Abstract
ABSTRACT OF THE DISCLOSURE
An expandable and collapsible cellular shade formed from a single web of foldable material folded alternately in opposite directions along permanently set first and second creased folds disposed at opposite sides of the shade such as to form normally flat panels disposed in sidewise abutting relation and serially united in alter nate succession along respective first and second creased folds. The sidewise adjacent panels have adjacent faces bonded together along a narrow band parallel to and spaced from the creased fold therebetween and the panels and the permanently set creased folds have sufficient strength and resilience to normally maintain an acute angle between the panels at the creased folds when the shade is expanded to define pleats at opposite sides of the shade. When expanded, the shade defines a double row of overlapping cells.

SUMMARY OF TBE INVENTIO~
_ It is the general object of the present invention to provide an expandable and collapsible cellular shade formed from a single web of foldable material, which is 1~ collapsible to a compact condition and which has finished pleats at both sides of the shade when the shade is expanded.
Accordingly, the present invention provides an expandable and collapsible cellular shade comprising a 1~ single web of foldable material folded alternately in opposite directions along permanently set first and second creased folds respectively disposed at first and second sides of the shade such as to form a stack of normally flat panels disposed in flat sidewise abut~ing relation and serially united in alternate succession along respec-tive first and second creased folds~ The panels have the same transverse width measured between the associated first and second creased folds and sidewise adjacent panels that are united along each of the first creased folds have adjacent faces bonded together along a narrow first band parallel to and spaced from the associated first creased fold and sidewise adjacent panels that are united along each of the second creased folds have adja-cent faces mounted together along a narrow second band parallel to and spaced from the associated second creased fold. The panels are disposed in flat sidewise abutting relation when the shade is fully collapsed and the panels and the permanently set first and second creased folds 2~12~
therebetween have sufficient strength and resilience'to normally maintain an acute angle between the panels at the creased folds when the shade is expanded. Preferably, the first and second bands are respectively spaced from the second and first creased folds a distance substantially equal to the spacing between the first and second bands.

Fig. 2 is an end view of the shade on a larger scale than Fig. 1 and illustrating the shade in an expanded condition and Fig. 3 is an end view of the shade in a collapsed condition.
DEl'AIL~D DESCRIPTION
As shown in the accompanying drawings, the expandable and collapsible shade designated generally by the numeral S is formed of a single web of foldable material that is folded alternately in opposite directions along sharp permanently set first and second creased folds designated Fl and F2 disposed at opposite sides of the shade such as to form a plurality of normally flat panels ~ that are serially united in alternate succession along respective first and second creased folds. The crea~ed folds Fl and F2 are parallel to each other and are spaced apart a uniform preselected distance so that the panels P have the same transverse width designated W in Figs. 2 and 3 betwee'n the associated first and second creased folds Fl and F2. The web can be formed of various different mate-rials which are foldable and sufficiently stiff to retain permanently se~ creased folds. The web may, for example, be formed of ~uitable plastic film such as polyester film, or from woven and non-woven material formed from various fibers including natural and synthetic.' In the present ., 2~2~084 shade, one side of the web will be exposed at one side of the completed shade and the opposite ~ide of the web wîll be exposed at the opposite side of the completed shade.
Thus, opposite sides of the web can advantageously be formed with different physical characteristics such as different colors or textures or different aesthet~cs, or with a light reflection or absorbent surface on one side or the other for enhanced insulating characteristic~.
Sidewise adjacent panels that are united along each oE the first creased folds have adjacent faces bonded toge~her along a narrow first band designated Bl that is parallel to and spaced a predetermined distance designated ~1 in Figs. 2 and 3 from the associated first creased fold, and the sidewise adjacent panels that are united along each of the second creased folds F2 have adjacent faces bonded together along a narrow second band B2 that is parallel to and spaced the same distance Dl from the associated second crease fold, where Dl is greater than one-half the width W
of the panels and less than the full width of the panels.
The distance Dl is preferably preselected so as to be about two-thirds the width of the panels so that the distance designated D2 in Figs. 2 and 3 between the bands Bl and the fold lines F2 and the similar distance D2 between the bands B2 and the fold lines Fl is about one-third the width of the panels. Stated otherwise, thefirst and second bands Bl and B2 are respectively spaced from the second and first creased fold lines F2 and Fl a distance substantiaIly equal to the spacing between the firqt and second bands Bl and B2. Bands Bl and B2 are formed by a suitable adhesive and are preferably made relatively narrow, for example of the order of one eighth inch or les~
The sidewise adjacent panels P are normally flat and 2~2~
are collapsible into a compact stack in flat sidewise abutting relation as ~hown in Fig. 3 and, when the shade is expanded, the sidewise adjacent panels that are united along the first crease folds and bonded together along the S first bands define a first row of cells Cl therebetween and the sidewise adjacent panels that are united along the second creased folds F2 and bonded along the second bands B2 define a second row of cells C2 therebetween, with the first and second rows of cel`ls Cl and C2 overlapping in the area between the first and ~econd bands.
In order to ~acilitate mounting and expanding and collapsing the shade in a window opening, one end of the shade is attached to a head member designated HM and the other end of the shade is attached to a bottom member BM.
The panels P are formed with one or more rows of openings designated O at a location intermediate the bands Bl and B2, and a lift cord means L i9 attached to one of the members such as the bottom member BM and extends through the row or rows of openings and over guides G on the head-rail.
In making the shade, the ~eb of material is firstfolded and creased along the first and second fold lines Fl and F2 to form a stack of flat panels in flat sidewise abutting relation. Adhesive bands are advantageous:Ly applied after the web is folded and creased, by separating the panels between adjacent creased folds to allow appli-cation of the adhesive band to one or both of the sepa-rated panels.
From the foregoing it is believed that the construc-tion of the expandable and collapsible cellular shade willbe readily understood. The shade is formed from a single web of material with the permanently creased fold lines Fl and F2 disposed as opposite sides of the shade to provide 2 ~
finished pleats at both sides of the shade when the shade is expanded and improved stacking when the shade is col-lapsed. The creased folds form a unitary connection between adjacent panels and contribute to support of the lower portions of the shade when the shade is expanded.
Further, since opposite sides of the web of material are exposed at opposite sides of the compLeted shade, opposite sides of the web can be preformed to provide different aesthetic and/or thermal characteristics at opposite sides of the completed shade. Spacing the adhesive bands Bl and B2 from the associated creased fold lines F1 and F2 about two-thirds the width of the panels, allows maximum shade expansion and narrow adhesive bands Bl and B2 between adjacent panels provides a double row of overlapping cells 1~ Cl and C2 having a generally diamond shaped configuration when the shade is expanded. The lift cords extend down through the panels between the adhesive bands Bl and B2 and aL~e concealed from both sides of the shade.
