发明名称 Electrically driven entryway actuation system
摘要 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.
