ELECTROMECHANICAL HINGED WING DRIVE

摘要

The invention relates to an electromechanical hinged wing drive comprising a door closer (1) with an eccentric pinion (6) that has a circular pitch circle and that intermeshes with a toothed rack (5) that is mounted on the piston (4). The invention is further characterized in that the pitch circle and the teeth (9) of the toothed rack (5) are adapted to the teeth of the pinion (6). In order to obtain an optimum displacement of the piston (4) in the housing (2) of the door closer (1) the design of the closing delay is improved.
