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.

Multi-point mortise lock mechanism for swinging door

A multi-point lock assembly with shoot bolts adapted to fit a wide range of door heights with a limited number of standard components. The shoot bolts of the assembly can be trimmed to length and attached to other standard components to form the assembly.

Sliding door multipoint mortise lock with shoot bolts

A securing mechanism for a hinged sidelight panel. The securing mechanism includes a center latch bolt for latching the hinged sidelight panel and remote locking mechanisms for locking the hinged sidelight panel. A single lever handle is used to selectively retract the remote locking mechanisms and the latch bolt. At a first orientation of the handle, both the remote locking mechanisms and the latch bolt are engaged. At a second orientation of the handle, the latch bolt remains engaged, but the remote locking mechanisms retracted. At a third orientation, both the remote locking mechanisms and the latch bolt are disengaged. The orientation of the handle informs an observer whether the locks are engaged. In one embodiment, the full rotation is about 90&#xb0;, enabling the use of longer lever handles without interference from door frames.

Hardware for a hinged light panel

A multipoint lock for sliding doors. The multipoint lock mounted to a sliding door generally includes an active locking device having an active latch, and two passive locking devices, each having a passive latch. The latches are independently depth adjustable relative to an edge of the sliding door. The active locking device further includes sets of fastener apertures for receiving and securing a handle assembly thereto in at least two different positions. A lever having an actuator pin of the handling assembly can be positioned at various locations on the handle assembly such that fastener apertures of the handle assembly align with a different set of handle apertures of the active locking device depending on the position of the lever, Actuation of the active locking device by movement of the lever shifts the active latch and the passive latches simultaneously between locked and unlocked positions.

Multipoint lock mechanism

A multi-point latch assembly having a single adjustment point for shifting the position of two or more latching members. The latch mechanism includes a housing and a carrier assembly received in the housing. The carrier assembly includes a pair of latch hooks. A carrier position adjustment assembly operably couples the housing and the carrier assembly such that the carrier assembly is selectively shiftable in the housing with the carrier position adjustment assembly to alter the distance the latch hooks protrude from the housing when the latch hooks are positioned in the second position. An anti-slam mechanism may also be coupled with the carrier, and may be selectively shiftable with the same adjustment mechanism.
