Description

a chair

technical field

The invention relates to the field of office equipment, in particular to a chair.

Background technique

Nowadays, there are more and more white-collar workers, and many people are almost facing the computer when they work during the day, sitting all day, so many young people now have lumbar disc herniation, cervical spondylosis, etc.;

The method advocated by most people, including doctors, is to be able to correct the sitting posture, but in the actual correction process, it is difficult. When going to work, it can be corrected in time, but as the work progresses, the lumbar spine will gradually collapse, and then Continue to form a burden on the lumbar spine, so there is no good solution to this problem until now;

In addition, the current chair function is too single to meet more needs; for example, the chair is too hard, and there is no sense of integration when sitting down, making users feel uncomfortable.

Contents of the invention

Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a more comfortable chair that protects the user's lumbar spine, assists in correction.

In order to achieve the above object, the technical scheme adopted in the present invention is:

A chair comprising:

The supporting part is used to support the user's seated buttocks;

The chair legs are rod-shaped parts installed around the bottom of the support part to support the weight of the whole chair and the user;

a backrest mounted on one side of the support or on the side of the foot below that side;

Folding board, which consists of several boards connected in series, and the boards can rotate around the connection between themselves and adjacent boards, the side of the bottom board is fixed on the upper surface of the support part, and the side of the top board is slidably installed on the On the backrest, a jacking device is installed under the foldable plate to lift the foldable plate to make it protrude outward;

The support part is viewed as a rectangle from above, and the number of chair legs is four, which are vertically installed at the four corners below the support part; a single chair leg is divided into upper, middle and lower sections, and the two ends of the middle section are set in the bottom of the upper section and the top of the lower section , and the two ends of the middle section are fixedly connected with the upper section and the lower section with hydraulic cylinders or springs. This structure allows the user to sit down with a slight cushion. More comfort.

The setting of the folding board is based on fundamentally changing the concept of correction at the current stage. Now most people are forced to correct, forcing themselves to correct consciously, and this effect is obviously not good. Then, we need to help users slow down. Adapt slowly to prolong the process of adaptation. First let the user maintain the current bad habit, but increase the protection of the lumbar spine under this bad habit, and then adjust the lifting degree of the jacking device to make the user adjust to normal. state, reduce the user's psychological burden, protect the user's lumbar spine, and help to correct.

As a preferred solution of the present invention, the folding board is composed of two boards connected in series, which has a simple structure, facilitates processing, reduces costs, and can meet the minimum use requirements of the chair of the present application.

As a preferred solution of the present invention, memory foam is laid on the outer surface of the folding board. Among users with herniated lumbar discs, the shape of each person's spine is different. Most people have a slight S-shaped curvature, but use a chair to help During the correction process, the shape of the spine will be corrected slowly, and this process needs to continuously ensure that the folding plate adapts to the shape of the spine at any stage, so the use of memory foam perfectly adapts to the above situation.

As a preferred solution of the present invention, the jacking device is a plurality of hydraulic rods, the structure is simple, and the cost is reduced. At the same time, the hydraulic rod technology is very mature, and the quality controllability of the chair is higher by using the hydraulic rod.

As a preferred solution of the present invention, there are two hydraulic rods, parallel to each other, the lower ends are installed on the connection between the support part and the backrest, and the upper ends are installed on the same series connection of the folding plates, and act on the same series connection at the same time, so that In the process of the folding plate protruding outward, the user experience is better, the force wrapped on both sides of the spine is more symmetrical, and the correction effect is better.

As a preferred solution of the present invention, the connection positions where the upper ends of the two hydraulic rods are connected in series with the folding plate are symmetrically located on both sides of the vertical symmetrical midline of the folding plate, and the structure is symmetrical and more stable.

As a preferred solution of the present invention, the hydraulic rod can be remotely operated by a remote control device, and the user can change the lifting amount of the jacking device according to the needs to suit his own situation.

The beneficial effects of the present invention are:

Protect the user's lumbar spine, help correction, and make it more comfortable.
