Abstract

Serratura a cilindro con resistenza allo scassinamento migliorata, includente un corpo di serratura (5) e, al suo interno, un cilindro di serratura girevole (6) con un insieme di dischi di bloccaggio (7) e una sbarra di chiusura (8) formata sostanzialmente diritta la quale, nella sua posizione bloccata, è parzialmente collocata in una scanalatura (9) nella superficie interna del corpo di serratura (5) e parzialmente in una cava (10) nel cilindro di serratura (6) rispetto al corpo di serratura (5). La cava (10) nel cilindro di serratura (6) è munita di almeno una sporgenza (13) che si estende trasversalmente rispetto alla cava (10) ed è disposta preferibilmente nella sua estremità interna. La sbarra di chiusura (8) è rispettivamente munita di una scanalatura o di una corrispondente depressione (14) disposta in modo da cooperare con detta sporgenza (13) in maniera da impedire lo spostamento della sbarra di chiusura (8) nella direzione assiale fuori dalla cava (10) nel cilindro di serratura (6).Cylinder lock with improved burglar resistance, including a lock body (5) and, inside, a revolving lock cylinder (6) with a set of locking discs (7) and a locking bar (8) formed substantially straight which, in its locked position, is partially placed in a groove (9) in the internal surface of the lock body (5) and partially in a slot (10) in the lock cylinder (6) with respect to the lock body ( 5). The slot (10) in the lock cylinder (6) has at least one protrusion (13) which extends transversely with respect to the slot (10) and is preferably arranged in its internal end. The closing bar (8) is respectively provided with a groove or a corresponding depression (14) arranged so as to cooperate with said projection (13) so as to prevent the closing bar (8) from moving in the axial direction out of the slot (10) in the lock cylinder (6).
