Description

Technical Field

[0001] This utility model relates to aluminum alloy composite profiles in door and window profile technology, specifically to a nested external screen window profile assembly. Background Technology

[0002] In aluminum alloy inward-opening casement window systems, the installation of screens effectively prevents mosquitoes and other insects from entering. Furthermore, the screens do not obstruct indoor air circulation, allowing fresh air to enter freely while blocking most dust and impurities, ensuring fresh indoor air and a clean environment. This feature not only improves living comfort but also plays a positive role in maintaining indoor hygiene.

[0003] However, there are two main types of screen structures used in inward-opening window systems in the existing technology:

[0004] One of its structural forms is as follows Figure 1 As shown, the screen window is taken into account in the overall system design, and the screen window is completely placed inside the aluminum alloy window frame; however, the drawback of this screen window structure is that the system design requires a sufficiently wide window frame profile; at the same time, the screen window profile is limited by the installation space, and is generally small in size, making it difficult to match various standard casement hardware.

[0005] Another structural form, such as Figure 2 As shown, an additional, completely external screen frame is added to the aluminum alloy window frame and fixed to the exterior side edge of the inward-opening window frame with self-tapping screws. This structure is relatively simple and is usually used for the renovation of old windows, but the connection method has safety hazards. Over time, it is prone to loosening and may fall off. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a nested external screen window profile assembly, which can be used to solve the defects in the above-mentioned technical background.

[0007] The technical problem solved by this utility model is achieved by the following technical solution:

[0008] A nested external screen window profile assembly is used for assembly on the outdoor side of an inward-opening casement window. The assembly includes a screen window frame profile and a screen window sash profile.

[0009] The screen frame profile is a frame profile that matches the corresponding casement window sash. The frame profile is attached to the outer frame of the casement window sash on the inner side, and is assembled and connected to the outer frame of the casement window sash on the attached side through structural fittings to form an integral outer frame structure.

[0010] The screen sash profile is formed within the frame structure of the screen frame profile. A screen mesh is embedded in the screen sash profile to form the screen sash. The screen sash profile is hinged to the screen frame profile on one side via an inward hinge, so that the screen sash can be opened a second time when the casement window is open. The screen frame profile also has an outer limiting frame, which can fit tightly against the edge of the screen sash profile when the screen sash is closed.

[0011] As a further limitation, the structural assembly is one or a combination of snap-fit ​​assembly structure, plug-in assembly structure, and threaded assembly structure, so that the screen window frame profile and the outer frame of the casement window sash can be firmly connected together, thereby improving the stability and safety of the overall structure.

[0012] The screen frame profile has an assembly interface on the side of the casement window sash that is attached to it. The assembly interface includes a nesting groove and a nut groove. The nesting groove and the nut groove are set at an angle. The outer frame of the casement window sash has a matching snap-fit ​​part formed at the position of the nesting groove, and a matching bolt assembly part is reserved at the position of the nut groove.

[0013] As a further limitation, the inward-opening casement window is preferably a single-sash opening structure, and the outer frame is an enclosing structure consisting of the outer window frame of the operable window sash and the mullion profile of the window frame.

[0014] As a further limitation, the screen window sash profile has a pre-reserved adhesive strip groove on the closed side that is in contact with the casement window sash. After the adhesive strip is inserted into the adhesive strip groove, the screen window sash profile can be tightly attached to the surface of the casement window sash profile and press the adhesive strip together, thereby forming a structural seal.

[0015] As a further limitation, the screen frame profile has a rubber strip groove formed on the inner side of the outer limiting frame. After the rubber strip is inserted into the rubber strip groove, the screen sash can form a structural seal by pressing the rubber strip when it is closed.

[0016] As a further limitation, when the screen window sash profile uses an inward hinge to achieve the inward opening function, the maximum opening angle of the entire screen window sash is greater than or equal to 90 degrees.

[0017] As a further limitation, a hardware groove space is reserved between the inner side of the screen window frame profile and the outer side of the screen window sash profile, and the inward opening hinge is installed in the hardware groove space; at the same time, a push handle is also installed in the hardware groove space on the opposite side of the inward opening hinge, and the opening and locking functions of the screen window sash can be realized by operating the push handle.

[0018] As a further limitation, the screen frame profile has a glass railing slot profile assembly structure reserved on the outdoor side, and is assembled with the glass railing slot profile with glass railing through the glass railing slot profile assembly structure.

[0019] Beneficial Effects: This utility model relates to a nested external screen window profile assembly, the design of which ensures a stable assembly between the screen window frame and the inward-opening aluminum alloy window frame. The nested structure between the profiles effectively prevents the risk of the screen window frame falling off, and the use of bolts and nuts further enhances the stability of the connection, thus avoiding any shaking during use. When installing floor-to-ceiling windows, glass railing slots can be inserted on the outdoor side, and tempered laminated glass can be installed to form a robust protective structure.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0026] See Figure 3 , Figure 4 A preferred embodiment of a nested external screen window profile assembly is provided. In this embodiment, the nested external screen window profile assembly is used for assembly on a single-pane inward-opening aluminum alloy casement window to achieve the effect of effectively protecting the window after it is opened by using the screen window panel.

[0027] exist Figure 4 In the illustrated embodiment, the upper part of the window corresponds to the outdoor side, and the lower part corresponds to the indoor side. The corresponding nested external screen window profile assembly is assembled on the outdoor outer side of the frame structure formed by the outer window frame and the window frame mullion profile 15 of the casement window sash 13; and can perform the opening and closing operations of the screen window sash after the casement window sash 13 is opened inward.

[0028] In this embodiment, the screen frame profile 1 uses a combination of nut groove 2 and nested groove 3 as a structural assembly on the side of the mullion profile 15 in the window frame and on the side of the outer window frame of the casement window sash 13. In other embodiments, the structural assembly may also adopt one or a combination of other snap-fit ​​assembly structure, plug-in assembly structure, and threaded assembly structure.

[0029] In this embodiment, a stainless steel nut of matching size is placed in the nut groove 2 as an assembly nut 14. The assembly nut 14 can slide along the length of the profile in the groove of the nut groove 2, but will not rotate or flip. The corresponding mullion profile 15 in the window frame and the outer window frame are formed with plug-in parts that match the nested groove 3 and threaded holes that are opposite to the nut groove 2 and spaced apart. During assembly, the corresponding plug-in parts are inserted into the nested groove 3, and then the position of the assembly nut 14 in the nut groove 2 is adjusted so that it corresponds to the threaded hole. Then, the assembly bolt is installed to complete the assembly of the screen window frame profile 1. At this time, the screen window frame profile 1, the mullion profile 15 in the window frame and the outer window frame form a stable integral structure. The combination of the nut groove 2 / assembly bolt and the nested groove / plug-in part can further improve the reliability of the connection, while avoiding slight shaking caused by the gap between the profiles.

[0030] In this embodiment, the casement window sash 13 is an operable window sash. After assembly on the mullion profile 15 of the window frame, the screen frame profile 1 has grooves for adhesive strips formed on both the inner outer side of the corresponding mullion profile 15 and the inner outer edge of the nested groove 3. By embedding adhesive strips 4 into these grooves, the casement window sash 13 can be opened as shown in the figure. Figure 4 When the window is closed as shown, the corresponding sealing strip 4 can fit tightly against the profile surface of the casement window sash 13 and press the sealing strip together, thereby forming a good structural seal and effectively preventing wind, sand and rainwater from entering the room.

[0031] The assembled screen window frame profile 1 has a rectangular frame structure, and the inner side of the frame facing the indoor side has an assembly area for assembling the screen window sash profile 6.

[0032] The corresponding screen sash profile 6 can be assembled into a rectangular frame structure that matches the assembly area by assembling angle steel plates. At the same time, a cover plate slot is reserved on the screen sash profile 6. The corresponding screen mesh 7 is pressed into the cover plate slot after being tensioned. The surface is flattened and the interior is concealed by the pressure line profile. Finally, the aluminum alloy cover plate profile 9 is used to cover the surface of the pressure line profile to complete the assembly of the screen sash.

[0033] After the screen sash is assembled, a hardware groove space 12 is reserved between the outer contour of the screen sash and the side wall of the assembly area of ​​the screen frame profile 1. The screen frame profile 1 is assembled with the screen frame profile 1 in the hardware groove space 12 area on the opposite side of the vertical edge through a lightweight inward hinge and locking hardware. Through the design of the inward hinge, the screen sash can easily open and close on the screen frame profile 1, and its maximum opening angle should reach or exceed 90 degrees. At the same time, the screen frame profile 1 has an outer limiting frame 11 formed on the outdoor side corresponding to the hardware groove space 12. The outer limiting frame 11 has a reserved rubber strip groove. After the rubber strip 4 is embedded in the rubber strip groove, it can fit tightly with the edge of the screen sash profile 6 when the screen sash 6 is closed, forming a good sealing effect to prevent mosquitoes from entering when the casement window sash 13 is open. In addition, the outer limiting frame 11 also enhances the stability of the screen sash, ensuring the smooth operation of the screen sash during opening and closing.

[0034] In another embodiment, to facilitate the opening of the screen sash, a transmission rod, lock, and other hardware can be installed in the hardware groove space 12 to provide a more convenient operating experience. Simultaneously, the screen sash profile 6 has an inward-curving screen sash profile arm 5 set in the hardware groove space 12, and a push-button handle is installed at the arm 5. The installation of the transmission rod makes opening and closing the screen sash easier; users only need to gently push or pull the transmission rod to achieve smooth opening and closing of the screen sash. The addition of the lock enhances the security and protection of the screen, preventing unauthorized opening when there are pets or children indoors. The push-button handle design is more user-friendly; users do not need to make large movements during operation, but can easily open or close the screen sash with a simple press.

[0035] In addition, for large, floor-to-ceiling windows, to ensure safety, glass railings can be added to the exterior side for protection. The specific implementation method is as follows:

[0036] Before the screen window frame profile 1, insert the glass balustrade slot 10 into the pre-reserved assembly slot on the outer side of the screen window frame profile 1 corresponding to the outer limiting frame 11. The length of the glass balustrade slot 10 is determined according to the actual height of the tempered laminated glass 8 used as the glass balustrade, and the spacing between the relatively set glass balustrade slots 10 is determined according to the actual length of the tempered laminated glass 8 used as the glass balustrade. Install one glass balustrade slot 10 on each of the left and right sides, with the openings of the glass balustrade slots 10 facing each other, and fix them to the screen window frame profile 1 at the bottom of the slots using stainless steel self-tapping screws as shown in the figure to complete the connection. Then, place the tempered laminated glass 8 between the glass balustrade slots 10 on both sides from above, and then fill the gap with weather-resistant sealant.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical content of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
