Abstract

This invention discloses a wind-resistant, silent load-bearing component and a concealed-sash sliding window for sea views, relating to the field of door and window technology. The silent load-bearing component includes: a sliding window sash with upper and lower horizontal sections; a fixed frame with an upper sliding frame and a lower sliding frame; and at least one layered elastic component, comprising: multiple stacked arc-shaped spring sheets; a stop block; a telescopic outer sleeve; and a telescopic rod. When the sliding window sash is subjected to sea breeze pulsations from the indoor to the outdoor direction, the stop block is pressed against the upper sliding frame and / or the lower sliding frame, causing the arc-shaped spring sheets to be compressed and tend to straighten.

Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to a wind-resistant, silent load-bearing component and a concealed sash sliding window for ocean views. Background Technology

[0002] The concealed-sash sliding window with ocean view is a high-end window product designed specifically for ocean-view properties. Its sliding window employs a three-track design, with a front track, middle track, and rear track arranged sequentially from the interior to the exterior. A screen sash is installed on the rear track, while glass door sashes are installed on the front and middle tracks. The two glass door sashes are staggered or overlapped in the left-right sliding direction to open and close the window. To achieve the "concealed sash" effect, a step, handrail, or platform is typically installed at the front end of the lower track. This component conceals the lower track, making the track structure invisible from the interior, thus enhancing both the view and aesthetics.

[0003] The existing concealed-sash sliding windows for ocean views are assembled with the window sash and frame as follows: the bottom of the sliding sash slides onto the track of the lower sliding frame via pulleys, and the top of the sliding sash is embedded in the central groove of the upper sliding frame. During normal sliding, the sash only slides horizontally along the track. However, ocean view properties are constantly affected by sea winds, resulting in fluctuating wind pressure. Existing concealed-sash sliding windows suffer from swaying and noise problems caused by horizontal wind vibration. The existing sliding window sash lacks an elastic buffer structure in the indoor-outdoor direction (i.e., the horizontal direction). When sea winds blow towards the sash, the entire sash is subjected to horizontal thrust. Because the contact between the pulleys and the track, and between the upper horizontal frame and the upper sliding frame, is rigid or has assembly gaps, the wind pressure fluctuations directly cause the sash to reciprocate horizontally. This vibration is transmitted through the sash to the window frame and wall, producing low-frequency humming and impact noises, severely affecting living comfort. Furthermore, long-term vibration of the sash accelerates the wear of the pulleys and sealing strips, leading to a decrease in airtightness and watertightness. Summary of the Invention

[0004] The purpose of this invention is to provide a wind-resistant, silent load-bearing component and a concealed sash sliding window for ocean views, in order to solve one or more technical problems existing in the prior art, or at least provide a beneficial option or create conditions.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: This invention provides a wind-resistant, noise-bearing component, comprising: A sliding window sash has an upper horizontal bar and a lower horizontal bar, and at least one mounting hole is provided on the side wall of the upper horizontal bar and / or the lower horizontal bar, and a pulley assembly is provided in the lower horizontal bar; A fixed frame has an upper sliding frame and a lower sliding frame. The upper horizontal frame is freely slidably embedded in the upper sliding frame, and the lower sliding frame is provided with a track. The lower horizontal frame is slidably mounted on the track by the pulley group. A stacked elastic component, comprising at least one, including: Multiple stacked arc-shaped spring sheets, the length of each arc-shaped spring sheet decreases sequentially from the inner arc side to the outer arc side, and each arc-shaped spring sheet has a coaxial central hole in the middle. An abutment block is provided on the outer side of the outermost arc-shaped spring sheet, and its outer surface is used to press against the upper sliding frame and / or the lower sliding frame. A rod is provided at the center of the abutment block, and the rod passes through the central hole of each arc-shaped spring sheet. The telescopic outer sleeve has a screw hole at one end and a straight cylinder at the other end. The screw hole is threaded to the end of the rod. The telescopic rod has one end slidably inserted into the straight cylinder, and the other end is provided with a head and a nut for assembly in the assembly hole; Among the multiple arc-shaped spring sheets, the two ends of the main body located on the innermost arc side are bent into rounded ends and abut against the side wall of the upper or lower horizontal axis where the mounting hole is located. When the sliding window sash is subjected to the pulsation of sea wind from the indoor and outdoor directions, the abutting block is pressed by the upper sliding frame and / or the lower sliding frame, causing each arc-shaped spring sheet to be compressed and tend to be straight. At the same time, the telescopic rod retracts into the telescopic outer sleeve, and the rounded ends expand outward, converting the wind pressure into the elastic deformation of the stacked elastic components.

[0006] In a static, wind-pressure-free state, the multiple stacked arc-shaped spring sheets are in a freely bent state. The arc-shaped end of the main body abuts against the side wall of the window sash, and the outer surface of the abutting block makes slight contact or has a small gap with the abutting part of the upper sliding frame and / or lower sliding frame. The arc-shaped spring sheets are almost unforced or only subjected to pre-pressure. When the sea breeze pulsates, such as when the wind pressure blows from the outside to the inside and the sea breeze impacts the sliding window sash in a pulsed form, the entire sliding window sash is subjected to a horizontal thrust towards the inside, and the sliding window sash tends to move towards the inside. Because the abutting block is held in place by the abutting part (relatively stationary), the arc-shaped ends of both ends of the main body are forced to become the main force points, transmitting the horizontal thrust to the entire spring sheet assembly. The main body and the transition leaf are compressed, the arc height decreases, and it tends to be straight, that is, the arc-shaped ends slide outward (away from the direction of the mounting hole). The expansion and contraction between the telescopic rod and the telescopic outer sleeve provides space for the deformation of the arc-shaped spring sheets. When the arc end is compressed, the main body initially bears the concentrated load. Through the contact surface between the main body and the adjacent transition plates, the force is transferred to the second, third, and so on, with each arc-shaped spring plate sharing the overall bending stress. Compared to traditional single-layer spring plate solutions, where bending stress is concentrated on the outer arc surface under the same load, easily leading to plastic deformation or fatigue fracture, the multi-layer lamination of this invention ensures that the stress in each arc-shaped spring plate is below its fatigue limit, significantly extending its lifespan, avoiding main body fracture caused by stress concentration, and ensuring high reliability over long-term use.

[0007] As a further improvement of the present invention, the drop-down box includes: The sliding mullion has a first intermediate groove along its length, and a first supporting protrusion is provided on the first intermediate groove to form a first track; The handrail is hooked to the interior side of the sliding mullion, and the top surface of the handrail is higher than the sliding mullion and the sliding cover plate, so that the handrail blocks the track of the sliding frame and the lower horizontal of the sliding window sash on the interior side, forming a concealed sash structure. The blocking straight wall of the handrail is provided with a first abutting part for pressing the abutting block. The sliding cover has a second intermediate groove along its length, and a second supporting protrusion is provided on the second intermediate groove to form a second track. The sliding cover is fastened to the outdoor side of the sliding mullion, so that the track surfaces of the sliding mullion and the sliding cover are flush. A second abutting part is provided on the track surface of the sliding cover for pressing the abutting block.

[0008] This technical solution utilizes the straight wall of the handrail as the first abutment, achieving an aesthetically pleasing concealed fan while providing a horizontal buffer point. The supporting wall of the sliding cover serves as the second abutment, integrated into the existing components without adding any parts, resulting in a compact structure.

[0009] As a further improvement of the present invention, the sliding cover plate extends to the outdoor side and has a third intermediate groove on the top surface of the extension. The third intermediate groove has a third supporting protrusion to form a third track. The third track is parallel to the first track and the second track and is used to install the screen sash. The sliding cover plate is integrally formed, has high strength, and is easy to install. The screen sash is set separately on the outermost outdoor track and does not interfere with the glass door. When the glass door is pushed or pulled, the screen can remain closed to prevent mosquitoes and insects.

[0010] As a further improvement of the present invention, the first abutting part and the second abutting part are respectively support walls that extend continuously along the length direction, and the surface of the support wall is provided with a wear-resistant sliding layer; the outer surface of the abutting block is a smooth plane, and when the sliding window sash slides along the track, the abutting block forms a sliding friction fit with the first abutting part and / or the second abutting part. When the sliding window sash slides, the abutting block moves relative to the support wall along the length direction. Through the low-friction design, the sliding resistance is small, reducing sliding friction to avoid additional pushing and pulling force. The wear-resistant sliding layer extends the service life and adapts to high-frequency pushing and pulling.

[0011] As a further improvement of the present invention, the multiple arc-shaped spring sheets include a main sheet and at least two transition sheets, wherein the main sheet has the longest length, and the lengths of the transition sheets decrease sequentially. As the compression increases, the shorter transition sheets successively contact the load-bearing surface, and the stiffness gradually increases, achieving nonlinear variable stiffness to adapt to different wind pressures.

[0012] As a further improvement of the present invention, the outer surface of the lower horizontal sidewall and below the stacked elastic component is provided with a support protrusion extending in the length direction. The support protrusion protrudes from the sidewall surface and is used to support the bottom of the arc ends at both ends of the main body, so that the arc ends at both ends are kept at the same level.

[0013] As a further improvement of the present invention, the stacked elastic components are equidistantly distributed along the length of the upper horizontal section or distributed at both ends and the middle of the upper horizontal section; the inner wall of the upper sliding frame is a continuous plane, which serves as the third abutment part, allowing multiple abutment blocks to slide and abut simultaneously. The top of the sliding window sash is also subjected to horizontal wind pressure. By using the stacked elastic components at the upper horizontal section to press against the inner wall of the upper sliding frame, the upper part is horizontally buffered, and the upper and lower parts are buffered simultaneously, suppressing the overall tilting and swaying of the window sash. Moreover, the multi-point distribution ensures that the force is evenly distributed along the entire length of the window sash, avoiding local stress concentration.

[0014] As a further improvement of the present invention, the stacked elastic assembly has two constraint steel clips, respectively disposed near both sides of the abutment block. The constraint steel clips clamp the two edges of each arc-shaped spring sheet in the width direction, and their open ends are locked by bolts, cable ties, or buckles, thus binding the arc-shaped spring sheets tightly in the width direction to prevent them from spreading out, while allowing the arc-shaped spring sheets to slide relative to each other in the length direction and deform under pressure. The constraint steel clips prevent the multi-layered spring sheets from being misaligned or spreading out in the width direction, ensuring stacking stability, especially under pressure deformation.

[0015] On the other hand, the present invention also provides a concealed sliding window for ocean views, comprising: The window frame is formed by a fixed upper outer frame, a fixed lower outer frame, a fixed left side frame, and a fixed right side frame. Such as the aforementioned wind-resistant, silent load-bearing component; The upper fixed glass window is fixedly installed between the upper fixed outer frame, the left fixed side frame, the right fixed side frame and the upper sliding frame of the silent load-bearing component; The lower fixed glass window is fixedly installed between the lower fixed outer frame, the left fixed side frame, the right fixed side frame and the lower sliding frame of the silent load-bearing component.

[0016] When the sliding window sash of this invention slides horizontally, the pulsating pressure from the sea breeze encountered is absorbed by the stacked elastic components, achieving quiet operation and vibration resistance, and improving the comfort and durability of the entire window in coastal environments. The upper and lower fixed glass windows, together with the upper and lower sliding frames in the middle layer, form an integral structure that jointly bears the wind pressure.

[0017] As a further improvement of the present invention, the sliding frame includes a sliding mullion, the bottom of which is provided with a first glass pressure line, and the bottom outdoor side of the sliding mullion extends downward with a clamping outer wall, and a clamping gap is formed between the clamping outer wall and the first glass pressure line for clamping the top edge of the lower fixed glass window. The top of the upper sliding frame is provided with a second glass pressure line and an upper rail stop. The second glass pressure line is located on the indoor side of the upper fixed glass window and is opposite to the upper rail stop, together clamping the bottom edge of the upper fixed glass window. The bottom edge of the upper fixed glass window is also provided with a pad.

[0018] The glass pressure line in this improved design is a product used to fix the glass, providing sealing and support functions. The lower profile of the sliding mullion has an installation groove on the interior side to engage the first glass pressure line. An exterior wall extends downwards, clamping the exterior wall and forming a gap with the pressure line, with an embedded sealing strip for holding the glass. The upper profile of the upper sliding frame has an upper rail guard at the top, and a second glass pressure line on the interior side; the two clamp the bottom edge of the upper fixed glass window. An elastic pad, such as rubber or nylon, is placed at the bottom of the glass to adjust the height and provide cushioning. Attached Figure Description

[0025] Reference Figures 1 to 5 The following are several embodiments of a wind-resistant, silent load-bearing component and a sea-view concealed sash sliding window of the present invention.

[0026] Embodiments of the present invention provide a wind-resistant, silent load-bearing component, such as... Figures 1 to 4 As shown, it includes: The sliding window sash 100 has an upper horizontal sash 110 and a lower horizontal sash 120. At least one mounting hole is provided on the side wall of the upper horizontal sash 110 and / or the lower horizontal sash 120. A pulley block 130 is provided inside the lower horizontal sash 120. The fixed frame 200 has an upper sliding frame 210 and a lower sliding frame 220. The upper horizontal frame 110 is freely slidably embedded in the upper sliding frame 210. The lower sliding frame 220 is provided with a track. The lower horizontal frame 120 is slidably mounted on the track through the pulley group 130. At least one of the stacked elastic components 300 is provided, comprising: Multiple stacked arc-shaped spring sheets 310, the length of each arc-shaped spring sheet 310 decreases sequentially from the inner arc side to the outer arc side, and each arc-shaped spring sheet 310 has a coaxial central hole in the middle. The abutment block 320 is located on the outer side of the outermost arc-shaped spring sheet 310. Its outer surface is used to press against the upper sliding frame 210 and / or the lower sliding frame 220. The center of the abutment block 320 is provided with a rod, which passes through the central hole of each arc-shaped spring sheet 310. The telescopic outer sleeve 330 has a screw hole at one end and a straight cylinder at the other end. The screw hole is threaded to the end of the rod. The telescopic rod 340 has one end slidably inserted into the straight cylinder, and the other end is provided with a head 341 and a nut 342 for assembly in the assembly hole. Among the multiple arc-shaped spring sheets 310, the two ends of the main body 311 located on the innermost arc side are bent into arc ends 313, which abut against the side wall of the upper horizontal 110 or lower horizontal 120 where the mounting hole is located. When the sliding window sash 100 is subjected to the pulsation of sea wind from the indoor and outdoor directions, the abutment block 320 is pressed by the upper sliding frame 210 and / or the lower sliding frame 220, causing each arc-shaped spring sheet 310 to be compressed and tend to be straight. At the same time, the telescopic rod 340 retracts into the telescopic outer sleeve 330, and the arc ends 313 expand outward, converting the wind pressure into the elastic deformation of the stacked elastic component 300.

[0027] In this embodiment, the mounting holes are located on the indoor or outdoor sidewall of the sliding window sash. The holes are round, with a diameter slightly larger than the diameter of the telescopic rod, and are spaced apart along the length of the sliding window sash, typically 2-4 holes per sash. The stacked elastic components are installed in the mounting holes on the lower and / or upper horizontal sidewalls of the sliding window sash. The multi-layered arc-shaped spring sheets refer to each spring sheet pre-bent into an arc (arch) shape, with the inner arc side being concave (facing the window sash sidewall) and the outer arc side being convex (facing the abutment block). The abutment block is a square block with flat inner and outer sides, and a centrally fixed rod, fixed by welding or integral molding. The two ends of the main body are bent into arc shapes, forming line contact or arc surface contact with the sidewalls of the upper and / or lower horizontal sides.

[0028] In the initial assembly state, the telescopic rod is passed through the assembly hole and locked to the upper or lower horizontal side wall with a nut; the abutment block, arc-shaped spring sheet, and telescopic outer sleeve are assembled into one piece through the rod body and threads, and screwed in to an appropriate depth (pre-compression adjustment); so that the outer side of the abutment block is just in contact with the abutment part of the upper / lower sliding frame (such as the side wall of the handrail or the support wall of the sliding cover) or leaves a small gap. It should be noted that the telescopic outer sleeve and telescopic rod in this embodiment are mature complete telescopic solutions, which include structures such as guidance, anti-detachment, relative sliding, and free rotation around the axis between the two, which will not be elaborated here. The telescopic function between the telescopic outer sleeve and the telescopic rod in this embodiment is mainly to provide deformation space for the multiple stacked arc-shaped spring sheets when compressed and deformed, and its telescopic implementation can be achieved using existing technology.

[0029] In this embodiment, under static, wind-pressure-free conditions, the multiple stacked arc-shaped spring sheets are in a freely bent state. The arc end of the main body abuts against the side wall of the upper or lower horizontal sliding frame. A rubber bushing can be fitted or bonded to the outer surface of the arc end to reduce metal-to-metal hard friction between the arc end and the side wall of the upper or lower horizontal sliding frame, thereby reducing sliding noise and absorbing minor vibrations. It also buffers the micro-impact between the arc end and the side wall. The outer surface of the abutting block makes slight contact or has a small gap with the abutting part of the upper sliding frame and / or lower sliding frame. The arc-shaped spring sheets are almost unforced or only subjected to pre-pressure. When the sea breeze pulsates, such as when the wind pressure blows from the outside to the inside and the sea breeze impacts the sliding window sash in a pulsed form, the entire sliding window sash is subjected to a horizontal thrust towards the inside, and the sliding window sash tends to move towards the inside. Because the abutting block is held in place by the abutting part (relatively stationary), the arc-shaped ends at both ends of the main body become the main stress points, transmitting the horizontal thrust to the multiple stacked arc-shaped spring sheets. The main body and transition pages are compressed, the arc height decreases, and they tend to straighten, meaning the arc-shaped ends slide outwards (away from the direction of the central hole). The expansion and contraction between the telescopic rod and the telescopic outer sleeve provides space for the deformation of the arc-shaped spring sheets. When the arc-shaped ends are compressed, the main body first bears the concentrated load, and through the contact surface between the main body and the adjacent transition pages, the force is transmitted to the second, third, and so on, with each arc-shaped spring sheet sharing the overall bending stress. Compared to the traditional single-layer spring sheet solution, under the same load, its bending stress is concentrated on the outer arc surface, easily leading to plastic deformation or fatigue fracture. The multi-layer stacking in this embodiment ensures that the stress of each arc-shaped spring sheet is below its fatigue limit, significantly extending its lifespan, avoiding main body fracture caused by stress concentration, and ensuring high reliability in long-term use.

[0030] Compared to traditional solutions, conventional spring systems typically use rigidity to counteract positive pressure, a "hard-hitting" approach. Furthermore, the violent rebound of traditional springs after energy storage can lead to secondary impacts, especially when facing pulsating sea wind pressure. Traditional concealed-sash windows often exhibit continuous impact vibrations and noise, as well as window sash oscillations. This embodiment employs a "deformation-and-consumption" damping mechanism. Impact energy is converted into friction between the curved spring plates and dissipated. During wind pressure fluctuations, the window sash does not violently bounce back to its original position, thus achieving adaptive pulse buffering. Specifically, as the multiple curved spring plates tend to flatten under pressure, relative sliding between the plates generates frictional resistance. This frictional resistance increases non-linearly with increasing wind pressure (the higher the wind pressure, the tighter the plates, and the greater the frictional energy dissipation), converting some of the impact energy into heat energy for frictional dissipation. This forms an elastic buffer with damping characteristics, enabling adaptive absorption of pulsating sea wind pressure and avoiding the secondary impacts caused by the violent rebound of traditional springs after energy storage. At low wind pressure, the normal force between the spring plates is small, and the friction is low. The spring plates mainly exhibit elastic stiffness (relative rigidity), and the window sash can be balanced after a slight displacement, preventing swaying. At high wind pressure, the normal force between the spring plates is large, and the friction increases significantly. A considerable portion of the deformation energy of the spring plates is consumed by frictional heat, rather than being entirely stored as elastic potential energy and then released upon rebound. In this embodiment, the window sash moves smoothly without bouncing during sea breeze pulsations. Under high wind pressure, some of the impact energy is consumed, and the amplitude transmitted to the window frame is effectively reduced. At low pressure, the window sash remains stable and does not sway.

[0031] In an optional embodiment, such as Figure 1 and Figure 2 and Figure 5 As shown, the drop box 220 includes: The sliding mullion 221 has a first intermediate groove along its length, and a first support protrusion 222 is provided on the first intermediate groove to form a first track; The handrail 223 is hooked to the indoor side of the sliding mullion 221, and the top surface of the handrail 223 is higher than the sliding mullion 221 and the sliding cover plate 224, so that the handrail 223 blocks the track of the sliding frame 220 and the lower horizontal 120 of the sliding window sash 100 on the indoor side, forming a concealed sash structure. The blocking straight wall of the handrail 223 is provided with a first abutting part 225 for pressing the abutting block 320. The sliding cover plate 224 has a second intermediate groove along its length. The second intermediate groove has a second supporting protrusion 226 to form a second track. The sliding cover plate 224 is fastened to the outdoor side of the sliding mullion 221, so that the track surfaces of the sliding mullion 221 and the sliding cover plate 224 are flush. A second abutting part 227 is raised on the track surface of the sliding cover plate 224 to press against the abutting block 320.

[0032] In this embodiment, the sliding mullion, handrail, and sliding cover are all made of aluminum alloy profiles with a constant cross-section along their length. A first intermediate groove is formed at the top of the sliding mullion, and a first supporting protrusion, such as a stainless steel protrusion, is set within this groove. The protrusion can be single or two parallel protrusions, depending on the pulley system of the sliding window sash. Similarly, the second intermediate groove and second supporting protrusion of the sliding cover are similarly configured. The interior edge of the sliding mullion 221 bends upward to form a hook edge 2211. The handrail 223 has a corresponding C-shaped buckle 2231, which is fastened to the hook edge 2211. The handrail is quickly installed through this hook connection. The top surface of the handrail is higher than the track surface and the lower horizontal bar of the sliding window sash, making the track and lower horizontal bar invisible from the interior view, achieving a "hidden sash" effect. Simultaneously, the straight wall of the handrail provides a fixed abutment surface, i.e., the first abutment part, for the abutment block of the stacked elastic components.

[0033] Furthermore, a U-shaped opening groove 2212 is provided at the top of the sliding mullion 221, and the profile of the second intermediate groove of the sliding cover plate 224 is precisely embedded in the U-shaped opening groove 2212, so that the track surface of the sliding cover plate 224 is flush with the track surface of the sliding mullion 221, ensuring that the two window sashes slide on the same horizontal plane. A second abutment portion 227 protrudes from the track surface of the sliding cover plate 224. There are two second abutment portions integrally formed, located on the indoor and outdoor sides of the outdoor window sash, respectively. That is, the second abutment portion located on the indoor side also provides pressure for the outdoor layered elastic components of the indoor window sash. In this embodiment, the straight wall of the handrail serves as the first abutment portion, achieving an aesthetically pleasing concealed sash while providing a horizontal buffer point of force. The supporting wall of the sliding cover plate serves as the second abutment portion, integrated into the existing components without adding parts, resulting in a compact structure.

[0034] In an optional embodiment, such as Figure 2 and Figure 5 As shown, the sliding cover plate 224 extends to the outside and has a third intermediate groove on the top surface of the extension. The third intermediate groove is provided with a third supporting protrusion 228 to form a third track. The third track is parallel to the first track and the second track and is used to install the screen sash 400.

[0035] In this embodiment, the sliding cover plate extends horizontally outward (outdoors) for a certain distance, then bends upward to form a sidewall. A third intermediate groove (U-shaped groove) is formed in the horizontal extension section. The third supporting ridge is a stainless steel ridge embedded in the third intermediate groove. The screen sash is an aluminum alloy screen frame. The bottom pulley cooperates with the third track, allowing for independent pushing and pulling. In this embodiment, the sliding cover plate is integrally molded, has high strength, and is easy to install. The screen sash is separately set on the outermost outdoor track, without interfering with the glass door. When the glass door is pushed or pulled, the screen can remain closed to prevent mosquitoes and insects.

[0036] In an optional embodiment, such as Figure 2 and Figure 5 As shown, the first abutment portion 225 and the second abutment portion 227 are support walls that extend continuously along the length direction, and the surface of the support wall is provided with a wear-resistant sliding layer; the outer surface of the abutment block 320 is a smooth plane. When the sliding window sash 100 slides along the track, the abutment block 320 forms a sliding friction fit with the first abutment portion 225 and / or the second abutment portion 227. The wear-resistant sliding layer is a PTFE film, nylon strip, or a solid lubricant applied or co-extruded onto the surface of the support wall. When the sliding window sash slides, the abutment block moves relative to the support wall along the length direction. Through the low-friction design, the sliding resistance is small, reducing sliding friction to avoid additional pushing and pulling force. The wear-resistant sliding layer extends the service life and is suitable for high-frequency pushing and pulling.

[0037] In an optional embodiment, such as Figure 4 As shown, the multiple arc-shaped spring sheets include a main sheet 311 and at least two transition sheets 312. The main sheet 311 has the longest length, and the lengths of the transition sheets 312 decrease sequentially. In this embodiment, as the compression increases, the shorter transition sheets successively contact the load, and the stiffness gradually increases, achieving nonlinear variable stiffness and adapting to different wind pressures.

[0038] In an optional embodiment, such as Figures 2 to 4 As shown, the outer surface of the side wall of the lower horizontal 120 and below the stacked elastic component 300 is provided with a support protrusion 140 extending in the length direction. The support protrusion 140 protrudes from the side wall surface and is used to support the bottom of the arc ends 313 at both ends of the main body 311, so that the arc ends 313 at both ends are kept at the same level.

[0039] In this embodiment, the support protrusion is a convex ridge integrally formed on the lower horizontal sidewall, located directly below the assembly hole. It is either continuous or segmented along its length and is used to support the arc end. That is, the bottom of the arc end at both ends of the main body rests on the support protrusion and can slide along the length of the protrusion. This prevents the two ends of the main body from tilting or rotating due to uneven force when the spring sheet is compressed, ensuring that the arc end at both ends is always at the same horizontal height, thus ensuring that the arc surface of the spring sheet is symmetrically compressed and the working posture is stable.

[0040] In an optional embodiment, such as Figure 1 and Figure 3 As shown, the stacked elastic components 300 are equidistantly distributed along the length of the upper horizontal 110 or distributed at both ends and the middle of the upper horizontal 110; the inner sidewall of the upper sliding frame 210 is a continuous plane, and the inner sidewall serves as the third abutment part, allowing multiple abutment blocks to slide and abut simultaneously.

[0041] In this embodiment, the top of the sliding window sash is also subjected to horizontal wind pressure. The stacked elastic components at the top horizontal position press against the inner wall of the upper sliding frame to achieve horizontal buffering at the top. Buffering is achieved both at the top and bottom, suppressing the overall tilting and swaying of the window sash. Moreover, the multi-point distribution ensures that the force is evenly distributed along the entire length of the window sash, avoiding local stress concentration.

[0042] In an optional embodiment, such as Figure 4 As shown, the stacked elastic component 300 has two constraint steel clips 350, which are respectively arranged near the two sides of the abutment block 320. The constraint steel clips 350 clamp the two sides of the width direction of each arc-shaped spring sheet 310. The open ends are locked by bolts, cable ties or buckles to tighten each arc-shaped spring sheet 310 in the width direction to prevent them from spreading out, while allowing each arc-shaped spring sheet 310 to slide relative to each other in the length direction and be deformed by pressure.

[0043] In this embodiment, the constraint steel clamp is a metal sheet stamped into a C-shape or U-shape, with an open end that can be tightened. The open end has lugs for locking with bolts and nuts, or it can be secured with stainless steel cable ties or elastic buckles. The clamping direction is from both sides of the curved spring sheet's width direction (i.e., perpendicular to the spring sheet's length and arc height direction), binding each curved spring sheet tightly across its width. This prevents the multiple layers of spring sheets from misaligning or spreading out in the width direction (laterally), ensuring stable stacking, especially under pressure deformation. Simultaneously, it allows the curved spring sheets to slide freely and change their curvature in the length direction, because the constraint steel clamp only restricts deformation in the width direction, not the length direction, and does not affect the cushioning performance.

[0044] On the other hand, another optional embodiment of the present invention also provides a concealed sliding window with a sea view, such as... Figure 1 As shown, it includes: The window frame is formed by an upper fixed outer frame 510, a lower fixed outer frame 520, a left fixed side frame (not shown in the figure), and a right fixed side frame (not shown in the figure); A wind-resistant, silent load-bearing component as described in one or more of the above alternative embodiments; The upper fixed glass window 530 is fixedly installed between the upper fixed outer frame 510, the left fixed side frame, the right fixed side frame and the upper sliding frame 210 of the silent load-bearing component; The lower fixed glass window 540 is fixedly installed between the lower fixed outer frame 520, the left fixed side frame, the right fixed side frame and the lower sliding frame 220 of the silent load-bearing component.

[0045] In this embodiment, the entire window consists of three layers: a top fixed glass window, a middle sliding window (including a sound-absorbing load-bearing component), and a bottom fixed glass window. When the sliding window sash slides horizontally, the pulsating pressure from the sea breeze encountered is absorbed by the stacked elastic components, achieving noise reduction and vibration resistance, thus improving the overall comfort and durability of the window in coastal environments. The top and bottom fixed glass windows, together with the upper and lower sliding frames of the middle layer, form an integrated structure that collectively bears the wind pressure.

[0046] In an optional embodiment, such as Figure 1 As shown, the bottom of the sliding mullion 221 is provided with a first glass pressure line 550, and the bottom outdoor side of the sliding mullion 221 extends downward with a clamping outer wall 2213. The clamping outer wall 2213 and the first glass pressure line 550 form a clamping gap for clamping the top edge of the lower fixed glass window 540. The top of the upper sliding frame 210 is provided with a second glass pressure line 560 and an upper rail stop 570. The second glass pressure line 560 is located on the indoor side of the upper fixed glass window 530 and is opposite to the upper rail stop 570, together clamping the bottom edge of the upper fixed glass window 530. The bottom edge of the upper fixed glass window 530 is also provided with a pad 580.

[0047] In this embodiment, the glass pressure line is a product used to fix the glass, providing sealing and support functions. The lower profile of the sliding mullion has an installation groove on the indoor side to engage the first glass pressure line. An outer wall extends downwards on the outdoor side, forming a gap with the pressure line, and is fitted with a sealing strip to hold the glass. The upper profile of the upper sliding frame has an upper rail guard at the top, and a second glass pressure line on the indoor side; the two clamp the bottom edge of the upper fixed glass window. An elastic pad, such as rubber or nylon, is placed under the glass to adjust the height and provide cushioning.

[0048] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
