Description

Die Erfindung bezieht sich auf einen Antrieb für wenigstens ein Riegelglied, insbesondere zum Verriegeln einer Tür, eines Fensters od. dgl., mit wenigstens einem von einem Ritzel antreibbaren Zahnrad, wobei das Ritzel mittels des Schließbarts eines Schließzylinders drehbar ist und im wesentlichen die Gestalt eines radial geschlitzten Ringes aufweist. Ein derartiger Antrieb ist beispielsweise durch die DE-A-2 831 896 bekanntgeworden. Die maximale Dicke des Ringes, in radialer Richtung gesehen, . bestimmt sich durch den Spaltraum zwischen dem ringförmigen Lagerstück des Schließbarts und dem stegförmigen Gehäuseteil des Schließzylinders im Bereich des Befestigungsgewindes für die Befestigungsschraube. Auch der Zähnezahl sind bei Verwendung eines handelsüblichen Profilzylinders durch die Dicke des flachen Schließzylinderteils zumindest nach oben hin Grenzen gesetzt. Dies hängt damit zusammen, daß in der Regel das sich beispielsweise in einem Schloßkasten befindliche Ritzel montiert wird, bevor der Schließzylinder in das betreffende Schloß eingesetzt wird und man auch später zu Reparaturzwecken den Schließzylinder über den radialen Schlitz des Ritzels herausnehmen können muß.The invention relates to a drive for at least one locking member, in particular for locking a door, a window or the like, with at least one gear which can be driven by a pinion, the pinion being rotatable by means of the locking bar of a locking cylinder and essentially having the shape of a has radially slotted ring. Such a drive has become known, for example, from DE-A-2 831 896. The maximum thickness of the ring, seen in the radial direction,. is determined by the gap between the annular bearing piece of the locking bar and the web-shaped housing part of the locking cylinder in the area of the fastening thread for the fastening screw. When using a commercially available profile cylinder, the thickness of the flat locking cylinder part also limits the number of teeth, at least upwards. This is due to the fact that the pinion located in a lock case, for example, is usually installed before the lock cylinder is inserted into the lock in question and the lock cylinder must be able to be removed later for repair purposes via the radial slot of the pinion.

Es wird nun als nachteilig angesehen, daß bei der vorteilhaften Verwendung eines handelsüblichen Zylinders sowohl die Ritzelgröße als auch die Ritzelzähnezahl der genannten Beschränkung unterworfen sind, weil gelegentlich Bedarf für ein größeres Ritzel und/oder für ein Ritzel mit höherer Zähnezahl besteht. Ein größeres Ritzel wird beispielsweise dann gebraucht, wenn das damit zusammenarbeitende Zahnrad aufgrund anderer Gegebenheiten nicht näher an das Ritzel herangerückt werden kann, so daß die Verwendung von Zwischenrädern notwendig wird. Eine größere Ritzelzähnezahl kann beispielsweise erwünscht sein, um ein anderes Übersetzungsverhältnis und/oder Drehmoment zu bekommen.It is now considered a disadvantage that when a commercially available cylinder is advantageously used, both the pinion size and the number of pinion teeth are subject to the restriction mentioned, because there is occasionally a need for a larger pinion and / or for a pinion with a larger number of teeth. A larger sprocket is used, for example, when the gearwheel working with it cannot be moved closer to the sprocket due to other circumstances, so that the use of idler gears becomes necessary. For example, a larger number of pinion teeth may be desirable in order to obtain a different transmission ratio and / or torque.

Die Aufgabe der Erfindung besteht infolgedessen darin, einen Antrieb der eingangs genannten Art so auszubilden, daß sich trotz Verwendung herkömmlicher Schließzylinder Ritzel mit größerem Durchmesser und damit gegebenenfalls auch größerer Zähnezahl verwenden lassen.The object of the invention is therefore to design a drive of the type mentioned in such a way that, despite the use of conventional locking cylinders, pinions with a larger diameter and thus possibly a larger number of teeth can be used.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß der Antrieb gemäß dem Oberbegriff des Anspruchs 1 entsprechend dem kennzeichnenden Teil dieses Anspruchs ausgebildet ist. Die exzentrische Anordnung der Ritzeldrehachse bezüglich der Drehachse des Schließbarts gestattet die Verwendung verhältnismäßig großer Ritzel, deren Durchmesser lediglich durch andere Fakten einer Begrenzung unterworfen sein kann. Nach unten hin ist der Zahnabstand, in Umfangsrichtung gesehen, wie beim bekannten Stand der Technik durch die Schlitzbreite bzw. die Dicke des flachen Schließzylinderteils des handelsüblichen Schließzylinders begrenzt, während es nach oben hin eine Begrenzung beispielsweise durch die Ausbildung des zugehörigen Zahnrads gibt. Da die Ringbreite praktisch dieselbe ist wie bei den vorbekannten Ritzeln, wird der innere Durchmesser des ringförmigen Ritzels um so größer, je größer man das Ritzel wählt. Dadurch erhält man dann einen zweiten Vorteil, der darin besteht, daß man den Schließzylinder ohne irgendwelche Behinderungen durch das Ritzel problemlos ein-und ausbauen kann. Die bislang übliche Anpassung des Ritzelinnendurchmessers an den Durchmesser des zylindrischen Schließzylinderteils oder eine eventuell zwischengeschalteten ringförmigen Überbrückungsglieds entfällt in vorteilhafter Weise. Nachdem die Zähne bei diesem Ritzel in axialer Richtung abstehen, besitzt es außen eine kreiszylindrische Kontur, mit der es leicht in einer entsprechenden zylindrischen Bohrung oder Aufnahme, beispielsweise eines Schloßkastens od. dgl., gelagert wird. Wenn man von der Ringbreite, der Ringdicke sowie dem Mindestabstand der Zähne einmal absieht, so hat man beim Ritzel dieses Antriebs weit mehr Gestaltungsmöglichkeiten, als das bislang der Fall ist, ohne hinsichtlich des weiteren Antriebs der Riegelglieder Nachteile in Kauf nehmen zu müssen. Die Verwendung eines herkömmlichen Schließzylinders ist nach wie vor möglich, und dessen Einbau wird durch den Verzicht auf eine Passung zwischen Ritzel und Schließzylindergehäuse sogar noch erleichtert. Des weiteren kann man aufgrund der Ausbildung des Ritzels in Art eines Tellerrads besonders kräftige Zähne vorsehen. Insbesondere in radialer Richtung kann man sie länger ausbilden als bei einem stirnverzahnten Rad. Auf diese Weise ist das Ritzel in der Lage, höhere Kräfte zu übertragen als ein Ritzel mit vergleichsweise kleineren Zähnen.To solve this problem, the invention proposes that the drive is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim. The eccentric arrangement of the pinion axis of rotation with respect to the axis of rotation of the locking bar permits the use of relatively large pinions, the diameter of which can only be limited by other facts. At the bottom, the tooth spacing, seen in the circumferential direction, is limited, as in the known prior art, by the slot width or the thickness of the flat locking cylinder part of the commercially available locking cylinder, while there is a limitation, for example by the design of the associated gearwheel. Since the ring width is practically the same as that of the previously known pinions, the larger the pinion selected, the larger the inner diameter of the ring-shaped pinion. This then gives a second advantage, which is that the lock cylinder can be installed and removed without any problems by the pinion. The previously customary adaptation of the pinion inner diameter to the diameter of the cylindrical locking cylinder part or a possibly interposed annular bridging member is advantageously dispensed with. After the teeth on this pinion protrude in the axial direction, it has a circular cylindrical contour on the outside, with which it is easily stored in a corresponding cylindrical bore or receptacle, for example a lock case or the like. If you disregard the ring width, the ring thickness and the minimum distance between the teeth, you have far more design options with the pinion of this drive than has been the case so far without having to accept disadvantages with regard to the further drive of the locking links. The use of a conventional lock cylinder is still possible, and its installation is made even easier by dispensing with a fit between the pinion and the lock cylinder housing. Furthermore, due to the design of the pinion in the manner of a ring gear, particularly strong teeth can be provided. In particular in the radial direction, they can be made longer than in the case of a spur gear. In this way, the pinion is able to transmit higher forces than a pinion with comparatively smaller teeth.

Eine Weiterbildung der Erfindung sieht vor, daß das Zahnrad als stirnverzahntes Rad ausgebildet ist und seine Dicke etwa der Zahnhöhe der Ritzelzähne entspricht. In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß, in Drehrichtung gesehen, die Dicke der Ritzelzähne etwa im Teilkreisbereich kleiner ist als der Zahnabstand, insbesondere der Zahnabstand das zwei- bis vierfache beträgt und mindestens der Dicke des flachen Schließzylinderteils entspricht, und daß das Zahnrad eine dem Übersetzungsverhältnis sowie der Ritzelzähnezahl entsprechende Anzahl von verkürzten Zähnen für den Durchlauf des Schließbarts aufweist. Die Verkürzung des oder der Zähne richtet sich nach den in Frage stehenden Maßen dieses Getriebes sowie der Größe und Zuordnung des Schließbarts zum Ritzel.A further development of the invention provides that the gear is designed as a spur gear and its thickness corresponds approximately to the tooth height of the pinion teeth. In a further embodiment of the invention it is proposed that, viewed in the direction of rotation, the thickness of the pinion teeth is approximately smaller in the pitch circle area than the tooth spacing, in particular the tooth spacing is two to four times and corresponds at least to the thickness of the flat locking cylinder part, and that the gear wheel is one has the number of shortened teeth corresponding to the transmission ratio and the number of pinion teeth for the passage of the locking bar. The shortening of the tooth or teeth depends on the dimensions of this gear in question and the size and assignment of the lock bit to the pinion.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt

  • Fig. 2 eine Seitenansicht der Fig. 1.
In the drawing, an embodiment of the invention is shown. It shows
  • Fig. 1 is a plan view of the drive, wherein the lock cylinder is cut at the height of the lock bit,
  • FIG. 2 is a side view of FIG. 1.

Ein in herkömmlicher Weise ausgebildeter Schließzylinder 1 mit einem flachen Gehäuseteil 2 sowie einem zylindrischen Gehäuseteil 3 besitzt einen drehbaren Schließbart 4. Wenn der Schließzylinder 1 wie beim Ausführungsbeispiel als doppelter Schließzylinder ausgebildet ist, so kann man einen nicht gezeichneten Schfüstei wahlweise von der linken Stirnseite 5 oder der rechten Stirnseite 6 her einstecken. Mit Hilfe dieses Schlüssels läßt sich das den Schließbart 4 aufweisende Drehglied 7 um mindestens volle 360° drehen. Die Befestigung des Schließzylinders in einer entsprechenden Aufnahme eines Schloßkastens oder eines anderen Beschlags einer Tür, eines Fensters od. dgl. erfolgt mit Hilfe einer Schraube, die in das Gewinde 8 eingedreht wird.A lock cylinder 1 designed in a conventional manner with a flat housing part 2 and a cylindrical housing part 3 has a rotatable lock bit 4. If the lock cylinder 1 is designed as a double lock cylinder, as in the exemplary embodiment, then a not shown shovel can either be drawn from the left end face 5 or insert the right front 6. With the help of this key, the rotary member 7 having the locking bit 4 can be rotated by at least a full 360 °. The locking cylinder is fastened in a corresponding receptacle of a lock case or another fitting of a door, a window or the like. With the aid of a screw which is screwed into the thread 8.

Die Drehbewegung des Schließbarts wird in geeigneter Weise in eine Verschiebebewegung wenigstens eines Riegels bzw. eines mindestens einen Riegel tragenden Schubglieds übertragen. Der erfindungsgemäße Antrieb weist ein Ritzel 9 und ein Zahnrad 10 auf. Das Ritzel wird vom Schließbart 4 angetrieben, und es treibt seinerseits das Zahnrad 10. Die Drehbewegung des Zahnrads 10 kann beispielsweise über eine Zahnstange in eine Hin- und Herbewegung umgesetzt werden, wobei erforderlichenfalls auch noch weitere Zahnräder zwischengeschaltet sein können. Auf den weiteren Kraftfluß kommt es aber im Zusammenhang mit der erfindungsgemäßen Ausbildung des Antriebs nicht an, vielmehr kann sie von bekannter Bauart sein.The rotary movement of the locking bar is transmitted in a suitable manner into a displacement movement of at least one bolt or of a pushing element carrying at least one bolt. The drive according to the invention has a pinion 9 and a gearwheel 10. The pinion is driven by the locking bit 4 and it in turn drives the gearwheel 10. The rotational movement of the gearwheel 10 can be converted into a back and forth movement, for example, via a toothed rack, wherein, if necessary, further gearwheels can also be interposed. The further flow of force is not important in connection with the design of the drive according to the invention, rather it can be of a known type.

Das Ritzel 9 hat die Gestalt eines radial geschlitzten Ringes. Die Breite des Schlitzes 11 entspricht etwa der Breite des flachen Gehäuseteils 2 des Schließzylinders 1, so daß der Schließzylinder bei fluchtender Zuordnung zu diesem Schlitz senkrecht zur Bildebene leicht aus dem Ritzel herausgezogen werden kann. Dies ist insofern notwendig, als der gesamte Antrieb mit Ausnahme des Schließzylinders beispielsweise in einem Schloßkasten, einer Tür od. dgl. montiert ist und man den Schließzylinder erst dann einsetzt, wenn die Tür endgültig angeschlagen ist.The pinion 9 has the shape of a radially slotted ring. The width of the slot 11 corresponds approximately to the width of the flat housing part 2 of the lock cylinder 1, so that the lock cylinder can be easily pulled out of the pinion perpendicular to the image plane when aligned with this slot. This is necessary insofar as the entire drive, with the exception of the lock cylinder, is mounted in a lock case, a door or the like, for example, and the lock cylinder is only used when the door is finally hinged.

Die maximale Dicke des ringförmigen Ritzels 9, in radialer Richtung gemessen, bestimmt sich aus dem Abstand des zylindrischen Teils des Drehglieds 7 von der Innenfläche 12 des stegförmigen Mittelteils 13 des flachen Gehäuseteils 2. In Richtung der Drehachse 14 des Drehglieds 7 gesehen, entspricht die Breite des Ritzels 9 etwa der Breite des Schtießbarts 4, und beide Breiten sind bestimmt durch die Breite des Gehäuseschlitzes 15 des SchHeßzytinders 1. Der Innendurchmesser 16 des Ritzels 9 ist wesentlich größer als der Außendurchmesser des zylindrischen Gehäuseteils 3 des Schließzylinders 1, wodurch das Ritzel 9 eine exzentrische Anordnung gegenüber der Drehachse 14 des Schließbarts 4 erhält. Die Lagerung des Ritzels erfolgt beispielsweise in einer ringförmigen Aufnahme 17 im Schloßkasten od. dgl.The maximum thickness of the ring-shaped pinion 9, measured in the radial direction, is determined from the distance of the cylindrical part of the rotary member 7 from the inner surface 12 of the web-shaped central part 13 of the flat housing part 2. When viewed in the direction of the axis of rotation 14 of the rotary member 7, the width corresponds of the pinion 9 approximately the width of the shooting bar 4, and both widths are determined by the width of the housing slot 15 of the SchHeßzytinder 1. The inner diameter 16 of the pinion 9 is much larger than the outer diameter of the cylindrical housing part 3 of the lock cylinder 1, whereby the pinion 9 one Eccentric arrangement with respect to the axis of rotation 14 of the locking bar 4 receives. The pinion is stored, for example, in an annular receptacle 17 in the lock case or the like.

Das Ritzel 9 ist in der Art eines Tellerrads ausgebildet, und es besitzt axial abstehende Zähne 18, die sich an einer der beiden Stirnseiten des Ringes 19 befinden. Das Zahnrad 10 ist, wie Fig. 2 zeigt, wesentlich dünner als das Ritzel 9, und seine Dicke entspricht vorzugsweise der Zahnhöhe der Hitzelzähne 18. Außerdem ist das Zahnrad ats stirnverzahntes Rad ausgebildet, wobei die Zahnform von Zahnrad und Ritzel in Fig. 1 deutlich zu sehen ist.The pinion 9 is designed in the manner of a ring gear and it has axially projecting teeth 18 which are located on one of the two end faces of the ring 19. The gear 10 is, as Fig. 2 shows, much thinner than the pinion 9, and its thickness preferably corresponds to the tooth height of the heat teeth 18. In addition, the gear is formed as a spur gear, the tooth shape of the gear and pinion in Fig. 1 clearly you can see.

Das Zahnrad 10 bzw. dessen Zähne 20 weisen jedoch insofern noch eine Besonderheit auf, als wenigstens einer, vorzugsweise aber zwei davon, nämlich die Zähne 21 und 22, als verkürzte Zähne ausgebildet sind. Der Grund liegt darin, daß sich im Bereich des Schlitzes 11 des Ritzels 9, zwischen den beiden diesseits und jenseits des Schlitzes angebrachten Zähnen, der als Antriebsglied wirkende Schließbart 4 befindet, der sich senkrecht zur Bildebene etwa gleich weit erstreckt wie die Zähne 18 des Ritzels 9. Dadurch ist an dieser Stelle die Zahnlücke zwischen den benachbarten Ritzelzähnen nicht zu nutzen, d. h. ein normal langer Zahn des Zahnrads kann dort nicht zwischen die beiden Ritzelzähne treten. Die Verkürzung der Zähne 21 und 22 ist jedoch nicht problematisch, weil bei diesem Antrieb nur relativ geringe Kräfte zu übertragen sind. Erforderlichenfalls wäre es jedoch ohne weiteres möglich, die Breite des Schließbarts auf die Breite des Ringes 19 zu reduzieren, so daß man auf verkürzte Zähne beim Zahnrad 10 verzichten könnte. Diese Ausbildung ist jedoch erst in zweiter Linie vorgesehen, weil man in bevorzugter Weise handelsübliche Schließzylinder verwenden können soll.The gearwheel 10 and its teeth 20, however, have a special feature in that at least one, but preferably two, namely the teeth 21 and 22, are designed as shortened teeth. The reason for this is that in the area of the slot 11 of the pinion 9, between the two teeth on both sides and beyond the slot, there is the locking bit 4, which acts as a drive member and extends perpendicularly to the image plane approximately as far as the teeth 18 of the pinion 9. As a result, the tooth gap between the adjacent pinion teeth cannot be used at this point. H. a normal long tooth of the gear cannot step between the two pinion teeth. The shortening of the teeth 21 and 22 is not problematic, however, because only relatively small forces are to be transmitted with this drive. If necessary, however, it would be readily possible to reduce the width of the locking bit to the width of the ring 19, so that one could do without shortened teeth on the gear 10. However, this training is only provided in the second place, because it should be possible to use commercially available locking cylinders in a preferred manner.
