Abstract

A locking system for a door or window has a main lock operated by a handle and/or key and a secondary lock operated by a slider (5) coupled to a rack and pinion servo drive. The connection between the rack and the slider is via a pin and slot which, when the servo drive is set into the parking position, provides sufficient movement in the coupling to cater for manual operation of the lock, i.e. the lock can be operated manually without dragging the servo drive. The maximum play in the coupling exceeds the manual displacement by 2 mm in either direction. The invention is also applicable to locking systems with a servo drive for both the main and secondary catches.

Description

Die Erfindung betrifft eine Schließanlage, insbesondere einen Türverschluss, Fensterverschluss oder dergleichen, mit einem drücker- und schlüsselbetätigbaren Zentralschloss, einem motorischen Antriebsaggregat, einer Trabantenverriegelung und mit einer Treibstange, die zur Betätigung der Trabantenverriegelung von dem Zentralschloss und dem Antriebsaggregat antreibbar ist, wobei das Antriebsaggregat mittels eines motorischen Antriebs unter Zwischenschaltung eines Getriebes und einer Zahnstange auf die Treibstange arbeitet. - Bei einer derartigen Schließanlage mit Mehrfachverriegelung kann anstelle der Drückeroder Schlüsselbetätigung auch der motorische Antrieb die Schließ- bzw. Öffnungsfunktion übernehmen. Dazu wird die rückwärtig des Schlossstulps befindliche Treibstange wie bei der Drücker- oder Schlüsselbetätigung von dem motorischen Antrieb bewegt, bei dem es sich regelmäßig um einen Elektromotor handelt.The invention relates to a locking system, in particular a door lock, window closure or the like, with a push-button and key-operated central lock, a motor drive unit, a Trabantenverriegelung and with a drive rod which is driven to actuate the Trabantenverriegelung of the central lock and the drive unit, wherein the drive unit works by means of a motor drive with the interposition of a gear and a rack on the drive rod. - In such a locking system with multiple locking can take over the closing or opening function instead of the pusher or key operation and the motor drive. For this purpose, the drive rod located at the rear of the lock plate is moved by the motor drive, as is the case with the handle or key operation, which is usually an electric motor.

Bei einer bekannten Ausführung weist das Letztrad des elektromotorisch angetriebenen Getriebes eine Zahnscheibe auf, die einen Bogenschlitz besitzt, dessen Länge größer als 180° ist. In diesen Bogenschlitz greift ein Mitnehmerzapfen ein, der einer unten liegenden zweiten Zahnscheibe zugeordnet ist. Diese zweite Zahnscheibe kämmt mit einer Zahnstange, die fest mit der Treibstange verbunden ist. Auf diese Weise will man vermeiden, dass bei einer manuellen Betätigung des Türdrückers oder Schlüsselbetätigung des Zentralschlosses das gesamte Getriebe mitgedreht werden muss, zumal es sich konstruktionsbedingt um ein selbsthemmendes Getriebe handelt (vgl. EP 1 213 425 A1 ). Bei dieser bekannten Ausführungsform wird über den Bogenschlitz praktisch ein Freigang als Drehbewegungsspiel am Letztrad des Getriebes verwirklicht.In a known embodiment, the final gear of the electric motor-driven gear on a toothed disc, which has a curved slot whose length is greater than 180 °. In this curved slot engages a driving pin, which is associated with a lower lying second toothed disc. This second toothed disc meshes with a rack which is firmly connected to the drive rod. In this way you want to avoid that in a manual operation of the door handle or key operation of the central lock the entire transmission must be rotated, especially as it is by design to a self-locking Transmission acts (see. EP 1 213 425 A1 ). In this known embodiment, virtually a clearance is realized as a rotary motion clearance on the final gear of the transmission on the curved slot.

Der Erfindung liegt die Aufgabe zugrunde, eine Schließanlage, insbesondere einen Türverschluss, Fensterverschluss oder dergleichen der eingangs beschriebenen Ausführungsform zu schaffen, bei dem auf möglichst einfache und kostengünstige Weise ein Freigang verwirklicht ist, um bei Drücker- oder Schlüsselbestätigung des Zentralschlosses ein Mitdrehen des Getriebes zu vermeiden.The invention has for its object to provide a locking system, in particular a door lock, window closure or the like of the embodiment described above, in which in the simplest and most cost-effective manner a clearance is realized to turn on the pusher or key confirmation of the central lock a co-rotation of the transmission avoid.

Diese Aufgabe löst die Erfindung bei einer gattungsgemäßen Schließanlage dadurch, dass die Zahnstange mit einem Mitnehmer in ein Langloch der Treibstange eingreift, und dass das Langloch eine die Mitnehmerlänge übersteigende Hublänge aufweist, der zumindest ein der Drücker- oder Schlüsselbetätigung des Zentralschlosses entsprechender Leerhub entspricht. Durch diesen Leerhub wird ein Freiraum verwirklicht, der die Drücker- bzw. Schlüsselbetätigung des Zentralschlosses ermöglicht, ohne dass das Getriebe des elektromotorischen Antriebs mitgedreht wird. In diesem Zusammenhang geht die Erfindung von der Erkenntnis aus, dass der elektromotorische Antrieb nach Beendigung einer Vor- oder Rückschlussbetätigung wieder in eine Park- oder Mittelstellung zurückdreht. In dieser Park- oder Mittelstellung nimmt der Mitnehmer an der Zahnstange eine Position in dem Langloch ein, die eine drücker- oder schlüsselbetätigte Treibstangenverlagerung erlaubt, ohne das Getriebe mitzubewegen. Aufgrund der Motorsteuerung ist die Park- oder Mittelstellung erfindungsgemäß so ausgelegt, dass sich die Zahnstange innerhalb eines Toleranzbereiches von + 2mm in jede Verschieberichtung bewegen kann. Die vom Letztrad des Getriebes angetriebene Zahnstange ist vorzugsweise so schmal ausgebildet, dass einerseits das Gehäuse des elektromotorischen Antriebs im Zahnstangenbereich äußerst flach gehalten werden kann, andererseits die Zahnstange innerhalb des Euronutkanals eines Tür- oder Fensterprofils untergebracht werden kann. - Stets ist bei der erfindungsgemäßen Schließanlage eine leichte Betätigung des Zentralschlosses durch Türdrücker oder Schlüssel möglich, da Reibungskräfte des Getriebes des elektromotorischen Antriebsaggregats umgangen werden. Darüber hinaus wird eine besonders kostengünstige und einfache Fertigung erreicht, weil lediglich ein entsprechendes Langloch zusätzlich in die Treibstange gestanzt werden muss. Durch den schmalen Aufbau der Zahnstange kann diese nicht nur innerhalb des Euronutkanals verlaufen, sondern das restliche Antriebsgehäuse für das Antriebsaggregat kann so klein wie möglich gehalten werden. Dadurch wird auch die Ausfräsung und somit Schwächung des Tür- oder Fensterprofils möglichst kleingehalten.This object is achieved by the invention in a generic locking system, characterized in that the rack engages with a driver in a slot of the drive rod, and that the slot has a driver length exceeding stroke length corresponding to at least one of the pusher or key operation of the central lock corresponding idle stroke. Through this idle stroke, a free space is realized, which allows the pusher or key operation of the central lock, without the gear of the electric motor drive is rotated. In this context, the invention is based on the recognition that the electromotive drive returns to a parking or center position after completion of a forward or reverse operation. In this parking or center position, the driver on the rack takes a position in the slot, which allows a push-button or key-operated espagnolette without moving the gear. Due to the engine control is the parking or center position according to the invention designed so that the rack can move within a tolerance range of + 2mm in each direction of displacement. The driven by the final gear of the gear rack is preferably designed so narrow that on the one hand, the housing of the electric motor drive in the rack area can be kept extremely flat, on the other hand, the rack can be accommodated within the Euronutkanals a door or window profile. - Always easy operation of the central lock by door handle or key is possible in the locking system according to the invention, since frictional forces of the transmission of the electric motor drive unit are bypassed. In addition, a particularly cost-effective and simple production is achieved because only a corresponding slot must be additionally punched in the drive rod. Due to the narrow construction of the rack, this can not only run within the Euronutkanals, but the remaining drive housing for the drive unit can be kept as small as possible. As a result, the cutout and thus weakening of the door or window profile is kept as small as possible.

In den Figuren ist eine Schließanlage mit einem drückerund schlüsselbetätigbaren Treibstangenschloss als Zentralschloss 1 dargestellt. Ferner weist diese Schließanlage ein motorisches Antriebsaggregat 2 und eine Trabantenverriegelung 3 auf. Auf der Rückseite eines Schlossstulpes 4 verläuft eine Treibstange 5, die zur Betätigung der Trabantenverriegelung 3 bzw. deren Riegel 6 von dem Zentralschloss 1 und dem Antriebsaggregat 2 antreibbar ist. Das Antriebsaggregat 2 arbeitet mittels eines elektromotorischen Antriebs bzw. Elektromotoren M unter Zwischenschaltung eines Getriebes 7 und einer Zahnstange 8 auf die Treibstange 5. Die Zahnstange 8 greift mit einem Mitnehmer 9 in ein Langloch 10 der Treibstange 5 ein. Das Langloch 10 weist eine die Mitnehmerlänge L übersteigende Hublänge H auf, der zumindest ein der Drücker- oder Schlüsselbetätigung des Zentralschlosses 1 entsprechender Leerhub entspricht. Die Zahnstange 8 mit dem Mitnehmer 9 weist ein Bewegungsspiel von + 2mm in beide Verschieberichtungen auf und ist hinreichend schmal zur Unterbringung in den Euronutkanal 11 eines Tür- oder Fensterprofils ausgebildet.In the figures, a locking system with a push-button and key-operated espagnolette lock is shown as the central lock 1. Furthermore, this locking system has a motor drive unit 2 and a Trabantenverriegelung 3. On the back of Schlossstulpes 4 extends a drive rod 5, which is drivable for actuating the Trabantenverriegelung 3 and the latch 6 of the central lock 1 and the drive unit 2. The drive unit 2 operates by means of an electric motor drive or electric motors M with the interposition of a transmission 7 and a rack 8 on the drive rod 5. The rack 8 engages with a driver 9 in a slot 10 of the drive rod 5 a. The slot 10 has a driver length L exceeding stroke length H, which corresponds to at least one of the pusher or key operation of the central lock 1 corresponding idle stroke. The rack 8 with the driver 9 has a movement play of + 2mm in both displacement directions and is sufficiently narrow to accommodate in the Euronutkanal 11 of a door or window profile.

Bei der in Fig. 3 dargestellten Funktionsstellung befindet sich der Mitnehmer 9 in Park- oder Mittelstellung. Nach Fig. 4 ist die Tür geöffnet. In dieser Öffnungs-Position des Mitnehmers 9 sind die Riegel 6 der Mehrfachverriegelung - also Trabantenverriegelung 3 und auch der Riegel 12 des Zentralschlosses - zurückgezogen. Das gilt auch für die Falle 13 des Zentralschlosses 1. Bei der Ausführungsform nach Fig. 5 ist die Tür geöffnet. In dieser Öffnungsposition sind die Riegel 6, 12 zurückgefahren, während die Falle 13 federbeaufschlagt hervortritt. Die Treibstange 5 ist entlastet, weil der Mitnehmer 9 der Zahnstange 8 einen Leerhub und somit in seine Park- bzw. Mittelstellung fährt bzw. gefahren ist. Nach Fig. 6 befindet sich die Tür in geschlossener Position, in welcher die Riegel 6, 12 ausgefahren sind. Die Zahnstange 8 bzw. der Mitnehmer 9 befindet sich noch in ausgefahrener Stellung. Nach Fig. 7 ist die Tür verriegelt. Die Riegel 6, 12 sind ausgefahren, jedoch ist die Zahnstange 8 mit dem Mitnehmer 9 motorgetrieben wieder in Park- bzw. Mittelstellung gefahren.At the in Fig. 3 illustrated functional position is the driver 9 in parking or mid-position. To Fig. 4 the door is open. In this opening position of the driver 9, the bolt 6 of the multiple locking - so Trabantenverriegelung 3 and also the latch 12 of the central lock - retracted. This also applies to the case 13 of the central castle 1. In the embodiment according to Fig. 5 the door is open. In this opening position, the latch 6, 12 retracted while the case 13 spring-loaded emerges. The drive rod 5 is relieved because the driver 9 of the rack 8 a Leerhub and thus moves into its parking or mid-position or is driven. To Fig. 6 is the door in the closed position in which the latch 6, 12 are extended. The rack 8 and the driver 9 is still in the extended position. To Fig. 7 the door is locked. The latch 6, 12 are extended, but the rack 8 is motor driven with the driver 9 again parked or mid-position.
