Abstract

A time lock, for example for high security locks of safes or strong rooms, comprises at least one spring-driven timing device coupled to a first regulator (35) via a wheel-train (34). One of the wheels (39) of this wheel-train is equipped with a differential mechanism which forms switching means enabling the wheel-train to be coupled to a second regulator (50) comprising a flanged disk (55). Hence, by controlling the switching means, the speed of running of the timing device may be set so as to be able to abruptly free the residual energy of the spring (22a) when the fixed time setting has elapsed. This provides a better determination of the precise instant when the lock is unlocked.
