    CROSS REFERENCE TO RELATED ORDER
    [001] The present application claims benefit, under 35 USC § 119 (e), from US Provisional Application Number 61 / 727,838, entitled “Covering For Architectural Openings With Coordinated Vane Sets” and filed on November 19, 2012, which is by this medium incorporated in its entirety by reference in this document. TECHNICAL FIELD
    [002] The present disclosure generally refers to covers for architectural openings, and more specifically, retractable covers for architectural openings. FUNDAMENTALS
    [003] Coverings for architectural openings, such as windows, doors, arcades, and the like have taken on various forms over the years. The initial forms for such coverings consisted mainly of draped fabric across the architectural opening, and in some cases, the fabric was not movable between the extended and retracted positions in relation to the opening. Some newer versions of covers can include cellular blinds. These blinds include collapsible tubes arranged horizontally that are stacked vertically and fastened on top of each other to form a panel of tubes. Cell tubes can trap air to help provide insulation. The stacked configuration provides insulation, but can be difficult to manufacture, when rows of cells must be created that are aligned with each other.
    [004] Many cellular blinds are retracted and extended by raising or lowering the lower cell, respectively. When the lower cell is raised, it is compressed against the other cells, collecting them one on top of the other; and, when the lower cell is lowered, the lower cell pulls open cells. When in a stowed position, typical cellular blinds are stored in a stacked configuration, that is, one cell on top of the other cells in a vertical line. This retracted configuration is necessary for some cellular blinds, as wrapping the cells around a main rail can damage the cells and prevent the cells from opening.
    [005] In addition, the most cellular blinds do not provide variation of light transmission through them. Instead, a cellular blind should normally be retracted or extended in order to vary the transmission of light across the roof. However, in some cases, it may be desirable to vary the light, without retracting the panel, for example, a cover for a bedroom window.
    [006] JPH06-73970 describes a window cover that has slats 7 arranged in parallel between the front and rear cloth curtains 6. DE 35 25 515 describes a curtain that can be rolled up, with adjustable blades. The blades are in fabric pockets arranged between two webs of fabric. The result is a curtain that is very easy to produce and capable, even in cases of open or absent glazing, to keep flying insects outside, in addition to protecting the light and visibility. The slats in this case can be manufactured as part of the fabric.
    [007] US 5,664,613 describes a window cover having a sheet of light-admitting material, which forms a backsheet and a series of spaced strips, generally parallel, attached at one edge of the backsheet and attached at an edge opposite a strip adjacent. Each strip contains a portion that prevents light and a portion that admits light. US 6,345,486 describes an expandable and contractable insulating honeycomb panel. The panel is formed by connecting a plurality of adjacent integrated tubular cell units.
    [008] US 6,068,039 describes a shutter for windows of the shutter type that has substantially flat front and rear layers made of transparent or translucent materials and transparent fabrics, preferably different. The space between these layers is permeated by bridges at regular intervals slightly smaller than the space. The bridges are made of strips of material or strips of single or double wires that support the blades that can be easily inserted or removed by the consumer. The blades can be flexible or rigid and prevent them from moving laterally through slits in their front and rear edges, through which the cables pass.
    [009] CN 1 925 774 describes a retractable cover for architectural openings having folding fins, including a support structure in the form of a sheet of material, monofilaments, adhesive tapes, tapes, cables or the like, supporting an upper edge of a plurality of vertically spaced fins that extend horizontally with the lower edges of the fins, in most embodiments of the invention, being connected to operational elements adapted to raise the lower edges of each fin towards the upper edges, in order to define openings or gaps between the fins through which vision and light can pass in an open condition of the roof. SUMMARY
    [0010] Examples of modalities described in this document may take the form of a cover for an architectural opening. The cover can include a main rail, an end rail and a panel extending between the main rail and the end rail. The panel may include a front sheet, a back sheet operably coupled to the front sheet, and a cell extending between the front sheet and the back sheet. When the first sheet is in a first position in relation to the back sheet the cell is opened and when the first sheet is in a second position in relation to the back sheet the cell is closed.

    [0033] Some modalities described in this document can take the form of a cover for an architectural opening including operable fins that also form insulating cells. The cover can include a front leaf and a rear leaf. One or more cells extend between the two sheets, connecting the two sheets together. The roof can be retracted and extended to cover an architectural opening. This can allow the panel, including the cells, to be wrapped around a roll, reducing a retracted height of the cover. In addition, the cells can be opened or closed, and depending on the materials used in the cover, the opening and closing of the cells can vary the light transmittivity of the cover.
    [0034] When the cells are closed, each cell can be substantially compressed, and the material that forms each cell can be substantially parallel to each of the leaves. In some embodiments, a length or the body of each of the cells may be adjacent to each other or partially overlap so that the cells can form an intermediate pseudo-sheet positioned between the front and rear leaves. When the cells are open at least to a certain extent, each cell can be at least partially perpendicular or angled with respect to at least one of the leaves. In an open configuration, cells can then provide insulation by retaining air in each cell, as well as between adjacent sets of cells. In addition, the cells can reduce or diffuse the shadows created by the structure of the roof on one side being so visible on the other side of the roof. In other words, the shadow lines due to the light that meets the shadow on the outside of the shadow, whether or not at a specific angle of incidence, can be reduced as seen from the inside of the roof. General Cellular Coverage and Operation
    [0035] The roof, as disclosed in this document, can be used to cover substantially any type of architectural opening, such as, but not limited to, windows, door frames, arcades, and the like. Referring generally to figures 1A-1C, the cover 100 can include a main rail 102, having a main tube or roller 126 (see figure 2A) that supports an upper edge of a panel 104 and an end rail 110 supported by an edge bottom of panel 104. For example, front leaf 118 can be connected at connection point 103 to the roller and at connection point 105 to the end rail and the rear leaf 120 can be connected at connection point 107 to the roller and at the connection 109 to the terminal rail. Main rail 102 can support panel 104 over an architectural opening and thus can generally correspond to the shape and dimensions of the architectural opening. Figure 1A is a perspective view of the panel 104 of the cover 100 extended with the cells in an open configuration. Figure 1B is a perspective view of the panel 104 of the cover 100 extended with the cells in a closed configuration. Figure 1C is a perspective view of panel 104 of cover 100 substantially retracted on main rail 102.
    [0036] The cover 100 may also include a system for controlling the retraction, extension, and orientation of the fin when extended. In one example, the system may include a control cable 106 and suspended cable end 108 for opening and closing cells 112 of panel 104, as well as retracting and extending panel 104 through the architectural opening. As is known, the system can also include a pulley over which the cable extends, the rotation of the pulley triggering the rotation of the main tube. The pulley can be in a direct drive arrangement with the main tube, or it can be connected via a gear train and / or coupling mechanism. In one example, the end of the cable 108 can provide weight for the control cable 106, to maintain the shape of the control cable 106. The end of the cable 108 can also pick up additional material from the control cable 106 when the panel 104 is extended or retracted, so that control cable 106 can remain substantially the same length when panel 104 is retracted or extended. In addition, the system for controlling the rotation of the main tube may include an electric motor that is controlled manually by a user, or through the programmable or pre-programmed software control unit.
    [0037] It should be noted that control cable 106 and / or cable rod 108 can be operatively associated with panel 104 and can be substantially any type of control mechanism, for example, infinite loop cable, single cable, rotating pole , and so on. In many embodiments, control cable 106 and / or rod 108 are configured to move panel 104 to open and close cells 112 and to move terminal rail 110 up and down.
    [0038] Panel 104 may include a front sheet 118, a back sheet 120, and cells 112 that extend between the two sheets 118, 120. Cells 112 in panel 104 are defined at least in part by an upper fin 114 and a lower fin 116. The upper fin 114 and the lower fin 116 can be interconnected together, and each can be connected to a front leaf 118 and a back leaf 120. The interconnection between the fins 114, 116 and the front and rear 118, 120 is discussed in more detail below with respect to figure 3. Each cell then includes at least in part a set of coordinated fins that move along with the movement of either or both the front and rear sheets.
    [0039] The front sheet 118, the back sheet 120, and the fins 114, 116 can be substantially of any type of material, such as, but not limited to, knits, fabrics, nonwovens, and so on. In addition, sheets 118, 120 and fins, 114, 116 can have different translucent properties, ranging from blackout, opaque, partially opaque, or clear. In some cases the leaves 118, 120 may have an increased light translucency compared to the fins, so that when the fins 114, 116 are closed the light translucency of the cover can be varied.
    [0040] To open and close cells 112, leaves 118, 120 are moved relative to each other in a direction orthogonal to the length of the fin (that is, vertically in relation to figure 1A), the interior volume or cavity 122 of the cell changes. In other words, the sheets can be moved by a force that can generally be parallel to each of the sheets, such as a vertical upward force provided when the roller changes position. For clarity, in this document, as described, the interior volume, or cavity, of the cell is represented by the cross-sectional area of the interior of the cell. For example, when the cover is in the fully extended configuration, as in figure 1A, the cell defines a larger interior volume. When the leaves 118, 120 are moved relative to each other, the connected portions of each fin, 114, 116, with the respective leaf are moved, and the internal volume of the cell decreases. When the sheets, 118, 120 are moved additionally in relation to each other, the internal volume is reduced to a minimum size (see figure 1B), at the point where the cell is considered "collapsed" or closed and the panel is prepared for retraction on the main rail (see figure 1). Figure 2A is an elevation view of the cover of Figure 1A with the end cap removed to illustrate the roll, with cells 112 in the open position. In these cases, although the movement of the leaves can be substantially parallel to each other (due to the force applied upward by the roller), when cells 112 retract, leaves 118, 120 can be moved horizontally closer together (see figures 5A-5C). When cells 112 are in an open configuration, the fins 114, 116 can be moved away from each other to define a cavity between them 122. In this position, the fins 114, 116 can extend so that the portion of each fin 114, 116 can be at least partially perpendicular or angled to the front leaf 118 and the rear leaf 120. In this configuration, the cell volume is relatively large.
    [0041] When cells 112 are in the open configuration, the fins, 114, 116 can be moved away from the other group, or sets, of fins, 114, 116 to define slots 124 between each cell 112. These slits 124 may allow the light is transmitted uninterruptedly through the cracks in the rear leaf 120 to the front leaf 118, especially in embodiments where the front leaf 118 and the rear leaf 120 are both translucent.
    [0042] Figure 2B is a side elevation of the cover of figure 1B, with the end cap removed to illustrate the roll. In figure 2B, cells 112 are in an intermediate configuration between being fully open and fully closed, such as when moving from an open position to a closed position. In the example shown in Figure 2B, the panel 104 can be oriented to extend from a front side of the roll 126 and therefore can be screwed around a front side of the roll. When the front sheet 118 and / or the back sheet 120 is displaced vertically with respect to the other sheet, the inner volume of cells 112 decreases in size, as shown in figure 2B. In this configuration, the height of the gap 124 is reduced since the lower edge 115 of an upper cell 117 is approached to an upper edge of the adjacent lower cell. This is described in more detail below.
    [0043] Figure 2 is a side elevation view of the cover of figure 1B, with the end cap removed to illustrate the position of the roller. When the backsheet 120 or the backsheet 118 continues to be displaced relative to each other, cells 112 will continue to collect until the inner volume 122 between the fins, 114, 116 in each cell is at its lowest configuration. In this configuration, the fins 114, 116 of each cell 112 can be substantially parallel to the front sheet 118 and the back sheet 120. When cells 112 are in this closed configuration, the cavity 122 defined by the upper fin 114 and the lower fin 116 can be substantially eliminated.
    [0044] When cells 112 are closed, cracks 124 can also be reduced and / or eliminated. This is because the open distance, Gopen (defined below with respect to figure 3) between a lower edge 119 of an adjacent upper cell and an upper edge 121 of a lower cell is eliminated, with the two edges 119, 121 possibly overlapping. In this way, cells 112 can form a multi-layer pseudo-sheet positioned between the front and rear leaves 118, 120. Depending on the transmissivity of the fin materials, in the closed configuration the fins 114, 116 can block the light at least partially or substantially to be transmitted through the backsheet 120 to the backsheet 118. A more detailed description of the movement of the fins 114, 116 and the configuration of the cells 112, while the panel 104 is retracted or extended is discussed below in relation to figures 5A- 5C.
    [0045] Referring briefly to figures 1C and 2C, when the cover 100 is retracted, the panel 104 can be wrapped around a roll 126. When the roller 126 rotates in a certain direction, the panel 104 is screwed around from the outer surface of roll 126. To retract panel 104, roll 126 can screw in the opposite direction by unrolling panel 104.
    [0046] To open or close cells 112, the roll 126 may return a partial rotation, for example, a quarter of a turn, to move sufficiently vertically one of the sheets 118, 120 relative to the other. For example, the two sheets, 118, 120 can be connected to the roll 126 and be spaced apart from each other, so when the roll 126 rotates, the sheets 118, 120 can be displaced relative to each other because a height of a sheet 118, 120 can be varied with respect to the other sheet 118, 120, when the roll 126 is rotated. As can be seen in figures 2A-2C, when the roller rotates, the connection points, 103, 107 of the front leaf and the rear leaf for the roller can change their position with respect to each other. In figure 2A, the connection points 103, 107 can both be positioned on a lower edge of the roller that is exposed through the main rail. In figure 2B, the connection points 103, 107 can be partially offset with each other, with the front leaf 118 of the connection point 103 being located on a portion of the roll received within the main rail and the rear leaf 120 of the connection point. connection 107 being positioned on the exposed portion of the roller in an opening of the main rail. And, in figure 2C, the front leaf of the connection point 103 can be located additionally inside the main rail, and the rear leaf of the connection point 107 can be closer to a right side (in relation to figure 2) of the main rail. .
    [0047] Front sheet 118 and back sheet 120 can function as the operational elements for opening and closing cells 112. Thus, the manufacturing process for cover 100 can be simpler than conventional covers, including fins operable. For example, in the creation of panel 104, the fins 114, 116 can be attached to the leaves 118, 120, without requiring the placement of the operational elements between the fins 114, 116 and the leaves 118, 120.
    [0048] It should be noted that the front leaf 118 and the rear leaf 120 can be displaced in relation to each other in many other ways, and the aforementioned embodiments are intended as exemplars only. Similarly, panel 104 can be retracted and extend substantially in any way. Cell Structure in Detail
    [0049] As briefly described above, cells 112 for cover 100 are formed at least in part by a set of two fins, such as an upper or higher fin 114 and a lower or lower fin 116. The figure 3 is an enlarged side elevation view of the cover 100 of figure 1A. Each cell 112 is a tube having side walls 123, 125 that define a cavity 122, cell 112 extending over the entire width of the cover 100. Each cell 112 is generally parallel to the adjacent cell above and adjacent below it. Each cell 112 can be constructed of a piece of material integrally formed to define the side walls 123, 125 of a tube, separate strips, such as fins 114, 116, connected together to define side walls 123, 125 of a tube, separate the strips or fins attached to the front and / or back sheets 118, 120, which together define side walls 123, 125 of a tube, or a piece of material attached to the front or back sheet which together define side walls of a tube.
    [0050] Figure 3 shows an example of a panel construction where cell 112 is positioned between a front sheet 118 and a back sheet 120. Cell 112 defines a closed tube without requiring any portion of the front or back sheets. In this way, cell 112 can be constructed from an integral sheet of material formed in a tube, or two or more separate fins connected together to form a tube. Cell 112 in this example is two fins 114, 116 connected together, and defines two opposing apexes 132, 136, one adjacent to the front leaf 118 and one adjacent to the rear leaf 120. With the continuous reference to figure 3, the upper fin 114 is extends between the front leaf 118 and the rear leaf 120. When the upper fin 114 approaches the front leaf 118, it can extend substantially parallel to a rear surface of the front leaf 118. The upper fin 114 may have a pleat spike 132 , apex, or tip at the top of the portion parallel to the front sheet 118. The upper fin 114 can extend downwardly from pleat 132 and can be operatively connected to the front sheet 118 on a first front connecting member 146. The first connecting member 146 can be located coextensively with crease 132 or in a position below or above crease 132.
    [0051] After locating the first connecting member 146, the upper fin 114 extends downwards to form a side wall 154 which can be partially or substantially parallel to the front leaf 118. The side wall 154 folds out towards the rear leaf 120 and is connected via a second front connecting member 148 to the rear face 150 of the first leaf 118. The second front connecting member 148 can be aligned with a lower curve or point and fold of the lower fin 116. In one example , the side wall 154 may have a slight curve such as an "S" shape when it transitions from the location of the first front connecting member 146 to the location of the second front connecting member 148. In addition, as shown in figure 3, the upper fin 114 of the side wall 154 transitions to form the lower fin 116 on or after the location of the second front connecting member 148.
    [0052] When the upper and lower fins 114, 116 in this example are formed from a single piece of material, the lower fin 116 can be connected at the location of the second front member 148 and can bend out and transition away from the sheet front 118 at fold point 140. The bottom flap 116 extends horizontally from front sheet 118 to connect to back sheet 120. When bottom flap 116 approaches back sheet 120, it curves upward toward to main rail 102 at bend point 138, in an opposite direction from bend point 140. In one example, the bottom fin 116 may have two bends or bends 138, 140 that are curved in opposite directions. In other words, the first curve point 140 extends the lower fin 116 downwards towards the end rail 110 and the second curve point 138 extends the lower fin 116 upwards towards the main rail 102. Thus, the lower fin 116 can be shaped as an "S" or other curved shape.
    [0053] At the bottom of the second curve point 138, the lower fin 116 transitions to the lower crease 136, or point. The bottom pleat 136 can be directed towards the end rail 110 and can be positioned opposite to the top fin fold 132. Similar to the top fin fold 132, the bottom fin 116 can be connected to the back sheet 120 (via a second rear connecting member 144) adjacent to or coextensive with pleat 136.
    [0054] With continuous reference to figure 3, the lower fin 116 transitions upwards from the pleat 136, forming a rear side wall 152. The rear side wall 152 can be substantially parallel to the rear leaf 120 and can have a shape corresponding to the front side wall, 154. The side back wall 152 is operatively connected to the inner surface 156 of the back sheet 120 through a first rear connecting member 142. The first rear connecting member 142 can be located near a transition between the lower fin 116 and the upper fin 114.
    [0055] After the location of the first rear connection member 142, the lower fin 116 curves at the fold point 134, transitioning to the upper fin 114. The upper fin 114 extends between the two sheets 118, 120 and curves- at a second fold point 130 to transition to pleat 132.
    [0056] It should be noted that the upper fin 114 and the lower fin 116 can be complementarily molded, and the two fins 114, 116 can generally trace the overall shape of each other. In this way, the fold or inflection points of each fin, 114, 116 can be aligned and curved in the same direction. This complementary structure can allow the upper fin 114 and the lower fin 116 to be compressed together, for example, when cells 112 are closed, as shown in figure 5. In one example, the fins can be 114, 116 defined by heat and folded, which can determine the open shape of cell 112. For example, fins 14, 116 can extend away from the attachment locations for sheets 118, 120 at wide or narrow spacing angles, depending on whether the fins, 114, 116 include pleats are defined by and folded or just fixation points without a separate heat-defined or otherwise permanent or semi-permanent pleat formed therein. In addition, the fins 114, 116 can include tissue reinforcements to provide a desired cell shape 112 substantially without inclination in the open configuration. In other examples, the fins 114, 116 can include fibers, or they can be at least partially rigid material that can maintain their shape or they can be at least partially resistant so that it can return to its original shape after deformation.
    [0057] Connecting members 142, 144, 146, 148 operatively couple the fins 114, 116 to the leaves 118, 120, when the leaves 118, 120 move the fins 114, 116 can move accordingly. Connecting members 142, 144, 146, 148 can be substantially of any type of connecting component, such as, but not limited to, adhesive, fasteners, stitching, hook and loop, and so on. In some examples, the connecting members, 142, 144, 146, 148 can extend across the entire width of the respective front leaf 118 or rear leaf 120. In this way, the fins 114, 116 can be operatively connected to the leaves 118, 120 substantially along its entire width.
    [0058] Connecting members 142, 144, 146, 148 can be separated from each other at different distances. The distance of each connecting member 142, 144, 146, 148 that is spaced out can determine the opening and closing characteristics of cells 112, as well as the shape of cells 112. For example, the spacing can determine the size of the cell cavity , as well as the size of the slots defined between each of the cells.
    [0059] As shown in figure 3, in an example, the first front connecting member 146 and the second front connecting member 148 can be positioned on the rear surface 150 of the front leaf 118 at an height H1 with each other. Similarly, the first rear connecting member 142 and the second rear connecting member 144 can be separated from each other on the rear sheet 120 by a height H2. The heights H1 and H2 can be substantially the same so that the fins 114, 116 in the open position can extend substantially horizontally between the two sheets 118, 120 or the heights H1 and H2 can be different and the fins 114, 116 can be angled to the extent between the front leaf 119 and the rear leaf 120.
    [0060] The heights H1 and H2 may vary depending on the desired volume of cavity 122 of cell 112 and / or the height of cells 112. In addition, in some embodiments, the upper fin 114 and / or the lower fin 116 can be interconnected with a respective sheet 118, 120 along the entire H1 and H2 heights. In other words, the first and second connection members can be combined to form a single connection member. However, in these embodiments, cell 112 may be more rigid than in embodiments with two separate connection locations.
    [0061] Furthermore, when cells 112 are open, the first front connecting member 146 can be moved away from the second rear connecting member 144 by a height H3. The height H3 varies when cells 112 are opened and closed. This transition and the height variation will be discussed in more detail below with respect to figures 5A-5C.
    [0062] The interconnection of the fins 114, 116 and the connection of the fins 114, 116 to the leaves 118, 120 form cells 112 for the panel of 104. The structure of the cell 112 of the fins 114, 116 provides the isolation of a first side from cover 100 to a second side of cover 100. Cells 112 retain air pockets in cavities 122, which act as a shock absorber to provide insulation. Thus, a room temperature on the back side of panel 104 cannot affect the temperature of a room on the front side of panel 104. For example, with a window like the architectural opening, cells 122 can retain air preventing cold air from a first side of the window that can be exposed to exterior elements by decreasing the air temperature on the front side of the window.
    [0063] Additionally, cells 112 can be positioned separately from each other by a gap 124. Slots 124 formed between cells 112 can also act to trap air and provide additional insulating properties to cover 100. When cells 112 are fully open , the cracks 124 may have a Gopen height (for example, when the panel is in the open configuration shown in Fig. 2A). The Gopen height can be defined as the height between the lower apex of fold 136 or the lowest point of an upper cell and the upper apex of fold 132 of an adjacent lower cell or the most upper point of the lower cell. The Gopen height can define the height of light rays, which can be transmitted through the front leaf 118 and the rear leaf 120 between cells 112. In this sense, as the Gopen height between cells changes, so does the amount of light rays that can be transmitted through the cover 100 without meeting the cell material, that is, they pass through the front leaf 118 and the rear leaf 120 only.
    [0064] The insulating characteristics of the cover 100, in addition to the operable nature of the fins 114, 116 to vary the light transmission, provide multiple resources from a single cover. When cells 112 are open, the fins 114, 116 are spaced from each other to define a cavity 122 between them, see, for example, Fig. 3. In addition, each cell 112 defined by the fins 114, 116 is spaced from the adjacent cells 112, defining the gaps 124 between each row of cells 112. When cells 112 are closed, fins 114, 116 may be adjacent to each other or may be in contact with a portion of the other fin 114, 116. Thus , the cavity 122 can be substantially reduced, as well as the crevices 124 between cells 112, in some cases, the Gopen height can be completely reduced so that there is very little distance (if any) between the lower apex 136 or the lowest point of an upper cell and the upper apex 132 or the uppermost point of an adjacent lower cell, see, for example, Fig. 5C.
    The fins 114, 116 can be strips of a material at least partially flexible interconnected to the sheets 118, 120 horizontally over a width of the panel 104. The fins 114, 116 can be flexible and still rigid. For example, the fins 114, 116 must be flexible enough that they can be compressed to a substantially flat position without being damaged, for example, see Fig. 2C; however, be sufficiently rigid so that they can maintain their shape when cells 112 are open, see, for example, Fig. 2A.
    [0066] In addition, the structure of cell 112 of fins 114, 116 also diffuses shadows formed from the light transmitted through the cover at an angle not perpendicular to it. In this way, shadows can be substantially prevented from being transmitted through panel 104. This can be especially evident in the examples where the front sheet 118 and the back sheet 120 are transparent or, otherwise, have a high light transmittance. Fig 4A is a side elevation view of a cover 200, including only a single fin 210. The fin 210 is connected to the front sheet 218 through a first adhesive 212 and to the back sheet 120 through a second adhesive 214. The adhesive 212, 214 attaches flap 210 to the two sheets 218, 220.
    [0067] With continuous reference to Fig. 4A, as the light meets the rear leaf 220 (for example, if the cover is positioned over a window), the light can be transmitted through the rear leaf 120 and the adhesive 214 blocks part of the light; however, other rays of light can pass through the backsheet 220 without being blocked. Thus, the light blocked by the adhesive 214 can form a shadow 216. As the fin 210 is positioned above the shadow 216, the shadow 216 can be transmitted to the front sheet 218 and can be visible on the front side of the cover.
    [0068] Eyeshadow 216 may appear black and / or darkened portions or spots on the front side of coverage 200, which can be aesthetically unpleasant. In addition, stains can cause the material of the front sheet 218 to fade unevenly due to exposure to light.
    [0069] In contrast, coverage 100 of the present disclosure can eliminate dark spots due to shadows. Fig. 4B is an enlarged side elevation view of the cover 100 being exposed to light. Although a shadow 216 can be created as the light is blocked by the first rear connection member 142, which can include an adhesive, shadow 216 can be diffused by the lower fin 116. The lower fin 116 can substantially reduce the appearance of shadow 216 and therefore, it can create a diffuse shadow 230. The diffuse shadow 230 may not reach the front sheet 118, thus preventing dark spots or portions from appearing on the front sheet 118. In cases where the shadow can reach the front sheet 118, the The shade can be so light that it cannot create a darkened stain on the front side of the cover 100. Consequently, the cover 100 can have a substantially uniform fading, in comparison with the cover 200 of Fig. 4A, as well as being aesthetically more attractive. Opening and Closing the Cells
    [0070] The opening and closing operations of cells 112 will be discussed now. Cells 112 can be opened and closed by varying a spacing distance D1 between the front sheet 118 and the back sheet 120, as well as changing the relative heights or orientation of the sheets 118, 120 relative to each other. For example, as shown in Fig. 3, when cells 112 are completely open, leaves 118, 120 can be spaced apart by a distance D1. The distance D1 can correspond to a horizontal width of the fins 114, 116 which extends between the two leaves 118, 120.
    [0071] As briefly described with reference to Figs. 2A-2C, the movement of the leaves 118, 120 in relation to each other can be carried out by the control cable 106 and the front rail 102 and / or the end rail 110. The leaves 118, 120 can move vertically, generally parallel with respect to to the second sheet, which can be accomplished substantially anyway. The opening and closing of cells 112 will be described in this document as the movement of the front sheet 118 in relation to the back sheet 120. However, it should be noted that other modalities are possible. Specifically, the backsheet can be moved, as well as or instead of moving the front sheet, see, for example, Figs. 12A - 12C. In this sense, the previous discussion is conceived as exemplary only.
    [0072] As shown in Fig. 3, when cells 112 are in the fully open position, the first front connecting member 146 and the second front connecting member 144 can be separated by a vertical height (in relation to the length of the cover 100 ) from an H3 height. Fig. 5A is a side elevation view of cells 112 in an open configuration for the most part, as cells 112 move from open to closed. As the backsheet 120 experiences downward force, the frontsheet 118 can remain substantially in its original position. Thus, the fins 114, 116 are pulled down with the backsheet 120, pulling the sheets 118, 120 closer together, since the fins 114, 116 are connected to each sheet 118, 120. For example, the distance D2 that separates sheets 118, 120, when cells 112 are mostly open is less than the distance D1 that separates sheets 118, 120 when cells 112 are fully open. Although downward force can generally be applied parallel to the two sheets, as the sheets move vertically relative to each other, the fins provide a horizontal force that pulls the sheets together. This horizontal force is due to the vertical displacement of the connection points of the fins, discussed in more detail below.
    [0073] Furthermore, the height between the first front connecting member 146 and the second rear connecting member 144 is extended to a height H4. The height H4 can be greater than the height H3, as the fins 114, 116 move from a relatively perpendicular orientation in relation to the leaves 118, 120 to an angled orientation.
    [0074] Fig. 5B is a side elevation view of cells 112 in a partially closed configuration, as cells 112 move from open to closed. If the backsheet 120 continues to experience a downward force F, the distance between sheets 118, 120 reduces the distance D3. In addition, the height between the first front connecting member 146 and the second rear connecting member 144 increases to a height of H5. The fins 114, 116 thus pass in order to be substantially parallel to the leaves 118, 120 and the cavity 122 is reduced in volume as the cells 112 fold.
    [0075] As the back sheet 120 continues to experience a downward force F and the front sheet experiences an upward force, cells 112 close. Fig. 5C is a side elevation view of cells 112 in a substantially closed configuration. The sheets 118, 120 can then be positioned substantially adjacent to each other and separated by a distance D4, which can be significantly less than the open distance D1. In some examples, the distance D4 can be substantially zero, that is, the sheets 118, 120 can be substantially in contact with each other. In addition, the first front connection member 146 can be separated from the second rear connection member 144 by a height H6, which can be greater than the other heights that separate the two connection members 144, 146. In this configuration, the fins 114, 116 can be positioned substantially parallel to the leaves 118, 120, as shown in Fig. 5C. In addition, since the fins 114, 116 are substantially parallel to the leaves 118, 120, the cavities of cell 122 can be substantially folded, folding cells 112. In the configuration shown in Fig. 5C, the Gopen height between the highest apex the lower 136 of the upper cell and the higher apex 132 of the adjacent lower cell can be substantially, if not completely, reduced, so that little to no light can be transmitted through panel 104 without being transmitted through the material of cells 112.
    [0076] Once cells 112 are closed, as shown in Fig. 5C, panel 104 can be remade around roll 126. The folded or closed configuration of cells 112 allows panel 104 to be rolled up without damaging the shape of fins 114, 116 and thus cells 112. Thus, unlike conventional cellular blinds, cover 100 provides insulation, variable light transmission, as well as rolled-up storage or retracted configuration. Alternative Cell Examples
    [0077] The cells 112 of the cover 100 can be formed in different shapes, and the connecting members and locations between the fins 114, 116 and the leaves 118, 120 can be changed. As discussed above, cells 112 can be formed from two interconnected fins, a single piece of folded material and interconnected to themselves or multiple sheets of material. In one example, fins 114, 116 can be connected to each sheet 118, 120 in a single location. Fig. 6 is a side elevation view of an exemplary cell 112, where the fins 114, 116 are connected to the front leaf 118 and the rear leaf 120, respectively, by a connecting member 244, 246. In this example, the pleats 132, 134 that form the upper and lower tips of the fins 114, 116, receptively, can be free or detached from the leaves 118, 120. In this embodiment, the pleats 132, 136 can be adjusted in the material that forms the fins 114, 116 ( for example, heated or chemically folded) so that they can be, at least partially, rigid to maintain the bend point. In this example, cells 112 can be substantially more flexible than in other embodiments.
    [0078] Additionally, the shape of cells 112 can be configured differently. Figs. 7A and 7B illustrate alternative cell shapes. In cell 112 shown in Fig. 7A, the fins 114, 116 can be less "S" shaped and more "C" shaped, in other words, the curves can be less defined than cell 112 of Fig. 3. The example in Fig. 7A, the fins 114, 116 can have a greater starting angle away from the leaves 118, 120. In addition, the cavity 122 can be larger, trapping more air and providing greater insulation, compared to the cells 112 of Fig. 3. However, as cell 112 has a larger cavity volume 122, the fins 114, 116 can block more light that can be transmitted through the cracks 124, since the cracks 124 may be smaller.
    [0079] As shown in Fig. 7B, cell 112 may have a narrower cavity 122 formed from a small starting angle, conforming the fins 114, 116 transit from the connection points to the leaves 118, 120. In the examples of Fig. 7B, the fins 114, 116 can provide less insulation than the shape of the cell of Fig. 7A. However, in the example in Fig. 7B, more light can be transmitted through cover 100 (if clear or highly transmissive materials are used for sheets 118, 120) because cells 112 may be reduced in height compared to cells in Fig. 7A.
    [0080] In some examples, cells 112 may be created by a single piece of material or by multiple pieces of material connected together. Fig. 8 illustrates an exemplary cell 112 formed by a material superimposed on itself and connected together. The lower fin 116 partially overlaps a terminal edge 256 of the upper fin 114. Instead of being connected together, the terminal edge 256 of the upper fin 114 is received within a flap 300 of the lower fin 116. The upper fin 114 is connected to the lower fin via a connecting member 54. The fin connecting member 254 can be substantially similar to the connecting members 142, 144, 146, 148 and the fin connecting member 254 can be an adhesive, hook and loop or other fastener.
    [0081] The flap 300 may be operatively connected to the inner surface 156 of the backsheet 120 by the connecting member 144. A free end 258 of the flap 300 may extend beyond the connecting member 144 and the flap connecting member 254.
    [0082] In another example, cells 112 may include multiple layers. In these examples, the insulating properties of panel 104 can be increased, as air can be received more firmly within cavity 122. Fig. 9 is an enlarged view of a single cell 112 formed by the overlapping material on itself and connected . In this way, the upper fin 114 and the lower fin 116 can each have a first or outer layer 304 and a second or inner layer 306. The two layers combine to form each fin 114, 116. The material is connected by connection member 302. The location of connection member 302 is shown to be located in the lower crease 136; however, it can be positioned substantially anywhere else.
    [0083] In other examples, the two layers 304, 306 can be formed, connecting two separate pieces of material to each other. Fig. 10 is an enlarged side elevation view of cell 112, including the two layers 304, 306. The two layers are connected by a second connecting member 308, in addition to the connecting member 302 shown in cell 112 of Fig. 9 In this example, the second connection member 308 is located at pleat 132. Thus, cell 112 can be connected by the first connection member 302 in pleat 136 and the second member 308 in pleat 136. It should be noted that other connection locations are also possible, and the locations illustrated in Figs. 9 and 10 are exemplary only.
    [0084] In still other examples, cells 112 can be formed from two separate pieces of material that are connected to leaves 118, 120. Fig. 11 is an enlarged side elevation view of a cell 112 formed by two fins disconnected 114, 116. In this example, cell 112 may not be fully closed, since fins 114, 116 may not be directly connected, and leaves 118, 120 may form a portion of a front and rear wall of cells 112 Referring to Fig. 11, the upper fin 114 may have a first free end 349 operatively connected to the first front connecting member 142 and a second free end 351 extending downwardly beyond the first rear connecting member 146, forming a 357 ear or flap. Ear 357 can at least partially extend downwardly from the first rear connecting member 146 towards the second rear connecting member 146. Ear 357 can be at least partially parallel to a portion of the rear leaf 120 or it may be otherwise angled to extend downwardly towards the second front connecting member 148.
    [0085] The lower fin 116 can be substantially similar to the upper fin 114, but can be positioned in the opposite way. That is, the lower fin 116 may include two free ends 353, 355, with the first free end 353 extending upwardly from the second front connecting member 144 towards the first front connecting member 142. Thus, the lower fin 116 it may include an ear 352 or flap which may form a portion of a front wall of cell 112. The second free end 355 may be operatively connected to the rear leaf on the second rear connecting member 148.
    [0086] With reference to Fig. 11, the two ears 352, 357 of the fins 114, 116 can substantially form the rear and front walls of cell 112, as they substantially extend the entire length of the leaves 118, 120, between the first members connection 142, 146 and the second connection members 144, 148. In other words, there may be a minimum distance, if any, between the upper flap ear 357 114 and the second rear flap member 148 and the flap ear 353 bottom 116 and first front connecting member 142. Ears 352, 357 may be at least partially a rigid material or may include a component, such as fibers or pressure-sensitive adhesive that can provide additional stiffness to allow ears 352 , 357 support themselves and maintain the desired shape. Since the ears 352, 357 extend towards the opposite fin 114, 116, the cell 112 can be substantially closed by the fins 114, 116. However, in other cases, the ears 352, 357 may define a gap and end before the first front connecting member 142 or the second rear connecting member 148, respectively. In these cases, the cell 112 can be, at least partially, defined by the front and rear leaves 118, 120. That is, the front and rear leaves 118, 120 can form a portion of the front and rear walls of the cells. Light Admission Example
    [0087] In some examples, the cover 100 can be oriented to allow light to be admitted through the cracks 124 or spaces between the cells 112. Fig. 12A is a side elevation view of another example of the cover of Fig. 1A with an end cap removed from the front rail. Fig. 12B is a side elevation view of another example of the cover of Fig. 1A, as the cells move from open to closed. Fig. 12C is a side elevation view of another example of the cover of Fig. 1B with the end cap removed. With reference to Figs. 12A-12C, in these examples, panel 104 can extend outwardly from a rear side of roll 126. In these examples, back sheet 120 can support the top end of cells 112, while front sheet 118 can support the bottom end of cells 112.
    [0088] In the examples where the architectural opening can be a window, the orientation of the panel 104 to the roll 126, as shown in Figs. 12A-12C, allows light (for example, from the sun) to enter through the front leaf 118 through the crevices 124. Conversely, with brief reference to Figs. 2B and 2C, the light entering through the rear leaf 120 can be blocked from leaving through the front leaf 118 by the fins 114, 116. This is because, in the example illustrated in Figs. 2B and 2C, as the cells 112 are closed, the upper end of the cells 112 can be operationally connected to the front leaf 118, such that cells 112 extend from the front leaf 118 downward towards the back leaf 120. In that sense , the light entering the panel 104 through the backsheet 120 can find the material of the cell 112 for one or more cells 112, which, as discussed in relation to Fig. 4B, can diffuse the light.
    [0089] However, with reference to Figs. 12A-12C, as the roll 126 is driven to close the cells 112, the back sheet 120 can be vertically displaced relative to the front sheet 118. As this occurs, the inner volume of the cells 112 decreases in size, as shown in Fig. 12B. The ends of each of the fins 114, 116 connected to the backsheet are moved upwards relative to the front sheet 118, and the fins 114, 116 extend downwards from the backsheet 120 to connect with the front sheet 118 ( opposite to the example shown in Figs. 2A-2C). This orientation of the fins allows light from a light source (such as the sun) to be transmitted through the crevices 124 without being substantially blocked.
    [0090] When panel 104 extends from the rear side of the roll, as shown in Figs. 12A-12C, cells 112 can allow light through panel 104 even when they transition from an open to a closed position. Although light can be admitted through the crevices 124, as cells 112 transition to the closed position, the fin material can provide privacy. For example, in some implementations, the front and rear sheets may be of translucent material, while the fins 114, 116 may be of a non-translucent or less translucent material. once cells 112 are closed, fins 114, 116 can be oriented vertically to reduce visibility through panel 104. Due to the orientation of the upper ends of cells 112, cells 112 can still allow light to be transmitted through the cracks 124. Thus, in a partially closed position, privacy can be improved compared to an open position, but the amount of light transmitted through panel 104 can be substantially the same or only slightly attenuated.
    [0091] In cases where more light may be desired to be admitted through panel 104, panel 104 can be oriented, such that the back sheet 120 can increase vertically in relation to the front sheet 118 to close cells 112. This orientation and Cell transition can allow light to be transmitted through the crevices 124 defined between cells 112, but it can still provide privacy, since the fins can block (or obscure) visibility through panel 104. Conclusion
    [0092] The previous description has wide application. For example, while the examples disclosed in this document may focus on the coverings for architectural openings, it should be appreciated that the concepts disclosed here may apply equally to other devices or devices, where variation in light transmittivity may be desired. Similarly, although coverage can be discussed in relation to a loop control cable, the devices and techniques disclosed in this document are equally applicable to other types of control cables or operating elements. In this sense, the discussion of any modality is only intended to be exemplary and is not intended to suggest that the scope of the disclosure, including the claims, is limited to these examples.
    [0093] All directional references (for example, proximal, distal, upper, lower, up, down, left, right, lateral, longitudinal, frontal, posterior, upper, lower, above, below, vertical, horizontal, radial , axial, clockwise and counterclockwise) are used for identification purposes only to assist the reader's understanding of this disclosure and do not create limitations, particularly with regard to the position, orientation or use of this disclosure.
