<p>Flat key (1) and/or a lock-up pin-tumbler (4) having a cylindrical core (3), that is rotatably mounted within a cylindrical body and that is provided with hold-downs (6), supports a stop (7), defining depth of the flat key (1) insertion into a guide (2) thereof in the cylindrical core (3). This stop (7) consists of a projection (8) performed on the flat key (1) in the direction of insertion thereof , or a recess and a recess (9) or a projection arranged on the cylindrical core (3) front side. Stop area defining the depth of the flat key (1) insertion is adapted either on the projection (8) provided the length thereof is greater than the recess (9) depth or outside the projection (8) optionally a recess, when the projection (8) can be inserted into the recess (9) without coming in contact therewith. The projection can be performed as an oblique tooth.</p> |
