A multipoint mortise lock mechanism for a swinging door, including a central cassette assembly operably coupled to an upper remote locking point assembly and a lower remote locking point assembly by a remote locking linkage. The central cassette assembly includes a housing, a deadbolt mechanism, a latchbolt mechanism, a remote locking point mechanism and an anti-slam mechanism. The anti-slam mechanism includes an anti-slam plunger that when in an extended position engages the remote locking linkage via a boss and a slot and thereby inhibits movement of the remote locking linkage whereby deployment of the remote locking point assemblies is prevented. The deadbolt mechanism includes a deadbolt extendible from the central cassette that is independently operable from the remote locking point mechanism. The deadbolt mechanism further includes an anti-back drive mechanism.

1. A multipoint mortise lock mechanism for a swinging door, comprising: a central cassette assembly operably coupled to at least one remote locking point assembly by a remote locking linkage;the central cassette assembly including a housing, a deadbolt mechanism, a latchbolt mechanism, a remote locking point mechanism and an anti-slam mechanism;the anti-slam mechanism including an anti-slam plunger that when in an extended position engages the remote locking linkage and thereby inhibits movement of the remote locking linkage so that deployment of the remote locking point assemblies is prevented, wherein the anti-slam plunger comprises a rotatable paddle and a detent, the rotatable paddle being shiftable between a first position in which the paddle presents a first sloped surface in a first direction and a second position in which the paddle presents a second sloped surface in a second opposing direction, the detent holding the paddle in either of the first position or the second position; andthe deadbolt mechanism including a deadbolt extendible from the central cassette and being independently operable from the remote locking point mechanism, the deadbolt mechanism further comprising an anti-back drive mechanism. 2. The multipoint mortise lock mechanism as claimed in claim 1, the deadbolt anti-backdrive mechanism further comprising a spring loaded pawl biased to bear against the deadbolt, wherein the deadbolt presents a notch into which the pawl engages when the deadbolt is extended, the pawl inhibiting backdriving of the deadbolt andwherein the deadbolt driver presents a lifter that lifts the pawl from the notch when the deadbolt driver is shifted thus permitting retraction of the deadbolt when desired. 3. The multipoint mortise lock mechanism as claimed in claim 1, wherein the remote locking linkage further comprises a slidable member coupled to the upper remote locking point assembly or the lower remote locking point assembly and a torsion spring coupled to the slidable member and arranged to hold the slidable member in an upper position or a lower position. 4. The multipoint mortise lock mechanism as claimed in claim 1, wherein the latchbolt mechanism further comprises a latchbolt and a spring biasing the latchbolt outwardly, the latchbolt including a polygonal portion that interfaces with a similarly shaped polygonal opening in the cassette housing and a cylindrical portion, the latchbolt being rotatable between a first position and a generally diametrically opposed second position whereby the latchbolt can be changed from a first handedness to a second opposed handedness. 5. The multipoint mortise lock mechanism as claimed in claim 1, wherein the remote locking linkage comprises an upper drive bar and a lower drive bar. 6. The multipoint mortise lock mechanism as claimed in claim 5, wherein the upper drive bar and the lower drive bar are operably coupled to operate in opposite directions by a drive bar linkage. 7. The multipoint mortise lock mechanism as claimed in claim 6, wherein the drive bar linkage comprises a first rack coupled to the upper drive bar and a second rack coupled to the lower drive bar, the first rack being operably coupled to the second rack by a pinion. 8. The multipoint mortise lock mechanism as claimed in claim 6, wherein the drive bar linkage comprises a pivotable lever linked at a first end thereof to the upper drive bar and linked at a second end thereof to the lower drive bar. 9. The multipoint mortise lock mechanism as claimed in claim 1, wherein the anti-slam mechanism further comprises a pawl engageable to a slot in the anti-slam plunger when the anti-slam plunger is retracted, the pawl further engaging a clearance slot in a stop bolt when the anti-slam plunger is extended, the pawl, when engaged in the anti-slam plunger slot and disengaged from the stop bolt slot, freeing the slop bolt to translated thereby enabling movement of a deadbolt driver to extend the deadbolt, the stop bolt further being translatably shiftable to engage a stop bar operably coupled to a handle thereby preventing operational movement of the handle when the stop bolt is engaged to the stop bar. 10. The multipoint mortise lock mechanism as claimed in claim 1, wherein the latchbolt further comprises a lubrication strip that protrudes relative to all surfaces of the latch bolt that are configured to make contact with a strike. 11. The multipoint mortise lock mechanism as claimed in claim 10, wherein the lubrication strip protrudes relative to four generally planar surfaces of the latchbolt that are configured to make contact with a strike. 12. A multipoint mortise lock mechanism for a swinging door, comprising: a central cassette assembly operably coupled to at least one remote locking point assembly by a remote locking linkage;the central cassette assembly including a housing, a deadbolt mechanism, a latchbolt mechanism, a remote locking point mechanism and an anti-slam mechanism;the anti-slam mechanism including an anti-slam plunger that when in an extended position engages the remote locking linkage and thereby inhibits movement of the remote locking linkage so that deployment of the remote locking point assemblies is prevented, andthe deadbolt mechanism including a deadbolt extendible from the central cassette and being independently operable from the remote locking point mechanism, the deadbolt mechanism further comprising an anti-back drive mechanism, wherein the deadbolt mechanism further comprises a deadbolt driver having a first portion coupled to the deadbolt that extends the deadbolt upon shifting from a first position to a second position and a second portion that engages a blocker link coupled to a stop bar so as to shift the stop bar to block rotation of a handle mechanism coupled to the latchbolt mechanism when the deadbolt driver is in the second position. 13. The multipoint mortise lock mechanism as claimed in claim 12, wherein the deadbolt driver presents a lobe and comprises a spring biased against the lobe of the deadbolt driver, the spring acting to hold the deadbolt driver in the first position or in the second position. 14. A multipoint mortise lock mechanism for a swinging door, comprising: a central cassette assembly operably coupled to at least one remote locking point assembly by a remote locking linkage;the central cassette assembly including a housing, a deadbolt mechanism, a latchbolt mechanism, a remote locking point mechanism and an anti-slam mechanism;the anti-slam mechanism including an anti-slam plunger that when in an extended position engages the remote locking linkage and thereby inhibits movement of the remote locking linkage so that deployment of the remote locking point assemblies is prevented, andthe deadbolt mechanism including a deadbolt extendible from the central cassette and being independently operable from the remote locking point mechanism, the deadbolt mechanism further comprising an anti-back drive mechanism; the mortise lock mechanism further comprising an operating handle and a compression spring, the compression spring being captured in two slidably opposed cavities including a first cavity and a second cavity, the first cavity being defined by a crank return bar and the second cavity being defined by a crank return housing, the compression spring biasing the operating handle to a neutral position from either an upwardly rotated position or a downwardly rotated position by biasing interaction with the first cavity and the second cavity.
