BACKGROUND
Fenestration generally refers to products that fill openings in a building envelope, such as windows, doors, skylights, curtain walls, etc. These products are designed to permit the passage of air, light, vehicles, or people. A building envelope, in turn, generally refers to the separation between the interior and the exterior environments of a building. As such, the building envelope serves as an outer shell that both protects and facilitates climate control of the indoor environment.
During daylight hours, light may be blocked at a window to reduce or eliminate the glare caused by the sun light passing through a window. This blocks a substantial portion of the view from the window, and thereby removes many benefits provided by a window. There have been efforts to modify a window by directly applying thereon a glare-reducing film that is sufficiently transparent so as not to obscure the view through the window.
Unfortunately, directly applying a film to the interior surface of a window, as conventional designs propose, suffers from drawbacks. Specifically, the amount of light and heat that is reflected does not rise to the desired levels to be considered energy efficient. In fact, the conventional window/film combinations absorb a greater amount of light and/or heat than desired through impingement upon the combination and heat remaining contained inside the building envelope.
Further, windows and other fenestration products may include only a single pane of glass and/or may not otherwise perform at an acceptable thermal or radiant energy efficiency. A conventional approach to improving the performance of low-efficiency fenestration products includes simply replacing the window or other fenestration product with a more energy efficient product. However, such a measure may be expensive, inconvenient, or not possible, especially in the case of historical homes, high-rise buildings, apartments or other rental properties, or buildings having a large number of windows.
Therefore, there exists a need for a fenestration assembly that is cost-effective, is easily installable into various types of buildings, and provides a high level of energy efficiency.

DETAILED DESCRIPTION
For the purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of this disclosure is thereby intended.
Referring now to the drawings, FIG. 1 A illustrates a fenestration assembly 10 for installation into a building opening 12, such as a window or door opening in two non-limiting examples. In an embodiment, the fenestration assembly 10 is installed against or adjacent to a window pane 62, as illustrated in FIG. 2. The fenestration assembly 10 of an embodiment includes a first side 14, a second side 16, a third side 18, and a fourth side 20.
In one or more embodiments, the assembly 10 includes one or more brackets 36, as illustrated in FIG. 1A. In additional embodiments, the assembly 10 does not include the brackets 36. As discussed in further detail below, the bracket 36 couples, fixes, or attaches the assembly 10 to the building opening 12, such as a window frame in one non-limiting example. The bracket 36 of an embodiment may be positioned at a central location 38 of one or more of the sides 14, 16, 18, 20 to provide tension separate from, in addition to, or as a supplement to a primary biasing force 32 and against a film tensile force 34, explained in further detail below, and/or straighten the one or more sides 14, 16, 18, 20 upon installation of the assembly 10 into the opening 12.
Referring now to the embodiment of FIGS. 1B and 2 with continuing reference to FIG. 1A, each of the sides 14, 16, 18, 20 includes a base 22, a slide 24, and a primary biasing member 26. FIG. 1B shows an enlarged plan view of the base 22, the slide 24, and the primary biasing member 26 positioned under the slide 24 of the side 20 of the assembly 10. The components shown in FIG. 1B may be included in each of the slides 14, 16, 18, 20. Some components of the assembly 10, such as a cap 40 and a film 30, described in further detail below, are not shown in FIG. 1B for clarity purposes. In an embodiment, the base 22 is configured to be coupled to the building opening 12, such as a window portion in a non-limiting example. The window portion described herein refers to a window frame, a window pane, a window sill, and/or any other portion of a window. As illustrated in FIG. 1A, a corner key 72 joins two of the sides 14, 16, 18, 20. The corner key 72 is positioned in a keyway 74, as illustrated in FIG. 2. The corner key 72 is positioned at all corners of the assembly 10 in an embodiment to reinforce and/or add rigidity to the assembly 10. Further illustrated in FIG. 1A, an optional straight key 76 may be positioned in the keyway 74 of one or more of the sides 14, 16, 18, 20 in order to reinforce and/or add rigidity to the assembly 10 and/or resist or compensate for inward bowing or cambering of one or more of the sides 14, 16, 18, 20.
The slide 24 is positioned adjacent to the base 22, as illustrated in FIG. 2. The primary biasing member 26 is positioned between the slide 24 and the base 22 to apply the primary biasing force 32 against each of the slide 24 and the base 22. In an embodiment, the assembly 10 includes a film 30 configured to extend between the sides 14, 16, 18, 20 of the fenestration assembly 10. The film 30 in one or more embodiments of the present disclosure includes a security and/or window film between 1 mil and 30 mil in an embodiment, between 1.5 mil and 18 mil in another embodiment, and between 2 mil and 12 mil in another embodiment. The film 30 has a thickness below 1 mil in an embodiment and a thickness above 30 mil in an embodiment. One non-limiting example of a commercially available product includes Silver 35 window film available from 3M Corporation of Minneapolis, Minn.
The base 22 includes one or more slide channels 58 extending a direction substantially parallel to the film 30 in the embodiment illustrated in FIG. 2. The slide 24 includes one or more tabs 60 extending in a direction substantially parallel to the film 30 such that the one or more tabs 60 is positioned at least partially inside the one or more slide channels 58. The one or more slide channels 58 and the one or more tabs 60 allow the slide 24 to move and/or adjust relative to the base 22 in a direction substantially parallel with the film 30 while being coupled to the base 22, mated with the base 22, or otherwise fixed from movement in a direction not parallel to the film 30.
The primary biasing member 26 includes a linear wave spring in one or more embodiments illustrated herein. In additional embodiments, the primary biasing member 26 includes one or more circular or round wave springs, one or more round or linear sinuous spring, one or more springs of other types, and/or configurations known by those having ordinary skill in the art after reviewing and understanding the present disclosure. Further, after reviewing and understanding the present disclosure, one having ordinary skill in the art will recognize many different biasing structures and methods, such as pneumatic, hydraulic, electrical, and/or magnetic biasing means to name non-limiting examples, and such biasing structures and methods form one or more particular embodiments of the primary biasing member 26 of the present disclosure. Biasing member 26 may be tailored to the particular fenestration assembly embodiment so as to produce desired tautness characteristics in film 30, desired rigidity characteristics in sides 14, 16, 18, 20, and/or desired geometric characteristics in sides 14, 16, 18, 20.
Referring now to FIG. 24, a chart 300 illustrates a force 302 of the primary biasing member 26 relative to a longitudinal point 304 along the primary biasing member 26. The primary biasing member 26 of the embodiment of FIG. 24 is a quantized linear wave spring. Such quantized linear wave springs allow customizable forces to be applied to the assembly 10 to suit the application. As illustrated in FIG. 24, the force 302 is relatively low at a central longitudinal point 304 and relatively high at the outer longitudinal points 304. A force line 308 illustrates the varying force 302 dependent upon the longitudinal point 304. A polynomial trend line 306 illustrates how the force 304 evolves over the length of the primary biasing member 26. Once the primary biasing member 26 is incorporated into the assembly 10, the values of the polynomial trend line 306 will be the measurable values associated with the tension applied to the slide 24 and/or the film 30. Any one or more embodiments of the assembly 10 of the present disclosure may incorporate a custom primary biasing member 26 as described herein to increase tension force at a certain area relative to another area. For example, the primary biasing member 26 described above having the force 302 relatively low at a central longitudinal point 304 and relatively high at the outer longitudinal points 304 may be utilized to maximize tension at areas adjacent the junctions 70 while minimizing the tension at the central locations 38 to prevent twisting, curving, or any other unacceptable deformation of the assembly 10 at the central locations 38.
The assembly 10 further includes a cap 40 coupled to the slide 24 and covering, attaching to, or otherwise being positioned adjacent to at least a portion of the slide 24, as illustrated in the embodiment of FIG. 2. In the embodiment of FIG. 2, the cap 40 moves with the slide 24, is moveable relative to the base 22, and/or is otherwise adjustable within the assembly 10. The cap 40 forms an outer moveable member while the slide 24 forms an inner moveable member in an embodiment. The film 30 is positioned between the slide 24 and the cap 40 to apply tension to the film 30 and/or secure the film 30 to the moveable slide 24/cap 40 subassembly or member 44 illustrated in the embodiment of FIG. 2. Moveable member 44 includes all features of the slide 24 and the cap 40 in an embodiment. In one or more embodiments, the cap 40 further acts as a cover to improve the aesthetic appearance of the assembly and/or protect the slide, base, and primary biasing member 26 from damage and/or dirt or other foreign objects. As shown in FIG. 1A, the base 22 of an embodiment is a single, stationary member while each side 14, 16, 18, 20 includes the moveable members 44.
The slide 24 includes a film attachment point 28 such that, when the primary biasing force 32 acts on the slide 24, the slide 24 is driven, urged, or biased to increase tension of the film 30 attached at the film attachment point 28. The slide 24 includes a film attachment channel 46 configured to receive a film attachment protrusion 48 of the cap 40 in the embodiment illustrated in FIG. 2. In one or more embodiments, the film attachment point 28 and/or the film attachment channel 46 includes an adhesive 50, such as a sprayable glue in one non-limiting example, to hold, secure, or otherwise attach the film 30, at least initially, to the slide 24.
As illustrated in FIG. 1A, the primary biasing force 32 acts against a film tensile force 34 at each of the sides 14, 16, 18, 20 to position the film 30 in the assembly 10 while minimizing wrinkles or other visibility defects or issues. As illustrated in the embodiment of FIG. 2, the base 22 is coupled to the opening 12, such as a window portion in one non-limiting example, with the bracket 36 coupled to the base 22 at an inside space 64 of the window pane 62. In an embodiment, the bracket 36 provides tension to the base 22 in a direction that is opposite and substantially parallel to the film tensile force 34 or a direction of tension on the film 30. The bracket 36 of one or more embodiments includes an adjustable and/or resilient fastener 52 to allow compensation for, or adjustment in response to, an increase or decrease of the film tensile force 34 or any other force that may affect the spacing of the one or more sides 14, 16, 18, 20 at the central location 38 or any other location from the opening 12. In one or more embodiments, the bracket 36 and/or the fastener 52 is integral with or separately coupled to the base 22. In an embodiment, the primary biasing force 32 is greater than or substantially equal to the film tensile force 34 such that the primary biasing force 32 is sufficient to counteract the film tensile force 34 without the presence of or application of any force provided by the bracket 36. In additional embodiments, a force provided by the bracket 36 or another component supplements the primary biasing force 32.
The base 22 of particular embodiments illustrated in the present disclosure may further include one or more end sealing members 54 on an outer side of the base 22 and/or one or more face sealing members 56 disposed between the base 22 and the window pane 62 or other surface. The end sealing member 54 and the face sealing member 56 may be made from a resilient, compliant, and/or otherwise soft material, such as a foam elastomeric or polymeric material in a non-limiting example. As illustrated in one or more embodiments of the present disclosure, the end sealing member(s) 54 are positioned in a slot that may also house the bracket(s) 36. Similarly, the bracket(s) 36 may be positioned in a slot with or without the end sealing member(s) 54.
In an embodiment, the base 22, the bracket(s) 36, and/or another component of the assembly 10 is attached to the window pane 62 with one or more adhesives. In such an embodiment, the base 22, the bracket(s) 36, and/or the assembly 10 is rigidly or securely coupled to the window pane 62 such that the thermal expansion of the base 22, the bracket(s) 36, and/or the assembly 10 generally corresponds with the thermal expansion of the window pane 62. Such an arrangement allows consistent and reliable mounting, sealing, and/or spacing between the window pane 62, the opening 12, and/or the assembly 10. The adhesive includes Loctite® to name a non-limiting example.
The cap 40 and/or the slide 24 of the embodiment shown in FIG. 2 includes one or more nubs or protrusions 42 extending in a direction substantially perpendicular to the film 30 to further increase tension of the film 30. The one or more nubs or protrusions 42 are each considered a secondary biasing member as each supplements the primary biasing member 26 to apply tension to the film 30. Although three protrusions 42 are shown on the cap 40 and two protrusions 42 are shown on the slide 24 in the embodiment of FIG. 2, after reviewing and understanding the present disclosure, one having ordinary skill in the art will recognize that any number of protrusions 42 and any combination or type of protrusions 42 between the cap 40 and slide 24 may be utilized in order to increase tension on the film 30. In an embodiment, the cap 40 and/or the slide 24 includes no protrusions 42.
Referring now to FIG. 3, in the embodiment illustrated, one or more nubs or protrusions 42 are not substantially perpendicular to the film 30. FIG. 3 illustrates an embodiment of the assembly 10 that features a lower profile or thickness. It will be appreciated that the dimensions of any component of the assembly 10 may be optimized or otherwise varied to suit a particular function, fitment, and/or requirement, such as by varying one or more dimensions or physical properties of the one or more protrusions 42, slide 24, base 22, and/or primary biasing member 26 in non-limiting examples. As further illustrated in FIG. 3, the film tensile force 34 provided by the film 30 operates on the same plane as the primary biasing force 32 provided by the primary biasing member 26. In an embodiment, the center of the primary biasing force 32 is located on the same plane as the film tensile force 34 provided by the film 30. In an embodiment, the portion of the film 30 surrounded by the sides 14, 16, 18, 20 is spaced from the window pane 62 upon installation in an embodiment the same distance as the primary biasing member 26 is spaced from the window pane 62 upon installation in the same embodiment. Alignment of the primary biasing member 26 and the film 30 prevents or reduces twisting, torqueing, or creation of one or more moments of one or more of the sides 14, 16, 18, 20 of the assembly 10 or between two or more components, such as between the base 22 and the slide 24, of the assembly 10.
FIGS. 2 and 3 illustrate embodiments of an assembly 10 having the base 22 configured to be positioned adjacent to the window pane 62, i.e., the base 22 is positioned closer to the window pane 62 than the slide 24 or cap 40. An inside space distance 78 is determined by a base film edge 80, as illustrated in the embodiment of FIG. 2. The base film edge 80 of the sides 14, 16, 18, 20 of an embodiment provides a common surface around the assembly 10 to minimize visible imperfections in the film 30. Any embodiment illustrated or described herein may include the base film edge 80. Referring now to FIG. 4, the assembly 10 of an embodiment includes the slide 24 and/or the cap 40 configured to be positioned adjacent the window pane 62 in the inside space 64, i.e., the slide 24 and/or the cap 40 is positioned closer to the window pane 62 than the base 22. It will be appreciated that the embodiment illustrated in FIG. 4 offers an assembly 10 configured to form an air gap 66 between the window pane 62 and the film 3.0 that may be smaller than the air gap 66 formed between the window pane 62 and the film 30 of the embodiments illustrated in FIGS. 2 and 3.
Reference is now made to FIGS. 5 and 6, which illustrate embodiments of the assembly 10 forming multiple air gaps 66 between the window pane 62 and the film 30 and between multiple layers of the film 30. The embodiment of FIG. 5 illustrates the assembly 10 having the base 22 at an internal location of the assembly 10. The slides 24 and/or the caps 40 are disposed outside of the base 22 as illustrated in FIG. 5. The embodiment of FIG. 6 illustrates the assembly 10 having the base 22 at an external location of the assembly 10. One or more slides 24 and/or caps 40 are positioned internally as illustrated in FIG. 6. After reviewing and understanding the present disclosure, one of ordinary skill in the art will recognize that additional layers of the film 30 forming additional air gaps 66 may be incorporated into any of the embodiments disclosed herein to form additional embodiments, and such additional embodiments form part of the present disclosure.
FIG. 7 is a cross-sectional view along lines A-A in FIG. 1A. With reference to FIG. 7 and continuing reference to. FIG. 1, one or more embodiments of the present disclosure include a corner cap 68 at a junction 70 of each of the sides 14, 16, 18, 20. The corner cap 68 is configured to be fixed relative to the base 22 and cover the junction 70. In an embodiment, the corner cap 68 is fixed directly to the base 22, such as with one or more adhesives, fasteners, interference fit, fusing, and/or welding in non-limiting examples. Because the slide 24 and/or the cap 40 is configured to move or otherwise adjust relative to the base 22, the corner cap 68 covers the ends of the moveable slide 24 and/or cap 40 members to protect the components, improve insulation at the ends of the slide 24 and/or the cap 40, and improve the aesthetic appearance of the assembly 10.
Referring now to FIG. 16, an embodiment of the assembly 10 is illustrated. The assembly 10 of FIG. 16 includes the primary biasing member 26 disposed at an inside location of the slide 24 between the base 22 and the slide 24. The cap 40 of the assembly 10 of FIG. 16 pushes, inserts, or otherwise moves the film 30 into the film attachment channel 46 to attach the film 30 to the slide 24. As explained in further detail below, upon attachment of the film 30 to the slide 24, the slide 24 and the cap 40 move inward or toward the film 30 against the primary biasing force 32. One or more protrusions 42 may be provided to further increase tension on the film 30, as explained above.
Referring now to FIG. 17, an embodiment of the assembly 10 is provided. The primary biasing member 26 is disposed between the base 22 and the slide 24, as described in embodiments above.

The slide holder 190 is then removed to allow the primary biasing member 26 to provide tension to the film 30. As with all previous embodiments described herein, any feature(s), structure(s), and/or method(s) of one or more embodiments described in the present disclosure may be utilized in the embodiment of FIGS. 30 and 31.
Referring now to FIG. 35, a method 400 of replacing film in a fenestration assembly according to at least one embodiment of the present disclosure is provided, as may be necessary if the film (such as film 30) becomes damaged. The method 400 of an embodiment includes, at step 402, removing the cap (such as cap 40). At step 404, if necessary a spring pretensioner is installed or inserted or deployed in such a manner as to reduce the tension on the film (such as film 30). As step 406, the old film is removed, and at step 408, new film is installed. In at least one embodiment of the present disclosure, the new film installed at step 408 is mechanically affixed to a field assembly unit that will remain in assembly 10 following replacement of the film. At step 410, if a spring pretensioner was used at step 404, the spring pretensioner is remove such that tension on the film (such as film 30) is restored. At step 412, the cap (such as cap 40) is reinstalled.
The embodiments described and illustrated in the present disclosure reference and relate to the use of the film 30 as a material to be tensioned or otherwise utilized for the embodiments. In the embodiments described and illustrated in the present disclosure, film 30 may be tensioned or tightened to a desired tautness including, by way of non-limiting example, by selection of a biasing member 26 having properties to produce such a desired tautness. In addition, one having ordinary skill in the art, after reviewing and understanding the present disclosure, will recognize that any flexible, flimsy, and/or elastic material, or any material capable of being tensioned or tightened to a desired tautness, may be utilized in place of or in addition to the film 30. However, one having ordinary skill in the art, after reviewing and understanding the present disclosure, will recognize that any flexible, flimsy, and/or elastic material, or any material capable of being tensioned or tightened to a desired tautness, may be utilized in place of or in addition to the film 30. One or more non-limiting examples of such materials include cloth, polymer(s), elastomer(s), and a mesh or chain formed by a metal, polymer, or other material. Additionally, the components of the assembly 10, including but not limited to the base 22, the slide 24, the cap 40, and/or the reinforcement member 240, may be made from a polymer, a metal, a composite, a wood or other natural material, or any other material capable of providing a desired amount of rigidity. Further, components of the assembly 10 may be made from different materials. To illustrate, in one non-limiting example, the base 22 may be made from a metal while the slide 24 may be made from a polymer. In one or more embodiments, if two components are assembled together or otherwise in contact, such as the slide 24 and the cap 40 in two non-limiting examples, and are made from different materials, the coefficient of thermal expansion of the materials is comparable in order to maintain desired fitment and tolerances within the assembly 10 over a wide and varying temperature range.
While the disclosure has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only certain embodiments have been shown and described and that all changes and modifications that come within the spirit of the disclosure are desired to be protected.
