Abstract
A braking device for a movable door leaf according to the invention comprises at least one generator, at the output terminals of which, a generator voltage can be generated, by means of which a charging circuit for supplying an open-loop and/or closed-loop control unit may be charged, by means of which an electric braking device, such as, in particular, a braking motor or the like, is controllable, which generates an effective braking force for damping the movement of the door leafs. Therein, the generator shaft of the generator is rotatable for generating the generator voltage with the discharging of a mechanical generator energy storage specifically associated with the generator, which is charged by a respective opening or closing movement of the door, and, during a respective closing or opening movement of the door, is mechanically decoupled from the same or its axis of rotation, and discharges in the state mechanically decoupled from the door leaf or its axis of rotation. Further specified is a door closer, having a rotatable door closer axis, coupleable with a door leaf, cooperating with a mechanical door closer energy storage device, and a correspondingly designed braking device.
