ABSTRACT:
Supports such as a pallet carrying aircraft passenger seats or a bottom of a freight container are secured to a floor structure in an aircraft. For this purpose the floor structure includes floor stringers (5) supported on and secured to floor joists (11). The stringers (5) are U-rails having an upwardly open U-cross-section with a first interlocking member (8) in the U-cross-section. An adapter (4, 13) having a present existing stud (8) and shear pin system (8A) is secured in the U-rail of the stringers (5). The adapter (4) is secured to or securable to the support by a latching (2, 3). Another adapter (13) carries rotatable rollers or roller balls that project slightly above an upwardly facing floor level to permit, for example, freight containers or seat pallets to roll along the floor. Instead of adapter (13) it is also possible to install a present existing container latch carrier (14) in the present stringer (5).
