<p>A lock is disclosed which has a bolt which can adopt a latching position and an unlatching position. Means are provided for moving the bolt from the latching position to the unlatching position. The lock also includes one or more locking components which can adopt a locking position in which the bolt is prevented from moving from the latching position to the unlatching position, and an unlocking position in which the locking component(s) do(es) not prevent the bolt from moving from the latching position to the unlatching position. A lock cylinder is provided which has a cylinder cam that can adopt an unlocking position and a deadlocking position. And there is also a deadlocking component which can adopt a disengaging position in which the deadlocking component does not prevent the locking component(s) from moving from its/their locking position to its/their unlocking position; and when the locking component(s) is/are in its/their locking position, an engaging position in which the deadlocking component prevents the locking component(s) from moving from its/their locking position to its/their unlocking position. The cylinder cam is functionally linked to the locking component(s) and the deadlocking component such that: when the cylinder cam is in its unlocking position, the locking component(s) is/are in its/their unlocking position and a deadlocking component is in its disengaging position; when the cylinder cam is in its deadlocking position, the locking component(s) is/are in its/their locking position and the deadlocking component is in its engaging position.</p> |
