Claim Text:
1. A door lock assembly incorporating a deadbolt and latch bolt assembly for incorporation in a door and having a uni-directional operative centered key cylinder for pivotal functioning for keyless operation of said deadbolt from an unlocked position to a locked position of said deadbolt, said door lock assembly comprising: a key cylinder provided fully centered in said door lock assembly, said key cylinder being both vertically and horizontally aligned on a center axis in said door lock assembly, a key cylinder torque blade extending from said key cylinder and aligned on said center axis; an actuator interlock mechanism operatively connected in the door lock assembly and provided for pivoting with said torque blade on said same center axis, said actuator interlock mechanism being pivotal on said center axis from an unlocked position corresponding to an unlocked position of the deadbolt, to a locked position corresponding to a locked position of said deadbolt, said pivotal locking movement of said actuator interlock mechanism being made in one direction, regardless whether the door lock assembly and its said actuator interlock mechanism is installed for a right hand or left hand hung door; a ring pivotally mounted upon the door lock assembly and pivotal with the actuator interlock mechanism from an initial position of said ring to a second position thereof; said actuator interlock mechanism and ring being integrally structured as one piece for simultaneous pivot during actuation; said actuator interlock mechanism integrally connected to said ring for conjoint pivot therewith, said actuator interlock mechanism being configured and arranged for contact with said torque blade when the door lock assembly is in an unlocked position and upon rotation of the ring from its initial position, and turning in pivotal movement to pivot the torque blade from an unlocked position of the actuator interlock mechanism and its associated latch bolt assembly and deadbolt to a locked position of said latch bolt assembly, and a biasing member interconnecting with the door lock assembly and said actuator interlock mechanism to urge the actuator interlock mechanism to pivot in reverse from its pressured contact with the torque blade after securing the locked position of the latch bolt assembly and its deadbolt, on either a right hand or left hand hung door; said latch bolt assembly being operable upon a turning of the ring in a pivotal mode in one direction, and the ring being rotatable only in said pivotal direction to rotate the integral actuator interlock mechanism and ring, and said torque blade from its unlocking position of the deadbolt to its locking position in its manipulation of the latch bolt assembly and its deadbolt for locking of the associated door; said latch bolt assembly being configured for installation upon either a right hand or left hand hung door with no reconfiguration of said latch bolt assembly required, said latch bolt assembly may be reversed by inverting in its installation upon a door to urge its deadbolt to lock either a right hand or left hand hung door, said latch bolt assembly incorporating a deadbolt cylindrical frame, a latch driving mechanism, said latch driving mechanism having an opening therethrough and through which said torque blade extends, and a latch operator for movement of the deadbolt during its shifting into a locked or unlocked position, the back of said cylindrical frame having a pair of apertures therein, said cylindrical frame, having upper and lower edges and the pair of apertures being arranged centrally between said upper and lower edges of the back of said cylindrical frame, the pair of apertures provided for mounting for pivotal movement of said latch driving mechanism therein, said torque blade of said door lock assembly extending through said latch driving mechanism, the apertures at the back of said cylindrical frame and the opening through the latch driving mechanism being on the same center axis as the key cylinder and said torque blade, such that when the ring is manually pivoted, causes pivoting of the torque blade and the actuator interlock mechanism, the latch bolt assembly will force the deadbolt into a locked position, regardless whether provided upon a right hand or left hand hung door because of its fully centered location of the key cylinder.
