Abstract
A door latch assembly configured to be used in an aircraft lavatory door. The door latch assembly includes a housing that includes a housing interior, a switch member operatively associated with the housing that is rotatable between a first position and a second position, and a locking bolt that is movable linearly between an unlocked position and a locked position. Rotation of the switch member from the first position to the second position moves the locking bolt from the unlocked position to the locked position.
Claims9
A door latch assembly comprising:
- a housing that includes a housing interior,
- a switch member operatively associated with the housing that is rotatable between a first position and a second position,
- a locking bolt that is movable linearly between an unlocked position and a locked position,
- a gear train operatively connected between the switch member and the locking bolt,
- wherein rotational motion of the switch member is converted to linear motion of the locking bolt, such that rotation of the switch member from the first position to the second position moves the locking bolt from the unlocked position to the locked position, and
- an override assembly that includes a main body portion and a finger lid hingedly connected to the main body portion, wherein the finger lid is pivotable between a stowed position and a deployed position, wherein rotational motion of the finger lid is converted to linear motion of the locking bolt by the gear train, such that rotation of the finger lid from a first position to a second position moves the locking bolt from the unlocked position to the locked position.

A door latch assembly comprising:
- a housing that includes a housing interior and an interior indicator window,
- a switch member operatively associated with the housing that is rotatable between a first position and a second position,
- a locking bolt that is movable linearly between an unlocked position and a locked position,
- a gear train operatively connected between the switch member and the locking bolt, wherein rotational motion of the switch member is converted to linear motion of the locking bolt, such that rotation of the switch member from the first position to the second position moves the locking bolt from the unlocked position to the locked position,
- at least a first indicator member that is rotatable with the switch member between the first position and the second position, wherein the first indicator member includes a locked portion and an unlocked portion, wherein the housing includes an exterior indicator window, wherein when the switch member is in the locked position the locked portion of the first indicator member is visible through the exterior indicator window, and wherein when the switch member is in the unlocked position the unlocked portion of the first indicator member is visible through the exterior indicator window, wherein when the switch member is in the locked position the locked portion of the indicator member is visible through the interior indicator window, and wherein when the switch member is in the unlocked position the unlocked portion of the indicator member is visible through the interior indicator window,
- a rotating member that is rotatable with the switch member between the first position and the second position, wherein the rotating member includes an unlocked indicator window and a locked indicator window, wherein the unlocked indicator window is at least partially aligned with the interior indicator window and the exterior indicator window when the switch member is in the first position, and wherein the locked indicator window is at least partially aligned with the interior indicator window and the exterior indicator window when the switch member is in the second position.
