Abstract

The setting buttons are in a rectangular pattern in the housing, and control a handle-operated bolt. Four bearing bushes (1g, 1i) on the housing bottom (1e) each accommodate a basic gear with n teeth and containing a radial groove at the periphery for a pin on the stop, which is mounted between the gears. Locking washers mounted on the gears have square holes by which they fit on square button spindles, there being the same number of figures on the buttons as the gear teeth. The axial bore in each gear contains a pin with tapering ends engaging in taper bores (6a - d) in a changeover plate (6) and in others in the locking washer, and which are the same in number as the gear teeth.

Description

Technisches GebietTechnical field

Die Erfindung betrifft ein Kombinationsschloß mit vier Einstellknöpfen, die im Schloßkasten in einem Rechteck angeordnet sind, und einer Handhabe, die einen von den Einstellknöpfen gesteuerten Riegel antreibt.The invention relates to a combination lock with four adjusting buttons, which are arranged in the lock case in a rectangle, and a handle that drives a bolt controlled by the adjusting buttons.

Stand der TechnikState of the art

Kombinationsschlösser mit vier Einstellknöpfen sind als leichte Koffer- oder oder Schrankschlösser bekannt geworden.Combination locks with four adjustment knobs have become known as light suitcase or cabinet locks.

Die europäische Patentschrift 0139026 offenbart ein Kombinationsschloß mit drei Kodierungsknöpfen, die in der Schloßachse hintereinander liegen. Die benutzten Sperrscheiben weisen diametrale Sperrschieber auf, die in einem Umstellschieber geführt sind. Dieses Schloß wurde mit drei Knöpfen zu je 26 Einstellpositionen verwirklicht, so daß 26³ = 42875 Kombinationen möglich sind. Bei dieser Ausführungsform ergeben sich sehr kleine Winkelschritte, so daß eine hohe Fertigungspräzision erforderlich ist.European patent specification 0139026 discloses a combination lock with three coding buttons which lie one behind the other in the lock axis. The locking washers used have diametrical locking slides, which are guided in a change-over slide. This lock was realized with three buttons with 26 setting positions each, so that 26³ = 42875 combinations are possible. In this embodiment, there are very small angular steps, so that high manufacturing precision is required.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ein Kombinationsschloß mit einer vergleichbar hohen Zahl von Kombinationen zu schaffen, das preisgünstig herstellbar und trotzdem in hohem Maße manipulationssicher ist.The invention has for its object to provide a combination lock with a comparably high number of combinations, which can be manufactured inexpensively and is nevertheless highly tamper-proof.

Diese Aufgabe wird erfindungsgemäß mit den im Kennzeichen des Anspruches angegebenen Mitteln gelöst.This object is achieved with the means specified in the characterizing part of the claim.

Ein Ausführungsbeispiel der Erfindung wird anhand von Fig. 1 und 2 erläutert.

Fig. 1a, 1b
zeigt das Schloß in einer Explosionszeichnung,
Fig. 2

An embodiment of the invention is explained with reference to FIGS. 1 and 2.
1a, 1b
shows the castle in an exploded view,
Fig. 2
the bottom of the lock bolt.

Mit 1 ist der Schloßkasten bezeichnet, der vorzugsweise aus einem formstabilen Thermoplast gespritzt ist. In den vier Ecken sind Führungsrohre 1a, 1b, 1c, 1d für die Befestigungsschrauben angeformt. Der Schloßkastenboden 1e trägt vier eingespritzte Lagerhülsen 1f, 1g, 1h, 1i zur Lagerung der drehbaren Teile. Ein weiterer Lagerdorn 1k ist zwischen den Lagerhülsen angeordnet.With 1 the lock case is designated, which is preferably injection molded from a dimensionally stable thermoplastic. Guide tubes 1a, 1b, 1c, 1d for the fastening screws are formed in the four corners. The lock case base 1e carries four injected bearing sleeves 1f, 1g, 1h, 1i for storing the rotatable parts. Another bearing mandrel 1k is arranged between the bearing sleeves.

Der größte Teil des Schloßgehäuses wird von der Kombinationsmechanik ausgefüllt. Im rechten Teil befindet sich ein Doppelbartumstellschloß mit einem Notriegel, der das Öffnen bei vergessener Kombinations ermöglicht.Most of the lock housing is filled by the combination mechanism. In the right part there is a double-bit change lock with an emergency bolt, which enables opening if the combination is forgotten.

Unmittelbar auf dem Schloßkastenboden 1e liegt eine Steuernuß 2 mit einer Vierkantaussparung, ein Stellschieber 3 und ein Umstellriegel 4. Über der Steuernuß 2 ist der Schloßriegel 5 gelagert. Eine Umstellplatte 6 ist auf dem Dorn 1k schwenkbar gelagert. Sie weist eine Reihe von ovalen Durchbrüchen auf, die u.a. die Lagerhülsen 1f, 1g, 1h, 1i umgreifen. Auf diese Hülsen werden vier Basisscheiben 7, 8, 9, 10 aufgeschoben. Zwischen den Basisscheiben liegt eine kreuzförmige Abtastsperre 11, ferner ein Abtasthebel 12.Directly on the lock case base 1e is a control nut 2 with a square recess, an adjusting slide 3 and a change-over bolt 4. The lock bolt 5 is mounted over the control nut 2. A changeover plate 6 is pivotally mounted on the mandrel 1k. It has a series of oval openings, which include encompass the bearing sleeves 1f, 1g, 1h, 1i. Four base plates 7, 8, 9, 10 are pushed onto these sleeves. A cruciform scanning lock 11 and a scanning lever 12 lie between the base disks.

Vier Rastscheiben 13, 14, 15, 16 mit Innenvierkantöffnung sind einerseits in den Basisscheiben 7 - 10 geführt und andererseits in der Schloßdecke 17 gelagert. Eine federnde Einstellraste 18 sorgt dafür, daß die Rastscheiben immer um volle Schritte verstellt werden.Four locking disks 13, 14, 15, 16 with an internal square opening are guided on the one hand in the base disks 7-10 and on the other hand mounted in the lock cover 17. A resilient adjustment catch 18 ensures that the locking disks are always adjusted by full steps.

Die zugehörigen Einstellknöpfe mit Vierkantwellen und Buchstaben und/oder Zahlensymbolen sind nicht dargestellt.The associated setting knobs with square shafts and letters and / or number symbols are not shown.

Zum Doppelbartumstellschloß gehört außer dem Umstellriegel 4 der Notriegel 19, ein Wirbel 20, eine Zuhaltung 0 mit der Nummer 21 und ein Satz von Zuhaltungen 1, von denen aber nur eine (22) dargestellt ist.In addition to the reversing bolt 4, the double-bit reversing lock includes the emergency bolt 19, a swivel 20, a tumbler 0 with the number 21 and a set of tumblers 1, of which only one (22) is shown.

Das Doppelbartschloß entspricht dem Stande der Technik, so daß sich weitere Ausführungen zu seiner Funktion erübrigen. Wichtig ist hier nur, daß ein Dorn 19a des Notriegels 19 den Abtasthebel 12 freigibt, der die Abtastung der (vergessenen) Kombination erlaubt.The double-bit lock corresponds to the state of the art, so that further explanations of its function are unnecessary. It is only important here that a mandrel 19a of the emergency bolt 19 releases the scanning lever 12, which allows the scanning of the (forgotten) combination.

Protection against manipulation
D:
The emergency opening system

A: Das ZuhaltungssystemA: The locking system

Der Riegel 5 weist an seiner Unterseite einen Tourstiftkanal 5a auf, wie sich aus Fig. 2 ergibt. Der Riegel 5 kann nur dannmit Hilfe der Steuernuß 2 zurückgezogen werden, wenn der Quader 11a der Abtastsperre 11 genau in den Kanal 5a eintauchen kann. Diese Stellung wird dann erreicht, wenn die Noppen 11b, 11c, 11d, 11e in die radialen Nuten 7a, 8a, 9a, 10a der Basisscheiben eintauchen können.The bolt 5 has a tour pin channel 5a on its underside, as can be seen in FIG. 2. The latch 5 can only be withdrawn with the help of the control nut 2 when the cuboid 11a of the scanning lock 11 can be immersed exactly in the channel 5a. This position is reached when the knobs 11b, 11c, 11d, 11e can dip into the radial grooves 7a, 8a, 9a, 10a of the base disks.

Die Rastscheiben 13 - 16 weisen auf ihrer Rückseite n kegelartige Vertiefungen auf, die der Anzahl der Zähne entspricht. Die Basisscheiben 7 - 10 sind mit achsparallelen Bohrungen 7b, 8b, 9b, 10b versehen, in denen beidseitig zugespitzte zylindrische Kupplungsstifte 23 - 26 verschiebbar gelagert sind. Die Länge dieser Stifte ist so bemessen, daß sie in die Vertiefungen der Rastscheiben eintauchen, wenn die rechten Enden auf der ebenen Fläche der Umstellplatte aufliegen. Jede Basisscheibe 7 - 9 ist also in irgendeiner von n Positionen mit den Rastscheiben 13 - 16 und damit den Einstellknöpfen gekoppelt.The locking disks 13-16 have on their rear side n cone-like depressions, which corresponds to the number of teeth. The base disks 7-10 are provided with axially parallel bores 7b, 8b, 9b, 10b, in which cylindrical coupling pins 23-26 tapered on both sides are slidably mounted. The length of these pins is such that they dip into the recesses of the locking disks when the right ends rest on the flat surface of the changeover plate. Each base disk 7-9 is therefore coupled in any of n positions to the locking disks 13-16 and thus to the adjustment knobs.

Stellt man die gewählte Kombination ein, dann liegen die Nuten 7a, 8a, 9a, 10a vor den Noppen der Abtastsperre 11. Wenn man jetzt die Handhabe des Schlosses betätigt, fällt die Abtastsperre in die Nuten der Basisscheiben ein und der Sperrquader 11akann in den Tourstiftkanal 5a des Riegels eintauchen. Der Riegel läßt sich voll zurückziehen.
Wenn man die Tür schließt und den Schloßriegel 5 in die Türzarge einfährt, kann anschließend durch Drehung der Einstellknöpfe die Kombination verworfen werden. Das bedeutet , daß jede Basisscheibe 7 - 10 eine beliebige von n Positionen einnimmt, der Riegel also gesperrt ist.If you set the selected combination, the grooves 7a, 8a, 9a, 10a lie in front of the knobs of the scanning lock 11. If you now operate the handle of the lock, the scanning lock engages in the grooves of the base plates and the locking block 11a can enter the tour pin channel Immerse 5a of the latch. The latch can be pulled back fully.
If you close the door and retract the lock bolt 5 into the door frame, the combination can then be discarded by turning the adjusting knobs. This means that each base disc 7-10 takes any of n positions, so the bolt is locked.

B: Das UmstellsystemB: The changeover system

Wenn der Schloßriegel 5 zurückgezogen wird, bewegt die Steuernuß 2 über einen Steuerstift die Umstellplatte 6 in eine Umstellposition. In dieser Position steht jedem Stift 23 - 26 eine Kegelbohrung 6a, 6b, 6c, 6d gegenüber, so daß die Stifte aus den Rastscheiben 13 - 16 heraustreten, wenn die Einstellknöpfe betätigt werden. Diese Entkupplung bedeutet, daß jede Verdrehung der Einstellknöpfe bei offenem Schrank eine Neueinstellung der Kombination bewirkt. Wenn jetzt der Schrank verschlossen wird, geht die Umstellplatte 6 in die Normalstellung zurück und die Kupplungsstifte 23 - 26 werden in die Kupplungsposition zurückgeschoben.When the lock bolt 5 is withdrawn, the control nut 2 moves the changeover plate 6 into a changeover position via a control pin. In this position, each pin 23-26 is opposite a tapered bore 6a, 6b, 6c, 6d, so that the pins emerge from the locking disks 13-16 when the adjusting buttons are actuated. This uncoupling means that every turn of the adjustment buttons with the cabinet open causes a new adjustment of the combination. If the cabinet is now closed, the changeover plate 6 returns to the normal position and the coupling pins 23-26 are pushed back into the coupling position.

Bei geschlossenem Schrank bedeutet jede Verdrehung der Knöpfe ein Verwerfen der Kombination oder ihre Einstellung zum Öffnen des Schrankes.With the cabinet closed, any twisting of the knobs means discarding the combination or adjusting it to open the cabinet.

Bei offenem Schrank wird mit jeder Verstellung zwangsläufig eine neue Kombination eingestellt.With the cabinet open, a new combination is inevitably set with each adjustment.

C: ManipulationsschutzC: Tamper protection

Bei Kombinationsschlössern besteht grundsätzlich die Gefahr, daß Unbefugte versuchen, die Kombination abzutasten, indem sie mit Fingerspitzengefühl und Stethoskop die Handhabe und Knöpfe betätigen, um die Rastpunkte zu finden.With combination locks, there is always the risk that unauthorized persons try to sense the combination by operating the handle and buttons with fingertip sensitivity and a stethoscope to find the locking points.

Um dies sicher zu verhindern, wird der Stellschieber 3 mit Hilfe der Steuernuß 2 so bewegt, daß die am Schieber angebrachten Sperrstifte 3a, 3b, 3c, 3d sofort in die Verzahnung der Basisscheiben 7 - 10 einfallen und diese festhal ten. Die Einstellknöpfe lassen sich also nur verstellen, wenn die Handhabe nicht belastet wird.In order to prevent this, the adjusting slide 3 is moved with the help of the control nut 2 so that the locking pins 3a, 3b, 3c, 3d attached to the slide immediately fall into the toothing of the base disks 7-10 and hold them down. The adjusting knobs can be So only adjust if the handle is not loaded.

D: Das NotöffnungssystemD: The emergency opening system

Wenn Kombinationsschlösser außer in Banken in Hotels, Schwimmbädern, Schulen oder Gepäckaufbewahrungsstationen eingesetzt werden sollen, kommt ein großer, ungeübter Personenkreis damit in Berührung. Es wird daher häufiger vorkommen, daß das Einstellgeheimnis vergessen wird. Für diesen Fall ist ein Doppelbartschloß mit Notriegel 19 vorgesehen, dessen Dorn 19a den Abtasthebel 12 freigibt. Dieser unter Federkraft stehende Hebel weist Nasen 12a, 12b, 12c, 12d auf, die auf dem Zylindermantel der Basisscheiben 7 - 10 gleiten. Wenn man der Reihe nach die Knöpfe verstellt, fällt eine Nase nach der anderen in die Nuten 7a, 8a, 9a, 10a ein. Wenn danach die Handhabe betätigt wird, rastet auch die Abtastsperre 11 ein und gibt den Schloßriegel 5 frei.
Anschließend wird der Notriegel 19 zurückgeholt und der Schlüssel abgezogen. Dadurch gelangt der Abtasthebel erneut in die Sperrstellung, in der ein Einfallen in die Basisscheiben verhindert wird.If combination locks are to be used in banks, hotels, swimming pools, schools or luggage storage stations, a large, inexperienced group of people comes into contact with them. It will therefore happen more often that the secret of hiring is forgotten. In this case, a double-bit lock with emergency bolt 19 is provided, the spike 19a of which releases the scanning lever 12. This lever, which is under spring force, has lugs 12a, 12b, 12c, 12d which slide on the cylinder jacket of the base disks 7-10. If you turn the buttons one after the other, one nose after the other falls into the grooves 7a, 8a, 9a, 10a. If the handle is then actuated, the scanning lock 11 also engages and releases the lock bolt 5.
The emergency bolt 19 is then retrieved and the key removed. This causes the scanning lever to return to the locked position, preventing it from falling into the base plates.

Gewerbliche VerwertbarkeitCommercial usability

Die Herstellung des beschriebenen Schlosses kann entscheidend dadurch verbilligt werden, daß möglichst viele Teile aus einem schlagzähen, formstabilen Thermoplast gespritzt werden. Dies gilt für den Schloßkasten 1, den Riegel 5, die Basisscheiben 7 - 10, die Abtastsperre 11, die Rastscheiben 13 - 16 und die Einstellraste 18.
Das dargestellte, manipuliersichere Schloß kann vorteilhaft und problemlos in verschiedenen Arten von Wertschränken oder Wertfächern eingesetzt werden.The manufacture of the lock described can be made significantly cheaper by spraying as many parts as possible from an impact-resistant, dimensionally stable thermoplastic. This applies to the lock case 1, the bolt 5, the base disks 7-10, the scanning lock 11, the locking disks 13-16 and the adjustment catch 18th
The tamper-proof lock shown can be used advantageously and without problems in different types of valuables or value compartments.
