Abstract
The utility model relates to a lifesaving appliance and is especially a swimming lifesaving appliance. The appliance is provided with a gas bag and the gas bag isn't filled with gas when the gas bag is fixed on the body of a user. The user controls a gas source appliance to make the gas bag be filled with gas if necessary. Because the gas bag that isn't filled with gas is fixed on the body to be used, the obstruction for the movement of the user is small. The resistance in water is also small. The appliance can be the auxiliary lifesaving means for various operation people on water when the appliance is integrated with a swimming suit or various work clothes.
Description
The utility model relates to a kind of lifesaving appliance, particularly the swimming lifesaving device.
Lifesaving appliance in the past all is to use air bag or low density solid material.This lifesaving appliance carries and uses clumsiness and inconvenience.Be anti-just in case, when swimming,, on one's body the swimmer also must the lifesaving appliance that volume is very big be enclosed within, very inconvenient even do not use.
The present utility model purpose provides a kind of very little to the movable influence of user, and resistance is also very little in water, is suitable for the lifesaving appliance that the swimmer uses.
The purpose of this utility model is achieved by the following technical solution: be communicated with an air bag and a compressed air source unit with a ventilation flue, user's may command compressed air source unit is to airbag aeration in case of necessity.Produce buoyancy behind the airbag aeration, can reach the lifesaving purpose.
Describe the utility model in detail below in conjunction with accompanying drawing.
As figure, shown in: 1 is air bag among the figure, the 2nd, and the ventilation flue, the 3rd, compressed air source unit, the 4th, shell, this shell is made with elastomeric material, as plastics, rubber etc., the 5th, sodium bicarbonate (NaHCO
3) powder, the 6th, aqueous acetic acid, the 7th, the paraffin interlayer, the 8th, sealing film, the 9th, be used for the belt of colligation air bag.
During use, with belt air bag is fixed on user's chest, when in case of emergency, as long as firmly push compressed air source unit with hand, casing deformation causes the paraffin interlayer to break, and acetic acid and reaction of sodium bicarbonate generate carbon dioxide (CO
2) gas, carbon dioxide breaks through sealing film, enters air bag by the ventilation flue, just can be to airbag aeration.
The utility model also can adopt other structures, as shown in Figure 2: extend some minutes air bags 10 at the air bag upside.This air bag can colligation at user's waist, preferably with mode colligation shown in Figure 3.
Air bag also can be made closed loop, and this moment is as long as just can use Air sac cover on one's body, easily.Fig. 4 represents the shape after the air bag of first kind of form (being form shown in Figure 1) is made closed loop, and Fig. 5 represents the shape after the air bag of second kind of form (being the represented form of Fig. 2) is made closed loop.
Air bag also can with the swimsuit use that is connected as a single entity, as shown in Figure 6,11 is swimsuit among the figure.
Air bag can also be connected as a single entity with various working clothess, such as lining or overcoat as sailor, seaman and various operation at sea staff's working clothes, for above-mentioned personnel at all levels as auxiliary survival means.
The utility model uses with it owing to the air bag that will not inflate is fixed on the user, so hinder hardly user's activity, resistance in water is very little, adapt to swimmer's requirement fully, when in case of emergency, as long as catch firmly extruding of compressed air source unit, make casing deformation, just can control it to airbag aeration, gas replenishment process is convenient and reliable.
