Abstract

A reversible latch (4) for a door lock is actuated via a pull-back lever (6) which is kinematically connected to the latch shank (5) by means of a coupling (10) disengageable counter to spring force (spring 9). One version of the coupling (10) provides a driving bolt (11) which can be pressed in counter to spring force (spring leg 13) and is located in the pull-back lever (6) and which engages into a recess (15, 15') in the latch shank (5). When the driving bolt (11) is pressed back through an actuating orifice (16), the latch (4), including the latch shank (5), can then be extracted and reinserted in reverse. For this purpose, the latch shank (5) has, at its free end, run-on slopes (17) for the driving bolt (11). <IMAGE>

Description

Die Erfindung betrifft eine umstellbare Falle für ein Türschloß mit einem Stulp, durch welchen die Falle durchgreift,und mit einem an die Falle anschließenden und im Schloßgehäuse geführten Fallenschaft, in welchem ein drückerbetätigbarer, die Fallenbewegung steuernder Rückzughebel eingreift.The invention relates to a convertible latch for a door lock with a faceplate through which the latch engages, and with a latch shaft adjoining the latch and guided in the lock housing, in which a lever handle which can be actuated by the latch and which controls the latch movement engages.

Türfallen weisen eine Auflaufschräge auf, die mit einem stockseitigen Schließblech zusammenspielt. Die Anordnung der Auflaufschräge auf der linken oder der rechten Fallenseite muß auf die Schließrichtung der Tür abgestimmt sein. Um die Produktion und insbesondere die Lagerhalterung zu vereinfachen, hat man Schlösser (Einstemmschlösser) entwickelt, bei welchen die Falle dem Bedarf vor Ort, also direkt an der Baustelle, der Schließrichtung der Tür angepaßt werden kann.Door latches have a run-on slope that interacts with a striking plate on the stock side. The arrangement of the run-on slope on the left or the right side of the latch must match the direction of closing of the door. In order to simplify production and in particular the storage bracket, locks (mortise locks) have been developed in which the latch can be adapted to the closing direction of the door as required on site, i.e. directly at the construction site.

Es ist eine Konstruktion bekannt, bei der die Falle gegen die Kraft einer Feder allenfalls mit Hilfe eines Werkzeuges aus dem Schloßgehäuse über den Stulp herausziehbar und um eine zylindrische Mittelachse gegenüber dem Fallenschaft um 180° umdrehbar ist. Sobald man die Falle losläßt, springt sie zurück und die Unstellung ist vollzogen. Eine andere Ausführung weist in den Seitenwänden des Schloßgehäuses im Bereich des Fallenschaftes unmittelbar an den Stulp anschließend Ausnehmungen in der Größe der Falle auf. Die Falle kann in das Innere des Schloßgehäuses zurückgedrückt und im Bereich der Ausnehmungen um eine Mittelachse um 180° verdreht werden. Nach der Umstellung springt die Falle wieder in die Grundstellung zurück.A construction is known in which the latch can be pulled out of the lock housing over the faceplate against the force of a spring at most with the aid of a tool and can be rotated through 180 ° about a cylindrical central axis with respect to the falling shaft. As soon as you release the trap, it jumps back and the misalignment is complete. Another embodiment has recesses in the size of the latch in the side walls of the lock housing in the area of the latch shaft directly after the faceplate. The latch can be pushed back into the interior of the lock housing and rotated through 180 ° in the area of the recesses around a central axis. After the change, the trap jumps back to the basic position.

Die Erfindung zielt darauf ab, die Konstruktion sowie das Umstellen selbst zu vereinfachen. Dies wird erfindungsgemäß dadurch erreicht, daß zwischen den Rückzughebel und dem gegebenenfalls zwei parallele Schenkel aufweisenden Fallenschaft eine gegen Federkraft ausrückbare Kupplung vorgesehen ist. Wird die Kupplung ausgerückt, dann besteht keine Verbindung zwischen dem Rückzughebel und dem Fallenschaft, sodaß die Falle zusammen mit dem Fallenschaft aus dem Türschloß herausgezogen werden kann.Nach dem Einstecken der Falle mit Schaft in der gewünschten Richtung rastet die Kupplung wieder ein und die Umstellung ist vollzogen. Die Falle ist dadurch austauschbar. Sie kann an die Drückergarnitur farblich angepaßt und beispielsweise messing- oder chromfarbig gewählt werden. Auch kann die Ausschlußlänge durch Tausch der Falle der Gegebenheiten angepaßt werden. Schließlich ist es auch möglich, eine Rollfalle bei Bedarf einzusetzen. Die gegen Federkraft ausrückbare Kupplung kann im Fallenschaft vorgesehen sein und formschlüssig in den Rückzughebel oder die Nuß eingreifen bzw. an diesen angreifen oder aber in technischer Umkehr kann die Kupplung im Rückzughebel oder der Nuß eingebaut sein und mit einem Verbindungsbolzen, Mitnehmer, Haken oder einem ähnlichen Kupplungsstück in dem Fallenschaft eingreifen bzw. an diesem angreifen. Es ist zweckmäßig, wenn die ausrückbare Kupplung einen Mitnahmebolzen umfaßt, der im Rückzughebel bis zu einen Anschlag axial verschiebbar gelagert ist und in eine Ausnehmung im Fallenschaft eingreift und wenn der Mitnahmebolzen durch eine mit dem Bolzen fluchtende Betätigungsöffnung in einer Schloßplatte des Schloßgehäuses gegen Federkraft zurückdrückbar und aus dem Eingriff in dem Fallenschaft ausrückbar ist. Zum Umstellen und zur Entnahme der Falle mit dem Schaft aus dem Schloßgehäuse wird der Mitnahmebolzen durch die Öffnung in der Seitenwand, z.B. mittels eines Stiftes (Schraubendrehers) zurückgedrückt,worauf die Falle mit dem Schaft entnommen, umgedreht und wieder eingesetzt werden kann. Besonders vorteilhaft ist es, wenn der Fallenschaft bzw. die Schenkel desselben an ihren freien Enden Auflaufschrägen zum stirnseitigen Untergreifen des gegebenenfalls ballig ausgebildeten Mitnahmebolzens und zum Zurückschieben sowie zum Einrasten in die Ausnehmung des Fallenschaftes aufweist. Dadurch ist ein manuelles Betätigen der Kupplung beim Einsetzen der Falle in das Schloßgehäuse nichtmehr erforderlich.The invention aims to simplify the construction and the changeover itself. This is achieved according to the invention in that a clutch which can be disengaged against spring force is provided between the retraction lever and the drop shaft, which may have two parallel legs. If the clutch is disengaged, there is no connection between the retraction lever and the drop shaft, so that the case together with the drop shaft from the door lock After inserting the latch with the shaft in the desired direction, the coupling engages again and the change is complete. The trap is therefore interchangeable. It can be color-matched to the lever handle set and selected, for example, brass or chrome. The exclusion length can also be adjusted by changing the case. Finally, it is also possible to use a roller trap if necessary. The clutch, which can be disengaged against spring force, can be provided in the drop shaft and positively engage or engage in the retraction lever or the nut or, in a technical reversal, the clutch can be installed in the retraction lever or the nut and with a connecting bolt, driver, hook or the like Engage the coupling piece in the drop shaft or engage it. It is expedient if the disengageable clutch comprises a driving pin, which is axially displaceably mounted in the retraction lever up to a stop and engages in a recess in the drop shaft and if the driving pin can be pressed back against spring force in a lock plate of the lock housing and through an actuating opening aligned with the pin can be disengaged from the engagement in the drop shaft. To move and remove the latch with the shaft from the lock housing, the driving pin is pushed back through the opening in the side wall, for example by means of a pin (screwdriver), whereupon the latch with the shaft can be removed, turned over and reinserted. It is particularly advantageous if the falling shank or the legs thereof have run-on bevels at their free ends for gripping under the front side of the optionally spherical driving pin and for pushing back and for latching into the recess of the falling shank. As a result, manual actuation of the clutch when inserting the latch into the lock housing is no longer necessary.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt. Fig. 1 zeigt den Fallenbereich eines Einstemmschlosses im Längsschnitt, Fig. 2 einen Querschnitt nach der Linie II-II in Fig. 1, Fig. 3 einen Schnitt nach der Linie III-III in Fig. 1 und Fig. 4 einen Schnitt durch einen Teilbereich der Fig. 1 nach der Linie IV-IV, jedoch in einem Stadium des Einsetzens der Falle kurz vor dem Einrasten der Kupplung.An embodiment of the invention is shown in the drawings. Fig. 1 shows the latch area of a mortise lock in longitudinal section, Fig. 2 shows a cross section 1, FIG. 3 shows a section along line III-III in FIG. 1 and FIG. 4 shows a section through a portion of FIG. 1 along line IV-IV, but in one stage the latch is inserted shortly before the clutch engages.

In einem Schloßgehäuse, das einen Stulp 1 und seitliche Schloßplatten 2, 3 umfaßt, ist eine Falle 4 mit Fallenschaft 5 verschiehbar gelagert. Zur Verschiebung ist ein als Winkelhebel ausgebildeter Rückzughebel 6 vorgesehen, der um den Achsbolzen 7 drehbar angeordnet ist. Der Rückzughebel 6 wird einerseits über ein Hebelsystem 8 von einem Drücker betätigt. Anderseits greift der Rückzughebel 6 in den Fallenschaft 5 ein und überträgt seine Drehbewegung in eine lineare Rückzugbewegung der Falle 4. Eine Feder 9 umgibt den Achsbolzen 7 und spannt den Rückzughebel 6 im Sinne eines Ausschiebens der Falle 4 vor.In a lock housing, which comprises a faceplate 1 and side lock plates 2, 3, a latch 4 with a drop shaft 5 is mounted so that it can be slid. A retraction lever 6, which is designed as an angle lever and is rotatable about the axle pin 7, is provided for displacement. The retraction lever 6 is operated on the one hand by a lever system 8 by a pusher. On the other hand, the retraction lever 6 engages in the drop shaft 5 and transmits its rotary movement into a linear retraction movement of the latch 4. A spring 9 surrounds the axle bolt 7 and prestresses the retracting lever 6 in the sense of extending the latch 4.

Die kinematische Verbindung zwischen dem Rückzughebel 6 und dem Fallenschaft 5 erfolgt durch eine ausrückbare Kupplung 10, die einen Mitnahmebolzen 11 umfaßt, der in einer Querbohrung 12 (Stufenbohrung) des Rückzughebels 6 gegen Federkraft (Schenkel 13 der Feder 9) verschiebbar ist. Der Mitnahmebolzen 11 überragt den Rückzughebel 6 seitlich und greift in seiner durch einen Kragen 14 begrenzten Ausschubstellung (Fig. 2) in ein vertikales Langloch 15 in einem Schenkel des Fallenschaftes 5 ein. Wird der Rückzughebel 6 mittels des Drückers nach rechts (Fig. 1) verschwenkt, dann beschreibt der Mitnahmebolzen 11 einen Kreisbogen und nimmt, im Langloch 15 gleitend, den Fallenschaft 5 mit der Falle 4 mit.The kinematic connection between the retraction lever 6 and the drop shaft 5 takes place by means of a disengageable coupling 10 which comprises a driving pin 11 which can be displaced in a transverse bore 12 (stepped bore) of the retraction lever 6 against spring force (leg 13 of the spring 9). The driving pin 11 projects beyond the retraction lever 6 and engages in its extended position, delimited by a collar 14 (FIG. 2), in a vertical elongated hole 15 in one leg of the drop shaft 5. If the retraction lever 6 is pivoted to the right (FIG. 1) by means of the pusher, the driving pin 11 describes a circular arc and, sliding in the elongated hole 15, takes the falling shaft 5 with the case 4 with it.

In der Schloßplatte 3 des Schloßgehäuses ist eine Öffnung 16 vorgesehen (Fig. 2), die mit dem Mitnahmebolzen 11 in der Grundstellung nach Fig. 1 fluchtet. Soll nun die Falle 4 umgestellt werden, dann wird der Mitnahmebolzen 11 gegen die Kraft der Feder 13 bzw. 9 zurückgeschoben, bis der Mitnahmebolzen 11 aus dem Langloch 15 des Fallenschaftes 5 ausrastet. Das Zurückschieben des Mitnahmebolzens 11 erfolgt in zweckmäßiger Weise mittels eines beim Einbau eines Einstemmschlosses zwangsläufig griffbereiten Schraubendrehers. Sobald der Mitnahmebolzen 11 vom Fallenschaft 5 entkuppelt ist, kann letzterer zusammen mit der Falle 4 stulpseitig aus dem Schloßgehäuses herausgezogen werde. Nach Umdrehen wird die Falle 4 mit dem Schaft 5 wieder in die Öffnung im Stulp 1 eingeschoben (Fig. 4). Die beiden Schenkel des Fallenschaftes 5 sind stirnseitig mit je einer Auflaufschräge 17 ausgestattet. Auf diese rastet der stirnseitig vorzugsweise ballig ausgebildete Mitnahmebolzen 11 auf, wird beim weiteren Einschieben (Pfeil) der umgestellten Falle zurückgedrückt (Pfeil), bis der Mitnahmebolzen 11 in das Langloch 15' des Fallenschaftes 5 einschnappt. Dadurch ist die kinematische Verbindung zwischen dem Fallenschaft 5 und dem Rückzughebel 6 wieder hergestellt.An opening 16 is provided in the lock plate 3 of the lock housing (FIG. 2), which is aligned with the driving pin 11 in the basic position according to FIG. 1. If the trap 4 is now to be changed, then the driving pin 11 is pushed back against the force of the spring 13 or 9 until the driving pin 11 disengages from the elongated hole 15 of the falling shaft 5. The driving pin 11 is pushed back expediently by means of a screwdriver which is inevitably within reach when installing a mortise lock. As soon as the driving pin 11 is uncoupled from the drop shaft 5, the latter can be pulled out of the lock housing together with the latch 4 on the cuff side. After turning the case 4 with the shaft 5 is pushed back into the opening in the face plate 1 (Fig. 4). The two legs of the drop shaft 5 are each provided on the end face with a ramp 17. The driving pin 11, which is preferably crowned at the end, snaps onto this, the further shifted (arrow) pushes back the changed latch (arrow) until the driving pin 11 snaps into the elongated hole 15 'of the falling shaft 5. As a result, the kinematic connection between the drop shaft 5 and the retraction lever 6 is restored.

Im Ausführungsbeispiel weist der fallenschaftseitige Arm des Rückzughebels 6 einen Schlitz 18 auf, in welchem der Schenkel 13 der Feder 9 liegt. Es wird somit nur eine Feder sowohl für den Fallenausstoß als auch für die Vorspannung des Mitnahmebolzens 11 verwendet. Es kann für den Fallenausstoß jedoch eine unabhängig vom Rückzughebel 6 angeordnete Fallenfeder vorgesehen sein, die am Fallenschaft 5 angreift. Bei dieser Ausführung hätte der Mitnahmebolzen 11 eine separate Feder. Wird bei dieser Variante der Mitnahmebolzen 11 hineingedrückt, also entkuppelt, dann springt die Falle 4 mit dem Schaft 5 unter der Wirkung einer Fallenfeder selbsttätig aus dem Schloßgehäuse heraus (Ausstoßautomatik).In the exemplary embodiment, the drop shaft arm of the retraction lever 6 has a slot 18 in which the leg 13 of the spring 9 lies. Thus, only one spring is used both for the latch ejection and for the pretensioning of the driving pin 11. However, a latch spring which acts independently of the retraction lever 6 and acts on the latch shaft 5 can be provided for the latch ejection. In this embodiment, the driving pin 11 would have a separate spring. If, in this variant, the driving pin 11 is pushed in, that is to say uncoupled, the latch 4 with the shaft 5 automatically jumps out of the lock housing under the action of a latch spring (automatic ejection).

Der Rückzughebel kann auch Teil der Schloßnuß sein und somit unmittelbar mit dem Drücker in Wirkvervindung stehen. Die Schloßnuß hat dann einen Vorsprung, der analog zum Rückzughebel 6 an seinen Ende die gegen Federkraft ausrückbare Kupplung 10 trägt. Damit die Falle, etwa beim Zuschlagen einer offenen Tüp, bloß zurückweicht ohne den Drücker zu bewegen (also bei umgekehrter Aktivierung der Falle) greift der Mitnahmebolzen 11 nicht in ein Langloch 15, sondern in eine Ausnehmung, die sich auch in Richtung zur Falle erstreckt, wobei die Länge der Ausnehmung dem Fallenausschluß entspricht. Statt einer solchen Ausnehmung kann auf dem Fallenschaft 5 auch eine Ausschlagfläche, z.B. ein nasenartiger Vorsprung vorgesehen sein, an dem der Mitnahmebolzen 11 angreift. Es kann aber auch ein Freilauf zwischen dem Drücker und einer Schloßnuß eingebaut sein, sodaß der Drücker zwar die Nuß mitnimmt, in umgekehrter Richtung die Nußbewegung nicht zu einer Bewegung des Drückers führt. In technischer Umkehr kann der Mitnahmebolzen auch im Fallenschaft vorgesehen sein und-gegen Federkraft ausrückbar - in eine Ausnehmung im Rückzughebel oder in der Nuß eingreifen bzw. an einer Anlagefläche des Rückzughebles oder der Nuß angreifen.The retraction lever can also be part of the lock nut and thus be directly connected to the handle. The lock nut then has a projection which carries the clutch 10 which can be disengaged against spring force at its end analogously to the retraction lever 6. So that the trap, for example when slamming an open toe, simply withdraws without moving the pusher (i.e. when the trap is activated in reverse), the driving pin 11 does not engage in an elongated hole 15, but in one Recess, which also extends in the direction of the trap, the length of the recess corresponding to the trap exclusion. Instead of such a recess, a deflection surface, for example a nose-like projection, can also be provided on the drop shaft 5, on which the driving pin 11 engages. However, a freewheel can also be installed between the handle and a lock nut, so that the handle takes the nut with it, in the opposite direction the nut movement does not lead to a movement of the handle. In a technical reversal, the driving pin can also be provided in the falling shank and — can be disengaged against spring force — engage in a recess in the retraction lever or in the nut or engage on a contact surface of the retracting lever or the nut.
