ABSTRACT:
A door lock device has an inside handle assembly and an outside handle assembly. A latch is positioned between the two handle assemblies and there is a spindle which is in rotatable engagement with both handle assemblies and in operable engagement with the latch such that rotation of either handle assembly moves the latch between extended and retracted positions. The inside handle assembly includes an axially movable locking element. A turn bar extends within the spindle and is connected to the locking element. Axial movement of the locking element causes rotation of the turn bar with rotation of the turn bar releasing the spindle from engagement with the outside handle assembly whereby rotation of the outside handle assembly will not rotate the spindle nor move the latch between extended and retracted positions.
