Technical Field
[0001] This utility model relates to the field of inward-tilting drift windows, and in particular to an inward-tilting drift window structure. Background Technology
[0002] Inward-tilting windows, as an innovative product in the modern window and door industry, combine functionality and practicality. They integrate the flexible opening of sliding windows with the ventilation advantages of inward-tilting windows. With their unique opening method and spatial adaptability, they are widely used in various scenarios such as residential, commercial buildings, and office spaces. The core feature of this type of window is that the inward-tilting window sash can be opened by drifting horizontally along the window frame, while also tilting inward at a certain angle for ventilation. This avoids the problems of traditional outward-opening windows occupying outdoor space and being susceptible to strong winds, and also solves the drawbacks of some inward-opening windows occupying indoor space when open. It meets the diverse needs of different environments for window and door opening methods, ventilation efficiency, and space utilization, and is gradually becoming one of the mainstream choices in the window and door market.
[0003] However, in actual use, the sliding opening function of the tilt-and-turn window still has obvious pain points. Because the tilt-and-turn window sash itself has a certain weight and relies on the track for guidance during the sliding process, when the user manually pushes the window sash to open or close, if the operating force is not properly controlled and the moving speed is too fast, the window sash is very likely to collide with various foreign objects around the window frame. Common objects that can cause collisions include window frame edges and adjacent window sashes (in multi-sash configurations). When a window sash slides to its opening or closing position at excessive speed, its edge may directly contact the vertical or horizontal frame. Long-term collisions can cause wear and tear on the sealing strips and deformation of the window frame, affecting not only the sealing performance of the doors and windows, leading to rainwater leakage and reduced sound insulation, but also shortening the lifespan of the window sash. In multi-sash tilt-and-turn windows, if one sash slides too quickly, it may collide with an adjacent sash that is closed or partially open. Direct impact between the two sashes' profiles and hardware can easily cause hardware to loosen and the sash to deform. In severe cases, it may even prevent the window from opening or closing properly, affecting the overall functionality of the doors and windows. Furthermore, the impact force generated during a collision can cause the glass on the window sash to vibrate and make abnormal noises. Long-term, high-frequency collisions increase the risk of glass breakage, posing a safety hazard. Most inward tilting and sliding window products on the market do not have an effective protective structure designed to address the collision problem during sliding opening. They rely solely on the user to manually control the opening speed to avoid collisions, which is insufficient to fundamentally solve the problem. Therefore, this application proposes an inward tilting and sliding window structure to solve the above-mentioned problem. Utility Model Content
[0004] The main objective of this invention is to provide an inward-tilting drift window structure that can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An inward tilting drift window structure includes a window frame, on which an inward tilting drift window sash is installed. A collision protection structure is symmetrically fixedly installed on the inward tilting drift window sash. The collision protection structure consists of a rotating frame, an adjustable support member, and an elastic fixing component. The rotating frame consists of a rectangular tube and a mounting block. The mounting block is fixedly installed at the inner end of the rectangular tube. The adjustable support member is slidably installed on the rectangular tube and consists of a base plate, an anti-detachment plate, a support plate, and a rubber block. The anti-detachment plate and the support plate are respectively fixedly installed at both ends of the base plate. The rubber block is fixedly installed at one end of the support plate. The elastic fixing component is movably installed on the outer wall of the rectangular tube and consists of a base rod, a spring, a handle, a moving plate, and a fixing tooth. The spring is sleeved on the base rod, the handle is fixedly installed at the outer end of the base rod, the moving plate is fixedly installed at the inner end of the base rod, and the fixing tooth is fixedly installed at the inner end of the moving plate.
[0006] Preferably, one end of the inward-tilting drift window sash is provided with symmetrical connecting grooves.
[0007] Preferably, the mounting block on the adjustable support is rotatably installed in the connecting groove opened at one end of the inward-tilting drift window sash, and a through hole is opened on the outer wall of the rectangular tube.
[0008] Preferably, the base plate on the elastic fixing component is slidably installed inside the rectangular tube, and the outer end of the base plate is provided with a plurality of locking grooves. The anti-detachment plate and the support plate are respectively located on both sides of the rectangular tube.
[0009] Preferably, the base rod on the elastic fixing component is movably installed in a through hole opened on the outer wall of the rectangular tube, the spring is located on the outside of the rectangular tube, and the spring is fixedly connected to the rectangular tube and the handle respectively, the movable plate is movably installed inside the rectangular tube, and the fixing tooth is inserted into the tooth groove opened at the outer end of the base plate.
[0010] Compared with the prior art, the present invention has the following beneficial effects: By installing an anti-collision protection structure consisting of a rotating bracket, adjustable supports, and elastic fixing components on the tilt-and-turn window sash, when the tilt-and-turn window sash opens or closes too quickly and is about to collide with the window frame, adjacent window sashes, or other external objects, the rubber block in the anti-collision protection structure will make contact with the object first. Utilizing the elastic properties of the rubber material itself, it buffers the impact force, preventing the tilt-and-turn window sash profile and sealing strip from directly contacting the external object. This reduces wear on the sealing strip and deformation of the profile, ensuring the sealing performance and sound insulation of the doors and windows, extending the lifespan of the window sash, and also reducing the risk of abnormal noise and breakage of the glass due to collision vibration, eliminating safety hazards. This fundamentally solves the drawback of existing tilt-and-turn windows that rely on manual speed control by the user to avoid collisions. Furthermore, the rotating bracket on the anti-collision protection structure is rotatably installed in the connecting groove of the tilt-and-turn window sash via an installation block, allowing for rotational adjustment. Therefore, when the anti-collision protection structure is not needed (such as when the window sash is in tilt-and-turn ventilation mode or in a permanently closed state), the bracket can be removed. Its rotating retraction prevents it from protruding from the sides of the tilt-and-turn window sash, thus maintaining the aesthetic appeal both indoors and outdoors. The adjustable support base is slidably installed inside the rectangular tube, allowing for flexible adjustment of the support's extension length on the rectangular tube based on the actual size of the tilt-and-turn window sash, installation scenario (e.g., single sash, multi-sash combination), and potential collision locations. This ensures the rubber block's protective position precisely aligns with collision risk points, enhancing the targeted effectiveness of the protection and adapting to different specifications and usage environments of tilt-and-turn windows. Finally, the elastic fixing component, through the elastic force of the spring, pushes the moving plate, causing the fixing teeth to stably insert into the tooth grooves of the base plate. This quickly fixes the adjustable support's position, preventing it from sliding during window sash movement and causing protection failure. When adjusting the adjustable support's position, simply pull the handle outwards, causing the base rod, moving plate, and fixing teeth to move synchronously, disengaging the fixing teeth from their tooth grooves to release the fixation. The operation is convenient and efficient, allowing users to adjust the anti-collision protection structure state at any time according to actual needs. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, an inward tilting drift window structure includes a window frame 1, an inward tilting drift window sash 2 mounted on the window frame 1, and anti-collision protection structures 3 symmetrically fixedly mounted on the inward tilting drift window sash 2. The anti-collision protection structure 3 consists of a rotating frame 4, an adjustable support member 5, and an elastic fixing component 6. The rotating frame 4 consists of a rectangular tube 7 and a mounting block 8. The mounting block 8 is fixedly mounted on the inner end of the rectangular tube 7. The adjustable support member 5 is slidably mounted on the rectangular tube 7. The adjustable support member 5 consists of a base plate 10, an anti-detachment plate 11, a support plate 13, and a rubber block 14. The anti-detachment plate 11 and the support plate 13 are respectively fixedly mounted on both ends of the base plate 10, and the rubber block 14 is fixedly mounted on one end of the support plate 13. The elastic fixing component 6 is movably installed on the outer wall of the rectangular tube 7. The elastic fixing component 6 consists of a base rod 15, a spring 16, a handle 17, a movable plate 18, and a fixing tooth 19. The spring 16 is sleeved on the base rod 15, the handle 17 is fixedly installed on the outer end of the base rod 15, the movable plate 18 is fixedly installed on the inner end of the base rod 15, and the fixing tooth 19 is fixedly installed on the inner end of the movable plate 18. By setting an anti-collision protection structure 3 consisting of a rotating frame 4, an adjustable support 5, and the elastic fixing component 6 on the inward tilting drift window sash 2, when the inward tilting drift window sash 2 moves too fast to open or close and is about to collide with the window frame 1, adjacent window sashes, or other external objects, the anti-collision protection structure 3 is activated. In the collision protection structure 3, the rubber block 14 will be the first to contact the object being collided with. Utilizing the elastic properties of the rubber material, it buffers the impact force, preventing the profile and sealing strip of the tilt-and-turn window sash 2 from directly contacting the external object. This reduces wear on the sealing strip and deformation of the profile, ensuring the sealing performance and sound insulation of the doors and windows, extending the lifespan of the window sash, and also reducing the risk of abnormal noise and breakage of the glass due to collision vibration, eliminating safety hazards and fundamentally solving the drawback of existing tilt-and-turn windows that rely on manual speed control by the user to avoid collisions. Furthermore, the rotating bracket 4 on the anti-collision protection structure 3 is rotatably installed in the connecting groove of the tilt-and-turn window sash 2 via the mounting block 8, enabling rotation... The adjustable support 5 allows the anti-collision protection structure 3 to be rotated and retracted when not needed (such as when the window sash is in an inward tilt-and-turn ventilation state or a long-term fixed closed state), preventing it from protruding from the sides of the inward tilt-and-turn window sash 2 and thus not affecting the aesthetics of the interior and exterior. The base plate 10 of the adjustable support 5 is slidably installed inside the rectangular tube 7, which can flexibly adjust the extension length of the adjustable support 5 on the rectangular tube 7 according to the actual size of the inward tilt-and-turn window sash 2, the installation scenario (such as single sash or multi-sash combination), and the potential collision position, so that the protection position of the rubber block 14 accurately corresponds to the collision risk point, improving the targeting and effectiveness of the protection, and adapting to inward tilt-and-turn windows of different specifications and usage environments.Finally, the presence of the elastic fixing component 6, through the elastic force of the spring 16, pushes the moving plate 18, causing the fixing teeth 19 to be stably inserted into the tooth groove 12 of the base plate 10. This quickly fixes the position of the adjustable support 5, preventing it from sliding during the window sash's horizontal movement and causing the protection to fail. When it is necessary to adjust the position of the adjustable support 5, simply pull the handle 17 outward, causing the base rod 15, the moving plate 18, and the fixing teeth 19 to move synchronously, disengaging the fixing teeth 19 from the tooth groove 12, thus releasing the fixation. The operation is convenient and efficient, allowing users to adjust the state of the anti-collision protection structure 3 at any time according to actual needs.
[0015] Specifically, one end of the tilt-and-turn window sash 2 is symmetrically provided with connecting grooves. When using this tilt-and-turn window structure, if the tilt-and-turn ventilation function is required, the corresponding hardware control component on the tilt-and-turn window sash 2 can be directly operated to tilt the tilt-and-turn window sash 2 inward around the hinge structure on the window frame 1 to a suitable angle. At this time, the tilt-and-turn window sash 2 maintains a tilted state to achieve ventilation, and in this state, there is no need to activate the anti-collision protection structure 3. If the sliding opening function is required to obtain a larger opening area, the sliding control component on the tilt-and-turn window sash 2 is operated in the same way to release the locking state between the tilt-and-turn window sash 2 and the window frame 1. Then, the tilt-and-turn window sash 2 is pushed along the track on the window frame 1, so that the tilt-and-turn window sash 2 moves horizontally along the track until it moves to the desired opening position and then the pushing stops, completing the sliding opening. When closing, the tilt-and-turn window sash 2 is pushed in the opposite direction to move along the track to the initial closed position, thus closing.
[0016] Specifically, the mounting block 8 on the adjustable support 5 is rotatably installed in the connecting groove opened at one end of the inward tilting window sash 2. A through hole 9 is opened on the outer wall of the rectangular tube 7. The base plate 10 on the elastic fixing component 6 is slidably installed inside the rectangular tube 7. Several locking tooth grooves 12 are opened at the outer end of the base plate 10. The anti-detachment plate 11 and the support plate 13 are located on both sides of the rectangular tube 7. The base rod 15 on the elastic fixing component 6 is movably installed in the through hole 9 opened on the outer wall of the rectangular tube 7. The spring 16 is located on the outside of the rectangular tube 7 and is fixedly connected to the rectangular tube 7 and the handle 17. The moving plate 18 is movably installed inside the rectangular tube 7. The fixing teeth 19 are inserted into the locking tooth grooves 12 opened at the outer end of the base plate 10. The mounting block 8 and the connecting groove opened at one end of the inward tilting window sash 2 are similar in size and shape. Precise matching ensures that the mounting block 8 can be stably embedded in the connecting groove without significant shaking. At the same time, there is a certain friction between the mounting block 8 and the contact wall of the connecting groove. This friction will not hinder the rotation adjustment of the mounting block 8 in the connecting groove (to meet the rotation requirements when the anti-collision protection structure 3 is retracted or unfolded), and will also provide sufficient positioning resistance for the mounting block 8 after it is rotated to a specific angle (such as when the anti-collision protection structure 3 is unfolded for protection, or when it is retracted without affecting its use). This prevents it from rotating on its own due to the translational vibration of the inward drifting window sash 2 or its own gravity without external intervention. This ensures that the anti-collision protection structure 3 is always in the preset protective position when in use and remains in the retracted state when retracted, avoiding the impact of the protective effect or the aesthetics of the interior and exterior due to the random rotation of the mounting block 8.
[0017] When the tilt-and-turn window sash 2 is in the process of sliding open or closed, if the tilt-and-turn window sash 2 moves too fast due to excessive operating force and is about to collide with the window frame 1, adjacent window sashes, or other external objects, the anti-collision protection structure 3 pre-installed on the tilt-and-turn window sash 2 will take effect first. At this time, the rubber block 14 on the adjustable support 5 in the anti-collision protection structure 3 will make priority contact with the collision object. The rubber block 14 uses its own elastic properties to absorb and buffer the impact force generated by the collision, preventing the profile of the tilt-and-turn window sash 2 from directly contacting the external object. It also prevents the sealing strip on the tilt-and-turn window sash 2 from being worn due to direct collision, thereby ensuring the tilt-and-turn window sash 2's stability. The sliding window's sealing performance and sound insulation reduce deformation of the tilt-and-turn window sash 2 profile, extending its service life. It also prevents vibration and noise from impacts, reducing the risk of glass breakage. When the anti-collision protection structure 3 is not in use, such as when the tilt-and-turn window sash 2 is in a tilt-and-turn ventilation state or a permanently closed state, it can be retracted by rotating the rotating frame 4 of the anti-collision protection structure 3. During operation, hold the rectangular tube 7 of the rotating frame 4 and rotate it around the mounting block 8. This will cause the adjustable support 5 and the elastic fixing component 6 to rotate synchronously, ultimately retracting the anti-collision protection structure 3. The protective structure 3 no longer protrudes from both sides of the inward tilting window sash 2, completing the rotation and retraction of the anti-collision protection structure 3. When it is necessary to adjust the extension length of the adjustable support 5 according to the actual size of the inward tilting window sash 2, the installation scenario, or the potential collision position, first pull the handle 17 of the elastic fixing component 6 outward by hand. The handle 17 drives the base rod 15 to move outward along the through hole 9. At the same time as the base rod 15 moves, it will pull the moving plate 18 to move outward synchronously within the rectangular tube 7. The handle 17 will stretch the spring 16, causing the spring 16 to be stretched and deformed. When the moving plate 18 moves, it will drive the fixing tooth 19 to disengage from the tooth groove 12. At this time, the fixed state of the adjustable support 5 is released. Next, push the support plate 13 or anti-detachment plate 11 of the adjustable support 5 by hand to make the base plate 10 slide inside the rectangular tube 7. Adjust the distance between the support plate 13 and the rectangular tube 7 according to actual needs. When the rubber block 14 is in the appropriate position, release the pull handle 17. At this time, the spring 16 pulls the handle 17 towards the rectangular tube 7 under the action of its own elastic restoring force. The handle 17 drives the base rod 15, the moving plate 18 and the fixed tooth 19 to move towards the base plate 10 simultaneously until the fixed tooth 19 is re-inserted into the corresponding tooth groove 12 at the outer end of the base plate 10. At this time, the adjustable support 5 is re-fixed, thus completing the adjustment operation of the adjustable support 5.
[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
