Abstract

The lock is particularly of the mortise type, having a stop lever actuated by a button protruding from the surface, stopping the catch from turning backwards when pressed inwards. The lever moves into the free position when the catch is pulled back under the action of an arm on the knob, and also on changing over into the release position. A free passage (F1, F2) is formed on pulling the catch back. The passage is formed between the knob arm (24) and the catch (18), and also between the latter and the changeover lever. There can be a chain link (58) between the knob arm to the middle part (50) of the section (44) of changeover lever. This has a coupling formed by a pin working in a slot (60), so that movement is possible with the knob arm stationary. The stop lever (35) can be movable by this part of the two-part change-over lever, the latter having an extension (51) engaging with the catch behind its head (19).

Description

Die Erfindung betrifft ein Türschloß, insbesondere Einsteckschloß, mit Falle und Riegel und einem mittels eines vor die Stulpfläche ragenden Tasters derart verlagerbaren Sperrhebel, daß dieser in schloßeinwärtsverlagerter Stellung die Falle gegen Rückdrücken sperrt, welcher Sperrhebel sich bei der Rückzugsbetätigung der Falle durch den Arm einer Drückernuß und auch bei Wechselbetätigung in die Freigabestellung verlagert, und mit einem bei der Rückzugsbewegung der Falle auftretenden, dieser zugeordneten Freigang, welcher zwischen Nußarm und Falle bzw. zwischen dieser und dem zweigeteilten Wechselhebel liegt, wobei der bei Drückerbetätigung mitgeschleppte, fallenseitige Wechselhebel-Abschnitt eine Steuerkurve besitzt zur Aussteuerung des Sperrhebels.The invention relates to a door lock, in particular Mortise lock, with latch and bolt and a means of a push-button protruding in front of the faceplate Locking lever that this in relocated Position the latch locks against back pressure, which locking lever is in the withdrawal actuation of the Trap by the arm of a trigger nut and also when changing the switch shifted to the release position, and with one that occurs during the retraction movement of the trap, this assigned clearance, which is between the nut arm and trap or between this and the two-part Change lever is, which is when the handle is pressed entrained, latch-side change lever section has a control cam to control the locking lever.

Ein Türschloß der in Rede stehenden Art ist bekannt aus der EP-A-0 378 124, wobei bei Wechselhebelbetätigung über den fallenseitigen Wechselhebel-Abschnitt kontinuierlich der Sperrhebel mitgenommen wird, und zwar auch dann, wenn der Wechselhebel-Abschnitt an der Falle angreift. Dies ist schließtechnisch ungünstig, da an dem zum Schließzylinder zugehörigen, relativ schwach bemessenen Schlüssel erhebliche Kräfte wirksam werden.A door lock of the type in question is known from EP-A-0 378 124, wherein when changing lever actuation continuously over the latch-side change lever section the locking lever is taken, and indeed then when the change lever section engages the trap. This is unfavorable in terms of locking technology because of the belonging to the locking cylinder, relatively weakly dimensioned Key significant forces take effect.

Dem Gegenstand der Erfindung liegt daher die Aufgabe zugrunde, ein Türschloß der in Rede stehenden Art in herstellungstechnisch einfacher Weise von schließtechnisch günstigerem Aufbau zu schaffen.The object of the invention is therefore the object based on a door lock of the type in question in Technically simple way of locking technology to create a cheaper structure.

Gelöst wird diese Aufgabe bei einem gattungsgemäßen Türschloß dadurch, daß die Steuerkurve einen konzentrisch zur Lagerstelle des fallenseitigen Wechselhebel-Abschnittes verlaufenden Bogenschlitz-Randkantenabschnitt ausbildet zum Zusammenwirken mit dem Steuerzapfen des Sperrhebels.This task is solved with a generic Door lock in that the control cam is concentric to the bearing point of the latch-side change lever section trending arch slit edge section trains to interact with the control pin the locking lever.

Zufolge derartiger Ausgestaltung ist ein gattungsgemäßes Türschloß von schließtechnisch günstigem Aufbau angegeben. Mit dem Zuziehen der Tür wird der Taster schloßeinwärts bewegt verbunden damit, daß der Sperrhebel in die Blockierungsstellung zur Falle tritt. Eine Fallenrückzugsverlagerung, sei es durch Nuß- oder Wechselhebel-Betätigung, führt dazu, daß die Steuerkurve in der ersten Phase der Verlagerung des fallenseitigen Wechselhebel-Abschnittes ausschließlich den Sperrhebel außer Eingriff zur Falle bringt. In der folgenden Phase der Wechselhebel-Betätigung taucht der Steuerzapfen in den ein Maul ausbildenden Bogenschlitz ein und stützt sich an dem betreffenden Bogenschlitz-Randkantenabschnitt ab. Da dieser konzentrisch zur Lagestelle des Wechselhebel-Abschnittes verläuft, verbleibt der Sperrhebel nach seiner Aussteuerung in einer genau definierten Stellung. Er verschwenkt weder vor noch zurück, so daß die auf den fallenseitigen Wechselhebel-Abschnitt einwirkenden, vom Schlüssel aufgebrachten Schließkräfte weitgehend zum Zurückziehen der Falle genutzt werden können. Erst bei Zurückführen des Nußarmes bzw. bei Beendigung der Wechselbetätigung verläßt der Steuerzapfen den Bogenschlitz-Randkantenabschnitt, so daß die Schloßeingerichtteile dann wieder ihre Ausgangsstellung einnehmen.As a result of such a configuration is a generic Door lock of a construction that is favorable in terms of locking technology. When the door is closed, the button is moved inwards moves connected to the fact that the locking lever in the Blocking position falls. A trap retreat shift, be it by nut or change lever actuation, causes the control curve in the first Phase of relocation of the latch-side change lever section only the locking lever out of engagement traps. In the following phase of changing lever operation the control pin dips into its mouth training arch slot and is based on the relevant arc slot edge section. There this concentric to the position of the change lever section runs, the locking lever remains after it Control in a precisely defined position. He pivots neither back nor forth, so that the on the latch-side change lever section acting from Key forces applied largely to Withdrawal of the trap can be used. Only at; only when Return the nut arm or at the end of the change operation the control pin leaves the edge of the arc slot edge section, so that the lock fittings then return to their starting position.

Eine vorteilhafte Weiterbildung besteht darin, daß der fallenseitige Wechselhebel-Abschnitt unterhalb des Taster-Verschiebeweges gelagert ist. Aufgrund dieser Ausbildung lassen sich große Hebelarme verwirklichen, die ein erleichtertes Zurückziehen der Falle und Aussteuern des Sperrhebels zulassen. An advantageous further development is that the latch-side change lever section below the push button displacement is stored. Based on these Training, large lever arms can be realized, which makes it easier to retract the trap and steer of the locking lever.

Als baulich einfache Maßnahme erweist sich die Tatsache, daß der Tasterschwanz an der fallenseitigen Schmalkante eine Blattfeder zur Steuerung des Sperrhebels entgegen Federwirkung in die Sperrstellung besitzt. Gegen die Kraft dieser Blattfeder ist dann der seine Blockierungsstellung einnehmende Sperrhebel zu verlagern, und zwar mittels der Steuerkurve des fallenseitigen Wechselhebel-Abschnittes. Die Kraft der Blattfeder ist größer als diejenige der den Sperrhebel in die Freigabestellung belastenden Feder, so daß die Blattfeder beim Zurückschieben des Tasters den Sperrhebel bestimmungsgemäß in die Blockierungsstellung bringt.As a structurally simple measure, the fact that that the stylus tail on the trap-side narrow edge a leaf spring to control the locking lever Has spring action in the locked position. Against the force of this leaf spring is then his To move the locking lever to the blocking position, by means of the control curve of the trap side Exchange lever section. The power of the leaf spring is larger than that of the locking lever in the release position loading spring so that the leaf spring when pushing the button back the locking lever as intended in the blocking position.

Eine Doppelfunktion der Sperrhebelfeder resultiert daraus, daß die Sperrhebelfeder gleichzeitig die Tasterfeder darstellt. Durch diese wird der Taster in die Freigabestellung bewegt. Letzteres geschieht beim Öffnen der Tür.A double function of the locking lever spring results from that the locking lever spring also the key spring represents. This pushes the button into the release position emotional. The latter happens when you open the Door.

Schließlich ist noch hervorzuheben, eine vom Nußarm zum Mittelbereich des fallenseitigen Wechselhebel-Abschnittes reichende Kettenlasche vorzusehen, die zufolge einer Schlitz/Zapfenverbindung gegenüber dem stillstehenden Nußarm verlagerbar ist. Die Wechselhebelbetätigung ist daher unabhängig von der Drückernuß. Es wird bei der Wechselhebelbetätigung der Wechselhebel-Abschnitt verlagert, der den Sperrhebel aus seiner Blockierungsstellung zur Falle auslöst und der nach Durchlaufen seines Freiganges die Falle zurückzieht. Die Rückzugsverlagerung mittels des Nüßarmes wird über die Schlitz/Zapfenverbindung auf den Wechselhebel-Abschnitt übertragen, so daß dieser ebenfalls verschwenkt. Einhergehend wird mit dieser Betätigung die Freigabestellung des die Falle blockierenden Sperrhebels herbeigeführt. Finally, it should be emphasized, one from the nut arm to the Middle area of the latch-side change lever section to provide sufficient chain link, according to one Slot / pin connection compared to the stationary Nut arm is shiftable. The change lever operation is therefore independent of the trigger nut. It will be at the Change lever actuation the change lever section is shifted, the locking lever out of its locked position triggers the trap and that after going through its passage pulls the trap back. The relocation by means of the nut arm over the slot / pin connection transferred to the change lever section so that this also panned. It is accompanied by this actuation the release position of the trap blocking locking lever brought about.

The latter is below the push button displacement stored near the follower nut 25. A bearing pin on the bottom of the castle serves as bearing 45. The lower area of this latch-side change lever section 44 is approximately triangular. The a triangle vertex is penetrated by the bearing stud 45. The other deep triangular apex has a bore 46 into which the upper end 47 of the bolt-side change lever section 43 is immersed. In the area of the transom cover, the transom side forms Section 43 an approximately transverse to the bolt movement directed slot 48 from the engagement of a bolt tail side Driving pin 49. The triangular Area of the tail-tail change lever section 44 continues into a central area 50. The latter extends approximately between stylus tail 30 and trap tail 21. Closes the central region 50 behind the trap head 19 on the trap tail 21 attacking operating portion 51 of a pocket 52 of the trap tail 21 reaches through. In the pocket 52 protrudes a cam 53 to attack the operating portion 51. In the starting position the Cam 53 at a distance from the actuating section 51 below Realization of an access F2, compare the basic position of the change lever 42 in FIGS. 3 and 4.

An seiner der Drückernuß 25 zugekehrten Flanke formt der Mittelbereich 50 des fallenseitigen Wechselhebel-Abschnitts 44 eine Steuerkurve 54, welche einen zu dieser Seite hin offenen Bogenschlitz-Randkantenabschnitt 55 in Form eines Maules ausbildet. Die Randkanten desselben verlaufen konzentrisch zur Lagerstelle 45, also des Anlenkpunktes des fallenseitigen Wechselhebel-Abschnitts 44. Die Steuerkurve 54 wirkt zusammen mit einem Steuerzapfen 56 des Sperrhebels 35. Dieser Steuerzapfen 56 befindet sich unterhalb des Lagerzapfens 36 für den Sperrhebel 35.On its flank facing the follower 25, the Middle region 50 of the latch-side change lever section 44 a control curve 54, which one to this Side open arch slot edge portion 55 in Shape of a mouth. The edges of the same run concentrically to bearing 45, that is Hinge point of the latch-side change lever section 44. The control cam 54 acts together with a control pin 56 of the locking lever 35. This control pin 56 is located below the journal 36 for the Lock lever 35.

Der Mittelbereich 50 trägt einen Kupplungszapfen 57, der in das eine Ende einer Kettenlasche 58 formschlüssig eintaucht. Die Kettenlasche 58 übergreift den Sperrhebel 35 und reicht bis zum Nußarm 24. Ein an diesem befestigter Zapfen 59 taucht in einen Schlitz 60 der Kettenlasche 58 ein und erstreckt sich in Grundstellung an dem einen Ende 60' des Schlitzes 60, vergleiche Figur 3 und 4.The central region 50 carries a coupling pin 57 which in one end of a link plate 58 form-fitting immersed. The chain link 58 engages over the locking lever 35 and extends to the nut arm 24. An attached to this Pin 59 dips into a slot 60 of the link plate 58 and extends in the basic position on the one end 60 'of the slot 60, see Figure 3 and 4th

Der vorgenannte Schlitz 60 dient auch zum Durchtritt des schloßbodenseitigen Zapfens 36, welcher jedoch keine Wirkverbindung mit der Kettenlasche 58 eingeht.The aforementioned slot 60 also serves for the passage of the lock base-side pin 36, which, however, none Active connection with the link plate 58 is received.

Es stellt sich folgende Wirkungsweise ein:
Wird eine mit einem erfindungsgemäß gestalteten Türschloß versehene Tür zugezogen, so beaufschlagen sowohl der Fallenkopf 19 als auch der Tasterkopf 29 ein Schließblech 62. In der Schließstellung der Tür durchgreift der Fallenkopf 19 nach vorherigem federnden Ausweichen eine Schließausnehmung 61 des Schließbleches 62, während der Tasterkopf 29 sich mit seiner Stirnfläche am türrahmenseitigen Schließblech 62 abstützt, vergleiche Figur 4. Der Taster 28 befindet sich demgemäß in schloßeinwärts verlagerter Stellung. Die an der Schmalkante des Tasterschwanzes 30 vorgesehene, in Abspreizstellung zu dieser Kante stehende Blattfeder 33 beaufschlagt die Unterkante des Sperrhebels 35 und verschwenkt diesen entgegen seiner Federbelastung verbunden damit, daß der Sperrvorsprung 40 in die Ausnehmung 41 des Fallenschwanzes 41 eintaucht. Die Sperrkante 40' liegt demgemäß dicht hinter der vertikal verlaufenden Stufe 41' der Ausnehmung 41. Eine Rückverlagerung der Falle 18 ist somit gesperrt. Es kann nun in der üblichen Weise der Riegel 8 vorgeschlossen und bei Bedarf auch wieder zurückgeschlossen werden. The following mode of action occurs:
If a door provided with a door lock designed in accordance with the invention is closed, both the latch head 19 and the push button head 29 act on a striking plate 62. In the closed position of the door, the latch head 19 passes through a closing recess 61 of the striking plate 62 after prior resilient evasion, while the push button head 29 is supported with its end face on the striking plate 62 on the door frame, compare FIG. 4. The pushbutton 28 is accordingly in the position shifted towards the lock. The leaf spring 33 provided on the narrow edge of the probe tail 30 and in the spread-apart position from this edge acts on the lower edge of the locking lever 35 and pivots it against its spring load in such a way that the locking projection 40 plunges into the recess 41 of the latch tail 41. The locking edge 40 'is accordingly closely behind the vertically extending step 41' of the recess 41. A relocation of the latch 18 is thus blocked. The bolt 8 can now be pre-closed in the usual manner and closed again if necessary.

Vom Türinneren her ist die Falle durch Drückerbetätigung zurückziehbar. Hierzu ist, ausgehend von Figur 4, die Drückernuß 25 mittels des nicht veranschaulichten Drükkers in Uhrzeigerrichtung zu bewegen. In der ersten Schwenkphase durchläuft der Nußarm 24 den zwischen diesem und der Mitnahmerkante 27 des Fallenschwanzes 21 befindlichen Freigang F1. Einhergehend nimmt der Zapfen 59 durch Beaufschlagen des Endes 60' des Schlitzes 60 die Kettenlasche 58 mit. Diese in Kupplungseingriff mit dem Mittelbereich 50 stehende Kettenlasche 58 verschenkt den fallenseitigen Wechselhebel-Abschnitt 44 um die Lagerstelle 45. Dabei beaufschlagt der oberhalb des Bogenschlitz-Randkantenabschnittes 55 liegende, geradlinige Abschnitt der Steuerkurve 54 den Steuerzapfen 56 des Sperrhebels 35, woraufhin dieser gegen die Kraft der Blattfeder 33 entgegen Uhrzeigerrichtung verschwenkt. Der Sperrvorsprung 40 desselben verläßt die Ausnehmung 41 des Fallenschwanzes 21, vergleiche Figur 5. Durch weitere Verlagerung der Drückernuß 25 in Uhrzeigerrichtung kann daher störungsfrei über den Nußarm 24 die Falle 18 vollständig zurückgezogen werden, wobei sie die Schließausnehmung 61 des Schließbleches 62 verläßt. In der zurückgezogenen Stellung der Falle 18 ist der Steuerzapfen 56 vollständig in den Bogenschlitz-Randkantenabschnitt 55 der Steuerkurve 54 eingetreten und gestattet somit das störungsfreie Verschenken des fallenseitigen Wechselhebel-Abschnittes 44. Nach Öffnen der Tür und Loslassen des Drückers kehren sowohl die Falle 18 als auch der Taster 28 federbeaufschlagt in ihre Grundstellung gemäß Figur 3 zurück.From the inside of the door is the latch by pushing the button retractable. Starting from FIG. 4, the Handle nut 25 by means of the handle, not shown to move clockwise. In the first The pivot arm 24 passes through the nut arm between the latter and the driving edge 27 of the trap tail 21 Access F1. Along with this, the pin 59 by applying the end 60 'of the slot 60 die Chain link 58 with. This in clutch engagement with the Middle region 50 standing chain link 58 gives away the latch-side change lever section 44 around the bearing point 45. It acts on the edge of the slit edge section 55 lying, straight lines Section of the control cam 54 the control pin 56 of the Locking lever 35, whereupon this against the force of Leaf spring 33 pivoted counterclockwise. The locking projection 40 of the same leaves the recess 41 of the tail 21, compare Figure 5. By further shift of the follower nut 25 clockwise can therefore be trouble-free via the nut arm 24 Trap 18 are completely withdrawn, taking the Closing recess 61 of the striking plate 62 leaves. In the retracted position of the trap 18 is the control pin 56 completely into the arch slot edge portion 55 of the control curve 54 occurred and allowed thus the trouble-free giving away of the trap side Change lever section 44. After opening the door and Letting go of the trigger both trap 18 and the pushbutton 28 is spring-loaded into its basic position back according to FIG. 3.

Das Öffnen der Tür vom Türäußeren her verlangt den Einsatz des vorschriftsmäßigen Schlüssels. Dieser ist in den Schließzylinder 17 einzuführen. Durch Schließbetätigung kann dann der Schließbart 16 gedreht werden, daß er dabei das untere Ende des riegelseitigen Wechselhebel-Abschnitts 43 des Wechselhebels 42 beaufschlagt, vergleiche Figur 7. Der riegelseitige Wechselhebel-Abschnitt 43 fährt demgemäß in Aufwärtsrichtung und verschwenkt dabei den fallenseitigen Wechselhebel-Abschnitt 44 in Uhrzeigerrichtung. In der Anfangsphase des Verschwenkens des fallenseitigen Wechselhebel-Abschnittes 44 durchläuft dessen Betätigungsabschnitt 51 den Freigang F2. Währenddessen beaufschlagt die Steuerkurve 54 mit ihrem geradlinigen Bereich den Steuerzapfen 56 des Sperrhebels 35 und verschwenkt diesen entgegen Uhrzeigerrichtung und entgegen der Kraft der tasterseitigen Blattfeder 33 vergleiche Figur 7. Einhergehend mit dem Verschwenken des fallenseitigen Abschnitts Wechselhebel-44 verlagert sich die Kettenlasche 58. Dies ist möglich wegen der Schlitz/Zapfenverbindung zwischen Kettenlasche 58 und Nußarm 24, so daß sich die Kettenlasche 58 zum stillstehenden Nußarm 24 bewegt. Mit weiterer Aufwärtsverlagerung des riegelseitigen Wechselhebel-Abschnitts 43 verschenkt der fallenseitige Wechselhebel-Abschnitt 44 weiter in Uhrzeigerrichtung, bei welchem Vorgang dann der Steuerzapfen 56 des Sperrhebels 35 in den Bogenschlitz-Randkantenabschnitt 55 eintaucht. Nach Öffnen der Tür und Zurückdrehen des Schlüssels in die Abzugsstellung geht der Wechselhebel 42 in seine Ausgangsstellung zurück. Ferner kehren sowohl die Falle 18 als auch der Taster 28 federbeaufschlagt in die Grundstellung zurück.Opening the door from the outside of the door requires effort the correct key. This is in to insert the lock cylinder 17. By closing operation the lock bit 16 can then be rotated so that it the lower end of the bolt-side change lever section 43 applied to the change lever 42, compare Figure 7. The bolt-side change lever section 43 moves accordingly in the upward direction and pivots the latch-side change lever section 44 in the clockwise direction. In the initial phase of pivoting the latch-side change lever section 44 passes through whose actuating section 51 has the clearance F2. Meanwhile acts on the control curve 54 with its straight line Area the control pin 56 of the locking lever 35 and pivots this counterclockwise and counterclockwise compare the force of the button-side leaf spring 33 Figure 7. Along with the pivoting of the trap side Section change lever-44 shifts the link plate 58. This is possible because of the Slot / pin connection between link plate 58 and Nut arm 24, so that the link plate 58 to stand still Nut arm 24 moves. With further upward shift of the bolt-side change lever section 43 is given away the latch-side change lever section 44 further clockwise, which process then the control pin 56 of the locking lever 35 in the sheet slot edge portion 55 dips. After opening the door and turn the key back to the trigger position the change lever 42 goes into its initial position back. Furthermore, both the trap 18 and the button 28 spring-loaded into the basic position back.
