Abstract
A latch lock assembly to facilitate movement of a closure structure between a stowed position and an open position. The latch lock assembly includes fault detection and electro-mechanical monitoring of components of the latch lock assembly. In the event of a detected fault operating condition by the latch lock assembly, a manual override mechanism may be employed to enable a user to advance the closure structure from the stowed position to the open position.
Claims20
A latch lock assembly, comprising:
- a housing;
- a first latch member pivotably mounted to the housing and a second latch member pivotably mounted to the housing, each latch member for rotation between a latched operating state to maintain a base frame of a closure structure system in a stowed position and an unlatched operating state to initiate advancement of the base frame from the stowed position to an open position;
- a first trigger member pivotably mounted to the housing and operable to cause rotation of the first latch member;
- a second trigger member pivotably mounted to the housing and operable to cause rotation of the second latch member;
- an actuator mechanism operable to cause rotation of the first trigger member and the second trigger member to cause rotation of both the first latch member and the second latch member to the unlatched operating state;
- a fault detection assembly operable to detect a fault operating condition of at least one of the latch lock assembly and the base frame;
- and
- a manual override mechanism to advance the base frame from the stowed position to the open position in response to the detected fault operating condition, the manual override mechanism operatively connected to the first trigger member and the second trigger member to actuate both the first trigger member and the second trigger member in response to the detected fault operating condition.

A closure structure system, comprising:
- a base frame moveable between a stowed position and an open position;
- and
- a latch lock assembly including:
- a housing;
- a first latch member pivotably mounted to the housing and a second latch member pivotably mounted to the housing, each latch member for rotation between a latched operating state to maintain the base frame in a stowed position and an unlatched operating state to initiate the base frame advancing from the stowed position to an open position;
- a first trigger member pivotably mounted to the housing and operable to cause rotation of the first latch member;
- a second trigger member pivotably mounted to the housing and operable to cause rotation of the second latch member;
- an actuator mechanism operable to cause rotation of the first trigger member and the second trigger member to cause rotation of both the first latch member and the second latch member to the unlatched operating state;
- a fault detection assembly operable to detect a fault operating condition of at least one of the latch lock assembly and the base frame;
- and
- a manual override mechanism to advance the base frame from the stowed position to the open position in response to the detected fault operating condition, the manual override mechanism operatively connected to the first trigger member and the second trigger member to actuate both the first trigger member and the second trigger member in response to the detected fault operating condition.

A latch lock assembly, comprising:
- a housing;
- a first latch member pivotably mounted to the housing for rotation about a first pivot axis;
- a second latch member pivotably mounted to the housing for rotation about the first pivot axis, wherein each latch member rotates between a latched operating state to maintain a base frame of a closure structure system in a stowed position and an unlatched operating state to initiate advancement of the base frame from the stowed position to an open position;
- a first trigger member pivotably mounted to the housing for rotation about a second pivot axis and operable to cause rotation of the first latch member to the unlatched operating state;
- a second trigger member pivotably mounted to the housing for rotation about the second pivot axis and operable to cause rotation of the second latch member to the unlatched operating state;
- an actuator mechanism operable to cause rotation of the first trigger member and the second trigger member about the first pivot axis;
- and
- a manual override mechanism operatively connected to the first trigger member and the second trigger member such that in the event of a fault operating condition of the closure structure system, the manual override mechanism causes rotation of both the first trigger member and the second trigger member which causes rotation of the first latch member and the second latch member to the unlatched operating state in order to initiate advancement of the base frame from the stowed position to the open position.
