Definitions
- the invention relates to a magnetic card lock with a key card according to the preamble of the main claim.
- Magnetic card locks with key cards have been known for a long time.
- DE-OS 37 02 730 discloses a magnetic card lock with permanent magnets arranged in the key card, the position and polarization of which form the key secret.
- the basic structure of a magnetic card lock is apparent from European patent application 242 142, the lock having an insertion slot for a key card designed as a magnetic card.
- the lock has a displaceable slide into which the magnetic card can be inserted up to a first stop position. If the magnetic key card is correctly coded, this slide can be displaced by an actuation path into a second stop position by further pushing the magnetic card into the lock housing. This relocation results in the release of the locking mechanism.
- In the first stop position, the query position, magnetic tumbler pins of the lock device are moved by interactions with the permanent magnets of the key card assigned to them. A key card with the appropriate key secret can then be shifted to a second stop position, the release position.
- the invention is therefore based on the object of designing a generic key card such that a visual display of the locking mechanism position is provided with simple means.
- the position of the locking mechanism can be determined at any time. If the key card is first inserted into the magnetic card lock up to the first stop position, the query position, then in addition to the first partial surface, there is also the second partial surface, which, for example, in order to be clearly visible from the first partial surface, may have a color different from the first partial surface, visible.
- the locking mechanism position (query position) is immediately recognizable through the visibility of the second partial area. A user can also see from a distance that the locking mechanism is not released. Rather, in order to release the lock, it is necessary to insert the key card into the lock by one actuation path up to the second stop position (release position).
- the second partial area With a key card bearing the correct coding, the second partial area is then no longer visible. An incorrectly coded key card is immediately recognizable in a magnetic card lock designed in this way without the need to actuate the lock, since the second partial area, forming an insertion marking strip, does not disappear.
- the first partial area settles in the direction of insertion into a tapered section. As a result, the user receives information about the correct insertion direction of the key card.
- the tip of the first partial area lies approximately on the transverse line of the key card which corresponds to the release position when the key card is withdrawn. This provides a visual display of the path by which the card must be pulled out until the lock can be actuated, this path being greater than the actuation path.
- a further embodiment of the key card provides for the second partial area to be designed as a strip, the width of which corresponds to the actuation path, and beyond this strip to provide a third, optically separated partial area which, when the key pull-out position leading to the release is reached, fills the gripping opening approximately over the entire surface .
- the second surface area which indicates the interrogation position of the lock, can have gussets that extend on both sides next to the first partial area on the longitudinal edges of the key card, so that they are exposed in the first stop position and largely in the second stop position by the key card insertion rails are covered.
- the second surface area can furthermore have arrows pointing in the direction of insertion, which ends in the query position with their tips in front of the front edge of the gripping opening. This provides the user with additional information which, in the query position, inserts the key card which is inserted in the lock to release the locking mechanism up to the second stop position.
- An important advantage of the invention is that it makes it possible to do this without changing existing locks, to provide this subsequently with a visual display, the key card being used in addition to the function of carrying the key secret, also as a kind of dipstick to indicate the position of the slide inside the lock and thus its locking mechanism position.
- the key card 8 shown in FIGS. 1-5 has a region 100 which is clearly visible.
- This first partial surface 100 is preceded by a second partial surface 101, which extends from one longitudinal edge across the card surface to the other longitudinal edge, interrupted by a tapering section of the first partial surface 100.
- the upper edge 102 of the second partial surface is arranged such that, in particular 5, it is aligned with the front edge 106 of the gripping opening 107 when the key card is inserted up to the release position.
- the rotary knob 4 is coupled to the actuating mandrel 49 by a displacement of the coupling sleeve 46.
- the gussets 108, 109 of the second partial surface 101 are arranged on both sides of the first partial surface so that they are visible in this position and are largely covered by the insertion rails 104, 105 when the key card is inserted until the release position.
- the base line 103 of the second partial surface is positioned such that it is aligned with the end edge 106 of the gripping opening 107 when the key card is inserted up to the query position.
- the second partial surface 101 has arrows 110, 111 on both sides of the section of the first partial surface 100 which interrupts it and which point in the insertion direction and whose tip ends in front of the base line 103.
- the tip 104 of the section of the first partial surface 100 which tapers in the direction of insertion of the card is in alignment with the end edge 106 of the gripping opening 107 when the key card 8 is pulled out the release position of the lock is canceled.
- the rotary knob 4 is then uncoupled from the actuating mandrel 49 by moving the coupling sleeve 46.
- the magnetic card lock 1 shown in FIGS. 6-9 has a lock case 3, which is fixed on the outside of the door and has a rectangular outline, which has an external turning handle 4 at one end, with the aid of which a bolt or a latch, not shown, can be withdrawn.
- the lock case 3 is provided at the other end with an insertion slot 7 for a key card 8 magnetized in some areas.
- the lock case 3 receives a housing 9 which has a cover 13 which is fixed to the housing 9 by means of screws 16.
- a slider 17 made of plastic and in the form of a plate is guided.
- the guide surface opposite the cover 13 forms a perforated plate 18 made of brass, which is inserted into the housing 9 from the cover side.
- the holes 20 of the perforated plate 18 are aligned in the position (locking position) of the lock 1 shown in FIG. 6 with corresponding bearing recesses 21 of the slide 17, which holes are designed as through holes of the slide.
- Magnetic tumbler pins 22 are located in the bearing recesses 21. It is not necessary to provide a tumbler pin 22 in each bearing recess 21, since the number, the position and the polarity of the tumbler pins 22 depend on the respective locking secret of the lock 1.
- the perforated plate 18 On the perforated plate 18 is a copper baffle 23, which is opposite an anchor plate 24. The latter will held in position by compression springs.
- the anchor plate 24 In contrast to the other components, the anchor plate 24 consists of ferromagnetic material. The anchor plate 24 thus attracts the magnetic tumbler pins 22, as a result of which they engage in the holes 20 in the perforated plate 18. In this position, the slide 17 cannot be shifted from its basic position illustrated in FIG. 6, since the engagement of the tumbler pins 22 in the perforated plate 18 fixed to the housing prevents this.
- Both the anchor plate 24 and the guide plate 23 connect to the insertion slot 7 of the lock case 3. Their opposite wall surfaces form the key card slot 30.
- a tension spring 33 serving as a return spring is fixed at one end to a cross pin 34 of the cover 13.
- the other end of the tension spring 33 engages on a projection 35 of the slide 17.
- the bevel 38 of the nose 36 of the slide 17 is designed in the same direction. It engages on the inclined surface 40 of a web 42 of a tongue 43 made of spring material. The latter is positively embedded on the top of the cover 13 and fixed with the cover screws 16.
- the inclined surface 40 of the web 42 is formed by a bend which is directed away from the bevel 38 and extends in the immediate vicinity in the basic position, cf. Fig. 6.
- the tongue 43 engages with its fork-shaped free end 44 in an annular groove 45 of a coupling sleeve 46.
- the latter is internally toothed.
- a coupling sleeve 46 According to the uncoupled basic position, cf. Fig. 6, includes the coupling sleeve 46 exclusively a gear 47.
- the bearing sleeve 48 is rotatably supported in a lock case base plate 50.
- the bearing sleeve 48 is secured against being pulled off by a radially outwardly directed collar 48 ′ provided on it, which is supported on the inside of the lock case base plate 50.
- a gear 51 is located opposite the gear 47.
- Both gears 47, 51 are identical in their teeth and adapted to the inner teeth of the coupling sleeve 46.
- the gear 51 in turn is, however, firmly connected to the external turning handle 4.
- a central pin 52 is used to stabilize the position of the gear wheels 47, 51, but does not influence the rotatability of the gear wheels 47, 51.
- the length of the gear 47 corresponds approximately to that of the coupling sleeve 46. In the uncoupled position, the inner end of the coupling sleeve 46 ends in front of the facing end of the gear 51. A rotational displacement of the external turning handle therefore does not lead to entrainment of the gear 47 and thus the square pin 49.
- the slider 17 can be locked in its forward position (release position).
- Resilient locking cams 70 which are formed by locking hooks 41, serve for locking transversely to the slide displacement.
- the latter are rotatably mounted about an axis 39 in the slide 17.
- Uncoupling requires the key card 8 to be withdrawn. After a partial displacement, the key card releases the latching hook 41 so that it can withdraw under the spring 71, the latching being released.
- the return spring 33 tensioned during the forward displacement pulls the slide 17 back into its basic position. This is also associated with a displacement of the coupling sleeve 46 into the decoupling position.

Abstract
Description
Die Erfindung betrifft ein Magnetkartenschloß mit Schlüsselkarte gemäß Gattungsbegriff des Hauptanspruches.The invention relates to a magnetic card lock with a key card according to the preamble of the main claim.
Magnetkartenschlösser mit Schlüsselkarten sind seit langem bekannt. So offenbart die DE-OS 37 02 730 ein Magnetkartenschloß mit in der Schlüsselkarte angeordneten Permanentmagneten, deren Position und Polarisation das Schlüsselgeheimnis bilden. Der grundsätzliche Aufbau eines Magnetkartenschlosses geht aus der europäischen Patentanmeldung 242 142 hervor, wobei das Schloß einen Einsteckschlitz für eine als Magnetkarte ausgebildete Schlüsselkarte aufweist. Das Schloß weist dabei einen verlagerbaren Schieber auf, in den die Magnetkarte bis zu einer ersten Anschlagstellung einsteckbar ist. Bei richtiger Codierung der magnetischen Schlüsselkarte ist dieser Schieber durch weiteres Hereindrücken der Magnetkarte in das Schloßgehäuse, um einen Betätigungsweg bis in eine zweite Anschlagstellung verlagerbar. Diese Verlagerung bewirkt die Freigabe des Schließwerks. In erster Anschlagstellung, der Abfragestellung werden magnetische Zuhaltungsstifte des Schloßeingerichtes durch Wechselwirkungen mit den ihnen zugeordneten Permanetmagneten der Schlüsselkarte bewegt. Eine Schlüsselkarte mit passendem Schlüsselgeheimnis läßt sich dann bis in eine zweite Anschlagstellung, der Freigabestellung verlagern.Magnetic card locks with key cards have been known for a long time. For example, DE-OS 37 02 730 discloses a magnetic card lock with permanent magnets arranged in the key card, the position and polarization of which form the key secret. The basic structure of a magnetic card lock is apparent from European patent application 242 142, the lock having an insertion slot for a key card designed as a magnetic card. The lock has a displaceable slide into which the magnetic card can be inserted up to a first stop position. If the magnetic key card is correctly coded, this slide can be displaced by an actuation path into a second stop position by further pushing the magnetic card into the lock housing. This relocation results in the release of the locking mechanism. In the first stop position, the query position, magnetic tumbler pins of the lock device are moved by interactions with the permanent magnets of the key card assigned to them. A key card with the appropriate key secret can then be shifted to a second stop position, the release position.
Um Fehlschaltungen zu vermeiden und um sicherzustellen, ob ein richtig codierter Schlüssel oder ein falsch codierter Schlüssel eingesteckt wurde, ist es daher wünschenswert, vom Schloß eine Information darüber zu erhalten, in welcher Schließstellung es sich befindet.In order to avoid incorrect switching and to ensure whether a correctly coded key or an incorrectly coded key has been inserted, it is therefore desirable to receive information from the lock on the locking position in which it is.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine gattungsgemäße Schlüsselkarte so auszugestalten, daß mit einfachen Mitteln eine Sichtanzeige der Schließwerkstellung gegeben ist.The invention is therefore based on the object of designing a generic key card such that a visual display of the locking mechanism position is provided with simple means.
Gelöst wird die Aufgabe durch die kennzeichnenden Merkmale des Hauptanspruches.The task is solved by the characteristic features of the main claim.
Die Unteransprüche stellen vorteilhafte Weiterbildungen dar.The subclaims represent advantageous developments.
Zufolge eines derartig ausgestalteten Magnetkartenschlosses mit Schlüsselkarte ist die Stellung des Schließwerkes jederzeit feststellbar. Wird die Schlüsselkarte zunächst bis in die erste Anschlagstellung, der Abfragestellung in das Magnetkartenschloß eingeschoben, so ist neben der ersten Teilfläche auch die zweite Teilfläche, die beispielsweise, um sich von der erste Teilfläche sichtbar abzusetzen, eine von der ersten Teilfläche abweichende Farbe aufweisen kann, sichtbar. Die Schließwerkstellung (Abfragestellung) ist durch die Sichtbarkeit der zweiten Teilfläche sofort erkennbar. Ein Benutzer kann auch von weitem feststellen, daß das Schließwerk nicht freigegeben ist. Um eine Freigabe des Schlosses zu erzielen, ist es vielmehr notwendig, die Schlüsselkarte um einen Betätigungsweg bis zur zweiten Anschlagstellung (Freigabestellung) in das Schloß einzuschieben. Bei einer die richtige Codierung tragenden Schlüsselkarte ist dann die zweite Teilfläche nicht mehr sichtbar. Eine falsch codierte Schlüsselkarte ist bei einem derartig ausgestalteten Magnetkartenschloß sofort erkennbar, ohne daß eine Schloßbetätigung erfolgen muß, da die zweite Teilfläche, einen Einschubmarkierungsstreifen bildend, nicht verschwindet. Gemäß einer weiteren vorteilhaften Ausbildung setzt sich die erste Teilfläche in Einschubrichtung in einen spitz zulaufenden Abschnitt fort. Der Benutzer erhält hierdurch eine Information über die richtige Einschubrichtung der Schlüsselkarte. Die Spitze der ersten Teilfläche liegt dabei etwa auf derjenigen Querlinie der Schlüsselkarte, die beim Herausziehen der Schlüsselkarte im Moment der Aufhebung der Freigabe-Stellung entspricht. Hierdurch ist eine Sichtanzeige des Weges gegeben, um den die Karte bis zur Aufhebung der Schloßbetätigbarkeit herausgezogen werden muß, wobei dieser Weg größer ist als der Betätigungsweg. Eine weitere Ausgestaltung der Schlüsselkarte sieht vor, die zweite Teilfläche als Streifen auszugestalten, deren Breite dem Betätigungsweg entspricht, und jenseits dieses Streifens eine dritte, optisch abgesetzte Teilfläche vorzusehen, welche bei Erreichen der zur Aufhebung der Freigabe führenden Schlüssel-Auszugsstellung etwa vollflächig die Greiföffnung ausfüllt. Auch hierdurch wird die Aufhebung der Freigabe des Schlosses optisch angezeigt. Der zweite Flächenbereich, der die Abfragestellung des Schlosses anzeigt, kann gemäß einer weiteren Ausgestaltung Zwickel aufweisen, die sich beiderseits neben der ersten Teilfläche an den Längskanten der Schlüsselkarte erstrecken, so daß sie in der ersten Anschlagstellung freiliegen und in der zweiten Anschlagstellung von den Schlüsselkarteneinsteckschienen weitestgehend überdeckt sind. Der zweite Flächenbereich kann ferner in Einsteckrichtung weisende Pfeile aufweisen, die in Abfragestellung mit ihren Spitzen vor der Stirnkante der Greiföffnung enden. Hierdurch ist dem Benutzer eine zusätzliche Information gegeben, die in Abfragestellung im Schloß einsteckende Schlüsselkarte weiter zur Freigabe des Schließwerkes bis zur zweiten Anschlagstellung einzuschieben. Ein bedeutender Vorteil der Erfindung liegt darin, daß es hierdurch möglich ist, ohne eine Änderung an vorhandenen Schlössern vorzusehen, diese nachträglich mit einer Sichtanzeige zu versehen, wobei die Schlüsselkarte neben der Funktion, das Schlüsselgeheimnis zu tragen, auch noch als eine Art Peilstab verwendet wird, um die Position des Schiebers im Inneren des Schlosses und damit dessen Schließwerkstellung anzuzeigen.As a result of a magnetic card lock designed in this way with a key card, the position of the locking mechanism can be determined at any time. If the key card is first inserted into the magnetic card lock up to the first stop position, the query position, then in addition to the first partial surface, there is also the second partial surface, which, for example, in order to be clearly visible from the first partial surface, may have a color different from the first partial surface, visible. The locking mechanism position (query position) is immediately recognizable through the visibility of the second partial area. A user can also see from a distance that the locking mechanism is not released. Rather, in order to release the lock, it is necessary to insert the key card into the lock by one actuation path up to the second stop position (release position). With a key card bearing the correct coding, the second partial area is then no longer visible. An incorrectly coded key card is immediately recognizable in a magnetic card lock designed in this way without the need to actuate the lock, since the second partial area, forming an insertion marking strip, does not disappear. According to a further advantageous embodiment, the first partial area settles in the direction of insertion into a tapered section. As a result, the user receives information about the correct insertion direction of the key card. The tip of the first partial area lies approximately on the transverse line of the key card which corresponds to the release position when the key card is withdrawn. This provides a visual display of the path by which the card must be pulled out until the lock can be actuated, this path being greater than the actuation path. A further embodiment of the key card provides for the second partial area to be designed as a strip, the width of which corresponds to the actuation path, and beyond this strip to provide a third, optically separated partial area which, when the key pull-out position leading to the release is reached, fills the gripping opening approximately over the entire surface . This also shows that the release of the lock has been canceled. According to a further embodiment, the second surface area, which indicates the interrogation position of the lock, can have gussets that extend on both sides next to the first partial area on the longitudinal edges of the key card, so that they are exposed in the first stop position and largely in the second stop position by the key card insertion rails are covered. The second surface area can furthermore have arrows pointing in the direction of insertion, which ends in the query position with their tips in front of the front edge of the gripping opening.

Die in Fig. 1 - Fig. 5 dargestellte Schlüsselkarte 8 weist einen sichtbar abgesetzten Bereich 100 auf. Dieser ersten Teilfläche 100 ist eine zweite Teilfläche 101 vorgelagert, die sich von einer Längskante quer über die Kartenoberfläche zur anderen Längskante erstreckt, unterbrochen von einem spitz zulaufenden Abschnitt der ersten Teilfläche 100. Die Oberkante 102 der zweiten Teilfläche ist so angeordnet, daß, wie insbesondere in Fig. 5 dargestellt, sie bei bis zur Freigabestellung eingeschobener Schlüsselkarte mit der Stirnkante 106 der Greiföffnung 107 fluchtet. In dieser Stellung ist der Drehknauf 4 durch eine Verlagerung der Kupplungshülse 46 mit dem Betätigungsdorn 49 gekuppelt. Die Zwickel 108, 109 der zweiten Teilfläche 101 sind beiderseits der ersten Teilfläche so angeordnet, daß sie in dieser Stellung sichtbar sind und bei bis zur Freigabestellung eingeschobener Schlüsselkarte weitgehend durch die Einsteckschienen 104, 105 überdeckt werden. Die Basislinie 103 der zweiten Teilfläche ist derart positioniert, daß sie bei bis zur Abfragestellung eingeschobener Schlüsselkarte mit der Stirnkante 106 der Greiföffnung 107 fluchtet.The
Die zweite Teilfläche 101 weist beidseitig von dem sie unterbrechenden spitz zulaufenden Abschnitt der ersten Teilfläche 100 Pfeile 110, 111 auf, die in Einsteckrichtung weisen und mit ihrer Spitze vor der Basislinie 103 enden.The second
Die Spitze 104 des in Einschubrichtung der Karte spitz zulaufenden Abschnittes der ersten Teilfläche 100 fluchtet in dem Moment mit der Stirnkante 106 der Greiföffnung 107, wenn beim Herausziehen der Schlüsselkarte 8 die Freigabestellung des Schlosses aufgehoben wird. Der Drehknauf 4 wird dann durch Verlagerung der Kupplungshülse 46 von dem Betätigungsdorn 49 entkuppelt.The
Das in Fig. 6 - 9 dargestellte Magnetkartenschloß 1 besitzt einen türaußenseitig festgelegten Schloßkasten 3 rechteckigen Grundrisses, welcher an seinem einen Ende eine Außendrehhandhabe 4 lagert, mit deren Hilfe ein nicht dargestellter Riegel oder eine Falle zurückgezogen werden kann. Der Schloßkasten 3 ist an dem anderen Ende mit einem Einsteckschlitz 7 für eine bereichsweise magnetisierte Schlüsselkarte 8 versehen.The
Der Schloßkasten 3 nimmt ein Gehäuse 9 auf, das einen Deckel 13 aufweist, der mittels Schrauben 16 am Gehäuse 9 festgelegt ist.The
An der Deckelunterseite ist ein aus Kunststoff bestehender, plattenförmig gestalteter Schieber 17 geführt. Die dem Deckel 13 gegenüberliegende Führungsfläche bildet eine aus Messing gefertigte Lochplatte 18, die von der Deckelseite her in das Gehäuse 9 eingelegt ist. Die Löcher 20 der Lochplatte 18 fluchten in der in Fig. 6 dargestellten Lage (Verriegelungslage) des Schlosses 1 mit entsprechenden Lagerausnehmungen 21 des Schiebers 17, welche Löcher als durchgehende Bohrungen des Schiebers ausgebildet sind. In den Lagerausnehmungen 21 liegen magnetische Zuhaltestifte 22 ein. Es ist nicht notwendig, in jeder Lagerausnehmung 21 einen Zuhaltungsstift 22 vorzusehen, da sich die Anzahl, die Lage und die Polarität der Zuhaltungsstifte 22 nach dem jeweiligen Schließgeheimnis des Schlosses 1 richtet.On the underside of the lid, a
Auf der Lochplatte 18 liegt ein kupfernes Leitblech 23, dem eine Ankerplatte 24 gegenüberliegt. Letztere wird von Druckfedern in Position gehalten. Die Ankerplatte 24 besteht im Gegensatz zu den anderen Bauelementen aus ferromagnetischem Material. Mithin zieht die Ankerplatte 24 die magnetischen Zuhaltungsstifte 22 an, wodurch sie in die Löcher 20 der Lochplatte 18 eingreifen. In dieser Lage kann der Schieber 17 nicht aus seiner in Fig. 6 veranschaulichten Grundstellung verschoben werden, da der Eingriff der Zuhaltungsstifte 22 in die gehäusefeste Lochplatte 18 dieses verhindert.On the
Sowohl die Ankerplatte 24 als auch das Leitblech 23 schließen sich an den Einsteckschlitz 7 des Schloßkastens 3 an. Ihre einander gegenüberliegende Wandflächen bilden den Schlüsselkartenschacht 30.Both the
Eine als Rückholfeder dienende Zugfeder 33 ist mit Ihrem einen Ende an einem Querzapfen 34 des Deckels 13 festgelegt. Das andere Ende der Zugfeder 33 greift an einem Vorsprung 35 des Schiebers 17 an. Dadurch wird der Schieber in eine in Fig. 6 anschlagbegrenzte Grundstellung (Verriegelungslage) bewegt. Die Abschrägung 38 der Nase 36 des Schiebers 17 ist gleichläufig gestaltet. Sie greift an der Schrägfläche 40 eines Steges 42 einer aus Federmaterial bestehenden Zunge 43 an. Letztere ist an der Oberseite des Deckels 13 formschlüssig eingelagert und mit den Deckelschrauben 16 fixiert. Die Schrägfläche 40 des Steges 42 ist dabei von einer Abwinklung gebildet, welche von der Abschrägung 38 weggerichtet ist und sich in Grundstellung in der unmittelbaren Nähe erstreckt, vgl. Fig. 6.A
Die Zunge 43 greift mit ihrem gabelförmig gestalteten freien Ende 44 in eine Ringnut 45 einer Kupplungshülse 46 ein. Letztere ist innenverzahnt. Gemäß der entkuppelten Grundstellung, vgl. Fig. 6, umfaßt die Kupplungshülse 46 ausschließlich ein Zahnrad 47. Dieses setzt sich in einer Lagerhülse 48 mit dem Vierkantzapfen 49 fort, der mit einem Türschloß gekoppelt ist. Die Lagerhülse 48 ist drehbar in einer Schloßkastenbodenplatte 50 gelagert. Eine Abzugssicherung erhält die Lagerhülse 48 durch einen an ihr vorgesehenen, radial auswärtsgerichteten Kragen 48', welcher sich an der Innenseite der Schloßkastenbodenplatte 50 abstützt. Dem Zahnrad 47 liegt ein Zahnrad 51 gegenüber. Beide Zahnräder 47, 51 sind in ihrer Zahnung gleich gestaltet und der Innenzahnung der Kupplungshülse 46 angepaßt. Das Zahnrad 51 seinerseits ist jedoch fest mit der Außendrehhandhabe 4 verbunden. Zur Lagenstabilisierung der Zahnräder 47, 51 zueinander dient ein mittlerer Stift 52, der die Drehbarkeit der Zahnräder 47, 51 jedoch nicht beeinflußt. Das Zahnrad 47 entspricht in seiner Länge etwa derjenigen der Kupplungshülse 46. In entkuppelter Stellung endet die innere Stirnseite der Kupplungshülse 46 vor der zugekehrten Stirnseite des Zahnrades 51. Eine Drehverlagerung der Außendrehhandhabe führt daher zu keiner Mitnahme des Zahnrades 47 und damit das Vierkantzapfens 49.The
Der Schieber 17 ist in seiner vorverlagerten Stellung (Freigabestellung) verrastbar. Zur Verrastung dienen quer zur Schieberverlagerung einfedernde Rastnocken 70, die von Rasthaken 41 gebildet werden. Letztere sind um eine Achse 39 im Schieber 17 drehbar gelagert.The
Zwecks Betätigung des Schlosses von außen her mittels der Außendrehhandhabe 4 ist es erforderlich, die entsprechend codierte Schlüsselkarte 8 in den Einsteckschlitz 7 einzuführen. Sie verlagert dabei die von den Druckfedern beaufschlagte Ankerplatte 24 in Querrichtung. Die bis zur ersten Anschlagstellung eingeschobene Schlüsselkarte 8 tritt mit ihrer Stirnkante 8' vor den Mitnehmervorsprung 69 des Schiebers 17. Ferner sind durch die magnetisierten Bereiche die magnetischen Zuhaltungstifte 22 derart verlagert worden, daß sie die Löcher 20 der Lochplatte 18 verlassen. Sodann sind bei der Einschubbewegung die in den Karteneinsteckweg ragenden Rasthaken 41 beaufschlagt worden, wobei diese entsprechend in Querrichtung verlagert werden derart, daß dann die Rastnokken 70 in Öffnungen des Deckels 13 ragen. Bei der anschließenden Weiterbewegung der Schlüsselkarte 8 um den Betätigungsweg in die Freigabestellung wird der Schieber 17 entgegen der Kraft der Zugfeder 33 verlagert. Die Rastnocken 70 unterlaufen dabei den federnden Anschlag einer Blattfeder 71. Sobald die Rastnocken 70 die Feder 71 vollständig unterlaufen haben, sind diese festgelegt (Fig. 8). Der Schieber 17 ist dadurch gegen eine Rückverlagerung verrastet.For the purpose of actuating the lock from the outside by means of the
Einhergehend mit der Vorverlagerung des Schiebers 17 wird durch die Abschrägung 38 der Nase 36 die Schrägfläche 40 des Steges 42 verlagert. Die Kupplungshülse 46 wird in die in Fig. 8 dargestellte Mitnahmestellung verlagert. Beide Zahnräder 47, 51 werden von der Kupplungshülse 46 umfaßt. Mittels der Außendrehhandhabe 4 kann ein Türschloß betätigt werden.Along with the forward displacement of the
Das Entkuppeln verlangt den Abzug der Schlüsselkarte 8. Nach einer Teilverlagerung gibt die Schlüsselkarte den Rasthaken 41 frei, so daß dieser unter die Feder 71 zurücktreten kann, wobei die Verrastung aufgehoben wird. Die bei der Vorverlagerung gespannte Rückholfeder 33 zieht den Schieber 17 in seine Grundstellung zurück. Damit verbunden ist ebenfalls eine Zurückverlagerung der Kupplungshülse 46 in die Entkupplungsstellung.Uncoupling requires the
Claims (5)
- Magnetic card lock with a key card (8) which can be inserted in an insertion shaft (30) which is provided with key card insertion rails and widens at the upper end into a gripping opening, wherein the key card (8) can first be inserted as far as a first stop position, in which position the key code is scanned, and wherein a key card having the correct key code in the form of magnetised zones of one broadside surface of the key card can then be displaced over an operating distance as far as a second stop position, in which position release of the locking mechanism is obtained and wherein this release position can be cancelled only by withdrawal of the key card, characterised in that the broadside surface of the key card comprising magnetised key code zones forms, at its end facing away from the direction of insertion, a first, visibly reduced partial surface (100) which fills the area of the gripping opening (107) in the second stop position and in front of which, in the direction of insertion, is a second partial surface (101) which is visibly reduced in a different fashion and which in the first stop position of the key card (8) forms an insertion marking strip between the lower edge (102) of the first partial surface (100) and the end edge (106) of the gripping opening (107).
- Key card according to claim 1, characterised in that the first partial surface (100) of the key card (8) continues in the direction of feed-in of the card into a tapering section of which the point (104) is approximately located on the transverse line of the key card which is aligned with the end edge (106) of the gripping opening (107) at the moment of cancellation of the release position on withdrawal of the key card.
- Key card according to one or more of the preceding claims, characterised in that on both sides adjacent to the first partial surface (100) are provided gussets (108, 109) which in the first stop position are exposed and in the second stop position are largely covered by the key card insertion rails (104, 105).
- Key card according to one or more of the preceding claims, characterised in that the second partial surface (101) bears arrows (110, 111) which point in the direction of insertion and which in the second stop position end with their point (104) in front of the end edge (106) of the gripping opening (107).
- Key card according to one or more of the preceding claims, characterised in that the second partial surface (101) is designed as a strip of the width of the operating distance between first and second stop positions, and beyond the strip extends a third, optically reduced partial surface which, on reaching the key card withdrawal position leading to cancellation of release, fills more or less the whole area of the gripping opening.
