Description

Technical Field

[0001] This invention relates to the field of door and window technology, specifically to a high-performance passive aluminum-plastic co-extruded window system with a concealed frame window sash. Background Technology

[0002] The existing green building and passive building markets are thriving, and passive window systems will be widely used in these buildings. Currently, the passive window market offers a wide variety of products, but without exception, they are all developed to meet the high requirements of passive windows. While these new window systems can reduce the overall heat transfer coefficient of the window and meet the requirements of passive windows, they all share a significant problem: a large window cross-sectional width, especially for windows with operable sashes and the stacked dimensions of the sashes. This inevitably leads to an unsatisfactory aesthetic appearance, and it is difficult to minimize the heat transfer coefficient of the window profiles. Therefore, developing a window system that can meet the high requirements of passive windows, especially the extremely high requirements of passive windows in extremely cold regions, while also possessing a simple cross-sectional width and appearance, is a crucial demand in the passive window market. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a high-performance passive aluminum-plastic co-extruded window system with a concealed frame sash.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A high-performance passive aluminum-plastic co-extruded window system with a concealed frame sash includes a window frame, a mullion within the window frame, a fixed sash glass and a window sash respectively between the mullion and the window frame, and an operable sash glass within the window sash. The window frame, mullion, and window sash are all aluminum-plastic co-extruded structures. The window frame includes an aluminum alloy inner liner and a plastic component covering the inner liner. The mullion includes an aluminum alloy inner liner and a plastic component covering the inner liner. The window sash includes an aluminum alloy inner liner and a plastic component covering the inner liner. One side of the plastic component is connected to the plastic component of the window frame or the plastic component of the mullion via a concealed hinge, and the other side has a window opening handle. Multiple first thermal insulation strips are connected between the interior and exterior sides of the mullion aluminum alloy inner lining. Thermal insulation material is filled between the multiple layers of the first thermal insulation strips. A tongue-shaped watertight adhesive strip is connected to the side of the first thermal insulation strip facing the operable sash glass, and a glass thermal insulation pad is connected to the side of the first thermal insulation strip facing the fixed sash glass, abutting against the fixed sash glass. A glass edge protector is connected to the outer periphery of the operable sash glass. Thermal insulation material is also filled between the glass edge protector and the operable sash glass. The glass edge protector and the tongue-shaped watertight adhesive strip are pressed together. An outer dust-tight adhesive strip is provided on the exterior side of the window frame plastic assembly and the mullion plastic assembly facing the operable sash glass. An inner dust-tight adhesive strip is also provided between the interior side of the window frame plastic assembly and the mullion plastic assembly and the window sash plastic assembly.

[0006] This high-performance passive aluminum-plastic co-extruded window system with concealed frame sash improves the structure of the window frame, mullion, and sash, as well as their connection and installation methods. This allows the entire window system to maintain a low heat transfer coefficient while having a simple and aesthetically pleasing appearance. From the outside, only the window frame is exposed, while the window opening mechanism is hidden on the inside.

[0007] The window sash 4 adopts a window hardware system based on concealed opening hinges, which is not only aesthetically pleasing, but also ensures the continuity of the sealing strip on the innermost side of the window because it is hidden in the space between the window frame and the window sash, thus improving the overall sealing performance of the window.

[0008] When the window is opened and closed, the tongue-shaped watertight sealant strip and the glass edge protector strip are pressed against each other, forming a circumferential sealing structure on the contact line and also forming a heat barrier, which is both dustproof and waterproof; the heat insulation material is a filled polyurethane foam heat insulation material, which has a good heat insulation effect.

[0009] When the window sash is closed, this window system forms at least three sealing lines to ensure the overall sealing performance of the window system. These are the first EPDM outer sealing strip (the outer dust-tight strip 13), the second EPDM tongue-shaped molded integrated sealing strip (the tongue-shaped water-tight strip 10), and the third EPDM inner sealing strip (the inner dust-tight strip 14). These lines form water-tight, dust-tight, and air-tight lines across the entire cross-section of the window system, greatly improving the sealing performance of the entire window when closed and ensuring its excellent thermal insulation and sound insulation performance. This allows the window system to meet the requirements of passive windows in extremely cold regions.

[0010] Furthermore, both the aluminum alloy liner of the window frame and the aluminum alloy liner of the mullion include a first aluminum profile frame. The outdoor side of the first aluminum profile frame is provided with a first extension arm extending toward the operable sash glass and / or the fixed sash glass. The indoor side of the first aluminum profile frame is also connected to the first indoor side liner by a plurality of second thermal insulation strips. The first indoor side liner and the first extension arm are also wrapped inside the plastic component of the window frame or the plastic component of the mullion.

[0011] Furthermore, the aluminum alloy liner of the window sash includes a second aluminum profile frame. The side of the second aluminum profile frame closest to the interior is connected to a second interior side liner via several third thermal insulation strips. The second interior side liner is provided with a second extension arm extending toward the window frame or the mullion. The second interior side liner and the second extension arm are also wrapped inside the window sash plastic assembly. The window sash plastic assembly at the second extension arm is connected to the inner dust-tight adhesive strip.

[0012] In some embodiments, the window sash plastic assembly has a first snap-fit ​​groove and a second snap-fit ​​groove at the right-angled wall near the window frame plastic assembly or the mullion plastic assembly; the inner dust-tight sealing strip has an L-shaped strip body, and the two straight walls of the strip body are respectively provided with a first snap-fit ​​protrusion with a cavity and a second snap-fit ​​protrusion, the first snap-fit ​​protrusion snapping into the first snap-fit ​​groove and the second snap-fit ​​protrusion snapping into the second snap-fit ​​groove; the strip body has an L-shaped first free end near the end of the first snap-fit ​​protrusion and an arc-shaped second free end near the end of the second snap-fit ​​protrusion; when the window sash is closed, the first free end and the second free end act on the right-angled wall of the window frame plastic assembly or the mullion plastic assembly respectively, and form a sealing structure.

[0013] Furthermore, in the closed state of the window sash, the second aluminum profile frame is arranged correspondingly to the interior side of the window frame plastic assembly or the mullion plastic assembly, and the window concealed hinge is installed on the second aluminum profile frame and the interior side; the window opening handle is installed on the window sash plastic assembly included in the second extension arm, and the working end of the window opening handle is located on the corresponding side of the second aluminum profile frame and the window frame plastic assembly or the mullion plastic assembly.

[0014] In some embodiments, the window frame plastic assembly, the mullion plastic assembly, and the window sash plastic assembly each include micro-foamed plastic encasing an aluminum alloy liner, and the outer side of the micro-foamed plastic is provided with a plastic hardened skin.

[0015] Furthermore, a structural sealant is provided between the window sash and the operable glass. One side of the glass edge protector is snapped into the aluminum alloy inner lining of the window sash, and the other side is provided with architectural sealant between it and the periphery of the operable glass. The glass edge protector has multiple chambers arranged sequentially from the outdoor side to the indoor side.

[0016] Furthermore, the indoor side portions of the mullion plastic assembly and the window frame plastic assembly are respectively connected to aluminum alloy glass pressure lines, and an inner sealing strip is provided between the aluminum alloy glass pressure lines and the fixed sash glass, while an outer sealing strip is provided between the fixed sash glass and the outdoor side portions of the mullion plastic assembly and the window frame plastic assembly.

[0017] Furthermore, the tongue-shaped watertight adhesive strip has a raised sloping structure on the side facing the glass edge protector, and a sealing and limiting structure is provided on the outer edge; the glass heat insulation pad has several turbulence protrusions on the side facing the fixed sash glass.

[0018] Furthermore, both the operable sash glass and the fixed sash glass are quad-pane, double-cavity vacuum low-E glass, with two layers of glass on the indoor side.

[0019] Compared with existing technologies, the beneficial effects of this invention are: 1. This high-performance passive aluminum-plastic co-extruded window system with a concealed frame sash improves the structure of the window frame, mullion, and sash, as well as their connection and installation methods, so that the entire window system has a simple and beautiful appearance while ensuring a low heat transfer coefficient; 2. The window frame, mullion, and sash all adopt an aluminum-plastic co-extruded structure, so that the entire window system has both the advantages of metal windows and the advantages of partially plastic windows, with excellent sound insulation, heat insulation, and thermal insulation performance; 3. The sash adopts a window hardware system mainly based on concealed opening hinges, which is not only beautiful, but also... 4. The tongue-shaped watertight sealant strip and the glass edge protector strip are pressed together to form a circumferential sealing structure on the contact line, and also to form a heat barrier, which is both dustproof and waterproof; 5. When the window sash is closed, this window system can form at least three sealing lines to ensure the sealing performance of the entire window system. It can form a watertight line, a dusttight line and an airtight line on the entire cross-section of the window system, which greatly improves the sealing performance of the entire window in the closed state and ensures its excellent heat insulation and sound insulation performance.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figures 1-6As shown, a high-performance passive aluminum-plastic co-extruded window system with a concealed frame sash includes a window frame 1, a mullion 2 within the window frame 1, a fixed sash glass 3 and a window sash 4 respectively between the mullion 2 and the window frame 1, and an operable sash glass 5 within the window sash 4; the window frame 1, the mullion 2, and the window sash 4 are all aluminum-plastic co-extruded structures; the window frame 1 includes an aluminum alloy inner liner 101 and a plastic component 102 covering the aluminum alloy inner liner 101. The mullion 2 includes a mullion aluminum alloy inner liner 201 and a mullion plastic component 202 covering the mullion aluminum alloy inner liner 201. The window sash 4 includes a window sash aluminum alloy inner liner 401 and a window sash plastic component 402 covering the window sash aluminum alloy inner liner 401. One side of the window sash plastic component 402 is connected to the window frame plastic component 102 or the mullion plastic component 202 via a window concealed hinge 6, and the other side is provided with a window opening handle 7. The window frame aluminum alloy inner liner... Multiple first thermal insulation strips 8 are connected between the interior and exterior of the 101 and the mullion aluminum alloy liner 201, respectively. Thermal insulation material 9 is filled between the multiple first thermal insulation strips 8. A tongue-shaped watertight adhesive strip 10 is connected to the side of the first thermal insulation strip 8 facing the operable sash glass 5. A glass thermal insulation pad 11 is connected to the side of the first thermal insulation strip 8 facing the fixed sash glass 3 and abuts against the fixed sash glass on that side. A glass edge protector strip 12 is connected to the outer periphery of the operable sash glass 5. Thermal insulation material 9 is also filled between the glass edge protector strip 12 and the operable sash glass 5. The glass edge protector strip 12 and the tongue-shaped watertight adhesive strip 10 are pressed together. An outer dust-tight adhesive strip 13 is provided on the exterior side of the window frame plastic assembly 102 and the mullion plastic assembly 202 facing the operable sash glass 5. An inner dust-tight adhesive strip 14 is also provided between the interior side of the window frame plastic assembly 102 and the mullion plastic assembly 202 and the window sash plastic assembly 402.

[0030] This high-performance passive aluminum-plastic co-extruded window system with concealed frame sash improves the structure of the window frame 1, mullion 2, and sash 4, as well as their connection and installation methods. This allows the entire window system to maintain a low heat transfer coefficient while having a simple and aesthetically pleasing appearance. From the outside, only the window frame is exposed, while the window opening mechanism is hidden on the inside.

[0031] The window frame 1, the mullion 2, and the window sash 4 all adopt an aluminum-plastic co-extruded structure, which makes the entire window system have the advantages of both metal windows and partial plastic windows, with excellent sound insulation, heat insulation, and thermal insulation performance.

[0032] The window sash 4 adopts a window hardware system based on concealed opening hinges, which is not only aesthetically pleasing, but also ensures the continuity of the innermost sealing strip (such as the inner dust-tight sealing strip 14) because it is hidden in the space between the window frame and the window sash, thereby improving the sealing performance of the entire window.

[0033] When the window sash 4 is closed, the tongue-shaped watertight adhesive strip 10 and the glass edge protector strip 12 are pressed against each other, forming a circumferential sealing structure on the contact line and also forming a heat barrier, which is both dustproof and waterproof; the heat insulation material 9 is a filled polyurethane foam heat insulation material, which has a good heat insulation effect.

[0034] By setting the first thermal insulation strip 8 on the left and right sides (non-indoor and outer sides) of the aluminum alloy lining 101 of the window frame and the aluminum alloy lining 201 of the mullion, a sealed cavity can be formed between the aluminum alloy lining and the inner and outer sides, and the thermal insulation material 9 can be filled in, so that it can provide thermal insulation in all directions, reduce the direct contact and heat transfer between the inner and outer sides of the aluminum alloy lining, and improve the basic thermal insulation capacity of the entire window system.

[0035] When the window sash 4 is closed, this window system can form at least three sealing lines to ensure the sealing performance of the entire window system. These are the first EPDM outer sealing strip (the outer dust-tight strip 13), the second EPDM tongue-shaped molded integrated sealing strip (the tongue-shaped water-tight strip 10), and the third EPDM inner sealing strip (the inner dust-tight strip 14). These can form water-tight lines, dust-tight lines, and air-tight lines across the entire cross-section of the window system, greatly improving the sealing performance of the entire window when closed and ensuring its excellent thermal insulation and sound insulation performance.

[0036] Furthermore, both the aluminum alloy liner 101 of the window frame and the aluminum alloy liner 201 of the mullion include a first aluminum profile frame 24. The outdoor side of the first aluminum profile frame 24 is provided with a first extension arm 25 extending toward the operable sash glass 5 and / or the fixed sash glass 3. The indoor side of the first aluminum profile frame 24 is also connected to a first indoor side liner 27 by a plurality of second thermal insulation strips 26. The first indoor side liner 27 and the first extension arm 25 are also wrapped inside the plastic component of the window frame or the plastic component of the mullion.

[0037] The second thermal insulation strip 26, connected to the first indoor side liner 27, can form two cavities on the indoor side. While appropriately increasing the cross-sectional dimensions of the indoor side, it minimizes the increase in weight, thus providing sufficient space and position on its sides to connect the window concealed hinge. After the first extension arm 25 is wrapped in plastic, it can limit the opening sash glass on the outdoor side and also facilitates the installation of the outer dust-tight sealing strip at the closing point of the opening sash glass.

[0038] Furthermore, the aluminum alloy liner 401 of the window sash includes a second aluminum profile frame 28. The side of the second aluminum profile frame 28 closest to the interior is connected to a second interior side liner 29 by a plurality of third thermal insulation strips 15. The second interior side liner 29 is provided with a second extension arm 30 extending toward the window frame 1 or the mullion 2. The second interior side liner 29 and the second extension arm 30 are also wrapped inside the window sash plastic assembly. The window sash plastic assembly at the second extension arm 30 is connected to the inner dust-tight adhesive strip 14.

[0039] The second aluminum profile frame 28 installed inside the window sash 4 can be used to connect and install the window concealed hinge and the window opening handle, and can also be used to connect and fix the opening sash glass and the glass edge strip. The interior part can also be connected to the second interior side liner 29 through the third thermal insulation strip 15. The second extension arm formed by the second interior side liner can cover the window frame or mullion. The interior dust-tight sealing strip is installed at this location, which can form a better sealing structure at the right angle.

[0040] Furthermore, in combination Figure 5 As shown, the window sash plastic assembly 402 has a first snap-fit ​​groove 31 and a second snap-fit ​​groove 32 at the right-angled wall near the window frame plastic assembly 102 or the mullion plastic assembly 202; the inner dust-tight adhesive strip 14 has an L-shaped adhesive strip body 1401, and the two straight walls of the adhesive strip body 1401 are respectively provided with a first snap-fit ​​protrusion 1402 and a second snap-fit ​​protrusion 1403 with cavities. The first snap-fit ​​protrusion 1402 snaps into the first snap-fit ​​groove 31, and the second snap-fit ​​protrusion 1403... The first locking protrusion 1403 is snapped into the second locking groove 32; the adhesive strip body 1401 has an L-shaped first free end 1404 on the end side near the first locking protrusion 1402 and an arc-shaped second free end 1405 on the end side near the second locking protrusion 1403; when the window sash is closed, the first free end 1404 and the second free end 1405 act on the right-angle wall of the window frame plastic component 102 or the mullion plastic component 202 respectively, and form a sealing structure.

[0041] The above-mentioned arrangement allows for the connection and fixation of the inner dust-tight adhesive strip 14 on both surfaces, resulting in good stability and preventing easy detachment during long-term opening and closing. The arrangement of the first free end 1404 and the second free end 1405 does not hinder the opening and closing of the window sash 4, and can also automatically form a sealing structure on the two right-angled surfaces when the window sash is closed. Compared to forming two layers of seal at the right-angle bend, the sealing effect is better, and the spacing is flexible and deformable, allowing for adaptive sealing.

[0042] In some embodiments, the window sash plastic assembly 402 is further provided with a relief groove 33 near the first snap-fit ​​groove 31, and the adhesive strip body 1401 is further provided with a linear protrusion 1406 corresponding to the relief groove. The linear protrusion 1406 enables the adhesive strip body 1401 to have good deformation ability, and when squeezed, the linear protrusion 1406 can move into the relief groove 33.

[0043] Furthermore, in the closed state of the window sash, the second aluminum profile frame 28 is arranged correspondingly to the interior side of the window frame plastic assembly or the mullion plastic assembly, and the concealed window hinge 6 is installed on the second aluminum profile frame 28 and this side; the window opening handle 7 is installed on the window sash plastic assembly included in the second extension arm 30, and the working end of the window opening handle 7 is located on the corresponding side of the second aluminum profile frame 28 and the window frame plastic assembly or the mullion plastic assembly. This arrangement allows the hinge to be well concealed; in the closed state, the hinge is not visible from either the inside or outside of the window, and the structure is not complicated.

[0044] Furthermore, the window frame plastic assembly 102, the mullion plastic assembly 202 and the window sash plastic assembly 402 each include micro-foamed plastic 19 (polyvinyl chloride) wrapping an aluminum alloy liner, and the outer side of the micro-foamed plastic 19 is provided with a plastic hard skin 20, such as a PVDF coating.

[0045] Furthermore, a structural sealant 16 is provided between the window sash 4 and the operable glass 5. One side of the glass edge protector 12 is snapped into the aluminum alloy inner lining 401 of the window sash, and the other side is provided with architectural sealant 17 between it and the periphery of the operable glass 5. This connection method is both simple and stable. The glass edge protector 12 has multiple chambers arranged sequentially from the outdoor side to the indoor side, and has a certain deformation capacity.

[0046] Furthermore, the indoor side portions of the mullion plastic assembly 202 and the window frame plastic assembly 102 are respectively connected to aluminum alloy glass pressure lines 21, and an inner sealing strip 23 is provided between the aluminum alloy glass pressure lines 21 and the fixed sash glass 3, and an outer sealing strip 22 is provided between the fixed sash glass 3 and the outdoor side portions of the mullion plastic assembly and the window frame plastic assembly.

[0047] The aluminum alloy glass pressure line 21, together with the inner and outer sealing strips and the extension arm, can clamp and fix the glass, and can also form a sealing structure. The heat insulation material 9 can be filled into the aluminum alloy glass pressure line to avoid direct contact between the glass and the metal, thus forming a heat barrier.

[0048] Furthermore, the tongue-shaped watertight adhesive strip 10 has a raised slope structure 1001 on the side facing the glass edge protector strip 12, which can form a sealing line. A sealing limiting structure 1002 is provided on the outer edge, which can limit the glass edge protector strip and seal the outer side. The glass heat insulation pad 11 has several turbulence protrusions on the side facing the fixed sash glass to block the heat exchange between the indoor and outdoor areas.

[0049] Furthermore, both the operable sash glass 5 and the fixed sash glass 3 are quad-pane, double-cavity vacuum low-E glass, with two layers of glass on the indoor side. This type of glass inherently possesses strong heat insulation, heat preservation, and sound insulation and noise reduction capabilities.

[0050] Specifically, this high-performance passive aluminum-plastic co-extruded window system with a concealed frame sash includes the window opening part, the window fixing part, and the window opening hardware part;

[0051] The window opening mechanism mainly consists of an aluminum-plastic co-extruded window frame, an aluminum-plastic co-extruded window sash, and quad-glazed, double-cavity vacuum low-E glass. The aluminum-plastic co-extruded window frame is composed of an aluminum alloy profile liner, nylon PA66 thermal break strips, polyvinyl chloride micro-foam, and a polyvinyl chloride hardened skin (PVDF coating). Polyurethane foam insulation material is filled into the cavities of the thermal break strips to further improve the thermal performance of the window frame. The quad-glazed, double-cavity vacuum low-E glass is bonded to the aluminum alloy profile of the window sash 4 at the manufacturing plant using silicone structural sealant. Nylon PA66 material is also applied around the perimeter of the window sash 4. The glass edge protector 12 is filled with polyurethane foam insulation material between itself and the glass, and silicone building sealant is applied to its outer surface to achieve a seal between the glass and the glass edge protector. The nylon PA66 glass edge protector has a multi-cavity structure and a boss at the front end to form a compression seal with the EPDM tongue-shaped molded integrated sealing strip (the tongue-shaped water-tight strip 10). The tongue-shaped water-tight strip 10 adopts a molding integrated process to ensure the sealing continuity around the sealing strip. Three sealing lines can be formed between the window sash and the window frame to ensure the sealing performance of the entire window system.

[0052] The window fixing part mainly consists of an aluminum-plastic co-extruded window frame, quad-glazed double-cavity vacuum low-E glass, and aluminum alloy glass pressure strips. The aluminum-plastic co-extruded window frame is composed of aluminum alloy profile lining, nylon PA66 thermal insulation strip, polyvinyl chloride micro-foam, and polyvinyl chloride hard skin (PVDF coating). Polyurethane foam thermal insulation material is filled in the cavity of the thermal insulation strip to improve the thermal performance of the window frame. The quad-glazed double-cavity vacuum low-E glass is fixed to the window frame and mullion by aluminum alloy glass pressure strips, EPDM inner glass sealing strips, and EPDM outer glass sealing strips.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
