Parrallel sliding systems

A parallel sliding system, comprising:

• a leaf configured to be displaced horizontally from a closed position, in which the leaf closes an opening, into a sliding position, in which the leaf is configured to slide parallel to the opening into an open position exposing the opening,
• at least one rail configured to guide the leaf in the sliding position,
• at least one sealing body, which when the leaf is moved horizontally from the sliding position to the closed position, is configured to be displaced relative to the leaf in a vertical direction to sealingly close a gap between the leaf and a horizontal spar of a frame profile which surrounds a corresponding portion of the leaf in the closed position, and the at least one sealing body forms, when the leaf is in the sliding position, a line contact with the at least one rail,
• at least one guide fixedly connected to the leaf, and configured to use the horizontal movement of the leaf between the closed position and the sliding position to displace the at least one sealing body in the vertical direction, and
• wherein the at least one guide has a receptacle for the at least one sealing body, in which the at least one sealing body is guided relative to the at least one guide along a slide rail inclined relative to a horizontal and positioned vertically above or below the at least one sealing body, wherein the at least one sealing body is guided in the slide rail.

A parallel sliding system, comprising:

• a leaf configured to be displaced horizontally from a closed position, in which the leaf closes an opening, into a sliding position, in which the leaf is configured to slide parallel to the opening into an open position exposing the opening;
• at least one slide which, when the leaf is displaced horizontally from the sliding position back into the closed position, is configured to be displaced relative to the leaf in a vertical direction in order to sealingly close at least one gap between the leaf and a horizontal spar of a frame profile which surrounds a corresponding portion of the leaf in the closed position;
• at least one guide fixedly connected to the leaf, and configured to use the horizontal movement of the leaf between the closed position and the sliding position to displace the at least one slide in the vertical direction, wherein the at least one guide includes a receptacle for the at least one slide, in which the at least one slide is guided relative to the at least one guide along a slide rail inclined relative to a horizontal, the at least one slide being guided in the slide rail;
• and
• at least one rail configured to guide the leaf in the sliding position, the at least one slide forming, when the leaf is in the sliding position, a line contact with the at least one rail,
• wherein the at least one slide and the at least one rail are configured to engage with one another when the leaf is in the closed position via a tongue-and-groove system including a groove formed in the at least one slide and a tongue formed on the at least one rail, the line contact is provided by a relative inclination between at least one pair of walls including a groove wall and a tongue wall opposite the groove wall, and the groove wall is vertically inclined with respect to the tongue wall or the tongue wall is vertically inclined with respect to the groove wall.
