Abstract
A deadbolt lock and a deadbolt which will extend automatically whenever a container is locked by virtue of a rigid portion of the container engaging a trigger element extending from the end face of the bolt and causing the release of an outer bolt portion is shown and described herein. The release of the outer bolt of the bolt assembly allows the outer bolt to project outwardly and to lock the container notwithstanding the fact that the bolt has not been reset by the operator of the lock. The bolt is self-contained and can be substituted into many existing lock mechanisms of the mechanical type and into some of the existing electronic dial combination locks, to provide the auto-locking enhancement.
