[Inflatable life jacket] The scope of application principle of inflatable life jacket work inflatable life jacket
Origin -Who invented the "life -saving vest"
In 1944, the former President Bush, as a naval pilot, was shot down over the Pacific Ocean, but he succeeded in parachute and escaped. He was wearing an inflatable "life -saving vest".And the invention of life vestAndrew Totti has always been considered a hero.
However, today, who has invented the "life vest" for decades later, it has caused controversy.After investigation, there was no record of Totti invented in the patent record.A person named Peter Marcus registered the patent of life jacket in 1928, and his design was very similar to the World War II military life jacket.
Is there a patent record of Macus in the archives?
The life -saving vest is an inflatable vest life jacket worn by pilots when flying over the sea.As the inventor, Totti has been praised by people. Of course, the most grateful to him is the old Bush.
Until March this year, after the 89 -year -old Totti died, people still praised his invention as always in the prosecution, grateful for everything he did to save the life of the future president.
But then, the government's documents showed that Peter Marcus had obtained the patent right in 1928.That is, a few years ago when Tott began to design a life jacket, Marcus had begun to study and improve life jackets with the military.Marcus died in 1973.Macus's son and Alvin from Los Angeles provided several certification documents to the Associated Press.The document shows that on December 11, 1928, Marcus's "inflatable life utensils" obtained a patent with patent number 1694714.At that time, Totti was only about 11 years old.
Subsequently, the Associated Press reporter found in the military -related records of the National Archives that since 1930, the Naval military has begun to create a life jacket designed by Marcus.
Toti frankly accepted the praise and wrote the "Congress Records"
Tetty's will and mechanic Russell Hindley revealed that Totti said that when he was a teenager, he sold his life -designed life jacket to the US Army at the time.
"(He) has never said that he is the inventor. He has always called himself a partnership," Xinkeli told the Associated Press reporter that he worked with Totti for decades. ") Have contributed. But Peter Marcus is the inventor. "
Totti has hundreds of invention patent rights, including automatic chicken wiper and respiratory straws for surgery.Over the years, when others praised him invented a life -saving vest, Totti obviously had not denied it.
In 1995, the "ranked" magazine in the United States also wrote Totti.Last year, Republican Dennis Cato from California also praised him to save the life of the future president.Kadaza even wrote Totti's deeds into the Congress record.
The life jacket has continued to improve the reporter's investigation and the inventor failed
Prior to the release of Toti, Alvin said that he had never heard of Totti, let alone Totti selling the life jacket to the military."Selling $ 1500 is a joke at all," he said.According to him, his father, Macus, has obtained thousands of dollars of patent use fees from two authorized rubber companies.However, he also acknowledged that Totti may have improved some improvement in life jacket design.
In order to clarify the matter, the New York Times hired a professional patent lawyer Steven Liberman to inquire about the patent records, but no record of Totti inventing a life jacket was found.The life jacket designed by Marcus is the most similar to the life vest used by the military in the patent record.
In fact, before World War II, people have been constantly improving life jackets.A long time ago in Marcus's registration patent, some people have obtained similar patent rights.Therefore, the life jacket used by the military during World War II may also be from the hands of others.
The working principle of inflatable life jacket
The inflatable life jacket has two functions: manual exhaustion and automatic inflatable.
1. Manual inflatable: Pull the pull rope on the inflatable device before or after falling or after falling or after falling or after the water, so that the tie rod is not less than 90 degrees, the thorns are pierced to pierce the gas cylinder film, the high -pressure CO2 gas is poured into the airbag, and the buoyant is generated after the gas swells.
2. Automatic inflation: After the water is dropped into the water, the life jacket is immersed in the water to soften the water sensitive element in the automatic device, loses blocking the needle, and the spring stretch pushes the piercing needle to pierce the gas cylinder sealing film CO2 gas to fill the airbag and generate buoyancy.
3. Blowing the mouth is a one -way valve type, and the one -way valve is automatically closed after blowing.
Scope of application of inflatable life jacket
Inflatable life jackets are widely applicable to the application of passenger ships, yachts, military, water police, water police, water anti -smuggling boats, water construction operations, maritime drilling platforms, flood relief, salvage flood control, pilot, hydrology, water conservancy and other fields.
