Description

Die Erfindung betrifft ein Mehrriegelschloss mit Wechselbetätigung und Schubstangenverbindung zu mindestens einem der Riegel, wobei zwischen einem riegelseitigen Schubstangenstück und einem antriebsseitigen Schubstangenstück eine Mitnehmerverbindung mit Freistellung, insbesondere einerseits ein schubstangenfester Mitnehmer, der anderseits in ein Langloch des anderen Schubstangenstückes eingreift, vorgesehen ist.The invention relates to a multi-bolt lock with alternating actuation and push rod connection to at least one of the bolts, a driver connection with an exemption, in particular on the one hand, a push rod-fixed driver which, on the other hand, engages in an elongated hole of the other push rod part, being provided between a bolt-side push rod part and a drive-side push rod part.

Wenn über einen Schließzylinder oder einen Drücker ein Mehrriegelschloss betätigt wird, dann werden Riegel mittels Schubstangen in die Sperrstellung ausgeschoben bzw. aus der Sperrstellung zurückgezogen. Zum Ausgleich von Toleranzen, einschließlich des jeweils unterschiedlichen Türspalts, der ja von einem Riegel überbrückt werden muss, ist es bekannt, im Zuge der Kinematik zwischen einem schlossseitigen Antrieb und einem Riegel ein federndes Ausgleichselement so einzubauen, dass die Schubstangen noch weiter verschoben werden können, selbst dann, wenn der Riegel mit seiner Stirnseite bereits am Grund einer Riegeltasche eines Schließstückes anliegt. Dies ist erforderlich, um beispielsweise mit dem die Schlossmechanik betätigenden Flachschlüssel wieder die Schlüsselabzugstellung zu erreichen. Das Ausgleichselement ist dabei als Feder ausgebildet, die den Riegel gegen die antreibende Schubstange puffert.If a multi-bolt lock is actuated via a locking cylinder or a handle, bolts are pushed out into the locked position or withdrawn from the locked position using push rods. To compensate for tolerances, including the different door gap, which must be bridged by a bolt, it is known to install a resilient compensating element in the course of the kinematics between a lock-side drive and a bolt so that the push rods can be moved even further, even if the end of the bolt is already resting against the bottom of a bolt pocket of a striker. This is necessary, for example, to return to the key withdrawal position with the flat key that actuates the lock mechanism. The compensating element is designed as a spring that buffers the bolt against the driving push rod.

In diesem Sinne betrifft die DE 38 26 802 A1 ein Treibstangenschloss mit Schließzylinder, der einen Treibstangenschieber mit Zahnleiste über ein Zahntrieb betätigt. Zwischen dem Treibstangenschieber und der Zahnleiste ist eine Relativbewegung zur Schaffung eines Bewegungsspiels möglich. Dieses Bewegungsspiel in Ausschubrichtung der Treibstange entspricht dem Drehwinkel der Schließnase des Schließzylinders aus der Einbaustellung in die Schloss-Einstecköffnung bis zur Schlüsselabzugstellung.In this sense, DE 38 26 802 A1 relates to an espagnolette lock with a lock cylinder, which actuates an espagnolette slide with toothed rack via a pinion. A relative movement to create a play of movement is possible between the connecting rod slide and the toothed rack. This movement in the extension direction of the drive rod corresponds to the angle of rotation of the locking lug of the locking cylinder from the installation position into the lock insertion opening until the key is withdrawn.

Eine gänzlich andere Forderung hat ein Mehrriegelschloss zu erfüllen, wenn es aufgesperrt, also der Riegel aus dem Schließstück zurückgezogen wird. Es muss bei eingezogenem Riegel mithilfe des Riegelantriebs noch die Fallenbetätigung erfolgen. Diese könnte mit dem Riegelrückzug derart gekoppelt sein, dass ein Teil des Rückzugweges der Riegel auch für den Fallenrückzug genutzt wird, etwa dadurch, dass die Riegel kurzzeitig in das Innere des Riegelgehäuses zurückgezogen werden und mit dieser Antriebsbewegung über einen Wechsel die Falle betätigt wird. Damit geht aber ein Teil des Weges für die Riegel verloren.A completely different requirement has to be met by a multi-bolt lock when it is unlocked, i.e. the bolt is withdrawn from the striker. When the bolt is drawn in, the latch actuation must still be carried out using the bolt drive. This could be coupled with the bolt retraction be that part of the retraction path of the bolt is also used for the latch retraction, for example by briefly retracting the bolt into the interior of the bolt housing and actuating the latch with this drive movement via a change. However, part of the way for the bars is lost.

Die Erfindung zielt darauf ab, eine Fallenbetätigung bei stillstehendem Riegel in dessen unverändert bleibender Offenstellung zu ermöglichen. Dies wird dadurch erreicht, dass die Freistellung in Richtung des Rückzuges des mindestens einen Riegels vorgesehen ist. Es ist zweckmäßig, wenn eine Feder an der Mitnehmerverbindung angreift'und sich mit je einem Federende an jeweils einem der Schubstangenstücke, diese im Sinne einer Verkürzung ihrer wirksamen Gesamtlänge vorspannend, abstützt und wenn ein Anschlag zur Begrenzung des Verschiebeweges des riegelseitigen Schubstangenstückes bei vollständig zurückgezogenem Riegel vorgesehen ist. Als riegelseitiges Schubstangenstück kann auch ein Riegelschaft vorgesehen sein, der über die Mitnehmerverbindung mit Freistellung an die antriebsseitige Schubstange angeschlossen ist. Die beiden Schubstangenstücke übergreifen einander und die Feder ist im Überlappungsbereich vorgesehen, die an Auflagen an den Enden der Schubstangenstücke, insbesondere an L-förmigen Abwinkelungen, anliegt und die Enden des Überlappungsbereichs auseinander drückt. Ferner ist es zweckmäßig, wenn die Auflagen, insbesondere die L-förmigen Abwinkelungen jedes Schubstangenstückes jeweils am gegenüber liegenden Schubstangenstück geführt sind und wenn eine der Abwinkelungen in ein Langloch des anderen Schubstangenstückes eintaucht und in diesem als Mitnehmer gegen die Kraft der Feder begrenzt verschiebbar ist. Die Länge des Langloches bestimmt den Weg, der für den Hub des Wechselhebels für die Fallenbetätigung notwendig ist. Beim Verriegeln kommt die Feder, anders als beim Stand der Technik, nicht zur Wirkung, weil die antreibende Schubstange bzw. deren Mitnehmer in Vorschubrichtung unmittelbar (also ohne Zwischenschaltung der Feder) an der riegelseitigen Schubstange, dem riegelseitigen Schubstangenstück oder allenfalls dem Riegelschaft anliegt. Erst beim Riegelrückzug kommt die Feder zur Wirkung. Wenn die Feder stärker als der Reibungswiderstand des riegelseitigen Schubstangenstückes und des Riegels im Schließstück ist, dann zieht das in Rückzugrichtung vom Schlossgetriebe angetriebene Schubstangenstück das über die erfindungsgemäß ausgebildete Mitnehmerverbindung angeschlossene riegelseitige Mitnehmerstück unmittelbar zurück, ohne dass die Feder zusammengedrückt wird. Erst dann, wenn der Riegel vollständig eingezogen ist und das riegelseitige Schubstangenstück an einem Anschlag vorzugsweise im Schlosskasten anliegt, führt eine fortgesetzte Betätigung der Schlossmechanik (z.B. mittels des Schlüssels) zu einer fortgesetzten Verschiebung des antriebsseitigen Schubstangenstückes allein. Der oder die Riegel bewegen sich nicht, jedoch wird die Feder zwischen den zwei Schubstangenstücken zusammengedrückt. Dieser Verschiebungsweg bzw. Drehwinkel des oder eines der antreibenden Getriebezahnräder wird über einen Wechselhebel mithilfe eines Zapfens auf der Flachseite des vorgenannten Zahnrades in einem Hub umgesetzt, der über einen Winkelhebel zum Einziehen der Falle führt. Die Falle wird durch eine Fallenfeder wieder ausgeschoben. Die erfindungsgemäße Ausbildung gestattet somit eine Fallenbetätigung mit dem Schlüssel sowie auch mit dem Drücker, je nach Bauart des Schlosses.The invention aims to enable a latch actuation when the bolt is stationary in its open position which remains unchanged. This is achieved in that the exemption is provided in the direction of the withdrawal of the at least one bolt. It is expedient if a spring engages the driver connection and is supported with one spring end on each of the push rod pieces, prestressing them in the sense of shortening their effective total length, and if a stop to limit the displacement path of the bolt-side push rod piece with the bolt fully retracted is provided. A bolt shaft can also be provided as a bolt-side push rod piece, which is connected to the drive-side push rod via the driver connection with an exemption. The two push rod pieces overlap one another and the spring is provided in the overlap area, which rests on supports at the ends of the push rod pieces, in particular on L-shaped bends, and presses the ends of the overlap area apart. It is also expedient if the supports, in particular the L-shaped bends of each push rod piece, are each guided on the opposite push rod piece and if one of the bends is immersed in an elongated hole of the other push rod piece and can be displaced to a limited extent as a driver against the force of the spring. The length of the elongated hole determines the path that is necessary for the stroke of the change lever for the latch actuation. When locking, the spring, unlike in the prior art, does not come into effect because the driving push rod or its driver bears directly against the bolt-side push rod, the bolt-side push rod piece or at most the bolt shaft in the feed direction (i.e. without interposing the spring). The spring only comes into effect when the bolt is withdrawn. If the spring is stronger than the frictional resistance of the bolt-side push rod piece and the bolt in the striker, then the push rod piece driven in the retraction direction by the lock gear immediately pulls back the bolt-side driver piece connected via the driver connection designed according to the invention, without the spring being compressed. Only when the bolt is fully retracted and the bolt-side push rod piece lies against a stop, preferably in the lock case, does a continued actuation of the lock mechanism (e.g. by means of the key) lead to a continued displacement of the drive-side push rod piece alone. The bolt or bolts do not move, but the spring between the two push rod pieces is compressed. This displacement path or angle of rotation of the or one of the driving gearwheels is implemented via a change lever with the aid of a pin on the flat side of the aforementioned gearwheel in a stroke which leads to the retraction of the latch via an angle lever. The trap is pushed out again by a trap spring. The design according to the invention thus allows the latch to be actuated with the key and also with the handle, depending on the design of the lock.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. Fig. 1 zeigt ein Mehrriegelschloss in schematischer Darstellung im gesperrten Zustand mit ausgeschobener Schubstange bzw. Riegel, Fig. 2 zeigt das Schloss nach Fig. 1 mit eingezogenem Riegel und mit Wechsel zur Fallenbetätigung und Fig. 3 das Schloss nach Fig. 2 während der Wechselbetätigung mit stillstehendem Riegel und eingezogener Falle.An embodiment is shown in the drawing. Fig. 1 shows a multi-bolt lock in a schematic representation in the locked state with the push rod or bolt pushed out, Fig. 2 shows the lock according to Fig. 1 with the bolt engaged and with a change to the latch actuation and Fig. 3 the lock according to Fig. 2 during the change actuation with a dead bolt and a retracted latch.

Ein Mehrriegelschloss nach Fig. 1 umfasst ein von einem Schließzylinder über deren Sperrnase betätigtes Getriebe mit einem abtreibenden Getriebezahnrad 1, das mit einer Sperrnase 2 im Eingriff steht. Die Zahnstange 2 ist Teil eines antriebsseitigen Schubstangenstückes 3, welches in seinem Endbereich ein riegelseitiges Schubstangenstück 4 übergreift. Beide Schubstangenstücke 3 und 4 sind linear geführt. Das Schubstangenstück 4 ist an seinem schlossfernen Ende mit seinem Riegel 5 verbunden. Ferner trägt das Schubstangenstück 4 eine Verzahnung 6, in die ein Ritzel 7 eingreift, welches eine entgegengesetzt wirkende Schubstange 8 verschiebt.A multi-bolt lock according to FIG. 1 comprises a gear operated by a locking cylinder via its locking lug with an abortive gear wheel 1 which is in engagement with a locking lug 2. The rack 2 is part of a drive-side push rod piece 3, which overlaps a bolt-side push rod piece 4 in its end region. Both push rod pieces 3 and 4 are guided linearly. The push rod piece 4 is connected to its bolt 5 at its end remote from the lock. Furthermore, the push rod piece 4 a toothing 6, in which a pinion 7 engages, which displaces an oppositely acting push rod 8.

Die Enden der Schubstangenstücke 3, 4 sind im Überlappungsbereich zu Auflagen L-förmig abgebogen. Das Ende des Schubstangenstückes 3 bildet einen Mitnehmer 9, der in ein Langloch 10 des Schubstangenstückes 4 eingreift. Zwischen den Auflagen der Schubstangenstücke 3 und 4 ist eine Feder 11 vorgesehen, die die Auflagen auseinander drückt, wodurch die Schubstangenstücke 3 und 4 gegeneinander im Sinne einer Verkürzung der Gesamtlänge der Schubstangenstücke vorgespannt sind.The ends of the push rod pieces 3, 4 are bent into L-shaped supports in the overlap area. The end of the push rod piece 3 forms a driver 9 which engages in an elongated hole 10 of the push rod piece 4. Between the supports of the push rod pieces 3 and 4 a spring 11 is provided which presses the supports apart, whereby the push rod pieces 3 and 4 are biased against each other in the sense of shortening the total length of the push rod pieces.

Gemäß Fig. 1 wird durch Betätigung des Getriebezahnrades 1 im Uhrzeigersinn das Schubstangenstück 3 nach oben verschoben. Der Mitnehmer 9 liegt am oberen Ende des Langloches 10 an und schiebt das Schubstangenstück 4 sowie den Riegel 5 nach oben.1, the push rod piece 3 is moved upwards by actuating the gear wheel 1 in a clockwise direction. The driver 9 rests against the upper end of the elongated hole 10 and pushes the push rod piece 4 and the bolt 5 upwards.

Unter der Voraussetzung, dass die Feder 11 hart ist, bleibt die Relativlage der Schubstangenstücke 3, 4 zueinander auch dann gleich, wenn das Getriebezahnrad gegen den Uhrzeigersinn verdreht wird. Das antriebsseitige Schubstangenstück 3 drückt oder schiebt das riegelseitige Schubstangenstück nach unten. Die Feder 11 bleibt vorerst in ihrer Länge gleich und der Mitnehmer 9 liegt weiterhin am oberen Ende des Langloches 10 bzw. einer entsprechenden Ausnehmung an. Das Zurückdrücken des Riegels 5 und des Schubstangenstückes 4 erfolgt über die Feder 11, deren Federkraft größer als die Reibung des Schubstangenstückes 4, einschließlich des Reibungswiderstandes des Riegels 5 in der Schließstücktasche 12, ist. Die Verschiebung des riegelseitigen Schubstangenstückes 4 endet dann, wenn Letztere mit ihrem L-förmigen Endstück an einem Anschlag 13 anliegt.Provided that the spring 11 is hard, the relative position of the push rod pieces 3, 4 to one another remains the same even when the gear wheel is turned counterclockwise. The drive-side push rod piece 3 pushes or pushes the bolt-side push rod piece down. For the time being, the spring 11 remains the same in length and the driver 9 continues to rest against the upper end of the elongated hole 10 or a corresponding recess. The bolt 5 and the push rod piece 4 are pushed back via the spring 11, the spring force of which is greater than the friction of the push rod piece 4, including the frictional resistance of the bolt 5 in the striker pocket 12. The displacement of the bolt-side push rod piece 4 ends when the latter abuts a stop 13 with its L-shaped end piece.

Über den Schlüssel kann aber das antriebsseitige Schubstangenstück 3 bei stillstehendem Riegel 5 und stillstehendem riegelseitigen Schubstangenstück 4 noch weiter eingeschoben werden, wie dies im Übergang von Fig. 2 zu Fig. 3 dargestellt ist.With the key, however, the drive-side push rod piece 3 can be pushed in even further when the bolt 5 is stationary and the dead-end push rod piece 4 is stationary, as is shown in the transition from FIG. 2 to FIG. 3.

Die Fig. 2 und 3 zeigen zusätzlich zu Fig. 1 noch einen Wechsel zur Fallenbetätigung in Prinzipdarstellung. Gemäß Fig. 2 und 3 liegt im Drehkreis eines Mitnehmerzapfens 14 auf der Flachseite des Zahnrades 1 ein Wechselhebel 15, der vom Zapfen 14 mitgenommen wird, wenn das riegelseitige Schubstangenstück 4 am Ende des Verschiebungsweges am Anschlag 13 anliegt. Der Riegel 5 ist in dieser in Fig. 2 dargestellten Position zur Gänze eingezogen. Er hat den Weg A zurückgelegt, der dem maximalen Riegelausschluss von z.B. 20 mm entspricht. Bei fortgesetzter Schlüsseldrehung wird die Feder 11 zusammen gedrückt, wobei dazu der Weg B von beispielsweise 3 mm zur Verfügung steht. Fig. 3 zeigt diese Situation, in der über den Schlüssel der Wechsel betätigt wird. Der Mitnehmerzapfen 14 hebt den Wechselhebel 15 an, der seinerseits einen Winkelhebel 16 um die Achse 17 dreht und eine Falle 18 einzieht. Dazu sind sowohl zwischen Wechselhebel 15 und dem Winkelhebel 16 als auch zwischen dem Winkelhebel 16 und dem Fallenschäft Stift- Langlochverbindungen. So bewirkt das Langloch 19 (Fig. 2), dass die Falle 18 etwa beim Zustoßen der Tür durch äußere Kräfte, eingeschoben wird, ohne dass der Wechselhebel 15 angehoben wird.2 and 3 show, in addition to FIG. 1, a change to the latch actuation in a basic representation. 2 and 3 is in the turning circle of a driver pin 14 the flat side of the gear 1, a change lever 15 which is carried by the pin 14 when the bolt-side push rod piece 4 rests against the stop 13 at the end of the displacement path. The bolt 5 is fully retracted in this position shown in Fig. 2. He has traveled the distance A, which corresponds to the maximum deadbolt exclusion of, for example, 20 mm. When the key continues to be turned, the spring 11 is pressed together, for which purpose the path B of, for example, 3 mm is available. Fig. 3 shows this situation in which the change is actuated via the key. The driver pin 14 lifts the change lever 15, which in turn rotates an angle lever 16 about the axis 17 and pulls in a latch 18. For this purpose, there are pin-slot connections between the change lever 15 and the angle lever 16 as well as between the angle lever 16 and the latch shaft. The elongated hole 19 (FIG. 2) thus causes the latch 18 to be pushed in, for example when the door is pushed in by external forces, without the change lever 15 being raised.

Wäre nun die Feder 11 nicht stark genug, um den Weg B im Übergang von Fig. 1 zu Fig. 2 stets aufrecht zu erhalten, weil etwa die Reibung des Riegels 5 in der Riegeltasche 12 sehr groß ist, dann würde der Mitnehmer 9 bzw. die Auflagen des Schubstangenstückes 3 die Feder 11 ausgehend von Fig. 1 sofort spannen, bis der Mitnehmer 9 nach Durchmessen des Weges B am unteren Ende des Langlochs (ähnlich wie in Fig. 3) anliegt. Über das Getriebe wird der Riegel 5 dann bei gespannter Feder außer Eingriff mit der Riegeltasche 12 gebracht, wobei in diesem Moment der Reibungswiderstand des Riegels 5 entfällt und sich die Feder 11 auf die Vorspannung gemäß Fig. 1 und Fig. 2 entspannt. Beim weiteren Aufsperren mithilfe des Schlüssels stößt dann bei vollständig eingezogenem Riegel 5 das Schubstangenstück 4 gegen den Anschlag 12, wie dies in Fig. 2 dargestellt ist und es steht die Weglänge B für die Wechselbetätigung (Fig. 3) zur Verfügung. Das Getriebe mit dem abtreibenden Zahnrad 1 könnte auch durch einen Drücker betätigt werden.If the spring 11 were not strong enough to always maintain the path B in the transition from FIG. 1 to FIG. 2, for example because the friction of the bolt 5 in the locking pocket 12 is very large, the driver 9 or the supports of the push rod piece 3, starting from FIG. 1, immediately tension the spring 11 until the driver 9, after measuring the path B, rests against the lower end of the elongated hole (similar to that in FIG. 3). When the spring is under tension, the bolt 5 is then brought out of engagement with the bolt pocket 12, the frictional resistance of the bolt 5 being eliminated at this moment and the spring 11 relaxing to the pretension according to FIGS. 1 and 2. Upon further unlocking using the key, the push rod piece 4 then abuts against the stop 12 when the bolt 5 is fully retracted, as shown in FIG. 2, and the path length B is available for the changeover operation (FIG. 3). The gear with the driven gear 1 could also be actuated by a pusher.

Claims (5)

  1. Multiple bolt lock with two-way operation and connection by pushrod to at least one of the bolts, wherein a catch connection with release is provided between a bolt-side pushrod-piece and a drive-side pushrod-piece, in particular a catch integral with or rigidly attached to one pushrod[-piece] which engages in a slot in the other pushrod-piece, characterized in that the release is provided in the withdrawal direction of the at least one lock (5).
  2. Multiple bolt lock according to Claim 1, characterized in that a spring (11) acts on the catch connection and bears at either end on the pushrod-pieces (3, 4), preloading them so as to shorten their effective overall length, and in that a stop (13) is provided to limit the displacement of the bolt-side pushrod-piece (4) when the bolt (5) is fully withdrawn.
  3. Multiple bolt lock according to Claim 1 or Claim 2, characterized in that the bolt-side pushrod-piece (4) is provided directly as a bolt-shaft connected to the drive-side pushrod-piece (3) by the catch connection with release and spring (11).
  4. Multiple bolt lock according to any one of Claims 1 to 3, characterized in that the two pushrod-pieces (3, 4) overlap in the region of the catch connection and in that the spring (11) is provided in the region of overlap and bears on rests at the ends of the pushrod-pieces (3, 4), in particular L-shaped bends, pushing the said ends apart.
  5. Multiple bolt lock according to Claim 4, characterized in that the rests, in particular L-shaped bends, of the pushrod-pieces (3, 4) are each guided on the opposing pushrod-piece (3, 4), and in that one of the bends dips into a slot (10) in the other pushrod-piece (4) and is confinedly displaceable therein against the force of the spring (11), as catch (9).
