发明名称 STRUCTURE OF CURTAIN
摘要 A structure of a curtain includes a main curtain body having a beam, a curtain sheet with an end coupled to the beam, and transversal rods installed onto the curtain sheet, first latches installed separately at another end of the curtain sheet, second latches installed separately onto each transversal rod, an ascending/descending unit coupled to the main curtain body and including a winding/unwinding shaft on a side of the beam, a pull string with an end coupled to the first latch, passed through the second latch, and connected to the winding/unwinding shaft, and a chain for transmitting the winding/unwinding shaft, and a third latch installed onto the chain. If a too-large force is applied to the pull string or chain, the first, second and third latches will be separated to prevent the pull string or chain from being wound around a human body and achieve a higher safety effect.
