Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Referring to the accompanying drawings, a folding chair includes a support body 100 formed by splicing together a front cross assembly 1, a rear cross assembly 2, a left cross assembly 3, and a right cross assembly 4. A backrest vertical tube assembly 5 for backrest support is connected to the rear cross assembly 2, and a support vertical tube assembly 6 is connected to the front cross assembly 1. The length of the front cross assembly 1 is greater than the length of the rear cross assembly 2. Figure 5In the diagram, the width indicated by A is greater than the width indicated by B. In the embodiments provided in this application, both the backrest vertical tube assembly 5 and the support vertical tube assembly 6 consist of two vertical tubes; the four sets of intersecting assemblies (front, rear, left, and right) consist of two tubes hinged together in the middle. More specifically, the upper end spacing of the support vertical tube assemblies 6 is greater than the lower end spacing of the support vertical tube assemblies 6, i.e. Figure 5 In the diagram, the width indicated by C is greater than the width indicated by D. Furthermore, the upper spacing of the supporting vertical tube assembly 6 is also greater than the width spacing of the backrest vertical tube assembly 5. Figure 5 In the diagram, the width indicated by point C is greater than the width indicated by point E.

[0031] This application utilizes a support body 100 composed of the aforementioned four sets of cross components, backrest vertical tube assembly 5, and support vertical tube assembly 6. The length of the front cross component 1 is greater than the length of the rear cross component 2, and the upper spacing of the support vertical tube assemblies 6 is greater than the lower spacing of the support vertical tube assemblies 6. Furthermore, the upper spacing of the support vertical tube assemblies 6 is also greater than the width spacing of the backrest vertical tube assembly 5. This allows the folding chair to achieve its folding function while maintaining its compactness and stability, and also provides ample legroom for the user, thus improving user comfort.

[0032] The folding function is achieved through the following means: the lower end of the support vertical tube assembly 6 is hinged to the lower end of the front cross assembly 1. The bracket body 100 includes a support foot connector, which includes a rear support foot 7 and a front support foot 8. The rear support foot 7 is provided with an insertion hole 75 that connects to the backrest vertical tube assembly 5, a first hinge portion 71 that connects to the rear cross assembly 2, and a second hinge portion 72 that connects to the left cross assembly 3 or the right cross assembly 4. The front support foot 8 is provided with a third hinge portion 81 that connects to the left cross assembly 3 or the right cross assembly 4, and a fourth hinge portion 82 that connects to the front cross assembly.

[0033] It also includes a chair fabric 200, which is detachably fitted onto the support body 100. The backrest vertical tube assembly 5 is provided with a first sliding connector 51, which has a first connecting portion 511 that mates with the rear cross assembly 2, and a second connecting portion 512 that mates with the left cross assembly 3 or the right cross assembly 4. The upper end is also provided with a first support surface 513 for supporting the chair fabric 200. Since the first sliding connector 51 is located on the backrest vertical tube assembly 5 and can move along the vertical tube, it is provided with a first through hole 514.

[0034] The supporting vertical tube assembly 6 is provided with a second sliding connector 61. This second sliding connector 61 has a third connecting portion 611 that mates with the front cross assembly 1, and a fourth connecting portion 612 that mates with the left cross assembly 3 or the right cross assembly 4. Its upper end is also provided with a second supporting surface 613 for supporting the chair fabric. Since the second sliding connector 61 is provided on the supporting vertical tube assembly 6 and can move along the vertical tube, it is provided with a second through hole 614.

[0035] In addition, a limiting member 63 is provided on the supporting vertical tube assembly 6. The limiting member 63 restricts the maximum distance that the second sliding connector 61 can move downward, providing the user's legs with a better height space.

[0036] In addition, the chair fabric 200 also includes an armrest fabric 201. A fastener 62 is provided at the upper end of the support tube assembly 6, and the fastener 62 is provided with a fifth connecting part 621 that cooperates with and connects to the armrest fabric 201 of the chair fabric 200.

[0037] In the use of this application, the chair can be opened and folded by pulling or pressing the support body 100. During the folding process, the first sliding connector 51 and the second sliding connector 61 move along their respective mating vertical tubes, simultaneously driving the rotation of the four sets of cross components around their own hinge points and the rotation of the four sets of cross components and their respective mating support leg connectors, thereby achieving the folding function. In the open state of the folding chair, due to the structural design of the support body 100, the top view of the support body 100 is trapezoidal. The above-mentioned structural design, while ensuring the compactness and stability of the folding chair, also provides the user with a larger legroom, improving user comfort.

[0038] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
