Abstract
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.
