A lock mechanism has at least one tumbler pin having one or more slots in the tip surface of the pin and a key blade which is formed with a projection extending from the surface of the bitting area. The tumbler pin can be rotatable in such a manner that it will seek to accommodate the projection on the surface of the key and to match the surfaces of the key and tumbler pin tip, thus aligning the tumbler pin at a position predetermined by the key bitting. In this regard, the tumbler pin tip is preferably tapered and adapted to engage with a key having a complementarily shaped bitting surface, i.e., complementary to the tapered surface of the tumbler pin tip, such that the tumbler pin will seek to accommodate the tapered surface of the key bitting to align the tumbler pin at a proper position. Alternatively, the tumbler pin can include a projection or the like to inhibit rotation of the tumbler pin. Cylinders and keys according to the present invention can be arranged in hierarchical systems to perform special functions and provide master keying capability.

Serrure à gorge(s) dont l'extrémité de la gorge présente une ou plusieurs rainures, avec clé à tige dont le panneton présente une saillie. La gorge est entraînée en rotation de manière à s'adapter à la saillie et aux encoches du panneton, ce qui la place dans la position déterminée par la forme du panneton. De préférence, l'extrémité de la gorge est de forme tronconique et complémentaire de celle du panneton, pour que puisse s'effectuer l'accouplement et l'entraînement de la gorge dans la position déterminée. Dans une variante, la gorge peut présenter une saillie ou autre organe servant à la bloquer dans la position déterminée. Les serrures et clés de la présente invention peuvent être adaptées pour créer un système hiérarchisé de dispositifs d'ouverture, avec clés individuelles, passe-partout partiels et passe-partout général.
