The present disclosure relates to a technical field of household sofas, and in particular to a sofa being simple in assembly and disassembly and suitable for small dwelling-size apartment.
Sofas are one kind of software furniture provided with armrests respectively on both sides, and specifically belong to chairs having multiple seats with soft cushions and back chairs assembled with springs, thick foam plastic, etc. Nowadays, the sofas gradually become an essential household article in daily life.
A usable floor area in an apartment of each family is different. For some small dwelling-size apartment users, large-sized sofas may not be applicable for small dwelling-size apartments, and in daily life of the small dwelling-size apartment users, the sofas may be disassembled and stored when the sofas are not in use within a certain period of time. However, sofas applicable for the small dwelling-size apartments in the prior art generally fastened and assembled through screws, which is inconvenient to disassemble. In addition, there is no place to store assemblies of a disassembled sofa, which cannot meet storage standards of the small dwelling-size apartment users.
In order to solve problems that sofas applicable for the small dwelling-size apartments in the prior art are inconvenient to disassemble and store, the present disclosure provides a sofa being simple in assembly and disassembly and suitable for small dwelling-size apartment.
In order to achieve the above objectives, the present disclosure adopts following technical solutions.
The present disclosure provides a sofa, including a bottom box, two groups of wing-type armrests, a backrest, two groups of seat cushions, and two groups of backrest cushions.
The two groups of the wing-type armrests expand outward and are symmetrically connected to side walls of the bottom box. The backrest is connected to the two groups of the wing-type armrests. The two groups of the seat cushions are disposed on the bottom box. The two groups of the backrest cushions abut against the backrest. Bottom sides of the two groups of the backrest cushions abut against upper surfaces of the two groups of the seat cushions.
Furthermore, first clamping plates are fixedly connected to the two groups of the wing-type armrests. Second clamping plates are fixedly connected to the side walls of the bottom box. The second clamping plates are respectively clamped to the first clamping plates.
Furthermore, first clamping holes are defined on the first clamping plates. Second clamping holes are defined on the second clamping plates. The first clamping holes and the second clamping holes are the same in size. The first clamping holes include four groups of the first clamping holes and four groups of the second clamping holes. The four groups of the first clamping holes are symmetrically distributed on the first clamping plates. The four groups of the second clamping holes are symmetrically distributed on the second clamping plates.
Furthermore, third clamping plates are further fixedly connected to the two groups of the wing-type armrests. Fourth clamping plates are fixedly connected to the backrest. The third clamping plates are respectively clamped to the fourth clamping plates.
Furthermore, third clamping holes are defined on the third clamping plates. Fourth clamping holes are defined on the fourth clamping plates. The third clamping holes and the fourth clamping holes are the same in size. The third clamping holes include four groups of the third clamping holes and the fourth clamping holes include four groups of the fourth clamping holes. The four groups of the third clamping holes are symmetrically distributed on the third clamping plates. The four groups of the fourth clamping holes are symmetrically distributed on the fourth clamping plates.
In order to improve storage effect of the sofa, furthermore, storage bags are fixedly connected to the two groups of the wing-type armrests.
In order to improve overall stability of the sofa, furthermore, supporting seats are inserted into bottom sides of the two groups of the wing-type armrests. Inserting rods are fixedly connected to the supporting seats. Inserting holes are defined with respect to the inserting rods on the bottom sides of the two groups of the wing-type armrests.
In order to improve comfort for users after sitting down, furthermore, when the bottom sides of the two groups of the backrest cushions abut against the upper surfaces of the two groups of the seat cushions, an included angle formed by the two groups of backrest cushions and the two groups of the seat cushions is 105 degrees.
In order to increase a sitting depth of the sofa, furthermore, a length of each of the two groups of the seat cushions is 60 cm.
Optionally, seventy-two groups of bagged independent springs are disposed in the two groups of the seat cushions. Interiors of the two groups of the seat cushions are filled with high-density sponge. Snakelike springs are disposed in the bottom box, and high-elasticity bandages are wound on the snakelike springs.
Compared with the prior art, the present disclosure provides the sofa, which has following beneficial effects.
According to the sofa, the first clamping plates and the third clamping plates, disposed on the two groups of the wing-type armrests, are respectively clamped with the second clamping plates on the bottom box and the fourth clamping plates on the backrest. During assembly and disassembly, the assembly may be completed only by adopting bidirectional clamping rods, which is more convenient and faster in the assembly and the disassembly. According to the sofa of the present disclosure, sofa accessories, the backrest cushions, the seat cushions, and the two groups of the wing-type armrests may be stored in the bottom box, so that a usable floor area of a small dwelling-size apartment where the sofa configured is increased, and storing the sofa accessories through the bottom box is easier for transporting the sofa.
