Description

Technical Field

[0001] This utility model belongs to the technical field of door and window hardware accessories, specifically involving linkage modules, linkage mechanisms, and linkage door and window systems. Background Technology

[0002] Interlocking door and window systems offer great convenience to users by enabling the simultaneous opening and closing of multiple doors and windows, and are widely used in various building scenarios, such as residential, commercial, and industrial buildings. Interlocking door and window systems typically consist of multiple door and window sashes, which are linked together by a specific transmission mechanism.

[0003] In existing technologies, the linkage structure of most interlocking door and window systems employs a relatively complex design. A common linkage method involves installing multiple independent transmission components on each door and window sash, then connecting these components through complex transmission mechanisms such as chains, linkages, or gear sets to achieve linkage between the door and window sashes. While this design achieves the linkage function, it has the following significant drawbacks: the installation process is extremely cumbersome and complex. Because it involves the installation of multiple independent components and the precise connection and adjustment between them, it demands a high level of professional skill and experience from the installers. Installers not only need to be familiar with the installation location and method of each component but also must possess the ability to precisely adjust the relative positions and transmission relationships between the components to ensure the entire linkage system functions properly. This not only increases installation time and labor costs but also, due to the varying skill levels of installers, easily leads to installation errors, causing the linkage system to malfunction and requiring repeated adjustments and corrections, further extending the installation cycle and reducing installation efficiency.

[0033] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0034] Please see Figures 1 to 4This application provides a linkage module 100 for a linked door and window system. The linked door and window system includes a first door / window sash 10, a second door / window sash 20, and a third door / window sash 30. The second door / window sash 20 is located between the first door / window sash 10 and the third door / window sash 30. The linkage module 100 includes a base assembly 1, a first mounting component 2, and a first transmission assembly 3. The base assembly 1 is used to install on the second door / window sash 20. The base assembly 1 includes a connecting rod 11, a first connecting seat 12, and a second connecting seat 13. The first connecting seat 12 is connected to the first end of the connecting rod 11, and the second connecting seat 13 is connected to the second end of the connecting rod 11. The second end; the first mounting member 2 is disposed on the first connecting seat 12; the first transmission assembly 3 includes a first pulley 31, a first transmission belt 32 and two first transmission members 33; the first pulley 31 is rotatably disposed on the second connecting seat 13; the two first transmission members 33 are detachably connected to the first mounting member 2; the first transmission belt 32 is wound around the first pulley 31, and the two free ends of the first transmission belt 32 are respectively connected to the two first transmission members 33; wherein, after the two first transmission members 33 are detached from the first mounting member 2, one of the first transmission members 33 is used to fix to the first door and window sash 10, and the other first transmission member 33 is used to fix to the third door and window sash 30.

[0035] The linkage module 100 provided in this application embodiment can be shipped as a whole, and after shipment, the linkage module 100 can be directly installed on the second door / window sash 20. Specifically, after installing the base assembly 1 on the second door / window sash 20, the two first transmission components 33 are removed from the first mounting component 2, and finally the two first transmission components 33 are installed on the first door / window sash 10 and the third door / window sash 30 respectively. In this way, the entire installation process is simple and easy to understand, requires low skill from installers, and does not require complex training for installers to assemble the linkage door / window system, greatly reducing installation time and labor costs and improving installation efficiency.

[0036] It should be noted that when actually installing the base assembly 1, the appropriate installation position and fixing method can be selected according to the size and structure of the second door / window sash 20, such as using bolts, clips, etc. to securely install the base assembly 1 on the second door / window sash 20.

[0037] In one embodiment, after the two first transmission components 33 are detached from the first mounting component 2, one first transmission component 33 is inserted into the first door / window sash 10, and the other first transmission component 33 is inserted into the third door / window sash 30. This insertion installation method is extremely simple, requiring no advanced professional skills or complex training from the installers. Firstly, installation is completed simply by accurately inserting one first transmission component 33 into the corresponding slot or hole of the first door / window sash 10 and the other first transmission component 33 into the corresponding slot or hole of the third door / window sash 30. This significantly lowers the technical barrier to installation, allowing ordinary installers to quickly get started, effectively shortening installation time and improving overall installation efficiency. Secondly, the insertion structure usually has a clear guiding and positioning function. The slots or holes on the first transmission component 33 and the door and window sash are designed to match each other. During installation, the first transmission component 33 can be naturally guided to the correct position to ensure the accuracy of installation. This helps to ensure the accuracy of the relative positions between the components of the linkage module 100, so that the linkage door and window system is more stable and reliable during operation, and reduces operational failures caused by installation deviations, such as asynchronous opening of door and window sashes and jamming.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the first mounting member 2 has first connecting holes 21 on both sides, and each first transmission member 33 has a second connecting hole 331. The linkage module 100 also includes a first fastener 7, which is detachably connected to the first connecting hole 21 and the second connecting hole 331. Thus, the first fastener 7 adopts a detachable connection method, greatly simplifying the installation and disassembly process of the first mounting member 2 and the first transmission member 33. At the factory stage of the linkage module 100, workers can quickly and accurately insert the first fastener 7 into the first connecting hole 21 and the second connecting hole 331 and fix it, completing the assembly of the first mounting member 2 and the first transmission member 33. When it is necessary to install the first transmission member 33 onto a door or window sash, the first transmission member 33 can be easily separated from the first mounting member 2 by simply removing the first fastener 7, without the need for complicated tools and operating procedures, saving time and labor costs.

[0039] like Figure 2 and Figure 3As shown, in one embodiment, the first mounting component 2 is provided with a limiting groove 22; when the first transmission component 33 is connected to the first mounting component 2, the outer side wall of the first transmission component 33 is engaged in the limiting groove 22. Thus, during the assembly of the first transmission component 33 and the first mounting component 2 at the factory stage of the linkage module 100, the limiting groove 22 plays a significant positioning role. Workers only need to align the outer side wall of the first transmission component 33 with the limiting groove 22 and engage it to quickly complete the initial connection between the two, eliminating the need for complex alignment and adjustment operations. This greatly simplifies the installation process, improves installation efficiency, and reduces installation difficulty and the skill requirements for installers.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the first mounting member 2 is detachably connected to the first connecting seat 12. After the two first transmission members 33 are detached from the first mounting member 2 and then installed on the first door / window sash 10 and the third door / window sash 30 respectively, the first mounting member 2 can be further detached from the first connecting seat 12. In this way, removing the first mounting member 2 from the first connecting seat 12 can free up some space. This not only makes the layout around the doors and windows simpler and avoids unnecessary parts occupying space, but also prevents the first mounting member 2 from interfering with the normal operation of the doors and windows or surrounding items during subsequent use.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the first mounting member 2 is provided with a third connecting hole 23, the first connecting seat 12 is provided with a fourth connecting hole 121, and the linkage module 100 further includes a second fastener 8, which is detachably connected to the third connecting hole 23 and the fourth connecting hole 121. Thus, when it is necessary to remove the first mounting member 2, the second fastener 8 can be removed.

[0042] In one embodiment, the length of the connecting rod 11 is adjustable. By adjusting the length of the connecting rod 11, the relative distance between the first connecting seat 12 and the second connecting seat 13 can be adjusted to fit the size of the second door / window sash 20. Thus, firstly, the size of the second door / window sash 20 may vary due to design differences, customization requirements, or different building specifications. The adjustable length of the connecting rod 11 allows installers to precisely adjust the relative distance between the first connecting seat 12 and the second connecting seat 13 according to the actual size of the second door / window sash 20. By flexibly adjusting the length of the connecting rod 11, accurate fitting of the first connecting seat 12 and the second connecting seat 13 is ensured, achieving precise installation of the door / window system and avoiding installation difficulties or inability to install due to size mismatch. Secondly, if problems such as misalignment of the first connecting seat 12 or the second connecting seat 13 or poor transmission occur during the use of the door and window system, it may be due to an unsuitable length of the connecting rod 11. Since the length of the connecting rod 11 is adjustable, maintenance personnel can easily check and adjust the length of the connecting rod 11, quickly locate and solve the problem without disassembling a large number of parts, shorten maintenance time, reduce maintenance difficulty, and improve the maintainability of the linkage door and window system.

[0043] like Figure 3 As shown, in one connection method, the connecting rod 11 includes a first rod body 111 and a second rod body 112 that are slidably connected, a first connecting seat 12 is disposed on the first rod body 111, and a second connecting seat 13 is disposed on the second rod body 112.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the linkage module 100 further includes a second mounting member 4 and a second transmission assembly 5; the second transmission assembly 5 includes a second pulley 51, a second transmission belt 52, and two second transmission components 53; the second mounting member 4 is disposed on the second connecting seat 13, the second pulley 51 is rotatably disposed on the first connecting seat 12, the two second transmission components 53 are detachably connected to the second mounting member 4, the second transmission belt 52 is wound around the second pulley 51, and the two free ends of the second transmission belt 52 are respectively connected to the two second transmission components 53; after the two second transmission components 53 are detached from the second mounting member 4, one second transmission component 53 is used to fix to the first door / window sash 10, and the other second transmission component 53 is used to fix to the third door / window sash 30. Thus, when the two second transmission components 53 are respectively fixed to the first door / window sash 10 and the third door / window sash 30, the entire linkage module 100 forms a stable structural system, which can effectively resist interference from external factors, such as wind and vibration, reducing the probability of failure and extending the service life of the door and window system.

[0045] In one embodiment, the second mounting member 4 is detachably connected to the second connecting seat 13. After the two second transmission members 53 are detached from the second mounting member 4 and then installed on the first door / window sash 10 and the third door / window sash 30 respectively, the second mounting member 4 can be further detached from the second connecting seat 13. In this way, removing the second mounting member 4 from the second connecting seat 13 can free up some space, which not only makes the layout around the doors and windows simpler and avoids unnecessary parts occupying space, but also prevents the second mounting member 4 from interfering with the normal operation of the doors and windows or surrounding items during subsequent use.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the first mounting member 2 is provided with a third connecting hole 23, the first connecting seat 12 is provided with a fourth connecting hole 121, and the linkage module 100 further includes a second fastener 8. The second fastener 8 is detachably connected to the third connecting hole 23 and the fourth connecting hole 121, and one end of the second fastener 8 can press against the second transmission belt 52. Thus, when it is necessary to remove the first mounting member 2, the second fastener 8 can be removed to take out the first mounting member 2, which is simple and convenient. After the first mounting member 2 is removed, the second fastener 8 can be reconnected to the fourth connecting hole 121 so that one end of the second fastener 8 can press against the second transmission belt 52. This design provides a convenient and effective way to adjust the tension of the second transmission belt 52. By adjusting the tightness of the second fastener 8, its pressure on the second transmission belt 52 can be changed, thereby precisely controlling the tightness of the second transmission belt 52.

[0047] In one embodiment, the second mounting member 4 is provided with a fifth connecting hole (not labeled in the figure), the second connecting seat 13 is provided with a sixth connecting hole (not labeled in the figure), and the linkage module 100 also includes a third fastener (not labeled in the figure). The third fastener is detachably connected to the fifth connecting hole and the sixth connecting hole, and one end of the third fastener abuts against the first transmission belt 32. Thus, when it is necessary to remove the second mounting member 4, the third fastener can be removed to take out the second mounting member 4, which is simple and convenient. After the second mounting member 4 is removed, the third fastener can be reconnected to the sixth connecting hole so that one end of the third fastener can abut against the first transmission belt 32. This design provides a convenient and effective way to adjust the tension of the first transmission belt 32. By adjusting the tightness of the third fastener, its pressure on the first transmission belt 32 can be changed, thereby precisely controlling the tightness of the first transmission belt 32.

[0048] In one embodiment, the second mounting member 4 has a seventh connecting hole (not labeled) on both sides, and each second transmission member 53 has an eighth connecting hole (not labeled). The linkage module 100 also includes a fourth fastener (not labeled), which is detachably connected to the seventh and eighth connecting holes. This detachable connection of the fourth fastener greatly simplifies the installation and disassembly process of the second mounting member 4 and the second transmission member 53. During product shipment, workers can quickly and accurately insert and fix the fourth fastener into the seventh and eighth connecting holes to complete the assembly of the second mounting member 4 and the second transmission member 53. When the second transmission member 53 needs to be installed on a door or window sash, it can be easily separated from the second mounting member 4 by simply removing the fourth fastener, without the need for complex tools and procedures, saving time and labor costs.

[0049] like Figure 4 As shown, in one embodiment, the linkage module 100 is used to be installed on the upper side of the second door / window sash 20. The linkage module 100 also includes two second hangers 6, which are respectively connected to the first connecting seat 12 and the second connecting seat 13 on the second door / window sash 20. The two second hangers 6 are respectively used to connect to two second pulleys 700 in the second track groove of the upper track.

[0050] It should be noted that in some other embodiments, the linkage module 100 can also be installed on the lower side of the second door / window sash 20, depending on the actual needs.

[0051] like Figure 4 , Figure 5 and Figure 6 As shown, this application embodiment also provides a linkage mechanism, including the linkage module 100 as described in any of the above embodiments, and two third connecting seats 400. Each third connecting seat 400 is provided with a first insertion slot 401. The two third connecting seats 400 are respectively used to fix the first door / window sash 10 and the third door / window sash 30. After the two first transmission members 33 are detached from the first mounting member 2, the two first transmission members 33 can be respectively inserted into the first insertion slots 401 of the two third connecting seats 400.

[0052] like Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the linkage mechanism further includes two fourth connecting seats 500, each of which is provided with a second insertion slot (not labeled in the figure). The two fourth connecting seats 500 are respectively used to fix the first door / window sash 10 and the third door / window sash 30. After the two second transmission members 53 are detached from the second mounting member 4, the two second transmission members 53 can be respectively inserted into the second insertion slots of the two fourth connecting seats 500.

[0053] like Figure 5 As shown, in one embodiment, the linkage mechanism further includes two first hangers 200, which are respectively connected to a third connecting seat 400 and a fourth connecting seat 500 on the first door / window sash 10, and two second hangers 6 are respectively used to connect to two first pulleys 600 in the first track groove of the upper track.

[0054] like Figure 6 As shown, in one embodiment, the linkage mechanism further includes two third rods 300, which are respectively connected to a third connecting seat 400 and a fourth connecting seat 500 on the third door / window sash 30. The two third rods 300 are respectively used to connect to two third pulleys 800 in the third track groove of the upper track.

[0055] like Figure 6 and Figure 7 As shown, this application embodiment also provides a linkage door and window system, including the linkage mechanism as described in any of the above embodiments, and further including a first door and window sash 10, a second door and window sash 20 and a third door and window sash 30, a seat assembly 1 disposed on the second door and window sash 20, two third connecting seats 400 respectively fixed to the first door and window sash 10 and the third door and window sash 30, and two fourth connecting seats 500 respectively fixed to the first door and window sash 10 and the third door and window sash 30.

[0056] The installation process for this linked door and window system is as follows:

[0057] The linkage module 100 is installed on the upper side of the second door / window sash 20. Specifically, the seat assembly 1 is installed on the upper side of the second door / window sash 20 according to its dimensions, ensuring that the first connecting seat 12 and the second connecting seat 13 are positioned at the matching ends of the second door / window sash 20, so that both the first transmission belt 32 and the second transmission belt 52 are taut to achieve stable linkage. Furthermore, the second door / window sash 20 can be hoisted onto the upper track via the connection between the second hanging rod 6 and the second pulley 700, and the first door / window sash 10 can be hoisted onto the upper track via the connection between the first hanging rod 200 and the first pulley 600. After the third door / window sash 30 is hoisted onto the upper track via the connection between the third hanger 300 and the third pulley 800, the first door / window sash 10 and the second door / window sash 20 are slid to the appropriate positions. Then, the two first transmission components 33 are inserted into the two third connecting seats 400 respectively, and the two second transmission components 53 are inserted into the two fourth connecting seats 500 respectively, thereby completing the assembly of the entire linkage door / window system. The entire installation process is simple and easy to understand, with low requirements for installers. The installation of the linkage door / window system can be achieved without complicated training for installers, which greatly reduces the time and labor costs of installation and improves installation efficiency.

[0058] In summary, the linkage module 100, linkage mechanism, and linkage door and window system disclosed in this utility model can bring at least the following beneficial technical effects:

[0059] (1) The linkage module 100 can be shipped as a whole. After shipment, the linkage module 100 can be directly installed on the second door and window sash 20. The whole installation process is simple and easy to understand, with low requirements for installers. The installation of the linkage door and window system can be achieved without complicated training for installers, which greatly reduces the time and labor costs of installation and improves installation efficiency.

[0060] (2) Installation can be completed by accurately inserting one of the first transmission components 33 into the corresponding slot or hole of the first door / window sash 10 and inserting the other first transmission component 33 into the corresponding slot or hole of the third door / window sash 30.
