When you open up a lock with a key do you
Quando apri una serratura con una chiave ti
ever stop to think about what's going on inside?
Fermi mai a pensare cosa sta succedendo dentro?
Only the correct key will open the lock.
Solo la chiave giusta aprirà la serratura
Why is that?
Perché è così?
Each key has its own unique shape.
Ogni chiave ha la sua forma unica.
These ridges on the key have to match
Queste rughe sulla chiave devono corrispondere
exactly with the lock for it to work.
esattamente con la serratura per farla funzionare.
There are many different types of locks,
Esistono molti tipi diversi di serrature,
but the most common one is called a Pin Tumbler Lock.
ma il più comune si chiama Pin Tumbler Lock.
Let me show you how this works.
Lascia che ti mostri come funziona.
This outside part is called the Case.
Questa parte esterna è chiamata Custodia.
The inside part is called the Plug;
La parte interna è chiamata spina;
this is the part that turns when the correct key is put in.
questa è la parte che gira quando viene inserita la chiave corretta.
The opening here, is called the Keyway.
L'apertura qui, si chiama Buco per la chiave.
On the inside, there's a few more parts.
All'interno, ci sono altre parti.
There are several vertical shafts that go through
Ci sono diversi "spilli" verticali che attraversano
the Case and the Plug.
La custodia e la spina.
Each shaft has a Spring, Driver Pin, and a Key Pin.
Ogni spillo ha una molla, un perno di guida e un perno chiave.
The springs press all the pins down
Le molle premono tutti i perni verso il basso
so that they all rest on this ledge.
in modo che poggino tutti su questa sporgenza.
You'll notice that the pins meet at a different level for each shaft.
Noterai che i perni si incontrano a un livello diverso per ogni spillo.
For the Plug to turn,
Per far girare la spina,
the pins must line up with the Shear line
i perni devono allinearsi con la linea di rotazione.
Now watch what happens when we insert the wrong key.
Ora guarda cosa succede quando inseriamo la chiave sbagliata.
The pins are not lined up,
I perni non sono allineati,
which means the the Plug won't rotate.
il che significa che la spina non ruoterà.
When we insert the correct key,
Quando inseriamo la chiave corretta,
everything lines up, and the Plug turns.
tutto si allinea e la spina gira.
So we've covered the case of one key for one lock;
Quindi abbiamo assicurato la custodia di una chiave per una serratura;
there's another case.
c'è un altro caso.
Let's say there's a building,
Diciamo che c'è un edificio,
where there's a different key for each door,
dove c'è una chiave diversa per ogni porta,
but there's also a key that opens
ma c'è anche una chiave che apre
every single door in the building.
ogni singola porta nell'edificio.
This is called a Master key.
Questa si chiama chiave maestra.
For the Master key to work, there must be an extra pin
Perché la chiave master funzioni, è necessario un perno aggiuntivo
in at least one of the Vertical Shafts.
in almeno uno degli spilli verticali.
We call this the Master pin.
Lo chiamiamo il perno principale.
Now the Plug will turn if there is a key that
Ora la spina girerà se una chiave
raises the pins either to here or to here.
solleva i perni qui o qui.
So here's our regular key going in;
Quindi ecco la nostra chiave regolare in corso;
Now here's the Master key going in.
Ora ecco la chiave maestra in corso.
Both keys allow us to turn the Plug.
Entrambe le chiavi ci consentono di girare la spina.
Some master key systems will have
Alcuni sistemi "chiave maestra" avranno
more than one Shaft with a Master pin.
più di un albero con un perno master.
So that's the basics of how a Pin Tumbler Lock works.
Ecco quindi le basi di come funziona un Pin Tumbler Lock.
There's a whole lot going on
C'è molto da fare
every time you use a key to open a lock.
ogni volta che usi una chiave per aprire un lucchetto.

I go through and show all the little pieces inside
Entro nei marchingegni e mostro tutti i piccoli pezzi all'interno
and how they work together.
e come lavorano insieme.
I'll go ahead and put a link for it right here.
Vado avanti e inserisco un link proprio qui.
