Die Erfindung betrifft eine Antriebsvorrichtung gemäß
Gattungsbegriff des Anspruches 1.The invention relates to a drive device according to
Generic term of
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 the German Patent 36 06 531 shown. At the back of a hardware label a rotatable output shaft protrudes into the Core area of a locking cylinder. The output shaft continues to the front of the fitting and is there rotatably connected with a turning handle. The Fitting label shows an electrically operated motor on which has a reduction gear and a Belt drive acts on the output shaft.
Der Erfindung liegt die Aufgabe zugrunde, einen derartigen Motorbeschlag handhabungstechnisch zu verbessern und fertigungstechnisch zu vereinfachen.The invention has for its object such Improve engine fitting handling and to simplify manufacturing technology.
Gelöst wird die Aufgabe in der in den Ansprüchen angegebenen Erfindung.The problem is solved in the manner specified in the claims Invention.
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.According to the embodiment of the invention is a given easy to manufacture device.

With the for closing actuation Technically, the transmission has the usual torques a rigid transmission link. The device has the Effect as if the output shaft essentially would be rigidly connected to the turning handle if the Engine is not driven. In this first, manual Operating mode can be that exerted on the turning handle Rotational movement directly on the output shaft and thus transferred to the lock or the lock cylinder become. If the drive device in its second mode are used, so the rotatability the turning handle is blocked. An electric one Activation of the motor leads to its rotation.

This is an extremely low-friction manual operation given. A further education the invention provides that the output shaft a Contact disc carries which rotatably with the shaft connected is. The contact disc works with you Position switch or a position detector together. The contact disk preferably has a cam, which interacts with a microswitch. Becomes the microswitch is acted upon by the cam, so an electronic control of the drive device Control teaches that a defined angular position the output shaft is present.

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
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 back of the
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. On the
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 passes through,
as described above, the
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 enlarged-diameter section of the turning handle 8
also has one in the cavity of the
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.In the central cavity of the operating handle 8

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
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.Will be trained with such a motor fitting
The door is closed, so the control electronics receive
from the switch, not shown, a signal that
the door is closed. Then a current is applied
of the
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
The turning handle 8 is actuated. The self-locking
of the
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, this is done

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 therein seen that a stuck gear motor in the knob sits, with the power supply via sliding contacts. In manual mode, i.e. H. when operating the knob (Turning handle) or only the key occurs Bearing friction on. Transmission and engine are not turned. It can be small, commercially available geared motors be used. It is a very minor one Size possible. The transmission preferably has one Self-locking of 0.6 Newton meters. If exceeded of this torque the motor starts to turn. If the motor is also rotated, there is one Induction. Is the motor with a short circuit resistor provided, the motor is used as an eddy current brake. The braking effect can be determined by the size of the resistance can be set. It is also preferred viewed that no shafts are coupled and uncoupled need when moving from manual to motor Actuation should be changed. With knob operation direct 1: 1 operation is guaranteed.
