发明名称 Cordless roman shade
摘要 A cordless Roman shade includes a head rail internally provided with a tension lifting mechanism for providing a balancing force or a tension force; a shade connected at an upper portion to the head rail and including a plurality of horizontal cells; a plurality of lines associated with the shade and controlled by the tension lifting mechanism to rewind or release, so as to lift or lower the shade to a desired height; and at least one bracing system mounted on the lowest cell of the shade to stretch open and thereby stiffen the lowest cell. A user may apply an upward or downward force at the stiffened lowest cell to lift or lower the shade.
