Abstract
A high-security shackleless lock is provided. The lock includes a shackle pin adapted to move between a closed position extending across a lock body recess to engage a staple; and an open, staple-free position. A lock bar mounted entirely within the lock body can be move between a closed shackle pin engaging position to retain the shackle pin in its staple-engaging position, and an open shackle pin-free position wherein the shackle pin does not extend across the lock body and cannot engage a staple. A shackle pin spring urges the shackle into its open position, and a lock bar spring urges the lock bar into its closed position. The shackle pin has a distal end formed with a head element of extended dimensions. The lock body defines a recess adapted to closely confront the shackle pin head when the shackle pin is located in its closed position.
