Description

Technical Field

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

[0002] Conventional sofas consist of components such as left and right armrests, back frame, and seat frame, which are cumbersome to assemble and expensive. This solution provides a convenient assembly sofa structure and corresponding connection structures to simplify the assembly process. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a sofa structure that solves the problem of complex assembly of existing sofas.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sofa structure, including a frame and a crossbar, wherein the crossbar includes a back frame crossbar and a seat frame crossbar, and a seat back is provided between the back frame crossbar and the seat frame crossbar, wherein the seat back is made of soft fabric.

[0005] By adopting the above technical solution, there is no need for a traditional back frame and seat frame. The frame can be directly assembled with crossbars and seat back to form a sofa structure, which simplifies the product structure, makes it easy to assemble and reduces costs.

[0006] Furthermore, one end of the seat back is connected to the back frame crossbar and the other end is connected to the seat frame crossbar, forming an arc-shaped structure between the two crossbars.

[0007] By adopting the above technical solutions, the seat back structure conforms to ergonomic design, improving product comfort.

[0008] Furthermore, the seat back includes a plurality of spaced-apart fabric units, each of which is a long strip of soft fabric.

[0009] By adopting the above technical solution, the volume of the seat and backrest can be reduced without affecting the intended use of the sofa, making it easier to transport.

[0010] Furthermore, the frame includes two symmetrically arranged side frames, and each crossbar is fixed by the two side frames.

[0011] By adopting the above technical solution, the two symmetrically arranged side frames are easier to disassemble and transport compared to the integral frame structure.

[0012] Furthermore, the top of the side frame is provided with an extension end, which is inclined upwards and outwards from the bottom of the sofa.

[0013] By adopting the above technical solution, stable support is provided for the inclined installation of the back frame crossbar.

[0014] Furthermore, the back frame crossbar is fixed to the extension end and is inclined along the extension end.

[0015] By adopting the above technical solution, the sofa is more ergonomic and comfortable to use. The seat and backrest are matched with the back frame crossbar that is inclined to the outside and upward of the sofa. The connection is smooth and the stress is relatively small, reducing wear and tear.

[0016] Furthermore, the end of the seat is provided with a covering structure and connected to the crossbar through a fixing structure. The covering structure is formed by wrapping the end of a soft fabric around the surface of the crossbar.

[0017] By adopting the above technical solution, the covering structure forms a larger contact surface between the seat and the crossbar to ensure connection strength.

[0018] Furthermore, the fixing structure includes an assembly groove and a fastener, with the assembly groove disposed on the crossbar.

[0019] By adopting the above technical solution, the pre-reserved assembly slot is used to position and fix the fasteners, reducing the difficulty of installation.

[0020] Furthermore, the fixing structure also includes a fixing strip, and the end of the seat is provided with a ring that is fixed to the fixing strip. The fixing strip is sleeved inside the ring, and the fixing member passes through the fixing strip sleeved with the ring to fix the seat to the crossbar.

[0021] By adopting the above technical solution, the fixing strip has better strength than the soft fabric structure. Compared with the method of the fixing member directly passing through the soft fabric, the fixing strip is placed on the loop formed by the soft fabric, and then the fixing member passes through the soft fabric and the fixing strip. The soft fabric is not easy to pull, and the risk of damage due to stress during long-term use is lower, so as to ensure the connection strength.

[0022] Furthermore, the fixing strip is made of a flexible, soft plastic material.

[0023] By adopting the above technical solution, the fixing structure has a certain tension under the elastic action of the fixing strip, making the connection tighter.

[0024] Furthermore, the end of the seat is fixed to the crossbar by a fixing structure, the fixing structure including an assembly groove and a fixing strip, the end of the seat is provided with a ring sleeve fixed to the fixing strip, the fixing strip is sleeved in the ring sleeve and fixed to the crossbar by snapping into the assembly groove.

[0025] By adopting the above technical solution, the pins of the fasteners are eliminated, and the seat and crossbar are fixed by inserting the fixing strip into the ring and into the assembly groove, which simplifies the assembly difficulty.

[0026] Compared with the prior art, the advantages of this utility model are: 1. Simplifying the sofa components and reducing the difficulty of disassembly and assembly; 2. Each component occupies little space and is easy to transport; 3. The arc-shaped soft seat back formed by the soft fabric structure provides high comfort; 4. Multiple connection methods enable a stable connection between the seat back and the crossbar. Attached Figure Description
