Abstract: A latch assembly (10) is mounted to a follower door (275) of a double door (257). When the follower door (275) is closed while a primary door (259) of the double door (257) is closed, an actuation latch (131) of the latch assembly (10) is moved from a releasing position to a pressing position to move a latch (231) of the latch assembly (10) to a latching position engaged in a groove (37, 300) in a door frame (31) or in the ground (299). When the actuation latch (131) is moved from the releasing position to the pressing position while the follower door (275) is not in the closed position, the latch (231) is retained in an unlatching position, avoiding damage to the latch assembly (10).

Abstract: An anti-pick latch assembly (10) is mounted to a follower door (275) of a double door (257). The latch assembly (10) includes an actuation latch (131) normally extending beyond an end face (291) of the follower door (257) and a latch (231) movable between an unlatching position received in the follower door (275) and a latching position extending out of the follower door (275) into a groove (37) in a door frame (31). When the follower door (275) is closed while a primary door (259) of the double door (257) is closed, the actuation latch (131) is actuated to move a limiting member (90) to a locking position, moving the latch (231) of into the groove (37) of the door frame (31). The limiting member (90) in the locking position prevents the latch (231) from moving out of the groove (37) while the latch (231) is picked.

Abstract: A multipoint mortise lock assembly includes an extended face piece mounted flush along the edge of a door, a mortise lock connected to the face piece, and a pair of hook bolt latch mechanisms mounted to the face piece above and below the mortise lock. An elongated actuator, which is preferably a flat rod slidingly mounted to the back of the face piece, acts to extend and retract the hook bolts in synchronism with a deadbolt in the mortise lock. The actuator is connected between a deadbolt arm in the mortise lock, which drives the deadbolt, and the hook bolt latch mechanisms. The deadbolt arm is driven conventionally, such as by a key or a thumb latch, and the design allows one hand operation of the multipoint mortise lock assembly.

Abstract: A multipoint lock assembly for securing a door that is hinged along one edge and that has a free, swingable edge opposite the hinged edge. The assembly includes a central latch and at least one remote latch vertically spaced therefrom along the free edge of the door. The retraction of all the latches is controlled by a central latch driving mechanism in response to a manual operation either of an exterior thumb-operated latch lever or of an interior doorknob. A deadbolt is also located proximate the central latch. The deadbolt is controlled either by an externally accessed cylinder lock in response to a manual insertion and rotation of a key or by a manual rotation of an interior-mounted thumb-turn. While the deadbolt is extended, the thumb-operated latch lever and the doorknob are inoperable. At least one of the latches includes a latch trigger. This is tripped when the door is closed, allowing the latch of which it is a part to assume a superextended position.

Abstract: A latch mechanism for a door has first and second latches, a handle, a first cam connected to the first and second latches, a second cam and a third cam connected to the handle such that movement of the handle operates the first and second latches by transmitting movement from the third cam to the first cam through the second cam. One or more rods may be used to connect the latches and or handle. The first handle may simultaneously operate the first and second latches. A second handle may also be provided for simultaneously operating the latches. The first cam includes a finger and the second cam includes a projection that is selectively engageable with the finger. Movement of the third cam causes movement of the projection which in turn causes movement of the first cam when the projection is engaged with the finger of the first cam. The first and second latches may be locked by disengaging the projection and the finger.

Abstract: A multi-point locking system (10) has a lock case (11) with a door front edge (20), a latch (65), a blocking bolt (80) and two longitudinally movable push rods (30, 31) connected to one another by a connecting element (40) with locking elements such as eccentrically mounted roller pins (33) engaging in striking plates (34). The connecting element (40) has an engagement recess (46), is arrestable by a spring-loaded engaging element (52) against a compression spring (48) in a pretensioned opening position, and is releasable from this arrested position by direct operation of the locking elements (33) in the longitudinal direction of the door front edge. The striking plates (34) in the entry area (36) of the locking elements (33) have inclined stop surfaces (37) exerting a force (F) on the roller pins (33) in the closing direction (Y). The slidingly guided bolt (80) blocks the locking system (10) indirectly via a flexibly mounted rocker (91) using a closing element (81), for example a locking cylinder.

Abstract: An improved multipoint lock assembly is provided for securing a swinging door in a tightly closed condition. The multipoint lock assembly includes a main actuator cartridge for retracting a plurality of latch pins mounted at vertically spaced positions along a free side edge of the swinging door, in response to rotational movement of indoor and outdoor lever handles. A trigger assembly retains the latch pins in a retracted position in response to lever handle rotation to open the door, and includes a trigger pin for engaging the adjacent door jamb upon door closure to release the latch pins for spring-loaded movement to an advanced position. The advanced latch pins engage ramped strike plates on the door jamb to draw in and tightly retain the closed door against the door jamb. When the latch pins are advanced, a security deadbolt on the main actuator cartridge can be thrown to positively lock the door.

Abstract: A lock mechanism for a dead bolt assembly. The lock assembly includes a conventional key actuated cylinder for mounting outside the door for extending and retracting the dead botl between a locked and an unlocked position. An exterior thumb turn assembly is accessible from the exterior of the door and includes a rotatable actuator arm which is connected to a pushing link for pushing the dead bolt from its retracted to its extended position. The exterior thumb turn, however, does not permit the retraction of the dead bolt, but only permits its extension.
