Chair structure

Abstract

This invention relates to a chair structure, which mainly involves extending the rear end of the seating section upward to form a backrest assembly section. The chair legs are assembled and fixed with the leg assembly holes at the bottom of the seating section. The backrest or cover can be selected and fixed to the backrest assembly section of the seating section according to different usage needs. This not only reduces the space occupied before assembly, facilitating storage and transportation, but also provides excellent visual aesthetics after assembly, increasing the overall product value. Furthermore, the backrest and cover can be replaced according to different usage needs, and different leg shapes can be formed by locking the leg assembly holes at the bottom of the seating section, thus enhancing the overall practicality and functionality of the chair.

Claims

1. A chair structure, mainly comprising a seating area, chair legs, a backrest, and a cover; wherein: The seating section has a backrest assembly section extending upwards at its rear end. Corresponding locking grooves are recessed on both sides of the backrest assembly section, and a connecting hole is formed at the upper end of the backrest assembly section. Several leg assembly holes are formed at the bottom end of the seating section. The legs are assembled and fixed to the leg assembly holes at the bottom end of the seating section. The backrest is assembled and fixed to the backrest assembly section of the seating section. A locking block is protruding from the backrest end, corresponding to the locking grooves on both sides of the backrest assembly section, and a connecting part is also provided at the backrest end, corresponding to the connecting hole formed at the upper end of the backrest assembly section. This connecting part allows for assembly and fixing using a connecting component. The cover has locking blocks on both sides that are recessed into the locking grooves on both sides of the backrest assembly section, and a cover assembly part is provided in the middle of the cover corresponding to the assembly through hole formed at the upper end of the backrest assembly section. The cover assembly part can be assembled and fixed by the cover assembly part and the assembly through hole. This allows the backrest assembly section of the seating part to be assembled with the backrest, and also allows the backrest assembly section to be assembled with the cover when the backrest is not in use.

2. The chair structure as described in claim 1, wherein, The chair back extends forward on both sides to form armrests.

3. The chair structure as described in claim 1, wherein, The chair legs are respectively provided with an upper fixed section and a lower fixed section. The upper fixed section forms an upper mounting hole for the seating part that can be assembled and fixed with the mounting hole of the chair leg. The upper fixed section has a first support foot extending downward from both ends. The lower fixed section has a groove formed in the middle of the upper fixed section that can be recessed and fixed with the mounting hole of the chair leg. When the lower fixed section and the upper fixed section are assembled and fixed at the bottom of the seating part in a cross shape, the middle of the upper fixed section is precisely placed in the groove of the lower fixed section. The lower fixed section also has a second support foot extending downward from both ends. The first support foot and the second support foot are supported on the ground at the same time.

4. The chair structure as described in claim 1, wherein, The chair leg is equipped with a mounting plate, and the mounting plate has a mounting hole for the seat part that can be assembled and fixed. At the bottom of the mounting plate, a gas spring connects to a movable wheel, which can be used to slide and move on the ground.
