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.

Dependent claims

An anchor fitting assembly (10) for securing objects on an elongated track (11) of the type secured to a vehicle floor, said elongated track having an elongated groove with a bell shaped profile (12) with a groove floor (12') and a track groove top (13) having an edge (14) with a plurality of opposed semicircular faces (15, 15') and opposed tabs (16, 16'), said fittings comprising:

a securable fitting (17) having a stud portion (18) to which objects to be secured may be attached, a track groove top abutting length (19) below said stud portion (18) having four opposed sides, two of which sides (20, 21) which closely abut a pair of opposed tabs (16, 16'), and each of the remaining two sides (22, 23) closely abut a side of an adjacent button (24, 25), and an outwardly flared base (26') below said track groove top abutting length (19), said outwardly flared base (26) being shaped to fit downwardly between said pairs of opposed semicircular faces (15, 15') and slide sideways below said opposed tabs (16, 16') and rest on a floor (12') of said elongated groove (12);
a pair of buttons (24, 25) each button having a top surface (28), a side area (29) having a pair of opposed semicircular sides (30, 31), and at least one side portion (32) which abuts one of said remaining two sides of said track groove top abutting length (19) of said securable fitting (17), and each of said buttons having sides (33', 34') being shaped to permit the positioning of each pair of buttons (24, 25) adjacent an outwardly flared base (26') of a securable fitting (17) when said pair of buttons (24, 25) are resting on said groove floor (12') of said bell shaped groove (12) whereby when an object with a flat bottom portion is secured to said stud portion (18) of said securable fitting (17) the flat bottom portion of the object prevents the buttons (24, 25) from rising out of said elongated track (11) and said buttons (24, 25) being prevented from sliding along said elongated track (11) by the contact between the pair of opposed semicircular faces (15, 15') of the track groove top (13) and the opposed semicircular sides (30, 31) of said buttons (24, 25) and the securable fitting (17) is prevented from sliding along the elongated groove (12) by contact with the buttons (24, 25).

a securable fitting (17) having a stud portion (18) to which objects to be secured may be attached, a track groove top abutting length (19) below said stud portion (18) having four opposed sides, two of which sides (20, 21) which closely abut a pair of opposed tabs (16, 16'), and each of the remaining two sides (22, 23) closely abut a side of an adjacent button (24, 25), and a bell shaped flared base (26) below said track groove top abutting length (19), said bell shaped flared base (26) being shaped to closely slide in said elongated groove (12) and extending below said opposed tabs (16, 16') and rest on a floor (12') of said elongated groove (12);
a pair of buttons (24, 25) each button having a top surface (28), a side area (29) having a pair of opposed semicircular sides (30, 31), and at least one side portion (32) which abuts one of said remaining two sides of said track groove top abutting length (19) of said securable fitting (17), and each of said buttons (24, 25) having at least one inwardly flared area (33, 34) to permit the positioning of each pair of buttons (24, 25) adjacent a bell shaped flared base (26) of a securable fitting (17) when said pair of buttons (24, 25) are resting on said groove floor (12') of said bell shaped groove (12) whereby when an object with a flat bottom is secured to said stud portion (18) of said securable fitting (17) the flat bottom of the object prevents the buttons (24, 25) from rising out of said elongated track (11) and said buttons (24, 25) being prevented from sliding along said elongated track (11) by the contact between the pair of opposed semicircular faces (15, 15') of the track groove top (13) and the opposed semicircular sides (30, 31) of said buttons (24, 25) and the securable fitting (17) is prevented from sliding along the elongated groove (12) by contact with the buttons (24, 25).
