SHIFTING WEIGHT BOTTOM RAIL

摘要

A covering for an architectural opening is made for better closure, especial ly adjacent to the bottom rail. A movable weight is mounted on the bottom rail, so that the weight shifts to the lower side of the bottom rail when the bottom rail is tilted. A lift cord is mounted to support the bottom rail while being freely movable relative to th e bottom rail at least in the front-to-back direction. The weight helps shift the bottom rail into the desired position, and, by being freely movable in the front-to-back directio n, the lift cord does not interfere with the motion of the bottom rail.
