Abstract

The drive shaft (11) transmitting rotary motion to the lock is manually rotatable using the knob (8) in which the motor (5) and gearing (6) are installed coaxially. Slip-ring contacts (10), magnet connections and contacts of a microswitch (14) are all wired to an electronic controller preferably in the cavity of the cover plate (1). The motor rotates with the knob so that manual torque is transmitted to the shaft and rotatability of the motor casing for motorised drive is inhibited. For torque transmission from the casing to the shaft, in manual operation, the gearing is held approximately at a standstill.

Description

Die Erfindung betrifft eine Antriebsvorrichtung gemäß Gattungsbegriff des Anspruches 1.The invention relates to a drive device according to the preamble of claim 1.

Eine derartige Antriebsvorrichtung wird vom deutschen Patent 36 06 531 gezeigt. Rückwärtig eines Beschlagschildes ragt dort eine drehbare Abtriebswelle in den Kernbereich eines Schließzylinders. Die Abtriebswelle setzt sich fort bis zur Beschlagsfrontseite und ist dort drehfest mit einer Drehhandhabe verbunden. Das Beschlagschild weist einen elektrisch betriebenen Motor auf, welcher über ein Untersetzungsgetriebe und einen Riemenantrieb auf die Abtriebswelle wirkt.Such a drive device is shown by German Patent 36 06 531. At the rear of a fitting plate, a rotatable output shaft projects into the core area of a locking cylinder. The output shaft continues to the front of the fitting and is connected there in a rotationally fixed manner with a turning handle. The fitting plate has an electrically operated motor which acts on the output shaft via a reduction gear and a belt drive.

Der Erfindung liegt die Aufgabe zugrunde, einen derartigen Motorbeschlag handhabungstechnisch zu verbessern und fertigungstechnisch zu vereinfachen.The invention has for its object to improve such a motor fitting handling technology and simplify manufacturing technology.

Gelöst wird die Aufgabe in der in den Ansprüchen angegebenen Erfindung.The object is achieved in the invention specified in the claims.

Zufolge der erfindungsgemäßen Ausgestaltung ist eine einfach zu fertigende Vorrichtung gegeben. Die Vorrichtung ist einfach zu handhaben. Der Getriebemotor sitzt in der Drehhandhabe. Eine Betätigung der Drehhandhabe bewirkt daher eine Rotation des Motorgehäuses. Da Mittel vorgesehen sind, die das Getriebe im Stillstand oder im annähernden Stillstand halten, wird die auf das Motorgehäuse ausgeübte Drehbewegung auf die Getriebeabtriebswelle übertragen. Bei den zur Schließbetätigung üblichen Drehmomenten wirkt das Getriebe technisch wie ein starres Übertragungsglied. Die Vorrichtung hat die Wirkung, als wenn die Abtriebswelle im wesentlichen starr mit der Drehhandhabe verbunden wäre, wenn der Motor nicht angetrieben wird. In dieser ersten, manuellen Betriebsweise kann die auf die Drehhandhabe ausgeübte Drehbewegung unmittelbar auf die Abtriebswelle und damit auf das Schloß bzw. den Schließzylinder übertragen werden. Soll die Antriebsvorrichtung in ihrer zweiten Betriebsart verwendet werden, so wird die Drehbarkeit der Drehhandhabe blockiert. Eine elektrische Beaufschlagung des Motors führt zu dessen Drehung. Die Drehung der Motorachse wird über das Untersetzungsgetriebe auf die Abtriebswelle übertragen, so daß eine motorbetätigbare Schloß- oder Schließzylinderbetätigung möglich ist. Die bevorzugte Ausgestaltung der Antriebsvorrichtung sieht vor, daß die Getriebeabtriebswelle gleichzeitig die Abtriebswelle der Vorrichtung ausbildet und daß diese Welle koaxial zur Betätigungshandhabe ausgerichtet ist. Hierdurch ist eine äußerst reibungsarme manuelle Betätigung gegeben. Eine Weiterbildung der Erfindung sieht vor, daß die Abtriebswelle eine Kontaktscheibe trägt, welche drehfest mit der Welle verbunden ist. Die Kontaktscheibe wirkt mit einem Positionsschalter oder einem Positionsmelder zusammen. Bevorzugt weist die Kontaktscheibe einen Nocken auf, welcher mit einem Mikroschalter zusammenwirkt. Wird der Mikroschalter von dem Nocken beaufschlagt, so wird eine die Antriebsvorrichtung steuernde elektronische Steuerung davon unterrichtet, daß eine definierte Winkelstellung der Abtriebswelle vorliegt. Diese definierte Winkelstellung ist bevorzugt die Schlüsselabzugstellung eines Schließzylinders, wenn die Antriebsvorrichtung auf einen Schließzylinder wirkt. Der Getriebestillstand bei der manuellen Betätigung wird bevorzugt über eine Selbsthemmung des Untersetzungsgetriebes erzielt. Eine weitere vorteilhafte Weiterbildung sieht vor, daß der Motor im nicht-motorbetriebenen Zustand über einen Widerstand kurzgeschlossen ist. Hierdurch kann das Mitnahme-Drehmoment von Drehhandhabe auf Abtriebswelle eingestellt werden. Die im Motor auftretenden Kurzschlußströme zufolge Wirbelstromerregung können durch die Bemessung des Widerstandes eingestellt werden. Die Blockierung der Drehhandhabe zur motorischen Drehung der Abtriebswelle erfolgt bevorzugt durch ein elektromagnetisches Blockierelement. Vorzugsweise wird hierzu ein Hubmagnet verwendet, dessen axial verlagerbarer Anker mit einer Außenverzahnung der Drehhandhabe zusammenwirkt. Wird bspw. der motorbetriebene Antrieb gewünscht, so wird der Motor strombeaufschlagt. Gleichzeitig damit erfolgt eine Strombeaufschlagung des Hubmagneten. Der Anker des Hubmagneten verlagert sich aus seiner zurückgezogenen Stellung in eine Vorschubstellung und greift mit dem Kopfbereich seines Ankers in eine Zahnlücke der Außenverzahnung ein, so daß die Drehbarkeit der Drehhandhabe blockiert ist. Sodann bewirkt die Drehbewegung der Motorachse eine Drehbewegung der Abtriebswelle. Die Drehhandhabe ist bevorzugt als Hülse ausgebildet, um den Motor und das Getriebe aufzunehmen. Getriebe und Motor liegen bevorzugt axial hintereinander. Auf der Hülsenaußenwandung sind zwei Kontaktringe angebracht, welche mit beschlagschildfesten Schleifern abgegriffen werden.As a result of the configuration according to the invention, an easy-to-manufacture device is provided. The device is easy to use. The geared motor sits in the turning handle. Actuation of the rotary handle therefore causes the motor housing to rotate. Since means are provided which keep the gearbox at a standstill or at a standstill, the rotary movement exerted on the motor housing is transmitted to the gearbox output shaft. At the torques customary for closing actuation, the gearbox acts technically like a rigid transmission element. The device acts as if the output shaft essentially would be rigidly connected to the rotary handle if the motor is not driven. In this first, manual mode of operation, the rotary movement exerted on the turning handle can be transmitted directly to the output shaft and thus to the lock or the lock cylinder. If the drive device is to be used in its second operating mode, the rotatability of the turning handle is blocked. An electrical load on the motor causes it to rotate. The rotation of the motor axis is transmitted to the output shaft via the reduction gear, so that a motor-operated lock or lock cylinder actuation is possible. The preferred embodiment of the drive device provides that the transmission output shaft simultaneously forms the output shaft of the device and that this shaft is aligned coaxially with the actuating handle. This results in an extremely low-friction manual operation. A further development of the invention provides that the output shaft carries a contact disk which is connected to the shaft in a rotationally fixed manner. The contact disk interacts with a position switch or a position detector. The contact disk preferably has a cam which interacts with a microswitch. If the microswitch is acted upon by the cam, an electronic control that controls the drive device is informed that a defined angular position of the output shaft is present. This defined angular position is preferably the key withdrawal position of a locking cylinder when the drive device acts on a locking cylinder. The gear standstill during manual actuation is preferably achieved by self-locking the reduction gear. A further advantageous development provides that the engine is in the non-engine operated state is short-circuited via a resistor. This allows the driving torque to be adjusted from the turning handle to the output shaft. The short-circuit currents occurring in the motor due to eddy current excitation can be adjusted by measuring the resistance. The rotary handle for motorized rotation of the output shaft is preferably blocked by an electromagnetic blocking element. For this purpose, a lifting magnet is preferably used, the axially displaceable armature of which interacts with an external toothing of the rotary handle. If, for example, the motorized drive is desired, the motor is energized. At the same time, current is applied to the solenoid. The armature of the lifting magnet shifts from its retracted position into a feed position and engages with the head region of its armature in a tooth space in the external toothing, so that the rotatability of the rotary handle is blocked. Then the rotational movement of the motor axis causes a rotational movement of the output shaft. The rotary handle is preferably designed as a sleeve to accommodate the motor and the transmission. Gearbox and motor are preferably axially one behind the other. Two contact rings are attached to the outer wall of the sleeve, which can be picked up with grinders that are fixed to the fitting plate.

Ein rückwärtiges hohles Beschlagschild 1 bildet ein Gehäuse aus, welches einen Teil einer Drehhandhabe 8 aufnimmt und gegebenenfalls auch die in den Zeichnungen nicht dargestellte Steuerungselektronik für den Antriebsmotor bzw. den Hubmagneten 15. Das Beschlagschild 1 weist eine Öffnung 3 und eine Öffnung 20 auf. In die Öffnung 3 kann ein Türdrücker eingesteckt werden. In der Öffnung 20 lagert drehbar die hülsenartig ausgebildete Drehhandhabe 8.A rear hollow fitting plate 1 forms a housing which receives part of a rotary handle 8 and, if appropriate, also the control electronics for the drive motor or the lifting magnet 15, not shown in the drawings. The fitting plate 1 has an opening 3 and an opening 20. A door handle can be inserted into the opening 3. The sleeve-shaped rotary handle 8 is rotatably supported in the opening 20.

Die Rückseite des Gehäuses 1 wird von einer Platte 2 geschlossen, in welcher eine Öffnung vorgesehen ist, durch welche die Abtriebswelle 11 beschlagsrückseitig ausragt. Die Abtriebswelle 11 kann auf einen Schließzylinder wirken. Bevorzugt wirkt die Abtriebswelle 11 auf die eine Hälfte eines Gefahrenschließzylinders, welche Hälfte ohne die sonst übliche Stiftzuhaltung ausgebildet ist, sondern mit einer angepaßten Drehmitnahme für die Abtriebswelle 11.The rear of the housing 1 is closed by a plate 2, in which an opening is provided through which the output shaft 11 protrudes on the rear side of the fitting. The output shaft 11 can act on a locking cylinder. The output shaft 11 preferably acts on one half of a danger locking cylinder, which half is formed without the otherwise usual pin tumbler, but with an adapted rotary drive for the output shaft 11.

Auf der Abtriebswelle 11 sitzt drehfest im Bereich der Platte 2 eine Kontaktscheibe 12, welche sich zusammen mit der Antriebswelle 11 dreht. Die Kontaktscheibe 12 weist einen radial vorstehenden Nocken 13 auf, welcher mit einem Mikroschalter 14 zusammenwirkt. Der Mikroschalter 14 ist auf der Platte 2 befestigt. Wird der Mikroschalter 14, wie in Fig. 4 dargestellt, vom Nocken 13 beaufschlagt, so gibt der Mikroschalter 14 ein Signal an eine nicht dargestellte Steuerungselektronik ab.A contact disk 12, which rotates together with the drive shaft 11, sits on the output shaft 11 in a rotationally fixed manner in the area of the plate 2. The contact disk 12 has a radially projecting cam 13 which interacts with a microswitch 14. The microswitch 14 is fixed on the plate 2. If, as shown in FIG. 4, the microswitch 14 is acted upon by the cam 13, the microswitch 14 emits a signal to control electronics (not shown).

Die hülsenartig ausgebildete Drehhandhabe 8 durchgreift, wie oben beschrieben, die Öffnung 20 des Beschlagschildes und weist auf der Beschlagschildrückseite einen durchmesservergrößerten Abschnitt auf. Dieser durchmesservergrößerte Abschnitt weist im Bereich der Beschlagschildrückseite eine Verzahnung 17 auf. Mit dieser Umfangsverzahnung wirkt ein Sperranker 16 eines Hubmagneten 15 zusammen. Ist der Hubmagnet 15 nicht strombeaufschlagt, so ist der Sperranker 16 in seiner in Fig. 2 dargestellten zurückgezogenen Stellung. Wird der Hubmagnet 15 strombeaufschlagt, so wird der Sperranker 16 axial vorgefahren und greift, wie in Fig. 3 gestrichelt dargestellt, in eine Zahnöffnung der Verzahnung 17 ein, so daß die Drehhandhabe 8 drehgesperrt ist.The sleeve-like rotary handle 8, as described above, passes through the opening 20 of the fitting plate and has a section with an enlarged diameter on the rear side of the fitting plate. This enlarged section has a toothing 17 in the area of the rear of the fitting plate. A locking armature 16 of a lifting magnet 15 interacts with this circumferential toothing. If the solenoid 15 is not energized, the locking armature 16 is in its retracted position shown in FIG. 2. If the lifting magnet 15 is energized, the locking armature 16 is advanced axially and, as shown in broken lines in FIG. 3, engages in a tooth opening of the toothing 17, so that the rotary handle 8 is locked against rotation.

Der durchmesservergrößerte Abschnitt der Drehhandhabe 8 weist im Hohlraum des Beschlagschildes 1 ferner einen Schleifkontakt auf, welcher aus zwei nebeneinanderliegenden Kontaktringen 9 und zwei diese Kontaktringe 9 abgreifende Schleifkontakte 10 besteht. Die Schleifkontakte 10 sind am Beschlagschild 1 befestigt. Die Kontaktringe 9 sind elektrisch leitend mit der Motorwicklung verbunden.The diameter-enlarged section of the rotary handle 8 also has a sliding contact in the cavity of the fitting plate 1, which consists of two adjacent contact rings 9 and two sliding contacts 10 which grip these contact rings 9. The sliding contacts 10 are attached to the fitting plate 1. The contact rings 9 are electrically conductively connected to the motor winding.

In der zentralen Höhlung der Betätigungshandhabe 8 liegen axial hintereinandergeordnet ein Elektromotor 5 und ein Untersetzungsgetriebe 6, welche zusammen den Getriebemotor 4 ausbilden. Koaxial zur Drehhandhabe 8 ragt aus dem Getriebe 6 die Getriebeabtriebswelle heraus; die Getriebeabtriebswelle bildet die Abtriebswelle 11 der Vorrichtung aus. Die Hülse ist stirnseitig mit einer Abdeckung 19 versehen.An electric motor 5 and a reduction gear 6, which together form the gear motor 4, lie axially one behind the other in the central cavity of the actuation handle 8. The transmission output shaft protrudes coaxially to the rotary handle 8 from the transmission 6; the transmission output shaft forms the output shaft 11 of the device. The sleeve is provided on the end face with a cover 19.

Die Schleifkontakte 10 sind ebenso wie die nicht dargestellten Anschlüsse des Hubmagnetes und die Kontakte des Mikroschalters 14 mit einer nicht dargestellten Steuerungselektronik verbunden, welche bevorzugt in der Höhlung des Beschlagschildes 1 angeordnet ist. Ebenfalls mit der Steuerelektronik verbunden ist ein nicht dargestellter Schalter, welcher der Steuerelektronik den Schließzustand der Tür vermittelt. Dieser Schalter ist bevorzugt im Falzbereich der Tür ausgebildet und wirkt mit der Zarge oder dem Rahmen zusammen.The sliding contacts 10 are just like the connections of the solenoid and the contacts, not shown of the microswitch 14 is connected to control electronics, not shown, which is preferably arranged in the cavity of the fitting plate 1. Also connected to the control electronics is a switch, not shown, which conveys the closed state of the door to the control electronics. This switch is preferably formed in the rebate area of the door and interacts with the frame or the frame.

Wird eine mit einem derartigen Motorbeschlag ausgebildete Tür geschlossen, so erhält die Steuerungselektronik von dem nicht dargestellten Schalter ein Signal, daß die Tür geschlossen ist. Sodann erfolgt eine Strombeaufschlagung des Elektromotors 5 und des Hubmagneten 15 durch die Steuerungselektronik. Die Auswärtsverlagerung des Ankers 16 führt zu einer Drehsperrung der Drehhandhabe 8. Die Beaufschlagung des Motors mit elektrischem Strom führt zu einer Drehbewegung der Abtriebswelle 11 und damit zu einer Schließbetätigung des Schließzylinders und des Schlosses. Die Drehbewegung erfolgt entweder so lange, bis über den Schalter 14 und den Nocken 3 zwei Vorschlußumdrehungen gezählt werden oder der Getriebemotor 4 bei vollständig ausgeschlossenem Riegel blockiert. Die dann erfolgende hohe Stromentnahme signalisiert der Steuerungselektronik, daß eine Endstellung erzielt ist. Sodann erfolgt eine Rückdrehung des Getriebemotors 4, bis der Nocken 13 den Schalter 14 beaufschlagt hat. In dieser Stellung ist der Schließzylinder in seiner Schlüsselabzugsstellung.If a door designed with such a motor fitting is closed, the control electronics receive a signal from the switch (not shown) that the door is closed. Then a current is applied to the electric motor 5 and the lifting magnet 15 by the control electronics. The outward displacement of the armature 16 leads to the rotary handle 8 being locked against rotation. The application of electric current to the motor leads to a rotary movement of the output shaft 11 and thus to a locking actuation of the locking cylinder and the lock. The rotary movement either takes place until two preliminary turns are counted via the switch 14 and the cam 3, or the geared motor 4 blocks when the bolt is completely excluded. The high current drain then signals the control electronics that an end position has been reached. The geared motor 4 is then turned back until the cam 13 has acted on the switch 14. In this position, the lock cylinder is in its key withdrawal position.

Soll das Schloß geöffnet werden, so kann dies durch Betätigung der Drehhandhabe 8 erfolgen. Die Selbsthemmung des Getriebes 6 bewirkt eine Drehmitnahme der Antriebswelle 11, wenn die Drehhandhabe 8 gedreht wird. Die Drehhandhabe 8 kann sowohl in Öffnungsstellung, als auch in geschlossener Stellung des Schlosses gedreht werden. Es ist auch eine Wechselbetätigung vorgesehen. Es wird als vorteilhaft angesehen, daß die Verbindung zwischen der Abtriebswelle 11 und der Drehhandhabe 8 drehmomentgekoppelt ist, also nicht völlig starr ist. Hierdurch ist das maximal auf den Schließzylinder ausübbare Drehmoment begrenzt. Durch die Einstellung eines Kurzschlußwiderstandes in die Zuleitung zum Elektromotor kann dieses Übertragungsdrehmoment eingestellt werden.If the lock is to be opened, this can be done by actuating the rotary handle 8. The self-locking of the gear 6 causes the drive shaft 11 to be rotated when the turning handle 8 is rotated. The rotary handle 8 can be in the open position, as well as in the closed position of the lock. A changeover operation is also provided. It is considered advantageous that the connection between the output shaft 11 and the turning handle 8 is torque-coupled, that is, it is not completely rigid. This limits the maximum torque that can be exerted on the locking cylinder. By setting a short-circuit resistance in the supply line to the electric motor, this transmission torque can be set.

Soll das Schloß elektrisch geöffnet werden, so erfolgt ebenfalls eine Betätigung des Hubmagneten 15. Damit einhergehend wird die manuelle Drehbarkeit der Handhabe 8 blockiert. Eine Drehung der Motorwelle 5 wird sodann über das Untersetzungsgetriebe 6 auf die Abtriebswelle 11 übertragen. Der Motor 5 wird so lange betätigt, bis er in eine Anschlagstellung läuft. Dies entspricht dann einer Wechselbetätigung des Schlosses. In dieser Stellung verharrt die Vorrichtung eine voreinstellbare Zeit, um dann anschließend wieder zurückzudrehen, bis die Schlüsselabzugsstellung erreicht ist.If the lock is to be opened electrically, the lifting magnet 15 is also actuated. In addition, the manual rotation of the handle 8 is blocked. Rotation of the motor shaft 5 is then transmitted to the output shaft 11 via the reduction gear 6. The motor 5 is operated until it runs into a stop position. This then corresponds to changing the lock. The device remains in this position for a presettable time, in order then to turn it back again until the key withdrawal position is reached.

Die besonderen Vorteile der Erfindung werden darin gesehen, daß ein festsitzender Getriebemotor im Knauf sitzt, wobei die Stromzufuhr über Schleifkontakte erfolgt. Bei Handbetrieb, d. h. bei Betätigung des Knaufes (Drehhandhabe) oder durch Schlüssel tritt nur die Lagerreibung auf. Getriebe und Motor werden nicht mitgedreht. Es können kleine, handelsübliche Getriebemotoren verwendet werden. Es ist eine sehr geringe Baugröße möglich. Das Getriebe hat bevorzugt eine Selbsthemmung von 0,6 Newtonmeter. Bei Überschreitung dieses Drehmomentes fängt der Motor an, sich zu drehen. Wird der Motor mitgedreht, so erfolgt dort eine Induktion. Ist der Motor mit einem Kurzschlußwiderstand versehen, so wird der Motor als Wirbelstrombremse. Über die Größe des Widerstandes kann die Bremswirkung eingestellt werden. Es wird ferner als bevorzugt angesehen, daß keine Wellen ge- und entkuppelt werden müssen, wenn von der manuellen Betätigung in die motorische Betätigung gewechselt werden soll. Bei Knaufbetätigung ist ein direkter 1:1-Betrieb gewährleistet.The particular advantages of the invention are seen in the fact that a stuck gear motor is seated in the knob, the current being supplied via sliding contacts. In manual operation, ie when the knob is operated (turning handle) or with a key, only the bearing friction occurs. The gearbox and motor are not turned. Small, commercially available geared motors can be used. A very small size is possible. The gearbox preferably has a self-locking of 0.6 Newton meters. If this torque is exceeded, the motor starts to turn. If the motor is also rotated, there is one Induction. If the motor is provided with a short-circuit resistor, the motor is used as an eddy current brake. The braking effect can be adjusted via the size of the resistance. It is also considered preferable that no shafts need to be coupled and uncoupled when changing from manual to motorized actuation. Direct 1: 1 operation is guaranteed when the knob is operated.
