The present invention relates to a life jacket equipped with a heating means so that a distress drifting in water due to a disaster such as a ship accident or an aerial accident does not die due to a sudden temperature drop. More specifically, the inlet check valve is provided with an opening / closing plate so that heat can be continuously generated for a long time, and a delay means is provided to delay the heat generation reaction after a predetermined time elapses after contact with water to increase the survival time. It relates to a life jacket having a heating means to cover the surface.

In general, life vests are used to prevent personnel accidents during leisure activities on the shores of rivers, lakes, and seas. However, if it takes several hours to several days to rescue a distress, such as when a disaster or a victim is unconscious, it cannot be said that the above functions are used alone.

That is, most of the causes of death of the distressed drowning are verbs or exhaustion, which come from hypothermia. In order to prevent death from verbs or exhaustion, it is important to know the location of the distress quickly and accurately.

Conventional inventions related to the tracking of displaced persons in order to detect the position of the distressed person include the Korean Utility Model Publication No. 20-0186202 (registered on July 7, 2000) 'Wireless Rescue Signal Transmitter', and Korean Patent Publication No. 10-0378580 (2003.03) .20 registration) 'survival and location system of the victims'.

However, it is important to find the position of the distress quickly and accurately as above, but more importantly, the survivor must survive until the rescue. It depends on the temperature of the water, but after two or three hours after being drowned in water, the stamina begins to drop sharply and the mind becomes confused. This phenomenon is mainly caused by a sharp drop in body temperature.

An object of the present invention is to provide a life jacket equipped with a heating means so that the distress does not die before being rescued by a sudden decrease in body temperature.

In addition, another object of the present invention is to provide a life jacket equipped with a location tracking terminal and a night light emitting means so as to quickly and accurately locate a distress person.

Life jacket of the present invention for achieving the above object,

A vest body having a front part, a back part, and a collar part surrounding the body chest, back, and neck;

An accommodation part provided in the vest body;

A heat generating pack housed in the accommodating part and provided with an inflow check valve and a discharge check valve, and a heating element built in the heat pack and dissipating heat by reaction with water introduced through the inflow check valve Heating means comprising a; made to include,

The inflow check valve provided in the heating pack of the heating means is characterized in that it comprises an opening and closing plate for closing the inlet by the pressure of the gas generated by the reaction of the heating element and water,

The inlet of the inlet check valve provided in the heat pack of the heat generating means is characterized in that it is further provided with a delay means for introducing water after a predetermined time after contact with water.

And the vest body is another feature that is equipped with a location tracking terminal and the night light emitting means.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view and a rear view showing a life jacket according to the present invention.

Referring to this, the life jacket of the present invention is a front body 11, the rear portion 12 and the collar (collar) 13 consisting of the main body 10, and the receiving portion 14 of the vest body 10 It includes a heat generating means 20, the position tracking terminal 30 and the night light emitting means 40 mounted on the vest main body 10.

First, the vest main body 10 will be briefly described.

As shown in FIG. 1, the support belt 15 is attached to the front part 11 in two rows or three rows in order to firmly wear the vest body 10 to the body of the distress. The connection of the support belt 15 is preferably by the coupling of the male / female buckle formed at its end in terms of simplicity and safety of the coupling.

The collar portion 13 is to protect the head portion by generating more buoyancy on the head of the wearer, made of a half-moon shape surrounding the wearer's neck and head and detachable from the front portion 11 and the rear portion 12 It is possible.

And although not shown in the figure, there is a buoyancy member in the interior of the vest body (10).

The buoyancy member is a foamed resin made of low-density sheet polystyrene, and a plurality of sheets are formed to overlap the element elements of the vest body 10. The low density thin polystyrene foamed resin is not only light, but also has excellent buoyancy and excellent durability.

In order to minimize the physical dissipation of the distress and to prevent the distress face from contacting the water in the unconscious state, that is, the buoyancy of each part of the vest body 10 was changed so that the comfortable posture was naturally made.

To this end, in order to generate more buoyancy and protect the head part, the collar part 13 used a low-density thin polystyrene material superimposed over 100 g to support the neck and the head by cutting in half moon shape.

The low-density thin polystyrene foamed resin was overlapped with 40 to 45 sheets on the front portion 11 and 35 to 40 sheets on the rear portion 12 to generate more buoyancy on the front portion 11 than the rear portion 12.

Figure 2 shows a heating means 20 according to the present invention, (a) is a perspective view, (b) is an exploded perspective view, (c) is a check valve (22a, 22b) and the opening and closing plate 25 provided therein ) And a retardation means (26). As shown in FIG. 1, the heat generating means 20 is housed in an accommodating part 14 provided in the front part 11 of the vest body 10.

The heating means 20 is to prevent the rapid temperature drop of the distress who is immersed in water, to prevent the verb and physical consumption.

For this purpose, the heating means 20 is mounted adjacent to the heart, that is, on both sides of the chest,

The exothermic temperature delivered directly to the body by the exothermic means 20 is preferably similar to or slightly higher than the body temperature, i.e., around 40 ° C, and the exothermic time is preferably long-lasting.

As shown in FIG. 2, the heat generating means 20 includes a heat pack 21 having a waterproof function, an inflow check valve 22a provided at the bottom of the heat pack 21, and an upper portion thereof. A check valve 22b for discharge, and a heating element 23 embedded in the heat pack 21 and wrapped in a wrap 24 in which water is absorbed. The opening and closing plate 25 and the delay means 26 are further provided at 22a.

The heating element 23 emits heat by chemically reacting with water introduced through the inflow check valve 22a. As the heating element 23, sodium (Na), calcium (Ca), and magnesium (Mg) compounds which are group 1 and group 2 elements are used. Typical examples include lime, sodium hydroxide, sodium acetate, and the like. In the case of lime mixed with iron, it reacts with water to give off heat of 60 ~ 90 ℃.

The heat generated by the heating element 23 is transmitted to the body through the heating pack 21 and the vest body 10, as described above, the temperature directly transmitted to the body is about 40 ℃.

It is preferable that the exothermic action by the heating element 23 lasts for a long time. To this end, the inlet (h) of the inlet check valve 22a is provided with an opening and closing plate 25. The opening and closing plate 25 opens and closes the inlet port h by the pressure of the reactant (normal gas) generated by the reaction of the heating element 23 and water. That is, normally, the inlet (h) is opened to allow water to flow in, and when the heat pack 21 expands more than a predetermined time by the reaction of the introduced water and the heating element 23, the inlet (h) is closed and no longer. The exothermic reaction is stopped by preventing water from flowing in, and the reactant is discharged through the discharge-only check valve 22b to open the inlet h again when the expanded heating pack 21 is contracted to a predetermined level or more. In this way, the opening and closing plate 25 intermittently regulates the inflow of water, so that the heat generation action by the heating element 23 lasts for a long time.

And the inlet (h) of the inlet check valve (22a) is provided with a delay means (26). The retardation means 26 is intended to allow water to flow into the heat generating pack 21 after a predetermined time after the heat generating means 20 contacts the water. The initial one or two hours when a distress is drowning can keep his own temperature. Therefore, it is preferable to allow the heating element 23 to exothermic from the time when it is difficult to maintain the body temperature by the distress himself.

In the present invention, a water-soluble substance (solid) dissolved in water is used as the delay means 26. That is, the inlet port h of the check valve 22a exclusively for inflow with water-soluble substances such as alum, salt and sugar was blocked to a predetermined thickness. Therefore, when the distress falls into the water, the water-soluble substance gradually starts to melt, and after a predetermined time (1 to 2 hours), the water is completely dissolved and water is introduced into the heat pack 21.

In the above, the heating means 20 for maintaining the body temperature of the distressed drowned for a long time to survive until rescue was described. Hereinafter, the location tracking terminal 30 and the night light emitting means 40 for quickly and accurately finding the distress will be described.

The position tracking terminal 30 is operated by the detection sensor in contact with the water or by the operation of the distress, ships, aircraft, search platform, etc. that are paying attention to the pre-stored rescue signals (eg SOS, MAY DAY) It transmits by the receiver or GPS satellite which are equipped.

The receiver receiving the rescue signal from the location tracking terminal 30 informs the position of the distress through hearing and vision,

When a plurality of GPS satellites receive a rescue signal, the position of the distress is accurately determined within a few meters of error by coordinate calculation, and the identified position of the distress is provided with an electronic map to The same officials can find out the location of the distress through a display device such as the Internet or a mobile phone, or even watch a video when using satellite DMB.

In addition, the position tracking terminal 30 is preferably controlled so that the rescue signal is periodically transmitted so that power consumption of the battery is reduced, and the upper portion of the collar portion 13 or the front portion 11 of the vest body 10. It is desirable to mount it so that it does not come into contact with water.

The night light emitting means 40 is a means for easily identifying the distress at night. Flash flares are a very effective means of indicating the location of the distress at night, but in terms of brightness and distance, but flare flares are short-lived, short-lived and rarely carried by the distress. Have

Therefore, another night light emitting means 40 should be considered. In FIG. 1, it can be seen that the light emitting tape 40 is attached to the front part 11, the rear part 12, and the collar part 13 by night light emitting means 40. The light emitting tape 40 does not emit light during bright day, but emits light at night, and emits a large amount of light so that it can be distinguished from a distance when absorbing even a little light at night. In addition, although not shown, an LDP light emitting device including a battery, a light emitting lamp, and a switch may be used as a night light emitting means.

And the vest main body 10 may be equipped with an RFID (Radio Frequency Identification) card 50 that stores the personal information of the distress. The RFID card 50 stores information on the nationality, name, address, contact information, etc. of the distress, so that even if the distress is unconscious at the time of rescue, the identity card can be immediately identified to take follow-up measures.

In the above description of the present invention, a life jacket having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention can be variously modified and changed by those skilled in the art, and such modifications and changes are the protection of the present invention. Should be interpreted as being within the scope.

As described above, the present invention maintains the body temperature of the distress who is drowned for a long time and enables the distress to survive until the rescue of the distress.
