Description

Die Erfindung betrifft eine Vorrichtung zur elektro-mechanischen Betätigung eines Riegels zur Freigabe einer Fluchttür nach dem Oberbegriff des Anspruches 1.The invention relates to a device for the electro-mechanical actuation of a bolt for releasing an escape door according to the preamble of claim 1.

In der Technik sind Verriegelungen für Fluchttüren oder dergleichen bekannt, bei welchen nach einer Beaufschlagung der Fluchttür durch eine Druckkraft ein in Sperrstellung befindlicher Riegel in das Schloß zurückgedreht werden soll. Gerade für den Anwendungsfall, für den eine derartige Vorrichtung zur Freigabe einer Fluchttür auszulegen ist, ist nicht gewährleistet, daß die Fluchttür hinreichend zuverlässig geöffnet wird. Es komnmt relativ häufig vor, daß der Riegel im Panikfall, d. h. wenn die Fluchttür von einer Seite unvermittelt mit hohem Druck beaufschlagt wird, gegenüber dem Widerlager verklemmt und nicht ins Schloß zurückweicht, so daß die Tür geöffnet werden kann. In der Ausnahmesituation, in welcher eine derartige Vorrichtung zur Freigabe einer Fluchttür schlagartig mit sehr hohem Druck beaufschlagt wird, wobei die Scherbelastung auf die Verriegelungselemente quer zur Richtung der Druckkraft sehr groß ist, war bisher ein Öffnen der Fluchttür mit ausreichender Sicherheit nicht gewährleistet.Locking devices for escape doors or the like are known in the art, in which, after the escape door has been acted upon by a compressive force, a bolt which is in the locked position is to be turned back into the lock. Especially for the application for which such a device for releasing an escape door is to be designed, it is not guaranteed that the escape door is opened with sufficient reliability. It happens relatively often that the bolt in the event of panic, i.e. H. if the escape door is suddenly subjected to high pressure from one side, jammed against the abutment and does not move back into the lock so that the door can be opened. In the exceptional situation in which such a device for releasing an escape door is suddenly subjected to very high pressure, the shear load on the locking elements across the direction of the compressive force being very high, it has previously not been possible to ensure that the escape door was opened with sufficient security.

Eine gattungsgemäße Vorrichtung ist aus der GB-A 13450210 bekannt. Das Hebelgestänge besteht hierbei aus einer mit dem Anker des Elektromagneten verbundenen Schubstange sowie einem zweiarmigen Hebel, der mit einem Arm an der Schubstange angelenkt ist. Der andere Arm steht in Eingriff mit dem Riegel. Vom Riegel ausgehende Schubkräfte werden über den Hebel auf die Schubstange und den Anker übertragen, so daß nicht ausgeschlossen ist, daß das Hebelgestänge oder die elektromagnetischen Bauteile beschädigt werden, wenn im verriegelten Zustand der Versuch gemacht wird, die Tür zu öffnen bzw. den Riegel gewaltsam zurückzuschieben. Im Gefahrenfall kann dann die Funktion beeinträchtigt sein.A generic device is known from GB-A 13450210. The lever linkage here consists of a connecting rod connected to the armature of the electromagnet and a two-armed lever which is articulated with one arm on the connecting rod. The other arm is engaged with the latch. Shear forces emanating from the bolt are transmitted via the lever to the push rod and the armature, so that it cannot be ruled out that the lever linkage or the electromagnetic components will be damaged if an attempt is made in the locked state to open the door or to force the bolt push back. The function may then be impaired in the event of danger.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, bei welcher das Hebelgestänge bei blockierten Riegeln gegen Beschädigung geschützt ist.The invention has for its object to provide a device of the type mentioned, in which the lever linkage is protected against damage when the bolts are blocked.

Diese Aufgabe wird durch die im Kennzeichnungsteil des Anspruches 1 angegebenen Merkmale gelöst. Bevorzugte Weiterbildungen sind in den abhängigen Ansprüchen beschrieben.This object is achieved by the features specified in the characterizing part of claim 1. Preferred developments are described in the dependent claims.

Die Erfindung sieht demnach vor, daß der Riegel selbst durch eine elektro-magnetisch steuerbare Sperrklinke blockiert und freigegeben werden kann. In dem Betriebszustand, in welchem in einem Elektromagnet Strom fließt, wird die Sperrklinke in einer Blockierstellung gehalten, so daß der Riegel nicht verschoben werden kann. Wenn der Elektromagnet stromlos ist, kann die Sperrklinke aus der Blockierstellung bewegt werden. Das heißt, in einem Notfall, wenn kein Strom fließt, kann der Riegel bei entsprechender Druckbeaufschlagung in die Öffnungsstellung zurückgeschoben werden, ohne dabei durch die Sperrklinke behindert zu sein.The invention accordingly provides that the bolt itself can be blocked and released by an electro-magnetically controllable pawl. In the operating state in which current flows in an electromagnet, the pawl is held in a blocking position so that the bolt cannot be moved. When the electromagnet is de-energized, the pawl can be moved out of the blocking position. This means that in an emergency, when there is no current flowing, the bolt can be pushed back into the open position with the appropriate pressure, without being hindered by the pawl.

Die Erfindung schlägt damit eine Vorrichtung zur elektro-mechanischen Betätigung eines Riegels zur Freigabe einer verriegelten Tür vor, durch welche die Tür im Ruhezustand einerseits fest verriegelt wird und durch welche andererseits auch bei einem schlagartigen Drücken auf die Tür nach abgeschaltetem Strom die Tür sicher geöffnet werden kann.The invention thus proposes a device for the electro-mechanical actuation of a bolt for releasing a locked door, through which the door is firmly locked in the idle state, on the one hand, and through which, on the other hand, the door is securely opened even when the door is suddenly pressed after the power has been switched off can.

Damit die erfindungsgemäße Vorrichtung in einem möglichst flachen Schloß untergebracht werden kann, ist vorgesehen, daß die Sperrklinke zur Freigabe des Riegels um eine im wesentlichen vertikal zur Bewegungsebene des Riegels ausgerichtete Achse schwenkbar ist. Die Sperrklinke wird somit in der gleichen Ebene wie der Riegel während seiner Bewegungen in eine der beiden Extremstellungen betätigt.So that the device according to the invention can be accommodated in a lock that is as flat as possible, it is provided that the pawl can be pivoted about an axis oriented essentially vertically to the plane of movement of the lock to release the lock. The pawl is thus actuated in the same plane as the bolt during its movements in one of the two extreme positions.

Durch die Bewegung des Riegels in seine Öffnungsstellung wird die Sperrklinke aus der Blokkierstellung ausgeschwenkt. Durch eine Feder kann die Sperrklinke dann, wenn der Riegel wieder in seine Sperrstellung ausgefahren wurde, in die Blockierstellung zurückgeschwenkt werden.The pawl is pivoted out of the blocking position by the movement of the bolt into its open position. The pawl can be pivoted back into the blocking position by means of a spring when the bolt has been extended again into its blocking position.

In der Blockierstellung wird die Sperrklinke entweder durch direkte Beaufschlagung mit der Anzugskraft eines Elektromagneten oder über ein von dem Elektromagneten beaufschlagtes Hebelgestänge gehalten. In dem Betriebszustand, in welchem Strom fließt, wird das Hebelgestänge angezogen. Ein Abschnitt des Hebelgestänges ist in diesem Betriebszustand in die Bewegungsbahn der Klinke geschwenkt, so daß diese in ihrer Blockierstellung arretiert ist.In the blocking position, the pawl is held either by direct application of the pulling force of an electromagnet or by a lever linkage acted upon by the electromagnet. In the operating state in which current flows, the lever linkage is tightened. In this operating state, a section of the lever linkage is pivoted into the path of movement of the pawl, so that it is locked in its blocking position.

In dem Betriebszustand, in welchem kein Strom fließt, wird das Hebelgestänge durch die Einwirkung einer Feder geschwenkt, so daß der Abschnitt des Hebelgestänges, welcher in die Bewegungsbahn der Sperrklinke eingreift, zurückgezogen wird. Damit wird die Sperrklinke freigegeben, so daß der Riegel ungehindert in seine Öffnungsstellung bewegt werden kann.In the operating state in which no current flows, the lever linkage is pivoted by the action of a spring, so that the portion of the lever linkage which engages in the path of movement of the pawl is withdrawn. This releases the pawl so that the bolt can be moved freely into its open position.

Um den Riegel von der Öffnungsstellung wieder in die Schließstellung zu bringen, ist eine weitere Feder vorgesehen, die den Riegel in axialer Richtung aus dem Schloß herausschiebt. Die axiale Bewegung des Riegels aus dem Schloß heraus wird durch einen ersten, am Riegel angebrachten Ansatz, der gegen das Schloßgehäuse anstößt, begrenzt. Darüber hinaus weist der Riegel einen zweiten Ansatz auf, der die Verschiebung in die Öffnungsstellung dadurch begrenzt, daß er am Schloßgehäuse oder an einem Abschnitt davon anstößt.In order to bring the bolt from the open position back into the closed position, a further spring is provided which pushes the bolt out of the lock in the axial direction. The axial movement of the bolt out of the lock is limited by a first attachment, which is attached to the bolt and abuts the lock housing. In addition, the bolt has a second approach, which limits the displacement into the open position in that it abuts the lock housing or a portion thereof.

Nach dem Grundgedanken der Erfindung ist vorgesehen, daß der Riegel an seinem vorderen Endabschnitt wenigstens auf der Seite, die der mit einer Druckkraft beaufschlagbaren Türseite zugewandt ist, eine Gleitfläche aufweist. Die aufgebrachte Druckkraft wird unmittelbar auf diese Gleitfläche übertragen. Infolge der durch die Erfindung vorgeschlagenen Neigung der Gleitfläche in die Richtung der Druckkraft wird der Riegel durch die Druckbeaufschlagung in die Öffnungsstellung zurückbewegt, wobei die Gleitfläche gegenüber einem Widerlager verschoben wird. Die Öffnungsstellung des Riegels ist dann erreicht, wenn der Riegel bezüglich des dem Schloß gegenüber angeordneten Widerlagers so weit in seine Öffnungsstellung zurückgeschoben wurde, daß er an dem Widerlager vorbeigleiten kann.According to the basic idea of the invention, it is provided that the latch has a sliding surface at least at its front end section on the side facing the door side which can be subjected to a compressive force. The applied pressure force is transferred directly to this sliding surface. As a result of the inclination of the sliding surface in the direction of the compressive force proposed by the invention, the bolt is moved back into the open position by the pressurization, the sliding surface being displaced relative to an abutment. The opening position of the bolt is reached when the bolt has been pushed back so far into its open position with respect to the abutment opposite the lock that it can slide past the abutment.

Für den Fall, daß die Fluchttür in einem Notfall nach beiden Seiten zu öffnen sein soll, ist vorgesehen, daß der vordere Endabschnitt des Riegels auf seinen beiden, dem Kraftangriff zugewandten Seiten jeweils eine Gleitfläche aufweist. Die Gleitflächen sind jeweils in Richtung der Druckkraft geneigt.In the event that the escape door is to be opened on both sides in an emergency, it is provided that the front end section of the bolt has a sliding surface on both of its sides facing the force application. The sliding surfaces are inclined in the direction of the compressive force.

Die Fluchttür kann damit ohne Unterschied in einem Notfall nach beiden Seiten geöffnet werden. Unabhängig davon wird die Tür im Ruhezustand nach beiden Seiten sicher verriegelt. In der Technik wird diese Art der Verriegelung auch als Ruhestromverriegelung bezeichnet.The escape door can thus be opened on both sides without difference in an emergency. Regardless of this, the door is securely locked on both sides in the idle state. In technology, this type of locking is also referred to as closed-circuit locking.

Die beschriebenen Ausführungsbeispiele mit einer oder mit zwei Gleitflächen des Riegels am vorderen Endabschnitt können jeweils ohne Unterschied im Türblatt oder im Türrahmen eingelassen werden.The exemplary embodiments described with one or two sliding surfaces of the latch at the front end section can each be inserted in the door leaf or in the door frame without any difference.

Je nach dem für den Riegel verwendeten Werkstoff können die am vorderen Endabschnitt des Riegels angeordneten Gleitflächen in die Richtung der Druckkraft um einen bestimmten Winkelbereich geneigt sein. Bei Werkstoffen mit guten Gleiteigenschaften kann der Anstellwinkel noch etwa 70° betragen, um ein sicheres Öffnen der Fluchttür zu gewährleisten. In einem bevorzugten Ausführungsbeispiel wird ein Anstellwinkel von 45° gewählt. Hierbei ist einerseits die Öffnungsfunktion und andererseits die Verriegelungsfunktion der Vorrichtung in einem sehr guten Maß gewährleistet.Depending on the material used for the bolt, the sliding surfaces arranged on the front end section of the bolt can be inclined in the direction of the compressive force by a certain angular range. For materials with good sliding properties, the angle of attack can still be around 70 ° to ensure that the escape door can be opened safely. In a preferred embodiment, an angle of attack of 45 ° is selected. On the one hand, the opening function and, on the other hand, the locking function of the device are guaranteed to a very good degree.

Als annähernd gleichwertig ist es zu betrachten, wenn statt des mit einer Gleitfläche abgeschrägten vorderen Endabschnittes des Riegels ein in diesem Bereich rechteckig ausgebildeter Riegel verwendet wird und wenn dieser Riegel gegen ein um einen entsprechenden Winkel abgeschrägtes Widerlager (Schließblech) zur Anlage kommt, oder wenn ein abgeschrägter Riegel gegen ein nicht abgeschrägtes Widerlager anliegt. Die mit der Erfindung vorgeschlagene Gleitfläche kann in vorteilhafter Weise je nach Anwendungsfall eben oder gewölbt ausgebildet sein.It is to be regarded as approximately equivalent if, instead of the front end section of the bolt, which is bevelled with a sliding surface, a bolt which is rectangular in this area is used and if this bolt comes into contact with an abutment (striking plate) which is inclined by a corresponding angle, or if a bevelled latch is in contact with a non-bevelled abutment. The sliding surface proposed by the invention can advantageously be flat or curved depending on the application.

Für die Erfindung sind Riegel verwendbar, die beispielsweise einen kreisförmigen oder einen sonst üblicherweise verwendeten Querschnitt aufweisen.Bars can be used for the invention, which have, for example, a circular or otherwise normally used cross section.

Die Erfindung wird nachfolgend beispielsweise anhand der Zeichnung beschrieben; es zeigen:

  • Figur 1 eine Draufsicht auf die Vorrichtung zur Freigabe einer Tür im verriegelten Zustand,
  • Figur 2 die Vorrichtung nach Fig.1 im stromlosen Zustand,
  • Figur 3 Ansichten der Sperrklinke von oben, von der Seite und von unten sowie
  • Figur 4 eine Draufsicht auf ein Schloß mit Riegel in Schließstellung.
The invention is described below, for example with reference to the drawing; show it:
  • FIG. 1 shows a top view of the device for releasing a door in the locked state,
  • 2 shows the device according to FIG.
  • Figure 3 views of the pawl from above, from the side and from below as well
  • Figure 4 is a plan view of a lock with a bolt in the closed position.

In Fig. ist ein Schloß 1 gezeigt, bei welchem ein von einem Elektromagnet 3 angezogenes Hebelgestänge 5 eine Sperrklinke 7 in einer Blockierung hält, so daß diese den Riegel 9 daran hindert, ins Schloß 1 zurückgeschoben zu werden. Der Riegel 9 ragt mit seinem vorderen Endabschnitt 11 aus dem Gehäuse des Schlosses 1 heraus; er befindet sich somit in Schließstellung. Im vorliegenden Ausführungsbeispiel ist der Riegel 9 quaderförmig ausgebildet und weist an seinem hinteren Ende einen Ansatz 13 auf, der in der gezeigten Stellung gegen die Sperrklinke 7 anliegt. Weiterhin ist am Riegel 9 ein Ansatz 15 vorgesehen, der in der gezeigten Stellung gegen einen Gehäuseabschnitt 17 anliegt, so daß der Riegel 9 nur um den gezeigten vorderen Endabschnitt 11 aus dem Schloß herausragen kann. Der Riegel 9 wird somit an dem Ansatz 15 durch die Sperrklinke 7 und den Gehäuseabschnitt 17 in axialer Richtung definiert gehalten. Ein unbeabsichtigtes Verschieben kann in der gezeichneten Betriebsstellung nicht auftreten. In die gezeigte Stellung wurde der Riegel 9 durch die Druckfeder 19 gebracht, welche zur Verschiebung des Riegels 9 von der Öffnungstellung in die Schließstellung dient. Die Sperrklinke 7 ist um die Achse 21 schwenkbar gelagert. In der gezeigten Stellung wird die Sperrklinke 7 durch eine Blattfeder 23 gehalten, welche gegen einen an der Sperrklinke 7 befestigten Zapfen drückt, so daß die Sperrklinke 7 gegen einen gehäusefesten Stift 27 anstößt.In Fig. A lock 1 is shown, in which a lever linkage 5 attracted by an electromagnet 3 holds a pawl 7 in a blockage, so that this prevents the bolt 9 from being pushed back into the lock 1. The bolt 9 protrudes with its front end portion 11 from the housing of the lock 1; it is therefore in the closed position. In the present exemplary embodiment, the bolt 9 is cuboid and has at its rear end a shoulder 13 which in the position shown bears against the pawl 7. Furthermore, a projection 15 is provided on the bolt 9, which in the position shown bears against a housing portion 17, so that the bolt 9 can only protrude from the lock by the front end portion 11 shown. The bolt 9 is thus held in a defined manner in the axial direction on the extension 15 by the pawl 7 and the housing section 17. Unintentional shifting cannot occur in the drawn operating position. In the position shown, the bolt 9 was brought by the compression spring 19, which is used to move the bolt 9 from the open position to the closed position. The pawl 7 is pivotally mounted about the axis 21. In the position shown, the pawl 7 is held by a leaf spring 23 which presses against a pin attached to the pawl 7, so that the pawl 7 abuts a pin 27 fixed to the housing.

Damit die Sperrklinke 7 nicht infolge einer in axialer Richtung des Riegels 9 wirkenden Kraft entgegen dem Druck der Blattfeder 23 ausgeschwenkt werden kann, ist ein Abschnitt 29 des Hebelgestänges 5 zwischen der Sperrklinke 7 und einem gehäusefesten Bolzen 31 angeordnet. Eine auf den Riegel 9 eingeleitete und auf die Sperrklinke 7 übertragene Kraft würde über den Abschnitt 29 des Hebelgestänges 5 in den Bolzen 31 des Schloßgehäuses 1 abgeleitet. Ein Endabschnitt 33 des Hebelgestänges 5 wird von dem Elektromagnet 3, welcher unter Strom steht, angezogen, so daß der Abschnitt 29 des Hebelgestänges 5 die Sperrklinke 7 ständig verriegelt. Somit ist eine sichere Verriegelung der gesamten Vorrichtung für den Fall, daß Strom im Elektromagnet 3 fließt, gewährleistet.So that the pawl 7 cannot be pivoted against the pressure of the leaf spring 23 as a result of a force acting in the axial direction of the bolt 9, a section 29 of the lever linkage 5 is arranged between the pawl 7 and a bolt 31 fixed to the housing. A force introduced into the bolt 9 and transmitted to the pawl 7 would be derived via the section 29 of the lever linkage 5 into the bolt 31 of the lock housing 1. An end section 33 of the lever linkage 5 is attracted by the electromagnet 3, which is under current, so that the section 29 of the lever linkage 5 constantly locks the pawl 7. This ensures a secure locking of the entire device in the event that current flows in the electromagnet 3.

In Fig.2 ist die Stellung gezeigt, die die einzelnen Teile der Vorrichtung einnehmen, wenn der Elektromagnet 3 stromlos ist. In diesem Fall wird der Endabschnitt 33 des Hebelgestänges 5 durch eine Druckfeder 35 von dem Elektromagnet 3 weggedrückt und liegt gegen einen gehäusefesten Anschlag 37 an. Durch die Schwenkbewegung des Endabschnittes 33 wird der Abschnitt 29 um den Bolzen 31 verschwenkt, so daß die Sperrklinke 7 freigegeben wird. Solange über den Riegel 9 kein Druck auf die Sperrklinke 7 ausgeübt wird, bleibt die Sperrklinke 7 infolge des Druckes der Blattfeder 23 in der Ausgangsstellung stehen. Wenn der Riegel 9 durch Druckbeaufschlagung von außen in einem Notfall in das Innere des Schlosses in Richtung Öffnungsstellung verschoben wird, kann die Klinke 7 ohne weiteres in die in strichpunktierten Linien gezeichnete Stellung geschwenkt werden. Dies geschieht durch Druckbeaufschlagung der Sperrklinke 7 über den Ansatz 13. Während die Sperrklinke 7 in die in strichpunktierten Linien gezeichnete Stellung schwenkt, fährt der Riegel 9 in die Öffnungsstellung nach hinten. Damit der Riegel 9 nicht zu weit in das Schloß 1 gedrückt wird, ist der axiale Hub nach hinten durch einen gehäusefesten Anschlag 39 begrenzt. Wenn auf den vorderen Endabschnitt 11 des Riegels 9 kein Druck mehr ausgeübt wird, bewegt die Druckfeder 19 den Riegel 9 wieder in die Schließstellung. Wenn der Riegel 9 die vordere Einstellung (Schließstellung) erreicht hat, klappt die Sperrklinke 7 wieder infolge der auf sie ausgeübten Kraft durch die Blattfeder 23 in die in ausgezeichneten Linien dargestellte Ausgangslage. Wenn in dieser Stellung der Sperrklinke 7 der Elektromagnet 3 wieder unter Strom gesetzt wird, nimmt das Hebelgestänge 5 wieder die in Fig. gezeigte Position ein.2 shows the position that the individual parts of the device assume when the electromagnet 3 is de-energized. In this case, the end section 33 of the lever linkage 5 is pressed away from the electromagnet 3 by a compression spring 35 and bears against a stop 37 fixed to the housing. Due to the pivoting movement of the end section 33, the section 29 is pivoted about the bolt 31, so that the pawl 7 is released. As long as no pressure is exerted on the pawl 7 via the bolt 9, the pawl 7 remains in the initial position due to the pressure of the leaf spring 23. If, in an emergency, the bolt 9 is moved from outside in the event of an emergency into the interior of the lock in the direction of the open position, the pawl 7 can easily be pivoted into the position shown in broken lines. This is done by pressurizing the pawl 7 via the approach 13. While the Pawl 7 pivots into the position shown in dash-dotted lines, the bolt 9 moves to the open position to the rear. So that the bolt 9 is not pressed too far into the lock 1, the axial stroke to the rear is limited by a stop 39 fixed to the housing. When pressure is no longer applied to the front end section 11 of the bolt 9, the compression spring 19 moves the bolt 9 back into the closed position. When the bolt 9 has reached the front setting (closed position), the pawl 7 folds again as a result of the force exerted on it by the leaf spring 23 into the starting position shown in excellent lines. When the electromagnet 3 is energized again in this position of the pawl 7, the lever linkage 5 again assumes the position shown in FIG.

Aus Gründen der besseren Veranschaulichung ist in Fig.2 das Schließblech 53 mit der Ausnehmung 55 vom vorderen Endabschnitt 11 des Riegels 9 abgerückt dargestellt.For the sake of better illustration, the striking plate 53 with the recess 55 is shown moved away from the front end section 11 of the bolt 9 in FIG.

In Fig.3 ist die Sperrklinke 7 als Einzelteil herausgezeichnet. In den Ansichten a) und b) ist der Zapfen 25 zu sehen, gegen den ein Schenkel der Blattfeder 23 zur Anlage kommt. Mit dem Bezugszeichen 41 ist der Abschnitt der Sperrklinke 7 versehen, gegen welchen der Ansatz 13 des Riegels 9 anliegt. Die Anlagefläche 41 ist, wie insbesondere aus den Figuren 3a, 1 und 2 ersichtlich ist, gegenüber der Schwenkachse 21 um eine Exzentrität 43 versetzt. Durch diese Besonderheit wird die Schwenkbewegung der Sperrklinke 7 erleichtert.In Figure 3, the pawl 7 is drawn out as a single part. Views a) and b) show the pin 25 against which one leg of the leaf spring 23 comes to rest. The portion 41 of the pawl 7 against which the shoulder 13 of the bolt 9 bears is provided with the reference number 41. The contact surface 41, as can be seen in particular from FIGS. 3a, 1 and 2, is offset from the pivot axis 21 by an eccentricity 43. This special feature makes the pivoting movement of the pawl 7 easier.

In Fig.4 ist das Schloß 1 mit dem vorderen Endabschnitt 11 des Riegels in Schließstellung gezeigt. Der vordere Endabschnitt 11 weist zwei Gleitflächen 47 und 49 auf. Die der Türseite 51, an welcher die Kraft F angreift, zügewandte Gleitfläche 47 bildet mit der Richtung der Kraft F einen Winkel a, welcher im vorliegenden Fall in etwa 45° beträgt. Infolge der Beaufschlagung der Tür 45 durch die Kraft F gleitet der vordere Endabschnitt 11 an der Gleitfläche 47 aus dem Schließblech 53 in das Schloß zurück.In Figure 4, the lock 1 is shown with the front end portion 11 of the bolt in the closed position. The front end section 11 has two sliding surfaces 47 and 49. The sliding surface 47 facing the door side 51, on which the force F acts, forms an angle a with the direction of the force F, which in the present case is approximately 45 °. As a result of the force F acting on the door 45, the front end section 11 slides back on the sliding surface 47 from the striking plate 53 into the lock.

Grundsätzlich könnte das Schloß 1 auch im Türblatt angeordnet werden, wobei in diesem Fall die der Kraftangriffsfläche angewandte Seite des Riegels unter einem Winkel a gegen die Richtung der Druckkraft geneigt anzuordnen ist.In principle, the lock 1 could also be arranged in the door leaf, in which case the side of the bolt applied to the force application surface is to be arranged inclined at an angle a against the direction of the pressure force.

Das in Fig.4 gezeigte Schloß, bei welchem der vordere Endabschnitt 11 des Riegels mit zwei Gleitflächen 47 und 49 ausgebildet ist, könnte auch mit einer Kraft F' beaufschlagt werden, die entgegengesetzt der eingezeichneten Kraft F ausgerichtet ist und die auf einen Türabschnitt einwirkt, welcher der Gleitfläche 49 benachbart angeordnet ist. In dem gezeichneten Ausführungsbeispiel sind die Gleitflächen 47 und 49 eben ausgebildet.The lock shown in FIG. 4, in which the front end portion 11 of the bolt is formed with two sliding surfaces 47 and 49, could also be subjected to a force F 'which is oriented counter to the force F shown and which acts on a door portion. which is arranged adjacent to the sliding surface 49. In the illustrated embodiment, the sliding surfaces 47 and 49 are flat.
