Abstract

See full text

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 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. The cord is secured to and is wound about a spool fixed to a spring-loaded roller. The roller provides tension on the cord that counterbalances the weight of the shade so that the shading material may be positioned at any desired level. The shade does not require a graspable cord or cords for operation.
