摘要:
The lock comprises tumblers that are composed of two parts provided with oppositely arranged sets of teeth which can mesh frontally. By means of a combination-changing key, the sets of teeth are arranged according to a new combination which corresponds to the combination of the new actuation key.

A closure system has card keys (K) to be handed out provided with a code and whose broad side surfaces are subdivided into individual fields (E) that can be magnetically coded in distinct manner for each lock/card holder. These individual fields (E) move into the open position magnetic locking pins (31) which are accordingly positioned and which act as tumblers for the lock (4). In order to enlarge the range of possible applications, a service station (SA) changes the coding of data identification individual fields (E1) of the key (K), so as to increase or reduce their value, and an evaluation station is provided with a reading device for acquiring and storing such changes of code in association with other codes of the card key (K).

The safety lock with one or more retainer plates moreover comprises a variable size recoding element (11) having a succession of sizes (KO, Kl, K2), each which enables a corresponding key (2a, 2b, 2c) of the type with one or more bits and which disables every key (2a, 2b) enabled by every preceding size in the succession, each key having its own control means of the recoding element adapted to automatically restore it in the size which enables the key when the recoding element has a size preceding that which enables the key.
摘要:
A break-in resistant lock (1), of the type which comprises a box-like body (2) for accommodating a plurality of contoured plates (3) provided with a respective portion which is suitable for detachable engagement on a corresponding area of a rod (4) which can perform a translational motion and supports, at its free end (5), at least one bolt (6) which can retract monolithically with the rod (4). The plates (3) can perform a vertical translational motion by way of the action of the key and release, when they are raised, the translational motion of the rod (4) and the bolts (6) for their retraction and protrusion. At least one of the plates (3) comprises at least one area (7) provided with at least one seat (8) which is aligned and proximate to at least one protrusion (9) which is shaped substantially complementarily with respect to the shape of the seat (8). The at least one plate (3) provided with the at least one seat (8) is able to oscillate, about a guiding pivot (10) rigidly coupled to the box-like body (2), from a first configuration for mutual engagement of the at least one seat (8) with the respective at least one protrusion (9), as a consequence of external break-in actions aimed at retracting the rod (4) and the bolts (6), in which translational motion of the plates (3) is not allowed and therefore the rod (4) is locked, to a second inactive configuration, in which the seat (8) and the protrusion (9) are spaced and the translational motion of the plates (3) is free and therefore the rod (4) can be extracted and retracted.

摘要:
Vorgeschlagen wird ein Schloß für Sicherheitstüren mit einer Falle (8) und einem Riegel, welcher über ein Zuhaltungswerk aus Schließzuhaltungen (3) und Sperrzuhaltungen (4) betätigbar ist. Die Schließzuhaltungen (3) weisen jeweils mindestens eine Sperrstruktur (31) auf und sind unmittelbar durch den Schlüsselbart betätigbar in dem Schloßgehäuse (6) gelagert. Die Sperrzuhaltungen (4) sind quer zur Bewegungsrichtung der Schließzuhaltungen (3) beweglich und jeweils mit mindestens einer Sperrstruktur (30) versehen, die in formschlüssigen Eingriff mit der korrespondierenden Sperrstruktur (31) der Schließzuhaltung (3) bringbar ist. Zur Erzielung besonders hoher Sicherheitsanforderungen sind sämtliche Sperrzuhaltungen (4) auf einem quer zur Bewegungsrichtung der Schließzuhaltungen (3) geführten Notriegel (18) angeordnet, wobei die Sperrzuhaltungen (4) parallel zur Bewegungsrichtung der Schließzuhaltungen (3) am Notriegel (18) geführt sind. Übertragungsmittel (16) setzen die Schlüsselbewegung in eine Auslenkung des Notriegels (18) bis zu einer Maximalauslenkung um, in der die Zuhaltungen (3, 4) miteinander in Eingriff stehen. Die Übertragungsmittel (16) sind dergestalt, 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. Vorzugsweise dient als Übertragungsmittel (16) ein Mitnehmer, mit dem die Platte (18) gekoppelt ist.
摘要:
Schloss mit Zuhaltungen (3) in einem im wesentlichen flachen Schlosskasten (1), wobei das Schloss um eine Drehachse (8) verschwenkbare Zuhaltungen (3) aufweist und wobei zum Verschwenken der Zuhaltungen (3) ein Schlüssel (6) vorgesehen ist, und wobei ein Riegel (2) im Schlosskasten (1) verschiebbar angeordnet ist. Erfindungsgemäß ist vorgesehen, dass die Zuhaltungen (3) relativ zur Drehachse (8) in Richtung ihrer Fläche in ihrer Lage verstellbar sind, wobei die Verstellung im wesentlichen senkrecht zur Verschieberichtung des Riegels erfolgt. Weiterhin betrifft die Erfindung ein Verfahren zum Umkodieren eines Schlosses mit Zuhaltungen.
摘要:
A lock with flat tumblers and changeable code comprises tumblers which are composed of two parts (15,14) which have mutually opposite sets of teeth (30,31) which are adapted to mutually mesh according to a preset code. The code is changed by mutually spacing the sets of teeth with a suitable tool (85) and by restoring their meshing according to the code of a new key.
