Abstract: A locking system provides multiple lockable latching mechanisms that are collectively operable and lockable from a central actuation mechanism. Each latching mechanism can be positioned and actuated independent of the positioning of others of the latching mechanisms. In particular, the latching mechanisms need not be aligned with one another. The system uses flexible connectors between the central actuation mechanism and the respective latching mechanisms. The flexible connectors can have different respective lengths.

Abstract: Disclosed is a convertible motorized latch that may be configured in either of a slam latch or a dead bolt latch configuration, just by desired selection and replacement of a minimal number of components, and which may be used on new (oem) equipment or in retrofit applications.

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.
