<p>A member, for example a bolt of a bolting mechanism, has a direction of translation. A plurality of blades are arranged to slide progressively across an arrest of the member, in a direction transverse to the simultaneous movement of the member in the direction of translation, to thereby prevent reverse movement of the member over a continuous range of member positions. In particular, each blade prevents return movement over a different range of member positions than the other blades.</p> |
