Description

Die Erfindung betrifft ein Schloß, insbesondere Mehrriegelschloß, mit einem im Schloßgehäuse angeordneten Zahnradgetriebe, zwischen einem Mitnehmer eines Doppelschließzylinders und einem Riegel und bzw. oder einer Schubstange, sowie mit einem elektrischen Antrieb für die Schloßbetätigung gemäß dem Oberbegriff des Anspruchs 1. Ein solches schloß ist aus der DE-A-3 606 531 bekannt.The invention relates to a lock, in particular a multi-bolt lock, with a gear mechanism arranged in the lock housing, between a driver of a double lock cylinder and a bolt and / or a push rod, and with an electric drive for the lock actuation according to the preamble of claim 1. Such a lock is known from DE-A-3 606 531.

Elektrisch betätigte Schlösser sind als Türöffner oder im Bankenbereich bei Schließfächern bekannt. Meist handelt es sich um komplizierte Sonderkonstruktionen, wenn ein Schloß mit einem Schlüssel händisch oder nach einem Codevergleich elektrisch geöffnet und gesperrt werden soll. Die Notwendigkeit beider Betätigungsarten ergibt sich, da bei Stromausfall oder bei verbrauchter Batterie eine Schloßbetätigung möglich sein muß.Electrically operated locks are known as door openers or in the banking sector for lockers. Usually, these are complicated special constructions when a lock is to be opened and locked manually with a key or after a code comparison. The necessity of both types of actuation results from the fact that a lock actuation must be possible in the event of a power failure or when the battery is used up.

Der Erfindung liegt die Aufgabe zugrunde, ein mechanisches Serienschloß mit Schlüsselbetätigung durch eine externe elektrische Antriebseinheit so zu ergänzen, daß sowohl Handbetrieb als auch elektrischer Betrieb möglich ist. Dies wird durch die Merkmale des Anspruchs 1 erreicht. Da der Mitnehmer eines handelsüblichen Doppelzylinders nur durch den Schlüssel im Zylinder, nicht aber frei gedreht werden kann, ist bei herkömmlichen zylinderbetätigten Schlössern ein Sperrvorgang durch Einleiten einer äußeren Antriebskraft nur dann möglich, wenn sich der Schließzylinder mitdrehen kann. Dies erfordert im allgemeinen das Einstecken des Flachschlüssels, der die Stiftzuhaltungen in die Freigabeposition verschiebt, sodaß die Sperre der Schloßmechanik durch den Mitnehmer des Schließzylinders aufgehoben ist. Um zu erreichen, daß eine elektrische Schloßbetätigung auch ohne Einstecken eines Schlüssels möglich wird, sieht die Erfindung den Einbau eines handelsüblichen Doppelschließzylinders mit innerer Knaufbetätigung vor. Da der bei einer Tür an der Innenseite vorgesehene Knauf mit einem Zylinderkern ohne Stiftzuhaltungen im Zylindergehäuse frei drehbar ist und mit den Mitnehmer in Verbindung steht, wirkt dieser spezielle,jedoch handelsübliche Doppelschließzylinder nicht blockierend auf die Schloßmechanik, wenn eine äußere Antriebskraft auf ein Zahnrad des Getriebes zwischen Doppelschließzylinder und Riegel eingeleitet wird. Es kann also ein gewöhnliches Schloß, insbesondere für Mehrriegelbetätigung, mit Zahnradgetriebe verwendet werden. Ein Nachrüsten des elektrischen Antriebs ist möglich. Der Schlüsselschalter kann einen Schließzylinder der üblichen Bauart aufweisen. Es genügt meist ein Halbzylinder, weil der elektrische Sperr- oder Freigabebefehl nur von einer Seite der Tür erfolgt. Bei einem Mehrriegelschloß wird die Schubstange, welche das Schloß mit den zusätzlichen Verriegelungen verbindet, als Antriebsstange ausgebildet; dadurch kann eine eigene Antriebsstange vermieden werden, wenn der elektrische Antrieb in die Schubstange eines Mehrriegelschlosses eingreift. Das Antriebsgehäuse kann in einer für ein Zusatzschloß vorgesehenen Türausnehmung eingebaut werden und gänzlich in einer Ausstemmung der Tür verschwinden oder in der Art eines Kastenriegelschlosses innen aufgesetzt werden, wobei der Zylinder für den Schlüsselschalter nach außen durchgreift. Zwischen dem Antriebsgehäuse und dem Schloßgehäuse ist die Antriebsstange vorgesehen. Sie ist zwischen Schlitzen in den beiden Gehäusen geführt und greift jeweils im Inneren jedes Gehäuses in ein Zahnrad (einerseits in ein Getriebezahnrad der Schloßmechanik, anderseits in das Antriebsritzel des über ein Untersetzungsgetriebe und eine ausrückbare Kupplung angeschlossenen Motors). Es ist zweckmäßig, wenn dem elektrischen Antrieb eine Kupplung nachgeschaltet ist, die bei Einschalten des Antriebs eingerückt und bei Ausschalten des Antriebes ausgerückt ist. Dadurch kann das Schloß mit dem Schlüssel mechanisch betätigt werden, ohne daß der Motor mit seinem Untersetzungsgetriebe mitgedreht werden muß. Der Schlüsselschalter dient zum Einschalten des Antriebs in der einen oder der anderen Drehrichtung, wobei der Schlüssel im Schloß des Schlüsselhalters bloß geringfügig nach links (zum Zusperren) oder von rechts (zum Aufsperren) gedreht werden muß. Es ist vorteilhaft, wenn der elektrische Antrieb bei Überschreiten eines voreinstellbaren Stromwertes abschaltbar ist. Ein strombegrenzendes Schaltgerät dient auch einer Not-Aus-Schaltung bei Störfällen, wie etwa Sperren bei nicht vollständig geschlossener Tür. Die Schubstange übernimmt dann zusätzlich die Funktion einer Antriebsstange und damit die Übertragung der Antriebskräfte des Antriebs in die Schloßmechanik.The invention has for its object to supplement a mechanical serial lock with key actuation by an external electrical drive unit so that both manual and electrical operation is possible. This is achieved by the features of claim 1. Since the driver of a commercially available double cylinder can only be turned by the key in the cylinder, but not freely, with conventional cylinder-operated locks, a locking process by introducing an external drive force is only possible if the locking cylinder can also rotate. This generally requires the insertion of the flat key, which moves the pin tumblers into the release position, so that the lock of the lock mechanism is released by the driver of the lock cylinder. In order to ensure that an electric lock actuation is possible even without inserting a key, the invention provides for the installation of a commercially available double lock cylinder with an internal knob actuation. Because the one provided on the inside of a door Knauf with a cylinder core without pin tumblers in the cylinder housing can be freely rotated and is connected to the drivers, this special, but commercially available double lock cylinder does not have a blocking effect on the lock mechanism if an external driving force is applied to a gear wheel of the transmission between the double lock cylinder and bolt. It is therefore possible to use an ordinary lock, in particular for multi-bolt actuation, with a gear transmission. The electric drive can be retrofitted. The key switch can have a locking cylinder of the usual type. A half-cylinder is usually sufficient, because the electrical lock or release command is only issued from one side of the door. In the case of a multi-bolt lock, the push rod, which connects the lock to the additional locks, is designed as a drive rod; a separate drive rod can thereby be avoided if the electrical drive engages in the push rod of a multi-bolt lock. The drive housing can be installed in a door recess provided for an additional lock and can disappear entirely in the opening of the door, or can be fitted inside in the manner of a box bolt lock, with the cylinder for the key switch reaching through to the outside. The drive rod is provided between the drive housing and the lock housing. It is guided between slots in the two housings and engages inside a gear wheel inside each housing (on the one hand in a gear wheel of the lock mechanism, on the other hand in the drive pinion of the motor connected via a reduction gear and a disengageable clutch). It is useful if a clutch is connected downstream of the electric drive, which is engaged when the drive is switched on and disengaged when the drive is switched off. As a result, the lock can be operated mechanically with the key without the motor having to be rotated with its reduction gear. The key switch is used to switch the drive on in one or the other direction of rotation, with the key in the lock of the Key holder only has to be turned slightly to the left (to lock) or from the right (to unlock). It is advantageous if the electric drive can be switched off when a preset current value is exceeded. A current-limiting switching device also serves as an emergency stop in the event of malfunctions, such as locking when the door is not completely closed. The push rod then also takes over the function of a drive rod and thus the transmission of the drive forces of the drive into the lock mechanism.

Ausführungsbeispiele des Erfindungsgegenstandes sind in den Zeichnungen dargestellt. Fig. 1 zeigt ein Mehrriegelschloß mit Zusatzriegelgehäusen sowie einen elektrischen Antrieb mit Schlüsselschalter in schematischer Darstellung, Fig. 1a als Detail aus Fig. 1 einen Doppelzylinder in Seitenansicht und Fig. 2 eine alternative Ausführungsform zu Fig. 1.Embodiments of the subject matter of the invention are shown in the drawings. Fig. 1 shows a multi-bolt lock with additional bolt housings and an electric drive with key switch in a schematic representation, Fig. 1a as a detail from Fig. 1 shows a double cylinder in side view and Fig. 2 shows an alternative embodiment to Fig. 1st

In einem Schloßgehäuse 1 sind ein Doppelschließzylinder 2 mit Mitnehmer. 3, ein Getriebe, welches symbolisch durch Zahnräder 4, 5, 6 dargestellt ist, und ein Riegel 7 vorgesehen. Eine Schubstange 8 greift mit einer Verzahnung in das Zahnrad 6, welches auch die Bewegung des Riegels 7 steuert.In a lock housing 1 are a double lock cylinder 2 with a driver. 3, a gear, which is symbolically represented by gears 4, 5, 6, and a bolt 7 is provided. A push rod 8 engages with a toothing in the gear 6, which also controls the movement of the bolt 7.

In einem Antriebsgehäuse 9 ist ein Elektromotor 10 vorgesehen, der in den beiden Drehrichtungen (Linkslauf, Rechtslauf) durch einen Schlüsselschalter 11 mit Betätigung über einen Schließzylinder 12 ansteuerbar ist. Dem Elektromotor 10, der ein Untersetzungsgetriebe (nicht dargestellt) aufweist, ist eine Kupplung 13 nachgeschaltet. Die Kupplung 11 wird selbsttätig eingerückt, sobald der Elektromotor 10 arbeitet. Ein Zahnrad 14 greift in eine Verzahnung einer Antriebsstange 15 und verschiebt diese je nach Drehrichtung nach oben oder nach unten. Die Antriebsstange 15 greift ebenfalls mit einer Verzahnung an dem Zahnrad 5 des Schloßgetriebes an.An electric motor 10 is provided in a drive housing 9 and can be controlled in the two directions of rotation (counterclockwise, clockwise rotation) by a key switch 11 with actuation via a locking cylinder 12. A clutch 13 is connected downstream of the electric motor 10, which has a reduction gear (not shown). The clutch 11 is automatically engaged as soon as the electric motor 10 is working. A gear 14 engages in a toothing of a drive rod 15 and moves it up or down depending on the direction of rotation. The drive rod 15 also engages with a toothing on the gear 5 of the lock gear.

Fig. 1a zeigt den Doppelschließzylinder 2, der auf der Innenseite über einen Knauf 16 verfügt. Solche Doppelschließzylinder sind beispielsweise als "Hotelzylinder" im Handel. Sie können von der Zimmerseite (Innenseite) über den Knauf 16 betätigt werden. Von der Gangseite (Außenseite) muß ein Flachschlüssel verwendet werden, da der äußere Zylinderkern über Stiftzuhaltungen 17 verfügt, die vom Schlüssel in die Freigabestellung zu verschieben sind, damit ein Sperrvorgang durchgeführt werden kann. Der mit dem Knauf 16 starr verbundene innere Zylinderkern ist im Zylindergehäuse frei drehbar. Es sind dort keine Stiftzuhaltungen vorgesehen. Der Mitnehmer 3 steht mit dem inneren Zylinderkern in Verbindung. Dieser Doppelschließzylinder 2 stellt das Getriebe (Zahnräder 4, 5, 6) frei, sodaß jede Verschiebung der Antriebsstange 15 das Getriebe in Bewegung setzt, wobei der Knauf 16 mitgedreht wird. Der Elektromotor 10 treibt somit über die Antriebsstange 15 das Getriebe und in weiterer Folge den Riegel 7 sowie (falls vorhanden) die Schubstange 8 an. Letztere ist parallel zu einer Stulpschiene 18 geführt und steht über Zahnräder 19, 20 mit den Riegeln 21, 22 in kinematischer Verbindung.Fig. 1a shows the double lock cylinder 2, which has a knob 16 on the inside. Such double lock cylinders are commercially available, for example, as "hotel cylinders". They can be operated from the inside of the room (knob 16). A flat key must be used from the aisle side (outside), since the outer cylinder core has pin tumblers 17 which can be moved from the key into the release position so that a locking operation can be carried out. The inner cylinder core rigidly connected to the knob 16 is freely rotatable in the cylinder housing. There are no pin tumblers provided there. The driver 3 is connected to the inner cylinder core. This double lock cylinder 2 releases the gear (gears 4, 5, 6) so that any displacement of the drive rod 15 sets the gear in motion, with the knob 16 also being rotated. The electric motor 10 thus drives the transmission via the drive rod 15 and subsequently the bolt 7 and (if present) the push rod 8. The latter is guided parallel to a faceplate 18 and is in kinematic connection with the bolts 21, 22 via gears 19, 20.

Fig. 2 unterschiedet sich von Fig. 1 dadurch, daß der Elektromotor 10' über die Kupplung 13' und das Zahnrad 14' in eine Verzahnung der Schubstange 8' eingreift, die die Funktion der Antriebsstange 15 nach Fig. 1 übernimmt. Eine Verzahnung der Schubstange 8' kämmt mit dem Zahnrad 6' des Schloßgetriebes (Zahnräder 4', 5', 6') und bewirkt das Verschieben des Riegels 7' je nach der vom Schlüsselschalter 11' gesteuerten Drehrichtung des Elektromotors 10' in Sperrichtung oder Freigaberichtung. Der Doppelschließzylinder 2' entspricht der Ausführung nach Fig. la. Die Funktion der Bauelemente in Fig. 2, wie etwa des steuernden Schließzylinders 12', im Antriebsgehäuse 9' oder des Mitnehmers 3' des Doppelschließzylinders 2' bzw. der Stulpschiene 18' und der Zahnräder 19', 20' und der Riegel 21', 22', entspricht jener der Fig. 1.Fig. 2 differs from Fig. 1 in that the electric motor 10 'via the clutch 13' and the gear 14 'engages in a toothing of the push rod 8', which takes over the function of the drive rod 15 according to Fig. 1. A toothing of the push rod 8 'meshes with the gear 6' of the lock gear (gear wheels 4 ', 5', 6 ') and causes the bolt 7' to be moved depending on the direction of rotation of the electric motor 10 'controlled by the key switch 11' in the blocking direction or release direction . The double lock cylinder 2 'corresponds to the embodiment according to Fig. La. The function of the components in FIG. 2, such as the controlling locking cylinder 12 ', in the drive housing 9' or the driver 3 'of the double locking cylinder 2' or the faceplate 18 'and the gear wheels 19', 20 'and the latch 21', 22 'corresponds to that of FIG. 1.

Bei der Anordnung nach Fig. 1 und 2 kann somit eine Betätigung der Riegel 7, 7', 21, 21', 22, 22' durch kurzes links- oder Rechtsdrehen eines Schlüssels im Schlüsselhalter 11, 11' oder auch durch normale Schlüsselbetätigung allenfalls mit dem selben Schlüssel über den Doppelzylinder 2, 2' oder durch Drehen des Knaufs 16 von der Innenseite her bzw. durch Betätigung des elektrischen Antriebes durch Taster erfolgen.In the arrangement according to FIGS. 1 and 2, actuation of the bolts 7, 7 ', 21, 21', 22, 22 'by briefly turning a key to the left or right in the key holder 11, 11' or also by normal key actuation can at most be carried out the same key over the double cylinder 2, 2 'or by turning the knob 16 from the inside or by actuating the electric drive by button.
