A handicapped accessible seat that classifies functionally as an aircraft seat is configured for maneuvering within an aircraft and docking to an aircraft floor using a typical track member having a longitudinal flange like extension and counterbores for mating with a shear plug of an aircraft seat.
A handicapped accessible seat that classifies functionally as an aircraft seat is configured for maneuvering within an aircraft and docking to an aircraft floor using a typical track member having a longitudinal flange like extension and counterbores for mating with a shear plug of an aircraft seat. A bracket or track above the typical track member and containing inwardly-extending longitudinal flanges allows mating association with a plug or plunger on the wheel/caster or bottom seat structure of the handicapped accessible seat (94). A flange-like extension along the bottom portion of the track, having a planar portion along the floor of the aircraft and an outer, upward portion, could run the entire length of an aircraft or in only specific portions thereof and may also be used to guide the wheels into a locking position.

1. A system for selectively securing and removing a wheelchair-bound individual to an aircraft, comprising: a wheelchair having a seat supported by a lower frame, said lower frame supported by rotatable rolling means that enable said wheelchair to be maneuvered from place to place within the aircraft with said individual in the seat,an elongated track assembly secured to the floor of said aircraft, said track assembly having rigid opposing sides defining a longitudinally extending open guideway therebetween and a pair of rigid retainer flanges overlying said guideway and arranged in spaced edge to edge relation to each other and defining an elongate keyway therebetween; andlocking means on said wheelchair operatively arranged to lock said wheelchair to said track assembly, said locking means located within said rotatable rolling means, being selectively lockable by only the foot of a user, and comprising a locking pin sized to fit within said elongate keyway of the guideway, the locking means being engaged within the guideway to prevent movement of the wheelchair relative to said track. 2. The system of claim 1 wherein said wheelchair is configured to resemble surrounding aircraft seats and comprises a flotation cushion and seatbelt. 3. The system of claim 1 wherein said locking pin is constructed to engage firmly against the bottom of the track. 4. The system of claim 1 wherein said locking means comprises a compression spring anchored against said wheelchair and bearing downwardly on said locking pin. 5. The system of claim 1 wherein the flanges have a plurality of pairs of recesses in the edges thereof at regularly spaced intervals along the track, each pair of recesses being located directly opposite each other and cooperatively defining an enlarged access opening into the guideway, wherein said locking pin is sized to fit through said enlarged access opening into the guideway and can be removably inserted into one of the access openings of the guideway to prevent movement of the wheelchair relative to said track, and wherein said access opening in the track and said locking pin have complementary shapes for tight fitting therebetween. 6. The system of claim 5 wherein said track assembly further comprises a longitudinally extending upper keyway situated above said elongate guideway, said upper keyway defined by a pair of rigid opposing sides and at least partially overlaid by a pair of rigid retainer flanges arranged in spaced edge to edge relation to each other. 7. The system of claim 6 wherein said locking means is configured to allow said locking pin to lock within said upper keyway of said track assembly. 8. The system of claim 6 wherein said locking pin comprises an enlarged head being of dimensions larger than said access openings of the guideway to prevent insertion therein. 9. In combination, a wheelchair having a seat supported by a lower frame and rotatable rolling means that enable said wheelchair to be maneuvered from place to place within the aircraft, said wheelchair configured to resemble an aircraft seat and comprising a flotation cushion and seatbelt;an assembly for securing said wheelchair to an aircraft, comprising: an elongated track assembly secured to the floor of an aircraft, said track assembly having rigid opposing sides defining a longitudinally extending open guideway therebetween and a pair of rigid retainer flanges overlying said guideway and arranged in spaced edge to edge relation to each other; andlocking means on said wheelchair operatively arranged to lock said wheelchair to said track assembly, said locking means being located within said rotatable rolling means, being selectively lockable by only the foot of a user, and comprising a locking pin sized to fit within said elongate keyway of the guideway, the locking means being engaged within the guideway to prevent movement of the wheelchair relative to said track. 10. The combination of claim 9 wherein said locking pin is constructed to engage firmly against the bottom of the track. 11. The combination of claim 9 wherein said locking means comprises a compression spring anchored against said wheelchair and bearing downwardly on said locking pin. 12. The combination of claim 9 wherein the flanges have a plurality of pairs of recesses in the edges thereof at regularly spaced intervals along the track, each pair of recesses being located directly opposite each other and cooperatively defining an enlarged access opening into the guideway, wherein said locking pin is sized to fit through said enlarged access opening into the guideway and can be removably inserted into one of the access openings of the guideway to prevent movement of the wheelchair relative to said track, and wherein said access opening in the track and said locking pin have complementary shapes for tight fitting therebetween. 13. A wheelchair capable of being secured within an aircraft, said aircraft having an elongated track assembly secured to the floor thereof, said track assembly having rigid opposing sides defining a longitudinally extending open guideway therebetween and a pair of rigid retainer flanges overlying said guideway and arranged in spaced edge to edge relation to each other, said wheelchair comprising: a seat supported by a lower frame,rotatable rolling means that enable said wheelchair to be maneuvered from place to place within the aircraft,said wheelchair being configured to resemble a standard aircraft seat and comprising a flotation cushion and seatbelt; andlocking means located within said rotatable rolling means and operatively arranged to selectively lock said wheelchair to said track assembly using only the foot of a user, said locking means comprising a locking pin sized to be locked within said guideway of said track assembly to prevent movement of the wheelchair relative to said track. 14. The wheelchair of claim 13 wherein said locking means is constructed to engage firmly against the bottom of the track. 15. The wheelchair of claim 13 wherein said locking means comprises a compression spring anchored against said wheelchair and bearing downwardly on said locking pin. 16. The wheelchair of claim 13, wherein the flanges of said track assembly have a plurality of pairs of recesses in the edges thereof at regularly spaced intervals therealong, each pair of recesses being located directly opposite each other and cooperatively defining an enlarged access opening into the guideway, wherein said locking means further comprises a head at an end of said locking pin that is sized to fit through said enlarged access opening into the guideway and can be removably inserted into one of the access openings of the guideway to prevent movement of the wheelchair relative to said track. 17. The wheelchair of claim 16, wherein said head has a shape complementary to that of said access opening in the track for tight fitting therebetween. 18. The wheelchair of claim 16, wherein said track assembly further comprises a longitudinally extending upper keyway situated above said elongate guideway, said upper keyway defined by a pair of rigid opposing sides and at least partially overlaid by a pair of rigid retainer flanges arranged in spaced edge to edge relation to each other, wherein said locking means is configured to allow said locking pin to lock within said upper keyway of said track assembly.
