Abstract: An improvement of locking mechanisms having four latching bolts of the type that include a partially teethed disk mounted to a case and being cooperatively meshed with a geared cylinder that actuates it. The improvement comprises a step of bending of the linkage member that, through a rod, transmits the axial movement to the latching bolts. The axial movement is forced on the rod members by making coupling outer pins connected to the rod members to travel along radially disposed slots on the cover of the locking mechanism. The step in the linkage members allows linkage members to converge over the opposite ends of adjacent linkage members when the disk is rotated to the position that causes the former to be in the innermost position. This combination of elements allows the most volumetric efficient utilization of the space available by maximizing the axial travel of outer guiding pin member and, consequently, the latching bolts driven by it.
