Description

Technical Field

[0001] This utility model relates to the field of rattan furniture technology, and in particular to a rattan chair with a support structure. Background Technology

[0002] As an important branch of traditional furniture, rattan chairs are widely used in indoor homes and outdoor leisure settings due to their natural and environmentally friendly material properties, unique woven textures, and good breathability.

[0003] The load-bearing structure of existing rattan chairs relies heavily on the weaving strength of the rattan itself, lacking effective mechanical support. When used for extended periods or under heavy loads, the center of the rattan cushion is prone to excessive indentation or even breakage, resulting in a shortened lifespan. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A rattan chair with a supporting structure includes:

[0006] A seat cushion assembly includes a rattan mat and fixing rods fixedly disposed at both ends of the rattan mat;

[0007] Two sets of parallel support frames, each with a through hole adapted to a fixing rod at the top position inside the support frame, and a through groove adapted to a rattan mat inside the support frame on one side of the through hole.

[0008] An elastic support frame is connected between the two sets of support frames, and the top of the elastic support frame supports the middle part of the rattan mat.

[0009] As an improvement to the above technical solution, the cross-section of the elastic support frame is an arc-shaped structure, and multiple sets of through holes are opened on the elastic support frame.

[0010] As an improvement to the above technical solution, annular spring pieces are fixedly sleeved on the surface of the fixing rod at both ends, and a limiting groove adapted to the annular spring pieces is opened inside the support frame on one side of the through hole.

[0011] As an improvement to the above technical solution, a rubber pad is bonded to the surface of the annular spring.

[0012] As an improvement to the above technical solution, a cushion is also included, which is placed between the ends of the two sets of support frames.

[0013] The beneficial effects of this utility model are:

[0014] By connecting the fixing rod to the through hole of the support frame and the edge of the rattan mat to the through groove, a rigid support frame is formed, which effectively avoids the displacement of the seat cushion components during use, ensures the overall structure of the chair is stable, and provides users with a safe and reliable user experience.

[0015] When a person sits down, the elastic support frame generates an upward restoring force through compression deformation. Working in conjunction with the rattan mat, it effectively distributes the pressure on the body, reduces excessive deformation in the middle of the rattan mat, and avoids local pressure concentration. After the person gets up or moves, the elastic support frame can quickly restore its deformation, causing the rattan mat to return to its original position. This reduces the risk of damage to the rattan mat caused by continuous deformation and extends the overall lifespan of the chair. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0021] A rattan chair with a supporting structure includes:

[0022] The cushion assembly includes a rattan mat 21 and fixing rods 20 fixedly disposed at both ends of the rattan mat 21;

[0023] Two sets of parallel support frames 10, each support frame 10 having a through hole 11 adapted to the fixing rod 20 inside and at the top position, and a through groove 12 adapted to the rattan mat 21 inside and on one side of the through hole 11.

[0024] An elastic support frame 30 is connected between the two sets of support frames 10, and the top of the elastic support frame 30 supports the middle part of the rattan mat 21.

[0025] Specifically, the fixing rod 20 is inserted into the through hole 11 of the support frame, and the edge of the rattan mat 21 is embedded in the through groove 12 to form a stable frame structure. When a person sits on the rattan mat 21, the middle part of the rattan mat 21 is depressed downward due to the weight of the person. At this time, the elastic support frame 30 will be compressed and compressed. It generates an upward restoring force through its own elastic deformation, which supports the rattan mat 21, reduces the excessive deformation of the rattan mat 21, avoids excessive local pressure, and provides elastic cushioning to improve the comfort of sitting. When the person moves or gets up, the elastic support frame 30 restores its deformation and drives the rattan mat 21 to return to its original position, maintaining the structural stability and reusability of the chair. The connection between the fixing rod 20 and the through hole 11 makes it easy to disassemble and replace the rattan mat 21.

[0026] In one embodiment, the elastic support frame 30 has a circular arc-shaped cross-section and multiple sets of through holes. The top arc surface of the circular arc frame naturally fits the curved surface of the middle part of the rattan mat 21. When the rattan mat 21 is concave downward, the contact area of ​​each point of the circular arc frame gradually increases, forming a "progressive support". When initially subjected to force, the top of the arc contacts first, and as the pressure increases, the middle section and both sides of the arc surface participate in the support in turn, avoiding local stress concentration. The through holes reduce the weight and promote air circulation under the rattan mat 21, which is in line with the breathability of the rattan mat 21.

[0027] In one embodiment, annular spring pieces 22 are fixedly sleeved on the surface of the fixing rod 20 at both ends. A limiting groove adapted to the annular spring piece 22 is provided inside the support frame 10 on one side of the through hole. When the fixing rod 20 is inserted into the through hole, the annular spring piece 22 will be squeezed inward because its outer diameter is larger than the diameter of the through hole. When the annular spring piece 22 moves to the position of the limiting groove, the elastic restoring force causes its outer edge to be stuck in the limiting groove, thus completing the locking. After the annular spring piece 22 is stuck in the limiting groove, it generates a radially outward thrust, which tightly fixes the fixing rod 20 in the through hole 11, preventing the fixing rod 20 from moving axially.

[0028] In one embodiment, a rubber pad is bonded to the surface of the annular spring 22. The annular spring 22 and the limiting groove may wear out due to long-term insertion and removal. The rubber pad serves as an intermediate buffer layer, effectively isolating the contact surface, reducing wear, and improving the durability of the structure.

[0029] In one embodiment, a backrest is also included, which is fixedly disposed between the ends of the two sets of support frames. The backrest provides effective support for the user's back, relieves fatigue from prolonged sitting, helps maintain good posture, reduces spinal pressure, and improves comfort and health. The backrest is made of rattan.
