Description

Technical Field

[0001] The utility model relates to the technical field of office chair manufacturing, in particular to a novel office chair with a double U-shaped chair back frame and an armrest integrated into one. Background Art

[0002] Office chairs refer to various chairs that are used for the convenience of work in daily work and social activities. There are many types of office chairs. Common office chairs are mostly traditional office chairs with separate armrests and trays. With the continuous improvement of people's living standards, consumers are more discerning and have high requirements for product design. How to break through the traditional office chair shape, achieve innovative design and more prominent functions is what furniture companies need to consider.

[0003] The invention disclosed in application number CN202311608836.5 particularly relates to an office chair. An office chair with strong practicality is provided, including an office chair, a fixing frame, a first fixing rod, an adjustment mechanism and a support mechanism. The office chair is placed on the ground, the front side of the office chair is connected to the first fixing rod, the upper side of the first fixing rod is connected to the fixing frame, the first fixing rod is provided with an adjustment mechanism for adjusting the hanging height of clothes, and the adjustment mechanism is provided with a support mechanism for preventing clothes from wrinkling. The invention adjusts the hanging height of clothes by the up and down movement of the first movable rod, so that different styles and lengths can be hung appropriately. Although this invention adjusts the length of the first movable rod by the inward and outward movement of the threaded rod, thereby achieving a better placement and fixing effect, preventing clothes from wrinkling, and thus obtaining strong practicality, the overall structure of this invention cannot realize the integrated structure of the chair back and armrests.

[0004] For example, the utility model disclosed in application number CN202222774140.X proposes a backrest and armrest linkage office chair, which relates to the technical field of backrest and armrest linkage office chairs, including a seat back and a seat armrest installed on the seat back, the seat back and the seat armrest are rotatably connected, and a reset member for resetting the seat armrest is provided between the seat armrest and the seat back. Although this type of backrest and armrest linkage office chair does not have a connecting structure between the seat armrest and the seat cushion, which expands the activity space of the seat armrest, the overall shape of the chair is not simple enough, and the front and rear structure of the seat is relatively wide.

[0005] Another example is the utility model disclosed in application number CN202322687722.6, a double-back office chair, which belongs to the technical field of office chairs. It includes a chair leg, a seat, and a chair back. The bottom of the seat is connected to a chair back bracket. The chair back includes two spaced-apart unit chair backs. The lower part of the unit chair back is elastically swingingly connected to the chair back bracket. The chair back bracket is provided with a chair back angle limiting structure that matches the upper part of the unit chair back. Although the utility model can effectively support the user's office sitting posture and avoid the user's back fatigue, the chair back and the seat of this utility model cannot achieve an integrated structure.

[0006] In response to the above common problems of office chairs, we can combine the current market demand and independently develop a new type of office chair with a double U-shaped chair back frame and armrests. The innovatively designed double U-shaped frame breaks the shape of traditional office chairs and designs a new type of office chair that is both beautiful and functional and practical.

The double U-shaped frame is composed of an upper U-shaped frame, a lower U-shaped frame, and a support rod. The upper U-shaped frame and the lower U-shaped frame are fixed by the support rod, and the support rod is fixed at the middle position of the upper U-shaped frame and the lower U-shaped frame. The lower U-shaped frame is provided with a plurality of locking pieces for fixing the seat. The seat is semi-elliptical, which is the same as the lower part of the chair back. The upper U-shaped frame is fixed to the outer back of the chair back, and the lower U-shaped frame is fixed to the bottom of the seat. The double U-shaped frame fixes the seat and the chair back to each other. The lower part of the chair is composed of a bottom tray, a gas rod, a chair foot, and a chair wheel. The bottom tray is fixed to the bottom of the seat, the upper end of the gas rod is fixed in the round hole of the bottom tray, and the lower end is fixed in the middle hole of the chair foot, and the bottom of the chair foot is fixed with a chair wheel.

[0009] As a preferred embodiment of the above technical solution, the bottom of the chair back is fixed by a zipper.

[0010] As a preferred embodiment of the above technical solution, the bottom locking piece of the seat is fixed by bolts.

[0011] As a preferred embodiment of the above technical solution, a gas rod decorative cover may be covered on the outside of the gas rod.
