Abstract

The bar lock for mounting in one or two rectangular perforations (32, 34), preferably in the tilting space of sheet-metal cabinet doors, has a lock (16) with a follower (64) which carries a pinion (62) and is held rotatably in a follower and rod bearing (60) and which is rotatable by means of an actuating device, such as a handle, pivoting lever, socket wrench or the like, guided outwards through the door leaf (12). It also has at least one rod (18) which extends parallel to the door edge, if appropriate in the tilting space (10), possesses a toothing or perforation (66) for the engagement of the pinion (62) in the region of the lock (16) and is mounted displaceably in this region and at at least one point outside the lock (16) in the door leaf (12). Locking devices are attached to the door frame and to the rod (18) and come into engagement with one another during the displacement of the rod (18). According to the invention, the rod (or rods) (18) and the follower and rod bearing (60) guiding these rods (18) in the region of the lock (16) are respectively made symmetrical or double-symmetrical in such a way that, without the removal of the pinion (62), the bar lock can be used both for doors opening to the right and for those opening to the left, with any selectable opening direction of rotation of the lock-actuating device, simply by reversing or interchanging the rod or rods (18) and/or reversing the lock (16). <IMAGE>

Description

Die Erfindung betrifft einen Stangeverschluß für Blechschranktüren gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a rod lock for sheet metal cabinet doors according to the preamble of claim 1.

Ein derartiger Stangeverschluß findet sich in der DE-OS 34 07 700. Dieser Stangenverschluß hat gegenüber anderen Konstruktionen, wie sie bespielsweise aus dem deutschen Gebrauchsmuster 85 05 588 oder auch aus der europäischen Patentschrift 00 54 225 bekannt sind, den Vorteil, daß mit bandförmigen Schubstangen gearbeitet wird, so daß die Gesamtbreite des Stangenverschlusses erheblich schmaler bleibt als bei den früheren Konstruktionen und daher ggf. auch in dem relativ engen Verkantungsraum vom Blechschranktüren untergebracht werden kann, wobei dies Unterbringungsart den besonderen Vorteil aufweist, daß zum einen das innere lichte Volumen eines Schaltschrankes für andere Bauteile, insbesondere Schalteinrichtungen, voll zur Verfügung steht, andererseits ansonsten toter Raum ausgenutzt wird, und schließlich, was von besonderer Bedeutung ist, sich der Stangenverschluß außerhalb des abzudichtenden Bereiches des Schrankes befindet, so daß bei dem Stangenverschluß der eingangs genannten Art irgendwelche Dichtungseinrichtungen entbehrlich sind.Such a rod lock can be found in DE-OS 34 07 700. This rod lock has the advantage over other constructions, such as are known, for example, from German utility model 85 05 588 or from European patent 00 54 225, that with band-shaped push rods is worked so that the overall width of the rod lock remains considerably narrower than in the previous designs and can therefore possibly also be accommodated in the relatively narrow canting space of the metal cabinet doors, this type of accommodation having the particular advantage that, on the one hand, the inside clear volume of a control cabinet for other components, in particular switching devices, is fully available, otherwise dead space is used, and finally, which is of particular importance, the rod lock is located outside the area to be sealed in the cabinet, so that the entrance to the rod lock s mentioned type any sealing devices are unnecessary.

Nachteilig bei dem bekannten Stangenverschluß ist jedoch, daß zwar durch besondere Ausgestaltung des Mittelteils (Fig. 8 der Entgegenhaltung) oder der Enden der Schubstange (Fig. 7) (Anordnung von Verzahnungen an den Schmalseiten der Schubstangen) diese Schubstangen sowohl für links wie auch für rechts angeschlagene Schaltschranktüren verwendbar sind, jedoch können die Stangen-zumindest nicht bei durchgehenden Stangen-nicht auf einfache Weise bei bereits vormontiertem Schloß gewechselt werden, vielmehr muß unter Entfernung einer Abdeckkappe 38 (Fig. 3) und eines Sicherungsringes (in Ringnut 32) vorher das Ritzel in umständlicher Weise aus dem Schloß demontiert werden. Erst dann können die Stangen herausgenommen, in der gewünschten Weise gewechselt, wieder eingesetzt und das Ritzel erneut montiert werden. Dies gilt zwar insbesondere dann, wenn eine durchgehende Schubstange verwendet wird, die nicht in den Führungskanal eines vormontierten Schloßkastens eingeschoben werden kann, aber auch bei nicht durchgebender Stange, bei der die Schubstange am Ende mit der Verzahnung versehen ist und daher an sich von oben oder von unten in den Schloßkasten einschiebbar ist, kann dieses Einschieben in Folge noch anderer Führungseinrichtungen nur nach Demontage anderer Bauteile möglich sein. Falls die an der Stange angeordneten Verriegelungseinrichtungen durch Einschnitte in der Stange gebildet werden, wird es zudem schwierig, die Stangen sowohl links wie auch rechts zu verwenden, bzw. die Betätitungseinrichtung zu ändern, weil die dann notwendigen beidseitigen Einschnitte eine zu starke Schwächung der Stange bewirken können. Ein weiterer Nachteil ist die Tatsache, daß beim Stand der Technik das Ritzel nur einseitig gelagert ist, was die Belastung des Lagermaterials und des Ritzelmaterials erhöht und u. U. die Verwendung einfacher Kunststoffmaterialien für diese Bauteile ausschließt.A disadvantage of the known rod lock, however, is that by special design of the central part (Fig. 8 of the document) or the ends of the push rod (Fig. 7) (arrangement of teeth on the narrow sides of the push rods) these push rods for both left and for cabinet doors hinged on the right can be used, but the rods - at least not with continuous rods - cannot be easily replaced with the lock already preassembled, rather the cover cap 38 (Fig. 3) and a retaining ring (in ring groove 32) must be removed beforehand Pinion can be disassembled from the lock in a cumbersome manner. Only then can the rods be removed, changed in the desired manner, reinserted and the pinion reinstalled. This is particularly true if a continuous push rod is used that cannot be inserted into the guide channel of a pre-assembled lock case, but also for a rod that does not pass through, in which the push rod is provided with the toothing at the end and therefore per se from above or can be inserted from below into the lock case, this insertion can only be possible as a result of other guiding devices only after dismantling other components. If the locking devices arranged on the bar are formed by incisions in the bar, it also becomes difficult to use the bars both on the left and on the right, or to change the actuating device, because the cuts on both sides then necessary cause the bar to be weakened too much can. Another disadvantage is the fact that in the prior art the pinion is only supported on one side, which increases the load on the bearing material and the pinion material and u. U. excludes the use of simple plastic materials for these components.

Aufgabe der Erfindung ist es, einen bekannten Stangenverschluß derart weiterzubilden, daß er weiterehin rechts und links verwendet werden kann und auch die Schließ- und Öffnungsrichtung des Schlosses frei bestimmbar bleibt, gleichzeitig aber eine nachträgliche Änderung ohne umständliche Demontagearbeiten ermöglicht, wobei gleichzeitig die Konstruktion des Antriebs der Schubstangen derart abgewandelt werden sollte, daß dessen einzelne Bauteile auf Wunsch auch aus einfachen Kunststoffmateralien hergestellt werden können.The object of the invention is to develop a known rod lock such that it can continue to be used on the right and left and the closing and opening direction of the lock remains freely definable, but at the same time allows subsequent changes without cumbersome dismantling work, while at the same time the construction of the drive the push rods should be modified in such a way that its individual components can also be made from simple plastic materials on request.

Das weiteren sollte der Antrieb bezüglich der Flachstange möglichst axial angreifen, um unerwünschte, die Reibung erhöhende Verkantungen auszuschließen. Beim Stand der Technik sind derartige Verkantungserschienungen nicht immer zu verhindern, weil dort der Antrieb einseitig an der Flachstange angreift.Furthermore, the drive should engage axially with respect to the flat rod as far as possible in order to exclude undesired canting which increases the friction. In the prior art, such tilting splinting cannot always be prevented because there the drive acts on one side on the flat rod.

Aus der DE-A-20 33 042 ist an sich bekannt, bei einem Getriebe für einen Treibstangenbeschlag das Getriebegehäuse aus zwei identischen Teilen zu bilden und das Antriebsritzel in diesem Getriebegehäuse zu lagern. Das Getriebegehäuse bildet auch Führungsschlitze für eine Treibstange. Zwei Treibstangen können nicht angetrieben werden, und das Gehäuse steht auch in keinem Zusammenhang mit einem Schlüsselfang oder Schlüsselschild.From DE-A-20 33 042 it is known per se to form the gear housing from two identical parts in a gear for a connecting rod fitting and to store the drive pinion in this gear housing. The gear housing also forms guide slots for a drive rod. Two connecting rods cannot be driven, and the housing has no connection with a key catch or key tag.

Gelöst wird die oben genannten Aufgabe dadurch, daß das Antrieb/Ritzel- und Stangenlager des Stangenverschlußschlosses ein vom Schlüsselfang oder Schlüsselschild gebildetes Basisteil, das das eine Ende der Schloßnuß oder des Ritzels lagert, und ein auf das Basisteil aufsetzbares und mit diesem mittels Schrauben o. dgl. verbindbares Kappenteil aufweist, das das andere Ende der Schloßnuß oder des Ritzels lagert und das (ggf. zusammen mit dem Basisteil) Führungsschlitze für die Stange(n) bildet. Diese Kombination von Merkmalen ermöglicht die Lösung der oben gestellten Aufgabe. Insbesondere ist es möglich, durch Abnehmen des Kappenteils ohne auch noch zusätzliches Entfernen einer Ritzelarreitierung, wie Sicherungsring, das Ritzel zusammen mit der einen oder den zwei Schubstangen aus dem Stangenverschlußschloß herauszunehmen und beispielsweise durch Umsetzen der Schubstangen oder durch Austausch einer Schubstange den Stangenverschluß an eine neue Aufgabenstellung anzupassen. Die Konstruktion erlaubt auch die Verwendung von Kunststoffen für die Einzelteile des Antriebs, was die Herstellung vereinfacht und die Geräuschentwiklung beim Betätigen des Verschlusses verringert. Die Konstruktion erlaubt auch ein mittiges Angreifen des Ritzels an den Schubstangen und vermeidet auf diese Weise ein Verkanten und damit möglicherweise erhöhte Reibung und entsprechend erhöhter Kraftbedarf. Die Konstruktion ist auch insofern von Vorteil, als sie sich leicht an ein Verschlußsystem anpassen läßt, das das Auswechseln verschiedener Handgriffe, Verschlußeinrichtungen und ähnliches ermöglichen soll. Der erfindungsgemäße Stangenverschluß ist daher vielseitiger anwendbar als es beim Stand der Technik der Fall ist.The above-mentioned object is achieved in that the drive / pinion and rod bearing of the rod lock lock is a base part formed by the key catch or key plate, which supports one end of the lock nut or pinion, and a mountable on the base part and with this by means of screws o. Like. Connectable cap part, which supports the other end of the lock nut or pinion and which (possibly together with the base part) forms guide slots for the rod (s). This combination of features enables the above task to be solved. In particular, it is possible to remove the pinion together with the one or two push rods from the rod lock lock by removing the cap part without also additionally removing a pinion locking device, such as a locking ring, and for example by moving the push rods or by exchanging a push rod the rod lock to a new one Adapt task. The construction also allows the use of plastics for the individual parts of the drive, which simplifies production and reduces the noise development when the lock is actuated. The design also allows the pinion to be gripped centrally on the push rods and in this way prevents tilting and thus possibly increased friction and ent speaking increased power requirements. The construction is also advantageous in that it can be easily adapted to a locking system which is intended to enable the replacement of various handles, locking devices and the like. The rod closure according to the invention is therefore more versatile than is the case with the prior art.

Trotz der vielseitigen Anwendbarkeit besteht der Verschluß nur aus wenigen Einzelteilen, was neben der Verbilligung der Herstellung und einer Vereinfachung der Montage und Umstellung auch einer Vereinfachung der Lagerhaltung zugute kommt.Despite the versatility, the closure consists of only a few individual parts, which in addition to the cheaper manufacture and simplification of assembly and conversion also benefits a simplification of storage.

Es ist günstig, wenn das Kappenteil im Kappenboden eine zentrale Öffnung für die Nußlagerung und je eine ober- und unterhalb der zentralen Öffnung angeordnete, in das Kappeninnere ragende Augen mit je einer eingesenkten Bohrung zur Aufnahme einer Befestigungsschraube aufweist. Auf diese Weise läßt sich das Kappenteil zum Zwecke der Auswechslung von beispielsweise der Stangen, aber auch zum Auswechseln der Art der Betätigungseinrichtung leicht demontieren. Besteht das Antrieb/-Ritzel- und Stangenlager aus einem Basisteil und einem Kappenteil von im wesentlichen identischem Aufbau, ergeben sich weitere Herstellungsvereinfachungen und damit Kosteneinsparungen. Montagevereinfachungen ergeben sich, wenn durch in weiteren Unteransprüchen geschilderte Maßnahmen Basisteil und Kappenteil gegenseitige Führungen aufweisen. Durch über das Basisteil und über die Stirnfläche hinausragende Vorsprünge läßt sich zudem eine Blattfeder anordnen, die sich an den Nußumfang anlegt und diesen gegen ungewollte Verdrehung sichert, insbesondere dann, wenn der Nußumfang im Abstand von 90° Abflachungen zur Aufnahme der Blattfeder in den Ruhestellungen des Verschlusses aufweist.It is favorable if the cap part has a central opening for the nut bearing in the cap base and one eye each, which is arranged above and below the central opening and projects into the cap interior, each with a countersunk bore for receiving a fastening screw. In this way, the cap part can be easily dismantled for the purpose of changing, for example, the rods, but also for changing the type of actuating device. If the drive / pinion and rod bearing consists of a base part and a cap part of an essentially identical construction, there are further manufacturing simplifications and thus cost savings. Assembly simplifications result if the base part and cap part have mutual guides as a result of the measures described in further subclaims. By protruding beyond the base part and beyond the end face, a leaf spring can also be arranged, which rests against the circumference of the nut and secures it against unwanted rotation, especially when the circumference of the nut is at 90 ° flats to accommodate the leaf spring in the rest positions of the Has closure.

Durch die besondere Konstruktion des erfindungsgemäßen Schlosses kann die Basis sowohl Teil eines Schwenkhebelverschlusses sein, wie auch Teil eines Handhebelverschlusses, eines Doppelbarverschlusses oder auch eines noch andersartigen Verschlusses. Dabei ist ggf. nur ein einziges Teil des gesamten Verschlusses auszutauschen, was wiederum zu erheblichen Kosteneinsparungen führt, sowohl hinsichtlich der Herstellung wie auch hinsichtlich der Lagerhaltung und Montage.Due to the special construction of the lock according to the invention, the base can be part of a swivel lever lock as well as part of a hand lever lock, a double bar lock or even a different type of lock. In this case, only a single part of the entire closure may have to be replaced, which in turn leads to considerable cost savings, both in terms of production and in terms of storage and assembly.

Gemäß einer noch anderen Weiterbildung der Erfindung, die insbesondere der verkantungsfreien Übertragung der Antriebskräfte vom Ritzel auf die Stangen dient, ist die Flachprofil aufweisende Stange des Stangenverschlusses axialsymmetrisch bezüglich der Längsachse und bezüglich einer Querachse, die den perforierten bzw. gezahnten Bereich der Stange halbiert.According to yet another development of the invention, which is used in particular for the tilt-free transmission of the drive forces from the pinion to the rods, the flat profile rod of the rod closure is axially symmetrical with respect to the longitudinal axis and with respect to a transverse axis which bisects the perforated or toothed region of the rod.

Fig. 1 zeigt in einer Ansicht auf den Verkantungsraum 10 einer Blechschrankttür 12 einen in diesem Raum angeordneten Stangenverschluß 14, bestehend aus einem Schloß 16, von dem eine im Verkantungsraum 10 verlaufende Stange 18 ausgeht, die zum einen innerhalb des Schlosses 16, zum anderen aber auch am Türblatt 12 in einem Stangenlager 20 verschieblich gelagert ist. Die Blechstranktür 12 ist über Scharnierbänder 22, siehe Fig. 2, am Schrankkorpus 24 angelenkt, die ihrerseits den anderen Verkantungsraum 11 ausnutzen, der von einem zwischen der äußeren Verkantungsraum 11 ausnutzen, der von einem zwischen der äußeren Abkantung 26 und einem innen auf das Türblatt aufgeschweißten, eine Dichtung 28 aufnehmenden Profilblech 30 gebildet ist. Ublicherweise ist in Blechschränkten, die derartige Verkantungsräume 10, 11 besitzen, in dem Verkantungsraum für den Verschluß ein rechteckiger Durchbruch 32 bzw. 34 angeordnet, bei geplanter Anwendung von versenkbaren Schwenkhebelverschlüssen sind es zwei symmetrisch zur horizontalen Türmitte 36 angeordnete Rechteckdurchbrüche 32 und 34.Fig. 1 shows a view of the canting space 10 of a sheet metal cabinet door 12 a rod lock 14 arranged in this space, consisting of a lock 16, from which a rod 18 extending in the canting space 10 extends, which on the one hand inside the lock 16, but on the other is also slidably mounted on the door leaf 12 in a rod bearing 20. The sheet metal door 12 is hinged to the cabinet body 24 via hinge straps 22, see FIG. 2, which in turn exploit the other canting space 11, which is used by one between the outer canting space 11, that of one between the outer canting 26 and one on the inside of the door leaf welded, a seal 28 receiving profile sheet 30 is formed. Usually, a rectangular opening 32 or 34 is arranged in the tilting space for the lock in sheet metal cabinets which have such tilting spaces 10, 11; when planned use of retractable pivot lever locks, there are two rectangular openings 32 and 34 arranged symmetrically to the horizontal door center 36.

Wie aus Fig. 3, einer axialen Schnittansicht entlang der Linie B-B der Fig. 1, zu erkennen ist, ist am Schrankkorpus 24 ein hakenartiger Vorsprung 38 angeschraubt, in den beim Schließen das Stangenverschlusses ein von der Verschlußstange 18 getragener Doppelrollzapfen 40 eindringt und so eine Verriegelung 42 bildet.As can be seen from FIG. 3, an axial sectional view along the line BB of FIG. 1, a hook-like projection 38 is screwed onto the cabinet body 24, into which a double roller pin 40 carried by the locking rod 18 penetrates when the rod lock closes, and so one Lock 42 forms.

Eine Möglichkeit zur Stangenführung ist im Schnitt D-D wiedergegeben, welche Stangenführung 20 im Eckraum des Abkantkanals 10 angeordnet und so gestaltet ist, daß die Flachbandstange 18 in die Führung eingeschoben werden kann. Die Führung 20 kann allerdings auch auf der anderen Seite der Stange 18, also außerhalb des manchmal für Schweißarbeiten schlecht zugänglichen Eckbereichs des Türblatts angebracht sein.One possibility for the rod guide is shown in section D-D, which rod guide 20 is arranged in the corner space of the folding channel 10 and is designed so that the flat ribbon rod 18 can be inserted into the guide. However, the guide 20 can also be attached to the other side of the rod 18, that is to say outside of the corner region of the door leaf which is sometimes difficult to access for welding work.

Aus Fig. 3 geht weiterhin hervor, daß das Schloß 32 ein Schloßnuß-, Ritzel- und Stangenlager 60 umfaßt, das eine ein Ritzel 62 tragende Schloßnuß 64 drehbar hält. Die Schloßnuß 64 ist hier mit Hilfe einer durch das Türblatt 12 nach außen geführten Betätigungseinrichtung, wie Griff, Schwenkhebel (siehe Fig. 4) Steckschlüssel (Fig. 3) oder dgl. verdrehbar, wobei das Rizel, das in entsprechende Perforierungen oder Zahnungen 66 der Stange 18 eingreift, diese auf und ab schiebt.3 further shows that the lock 32 comprises a lock nut, pinion and rod bearing 60 which rotatably holds a lock nut 64 carrying a pinion 62. The lock nut 64 can be rotated here with the aid of an actuating device, such as a handle, swivel lever (see FIG. 4), socket wrench (FIG. 3) or the like, which is guided through the door leaf 12, the rizel, which is in corresponding perforations or serrations 66 Rod 18 engages, pushes it up and down.

Das Schloßnuß-, Ritzel- und Stangenlager 60 besteht gemäß der Darstellung von Fig. 3 aus einem Basisteil 68, in das das eine Ende der Shloßnuß 64 lagert, und einem auf das Basisteil 68 aufsetzbaren Kappenteil 70, das mittels Schrauben 72 am Basisteil festgelegt ist und das andere Ende der Nuß lagert. Wie aus der Schnittdarstellung A-A ker Fig. 2 hervorgeht, bildet das Schloßnuß-, Ritzel- und Stangenlager 60 auch Führungsschlitze 74 und 76 zum wahlweisen Einlegen der Stange 18 entweder in der dargestellten Weise, bei der die Schließrichtung dem Uhrzeigersinn folgt, oder im Kanal 74, bei der eine umgekehrt Schließrichtung für Betätigungseinrichtung sich ergibt.3, the lock nut, pinion and rod bearing 60 consists of a base part 68, in which one end of the lock nut 64 is mounted, and a cap part 70 which can be placed on the base part 68 and is fixed to the base part by means of screws 72 and the other end of the nut rests. As can be seen from the sectional view AA ker Fig. 2, the lock nut, pinion and rod bearing 60 also forms guide slots 74 and 76 for the optional insertion of the rod 18 either in the manner shown, in which the closing direction follows the clockwise direction, or in the channel 74 , in which there is an opposite closing direction for the actuating device.

Um dieses Wenden der durchgehenden Stange 18 und auf diese Weise eine Änderung der Drehrichtung hinsichtlich der Betätigungseinrichtung zu ermöglichen, kann die Stange 18, siehe auch die Fig. 8 und 9, zweifach axialsymmetrisch ausgeführt sein, nämlich einmal um die Longitudinalachse 78, zum anderen um die Querachse 80. Die Symmetrie erfaßt hier auch ausgestanzte Anschlagnasen 84, die sich an die Außenfläche des Schlosses 16 legen und dadurch den Bewegungsweg der Stange begrenzen, wie auch die Verkröpfungen 82, die den Freiraum für die Anordnung des Ritzels 62 ergeben. Ebenso betroffen von der Symmetrie sind hier die Bohrungen 86, 87, die zur Aufnahme der bereits beschriebenen Doppelrollzapfen 40 vorgesehen sind. Der Bewegungsweg der Stange kann aber auch dadurch begrenzt werden, daß die Stangenperforation 66 der Stange 18 jeweils nur n Zähne 67 (wobei gemäß Fig. 36 n=5 ist) umfaßt, von denen zwei sich gegenüberligende Zähne eine abgeflachte Anschlagfläche 69 aufweisen. Die Abflachung der Anschlagfläche kann vorzugsweise an die Stangenebene 71 anschlagen, wenn der in das letzte Perforationsloch eingespurte benachbarte Zahn gerade senkrecht zur Stangenebene steht.In order to enable this turning of the continuous rod 18 and in this way a change in the direction of rotation with respect to the actuating device, the rod 18, see also FIGS. 8 and 9, can be configured twice axially symmetrically, namely once around the longitudinal axis 78 and around the transverse axis 80. The symmetry here also includes punched-out stop lugs 84, which lie on the outer surface of the lock 16 and thereby limit the path of movement of the rod, as well as the crankings 82, which give the space for the arrangement of the pinion 62. Likewise affected by the symmetry here are the bores 86, 87, which are provided for receiving the double roller pin 40 already described. The path of movement of the rod can also be limited in that the rod perforation 66 of the rod 18 comprises only n teeth 67 (where n = 5 according to FIG. 36), of which two opposing teeth have a flattened stop surface 69. The flattening of the abutment surface can preferably strike the rod plane 71 when the adjacent tooth inserted into the last perforation hole is just perpendicular to the rod plane.

In Fig. 11 sind die beiden beschreibenen Anordnungen der Stange 18 dargstellt, die auch Doppelrollzapfen 42 erkennen lassen.In Fig. 11, the two described arrangements of the rod 18 are shown, which also show double roller pin 42.

Das Basisteil 68 ist in Fig. 12 in einer Draufsicht, einer Axialschnittansicht, einer Ansicht von hinten und in einer Querschnittansicht dargestellt. Das hier dargestellte Basisteil dient, wie erkennbar, für einen Doppelbartverschluß und deckt gleichzeitig das zweite rechtekige Loch 34 ab, indem es mit einer einstückigen Abdeckplatte 88, die in einen Haken 90 übergeht, sich hinter den unteren Rand des Durchbruchs 34 legt, während das obere Ende des Basisteils 68 durch die rechteckige Öffnung 32 hindurchreicht und mit einem Rand 92 abdeckt. Zur Lagerung der Schloßnuß 64 dient eine kreisförmige Einsenkung 94, während eine weitere Einsenkung 96 verkleinerten Durchmessers zur Aufnahme des Kopfes 100 eines Doppelbartschlüsseleinsatzes 98 dient, der mit einem weiteren Teil dieses Kopfes, der auch eine Umfangsnut 104 zur Aufnahme einer eventuellen O-Ring-Dichtung besitzt, sowie mit einem Fußteil 102 in dem Ritzel 64, siehe Fig. 17, drehstarr gelagert ist und mit Hilfe einer hier nicht dargestellten Schraube, die in ein Sackgewindeloch 106 eingeschraubt werden kann, und mit Hilfe einer Vierkantsteckverbindung 108 eine drehstarre Verbindung zwischen diesen beiden Bauteilen 64 und 98 ermöglicht. Die Bauteile könnten auch einstükkig sein, jedoch ist der Vorteil dieser Kombination aus zwei Teilen der, daß der Einsatz 98, der hier für einen Doppelbartschlüssel vorgesehen ist, in einfacher Weise ausgetauscht werden kann gegen einen Einsatz für eine andere Schlüsselart, so daß das Ritzel 64 für ganz verschiedene Schlüsselarten benutzt werden kann. So kann beispielsweise anstelle des Einsatzes 98 gemäß Fig. 16 das Schwenklager eines Schwenkhebelverschlusses, wie er in Fig. 4 dargestellt ist, verwendet werden, siehe Fig. 18. Dieses Schwenklager 110 mit dem zugehörigen Ritzel 64 (Fig. 15) kann dann in eine Basisteil 168 eingesetzt werden, das in Fig. 17 näher dargestellt ist. Dieses Basisteil 168 weiste wiederum die Einsenkung 94 und eine Lagerfläche 96 auf, besitzt aber außerdem eine Kugelfläche 112, um einen Schwenkhebel 114 lagern zu können.The base part 68 is in a plan view in FIG. 12, an axial sectional view, a rear view and shown in a cross-sectional view. The base part shown here serves, as can be seen, for a double-bit lock and at the same time covers the second right-hand hole 34 by laying behind the lower edge of the opening 34 with an integral cover plate 88, which merges into a hook 90, while the upper End of the base part 68 extends through the rectangular opening 32 and covers with an edge 92. A circular depression 94 is used to support the lock nut 64, while a further depression 96 of reduced diameter serves to receive the head 100 of a double-bit key insert 98, which with another part of this head also has a circumferential groove 104 for receiving a possible O-ring seal has, as well as with a foot part 102 in the pinion 64, see Fig. 17, rotatably mounted and with the help of a screw, not shown here, which can be screwed into a blind threaded hole 106, and with the aid of a square connector 108, a torsionally rigid connection between these two Components 64 and 98 allows. The components could also be in one piece, but the advantage of this combination of two parts is that the insert 98, which is provided here for a double-bit key, can be exchanged in a simple manner for an insert for another type of key, so that the pinion 64 can be used for very different types of keys. For example, instead of the insert 98 according to FIG. 16, the pivot bearing of a pivot lever lock, as shown in FIG. 4, can be used, see FIG. 18. This pivot bearing 110 with the associated pinion 64 (FIG. 15) can then be in a Base part 168 can be used, which is shown in more detail in Fig. 17. This base part 168 again had the depression 94 and a bearing surface 96, but also has a spherical surface 112 in order to be able to mount a pivot lever 114.

Auch das Basisteil kann so ausgestaltet werden, daß es für den Einsatz unterschiedlicher Schlüsselfänge geeignet ist, siehe die in Fig. 17 bzw. 28 und 29 dargestellte Ausführungsform mit der Bezugsziffer 168 bzw. 468 sowie das Bauteil 368 und 668 in Fig. 20 bzw. 31, auf welche Bauteile später eingegangen wird.The base part can also be designed such that it is suitable for the use of different key catches, see the embodiment shown in FIGS. 17 or 28 and 29 with the reference number 168 or 468 and the component 368 and 668 in FIG. 20 or 31, which components will be discussed later.

Das Basisteil 68 in seinen verschiedenen Ausgestaltungen wird üblicherweise aus Kunststoff gespritzt sein und in diesem Falle z.B. eingespritzte Sackbohrungen 116 bzw. Durchgangsbohrungen 18 aufweisen, if die die Befestigungsschrauben 72 sich ihr eigenes Gewinde schaffend einschneiden. Spritzt man die Teile aus Metall, wird man entsprechende Gewindesack- bzw. -Durchgangslöcher vorsehen.The base part 68 in its various configurations will usually be injection molded from plastic and in this case e.g. have injected blind holes 116 or through holes 18 if the fastening screws 72 cut their own thread. If you spray the parts out of metal, you will provide appropriate threaded sack or through holes.

Der Kunststoff ermöglicht eine im wesentlichen abnutzungsfreie und wenig Reibungskräfte erfordernde Gleitlagerung.The plastic enables an essentially wear-free sliding bearing that requires little friction.

Es gibt Schränke, die nur einen rechteckigen Durchbruch 32 aufweisen. In diesem Falle braucht ein zweiter Durchbruch 34 nicht abgedeckt zu werden. Es genügt dann ein vereinfachtes Basisteil, das die Abdeckplatte 88 nicht aufweist. Es kann aber auch so ausgestaltet sein, siehe Fig. 19, daß eine Abdeckplatte 188 nachträglich in eine entsprechende Einsenkung 120 eingesteckt werden kann. Das in Fig. 19 dargestellte Basisteil 268, das hinsichtlich der Nußlagerung dem Basisteil 68 der Fig. 12 entspricht, weist als Besonderheit insgesamt vier Vorsprünge 122 auf, die zwei Federbügel 124 halten. Die Federbügel schleifen auf dem Umfang der Nuß 264, die mit Abflachungen 128 versehen ist, in die sich die Feder 124, wie rechts in Fig. 19 dargestellt, einlegt und so eine Arretierung in vier um 90° verschobene Stellungen bewirkt.There are cabinets that have only a rectangular opening 32. In this case, a second opening 34 need not be covered. A simplified base part that does not have the cover plate 88 is then sufficient. However, it can also be designed, see FIG. 19, that a cover plate 188 can subsequently be inserted into a corresponding depression 120. The base part 268 shown in FIG. 19, which corresponds to the base part 68 of FIG. 12 with regard to the nut bearing, has as a special feature a total of four projections 122 which hold two spring clips 124. The spring clips rub on the circumference of the nut 264, which is provided with flats 128, into which the spring 124, as shown on the right in FIG. 19, is inserted and thus causes a locking in four positions shifted by 90 °.

Auf das in den Fig. 3, 19, 20, 14 in verschiedenen Ausführungsformen beschreibene Basisteil 68, 268, 368 oder 568 kann nach Einführen in den oder die Durchbrüche 32, 34 im Türblatt 12 und Einsetzen der gewünschten Art von Schloßnuß 64, 264 sowie nach entsprechender Anbringung zugehöriger Betätigungsstangen 18 das Kappenteil 70 oder 170 aufgesetzt werden, das in Fig. 13 in einer ersten Ausführungsform näher zu erkennen ist. Das Kappenteil 70 weist im Kappenboden 130 eine zentrale Öffnung 132 für die Lagerung der Nuß und je ein ober- und unterhalb der zentralen Öffnung 132 angeordnetes und in das Kappeninnere ragendes Auge 134 mit einer eingesenkten Bohrung 136 zur Aufnahme der Befestigungsschraube 72 auf. Vom Kappenboden 130 gehen zwei zu den Führungsschlitzen 138 parallele längere Seitenwände 140 aus, sowie daz senkrechte kürzere Seitenwände 142, welche letztere an das Auge 134 anschließen und von deren Endkanten jsweils eine in das Kappeninnere ragende Stütz-und Führungswand 143 führt, die jeweils zur längeren Seitenwand 140 parallel im Abstand angeordnet ist und mit dieser jeweils einen Teil des Führungsschlitzes 138 bildet. Dieses Kappenteil 70 paßt z.B. auf die Basisteile 68, 168, 268 gemäß Fig. 3, 4, 17, 19, wobei die Wand 143 bis zur inneren Stirnfläche z.B. das Basisteils 68 reicht. Der von den Befestigungsschrauben 72 ausgeübte Preßdruck wird allerdings im wesentlichen von den Stirnflächen der Seitenwände 142, 140 auf die Randbereiche des Türblattdurchbruches 32 (gemäß Fig. 1) übertragen und dient dazu, den Verschluß im Türblatt sicher festzuhalten.3, 19, 20, 14 in various embodiments described base part 68, 268, 368 or 568 can after insertion into the or openings 32, 34 in the door leaf 12 and insertion of the desired type of lock nut 64, 264 and after corresponding attachment of the actuating rods 18, the cap part 70 or 170 can be placed, which can be seen in more detail in FIG. 13 in a first embodiment. The cap part 70 has a central opening 132 in the cap base 130 for the storage of the nut and an eye 134 arranged above and below the central opening 132 and projecting into the interior of the cap with a countersunk bore 136 for receiving the fastening screw 72. Two longer side walls 140 extend parallel to the guide slots 138, as do perpendicular shorter side walls 142, which connect the latter to the eye 134 and from the end edges of which a support and guide wall 143 protrudes into the interior of the cap, each leading to the longer one Sidewall 140 is arranged parallel at a distance and forms a part of the guide slot 138 with this. This cap part 70 fits e.g. to the base parts 68, 168, 268 according to Fig. 3, 4, 17, 19, the wall 143 up to the inner end face e.g. the base part 68 is sufficient. The pressure exerted by the fastening screws 72 is, however, essentially transmitted from the end faces of the side walls 142, 140 to the edge areas of the door leaf opening 32 (according to FIG. 1) and serves to securely hold the closure in the door leaf.

In den Fig. 12 und 17 ist jeweils eine etwas abgewandelte Ausführungsform des entsprechenden Basisteils zu erkennen, bezeichnet mit Fig. 27 bzw. Fig. 28, die gegenüber dem bisher beschreibenen Basisteil insofern abgewandelt sind, als der in das Türblatt hineinreichende Teil soweit verkürzt ist, daß die Einsenkung 94, die bisher zur Lagerung der Nuß gedient hat, wegfällt. Diese Basisteile sind für eine Ausführungsform vorgesehen, die in Fig. 20 näher erläutert ist, bei welcher Ausführungsform das Basisteil zweiteilig ist und aus einem Schlüsselfangteil 144 und einem Lagerteil 146 besteht, welches Lagerteil mit dem zugehörigen Kappenteil 170 im wesentlichen gleichen Aufbau zeigt, wie aus der Fig. 21, die das Kappenteilo 170 zeigt, und der Fig. 22, die eine Wiedergabe des Lagerteils 146 ist, deutlich wird. Die beiden Teile unterscheiden sich lediglich dadurch, daß von dem einen Teil, hier ist es das Lagerteil 146, von den Rändern der eingesenkten Bohrungen 236 aus von der Verbindungsebene 145 für die beiden Teile 146, 170 in Richtung des anderen Teils vorspringende Nasen bzw. ringförmige Vorsprünge 148 ausgehen, die in in dem gegenüberliegenden Teil, hier das Kappenteil 170 angeordneten Rücksprüngen, hier entsprechend erweiterte eingesenkte Bohrungen 336, passend eingreifen und eine gegenseitige Verriegelung der beiden Teile bewirken. Man kann aber auch durch die eingesenkten Bohrungen 236, 336 Hohlnieten führen und durch diese die gegenseitigen Verriegelung der Teile bewirken, woraufhin die beiden Teile völlig identisch gemacht werden können. Mit Hilfe von Hohlnieten wäre eine Vormontage des Schloßnuß-, Ritzel- und Stangelagers im Herstellerwerk möglich.FIGS. 12 and 17 each show a slightly modified embodiment of the corresponding base part, designated by FIGS. 27 and 28, which are modified compared to the base part described so far in that the part reaching into the door leaf is shortened to the extent that the depression 94, which has previously served to store the nut, is eliminated. These base parts are provided for an embodiment which is explained in more detail in FIG. 20, in which embodiment the base part is in two parts and consists of a key catch part 144 and a bearing part 146, which bearing part with the associated cap part 170 shows essentially the same structure as from 21, which shows the cap part 170, and FIG. 22, the one Playback of the bearing part 146 is clear. The two parts differ only in that from one part, here it is the bearing part 146, from the edges of the countersunk bores 236 from the connecting plane 145 for the two parts 146, 170 projecting lugs or ring-shaped in the direction of the other part Extend projections 148, which engage in recesses arranged in the opposite part, here the cap part 170, here correspondingly enlarged recessed bores 336, and bring about a mutual locking of the two parts. But you can also lead through the countersunk holes 236, 336 hollow rivets and this cause the mutual locking of the parts, whereupon the two parts can be made completely identical. With the help of hollow rivets, a pre-assembly of the lock nut, pinion and rod bearing would be possible in the manufacturing plant.

Der weitere Vorteil ist, daß dieses ggf. vormontierte Schloßnuß-, Ritzel- und Stangenlager mit verschiedenartigen den Rest des Basisteils bildenden Schlüsselfängen kombiniert werden kann, wie sie bereits in den Fig. 27 und 28 dargestellt sind. Durch Identität der beiden die Schloßnuß-, Ritzel- und Stangenlagerung bildenden Teile werden die Herstellungskosten und die Lagerhaltungskosten weiter verringert und es entsteht ein Bausatzsystem, das mit sehr wenigen Teilen außerordentlich vielgestaltige Anwendungsmöglichkeiten erlaubt. So kann das in Fig. 20 dargestellte Schloßnuß-, Ritzel- und Stangenlager, bestehend aus den Teilen 368 und 170, statt mit dem dort dargestellten Schlüsselfangteil 144 nebst zugehörigem, in Fig. 25 dargestellten Vierkanteinsatz 208 (der in das ebenfalls in Fig. 25 dargestellte völlig symmetrische Ritzel 262 einsteckbar ist) mit einer Schwenkhebelbasisplatte 468 verknüpft werden, wie sie als Alternative in Fig. 28 dargestellt ist und welche Schwenkhebelbasisplatte 468 mit eingebautem Schwenkhebel 114 in Fig. 29 zu erkennen ist, wobei der Schwenkhebellagerzapfen 210 sich von dem in Fig. 18 dargestellten Schwenkhebellagerzapfen 110 durch eine vergrößerte, an den Bohrungsdurchmesser des Basisteils 146 angepaßten Lagerteil 150 un dem davon ausgehenden Vierkant 152 zum Einstecken in die entsprechende Vierkantöffnung 154 des in Fig. 25 dargestellten Ritzels 262 unterscheidet. Festgehalten wird das Schwenklager 210 mit Hilfe eines vom Vierkant 152 ausgehenden Bolzens, auf dem eine Schraube aufsetzbar ist, die in Fig. 29 zu erkennen. Wie die Fig. 20 weiterhin verdeutlicht, kann auch das Schlüsselfangteii 144 wiederum mehrteilig sein, um erhöhte Flexibilität zu erreichen. So zeigt die Fig. 20 oben rechts einen Schlüsselfang 144 mit einem Einsatz 154, der in Fig. 26 getrennt dargestellt ist und den Schlüsselfang 144 an sogenannte Doppelbartschlüssel, siehe Bezugszahl 156 in Fig. 26, anpaßt. Neben dem links dargestellten Doppelbarteinsatz 154 ist rechts noch ein entsprechend abgewandelter Einsatz für Vierkantschlüssel dargestellt, siehe die Bezugszahl 254.Another advantage is that this possibly pre-assembled lock nut, pinion and rod bearing can be combined with various key catches forming the rest of the base part, as already shown in FIGS. 27 and 28. Through the identity of the two parts forming the lock nut, pinion and rod bearing, the manufacturing costs and the storage costs are further reduced and a kit system is created which allows extremely diverse application possibilities with very few parts. Thus, the lock nut, pinion and rod bearing shown in FIG. 20, consisting of the parts 368 and 170, instead of the key catch part 144 shown there and the associated square insert 208 shown in FIG. 25 (which also in the FIG. 25 shown completely symmetrical pinion 262 can be inserted) with a pivot lever base plate 468, as shown as an alternative in FIG. 28 and which pivot lever base plate 468 with built-in pivot lever 114 can be seen in FIG. 29, the pivot lever bearing pin 210 being different from the one in FIG 18 shown by an enlarged bearing part 150 adapted to the bore diameter of the base part 146 and the square 152 proceeding therefrom for insertion into the corresponding square opening 154 of the pinion 262 shown in FIG. The pivot bearing 210 is held in place with the aid of a bolt extending from the square 152, on which a screw can be placed, which can be seen in FIG. 29. As FIG. 20 further clarifies, the key catch part 144 can in turn be in several parts in order to achieve increased flexibility. Thus, FIG. 20 shows a key catch 144 at the top right with an insert 154, which is shown separately in FIG. 26 and adjusts the key catch 144 to so-called double-bit keys, see reference number 156 in FIG. 26. In addition to the double-bit insert 154 shown on the left, a correspondingly modified insert for square keys is also shown on the right, see reference number 254.

Fig. 23 zeigt unten den Schlüsselfang 144 gemäß Fig. 20 mit Einsatz 154 und Vierkantsteckverbindung 208 nochmal getrennt von vorn und von der Seite, wobei der Schlüsselfang 144 auch wiederum einen Rücksprung 120 zur Aufnahme ggf. einer Abdeckplatte 188 besitzt. Ähnlich aufgebaut sein könnte eine einfacher verschließbarer Hebelverschluß, siehe Fig. 23 oben. Der für den in Fig. 26 dargestellten Einsatz 154 bzw. 254 vorgesehene Schlüsselfang mit einer entsprechenden Einsekung für Einsatzorsprünge 158 ergibt sich aus Fig. 24. Diese Figur läßt auch die genauere Form des Rücksprungs 120 zur Aufnahme entsprechender Nasen 160 der Zusatzabdeckung 188 erkennen.FIG. 23 shows the key catch 144 according to FIG. 20 with insert 154 and square plug connection 208 again separately from the front and from the side, the key catch 144 again having a recess 120 for receiving a cover plate 188, if necessary. A simple lockable lever lock could be constructed similarly, see FIG. 23 above. The key catch provided for the insert 154 or 254 shown in FIG. 26 with a corresponding indentation for insert or projections 158 results from FIG. 24. This figure also shows the more precise shape of the recess 120 for receiving corresponding lugs 160 of the additional cover 188.

Fig. 14 zeigt ein Basisteil 568 ähnlich dem der Fig. 17, bei dem ebenfalls auswechselbare Schlüsselfänge vorgesehen sind. Das Basisteil ist hier besonders schmal gestaltet und die Schlüsselfangdrehsicherung durch axial in Richtung der Schloßnuß gerichtete Verriegelungsfinger 569, die zwischen sich rinchabschnittförmige Zwischenräume 560 bilden, in die entsprechenden Vorsprünge eines Schlüsselfangeinsatzes eingreifen können, verwirklicht.FIG. 14 shows a base part 568 similar to that of FIG. 17, in which interchangeable key catches are also provided. The base part is particularly narrow here and the key catch rotation lock is realized by locking fingers 569 which are axially directed in the direction of the lock nut and which form interstices 560 between them, which can engage in the corresponding projections of a key catch insert.

Fig. 31 zeigt in einer Ansicht von vorn, von oben und im Axialschnitt eine Schwenkhebelbetätigung für den erfindungsgemäßen Stangenverschluß, der als Besonderheit ein Basisteil 668 aufweist, das am unteren Ende eine Abdeckkappe 669 zum Umschließen des Zylinders 164 aufweist, wobei die Kappe 669 mittels Schrauben 672, die in entsprechende Bohrungen 616 (ähnlich in Fig. 14 zu erkennen, siehe dort die Bezugszahl 516) des Basisteils 668 einschraubbar sind, am Basisteil befestigt ist und dabei das Türblatt 12 einklemmt. Im oberen Bereich des Basisteils findet sich in einem passenden Rücksprung eine O-Ring-Dichtung 673. Wird nun noch zwischen Basisteilauflagefläche und Türblatt ein Dichtungsblatt gelegt, das zumindest die die Durchbrüche 32, 34 umgebenden Bereiche 674, 675 erfaßt, und sind die Köpfe der Schrauben 672 dicht umschlossen und ist auch zwischen Kappenrand 676 und Türblatt eine Dichtung vorgesehen, kann der Verschluß auch außerhalb des Verkantungsraums 10 und innerhalb des Abdichtraums 9 angeordnet werden, wie Fig. 31 zeigt, ohne daß der Verschluß die Raumabdichtung gefährden würde.Fig. 31 shows a view from the front, from above and in axial section of a pivot lever actuation for the rod lock according to the invention, which has a special feature of a base part 668, which has a cover cap 669 at the lower end for enclosing the cylinder 164, the cap 669 by means of screws 672, which can be screwed into corresponding bores 616 (similar in FIG. 14, see reference number 516 there) of the base part 668, is fastened to the base part and thereby clamps the door leaf 12. In the upper area of the base part there is an O-ring seal 673 in a suitable recess. If a sealing sheet is now placed between the base part support surface and the door leaf, which covers at least the areas 674, 675 surrounding the openings 32, 34, and are the heads of the Screws 672 are tightly enclosed and a seal is also provided between the cap edge 676 and the door leaf, the closure can also be arranged outside the canting space 10 and inside the sealing space 9, as shown in FIG. 31, without the closure endangering the space seal.

Bei der dargestellten Montageart ist die Verwendung einer Flügelzunge 8 möglich. Dazu läßt sich die Schloßnuß 664 so ausgestalten, daß sie eine Anlagefläche 676 mit axialer prismatischer Einsenkung und Gewindebohrung zur drehstarren Befestigung einer Flügelzunge 9 aufweist. Eine solche Schloßnuß 664 kann man aus einer Schwenkhebellagerung ähnlich der Fig. 18 und einem Ritzel ähnlich der Fig. 25 oder 30 zuammensetzen und in einem Schloßkasten aus Teilen ähnlich gemäß Fig. 21 und 22 einsetzen. Die Flügelzunge 8 ist dabei mit einem Ansatz 677 versehen, der aufgrund der Befestigung mittels Schraube 678 am Ritzel anleigt und gleichzeitig eine Drehlagerfläche im Schloßkastenteil 670 bildet.In the type of installation shown, the use of a wing tongue 8 is possible. For this purpose, the lock nut 664 can be designed in such a way that it has a contact surface 676 with an axial prismatic depression and threaded hole for the torsionally rigid fastening of a wing tongue 9. Such a lock nut 664 can be assembled from a pivot lever bearing similar to FIG. 18 and a pinion similar to FIG. 25 or 30 and used in a lock case made of parts similar to FIGS. 21 and 22. The wing tongue 8 is provided with a shoulder 677 which, due to the fastening by means of screw 678, abuts the pinion and at the same time forms a pivot bearing surface in the lock case part 670.

Bei symmetrischen Schloßkästen wie in Fig. 31 muß die Schloßnuß 664 verhältnismäßig weit bezüglich der Außenfläche des Schloßkastens zurückspringen, damit-bei Dornverschlüssen--der Dorn nicht zu weit herausragt. Daher auch das teife Eindringen des Flügelzungenansatzes 677.In the case of symmetrical lock cases as in FIG. 31, the lock nut 664 must spring back relatively far with respect to the outer surface of the lock case, so that - in the case of pin locks - the pin does not protrude too far. Hence the steep penetration of the wing tongue extension 677.

Der beschriebene Stangenverschluß läßt sich besonders einfach dadurch in dem Verkantungsraum einer Blechsranktür montieren, daß zunächst die Stangenführungen 20 über die Stangen 18 geklipst werden, anschließend die Stangenführungen 20 auf die Stehbolzen gesteckt und mit einer Mutter verschraubt (oder alternativ mit einer Schraubbolzenbefestigung festgelegt werden), daß dann das das Schlüsselschild bildende Basisteil 68 (ggf. nach Einstecken entsprechender Zusatzteile wie Dorneinsatz 154, Lagerteil 146 und/oder Abdeckplatte 188) von außen montiert wird, daß dann das Ritzel 62 mit dem zugehörigen Betätigungsdorn, z.B. 208 in Fig. 26, eingesteckt und dann das Kappenteil 70 übergestülpt und das ganze mittels der zwei Schrauben 72 festgelegt wird. Dabei wird das Schaltschranktürblech fest zwischen das Schlüsselschild oder Basisteil 68 und das übergestülpte Kappenteil 70 und ggf. 669 eingeklemmt. Von den Stangen auf das Schloß übertragene Verschiebungskräfte werden dabei von dem Basisteil aufgenommen, nicht von einer Klemmverschraubung wie beim Stand der Technik, so daß gegenüber älteren Konstruktionen die Gefahr des Lockerns der Befestigung nicht gegeben ist.The rod lock described can be particularly easily installed in the canting space of a sheet-metal cabinet door by first clipping the rod guides 20 over the rods 18, then plugging the rod guides 20 onto the stud bolts and screwing them with a nut (or alternatively, fixing them with a bolt fastening), that then the base part 68 forming the key plate (possibly after inserting corresponding additional parts such as mandrel insert 154, bearing part 146 and / or cover plate 188) is mounted from the outside, that then the pinion 62 with the associated actuating mandrel, for example 208 in FIG. 26, and then the cap part 70 is put over and the whole is fixed by means of the two screws 72. The control cabinet door panel is firmly clamped between the key plate or base part 68 and the slipped cap part 70 and possibly 669. Displacement forces transmitted from the rods to the lock are absorbed by the base part, not by a compression fitting as in the prior art, so that there is no risk of the fastening loosening compared to older designs.
