In a safe locking mechanism including a spindle which rotates a cam plate to extend or withdraw a plurality of locking bolts, a novel relock mechanism includes a floating hard plate interposed between the inside surface of the safe door and the cam plate. A plurality of springs are disposed between the interior surface of the safe door and the floating hard plate to bias the hard plate toward the cam plate. Each of the locking bolts includes a chordal notch therein to engage the edge of the hard plate and prevent retraction of the locking bolts. The cam plate includes raised camming rails which engage raised buttons on the hard plate, so that rotation of the camming plate releases the hard plate from the notches in the locking bolts and permits the bolts to be withdrawn only by rotation of the spindle.

In a safe locking mechanism which includes a plurality of retractable locking bolts extending from a safe door, said locking bolts being generally disposed in a common plane, a relock mechansim comprising a first plate disposed in the safe door and extending to said locking bolts, means on said locking bolts for releasably engaging peripheral edge portions of said first plate with said locking bolts in the extended position to block retraction of said locking bolts, means for urging said first plate toward said common plane to engage said means on said locking bolts, and means for disengaging said first plate from said locking bolts to permit retraction of said locking bolts by said locking mechanism.
