Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand der vorliegenden Erfindung bildet eine Vorrichtung zum Öffnen und
Schließen von Oberlichtflügeln mit einer mittels Schubstange angetriebenen Hebelschere.
S Neu ist, daß die in bekannter Weise mit einem Hebelarm gelenkig verbundene Schubstange
durch ein gelenkiges Zwischenglied auch mit dem anderen Hebelarm in Verbindung
steht, derart, daß beim Beginn der Öffnungsbewegung beide Hebelarme annähernd gleichmäßig
angetrieben werden.The subject of the present invention is a device for opening and closing skylight sashes with lever scissors driven by means of a push rod.
What is new is that the push rod, which is articulated in a known manner with a lever arm, is also connected to the other lever arm by an articulated intermediate member, in such a way that both lever arms are driven approximately evenly at the beginning of the opening movement.

Diese Vorrichtung besteht aus den in bekannter Weise angeordneten beiden Hebelpaaren α α und Ct1 au die durch die Bolzen b und c miteinander in Verbindung stehen. Die über den Drehpunkt c hinausgehenden Hebelarme der Teile α und Ci1 sind mit ν und V1 bezeichnet. Am Arm ν greift in bekannter Weise die wagerechte Stange h an, während der Arm V1 in ebenfalls bekannter Weise am Fenstergewände angelenkt ist. Mit der Stange h ist ein Glied g mittels Bolzens f gelenkig verbunden, dessen anderes Ende mittels Bolzens i am Scherenteil U1 angelenkt ist. Das andere Ende der Stange h ist an dem Winkelhebel w angelenkt, der um einen am Gewände festen Punkt drehbar gelagert ist. Dieser Winkelhebel wird durch eine in bekannter Weise mittels Handhebels χ und Lenkers ^1 senkrecht verschiebbare Schubstange % bewegt. Durch die Einschaltung des Gliedes g zwischen Schubstange h und dem der Stange zunächst liegenden Hebelarm α, soll erreicht werden, daß zu Beginn der Öffnungsbewegung (und dementsprechend auch gegen Ende der Schließbewegung) ein Teil der zum Bewegen des Flügels erforderlichen Kraft auf den Hebel CL1 übertragen und somit eine annähernd gleichmäßige Beanspruchung der beiden dem Gewände zugekehrten Scherenhebel α und Ci1 erzielt wird.This device consists of the two pairs of levers α α and Ct 1 a u, which are arranged in a known manner and which are connected to one another by the bolts b and c. The lever arms of parts α and Ci 1 extending beyond the pivot point c are denoted by ν and V 1. The horizontal rod h acts on the arm ν in a known manner, while the arm V 1 is hinged to the window walls in a likewise known manner. A link g is articulated to the rod h by means of a bolt f , the other end of which is hinged to the scissor part U 1 by means of a bolt i. The other end of the rod h is hinged to the angle lever w , which is rotatably mounted about a point fixed on the wall. This angle lever is moved by a push rod % which can be moved vertically in a known manner by means of a hand lever χ and handlebar ^ 1. By interposing the link g between the push rod h and the lever arm α that lies next to the rod, at the beginning of the opening movement (and accordingly also towards the end of the closing movement) part of the force required to move the sash is applied to the lever CL 1 transferred and thus an approximately uniform stress on the two scissor levers facing the walls α and Ci 1 is achieved.
