The structure and invention of the umbrella
The structure of the umbrella is roughly composed of three parts: umbrella handle, umbrella rib, and umbrella surface. The umbrella handle is the main backbone of the umbrella and supports the entire umbrella. It is mainly made of wood, iron, steel, aluminum alloy, fiber and other materials. The umbrella bone supports the entire umbrella surface. It can be folded and opened for easy carrying; The surface is the most important part of the umbrella. It bears the responsibility of sheltering from wind, rain and sun. The materials are made of silver tape, pearl cloth, polyester plain cloth and (PG) touch cloth and durable nylon cloth.
The umbrella invented by Master Luban’s wife:
Umbrella is an indispensable appliance in people’s daily life. On sunny days, it protects people from sun and ultraviolet rays; on rainy and snowy days, it protects people from rain and snow. But have you ever wondered: Who invented the umbrella we are so familiar with?
As early as the end of the spring and autumn more than two thousand years ago, there appeared a civil construction craftsman Lu Ban who was regarded as the “ancestor of craftsmen” by the later world. He was ingenious and invented the world’s first one inspired by the shape of weed leaves. Lie in. It is said that Lu Ban later invented things based on his experience in building and repairing houses for pedestrians to rest on their feet, shade and keep out the rain, and decorate the scenery.
Lu Ban is a skilled craftsman, and her wife Yun is also a vulgar one. She saw her husband working abroad for many years, and he was suffering from the sun and rain, so she wondered whether she could invent a kind of “moving pavilion” for her husband to take out, and once the sun or rain came, he could hide him In the past to shelter from the rain?
After a long time of thinking, Yun finally had an idea: She split the bamboo into thin strips, using a bamboo stick as a handle in the middle, and gathered the thin strips, and then covered the thin strips with animal skins to make them gather like The stick, opened like a lid. A shrunken “Pavilion” that can be carried around, an umbrella, was born.
From then on, when Lu Ban went out, he always took this umbrella that condensed the feelings of their husband and wife.
Later, people continued to improve on the basis of the Yun’s umbrella, replacing animal skins with silk; in the Song Dynasty, oil paper was used instead of silk to make paper umbrellas.
In the beginning, there were not many people who used umbrellas. The common people believed that God’s rain is to let people accept the baptism of rain, and that umbrellas are disrespectful to God. But because the umbrella really brought great convenience to people’s lives, people gradually accepted it.
