Abstract

L'invention concerne un dispositif de porte à structure coaxiale comprenant une première porte rotative (1), une seconde une porte rotative (2) et premier élément d'entraînement (4) de porte rotative. La première porte rotative tourne autour d'un centre d'axe (S). La seconde porte rotative tourne de manière coaxiale à la première porte rotative. Le premier élément d'entraînement de porte rotative est relié à la première porte rotative, et transmet un couple de rotation pour tourner autour du centre de l'axe par rapport à la première porte rotative. La seconde porte rotative comprend un axe rotatif en forme d'anneau (23a) entourant un trou traversant qui comprend le centre de l'axe. Le premier élément d'entraînement de porte rotative est formé séparément de la première porte rotative, et est fixé à la première porte rotative en étant inséré dans le trou traversant de l'axe rotatif.
