Abstract: A built-in blind assembly includes light-transmissive first and second outer panels, a blind unit, a frame unit, a top rail unit, and a cord-driving unit. The first and second outer panels face each other. The blind unit is disposed between the first and second outer panels. The frame unit includes a top frame disposed above the blind unit. The top rail unit includes a top rail seat that is connected to the top frame and that defines a top accommodating cavity having an open side adjacent to the second outer panel, and a top cover that is removably connected to the top rail seat. The cord-driving unit is disposed in the top accommodating cavity, is coupled to the blind unit, and is operable to control operation of the blind unit.

Abstract: A hollow built-in blind includes two glass plates, an annular spacer cooperating with the glass plates to define a receiving space, and a blind disposed in the receiving space and including a lower rail, a plurality of slats, and two pull cords connected to the lower rail. A transmission unit includes a transmission shaft, a winding mechanism disposed on the shaft, and a belt pulley fixed to one end of the shaft. A drive unit is located at one lateral end of the blind and includes a guide wheel spaced apart from the belt pulley, an internal control device operable to move upward and downward in the receiving space, and a timing belt looped over the belt pulley and the guide wheel and having two opposite ends connected to the internal control device to form a closed loop.
