Description

Die Erfindung bezieht sich auf ein Schloß für eine Tür, ein Fen­ster od. dgl. mit mindestens einem schlüsselbetätigbaren Riegel­glied, das mittels eines wenigstens ein Ritzel aufweisenden Ge­triebes verschiebbar ist, wobei das in einem Schloßkasten od. dgl. gelagerte Ritzel als radial geschlitzter Ring ausgebildet ist, der von einem Schließzylinder durchsetzt ist, dessen exzent­risch zum Ritzel gelagerter Schließbart in den Schlitz des Rit­zels eingreift und mit letzterem antriebsverbunden ist. Ein Schloß dieser Art ist bereits bekannt. Bei dem Schließzylinder kann es sich sowohl um einen handelsüblichen Profilzylinder als auch um einen gebräuchlichen Rundzylinder handeln. Bei letzterem ist der im Querschnitt kreisförmige Zylinderteil größer als beim normalen Profilzylinder. Beide sind jedoch mit einem flachen, an seinem freien Ende abgerundeten Gehäuseteil ausgestattet, welches an seinem inneren Ende eine Ausnehmung für das Hindurchdrehen des Schließbarts aufweist. Außerdem ist der flache Gehäuseteil mit einem Gewinde versehen, durch welches eine nur bei offener Tür zugängliche Befestigungsschraube hindurchgedreht wird. Der Schließbart befindet sich an einem Antriebsring, der in bekannter Weise mittels eines zum Schloß gehörigen Schlüssels drehbar ist. Die Mitten des geschlitzten Ritzels und des Antriebsrings sind in Längsrichtung des flachen Gehäuseteils gegeneinander versetzt, weswegen der Schliebart exzentrisch zum Ritzel gelagert ist, das heißt, der Flugkreis des Schließbarts verläuft nicht konzentrisch zur geometrischen Ritzelachse.The invention relates to a lock for a door, a window or the like. With at least one key-operated locking member which is displaceable by means of a gear having at least one pinion, the pinion mounted in a lock case or the like being designed as a radially slotted ring is, which is penetrated by a lock cylinder, the eccentrically mounted to the pinion engages in the slot of the pinion and is drive-connected to the latter. A lock of this type is already known. With the lock cylinder can be both a commercially available profile cylinder and a conventional round cylinder. In the latter, the cylindrical part with a circular cross section is larger than in the normal profile cylinder. However, both are equipped with a flat housing part which is rounded at its free end and has a recess at its inner end for rotating the locking bar. In addition, the flat housing part is provided with a thread through which a fastening screw, which is only accessible when the door is open, is screwed through. The lock bit is located on a drive ring which can be rotated in a known manner by means of a key belonging to the lock. The centers of the slotted pinion and the drive ring are offset from one another in the longitudinal direction of the flat housing part, which is why the slide type is mounted eccentrically to the pinion, that is to say the trajectory of the locking bit does not run concentrically with the geometric pinion axis.

Das Schloßgehäuse besitzt an seinem Boden und Deckel je einen Durchbruch, durch welchen man den Schließzylinder hindurchstecken kann. Dieser Durchbruch ist schlüssellochartig. Seine genaue Ge­stalt hängt vom jeweils zu verwendenden Schließzylinder ab. Nach dem Hindurchstecken des Schließzylinders durch diese Schloßka­stenausstanzungen od. dgl. wird der Schießzylinder in radialer Richtung des Ritzels bzw. in Längsrichtung seines flachen Gehäu­seteils so weit verschoben, bis die Gewindebohrung des flachen Schließzylindergehäuseteils mit der Achse der Befestigungsschrau­ be fluchtet. Wenn letztere vollständig eingeschraubt ist, hat der Schließzylinder seine endgültige gesicherte Stellung im Schloß eingenommen.The lock housing has an opening on its base and cover, through which the lock cylinder can be inserted. This breakthrough is like a keyhole. Its exact shape depends on the locking cylinder to be used. After inserting the lock cylinder through these lock case punchings or the like. The shooting cylinder is displaced in the radial direction of the pinion or in the longitudinal direction of its flat housing part until the threaded bore of the flat lock cylinder housing part with the axis of the fastening screw be aligned. When the latter is fully screwed in, the lock cylinder has assumed its final, secure position in the lock.

Außer den normalen handelsüblichen Profilzylindern (sogenannte Hahn-Zylinder) verwendet man, wie gesagt, auch Rundzylinder, je­doch gibt es hier Unterschiede in der Lage der Achse des An­triebsrings, die exzentrisch zum im Querschnitt kreisförmigen Ge­häuseteil angeordnet ist. Im Zusammenhang damit gibt es dann auch radiale Längenunterschiede der Schließbärte. Der längere Schließ­bart hat selbstverständlich einen größeren Flugkreisdurchmesser als der kürzere. Die Außenkontur dieser unterschiedlichen Rundzy­linder ist aber bei den gebräuchlichen Ausführungsformen gleich, so daß man hinsichtlich der Schloßdurchbrüche für die Rundzylin­der die gleiche Form verwenden kann.In addition to the normal commercially available profile cylinders (so-called Hahn cylinders), round cylinders are also used, as mentioned, but there are differences in the position of the axis of the drive ring, which is arranged eccentrically to the housing part which is circular in cross section. In connection with this there are also radial differences in length of the mustaches. The longer lock bit naturally has a larger flight circle diameter than the shorter one. The outer contour of these different round cylinders is, however, the same in the customary embodiments, so that the same shape can be used with regard to the lock openings for the round cylinders.

Das geschlitzte Ritzel wird, wie gesagt, in axialer Richtung vom Schließzylinder durchsetzt. Aus diesem Grunde kann es nur an sei­nem Außenumfang gelagert werden. Diese Lagerung ist bei herkömm­lichen Profilzylindern (Hahn-Zylindern) problemlos. Sie kann je­doch bei Rundzylindern mit langem Schließbart schwierig werden, weil sich der Außendurchmesser des Ritzels und der Flugkreis des Schließbarts schneiden. Andererseits ist man aber bestrebt, sol­che Schlösser universell auszubilden, damit alle gebräuchlichen Rund-und Profilzylinder eingesetzt werden können. Hierin ist auch die Aufgabe der vorliegenden Erfindung zu sehen.As stated, the slotted pinion is penetrated in the axial direction by the locking cylinder. For this reason, it can only be stored on its outer circumference. This storage is easy with conventional profile cylinders (Hahn cylinders). However, it can be difficult for round cylinders with a long lock bit because the outer diameter of the pinion and the flight circle of the lock bit intersect. On the other hand, however, efforts are being made to design such locks universally so that all customary round and profile cylinders can be used. This is also the object of the present invention.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Schloß gemäß dem Oberbegriff des Anspruchs 1 entsprechend dem kennzeich­nenden Teil dieses Anspruchs ausgebildet ist. Der in die kreisbo­genförmige Nut zwischen der Führungswand und der Führungsleiste eingreifende Führungsrand des Ritzels gewährleistet eine sichere Ritzelführung bei der Drehung und die mondsichelförmige Gestalt der Führungsleiste ermöglicht trotz der exzentrischen Anordnung des Schließbartflugkreises gegenüber der geometrischen Ritzel­drehachse bzw. der Führungswand auch bei vergleichsweise langem Schließbart dessen ungehinderte Drehung. Weil die äußeren Abmes­sungen der verschiedenen Rundzylinder-Gehäuse gleich sind, und auch hinsichtlich des radialen Abstands des Gewindes für die Be­festigungsschraube von der geometrischen Achse des runden Schließzylindergehäuseteils keine Unterschiede vorhanden ist, sondern nur die Flugkreise der Schließbärte unterschiedlich groß sind und unterschiedliche Exzentrizitäten der Drehmittelpunkte vorliegen, richtet sich die Innenkontur bzw. der Radius der In­nenwandung der mondsichelförmigen Führungsleiste nach dem Flug­kreis des längsten Schließbarts der gebräuchlichen Rundzylinder. Damit ist dann auch automatisch für kürzere Schließbärte und für Schließbärte von normalen handelsüblichen Profilzylindern genü­gend Platz vorhanden.This object is achieved in that the lock is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim. The guide edge of the pinion, which engages in the arcuate groove between the guide wall and the guide bar, ensures secure pinion guidance during rotation, and the crescent-shaped shape of the guide bar enables the unhindered, despite the eccentric arrangement of the cam-type flight circle with respect to the geometric pinion rotation axis or the guide wall, even with a comparatively long cam type Rotation. Because the outer dimensions of the various round cylinder housings are the same, and there are no differences with regard to the radial spacing of the thread for the fastening screw from the geometric axis of the round lock cylinder housing part, only the flight circles of the mustaches are different in size and there are different eccentricities of the centers of rotation , the inner contour or the radius of the inner wall of the crescent-shaped guide rail depends on the flight circle of the longest locking bar of the usual round cylinders. This means that there is automatically enough space available for shorter mustaches and for beards of normal commercially available profile cylinders.

Die mondsichelförmige Führungsleiste erstreckt sich vorteil­hafterweise über einen Winkel von ca. 180°, wodurch eine gute Führung des Ritzels gewährleistet ist und für alle üblichen Schließzylinder und Einbauarten genügend Bewegungsraum für den Schließbart zur Verfügung steht. Der Winkel sollte möglichst nicht kleiner als etwa 150° sein und sein Maximalwert liegt für die heute gebräuchlichen Schlösser und Schließzylinder bei ca. 190°.The crescent-shaped guide bar advantageously extends over an angle of approximately 180 °, which ensures good guidance of the pinion and sufficient room for movement for all conventional locking cylinders and types of installation Lock bit is available. If possible, the angle should not be less than about 150 ° and its maximum value for today's locks and lock cylinders is around 190 °.

Eine Weiterbildung der Erfindung sieht vor, daß die Führungslei­ste und die Führungswand an einem mit dem Schloßkasten verbunde­nen Führungskörper angebracht, insbesondere angeformt sind. Durch den separat gefertigten Führungskörper erhält man ein besonders universelles Schloß, weil der Führungskörper gegebenenfalls durch ein anderes Schloßteil ersetzt werden kann, welches demselben Zwecke dient, aber eine weitere Variation der Schließzylinder zuläßt.A further development of the invention provides that the guide bar and the guide wall are attached, in particular molded, to a guide body connected to the lock case. The separately manufactured guide body provides a particularly universal lock, because the guide body can possibly be replaced by another lock part which serves the same purpose, but permits a further variation of the lock cylinder.

Der Führungskörper ist in bevorzugter Weise aus Druckgußmaterial, insbesondere aus Zinkdruckguß gefertigt, was eine hohe Genauig­keit gewährleistet und damit letztlich zu einer Leichtgängigkeit und Robustheit dieses Schlosses führt. Entsprechendes gilt für die Herstellung des Ritzels.The guide body is preferably made of die-cast material, in particular of die-cast zinc, which ensures high accuracy and thus ultimately leads to the smoothness and robustness of this lock. The same applies to the manufacture of the pinion.

Die Erfindung wird nachstehend anhand der Zeichnung näher erläutert. Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Hierbei stellen dar:

  • Fig. 1 Eine abgebrochene Seitenansichht des Schlosses bei abgenommenen Schloßkastendeckel,
  • Fig. 2 ein Schnitt gemäß der Linie II-II der Fig. 1
The invention is explained below with reference to the drawing. The drawing shows an embodiment of the invention. Here represent:
  • 1 is a broken side view of the lock with the lock case cover removed,
  • 2 shows a section along the line II-II of FIG. 1st

Am Boden 1 und am Deckel 2 eines Schloßkastens 3 befinden sich je eine im wesentlichen schlüssellochartige Durchstecköffnung 4 bzw. 5 für ein Schließzylinder 6. Dieser besitzt ein flaches Gehäuse­teil 7 und ein im Querschnitt kreisrundes Gehäuseteil 8. In letz­terem ist ein Antriebsring 9 exzentrisch drehbar gelagert, von welchem radial ein Schließbart 10 absteht. Das flache Gehäuseteil 7 besitzt einen Durchbruch 11, welcher das Durchqueren dieses Ge­häuseteils durch den Schließbart gestattet. Außerdem befindet sich unterhalb dieses Durchbruchs eine Gewindebohrung 12 zum Ein­drehen einer Befestigungsschraube 13, deren Kopf nur bei geöffne­ter Tür bzw. geöffnetem, mit diesem Schloß ausgestattetem Fenster zugänglich ist.On the bottom 1 and on the cover 2 of a lock case 3 there are each an essentially keyhole-like push-through opening 4 or 5 for a lock cylinder 6. This has a flat housing part 7 and a housing part 8 with a circular cross section. In the latter, a drive ring 9 is rotatably mounted eccentrically , from which a locking bit 10 protrudes radially. The flat housing part 7 has an opening 11, which allows the passage of this housing part through the lock bit. In addition, below this opening there is a threaded bore 12 for screwing in a fastening screw 13, the head of which is accessible only when the door is open or the window equipped with this lock is open.

Der flache Gehäuseteil 7 durchsetzt den radialen Schlitz 14 eines geschlitzten ringförmigen Ritzels 15. Dessen Innendurchmesser 16 ist so dimensioniert, daß auch der Schließzylinder mit dem größ­ten runden Gehäuseteil 8 hindurchgesteckt werden kann. Der Schließzylinder wird allerdings nach dem Hindurchstecken durch das Ritzel 15 in radialer Richtung, mit seinem flachen Gehäuse­teil 7 voran in Pfeilrichtung 17, also normalerweise nach unten hin verschoben, bis seine Gewindebohrung 12 mit der Achse der Be­festigungsschraube 13 fluchtet, so daß letztere eingeschraubt werden kann. Dabei hintergreift dann der runde Gehäuseteil 8 ge­mäß Fig. 1 das Ritzel an seinem jeweils unteren, der Schraube 13 zugeordneten Bereich.The flat housing part 7 passes through the radial slot 14 of a slotted ring-shaped pinion 15. Its inner diameter 16 is dimensioned such that the lock cylinder with the largest round housing part 8 can also be inserted. The locking cylinder is, however, after being pushed through the pinion 15 in the radial direction, with its flat housing part 7 first in the direction of the arrow 17, that is normally moved downwards until its threaded bore 12 is aligned with the axis of the fastening screw 13, so that the latter can be screwed in . The round housing part 8 according to FIG. 1 then engages behind the pinion at its lower area, which is assigned to the screw 13.

Die geometrische Achse des Ritzels 15 ist mit 18 bezeichnet. Auf der vertikalen Symmetrieachse 19 nach unten hin versetzt befindet sich die geometrische Achse 20 des Antriebsrings 9 mit dem Schließbart 10.The geometric axis of the pinion 15 is designated 18. On The vertical axis of symmetry 19 offset downward is the geometric axis 20 of the drive ring 9 with the locking bit 10.

In das Schloß können auch Schließzylinder anderer Bauart, insbe­sondere andere Rundzylinder eingesetzt werden. Ein weiterer der­artiger Rundzylinder hat beispielsweise einen Antriebsring mit einem kürzeren Schließbart 21, dessen geometrische Achse mit 22 bezeichnet ist. Die Exzentrizität ist hier etwas geringer als diejenige der Ausführung mit dem Schließbart 10. Außerdem kann ein entsprechend kürzerer Durchbruch 23 vorhanden sein. Die Außenabmessungen dieser beiden Schließzylinder sind jedoch gleich, ebenso der Abstand der Gewindebohrungen 12 vom in Fig. 1 oberen Ende dieses Schließzylinders.Other types of lock cylinders, in particular other round cylinders, can also be used in the lock. Another such round cylinder has, for example, a drive ring with a shorter cam 21, the geometric axis of which is designated 22. The eccentricity here is somewhat less than that of the embodiment with the lock bit 10. In addition, a correspondingly shorter opening 23 can be present. However, the outer dimensions of these two locking cylinders are the same, as is the distance between the threaded bores 12 from the upper end of this locking cylinder in FIG. 1.

Weil der Schließzylinder, wie gesagt, das ringförmige Ritzel in axialer Richtung durchsetzt, kann er nur an seinen Außenumfang gelagert werden. Die Lagerung muß jedoch so ausgebildet sein, daß alle handelsüblichen Rundzylinder, aber auch die normalen ge­bräuchlichen Profilzylinder mit im Durchmesser wesentlich kleine­rem rundem Gehäuseteil in dieses Schloß eingesetzt werden können und jeweils genügend Platz für die Drehbewegung des Schließbarts vorhanden ist. Maßgeblich ist also der Flugkreis des Schließbarts gegenüber dem zumindest bei den Rundzylindern exzentrisch ange­ordneten Ritzel. Die Ritzelgröße ist bei derartigen Schlössern zumindest was den Außendurchmesser angeht nicht frei wählbar, weil der vorhandene Platz beschränkt ist. Das mittels des Schlüs­sels und damit des Schließbarts angetriebene Ritzel arbeitet in bekannter Weise mit einem Getriebe 24 des Schlosses zusammen, das eine festliegende Übersetzung und damit auch einen ganz bestimm­ten Platzbedarf hat. Diese Getriebe sind bekannt, weswegen sie im einzelnen nicht näher beschrieben werden. Auf jeden Fall wirkt das letzte Ritzel dieses Getriebes auf eine Zahnstange ein, wel­che mit einer Treibstange 25 gekuppelt ist, die in nicht darge­stellter Weise einen Verriegelungszapfen od. dgl. trägt, der mit einem Schließblech am festen Rahmen zusammenwirkt. Außerdem kann über dieses Getriebe und bekannte Zwischenglieder ein Schloßrie­gel 26 im Sinne des Doppelfpeils 27 hin und her verschoben, d.h. ein- und ausgeriegelt werden.Because, as stated, the locking cylinder passes through the ring-shaped pinion in the axial direction, it can only be supported on its outer circumference. However, the storage must be designed so that all commercially available round cylinders, but also the normal profile cylinders with a round housing part that is much smaller in diameter, can be used in this lock and that there is sufficient space for the rotary movement of the locking bar. The decisive factor is the flight circle of the locking bar compared to the pinion, which is arranged eccentrically at least in the case of the round cylinders. With such locks, the pinion size cannot be freely selected, at least as far as the outer diameter is concerned, because the available space is limited. The pinion driven by the key and thus the lock bit works in a known manner with a gear 24 of the lock, which has a fixed translation and thus also a very specific space requirement. These gears are known, which is why they are not described in detail. In any case, the last pinion of this gear acts on a rack which is coupled to a drive rod 25 which, in a manner not shown, carries a locking pin or the like which interacts with a striking plate on the fixed frame. In addition, a lock bolt 26 in the sense of the double arrow 27 can be moved back and forth, ie locked and unlocked, via this transmission and known intermediate links.

Probleme der Lagerung treten, wie gesagt, insbesondere dann auf, wenn der Schließbart des Rundzylinders in eingebautem Zustand über den Außendurchmesser des anzutreibenden Ritzels 15 vorsteht, wie dies beim Ausführungsbeispiel nach Fig. 1 der Fall ist. In diesem Falle darf nämlich im Bewegungsbereich des Schließbarts keine hochstehende Kante od. dgl. vorhanden sein.As mentioned, problems with storage occur in particular when the cam lock of the round cylinder projects in the installed state beyond the outer diameter of the pinion 15 to be driven, as is the case with the exemplary embodiment according to FIG. 1. In this case, there must be no raised edge or the like in the range of movement of the locking bar.

Um nun trotzdem eine einwandfreie Lagerung des Ritzels zu gewähr­leisten, andererseits aber auch die Verwendung solcher Schließ­zylinder zu ermöglichen, deren Schließbart in radialer Richtung über das exzentrische Ritzel vorsteht, wurde dieses Schloß in der im Anspruch eins beschriebenen Weise ausgebildet. Das Schloßge­ häuse besitzt demnach eine in ihrem Bereich oberhalb der Achse 18 kreisbogenförmige Führungswand 28 und das Ritzel 15 ist mit einem hierzu konzentrischen, axial vorstehenden kreisringförmigen Füh­rungsrand 29 ausgestattet. Dieser entsteht beim Ausführungsbei­spiel dadurch, daß das Ritzel an seiner in Fig. 2 linken Stirn­seite mit einer konzentrischen, umlaufenden Ringnut 30 ausgestat­tet ist. Ihr Querschnitt kann halbkreisförmig oder in vergleich­barer Weise gestaltet sein.In order to ensure proper storage of the pinion anyway, but on the other hand also to enable the use of such lock cylinders, the lock bit of which projects in the radial direction over the eccentric pinion, this lock was designed in the manner described in claim one. The Schloßge Accordingly, the housing has an arcuate guide wall 28 in its area above the axis 18 and the pinion 15 is provided with an axially projecting annular guide edge 29 which is protruding from it. In the exemplary embodiment, this arises from the fact that the pinion on its left-hand end face in FIG. 2 is equipped with a concentric, circumferential annular groove 30. Their cross section can be semicircular or in a comparable manner.

Der Führungsrand 29 wird von einer mondsichelförmigen Führungs­leiste 31 hintergriffen, und zwar gemäß Fig. 1, nur in dem je­weils oberen Bereich, d.h. gegenüberliegend vom flachen Gehäuse­teil 7 des Schließzylinders 6 bzw. in Fig. 1 oberhalb des Ritzel­drehmittelpunkts 18.The guide edge 29 is gripped behind by a crescent-shaped guide bar 31, specifically according to FIG. 1, only in the upper area, i.e. opposite the flat housing part 7 of the lock cylinder 6 or in FIG. 1 above the pinion center 18.

Die mondsichelförmige Führungsleiste ist durch zwei kreisbogen­förmige Zylinderflächen begrenzt. Die äußere verläuft konzen­trisch zur geometrischen Achse 18 des Ritzels 15 bzw. zum Füh­rungsrand 29, während die innere konzentrisch zur Flugbahn des das Ritzel 15 in radialer Richtung am weitestens überragenden Schließbarts 10 bzw. 21 gelegen ist. Damit befindet sich im Flug­kreis bzw. der Flugbahn des Schließbarts 10, 21 kein in Fig. 1 senkrecht zur Bildebene vorstehendes Teil, so daß der Antriebs­ring 9 mit dem Schließbart 10 bzw. ein Antriebsring mit dem Schließbart 21 und etwas anderer Exzentrizität ohne Behinderung um wenigstens 360° gedreht werden können. Trotzdem erreicht man noch eine gute und sichere Führung des Ritzels.The crescent-shaped guide bar is limited by two circular cylindrical surfaces. The outer one is concentric to the geometric axis 18 of the pinion 15 or to the guide edge 29, while the inner one is located concentrically to the trajectory of the locking bar 10 or 21, which projects the most in the radial direction. Thus there is no part projecting perpendicularly to the image plane in FIG. 1 in the flight circle or the trajectory of the locking bit 10, 21, so that the drive ring 9 with the locking bit 10 or a drive ring with the locking bit 21 and some other eccentricity without hindrance by at least Can be rotated 360 °. Nevertheless, the pinion can still be guided well and safely.

Fig. 1 zeigt noch eine federbelastete Transportsperre 32, welche in die Verzahnung des Ritzels 15 eingreift und dessen Lage wäh­rend des Transports sowie vor dem Einsetzen eines Schließzylin­ders gewährleistet. Über das spitze freie Ende der Befestigungs­schraube 13 wird diese Transportsperre gelöst. Beim Herausdrehen der Schraube wird sie wieder aktiviert, so daß nach dem Entfernen des Schließzylinders ein unbeabsichtigtes Verdrehen des Ritzels 15 vermieden wird und man den neuen Schließzylinder problemlos einsetzen kann.Fig. 1 also shows a spring-loaded transport lock 32, which engages in the toothing of the pinion 15 and ensures its position during transport and before the insertion of a locking cylinder. This transport lock is released via the pointed free end of the fastening screw 13. When the screw is unscrewed, it is reactivated so that after the locking cylinder has been removed, an inadvertent rotation of the pinion 15 is avoided and the new locking cylinder can be used without any problems.

Aus Fig. 2 ersieht man, daß die Führungsleiste 31 und die Füh­rungswand 28 an einem Führungskörper 33 ausgebildet sind, welcher vorzugsweise aus Zinkdruckguß besteht und in geeigneter Weise am Boden 1 gehalten bzw. befestigt wird.From Fig. 2 it can be seen that the guide bar 31 and the guide wall 28 are formed on a guide body 33, which preferably consists of die-cast zinc and is held or attached to the floor 1 in a suitable manner.
