ABSTRACT:
A window blind cord winding apparatus includes an outer housing with a circular spool receiving cavity. A spool is provided that has a circular cord bell receiving cavity. The spool is disposed within the circular spool receiving cavity of the outer housing. The circular cord bell receiving cavity has an inner surface with a gear profile. A closure cap is engagable with the outer sidewall to enclose the outer housing. The closure cap has an exterior surface and an interior cavity. A shaft extends through the closure cap. The shaft has a first end extending into the interior cavity and a second end extending from the exterior surface. A gear is mounted to the first end of the shaft. A hand grip is secured to the second end of the shaft. When the closure cap is placed onto the outer housing the gear engages the gear profile on the inner surface of the cord bell receiving cavity of the spool. Upon the hand grip being used to rotate the shaft, the gear rotates engaging the gear profile to rotate the spool. A locking mechanism is provided for locking the spool in a selected rotational position relative to the outer housing.
