Abstract

Un appareil de ventilation de bâtiment comprend un cadre (1), une plaque d'obturation (2), et un verrou de sécurité contre l'incendie (100). Le verrou de sécurité incendie (100) comprend un corps principal (10) monté sur le cadre (1), un siège coulissant (20), un élément de commande fusible (30), une unité de verrouillage (40), et des premier et second éléments élastiques (50, 60). L'unité de verrouillage (40) est mobile entre une position de verrouillage, pour verrouiller la plaque d'obturation (2) contre le cadre (1), et une position de déverrouillage pour déverrouiller la plaque d'obturation (2). Lorsque l'élément de commande fusible (30) n'est pas fondu, le second élément élastique (60) est préchargé par l'élément de commande fusible (30) pour stocker une force de rappel. Lorsque l'élément de commande fusible (30) est fondu, la force de rappel du second élément élastique (60) entraîne le siège coulissant (20) pour déplacer l'unité de verrouillage (40) vers la position de déverrouillage.
