<p>Profile system for forming cross-sections of flat keys (7) for lock cylinders, especially in locking systems is rendered with in principle flat and approximately parallel sides of the key, with key back and with opposite and on the front plate manufactured key teeth, for positioning retainer pins divided to core pins and body pins, which are in corresponding ribs for a cylindrical cores key flexibly burdened in the key back direction. Grooves (2, 3) are cut in flat sides of the flat keys (7) optionally ribs cut in the key channel, are adapted as variation profile elements and guiding profile elements and from at least one groove (2, 3) in the flat key (7) or rib in the channel for the key jets out branching groove (4, 8) or branching rib, of which the direction of cutting-in is different from the direction of cutting-in of the groove (2, 3) or the rib.; A branching groove (4, 8) is set at a certain distance from the guiding groove (2, 3) bottom in the flat key (7), or the branching rib is set at a certain distance from the guiding rib. In the flat key (7), another groove jets out from at least one groove (2, 3) among the grooves (2, 3), which are in opposite direction and are overlapping, in the central cut of the key (7) tooth, as the branching groove (4, 8) at a certain distance from the groove (2, 3) bottom. The directions of groove (2, 3) and branching groove (4, 8) cutting-in are different and they deviate for example by 60 degrees.</p> |
