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.

In a Venetian blind having: (a) a plurality of thin horizontally disposed slats; (b) a horizontal head rail above and a horizontal bottom rail below said slats; (c) a plurality of horizontally spaced flexible string ladders connected between said head rail and said bottom rail for holding said slats in vertically spaced relation, one above another between said rails; and (d) a plurality of lift cords extending from said head rail and connected to said bottom rail for movement of said bottom rail, ladders and slats toward and away from said head rail; the improvement which comprises: a bottom rail which is an openable box and which contains holding means for individually adjusting the effective lengths of said lift cords and ladder strings, said holding means being concealed from view when the box is closed; and releasable means for maintaining the box in a closed position, said releasable means being invisible from the front side of the blind; the bottom rail further comprising: (e) a generally horizontally extending lower member having a closed bottom and upraised sides; and (f) a generally horizontally extending upper member with closed top and depending sides; wherein a plurality of spaced transverse pins releasably extend through aligned openings in said depending sides of the upper member and the upraised rear side of the lower member and into openings in the upraised front side of the lower member which do not extend entirely through said front side, thereby leaving the front face of the bottom rail unblemished.
