Abstract (en)
The present invention relates to a lock of the cylinder type, actuatable with a flat key, with antiburglar features. The cylinder lock comprises a plug (2) and auxiliary pins (9) which are disposed in seats (5), provided on the plugs (2) and arranged laterally to the channel (3) of introduction of the key. On introducing the key into the lock the pins (9) are displaced from their seats (5) such that, when the key is not the right one, they will engage into recesses (7) on the outer casing (1) of the lock, thus inhibiting rotation of the plug (2). By intervening on the pins it is also possible to obtain a set of hierarchically different locks for fabricating master key systems.
