<p>PCT No. PCT/CH91/00010 Sec. 371 Date Sep. 17, 1991 Sec. 102(e) Date Sep. 17, 1991 PCT Filed Jan. 11, 1991 PCT Pub. No. WO91/10795 PCT Pub. Date Jul. 25, 1991.A lock system has lock cylinders (5) in which the rotor (9) is lodged as usual in the cylinder housing, (11) as well as lock cylinders (6) in which the rotor (10) is rotated through 180 DEG about its longitudinal axis relative to the other rotors (9). The security keys for the lock system are flat keys and not turning keys and, in the event that these are priority keys, have two completely independent key codes. The invention also provides a further possibility for increasing the number of variations of the lock and thus for increasing its security.</p> |
