Abstract

The multi-bolt lock has a latch (3) and a bolt (4) actuable by a driver (16) on the lock cylinder (17). The lock has first transmission means (23, 25) connected operatively to the bolt (4) and detente means (28) for locking the latch (3), with the bolt moved out, and thus providing additional security. In the preferred version, the lock has a coupling member (33) which acts on a slide (8) attached to the latch shank (9), and, when the lock is screwed together ready, action can be taken on this coupling member from outside through an orifice in the lock case, in order to pull out the latch (3) together with the shank (9) and reverse it through 180 DEG , in such a way that the lock can be used both for left-closing and for right-closing doors. Such a lock affords increased security and allows efficient production and installation. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf ein Schloss, insbesondere ein Mehrriegelschloss, gemäss dem Oberbegriff von Patenanspruch 1.The present invention relates to a lock, in particular a multi-bolt lock, according to the preamble of claim 1.

Solche Schlösser sind allgemein bekannt und seit langem im Verkauf. Im besonderen beschreibt die Schrift DE-A-35 04 125 ein Schloss der genannten Art. Dieses Schloss weist einen vertikalen Hebel auf, der bei Betätigung des Schlüssels zum Schliessen des Riegels abgesenkt wird und hierbei die Falle gegen Hereindrücken in den Stulp blockiert. Weiter wird dabei über einen Wechselhebel die Wirkverbindung zwischen der Nuss des Drückers und dem Schaft der Falle gelöst, so dass eine Drückerbetätigung wirkungslos ist. Beide Massnahmen dienen der Erhöhung der Einbruchsicherheit.Such locks are well known and have been on sale for a long time. In particular, the document DE-A-35 04 125 describes a lock of the type mentioned. This lock has a vertical lever which is lowered when the key is actuated to close the bolt and thereby blocks the latch from being pushed into the faceplate. Furthermore, the operative connection between the follower nut and the shaft of the latch is released via a change lever, so that actuation of the trigger is ineffective. Both measures serve to increase the security against burglary.

Aus der Schrift DE-C-845 018 ist ein weiteres Schloss bekannt, bei dem über einen Zwischenhebel und eine drehbare Scheibe die Falle blockiert wird, während die Nuss gleichzeitig frei drehbar wird. Dieses Schloss besitzt jedoch keinen separaten Riegel.Another lock is known from the document DE-C-845 018, in which the latch is blocked by means of an intermediate lever and a rotatable disc, while the nut is freely rotatable at the same time. However, this lock does not have a separate bolt.

Es ist weiter aus der Schrift DE-C-616 702 ein Schloss bekannt, bei dem die Falle auf zwei unterschiedliche Arten einsetzbar ist, so dass das Schloss wahlweise für links oder für rechts angeschlagene Türen verwendbar ist. Als Halterung für die Falle ist dabei eine Schnappverbindung vorgesehen.A lock is also known from the document DE-C-616 702, in which the latch can be used in two different ways, so that the lock can be used either for doors hinged on the left or on the right. A snap connection is provided as a holder for the trap.

Schlösser der beschriebenen Art, die im allgemeinen für Abschlusstüren im Wohnungs-, Verwaltungs- und Gewerbebau Verwendung finden, haben sich zwar in der Regel bewährt, doch hat sich einerseits das Sicherheitsbedürfnis weiter verstärkt, und andererseits der Zwang zur Rationalisierung bei der Herstellung von solchen Schlössern.Locks of the type described, which are generally used for closing doors in residential, administrative and commercial buildings, have generally proven themselves, but on the one hand the need for security has continued reinforced, and on the other hand the need for rationalization in the manufacture of such locks.

Es ist davon ausgehend die Aufgabe der Erfindung, ein Schloss der genannten Art so zu verbessern, dass allen Sicherzeitsaspekten Rechnung getragen wird. Dies bedeutet, dass Sperrmittel eingebaut sind, um bei herausgefahrenem Riegel die Falle so zu sichern, dass diese als zweiter Riegel wirkt. Weiter sollen bei ausgefahrenem Riegel die Drücker nur leer zu betätigen sein.Based on this, it is the object of the invention to improve a lock of the type mentioned in such a way that all security aspects are taken into account. This means that locking means are installed to secure the latch when the bolt is pulled out so that it acts as a second bolt. Furthermore, when the bolt is extended, the pushers should only be operated empty.

Bei einer weiteren Ausführungsform des erfindungsgemässen Schlosses soll der Schlüssel bei entriegeltem Zustand der Türe stets auf die Falle wirken. Hierneben ist es aus Rationalisierungsgründen wünschenswert, bei der Herstellung solcher Schlösser darauf zu achten, dass diese wahlweise für links oder für rechts angeschlagene Türen verwendbar sind. Eine Aufgabe der Erfindung ist es damit, ein Schloss der genannten Art mit Mitteln auszustatten, die es erlauben, aus dem fertigen Schloss die Falle herauszunehmen, um 180° zu drehen und wieder gesichert einzuführen. Hierbei sollen bereits für andere Funktionen benutzte Teile mitverwendet werden.In a further embodiment of the lock according to the invention, the key should always act on the latch when the door is unlocked. In addition, for reasons of rationalization, when manufacturing such locks it is desirable to ensure that they can be used either for doors hinged on the left or on the right. An object of the invention is therefore to equip a lock of the type mentioned with means which make it possible to remove the latch from the finished lock, to rotate it through 180 ° and to insert it again securely. Parts already used for other functions should also be used here.

Die Lösung dieser Aufgabe ist durch die Merkmale der unabhängigen Ansprüche gegeben. Die abhängigen Ansprüche geben Ausgestaltungen der Erfindung an.The solution to this problem is given by the features of the independent claims. The dependent claims provide embodiments of the invention.

Die Erfindung wird im folgenden anhand einer Zeichnung eines Ausführungsbeispiels näher erläutert, wobei in diesem Ausführungsbeispiel alle vorgenannten Funktionen und Betätigungsmöglichkeiten aufgeführt sind.

Das Schloss gemäss den Figuren 1 bis 7 ist schematisch dargestellt und es werden nur die für das Verständnis der Erfindung notwendigen Teile darin dargestellt. Figur 1 zeigt die untere Hälfte des Schlosskastens 1 mit dem Stulp 2, der Falle 3 und dem Riegel 4. Eingezeichnet ist ferner ein Drücker 5, der über eine von einer Feder 48 beaufschlagten Nuss 6 in der in Figur 1 eingezeichneten Stellung mit einer Nase 7 auf einen Schieber 8 wirkt, der am Fallenschaft 9 quer zu dessen Längsrichtung angebracht ist.The lock according to Figures 1 to 7 is shown schematically and only the parts necessary for understanding the invention are shown therein. FIG. 1 shows the lower half of the lock case 1 with the faceplate 2, the latch 3 and the bolt 4. Also shown is a pusher 5, which has a nose 7 in the position shown in FIG. 1 via a nut 6 acted upon by a spring 48 acts on a slide 8, which is attached to the drop shaft 9 transversely to the longitudinal direction.

In der in Figur 4 eingezeichneten Stellung ist ersichtlich, dass nicht nur die Nuss 6 mit ihrer Nase 7 auf den Schieber 8 wirkt, sondern auch eine an der Nuss 6 angelenkte Wippe 10 mit einer Nase 11, die auf den Schieber wirkt und die eine zweite Nase 12 aufweist, die mit einem Ende 13 eines Stössels 14 in Wirkverbindung steht, dessen anderes Ende 15 mit dem Mitnehmer 16 des Schliesszylinders 17 in Wirkverbindung steht. Der Stössel 14 ist an einem Ende mit einer Feder 18 beaufschlagt, deren anderes Ende mit einer Zuhaltung 19 verbunden ist, wodurch der Hebel zum Anliegen an einen Stift 20 gebracht wird, der auf dem Riegelschaft 21 befestigt ist. Dadurch wird Stössel 14 bei eingefahrenem Riegel gemäss den Figuren 1 oder 4 in Eingriff mit dem Mitnehmer des Schliesszylinders gebracht. Mittels den Figuren 1 und 4 ist ersichtlich, dass die Falle sowohl über den Drücker 5 als auch über den Mitnehmer des Schliesszylinders, bzw. den Schlüssel zurückgeschoben werden kann. Daraus geht jedoch auch hervor, dass zumindest der aussen an der Türe angebrachte Drücker weggelassen werden kann, da er zum Oeffnen der Türe nicht benötigt wird. Da der Drücker zumindest eine gute Handhabe bietet und in Folge seiner Uebersetzung Schaden am Schloss anrichten kann, bringt sein Weglassen erhöhte Sicherheit.In the position shown in Figure 4 it can be seen that not only the nut 6 acts with its nose 7 on the slide 8, but also a rocker 10 articulated on the nut 6 with a nose 11, which acts on the slide and the second Has nose 12 with one end 13 of a The tappet 14 is in operative connection, the other end 15 of which is in operative connection with the driver 16 of the locking cylinder 17. The plunger 14 is acted upon at one end by a spring 18, the other end of which is connected to a tumbler 19, whereby the lever is brought into contact with a pin 20 which is fastened on the locking shaft 21. As a result, plunger 14 is brought into engagement with the driver of the locking cylinder when the bolt according to FIGS. 1 or 4 is retracted. It can be seen from FIGS. 1 and 4 that the latch can be pushed back both via the pusher 5 and the driver of the locking cylinder or the key. However, this also shows that at least the handle attached to the outside of the door can be omitted, since it is not needed to open the door. Since the handle offers at least good handling and, as a result of its translation, can cause damage to the lock, its omission brings increased security.

Beim Vergleich der Figuren 1, 2 und 3 ist ersichtlich, dass beim Drehen des Mitnehmers 16 des Schliesszylinders 17 dieser am Riegelschaft 21 angreift und den Riegel 4 herausschiebt. Gleichzeitig wirkt ein Bolzen 22 auf dem Riegelschaft auf einen Schenkel einer Wippe 23, die über eine Achse 24 am Schlosskasten angelenkt ist. Das andere Ende der Wippe wirkt mit einem Bolzen 22a, der auf einer Schieberplatte 25 angebracht ist, an deren beiden Enden die Schubstangen 26 bzw. 27 für die anderen Riegel angebracht sind. Beim Herausfahren des Riegels wird gleichzeitig die Schieberplatte nach oben geschoben.When comparing FIGS. 1, 2 and 3 it can be seen that when the driver 16 of the locking cylinder 17 rotates, it engages the locking shaft 21 and pushes the locking bolt 4 out. At the same time, a bolt 22 acts on the bolt shaft on one leg of a rocker 23, which is articulated on the lock case via an axis 24. The other end of the rocker acts with a bolt 22a, which is attached to a slide plate 25, on the two ends of which the push rods 26 and 27 are attached for the other bolts. When the bolt is pulled out, the slide plate is pushed upwards at the same time.

Auf der Schieberplatte 25, zwischen der Wippe 23 und der Falle 3, sind Sperrmittel angeordnet, um bei herausgefahrenem Riegel auch die Falle zu verriegeln. Die Sperrmittel enthalten einen Sperrhebel 28, der an einem Bolzen 29 angelenkt ist, der auf der Schieberplatte 25 befestigt ist. Ausserdem ist der Sperrhebel 28 mit einer Feder 30 beaufschlagt. Der Bolzen 29 läuft ferner in einem Schieberhebel 31, der über einen am Schlosskasten befestigten Zapfen 32 an seinem anderen Ende drehbar gehalten ist.On the slide plate 25, between the rocker 23 and the latch 3, locking means are arranged to also lock the latch when the bolt is extended. The locking means include a locking lever 28 which is articulated on a bolt 29 which is fastened on the slide plate 25. In addition, the locking lever 28 is acted upon by a spring 30. The bolt 29 also runs in a slide lever 31 which is rotatably held at its other end by means of a pin 32 fastened to the lock case.

Beim Herausfahren des Riegels, bzw. Hinaufschieben der Schieberplatte 25 in die Stellung gemäss Figur 3, gelangt die Nase von Sperrhebel 28 hinter die Falle 3 und hindert diese am Zurückstossen, so dass diese die Funktion eines zusätzlichen Riegels übernimmt.When the bolt is moved out or the slide plate 25 is pushed up into the position according to FIG. 3, the nose of the locking lever 28 comes behind the latch 3 and prevents it from being pushed back, so that this takes over the function of an additional bolt.

Gleichzeitig wird über den Schieberhebel 31 eine über dem Fallenschaft angeordnete, als Kupplungsglied dienende etwa U-förmige Auslöseplatte 33 angehoben, dessen unterer Schenkel 34 auf den am Fallenschaft angeordneten Schieber 8 wirkt, um diesen ausser Eingriff mit der Nase 7 von Nuss 6 zu bringen.At the same time, an approximately U-shaped release plate 33, which is arranged above the drop shaft and serves as a coupling member, is raised via the slide lever 31, the lower leg 34 of which acts on the slide 8 arranged on the drop shaft in order to disengage it from the nose 7 of nut 6.

Gleichzeitig mit dem Verriegeln der Falle wird demnach die Nuss 6 des Drückers ausser Eingriff mit der Falle gebracht, so dass der Drücker leer dreht. Dabei ist selbstverständlich, dass bereits das Verriegeln der Falle mittels Sperrhebel 28 eine erhöhte Sicherheit gegenüber vorbekannten Konstruktionen bringt, während das gleichzeitige Leerschalten des Drückers die Sicherheit noch weiter erhöht.Simultaneously with the locking of the latch, the nut 6 of the pusher is therefore disengaged from the latch so that the pusher turns empty. It goes without saying that even locking the latch by means of the locking lever 28 brings increased security compared to previously known constructions, while the simultaneous emptying of the lever further increases the security.

In Figur 5 ist eine Situation dargestellt, in der während dem Verriegeln, etwa zwischen der Stellung gemäss den Figuren 2 und 3 der Sperrhebel nicht hinter die Falle gelangt, sondern infolge fehlerhaften Bedienung, z. B. falls beim Schliessen der Drücker nicht in der Ruhestellung ist oder wegen anderen Ursachen, an der Falle anstösst und sich dort verklemmt. Da der Sperrhebel drehbar am Bolzen 29 befestigt ist, kann der Riegel, bzw. die Schieberplatte, ungehindert ganz heraus- bzw. hinaufgefahren werden, und die übrigen Absperrfunktionen sind völlig erhalten. Desgleichen kann der Schieberhebel die Auslöseplatte 33 hochstossen und den Drücker ausser Eingriff mit der Falle bringen. Da der Sperrhebel unter der Einwirkung einer relativ starken Feder steht, genügt eine kleine Erschütterung, eventuell ein Rütteln am Drücker oder etwas ähnliches, um die Falle herauszustossen und den Sperrhebel hinter die Falle zu bringen.In Figure 5, a situation is shown in which during locking, for example between the position shown in Figures 2 and 3, the locking lever does not get behind the trap, but due to incorrect operation, for. B. if the pusher is not in the rest position when closing or because of other causes, closes the latch and jams there. Since the locking lever is rotatably attached to the bolt 29, the bolt or the slide plate can be moved out or up completely without hindrance, and the other locking functions are fully preserved. Likewise, the slide lever can push the trigger plate 33 up and disengage the trigger from the latch. Since the If the locking lever is under the influence of a relatively strong spring, a small vibration, possibly shaking the pusher or something similar, is sufficient to push the latch out and bring the locking lever behind the latch.

In den Figuren 6 und 7 sind die Mittel angegeben, die es ermöglichen, die Falle um 180° zu drehen, ohne das Schloss bzw. den Schlosskasten öffnen zu müssen. Diese Mittel, um die Falle an Ort und Stelle vor dem Einbau des Schlosses für links oder rechts angeschlagene Türen verwenden zu können, können selbstverständlicherweise auch bei vorbekannten Schlössern eingebaut werden, die nicht die vorgehend beschriebenen Merkmale bezüglich Fallensicherung und Leerlauf des Drückers bei herausgefahrenem Riegel aufweisen.FIGS. 6 and 7 show the means which make it possible to turn the latch 180 ° without having to open the lock or the lock case. These means, in order to be able to use the latch on the spot before the lock is installed for doors hinged on the left or right, can of course also be installed in previously known locks which do not have the features described above with regard to securing the latch and the lever being idle when the bolt is pulled out .

Die Auslöseplatte 33, die etwa U-förmig ausgebildet ist, weist neben dem einen Schenkel 34, der vom Schieberhebel 31 nach oben geschoben werden kann, einen zweiten Schenkel 35 auf, der von einer Feder 36 beaufschlagt ist, die am Schlosskasten angelenkt ist und sich an einer Wand des Schlosskastens abstützt. Der Abstand zwischen den beiden Schenkeln 34 und 35 entspricht der Länge des Schiebers 8, so dass in der geöffneten Stellung des Schlosses, d. h. wenn der Riegel ganz eingefahren ist, der obere Schenkel 35 durch die Feder 36 den Schieber nach unten in Eingriff mit der Nase an der Nuss bringt, wodurch die Falle 3 vor dem Herausziehen gesichert ist. Beim Verriegeln wird der untere Schenkel 34 der Auslöseplatte 33 durch den Schieberhebel angehoben, um den Schieber 8 am Fallenschaft ausser Eingriff mit der Nuss zu bringen.The trigger plate 33, which is approximately U-shaped, has in addition to the one leg 34, which can be pushed up by the slide lever 31, a second leg 35, which is acted upon by a spring 36 which is articulated on the lock case and itself supported on a wall of the lock case. The distance between the two legs 34 and 35 corresponds to the length of the slider 8, so that in the open position of the lock, i. H. when the bolt is fully retracted, the upper leg 35, by means of the spring 36, brings the slide downward into engagement with the nose on the nut, whereby the latch 3 is secured against being pulled out. When locking, the lower leg 34 of the release plate 33 is raised by the slide lever in order to bring the slide 8 out of engagement with the nut on the drop shaft.

Ausserdem wird die Falle durch einen Sicherungshebel 37 zurückgehalten, der an der Schlossplatte über eine Achse 49 angelenkt ist, und mit seiner vorderen, fallenseitigen Nase vor den Schieber 8 greift, um diesen und somit die Falle zurückzuhalten. Der Sicherungshebel ist durch eine eine Braue 50a aufweisende Herausstanzung gesichert, die in eine entsprechende Oeffnung 50 im Schlosskasten einrastet.In addition, the latch is held back by a safety lever 37 which is articulated on the lock plate via an axis 49 and which engages with the front, latch-side nose in front of the slider 8 in order to hold this and thus the latch. The locking lever is through one Brow 50a punched out secured, which snaps into a corresponding opening 50 in the lock case.

Durch den Sicherungshebel wird die Falle auch dann zurückgehalten, wenn die Nuss durch den Schieberhebel ausser Eingriff mit dem Schieber 8 gebracht wird. Soll nun die Falle umgedreht werden, muss diese soweit herausgezogen werden können, dass der Kopf 39 ganz aus dem Stulp 2 des Schlosskastens herausragt. Diese Anpassung der Falle wird bei hereingefahrenem Riegel durchgeführt, wobei, ausgehend von der Stellung gemäss Figur 1, die Nussnase im Eingriff mit dem Schieber 8 steht.The latch is also retained by the locking lever when the nut is disengaged from the slide 8 by the slide lever. If the latch is now to be turned, it must be possible to pull it out so far that the head 39 protrudes completely from the faceplate 2 of the lock case. This adjustment of the latch is carried out with the bolt retracted, the nut nose being in engagement with the slide 8, starting from the position shown in FIG. 1.

Um die Falle zu entsperren, wird, nach Hineindrücken der Braue 50a, mit einem mit 40 angedeuteten Schraubenzieher der Sicherungshebel 37, dessen eine Schenkel 53 die dafür vorgesehene Oeffnung in der Schlosskastenwand verschliesst, nach unten gedrückt, wobei die Nase 38 ausser Eingriff mit dem oberen Teil des Schiebers gelangt und anschliessend wird, wie in Figur 6 angedeutet, mit dem Schraubenzieher die Auslöseplatte 33 am oberen Schenkel 35 angehoben, um das untere Ende des Schiebers ausser Eingriff mit der Nuss zu bringen. Daraufhin stösst die Fallenfeder 41 die Falle soweit aus dem Stulp, dass der Kopf 39 daraus herausragt und die Falle um 180° gedreht werden kann, wie dies in Figur 7 angedeutet ist. Selbstverständlich muss der Stulp 2 entsprechend geformt sein, d. h. zwei Schlitze 42, bzw. 43 aufweisen, um die beiden Absätze 44 des Fallenkopfes zu führen.To unlock the latch, after pushing in the brow 50a, the securing lever 37, one leg 53 of which closes the opening provided in the lock case wall, is pressed down with a screwdriver indicated by 40, the nose 38 being disengaged from the upper one Part of the slide arrives and then, as indicated in FIG. 6, the trigger plate 33 on the upper leg 35 is raised with the screwdriver in order to disengage the lower end of the slide from the nut. The latch spring 41 then pushes the latch out of the faceplate so that the head 39 protrudes therefrom and the latch can be rotated through 180 °, as is indicated in FIG. Of course, the faceplate 2 must be shaped accordingly, i. H. have two slots 42 and 43 to guide the two shoulders 44 of the trap head.

Nach dem Umschwenken der Falle wird diese hineingestossen, bis der Schieber 8 in Eingriff mit der Nussnase und der Nase am Sicherungshebel gebracht wird, und die Ausgangsstellung gemäss Figur 1 wieder erreicht ist. Dabei geht aus Figur 4 hervor, dass der Sicherungshebel 37 noch eine weitere Funktion hat, indem der hintere Absatz der Aussparung als Anschlag für den Fallenschaft dient, wobei das hinter dem Schieber 8 gelegene Plättchen 45 zusätzlich in eine Aussparung im Schlosskasten geführt ist und dort anschlägt.After the latch has been swung over, it is pushed in until the slide 8 is brought into engagement with the nut nose and the nose on the safety lever and the starting position according to FIG. 1 is reached again. It can be seen from FIG. 4 that the securing lever 37 has a further function in that the rear shoulder of the recess serves as a stop for the falling shaft, whereby the plate 45 located behind the slide 8 is additionally guided into a recess in the lock case and strikes there.

Beim vorliegenden Schloss wurde noch einem zusätzlichen Sicherungsaspekt Rechnung getragen, indem die Schlosskastenseiten Bohrungen 46 und 47 unten, eine Mittelbohrung 51 und obere Bohrungen 52 aufweisen, um unterschiedliche, an sich bekannter und übliche Sicherheitsschilder und Sicherheitsrosetten anbringen zu können.In the present lock, an additional security aspect was taken into account by the lock case sides having bores 46 and 47 at the bottom, a central bore 51 and upper bores 52 in order to be able to attach different, known and customary security signs and security rosettes.
