Abstract
Disclosed are methods and an apparatus for mounting and deployment of retractable covering devices, in particular, light control window covering including a lobed head rail to prevent creasing and/or skewing of the window covering when rolled up, the head rail having means for attaching the window covering which insures proper alignment of the window covering. Also included are a bottom rear rail having an antiskewing device which comprises a slidable weight for compensating for skewed roll up; a flip-catch device for preventing wrong-way roll up of the window covering; and a top-catch mechanism for preventing both wrong-way roll up and over rotation in the proper roll up direction.
