PURPOSE: High-airtightness sliding window fittings with movable rails are provided to enhance insulation, soundproof and airtightness since there is no gap between a windowsill and a window. CONSTITUTION: High-airtightness sliding window fittings with movable rails comprise a windowsill upper-frame(1), movable rails(3), sealing members(4,4') and a window frame(2). A binder(11) is integrally formed on the bottom of the windowsill upper-frame. The upper end of the window frame is inserted into the movable rails. The movable rail is installed on the binder and is able to move up and down. The sealing member is installed on both sides of the movable rail in a symmetrical structure. The upper and lower ends of the sealing member are respectively supported on the upper frame and the window frame. Sliding members(25,25') are formed integrally with the window frame. Tilt type guides(252,252') are integrally formed on the upper ends of the sliding members. |
