ABSTRACT:
A safe door assembly comprising a door casing, a door, a plurality of locking bolts operated by a combination lock so as to be selectively extended outwardly from or retracted inwardly into said door to lock or unlock, respectively, the door to the casing; the casing including a seat to accomodate a shoulder on a door and a recess to receive each of the outwardly extending locking bolts, the door having a combination lock with a retractable tongue directly connected to one locking bolt and also connected via a sliding link bar and lever means to the remaining locking bolts in such a fashion that all bolts extend and retract simultaneously; a pivotable relocking bar spring biased to pivot into a position which prevents movement of the sliding link bar and thereby prevents retraction of the locking bolts when the combination lock is displaced inwardly from its normal position; the assembly also comprising a hardened steel barrier protecting the outer extremities of said locking bolts from access by a drill, a hook means of attachment of one locking bolt to the tongue of the combination lock, and weakened handle support bolts which will shear in the shank portion when subjected to the normal torque or unloosening the bolt from its lock nut. The safe door assembly of this invention provides an improved protection against unauthorized tampering.
