ABSTRACT:
A deadbolt lock is adaptable for installation in doors of various thicknesses. The lock body and interior rosette are established at a fixed position with respect to the interior surface of the door in which the lock is mounted. A cylindrical threaded coupler is threaded to an extension of the exterior keyway-carrying rosette of the lock and the coupling between the threaded cylinder and the threaded extension of the rosette are adjusted in accordance with the thickness of the door to which the lock is installed. The interior threaded coupling cylinder is then inserted within the bore of the lock, the mounting being achieved without interference with the deadbolt throw/retract mechanism interior of the lock body. The assembly is secured by compressing the door between interior and exterior decorative plates, the compression resulting by the drawing of the exterior rosette against the outer decorative plates by engaging a retaining nut with threads of the interior coupling cylinder which protrudes through the interior side of the lock body. Both the exterior and interior keyway-carrying rosettes are fastened by means of concealed non-rotatable couplings. The door must be in its opened position before any access may be gained to the interior of the lock. An extremely strong lock mounting arrangement results which inhibits tampering with the lock when the door is closed.
