Description

橫拉窗及橫拉窗之下框Horizontal sash windows and the lower frame of horizontal sash windows

本發明係與橫拉窗有關；特別是指一種能洩壓排水之橫拉窗及橫拉窗之下框。The present invention is related to horizontal sash windows; in particular, it refers to a horizontal sash window and the lower frame of the horizontal sash window capable of releasing pressure and draining water.

已知橫拉窗由於操作簡單且其窗扇開啟時占用的空間較平開門窗小，因此，橫拉窗已普遍的被使用者所採用。橫拉窗一般包含有窗框及兩窗扇，其窗框上設置有二相互平行的軌道，分別提供兩窗扇錯開地且可相對平移地與之結合，其操作方式是藉由推拉兩窗扇，使兩窗扇在窗框上的軌道上橫移，如此一來，能透過兩窗扇與窗框彼此之間的密封以防止室外側的風和雨水注入室內側的空間。It is known that horizontal sash windows have been widely adopted by users because of their simple operation and less space occupied when the sash is opened than that of casement doors and windows. Horizontal sash windows generally include a window frame and two window sashes. The window frame is provided with two mutually parallel rails, respectively providing two window sashes that are staggered and can be relatively translationally combined with them. The operation method is to push and pull the two window sashes to make The two sashes move laterally on the track on the window frame, so that the air and rainwater from the outside can be prevented from being injected into the space on the inside of the room through the sealing between the two sashes and the window frame.

然而，當風雨過大時，容易造成室外側之壓力大於室內側之壓力而形成一壓力差，該壓力差容易使得風雨經由窗框及兩窗扇間或是兩窗扇之間的縫隙而滲入室內側空間，舉例來說，當兩窗扇位於封閉窗框之窗口的位置時，兩窗扇交疊處的底部與窗框之間的交接處容易因為無法完全阻擋因風壓所造成的風雨滲入，而使風雨經由縫隙而滲入室内或被強力的風壓吹濺入室内，而有導致室內潮濕、漏水的問題，故習用之橫拉窗之設計仍有待改善。However, when the wind and rain are too strong, the pressure on the outdoor side is likely to be greater than the pressure on the indoor side, resulting in a pressure difference. The pressure difference is likely to cause wind and rain to penetrate into the indoor side space through the gap between the window frame and the two sashes or between the two sashes. For example, when the two sashes are located at the position of the window that closes the window frame, the junction between the bottom of the overlap of the two sashes and the window frame is prone to cause wind and rain because it cannot completely block the infiltration of wind and rain caused by wind pressure. It penetrates into the room through the gap or is splashed into the room by the strong wind pressure, which leads to the problem of humidity and water leakage in the room. Therefore, the design of the conventional horizontal sash window still needs to be improved.

有鑑於此，本發明之目的在於提供一種橫拉窗，能提供排水洩壓之效果。In view of this, the purpose of the present invention is to provide a horizontal sash window, which can provide the effect of drainage and pressure relief.
