ABSTRACT:
An anchor fitting assembly for securing objects on an elongated track. The track is of the type commonly used in aircraft and in various vehicles to secure seats, wheelchairs, cargo and other objects. The track has an elongated groove which has a bell-shaped profile. The top of the groove is open and has a series of opposed tabs and semicircular faces. There are many styles of fittings which are placed in such tracks and secured to the tracks. The anchor fitting assembly of the present invention has a securable fitting which has a flared based held beneath the opposed tabs of the groove. The fitting is prevented from sliding along the track by a pair of buttons which are inserted downwardly into two opposed semicircular openings adjacent the securable fitting. When an object is screwed onto the securable fitting it holds down the buttons preventing them from coming out of the semicircular openings. Two securable fittings may be placed in adjacent tabs by using the anchor fitting assembly of the present invention.
