Abstract

A locking mechanism for latching cargo pieces to a loading floor of aircraft has two latches housed in a common latch housing. The latching claws face in opposite directions. The latches rotate on journal shafts arranged parallel to the longitudinal axis of the aircraft with a lateral on-center spacing between the journal shafts. Tension springs act eccentrically to hold the latches in their extended locking position. In the locking position the latches support each other by bearing against respective stops. An inclined ramp, provided on each latch and extending in the loading direcion, cooperates with a connecting lever joint to assure that the latches can be rolled over by cargo pieces of full width, while pieces of half the full width are arrested in lateral and vertical directions when the mechanism is located between two pieces of half width closely spaced from each other.
