Abstract: Longitudinal lock devices for cargo in aircraft having a locking box fastened beneath the floor of an aircraft include a locking latch connectable to the cargo and coupled to a bar mechanism disposed inside the locking box. The locking latch is moveable in a direction towards extraction of the cargo in flight. The bar mechanism is fixed to the locking box and includes a puppet arm articulated on a second pivot wand a puppet follower articulated on a first pivot, whereby each of the pivots is operably fastened to the locking box (9). The puppet arm comprises a cam profile on a face there of which is cooperative with a puppet roller connected to an electro-mechanical actuator linear by means of a drive rod. The articulations moving the bar mechanism responsively determine locked, armed and released positions for the device.

Abstract: There is described a longitudinal lock device for cargo in aircraft endowed with a locking box which is fastened beneath the floor of an aircraft, the longitudinal lock device for cargo in aircraft comprising a locking latch associated to the cargo and coupled to a bar mechanism disposed inside the locking box, the locking latch being moved towards the extraction of the cargo in flight; the bar mechanism being formed by the locking box acting as a fixed bar, a puppet arm articulated on a second pivot and a puppet follower articulated on a first pivot, both pivots fastened to the locking box said articulations moving the bar mechanism determining locked, armed and released positions for the device.
