Description

Buoy for both swim-learning and automatic lifesaving

The present invention relates to the swimming of swimming activity, the lifesaving of activity in lifesaving and other water.

Existing swimming or the buoyant apparatus of helping is the life jacket of weighting material as air ring or with the light material, and buoyancy is scheduled to, can not vary with each individual, and resistance is generally bigger due to the shape, is unfavorable for that the beginner learns swimming, meeting swimmer then inconvenience carries, and causes the swimming season and easily has an accident.

The object of the present invention is to provide to help swimming buoyancy under a kind of normal circumstances or do not have buoyancy, but in case of emergency all can inflate the utensil of lifesaving effect automatically

The present invention includes gas generator, ventilation flue, clothing formula or air ring formula air bag etc.Its core is a gas generator, and it has two kinds of single chamber and two chambers, and single chamber only is lifesaving gas generating chamber, and two chambers add in addition and help swimming gas generating chamber, the shared gas piping in two Room.Help swimming gas generating chamber inlet opening switch to can be various forms of hand switches, turn on the switch water inlet when the indoor an amount of chemical reagent that can produce gas with water or seawater reaction that is equipped with, following water and can produce gas, gas enters air bag through gas piping.Regulate the chemical reagent amount in advance, can produce beginner oneself and feel that suitable buoyancy helps swimming, help swimming gas also can be blown into or squeeze into mouth through the ventilation flue with inflator.Progressively planned minimizing reagent is buoyancy, can help the beginner to learn swimming in than short-term, the lifesaving generation of gas is indoor the more amount chemical reagent, and the inlet opening is the body spare of producer, inwall is a screw thread, and it can manually or utilize the switch of hydraulic pressure self-opening to control by one.This switch is made of jacket casing, Nei Sai and elastic force apparatus, has time-delay open and close function, the jacket casing appearance is the screw thread that cooperates with the inlet opening, table is light knot degree light face preferably in the front end, the rear end is the muscle cage that several muscle are formed, and aft end face has an aperture and covers the removable cover of this aperture, interior plug is-solid cylinder that length is suitable that one little convex surface is arranged in the middle of its front end face, aft end face has a screw, can fix a suitable spring.Interior plug can be put into jacket casing more tightly, under suitable pressure effect through the short period, interior plug can overcome the elastic force of spring and enter the muscle cage of jacket casing rear end, and switch open water inlet this moment produces enough buoyancy to a large amount of inflations of air bag automatically with the promptly very fast gas that produces of reagent reacting.Water inlet is an amount of and after reaction in short-term, and this switch is under the effect of room pressure and spring, and Nei Sai can enter the jacket casing front end and automatically resets and close from the muscle cage, in case gas runs in the entry.The self-opening of swimming activity, adult usefulness should be that depth of water 2-3m is advisable with 0.2-0.3 air pressure, what child used is that depth of water 1-2m is advisable with 0.1-0.2 barometric pressure, activity can optionally be decided in other water.Delay function can be got rid of the interference of water wave fluctuating pressure.When the time length that reaches related pressure when being suitable, such as about 5 seconds, switch can the self-opening water inlet, and pressure surpasses more for a long time, then can very fast unlatching.By simple exercise, when emergency situation took place, the user was if calmness can manually be pressed out switch, if the user then utilizes the hydraulic pressure self-opening when flurried, and it is dark more to sink, self-opening is fast more, and airbag aeration is also fast more, therefore can avoid the contingency of water activity fully.

Clothing formula air bag, woman style can change the swimming costume of current trend into bilayer or only be bilayer more than the waist, and man style can be double-deck vest formula.These two kinds of air bags can join two chambers gas generator, also can join single chamber, and producer should embed at waist.The circle type air bag be can make in addition in addition and swimming trunks top or other shape are placed on.Have on the air bag conduit can with the gas piping of producer carry out air tight, watertight connection.

Each parts of gas generator are better with water resistance, non-metal or suitable metal making such as harder rubber, plastics, conduit, air bag suitable rubber or plastics manufacturing.

Now in conjunction with the accompanying drawings invention is described further.

Accompanying drawing is the switch of lifesaving gas generating chamber inlet opening.
