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 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;
- an actuator mechanism operable to cause rotation of the first latch member to the unlatched operating state;
- and
- a fault detection assembly operable to detect a fault operating condition of at least one of the latch lock assembly and the base frame.
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 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;
- an actuator mechanism operable to cause rotation of the first latch member to the unlatched operating state;
- and
- a fault detection assembly operable to detect a fault operating condition of at least one of the latch lock assembly and the base frame.
A computer-implemented method of operating a closure structure system having a latch lock assembly, the computer-implemented method comprising:
- monitoring an operating condition of the latch lock assembly;
- and
- causing, in response to receipt of an electric signal indicative of a detected fault operating condition of the latch lock assembly, display of at least a visual warning of the detected fault operating condition.
