In BC 1 100, people in China already used umbrellas to identify themselves. The ribs are made of bamboo or sandalwood, and covered with an umbrella cover made of leaves or feathers. The word "umbrella" only appeared in English in the12nd century. According to Asian legend, during the Warring States Period, the wife of China craftsman Lu Ban invented the first umbrella, which was the first folding umbrella that could shelter from rain and pick flowers, and its basic structure has been used to this day.

1928, Hans Haupt, a German, invented the first telescopic umbrella for a long-handled umbrella that was inconvenient to carry with crutches. After shrinking, it can almost be put into your pocket, so it is also called a pocket umbrella.
In the1930s, Lao Yan, a mechanical scientist in China, thought of using silk as an umbrella cover, with a foldable steel frame, and the handle could be shortened and put in a handbag. After the sample was made, Lao Yan couldn't find a manufacturer to produce it, because at that time, the income of Chinese people was low and they couldn't afford a folding umbrella with a higher price than a straight handle oil-paper umbrella. Later, this technology spread to China and Shanghai, and a small number of products went on the market, but they were soon discontinued because of unsalable sales.
1969, Bradford e Phillips of Loveland, Ohio, USA obtained a patent for the folding working umbrella.
