ABSTRACT:
A bar lock system includes first and second plates. Each plate includes lugs for mating with an adjacent plate. The first plate includes an inner wall defining an axial bore having opposite forward and rearward openings and the second plate includes an inner wall defining a bolt-receiving cup. The stop member extends a predetermined distance into the axial bore to provide a rearwardly presented blocking surface. A key-actuated bar lock mechanism is position within the axial bore of the first plate for sliding movement therein toward a second plate-locking position. The bar lock mechanism includes a bolt for entering the bolt-receiving cup upon movement of the bar lock mechanism to its second plate-locking position. The mechanism further includes a retainer assembly for selectively confining the stop member to limit sliding axial movement of the bar lock mechanism relative to the first plate in forward and rearward directions so that unauthorized removal of the bar lock mechanism from the axial bore is prevented. The lugs, bolt assembly, and retainer assembly cooperate to interlock the first and second plates, thereby preventing unauthorized separation thereof.
