Abstract

A shade covering for a blind having a plurality of horizontal slats and at least one cord ladder configured to support the slats may generally include a plurality of attachment portions configured to be spaced apart from one another along a first direction of the shade covering. Each attachment portion may define an insertion slit. The shade covering may also include a plurality of shade portions extending between each adjacent pair of attachment portions. Moreover, the insertion slit may be defined through a rear end of each attachment portion such that an insertion end of the insertion slit is open at the rear end.

First claim

What is claimed is:

1. A blind assembly for an architectural opening, the blind assembly comprising:
a blind including a plurality of slats and at least one cord ladder configured to support said slats, said at least one cord ladder including a front ladder run, a rear ladder run, and a plurality of support rungs extending between said front and rear ladder runs, said front ladder run extending along a front side of said blind and said rear ladder run extending along a rear side of said blind; and
a separate shade covering configured to be secured to said blind such that said shade covering extends along said front side of said blind, said shade covering including a plurality of attachment portions and a plurality of shade portions, each said attachment portion defining an insertion slit and an attachment slit, each shade portion being configured to extend between adjacent pairs of said attachment portions;
wherein:
said insertion slit is defined through a rear end of each said attachment portion such that an insertion end of said insertion slit is open at said rear end; and
said attachment slit extends outwardly from said insertions slit at a location spaced apart from said rear end.

2. The blind assembly of claim 1 , wherein said shade covering is installed onto said blind by moving said shade covering relative to said blind in a first direction from said front side of said blind to said rear side of said blind such that said font ladder run is received within said insertion slit at said insertion end.

3. The blind assembly of claim 1 , wherein said attachment slit terminates at an attachment opening, said attachment opening having a larger crosswise dimension than said attachment slit.

4. The blind assembly of claim 1 , wherein said attachment slit is configured to receive said front ladder run.

5. The blind assembly of claim 4 , further comprising:
a lift cord extending through each of said slats at a location adjacent to said at least one cord ladder,
wherein:
each said attachment portion further defines a second attachment slit extending outwardly from said insertion slit and being spaced apart from said attachment slit; and
said second attachment slit is configured to receive said lift cord.

6. The blind assembly of claim 1 , wherein each said attachment portion is configured to be coupled to said corresponding slat to secure said shade covering to said blind.

7. The blind assembly of claim 1 , wherein each said attachment portion and each said shade portion is formed from a separate web.

8. The blind assembly of claim 1 , wherein said attachment portions and said shade portions are formed from a continuous web.

9. The blind assembly of claim 1 , wherein each said shade portion includes a crease line, a lower wall segment extending between said crease line and a lower attachment portion of each of said adjacent pairs of said attachment portions, and an upper wall segment extending between said crease line and an upper attachment portion of each of said adjacent pairs of said attachment portions.

10. A shade covering for a blind, wherein the blind includes a plurality of slats and at least one cord ladder configured to support the slats, said shade covering comprising:
a plurality of attachment portions configured to be spaced apart from one another along a first direction of said shade covering, each said attachment portion defining an insertion slit and an attachment slit; and
a plurality of shade portions extending between adjacent pairs of said attachment portions;
wherein;
said insertion slit is defined through a rear end of each said attachment portion such that an insertion end of said insertion slit is open at said rear end; and
said attachment slit extends outwardly from said insertion slit at a location spaced apart from said rear end.

11. The shade covering of claim 10 , wherein said attachment slit terminates at an attachment opening, said attachment opening having a larger crosswise dimension than said attachment slit.

12. The shade covering of claim 10 , wherein said attachment slit is configured to receive a ladder run of the at least one cord ladder.

13. The shade covering of claim 12 , wherein:
each said attachment portion further defines a second attachment slit extending outwardly from said insertion slit and being spaced apart from said first attachment; and
said second attachment slit is configured to receive a lift cord of the blind.

14. The shade covering of claim 10 , wherein said attachment portions and said shade portions are formed from separate webs or from a continuous web.

15. The shade covering of claim 10 , wherein each shade portion includes a crease line, a lower wall segment extending between said crease line and a lower attachment portion of each of said adjacent pairs of said attachment portions, and an upper wall segment extending between said crease line and an upper attachment portion of each of said adjacent pairs of said attachment portions.

16. The blind assembly of claim 1 , wherein said attachment slit extends perpendicular to said insertion slit.

17. The blind assembly of claim 2 , wherein, after said front ladder run is received within said insertion slit, said shade covering is further installed onto said blind by moving said shade covering relative to said blind in a second direction defined at an angle relative to the first direction such that said font ladder run is received within said attachment slit.

18. The blind assembly of claim 5 , wherein a lateral spacing defined between said first and second attachment slits is equal to a lateral width defined between said front ladder run and said lift cord.

19. The shade covering of claim 10 , wherein said attachment slit extends perpendicular to said insertion slit.
