{LIFE JACKET FOR MARITIME DISTRESS}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a liferaft used in rescue operations in the event of a marine distress accident such as a ship or an airplane, and more particularly, It is about a lifejacket that can float in the air while it separates, so that the location of the victim can be quickly and easily notified.

A lifejacket is designed to prevent the occurrence of safety accidents such as drowning when enjoying leisure activities such as water sports such as river or lake, watering or fishing, windsurfing, rafting, etc., Is one of the water safety products to be worn and equipped.

These lifejackets have the basic function of lifting the head part to the surface of the water by buoyancy when the wearer falls into the water, as well as an additional function of preventing the body temperature from dropping and buffering the shock from the outside.

In general, the major cause of death of a victim in the event of a marine accident such as a ship or an aircraft is largely divided into heart shock due to drowning and temperature drop. In particular, if the structure of the victim is delayed, the death rate due to burnout or hypothermia is rapidly increasing, so rapid structure is needed.

However, when a marine accident occurs in a place such as the sea, and the victim drifts or disappears by waves, it must be searched over a wide area, so it is difficult to find quickly, and the nighttime In the dark or bad weather, the search and rescue activities as well as the location and tracking of the victims is very difficult to delay the structure.

Accordingly, a lifeboat with a balloon has been proposed to help the wearer to float on the water in the event of a distress accident and to remotely locate the balloon at a distance.

For example, Korean Patent Laid-Open Publication No. 10-2018-0069150 discloses a 'life vest equipped with a helium balloon' in which a wearer operates a valve of a helium gas cylinder to supply helium gas to a helium balloon connected by a connecting hose Which can float safely on the water, and the helium balloon, which floats high in the air, can tell the distant location to a far distance.

In order to float the helium balloon in the air, the flood bulb of the helium causes the victim to open the valve with one hand. If you have difficulties and inconveniences that you have to pull and pull with the other hand after pulling the hose in the opposite direction to pull it off, and if the victim falls into the water and gets lost or injured, helium balloons can float in the air There is no problem.

Herein, the background art or the prior art described above is only intended to help understand the technical significance of the present invention as information acquired by the present inventor or derived from the present invention, It does not mean that it is widely known in the field.

1 to 7, the main configuration of a distress life jacket 1 according to the first embodiment of the present invention is mainly composed of a balloon 11, a check valve 12, an inflator 13, 14, a hose 15, a connection cord 16, a releasing device 20, and a light emitting device 30.

The balloon 11 expands when inflated with a gas that is lighter than air and floats in the air. The balloon 11 is provided with durability such that it is not easily torn upon contact with elastic or sharp objects.

The envelope of the balloon 11 may be made of a light-accumulating or light-emitting material or may be coated with a phosphorescent material or a fluorescent material on its surface to facilitate identification.

Here, the balloon 11 may be folded in a flat shape before gas injection and stored or embedded in the pocket 10 formed on the back plate of the life span 1.

Also, it is preferable that the size of the balloon 11 is formed so as to have a buoyancy enough to support the weight of the victim (about 70 kg) when the gas is filled or float on the water.

The check valve 12 prevents the gas in the balloon 11 from leaking out, and is mounted on the spout of the balloon 11.

That is, the check valve 12 is provided so as to block the gas injected from the inflator 13 into the balloon 11, so as not to flow backward.

The inflator 13 is formed in the shape of a cylindrical pressure-resistant container bomb and inflates the inflated balloon 11 with a gas. The inflator 13 is attached to one side of the front face of the liferaft 1.

Here, the size of the inflator 13 is such that the gas can be filled in a compressed state enough to inflate the balloon 11, and the buoyancy of the lifejacket 1 is lowered due to the weight of the inflator 13 at the time of distress It is desirable to minimize the size and to have a volume that is easy to carry and store.

On the other hand, various kinds of gases may be used as the gas to be filled in the inflator 13 as long as they are lighter than air. For example, hydrogen, helium, nitrogen or the like can be employed.

The opening and closing valve 14 is formed by opening and closing the inflator 13 according to an artificial operation to quickly and easily open the spout (flow path) of the inflator 13 located at one side of the front face of the lifejacket 1.

Here, as the opening / closing valve 14, a structure in which the valve is kept in close contact with the seat by the compression force of the spring can be employed, and the valve is structured such that it is connected to the pulling ring (handle) When the valve is pulled down, the gas can be supplied to the balloon through the hose 15 by opening the spout, that is, the flow path, of the inflator 13 while the valve is lowered.

In addition, a variety of structures such as a button-type or lever-type structure capable of artificially inflating the inflator 13 by opening the flow path of the inflator 13 may be adopted as the opening / closing valve 14.

The hose 15 is connected to the check valve 12 through the opening and closing valve 14 and has one end connected to the check valve 12 located on the back plate of the life span 1, Closing valve 14 of the inflator 13 located on the front face of the life-saving machine 1. [0050] As shown in Fig.

The connecting cord 16 is provided between the balloon 11 and the lifejacket 1 and has a length enough to allow the balloon 11 to float in the air at a certain height so that it can be easily seen even from a long distance.

One of the connecting ropes 16 is fixed to the upper end of the backing plate of the liferaft 1, that is, the pocket 10, so that when the balloon 11 is floated in the air, the back of the victim can be pulled, .

The release device 20 expands at a pressure higher than the pressure at which the balloon 11 expands and separates the check valve 12 and the hose 15 so that there is a gap between the check valve 12 and the hose 15, So that they can be separated naturally and quickly by the pressure of the gas at the time of distress.

Here, the release device 20 is composed of a retaining tube 21 formed integrally with the check valve 12 and a material having elasticity such as silicone which expands at a pressure higher than the pressure at which the balloon 11 expands And an expansion pipe (23).

The expansion tube 23 is connected to the end of the hose 15 so as to communicate with the end portion of the hose 15. The expansion tube 23 is formed with a collar 22 that is inclined or bent at a predetermined angle, And a hook 24 having a shape corresponding to the collar 22 of the latching tube is formed at the other end thereof.

That is, when the gas is injected into the balloon 11, the engaging tube 21 is firmly and stably inserted into the expansion tube 23 due to contact interference between the collar 22 and the hook 24, The balloon 11 is completely inflated so that the check valve 12 is closed and the tightening force between the collar 22 and the hook 24 is released by the expansion of the inflation tube 23, As shown in Fig.

As shown in FIG. 7, the light emitting device 30 receives power from the battery 31 and emits or flashes light so that the position of the destructor can be quickly identified and structured. The balloon 11 is provided with a battery 31 therein.

A shielding film 32 for blocking the flow of current is provided between the battery 31 and the light emitting device 30. One of the shielding film 32 is provided with a battery 31 when the balloon 11 is fully expanded, And is fixed to the balloon 11 so as to escape between the light emitting devices 30.

Here, the light emitting device 30 may be formed of a LED light emitting device, and may have a structure that is sealed by a cover made of a hemispherical transparent resin material so as to facilitate diffusion of emitted light while preventing water from penetrating.

On the other hand, the lifejacket (1) basically has a buoyancy and a length and a volume which can support the weight of the wearer (the victim) in the water and can float safely on the water. And a normal fastening band, a buckle, a slide fastener, or the like may be provided so as to stably maintain the tight contact state with the upper body.

In addition, the life span 1 may be provided in a structure in which air is injected into a tube embedded between an inner skin and an outer skin, or a buoyancy material such as a foamed resin is embedded between an inner skin and an outer skin.

The liferaft 1 according to the first embodiment of the present invention constructed as described above is constructed so that when the wearer falls into the sea due to a marine accident or the like, if the inflator 13 is artificially operated, A gas lighter than air is injected into the balloon 11, so that the balloon 11 expands and buoyancy acts.

In this state, as shown in FIG. 4, when the gas pressure inside the balloon 11 becomes higher than a predetermined value, the check valve 12 is closed by itself and the gas in the balloon 11 is not discharged to the outside.

At this time, the expansion pipe 23 of the releasing device expands due to the gas pressure continuously discharged from the inflator 13. As a result, the expansion pipe 23 is fixed to the check valve 12 as shown in Fig. 5, The balloon 11 is automatically separated from the hose 15 connected to the inflator 13 so that the balloon 11 is automatically separated from the balloon 11 by the balloon 11, So that the position of the victim can be quickly and easily notified.

Therefore, unlike the prior art, it is not necessary for the victim to pull the balloon 11 and the inflator 13 or the hose 15 connecting them by pulling them in opposite directions to each other, However, it is possible to increase safety by obtaining additional buoyancy.

In addition, when the balloon 11 is fully inflated, the shielding film 32 for blocking the current flow is removed, and the power of the battery 31 is supplied to the light emitting device 30 to generate a flashing signal or light, 11) is brightly visible so that the position of the victim can be more easily and accurately communicated.

8 and 9, the main constitution of the distressing life swing motion 2 according to the second embodiment of the present invention is mainly composed of a balloon 11, a check valve 12, an inflator 13, 14, a hose 15, a connection cord 16, a bag 17, a releasing device 20 and a light emitting device 30. [

Particularly, the pouch 17 is provided so as to be able to receive and protect the balloon 11 and to be attached to and detached from the life-

That is, the pouch 17 can firmly hold the state attached to the life-saving motion 2 by a separate attaching / detaching member.

The attachment / detachment member may be formed of any one of a hook-and-loop fastener, a snap button, a button, and a slide fastener so that male and female are coupled to the pouch 17 and the life-

It is needless to say that the bag 17 can be easily attached to the shoulder portion of the lifejacket 2 using a buckle, a belt, or the like as the attaching / detaching member.

On the other hand, one side of the bag 17 is opened so that the balloon 11 contained therein can naturally escape outward when inflated by the gas injection.

The connecting cord 16 is provided inside the bag 17 to connect the balloon 11 and the bag 17 to each other.

As described above, according to the second embodiment of the present invention, the lifesaving lifter 2 does not require a pocket for receiving the balloon 11, so that it can be easily attached and used universally regardless of various lifesaving motions.
