Introduction to the Origin and Structure of Vertex

Speaking of the word "first", the idiom "first" should come to mind at the first time. Today, this idiom means that a person has an important position or a high position. So how did this idiom evolve? What does number one look like? Everyone should be curious, so today we will introduce the origin of the number one, and everyone will understand why it is so valuable today.

Origin:

Before the Han and Wei Dynasties, the ancients sat on the floor and naturally had no chairs. And "bed", in the early days, was a seat, not a quilt. Shuowen explained: "Bed, a person sitting in a safe place." Obviously, the main function of the bed is sitting. During the reign of Emperor Ling of the Han Dynasty, a kind of "Hu bed" was introduced from the north, which looked like a low stool, and a rope bed was introduced at the same time with the Hu bed. The rope is bifurcated and can be folded, which is a modern Mazar. This rope bed was later called Hu bed.

In the Sui Dynasty, because the word "Hu" was taboo, and this chair was characterized by split wooden feet, it could only be hidden after opening, so it was renamed as "sedan chair". Cheng Dachang, an Amin, said in "Exposed": "It is enough to make the bed at noon ... When the feet cross, they are round and ground, so they can be put on the table; With its fork, it is called a bed. " "noon crossing" refers to the middle crossing, and "noon crossing" refers to the position where the legs of Hu bed cross in the middle. In the Southern Song Dynasty, people renamed sex as a top priority. It is said that Qin Gui, the prime minister of the Southern Song Dynasty, always leaned back when sitting on the bed, so that the towel fell off. In order to kiss Qin Gui's ass, Silent and Wu Yuan specially put a backrest on the back of the bed, which is called "plush chair".

In the hierarchical feudal society, the top spot is not for anyone, but a noble symbol of status and status. It is precisely because the top spot has such a special role that "sitting on the top spot" has become synonymous with leaders.

? ? Technology:

The top chair in Ming Dynasty is famous for its beautiful and smooth shape. Its chair ring curve is soft and comfortable, commonly known as "crescent armrest". It is made of three to five tenons, and the two ends of the handrail are decorated with moire heads, which is noble and dignified. Relief lighting is applied above the back of the chair, reflecting the pure spirit, and the "goose head" on both sides is slender, elegant and atmospheric. The chair surface is mostly made of hemp rope or leather, and the pedal is placed at the bottom of the forefoot, which is suitable for decoration and practicality. Carved teeth are generally provided between handrails, backrests, legs and feet, and the joints are also wrapped and inlaid with copper decorative pieces, which not only plays a stable role, but also plays a role in embellishment and beautification. Because the top chair is foldable and easy to carry, it was often used in field trips, hunting and marching operations in ancient times. Later, it gradually evolved into hall furniture, which is the seat of the scene. It is said in ancient books that those heroes sit in the first place according to their generations, which stems from this.

When the top chair entered the hall, its cross-folded legs had lost their original field use function, so someone changed it into four straight legs of a conventional chair and became a "round-backed chair". Huang Huali is the rarest Ming-style chair handed down from ancient times, but there are also many miscellaneous wood chairs.

Structure:

All connecting parts are made of scientific and reasonable tenon-mortise structure, and the seat ring is specially made of die nails and tenons to achieve the purpose of firmness. Metal columns are installed at the bent parts of the handrails and hind legs, which reduces the adverse effects of load bearing on the bent parts of the hind legs. At the same time, the slender and sturdy metal columns skillfully separate the space below the chair ring, giving people a sense of beauty. Put your foot teeth in the corner. This not only plays the role of filling space, but also plays a certain decorative effect. The tenon is wrapped with metal blades to reinforce and prevent wear. It is precisely because the craftsman adopted a relatively reasonable structural design that the chair still stands after vicissitudes.

Above, we introduced some knowledge about the first chair. First, we introduced the origin of the first chair. The idiom "number one" has existed for so long, so it has a long history. Then we introduced the design technology of the first chair. Finally, we introduced the structural design of the first chair. The reason why the first chair has been loved by people for so many years is inseparable from the exquisite technological structure.
