A glass curtain wall window

Abstract

This invention relates to the field of window technology, specifically to a glass curtain wall window, comprising a mounting bracket, a glass panel, and a window frame. The mounting bracket and the window frame are rotatably connected via a damping pivot. The window frame is trapezoidal, wider at the top and narrower at the bottom, and vertical plates are provided on both sides of the window frame. This invention, through the coordinated use of a resilient metal connecting piece, vertical plates, and a drive assembly, allows the drive assembly to drive a worm gear when the window is opened. The rotating worm gear drives a pivot and a rotating rod to rotate. The rotating rod, through a guide block and a ring guide groove, moves a fixed sleeve. The moving fixed sleeve, through a long rod and a connecting rod, causes one end of the vertical plate to shift towards the window frame. After the vertical plate shifts, the entire window forms a trapezoidal shape, wider at the top and narrower at the bottom, similar to the window frame. When the window is opened, the outer corners of the window sash become smaller, thus preventing the outer corners of the window sash from easily encroaching on the rotation range of adjacent windows.

Description

Technical Field

[0001] This invention relates to the field of window technology, specifically to a glass curtain wall window. Background Technology

[0002] As the core window unit integrated into the building's glass curtain wall system, glass curtain wall windows, with their openable ventilation function, have become the mainstream choice for commercial office buildings, public buildings, and other scenarios because they can introduce outdoor air into the interior at an ideal angle and effectively prevent rainwater from entering the interior when the rain is not heavy and the wind is not strong.

[0003] In actual building design and construction, due to multiple factors such as building appearance, functional layout, and fire prevention and smoke exhaust regulations, outward-opening windows often need to be densely arranged in special structural locations. However, the rotating opening mechanism of outward-opening windows, with the top edge as the axis, makes it highly susceptible to interference between the opening trajectories of adjacent windows, leading to collision problems. This issue is particularly prominent in the following typical structural scenarios:

[0004] 1. Adjacent Windows on Curved Facades: Commercial office buildings and other structures often feature curved curtain wall structures for aesthetic purposes. These curved locations require two adjacent outward-opening windows to meet fire and smoke extraction requirements. Due to the spatial constraints of the curved structure, the installation trajectories of adjacent windows are distributed in an arc, and the spacing is limited by the structure, making it difficult to increase. Furthermore, the opening trajectories of both windows extend outward along the tangent of the arc. When the windows open to 25°-35°, the outer corners of the window sashes protrude along the arc, encroaching on the rotation range of adjacent windows. This can lead to frame collisions, handle scrapes, and in severe cases, window sash deformation and glass loosening, affecting normal opening and closing and fire and smoke extraction functions. Existing solutions often involve adding vertical struts in the middle to increase the spacing, which can avoid collisions but disrupts the smoothness and overall aesthetics of the curved facade.

[0005] 2. Recessed Walls with Dense Window Groups: Some buildings feature recessed walls to optimize interior lighting or aesthetic design, with a recess depth typically reaching 50-80cm. If multiple adjacent outward-opening windows are to be installed on such walls, the narrow recessed space restricts the outward fan-shaped trajectory of the windows when they open, causing overlapping opening ranges between adjacent windows. When the recess depth is too deep (over 60cm) and the window spacing is less than 40cm, if the window opening angle exceeds 30°, the outer corner of the window sash will directly encroach on the rotation area of ​​adjacent windows, causing a chain reaction of interference between multiple windows. This not only prevents them from opening to their maximum ventilation angle but may also damage the hardware due to collisions.

[0006] 3. Adjacent Windows in Corner Curtain Walls: Adjacent outward-opening windows at building corners (such as 90° right angles or 120° obtuse angle curtain wall corners) have "diagonally intersecting" opening trajectories due to their angular installation orientation. Taking a 90° corner as an example, the windows on both sides open in different directions, and their fan-shaped opening trajectories overlap in the public space outside the corner. When the opening angle reaches 20°-30°, the outer corners of the window sashes will collide with each other. If forced open, it may cause deformation of the window frame or breakage of the glass. Especially in high-rise buildings, such collisions pose a safety hazard.

[0007] 4. Ultra-narrow spacing functional window groups: In areas such as hospital corridors and office building cores, fire prevention and smoke exhaust regulations require densely arranged outward-opening windows in limited spaces, with the spacing between adjacent windows often compressed to 30-50cm. Because the spacing is less than the maximum extension distance of the window sash when opened (usually 30-40cm), even if the wall has no concave or curved structure, when the window is opened to more than 40°, the outer corner of the window sash will encroach on the rotation range of the adjacent window, causing the two windows to be unable to be fully opened at the same time, affecting emergency ventilation and smoke exhaust efficiency.

[0008] The core problem in the above scenario is that the rotational opening trajectory of outward-opening windows extends outward in a fan shape. However, special structural conditions such as curved structures, concave spaces, corner layouts, and ultra-narrow spacing result in insufficient safety clearance between adjacent windows, causing their opening trajectories to intersect. Existing technologies, whether by adding mullions, reducing the opening angle, or increasing the installation spacing, all suffer from drawbacks such as damaging the building's appearance, reducing functionality, or being unable to be implemented due to space limitations. Therefore, there is an urgent need for a glass curtain wall window that does not require changes to the installation spacing, adapts to various special structural positions, and can avoid opening interference by optimizing the window sash's own structure, thus addressing the pain points of existing technologies. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this invention proposes a glass curtain wall window.

[0010] To achieve the above objectives, the present invention provides the following technical solution: A glass curtain wall window, installed within a mounting frame, includes a window frame disposed within the mounting frame and a glass panel fixedly disposed within the window frame. The top of the window frame is rotatably connected to the mounting frame. The window frame has an inverted trapezoidal structure that is wider at the top and narrower at the bottom. Vertical plates are symmetrically arranged on both sides of the window frame, and the vertical plates are sealed to the corresponding side edges of the window frame through a sealing elastic membrane. A flexible metal connecting piece is fixedly connected to the upper end of the vertical plate, and the side of the flexible metal connecting piece away from the vertical plate is fixedly connected to the side wall of the window frame. A connecting rod is fixedly connected to the side wall of the vertical plate near the lower end. A matching through hole is provided on the side wall of the window frame corresponding to the connecting rod. The end of the connecting rod away from the vertical plate passes through the through hole and extends into the interior of the window frame, with the connecting rod and the through hole fitting together. A long rod is connected to the end of the connecting rod inside the window frame, and the long rod is further away from the connecting rod. One end of the connecting rod is fixedly connected to a fixed sleeve, and a rotating rod is slidably connected inside the fixed sleeve. The outer wall of the rotating rod has an annular guide groove, and the inner side wall of the fixed sleeve has a guide block, which is slidably connected in the annular guide groove. The end of the rotating rod away from the fixed sleeve is fixedly connected to a rotating shaft. A support block is fixedly installed on the inner wall of the window frame corresponding to the rotating shaft, and the rotating shaft is rotatably connected to the support block. A driving assembly is installed on the window frame, and the driving assembly is connected to the rotating shaft for transmission. When the window is opened, the driving assembly drives the rotating shaft to rotate, which drives the rotating rod to rotate synchronously. The rotating rod drives the fixed sleeve to move horizontally along the axis of the rotating rod through the sliding cooperation between the guide block and the annular guide groove. The moving fixed sleeve is transmitted sequentially through the long rod and the connecting rod, pulling the lower end of the vertical plate to shift towards the window frame. The sealing elastic membrane is compressed and undergoes elastic deformation, so that the window sash composed of the window frame, vertical plate and glass plate forms an inverted trapezoidal structure that is wider at the top and narrower at the bottom and fits the window frame.

[0011] Preferably, the drive assembly includes a control rod that rotates through the window frame, with one end extending to the outside of the window frame and the other end extending to the inside of the window frame; a second gear is fixedly sleeved on the rod segment inside the window frame; the drive assembly also includes a shaft that rotates to the inner wall of the window frame, with a first gear fixedly sleeved on the outer wall of the shaft, the first gear meshing with the second gear for transmission, and a worm gear fixedly sleeved on the outer wall of the shaft; a worm wheel is fixedly connected to the end of the rotating shaft away from the rotating rod, and the worm wheel meshing with the worm gear constitutes a worm gear transmission structure.

[0012] Preferably, a handle is fixedly connected to one end of the control rod extending to the window frame.

[0013] Preferably, a first protrusion is provided on the section of the control rod extending outside the window frame, and a second protrusion is provided on the mounting bracket corresponding to the first protrusion; in the locked state, the first protrusion and the second protrusion abut against each other and limit each other, and the window frame and the mounting bracket are locked together; when the control rod is rotated, the first protrusion rotates synchronously with the control rod and is displaced and separated from the second protrusion, releasing the locked state and allowing the window frame to open outward.

[0014] Preferably, a first long shaft is rotatably connected to the inner wall of the bottom of the mounting bracket, and a plurality of first thread pulleys are fixedly connected to the outer wall of the first long shaft. A first protective wire is wound on the first thread pulley. A clearance groove is provided on the bottom side wall of the window frame, and a first magnet frame is fixedly connected in the clearance groove. One end of the first protective wire is fixed to the first thread pulley, and the other end passes through the mounting bracket and is connected to a second magnet frame. The second magnet frame is magnetically fixed to the first magnet frame corresponding to the bottom of the window frame. A first spring is sleeved on the outer wall of the first long shaft, and one end of the first spring is fixedly connected to the first long shaft, and the other end of the first spring is fixedly connected to the inner wall of the mounting bracket.

[0015] Preferably, the inner wall of the mounting frame has a rectangular groove corresponding to each first spool, and a fixing block is slidably connected to the inner wall of the rectangular groove. A threaded rod is fixedly connected to the upper surface of the fixing block, and a rotating sleeve is threaded on the outer wall of the threaded rod. One end of the rotating sleeve passes through the mounting frame and extends to the outside of the mounting frame. The rotating sleeve is rotatably connected to the mounting frame. A third gear is fixedly connected to one end of the rotating sleeve located outside the mounting frame. A fourth gear is provided on the control rod corresponding to the third gear. The third gear and the fourth gear mesh with each other.

[0016] Preferably, clearance grooves are also provided on the left and right side walls of the window frame, and a first magnet frame is fixedly connected in the clearance grooves; a second long shaft is fixedly connected to the inner walls of the left and right sides of the mounting bracket, and a second thread wheel is rotatably sleeved on the outer wall of the second long shaft. A cavity is provided inside the second thread wheel, and a second spring is provided in the cavity. One end of the second spring is fixedly connected to the second long shaft, and the other end is fixedly connected to the second thread wheel. A second protective wire is wound around the outer wall of the second thread wheel. One end of the second protective wire is fixedly connected to the second thread wheel, and the other end passes through the mounting bracket and is connected and fixed to the second magnet frame. The second magnet frame is magnetically fixed to the corresponding first magnet frames on the left and right sides of the window frame.

[0017] Preferably, it also includes a sealing structure, which includes an elastic sealing airbag disposed within the mounting frame. The elastic sealing airbag is U-shaped and surrounds the outer sides of the two vertical plates, and is fixedly connected to the outer walls of the two vertical plates. When the window is closed, the elastic sealing airbag adapts to the inverted trapezoidal structure of the window frame and the parallel arrangement of the vertical plates, and is in a naturally unfolded state. Its outer wall is tightly fitted with the inner wall of the mounting frame to achieve a seal. When the window is opened, as the lower end of the vertical plate shifts towards the window frame, the distance between the lower parts of the two vertical plates increases, making the surrounding space larger. The lower part of the elastic sealing airbag naturally contracts and deflates due to the loss of the squeezing constraint of the mounting frame, and its outer wall disengages from the inner wall of the mounting frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention, through the coordinated use of a resilient metal connecting piece, a vertical plate, and a driving assembly, allows the driving assembly to drive a worm gear when the window is opened, in addition to unlocking. The rotating worm gear drives a rotating shaft and a rotating rod to rotate. The rotating rod, through a guide block and a ring guide groove, moves a fixed sleeve. The moving fixed sleeve, through a long rod and a connecting rod, causes one end of the vertical plate to shift towards the window frame. After the vertical plate shifts, the entire window forms a trapezoidal shape, wider at the top and narrower at the bottom, similar to the window frame. When the window is opened, the outer corners of the window sash become smaller, thus preventing the outer corners of the window sash from easily encroaching on the rotation range of adjacent windows.

[0020] This invention, by setting up a worm gear and shaft for coordinated use, when the control lever is rotated, the rotating control lever drives the first protrusion to rotate, causing the first protrusion and the second protrusion to misalign, thus completing the unlocking. When the control lever rotates, it can also drive the second gear to rotate, and the rotating second gear drives the first gear, shaft and worm gear to rotate. The rotating worm gear drives the worm wheel to rotate. This worm wheel driving and unlocking can be completed in one step, thus facilitating the use of this device.

[0021] This invention, by setting up an elastic sealing airbag, can increase the sealing between the mounting bracket and the window. When the vertical plate is offset towards the window frame to open the window, the lower part of the elastic sealing airbag loses the compression of the mounting bracket, and the inflated elastic sealing airbag will shrink and then deflate. In this way, the outer wall of the elastic sealing airbag can detach from the inner wall of the mounting bracket, so as to avoid the elastic sealing airbag from sliding friction with the inner wall of the mounting bracket and being damaged when the window is opened.

[0022] This invention allows for window opening when there are no pets indoors and the first and second protective wires are not required. The window can be opened by reversing the control lever. Reversing the lever rotates the fourth gear, which in turn rotates the third gear, which in turn rotates the rotating sleeve. The rotating sleeve causes the threaded rod and the fixing block to move downwards. The lowered fixing block presses against the outer wall of the first threaded wheel, preventing the first protective wire and the second magnet frame from being pulled apart when the window is opened. Thus, turning the control lever forward allows the protective wire to be pulled out for protection, while reversing the lever allows the window to be opened directly. The operation is simple and convenient. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Please see Figures 1 to 11A glass curtain wall window, installed within a mounting frame 1, includes a window frame 3 housed within the mounting frame 1 and a glass panel 2 fixedly installed within the window frame 3. The top of the window frame 3 is rotatably connected to the mounting frame 1; specifically, the rotatable connection can be a damping pivot or hinge, or other commonly used connectors by those skilled in the art. The window frame 3 has an inverted trapezoidal structure, wider at the top and narrower at the bottom. Vertical plates 4 are symmetrically arranged on both sides of the window frame 3, and the vertical plates 4 are sealed to the corresponding side edges of the window frame 3 via a sealing elastic membrane 5. A flexible metal connecting piece 6 is fixedly connected to the upper end of the vertical plate 4, and the side of the flexible metal connecting piece 6 away from the vertical plate 4 is fixedly connected to the side wall of the window frame 3. A connecting rod 7 is fixedly connected to the side wall of the vertical plate 4 near its lower end. A matching through hole 8 is provided on the side wall of the window frame 3 corresponding to the connecting rod 7. The end of the connecting rod 7 away from the vertical plate 4 passes through the through hole 8 and extends into the interior of the window frame 3, with a clearance fit between the connecting rod 7 and the through hole 8. 7 is located inside the window frame 3 and is connected to a long rod 9. The end of the long rod 9 away from the connecting rod 7 is fixedly connected to a fixed sleeve 10. A rotating rod 11 is slidably sleeved inside the fixed sleeve 10. A ring guide groove 12 is opened on the outer wall of the rotating rod 11. A guide block 13 is provided on the inner side wall of the fixed sleeve 10. The guide block 13 is slidably connected in the ring guide groove 12. A rotating shaft 14 is fixedly connected to the end of the rotating rod 11 away from the fixed sleeve 10. A support block 16 is fixedly set on the inner wall of the window frame 3 corresponding to the rotating shaft 14. The rotating shaft 14 is rotatably connected to the support block 16. A driving assembly is provided on the window frame (3). The driving assembly is connected to the rotating shaft 14 in a transmission manner.

[0037] As can be seen from the above structure, by setting up the tough metal connecting piece 6, the vertical plate 4 and the drive component and other structures to work together, when the window is opened, the drive component drives the rotating shaft 14 to rotate, which drives the rotating rod 11 to rotate synchronously. The rotating rod 11 drives the fixed sleeve 10 to move horizontally along the axis of the rotating rod 11 through the sliding cooperation of the guide block 13 and the ring guide groove 12. The moving fixed sleeve 10 is transmitted sequentially through the long rod 9 and the connecting rod 7, pulling the lower end of the vertical plate 4 to shift towards the window frame 3. The sealing elastic membrane 5 is compressed and undergoes elastic deformation, so that the window sash composed of the window frame 3, the vertical plate 4 and the glass plate 2 forms an inverted trapezoidal structure that is wider at the top and narrower at the bottom and fits the window frame 3. When the window is pushed open, the outer corner of the window sash becomes smaller, which can avoid the problem that the outer corner of the window sash can easily intrude into the rotation range of the adjacent window.

[0038] Furthermore, the drive assembly includes a control rod 21 that rotates through the window frame 3, with one end of the control rod 21 extending to the outside of the window frame 3 and the other end extending to the inside of the window frame 3; a second gear 20 is fixedly sleeved on the rod segment of the control rod 21 located inside the window frame 3; the drive assembly also includes a shaft 18 that is rotatably connected to the inner wall of the window frame 3, with a first gear 19 fixedly sleeved on the outer wall of the shaft 18, the first gear 19 meshing with the second gear 20 for transmission, and a worm gear 17 fixedly sleeved on the outer wall of the shaft 18; a worm wheel 15 is fixedly connected to the end of the rotating shaft 14 away from the rotating rod 11, and the worm wheel 15 meshing with the worm gear 17 to form a worm gear transmission structure; when the control rod 21 rotates, the rotating control rod 21 drives the second gear 20 to rotate, the rotating second gear 20 drives the first gear 19, the shaft 18 and the worm gear 17 to rotate, and the rotating worm gear 17 drives the worm wheel 15 to rotate.

[0039] Furthermore, a handle 40 is fixedly connected to one end of the control lever 21 that extends to the window frame 3; by providing the handle 40, the control lever 21 can be rotated via the handle 40.

[0040] Furthermore, a first protrusion 22 is provided on the section of the control lever 21 extending outside the window frame 3, and a second protrusion 23 is provided on the mounting bracket 1 corresponding to the first protrusion 22; in the locked state, the first protrusion 22 and the second protrusion 23 abut against each other and limit each other, and the window frame 3 and the mounting bracket 1 are locked together; when the control lever 21 is rotated, the first protrusion 22 rotates synchronously with the control lever 21 and is displaced and separated from the second protrusion 23, releasing the locked state, so that the window frame 3 can be opened outward.

[0041] Furthermore, a first long shaft 25 is rotatably connected to the inner wall of the bottom of the mounting bracket 1, and multiple first thread pulleys 26 are fixedly connected to the outer wall of the first long shaft 25. A first protective wire 27 is wound on the first thread pulley 26. A clearance groove is opened on the bottom side wall of the window frame 3, and a first magnetic frame 28 is fixedly connected in the clearance groove. One end of the first protective wire 27 is fixed to the first thread pulley 26, and the other end passes through the mounting bracket 1 and is connected to a second magnetic frame 29. The second magnetic frame 29 is magnetically fixed to the corresponding first magnetic frame 28 at the bottom of the window frame 3. A first spring 30 is sleeved on the outer wall of the first long shaft 25, and one end of the first spring 30 is fixedly connected to the first long shaft 25. The other end of the first spring 30 is fixedly connected to the inner wall of the mounting bracket 1. By setting the first protective wire 27, the first magnetic frame 28, and the second magnetic frame 29 in cooperation, after the window is opened, the first protective wire 27 can be pulled open to block the opening below the window frame 3 and the mounting bracket 1, thus preventing pets from falling through the window opening.

[0042] Furthermore, clearance grooves are also provided on the left and right side walls of the window frame 3, and a first magnetic frame 28 is fixedly connected in the clearance grooves; a second long shaft 36 is fixedly connected to the inner walls of the left and right sides of the mounting bracket 1, and a second thread wheel 37 is rotatably sleeved on the outer wall of the second long shaft 36. A cavity is provided inside the second thread wheel 37, and a second spring 38 is provided in the cavity. One end of the second spring 38 is fixedly connected to the second long shaft 36, and the other end is fixedly connected to the second thread wheel 37. A second protective wire 39 is wound around the outer wall of the second thread wheel 37. One end of the second protective wire 39 is fixedly connected to the second thread wheel 37, and the other end passes through the mounting bracket 1 and is connected and fixed to the second magnetic frame 29. The second magnetic frame 29 is magnetically fixed to the corresponding first magnetic frames 28 on the left and right sides of the window frame 3. By setting the second long shaft 36 and the second protective wire 39 to work together, after the window is opened, the second protective wire 39 can be pulled open to block the opening of the side wall between the window frame 3 and the mounting bracket 1, so as to prevent pets from falling through the window opening.

[0043] Furthermore, the inner wall of the mounting frame 1 has a rectangular groove corresponding to each first threaded reel 26, and a fixing block 32 is slidably connected to the inner wall of the rectangular groove. A threaded rod 32 is fixedly connected to the upper surface of the fixing block 31, and a rotating sleeve 33 is threadedly fitted onto the outer wall of the threaded rod 32. One end of the rotating sleeve 33 passes through the mounting frame 1 and extends to the outside of the mounting frame 1. The rotating sleeve 33 is rotatably connected to the mounting frame 1. A third gear 34 is fixedly connected to one end of the rotating sleeve 33 located outside the mounting frame 1. A fourth gear 35 is provided on the control lever 21 corresponding to the third gear 34. The third gear 34 and the fourth gear 35 mesh with each other. By setting the fixing block 31 and the rotating sleeve 33 to work together, when there are no pets in the room and the protection of the first protective wire 27 and the second protective wire 39 is not needed, the window can be opened by reversing the control lever 21 through the handle 40. When the control lever 21 is reversed, the reversed control lever 21 drives the fourth gear 35 to rotate. The rotating fourth gear 35 drives the third gear 34 to rotate. The rotating third gear 34 drives the rotating sleeve 33 to rotate. 3. Rotation: The rotating sleeve 33 drives the threaded rod 32 and the fixing block 31 to move downwards. The moving fixing block 31 presses against the outer wall of the corresponding first thread pulley 26 on the lower side. After the fixing block 31 moves down and presses against one of the first thread pulleys 26, all the first protective wires 27 and second protective wires 39 cannot be pulled apart. This is because all the first thread pulleys 26 are fixedly connected to the same first long shaft 25 and are a synchronously rotating integral structure. When the fixing block 31 presses against any one of the first thread pulleys 26, it will restrict the rotation of the entire first long shaft 25, thus preventing all the first thread pulleys 26 from rotating to release the first protective wires 27 wound on them. On the other hand, the second magnet frame 29 connecting the first protective wires 27 and the second protective wires 39 is an integrally formed structure. When the first protective wire 27 at the bottom cannot be pulled out because the first thread pulley 26 is locked, the integral second magnet frame 29 will be restricted in its displacement, thus preventing the second protective wires 39 on the left and right sides from being released synchronously from the second thread pulley 37, ultimately achieving the effect that all protective wires cannot be pulled apart.

[0044] Furthermore, it also includes a sealing structure, which includes an elastic sealing airbag 24 disposed within the mounting frame 1. The elastic sealing airbag 24 is U-shaped and surrounds the outer sides of the two vertical plates 4, and is fixedly connected to the outer side walls of the two vertical plates 4. When the window is closed, the elastic sealing airbag 24 adapts to the inverted trapezoidal structure of the window frame 3 and the parallel arrangement of the vertical plates 4, and is in a naturally unfolded state. Its outer wall is tightly fitted with the inner wall of the mounting frame 1 to achieve a seal. By setting the elastic sealing airbag 24, the sealing between the mounting frame 1 and the window can be increased. When the window is opened by shifting one end of the vertical plate 4 towards the window frame 3, the lower part of the elastic sealing airbag 24 loses the compression of the mounting frame 1, and the expanded elastic sealing airbag 24 will shrink and then deflate. In this way, the outer wall of the elastic sealing airbag 24 can detach from the inner wall of the mounting frame 1, so as to avoid the elastic sealing airbag 24 from sliding friction with the inner wall of the mounting frame 1 and damaging the elastic sealing airbag 24 when the window is opened.

[0045] As another embodiment of the protection mode control for controlling the first protective wire 27 and the second protective wire 39, in this embodiment, the second magnet frame 29 adopts an electromagnet structure, and a magnetic attraction control switch is provided on the outside of the mounting bracket 1. The magnetic attraction control switch is electrically connected to the electromagnetic coil of the second magnet frame 29. In the protection mode, the magnetic attraction control switch is closed, the second magnet frame 29 is energized and generates magnetism, and is magnetically attracted and fixed to the first magnet frame 28 on the window frame 3. When the window is opened, the first protective wire 27 and the second protective wire 39 are pulled out to form protection. In the non-protection mode, the magnetic attraction control switch 42 is disconnected, the second magnet frame 29 is de-energized and loses magnetism, and is detached from the first magnet frame 28. When the window is opened, the first protective wire 27 and the second protective wire 39 remain in a wound state and do not move and unfold with the window frame 3.

[0046] In this invention, during use, by rotating the control lever 21 via the handle 40, the rotating control lever 21 drives the first protrusion 22 to rotate, causing the first protrusion 22 and the second protrusion 23 to be misaligned, thus pushing the window frame 3 to open. When the control lever 21 rotates, it also drives the second gear 20 to rotate. The rotating second gear 20 drives the first gear 19, the shaft 18, and the worm gear 17 to rotate. The rotating worm gear 17 drives the worm wheel 15 to rotate. When the worm wheel 15 rotates, it drives the rotating shaft 14 and the rotating rod 11 to rotate. The rotating rod 11, through the guide block 13 and the ring guide groove 12, drives the fixed sleeve 10 to move. The moving fixed sleeve 10, through the long rod 9 and the connecting rod 7, drives one end of the vertical plate 4 to shift towards the window frame 3. After the vertical plate 4 shifts, the window as a whole will form a trapezoid that is wider at the top and narrower at the bottom, just like the window frame 3. When the window is pushed open, the outer corner of the window sash becomes smaller, thus avoiding the problem of the outer corner of the window sash easily encroaching on the rotation range of adjacent windows.

[0047] When one end of the vertical plate 4 shifts towards the window frame 3, the elastic sealing airbag 24 loses the compression from the mounting bracket 1, causing the inflated elastic sealing airbag 24 to shrink and deflate. This allows the outer wall of the elastic sealing airbag 24 to detach from the inner wall of the mounting bracket 1, preventing sliding friction and damage to the elastic sealing airbag 24 when the window is opened. Closing the window is achieved by reversing the steps.

[0048] This invention addresses the collision problem caused by the intersecting opening trajectories of adjacent outward-opening windows in special structural scenarios such as curved facades, recessed walls, corner curtain walls, and ultra-narrow spacing. It eliminates the need for methods that damage the building's appearance, such as adding mullions or widening installation spacing. By automatically forming an inverted trapezoidal structure that is wider at the top and narrower at the bottom when the window sash opens, it effectively reduces the protrusion range of the window sash's outer corners, fundamentally avoiding interference with the rotation range of adjacent windows. This ensures both the normal opening function and fire prevention and smoke extraction efficiency of the windows, while maintaining the smoothness and aesthetics of the building facade, perfectly balancing functional requirements and design harmony.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
