Dual-laminate honeycomb material

Abstract
A dual-laminate honeycomb panel permits the use of two or more different materials to form a single panel. In this manner, a retractable covering for an architectural opening may be formed that has a different appearance depending upon which side of the panel is being viewed. The resultant panel is formed by attaching a plurality of elongated precursor tubular cells, wherein each precursor tubular cell itself comprises two strips of material attached to one another.
Description




BACKGROUND OF THE INVENTION




a. Field of the Invention




The instant invention is directed toward a retractable cover for an architectural opening. More specifically, it relates to a cellular panel used to cover an architectural opening and a method of making the same.




b. Background Art




It is well known that cellular panels provide excellent coverings for architectural openings. For example, U.S. Pat No. 4,603,072 to Colson, the disclosure of which is hereby incorporated by reference, discloses a type of retractable honeycomb cellular panel. A typical honeycomb panel is constructed of a plurality of hollow slats or tubes, stacked and then adhered to one another to form a three-dimensional cellular structure when expanded. In its unexpanded state, the slats or tubes flatten to form a rectangular stack. The height of the stack is dependent upon the length of the panel and the material from which it is made. A retractable multi-cellular honeycomb insulating panel is disclosed in U.S. Pat. No. 5,482,750 to Colson et al.




A related type of honeycomb insulating panel is disclosed in U.S. Pat. No. 4,677,012 to Anderson. In the '012 patent, a cell of the panel is formed by folding a strip of material along longitudinally extending fold lines that bring the longitudinally extending edges of the material near each other. Then, a second length of material is secured to the longitudinally extending edges to form a cell. A plurality of these cells are then affixed together to form a panel. Another related type of honeycomb insulating panel is disclosed in U.S. Pat. Nos. 4,795,515 and 4,871,006 to Kao et al. The '515 patent is directed toward a process and machine for forming the honeycomb panel disclosed therein. According to the '515 patent, a plurality of attaching strips join pleat lines formed in each of the two sheets that comprise the front and rear surfaces of the completed panel. The '006 patent is directed toward a dual fluted shade. Again, in the '006 patent, a plurality of attaching strips join two sheets of fabric along corresponding pleat lines formed in each of the two sheets. Other panels, like those disclosed in the '515 and '006 patents, wherein strips connect adjacent sheets of fabric, are disclosed in U.S. Pat. Nos. 5,228,936 (and B 1 5,228,936) to Goodhue and U.S. Pat No. 4,673,600 to Anderson. The '600 patent also discloses a panel wherein the two sheets of material forming the front and back faces are joined directly together. The application that issued as the '600 patent was a division of application Ser. No. 796,035, which eventually issued as U.S. Pat. No. 4,622,255 to Anderson. U.S. Pat. No. 4,685,986 to Anderson also issued from an application that was a division of the '035 application. Whereas the '600 patent claims the honeycomb panel, the '986 patent claims a method of fabricating the panel.




Still another related type of honeycomb panel is disclosed in U.S. Pat. No. 4,631,217 to Anderson. In the panel disclosed in the '217 patent, strips of material are folded into Z-configurations, which are then stacked in layers that are adhered together. U.S. Pat. No. 4,676,855 to Anderson issued from an application that was a division of the application that issued as the '217 patent. Whereas the '217 patent claims the honeycomb panel, the '885 patent claims a method of fabricating the panel.




U.S. Pat. No. 4,019,554 and its corresponding reissue Pat. No. Re. 30,254 to Rasmussen disclose yet another related type of honeycomb panel. The panels disclosed in the '254 and '554 patents are formed by stacking precursor tubular members one on top of another, wherein the top surface of a particular precursor tubular member is bonded to the bottom surface of the next adjacent precursor tubular member, and the bottom surface of the particular precursor tubular member is bonded to the top surface of an adjacent precursor tubular member. The stacked and bonded precursor tubular members forming a resulting thermal insulating curtain.




Various machines are also known that are capable of manufacturing cellular panels at high speed. For example, U.S. Pat. No. 4,450,027 to Colson, the disclosure of which is hereby incorporated by reference, discloses an apparatus for manufacturing cellular panels. Related U.S. Pat. No. 4,631,108 to Colson, the disclosure of which is hereby incorporated by reference, issued from a continuation-in-part of the application that eventually issued as the '027 patent.




The cellular panels manufactured heretofore by interconnecting a plurality of individual precursor tubular cells have generally comprised precursor cells constructed from a single strip of folded material. The resulting elongated precursor tubular cells of a single material are then directly joined together to form a cellular panel. The machine disclosed in the '027 patent may be used to manufacture such panels. Since the precursor tubular cells have been manufactured from single strips of material, however, it has not been possible to obtain the advantages that may be available when the honeycomb panel is constructed of more than one type of material. One such advantage is the ability to construct a cellular panel that is to be used as a window covering wherein one type of material faces inward for viewing by people inside of the room and a second, different material, faces outward. The inward facing side of the panel could be made from an aesthetically pleasing material, whereas the outward facing side could be made from a heat reflective or heat absorptive material. One side of the panel could also be made from a light-blocking material. Similarly, if an installed panel will have a hidden side, each precursor cell may be constructed to have an aesthetically pleasing material on the visible side of the resulting panel and a less expensive, less attractive material on the hidden side of the panel.




SUMMARY OF THE INVENTION




It is desirable to be able to form each precursor tubular cell in a honeycomb panel constructed by interconnecting a plurality of individual precursor tubular cells from a plurality of material types rather than from a single type of material.




Accordingly, it is an object of the disclosed invention to provide an improved retractable cover for an architectural opening. The instant invention is an expandable and contractible honeycomb panel comprising a plurality of parallel rows of interconnected elongated precursor tubular cells, each of the precursor tubular cells being constructed of foldable and creasable material, and each precursor tubular cell comprising at least a first strip of material and a second strip of material. The second strip of material is arranged substantially parallel to the first strip of material, and the two strips are substantially equal in length. The first strip and the second strip are directly joined to each other. The combination of the first strip and the second strip comprises a dual-laminate component that is shaped to form a precursor tubular cell used to construct the honeycomb panel.




Thus, in a first aspect of the present invention, an expandable and contractible honeycomb panel having a front side and a back side comprises a plurality of elongated precursor tubular cells. Each precursor tubular cell is constructed of foldable and creasable material. Each precursor tubular cell comprises a first strip of a first material, and the first strip has a first longitudinal axis and a first length parallel to the first longitudinal axis. Each precursor tubular cell also comprises a second strip of a second material, and the second strip has a second longitudinal axis and a second length parallel to the second longitudinal axis. The second length is substantially equal to the first length, and the second longitudinal axis is arranged substantially parallel to the first longitudinal axis. The second strip is directly joined to the first strip, forming a dual-laminate component, which is then shaped into the precursor tubular cell such that the first material is on the front side of the honeycomb panel, and the second material is on the back side of the honeycomb panel.




In a second aspect of the present invention, a method of manufacturing an expandable and contractible honeycomb panel having a front side and a back side and comprising a plurality of elongated precursor tubular cells is described. Each precursor tubular cell is constructed of foldable and creasable material. The method comprises the steps of placing a first strip of a first material substantially parallel to a second strip of a second material in an overlapping configuration; directly joining the first strip and the second strip, forming a dual-laminate component; and folding the dual-laminate component into a precursor tubular cell. These steps are repeated to create a plurality of precursor tubular cells. Then, the method entails connecting the plurality of precursor tubular cells to form the honeycomb panel such that the first material is on the front side of the honeycomb panel, and the second material is on the back side of the honeycomb panel.




In a third aspect of the present invention, a method of manufacturing an expandable and contractible honeycomb panel having a front side and a back side, and comprising a plurality of elongated precursor tubular cells is described. Each precursor tubular cell is constructed of foldable and creasable material. The honeycomb panel is formed by laying out a first sheet of a first material; laying out a second sheet of a second material, such that the first and second sheets are substantially parallel and overlapping; directly joining the first sheet to the second sheet along a plurality of parallel connecting lines; cutting the joined first and second sheets adjacent one of the plurality of parallel connecting lines, forming a dual-laminate component having a first strip of the first sheet directly joined along a selected connecting line to a second strip of the second sheet. The dual-laminate component is then folded into a precursor tubular cell. These steps are repeated to create a plurality of precursor tubular cells. Then, the method entails connecting the plurality of precursor tubular cells to form the honeycomb panel such that the first material is on the front side of the honeycomb panel, and the second material is on the back side of the honeycomb panel.




A more detailed explanation of the invention is provided in the following description and claims, and is illustrated in the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Two embodiments of a cellular honeycomb panel


10


,


10


′ (see

FIGS. 8

,


9


,


20


, and


21


) comprising a plurality of elongated precursor tubular cells


12


,


12


′, each precursor cell


12


,


12


′ comprising two strips of material


20


,


22


,


20


′,


22


′, are disclosed. An advantage of the instant invention over the prior art is that the two strips may be of different materials. For example, polymer film, metallized film, nonwoven fabric, woven fabric, knit fabric, and the like. Thus, it is possible to make a cellular honeycomb panel


10


,


10


′ having a different look from its front


14


,


14


′ and back sides


16


,


16


′ using two different materials.




Referring first to

FIGS. 1-9

, a first embodiment of the present invention is described.

FIG. 1

shows an exploded isometric view of a dual-laminate component


18


used to make a cellular honeycomb panel


10


according to a first embodiment of the present invention. As shown in

FIG. 1

, each dual-laminate component


18


that is to be folded into the precursor tubular cell


12


, a plurality of which are assembled into a honeycomb panel


10


, includes a first strip of material


20


and a second strip of material


22


. In this first preferred embodiment of the invention, the first strip of material


20


has a first length


24


and a first width


26


. The first length


24


is the longitudinal distance between a first end


28


and a second end


30


of the first strip


20


parallel to a first longitudinal axis


32


. The first width


26


is the lateral distance between a first edge


34


and the second edge


36


of the first strip


20


along a line that is substantially perpendicular to the first longitudinal axis


32


. In the first preferred embodiment, wherein the precursor tubular cells


12


of the resulting honeycomb panel


10


are arranged horizontally (see FIGS.


8


and


9


), the first length


24


corresponds to the width of the resulting honeycomb panel


10


, and the first width


26


is related to the thickness of the resulting honeycomb panel


10


.




Similarly, the second strip


22


comprises a second length


38


and a second width


40


. The second length


38


is the longitudinal distance between a first end


42


and a second end


44


of the second strip


22


parallel to a second longitudinal axis


46


. The second width


40


is the lateral distance between a first edge


48


and a second edge


50


of the second strip


22


along a line that is substantially perpendicular to the second longitudinal axis


46


. In the first preferred embodiment, the second width


40


is approximately one-half of the first width


26


.





FIG. 1

also depicts the adhesive


52


, which is shown as a layer on a first side


54


of the first strip


20


. In the preferred embodiment the adhesive


52


is spread over the first side


54


of the first strip


20


in an area approximately the same size as a side (


66


or


68


in

FIG. 2

) of the second strip


22


. This may be seen to best advantage in

FIG. 2

, which is a cross-sectional view taken in the plane of line


2





2


of FIG.


1


.

FIG. 2

is an exploded cross-sectional view of the dual-laminate laminate component


18


that will be ultimately folded into one of the precursor tubular cells


12


that are joined to form the honeycomb panel


10


depicted in

FIGS. 8 and 9

. As shown in

FIGS. 1 and 2

, the adhesive


52


is approximately as wide as the second width


40


of the second strip


22


. When the second strip


22


is attached to the first strip


20


by the adhesive


52


, the dual-laminate component


18


shown in

FIG. 3

results.




The dual-laminate component


18


depicted in

FIG. 3

is then folded into a precursor tubular cell


12


as shown, for example, by

FIGS. 3

,


4


,


5


, and


6


. As shown by comparing

FIGS. 3 and 4

, a possible first step for forming a precursor tubular cell


12


comprises folding the dual-laminate component


18


of

FIG. 3

along a first fold line


56


and a second fold line


58


.

FIGS. 5 and 6

depict further progression of the fold until a second side


60


of the first strip


20


is folded against itself along the first fold line


56


and the second fold line


58


(see FIGS.


6


and


7


).

FIG. 7

depicts a flattened precursor tubular cell


12


according to a first embodiment of the present invention. A portion of the second strip


22


adjacent its first edge


48


is broken away to show the adhesive


52


between the second strip


22


and the first strip


20


. In this configuration, the first edge


34


of the first strip


20


is adjacent the second edge


36


of the first strip


20


. It should be noted that it is not necessary for hard creases to be present along the first fold line


56


and the second fold line


58


. As depicted, the first fold line


56


and the second fold line


58


do comprise sharp creases, which facilitates assembly of the honeycomb panel


10


from a plurality of precursor tubular cells


12


.




Referring now to

FIGS. 8 and 9

, assembly of the honeycomb panel


10


from a plurality of precursor tubular cells


12


formed according to the previous discussion is described. As shown in

FIG. 8

, two precursor tubular cells


12


according to the first embodiment are joined by a first adhesive bead


62


and a second adhesive bead


64


. In this preferred embodiment, the first adhesive bead


62


is applied to the first side


54


of the first strip


20


adjacent the first edge


48


of the second strip


22


. This first adhesive bead


62


thus extends parallel and adjacent the first longitudinal axis


32


. Alternatively, this first adhesive bead


62


could have been placed on the first side


54


of the first strip


20


of the next adjacent elongated precursor tubular cell


12


adjacent the first edge


34


of that first strip


20


. Either way, when two precursor tubular cells


12


are placed adjacent each other, the first side


54


of the first strip


20


of a first precursor tubular cell


12


(e.g., the lowermost precursor tubular cell as depicted in

FIG. 8

) is adhered to the first side


54


of the first strip


20


of the next adjacent precursor tubular cell


12


(e.g., the middle precursor tubular cell


12


as depicted in FIG.


8


). The second adhesive bead


64


may be applied to a first side


66


of the second strip


22


of either of two adjacent precursor tubular cells


12


. For example, as depicted in

FIG. 8

, the second adhesive bead


64


, which also extends longitudinally and substantially parallel to the first and second longitudinal axes


32


,


46


, respectively, could be applied to the first side


66


of the second strip


22


of the precursor tubular cell depicted in the middle of

FIG. 8

, adjacent the second edge


50


of the second strip


22


, or the second adhesive bead


64


could be applied to the first side


66


of the second strip


22


of the lowermost precursor tubular cell depicted in

FIG. 8

, adjacent the first edge


48


of the lowermost second strip


22


. Either way, when two precursor tubular cells


12


are placed adjacent each other and pressed together, the first side


66


of the respective second strips


22


of each adjacent precursor tubular cell


12


are affixed to one another.




The assembled panel


10


, a portion of which is shown in

FIGS. 8 and 9

, has a different appearance from its front side


14


when compared to the appearance from its back side


16


. When viewing the resulting honeycomb panel


10


from the front side


14


, only the material comprising the first strips


20


of each precursor tubular cell


12


is visible. In contrast, when viewing the resulting honeycomb panel


10


from its back side


16


, only the second strips


22


of each precursor tubular cell


12


comprising the panel


10


are visible. Thus, when the material used for the first strips


20


is different from the material used for the second strips


22


, the resulting panel


10


looks different when viewed from its front and back sides


14


,


16


, respectively. If desired, the first strip


20


could have a different appearance from its first and second sides


54


,


60


, respectively, and the second strip


22


could have a different appearance from its first and second sides


66


,


68


, respectively. Thus, additional variations could be obtained by controlling which side of the respective first and second strips


20


,


22


, are visible in the dual-laminate component


18


depicted in FIG.


3


.




Referring now to

FIGS. 10

,


11


,


12


,


13


,


14


,


15


,


16


,


17


,


18


,


19


,


20


, and


21


, a second embodiment of the invention shall be described.

FIG. 10

is an exploded cross-sectional view of an assembly


70


from which dual-laminate components


18


′ that will be formed into precursor tubular cells


12


′ are cut. As shown in

FIG. 10

, the assembly


70


comprises a first sheet of material


72


, a second sheet of material


74


, and a plurality of parallel connecting lines


76


, which are long beads of adhesive in the preferred embodiment, but which could also be, for example, lines of stitching or sonic weld lines. To form the assembly depicted in

FIG. 11

, the second sheet of foldable and creasable material


74


is laid down, and parallel lines of adhesive


76


are applied to the second sheet


74


. Then, the first sheet of material


72


is laid on top of the second sheet


74


. The lines of adhesive


76


secure the first sheet


72


to the second sheet


74


as shown in FIG.


11


. Once the assembly


70


depicted in

FIGS. 10 and 11

has been formed, a plurality of cuts


78


are made (FIG.


11


). Each cut


78


is made in the assembly


70


comprising the first and second sheets


72


,


74


, respectively, by cutting adjacent to one side of each adhesive bead


76


. This results in a plurality of subassemblies or dual-laminate components


18


′ like those depicted in

FIGS. 12-19

. Each of these dual-laminate components


18


′ comprises a first strip of material


20


′, a second strip of material


22


′, and an adhesive bead


76


attaching the first strip


20


′ to the second strip


22


′ along one edge of each strip. In particular, as best shown in

FIG. 14

, each dual-laminate component


18


comprises a first strip


20


′ having a first side


54


′, a second side


60


′, a first edge


34


′, and a second edge


36


′; and a second strip


22


′, also comprising a first side


66


′, a second side


68


′, a first edge


48


′, and a second edge


50


′. As shown, the adhesive


76


is between the first strip


20


′ and the second strip


22


′ so as to attach the second side


60


′ of the first strip


20


′ to the first side


66


′ of the second strip


22


′ near the second edge


36


′ of the first strip


20


′ and the second edge


50


′ of the second strip


22


′.




An exploded, isometric view of a dual-laminate component


18


′ according to the second preferred embodiment is clearly shown in FIG.


13


. The first strip


20


′ of material has a first length


24


′, parallel to a first longitudinal axis


32


′, between a first end


28


′ and a second end


30


′ of the first strip


20


′. The first strip


20


′ also has a first width


26


′, which is the perpendicular distance between a first edge


34


′ and a second edge


36


′ of the first strip


20


′ along a line that is substantially perpendicular to the first longitudinal axis


32


′. Similarly, the second strip


22


′ comprises a second length


38


′, which is the distance between a first end


42


′ and a second end


44


′ of the second strip


22


′ parallel to a second longitudinal axis


46


′. The second strip


22


′ also comprises a second width


40


′, which is a lateral distance between a first edge


48


′ and a second edge


50


′ of the second strip


22


′ along a line that is substantially perpendicular to the second longitudinal axis


46


′. As a result of how each dual-laminate component


18


′ is made in this second preferred embodiment, the first width


26


′ is substantially equal to the second width


40


′, and the first length


24


′ is substantially equal to the second length


38


′.





FIGS. 14

,


15


,


16


,


17


, and


18


show the steps of this preferred embodiment for folding the dual-laminate component


18


′ into a flattened precursor tubular cell


12


′ used to form the honeycomb panel


10


′ depicted in

FIGS. 20 and 21

. In particular, the dual-laminate component


18


′ depicted in

FIG. 12

is “opened” by folding the first edge


34


′ of the first strip


20


′ away from the first edge


48


′ of the second strip


22


′ along a third fold line


80


, until the first edge


34


′ of the first strip


20


′ is approximately as far away as possible from the first edge


48


′ of the second strip


22


′, as shown in FIG.


15


. Subsequently, the dual-laminate component


18


′ is folded along a first fold line


56


′ and a second fold line


58


′. The first edge


34


′ of the first strip


20


′ is then brought toward the first edge


48


′ of the second strip


22


′ as shown in

FIGS. 16 and 17

as the fold along the first fold line


56


′ and the fold along the second fold line


58


′ is increased. Ultimately, the configuration depicted in

FIGS. 18 and 19

is obtained. The configuration depicted in

FIGS. 18 and 19

shows a flattened precursor tubular cell


12


′ ready for assembly into a honeycomb panel


10


′ depicted in

FIGS. 20 and 21

. Although the discussion of this second embodiment and of the other embodiment refers to folds or creases, the instant invention does not require them. Creases may be beneficial for some uses of the invention and are used in this disclosure for illustrative purposes, but are not required and need not be severe or well-defined.




The process of gluing first and second strips


20


′,


22


′, respectively, together and of creasing the resulting dual-laminate component


18


′, repeated several times, produces a plurality of elongated precursor tubular cells


12


′. This plurality of elongated precursor tubular cells


12


′ may then be connected together to form a honeycomb panel


10


′ as depicted in

FIGS. 20 and 21

. As shown to best advantage in

FIG. 20

, a second adhesive bead


64

′ according to the instant invention.




Although two embodiments of this invention have been described above, those skilled in the art could make numerous alterations to the disclosed embodiments without departing from the spirit or scope of this invention. For example, although the first strip


20


is substantially twice as wide as the second strip


22


in the first embodiment, and although the first strip


20


′ and the second strip


22


′ are substantially the same size in the second embodiment, this need not be the case. Also, although folds have been variously designated “first,” “second,” and “third,” one of ordinary skill in this art would recognize that folds or creases could be made in a variety of different orders. Similarly, indications of direction or orientation (e.g., top and bottom) are for the convenience of the reader and should not be read as limiting. An important feature in this invention is that different types of material may be united directly to each other to form one or more of the individual, elongated precursor tubular cells


12


,


12


′ that are subsequently interconnected to form the resultant honeycomb panel


10


,


10


′. Also, although the honeycomb panels


10


,


10


′ depicted in the figures are oriented such that they expand and contract vertically, they could be hung such that they would expand and contract horizontally without departing from the scope of this invention. It is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative only and not limiting.
