INCORPORATION BY REFERENCE
    [002] This application incorporates by reference in its entirety, as if completely described here, the matter disclosed in the following PCT application: PCT international patent application No. PCT / US2011 / 032624, filed on April 15, 2011, entitled “ A Process and System for Manufacturing a Roller Blind ”. FIELD
    [003] The present disclosure generally refers to covers for architectural openings, and, more specifically, retractable covers for architectural openings. FUNDAMENTALS
    [004] Coverings for architectural openings, such as windows, doors, arches and the like, have taken on numerous forms for many years. Initial forms of such coverings consisted primarily of draped fabric across the architectural opening, and in some cases, the fabric was not movable between extended and retracted positions in relation to the opening. Some newer versions of covers may include cellular blinds. Cellular blinds can include flexible tubes arranged horizontally that are stacked vertically to form a panel of tubes. In these blinds, the panel is retracted and extended by raising or lowering the lowest cell. As the lowest cell is lifted, it lifts the cells above it and flexes them on top of each other. As the lowest cell is lowered, the cells are pulled open. When in a stowed position, current cellular blinds are stored in a stacked configuration, that is, one cell on top of the other cells. This retracted configuration is required, as wrapping the cells around a roller tube can damage the cells and / or prevent the cells from opening. ABSTRACT
    [005] This disclosure includes a cover for architectural opening. The cover for architectural opening can include a support tube and a panel operatively connected to the support tube. The support tube can be configured to support the top or side panel of the architectural opening. The panel is configured to be wrapped around the support tube. The rotation of the support tube is controlled by activation cords that engage a drive mechanism, which, in turn, engages the support tube. The panel includes a backing sheet and at least one fin or batten operatively connected to the backing sheet. The fin or batten includes a first material operatively connected to a first side of the backing sheet and a support member operatively connected to the first material and configured to support the first material at a distance away from the backing sheet when the panel is in a position extended with respect to the support tube.
    [006] In some examples, the cover may include a first fin and a second fin. The first fin includes a first supporting member and a first fin material operatively connected to the first supporting member. The first fin material includes a first upper portion, a first medium portion, and a first lower edge. The first upper portion is operatively connected to the backing sheet adjacent to a first upper edge of the first fin material defining a first support, the first top portion extends downwardly adjacent to the backing sheet and, at a first inflection point, makes the transition away from the backing sheet to the first middle portion, the first middle portion makes the transition, at a second inflection point, to the first lower edge. The second fin includes a second support member and a second fin material operatively connected to the support member. The second fin material includes a second upper portion, a second medium portion, and a second lower edge. The second upper portion is operatively connected to the backing sheet adjacent to a second upper edge of the second fin material, defining a second support, the second top portion extends downwardly adjacent to the backing sheet and, at a third inflection point, makes the transition away from the backing sheet to the second middle portion, the second middle portion makes the transition, at a fourth point of inflection, to the second lower edge.
    [007] Other examples of the present disclosure may take the form of a method for fabricating a cover for an architectural opening. The method includes operatively connecting a fin material and a supporting member, wrapping the fin material and the supporting member around a support tube, heating the fin material and the supporting member so that the supporting member form a shape substantially the same as a shape of or corresponding to the support tube, to cool the fin material, the support member and the support tube.
    [008] Still other examples of the present disclosure can take the form of a blind for an architectural opening. The shutter includes a backing sheet, a first flap operatively connected to the backing sheet, and a second flap operatively connected to the backing sheet. The first fin includes a first fin material operatively connected, in a first location, to the backing sheet and a first supporting member operatively connected to the first fin material. The second fin includes a second fin material operatively connected, in a second location, to the backing sheet and operatively connected, in a third location, to the first fin material and a second support member operatively connected to the second fin material.

    [0023] The present disclosure generally refers to a panel to cover an architectural opening that can include one or more strips or fins that can form pseudocells operatively connected to one or both sides of a material or backing sheet. The panel or cover can be configured so that it can be retracted and expanded, and, when in the retracted position, the panel can be wrapped around a tube, bar, support rod or the like. This allows the panel to provide some of the benefits of cellular coverage (for example, insulation, aesthetic appeal) from the pseudocells, formed by the fins, while at the same time providing the benefits of non-cellular coverage (for example , hidden and compact storage). Specifically, having a stowed position that allows the panel to be stored around a support tube, the cover can be stored out of sight behind a main rail. This is beneficial since state-of-the-art cellular blinds are typically stored only in a stacked vertical position and thus would not be completely hidden out of sight on a main rail. Additionally, because the panel can be rolled over a support tube, it can be protected by a main rail or other dust member, sun damage (eg, fading), and so on. In addition, in some embodiments, the panel can be retracted to a stacked position, alternatively to be wrapped around a support tube; thus, the panel as described here may have the option of being either stacked or rolled when in the stowed position.
    [0024] Some modalities of the panel may include pseudocells formed by slats or fins that extend laterally and are positioned vertically in relation to each other. Each lath can be operatively connected to a backing sheet by one or more connection mechanisms. In such cases, the fins can define pseudocells. Pseudocells are defined by a combination of the backing sheet and the fin material of the respective fin. In some embodiments, each flap or batten can be operatively connected to the backing sheet so that a portion or upper free support can extend beyond a connection point between the flap and the backing sheet. This support can assist the fin to extend away from the backing sheet as the panel is extended. Each fin can form a shape generally of half a drop of water in cross section, and extend in length from one side to the other of the panel. Each of the battens or fins may include a support member that can be formed by heat in a particular shape. For example, the support member can be a thermoformable material that can become partially or substantially resilient after heating, and can retain a desired shape after cooling. The support member can be operatively connected to the fin or slat material (for example, fabric) and form an external fin cover, or an internal fin cover. However, in some modalities, the supporting member can be integrated with material forming each fin.
    [0025] The panel can be formed operatively by connecting the support member to a fin material and then wrapping both the fin material and the support member around a support tube, mandrel, or other forming member. The support tube, the fin material, and the support member can then be heated. As the components are heated, the support member can usually be reformed to generally adapt to the shape of the support tube. After cooling, the fin material assumes the shape of the support member where the two are engaged. Then, the tube and support panel can be installed over an architectural opening.
    [0026] It should be noted that modalities here can refer to a panel or blind to cover an architectural opening. However, the panels disclosed here can be used in several ways. For example, panels can be used as wall coverings, wallpaper, texture for walls, and so on. The Panel
    [0027] Fig. 1 is a front isometric view of a panel system 100. Fig. 2 is an enlarged isometric view of panel system 100 of Fig. 1. Fig. 3 is an exploded view of a panel system fin. 100 as shown in Fig. 2. Panel system 100 can include a main rail 102 or other support structure that can support a panel 106 and an end rail 104 over an architectural opening. A support tube or roller can be positioned on the main rail 102. The end rail 104 is operatively connected to an end edge of the panel 106, and provides a weight to help tension the panel when extended. Panel 106 is configured to provide a cover for an architectural opening, such as a window, arch, etc.
    [0028] Panel 106 can include fins 107 which can define plurality of pseudocells 108. For example, each of pseudocells 108 can be defined at least in part by a backing sheet 110, a fin material 112, and a member of support 114. The fin material 112 and the support sheet 110 operatively connected to each other to form a front side of the panel 106. In some embodiments, the fins 107 can be stacked directly on top of each other, and in other embodiments, the fins 107 can be spaced from each other, depending on the desired appearance and / or light transmittivity of panel 106. The fins or strips 107 extend laterally from side to side of panel 106. In other examples, fins 107 may extend vertically from side to side of panel 106.
    [0029] In addition to the fin material 112, as shown in Figs. 2 and 3, the fins 107 or slats may include a support member 114 which can be resilient in order to allow the fins 107 to form around a roller or support tube and propel themselves or are prone away from the foil. support 110 when panel 106 is extended. The fins can be considered to be “closed” where the backing sheet and the fin are positioned to be adjacent in close proximity to each other (either in contact or in partial contact) while on the roller in the stowed position. In the closing act, the supporting member may deviate from its curvature formed in a slight amount, in a large amount, or it may not deviate appreciably. Pseudocells 108 close when rolled up onto the roller or main tube because, in one example, the support member rolls up onto the tube in a diameter approximately equal to the established curvature of the support member. If the supporting member were quite rigid, it would remain in substantially the same shape, rolled or unrolled. The fins and thus the pseudocells would then be closed to the roller when rolled up, and opened by the curvature of the support members when the blind is unrolled or straightened. The curvature of the supporting members would correspond or approximately correspond to the curvature with which each was formed. Supporting member 114 will be discussed in more detail below. Briefly, the support member 114, which can be formed to determine the shape and height of the fins 107, and, as shown in Figs. 4-5, can have a first shape prior to formation and, as shown in Figs. 2 and 3, can have a second format after training. The training of support member 114 will be discussed in more detail below.
    [0030] Panel system 100 will now be discussed in more detail. Fig. 6A is a cross-sectional view of the panel system 100 taken along line 6A-6A in Fig. 1. Fig. 6B is an enlarged view of the fin material 112 operatively connected to the backing sheet 110. The fins 107 they are configured so that each fin 107 can extend outward and away from the backing sheet 110, as well as it can close and wrap in layers over the backing tube 116. A backing tube 116 (see Fig. 8) it can be supported within the main rail 102, so that the main rail 102 can substantially cover or hide all or a substantial portion of the support tube 116 and extend and retract the blind. Main rail 102 can include an opening through which panel 106 can extend. With brief reference to Fig. 8, the support tube 116 can be positioned inside the main rail 102 so that the panel 106 can be raised and lowered with respect to the main rail 102 through the opening. For example, as panel 106 is extended, support tube 116 will roll, unwinding panel 106, which can then pass through the opening beyond main rail 102. Similarly, when panel 106 is retracted, the support tube 116 will roll in an opposite direction, further wrapping panel 106 around support tube 116, retracting the panel through the opening. Alternatively or additionally, the terminal rail 104 can be raised towards the main rail 102 and the panel 106 can be stacked underneath instead of rolling around the support tube 116.
    [0031] With reference to Figs. 2 and 6A, the shape of the fins 107 and attachment to the backing sheet 110 can define the pseudocells 108 that each define an internal chamber 105 or empty space, which is expanded when the panel 106 is in the extended position and closed when in the stowed position (rolled around support tube 116 or stacked). For example, in the "closed" position, the backing sheet can be pressed against a length of the fin 107 and, in the expanded position, the backing sheet can be spaced the same length of the fin 107 by a predetermined distance. The panel 106 can be attached to the support tube 116 by an adhesive positioned between the top edge of the panel and a line extending longitudinally along the length of the support tube. Another means of attachment can also be used, such as double-sided tape, rivets, or even an upper sheath positioned within a receiving groove. Panel 106 can be connected to support tube 116 by a separate piece of material, plastic, or even laterally spaced strings or discrete connections.
    [0032] With reference to Figs. 2, 6A, and 6B, pseudocells 108 can be defined at least in part by the backing sheet 110, the flap material 112 and the backing member 114. The flap material 112 and the backing sheet 110 can be substantially of any material and can be the same or different from each other. For example, in some embodiments, the fin material 112 and the backing sheet 110 may be a woven, non-woven, woven or knitted material. In addition, fin material 112 and backing sheet 110 consist of separate pieces of material sewn together or otherwise attached to each other in horizontal or vertical stripes, or in other shapes.
    [0033] Additionally, fin material 112 and backing sheet 110 may have varying light transmissivity properties. For example, fin material 112 and / or backing sheet 100 may be made of thin fabric (allowing a substantial amount of light to pass through it), luminescent fabric (allowing some amount of light to pass through it), or a black-out fabric (allowing little or no light to pass through). Both fin material 112 and backing sheet 110 can also have insulating properties along with aesthetic properties. In addition, fin material 112 and backing sheet 110 may include more than one individual sheet or layer, and may be made of a different number of sheets or layers operatively connected to one another. The fin material 112 can have a high level of draping (less rigid), or a low level of draping (more rigid), which can be selected to obtain the appropriate shape or fin 107. A finer fin material 112 it may not result in an “S” shape as pronounced as that shown in Figs. 6A. As explained in more detail below, a less rigid fin material can result in a more pronounced "S" shape than shown in Figs. 6A.
    [0034] In some configurations, as shown in Fig. 2 and 6A, fins 107, in combination with backing sheet 110 and adjacent fins 107, can define pseudocells 108. For example, a first fin 107 may have an edge bottom that can, in the extended position, touch an upper surface of a second lower adjacent fin 107. Thus, pseudocells 108 can be defined by the backing sheet 110, the fin material 112 of a first fin 107a and an adjacent second fin 107b a and just below the first fin 107A. The rear surface of the upper edge of the first fin material 112 of the first fin 107a is fixed along its length, continuously or intermittently, to a front surface of the backing sheet 110 by a fin connection mechanism 122. Each pseudocell 108 has , as directed when positioned over a window in a building, a front side (for example, a side facing the interior) which is defined as the portion between the upper joint (fin connection mechanism 122) of fin material 112 with the backing sheet 110 and a lower edge 125 of the fin 107. Each pseudocell 108 has a rear side (for example, facing the window), defined as the portion of the strut leaf 110 extending between its junction (connecting line 122) with the fin fabric at the top and continuing down to the bottom edge 125 again.
    [0035] With specific reference to Fig. 2, fins 107 may have a dimension Hc that extends from the upper edge of the first fin material 112 to a lower edge 125. The dimension Hc represents the total linear height of fin 107 along the length of the backing sheet 110 (vertical in its orientation, but it can have a horizontal width where the invention is applied laterally to an architectural opening). In addition, an adjacent lower fin may extend beyond the lower edge of an upper fin 107 in an overlapping dimension Ho. The Ho dimension can be the distance between the lower edge 125 and the upper edge of the lower fin 107. The Ho dimension represents the linear height along the backing sheet 110. It is contemplated that both Hc and Ho can also be measured along the curvilinear surface of the fin.
    [0036] The value of Ho, either as a percentage of Hc or as an absolute value, affects the external appearance of the blind, among other things. Where Ho is relatively large (ratio or dimension), it will result in less than the height (with reference to Fig. 2) of the front fin material 112 of the fin 107 being shown. Where Ho is relatively low (ratio or dimension), it will result in more than the height of the front fin material 112 of the fin 107 being shown. The Ho dimension can be designed to be consistent with a length of a blind or it can vary, depending on the desired aesthetic effect.
    [0037] Additionally, the value of the Ho dimension can affect the distance that the fin material 112 extends away from the support material 110, which would affect the volume of pseudocell 108 and the distance that fin 107 can extend far away. of the backing sheet 110, and thus can affect the insulating properties of pseudocells 108. Other characteristics of the louver structure can also work together with the Ho value to affect the distance that fin 107 can extend away from the sheet support 110. In addition, the Ho value affects how many layers the light must pass through as it reaches the back of the support sheet 110. At Ho's reach, the light passes through three layers, for example, with respect to Fig. 2. Out of Ho's reach, light passes through two layers. This can affect the appearance of any “streak of light” or shadow on the blind.
    [0038] As best shown in Figs. 6A and 6B, the front surface of the first fin material 112 can be positioned, but disconnected from, a front surface of the fin material 112 of the second fin 107b. The position of the first fin 107 in relation to the second fin 107b can form pseudocells 108 since the upper fin material 112 may appear in an extended position to be attached to the second fin 107b, thus forming a "cell". In one example, a lower edge 125 of the first fin 107a may rest on a top surface of the fin material 112 of the second fin 107b. However, because the upper fin 107a may not be directly connected to the lower fin 107b, the two fins 107 can move relative to the other fins 107. For example, the first fin 107a may extend away from the backing sheet 110 without substantially causing the second fin 107b to also extend away from the backing sheet 110.
    [0039] The fin material 112 of the second fin 107b is fixed by the fin connection mechanism 122 generally along an upper edge to the front side of the backing sheet 110. The upper edge of the fin material 112 of the second fin 107b it is positioned on the support sheet 110 at about the midpoint of the height H1 of the first fin 107a. This position can be higher or lower depending on the desired fin shape. The shape of pseudocells 108 is thus formed by combining the fin material 112 of the first fin 107a, the backing sheet 110, and the upper portion of the fin material 112 of the second fin 107b. The cross section of chamber 105 is approximately teardrop-shaped with a narrow upper portion and a more bulbous lower portion. In other embodiments, the shape of the chamber 105 can be configured differently and / or reduced.
    [0040] Figs. 4 and 5 show the fin material 112, the support member 114, and the support sheet 110 prior to forming. Fig. 4 is an exploded view of the backing sheet and fin 107. Fig. 5 shows a fin connection mechanism 122 positioned over the upper portion of the fin material 112. The fin connection mechanism 122 is positioned at a distance from the upper edge of the fin material 112 to form a support 124 (see Fig. 6A) or free edge of the fin material 112 above the location where the fin material 112 is attached to the backing sheet 110.
    [0041] With reference to Figs. 6A and 6B, the flap connection mechanism 122 may have a height of H3 instead of a single connection line having little width (a relatively thin line). Where the connection mechanism 122 has a height H3, it provides a bonding force between the fin material 112 and the backing sheet 110 on its height H3, such a bonding force that helps to keep the fin material 112 in closer proximity. close to the backing sheet 110 even under the bending load that propels the fin material 112 away from the backing sheet 110 caused by the fin material 112 of the adjacent upper fin. In such cases, the flap connection mechanism 122 can facilitate the refinancing of the flap 107 in a more "closed" configuration when the blind is extended. That is, the lower edge 125 of the fin 107 may be prone towards the upper surface of the fin material 112 of the adjacent lower fin 107. This is because the height H3 can help prevent the fin material 112 from extending away. of the backing sheet 110, which could allow adjacent fins 107 to extend away from each other, and thus “opening the pseudocells” and potentially releasing air, reducing the isolation characteristics of pseudocells 108, also creating a less complex appearance. panel uniform.
    [0042] Referring again to Fig. 6A, as discussed above, the fin material 112b of the second fin 107b extends upwardly on the backing sheet 110 to a height that can overlap with the height of the first fin 107a.
    [0043] Additionally, the fin material 112 can form a general "S" shape. In some cases, the transition point between the curve is concave towards the anchor sheet 110 (where the support member 114 is positioned on the fin), and concave away from the support sheet 110 (above the support member 114 ) is defined by where the fin 112 is attached to the upper end of the support member 114.
    [0044] With reference to Figs. 2, 3, and 6A, the support member 114 can support the fin material 112 and help form the shape of the fins 107. The support member 114 can have a partial or substantially rigid material that can retain a particular shape. Support member 114 is resilient in that it can be bent or flexed from its normal shape and returned to its formed shape. For example, support member 114 can be of any thermoformable material that can be heated to form a particular desired shape. In addition, support member 114 can be reshaped, allowing the general format of support member 114 to be changed repeatedly. The formation of support member 114 is discussed in more detail below.
    [0045] Support member 114 may extend along at least a portion of the fin material 112 between the locations of the fin connection mechanisms 122 and the lower edge 125 of fin 107. In some instances, the fin material 112 can be sufficiently rigid (having structural properties) so that the "S" shape is formed regardless of the weight of the supporting member 114 and the fin under it. In this way, the stiffness of the support member 114 creates a twist or torque at its upper junction with the fin material 112, and the stiffness of the fin material 112 as it extends upwards from that point is leveraging the entire assembly of fin 107 outwardly (laterally away from the anchor sheet 110), creating a chamber 105 or deeper distance from the backing sheet 10 than if fin 107 had been defined by the curve of the supporting member 114 itself. The supporting member 114 and fin material 112 can be operatively connected to each other in the support connection mechanism 120. The support connection mechanism 120 can be adhesive, fasteners, stitching, and the like. In other embodiments, the support member 114 can be molded on or impregnated in the fin material 112, as discussed in more detail below.
    [0046] In some embodiments, the support member 114 may be plastic, moldable laminate, fibers, moldable tape, adhesive, polyvinyl chloride, polypropylene, or the like. For example, support member 114 may be of a thermoformable material, such as a laminated material, and may have an adhesive-like property when heated and then cooled. In other examples, support member 114 may be of a partially thermoformable material that may have an increased adhesive-like property when heated and / or cooled, but may not completely break free of its original shape or structure during heating and / or cooling . In addition, the fin material 112 can also be impregnated with the supporting member 114.
    [0047] Additionally, the support member 114 can be configured to have aesthetic properties. Similar to fin material 112 and backing sheet 110, the backing member 114 may have varying light transmissivity properties, for example, the backing member 114 may be thin, transparent, opaque or black-out. In other embodiments, the support member 114 may be a wooden blade. A wooden blade fin material can be positioned outside the fin material with the backing material under it to create the shape. If the blade was used without additional backing material, it can be formed to be curved in shape when wetted, then rolled over a roller or forming tube, and dried in the oven heat to establish the curvature of the blade. This blade formation may or may not be repeatable to reform the wooden blade with a different curvature. In addition, support member 114 can be of varying thickness and, in some embodiments, support member 114 can be as thin as or thinner than fin material 112. In some embodiments, the support member can typically be PET (polyester film) approximately 0.002 inches thick. If made from another material (such as PVC), the thickness can be greater or less, with a thickness range from about 0.001 inch to about 0.010 inches. In these embodiments, the fin 107 may remain substantially flexible and may be able to flex, bend, and / or wrap around the support tube, although the support member 114 may be of substantial / partially rigid material.
    [0048] The support member 114, as shown in Fig. 6A, is positioned on the inner surface of the fin material 112 of the first fin 107a, facing the support sheet 110. In other cases, the support member 114 can be positioned on an external surface of the fin material 112. In some embodiments, the support member 114 can be integrally formed with the fin material 112 or can be applied on the external surface of the fin 107. With reference to Fig. 3, the support member 114 is shown as a separate part that is positioned on the fin material 112 towards the support sheet 110. It should be noted that the support member 114 can be positioned on the front surface of the fin material 112, or it can be integrally formed with fin material 112 (such as fin material 112 being impregnated with a thermoformable material to allow it to become resiliently formed).
    [0049] The support member 114 can extend laterally along the total length of the fin 107 (from one side to the other of the width of the panel 106). The support member 114 can also extend over a portion of the length of the fin 107, or it can include a plurality of cell support members 114 positioned in discrete positions along the length of the fin 107.
    [0050] The support member 114 can be adhered to the fin material 112 continuously along its entire length, continuously along a portion of its length, in positions spaced along its length, on the upper and lower edges of the member support 114, or elsewhere. The variation in height as well as the placement of the support member 114 in the fin 107 can alter the shape of the fin 107 and the chamber 105, as well as the distance or space between the support sheet 114 and the fin material 112 when the fin 107 are extended away from the backing sheet or “open”. For example, a smaller support member 114 can create a shorter distance between support sheet 114 and fin material 112, which can make the sheet appear "flatter" compared to a fin 107 that has a member 114 greater support.
    [0051] Since the panel 106 is unwound from the support tube 116, and the fins 107 are in their extended position, the curvature of the support material 114 effectively shortens not the length of the front side of the fin 107, but the distance in straight line between the lower edge 125 and the upper junction (connection line 122).
    [0052] One aspect of the slat structure disclosed here is the constant appearance during retraction and extension of the blind panel from the support tube. In many cases, blinds are retracted by stacking from the bottom up, which changes the appearance of the blind at the bottom of the blind panel as it is compressed and collected by raising the lower rail. The same distortion of the shutter occurs during extension of the stacked shutter. In at least one example of the blind as described and disclosed here, the appearance of the battens or pseudocells (individually or collectively) during retraction and extension is not substantially affected and, in some cases, is not affected at all.
    [0053] The blind panel, for example, 106 in Fig. 1, and also partially shown in Fig. 2, for example, includes a slat panel extending laterally and positioned one above the other vertically. Each cell has a height and amount of fin curvature defined, at least in part, by the curvature created by the cellular support material, as well as by the locations of attachment of the fin material to the support sheet. This height and curvature creates a first appearance for the individual slats. Note that the individual battens may each have a different first appearance, or may have a similar or identical first appearance. The plurality of strips that form the blind panel also creates a total or collective appearance, which can be created by two adjacent or non-adjacent strips, or more than two adjacent strips. The appearance of this slat collection creates a second appearance.
    [0054] Unlike the changing appearance of stacked cellular blind panels when retracted or extended, the appearance of at least one example of slats disclosed and described here does not change substantially by extension or retraction. In other words, the appearance of individual slats or a collection of slats is not greatly affected by the amount that the blind is extended, or by the act of extending or retracting the slats. This constancy of appearance, both individually and collectively, is due to the use of the support tube to retract and extend the slats. Since the support tube is engaged or operatively associated with the upper portion of the louver panel (such as attaching to the backing sheet), the appearance of individual slats and / or the collection of slats is not substantially changed between the bottom ( or under) the support tube and the bottom rail positioned at the bottom edge of the blind panel. Until the actual engagement around the support tube (during retraction), the appearance of a particular lath is largely unchanged from its appearance when the blind is fully extended. The collective appearance of the slats between the main tube and the bottom rail (unlike the blind panel becomes shorter in length) is also largely unchanged. Similarly, by extension from a retracted position, once a lath has been unrolled from the support tube, its individual appearance is largely unchanged during extension below the main tube.
    [0055] Unlike stackable cellular blinds, in at least one example of the lath structure described and disclosed here, the appearance of the individual lath or collection of laths under or not engaging the support tube is largely unchanged during retraction and extension. The height, curvature or lateral depth (from the front of the fin material to the backing sheet, as created by the chamber size), which together or individually create or affect the appearance of the individual battens or the batten collection, are substantially unchanged . The effect is that the blind panel has a clean and consistent appearance that is not greatly affected by the vertical position (amount of retraction or extension) of the blind panel. Forming the Panel
    [0056] Referring now to Figs. 3, 4 and 5, panel 106 can be formed in a variety of different ways. However, in some embodiments, the support member 114 is formed so that it can be shaped to approximate an arc of curvature or external perimeter shape for the support tube 116 as modified by any underlying layers of the cellular blind already rolled up. around the support tube 116. For example, as shown in Fig. 4, previously to be formed (as will be discussed in more detail below), the support member 114 can be substantially flat (for example, linear). However, as shown in Fig. 3, after formation, discussed in more detail below, the support member 114 may have an arcuate shape or curvature. This curvature or arcuate shape may be substantially the same as a portion of the perimeter of the support tube 116 or another forming mandrel or tube. In these embodiments, as the fins 107 are wound around the support tube 116, the support member 114 can be wrapped around the support tube 116, although it may be substantially or partially rigid or resilient. Because the support members 104 are resiliently flexible, they can adapt to several different shapes when rolled, such as a greater or lesser radius of curvature. Because the support member 114 can substantially approach the same radius of curvature as the support tube 116 (due to the forming process, discussed below), each support member 114 can wrap around a portion of the support tube 116 (as well as any fins 107 already wrapped around the support tube 116). Specifically, as the diameter of the support tube 116 and the rolled blind increases, the radius of curvature for the support member 114 changes, so that the radius of curvature for fins 107 near the top of the blind has a smaller radius than those at the bottom.
    [0057] Support members 114 can be formed (or reformed) around support tube 116 to create the desired formed shape. In some embodiments, before the support member 114 is formed, it can be substantially flat and thus the fins 107 can rest directly against the support sheet 110. Due to the at least partial resilience of the support member 114, the members support strips 114 may not break or crack as they are wound around support tube 116 prior to forming.
    [0058] To form the panel, the fins 107 can be operatively connected to the support sheet 110 prior to the support members 114 being formed and / or wound around the support tube 116. For example, the connecting member 122, the which can be adhesive, can be applied over any of the fin materials 112 on the backing sheet 110. Panel 106 can be formed by aligning the supporting members 114 with the finials 112, applying the supporting connection mechanism 120 to the member support material 114 and fin material 112. Then, the fin material 112 can be connected to the backing sheet 110 by the fin connection mechanism 112. For example, in cases where the fin connection mechanism 122 is an adhesive, the adhesive lines can be applied to the backing sheet 110. Once the connection mechanism 120, 122 is applied to one of the fin material 112, backing member 114, and / or backing sheet 110, panel 106 or portions of it can be heated or otherwise (for example example, by means of a joining or melting bar) at a first temperature (or otherwise activated) to adhere fin material 112 and backing sheet 110 together.
    [0059] As a specific example, a melt bar or a tie bar can apply pressure and / or heat to activate connection mechanisms 120, 122 (which, in some cases, can be activated by pressure or activated by heat ). In some cases, connection mechanisms 120, 122 may have a high activation or melting temperature, for example, approximately 410 degrees Fahrenheit (210 ° C). This first temperature can be higher than a second temperature used to form the support members 114, discussed below.
    [0060] Once the fin material 112 and the support sheet 110 are connected to each other, the panel 106 can be wrapped around the support tube 116. After the panel is wrapped around the support tube 116, the support tube 116 and the panel 106 can be heated to a second temperature, which can be lower than the first temperature. For example, during this operation, panel 106 can be heated in this process to a temperature of approximately 170 to 250 degrees Fahrenheit (76.7 ° C to 121.1 ° C), for up to approximately one and one and a half hours. A temperature of 175 to 210 degrees Fahrenheit (79.4 ° C to 98.9 ° C) for approximately 15 minutes has been found to be adequate in some circumstances. Other temperatures and times may also be acceptable.
    [0061] As the panel 106 is heated, the support members 114 can become formable and adapt to the support tube 116. As the material of the support member 114 is heated, it can adapt to the shape of the support tube 116 , as well as connect operatively to fin material 112 (if not yet connected to each other). Additionally, in some embodiments, the support member 114 can adapt to the shape of the support tube 116 plus any layers of panel 106 around which it may be wrapped. For example, cell support members 114 for cells 108 in an outermost layer of panel 106 may have a greater curvature diameter than cell support members 114 for fins 107 in an innermost layer.
    [0062] In some cases, the connection mechanisms 120, 122 can be activated at a higher temperature than the formation temperature of the support member 114. In such cases, the support members 114 can be formed without substantially affecting the connection of the fins 107 to the backing sheet. Thus, support members 114 can be formed after panel 106 has been substantially assembled and / or connected. For example, the connection mechanism 120, 122 can be high temperature pressure-grip adhesive, which can allow the support member 114 to be formed by heated processes, without substantially weakening or destroying a connection between the fin material and the backing sheet. For example, fin connection mechanisms 120, 122 may have a higher melting point than a material used to form supporting member 114. In one case, the melting point for fin connection mechanism 122 may be in the range between 350 and 450 degrees Fahrenheit (176.7 ° C to 232.2 ° C) and, in a specific case, it can be 410 degrees Fahrenheit (210 ° C). This allows the support member 114 to be formed and possibly reformed at the required temperature without affecting the adhesion properties of the fin connection element.
    [0063] After heating panel 106, support tube 116 can be cooled. During cooling, the support members 114 can stiffen or stiffen in the shape of the support tube 116. This is because the support members 114 can become at least partially formable or moldable when heated, but after the heating process the Supporting members can harden back into a substantially resilient shape.
    [0064] Once cooled, the support member 114 can maintain the general shape of the support tube 116 and thus be slightly curved. Thus, after forming the support member 114, the fins 107 can be curved as shown in Fig. 6A. This allows support member 114 to be wrapped around support tube 116 when in a stored or retracted position because the shape of support member 114 generally adapts to support tube 116. Support members 114 then, as described below, they help propel their respective fins 107 away from the backing sheet 110 to an open position when unwound from the backing tube 116.
    [0065] For example, in some embodiments, the support member 114 can be generally shaped as a portion of a "C", so as panel 106 wraps around a cylindrical support tube, the support member support 114 can adapt to a portion of the perimeter of support tube 116. This makes it easier for fins 107 to be wrapped or rolled around support tube 116 in the stowed position, and also extend away from support sheet 110 for “ open ”as panel 106 is unwound from the support tube 116. The resistance of the support member 114 and its connection to the support sheet help with the automatic opening characteristics.
    [0066] Panel 106, although originally formed around a support tube 116, can be disconnected from the original support tube and re-attached to a different support tube (such as having a support tube of larger or smaller diameter) to subsequent reform. The top edge of panel 106 can be attached to a new support tube 116 or by a sheath received in a groove, or other means. In addition, if a portion of a panel 106 is separated from a greater length of panel 106 by a side slice along the width of panel 106, the now separated panel 106 may be attached to a new support tube (such as by means described here) having the same diameter as the original support tube, or it can be attached to a new support tube having a different diameter from the original support tube and be reformed.
    [0067] After the support members 114 are formed and the panel 106 is operatively connected to the support tube 116, a section of panel of different widths can be formed by cutting the combination of the involved panel 106 and the support tube 116 to the desired length . In these embodiments, end caps or the like can be placed on the end ends of the support tube 116, creating a refined appearance. For example, a single support tube 116 can be used to create multiple different panels or blinds for a variety of architectural openings. Operating the Dashboard
    [0068] Operation of panel 106 will now be discussed in more detail. As discussed above, panel 106 can be wrapped around support tube 116 or another member (e.g., rod, roller, mandrel, etc.). See, for example, Fig. 9, among others. As the fins 107 are wound around the support tube 116, the fins 107 and the support sheet 110 can close on the fins 107 so that each fin 107 can substantially adapt to a perimeter of the support tube 116. This is possible since backing sheet 110 can wrap tightly around backing tube 116, and as it does, backing sheet 110 closes on the fins, which then wrap around backing tube 116. As the support tube 116 curls (or rolls), the support members 114 can then be forced to adapt to the effective perimeter of the support tube 116 and underlying layers of the blind. Thus, the support members 114 can be closed to rest adjacent to the support sheet, substantially closing the chamber 105 formed between the fins 107 and the support sheet 107 when the panel 106 is in the extended position.
    [0069] Continuing with reference to Fig. 6A, as the panel 106 is unwound from the support tube 116, for example, extended, the fins 107 extend away from the support sheet 110 to create the chamber 105 and pseudocells 108. According to the support tube 116 is rotated to extend the panel, the support sheet 110 also unwinds. As support sheet 110 unwinds, support members 114 also unwind around the perimeter of support tube 116. Over support tube 116, the shutter material is closed in closely spaced layers (and the members of support 114 generally maintain an equal or similar amount of curvature when in the extended position). As the blind or panel 106 is extended as the support tube 116 consequently rotates, the strut or support sheet 110 is suspended substantially vertically downwards. The fin material 112, under the force of the support member 114, converts to the open configuration and extends away from the support sheet 110 to define the chamber 105 and pseudocells 108. This expanded or open shape is caused by the support material 114, in combination with the structural effect on the fin material 112 of the upper connection points, as described in more detail below. As any of the support members 114 are deformed when rolled upward on the support tube 116, the resilience of each of the support members 114, by unrolling, propels the fin material 112 into its formed shape, for example , similar to a "C", to create chamber 105. Support member 114 and fin material 112 thus extend away from support sheet 110 to form pseudocell 108 and inner chamber 105.
    [0070] In some embodiments, a portion of the fin material 112b for the second fin 107b may extend upwards behind the first fin 107a and connect to the front surface of the backing sheet 110. That upper edge of the fin material 112b for the second fin 107b it can be connected to the front side of the backing sheet 110 by the fin connecting member or rear connection mechanism 122. The rear connection mechanism 122 can be approximately at a midpoint of the first fin 107a. The fin material 112 can connect to the backing sheet 110 so that there can be a support 124 or free edge that can extend above the fin connection mechanism 122.
    [0071] With reference to Figs. 6A and 6B, although support 124 can (but is not required to) assist fins 107 to expand to an “open” position (that is, transitioning from a closed position to an expanded position), the support provides tolerance dimensional to apply a connection mechanism 122 (such as a glue or adhesive line) along the edge. In some cases, panel 106 can also be retracted in a stacked configuration, rather than wrapped around support tube 116. See, for example, 11. In this configuration, each fin 107 or batten can be positioned in a relatively straight alignment. straight vertically underneath each other. For example, terminal rail 104 (or terminal fin) can be moved vertically upwards towards main rail 102 or support tube 116. This can be accomplished by one or more support ropes extending from main rail 102 ( or other suitable structure at or near the top of the blind) across the length of panel 106 and connecting to end rail 104. The support strings are then acted to pull end rail 104 up toward main rail 102, stacking thus, the fins 107 as shown. Many known mechanisms are suitable for dragging the support strings to the main rail 102. And so, instead of wrapping around the support tube 116, the panel 106 can be stacked vertically in a line. Thus, each fin 107 or slat may close vertically over each adjacent fin 107. Alternative Examples of the Panel
    [0072] Fig. 7 illustrates another modality for a panel cover for an architectural opening. In this embodiment, the fins or battens including a lath support 214 and / or fin material 212 can be operatively connected to a backing sheet 210 to form an architectural cover that can be used to prevent light from entering directly into a window or the like . In this embodiment, instead of having pseudocells 108 or having the fins 107 oriented downwards towards the terminal rail 104, the panel 202 may include strips 211. The strips 211 may be substantially similar to the strips 107, but they may be curved or generally shaped as a portion of a “C” shape, so that the strips 211 can curve upwards towards the support tube 116. For example, an average portion of each strip 211 may be lower in panel 202 ( with respect to the support tube 116) than an upper part of each batten 211. In these embodiments, the battens 211 can be shaped so that they can be rolled around the support tube 116 when the panel is in a retracted position. For example, as shown in Fig. 7, the strips 211 can have substantially the same curvature as the support tube 116, so that the panel is wrapped around the support tube 116 the strips 211 can be positioned around the tube support 116.
    [0073] The battens 211 may include a batten support layer 214 and a fin material 112. Fin material 112 may cover the entire batten support layer 214 or only a portion of the batten support 214. In others embodiments, the battens 211 may include only the batten support layer 214. The battens 211 may each be operatively connected to the batter sheet 210, for example, by means of adhesive, fasteners, stitching, and so on.
    [0074] Slat support 214 can be substantially the same as support member 114. For example, slat support 214 can be of a thermoformable material that can be resiliently flexible after being formed. These modalities allow the slat support 214 to support and maintain the shape of the slats 211. For example, as shown in Fig. 7, the slats 211 can be curved upwards towards the support tube 116 and (like the cell support 214), the battens 211 may be partially resilient, so that each batten 211 may remain in a particular shape.
    [0075] Fig. 8 illustrates another modality of a panel for an architectural opening. In this embodiment, a series of slats 311 or fins can be curved downward or away from the support tube 116. In this embodiment, the slats 311 can be oriented similar to the fins 107 illustrated in Fig. 1, but they may have more of the shape of "C" than the "S" shape. In this embodiment, the strips 311 can also form pseudocells since each lath 211 can rest against (or above) each previous lath 311; however, the slats 311 may not be directly connected to each other. For example, each lath 311 can be operatively connected to the backing sheet 110 (for example, by means of adhesive, stitching, etc.) along an upper edge thereof, but may not be fixedly connected to the adjacent lath 311. These modalities allow the slats 311 to open in a rotating or flexible way. Additionally, as shown in Fig. 8, the backing sheet 310 can include steps 317 at the connection location of each batten 311. The steps 317 can be formed as a connection mechanism 122 for connecting the battens 311 to the backing sheet 310 can extends along an interface to pull the backing sheet 310 out a distance along the connection to the slats 311. Thus, the backing sheet 310 can be scaled down, because the slats 311 can pull a portion of the backing sheet support 310 forward at the connection site.
    [0076] Figs. 9 and 10 illustrate another modality of a panel 302 for an architectural opening. In this example, a single backing sheet 310 can support two sets of strips 211, 311 and / or fins 107. For example, a back side of backing sheet 310 may include strips 211 that extend outwardly and curve upwards in towards the support tube 116 and a front side of the support sheet 310 can include slats 311. As illustrated in Fig. 9, the slats 211 or fins on the back of the support sheet 310 can be curved downwards and operatively connected to a front side of the backing sheet 310. In these modalities, if the architectural opening is a window, the strips 211 can prevent direct rays of light from passing through the backing sheet 310. The strips 211, 311 can provide insulation as well as be aesthetically pleasing . For example, slats 311 can be formatted as quasi-cells or pseudocells, see, for example, Fig. 8. Thus, panel 302 can be an architectural cover with two functions in which it can prevent direct rays of light from passing through of the backing sheet 310, since the strips 211 can substantially block direct rays of light, and it can provide insulation by means of the strips 311, which can be configured to form quasi-cells. In addition, the battens 211, 311 of Figs. 8 or 9 can be operatively connected to panel 106 of Fig. 6A. In this embodiment, the strips 211, 311 can be connected to an opposite side of the backing sheet 110 from the fins 107.
    [0077] As described above, each of the slats 311 can open since each slat 311 may not be fixedly attached to adjacent slats 311. This allows the panel to be placed in a stacked position when retracted. For example, Fig. 11 illustrates the panel of Fig. 10 in a stowed position. To stack the panel, the terminal rail 104 can be pulled vertically upwards towards the support tube 116, (for example, by means of retraction lines or ropes), and instead of rolling the panel around the support tube 116. In this way, the panel can be stacked so that each lath 211, 311 can be positioned one under the other. As panel 302 is retracted, slats 211, 311 extend upward and outward and can be positioned directly adjacent to each other.
    [0078] Furthermore, as best shown in Fig. 10, in some examples, the battens 211 formed on a back surface of the backing sheet 310 may include only a slat support structure 214, and the fin material 112 may be omitted . In these embodiments, the lath support structure 214 can include a pattern, color or the like (in other words, it can be aesthetically pleasing). The slats 311 formed on the front side of the backing sheet 310 may include a slat support 214 that can be partially covered or completely covered by the fin material 112. For example, the fin material 112 can wrap around the fin support 214 or it can end at one end of the flip support 214.
    [0079] Fig. 12 illustrates another example of a 506 panel to cover an architectural opening. The panel 506 may include strips 511 or fins that can be operatively connected to the backing sheet 110 by a connecting member 515, effectively causing the strips 511 to be made of a two-piece construction. In this embodiment, an effective length (as measured along the vertical length of the panel from the vertical rail to the floor) of the slats 511 with respect to the backing sheet 110 can be extended, because the connecting member 515 extends an appearance of the length of each batten 511. The connecting member 515 can also extend the battens 511 away from the backing sheet 110, so that the panel 506 can have a greater total width (as measured between the strut sheet and the battens) than in other modalities. The connecting member 515 can be operatively connected to the backing sheet 110 by means of an adhesive 522 or other fastening means, and to the batten 511 by means of an adhesive or other fastening means. Connecting member 515 may be similar to fin material 112 or may otherwise be of a generally flexible material that is configured to be wrapped around support tube 116.
    [0080] Each slat 511 can be operatively connected to backing sheet 110, but may not be operatively connected to other strips 511. As such, similar to fins 107, strips 511 can form quasi-cells, where when panel 506 is in an extended position, the strips 511 can create a pocket or chamber, but when retracted, the strips 511 can extend away from the other strips 511. The strips 511 can be positioned so that they can bend or arch towards backing sheet 110; however, the arc of curvature can be minimized compared to the strips 511 illustrated in Figs. 7 and 8. For example, the strips 511 shown in Fig. 12 can be slightly rounded, instead of having a more pronounced curve like the letter "C". Connecting member 515 can be curved having a concave side generally facing away from the anchor sheet 110, with the batten 511 being curved and having a concave side generally facing towards the anchor sheet 110. The batten 511 and / or the connection member 515 can have more than one curve along their respective lengths.
    [0081] The slats 511 are operatively connected by means of an adhesive strip 518, the adhesive strip 518 can be positioned on an upper outer surface of the connecting member 515 and a lower surface of an upper portion of each slat 511. Since the slats 511 are curved towards the backing sheet 110, the adhesive strip 518 can be partially accommodated since the adhesive strip 518 can be positioned between the upper surface of the connecting member 515 and a lower surface of the strip 511.
    [0082] It is contemplated that the blind can be retracted or extended by control ropes or by a motor-drive system. When using control ropes, the control rope (s) would allow manual retraction or extension by a user to the desired position. The control string (s) engages (ar) and arches (m) a drive mechanism operatively associated with the support tube, and positioned on or adjacent to the terminal rail. The drive mechanism can include a clutch (spiral spring or other) and transmission (such as a planetary gear mechanism) to improve the gear ratio and allow retraction and extension with less load on the control string.
    [0083] In the motor drive system, a motor overturns the support tube to retract the louver panel by wrapping it around the support tube during retraction, and turns the support tube to unwind the louver panel from the support during extension. The motor drive system may include a drive mechanism, such as an electric motor (which may or may not be reversible), which is operatively associated with the support tube. The motor can be integrated into the support tube, or it can be separated from the support tube (in axial alignment or not). The motor is shown attached to a shaft mounted on the support tube by a belt drive, but it is contemplated that a gear drive mechanism, planetary gear mechanism, or the like can also be used. The motor is powered with electricity from a battery source, voltage per line, or others, and its operation to retract or extend the blind panel is controlled by the user via a manual switch (wired or wireless), or automated via a motor controller. The motor controller can be in communication with and controlled by a programmable logic controller, which can include a processor to allow direct control by a user, as well as software-based control instructions responsive to time control signal (s) actual from associated sensor (s), or pre-programmed signals from a control program. In addition, the controller can be in communication with the internet or a dedicated local communication system to allow remote control by a user, manually or automatically. The control signals provided to the motor manually or via the motor controller can be wired or wireless (for example, RF, IR, or others as it is known). The motor controller can be in wired communication with the motor, and the logic controller can be in wired communication with the logic controller, each being discrete elements of the system. It is contemplated that the motor controller and the logic controller can be integrated into the motor (an “intelligent” motor), which would allow fewer components and a smaller total system. The retraction of the motor-controlled blind panel would thus control the retraction and extension of the cellular blind panel as defined here by being rolled and unrolled around a support tube. This action can be implemented without the use of any manual control strings and the associated maintenance, potential breakage and other problems associated with the use of control strings.
