ABSTRACT:
A conventional mortise lock is provided with a visual status indicator to show whether the room is occupied or vacant. The mortise lock output, which operates the deadbolt, is used to linearly move an indicator slide positioned on the outside of the door by a rotating indicator spindle which is in communication with the mortise lock output and indicator slide. The visual status indicator has an opening which is covered by a transparent high strength, impact resistant material such as LEXAN plastic. A preferred embodiment combines the outer lever door handle controller and visual status indicator in a single housing.
