<p>An interlocking dead bolt lock and strike assembly having a lock housing enclosing a rotatable actuator for a lock bolt reciprocable between a retracted and a dead-locked position, an idler cooperating with the actuator for a key-operated lock actuation, and an extension on the housing acting to enclose the strike and cover the lock bolt in its projected dead-locked position. The housing may also include a reciprocable flag indicating when the bolt is projected, and an interior tumbler lock mounted on the housing which, when turned to one position allows the bolt to be operated by an exterior tumbler lock, and when rotated to a position 180 DEG therefrom, prevents the exterior tumbler lock from operating the lock bolt.</p> |
