The present invention is directed to a stepless sliding doors system, comprising: two sliding doors (10), at least one of them comprising: two vertical poles (30)； means (50) for rotating each of the vertical poles (30)； to each side of the vertical poles (30) is firmly connected a hand-connector (36)； each of the hand-connectors (36) is pivotally connected to a rail-cart (18) having two rollers (42)； each of the rail-carts (18) comprises a horizontal hinge (58) disposed between the rollers (42), and a vertical springy hinge (70), 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.
