Patent

CA 2434572

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.

La présente invention concerne un entraînement électromécanique de battant articulé comprenant un dispositif de fermeture de porte (1) doté d'un pignon (6) disposé de manière excentrique, présentant un cercle primitif circulaire, et s'engrenant avec une crémaillère (5) disposée contre le piston (4). Selon l'invention, une configuration particulière du cercle primitif et des dents (9) de la crémaillère (5) est obtenue par adaptation à la denture du pignon (6). Afin d'obtenir un mouvement optimal du piston (4) dans le boîtier (2) du dispositif de fermeture de porte (1), l'invention prévoit une configuration améliorée du temps de fermeture.
