The contents of each application are incorporated herein by reference in their entirety. Background Technology

[0003] Window designs typically have an external nailing fin and are installed from the outside of the building envelope. Two installers work together, one on the inside and one on the outside. Some installers find it easier to break out the window in a relatively clean, flat place on the inside of the building. They then pass the window through the rough opening (RO) to the person on the outside. In some cases, the person on the outside needs to stand on a ladder, which can make the installation very complicated. The installer on the inside centers the window in the RO and inserts shims to level, plumb, and square it while the installer on the outside holds the window. After the window is installed accurately, the installer on the inside secures the window in place while the installer on the outside drives nails or screws through the external nailing fin to secure it. If it is a vented window, the sash is opened to check the functional operation. The installer on the inside continues to inject expanding foam in the gap between the frame of the window and the RO to create an internal air seal. Meanwhile, the installer on the outside applies 3-4 inch wide flashing tape on the jamb and on the top of the window.

[0239] Those skilled in the art will readily understand that various aspects of this disclosure can be implemented by any number of methods and apparatuses configured to perform the intended functions. It should also be noted that the accompanying drawings referenced herein are not necessarily drawn to scale, but may be enlarged to illustrate various aspects of this disclosure, and in this regard, the drawings should not be construed as limiting.

[0240] Description of various embodiments

[0241] Various concepts in this patent specification relate to installation systems and methods for window opening units, such as those for windows and doors. Some features of such systems and methods include one or more of the following: configured to be installed from the inside of a building structure or wall into a rough opening (RO); eliminating or reducing the need for side posts and / or window sill gaskets; pre-applied window sill gaskets (e.g., factory application); pre-applied head stabilizers and / or side post stabilizers for self-stabilization in the rough opening while leveling, ducting, squaring, and / or anchoring the window opening unit; measuring the inner surface of the rough opening to obtain more precise trim (e.g., drywall and / or finish) offsets; utilizing pre-applied (… For example, anchoring clips for securing internal units (e.g., for factory applications); minimal or no fasteners used on the outside of the window unit; pre-attached external waterproof barriers (e.g., pop-out wings) for factory applications; storable and deployable external waterproof barriers (e.g., secured by removable packaging clips for transport / installation); ease of use with standard waterproof tape methods; configured for installation by a single person / installer; internal and external installation tasks can be performed at different times (e.g., a considerable time interval between the two types of tasks).

[0242] In various examples, the window unit (e.g., window unit 10) includes features that facilitate installation of the window unit from the inside of the rough opening using a method easily implemented by a single installer. Specifically, the window unit according to various examples includes a retaining system coupled to a frame of the window unit, which is operable to apply a retaining force to the window unit to maintain positive engagement of the window unit with the rough opening frame and to prevent the window unit from being pulled out of the rough opening when inserted from the inside of the rough opening. The retaining system can be operated to keep the window unit stationary in the rough opening without using fasteners to secure the window unit to the rough opening frame. The window unit may include an engagement system coupled to a frame that is configured to positively engage with the inner surface of the rough opening frame when the window unit is inserted from the inside of the rough opening. Conversely, when the window unit is inserted into the rough opening from the inside, the aforementioned retaining system can be operated to maintain the positive engagement between the retaining system and the rough opening frame without the need for fasteners to secure the window unit to the rough opening frame.

[0243] In this way, one person can insert the window unit into the rough opening (RO) from the inside without a second person holding the window unit against the rough opening frame or otherwise assisting in maintaining the window unit's position within the rough opening (RO). This holding feature also frees up the installer's hands to perform installation processes such as securing the window unit to the rough opening with fasteners like nails or screws, and / or leveling, installing pipes, and adjusting the squareness of the window unit within the rough opening (RO).

The window unit 10 includes a frame 30, which includes a head 32, a first side post 34, a second side post 36, and a windowsill 38. The window unit 10 also includes a panel unit or glass unit 40 supported by the frame 30. The glass unit 40 can be any of a variety of configurations, but in some embodiments it is an insulated glass (IG) unit. As shown, the window unit 10 is configured as a casement window, but various configurations (fixed, single-hung, double-hung, awning, or others) are also conceivable.

[0247] As shown in the figure, frame 30 can be a wood frame (e.g., aluminum-clad wood) design. However, frame 30 can also be made of vinyl, fiberglass, or other materials. Frame 30 also includes an outer perimeter P and has a front or inner surface 42 and a rear or outer surface 44. FIG. 3 ).

[0248] like FIGS. 1-3 As shown, the window opening unit 10 includes one or more mounting features to facilitate installation of the window opening unit 10. For example, as shown, the window opening unit 10 may include one or more of the following mounting features: an anchoring clip system 100 (also referred to as a joining system), a window sill gasket system 200, etc.FIG. 2 ) and the installation of stabilizer system 300 ( FIG. 1 ) retention system, weather sealing system 400 ( FIG. 3 ) and regulating system 500 ( FIG. 1 ).

[0249] ANCHORING CLIP SYSTEM

[0250] like FIG. 1 As shown, the anchoring clip system 100 (also referred to as the engagement system) includes a plurality of anchoring clips 102 fixed to the outer periphery P of the frame 30. Specifically, the anchoring clips 102 are coupled to the first side post 34 and the second side post 36 (e.g., three for each side post). As shown, the anchoring clip system 100 includes six (6) anchoring clips 102, but more (e.g., 6, 8, 10, 12, etc.) or fewer (e.g., 4 or 2) anchoring clips 102 may also be considered. Typically, embodiments will include at least four (4) anchoring clips 102, two upper anchoring clips 102 facing the head 32 and two lower anchoring clips 102 facing the windowsill 38. As the size of the window opening unit 10 increases, more anchoring clips 102 may be required to help ensure accurate anchoring of the window opening unit 10, a function which will be described in more detail below.

[0251] In use, each anchor clip 102 can be positioned at a desired or measured depth for installation (e.g., to accommodate side column extensions and / or drywall rotation). The anchor clip 102 can help measure the distance between the window unit 10 and the inner surface of the building's rough opening (RO). This measurement capability helps ensure proper offset of drywall thickness or other wall features and helps eliminate or reduce problems such as the side column extensions of the window unit 10 "protruding" or "recessed" from the inner surface of the finished wall surface (e.g., inner drywall). Installation using the anchor clip 102 results in flush side column extensions relative to the inner surface of the wall (e.g., inner drywall), making the installation of trim pieces (e.g., sleeves) of the window unit 10 more efficient for subsequent detailed steps (e.g., wood finishing).

[0252] In some embodiments, the anchor clip 102 is initially provided to the installer in a retracted configuration (e.g., during transport or delivery to the installer), such as... FIG. 4As shown. An installer (not shown) removes, flips, or rotates a portion of the anchor clip 102 and reinserts the portion of the anchor clip 102 to the desired total depth by pushing to engage the retaining features (e.g., slots) of the anchor clip 102. In many examples, the installer can remove and reinsert the portion of the anchor clip 102 without the use of tools. As mentioned above, although fewer or more anchor clips 102 are conceivable, a typical or average-sized window unit 10 will have four (4) to six (6) anchor clips 102. As part of the installation process, the installer (not shown) removes the anchor clips 102 from... FIG. 4 The position shown is flipped (axially rotated) to FIGS. 1-3 The position shown is part of the installation preparation work. In some designs, the anchor clip 102 can be adjusted for different installation depths (e.g., to accommodate 1 / 2 inch or 5 / 8 inch internal drywall thickness).

[0253] The anchor clip 102 may also have different adjustment settings or features at different portions of it, allowing the anchor clip 102 to be flipped to accommodate different (e.g., greater) adjustability. For example, a portion of the anchor clip 102 (e.g., a leg) may have a first set of adjustment features (e.g., to accommodate 1 / 2-inch or 5 / 8-inch internal dry wall thickness offsets), and another portion of the anchor clip 102 (e.g., another leg) may have a second set of adjustment features (e.g., multiple slots for 1 / 8-inch incremental adjustments over a desired distance range).

[0254] Considering the above, such as FIGS. 1-4 As shown, each anchor clip 102 can be substantially similar to each other and can be described cumulatively in conjunction with the first anchor clip 102. FIG. 5 An exemplary design of the anchoring clip 102 (first anchoring clip 102a) is shown in a perspective view.

[0255] like FIG. 5 As shown, the first anchoring clip 102a includes a perimeter P configured to connect to the frame 30. FIG. 1The support shelf 110 and the connecting shelf 112 are described. In some embodiments, the support shelf 110 can be attached to the frame 30 by adhesion to it, or the support shelf 110 can be attached to the frame 30 by fasteners. However, other attachment methods are contemplated, including adhesives, thermal bonding, integral molding, or other methods. The connecting shelf 112 can be secured to the support shelf 110 such that the connecting shelf 112 can be switched between a first retracted configuration and a second mounting configuration. The first anchoring clip 102a may optionally be made of stamped sheet metal (e.g., galvanized steel) or other suitable material or manufacturing method. Although the support shelf 110 is shown as a separate component from the frame 30 (e.g., pre-attached at the factory or elsewhere away from the installation site), the support shelf 110 or its features may be integrally formed into the frame 30 as part of a manufacturing process (e.g., molding, machining, milling, etc.).

[0256] FIG. 6 and FIG. 7 This is a separate isometric view of a support shelf 110 according to some embodiments. As shown, the support shelf 110 includes a back panel 120 and a receiver 122.

[0257] FIG. 8 An isometric view of a backplate 120 according to some embodiments is shown. The backplate 120 may optionally be attached to the receiver 122 using riveting, welding, adhesives, co-casting / molding, or other methods. Although shown, in some embodiments, the backplate 120 may be omitted from the support shelf 110. FIG. 9 An isometric view of receiver 122 according to some embodiments is shown.

[0258] As shown, the support shelf 110 defines a retaining recess 130 for receiving the connecting shelf 112. The support shelf 110, and more specifically the receiver 122, has a retaining lip 132 and a retaining member 134.

[0259] The retaining lip 132 serves as a guide and retainer beneath which the connecting shelf 112 can slide. The retaining lip 132 and an optional backplate 120 define a retaining recess 130. Without the backplate 120 or similar structure, the retaining recess 130 may be defined by the portion of the receiver 122 and the window unit 10 located below the first anchoring clip 102a. The retaining lip 132 may define a first side 132a and a second side 132b facing the edge of the retaining recess 130 for securing corresponding portions of the connecting shelf 112.

[0260] The retaining member 134 may be formed from a portion of the retaining lip 132. For example... FIG. 9As shown, the retaining lip 132 includes a pair of cutouts 140 forming a flexible protrusion 142 of a retaining member 134 that can be resiliently deflected. The retaining member 134 also includes a release handle 144 projecting from the flexible protrusion 142. FIG. 7 As shown, the retaining member 134 also includes one or more claws 150, also referred to as teeth 150 or slots 150, for engaging with the connecting shelf 112. For example, the release handle 144 may be oriented to project toward the front or inside of the frame 30, and the release handle 144 is operable to lift off the frame 30 to actuate or release the retaining member 134 from the first slot 174 (e.g., as shown). FIG. 10 (As shown).

[0261] In use, the flexural protrusion 142 can deflect outward to release or translate one or more jaws 150 in the outward direction, and once released, the flexural protrusion 142 will elastically flex back to its original position. FIG. 8 As shown, the backplate 120 may include receiving slots 152 for receiving the ends of one or more claws 150. These receiving slots 152 may enhance the overall resistance of the retaining member 134 to pull-out forces when it is not released.

[0262] FIG. 10 An isometric view of the connecting shelf 112 is shown. As shown, the connecting shelf 112 includes a first leg 114 and a second leg 116 extending from the first leg 114 and having an angular offset (e.g., a generally orthogonal angle). The first leg 114 is configured to be slidably received by a support shelf 110. The second leg 116 is configured to be secured to a frame surrounding a rough opening (RO) in the building structure using one or more fasteners (e.g., nails or screws). If desired, the functions of the two legs 114, 116 can be interchanged (both the first leg 114 and the second leg 116 are configured to be slidably received by the support shelf 110 and are both configured to be secured to a frame surrounding a rough opening (RO) (e.g., see...). FIG. 13 (Design shown). As shown, the first leg 114 and the second leg 116 may have one or more supports 160 or other reinforcing features to help strengthen the first leg 114 and the second leg 116 to prevent relative flexing.

[0263] The second leg 116 of the connecting shelf 112 may optionally include a release hole 162 extending through the thickness of the second leg 116. (See reference...) FIG. 5 As can be seen, the release handle 144 can be accessed from inside or on the front side of the window opening unit 10 via the release hole 162 (e.g., using a screwdriver or other tool). As shown, the release hole 162 can also extend into the first leg 114. The release hole 162 is typically located at the intersection or corner between the first leg 114 and the second leg 116.

[0264] As shown, the first leg 114 has: a first edge 166 and a second edge 168 opposite to each other; and a front end 170 located at one end of its length, the front end 170 including an insertion guide 172 in the form of a rounded protrusion. When the front end 170 is inserted into the support shelf 110, the insertion guide 172 can help align and insert the first leg 114 into the support shelf 110. In some embodiments, including two reversibly functional legs 114, 116, both the first leg 114 and the second leg 116 may include the insertion guide 172. The first leg 114 also has one or more slots 174 located at one or more longitudinal positions along the length of the first leg 114 (a pair of first slots 174a are shown). As shown, the one or more slots 174 may take the form of a slot through the thickness of the first leg 114, but other constructions (e.g., partial depth slots) are also possible. When the connecting shelf 112 is in the installed state, one or more longitudinal positions of one or more slots 174 are selected based on the desired offset of the second leg 116 from the front end 42 of the frame 30. For reference, FIG. 10 The possible locations of a pair of second card slots 174b are usually indicated by dashed lines.

[0265] The second leg 116 has one or more fastener holes 180 operable to receive one or more fasteners (not shown), such as screws or nails. The second leg 116 also has a length selectable to ensure sufficient overlap with the frame surrounding the rough opening (RO) (not shown), thereby ensuring that the fasteners can engage with the frame. The fastener holes 180 may be recessed or countersunk to allow for flush mounting of screw heads. In this way, the fasteners will not interfere with drywall or other wall treatment fixtures mounted on the second leg 116. The connecting shelf 112 can be fastened to and removed from the rough opening (RO) without damaging its components. The connecting shelf 112 can be removed from the rough opening (RO) using a standard tool (e.g., a screwdriver). One or more fastener holes 180 may be positioned at different lengths along the second leg 116 to accommodate differences in drywall thickness and length differences in the space between the frame 30 and the rough opening (RO).

[0266] exist FIG. 5 In the figure, the first anchoring clip 102a is in the installed state, wherein the second leg 116 of the connecting shelf 112 protrudes outward relative to the supporting shelf 110. As shown, the first leg 114 is fully inserted into the retaining recess 130, such that the retaining lip 132 extends over the first leg 114. As shown, the first side 132a of the retaining lip 132 ( FIG. 9 ) and the second side 132b (FIG. 9 Positioned toward the edge of the retaining notch 130 and secured to the edge of the connecting shelf 112. One or more claws 150 FIG. 7 The claws, also known as teeth 150, engage in one or more slots 174 (first pair of slots 174a) of the first leg 114. One or more claws 150 may also optionally extend to a receiving slot 152 of the backplate 120. FIG. 8 This helps to lock the connecting shelf 112 into place. To release the claw 150 from the slot 174, the user can press or lift the release handle 144. FIG. 7 And flex the flexure plate 142, thereby lifting the claw 150 from the slot 174.

[0267] like FIG. 1 , FIG. 2 and FIG. 4 As shown, a plurality of anchor clips 102 are secured to the frame 30 at a desired depth from the front 42 of the frame 30 (e.g., the support shelf 110 may be mounted flush or substantially flush with the front 42 of the frame 30). The plurality of anchor clips 102 may optionally be secured to the top and bottom of the first side post 34 and the second side post 36, respectively, wherein two (2) additional anchor clips 102 are located at intermediate positions on each side post 34, 36. In some embodiments, the plurality of anchor clips 102 may be spaced apart at substantially similar intervals along the first side post 34 and the second side post 36, respectively.

[0268] In such FIGS. 1-3 In the installation configuration shown, the second leg of each connecting shelf includes the second leg 116 of the connecting shelf 112. FIG. 5 ) protrudes outward from the center of frame 30, and from the perimeter P of frame 30. FIG. 1 (Protrudes outwards.) For example... FIG. 4 As shown, in the retracted configuration, the second leg of each anchoring clip 102, including the second leg 116 of the connecting shelf 112 ( FIG. 5 From the perimeter P ( FIG. 1 The second leg 122 protrudes inward and toward the center of the frame 30. In some embodiments, when the connecting shelf 112 is in a retracted configuration, the second leg 122 extends substantially flush with the front or inner surface 42 of the frame 30.

[0269] FIG. 11AAnother design of anchor clip 102 in the form of anchor clip 102' is shown. Anchor clip 102' may include features similar to those of the first anchor clip 102a. As shown, anchor clip 102' has multiple pairs of slots 174' along the length of the first leg 114' and multiple pairs of slots 175' along the length of the second leg 116'. Thus, the first leg 114' and the second leg 116' can be reversibly positioned in the support shelf 110' of anchor clip 102'. In some examples, the multiple pairs of slots 174' allow retaining member 134' to be releasably locked at a first offset distance and a second offset distance from the front of frame 30 as needed. For example, the second offset distance may be approximately 0.125 inches greater than the first offset distance, such that anchor clip 102' is configured to accommodate different installation depths, such as to accommodate different thicknesses of wall coverings (e.g., drywall) or window unit features (e.g., side-post extension window units or handles). In some embodiments, the anchor clip 102' includes a built-in groove along the length of the first leg 114' or the second leg 116', serving as a gauge for determining the accurate installation depth. Any of a variety of slot configurations may be present. For example, multiple pairs of slots 175' allow for adjustability in any desired increment (e.g., 0.0625 inches, 0.125 inches, or others) across multiple depth ranges. In other embodiments, the number of multiple pairs of slots 175' may be minimized to reduce installation errors.

[0270] In some embodiments, the anchor clip 102' may include one or more recessed lines or notches 179' within the width of the anchor clip 102'. The notches may extend between multiple pairs of slots 175'. The notches 179' may be located on either the first leg 114' or the second leg 116', and may allow installers to shorten the length of the anchor clip 102'. For example, after installers re-insert the connecting shelf 112' into the support shelf 110', the connecting shelf 112' may extend too far from the frame 30, which could affect the installation of features around the window unit 10, such as additional drywall or paint. To shorten the connecting shelf 112', installers may bend the first leg 114' or the second leg 116' back and forth along the notches 179', causing a portion of the first leg 114' or the second leg 116' to break off and be removed. Shortening the connecting shelf 112' may further allow for the adjustability of the anchor clip 102'. In some examples, the window unit 10 is provided with a set of anchor clips (not shown) of different constructions, which have different lengths and / or slot positions corresponding to different installation depths. The multiple anchor clips of different constructions may be color-coded, marked with numbers, letters or symbols, or otherwise identified to facilitate the user in selecting the appropriate size shelf for the specific installation depth of the window unit 10 in the rough opening (RO).

[0271] FIGS. 11B-11E Another design of the anchor clip 102 in the form of anchor clip 102” is shown. The anchor clip 102” may include features similar to those of the first anchor clip 102a or anchor clip 102’. The anchor clip 102” shows various engagement / adjustment features that can be interchanged between the support shelf and the connecting shelf assembly. For example, as shown in the anchor clip 102”, a plurality of slots 178” are located on the support shelf 110” of the anchor clip 102”, rather than on the first leg 114” or the second leg 116” of the anchor clip 102” as shown in other embodiments.

[0272] like FIG. 11B As shown, the anchoring clip 102” may include a connecting shelf 112 located between the back plate 120” and the support shelf 110”. The back plate 120” and the support shelf 110” may define a retaining notch to receive the connecting shelf 112”. Although shown in some embodiments, the back plate 120 may be omitted. In some embodiments, the frame 30 may alternatively serve as the back plate 120”. FIG. 11C The anchor clip 102 with the backplate 120” removed is shown.

[0273] like FIG. 11E As shown, the support shelf 110” may include a plurality of slots 178” or a row of slots 178” along the length of the support shelf 110”. Furthermore, the slots 178” may be formed as recesses (e.g., rather than through holes) and include a serrated or sawtooth profile for better engagement. The serrated or sawtooth profile can accommodate the swinging of the connecting shelf 112” along a row of slots 178” to allow the connecting shelf 112” to advance to a desired position.

[0274] like FIG. 11C and FIG. 11D As shown, the support shelf 112” may include a retaining member 134” located on the first leg 114” of the anchoring clamp 102”. The retaining member 134” may include one or more claws 150”, also referred to as teeth 150” or slots 150”, for engaging with the support shelf 110”, particularly with slots 178”. The teeth 150” or slots 150” may be sized to “lock” within a recess defined by slots 178” to hold the connecting shelf 112” in a desired position. In the illustrated embodiment, as FIG. 11DAs shown, the retaining member 134" includes a guide 144" similar to the release handle 144", which can be configured to assist a tool (e.g., a screwdriver) in releasing the pawl 150" from the slot 178" below the retaining member 134" for adjustment purposes. Alternatively or additionally, the guide 144" can be configured as a handle similar to the handle 144", wherein the guide 144" can be pressed down to achieve a rocker effect to lift the pawl 150" from the slot 178" for adjustment purposes.

[0275] Although not shown, similar to other embodiments, it is conceivable that the second leg 116” of the anchor clip 102” includes a second retaining system (e.g., similar to retaining system 134) such that the first leg 114” and the second leg 16” can be reversibly positioned in the support shelf 110” and engage with a plurality of slots 178”. In some examples, the plurality of slots 178” allow the retaining member 134” to be releasably locked at multiple offset distances from the front of the frame 30 as needed. For example, this can accommodate wall coverings of different thicknesses (e.g., drywall) in increments including, but not limited to, 0.0625 inches, 0.125 inches, or others. Various slot configurations can be present to achieve any desired increment.

[0276] SILL SPACER SYSTEM

[0277] FIGS. 12-14 The pre-spaced feature (e.g., "pre-spaced window") of the window unit 10 in the form of a window sill gasket system 200 at the window sill 38 is shown. FIGS. 12-14A bottom view, a perspective bottom view, and an enlarged side view of the window opening unit 10 are shown, respectively. In some embodiments, the window sill pad system 200 provides a convenient mechanism for positioning and leveling the window opening unit 10 within the rough opening (RO). In some embodiments, the window sill pad system 200 facilitates centering of the window opening unit 10 within the rough opening (RO) by reducing friction between the frame 30 of the window opening unit 10 and the rough opening (RO) during relative movement. The window sill pad system 200 establishes a gap between the rough opening (RO) and the window sill 38 to facilitate easier adjustment of the window opening unit 10's positioning by installers (e.g., by inserting a pry bar or other tool under the window sill 38 of the window opening unit 10 for lifting and leveling). Standard wooden mortises or other mortises can slide under the window sill pad system 200 to keep the window opening unit 10 flat within the rough opening (RO). As described below, the window sill gasket system 200 can be adapted to prevent damage to the bottom of the window sill waterproofing tape or rough opening (RO) frame, and other features (e.g., the window sill gasket system 200 may have a “line contact” and / or be rounded to avoid damage). Furthermore, due to the pre-attached nature of the window sill gasket system 200, the number of additional separately installed grout pieces required (e.g., conventional wooden grout pieces, polymer grout pieces, or others) can also be reduced.

[0278] The window sill gasket system 200 includes one or more window sill gaskets 202, such as a pair of window sill gaskets 202, attached at the window sill 38 to the bottom of the frame 30. FIG. 15A , FIG. 16A and FIG. 17A One of the window sill gaskets 202 according to some embodiments is shown. FIG. 15A It is an isometric view. FIG. 16A Is it a side view or an end view? FIG. 17A This is a bottom view. As shown, the window sill gasket 202 includes a circular lower contact surface 210. If desired, the lower contact surface 210 may have a flat apex 212. In any case, as shown, when viewed from the end, the window sill gasket 202 defines a smooth profile, and the window sill gasket 202 has a circular profile.

[0279] In some embodiments, one or more window sill pads 202 may comprise a material or coating having a bright color, fluorescent or fluorescent properties and / or reflective properties. These features of one or more window sill pads 202 may contrast with the frame 30 to help installers quickly locate one or more window sill pads 202 during the installation of the window opening unit 10.

[0280] The windowsill gasket 202 may also optionally include an upper attachment surface 216 having one or more protrusions 218 and / or grooves 220 configured to engage with features within the bottom of the windowsill 38 to facilitate attachment thereto. In some embodiments, the bottom of the windowsill 38 includes one or more longitudinal protrusions and / or grooves that receive and complementarily engage with the upper attachment surface 216. FIG. 12 and FIG. 17C Additionally or alternatively, the window sill gasket 202 may include one or more holes to receive fasteners (e.g., screws) passing through it, thereby attaching the window sill gasket 202 to the window sill 38. One or more holes may be varied to accommodate other fastener types and shapes, including but not limited to staples, to attach the window sill gasket 202 to the window sill 38. In other embodiments, the window sill gasket 202 may be adhesively attached to the window sill 38. The window sill gasket 202 may optionally define a preselected gap width from the rough opening (RO). For example, each window sill gasket 202 may define a maximum thickness of approximately 1 / 4 inch. In some embodiments, the window sill gasket 202 defines a maximum thickness of at least 1 / 4 inch, although various sizes are contemplated, including thinner sizes.

[0281] like FIGS. 12-14 As shown, one or more window sill gaskets 202 can be pre-attached to the window opening unit 10 (e.g., at the manufacturing site) before any field installation steps can begin. As shown, the window sill gaskets 202 are positioned entirely between the front 42 and rear 44 of the frame 30. At least in this way, the window sill gasket system 200 leaves a continuous gap (e.g., approximately 1 / 4 inch) between the bottom of the frame and the rough opening (RO) at the window sill 38. This allows for better formation of continuous insulation and / or sealing at the window sill 38 (e.g., using sprayed foam or other materials as needed). In some embodiments, the pair of window sill gaskets 202 are spaced apart from each other and spaced apart from the first side 24 and the second side 26 of the window opening unit 10.

[0282] like FIG. 12 and FIG. 13 As shown, each window sill pad 202 can extend longitudinally between the first side 24 and the second side 26 of the window opening unit 10. According to the arrangement, the window sill pad 202 is offset relative to the back or outside 44 of the frame 30 toward the front or inside surface 42 of the frame 30. FIG. 12 and FIG. 14As shown, glass unit 40 defines a center of gravity W, which generally corresponds to the plane on which glass unit 40 is mounted in frame 30. A window sill pad 202 is offset along an inclined axis T from the center of gravity W toward the inner surface 42, causing the window opening unit 10 to tend to tip over or fall onto the window sill pad 202 in the outward direction. At least in this way, when the window opening unit 10 rests on the window sill pad 202, the window opening unit 10, under its own weight, presses the anchoring clip system 100 against the frame around the rough opening (RO). According to some embodiments, this result helps to facilitate a situation where, during installation, an installer (not shown) does not need to press the window opening unit 10 or hold it in place. Or in other words, the window opening unit 10 achieves self-balancing within the rough opening (RO), such that the window opening unit 10 remains within the rough opening without falling inward or outward.

[0283] FIG. 15B and FIG. 16B Another design of the window sill gasket 202 in the form of window sill gasket 202' is shown, wherein FIG. 15B It is an isometric view. FIG. 16B This is an end view. (And...) FIG. 15A The design is similar. FIG. 15B and FIG. 16B The window sill gasket 202' includes a circular lower contact surface 210'. If desired, the lower contact surface 210' may have a flat apex 212'. In any case, as shown, when viewed from the end, the window sill gasket 202' has a smooth profile and a circular profile. FIG. 15B and FIG. 16B The window sill gasket 202' may also optionally include an upper attachment surface 216' having one or more protrusions 218' and / or grooves 220' configured to abut against the bottom of the window sill 38 to facilitate attachment thereto. Similar to the previously described design, the window sill gasket 202' may optionally define a preselected gap width from the rough opening (RO) (e.g., about 1 / 4 inch, defining a maximum thickness of at least 1 / 4 inch).

[0284] FIG. 15C , FIG. 16C and FIG. 17C Another design of the window sill gasket 202 in the form of window sill gasket 202” is shown, in which FIG. 15C It is an isometric view. FIG. 16C It is an end view. FIG. 17C It shows FIG. 15C The window sill gasket 202” is connected to the window sill 38 of the window opening unit 10. FIG. 15A and FIG. 15B The design is similar. FIG. 15C and FIG. 16CThe window sill gasket 202" includes a circular lower contact surface 210". If desired, the lower contact surface 210" may have a flat apex 212". In any case, as shown, when viewed from the end, the window sill gasket 202" defines a smooth profile and has a circular profile. FIG. 15B and FIG. 16B The window sill gasket 202” may also optionally include an upper attachment surface 216”, which has one or more protrusions 218” and / or grooves 220” configured to abut the bottom of the window sill 38 for attachment thereto. As shown, the upper attachment surface 216” defines a layered or staggered upper surface. Similar to the previously described design, the gasket 202” may optionally define a preselected gap width from the rough opening (RO) (e.g., approximately 1 / 4 inch, defining a maximum thickness of at least 1 / 4 inch). FIG. 17C As shown, the layered or staggered profile of the upper attachment surface 216” helps to facilitate the engagement of the window sill gasket 202” with the stepped, angled or sloping window sill profile for secure attachment.

[0285] STABILIZER SYSTEM

[0286] like FIG. 1 As shown, the mounting stabilizer system 300 includes at least one retainer 302, also referred to as a stabilizer clip 302. The retainer 302 is optionally applied prior to any mounting steps and is located remotely from the mounting site (e.g., at a manufacturing plant). As shown, the retainer 302 is located at the head 32 of the window unit 10. The retainer 302 may optionally be formed as a bent, stamped, and / or cut metal piece.

[0287] According to some embodiments, FIG. 18A It is an isometric view or a three-dimensional view. FIG. 19A This is a side view of a design for retainer 302. FIG. 18A and FIG. 19A The retainer 302 is shown in its natural, unbiased state. Typically, the retainer 302 is configured to allow the frame 30 to move along the first insertion direction D1 (…). FIG. 20A The insertion structure (not shown) is inserted into the rough opening (RO) and prevents the frame 30 from being pulled out in the second pull-out direction D2. FIG. 21A Pull it out of the opening.

[0288] like FIG. 19A As shown, the retainer 302 includes components configured to be fixed to the frame 30 ( FIG. 1The device comprises a seat 310 and a plurality of flexible arms 312 extending from the seat 310, each flexible arm including an engagement feature 316 at its end. In some embodiments, the seat 310 may be attached or secured to the frame 30 by adhesion to it, or by fasteners. However, other attachment methods are also contemplated. FIG. 18A As shown, the plurality of flexible arms 312 includes a first flexible arm to a fourth flexible arm, although any number of flexible arms (one, two, three, five, etc.) can be envisioned. As shown, the plurality of flexible arms 312 may have different lengths to accommodate different spaces or a range of spatial dimensions between the frame 30 and the head of the rough opening (RO).

[0289] The retainer 302 may optionally include a strap member (e.g., similar to) extending rearward from the seat 310. FIG. 18B (The belt member 302a). The belt member may optionally include a plurality of fastener holes for receiving one or more fasteners (e.g., screws or nails). The belt member is generally capable of bending between a retracted configuration and an extended configuration, in which the belt member extends toward the center of the window unit 10, and in which the belt member extends upward away from the center of the window unit 10.

[0290] like FIG. 18A As shown, the engagement features 316 of the multiple flexible arms 312 each include engagement edges 316a ( FIG. 18A The engagement edge 316a includes one or more sharp edges or teeth (e.g., two protruding teeth) for biting, for friction engagement of the head H of the frame of the rough opening (RO). FIG. 20A In other words, engagement feature 316 includes one or more teeth configured to bite into the material defining the rough opening (RO) as the frame moves in an inward direction (e.g., D2). In some embodiments, the sharp edge or tooth is a cutting edge of the material (e.g., a metallic material) that may become sharp with or without additional mechanical sharpening.

[0291] like FIG. 20A and FIG. 21A As shown, in various embodiments, during insertion of the frame 30 along the first insertion direction D1, one or more flexible arms 312 of the retainer 302 (e.g., the first flexible arm 312a if there is a large gap between the head H and the frame 30, or all four flexible arms 312 if there is a very small gap between the head H and the frame 30) bend or deflect in the first flexure direction, and as the frame 30 moves along the second pull-out direction D2, the flexible arms 312 flex in the second flexure direction to resist movement of the frame 30 along the second direction D2 (e.g., toward the inward side).

[0292] In some embodiments, the retainer 302 is configured to be fixed in a constrained state (downward compression) such that the retainer 302 is flattened against the frame 30. A fastening member (e.g., tape) can be used to hold the retainer 302 in the constrained state. The fastening member can be removed to release the retainer 302 into an extended state, such that the retainer 302 protrudes outward from the frame 30 (e.g., to fit with...). FIG. 1 (Similar to the method shown).

[0293] FIG. 20A This is a schematic diagram showing the engagement of retainer 302 with the head H of the frame of the rough opening (RO). For example... FIG. 20A As shown, the window opening unit 10 is configured such that when the window opening unit 10 slides in the external direction or the first insertion direction D1 and is inserted from the inside of the rough opening RO, the retainer 302, specifically the flexible arm 312, acts as a spring body. This spring body deflects and compresses in height when the engagement edge 316a of the engagement structure 316 bites into the head H. During installation, the retainer 302 can automatically unfold to abut against the head H of the rough opening (RO) frame without the need for operator intervention. FIG. 20A As shown, during compression, the engaging member 316 slides against the head H. This compression and sliding action allows the retainer 302 and therefore the window opening unit 10 to be inserted in the external direction or the first insertion direction D1 with a first relatively low insertion resistance. In various embodiments, the engaging edge 316a does not bite or otherwise prevent sliding as it slides past the head H. This may be due to the angle of the engaging edge 316a. The insertion force or the force required for movement in the first direction D1 may be, for example, 1 pound or less, greater than 1 pound, greater than 10 pounds, or greater than 15 pounds. Typically, the window opening unit 10 tilts or tilts backward in the external direction during insertion in the first direction D1 and enters final positioning.

[0294] FIG. 21AThe diagram illustrates how the retainer 302 deforms and resists movement as the window unit 12 and retainer 302 move in the inward direction or the second pull-out direction D2. As shown, the flexural arms 312 rotate rearward or spring upward (or downward, not shown) as the engagement edges 316a of the engagement features 316 engage in the head H and prevent the engagement features 316 from sliding relative to the head H. In some examples, the flexural arms 312 bend or flex due to this movement. The pull-out force or tilting force or the force required for movement in the second direction D2 after positioning can be, for example, 1 pound or less, greater than 1 pound, 10 pounds or more, at least 15 pounds, or 15 pounds or more. In some examples, the pull-out force is 80 pounds or more, or about 88 pounds. Generally, a higher required pull-out force or tilting force (e.g., compared to the insertion force) helps ensure that the window unit 10 remains in place after insertion into the rough opening (RO) to allow for subsequent leveling and / or securing procedures. The ability of retainer 302 to resist movement in the second pull-out direction D2 can help prevent window 10 from falling inward from rough opening (RO).

[0295] In this embodiment, the insertion force, extraction force, or holding force can be determined using a force gauge placed perpendicular to a vertical plane of the window opening unit 10, located on the outside of the window opening unit 10, approximately eight inches from the top of the window opening unit 10 along its vertical centerline. For the holding force, the force gauge can be pushed inwards until the window opening unit 10 is pressed into a rough opening (RO) to achieve maximum holding force.

[0296] When the window opening unit 10 is inserted into the rough opening (RO), the retainer 302 compresses and engages (e.g., bites) into the head H of the rough opening (RO), and optionally applies a downward force to the window opening unit 10. The function of the retainer 302 can be to help stabilize the window opening unit 10 in the rough opening (RO) to help ensure that the window opening unit 10 does not fall back inward (i.e., resist pull-out along the second pull-out direction D2). This self-holding or stabilizing feature helps allow a single installer (not shown) to perform leveling and centering tasks without holding the window opening unit 10 in the rough opening (RO). If present, the windowsill gasket system 200 can also help achieve this self-holding / stabilizing function. As shown, the retainer 302 is compressible, and therefore can be adjusted and adapted to a range of typical gap dimensions between the head 32 and the head H of the rough opening (RO). In addition, the retainer 302 has lateral flexibility and is made of a spring-like material, which allows for left-right adjustment and leveling of the window unit 10 within the rough opening (RO) without significantly hindering these processes.

[0297] In some embodiments, the window opening unit 10 can be pulled out of the rough opening (RO) without damaging the retainer 302. The window opening unit 10 can be lifted upwards via the windowsill 38 (e.g., manually or with a tool), causing the retainer 302 to compress further toward the head H of the frame of the rough opening (RO). The window opening unit 10 can then be rotated out of the rough opening (RO) and toward the inward. This movement allows for controlled release of the window opening unit 10 from the rough opening (RO) without the need for specialized tools and without damaging the retainer 302. The retainer 302 can be reused when the window opening unit 10 is reinstalled into the rough opening (RO).

[0298] FIG. 18B It is an isometric view or a three-dimensional view. FIG. 19B This is a side view of another design of the retainer 302 in the form of retainer 302', also known as stabilizing clip 302', according to some other embodiments. FIG. 18B and FIG. 19B The retainer 302' is shown in its natural, unbiased state. Typically, the retainer 302' is configured to allow the frame 30 to be inserted into a rough opening (RO) of the structure (not shown) along a first insertion direction D1, and to prevent the frame 30 from being pulled out of the opening along a second pull-out direction D2.

[0299] like FIG. 19B As shown, the retainer 302' includes a seat 310' fixed to the frame 30, a flexible arm 312' extending from the seat 310', a stop arm 314' extending from the flexible arm 312', and an engagement feature 316' extending from the flexible arm 312' and / or the stop arm 314'. FIG. 20B and FIG. 21B As shown, in various embodiments, the retainer 302' is operable such that during insertion of the frame 30 along the first insertion direction D1, the flexural arm 312' bends along a first flexural direction, and as the frame 30 moves along the second pull-out direction D2, the flexural arm 312' bends along a second flexural direction. FIG. 18B As shown, the retainer 302' may optionally include a strap member 302a' extending rearward from the seat portion 310'.

[0300] like FIG. 18B As shown, the strap member 302a' may optionally include a plurality of fastener holes for receiving one or more fasteners (e.g., screws or nails). The strap member 302a' is generally flexible between a retracted configuration and an extended configuration, in which the strap member 302a' extends toward the center of the window unit 10, and in the extended configuration, the strap member 302a' extends upward away from the center of the window unit 10.

[0301] like FIG. 19BAs shown, the seat 310' includes a bottom section 310a' and a return section 310b'. The flexural arm 312' includes a sliding section 312a', an extension section 312b', a rod section 312c', and a rear section 312d'. The stop arm 314' also terminates at a bent end 314a'. Furthermore, the engagement feature 316' includes an engagement edge 316a' ( FIG. 18B The engagement edge 316a' includes one or more sharp edges or teeth for biting or rubbing against the head H of the rough opening (RO) frame. FIG. 20B In other words, engagement feature 316' includes one or more teeth configured to bite into the material defining the rough opening (RO) as the frame moves in an inward direction (e.g., D2).

[0302] As shown, the return segment 310b' extends rearward over a portion of the bottom segment 310a'. The rod segment 312c' extends from the return segment 310b' (as shown, located at the middle of the seat portion 310'). The rear segment 312d' extends downward from the rod segment 312c', and the sliding segment 312a' extends upward from the rear segment 312d' and beyond the engagement feature 316'. The stop arm 314' extends rearward from the engagement feature 316' and / or the extension segment 312b' toward the bottom segment 310a' (in an outward or rearward direction). In some embodiments, the retainer 302' is configured to be fixed in a constrained state (downward compression) such that the retainer 302' is flattened against the frame 30. The retainer 302' can be held in the constrained state using a fixing member (e.g., tape). The fixing member can be removed to release the retainer 302' into an extended state, such that the retainer 302' protrudes outward from the frame 30, as... FIG. 1 As shown.

[0303] FIG. 20B This is a schematic diagram showing the engagement of retainer 302' with the head H of the rough opening (RO) frame. (See diagram) FIG. 20B As shown, the window opening unit 10 is configured such that it slides along the external direction or the first insertion direction D1 and is inserted from the inside of the rough opening RO. The retaining member 302', specifically the flexible arm 312' and the stop arm 314', serves as a spring body that compresses in height when the engagement edge 316a' of the engagement structure 316' bites into the head H. FIG. 20BAs shown, during compression, the peak at the intersection of the extension segment 312b' and the stop arm moves downward, as does the peak at the intersection of the rod segment 312c' and the sliding segment 312a'. The rod segment 312c' rotates forward and downward, while the sliding segment 312a' and the stop arm 314' slide outward (e.g., against the seat 310'). This compression and sliding action allows the retainer 302' and therefore the window opening unit 10 to be inserted in the external direction or the first insertion direction D1 with a first relatively low insertion resistance. In various embodiments, the engagement edge 316a does not bite or otherwise prevent the sliding of the engagement edge 316a as it slides past the head H. This may be due to the angle of the engagement edge 316a.

[0304] FIG. 21B The diagram illustrates how the retainer 302' deforms and resists movement as the window unit 10 and the retainer 302' move in the inward direction or the second pull-out direction D2. As shown, the lever segment 312c' rotates rearward or springs upward when the engagement edge 316a' of the engagement feature 316' bites into the head H and prevents the engagement feature 316' from sliding relative to the head H. In some examples, the stop arm 314' deflects (e.g., bends) due to the movement of the lever segment 312c', further increasing the resistance to further movement in the inward direction or the second pull-out direction D2. In other words, after the flexural arm 312' bends in the second flexural direction, the stop arm 314' is operable to engage with the seat 310' to inhibit further flexural bending of the flexural arm 312'.

[0305] When the window opening unit 10 is inserted into the rough opening (RO), the retainer 302' compresses and engages (e.g., bites) into the head H of the rough opening (RO), and applies a downward force to the window opening unit 10. The retainer 302' may function to help stabilize the window opening unit 10 in the rough opening (RO) to help ensure that the window opening unit 10 does not fall back inward (i.e., resist pull-out along the second pull-out direction D2). This self-holding or stabilizing feature helps allow a single installer (not shown) to complete leveling and centering tasks without holding the window opening unit 10 in the rough opening (RO). If present, the window sill gasket system 200 ( Figures 12 to 17C This can also help achieve this self-holding / stabilizing function. As shown, the retainer 302' is compressible, thus allowing adjustment and adaptation to a range of typical gap dimensions between the head 32 and the head H of the rough opening (RO). Furthermore, the retainer 302' has lateral flexibility and is made of a spring-like material, which allows for left-right adjustment and leveling of the window unit 10 within the rough opening (RO) without significantly hindering these processes.

[0306] Although in many examples one or more retainers 302, 302' are secured to one or more portions of the window opening unit 10 (e.g., frame 30), in other examples, retainers 302, 302' of similar design are optionally secured to the frame around the rough opening (RO) and engage with the window opening unit 10 when the window opening unit 10 is positioned in the rough opening (RO).

[0307] Weather sealing system

[0308] like Figure 1 As shown, another aspect of this disclosure is a weather sealing system 400, which can be remotely applied (e.g., at a manufacturing site) and used as an external waterproof barrier. The weather sealing system 400 can be offset to an deployed state, or may otherwise be described as a "pop-up" wing. In various examples, the weather sealing system 400 is initially in a retracted or flat configuration ( Figure 4 The frame 30 is provided (e.g., shipped or transported to the installation site) and abuts against the window opening unit 10. This flat or retracted position can be described as a “180° position.” As described below, the weather sealing system 400 can be held in the retracted position using a retaining assembly. After the window opening unit 10 is installed and anchored (e.g., using one or more fasteners, such as screws or nails), the original installer (not shown) or another installer can independently proceed to the outside of the rough opening (RO) to remove the retaining assembly and convert the weather sealing system 400 to the unfolded state. In some examples, upon removal of the retaining assembly, the weather sealing system 400 automatically pops out or protrudes outward from the frame 30 (e.g., at approximately 90°) to rest against the outer surface of the wall forming the rough opening (RO). As described below, the weather sealing system 400 may include a three-dimensional corner seal (e.g., factory-applied and welded, bonded, or otherwise attached) that engages with a head pop-out wing to provide protection against water penetration.

[0309] In many examples, no fasteners (e.g., screws or nails) are used on the outside of the window unit 10 (e.g., the window unit 10 is secured entirely from the inside of the rough opening (RO)). Waterproof tape or other treatments can be applied to the perimeter of the window unit 10, to the weather sealing system 400, to seal the window unit 10 to the outer surface of the wall forming the rough opening (RO). In many examples, the outer surface of the wall may include a weather protection barrier (e.g., Tyvek® Home Packaging supplied by DuPont de Nemours, Inc.).

[0310] Figure 1An internal view of the weather sealing system 400 is shown. As shown, the fixed weather sealing system 400 includes a wing assembly 410 that, when unrestrained, offsets outward to project radially outward from the perimeter of the frame 30. Figure 4 A window unit 10 with various mounting features in a retracted configuration is shown. For example... Figure 4 As shown, the weather sealing system 400 also includes a retaining assembly 412 that releasably secures the wing assembly 410 in a constrained state, such that the wing assembly 410 is compressed toward the frame 30 in a retracted configuration.

[0311] like Figure 3 As shown, the wing assembly 410 includes a plurality of wings 420, including a head wing 420a (also referred to as a top wing 420a), a first side pillar wing 420b, a second side pillar wing 420c, and a windowsill wing 420d. Figure 3 As shown, the wing assembly 410 may optionally include a first corner bridge seal 430 and a second corner bridge seal 432. Optionally, a third corner bridge seal may be located between the first side pillar wing 420b and the window sill wing 420d, and a fourth corner bridge seal may be located between the second side pillar wing 420c and the window sill wing 420d.

[0312] Figure 22 It is an end view. Figure 23A This is an isometric view of one of a plurality of wings 420 (each wing may have substantially similar construction and different lengths corresponding to portions of the frame 30 to which they are attached). As shown, each of the plurality of wings 420 has a connecting portion 440 and a protruding portion 442, with a hinge portion 446 between the connecting portion 440 and the protruding portion 442. The connecting portion 440 is connected to the outer periphery P of the frame 30. Figure 1 The protruding portion 442 is offset by the hinge portion 446 to project radially outward from the outer periphery P of the frame 30 via the hinge portion 446. In some embodiments, the connecting portion 440 may be attached to the frame 30 via adhesion. However, other attachment methods are also contemplated, including any previously described methods. In some embodiments, the hinge portion 446 is formed of a first material, and the protruding portion 442 is formed of a second material different from the first material. The first material of the hinge portion 446 may be a first polymer material, and the second material may be a second polymer material different from the first polymer material. Typically, the first material may be softer than the second polymer material (e.g., the first material is inherently elastic, and the second material is typically less elastic or non-elastic). In terms of manufacturing, the connecting portion 440, the protruding portion 442, and the hinge portion 446 may be co-extruded or co-molded components.

[0313] In some embodiments, although a variety of materials may be envisioned, the first material is a nitrile thermoplastic elastomer (TPE), such as the material sold by Aurora Plastics under the trade name Auroraflex™. In some embodiments, although a variety of materials may be envisioned, the second material is glass or mineral-filled polypropylene, or a thermoplastic polyolefin, such as the material sold by Ravago Manufacturing Americas under the trade name RAVATUF® 400X.

[0314] As shown in the figure, the connecting portion 440 includes an elongated, relatively flat, thin rectangular seat 450 and an attachment feature 452 extending from the seat 450 (e.g., vertically). The attachment feature 452 is configured to insert into a complementary feature (e.g., an attachment channel or kerf) of the frame 30 to secure the wing 420 to the frame 30. The attachment feature 452 may be a barbed protrusion that is flexible and allows the attachment feature 452 to be inserted into the complementary feature of the frame 30 but prevents removal therefrom. The attachment feature 452 may be described as a "Christmas tree" construction and may be formed of a first material and a second material, wherein the second material forms the base or trunk of the attachment feature 452 and the first material forms flexible branches of the attachment feature 452.

[0315] The protrusion 442 also includes an elongated, relatively flat, and thin body 458. As shown, the protrusion 442 may have virtually no holes or openings suitable for receiving fasteners (such as nails or screws) to attach the protrusion 442 to the rough opening (RO) of the building or the frame of the wall where the window unit 10 is to be installed. In many examples, the protrusion 442 does not need to include such a feature, since the multiple wings 420 do not provide substantial structural support but are primarily designed to provide an external waterproof barrier function.

[0316] The hinge portion 446 is located between the connecting portion 440 and the protruding portion 442, and is connected to both the connecting portion 440 and the protruding portion 442. The hinge portion 446 is configured to flex between a folded state and an extended state. In the folded state, the protruding portion 442 folds and abuts against the connecting portion 440; in the extended state, the protruding portion 442 extends away from the connecting portion 440 at an angle between the connecting portion 440 and the protruding portion 442. Figure 22 and Figure 23AAs shown (e.g., 90 degrees, or greater than 90 degrees, such as 100 degrees). The hinge portion 446 has a width that is selected to allow the protrusion portion 442 and the connecting portion to not only displace at an angle relative to each other, but also to displace laterally to both small and large lateral offsets.

[0317] For example, by projecting a small portion of the hinge portion 446 vertically at a 90-degree position, the edges of the connecting portion 440 and the protruding portion 442 define a relatively small lateral offset between them (in the interior / exterior direction during installation). Furthermore, by extending a larger portion of the width of the hinge portion 446 laterally (in the interior / exterior direction during installation), the edges of the connecting portion 440 and the protruding portion 442 have a greater lateral offset between them. In this way, the hinge portion 446 provides the function of the wing 420 to accommodate changes in wall thickness when the window unit 10 is installed in the rough opening (RO). In some embodiments, the hinge portion 446 is at least 1 / 8 inch, 1 / 4 inch, 3 / 8 inch, or 1 / 2 inch wide to facilitate sufficient depth adaptation relative to the wing 420.

[0318] Figure 23B Another design change applicable to one, some, or all of wing 420 is shown, as illustrated in wing 420'. As shown in the figure, with... Figure 23A Compared to the design, Figure 23B The seat portion 440' in the design is slightly narrower. Furthermore, the protrusion 442' includes multiple recesses 442a' that form in the outer surface of the early protrusion 442' (i.e., the surface protruding from the building surface that the protrusion 442' ultimately abuts). These recesses 442a' have a thickness and protrude from the back side of the protrusion 442' to help create a gap or spacing, also known as a spacer, between a particular wing 420' and the surface that the wing 420' ultimately abuts. Figure 23B This design is typically applied to the wing 420 corresponding to the windowsill 38 of the window unit 10. This helps ensure that outside air, or more specifically, outside air pressure, can pass under the windowsill 38 to reach the air / water barrier between the windowsill 38 and the rough opening (RO). However, the separator does not interfere with the drainage capacity of the wing 420', helping to ensure a waterproof installation. As shown, recesses 442a' are staggered along the length of the wing 420'. Each recess 442a' is shown as having a circular, dome-shaped profile, but various shapes are envisioned (e.g., cross-shaped, square, rhomboid, or other patterns and shapes and combinations thereof). The recesses 442a' can be cold-formed, molded, or otherwise incorporated into the wing 420'.

[0319] In addition, such as Figure 23BAs shown, the wing 420' optionally includes an edge seal 450a', which is made of a more flexible or softer material (e.g., an elastomer) and is configured to help ensure that water does not penetrate between the wing 420' and the frame 30 of the window unit 10. The edge seal 450a' typically extends along the length of the seat portion 450'.

[0320] Figure 24 It shows Figure 1 A close-up view of the first corner of the frame 30, which is defined at the intersection of the head 32 and the first side post 34 of the frame 30 (the frame 30 also defines a second corner at the intersection of the head 32 and the second side post 36 of the frame 30). As shown, a first corner bridge seal 430 is located at the first corner and provides a transition between the head wing 420a and the first side post wing 420b (a second corner bridge seal 432 is similarly located at the second corner and similarly provides a transition between the head wing 420a and the second side post wing 420c).

[0321] Figure 25 These are isometric views of a first corner bridge seal 430 in various embodiments, with a second corner bridge seal 432 substantially similar to the first corner bridge seal 430. As shown, the first corner bridge seal 430 includes an eaves groove 460 in the form of an L-shaped flange formed by two flat material plates and a cover 462 in the form of a flat material plate extending from the eaves groove 460 in an orthogonal plane. The first corner bridge seal 430 may be made of a substantially flexible material (e.g., an elastomeric material) such that it can be folded similarly to a wing 420. For example, the cover 462 and / or the eaves groove 460 may both be substantially flexible (e.g., elastomeric) and capable of elastic deformation.

[0322] Figure 26A first corner bridge seal 430 and a second corner bridge seal 432 assembled to a head wing 420a are shown. As shown, the cornice 460 of the first corner bridge seal 430 is connected to the connecting portion 440 and the hinge portion 446 of the head wing 420a. In some examples, the cover 462 is also fixed to the protrusion 442 of the head wing 420a. The second corner bridge seal 432 is optionally fixed to the head wing 420a at the end opposite to the first corner bridge seal 430. At least in this way, water flowing onto the head wing 420a will be guided along the first side pillar wing 420b and the second side pillar wing 420c to the first corner bridge seal 430 and the second corner bridge seal 432, respectively. Along these lines, the first corner bridge seal 430 is optionally fixed to the first side pillar wing 420b. For example, the cover 462 is optionally fixed to the protrusion of the first side pillar wing 420b. Optionally, the cornice 460 can be fixed to the connecting portion of the first side pillar 420b. The second corner bridge seal 432 can be similarly fixed to the second side pillar 420c.

[0323] Figure 27 It shows Figure 1 A close-up view of the first corner of the frame 30 shows that a complementary edge feature 470 (e.g., an attachment channel or kerf) extends around the outer periphery P of the frame 30 and forms into the outer edge of the frame 30. As previously described, the connecting portions of the plurality of wings 420 are connected to (inserted into) the complementary edge feature 470 to secure the plurality of wings 420 around the outer periphery P of the frame 30.

[0324] Figure 28 This is a close-up view of the first corner, showing the head wing 420a and the first side pillar wing 420b fixed to the complementary edge feature 470. Figure 27 The first corner bridge seal 430 is not shown in the document. Figure 29A This is a close-up view of the third triangular portion of frame 30, which is defined at the intersection of the windowsill 38 and the first side post 30 of frame 30 (e.g., as shown in the image). Figure 1 (As shown). Similarly, the fourth corner of frame 30 is defined at the intersection of window sill 38 and the second side post 30 of frame 30. As shown, in some designs, the first side post wing 420b and window sill wing 420d overlap but are not fixed together or to them by corner bridge seals. The second side post wing 420c and window sill wing 420d can be arranged and configured similarly relative to each other at the fourth corner as described above. However, Figure 29B Another embodiment is shown in which the first side pillar wing 420b and the window sill wing 420d are secured together using a corner bridge seal 430a, similar to the corner bridge seal 430. If necessary, the second side pillar wing 420c may optionally be secured to the window sill wing 420d using another corner bridge seal.

[0325] In short, such as Figure 3 As shown, the wing assembly 410 includes: a head wing 420a fixed or connected to the head 32 of the frame 30; a first side post wing 420b connected or fixed to the first side post 34 of the frame; a second side post wing 420c connected to the second side post 36 of the frame; and a windowsill wing 420d connected to the windowsill 38 of the frame 30. Furthermore, as... Figure 3 As shown, the first corner bridge seal 430 overlaps with the first side wing 420b and the top wing 420a, and the second corner bridge seal 432 overlaps with the second side wing 420c and the top wing 420a to define a continuous waterproof barrier extending around the outer perimeter P of the frame 30 along the first side post 34, the head 32, and the second side post 36. Conversely, the first side post wing 420b and the second side post wing 420c overlap with the windowsill wing 420d.

[0326] Figure 30 The window unit 10 in its retracted configuration is shown, wherein multiple wings 420 ( Figure 3 The wings fold outwards, and the retaining assembly 412 holds the multiple wings in the retracted configuration. According to some embodiments, the retaining assembly 412 includes multiple retaining clips 480, such as head clip 480a, first side post clip 480b, second side post clip 480c, and windowsill clip 480d. Figure 31 The diagram shows the window opening unit 10 removed to allow the multiple wings 420 to unfold and transform into a retaining assembly 412 after conversion into an active or mounted configuration. While retaining clips 480 are optionally employed, in other embodiments, adhesives (e.g., tape or coatings) may be additionally or alternatively used to temporarily secure the multiple wings 420 to the folded configuration. For example, a pressure-sensitive adhesive kit may be applied. In this example, the adhesive can be removed from the multiple wings 420 without damaging them. As another alternative, cardboard, paper, or other materials in a “C” or “F” shape may be used instead of one or more retaining clips 480.

[0327] Figure 32 This is a close-up view of the first corner section, which has a head wing 420a and a first side pillar wing 420b, as well as a first corner bridge seal 432 folded into a stowed configuration. As shown, the first corner bridge seal 432 can be folded onto itself so that the first corner bridge seal 432 does not protrude or extend from the outer periphery P of the frame 30.

[0328] Figure 33AThis is a partial view of the length of a retaining clip 480 according to the first design, wherein each retaining clip 480 (e.g., head clip 480a, first side post clip 480b, second side post clip 480c and windowsill clip 480d) may have a substantially similar design (except for having a length suitable for retaining each of the respective plurality of wings 420 in a retracted configuration). Figure 34A yes Figure 33A The image shows a cross-sectional view of the retaining clip 480. (See image.) Figure 34A As shown, retaining clip 480 includes a first channel insert 482, a first retaining lip 486, and a second retaining lip 488. As illustrated, the first channel insert 482 is substantially parallel to and interconnects with the first retaining lip 486 (e.g., defining a "C" shape in cross-section). Retaining clip 480 may extend approximately the length of the portion of the frame 30 for which it is mounted (e.g., head 32, first side post 34, second side post 36, and windowsill 38). Alternatively, the length of each retaining clip 480 may be broken down into one or more smaller, individual clamping elements, rather than a single long clamping element.

[0329] The retaining clips 480 are elastically deformable, allowing them to be attached to the frame 30, for example, in a friction-fit manner. In some embodiments, the retaining clips 480 are formed of a polymeric material, such as polyvinyl chloride (PVC). The channel insert 482 may include barbs, forks, or protrusions to facilitate mechanical engagement with complementary surface features (e.g., auxiliary channels or kerfs) formed in the frame 30. The retaining lip 486 may include rounded bends or hooked ends to facilitate positive biasing of portions of the frame 30. A second retaining lip 488 may extend or protrude substantially vertically relative to the channel insert 482 and the first retaining lip 486. The retaining lip 486 extends substantially parallel to the channel insert 482, and the first retaining lip 486 and the channel insert 482 define a receiving channel 489 therebetween. The second retaining lip 488 may optionally serve as an insertion stop extending substantially perpendicular to the first retaining lip 486 and the first channel insert 482, and may optionally be configured to abut against the back (or outside) of the frame 30 when the retaining clips 480 are assembled to the frame 30.

[0330] For example, Figure 35A This is a sectional view at the head 32 of frame 30, showing the cross-sectional view according to... Figure 33AA retaining clip 480, namely a head retaining clip 480a, is designed to releasably engage with a complementary surface feature 490 (e.g., an attachment channel or saw kerf) formed in the back face 44 or outer face 44 of the frame 30 toward the outer periphery P and specifically in the head 32. For reference, the complementary surface feature 490 may optionally be formed in each of the head 32, the first side post 34, the second side post 36, and the windowsill 38 of the frame 30. As shown, a first channel insert 482 is releasably engaged in the complementary surface feature 490, wherein a second channel insert 484 is arranged along and engages with the outer face 44. Conversely, a first retaining lip 486 extends over the head wing 420a and specifically across the protrusion 442 to retain the protrusion 442 folded and abutting against the connecting portion 440. A second retaining lip 488 extends along the back face 44. Typically, the first retaining lip 486 extends along the side of the frame 30, and the wing 420 of the wing assembly 412 is received between the retaining lip 486 and the side or outer periphery P of the frame 30.

[0331] Each retaining clip 480 can be similarly secured around the frame 30 to hold the plurality of wings 420 in a retracted configuration. In other words, the channel inserts of retaining clips 484, 484 are releasably secured to complementary features 490 (e.g., attachment channels) of the frame 30, and retaining lips 486, 488 are received on the wing assembly 410 to releasably secure the wings 420 in a constrained state or a retracted configuration.

[0332] Each retainer 480 is reusable, allowing it to be removed from and reinstalled on the frame 30 without damage. The retainer 480 can also be installed and removed without damaging the multiple wings 420 or the corner bridge seals 430, 432. The retainer 480 can be removed and reinstalled manually without the use of special tools.

[0333] Figure 33B This is a partial view of the length of a retaining clip 480' shown in another design according to some embodiments, wherein each retaining clip 480' (e.g., head clip 480a', first side post clip 480b', second side post clip 480c', and windowsill clip 480d') may be substantially similar to each other (except having a length suitable for holding each of the respective plurality of wings 420 in a retracted configuration). Figure 34B yes Figure 33B The image shows a cross-sectional view of the retaining clip at 480'. Figure 34BAs shown, retaining clip 480' includes a first channel insert 482', a second channel insert 484', a first retaining lip 486', and a second retaining lip 488'. As shown, the first channel insert 482' and the second channel insert 484' are substantially orthogonal, and the first retaining lip 486' and the second retaining lip 488' are similarly orthogonally offset. Retaining clip 480' may extend approximately the length of the frame 30 portion (head 32, first side post 34, second side post 36, and windowsill 38) for which it is mounted. Alternatively, the length of each retaining clip 480' may be broken down into one or more smaller individual clamping elements, rather than a single long clamping element.

[0334] The retaining clips 480' are elastically deformable, allowing them to be attached to the frame 30, for example, in a friction-fit manner. In some embodiments, the retaining clips 480' are formed of a polymeric material, such as polyvinyl chloride (PVC). The channel inserts 482', 484' may include barbs, forks, or protrusions to facilitate mechanical engagement with complementary surface features (e.g., attachment channels or kerfs) formed in the frame 30. The retaining lips 486', 488' may include rounded, flexed, or hooked ends to facilitate positive biasing of portions of the frame 30. The first retaining lip 486' extends substantially parallel to the first channel insert 482', defining a receiving channel 489' therebetween. The second retaining lip 488' optionally serves as an insertion stop extending substantially perpendicular to the first retaining lip 486' and the first channel insert 482', and is optionally configured to abut against the back of the frame 30 when the retaining clips 480' are assembled to the frame 30.

[0335] For example, Figure 35B This is a cross-sectional view at the head 32 of frame 30, showing a retaining clip 480', or head retaining clip 480a', which releasably engages with a complementary surface feature 490' (e.g., an auxiliary channel or saw kerf) formed toward the outer periphery P in the back surface 44 or outer surface 44 of frame 30 and specifically in the head 32. For reference, complementary surface features 490' may optionally be formed in each of the head 32, the first side post 34, the second side post 36, and the windowsill 38 of frame 30. As shown, a first channel insert 482' releasably engages in the complementary surface feature 490', with a second channel insert 484' arranged along and engaging the outer surface 44. Conversely, a first retaining lip 486' extends across the head wing 420a and specifically across the protrusion 442 to retain the protrusion 442 folded and abutting against the connecting portion 440. A second retaining lip 488' extends along the back surface 44. Typically, the first retaining lip 486' extends along the side of the frame 30, and the wing 420 of the wing assembly 412 is received between the retaining lip 486' and the side or outer periphery P of the frame 30.

[0336] Each retaining clip 480' can be similarly secured around the frame 30 to hold the plurality of wings 420 in a retracted configuration. In other words, the channel inserts of retaining clips 482', 484' are releasably secured to complementary features 490' (e.g., attachment channels) of the frame 30, and retaining lips 486', 488' are received above the wing assembly 410 to releasably secure the wings 420 in a constrained state or a retracted configuration.

[0337] Adjustment system

[0338] Figure 36A The first side column 34 according to the first design is shown. Figure 1 A close-up view of a portion of the adjustment system 500 fixed to the first side post 34, and particularly of the edge adjuster 502a among multiple edge adjusters. The adjustment system 500 can be used to help straighten the side posts 34, 35 to help create a more uniform external appearance between the window sash and the frame 30. In various examples, by performing this function, the adjustment system 500 helps to improve the weather sealing capability of the window unit 10, for example by creating more weather strip contact between the window sash and the frame 30.

[0339] Multiple edge adjusters can be substantially similar to the first edge adjuster 502a fixed to the first side post 34. Figure 36A For example, the second edge adjuster 502b can be fixed to the second side post 36 of the frame 30 (e.g., in...). Figure 2 (The location of the edge adjuster 502b indicated in the text). It is conceivable that any number of edge adjusters 502 can be placed at any number of locations in the frame 30. Figure 37A A close-up isometric view of the first edge adjuster 502a removed from frame 30 is shown to reveal more details. Figure 38A and Figure 39A They are Figure 36A Front and side views of the edge adjuster 502a.

[0340] As shown, the first edge 502a includes a guide 504, a first ramp 506, and a second ramp 508. The first edge adjuster 502a defines a longitudinal axis extending between the first ramp 506 and the second ramp 508. The guide 504 is located between the first ramp 506 and the second ramp 508 and includes a sliding surface 504a, a first guide edge 504b, and a second guide edge 504c. The sliding surface 504a is recessed (e.g., relative to the first ramp 506 and the second ramp 508) to define the first guide edge 504b and the second guide edge 504c. The first guide edge 504b and the second guide edge 504c are optionally spaced apart by a distance (e.g., 1.5 inches) corresponding to the width of a standard wood, composite, or polymer filler sheet. As shown, the guide 504 may optionally include a fastener hole 505 (e.g., for a screw or bolt). Fastener holes 505 can be used to secure frame 30 to rough opening (RO) and / or secure first edge adjuster 502a to frame 30 (e.g., side post 34 or 36) using fasteners. Additionally or alternatively, one or more edge adjusters 502 can be coupled or secured to frame 30 via adhesive.

[0341] The thicknesses of both the first ramp portion 506 and the second ramp portion 508 gradually decrease, changing from a first, larger thickness to a second, smaller thickness in the direction away from the guide portion 504. In use, the first edge adjuster 502a is assembled into the first side post 34, with its longitudinal axis extending along the first side post 34. Once the window opening unit 10 receives the rough opening (RO), the stencil (not shown) slides upward or downward above the first ramp portion 506 or the second ramp portion 508, respectively, until the stencil enters the guide portion 504. In some examples, the user (not shown) feels a tactile response as the stencil slides into the guide portion 504 and into place. At this time, the stencil can be driven into the gap between the first edge adjuster 502a and the first side post of the rough opening (RO). This stenciling action helps to reinforce the first side post 34 of the window opening unit 10. Any number of edge adjusters (e.g., a design similar to the first edge adjuster 502a) can be attached to the perimeter P of the frame 30 (e.g., at a location far from the installation site) for example, on the first side post 34 and the second side post 36.

[0342] Figure 36B Another close-up view is shown of a first side post 34 and a portion of an adjustment system 500' fixed to the first side post 34, according to another design shown as an edge adjuster 502', particularly of a plurality of edge adjusters 502. The plurality of edge adjusters 502' includes a first edge adjuster 502a' fixed to the first side post 34. Figure 36B) and the second edge adjuster 502b' fixed to the second side post 36 of the frame 30 (similar to Figure 2 (502b). Multiple edge adjusters 502' are optionally substantially similar. Figure 37B It shows Figure 36B A close-up view shows the first adjustment hole 510a' among a plurality of adjustment holes included in the frame 30, with the first edge adjuster 502a' removed. As shown, the first adjustment hole 510a' is formed in the first side post 34. Although not shown, the second side post 36 includes a similar adjustment hole (not shown) in which a second edge adjuster 502'b can be secured. Any number of edge adjusters 502' and corresponding adjustment holes 510' can be included.

[0343] Figure 38B This is a first isometric view in edge adjuster 502'. Figure 39B This is a second isometric view of the edge adjuster 502'. As shown, the edge adjuster 502' includes a contact head 511' having a plurality of engagement features 512' and an adjustment body 520' extending from the contact head 511', the adjustment body 520' being configured to receive in an adjustment hole 510' in the frame 30 (e.g., in a first adjustment hole 510'). The adjustment body 520' is rotatably actuated to adjust the depth of the adjustment body 520' within the adjustment hole 510'. The contact head defines a protrusion distance projecting from the frame 30 based on the depth of the adjustment body 520' within the adjustment hole 510'.

[0344] In some embodiments, the adjusting body 520' of the edge adjuster 502' may have external threads, and the adjusting hole 510' may have complementary internal threads. In this way, the adjusting body 520' can be rotatably adjusted (e.g., screwed in or unscrewed) to adjust the distance by which the contact head 511' protrudes from the frame 30. For example, the plurality of engagement features 512' of the contact head 511' may include a plurality of radial protrusions 530' with a plurality of grooves 532' between the protrusions. In some examples, the grooves may be sized to engage with one end (e.g., the tip) of a standard flathead screwdriver (e.g., with a 1 / 4-inch head and at least 4-inch shaft length). The contact head 511' may have a terminal or free end defining a dome-shaped leading profile.

[0345] As shown in the figure, the contact head 511' may include a circumferential groove 534' ( Figure 39B A thin filament (e.g., strand or braid) may be wound around the contact head 511' and coiled in the circumferential groove 534'. To extend the contact head 511', the thin filament (not shown) may be pulled to rotate the contact head 511', and the adjusting body 520' may be unscrewed to extend the contact head 511'.

[0346] In several examples, the first edge adjuster 502a' is positioned closer to the rear or outer side 44 of the window opening unit 10 than to the front 42. In this way, an installer (not shown) can insert a screwdriver or other tool into the gap between the window opening unit 10 and the frame of the rough opening (RO), engage the tool with the edge adjusters 502, 502', use the tool to rotate the edge adjuster 502', and engage the edge adjuster 502' (particularly the contact head 511') with the frame of the rough opening (RO). In other examples, the installer can pull on a thin filament (not shown) wound around the contact head 511' and coiled in the circumferential groove 534' to adjust the depth of the first edge adjuster 502' or the amount by which the contact head 511' extends from the frame 30.

[0347] Method of installation

[0348] The window unit 10 can be installed according to the various concepts described in the preceding chapters. Specifically, the installation of the window unit 10 in the rough opening (RO) can be performed from the inside of the rough opening (RO) and can be carried out by a single installer from the inside of the rough opening.

[0349] As part of the installation process, a rough opening (RO) should be prepared in the building structure to install the window unit 10. Typically, the rough opening (RO) is 1 / 2 inch to 3 / 4 inch larger than the window unit 10 in both width and height, but other configurations are also possible. Some methods also include forming the rough opening (RO), such as by cutting out the rough opening (e.g., covering the rough opening frame with plywood cladding). The sill portion of the frame of the rough opening (RO) (lower frame) can be waterproofed (e.g., using appropriate waterproof tape).

[0350] Then, the window unit 10 is partially extended from the retracted configuration to the active configuration. Specifically, by removing the connecting shelf 112 from the support shelf 110, the anchor clip 102 (or anchor clip 102') is converted to the mounting configuration, rotated 180 degrees so that it no longer extends inward to the center of the window unit 10, and then the connecting shelf 112 is reinserted into the support shelf 110 such that the connecting shelf protrudes radially outward from the outer periphery P of the frame 30. When the connecting shelf 112 is fully inserted into the support shelf 110, the claw 150 engages with the slot 174. In various examples, this engagement produces an audible "click" or noise, providing the installer with a clear, audible cues indicating that the connecting shelf 112 has been accurately secured and is at the desired insertion depth. This audible cues can be enhanced by adjusting the spring offset and material selection of the anchor clip 102. The "click" or vibration can also occur as tactile feedback, indicating to the user that the connecting shelf 112 has been accurately installed. Various details regarding the insertion depth and assembly of the connecting shelf 112 have been provided in the preceding chapters.

[0351] Advantageously, in all implementations, the aforementioned steps do not require any tools. In other words, the removal, reversal, re-insertion, and engagement / assembly of the anchor clip 102 can all be performed manually. If it is desired to remove the connecting shelf 112 from the support shelf 110 after the claw 150 engages with the slot 174, the user can lift the claw 150 from the slot 174 (e.g., by hand and / or using a tool such as a screwdriver as described above), and then pull out the connecting shelf 112.

[0352] For example, a single installer inserts or pushes the window unit 10 into the rough opening (RO) from the inside. The window unit 10 can be passed through the rough opening (RO) from the outside and then repositioned or pushed or pulled outwards to take position, but this is generally not preferred. The ability and functionality of installation from the inside of the unit is an important feature of the window unit 10, as conventional window installation requires at least one installer to be located on the outside of the rough opening (RO) and / or at least one installer to be located on the inside of the rough opening (RO).

[0353] In some embodiments, when inserting the window unit 10 into the rough opening (RO), the bottom of the window unit 10 is first inserted into the rough opening (RO), and then the window unit 10 is tilted rearward to the outside of the rough opening (RO), such that the retaining system applies a retaining force to the window unit 10 to maintain a positive engagement between the window unit 10 and the frame of the rough opening (RO). The mounting stabilization system 300 allows the window unit 10 to be inserted into the rough opening (RO) in a first inside-out direction with a first insertion force, and prevents the window unit from being pulled out of the opening in a second outside-in direction with a second pull-out force, the second pull-out force being significantly greater than the first insertion force. The method includes inserting the window unit 10 into the rough opening (RO) in a first direction with a force that meets or exceeds the insertion force. The retainer 302 of the mounting stabilizer system 300 can engage with the head H of the frame of the rough opening (RO), thereby generating noise to provide a clear, audible cue to the installer that the retainer 302 has been properly engaged. In some embodiments, the retainer 302 and the anchor clip 102 together provide an audible cue to the installer indicating that the window unit 10 has been engaged within the frame of the rough opening (RO) and is accurately positioned within the rough opening (RO).

[0354] The window opening unit 10 is pushed into the rough opening (RO) until the anchor clip 102 engages with the edge of the rough opening (RO), specifically with the side post portion of the rough opening frame. A retaining system applies a retaining force to the window opening unit 10 to maintain accurate engagement between the window opening unit 10 and the frame of the rough opening (RO) when the window opening unit 10 is inserted into the rough opening (RO). The retaining system eliminates the need for fasteners to apply this retaining force to secure the window opening unit 10 to the rough opening frame. The anchor clip 102 serves as a engagement system that engages positively with the inner surface of the rough opening frame from the inside of the rough opening (RO), and the retaining system is operated to maintain positive engagement between the engagement system and the rough opening frame (RO) when inserted into the rough opening frame (RO).

[0355] For example, as previously described, when the window opening unit 10 rests on the sill portion of the rough opening frame and the mounting stabilizer system 300 engages with the head H of the rough opening frame, the sill pad system 200 provides an offset tilt bias toward the outside of the rough opening (RO), as previously described. While there is some resistance when inserting the window opening unit 10 into the rough opening (RO) as the stabilizer system 300 automatically engages with the head H, this resistance can be easily overcome by a single installer, and the resistance to pulling the window opening unit 10 out of the rough opening (RO) is significantly greater, preventing accidental removal or falling of the window opening unit 10 from the rough opening (RO).

[0356] If necessary, the strap member 302a' of the retainer 302' (or a similar feature of the retainer 302) can be reoriented (e.g., flexed) to protrude upwards away from the window unit 10 and abut against the head H of the rough opening frame. The strap member 302a' can then be fastened (e.g., using screws or nails) to the rough opening frame to further ensure that the window unit 10 is securely held in place.

[0357] Next, the window unit 10 is centered in the rough opening (RO). In some embodiments, due to the thickness of the sill shim 202, the window unit 10 is initially spaced a desired distance from the sill portion of the rough opening frame. In some embodiments, this distance is approximately 1 / 4 inch. The window unit 10 can be centered left and right by inserting a screwdriver with a standard tip (e.g., a 1 / 4-inch thick tip) and turning the screwdriver to ensure the desired minimum clearance is achieved at the first side post 34 and the second side post 36. To begin the caulking / leveling process, a level is used to check the levelness of the window unit 10, and a single caulking shim is slid under the lower side post shim 202 to begin leveling the window unit 10. Additional caulking shims are used as needed to achieve the desired level and sill spacing, and the level height at the sill 38 is measured periodically as needed.

[0358] Once the desired level and spacing are achieved at the sill portion of the window opening unit 10, fasteners (e.g., screws or nails) pass through the first anchoring clip 102a and the second anchoring clip 102b (corresponding to the two bottommost clamps in the window opening unit 10) and enter the rough opening frame.

[0359] Then, the window unit 10 can be vertically and squared, and fully connected to the frame of the rough opening (RO). For example, the user can vertically position one of the first side post 34 and the second side post 36 to a vertical level. Tools (e.g., pry bars or levers) can be used to adjust the verticality of the first side post 34 and / or the second side post 36 to adjust the verticality of the side posts 34, 36. Additionally or alternatively, the installer can use an airbag designed for this purpose, which can be inflated to adjust the gap between the side posts 34, 36 and the rough opening frame, thereby adjusting its vertical level, or other suitable methods can be implemented as needed. Once adjusted to a vertical level, the remaining anchor clips 102 are secured to the rough opening frame until all anchor clips 102 are attached to the rough opening frame using one or more fasteners, thus structurally securing the window unit 10 to the rough opening (RO).

[0360] In some embodiments, the installer adjusts the adjustment system 500 to engage the rough opening (RO) in the frame (side post portion). The deployment or adjustment of the adjustment system 500 can be performed to help ensure that any torsional forces applied to the frame 30 (e.g., during strong winds such as hurricanes) do not cause the frame 30 to twist or deform to a point of failure. In many examples, the adjustment system 500 is adjusted from the outside of the window opening unit 10 using edge adjusters 502, 502' (e.g., to fill or otherwise engage the rough opening (RO)). Because the edge adjusters 502, 502' can be positioned and biased towards the outside of the window opening unit 10, access and adjustment can be conveniently made from the outside. Although, by design, external installation of the sprue and / or access to the contact head 511' can be conveniently made via external methods, in many embodiments, the installer can access the window opening unit 10 from either side (inside and / or outside).

[0361] Installers can apply an air sealant (e.g., sprayed foam or other air-sealing material) around the outer perimeter P of the window unit 10 within the gap between the rough opening (RO) frame and the window unit 10 to form an internal air seal. This internal air seal can be continuous and substantially or completely uninterrupted. An internal air seal is typically required to ensure proper water management. As previously mentioned, the positioning of the window sill gasket system 200 helps to provide sufficient clearance for the air sealant to deposit within the gap and also provides a continuous clearance at the perimeter of the window unit 10 to ensure a continuous seal. This sealing operation is typically performed from the inside of the rough opening (RO). It should be noted that the sealant can be applied before or after the steps of the external waterproofing barrier described below in conjunction with the weather sealing system 400.

[0362] Compared to other methods and systems, at this point, the window unit 10 is completely adjusted from the inside of the rough opening (RO) into a square, vertical, and securely fixed position within it. This can be completed by one installer, without the need for two. At this point, or at a later time as needed, the same installer or another installer can proceed to the outside of the rough opening (RO) to complete the installation of the external waterproof barrier for the window unit 10 within the rough opening (RO). This contrasts with the traditional nail-wing installation method, which requires a second installer on the outside of the rough opening (RO) during the installation of the window unit 10.

[0363] Forming an external waterproof barrier for mounting unit 10 includes removing retaining clip 480, causing the plurality of wings 420 to change from a retracted configuration to a radially outward-protruding mounting or deployable configuration. In various operations, to ensure accurate deployment of the plurality of wings 420 (or wings 420'), the sill retaining clip 480d is removed first, followed by the first side frame retaining clip 480b and the second side frame retaining clip 480b, and finally the head retaining clip 480a. This sequence helps ensure accurate overlap of the plurality of wings with the first corner bridge seal 430 and the second corner bridge seal 432, wherein the sill wing 420d overlaps outward with the first side pillar wing 420b and the second side pillar wing 420c.

[0364] Typically, multiple wings 420 do not use fasteners, in contrast to conventional studded wings. While such fasteners (e.g., screws or nails) are absent in many examples, it is conceivable that such fasteners could be implemented in other embodiments (e.g., Figure 23B (Example). Regardless, installation is performed by waterproofing the first side wing 420b, the second side wing 420c, and then the head wing 420a using waterproof tape or other suitable waterproofing material. Typically, a weather-sealing barrier (e.g., Tyvek® Home Packaging supplied by DuPont de Nemours, Inc.) will be present on the exterior wall of the building and will be cut twice at a 45-degree angle at the rough-opening head corner and folded vertically inward. Once the first side wing 420b, the second side wing 420c, and the head wing 420a have been waterproofed, the weather-sealing barrier can be folded down over the head wing 420a, and a waterproofing material (e.g., waterproof tape) can be applied at the 45-degree cut at the corner. In many examples, no waterproofing material (e.g., waterproof tape) is applied to the sill wing 420d. The absence of a seal at the sill 38 of the frame 30 helps ensure that the sill wing 420d functions as a waterproof barrier, rather than an air seal at the sill 38. This water-based, rather than air-based, barrier structure promotes pressure equalization with the external air pressure at the location below the windowsill 38 and at the exterior of the rough opening sealant. This pressure equalization helps prevent water from being forced through the water seal at the windowsill 38 during storms or other events with high external atmospheric pressure.

[0365] Various advantages can be achieved based on the exemplary systems and methods described above. Examples may include one or more of the following: greater efficiency (e.g., a 50% or greater reduction in cycle time); easier to learn; easier to remember; easier to train; potentially lower physical demands (e.g., the window unit 10 is not installed from the outside, which may be located on uneven ground or require a ladder); no falling outwards during the installation of the window unit 10; installation can be performed by one person from inside the building structure; internal and external installation tasks do not need to be completed simultaneously; improved installation quality and performance of the window unit 10 after installation; an industry-unique installation method that brings numerous benefits to installers; faster cycle time; improved performance (water and air penetration); adaptation to changes in wall depth; simplified sleeve installation for finishing carpenters; separation of internal and external work so that they can be completed "independently".

It will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments without departing from the scope of this disclosure. Therefore, the embodiments are intended to cover modifications and variations of the invention, provided they fall within the scope of the appended claims and their equivalents.
