The structure and characteristics of the umbrella：
The structure of an umbrella consists of three parts: the handle, the bone and the surface.The handle of the umbrella is the backbone of the umbrella, supporting the whole umbrella, mainly made of wood, iron, steel, aluminum alloy, fiber and other materials.The umbrella surface is the most important part of the umbrella, which is responsible for the protection of wind and rain as well as the sunshade. The production materials include silver adhesive cloth, pearl cloth, polyester plain color cloth, PG touching cloth and durable nylon cloth.
The umbrella invented by master lu ban's wife:
Umbrella, is an indispensable tool in People's Daily life, sunny day, it is for people to cover the sun, uv protection;On rainy and snowy days, it keeps the rain and snow off for people.But have you ever wondered who invented the umbrella we know so well?
As early as the end of the spring and autumn period more than two thousand years ago, there appeared in China a civil construction craftsman lu ban, who was respected as the "craftsman ancestor" by later generations.Later, it is said that lu ban, with his experience in building houses, invented a way to provide pedestrians with shelter, shelter from the sun and rain, and decorate the scenery.
Lu ban was a skilled craftsman, and his wife yun shi was also a person of extraordinary vulgarity.She saw her husband working outside for years, he suffered from the sun and rain, and secretly wondered: can you invent a "movable pavilion", let her husband take out, once the sun or rain, can let her husband hide in the past to shade from the rain?
After a long time of thinking, yunshi finally had an idea: she split the bamboo into thin strips, in the middle of a bamboo stick as a handle, those thin strips together, and then on the thin strips covered with animal skin, so that it closed like a stick, as open as a cover.An umbrella, a miniature portable "pavilion," was born.
From then on, when lu ban went out, he always took the umbrella with him to express his husband and wife's feelings.
Later, people in the cloud umbrella on the basis of continuous improvement, animal skin into silk;To the song dynasty with oil paper instead of silk, made paper umbrella.
At first, not many people with umbrellas, the people think that the rain, is to let people accept the rain baptism, umbrella is to god's disrespect.But as the umbrella does bring great convenience to people's life, people still gradually accept it.
Foreign "umbrella" has another development trajectory.The English name for the umbrella comes from the Latin for "vimbra", which means shade.Because in the west, the main body of the earliest umbrellas was a shade board with a taut piece of linen over it.
In ancient Greece, the umbrella shade was an indispensable foil for festival costumes.Slave owners let their servants hold the sun visor high behind them to show their power and nobility.Because the bearer of the umbrella must stand behind the owner, the handle of this kind of umbrella is not placed in the center of the umbrella, but on the side of the umbrella. By the middle ages, the umbrella had become a symbol of religious power (it is still a ceremonial staff of the Pope).The higher the status, the more luxurious the umbrella.The Pope's umbrella was exquisitely decorated with bright red and gold feathers, and its handle was carved with exquisite statues of angels.
Around the year 1747, an Englishman who was traveling to China took a fancy to the Chinese umbrella and returned home with an oil-paper umbrella made by the Chinese.Since then, the Chinese umbrella to the world, rain umbrella began to spread in Europe.
The early umbrella surface was made of heavy oil market, the handle and the spokes of the supporting umbrella were made of animal bones, bamboo and other things, which were relatively heavy to use, but it was effective in preventing rain, so it was loved by the public.
Around 1820, iron umbrella bones were made in England and Germany.The broken u-shaped umbrella bone in use today was invented in 1852 by William fox of England.
