Collinear latch and lock

An aircraft lavatory door system, comprising:

• an aircraft lavatory door;
• and
• a door securing device coupled to the aircraft lavatory door, the door securing device comprising:
• a strike with a lock bolt disposed at or defined by an end of the strike, the strike configured to actuate linearly along an axis;
• a latch pawl configured to surround at least a portion of the strike and linearly actuate along the same axis as the strike;
• a housing that defines a cavity configured to house at least a portion of the strike and at least a portion of the latch pawl;
• at least one spring disposed at least partially within the housing, the at least one spring configured to bias the latch pawl towards a latched position;
• a latch cam disposed at least partially within the housing, the latch cam configured to actuate the latch pawl towards an unlatched position when the latch cam is turned;
• a handle coupled to the latch cam and configured to turn the latch cam;
• a lock trigger coupled to the strike for linearly actuating the strike between locked and unlocked positions;
• and
• a magnetic detent system comprising:
• at least one selector magnet coupled to or at least partially embedded within the strike;
• and
• a plurality of position magnets coupled to or at least partially embedded within the housing, the plurality of position magnets including at least a first magnet corresponding to the unlocked position, a second magnet corresponding to the locked position, and a third magnet disposed in between the first magnet and the second magnet, wherein the first and second magnets are configured to attract the at least one selector magnet, and the third magnet is configured to repel the at least one selector magnet.

A system for latching and locking, comprising:

• a strike with a lock bolt disposed at or defined by an end of the strike, the strike configured to actuate linearly along an axis;
• a latch pawl configured to surround at least a portion of the strike and linearly actuate along the same axis as the strike;
• a latch cam configured to actuate the latch pawl from a latched position to an unlatched position when the latch cam is turned;
• and
• a magnetic detent system comprising:
• at least one selector magnet coupled to or at least partially embedded within the strike;
• and
• a plurality of position magnets coupled to or at least partially embedded within a housing that surrounds at least a portion of the strike, the plurality of position magnets including at least a first magnet corresponding to the unlocked position, a second magnet corresponding to the locked position, and a third magnet disposed in between the first magnet and the second magnet, wherein the first and second magnets are configured to attract the at least one selector magnet, and the third magnet is configured to repel the at least one selector magnet.
