Demountable chair

Abstract

The invention relates to the technical field of furniture and particularly relates to a demountable chair. The demountable chair consists of a chair body, a seat supporting frame and chair legs, wherein the chair body comprises a seat which is used for undertaking the hip-thigh part of a human body, the upside of the seat supporting frame can be detached from the seat, the downside of the seat supporting frame can be detached from the chair legs, the seat supporting frame comprises a load bearing frame, which is provided with a flat upper surface and is formed through interconnecting four hollow metallic tubes, and supporting bodies which are fixed to the lower surface of the load bearing frame and are used for being connected with the chair legs, the four hollow metallic tubes are of an arc concave shape towards the center of the load bearing frame, the concave hollow metallic tubes are in end-to-end connection sequentially, and structures that adjacent hollow metallic tubes are abutted with one another by sidewalls are formed at junctions; the upper ends, in the vertical direction, of the supporting bodies are welded to the lower surfaces of the bottom walls, adjacent to abutted sidewalls, of adjacent hollow metallic tubes. The demountable chair has the advantages of simple and firm structure, strong carrying capacity, difficulty in deformation, convenience in production, convenience in demounting and low cost.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a detachable seat. Background technique [0002] The most important function of the seat is to facilitate people to rest, and to enable users to sit in a comfortable sitting posture. A properly designed seat main support structure directly affects the quality, cost, portability, and service life of the seat. [0003] According to "A Preliminary Study on the Interpretation of Ancient Books", the chair originated in the Wei, Jin and Sui dynasties of our country. In the Song and Yuan dynasties, a commonly used seat appeared, called Hu bed, also known as Maza. Hu bed is easy to carry, but its There is no support in the middle of the cushion part, and the cushion will be obviously sunken after sitting down, and sitting for a long time will lead to deformation of the sitting posture, which will affect the user's health and experience. [0004] Similar to the support structure of th...

Problems solved by technology

However, this structure also has the problem that the support is not stable enough, and the cushion will sag towards the middle over time

Patent 00813517.7 provides a technical solution to solve the problem of support and depression on the previous basis, but its structure is relatively complex, costly and heavy

[0006] Appearance patent 201330232826.7 discloses a chair support structure, which adopts a welding structure of arc-shaped metal pipes similar to this patent on the load-bearing frame of the chair cushion. The side walls of the inner recess of the arc-shaped stainless steel pipe are welded to each other, and the welding point is located in the middle of the support surface. This structure is simple and can better prevent the cushion from sinking in the middle, but whether the pipes welded to each other is solid directly affects the cost and welding value of the structure. , the welding structure of the stainless steel pipe is not considered to be strengthened, so the structural strength of the welding is limited, and its detachability is also not considered, and the side area of ​​the cushion that deviates from the center area of ​​the cushion is easily deformed
