Abstract

The electronic control with at least one accumulator and at least one micro-processor releases sensor signals via a cog wheel on a driven shaft which is connected by connecting rods and operating arm to the revolving door. Between the driven shaft and the connecting rods or operating arm is a gear changing its transmission ratio by means of the swing angle of the revolving door. The gear has two inter-engaging cog wheels (8,13) each formed by a circular gear rim and mounted eccentrically in relation to their center points (16,17). The first cog wheel operates in conjunction with a driven shaft, and the second cog wheel operates coaxially in relation to its rotary point (18) with the driven cog wheel. The rotary axis of the driven shaft runs through the rotary point (15) of the first cog wheel.

Description

Die Erfindung betrifft einen Drehtürantrieb gemäß der in den Oberbegriffen der Patentansprüche 1 und 2 angegebenen Art.The invention relates to a swing door drive according to the in the preambles of claims 1 and 2 specified Art.

Aus der DE 41 24 282 C2 ist ein gattungsgemäßer Drehtürantrieb bekannt, bei dem das automatische Öffnen der angeschlossenen Tür über den Drehtürantrieb in elektromechanischer Weise erfolgt. Der Schließvorgang wird mit Unterstützung des Motorantriebes über eine eingebaute Schließfeder, die sich z.B. in einem handelsüblichen Türschließer befindet, bewerkstelligt. Dabei wird der Motorantrieb mit einem reduzierten Antriebsmoment beaufschlagt, wobei der Motor nur die Verluste des Getriebes ausgleicht. Ein dauerndes Schalten der Kupplung wird durch diese Art der Steuerung vermieden, welches gleichzeitig einen geringen Verschleiß bedeutet, denn es braucht beim Reversiervorgang der Drehtür nicht extra wieder die Kupplung eingekuppelt werden. Dieser Drehtürantrieb ist mit einem sogenannten Scherengestänge ausgestattet.From DE 41 24 282 C2 a generic swing door drive is known in which the automatic opening of the connected door via the swing door drive is carried out in an electromechanical manner. The closing process is built in with the support of the motor drive Closing spring, e.g. in a standard door closer, accomplished. The motor drive is reduced Drive torque applied, the motor only the losses of the transmission compensates. A permanent switching of the clutch is due to this Type of control avoided, which at the same time low wear means because it takes the revolving door to reverse the clutch cannot be engaged again. This swing door drive is equipped with a so-called scissor linkage.

Ein solcher Antrieb kann auf dem Türrahmen oder der Tür montiert werden. Neben der vorbeschriebenen Anordnung eines Scherengestänges kann auch ein Parallelgestänge und eine sogenannte Gleitschiene in Verbindung mit einem geraden Betätigungsarm verwendet werden. Während die Schließmomente für Scheren- und Parallelgestänge den genormten Vorgaben genügen, zeigen sich für den Schließvorgang bei Verwendung einer Gleitschiene in der Regel sehr niedrige Schließmomente.Such a drive can be mounted on the door frame or the door. In addition to the arrangement of a scissor linkage described above can also be a parallel linkage and a so-called slide rail in Connection with a straight actuating arm can be used. While the closing torques for scissors and parallel rods are the standardized ones Specifications are sufficient for the closing process when in use a slide rail usually very low closing torques.

Eine Vorrichtung zum Öffnen und Schließen von Türen zeigt die DE 37 30 114 A1, die aus zwei Montageteilen besteht. Das eine Teil wird am Türblatt und das andere Teil der Vorrichtung wird rahmenseitig befestigt, wobei beide Montageteile untereinander durch einen Kraftübertragungsmechanismus miteinander verbunden sind. Gleichzeitig ist ein Umkehrmechanismus mit einer Rastkupplung vorhanden, die gleichzeitig die zu übertragenden Kräfte begrenzt. Hierzu können auch bewährte handelsübliche Türschließer verwendet werden. Das Abtriebsrad der Vorrichtung, welches einerseits mit dem Kraftübertragungsmechanismus verbunden ist, weist ein Ritzel auf, welches mit einer Zahnstange in Wirkverbindung steht.DE 37 30 shows a device for opening and closing doors 114 A1, which consists of two assembly parts. One part is on the door leaf and the other part of the device is attached to the frame, whereby both assembly parts with each other through a power transmission mechanism are interconnected. At the same time is a reversal mechanism with a snap-in coupling available, which at the same time transmitting forces limited. Proven commercially available can also be used for this Door closers can be used. The output gear of the device, which on the one hand is connected to the power transmission mechanism is, has a pinion, which is operatively connected to a rack stands.

Ein ähnlich arbeitender Drehtürantrieb wird in der WO 89/11578 beschrieben, wobei hier ebenfalls für den Öffnungsvorgang eine Vorrichtung vorhanden ist und der Schließvorgang wie bei der DE 41 24 282 C2 durch die Kraft des Türschließers bewerkstelligt wird.A similarly operating swing door drive is described in WO 89/11578, here also a device for the opening process is present and the closing process as in DE 41 24 282 C2 the power of the door closer is achieved.

Ähnliche Drehtürantriebe werden in der US 1,684,704 sowie 2,256,613 wiedergegeben. Auch hier sind Antriebe in Verbindung mit Türschließern wiedergegeben, wobei jedoch der Türschließer als separates Bauteil auf dem Flügel montiert ist und der Drehflügelantrieb oberhalb des Türflügels sich befindet. Die Verbindung zwischen Drehtürantrieb und Türschließer wird durch ein Scherengestänge bewerkstelligt. Die US 4,333,270 offenbart einen Drehtürantrieb, der elektromechanisch arbeitet. Dabei wirkt ein Antriebsrad mit einer Zahnstange derart zusammen, daß eine Feder für die Schließung der Tür beim Öffnungsvorgang gespannt wird.Similar swing door drives are in US 1,684,704 and 2,256,613 reproduced. Here, too, drives are connected to door closers reproduced, but with the door closer as a separate component the wing is mounted and the swing door drive above the door wing located. The connection between the swing door drive and the door closer is accomplished by a pair of scissors. US 4,333,270 discloses a swing door operator that works electromechanically. It works Drive wheel together with a rack so that a spring for the closing of the door is stretched during the opening process.

Einen elektromechanischen Drehtürantrieb, der einen Gleichstrommotor in Verbindung mit einem Planetengetriebe zum Antrieb verwendet offenbart die DE 32 02 930 A1. Zwischen der Abtriebswelle und der angeschlossenen Tür ist ein Kniehebelgestänge vorhanden. Dieser Drehtürantrieb wird sowohl für den Öffnungs- als auch für den Schließvorgang der angeschlossenen Tür verwendet.An electromechanical swing door drive that uses a DC motor disclosed in connection with a planetary gear used for driving DE 32 02 930 A1. Between the output shaft and the connected one There is a toggle linkage in the door. This swing door drive is used for both the opening and the closing process connected door used.

Ein elektrohydraulischer Drehtürantrieb mit der Typenbezeichnung ED 200 wird in dem Firmenprospekt der DORMA GmbH + Co. KG als ein kompakter Antrieb, der die Tür gegen eine Feder öffnet und mechanisch durch die Rückstellkräfte der Feder wieder in seine Schließlage geht, wiedergegeben. Dabei kann der Antrieb auf dem Türrahmen oder auf der Tür montiert werden. Dabei wird durch einen Elektromotor eine Pumpe angetrieben, die ein entsprechendes Ölvolumen in einen Hydraulikzylinder pumpt, der sich wiederum gegen eine Feder ausdehnt. Dabei ist der Kolben des Hydraulikzylinders mit einer Zahnung versehen, die ein Ritzel antreibt, an das der Hebelmechanismus zur Betätigung der Tür angebracht ist. Um die angeschlossene Tür nun wieder in ihre Schließlage zu bringen, werden entsprechende Ventile geöffnet und das Ölvolumen kann in den Tank der Antriebseinheit wieder zurückfließen. Die Feder schiebt dabei den Kolben zurück und schließt durch seine Bewegung, die auf das Ritzel übertragen wird, die Tür.An electrohydraulic swing door drive with the type designation ED 200 appears as one in the company brochure of DORMA GmbH + Co. KG compact drive that opens the door against a spring and mechanical returns to its closed position due to the restoring forces of the spring, reproduced. The drive can be on the door frame or on the Door can be mounted. Here, an electric motor turns a pump driven, the corresponding oil volume in a hydraulic cylinder pumps, which in turn expands against a spring. Here is the Piston of the hydraulic cylinder is provided with a toothing, which is a pinion drives to which the lever mechanism for actuating the door is attached is. Around the connected door now again in its closed position appropriate valves are opened and the oil volume can flow back into the drive unit tank. The spring pushes while doing so the piston closes and closes by its movement, which on the Pinion is transmitted to the door.

Die Aufgabe der Erfindung ist es deshalb, einen Drehtürantrieb gemäß dem Stand der Technik derart weiterzubilden, daß unter Verwendung der genannten Nachteile eine einfache Konstruktion sowie eine problemlose Anpassung an gewünschte Drehmomentverläufe über den Öffnungswinkel ermöglicht werden.The object of the invention is therefore according to a swing door drive the state of the art in such a way that using the mentioned disadvantages a simple construction and a problem-free Adaptation to the desired torque curves via the opening angle be made possible.

Diese Aufgabe wird durch die kennzeichnenden Merkmale der Ansprüche 1 und 2 in Verbindung mit ihren Oberbegriffsmerkmalen gelöst. Weitere vorteilhafte Ausgestaltungsformen der Erfindung bilden die Merkmale der Unteransprüche.This object is achieved through the characterizing features of the claims 1 and 2 solved in connection with their generic features. Further advantageous embodiments of the invention form the features of Subclaims.

Der Erfindung liegt die Erkenntnis zugrunde, daß der sich über den Öffnungswinkel einer Tür (Drehflügel) ändernde Kraftverlauf/Drehmomentenverlauf sowohl beim Öffnen als auch beim Schließen über ein Getriebe in Form einer Vorrichtung mit einem sich über den Öffnungswinkel ändernden Übersetzungsverhältnis beeinflußt werden kann, das sich durch exentrisch angeordnete und einen kreisförmigen Zahnkranz aufweisende Zahnräder ergibt, die sich einfach herstellen lassen.The invention is based on the finding that the opening angle of a door (rotating leaf) changing force curve / torque curve both when opening and when closing via a gear in Form of a device with a changing over the opening angle Gear ratio can be influenced by eccentrically arranged and having a circular ring gear Gears result that are easy to manufacture.

Nach der Erfindung weist daher das sich über den Öffnungswinkel (Drehwinkel) der Tür in seinem Übersetzungsverhältnis ändernden Getriebe ein erstes und ein zweites miteinander kämmendes, jeweils durch einen kreisförmigen Zahnkranz gebildetes Zahnrad auf, die unter Beibehaltung ihres Achsabstandes exzentrisch zu ihren Mittelpunkten gelagert sind und denen das erste Zahnrad mit einer Abtriebswelle und das zweite Zahnrad mit einem Zahnrad der Antriebsvorrichtung verbunden ist, wobei die Drehachse der Abtriebswelle durch den Drehpunkt des ersten Zahnrades verläuft, dies alles in derartiger Anordnung, daß die sich jeweils durch den Mittelpunkt eines Zahnrades und dem neuen Drehpunkt ergebende Exzentrizität der Zahnräder punktsymmetrisch zu deren Wälzpunkt liegt. According to the invention, this therefore shows the opening angle (Angle of rotation) of the door in its gear ratio changing gear a first and a second meshing, each by a circular gear ring formed gear, while maintaining their center distance eccentrically to their centers and the first gear with an output shaft and the second Gear is connected to a gear of the drive device, wherein the axis of rotation of the output shaft through the pivot point of the first gear runs, all in such an arrangement that each through the center of a gear and the new pivot point Eccentricity of the gears point symmetrical to their pitch point lies.

Auf einfache Weise können nunmehr die Drehmomentenverläufe durch Wahl der Exzentrizität, der Wälzkreisdurchmesser und des sich daraus ergebenden Abstandes der Drehachsen der beiden Zahnräder festgelegt und ohne weiteres bestimmt werden. Hierdurch ergeben sich vielfältige Übersetzungsverhältnisse und somit Anpassungsmöglichkeiten an gewünschte Drehmomentencharakteristika über den Öffnungswinkel, ohne das Sonderanfertigungen von Zahnkurvenscheiben notwendig sind. Vielmehr können im Handel erhältliche Zahnräder verwendet werden, wodurch die Fertigungskosten erheblich gesenkt werden. Zudem können die Zahnräder insbesondere eine Normalverzahnung aufweisen.The torque curves can now be carried out in a simple manner Choice of the eccentricity, the pitch circle diameter and the resulting resulting distance of the axes of rotation of the two gears set and can be easily determined. This results in many Gear ratios and thus adjustment options to the desired Torque characteristics over the opening angle, without that custom-made toothed cams are necessary. Much more commercially available gears can be used, whereby manufacturing costs are significantly reduced. In addition, the Gears in particular have a normal toothing.

Die Größe der Exzentrizität wird durch das Verhältnis vom Betrag derselben zum Grundkreisdurchmesser beschrieben. Insbesondere sollte dieses Verhältnis einen Wert von 0,137 für Verzahnungen nach DIN 867 nicht überschreiten. Das Übertragungsverhalten des Getriebes wird jedoch bei einer Überschreizung dieses Verhältnisses deutlich verschlechtert, da die Profilüberdeckung unter 1 sinken kann.The size of the eccentricity is determined by the ratio of its amount described for the base circle diameter. In particular, this should Ratio a value of 0.137 for gears according to DIN 867 do not exceed. The transmission behavior of the gearbox, however if this ratio is overestimated, it deteriorates significantly, because the profile coverage can drop below 1.

Gemäß einer Ausführungsform der Erfindung ist der Drehtürantrieb als Obenantrieb mit einem zwischen einem Anlenkpunkt des drehbeweglichen Drehflügels der zugeordneten Tür und einem weiteren Anlenkpunkt außerhalb des Drehflügels über den Drehbereich sich ändernden wirksamen Hebelarm ausgebildet, der an die Abtriebswelle angreift.According to one embodiment of the invention, the swing door drive is as Top drive with one between a pivot point of the rotatable Swivel wing of the assigned door and a further articulation point effective outside of the rotating wing over the rotating range changing Lever arm designed to engage the output shaft.

Vorzugsweise wird der wirksame Hebelarm durch ein Gleitschienengestänge und ein Kniehebelgestänge gebildet.The effective lever arm is preferably by means of a slide rail linkage and formed a toggle linkage.

The two gears of the device of Figure 1 with respect to the position of the center of rotation and.

Das in der Figur 1 ausschnittsweise wiedergegebene Getriebe der Vorrichtung 2 ist mit einem Zahnrad 1, welches sich auf einer nicht dargestellten Welle des Drehflügelantriebes befindet angeschlossen. Mit diesem Zahnrad 1 steht in Wirkverbindung ein weiteres Zahnrad 4, wobei die Drehachse 3 des Zahnrades 4 und die Drehachse eines Zahnrades 13 identisch sind.The transmission of the device shown in detail in FIG. 1 2 is with a gear 1, which is on a not shown The rotary vane drive shaft is connected. With this Gear 1 is operatively connected to another gear 4, the Axis of rotation 3 of gear 4 and the axis of rotation of a gear 13 are identical.

Das Zahnrad 13 kämmt mit einem weiteren Zahnrad 8, das mit einer aus der Vorrichtung austretenden Abtriebswelle 6 verbunden ist. Die Abtriebswelle 6 ist koaxial zu einer Drehachse 7 des Zahnrades 8 angeordnet.The gear 13 meshes with another gear 8, the one with the output shaft 6 emerging from the device is connected. The output shaft 6 is arranged coaxially with an axis of rotation 7 of the gear wheel 8.

Die beiden Zahnräder 13 und 8 sind mit einer Normalverzahnung versehen und im Hinblick auf ihre Mittelachse 12 bzw. 9 um einen vorbestimmten Betrag a exzentrisch drehbar gelagert. Die Drehachse 3 des Zahnrades 13 ist somit von ihrer Mittelachse 12 und die Drehachse des Zahnrades 8 von ihrer Mittelachse 9 jeweils um den Betrag a beabstandet.The two gears 13 and 8 are provided with normal toothing and with respect to their central axis 12 or 9 by a predetermined Amount a rotatably mounted eccentrically. The axis of rotation 3 of the gear 13 is thus from its central axis 12 and the axis of rotation of the gear 8 spaced from their central axis 9 by the amount a.

An die Abtriebswelle kann in bekannter Weise ein Kniehebel oder ein Gleitschienengestänge angreifen. Der Drehtürantrieb kann aber auch als Unterbodenantrieb ausgebildet sein, wobei die Abtriebswelle 6 dann mit einem hier nicht dargestellten Lager eines Drehflügels zusammenwirkt.A toggle lever or a can be connected to the output shaft in a known manner Attack the slide rail linkage. The swing door drive can also be used as Underbody drive can be formed, the output shaft 6 then with interacts a bearing of a rotary wing, not shown here.

In Figur 2 sind die miteinander kämmenden Zahnräder 13 und 8 im Zusammenhang mit einem xy Koordinatensystem dargestellt, wobei die X-Achse die beiden durch die Drehachsen 3 und 7 gebildeten Drehpunkte 18 und 15 miteinander verbindet. Die durch die Mittelachsen 12 und 9 gebildeten Mittelpunkte 17 und 16 weisen jeweils zu dem zugeordneten Drehpunkt 18 bzw. 15 den die Exzentrizität bestimmenden Abstand auf. Die Mittelpunkte 17 und 16 beziehen sich auf einem kreisförmigen Zahnkranz des jeweiligen Zahnrades 13 bzw. 8 mit kreisförmigen Fußkreis, Kopfkreis, Wälzkreis und ähnlichem. In Figure 2, the meshing gears 13 and 8 are related represented with an xy coordinate system, with the X axis the two pivot points formed by the axes of rotation 3 and 7 18 and 15 connects together. The through the central axes 12 and 9 Center points 17 and 16 formed each point to the assigned one Pivot point 18 or 15 the distance determining the eccentricity. The center points 17 and 16 relate to a circular ring gear of the respective gear 13 or 8 with a circular base circle, Tip circle, pitch circle and the like.

Wie die Figur 2 deutlich macht, ist die durch den Mittelpunkt 17 und den Drehpunkt 18 bzw. durch den Mittelpunkt 16 und den Drehpunkt 15 gebildete Exzentrizität a punktsymmetrisch zu einem Wälzpunkt 11, der beiden miteinander kämmenden Zahnräder 13 und 8, in dem sich die beiden Wälzkreise 10 und 19 der Zahnräder 13 und 8 berühren.As FIG. 2 makes clear, this is due to the center 17 and the Pivot point 18 or formed by the center point 16 and the pivot point 15 Eccentricity a point symmetrical to a pitch point 11, the two intermeshing gears 13 and 8, in which the two Touch pitch circles 10 and 19 of gears 13 and 8.

Die Zahnräder 13 und 8 weisen eine einander entsprechende Bauform auf. Hierdurch wird es ermöglicht, daß mit Drehen der Zahnräder 13 und 8 sich der Abstand vom Drehpunkt 18 zum Wälzpunkt 11 zunehmend in dem Maße vergrößert bzw. verkleinert, wie der Abstand des Drehpunktes 15 zum Wälzpunkt 11 sich verkleinert bzw. sich vergrößert. Der Abstand der Drehpunkte 18 und 15 der beiden Zahnräder 13 und 8 zueinander bleibt hierbei während des Drehens der Zahnräder 13 und 8 jedoch konstant.The gears 13 and 8 have a corresponding design on. This enables the gears 13 and 8 to rotate the distance from the pivot point 18 to the pitch point 11 increasingly increases in the size increased or decreased as the distance of the fulcrum 15 to the pitch point 11 decreases or increases. The distance the fulcrums 18 and 15 of the two gears 13 and 8 to each other remains constant during the rotation of the gears 13 and 8.

Hierdurch wird auf einfache Art ein sich Ändern des Übersetzungsverhältnisses beim Drehen der Zahnräder 13 und 8 und somit der Abtriebswelle 6 erreicht. Über den Öffnungswinkel eines Drehflügels kann dadurch Einfluß auf den sich beispielsweise durch ein Gleitschienengestänge ändernden wirksamen Hebelarm und somit auf den über den Öffnungswinkel sich ändernden Kraft- und Drehmomentenverlauf genommen werden. Je nach Exzentrizität und Wälzkreisdurchmesser kann das Übersetzungsverhältnis auf einfache Art und Weise an vorbestimmte Drehmomentenverlaufscharakteristika angepaßt werden. This is a simple way to change the gear ratio when turning the gears 13 and 8 and thus the output shaft 6 reached. As a result, the opening angle of a rotary sash can Influence on, for example, a slide rail linkage changing effective lever arm and thus on the opening angle changing force and torque curve taken become. Depending on the eccentricity and pitch circle diameter, the gear ratio can in a simple manner to predetermined torque curve characteristics be adjusted.
