Definitions

  • the invention relates to a combination lock for containers such as suitcases, briefcases or the like. according to the preamble of claim 1, cf. also DE-A-3 030 440.
  • Combination locks with adjoining setting or number wheels are known.
  • Various options are known and in use for setting a new opening code or a new opening combination.
  • DE-B-28 28 057 shows a coding lever on the underside of the lock, for the operation of which the container or the case must be at least partially emptied or unpacked.
  • the coding lever protrudes into the interior of the container and can therefore easily be actuated or even accidentally damaged by the objects in the container.
  • a correspondingly large hole must be formed in the lining material possibly provided on the inner wall of the container, which hole must be protected against fraying.
  • a combination lock with adjusting wheels and coupling bushes is known, in which the latter can be pushed out of engagement with the adjusting wheels by means of a sliding mechanism, so that the opening combination of the combination lock can be changed.
  • the sliding mechanism includes an actuating part which is mounted coaxially with the coupling bushings and which has a peripheral section which projects outwards through an opening formed in a housing plate of the combination lock. If the opening combination of the combination lock is set on the setting wheels, the actuating part can be rotated in order to remove the engagement between the coupling bushes and the setting wheels in order to change the opening combination.
  • DE-B-28 16 073 shows a code adjustment device which is located in the area of the locking hole intended for the raid nose on the outside of the lock plate and in which one can only move the pull button further into a position in which a new one is pressed after it has been depressed Setting the opening combination or the opening code of the combination lock is made possible.
  • This type of code adjustment requires several additional components; the code adjustment device is also clearly visible and easily accessible in the event of an open hold-up, so that it can be operated by unauthorized persons easily and without any aids.
  • Combination locks are also known in which the code can be adjusted by moving the pull button either in the lock opening direction or in the opposite direction to the lock opening direction, e.g. from DE-A-30 30 440 and DE-B-29 46 091.
  • the invention has for its object the combination lock known from DE-A-30 30 440 for containers such as suitcases, briefcases or the like. to further develop such that with as few components as possible while avoiding the disadvantages mentioned above, the opening combination or the opening code can be adjusted in a simple manner from the outside of the container, an unconscious or unauthorized readjustment of the opening combination of the opening code being impossible or very difficult should be.
  • the "unlocking of the opening combination set on the setting wheels" is carried out by a coding element which is formed separately from the pull button and which is not actuated or adjusted if the pull button is merely shifted. Accordingly, an unintentional unlocking of the opening combination cannot be carried out by actuating the pull button. It is not possible to unlock the opening combination by playing around with the pull button.
  • a component, namely the coding element must be consciously actuated, which only for this purpose, namely unlocking of the opening combination set on the setting wheels, is provided.
  • Covering the coding element with the pull button ensures that the coding element is invisible when the combination lock is at rest; Accordingly, onlooking customers etc. are not encouraged to try out the function of the coding element.
  • the coordinated physical configuration of the actuating section of the coding element or of the pull button according to claim 2 offers the possibility of leaving the coding element largely “invisible” even when the pull button is actuated. Accordingly, actuation or adjustment of the coding element is only likely to be targeted by those who know the combination lock. In general, this should be the sales staff or a customer who has been instructed by the sales staff and who wants to purchase the container provided with the combination lock.
  • the coding element is covered by the pull button, it is ensured that the coding element can only be operated anyway if the opening combination previously set on the combination lock is set and the pull button can be moved at all. Before that, the coding element is completely inaccessible.
  • the storage of the coding element according to claim 4 enables a defined adjustment of the coding element in the free space predetermined by the lock plate recess. This exact mounting of the coding element ensures precise orientation and adjustment of the components to be moved by the coding element within the combination lock even when it is frequently adjusted.
  • the storage mentioned can be implemented by measures on components that are required for the combination lock anyway.
  • the design of the coding element with a rear wall arranged according to claim 6 releases those who have the opening combination of the combination lock wants to readjust from the need to hold the pull button during the readjustment.
  • the locking of the pull bolt connected to the pull button directly by the coding element thus considerably improves the ease of use of the combination lock.
  • the adjustment of the coding element can be implemented in a particularly simple manner by means of a bearing pin in a solution of the tooth engagement between the coupling bushes and the setting wheels.
  • the transmission of the pivoting movement of the coding element into an axial movement of the bearing pin can be realized particularly advantageously according to claim 8, since each time the pivoting element of the coding element is pivoted, the bearing pin is immediately and exactly moved into an axial position which corresponds to the corresponding pivoting position of the coding element.
  • the coding element according to claim 9 can advantageously be designed as a coding lever. Further advantageous refinements of the invention result from patent claims 10 and 11.
  • a combination lock shown in FIG. 1, in cooperation with a hold-up 9, is intended to prevent unauthorized opening of containers 35, in particular suitcases and briefcases.
  • the combination lock designed as a combination lock in the illustrated embodiment has three setting or numbering wheels 3.
  • the actuation of a pull button 2 is, as described in detail below, only possible if the setting wheels 3 previously in the predetermined opening combination have been asked.
  • the pull button 2 hides a lock plate recess 4.
  • a coding lever 1 is arranged, by means of which the predetermined opening combination can be changed.

Description

Die Erfindung bezieht sich auf ein Kombinationsschloß für Behältnisse, wie Koffer, Aktentaschen od.dgl. nach dem Oberbegriff des Patentanspruchs 1, vgl. auch die DE-A-3 030 440.The invention relates to a combination lock for containers such as suitcases, briefcases or the like. according to the preamble of claim 1, cf. also DE-A-3 030 440.

Kombinationsschlösser mit nebeneinander stehenden Einstell- bzw. Zahlenrädern sind bekannt. Zur Einstellung eines neuen Öffnungscodes bzw. einer neuen Öffnungskombination sind verschiedene Möglichkeiten bekannt und in Gebrauch.Combination locks with adjoining setting or number wheels are known. Various options are known and in use for setting a new opening code or a new opening combination.

Die DE-B-28 28 057 zeigt einen Codierhebel an der Schloßunterseite, zu dessen Bedienung das Behältnis bzw. der Koffer zumindest teilweise entleert oder ausgepackt werden muß. Der Codierhebel ragt in den Innenraum des Behältnisses vor und kann daher leicht unabsichtlich durch die im Behältnis befindlichen Gegenstände betätigt oder sogar beschädigt werden. Im evtl. vorgesehenen Futtermaterial auf der Innenwandung des Behältnisses muß ein entsprechend großes Loch ausgebildet sein, das gegen Ausfransen geschützt werden muß.DE-B-28 28 057 shows a coding lever on the underside of the lock, for the operation of which the container or the case must be at least partially emptied or unpacked. The coding lever protrudes into the interior of the container and can therefore easily be actuated or even accidentally damaged by the objects in the container. A correspondingly large hole must be formed in the lining material possibly provided on the inner wall of the container, which hole must be protected against fraying.

Ähnliches trifft für ein Kombinationsschloß mit innenliegendem Codier-Exzenterstift zu, wie es aus der DE-B-28 30 091 bekannt ist.The same applies to a combination lock with an internal coding eccentric pin, as is known from DE-B-28 30 091.

Aus der GB-A-20 79 836 ist ein Kombinationsschloß mit Einstellrädern und Kupplungsbuchsen bekannt, bei dem letztere mittels eines Schiebemechanismus außer Eingriff mit den Einstellrädern schiebbar sind, so daß die Öffnungskombination des Kombinationsschlosses verändert werden kann. Zum Schiebemechanismus gehört ein koaxial mit den Kupplungsbuchsen gelagertes Betätigungsteil, das einen Umfangsabschnitt aufweist, der durch eine in einer Gehäuseplatte des Kombinationsschlosses ausgebildete Öffnung nach draußen vorsteht. Wenn an den Einstellrädern die Öffnungskombination des Kombinationsschlosses eingestellt ist, kann das Betätigungsteil gedreht werden, um zwecks Veränderung der Öffnungskombination den Eingriff zwischen den Kupplungsbuchsen und den Einstellrädern aufzuheben.From GB-A-20 79 836 a combination lock with adjusting wheels and coupling bushes is known, in which the latter can be pushed out of engagement with the adjusting wheels by means of a sliding mechanism, so that the opening combination of the combination lock can be changed. The sliding mechanism includes an actuating part which is mounted coaxially with the coupling bushings and which has a peripheral section which projects outwards through an opening formed in a housing plate of the combination lock. If the opening combination of the combination lock is set on the setting wheels, the actuating part can be rotated in order to remove the engagement between the coupling bushes and the setting wheels in order to change the opening combination.

Die DE-B-28 16 073 zeigt eine Code-Verstelleinrichtung, die sich im Bereich des der Überfallennase zugedachten Verriegelungsloches auf der Schloßplatten-Außenseite befindet und bei der man nur nach deren Niederdrücken den Zugknopf weiter in eine Stellung bewegen kann, in der eine neue Einstellung der Öffnungskombination bzw. des Öffnungscodes des Kombinationsschlosses ermöglicht ist. Diese Art der Codeverstellung erfordert mehrere zusätzliche Bauteile; auch ist bei offener Überfalle die Code-Verstelleinrichtung gut sichtbar und leicht zugänglich, so daß sie von Unbefugten leicht und ohne Hilfsmittel betätigt werden kann.DE-B-28 16 073 shows a code adjustment device which is located in the area of the locking hole intended for the raid nose on the outside of the lock plate and in which one can only move the pull button further into a position in which a new one is pressed after it has been depressed Setting the opening combination or the opening code of the combination lock is made possible. This type of code adjustment requires several additional components; the code adjustment device is also clearly visible and easily accessible in the event of an open hold-up, so that it can be operated by unauthorized persons easily and without any aids.

Bekannt sind auch Kombinationsschlösser, bei denen die Codeverstellung durch Bewegen des Zugknopfes entweder in die Schloß-Öffnungrichtung oder entgegengesetzt zur Schloß-Öffnungsrichtung ermöglicht wird, z.B. aus der DE-A-30 30 440 und der DE-B-29 46 091.Combination locks are also known in which the code can be adjusted by moving the pull button either in the lock opening direction or in the opposite direction to the lock opening direction, e.g. from DE-A-30 30 440 and DE-B-29 46 091.

Bei den Kombinationsschlössern gemäß der GB-A-20 79 836, der DE-B-28 16 073, der DE-A-30 30 440 und der DE-B-29 46 091 hat sich die für die Neueinstellung der Öffnungskombination einfache Art der Codeverstellung mittels Betätigung des von außen ohne weiteres zugänglichen Betätigungsteils bzw. des Zugknopfes insoweit als Nachteil erwiesen, als erstens Fremde in den Kaufhäusern durch Betätigung der Kombinationsschlösser ausgestellter Koffer etc. leicht die Öffnungskombination verstellen können; selbst das Verkaufspersonal kennt diese neu eingestellte Öffnungskombination dann nicht. Zweitens kann auch ein späterer Koffereigentümer durch spielerisches Hantieren am Kombinationsschloß leicht die Öffnungskombination verstellen, ohne sich dessen bewußt zu sein. Zur Präsentation in Kaufhäusern werden deshalb an den Kombinationsschlössern häufig sog. Sicherungen angebracht, z.B. durch die Einstell- bzw. Zahlenräder gesteckte Plomben gemäß DE-B-29 38 000 oder die Bewegung des Zugknopfes in Codierrichtung blockierende Sperrplättchen gemäß DE-U-81 09 279; diese Sicherungsmaßnahmen erfordern jedoch den Einbau zusätzlicher Bauteile und bedeuten auch keinen sicheren Schutz, insbesondere für den späteren Koffereigentümer, der spielerisch am Kombinationsschloß herumhantiert.In the combination locks according to GB-A-20 79 836, DE-B-28 16 073, DE-A-30 30 440 and DE-B-29 46 091, the simple way of re-setting the opening combination has become Code adjustment by actuating the actuating part, which is easily accessible from the outside, or the pull button has proven to be a disadvantage in that firstly strangers in the department stores can easily adjust the opening combination by actuating the combination locks, etc. even the sales staff do not know this newly set opening combination. Secondly, even a later suitcase owner can easily adjust the opening combination by playing with the combination lock without being aware of it. For presentation in department stores, so-called fuses are therefore often attached to the combination locks, for example seals sealed by the setting or number wheels according to DE-B-29 38 000 or blocking plates blocking the movement of the pull button in the coding direction according to DE-U-81 09 279 ; However, these security measures require the installation of additional components and also do not mean secure protection, especially for the later case owner, who fiddles with the combination lock.

Der Erfindung liegt die Aufgabe zugrunde, das aus der DE-A-30 30 440 bekannte Kombinationsschloß für Behältnisse, wie Koffer, Aktentaschen od.dgl. derart weiterzubilden, daß bei ihm mit möglichst wenigen Bauteilen unter Vermeidung der vorstehend erwähnten Nachteile die Öffnungskombination bzw. der Öffnungscode vom Äußeren des Behältnisses her in einfacher Weise verstellt werden kann, wobei eine unbewußte bzw. unbefugte Neueinstellung der Öffnungskombination des Öffnungscodes unmöglich bzw. sehr erschwert sein soll.The invention has for its object the combination lock known from DE-A-30 30 440 for containers such as suitcases, briefcases or the like. to further develop such that with as few components as possible while avoiding the disadvantages mentioned above, the opening combination or the opening code can be adjusted in a simple manner from the outside of the container, an unconscious or unauthorized readjustment of the opening combination of the opening code being impossible or very difficult should be.

Diese Aufgabe wird erfindungsgemäß durch ein Kombinationsschloß gelöst, das neben den im Oberbegriff des Patentanspruchs 1 angegebenen Merkmalen auch die im kennzeichnenden Teil des Patentanspruchs aufgeführten Merkmale aufweist.This object is achieved according to the invention by a combination lock which, in addition to the features specified in the preamble of patent claim 1, also has the features listed in the characterizing part of the patent claim.

Erfindungsgemäß wird die Funktion "Entriegelung der an den Einstellrädern eingestellten Öffnungskombination" durch ein Codierelement vorgenommen, das separat vom Zugknopf ausgebildet ist und bei einer bloßen Verschiebung des Zugknopfes nicht betätigt oder verstellt wird. Demgemäß kann durch eine Betätigung des Zugknopfes eine unbeabsichtigte Entriegelung der Öffnungskombination nicht vorgenommen werden. Eine Entriegelung der Öffnungskombination durch Herumspielen am Zugknopf ist nicht möglich. Zu einer derartigen Entriegelung muß bewußt ein Bauteil, nämlich das Codierelement, betätigt werden, welches nur für diesen Zweck, nämlich Entriegelung der an den Einstellrädern eingestellten Öffnungskombination, vorgesehen ist.According to the invention, the "unlocking of the opening combination set on the setting wheels" is carried out by a coding element which is formed separately from the pull button and which is not actuated or adjusted if the pull button is merely shifted. Accordingly, an unintentional unlocking of the opening combination cannot be carried out by actuating the pull button. It is not possible to unlock the opening combination by playing around with the pull button. For unlocking of this type, a component, namely the coding element, must be consciously actuated, which only for this purpose, namely unlocking of the opening combination set on the setting wheels, is provided.

Durch die Abdeckung des Codierelements durch den Zugknopf ist sichergestellt, daß das Codierelement in Ruhestellung des Kombinationsschlosses unsichtbar ist; schaulustige Kunden etc. werden demgemäß nicht dazu angehalten, die Funktion des Codierelements auszuprobieren.Covering the coding element with the pull button ensures that the coding element is invisible when the combination lock is at rest; Accordingly, onlooking customers etc. are not encouraged to try out the function of the coding element.

Die aufeinander abgestimmte körperliche Ausgestaltung des Betätigungsabschnitts des Codierelements bzw. des Zugknopfes gemäß Patentanspruch 2 bietet die Möglichkeit, das Codierelement auch bei einer Betätigung des Zugknopfes weitgehend "unsichtbar" zu lassen. Eine Betätigung bzw. Verstellung des Codierelements ist demgemäß nur gezielt durch denjenigen wahrscheinlich, der das Kombinationsschloß kennt. Hierbei dürfte es sich im allgemeinen um das Verkaufspersonal oder um einen von dem Verkaufspersonal unterrichteten Kunden handeln, der das mit dem Kombinationsschloß versehen Behältnis käuflich erwerben will. Darüber hinaus ist bei der Abdeckung des Codierelements durch den Zugknopf gewährleistet, daß eine Betätigung des Codierelements sowieso erst dann erfolgen kann, wenn die am Kombinationsschloß vorher eingestellte Öffnungskombination eingestellt und der Zugknopf überhaupt verschiebbar ist. Vorher ist das Codierelement völlig unzugänglich.The coordinated physical configuration of the actuating section of the coding element or of the pull button according to claim 2 offers the possibility of leaving the coding element largely “invisible” even when the pull button is actuated. Accordingly, actuation or adjustment of the coding element is only likely to be targeted by those who know the combination lock. In general, this should be the sales staff or a customer who has been instructed by the sales staff and who wants to purchase the container provided with the combination lock. In addition, when the coding element is covered by the pull button, it is ensured that the coding element can only be operated anyway if the opening combination previously set on the combination lock is set and the pull button can be moved at all. Before that, the coding element is completely inaccessible.

Eine weitere Erhöhung der Sicherung des Codierelements gegen unbefugtes und unbewußtes Betätigen ergibt sich, wenn gemäß Patentanspruch 3 die Betätigung des Codierelements nicht mit der Hand möglich ist, sondern hierzu die Benutzung eines spitzen Gegenstandes erforderlich ist.A further increase in the security of the coding element against unauthorized and unconscious actuation results if, according to claim 3, the actuation of the coding element is not is possible by hand, but this requires the use of a pointed object.

Die Lagerung des Codierelements gemäß Patentanspruch 4 ermöglicht eine definierte Verstellung des Codierelements in dem durch die Schloßplattenaussparung vorgegebenen Freiraum. Diese exakte Lagerung des Codierelements sichert auch bei seiner oftmaligen Verstellung eine genaue Orientierung und Verstellung der durch das Codierelement innerhalb des Kombinationsschlosses zu bewegenden Bauteile. Darüber hinaus kann die genannte Lagerung durch Maßnahmen an Bauelementen verwirklicht werden, die ohnehin für das Kombinationsschloß erforderlich sind.The storage of the coding element according to claim 4 enables a defined adjustment of the coding element in the free space predetermined by the lock plate recess. This exact mounting of the coding element ensures precise orientation and adjustment of the components to be moved by the coding element within the combination lock even when it is frequently adjusted. In addition, the storage mentioned can be implemented by measures on components that are required for the combination lock anyway.

Mittels der Rastvorrichtung, wie sie im Patentanspruch 5 angegeben ist, ist eine exakte Einstellung der Blockierund der Freigabestellung des Codierelements möglich. Die durch das Codierelement zu bewegenden, innerhalb des Kombinationsschlosses vorgesehenen Bauteile sind demgemäß immer genau in die gewünschten Stellungen bringbar. Eine Beschädigung der Einzelteile des Kombinationsschlosses oder ein zu großer Kraftaufwand beim Einstellen einer neuen Öffnungskombination infolge ungenauer Ausrichtung der Bauteile des Kombinationsschlosses ist sicher vermieden.By means of the locking device, as specified in claim 5, an exact setting of the blocking and the release position of the coding element is possible. The components to be moved by the coding element and provided within the combination lock can accordingly always be brought into the desired positions. Damage to the individual parts of the combination lock or excessive effort when setting a new opening combination due to inaccurate alignment of the components of the combination lock is reliably avoided.

Die Ausgestaltung des Codierelements mit einer entsprechend Patentanspruch 6 angeordneten Rückwand entbindet denjenigen, der die Öffnungskombination des Kombinationsschlosses neu einstellen will, von der Notwendigkeit, während der Neueinstellung den Zugknopf festzuhalten. Die Verriegelung des mit dem Zugknopf verbundenen Zugriegels unmittelbar durch das Codierelement verbessert somit die Bedienungsfreundlichkeit des Kombinationsschlosses ganz erheblich.The design of the coding element with a rear wall arranged according to claim 6 releases those who have the opening combination of the combination lock wants to readjust from the need to hold the pull button during the readjustment. The locking of the pull bolt connected to the pull button directly by the coding element thus considerably improves the ease of use of the combination lock.

In besonders einfacher Weise läßt sich gemäß Patentanspruch 7 die Verstellung des Codierelements durch einen Lagerbolzen in eine Lösung des Zahneingriffs zwischen den Kupplungsbuchsen und den Einstellrädern umsetzen.According to claim 7, the adjustment of the coding element can be implemented in a particularly simple manner by means of a bearing pin in a solution of the tooth engagement between the coupling bushes and the setting wheels.

Die Übertragung der Verschwenkbewegung des Codierelements in eine Axialbewegung des Lagerbolzens ist besonders vorteilhaft gemäß Patentanspruch 8 zu verwirklichen, da hierbei bei jeder Verschwenkung des Codierelements unmittelbar und exakt der Lagerbolzen in eine Axialposition versetzt wird, die der entsprechenden Schwenkstellung des Codierelements entspricht. Vorteilhaft ist das Codierelement gemäß Patentanspruch 9 als Codierhebel gestaltbar. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Patentansprüchen 10 und 11.The transmission of the pivoting movement of the coding element into an axial movement of the bearing pin can be realized particularly advantageously according to claim 8, since each time the pivoting element of the coding element is pivoted, the bearing pin is immediately and exactly moved into an axial position which corresponds to the corresponding pivoting position of the coding element. The coding element according to claim 9 can advantageously be designed as a coding lever. Further advantageous refinements of the invention result from patent claims 10 and 11.

Im folgenden wird die Erfindung an Hand einer Ausführungsform unter Bezugnahme auf die Zeichnung näher erläutert.The invention is explained in more detail below using an embodiment with reference to the drawing.

Ein in Figur 1 dargestelltes Kombinationsschloß soll im Zusammenwirken mit einer Überfalle 9 ein unbefugtes Öffnen von Behältnissen 35, insbesondere Koffern und Aktentaschen, verhindern.A combination lock shown in FIG. 1, in cooperation with a hold-up 9, is intended to prevent unauthorized opening of containers 35, in particular suitcases and briefcases.

Das bei der dargestellten Ausführungsform als Zahlenschloß ausgebildete Kombinationsschloß weist drei Einstell- bzw. Zahlenräder 3 auf. Die Betätigung eines Zugknopfes 2 ist, wie im folgenden ausführlich beschrieben, nur dann möglich, wenn die Einstellräder 3 vorher in die vorgegebene Öffnungskombination gestellt worden sind. Der Zugknopf 2 verdeckt in seiner Ruhestellung eine Schloßplattenaussparung 4. In der Schloßplattenaussparung 4 ist ein Codierhebel 1 angeordnet, mittels dem die vorgegebene Öffnungskombination geändert werden kann. Der Codierhebel 1 ist zwischen seiner in Figur 2 und 6 dargestellten Blockierstellung und seiner in Figur 5 und Figur 7 dargestellten Freigabestellung verschwenkbar. An seinem vom Zugknopf 2 entfernten Ende weist der Codierhebel 1 einen Bolzenabschnitt 30 auf. Dieser Bolzenabschnitt 30 wird an einer Seite durch eine Ausnehmung 31, die in einem seitlichen Wandabschnitt des inneren Abdeckblechs 28 ausgebildet ist, und an der anderen Seite durch eine Ausnehmung 32, die zwischen einem hinteren Wandabschnitt des inneren Abdeckblechs 28 und einem u.a. die Einstellräder 3 aufnehmenden Gehäuse 18 ausgebildet ist, drehbar gelagert. Der Codierhebel 1 ist somit um seine durch den Bolzenabschnitt 30 bzw. durch die Ausnehmungen 31 und 32 definierte Drehachse schwenkbar.The combination lock designed as a combination lock in the illustrated embodiment has three setting or numbering wheels 3. The actuation of a pull button 2 is, as described in detail below, only possible if the setting wheels 3 previously in the predetermined opening combination have been asked. In its rest position, the pull button 2 hides a lock plate recess 4. In the lock plate recess 4, a coding lever 1 is arranged, by means of which the predetermined opening combination can be changed. The coding lever 1 can be pivoted between its blocking position shown in FIGS. 2 and 6 and its release position shown in FIGS. 5 and 7. At its end remote from the pull button 2, the coding lever 1 has a bolt section 30. This bolt section 30 is on one side by a recess 31 which is formed in a side wall section of the inner cover plate 28, and on the other side by a recess 32 which between a rear wall section of the inner cover plate 28 and one of the receiving wheels 3 Housing 18 is formed, rotatably mounted. The coding lever 1 can thus be pivoted about its axis of rotation defined by the bolt section 30 or by the recesses 31 and 32.

Für diese Verschwenkung ist der Codierhebel 1 mit einem Betätigungsabschnitt 29 ausgerüstet. Dieser Betätigungsabschnitt 29 ist unmittelbar unter dem Zugknopf 2 angeordnet und in Ruhestellung des Zugknopfes 2 von diesem abgedeckt. Der Verstellweg des Zugknopfes 2 und die Abmessung des Betätigungsabschnitts 29 des Codierhebels 1 sind so aufeinander abgestimmt, daß die den Zugknopf 2 betätigenden Gliedmaße, d.h. der Daumen oder Finger einer Hand, normalerweise den Betätigungsabschnitt 29 des Codierhebels 1 abdeckt, wenn der Zugknopf 2 aus seiner Ruhe- in seine Öffnungsstellung verstellt wird.For this pivoting, the coding lever 1 is equipped with an actuating section 29. This actuating section 29 is arranged directly below the pull button 2 and covered by the pull button 2 in the rest position. The adjustment of the pull button 2 and the dimension of the actuating section 29 of the coding lever 1 are coordinated so that the limb actuating the pull button 2, ie the thumb or finger of a hand, normally covers the actuating section 29 of the coding lever 1 when the Pull button 2 is adjusted from its rest to its open position.

Zur Betätigung des Codierhebels 1, die nur dann möglich ist, wenn der Daumen bzw. Finger den normalerweise zur Verstellung des Zugknopfes 2 berührten Teilabschnitt des Zugknopfes 2 freigibt und diesen anders festhält, ist der Betätigungsabschnitt 29 auf seiner nach außen, d.h. in Richtung auf den Zugknopf 2 orientierten Seite, mit einer Vertiefung 26 versehen, in die ein spitzer Gegenstand, z.B. eine Kugelschreiberspitze od.dgl., eingeführt wird; durch diesen Gegenstand ist die zur Verschwenkung des Codierhebels 1 erforderliche Kraft auf den letzteren übertragbar.To actuate the coding lever 1, which is only possible when the thumb or finger releases the section of the pull button 2 that is normally touched for the adjustment of the pull button 2 and holds it differently, the operating section 29 is on its outside, i.e. towards the pull button 2 side, provided with a recess 26 into which a pointed object, e.g. a ballpoint pen tip or the like is inserted; this object enables the force required to pivot the coding lever 1 to be transferred to the latter.

Der Codierhebel 1 ist mit einem etwa von seinem Bolzenabschnitt 30 nach außen sich erstreckenden Vorsprung 33 versehen, an dessem freien Ende eine Rastausnehmung 14 ausgebildet ist. Diese Rastausnehmung 14 wirkt mit Rastbuckeln 13 zusammen, die so auf der Innenwandung des inneren Abdeckblechs 28 positioniert und ausgestaltet sind, daß der Codierhebel 1 in seiner Blockier- und in seiner Freigabestellung eingerastet werden kann.The coding lever 1 is provided with a projection 33 which extends approximately outward from its bolt section 30 and at its free end a locking recess 14 is formed. This locking recess 14 interacts with locking bosses 13, which are positioned and designed on the inner wall of the inner cover plate 28 so that the coding lever 1 can be locked in its blocking and in its release position.

Der Betätigungsabschnitt 29 des Codierhebels 1 geht in einen Abschnitt über, in dem auf der in Axialrichtung des Bolzenabschnitts 30 dem Vorsprung 33 abgewandten Seite des Codierhebels 1 eine Ausnehmung 34 ausgebildet ist. Ein Wandungsbereich dieser Ausnehmung 34 ist, wie am besten aus den Figuren 5 und 6 hervorgeht, als Verstellschräge 6 ausgebildet.The actuating section 29 of the coding lever 1 merges into a section in which a recess 34 is formed on the side of the coding lever 1 facing away from the projection 33 in the axial direction of the bolt section 30. A wall area of this recess 34 is, as best shown in the figures 5 and 6 emerges, designed as adjustment bevel 6.

Darüber hinaus weist der Codierhebel 1 eine Rückwand 15 auf, die bei Verschwenkung des Codierhebels 1 aus seiner Blockierin seine Freigabestellung eine Kante 16 eines mittels dem Zugknopf 2 in seine Freigabestellung gebrachten Zugriegels 25 hintergreift; der Zugriegel 25 verbleibt somit bei in Freigabestellung verschwenktem Codierhebel 1 auch dann in seiner eigenen Freigabestellung, wenn der Zugknopf 2 entlastet wird.In addition, the coding lever 1 has a rear wall 15 which, when the coding lever 1 is pivoted out of its blocking position, engages behind an edge 16 of a pull bolt 25 brought into its release position by means of the pull button 2; The drawbar 25 thus remains in its own release position when the coding lever 1 is pivoted into the release position even when the pull button 2 is released.

In der die Verstellschräge 6 aufweisenden Ausnehmung 34 ist das eine Ende 37 eines Lagerbolzens 5 des Kombinationsschlosses aufgenommen, der nahe diesem einen Ende 37 im Gehäuse 18 verschiebbar gelagert ist. An den im Gehäuse 18 gelagerten Abschnitt des Lagerbolzens 5 schließt sich in der sich vom Codierhebel 1 entfernenden Richtung ein radial vorstehender Lagerbolzenbund 7 an, der einstückig mit dem oder in Axialrichtung fixiert am Lagerbolzen 5 ausgebildet bzw. angebracht ist. Auf der codierhebelfernen Seite des Lagerbolzenbundes 7 sind auf dem Lagerbolzen 5 bei der vorliegenden Ausführungsform drei Kupplungsbuchsen 8 gelagert. Jede Kupplungsbuchse 8 ist mit jeweils einem zu ihr koaxial angeordneten Einstellrad 3 versehen. Auf dem Außenumfang jeder Kupplungsbuchse 8 ist eine äußere Verzahnung 11, auf dem Innenumfang jedes Einstellrads 3 eine innere Verzahnung 12 ausgebildet. Die Kupplungsbuchsen 8 sind in Axialrichtung in bezug auf die in Axialrichtung fest im Gehäuse 18 gelagerten Einstellräder 3 bewegbar; durch diese Axialverschiebung ist der Zahneingriff zwischen der äußeren Verzahnung 11 der Kupplungsbuchsen 8 und der inneren Verzahnung 12 der Einstellräder 3 lösbar. Die codierhebelnahe Kupplungsbuchse 8 liegt mit ihrer codierhebelnahen Stirnseite gegen die codierhebelferne Stirnseite des Lagerbolzenbunds 7 an. Die codierhebelferne Stirnseite der codierhebelfernen Kupplungsbuchse 8 wird von einem Schenkel 10 einer Feder 36 beaufschlagt, die die Kupplungsbuchsen 8 und über den Lagerbolzenbund 7 den Lagerbolzen 5 in Richtung auf den Grund der im Codierhebel 1 ausgebildeten Ausnehmung 34 vorspannt. Das codierhebelferne Ende 20 des Lagerbolzens 5 ist axial verschieblich in einer sog., in Figur 3a dargestellten Clipslagerung 19 gelagert.The one end 37 of a bearing pin 5 of the combination lock is accommodated in the recess 34 which has the adjustment bevel 6 and is slidably mounted near this one end 37 in the housing 18. A radially projecting bearing pin collar 7 adjoins the section of the bearing pin 5 which is mounted in the housing 18 in the direction away from the coding lever 1 and which is formed or attached to the bearing pin 5 in one piece with or fixed in the axial direction. On the side of the bearing pin collar 7 remote from the coding lever, three coupling bushes 8 are mounted on the bearing pin 5 in the present embodiment. Each coupling bushing 8 is provided with an adjusting wheel 3 arranged coaxially with it. An outer toothing 11 is formed on the outer circumference of each coupling bushing 8, and an inner toothing 12 is formed on the inner circumference of each adjusting wheel 3. The coupling bushes 8 are movable in the axial direction with respect to the setting wheels 3 which are fixedly mounted in the axial direction in the housing 18; through this axial displacement the tooth engagement between the outer toothing 11 of the coupling bushes 8 and the inner toothing 12 of the setting wheels 3 releasable. The coding bushing near the coupling sleeve 8 rests with its coding lever end face against the coding lever end face of the bearing pin collar 7. The end of the coupling sleeve 8 remote from the coding lever is acted upon by a leg 10 of a spring 36, which prestresses the coupling bushes 8 and, via the bearing pin collar 7, the bearing pin 5 in the direction of the bottom of the recess 34 formed in the coding lever 1. The end 20 of the bearing bolt 5 remote from the coding lever is axially displaceably mounted in a so-called clip bearing 19 shown in FIG. 3a.

Die den Lagerbolzen 5 mittels ihres Schenkels 10 in Richtung auf den Codierhebel 1 zu vorspannende Feder 36 hat einen weiteren Schenkel 17, mittels dem sie den Zugriegel 25 und damit den mit diesem in einer mechanischen Verbindung stehenden Zugknopf 2 in Richtung auf eine Eingriffstellung zwischen dem Zugriegel 25 und der Überfalle 9 vorspannt.The spring 36 to be preloaded by means of its leg 10 in the direction of the coding lever 1 has a further leg 17 by means of which it pulls the drawbar 25 and thus the pull button 2 which is in mechanical connection therewith in the direction of an engagement position between the drawbar 25 and the raid 9 biased.

Jede Kupplungsbuchse 8 ist, wie aus den Figuren 8 und 9 hervorgeht, mit einem geraden, abgeflachten Umfangsabschnitt 38 ausgestaltet. An den entsprechenden Stellen ist für jede Kupplungsbuchse 8 im Gehäuse 18 jeweils ein federndes Segment 21 angeformt. Jedes dieser federnden Segmente 21 wird durch eine Blattfeder 23 in Richtung auf den Umfang der Kupplungsbuchse 8 zu vorgespannt, so daß das federnde Segment 21 mit einer freien, geraden Kante gegen diesen Umfang anliegt.As can be seen from FIGS. 8 and 9, each coupling bush 8 is designed with a straight, flattened peripheral section 38. At the corresponding points, a resilient segment 21 is formed in each case for each coupling bushing 8 in the housing 18. Each of these resilient segments 21 is biased by a leaf spring 23 in the direction of the circumference of the coupling bush 8, so that the resilient segment 21st with a free, straight edge against this circumference.

Das federnde Segment 21 ist durch Drehen der Kupplungsbuchse 8 aus einer Blockierstellung, in der die gerade Kante des federnden Segments 21 gegen einen runden Abschnitt des Umfangs der Kupplungsbuchse 8 anliegt, in eine Freigabestellung verstellbar, in der die gerade Kante des federnden Segments 21 gegen den geraden Umfangsabschnitt 38 der Kupplungsbuchse 8 anliegt. In seiner in den Figuren 9 und 9a dargestellten Blockierstellung ragt das federnde Segment 21 in die Bewegungsbahn von am Zugriegel 25 ausgebildeten Vorsprüngen 22. Der Zugriegel 25 kann in dieser Stellung der federnden Segmente 21 nicht in seiner Längsrichtung bewegt werden, d.h., eine Bewegung des Zugriegels aus dessen Schließ- in dessen Öffnungs-Stellung ist nicht möglich.The resilient segment 21 is adjustable by rotating the coupling bushing 8 from a blocking position in which the straight edge of the resilient segment 21 abuts against a round section of the circumference of the coupling bushing 8 in a release position in which the straight edge of the resilient segment 21 against the straight circumferential portion 38 of the coupling bush 8 abuts. In its blocking position shown in FIGS. 9 and 9a, the resilient segment 21 protrudes into the movement path of projections 22 formed on the drawbar 25. The drawbar 25 cannot be moved in its longitudinal direction in this position of the resilient segments 21, ie a movement of the drawbar from its closed to its open position is not possible.

Auf dem Außenumfang der Einstellräder 3 sind in vorgegebenem Umfangsabstand Rastkerben 27 ausgebildet. Die Rastkerben 27 wirken mit einem Federarm 24 der Blattfeder 23 zusammen. Wenn der Federarm 24 in eine Rastkerbe 27 eingerastet ist, ist am Einstellrad 3 eine bestimmte Ziffer eingestellt. Zum Weiterdrehen des Einstellrads muß eine Drehkraft aufgebracht werden, durch die der Federarm 24 aus der Rastkerbe 27 herausgedrückt wird. Jede Rastkerbe 27 entspricht einer bestimmten Ziffer.Notches 27 are formed on the outer circumference of the adjusting wheels 3 at a predetermined circumferential distance. The notches 27 interact with a spring arm 24 of the leaf spring 23. When the spring arm 24 is locked in a notch 27, a certain number is set on the adjusting wheel 3. To turn the setting wheel further, a rotational force must be applied by which the spring arm 24 is pressed out of the notch 27. Each notch 27 corresponds to a certain number.

Im folgenden wird der Vorgang einer Neueinstellung des vorstehend beschriebenen Kombinationsschlosses erläutert.The process of readjusting the combination lock described above is explained below.

Zunächst wird an den Einstellrädern 3 die bisher geltende Öffnungskombination, hier eine Zahlenkombination, eingestellt. Wenn an allen drei Einstellräder 3 die korrekte Ziffer eingestellt ist, liegen infolge der Vorspannung durch die Blattfeder 23 alle federnden Segmente 21 mit der oben erwähnten freien Kante gegen den geraden Umfangsabschnitt 38 der jeweiligen Kupplungsbuchse 8 an, wie in Figur 8 dargestellt. Die Bewegungsbahn, die bei einer Längsverschiebung des Zugriegels 25 von den an ihm ausgebildeten Vorsprüngen 22 durchlaufen wird, ist frei, wie in Figur 8a für ein federndes Segment 21 dargestellt. Durch ein Verschieben des Zugknopfes 2 kann nun der Zugriegel 25 gegen die Kraft des Schenkels 17 der Feder 36 aus dem in Figur 2 dargestellten Schließeingriff mit der Überfalle 9 herausgezogen werden, wie in Figur 7 gezeigt ist. In dieser Stellung des Zugknopfes ist der Betätigungsabschnitt 29 des Codierhebels 1 nicht mehr länger vom Zugknopf 2 abgedeckt. Nunmehr wird ein spitzer Gegenstand, nämlich eine Kugelschreiberspitze, ein kleiner Schraubenzieher od.dgl., in die im Betätigungsabschnitt 29 vorgesehene Vertiefung 26 eingeführt. Der Codierhebel 1 wird dann unter Zurhilfenahme des spitzen Gegenstands aus der in Figur 6 dargestellten Blockierstellung in seine in Figur 5 dargestellte Freigabestellung verschwenkt. Bei dieser Schwenkbewegung des Codierhebels 1 wird das in der Ausnehmung 34 aufgenommene Ende 37 des Lagerbolzens 5 durch die Verstellschräge 6 gegen die Kraft des Schenkels 10 der Feder 36 vom Codierhebel 1 weggedrückt. Mit dem Lagerbolzen 5 werden der Lagerbolzenbund 7 und damit die Kupplungsbuchsen 8 in dieselbe Richtung, d.h. nach links in den Figuren 2 und 7, gedrückt. Hierdurch geraten die inneren, auf den Einstellrädern 3 ausgbildeten Verzahnungen 12 und die äußeren, auf den Kupplungsbuchsen 8 ausgebildeten Verzahnungen 11 außer Eingriff. Die Einstellräder 3 können nunmehr in bezug auf die Kupplungsbuchsen 8 verdreht werden. Eine Zurückstellung des Zugriegels 25 in dessen Schließstellung wird durch die beim Verschwenken des Codierhebels 1 hergestellte Anlage zwischen der Kante 16 des Zugriegels 25 und der Rückwand 15 des Codierhebels 1 verhindert, wie aus Figur 4 hervorgeht. Ein weiteres Blockieren oder Festhalten des Zugknopfes 2 ist somit nach der Verschwenkung des Codierhebels 1 nicht mehr erforderlich.First of all, the previously used opening combination, here a number combination, is set on the adjusting wheels 3. If the correct number is set on all three setting wheels 3, all resilient segments 21 with the free edge mentioned above bear against the straight circumferential section 38 of the respective coupling bushing 8, as shown in FIG. The movement path which is traversed by the projections 22 formed thereon when the pull bolt 25 is displaced longitudinally is free, as shown in FIG. 8a for a resilient segment 21. By moving the pull button 2, the drawbar 25 can now be pulled out against the force of the leg 17 of the spring 36 from the locking engagement with the hold-up 9 shown in FIG. 2, as shown in FIG. In this position of the pull button, the actuating section 29 of the coding lever 1 is no longer covered by the pull button 2. Now a pointed object, namely a ballpoint pen tip, a small screwdriver or the like, is inserted into the recess 26 provided in the actuating section 29. The coding lever 1 is then pivoted with the aid of the pointed object from the blocking position shown in FIG. 6 into its release position shown in FIG. 5. During this pivoting movement of the coding lever 1, the end 37 of the bearing pin 5 received in the recess 34 is pressed away from the coding lever 1 by the adjustment bevel 6 against the force of the leg 10 of the spring 36. With the bearing pin 5 Bearing pin collar 7 and thus the coupling bushes 8 pressed in the same direction, ie to the left in Figures 2 and 7. As a result, the inner teeth 12 formed on the adjusting wheels 3 and the outer teeth 11 formed on the coupling bushes 8 disengage. The setting wheels 3 can now be rotated with respect to the coupling bushes 8. A return of the pull bolt 25 in its closed position is prevented by the system produced when the coding lever 1 is pivoted between the edge 16 of the pull bolt 25 and the rear wall 15 of the coding lever 1, as can be seen from FIG. A further blocking or holding of the pull button 2 is therefore no longer necessary after pivoting the coding lever 1.

Sobald an den Einstellrädern 3 die erwünschte neue Öffnungskombination eingestellt worden ist, wird der Codierhebel 1 gegen die Kraft der durch den entsprechenden Rastbuckel 13 und die Rastausnehmung 14 gebildeten Rastverbindung aus seiner Freigabestellung zurück in seine Blockierstellung verschwenkt, wo die an seinem Vorsprung 33 vorgesehene Rastausnehmung 14 mit dem entsprechend positionierten, weiteren Rastbuckel 13 in Eingriff gerät.As soon as the desired new opening combination has been set on the setting wheels 3, the coding lever 1 is pivoted against the force of the locking connection formed by the corresponding locking boss 13 and the locking recess 14 from its release position back into its blocking position, where the locking recess 14 provided on its projection 33 engages with the correspondingly positioned, further locking boss 13.

Während dieser Verschwenkung des Codierhebels 1 wandert das codierhebelseitige Ende 37 des Lagerbolzens 5 infolge der durch den Schenkel 10 der Feder 36 ausgeübten Vorspannkraft auf der Verstellschräge 6 in Richtung auf den Codierhebel 1 zu. Der Zahneingriff zwischen den Kupplungsbuchsen 8 und den Einstellrädern 3 wird wieder hergestellt. Die neue Öffnungskombination ist eingestellt.During this pivoting of the coding lever 1, the coding lever-side end 37 of the bearing pin 5 migrates towards the coding lever 1 due to the pretensioning force exerted by the leg 10 of the spring 36 on the adjustment bevel 6. The Tooth engagement between the coupling bushes 8 and the adjusting wheels 3 is restored. The new opening combination has been set.

Gleichzeitig mit der Verstellung des Codierhebels 1 und des Lagerbolzens 5 wandert auch der Zugriegel 25 infolge der vom Schenkel 17 der Feder 36 auf ihn ausgeübten Vorspannkraft zurück in seine Schließstellung. Der Betätigungsabschnitt 29 des Codierhebels 1 wird wieder vom Zugknopf 2 verdeckt.Simultaneously with the adjustment of the coding lever 1 and the bearing pin 5, the drawbar 25 also moves back into its closed position as a result of the pretensioning force exerted on it by the leg 17 of the spring 36. The actuating section 29 of the coding lever 1 is again covered by the pull button 2.

Nun können durch Verdrehen der Einstellräder 3 die federnden Segmente 21 in ihre die Bewegungsbahn der Vorsprünge 22 des Zugriegels 25 versperrende Blockierstellung gebracht werden, wonach das Kombinationsschloß sicher abgesperrt ist.Now, by rotating the setting wheels 3, the resilient segments 21 can be brought into their blocking position blocking the movement path of the projections 22 of the latch 25, after which the combination lock is securely locked.

Das Kombinationsschloß läßt sich jetzt nur noch mit der neu eingestellten Öffnungskombination öffnen.The combination lock can now only be opened with the newly set opening combination.

Eine irrtümliche oder unerwünschte Verstellung der Öffnungskombination bzw. des Öffnungscodes wird zum einen durch die Abdeckung des Codierhebels 1 durch den Zugknopf bzw. durch die diesen bedienenden Gliedmaße und zum anderen durch das Erfordernis eines spitzen Gegenstands zur Verschwenkung des Codierhebels 1 erschwert.An erroneous or undesirable adjustment of the opening combination or the opening code is made more difficult on the one hand by the coding lever 1 being covered by the pull button or by the limbs serving it, and on the other hand by the requirement of a pointed object for pivoting the coding lever 1.
