The secuirty door with an automatic mechanical locking system
Meccanya is a security door with an automatic locking system that lock the door every time you close it. It's an innovative door because it works as a door with the electronic locking system, but it has a mechanical one.
Meccanya protects the house anytime, either when you are at home and when you are away. You don't need to lock the door with the key, because it does it automatically when you shut it.
The functioning is very simple:
When you shut the door, both the latchbolt and the lateral deadbolts get closed at the same time.
To open the door from the outside, you have to unlock the locking system by turning the key twice, like the traditional locking systems, and you turn the knob.
To open the door from the inside, you simply have to turn the handle.
