Description

[0001] Cross-reference of related applications

[0002] This application claims the benefit and priority of U.S. Application No. 63 / 528,233, filed July 21, 2023, and U.S. Application No. 63 / 639,086, filed April 26, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to safety barrier systems, and more specifically to safety barrier systems that involve mesh and / or other fillers reinforced in a frame. Background Technology

[0004] Security barrier systems can be used on doors and windows. These systems typically involve securing mesh or other filler material within a frame using certain fasteners. The inherent challenge of security barriers revolves around securing, fixing, or fastening the mesh or other filler material to the door or window frame using a fastening system that is both strong and secure enough to meet or exceed current standards. Current fasteners typically involve variations of screws, rivets, wedges, tape, glue, or combinations thereof to secure the filler material within the frame.

[0005] However, a common problem with these safety barrier systems is that their manufacture is both time-consuming and labor-intensive. They typically require a large portion of the assembly process to be manually constructed, which increases both manufacturing time and cost. Therefore, there is a need for safety barrier systems using fasteners that allow the safety barriers to be manufactured and assembled through automated or at least semi-automated processes. There is also a need for safety barrier systems that are cheaper, faster, and easier to assemble than current systems.

[0006] Therefore, a safety barrier system that meets at least two objectives is desired. First, it should provide a secure fixing arrangement that meets or exceeds current standards. Second, it preferably uses fasteners capable of manufacturing and assembling the safety barrier through automated or semi-automated processes. In other words, it is desirable to develop a safety system that meets or exceeds current standards, in which manufacturing and assembly can be performed through automated or semi-automated processes to reduce the labor-intensive nature of assembly.

Detailed Implementation

[0008] This disclosure applies to security barrier systems for doors and windows of buildings, including residential buildings. Such applications may be referenced for ease of illustration. However, it should be understood that this disclosure also has other applications, such as fencing and railing systems, insect screens for doors and windows, barriers for covering openings and vents, walls or partitions for structures, or any other application where meshing or separation is desired.

[0009] The following description should not be considered limiting, but is only used for the purpose of describing the general principles of exemplary embodiments. Throughout this specification, references to “a form,” “an embodiment,” “an embodiment,” “some embodiments,” “implementation,” “some implementations,” “some applications,” or similar language mean that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of this disclosure. Therefore, the appearance of the phrases “in one embodiment,” “in an embodiment,” “in some embodiments,” “in some implementations,” and similar language throughout this specification does not all refer to the same embodiment.

[0010] The terms “top” and “bottom”, “upper” and “lower”, and “vertical” and “horizontal” as used herein are for illustrative purposes only and are not intended to limit the description of the embodiments, as referenced items may be interchanged in position and orientation. Furthermore, as used herein, the terms “substantially” and / or “about” mean that the specified dimensions or parameters may vary within acceptable manufacturing tolerances for a given application.

[0011] Figure 1A safety barrier system 10 is shown, comprising a rectangular frame 12 (or window frame) consisting of a plurality of frame assemblies 14 (four in this case). Frame assemblies 14 define an opening occupied by a mesh / filled barrier 16. The rectangular frame extends around and supports the mesh / filled barrier 16. The mesh / filled barrier 16 can be made of any of a variety of filler materials, such as stainless steel wire, perforated metal sheet, insect-proof fabric, etc. Frame assemblies 14 are typically aluminum channels with various internal structures. The edges of the mesh / filled barrier 16 are fastened within the frame assemblies 14, which in turn connect to each other at the corners of the frame 12. Details of various embodiments of frames, frame assemblies, mesh / filled barriers, and other aspects of safety barrier systems are described, for example, in U.S. Patent Nos. 6,802,357 and 8,191,606, the entire contents of which are incorporated herein by reference.

[0012] At a high level, this disclosure generally relates to various fastening assemblies for retaining and maintaining mesh (or filler) in a safety barrier. Each fastening system typically includes an outer window frame, an inner window frame, and a spacer that houses the mesh / filler. It is generally envisioned that the inner window frame and spacer can be inserted into the outer window frame using automated or semi-automated processes and machinery (e.g., modified or improved presses). As further described below, the wing-shaped elements (or leg-shaped elements) of the inner window frame and the wing-shaped elements (or lips) of the spacer are designed to be pushed / inserted into place by machine to increase the strength of each frame assembly. The use of fasteners, such as support screws or rivets, also significantly enhances the tensile strength of the filler material and better secures it to the outer window frame. Furthermore, it should be understood that the terms "mesh" and "filler" are used extensively in this disclosure. The term "filler" is intended to broadly refer to any kind of sheet or other material that can be used in the systems and methods described herein.

[0013] Figure 2A , Figure 2B , Figure 2C and Figure 2D A first embodiment of the frame assembly 100 is shown, which generally illustrates a serrated lock with a push-button concept. Figure 2AA frame assembly 100 in an assembled state is shown. In one form, the frame assembly 100 includes an outer window frame 112 comprising two opposing sidewalls 102 that are generally parallel to each other. Each sidewall 102 preferably has a base 104 and a top 106 separated by a partition wall 108, and the top 106 may have a narrower width than the base 104. The base 104 preferably includes one or more corner fixing screws 110 for attaching one frame assembly 100 to another at a corner of the frame 10. In this form, the top 106 is preferably U-shaped and defines a channel 113 or recess opening toward the interior of the safety barrier system 10.

[0014] Figure 2B The outer window frame 112 before assembly is shown. In one form, the outer window frame 112 may be made of aluminum, although other materials may also be used. As can be seen in the figure, in this form, the U-shaped top 106 includes two sets of serrated teeth 114. Each set is located on the interior of the sidewalls 102 and faces each other. In this form, there are multiple (in this case four) closely spaced serrations 114 (or barbs or teeth) near the middle of each sidewall 102. The outer window frame 112 also preferably includes additional teeth 116 or serrations / barbs on the interior of each sidewall 102 near the upper end of the top 106. The serrations 114 and 116 are generally used to hold the inner window frame 120 in the channel 113, as further described below. In this form, the two sidewalls 102 of the outer window frame 112 narrow at their upper ends and terminate in two thin walls 118, preferably thinner than the rest of the sidewalls 102, to receive plugs, as discussed below.

[0015] Figure 2C The inner window frame 120 before assembly is shown. The inner window frame 120 is generally configured to be inserted into, received within, and held by the outer window frame 112. The inner window frame 120 is preferably in the form of a flexible U-shaped member having two serrated leg-shaped members 122 (or wing-shaped members). The inner window frame 120 may be made of aluminum, although other materials may also be used. As can be seen in the figure, the serrations are located on the outer sides of the two leg-shaped members 122. A set of closely spaced serrations 124 is preferably configured to engage corresponding closely spaced serrations 114 on the outer window frame 112 in order to hold the inner window frame 120 in the passage 113. The inner window frame 120 preferably includes additional teeth 126 or serrations configured to engage with additional teeth 116 on the outer window frame 112. In this form, the two leg-shaped members 122 widen at their upper ends and terminate in two wide walls 127, preferably as wide as or wider than the rest of the leg-shaped members 122. These two wide walls 127 (in combination with the spacer) act as plugs to facilitate the insertion of the inner window frame / spacer assembly into the outer window frame 112 during assembly.

[0016] Figure 2D The spacer 128 before assembly is shown. The spacer 128 is generally configured to insert and be received within a channel 129 (or recess) formed by two leg-shaped members 122 of the inner window frame 120. The spacer 128 preferably includes two lip portions 130 (or wing-shaped members) terminating in the cover 132. The spacer 128 may be made of Santoprene, although other thermoplastic elastomers or other materials may also be used. The lips 130 are configured to fold (or clamp or compress) around the mesh and / or other filler 138 to engage the mesh and / or other filler 138 and allow it to be received within the spacer 128. During assembly, the lower side of the cover 132 preferably engages the upper end of the outer window frame 112. Figure 2A As can be seen, the mesh and / or other filler 138 is preferably secured in place within the spacer 128 by fasteners 136 (such as support screws or rivets), which are inserted approximately at or directly above the top of the closely spaced serrations.

[0017] In some cases, it has been found that serrations are desirable as a primary engagement feature between the outer window frame 112 and the inner window frame 120. Multiple serrations provide a robust engagement between the outer window frame 112 and the inner window frame 120 to retain the inner window frame 120 within the outer window frame 112. These serrations and other engagement features (such as hooks) of the outer window frame are described throughout this disclosure. These engagement features of the outer window frame generally engage with corresponding engagement features (such as corresponding serrations and hooks) of the inner window frame. Furthermore, in some cases, it has been found that a plug formed by the combination of the inner window frame 120 and the spacer 128 is desirable to facilitate the mechanical application of a pushing or pulling force for inserting the inner window frame / spacer combination into the outer window frame 112.

[0018] Furthermore, as mentioned above, in one form, an elastomeric material or other non-metallic material is preferably used for the spacer 128. In some forms, the mesh and / or other filler 138 may be made of a strong metallic material such as stainless steel, and the outer window frame 112 and the inner window frame 120 may be made of a relatively lightweight metallic material such as aluminum. It is desirable to have a spacer 128 between the metallic mesh and / or other filler 138 and the metallic inner window frame 120 to separate and isolate these components from each other. Otherwise, direct contact of certain metallic materials, such as stainless steel and aluminum, can promote galvanic corrosion. When stainless steel and aluminum are used together in an assembly, electrons from aluminum tend to transfer to the stainless steel over time, leading to the weakening of the aluminum. This weakening causes aluminum deterioration and results in a shortened component lifespan.

[0019] Figure 3A , Figure 3B , Figure 3C and Figure 3DA second embodiment of the frame assembly 200 is shown, which generally illustrates a serrated lock concept (without a plug). Figure 3A The frame assembly 200 in an assembled state is shown. This second embodiment is generally similar to the first embodiment, but there are some structural differences in the outer and inner window frames, as described below.

[0020] In one form, the frame assembly 200 includes an outer window frame 212 comprising two opposing sidewalls 202 that are generally parallel to each other. Each sidewall 202 preferably has a base 204 and a top 206 separated by a partition wall 208, and the top 206 may have a narrower width than the base 204. The base 204 preferably includes one or more corner fixing screws 210 for attaching one frame assembly 200 to another at a corner of the frame 10. In this form, the top 206 is preferably U-shaped and defines a channel 213 or recess opening toward the interior of the safety barrier system 10.

[0021] Figure 3B The outer window frame 212 before assembly is shown. In one form, similar to the first embodiment, the outer window frame 212 can be made of aluminum, although other materials may also be used. As can be seen in the figure, in this form, the U-shaped top 206 includes two sets of serrated teeth 214. Each set is located on the interior of the sidewalls 202 and faces each other. In this form, there are multiple (in this case four) closely spaced serrations 214 (or barbs or teeth) near the middle of each sidewall 202. The outer window frame 212 also preferably includes additional teeth 216 or serrations / barbs on the interior of each sidewall 202 near the upper end of the top 206. The serrations 214 and 216 are generally used to hold the inner window frame 220 in the channel 213, as further described below. In this form, contrary to the first embodiment, the two sidewalls 202 of the outer window frame 212 do not terminate in two thin walls at the upper end. Instead, they terminate in additional teeth 216 on each sidewall 202.

[0022] Figure 3CThe inner window frame 220 before assembly is shown. The inner window frame 220 is generally configured to be inserted into, received within, and held by the outer window frame 212. The inner window frame 220 is preferably in the form of a flexible U-shaped member having two serrated leg-shaped members 222 (or wing-shaped members). In one form, similar to the first embodiment, the inner window frame 220 may be made of aluminum, although other materials may also be used. As can be seen in the figure, the serrations are located on the outer sides of the two leg-shaped members 222. A set of closely spaced serrations 224 is preferably configured to engage corresponding closely spaced serrations 214 on the outer window frame 212 in order to hold the inner window frame 220 in the channel 213. The inner window frame 220 preferably includes additional teeth 226 or serrations configured to engage with additional teeth 116 on the outer window frame 112. In this form, the two leg-shaped members 222 do not have a widened plug portion at the upper end. Alternatively, they terminate in additional teeth 226 on each leg member 222, which are configured to engage corresponding additional teeth 216 on the outer window frame 212.

[0023] Figure 3D The spacer 228 before assembly is shown. Spacer 228 is preferably similar to spacer 128 used with the first embodiment. Spacer 228 may be made of Santoprene, although other thermoplastic elastomers or other materials may also be used. The spacer 228 is generally configured to be inserted into and received within a channel 229 (or recess) formed by two leg-shaped members 222 of the inner window frame 220. Spacer 228 preferably includes two lip portions 230 (or wing-shaped members) terminating in the cover 232. The lips 230 are configured to fold (or clamp or compress) around the mesh and / or other filler 238 to engage the mesh and / or other filler 238 and allow it to be received within the spacer 228. During assembly, the lower side of the cover 232 preferably engages the upper end of the outer window frame 212. Figure 3A As can be seen, the mesh and / or other filler 238 is preferably secured in place within the spacer 228 by fasteners 236 (such as support screws or rivets), which are inserted approximately at or directly above the closely spaced serrations. In one embodiment, the fasteners 236 are positioned further away from the bottom of the spacer 228 than the fasteners in the first embodiment.

[0024] Figure 4A , Figure 4B , Figure 4C and Figure 4D A third embodiment of the frame assembly 300 is shown, which generally illustrates a hook lock with a push-plug concept. Figure 4A The frame assembly 300 in an assembled state is shown. This third embodiment is generally similar to the first embodiment, but has some structural differences related to the serrations in the outer and inner window frames, as described below.

[0025] In one form, the frame assembly 300 includes an outer window frame 312 comprising two opposing sidewalls 302 that are generally parallel to each other. Each sidewall 302 preferably has a base 304 and a top 306 separated by a partition wall 308, and the top 306 may have a narrower width than the base 304. The base 304 preferably includes one or more corner fixing screws 310 for attaching one frame assembly 300 to another at a corner of the frame 10. In this form, the top 306 is preferably U-shaped and defines a channel 313 or recess opening toward the interior of the safety barrier system 10.

[0026] Figure 4B The outer window frame 312 before assembly is shown. In one form, similar to other embodiments, the outer window frame 312 may be made of aluminum, although other materials may also be used. As can be seen in the figure, in this form, the U-shaped top 306 does not include the closely spaced serrations (or barbs or teeth) present in the previous two embodiments. Instead, in this form, the U-shaped top 306 includes two hooks 314. Each hook 314 is located inside the sidewall 302 and faces each other. The outer window frame 312 also preferably includes additional teeth 316 or serrations / barbs on the interior of each sidewall 302 near the upper end of the top 306. The hooks 314 and additional teeth 316 are generally used to hold the inner window frame 320 in the channel 313, as further described below. In this form, the two sidewalls 302 of the outer window frame 312 narrow at the upper end and terminate in two thin walls 318, i.e., walls that are preferably thinner than the rest of the sidewalls 302, to receive plugs, as discussed below.

[0027] Figure 4C The inner window frame 320 before assembly is shown. The inner window frame 320 is generally configured to be inserted into, received within, and held by the outer window frame 312. The inner window frame 320 is preferably in the form of a flexible U-shaped member having two leg-shaped members 322 (or wing-shaped members). Similar to other embodiments, the inner window frame 320 can be made of aluminum, although other materials may also be used. As can be seen in the figure, each of the two leg-shaped members 322 has a hook 324 on its outer side. The hook 324 is preferably configured to engage a corresponding hook 314 on the outer window frame 312 to hold the inner window frame 320 in the passage 313. The inner window frame 320 preferably includes additional teeth 326 or serrations configured to engage additional teeth 316 on the outer window frame 312. In this form, the two leg-shaped members 322 widen at their upper ends and terminate in two wide walls 327, preferably as wide as or wider than the rest of the leg-shaped members 322. These two wide walls 327 (in combination with the spacer) act as plugs to facilitate the insertion of the inner window frame / spacer assembly into the outer window frame 312 during assembly.

[0028] Figure 4D The isolator 328 before assembly is shown. The isolator 328 is preferably similar to the isolators used in the other two embodiments. The isolator 328 is generally configured to insert into and be received within a channel 329 (or recess) formed by two leg-shaped members 322 of the inner window frame 320. The isolator 328 preferably includes two lip portions 330 (or wing-shaped members) terminating in the cover 332. The lips 330 are configured to fold (or clamp or compress) around the mesh and / or other filler 338 to engage the mesh and / or other filler 338 and allow it to be received within the isolator 328. During assembly, the lower side of the cover 332 preferably engages the upper end of the outer window frame 312. Figure 4A As can be seen, the mesh and / or other filler 338 is preferably secured in place within the spacer 328 by fasteners 336 (such as support screws or rivets), which are inserted approximately between the hook 314 and the additional serrations 316.

[0029] Figure 5A , Figure 5B , Figure 5C and Figure 5D A fourth embodiment of the frame assembly 400 is shown, which generally illustrates the hook-lock concept (without a push plug). Figure 5A The frame assembly 400 in an assembled state is shown. This fourth embodiment is generally similar to the third embodiment, but there are some structural differences in the outer and inner window frames, as described below.

[0030] In one form, the frame assembly 400 includes an outer window frame 412 comprising two opposing sidewalls 402 that are generally parallel to each other. Each sidewall 402 preferably has a base 404 and a top 406 separated by a partition wall 408, and the top 406 may have a narrower width than the base 404. The base 404 preferably includes one or more corner fixing screws 410 for attaching one frame assembly 400 to another at a corner of the frame 10. In this form, the top 406 is preferably U-shaped and defines a channel 413 or recess opening toward the interior of the safety barrier system 10.

[0031] Figure 5BThe outer window frame 412 before assembly is shown. In one form, similar to other embodiments, the outer window frame 412 may be made of aluminum, although other materials may also be used. As can be seen in the figure, in this form, the U-shaped top 406 includes two hooks 414. Each hook 414 is located inside the sidewall 402 and faces each other. The outer window frame 412 also preferably includes additional teeth 416 or serrations / barbs on the interior of each sidewall 402 near the upper end of the top 406. The hooks 414 and additional teeth 416 are generally used to retain the inner window frame 420 in the channel 413, as further described below. Furthermore, contrary to the third embodiment, the top 406 preferably includes a cavity 419 formed in the partition wall 408 (the base plate of the top 406), which is configured to receive a portion of the inner window frame 420, as described below.

[0032] Figure 5C The inner window frame 420 before assembly is shown. The inner window frame 420 is generally configured to be inserted into, received within, and held by the outer window frame 412. The inner window frame 420 is preferably in the form of a flexible U-shaped member having two leg-shaped members 422 (or wing-shaped members). Similar to other embodiments, the inner window frame 420 can be made of aluminum, although other materials may also be used. As can be seen in the figure, each of the two leg-shaped members 422 has a hook 424 on its outer side. The hook 424 is preferably configured to engage a corresponding hook 414 on the outer window frame 412 to hold the inner window frame 420 in the channel 413. The inner window frame 420 preferably includes additional teeth 426 or serrations configured to engage with additional teeth 416 on the outer window frame 412. In this form, the two leg-shaped members 422 do not have a widened plug portion at the upper end. Alternatively, they terminate in additional teeth 426 on each leg member 422, which are configured to engage corresponding additional teeth 416 on the outer window frame 412. Furthermore, in one form, contrary to the third embodiment, the inner window frame 420 includes a protrusion 427 projecting from the bottom of a "U" shape, and this protrusion is configured to be received within a cavity 419 of the outer window frame 412.

[0033] Figure 5DThe isolator 428 before assembly is shown. The isolator 428 is preferably similar to that used in other embodiments. The isolator 428 is generally configured to insert into and be received within a channel 429 (or recess) formed by two leg-shaped members 422 of the inner window frame 420. Similar to other embodiments, the isolator 428 may be constructed of Santoprene, although other thermoplastic elastomers or other materials may also be used. The isolator 428 preferably includes two lip portions 430 (or wing-shaped members) terminating in the cover 432. The lips 430 are configured to fold (or clamp or compress) around the mesh and / or other filler 438 to engage the mesh and / or other filler 438 and allow it to be received within the isolator 428. During assembly, the lower side of the cover 432 preferably engages the upper end of the outer window frame 412. Figure 5A As can be seen, the mesh and / or other filler 438 is preferably secured in place within the spacer 428 by fasteners 436 (such as support screws or rivets), which are inserted approximately between the hook 414 and the additional serrations 416.

[0034] This disclosure also relates to a method of assembling a safety barrier system such as the various embodiments described above, and the discussion of these various embodiments is incorporated herein. Initially, a mesh and / or other filler, an outer window frame, an inner window frame, and a spacer, as described above, may be provided. In one form, the lip (or wing) of the spacer may be folded (or clamped) around the end of the mesh and / or other filler to retain it within the spacer. The spacer may be disposed within the inner window frame, and the combination of the mesh and / or other filler, the spacer, and the inner window frame may be fastened (or secured) together by fasteners.

[0035] In this configuration, the combination of a fastening mesh and / or other filler, spacers, and inner window frame can be inserted into a channel in the outer window frame. A force can be applied to move the fastening mesh and / or other filler, inner window frame, and spacers into the channel in the outer window frame. This force should be sufficient to move the engagement features of the inner window frame past the engagement features of the outer window frame. It is generally envisioned that this force can be applied as some kind of thrust or pull, which can be applied mechanically in an automated manner, for example, by some form of modified or improved press, hydraulic, or pneumatic machinery. Alternatively, the combination of the fastening mesh and / or other filler, spacers, and inner window frame can be inserted into the channel in the outer window frame by sliding the inner window frame laterally into it. While this method can be performed wholly or partially automated, it is also envisioned that in some cases, the assembly method can be performed entirely manually.

[0036] Figure 6A , Figure 6B and Figure 6CA fifth embodiment of the frame assembly 500 is shown, which generally illustrates a plastic inner wedge fixing system. Figure 6A The frame assembly 500 in an assembled state is shown. This fifth embodiment is generally similar to the previous embodiments, but there are some structural differences in the outer and inner window frames, and glue or tape is used as a separator, as described below.

[0037] In one form, the frame assembly 500 includes an outer window frame 512 comprising two opposing sidewalls 502 that are generally parallel to each other. Each sidewall 502 preferably has a base 504 and a top 506 separated by a partition wall 508, and the top 506 may have a narrower width than the base 504. The base 504 preferably includes one or more corner fixing screws 510 for attaching one frame assembly 500 to another at a corner of the frame 10. In this form, the top 506 is preferably U-shaped and defines a channel 513 or recess opening toward the interior of the safety barrier system 10.

[0038] Figure 6B The outer window frame 512 before assembly is shown. In one form, similar to other embodiments, the outer window frame 512 may be made of aluminum, although other materials may also be used. As can be seen in the figure, in this form, the U-shaped top 506 includes two hooks 514. Each hook 514 is located on the interior of the sidewall 502 and faces each other. The outer window frame 512 also preferably includes additional teeth 516 or serrations / barbs on the interior of each sidewall 502 near the upper end of the top 506. The hooks 514 and additional teeth 516 are generally used to hold the inner window frame 520 in the channel 513, as further described below.

[0039] Figure 6C The inner window frame 520 (or plastic inner wedge 520) before assembly is shown. The inner window frame 520 is generally configured to be inserted into, received, and held by the outer window frame 512. The inner window frame 520 is preferably in the form of a flexible U-shaped member having two leg-shaped members 522 (or wing-shaped members). In one form, the inner window frame 520 may be made of a plastic material, such as polyvinyl chloride (PVC), although other materials (such as aluminum) may also be used. As can be seen in the figure, each of the two leg-shaped members 522 has a hook 524 on its outer side. The hook 524 is preferably configured to engage a corresponding hook 514 on the outer window frame 512 in order to hold the inner window frame 520 in the channel 513. The inner window frame 520 preferably includes additional teeth 526 or serrations configured to engage with additional teeth 516 on the outer window frame 512. In this form, each of the two leg-shaped members 522 preferably terminates at its upper end in a widened plug (or stopper) portion 527.

[0040] In this manner, glue or adhesive is applied between the mesh / filler 538 and the inner window frame 520, serving as a separator 528. In one embodiment, the adhesive 528 is envisioned as being in the form of double-sided tape, which is folded and applied to both sides of the edge of the mesh / filler 538. The inner window frame 520 can then be applied to the tape, such that the tape is sandwiched between the mesh / filler 538 and the inner window frame 520. This tape can be in the form of epoxy adhesive, polyurethane adhesive, or other types of tape, and can be used to secure the mesh and the inner window frame 520 together. Furthermore, optionally, as... Figure 7 As shown, the mesh and / or other filler 538 can be further secured in place relative to the inner window frame 520 by fasteners 536 (such as support screws or rivets driven through the inner window frame 520). Although Figure 7 Fastener 536 is shown, but it is usually not visible when the outer window frame 512 is positioned properly above the inner window frame 520.

[0041] Another example of the assembly method is now described, for example, relating to frame assembly 500. However, it should also be understood that the method can be used for other frame assemblies described in this disclosure. Initially, a sheet of mesh / filler 538, after being cut to the desired size, can be arranged in a workspace. Next, spacers 528 (e.g., double-sided tape) can be applied along one edge of the mesh / filler 538, with spacers 528 applied to both sides of the mesh / filler 538. The mesh / filler 538 (with spacers 528) is then inserted into the inner window frame 520. The mesh / filler 538 (with spacers 528) is preferably inserted such that spacers 528 engage with the inner window frame 520 (and do not allow the mesh / filler 538 to directly contact the inner window frame 520). The inner window frame 520 is preferably cut and sized such that it does not cover the corners of the mesh / filler 538. Tools, such as a rubber mallet, can be used to tap the inner window frame 520 and push the combined mesh / filler 538, spacer 528, and inner window frame 520 together. Excess portions of the spacer 528 at the corners of the mesh / filler 538 can be cut and removed.

[0042] In one form, the inner window frame 520 can be riveted, such as by riveting with a riveting machine, so that the mesh / filler 538, the spacer, and the inner window frame 530 are held together by fasteners 536. For example, rivets 536 can be applied, with the first rivet starting 15 mm from the short edge of the inner window frame 520, and subsequent rivets 536 spaced 150 mm apart. It should be understood that other riveting arrangements and spacings can also be used. The above steps are generally repeated until the four inner window frames 520 are fastened around the outer rectangular perimeter of the mesh / filler 538.

[0043] Next, three of the inner window frames 520 can each slide laterally within their respective outer window frames 512. The three outer window frames 512 are fastened together at two corners by one or more corner fixing screws 510, which engage corner posts 540 or other corner fastening components at each corner. Then, the fourth outer window frame 512 can be aligned and positioned such that the corner fixing screws 510 engage with the corner posts 540 at the other two corners. Once positioned, the fourth outer window frame 512 can be fastened around the fourth inner window frame 520 using a tensioning or pressing machine (not by sliding engagement) to apply force and pull (or push) the outer window frame 512 toward the interior of the mesh / filling 538, and onto and cover the fourth inner window frame 520. The corner fixing screws 510 and corner posts 540 can be reinforced by automatic folding or by applying folding force at the four corners.
