Abstract
A system for fixing and/or emergency opening of a leaf of a door, a window or other closure comprises a drive having at least one mechanical energy storage device, at least one electric motor having a motor shaft operatively connected to the leaf, and control electronics for controlling the electric motor. The electric motor can be actuated by the control electronics both for damping of the leaf movements and for fixing of the leaf against a force of the mechanical storage device and/or for electric motor-driven emergency opening of the leaf.
