[0002] Folding chairs are a type of seating product that can shrink in size through a folding structure. They are widely used in various scenarios such as home leisure, outdoor camping, temporary office use, and sports event spectator seating. Their core feature is that they can be folded to reduce the space occupied when not in use, making them convenient to store and move, saving storage space for users, and making them easy to carry to different places of use to meet diverse usage needs.

[0003] Existing folding chairs typically only accommodate one user at a time. In scenarios where multiple people are together, such as family outdoor picnics, short-distance camping trips, or gatherings with friends, multiple single folding chairs need to be carried to meet the seating needs of multiple people. This not only increases the overall quantity and weight of equipment and the burden of carrying it, but also occupies more storage space (such as car trunks, storage backpacks, etc.), resulting in a significant decrease in travel convenience.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please refer to Figures 1-5 This utility model discloses a folding chair that is easy to store, including four supporting columns 1, front and rear side columns 14, a multi-person seat cushion 2, and side armrests 32. The four supporting columns 1 and the center columns 14 form the support legs of the folding chair, used to support the overall structure. The multi-person seat cushion 2 is the core component for users to sit on, and can be made of fabric with a certain degree of elasticity and breathability to improve seating comfort. The armrests 32 provide support for the user's hands, making it easier for the user to maintain a comfortable sitting posture, while also enhancing the stability of the folding chair during use. The top of the supporting columns 1 is equipped with... Mounting column 3 is an installation structure used to install other structures. The two rear mounting columns 3 are longer than the two front mounting columns 3. Sliding sleeves 23 are provided around the bottom of the multi-person seat cushion 2. The sliding sleeves 23 are slidably connected to the mounting columns 3. The sliding sleeves 23 slide on the mounting columns 3 around the bottom. Connecting blocks 41 are provided on the front and rear sides of the bottom center position of the multi-person seat cushion 2. The top of the middle column 14 is fixedly connected to the connecting blocks 41, so that the middle columns 14 on the front and rear sides are fixedly installed at the bottom center position of the multi-person seat cushion 2, providing support for the center position of the multi-person seat cushion 2. Two intersecting connecting rods 11 are installed between every two adjacent support columns 1 and between the intermediate column 14 and the support column 1. There are six sets of connecting rods 11, located at the front, back, left, and right, with two sets at the front and back and one set at the left and right. A hinge rod 12 is installed at the middle of each connecting rod 11, rotatably connecting the hinge rod 12 to the middle of the two connecting rods 11. A first connecting bolt 13 is installed on the inner side of the bottom of the support column 1, rotatably connecting the first connecting bolt 13 to the bottom of the connecting rod 11. A second connecting bolt 24 is installed on the inner side of the sliding sleeve 23, rotatably connecting the second connecting bolt 24 to the top of the connecting rod 11. In use, when the folding chair needs to be unfolded, the surrounding support columns 1 are pulled outwards, causing the support columns 1 to move the bottom of the connecting rods 11 outwards synchronously via the first connecting bolt 13. When the connecting rod 11 is rotated and connected by the hinge rod 12 in the middle, the connecting rod 11 will gradually unfold with the hinge rod 12 as the fulcrum. At the same time, the top of the connecting rod 11 pushes the sliding sleeve 23 to slide down along the mounting column 3 through the second connecting bolt 24 until the support column 1 and the connecting rod 11 form a stable support frame. At this time, the multi-person seat cushion 2 is also fully unfolded, allowing two or more users to sit. When it needs to be folded and stored, push the support columns 1 around the perimeter inward. The support columns 1 drive the bottom of the connecting rod 11 to move inward through the first connecting bolt 13. The connecting rod 11 rotates and retracts around the hinge rod 12. At the same time, the top of the connecting rod 11 pulls the sliding sleeve 23 to slide up along the mounting column 3 through the second connecting bolt 24 until the support column 1 and the connecting rod 11 retract to a compact state, completing the folding.

[0020] The top rear of the multi-person seat cushion 2 is provided with a multi-person back cushion 21. The multi-person seat cushion 2 and the multi-person back cushion 21 are made of flexible fabric, such as canvas, Oxford cloth or breathable mesh. The top rear of the multi-person back cushion 21 is provided with mounting sleeves 22 on both sides. The mounting sleeves 22 are fixedly installed on the top of the two rear mounting posts 3, thereby fixing the position of the top of the multi-person back cushion 21.

[0021] A rotating component 31 is rotatably mounted on the rear mounting column 3. A connecting port 33 is provided in front of the armrest 32. The connecting port 33 is detached from the top of the front mounting column 3. A rotating port 4 is provided behind the armrest 32. A rotating frame 34 is provided in front of the rotating component 31. The rotating port 4 and the rotating frame 34 are rotatably connected. When the folding chair is unfolded for use, the connecting port 33 in front of the armrest 32 is aligned with the top of the front mounting column 3 and inserted and fixed. When the folding chair needs to be folded, first lift the front of the armrest 32 upward to disengage the connecting port 33 from the top of the front mounting column 3. Rotate the armrest 32 outward through the rotating component 31. Then, with the rotating frame 34 as the axis, rotate the armrest 32 backward to a state parallel to the rear mounting column 3 to avoid the armrest 32 obstructing the folding process.

[0022] The working principle of this utility model is as follows: When the folding chair needs to be unfolded, the surrounding support columns 1 are pulled outward. The support columns 1 drive the bottom of the connecting rod 11 to move outward synchronously through the first connecting bolt 13. Since the middle part of the connecting rod 11 is rotatably connected through the hinge rod 12, the connecting rod 11 will gradually unfold with the hinge rod 12 as the fulcrum. At the same time, the top of the connecting rod 11 pushes the sliding sleeve 23 to slide down along the mounting column 3 through the second connecting bolt 24 until the support column 1 and the connecting rod 11 form a stable support frame. At this time, the multi-person seat cushion 2 is also fully unfolded, allowing two or more users to sit.

[0023] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
