellung frei gewählt werden. Die Betätigung der Panikfunktion kann über einen Mikroschalter für die Auswertung durch ein externes Ueberwachungssystem aufgezeichnet werden.A versatile use of the door lock and various electrical controls for access control are achieved in that the nut part in an inner and in an outer, independently rotatable Driver arm is divided, the nut pivot lever is arranged between the two driver arms. On both Sides of the nut swivel lever is in the swivel range Driver arms each arranged a driver element, of which at least one manually by key actuation or electromagnetically by a drive element from an idle position outside the range of rotation of the driving arm in an engagement position within the range of rotation of the driver arm is switchable. This measure allowed that on a lock can be set whether the door should open inwards or outwards. By appropriate The door lock receives the setting of the driver element also a panic function, so that a door without exit control at any time from one side with one single, continuous hand movement can. The panic page can be adjusted accordingly can be freely chosen. The operation of the panic function can be used for evaluation via a microswitch an external monitoring system can be recorded.

Das erfindungsgemässe Türschloss kann an einer Türe als Hauptschloss allein verwendet werden. Es eignet sich aber auch besonders vorteilhaft als Hauptschloss für den Antrieb wenigstens eines Nebenschlosses, das ebenfalls einen gegen die Kraft einer Vorspannfeder einziehbaren Riegel aufweist. In der Regel verfügt eine Türe über je ein unteres und ein oberes Nebenschloss. Durch die zwangsweise synchrone Bewegung aller Riegel kann die richtige Verriegelung der Türe mit einem einzigen Kontakt elektrisch überwacht werden. Die Kupplungsstange für den Antrieb der Nebenschlösser wird besonders vorteilhaft in einem U-förmigen Schlossstulp geführt. Dieser ist vorteilhaft aus einem besonders harten Stahl gefertigt, so dass die Schubstange von aussen praktisch nicht zugänglich ist. Die beiden Schenkel des U-förmigen Schlossstulps sind gegen das Schloss gerichtet. Eine besonders manipulationssichere Befestigung des Schlossstulps kann erreicht werden, wenn dieser mittels Schrauben an der Stirnseite der Türe befestigt ist, wobei er sich im Bereich der Schrauben mit einem von einer Schraube durchdrungenen Mittelsteg an der Stirnseite abstützt und wobei die Kupplungsstange im Bereich des Mittelsstegs zweiteilig ausgebildet ist. Der Schraubenschaft ist dabei vollständig in den Mittelsteg eingebettet. Eine derartige Stulpkonstruktion kann ohne weiteres auch bei anderen Türen ohne die erfindungsgemässe Riegelkonstruktion eingesetzt werden. Zum Schutz gegen Verschmutzung und zur Manipulationssicherung kann der Schlossstulp noch durch ein Abdeckblech abgedeckt sein, so dass für die Kupplungsstange praktisch ein geschlossener Kanal entsteht.The door lock according to the invention can be used on a door Main lock can be used alone. But it is suitable also particularly advantageous as a main lock for the drive at least one secondary lock, which also one against has the force of a bias spring retractable latch. As a rule, a door has one lower and one each upper secondary lock. Due to the forced synchronous movement all bolts can lock the door correctly be monitored electrically from a single contact. The Coupling rod for driving the secondary locks particularly advantageous in a U-shaped lock faceplate guided. This is advantageous from a particularly hard one Steel made so the push rod is practical from the outside is not accessible. The two legs of the U-shaped Lock cuffs are directed against the lock. A special one Tamper-proof fastening of the lock cuff can can be achieved by using screws on the front the door is fastened, whereby it is in the area of Screws with a central web penetrated by a screw is supported on the front and the coupling rod is formed in two parts in the region of the central web. Of the Screw shaft is completely in the middle bar embedded. Such a faceplate construction can without further also with other doors without the inventive Bolt construction can be used. To protect against Pollution and tamper protection can The lock plate can still be covered by a cover plate, see above that for the coupling rod practically a closed one Channel emerges.

In bestimmten Fällen kann auf eine separate Falle zum Zentrieren der Türe verzichtet werden. Das Türschloss ist dann nur als Riegelschloss ausgebildet, dessen Funktion im übrigen aber genau gleich ist, wie bei einem kombinierten Fallen-Riegelschloss.In certain cases, a separate trap can be used for centering the door can be dispensed with. The door lock is then only designed as a deadbolt lock, its function in the rest but is exactly the same as with a combined latch-and-bolt lock.

Anhand der Fig. 1 werden zunächst nur die wichtigsten Bauteile des Türschlosses erläutert, während weitere Details auch noch aus Fig. 2 ersichtlich sind. Die beweglichen Teile des Türschlosses 1 sind in einem Schlossgehäuse 24 untergebracht, das an mehreren, verteilt angeordneten Gewindebüchsen 25 mit einem hier nicht dargestellten Deckel verschlossen werden kann. Die elektrischen bzw. elektronischen Teile sind durch Entfernen einer stirnseitigen Flanschplatte 48 separat zugänglich.1, only the most important components are initially shown of the door lock explained while further details as well are still apparent from Fig. 2. The moving parts of the Door lock 1 are housed in a lock housing 24, on several, distributed threaded bushes 25 with a cover not shown here can be closed can. The electrical or electronic parts are through Removal of an end flange plate 48 separately accessible.

Das Türschloss wird über ein drehbeweglich gelagertes Nussteil 2 betätigt, in das von beiden Seiten her auf bekannte Weise ein Türdrücker eingesteckt werden kann. Das Nussteil ist dabei für jede Schlosseite aufgeteilt, in je einen separat verschwenkbaren Mitnehmerarm 15. Jeder Mitnehmerarm ist mit Hilfe einer Vorspannfeder 30 gegen die Drehbewegung des Nussteils vorgespannt. Zwischen den beiden Mitnehmerarmen 15 ist frei schwenkbar ein Nussschwenkhebel 7 gelagert. Auch der Nussschwenkhebel ist mit Hilfe einer Vorspannfeder 31 in die gleiche Richtung vorgespannt wie die beiden Mitnehmerarme 15. Auf beiden Seiten des Nussschwenkhebels 7 ist je ein Mitnehmerelement 16 an einem Gelenk schwenkbar gelagert. Wenigstens eines dieser Mitnehmerelemente ist mit Hilfe einer Vorspannfeder 33 derart vorgespannt, dass es ausserhalb des Schwenkbereiches des ihm zugeordneten Mitnehmerarms 15 liegt. Bei einer Betätigung dieses Mitnehmerarms dreht sich dieser somit gegen die Kraft der Vorspannfeder 30 im Leerlauf, ohne dass sich der Nussschwenkhebel 7 mitdreht.The door lock is attached to a rotating nut part 2 operated, in the known from both sides Way a door handle can be inserted. The nut part is divided into one for each side of the lock separately pivotable driver arm 15. Each driver arm is against the rotational movement by means of a biasing spring 30 of the nut part biased. Between the two driver arms 15, a nut pivot lever 7 is pivoted freely. Also the nut pivot lever is in with the help of a biasing spring 31 biased in the same direction as the two drive arms 15. On both sides of the nut pivot lever 7 is one Driver element 16 is pivotally mounted on a joint. At least one of these driver elements is with the help of a Preload spring 33 biased such that it is outside the Pivotal range of the driver arm 15 assigned to it lies. When this driver arm is actuated, it rotates thus against the force of the bias spring 30 at idle without that the nut pivot lever 7 rotates as well.

Damit bei einer Drückerbetätigung auch der Nussschwenkhebel 7 in Pfeilrichtung a geschwenkt wird, muss das Mitnehmerelement 16 gegen die Kraft der Vorspannfeder 33 in den Schwenkbereich des Mitnehmerarms 15 gebracht werden. Diese Bewegung kann entweder durch Schlüsselbetätigung oder durch ein über eine Zutrittskontrolle ansteuerbares Antriebselement erfolgen. Ein Zylinderschloss 26 ist mit seinem Schlossbart 49 im Bereich einer Betätigungsplatte 44 angeordnet. Die Betätigungsplatte ist durch nicht dargestellte Federelemente in einer neutralen Betriebslage gehalten. Sie kann durch Drehung des Zylinderschlosses in beide Drehrichtungen betätigt werden. Bei einer Drehung des Zylinderschlosses in Oeffnungsrichtung wird die Betätigungsplatte 44 in Fig. 2 etwas angehoben. Dabei wird ein Zwischenhebel 43 ebenfalls im Uhrzeigersinn gedreht, der seinerseits das Mitnehmerelement 16 in Pfeilrichtung e schwenkt. Das Mitnehmerelement gelangt dabei in den Schwenkbereich des Mitnehmerarms 15, so dass sich der Nussschwenkhebel mitdreht.So that when the handle is actuated, the nut pivot lever 7 is pivoted in the direction of arrow a, the driver element 16 against the force of the bias spring 33 in the swivel range of the driver arm 15 are brought. This movement can either by key actuation or by using one Access control drive element can be controlled. A Cylinder lock 26 is in the area with its lock bit 49 an actuating plate 44 arranged. The actuator plate is in a neutral by spring elements, not shown Operating situation kept. It can be done by turning the cylinder lock can be operated in both directions. At a Rotation of the cylinder lock in the opening direction is the Actuating plate 44 slightly raised in FIG. 2. Doing so an intermediate lever 43 is also rotated clockwise, the in turn the driver element 16 in the direction of arrow e pivots. The driver element comes into the swivel range of the driver arm 15, so that the nut pivot lever turns with.

Die Einkupplung des Mitnehmerelements 16 kann aber auch elektromagnetisch erreicht werden. Ueber ein hier nicht näher dargestelltes Zutrittskontrollsystem wird beim Vorliegen einer Zutrittsberechtigung der Elektromagnet 27 aktiviert. Dabei wird ein Magnetkipphebel 42 in Fig. 2 im Gegenuhrzeigersinn gedreht, der seinerseits wieder den Zwischenhebel 43 im Uhrzeigersinn dreht. Die Wirkung auf das Mitnehmerelement 16 ist ersichtlicherweise die gleiche wie beim Drehen des Zylinderschlosses 26. Der Vorteil der elektromagnetischen Betätigung besteht darin, dass das Schloss zur Betätigung sofort freigegeben wird.The coupling of the driver element 16 can also can be reached electromagnetically. Not about one here shown access control system is available an access authorization of the electromagnet 27 is activated. Here, a magnetic rocker arm 42 in FIG. 2 turns counterclockwise rotated, which in turn the intermediate lever 43rd rotates clockwise. The effect on the driver element 16 is obviously the same as when turning the Cylinder lock 26. The advantage of electromagnetic Actuation is that the lock is for actuation is released immediately.

Die Betätigungsplatte 44 kann aber auch bewegt werden, indem das Zylinderschloss in Figur 2 in Schliessrichtung gedreht wird. Dabei wird die Betätigungsplatte etwas im Uhrzeigersinn abgekippt, so dass sie die durch feine Linien angedeutete Position einnimmt. Dabei wird eine Mikroschalteinheit 28 betätigt, welche die Stromzufuhr zum Elektromagneten 27 unterbricht und dadurch den Zutritt über ein Zutrittskontrollsystem ausser Kraft setzt. Ersichtlicherweise ist so die Schlüsselbetätigung dem Zutrittskontrollsystem übergeordnet. Selbstverständlich kann über die Mikroschaltereinheit die Schlüsselöffnung überwacht und protokolliert werden.The actuating plate 44 can also be moved by the cylinder lock in Figure 2 rotated in the closing direction becomes. The actuating plate turns slightly clockwise tilted so that it is the one indicated by fine lines Takes position. In this case, a micro-switching unit 28 actuated, which the power supply to the electromagnet 27th interrupts and thereby access via an access control system overrides. Obviously, that's the way it is Key actuation overrides the access control system. Of course, the Key opening can be monitored and logged.

Die Mikroschaltereinheit 28 kann aber auch dazu verwendet werden, eine allenfalls vorhandene Notausgangssicherung ausser Funktion zu setzen. Derartige Sicherungen dienen dazu, dass Notausgänge beispielsweise durch Anschluss eines Flächenmagnets gesperrt oder nur unter bestimmten Extrembelastungen geöffnet werden können. Bei Stromausfall ist der Notausgang jedoch immer offen. Eine derartige Notausgangssicherung könnte durch Schlüsselbetätigung ausser Funktion gesetzt werden. Der Anschluss der elektrischen Kontakte zur Mikroschaltereinheit bzw. zum Elektromagneten erfolgt über einen nur angedeuteten Stecker 52 am Schlossgehäuse 24.The microswitch unit 28 can also be used for this an existing emergency exit security to put out of function. Such fuses are used to that emergency exits, for example, by connecting a surface magnet locked or only under certain extreme loads can be opened. In the event of a power failure However, the emergency exit is always open. Such emergency exit security could become inoperable by key operation be set. The connection of the electrical contacts to the Microswitch unit or to the electromagnet takes place via an only indicated connector 52 on the lock housing 24.

Der Nussschwenkhebel 7 ist als Doppelhebel ausgebildet und verfügt über ein Hebelunterteil 38 und ein Hebeloberteil 39. Das Hebelunterteil 38 greift in eine Schubstange 8, die gemäss Fig. 1 als kastenförmiges Hohlteil ausgebildet ist. Die Schubstange ist mit einem Stift 37 oder mit einer Rolle versehen, an dem das Hebelunterteil 38 angreift, wobei die Schubstange in Pfeilrichtung b verschoben werden kann. An ihrem oberen Ende wirkt die Schubstange 8 mit einem feststehenden Federdorn 50 zusammen, der gleichzeitig eine als Druckfeder ausgebildete Vorspannfeder 5 trägt. Die Vorspannfeder presst die Schubstange nach unten, in die in Fig. 2 dargestellte Position. Im unteren Bereich weist die Schubstange eine Führungskulisse 9 auf, die mit einem Riegel 4 zusammenwirkt.The nut pivot lever 7 is designed as a double lever and has a lower lever part 38 and an upper lever part 39. The lower lever part 38 engages in a push rod 8 which 1 is designed as a box-shaped hollow part. The push rod is with a pin 37 or with a roller provided, on which the lever lower part 38 engages, the Push rod can be moved in the direction of arrow b. On the upper end of the push rod 8 acts with a fixed Spring mandrel 50 together, which is also a Compression spring trained bias spring 5 carries. The preload spring presses the push rod down into the one in Fig. 2 position shown. The push rod has in the lower area a guide link 9, which with a bolt 4th cooperates.

Der Riegel 4 ist in einer Riegelführung 35 im rechten Winkel zur Schubstange 8 beweglich gelagert. Zu diesem Zweck verfügt der Riegel über einen Riegelbolzen 34, der in je einem Führungsschlitz 36 auf beiden Seiten der Riegelführung geführt ist. Gleichzeitig ist der Riegelbolzen 34 aber auch in der Führungskulisse 9 geführt, so dass ersichtlicherweise eine Verschiebung der Schubstange 8 in Pfeilrichtung b ein Einziehen des Riegels 4 in Pfeilrichtung d bewirkt. Die Führungskulisse 9 hat einen geraden oberen Abschnitt, so dass ersichtlicherweise das Getriebe in diesem Bereich zwar durch Schwenken des Nussschwenkhebels 7, aber nicht durch Eindrücken des Riegels 4 betätigt werden kann. Durch diese Anordnung der Führungskulisse 9 wirkt das Getriebe in eine Richtung selbsthemmend.The bolt 4 is in a bolt guide 35 at a right angle movably mounted to the push rod 8. Decreed for this purpose the bolt via a locking bolt 34, each in one Guide slot 36 on both sides of the latch guide is led. At the same time, the locking bolt 34 is also performed in the guide slot 9, so that obviously a displacement of the push rod 8 in the direction of arrow b Pulling the bolt 4 in the direction of arrow d causes. The Guide link 9 has a straight upper section, so that obviously the transmission in this area Swiveling the nut pivot lever 7, but not by pushing it in the bolt 4 can be operated. Through this Arrangement of the guide link 9 acts in a gear Direction self-locking.

Am oberen Ende der Schubstange 8 ist parallel zu deren Bewegungsrichtung ein Sperrstab 10 angeordnet, der beispielsweise einen quadratischen Querschnitt aufweisen kann. Dieser Sperrstab dringt durch die Oeffnung 11 einer im Schlosskasten gelagerten Sperrplatte 12. Die Sperrplatte kann eine begrenzte Schwenkbewegung ausführen, so dass sich der Sperrstab 10 in der Oeffnung 11 verkantet. Zu diesem Zweck ist die Sperrplatte 12 mit Hilfe einer Vorspannfeder 32 abgefedert, so dass sie ohne zusätzliche Einwirkung stets eine Position einnimmt, in welcher der eindringende Sperrstab in der Oeffnung verkantet. At the upper end of the push rod 8 is parallel to the latter Movement direction arranged a locking rod 10, for example can have a square cross section. This Locking rod penetrates through the opening 11 in the lock case stored locking plate 12. The locking plate can be a limited Carry out a pivoting movement so that the locking rod 10 canted in the opening 11. For this purpose, the locking plate 12 cushioned by means of a biasing spring 32, so that they always have a position without additional influence occupies in which the penetrating locking rod in the Opening tilted.

Zum Lösen der Sperre muss ein Betätigungselement 14 bewegt werden, das an einem Ende der Sperrplatte 12 befestigt ist. Das Betätigungselement ist als einseitig aufgelegter Winkel mit einer bestimmten Schenkellänge ausgebildet. Die Aktivierung des Betätigungselements 14 erfolgt über einen Positionsfühler 6 und über einen Doppelhebel 13 und zwar über eine Relativbewegung zwischen Falle und Positionsfühler.An actuating element 14 must be moved in order to release the lock be attached to one end of the locking plate 12. The actuator is a one-sided angle trained with a certain leg length. The activation of the actuating element 14 takes place via a position sensor 6 and via a double lever 13, namely via a Relative movement between the latch and position sensor.

Der Doppelhebel 13 ist schwenkbar an einer Falle 3 gelagert. Die Falle 3 ist mit Hilfe einer Vorspannfeder 29 vorgespannt, so dass sie im Ruhestand stets aus dem Schlosskasten gepresst wird. Das Hebeloberteil 39 des Nussschwenkhebels 7 greift in die Falle 3 ein und beim Drehen des Nussschwenkhebels wird die Falle gegen die Kraft der Vorspannfeder 29 in Pfeilrichtung c gleichzeitig mit dem Riegel 4 eingezogen. Der Nussschwenkhebel 7 bzw. das Hebeloberteil 39 legt allerdings zunächst einen bestimmten Leerlauf zurück, bevor die Falle eingezogen wird. Dies ergibt sich daraus, dass der Riegel einen grösseren Rückzugsweg zurücklegen muss als die Falle. Der Leerlauf ist so dimensioniert, dass der Rückzug der Falle erst dann beginnt, wenn der Riegel 4 die ausgefahrene Position der Falle 3 erreicht hat. Anschliessend verlaufen die Bewegungen simultan, wobei Falle und Riegel stets auf der gleichen Höhe bleiben. Der Entriegelungshebel 13 hat ein Hebelunterteil 40, das am Positionsfühler 6 befestigt ist und ein Hebeloberteil 41, das am Betätigungselement 14 anliegt. Das Hebeloberteil 41 kann zur Reduktion der Reibung auch durch eine Rolle ersetzt werden.The double lever 13 is pivotally mounted on a latch 3. The trap 3 is biased by means of a biasing spring 29, so that they are always pressed out of the lock case when retired becomes. The upper lever part 39 of the nut pivot lever 7 engages in the trap 3 and when turning the nut pivot lever the trap against the force of the bias spring 29 in the direction of the arrow c pulled in simultaneously with the bolt 4. The nut pivot lever 7 or the upper lever part 39 sets however first go back a certain idle before the trap is drawn in. This is because the latch must travel a longer distance than the trap. The idle speed is dimensioned such that the trap retracts only begins when the bolt 4 is in the extended position the case has reached 3. Then the Simultaneous movements, the latch and bolt always on the stay the same height. The unlocking lever 13 has a Lower lever part 40, which is attached to the position sensor 6 and a lever upper part 41, which rests on the actuating element 14. The lever upper part 41 can also reduce the friction be replaced by a role.

Ein Verschieben der Falle 3 bewirkt ersichtlicherweise auch eine simultane Verschiebung des Positionsfühlers 6, ohne dass der Doppelhebel 13 eine Schwenkbewegung ausführt. Erst eine Relativbewegung zwischen Falle 3 und Positionsfühler 6, also ein Zurückhalten des Positionsfühlers bei ausgefahrener Falle, führt zu einer Drehbewegung des Doppelhebels 13, wobei das Hebeloberteil 41 das Betätigungselement 14 nach oben drückt und damit die Sperrplatte entriegelt.Moving the trap 3 obviously also causes a simultaneous displacement of the position sensor 6 without the double lever 13 pivots. First one Relative movement between case 3 and position sensor 6, that is retention of the position sensor when extended Trap leads to a rotary movement of the double lever 13, wherein the lever upper part 41, the actuating element 14 upwards presses and unlocks the locking plate.

Das Türschloss 1 ist unmittelbar hinter einem etwa U-förmigen Schlossstulp 22 angeordnet. In diesem Schlossstulp ist auch eine Kupplungsstange 17 geführt, welche die Bewegung der Schubstange oben und unten auf Nebenschlösser überträgt. Ein derartiges Nebenschloss 18 ist beispielsweise in Fig. 5 dargestellt. Es besitzt ebenfalls eine Schubstange 20 mit einer Führungskulisse 21, wobei der Riegel 45 des Nebenschlosses 18 genau gleich geführt ist und bewegt wird wie im Hauptschloss. Eine Vorspannfeder 19 presst die Schubstange 20 nach unten, so dass der Riegel ausgefahren bleibt.The door lock 1 is immediately behind an approximately U-shaped Lock faceplate 22 arranged. In this lock faceplate is too guided a coupling rod 17, which the movement of the Transfers the push rod to the top and bottom locks. A such a secondary lock 18 is, for example, in FIG. 5 shown. It also has a push rod 20 a guide link 21, the bolt 45 of the secondary lock 18 is guided and moved in exactly the same way as in Main castle. A biasing spring 19 presses the push rod 20 down so that the latch remains extended.

Anhand der Fig. 3 und 4 wird nun die Funktion des erfindungsgemässen Türschlosses erläutert. Fig. 3 zeigt das Türschloss bei ganz niedergehaltenem Türdrücker. Die Falle 3 und der Riegel 4 sind dabei vollständig eingezogen. Die Schubstange 8 hat ihre obere Endposition erreicht und die Vorspannfeder 5 ist praktisch auf ihren maximalen Federweg zusammengepresst. Der Sperrstab 10 dringt mit seinem äussersten Ende gerade noch in die Oeffnung 11. Wird nun der Türdrücker losgelassen, so schwenkt der Nussschwenkhebel 7 unter der Einwirkung der Vorspannfeder 31 wieder in seine ursprüngliche Lage zurück, wobei auch die Falle 3 unter Einwirkung der Vorspannfeder 29 wiederum ausgefahren wird. Dagegen wird ein Zurückgleiten der Schubstange 8 unter der Einwirkung der Vorspannfeder 5 durch das Gesperre verhindert. Wie bereits erwähnt, ist es nicht erforderlich, dass zum Oeffnen und Entriegeln der Türe der Riegel vollständig in die in Fig. 3 dargestellte Position zurückgezogen werden muss. Es genügt, Falle und Riegel soweit zurückzuziehen, bis die Türe gerade geöffnet werden kann. Das Gesperre wird beim Loslassen des Türdrückers den Riegel in der jeweils angelaufenen Position festhalten.3 and 4, the function of the inventive Door lock explained. Fig. 3 shows the door lock with the door handle held down. The trap 3 and the Bolts 4 are fully retracted. The push rod 8 has reached its upper end position and the preload spring 5 is practically compressed to their maximum travel. The locking rod 10 penetrates straight at its extreme end still in the opening 11. If the lever handle is now released, so the nut pivot lever 7 pivots under the influence of Bias spring 31 back to its original position, wherein the trap 3 under the action of the bias spring 29th is extended again. On the other hand, the Push rod 8 under the action of the bias spring 5 the locking prevents. As already mentioned, it is not required to open and unlock the door of the Latch fully in the position shown in Fig. 3 must be withdrawn. It is enough to catch and catch so far withdraw until the door can be opened. The The lock is locked when the lever handle is released hold the position you have started.

Beim Schliessen der Türe wird gemäss Fig. 4 zunächst die angeschrägte Falle 3 durch das Schliessblech 23 gegen die Kraft der Vorspannfeder 29 zurückgedrückt. Ein Betätigen des Türdrückers ist dabei nicht erforderlich, da sich die Falle 3 unabhängig vom Nussschwenkhebel 7 bewegen kann. Alternativ kann selbstverständlich auch der Türdrücker betätigt werden, um die Falle 3 einzuziehen. Der Riegel bleibt dabei unverändert in der zurückgezogenen Position. Durch die Vorspannfeder 29 wird die Falle bei geschlossener Türe in die am Schliessblech angeordnete Fallenöffnung 46 gepresst. Dabei findet eine Zentrierung der Türe relativ zum Türrahmen statt. Ein Widerlager 47 unterhalb der Fallenöffnung 46 sorgt jedoch dafür, dass der Positionsfühler 6 nicht mehr vollständig zusammen mit der Falle ausgefahren werden kann. Diese Relativverschiebung zwischen Falle und Positionsfühler führt zu einer Drehung des Doppelhebels 13 und damit zu einer Beeinflussung des Betätigungselements 14. Der Sperrstab 10 wird dabei durch die Bewegung der Sperrplatte in seiner Oeffnung befreit und die Vorspannfeder 5 kann die Schubstange in Pfeilrichtung f nach unten drücken. Ueber die Führungskulisse 9 wird dadurch ersichtlicherweise der Riegel 4 in Pfeilrichtung g ausgefahren. Der Riegel dringt dabei mit einer durch die entsprechenden Sicherheitsnormen vorgeschriebenen Eindringtiefe von beispielsweise 15 mm in die Riegelöffnung 51. Der gleiche Vorgang findet auch an den über die Kupplungsstange 17 angesteuerten Nebenschlössern statt.4, when the door is closed, the beveled case 3 through the striking plate 23 against the Force of the bias spring 29 is pushed back. An actuation of the Lever handle is not necessary, as the latch 3 can move independently of the nut pivot lever 7. Alternatively the lever handle can of course also be operated, to feed in the trap 3. The bar remains unchanged in the retracted position. By the bias spring 29, the trap with the door closed in the Closing plate arranged latch opening 46 pressed. Here the door is centered relative to the door frame. An abutment 47 below the trap opening 46 provides that the position sensor 6 is no longer complete can be extended together with the trap. This relative shift between trap and position sensor leads to a rotation of the double lever 13 and thus to influence of the actuating element 14. The locking rod 10 is thereby by the movement of the locking plate in its opening freed and the bias spring 5, the push rod in Press arrow direction f down. About the management backdrop 9 is evidently the bolt 4 in the direction of the arrow g extended. The bolt penetrates with one the corresponding safety standards prescribed penetration depth of, for example, 15 mm in the bolt opening 51. The same process also takes place on the via the coupling rod 17 controlled secondary locks instead.

Der Positionsfühler 6 hat an seinem aus dem Türstulp 22 ragenden Ende eine entsprechend angeschrägte oder abgerundete Konfiguration, damit er beim Schliessen der Türe nicht am Schliessblech ansteht. Alternativ könnte natürlich auch das Widerlager 47 rampenartig ausgebildet sein.The position sensor 6 has on its out of the door cuff 22nd protruding end a correspondingly beveled or rounded Configuration so that it does not Strike plate pending. Alternatively, of course, that could also be Abutment 47 may be ramp-like.

Figur 6 zeigt die Gesamtansicht einer Türe 65 mit einem Türschloss 1 gemäss Erfindung. Das Schloss ist über die bereits erwähnten Kupplungsstangen mit einem oberen Nebenschloss 18a und mit einem unteren Nebenschloss 18b verbunden. Die Riegel dieser Schlösser dringen in ein Schliessblech, das am Türrahmen 66 befestigt ist. Wenigstens auf einer Seite der Türe ist ein Türdrücker 69 und ein Zylinderschloss 26 angeordnet.Figure 6 shows the overall view of a door 65 with a Door lock 1 according to the invention. The castle is over the already mentioned coupling rods with an upper secondary lock 18a and connected to a lower secondary lock 18b. The bolts of these locks penetrate a striking plate, the is attached to the door frame 66. At least on one side of the Door is a door handle 69 and a cylinder lock 26 is arranged.

Figur 7 zeigt eine vorteilhafte Befestigung des Schlossstulps 22 auf der Stirnseite der Türe. Im Bereich der Befestigungsschrauben 68 ist ein durchgehender Mittelsteg 67 angeordnet, der gegen die Stirnseite der Türe gepresst wird. Im vorliegenden Fall besteht diese Stirnseite aus einem Abdeckblech 70. Die Kupplungsstange 17 ist zweiteilig ausgebildet. Eine Manipulation an der Kupplungsstange bei geschlossener Türe ist bei dieser Konstruktion praktisch ausgeschlossen.Figure 7 shows an advantageous fastening of the lock cuff 22 on the front of the door. In the area of the fastening screws 68 a continuous central web 67 is arranged, which is pressed against the front of the door. In the present In this case, this end face consists of a cover plate 70. The coupling rod 17 is formed in two parts. A Manipulation on the coupling rod with the door closed is practically impossible with this construction.

In den Figuren 8 bis 10 ist ein alternatives Ausführungsbeispiel eines Türschlosses dargestellt, bei dem insbesondere das Entriegelungselement für die Sperrplatte eine etwas andere Funktion aufweist als beim vorhergehenden Ausführungsbeispiel. Die Betätigung des Nussschwenkhebels 7 und die Lagerung und Vorspannung der Schubstange 8 erfolgt im wesentlichen gleich wie beim vorhergehenden Ausführungsbeispiel und wird daher nicht mehr im Detail beschrieben. Gleiche Bauteile mit gleicher Funktion haben die gleichen Bezugszeichen wie bei den Figuren 1 bis 4.An alternative embodiment is shown in FIGS shown a door lock, in particular the unlocking element for the locking plate a little has a different function than in the previous embodiment. The actuation of the nut pivot lever 7 and the Storage and preload of the push rod 8 takes place essentially same as in the previous embodiment and is therefore no longer described in detail. Same components with the same function have the same reference numerals as in Figures 1 to 4.

Der Positionsfühler 6 ist beim vorliegenden Ausführungsbeispiel vollständig von der Falle 3 entkoppelt. Dies ermöglicht eine differenziertere Ansteuerung des Entriegelungselements zum Lösen der Sperrplatte 12. Das Entriegelungselement ist ausserdem mit einem Kraftspeicher gekoppelt, der durch die Schwenkbewegung des Nussschwenkhebels 7 aufgeladen wird. Zu diesem Zweck ist das Entriegelungselement als Doppelhebel 53 ausgebildet, der schwenkbar am Schlossgehäuse gelagert ist und der ein Hebelunterteil 54 und ein Hebeloberteil 55 aufweist. Das Hebeloberteil 55 liegt im Kippbereich der Sperrplatte 12. Der Doppelhebel 53 ist über eine Spannfeder 56, die auf der Schwenkachse angeordnet ist, in Drehrichtung gegen die Sperrplatte hin vorgespannt.The position sensor 6 is in the present embodiment completely decoupled from the trap 3. this makes possible a more differentiated control of the unlocking element to release the locking plate 12. The unlocking element is also coupled with an energy store, which by the Pivotal movement of the nut pivot lever 7 is charged. To for this purpose the unlocking element is a double lever 53 trained, which is pivotally mounted on the lock housing and the one lower lever part 54 and one upper lever part 55 having. The upper lever part 55 lies in the tilting range of the Locking plate 12. The double lever 53 is via a tension spring 56, which is arranged on the pivot axis, in the direction of rotation biased against the locking plate.

Das Hebelunterteil 54 liegt im Schwenkbereich des Hebeloberteils 39 am Nussschwenkhebel 7. Eine Drehbewegung des Nussschwenkhebels bewirkt somit nicht nur ein Zurückziehen der Falle 3 und ein Anheben der Schubstange 8, sondern auch ein Drehen des Doppelhebels 53 gegen die Kraft der Spannfeder 56.The lower lever part 54 lies in the pivoting range of the upper lever part 39 on the nut pivot lever 7. A rotary movement of the Nut pivoting lever does not only cause a retraction the trap 3 and a lifting of the push rod 8, but also rotating the double lever 53 against the force of the tension spring 56.

Neben dem Doppelhebel 53 ist eine Sperrklinke 57 schwenkbar gelagert, die auf einer Seite einen Bügel 63 aufweist. In eingerasteter Position greift der Bügel 63 über das Hebeloberteil 55 des Doppelhebels 53. Die Sperrklinke ist vorzugsweise mit Hilfe einer Feder in die Verriegelungsposition vorgespannt.In addition to the double lever 53, a pawl 57 is pivotable stored, which has a bracket 63 on one side. In in the locked position, the bracket 63 engages over the lever upper part 55 of the double lever 53. The pawl is preferred biased into the locking position by means of a spring.

An der Falle 3 ist ein Steuerhebel 58 gelenkig gelagert, der ebenfalls ein Hebelunterteil 59 und ein Hebeloberteil 60 aufweist. Das Hebeloberteil 60 ist dabei so ausgebildet, dass es in jeder Betriebslage der Falle mit der Sperrklinke 57 in Wirkverbindung steht und diese steuert.On the trap 3, a control lever 58 is articulated, the also a lower lever part 59 and an upper lever part 60 having. The upper lever part 60 is designed such that the trap with the pawl 57 in Active connection is established and controls it.

Der Positionsfühler 6, der anhand von Figur 11 erläutert wird, weist ein Mitnehmerelement 61 auf, das an einer Mitnehmerkante 64 der Falle anliegt und von dieser beim Zurückziehen der Falle angeschoben wird. Der Positionsfühler hat aber auch eine Steuerkurve 62, auf welcher das Hebelunterteil 59 des Steuerhebels 58 läuft. Das Mitnehmerelement 61 und die Steuerkurve 62 sind an einem aufrecht stehenden, plattenartigen Element angeordnet, das einen Führungsschlitz 74 aufweist. An diesem Führungsschlitz ist der ganze Positionsfühler 6 gelagert, indem ein fest am Schlosskasten angeordneter Gelenk-und Führungsdorn 75 in den Führungsschlitz eindringt. Im Schlossstulp 22 ist der Positionsfühler 6 lose gehalten. Der Positionsfühler hat somit eine Art Zweipunktelagerung. Eine Druckfeder 73 sorgt dafür, dass der Positionsfühler 6 stets gegen aussen vorgespannt ist.The position sensor 6, which is explained with reference to FIG. 11 has a driver element 61, which on a driver edge 64 the trap is present and of this when withdrawing the trap is pushed. The position sensor has but also a cam 62 on which the lower lever part 59 of the control lever 58 runs. The driver element 61 and the Control cam 62 are on an upright, plate-like Arranged element having a guide slot 74 having. The entire position sensor is at this guide slot 6 stored by a fixed on the lock case Joint and guide mandrel 75 in the guide slot penetrates. The position sensor 6 is loose in the lock face plate 22 held. The position sensor thus has a kind of two-point bearing. A compression spring 73 ensures that the position sensor 6 is always biased towards the outside.

Am Gelenk- und Führungsdorn 75 ist aber auch noch ein Sperrelement 72 in der Form eines Hebels gelenkig gelagert. Dieses Sperrelement liegt in Figur 11 hinter dem Positionsfühler. Das Sperrelement ist auf der Abbildung mittels einer Feder im Gegenuhrzeigersinn vorgespannt, so dass es in eine Ausnehmung 71 im Positionsfühler 6 eingreifen kann. Das Sperrelement 72 weist ausserdem einen Hebel 76 auf, der auf der gleichen vertikalen Ebene liegt, wie eine Kulisse 77 an der Falle 3. Beim Einziehen der Falle wird somit zunächst der Hebel 76 im Uhrzeigersinn geschwenkt und dadurch das Sperrelement 72 aus der Ausnehmung 71 herausgehoben. Erst dann beginnt das Zurückschieben des Positionsfühlers durch die Falle. Je nach der Relativlage zwischen der Falle 3 und dem Positionsfühler 6 beeinflusst der Steuerhebel 58 die Sperrklinke 57 auf die nachstehend beschriebene Art und Weise.On the hinge and guide pin 75 is also a locking element 72 articulated in the form of a lever. This The locking element is located in Figure 11 behind the position sensor. The locking element is in the picture by means of a spring in the Biased counterclockwise so that it is in a recess 71 can engage in position sensor 6. The blocking element 72 also has a lever 76 on the same vertical plane lies like a backdrop 77 on the trap 3. When the trap is pulled in, the lever 76 is thus first Pivoted clockwise and thereby the locking element 72 from the recess 71 lifted out. Only then does it start Push the position sensor back through the trap. Depending on the relative position between the trap 3 and the position sensor 6, the control lever 58 affects the pawl 57 on the way described below.

In der Position gemäss Figur 8 sind Falle 3, Positionsfühler 6 und Riegel 4 voll ausgefahren. Diese Situation tritt ein, wenn beispielsweise bei geöffneter Türe der Riegelantrieb betätigt wird. Die Vorspannfeder 29 drückt die Falle 3 ganz nach Aussen und der Doppelhebel 53 hält die Sperrplatte 12 in der Lösestellung. Die Sperrklinke 57 wird durch den Steuerhebel 58 in der Oeffnungsposition gehalten.In the position according to FIG. 8 there are trap 3, position sensors 6 and latch 4 fully extended. This situation occurs if, for example, the bolt drive with the door open is operated. The biasing spring 29 presses the latch 3 completely outwards and the double lever 53 holds the locking plate 12 in the release position. The pawl 57 is operated by the control lever 58 held in the open position.

Bei der Position gemäss Figur 9 sind Falle 3, Positionsfühler 6 und Riegel 4 gerade soweit zurückgezogen, dass sie das Schliessblech 23 verlassen und dass die Türe unter Druck geöffnet werden kann. Der Nussschwenkhebel 7 hat dabei den Doppelhebel 53 gegen die Kraft des Kraftspeichers vorgespannt, so dass die Sperrplatte 12 den Sperrstab 10 sofort arretiert, wenn sich dieser nach unten bewegt. Gleichzeitig schiebt sich der Bügel 63 der Sperrklinke über das Hebeloberteil 55 des Doppelhebels 53, so dass dieser in der gespannten Lage arretiert wird. In the position according to FIG. 9, trap 3 are position sensors 6 and bolt 4 withdrawn just so far that they Strike plate 23 and leave the door under pressure can be opened. The nut pivot lever 7 has the Double lever 53 biased against the force of the energy accumulator, so the locking plate 12 the locking rod 10 immediately locked when it moves down. At the same time the bracket 63 of the pawl slides over the upper lever part 55 of the double lever 53, so that this in the tensioned position is locked.

Nach dem Oeffnen der Türe und nach dem Loslassen des Türdrückers bleibt der Riegel 4 in einer ganz oder teilweise zurückgezogenen Position. Dagegen wird die Falle 3 unter der Vorspannkraft der Feder 29 wieder ganz nach aussen gedrückt. Ebenso der Positionsfühler 6, der unter der Vorspannkraft der Feder 73 steht. Dabei rastet das Sperrelement 72 wiederum in die Ausnehmung 71 ein und der Positionsfühler 6 bleibt arretiert. Ein unbeabsichtigtes Auslösen des Riegelantriebs durch Manipulation am Positionsfühler ist bei geöffneter Türe somit nicht möglich. Ein Eindrücken der Falle bleibt ebenfalls wirkungslos, da nur die Relativstellung "ausgefahrene Falle / eingedrückter Fühler" den Riegelantrieb auslösen kann.After opening the door and releasing the lever handle the latch 4 remains in one or all of it retracted position. In contrast, the trap 3 under the Preload force of the spring 29 is pushed all the way out again. Likewise, the position sensor 6, which is under the biasing force of the Spring 73 stands. The locking element 72 snaps in again the recess 71 and the position sensor 6 remains locked. An unintentional triggering of the bolt drive by manipulating the position sensor when the door is open therefore not possible. Pressing in the trap also remains ineffective, since only the relative position "extended Latch / depressed sensor "trigger the bolt drive can.

In der Position gemäss Figur 10 ist die Falle 3 bereits wieder teilweise in das Schliessblech ausgefahren, so dass das Schloss zentriert ist. Der Positionsfühler 6 bleibt jedoch am Schliessblech, wobei der Steuerhebel 58 an der Steuerkurve 62 nach oben gedrückt wird. Dabei wird die Sperrklinke 57 gelöst und der Doppelhebel 53 schlägt an der Sperrplatte 12 mit einer definierten Kraft an. Der Riegel 4 wird dadurch im nächsten Augenblick ausgefahren.The trap 3 is already in the position according to FIG. 10 partially extended into the striking plate so that the lock is centered. The position sensor 6 remains but on the striking plate, the control lever 58 on the Control curve 62 is pressed upwards. The pawl 57 released and the double lever 53 strikes the Locking plate 12 with a defined force. The latch 4 will be extended in the next moment.

Zur Dämpfung der Schubstange 8 beim Auslösen des Riegels 4 kann auf der Unterseite ein Dämpfungselement aus Kunststoff oder dergleichen angeordnet werden. Dadurch wird unnötiger Lärm vermieden und die Lebensdauer der Schubstange erhöht. Die Führungskulisse 9 an der Schubstange ist so ausgelegt, dass der Riegel bereits in der endgültig zurückgezogenen Position gehalten wird, während die Schubstange noch einen Restweg zurücklegt. Ueber diesen Mehrweg der Schubstange kann beispielsweise auch ein grösserer Federweg für die Vorspannfeder 5 zurückgelegt werden.To dampen the push rod 8 when the bolt 4 is released can have a plastic damping element on the underside or the like can be arranged. This will make it unnecessary Avoiding noise and increasing the lifespan of the push rod. The guide link 9 on the push rod is designed so that the bolt was already retracted in the final Is held in position while the push rod is still one Distance traveled. This reusable push rod can be used for example, a larger spring travel for the bias spring 5 can be covered.

Die Figur 12 zeigt zum besseren Verständnis eine Gegenüberstellung der Wegstrecken für die Falle 3 einerseits und für den Riegel 4 anderseits in der Form eines Blockdiagramms. Die Basis ist in beiden Fällen die Ebene des Schlossstulps. Die maximale Ausfahrstrecke des Riegels 4 kann beispielsweise 21 mm betragen. Demgegenüber beträgt die maximale Ausfahrstrecke der Falle 3 12 mm. Die Masse sind ausgelegt für eine maximal mögliche Lichte Weite zwischen Schlossstulp und Schliessblech LW max. von 7 mm und eine minimale Lichte Weite LW min. von 3 mm. Das Getriebe ist so ausgelegt, dass bei einem Fallenweg FW von 5 mm ein Riegelweg RW von 15 mm zurückgelegt wird. Dabei ist bei der Falle ein Freilauf FL von 3 mm vorgesehen, bevor das Entriegelungselement geladen ist. Der eigentliche Spannvorgang SV findet auf einer Fallenstrecke von 2 mm statt. Auf der verbleibenden Wegstrecke VW ist der Ladevorgang abgeschlossen.Figure 12 shows a comparison for better understanding the distances for the trap 3 on the one hand and for the latch 4 on the other hand in the form of a block diagram. The In both cases, the basis is the level of the lock cuff. The maximum extension distance of the bolt 4 can be 21, for example mm. In contrast, the maximum extension distance is the trap 3 12 mm. The dimensions are designed for a maximum possible clearance between lock faceplate and strike plate LW max. of 7 mm and a minimum clear width LW min. Of 3 mm. The gearbox is designed so that there is a trap path FW of 5 mm, a bolt travel RW of 15 mm is covered. A free-wheeling FL of 3 mm is provided in the case, before the unlocking element is loaded. The actual Tensioning process SV takes place on a trap path of 2 mm instead of. The charging process is on the remaining route VW completed.

A door lock (1) having a latch (3) actuable by way of a bush member (2) and having a bolt (4) which is operatively connected to the bush member in such a way that together with the latch it can be retracted against the force of a biasing spring (5) by way of a transmission which has a locking means, wherein the locking means engages a transmission member in such a way that the bolt can be arrested at least in an end portion of its retraction movement, and wherein the locking means is releasable by way of a position sensor (6) projecting out of the door lock, and the bolt (4) is extensible under the action of the biasing spring (5), wherein moreover the transmission has a bush pivot lever (7) which is connected to the bush member (2) and which engages a linearly displaceable thrust bar (8) which is acted upon by the biasing spring (5), characterised in that the locking means has a locking bar portion (10) which is arranged on the thrust bar (8) and which passes through an opening (11) in a fixed but tiltably mounted locking plate (12), wherein the locking bar portion and the locking plate can be steplessly braced relative to each other within the two end positions of the thrust bar, and that the locking plate is movable by way of an unlocking element operatively connected to the position sensor (6) from a locking position in which the locking bar portion tilts in the opening (11) into a release position in which the locking bar portion can move freely in the opening (11).
  2. A door lock according to claim 1 characterised in that the thrust bar (8) is drivingly connected to the bolt (4) by way of a sliding guide means (9).
  3. A door lock according to claim 2 characterised in that the sliding guide means (9) extends relative to the direction of movement of the bolt (4) in such a way that the transmission is self-blocking when the bolt is extended, in which case the bolt cannot be pushed in.
  4. A door lock according to one of claims 1 to 3 characterised in that the unlocking element is in the form of a double lever (13) which is mounted pivotably on the latch (3), that the one arm (40) of the double lever is connected to the positioning sensor (6), and that the other arm (41) of the double lever bears against an actuating element (41) which is connected to the locking plate (12), wherein simultaneous displacement of the latch and the positioning sensor does not cause the actuating element to be influenced while a relative movement between the latch and the positioning sensor causes a movement of the actuating element which pivots the locking plate into the release position.
  5. A door lock according to one of claims 1 to 3 characterised in that the unlocking element is connected to a stressing spring (56) which can be stressed when the latch is retracted, that the unlocking element is arrestable in a stressing position and that upon a relative displacement between the latch and the position sensor the unlocking element is releasable from the stressing position, in which case it hits against the locking plate and moves it into the release position.
  6. A door lock according to one of claims 1 to 3 characterised in that the unlocking element is in the form of a double lever (53) which is mounted pivotably, that the one arm (54) of the double lever is disposed in the region of pivotal movement of the bush pivot lever and that the other arm (55) of the double lever is in the tilting region of the locking plate (12), that the double lever is pivotable away from the locking plate against the force of a stressing spring (56) upon rotation of the bush pivot lever (7), and that arranged beside the double lever (53) is a locking pawl (57) which arrests it in the stressing position.
  7. A door lock according to claim 6 characterised in that pivotably mounted on the latch is a control lever (58) with which the locking pawl (57) is controllable, that the position sensor (6) is decoupled from the latch, in which case it is retractable together with the latch, and that upon relative displacement between the latch and the position sensor upon extension of the latch the control lever is actuated and in that situation the locking pawl (57) is releasable.
  8. A door lock according to claim 7 characterised in that the position sensor (6) has a control cam (62) co-operating with the control lever (58) in such a way that the locking pawl (57) is released only in the final phase of the extension movement of the latch.
  9. A door lock according to one of claims 1 to 8 characterised in that the bush member (2) is divided into an inner and an outer entrainment arm (15) which are rotatable independently of each other, wherein the bush pivot lever (7) is arranged between the two entrainment arms, and that disposed on each of the two sides of the bush pivot lever in the region of pivotal movement of the entrainment arms is a respective entrainment element (16) of which at least one is switchable manually by key actuation or electromagnetically by a drive element from an idle position within the region of rotary movement of the entrainment arm into an engagement position within the region of rotary movement of the entrainment arm.
  10. A door lock according to one of claims 1 to 9 characterised in that the transmission is connected by a coupling bar (17) to at least one auxiliary lock (18) which also has a bolt (45) which can be retracted against the force of a biasing spring (19).
  11. A door lock according to claim 10 characterised in that the auxiliary lock has a linearly displaceable thrust bar (21) which is connected to the coupling bar and which is connected to the bolt by way of a sliding guide (21) and that the biasing spring (19) engages the thrust bar (20).
  12. A door lock according to one of claims 10 and 11 characterised in that the coupling bar (17) is guided in a lock faceplate member (22) which is secured to the face of the door by means of screws, wherein it is supported against the face of the door in the region of the screws with a central land portion through which a screw passes, and wherein the coupling bar is of a two-part configuration in the region of the central land portion.
  13. A door having a door lock according to one of claims 1 to 12 and a door frame on which a lock striker plate is arranged, characterised in that arranged on the lock striker plate (23) beside the opening (46) for the latch (3) is a support means (47) for the positioning sensor (6) which when the latch is engaged holds the positioning sensor pressed in relative to the latch.
  14. A door lock according to claim 9 characterised in that a cylinder lock (26) and a solenoid (27) are provided for activation of the entrainment element (16) and that upon actuation of the cylinder lock a switching device can be activated which interrupts the supply of power to the solenoid.
  15. A door lock (1) having a bolt (4) which can be actuated by way of a bush member (2) and which is operatively connected to the bush member in such a way that it can be retracted against the force of a biasing spring (5) by way of a transmission which has a locking means, wherein the locking means engages a transmission member in such a way that the bolt can be arrested at least in an end portion of its retraction movement, and wherein the locking means is releasable by way of a position sensor (6) projecting out of the door lock, and the bolt (4) is extensible under the action of the biasing spring (5), wherein moreover the transmission has a bush pivot lever (7) which is connected to the bush member (2) and which engages a linearly displaceable thrust bar (8) which is acted upon by the biasing spring (5), characterised in that the locking means has a locking bar portion (10) which is arranged on the thrust bar (8) and which passes through an opening (11) in a fixed but tiltably mounted locking plate (12), wherein the locking bar portion and the locking plate can be steplessly braced relative to each other within the two end positions of the thrust bar, and that the locking plate is movable by way of an unlocking element operatively connected to the position sensor (6) from a locking position in which the locking bar portion tilts in the opening (11) into a release position in which the locking bar portion can move freely in the opening (11).
