Abstract
A high security deadbolt assembly for a door which bolt has a housing extending from the edge of the door inwardly of the transverse bore between the door surface. A deadbolt is reciprocable in the housing and has a recess at its inner end. A cylindrical drive member is rotatively supported in the housing and is located with or is aligned with the deadbolt recess. The drive member carries a stop and is connected to the bolt by a linkage. When locked, a substantial portion of the length of the bolt remains engaged in the bolt housing and door so that attempts at forcing the bolt to the unlocked position are resisted by the stop which stop engages an internal surface of the bolt recess. The components are made from high strength materials and the deadbolt assembly may be retrofit to existing lock cylinders with a minimum of installation modifications.
