Casement Windows: The Top Half Pushes Out and Stays

A set of支摘窗 (zhizhaichuang, prop-and-lift windows). The window is divided into upper and lower sections: the upper section can be pushed outwards and propped open with a slender support rod, creating an outward-sloping angle for sun shading and ventilation; the lower section is a fixed panel that can be entirely removed. Currently, the upper section is pushed open about forty-five degrees, with the end of the support rod inserted into a groove in the window frame; light streams in diagonally through the opening, forming a distinct long strip of light on the indoor floor. The window's openwork infill consists of fine lattice strips forming a regular pattern, backed with translucent paper. The wood is dark. Looking out from indoors, a part of the courtyard can be seen. Avoid: making the window into modern sliding or casement forms, omitting the support rod so the opening method is unclear, using clear glass, or making the upper and lower sections integrated and inseparable.

一組支摘窗。窗分成上下兩段:上段可以向外推開並以一根細長的支桿撐住,形成一個向外斜出的遮陽兼通風的角度;下段是可以整片摘下的固定扇。此刻上段被推開約四十五度,支桿的末端插在窗框的凹槽中;光從開啟的縫隙斜射進來,在室內的地面形成一道明確的長條光斑。窗的格心是細櫺條組成的規則圖案,糊著半透明的紙。木料是深色的。從室內看出去,可以看見庭院的一部分。避免:把窗做成現代的推拉與平開形式、省略支桿讓開啟的方式看不出來、使用清玻璃、把上下兩段做成一體不可分。
