OPERATING PRINCIPLE OF THE SECRET PART OF THE CYLYNDER MECHANISM.
Coding in the given mechanism is based on the physical principle of interaction of the magnetically soft (perceiving a magnetic field) elements with dot constant magnets.
The description of the operating principle of the mechanism uses the following conditional terms for its parts:
Fig. 1
Blocking element (Áëîêèðóþùèé ýëåìåíò) – a ball from magnetic steel.
Key (Êëþ÷) – a body with a steering constant dot magnet.
Piston (Ïîðøåíü) – a moving part, which can control the locking device when interacting with it.
Code element (Êîäîâûé ýëåìåíò) – a cavity (aperture) in which the blocking element cease to block the piston’s movement.
Case (Êîðïóñ) – the part containing the piston, the blocking element and the cavity of the code element.
Locking device (Çàïèðàþùåå óñòðîéñòâî) – an actuating mechanism of the lock.
Operation of an individual chamber.
Let us see interaction of the piston with the blocking element freely laying in the bottom part of the cavity in the case, between a wall of the piston and a wall of the case (Fig.1). When pressure is applied to the piston toward the wall, an obstacle appears in the form of the blocking element, which does not allow the piston to move to the wall of the case at a distance smaller, than its own size (in this case – the diameter of the ball).
In the given position the piston does not interact with the locking device.
Fig. 2
When a key with a dot magnet is pressed against the external side of the piston, the ball, being attracted to the magnet through the wall of the piston, rises upwards and takes position opposite to the axis of the magnet. If the magnet in the key is in position opposite to the cavity of the code element, the ball accordingly will take position opposite to the cavity of the code element. In this case the piston can move forward up to a contact with the wall of the case and interact with the locking device.
Fig. 3
In this position the key controls the locking device (for example, twirls it).
It should be pointed out, that the cavity of the code element can be in any place on the wall of the case and its position cannot be determined visually or by other methods, because the piston, the case and the blocking element do not contain magnets, electronic and other components, which can be determined at a distance .
Fig. 4
In a real mechanism it is mechanically possible to have up to 7 such individual chambers, like the one we have discussed above. In this case there can be up to 7 dot magnets in a key and accordingly there should be up to 7 cavities of the code elements in the case.
Now, in order to make the piston move to the position of interaction with the locking device, it is necessary to lift by means of the dot magnets already up to 7 blocking elements.
At that, each blocking element should move to a dot magnet from an equilibrium position under action of the gravity force (from a position below). Each blocking element will move in its own, different from other, direction. If all the blocking elements take position opposite to the cavities of the code elements, the piston can contact the locking device, interact with it and implement locking or unlocking.
Even if just one blocking element does not rise opposite to its cavity of the code element, the movement of the piston will not be possible and there will be no interaction with the locking device.
Fig.5
Since there are many places for arrangement of the cavities of the code elements (ends of arrows) and they are situated statistically equiprobably everywhere, theoretically and the more so, practically it is not possible to determine their positions in each concrete case.
The blocking elements should take their positions opposite to the cavities of the code elements simultaneously. It is impossible to set them in turn, which excludes the use of a master key and opening without the original key.
