Abstract: A self-adjusting lock has a keeper stud with a base that is mounted in a recess in a keeper assembly so that it can slide in four directions. As the bevelled keeper stud is pressed into an opening in a latch assembly, the stud self-adjusts in the necessary direction to achieve alignment. A spring pressing the base against a surface causes the base, and so the keeper stud, to be frictionally held in its new position. The keeper stud has a series of spaced ratchet teeth, axially separated from one another, any of which can interengage with the latch mechanism. Thus, the lock is adjusted in this direction each time the lock is closed, resulting in a lock self-adjustable in six directions.
