The support has support units (6) each comprising a base plate (7) and two suspension blocks (8) mounted on helical springs at ends of the base plate. A roller block (9) is suspended between the suspension blocks, and has a pair of bottom rollers (10) that support a glazed sliding door or window to allow sliding of the door or window. The bottom rollers are ball bearings mounted on cylindrical axles (11) fixed and tilted in opposite direction in the roller block for assuring permanent self-centering of the door or window during sliding. An independent claim is also included for a glazed sliding door or window comprising a movable glazed element with frames formed of metal or plastic profiles. |
