Description

Die vorliegende Erfindung betrifft ein Türschloss zum Einbau in ein Einschubfach eines Türblatts einer Türe gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a door lock for installation in an insertion compartment of a door leaf of a door according to the preamble of patent claim 1.

Derartige Türschlösser sind aus dem Stand der Technik bekannt und im Allgemeinen so aufgebaut, dass das Türschloss in ein Einschubfach eines Türblattes einer Türe, das an der schmalen Längsseite des Türblattes angeordnet ist, einschiebbar und dort fixierbar ist. Ein derartiges Türschloss ist in der Regel mit einem Riegel ausgestattet, der über ein an einer Vorderseite des Türschlosses angeordnetes Bedienelement betätigbar ist. Auf diese Weise kann das Türschloss in einem geschlossenen Zustand der Türe mittels des Riegels zum Verschließen der Türe eingesetzt werden. Der Riegel kann entweder für eine Schwenktüre linear aufgebaut sein oder, wenn das Türschloss für Schiebetüren eingesetzt wird, in Form einer nach unten oder nach oben gebogenen Verriegelungsnase ausgestaltet sein, sodass die Schiebetüre durch einen hakenförmig nach unten bzw. nach oben reichenden Abschnitt des Riegels verschlossen gehalten wird.Such door locks are known from the prior art and generally constructed so that the door lock can be inserted and fixed in an insertion compartment of a door leaf of a door, which is arranged on the narrow longitudinal side of the door leaf. Such a door lock is generally equipped with a latch which can be actuated via a control element arranged on a front side of the door lock. In this way, the door lock can be used in a closed state of the door by means of the bolt for closing the door. The bolt can either be linearly constructed for a swing gate or, if the door lock is used for sliding doors, be designed in the form of a downwardly or upwardly bent locking lug, so that the sliding door closed by a hook-shaped downwardly or upwardly reaching portion of the bolt is held.

Derartige Türschlösser werden bspw. zum Verschließen von Toilettentüren im Bereich des Flugzeugbaus eingesetzt.Such door locks are used, for example, for closing toilet doors in the field of aircraft construction.

Um die Türschlösser in dem Einschubfach des Türblattes montieren zu können, ist es notwendig, das Bedienelement, wenn dieses bspw. erhaben sein soll, um eine bessere Handhabbarkeit zu erreichen, für den Einbau des Türschlosses von diesem demontierbar ist.In order to mount the door locks in the slot of the door leaf, it is necessary, the control element, if this example. To be raised in order to achieve better handling, for the installation of the door lock of this is removable.

Bisher wird dies so gelöst, dass bspw. das Bedienelement ein Schraubgewinde aufweist, das in eine entsprechend angeordnete Bohrung des Türschlosses eingeschraubt werden kann. Eine solche Ausgestaltung hat den Nachteil, dass derartige Bedienelemente durch ein Drehen des Bedienelementes entfernt werden können und so aufgrund von Diebstahl oder Vandalismus häufig ersetzt werden müssen. Darüber hinaus weisen einschraubbar ausgestaltete Bedienelemente den Nachteil auf, dass sie nicht formschlüssig in einer Führung des Türschlosses anordenbar sind.So far, this is solved so that, for example, the control element has a screw thread which can be screwed into a correspondingly arranged bore of the door lock. Such an embodiment has the disadvantage that such controls can be removed by turning the control and so often have to be replaced due to theft or vandalism. In addition, screw-designed controls have the disadvantage that they are not form-fitting manner in a guide of the door lock can be arranged.

Für den Fall, dass das Bedienelement formschlüssig in einer Führung des Türschlosses angeordnet werden soll, ist es bislang bekannt, solche Bedienelemente, die bspw. als Schieber ausgestaltet sein können, über eine Rastverbindung mit dem eingebauten Türschloss zu verbinden. Bedienelemente, die über Rastverbindungen an dem Türschloss befestigt sind, weisen jedoch den Nachteil auf, dass sie in der Regel nicht ohne Weiteres zu Servicezwecken demontierbar sind und darüber hinaus solche Rastverbindungen, wenn diese bspw. aus Kunststoff gefertigt sind, durch Ermüdung des Kunststoffes kaputt gehen können. Darüber hinaus kann ein entsprechend mit einer Rastverbindung angeordnetes Bedienelement mit einem erhöhten Kraftaufwand oder einem Hebelwerkzeug ebenso entfernt werden, sodass auch hier die Gefahr von Vandalismus besteht.In the event that the control element is to be arranged in a form-fitting manner in a guide of the door lock, it has hitherto been known to connect such control elements which, for example, can be configured as a slide, via a latching connection with the built-in door lock. However, controls that are attached via snap-in connections to the door lock, however, have the disadvantage that they are usually not readily disassembled for service purposes and beyond such locking connections, if these are made, for example. Plastic, go through fatigue of the plastic broken can. In addition, a correspondingly arranged with a locking connection control with an increased force or a lever tool can also be removed, so that there is a risk of vandalism here.

Es ist die Aufgabe der vorliegenden Erfindung, ein bekanntes Türschloss derart weiterzubilden, dass die oben genannten Nachteile vermieden werden und gleichzeitig eine zuverlässige und günstig herzustellende Befestigung für das Bedienelement geschaffen wird.It is the object of the present invention to develop a known door lock in such a way that the above-mentioned disadvantages are avoided and at the same time a reliable and inexpensive to produce attachment for the control is created.

Diese Aufgabe wird durch ein Türschloss mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a door lock with the features of claim 1.

Ein erfindungsgemäßes Türschloss zum Einbau in ein Einschubfach eines Türblattes einer Türe weist einen Riegel auf, der über ein an einer Vorderseite des Türschlosses angeordnetes Bedienelement betätigbar ist, wobei das Bedienelement von einer Rückseite des Türschlosses her befestigbar ist und zur Verdeckung eines Befestigungselementes eine verschiebbare Blende vorgesehen ist.An inventive door lock for installation in a drawer of a door leaf of a door has a latch which is operable via a arranged on a front of the door lock control, the control element from a back of the door lock can be fastened forth and provided to cover a fastener a sliding panel is.

Dadurch, dass das Bedienelement von der Rückseite des Türschlosses her befestigbar ist, wird erreicht, dass eine Demontage des Bedienelementes alleine von der Vorderseite des Türschlosses her ausgeschlossen werden kann. Auf diese Weise wird vermieden, dass das Bedienelement von der Vorderseite des Türschlosses her unbemerkt demontiert werden und so verloren gehen kann. Um eine ungewollte Demontage weiter zu erschweren und um das verwendete Montageelement zu verbergen, ist außerdem eine verschiebbare Blende zur Verdeckung des Befestigungselementes vorgesehen.Due to the fact that the operating element can be fastened from the rear side of the door lock, it is achieved that disassembly of the operating element alone from the front of the door lock can be precluded. In this way it is avoided that the control element can be disassembled unnoticed from the front of the door lock forth and can be lost. In order to further complicate an unwanted disassembly and to hide the mounting element used, also a sliding panel for covering the fastener is provided.

Eine besonders sichere Montage kann erreicht werden, wenn das Befestigungselement als Schraube ausgebildet ist. Eine einfachere Montage kann zum Beispiel erreicht werden, wenn als Befestigungselement eine Art Bajonettverschluss vorgesehen ist.A particularly secure installation can be achieved if the fastening element is designed as a screw. A simpler installation can be achieved, for example, if a kind of bayonet closure is provided as the fastening element.

Um eine ungewollte Demontage weiter zu erschweren und um ein ungewolltes Freilegen des Befestigungselementes zu verhindern, kann eine Fixiervorrichtung zur lösbaren Festlegung der Blende in einem verdeckten Zustand, in dem sie das Befestigungselement verdeckt, vorgesehen sein. Auf diese Weise kann erreicht werden, dass die Blende in einem Zustand, in dem sie über dem Befestigungselement angeordnet ist, fixiert wird und so ein ungewolltes Verschieben der Blende nur nach einer Lösung der Fixiervorrichtung möglich ist.In order to further complicate an unwanted disassembly and to prevent unintentional exposure of the fastener, a fixing device for releasably securing the panel in a hidden state in which it conceals the fastener may be provided. In this way it can be achieved that the aperture in a state in which they are above the Fastening element is arranged, is fixed and so an unintentional displacement of the diaphragm is possible only after a solution of the fixing device.

Eine besonders einfache Ausgestaltung der Fixiervorrichtung kann erreicht werden, wenn diese als Rastanordnung ausgebildet ist. Eine solche Rastanordnung kann bspw. durch eine Öffnung, die in der Blende vorgesehen ist, gelöst werden. Bevorzugterweise ist die Öffnung in der Blende als kleine Bohrung ausgestaltet, die bspw. mit der Spitze eines Kugelschreibers oder eines Schraubendrehers durchgreifbar ist, um die Fixiervorrichtung zu lösen. Durch eine solche, vergleichsweise kleine Öffnung kann ein unauffälliger Zugriff auf die Fixiervorrichtung geschaffen werden, wobei gleichzeitig eine Funktionalität der Blende, bspw. als "geöffnet"/"geschlossen" Anzeige des Türschlosses erhalten bleiben kann.A particularly simple embodiment of the fixing device can be achieved if this is designed as a latching arrangement. Such a latching arrangement can, for example, be solved by an opening which is provided in the aperture. Preferably, the opening in the aperture is designed as a small bore, which, for example. With the tip of a ballpoint pen or a screwdriver is durchgreifbar to solve the fixing device. By such, relatively small opening an inconspicuous access to the fixing device can be created, at the same time a functionality of the aperture, for example. As "open" / "closed" display of the door lock can be maintained.

Eine gut handhabbare Anordnung wird geschaffen, wenn die Rastanordnung einen Rastbolzen aufweist, der in dem verdeckten Zustand in eine Rastausnehmung der Blende eingreift. Ein solcher Rastbolzen kann dann durch einen Eingriff in die Öffnung der Blende zurückgedrängt werden, sodass die Rastverbindung freigegeben und die Blende verschiebbar wird.A well manageable arrangement is created when the latching arrangement comprises a latching pin which engages in the hidden state in a recess of the aperture. Such a locking bolt can then be pushed back by an engagement in the opening of the panel, so that the locking connection released and the panel is displaced.

Die Öffnung in der Blende ist dazu bevorzugt in axialer Verlängerung des Rastbolzens angeordnet. Auf diese Weise kann besonders einfach eine Betätigung des Rastbolzens in axialer Richtung erreicht werden, ohne dass eine besondere Führung des Rastbolzens notwendig wäre.The opening in the aperture is preferably arranged in the axial extension of the locking bolt. In this way, an operation of the locking bolt in the axial direction can be achieved particularly easily without a special leadership of the locking bolt would be necessary.

Wenn eine Anordnung der Öffnung in axialer Verlängerung des Rastbolzens jedoch nicht möglich ist, kann der Rastbolzen blendenseitig einen Auslöseteller aufweisen, der den Rastbolzen in radialer Richtung vergrößert, sodass eine größere Fläche zur Betätigung des Rastbolzens geschaffen wird.However, if an arrangement of the opening in the axial extension of the latching bolt is not possible, the latching pin can have a shutter plate on the blinding side, which holds the latching bolt enlarged in the radial direction, so that a larger area is created for actuating the locking bolt.

In diesem Fall ist es sinnvoll, wenn für den Rastbolzen eine Linearführung vorgesehen ist. Durch eine solche Linearführung wird erreicht, dass der Rastbolzen bei einer Betätigung, die nicht unmittelbar in axialer Verlängerung des Rastbolzens stattfindet, weiterhin in axialer Richtung geführt ist und so nicht verkanten kann.In this case, it makes sense if a linear guide is provided for the locking bolt. By such a linear guide is achieved that the locking pin in an operation that does not take place directly in the axial extension of the locking bolt, continues to be guided in the axial direction and so can not tilt.

Für eine möglichst unauffällige Anbringung der Öffnung kann es sinnvoll sein, diese im Bereich des Auslösetellers exzentrisch anzuordnen. Es kann so erreicht werden, dass die Öffnung in der Blende bspw. in einem unteren Eckbereich angeordnet werden kann, sodass sie im normalen Betrieb des Türschlosses nicht als störend empfunden wird.For a most inconspicuous attachment of the opening, it may be useful to arrange them eccentrically in the region of the release plate. It can be achieved so that the opening in the aperture, for example. In a lower corner area can be arranged so that it is not bothersome in normal operation of the door lock.

Um eine zuverlässige Fixierung der Blende im verdeckten Zustand zu gewährleisten, kann eine Feder zur Vorspannung des Rastbolzens vorgesehen sein. Auf diese Weise wird erreicht, dass der Rastbolzen in verdecktem Zustand zuverlässig durch die Vorspannung der Feder in die Rastausnehmung der Blende gedrückt wird und so ein ungewolltes Entriegeln der Rastanordnung vermieden wird.In order to ensure a reliable fixation of the aperture in the hidden state, a spring may be provided for biasing the locking bolt. In this way it is achieved that the locking pin is reliably pressed in the hidden state by the bias of the spring in the recess of the panel and so an unintentional unlocking of the latch assembly is avoided.

Um die Blende im Servicefall besser handhabbar zu machen, weist diese bevorzugt eine Servicelasche auf, die, wenn die Blende aus dem verdeckten Zustand in einen Servicezustand überführt wird, bspw. seitlich im Bereich des Riegels aus dem Türschloss herausgeschoben wird, sodass eine Rückführung in den verdeckten Zustand über diese Servicelasche erreicht werden kann.In order to make the panel easier to handle when servicing, this preferably has a service tab, which, when the panel is transferred from the hidden state to a service state, for example, laterally in the region of the latch is pushed out of the door lock, so that a return to the concealed state can be achieved via this service tab.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die beigefügten Figuren eingehend erläutert.The invention will be explained in detail below with reference to an embodiment with reference to the accompanying figures.

The door lock 1 sits in a slot 2 of a door leaf of a door and is fixed there by means of fastening screws 12. In the in FIG. 1 shown view is also a front of the door lock 1 can be seen, on which a trained as a slide control element 3 is arranged. The operating element 3 is seated in an upper region of a handle 5 for actuating the door designed as a sliding door. The operating element 3 is positively fitted in this upper area in a recess 7 of the handle 5. By a guide within the door lock 1, the control element 3 is exclusively in the operating direction, ie in the present case from left to right and vice versa, movable.

Damit eine Montage des Türschlosses 1 in dem Einschubfach 2 des Türblattes möglich ist, ist es notwendig, das Bedienelement 3 für den Einbauvorgang von dem Türschloss 1 zu entfernen und erst in eingebautem Zustand wieder zu montieren. Die Befestigung des Bedienelementes 3 erfolgt im vorliegenden Fall von der Rückseite des Türschlosses 1, d. h. von der in Figur 1 dem Betrachter abgewandten Seite des Türschlosses 1 her.Thus, an assembly of the door lock 1 in the insertion compartment 2 of the door leaf is possible, it is necessary to remove the control element 3 for the installation process of the door lock 1 and to assemble only in the installed state. The attachment of the control element 3 takes place in the present case of the back of the door lock 1, ie from the in FIG. 1 the viewer facing away from the door lock 1 ago.

Figur 2 zeigt das Türschloss 1 aus Figur 1 in ausgebautem Zustand. Figur 2 zeigt dabei eine Rückansicht des Schlosses, wobei das Schloss in Figur 2 außerdem in verriegelter Stellung zum Verschließen der Türe gezeigt ist. FIG. 2 shows the door lock 1 off FIG. 1 in good condition. FIG. 2 shows a rear view of the castle, the castle in FIG. 2 also shown in locked position for closing the door.

Das Türschloss 1 weist zur Aufnahme einer Verriegelungsmechanik des Türschlosses 1 ein langgestrecktes Gehäuse 11 auf, das, wie in Figur 1 gezeigt, in dem Einschubfach 2 des Türblattes montierbar ist. In der in Figur 2 dargestellten Ansicht ist eine dem Bedienelement 3 gegenüberliegend angeordnete Blende 15 erkennbar, die im vorliegenden Ausführungsbeispiel als sogenannte Rot-Grün-Blende ausgebildet ist und entsprechend ihrer Farbcodierung einen Verriegelungszustand des Türschlosses 1 anzeigt. Die Blende 15 weist außerdem eine Öffnung 17 auf, mittels derer ein Durchgriff auf eine hinter der Blende 15 angeordnete Fixiervorrichtung in Form einer Rastanordnung zur Fixierung der Blende 15 ermöglicht wird.The door lock 1 has to receive a locking mechanism of the door lock 1 on an elongated housing 11 which, as in FIG. 1 shown in the insertion compartment 2 of the door panel is mounted. In the in FIG. 2 View shown is a control element 3 opposite arranged aperture 15 can be seen, which is formed in the present embodiment as a so-called red-green panel and displays a locking state of the door lock 1 according to their color coding. The aperture 15 also has an opening 17, by means of which a passage on a behind the aperture 15 arranged fixing device in the form of a latching arrangement for fixing the aperture 15 is made possible.

Die Öffnung 17 dient auch zur Betätigung des Türschlosses 1 von der Seite aus an der die Blende 15 angebracht ist. In einem Notfall, wenn z.B. jemand eingeschlossen ist und nicht mehr selbst in der Lage ist zu öffnen, kann das Türschlosses 1 bspw. mit einem Kugelschreiber geöffnet werden, indem der Kugelschreiber in die Öffnung 17 gesteckt wird und somit der Kugelschreiber als Betätigungsgriff dient um den Schlossmechanismus und damit den Riegel zu verschieben. Die Öffnung 17 hat damit in diesem konkreten Ausführungsbeispiel zwei Funktionen die nicht voneinander abhängen.The opening 17 also serves to actuate the door lock 1 from the side on which the diaphragm 15 is mounted. In an emergency, for example, if someone is included and is no longer able to open, the door lock 1 can be opened, for example, with a pen by the ballpoint pen is inserted into the opening 17 and thus the pen as an operating handle is used to the lock mechanism and to move the bolt. The opening 17 has thus in this particular embodiment, two functions that do not depend on each other.

Wie bereits erwähnt, ist das Türschloss 1 in Figur 2 in Schließstellung gezeigt, d. h. dass ein Riegel 13, der bei Betätigung des Bedienelementes 3 in Schließrichtung seitlich aus dem Türschloss 1 herausfährt, ausgefahren ist. Der Riegel 13 erstreckt sich im vorliegenden Ausführungsbeispiel bogenförmig nach unten, sodass durch die sich nach unten erstreckende Komponente eine Verriegelung einer Schiebetür ermöglicht wird.As already mentioned, the door lock is 1 in FIG. 2 shown in the closed position, ie that a bolt 13, which moves out of the door lock 1 when the operating element 3 is actuated laterally in the closing direction, has been extended. The bolt 13 extends in the present embodiment arcuately down, so that by the downwardly extending component locking a sliding door is made possible.

Figur 3 zeigt einen Schnitt entlang der Linie A-A durch das Türschloss 1 aus Figur 2. In dieser Schnittdarstellung ist besonders gut die Befestigung des Bedienelementes 3 sowie die für die Blende 15 vorgesehene Rastanordnung zu erkennen. FIG. 3 shows a section along the line AA through the door lock 1 FIG. 2 , In this sectional view, the fastening of the operating element 3 and the detent arrangement provided for the aperture 15 can be seen particularly well.

Das Bedienelement 3 weist eine mit einem Gewinde versehene Bohrung 32 auf, sodass es mittels einer Befestigungsschraube 33 in dem Türschloss 1 fixierbar ist. Die Blende 15 ist durch die Rastanordnung, bestehend aus einem Rastbolzen 34 sowie einem Rücksprung 19, der als Rastöffnung in der Blende 15 dient, mit dem Bedienelement 3 verbunden. Die Blende 15 wird damit bei einer Bewegung des Bedienelementes 3 mit verschoben und kann so über ein geeignet angeordnetes Sichtfenster 9 den Verriegelungszustand des Türschlosses 1 anzeigen.The operating element 3 has a bore 32 provided with a thread, so that it can be fixed in the door lock 1 by means of a fastening screw 33. The aperture 15 is connected to the control element 3 by the latching arrangement, consisting of a latching pin 34 and a recess 19, which serves as a latching opening in the aperture 15. The aperture 15 is thus moved with a movement of the control element 3 and can thus indicate the locking state of the door lock 1 via a suitably arranged viewing window 9.

Um eine sichere Verrastung der Blende 15 mit dem Rastbolzen 34 zu gewährleisten, ist dieser mittels einer Schraubenfeder 38 in Rastrichtung federbelastet. Der Rastbolzen 34 ist im Wesentlichen pilzförmig aufgebaut und weist einen Auslöseteller 35, der den Rastbolzen an der der Feder 38 abgewandten Seite radial vergrößert sowie einen der Feder 38 zugewandten Führungsabschnitt 36 auf. Der Führungsabschnitt 36 ist in einer Linearführung 37 aufgenommen, um ein Verkanten des Rastbolzens 34 im Inneren der Anordnung zu verhindern.In order to ensure a secure locking of the panel 15 with the locking pin 34, this is spring-loaded by means of a coil spring 38 in the latching direction. The locking pin 34 is constructed substantially mushroom-shaped and has a release plate 35 which radially increases the locking pin on the side facing away from the spring 38 and a guide portion facing the spring 38 36 on. The guide portion 36 is received in a linear guide 37 to prevent tilting of the locking bolt 34 inside the assembly.

Die Linearführung 37 ist insbesondere notwendig, da die Öffnung 17 (in der vorliegenden Figur nicht ersichtlich) in einem unteren Bereich des Sichtfensters 9 angeordnet ist, sodass ein Eingriff in die Öffnung 17 exzentrisch auf den Rastbolzen 34 respektive auf dessen Auslöseteller 35 wirkt und damit eine Kippbewegung induzieren würde.The linear guide 37 is particularly necessary because the opening 17 (not visible in the present figure) is arranged in a lower region of the viewing window 9, so that an engagement in the opening 17 acts eccentrically on the locking pin 34 respectively on the release plate 35 and thus a Would induce tilting movement.

Figur 4 zeigt das Türschloss aus Figur 2 in Servicestellung, d. h. in einer Stellung, in der das Bedienelement 3 frei montierbar bzw. demontierbar ist. FIG. 4 shows the door lock FIG. 2 in the service position, ie in a position in which the operating element 3 is freely mountable or removable.

In Servicestellung ist die Blende 15 durch Lösen des Rastmechanismus verschiebbar und wie in Figur 4 dargestellt zu Servicezwecken seitlich verschoben. In dieser Servicestellung ist die Befestigungsschraube 33 für das Bedienelement 3 zugänglich, sodass eine Montage bzw. Demontage des Bedienelementes 3 stattfinden kann. In Figur 4 ist außerdem besonders gut der Auslöseteller 35 des Rastbolzens 34 zu erkennen. Diese Vergrößerung der Angriffsfläche auf den Rastbolzen 34 bewirkt, dass die Öffnung 17 zum Auslösen der Rastverbindung am unteren Ende des in Figur 4 sichtbaren Sichtfensters 9 angeordnet sein kann und damit im Normalbetrieb des Türschlosses 1 nur eine geringe optische Irritation darstellt. Um eine bessere Handhabbarkeit der Blende 15 in Servicestellung zu gewährleisten, weist diese eine Servicelasche 21 auf, die, wenn die Blende 15 seitlich verschoben wird, riegelseitig aus dem Türschloss 1 hervortritt.In service position, the diaphragm 15 is displaceable by releasing the locking mechanism and as in FIG. 4 displayed laterally for service purposes. In this service position, the fastening screw 33 is accessible to the operating element 3, so that assembly or disassembly of the control element 3 can take place. In FIG. 4 is also particularly well the release plate 35 of the locking bolt 34 can be seen. This enlargement of the engagement surface on the locking pin 34 causes the opening 17 to trigger the latching connection at the lower end of in FIG. 4 visible viewing window 9 may be arranged and thus represents only a slight visual irritation in normal operation of the door lock 1. In order to ensure better handling of the panel 15 in the service position, this has a service tab 21 which, when the panel 15 is displaced laterally, emerges from the door lock 1 on the latch side.

Es wird nachfolgend der Einbau des zuvor beschriebenen Türschlosses beispielhaft erläutert.The installation of the previously described door lock will be explained below by way of example.

In einem ersten Schritt wird das Türschloss 1, wie es bspw. in Figur 2 gezeigt ist, zum Einbau vorbereitet. Dafür wird mit einem spitzen Gegenstand, bspw. einem Schraubendreher, der Rastbolzen 34 durch die Öffnung 17 nach innen gedrückt, sodass dieser aus der Rastausnehmung 19, die rückseitig an der Blende 15 angeordnet ist, zurückweicht und die Blende 15 damit verschiebbar ist.In a first step, the door lock 1, as it is, for example, in FIG. 2 shown, prepared for installation. For this purpose, the locking pin 34 is pressed by the opening 17 inwardly with a pointed object, eg. A screwdriver, so that it from the recess 19, which is arranged at the back of the aperture 15, recedes and the aperture 15 is thus displaced.

Die Blende 15 wird dann zum Einbau seitlich verschoben, sodass die aus den Figuren 3 und 4 ersichtliche Bohrung für die Befestigungsschraube 33 für das Bedienelement 3 freigegeben wird.The aperture 15 is then moved laterally for installation, so that from the Figures 3 and 4 apparent hole for the mounting screw 33 is released for the control element 3.

In diesem Zustand wird das Türschloss 1 in das Einschubfach 2 des Türblattes eingeschoben und dort mittels Befestigungsschrauben 12 fixiert. Für die Montage des Bedienelementes 3 wird dieses, ausgestattet mit der Druckfeder 38, von der Vorderseite her auf das eingebaute Türschloss 1 aufgesetzt und von der Rückseite her mittels der Befestigungsschraube 33 fixiert. Mittels der seitlich aus dem Türschloss 1 hervorstehenden Servicelasche 21 kann die Blende 15 nach Befestigung des Bedienelementes 3 zurück in ihre Ausgangsposition verbracht werden, sodass der Rastbolzen 34 wieder in den Rücksprung 19 der Blende 15 einrasten kann und die Blende 15 in dieser Position fixiert ist. Die Blende 15 ist damit wieder mit dem Bedienelement 3 verbunden, sodass eine Anzeige des Verriegelungszustandes des Türschlosses 1 wieder möglich ist.In this state, the door lock 1 is inserted into the insertion compartment 2 of the door leaf and fixed there by means of fastening screws 12. For the assembly of the operating element 3, this, fitted with the compression spring 38, placed on the built-in door lock 1 from the front side and fixed from the rear side by means of the fastening screw 33. By means of the laterally protruding from the door lock 1 service tab 21, the aperture 15 can be spent after attachment of the control element 3 back to its original position, so that the locking pin 34 can engage in the recess 19 of the panel 15 again and the aperture 15 is fixed in this position. The panel 15 is thus again connected to the control element 3, so that an indication of the locking state of the door lock 1 is possible again.
