Description

The structure and method of life jacket

The present invention relates to a structure and method of a life jacket that can be used by a user to assist the user in righting himself on the water.

The development of Taiwan's fishery and the prosperity of marine activities in recent years are extremely important for maritime safety. However, because Taiwan is located in a subtropical region, typhoons are frequent, resulting in endless shipwrecks. After most of the victims fell into the sea and disappeared, search and rescue was difficult because of the poor visibility due to the changing nature of the walrus, and because ordinary life jackets did not have a positioning function.

In addition, there are many people in Taiwan who enjoy river tracing activities. To ensure safe river tracing activities, they must wear life jackets to ensure their safety when falling into pools or deep water areas. Therefore, some manufacturers have also developed life jackets that can be turned back, such as the Republic of China Patent No. 560509 "Improvement of the Floating Structure of Life Jackets". The main function is to extend the airbag from the back of the neck to the front of the chest. The airbags below the neck gradually increase to the front of the chest. The air bag is the largest. It is carried on the front of the chest and the body is tied with a strap. At this time, the drowning person, because the air bag in the chest part is large, there is more air and the buoyancy is greater. In addition, the body and limbs sink, and the drowning person can turn over to his face. Face up, turn the drowning person face up again.

However, when the above-mentioned improvement of the floating structure of the life jacket is used, the following problems and deficiencies do exist and need to be improved:

Although the life jacket can ensure personal safety and prevent drowning, this patent cannot truly achieve the righting effect. When the person's face is face down, or the person is unconscious, the person may be tilted due to different body areas or angle problems. , and pressing the air bag will cause the air bag to be pressed under the person and unable to be correctly turned, so there is still a possibility of drowning.

Therefore, how to solve the above conventional problems and deficiencies is the direction that the inventor of the present invention and related manufacturers engaged in this industry are eager to research and improve.

The main subject of the present invention is to provide a method for sequentially filling the first chamber and the second chamber with gas and liquid through a gas filling device and a liquid filling device, so that it can assist the personnel in correct correction without A drowning situation can occur.

The main structure of the present invention to achieve the above object includes a plurality of first chambers arranged in parallel and a plurality of second chambers arranged in parallel, and the second chamber is located on one side of the first chamber. In addition, the first chamber It is connected to a gas filling device, the second chamber is connected to a liquid filling device, and at least one liquid sensing element is provided on one side of the first chamber. In addition, the gas filling device, the liquid filling device, and the liquid sensing element are Electrically connected to at least one power supply component.

When a person falls into the water and his face faces the water, the liquid sensing element will first sense the liquid. At this time, the power supply element immediately supplies power and the liquid sensing element controls the gas filling device to fill the first chamber with gas, and the liquid filling device fills the second chamber with gas. The chamber is filled with liquid. During the operation, the gas filling device is sequentially filled from the first chamber on one side to the first chamber on the other side, and the liquid filling device is filled from the first chamber on one side. The two chambers are sequentially filled into the second chamber on the other side, and the first second chamber filled by the liquid filling device is at the same position as the first chamber filled by the gas filling device. The opposite side allows the person to slowly turn over to the front, with the face facing the sky, so that the person will not be unable to turn over due to body pressure, which may cause a drowning crisis.

Through the above technology, the buoyancy structure of conventional life jackets can be improved. Although existing life jackets can ensure personal safety and prevent drowning, this patent cannot truly achieve the righting effect when the person's face is facing down, or the person has fallen. In a comatose state, the person may press the air bag due to different body areas or angle problems, causing the air bag to be pressed under the person and unable to be correctly turned, so there is still a possibility of drowning. Make breakthroughs to achieve the practical advancement of the above-mentioned advantages of the present invention.
