Abstract
A venetian blind with individually adjustable slats. Each slat has a multilayer decorative slat extensions mounted in a slat extension holder. The individual slat extensions are mounted directly above one another in the unextended position. Each slat can be individually adjusted in length by sliding the slat extensions in opposite directions. The slats in the blind can be extended to allow the blind to be used on windows of varying width. Each slat can be individually adjusted to allow the blind to be used interchangeably on rectangular windows or on odd shaped windows such as arched windows. The cords used to control slat position and the cords used to raise and lower the slats are mounted on the edge of the slats which do not have holes.
Claims20
An adjustable venetian blind, comprising:
- a headrail having a lilt cord drive assembly and a tilt cord drive assembly;
- lift cords attached to the lift cord drive assembly in the headrail;
- tilt cords attached to the tilt cord drive assembly in the headrail, each tilt cord further comprising a front tilt cord, a rear tilt cord and a plurality of cord rungs connecting the front tilt cord and the rear tilt cord;
- and
- a plurality of elongate slats, at least one of which is an independently adjustable slat, each slat comprising:
- an elongate slat extension holder having a front side edge and a rear side edge along opposing longitudinal edges of said slat extension holder, the slat extension holder further having edge grips at both side edges;
- at least two elongate slat extensions, the slat extensions inserted in the slat extension holder one overlapping another and slidably held by the edge grips, each slat extension independently movable in relation to the other slat extension holder such that the width of the slat can be varied independently of other slats in the venetian blind;
- the tilt cords and lift cords extending outside of and adjacent to the side edges of the slats such that each slat rests on at least a pair of cord rungs and neither the tilt cords or the lift cords pass through a slat;
- at least one slat extension holder having means to retain a tilt cord;
- at least on slat extension holder having means to retain a lift cord;
- whereby the width of the independently adjustable slat in the venetian blind can be independently varied from the width of the other slats in the venetian blind.

- comprising a front tilt cord, and a rear tilt cord;
- and
- a plurality of elongate slats, at least one of which is an independently adjustable slat, each slat comprising:
- An elongate slat extension holder having a front side edge and a rear side edge along opposing longitudinal edges of said slat extension holder, the slat extension holder further having edge grips at both side edges;
- at least two elongate slat extensions, the slat extensions inserted in the slat extension holder one overlapping another and slidably held by the edge grips, each slat extension independently movable in relation to the other slat extension holder such that the width of the slat can be varied independently of other slats in the venetian blind;
- the front tilt cords retained by at least one slat extension holder and the rear tilt cords retained by at least one slat extension holder, each slat rests on at least a pair of cord rungs and neither the tilt cords or the lift cords pass through a slat;
- whereby the width of the independently adjustable slat in the venetian blind can be independently varied from the width of the other slats in the venetian blind.
