An electrically driven entryway activation system for opening and closing two spaced swinging doors hung on spaced rotating parallel door posts comprises a base plate extending between the door posts. Levers attached to each door post rotate in a plane parallel to the base plate. A low profile actuation system spaced between the levers comprises a center post, a sector gear journaled on the center post for rotation parallel to the base plate, and a low profile gearmotor mounted between the base plate and the sector gear. A low profile emergency manual mechanism is provided for unclutching the output pinion gear of the gearmotor.

L'invention concerne un système d'actionnement d'entrée commandé électriquement, qui sert à ouvrir et à fermer deux portes battantes espacées, suspendues sur des montants de porte parallèles tournants espacés, ledit système comprenant une plaque de base se déployant entre les deux montants de la porte. Des leviers fixés à chaque montant de porte tournent dans un plan parallèle à la plaque de base. Un système d'actionnement peu encombrant, espacé entre les leviers, comprend une tige centrale, un secteur denté pivotant sur la tige centrale de manière à tourner parallèlement à la plaque de base, et un moteur à engrenages peu encombrant, monté entre la plaque de base et le secteur denté. Un mécanisme manuel d'urgence peu encombrant permet de désaccoupler l'engrenage à pignons de sortie du moteur à engrenages.
