Abstract: A lock assembly having a first body portion configured to lock with a second body portion. The first body portion includes a first end having a first aperture and a second aperture aligned in perpendicularly intersection with the first aperture. The second aperture retains a pair of locking balls. The second body portion includes an aperture configured to receive the first end of the first body portion. The aperture of the second body portion also includes a circumferential groove configured to receive a portion of the pair of locking balls in a locked position of the first body portion with the second body portion. A keyway locking cylinder is configured to axially drive a beveled point of an extension into the first aperture of the first body portion and force the pair of locking balls in a radially outward direction into the locked position with the circumferential groove.

Abstract: A barrel lock for locking two structures together that includes two lock portions, each portion being generally cylindrical and elongated, one of which is substantially solid and one of which is substantially hollow. The first lock portion has one section of a substantially greater diameter than a second section, the two sections being separated by a beveled annular shoulder. The smaller diameter section is provided with a cylindrical axial aperture into which are disposed a plurality of spheres adapted to be received in apertures in the first portion of the lock, and also adapted for engagement in an annular groove on the interior surface of the second portion of the lock, the locking balls thereby effectively locking the two portions of the lock together. The second portion is axially aligned with the first portion and is provided with a keyway adapted for movement in a rotatable and axially slideable fashion within said second portion.
