Abstract

A mortice lock possesses, to protect it against the lock latch (3) being pushed back by a tool, especially break-in tool, engaging on the latter, a control latch (12) which is located opposite the lock plate (10) and which is pressed back by this when the door is closed. The push-in movement is transmitted by means of a corner deflection to a bolt (14) which is located inside the lock case (1) and which can be pushed into the path of the lock latch (3) at a distance from a stop face of the latter. The lock latch (3) subsequently cannot be manipulated by direct attack from outside. The follower (5) engages on a lever (18) which engages into the bolt (14) and which, with the door closed, pulls the latter back, as a result of the actuation of the handle, out of the path of the lock latch (3) in order to release the latter. A changer (6) is connected to the locking mechanism, for example lock cylinder (7), and likewise engages on the lever (18). <IMAGE>

Description

Die Erfindung betrifft ein Einstemmschloß mit Stulp, Schloßgehäuse und mit einer in eine Schließblechtasche einrastbaren Schloßfalle, die gegen die Kraft einer Feder zurückschiebbar und mittels einer Nuß durch einen Drücker od.dgl. sowie gegebenenfalls mittels eines Wechsels von einem Riegelgesperre, z.B. einem Schließzylinder, betätigbar ist, sowie mit einer gegen Federkraft einschiebbare und im Stulp geführten Steuerfalle zur Blockierung der Schloßfalle gegen ein Zurückdrücken von außen etwa durch Einschieben eines Plättchens in den Türspalt.The invention relates to a mortise lock with faceplate, lock housing and with a lock latch which can be snapped into a striking plate pocket and which can be pushed back against the force of a spring and by means of a nut or the like by means of a pusher. and optionally by changing from a locking bar, e.g. a lock cylinder which can be actuated, and with a control latch which can be inserted against spring force and which is guided in the faceplate to block the lock latch against pushing back from the outside, for example by inserting a small plate into the door gap.

Bei Türen, die außen an Stelle eines Drückers über einen drehfesten Griff oder Knopf verfügen, wobei die Schloßfalle nur mit Hilfe des passenden Schlüssels zurückgezogen werden kann,sind Einbruchsmethoden mit Hilfe eines Kunststoffkärtchens bekannt.Dieses wird in den Türspalt dort eingeschoben, wo sich die Falle befindet. Das Kunststoffkärtchen, etwa eine Creditcard, ist einerseits elastisch genug, um sich dem Türfalz anzupassen und diesen zu überwinden und anderseits fest genug, um beim Auflaufen auf die Schägfläche der Schloßfalle diese zuzurückzudrücken. Auf diese Weise konnten unversperrte Türen mit Schlössern der eingangs genannten Art rasch und unauffällig geöffnet werden. Versuche, auf der Schrägfläche der Schloßfalle V-förmige Nuten anzuordnen, um das elastische Kärtchen beim Andrücken an die Schrägfläche der Falle zu fangen und dadurch ein weiteres Zurückschieben der Schloßfalle zu verhindern, haben zu keinen überzeugenden Ergebnissen geführt.For doors that have a non-rotatable handle or knob instead of a handle, and the lock latch can only be withdrawn with the appropriate key, burglary methods using a plastic card are known, which are inserted into the door gap where the latch is located. The plastic card, such as a credit card, is on the one hand elastic enough to adapt to and overcome the door rebate, and on the other hand firm enough to push it back onto the inclined surface of the lock latch. In this way, unlocked doors with locks of the type mentioned above could be opened quickly and unobtrusively. Attempts to arrange V-shaped grooves on the inclined surface of the lock latch in order to catch the elastic card when pressed against the inclined surface of the latch and thereby prevent the lock latch from being pushed back further have not led to convincing results.

Aus der DE-OS 34 47 748 ist es bekannt, zur Blockierung der in ein Schließblech eingreifenden Schloßfalle und damit zur Verhinderung der vorgenannten Einbruchsmethoden, eine zusätzliche Steuerfalle im Schloß vorzusehen. Die Steuerfalle ist bei geschlossener Tür mangels einer korrespondierenden Ausnehmung im Schließblech in das Schloß zurückgeschoben und greift über Steuerelemente und Hebel an einen Anschlag am Fallenschaft an. Da die erforderlichen Bauteile unmittelbar im Bereich der funktionswichtigen Kinematik des Schlosses liegen, ist die konkrete Ausbildung in der Praxis auch hinsichtlich der Montage kompliziert und es sind gegenseitige Beeinflussungen der übereinander liegenden Funktionselemente nicht auszuschließen.From DE-OS 34 47 748 it is known to provide an additional control latch in the lock to block the lock latch engaging in a strike plate and thus to prevent the above-mentioned break-in methods. When the door is closed, the control latch is pushed back into the lock due to the lack of a corresponding recess in the striking plate and engages a stop on the drop shaft via controls and levers. Since the required components are located directly in the area of the lock's kinematics, which is important for the function, the specific training in practice is also complicated with regard to assembly and mutual influences of the functional elements lying one above the other cannot be ruled out.

Die Erfindung zielt darauf ab, die Bauweise der Fallenblockierung zu vereinfachen, von der übrigen Schloßmechanik zu trennen und damit eine einfache Montage und einen störungsfreien Betrieb zu gewährleisten. Dies wird dadurch erreicht, daß ein an der Steuerfalle kinematisch angelenkter und etwa senkrecht zur Steuerfallenführung längs des Stulpes oder parallel zu diesem geführter Riegel in der eingeschobenen Stellung der Steuerfalle unmittelbar in die Schloßfalle bzw. in deren Führungsbahn mit einem Abstand zu einer Anschlagfläche der Schloßfalle einrückbar ist und daß mit der Nuß mindestens ein Hebel verbunden ist, dessen freies Ende an dem Riegel zu dessen Zurückziehen bei Drückerbetätigung angreift. Die Verriegelung kann bei geschlossener Tür nur durch den Drücker von innen oder durch den passenden Schlüssel über den Wechsel aufgehoben werden. Wird von außen mittels eines Einbruchswerkzeuges, wie etwa die einleitend genannte elastische Kunststoffkarte, auf die Schrägfläche der Schloßfalle eingewirkt, dann kann die Schloßfalle nur ein geringes Stück bis zum Anschlag an den Riegel zurückgeschoben werden. Die Wirkung der Schloßfalle als zuverlässiges Sperrelement bleibt zur Gänze erhalten. Die Führung des Riegels etwa längs des Stulpes und der dadurch rechtwinkelige Angriff des Riegels unmittelbar an der Schloßfalle sind Merkmale, die die Funktionssicherheit im besonderen Maße gewährleisten. Zudem kann die Entriegelung bei Drückerbetätigung besonders einfach durch einen die Nuß mit dem Riegel verbindenden Hebel gelöst werden. Es ist zweckmäßig, wenn der Steuerfallenschaft eine schräge Auflauffläche aufweist, an der ein Mitnehmer unter Federkraft anliegt. Der Mitnehmer ist ein Teil des Riegels, der in einer etwa im rechten Winkel zur Steuerfallenführung vorgesehenen Riegelführung verschiebbar gelagert ist. Auf diese Weise erfolgt eine Kraftumlenkung von der horizontalen Bewegungsrichtung der Steuerfalle zur vertikalen Bewegungsrichtung der Schloßfallenverriegelung. Zur Entriegelung der Schloßfalle weist die Nuß einen Ansatz auf, der mit dem Kraftarm des zweiarmigen Hebels verbunden ist, dessen Lastarm an den Riegel angreift. Infolge des Abstandes zwischen der Schloßfallenanschlagfläche und dem Riegel für die Schloßfalle kann der Drücker oder Drehknopf etwas bewegt werden. Dadurch wird die Nuß um einen kleinen Winkel verdreht, bis die Schloßfalle an den Riegel ansteht. Diese Drehbewegung der Nuß wird über den zweiarmigen Hebel mit entsprechender Übersetzung auf den Riegel übertragen, der dadurch aus der Bahn der Schloßfalle zurückgezogen wird und ein Weiterdrehen der Nuß somit ermöglicht. Die Schloßfalle kann wie üblich auch bei geschlossener Tür zurückgezogen werden, dies allerdings nur durch den Drücker oder über den Wechsel mittels des Gesperres. Dazu ist mit dem Kraftarm das eine Ende eines Wechsels, beispielsweise eine Schubstange oder Platte, kinematisch verbunden und dessen anderes Ende vom Riegelgesperre, insbesondere einem Schließzylinder und den Zuhaltungen betätigbar. Der Wechsel führt jene Bewegung aus, die auch über den Drückerund die Nuß einleitbar ist.The invention aims to simplify the construction of the latch lock, to separate it from the rest of the lock mechanism and thus to ensure simple assembly and trouble-free operation. This is achieved in that a kinematically articulated to the control latch and approximately perpendicular to the control latch guide along the faceplate or parallel to this bolt in the inserted position of the control latch can be directly engaged in the lock latch or in its guideway at a distance from a stop surface of the lock latch and that at least one lever is connected to the nut, the free end of which engages on the bolt to retract it when the handle is actuated. When the door is closed, the lock can only be released by pressing the button on the inside or by using the appropriate key. If an intrusion tool, such as the elastic plastic card mentioned in the introduction, acts on the inclined surface of the lock latch, the lock latch can only be pushed back a little bit until it stops. The effect of the lock latch as a reliable locking element remains intact. The guidance of the bolt approximately along the faceplate and the consequent right-angled attack of the bolt directly on the lock latch are features that guarantee the functional reliability to a particular degree. In addition, the release can be released particularly easily when the handle is actuated by a lever connecting the nut to the bolt. It is expedient if the control case shaft has an oblique run-up surface against which a driver rests under spring force. The driver is part of the bolt which is slidably mounted in a bolt guide provided approximately at right angles to the control latch guide. In this way, a force is diverted from the horizontal direction of movement of the control latch to the vertical direction of movement of the lock latch locking. To unlock the lock latch, the nut has an extension which is connected to the power arm of the two-armed lever, the load arm of which engages the bolt. Due to the distance between the lock latch stop surface and the bolt for the lock latch the pusher or rotary knob can be moved slightly. As a result, the nut is rotated through a small angle until the lock latch is in contact with the bolt. This rotary movement of the nut is transmitted via the two-armed lever with appropriate translation to the bolt, which is thereby withdrawn from the path of the lock latch and thus allows the nut to be turned further. As usual, the lock latch can also be pulled back when the door is closed, but only with the handle or by changing the locking mechanism. For this purpose, one end of a change, for example a push rod or plate, is kinematically connected to the power arm and the other end can be actuated by the locking mechanism, in particular a locking cylinder and the tumblers. The change carries out the movement that can also be initiated via the handle and the nut.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in derZeichnung dargestellt. Die Figur zeigt die Ansicht eines Einstemmschlosses bei abgenommener Schloßdecke. Für das Verständnis der Erfindung unwesentliche Teile wurden in der Zeichnung weggelassen. Dargstellt ist das Einstemmschloß bei offener Tür. Ein Schließblech ist dem Stulp gegenüber strichliert angedeutet.An embodiment of the subject of the invention is shown in the drawing. The figure shows the view of a mortise lock with the lock cover removed. Parts that are insignificant for understanding the invention have been omitted from the drawing. The mortise lock is shown with the door open. A striking plate is indicated by dashed lines opposite the faceplate.

In ein Schloßgehäuse 1 mit Stulp 2 ist eine Schloßfalle 3 gegen die Kraft einer Feder 4 einschiebbar. Die Schloßfalle 3 kann auch durch einen nicht dargestellten Drücker mittels einer Nuß 5 in bekannter Weise betätigt werden. Schließlich ist ein Wechsel 6 vorgesehen, der die Schloßfallenbetätigung mittels eines Schlüssels über einen Schloßzylinder 7 und ein Riegelgesperre 8 ermöglicht.In a lock housing 1 with faceplate 2, a lock latch 3 can be inserted against the force of a spring 4. The lock latch 3 can also be actuated in a known manner by a handle (not shown) by means of a nut 5. Finally, a change 6 is provided, which enables the lock latch actuation by means of a key via a lock cylinder 7 and a locking mechanism 8.

Bei geschlossener Tür greift die Schloßfalle 3 in eine Schließblechtasche 9 eines bloß mit strichlierten Linien angedeuteten Schließbleches 10 in einem Türstock ein. Durch den Türspalt hindurch könnte es mittels eines flexiblen Federplätchens, einem Kartonstreifen oder einer Kunststoffkarte (z.B. Creditkarte) gelingen, die Falle zurückzudrücken. Stößt nämlich das vorgenannte "Werkzeug" auf die Einlaufschräge der Schloßfalle, dann weicht diese bei fortgesetztem Druck zurück, bis sie hinter dem Stulp 2 verschwindet. Wenn das Einstemmschloß nicht gesperrt ist, sich also der Schloßriegel 11 in der dargestellten Position befindet, dann kann eine Tür mit starrem, äußerem Drücker oder Griff auf diese Weise geöffnet werden. Um die Schließfalle in geschlossenem Zustand der Tür so zu verriegeln, daß sie nicht durch äußere Einwirkung, sondern nur über den innen befindlichen Drücker oder mittels des passenden Schlüssels über den Wechsel von außen geöffnet werden kann, ist folgende Konstruktion vorgesehen:
   Eine Steuerfalle 12 ist im Stulp 2 unterhalb der Schloßfalle 3 gelagert. Der Steuerfalle 12 liegt keine Schließblechtasche, gegenüber; das Schließblech 10 ist von der handelsüblichen Art. Bei geschlossener Tür wird daher die Steuerfalle 12 durch Auflaufen auf das Schließblech in das Schloßgehäuse hineingedrückt. Der Steuerfallenschaft weist eine schräge Auflauffläche 13 auf, an der ein von einem Riegel 14 vorspringender Mitnehmer 15 unter der Kraft einer Feder 16 anliegt. Der Riegel 14 ist an seinen beiden Enden geführt. Wird nun die Steuerfalle 12 gegen die Kraft einer Blattfeder 17 beim Schließen einer Tür zurückgedrückt, dann gleitet der Mitnehmer 15 längs der Auflauffläche 13 und somit der Riegel 14 nach oben,weil sich die andrückende Feder 16 entspannen kann. Der Riegel 14 ragt damit in die Bewegungsbahn der Schloßfalle 3, wie dies strichliert mit 14′ dargestellt ist. Wird in der geschlossenen Stellung der Tür nun versucht, die Schloßfalle 3 von außen zurückzudrücken läuft sie nach kurzem Weg gegen den Riegel 14′, der ein weiteres Zurückdrücken verhindert.When the door is closed, the lock latch 3 engages in a strike plate pocket 9 of a strike plate 10, which is merely indicated by dashed lines, in a door frame. A flexible spring plate, a cardboard strip or a plastic card (e.g. credit card) could push the trap back through the gap in the door. If the above-mentioned "tool" comes into contact with the slant of the lock latch, it will recede with continued pressure until it disappears behind the faceplate 2. If the mortise lock is not locked is, that is, the lock bolt 11 is in the position shown, then a door with a rigid, external handle or handle can be opened in this way. In order to lock the locking latch in the closed state of the door so that it cannot be opened from the outside by external action, but only by means of the inside handle or by means of the appropriate key, the following construction is provided:
A control latch 12 is mounted in the faceplate 2 below the lock latch 3. The control latch 12 is not opposite a striking plate pocket; the striking plate 10 is of the commercially available type. When the door is closed, the control latch 12 is therefore pressed into the lock housing by running onto the striking plate. The control case shaft has an inclined run-up surface 13 against which a driver 15 projecting from a bolt 14 rests under the force of a spring 16. The bolt 14 is guided at both ends. If the control latch 12 is pressed back against the force of a leaf spring 17 when a door is closed, then the driver 15 slides along the run-up surface 13 and thus the bolt 14 upwards because the pressing spring 16 can relax. The bolt 14 thus protrudes into the path of movement of the lock latch 3, as shown in dashed lines with 14 '. Is now in the closed position of the door trying to push the lock latch 3 back from the outside, it runs after a short distance against the bolt 14 ', which prevents further pushing back.

Die Wirkung des Riegels 14 in seiner Position 14′ muß aber aufgehoben werden, wenn die Schloßfalle befugterweise mittels des Drückers von innen oder über den Wechsel 6 von außen durch einen passenden Schlüssel betätigt werden soll. Dazu ist ein mittig oder außermittig gelagerter, zweiarmiger Hebel 18 mit seinem Kraftarm mit einem Ansatz 19 der Nuß 5 gelenkig verbunden und greift mit seinem Lastarm an dem Riegel 14 an. Wird nun der Drücker betätigt, dann kann die Nuß 5 jedenfalls um einen kleinen Winkel gedreht werden, bis die Schloßfalle 3 an dem Riegel 14′ ansteht. Diese Drehbewegung der Nuß 5 wird somit über den Ansatz 19 und den zweiarmigen Hebel 18 als Linearbewegung auf den Riegel 14 übertragen, der aus seiner vorgeschobenen Stellung 14′ in die mit vollen Linien gezeichnete Stellung zurückgezogen wird. In dieser Riegelstellung (14) wird die Schloßfalle 3 in ihrer Rückzugsbewegung nichtmehr behindert. Die Schloßfalle 3 kann also infolge des Abstandes zwischen Falle 3 und Riegel 14′, der eine Bewegung des Drückers und damit der Hebelverbindungen bis zum Riegel 14 erlaubt, mit Hilfe des Drückers wie bei einem üblichen Einstemmschloß betätigt werden. Aber auch mittels eines Schlüssels kann der Riegel 14 aus der Stellung 14′ zurückgezogen werden, weil der Wechsel 6, der bei Schlüsselbetätigung hochgeschoben wird, ebenfalls den zweiarmigen Hebel 18 verdreht, sodaß sein Lastarm in der Zeichnung nach unten drückt und den Riegel 14 damit aus der Stellung 14′ zurückzïeht. Beim Weiterdrehen des Schlüssels wird so wie beim weiteren Betätigen des Drückers die Schloßfalle 3 zur Gänze über den Verriegelungspunkt hinaus zurückgezogen.The effect of the bolt 14 in its position 14 'must be canceled if the lock latch is to be actuated by means of the handle from the inside or via the change 6 from the outside by a suitable key. For this purpose, a centrally or eccentrically mounted, two-armed lever 18 is articulated with its power arm with an extension 19 of the nut 5 and engages with the load arm on the bolt 14. If the handle is now operated, the nut 5 can in any case be rotated by a small angle until the lock latch 3 is present on the bolt 14 '. This rotary movement of the nut 5 is thus transmitted via the extension 19 and the two-armed lever 18 as a linear movement to the bolt 14, which is withdrawn from its advanced position 14 'into the position drawn with full lines becomes. In this locking position (14), the lock latch 3 is no longer hindered in its retraction movement. The lock latch 3 can thus be operated with the help of the handle as in a conventional mortise lock due to the distance between the latch 3 and bolt 14 ', which allows movement of the handle and thus the lever connections to the latch 14. But also by means of a key, the bolt 14 can be withdrawn from the position 14 'because the change 6, which is pushed up when the key is actuated, also rotates the two-armed lever 18, so that its load arm presses downwards in the drawing and the bolt 14 is thus removed the position 14 'retires. When the key is turned further, the lock latch 3 is completely withdrawn beyond the locking point, as is the case when the handle is pressed further.
