The present invention is directed to a stepless sliding doors system, comprising: two sliding doors (), at least one of them comprising: two vertical poles (); means () for rotating each of the vertical poles (); to each side of the vertical poles () is firmly connected a hand-connector (); each of the hand-connectors () is pivotally connected to a rail-cart () having two rollers (); each of the rail-carts () comprises a horizontal hinge () disposed between the rollers (), and a vertical springy hinge (), for applying pulling or pushing force of the rollers on a rail thereof, thereby allowing placing the sliding doors of the system in the same plane when in the closed state of the doors, and shifting the doors one along the other in the open state thereof, and additionally preventing the wheels to deviate from a rail in the case of slight deformations. 1. A stepless sliding door system , comprising:{'b': 10', '10', '16, 'i': a', 'b, 'claim-text': [{'b': '46', 'a chassis () connected to said sliding door;'}, {'b': '30', 'two vertical rotatable poles ();'}, {'b': '18', 'two pairs of rail-carts ();'}, {'b': 36', '36', '30', '18, 'i': a', 'b, 'two pairs of hand-connectors (, ), each of the hand-connectors firmly connected in one end thereof to one of said vertical rotatable poles (), and pivotally connected in the other end thereof to one of said rail-carts ();'}, {'b': 72', '72', '50', '30', '30', '50, 'i': a', 'b, 'two spiral rotation assemblies (, ), each comprising a vertically shiftable tube () in which one of said vertical rotatable poles () is disposed, for rotating each of said vertical poles () by 90 degrees upon shifting said vertically shiftable tube (); and'}, {'b': 60', '54', '50', '72', '72', '50, 'i': a', 'b, 'a transverse rod (, ), connecting the vertically shiftable tube () of each of said spiral rotation assemblies (, ), for allowing simultaneous shifting of the vertically shiftable tube ();'}], 'two sliding doors (, ) disposed in a closed state ...
