Abstract

A lock comrises a catch (5) and bolt (4), which can be actuated by a lock cylinder (22), the catch (5) also being retractable by a pusher nut (8), and a catch locking slide (35). In the locked position, said slide blocks the catch (5) and in the release position, in which it can be adjusted by means of the pusher nut (8) or the lock cylinder (22), it releases the catch (5). The locking slide (35) can be displaced from the release position to the locked position by pressing on the catch. The locking slide (35) is connected via a lever system (39, 40, 41) to the safety bolt (4) in such a way that the latter is pushed out of the lock when the locking slide (35) is displaced from the release position to the locked position by application of pressure to the catch (5).

Description

Die Erfindung betrifft ein Schloß mit Falle und Sperriegel, die von einem Schließzylinder aus betätigbar sind, und bei dem die Falle auch durch eine Drückernuß einziehbar ist, sowie mit einer Sperre, in deren Raststellung die Falle gegen ein Einschieben gesperrt ist, und die in einer Lösestellung, in die sie mit Hilfe der Drückernuß oder des Schließzylinders verstellbar ist, die Falle freigibt, wobei die Sperre beim Zufallen der mit dem Schloß ausgestatteten Tür aus der Lösestellung in die Raststellung übergeht.The invention relates to a lock with latch and locking bolt, which can be operated from a lock cylinder, and in which the latch can also be retracted by a follower, and with a lock, in the latched position of which the latch is locked against insertion, and which in one Release position, in which it is adjustable with the help of the follower or the lock cylinder, the latch releases, the lock passes when the door equipped with the lock falls from the release position into the locking position.

Ein derartiges Schloß ist aus der US-A-3 672 714 bekannt. Bei diesem Schloß umfaßt die Sperre einen Hebel, daß der in seiner einen, durch einen Auslösetaster bewegten Stellung mit seinem einen in Art eines nasenartigen Vorsprungs ausgebildeten Teil in den Bereich eines Ausschnittes der Falle gelangt und diese damit gegen ein weiteres Einschließen stoppt. Das Schloß gemäß US-A-3 672 714 erfordert damit einen Auslösetaster.Such a lock is known from US-A-3,672,714. In this lock, the lock comprises a lever that in its one position, moved by a trigger button, with its one part designed in the manner of a nose-like projection, reaches the area of a cutout of the trap and thus stops it against further inclusion. The lock according to US-A-3 672 714 therefore requires a trigger button.

Es stellt sich die Aufgabe, das Auslösen einer Sperre beim Zuschlagen der Tür zu vereinfachen, insbesondere auf einen zusätzlichen Taster verzichten zu können.The task is to simplify the triggering of a lock when the door is slammed, in particular to be able to do without an additional button.

Diese Aufgabe wird gelöst durch ein Schloß der eingangs genannten Art, bei dem die Sperre einen Sperrschlitten umfaßt, der durch ein Eindrücken und anschließendes Herausfahren der Falle aus dem Schloßgehäuse aus der Lösestellung in die Fallen-Raststellung überführbar ist.This task is solved by a lock at the beginning mentioned type, in which the lock comprises a locking slide, which can be transferred from the release position into the latched latching position by pressing in and then moving the latch out of the lock housing.

Dazu ist der Sperrschlitten über ein Hebelgestänge mit dem Sperriegel derart verbunden, daß bei Verstellung des Sperrschlittems aus der Lösestellung in die Raststellung bei Eindrücken der Falle der Sperriegel aus dem Schloß verschoben wird.For this purpose, the locking slide is connected to the locking bolt via a lever linkage in such a way that when the locking slide is moved from the release position into the locking position when the latch is pressed, the locking bolt is moved out of the lock.

Für den Fachmann ergeben sich verschiedene Möglichkeiten, ein solches Gestänge auszuführen und eine Wirkverbindug zwischen dem Sperrschlitten und dem Riegel auszugestalten. Es besteht auch die Möglichkeit, den Riegel in verschiedenen Längen auszufahren. Da der Sperrschlitten ein wesentlicher Teil für die Verriegelung der Schloßfalle ist, ist es auch sinnvoll, das Gestänge so auszulegen, daß es bei der Bewegung des Sperrschlittens auch den Riegel in die Schließstellung drückt.There are various possibilities for the person skilled in the art to implement such a linkage and to design an operative connection between the locking slide and the bolt. It is also possible to extend the bolt in different lengths. Since the locking slide is an essential part for locking the lock latch, it also makes sense to design the linkage so that it also pushes the bolt into the closed position when the locking slide moves.

Vorzugsweise werden Sperrschlitten und Hebelgestänge durch eine Feder beaufschlagt, die den Sperrschlitten in die Sperrstellung drückt.The locking slide and lever linkage are preferably acted upon by a spring which presses the locking slide into the locked position.

Ein Schloß 1 gemäß den Figuren 1 und 2 besitzt eine Stulpe 2, einen Schloßkasten 3 mit Schloßboden 3′, einen Riegel 4, eine Falle 5, eine Zuhaltung 6, die von einer Zuhaltungsfeder 57 senkrecht zur Bewegungsrichtung des Riegels 4 beaufschlagt wird. Die obenliegende Zuhaltung 6, der Riegel 4 und eine untenliegende Schloßriegelzuhaltung 53 bilden drei aufeinander gleitende Teile. Weiterhin ist eine Drückernuß 8 vorhanden, die von einer Nußfeder 9 über ein Zwischenstück 10 beaufschlagt wird. Die Drückernuß 8 läuft in einem Arm 29 aus, der mit einer Nase 30 am Fallenschwanz 5˝ angreift, wobei die Falle 5 einen Fallenkopf 5′ und den Fallenschwanz 5˝ besitzt. Die Falle 5 wird durch eine Fallenfeder 11 in Richtung aus der Stulpe 2 heraus beaufschlagt. Der Fallenschwanz 5˝ ist mit einem Langloch 12 versehen, das ein Führungsbolzen 13 durchsetzt. Die Falle 5 besitzt weiterhin eine als Tunnel geformte Ausnehmung 15, die von dem fallenseitigen Ende 16′ eines Wechselhebels 16 durchgriffen wird.A lock 1 according to Figures 1 and 2 has a cuff 2, a lock case 3 with lock base 3 ', a bolt 4, a latch 5, a tumbler 6, which is acted upon by a tumbler spring 57 perpendicular to the direction of movement of the bolt 4. The top tumbler 6, the bolt 4 and a bottom latch bolt tumbler 53 form three sliding parts. There is also a follower 8, which is acted upon by a nut spring 9 via an intermediate piece 10. The follower 8 runs out in an arm 29 which engages with a nose 30 on the trap tail 5 ', the trap 5 has a trap head 5' and the trap tail 5 '. The latch 5 is acted upon by a latch spring 11 in the direction out of the cuff 2. The trap tail 5 'is provided with an elongated hole 12 which passes through a guide pin 13. The trap 5 also has a tunnel-shaped recess 15 which is traversed by the trap end 16 'of a change lever 16.

Der Wechselhebel 16 hat eine etwa J-förmige Gestalt, ist mit einer kurzen Lochführung 17 versehen und dort auf einem Zapfen 18 mit Spiegel gelagert. Der Wechselhebel 16 trägt an seinem unteren verdickten Ende 16˝ über ein Gelenk 19 einen Mitnehmer 20. Gegen das untere Anschlagende 20′ des Mitnehmers 20 stößt der Schließbart 21 eines Schließzylinders 22. Weiterhin besitzt der Mitnehmer 20 eine Langlochführung 23, in der ein Bolzen 24 gleitet, der auf der Zuhaltung 6 befestigt ist.The change lever 16 has an approximately J-shaped shape, is provided with a short hole guide 17 and is mounted there on a pin 18 with a mirror. The change lever 16 carries at its lower thickened end 16˝ via a hinge 19 a driver 20. Against the lower end of the stop 20 'of the driver 20 bumps the lock bit 21 of a lock cylinder 22. Furthermore, the driver 20 has an elongated hole guide 23 in which a bolt 24 slides, which is fixed on the tumbler 6.

Im mittleren Bereich des Wechselhebels 16 ist ferner eine Zuglasche 26 bei 26′ angelenkt, die an ihrem gelenkfernen Ende eine Langlochführung 27 aufweist, in die ein Stehbolzen 28 eingreift, der wiederum mit dem Arm 29 der Drückernuß 8 verbunden ist.In the central region of the change lever 16, a pull tab 26 is also articulated at 26 ', which has at its distal end a slot guide 27 into which a stud 28 engages, which in turn is connected to the arm 29 of the follower 8.

Figur 2 zeigt die unterhalb des Wechselhebels 16 liegende Ebene des Schlosses 1. Die Falle 5 ist an ihrer Unterseite mit einer Aussparung 32 versehen. In diese Aussparung 32 greift im dargestellten Zustand eine Sperrklinke 33 ein, die bei 34 gelagert ist und entsprechend der Schwerkraft aus ihrer Raststellung fällt, wenn sie nicht gehalten ist. Unterhalb der Sperrklinke 33 ist ein Sperrschlitten 35 eingebaut, der innerhalb einer Langlochführung 23, die in den Schloßboden 3′ eingelassen ist, begrenzt horizontal verfahrbar ist.FIG. 2 shows the level of the lock 1 below the change lever 16. The latch 5 is provided with a recess 32 on its underside. In the state shown, a pawl 33 engages in this recess 32, which is mounted at 34 and falls out of its latched position in accordance with the force of gravity when it is not held. Below the pawl 33, a locking slide 35 is installed, which is limited horizontally movable within a slot guide 23, which is embedded in the lock base 3 '.

An seiner Frontseite besitzt der Sperrschlitten 35 eine Auflaufnase 35′, die bei einer äußersten Linksstellung gemäß Figur 2 ein Herabfallen der Sperrklinke 33 verhindert. Der Sperrschlitten 35 besitzt ferner an der der Auflaufnase 35′ gegenüberliegenden Seite eine Anschlagfläche 35˝, die gegen das obere Ende eines Kniehebels 39 drückt. Der Sperrschlitten 35 selbst besitzt ebenfalls eine Sperrvorrichtung, nämlich eine Aussparung 37, die mit einem federbelasteten Schnäpper 38 zusammenwirkt.On its front side, the locking slide 35 has a run-up nose 35 ', which prevents the locking pawl 33 from falling in the extreme left position according to FIG. The locking slide 35 also has on the run-up nose 35 'opposite side a stop surface 35', which presses against the upper end of a toggle lever 39. The locking slide 35 itself also has a locking device, namely a recess 37 which cooperates with a spring-loaded catch 38.

Der Kniehebel 39 bildet mit einem Laschenhebel 40 und einem Eingriffshebel 41 ein dreiteiliges Gestänge, das bei 42′ und 42˝ auf dem Schloßboden 3′ gelagert ist. Auf das freie Kniehebelende 39′ drückt eine Feder 31, die damit sowohl den Sperrschlitten 35 nach links als auch den Riegel 4 nach links drückt, wobei das Gestänge 39, 40, 41 vermittelnd wirkt.The toggle lever 39 forms with a tab lever 40 and an engagement lever 41 a three-part linkage, which is mounted at 42 'and 42' on the lock base 3 '. On the free toggle lever end 39 'presses a spring 31, which thus both the locking slide 35 to the left and presses the bolt 4 to the left, the linkage 39, 40, 41 acting as a mediator.

Das Gestänge 39, 40, 41 ermöglicht das Zusammenwirken von Sperrschlitten 35 und Riegel 4. Letzterer ist hierzu mit einer Ausnehmung 44 versehen, wobei eine Anschlagfläche 44′ auf der linken und eine Anschlagfläche 44˝ auf der rechten Seite gegeben sind und Anschläge für den Eingriffshnebel 41 bilden. Der obere Kniehebel 39 bat etwa eine Winkelform mit 90°-Stellung und kann den Sperrschlitten 35 verstellen. Der Laschenhebel 40 ist am gegenüberliegenden Ende des Kniehebels 39 angebracht. Damit wird er durch das kurze Ende des ebenfalls knieförmig gestalteten Eingriffshebels 41 bewegt, wenn sich letzterer dreht. Umgekehrt drückt das freie Ende des Eingriffshebels den Riegel 4 nach innen, wenn ersterer sich in Gegenrichtung dreht.The linkage 39, 40, 41 enables the interaction of locking slide 35 and bolt 4. The latter is provided with a recess 44, with a stop surface 44 'on the left and a stop surface 44 Anschlag on the right side and stops for the engagement lever 41 form. The upper toggle lever 39 asked for an angular shape with a 90 ° position and can adjust the locking slide 35. The tab lever 40 is attached to the opposite end of the toggle lever 39. He is thus moved by the short end of the knee-shaped engagement lever 41 when the latter rotates. Conversely, the free end of the engagement lever pushes the bolt 4 inward when the former rotates in the opposite direction.

Durch entsprechende Veränderungen des Hebelgestänges 39, 40, 41 ist es möglich, die Ausfahrlänge des Riegels zu variieren.By appropriate changes in the lever linkage 39, 40, 41, it is possible to vary the extension length of the bolt.

Das Ende des Schnäppers 38 ist mit einem aufgesetzten Stehbolzen 43 versehen; einen weiteren Stehbolzen 45 trägt der Sperrschlitten 35. Die genannten Stehnbolzen 43 und 45 werden an ihren Außenflanken tangiert von Auskehlungen 46 und 47, die an der Innenseite des Wechselhebels 16 ausgearbeitet sind und die bei Dreh- und Verschiebebewegung des Wechselhebels die Stehbolzen 43 und 45 in noch zu beschreibender Weise verschieben.The end of the catch 38 is provided with an attached stud 43; the locking slide 35 carries a further stud 45. The studs 43 and 45 mentioned are affected on their outer flanks by grooves 46 and 47, which are worked out on the inside of the change lever 16 and which, when the change lever is rotated and moved, the studs 43 and 45 in move to be described later.

Ein weiterer Funktionskomplex beginnt mit einer an der Drückernuß 8 peripher angebrachten Langlochlasche 50, die bei 50′ an der Drückernuß 8 drehbeweglich befestigt ist. Die Langlochlasche 50 ist über mehr als die Hälfte ihrer Länge mit einem Langloch 51 versehen, in den ein Stehbolzen 52 drehverschiebbar einrastet. Dieser Stehbolzen 52 wiederum steht auf der unteren Schloßriegelzuhaltung 53 auf, die etwa die Form eines Rhombus hat. Die Schloßriegelzuhaltung 53 besitzt an ihrer inneren, vertikalen Außenseite einen Führungsschlitz 54, der entlang eines im Querschnitt quadratischen Führungszapfens 55 gleitet. Auf die Schloßriegelzuhaltung 53 ist ferner in ihrem oberen Bereich ein Rastzapfen 56 aufgesetzt, auf dem von oben das Ende der Feder 57 drückt. Die Schloßriegelzuhaltung 53 läuft in ihrem unteren Teil in eine Zunge 58 aus, die wiederum von innen gegen das Anschlagende 20′ des Mitnehmers 20 anschlägt und demnach bei Anheben des Mitnehmers auch die Schloßriegelzuhaltung 53 anheben läßt.Another complex of functions begins with an elongated hole tab 50 attached to the follower 8, which is fastened at 50 'to the follower 8 so that it can rotate. The elongated hole flap 50 is provided with an elongated hole 51 over more than half of its length, into which a stud 52 snaps in a rotationally displaceable manner. This stud 52 in turn stands on the lower lock bolt tumbler 53, which has approximately the shape of a rhombus. The lock bolt tumbler 53 has on its inner, vertical outer side a guide slot 54 which slides along a guide pin 55 which is square in cross section. On the lock bolt tumbler 53, a locking pin 56 is also placed in its upper region, on which the end of the spring 57 presses from above. The lock bolt tumbler 53 runs in its lower part into a tongue 58, which in turn strikes from the inside against the stop end 20 'of the driver 20 and accordingly can also raise the lock bolt tumbler 53 when the driver is lifted.

Auf dem Riegel 4 liegt die Zuhaltung 6 auf, die mit zwei Rastausnehmungen 60 und 61 versehen ist. Die jeweiligen Tourenstellungen sind durch Einrastungen des Rastzapfens 56 definiert. Die Zuhaltung 6 ist über den Schwanz 4′ des Riegels 4 angeordnet und folgt dessen Konturen. Die Zuhaltung 6 trägt den Bolzen 24, der nach oben und unten ragt. Nach oben bildet er ein Führungselement in der Langlochführung 23, nach unten ragt er in eine weitere Langlochführung 63. Weiterhin ist ein Hauptzapfen 64 vorgesehen, der sowohl die Zuhaltung 6 als auch den Schwanz 4′ des Riegels 4 in entsprechenden Ausnehmungen führt. Beide Teile 6 und 4 sind außerdem an ihrer Unterseite mit einer Tourenausnehmung bzw. einem Tourenanschlag 65 versehen, in die der Schließbart 21 bei Drehung eingreift.The tumbler 6, which is provided with two latching recesses 60 and 61, lies on the bolt 4. The respective tour positions are defined by latching the locking pin 56. The tumbler 6 is arranged over the tail 4 'of the bolt 4 and follows its contours. The tumbler 6 carries the bolt 24 which projects up and down. Upwards it forms a guide element in the slot guide 23, downwards it projects into a further slot guide 63. Furthermore, a main pin 64 is provided, which leads both the tumbler 6 and the tail 4 'of the bolt 4 in corresponding recesses. Both parts 6 and 4 are also provided on their underside with a touring recess or a touring stop 65, in which the cam 21 engages when rotating.

FunktionsbeschreibungFunctional description

Das im folgenden beschriebene Schloß soll mit mechanischen Mitteln folgende Funktionen ausführen können:

1.
Im nicht-geschlossenen Zustand (Riegel 4 innen) soll durch Verdrehen der Drückernuß 8 die Schloßfalle 5 hereingezogen werden.
2.
Im nicht-geschlossenen Zustand soll bei nicht-verdrehter Drückernuß und Anschlagen der Fallenschräge am Fallenkopf 5′ der Riegel 4 eine Tour herausspringen und die Tür verschliessen.
3.
Gleichzeitig mit dem Herausspringen des Riegels 4 soll die Falle gegen ein weiteres Eindrücken gesperrt sein.
4.
Abhängig von der Stellung des Riegels 4 soll dieser zwei oder eine weitere Tour mit Hilfe des Schließbartes 21 herausgedreht werden können.
5.
Der herausgedrehte Riegel soll mit Herunterdrücken der Klinke hereingezogen werden ("Panikfunktion"). Diese vorgenannten, erfindungswesentlichen Funktionen werden nachfolgend anhand der Figuren erläutert.

The lock described below should be able to perform the following functions by mechanical means:
1.
In the non-closed state (bolt 4 inside), by turning the follower 8, the lock latch 5 be drawn in.
2nd
In the non-closed state, when the handle is not rotated and the latch sloping on the latch head 5 ', the latch 4 should jump out and lock the door.
3rd
At the same time as the bolt 4 pops out, the latch should be locked against further pressing.
4th
Depending on the position of the bolt 4, it should be possible to turn out two or another tours with the help of the locking bit 21.
5.
The unscrewed bolt should be pulled in by pressing the latch down ("panic function"). These aforementioned functions essential to the invention are explained below with reference to the figures.

Öffnen der TürOpening the door

Die Figuren 1 bis 4 zeigen jeweils zwei Ebenen des Schlosses bei der Betätigung des Drückers und der damit erfolgenden Drehung der Drückernuß 8. Dabei wird der Arm 29 der Nase 30 des Drückers nach Überlaufen eines Spiels von einigen Millimetern gegen das Ende 5‴ der Falle 5 gedrückt. Während dieser Bewegung wird über die Zuglasche 26 der Wechselhebel 16 im Uhrzeigersinn um um das Gelenk 19 gedreht, wobei die Auskehlungen 46 und 47 _ mit einer gewissen, spielbedingten Verzögerung _ die Stehbolzen 43 und 45 nach rechts drücken. Hierbei drückt der Sperrschlitten 35 nach rechts und gibt die Sperrklinke frei. Diese Bewegung geht der kurz darauf erfolgenden Bewegung der Falle 5 voraus, die damit frei ist und sich nach rechts bewegen kann.FIGS. 1 to 4 each show two levels of the lock when the handle is actuated and the follower nut 8 rotates with it. The arm 29 of the nose 30 of the handle after a play of a few millimeters has passed the end 5 laufen of the latch 5 pressed. During this movement, the change lever 16 is rotated clockwise around the hinge 19 via the pull tab 26, the grooves 46 and 47 pressing the stud bolts 43 and 45 to the right with a certain play-related delay. Here, the locking slide 35 presses to the right and releases the pawl. This movement precedes the movement of the trap 5 which follows shortly thereafter and is free and can move to the right.

Außerdem befindet sich der Riegel 4 in seiner äußersten linken Stellung nach zwei Schließtouren. Der Riegel 4 ist vor der Drehbewegung der Nuß 8 gegen ein Zurückgehen gehalten von den Rastzapfen 56. Durch Verdrehen der Nuß 8 bewegt sich die Langlochlasche nach oben und zieht über den Stehbolzen 52 gegen den Druck der Feder 57 die Schloßriegelzuhalter 53 nach oben. Damit kann der über den Stehbolzen 45 nach rechts gezogene Sperrschlitten den Knieheber 39 im Uhrzeigersinn drehen und das Gestänge 39, 40, 41 so festhalten, das der Eingriffshebel 41 mit dem langen Arm gegen den Riegel 4 drückt. Dabei wird dieser nach innen verstellt. Damit ist die sogenannte "Paniköffnung" vorgenommen.In addition, the bolt 4 is in its extreme left position after two closing tours. Before the rotary movement of the nut 8, the bolt 4 is held against the locking pins 56 from turning back. By turning the nut 8, the elongated hole flap moves upward and pulls the lock bolt retainer 53 upward via the stud bolt 52 against the pressure of the spring 57. Thus, the locking slide pulled to the right over the stud bolt 45 can rotate the knee lifter 39 clockwise and hold the linkage 39, 40, 41 in such a way that the engagement lever 41 presses with the long arm against the bolt 4. This is adjusted inwards. This is the so-called "panic opening".

Freilauf bei offener TürFreewheel with the door open

Steht der Riegel 4 innen, so soll er nicht bewegt werden. Die während der Bewegung der Drücknuß 8 bewegten Elemente üben jetzt keinen Einfluß auf den Riegel aus. Jedoch kann mit Drehung des Schloßbartes 21 der Mitnehmer 20 nach oben und mit ihm der Wechselhebel 16 verdreht werden, so daß das fallenseitige Ende 16′ des Wechselhebels 16 die Falle nach innen drückt. Auch diese Funktion ist bei derartigen Schlössern an sich bekannt.If the bolt 4 is on the inside, it should not be moved. The elements moved during the movement of the nut 8 now have no influence on the bolt. However, with rotation of the lock bit 21 of the driver 20 upwards and with it the change lever 16 can be rotated so that the latch end 16 'of the change lever 16 presses the trap inwards. This function is also known per se in such locks.

Schließen der TürClosing the door

Eine andere Bewegungsfolge stellt sich jedoch ein, wenn die Falle 5 außen steht und durch Anziehen der Tür die Fallenschräge mit einem Anschlag im Türrahmen nach innen gedrückt wird. Damit bewegt sich das fallenseitige Ende 16′ des Wechselhebels 16 im Uhrzeigersinn. Wiederum werden die beiden Stehbolzen 43 und 45 verrückt. Der Schnäpper 38 rastet aus und gibt den Sperrschlitten 35 frei, der sich in Richtung Stulpe 2 bewegt. Dies geht aufgrund der Kraft der Feder 31. Damit wird über die Auflaufnase 35′ die Sperrklinke 33 nach oben gedrückt und rastet beim federbelasteten Zurückfallen der Falle 5 in der Aussparung 32. Die Falle kann demnach nicht mehr mit Drahthaken oder Scheckkarten in das Schloß zurückgedrückt werden.Another sequence of movements occurs, however, if the latch 5 is on the outside and the latch slope is pressed inwards with a stop in the door frame by tightening the door. So that the trap-side end 16 'of the change lever 16 moves clockwise. Again, the two studs 43 and 45 are moved. The catch 38 disengages and releases the locking slide 35, which moves in the direction of cuff 2. This is due to the force of the spring 31. Thus, the pawl 33 is pressed upwards over the nose 35 'and snaps when the spring-loaded fall back of the case 5 in the recess 32. The case can therefore no longer be pressed back into the lock with wire hooks or bank cards .

Bei dieser Bewegung des Sperrschlittens 35 nach links wird auch der Riegel 4 nach links gedrückt. Dies geschieht über das Hebelgestänge 39, 40, 41. Der Riegel 4 wird freigegeben, da der Mitnehmer 20 und sein Anschlagende 20′ die Zunge 58 der Schloßriegelzuhaltung 53 anhebt und damit den Rastzapfen 56 außer Eingriff bringt. Nachdem der Riegel 4 eine Tour nach links gemacht hat, senkt sich die Schloßriegelzuhaltung 53 wieder beim Herausschnellen der Falle 5.During this movement of the locking slide 35 to the left, the bolt 4 is also pressed to the left. This is done via the lever linkage 39, 40, 41. The bolt 4 is released because the driver 20 and its stop end 20 'raises the tongue 58 of the lock bolt tumbler 53 and thus disengages the locking pin 56. After the bolt 4 has made a tour to the left, the lock bolt tumbler 53 lowers again when the latch 5 snaps out.

Der eintourig herausgedrehte Riegel 4 kann auch noch um eine zweite Tour gedreht werden, indem der Schließbart 21 das Riegelende 4′ ergreift und und bei angehobener Schloßriegelzuhaltung 53 ein weiteres Mal dreht. Umgekehrt ist es auch möglich, mit zweitourigem Drehen des Schließbartes 21 im Uhrzeigersinn den Riegel zu öffnen und die Falle 5 über den Mitnehmer 20 und den Wechselhebel 16 in das Schloß zu ziehen, wie es bei derartigen Einsteckschlössern an sich bekannt ist.The one-turn bolt 4 can also be rotated for a second tour by the lock bit 21 grips the bolt end 4 'and rotates a second time with the lock bolt tumbler 53 raised. Conversely, it is also possible to open the bolt with clockwise rotation of the lock bit 21 in a clockwise direction and to pull the latch 5 via the driver 20 and the change lever 16 into the lock, as is known per se with such mortise locks.

Daraus resultiert, daß das vorstehend beschriebene Schloß alle "üblichen" Funktionen eines Schlosses vollzieht; Darüberhinaus kann es jedoch noch weitere Funktionen vollziehen, wie sie zu Beginn der Funktionsbeschreibung erläutert worden sind.As a result, the lock described above performs all the "usual" functions of a lock; In addition, however, it can also perform other functions as explained at the beginning of the functional description.
