Abstract: A safe or other secure containment having a body, a door for entry into the body, a moveable latch system effective for latching and unlatching the door to the body, a lock attached to the door for locking the safe is made more secure by an active hardplate and an independent lockout means effective for preventing the unlatching of the safe door upon the displacement of the active hardplate caused by an unauthorized and unlawful attempted entry into the safe. Existing safes also can be modified.

Abstract: A door condition sensor for a safe having a door. The sensor has a housing mounted on an inside surface of the door, frame engageable means for abutting the door frame, a driver rotatably mounted in the housing, analog signal generator mounted in the housing having a rotatable part driven by the driver, and spring for extending the frame engageable means that is slideably mounted and confined to linear displacement in the housing. The driver transforms displacement of the frame engageable means into rotational orientation of the driver. The generator produces analog signals corresponding to the rotational orientation of the rotatable part. A means converts analog signals from the generator to corresponding digital signals that are proportional to displacement of the frame engageable means. Memory means compares the displacement with a set point range thereby continually monitoring the condition of the door.

Abstract: A lock for safes and other security devices is disclosed having a case mountable on the inside of a safe door. A locking bolt in a slidable relationship within an opening in the case, moves between locked and unlocked positions. A gate, constrained in slidable relationship by and with the locking bolt, normally prevents the locking bolt from moving out of the locked position. An internal case extension obstructs the gate, when the lock is not activated, preventing the locking bolt from moving towards the unlocked position. A camming member, pivotally attached to the locking bolt, repositions the gate allowing the locking bolt to move out of the locked position. A solenoid driven armature, linked to the camming member and connected to the locking bolt, pivots the camming member and moves the locking bolt to the unlocked position. The locking bolt is held in the locked position when not activated by a spring.
