Description

Die Erfindung betrifft ein Türschloß mit verschiebbarem Riegel und Falle, wobei die Falle einen Fallenstift aufweist, der in einer Fallenführung verschiebbar geführt ist, wobei der Riegel mit einem Sperrmechanismus für die Falle verbunden ist, und der Sperrmechanismus eine vom Riegel verschiebbare Fallenkulisse umfaßt, die ein Sperrelement (24) aufweist, das in Sperrstellung im Verschiebeweg der Falle oder des Fallenstiftes angeordnet ist, wodurch die Falle verriegelt ist.The invention relates to a door lock with a movable bolt and latch, the latch having a latch pin which is guided displaceably in a latch guide, the latch being connected to a locking mechanism for the latch, and the locking mechanism comprising a latch slide which is displaceable by the latch and which comprises a Has locking element (24) which is arranged in the locked position in the displacement of the trap or the trap pin, whereby the trap is locked.

Derartige Türschlösser sind überwiegend Einstemmschlösser, die die Verriegelung zwischen Türblatt und Türstock bewirken, nachdem sie durch entsprechende eingesetzte Schlösser, wie zB. Zylinderschlösser betätigt worden sind.Such door locks are mainly mortise locks, which bring about the locking between the door leaf and door frame, after having been used by appropriate locks, such as. Cylinder locks have been operated.

Herkömmliche Türschlösser der eingangs genannten Art weisen eine vom Türdrücker betätigte Falle und einen vom Schloß verschiebbaren Riegel auf. Falle und Riegel sind voneinander unabhängig betätigt. Die Falle wird nur vom Türdrücker betätigt und der Riegel nur vom zugehörigen Schloß, bzw. Schlüssel.Conventional door locks of the type mentioned have a latch operated by the door handle and a bolt that can be moved by the lock. The latch and bolt are operated independently of each other. The latch is only operated by the lever handle and the bolt only by the associated lock or key.

Die herkömmlichen Türschlösser weisen Nachteile auf. So ist es wünschenswert, die Verriegelung nicht nur über den Riegel, sondern auch über die Falle vorzunehmen. Dabei soll die Konstruktion möglichst einfach und stabil sein. Die Falle soll leicht von links auf rechts umstellbar sein. Nach Verriegelung der Falle soll diese Verriegelung über den Drückerdorn nicht spürbar sein, d.h. daß der Drückerdorn trotz der Verriegelung der Falle nach unten drückbar sein soll. Ein eventueller Einbrecher kann somit nicht die Tatsache einer Fallenverriegelung erkennen, wodurch seine Arbeit erschwert wird.The conventional door locks have disadvantages. So it is desirable not only to lock the latch, but also the latch. The construction should be as simple and stable as possible. The trap should be easy to change from left to right. After the latch has been locked, this locking should not be noticeable via the trigger pin, i.e. that the trigger mandrel should be able to be pressed down despite the latch being locked. A possible burglar cannot recognize the fact that the latch is locked, which makes his work more difficult.

Zum Stande der Technik soll auch auf die AT-PS 357 431 hingewiesen werden, die allerdings nicht die Verriegelung der Falle, sondern lediglich eine Verriegelung der Nuß offenbart.The state of the art should also refer to AT-PS 357 431 be pointed out, which, however, does not disclose the locking of the trap, but only a locking of the nut.

Fernerhin ist durch die DE-OS 36 25 541 ein Türschloß bekannt geworden, das einem ähnlichen Zweck dient und bei dem die Falle einen Mitnehmer trägt, der als schwenkbarer Haken ausgebildet ist. Ein solcher schwenkbarer Haken kann jedoch bei der erfindungsgemäßen Falle mit einem Fallenstift nicht angeordnet werden.Furthermore, a door lock has become known from DE-OS 36 25 541, which serves a similar purpose and in which the case carries a driver which is designed as a pivotable hook. However, such a swiveling hook cannot be arranged with a trap pin in the case of the invention.

Das erfindungsgemäße Türschloß ist in erster Linie dadurch gekennzeichnet, daß die Fallenführung in Richtung der Fallenverschiebung an der Fallenkulisse verschiebbar angeordnet ist (Hinterschneidung) und daß die Fallenführung weiters in Richtung der Verschiebung der Fallenkulisse verschiebbar und mit dieser verbunden ist.The door lock according to the invention is primarily characterized in that the latch guide is arranged displaceably in the direction of the latch displacement on the latch link (undercut) and that the latch guide is also displaceable in the direction of the displacement of the latch link and is connected to it.

Weitere vorteilhafte Merkamale der Erfindung sind den anhängenden Patentansprüchen der nachfolgenden Beschreibung und den Zeichnungen zu entnehmen.Further advantageous features of the invention can be found in the appended claims, the description below and the drawings.

Im nachstehenden wird die Erfindung an Hand eines Ausfürungsbeispieles gemäß den Fig. 1 und 2 näher beschrieben. Fig. 1 ist eine schematische Seitenansicht eines erfindungsgemäßen Türschlosses mit abgenommenem Deckel. Fig. 2 ist ein Schnitt nach der Linie II - II in Fig. 1 durch ein Bauteil des Türschlosses. Beide Figuren enthalten nur jene Teile, die für die Beschreibung der gegenständlichen Erfindung und deren Funktionsweise wesentlich sind.The invention is described in more detail below with reference to an exemplary embodiment according to FIGS. 1 and 2. Fig. 1 is a schematic side view of a door lock according to the invention with the cover removed. Fig. 2 is a section along the line II - II in Fig. 1 through a component of the door lock. Both figures contain only those parts that are essential for the description of the present invention and its operation.

Das dargestellte Einstemmschloß weist wie üblich einen Stulp 1 und einen Schloßkasten 2 auf, wobei der Deckel des Schloßkastens 2 abgenommen ist.The mortise lock shown has, as usual, a faceplate 1 and a lock case 2, the cover of the lock case 2 being removed.

Im Schloßkasten 2 ist der Riegel 3 verschiebbar in Richtung des Pfeiles 4 gelagert. Mit 5 ist die Ausnehmung für ein hier nicht weiter dargestelltes Zylinderschloß bezeichnet, dessen Schließnase in bekannter Weise mit den Riegelausnehmungen 6, 7 zusammenwirkt. Die Riegelausnehmung 6 sperrt bei der ersten Umdrehung und die Riegelausnehmung 7 bei der zweiten Umdrehung des Schlüssels.In the lock case 2, the bolt 3 is slidably mounted in the direction of arrow 4. 5 with the recess for a cylinder lock, not shown here, the locking lug cooperates in a known manner with the bolt recesses 6, 7. The locking recess 6 locks during the first rotation and the locking recess 7 during the second rotation of the key.

Oberhalb des Riegels 3 sitzt die Falle 8, die gegen die Kraft der Fallenfeder 9 in den Schloßkasten verschiebbar ist. Über den Fallenstift 10 ist die Falle 8 auf eine weiter unten näher beschriebene Weise mit der Nuß 11 verbunden. In den Vierkantausnehmung 12 sitzt der hier nicht dargestellte Drückerdorn, bei dessen Verdrehung in Richtung 13 gegen die Kraft der Nußfeder 14 und gegen die Kraft der Feder 9 die Falle 8 zurückgeschoben wird. Der Fallenstift und die Feder 9 stützen sich am Fallenstiftlager 15 ab. Die Nuß 11 greift mit ihrem Dorn 16 an einen Anschlag der Fallenführung 17 an.Above the bolt 3 sits the latch 8, which is displaceable against the force of the latch spring 9 in the lock case. The latch 8 is connected to the nut 11 in a manner described in more detail below via the latch pin 10. In the square recess 12 sits the trigger mandrel, not shown here, when it is rotated in the direction 13 against the force of the nut spring 14 and against the force of the spring 9, the latch 8 is pushed back. The trap pin and the spring 9 are supported on the trap pin bearing 15. The nut 11 engages with its mandrel 16 on a stop of the latch guide 17.

Die Fallenführung 17 weist einen Querschnitt auf, wie er in Fig. 2 dargestellt ist. Die Fallenführung ist verschiebbar in einer Hinterschneidung 18 der Fallenkulisse 19 angeordnet. Weiters erstreckt sich die Fallenkulisse 19 entlang der Rückwand des Schloßkastens nach unten in Richtung zum Riegel 3. Im Bereich des Riegels 3 weist die Fallenkulisse 19 eine Erweiterung 20 auf, an deren Unterkante ein schräg nach oben führender Schlitz 21 vorgesehen ist. Bei der in Fig. 1 dargestellten Stellung, bei der der Riegel zur Gänze im Schloßkasten aufgenommen ist ( Offenstellung), liegt ein mit dem Riegel verbundener Bolzen 22 innerhalb des Schlitzes 21.The latch guide 17 has a cross section as shown in FIG. 2. The latch guide is slidably arranged in an undercut 18 of the latch link 19. Furthermore, the latch link 19 extends downward along the rear wall of the lock case in the direction of the bolt 3. In the region of the bolt 3, the latch link 19 has an extension 20, on the lower edge of which a slit 21 leading obliquely upward is provided. In the position shown in FIG. 1, in which the bolt is received entirely in the lock case (open position), a bolt 22 connected to the bolt lies within the slot 21.

Die Wirkungsweise des beschriebenen Türschlosses ist folgende:
Bei Betätigung des Zylinderschlosses 5 wird der Riegel um eine Tour nach links verschoben. Dabei wird auch der zugehörige Bolzen 22 nach links verschoben, sodaß die Fallenkulisse 19 nach oben ausweichen muß. Nach Ende der esten Tour nimmt der Bolzen eine Stellung ein, wie er in Fig. 1 mit 22′ strichliert dargestellt ist. Die Anschlagkante 23 der Erweiterung 20 der Fallenkulisse 19 sitzt auf dem Bolzen 22′ auf.The operation of the door lock described is as follows:
When the cylinder lock 5 is actuated, the bolt is moved one tour to the left. The associated bolt 22 is also shifted to the left, so that the latch link 19 must dodge upwards. After the end of the first tour, the bolt assumes a position as shown in broken lines in FIG. 1 with 22 '. The stop edge 23 of the extension 20 of the latch link 19 sits on the bolt 22 '.

Zufolge der Verschiebung der Fallenkulisse 19 nach oben verschiebt sich auch der mit der Kulisse verbundene Sperrstift 24 nach oben, sodaß er dem Fallenstift 10 gegenüberliegt, wie dies strichliert eingezeichnet ist. Dabei blockiert der Sperrstift 24 die Falle 8.As a result of the displacement of the latch link 19 upwards, the locking pin 24 connected to the link also moves upward, so that it lies opposite the latch pin 10, as is shown in broken lines. The locking pin 24 blocks the trap 8.

Mit dem Hochschieben der Fallenkulisse 19 wird weiters auch die Fallenführung 17 nach oben geschoben ( bzw. gezogen ), sodaß der Dorn 16 der Nuß 11 mit dem zugehörigen Anschlag außer Eingriff kommt. Dadurch ist ein Verdrehen der Nuß 11 möglich, ohne die Falle 8 zu betätigen, die durch den Sperrstift 24 blockiert ist.When the latch link 19 is pushed up, the latch guide 17 is also pushed up (or pulled), so that the mandrel 16 of the nut 11 disengages from the associated stop. This allows the nut 11 to be rotated without actuating the latch 8, which is blocked by the locking pin 24.

Wie in Fig. 2 zu sehen ist, ist die Fallenführung 17 im wesentlichen U-förmig und nimmt zwischen ihren Schenkeln 26, 27 den Fallenstift 10 auf. Der eine Schenkel 26 ist etwas kürzer als der andere Schenkel 27. Der Anschlag für den Dorn 16 wird durch den kürzeren Schenkel 26 gebildet.As can be seen in FIG. 2, the latch guide 17 is essentially U-shaped and receives the latch pin 10 between its legs 26, 27. One leg 26 is somewhat shorter than the other leg 27. The stop for the mandrel 16 is formed by the shorter leg 26.

Die längere Ausführung des Schenkels 27 hat den Zweck, die Führung des Fallenstiftes auch in hochgeschobener Lager der Fallenführung zu gewährleisten und den Angriff des Fallenstiftes mit seinem Kopf 28 an der Fallenführung sicherzustellen.The longer version of the leg 27 has the purpose of ensuring the guiding of the trap pin even in the pushed-up bearing of the trap guide and ensuring the attack of the trap pin with its head 28 on the trap guide.

Die Umstellung der Falle 8 von links auf rechts ist einfach dadurch gelöst, daß die Falle 8 gegen den Zug der Feder 9 oder einer anderen hier nicht dargestellten Feder nach außen außerhalb der Stulp 1 gezogen, gedreht und dann wieder in die Führung der Stulp 1 eingelassen werden kann.The conversion of the trap 8 from left to right is simply achieved in that the trap 8 is pulled outwards against the pull of the spring 9 or another spring, not shown here, outside the face plate 1, rotated and then let in again in the guide of the face plate 1 can be.

Bei Verdrehung des Zylinderschlosses um eine weitere Tour tritt keine Veränderung der zuvor beschriebenen Lage der Schloßbestandteile ein. Der Riegel ist wohl ein Stück weiter nach links geschoben ( strichliert 22˝), durch den geraden Verlauf der Anschlagkante 23 erfolgt jedoch keine Veränderung der Lage der Fallenkulisse 19.If the cylinder lock is rotated by another tour, there is no change in the position of the lock components described above. The bolt is pushed a bit further to the left (dashed line 22˝), but the straight course of the stop edge 23 does not change the position of the latch link 19.

Durch Einstellung der Länge des Sperrstiftes 24 kann für die freie Beweglichkeit der Falle 8 ein gewisses Spiel eingestellt werden.By adjusting the length of the locking pin 24, a certain play can be set for the free mobility of the trap 8.

Die Bewegung der Falle 8 über die Nuß 11 und den hier nicht dargestellten Türdrücker erfolgt wie üblich, wenn der Riegel 3 nicht gesperrt ist. Der Dorn 16 schlägt am Schenkel 26 der Fallenführung 17 an und verschiebt die Fallenführung an der Hinterschneidung 18 der Fallenkulisse 19 nach rechts. Die Kraft wird über den Kopf 28 auf den Fallenstift 10 übertraten, der die Falle 8 in den Schloßkasten hereinzieht. Bei Loslassen des Türdrückers wird die Falle durch die Feder 9 wieder nach außen bewegt.The movement of the latch 8 via the nut 11 and the door handle, not shown here, takes place as usual when the bolt 3 is not locked. The mandrel 16 strikes the leg 26 of the latch guide 17 and shifts the latch guide on the undercut 18 of the latch link 19 to the right. The force is transferred via the head 28 to the latch pin 10, which pulls the latch 8 into the lock case. When the lever handle is released, the catch is moved outwards again by the spring 9.
