<p>The new lock system includes the following: one cylinder (1) with six key rows (12-13-14), all of them loaded; a key (4) with six treads (6) and a removable stop (8) which may be selectively placed on the bottom opening (17) located at the end of the key (4) insertion channel (15), and the location of the stop (8) is such that it allows for the movement of a step or range between two successive rows (12-13-14); when the removable stop (8) is installed, it gives a penetration limit for the key (4) so that the five key rows (12-13-14) closest to the front (16) of the "tube" (3) act with the five treads (6) closest to the end (7) of the key, while the sixth key row (12-13-14) operates in relation to the end (7) of the key (4) itself.</p> |
