Description
Die Erfindung betrifft einen Türschließer nach dem Oberbegriff des Anspruchs 1.The The invention relates to a door closer the preamble of claim 1.

Der in Anspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, einen Türschließer zu schaffen, der für den Schließvorgang ein großes Moment erzeugt, gleichzeitig jedoch für den Öffnungsvorgang ein relativ kleines Moment benötigt, ohne hierfür Fremdenergie einzusetzen.Of the The invention defined in claim 1 is based on the object, to create a door closer, the for the closing process a big Moment generated, but at the same time for the opening process a relative little moment needed without this Use external energy.
Diese Aufgabe wird durch einen Türschließer mit den Merkmalen des Anspruchs 1 gelöst.These Task is through a door closer with the features of claim 1 solved.
Der Kern dieser Erfindung besteht darin, daß die feste Kopplung zwischen Öffnungs- und Schließkraft aufgehoben wird. Beim Öffnungsvargang und beim ersten Teil des Schließvorganges hat das zusätzliche Getriebe eine Kraftübersetzung von Ü = 1. Dann folgt ein weiterer Teil des Schließvorganges, bei dem die Kraftübersetzung Ü < 1 ist, d. h. das Schließmoment wird verringert. Im dritten Teil des Schließvorganges, in dem die Tür ins Schloß gezogen wird, ist die Kraftübersetzung Ü > 1 d. h. das Schließmoment ist deutlich größer als das Öffnungsmoment. Hierbei wird die zusätzliche Übersetzung durch ein hydraulisches Getriebe realisiert, was kompakte und einfache Lösungen ermöglicht.Of the The essence of this invention is that the fixed coupling between opening and closing force will be annulled. At the opening process and at the first part of the closing process has the extra Transmission a power transmission from Ü = 1. Then follows a further part of the closing process, in which the force transmission is Ü <1, d. H. the closing moment is reduced. In the third part of the closing process, in which the door is pulled into the lock is, the force transmission is Ü> 1 d. H. the closing moment is significantly larger than the opening moment. Here is the additional translation by realized a hydraulic transmission, which is compact and simple solutions allows.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.advantageous Embodiments of the invention are specified in the subclaims.
Ausführungsbeispiele sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben:embodiments are shown in the drawings and are described in more detail below:

- a
- actual closing range with high torque requirement (≅ 5 °)
- b
- Passage region
- c
- Installation area (≅ 130 °)
Diese
Kraftübersetzungen

Mit diesem Momentenverlauf ist die Aufgabe gelöst: Das Schließmoment Ms1 ist im Schließbereich deutlich höher als das Öffnungsmoment Mö. Dieser Lösungsansatz eines nachgeschalteten Getriebes soll anhand einer hydraulischen Lösung demonstriert werden.With this torque curve, the problem is solved: the closing moment M s1 is significantly higher in the closing area than the opening moment M ö . This solution approach of a downstream transmission is to be demonstrated by means of a hydraulic solution.

Der Hauptvorteil dieser Lösung ergibt sich daraus, daß durch die Wahl der Verdrängerflächen beliebige Übersetzungsverhältnisse gebildet werden können.Of the Main advantage of this solution it follows from that by the choice of displacement surfaces arbitrary ratios can be formed.
