Abstract (en)

A smoke and heat release roof hatch (1) has a spring-operated lever arm pushrod (7) mechanism that pivots (Po) the hatch (1) to open over a turret outlet (15). The pushrod is attached to a supporting lever (10) that swings thru a second pivot axis (P3). The two pivot points (Po, P3) are spaced apart. One end of a supplementary lever (11) is attached to the pushrod (7). One end of a tensile spring (14) is attached (17) to the turret (15) at a point that is further from the first pivot point (Po) than the drive (7) swivel axis (P2). The other end of the spring (14) is attached to the lower part (9) of the pushrod (7).

Abstract (de)

Eine Gelenkanordnung zur Betätigung einer Klappe oder Kuppel (1), die um eine ortsfeste, erste Drehachse (P 0 ) über einem ortsfesten Aufsatz (15) schwenkbar ist, weist ein lineares Antriebselement (7) auf, dessen eines Ende an einer schwenkbaren Verbindungsstelle (P 1 ) mit der Klappe in Verbindung steht und welches andererseits um eine erste Schwenkachse (P 2 ) schwenkbar an einem Stützhebel (10) angebracht ist. Der Stützhebel (10) ist um eine ortsfeste, zweite Schwenkachse (P 3 ) in einem Abstand zu der ersten Drehachse (P 0 ) schwenkbar. Ein zusätzlicher Umlenkhebel (11) greift mit einem ersten Ende schwenkbar an dem linearen Antriebselement (7) entfernt von der schwenkbaren Verbindungsstelle (P 1 ) an. Ein erstes Ende einer Zugfeder (14) steht mit dem Aufsatz (15) an einer Federanbringungsstelle (17) in fester Verbindung, die weiter von der ersten Drehachse (P 0 ) der Klappe entfernt ist als die erste Schwenkachse (P 2 ) des linearen Antriebselements (7). Um die Kräfte zu minimieren, welche die Klappe oder einen mit dieser verbundenen Lüfterrahmen verwinden, ist ein zweites Ende der Zugfeder (14) mit einem unteren Abschnitt (9) des linearen Antriebselements (7, 23) verbunden, der die erste Schwenkachse (P 2 ) einschließt.
