Description

TECHNICAL FIELD

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

[0002] The out-opening window is a common type of window in buildings. In the traditional out-opening window structure, the sash is usually overlapped on the outside of the window frame when closed. This structure causes the frame profile of the sash and the fixed window frame or jamb profile to form a step on the outdoor side, and the visible widths of the two are also significantly different, resulting in a serious visual asymmetry between the opening position (movable window) and the fixed position (fixed window), which does not meet the aesthetic demand of modern architecture for minimalism and unity.

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

[0004] The purpose of the present application is to provide a full-hidden out-opening window with symmetrical opening position and fixed position, which solves the problem of appearance asymmetry between the opening position and the fixed position of the out-opening window in the prior art and the problem of traditional screen window destroying the overall aesthetics. 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 full-hidden out-opening window with symmetrical opening position and fixed position provided by the present application comprises a main frame, a fixed window, a jamb and a movable window. The movable window is accommodated in the main frame and the jamb in the closed state, and the width of the visible surface of the frame of the movable window towards the indoor side is the same as the width of the visible surface of the frame of the fixed window towards the indoor side in the closed state. The width of the visible surface of the jamb towards the indoor side is the same as the width of the visible surface of the main frame. The spacing between the frame of the visible surface of the movable window and the frame of the visible surface of the jamb on the outdoor side is D1, and the spacing between the frame of the visible surface of the movable window and the frame of the visible surface of the main frame on the outdoor side is D2, D1=D2. The jamb or the fixed window towards the frame of the movable window defines a receiving cavity on the indoor side. It also comprises a retractable screen window, which is accommodated in the receiving cavity in the storage state.

[0006] Preferably, the retractable screen is a folding screen or a roller blind screen.

[0007] Preferably, it also includes a concealed hinge, which is disposed in a hardware groove between the mullion or the fixed window and the movable window, and is concealed when the movable window is in the closed state.

[0008] Preferably, it also includes a handle, which is a side-mounted handle, disposed on the frame of the movable window, and can be stored and hidden within the frame of the movable window.

[0009] Preferably, a concealed stepped floor drain structure is provided on the mullion at the bottom of the movable window or on the frame of the fixed window.

[0010] Preferably, the concealed stepped floor drain drainage structure includes a first opening and a second opening. The first opening is located on the bottom wall of the horizontal groove of the mullion or the main frame on the outdoor side, and the second opening is located on the recessed end wall between the mullion or the main frame and the movable window on the outdoor side. Both the first opening and the second opening are connected to the inner cavity of the mullion or the main frame profile.

[0011] Preferably, the mullion and the main frame on the indoor side protrude beyond the fixed window and the movable window.

[0012] Preferably, the visible surfaces of the frames of the fixed window and the movable window on the indoor side are inclined surfaces that slope inward from the point where the mullion and the main frame are flush.

[0013] The application employs the above technical solution and has at least the following beneficial effects: By concealing the operable window within the main frame and mullion when closed, and by specifically designing the visible width and spacing of the operable window, fixed window, mullion, and main frame, the fixed and operable window sections present a symmetrical and unified visual effect both indoors and outdoors when closed. This completely solves the visual asymmetry problem caused by structural differences in traditional outward-opening windows, greatly enhancing the architectural aesthetics. By setting a receiving cavity within the mullion or fixed window frame on the indoor side and storing the retractable screen within it, the screen is completely hidden, maintaining both functionality and the purity of design and simplicity of appearance. Furthermore, by concealing the hinges, handles, and drainage system, a high-quality door and window solution with a high degree of unity between function and form is provided.

[0014] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[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 embodiment provides a fully concealed outward-opening window with symmetrical opening and fixed positions. This outward-opening window aims to achieve perfect visual symmetry between the fixed window 2 and the movable window 4 when the window is closed, while concealing functional accessories such as screens, thus achieving an overall minimalist and aesthetically pleasing visual effect.

[0020] Please see Figure 1 The figure illustrates the overall structure of the outward-opening window provided in this application embodiment when closed. As shown, when the window is closed, whether viewed from the indoor or outdoor side, the operable window portion and the fixed window portion appear as a continuous, flat, and uniformly wide whole. There are no visible hinges, handles, or drain hole covers, achieving a high degree of visual unity and minimalist aesthetics.

[0021] To more clearly reveal its internal structure and implementation principles, such as Figure 1 As shown, the outward-opening window mainly includes an outer main frame 1, a fixed window 2, a mullion 3 for dividing the window area and providing structural support, and an operable window 4. The operable window 4 is rotatably connected to the main frame 1 or the mullion 3 via a hinge mechanism to open to the outside.

[0022] A core design element of this embodiment lies in the installation method of the movable window 4 in the closed state and its dimensional relationship with surrounding components. Specifically, as follows: Figure 1 As shown in Figure 2, when the movable window 4 is closed, its entire frame is contained within the installation space enclosed by the main frame 1 and the mullion 3. This "embedded" structure is fundamentally different from the "external" structure of traditional outward-opening windows, which overlap with the outside of the window frame when closed. It is precisely based on this embedded structure that the conditions for achieving visual symmetry are created.

[0023] To achieve visual symmetry, the profile cross-sections of each component were precisely designed in this embodiment. In a specific implementation, both the frame profile of the movable window 4 and the mullion 3 are made of extruded aluminum alloy. By design, when the movable window 4 is closed, the width of its frame's visible side facing the interior is the same as the width of the fixed window 2's frame's visible side facing the interior, as shown in the attached figure. Figure 1 The visible width of the frame of the movable window 4 facing the interior is d1, while the visible width of the frame of the fixed window 2 facing the interior is d2, where d1 = d2. For example, this width ranges from 25 mm to 45 mm, and can be specifically set to 31 mm. Correspondingly, the visible width of the mullion 3 and the main frame 1 on the interior side is also designed to be the same. For example, the visible width of the mullion 3 on the interior side is d3, while the visible width of the main frame 1 on the interior side is d4, where d3 = d4. This width ranges from 30 mm to 55 mm, and can be set to 42 mm for example. Thus, when looking from inside the room towards the windows, the widths presented to the observer are all equal for the frames of the movable window 4 and the fixed window 2, as well as for the mullion 3 and the main frame 1, creating a neat and harmonious sense of array.

[0024] For the outdoor side, to achieve the same symmetrical visual effect, in addition to setting the frames of the movable window 4 and the fixed window 2, as well as the mullion 3 and the main frame 1, to be of the same size as described above, this embodiment of the application also achieves this by controlling the gap size. For example... Figure 1 Alternatively, as shown in Figure 2, on the outdoor side, a preset, uniform gap is maintained between the outer surface of the frame of the movable window 4 and the outer surface of the frame of the fixed window 2 and the outer surface of the mullion 3. The width of this gap is defined as D1. Simultaneously, a preset, uniform gap is also maintained between the outer surface of the frame of the movable window 4 and the outer surface of the frame of the fixed window 2 and the outer surface of the main frame 1. The width of this gap is defined as D2. Through precise manufacturing and installation control, the values ​​of spacing D1 and spacing D2 are equal (D1=D2). This equidistant design makes the window appear on the outdoor facade as a glass matrix divided by slender, uniform lines, avoiding the chaotic feeling of inconsistent widths and unevenness caused by structural overlaps in traditional windows. It also possesses a sense of symmetry.

[0025] Another core design feature of this embodiment lies in the concealment of functional accessories. For example... Figure 1Alternatively, as shown in Figure 2, to perfectly integrate and conceal the screen, a receiving cavity 5 is integrally defined within the profile of the mullion 3 or the fixed window 2, particularly on the side facing the movable window 4, through a profile extrusion process. This receiving cavity 5 utilizes the structural thickness of the mullion 3 or the fixed window 2 profile to form an internal space for accommodating the retractable screen 6. In this embodiment, the retractable screen 6 is specifically a folding screen, comprising a pre-folded mesh and frame components for fixing and guiding the mesh's movement. In its retracted state, the entire folding screen is completely compressed and housed within the receiving cavity 5, making it completely invisible from the outside. When needed, the user can pull out the screen's pull bar from the opening of the receiving cavity 5, unfolding it to cover the ventilation opening formed by the opening of the movable window 4; when not in use, it can be pushed back, and the mesh automatically folds and retracts into the receiving cavity 5. Through this design, the screen function is seamlessly integrated into the window structure without compromising the window's minimalist appearance. It is understood that the receiving cavity 5 can also be set in the frame of the fixed window 2, or in other embodiments it can be set in the profile of the main frame 1, as long as it can achieve the concealment and storage of the retractable screen window 6.

[0026] In some embodiments, the retractable screen 6 can also be a roller screen.

[0027] To further enhance the overall integrity and aesthetics of the window, this embodiment also incorporates a concealed design for other hardware and functional structures. (See attached image.) Figure 4 , 9 As shown in Figures 1 and 13, the connection between the movable window 4 and the main frame 1 or the mullion 3 uses a concealed hinge 9. It should be noted that the concealed hinge 9 is shown in these three figures for illustrative purposes. The concealed hinge 9 is located at the top and / or bottom of the movable window 4. This concealed hinge 9 includes two bases fixed to the frame of the movable window 4 and the frame of the main frame 1, respectively, and a multi-link mechanism connecting the two bases. During installation, the two bases are respectively embedded and fixed in the hardware slots pre-set for the hardware. When the movable window 4 is closed, the entire hinge linkage mechanism folds and retracts into the gap between the movable window 4 and the main frame 1, making the hinge invisible from both inside and outside, thus ensuring the continuity and purity of the window frame lines.

[0028] The handle in this embodiment also features a retractable design. The retractable handle 7 is mounted on the side frame of the movable window 4. This handle is side-mounted, and its operating part (e.g., a flat wrench) is connected via a pivot to a base that can be stored in a pre-set cavity inside the frame of the movable window 4. When the window needs to be opened or closed, the handle wrench can be flipped out of the cavity, then the handle can be rotated to drive the internal locking mechanism, and then the movable window 4 can be pushed or pulled. After the window is closed or opened to a predetermined angle, the handle wrench can be flipped back and pushed into the cavity, making its outer surface flush with the side of the frame of the movable window 4. This design allows the handle to be completely hidden when the window is not in operation, avoiding the abruptness of traditional handles on the window sash surface.

[0029] Furthermore, to solve the drainage problem and maintain a smooth appearance, this embodiment also employs a concealed drainage solution. A concealed stepped floor drain structure 8 is installed on the bottom profile of the main frame 1 or the mullion 3. This structure can efficiently drain rainwater that seeps into the gap between the window frame and the window sash. Specifically, the concealed stepped floor drain structure 8 includes at least two key openings: a first opening 10, located on the bottom wall of the horizontal groove of the outdoor main frame 1 (i.e., the groove of the main frame 1 or mullion 3 that receives the bottom edge of the movable window 4), used to collect rainwater flowing in from the gap between the window sash and the window frame; and a second opening 11, located on a relatively concealed concave end wall 13 between the outdoor main frame 1 or mullion 3 and the movable window 4. Both the first opening 10 and the second opening 11 are connected to a pre-set drainage cavity inside the main frame 1 profile. When rainwater enters the gaps in the window frame, it collects in the horizontal groove, flows into the inner cavity of the profile through the first opening 10, and then, guided by the inner cavity, finally drains to the outside through the lower and more concealed second opening 11. The entire drainage process is completed inside the profile, eliminating the need for drainage holes with covers on the outer surface of the profile, thus ensuring the integrity and aesthetics of the window facade.

[0030] As an optional implementation method, see attached... Figures 6-9 As shown, on the interior side, the profile surfaces of the mullion 3 and the main frame 1 can be designed to slightly protrude from the surfaces of the operable window 4 and the fixed window 2, creating a subtle sense of depth. Simultaneously, combined with the attached... Figure 10 - Appendix Figure 13 As shown, the visible surfaces of the frames of the fixed window 2 and the movable window 4 on the interior side can be designed as inclined surfaces that slope inwards from the position flush with the mullion 3 and the main frame 1 towards the interior of the glass. This inclined surface design with chamfers not only produces a slimmer and more three-dimensional effect visually, but also creates subtle changes in light and shadow under light, enhancing the product's sophistication.

[0031] In summary, this embodiment, through systematic and integrated design of the window structure, profile cross-section, hardware, and functional accessories, successfully achieves an outward-opening window that is symmetrical and flat both inside and outside when closed, completely concealing functions such as screens, hinges, handles, and drainage. During operation, users can easily open the movable window 4 for ventilation via the concealed handle 7, and pull out the retractable screen 6 from the receiving cavity 5 for mosquito protection as needed. This product is not only fully functional but also achieves a new level of aesthetics, meeting the stringent requirements of modern high-end architecture for minimalist and unified facades.
