Description

Technical Field

[0001] This application relates to the field of soft furnishing technology, and in particular to a sofa with detachable armrests. Background Technology

[0002] A sofa is a multi-seat chair with cushions, usually with armrests on both sides. The frame is typically made of wood or steel, and the interior is lined with cotton or other foam materials, making it generally comfortable. Nowadays, sofas have become a common type of upholstered furniture.

[0003] Currently, sofas generally consist of a seat, armrests, and a backrest. Furthermore, existing sofas are categorized based on the armrests: sofas with non-removable armrests and sofas with removable armrests.

[0004] Regarding the aforementioned technologies, the inventors believe that in commonly used sofas with detachable armrests, the disassembly process is too cumbersome, inconvenient for customers, and affects their user experience. Utility Model Content

[0005] The purpose of this application is to provide a sofa with detachable armrests to improve the problem of inconvenient removal of detachable armrests.

[0006] This application provides a sofa with detachable armrests, employing the following technical solution:

[0007] A sofa with detachable armrests includes a sofa body comprising a base and a backrest. A first mounting plate is provided on each of the two side walls of the base, and a second mounting plate is provided on each of the two side walls of the base at the lower end of the first mounting plate. An armrest is provided on the side of the first mounting plate away from the base. A sliding mounting assembly is provided between the armrest and the first and second mounting plates. The sliding mounting assembly includes a guide rail and a sliding rail. The guide rail is provided on the side wall of the first and second mounting plates that is in contact with the armrest. The sliding rail is provided on the side wall of the armrest and slides in cooperation with the corresponding sliding rail. A fixed mounting assembly is provided between the backrest and the armrest. The mounting assembly includes a first fixed plate and a second fixed plate. The first fixed plate is located at the end of the backrest (12) and has a through-hole. The second fixed plate can be inserted into the through-hole to fix the armrest.

[0008] By adopting the above technical solution, when the handrail needs to be installed, the handrail can be quickly installed through the cooperation of the guide plate and the sliding rail; the second fixing plate is inserted into the fixing hole to fix the handrail; thus achieving the purpose of easy disassembly of the handrail.

[0009] Optionally, a fastening plate is rotatably provided at the end of the second fixing plate away from the handrail.

[0010] By adopting the above technical solution, and by rotating the fastening plate on the second fixing plate, the fastening plate and the second fixing plate can be made to fit together, achieving a better fixing effect.

[0011] Optionally, the fastening plate is fitted with a fixing bolt that is threadedly connected to the first fixing plate.

[0012] By adopting the above technical solution, the armrest is slidably installed onto the sofa and its position is fixed. The fastening plate is then threadedly connected to the first fixing plate using fixing bolts.

[0013] Optionally, the nut of the fixing bolt is provided with an anti-slip extension plate.

[0014] By adopting the above technical solution, an anti-slip extension plate is installed at the nut of the fixing bolt, allowing for manual disassembly and assembly of the handrail, which facilitates customer operation and improves the customer's user experience.

[0015] Optionally, the sliding plate has several mounting grooves on both sides, and rollers are rotatably mounted on the inner sidewall of the mounting grooves, with the rollers fitting against the inner sidewall of the guide rail plate.

[0016] By adopting the above technical solution, mounting grooves are provided on both sides of the guide rail plate, and rollers that fit against the inner sidewall of the guide rail plate are installed on the inner sidewall of the mounting groove, so as to facilitate the sliding of the handrail into the guide rail plate.

[0017] Optionally, the outer wall of the roller is provided with a rubber layer.

[0018] By adopting the above technical solution, a rubber layer is set on the outside of the roller to increase the fit between the sliding rail and the guide plate, so that the armrest can be installed on the sofa more quietly and smoothly, and the armrest can be fixed more stably on both sides of the sofa; at the same time, the stability of the armrest is improved.

[0019] Optionally, the side wall of the armrest facing the base is provided with a plurality of receiving grooves, and a support leg is rotatably provided on the inner side wall of the receiving groove, and the support leg can be located inside the receiving groove by rotation.

[0020] By adopting the above technical solution and by setting up a receiving groove and supporting legs, the armrest can be transformed into a stool that can be used by people by rotating and extending the supporting legs after disassembly.

[0021] Optionally, a rubber pad is provided on the inner sidewall of the receiving groove and the end that abuts against the support leg after it is spread open.

[0022] By adopting the above technical solution, a rubber pad is provided at the end of the inner wall of the receiving groove that abuts against the support leg after it is spread out, which restricts the support leg from rotating outward and provides more force-bearing area for the support leg when the armrest is converted into a stool.

[0023] Optionally, the side wall of the armrest facing the base is provided with a shielding layer that covers the receiving groove.

[0024] By adopting the above technical solution, Velcro is provided along the edge of the receiving groove on the side wall of the armrest facing the base; the covering layer is made of fabric, and Velcro is provided on the edge of the fabric; when the armrest is installed on both sides of the sofa, the covering layer is attached to make the armrest more beautiful and improve the customer's user experience.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The mounting plate, sliding mounting components, and fixed mounting components ensure the armrests are positioned on both sides of the sofa, facilitating disassembly and assembly and improving the customer's user experience;

[0027] 2. By incorporating receiving slots, support legs, and rubber pads into the armrests, they can be transformed into stools when necessary, increasing product value and enhancing the customer experience;

[0028] 3. A covering layer is provided on the side of the armrest where the receiving groove is set. When the armrest is installed on both sides of the sofa, it is used to cover the receiving groove, improve the product's appearance, and enhance the customer's user experience.
