Description

Die Erfindung geht aus von einem Türschließer gemäß dem Oberbegriff des Anspruches 1.The invention is based on a door closer according to the preamble of claim 1.

Ein solcher Türschließer ist unter der Bezeichnung "DORMA TS 77" bekannt geworden und hat sich in der Praxis durch seine Zuverlässigkeit und die vielfältigen Anwendungsmöglichkeiten bewährt. Der Türschließer kann sowohl an der Innen- oder Außenseite eines Türblattes als auch an einem Türrahmen montiert werden. Die Anordnung des Türschließers an der Innenseite eines Türblattes ist grundsätzlich problematisch, da das Türblatt beim Öffnen in Richtung der benachbarten Wand bewegt wird und der Türschließer sich dann zwischen dem Türblatt und dieser Wand befindet. Es besteht also die Gefahr, daß der Türschließer bei zu großem Öffnungswinkel des Türblattes gegen die benachbarte Wand stößt und beschädigt wird, insbesondere sofern die Tür in einer Raumecke oder einer dickwandigen Mauer eingebaut ist. Bei derartigen Anwendungsfällen ist eine Begrenzung des Öffnungswinkels angebracht. Erstrebenswert sind deshalb kompakte Türschließer mit geringstmöglicher Bauhöhe unter Beibehaltung der bisherigen Anwendungsvielfalt und der unterschiedlichen Funktionen.Such a door closer is known under the name "DORMA TS 77" has become and in practice due to its reliability and the diverse application options have proven their worth. The door closer can both on the inside or outside of a door leaf be mounted on a door frame. The arrangement of the door closer the inside of a door leaf is fundamentally problematic because that Door leaf is moved towards the adjacent wall when opening and the door closer then between the door leaf and this wall located. So there is a risk that the door closer is too large Opening angle of the door leaf bumps against the adjacent wall and is damaged, especially if the door is in a corner of the room or a thick-walled wall is installed. In such applications a limitation of the opening angle is appropriate. Desirable are therefore compact door closers with the lowest possible height under Maintaining the previous variety of applications and the different Functions.

Die Außenabmessungen, insbesondere die Bauhöhe, des bekannten Türschließers sind aufgrund des speziellen Innenaufbaus sehr hoch, so daß für die Verpackung des Türschließers entsprechend viel Verpackungsmaterial benötigt wird und des weiteren entsprechender Lager- und Transportraum zur Verfügung stehen muß. Die kantige Außenform des Türschließers schafft fertigungstechnische Probleme durch Materialhohlräume und ist unter dem Aspekt eines ökonomischen Materialeinsatzes nicht optimal.The external dimensions, in particular the overall height, of the known door closer are very high due to the special internal structure, so that a lot of packaging material for the packaging of the door closer is required and furthermore appropriate storage and transport space must be available. The angular outer shape of the door closer creates manufacturing problems due to material cavities and is under the aspect of an economical use of materials not optimal.

Aus der FR 2 319 761 A und der DE 2 245 748 A sind Türschließer bekannt, deren Außenformen hinsichtlich des Materialeinsatzes optimiert worden sind. Die übereinander liegende Anordnung der Welle und einer außen verzahnten Zahnstange innerhalb des Türschließergehäuses lassen aufgrund der systembedingten Grenzen eine wesentliche Verringerung der Bauhöhe jedoch nicht zu.Door closers are known from FR 2 319 761 A and DE 2 245 748 A, their outer shapes optimized with regard to the use of materials have been. The superimposed arrangement of the shaft and one Leave the toothed rack inside the door closer housing a significant reduction due to the system-related limits the height does not increase.

Aus der US-A-4 394 787 ist ebenfalls ein derartiger Türschließer bekannt. Die Welle des Türschließers ist bei dieser Ausführungsform in Lagerböcken gelagert, die über das Türschließergehäuse vorstehen und sich dadurch eine optisch wenig ansprechende Ausgestaltung ergibt.Such a door closer is also known from US-A-4,394,787. The shaft of the door closer is in this embodiment in bearing blocks stored, which protrude beyond the door closer housing and themselves this results in an optically unappealing design.

Der Erfindung liegt die Aufgabe zugrunde, einen Türschließer nach dem Oberbegriff des Anspruches 1 so zu verbessern, daß eine kompakte und optisch ansprechende Einheit entsteht, die mit minimalen Material- und Fertigungsaufwand hergestellt werden kann.The invention has for its object a door closer according to the Preamble of claim 1 to improve so that a compact and optically appealing unit arises with minimal material and Manufacturing effort can be made.

Gelöst wird diese Aufgabe mit den im kennzeichenden Teil des Anspruches 1 angegebenen Merkmalen. Weitere vorteilhafte Ausgestaltungen der Erfindung sind durch die Unteransprüche gekennzeichnet.This problem is solved with the in the characterizing part of the claim 1 specified characteristics. Further advantageous configurations the invention are characterized by the subclaims.

Der Gegenstand des Anspruches 1 weist den Vorteil auf, daß durch die kompakte Außenform des Türschließers eine geringe Bauhöhe realisiert werden kann. Der Türschließer ist damit auch für die Verwendung unter beengten bzw. ungünstigen Einbausituationen hinsichtlich eines eingeschränkten Öffnungswinkels eines Türblattes geeignet. Grundsätzlich ist hierbei ein Türschließer zu bevorzugen, dessen mechanische und hydraulische Einheiten in Längsrichtung in einem entsprechenden Kanal des Körpers angeordnet sind.The object of claim 1 has the advantage that compact outer shape of the door closer realized a low height can be. The door closer is therefore also suitable for use under cramped or unfavorable installation situations with regard to a restricted Opening angle of a door leaf suitable. Basically is to prefer a door closer, its mechanical and hydraulic Units in the longitudinal direction in a corresponding channel of the body are arranged.

Obwohl der Materialbedarf für den erfindungsgemäßen Körper äußerst gering ist, sind die Stabilitäts- und alle Funktionseigenschaften gewährleistet. Alle Wanddicken sind auf ein Minimum reduziert. Die sich ergebenden Außenkonturen werden durch fließende und nahtlose Übergänge optisch ansprechend gestaltet. Der Körper ist durch die Reihenanordnung der Funktionseinheiten länglich geformt, wobei sich die Seitenflächen an die Konturen des Kanals anschmiegen. Ideal ist dabei ein gekrümmter oder schräger Verlauf der Seitenflächen. Der fließende Verlauf der Außenkonturen, insbesondere der Seitenflächen und der nachfolgend erläuterten Lagerblöcke, reduziert den Materialeinsatz erheblich und vermindert die gießtechnischen Probleme.Although the material requirements for the body according to the invention are extreme is low, the stability and all functional properties are guaranteed. All wall thicknesses are reduced to a minimum. The resulting Outside contours are created by flowing and seamless transitions visually appealing. The body is through the row arrangement of the functional units elongated, the side faces nestle the contours of the channel. A curved one is ideal or oblique course of the side surfaces. The flowing course of the outer contours, especially the side surfaces and the ones explained below Bearing blocks, significantly reduces and reduces the use of materials the casting problems.

Damit die Austrittsstellen der Antriebswelle hinreichend stabil sind, weisen die Seitenflächen blockartige massive Verstärkungen auf, die ihrerseits materialsparend ausgebildet sind. Besonders vorteilhaft ist die Anbindung dieser sogenannten Lagerblöcke an der Unterseite des Körpers. Die Antriebswelle ist so angeordnet, daß verschiedene Montagepositionen des Türschließers realisiert werden können.So that the exit points of the drive shaft are sufficiently stable the side faces block-like massive reinforcements, which in turn are designed to save material. The connection is particularly advantageous these so-called bearing blocks on the underside of the body. The drive shaft is arranged so that different mounting positions of the door closer can be realized.

Darüber hinaus ist die Welle äußerst materialsparend und montagefreundlich in der entsprechenden Achsbohrung gelagert und befestigt. In addition, the shaft is extremely material-saving and easy to assemble stored and fastened in the corresponding axle bore.

Die Reduzierung der Außenabmessungen vermindert die Menge an benötigten Verpackungsmaterialien und verringert den Lager- und Transportplatz. Die Reduzierung des Volumens und des Gewichtes erhöht die Packungsdichte während des Transportes und erleichtert darüberhinaus den Montagekräften vor Ort die Handhabung. Die genannten Eigenschaften tragen außerdem wesentlich zur Reduzierung der Herstellungskosten bei.The reduction in the external dimensions reduces the amount of required Packaging materials and reduces the storage and transport space. The reduction in volume and weight increases the Packing density during transport and also facilitates handling on site by the assembly staff. The properties mentioned also contribute significantly to reducing manufacturing costs at.

In den Figuren sind gleiche oder gleichwirkende Bauteile mit gleichen Bezugsziffern dargestellt. Die in den Figuren dargestellten Türschließer 1 werden einstückig in einem Gießprozess hergestellt und bestehen z. B. aus Aluminium oder Stahl. Trotz des Aspektes der Optimierung von minimalem Materialeinsatz bei hinreichender Körperstabilität entsteht kein massiver Körper 2. Grundsätzlich sind alle Außenkonturen und Flächenübergänge abgerundet ausgebildet.In the figures, the same or equivalent components are the same Reference numbers shown.

Die Türschließer 1 sind jeweils zur Aufnahme einer mechanischen und einer hydraulischen Funktionseinheit ausgerüstet, die zur Verringerung der Bauhöhe in bekannter Weise in Längserstreckung des Körpers 2 in einem Kanal 21 angeordnet sind. Eine Welle 22 verbindet die mechanische Einheit in dem Körper 2 mit einem Gestänge außerhalb des Körpers 2. Die Welle 22 wird beiderseits aus dem Körper 2 geführt, um die Anordnung des Türschließers 1 und des Gestänges, bezogen auf ein Türblatt und ein Türrahmen in Abhängigkeit von den Montagebedingungen variabel handhaben zu können. Aus Gründen der Übersichtlichkeit ist das Gestänge nicht dargestellt.The door closers 1 are each for receiving a mechanical and a hydraulic functional unit equipped to reduce the height in a known manner in the longitudinal extent of the body 2 in a channel 21 are arranged. A shaft 22 connects the mechanical Unit in the body 2 with a linkage outside the body 2.

The shaft 22 is outside the body 2 with that, not shown Linkage coupled.

Wenn die Tür geöffnet wird, wird die Welle 22 über das mit der Tür gekoppelte Gestänge verdreht. Der Kolben 23 wird in horizontaler Richtung bewegt und drückt die Schließerfeder 24 zusammen. Die gespeicherte Öffnungsenergie wird, sobald die Tür losgelassen wird, wieder frei, indem sich die Schließerfeder 24 entspannt und dabei den Kolben 23 in die entgegengesetzte Richtung drückt. Die Tür wird durch die Umsetzung der linearen Bewegung in eine Drehbewegung wieder geschlossen. Als Dämpfungsmedium befindet sich in dem Körper 2 Hydrauliköl.When the door is opened, the shaft 22 is coupled to that coupled to the door Linkage twisted. The piston 23 is in the horizontal direction moves and compresses the closer spring 24. The saved As soon as the door is released, opening energy is released again by the closer spring 24 relaxes and the piston 23 in the opposite direction Direction presses.
