Abstract
An apparatus for accumulating one or more lift cords used to lift an architectural opening covering comprises a base portion and a front portion having a diameter larger than a diameter of the base portion. The base portion has an opening configured to receive a rod that rotates in a first direction when the one or more lift cords are actuated to raise the architectural opening covering. The apparatus also comprises an outer surface having a plurality of grooves configured to receive at least one of the one or more lift cords when the one or more lift cords are actuated to raise the architectural opening covering and to allow the at least one of the one or more lift cords to accumulate on one or more of the plurality of grooves next to itself rather than on top of itself.
