Abstract

The lock, especially mortise lock has a bolt (17) and a latch (6) operated by a change-over lever (16) operated by a closure element (22). The change-over lever, after its swivel movement away from the closure element and as a result of a transverse displacement of the change-over element to the bolt is disconnected from the bolt. A thrust piece (30) is formed by a protuberance (31) on the lock-cover . The bolt forms a pocket (25) into which fits a carrier (26) belonging to the change-over lever.

Description

Die Erfindung betrifft ein Schloß, insbesondere Einsteckschloß, mit Riegel und wechselhebelbetätigbarer Falle, wobei der Wechselhebel zum Rückzug der Falle bei einer Öffnungsschließbetätigung schließgliedgesteuert angehoben wird, bei Riegelvorschlußbetätigung durch Angriff des Riegels am Wechselhebel vom Schließglied bis gegen einen Anschlag weggeschwenkt wird und bei Riegelrückschlußbetätigung durch Angriff des Riegels am Wechselhebel wieder zurückgeschwenkt wird, wobei der Schwenkweg infolge eines Freiganges kleiner ist als der Riegelverlagerungsweg.The invention relates to a lock, in particular mortise lock, with latch and change lever operated Trap, the change lever being used to retract the trap an opening closing operation controlled by a closing element is raised when the latch is actuated by Attack of the bolt on the change lever from the closing element until is swung away against a stop and at Dead bolt actuation by attacking the bolt on Exchange lever is pivoted back, the Swivel path is smaller than that due to an open access Bolt displacement.

Ein Schloß der in Rede stehenden Art ist bekannt aus der DE 32 13 454 A1, wobei der zweitourig vorschließbare Riegel einen Kupplungszapfen trägt, der in eine fensterförmige Öffnung des Wechselhebels eintaucht derart, daß in Bewegungsrichtung des Riegels ein Freigang von etwa der Größe einer Riegeltour besteht. Beim Vorschließen des Riegels durchläuft der Kupplungszapfen diesen Freigang innerhalb der fensterförmigen Öffnung, einhergehend mit einer Mitnahme des Wechselhebels zufolge Kantenanlage der Öffnung an dem Kupplungszapfen. Erreicht der Wechselhebel dann seine Anschlagstellung an der Rückseite des Stulpes, so verlagert sich ausschließlich bei der Vorschließbetätigung nur noch der Riegel. Im Bereich der fensterförmigen Öffnung ist der Wechselhebel, in Riegelverlagerungsrichtung gesehen, entsprechend breit zu gestalten, so daß besonders geringe Dornmaße nicht realisierbar sind.A castle of the type in question is known from DE 32 13 454 A1, the two-speed lockable Bolt carries a coupling pin that in one immersed in the window-shaped opening of the change lever such that there is free passage in the direction of movement of the bolt about the size of a bolt tour. At the The coupling pin runs through when the bolt is closed this opening inside the window-shaped opening, along with taking the change lever with you Edge contact of the opening on the coupling pin. Then the change lever reaches its stop position on the back of the cuff, so it only shifts with the pre-actuation only the Bars. In the area of the window-shaped opening is the Change lever, seen in the direction of bolt displacement, to be designed accordingly wide, so that particularly small Backset dimensions are not feasible.

Dem Gegenstand der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Schloß so auszugestalten, daß neben einer günstigen Steuerung des Wechselhebels besonders geringe Dornmaße realisierbar sind.The object of the invention is based on the object to design a generic castle so that in addition to a favorable control of the change lever particularly small backset dimensions can be realized.

Diese Aufgabe ist zunächst und im wesentlichen bei einem Schloß mit den Merkmalen des Anspruchs 1 gelöst, wobei darauf abgestellt ist, daß der Wechselhebel nach seiner weg vom Schließglied gerichteten Schwenkverlagerung als Folge einer Querverlagerung des Wechselhebels zum Riegel bei Erreichen der Anschlagstellung vom Riegel abgekuppelt wird.This task is first and foremost a lock with the features of claim 1 solved, it is based on the fact that the change lever after its swivel displacement directed away from the locking member as a result of a transverse displacement of the change lever to the bolt when the stop position of the bolt is reached is uncoupled.

Zufolge derartiger Ausgestaltung ist ein gattungsgemäßes Schloß geschaffen, welches sogar mit einem Dornmaß von 25 mm erstellt werden kann. Dies ist möglich aufgrund der besonderen Steuerung des Wechselhebels. Da eine fensterförmige Öffnung im Wechselhebel entfällt, kann der Wechselhebel im mit dem Riegel zusammenwirkenden Bereich besonders schmal ausgeführt werden, was die Reduzierung des Dornmaßes zuläßt. Möglich ist es jedoch auch, Schlösser mit Dornmaßen zu schaffen, welches Dornmaß größer ist als 25 mm. Zusätzlich zu seiner Schwenkverlagerung unterliegt der Wechselhebel nach Erreichen seiner Anschlagstellung während der Riegelvorschließbetätigung einer Querverlagerung. Diese ist dazu genutzt, den Wechselhebel vom Riegel abzukuppeln, so daß bei weiterer Schließbetätigung nur der Riegel vorschließt. Die Schwenkverlagerung des Wechselhebels braucht dabei nur so groß zu sein, daß sein mit dem Schließglied zusammenwirkendes Ende aus dem Bewegungsbereich des Schließgliedes gelangt. Da der Wechselhebel nicht durch eine fensterförmige Öffnung geschwächt wird, läßt sich dennoch bei schmaler Bauform des Wechselhebels eine stabile Ausgestaltung realisieren. Erfindungsgemäß ist dabei vorgesehen, daß der Anschlag von einem Vorsprung der Schloßdecke gebildet ist und sein Abstand zum Schließzylinder dem kleinsten Dornmaß entspricht. Werden Dornmaße größerer Abmessung gewählt, so ist entsprechend der Vorsprung der Schloßdecke zu positionieren. Zur Erzielung des besonders geringen Dornmaßes von 25 mm wird der Anschlag von der Rückseite des Stulpes gebildet. Die Steuerung des Wechselhebels durch den Riegel resultiert daraus, daß der Riegel eine Tasche ausbildet, in welche ein Mitnehmer des Wechselhebels eingreift, wobei die den Mitnehmer beim Riegelvorschluß beaufschlagende Taschenwand eine insbesondere schräge Steuerfläche ausbildet für das querverlagerte Auskuppeln des Mitnehmers aus der Tasche. Vorerst bewirkt die Steuerfläche in der ersten Vorschlußphase des Riegels eine Mitnahme des Wechselhebels bis zum Anschlag. Ist dieser erreicht und wird die Vorschließbewegung des Riegels fortgesetzt, überfährt der Mitnehmer die Steuerfläche, woraufhin der Mitnehmer die Tasche verläßt, verbunden mit einen Abkuppeln des Wechselhebels von der Riegelverlagerung. Um den Wechselhebel während des Rückschließens wieder in den Bewegungsbereich des Schließgliedes bringen zu können, beaufschlagt die der Steuerfläche gegenüberliegende Taschenwand den Mitnehmer bei der Rückschließverlagerung.
Damit der Wechselhebel beim Rückschließen zwangsläufig in seine Kuppelstellung zum Riegel gelangt, also in die Tasche eintaucht, ist ein in der Endphase des Riegelrückschlusses den Mitnehmer in die Tasche zurücksteuernder Steuervorsprung vorgesehen, welcher den Mitnehmer in der Riegelrückschlußstellung auch in der Tasche hält. Zwecks Reduzierung von Bauteilen, verbunden mit einer kostengünstigen Fertigung des Schlosses, ist der Mitnehmer ein abgewinkelter Fortsatz des Wechselhebels, der im Winkelaußenscheitel eine Steuerfläche ausbildet, die zum Einsteuern des Mitnehmers in die Tasche vom Steuervorsprung beaufschlagt wird. Die Rückschließverlagerung des Riegels kann demgemäß verhakungsfrei durchgeführt werden. Optimal erweist es sich dabei, daß der Steuervorsprung eine Schräge aufweist. Demgemäß wirken die Steuerfläche des Winkelaußenscheitels und diese Schräge zusammen, was die Einsteuerung des Mitnehmers in die Tasche optimiert. Schließlich trägt noch die Tatsache zur Kosteneinsparung bei der Fertigung des Schlosses bei, daß der Steuervorsprung bzw. der Anschlag durch in die Schloßdecke eingeprägte Sicken ausgebildet ist. Demgemäß sind zur Wechselhebelsteuerung keine zusätzlichen Bauteile erforderlich.As a result of such a configuration, a generic lock is created, which can even be created with a backset of 25 mm. This is possible due to the special control of the change lever. Since there is no window-shaped opening in the change lever, the change lever can be made particularly narrow in the area interacting with the bolt, which allows the backset to be reduced. However, it is also possible to create locks with backset, which backset is larger than 25 mm. In addition to its swivel displacement, the change lever is subject to a transverse displacement after it reaches its stop position during the bolt lock actuation. This is used to uncouple the change lever from the bolt so that only the bolt closes when the lock is actuated further. The swivel displacement of the change lever only needs to be so large that its end cooperating with the locking member comes out of the range of motion of the locking member. Since the change lever is not weakened by a window-shaped opening, a stable design can nevertheless be achieved with a narrow design of the change lever. According to the invention it is provided that the stop is formed by a projection of the lock top and its distance from the lock cylinder corresponds to the smallest backset. If backset sizes of larger dimensions are selected, the projection of the lock ceiling must be positioned accordingly. To achieve the particularly small backset of 25 mm, the stop is formed from the back of the cuff. The control of the change lever by the bolt results from the fact that the bolt forms a pocket into which a driver of the change lever engages, the pocket wall acting on the driver when the bolt is closed forming a particularly inclined control surface for the transverse displacement of the driver from the pocket. For the time being, the control surface causes the change lever to be carried as far as it will go in the first preliminary phase of the bolt. If this has been reached and the preliminary movement of the bolt is continued, the driver drives over the control surface, whereupon the driver leaves the pocket, in connection with uncoupling the change lever from the bolt displacement. In order to be able to bring the change lever back into the range of motion of the closing element during the closing, the pocket wall opposite the control surface acts on the driver during the closing shift.
So that the change lever inevitably comes into its dome position to the bolt when it is closed, i.e. it dips into the pocket, in the final phase of the bolt inference the driver returns into the pocket and provides a control projection which also holds the carrier in the pocket in the bolt return position. In order to reduce components, combined with an inexpensive manufacture of the lock, the driver is an angled extension of the change lever, which forms a control surface in the outer corner of the angle, which is acted upon by the control projection for inserting the driver into the pocket. The locking can be relocated accordingly without hooking. It turns out optimally that the control projection has a slope. Accordingly, the control surface of the angular outer apex and this slope act together, which optimizes the control of the driver in the pocket. Finally, the fact that the control projection or the stop is formed by beads embossed into the castle ceiling also contributes to the cost saving in the manufacture of the castle. Accordingly, no additional components are required for the change lever control.

The latter works with a lock cover Control projection 28 together. This is roughly bar-like designed and has a faceplate 2 facing Slant 29 on. The tax advantage is formed 28 by an embossed in the castle ceiling 5 Beading, cf. in particular FIGS. 6 to 9.

In der zurückgeschlossenen Riegelstellung unterläuft der Wechselhebel 16 den Steuervorsprung 28. Der Wechselhebel 16 erstreckt sich somit zwischen der zugekehrten Breitfläche des Riegelkopfes 17' und dem Steuervorsprung 28. Dadurch wird der Mitnehmer 26 zwangsläufig bis in die Tasche 25 gesteuert und gehalten, vergl. insbesondere Fig. 6. Der Steuervorsprung 28 erstreckt sich dabei in fluchtender Gegenüberlage zum Mitnehmer 26.Undermined in the closed bolt position the change lever 16 the control projection 28. The change lever 16 thus extends between the facing Wide area of the bolt head 17 'and the control projection 28. This makes the driver 26 inevitable controlled and held in the pocket 25, cf. 6 in particular. The control projection 28 extends in alignment with the driver 26th

Unterhalb des Steuervorsprunges 28 und dem Stulp 2 benachbart besitzt die Schloßdecke 5 einen Anschlag 30, welcher von einem Vorsprung 31 der Schloßdecke gebildet ist. Auch dieser Vorsprung ist als in die Schloßdecke 5 eingeprägte Sicke gestaltet. Der Abstand x des Anschlages 30 zur Schließzylinderachse A entspricht dabei dem kleinsten Dornmaß. Um das beim dargestellten Schloß vorhandene Dornmaß noch zu verringern, kann auf den Vorsprung 31 verzichtet werden. Dann dient als Anschlag die Rückfläche des Stulpes 2.Below the control projection 28 and the faceplate 2 adjacent the castle ceiling 5 has a stop 30, which is formed by a projection 31 of the castle ceiling is. This projection is also in the castle ceiling 5th embossed bead designed. The distance x of the stop 30 to the lock cylinder axis A corresponds to that smallest backset. To the castle shown Reducing existing backset can on Projection 31 are dispensed with. Then serves as a stop the back surface of the cuff 2.

Es stellt sich folgende Wirkungsweise ein:
Zum Zurückziehen der Falle 6 bei bereits zurückgeschlossenem Riegel 17 ist mittels des zum Schließzylinder zugehörigen Schlüssels das Schließglied 22 in Uhrzeigerrichtung zu drehen. Dabei beaufschlagt die Anschlagschulter 19 des Zahnkranzes 20 das untere Ende 18 des Wechselhebels 16. Dieser wird hierdurch angehoben, verbunden mit einem Verschwenken des Fallenangriffshebels 11 um die Drücknußachse, wobei die mit diesem gekuppelte Falle 6 schloßeinwärts gezogen wird. Die Taschenlänge ist so groß bemessen, daß das Anheben des Wechselhebels 16 und damit auch des Mitnehmers 26 nicht beeinträchtigt ist.The following mode of action occurs:
To retract the latch 6 with the bolt 17 already closed, the locking member 22 must be turned clockwise by means of the key associated with the locking cylinder. The stop shoulder 19 of the ring gear 20 acts on the lower end 18 of the change lever 16. This is raised thereby, connected with a pivoting of the latch engaging lever 11 about the nut axis, the case 6 coupled with this being pulled inward of the lock. The pocket length is dimensioned so large that the lifting of the change lever 16 and thus also the driver 26 is not impaired.

Ist das Vorschließen des Riegels 17, ausgehend von Fig. 1 und 3 erwünscht, so hat eine Schließdrehung entgegen Uhrzeigerrichtung zu erfolgen. Über den Zahnkranz 20 und das mit diesem zusammenwirkende Untersetzungsgetriebe 23 erfährt sowohl der Treibstangen-Anschlußschieber 24 als auch der Riegel 17 eine Verlagerung in Verriegelungsrichtung. In der ersten Vorschlußphase des Riegels 17 bewirkt die als schräge Steuerfläche 25''' gestaltete Taschenwand ein Verschwenken des Wechselhebels 16 um den Gelenkbolzen 14 zwischen Fallenangriffshebel 11 und Wechselhebel 16. Letzterer verläßt dabei den Bereich des Steuervorsprunges 28. Sobald der Wechselhebel 16 mit seinem unteren Ende 18 gegen den Anschlag 30 tritt, vergleiche Fig. 4 und 7, führt die als schräge Steuerfläche gestaltete Taschenwand 25''' zu einer Querverlagerung des Wechelhebels 16 verbunden damit, daß der Mitnehmer 26 die Tasche 25 verläßt. Eine Übergangsstellung ist dabei in Figur 8 veranschaulicht. Durch weitere Schließdrehung wird dann die Position gemäß Fig. 5 und 9 erreicht, in welcher der Riegel 17 vollständig vorgeschlossen ist. Der Wechselhebel 16 erstreckt sich zwischen dem Anschlag 30 und dem Steuervorsprung 28, dessen Schräge 29 dem Wechselhebel 16 zugekehrt ist. Soll der Riegel 17 zurückgeschlossen und der Treibstangenanschlußschieber 24 in die Entriegelungsstellung gebracht werden, so hat eine Schließdrehung in Uhrzeigerrichtung zu erfolgen. Aufgrund der verschwenkten Position des Wechselhebels 16 befindet sich dessen unteres Ende 18 außerhalb des Wirkungsbereiches der Anschlagschulter 19 des Zahnkranzes 20, so daß das Zurückschließen behinderungsfrei vornehmbar ist. Während dieser Rückschlußbewegung des Riegels 17 beaufschlagt die Taschenwand 25' den Mitnehmer 26 nach Durchlaufen eines entsprechenden Schließweges. Es wird dadurch der Wechselhebel 16 im Wege eines Verschwenkens mitgenommen. Hierbei treten die Steuerfläche 27 des Wechselhebels 16 und die schloßdeckenseitige Schräge 29 in Kontakt zueinander, so daß dies zu einer zwangsläufigen Querverlagerung des Wechselhebels 16 führt, dessen Mitnehmer 26 mit seinem freien Ende vollends in die Tasche 25 bis zum Taschenboden 25'' eintaucht. Nach durchgeführter Rückschließdrehung überfängt dann der Steuervorsprung 28 wieder den Wechselhebel 16 und hält ihn in seiner in Figur 4 veranschaulichten Position.Is the locking of the bolt 17, starting from Fig. 1 and 3 desired, so has a closing rotation counter Clockwise direction. Over the ring gear 20 and the reduction gear cooperating with this 23 experiences both the connecting rod connecting slide 24 and the bolt 17 a shift in the locking direction. In the first preliminary phase of the bar 17 causes the designed as an oblique control surface 25 '' ' Pocket wall a pivoting of the change lever 16 around the hinge pin 14 between the latch attack lever 11 and Change lever 16. The latter leaves the area of the control projection 28. As soon as the change lever 16 with its lower end 18 against the stop 30, compare Fig. 4 and 7, leads as an oblique control surface designed pocket wall 25 '' 'to a transverse displacement of the change lever 16 connected so that the Carrier 26 leaves the pocket 25. A transition position is illustrated in Figure 8. By more The closing rotation then becomes the position according to FIG. 5 and 9 reached, in which the bolt 17 completely is locked. The change lever 16 extends between the stop 30 and the control projection 28, whose slope 29 faces the change lever 16. If the bolt 17 is closed and the connecting rod connecting slide 24 in the unlocked position brought, it has a closing rotation clockwise to take place. Because of the swiveled Position of the change lever 16 is located there lower end 18 outside the scope of the Stop shoulder 19 of the ring gear 20, so that Locking back can be carried out without disabilities. While this return movement of the bolt 17 is applied the pocket wall 25 'the driver 26 after passing through a corresponding closing path. It will the change lever 16 by pivoting taken. Here, the control surface 27 of the Change lever 16 and the bevel 29 in contact with each other, making this an inevitable Transverse displacement of the change lever 16 leads, the Driver 26 with its free end completely in the Immerses bag 25 to the bottom of the bag 25 ''. To carried out reverse rotation then overlaps the Control projection 28 again the change lever 16 and stops him in his position illustrated in Figure 4.

Da der Freigang zwischen Riegel 17 und Wechselhebel 16 nach einem ersten Vorschließen des Riegels kein Fenster im Wechselhebel verlangt, kann der Wechselhebel sehr schmal ausgeführt werden, was die Erstellung des Schlosses mit einem geringen Dornmaß erlaubt. Reduzierbar ist das Dornmaß weiterhin, wenn auf den schloßdeckenseitigen Vorsprung 31 verzichtet wird und der dann notwendige Anschlag für den Wechselhebel 16 von der Rückseite des Stulpes 2 selbst gebildet wird.Since the clearance between bolt 17 and change lever 16th after the latch has been closed for the first time, no window in the change lever, the change lever can do a lot run narrow what the creation of the castle allowed with a small backset. Can be reduced the backset continues when on the lock cover side Projection 31 is dispensed with and the then necessary Stop for the change lever 16 from the rear of the cuff 2 itself is formed.
