Abstract
An ambidextrous vertical inverted handed cam lock for cabinet doors and drawers has a conventional pin tumbler cylinder and plug assembly. An arcuately movable bolt is journaled for rotation about a rearwardly extending portion of the plug. A conventional lazy cam drives the bolt. An arcuately repositionable bolt rotation limiter provides either left hand or right hand throws for the bolt while simultaneously allowing for inverted vertical use.

An ambidextrous cam lock for cabinet doors and drawers, comprising:
- a cylindrical plug defining front and rear ends and having a longitudinally directed keyway and a plurality of radially directed pin tumblers in communication with the keyway;
- an elongated cylinder having a plurality of radially directed, spring loaded top pins and an off-center, longitudinal bore therein for rotatably receiving the plug;
- a lazy cam journaled for rotation with the plug;
- a selectively positionable bolt rotation limiter having a forwardly projecting pin on the bolt rotation limiter for receipt in two bores angularly displaced on the rear end of the cylinder for selectively mounting the bolt rotation limiter adjacent to the rear end of the cylinder in a plurality of angular positions;
- and,
- an angularly moveable bolt journaled for rotational movement about the plug, the bolt having a first structure thereon for engagement with the lazy cam and a second structure thereon for engagement with the bolt rotation limiter, wherein the first and second structures are forwardly and rearwardly projecting pins positioned so that the lazy cam drives the bolt and the bolt rotation limiter limits the angular travel of the bolt.
