Floor rail fixation for aircraft, has bolt supported on cap and chock forming elements drawn against bottom of rail when bolt is locked for blocking floor rail between cap and chock forming elements

摘要

The fixation has U shaped chock forming elements (20, 22) inserted via holes in a floor rail. A cap (90) is placed above the elements (20, 22) such that a bolt (66) passes through the cap. The cap has wedge forming elements (94, 96) forcing the elements (20, 22) against sides of the holes such that hollow regions (32, 34, 36, 38) of the elements (20, 22) are locked on the bottom of the rail. The bolt is supported on the cap towards bottom and the elements (20, 22) are drawn against the bottom of the rail when the bolt is locked for blocking the rail between the cap and the elements (20, 22).
