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 sein, und einer Handhabe, die einen von den Einsstellknöpfen gesteuerten Riegel antreibt.The invention relates to a combination lock with four adjusting knobs in the lock case be arranged in a rectangle, and a handle, one of the adjustment buttons controlled bolt drives.

Stand der TechnikState of the art

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

Die französische Patentschrift 2.032.214, die als nächstliegender Stand der Technik anzusehen ist, behandelt ein Kombinationsschloß mit vier im Quadrat angeordneten Einstellknöpfen. Diese Einstellknöpfe sind mit vier gezahnten Basisscheiben gekuppelt, die jeweils eine radiale Nut aufweisen. Über den Basisscheiben ist ein Stellschieber angeordnet, die über den Umfangskreisen der Basisscheiben vier Nasen tragen. Im Sperrzustand blockiert der Stellschieber den Schloßriegel. Wenn alle vier Basisscheiben auf die richtige Kombination eingestellt sind, kann der Stellschieber in die Öffnungsposition verschoben werden, in der die genannten Nasen in die Nuten der Basisscheiben eintauchen.French patent specification 2,032,214, which is to be regarded as the closest prior art, deals with a combination lock with four Square adjustment knobs. These knobs have four toothed base plates coupled, each having a radial groove. Is over the base plates a slide valve arranged, four lugs above the circumferential circles of the base plates carry. The locking slide blocks the lock bolt in the locked state. If all four base plates are adjusted to the correct combination, the slide valve can be inserted into the Opening position can be moved, in which the tabs mentioned in the grooves of the base plates immerse yourself.

Bei einer anderen Ausführungsform trägt das Sperrelement vier Dorne, die in Kerben der Basisscheiben eintauchen können. Hierbei ist das den Riegel blockierende Sperrelement drehbar ausgebildet. Ein Sperrstift liegt dabei in einer Aussparung des Riegels oder er wird aus dieser herausgeschwenkt.In another embodiment, the locking element carries four mandrels, which in the notches Can immerse the base plates. Here is the locking element blocking the bolt rotatable. A locking pin lies in a recess in the bolt or he is swung out of this.

Bei entriegeltem Schloß bewirkt eine Verdrehung der Einstellknopfe eine Neueinstellung der Kombination. Die Basisscheiben werden dabei vom Sperrelement bzw. vom Stellschieber festgehalten. Eine Kugelrasteinrichtung zwischen den Einstellknöpfen und den Basisscheiben ermöglicht ein Drehen der Einstellknöpfe relativ zu den Basisscheiben, damit eine neue Kombination erhalten wird. When the lock is unlocked, it causes twisting the adjustment knob readjust the combination. The base plates are thereby from the locking element or held by the adjusting slide. A ball lock device between the adjustment knobs and the base discs allows the adjustment knobs to be turned relative to the Base disks to get a new combination becomes.

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, each with 26 setting positions, so that 26 3 = 42875 combinations are possible. In this embodiment, there are very small angular steps, so that high manufacturing precision is required.

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 le 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 preferably consists of a dimensionally stable Thermoplastic is injected. There are guide tubes in the four corners 1a, 1b, 1c, 1d formed for the fastening screws. The lock case floor le carries four injected bearing sleeves 1f, 1g, 1h, 1i for storage of the rotating parts. Another bearing mandrel 1k is between the bearing sleeves arranged.

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.The largest part of the lock housing is from the combination mechanism filled out. In the right part there is a double-bit change lock with an emergency bolt that 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.Immediately on the lock case base 1e is a control nut 2 with a Square recess, a slide 3 and a changeover bar 4. Above the Control nut 2, the lock bolt 5 is mounted. A changeover plate 6 is on the mandrel 1k pivoted. It has a series of oval openings on the u.a. encompass the bearing sleeves 1f, 1g, 1h, 1i. To this Sleeves are slid on four base plates 7, 8, 9, 10. Between Base discs is a cross-shaped scanning lock 11, also a scanning lever 12th

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 washers 13, 14, 15, 16 with square inner opening are on the one hand guided in the base plates 7-10 and on the other hand in the castle ceiling 17 stored. A resilient adjustment catch 18 ensures that the locking washers can always be adjusted by full steps.

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 on its underside a tour pin channel 5a, as is results from Fig. 2. The latch 5 can then only be withdrawn with the help of the control nut 2 when the cuboid 11a of the scanning lock 11 is exactly in can immerse the channel 5a. This position is reached when the Nubs 11b, 11c, 11d, 11e in the radial grooves 7a, 8a, 9a, 10a of the base disks can immerse.

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 n cone-like depressions on their rear side that corresponds to the number of teeth. The base discs 7-10 are provided with axially parallel bores 7b, 8b, 9b, 10b, in which Tapered cylindrical coupling pins 23 - 26 slidably mounted on both sides are. The length of these pins is such that they fit into the recesses Immerse the locking washers when the right ends are level Rest the surface of the changeover plate. Each base disc 7 - 9 is in any one from n positions with the locking washers 13 - 16 and thus the adjusting knobs coupled.

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 over a control pin the changeover plate 6 in a changeover position. In this position each pin 23 - 26 faces a tapered bore 6a, 6b, 6c, 6d, so that the pins come out of the locking disks 13-16 when the adjusting knobs be operated. This uncoupling means that every twist the adjustment buttons when the cabinet is open to readjust the combination causes. If the cabinet is now closed, the changeover plate will go 6 back 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.When the cabinet is closed, any twisting of the knobs means discarding the combination or its setting for opening the cabinet.

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

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 palpate the combination by being sensitive and the stethoscope operate the handle and buttons to close the locking points Find.

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 from happening, the adjusting slide 3 is made with the help of the control nut 2 moved so that the locking pins 3a, 3b, 3c attached to the slide 3d immediately fall into the toothing of the base plates 7-10 and this hold on. The adjustment knobs can only be adjusted if the handle is not charged.

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 gelangtder 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.

Claims (3)

  1. Combination lock having four setting knobs, which are arranged in a rectangle in the lock case (1), and having a handle, which drives a bolt (5) controlled by the setting knobs,
    wherein the lock case base (1e) has four bearing bushes (1e, 1f, 1g, 1i), on which are supported four base discs (7, 8, 9, 10) provided with a number (n) of teeth, wherein each base disc in its lateral surface has a radial slot (7a, 8a, 9a, 10a),
    wherein a cross-shaped detecting interlock (11) is pivotally supported between the base discs (7 - 10) and has four bumps (11b, 11c, 11d, 11e), which fit into the slots of the base discs, and a locking square (11a), which engages into the bolt,
    wherein detent discs (13, 14, 15, 16) provided with a number (n) of teeth and with a square socket are supported on the base discs (7 - 10), each detent disc (13 - 16) having a number (n) of tapered bores,
    wherein the setting knobs provided with square shafts and a number (n) of numbers or figures engage into the detent discs,
    wherein the number (n) of teeth of the base discs, the number (n) of teeth and the number (n) of conical bores of the detent discs and the number (n) of numbers or letters of the setting knobs are identical,
    wherein each base disc (7 - 10) has a paraxial bore, wherein each bore has a coupling pin (23 - 26) provided with tapered ends,
    wherein said pins may engage into tapered bores (6a, 6b, 6c, 6d) of a resetting plate (6) and into one of the conical bores of the detent discs (13 - 16),
    wherein the pivotally supported resetting plate (6) is operated by a follower (2) of the lock bolt (5),
    wherein the resetting plate (6) during extension of the lock bolt (5) is swivelled in such a way that it presses up the coupling pins (23 - 26) and couples the base discs (7 - 10) to the detent discs (13 - 16) with the result that, after closure of the cabinet, the combination may be concealed by rotating the setting knobs whereas, in the retracted state of the lock bolt (5), a tapered bore of the resetting plate (6) lies opposite each coupling pin (23 - 26) with the result that the base discs (7 - 10) and the detent discs (13 - 16) are uncoupled so that each rotation of the setting knobs effects the setting of a new combination.
  2. Combination lock according to claim 1, characterized in that the follower (2) of the lock bolt (5) drives a setting slide (3), the locking pins (3a, 3b, 3c, 3d) of which engage into the teeth of the base discs (7, 8, 9, 10), so that the setting knobs are blocked when the handle is under load.
  3. Combination lock according to claim 1, characterized in that a double bit lock is provided with an emergency bolt 19, the mandrel (19a) of which releases a spring-loaded detecting lever (12), the lugs (12a, 12b, 12c, 12d) of which upon adjustment of the setting knobs drop successively into the slots (7a, 8a, 9a, 10a) of the base discs (7, 8, 9, 10) and hold them fast in their opening position so that subsequently, upon operation of the handle, the bumps (11b, 11c, 11d, 11e) of the detecting interlock may engage and the lock bolt (5) is retractable.
