The invention relates to an automatic door or window system, comprising two wings (1, 2) driven in opposite direction and two fixed lateral wings (1a, 2a). In order to achieve a compact structure, each wing (1, 2) is fitted with a separate drive motor (10) whose driven member acts directly on the rollers (6a) of the roller wagon of the wings. The drive motor (10) is accommodated in the area of the roller wagon in the running rail (3) and is displaced along with the wing (1, 2). |
