TECHNICAL FIELD

[0001] The present application relates to the technical field of doors and windows, in particular to a full-hidden inward-opening window with symmetrical opening position and fixed position. BACKGROUND

[0002] With the pursuit of minimalism aesthetics in modern architectural design, the appearance design of windows is paid more and more attention. In traditional inward-opening windows, the sash is usually lapped on the window frame on the indoor side, so that when the sash is closed, the sash plane will protrude from the window frame plane, forming a visual unevenness. In addition, the visible width of the sash profile is often different from that of the window frame profile, so that there is an obvious difference in appearance between the opening position (movable window) part and the fixed position (fixed window) part of the window, and the whole is asymmetric, which is difficult to meet the requirements of high-end buildings for simple and unified facade.

[0003] In addition, when a screen window is provided for a window, the traditional method is usually to attach the screen window as an independent component to the window, such as a fixed screen window integrally fixed on the outside of the window frame, a casement screen window additionally installed on the outside, or a roll-up screen window pulled up and down. These additional screen window structures will destroy the simplicity and aesthetics of the whole window. SUMMARY

[0004] The purpose of the present application is to provide a full-hidden inward-opening window with symmetrical opening position and fixed position, which solves the problems of asymmetry in appearance between the opening position and the fixed position of the existing inward-opening window and the destruction of the overall aesthetics by the traditional screen window. The preferred technical solutions in the many technical solutions provided by the present application can produce many technical effects, which are described in detail below.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: The present application provides a full-hidden inward-opening window with symmetrical opening position and fixed position, comprising a main frame, a fixed window, a mullion and a movable window. The movable window is accommodated in the main frame and the mullion in the closed state, and the visible surfaces of the frame profile of the movable window towards the indoor or outdoor are coplanar with the visible surfaces of the frame profile of the fixed window towards the indoor or outdoor, respectively. The visible width of the frame profile of the movable window on the indoor side is the same as the visible width of the frame profile of the adjacent fixed window. The distance between the frame profiles of the visible surfaces on the indoor side is the same. The profile of the main frame or the fixed window of the inward-opening window is internally provided with an accommodating cavity, and the accommodating cavity is provided with a storable screen window.

[0006] Preferably, the spacing between the frame of the visible surface of the movable window and the frame of the visible surface of the fixed window on the indoor side is H1, and the spacing between the frame of the visible surface of the movable window and the frame of the visible surface of the fixed window on the indoor side is H2, H1=H2.

[0007] Preferably, the visible surface of the partial frame of the mullion on the indoor side is coplanar with the visible surface of the movable window and the fixed window, the spacing between the frame of the visible surface of the movable window and the fixed window and the frame of the visible surface of the mullion is D1, and the spacing between the frame of the visible surface of the movable window and the fixed window and the frame of the visible surface of the main frame on the indoor side is D2, D1=D2.

[0008] Preferably, the mullion of the bottom of the movable window or the frame of the fixed window is provided with a hidden drainage structure.

[0009] Preferably, the hidden drainage structure comprises a first opening and a second opening, the first opening is a vertical hole opened on the outer frame of the mullion or the main frame on the outdoor side, and the second opening is opened on the side wall of the outer frame of the mullion close to the movable window.

[0010] Preferably, the storable screen window is a folding screen window or a rolling screen window.

[0011] Preferably, it further comprises a hidden hinge, which is arranged in the hardware slot between the mullion or the fixed window and the movable window and is hidden when the movable window is in the closed state.

[0012] Preferably, it further comprises a handle, which is a side-mounted handle arranged on the frame of the movable window and can be storable and hidden in the frame of the movable window.

[0013] The above technical scheme is adopted in the present application, and at least the following beneficial effects are achieved: By systematically integrating four functions of symmetrical visible surface, hidden screen window, hidden hardware and hidden drainage, the window in the closed state presents an ultimate simple appearance of pure flat, symmetry and no extra functional components from the indoor or outdoor observation, which meets the design requirements of modern high-end buildings. Meanwhile, while realizing the minimalist appearance, the built-in storable screen window and the efficient hidden drainage system completely retain the mosquito prevention and drainage functions of the window, solving the contradiction between the pursuit of beauty and the sacrifice of functionality or the destruction of beauty due to the increase of function in the prior art. In addition, the design of the storable side-mounted handle not only is beautiful, but also avoids the bumping or hanging to the curtain caused by the traditional handle, thereby improving the use experience. The scheme is based on the broken bridge aluminum alloy profile and multi-seal design, which guarantees the superior heat insulation, heat preservation, sound insulation, air tightness and water tightness performance of the whole window, ensures the stability and durability of the structure while realizing the highly integrated design.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0019] This application discloses a fully concealed inward-opening window with symmetrical opening and fixed positions. Through a systematic structural design, this window integrates the window's symmetrical aesthetics, screen function, hardware, and drainage system, achieving an extremely minimalist architectural appearance while ensuring excellent physical performance.

[0020] like Figure 1 As shown, the inward-opening window in this embodiment can be a double-leaf window, consisting of a main frame 1, a supporting mullion 3, a fixed window 2, and a movable window 4 that can be opened inwards. As a preferred embodiment, the main frame 1, mullion 3, and movable window 4 are all made of thermally broken aluminum alloy profiles. These profiles use high-strength thermal break strips to separate the indoor and outdoor aluminum alloy sections, effectively blocking heat conduction paths and thus giving the entire window excellent thermal insulation performance. Correspondingly, the interior of the profile is designed with a complex cross-section containing multiple chambers. This design enhances the structural strength and wind pressure resistance of the profile while also providing the necessary space for integrating various concealed functional components.

[0021] A core technical feature of this embodiment lies in achieving a high degree of symmetry and a visually flat effect when the window is closed. Specifically, when the movable window 4 is in the closed position, it is precisely contained within the space enclosed by the main frame 1 and the mullion 3. Figure 1The horizontal sectional structure of the movable window 4 shows that the frame profile of the movable window 4 is in the same plane with the corresponding visible surface of the frame profile of the fixed window 2, that is, the design of "coplanar" is achieved. This design eliminates the height difference between the indoor and outdoor caused by the overlapping of the sash on the window frame in the traditional inward opening window, so that the window appears to be a complete and smooth facade from both indoor and outdoor.

[0022] In order to further strengthen the symmetry aesthetics, the visible width of each component is strictly designed in this embodiment. As shown in Figure 1 , the visible width of the frame profile of the movable window 4 is exactly the same as that of the fixed window 2 from the indoor side. In an exemplary embodiment, the width can be designed to be 40mm. This equal width design makes it difficult to distinguish the opening part from the fixed part of the window visually, breaks the appearance of the traditional window caused by the functional partition, and achieves perfect symmetry in vision.

[0023] As a preferred limitation of this symmetry, as shown in the accompanying Figures 1-4 , the side of the mullion 3 part facing the indoor side is flush with the movable window 4 and the fixed window 2, and the spacing between the visible frame profile of the movable window 4 and the fixed window 2 and the visible frame profile of the mullion 3 can be set as D1, and the spacing between the visible frame profile of the movable window 4 and the fixed window 2 on the indoor side and the visible frame profile of the main frame 1 can be set as D2, and D1=D2 can be achieved by design. This equal spacing design makes the visual segmentation lines inside the window uniform and harmonious, further improving the overall order and aesthetic value.

[0024] In other embodiments, as shown in the accompanying Figures 5-8 , it can be understood that the indoor side of the mullion 3 part is hidden in the indoor position, and there is no part structure flush with the movable window 4 and the fixed window 2, so that the indoor side of the movable window 4 and the fixed window 2 are directly adjacent, and the spacing between the visible frame profile of the movable window 4 and the fixed window 2 on the indoor side and the visible frame profile of the main frame 1 can be set as H1, and the spacing between the visible frame profile of the movable window 4 and the visible frame profile of the fixed window 2 on the indoor side can be set as H2, and H1=H2 can be achieved by precise processing and assembly.

[0025] Another core technical feature of this embodiment is the hidden integration of the screen window. In order to provide the anti-mosquito function without destroying the minimalist appearance of the window, the storage space of the screen window is ingeniously arranged inside the profile. For details, please refer to Figure 1 , 3, 6, 8, a receiving cavity 5 is integrally formed inside the profile of the mullion 3 by an extrusion process. The receiving cavity 5 is precisely designed in size and shape to accommodate a retractable screen window. In this embodiment, the retractable screen window is specifically a retractable screen window 6, which includes concertina-folded screen mesh, a pulling profile and a guide rail system. When not in use, the retractable screen window 6 can be completely retracted and pushed into the receiving cavity 5 of the mullion 3, with the end face of the pulling profile flush with the surface of the mullion 3, thus completely hidden from view. When needed, the user can pull the retractable screen window 6 out of the receiving cavity 5, unfold it along the tracks pre-designed in the upper and lower profiles of the main frame 1, until it covers the entire window opening area and is locked on the buckle on one side of the casement window 4. This design allows the screen window to be unfolded for use when needed, and completely retracted and hidden when not in use, thus balancing the practical function and overall aesthetics.

[0026] In another embodiment, the retractable screen window 6 is specifically a folding screen window, which includes pre-folded screen mesh and a border member for fixing and guiding the movement of the screen mesh. In the retracted state, the entire folding screen window is completely compressed and accommodated in the receiving cavity 5, completely invisible from the outside. When needed, the user can pull the pulling beam of the screen window out of the opening of the receiving cavity 5, so that it unfolds and covers the ventilation opening formed after the casement window 4 is opened; when not in use, it is pushed back, and the screen mesh is automatically folded and retracted into the receiving cavity 5. Through this design, the screen window function is seamlessly integrated into the window structure without damaging the minimalist appearance of the window. It can be understood that the receiving cavity 5 can also be provided in the frame of the fixed window 2, or in the profile of the main frame 1 in other embodiments, as long as it can achieve the hidden retraction of the retractable screen window 6.

[0027] In order to achieve the effect of complete "full hiding", the hardware of this embodiment is also hidden. First, the hinge connecting the casement window 4 and the mullion 3 adopts a hidden hinge 10, as shown in Figure 2 and Figure 7 The hinge is installed in the hardware slot reserved between the casement window 4 and the mullion 3, and the structure design ensures that when the casement window 4 is closed, no part of the hinge is exposed to the indoor or outdoor view, thus ensuring the simplicity of the frame and sash joint. Second, the handle 11 for operating the opening and closing of the window sash also adopts a hidden design. As shown in Figure 1As shown, a handle 11 mounting cavity is provided on the side frame profile of the movable window 4. The handle 11 is a side-mounted handle, the main body of which is mounted in the cavity through a rotating or flipping mechanism. When not in use, the handle 11 can be completely flipped or pushed into the handle mounting cavity, so that its surface is flush with the side surface of the window sash profile and completely invisible from the front. When the window needs to be opened, the user can put his fingers into the reserved groove on the side of the profile to pull out the handle 11, rotate the handle 11 to drive the locking mechanism to unlock, and then pull the movable window 4 inward. This design not only significantly improves the aesthetic effect, but also effectively avoids the safety hazards that the traditional exposed handle 11 may hang on the curtain or cause human body bumps.

[0028] In addition, the embodiment also provides an efficient and aesthetic hidden drainage solution. Please refer to Figure 2 and the attached Figure 5 As shown. Compared with the traditional method of setting drainage holes on the outdoor side of the window and covering them, the embodiment sets a hidden drainage structure 7 on the frame of the mullion 3 or the fixed window 2. As shown by the arrows in Figure 2 、 4 , 5, 7, 9, when the rainwater enters the gap between the bottom of the movable window 4 and the lower window frame under the action of wind pressure, it will fall into the hidden drainage structure 7 due to the action of gravity. Water will flow smoothly along the preset path and eventually be discharged outside through the hidden drainage opening provided in an inconspicuous position such as the bottom or side of the lower window frame profile. As a specific implementation, the hidden drainage structure can include a first opening 8 provided on the outdoor side profile frame and a second opening 9 provided on the side wall close to the movable window sash. Water flows through these internally connected channels to be discharged, and there is no drainage hole cover visible from the outside. The first opening 8 is provided vertically through the outdoor side profile frame of the mullion 3 or the main frame 1. This way of penetrating the entire outdoor side profile frame from top to bottom allows water to flow inside the profile and be discharged through the opening at the bottom. This design ensures excellent water tightness while maintaining the integrity and purity of the window facade.

[0029] To ensure the sealing performance of the entire window, the embodiment provides multiple high-performance EPDM or silicone sealant strips at the overlapping parts of the main frame 1 and the movable window 4, the overlapping parts of the mullion 3 and the movable window 4, and the glass grooves where hollow glass is installed. These strips are fully compressed when the sash is closed, forming a reliable air and water tight barrier and effectively improving the sound insulation, dust prevention and energy saving effect of the window.

[0030] In summary, the embodiment integrates the four functions of symmetrical coplanar appearance, hidden screen window, hidden hardware and hidden drainage into one by systematic innovation design of profile structure, screen window, hardware and drainage system, thereby providing a full-hidden symmetrical inward opening window solution with minimalistic aesthetics, powerful functions and superior physical performance.
