ABSTRACT:
An improvement in a Venetian blind comprises a bottom rail in openable box form containing means for permitting easy adjustment of the length of the lift cords and slat ladders of the blind, and therefore the overall length of the blind, to adapt it to different window lengths. Preferably, the box comprises a horizontal lower bottom portion with closed bottom and upraised sloped sides and a horizontal upper portion with closed top and depending sloped sides, the latter usually fitting closely between the upraised sides. The two portions are releasably held together, as by removable pins extending therethrough. The lower edges of the depending sides can define inverted V-shaped keeper slots or the like to releasably retain the vertical string portions of the ladders. The upper portion may have apertures in the top down through which the lift cords pass. Knots can be repositioned in the ends of the lift cords and the vertical string portions to releasably and adjustably retain the lift cord and ladder ends within the bottom rail.
