Abstract

The slide piece (4) is movable by a key bit or closing cylinder closure lug. The slide piece has a slot for a pin on the bolt and is held in a clamped position by a locking piece in the form of a catch (26) and catch-lug (27). The slide piece is parallel to the inverted plate (3) and is movably guided in at least two spaced-apart guides. There is a spring arrangement (36) for returning the slide piece, positioned between the slide piece and the main plate (2). When the bolt is completely returned, and the spring arrangement tensioned, a lug grips behind a catch on the spring-loaded locking lever (6). A release lever (7) corresponds to the locking lever.

Description

Die Erfindung betrifft ein Einsteckschloß mit einem im Schloßgehäuse an einem Schieber geführten Riegel, wobei der mittels eines Schlüsselbartes oder einer Schließzylinderschließnase etwa parallel zur Stulp verschiebliche Schieber einen etwa diagonal zur Stulp verlaufenden Schlitz für den Eingriff eines am Riegel angeordneten Zapfens aufweist.The invention relates to a mortise lock with a bolt guided in the lock housing on a slide, wherein the slide, which can be displaced approximately parallel to the faceplate by means of a key bit or a lock cylinder locking lug, has a slot running approximately diagonally to the faceplate for the engagement of a pin arranged on the bolt.

Die Betätigung derartiger Schlösser, d.h. die Erzielung des Riegelvorschlusses bzw. Riegelrückschlusses erfolgt sowohl manuell als auch motorisch; bei manuellem Betrieb löst der Schlüsselbart oder die Schließzylinderschließnase je nach eintouriger oder mehrtouriger Ausführung eine Verschiebebewegung des Schiebers aus, die sich entsprechend auf den Riegel überträgt. Der Verschiebeweg des Reges bzw. des Schiebers ist also abhängig von der Anzahl der Schlüsselumdrehungen. Dies wird als nachteilig empfunden.The actuation of such locks, i.e. the locking or locking back is achieved both manually and by motor; in manual operation, the key bit or the locking cylinder locking lug triggers a sliding movement of the slider, depending on the single-speed or multi-speed version, which is transferred accordingly to the bolt. The path of movement of the regulator or slide depends on the number of key turns. This is felt to be disadvantageous.

Der DE 43 37 969 A1 ist ein selbstverriegelndes Sicherheitsschloß zu entnehmen, bei dem der Riegel in der ausgefahrenen Stellung gegen Verschieben durch eine Zuhaltung im Getriebeelement gesperrt wird. Gleichzeitig ist bei einer Drückerbetätigung der ausgefahrene Riegel sowohl entsperrbar als auch einfahrbar, in der Art, daß eine Vorrichtung vorhanden ist, die den Riegel in der eingefahrenen Stellung sperrt.DE 43 37 969 A1 shows a self-locking safety lock, in which the bolt is locked in the extended position against shifting by a tumbler in the gear element. At the same time, when the handle is actuated, the extended bolt can be both unlocked and retracted, in such a way that a device is present which locks the bolt in the retracted position.

In der DE 44 07 244 C1 wird ein Verfahren zum Betätigen eines Schlosses offenbart, bei dem zum Ausschließen des Reges zwei Bedingungen vorherrschen müssen, nämlich es müssen die betroffene Tür verschlossen sein und andererseits auch die Türfalle betätigt werden. Hierdurch wird erreicht, daß der Türriegel ausschließt, wenn die betreffende Tür geöffnet ist. Gleichzeitig wird der Riegel im rückgeschlossenen Zustand nur dann in dieser Stellung gehalten, wenn die Tür auch tatsächlich geöffnet wurde.DE 44 07 244 C1 discloses a method for operating a lock, in which two conditions must prevail to exclude the rain, namely the door concerned must be closed and the door latch must also be operated. This ensures that the door latch excludes when the door in question is open. At the same time, the bolt is only held in this position in the closed state if the door has actually been opened.

In der EP 0 092 630 A1 wird die Aufgabe gelöst, ein Schloß bekannter Art so auszubilden, daß es auch mit einem Schlüssel ohne Betätigung des Drückers in eine Offenstellung gebracht werden kann. Dabei wird das Antriebsmittel als ein Kraftübertragungsmittel zwischen dem Riegel und der Treibstange so ausgebildet, daß nur in der Offenstellung des Reges eine unwirksame Kraftübertragung vorliegt; nur beim Verschieben des Reges in die Öffnungsrichtung ist somit die Kraftübertragung wirksam.EP 0 092 630 A1 solves the problem of designing a lock of a known type in such a way that it can also be brought into an open position with a key without actuating the handle. The drive means formed as a force transmission means between the bolt and the drive rod so that there is an ineffective force transmission only in the open position of the rain; the force transmission is only effective when the rain is moved in the opening direction.

Aufgabe der Erfindung ist es, sich den beim Riegelrückschluß erforderlichen Verschiebeweg des Schiebers zunutze zu machen und den Riegelvorschluß zu vereinfachen. Die Erfindung löst die gestellte Aufgabe mit der Lehre nach Anspruch 1.The object of the invention is to make use of the displacement path of the slide required for locking the bolt and to simplify the locking of the bolt. The invention solves this problem with the teaching of claim 1.

Hiernach wird der Schieber gegen die Kraft einer rückstellenden Feder beim Riegelrückschluß vorgespannt und in seiner vorgespannten Stellung gehalten. Dies kann erfindungsgemäß etwa durch eine Viertel-Drehung des Schlüssels erfolgen. Der Riegel wird dabei aus seiner voll vorgeschlossenen Position in die voll rückgeschlossene Position zurückgeführt. Dabei ist die Schließmechanik für den Riegelvorschluß gewissermaßen

Figure imgb0001
scharf gemacht".Thereafter, the slide is biased against the force of a restoring spring when the bolt is closed and held in its biased position. According to the invention, this can be done by turning the key a quarter turn. The bolt is returned from its fully closed position to the fully closed position. The locking mechanism for the bolt lock is to a certain extent
Figure imgb0001
armed ".

Nach einer weiteren etwa Viertel-Drehung des Schlüssels kann der Bart eines Schließzylinders das freie Ende eines Auslösehebels hinterfassen, der bei Beaufschlagung in entgegengesetztem Sinne nunmehr die Sperre löst, so daß der Schieber schlagartig von seiner zugeordneten Feder zurückgezogen wird und den Riegelvorschluß auslöst. Es ist ersichtlich, daß zum Auslösen des Riegelvorschlusses in Strenge gesehen nicht einmal ein eintouriges Schließen, sondern nur das Freischalten einer Sperre erforderlich ist, wobei Weniger als eine Viertel-Drehung des Schlüssels beansprucht wird.After a further approximately a quarter turn of the key, the beard of a locking cylinder can grasp the free end of a release lever which, when acted on in the opposite direction, now releases the lock, so that the slide is suddenly withdrawn from its associated spring and triggers the latch lock. It can be seen that in order to trigger the bolt lock, strictly speaking, it does not even require a one-turn locking, but only the unlocking of a lock, whereby less than a quarter turn of the key is required.

Einzelheiten der Erfindung sind durch die Merkmale der Unteransprüche gekennzeichnet.Details of the invention are characterized by the features of the subclaims.

Gemäß Anspruch 2 hat es sich als vorteilhaft erwiesen, die Spann- bzw. Auslösemechanik so auszubilden, daß zwischen dem Schieber einerseits und dem als Betätigungsglied dienenden Schlüssel- oder Schließzylinderschließnase andererseits ein Auslösehebel und ein Sperrhebel eingeschaltet sind, wobei der Auslösehebel die Sperrfunktion des Sperrhebels aufhebt.According to claim 2, it has proven to be advantageous to design the clamping or release mechanism so that between the slide on the one hand and the key or lock cylinder locking lug serving as an actuator on the other hand, a release lever and a locking lever are switched on, the release lever canceling the locking function of the locking lever .

Gemäß Anspruch 3 weist der Schieber im Bereich seines oberen freien Endes einen Federnocken für eine Feder auf; diese Feder könnte bei gleicher Wirkung sinngemäß auch im Bereich des unteren Endes des Schiebers angeordnet sein.According to claim 3, the slide in the region of its upper free end has a spring cam for a spring; with the same effect, this spring could also be arranged in the area of the lower end of the slide.

In weiterer Ausgestaltung der Erfindung ist der Sperrhebel L-förmig ausgebildet, wobei am oberen freien Ende des längeren L-Schenkels eine Rast für einen Rastnocken des Schiebers angeordnet ist. Diese Lösung hat sich als vorteilhaft erwiesen, weil durch die relativ lange Ausbildung des Schenkels günstige Hebelverhältnisse in einem Bereich geschaffen werden können, der seitlich in einem freien Raum neben der Drückernuß liegt.In a further embodiment of the invention, the locking lever is L-shaped, a catch for a catch cam of the slide being arranged at the upper free end of the longer L-leg. This solution has proven to be advantageous because, due to the relatively long design of the leg, favorable leverage ratios can be created in an area that lies laterally in a free space next to the follower.

Die Ansprüche 5 und 6 kennzeichnen vorteilhafte Merkmale des Auslösehebels.Claims 5 and 6 characterize advantageous features of the release lever.

In den Ansichten nach den Figuren 1 und 2 sind nur die für die Funktion der Erfindung zu erläuternden Bauteile dargestellt; weggelassen wurden aus Gründen der Übersichtlichkeit integrierbare Funktionen wie die Drückerbetätigung, die Wechselfunktion oder die Anti-Panik-Funktion.In the views according to FIGS. 1 and 2, only the components to be explained for the function of the invention are shown; For reasons of clarity, integrable functions such as push button actuation, the change function or the anti-panic function have been omitted.

Das Einsteckschloß 1 weist im wesentlichen ein Schloßblech 2 auf, das schließblechseitig durch eine Stulp 3 begrenzt wird. Die wesentlichen Bauteile sind der Schieber 4, der Riegel 5, der Sperrhebel 6 und der Auslösehebel 7 (siehe Figur 3 bis 5).The mortise lock 1 essentially has a lock plate 2 which is delimited by a faceplate 3 on the striking plate side. The main components are the slide 4, the bolt 5, the locking lever 6 and the release lever 7 (see Figures 3 to 5).

Wie insbesondere aus der Figur 3 erkennbar, ist im Schieber 4 ein Schlitz 14 vorgesehen, welcher etwa diagonal in einem Winkel von etwa 45° zur Stulp 3 verläuft. Der Schlitz 14 weist endseitige Raststellen 16 und 17 auf, zwischen denen an der oberen Längsseite 32 des Schlitzes 14 zusätzliche Raststellen 18 angeordnet sind. Diese zusätzlichen Raststellen 18 haben jeweils eine Gleitfläche 19 und eine Sperrfläche 20, die mit einem in Figur 1 dargestellten Zapfen 15 des Reges 5 korrespondieren.As can be seen in particular from FIG. 3, a slit 14 is provided in the slide 4, which extends approximately diagonally at an angle of approximately 45 ° to the faceplate 3. The slot 14 has locking points 16 and 17 at the ends, between which additional locking points 18 are arranged on the upper longitudinal side 32 of the slot 14. These additional locking points 18 each have a sliding surface 19 and a locking surface 20, which correspond to a pin 15 of the rain 5 shown in FIG.

Die Wirkungsweise des Einsteckschlosses 1 ist wie folgt:The action of mortise lock 1 is as follows:

In der Figur 1 ist der Riegel 5 bei vollständigem Riegelvorschluß dargestellt. Die Schließzylinderschließnase 31 liegt am Gleitstück 30 des Schiebers 4 an. Bei der Bewegung des Schlüssels in rechtsdrehendem Sinne wird der Schieber 4 in der Bildebene nach oben verschoben, wobei der Schieber 4 mit seinen Langlöchern 9 und 11 an dem am Schloßblech befestigten Zapfen 8 bzw. an der am Schloßblech befestigten Buchse 10 geführt ist. Im oberen Bereich des Schiebers 4 ist an einem Federnocken 27 (Figur 3) eine Feder 36 befestigt, die anderenends an der Buchse 10 angeschlagen ist. Die Feder 36 wird somit gespannt, wobei der Verschiebeweg so bemessen ist, daß das obere freie Ende des Schiebers 4 am Ende des Verschiebeweges mit einem Rastnocken 37 in eine Rast 26 des Sperrhebels 6 einfaßt. Der Rastnocken 37 gleitet dabei in einem Langloch 38 des Schloßbleches 2.In Figure 1, the bolt 5 is shown with complete bolt closure. The locking cylinder locking nose 31 bears against the slide 30 of the slide 4. When moving the key in a clockwise direction, the slider 4 is moved upwards in the image plane, the slider 4 with its elongated holes 9 and 11 being guided on the pin 8 fastened to the lock plate or on the socket 10 fastened to the lock plate. In the upper area of the slide 4, a spring 36 is attached to a spring cam 27 (FIG. 3), which is attached to the bush 10 at the other end. The spring 36 is thus tensioned, the displacement path being dimensioned such that the upper free end of the slide 4, at the end of the displacement path, engages with a catch cam 37 in a catch 26 of the locking lever 6. The locking cam 37 slides in an elongated hole 38 of the lock plate 2.

Während dieses Verschiebevorganges des Schiebers 4 erfolgt der Rückschluß des Riegels 5, wobei der am Riegel 5 angeordnete Zapfen 15 an der unteren Längskante 33 des Schlitzes 14 in seine endseitige rechte untere Position gleitet.During this displacement process of the slide 4, the bolt 5 is closed, the pin 15 arranged on the bolt 5 sliding on the lower longitudinal edge 33 of the slot 14 into its lower right-hand end position.

Bei einer weiteren Schwenkbewegung der Schließzylinderschließnase in der Bildebene nach rechts schwenkt die Schließzylinderschließnase gegen das untere freie Ende des Auslösehebels 7, wobei dieser gegen die Kraft der Zugfeder 39 ausschwenkt. Die Zugfeder 39 ist einerseits an einem mit dem Schloßblech verbundenen Zapfen und andererseits an einem Federnocken 28 des Auslösehebels 7 gelagert.With a further swiveling movement of the locking cylinder locking lug in the image plane to the right, the locking cylinder locking lug pivots against the lower free end of the release lever 7, which swings out against the force of the tension spring 39. The tension spring 39 is mounted on the one hand on a pin connected to the lock plate and on the other hand on a spring cam 28 of the release lever 7.

In dieser Situation ist das Einsteckschloß gewissermaßen für die Verschließtour

Figure imgb0001
scharf gemacht". Diese Situation ist in der Figur 2 dargestellt.In this situation, the mortise lock is, so to speak, for the locking tour
Figure imgb0001
armed ". This situation is shown in FIG.

Bei einer anschließenden Bewegung der Schließzylinderschließnase 31 in linksdrehendem Sinne läuft die Schließzylinderschließnase 31 gegen das untere freie Ende des Auslösehebels 7 und bewegt diesen in der Bildebene nach oben. Der Auslösehebel 7 gleitet dabei mit seinem Langloch 22 in einem mit dem Schloßblech verbundenen Zapfen 23. Bei dieser Bewegung des Auslösehebels 7 läuft die Kante 40 des Auslösehebels 7 gegen die untere Kante 41 des kurzen Schenkels 24 des Sperrhebels 6 und verschwenkt diesen um den Zapfen 42, so daß die Rast 26 den Rastnocken 37 des Schiebers 4 freigibt und der Schieber 4 schlagartig in der Bildebene nach unten schnellt. Bis zu diesem Auslösevorgang wird der Sperrhebel 6 durch eine auf der Buchse 10 angeordnete Feder 43 in seiner rechtsdrehenden Position gehalten.During a subsequent movement of the locking cylinder locking lug 31 in a counterclockwise direction, the locking cylinder locking lug 31 runs against the lower free end of the release lever 7 and moves it upward in the image plane. The release lever 7 slides with its elongated hole 22 in a pin 23 connected to the lock plate. During this movement of the release lever 7, the edge 40 of the release lever 7 runs against the lower edge 41 of the short leg 24 of the locking lever 6 and pivots it about the pin 42 , so that the detent 26 releases the detent cam 37 of the slider 4 and the slider 4 suddenly flies downward in the image plane. Up to this triggering process, the locking lever 6 is held in its clockwise rotating position by a spring 43 arranged on the bush 10.

Während der schlagartigen Abwärtsbewegung des Schiebers 4 gleitet der am Riegel 5 angeordnete Zapfen 15 von einer Endposition in die andere, d.h. er überfährt die Gleitflächen 19 der zusätzlichen Raststellen 18. Sollte der Riegel 5 jedoch am Riegelvorschluß gehindert sein, ist nur ein begrenztes Zurückdrücken des Riegels 5 bis zur Anlage an der nächstfolgenden zusätzlichen Raststelle 18 möglich; der Riegel 5 bleibt in dieser Position blockiert. Ein vollständiger Riegelrückschluß ist nur durch Betätigen des Schiebers 4 in der vorbeschriebenen Weise möglich.During the sudden downward movement of the slide 4, the pin 15 arranged on the bolt 5 slides from one end position to the other, i.e. it runs over the sliding surfaces 19 of the additional locking points 18. However, if the bolt 5 is prevented from locking the bolt, only a limited pushing back of the bolt 5 is possible until it lies against the next additional locking point 18; the latch 5 remains blocked in this position. A complete locking conclusion is only possible by operating the slide 4 in the manner described above.

Wie aus der Figur 1 ersichtlich, gleitet der Zapfen 15 des Reges 5 in einem Langloch 13 des Schloßbleches 2; ebenso weist der Auslösehebel 7 ein Langloch 12 auf, das entsprechend dem Verschiebeweg des Langloches 22 im Auge 21 des Auslösehebels 7 größer bemessen ist.As can be seen from Figure 1, the pin 15 of the rain 5 slides in an elongated hole 13 of the lock plate 2; Likewise, the release lever 7 has an elongated hole 12 which is larger in accordance with the displacement of the elongated hole 22 in the eye 21 of the release lever 7.

Die Nuß 34 bzw. die Falle 35 sind nur andeutungsweise dargestellt, ihre Funktion kann mit Bezug auf die Erfindung beliebig ausgestaltet sein.The nut 34 or the trap 35 are only indicated, their function can be designed arbitrarily with reference to the invention.
