[0040] As described in the background section, chairs, tables, cabinets, and beds on the market are currently individual items. These items are not interconnected and do not have any synergistic effect when used, resulting in inconvenience.

[0041] In view of this, an embodiment of the present invention provides a linkage structure that can solve the above problems. When this linkage structure is applied to chairs, tables, cabinets and beds, it can realize the linkage of opening and closing of chairs, tables, cabinets and beds in pairs, making them more convenient to use. It will be described in detail below.

[0042] Please refer to Figure 1 The linkage structure includes a first-side linkage pipe 1, a second-side linkage pipe 2, and a central common pipe 3. The second-side linkage pipe 2 and the first-side linkage pipe 1 are spaced apart. The central common pipe 3 is located between the first-side linkage pipe 1 and the second-side linkage pipe 2. The central common pipe 3 and the first-side linkage pipe 1 are intersected and rotatably connected. The central common pipe 3 and the second-side linkage pipe 2 are intersected and rotatably connected. This linkage structure can be applied to any two items in a chair, table, cabinet, or bed, allowing them to be linked together. This enables the simultaneous opening or closing of the two linked items, making them more convenient and improving the user experience. Furthermore, the linkage structure reduces the number of parts, lowers the overall weight, simplifies manufacturing, facilitates folding, occupies less space, and provides a better user experience.

[0043] The first side linkage pipe 1, the middle common pipe 3 and the second side linkage pipe 2 are rotatably connected together by a connecting component (such as a pin).

[0044] Optionally, a first-side reinforcing pipe 63 is provided between the first-side linkage pipe 1 and the intermediate common pipe 3. Both ends of the first-side reinforcing pipe 63 are connected to the first-side linkage pipe 1 and the intermediate common pipe 3, respectively, thereby increasing the connection reliability between the first-side linkage pipe 1 and the intermediate common pipe 3. A second-side reinforcing pipe 74 is provided between the second-side linkage pipe 2 and the intermediate common pipe 3, both ends of the second-side reinforcing pipe 74 are connected to the second-side linkage pipe 2 and the intermediate common pipe 3, thereby increasing the connection reliability between the second-side linkage pipe 2 and the intermediate common pipe 3. A sliding sleeve is connected to one end of both the first-side reinforcing pipe 63 and the second-side reinforcing pipe 74. The sliding sleeve on the first-side reinforcing pipe 63 is fitted onto the outside of the intermediate common pipe 3 and is slidable. The other end of the first-side reinforcing pipe 63 is rotatably connected to the first-side linkage pipe 1. The sliding sleeve on the second-side reinforcing pipe 74 is fitted onto the second-side linkage pipe 2 and is slidable. The other end of the second-side reinforcing pipe 74 is rotatably connected to the intermediate common pipe 3. The linkage structure also includes a first intermediate connecting seat 4 and a second intermediate connecting seat 5. The ends of the first side linkage pipe 1 and the second side linkage pipe 2 can be rotatably connected to the second intermediate connecting seat 5, and the end of the intermediate common pipe 3 can be rotatably connected to the first intermediate connecting seat 4.

[0045] The following explanation uses the linkage between a chair and a bed as an example. The linkage structure described above is applied between a chair and a bed to form a linkage between the two.

[0046] Continue to refer to Figures 1 to 4 The present invention also provides a combination bed and chair, including: a bed frame 6, a chair frame 7 and the above-mentioned linkage structure. The first side linkage pipe 1 serves as part of the bed frame 6, the second side linkage pipe 2 serves as part of the chair frame 7, and the middle common pipe 3 serves as part of both the bed frame 6 and the chair frame 7. The bed frame 6 and the chair frame 7 are linked together through the linkage structure.

[0047] The bed frame 6 also includes a first side folding tube group 61 and a first side edge support tube group 62, with two first side folding tube groups 61.

[0048] The first side folding tube assembly 61 includes two first side central intersecting tubes 611, which intersect and are rotatably connected. For example, they intersect and connect at the middle position of the two first side central intersecting tubes 611, and are rotatably connected together by connecting members (such as using pins or shafts). The two first side central intersecting tubes 611 can rotate relative to each other. The first side edge support tube assembly 62 includes two intersecting and rotatably connected edge support tubes 621, and the bottom end of each edge support tube 621 is connected to a first side hinge seat 622. In the first first-side folded tube group 61, the two ends of one first-side central cross tube 611 are rotatably connected to the middle common tube 3 and the corresponding first-side hinge seat 622, respectively; the two ends of the other first-side central cross tube 611 are rotatably connected to the corresponding edge support tube 621 and the second intermediate connecting seat 5, respectively. In the second first-side folded tube group 61, the two ends of one first-side central cross tube 611 are rotatably connected to the first-side linkage tube 1 and the corresponding first-side hinge seat 622, respectively; the two ends of the other first-side central cross tube 611 are rotatably connected to the corresponding edge support tube 621 and the first intermediate connecting seat 4, respectively.

[0049] Continue to refer to Figure 2 The chair support 7 is foldable or extendable. The chair support 7 includes a second side seat tube 70 and a second side backrest tube 71. The second side seat tube 70 is parallel to and spaced apart from the middle common tube 3. The second side backrest tube 71 is parallel to and spaced apart from the second side linkage tube 2. The bottom end of the second side seat tube 70 is connected to a seat-back connecting seat 732, and the bottom end of the second side backrest tube 71 is connected to a second side hinge seat 721.

[0050] A second-side support folding tube assembly 72 is provided between the second-side seat tube 70 and the middle common tube 3, and a second-side backrest folding tube assembly 73 is provided between the second-side backrest tube 71 and the second-side linkage tube 2, thereby realizing the folding and unfolding of the chair support 7.

[0051] The second-side support folding tube assembly 72 includes two second-side central intersecting tubes 722. The two second-side central intersecting tubes 722 intersect and are rotatably connected. For example, the middle parts of the two second-side central intersecting tubes 722 are connected and intersected. The two second-side central intersecting tubes 722 are connected together by connecting members (such as using pins or shafts) and are rotatable. The two ends of one second-side central intersecting tube 722 are respectively hinged to the second-side seat tube 70 and the second intermediate connecting seat 5, and the two ends of the other second-side central intersecting tube 722 are respectively hinged to the intermediate common tube 3 and the second-side hinge seat 721.

[0052] The second backrest folding tube assembly 73 includes two backrest cross tubes 731, which are intersecting and rotatably connected. For example, the two backrest cross tubes 731 are joined and intersected at the middle. The middle joint of the two backrest cross tubes 731 is connected together by a connecting component (such as a pin or dowel) and is rotatable. The two ends of one backrest cross tube 731 are respectively hinged to the second backrest tube 71 and the first intermediate connecting seat 4, and the two ends of the other backrest cross tube 731 are respectively hinged to the seat connecting seat 732 and the second side linkage tube 2.

[0053] In this embodiment, the first side linkage tube 1 is used as part of the bed frame 6 and the second side linkage tube 2 is used as part of the chair frame 7. The chair and the bed are linked together by the middle common tube 3. The two can be opened and folded together, which not only reduces the number of parts and the overall weight, but also makes the manufacturing simpler and the use more convenient.

[0054] When the extended combination bed and chair needs to be folded up, the first side linkage tube 1 and the middle common tube 3 can be rotated (or the second side linkage tube 2 and the middle common tube 3 can be rotated). The rotation of the first side linkage tube 1 and the middle common tube 3 (or the second side linkage tube 2 and the middle common tube 3) causes the first middle connecting seat 4 and the second middle connecting seat 5 to move closer together. The second side linkage tube 2 / first side linkage tube 1 is driven by the second middle connecting seat 5. At the same time, the movement of the second middle connecting seat 5 causes the first side folding tube assembly 61 and the second side support folding tube assembly 72 to fold. The side folding tube assembly 61 pulls and folds the first side edge support tube assembly 62, and the second side support folding tube assembly 72 pulls the second side seat tube 70 and the second side backrest tube 71 to achieve folding; the first intermediate connecting seat 4 moves and drives the backrest cross tube 731 hinged on it to rotate, thereby dragging the second side backrest tube 71 closer to the second side linkage tube 2 through the second side backrest folding tube assembly 73. Similarly, the second intermediate connecting seat 5 moves and drives the second side seat tube 70 closer to the middle common tube 3 through the second side support folding tube assembly 72, thereby realizing the folding of the combined bed and chair.

[0055] It is worth mentioning that in this embodiment, the middle common tube 3 serves as part of the bed frame 6 and part of the seat tube of the chair frame 7, and the second side linkage tube 2 serves as part of the backrest tube of the chair frame 7.

[0056] Optionally, the first side linkage pipe 1 can be formed by multiple branch pipes connected by hinge joints 8, thereby enabling folding or extension to reduce the volume after folding. Specifically, the ends of two adjacent branch pipes are respectively fixed with a hinge female head and a hinge male head, and the hinge female head and the hinge male head are hinged and can rotate.

[0057] Of course, the hinge joint 8 can also be applied to the edge support tube 621, the second side backrest tube 71 and the second side linkage tube 2 so that the overall bracket can be folded down to a smaller size.

[0058] An embodiment of this utility model also provides a combined table and chair, including: a table, a chair support 7 and the above-mentioned linkage structure. The table includes a first-side linkage tube 1, and the chair support 7 includes a second-side linkage tube 2. The table and the chair support 7 are linked together through the linkage structure.

[0059] An embodiment of this utility model also provides a combined chair cabinet, including: a cabinet frame, a chair support 7, and the above-mentioned linkage structure. The cabinet frame includes a first-side linkage pipe 1, and the chair support 7 includes a second-side linkage pipe 2. The cabinet frame and the chair support 7 are linked together through the linkage structure.

[0060] Of course, in other embodiments, the above-mentioned linkage structure can also be used between two chair supports 7 to form a combination of chairs, or between two bed supports 6, or between a bed support 6 and a cabinet, etc., which will not be listed here.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
