Abstract:
A window shade that reduces the risk of an individual becoming entangled in cords used to operate the shade includes a headrail adapted for horizontal mounting above a window, a shading material attached to the headrail, and at least one cord for raising and lowering the shading material. The cord is attached to a location adjacent a lower end of the material, and extends upward through split ring cord guides toward the headrail. The cord is encased within a collapsible shroud attached to each cord guide. The shroud is adapted to longitudinally extend as the shading material is lowered toward a deployed position, and then longitudinally collapse as the shading material is raised toward a stowed position.
