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.</p> |
