Abstract

The invention relates to a door actuator with a motor-gear unit and a spring (7) acting as an energy storage device. To produce a door actuator, wherein two variants are formed for sliding or shear rails by substituting an individual component, the pretensioning of the spring (7) can be actively varied by the motor-gear unit, thus producing the desired closure torque profile.

Description

Titel: Türantrieb mit während der Türbewegung veränderbarer FedervorspannungTitle: Door operator with spring preload that can be changed during door movement
Beschreibungdescription
Die Erfindung betrifft einen Türantrieb, mit einer Motor-Getriebe-Einheit und einer als Energiespeicher wirkenden Feder.The invention relates to a door drive with a motor-gear unit and a spring acting as an energy store.
Bei einem Drehflügeltürantrieb gibt es für die Übertragung der Antriebs- leistung des Türantriebes auf das Türblatt grundsätzlich zwei Möglichkeiten: Scherengestänge und Gleitschiene bzw. abgeleitete Anordnungen mit vergleichbaren Wirkprinzipien. Je nach Montagesituation empfiehlt sich die Verwendung des einen oder des anderen Übertragungsmechanismus. Die für die normgerechte Selbstschließung erforderlichen Momentenver- laufe an der Tür bedingen jedoch für jeden Übertragungsmechanismus unterschiedliche, über den Türöffnungswinkel veränderliche Achsmo- mentenverläufe, so dass je nach Übertragungsmechanismus auch unterschiedliche Motor-Getriebe-Einheiten eingesetzt werden müssen. Dies erfordert jedoch einen hohen Aufwand an Bauteilen und führt zu einer großen Variantenbildung.With a swing door operator, there are basically two options for transferring the drive power of the door operator to the door leaf: scissor linkage and slide rail or derived arrangements with comparable operating principles. Depending on the installation situation, the use of one or the other transmission mechanism is recommended. However, the torque profiles on the door required for the self-closing in accordance with the standards require different axis torque profiles for each transmission mechanism that can be changed via the door opening angle, so that different motor-gearbox units must be used depending on the transmission mechanism. However, this requires a lot of components and leads to a large number of variants.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Türantrieb zu schaffen, bei dem durch den Austausch eines einzigen Bauteils zwei Varianten für Scherengestänge bzw. Gleitschienengestänge gebildet werden. Damit wird eine maximale Anzahl von Gleichteilen erreicht.It is therefore an object of the present invention to provide a door drive in which two variants for scissor linkage or slide rail linkage are formed by replacing a single component. A maximum number of identical parts is thus achieved.
Die Lösung dieser Aufgabe erfolgt durch einen Türantrieb, mit einer Motor- Getriebe-Einheit und einer als Energiespeicher wirkenden Feder, dadurch, dass die Vorspannung der Feder von der Motor-Getriebe-Einheit aktiv veränderbar ist. Infolge dieser Ausgestaltung kann ein und derselbe Türantrieb für beide Arten von Übertragungsmechanismen eingesetzt werden. Je nach gewähltem Übertragungsmechanismus braucht lediglich die Vorspannung der Feder entsprechend angepasst zu werden.This problem is solved by a door drive, with a motor-gear unit and a spring acting as an energy store, in that the preload of the spring can be actively changed by the motor-gear unit. As a result of this configuration, one and the same door drive can be used for both types of transmission mechanisms. Depending on the transmission mechanism selected, only the spring preload needs to be adjusted accordingly.
Die Unteransprüche beinhalten vorteilhafte Weiterbildungen der Erfindung.The subclaims contain advantageous developments of the invention.
Nach einer vorteilhaften Weiterbildung stützt sich die Feder gegen ein Widerlager ab und die Änderung der Vorspannung der Feder erfolgt durch eine Lageveränderung des Widerlagers.According to an advantageous development, the spring is supported against an abutment and the bias of the spring is changed by changing the position of the abutment.
Vorteilhafterweise weist die Motor-Getriebe-Einheit mindestens ein Zahnrad auf, das mit einer Zahnstange kämmt.The motor-transmission unit advantageously has at least one gear that meshes with a toothed rack.
Das Zahnrad besteht nach einer bevorzugten Ausführungsform aus zwei parallelen Zahnscheiben und einer dazwischen angeordneten Nabe.According to a preferred embodiment, the toothed wheel consists of two parallel toothed disks and a hub arranged between them.
Die Nabe weist vorteilhafterweise eine im Radius veränderliche Kontur auf.The hub advantageously has a contour that is variable in radius.
Die Zahnstange weist nach einer vorteilhaften Ausgestaltung einen in ihrer Längsrichtung verlaufenden Schlitz auf.According to an advantageous embodiment, the rack has a slot running in its longitudinal direction.
An der Nabe ist nach einer vorteilhaften Weiterbildung ein Zugmittel be- festigt, das zwischen den beiden Zahnscheiben des Zahnrades, durch den Schlitz in der Zahnstange und durch das Innere der Feder verläuft und an dem Widerlager befestigt ist. Die Konstruktion ist nach einer bevorzugten Ausgestaltung so ausgelegt, dass eine Drehung des Zahnrades ein Auf- bzw. Abwickeln des Zugmittels bewirkt, wodurch die Verstellung des Widerlagers erfolgt.According to an advantageous development, a traction means is fastened to the hub, which runs between the two toothed disks of the gear wheel, through the slot in the toothed rack and through the interior of the spring and is fastened to the abutment. According to a preferred embodiment, the construction is designed such that rotation of the gearwheel causes the traction means to be wound up or unwound, as a result of which the abutment is adjusted.
Weiterhin ist das Zugmittel vorteilhafterweise über eine Umlenkrolle geführt, die zwischen der Nabe und der Zahnstange angeordnet ist.Furthermore, the traction means is advantageously guided over a deflection roller which is arranged between the hub and the rack.
In die Umlenkrolle kann nach einer vorteilhaften Weiterbildung eine zusätzliche Über- oder Untersetzung integriert sein, ggf. mit veränderlichem Radius.According to an advantageous development, an additional step-up or step-down ratio can be integrated into the deflection roller, possibly with a variable radius.
Alternativ zur Verstellung des Widerlagers über ein Zugmittel kann an dem Widerlager nach einer vorteilhaften Ausgestaltung auch eine Gewindespindel angeordnet sein, die über die Motor-Getriebe-Einheit antreibbar ist, so dass das Widerlager direkt von der Motor-Getriebe-Einheit verstellt werden kann.As an alternative to adjusting the abutment by means of a traction device, a threaded spindle can also be arranged on the abutment according to an advantageous embodiment, which threaded spindle can be driven via the motor-gear unit, so that the abutment can be adjusted directly by the motor-gear unit.
Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus nachfolgender Beschreibung anhand der Zeichnung.Further details, features and advantages of the invention will become apparent from the following description with reference to the drawing.
Die einzige Figur zeigt den prinzipiellen Aufbau eines erfindungsgemäßen Türantriebes.The single figure shows the basic structure of a door drive according to the invention.
Der erfindungsgemäße elektromechanisch angetriebene Türantrieb weist einen Motor 1 auf, der mit einem Zahnrad 2 in Wirkverbindung steht. Das Zahnrad 2 besteht aus zwei zueinander parallelen Zahnscheiben 3, 4, die mittels einer Nabe miteinander verbunden sind, die eine in ihrem Radius veränderliche Kontur aufweist. Zwischen den beiden Zahnscheiben 3, 4 ist somit ein Schlitz gebildet. Das Zahnrad 2 bzw. die beiden Zahnscheiben 3, 4 kämmen mit einer Zahnstange 5, die mit einem längsverlaufenden Schlitz 6 versehen ist.The electromechanically driven door drive according to the invention has a motor 1 which is operatively connected to a toothed wheel 2. The gearwheel 2 consists of two toothed disks 3, 4 which are parallel to one another and which are connected to one another by means of a hub which has a contour which is variable in its radius. A slot is thus formed between the two toothed disks 3, 4. The toothed wheel 2 or the two toothed disks 3, 4 mesh with a toothed rack 5 which is provided with a longitudinal slot 6.
Der Türantrieb weist weiterhin eine als Energiespeicher dienende Feder 7 auf, die sich mit ihrem einen Ende an der Zahnstange 5 und mit ihrem anderen Ende an einem verstellbaren Widerlager 8 abstützt.The door drive also has a spring 7 serving as an energy store, which is supported at one end on the rack 5 and at the other end on an adjustable abutment 8.
Die Feder 7 ist in einem Gehäuse 9 gelagert, das sich im dargestellten Ausführungsbeispiel parallel zur Längsachse des Motors 1 erstreckt.The spring 7 is mounted in a housing 9 which extends parallel to the longitudinal axis of the motor 1 in the exemplary embodiment shown.
Weiterhin ist eine Umlenkrolle 10 vorgesehen, welche zwischen dem Zahnrad 2 und der Zahnstange 5 angeordnet ist.Furthermore, a deflection roller 10 is provided, which is arranged between the gear 2 and the rack 5.
An der Nabe zwischen den beiden Zahnscheiben 3, 4 ist ein Zugmittel 11 befestigt, das in dem Schlitz zwischen den beiden Zahnscheiben 3, 4 geführt ist, dann über die Umlenkrolle 10, durch den Schlitz 6 in der Zahnstange 5 und durch die Feder 7 bis zu dem Widerlager 8 verläuft und dort befestigt ist.On the hub between the two toothed disks 3, 4, a traction means 11 is fastened, which is guided in the slot between the two toothed disks 3, 4, then over the deflection roller 10, through the slot 6 in the rack 5 and through the spring 7 to runs to the abutment 8 and is fastened there.
In die Umlenkrolle 10 kann eine zusätzliche Über- oder Untersetzung integriert sein.An additional step-up or step-down ratio can be integrated into the deflection roller 10.
Durch einen Versatz der Mitten von Zahnstange 5 und Feder 7 kann ggf. auf die Schlitzung verzichtet werden, ggf. mit veränderlichem Radius.By displacing the centers of the toothed rack 5 and spring 7, the slitting can be dispensed with, if necessary with a variable radius.
Der erfindungsgemäße Türantrieb ist entweder für die Verwendung mit einem Scherengestänge oder einer Gleitschiene ausgelegt. Der Drehmomentenverlauf wird durch eine von dem Motor 1 bewirkte Veränderung der Vorspannung der Feder 7 verändert. Dies geschieht im dargestellten Ausführungsbeispiel durch eine Drehung des Zahnrades 2, wodurch das Zugmittel 11 auf die in ihrem Durchmesser veränderliche Nabe auf- bzw. abgewickelt wird und dadurch das Widerlager 8 der Feder 7 verstellt. Somit ändert sich auch die Vorspannung der Feder 7. Durch die im Radius veränderliche Kontur der Nabe kann folglich der Drehmomentenverlauf gesteuert und dem jeweiligen Übertragungsmechanismus (Scherengestänge oder Gleitschiene) angepasst werden. Somit unterscheiden sich diese Antriebsvarianten ausschließlich durch die eingesetzte Nabe mit der entsprechenden Kontur.The door drive according to the invention is designed either for use with a scissor linkage or a slide rail. The torque curve is changed by a change in the bias of the spring 7 caused by the motor 1. This is done in the illustrated embodiment by rotating the gear 2, whereby Traction means 11 is wound up or unwound onto the hub, which is variable in diameter, and thereby adjusts the abutment 8 of the spring 7. The preload of the spring 7 thus also changes. The contour of the hub, which can vary in radius, can consequently be used to control the torque curve and to adapt it to the respective transmission mechanism (scissor linkage or slide rail). Thus, these drive variants differ only in the hub used with the corresponding contour.
Anstatt - wie beschrieben - kann die Vorspannung der Feder 7 auch über ein im Getriebe integriertes Zahnrad, über die mit einer Schließerwelle verbundene Abtriebswelle des Türantriebes oder durch eine auf einer Gewindespindel angeordnete Federabstützung, deren Antrieb über den Motor 1 oder eine Getriebewelle erfolgt, verändert werden. Damit ist aller- dings wegen der festen Kopplung zwischen Motorumdrehung und Federverstellung keine Variantenbildung möglich. Instead of - as described - the preload of the spring 7 can also be changed via a gear integrated in the gear, the output shaft of the door drive connected to a closer shaft or a spring support arranged on a threaded spindle, which is driven by the motor 1 or a gear shaft . However, because of the fixed coupling between motor rotation and spring adjustment, no variant formation is possible.
