Stand der TechnikState of the art

Aus der den Oberbegriff des Anspruchs 1 bildenden US-Patentschrift 3 053 071 ist eine Sperr-und Öffnungsgeheimnis-Neueinstellungsvorrichtung für Permutationsschlösser mit mehreren Einstellscheiben bekannt geworden, bei welcher den Einstellscheiben axial verlagerbare Sperrscheiben zugeordnet sind. Deren Eingriff in die Einstellscheiben ist zur Neueinstellung des Öffnungsgeheimnisses aufhebbar. Jede der Sperrscheiben weist umfangseitig einen radialen Schlitz auf, der sich bei richtig eingestelltem Öffnungsgeheimnis in Gegenüberlage zu einem Sperrstift einer Riegelplatte befindet. Diese Riegelplatte wird von aussen über eine Handhabe betätigt, wobei die Tast- oder Sperrstifte in die Schlitze der Sperrscheiben eintreten. Zur Neueinstellung des Öffnungsgeheimnisses ist eine von aussen betätigbare Steuerplatte vorgesehen, die über kugelförmige Druckteile den Sperreingriff zwischen den Sperrscheiben und den Einstellscheiben aufhebt.US Pat. No. 3,053,071, which forms the preamble of claim 1, discloses a locking and opening secret re-adjustment device for permutation locks with a plurality of shims, in which axially displaceable locking disks are assigned to the shims. Their intervention in the shims can be canceled to reset the opening secret. Each of the locking disks has a radial slot on the circumference, which, when the opening secret is set correctly, is opposite to a locking pin of a locking plate. This locking plate is actuated from the outside via a handle, the feeler or locking pins entering the slots in the locking disks. To reset the opening secret, an externally operable control plate is provided, which cancels the locking engagement between the locking disks and the adjusting disks via spherical pressure parts.

In der Patentschrift DE 2918235 wird ein aus dem obengenannten Patent weiterentwickeltes Permutationsschloss offenbart, das bei der Neueinstellungsvorrichtung auf eine besondere Steuerplatte verzichtet. Dort ist die Riegelplatte so ausgebildet, dass sie neben der Abtastfunktion zugleich die eines Sperrteiles der Sperr- und Öffnungsgeheimnis-Neueinstellvorrichtung ausübt. Die Riegelplatte ist so ausgestanzt, dass sich bei Untergriff möglichst grossflächige, sichelförmige, erhabene Sperrzonen ergeben. Die Riegelplatte weist drei Sperrfinger auf, die bei richtiger Einstellung in die Aussparungen der drei Sperrscheiben eingreifen. Da die Achsen der Sperrscheiben auf einer Geraden liegen und die Riegelplatte um einen Achszapfen schwenkbar ist, der einen bestimmten Abstand von dieser Geraden aufweist, sind die Drehkreise der Sperrfinger ganz unterschiedlich gross. Wenn man bei verriegeltem Schloss die Handhabe leicht belastet und eine Fallenscheibe verstellt, gleitet der Sperrfinger auf der Sperrscheibe. Mit etwas Fingerspitzengefühl kann man die Lage der Aussparungen ertasten. Durch Wiederholung des Vorganges mit den nächsten Scheiben lässt sich das Schlossgeheimnis erfühlen, so dass es ohne jede Beschädigung von Unbefugten geöffnet und ohne Hinterlassung von Spuren wieder verschlossen werden kann.Patent specification DE 2918235 discloses a permutation lock further developed from the above-mentioned patent, which dispenses with a special control plate in the readjustment device. There, the locking plate is designed such that, in addition to the scanning function, it also exercises that of a locking part of the locking and opening secret reset device. The locking plate is punched out in such a way that, when gripped, crescent-shaped, raised blocking zones are formed which are as large as possible. The locking plate has three locking fingers that engage in the recesses of the three locking washers when set correctly. Since the axes of the locking disks lie on a straight line and the locking plate can be pivoted about an axle journal which is at a certain distance from this straight line, the turning circles of the locking fingers are of very different sizes. If the handle is lightly loaded and a latch disc is adjusted while the lock is locked, the locking finger slides on the locking disc. With a bit of tact, you can feel the position of the recesses. The lock secret can be felt by repeating the process with the next panes, so that it can be opened without any damage by unauthorized persons and locked again without leaving any traces.

In Fig. 2 ist der vorzugsweise im Druckgussverfahren hergestellte Schlosskasten 10 dargestellt, der in symmetrischer Anordnung Führungsbolzenpaare 11-13 aufweist, die mit einem Gewindeloch versehen sind. Weitere in der Schlossachse A-B liegende Stehbolzen 14,15,16,17 dienen als Führungsdorne für den Riegelbetätigungsgriff und die Kodierungsknöpfe. Mit 18 ist ein Führungsdorn für den Umstellschlüssel bezeichnet, mit 19a und 19b ein angeformtes Quaderpaar mit Gewindeloch. In den vier Ecken des Schlosskastens 10 sind Befestigungslöcher angeordnet, von denen die Löcher 10a und 10b sichtbar sind.2 shows the lock case 10, which is preferably produced by the die-casting process and which, in a symmetrical arrangement, has pairs of guide bolts 11-13 which are provided with a threaded hole. Further stud bolts 14, 15, 16, 17 lying in the lock axis A-B serve as guide pins for the bolt actuation handle and the coding buttons. With 18 a guide mandrel for the change key is designated, with 19a and 19b a molded pair of cuboids with a threaded hole. Fastening holes are arranged in the four corners of the lock case 10, of which the holes 10a and 10b are visible.

Die Riegelplatte 20 nach Fig. 3 kann ebenso wie der Schlosskasten aus einer giessbaren Legierung hergestellt werden. Am linken Ende ist der eigentliche Riegel 20a angeformt. Die Platte weist eine Reihe von Langlöchern auf, die über die Bolzen 11-13 die Riegelplatte genau führen. Mit 21, 22, 23 sind in der Schlossachse A-B liegende quaderförmige Sperrstifte bezeichnet, die in radiale Schlitze 30a, 31 a, 32a der Sperrscheiben 30, 31, 32 (Fig. 4) eingreifen. Weitere quaderförmige Sperrstifte 24, 25, 26 greifen in die Zuhaltungen 50, 51, 52 nach Fig. 6 ein.The locking plate 20 according to FIG. 3, like the lock case, can be made from a castable alloy. The actual latch 20a is formed on the left end. The plate has a series of elongated holes which precisely guide the locking plate via the bolts 11-13. With 21, 22, 23 block-shaped locking pins lying in the lock axis A-B are designated, which engage in radial slots 30a, 31a, 32a of the locking disks 30, 31, 32 (FIG. 4). Further cuboid locking pins 24, 25, 26 engage in the tumblers 50, 51, 52 according to FIG. 6.

Auf der Riegelplatte 20 liegt eine Exzenterscheibe 27, die auf dem Dorn 14 gelagert ist und die die Riegelplatte über den Stift 20b mitnimmt. Die Exzenterscheibe 27 wird über den Stift 27a von einem nicht dargestellten Riegelbetätigungsgriff angetrieben.On the locking plate 20 there is an eccentric disc 27 which is mounted on the mandrel 14 and which takes the locking plate with it via the pin 20b. The eccentric disc 27 is driven via the pin 27a by a bolt actuating handle, not shown.

Die Riegelplatte 20 weist in dem mittleren Bereich 20c eine rechteckige Vertiefung auf, die die Sperrscheiben 30, 31, 32 nach Fig.4 aufnimmt. Jede dieser Sperrscheiben ist an der Unterseite mit einer radialen Nut 30a, 31a, 32a versehen, in die bei geöffnetem Schloss die Sperrstifte 21-23 eingreifen. An der Oberseite ist eine diametrale Nut 30b, 31 b, 32b vorgesehen, die die Sperrschieber 33, 34, 35 aufnimmt. Diese Schieber tragen an ihrem rechten Ende Sperrzähne 33a, 34a, 35a.The locking plate 20 has a rectangular recess in the central area 20c, which receives the locking disks 30, 31, 32 according to FIG. Each of these locking disks is provided on the underside with a radial groove 30a, 31a, 32a, into which the locking pins 21-23 engage when the lock is open. A diametrical groove 30b, 31b, 32b is provided on the upper side, which receives the locking slides 33, 34, 35. These sliders have ratchet teeth 33a, 34a, 35a at their right end.

Fig. 5 zeigt einen Umstellschieber 40, der drei kreisförmige Aussparungen 40a, 40b, 40c aufweist. Der Kreisdurchmesser entspricht dem Durchmesser der Teile 30-35. Der Schieber liegt jedoch derart über den Sperrscheiben, dass er bei Verstellung in Richtung der Schlossachse A-B lediglich die Sperrschieber 33-35 mitnimmt. Der Umstellschieber 40 wird mit Hilfe der Langlöcher 41-46 geführt. Seine Verstellung erfolgt mit Hilfe eines Stiftes 91 oder eines Umstellschlüssels 90, der in die Bartaussparung 47 eingreift.5 shows a change-over slide 40 which has three circular cutouts 40a, 40b, 40c. The circle diameter corresponds to the diameter of the parts 30-35. However, the slide lies over the locking disks in such a way that it only takes the locking slides 33-35 with it in the direction of the lock axis A-B. The change-over slide 40 is guided with the help of the elongated holes 41-46. It is adjusted with the aid of a pin 91 or a change key 90 which engages in the bar recess 47.

Fig. 6 zeigt die Zuhaltungen 50, 51, 52, die über Langlöcherpaare 50a, 50b, 51 a, 51 b, 52a, 52b und die Bolzen 11-13 derart geführt sind, dass sie quer zur Schlossachse A-B verschoben werden können. Jede Zuhaltung weist eine leicht ovale Aussparung 50c, 51c, 52c auf, die am oberen Ende in einen Rastzahn 50d, 51 d, 52d übergeht.Fig. 6 shows the tumblers 50, 51, 52, which are guided over pairs of elongated holes 50a, 50b, 51a, 51b, 52a, 52b and the bolts 11-13 such that they can be moved transversely to the lock axis A-B. Each tumbler has a slightly oval recess 50c, 51c, 52c, which at the upper end merges into a locking tooth 50d, 51d, 52d.

In Fig. 7 sind Zahnscheiben 60,61,62 angedeutet, die über nicht dargestellte Hohlwellen durch den in Fig. 8 dargestellten Schlossdeckel 70 hindurch mit den Kodierungsknöpfen 80, 81, 82 nach Fig. 9 verbunden sind. Die Hohlwellen umfassen die Führungsdorne 15, 16, 17. Die Teile sind in ihrer Höhe so aufeinander abgestimmt, dass die Verzahnung der Scheiben 60, 61, 62 sowohl in die Sperrzähne 33a, 34a, 35a als auch in die Rastzähne 50d, 51d, 52d eingreift. Die Zuhaltungen 50-52 werden durch Schraubenfedern 53, 54, 55 in Eingriff mit den Zahnscheiben 60,61,62 gehalten.7, toothed disks 60, 61, 62 are indicated, which are connected to the coding buttons 80, 81, 82 according to FIG. 9 via hollow shafts, not shown, through the lock cover 70 shown in FIG. 8. The hollow shafts include the guide pins 15, 16, 17. The height of the parts is matched to one another in such a way that the toothing of the disks 60, 61, 62 both in the locking teeth 33a, 34a, 35a and in the locking teeth 50d, 51d, 52d intervenes. The tumblers 50-52 are held in engagement with the toothed disks 60, 61, 62 by coil springs 53, 54, 55.

Fig. 10 stellt eine Draufsicht auf das teilweise montierte Schloss dar. Der Riegel 20a nimmt die Schliessstellung ein. Unter dem Riegel liegt ein quer zur Schlossachse A-B beweglicher Rastschieber 83, der über eine Schraubenfeder 84, einen Stift 85 und eine Steuerkurve der Riegelplatte 20 bewirkt, dass der Riegel eine von zwei stabilen Endlagen einnimmt.10 shows a top view of the partially assembled lock. The bolt 20a assumes the closed position. Under the bolt is a locking slide 83 movable transversely to the lock axis A-B, which via a coil spring 84, a pin 85 and a control curve of the locking plate 20 causes the bolt to assume one of two stable end positions.

Ein Steuerschieber 86 (s. Fig. 14-16) wird vom Bart 90a eines Umstellschlüssels 90 betätigt. Dieser Schieber trägt einen quaderförmigen Sperrstift 88, der durch eine Schraubenfeder 89 in der gezeichneten Normalposition gehalten wird. In dieser Position ist sowohl der Umstellschieber 40 als auch der Steuerschieber 86 blockiert, weil der Stift 88 an der Riegelplatte 20 anliegt.A control slide 86 (see FIGS. 14-16) is actuated by the beard 90a of a changeover key 90. This slide carries a cuboid locking pin 88, which is held by a coil spring 89 in the normal position shown. In this position, both the changeover slide 40 and the control slide 86 are blocked because the pin 88 abuts the locking plate 20.

Fig. 11 zeigt die Lage der montierten Teile nach Fig. 10. Man erkennt die Schieber 83 und 86 zwischen dem Boden des Kastens 10 und der Riegelplatte 20. Der Umstellschlüssel ist mit 90 bezeichnet. In der gezeigten Schliessstellung stehen die Sperrstifte 21-23 ausserhalb der Sperrscheiben 30-32. Weiterhin liegt der Sperrstift 24 ausserhalb des Schlitzes 50e der Zuhaltung 50. In der Schliessstellung können daher die Kodierungsknöpfe 80-82 beliebig umgestellt werden, um die Kombination zu verwerfen. Beim Versuch, den Riegel zurückzuschieben, stossen die Sperrstifte 21-23 gegen die Sperrscheiben 30-32. Bei erneuter Wahl der Kombination nehmen die Sperrschieber 33-35 wiederum die Lage nach Fig. 4 ein, in der der Riegel zurückschiebbar ist.Fig. 11 shows the position of the assembled parts according to Fig. 10. You can see the slider 83 and 86 between the bottom of the box 10 and the locking plate 20. The change key is designated 90. In the closed position shown, the locking pins 21-23 are outside the locking disks 30-32. Furthermore, the locking pin 24 lies outside the slot 50e of the tumbler 50. In the closed position, the coding buttons 80-82 can therefore be changed over as desired in order to reject the combination. When trying to push the latch back, the locking pins 21-23 hit the locking washers 30-32. When the combination is selected again, the locking slides 33-35 again assume the position according to FIG. 4 in which the bolt can be pushed back.

Nur in der Offenstellung entsprechend Fig. 12 und 13 kann die einmal eingestellte Kombination geändert werden. In dieser Stellung kann der Sperrstift 88 in eine Aussparung 20d der Riegelplatte eingreifen, so dass der Riegel während des Umstellvorganges blockiert ist. Weiterhin sind in der Offenstellung über die Stifte 21-23 die Sperrscheiben 30-32 und über die Sperrzähne 33a-35a die Zahnscheiben und damit die Kodierungsknöpfe blockiert. Die Kodierungsknöpfe zeigen also die alte Kombination, z.B. ABC, an. Abweichend von der Zeichnung können die Sperrzähne 33a-35a durch mechanisch stabilere Sperrsegmente ersetzt werden.The combination once set can only be changed in the open position according to FIGS. 12 and 13. In this position, the locking pin 88 can engage in a recess 20d of the locking plate, so that the locking bar is blocked during the changeover process. Furthermore, in the open position, the locking disks 30-32 are blocked by the pins 21-23 and the toothed disks and thus the coding buttons are blocked by the locking teeth 33a-35a. The coding buttons therefore show the old combination, e.g. ABC. The ratchet teeth can deviate from the drawing 33a-35a can be replaced by mechanically more stable locking segments.

Der Code kann vom berechtigten Benutzer des Wertbehälters geändert werden, nachdem er das Schloss entriegelt hat. Zur Umstellung muss zunächst der Steuerschieber 86 nach unten geschoben werden, bis der mit ihm verbundene Sperrstift 88 den Umstellschieber 40 freigibt. Der Umstellschieber wird dann mit Hilfe der Schraubenfeder 93 in die rechte Endlage gezogen.The code can be changed by the authorized user of the safe after he has unlocked the lock. For the changeover, the control slide 86 must first be pushed down until the locking pin 88 connected to it releases the changeover slide 40. The changeover slide is then pulled into the right end position with the aid of the coil spring 93.

Die Zuhaltungen 50-52 bewirken über die Zähne 50d-52d eine «Digitalisierung» der Bewegung der Kodierungsknöpfe. Jede Zuhaltung wird bei Verstellung des zugehörigen Kodierungsknopfes auf- und abbewegt und rastet in die Verzahnung ein, so dass der Steuerkanal, z.B. 50e, den Stift 24 bei der Riegelbewegung passieren lässt. Sollte aber dennoch einmal eine Zuhaltung auf einer Zahnspitze, also zwischen zwei Kodierungspositionen hängen bleiben, ist über den Steuerschlitz die Riegelbewegung blockiert. Umgekehrt können die Kodierungsknöpfe nicht verstellt werden, wenn der Riegel in einer Zwischenstellung hängen bleiben sollte.The tumblers 50-52 cause a "digitization" of the movement of the coding buttons via the teeth 50d-52d. Each tumbler is moved up and down when the associated coding button is adjusted and engages in the toothing so that the control channel, e.g. 50e, the pin 24 can pass during the bolt movement. However, if a tumbler should nevertheless get stuck on one tooth tip, i.e. between two coding positions, the locking movement is blocked via the control slot. Conversely, the coding buttons cannot be adjusted if the latch is caught in an intermediate position.

Alle beschriebenen gegenseitigen Verriegelungen machen das Schloss insofern narrensicher, als es auch durch Falschbehandlung nicht in einer Position gebracht werden kann, in der nur noch Abhilfe durch Aufbohren möglich ist.All of the mutual interlocks described make the lock foolproof insofar as it cannot be brought into a position by incorrect handling, in which only remedial action is possible by drilling.

Grundsätzlich wird das Schloss in einer von zwei Versionen ausgeliefert. Die Version 1 wird für Bauerbenutzer im Bank- und Privatbereich eingesetzt, die Version 2 für häufig wechselnde Benutzer in Hotels.Basically, the lock is delivered in one of two versions. Version 1 is used for farmer users in the banking and private sector, version 2 for frequently changing users in hotels.

In der Version 1 wird der Steuerschieber 86 mit Hilfe eines in Fig. 16 dargestellten Stiftes 92 bewegt, der an der Rückseite des Schiebers 86 befestigt ist und durch den Schlosskasten hindurch in den Wertbehälter hineinragt. Ein weiterer Stift 91, der ebenfalls rückseitig aus dem Schlosskasten herausragt, ist am Umstellschieber 40 befestigt.In version 1, the control slide 86 is moved with the aid of a pin 92 shown in FIG. 16, which is fastened to the rear of the slide 86 and projects through the lock case into the security container. Another pin 91, which also protrudes from the rear of the lock case, is attached to the change-over slide 40.

Die Stellungen der Schieber 40 und 86 sind in Fig. 12 und 13 dargestellt.The positions of the slides 40 and 86 are shown in FIGS. 12 and 13.

Die Winkelform der Aussparung 48 bewirkt, dass der Steuerschieber 86 blockiert ist, wenn der Umstellschieber 40 die Umstellposition einnimmt. Der Umstellschieber 40 nimmt über seine Aussparungen 40a, 40b, 40c (Fig. 5) die Sperrschieber 33, 34, 35 (Fig. 4) mit, so dass die Zahnscheiben 60, 61, 62 (Fig. 7) von den Sperrzähnen 33a, 34a, 35a entkuppelt werden. Folglich können nun die Kodierungsknöpfe 80, 81, 82 von der alten Kombination, z.B. ABC, auf eine neue, z.B. XYZ, umgestellt werden. Wenn man jetzt mit dem Stift 91 den Umstellschieber zurückholt, drückt die Feder 89 den Steuerschieber 86 nach oben, und der Umstellschieber 40 wird erneut arretiert. Man klann jetzt, evtl. nach einer Probeschliessung bei offener Tür, den Behälter schliessen, den Riegel einlegen und die Kombination verwerfen.The angular shape of the recess 48 causes the control slide 86 to be blocked when the changeover slide 40 assumes the changeover position. The change-over slide 40 takes the locking slides 33, 34, 35 (FIG. 4) via its recesses 40a, 40b, 40c (FIG. 5), so that the toothed disks 60, 61, 62 (FIG. 7) are removed from the locking teeth 33a, 34a, 35a are uncoupled. As a result, the coding buttons 80, 81, 82 of the old combination, e.g. ABC, to a new one, e.g. XYZ. If you now retract the change-over slide with the pin 91, the spring 89 presses the control slide 86 upward, and the change-over slide 40 is locked again. Now you can close the container, insert the bolt and discard the combination, possibly after a test closing with the door open.

Die Version 2 wird. vorwiegend in Hotelzimmern eingesetzt, wo besondere Bedingungen herrschen. Hier soll einerseits der Hotelgast in der Lage sein, unabhängig vom Hotelpersonal eine bestimmte Kombination einzustellen. Andererseits aber muss sichergestellt werden, dass der Behälter bei der Abreise des Gastes entriegelt ist, weil sonst umfangreiche Nachforschungen erforderlich werden und der Behälter wochenlang blockiert sein könnte. Nicht selten ist der Gast nicht mehr zu erreichen, oder er hat die Kombination vergessen, so dass nur noch die partielle Zerstörung des Schlosses als Ausweg bleibt.Version 2 will. mainly used in hotel rooms where special conditions prevail. On the one hand, the hotel guest should be able to set a certain combination independently of the hotel staff. On the other hand, it must be ensured that the container is unlocked when the guest leaves, because otherwise extensive research will be required and the container could be blocked for weeks. It is not infrequent that the guest can no longer be reached, or he has forgotten the combination, so that only the partial destruction of the castle remains as a way out.

Um alle diese Probleme zu umgehen, wird das Schloss in der sogenannten «Hotelversion» ohne die Stifte 91, 92 und statt dessen mit einem Umstellschlüssel 90 ausgeliefert, der nur bei entsperrtem Schloss und in der Umstellposition des Schiebers 40 in das Schlüsselloch 71 eingeführt und abgezogen werden kann. Wenn also der Gast angehalten wird, den Umstellschlüssel bei der Abreise abzugeben, ist die Gewähr dafür gegeben, dass das Schloss vom nächsten Gast sofort neu kodiert und der Wertbehälter benutzt werden kann.In order to avoid all these problems, the lock is delivered in the so-called “hotel version” without the pins 91, 92 and instead with a change key 90, which is inserted and removed into the key hole 71 only when the lock is unlocked and in the change position of the slide 40 can be. So if the guest is asked to hand in the changeover key on departure, the guarantee is given that the lock can be re-encoded by the next guest and the safe can be used.

Der Schlüssel 90 greift sowohl in eine Schlüsselbartaussparung 87 des Schiebers 86 als auch in die Schlüsselbartaussparung 47 des Umstellschiebers 40 ein. In der Fig. 14 ist die Normalposition, in der Fig. 15 die Umstellposition dargestellt. Fig. 16 zeigt den Schieber von der Seite. Da das Schlüsselloch 71 senkrecht zur Schlossachse A-B angeordnet ist, kann der Schlüssel nur in der Umstellposition nach Fig. 15 abgezogen werden. Weil aber in dieser Stellung der Riegel 20a blokkiert ist, kann der Behälter nur auf- und zugeschlossen werden, wenn der Umstellschlüssel 90 steckt und die Stellung nach Fig. 14 einnimmt. Die beschriebene Lösung hat den grossen Vorteil, dass das Hotelpersonal von der Rezeption aus durch Entgegennahme des Umstellschlüssels die Offenstellung des im Zimmer oder Tresorraum untergebrachten Wertbehälters kontrollieren kann.The key 90 engages both in a key bit cutout 87 in the slide 86 and in the key bit cutout 47 in the changeover slide 40. 14 shows the normal position and FIG. 15 shows the changeover position. Fig. 16 shows the slider from the side. Since the keyhole 71 is arranged perpendicular to the lock axis A-B, the key can only be removed in the changeover position according to FIG. 15. However, because in this position the bolt 20a is blocked, the container can only be opened and closed when the change key 90 is inserted and in the position shown in FIG. 14. The solution described has the great advantage that the hotel staff can check from the reception by accepting the changeover key that the safe is open in the room or vault.

In der Fertigung weisen beide Schlossversionen weitgehend identische Bauteile auf. Vor allem die Stanzteile sind gleichartig ausgebildet. Um Manipulationen zu verhindern, empfiehlt es sich jedoch, in der Version 2 im Schlossgehäuse keine Langlöcher für die Umstellstifte vorzusehen. In dieser Ausführung werden an die Schieber 40 und 86 keine Stifte angenietet.Both lock versions have largely identical components in production. The stamped parts in particular are of the same design. To prevent tampering, it is recommended, however, that version 2 of the lock housing does not provide any elongated holes for the changeover pins. In this embodiment, no pins are riveted to the sliders 40 and 86.

In Fig. 17 ist in Teildarstellung als besondere Bauart ein Basküleschloss gezeichnet. Die Seitenwände des Schlosskastens 10 sind mit Aussparungen 10c, 10d versehen, in denen Baskülestangen 94, 95 geführt sind. Sie werden über schräggestellte Langlöcher, z.B. 94a, und einen auf der Riegelplatte 20 sitzenden Treibdorn 20e bewegt. Da die Riegelplatte 20 unter Benutzung des Führungsdornes 14 mittels einer besonderen Handhabe verstellt wird, bereitet es im Gegensatz zu Einknopfkombinationsschlössern keinerlei Probleme, das zusätzliche Drehmoment zu übertragen.In Fig. 17 a partial lock is drawn as a special design in partial representation. The side walls of the lock case 10 are provided with cutouts 10c, 10d, in which the base rods 94, 95 are guided. They are slanted through oblong holes, e.g. 94a, and a driving mandrel 20e seated on the locking plate 20 is moved. Since the locking plate 20 is adjusted using the guide pin 14 by means of a special handle, in contrast to single-button combination locks, it does not cause any problems to transmit the additional torque.

Eine andere Ausgestaltung des Schlosses ist in Fig. 18 dargestellt. Sie zeigt den rechten Teil des Schlosskastens 10, auf dessen dem Riegel abgekehrter Stirnwand ein Mikroschalter 96 aufgesetzt ist. Der Stössel 96a dieses Schalters tastet die hintere Kante des Umstellschiebers 40 ab. In dieser Ausführungsform wird ein Kontakt betätigt, wenn der Schieber in Umstellposition ist, wenn also die Safetür offen ist. Man kann z.B. in der Hotelversion des Schlosses die Schlossstellung in der Rezeption anzeigen, um sicherzustellen, dass die Wertbehältertür bei der Abreise des Gastes offen ist.Another embodiment of the lock is shown in Fig. 18. It shows the right part of the lock case 10, on which the bolt abge a microswitch 96 is placed on the opposite end wall. The plunger 96a of this switch scans the rear edge of the changeover slide 40. In this embodiment, a contact is actuated when the slide is in the changeover position, that is, when the safe door is open. In the hotel version of the lock, for example, you can display the lock position in the reception to ensure that the safe door is open when the guest leaves.

Die Bedienungsanleitung für beide Versionen ist zusammengefasst folgende:The operating instructions for both versions are summarized as follows:

Die Öffnung des Schlosses erfolgt durch Einstellung der Kombination an den Kodierungsknöpfen und Rechtsdrehung des Riegelbetätigungsgriffes.The lock is opened by adjusting the combination on the coding knobs and turning the bolt handle to the right.

Zum Schliessen wird der Riegelbetätigungsgriff nach links gedreht und die Kombination durch Verstellen aller Kodierungsknöpfe verworfen.To close the bolt actuation handle is turned to the left and the combination is discarded by adjusting all coding buttons.

Zum Einstellen einer neuen Zahlenkombination wird in der Version 1 der Steuerschieberstift 92 nach unten geschoben, so dass der Umstellschieber umspringt und die Kodierungsknöpfe zur Neueinstellung freigibt. Anschliessend wird der Umstellschieber mit Hilfe des Stiftes 91 zurückgezogen.In order to set a new combination of numbers, the control slide pin 92 is pushed down in version 1, so that the change-over slide jumps around and releases the coding buttons for readjustment. The changeover slide is then withdrawn with the aid of the pin 91.

Bei der für den Hotelbereich bestimmten Version 2 dreht man den Umstellschlüssel 90 um etwa 90° nach links, stellt die neue Kombination ein und dreht den Schlüssel wieder nach rechts. In der Umstellposition kann der Schlüssel vom bisherigen Benutzer abgezogen und vom Hotelpersonal dem neuen Gast überreicht werden.In version 2 intended for the hotel sector, the changeover key 90 is turned to the left by approximately 90 °, the new combination is set and the key is turned to the right again. In the changeover position, the key can be withdrawn by the previous user and handed over to the new guest by the hotel staff.

Es ist üblich, auf den Kodierungsknöpfen 26 Einstellpositionen für das Alphabet vorzusehen. Bei drei Knöpfen erhält man 263 = 17 576 Kombinationen. Mit vier Einheiten erreicht man 456976 Kombinationen. Wenn man zum Alphabet mit 26 Zeichen die Ziffern 1-9 hinzufügt, erzielt man mit drei Einheiten 353 = 42 875 Kombinationen.It is customary to provide 26 setting positions for the alphabet on the coding buttons. With three buttons you get 26 3 = 17 576 combinations. With four units you can achieve 456976 combinations. If you add the digits 1-9 to the alphabet with 26 characters, you get 35 3 = 42 875 combinations with three units.

Eine andere Möglichkeit, die Zahl der Kombinationen zu erhöhen, besteht darin, zwei Schlösser in eine Tür einzubauen.Another way to increase the number of combinations is to install two locks in one door.

Bester Weg zur Ausführung der Erfindung Der beste Weg zur Umsetzung der Erfindung in die Praxis ist darin zu sehen, dass man die beschriebene Dreiknopf-Version mit 263 Kombinationen realisiert, wobei zumindest Schlosskasten, Riegelplatte, Sperrscheiben, Sperrschieber und Kodierungsknöpfe aus Druckguss gefertigt werden. Die besonders flachen Teile, wie Umstellschieber und Zuhaltungen, werden aus Blech gestanzt.Best way to carry out the invention The best way to put the invention into practice is to see that the three- button version described is realized with 26 3 combinations, at least the lock case, locking plate, locking washers, locking slide and coding buttons being made of die-cast. The particularly flat parts, such as diverter and tumblers, are punched out of sheet metal.

Gewerbliche VerwertbarkeitCommercial usability

Das neuartige Kombinationsschloss ist preiswert in der Herstellung, ausserordentlich einfach zu bedienen und sicher in der Handhabung. Die Änderung der Kombination kann auch von ungeübten Benutzern, z.B. Hotelgästen, in wenigen Sekunden duchgeführt werden. Somit ist es im Gegensatz zu einachsigen Kombinationsschlössern hervorragend geeignet z.B. in Hotel- oder Bankschliessfächern eingesetzt zu werden.The new combination lock is inexpensive to manufacture, extremely easy to use and safe to use. The combination can also be changed by inexperienced users, e.g. Hotel guests can be carried out in a few seconds. In contrast to uniaxial combination locks, it is excellently suitable e.g. to be used in hotel or bank lockers.

Der entscheidende Vorteil dieses Schlosses besteht darin, dass es wegen der besonderen internen Verriegelungen in jeder Hinsicht abtastsicher ist.The key advantage of this lock is that it is touch-proof in every respect due to the special internal locks.
