Abstract
A track fastener apparatus for use with a locking track of the type used to secure a seat or cargo apparatus to the floor of an aircraft. The track includes a slot, and the upper walls of the slot have regularly spaced-apart enlarged openings separated by relatively narrower track slot segments defining locking segments. The track also includes a channel for carrying wiring along the length of the aircraft. The track fastener apparatus includes a housing. A screw member cooperates with the track fastener housing and the locking wedge to perform first and second functions in distinct first and second locking wedge positions. In the case of the first position the locking wedge is not completely positioned in alignment with and into the one enlarged opening, preventing the locking wedge from being tightened into the track. In the case of the second position the locking wedge is positioned in alignment with and into the enlarged opening, permitting the locking wedge to be tightened into the track. The track fastener assembly includes outwardly extending braces for preventing spreading and distortion of the walls of the locking track.
