Definitions
- the invention relates to a mechanical lock according to the preamble of claim 1.
- Such a mechanical lock is to be improved by the present invention in such a way that its variable key is structurally relatively simple and can be adjusted easily and simply and that the set key or lock combination can be easily memorized.
- the lock shown is constructed exactly the same as the lock described in the already mentioned US-A-4 030 325 except for the differences to be explained.
- Fig. 1 corresponds directly to Fig. 1 of US-A-4 030 325, so that a more detailed description and illustration of the lock should be unnecessary. In this sense, the disclosure of US-A-4 030 325 is expressly to be understood as part of the present description.
- the most important parts of the castle are a housing or stator 1, a main rotor 2, an additional rotor 3, a locking member 4, a number of z. B. ten axially one behind the other key scanning elements 5 and an equally large number of interacting with them transmission elements 6 and a total of 7 designated key, which in the present case is permanently mounted in the lock and rotatably mounted about the lock axis 0.
- the key 7 is rotatably mounted in the end wall 8 of the lock.
- the main components it comprises a number of z. B. ten axially one behind the other cam discs 71a, 71b ... 75a, 75b, which are each rotatably connected to one another in pairs or in one piece.
- the pairs of cams are seated on coaxial hollow shafts 81-85 which are guided through the end wall 8 of the lock and are provided with handwheels 91-95 outside the lock. The individual pairs of cams can be rotated against each other by means of these handwheels.
- Each cam disc forms a key information element and has five different discrete radius levels (FIG. 4), which are scanned by the scanning noses 6d of the transmission elements 6, which are only hinted at in FIG. 2.
- the total variety of variations of the overall key combination is 5 1 °, which in practice should be sufficient for most cases.
- each disc or disc combination has approximately as many different angular positions with different radii or combinations of radii as an alphabet has letters. This then allows the individual angular positions to be identified by the letters of the alphabet and, on the other hand, to manage with relatively few letters (digits) for the entire key combination. Since practically the entire alphabet is available for each angular position, the key combination can very easily be selected in such a way that meaningful words result, which makes it much easier to remember the key combination.
- FIG. 3 shows how the individual angular positions of the pairs of cams 71a, 71b ... 75a, 75b are identified by letters attached to the circumference of the end faces of the handwheels 91-95.
- the each. set key combination is visible through a display window 100.
- the key 7, as already mentioned, is permanently installed in the lock, so that the lock works as a so-called combination lock.
- the key 7 and the lock in such a way that the key can also be removed or inserted, so that the lock then works as an ordinary lock with a socket key.
- “key” is understood to mean that permanently installed or pluggable part which contains the (variable) key information, which is then scanned in the actual lock and compared with the key combination contained therein.
- the lock is preferably a so-called learning lock, just like in US Pat. No. 4,030,325, the lock combination of which can be set to any key information by simple manipulation with the key.
- the operation and operation of such a learning lock is described in detail in US-A-4 030 325 and is exactly the same in the present case.
- each pair of cams 71a, 71b ... 75a, 75b is driven by its own handwheel 91-95.
- the drive or the angle adjustment of the pairs of cams could also be done, for. B. sequentially by means of a single handwheel or the like.
- the set key or lock combination can be easily remembered, the key information or combination can be set easily and can be checked easily, the lock combination can be changed very easily in the case of the learning lock and practically no possibility due to the indirect scanning the acoustic detection of the set lock combination.

Description
Die Erfindung betrifft ein mechanisches Schloss nach dem Oberbegriff von Patentanspruch 1.The invention relates to a mechanical lock according to the preamble of claim 1.
In der US-A-4 030 325 ist ein sogenanntes Lernschloss beschrieben, welches durch bestimmte Manipulationen auf jeden beliebigen Schlüssel aus einer vorgegebenen Mannigfaltigkeit programmiert werden kann. Die Vorteile eines solchen Lernschlosses liegen auf der Hand und kommen noch verstärkt zum Tragen, wenn die zugehörigen Schlüssel selbst ebenfalls veränderbar bzw. verstellbar sind. In der genannten US-A-4 030 325 ist zwar ein solcher variabler Schlüssel beschrieben, jedoch ist dieser in konstruktiver Hinsicht kompliziert und aufwendig und ferner auch relativ umständlich zu verstellen. Ausserdem ist es bei diesem Schlüssel relativ schwierig, die eingestellte Schlüsselinformation oder Schlüsselkombination im Gedächnis zu behalten.In US-A-4 030 325 a so-called learning lock is described, which can be programmed by manipulations on any key from a predetermined variety. The advantages of such a learning lock are obvious and are even more important if the associated keys themselves can also be changed or adjusted. Such a variable key is described in the cited US Pat. No. 4,030,325, but it is structurally complicated and complex and, furthermore, also relatively difficult to adjust. In addition, it is relatively difficult with this key to keep the key information or key combination set in mind.
Durch die vorliegende Erfindung soll nun ein solches mechanisches Schloss dahingehend verbessert werden, dass sein variabler Schlüssel konstruktiv relativ einfach ist und sich leicht und einfach verstellen lässt und dass sich die eingestellten Schlüssel bzw. Schlosskombinationen leicht merken lassen.Such a mechanical lock is to be improved by the present invention in such a way that its variable key is structurally relatively simple and can be adjusted easily and simply and that the set key or lock combination can be easily memorized.
Das erfindungsgemässe Schloss ist im Patentanspruch 1 beschrieben. Bevorzugte Ausführungsformen ergeben sich aus den abhängigen Ansprüchen.The lock according to the invention is described in claim 1. Preferred embodiments result from the dependent claims.
Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen :
- Figur 1 einen teilweise abgebrochenen Schnitt durch das Schloss senkrecht zur Schlossachse,
Figur 2 einen Axialschnitt durch den Schlüssel,- Figur 3 eine Ansicht des Schlüssels in Richtung des Pfeils 111 in Fig. 2 und
- Figur 4 eine Schnittansicht des Schlüssels nach der Linie IV-IV der Fig. 2.
- FIG. 1 shows a partially broken section through the lock perpendicular to the lock axis,
- FIG. 2 shows an axial section through the key,
- Figure 3 is a view of the key in the direction of arrow 111 in Fig. 2 and
- 4 shows a sectional view of the key along the line IV-IV of FIG. 2nd
Das dargestellte Schloss ist bis auf die noch zu erläuternden Unterschiede genau gleich aufgebaut wie das in der schon genannten US-A-4 030 325 beschriebene Schloss. Die Fig. 1 entspricht unmittelbar der Fig. 1 der US-A-4 030 325, so dass sich eine eingehendere Beschreibung und Darstellung des Schlosses erübrigen dürfte. Die Offenbarung der US-A-4 030 325 ist in diesem Sinne ausdrücklich als Bestandteil der vorliegenden Beschreibung zu verstehen.The lock shown is constructed exactly the same as the lock described in the already mentioned US-A-4 030 325 except for the differences to be explained. Fig. 1 corresponds directly to Fig. 1 of US-A-4 030 325, so that a more detailed description and illustration of the lock should be unnecessary. In this sense, the disclosure of US-A-4 030 325 is expressly to be understood as part of the present description.
Die wesentlichsten Teile des Schlosses sind ein Gehäuse oder Stator 1, ein Hauptrotor 2, ein Zusatzrotor 3, ein Verriegelungsorgan 4, eine Anzahl von z. B. zehn axial hintereinander angeordneten Schlüsselabtastelementen 5 und eine ebensogrosse Anzahl von mit diesen zusammenwirkenden Uebertragungsgliedern 6 sowie ein gesamthaft mit 7 bezeichneter Schlüssel, der im vorliegenden Fall fix im Schloss montiert und um die Schlossachse 0 drehbar gelagert ist.The most important parts of the castle are a housing or stator 1, a
Für das Verständnis der Erfindung ist lediglich vonnöten zu wissen, dass bei einer Drehbewegung des Schlüssels 7 während des Öffen- oder Schliessvorgangs die Abtastfinger 5a der Abtastelemente 5 in Anlage mit den Abtastflächen 6a der zugeordneten Uebertragungsglieder 6 kommen und damit via Uebertragungsglieder 6 die im Schlüssel 7 in mechanisch-räumlicher Form enthaltene Schlüsselinformation abtasten. Die Uebertragungsglieder 6 sind mittels eines Bolzens 6b im Hauptrotor 2 schwenkbar gelagert und mittels je einer Feder 6c gegen den Schlüssel 7 gedrückt. Ihre am Ende ausgebildeten Abtastnasen 6d tasten am Schlüssel 7 ausgebildete Kurvenscheiben 71a, 71 b ... 75a, 75b, welche die Schlüsselinformation beinhalten bzw. bilden, ab. Der Aufbau und das Zusammenwirken der übrigen Teile des Schlosses sowie die Funktion desselben sind in der US-A-4 030 325 ausführlich erläutert und sollen daher an dieser Stelle nicht wiederholt werden. Abgesehen von der Ausbildung des Schlüssels besteht der einzige Unterschied zur US-A-4 030 325 lediglich darin, dass dort der Schlüssel direkt durch die Abtastelemente 5 abgetastet wird, während dies im vorliegenden Falle indirekt unter Vermittlung der Uebertragungsglieder 6 erfolgt.To understand the invention, it is only necessary to know that when the key 7 rotates during the opening or closing process, the scanning fingers 5a of the
Wie aus Fig. 2 hervorgeht, ist der Schlüssel 7 in der Stirnwand 8 des Schlosses drehbar gelagert. Er umfasst als wesentlichste Bestandteile eine Anzahl von z. B. zehn axial hintereinander angeordneten Kurvenscheiben 71a, 71 b ... 75a, 75b, die jeweils paarweise untereinander drehfest verbunden oder einstückig sind. Die Kurvenscheibenpaare sitzen auf koaxialen Hohlwellen 81-85, die durch die Schlossstirnwand 8 hindurch geführt und ausserhalb des Schlosses mit Handrädern 91-95 versehen sind. Mittels dieser Handräder können die einzelnen Kurvenscheibenpaare beliebig gegeneinander verdreht werden.As is apparent from Fig. 2, the key 7 is rotatably mounted in the
Jede Kurvenscheibe bildet ein Schlüsselinformationselement und weist fünf verschiedene diskrete Radienniveaus (Fig. 4) auf, die von den in Fig. 2 nur andeutungsweise dargestellten Abtastnasen 6d der Uebertragungsglieder 6 abgetastet werden. Pro Kurvenpaar sind somit fünf mal fünf Radienkombinationen möglich. Entsprechend ist jedes Kurvenpaar in 25 diskrete Winkelstellungen gegenüber einer Bezugsebene, hier z. B. die Zeichenebene, verstellbar, wobei in jeder Winkelstellung eine andere Radienkombination bzw. Informationselementenkombination abgetastet wird. Mit den gezeigten fünf Kurvenpaaren beträgt die totale Variationsvielfalt der Gesamtschlüsselkombination 51°, was in der Praxis für die meisten Fälle ausreichend sein dürfte.Each cam disc forms a key information element and has five different discrete radius levels (FIG. 4), which are scanned by the
Die Anzahl von 5 Radienniveaus oder -abstufungen ist selbstverständlich nicht zwingend, genausowenig wie der Umstand, dass jeweils zwei Scheiben drehfest miteinander verbunden sind. Wesentlich ist lediglich, dass jede Scheibe oder Scheibenkombination (-paar) etwa soviele verschiedene Winkelstellungen mit unterschiedlichen Radien bzw. Radienkombinationen aufweist, wie etwa ein Alphabet Buchstaben hat. Dies erlaubt dann nämlich, die einzelnen Winkelstellungen durch die Buchstaben des Alphabets zu kennzeichnen und anderseits für die gesamte Schlüsselkombination mit relativ wenig Buchstaben (Stellen) auszukommen. Da für jede Winkelstellung praktisch das gesamte Alphabet zur Verfügung steht, kann die Schlüsselkombination sehr leicht so gewählt werden, dass sich sinnvolle Wörter ergeben, was die Merkbarkeit der Schlüsselkombination wesentlich erleichtert.The number of 5 radius levels or gradations is of course not mandatory, ge just as little as the fact that two panes are rotatably connected to each other. It is only essential that each disc or disc combination (pair) has approximately as many different angular positions with different radii or combinations of radii as an alphabet has letters. This then allows the individual angular positions to be identified by the letters of the alphabet and, on the other hand, to manage with relatively few letters (digits) for the entire key combination. Since practically the entire alphabet is available for each angular position, the key combination can very easily be selected in such a way that meaningful words result, which makes it much easier to remember the key combination.
Aus Fig. 3 geht hervor, wie die einzelnen Winkelstellungen der Kurvenscheibenpaare 71a, 71 b ... 75a, 75b durch am Umfang der Stirnflächen der Handräder 91-95 angebrachte Buchstaben gekennzeichnet sind. Die jeweils. eingestellte Schlüsselkombination ist durch ein Anzeigefenster 100 sichtbar.3 shows how the individual angular positions of the pairs of
Im vorliegenden Fall ist der Schlüssel 7, wie schon erwähnt, fix im Schloss montiert, so dass das Schloss als sogenanntes Kombinationsschloss arbeitet. Selbstverständlich ist es ohne weiteres auch möglich, den Schlüssel 7 und das Schloss so auszubilden, dass der Schlüssel auch entfernbar bzw. einsteckbar ist, so dass das Schloss dann als gewöhnliches Schloss mit Steckschlüssel arbeitet. Unter « Schlüssel wird somit in der vorliegenden Beschreibung derjenige fest eingebaute oder steckbare Teil verstanden, welcher die (variable) Schlüsselinformation beinhaltet, die dann im eigentlichen Schloss abgetastet und mit der dort enthaltenen Schlüsselkombination verglichen wird.In the present case, the key 7, as already mentioned, is permanently installed in the lock, so that the lock works as a so-called combination lock. Of course, it is also easily possible to design the key 7 and the lock in such a way that the key can also be removed or inserted, so that the lock then works as an ordinary lock with a socket key. In the present description, “key” is understood to mean that permanently installed or pluggable part which contains the (variable) key information, which is then scanned in the actual lock and compared with the key combination contained therein.
Das hier nicht näher dargestellte und beschriebene Schloss ist mit Vorzug genau wie in der US-A-4 030 325 ein sogenanntes Lernschloss, dessen Schlosskombination durch eine einfache Manipulation mit dem Schlüssel auf jede beliebige Schlüsselinformation eingestellt werden kann. Die Funktions- und Betriebsweise eines solchen Lernschlosses ist in der US-A-4 030 325 genauestens beschrieben und im vorliegenden Falle genau gleich.The lock, not shown and described here, is preferably a so-called learning lock, just like in US Pat. No. 4,030,325, the lock combination of which can be set to any key information by simple manipulation with the key. The operation and operation of such a learning lock is described in detail in US-A-4 030 325 and is exactly the same in the present case.
In dem in Fig. 2 gezeigten Beispiel ist jedes Kurvenscheibenpaar 71a, 71b ... 75a, 75b durch ein eigenes Handrad 91-95 angetrieben. Selbstverständlich liesse sich der Antrieb bzw. die Winkelverstellung der Kurvenscheibenpaare auch z. B. sequentiell mittels eines einzigen Handrads o. ä. verwirklichen.In the example shown in FIG. 2, each pair of
Die wesentlichsten Vorteile des beschriebenen Schlosses bzw. dessen Schlüssels sind leichte Merkbarkeit der eingestellten Schlüssel- bzw. Schlosskombination, bequeme und gut überprüfbare Einstellung der Schlüsselinformation bzw. -kombination, äusserst einfache Umstellung der Schlosskombination im Falle des Lernschlosses und aufgrund der indirekten Abtastung praktisch keine Möglichkeit der akustischen Detektion der eingestellten Schlosskombination.The most important advantages of the lock or its key described are that the set key or lock combination can be easily remembered, the key information or combination can be set easily and can be checked easily, the lock combination can be changed very easily in the case of the learning lock and practically no possibility due to the indirect scanning the acoustic detection of the set lock combination.
