ABSTRACT:
A safe door locking system comprising a pinion rotatably mounted inside the door, and a door operating handle wheel at the outside of the door which is drivingly coupled to the pinion. A rack bar is coupled, via a gear mesh to the pinion. The door is adapted to lock by a plurality of in-unison rotatable disc-like lock bolts coupled to the rack bar. The rack is of hybrid structure, constituted by a double-T profiled, non-ferrous metal extruded bar. Inside one of its elongated cavities, at appropriate intervals as determined by the location of the said lock bolts, there are fastened a respective number of gear-toothed inserts meshed with the said lock bolts. An additional gear-toothed insert is fastened inside the other of the elongated cavities, meshing with the pinion. The pinion, the inserts, and the disc lock bolts are all made by slicing off extruded non-ferrous metal bars of suitable shapes, as the case may be.
