Description

An adjustable reclining chair

technical field

The invention relates to the technical field of seats, in particular to an adjustable reclining and sitting integrated chair.

Background technique

Functionally convertible design has very important practical significance for present and future life. In today's increasingly compact pace of life, whether it is study, work or leisure and entertainment, no matter where you are from the company unit to the swimming pool or the beach, people are always inseparable from the need for "lying", especially after busy work. There is a strong urge to lie down and relax.

After having a demand, the corresponding problem also emerged. The simple action of lying down cannot be satisfied anytime and anywhere. Currently widely used recliners, folding beds and other functional convertible furniture are too large in size. Due to some special human or environmental factors, most of the reclining chairs, folding beds, multi-functional sofas and other functional conversions are too large. Such products may not be able to play a role; especially in some public areas such as dense office buildings, laboratories and some leisure places, if you want to meet the needs of lying, you must be inseparable from reclining chairs, folding beds and other products.

Take the office as an example. Most of the offices are located in commercial office buildings. There are many people and few places in the building. The personal space of each worker is mostly very limited. Therefore, the most common rest state during lunch break or overtime is to lie on the table or stretch your legs and lean up between the tables and chairs. Even if you want to use products such as reclining chairs and folding beds, it is not easy. According to research, the most common recliners and folding beds need to occupy at least two square meters, and they can easily function in large office spaces, but it becomes a problem to replace them in dense office areas. Small space, high crowd density, safety restrictions and other issues have caused most of the lying rest products to be inconvenient to use, leaving most workers in an embarrassing situation where they cannot take a good rest after being tired.

Based on the fact that seats with convertible functions in the prior art are generally large-scale and large-scale designs, there is no specific design that can meet the conditions of small activity range, small space use, office furniture shape, fire safety regulations, etc. Small size and easy to use standard. Lying down at this time seems to be a luxury.

Contents of the invention

Aiming at the defects in the prior art, the present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the object of the present invention is to propose an adjustable reclining and sitting integrated chair; the use mode can be adjusted according to needs, and its specific technical scheme is as follows:

An adjustable reclining integrated chair, comprising a support board, a backrest assembly connected to the support board, and a conversion assembly; the conversion assembly includes a pair of front support legs and a pair of rear support legs; two ends of the front support legs Curved arrangement, the front support legs are rotatably arranged on both sides of the front end of the support plate, the two ends of the rear support legs are arranged in a bend, and the rear support legs are rotatably arranged on both sides of the rear end of the support plate The backrest assembly includes a lower backing plate connected to the hinge at the rear end of the support plate, the lower backing plate is hinged with adjustment rods on both sides corresponding to the two rear support legs, and the adjustment rods can be snapped into the top of the rear support legs in the adjustment card slot.
