Bottom rail structural configuration for a venetian blind

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.
