Description

Technical Field

[0001] This application relates to the field of door and window technology, and more specifically, to an inward tilting sliding window and its window frame exterior profile and screen structure. Background Technology

[0002] Inward-tilting sliding windows are a type of window and door product with both inward-tilting and side-sliding opening methods. Their structure features a triple-seal design, similar to casement windows, resulting in high sealing performance. The glass sash slides inward when fully opened, providing high safety. Because it opens side-sliding, inward-tilting sliding windows do not occupy interior space, making them highly suitable for home renovations and effectively saving interior space. However, because the inward-tilting sliding window sash operates with a track design, its profile structure is stronger and more precise than ordinary casement windows. To ensure a good seal, common screen solutions on the market include externally mounted screens or retractable screens. Both of these are external installations, disrupting the original window and door's integrity and making operation inconvenient for users. Furthermore, the addition of screens reduces the gap between the screen structure and the exterior window frame, allowing rainwater to seep into the room through the gaps, resulting in poor waterproofing. Therefore, the existing mesh structure has the disadvantages of complex structure and poor waterproof sealing performance.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0004] The purpose of this application is to provide an inward tilting sliding window and its exterior window frame profile and screen structure. By installing a screen structure in the exterior window frame profile of the inward tilting sliding window, and setting a sash rubber strip on the mesh profile of the screen structure, which is connected with the frame sealing rubber strip set on the exterior window frame profile to form a first sealing structure, a water accumulation cavity is formed between the mesh profile and the exterior window frame profile, thereby achieving the waterproof sealing performance of the inward tilting sliding window.

[0005] Firstly, this application provides an inward-tilting side-sliding window, the technical solution of which is as follows:

[0006] The inward tilt-and-slide window includes an exterior window frame profile and a mesh structure installed in the exterior window frame profile;

[0007] The exterior profile of the window frame extends with a first limiting part and a second limiting part in the X-axis direction and the Y-axis direction, respectively. A first installation area is formed between the first limiting part and the second limiting part. The first installation area is used to install the screen structure.

[0008] The mesh structure includes a sheet yarn profile. Both ends of the sheet yarn profile along the Y-axis direction are provided with fan-shaped adhesive strips on the X-axis direction near the outside. The end of the second limiting part is provided with a frame sealing adhesive strip on the X-axis direction near the inside. The fan-shaped adhesive strip and the frame sealing adhesive strip are in contact and connected to form a first sealing structure.

[0009] The sheet material has water accumulation cavities at both ends of the window frame exterior profile along the Y-axis.

[0010] This application provides an inward-tilting sliding window. By installing a screen structure within the exterior profile of the window frame, the exterior profile provides necessary support and fixation for the screen structure, ensuring a secure installation. The screen structure, embedded within the exterior profile, reduces the space occupied by the window frame, improving both the practicality and aesthetics of the inward-tilting sliding window. The exterior profile extends with a first limiting part and a second limiting part in the X-axis and Y-axis directions, forming a first installation area between the first and second limiting parts, ensuring the screen can be correctly installed within the exterior profile. The screen structure includes a sheet of mesh, which is made of yarn. The slender strips in the mesh structure are used to connect and fix the screen, preventing mosquitoes and flies from entering the room, and occupying little space. A sash adhesive strip is installed on the exterior side of the mesh profile to fix the screen sash. A frame sealing strip is installed on the interior side of the X-axis of the second limiting part, which abuts against the sash adhesive strip to form a first sealing structure, preventing rainwater from seeping into the exterior window frame profile and improving sealing. At both ends of the mesh profile in the Y-axis direction, water collection cavities are formed with the exterior window frame profile. These cavities can collect rainwater, preventing excessive rainwater from seeping into the room from the exterior window frame profile, thus improving the waterproof performance of the inward-tilting sliding window. Therefore, this inward-tilting sliding window, by connecting the mesh profile to the exterior window frame profile, eliminates the need for an additional screen sash structure, reduces the space occupied by the screen structure, increases the water collection cavity between the screen structure and the exterior window frame profile, effectively controls the drainage of rainwater stored in the cavities, prevents rainwater from seeping into the room, and has excellent waterproof performance.

[0011] Furthermore, the sheet material has a sealing strip on the side closer to the interior in the X-axis direction. The sealing strip is used to abut against the glass sash in the inward tilting sliding window to form a second sealing structure.

[0012] This application provides an inward tilt-and-slide window, in which a stop strip is provided on the side of the screen profile closer to the interior in the X-axis direction. The stop strip is in contact with the glass sash to form a second sealing structure, which can work in conjunction with the first sealing structure to prevent rainwater from seeping into the interior through the screen profile and improve the sealing performance of the inward tilt-and-slide window.

[0013] Furthermore, the gauze profile is provided with a detachable hinge structure in the water accumulation cavity on one side of the Y-axis direction. The hinge structure includes a first movable part and a second movable part that are respectively connected to the exterior profile of the window frame and the gauze profile. The first movable part and the second movable part are hinged to each other at the end near the interior.

[0014] This application provides an inward-tilting sliding window, in which a detachable hinge structure is provided in the water accumulation cavity on one side of the screen profile in the Y-axis direction. The hinge structure allows the screen profile to be easily removed from the exterior profile of the window frame for cleaning and maintenance. The hinge structure includes a first movable part and a second movable part that are respectively connected to the exterior profile of the window frame and the screen profile. The ends of the first movable part and the second movable part near the device are hinged to each other, thereby facilitating the removal of the screen profile from the interior and improving safety.

[0015] Furthermore, the sheet material is provided with a lockable safety lock structure, which is lockably connected to the exterior profile of the window frame.

[0016] This application provides an inward-tilting side-sliding window, which, by setting a lockable safety lock structure on the screen profile, can prevent children from accidentally opening the window in families with children, thus avoiding possible falls.

[0017] Furthermore, the yarn profile is also provided with a magnetic attraction structure.

[0018] Furthermore, the mesh profile has a mesh fan slot with an opening facing the outside. The opening of the mesh fan slot does not protrude beyond the outer edge of the window frame's exterior profile in the X-axis direction. The mesh fan slot is used to install the mesh assembly.

[0019] Furthermore, the mesh assembly includes a mesh, a sheet of yarn for fixing the mesh, and a sheet of yarn adhesive strip and a sheet of yarn pressing line disposed on the side of the sheet of yarn near the outdoors, the sheet of yarn adhesive strip and the sheet of yarn pressing line being used to fix the sheet of yarn.

[0020] Furthermore, the yarn fan slot includes a first slot and a second slot arranged side by side in the X-axis direction. The width of the first slot in the X-axis direction is smaller than the width of the second slot in the X-axis direction, and the length of the first slot in the Y-axis direction is smaller than the length of the second slot in the Y-axis direction. The first slot is used to set the sheet yarn and the yarn mesh, and the second slot is used to set the sheet yarn adhesive strip and the sheet yarn pressing line.

[0021] Secondly, an exterior window frame profile is provided, which is applied to an inward tilt-and-turn window as described in any one of the above claims. The exterior window frame profile extends with a first limiting portion and a second limiting portion in the X-axis direction and the Y-axis direction, respectively. A first installation area is formed between the first limiting portion and the second limiting portion. The first installation area is used to install a screen structure. A frame sealing strip is provided at the end of the second limiting portion on the side closer to the interior in the X-axis direction. The frame sealing strip is used to abut against and connect with the sash sealing strip on the screen structure to form a first sealing structure.

[0022] Thirdly, a mesh structure is provided, which is applied to an inward tilting sliding window as described in any of the above claims. The mesh structure includes a sheet mesh profile, and both ends of the sheet mesh profile along the Y-axis direction are provided with a sash adhesive strip on the side of the X-axis direction closer to the outside. The sash adhesive strip is used to contact and connect with the frame sealing adhesive strip on the exterior profile of the window frame to form a first sealing structure.

[0023] Beneficial Effects: This application proposes an inward-tilting sliding window, its exterior window frame profile, and a screen structure. By installing the screen structure within the exterior window frame profile, the exterior profile provides necessary support and fixation for the screen structure, ensuring a secure installation. The screen structure, embedded within the exterior window frame profile, reduces the occupancy of indoor and outdoor space, improving the practicality and aesthetics of the inward-tilting sliding window. The exterior window frame profile extends with a first limiting part and a second limiting part in the X-axis and Y-axis directions, thereby forming a first installation area for the screen structure between the first and second limiting parts, ensuring correct installation of the screen within the exterior window frame profile. The screen structure includes a sheet of mesh. The profile, specifically the mesh profile, consists of slender strips used to connect and secure the mesh, preventing mosquitoes and flies from entering the room, and occupies minimal space. A sash-mounted adhesive strip is installed on the exterior side of the mesh profile to secure the mesh window sash. A frame sealing strip is installed on the interior side of the X-axis of the second limiting part, which abuts against the sash-mounted adhesive strip to form a first sealing structure, preventing rainwater from seeping into the exterior profile of the window frame and improving sealing. Water accumulation cavities are formed at both ends of the mesh profile along the Y-axis, allowing rainwater to be collected and preventing excessive rainwater from seeping into the room from the exterior profile, thus improving the waterproof performance of the tilt-and-turn sliding window. Therefore, this inward tilting sliding window eliminates the need for an additional screen sash by connecting the screen mesh profile to the exterior window frame profile, reducing the space occupied by the screen mesh structure and increasing the water accumulation cavity between the screen mesh structure and the exterior window frame profile. This effectively controls the drainage of rainwater stored in the water accumulation cavity, preventing rainwater from seeping into the room and providing excellent waterproof performance.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Currently, most screen structures on the market have an additional screen sash. This additional sash reduces the gap between the screen structure and the exterior window frame profile, allowing rainwater to seep into the room through the gaps when it cannot drain away quickly enough, resulting in poor waterproofing. To solve this problem, this application provides an inward-tilting sliding window, its exterior window frame profile, and screen structure.

[0033] Please refer to Figures 1 to 5An inward tilting sliding window and its window frame exterior profile 1 and screen structure 2, the inward tilting sliding window includes a window frame exterior profile 1 and a screen structure 2 installed in the window frame exterior profile 1;

[0034] The exterior profile 1 of the window frame extends with a first limiting part 11 and a second limiting part 12 in the X-axis direction and the Y-axis direction, respectively. A first installation area 13 is formed between the first limiting part 11 and the second limiting part 12. The first installation area 13 is used to install the screen structure 2.

[0035] The mesh structure 2 includes a sheet yarn profile 21. Both ends of the sheet yarn profile 21 along the Y-axis direction are provided with fan-shaped adhesive strips 22 on the side of the X-axis direction closer to the outside. The end of the second limiting part 12 is provided with a frame sealing adhesive strip 23 on the side of the X-axis direction closer to the inside. The fan-shaped adhesive strip 22 and the frame sealing adhesive strip 23 are in contact and connected to form a first sealing structure 24.

[0036] The two ends of the sheet profile 21 in the Y-axis direction form water accumulation cavities 25 with the exterior profile 1 of the window frame.

[0037] The exterior window frame profile 1, being part of the outer frame material, is positioned near the exterior and used to fix the screen structure 2, ensuring its stability. The exterior window frame profile 1 has a first limiting part 11 and a second limiting part 12 extending along the X-axis and Y-axis respectively. A first installation area 13 is formed between the first limiting part 11 and the second limiting part 12. These two parts together define the installation boundary of the screen structure 2, ensuring its correct positioning within the exterior window frame profile 1. The first limiting part 11 and the second limiting part 12 serve as fixing points for the screen structure 2, securing it to the exterior window frame profile 1 with various fasteners to prevent displacement or detachment of the screen 214. The first installation area 13 provides a convenient space for the screen structure 2, making adjustments, maintenance, or replacement of the screen 214 easier.

[0038] The first sealing structure 24, formed by the contact and connection between the sash sealing strip 22 and the frame sealing strip 23, provides a good sealing effect, preventing external moisture, dust, and insects from entering the room through window gaps. Since the sash sealing strip 22 is installed on the mesh profile 21, which is made of a slender material from the mesh structure 2 and is not inherently shock-resistant, the tight connection between the sash sealing strip 22 and the frame sealing strip 23 increases the door and window's resistance to damage and improves overall safety.

[0039] The water-collecting cavity 25 formed by the two ends of the mesh profile 21 and the exterior profile 1 of the window frame increases in volume because the additional screen sash 3 in the mesh structure 2 is eliminated in this inward-tilting sliding window. The water-collecting cavity 25 serves as a drainage channel for this inward-tilting sliding window, guiding water entering the exterior profile 1 of the window frame to the outside, preventing rainwater from accumulating inside the exterior profile 1 of the window frame, and improving the waterproof performance of the door and window. Furthermore, the water-collecting cavity 25 helps keep the exterior profile 1 of the window frame dry, avoiding material corrosion and damage caused by long-term moisture accumulation.

[0040] Furthermore, the sheet profile 21 has a stop strip 26 on the side closer to the interior in the X-axis direction. The stop strip 26 is used to abut against the glass sash in the inward tilt-and-turn window to form a second sealing structure 27.

[0041] The sealing strip 26 provides direct contact between the window sash and the glass sash, forming a tight second seal 27 to reduce the penetration of moisture and dust. Made of elastic rubber or silicone, the sealing strip 26's contact with the glass sash increases the inward tilt-and-turn window's resistance to damage, improving safety. Simultaneously, the sealing design prevents pets or children from accidentally opening the window, preventing potential safety hazards.

[0042] Furthermore, the gauze profile 21 is provided with a detachable hinge structure 251 in the water accumulation cavity 25 on one side of the Y-axis direction. The hinge structure 251 includes a first movable part 252 and a second movable part 253 that are respectively connected to the window frame exterior profile 1 and the gauze profile 21. The ends of the first movable part 252 and the second movable part 253 near the interior are hinged to each other.

[0043] The system incorporates a detachable hinge structure 251 within the water collection cavity 25. This detachable hinge structure 251 allows users to easily remove the screen panel 21 for cleaning, maintenance, or periodic replacement of the screen 214. The first movable part 252 and the second movable part 253 facilitate the removal of the screen panel 21 from the exterior window frame profile 1. The ends of the first movable part 252 and the second movable part 253 near the interior are hinged together, resulting in smoother opening and closing of the screen panel 21 and improved user experience. Furthermore, placing the hinge structure 251 within the water collection cavity 25 helps in the periodic inspection and cleaning of any water that may remain in the cavity, preventing water accumulation from corroding the exterior window frame profile 1.

[0044] Furthermore, the sheath profile 21 is provided with a lockable safety lock structure 211, which is lockably connected to the exterior profile 1 of the window frame.

[0045] The safety lock structure 211 provides an additional security layer for the mesh profile 21, making doors and windows more difficult to open from the outside and improving the security of the home or building. Additionally, for families with children, the safety lock structure 211 can prevent children from accidentally opening doors and windows, thus avoiding potential falls.

[0046] Furthermore, the yarn profile 21 is also equipped with a magnetic attraction structure.

[0047] The magnetic structure on the mesh profile 21 utilizes the principle of attraction between opposite poles of magnets, allowing the mesh profile 21 to automatically adhere to the exterior profile 1 of the window frame, thus providing mosquito, dust, and wind protection. The magnetic structure can consist of magnetic strips that use magnetic force to fix the mesh profile 21 to the exterior profile 1 of the window frame, allowing for easy opening and closing during use.

[0048] Furthermore, the mesh profile 21 has a mesh fan slot 212 with an opening facing the outside. The opening of the mesh fan slot 212 does not protrude beyond the outer edge of the window frame exterior profile 1 in the X-axis direction. The mesh fan slot 212 is used to install the mesh assembly 213.

[0049] The screen sash groove 212 faces outwards, preventing small insects such as mosquitoes from entering the room and also helping to block outdoor dust and sand, reducing indoor pollution. The opening of the screen sash groove 212 does not protrude from the outer edge of the window frame's exterior profile 1 in the X-axis direction, which facilitates the embedding of the screen 214 within the window frame's exterior profile 1 and ensures the stability of the screen 214's installation.

[0050] Furthermore, the mesh assembly 213 includes a mesh 214, a sheet of mesh 215 for fixing the mesh 214, and a sheet of mesh adhesive strip 216 and a sheet of mesh pressing line 217 disposed on the side of the sheet of mesh 215 near the outside. The sheet of mesh adhesive strip 216 and the sheet of mesh pressing line 217 are used to fix the sheet of mesh 215.

[0051] The mesh assembly 213 includes a mesh 214, sheet mesh 215 for fixing the mesh 214, and sheet mesh adhesive strip 216 and sheet mesh pressure line 217 disposed on the side of the sheet mesh 215 near the outside. The mesh 214 can be supported by fine fiber material, which can block mosquitoes and dust from entering the room, while allowing air circulation and maintaining indoor ventilation. The sheet mesh 215 is tightly combined with the mesh 214 to ensure that the mesh 214 is flat and not easily deformed or shifted. The sheet mesh adhesive strip 216 is used to further fix the mesh 214, ensuring a tight fit between the mesh 214 and the sheet mesh 215, preventing mosquitoes and other insects from entering the room through gaps. The sheet mesh pressure line 217 applies pressure to make the mesh 214 flatter and improve the stability of the overall structure.

[0052] Furthermore, the yarn fan slot 212 includes a first slot 218 and a second slot 219 arranged side by side in the X-axis direction. The width of the first slot 218 in the X-axis direction is smaller than the width of the second slot 219 in the X-axis direction, and the length of the first slot 218 in the Y-axis direction is smaller than the length of the second slot 219 in the Y-axis direction. The first slot 218 is used to set the yarn sheet 215 and the mesh 214, and the second slot 219 is used to set the yarn sheet adhesive strip 216 and the yarn sheet pressing line 217.

[0053] The first slot 218 and the second slot 219, arranged side-by-side along the X-axis in the screen sash slot 212, utilize space more effectively. The smaller first slot 218 is specifically designed for the mesh 215 and screen mesh 214, while the larger second slot 219 is used for the mesh adhesive strip 216 and mesh pressure line 217, resulting in a more compact structure. Distinguishing between the first slot 218 and the second slot 219 helps clarify their respective functions. The second slot 219, being larger than the first slot 218, can accommodate the mesh adhesive strip 216 and mesh pressure line 217, thus improving the sealing performance between the screen mesh assembly 213 and the exterior profile 1 of the window frame, preventing insects and dust from entering the room through gaps.

[0054] Secondly, an exterior window frame profile 1 is used in any of the above-mentioned inward tilting and sliding windows. The exterior window frame profile 1 extends a first limiting part 11 and a second limiting part 12 in the X-axis direction and the Y-axis direction, respectively. A first installation area 13 is formed between the first limiting part 11 and the second limiting part 12. The first installation area 13 is used to install the screen structure 2. A frame sealing strip 23 is provided at the end of the second limiting part 12 on the side closer to the interior in the X-axis direction. The frame sealing strip 23 is used to abut against and connect with the sash strip 22 on the screen structure 2 to form a first sealing structure 24.

[0055] The exterior window frame profile 1, being part of the outer frame material, is positioned near the exterior and used to fix the screen structure 2, ensuring its stability. The exterior window frame profile 1 has a first limiting part 11 and a second limiting part 12 extending along the X-axis and Y-axis respectively. A first installation area 13 is formed between the first limiting part 11 and the second limiting part 12. These two parts together define the installation boundary of the screen structure 2, ensuring its correct positioning within the exterior window frame profile 1. The first limiting part 11 and the second limiting part 12 serve as fixing points for the screen structure 2, securing it to the exterior window frame profile 1 with various fasteners to prevent displacement or detachment of the screen 214. The first installation area 13 provides a convenient space for the screen structure 2, making adjustments, maintenance, or replacement of the screen 214 easier.

[0056] Thirdly, a mesh structure 2 is applied to an inward-tilting side-sliding window according to any of the above. The mesh structure 2 includes a mesh profile 21. Both ends of the mesh profile 21 along the Y-axis direction are provided with a sash adhesive strip 22 on the side of the X-axis direction closer to the outside. The sash adhesive strip 22 is used to contact and connect with the frame sealing adhesive strip 23 on the outdoor profile 1 of the window frame to form a first sealing structure 24.

[0057] The first sealing structure 24, formed by the contact and connection between the sash sealing strip 22 and the frame sealing strip 23, provides a good sealing effect, preventing external moisture, dust, and insects from entering the room through window gaps. Since the sash sealing strip 22 is installed on the mesh profile 21, which is made of a slender material from the mesh structure 2 and is not inherently shock-resistant, the tight connection between the sash sealing strip 22 and the frame sealing strip 23 increases the door and window's resistance to damage and improves overall safety.

[0058] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
