Abstract (en)
[origin: WO0039421A1] The security cylinder lock is characterized by the existence of a system of interlocking circumferential grooves (21) and ridges (5) affecting both cylinder shell (4) and the rotatable plug (6), and by a cylindrical key (10) with a plurality of "V"-shaped skew cut bits (12). Given that each spring-biased (3) tumbler pin (1) and driver (2) pair is placed inside radially-oriented holes (11) intersecting the circumferential grooves (21) and ridges (5), the ability of the rotatable plug to rotate within the outer shell, depends upon the angular and elevational positioning of each tumbler pin/driver pair, which, upon the insertion of the properly bitted key, assumes a positioning that allows their interlocking contact surfaces (15, 19) to align themselves with the circumferential grooves (21) and ridges (5) in each location that a tumbler pin hole (11) intersects a groove and a ridge.
