Abstract

A window apparatus includes a window framework, a shading device and a control device. The window framework comprises a first pair of parallel frames, a second pair of parallel frames which are perpendicularly mounted between the first pair of parallel frames defining a window framework, and a pair of transparent boards which are mounted on the window framework in parallel manner to define a receiving chamber therebetween. The shading device comprises a plurality of slats and a supporting device for mounting the slats parallelly inside the receiving chamber, i.e. between the pair of transparent boards. The control device which is incorporated with the supporting device for adjusting various displacing angles of the slats, gathering the slats toward a side of the window frame, and distributing the slats over the receiving chamber. Thereby, the window apparatus having a built in shading device installed within dual sheets of glass can provide a more efficient way of shading and the blocking of light and a more efficient way of insulating temperature and provide the resistance of sound entering and leaving the environment surroundings.
