Abstract

A lock for a door or the like has a deadbolt assembly which comprises a bolt (15) and a drive mechanism in the form of a bolt thrower (20) which is adapted to be operated by a key. A lever (18) is arranged between a surface (16a) of the bolt (15). The bolt thrower (20) is arranged to move the bolt (15) between bolted and unbolted positions by engaging in a recess (15d) when said bolt thrower is rotated. The lever (18) is so configured that, when the bolt thrower is operated to move the bolt from the unbolted to the bolted position, the lever is effective to increase the throw of the bolt by at least 3mm. The lock is applicable to both multi-detainer mortice locks and cylinder operated locks. <IMAGE>
