Abstract: An interconnection assembly includes a chassis, and cam plates that are rotatably coupled to the chassis to pivot about a plurality of rotational axises. An upper cam plate is operatively coupled to a deadbolt. The upper cam plate has a cam surface. A lower cam plate is rotatably coupled to the chassis to pivot about a second rotational axis. The lower cam plate is operatively coupled to an interior latch bolt handle. The lower cam plate has a cam slot. A linkage bar is rotatably coupled to the chassis to pivot about a pivot axis. The linkage bar has a first linkage portion having a first cam follower configured to operatively engage the cam surface of the upper cam plate and has a second linkage portion having a second cam follower operatively received in the cam slot of the lower cam plate.
