How the Hidden Mechanical Locking Mechanism Works
The hand-crafted custom bookcase requires you pull open each of the visible drawers, before a hidden control springs out and allows you to trigger the secret compartment built into what looks like a normal molding.
To make things more complex, each of the drawers must be pulled out to a certain point before the latches they control slide out of the way, similar to how the pins in a regular lock work. That finally allows a length of wooden dowel to slide out – hidden, normally, as a knot in the wood itself – and when you twist it and then push it back in, a cable tracked around the back of the cabinet allows the hidden drawer to spring out.
