THREE-WHEELED CORD ROLLING DEVICE FOR NON-PULL CORD WINDOW BLIND
A three-wheeled cord rolling device includes a driving unit having two torsion spring wheels engaged with each other and a torsion spring connecting the torsion spring wheels, and a cord rolling unit having a cord rolling wheel and two lift transmission cords. The cord rolling wheel is engaged with one of the torsion spring wheels, thereby rotatable with them synchronously. The cord rolling wheel has an axle having upper and lower axial portions and a separating portion connecting the upper and lower axial portions. The lift transmission cords are disposed on the upper and lower axial portions of the axle respectively, thereby capable of being rolled up or released from the upper and lower axial portions of the axle by the rotation of the cord rolling wheel.
