Blind cord spool structure
A blind cord spool structure has a cord spool. The cord spool includes a bottom case, force-receiving wheel, driven chainwheel, top case, two rotatable units, and two spool rollers. The bottom case is in long rectangular shape. The bottom case and the top case allow the force-receiving wheel, driven chainwheel, rotatable units and spool rollers to be fitted together. The force-receiving wheel meshes with the driven chainwheel through a plurality of planetary gears and interlocks with the spool rollers and rotatable units through a driven gear. The high speed reduction ratio of the planetary gears effectively reduces the required weight of a volute spiral spring and reduces the operation cost of the volute spiral spring. With the bottom case being in long rectangular shape, the force-receiving wheel, rotatable units and spool rollers can be collectively mounted on the same standard surface, allowing the cord spool to be structurally simple.

Cordless window covering
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.
