Abstract
A TDBU (top down, bottom up) window covering includes a first crossbeam and a second crossbeam below a fixture, wherein a slat assembly is connected between the first crossbeam and the second crossbeam. A first control structure is further provided in the first crossbeam, and a second control structure is provided in the second crossbeam. The first control structure moves the first crossbeam toward or away from the fixture, and the second control structure moves the second crossbeam toward or away from the first crossbeam. Whereby, the assembling and the maintenance of the window covering are more convenient and easier.
