摘要：
A hold down device is provided for continuous loop cords or bead chains in a window covering installation. The hold down device engages the cord or chain while the cord or chain is loosely suspended, and prevents operation by encountering the head rail if the cord or chain is operated. Mounting the hold down device in a window covering installation disengages the hold down device from its secured position relative to the cord or chain.
