Abstract

Selbsttätig schließende Brandschutzeinrichtung (10, 10'), insbesondere zur Abschottung eines Kanals (7) in einem Lüftungs- und/oder Klimatisierungssystem, als oder mit mindestens ein(em) schwenkbar angeordnete(s/n) Absperrelement (1, 1'), welches bei Hitzeeinwirkung nach Freigabe aus einer durch einen Schmelzlotkörper (3, 3') gebildeten Arretierung in einer zur Durchtrittsrichtung (9) im wesentlichen parallelen Offenstellung in eine im wesentlichen quer zur Kanalachse gerichteten Geschlossenstellung schwenkbar ist, wobei das Absperrelement ein in Offenstellung vorgespanntes Federelement (2, 2') oder ein mittels einer Feder vorgespanntes scharnierartiges Verbindungselement aufweist, welche(s) mit einer Kröpfung oder einer entsprechende Ausnehmung zur Aufnahme des Schmelzlotkörpers versehen ist, in welche der Schmelzlotkörper (3, 3' 3") derart eingebracht ist, daß das Federelement oder das scharnierartige Verbindungselement in seiner vorgespannten Stellung blockiert ist, solange der Schmelzlotkörper nicht geschmolzen ist.

Automatically closing fire protection device (10, 10 '), in particular for sealing off a duct (7) in a ventilation and / or air conditioning system, as or with at least one pivoting shut-off element (1, 1'), which can be pivoted when exposed to heat after release from a lock formed by a fusible link (3, 3 ') in an open position essentially parallel to the direction of passage (9) into a closed position essentially transverse to the channel axis, the shut-off element being a spring element biased in the open position ( 2, 2 ') or a spring-loaded hinge-like connecting element, which (s) is provided with a crank or a corresponding recess for receiving the fusible body, into which the fusible body (3, 3' 3 ") is introduced such that the spring element or the hinge-like connecting element is blocked in its prestressed position as long as the solder body has not melted.
