High-Security Enclosure

A high-security enclosure, comprising:

• a base;
• a cover pivotally mounted to said base;
• a lock system for locking said cover to said base;
• said lock system including a base portion on said base and a cover portion on said cover;
• said lock system base portion including one or more elongated fixed lock bars on an inside of said base, said one or more fixed lock bars each including one or more catch portions and one or more elongated stiffener portions stiffening one or more wall portions of said base;
• said lock system cover portion including one or more movable lock bars on an inside front wall of said cover, said one or more movable lock bars being generally perpendicular to, and arranged to engage, said one or more fixed lock bar catch portions;
• said lock system cover portion further including a lock bar retraction assembly coupled to said one or more movable lock bars for retracting said movable lock bar(s) out of engagement with said one or more fixed lock bars, said movable lock bars and said lock bar refraction assembly being oriented generally parallel to said cover front wall;
• and
• a security drive mechanism coupled to said lock bar retraction assembly to drive said lock system.

A high-security enclosure, comprising:

• a base;
• a cover that is both pivotally and slidably mounted to said base;
• a lock system for locking said cover to said base;
• said lock system including a base portion on said base and a cover portion on said cover;
• said lock system base portion including a pair of first and second fixed lock bars arranged in mutually parallel spaced relationship with each other;
• said lock system cover portion including one or more sets of movable lock bars arranged in mutually parallel spaced relationship with each other;
• each movable lock bar set including first and second movable lock bars that are generally perpendicular to, and arranged to respectively engage, said first and second fixed lock bars;
• said lock system cover portion further including a lock bar retraction assembly coupled to said movable lock bar sets for retracting said movable lock bars out of engagement with said fixed lock bars;
• a security drive mechanism coupled to said lock bar retraction assembly to drive said lock system;
• said fixed lock bars each include one or more catch portions for engaging a movable lock bar of said one or more movable lock bar sets, and a stiffener portion for stiffening portions of said base on which said fixed lock bars are mounted;
• said one or more catch portions and said stiffener portions being either integrally formed on a piece of bar stock, or being respectively provided by one or more catch fittings and a separate stiffener channel;
• said movable lock bars being slidable within bracket assemblies mounted on said cover, said bracket assemblies being stiff relative to portions of said cover on which said bracket assemblies are mounted to provide improved security by resisting disengagement of said lock system base and cover portions due to deformation of said cover;
• said cover being configured to enclose said base in a nested relationship and said base including one or more backplate flanges that enclose one or more portions of said cover when said cover encloses said base;
• said lock bar retraction assembly including one or more lock bar engaging members operatively coupled to said one or more movable lock bar sets and one or or more actuators arranged to drive one or more said lock bar engaging members;
• said one or more lock bar engaging members being selected from the group consisting of cams, gears, drive wheels and drive cranks;
• said first and second lock bars of said one or more movable lock bar sets being biased into said engagement with said fixed lock bars;
• and
• said security drive mechanism comprising a security lock on said refraction assembly configured to receive a security key for actuating said retraction assembly.
