High security lock cylinder
A cylinder lock 1 having a lock barrel, a cam 5, and a clutch mechanism for connecting the lock barrel 6 and the cam upon insertion of a key into the lock barrel. The clutch mechanism has a rotor 41 for transferring a rotation from the lock barrel to the cam. The lock has a security mechanism comprising a locking portion 9 configured such that the locking portion is rotatable between a first condition wherein the rotor is rotatable, and a second condition wherein the locking portion blocks the rotor from rotating. The cylinder lock is designed to automatically secure the cam if the lock is snapped by an attacker and the first lock housing is removed or disconnected from the cylinder lock. The security mechanism may include a biasing mechanism, e.g. a spring which rotates the locking portion 9 into the second condition. The locking portion 9 may have a bolt with bolt head (96 Fig 8/9) which enters a circumferential groove (48 Fig 4) in the rotor in the second condition preventing it from moving.
