ABSTRACT:
In all three versions, the bottom rail has a flat, smooth bottom and does not tilt. In two versions, transverse horizontal holes receive ladder cords. In one of these versions, another horizontal hole opening at the rear of the rail extends obliquely into intersection with the transverse hole midway between the front and rear of the rail. A vertical hole extends down from the rail top to this intersection. A lift cord extends down through the vertical hole into the oblique hole where a knot on the lift cord fixes the end of the cord in the oblique hole. In too the other of these two versions, a horizontal transverse hole above each ladder cord hole receives a lift cord which extends out at the front and rear of the bottom rail. These lift cords, and the ladder cords, extend entirely up to the headrail. In this version, each slat has a notch at the front edge and rear edge, receiving the corresponding lift cord and ladder cord. These notches are small so when the blind is closed, they are covered by the next adjacent slat. A supplemental slat under the bottom slat has deeper notches so when the blind is closed, the supplemental slat descends, unlimited by the slat support strands, into gap closing contact with the bottom rail. The third version has notched slats but decorative ladder tapes are fastened to the front and rear faces of the bottom rail and hide the lift cords.
