Example

In conjunction with Figures 1-3, a portable folding chair comprises a front leg 1, a rear leg 2 and a seat 3. The front leg 1, rear leg 2 and seat 3 are in a flat plate shape when folded. The front leg 1 is in a frame shape. The rear leg 2 is located inside the front leg 1. The top of the rear leg 2 is hinged to the front leg 1. The seat 3 is hinged inside the rear leg 2. The bottom of the seat 3 is hinged to the center of the rear leg 2. At least one pair of bayonet holes 6 are provided on both sides of the seat 3, which may be two or three or more. The bayonet holes 6 are aligned and arranged. When the chair is opened, the inclination can be adjusted by inserting the bayonet holes 8 into the bayonet holes 6 at different positions. The front leg 1 is provided with bayonet holes 8 on both sides of the interior thereof to match the bayonet holes 6. The front leg 1, rear leg 2 and seat 3 are unfolded in an A-shape.

The front leg 1, the back leg 2 and the seat 3 are carefully carved from the same plate, presenting a unique nesting relationship. From the appearance, they seem to be integrated, presenting a simple but not simplistic beauty.

On this board, the front leg 1 is the outermost part, while the rear leg 2 and the seat 3 are shaped inwards in turn, forming a nested effect. This design not only enhances the overall sense between the components, but also makes the entire folding chair more visually coordinated.

The lower end of the seat surface 3 is connected to the rear leg 2 through a precise seat surface hinge 4, providing a stable support for the user. The top of the rear leg 2 is connected to the top of the front leg 1 through a rear leg hinge 5, ensuring the flexibility of the folding chair when folding and unfolding.

It is worth mentioning that the bottom of the front foot 1 and the rear foot 2 are both provided with a unique notch 10 design. This design cleverly solves the problem of the folding chair being unstable due to uneven ground. The structure of the notch 10 can effectively adjust the part in contact with the ground, ensuring that the folding chair can be placed stably on various ground surfaces.

In addition to the exquisite structural design, this folding chair also takes safety into consideration. All corners of the components are rounded to avoid accidental scratches during use. This kind of detail treatment not only increases the beauty of the folding chair, but also reflects the humanistic care for the user.

When the folding chair is folded, it is flat, which greatly saves storage space and is convenient for you to carry at any time. This design concept perfectly combines practicality and beauty, making this folding chair an ideal choice for home, office or outdoor use.

From the perspective of production cost, all parts are processed on the same plane, which not only simplifies the production process, but also greatly reduces the generation of waste. This processing method not only improves production efficiency, but also helps maximize the use of resources and saves costs for the company.

In summary, this folding chair has become a highlight product in the market with its unique design, practical functions and reasonable production methods. Whether from the perspective of aesthetics, safety or economy, it is a recommended choice.

The connection between the rear foot 2 and the front foot 1 realizes smooth and stable rotation through a precise rear foot hinge 5. This design makes the folding chair smoother when folding and unfolding, while also ensuring the stability of its structure.

The bottom of the seat surface 3 is hinged to the center of the rear foot 2 through the seat surface hinge 4, which further enhances the stability and load-bearing capacity of the folding chair. This hinge method ensures that the seat surface can remain flat in various use states, giving the user a comfortable sitting posture.

The seat surface 3 is covered with a layer of soft cushion, which greatly improves the comfort of the folding chair. This design takes into account the needs of long-term use, allowing you to enjoy a comfortable sitting posture in various occasions.

The four corners of the front foot 1 are all rounded, a design detail that fully reflects the care for the user. The rounded corner structure avoids the risk of scratching the human body due to accidental collision, making your use process more secure.

The notch 10 at the bottom center of the rear foot 2 and the front foot 1 is ingeniously designed. This design allows the folding chair to better adapt to uneven ground when placed, ensuring its stability. At the same time, the legs formed on both sides contact the ground, reducing the contact area and effectively avoiding the problem of overall instability caused by small objects such as stones.

The hanging hole 7 in the center of the rear foot 2 provides convenience for storing the folding chair. You can hang the folding chair on the hook to save storage space and make your home tidier.

The hollow holes 9 on both sides of the front foot 1 are both beautiful and practical. These hollow holes make it easy for you to pick up the folding chair with your fingers or index fingers, while its curved design and rounded edges ensure safety in use. The hollow design also reduces the overall weight of the folding chair, making it easier to carry and move. This design takes into account the needs of different usage scenarios, making the folding chair more versatile and convenient.

In addition, the overall structure takes into account ergonomic principles to provide optimal comfort and support. Whether it is used at home, in the office or outdoors, this folding chair can meet your needs and become a capable partner in your life.

Working principle:

When unfolding, it is only necessary to unfold the rear legs 2 backwards to form a certain angle with the front legs 1, and at the same time flip the seat surface 3 forward and downward to open it. A bayonet 6 is respectively provided on the left and right sides of the seat surface 3, and correspondingly, corresponding slots 8 are respectively provided on the front legs 1. The bayonet 6 of the seat surface 3 is inserted into the slot 8 of the front legs 1, so that the seat surface 3 can be firmly fixed on the front legs 1, and the three form a stable triangular structure; a seat with a stable structure can be formed.

The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
