Abstract
A reversible door lock having a status indicator is provided. The door lock may include an escutcheon plate having a window through which the status of the door on a status indicator ring may be view. When the door is locked and unlocked via an actuator (e.g., a thumbturn) the door status indicator ring may change positions. The lock may include a drive wheel operatively coupled to the actuator and the status indicator ring. The drive wheel may be capable of moving between a first orientation and a second orientation relative to the status indicator ring such that the door lock operates in a first direction (e.g., a right-hand direction) when the drive wheel is in the first orientation and in a second direction (e.g., a left-hand direction) when the drive wheel is in the second orientation.
