Embodiment 1

[0045] The chair comprises a seat 1, a chair back 2, a chair foot 4 and a pneumatic rod 11, the seat 1 and the chair back 2 are connected by hexagon socket head screws 17, and the chair leg 4 and the seat 1 are connected by a pneumatic rod 11 The chair seat 1, chair back 2 and chair foot 4 are all made of extruded aluminum alloy profiles. The interior of the seat is divided into inner cavity A and inner cavity B, and the inner cavity located on the lower side A and the inner cavity B on the upper side are separated by a rib structure, the section of the inner cavity A is a triangular structure, and the section of the inner cavity B is an inverted triangle structure. The three sides of the triangle, that is, the rib structure, have been optimized and artistically designed, which not only enhances the stability, but also has an aesthetic feeling. At the same time, it makes the extruded aluminum profile easy to form when extruded. The pneumatic rod 11 is protected when it explode...

Abstract

The invention discloses a chair which comprises a seat, a chair back and chair legs, wherein the seat is connected with the chair back; the chair legs are connected with the seat by virtue of a pneumatic rod; the seat, the chair back and the chair legs are made of extrusion aluminum alloy profiles; the interior of the seat is divided into an inner cavity A and an inner cavity B; the inner cavity A positioned on the lower side is separated from the inner cavity B positioned on the upper side by virtue of rib structures; the section of the inner cavity A is of a triangular structure; the section of the inner cavity B is of an inverted triangular structure; a cavity structure is formed in the lower part of the chair back; and multiple cavity structures are formed inside the chair legs. The closed inner cavities, closed curved cavities and local closed cavities on the appearances of the sections of the aluminum alloy profiles are subjected to optimization design, so that a hollow engraving artistic effect is achieved. Meanwhile, special service functions are designed on the sections of exposed profiles, and the sections of the optimized profiles are effectively combined with the service functions.

Description

technical field [0001] The invention relates to the technical field of structural design and application of chairs. Background technique [0002] Traditional chairs are not highly deformable, and their strength is not high, and they are easily deformed after long-term use. [0003] People are eager to obtain a chair with excellent technical effect. Contents of the invention [0004] The object of the present invention is to provide a chair with excellent technical effect. [0005] The chair includes a seat, a back and feet, the seat and the back are connected, and the feet and the seat are connected by a pneumatic rod, and the seat, the back and the feet are all made of extruded aluminum alloy The inside of the seat is divided into an inner cavity A and an inner cavity B. The inner cavity A on the lower side and the inner cavity B on the upper side are separated by a rib structure. The inner cavity A The cross-section is a triangular structure, and the cross-section of ...
