Abstract
Description
Technical Field
[0001] This utility model belongs to the field of door and window structure, specifically relating to an anti-interference compensation structure for an inward-opening sash frame. Background Technology
[0002] With the continuous updating of modern architectural design concepts, people have placed higher demands on the aesthetics and comfort of buildings. One significant trend is the increasing proportion of window and door area in buildings. Large windows not only allow ample natural light to enter, creating a bright and warm indoor atmosphere, but also enhance the visual connection between indoor and outdoor spaces, giving residents a wide view and allowing for more full interaction with the outside world. Typically, floor-to-ceiling windows have a fixed frame at the bottom and an operable sash at the top to meet ventilation needs. When the sash is open, fresh air flows into the room and stale air is expelled, maintaining fresh indoor air without affecting the overall transparency and lighting of the window.
[0003] Inward-opening windows are becoming a preferred solution in modern architecture due to their safety and ease of operation. When opened, the frame rotates inwards, requiring careful consideration of its compatibility with interior décor. Interior components such as curtain boxes have a particularly significant impact on the opening process: when the frame opens to an angle exceeding 45°, the upper edge of the frame is highly susceptible to colliding with the curtain box in the ceiling, leading to wear on the frame profile or deformation of the curtain track. To address this interference issue, existing designs sometimes employ fixed transoms to enclose the upper part of the window, avoiding the curtain box's location. However, adding a fixed transom structure requires additional space for window frame fabrication and directly reduces the effective opening area by 15%–20%, significantly impacting room ventilation efficiency and the overall appearance of the window. Utility Model Content
[0004] This utility model addresses the above-mentioned problems by providing an inward-opening fan frame compensation structure that ensures the opening area of the fan frame and has a simple structure.
[0005] This utility model adopts the following technical solution: it includes a window frame and a sash frame, characterized in that it further includes a compensating profile fixedly connected to the window frame. The interior surface of the compensating profile is flush with the interior surface of the window frame. A positioning clip is provided on the interior side of the upper surface of the compensating profile. An overlapping edge is provided on the lower edge of the exterior side of the window frame. An overlapping step is provided on the exterior side of the compensating profile corresponding to the overlapping edge. An inner sealing edge is provided on the outer side of the interior surface of the sash frame corresponding to the compensating profile. An outer sealing edge is provided on the lower part of the exterior side of the compensating profile. A sealing step is provided on the inner side of the sash frame corresponding to the outer sealing edge.
[0006] As a preferred embodiment of this utility model, the window frame, sash frame and compensating profile are all made of thermally broken aluminum profile, and corresponding intermediate sealing strips are provided at the thermal insulation strip below the compensating profile and at the thermal insulation strip above the sash frame.
[0007] As another preferred embodiment of this utility model, edge sealing strips are provided between the outer sealing edge and the sealing step, between the overlapping edge and the overlapping step, and between the inner sealing edge and the inner surface of the compensating profile.
[0008] As a third preferred embodiment of this utility model, the window frame and the compensation profile are connected by screws.
[0009] As a fourth preferred embodiment of this utility model, the compensating profile is provided with cavities on both the indoor and outdoor sides.
[0010] The beneficial effects of this utility model are as follows: This utility model only adds a small-sized compensating profile to the opening part of the window sash, which can effectively prevent the window sash from interfering with or colliding with indoor components such as the curtain box when it is opened, while maximizing the opening height of the window sash, which is conducive to improving the indoor ventilation effect.
[0011] Furthermore, this utility model has a simple and reasonable structure. It achieves precise positioning of the compensating profile and the window frame through the indoor positioning card and the outdoor overlapping step, and is further secured by screws to ensure a stable and reliable connection between the compensating profile and the window frame. With the addition of a multi-seal structure, it can ensure good airtightness and watertightness of the window as a whole, making it safe and practical. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0020] This utility model includes a window frame 2, a sash frame 3, and a compensating profile 1 fixedly connected to the window frame 2. The interior surface of the compensating profile 1 is flush with the interior surface of the window frame 2. A positioning clip 13 is provided on the upper surface of the compensating profile 1 on the interior side. An overlapping edge 9 is provided on the lower edge of the exterior side of the window frame 2. An overlapping step 8 is provided on the exterior side of the compensating profile 1 corresponding to the overlapping edge 9. An inner sealing edge 10 is provided on the outer side of the interior surface of the sash frame 3 corresponding to the interior surface of the compensating profile 1. An outer sealing edge 11 is provided on the lower part of the exterior side of the compensating profile 1. A sealing step 12 is provided on the inner side of the sash frame 3 corresponding to the outer sealing edge 11.
[0021] The window frame 2, sash frame 3 and compensating profile 1 are all made of thermally broken aluminum profiles. Corresponding intermediate sealing strips 7 are provided at the thermal insulation strip below the compensating profile 1 and at the thermal insulation strip above the sash frame 3.
[0022] A side sealing strip 6 is provided between the outer sealing edge 11 and the sealing step 12, between the overlapping edge 9 and the overlapping step 8, and between the inner sealing edge 10 and the inner surface of the compensation profile 1.
[0023] The window frame 2 and the compensating profile 1 are connected by screws 4.
[0024] The compensating profile 1 has cavities 5 on both the indoor and outdoor sides.
[0025] like Figure 5 As shown, in traditional floor-to-ceiling window designs, the upper edge of the window sash 3 is usually flush with the upper horizontal frame of the window frame 2. When the window sash 3 opens to a certain angle inwards, if a curtain box is installed on the ceiling, the upper edge of the window sash 3 will collide with the curtain box, causing damage to the curtain box or the window sash. This existing technology, with its window sash extending to the ceiling, suffers from the aforementioned problem of interference with the curtain box, and the corresponding solutions (such as adding a fixed transom) reduce the opening area of the window sash.
[0026] See Figures 1-4This utility model provides an inward-opening window sash compensation structure to solve the aforementioned interference problem. The structure includes a window frame 2, a sash frame 3, and a compensation profile 1. The compensation profile 1 is fixedly connected to the upper part of the window frame 2 by screws 4. After installation, it is flush with the interior surface of the window frame 2, extending the height of the window frame when the sash is open. The upper surface of the compensation profile 1, facing the interior, has a positioning clip for installation. During installation, the compensation profile 1 can be positioned against the interior of the window frame 2 using this positioning clip. The lower exterior edge of the compensation profile 1 has an overlapping step 8, which can interlock with the overlapping edge 9 of the lower exterior edge of the window frame 2, forming a flat and tight overlapping connection between the compensation profile 1 and the window frame 2 on the outside. Through the positioning clip on the interior side and the overlapping structure on the exterior side, the compensation profile 1 is positioned and supported during installation. Then, the compensation profile 1 is firmly fixed to the window frame 2 by screws 4, achieving a reliable connection.
[0027] An inner sealing edge 10 is provided on the outer side of the upper edge of the sash frame 3. When the window sash is closed, the inner sealing edge 10 is flush with the inner side of the compensating profile 1, forming the first seal. The lower part of the outer side of the compensating profile 1 extends integrally to form an outer sealing edge 11. A sealing step 12 is provided at the corresponding position of the window sash 3. When the window sash is closed, the outer sealing edge 11 and the sealing step 12 fit together to form the second seal. Preferably, edge sealing strips 6 are installed between the inner sealing edge 10 and the inner surface of the compensating profile 1, between the overlapping edge 9 and the overlapping step 8, and between the outer sealing edge 11 and the sealing step 12, to further enhance the sealing effect at the above locations and prevent air and water from entering through the gaps.
[0028] In addition, to ensure the thermal insulation and sealing performance between the compensating profile 1 and the sash frame 3, both the sash frame 3 and the compensating profile 1 adopt a thermally broken aluminum profile structure. A corresponding intermediate sealing strip 7 is provided at the joint of the thermal insulation strip to seal the gap between the sash frame and the compensating profile, preventing air and rainwater from seeping in. Both the indoor and outdoor sides of the compensating profile 1 are provided with cavities 5. These cavities 5 match the original cavity of the sash frame 3 profile and can be used to install thermal insulation strips and reduce the weight of the profile.
[0029] Through the above structural design, this utility model adds a small amount of compensating profile 1 to the window sash opening section. The compensating profile 1 occupies little space, increasing the window sash area. Specifically, the width of the compensating profile only needs to be 60mm to meet usage requirements. However, to meet usage requirements, a fixed-beam form requires a minimum width of 300mm, which necessitates a 240mm reduction in window sash height. Furthermore, the compensating profile 1 is connected to the window frame 2 using screws 4 and a snap-fit positioning mechanism, ensuring the strength and stability of the connection between the compensating profile and the original window frame. Multiple sealing strips also ensure the overall airtightness and watertightness of the window after adding the compensating profile, without sacrificing the window's sealing performance. This utility model has a simple structure, is easy to install, and is suitable for various inward-opening window designs that require solving window sash interference problems without reducing ventilation area.

Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
