Security lock for reinforced doors - has key and probe lock closures enabling and disabling bolts and preventing forcing

摘要

The access to the probe system is by way of an exterior ball or dome that is camouflaged, and uses a displaceable piece which is connected to another interior ball or dome. This gives access to the inside by working a lever or similar arrangement in such a way as to work the probe system, using the probe and then the key, or the key and then the probe. The system has two locks, one lock working the usual blocking system, while the other lock works the security probe system by moving plates laterally closing both sides of the door.
