Device for supporting rails

Device for supporting a rail (1) extending in a long direction and located in a railroad track for railborne vehicles, each said rail having a top surface located in a generally horizontal plane of said railroad track, said railroad track comprising a pair of spaced rails having a center therebetween extending in the long direction, said device comprising a support plate (3) positioned on a support bed (6), interengaging profiled surfaces on said support plate (3) and support bed (6) and extending in the long direction of said rails, elastic elements interposed at least in certain regions between said profiled surfaces, said profiled surfaces comprising sets of flanks (4a, 7a, 4b, 7b, 5a, 8a, 5b, 8b) disposed in spaced facing relation and extending in the long direction of said rails, said sets of flanks including at least two sets of first flanks extending at an angle different from 90.degree. with respect to a line perpendicular to the plane containing the top surfaces of said rails, the angle of said at least two sets of first flanks diverging from the perpendicular line in the upward direction towards the center of the railroad track and the angles increasing in angular measurement relative to the center of the said railroad track from inside said rails to outside said rails.
