A floor track fitting for securing seating or other equipment to a section of aircraft floor track consists of a pair of substantially U-shaped cleat members and a captive bolt. The cleat members are inserted back-to-back through the holes in the floor track. Once the cleat members are in place, a cover is placed over the cleat members so that the captive bolt passes through the top of the cover. The inside of the cover has a pair of integral spaces that force the cleat members outward against the sides of the track channel holes so that the undercut portion of the cleat members locks onto the underside of the floor track. As the bolt is tightened it presses down on the cover and simultaneously draws the cleat members upward against the underside of the floor track to clamp the floor track firmly between the cleat members and the cover.

What is claimed is: 1. Apparatus for securing a piece of equipment to a section of aircraft floor track located on an aircraft floor, the floor track having an upper surface, a lower surface, and a plurality of holes extending through said floor track at regularly-spaced intervals along a longitudinal axis of the floor track, said apparatus comprising: a first substantially U-shaped cleat member comprising a bridge portion and pair of parallel spaced apart leg members, each of said parallel spaced apart leg members comprising a shank portion and a jaw portion, each of said shank portions having an inward facing surface and a substantially semi-cylindrical outward facing surface, each of said shank portions further comprising a fixed end and a free end, said jaw portions each comprising a lip extending radially outward from said semi-cylindrical outward facing surface of said shank portions; a second substantially U-shaped cleat member comprising a bridge portion and pair of parallel spaced apart leg members, each of said parallel spaced apart leg members comprising a shank portion and a jaw portion, each of said shank portions having an inward facing surface and a substantially semi-cylindrical outward facing surface, each of said shank portions further comprising a fixed end and a free end, said jaw portions each comprising a lip extending radially outward from said semi-cylindrical outward facing surface of said shank portions, said first and second cleat members capable of being positioned such that the inward facing surfaces of the shank portions of said first cleat member are parallel and spaced apart from the inward facing surfaces of the shank portions of said second cleat member, said inward facing surfaces defining a space therebetween; and a wedge member, said wedge member comprising a flange adapted to be inserted in the space between the inward facing surfaces of the shank portions of said first and second cleat members for forcing said cleat members outward against said floor track. 2. The apparatus of claim 1, wherein: said bridge portion of said first and second substantially U-shaped cleat members each further comprise an inward facing surface, said inward facing surfaces cooperating to form an aperture for accepting a threaded fastener. 3. The apparatus of claim 2, further comprising: a threaded fastener passing through said aperture. 4. The apparatus of claim 3, wherein: said wedge member further comprises a platform member having an aperture sized to permit said threaded fastener to pass therethrough, said wedge member further comprising a strut member extending downward from said platform member, said strut member having a lower surface capable of bearing on one of said floor track and said aircraft floor, whereby as said threaded fastener is tightened against said platform member, said first and second substantially U-shaped cleat members are drawn upward against said floor track as said wedge member is draw downward against said floor track. 5. The apparatus of claim 1, wherein: each of said plurality of holes in said aircraft floor track are circular and of substantially the same radius and wherein the radius of the semi-cylindrical outward facing surfaces of said shank portions are substantially equal in radius to the radius of said plurality of holes. 6. The apparatus of claim 1, further comprising: an aircraft seat, said aircraft seat having a lower flange, said lower flange attached to said aperture by a nut threaded onto said threaded fastener. 7. Apparatus for securing a piece of equipment to a section of aircraft floor track, the floor track having an upper surface, a lower surface, and a plurality of holes extending through said floor track at regularly-spaced intervals along a longitudinal axis of the floor track, said apparatus comprising: a first leg member comprising a first downwardly extending shank defining a lower end and an upper end, said first downwardly extending shank further comprising a first outward facing lateral surface and a first inward facing lateral surface said first leg member further comprising a first jaw member extending outward from said first outward facing lateral surface proximal the lower end of said first downwardly extending shank; a second leg member comprising a second downwardly extending shank defining a lower end and an upper end, said second downwardly extending shank further comprising a second outward facing lateral surface and a second inward facing lateral surface, said second leg member further comprising a second jaw member extending outward from said second outward facing lateral surface proximal the lower end of said second downwardly extending shank; a first bridge member connecting said upper end of said first leg member to said upper end of said second leg member; a third leg member comprising a third downwardly extending shank defining a lower end and an upper end, said third downwardly extending shank further comprising a third outward facing lateral surface and a third inward facing lateral surface said third leg member further comprising a third jaw member extending outward from said third outward facing lateral surface proximal the lower end of said third downwardly extending shank, said third leg member adapted to be positioned such that said third inward facing surface is parallel and spaced apart from said first inward facing surface defining a first gap therebetween; a fourth leg member comprising a fourth downwardly extending shank defining a lower end and an upper end, said fourth downwardly extending shank further comprising a fourth outward facing lateral surface and a fourth inward facing lateral surface said fourth leg member further comprising a fourth jaw member extending outward from said fourth outward facing lateral surface proximal the lower end of said fourth downwardly extending shank, said fourth leg member adapted to be positioned such that said fourth inward facing surface is parallel and spaced apart from said second inward facing surface defining a second gap therebetween; a second bridge member connecting said upper end of said third leg member to said upper end of said fourth leg member; a wedge member, said wedge member comprising a flange adapted to be inserted in said first gap for forcing said first and third leg members outward against said floor track. 8. The apparatus of claim 7, wherein: said wedge member further comprises a second flange adapted to be inserted in said second gap for forcing said second and fourth leg members outward against said floor track. 9. The apparatus of claim 7, wherein: said first bridge member comprises an inward facing surface, said inward facing surface having a depression therein and said second bridge member comprises a cantilever member having an aperture therethrough, said aperture and said depression cooperating to capture a threaded fastener therebetween. 10. The apparatus of claim 9, further comprising: a threaded fastener passing through said aperture. 11. The apparatus of claim 7, wherein: said wedge member further comprises a platform member having an aperture sized to permit said threaded fastener to pass therethrough, said wedge member further comprising a strut member extending downward from said platform member, said strut member having a lower surface capable of bearing on said floor. 12. The apparatus of claim 11, further comprising: an aircraft seat, said aircraft seat having a lower flange, said lower flange having an aperture sized to permit said threaded fastener to pass therethrough, and a nut member threaded onto said threaded fastener, whereby as said nut member is tightened on said threaded fastener, said lower flange bears on said platform member and said jaw members are drawn upward against said floor track as said wedge member is draw downward against said floor track capturing said floor track therebetween.
