WINDOW COVERING ADJUSTMENT APPARATUS AND METHOD

摘要

A method of controlling the vertical height of a window shade having a top and bottom, which includes providing shade upper support structure at or proximate the shade top; providing at least one substantially vertically elongated shade support line extending downwardly from the upper support structure, and providing shade lower support structure at or proximate the shade bottom; elevating or lowering the shade lower support structure relative to one or more support lines; and securing the shade lower support structure to the line or lines at a selected height position relative to the line length above the lower support structure, whereby the height of the shade bottom can be quickly manually adjusted by adjustment of the height of the shade lower support structure effective securement to line or lines.
