<p>Two-part spring-loaded pin tumblers, in radial holes, are set for movement by a flat key positioning them with the aid of cutouts in its sides, in a row of rotary cylinder locks. The system enables an increase in the number of different closure possibilities. One of the cutouts, at least, in individual keys, has two or more different control faces for the head of the relevant tumbler pin. Heads of appropriate pins, in individual locks, are arranged so that pins can be located in the correct sliding setting only when heads act in conjunction with one control face, or several simultaneously.</p> |
