Door lock system

A door lock system comprising:

• a hollow metal frame having a principal surface on a front wall and at least one aperture on an interior wall;
• a door hinged to the frame and including a deadbolt extendable into the aperture of the frame;
• and
• a planar latch guard on the door covering the deadbolt and extendable over a guarded area of the principal surface of the frame, the guarded area having a first recessed surface setback from the principal surface and dimensioned to receive the latch guard so that when the door is shut the latch guard is flush with the door and the principal surface of the frame, thus providing an aesthetically attractive highly secure latch guarded door lock and frame system;
• wherein the interior wall of the frame has a second recessed surface contiguous with the first recessed surface, onto which a lock strike can be mounted, and further comprising a tube welded into the door frame, wherein the first and second recessed surfaces are on the tube.

• a door hinged to the frame and including a deadbolt extendable into the aperture of the frame;
• and
• a planar latch guard on the door covering the deadbolt and extendable over a guarded area of the principal surface of the frame, the guarded area having a first recessed surface set back from the principal surface and dimensioned to receive the latch guard so that when the door is shut, the latch guard is flush with the door and the principal surface of the frame and having a second recessed surface contiguous with the first recessed surface, onto which a lock-strike can be mounted, wherein the first and second recessed surfaces are reinforced relative to the rest of the frame so that the thickness of the walls behind the recessed surfaces are greater than the thickness of the front and interior walls of the frame, thus providing an aesthetically-attractive, highly-secure, latch-guarded door lock and frame system.
