[0001] This utility model relates to the field of living furniture technology, and in particular to a folding chair. Background Technology

[0002] With the accelerating pace of urbanization and increasing population density, the efficiency of public and private space utilization has become a focus of social attention. In this era where land is extremely valuable, how to efficiently utilize limited space resources has become an urgent problem to be solved. Traditional seating, whether sofas and dining chairs in homes or seats in public places, still occupies a certain amount of space when not in use. This not only makes the limited space resources underutilized, but is also particularly inconvenient when users need to carry or move them, making it difficult to meet the needs of diverse scenarios such as outdoor activities, impromptu gatherings, and mobile offices.

[0003] Furthermore, with the diversification of lifestyles, people's needs for seating are constantly changing. The fixed shape and single function of traditional seating can no longer meet modern people's pursuit of flexibility and multifunctionality. For example, during outdoor activities, people want lightweight chairs that are easy to carry; during family gatherings, they want to be able to quickly add seats without taking up too much space; and in small living environments, they want to save space while maintaining comfort and aesthetics.

[0004] Therefore, there is a need to develop a foldable seat to improve the space utilization efficiency and portability of traditional seats.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0053] The folding seat provided in this embodiment adopts a rotating connection structure between the upright plate assembly 1 and the seating cross plate 2, realizing the folding and storage of the seat. Each vertical plate of the upright plate assembly 1 can be rotated to a stacked state where the thickness direction coincides, thereby greatly reducing the volume of the seat. This folding design allows the seat to be folded and stored in a small space when not in use, greatly improving space utilization efficiency. The folding structure also facilitates the carrying and transportation of the seat, meeting the needs of portability.

[0054] Therefore, the folding seat provided by this utility model can effectively improve the space utilization efficiency and portability of traditional seats through the design of the folding structure.

[0055] In this embodiment, there are three vertical uprights, with the middle one being the middle upright 101. The riding crossboard 2 is rotatably connected to the middle upright 101. When the upright assembly 1 is in the unfolded state, the three vertical uprights form a U-shaped structure surrounding the riding crossboard 2.

[0056] Specifically, the vertical plate located on one side of the intermediate plate 101 is the first side plate 102, and the vertical plate located on the other side of the intermediate plate 101 is the second side plate 103.

[0057] A narrow-edge transition plate 104 is provided between the first side upright plate 102 and the middle upright plate 101. One side of the narrow-edge transition plate 104 is hinged to the middle upright plate 101, and the other side is hinged to the first side upright plate 102.

[0058] A wide-edge transition plate 105 is provided between the second side upright plate 103 and the middle upright plate 101. One side of the wide-edge transition plate 105 is hinged to the middle upright plate 101, and the other side is hinged to the second side upright plate 103.

[0059] Wherein, the width of the wide-side transition plate 105 is greater than the width of the narrow-side transition plate 104, such that:

[0060] When the upright plate assembly 1 is rotated to the stacked state, the first side upright plate 102 is attached to the side of the riding cross plate 2 facing away from the middle upright plate 101, and the second side upright plate 103 is attached to the side of the first side upright plate 102 facing away from the middle upright plate 101.

[0061] That is, when folding and storing, after rotating the first side upright plate 102 to fit against the middle upright plate 101 on the side facing away from the seat cross plate 2, the seat cross plate 2 needs to be rotated to a vertical position first, and then the second side upright plate 103 is rotated to fit against the seat cross plate 2 on the side facing away from the middle upright plate 101. The second side upright plate 103 and the middle upright plate 101 cooperate to clamp the middle seat cross plate 2, preventing the middle seat cross plate 2 from accidentally rotating downward to a horizontal position.

[0062] It should be noted that when in the unfolded state, the middle upright panel 101 is mainly used as a backrest, while the side upright panels serve as armrests. In some other embodiments, only one side upright panel may be provided, or no side upright panels may be provided at all.

[0063] Optionally, the bottom of the middle upright plate 101 is provided with casters 106, and the bottom of both side upright plates is provided with support feet 107.

[0064] In this embodiment, the intermediate upright plate 101 includes an upright plate body 1011 connecting the two transition plates, and a reinforcing plate 1012 fitted to the lower part of the upright plate body 1011 and rotatably connected to the riding cross plate 2 via a support frame.

[0065] Furthermore, the reinforcing plate 1012 and the seating crossbar 2 are rotatably connected within a range of 0-90° via a rotation limiter 3. Optionally, the rotation limiter 3 can be a 90° limiting rotating hinge, a foldable triangular bracket, a 90° limiting door hinge, etc.

[0066] When the upright panel assembly 1 is in the stacked state, the side of the riding cross panel 2 away from the upright panel body 1011 is flush with the side of the reinforcing plate 1012 away from the upright panel body 1011, so as to improve the fit between the second side upright panel 103 and the riding cross panel 2 in the folded state and reduce abnormal noise caused by insufficient fit between the panels during movement.

[0067] Optionally, an L-shaped airbag 4 is fixedly connected to the upper part of the upright body 1011 and the seating crossbar 2. Further, the seating crossbar 2 is also connected to an inflation / deflation pump 5 for inflating / deflating the L-shaped airbag 4. The inflation / deflation pump 5 is installed at the end of the seating crossbar 2 such that when the upright assembly 1 is in the stacked state, the inflation / deflation pump 5 is higher than each of the vertical uprights.

[0068] See Figure 4 In this embodiment, the middle upright plate 101 has a U-shaped groove 1011a on the side facing away from the riding cross plate 2. A rotating handle 6 with 180° rotation limit is rotatably installed in the U-shaped groove 1011a. The rotating handle 6 has a hidden state where it can be rotated into the U-shaped groove 1011a, and a use state where it can be rotated to a height above the middle upright plate 101.

[0069] The folding chair provided in this embodiment is used as follows:

[0070] (1) When it is necessary to unfold the device from its folded state for use

[0071] First, rotate the middle upright plate 101, the first side upright plate 102, and the second side upright plate 103 from the stacked state to the U-shaped unfolded state;
