Abstract

Lock cylinder, especially profile cylinder, with pin tumblers or tumblers, spring loaded, arranged in a double row and offset from each other in the cylinder core and in the cylinder housing, running on both sides of the longitudinal central plane of these and parallel to them, as well as transversally the axis of the lock cylinder, with a key channel disposed in the cylinder core, which runs in the longitudinal direction thereof, and with a key to be introduced there, in which two seatpost halves are provided, located next to each other corresponding to the two rows of core pins, each of whose halves has on the narrow side a row of key notches carved in a different manner, characterized in that. The core plug holes have in each case two drill sections of different magnitude of diameter, of which the larger diameter drill sections are oriented towards the existing pin holes in the housing and therefore coincide as regards the diameter, and in that the core pins, capable of freely rotating inside the core pin holes, are provided at their ends spaced from the key channel with thickened guide heads, with which those are guided in the bore section of the key. Greater diameter in common with the housing pins, which in the present case have a front surface in the shape of a truncated cone or spherical, and because the seatpost halves provided in the key are arranged with their corresponding rows of notches, without reciprocal distance immediately next to each other.
