[0071] like Figures 1 to 4 As shown, the armrest 1 of the present application includes a top plate 10, a front plate 11, a rear plate 12, a bottom plate assembly 13, an outer plate 15 and an inner plate 14. One end of the front plate 11 and one end of the rear plate 12 are respectively connected to the two ends of the top plate 10, and form a U-shaped frame with the top plate 10. The bottom plate assembly 13 is arranged relative to the top plate 10, and is connected to the other end of the front plate 11 and the other end of the rear plate 12. The bottom plate assembly 13 includes an opening 130, and the opening 130 is connected to the inside of the U-shaped frame. The outer plate 15 is arranged on one side of the top plate 10, the front plate 11, the rear plate 12 and the bottom plate assembly 13, and the inner plate 14 is arranged on the other side of the top plate 10, the front plate 11 and the rear plate 12, so that a cavity is formed inside the U-shaped frame. The top plate 10 , the front plate 11 , the back plate 12 , the outer plate 15 , the inner plate 14 and the bottom plate assembly 13 are made of wood materials of different strengths, such as plywood, solid wood or density board (MDF board) and the like.

[0072] The armrest 1 provided in the present application uses a bottom plate assembly 13 to form an opening 130, and is connected to a cavity composed of a top plate 10, a front plate 11, a rear plate 12, an outer plate 15 and an inner plate 14, so that the backrest 3 or the seat part 2 of the sofa can be loaded into the cavity of the armrest 1 during transportation, which can reduce the volume of the transportation package. The top plate 10, the front plate 11, the rear plate 12, the outer plate 15, the inner plate 14 and the bottom plate assembly 13 are all made of wood, avoiding the use of a metal frame, reducing weight and reducing costs. The armrest 1 with a cavity is formed by the bottom plate assembly 13 being connected to other plates of the armrest 1, and the overall strength of the armrest 1 can be improved. The wood material can be, for example, solid wood, artificial board, etc., as long as it contains wood but does not contain metal, such as pine, oak, beech, fiberboard, particleboard, plywood, density board (MDF board), etc. The materials of the top plate 10, the front plate 11, the back plate 12, the bottom plate assembly 13, the outer plate 15 and the inner plate 14 can be the same or different. The top plate 10 can be made of a density board (MDF board), the front plate 11 and the back plate 12 can be made of plywood, and the outer plate 15 and the inner plate 14 can be made of a density board (MDF board). The strength of solid wood is greater than that of plywood, and the strength of plywood is greater than that of density board (MDF board). The front plate 11 and the back plate 12 are roughly parallel, the top plate 10 and the bottom plate assembly 13 are roughly parallel, and the outer plate 15 and the inner plate 14 are roughly parallel.

[0073] In this embodiment, the bottom plate assembly 13 includes two first bottom plates 131 and two second bottom plates 132, wherein the two first bottom plates 131 are respectively sandwiched between the two ends of the two second bottom plates 132 to form an opening 130. The first bottom plate 131 includes a front first bottom plate 1311 and a rear first bottom plate 1312, wherein the front first bottom plate 1311 is connected to the surface of the front plate 11 facing the cavity, and the rear first bottom plate 1312 is connected to the surface of the rear plate 12 facing the cavity. The second bottom plate 132 includes an outer second bottom plate 1321 and an inner second bottom plate 1322, wherein the two ends of the outer second bottom plate 1321 are respectively connected to the front plate 11 and the rear plate 12, and one side of the outer second bottom plate 1321 is connected to the outer side plate 15; and the two ends of the inner second bottom plate 1322 are respectively connected to the front plate 11 and the rear plate 12. The projection width of the two second bottom plates 1321, 1322 on the top plate 10 is 10mm-30mm, preferably 15mm, which can ensure sufficient strength without affecting the size of the opening, so that the armrest can accommodate other structures of the sofa. The two first bottom plates 1311, 1312 and the inner second bottom plate 1322 can be made of plywood, and the outer second bottom plate 1321 can be made of solid wood, so that the outer side of the armrest is stronger.

[0074] In the present application, the bottom plate assembly 13 uses two pairs of first bottom plates 131 and second bottom plates 132 arranged opposite to each other, and the two first bottom plates 131 are respectively clamped at the two ends of the two second bottom plates 132 to form an opening 130, which can make the opening 130 large enough to facilitate the installation of larger parts such as the seat part or backrest of the sofa, which is conducive to simplifying the transportation packaging. The method of clamping the two first bottom plates 131 at the ends of the two second bottom plates 132 can improve the overall firmness and stability of the bottom plate assembly 13, improve the strength of the bottom plate assembly 13 and thus improve the strength of the armrest 1. The two first bottom plates 1311 and 1312 can be respectively formed by stacking at least two sub-plates, and a sub-plate away from the top plate 10 can be provided with a through hole, and a sub-plate close to the top plate 10 can be provided with a threaded hole; or both sub-plates can be provided with a threaded hole or a through hole. The number of sub-plates used in the two first bottom plates is the same. The more sub-plates there are, the higher the strength of the armrest is, and the more firmly and stably the armrest is fixed.

[0075] The height of the projection of the inner second bottom plate 1322 on the outer plate 15 is the same as the height of the projection of the two first bottom plates 1311 and 1312 on the outer plate 15, and both are greater than the height of the projection of the outer second bottom plate 1321 on the outer plate 15. This can achieve a more stable overall structure and save costs.

[0076] In this embodiment, the armrest 1 also includes a reinforcing plate 16 and a reinforcing plate 2 17, which are connected in an L shape and are both arranged relative to the outer plate 15. The reinforcing plate 16 is fixed to the surface of the inner plate 14 facing the outer plate 15, so that the reinforcing plate 2 17 is partially located between the inner plate 14 and the bottom plate assembly 13 to extend the cavity.

[0077] In the present application, a reinforcing plate 16 is provided on the inner surface of the inner side plate 14 near the rear plate 12, which can increase the strength of the inner side plate 14. A reinforcing plate 2 17 is provided at one end of the reinforcing plate 16 facing the bottom plate assembly 13, and the reinforcing plate 2 17 is connected to the reinforcing plate 1 16 in an L-shaped manner, so that the reinforcing plate 2 17 extends from the inner side plate 14 to the bottom plate assembly 13, thereby extending the cavity, making the cavity larger, and facilitating the storage and packaging of the sofa seat or backrest during transportation of the sofa. In addition, the reinforcing plate 2 17 can still enhance the strength of the armrest 1. The reinforcing plate 1 16 and the reinforcing plate 2 17 can both be made of wood material, which can be the same as the material of the top plate 10, the front plate 11, the rear plate 12, the bottom plate assembly 13, the outer side plate 15 and the inner side plate 14, or different. The material of the reinforcing plate 1 16 and the reinforcing plate 2 17 can be plywood, and the thickness of the board can be 10mm-30mm, preferably 15mm.

[0078] In this embodiment, the inner plate 14 is provided with a fixing hole 141 and a fixing hole 142, and the armrest 1 is connected to the backrest through the fixing hole 141 and the fixing hole 142. For example, a wedge-shaped slot can be used for connection. The inner plate 14 is provided with two fixing holes for connecting the backrest, which can make the connection between the armrest 1 and the backrest more tightly, improve the stability and reliability of the sofa, and better fix the positional relationship between the backrest and the armrest 1, thereby meeting the needs of users. The fixing hole 141 and the fixing hole 142 are through holes, and can be either a plain hole or a threaded hole.

[0079] In this embodiment, the reinforcing plate 16 is provided with a fixing hole 3 161, and the center line of the fixing hole 3 161 and the fixing hole 2 142 are on a straight line, and are used to connect the armrest 1 to the backrest. The fixing hole 3 161 provided on the reinforcing plate 16 and on the same center line as the fixing hole 2 142 is connected to the backrest, so that the backrest can be stably connected to the armrest 1, wherein the fixing hole 3 161 is generally a threaded hole.

[0080] In this embodiment, the armrest 1 further includes a reinforcing component 18, which is disposed in a portion of the cavity close to the top plate 10. The reinforcing component 18 is disposed in a portion of the armrest 1 close to the top plate 10, which can enhance the strength of the armrest near the top plate 10 without reducing the cavity inside the armrest and affecting the cavity capacity. A perfect balance between the capacity of the armrest cavity and the strength of the armrest is achieved.

[0081] In this embodiment, the reinforcement assembly 18 includes a reinforcement member 181 disposed in contact with the inner side plate 14, and a fixing hole 1811 is disposed at a portion of the reinforcement member 181 close to the reinforcement plate 16. The fixing hole 1811 is aligned with the center line of the fixing hole 141, and is used to connect the armrest 1 to the backrest. The reinforcement assembly 18 also includes at least one reinforcement member 182, and the reinforcement member 182 is disposed close to the outer side plate 15.

[0082] The reinforcement assembly 18 is designed to be separated, with a reinforcement member 181 and at least one reinforcement member 2 182, so that the packaging method during transportation can be more flexible, and a fixing hole 4 1811 is provided on the reinforcement member 181 for connecting the backrest, so that the backrest can be stably connected to the armrest 1, wherein the fixing hole 4 1811 is generally a threaded hole. The reinforcement member 2 182 is close to the outer plate 15, and can strengthen the strength of the junction between the outer plate 15 and the top plate 10, thereby improving the strength of the overall armrest.

[0083] The surface of the reinforcing member 181 facing away from the outer plate 15, the surface of the reinforcing plate 16 facing away from the outer plate 15, the surface of the reinforcing plate 2 17 facing away from the outer plate 15 and the surface of the inner second bottom plate 1322 facing away from the outer plate 15 are on the same plane. The above design can further improve the strength of the handrail, which is conducive to improving the connection strength of the handrail, making the handrail more stable and reliable after assembly.

[0084] The reinforcing plate 2 17 is provided with a fixing hole 5 171 and a fixing hole 6 172 for connecting the seat portion of the sofa. The bottom plate assembly 13 is also provided with a fixing hole 7 133 and a fixing hole 8 134 for connecting the armrest support of the sofa.

[0085] In this embodiment, at least one reinforcing plate three (not shown in the figure) is further provided on the surface of the front plate 11 facing the cavity and / or at least one reinforcing plate four 19 is provided on the surface of the rear plate 12 facing the cavity. Among them, reinforcing plate three and reinforcing plate four can be arranged approximately parallel to the bottom plate assembly, or approximately perpendicular to the bottom plate assembly, or inclined to the bottom plate assembly, or in all three of the above arrangement directions. Providing at least one reinforcing plate three and at least one reinforcing plate four 19 on the inner surface of the front plate 11 and / or the rear plate 12 can further enhance the strength of the front plate 11 and / or the rear plate 12, thereby improving the overall strength of the armrest 1. The number of reinforcing plate three and reinforcing plate four 19 can be one, two, or more than three, etc.

[0086] like Figures 5 to 7 As shown, the present application also provides a sofa, wherein the sofa comprises a seat portion 2, a backrest 3 and the above armrest 1, wherein the seat portion 2 and the backrest 3 are both segmented structures. With the segmented structure, the seat portion 2 or the backrest 3 can be loaded into the cavity of the armrest 1 during transportation packaging, thereby reducing the packaging volume and facilitating transportation.

[0087] The seat part 2 includes a first seat section 21 and a second seat section 22. This is only an example and is not divided into only two sections. It may also be divided into multiple sections according to the length of the sofa and the length of the sections. The wooden strips 23 are laid on the surface where the first seat section 21 and the second seat section 22 are connected. The seat legs 24 are arranged at the connection between the first seat section 21 and the second seat section 22 on the other surface. The seat legs 24 can also be arranged at other positions to only provide support.

[0088] The backrest 3 includes a first backrest section 31 and a second backrest section 32, similar to the seat portion 2. This is only an example, and is not divided into only two sections. It may also be divided into multiple sections according to the length of the sofa and the length of the sections. Moreover, the sections of the backrest 3 do not correspond to the sections of the seat portion 2 one by one, and can be staggered.

[0089] The sofa after installation can be seen Figure 7, wherein an armrest support leg 100 is arranged below the armrest 1, and the armrest support leg 100 is connected through a fixing hole 7 133 and a fixing hole 8 134 arranged on the bottom plate assembly 13 of the armrest 1. A front baffle 4 is also arranged at a front position below the sofa seat, wherein in this embodiment, the front baffle 4 is also a segmented structure, corresponding to the segments of the seat part 2 one by one, and in some other embodiments, the segments of the front baffle 4 may not correspond to the segments of the seat part 2.

[0090] It should be noted that the armrests and sofas shown in the drawings and described in this specification are only a few examples of the many types of armrests and sofas that can adopt the principles of the present application. It should be clearly understood that the principles of the present application are by no means limited to any details or any parts of the armrests and sofas shown in the drawings or described in this specification.

[0091] The above is a detailed description of several exemplary embodiments of the armrest and sofa proposed in the present application. The following is an exemplary description of the process of assembling the armrest proposed in the present application into a sofa.

[0092] Combined with Figures 1 to 7 The process of assembling the armrest into a sofa proposed in this application is: after the user receives the package, the seat part 2 and the backrest 3 of the sofa are taken out from the cavity of the armrest 1, and then the seat part 2 is fixed, and then the backrest 3 is fixed to the seat part 2, and then the armrest support foot 100 is connected to the armrest 1, and the armrest 1 is turned over, and the seat part 2 is fixedly connected through the reinforcing plate 17 of the armrest 1, and the backrest 3 is fixedly connected through the inner side plate 14 of the armrest 1.

[0093] Through the process of assembling the armrest of the present application into a sofa, it can be concluded that the armrest and sofa of the present application, by designing an armrest with a cavity, no metal frame is set in the armrest, and multiple wooden boards are fixed and connected according to certain rules, so that the cavity of the armrest is large enough and the strength is strong enough, avoiding the problems of using a metal frame, occupying the space of the cavity and being heavy, etc.

[0094] The armrest of the present application does not use a metal frame, but is still able to achieve the same strength as when a metal frame was used before. After a vertical impact force test, the armrest of the present application passed the impact test of 250 pounds (lbs) / 1112 Newtons (N) ≈ 113KG, achieving the same strength as when a metal frame was used before, and meeting the strength requirements of a sofa armrest, saving costs, saving space, being lightweight and having sufficient strength.

[0095] In summary, the armrest proposed in the present application is composed of wooden boards in a certain combination mode, including a top plate, a front plate, a back plate, a bottom plate assembly, an outer plate and an inner plate. One end of the front plate and one end of the back plate are respectively connected to the two ends of the top plate to form a U-shaped frame. The bottom plate assembly is arranged relative to the top plate and connected to the other end of the front plate and the other end of the back plate. The bottom plate assembly includes an opening, and the opening is connected to the inside of the U-shaped frame. The outer plate is arranged on one side of the top plate, the front plate, the back plate and the bottom plate assembly, and the inner plate is arranged on the other side of the top plate, the front plate and the back plate, so that a cavity is formed inside the U-shaped frame. The armrest with a cavity of the present application can accommodate other larger parts of the sofa into the cavity during transportation, which is conducive to reducing the size of the transportation packaging and reducing costs. The bottom plate assembly opening is adopted so that the armrest is open downward when the sofa is assembled, and no opening is provided on the top and the side, which can improve the strength of the overall armrest. No metal frame is used, which simplifies the processing technology, reduces weight and reduces costs.

[0096] The sofa proposed in the present application comprises a seat, a backrest and the above armrests, wherein the seat and the backrest are both segmented structures. The segmented structure enables the seat or the backrest to be loaded into the cavity of the armrest during transportation and packaging, thereby reducing the packaging volume, facilitating transportation, saving materials, and being energy-saving and environmentally friendly.
