Abstract
Description
Die Erfindung betrifft einen Türschließer entsprer LThe invention relates to a door closer L entsprer
dem Oberbegriff des Anspruchs 1.the preamble of claim 1.
Es ist bekannt, insbes. bei Krankenhaus-Zimmertüren ohne Türdrücker automatische Türschließer zu verwenden.It is known, especially for hospital room doors without lever handles to use automatic door closers.
Diese Türschließer arbeiten hydraulisch, fangen beim Schließen der Tür das Türblatt ab und bewegen es auf dem letzten Teil des Schließwegs selbsttätig in die Schließstellung. Diese Türschließer sind in der Mitte der oberen horizontalen Türkante angebracht. Nachteilig ist bei solch einem Türschließer neben dem mechanischen Aufwand die Tatsache, daß das Türblatt eine hohe Verwindungssteifigkeit haben muß, da der Schließdruck nur an einer Stelle, nämlich in der Mitte der Türoberkante, ausgeübt wird. Das Türblatt muß daher eine erhebliche Dicke haben, so daß solche Türen schwer und teuer sind.These door closers work hydraulically and start when the door closes Unlock the door leaf and move it automatically on the last part of the closing path in the closed position. These door closers are in the middle of the top horizontal Door edge attached. A disadvantage of such a door closer is in addition to the mechanical one Effort the fact that the door leaf must have a high torsional stiffness, as the closing pressure is only applied at one point, namely in the middle of the top edge of the door, is exercised. The door leaf must therefore have a considerable thickness, so that such Doors are heavy and expensive.
Der Erfindung liegt die Aufgabe zugrunde, einen Türschließer zu schaffen, der ein leichtes Schließen der Tür und die Verwendung von leichten, dünnen Türblättern ermöglicht.The invention is based on the object of creating a door closer, the easy closing of the door and the use of light, thin door leaves enables.
Gelöst wird diese Aufgabe gemäß der Erfindung durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale. Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved according to the invention by the in the characterizing Part of claim 1 specified features. Appropriate embodiments of the invention result from the subclaims.
Beim Schließvorgang der Tür kommen die Permanentmagnete in eine Lage, in der sie sich gegenüberliegen. Da sich dabei gleiche Pole gegenüberliegen, stoßen sich die Magnete ab; da sie in Richtung der Abstoßkräfte nicht ausweichen können, sondern nur quer dazu, genügt ein geringer Kraftaufwand in Schließrichtung der Tür, um mittels der abstoßenden Magnetkräfte der Magnete ein automatisches Schließen der Tür zu bewirken.When the door is closed, the permanent magnets come into a position in which they face each other. Since the same poles are opposite each other, they collide the magnets off; since they cannot evade in the direction of the repulsive forces, but only across it, a small amount of force is sufficient in the closing direction of the door, to automatically close by means of the repelling magnetic forces of the magnets to effect the door.
Die Ausbildung der Magnete als flächenmäßig polarisierte Stabmagnet ermöglicht es, solche Magnete huber die gesamte Vertikalkante des Türfalzes des Türblatts und der Türzarge und ggf. auch in deren Horizontalkanten anzuordnen. Dadurch erreicht man, daß der Schließdruck nicht nur an einer Stelle wirkt, also das Türblatt keine hohe Verwindungssteifigkeit haben muß. Man kann daher relativ dünne, leichte Türblätter verwenden.The formation of the magnets as area-wise polarized bar magnets makes it possible to have such magnets over the entire hubs Vertical edge of the Door rebate of the door leaf and the door frame and possibly also in their horizontal edges to arrange. This achieves that the closing pressure is not only at one point acts, so the door leaf does not have to have a high torsional stiffness. One can therefore Use relatively thin, light door leaves.
Sowohl im Türfalz als auch in der Türzarge können in üblicher Weise Dichtungen angeordnet sein, um eine Geräuschdämpfung zu erreichen.Both in the door rebate and in the door frame can in the usual way Seals be arranged in order to achieve a noise attenuation.
Die Permanentmagnete können in Nuten angeordnet und durch Abdeckieisten abgedeckt sein, so daß sie das Aussehen der Tür nicht beeinträchtigen und gegen Beschädigungen geschützt sind.The permanent magnets can be arranged in grooves and covered with strips be covered so that they do not affect the appearance of the door and against Damage are protected.
Die Erfindung wird nachstehend anhand der anliegenden Zeichnung beispielsweise erläutert, die einen Horizontalschnitt der Tür im Bereich der Türzarge zeigt.The invention is illustrated below with reference to the accompanying drawing, for example explained, which shows a horizontal section of the door in the area of the door frame.
Das Türblatt 11 ist in der geschlossenen Stellung gezeigt. Im Türfalz 14 des Türblattes 11 ist im Bereich der Vertikalkante ein Permanentmagnet 15 angeordnet.The door leaf 11 is shown in the closed position. In the door rebate 14 of the door leaf 11, a permanent magnet 15 is arranged in the area of the vertical edge.
Ebenso ist im Bereich der Vertikalkante der Türzarge 13 des Türstocks 12 ein Permanentmagnet 15 angeordnet.Likewise, the door frame 13 of the door frame is in the area of the vertical edge 12 a permanent magnet 15 is arranged.
Wie gezeigt ist, sind die Permanentmagnete in der Schließstellung der Tür quer zur Nord-Süd-Richtung der Pole der Permanentmagnete 15 versetzt. Die Permanentmagnete 15 sind als flächenmäßig polarisierte Stabmagnete ausgebildet und die.Nordpole sind einander zugewandt.As shown, the permanent magnets are in the closed position the door transversely to the north-south direction of the poles of the permanent magnets 15 offset. the Permanent magnets 15 are designed as area-wise polarized bar magnets and the north poles face each other.
Beim Schließen der Tür kommen die Nordpole der Magnete 15 in eine Lage, in der sie einander gegenüberliernl.When the door is closed, the north poles of the magnets come out 15th in a position in which they face each other.
In diesem Falle sind die abstoßenden Magnetkräfte am größten. Da jedoch weder das Türblatt noch die Türzarge in Richtung der abstoßenden Kräfte ausweichen können, ist das Türblatt bestrebt, seitlich auszuweichen. Es genügt daher eine relativ geringe Kraft, um das Türblatt in die Schließstellung zu bringen. Gleiches gilt auch für das öffnen der Tür.In this case the repulsive magnetic forces are greatest. However, since neither the door leaf nor the door frame evade in the direction of the repulsive forces can, the door leaf tries to evade sideways. A relative is therefore sufficient little force to bring the door leaf into the closed position. same for also for opening the door.
Sowohl Türblatt als auch Türzarge können in üblicher Weise Dichtungen zur Geräuschdämpfung aufweisen.Both the door leaf and the door frame can seal in the usual way for noise reduction.
