Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The purpose of this embodiment is to provide a chair, which solves the problem of resource waste caused by the fact that a backrest and a support leg of the chair are independent in the prior art.

Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Referring to fig. 1-5, in the present embodiment, a chair includes a ring-like support 1 and a seat 2. The material of the ring-like support 1 can be solid wood, metal or plastic, the surface is a smooth arc surface, and the ring-like support is formed by bending the solid wood by a solid wood bending technology. As shown in fig. 1, the middle part of the similar annular support 1 is of a hollow structure, the seat 2 penetrates through the hollow part in the middle of the similar annular support 1 and is connected to the inner wall of the similar annular support 1, the front end and the rear end of the seat 2 are respectively located on two sides of the similar annular support 1, the bottom of the similar annular support 1 is provided with a first supporting point, the bottom of the seat 2 is provided with at least two second supporting points, the first supporting point and each second supporting point are in contact with the ground and are not overlapped, and the top end of the similar annular support 1 is higher than the bottom end of the similar annular support 1 and is higher than the top end of the seat 2. Alternatively, as shown in fig. 1, the surface of the seat 2 is also a rounded arc surface. It should be noted that the sizes of the chair can be set according to specific situations and specific requirements. The seat 2 itself has a certain height, for example, the height of the seat 2 is L1, L1 can be set to 400 mm and 450mm, specifically 407mm in the present scheme; the height of the ring-like support 1 is L2, L2 can be set to 700 and 800mm, and the height is 737mm in the scheme; the overall width of the chair is L3, L3 can be set to 700 and 800mm, and the overall width is 750mm in the scheme; the height of the ring-like support 1 corresponding to the position of the backrest is L4, and L4 can be set to be 140mm-180mm, in the scheme, the height is 160 mm. The top end of the similar annular support 1 is higher than the bottom of the similar annular support 1, so the similar annular support 1 is in a vertical state or an inclined state with a certain included angle with the ground, and the seat 2 penetrates through the similar annular support 1 and is connected to the inner wall of the similar annular support 1, and the second supporting point on the seat 2 is in contact with the ground, so that two parts of the seat 2, which are positioned at two sides of the similar annular support 1, are tilted by one end.
