Description

Technical Field

[0001] The utility model relates to the technical field of door and window structures, and more specifically, to a double-sash casement window. Background Art

[0002] Windows are the most common structures in buildings and serve as ventilation and daylighting openings for rooms in buildings. Currently, the popular opening method of windows is the casement window. Most of the existing inner-opening casement window screens are fixed to the window frame, unable to be opened, and are inconvenient for disassembly and cleaning.

[0003] Chinese Utility Model Patent with Publication No. CN206874141U discloses a broken-bridge heat-insulating screen integrated casement window, which includes a window frame, a casement window sash, a mullion, a fixed window sash, and a transom. The casement window sash is installed in the window frame through hinges. On the relative outdoor position of the casement window sash, there is also a screen frame and a screen sash. The screen frame is fixed inside the window frame, and the screen sash is installed in the screen frame through small hinges. Both the casement window sash and the screen sash face the interior of the room.

[0004] In the above screen integrated casement window, the screen frame and the screen sash are installed on the casement window sash. Since the sealing flange provided on the outer side of the window frame is higher than the highest point of the equal pressure rubber strip, when rainwater enters the gap between the casement window sash and the window frame, the rainwater may overflow on the window frame and enter the room, resulting in water seepage of the doors and windows.
