Description

Titel: Anordnung für das Öffnen und Schließen einer Tür oder eines ToresTitle: Arrangement for opening and closing a door or gate
Beschreibungdescription
Die Erfindung betrifft eine Anordnung für das Öffnen und Schließen einer Tür gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an arrangement for opening and closing a door according to the preamble of claim 1.
Bekannte Anordnungen dieser Art umfassen einen Türschließer mit einer Schließfeder, dessen Kolben über eine Verzahnung mit der auf ein zu der zu betätigenden Tür führendes Gestänge einwirkenden Schließerwelle in Eingriff steht, sowie eine mit dem ohnehin vorhandenen Dämpfungsme- dium des Türschließers arbeitende auf den Kolben des Türschließers einwirkende hydraulische Antriebsvorrichtung, wobei über eine auf Sensoren ansprechende Steuer- und Regeleinheit das Öffnen und Schließen der betroffenen Tür gesteuert wird; vgl. US 4,995,194 und den Drehflügelantrieb DORMA ED200.Known arrangements of this type include a door closer with a closing spring, the piston of which engages via a toothing with the closer shaft, which acts on a linkage leading to the door to be actuated, and a door damping medium, which is present anyway, on the piston of the door closer acting hydraulic drive device, the opening and closing of the affected door being controlled via a control unit which responds to sensors; see. US 4,995,194 and the swing door operator DORMA ED200.
Da das Schließen der in unterschiedliche Öffnungswinkel überführbaren Tür allein über die beim Öffnungsvorgang gespannten Schließfeder des Türschließers erfolgt, sowie ein manuelles Öffnen der Tür ebenfalls möglich sein muss, sind relativ aufwendige mechanische Kupplungselemente zwischen Antrieb und Kolben des Türschließers notwendig, die zudem besondere Fertigkeit bei Montage und Service sowie der schaltwegege- nauen Einstellung bedürfen; vgl. EP 0 662 185 B1.Since the door, which can be converted into different opening angles, is closed solely via the closing spring of the door closer that is tensioned during the opening process, and manual opening of the door must also be possible, relatively complex mechanical coupling elements between the drive and the piston of the door closer are necessary, which are also particularly skillful during assembly and service as well as the switch path-exact setting; see. EP 0 662 185 B1.
Darüber hinaus ist ein hydraulischer Antrieb für das selbsttätige oder unterstützende Öffnen einer Tür infolge der notwendigen Hydraulikpumpe geräuschvoll, was beim Einsatz solcher Anordnungen in Krankenhäusern, Alters- und Pflegeheimen aus vielen Gründen unerwünscht ist.In addition, a hydraulic drive for the automatic or supportive opening of a door due to the necessary hydraulic pump is noisy, which is undesirable for many reasons when using such arrangements in hospitals, old people's homes and nursing homes.
Hier setzt nun die Erfindung ein, mittels der ein möglichst geräuscharmer Antrieb einer solchen Anordnung, die einen Türschließer herkömmlicher Bauart, einen Hilfsantrieb sowie eine Steuereinheit umfasst, geschaffen werden soll. Diese Aufgabe ist gemäß der Erfindung durch die Merkmale des Patentanspruches 1 gelöst.This is where the invention comes in, by means of which a drive of such an arrangement, which comprises a door closer of conventional design, an auxiliary drive and a control unit, should be as quiet as possible. This object is achieved according to the invention by the features of claim 1.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further features of the invention emerge from the subclaims.
Durch die direkte Kupplung des Kolbens des Türschließers mit einem elektromotorischen Antrieb werden nicht nur die aufwendigen mechanischen Kupplungselemente erübrigt, es entfällt auch die geräuschvolle Hydraulikpumpe. Die notwendigen Steuerschritte können elektronisch auf einfache Weise realisiert werden. Ist der Elektromotor stromlos geschaltet, lässt sich das Öffnen der Tür in üblicher Weise auch manuell durch- führen, da die geringen Reibungsverluste in der getrieblichen Verbindung die aufzuwendende Schließkraft nur unwesentlich erhöht. Die erfindungsgemäße Anordnung ermöglicht also auf überraschend einfache Weise einen sehr leisen, stufenlos schaltbaren Türantrieb.The direct coupling of the door closer piston with an electromotive drive not only eliminates the complex mechanical coupling elements, it also eliminates the noisy hydraulic pump. The necessary control steps can be implemented electronically in a simple manner. If the electric motor is switched off, the door can also be opened manually in the usual way, since the low frictional losses in the gear connection only increase the closing force to be exerted insignificantly. The arrangement according to the invention thus enables a very quiet, continuously switchable door drive in a surprisingly simple manner.
Die Erfindung ist nachfolgend anhand eines in der Zeichnung mehr oder minder schematisch dargestellten Ausführungsbeispiels beschrieben.The invention is described below with reference to an embodiment shown more or less schematically in the drawing.

Fig. 1 Ein nur teilweise dargestelltes Ausführungsbeispiel der Anordnung nach der Erfindung im Bereiche des an das Türschließergehäuse angeflanschten Antriebes.Fig. 1 An only partially illustrated embodiment of the arrangement according to the invention in the area of the drive flanged to the door closer housing.
Fig. 2 Eine Draufsicht auf den Antrieb nach Fig. 1 mit einem kombinierten Zahnrad-Zahnriemengetriebe zur Untersetzung der Drehzahl des Elektromotors.Fig. 2 is a plan view of the drive of FIG. 1 with a combined gear-toothed belt gear for reducing the speed of the electric motor.
Von einer insgesamt mit einer Bezugsziffer 10 bezeichneten Anordnung zum Öffnen und Schließen einer als Schwenk- oder Drehtür ausgebilde- ten Tür oder eines Tores ist in Fig. 1 lediglich ein Teil des einen mechanischen Türschließers ED üblicher Bauart umschließenden Gehäuses 12 dargestellt. Der Türschließer ED weist einen gegen eine nicht dargestellte Schließfeder wirkenden Kolben 13 auf. Dieser Kolben 13 ist in bekannter Weise über eine Verzahnung mit der ebenfalls nicht dargestellten Schlie- ßerwelle in Wirkverbindung, der über ein übliches Gestänge auf die zu betätigende Tür einwirkt. Der Kolben 13 ragt mit einem Fortsatz 15, der als integrales Teil des Kolbens 13 ausgebildet ist, durch eine einer nicht dargestellten Schließfeder abgewandten Stirnseite 16 des Gehäuses 12 und ist in einem Schiebelager 17 in Richtung des Doppelpfeiles V verschiebbar gelagert. Der Fort- satz 15 ist mit einer Verzahnung 18 versehen, in die ein Ritzel 19 eines auf einer Welle 21 eines insgesamt mit G bezeichneten Getriebes in Eingriff steht.Of an arrangement, generally designated by reference number 10, for opening and closing a door or gate designed as a pivoting or pivoting door, only part of the housing 12 enclosing a mechanical door closer ED of a conventional type is shown in FIG. 1. The door closer ED has a piston 13 acting against a closing spring, not shown. In known manner, this piston 13 is operatively connected via a toothing to the closer shaft, also not shown, which acts on the door to be actuated via a conventional linkage. The piston 13 projects with an extension 15, which is designed as an integral part of the piston 13, through an end face 16 of the housing 12 facing away from a closing spring, which is not shown, and is mounted in a sliding bearing 17 so as to be displaceable in the direction of the double arrow V. The extension 15 is provided with a toothing 18, in which a pinion 19 of a gear on a shaft 21 of an overall gear G is engaged.
Den Aufbau des Getriebes G zeigt im Einzelnen die Fig. 2. Auf der das mit dem Fortsatz 15 in Eingriff stehende Ritzel 19 tragenden Welle 21 ist ein weiteres Ritzel 23 angeordnet, das mit einem Zahnrad 24 kämmt, das auf einer Welle 25 sitzt, die über einen Zahnriementrieb 28 von einem Elektromotor 29 angetrieben ist.The structure of the transmission G is shown in detail in FIG. 2. On the shaft 21 carrying the pinion 19 which engages with the extension 15, a further pinion 23 is arranged, which meshes with a gear 24 which is seated on a shaft 25 which is driven by an electric motor 29 via a toothed belt drive 28.
Als Elektromotor 29 ist vorzugsweise ein über einen Frequenzumformer gespeister Asynchronmotor vorgesehen, es ist aber auch möglich, einen gesteuerten DC-Motor zu verwenden.An asynchronous motor fed via a frequency converter is preferably provided as the electric motor 29, but it is also possible to use a controlled DC motor.
Die der Übersicht halber nicht dargestellten weiteren Teile der Anordnung samt der zugehörigen Steuerung, auf die mittels üblicher Sensoren eingewirkt wird, sind üblicher Bauart und bedürfen daher auch keiner Beschreibung. For the sake of clarity, the other parts of the arrangement, including the associated control, which are acted on by means of conventional sensors, are of conventional construction and therefore do not require any description.
