A convertible door latch assembly convertible between a non-locking configuration and a locking configuration. The convertible door latch assembly including a bolt housing, a bolt slidably engaging the bolt housing and having a first slot and a second slot, a drawbar slidably engaging the first slot and the bolt housing, a dead latch stop being engagable in the first slot to hold the drawbar in the first slot when the convertible door latch assembly is in the locking configuration, a plunger being slidably engagable in the second slot and being movable between an extended position and a retracted position when the convertible door latch assembly is in the locking configuration, and a pull slidably positionable within the first slot and moveable relative to the bolt when the convertible door latch is in the non-locking configuration.

Convertible door lock latch mechanism

An interconnected lock assembly which can remotely engage a mechanism to couple operation of an inside handle to operation of an outside handle to enable the door to be unlocked from the outside of the door without requiring a key. The interconnected lock assembly is mounted in a door and comprises a first lock assembly including an inside handle and an outside handle, and a second lock assembly interconnected to the first lock assembly. The second lock assembly comprises a deadbolt assembly operably connected to a deadbolt latch having a deadbolt movable between an extended position and a retracted position. Rotation of the inside handle operates to move the deadbolt into a retracted position. The interconnected lock assembly further comprises a remote unlocking mechanism selectively engageable to automatically couple the outside handle to the inside handle such that rotation of the outside handle moves the deadbolt into a retracted position thus unlocking the door.

Interconnected lock with remote unlocking mechanism

A push button door locking mechanism including a push button mounted on a push button carrier housed within an inside spindle of a door lock assembly, a main retractor co-rotatingly attached to the spindle, and an inner cam aligned axially with the push button carrier. The inner cam has a flange portion extending substantially perpendicularly from a driver bar portion of the inner cam. The locking mechanism also includes a locking catch assembly having a first end and a second end. The first end includes a head portion formed to matingly engage the push button carrier. The second end is coupled to a locking wing. The locking catch assembly has a locked position wherein the locking wing matingly engages the flange preventing rotation of the flange with respect to the main retractor and an unlocked position allowing rotation of the flange with respect to the main retractor.
