The present disclosure relates to the field of furniture, in particular to a foldable armrest, a sofa and a single chair.
At present, the transportation costs surge, especially the ocean freight of export products stays at a high level, so how to increase the container loading capacity and reduce the ocean freight has become an urgent problem for the industry to solve. A sofa or single chair, as an article commonly used in people's work and life, belongs to oversized furniture. However, armrests of a sofa or single chair in the prior art are usually of an integrated fixed connection structure, and occupy too much space. Usually, it is of a fixed structure, which has a large packaging volume and small container loading capacity, such that a large quantity of human and material resources are necessary during transportation, and consumed time is long. Very large space is also necessary during storage, such that storage and transportation costs are increased. A width of each of the existing sofa armrests may not be adjusted, and is available in only one size, which may not meet the requirements of users.
In order to solve the above technical problem, prior art has disclosed a sofa armrest frame convenient to fold and a sofa. The sofa armrest frame includes two articulated top plates; a first side plate articulated to one side of one top plate; a second side plate articulated to one side of the other top plate; two sets of first limiting parts arranged on the first side plate and the second side plate respectively; and two supporting plates provided with second limiting parts mated with the first limiting parts on two sides of the two supporting plates.
In view of the defects in the prior art, the present disclosure aims to provide foldable armrests, a sofa and a single chair, which are used for solving the problems that existing commercial transportation space is large, costs are high, a container loading capacity is small, and a width of each of armrests may not be adjusted according to actual requirements of users.
In order to achieve the above objectives and other relevant objectives, the present disclosure provides a foldable armrest, including armrest body. The foldable armrest is wherein the armrest body includes an outer side plate and an inner side plate which may be folded in a width direction of the armrest body; a width adjusting mechanism is connected between the outer side plate and the inner side plate; the width adjusting mechanism includes locking kits and at least one adjusting rod; the locking kits are connected with the inner side plate, the adjusting rods are connected with the outer side plate, and the locking kits and the adjusting rods are interlocked in the width direction of the armrest body; and when the outer side plate and the inner side plate move away from each other in the width direction of the armrest body, the width adjusting mechanism extends in the width direction of the armrest body, and when the outer side plate and the inner side plate move closer to each other in the width direction of the armrest body, the width adjusting mechanism retracts in the width direction of the armrest body.
Preferably, each of the locking kits includes a connecting part and a locking sleeve, the connecting part is connected to one side of the inner side plate facing the outer side plate, and the locking sleeve detachably penetrates into the connecting part.

It is ensured that the outer side plate and the inner side plate are well supported, and meanwhile the armrest covers are tightened, such that the appearance is kept flat.
Each of the armrest covers of the present disclosure may be of the fully-detachable or the semi-detachable structure, and the supporting plates are convenient to detach and install since the armrest cover is of the detachable structure. The detached armrest cover may be washed and subjected to vacuum compression packaging, which is conducive to transportation. Due to the folding and unfolding structure of the armrests, the wide armrests may be compressed into a small-size package, in addition, soft packages, such as a seat cushion and a backrest cushion, may be detached and subjected to vacuum compression packaging, the volume is small, and the high container loading capacity is achieved. The width adjusting mechanism is of an extensible gear structure, such that different widths of the armrests may be achieved according to requirements. It is convenient for customers to assemble, they may read an instruction book or watch an assembly video, thereby ensuring that the customers may rapidly assemble the sofa or single chair.
The present disclosure has the beneficial effects that the widths of the armrests can be adjusted according to requirements, so as to save transportation space and costs and increase the container loading capacity; the widths can also be adjusted according to the actual requirements of the users, such that the requirements of different users are met; and the whole structure is convenient to adjust and attractive in appearance.
