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 einer Schließzylinderschließnase im wesentlichen parallel zur Stulp verschiebliche Schieber einem im wesentlichen diagonal zur Stulp verlaufenden Schlitz für den Eingriff eines am Riegel angeordneten Zapfens aufweist, wobei ferner der Schieber während des Riegelrückschließens von einer Feder vorgespannt und in der Riegelrückschlußposition von einer Sperre gehalten wird, derart, daß das Lösen der Sperre durch die Schließzylindernase den automatischen Riegelvorschluß auslöst.The invention relates to a mortise lock with one in the lock housing a slide led bolt, which by means of a locking cylinder locking lug Sliders which can be moved essentially parallel to the faceplate an essentially diagonal to the forend slot for the Has engagement of a pin arranged on the bolt, wherein further the Slider biased by a spring during bolt locking and is held in the latch return position by a lock, such that that the release of the lock by the lock cylinder nose the automatic Latch lock triggers.

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 Riegels bzw. des Schiebers ist also abhängig von der Anzahl der Schlüsselumdrehungen. Dies wird als nachteilig empfunden.The actuation of such locks, i.e. the achievement of the bolt advance or bolt inference takes place both manually and by motor; in manual operation, the key bit or the cylinder lock key release depending on the one-speed or multi-speed version Sliding movement of the slider, corresponding to the Bolt transmits. The movement of the bolt or slide is depending on the number of key turns. This is called felt 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 is a self-locking security lock remove, with the bolt in the extended position against Moving is locked by a tumbler in the gear element. At the same time, when the handle is pressed, the bolt is extended unlockable as well as retractable, in the 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 Riegels 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 describes a method for operating a lock discloses two conditions for excluding the bolt must prevail, namely it must lock the affected door be and on the other hand the door latch are operated. Hereby is achieved that the door latch excludes when the door in question is open. At the same time, the bolt is closed only held in this position when the door is actually opened has been.

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 Riegels eine unwirksame Kraftübertragung vorliegt; nur beim Verschieben des Riegels in die Öffnungsrichtung ist somit die Kraftübertragung wirksam.EP 0 092 630 A1 solves the problem of a lock of a known type so that it can be used with a key without actuating the Pusher can be brought into an open position. It will Drive means as a power transmission means between the bolt and the drive rod so designed that only in the open position of the bolt there is ineffective power transmission; only when moving the In the opening direction, the power transmission is effective.

Aus der WO-A-9405883 ist ein Einsteckschloß mit einem im Schloßgehäuse an einem Schieber geführten Riegel bekannt, wobei der mittels einer Schließzylindernase etwa parallel zur Stulp verschiebliche Schieber einen etwa diagonal zur Stulp verlaufenden Schlitz für den Eingriff eines am Riegel angeordneten Zapfens aufweist, wobei der Schieber mittels der Schließzylindernase beim Riegelrückschluß in der erreichten Endstellung gehalten wird, derart, daß er nach Lösen einer Sperre durch die Schließzylindernase den Riegel vorschließen kann.From WO-A-9405883 is a mortise lock with one in the lock housing on a slide led bolt known, the means of a locking cylinder lug slidable approximately parallel to the faceplate an approximately diagonal to the faceplate slot for the engagement of one has arranged on the bolt pin, the slide by means of Lock cylinder nose when dead bolt is in the end position reached is held such that it is released by a lock through the lock cylinder nose can lock the bolt.

Die FR-A-2458653 offenbart ein Schloß mit einem Riegel, welcher von einem parallel an der Stulp bewegbaren Schieber betätigt wird. Zur Vereinfachung der Schloßbetätigung wird der Schieber während des Riegelrückschließens von einer Feder vorgespannt und in einer Stellung welche mit der Riegelrückschlußposition übereinstimmt, federbeaufschlagt von einer Sperre gehalten. Eine Schloßbetätigung mittels eines Schlüssel verstellt die Sperre und löst den automatischen Riegelvorschluß aus. Das Verschieben des Schiebers erfolgt über den Drücker.FR-A-2458653 discloses a lock with a bolt which of a slide that can be moved parallel to the faceplate is operated. For simplification the lock actuation becomes the slide during the bolt closing biased by a spring and in a position which corresponds to the bolt return position, spring-loaded by held a lock. A lock operated with a key adjusts the lock and triggers the automatic bolt lock. The The slide is moved using the pusher.

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 provide the necessary in the bolt inference To take advantage of the sliding path of the slider and the bolt lock to simplify. The invention solves the problem the teaching of claim 1.

Hiernach wird der Schieber gegen die Kraft einer rückstellenden Feder beim Riegelrückschluß vorgespannt und in seiner vorgespannten Stellung gehalten, derart, daß er nach Lösen der Sperre den Riegelvorschluß auslöst. Dies kann erfindungsgemäß im wesentlichen 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 "scharf gemacht". Dies hat zur Folge, daß, wenn der Schließzylinder des Einsteckschlosses in der Riegelrückschlußposition mittels seines Schlüssels betätigt wird, der Riegel automatisch, also unabhängig von der Anzahl der Schlüsselumdrehungen ganz vorgeschlossen wird.After that, the slide against the force of a restoring spring pre-tensioned when the bolt is closed and in its pre-tensioned position kept, such that after loosening the lock, the bolt lock triggers. According to the invention, this can essentially be done by a quarter turn of the key. The bar gets full from it previous position returned to the fully closed position. The locking mechanism for the bolt lock is to a certain extent "armed". As a result, when the lock cylinder of the mortise lock in the bolt return position key is operated, the bolt is automatic, i.e. independent is completely pre-locked by the number of key turns.

Nach einer weiteren im wesentlichen 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 another essentially quarter turn of the key the beard of a locking cylinder can be the free end of a release lever leave behind, now when applied in the opposite sense the lock releases, so that the slider abruptly from its associated The spring is withdrawn and the latch lock is triggered. It it can be seen that in order to trigger the bolt lock seen in strictness not even a one-speed closing, just unlocking a lock is required, taking less than a quarter turn the key is claimed.

Es hat 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.It has proven to be advantageous to use the tensioning or triggering mechanism train that between the slide on the one hand and that as an actuator serving key or cylinder lock nose a release lever and a locking lever are turned on, wherein the release lever cancels the locking function of the locking lever.

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

Gemäß Anspruch 2 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 2, the slide has in the area of its upper free End up a spring cam for a spring; this feather could same effect in the area of the lower end of the Slider be arranged.

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, one at the upper free end of the longer L-leg Rest for a locking cam of the slider is arranged. This solution has proven to be advantageous because of the relatively long training of the leg created favorable leverage in one area can be the side in a free space next to the trigger nut lies.

Die Ansprüche 4 und 5 kennzeichnen vorteilhafte Merkmale des Auslösehebels.Claims 4 and 5 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 Drükkerbetätigung, die Wechselfunktion oder die Anti-Panik-Funktion.In the views according to Figures 1 and 2 are only those for the function components of the invention to be illustrated; were omitted functions that can be integrated for reasons of clarity, such as push-button actuation, the change function or the anti-panic function.

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 striking plate side is limited by a faceplate 3. The essential Components are the slide 4, the bolt 5, the locking lever 6 and the Release lever 7 (see Figure 3 to 5).

Wie insbesondere aus der Figur 3 erkennbar, ist im Schieber 4 ein Schlitz 14 vorgesehen, welcher im wesentlichen 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, an denen ein in Figur 1 dargestellter Zapfen 15 des Riegels 5 anliegt. As can be seen in particular from FIG. 3, there is a slot in the slide 4 14 provided which is substantially diagonal at an angle of about 45 ° to faceplate 3. The slot 14 has end stops 16 and 17, between those on the upper longitudinal side 32 of the slot 14 additional rest areas 18 are arranged. These additional Locking points 18 each have a sliding surface 19 and a blocking surface 20, against which a pin 15 of the bolt 5 shown in FIG. 1 abuts.

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 lock cylinder locking nose 31 is on the slider 30 of the Slider 4 on. Moving the key clockwise Meaning, the slider 4 is shifted upwards in the image plane the slider 4 with its elongated holes 9 and 11 on the lock plate attached pin 8 or to the socket 10 attached to the lock plate is led. In the upper area of the slide 4 is on a spring cam 27 (FIG. 3) a spring 36 is attached, the other ends to the socket 10 is struck. The spring 36 is thus tensioned, the displacement path is dimensioned so that the upper free end of the slide 4 on End of the displacement path with a locking cam 37 in a locking 26 of the Locking lever 6 borders. 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.Inference is made during this displacement process of the slide 4 of the bolt 5, wherein the pin 15 arranged on the bolt 5 the lower longitudinal edge 33 of the slot 14 in its end right lower position slides.

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 29 und andererseits an einem Federnocken 28 des Auslösehebels 7 gelagert.With a further pivoting movement of the locking cylinder locking lug in the locking cylinder locking lug swivels towards the image plane to the right the lower free end of the release lever 7, this against the Force of the tension spring 39 swings out. The tension spring 39 is on one hand connected to the lock plate pin 29 and on the other a spring cam 28 of the release lever 7 is mounted.

In dieser Situation ist das Einsteckschloß gewissermaßen für die Verschließtour "scharf gemacht". Diese Situation ist in der Figur 2 dargestellt.In this situation, the mortise lock is, so to speak, for the locking tour "armed". This situation is shown in Figure 2.

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 Sperr-hebel 6 durch eine auf der Buchse 10 angeordnete Feder 43 in seiner rechtsdrehenden Position gehalten.During a subsequent movement of the locking cylinder locking nose 31 in the left-turning sense, the locking cylinder locking nose 31 runs against the lower free end of the release lever 7 and moves it in the Image level up. The release lever 7 slides with its slot 22 in a pin 23 connected to the lock plate Movement of the trigger lever 7 runs the edge 40 of the trigger lever 7 against the lower edge 41 of the short leg 24 of the locking lever 6 and pivots this around the pin 42 so that the detent 26 the detent cam 37 releases the slide 4 and the slide 4 abruptly in the Image level soars down. Up to this triggering process the Locking lever 6 by a spring 43 arranged on the bushing 10 in its clockwise position held.

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 slides pins 15 arranged on the bolt 5 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 latch 5 is prevented from closing the latch, only one is limited pushing back of the bolt 5 until it touches the next one additional rest area 18 possible; the latch 5 remains in this Position blocked. A complete deadlock can only be reached by pressing of the slide 4 possible in the manner described above.

Wie aus der Figur 1 ersichtlich, gleitet der Zapfen 15 des Riegels 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 bolt 5 slides in one Slot 13 of the lock plate 2; the trigger lever 7 also has an elongated hole 12, which corresponds to the displacement of the elongated hole 22 is dimensioned larger 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 and the trap 35 are only hinted at, theirs Function can be designed arbitrarily with reference to the invention.

  1. A mortise lock (1) including a dead bolt (5) guided inside a lock casing at a slide lever (4), whereby said slide lever (4), essentially parallel slidably with regard to the front plate (3) by means of a closing cylinder cam (31), presents an indentation (14), which is basically diagonally oriented with regard to the front plate (3), and which is provided to catch a journal (15) arranged at the dead bolt (5), whereby during the dead bolt's retraction movement said slide lever (4) is furthermore pre-loaded by means of a spring (36) and when the dead bolt is in the retracted position, it is held by means of a bracket, such that releasing the bracket by means of the closing cylinder cam (31) triggers the automatic dead bolt extension, characterised by the following features:
    (a) the slide lever (4) is pre-loaded by means of the closing cylinder cam (31) upon the dead bolt's retraction movement,
    (b) the slide lever (4) is slidably guided, parallel with regard to the front plate (3) in at least two oblong holes (9, 11), which are spaced apart,
    (c) when the dead bolt is completely retracted and the spring (36) loaded, the slide lever (4) engages a notch (26) of a spring-loaded bracket lever (6),
    (d) when the dead bolt is in the extension position, the closing cylinder cam (31) sits close to a releasing lever (7), which is slidably basically parallel with regard to the front plate (3), and which acts upon the bracket lever (6) and releases the slide lever (4) from the notch (26).
  2. A mortise lock according to claim 1, characterised in that in the region of its upper free end the slide lever (4) presents a spring cam (27) for the spring (36).
  3. A mortise lock according to claim 1 and 2, characterised in that the bracket lever (6) is L-shape designed and the notch (26) for a catch cam (37) of the slide lever (4) is arranged at the longer L-leg's (25) upper free end.
  4. A mortise lock according to any of the claims 1 to 3, characterised in that the releasing lever (7) is guided by means of an oblong hole (22) at a journal (23) of the main lock plate (2).
  5. A mortise lock according to any of the claims 1 to 4, characterised in that, when the dead bolt moves into the extension position, edges (40, 41) abutting against each other are arranged on the one hand at the releasing lever (7) and on the other hand at the shorter leg (24) of bracket lever (6).
