CROSS REFERENCE WITH RELATED REQUESTS
[001] This claim claims the benefit under 35 U.S.C. 119 (e) of U.S. Provisional Application No. 61 / 528,028, filed on August 26, 2011, which is hereby incorporated by reference here in its entirety. FIELD
[002] The present invention relates, in general, to covers for architectural openings and, more specifically, for cellular covers for architectural openings. BACKGROUND
[003] Covers for architectural openings, such as windows, doors, arcades and so on, have taken various forms for many years with some of these covers being retractable in nature so as to be movable between an extended position through the opening and a retracted position adjacent to one or more sides of the opening.
[004] More recently, retractable covers have been made in a cellular format. The cells in such covers are typically elongated tubes or cells that extend laterally through an opening. When the cover is open and extended through the opening of a window, the cells themselves are expanded, but when the cover is retracted, the cells close, so that each cell is stacked with the adjacent cell and collectively they are stacked together in a small space. SUMMARY
[005] Examples of the revelation include a cover for an architectural opening. The cover includes a cell panel having at least two cell units or rows stacked on top of each other. The cover also includes a first light-absorbing element positioned at an interface between the at least two cell units. The first light absorbing element can absorb substantially all wavelengths of visible light. Each cell unit can include an outer cell and an inner cell at least partially received within the outer cell. At least a portion of the outer surface of the inner cell may be exposed at the interface, such that the outer cell of another cell unit is positioned adjacent to the exposed portion of the inner cell. The first light-absorbing element can be positioned in the inner or outer cell. In one configuration, the first light-absorbing element is positioned on an outer surface of the exposed inner cell at an interface between adjacent cell units. The cover may further include a second light-absorbing element positioned on an opposite side of the interface of the first light-absorbing element.
[006] Other examples of the revelation include a cell panel to cover an architectural opening. The cell panel includes a first cell row and a second cell row operatively connected to the first cell row. The first cell row includes a first outer cell and a first inner cell at least partially received within the first outer cell. Similarly, the second cell row includes a second outer cell and a second inner cell at least partially received within the second outer cell. The first inner cell and the second inner cell can be made of a light-absorbing material. The cell panel also includes a first light-absorbing element positioned at an interface between the first cell row and the second cell row. The first light-absorbing element can be positioned on an outer surface of the second inner cell, and the first outer cell can define a gap through which the first light-absorbing element is exposed. Additionally or alternatively, the first light absorbing element can be positioned adjacent a first longitudinal edge of the first inner cell. In some configurations, the cell panel includes a third cell row operatively connected to the second cell row and a second light absorbing element positioned adjacent an interface between the second cell row and the third cell row. In these configurations, the first and second light-absorbing elements may have different widths. For example, the second light-absorbing element may have a smaller width than the first light-absorbing element.
[007] Still other examples of the revelation include a cover for an architectural opening. The cover includes a main rail, a cell panel and a bottom rail. The cell panel is operatively connected to the main rail and includes at least two cell units. Each cell unit of the panel includes an external cell and an internal cell at least partially received within the external cell. The cell panel further includes a first light-absorbing element positioned at an interface between the at least two cell units. In addition, the bottom rail is operatively connected at an opposite end of the main rail cell panel and moves vertically as the cover moves between an extended position and a retracted position. The first light-absorbing element can be embedded in at least one of the inner or outer cell and absorb substantially the entire wavelength of visible light. The first light-absorbing element can be dyed Mylar which absorbs substantially the entire wavelength of light. In some configurations, at least a portion of the outer surface of the inner cell may be exposed at an interface between adjacent cell units, such that the outer cell of another cell unit is positioned adjacent to the inner cell. In these configurations, the first light-absorbing element can be positioned in the inner cell and the element can also be positioned in the portion of the outer surface of the inner cell that is exposed at the interface.

[0028] A cell cover typically includes a plurality of vertically aligned elongated cells, which extend laterally, which can be closed transversely which are adhered longitudinally to adjacent upper and lower cells to form a vertical cell stack. The cross-section of each cell can take on numerous shapes, such as hexagonal, octagonal or their variations. Although such covers using cells that can be closed transversely are typically oriented, so that the cells extend laterally or horizontally, panels of such material can also be oriented so that the cells extend vertically or at an angle between the horizontal and vertical .
[0029] In some modalities here, a cell shutter is revealed. The cell cover panels are generally formed by assembling each cell of a cell unit from one or more strips of folded, curved or creased material along lines that extend longitudinally along the length of the material. Each formed cell is then attached along an upper attachment line to an adjacent positioned cell, but above the cell. The cell is also generally attached along a lower attachment line to an adjacent, but below the cell. In this way, a panel of stacked cells is formed.
[0030] Cell units are attached along the attachment lines (top and bottom) by a thin layer of adhesive having adjustable widths to securely connect cells in adjacent cells above and below to form the panel. Typically, both the outer and inner cells are made of a braided, non-braided or mesh material. The non-woven material can include natural or synthetic fibers and a resin to bond the fibers.
[0017] When connecting cells, the light permeability of the roof can be affected, since the light may be able to cross the connecting lines between each adjacent upper and lower cell. This can prevent the covering from blocking light completely (which may be desired in some cases), as well as may adversely affect the insulating qualities of the covering.
[0018] To substantially prevent or significantly reduce the passage of light through the connecting lines between each adjacent upper and lower cell, a light-absorbing element is positioned at the interface between the cells. The light-absorbing element is formed in a line that extends along the length of a cell in the interface regions between adjacent cells. The light-absorbing element may be continuous or segmented, may be linear or curved, may have varying widths and may have varying thicknesses. The light-absorbing element can be formed as an integral part of a cell or it can be a separate component attached to the cell. For example, the light-absorbing element may be a dye applied to the surface of, or embedded in, a strip of the material that forms the cell. Additionally or alternatively, the light-absorbing element may be a separate piece of material, such as a thin layer of plastic having light-absorbing qualities, attached to a cell surface. The light-absorbing element can be of various colors, including dark colors, depending on the desired light absorption. Furthermore, the light-absorbing element can be positioned in various locations where light infiltration can occur between adjacent cells, such as between adjacent cells, between internal and external cells, or both. In this way, light that can pass through the back side or path of a cell panel at the connection interface between cells can be absorbed by the light absorbing element instead of being transmitted to the front or environment side of the cell panel. Description of the figures
[0019] With reference to figures 1A and 1B, a cell panel 16 includes a plurality of cell units 22. Each cell unit 22 is operatively connected in at least one adjacent cell unit 22. Cell units 22 are attached along attachment lines or interface regions. The combination of cell units 22 forms cell panel 16. Each cell unit 22 can include an interior volume (single cell), two interior volumes (double cell) defined by an outer cell 24 and an inner cell 26 or more interior volumes in some settings. If the cell unit 22 is a double cell, the inner cell 26 can be substantially received within the outer cell 24. The two cells 24, 26 can be joined operatively (for example, via adhesive, stitching or other fasteners). The two cells 24, 26 form a single row or cell unit 22. At or near the connection or interface location of each cell unit 22, either or both the outer cell 24 and the inner cell 26 may include an absorption element. light. The light-absorbing element can be positioned adjacent to or at the connection point or interface between cells 24, 26 and / or cell units 22.
[0020] Fig. 1A is an isometric view of a roof 10 for an architectural opening in an extended position. Fig. 1B is an isometric view of the cover 10 in a retracted position. The cover 10 can include a main rail 12, a bottom or end rail 14 and a flexible cell panel 16 interconnecting the main rail 12 and the bottom rail 14. Cover 10 can be moved from the extended position shown in Fig. 1A to the position retract shown in Fig. 1B operating a control cord 18 having a tassel 20 located at a free end of the control cord 18. Control cord 18 can be connected to a lifting mechanism (such as lifting cords, not shown) . The lifting mechanism can extend through the panel 16 from the main rail 12 to the lower rail 14 and is operative to lift the lower rail 14 towards the main rail 12. The cover 10 may include a lanyard lock (not shown) inside the main rail 12 to secure the control cord 18 to keep the panel 16 in a desired position between fully extended and fully retracted. To extend the cover 10, the tassel 20 can rise, providing extra length for the lifting mechanism and the bottom rail 14 (through gravity) can fall. In other examples, cover 10 may include alternate control mechanisms, such as an automatic or motorized system, pulley system and so on.
[0021] With reference also to figures 1A and 1B, panel 16 includes a plurality of cell units 22 or rows. Each cell unit 22 extends horizontally or laterally across the width of the panel 16 and is vertically aligned with each other cell unit 22. Each cell unit 22 is operatively connected along its length in immediately adjacent upper and lower cell units 22 (described in more details below). In addition, each cell unit 22 can be closed transversely, such that when the cover 10 is retracted, the cell units 22 reduce in height and stack. For example, the cross-sectional area of each cell unit 22 taken at a right angle to the length of the panel 16 closes in a desired manner to allow for stacking.
[0022] With reference to figures 2B through 6 (Fig. 2A is cited below), each cell unit 22 may include an outer cell 24 and an inner cell 26 at least partially received within the outer cell 24. The outer cell 24 it can be formed of a long, narrow strip of material having generally parallel longitudinal edges 28. The strip is generally curved around lines of curvature that extend along the length of the strip to form a generally tubular structure. When the outer cell 24 is formed in the form of the hollow tubular cell, the edges 28 can be positioned substantially adjacent, but separated from one another to define a gap 29. In these examples, a portion of the inner cell 26 (for example, the top wall internal cell 26) can be exposed through gap 29.
[0023] In other examples, the edges 28 can be positioned directly adjacent (including touching) or even overlapping, so that there can be substantially no gap between each edge 28, see, for example, Fig. 5C. As the outer cell 24 can be formed from a single strip of material, the bottom 36 of the cell 24, which can be positioned on the opposite side of the edges 28, can be substantially continuous with no gap formed. The edges 28 of the outer cell 24 can define an upper wall 42 of the cell 24, so that each cell can have an upper wall 42, a lower wall 36 and opposite side walls 30. Each opposite side wall can define an external crease 34.
[0024] Still with reference to figures 2B through 6, the outer cell 24 may include upper side walls 30 moving downward and out of the edges 28. The inner surface 33 of the side walls 30 may face the inner cell 26 and the outer surface 35 of the side walls 30 can face the architectural or ambient opening. The longitudinal external crease 34 can be spaced substantially equal to the edges 28 and extend coextensively with respect to each other. Each crease 34 can be at least partially pointed and can produce a curve or fold line along the length of the outer cell 24. When the cell panel 16 is retracted and the cell closes for stacking, the side walls of the outer cell 24 fold inwards. along the crease 34. For example, the outer cell 24 can close in the crease line 34 when the bottom rail 14 retracts the cell panel 16. Below the crease line 34, the material that forms the outer cells 24 transits to form the walls lower sides 31 extending downward and away from the crease line 34 to form the bottom 36 of the outer cell 24.
[0025] As shown in figures 2B through 5 and 6, the inner cell 26 may have substantially the same cross-sectional shape and structural features as the outer cell 24. The inner cell 26, when the cell panel 16 is extended, engages the outer cell 24 in its upper and lower walls 42 and 36, thus forming a gap between adjacent side walls. The inner cell 26 may be formed of a strip of material which may include parallel edges 46 (see, for example, figures 7 to 9). In some implementations, the inner cell 26 can be inverted with respect to the outer cell 24. For example, the longitudinal edges 46 can be operatively connected to the bottom 36 of the outer cell 24 and a continuous upper wall 50 of the inner cell 26 can be connected to the edges 28 (forming the upper wall 42) of the outer cell 24. In addition, the inner cell 26 may include two upper side walls 54 that extend upward and outward from the edges 46 and two lower side walls 55 that extend below the creases 60 and pass to the bottom 57, which includes the longitudinal edges 46. Like the outer cell 24, the inner cell 26 closes along the creases 60 of the side wall when the cell panel 16 is retracted and the cells are stacked.
[0026] The side walls 54, 55 of the inner cell 26 can be positioned such that the outer surface of the side wall 54, 55 faces the outer cell 24 and the inner surface 21 faces inward toward the opposite side wall 54, 55. The upper side walls 54 pass to form the lower side walls 55 in the crease 60, and like the crease 34 in the outer cell 24, the crease 60 can allow the inner cell 26 to close when the cell panel 16 is retracted. The crease 60 of the inner cell 26 can be approximately aligned and coextensive with the crease 34 in the outer cell 24, such that the two cells 24, 26 can fold in longitudinal alignment with each other.
[0027] It should be noted that, in some implementations, either or both the inner cell 26 and the outer cell 24 may be formed, so that there may be no gap between the edges 28, 46 and, instead, only a seam where the edges touch or overlap. For example, Fig. 5C is an isometric view of the inner cell 26 formed without a gap between the edges 46. The outer cell 24 can be formed similarly, so that there may be no gap 29 between the edges 28. Alternatively, each one of the inner and outer cells 26, 24 can be formed of two or more strips of material and thus there may be gaps or seams formed at both the top and bottom of each respective cell.
[0028] Similarly, in some examples, the shape of the cross section of outer cell 24 and inner cell 26 can be varied from one another. For example, the inner cell 26 may have a circular cross section while the outer cell 24 may have a hexagonal cross section.
[0029] With reference also to figures 2B to 5 and 6, the outer cell 24 and the inner cell 26 may have a similar shape, although the inner cell 26 may be smaller than the outer cell 24. The two cells 24, 26 they can provide insulation, since each cell 24, 26 can capture air; thus, creating air pockets between a first side of the cell panel 16 and a second side of the cell panel 16. The two cells 24, 26 can be of substantially any shape, but each can generally define a volume. The volume defined by each cell 24, 26 can generally include at least two openings, for example, one on each side of the cell unit 22 on each side of the cover 10. The defined volume, as described above, can function to capture air from to provide insulation. In addition, when cell panel 16 is retracted, the volume for each cell 24, 26 may decrease as cell unit 22 closes transversely.
[0030] Additionally, the two cells 24, 26 can cooperate to prevent light from being transmitted through the cell panel 16. For example, either or both the outer cell 24 and the inner cell 26 may include blocking or reflecting materials from the visible wavelength. In one example, the inner cell 26 can be made of a light blocking material (e.g., Mylar) and the outer cell 24 can be made of another material (either translucent or opaque). The material can be a knitted, braided or non-woven material or it can be a fabric and can also be made of artificial, natural material or a combination of materials. In this example, the cell panel 16 can have an improved aesthetic appearance, while still providing the light blocking functions. In addition, the two cells 24, 26 can also produce sound wave insulation since the sound wavelengths can be reduced as from a first side of panel 16 to a second side of panel 16. It should be noted that other materials are possible for cells 24, 26 and the materials listed here are examples only.
[0031] With reference to figures 2A to 5 and 6 to 9, the outer cell 24 and the inner cell 26 can be operatively joined in several ways. The inner cell 26 and the outer cell 24 can be joined by adhesive 62 positioned on an outer surface of the upper wall 50 of the inner cell 26. In some implementations, there may be a line of adhesive 62 for each edge 28 of the outer cell 24. In addition, the two cells 24, 26 can be joined in a second location. The inner cell 26 may include adhesive 66 positioned along an outer bottom surface of the edges 46. As with adhesive 62, there may be two lines of adhesive 66 for each edge 46 of the inner cell 26.
[0032] The first cell unit 22A and the second cell unit 22B can be connected on an interface 48, as shown in figures 2B and 3, such that an upper surface of the first cell unit 22A can be aligned and positioned adjacent to a lower surface of the second cell unit 22B. Cell units 22A, 22B can be operatively joined via adhesive lines 64 positioned on an upper outer surface of each outer cell 24. It should be noted that the connection line between cell units 22A, 22B may include more than one line of adhesive 64. Together, the lines of adhesive 64 can form a region of linear connection along the length of the cell units 22A, 22B.
[0033] With reference to Fig. 2A, in some cell panels where each cell is made of material or is otherwise modeled to at least partially block the passage of light through them, the light may escape through the connection locations 48 between cell rows, forming a strip of light between the cells when viewed from the front or from the cell environment. For example, light from a rear or ambient side of the cell panel can be transmitted or reflected through adhesive 64 or through the material that forms the cells (if material without blocking light) or a combination of both. Streaks or streaks of light can occur in various aspect ratios of the adhesive. As shown in Fig. 2A, light can be transmitted through connection locations 48 in several directions, since adhesive 64 (or another connection mechanism) can partially refract light. The scattering of light at the junction of two adjacent cells may be due to the cell material, such as a tissue, having an uneven surface profile, the opening and / or porosity of the material and / or any reflective surfaces associated with the cells.
[0034] In these cell panels, even though the outer cell and / or the inner cell may include light-reflecting or non-light transmitting material, light can thus be transmitted through the panel. The escape of light through the connection location between cells passes through or around the adhesive used to join adjacent cells. In one example, this causes streaks of light to be seen between cells when in a darkened room with a cell shutter having blackout material in the cells.
[0035] With reference to figures 2B to 9, the cell unit 22 may include a light absorbing element 70 to block or absorb light, so that the light passing between adjacent cells is reduced or eliminated. This element 70, thus, can reduce or eliminate the light band problem. For example, a black list can be associated with an interface 48 and absorb substantially all of the light scattered in the middle of adjacent cells. The cell unit 22 can include one or more light absorbing elements 70 and each light absorbing element 70 can be positioned at various locations in either or both cells 24, 26. In one example, a printed black list or strip is positioned in the inner cell 26. The position of the light absorbing element 70 can be determined based on the locations of the adhesive connecting the cell units 22A, 22B, as well as the material type of the outer cell 24. For example, if the outer cell 24 is made of light-transmitting material, the inner cell 26 may include the light absorbing element 70, although the light absorbing element may be partially covered by the outer cell 24. This is because the light absorbing element 70 can absorb any light that may pass through the outer cell 24, as well as the light that passes through the connection locations between the cell units 22A, 22B.
[0036] The light-absorbing element 70 absorbs a sufficient amount of visible light that would normally pass through the gap between adjacent cells. The light-absorbing element can effectively absorb enough light on its own to largely minimize the effect of light streaking between adjacent cells or it can work in conjunction with the other structural features in the connection region (the adhesive strips, the cell material) to minimize or largely eliminate the strip of light between adjacent cells. Thus, the light that passes through or escapes between cells through the connection region to cause the strip of light to be absorbed or otherwise blocked by the light absorbing element 70 alone or in combination with the other cell structure in the vicinity of the region of connection. In some examples, the light absorbing element 70 is not a structural part of the interface 48 between adjacent cell units 22. In other words, in some examples, the light-absorbing element 70 does not join adjacent cell units 22 or transfers charges through an interface 48. In this way, the light-absorbing element can be distinct from the joining or fixing mechanism or device used to connect or dock a cell unit to an adjacent cell unit. In some examples, the light absorbing element 70 is a structural part of the interface 48 between adjacent cell units 22. In some instances, the adhesive used to connect cells 24, 26, or cell units 22 can be colored with a dye, such as a black dye, and function as a light-absorbing element, in addition to at least partially trapping the cells or portions of cells. Where colored adhesive is used as a light-absorbing element as well, the adhesive can be positioned in locations as shown and described here and / or can be additionally positioned where the separate light-absorbing elements are located.
[0037] Still with reference to figures 2B to 9, the light absorbing element 70 can be a black material, such as an ink or dye, or it can be a separate piece or pieces of laminated material firmly joined in the cell material and positioned at the interface of the connection region between cell units 22A and 22B. In one example, the light-absorbing element 70 may be a black colored dye applied to the strip of material that forms the inner cell 26 (see, for example, figures 7 to 9). The light absorbing element 70 can also be positioned on the strip of material that forms the outer cell 24 at the appropriate locations. An example of a suitable dye or ink is a black ink, FAB-PX00, Fabrasflex Black FR sold by Tokyo Ink, and is applied to the material strip in a layer having a thickness of approximately 0.08 mils, or approximately 2.1 microns . An example of the light absorbing element 70 being a separate piece of laminated material is a thin layer of dark colored plastic having absorbent qualities of visible light and sufficiently joined in the same or similar locations as the ink is applied to the strip of cell material and sufficiently secure to provide adequate support for the adhesives used to join adjacent cells. In this way, the light that can pass through a first side of the cell panel 16 at the connection interface 48 between cell units 22 can be absorbed by the light absorbing element 70 and may not be transmitted to the other side of the cell panel 16.
[0038] In other examples, the light absorbing element 70 can be other dark colors, such as, but not limited to, brown, gray, navy blue, dark blue, dark brown or dark green. In addition, each cell 24, 26 can include multiple light absorbing elements 70 positioned at various locations where light infiltration can occur.
[0039] With particular reference to Fig. 2B, the cell panel 16 includes a light absorbing element 70, which substantially prevents or significantly reduces the infiltration, escape, of the light, or that is otherwise transmitted through the connection locations 48 or interfaces between rows of cell 22. As shown in Fig. 2B, light entering adhesive 64 or otherwise entering connection locations (for example, through the outer cell material) is highly absorbed and substantially prevented from traversing the interface 48 between cell units 22A, 22B adjacent to panel 16. Thus, depending on the material and dimensions of cell panel 16, cell panel 16 may be able to substantially prevent any light transmission through it. This can allow cell panel 16 to be used to create “dark rooms” and other areas where light may not be desired. Additionally, cell panel 16 can offer more thermal insulation properties, since less light can be transmitted through panel 16 to heat a room. However, as the cell panel 16 can be extended and retracted, the light transmitted through a particular architectural opening can vary from approximately 0 percent to approximately 100 percent.
[0040] Cell panel 16 in Fig. 2B includes a lower cell unit 22A and an upper cell unit 22B connected together by a pair of longitudinally separated adhesive lines 64. Each cell unit 22A, 22B includes an inner cell 26 and an outer cell 24 joined with additional adhesive lines 62, 66. In particular, two laterally separated, longitudinally extended adhesive lines 62 connect corresponding upper walls 42, 50 of the outer cells and internal 24, 26, respectively. Similarly, two lines of adhesive 66 laterally separated longitudinally extended connect the corresponding lower walls 36, 57 of the outer and inner cells 24, 26, respectively.
[0041] Each inner cell 26 in Fig. 2B has a continuous top wall 50 and a discontinuous bottom wall 57, while each external cell 24 has a discontinuous top wall 42 and a continuous bottom wall 36. Thus, the adhesive lines 62 are aligned with the longitudinal edges 28 of the discontinuous top wall 42, extend laterally outward from the edges 28 and are arranged between the corresponding top walls 42, 50. Similarly, the adhesive lines 66 are aligned with the longitudinal edges 46 of the bottom wall discontinuous 57, extend laterally out of the edges 46 and are arranged between the corresponding lower walls 36, 57.
[0042] The adhesive lines 62, 66 can be symmetrical around a horizontal plane dividing the interface 48 between the upper and lower cell units 22A, 22B. In addition, adhesive lines 62, 66 can be symmetrical around a vertical plane dividing interface 48 between opposite sides of panel 16. Within interface region 48, adhesive lines 62, 66 can be positioned laterally inward. , or between, the adhesive lines 64. As shown in Fig. 2B, a gap 29 is formed laterally between the longitudinal edges 28 and the adhesive lines 62. Similarly, a gap 59 is formed laterally between the longitudinal edges 46 and the adhesive lines 66. Gaps 29, 59 can be opposed within interface 48.
[0043] Still with reference to Fig. 2B, multiple light absorbing elements 70A, 70B are positioned at the interface 48 between adjacent cell units 22A, 22B. A first light absorbing element 70A is associated with the lower cell unit 22A and is generally positioned in a lower portion of an interior space 63 of interface 48. More specifically, the first light absorbing element 70A is positioned on the upper wall 50 of the lower cell unit 22A in span 29 and extends laterally across the entire width of span 29. The first light absorbing element 70A is approximately the same height as each line of adhesive 62 and is lowered when compared to the upper wall 42 of the cell external 24. In an alternative example, as shown in Fig. 2C, the first light absorbing element 70A can be embedded and / or integral with the cell material and be coextensive in height with the upper wall 50 of the internal cell 26. In an alternative example, as shown in Fig. 2C, the second light-absorbing element 70B can be embedded and / or integral with the cell material and be coextensive in height with the bottom wall 36 of the outer cell 24. In addition, the light-absorbing element can be embedded in only a portion of the height (layer thickness) of the cell material. Referring again to Fig. 2B, the width of the first light absorbing element 70A is greater than its height. In one implementation, the first light absorbing element 70A can have an aspect ratio of at least 5: 1. The full width of the outer and / or inner cells 24, 26 can be printed with, colored with, or overlaid with a dark color, such as black, which acts as a light-absorbing element. The thickness of the printed area or light absorbing element 70 can be thin and, thus, the aspect ratio of the light absorbing element 70 can be relatively large. For example, in some examples, an aspect ratio of the light absorbing element 70 is between approximately 320: 1 and approximately 50,000: 1.
[0044] As shown in Fig. 2B, the first light absorbing element 70A is exposed to the interior space 63 of the interface 48 and is centrally located on the upper wall 50 of the inner cell 26, laterally equidistant between the adhesive lines 62, 64 and 66. At this location, the first light-absorbing element 70A absorbs light that is refracted or directed downward from the various resources associated with interface region 48, including adhesive lines 62, 64, 66, outer cells 24 and inner cells 26 (in configurations where outer cell 24 of the lower and / or upper cell units 22A, 22B is light permeable). In Fig. 2B, the light was refracted from the adhesive 64 and / or reflected from the lower wall 36 to the first light absorbing element 70A, as represented by the arrows arranged inside the interface 48. The first light absorbing element 70A absorbs the light to substantially reduce or eliminate light transmission through the interface 48.
[0045] In Fig. 2B, a second light-absorbing element 70B is associated with the upper cell unit 22B and is generally positioned in an upper portion of the interior space 63 of interface 48. The second light-absorbing element 70B is positioned above the lower wall 36 of outer cell 24 of upper cell unit 22B to absorb any light that passes through outer cell 24 of upper cell unit 22B (i.e., outer cell 24 of upper cell unit 22B is light permeable in Fig. 2B). More specifically, the second light-absorbing element 70B is connected to the bottom wall 36 and is positioned in the gap 59 and extends laterally across the entire width of the gap 59. The second light-absorbing element 70B is approximately the same height as each line adhesive 66 and thus is lowered as compared to the bottom wall 57 of the inner cell 26. In an alternative example, as shown in Fig. 2C, the second light absorbing element 70B can be embedded in the cell material and be coextensive in height with the bottom wall 36 of outer cell 24. With reference again to Fig. 2B, the width of the second light-absorbing element 70B is greater than its height. In one implementation, the second light-absorbing element 70B can have an aspect ratio of at least 5: 1. The vertical cross section of the interface 48, moving upward along a vertical plane dividing the cell units 22A, 22B includes the upper wall 50 of the inner cell 26 of the lower cell unit 22A, the first light absorbing element 70A, a space 63, a lower wall 36 of the outer cell 24 of the upper cell unit 22B and the second light absorbing element 70B.
[0046] As shown in Fig. 2B, the second light-absorbing element 70B is located centrally on the bottom wall 36 of the outer cell 24, laterally equidistant between the adhesive lines 62, 64 and 66. In this location, the second absorbent element of 70B light absorbs light that is refracted or directed upward from the various features associated with interface region 48, including adhesive lines 62, 64, 66, outer cells 24 and inner cells 26 (in configurations where the outer cell 24 of the lower and / or upper cell units 22A, 22B is light permeable). In Fig. 2B, the second light absorbing element 70B is laterally aligned with, but vertically separated from, the first light absorbing element 70A.
[0047] In operation, the light approaching the interface region 48 between adjacent cell units 22A, 22B generally encounters the outer cells 24 of cell units 22A, 22B, adhesive 64 or both. If outer cells 24 are impermeable to light, outer cells 24 reflect rays of light, some of which can find adhesive 64. If outer cells 24 are permeable to light, some of the rays of light pass through outer cells 24 and they can initially find at least one of the interface components 48, which include adhesive lines 62, 64, 66, portions of the outer cells 24, portions of the inner cells 26 and the light absorbing element (s) 70.
[0048] In Fig. 2B, the light absorbing elements 70A, 70B are positioned inside the adhesive lines 62, 64, 66 and, thus, the incoming light rays must pass through at least one of the adhesive lines 62, 64 , 66 or the outer cell 24 before reaching the light absorbing elements 70A, 70B. Each line of adhesive 62, 64, 66 and the outer cell 24, if permeable to light, generally absorb and / or reflect a portion of the incoming light rays. Thus, these absorbed or reflected rays of light are not transmitted through interface 48 to the other side of the cell panel 16. In other words, only a portion of the light that approaches interface 48 on one side of the panel is transmitted into space interior 63 of interface 48.
[0049] Adhesive lines 62, 64, 66 and outer cell 24 generally do not include polished, mirrored or specular surfaces, but preferably have many uneven surfaces or small outer facets, some of which may be microscopic. Thus, the rays of light that pass through the adhesive 62, 64, 66 or the outer cell 24 generally leave the surface in a diffuse pattern. Most, if not all, of the diffused light rays encounter and are absorbed by the light absorbing elements 70A, 70B, which are selectively positioned at the bottom and top of the interface 48, respectively. A small percentage of the light rays can pass laterally through the light absorbing elements 70A, 70B. However, these rays of light must pass through at least one additional line of adhesive 62, 64, 66 or outer cell 24 before leaving interface 48 on the other side of panel 16. Similar to the previous discussion, the additional lines of adhesive 62, 64 , 66 and outer cell 24 absorb and reflect a portion of these rays of light. Thus, any amount of light passing through the additional lines of adhesive 62, 64, 66 or outer cell 24 to the other side of the panel 16 is generally tiny and inconspicuous. In other words, the configuration of the adhesive lines 62, 64, 66, the outer cell 24, the light absorbing elements 70A, 70B or a combination thereof substantially eliminates or significantly reduces any amount of light passing through the interface 48. Generally speaking , no amount of light perceptible to man is transmitted through interface 48 from a first side, which can be the rear side or the path, to a second side, which can be the front or ambient side, of panel 16 , since most, if not all, of the light passing into the interior space 63 of the interface 48 is absorbed by the light absorbing element (s) 70.
[0050] As should be seen, although light absorbing elements 70A, 70B are shown to be a separate component fixed to a cell unit 22A, 22B, light absorbing elements 70A, 70B can be integral with the wall of a unit cell 22A, 22B. For example, as previously described, the light absorbing elements 70A, 70B can be a dye that is applied to a portion of the material of a cell unit 22A, 22B associated with interface 48. In addition, it should be checked, although two absorbent elements 70A, 70B are shown, that other numbers of light absorbing elements can be used. Examples include only one light-absorbing element or more than two light-absorbing elements per interface 48.
[0051] Referring now to Fig. 3, another exemplary interface 48 between adjacent cellular panels 22A, 22B is shown. In general, in this example, the adhesive lines 62, 64, 66 are positioned at approximately the same location as in the example shown in Fig. 2B. However, the aspect ratio of the adhesive lines 64 outwardly is changed. More specifically, the aspect ratio of the adhesive lines 64 in Fig. 3 is approximately 3: 1, while the aspect ratio of the adhesive lines 64 in Fig. 2B is approximately 1: 1. In some examples, the aspect ratio of the adhesive lines is between approximately 1: 1 and approximately 10: 1. In some examples, the aspect ratio of the adhesive lines is between approximately 1: 1 and approximately 5: 1 (ratio of width relative to height). In some examples, the aspect ratio of the adhesive lines is approximately 2: 1.
[0052] Similar to the example shown in Fig. 2B, in Fig. 3, multiple light absorbing elements 70A, 70B are positioned at the interface 48 between adjacent cell units 22A, 22B. A first light absorbing element 70A is centrally located on the upper wall 50 of the inner cell 26 of the lower cell unit 22A and is positioned below two lines of adhesive 62, which connect the upper wall 50 of the inner cell 26 to the upper wall 42 of the cell outer 24. The adhesive lines 62 are laterally separated from each other by a gap 29, and the light absorbing element 70A extends continuously below the entire width of each adhesive line 62 and through gap 29. In other words, the width of the first light absorbing element 70A is the aggregate of the width of the two lines of adhesive 62 and the width of the gap 29.
[0053] Still with reference to Fig. 3, a second light-absorbing element 70B is associated with the upper cell unit 22B. In particular, the second light-absorbing element 70B is positioned adjacent an edge 46 of the lower wall 57, below the lower wall 57 and above an adhesive line 66, which joins the lower walls 57, 36. In other words, the second light absorbing element 70B is positioned vertically between the lower wall 57 of the upper cell unit 22B and an adhesive line 66.
[0054] The second light-absorbing element 70B of Fig. 3 is laterally displaced from the center of the bottom wall 36 of the outer cell 24 to a side of the panel 16, which can be the rear side or the path of the panel 16. The second element light absorber 70B extends continuously across the entire width of the adhesive line 66. In other words, the width of the second light absorbent element 70B is approximately identical to the width of one of the adhesive lines 66.
[0055] In the configuration shown in Fig. 3, the first light-absorbing element 70A is positioned below the interior space 63 of the interface 48 and the second light-absorbing element 70B is positioned above the interior space 63 of the interface 48. The first element light absorber 70A in Fig. 3 has a wider width than the light absorbent element 70A in Fig. 2B and thus can absorb more light due at least in part to the larger surface area. The second light-absorbing element 70B in Fig. 3 is laterally moved from the center of the interface 48 to one side of the panel 16, so as to absorb the light transmitted from that side of the panel 16 before or after the light crosses an intermediate point of the interface 48. In addition, the positioning of the second light-absorbing element 70B adjacent to a longitudinal edge 46 uncovers the gap 59 located laterally between the opposite edges 46. In configurations where the outer cell 24 is permeable to light and the inner cell 26 is impermeable In the light, the gap 59 acts as an additional light prevention feature of the interface 48, since the light that passes through the gap 59 enters the inner cavity of the inner cell 26, where the light is absorbed or continuously reflected within the cavity, from that substantially preventing light from escaping from the inner cavity of the inner cell 26.
[0056] As still shown in figures 4A and 4B, the light absorbing element 70 can be positioned adjacent to or below the adhesive lines 62, 64, 66. This can help prevent light from being transmitted through or around the adhesive 62, 64, 66, since light can enter the adhesive lines 62, 64, 66, but can be absorbed by the light absorbing element 70. In figures 4A and 4B, the first light absorbing element 70A extends below of spatially separate adhesive lines 62 similar to Fig. 3. However, in contrast to Fig. 3, the first light absorbing element 70A shown in figures 4A and 4B extends laterally outward from below the adhesive lines 62 for each side of the panel to absolve or collect the light before the light meets the adhesive lines 62. The first light absorbing element 70A in figures 4A and 4B covers a substantial width of the upper wall 50 of the inner cell 26. For example, the first light absorbing element 70A cob re more than 50% of the width of the upper wall 50. Also shown in Fig. 4A, the second light-absorbing element 70B can be positioned below the adhesive line 66 and extend outwardly for the transition of the lower wall 57 into the lower side wall 55 of the inner cell 26. In other words, the second light absorbing element 70B has a width that extends along a lower wall 57 of the inner cell 26 between a longitudinal edge 46 and the transition point the lower side wall 55.
[0057] Although figures 2B, 3, 4A and 4B show several examples of where a light absorbing element 70 can be located, many other locations can also be effective in substantially preventing the transmission of light through an interface 48 of cell units 22A, 22B adjacent. With reference to figures 5 to 5C, in some implementations, the light absorbing element 70 can be positioned at adjacent locations or otherwise close to the interface or seam between cells 24, 26, as well as at the interface between cell units 22.
[0058] In one example and as shown in figures 5A and 5B, a first light absorbing element 70A can be positioned on an upper surface 51 of the upper wall 50 of the inner cell 26 and a second element 70B can be positioned along the edge lower longitudinal 46 of the inner cell 26 (see Fig. 5B). Thus, the inner cell 26 can include two separate light absorbing elements 70A, 70B with each light absorbing element 70A, 70B positioned at a different connection location between the outer cell 24 and the inner cell 26 and / or the first cell unit 22A and the second cell unit 22B. As further illustrated in Fig. 5, the first light absorbing element 70A is centrally located in the upper wall 50 of the inner cell 26 and extends laterally outward through the gap 29, below both spatially separate and lateral adhesive lines 62 outside the outer edge of each of the adhesive lines 62. The first light absorbing element 70A has a width that is a substantial portion of the entire width of the upper wall 50. The width of the first light absorbing element 70A can be at least 50% of the entire width of the upper wall 50. Also illustrated in Fig. 5, the second light absorbing element 70B is positioned below the adhesive line 66 and extends from the longitudinal edge 46 of the lower wall 57 through the entire width of the adhesive line 66 and laterally out of an outer edge of the adhesive line 66.
[0059] Fig 5C illustrated with the longitudinal edges 46 spaced directly close together (without a gap between them). The inner cell 26 of Fig. 5C includes a first light absorbing element 70A positioned on the upper wall 50 and a second light absorbing element 70B positioned on the lower wall 57. As illustrated, the first light absorbing element 70A is positioned centrally on the wall upper 50 approximately equidistant from the sides of the inner cell 26. The first light absorbing element 70A in Fig. 5C has a width that is approximately one third of the entire width of the upper wall 50. The second light absorbing element 70B is positioned on the wall bottom 57 and is laterally displaced from the first light absorbing element 70A. Although figures 5 to 5C show only a single cell, there may be another cell, as well as adjacent upper and lower cell units that work with the light absorbing elements 70A, 70B to absorb the light between the cell units and the cells.
[0060] As previously described, in some implementations, the light absorbing element 70 can be positioned in the outer cell 24. Fig. 6 is an isometric view of the first cell unit 22A and the second cell unit 22B operatively joined. The light-absorbing element 70 can be operatively connected to the outer surface of the outer cell 24 near one or both edges 28. Alternatively or additionally, in some cases, the light-absorbing element 70 can be positioned on the outer surface of the bottom wall 36 from outer cell 24 (as shown in cell unit 22B in Fig. 6B). Thus, the light absorbing element 70 can be positioned at a seam or interface location between the cell units 22. As illustrated in Fig. 6, the light absorbing element 70 extends laterally from the longitudinal edge 28 of the upper wall 42 of the cell outer 24 to the inner edge of the adhesive line 64. The light absorbing element 70 may extend below the adhesive line 64 and laterally outside the outer edge of the adhesive line 64 in some examples.
[0061] The light-absorbing element 70 can have varying widths which may depend on the particular configuration of cells 24, 26 and / or cell unit 22, as well as on the width, thickness and placement of the adhesive. For example, if the connection interface between cell units 22A, 22B has a greater amount of adhesive or additional seams, a wider light-absorbing element 70 may be needed in order to absorb appropriate amounts of light. In addition, in some examples, it may be desirable for the light absorbing element 70 to be smaller in width, so that it cannot be visible from a normal viewing angle by a user. This can be especially desirable in cases where the outer cell 24 can be formed of a lighter colored material, such that the color of the light absorbing element 70 can be visible through the outer cell 24. The light absorbing element 70 can extend just below the adhesive or it can extend laterally from under either or both sides of the adhesive.
[0062] In some implementations, the light absorbing element 70 can be incorporated into or into the material used to create the inner cell 26 and / or the outer cell 24. For example, figures 7 to 10 illustrate plan views of an inner cell unformed 26 including the light absorbing element 70. As described above, the inner cell 26 can be a light blocking or light reducing material, such as Mylar, polyurethane and polyolefins, and the light absorbing elements 70A, 70B may be blackened or dyed portions of the inner cell material 26. separate light absorbers 70A and 70B positioned in the unformed inner cell 26. As noted above, cells 24, 26 are made of long, narrow strips of folded, curved or creased along longitudinal lines. The strip of material 76 may have an overall width F and the light absorbing elements 70A, 70B may have widths G, H that are less than the width F of material 76. As briefly described above, the strip of material 76 may have a first color and the light absorbing element 70 can be a black-dyed portion of material 76.
[0063] Fig. 7 and a first example illustrating two light absorbing elements 70A and 70B
[0064] The first light absorbing element 70A can be positioned close to a middle or central line 77 of the strip of material 76, such that when the inner cell 26 is formed, the first light absorbing element 70A can be positioned on the external surface. the continuous upper wall 50 of the inner cell 26 (see Fig. 5). The first light absorbing element 70A can be slightly off center from the center line 77 of the material 76. For example, as shown in Fig. 7, the first light absorbing element 70A can end on a center line 77 of the width F of the material. 76. The adhesive lines 62 for cooperatively connecting the inner cell 26 to the outer cell 24 can be positioned on top of the light absorbing element 70, such that the light absorbing element 70 can extend beyond either side of the adhesive lines 62 In other examples, the adhesive lines 62 can be positioned off-center and adjacent to the light absorbing element 70.
[0065] The second light-absorbing element 70B can be positioned adjacent to one of the longitudinal edges 46 of the inner cell 26. For example, with reference to figures 5, 7 and 8A, the second light-absorbing element 70B can be positioned on the surface lower 53 of the inner cell 26 at or adjacent to the longitudinal edge 46. As with the first light absorbing element 70A, the adhesive lines 66 can be positioned on or adjacent to the second light absorbing element 70B. The second light-absorbing element 70B can be especially useful for absorbing the light that can enter through the material of the outer cell 24. As described above, in some implementations, the outer cell 24 may be a light transmitting material. In this implementation, the second light-absorbing element 70B can be at least partially covered from the interface 48 between cell units 22A, 22B (see figures 3 and 5) and still function to absorb light that could potentially be transmitted otherwise from one side from panel 16 to the other. This is because light could enter through the outer cell 24 and without the light absorbing element 70B it would be able to be transmitted through the top 30 of the outer cell 24 and through the interface 48. But with the second light absorbing element 70B, the light is absorbed before being transmitted via interface 48.
[0081] A third light-absorbing element 70C can be positioned adjacent to another of the longitudinal edges 46 of the inner cell 26. For example, with reference to both figures 7A and 9A, the third light-absorbing element 70C can be positioned on the surface bottom 53 of the inner cell 26 at or adjacent to the longitudinal edge 46. As with the first and second light absorbing elements 70A, 70B, the adhesive lines 66 can be positioned on or adjacent to the third light absorbing element 70C.
[0082] The widths of the first light-absorbing element 70A, the second light-absorbing element 70B and the third light-absorbing element 70C can be varied. For example, figures 7 and 7A illustrate the first light absorbing element 70A as having a width G, the second light absorbing element as having a width H and the third light absorbing element as having a width J. In this example, depending on of the material width F, the width G of the first light absorbing element can be approximately 1.27 cm (% inch), the width H of the second light absorbing element 70B can be approximately 0.71 cm (9/32 of a inch) and width J of the third light absorbing element 70C can be approximately 0.71 cm (9/32 of an inch) and width J of the third light absorbing element 70C can be approximately 0.40 cm (5/32 inch). Although different dimensions are possible, in some cases, the width of the first light absorbing element 70A can be approximately 1/6 of the width F of the material 76. In this example, the widths G, H, J of the light absorbing elements 70A, 70B , 70C can be made thinner, so that the user cannot substantially see the light absorbing elements 70A, 70B through normal viewing angles.
[0083] Figures 8 and 8A are another example of a strip of material 76 used to form inner cell 26 or outer cell 24. As shown in the example in figure 8, there may be a single light absorbing element 70 with a width K which can be approximately half the width F of the material 76. In this way, half of the outer surface of the inner cell 26 can include the light absorbing element 70A. Similarly, although not shown in figure 8, in some cases, the light absorbing element 70 can be positioned across the outer surface of the inner cell 26. In other words, the entire outer surface of the inner cell 26 can be dyed black. As shown in figure 8A, a second light-absorbing element 70B with a width J can be positioned adjacent to a longitudinal edge 46. In this example, more than half of the outer surface of the inner cell 26 is associated with a light-absorbing element 70 .
[0066] Figure 9 is another example of the light absorbing elements 70A, 70B. In this example, the widths of the light absorbing elements 70A, 70B can be substantially reduced. This can allow the material of the outer cell 24 to be lighter in color since the color of the light absorbing elements 70A, 70B can be dark, the larger widths can be visible through the outer cell 24. With a narrower width, elements 70A and 70B are less likely to be seen through a lighter material. In one example, the width F of the material can be approximately 7.62 cm (3 inches). The first light absorbing element 70A can have a width L which can be approximately 0.48 cm (3/16 of an inch) and the second light absorbing element 70B can have a width J which can be approximately 0.40 cm ( 5/32 of an inch). However, other dimensions are also applicable, depending on the width of the material 76 and / or the desired widths of the light absorbing elements 70A, 70B. In this example, the light absorbing elements 70A, 70B may be of substantially reduced width, but may still be able to substantially prevent the transmission of light from one side of the cell panel 16 to a second side of the cell panel 16. Fig. 9A includes a third light-absorbing element 70C having the same width J as the second light-absorbing element 70B. As shown, the second and third light-absorbing elements 70B, 70C are symmetrical around the center line 77. Although not shown in Fig. 9A, the first light-absorbing element 70A can be centered along the center line 77, from so that the center line delineates the strip of material 76 in two equal halves or longitudinal parts. Conclusion
[0067] The preceding description has wide application. For example, while the examples disclosed here may focus on the position or width of the light absorbing element, it should be noted that the concepts disclosed here can be applied equally to generally any position or width of the light absorbing element. Similarly, although the light-absorbing element has been discussed with respect to being a separate element, the devices and techniques are equally applicable in modalities where the inner cell or the outer cell is integrally formed with the light-absorbing element. For example, the light-absorbing material can be embedded in the cell-forming material strip (at the desired positional location) or can be covered by the entire thickness (at the right positional location) of the cell-forming material strip. In addition, the light-absorbing element may be formed of a separate piece of laminated material, such as a woven or nonwoven fabric made of natural or artificial material. The light-absorbing element of this type can be positioned and / or secured in desired locations by sewing, adhesive, fasteners or other types of fixation. Accordingly, the discussion of any modality is intended only to be explanatory and is not intended to suggest that the scope of the disclosure, including the claims, is limited to these examples. Also, although the materials used to form the cells in the examples described here are generally flexible material, it is considered that they can be rigid or semi-rigid or a combination and made of artificial or natural material or a combination of materials. All direction references (for example, proximal, distal, upper, lower, up, down, left, right, lateral, longitudinal, front, rear, top, bottom, above, below, vertical, horizontal, radial, axial , clockwise and counterclockwise) are only used for identification purposes to assist the reader's understanding of the present disclosure and not to create limitations, particularly as to the position, orientation or use of that disclosure. Connection references (for example, fixed, coupled, connected and joined) should be interpreted widely and may include intermediate members between a collection of elements and relative movement between the elements unless otherwise indicated. As such, the connection references do not necessarily suggest that two elements are directly connected and in fixed relation to each other. The drawings are for illustration purposes only and the relative dimensions, positions, order and sizes reflected in the drawings attached to them may vary.
