Definitions
- a lock for security doors with these features is z. B. from the DE 44 31 925 A1 known. Another lock for security doors will be in the DE 197 38 242 A1 disclosed. The castle after the DE 197 38 242 A1 has a tumbler set of closing tumblers and locking tumblers.
- the Sch physicallyzuiensen can be actuated directly by the key bit and raised on the lock plate out. Thesperrzuroisen are guided in the longitudinal direction of the bolt. In addition to the latch, the lock has a trap.
- the case can only be actuated when the bolt is pushed back, this actuation taking place via a change which can be driven by the tumbler mechanism and via a profile cylinder, which on the one hand is from the outside of the door via a key and on the other hand from the inside of the door via a rotary head is rotatable.
- a disadvantage of the castle after the DE 197 38 242 A1 is that the case is only indirectly secured by the change through the tumbler. Under safety aspects, therefore, the lock according to the DE 197 38 242 A1 still improvable.
- the invention has for its object to provide a bolt and an additional case exhibiting safety lock with improved case protection.
- Such a lock is characterized by the fact that not only the retraction of the bolt, but also the retraction of the case is secured by the existing from Sch Strukturzuroisen and Sperrzuroisen tumbler. Even in the event of unauthorized manipulation of the bolt, the security door would not be finally opened. Rather, this would require further manipulation of the case construction, which was also secured by the full tumbler.
- the lock according to the invention for security doors therefore meets the highest security requirements.
- Preferred embodiments of the lock form the subject of the dependent claims 2 to 15.
- FIGS. 1 and 2 show the castle in an overall view, the only difference between the two figures is that at Fig. 2 some components of the tumbler mechanism arranged at the bottom of the lock have been removed in order to better illustrate its operating principle.
- Fig. 2 are missing Fig. 1 a cover plate 1 of the tumbler and a plurality of behind this cover plate 1 arranged, each associated with each Sch physicallyzuroisen 3 and Sperrzuroisen 4 of the tumbler.
- the lock shown has a total of six to eight Sch consequentzuiensen 3 and correspondingly six to eight Sperrzuiensen.
- Fig. 2 in contrast shows only the lowest and thus last tumbler pair consisting of the Sch effet 3 and Sperrzuiens. 4
- the safety lock can be used by means of a arranged on its front side lockup 5 in a security door and screwed with this.
- a latch 7, and on the other hand a case 8, which is located above the bolt 7.
- Both latch 7 as well as 8 case are mounted horizontally displaceable in the housing 6, including, for example, the bolt 7 is mounted on the bearing journal 9 fixed to the housing.
- the bolt 7 protrudes with its bolt head 10 out of the lock plate 5, so that the security door is closed.
- the case 8 protrudes with a case head 11, which is provided with a conventional case slope, from the lock housing.
- the lock is further provided with an auxiliary latch 12, which is also guided horizontally in the lock housing 6.
- the auxiliary latch 12 is ferderloaded, runs against a corresponding strike plate on the door frame and is thus retained by the strike plate, as far as and as long as the security door assumes its position within the door frame.
- the operation of the security lock is done by pressing the tumbler on a conventional double-bitted key 13, and also on a separate profile cylinder from which in the FIGS. 1 and 2 only the opening 14 is shown for receiving the profile cylinder.
- both the bolt 7 can be withdrawn, as well as, in a second revolution tour of the beard key, the case 8.
- the case 8 can withdraw, and only then , as previously by means of the beard key 13 of the bolt 7 has been completely unlocked by a first revolution tour of the beard key 13.
- the driver pin 15 can this, as soon as the driver 16 is rotated in a clockwise direction, engage in a recess 17 on the lower edge of the bolt 7, and in this case take the latch 7.
- To secure the bolt against pushing back serves a bolt lock 7a with a engaging in a recess of the bolt 7 locking pin 7b.
- About a cam is the bolt lock 7a unlocked by the driver 16.
- the bolt lock 7a locks the latch 7 also, as long as it is completely retracted by the driver 16.
- the driver 16 is mounted on a housing-fixed pivot 16a of the housing.
- the operation of the driver 16 is effected by one of the key bit 13 formed on the key bit profiles, which for this purpose moves against a corresponding contour of the driver 16 when the beard key 13 is rotated in its keyhole.
- the driver 16 surrounds the keyhole, and it is provided in this area with the corresponding drive contours.
- a plate-shaped emergency bolt 18 which is guided exclusively horizontally and thus parallel to the latch 7 in the lock housing 6.
- the emergency bolt 18 on several housing-fixed pin 19, 19 'slide horizontally.
- the movement of the longitudinally displaceable emergency bar 18 is coupled to the movement of the pivotable carrier 16 via a slotted guide 20.
- the slotted guide 20 is composed of a backdrop, i. a contoured slot in the emergency bolt 18, as well as a driver pin 21 which is fixed to the driver 16 and engages the backdrop.
- FIGS. 3a to 3e A comparison of FIGS. 3a to 3e can easily see how, depending on the pivotal position of the driver 16 about its pivot 16a, the driving pin 21 of the driver along the slide guide 20 moves.
- the slide guide 20 has a first portion a, which is arcuate, and a subsequent thereto via a bend second portion b, which extends substantially straight. In the region of the bend, the first section a of the slotted guide passes over at right angles into the second, straight section b.
- the driver 16 attached to the driving pin 21 controls the horizontal movement of the plate 18 by means of this link guide.
- FIGS. 3a to 3e show the functional states A to E.
- a locking member 22 is fixed, which with a molded-on tooth 22 a in a Teeth 23 of Sperrzunes 4 engages. Since the Sperrzunes 4 Although arranged on the emergency bolt 18, but only transversely to the direction of movement of the emergency bolt 18 is movable, and further since the locking member 22 is fixedly secured to the lock housing, can be based on the engagement or disengagement of the tooth 22 a and the teeth 23 well recognize which movement of the emergency bolt 18 executes due to the slotted guide.
- the emergency bolt 18 In the functional position A, the emergency bolt 18 is in its normal position, since the beard key 13 has not yet been rotated, and therefore the driving pin 21 is still in its initial position at the beginning of the first section a of the slotted guide 20.
- the beard key In the functional position B, the beard key has performed about half a turn.
- the driving pin 21 has traveled along the first portion a approximately to half of it, whereby the emergency latch 18 is retracted by the dimension c.
- functional position C which is reached at the end of the first revolution of the beard key 13, the driving pin 21 is located at the transition between the first section a and second section b.
- the emergency bolt 18 has moved back to the left again, the dimension c 'is almost zero.
- the Sperrzuiensen 4 of which, as already mentioned, in the FIGS. 2 to 3e only one Sperrzuiens is shown, each provided with a slot 24, engage in the pins 25, which are an integral part of the Notriegels 18. In this way, each Sperrzunes 4 is guided on the emergency bolt 18, and that transverse to the direction of the emergency bolt 18 and thus also transversely to the direction of movement of the bolt 7.
- Each Sperrzuiens 4 is provided on both vertical edges with barrier structures.
- the locking structure at the left edge is the above-explained teeth 23. In the embodiment are a total of three teeth of the teeth 23 shown, however, another number is possible, thereby changing the number of possible changes of the castle.
- the blocking member 22 facing away from the Sperrzuiens 4 is provided with a locking structure, said locking structure is designed as a recess 30.
- the number of Sch.zuroisen 3 corresponds to the number of Sperzuariaen 4, also Sch.zuaria 3 and Sperrzuaria 4 are each arranged within the same plane.
- the Sch.zuroisen 3 are pivotally mounted on a common pin 19 ', which is fixed to the housing, whereby they perform a substantially vertical (pivoting) movement.
- the same pin 19 ' also serves the horizontal guidance of the emergency bolt 18th
- the lower key bit curve portion 32 b is located on an outwardly resilient tongue 33 Sch conductedzuiens 3.
- the tongue 33 is only at one end over the portion 33 a with the remaining material of Sch Strukturzuiens 3 connected, the other tongue end 33b is free.
- the closing tumbler 3 is provided with a stop 34 which limits the outward movement of the resilient tongue 33.
- the driven by the wrench driver 16 is provided at its end in the pivoting end with a drive lug 40.
- the drive lug 40 is a vertically movable in the lock housing change 41 can be actuated.
- the change includes not only the designed as a slide member 41, but also a rocker 42 which is mounted on a housing-fixed pin 42a. The slider 41 of the change actuates the latch 8 of the lock via the rocker 42 and pulls it back.
- the retraction of the latch occurs during the second tour of the beard key, ie during the transition from operating position C to the functional position E.
- the drive lug 40 of the driver 16 presses on a projection 41a of the change 41, whereby the change 41 pulled down in the housing becomes.
- This movement is implemented by means of the rocker 42 in a return movement of the case 8, as Fig. 2 can be readily recognized.
- the end arm of the rocker 42 engages against a pin 43, which is part of the case 8.
- the slotted guide 46 is effective during the first tour of the beard wrench, in the transition from functional position B to functional position C. After reaching the functional position C and thus the end of the first key rotation, therefore, the blockade of the case 8 is lifted by the locking element 45, so that the case can then be withdrawn by means of the profile cylinder.
- the slotted guide consists of the slotted guide 46 in the bolt 7 and the guide pin 46a of the locking element 45.
- the guide pin 46a is not rigid, but mounted on a longitudinal guide on the locking element 45.
- a longitudinal direction on the locking element 45 mounted spring 46b exerts a permanent spring force on the guide pin 46a in the direction of the bolt closer end of the longitudinal guide, this is the Guide pin 46a spring-loaded on the stop at the end of the longitudinal guide.
- the bolt 7 is also without retraction by the locking element 45 still retractable when the locking element 45 is held by manipulation.
- the trap 8 is formed in two parts with the actual trap base, on which the case head 11 is located, and a latch actuator 8a.
- the basic body of the trap 8 and the trap actuator 8a are guided in parallel, but with a certain play S between them, cf. Fig. 1 , If, therefore, the latch actuator 8a is pulled back over the profile cylinder sitting at 14 or via the rocker 42 and the pin 43, the trap basic body follows only after overcoming the play S.
- actuating cams 50b, 50a are formed both on the latch 12 and on the latch 47.
- Function position A is the starting position.
- Driver 16 and plate 18 are in their normal position, the Sperrzuroisen 4 are locked by the housing-mounted locking member 22.
- the blocking tumblers 4 release from the blocking element 22, as shown in FIG Fig. 3e
- the locking lugs 31 of the closing tumblers also enter the corresponding recesses 30 of the blocking tumblers again at the latest in functional state D. This engagement of the closing tumblers in the blocking tumblers is still maintained in the functional state E.
- the tumbler can be changed.
- the changeover takes place by pulling out the previously used beard key and inserting another beard key with a different beard profile.
- the lock is locked again using the new beard key, it comes at the latest in the functional state D to a new positive connection between the tooth 22a of the locking member 22 and one of the teeth of the teeth 23.
- tooth of the teeth 23 of the tooth 22a retracts depends on Key bar profile of the new beard key. From this point on, the lock is switched to the new beard key, and can only be operated with this new beard key.

Ein Schloß für Sicherheitstüren mit diesen Merkmalen ist z. B. aus der
Nachteilig bei dem Schloß nach der
Der Erfindung liegt die Aufgabe zugrunde, ein einen Riegel sowie eine zusätzliche Falle aufweisendes Sicherheitsschloß mit verbesserter Fallensicherung zu schaffen.The invention has for its object to provide a bolt and an additional case exhibiting safety lock with improved case protection.
Zur Lösung wird bei einem Schloß mit den eingangs genannten Merkmalen vorgeschlagen, daß sämtliche Sperrzuhaltungen auf einem quer zur Bewegungsrichtung der Schließzuhaltungen in dem Schloßgehäuse geführten Notriegel angeordnet sind, daß die Sperrzuhaltungen parallel zur Bewegungsrichtung der Schließzuhaltungen am Notriegel geführt sind, daß Übertragungsmittel zur Umsetzung der Schlüsseldrehung in eine Auslenkung des Notriegels bis zu einer Maximalauslenkung vorgesehen sind, in der die Zuhaltungen miteinander in Eingriff stehen, wobei die Übertragungsmittel dergestalt sind, daß über die erste Schlüsselumdrehung der Eingriff erstmals bewerkstelligt und am Ende der ersten Schlüsselumdrehung wieder aufgehoben wird, und über die zweite Schlüsselumdrehung der Eingriff das zweite Mal bewerkstelligt wird, wobei in einer Ausgangsstellung der Riegel und die Falle aus dem Schloßgehaüse ragen und das Zurückziehen des Riegels und der Falle über das Zuhaltungswerk abgesichert ist, und wobei während der ersten Schlüsselumdrehung die Falle entsperrt wird, jedoch nur der Riegel zurückgezogen wird und während der zweiten Schlüsselumdrehung die Falle zurückgezogen wird.To solve is proposed in a lock with the features mentioned that all Sperrzuhaltungen are arranged on a transversely to the direction of Schließzuhaltungen guided in the lock housing emergency bolts that the Sperrzuhaltungen are performed parallel to the direction of the Schließzuhaltungen on Notriegel that transmission means to implement the key rotation are provided in a deflection of the emergency bolt to a maximum deflection, in which the tumblers are engaged with each other, wherein the transmission means are such that on the first key rotation, the intervention accomplished for the first time and canceled at the end of the first key turn, and on the second Key turn the engagement is accomplished the second time, wherein protrude in a starting position of the latch and the latch from the Schloßgehaüse and the retraction of the bolt and the case about the tumbler safes rt, and wherein during the first key turn the latch is unlocked but only the latch is retracted and during the second key turn the latch is retracted.
Ein solches Schloß zeichnet sich dadurch aus, daß nicht nur das Zurückziehen des Riegels, sondern ebenso das Zurückziehen der Falle über das aus Schließzuhaltungen und Sperrzuhaltungen bestehende Zuhaltungswerk abgesichert ist. Selbst für den Fall einer unbefugten Manipulation des Riegels wäre damit die Sicherheitstür noch nicht endgültig geöffnet. Vielmehr bedürfte es hierzu einer weiteren Manipulation des ebenfalls über das volle Zuhaltungswerk abgesicherten Fallenkonstruktion. Das erfindungsgemäße Schloß für Sicherheitstüren erfüllt daher auch höchste Sicherheitsanforderungen.Such a lock is characterized by the fact that not only the retraction of the bolt, but also the retraction of the case is secured by the existing from Schließzuhaltungen and Sperrzuhaltungen tumbler. Even in the event of unauthorized manipulation of the bolt, the security door would not be finally opened. Rather, this would require further manipulation of the case construction, which was also secured by the full tumbler. The lock according to the invention for security doors therefore meets the highest security requirements.

Die
Das Sicherheitsschloß ist mittels eines an seiner Stirnseite angeordneten Schloßstulps 5 in eine Sicherheitstür einsetzbar und mit dieser verschraubbar. Horizontal innerhalb des quaderförmigen Schloßgehäuses 6 geführt sind einerseits ein Riegel 7, und andererseits eine Falle 8, die sich oberhalb des Riegels 7 befindet. Sowohl Riegel 7 wie auch Falle 8 sind horizontal verschieblich in dem Gehäuse 6 gelagert, wozu z.B. der Riegel 7 auf gehäusefestem Lagerzapfen 9 gelagert ist. In der in den
Das Schloß ist ferner mit einer Hilfsfalle 12 versehen, die ebenfalls horizontal in dem Schloßgehäuse 6 geführt ist. Die Hilfsfalle 12 ist ferderbelastet, läuft gegen ein entsprechendes Schließblech am Türrahmen und wird auf diese Weise von dem Schließblech zurückgehalten, soweit und solange die Sicherheitstür ihre Position innerhalb des Türrahmens einnimmt.The lock is further provided with an
Die Betätigung des Sicherheitsschlosses erfolgt durch Betätigung des Zuhaltungswerks über einen üblichen Doppelbartschlüssel 13, und außerdem über einen separaten Profilzylinder, von dem in den
Das Zurückziehen des Riegels 7 erfolgt über einen Mitnehmerstift 15, der an einem schwenkbar an dem Schloßgehäuse 6 gelagerten Mitnehmer 16 befestigt ist. Der Mitnehmerstift 15 kann hierzu, sobald der Mitnehmer 16 im Uhrzeigersinn gedreht wird, in einer Aussparung 17 an der Unterkante des Riegels 7 eingreifen, und hierbei den Riegel 7 mitnehmen. Zur Sicherung des Riegels gegen Zurückschieben dient eine Riegelsperre 7a mit einem in eine Aussparung des Riegels 7 eingreifenden Sperrstift 7b. Über einen Nocken ist die Riegelsperre 7a durch den Mitnehmer 16 entsperrbar. Die Riegelsperre 7a sperrt den Riegel 7 außerdem, solange dieser durch den Mitnehmer 16 ganz zurückgezogen ist.The retraction of the
Der Mitnehmer 16 ist auf einem gehäusefesten Drehzapfen 16a des Gehäuses gelagert. Die Betätigung des Mitnehmers 16 erfolgt durch eines der an dem Bartschlüssel 13 ausgebildeten Schlüsselbartprofile, welches hierzu gegen eine entsprechende Kontur des Mitnehmers 16 fährt, wenn der Bartschlüssel 13 in seinem Schlüsselloch gedreht wird. Hierzu umgibt der Mitnehmer 16 das Schlüsselloch, und er ist in diesem Bereich mit den entsprechenden Antriebskonturen versehen.The
In einer Ebene oberhalb des Mitnehmers 16 befindet sich ein plattenförmiger Notriegel 18, welcher ausschließlich horizontal und damit parallel zu dem Riegel 7 in dem Schloßgehäuse 6 geführt ist. Hierzu kann der Notriegel 18 auf mehreren gehäusefesten Zapfen 19, 19' horizontal gleiten.In a plane above the
Die Bewegung des längsverschiebbaren Notriegels 18 ist mit der Bewegung des schwenkbaren Mitnehmers 16 über eine Kulissenführung 20 gekoppelt. Die Kulissenführung 20 setzt sich zusammen aus einer Kulisse, d.h. einem konturierten Schlitz im Notriegel 18, sowie aus einem Mitnehmerstift 21, der an dem Mitnehmer 16 befestigt ist und in die Kulisse eingreift.The movement of the longitudinally
Ein Vergleich der
Dies wird besonders deutlich anhand eines Vergleichs der
Die Sperrzuhaltungen 4, von denen, wie bereits erwähnt, in den
Die Anzahl der Schließzuhaltungen 3 entspricht der Anzahl der Sperzuhaltungen 4, außerdem sind Schließzuhaltung 3 und Sperrzuhaltung 4 jeweils innerhalb derselben Ebene angeordnet. Die Schließzuhaltungen 3 sind auf einem gemeinsamen Zapfen 19', der gehäusefest ist, schwenkbar gelagert, wodurch sie eine im wesentlichen vertikale (Schwenk-)bewegung durchführen. Derselbe Zapfen 19' dient außerdem der horizontalen Führung des Notriegels 18.The number of
In üblicher Weise sind die Schließzuhaltungen 3 durch die Bartabschnitte des Doppelbartschlüssels 13 beidseitig betätigbar, wozu jede der Schließzuhaltungen 3 mit einer zentralen Öffnung für den Bart des Bartschlüssels versehen ist, und die Schließzuhaltung oberhalb und unterhalb dieser Öffnung mit individuell gestalteten Schlüsselbart-Kurvenabschnitten 32a, 32b versehen ist, vgl. hierzu
Zur Erzielung einer besonders exakten und verschleißarmen Übertragung der Schließbewegung des Bartschlüssels auf die jeweilige Schließzuhaltung 3 befindet sich der untere Schlüsselbart-Kurvenabschnitt 32b an einer auswärts federnden Zunge 33 der Schließzuhaltung 3. Die Zunge 33 ist nur an ihrem einen Ende über den Abschnitt 33a mit dem übrigen Material der Schließzuhaltung 3 verbunden, das andere Zungenende 33b ist frei. Im Bereich des freien Zungenendes 33b ist die Schließzuhaltung 3 mit einem Anschlag 34 versehen, welcher die Auswärtsbewegung der federnden Zunge 33 begrenzt. Auf diese Weise wird erreicht, daß der Schlüsselbart des Bartschlüssel 13 während der Umdrehung des Schlüssels unterbrechungslos an den Schlüsselbart-Kuvenabschnitten 32a, 32b entlanggleitet. Ungenauigkeiten, auch solche fertigungstechnischer Art, werden vermieden, außerdem wird der Verschleiß an den Schlüsselbart-Kurvenabschnitten durch deren federndes Arbeiten herabgesetzt.To achieve a particularly accurate and low-wear transmission of the closing movement of the beard key on the
Mittels des voranstehend erläuterten Zuhaltungswerkes wird während der ersten Tour des Bartschlüssels nur der Riegel zurückgezogen, und während der zweiten Tour des Bartschlüssels die Falle. Hierzu läßt
Das Zurückziehen der Falle erfolgt während der zweiten Tour des Bartschlüssels, d.h. während des Übergangs von Funktionsstellung C zu der Funktionsstellung E. In diesem Fall drückt die Antriebsnase 40 des Mitnehmers 16 auf einen Vorsprung 41a des Wechsels 41, wodurch der Wechsel 41 in dem Gehäuse heruntergezogen wird. Diese Bewegung wird mittels der Wippe 42 in eine Rückzugsbewegung der Falle 8 umgesetzt, wie
Während der ersten Tour des Bartschlüssels und damit bis einschließlich zu dem Funktionszustand C erfolgt nur ein Zurückziehen des Riegels 7, und nicht der Falle 8. Im Funktionszustand C ist die Falle 8 jedoch entsperrt, und kann in dieser entsperrten Stellung durch Betätigung des in der Ausnehmung 14 sitzenden Profilzylinders 14 zurückgezogen werden. Hierbei greift die Schließnase des Profilzylinders gegen einen Vorsprung 44 der Falle 8 und zieht diese zurück, vgl.
Der Riegel 7 ist ohne Blockade durch das Sperrelement 45 auch dann noch zurückziehbar, wenn das Sperrelement 45 durch Manipulation festgehalten wird.The
Ferner ist es wegen des federnden Kulissenstiftes 46a auch dann möglich den Riegel 7 vorzuschließen ohne daß die Gefahr einer Blockade durch das Sperrelement 45 besteht, wenn sich die Falle 8 noch in ihrer zurückgezogenen Stellung befindet. Auch dies trägt dazu bei, Manipulationen zu verhindern.Furthermore, it is also possible because of the
Die Falle 8 ist zweiteilig ausgebildet mit dem eigentlichen Fallen-Grundkörper, an dem sich auch der Fallenkopf 11 befindet, sowie einem Fallenbetätiger 8a. Grundkörper der Falle 8 und Fallenbetätiger 8a sind parallel geführt, jedoch mit einem gewissen Spiel S zwischen sich, vgl.
Gegen Manipulationen an dem Schloß ist ferner eine zusätzliche Fallensperre 47 (
Die Funktion des in der ersten Tour nur auf den Riegel, und in der zweiten Tour auf die Falle einwirkenden Zuhaltungswerks wird nachfolgend anhand der
Funktionsstellung A ist die Ausgangsstellung. Mitnehmer 16 und Platte 18 sind in ihrer Grundstellung, die Sperrzuhaltungen 4 sind durch das gehäusefeste Sperrorgan 22 verriegelt.Function position A is the starting position.
Im Übergang von Funktionsstellung A zu Funktionsstellung B wird, wie bereits beschrieben, der Notriegel 18 zurückgezogen, außerdem betätigt der Bartschlüssel 13 die Schließzuhaltungen 3 entsprechend dem Schlüsselbartprofil. Hierdurch treten die Sperrnasen 31 der Schließzuhaltungen 3 in die entsprechenden Ausnehmungen 30 der Sperrzuhaltungen 4 formschlüssig ein. Der so erzeugte formschlüssige Eingriff ist jedoch nicht von Dauer, vielmehr verlassen die Sperrnasen 31 während des Übergangs zur nächstfolgenden Funktionsstellung C die Ausnehmungen 30 wieder, wie
Während der Funktionsstellungen A, B, C kommt es zu keinerlei Veränderung an den Sperrzuhaltungen 4. Deren Verzahnung behält ihre relative Lage zu dem Sperrorgan 22 bei.During the functional positions A, B, C, there is no change to the locking
Während der zweiten Tour jedoch, d.h. bei Durchlaufen des Funktionszustandes D und bis zum Erreichen des Funktionszustandes E, lösen sich die Sperrzuhaltungen 4 von dem Sperrorgan 22, wie dies in
Im Funktionszustand E läßt sich das Zuhaltungswerk umstellen. Die Umstellung erfolgt, indem der bisher verwendete Bartschlüssel herausgezogen wird, und ein anderer Bartschlüssel mit anderem Bartprofil eingesetzt wird. Sobald unter Verwendung des neuen Bartschlüssels das Schloß wieder zugeschlossen wird, kommt es spätestens im Funktionszustand D zu einem erneuten Formschluß zwischen dem Zahn 22a des Sperrorgans 22 und einem der Zähne der Verzahnung 23. In welchen Zahn der Verzahnung 23 der Zahn 22a einfährt, hängt vom Schlüsselbartprofil des neuen Bartschlüssels ab. Von diesem Zeitpunkt an ist das Schloß auf den neuen Bartschlüssel umgestellt, und läßt sich auch nur noch mit diesem neuen Bartschlüssel betätigen.In functional state E, the tumbler can be changed. The changeover takes place by pulling out the previously used beard key and inserting another beard key with a different beard profile. As soon as the lock is locked again using the new beard key, it comes at the latest in the functional state D to a new positive connection between the
Entscheidend für die beschriebene Möglichkeit einer Umstellung des Schlosses auf einen anderen Schlüssel ist daher, daß während der ersten Tour des Schlüssels die Schließzuhaltung zwar in die Sperrzuhaltung einfährt, dieser Eingriff jedoch nur vorübergehender Natur ist, und er am Ende der ersten Tour bereits wieder aufgehoben ist. Erst am Ende der zweiten Tour des Schlüssels, bei welcher die Falle zurückgezogen wird, bleiben Schließzuhaltung und Sperrzuhaltung in gegenseitigem Formschluß.Decisive for the described possibility of a change of the lock on another key is therefore that during the first tour of the key, the closing lock retracts though in the Sperrzuhaltung, but this intervention is only temporary nature, and he is already repealed at the end of the first tour , Only at the end of the second tour of the key, in which the case is withdrawn, remain Schließzuhaltung and Sperrzuhaltung in mutual positive.
