Abstract
A high security padlock for use with a pair of companion locking bars having apertured hasp end portions to be disposed in alined abutment and locked together, the padlock comprising a padlock body having a rearwardly opening cavity to receive the alined abutting hasp end portions therein and the padlock including a shackle extending through said cavity to pass through a pair of alined apertures in the hasp end portions, and a lock mechanism with the padlock body, together with a wedge attack resisting collar member shaped to surround three sides of the pair of alined hasp end portions having a portion disposed in the rearwardly opening cavity of the lock body and portions protruding rearwardly beyond the rear surface of the lock body. The collar member has a knuckle formation received in a socket in the lock body for pivotally locating the collar for swinging movement about a vertical pivot axis, and the collar member has surface portions coacting with confronting surface portions of the cavity to tightly grip the opposite lateral surfaces of the pair of hasp end portions within the cavity when an attack wedge-like tool is driven against the rear of the lock body into engagement with rearwardly projecting end portions of the collar member.
