<p>LAZLO BAKO COMBINATION LOCK A combination lock in which an actuator is movable in a predetermined direction from a rest position to an unlocking position to unlock the lock and is further movable in the predetermined direction beyond the unlocking position to a combination-changing position to permit the combination to be changed. Movement of the actuator to the unlocking position can only occur when combination dials and sleeves coupled thereto are "on-combination". In the combination-changing position of the actuator, the sleeves are uncoupled from the dials. A stop mechanism is normally effective to prevent movement of the actuator to the combination-changing position and is rendered ineffective by depressing a plunger. The same stop mechanism holds the actuator at the combination-changing position during changing of the combination. (1)</p> |
