摘要

A covering (100) for an architectural opening is provided. The covering (100) may include a rotatable outer tube (150), a rotatable inner tube (140), a shade (106) attached to the outer tube (150), and an operating element (108) secured to the inner tube (140). The outer tube (150) may define an elongated slot (160) extending along a length of the outer tube (150) and opening to an interior of the outer tube (150). The inner tube (140) may be received within the outer tube (150). The shade (106) may be retractable to and extendable from the outer tube (150). The operating element (108) may extend through the elongated slot (160) and may be retractable onto and extendable from the inner tube (140). The inner tube (140) may rotate relative the outer tube (150) to open and close the shade (106) once the support sheet (114) is in a fully extended position. 4846-3620-5356/2 Cl~ 3 /32 LCC) coo m000 C~o0 'IO.
