The transmission wheel is mounted on a pulley assembly connected to the linkage fan body and is used to mount the transmission bar. One end of the transmission clamp is connected to the pulley assembly connected to the movable fan body, and the other end of the transmission clamp is connected to the transmission bar. The transmission bar includes two transmission parts, and a transmission cavity is formed between adjacent hanging rail units. The transmission clamp connects to the transmission parts through the transmission cavity, and the two ends of the two transmission parts extend downwards into the transmission cavity to connect and form a transmission closed loop. In this solution, the transmission parts of the linkage structure are located inside the transmission cavity, allowing the transmission clamp to directly connect to the transmission parts through the transmission cavity, avoiding the need for the transmission clamp to be inserted into the gap between the hanging rail unit and the fan body to achieve the transmission connection between two adjacent fan bodies.

Description

Technical Field

[0001] This invention belongs to the technical field of door and window hardware, and particularly relates to a linkage structure and its linkage door and window. Background Technology

[0002] Multi-link sliding doors and windows are a common type of door and window system. They generally consist of two movable sashes and several linked sashes. Each sash is equipped with a corresponding hanging rail pulley structure, and multiple sashes can be opened or closed simultaneously through a special linkage structure.

[0003] The existing linkage structure requires connecting the two hanging rail pulley assemblies by passing through the joint between the hanging rail profile and the fan body profile. This method inevitably results in a gap between the hanging rail and the fan body, which is not aesthetically pleasing. Summary of the Invention

[0004] The purpose of this invention is to provide a linkage structure that allows for transmission between two adjacent fan bodies without requiring the gap between the hanging rail unit and the fan body.

[0005] The first aspect of the present invention discloses a linkage structure for installation within a hanging rail pulley structure to drive and link the movable sash and the linked sash of a door or window. The hanging rail pulley structure includes a hanging rail unit and a pulley assembly. The linkage structure includes a transmission bar, a transmission wheel, and a transmission clamp. The transmission wheel is disposed on the pulley assembly connected to the linked sash and is used to mount the transmission bar. One end of the transmission clamp is connected to the pulley assembly connected to the movable sash, and the other end of the transmission clamp is connected to the transmission bar. The transmission bar includes two transmission parts, which are disposed on both sides of the hanging rail unit along the length direction of the pulley assembly. The transmission directions of the two transmission parts are opposite. A transmission cavity is formed between adjacent hanging rail units. The transmission clamp connects the transmission parts through the transmission cavity. The two ends of the two transmission parts extend downwards from the transmission cavity and are connected to form a closed-loop transmission.

[0006] Optionally, the transmission bar further includes two connecting portions, which are located at the extended ends of the transmission portions and are used to connect the two transmission portions. The connecting portions are tractively connected to the transmission wheel at the bottom of the pulley assembly along the width direction of the pulley assembly.

[0007] Optionally, the transmission bar further includes four steering portions, which are disposed between the transmission portion and the connecting portion along the height direction of the pulley assembly, for connecting the transmission portion inside the transmission cavity to the connecting portion outside the transmission cavity.

[0008] Optionally, the transmission bar is a cylindrical steel wire.

[0009] Optionally, the transmission wheel includes a first transmission wheel and a second transmission wheel. The first transmission wheel is connected to both sides of the pulley assembly and is used to guide the two transmission parts. The connection between the transmission part and the steering part is sleeved on the first transmission wheel. The second transmission wheel is connected to the bottom of the pulley assembly and is used to guide the two steering parts. The connection between the steering part and the connecting part is sleeved on the second transmission wheel.

[0010] Optionally, the pulley assembly includes a side pulley bracket and an end pulley bracket. The side pulley brackets are located on both sides of the transmission bar. The end pulley brackets are located at both ends of the pulley assembly and between the two side pulley brackets. The first transmission wheel is fixed to the outside of the side pulley bracket, and the second transmission wheel is fixed to the outside of the end pulley bracket.

[0011] Optionally, the linked door / window includes multiple linked sashes, and the transmission clamp includes:

[0012] A movable fan drive clamp, one end of which is connected to the pulley assembly connected to the movable fan body, and the other end of which is connected to the drive bar on the adjacent pulley assembly connected to the linkage fan body;

[0013] A linkage fan drive clamp, one end of which is connected to the pulley assembly connected to the linkage fan body, and the other end of which is connected to the drive bar on the adjacent pulley assembly connected to the linkage fan.

[0014] Optionally, one of the linked fan drives is clamped at the first end of one of the pulley assemblies, and the other adjacent linked fan drive is clamped at the second end of another pulley assembly.

[0015] Optionally, the transmission clamp includes a fixed base and a clamping part. The fixed base is fixed to the pulley assembly. One end of the clamping part is connected to the fixed base, and the other end of the clamping part extends from one of the hanging rail units into another hanging rail unit along a direction parallel to the width of the pulley assembly and is connected to the transmission bar.

[0016] The second aspect of the present invention discloses a linkage door and window, comprising: two movable sashes, a plurality of linkage sashes, a plurality of hanging rail pulley structures, and the aforementioned linkage structure. The hanging rail pulley structure includes a hanging rail unit and a pulley assembly. The hanging rail pulley structure is used to slidably connect the movable sashes or the linkage sashes. The linkage structure is used to be installed in the hanging rail pulley structure to drive the movable sashes and linkage sashes of the linkage door and window.

[0017] The beneficial effects of this invention are as follows:

[0018] In this design, the transmission unit of the linkage structure is located within the transmission cavity, allowing the transmission clamp to directly connect to the transmission unit through the cavity. This avoids the need for the transmission clamp to be inserted into the gap between the hanging rail unit and the sash body to achieve the transmission connection between two adjacent sash bodies. Since the linkage structure and the sash body are not directly related in this design, the linkage structure and the hanging rail pulley structure can be pre-installed, reducing on-site sash body installation steps, resulting in an aesthetically pleasing appearance and convenient installation.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

For those skilled in the art, the specific meaning of the terms in this invention can be understood according to the specific circumstances.

[0032] See Figure 1 This solution discloses a linkage door and window, including two movable sashes 200, several linkage sashes 300, multiple hanging rail pulley structures, and a linkage structure 30. The hanging rail pulley structure includes a hanging rail unit 10 and a pulley assembly 20. The hanging rail pulley structure is used to slide and connect the movable sashes 200 or the linkage sashes 300. The linkage structure 30 is installed in the hanging rail pulley structure to drive the movable sashes 200 and the linkage sashes 300 of the linkage door and window.

[0033] See Figure 2-4 The linkage structure 30 includes a transmission bar 31, a transmission wheel 32, and a transmission clamp 33. The transmission wheel 32 is mounted on a pulley assembly 20 connected to the linkage fan body 300 and is used to mount the transmission bar 31. One end of the transmission clamp 33 is connected to the pulley assembly 20 connected to the movable fan body 200, and the other end of the transmission clamp 33 is connected to the transmission bar 31.

[0034] See Figure 4 The transmission bar 31 includes two transmission parts 311. The transmission parts 311 are arranged on both sides of the hanging rail unit 10 along the length direction of the pulley assembly 20. The transmission directions of the two transmission parts 311 are opposite. A transmission cavity 101 is formed between adjacent hanging rail units 10. The transmission clamp 33 is connected to the transmission parts 311 through the transmission cavity 101. The two ends of the two transmission parts 311 extend downward into the transmission cavity 101 and are connected to form a transmission closed loop.

[0035] In this design, the transmission part 311 of the linkage structure 30 is located within the transmission cavity 101, allowing the transmission clamp 33 to directly connect to the transmission part 311 through the transmission cavity 101. This avoids the need for the transmission clamp 33 to be inserted into the gap between the hanging rail unit 10 and the sash body to achieve the transmission connection between two adjacent sash bodies. Since the linkage structure and the sash body are not directly related in this design, the linkage structure and the hanging rail pulley structure can be pre-installed, reducing the on-site sash body installation steps, resulting in an aesthetically pleasing appearance and convenient installation.

[0036] In this embodiment, the transmission bar 31 further includes two connecting portions 312 and four steering portions 313. The connecting portions 312 are located at the extended ends of the transmission portions 311 and are used to connect the two transmission portions 311. The connecting portions 312 are connected to the transmission wheel 32 at the bottom of the pulley assembly 20 along the width direction of the pulley assembly 20. The steering portions 313 are located between the transmission portions 311 and the connecting portions 312 along the height direction of the pulley assembly 20 and are used to connect the transmission portions 311 inside the transmission cavity 101 to the connecting portions 312 outside the transmission cavity 101. The connecting portions 312 and the steering portions 313 form a U-shaped structure, which can avoid the hanging rail structure opened in the middle and also minimize the space occupied by the transmission belt, without increasing the area occupied by the pulley assembly 20.

[0037] The transmission bar 31 is a cylindrical steel bar, which can satisfy continuous, firm and stable transmission in three directions: transmission part 311, connecting part 312 and steering part 313.

[0038] In this embodiment, the transmission wheel 32 includes a first transmission wheel 321 and a second transmission wheel 322. The first transmission wheel 321 is connected to both sides of the pulley assembly 20 and is used to guide the two transmission parts 311. The connection between the transmission part 311 and the steering part 313 is sleeved on the first transmission wheel 321. The second transmission wheel 322 is connected to the bottom of the pulley assembly 20 and is used to guide the two steering parts 313. The connection between the steering part 313 and the connecting part 312 is sleeved on the second transmission wheel 322. The cooperation of the first transmission wheel 321 and the second transmission wheel 322 realizes the stable reversal and transmission of the transmission bar 31 in three directions.

[0039] In this embodiment, the pulley assembly 20 includes side pulley brackets 2121 and end pulley brackets 2122. The side pulley brackets 2121 are located on both sides of the transmission bar 31; the end pulley brackets 2122 are located at both ends of the pulley assembly 20 and between the two side pulley brackets 2121. The first transmission wheel 321 is fixed to the outside of the side pulley bracket 2121 to extend into the transmission cavity 101, without occupying extra space. The second transmission wheel 322 is fixed to the outer end of the end pulley bracket 2122. Since the pulley bracket slides on the hanging rail unit 10, and the pulley bracket itself reserves a certain gap with the end of the hanging rail unit 10 after installation, the second transmission wheel 322 also does not occupy extra space, which helps to simplify the linkage structure 30.

[0040] In this embodiment, the linkage door and window is a four-linkage sliding window, including two linkage sashes 300 and two movable sashes 200. The transmission clamp 33 includes a movable sash transmission clamp 3301 and a linkage sash transmission clamp 3302. One end of the movable sash transmission clamp 3301 is connected to the pulley assembly 20 connected to the movable sash 200, and the other end is connected to the transmission bar 31 on the adjacent pulley assembly 20 connected to the linkage sash 300. One end of the linkage sash transmission clamp 3302 is connected to the pulley assembly 20 connected to the linkage sash 300, and the other end is connected to the transmission bar 31 on the adjacent pulley assembly 20 connected to the linkage sash. Each linkage sash 300 is provided with a closed-loop transmission bar 31. The linkage between two adjacent linkage sashes 300 is transmitted through the linkage sash transmission clamp 3302, and the linkage between the movable sash 200 and the linkage sash 300 is transmitted through the movable sash transmission clamp 3301.

[0041] In this embodiment, one linkage fan drive clamp 3302 is disposed at the first end of a pulley assembly 20, and another adjacent linkage fan drive clamp 3302 is disposed at the second end of another pulley assembly 20, wherein the first end and the second end are opposite in direction, and are the two ends of the pulley assembly 20, respectively. This is understandable. The transmission parts 311 of two adjacent transmission bars 31 move in opposite directions, and disposing of the two linkage fan drive clamps 3302 at the two ends of the pulley assembly 20 respectively helps to lengthen the linkage movement distance between the two linkage fans.

[0042] Specifically, the transmission clamp 33 includes a fixed base portion 331 and a clamping portion 332. The fixed base portion 331 is fixed to the pulley assembly 20. One end of the clamping portion 332 is connected to the fixed base portion 331, and the other end of the clamping portion 332 extends from one hanging rail unit 10 into another hanging rail unit 10 along a direction parallel to the width of the pulley assembly 20 and is connected to the transmission bar 31. The transmission clamp 33 is positioned with the shortest distance parallel to the width of the pulley assembly 20, which facilitates better linkage with the transmission bar 31.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
