KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Feststellvorrichtung für Dachlüfter, Oberlichtfenster u. dgl, bei der in die Rasten der an den Fensterflügel angelenkten Stellstange der eine Arm eines zweiarmigen Sperrgliedes eingreift, dessen einer Arm schwerer ist als der andere.The invention relates to a locking device for roof ventilators, skylight windows and the like, with the one arm in the notches of the control rod hinged to the window sash engages a two-armed locking member, one arm of which is heavier than the other.
Von bekannten Vorrichtungen dieser Art unterscheidet sich der Erfindungsgegenstand dadurch, daß der schwerere Arm des zweiarmigen Sperriegels zur Feststellung der Stellstange dient, während der leichtere Arm des Sperriegels stets an der Stellstange anliegt und von deren Gewicht derart beeinflußt wird, daß der schwerere Arm des Riegels stets in Eingriffslage gehalten wird, bis er beim Anheben der Stellstange durch sein Gewicht die selbsttätige Auslösung herbeiführt.The subject of the invention differs from known devices of this type in that the heavier arm of the two-armed locking bolt to fix the control rod serves, while the lighter arm of the locking bolt is always in contact with the control rod and is influenced by their weight in such a way that the heavier arm of the bolt is always in Engagement position is held until he lifts the control rod by his weight causes automatic release.
Diese Anordnung bietet den Vorteil äußerst einfacher und billiger Herstellung sowie bequemster Handhabung und es ist außerdem weitgehendste Sicherheit gegen unbeabsichtigte Verstellung des Fensters geboten, da selbst von unten gegen das geöffnete Fenster wirkende Kräfte kein Auslösen des Riegels ver-Ursachen können, weil dieser dabei durch die Druckwirkung der Stellstange auf seinen leichteren Arm erst recht in Sperrlage gehalten wird.This arrangement offers the advantage of extremely simple and inexpensive manufacture and also the most convenient Handling and it is also the greatest possible security against unintentional Adjustment of the window required, as it acts against the open window even from below Forces no triggering of the bolt can cause this, because this is done by the The pressure effect of the control rod on his lighter arm is kept in the locked position will.
Auf der Zeichnung ist die Neuerung durch Fig. ι in geöffneter undIn the drawing, the innovation is through Fig. Ι in open and
Fig. 2 in geschlossener Stellung beispielsweise veranschaulicht.Fig. 2 illustrates, for example, in the closed position.
Am Fensterrahmen α ist die übliche Stellstange b bei c drehbar angebracht und sie ist, wie bekannt, mit Rasten d versehen. An der Zarge e ist bei f ein Riegel g drehbar gelagert, dessen einer Arm in bekannter Weise schwerer ist als der andere. Gemäß der Erfindung wirkt jedoch der schwerere Arm h als Sperrarm, während der leichtere Arm stets an der Stellstange b anliegt. Bei geöffnetem Fenster hintergreift die Stellstange b mit einer ihrer Rasten d den Sperrarm h des Riegels g (Fig. 1).On the window frame α , the usual control rod b is rotatably attached at c and it is, as known, provided with notches d . On the frame e , a bolt g is rotatably mounted at f , one arm of which is heavier than the other in a known manner. According to the invention, however, the heavier arm h acts as a locking arm, while the lighter arm always rests on the control rod b . When the window is open, the control rod b engages behind the locking arm h of the bolt g with one of its notches d (Fig. 1).
Beim Schließen des Fensters braucht nur die Stellstange δ angehoben zu werden, worauf der Riegel g infolge der Schwere seines Armes h selbsttätig aus der jeweiligen Rast d der Stellstange b herausfällt, so daß die Stellstange b, die sich in einer Führung i bewegt, zwischen dieser und dem Riegel gleiten kann.When closing the window, only the control rod δ needs to be raised, whereupon the bolt g automatically falls out of the respective detent d of the control rod b due to the gravity of its arm h , so that the control rod b, which moves in a guide i , between this and the bolt can slide.
Beim Öffnen des Fensters drückt die Stellstange b den leichteren Arm des Riegels g abwärts und bringt dadurch dessen Sperrarm h mit der jeweils gewünschten Rast d der Stellstange b in Eingriff.When the window is opened, the actuating rod b presses the lighter arm of the bolt g downwards and thereby brings its locking arm h into engagement with the respectively desired detent d of the actuating rod b.
