Durch die nicht vorveröffentlichte EP-A 0 235 703 ist ein elektronisches Türschloß für einen mit einem elektrischen Speicher für eine Schlüsselwortinformation versehenen elektronischen Schlüssel vorbekannt, mit einem Schloßgehäuse, einer zumindest von der Türinnenseite her mittels eines Drückers betätigbaren, in ein Schließblech eingreifenden Falle, einem in das Schließblech ausschließbaren Riegel, einem elektrisch steuerbaren Schließmechanismus für den Riegel, einer Leseeinrichtung für die Schlüsselwortinformation des elektronischen Schlüssels und einer den Schließmechanismus abhängig von der gelesenen Schlüsselwortinformation steuernden Steuerschaltung.EP-A 0 235 703, which has not been published beforehand, discloses an electronic door lock for an electronic key provided with an electrical memory for keyword information, with a lock housing, a case which can be actuated at least from the inside of the door by means of a handle and engages in a striking plate into the locking plate lockable bolt, an electrically controllable locking mechanism for the bolt, a reading device for the keyword information of the electronic key and a control circuit controlling the locking mechanism depending on the read keyword information.

In der EP-A 0 235 703 wird der Bedienungskomfort eines elektrischen bzw. elektronischen Türschlosses der gattungsgemäß vorausgesetzten Art dadurch verbessert, daß Sensoren vorgesehen sind, die auch als zwei räumlich unterschiedliche Orientierungen des elektronischen Schlüssels ansprechen, wobei der Schloßmechanismus eine elektrische Antriebseinrichtung, insbesondere einen Elektromotor für die Auf- und Zusperrung des Riegels aufweist, die abhängig von der mittels der Sensoreinrichtung erfaßten Orientierung des elektronischen Schlüssels betreibbar ist. Hierdurch soll erreicht werden, daß die Vorteile elektronischer bzw. elektrischer Türschlösser, insbesondere die Erhöhung der Schließsicherheit, ohne Beeinträchtigung des Bedienungskomforts erhalten bleiben.In EP-A 0 235 703 the ease of use of an electrical or electronic door lock of the generic type assumed is improved in that sensors are provided which also respond as two spatially different orientations of the electronic key, the lock mechanism being an electric drive device, in particular one Has electric motor for unlocking and locking the bolt, which can be operated depending on the orientation of the electronic key detected by the sensor device. This is intended to ensure that the advantages of electronic or electrical door locks, in particular the increase in locking security, are retained without impairing the ease of use.

Bei dem in der EP-A 0 235 703 vorgeschlagenen Türschloß treibt ein Elektromotor den Riegel über ein Zahnstangengetriebe an. Die Blockierung des Riegels in seinen Endstellungen erfolgt über das Zahnradgetriebe, welches bei Gewalteinwendung auf den Riegel beschädigt werden kann.In the door lock proposed in EP-A 0 235 703, an electric motor drives the bolt via a rack and pinion gear. The bolt is locked in its end positions via the gear mechanism, which can be damaged if the bolt is used violently.

Der EP-A 0 235 703 liegt das Problem zugrunde, den Schließmechanismus eines derartigen elektronischen bzw. elektrischen Türschlosses zu vereinfachen, und zwar so, daß dessen elektrischer Antriebsmotor von auf den Riegel extern ausgeübten Kräften entlastet wird. Zu diesem Zweck wird vorgeschlagen, daß der Schließmechanismus eine den Riegel in einer seiner Bewegungsrichtungen antreibende Feder sowie einen den Riegel entgegengesetzt zur Federantriebsrichtung über ein lediglich entgegengesetzt zur Federantriebsrichtung kraftschlüssiges Getriebe antreibenden Elektromotor aufweist, wobei dem Riegel ein über das Getriebe mechanisch steuerbarer Blockriegel . zugeordnet sein soll, der den Riegel zumindest in der in der Motorantriebsrichtung erreichbaren Riegelendstellung blockiert. Der Riegel wird also bei der vorbeschriebenen, nicht vorveröffentlichten EP-A 0 235 703 von dem Elektromotor lediglich in einer Richtung angetrieben, und zwar in das Schloßgehäuse hineinbewegt. Der Elektromotor spannt die den Riegel in der anderen Richtung, also in der Ausschlußrichtung, treibende Feder. Das Getriebe, bei dem es sich bevorzugt um ein Nockengetriebe handeln soll, ist so gestaltet, daß es die Abtriebskraft des Motors lediglich in der dem Motor zugeordneten Antriebsrichtung die Antriebskräfte übertragen kann. Wird hingegen der Motorantriebsrichtung eine Kraft auf den Riegel ausgeübt, so heben die Nocken des Nockengetriebes voneinander ab und entlasten den Elektromotor. Werden in entgegengesetzter Richtung auf den Riegel Kräfte ausgeübt, wird der Motor durch den Blockierriegel geschützt. Der Blockierriegel sperrt den Riegel in beiden Richtungen, so daß der Riegel in beiden Endstellungen fixiert ist und sowohl gegen Einschieben in das Schloßgehäuse als auch gegen Herausziehen geschützt ist. Letzteres könnte z. B. beim Zuschlagen der Tür passieren, wobei dann der Riegel mit Gewalt gegen das Schließblech schlagen würde, wodurch es sowohl am Schließblech als auch an den Schloßeingerichteteilen zu Beschädigungen kommen könnte. Dieser Blockierriegel kann als schwenkbar an dem Schloßgehäuse gelagerte Blockierklinke ausgebildet sein, die federnd im Blockiereingriff mit dem Riegel vorgespannt ist und über einen Steuernockenantrieb abhängig von der Antriebsposition des Antriebes außer Eingriff gebracht werden kann. Die Blockierklinke soll dabei bevorzugt unmittelbar an dem Riegel angreifen.EP-A 0 235 703 is based on the problem of simplifying the locking mechanism of such an electronic or electric door lock, in such a way that its electric drive motor is relieved of forces exerted externally on the bolt. For this purpose, it is proposed that the locking mechanism has a spring driving the bolt in one of its directions of movement and an electric motor driving the bolt opposite to the spring drive direction via an electric motor which only positively engages in the opposite direction to the spring drive direction, the bolt having a block bolt mechanically controllable via the transmission. should be assigned, which blocks the bolt at least in the bolt end position achievable in the motor drive direction. In the above-described, not previously published EP-A 0 235 703, the bolt is thus driven by the electric motor in only one direction, namely into the lock housing. The electric motor tensions the spring driving the bolt in the other direction, that is, in the direction of exclusion. The gearbox, which is preferably a cam gearbox, is designed in such a way that the output force of the motor can only transmit the driving forces in the drive direction assigned to the motor. If, on the other hand, a force is exerted on the bolt in the motor drive direction, the cams of the cam gear lift up from one another and relieve the load on the electric motor. If forces are exerted on the bolt in the opposite direction, the motor is protected by the blocking bolt. The locking bolt locks the bolt in both directions, so that the bolt is fixed in both end positions and is protected both against insertion into the lock housing and against pulling out. The latter could e.g. B. happen when slamming the door, then the bolt would strike violently against the striking plate, which could result in damage to both the striking plate and the lock parts. This locking bolt can be designed as a pivotally mounted locking pawl which is resiliently biased in blocking engagement with the bolt and can be disengaged via a control cam drive depending on the drive position of the drive. The locking pawl should preferably engage directly on the bolt.

Das Türschloß soll lediglich auf der Türinnenseite, d. h. der geschützten Seite der Tür, einen mit der Falle gekuppelten Türdrücker aufweisen. Von der Außenseite der Tür her wird die Falle von dem auf den Riegel antreibenden Elektromotor betätigt. Hierzu ist vorgesehen, daß der Riegel über die vom Blockierriegel bestimmte, das Schließblech freigebende Endstellung hinaus in Motorantriebsrichtung antreibbar ist und im Verlaufe dieses Bewegungsabschnittes über einen schwenkbar am Schloßgehäuse gelagerten, mit der Falle gekuppelten Wechselhebel die Falle zurückzieht. Wird der Riegel nachfolgend wieder in die durch den Blockierriegel bestimmte Endstellung gebracht, ist das Türschloß aufgesperrt und kann ausschließlich über die Fallenfunktion geschlossen werden.The door lock should only be on the inside of the door, i.e. H. the protected side of the door, have a door handle coupled to the latch. The latch is actuated from the outside of the door by the electric motor driving the bolt. For this purpose, it is provided that the bolt can be driven in the motor drive direction beyond the end position determined by the locking bolt, releasing the striking plate and, in the course of this movement section, retracts the latch via a pivoting lever which is mounted on the lock housing and is coupled to the latch. If the bolt is subsequently returned to the end position determined by the blocking bolt, the door lock is unlocked and can only be closed using the latch function.

In Notfällen und bei einem Defekt der elektrischen Komponenten muß das Türschloß von der Türinnenseite her geöffnet werden können, und zwar auch dann, wenn der Riegel in das Schließblech eingeschlossen (ausgesperrt) ist. Dies läßt sich dadurch erreichen, daß der von der Türinnenseite her betätigbare Drücker über eine erste Drückernuß mit der Falle und über eine zweite Drückernuß mit dem Riegel für die gemeinsame Zurückziehbewegung der Falle und des Regels gekuppelt ist. Dies wird als ccAnti-Panikfunktionn des elektrischen bzw. elektronischen Schlosses bezeichnet. Von der Türinnenseite her können somit sowohl die Falle als auch der Riegel auf rein mechanischem Wege über den Türdrücker geöffnet werden. Von der Türaußenseite, d. h. der ungesicherten Seite der Tür her, wird das Türschloß ausschließlich über den Elektromotor geöffnet, der den Riegel und über einen Wechselhebel auch die Falle antreibt (bewegt).In emergencies and in the event of a defect in the electrical components, the door lock must be able to be opened from the inside of the door, even when the bolt is in the lock sheet is enclosed (locked out). This can be achieved in that the lever, which can be actuated from the inside of the door, is coupled to the latch via a first follower and to the bolt for the common retraction movement of the latch and the control via a second follower. This is known as the ccAnti panic function of the electrical or electronic lock. From the inside of the door, both the latch and the bolt can be opened in a purely mechanical way using the lever handle. From the outside of the door, ie the unsecured side of the door, the door lock is only opened by the electric motor, which also drives (moves) the latch and a change lever.

Der Schließzustand des Riegels kann überwacht werden. Die Überwachung läßt sich auch in Verbindung mit Alarmanlagen oder Zentralschließanlagen ausnutzen. Bei herkömmlichen Türschließanlagen wird der Schließzustand der Tür durch am Türrahmen einerseits und am Türblatt andererseits angebrachte Kontakte, insbesondere auch Reed-Kontakte überwacht. Diese Art der Überwachung ist jedoch unsicher und hängt von Bautoleranzen der Tür ab. Deshalb wird in der EP-A 0 235 703 vorgeschlagen, an dem in das Schließblech ausschließbaren Teil des Riegels und der Falle Magnetfeldsensoren anzubringen, die mit einem am Schließblech angeordneten Magnet zusammenwirken. Diese Art der Anordnung erleichtert die Zuführung elektrischer Leitungen zu den Magnetfeldsensoren und erlaubt die Überwachung ordnungsgemäßer Schließfunktionen des elektrischen Antriebs. Bei geöffneter Tür wird der Magnetfeldsensor des Riegels und der Falle auch dann nicht aktiviert, wenn der Riegel bzw. die Falle ordnungsgemäß aus dem Schloßgehäuse ausgeschlossen sind. Um diese Betriebssituation erfassen zu können, wird mittels einer zusätzlichen Magnetfeldsensor-Magnet-Anordnung die Position des Riegels relativ zum Schloßgehäuse erfaßt. Hierbei kann entweder die eingezogene Position oder die ausgeschlossene Position, ggf. auch beide Stellungen, überwacht werden. Aus der Kombination der von den Magnetfeldsensoren gelieferten Signale kann ein den Schließzustand und die Funktionsfähigkeit des Türschlosses repräsentierendes Signal abgeleitet werden. Bei den Magnetfeldsensoren handelt es sich bevorzugt um Hallschalter.The locking status of the bolt can be monitored. Monitoring can also be used in connection with alarm systems or central locking systems. In conventional door locking systems, the closed state of the door is monitored by contacts attached to the door frame on the one hand and to the door leaf on the other hand, in particular also reed contacts. However, this type of monitoring is unsafe and depends on the construction tolerances of the door. It is therefore proposed in EP-A 0 235 703 to attach magnetic field sensors to the part of the bolt and the latch which can be locked into the striking plate and which cooperate with a magnet arranged on the striking plate. This type of arrangement facilitates the supply of electrical lines to the magnetic field sensors and allows the proper closing functions of the electrical drive to be monitored. When the door is open, the bolt's magnetic field sensor and the latch are not activated even if the latch or latch is properly excluded from the lock housing. In order to be able to record this operating situation, the position of the bolt relative to the lock housing is recorded by means of an additional magnetic field sensor-magnet arrangement. Either the retracted position or the excluded position, possibly both positions, can be monitored. A signal representing the closed state and the functionality of the door lock can be derived from the combination of the signals supplied by the magnetic field sensors. The magnetic field sensors are preferably Hall switches.

Bei verklemmten Türen, durch Einbautoleranzen, Temperaturausdehnungen, kräftiges Zuschlagen von Türen und dergleichen, kann es zu erheblichen Belastungen der Falle und/oder des Riegels kommen. Auf die Falle können auch bei geschlossener Tür erhebliche Querbeanspruchungen einwirken, die ein Hineinbewegen der Falle in das Schloßgehäuse erschweren. Da die Baumaße von Einstecktürschlössern gemäß DIN 18 251 genormt sind, steht nicht unbegrenzter Raum für die Ausgestaltung des Türeingerichtes zur Verfügung. Auch die Unterbringung von zwei Drückemüssen zur Ermöglichung der Panikfunktion ist erschwert. Hinzu kommt, daß die Abmessungen der eingesetzten elektrischen bzw. elektronischen Bauteile in der Regel gering sind, so daß von diesen Antrieben nicht sehr große Antriebsleistungen übertragbar sind.If doors are jammed, due to installation tolerances, temperature expansion, vigorous slamming of doors and the like, the latch and / or bolt may be subjected to considerable loads. Considerable transverse stresses can act on the latch even when the door is closed, making it difficult to move the latch into the lock housing. Since the dimensions of mortise locks are standardized according to DIN 18 251, there is not unlimited space for the design of the door interior. It is also difficult to accommodate two pressures to enable the panic function. In addition, the dimensions of the electrical or electronic components used are generally small, so that very large drive powers cannot be transmitted from these drives.

Der Erfindung liegt die Aufgabe zugrunde, ein elektrisches bzw. elektronisches Türschloß, insbesondere Einstecktürschloß, der erfindungsgemäß vorausgesetzten Gattung dahingehend zu verbessem, daß Riegel und Falle motorisch in das Schloßgehäuse hineinbewegbar sind. Dabei soll die Aufgabe lösbar sein bei solchen elektrischen bzw. elektronischen Türschlössern, insbesondere Einstecktürschlössem, die die Abmaße nach DIN 18 251 aufweisen.The invention has for its object to improve an electrical or electronic door lock, in particular mortise lock, of the type required according to the invention in that latch and latch can be moved into the lock housing by a motor. The task should be solvable in such electrical or electronic door locks, especially mortise locks, which have the dimensions according to DIN 18 251.

Ausgehend von einem elektrisch bzw. elektronisch angetriebenen und/oder kontrollierten bzw. gesteuertem Türschloß, insbesondere Einstecktürschloß, für einen mit einem elektronischen Speicher für eine Schlüsselinformation versehenen elektronischen Schlüssel, mit einem Schloßgehäuse, einer zumindest von der Türinnenseite her mittels einer Handhabe betätigbaren, in ein Schließblech eingreifenden Falle, einem in das Schließblech ausschließbaren Riegel, einem elektrisch steuerbaren Schließmechanismus für den Riegel, einer Leseeinrichtung für die Schlüsselinformation des elektronischen Schlüssels und einer den Schließmechanismus abhängig von der gelesenen Schlüsselinformation steuerbaren Steuerschaltung, mit einem von einem Elektromotor angetriebenen Getriebe und einer den Riegel über das Getriebe mechanisch steuerbaren Sperrklinke, die den Riegel sowohl in der in das Schloßgehäuse vollständig eingeschlossenen, als auch in der aus dem Schloßgehäuse vollständig ausgeschlossenen Lage axial zur Entlastung der Elektromotor blockiert, wird diese Aufgabe dadurch gelöst, daß die Falle und der Riegel durch den Elektromotor in das Gehäuse hinein und der Riegel heraus antreibbar sind und daß das Übersetzungsverhältnis zwischen Elektromotor und Falle einerseits und Elektromotor und Riegel andererseits während der Ein- und Ausschlußbewegung von Falle und Riegel veränderbar ist,Starting from an electrically or electronically driven and / or controlled or controlled door lock, in particular a plug-in door lock, for an electronic key provided with an electronic memory for key information, with a lock housing, which can be actuated at least from the inside of the door by means of a handle Strike plate engaging latch, a bolt that can be locked into the strike plate, an electrically controllable locking mechanism for the bolt, a reading device for the key information of the electronic key and a control circuit that can control the locking mechanism depending on the key information read, with a gear driven by an electric motor and one for the bolt Mechanically controllable pawl via the gearbox, which completely locks the bolt both in the lock housing and in the lock housing from the a Us closed position axially blocked to relieve the electric motor, this problem is solved in that the latch and the bolt can be driven by the electric motor into the housing and the bolt out and that the transmission ratio between the electric motor and latch on the one hand and the electric motor and bolt on the other during Inclusion and exclusion movement of latch and bolt can be changed

Durch die besondere Ausgestaltung des erfindungsgemäßen Einstecktürschlosses wird sichergestellt, daß Falle und Riegel motorisch in das Schloßgehäuse hineinbewegbar und der Riegel motorisch aus dem Schloßgehäuse herausbewegbar sind. Erfindungsgemäß wird durch die besondere konstruktive Ausgestaltung des Schloßeingerichtes sichergestellt, daß auch die Schloßfalle bei relativ großer Querbeanspruchung, beispielsweise bei Kraftschluß an einem Schließblech, ohne weiteres motorisch in den Schloßkasten hineinbewegt werden kann.The special design of the plug-in door lock according to the invention ensures that the latch and bolt can be moved into the lock housing by motor and the bolt can be moved out of the lock housing by motor. According to the invention, the special structural design of the lock device ensures that the lock latch can also be easily moved into the lock case by a motor in the case of a relatively large transverse load, for example in the event of a frictional connection to a strike plate.

Außerdem ermöglicht die Ausgestaltung und Anordnung des Schloßeingerichtes es bei dem erfindungemäßen Einstecktürschloß, das die Panikfunktion bei nur einer Schloßnuß gewährleistet ist.In addition, the design and arrangement of the lock mechanism makes it possible with the inventive insert door lock that the panic function is ensured with only one lock nut.

Alles in allem baut ein erfindungsgemäßes Einstecktürschloß außerordentlich kompakt, so daß sich die Erfindung bei Einstecktürschlössern nach DIN 18 251 verwirklichen läßt,All in all, an insert door lock according to the invention is extremely compact, so that the invention can be implemented with insert door locks according to DIN 18 251,

Bei dem erfindungsgemäßen Einstecktürschloß treibt der Elektromotor beim Hineinbewegen von Falle und Riegel zunächst den Schloßriegel mit einer anderen Übersetzung an, als die Falle bei deren Hineinbewegen in das Schloßgehäuse. Erfindungsgemäß wird die Übersetzung kurz vor oder unmittelbar bei Beginn der motorischen Hineinbewegung der Falle so umgesteuert oder verändert, daß mit dem gleichen Motor relaktiv große Kräfte auf die dafür vorgesehenen Schloßeingerichteteile übertragen werden, so daß selbst bei einem Anliegen der Falle unter Spannung oder bei relativ großem Kraftschluß am Schließblech der motorische Antrieb im Schloßgehäuse nicht überfordert ist (Patentanspruch 2).In the mortise lock according to the invention, when the latch and bolt are moved in, the electric motor first drives the latch bolt with a different ratio than the latch in the latter Move into the lock housing. According to the invention, the translation is reversed or changed shortly before or immediately at the start of the motor-driven movement of the trap in such a way that relatively large forces are transmitted to the lock components provided for this purpose with the same motor, so that even if the trap is under tension or relatively large Non-positive connection on the striking plate the motor drive in the lock housing is not overwhelmed (claim 2).

In Patentanspruch 3 ist eine vorteilhafte Ausführungsform der Erfindung beschrieben. Bei dieser gelangen nacheinander Zahnsegmente an unterschiedlichen Hebelarmen zur Einwirkung, derart, daß der Schloßriegel mit einem relativ kürzeren Hebelarm in den Schloßkasten hineinbewegt wird, während die Falle mit einem relativ größeren Hebelarm durch den gleichen motorischen Antrieb in den Schloßkasten hineinbewegt wird, wobei die Hebel an ein und demselben Teil funktionell einstückig oder materialmäßig einstückig angeordnet sein können.An advantageous embodiment of the invention is described in claim 3. In this successive tooth segments come into effect on different lever arms, such that the lock bolt is moved into the lock case with a relatively shorter lever arm, while the latch with a relatively larger lever arm is moved into the lock case by the same motor drive, with the levers on one and the same part can be arranged functionally in one piece or materially in one piece.

Der gleiche Hebel, an dem die unterschiedlichen Hebelarme zum Antrieb von Riegel und Falle angeordnet sind, kann auch gleichzeitig zur Übertragung der Anti-Panik-Funktion des Einstecktürschlosses gemäß der Erfindung dienen. Zu diesem Zweck ist die Drückemuß z. B. am Umfang mit einem Nocken versehen, der mit einer Kurve zusammenwirkt, die ein materialmäßig einstückiges Teil der beiden Hebel bildet. Auf diese Weise gelangt man zu einer besonders kompakten Bauweise des Schloßeingerichtes. Zwei Drückemüsse mit demgemäß zwei Drückerdomen brauchen somit nicht vorgesehen zu werden (Patentanspruch 4).The same lever on which the different lever arms for driving the bolt and latch are arranged can also serve at the same time to transmit the anti-panic function of the mortise lock according to the invention. For this purpose, the pressure is z. B. provided on the circumference with a cam which interacts with a curve which forms a materially integral part of the two levers. In this way you get a particularly compact design of the castle interior. Two push buttons with two push domes accordingly do not need to be provided (claim 4).

  • Figure 1 shows a mortise lock according to the invention in plan view, namely in the so-called "anti-panic function position".
  • FIG. 2 shows the insert door lock shown in FIG. 1, but the latch and bolt have been moved into the lock housing by a motor;

Die Zeichnung veranschaulicht ein Einstecktürschloß, dessen Abmessungen nach DIN 18 251 ausgeführt wurden. In einem Schloßgehäuse 1, von dem in den Zeichnungsfiguren in der Draufsicht ein Schloßblech 2 erkennbar ist, sind eine Falle 3 und ein Riegel 4 in Richtung deren Längsmittenachse, also achsial verschieblich, um jeweils ein begrenztes Maß geführt. Die Falle 3 ist in einer Öffnung 5 einer Stulpe 6 des Schloßgehäuses 1 geführt, wobei eine gehäusefeste Gewindebuchse 7 durch ein Langloch 8 eines Fallenschwanzes 9. hindurchgreift. Eine Fallenfeder 10 spannt die Falle 3 in Ausschließrichtung vor, derart, daß die Falle 3 ständig die Tendenz hat, sich mit ihrem Fallenkopf 11 aus der Öffnung 5 der Stulpe 6 herauszubewegen. Die Fallenfeder 10 ist bei der dargestellten Ausführungsform als Spiralfeder ausgebildet und mit ihrem Wickelauge 12 um einen gehäusefesten Vierkantdorn 13 gelagert, derart, daß ein Federschenkel 14 annähernd parallel zur Innenseite der Stulpe 6 verlaufend sich mit einem abgekröpften Längenabschnitt gegen eine Innenwand 15 des Fallenkopfes 11 federnd abstützt. Ein anderer Federschenkel 16 dient als Schlußfeder und belastet mit einem abgekröpften Längenabschnitt eine Sperrklinke 17 in Richtung auf den Riegel 4. Die Funktion der Sperrklinke 17 wird noch weiter unten beschrieben.The drawing illustrates a mortise lock, the dimensions of which were carried out in accordance with DIN 18 251. In a lock housing 1, of which a lock plate 2 can be seen in plan view in the drawing figures, a latch 3 and a bolt 4 are guided in the direction of their longitudinal center axis, that is to say axially displaceable, by a limited amount in each case. The latch 3 is guided in an opening 5 of a cuff 6 of the lock housing 1, a threaded bush 7 fixed to the housing engaging through an elongated hole 8 of a latch tail 9. A latch spring 10 biases the latch 3 in the exclusion direction, such that the latch 3 has the tendency to move out of the opening 5 of the cuff 6 with its latch head 11. The latch spring 10 is formed in the illustrated embodiment as a spiral spring and mounted with its winding eye 12 around a square mandrel 13 fixed to the housing, such that a spring leg 14 extends approximately parallel to the inside of the cuff 6 with a cranked length section resiliently against an inner wall 15 of the latch head 11 supports. Another spring leg 16 serves as a closing spring and loads a pawl 17 in the direction of the bolt 4 with a bent length section. The function of the pawl 17 is described further below.

Mit dem Bezugszeichen 18 ist eine Nuß bezeichnet, deren Nußhebel 20 mit einem ballig ausgebildeten Teil 21 gegen einen vom Fallenschwanz 9 normal (rechtwinklig) verlaufenden Vorsprung 22 einwirkt. Die Nuß 18 dient auf der gesicherten Türinnenseite zur Aufnahme eines nicht dargestellten Drückerdomes, der in der Vierkantöffnung 23 angeordnet wird. Mit 19 ist eine Konterfeder bezeichnet, die über einen Steg 66 die Nuß 18 vorspannt.The reference numeral 18 designates a nut, the nut lever 20 of which acts with a spherically shaped part 21 against a projection 22 which runs normally (at right angles) from the latch tail 9. The nut 18 is used on the secured inside of the door to receive a pusher dome, not shown, which is arranged in the square opening 23. With 19 a counter spring is designated, which biases the nut 18 via a web 66.

Gegenüberliegend zum Nußhebel 20 ist ein weiterer Hebel 24 angeordnet, der an seinem freien Ende auf einem einstückigen Ansatzdom 25 eine Rolle 26 trägt, die an einer Kurvenbahn 27 eines Hebels 28 kraftschlüssig anliegt. Über den nicht dargestellten Drückerdom und die Nuß 28 läßt sich somit die Falle 3 gegn die Rückstellkraft der Fallenfeder 10 in das Schloßgehäuse 1 hineinbewegen. Die entsprechenden Stellungen der Schloßeingerichteteile in dieser Stellung ergeben sich aus Fig. 1.Opposite to the nut lever 20, a further lever 24 is arranged, which carries at its free end on a one-piece extension dome 25 a roller 26 which bears frictionally against a cam track 27 of a lever 28. The latch 3 against the restoring force of the latch spring 10 can thus be moved into the lock housing 1 via the handle dome (not shown) and the nut 28. The corresponding positions of the lock fitting parts in this position are shown in FIG. 1.

Auf der Türaußenseite ist bei einem erfindungsgemäßen Einstecktürschloß normalerweise keine Handhabe Drückerdom, (Olive, Drehknopf, Türklinke o. dgl.) vorgesehen. Von der Außenseite werden somit sowohl die Falle 3 als auch der Riegel 4 von einem Elektromotor 29 geöffnet, der über eine Steuerschaltung 30 abhängig von einer Schlüsselwortinformation gesteuert wird, die eine elektronische Leseeinrichtung 31 an einem in einen Schlüsselkanal 32 eingeführten elektronischen Schlüssel 33 liest. Stimmt die gelesene Schlüsselinformation mit einer in der Steuerschaltung 30 gespeicherten Information überein, so zieht der Elektromotor 29 den Riegel 4 und die Falle 3 in das Schloßgehäuse 1 hinein (Fig. 3).In the case of a plug-in door lock according to the invention, there is normally no handle dome (olive, rotary knob, doorknob or the like) provided on the outside of the door. Both the latch 3 and the bolt 4 are thus opened from the outside by an electric motor 29, which is controlled via a control circuit 30 as a function of key word information which an electronic reading device 31 reads on an electronic key 33 inserted into a key channel 32. If the key information read matches information stored in the control circuit 30, the electric motor 29 pulls the bolt 4 and the latch 3 into the lock housing 1 (FIG. 3).

Die Stromversorgung der Steuerschaltung 30, des Elektromotors 29 und der Leseeinrichtung 31 erfolgt über eine Leitung 34 aus einem zentralen Netzgerät 35, welches für den Notbetrieb mit einem Akkumulator versehen ist.The power supply to the control circuit 30, the electric motor 29 and the reading device 31 takes place via a line 34 from a central power supply unit 35, which is provided with an accumulator for emergency operation.

Der Riegel 4 ist in einer Öffnung 36 der Stulpe 6 in seiner Längsachsrichtung geführt. Zu diesem Zweck besitzt der Riegelschwanz ein Langloch 37, in das ein gehäusefester Doppeldom 38 eingreift. Der Doppeldom 38 besitzt im Abstand von der einen Gehäusewand eine Verjüngung, so daß der Riegelschwanz 39 mit Spaltabstand zu dem betreffenden Schloßblech 2 des Schloßgehäuses 1 geführt istThe bolt 4 is guided in an opening 36 of the cuff 6 in its longitudinal axis direction. For this purpose, the bolt tail has an elongated hole 37 into which a double dome 38 fixed to the housing engages. The double dome 38 has a taper at a distance from the one housing wall, so that the bolt tail 39 is guided with a gap distance to the relevant lock plate 2 of the lock housing 1

Mit 40 ist ebenfalls ein Doppeldom bezeichnet, der ebenfalls im Abstand von der einen Schloßgehäusewand verjüngt ausgebildet ist. Auf dem verjüngten Abschnitt des Doppeldornes 40 ist mit Spaltabstand zum Schloßgehäuse 1 der Hebel 28 um ein begrenztes Winkelmaß parallel zu dem aus der Zeichnung ersichtlichen Schloßblech 2 (Schloßgehäuseboden) schwenkeweglich angeordnet. Dieser Hebel 28 übergreift den Riegelschwanz 39 und die Sperrklinke 17 und liegt auf dem Riegelschwanz 39 auf. Der Hebel 28 weist ein Langloch 43 auf, durch das ein normal zur Oberfläche des Riegelschwanzes 39 verlaufender Ansatzdom 44 mit Spielpassung eingreift.40 also designates a double dome, which is also at a distance from one of the castle ridges house wall is tapered. On the tapered section of the double mandrel 40, the lever 28 is arranged with a gap distance to the lock housing 1 by a limited angular dimension parallel to the lock plate 2 (lock housing base) shown in the drawing. This lever 28 engages over the bolt tail 39 and the pawl 17 and rests on the bolt tail 39. The lever 28 has an elongated hole 43 through which a shoulder dome 44 which runs normal to the surface of the bolt tail 39 engages with a clearance fit.

Auf der dem Riegelschwanz 39 zugekehrten Seite trägt der Hebel 28 zwei Ansatzdome 45 und 46, die einstückig mit dem Hebel 28 ausgebildet sind, beispielsweise eingelassene oder eingenietete Paßstifte darstellen. Die Ansatzdorne 45 und 46 sind mit Winkelabstand zueinander angeordnet und liegen auf einem Kreisbogen. Beide Ansatzdome 45 und 46 berühren die kurvenförmige Außenkontur 47 der Sperrklinke 17.On the side facing the bolt tail 39, the lever 28 carries two attachment domes 45 and 46, which are formed in one piece with the lever 28, for example, recessed or riveted dowel pins. The shoulder mandrels 45 and 46 are arranged at an angular distance from one another and lie on a circular arc. Both attachment domes 45 and 46 touch the curved outer contour 47 of the pawl 17.

Wie die Zeichnung erkennen läßt, weist der Hebel 28 an seiner dem Doppeldorn 40 abgekehrten Seite zwei sektorförmige Zahnkränze 48 und 49 auf. Der Zahnsektor 48 besitzt in Bezug auf den als feste Achse dienenden Doppeldom 40 den Hebelarm M, während der Zahnsektor 49 in Bezug auf den Doppeldom 40 den Hebelarm L aufweist. Der Hebelarm M ist somit um das Maß A größer als der Hebelarm L. Folglich wirkt eine an dem Zahnsektor 48 angreifende Antriebskraft an eine um das Maß M vergrößerten Hebelarm, so daß mit der gleichen Antriebsleistung beim Angriff an den Zahnkranzsektor 48 ein vergrößertes Moment über den Hebelarm M übertragen werden kann.As can be seen in the drawing, the lever 28 has two sector-shaped toothed rings 48 and 49 on its side facing away from the double mandrel 40. The tooth sector 48 has the lever arm M with respect to the double dome 40 serving as a fixed axis, while the tooth sector 49 has the lever arm L with respect to the double dome 40. The lever arm M is thus larger than the lever arm L by the dimension A. Consequently, a driving force acting on the toothed sector 48 acts on a lever arm enlarged by the dimension M, so that with the same drive power when attacking the ring gear sector 48, an increased torque over the Lever arm M can be transferred.

Sowohl in der ausgeschlossenen Position (Fig. 4), als auch in der eingezogenen Position (Fig. 3) wird der Riegel 4 durch die Sperrklink 17 gegen Krafteinwirkung von außen blockfiert und der Elektromotor 29 geschützt. Bei in eingeschlossenem Zustand blockierten Riegel 4 verhindert die Sperrklinke 17 ein Herausbewegen des Riegels 4, z. B. beim Zuschlagen der Tür. Die Sperrklinke 17 ist ebenfalls um einen Ansatzdorn 50 um ein begrenztes Maß schwenkbeweglich im Abstand vom Schloßgehäuseboden 2 angeordnet. Zu diesem Zweck ist der im Schloßgehäuseboden 2 befestigter Ansatzdom 50 im Abstand vom Schloßgehäuseboden 2 im Durchmesser verjüngt. Auf diesem verjüngten Längenabschnitt ist die Sperrklinke 17 schwenkbeweglich gelagert. Die Sperrklinke 17 ist ständig durch den Federschenkel 16 in BlockierschwenksteIlung belastet, also in Eingriffsrichtung vorgespannt. Die Sperrklinke 17 hat einen ersten und einen zweiten Verriegelungszahn 51 und 52. Der Verriegelungszahn 52 greift hinter eine Schulter 53 am Riegelschwanz 39, während der Verriegelungszahn 51 hinter eine Schulter 54 des Riegelschwanzes 39 greift. Die erste Stellung entspricht der Lage des Riegels im Schloßgehäuse, also der vollständig in das Schloßgehäuse eingezogenen Lage (Fig. 3), und die zweite Position der Stellung, in der der Riegel 4 aus dem Schloßgehäuse 1 vollständig ausgeschlossen ist (Fig. 4). Die Sperrklinke 17 taucht mit einem Hebelteil 55 in eine Aussparung 56 des Riegelschwanzes 39, wobei sie eine Schwenkbewegung um den Ansatzdorn 50 durchführt. Dies geschieht dadurch, daß die am Hebel 28 befestigten Ansatzdorne 45 und 46 beim Verschwenken des Hebels 28 gegen die Außenkontur 47 einwirken und dabei die Sperrklinke 17 gegen die Rückstellkraft des Federschenkels 16 - in der der Zeichnungsebene nach oben - schwenken. Dies geschieht wiederum dadurch, daß der Elektromotor 29 entsprechend angetrieben wird. Eine Achse 57 ragt aus dem Motorgehäuse heraus und weist etwa im mittleren Längenbereich eine Schnecke 58 auf, die mit einem Schneckenrad 59 kämmt, das um eine Achse 60, die im Schloßlech 2 fest angeordnet ist und normal (rechtwinklig) zu diesem verläuft, hin-und herdrehbar ist. Mit dem Schneckenrad 59 ist ein Stirnrad 61 getrieblich gekuppelt, das bei der dargestellten Ausführungsform entsprechend dem Maß A exzentrisch ausgebildet ist, so daß nacheinander entweder der Zahnkranzsektor 48 oder nach einem gewissen Drehwinkel der Zahnkranzsektor 49 mit dem Stirnrad 61 kämmt, was eine entsprechende Schwenkbewegung des Hebels 28 zur Folge hat. Dabei ist eine solche Anordnung getroffen worden, daß der Riegel 4 über den Zahnkranzsektor 49 ein-und ausgeschlossen (in das Gehäuse 1 hinein oder aus diesem herausbewegt) wird, während das Hineinbewegen der Falle 3 in bzw. aus dem Schloßgehäuse 1 über den Zahnkranzsektor 48 motorisch geschieht, da hierbei der größerer Hebelarm M zur Verfügung steht. Auf diese Weise ist es möglich, auch erhebliche Kräfte, die möglicherweise durch Reibschluß o. dgl. auf den Fallenkopf 11 einwirken, motorisch zu überwinden. Die Anti-Panik-Funktion ist dadurch sichergestellt, daß ein in der Vierkantöffnung 23 befindliche Drückerdom nach unten gedrückt wird, wodurch über den Hebel 24 und die Rolle 26 der Hebel 28 so verschwenkt wird, wie dies aus Fig. 1 ersichtlich ist. Dabei werden sowohl die Falle 3 als auch der Riegel 4 in das Schloßgehäuse 1 hineinbewegt. Der Elektromotor 29 oder das Stirnrad 61 werden dabei nicht bewegt, da diese stets so gesteuert werden, daß sie in Ruhestellung aus dem Eingriffsbereich der Zahnkranzsektoren 48 bzw. 49 kommen. Der Elektromotor 29 bewirkt somit nicht nur das Hineinbewegen von Falle 3 und Riegel 4 in das Schloßgehäuse 1, sondern auch das Herausbewegung des Riegels 4 aus dem Schloßgehäuse 1. Bei der Anti-Panik-Funktion hebt der Ansatzdorn 46 die Sperrklinke 17 an, und der Riegel 4 wird durch die Kulissenverbindung 43, 44 in das Schloßgehäuse 1 hineinbewegt.Both in the closed position (Fig. 4) and in the retracted position (Fig. 3), the bolt 4 is blocked by the pawl 17 against external forces and the electric motor 29 is protected. When the bolt 4 is locked in the locked state, the pawl 17 prevents the bolt 4 from being moved out, for. B. when slamming the door. The pawl 17 is also arranged around an extension mandrel 50 to be pivotable by a limited amount at a distance from the lock housing base 2. For this purpose, the attachment dome 50 fastened in the lock housing base 2 is tapered in diameter at a distance from the lock housing base 2. The pawl 17 is pivotally mounted on this tapered length section. The pawl 17 is constantly loaded by the spring leg 16 in the blocking pivot direction, that is to say it is prestressed in the direction of engagement. The pawl 17 has a first and a second locking tooth 51 and 52. The locking tooth 52 engages behind a shoulder 53 on the locking tail 39, while the locking tooth 51 engages behind a shoulder 54 of the locking tail 39. The first position corresponds to the position of the bolt in the lock housing, i.e. the position completely retracted into the lock housing (FIG. 3), and the second position corresponds to the position in which the bolt 4 is completely excluded from the lock housing 1 (FIG. 4). The pawl 17 dips with a lever part 55 into a recess 56 of the bolt tail 39, wherein it carries out a pivoting movement around the shoulder mandrel 50. This is done in that the attachment pins 45 and 46 attached to the lever 28 act when pivoting the lever 28 against the outer contour 47 and thereby the pawl 17 against the restoring force of the spring leg 16 - in the plane of the drawing upwards - pivot. This in turn happens in that the electric motor 29 is driven accordingly. An axis 57 protrudes from the motor housing and has a worm 58, which meshes with a worm wheel 59, which meshes with an worm wheel 59, which extends around an axis 60, which is fixedly arranged in the lock plate 2 and runs normal (at right angles) to it. and can be turned. With the worm gear 59, a spur gear 61 is coupled, which in the illustrated embodiment is designed eccentrically in accordance with dimension A, so that either the sprocket sector 48 or after a certain angle of rotation, the sprocket sector 49 meshes with the spur gear 61, which results in a corresponding pivoting movement of the Lever 28 has the consequence. In this case, such an arrangement has been made that the bolt 4 is locked in and out (moved into or out of the housing 1) via the ring gear sector 49, while the latch 3 is moved into or out of the lock housing 1 via the ring gear sector 48 happens by motor since the larger lever arm M is available. In this way it is possible to overcome considerable forces which may act on the latch head 11 by frictional engagement or the like. The anti-panic function is ensured in that a pusher dome located in the square opening 23 is pressed down, as a result of which the lever 28 is pivoted via the lever 24 and the roller 26, as can be seen from FIG. 1. Both the latch 3 and the bolt 4 are moved into the lock housing 1. The electric motor 29 or the spur gear 61 are not moved because they are always controlled so that they come out of the engagement area of the ring gear sectors 48 and 49 in the rest position. The electric motor 29 thus causes not only the latch 3 and bolt 4 to be moved into the lock housing 1, but also the movement of the bolt 4 out of the lock housing 1. In the anti-panic function, the shoulder pin 46 lifts the pawl 17, and that Bolt 4 is moved through the link connection 43, 44 into the lock housing 1.

Die Achse 57 des Elektromotors 29 ist in einem Schneckenlager 65 gelagert. Dieses Schneckenlager 65 kann aus einer normal (rechtwinklig) zu dem Schloßblech 2 verlaufenden und kraftschlüssig sowohl im Schloßblech 2 als auch in der nicht dargestellten Schloßdecke befestigten Flacheisen bestehen. Dadurch wird die Achse 57 des Elektromotors 29 sowohl radial als auch axial entlastet.The axis 57 of the electric motor 29 is mounted in a worm bearing 65. This screw bearing 65 can consist of a normal (at right angles) to the lock plate 2 and non-positively attached flat iron both in the lock plate 2 and in the lock cover, not shown. As a result, the axis 57 of the electric motor 29 is relieved both radially and axially.

Die Position, in welcher der betreffende Verriegelungszahn 52 den Riegel 4 in der offenen Position verriegelt, wird sowohl vor als auch nach Durchlaufen der Fallenrückzugsposition durchlaufen. Zweckmäßigerweise wird der Elektromotor 29 in der in Drehrichtung nachfolgenden Position angehalten, um durch einmaliges Betätigen des Schlüssels 33 die Falle 3 kurzzeitig zu öffnen und nachfolgend den Riegel 4 geöffnet zu halten. Die Fallenöffnungszeit kann durch Drehverzögerung im Betriebszustand erhöht werden.The position in which the locking tooth 52 in question locks the bolt 4 in the open position is passed both before and after passing through the latch retraction position. Advantageously, the electric motor 29 in the stopped in the direction of rotation following position in order to briefly open the latch 3 by pressing the key 33 once and subsequently keep the bolt 4 open. The trap opening time can be increased in the operating state by turning delay.

Das erfindungsgemäße, elektrisch bzw. elektronisch angetriebene und/oder kontrollierte bzw. gesteuerte Türschloß ermöglicht eine Überwachung des Schließzustandes der Tür und eine Funktionskontrolle des Schlosses. Es eignet sich deshalb insbesondere für Alarmanlagen, speziell Alarmanlagen mit Blockschloßfunktio und für Schließanlagen mit zentraler Schließfunktion. In dem in das Schließblech eindringenden Teil sowohl der Falle 3 als auch des Riegels 4 sind Hallschalter eingebaut, die auf Magnete in den zugeordneten Eingriffsöffnungen des nicht dargestellten Schließbleches ansprechen. Dies ist in der Zeichnung nicht veranschaulicht. Die Hallschalter liefern Signale an nicht näher dargestellte Überwachungsschaltungen, wenn die Falle 3 und der Riegel 4 vollständig in das Schließblech eingreifen.The electrically or electronically driven and / or controlled or controlled door lock according to the invention enables monitoring of the closed state of the door and a functional check of the lock. It is therefore particularly suitable for alarm systems, especially alarm systems with a block lock function and for locking systems with a central locking function. In the part penetrating into the striking plate of both the latch 3 and the bolt 4, Hall switches are installed which respond to magnets in the associated engagement openings of the striking plate, not shown. This is not illustrated in the drawing. The Hall switches deliver signals to monitoring circuits, not shown, when the latch 3 and the bolt 4 fully engage in the striking plate.

Die Hallschalter liefern jedoch lediglich Informationen über den Schließzustand der Tür, erlauben aber keine vollständigen Rückschlüsse auf die Funktionsfähigkeit des Türschlosses. An dem Riegel 4 ist deshalb ein weiterer, nicht dargestellter Magnet angebracht, dessen Position in einem in dem Schloßgehäuse 1 angeordneten Hallschalter erfaßt wird. Der Hallschalter spricht an, wenn der Riegel 4 vollständig ausgeschlossen ist. Aus den Signalen der Hallschalter lassen sich damit Informationen ableiten, ob der Riegel 4 bei geöffneter oder geschlossener Tür ausgeschlossen ist. Schließlich ist ein dritter Hallschalter in dem Schloßgehäuse 1 vorgesehen, der in der geöffneten Stellung des Riegels 4 auf einen Magnet des Riegels 4 anspricht. Der Hallschalter kann bei Invertierung seines Ausgangssignals die Funktion des Hallschalters übernehmen, so daß ggf. einer der beiden Hallschalter entfallen kann. Die Überwachung beider Schließpositionen des Riegels 4 erhöht die SchlieBsicherheit.However, the Hall switches only provide information about the closed state of the door, but do not allow complete conclusions to be drawn about the functionality of the door lock. A further magnet, not shown, is therefore attached to the bolt 4, the position of which is detected in a Hall switch arranged in the lock housing 1. The Hall switch responds when the bolt 4 is completely excluded. From the signals of the Hall switch, information can be derived as to whether the bolt 4 is excluded when the door is open or closed. Finally, a third Hall switch is provided in the lock housing 1, which responds to a magnet of the bolt 4 in the open position of the bolt 4. The Hall switch can take over the function of the Hall switch when its output signal is inverted, so that one of the two Hall switches may be omitted. Monitoring both locking positions of bolt 4 increases locking security.
