Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to a fully internally mounted, two-way anti-fall safety door and window system. Background Technology

[0002] Sliding windows are a common type of window, usually consisting of at least two movable sashes. They can be opened without taking up indoor or outdoor space, thus greatly reducing space occupancy.

[0003] In existing technologies, in order to effectively improve the waterproofing effect of sliding windows, high and low tracks are usually installed on the window frame, that is, the height of the lower track decreases from the inside to the outside, and the upper track is matched with the structure of the lower track.

[0004] Currently, the following installation method is generally used for this type of high-low track sliding window: Inside the room, the workers first tilted the innermost window sash and suspended it outside. Then, they adjusted the angle of the window sash and installed the upper part of the window sash into the upper track. Finally, they pulled the lower part of the window sash inward and installed the lower part of the window sash into the lower track. After that, the installed window sashes were slid to one side and then installed into the upper and lower tracks one by one from the inside to the outside in the same way.

[0005] However, the above installation method has at least the following technical drawbacks in actual implementation: Firstly, before installation, window sashes need to be suspended and extended outdoors. If the workers do not hold them firmly, the window sashes may fall directly, causing a serious safety accident. This is especially true for larger and heavier window sashes, where even with multiple people working together, there is still a serious risk of them falling. Although there are existing technologies that use suction cup machines to handle these larger and heavier window sashes, this greatly increases the installation cost. Secondly, before installing the window sash, it is first suspended outside. Then, the workers hold the window sash firmly and install it. Until the bottom of the window sash is installed with the lower rail, the workers need to support the weight of the entire window sash to prevent it from falling. Thus, the workers need to expend a lot of labor throughout the installation process. Furthermore, during the installation process, it is necessary to ensure that the window sash does not fall while also aligning it with the upper rail, which is an extremely difficult and troublesome task. Therefore, at least two workers are generally required to work together, which further increases the labor force. Summary of the Invention

[0006] Based on the above-mentioned technical problems, the present invention provides a fully internally mounted two-way anti-fall safety door and window system to solve the technical defects in the prior art, which uses the method of first extending the window sash outside the window and then installing it, making the window sash easy to fall off and thus causing major safety accidents.

[0007] The objective of this invention is achieved through the following technical solution: A fully internally mounted, two-way anti-fall safety door and window system includes an upper track assembly, a lower track assembly, and multiple window sashes slidably disposed between the two; the top of the lower track assembly is provided with multiple lower sliding rails arranged sequentially from the inside to the outside, and the bottom of the upper track assembly is provided with multiple upper sliding grooves adapted to the lower sliding rails; a sliding device is installed between the window sash and the upper sliding groove located directly above it.

[0008] Preferably, the sliding device includes an upper slide rail and a first pulley assembly that slides with the upper slide rail; the top end of the upper slide groove and the top end of the window sash are provided with the upper slide rail at one end and the first pulley assembly at the other end.

[0009] Preferably, a first upper baffle and a first lower baffle are respectively provided on the outer side of the upper track group and the lower track group.

[0010] Preferably, a second upper baffle is detachably provided on the inner side of the upper track assembly.

[0011] Preferably, a second lower baffle is provided on the inner side of the lower track assembly.

[0012] Preferably, a baffle rail is provided at the bottom outer side of the window sash, and a sliding groove is provided at the top of the lower track assembly and directly below the baffle rail; the bottom end of the baffle rail extends into the sliding groove; and a drainage hole is provided on the side wall of the sliding groove.

[0013] Preferably, the sliding groove is provided with a second pulley assembly that slides in cooperation with the stop rail.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention features multiple lower sliding rails arranged sequentially from high to low at the top of the lower track group, and multiple upper sliding grooves adapted to the lower sliding rails at the bottom of the upper track group. This allows the window sashes to be distributed in a stepped manner from the inside to the outside. During installation, the outer window sash is installed first. Specifically, the window sash is tilted and moved between the upper and lower track groups. Then, the bottom of the window sash is directly aligned with the outermost lower sliding rail, and the bottom of the window sash is slid onto the lower sliding rail. At this point, the lower sliding rail can bear most of the weight of the window sash and limit the bottom of the window sash. The worker does not need to use much force; they only need to hold the window to prevent it from tilting and falling, greatly reducing the worker's labor intensity. Afterward, the worker only needs to push the top of the window sash outward. When the top of the window sash is directly below the upper sliding groove, the sliding device is installed between the upper sliding groove and the window sash, thus limiting the distance between the window sash and the upper sliding groove and ensuring that the window sash can slide smoothly within the upper sliding groove. Then, following the same procedure, install the remaining window sashes one by one.

[0015] Through the synergistic effect of the above-mentioned devices, the window sash does not need to be suspended outside the window during the entire installation process, thus achieving fully internal installation and completely preventing the window sash from falling. This effectively overcomes the defect of existing technologies where the window sash falls due to being suspended outside the window, which can lead to major safety accidents. At the same time, by installing the bottom of the window sash first, the workers can reduce the force required for subsequent installations after the bottom of the window sash is installed, greatly reducing the workload of the workers.

[0016] Furthermore, by setting a sliding device and a sliding engagement between the window sash and the lower track, the window sash can be limited between the upper track group and the lower track group, thereby ensuring the stability of the window sash during use. Attached Figure Description

Detailed Implementation

[0018] Example 1 A fully internally mounted, two-way anti-fall safety door and window system, such as Figure 1-2 As shown, the system includes an upper track assembly 1, a lower track assembly 2, and multiple sliding window sashes 3 slidably disposed between them. Furthermore, in actual implementation, in addition to the sliding window sashes 3, the window system may also install fixed window sashes, such as... Figure 1 and Figure 2 As shown, the door and window system includes an upper track assembly 1, a lower track assembly 2, a left frame 31, a right frame 32, and a lower frame 33. A sliding window sash 3 is installed between the upper track assembly 1 and the lower track assembly 2, while a fixed window sash is installed between the lower track assembly 2 and the lower frame 33. Figure 2 The glass inside window 3 is not drawn, nor is the fixed window between the lower track group 2 and the lower frame 33. Figure 2 and Figure 3 【 Figure 3 exist Figure 2 Based on this, the bottom border shown in Figure 33 has been removed. The top of the lower track group 2, from the inside to the outside (the inside and outside mentioned in the text refer to indoor and outdoor areas, based on the attached figure) Figure 1 The orientation is as follows: outdoors, it's on the left; indoors, it's on the right. Additionally... Figure 2 and Figure 3 [Second pulley assembly 14 not shown] Multiple lower sliding rails 4 are arranged sequentially from high to low, i.e., the lower sliding rails 4 are arranged in a stepped manner. The bottom of the upper rail assembly 1 is provided with multiple upper sliding grooves 5 that are adapted to the lower sliding rails 4, i.e., the upper sliding grooves 5 are also arranged in a stepped manner. A window sash 3 is provided between the lower sliding rails 4 and the upper sliding grooves 5 located directly above them. Figure 4 As shown, a sliding device is installed between the window sash 3 and the upper sliding groove 5 located directly above it; a plurality of third pulleys 16 (existing technology) are installed at the bottom end of the window sash 3 along the pushing and pulling direction, and the third pulleys 16 are slidably connected to the lower sliding rail 4 that is adapted to them.

[0019] It is worth noting that the window sash 3 includes a glass sash or a hybrid sash of a glass sash and a screen. Generally speaking, the screen is installed closer to the interior side, which is the prior art.

[0020] Working principle: When installing window sash 3, the outer window sash 3 needs to be installed first. Specifically, as follows... Figure 5 ( Figure 5 As shown in the diagram (excluding the bottom border 33 and the glass inside the window sash 3), the window sash 3 is first tilted and moved between the upper track group 1 and the lower track group 2. Then, the straight bottom end of the window sash 3 is aligned with the outermost (i.e., the left) lower slide rail 4, so that the third pulley 16 at the bottom of the window sash 3 is slidably installed on the lower slide rail 4. At this time, the lower slide rail 4 can bear most of the weight of the window sash 3 and limit the lower end of the window sash 3. At this time, the staff does not need to use too much force, but only needs to hold the window to prevent the window sash 3 from tilting and falling, which greatly reduces the burden on the staff. Then, the staff only needs to push the upper part of the window sash 3 outward. When the top of the window sash 3 is pushed to the bottom of the upper left slide groove 5, the window sash 3 is in a vertical state, and there is a certain gap between the window sash 3 and the bottom of the upper slide groove 5. The sliding device is then installed between the upper sliding groove 5 and the window sash 3, thereby limiting the distance between the window sash 3 and the upper sliding groove 5. At the same time, the sliding device ensures that the window sash 3 can slide smoothly within the upper sliding groove 5.

[0021] Then, following the same procedure, install the remaining window sashes 3 one by one.

[0022] Through the synergistic effect of the above-mentioned devices, the present invention has at least the following advantages: Firstly, the window sash 3 does not need to be suspended outside the window during the entire installation process, thus achieving fully internal installation and completely avoiding the risk of the window sash 3 falling. This effectively overcomes the defect in the existing technology where the window sash 3 falls due to being suspended outside the window, which could lead to a major safety accident. Secondly, during installation, the bottom of the window sash 3 is first installed onto the sliding rail 4. The sliding rail 4 supports the weight of the window sash 3, which reduces the subsequent installation effort and load on the workers. Unlike existing technologies, it does not require maintaining a high load-bearing capacity from the start to the end of installation, thus greatly reducing the workload of the workers. Third, the entire installation only requires aligning the lower end of the window sash 3 with the sliding rail 4. Unlike existing technologies, which require aligning the upper and lower ends of the window sash 3 with the upper and lower sliding rails 4 respectively, this method requires fewer personnel and is more convenient to operate.

[0023] Furthermore, by setting a sliding device and the sliding cooperation between the third pulley 16 assembly at the bottom of the window sash 3 and the lower rail 4, the window sash 3 can be limited to the upper rail group 1 and the lower rail group 2, thereby ensuring the smooth sliding of the window sash 3.

[0024] Furthermore, based on Example 1, such as Figure 4 As shown, the sliding device includes an upper slide rail 6 and a plurality of first pulley assemblies 7 that slide in cooperation with the upper slide rail 6; the top end of the upper slide groove 5 and the top end of the window sash 3, wherein the upper slide rail 6 is provided at one top end and the first pulley assembly 7 is provided at the other top end. Figure 4 As shown, the present invention provides an embodiment in which an upper slide rail 6 is provided at the top of the upper slide groove 5, and a first pulley assembly 7 that slides and engages with the upper slide rail 6 is provided at the top of the window sash 3. The working principle of this solution is as follows: The upper sliding rail 6 is pre-installed at the top of the upper sliding groove 5. When the window sash 3 is installed, as its top moves directly below the upper sliding groove 5, multiple first pulley assemblies 7 are inserted one by one into the upper sliding groove 5 and the groove 34 at the top of the window sash 3. The first pulley assemblies 7 are then fixed to the window sash 3 with bolts. After the first pulley assemblies 7 are installed, they slide in contact with the upper sliding rail 6. Through the sliding contact between the upper sliding rail 6 and the first pulley assemblies 7, and the sliding contact between the lower sliding rail 4 and the third pulley 16, the window sash 3 can slide freely within the upper and lower track assemblies, while simultaneously limiting the movement of the window sash 3 to ensure it always moves between the upper and lower sliding rails 4.

[0025] Furthermore, although in Embodiment 1, by setting a sliding device and the sliding cooperation between the third pulley 16 at the bottom of the window sash 3 and the lower track 4, the window sash 3 can be limited between the upper track group 1 and the lower track group 2 to ensure the stability of the window sash 3, the sliding device and the sliding cooperation between the third pulley 16 assembly and the lower track 4 can only maintain the stability of the window sash 3 when it is not subjected to significant external impact. However, once subjected to a large horizontal impact force, such as a large impact force on the window sash 3 indoors, it is very easy for the window sash 3 to derail and fall outwards, thereby causing a major safety accident. Based on this, if Figure 2 As shown, a first upper baffle 8 and a first lower baffle 9 are respectively provided on the outer side (i.e., the left side) of the upper track group 1 and the lower track group 2. By providing the first upper baffle 8 and the first lower baffle 9, the outside of the window sash 3 can be effectively blocked, thereby ensuring that the window sash 3 will not fall outward when subjected to a large impact force from the indoor to the outdoor direction, effectively avoiding falling accidents and improving the safety of using the window sash 3.

[0026] In addition, by setting the first upper baffle 8 and the first lower baffle 9, the external impact force, such as wind pressure, can be resisted to a certain extent, thereby effectively reducing the impact of wind pressure on the window sash 3 and effectively improving the deformation resistance and pressure resistance of the door and window system.

[0027] In addition, the first upper baffle 8 can block rainwater from the outside, thereby effectively improving the wind and rain resistance of the window sash 3.

[0028] Furthermore, since the first upper baffle 8 and the first lower baffle 9 can only prevent the window sash 3 from falling outwards, they cannot guarantee that the window sash 3 will not fall inwards. When the window sash 3 is subjected to a large force from the outside, such as wind pressure, the window sash 3 may derail and fall into the room. Based on this, if... Figure 2 As shown, a second upper baffle 10 is detachably installed on the inner side of the upper track assembly 1. In this design, the second upper baffle 10 needs to be installed after all window sashes 3 are installed. By setting the second upper baffle 10, the window sashes 3 can be effectively prevented from falling into the room.

[0029] Furthermore, based on the second upper baffle 10, a second lower baffle 11 is provided on the inner side of the lower track assembly 2 to further ensure that the window sash 3 will not fall into the room.

[0030] Furthermore, the distance between the window sash 3 and the bottom end of the upper sliding groove 5 is 5mm. In this solution, a brush strip or brush (existing technology, not shown in the figure) is installed in the gap between the window sash 3 and the bottom end of the upper sliding groove 5 to fill the gap; in addition, because the gap is small, the gap between the window sash moving up and down is small, thereby further reducing the risk of the sash falling.

[0031] The first baffle 9 can provide some protection against wind pressure and rainwater; however, due to its limited height, its effectiveness is limited, especially during severe storms and blizzards. Therefore, if... Figure 2 As shown, a baffle rail 12 is provided at the bottom outer side of the window sash 3, and a sliding groove 13 is provided at the top of the lower track group 2 and directly below the baffle rail 12; the bottom end of the baffle rail 12 extends into the sliding groove 13; in addition, a drainage hole (existing technology, not shown in the figure) is provided on the side of the sliding groove 13 near the outside.

[0032] In this design, the baffle 12 and the sliding groove 13 serve at least the following functions: Firstly, by extending the bottom end of the guide rail 12 into the sliding groove 13, the outside of the window sash 3 can be further blocked, thereby further improving the outward anti-falling performance of the window sash 3.

[0033] Secondly, under the action of the first lower baffle 9, the lower groove 13 and the baffle rail 12, a multi-level curved structure can be formed on the outer side of the window sash 3. This allows the external airflow, such as wind pressure, to diffuse along the multi-level curved structure when it acts on the window sash 3. This effectively reduces the degree of wind pressure diffusion to the inner side of the window sash 3, thereby effectively reducing the effect of wind pressure on the window sash 3 and effectively preventing the window sash 3 from derailing and deforming due to prolonged exposure to the wind.

[0034] In addition, a multi-stage obstruction is formed between the first lower baffle 9, the baffle rail 12, and the cavity 35 between the baffle rail 12 and the lower slide rail, thereby creating negative pressure at the lower slide groove 13, allowing the wind to be discharged directly along the lower slide groove 13, increasing the wind pressure guidance, reducing the degree of wind diffusion to the indoor side, and improving the drainage capacity.

[0035] Thirdly, based on the initial blocking of rainwater by the first lower baffle 9, the baffle rail 12 can further block rainwater. At the same time, in the face of heavy rain, it can guide the rainwater falling on the window frame along the outside of the baffle rail 12 into the sliding groove 13, and then discharge it along the drainage hole, thereby improving the storm resistance performance of the door and window system and effectively preventing rainwater from falling directly between the window sash 3 and the lower track group 2, causing water to accumulate in the lower track group 2, and even seeping into the room when the rain is heavy.

[0036] In existing technology, a row of pulleys is often installed at the bottom of the window sash 3, and a track adapted to the pulleys is installed at the top of the lower track group. In order to improve the smoothness of the movement of the window sash 3, the pulleys need to be located in the middle of the window sash 3. However, the load-bearing capacity of a single track is poor. Therefore, in order to improve the load-bearing capacity of the track, a track is often added directly to the top of the lower track group 2, that is, two tracks are set. The setting of two tracks can effectively increase the load-bearing capacity. However, in actual implementation, the distance between the two tracks is too close. This not only easily leads to dust accumulation in the gap between the tracks, but also prevents the center of gravity of the window sash from being in the center of its own position as it is with a single track. This will directly cause uneven force on the window sash, resulting in tilting, and thus causing excessive wear of the pulleys. This not only greatly shortens the service life of the product, but may even lead to the direct scrapping of the product, and may also cause the window sash to derail and fall. Based on this, such as Figure 4As shown, a second pulley assembly 14 is provided in the sliding groove 13, which slides in cooperation with the baffle rail 12. The number of second pulley assemblies 14 is determined according to the force and weight of the window sash 3 during actual installation. A cover plate 24 is provided between adjacent second pulley assemblies 14 to prevent dust accumulation between them. In actual implementation, the baffle rail 12 is biased towards the outside and extends downward, while the sliding rail 4 is biased towards the inside. The distance between them is greater than that of two rows of pulleys directly installed at the bottom of the window sash 3, and there is a certain height difference, which can effectively prevent dust accumulation. At the same time, the greater distance between the baffle rail 12 and the sliding rail 4 can make the window sash 3 bear the force evenly, effectively preventing the window sash 3 from tilting, thereby reducing the wear of the second pulley assembly 14 and the third pulley 16, and effectively improving the service life of the product. Furthermore, in order to effectively reduce the phenomenon that the stop rail 12 will collide with the second pulley assembly 14 during the sliding process of the window sash 3, thereby causing the window sash 3 to vibrate slightly, rounded corners are provided on the left and right sides of the stop rail 12.

[0037] Furthermore, the second pulley assembly 14 is equipped with an adaptive leveling device (this is existing technology, such as the elastic adaptive leveling structure commonly used in automotive suspension systems). Specifically, it is installed between the pulley shaft of the second pulley assembly 14 and the inner wall of the mounting cavity 22 of the placement box 21, and is fixedly connected to the shaft and mounting cavity 22 by bolts or clips. When this device is in operation, it can compensate for slight tilting of the window sash 3 in real time through its elastic extension or angle adaptive adjustment function: when the window sash 3 tilts due to force fluctuations or installation errors, the adaptive leveling device will drive the pulley shaft to synchronously fine-tune the angle, ensuring that the pulley always maintains a tight fit with the guide rail 12, avoiding support gaps between them, thereby ensuring the continuous and stable support of the guide rail 12 by the second pulley assembly 14, further improving the stability and anti-fall reliability of the window sash 3 during sliding.

[0038] It is worth noting that the first pulley assembly 7 and the second pulley assembly 14 in this invention can be any pulley from the prior art. Furthermore, this invention also provides a pulley assembly structure suitable for either the first pulley assembly 7 or the second pulley assembly 14, specifically as follows: Figures 6-7 As shown, the system includes a placement box 21, a mounting cavity 22 located at the top of the placement box 21, pulleys rotatably disposed within the mounting cavity 22, and connecting plates 23 disposed on both sides of the placement box 21, with mounting holes through the connecting plates 23. In a specific implementation, the second pulley assembly 14 is arranged at equal intervals within the lower sliding groove 13 along the moving direction of the window sash 3. Subsequently, the connecting plates 23 are fixed to the bottom wall of the lower sliding groove 13 using bolts. Finally, as shown... Figure 6As shown, a cover plate 24 is provided between adjacent placement boxes 21.

[0039] Furthermore, the upper slide rail 6 and the lower slide rail 4 described in this invention can be stainless steel tracks.
