Description

Die Erfindung betrifft ein Kastenschloß, dessen Riegel mittels der Zuhaltung und einem mit dieser in Eingriff stehenden Antriebselement, das von einem Drehknopf oder Zylinderschloß betätigbar ist, verschiebbar ist.The invention relates to a box lock, the bolt of which can be displaced by means of the tumbler and a drive element which engages with it and which can be actuated by a rotary knob or cylinder lock.

Es ist bei derartigen Kastenschlössern bekannt, den Riegel durch eine Zuhaltung zu verschieben, die unter der Wirkung der Mitnehmerstifte an dem Antriebselement eine Winkel- und Vorschub- bzw. Rückzugsbewegung ausführt. Um diese Bewegung zu erreichen, sind mehrere Bauteile notwendig, damit die Winkelbewegung tatsächlich in eine geradlinige Bewegung für die Betätigung des Riegels umgewandelt werden kann.With box locks of this type, it is known to move the bolt by means of a tumbler which, under the action of the driving pins on the drive element, performs an angular and feed or retraction movement. To achieve this movement, several components are necessary so that the angular movement can actually be converted into a linear movement for the actuation of the bolt.

Bei der fabrikmäßigen Montage dieser Kastenschlösser werden diese so vorbereitet, daß ein Anbringen an sog. DIN-Rechtstüren möglich ist. Soll nun die Schließrichtung geändert werden, so muß eine entsprechende Anpassung erfolgen, und dies geschieht bei den bekannten Schlössern dadurch, daß nach Lösen entsprechender Befestigungen die Zuhaltung und die diese bewegenden Teile herausgenommen, ggf. gedreht und wieder neu eingesetzt und gesichert werden. Diese Montage, die vor Ort geschieht, ist verhältnismäßig aufwendig, und es besteht u.U. auch die Gefahr, daß Teile beim Montieren verlorengehen.When these box locks are assembled at the factory, they are prepared in such a way that they can be attached to so-called DIN right doors. If the closing direction is now to be changed, an appropriate adjustment must be made, and this takes place in the known locks in that after loosening the corresponding fasteners, the tumbler and the parts moving them are removed, possibly rotated and reinserted and secured. This assembly, which takes place on site, is relatively complex, and there may be there is also the risk of parts being lost during assembly.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Kastenschloß der eingangs genannten Art so auszubilden, daß eine Anpassung an links oder rechts angeschlagene Türen schnell und ohne großen Montageaufwand durchgeführt werden kann.The invention is therefore based on the object of designing a box lock of the type mentioned in such a way that an adaptation to doors hinged on the left or right can be carried out quickly and without great assembly effort.

Gelöst wird diese Aufgabe erfindungsgemäß mit den Merkmalen im Kennzeichen des unabhängigen Anspruchs.This object is achieved according to the invention with the features in the characterizing part of the independent claim.

Der wesentliche Vorteil der erfindungsgemäßen Lösung liegt darin, daß hier praktisch nur drei Teile für die Betätigung des Riegels notwendig sind oder, genauer gesagt, außer dem Riegel und dem Antriebselement nur zwei Teile in ihrer Position zu ändern sind. Hierbei handelt es sich einerseits um die Zuhaltung, die über eine Feder-Nut-Verbindung mit dem Riegel verbunden ist, so daß auf diese Weise auf spezielle Befestigungen, die die Zuhaltung sichern, verzichtet werden kann und daß nach dem Drehen der Zuhaltung das federbelastete Druckstück ebenfalls nur auf der gegenüberliegenden Seite anzubringen ist, so daß dann das Schloß sofort angebaut werden kann.The main advantage of the solution according to the invention is that here practically only three parts are necessary for the actuation of the bolt or, more precisely, apart from the bolt and the drive element, only two parts are to be changed in their position. This is, on the one hand, the tumbler, which is connected to the bolt via a tongue and groove connection, so that special fastenings which secure the tumbler can be dispensed with and that after the tumbler has been turned, the spring-loaded pressure piece is also only to be attached on the opposite side, so that the lock can then be attached immediately.

Die Erfindung soll anhand der Zeichnungen erläutert werden, wobei in den Figuren 1-3 eine schematische Aufsicht auf die Zuhaltung mit dem Riegel in der Sperrbügelstellung und der Schließstellung sowie eine hinsichtlich der Zuhaltung abgewandelte Ausführung dargestellt sind. Der Riegel 1 wird in üblicher Weise in einer entsprechenden Parallelführung 2 des Schloßkastens verschoben. Am rückwärtigen Ende steht der Riegel 1 mit der Zuhaltung 4 über eine formschlüssige z.B. eine Feder-Nut-Verbindung 5 in Eingriff, wobei diese so ausgestaltet ist, daß eine Verschiebung oder Bewegung der Zuhaltung senkrecht zu der Verschieberichtung des Riegels möglich ist. Von dem Antriebselement sind in der Figur lediglich die beiden nebeneinander liegenden Mitnehmerzapfen 6 dargestellt.The invention will be explained with reference to the drawings, in which a schematic plan view of the tumbler with the bolt in the locking bracket position and the closed position as well as an embodiment modified with respect to the tumbler are shown in FIGS. 1-3. The bolt 1 is moved in the usual way in a corresponding parallel guide 2 of the lock case. At the rear end, the bolt 1 with the tumbler 4 is located via a form-fitting e.g. a tongue and groove connection 5 in engagement, which is designed so that a displacement or movement of the tumbler perpendicular to the direction of movement of the bolt is possible. Of the drive element, only the two adjacent driver pins 6 are shown in the figure.

Diese greifen in übliche Ausnehmungen 7 der Zuhaltung 4 ein. Für eine Anpressung der Zuhaltung an die Mitnehmerstifte 6 sorgt ein im Schloßkasten 3 verschiebbar gelagertes Druckstück 8, auf das eine Feder 9 einwirkt. Wird nun das Antriebselement gedreht, so führt die Zuhaltung 4 einerseits eine Bewegung senkrecht zu der Bewegungsrichtung des Riegels aus, gleichzeitig aber wird durch die Drehung die Zuhaltung in Bewegungsrichtung des Riegels verschoben, d.h. es tritt hier der Riegel aus dem Schloß aus, bzw. bei umgekehrter Drehung wird er in das Schloß zurückgezogen, um damit eine Tür zu schließen bzw. freizugeben.These engage in the usual recesses 7 of the tumbler 4. A pressure piece 8, which is displaceably mounted in the lock case 3 and on which a spring 9 acts, ensures that the tumbler is pressed against the driving pins 6. If the drive element is now rotated, the tumbler 4 on the one hand executes a movement perpendicular to the direction of movement of the bolt, but at the same time the tumbler is displaced in the direction of movement of the bolt, i.e. here the bolt comes out of the lock, or if it is turned in the opposite direction, it is pulled back into the lock in order to close or release a door.

Dargestellt ist in der Figur die Ausführung für eine sog. DIN-rechte Tür. Soll nun die in der Figur gezeigte Schließrichtung geändert werden, so ist es lediglich notwendig, die Zuhaltung und den Riegel herauszunehmen, um 180° zu drehen, das Druckstück 8 auf der gegenüberliegenden Seite einzusetzen und die Zuhaltung mit dem Riegel wieder in Position zu bringen. Weitere Änderungen sind nicht erforderlich.The figure shows the design for a so-called DIN right door. If the closing direction shown in the figure is now to be changed, it is only necessary to remove the tumbler and the bolt, to turn it by 180 °, to insert the pressure piece 8 on the opposite side and to bring the tumbler back into position with the bolt. No further changes are necessary.

Es sei noch darauf hingewiesen, daß die Zuhaltung 4 an einer zur Feder-Nut-Verbindung 5 senkrecht liegenden Längsseite eine wellenartige Steuerbahn 10 aufweist, die eine rastermäßige Verschiebung der Zuhaltung sichert, und zwar sind die Raststellungen erreicht bei vollständig eingeschlossenem bzw. ausgeschlossenem Riegel 1 und in einer Zwischenstellung, in der der Riegel mit einem nur angedeuteten Sperrbügel 12 in Eingriff steht, so daß die Tür in bekannter Weise nur um einen Spalt geöffnet werden kann.It should also be pointed out that the tumbler 4 has a wave-like control track 10 on a longitudinal side perpendicular to the tongue and groove connection 5, which ensures a grid-like displacement of the tumbler, namely the latching positions are reached when the bolt 1 is fully enclosed or excluded and in an intermediate position, in which the bolt engages with a locking bracket 12, which is only indicated, so that the door can only be opened by a gap in a known manner.

Um diese Raststellungen sichtbar zu machen, ist eine vom Riegel zwangsgeführte, drehbare Farbscheibe 11 vorgesehen, deren Farbkennung durch ein Fenster 15 im Schloßkasten von außen sichtbar ist. Die Steuerung der Scheibe kann z.B. durch eine Nut 13 im Riegel und einen Mitnehmerstift 14 an der Farbscheibe 11 erfolgen. Um auch für diese Farbscheibe 11 die Raststellungen zu sichern, ist - einstückig angeformt - ein Federelement 18 vorgesehen, das mit einem Anschlag 19 im Schloßkasten 3 zusammenwirkt.In order to make these locking positions visible, a rotatable colored disk 11, which is positively guided by the bolt, is provided, the color identification of which is visible from the outside through a window 15 in the lock case. The control of the disc can e.g. through a groove 13 in the bolt and a driving pin 14 on the color disk 11. In order to secure the latching positions for this colored disk 11 as well, a spring element 18 is provided, which is formed in one piece and cooperates with a stop 19 in the lock case 3.

In der Figur 3 ist eine abgewandelte Ausführung dargestellt, und zwar für ein Kastenschloß mit Schließzylinder, wobei in der Figur hier auch nur die Mitnehmerstifte 6 angedeutet sind. Bei dieser Ausführung besteht die Zuhaltung aus einer relativ dünnen oder flachen Metallplatte 16, die über ein Zwischenstück 17 mit dem Riegel verbunden ist. Das Zwischenstück 17 weist wiederum eine formschlüssige Verbindung z.B. Feder-Nut-Verbindung zum Riegel auf, während die Zuhaltung mit dem Zwischenstück form- und kraftschlüssig verbunden ist.FIG. 3 shows a modified embodiment, specifically for a case lock with a lock cylinder, only the driver pins 6 being indicated in the figure here. In this embodiment, the tumbler consists of a relatively thin or flat metal plate 16, which is connected to the bolt via an intermediate piece 17. The intermediate piece 17 in turn has a positive connection e.g. Tongue and groove connection to the bolt, while the tumbler is positively and non-positively connected to the intermediate piece.

Da die Zuhaltung relativ dünn bzw. flach ist, kann eine zur Mittelebene des Riegels exzentrische Anordnung erfolgen, d.h. das Zwischenstück ist so ausgebildet, daß die Zuhaltung aufgelegt wird und dann etwa in der Ebene einer Flachseite des Riegels liegt. Auf diese Weise könnte der Schließzylinder weiter als bisher üblich in den Schloßkasten hinein verlegt werden, so daß er nach außen nur wenige mm übersteht.Since the tumbler is relatively thin or flat, an eccentric arrangement to the central plane of the bolt can take place, ie the intermediate piece is designed so that the tumbler is placed and then lies approximately in the plane of a flat side of the bolt. In this way, the lock cylinder further than usual in the lock case so that it protrudes only a few mm to the outside.

Der Wechsel der Schließrichtung erfolgt durch einfaches Umlegen des Zwischenstückes 17, der Zuhaltung 16 und des Druckstückes 8.The changing of the closing direction takes place by simply turning over the intermediate piece 17, the tumbler 16 and the pressure piece 8.
