Description

Die Erfindung bezieht sich auf eine Schließeinrichtung mit einem Doppelzylinder gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a locking device with a double cylinder according to the preamble of claim 1.

Normale Doppelzylinder werden von beiden Seiten mit einem Schlüssel betätigt. Damit der Zylinderkern mittels des Schlüssels drehbar wird, werden die Zuhaltungen durch die Schlüsseleinschnitte verlagert, sodaß die Trennfläche zwischen den federbelasteten Stiften im Zylindergehäuse und den Stiften im Zylinderkern mit der Mantelfläche des Zylinderkerns zusammenfällt.Normal double cylinders are operated from both sides with a key. So that the cylinder core can be rotated by means of the key, the tumblers are displaced by the key incisions, so that the separating surface between the spring-loaded pins in the cylinder housing and the pins in the cylinder core coincides with the outer surface of the cylinder core.

Bei Doppelzylindern der eingangs definierten Art ist nur ein Zylindernkern, üblicherweise der äußere, mittels eines Schlüssels in der beschriebenen Art betätigbar. Der andere Zylinderkern ist nicht mit dem umgebenden Gehäuse verriegelbar, er dient lediglich dazu, die Drehbewegung eines wahlweise mit der Hand oder mittels eines Motors betätigten Türknaufes auf die Schließnase des Türschlosses zu übertragen (vgl. W092/22720, EP-A 0 276 037).In the case of double cylinders of the type defined at the outset, only one cylinder core, usually the outer one, can be actuated by means of a key in the manner described. The other cylinder core cannot be locked with the surrounding housing, it only serves to transmit the rotary movement of a doorknob which is operated either by hand or by means of a motor to the locking lug of the door lock (see W092 / 22720, EP-A 0 276 037) .

Doppelzylinder werden derzeit in verschiedenen Ausführungen angeboten, wobei lediglich die Außenabmessungen des Zylinderkernes und des Gehäuses normiert sind. Da die zu schließenden Türen verschiedene Dicke aufweisen, muß von jeder Zylindertype eine Serie mit Zylindern verschiedener Länge auf Lager gehalten werden. Der bei den bekannten motorisch betätigten Doppelzylindern vorgesehene Austausch eines der verriegelbaren Zylinderkerne bedingt eine Verdoppelung der Lagerhaltung, obwohl elektrisch betätigbare Zylinder nur einen kleinen Anwendungsbereich und damit einen geringen Marktanteil aufweisen.Double cylinders are currently available in different versions, with only the outer dimensions of the cylinder core and the housing being standardized. Since the doors to be closed have different thicknesses, a series of cylinders of different lengths must be kept in stock for each cylinder type. The replacement of one of the lockable cylinder cores provided in the known motor-operated double cylinders requires a doubling of the Warehousing, although electrically actuated cylinders have only a small area of application and thus a small market share.

Der Erfindung liegt die Aufgabe zugrunde, den gemäß dem Stand der Technik notwendigen Umbau des elektrisch betätigten Teiles des Schlosses überflüssig zu machen.The invention has for its object to make the conversion of the electrically operated part of the lock necessary according to the prior art superfluous.

Um dies zu erreichen, wird erfindungsgemäß vorgesehen, daß der durch den Drehknauf drehbare Zylinderkern einen Verriegelungsmechanismus aufweist, welcher jenem des anderen Zylinderkerns entspricht, und daß dieser Verriegelungsmechanismus dauernd durch einen eingesteckten Schlüssel entriegelt ist, sodaß der entsprechende Zylinderkern dauernd durch die Welle des Drehknaufes betätigbar ist.To achieve this, it is provided according to the invention that the cylinder core rotatable by the rotary knob has a locking mechanism which corresponds to that of the other cylinder core, and that this locking mechanism is continuously unlocked by an inserted key, so that the corresponding cylinder core can be actuated continuously by the shaft of the rotary knob is.

Um einen herkömmlichen Doppelzylinder umzurüsten, ist gemäß der Erfindung nichts weiter nötig als eine Seite des Zylinders durch den zugehörigen Schlüssel dauerhaft zu entriegeln und den bekannten Mechanismus, beispielsweise gemäß EP-A 276 037, an dem so entriegelten Zylinderkern angreifen zu lassen. Vorzugsweise wird zur Herstellung der Verbindung zwischen Zylinderkern und Drehknauf der dauernd eingesteckte Schlüssel selbst verwendet. Um die Kupplung einfach zu gestalten, empfiehlt es sich in diesem Fall, den größten Teil des Schlüsselgriffes abzutrennen.In order to convert a conventional double cylinder, all that is necessary according to the invention is to permanently unlock one side of the cylinder using the associated key and to allow the known mechanism, for example in accordance with EP-A 276 037, to engage the cylinder core thus unlocked. The permanently inserted key is preferably used to establish the connection between the cylinder core and the rotary knob. In this case, to make the coupling simple, it is advisable to separate most of the key handle.

Die Befestigung des Türknaufes bzw. des Motors an der Türe kann auf verschiedene Weise erfolgen. Die Erfindung ermöglicht es, auch diese Maßnahme ohne Umbau der Türe oder des Türbeschlages zu verwirklichen. Der Drehknauf samt seinem gegebenenfalls vorgesehenen elektrischen oder pneumatischen Antrieb wird hiezu an einem Montageflansch gelagert, welcher beispielsweise durch Klemmen am Zylindergehäuse festgelegt wird.The door knob or the motor can be attached to the door in various ways. The invention also makes it possible to implement this measure without having to convert the door or the door fitting. For this purpose, the rotary knob, together with its electric or pneumatic drive, which may be provided, is mounted on a mounting flange, which is fixed, for example, by clamping on the cylinder housing.

Weitere Einzelheiten der Erfindung werden anschließend anhand der Zeichnung erläutert. In dieser ist Fig. 1 eine teilweise geschnittene Seitenansicht eines Ausführungsbeispieles der Erfindung, Fig. 2 ein Detail aus Fig. 1 in verschiedenen Ansichten und Fig 3 eine schaubildliche Darstellung der zur Befestigung der Antriebseinrichtung auf dem Zylindergehäuse dienenden Teile.Further details of the invention are subsequently explained with reference to the drawing. 1 is a partially sectioned side view of an exemplary embodiment of the invention, FIG. 2 shows a detail from FIG. 1 in different views, and FIG. 3 shows a diagrammatic representation of the parts used to fasten the drive device on the cylinder housing.

Wesentlich für die Erfindung ist die Verwendung eines ganz gewöhnlichen Doppelzylinders, wie es in der linken Hälfte von Fig. 1 dargestellt ist. Dieses weist ein Zylindergehäuse 12 auf, in welchem Zylinderkerne 13 und 14 gelagert sind, durch welche eine Schließnase 19 betätigt wird. Der durch die Schließnase 19 betätigte Schließmechanismus ist konstruktiv ebenfalls in üblicher Weise aufgebaut und daher nicht dargestellt. Der Zylinderkern 13 soll in üblicher Weise mittels eines Schlüssels entriegelbar und nach der Entriegelung verdrehbar sein. Die Betätigung des Zylinderkerns 14 soll hingegen über eine Drehknauf erfolgen. Dies setzt voraus, daß der Zylinderkern 14 im Zylindergehäuse 12 drehbar gemacht wird. Erfindungsgemäß wird dies dadurch erreicht, daß dauernd ein Schlüssel 11 im Zylinderkern 14 steckt und diesen entriegelt.It is essential for the invention to use an ordinary double cylinder, as shown in the left half of FIG. 1. This has a cylinder housing 12, in which cylinder cores 13 and 14 are mounted, through which a locking lug 19 is actuated. The locking mechanism actuated by the locking lug 19 is also structurally constructed in the usual way and is therefore not shown. The cylinder core 13 should be unlockable in the usual way by means of a key and rotatable after unlocking. The actuation of the cylinder core 14, on the other hand, should take place via a rotary knob. This presupposes that the cylinder core 14 is made rotatable in the cylinder housing 12. According to the invention, this is achieved by continuously inserting a key 11 into the cylinder core 14 and unlocking it.

Damit der Zylinderkern 14 verdreht werden kann, muß er mit der Welle 4 des Drehknaufs gekuppelt werden. Dies könnte grundsätzlich direkt erfolgen, bevorzugt ist jedoch ein Antrieb, welcher über den Schlüssel 11 läuft, wie dies im einzelnen weiter unten anhand von Fig. 2 dargestellt werden soll.So that the cylinder core 14 can be rotated, it must be coupled to the shaft 4 of the rotary knob. In principle, this could be done directly, but preference is given to a drive which runs via the key 11, as will be illustrated in more detail below with reference to FIG. 2.

Der Antrieb der Welle 4 des Drehknaufs erfolgt einerseits mittels des Handgriffes 9 über das Kegelrad 5 wahlweise mittels des Motors 1, der über ein Getriebe 2 das Kegelrad 6 betätigt. Die Welle 4 ist mittels Kugellagern in einem Halterahmen 3 gelagert, an welchem auch das Gehäuse von Motor 1 und Getriebe 2 befestigt ist. Die Befestigung der rechts in Fig. 1 dargestellten Betätigungseinrichtung für das Doppelzylinderschloß am Zylindergehäuse 12 erfolgt, wie anhand von Fig. 3 näher erläutert werden soll, mittels des Montageflansches 10.The shaft 4 of the rotary knob is driven on the one hand by means of the handle 9 via the bevel gear 5, optionally by means of the motor 1 which actuates the bevel gear 6 via a gear 2. The shaft 4 is supported by means of ball bearings in a holding frame 3, to which the housing of the motor 1 and transmission 2 is also fastened. The actuation device for the double cylinder lock shown on the right in FIG. 1 is attached to the cylinder housing 12, as will be explained in more detail with reference to FIG. 3, by means of the mounting flange 10.

Fig. 2 zeigt im einzelnen die Übertragung des Antriebes von der Welle 4 auf den Zylinderkern 14. Hiezu ist am Ende der Welle 4 eine Kupplungsscheibe 7 starr befestigt, welche in ihrer Mitte einen Stift 15 und nahe ihrem Umfang zwei als Anschläge 16 wirkende Zapfen trägt. Auf der Kupplungsscheibe 7 sitzt um den Stift 15 verschwenkbar ein Zwischenstück 8. Die Drehung des Zwischenstückes 8 um den Stift 15 wird durch die Anschläge 16 auf der Kupplungsscheibe 7 auf das Ausmaß der Ausnehmungen beschränkt, welche beidseits entlang des Umfanges des Zwischenstückes 8 verlaufen. Die Verbindung des Zwischenstückes 8 mit dem dauernd im Zylinderkern 14 steckenden Schlüssels 11 erfolgt über den extrem verkürzten Griffteil 18 des Schlüssels 11, welcher vom Schlitz 17 im Zwischenstück 8 aufgenommen wird. Durch die dargetellte Anordnung macht der Schlüssel 11 und damit der Zylinderkern 14 die Drehbewegung der Welle 4 mit, sobald die Anschläge 16 auf der Kupplungsscheibe 7 an der Begrenzung der Ausnehmungen anliegen, welche am Umfang des Zwischenstückes 8 vorgesehen sind. Bei einer Richtungsumkehr ist also zunächst ein Freilauf gegeben.Fig. 2 shows in detail the transmission of the drive from the shaft 4 to the cylinder core 14. For this purpose, at the end of the shaft 4, a clutch disc 7 is rigidly attached, which carries a pin 15 in the middle and near its circumference two pins 16 acting as stops . An intermediate piece 8 is pivotably seated on the clutch disc 7 about the pin 15. The rotation of the intermediate piece 8 about the pin 15 is limited by the stops 16 on the clutch disc 7 to the extent of the recesses which run along the circumference of the intermediate piece 8 on both sides. The connection of the intermediate piece 8 with the key 11 permanently inserted in the cylinder core 14 takes place via the extremely shortened grip part 18 of the key 11, which is received by the slot 17 in the intermediate piece 8. Due to the arrangement shown, the key 11 and thus the cylinder core 14 participate in the rotational movement of the shaft 4 as soon as the stops 16 on the clutch disc 7 abut the delimitation of the recesses which are provided on the circumference of the intermediate piece 8. In the event of a reversal of direction, there is initially a freewheel.

Um einen herkömmlichen Doppelzylinder in der aus Fig. 1 und 2 ersichtlichen Weise betätigen zu können, ist kein Ausbau des Zylinderkerns 14 erforderlich. Es genügt vielmehr, in diesen einen entsprechenden Schlüssel 11 einzusetzen. Auch die Befestigung der Betätigungseinrichtung (Drehknauf mit oder ohne Motor) kann, wie insbesondere aus Fig. 3 hervorgeht, ohne größere Umbaumaßnahmen erfolgen. Es ist hiezu ein Montageflansch 10 vorgesehen, welcher durch Klemmen am Zylindergehäuse 12 befestigt wird. Der Halterahmen 3 für den Drehknauf und dessen Antrieb ist fest mit dem Montageflansch 10 verbunden.In order to be able to operate a conventional double cylinder in the manner shown in FIGS. 1 and 2, it is not necessary to remove the cylinder core 14. Rather, it is sufficient to use a corresponding key 11 in this. The actuating device (rotary knob with or without a motor) can also be fastened, as can be seen in particular from FIG. 3, without major conversion measures. A mounting flange 10 is provided for this purpose, which is fastened to the cylinder housing 12 by clamping. The holding frame 3 for the rotary knob and its drive is firmly connected to the mounting flange 10.
