Wooden combination lock

It turns out, combination locks can be made not only of iron, but also of wood . It is unlikely that it can be used in practice, but simple design looks very elegant. A good project to pomasterit weekend. In addition, the model clearly shows how to actually operate combination locks (after all, they even interested in Richard Feynman himself ). < br />
By the way, no one bothers to make all parts of the rail in the same way - get a real combination lock that can be used in!



The author has set a goal to make the code lock design as simple as possible and it seems that has been successful: there are 11 parts.



This castle does not look ugly, quite the contrary.

In contrast to these locks, the main purpose was not the efficient operation and visualization to show the mechanism in action. Therefore, the case is made public, all interiors are clearly visible.

As in a real castle, the mechanism consists of three rotors or castors. Each has a notch. When three notches line up, the bolt is lowered into the groove to learn a triple - and the lock opens.



The front rotor is directly connected to the disk set of numbers, and the rest of the movement is transmitted through a kind of ears. For the first digit corresponds to the far wheel.



Then the rotation is in the opposite direction until the wheel becomes secondary in his place. Eventually, the rotor rotates only forward.



Turn can be both right and left-to-right and left-right-left. Incidentally, this also applies to conventional mechanical combination locks.

Unfortunately, detailed drawings of wooden models are in the paid access. But pictures and videos can be fairly accurately restore sizes. The design is really very simple. If you play with a bit of the wood, we get something that is very close to the original. Alternatively, it is possible to estimate in advance the type of CAD AutoCAD, as did the author himself.

Naturally, the castle scale: makes the model of all sizes, some like it.
