Multiple-opening e.g. door, securing system for use in building, has bolts and strikes that are adapted so that bolts penetrate into strikes situated at immediate proximity to rotation axes with respect to frame

The system has a control unit (18, 18) movable between an opening position and a closing position. A set of bolts (4-9, 4-9) and a set of strikes (13-17, 13-17) are provided, where the bolts (4, 5, 8, 4, 5, 8) and the strikes (13, 14, 17, 13, 14, 17) are adapted so that the bolts penetrate into the strikes. The strikes are situated at immediate proximity to rotation axes (A-A, A-A) with respect to a frame (12). An independent claim is also included for a method of securing an opening rotatably mounted around an axis of rotation of the opening. Système de fermeture multipoints (1) pour ouvrant(s) (2, 2') comportant :- au moins un ouvrant (2, 2') monté pivotant autour d'un axe de rotation (A- A, A'-A') par rapport à un dormant (12) ;- plusieurs pênes (4-9, 4'-9') mobiles entre une position de sortie du pêne (4-9, 4'-9') dans laquelle une portion du pêne (4-8, 4'-8') pénètre dans une gâche correspondante (13-17, 13'- 17') et une position rentrée du pêne (4-8, 4'-8') dans laquelle le pêne (4-8, 4'-8') est dégagé de sa gâche (13-17,13'-17');- un moyen de commande (18, 18') relié mécaniquement aux pênes (4-9, 4'-9').Parmi lesdits pênes (4-8, 4'-8') et gâches (13-17, 13'-17'), certains pênes (4, 5, 8, 4', 5', 8') et certaines gâches (13, 14, 17, 13', 14', 17') sont situés à proximité immédiate de l'axe de rotation (A-A, A'-A') de l'ouvrant considéré (2, 2') par rapport au dormant (12).
