Abstract (en)
[origin: EP2239016A1] The present invention relates to a device (3) for rotating a damper blade (2) of a fire damper (1) about a damper blade axle (A), in which the damper blade (2), within a specific angle range, cannot be rotated with respect to its open and its closed position as a result of a force acting on the damper blade (2), comprising a first transmission arm of the damper blade (4) on the damper blade axle (A) and a second, drivable transmission arm (5) on a drivable axle (B), which are hingedly connected by a coupling element which is arranged on the first transmission arm of the damper blade (4) such that it can be displaced, and is arranged on the second, drivable transmission arm (5) such that it can be displaced and which is guided according to a flowing curve in such a manner that, in the open and in the closed position, the first transmission arm of the damper blade (4) is positioned according to the tangent line of this curve.
