Patent ID: 10808445

Abstract:
The invention relates to a braking device (20) for a moving door leaf (5) comprising a generator (22), the at least one generator shaft (24) of which can be rotated via a movement of the door leaf (5), and at the connection terminals of which a movement-dependent first output voltage occurs, which is applied to an evaluation and control electronics system (10) having an evaluation and control unit and a braking circuit. The braking circuit generates an effective braking force for damping the movement of the door leaf (5), wherein the braking circuit (18) has at least one switch element, via which the connection terminals can be short-circuited, as well as a door closer (1) having a braking device of this type. According to the invention, a second output voltage of the generator (22) is applied to a charging circuit (12), which stores electrical energy for supplying the evaluation and control electronics system (10) with power.
