[0002] In the field of building doors and windows, casement windows, as a common window type, have always attracted much attention regarding the method of fixing their frames to the walls. Existing patent document "CN 206220755 U" discloses a window with an easily fixed frame. Although it uses screws passing through fixing holes on both sides of a fixing plate to connect the window frame to the wall with mounting fasteners, and two screws are placed on the indoor and outdoor sides of the window frame respectively, the outdoor screws are exposed to harsh natural environments for a long time, including sun, rain, and wind erosion, making them prone to oxidation and corrosion. Over time, the mechanical strength of the screws decreases significantly, affecting not only the firmness of the window frame fixation but also potentially causing the window frame to loosen and deform, posing a safety hazard to the building. Furthermore, the installation of outdoor screws requires workers to operate at heights outdoors or use complex climbing equipment, increasing the difficulty and danger of installation.

[0047] Reference Figures 1-13 This embodiment provides a casement window, including a window frame, a light-transmitting component, and a connecting component 3;

[0048] The window frame includes a frame assembly 10, which includes at least two adjacent horizontal frames 101 and vertical frames 102, and the horizontal frames 101 and vertical frames 102 together form an accommodating space.

[0049] The light-collecting component is disposed within the accommodating space;

[0050] The connecting component 3 is detachably connected to the longitudinal frame 102. The connecting component 3 is used to connect the longitudinal frame 102 to the wall via the first fastener 4, and the first fastener 4 is located on the side of the longitudinal frame 102 facing the interior.

[0051] In the above embodiment, the casement window includes a window frame, a light-transmitting component, and a connecting component 3. The window frame is the frame structure of the casement window, and its frame component 10 consists of two horizontal frames 101 and two vertical frames 102. The horizontal frames 101 are arranged horizontally, and the vertical frames 102 are perpendicular to the horizontal frames 101. The two are arranged adjacent to each other and enclose an accommodating space. This accommodating space is used to install components such as the light-transmitting component, providing structural support for the entire window. The light-transmitting component is installed in the accommodating space of the window frame, and its function is to realize the light-transmitting function of the window, while also having a ventilation function. In this design, the glass in the daylighting component is preferably double-glazed glass, and the window frame is made of thermally broken aluminum profile, but other thermal insulation materials such as PVC or wood can also be used. The excellent thermal insulation performance of the double-glazed glass and thermally broken aluminum profile effectively blocks heat exchange between the interior and exterior, improving the building's energy efficiency. Multiple connecting components 3 are included, and they are detachably connected to the longitudinal frame 102. These components are crucial for connecting the window frame to the wall. The longitudinal frame 102 is fixed to the wall by a first fixing member 4, located on the interior side of the longitudinal frame 102. The first fixing member 4 is preferably an expansion screw. During installation, the daylighting component is first placed within the receiving space of the window frame. Then, one end of the connecting component 3 is detachably connected to the longitudinal frame 102. Finally, expansion screws are used to pass through the corresponding part of the connecting component 3 on the interior side to fix the longitudinal frame 102 to the wall. Therefore, under the premise of ensuring the connection strength between the window frame and the wall, the window frame is connected to the wall only through the first fixing part 4 inside the wall and the connecting component 3. This completely avoids the situation where the outdoor screws are exposed to sun, rain and wind and sand erosion in the existing technology, reduces the risk of window frame loosening due to corrosion of the fixing parts, ensures a long-term stable connection between the window frame and the wall, and at the same time, workers no longer need to carry out complicated and dangerous outdoor high-altitude operations to install the fixing parts, effectively protecting the personal safety of construction workers.

[0052] Reference Figures 1-12 In one embodiment, the connecting component 3 includes a snap-fit ​​portion 30, a vertical portion 31, and an extension portion 32. The snap-fit ​​portion 30 is snap-fitted onto the longitudinal frame 102. The vertical portion 31 is disposed on the side of the snap-fit ​​portion 30 near the interior and extends in a direction perpendicular to the snap-fit ​​portion 30. The extension portion 32 is disposed on the side of the vertical portion 31 away from the snap-fit ​​portion 30 and extends in a direction perpendicular to the vertical portion 31. The first fastener 4 is connected to the extension portion 32 via a connecting gasket 33.

[0053] In the above embodiment, the connecting component 3 includes a snap-fit ​​portion 30, a vertical portion 31, and an extension portion 32. The main function of the snap-fit ​​portion 30 is to achieve a snap-fit ​​connection with the longitudinal frame 102, and it can be tightly engaged with the longitudinal frame 102. The vertical portion 31 is located at the end of the snap-fit ​​portion 30 closer to the interior, and the vertical portion 31 extends a certain distance in a direction perpendicular to the snap-fit ​​portion 30, such that the length of the vertical portion 31 is greater than the depth of the slot used to engage the snap-fit ​​portion 30. The extension portion 32 is located on the side of the vertical portion 31 away from the snap-fit ​​portion 30, and extends in a direction perpendicular to the vertical portion 31. The extension 32 extends into the interior and provides an installation position for the first fixing member 4. It is connected to the first fixing member 4 through the connecting gasket 33, and the longitudinal frame 102 is fixed to the wall. The connecting gasket 33 is located between the wall and the extension 32 to ensure that the expansion screw will not damage the extension 32 and the wall when tightened. In the overall structure, the buckle 30 is tightly connected to the longitudinal frame 102, and the vertical part 31 and the extension 32 are arranged vertically in sequence to form a stable connection structure, which together realizes the function of firmly connecting the longitudinal frame 102 to the wall.

[0054] Reference Figures 1-10 In one embodiment, the window frame further includes a mast assembly 11, which includes at least two first longitudinal masts 110 and a transverse mast 111. The first longitudinal masts 110 are connected between two oppositely arranged transverse side frames 101, and the transverse masts 111 are connected between two oppositely arranged longitudinal side frames 102. The first longitudinal masts 110 and the transverse masts 111 are arranged perpendicularly to each other.

[0055] The first longitudinal center mullion 110, the transverse center mullion 111, the transverse frame 101, and the longitudinal frame 102 together form a first accommodating space and a second accommodating space, and a third accommodating space, a fourth accommodating space, and a fifth accommodating space are symmetrically arranged on both sides of the first accommodating space, respectively. The first accommodating space and the second accommodating space are arranged vertically, and the fourth accommodating space is located between the third accommodating space and the fifth accommodating space.

[0056] In the above embodiment, the window frame further includes a mullion assembly 11, which includes a first longitudinal mullion 110 and a transverse mullion 111. There are at least two first longitudinal mullions 110 and at least two transverse mullions 111. The first longitudinal mullion 110 is a vertical member in the mullion assembly 11, connected between two oppositely arranged transverse side frames 101, and its direction is consistent with the longitudinal side frame 102. The transverse mullion 111 is a transverse member in the mullion assembly 11, connected between two oppositely arranged longitudinal side frames 102, and arranged perpendicularly to the first longitudinal mullion 110, together constructing the internal spatial structure of the window frame. The first longitudinal mullion 110, the transverse mullion 111, the transverse side frames 101, and the longitudinal side frames 102 are interconnected and enclosed to form multiple different accommodating spaces, which is the entire accommodating space used to place the lighting components. The first accommodating space and the second... The two accommodating spaces are arranged vertically, with the same width, occupying the main space area in the entire window frame structure and can be used to install larger lighting components. The third accommodating space consists of two symmetrically arranged on both sides of the first accommodating space, and the fifth accommodating space consists of two symmetrically arranged on both sides of the second accommodating space. The fourth accommodating space consists of two located between the third and fifth accommodating spaces. All three spaces have the same width, which is half the width of the first accommodating space. The sum of the lengths from the bottom of the fourth accommodating space to the top of the third accommodating space is equal to the length of the first accommodating space, and the length of the fifth accommodating space is equal to that of the second accommodating space. This allows for a reasonable division of the internal space of the window frame, enabling flexible arrangement of various parts of the lighting components according to different needs, improving space utilization, while ensuring the symmetry and stability of the window frame structure, making the overall appearance of the window more beautiful and harmonious.

[0057] Reference Figures 1-10 In one embodiment, the end of the first longitudinal mullion 110 passes through the transverse frame 101, and an installation member 112 is fixedly connected to the end of the first longitudinal mullion 110. The installation member 112 connects the first longitudinal mullion 110 to the wall through a second fastener 113.

[0058] In the above embodiment, the end of the first longitudinal mullion 110 passes through the transverse frame 101, and the two form a vertically intersecting connection relationship and are fixed by welding. The end of the first longitudinal mullion 110 is used to install the mounting component 112, which provides a transition structure for connecting the first longitudinal mullion 110 and the wall. Mounting component 112 is fitted into the opening at the end of the first longitudinal mullion 110 and is firmly connected to the first longitudinal mullion 110 by glue or welding to ensure the reliability of the connection. The second fixing component 113 is a key connector for connecting the first longitudinal mullion 110 to the wall. Its position can be on the side of the wall closer to the interior, or it can be inside or outside the wall. The second fixing component 113 is preferably an expansion bolt. The expansion bolt passes through the mounting component 112. After tightening, its expanded part tightly engages with the wall, thereby fixing the first longitudinal mullion 110 and the transverse frame 101 welded to it to the wall. Each first longitudinal mullion 110 has a mounting component 112 and a corresponding expansion bolt at both ends, which effectively ensures the stability of the window frame fixed to the wall, so that the window frame can be evenly stressed and is not prone to tilting or deformation.

[0059] Reference Figures 1-10 In one embodiment, the light-collecting component includes a fixed sash module and two first window sashes 21. The fixed sash module includes a first fixed sash 201, a second fixed sash 202, two third fixed sashes 203, and a fourth fixed sash 204. The two first window sashes 21 are respectively disposed in the two third accommodating spaces. One side of the first window sash 21 is rotatably connected to the longitudinal frame 102, and the opposite side is snap-fitted to the first longitudinal mullion 110. The first fixed sash 201 is fixedly connected in the first accommodating space, the second fixed sash 202 is fixedly connected in the second accommodating space, the two third fixed sashes 203 are fixedly connected in the fourth accommodating space, and the two fourth fixed sashes 204 are fixedly connected in the fifth accommodating space.

[0060] In the above embodiments, the lighting assembly includes a fixed sash module and two first window sashes 21.

These fixed sashes are all insulated glass, and they are tightly connected to the corresponding accommodating spaces of the window frame through a fixed connection method (such as adhesive bonding or slot fixing, etc.). Their main function is to provide a large lighting area, and because they are fixed, they can ensure the stability of the window structure; A window sash 21 consists of a window sash frame and a window sash body. The window sash body is preferably made of insulated glass. The window sash frame is connected to the side of the third accommodating space. One side is rotatably connected to the longitudinal frame 102 to realize the opening and closing function of the window sash. The other side is snapped to the first longitudinal mullion 110 to ensure that the window sash is stable when closed. This connection method not only facilitates the user's operation of the window sash for ventilation, but also ensures that the window sash and the window frame fit tightly when closed, guaranteeing good sealing performance. By rationally distributing the fixed sash module and the first window sash 21 in different accommodating spaces of the window frame, the functions of lighting, ventilation and aesthetics are realized together, meeting the various needs of the building for windows.

[0061] Reference Figures 1-8 In one embodiment, the window frame is provided with a receiving groove 12 for accommodating the light-transmitting component, and a glass pad 13 is provided between the end of the light-transmitting component and the bottom of the receiving groove 12. An interlayer glass bonding strip 14 is provided on the side of the light-transmitting component adjacent to the glass pad 13, and the interlayer glass bonding strip 14 is snapped onto the side of the receiving groove 12.

[0062] In the above embodiment, the receiving groove 12 is set on the window frame, and its shape and size are adapted to the lighting component to accurately accommodate the lighting component and ensure that the installation position of the lighting component in the window frame is accurate and stable. The glass gasket 13 is placed between the end of the lighting component and the bottom of the receiving groove 12, and is preferably placed at the bottom of the first fixed sash 201, the second fixed sash 202, the third fixed sash 203 and the fourth fixed sash 204. The glass gasket 13 plays the role of buffering, shock absorption and filling gaps. The interlayer glass sealing strip 14 is located on the side of the lighting component adjacent to the glass gasket 13, and is fixed to the side of the receiving groove 12 by a snap-fit ​​connection. The interlayer glass sealing strip 14 further fixes the lighting component to prevent it from shifting in the horizontal direction, ensuring the tightness of the connection between the lighting component and the window frame. It also plays a certain sealing role to prevent external dust, moisture and other substances from entering, so that the lighting component and the window frame form a whole and ensure the airtightness and stability of the window.

[0063] Reference Figure 11In one embodiment, the window frame further includes a second longitudinal mullion 15, which is connected between two oppositely arranged horizontal frame edges 101. The second longitudinal mullion 15, the horizontal frame edges 101, and the longitudinal frame edges 102 together form two sixth accommodating spaces symmetrical about the second longitudinal mullion 15. The light-transmitting component includes two second window sashes 22, which are respectively disposed in the two sixth accommodating spaces. One side of the second window sash 22 is rotatably connected to the longitudinal frame edge 102, and the opposite side is snap-fitted to the second longitudinal mullion 15.

[0064] In the above embodiment, the window frame also includes a second longitudinal mullion 15, which is a vertical support structure component of the window frame. It is connected between two opposite horizontal frame sides 101 and together with the vertical frame side 102, it forms the window frame frame. The second longitudinal mullion 15, the horizontal frame side 101 and the vertical frame side 102 together form two sixth accommodating spaces symmetrical about the second longitudinal mullion 15, providing an installation position for the second window sash 22 in the lighting assembly. The lighting assembly includes two second window sashes 22, which are composed of a window sash frame and a window sash body with double glazing. The window sash frame is connected to the side of the sixth accommodating space.
