  • Publication number: 20240117671
    Abstract: A cordless window covering includes a first rail, a second rail, a covering body, two pulling cords, and a cord-retracting device including a first casing and an adjusting member movably disposed on the first casing. When relative motion of the first rail and the second rail occurs, the covering body is extended or retracted, and the two pulling cords apply a first force and a second force in opposite directions to the adjusting member respectively. When the first force does not equal to the second force, the user can exert slight force on the second rail to move the adjusting member towards a side with greater force, making one of the pulling cords applying greater force to the adjusting member have its length between the first rail and the second rail elongate as the adjusting member moves, such that the non-horizontal state of the second rail can be easily corrected.
