Abstract
An improved key ring lock assembly including a lock mechanism having an open position and a locked position which is formed by at least a lock barrel, a lock cylinder fitted within the lock barrel, the lock cylinder having a front key way and a lock mechanism contained within the lock cylinder operable by an appropriate key. The lock cylinder terminates in a lock shaft at the back end which is rotatable in response to the manipulation of the lock mechanism via the key. A lock collar is contained within the lock barrel immediately rearward of the lock cylinder and includes a lock shaft receiving aperture to receive the lock shaft and be operable in response to the rotatable movement of the lock mechanism. The lock collar includes an elongate stud mounted on the back end which includes a pair of opposed pin receiving channels formed therein. The lock barrel includes a locking ledge circumferentially positioned along the inner wall and adjacent the back end thereof. The locking ledge is interrupted by a pair of opposed slots positioned approximately 180 degrees from one another and when in the open position, are positioned in registry with the pin receiving channels formed in the lock stud. A key cable with opposed ends is provided which includes a pair of lock pins secured to the ends thereof, each lock pin having a lock groove being sized to allow the locking ledge to ride within the confines thereof.
