Abstract
An expandable and collapsible window covering is disclosed in which an unpleated facing fabric is attached to a pleated panel to provide a Roman shade type window covering. Transverse cells are formed by the attachment of the pleated panel and unpleated fabric which provide excellent insulation properties. A method for making such a shade is also disclosed.
Claims12
An expandable and collapsible window covering, comprising:
- an expandable and collapsible pleated panel having a plurality of alternating oppositely directed spaced pleats;
- and
- a fabric sheet attached to said pleated panel along spaced apart joint lines extending transversely across the width of said pleated panel at spaced intervals with respect to said pleats of said pleated panel to form a plurality of stacked, transverse closed cells, said joint lines being spaced from said pleats to define discrete panel portions therebetween, the longitudinal direction of the individual cells being transverse to the direction of expansion and collapse of the window covering;
- and wherein each cell contains at least two adjacent pleats and
- the length of said fabric sheet between adjacent points of attachment is greater than the longitudinal spacing of said points of attachment with the window covering in the expanded condition.
An expandable and collapsible window covering, comprising:
- an expandable and collapsible pleated panel comprising a stack of folded strips bonded one on top of another, said stacked folded strips forming a plurality of alternating oppositely directed spaced transverse pleats of said pleated panel;
- a fabric sheet adhesively bonded to said pleated panel along joint lines extending transversely across the width of said pleated panel at periodically spaced intervals with respect to said pleats of said pleated panel, said spaced intervals containing at least two pleats, said joint lines being spaced from said pleats to define discrete panel portions therebetween, and wherein the length of fabric sheet extending between said spaced intervals is greater than the spacing of said intervals with said window covering fully expanded.
An expandable and collapsible window covering, comprising a panel of plural, stacked transverse cells, each cell comprising:
- a rear wall having a first portion joined to a second portion by a pleat directed outwardly with respect to the cell and third portion joined to said second portion by a pleat directed inwardly with respect to said cell, wherein said first portion is an integral extension of the third portion of the next adjacent cell in said stack;
- and
- a front wall of drooping fabric adhesively bonded to said rear wall along the extremity of said third portion opposite said second portion and along the extremity of said first portion opposite said second portion, said bonds defining the extent of the rear wall of said cell.
