摘要

A light blocking element is movably coupled to and recessed into one of a first rail and a movable rail, and, when the movable rail moves to a position closest to the first rail, the light-blocking element enters into a recess in the other of said first rail and said movable rail and thereby is recessed into both said first rail and said movable rail.

1. A covering for an architectural opening, comprising:
an elongated first rail extending in a left-to-right direction and defining an elongated bottom-facing opening extending in the left-to-right direction; a movable rail adjacent to said elongated first rail, said movable rail being movable from an uppermost position to a lower position; an extendable covering secured to said movable rail, said extendable covering extending and retracting as said movable rail moves toward and away from said elongated first rail; an elongated light blocking element received in said elongated first rail, said elongated light-blocking element defining front and rear wings located inside said first rail; a central body portion beneath said front and rear wings, said central body portion extending through said bottom-facing opening; and a lower contact portion extending below said central body portion; said light-blocking element being movable from a suspended position at a first elevation, in which said light-blocking element is supported by and suspended from said first rail, with said front and rear wings resting on said first rail, to a raised position at a second elevation, higher than the first elevation, in which said lower contact portion of said light-blocking element rests on said movable rail so that said movable rail supports said light blocking element.
