Description
Türschliesser mit schwenkbarem Zylinder. Gegenstand der vorliegenden Erfindung ist ein Türschliesser mit um eine Vertikal achse schwenkbarem Zylinder, in welchem ein Steuerkolben gleitet, dessen Stange in Triebverbindung mit einem am Türflügel zu befestigenden, als Lagerzapfen für denselben bestimmten Drehzapfen steht.
Derselbe zeichnet sich nach der Erfindung dadurch aus, dass der genannte Drehzapfen einen segmentartigen Bewegungsübertra- gungsteil trägt, der mehrere Kupplungsstel len für die genannte Kolbenstange aufweist, so dass letztere je nach dem Öffnungssinn des Türflügels, an dem der Türschliesser anzu bringen ist, mit der einen oder mit der andern dieser Kupplungsstellen in Eingriffsverbin- dung gebracht werden kann.
Auf der beiliegenden Zeichnung ist ein Ausführungsbeispiel des Erfindung3gegen- standes veranschaulicht.
I\ig. 1 ist ein Längsschnitt durch einen im Boden versenkten Türschliesser, und Fig. 2 ist eine Oberansicht auf den Tür schliesser, mit einzelnen im Schnitt darge stellten Stellen. a ist ein im Boden versenktes Gehäuse des Türschliessers, der einen Zylinder b und einen in diesen gleitenden Steuerkolben c mit Kol benstange cl aufweist. Der Zylinder b ist an seinem der Kolbenstange cl abgewendeten Ende um einen im Gehäuse a befestigten Ver tikalbolzen a1 schwenkbar angeordnet.
Am andern Ende des Gehäuses a ist mittels eines Spurlagers d und eines Halslagers dl ein die eine Lagerstelle des Türflügels e bildender Drehzapfen f gelagert, der mit letzterem fest verbunden ist. Dieser Drehzapfen trägt einen segmentartigen Bewegungsübertragungsteil g, der mit drei Kupplungslöchern g1, g2, g3 ver sehen ist, mit welchen das abgebogene Ende der Kolbenstange c1 in Eingriff gebracht werden kann.
Der Steuerkolben c steht unter dem Einfluss einer Schraubenfeder i, die ihn nach innen zu bewegen trachtet. Die weitere Ausbildung und die Funktionsweise der Kol benvorrichtung sind bekannt, so dass es er übrigen dürfte, näher darauf einzutreten. Es sei lediglich daran erinnert, dass das Druck fluidum (z. B.
Drucköl) beim Öffnen der Türe im Sinne des in Fig. 2 eingezeichneten Pfeils infolge des nach vorn bewegten Kol bens cl durch ein in letzterem vorgesehenes Durchlassventil h hindurchgetrieben wird und anlässlich der Rückführungsbewegung des Kolbens durch die Leitung m wieder auf die andere Kolbenseite gelangt.
Wie oben erwähnt, weist der segment- artig.e Teil drei Kupplungslöcher auf. Im ge zeichneten Ausführungsbeispiel ist die Kol benstange ei in Eingriff mit dem Loch g1, da es sich um eine Türe handelt, die nur im Sinne des eingezeichneten Pfeils geöffnet wird. Handelt es sich um eine Türe, die im entgegengesetzten Sinne geöffnet wird, so wird die Kolbenstange c' mit dem Loch g3 in Eingriff gebracht. Das mittlere Loch ,g\ dient als Kupplungsstelle, wenn die Türe z. B. als sogenannte Windfangtüre nach bei den Richtungen geöffnet werden kann.
Dank der beschriebenen Ausbildung des segment- artigen Teils g lässt sich somit der Tür schliesser an den Öffnungssinn der Türe an passen und kann daher in jedem. Falle ver wendet werden.
Door closer with swiveling cylinder. The present invention relates to a door closer with a cylinder pivotable about a vertical axis, in which a control piston slides, the rod of which is in drive connection with one to be attached to the door leaf, as a bearing pin for the same particular pivot pin.
The same is characterized according to the invention in that said pivot pin carries a segment-like movement transmission part which has several coupling points for said piston rod, so that the latter, depending on the opening direction of the door leaf on which the door closer is to be attached, with the one or the other of these coupling points can be brought into engagement.
An exemplary embodiment of the subject of the invention is illustrated in the accompanying drawing.
I \ ig. 1 is a longitudinal section through a sunk in the floor door closer, and Fig. 2 is a top view of the door closer, with individual points in section Darge presented. a is a sunk in the floor housing of the door closer, which has a cylinder b and a control piston c sliding in this with Kol rod cl. The cylinder b is arranged at its end facing away from the piston rod cl about a vertical bolt a1 fastened in the housing a.
At the other end of the housing a, a pivot pin f, which forms a bearing point of the door leaf e and is firmly connected to the latter, is mounted by means of a thrust bearing d and a neck bearing dl. This pivot pin carries a segment-like motion transmission part g, which is seen ver with three coupling holes g1, g2, g3 with which the bent end of the piston rod c1 can be brought into engagement.
The control piston c is under the influence of a helical spring i, which tries to move it inward. The further training and mode of operation of the Kol benvorrichtung are known, so that it is likely that the rest of them to step closer to it. It should only be remembered that the pressure fluidum (e.g.
Pressure oil) is driven through a valve h provided in the latter when the door is opened in the sense of the arrow drawn in FIG. 2 as a result of the forward moving piston cl and returns to the other piston side on the occasion of the return movement of the piston through the line m.
As mentioned above, the segment-artig.e part has three coupling holes. In the embodiment shown, the piston rod egg is in engagement with the hole g1, since it is a door that is only opened in the direction of the arrow shown. If it is a question of a door that is opened in the opposite direction, the piston rod c 'is brought into engagement with the hole g3. The middle hole, g \ serves as a coupling point when the door z. B. can be opened as a so-called vestibule door according to the directions.
Thanks to the described design of the segment-like part g, the door can therefore be adapted to the opening direction of the door and can therefore be used in everyone. Trap can be used.
