Definitions

  • the invention relates to a lock with a locking function to be released by inserting a regionally magnetized key card, in which the key card entrains a slide released by the magnetic tumbler pins.

  • the known locks of the aforementioned type are constructed in such a way that they have a slide having magnetic tumbler pins. Bearing recesses are provided in the slide for accommodating the tumbler pins, the tumbler pins interacting with a correspondingly polarized key card. By inserting the correct key card, the magnetic tumbler pins leave a locking plate so that the slide card can be moved by means of the key card.
  • the object of the invention is based on the object of increasing the use value of the lock in a lock of the type in question in a technically simple manner by means of a supplementary use function.
  • a lock of the type in question is created, which is complemented by a Usage function has an increased use value, characterized in that a part of the magnetic areas of the key in the release position of the slide causes a memory arranged in the lock to store data, preferably the date and time of the key insertion time, on the other hand, the user of the lock does not know whether this Saving is now (currently) in function or not.
  • the memory can then be provided for a plurality of key insertion times, for example twenty.
  • the key card to be inserted into the lock thus not only has a magnetized area containing the opening code combination matched to the lock, but also has a further magnetized partial area for initiating the date / time memory arranged in the lock.
  • the initiating part of the key is optically indistinguishable from the locking area, and it also does not influence the locking function of the lock, so that said part can be magnetized differently in the case of several key cards having the same opening code combination. It is also impossible to locate it without knowing the inside of the castle.
  • a sub-area of the magnetized key points can embody a personal user code, which then also stores in the memory who of a number of authorized persons has closed at a specific time. When the memory is called up, it is also output as a number, for example.
  • the memory can be designed in the form of a chip arranged in the lock housing, which contains the date / time and in each case stores a specific number of individual data associated with it in such a way that when a maximum number of individual data is exceeded, the first data are deleted again and replaced by new ones. With a maximum storage of, for example, twenty individual data, the date, time and possibly user code of the last twenty key insertion times are thus stored, provided the key cards are provided with a magnetized partial area which causes the memory.
  • the individual data stored in the chip can be called up. This can be realized, for example, by the chip of the lock being connected or being connectable to a computer unit which evaluates the individual data.

This can also be done after the storage has been removed and then possibly only at another point, for example as a service from the locking system supplier. This has advantages in terms of technology. B. in that after a theft in a hotel room the memory can be removed and checked / accessed unchanged under objective supervision.

  • the invention can advantageously also be applied to recodable locks.
  • a follow-up key is magnetized in the area of its opening code combination in such a way that after the same has been inserted, the combination of the lock is adjusted so that the previously valid guest key card no longer has the now valid opening code combination.

Abstract

The invention concerns a lock (1) opened by the insertion of a partially magnetized code card (8) and proposes, in order to produce a particularly user-friendly design, that a store (S) be fitted which is initiated in the lock-release position and which can be deactivated without neutralizing the lock-closure function and which, in use, stores, in such a way that the store can be interrogated, card code data in relation to other, absolute, data such as date and time of insertion of the card for a multiplicity of card insertions.

Description

Die Erfindung betrifft ein Schloß mit durch Einschieben einer bereichsweise magnetisierten Schlüsselkarte freizugebender Schließfunktion, bei welchem die Schlüsselkarte einen von den magnetischen Zuhaltungsstiften freigegebenen Schieber mitschleppt.The invention relates to a lock with a locking function to be released by inserting a regionally magnetized key card, in which the key card entrains a slide released by the magnetic tumbler pins.

Ein solches Schloß ist aus WO-A-8 912 155 bekannt.Such a lock is known from WO-A-8 912 155.

Die bekannten Schlösser der vorgenannten Art sind in der Weise aufgebaut, daß sie einen, magnetische Zuhaltungsstifte aufweisenden Schieber besitzen. Zur Unterbringung der Zuhaltungsstifte sind in dem Schieber Lagerausnehmungen vorgesehen, wobei die Zuhaltungsstifte mit einer entsprechend polarisierten Schlüsselkarte zusammenwirken. Durch Einschub der vorschriftsmäßigen Schlüsselkarte verlassen die magnetischen Zuhaltungsstifte eine Sperrplatte, so daß mittels der Schlüsselkarte eine Schieberverlagerung vorgenommen werden kann.The known locks of the aforementioned type are constructed in such a way that they have a slide having magnetic tumbler pins. Bearing recesses are provided in the slide for accommodating the tumbler pins, the tumbler pins interacting with a correspondingly polarized key card. By inserting the correct key card, the magnetic tumbler pins leave a locking plate so that the slide card can be moved by means of the key card.

Dem Gegenstand der Erfindung liegt die Aufgabe zugrunde, bei einem Schloß der in Rede stehenden Art in herstellungstechnisch einfacher Weise den Gebrauchswert des Schlosses durch eine ergänzende Benutzungsfunktion zu erhöhen.The object of the invention is based on the object of increasing the use value of the lock in a lock of the type in question in a technically simple manner by means of a supplementary use function.

Gelöst wird die Erfindungsaufgabe durch die im Patentanspruch 1 angegebene Erfindung.The object of the invention is solved by the invention specified in claim 1.

Die Unteransprüche stellen vorteilhafte Weiterbildungen der erfinderischen Lösung dar.The subclaims represent advantageous developments of the inventive solution.

Zufolge derartiger Ausgestaltung ist ein Schloß der in Rede stehenden Art geschaffen, welches durch eine ergänzende Benutzungsfunktion einen erhöhten Gebrauchswert aufweist, dadurch, daß ein Teil der magnetischen Bereiche des Schlüssels in Freigabestellung des Schiebers einen im Schloß angeordneten Speicher veranlaßt, Daten, vorzugsweise jeweils Datum und Uhrzeit des Schlüsseleinschubzeitpunktes, abrufbar abzuspeichern, andererseits der Benutzer des Schlosses nicht weiß, ob diese Abspeicherung nun (momentan) in Funktion ist oder nicht. Der Speicher kann dann für eine Mehrzahl von Schlüsseleinschubzeitpunkten, z.B. zwanzig, vorgesehen sein. Die in das Schloß einzuführende Schlüsselkarte weist somit nicht nur einen die auf das Schloß abgestimmte Öffnungscode-Kombination beinhaltenden magnetisierten Bereich auf, sondern besitzt zudem einen weiteren magnetisierten Teilbereich zur Initiierung des im Schloß angeordneten Datums/Uhrzeit-Speichers. Als besonders vorteilhaft erweist es sich hierbei, daß diese zusätzliche Kontrollfunktion der Schlüsselkarte nicht erkennbar ist. Der initiierende Teilbereich des Schlüssels ist optisch nicht vom Schließungs-Bereich zu unterscheiden, und er beeinflußt auch nicht die Schließfunktion des Schlosses, so daß der genannte Teilbereich bei mehreren, dieselbe Öffnungscode-Kombination aufweisenden Schlüsselkarten unterschiedlich magnetisiert sein kann. Er ist auch nicht zu lokalisieren ohne Kenntnis vom Inneren des Schlosses. Es kann zusätzlich ein Teilbereich der magnetisierten Schlüsselpunkte einen Personenbenutzercode verkörpern, der dann auch im Speicher niederlegt, wer von einer Anzahl schließberechtigter Personen zu einer bestimmten Uhrzeit geschlossen hat. Bei Abruf des Speichers wird auch dieser dann z.B. als Ziffer ausgegeben. Dies ist beispielsweise vorteilhaft bei HotelzimmerSchlössern, wobei die Schlüsselkarten des Hotelpersonals ergänzend einen anderen magnetisierten Teilbereich als Benutzercode aufweisen, als der Generalschlüssel. Auch besteht die Möglichkeit, die Schlüsselkarten der Hotelgäste ohne einen derartigen magnetisierten Teilbereich zu versehen. Der Speicher kann in Form eines im Schloßgehäuse angeordneten Chips ausgebildet sein, der Datum/Uhrzeit enthält und jeweils dazu eine bestimmte Anzahl von Einzeldaten zugeordnet speichert derart, daß bei Überschreiten einer maximalen Anzahl von Einzeldaten die ersten Daten wieder gelöscht und durch neue ersetzt werden. Bei einer maximalen Speicherung von beispielsweise zwanzig Einzeldaten sind somit Datum, Uhrzeit und evtl. Benutzercode der letzten zwanzig Schlüsseleinschubzeitpunkte gespeichert, sofern die Schlüsselkarten mit einem den Speicher veranlassenden, magnetisierten Teilbereich versehen sind. Die in dem Chip gespeicherten Einzeldaten sind abrufbar. Dies kann beispielsweise dadurch realisiert sein, daß der Chip des Schlosses mit einer Rechnereinheit in Verbindung steht oder bringbar ist, welche die Einzeldaten auswertet. Alternativ hierzu ist es auch möglich, die Daten direkt am Schloß über eine Schnittstelle abzurufen. Auch kann dies nach Entnahme des Speichers und dann eventuell nur dann und damit an anderer Stelle geschehen, z.B. als Service des Schließanlagen-Lieferanten. Das hat krminaltechnische Vorteile z. B. dahingehend, daß nach einem Diebstahl in einem Hotelzimmer der Speicher entnommen und unverändert unter objektiver Aufsicht überprüft/abgerufen werden kann. Das Abfragen des Speichers kann grundsätzlich nur einem beschränkten Personenkreis möglich sein. Jeder Einschub eines falschen Schlüssels wird nicht im Speicher festgehalten, weil ein falscher Schlüssel den Schieber nicht in Freigabestellung bringen kann. Das Kommando an den Speicher zum Abspeichern kann mittels im Schloßgehäuse angeordneter Sensoren, z.B. Hall-Sonden und/oder Induktionsspulen erfolgen. Durch Einschieben einer mit einem magnetisierten Teilbereich versehenen Schlüsselkarte werden dann in den Induktionsspulen Induktionsspannungen erzeugt, welche von dem Chip ausgewertet werden. Dann kann eventuell wegen dieser Eigenversorgung die Batterie für den Speicher/Leser entfallen. Vorteilhafterweise kann die Erfindung auch bei umcodierbaren Schlössern angewendet werden. Hierbei ist ein Nachfolgeschlüssel im Bereich seiner Öffnungscode-Kombination derart magnetisiert, daß nach Einschieben desselben die Kombination des Schlosses verstellt wird, so daß die zuvor gültige Gäste-Schlüsselkarte nicht mehr die nun gültige Öffnungscode-Kombination aufweist. Eine derartige Ausgestaltung ist beispielsweise aus der DE-OS 37 28 072 bekannt. Hier könnten auch die Schlüsselkarten der Gäste mit einem den Speicher initiierenden, magnetisierten Teilbereich versehen sein, womit zusätzlich zu den genannten Daten auch die Schlüsselkartennummer abgespeichert werden kann. Es ist somit ein Schloß mit einem erhöhten Sicherheitswert geschaffen. Alternativ kann die Anordnung auch so getroffen sein, daß ein den Schieber und/oder die Schlüselkarte abfragender Schalter vorgesehen ist, der bei vorverlagerter Stellung des Schiebers den Speicher entsprechend in Wirkung setzt. Der Speicher kann von einer im Schloß angeordneten Batterie gespeist sein oder mit dieser eine Baueinheit verkörpern. In Verbindung mit der Abfrage der Daten über eine Schnittstelle direkt im Schloßgehäuse weist die Anordnung der Batterie im Schloß insbesondere den Vorteil auf, daß das Schloß in einfachster Weise an einer Tür befestigt werden kann, ohne daß Verkabelungen zur Versorgung des Speichers und zur Abfrage der Daten vorgenommen werden müssen. Es ist somit auch möglich, handelsübliche Kartenschlösser gegen Kartenschlösser auszutauschen, die eine erfindungsgemäße Kontrollfunktion aufweisen oder letztere in gattungsgemäße Schlösser einzubringen. Die Schlösser können auch mit einem Freiraum für die entsprechende Kontrolleinheit geliefert sein, um die zugehörige Hardware (Speicher, Leser, Batterie etc.) nachher einzubauen. Der Freiraum kann z. B. auch von einem Zusatzteil gebildet sein, z. B. einem solchen, welches als Winkel gestaltet ist. Der eine Winkelschenkel erstreckt sich parallel zur Anschraubfläche und dient eventuell zur Befestigung. Der andere Winkelschenkel ragt über die Oberseite des Schlosses bis zum Schlüsselkarten-Einsteckschlitz, so daß die Schlüsselkarte sich beim Einschieben vor dem Stirnende des Winkelschenkels vorbeibewegt, um dabei gelesen zu werden, wozu im oberen Schenkel die entsprechende Hardware (Speicher, Batterie, Leseeinrichtung u.s.w.) untergebracht sind bzw. sein können.As a result of such a design, a lock of the type in question is created, which is complemented by a Usage function has an increased use value, characterized in that a part of the magnetic areas of the key in the release position of the slide causes a memory arranged in the lock to store data, preferably the date and time of the key insertion time, on the other hand, the user of the lock does not know whether this Saving is now (currently) in function or not. The memory can then be provided for a plurality of key insertion times, for example twenty. The key card to be inserted into the lock thus not only has a magnetized area containing the opening code combination matched to the lock, but also has a further magnetized partial area for initiating the date / time memory arranged in the lock. It proves to be particularly advantageous here that this additional control function of the key card cannot be recognized. The initiating part of the key is optically indistinguishable from the locking area, and it also does not influence the locking function of the lock, so that said part can be magnetized differently in the case of several key cards having the same opening code combination. It is also impossible to locate it without knowing the inside of the castle. In addition, a sub-area of the magnetized key points can embody a personal user code, which then also stores in the memory who of a number of authorized persons has closed at a specific time. When the memory is called up, it is also output as a number, for example. This is advantageous, for example, in hotel room locks, the key cards of the hotel staff additionally having a different magnetized partial area as the user code than the general key. Also it is possible to provide the key cards of the hotel guests without such a magnetized partial area. The memory can be designed in the form of a chip arranged in the lock housing, which contains the date / time and in each case stores a specific number of individual data associated with it in such a way that when a maximum number of individual data is exceeded, the first data are deleted again and replaced by new ones. With a maximum storage of, for example, twenty individual data, the date, time and possibly user code of the last twenty key insertion times are thus stored, provided the key cards are provided with a magnetized partial area which causes the memory. The individual data stored in the chip can be called up. This can be realized, for example, by the chip of the lock being connected or being connectable to a computer unit which evaluates the individual data. Alternatively, it is also possible to call up the data directly at the lock via an interface. This can also be done after the storage has been removed and then possibly only at another point, for example as a service from the locking system supplier. This has advantages in terms of technology. B. in that after a theft in a hotel room the memory can be removed and checked / accessed unchanged under objective supervision. In principle, only a limited group of people can query the memory. Every insertion of an incorrect key is not stored in the memory because an incorrect key cannot bring the slide into the release position. The memory can be commanded by means of sensors arranged in the lock housing, for example Hall probes and / or induction coils. By inserting a key card with a magnetized section then induction voltages are generated in the induction coils, which are evaluated by the chip. Then the battery for the memory / reader can possibly be omitted because of this self-supply. The invention can advantageously also be applied to recodable locks. Here, a follow-up key is magnetized in the area of its opening code combination in such a way that after the same has been inserted, the combination of the lock is adjusted so that the previously valid guest key card no longer has the now valid opening code combination. Such an embodiment is known for example from DE-OS 37 28 072. Here, the key cards of the guests could also be provided with a magnetized partial area that initiates the memory, with which the key card number can also be stored in addition to the data mentioned. A lock with an increased security value is thus created. Alternatively, the arrangement can also be such that a switch which interrogates the slide and / or the key card is provided, which, when the slide is in the forward position, activates the memory accordingly. The memory can be powered by a battery arranged in the lock or embody a structural unit with it. In connection with the query of the data via an interface directly in the lock housing, the arrangement of the battery in the lock has the particular advantage that the lock can be attached to a door in the simplest way, without the need for cabling to supply the memory and to query the data must be made. It is thus also possible to exchange commercially available card locks for card locks that have a control function according to the invention or to incorporate the latter into generic locks. The locks can also be supplied with a free space for the corresponding control unit so that the associated hardware (memory, reader, battery, etc.) can be installed afterwards. The free space can e.g. B. also be formed by an additional part, for. B. one that is designed as an angle. One angle leg extends parallel to the screw surface and may be used for attachment. The other angle leg protrudes over the top of the lock to the key card slot, so that the key card moves in front of the front end of the angle leg to be read, for which purpose the appropriate hardware (memory, battery, reading device, etc.) are housed or can be.

Gemäß Fig. 1 ist ein erfindungsgemäß gestaltetes Schloß 1 an einer Tür 2 - beispielsweise einer Hotelzimmertür - festgelegt. Das Schloß 1 besitzt einen türaußenseitig angeordneten Schloßkasten 3 rechteckigen Grundrisses, welcher an seinem einen Ende eine Betätigungshandhabe 4 lagert. Mit deren Hilfe kann eine Falle 5 zurückgezogen werden. Eine auf der Innenseite der Tür 2 angeordnete Innendrehhandhabe 6 dagegen ist direkt mit der Falle 5 verbunden, so daß von dieser Seite der Tür 2 aus stets eine Türöffnung erfolgen kann.1, a lock 1 designed according to the invention is attached to a door 2 - for example a hotel room door. The lock 1 has a lock case 3 which is arranged on the outside of the door and has a rectangular plan, which has an actuating handle 4 at one end. With their help, a trap 5 can be withdrawn. An inside turning handle 6 arranged on the inside of the door 2, on the other hand, is directly connected to the latch 5, so that a door opening can always take place from this side of the door 2.

Der Schloßkasten 3 ist an dem der Betätigungshandhabe 4 gegenüberliegenden Ende mit einem Einsteckschlitz 7 für eine bereichsweise magnetisierte Schlüsselkarte 8 versehen, wobei ein magnetisierter Bereich C die Öffnungs-code-Kombination beinhaltet und ein zweiter Teilbereich I zur Initiierung eines im Schloß 1 angeordneten Speichers S dient. Ferner nimmt der Schloßkasten 3 ein Schloßeingerichte 9 auf. Letzteres besitzt ein Bodenteil 10, ein Mittelteil 11 und ein Deckelteil 12. Das halbschalenartige Bodenteil 10 ist mittels in das Mittelteil 11 eintretender Schrauben 13 mit diesem verbunden. Diese beiden vorgenannten Teile 10 und 11 werden zuvor zusammengesteckt, wobei vom Mittelteil 11 in Richtung des Bodenteils 10 gerichtete Zentrierfüße 14 ausgehen, die in dafür vorgesehene Nischen 15 des Bodenteils 10 eingreifen. Die Schrauben 13 dienen gleichzeitig zur Festlegung des Deckelteils 12. Von diesem gehen in Karteneinsteckrichtung verlaufende Gehäuseseitenwände 17 aus, die am karteneinsteckseitigen Ende mit einwärtsgerichteten Stützlappen 18 versehen sind, in welche die Schrauben 13 eingreifen. Das dem Einsteckschlitz 7 gegenüberliegende Ende des Deckelteils 12 besitzt eine Zunge 19, die beim Aufschieben des Deckelteils 12 auf das Mittelteil 11 in eine Ausnehmung 20 eines Doms 21 des Mittelteils 11 eingreift. Ferner ist ein Hintergriff erzielt an dem der Zunge 19 gegenüberliegenden Ende der Seitenwände 17, wozu sich hakenförmige Vorsprünge 22 bzw. 23 vom Mittelteil 11 und Deckelteil 12 übergreifen.The lock case 3 is provided at the end opposite the actuating handle 4 with an insertion slot 7 for a key card 8 magnetized in some areas, a magnetized area C containing the opening code combination and a second partial area I for initiating a memory S arranged in the lock 1 . Furthermore, the lock case 3 receives a lock mechanism 9. The latter has a bottom part 10, a middle part 11 and a cover part 12. The half-shell-like bottom part 10 is connected to the middle part 11 by means of screws 13. These two aforementioned parts 10 and 11 are previously plugged together, starting from the central part 11 in the direction of the bottom part 10 centering feet 14 which engage in niches 15 provided for this purpose in the bottom part 10. The screws 13 serve at the same time to fix the cover part 12. From this, housing side walls 17 extend in the card insertion direction and are provided at the end of the card insertion end with inward-directed support tabs 18 into which the screws 13 engage. The end of the cover part 12 opposite the insertion slot 7 has a tongue 19 which engages in a recess 20 of a dome 21 of the middle part 11 when the cover part 12 is pushed onto the middle part 11. Furthermore, a rear grip is achieved at the end of the side walls 17 opposite the tongue 19, for which purpose hook-shaped projections 22 and 23 overlap from the middle part 11 and cover part 12.

Das Bodenteil 10 sowie das Mittelteil 11 sind an dem dem Einsteckschlitz 7 abgewandten Ende sodann noch mittels zwei weiterer Schrauben 24 zu einer Einheit zusammengefügt. Während für das Bodenteil 10 und Mittelteil 11 Aluminium verwendet ist, besteht das Deckelteil 12 aus Kunststoff. Zwischen dem Deckelteil 12 und dem Mittelteil 11 ist ein ebenfalls aus Kunststoff gefertigter, plattenförmig gestalteter Schieber 25 geführt. Mit seiner einen Breitseite liegt der Schieber 25 auf dem Mittelteil 11 auf. Die gegenüberliegende Führungsfläche bildet eine aus Messing gefertigte Sperrplatte 26, die in das Deckelteil 12 eingelegt und dort mit seitlich vorstehenden Abschnitten unverrückbar festgelegt ist. Die Löcher 29 der Sperrplatte 26 fluchten in der in Fig. 10 dargestellten Verriegelungslage des Schlosses 1 mit als durchgehende Bohrung ausgebildete Lagerausnehmungen 30 des Schiebers 25. In den Lagerausnehmungen 30 liegen magnetische Zuhaltungsstifte 31 ein. Es ist nicht notwendig, in jeder Lagerausnehmung 30 einen Zuhaltungsstift 31 vorzusehen, da sich die Anzahl, die Lage und die Polarität der Zuhaltungsstifte 31 nach der jeweiligen Öffnungscode-Kombination des Schlosses 1 richtet. Insbesondere der dem Initiierungs-Bereich I der Schlüsselkarte 8 zugeordnete Bereich des Schiebers 25 ist nicht mit Zuhaltungsstiften 31 versehen.The bottom part 10 and the middle part 11 are then joined together at the end facing away from the insertion slot 7 by means of two further screws 24 to form a unit. While aluminum is used for the bottom part 10 and middle part 11, the cover part 12 consists of plastic. Between the cover part 12 and the middle part 11 is also made of plastic, plate-shaped slide 25 is guided. With its one broad side, the slide 25 rests on the middle part 11. The opposite guide surface forms a locking plate 26 made of brass, which is inserted into the cover part 12 and is immovably fixed there with laterally projecting sections. The holes 29 of the locking plate 26 are aligned in the in FIG. 10 shown locking position of the lock 1 with a through hole formed bearing recesses 30 of the slider 25. Magnetic tumbler pins 31 are in the bearing recesses 30. It is not necessary to provide a tumbler pin 31 in each bearing recess 30, since the number, the position and the polarity of the tumbler pins 31 depend on the respective opening code combination of the lock 1. In particular, the area of the slide 25 assigned to the initiation area I of the key card 8 is not provided with tumbler pins 31.

Auf der anderen Seite der Sperrplatte 26 befindet sich ein ebenfalls aus Messing bestehendes Leitblech 32, dem eine Ankerplatte 33 gegenüberliegt. Letztere wird von drei Druckfedern 34 in ihrer Position gehalten. Die vorgenannten Druckfedern 34 stützen sich ihrerseits an dem Deckelteil 12 ab.On the other side of the locking plate 26 there is a baffle 32, also made of brass, with an anchor plate 33 opposite it. The latter is held in position by three compression springs 34. The aforementioned compression springs 34 are in turn supported on the cover part 12.

Die Ankerplatte 33 besteht im Gegensatz zu den anderen Bauelementen aus ferromagnetischem Material. Mithin zieht die Ankerplatte 33 die magnetischen Zuhaltungsstifte 31 an, die demzufolge in die Löcher 29 der Sperrplatte 26 eingreifen. In dieser Lage kann der Schieber 25 nicht aus seiner in Fig. 10 veranschaulichten Grundstellung verschoben werden, da der Eingriff der Zuhaltungsstifte 31 in die gehäusefeste Sperrplatte 26 dies verhindert. Es wäre möglich, einen Teil der Lagerausnehmungen 30 des Schiebers 25 in nicht veranschaulichten Drehkörpern des Schiebers vorzusehen, um eine Codeveränderung durch Verdrehen dieser Drehkörper vornehmen zu können.In contrast to the other components, the anchor plate 33 consists of ferromagnetic material. The armature plate 33 thus attracts the magnetic tumbler pins 31, which consequently engage in the holes 29 in the locking plate 26. In this position, the slide 25 cannot be moved out of its basic position illustrated in FIG. 10, since the engagement of the tumbler pins 31 in the locking plate 26 fixed to the housing prevents this. It would be possible to provide part of the bearing recesses 30 of the slide 25 in rotating bodies of the slide, not shown, in order to be able to change the code by rotating these rotating bodies.

Sowohl die Ankerplatte 33 als auch das Leitblech 32 schließen sich an den Einsteckschlitz 7 des Schloßkastens 3 an. Ihre vorderen Querkanten 32',33' sind in entgegengesetzte Richtungen abgewinkelt und bilden einen Zwickel für die einzuschiebende Schlüsselkarte 8. Dabei stellen die einander gegenüberliegenden Breitflächen von Leitblech 32 und Ankerplatte 33 den Schlüsselkarten-Einschubschacht 35 dar.Both the anchor plate 33 and the guide plate 32 connect to the insertion slot 7 of the lock case 3. Their front transverse edges 32 ', 33' are in angled in opposite directions and form a gusset for the key card 8 to be inserted. The opposite broad areas of the guide plate 32 and anchor plate 33 represent the key card insertion slot 35.

Eine als Rückholfeder dienende Zugfeder 36 ist mit ihrem einen Ende an einem Querzapfen 37 des Mittelteils 11 festgelegt. Dieser Querzapfen 37 geht von der dem Schieber 25 gegenüberliegenden Seite des Mittelteils 11 aus und ragt in den Innenraum des Bodenteils 10. Das andere Ende der Zugfeder 36 greift an einem einen Schlitz 38 des Mittelteils 11 durchsetzenden Vorsprung 39 des Schiebers 25 an, wodurch dieser in eine anschlagbegrenzte Grundstellung bewegt wird. Dem Vorsprung 39 sind ferner zwei abgeschrägte Nasen 40, 41 des Schiebers 25 vorgelagert, die ebenfalls wie der Vorsprung 39 das Mittelteil 11 durchgreifen. Die Abschrägungen 40',41' der Nasen 40,41 sind gleichlaufend gestaltet. Sie greifen an schräg abgewinkelten Lappen 42,43 eines Steges 44 einer aus Federmaterial bestehenden Zunge 45 an. Eine mittlere Aussparung 46 derselben wird dabei von der Nase 40 durchsetzt.A tension spring 36 serving as a return spring is fixed at one end to a cross pin 37 of the middle part 11. This cross pin 37 extends from the side of the middle part 11 opposite the slider 25 and projects into the interior of the bottom part 10. The other end of the tension spring 36 engages on a projection 39 of the slider 25 passing through a slot 38 of the middle part 11, whereby this in a stroke-limited home position is moved. The projection 39 is also preceded by two bevelled lugs 40, 41 of the slider 25, which, like the projection 39, also pass through the middle part 11. The bevels 40 ', 41' of the lugs 40, 41 are designed to run in the same direction. They engage on obliquely angled tabs 42, 43 of a web 44 of a tongue 45 made of spring material. A central recess 46 of the same is penetrated by the nose 40.

Das einschubseitige Ende der Federzunge 45 erstreckt sich zwischen dem Mittelteil 11 und dem Bodenteil 10 und ist dort mittels der Schrauben 13 fixiert, die Durchtrittsöffnungen der Federzunge 45 durchgreifen.The insertion-side end of the spring tongue 45 extends between the middle part 11 and the bottom part 10 and is fixed there by means of the screws 13 which pass through the through openings of the spring tongue 45.

Das dem Befestigungsende der Federzunge 45 gegenüberliegende Ende 48 ist gabelförmig gestaltet und greift in eine Ringnut 49 einer innenverzahnten Kupplungshülse 50 ein. Gemäß der entkuppelten Stellung in Fig. 10 umfaßt die Kupplungshülse 50 ein Zahnritzel 51, welches mit einem querschnittsgrößeren Bund 52 in einer Lageröffnung 53 des Bodenteils 10 angeordnet ist. In dem Bund 52 befindet sich ein diametraler Schlitz 54, in welchen ein hammerkopfartiq gestaltetes Ende 55 eines Drückerdorns 56 eintaucht. Derselbe ist drehfest mit der Innendrehhandhabe 6 verbunden.The end 48 opposite the fastening end of the spring tongue 45 is fork-shaped and engages in an annular groove 49 of an internally toothed coupling sleeve 50. According to the decoupled position in FIG. 10, the coupling sleeve 50 comprises a pinion 51, which has a collar 52 with a larger cross section in a bearing opening 53 of the bottom part 10 is arranged. In the collar 52 there is a diametrical slot 54 in which a hammer head-like end 55 of a presser mandrel 56 is immersed. The same is non-rotatably connected to the inner turning handle 6.

Dem Zahnritzel 51 liegt ein Zahnrad 57 gegenüber. Sowohl das Zahnritzel 51 als auch das Zahnrad 57 sind in ihrer Zahnung gleich ausgestaltet und der Innenzahnung der Kupplungshülse 50 angepaßt. Das Zahnrad 57 seinerseits ist fest mit der Außendrehhandhabe 4 verbunden. Zur Lagenstabilisierung der Zahnräder 51,57 dient ein vom Zahnritzel 51 ausgehender Zentrierzapfen 51', welcher in eine querschnittsangepaßte Sackbohrung 57' des Zahnrades 57 eintaucht. Dasselbe erstreckt sich innerhalb des Domes 21 des Mittelteils 11 und liegt dort mit einem querschnittsgrößeren Bund 57'' in einer Lagerhöhlung 58 des Domes 21 ein. In der entkuppelten Stellung umfaßt die Kupplungshülse 50 ausschließlich das Zahnritzel 51 und steht demgemäß nicht in Eingriff mit dem Zahnrad 57. Eine Drehverlagerung der Außendrehhandhabe 4 führt daher zu keiner Mitnahme des Zahnritzels 51 und damit des Drückerdorns 56. Damit die Kupplungshülse 50 ihre Grundstellung nicht ungewollt verläßt, ist eine die Kupplungshülse 50 umfassende Druckfeder D vorgesehen, die sich einerends an der Innenseite des Doms 21 abstützt und andererends einen Bund 50' der Kupplungshülse 50 beaufschlagt.A gear 57 is located opposite the pinion 51. Both the toothed pinion 51 and the toothed wheel 57 have the same toothing and are adapted to the inner toothing of the coupling sleeve 50. The gear 57 in turn is firmly connected to the external turning handle 4. To stabilize the position of the gearwheels 51, 57, a centering pin 51 'is used, which extends from the pinion 51 and which plunges into a cross-sectionally adapted blind bore 57' of the gearwheel 57. The same extends within the dome 21 of the middle part 11 and lies there with a larger cross section 57 ″ in a bearing cavity 58 of the dome 21. In the uncoupled position, the coupling sleeve 50 only includes the pinion 51 and is accordingly not in engagement with the gear 57. A rotational displacement of the external turning handle 4 therefore does not result in entrainment of the pinion 51 and thus the trigger mandrel 56. So that the coupling sleeve 50 does not undesirably assume its basic position a compression spring D comprising the coupling sleeve 50 is provided, which is supported at one end on the inside of the dome 21 and at the other end acts on a collar 50 'of the coupling sleeve 50.

An seinen in Verschieberichtung liegenden Schmalkanten ist der Schieber 25 mit je einem Anschlagnocken 59 bestückt. Diese wirken zusammen mit seitlichen Federabschnitten 60 der Zunge 45, welche Federabschnitte 60 mit Rastnasen 60' mit den Anschlagnocken 59 zusammenwirken.At its narrow edges lying in the direction of displacement, the slide 25 is equipped with one stop cam 59 each. These cooperate with lateral spring sections 60 of the tongue 45, which spring sections 60 with locking lugs 60 'cooperate with the stop cams 59.

Zwischen der Schlüsselkarte 8 und dem Schieber 25 ist eine Formschluß-Kupplung herstellbar. Gebildet ist die Formschluß-Kupplung von einem in einer Bohrung 61 des Schiebers 25 gelagerten Stift 62. Die Bohrung 61 befindet sich am mündungsseitigen Ende des Schlüsselkarten-Einschubschachtes 35. Die beiden Enden 63, 64 des Stiftes 62 sind kegelförmig gestaltet. Die Gesamtlänge des Stiftes 62 ist größer als die Dicke des Schiebers 25. Das dem Mittelteil 11 zugekehrte kegelförmige Ende 64 greift in der Rückverlagerungs-Endstellung des Schiebers 25 in eine kegelstumpfförmige Ausnehmung 65 des Schloßgehäuses bzw. des Mittelteils 11 ein. Die Tiefe dieser Ausnehmung 65 ist geringer als die Höhe des kegelförmigen Endes 64. In dieser Rückverlagerungs-Endstellung steht das andere kegelförmige Ende 63 über die andere Breitfläche des Schiebers 25 vor und ragt in den Schlüsselkarten-Einschubschacht 35 hinein derart, daß sich das kegelförmige Ende 63 unter Durchsetzen eines Längsschlitzes 66 des Leitbleches 32 an der Ankerplatte 33 abstützt. Der Stift 62 wirkt zusammen mit einer Ausnehmung 67 der Schlüsselkarte 8.A form-locking coupling can be produced between the key card 8 and the slider 25. The positive-locking coupling is formed by a pin 62 mounted in a bore 61 of the slide 25. The bore 61 is located at the mouth end of the key card insertion slot 35. The two ends 63, 64 of the pin 62 are conical. The total length of the pin 62 is greater than the thickness of the slider 25. The conical end 64 facing the middle part 11 engages in the end displacement position of the slider 25 in a frustoconical recess 65 of the lock housing or of the middle part 11. The depth of this recess 65 is less than the height of the conical end 64. In this rearward displacement end position, the other conical end 63 projects beyond the other broad surface of the slide 25 and projects into the key card insertion slot 35 in such a way that the conical end 63 is supported on the anchor plate 33 by passing through a longitudinal slot 66 of the guide plate 32. The pin 62 acts together with a recess 67 in the key card 8.

In dem der Zunge 19 zugewandten Bereich ist in dem Dekkelteil 12 mittig ein als Speicher S dienender Chip 68 angeordnet. Letzterer wird über eine im Schloßkasten 3 angeordnete, jedoch nicht dargestellte Batterie gespeist. In dem gezeigten Ausführungsbeispiel sind dem Chip 68, in Verlagerungsrichtung des Schiebers 25 gesehen, zwei Induktionsspulen 69,70 vorgelagert, welche in Verbindung mit dem Chip 68 stehen. Die Anordnung ist hierbei so getroffen, daß die Induktionsspulen 69,70 außerhalb des Bereiches der ferromagnetischen Ankerplatte 33 liegen.In the area facing the tongue 19, a chip 68 serving as a memory S is arranged in the center of the cover part 12. The latter is powered by a battery arranged in the lock case 3 but not shown. In the exemplary embodiment shown, two induction coils 69, 70 are located in front of the chip 68, as seen in the direction of displacement of the slide 25, which are connected to the chip 68. The arrangement is such that the induction coils 69, 70 lie outside the area of the ferromagnetic armature plate 33.

Es stellt sich folgende Wirkungsweise ein: Soll das Schloß 1 von der Außenseite her mittels der Außendrehhandhabe 4 betätigt werden, so ist es erforderlich, die mit dem die entsprechende Öffnungscode-Kombination aufweisenden Bereich C versehene Schlüsselkarte 8 in den Einsteckschlitz 7 einzuführen. Sie verlagert dabei die von den Druckfedern 34 beaufschlagte Ankerplatte 33 in Querrichtung. In der vollkommen eingeschobenen Stellung tritt die Schlüsselkarte 8 mit ihrer einschubseitigen Stirnkante 8' vor einen in Richtung des Deckelteils 12 weisenden Schieberanschlag 25'. In dieser Stellung sind die magnetischen Zuhaltungsstifte 31 mittels des Öffnungscode-Kombinationsbereiches C der Schlüsselkarte 8 derart verlagert, daß sie die Löcher 29 der Sperrplatte 26 verlassen. Des weiteren fluchtet das dem Schlüsselkarten-Einschubschacht 35 zugekehrte Ende 63 des Stiftes 62 mit der Ausnehmung 67 der Schlüsselkarte 8. Es kann nun die Weiterbewegung der Schlüsselkarte 8 erfolgen, wobei der Schieber 25 entgegen der Kraft der Zugfeder 36 mitgeschleppt wird. Während dieser Verlagerung bewirkt die Ausnehmung 65 in Verbindung mit dem kegelförmigen Ende 64 eine Aussteuerung des Stiftes 62 derart, daß dieser, wie es Fig. 11 veranschaulicht, in die Ausnehmung 67 der Schlüsselkarte 8 eintaucht. In der vorverlagerten Stellung haben die Rastnasen 60' der Federabschnitte 60 die Anschlagnocken 59 des Schiebers 25 hintergriffen und halten diesen in der vorverlagerten Stellung. Einhergehend mit der Vorverlagerung des Schiebers 25 wurde durch die Abschrägung 40' der Nase 40 der Steg 44 beaufschlagt und die Federzunge 45 um ihre Einspannpunkte verschwenkt. Da sich das freie, gegabelte Ende 48 der Zunge 45 in Eingriff mit der Kupplungshülse 50 befindet, wird diese derart verschoben, daß sie dann auch das Zahnrad 57 übergreift. Da nun beide Zahnräder 51,57 von der Kupplungshülse 50 umfaßt sind, kann mittels der Außendrehhandhabe 4 das Schloß 1 betätigt werden. In der in Fig. 11 veranschaulichten vorverlagerten Stellung tritt der Initiierungs-Bereich I der Schlüsselkarte 8 in den Bereich der Induktionsspulen 69,70, so daß durch die hierdurch bedingten Veränderungen, beispielsweise des Magnetfeldes, Induktionsspannungen in den Induktionsspulen 69,70 erzeugt werden. Diese Induktionsspannungen veranlassen eine Abspeicherung von Daten, insbesondere von Datum und Uhrzeit und eventuell Benutzercode im Speicher S. Anstelle der Induktionsspulen können auch andere Sensoren, z.B. Hall-Sensoren, die auch mehrere magnetische Einzelpunkte des Schlüssels ansprechen, Verwendung finden. Hierbei ist es besonders vorteilhaft, daß erst eine Vorverlagerung des Schiebers 25 nötig ist, um eine Initiierung des Speichers S zu realisieren. Schlüsselkarten 8 mit einem nicht auf das Schloß 1 abgestimmten Öffnungscode-Kombinationsbereich C veranlassen somit keine Speicherung von Daten. Es wird lediglich registriert, wenn die Schlüsselkarte 8 in dem Schloß 1 so weit verlagert worden ist, daß ein Aufschließen der Tür jedenfalls hat stattfinden können. Hierbei kann die Registrierung von beispielsweise zwanzig Einzeldaten derart erfolgen, daß bei Überschreiten dieser Stückzahl die ersten Daten wieder gelöscht und durch die neuen Daten ersetzt werden. Das Abfragen der gespeicherten Daten kann über eine nicht dargestellte Schnittstelle erfolgen und/oder auch über eine Entnahme des Speichers bzw. nur nach einer Entnahme. Er kann dabei auch gegen einen unbenutzten ausgetauscht werden.The following mode of action occurs: If the lock 1 is to be actuated from the outside by means of the external turning handle 4, it is necessary to insert the key card 8 provided with the area C having the corresponding opening code combination into the insertion slot 7. It displaces the anchor plate 33 acted upon by the compression springs 34 in the transverse direction. In the fully inserted position, the key card 8, with its insert-side end edge 8 ', comes in front of a slide stop 25' pointing in the direction of the cover part 12. In this position, the magnetic tumbler pins 31 are shifted by means of the opening code combination area C of the key card 8 such that they leave the holes 29 in the blocking plate 26. Furthermore, the end 63 of the pin 62 facing the key card insertion slot 35 is aligned with the recess 67 of the key card 8. The key card 8 can now be moved further, with the slide 25 being dragged against the force of the tension spring 36. During this displacement, the recess 65, in conjunction with the conical end 64, causes the pin 62 to be driven in such a way that, as illustrated in FIG. 11, it dips into the recess 67 of the key card 8. In the forward position, the latching lugs 60 'of the spring sections 60 engage behind the stop cams 59 of the slide 25 and hold it in the forward position. Along with the forward displacement of the slide 25, the web 44 was acted upon by the bevel 40 'of the nose 40 and the spring tongue 45 was pivoted about its clamping points. Since the free, forked end 48 of the tongue 45 is in engagement with the coupling sleeve 50, this is displaced such that it then also overlaps the gear 57. Since both gear wheels 51, 57 are now encompassed by the coupling sleeve 50, the external turning handle can be used 4 the lock 1 are operated. In the forward position illustrated in FIG. 11, the initiation area I of the key card 8 enters the area of the induction coils 69, 70, so that the resulting changes, for example the magnetic field, generate induction voltages in the induction coils 69, 70. These induction voltages cause data, in particular the date and time and possibly user code, to be stored in memory S. Instead of the induction coils, other sensors, for example Hall sensors, which also address several magnetic individual points of the key can also be used. It is particularly advantageous here that the slide 25 must first be advanced in order to initiate the memory S. Key cards 8 with an opening code combination area C not coordinated with the lock 1 therefore do not cause any storage of data. It is only registered when the key card 8 has been moved so far in the lock 1 that the door can be unlocked in any case. Here, for example, twenty individual data can be registered in such a way that when this number of pieces is exceeded, the first data are deleted again and replaced by the new data. The stored data can be queried via an interface (not shown) and / or via removal of the memory or only after removal. It can also be exchanged for an unused one.

Die Anordnung kann so getroffen sein, daß Induktionsspulen 69,70 im Bereich des Schlüsselkasten-Einschubschachtes 35 vorgesehen sind. Dieser Anordnung entsprechend ist hierbei auch der Initiierungs-Bereich I auf der Schlüsselkarte positioniert. Dessen Magnetfeld kommt also dann auch noch die weitere Funktion des Ein-Schaltens (veranlassen) des Speichers zu. Um lediglich zu registrieren, wenn ein Aufschließen des Schlosses 1 hat stattfinden können, kann auch ein Schalter in dem dem Einsteckschlitz 7 entgegengesetzten Bereich des Schloßkastens 3 angeordnet sein, der erst bei vorverlagerter Stellung des Schiebers 25 den Speicher S zur Datenspeicherung veranlaßt.The arrangement can be such that induction coils 69, 70 are provided in the area of the key box insertion slot 35. In accordance with this arrangement, initiation area I is also positioned on the key card. Whose magnetic field is coming So then also the further function of switching the memory on. In order to register only when unlocking of the lock 1 has taken place, a switch can also be arranged in the area of the lock case 3 opposite the insertion slot 7, which only causes the memory S to store data when the slide 25 is in the forward position.

Beim Abziehen der Schlüsselkarte 8 wird zwangsläufig über den in die Schlüsselkarte 8 eingetretenen Stift 62 der Schieber 25 in die Rückverlagerungs-Endstellung bewegt. Er gelangt dabei in fluchtende Lage zur Ausnehmung 65 und gestattet damit das vollständige Abziehen der Schlüsselkarte 8. Während der Kartenabzugsbewegung wurde auch die Rast zwischen den Anschlagnocken 59 und den Rastnasen 60' der Federzunge 45 überwunden derart, daß erneut die Ausgangsstellung vorliegt. Ebenfalls wurde die Kupplungshülse dadurch zurückverlagert, daß die andere Nase 41 mit ihrer Schrägfläche 41' den Lappen 43 des Steges 44 beaufschlagt und damit auch die Federzunge 45 in ihre Endstellung zurückführt.When the key card 8 is withdrawn, the slider 25 is inevitably moved into the final displacement position via the pin 62 which has entered the key card 8. It thereby comes into alignment with the recess 65 and thus allows the key card 8 to be removed completely. During the card withdrawal movement, the catch between the stop cams 59 and the catch tabs 60 'of the spring tongue 45 was overcome in such a way that the starting position is again present. Likewise, the coupling sleeve was moved back in that the other nose 41 with its inclined surface 41 'acts on the tab 43 of the web 44 and thus also returns the spring tongue 45 to its end position.

Es ist auch möglich, mit dem Speicher den Zeitpunkt des Schlüsselabzugs zur registrieren, um gegebenenfalls sogar die Einschubzeit eines Schlüssels festzuhalten.It is also possible to register the time of the key withdrawal with the memory in order to even record the insertion time of a key if necessary.

Des weiteren besteht die Möglichkeit, eine dem registrierten Schlüsseleinschub nachfolgende Öffnungsbetätigung der Handhabe 4 im Speicher nach Uhrzeit etc. abzulegen, z.B. durch Abfrage der Bewegung des Dornes 56 über eine Schaltscheibe Sch, alles etwa gemäß EP-A 1.364 878. Das hätte auch den Vorteil, daß eine türinnenseitige Schloßbetätigung (ohne Schlüsselbenutzung) nicht entfernt wird, weil der Speicher nicht durch den verlagerten Schieber aktiviert ist.Furthermore, there is the possibility of storing an opening actuation of the handle 4 following the registered key insert in the memory according to the time etc., for example by querying the movement of the mandrel 56 via a switching disk Sch, all according to EP-A 1,364,878. This would also have the advantage that a lock inside the door (without using the key) is not removed is because the memory is not activated by the relocated slider.

Claims (10)

  1. Lock (1) with locking function to be released by inserting a key card (8) which is magnetised in certain areas, in which the key card (8) entrains a slide (25) released by the magnetic pin tumblers (31), characterised by a memory (S) which is initiated in the release position of the slide (25) and which can be put out of operation without eliminating the locking function of the lock and which - in operation - stores codes of the key card in relation to other absolute data, e.g. date and time of the moment of key insertion and/or of the moment of key removal, for a plurality of key insertion processes so as to allow scanning.
  2. Lock according to claim 1 or in particular according thereto, characterised in that the stored codes are formed by a portion of the magnetic areas of the key card (8) not needed for locking.
  3. Lock according to one or more of the preceding claims or in particular according thereto, characterised in that the initiating magnetised areas (initiating areas I) move into their operative position only by displacement of the slide (25).
  4. Lock according to one or more of the preceding claims or in particular according thereto, characterised in that the memory can be removed from the lock while maintaining the locking function of the lock.
  5. Lock according to one or more of the preceding claims or in particular according thereto, characterised in that there is provided a switch which scans the slide (25) and which, in the displaced position of the slide (25), releases the memory (S) for initiation by the magnetised areas (initiating area I).
  6. Lock according to one or more of the preceding claims or in particular according thereto, characterised in that a further portion of the magnetised areas of the key card embodies a user code which the memory registers simultaneously with date and time so as to allow call-up.
  7. Lock according to one or more of the preceding claims or in particular according thereto, characterised in that the memory (S) is supplied by a battery arranged in the lock (1).
  8. Lock according to one or more of the preceding claims or in particular according thereto, characterised in that the activated memory also stores date/time of operation of the exterior handle (4) of the lock so as to allow call-up.
  9. Lock according to one or more of the preceding claims or in particular according thereto, characterised in that the initiating area passes under an induction coil as energy supplier.
  10. Lock according to one or more of the preceding claims or in particular according thereto, characterised in that the memory can be scanned only after removal from the lock.
