Technical Field
[0001] This utility model belongs to the field of furniture technology and relates to a sofa chair, particularly a rope-woven backrest structure for a sofa chair. Background Technology
[0002] Existing sofas and chairs, especially metal sofas and chairs suitable for outdoor use, mostly use castings or aluminum parts as the main frame, and their backrests are mostly composed of metal rods, which are rigid and have poor comfort. In addition, some existing metal backrests have backrests made of plastic rattan, but these are still prone to wear and tear. In particular, when the plastic rattan is woven and wrapped around the metal backrest frame, the protruding tubing not only affects the flatness of the backrest frame surface, but also makes it very easy to wear off, causing the seat to peel off in parts, affecting both aesthetics and comfort. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a rope-woven backrest structure for a sofa chair.
[0004] The objective of this utility model can be achieved through the following technical solution: A braided chair back structure for a sofa chair, comprising a chair back frame and a winding rope, characterized in that the chair back frame comprises a top frame rod, an upper winding rod, a lower winding rod, and a bottom frame rod arranged from top to bottom; the top frame rod and the upper winding rod are spaced apart, and an upper threading frame for inserting the winding rope is formed between them; the lower winding rod and the bottom frame rod are spaced apart, and a lower threading frame for inserting the winding rope is formed between them; the upper winding rod and the lower winding rod are spaced apart, and they are connected by a support column; the winding rope is alternately wound around the upper winding rod and the lower winding rod in sequence.
[0005] In the aforementioned braided backrest structure of the sofa chair, the loops formed by the winding ropes wound around the upper and lower winding rods are spaced apart from one end to the other along the axial direction of the upper and lower winding rods.
[0006] In the aforementioned braided backrest structure of the sofa chair, there are two symmetrically arranged support columns, and the two support columns are located on both sides of each rope loop formed by the winding rope on the upper winding rod and the lower winding rod, respectively.
[0007] In the aforementioned braided backrest structure of the sofa chair, the top frame rod and the upper winding rod are arranged parallel to each other, and the lower winding rod and the bottom frame rod are arranged parallel to each other.
[0008] In the aforementioned braided backrest structure of the sofa chair, the end of the top frame rod and the corresponding end of the upper winding rod are connected together by an upper connector, and the end of the lower winding rod and the corresponding end of the bottom frame rod are connected together by a lower connector.
[0009] In the aforementioned braided backrest structure of the sofa chair, the top frame rod, the upper winding rod, and the upper connector are integrally cast and molded as a single structure, and the lower winding rod, the bottom frame rod, and the lower connector are integrally cast and molded as a single structure.
[0010] In the aforementioned braided backrest structure of the sofa chair, the winding rope is an elastic rope.
[0011] Compared with the prior art, the present invention has the following advantages:
[0012] 1. This utility model uses a winding rope as the backrest component of the chair back, which is elastic and provides good backrest comfort.
[0013] 2. In this utility model, the winding rope is wound around the frame formed by the upper winding rod and the lower winding rod, and is located inside the frame formed by the top frame rod and the bottom frame rod, respectively. This can prevent the winding rope from protruding from the top and bottom surfaces of the chair back frame, thus avoiding breakage caused by wear. At the same time, since the winding rope is not wound around the top and bottom frame rods, the flatness, aesthetics, and comfort when using the chair back frame are ensured. Attached Figure Description

[0015] Figure 2 This is a schematic diagram of the structure of this utility model.
[0016] In the diagram, 1 is the winding rope; 2 is the top frame rod; 3 is the upper winding rod; 4 is the lower winding rod; 5 is the bottom frame rod; 6 is the upper connector; 7 is the lower connector; and 8 is the support column. Detailed Implementation
[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0018] Reference Figure 1 and Figure 2This embodiment is a braided chair back structure for a sofa chair, including a chair back frame and a winding rope 1. The chair back frame includes a top frame rod 2, an upper winding rod 3, a lower winding rod 4, and a bottom frame rod 5 arranged from top to bottom. The top frame rod 2 and the upper winding rod 3 are spaced apart and arranged parallel to each other. The ends of the top frame rod 2 and the corresponding ends of the upper winding rod 3 are connected to an upper connector 6. The top frame rod 2, the upper winding rod 3, and the two upper connectors 6 at their common ends form an upper threading point for inserting the winding rope 1. The frame, lower winding rod 4, and bottom frame rod 5 are spaced apart. The ends of the lower winding rod 4 and the corresponding ends of the bottom frame rod 5 are connected to a lower connector 7. The lower winding rod 4 and the bottom frame rod 5 are arranged parallel to each other. The ends of the lower winding rod 4, the bottom frame rod 5, and the two lower connectors 7 at their common ends form a lower threading frame for inserting the winding rope 1. The upper winding rod 3 and the lower winding rod 4 are spaced apart and connected by a support column 8. The winding rope 1 is alternately wound around the upper winding rod 3 and the lower winding rod 4. In this embodiment, the two ends of the winding rope 1 can be knotted and fixed to the upper winding rod 3, the lower winding rod 4, or itself.
[0019] Furthermore, in this embodiment, the loops formed by the winding rope 1 wound around the upper winding rod 3 and the lower winding rod 4 are spaced apart from one end to the other along the axial direction of the upper winding rod 3 and the lower winding rod 4. The undulations of each loop are basically consistent with those of the upper winding rod 3 and the lower winding rod 4, which makes the front wall surface formed by the loops relatively smooth and provides good comfort.
[0020] Furthermore, the support columns 8 are arranged symmetrically, and the rope loop formed by the winding rope 1 wrapped around the upper winding rod 3 and the lower winding rod 4 covers the support columns 8, which can visually cover the support columns 8 and improve the aesthetics.
[0021] Furthermore, the top frame rod 2, the upper winding rod 3, and the upper connector 6 are integrally cast structures, as are the lower winding rod 4, the bottom frame rod 5, and the lower connector 7. The molding process for each component is relatively simple, and they occupy a small volume during disassembly, assembly, and transportation.
[0022] Furthermore, the winding rope 1 is an elastic rope, and the back of the chair formed by the winding rope 1 is elastic, providing good comfort.
[0023] Furthermore, the diameter of the winding rope 1 is 0.5-1.5cm, which can avoid the winding rope 1 from protruding too much after being wound due to the diameter being too large, and can also avoid the discomfort caused when leaning back due to the diameter being too small.
[0024] In this embodiment, the winding rope 1 is wound around the frame formed by the upper winding rod 3 and the lower winding rod 4, and is located inside the frame formed by the top frame rod 2 and the bottom frame rod 5, respectively. This can prevent the winding rope 1 from protruding from the top and bottom surfaces of the chair back frame, thus avoiding breakage caused by wear. At the same time, since the winding rope 1 is not wound around the top frame rod 2 and the bottom frame rod 5, the flatness, aesthetics, and comfort when using the chair back frame are better ensured.
[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
