PICK PROOF LOCKING PLATE FOR PADLOCK |
摘要 |
A cylinder assembly located in the chamber of a padlock has a key actuated rotating cylinder plug to which is attached a locking plate. Locking lugs at opposite ends of the locking plate engage notches in the long and short legs of a shackle to hold the shackle in locked position. Engagement of the lugs with the notches is such that when the lug engaging the short leg is clear, the lug engaging the long leg is still partly engaged. For that reason the shackle cannot be unlocked by unauthorized manipulation of a shim inserted through the clearance around the short leg of the shackle to release the locking lug from engagement with the short leg.
