摘要： A cylinder type lock having shield means encircling the tumblers therein is disclosed. The shield means is provided as a split line structure like the lock tumblers but can have a lifting or displacement travel thereof for moving the split line thereof to the lock shear line which is different than that required for an associated tumbler. Employment of shield means in association with a tumbler makes the lock more difficult to pick.
