Sliding door device for guiding at least one sliding door, which is arranged between a ceiling surface and a bottom surface, in an opening movement and in a closing movement at least substantially counter to the opening movement, and for holding the sliding door in a closure position, which abuts on a main surface that is arranged perpendicularly to the ceiling surface and/or to the bottom surface and which is at least substantially flush-mounted with the main surface, and in an opening position, which is at least substantially parallel to the main surface and is, in a direction that is perpendicular to the main surface, situated at least partly before the main surface, wherein the ceiling surface is the surface of a ceiling of a space in a region of a door opening and wherein the bottom surface is the surface of a bottom of a space in a region of a door opening, with at least two ceiling-side door fittings (30', 30"), each comprising at least one carriage (32, 32a) and at least one door holder (34, 34a) for holding the sliding door at its edge facing toward the ceiling surface, and with at least two bottom-side door fittings (40', 40"), each comprising at least one carriage (32, 32a) and at least one door holder (34, 34a) for holding the sliding door at its edge facing towards the bottom surface, wherein the door holders (34, 34a) are supported on the respective carriages (32, 32a) in such a way that they are movable, with a movement component which is perpendicular to the main surface, in a displacement direction (44, 44a) that is parallel to the ceiling surface and/or to the bottom surface, and wherein at least part of the door fittings (30', 30", 40', 40") respectively comprises at least one reset element (46, 46a), which is configured to exert, between the respective carriage (32, 32a) and the respective door holder (34, 34a) of the respective door fitting (30', 30", 40', 40"), a reset force (48, 48a) that is counter to a displacement in the displacement direction (44, 44a), from the closure position into the opening position, characterised in that an edge of the sliding door that is oriented in the direction of the opening movement and an edge of the main surface that is adjacent to said edge comprise slide elements, which are configured to come into contact with the neighbouring sliding door, respectively the adjacent main surface, for the purpose of creating a spacing apart of the sliding door and the main surface in the displacement direction (44, 44a), at least during an opening movement and a closing movement. for guiding at least one sliding door, which is arranged between a ceiling surface and a bottom surface, in an opening movement and in a closing movement at least substantially counter to the opening movement, and for holding the sliding door in a closure position, which abuts on a main surface that is arranged perpendicularly to the ceiling surface and/or to the bottom surface and which is at least substantially flush-mounted with the main surface, and in an opening position, which is at least substantially parallel to the main surface and is, in a direction that is perpendicular to the main surface, situated at least partly before the main surface, wherein the door holders (34, 34a) are supported on the respective carriages (32, 32a) in such a way that they are movable, with a movement component which is perpendicular to the main surface, in a displacement direction (44, 44a) that is parallel to the ceiling surface and/or to the bottom surface, and wherein at least part of the door fittings (30', 30", 40', 40") respectively comprises at least one reset element (46, 46a), which is configured to exert, between the respective carriage (32, 32a) and the respective door holder (34, 34a) of the respective door fitting (30', 30", 40', 40"), a reset force (48, 48a) that is counter to a displacement in the displacement direction (44, 44a), from the closure position into the opening position, characterised in that an edge of the sliding door that is oriented in the direction of the opening movement and an edge of the main surface that is adjacent to said edge comprise slide elements, which are configured to come into contact with the neighbouring sliding door, respectively the adjacent main surface, for the purpose of creating a spacing apart of the sliding door and the main surface in the displacement direction (44, 44a), at least during an opening movement and a closing movement.
