Zippers are also called zippers. It is one of the top ten inventions that facilitate people's lives in modern times. The appearance of zipper was a century ago. At that time, in some places in Central Europe, people tried to replace buttons and bows with belts, hooks and rings, so they began to experiment with zippers.
Zippers were first used in military uniforms. During World War I, the US Army first ordered a large number of zippers to make clothes for soldiers. However, the promotion of zipper in the folk was relatively late, and it was not until 1930 that it was accepted by women to replace the buttons of clothing.
Zipper is the name obtained in 1926. It is reported that the novelist Francot said at a business luncheon to promote a zipper sample, "Pull it and it will open! Pull it again and it will close! " The characteristics of zipper are explained very concisely. The word zipper comes from this.
The embryonic form of the invention of zipper originally came from the boots people wore. /kloc-In the middle of the 0/9th century, boots were very popular, especially suitable for walking on muddy roads or roads with horse manure. But there are more than 20 hooks on the boots, and it takes a long time to put them on and take them off. This shortcoming is a headache for inventors, and it also costs sponsors a lot of money and patience.
In order to avoid the trouble of wearing boots, people even put up with wearing boots all day. Finally, in 185 1 year, elias howe, an American, applied for a patent for a similar zipper design, but it was not commercialized and even forgotten for half a century.
1893 (said 1883), an American engineer named Judson (Kuwaiti) developed a "sliding" device and obtained a patent, which was the original prototype of the zipper.
