Description

Technisches GebietTechnical field

Die Erfindung betrifft ein umstellbares Doppelbartschloß mit einem Riegel, in dem eine Umstellschneide und ein Paket Zahnscheiben gelagert sind. Den Zahnscheiben steht ein Paket Zuhaltungen gegenüber, die um einen Dorn schwenkbar angeordnet sind.The invention relates to a convertible double-bit lock with a bolt in which one Changing edge and a package of tooth lock washers are stored. The tooth lock washer a package of tumblers opposite, which are arranged pivotably about a mandrel.

Stand der TechnikState of the art

Bei den bekannten Schlössern dieser Art erfolgt die Umstellung des Schlosses von hinten. Man schließt das Schloß mit dem bisher benutzten Schlüssel auf, öffnet die Tür und betätigt einen aus der Schloßrückwand herausragenden Umstellhebel, der die Umstellschneide aushebt. Anschließend zieht man den Schlüssel ab und führt einen anders codierten Schlüssel ein. Nach dem Umdrehen des Schlüssels und der Neuordnung der Codierung werden die Zahnscheiben durch die Umstellschneide erneut blockiert. Damit ist die Umstellung abgeschlossen.
Ein Schloß dieser Bauart wird beispielsweise in der EP 0 773 338 beschrieben und dargestellt.
Es wird als nachteilig angesehen, daß man zur Umstellung die Schranktür öffnen muß. Vor allem bei Schränken mit zwei Schlössern ist es lästig und zeitraubend, daß der Berechtigte für das zweite Schloß hinzugezogen werden muß.
Aus dem deutschen Patent 194 159 ist ein umstellbares Sicherheitsschloß bekannt geworden, bei dem die Umkodierung von vorn durch das Schlüsselloch erfolgen kann. Um die Umstellung einzuleiten, muß der Hauptriegel mit dem bisher benutzten Schlüssel um eine Tour vorgeschoben werden. In dieser Stellung werden die Sperrplatten von den vom Schlüssel betätigten Platten getrennt. Wenn jetzt der Schlüssel abgezogen und durch einen anders kodierten ersetzt wird, werden die Zuhaltungen auf den neuen Schlüsselbart eingestellt. Dreht man den Schlüssel weiter, wird das Schloß doppelt geschlossen.Man muß dabei zweimal umschließen. Wenn der Benutzer des Schrankes aus Versehen nur einmal umschließt, kann jeder Dritte den Schrank mit einem anders kodierten Schlüssel öffnen. In the known locks of this type, the lock is rearranged. You unlock the lock with the key you used previously, open the door and operate a change-over lever protruding from the rear wall of the lock that lifts the change-over blade. Then you remove the key and insert a differently coded key. After turning the key and rearranging the coding, the lock washers are blocked again by the change-over blade. The conversion is now complete.
A lock of this type is described and illustrated, for example, in EP 0 773 338.
It is considered disadvantageous that the cabinet door has to be opened for the changeover. Especially in cupboards with two locks, it is annoying and time-consuming that the person entitled must be consulted for the second lock.
From German patent 194 159 a convertible security lock is known in which the recoding can be done from the front through the keyhole. In order to initiate the change, the main bolt with the key previously used must be pushed forward by one tour. In this position, the locking plates are separated from the plates operated by the key. If the key is now removed and replaced by a differently coded one, the tumblers are set to the new key bit. If you keep turning the key, the lock is closed twice, and you have to lock it twice. If the user accidentally encloses the cabinet only once, every third person can open the cabinet with a differently coded key.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ein Doppelbartschloß so umzugestalten, daß es mit einfachen Mitteln von vorne über das Schlüsselloch umstellbar ist, wobei bereits nach einer Schlüsselumdrehung eine manipulationssichere Verriegelung erreicht werden soll.
Diese Aufgabe wird dadurch gelöst, daß am Boden des Gehäuses ein Umstellwirbel gelagert ist, der vom Bart eines Umstellschlüssels betätigt werden kann und dabei eine Umstellsperre verschiebt, daß eine Nase dieser Umstellsperre einen Sperrwinkel freigibt, der unter Federkraft in die Öffnungsposition umklappt, und daß beim Rückzug des Riegels die Umstellschneide gegen einen Arm des Sperrwinkels läuft und das Zahnscheibenpaket freigibt. The invention has for its object to redesign a double-bit lock so that it can be changed from the front through the keyhole with simple means, a tamper-proof locking should be achieved after just one key rotation.
This object is achieved in that a change swivel is mounted on the bottom of the housing, which can be actuated by the beard of a change key and thereby moves a change lock that a nose of this change lock releases a locking angle that folds under spring force into the open position, and that when Withdrawal of the lock, the change-over blade runs against an arm of the locking bracket and releases the toothed lock washer.

    • In Fig. 1a ist mit 1 das Schloßgehäuse bezeichnet, in dem nur die Teile dargestellt sind, die unter dem herausgenommenen Riegel 2 (Fig. 1b) liegen und der Umstellung der Kombination dienen. Das Gehäuse 1 weist an der linken Stirnseite eine rechteckige Öffnung 1a auf, aus der der Riegelkopf 2a heraustritt. Aus dem Boden des Schloßgehäuses ragen vier Hohlsäulen 1b, 1c, 1d, 1e heraus, die der Aufnahme von Befestigungsschrauben dienen. Der Schlüsselführungsdorn trägt das Zeichen 1f. Weitere Führungsdorne 1g, 1h verhindern Kippbewegungen des Riegels 2. Die zugehörigen Schlitze im Riegel sind mit 2b, 2c bezeichnet.
    Ein Lagerdorn 1i nimmt das Zuhaltungspaket 3 auf, das auf der Bodenfläche 2d des Riegels aufliegt.
    Die der Umstellung dienenden Teile sind ein Umstellwirbel 4, eine Umstellsperre 5 und ein Sperrwinkel 6, die in Fig. 5 - 7 vergrößert dargestellt sind.
    Der Umstellwirbel 4 ist auf dem Führungsdorn 1h gelagert. Er weist eine Steuerkurve 4a auf, die von dem Bart 7 eines Umstellschlüssels (Fig. 2a) betätigt wird. Der Umstellwirbel 4 trägt ferner einen Steuerdorn 4b, der in einer Steueraussparung 5a der Umstellsperre 5 gleitet. Diese ist verschiebbar gelagert und trägt eine angeformte Feder 5b. Eine Nase 5c verhindert in der Position nach Fig. 1a, daß der Sperrwinkel 6 nach rechts schwenken kann. Der Sperrwinkel 6 ist auf einem Dorn 1k gelagert. Eine angeformte Feder 6a bewirkt, daß der Winkel 6 nach rechts schwenkt, wenn entsprechend Fig. 2a die Umstellsperre 5 ihre rechte Endstellung einnimmt.     In Fig. 1a, 1 denotes the lock housing, in which only the parts are shown, which are under the removed bolt 2 (Fig. 1b) and serve to change the combination. The housing 1 has a rectangular opening 1a on the left end, from which the locking head 2a emerges. Four hollow columns 1b, 1c, 1d, 1e protrude from the bottom of the lock housing and serve to hold fastening screws. The key guide mandrel bears the symbol 1f. Further guide pins 1g, 1h prevent tilting movements of the bolt 2. The associated slots in the bolt are labeled 2b, 2c.
    A bearing mandrel 1i receives the tumbler package 3, which rests on the bottom surface 2d of the bolt.
    The parts used for the changeover are a changeover swivel 4, a changeover lock 5 and a locking angle 6, which are shown enlarged in FIGS. 5-7.
    The changeover swivel 4 is mounted on the guide mandrel 1h. It has a control curve 4a which is actuated by the beard 7 of a changeover key (FIG. 2a). The changeover swivel 4 also carries a control pin 4b which slides in a control recess 5a of the changeover lock 5. This is slidably mounted and carries a molded spring 5b. In the position according to FIG. 1a, a nose 5c prevents the locking angle 6 from pivoting to the right. The locking angle 6 is mounted on a mandrel 1k. A molded-on spring 6a causes the angle 6 to pivot to the right when, according to FIG. 2a, the change-over lock 5 assumes its right end position.

    In Fig. 1b erkennt man, daß dem Zuhaltungspaket 3 ein Zahnscheibenpaket 8 gegenübersteht, das im Riegel 2 verschiebbar gelagert ist. Eine Umstellschneide 9 greift in die Verzahnung der Scheiben ein und arretiert die gewählte Codierung.
    Wenn man den passenden Schlüssel in das Schloß einführt und im Uhrzeigersinn verdreht, werden die Zuhaltungen richtig eingeordnet, so daß ihre Zungen 3a in die Schlitze der Zahnscheiben 8 eintreten können, wie es Fig. 3b zeigt.
    Im normalen Betrieb des Schlosses werden die Teile 4, 5 und 6 nicht verstellt.
    Der Schlüssel läßt sich nur um etwa 135° drehen, weil sein Bart gegen die Nase 6b des Sperrwinkels 6 stößt. Er kann also bei zurückgezogenem Riegel nicht abgezogen werden.
    Der Umstellvorgang läuft wie folgt ab:
    Man führt bei verschlossener Tür, also ausgefahrenem Riegel, den Umstellschlüssel ein und dreht seinen Bart 7 um 90° nach links, um den Umstellwirbel 4 aus der Sperrposition nach Fig. 1a in die Umstellposition nach Fig. 2a zu bringen. Die Umstellsperre 5 wird dabei über den Steuerdorn 4b nach rechts geschoben, so daß auch der Sperrwinkel 6 in die Umstellposition nach Fig. 2a umklappen kann.
    Der Umstellschlüssel wird jetzt um 90° nach rechts gedreht und abgezogen. Man führt den passenden Doppelbartschlüssel ein und dreht ihn um 180° nach rechts. Der bisher gültige Schlüssel wird jetzt bei zurückgezogenem Riegel 2 abgezogen und durch einen beliebig codierten neuen Schlüssel ersetzt, der in 180°-Position in das Schlüsselloch eingeführt werden muß. Beim Aufschließen des Schlosses, dessen Sperrwinkel nach Fig. 3a in Umstellposition ist, stößt der linke Arm 6c des Sperrwinkels gegen die Umstellschneide 9, die entsprechend Fig. 4 mit Hilfe eines Rahmens 9a federnd an der Unterseite des Riegels 2 gelagert ist. Hierdurch wird die Umstellschneide 9 aus den Zähnen der Scheiben 8 ausgehoben, wie es Fig. 3b klar zeigt.
    Zusätzlich stößt ein Dorn 2e an der Unterseite des Riegels 2 gegen die Fläche 4c des Umstellwirbels 4 und schwenkt diesen in die Sperrlage nach Fig. 3a zurück.
    Wenn jetzt der neue Schlüssel nach links gedreht wird, ordnet er die Zuhaltungen 3 und die damit gekuppelten Zahnscheiben 8 neu ein, während der Riegel 2 ausgefahren wird. Zusätzlich drückt der Schlüsselbart den Sperrwinkel 6 in eine Linksdrehung, so daß der Sperrzustand nach Fig. 1a wieder hergestellt wird. Die Umstellschneide 9 rastet infolge der Federwirkung des Rahmens 9a in die Verzahnung des Zahnscheibenpaketes 8 ein.
    Beim nächsten Aufschließen bleibt der Schlüssel wieder im Schlüsselloch gefangen, weil sein Bart durch die Nase 6b aufgehalten wird.
    Der gesamte Umstellvorgang findet statt, ohne daß die Tür des Schrankes geöffnet werden muß.     In Fig. 1b it can be seen that the tumbler package 3 is opposed by a lock washer package 8 which is slidably mounted in the bolt 2. A change-over cutting edge 9 engages in the toothing of the disks and locks the selected coding.
    If you insert the appropriate key into the lock and turn it clockwise, the tumblers are correctly arranged so that their tongues 3a can enter the slots in the toothed disks 8, as shown in FIG. 3b.
    Parts 4, 5 and 6 are not adjusted during normal operation of the lock.
    The key can only be turned by about 135 ° because his beard hits the nose 6b of the locking angle 6. It cannot be removed when the bolt is withdrawn.
    The changeover process is as follows:
    When the door is closed, that is to say the bolt is extended, the change-over key is inserted and his beard 7 is turned 90 ° to the left in order to bring the change-over swivel 4 from the locked position according to FIG. 1a into the change-over position according to FIG. 2a. The changeover lock 5 is pushed over the control pin 4b to the right, so that the locking angle 6 can also fold over into the changeover position according to FIG. 2a.
    The changeover key is now turned 90 ° to the right and removed. You insert the appropriate double-bit key and turn it 180 ° to the right. The previously valid key is now withdrawn with the bolt 2 withdrawn and replaced with any new key that is coded in any way and which has to be inserted into the keyhole in the 180 ° position. When unlocking the lock, the locking angle of which is in the changeover position according to FIG. 3a, the left arm 6c of the lock angle abuts against the changeover blade 9 which, according to FIG. 4, is resiliently mounted on the underside of the bolt 2 with the aid of a frame 9a. As a result, the changeover blade 9 is lifted out of the teeth of the disks 8, as is clearly shown in FIG. 3b.
    In addition, a mandrel 2e abuts the underside of the latch 2 against the surface 4c of the changeover swivel 4 and swivels it back into the locked position according to FIG. 3a.
    If the new key is now turned to the left, it rearranges the tumblers 3 and the toothed lock washers 8 coupled to them while the bolt 2 is being extended. In addition, the key bit presses the locking angle 6 into a left turn, so that the locking state according to FIG. 1a is restored. Due to the spring action of the frame 9a, the changeover blade 9 engages in the toothing of the toothed disk set 8.
    The next time the key is unlocked, the key remains trapped in the keyhole because its beard is held open by the nose 6b.
    The entire changeover takes place without the door of the cabinet having to be opened.

Change-over double-bit lock with a bolt (2), in which a change-over edge member (9) and an assembly of toothed plates (8) are mounted, wherein an assembly of tumblers (3) is disposed oppposite the toothed plates, these tumblers being pivotably mounted about a pin (1i) and brought into position by a double-bit key, characterised in that a change-over swivel (4) is mounted at the bottom of the housing (1), which swivel can be actuated by the bit (7) of a change-over key and in the process displaces a change-over catch (5), in that a projection of this change-over catch (5) releases a locking angle (6), which turns round under spring force into the open position, and in that the change-over edge member (9) runs up against an arm (6c) of the locking angle (6) and releases the toothed plate assembly (8) when the bolt (2) is pulled back.
    2. Change-over double-bit lock according to Claim 1, characterised in that the bolt (2) bears a pin (2e) at the underside which pulls back the change-over swivel (4), and in that the new key resets the locking angle (6) when turned back for reprogramming.
