Description

Heating expansion tube attachable to life jacket

The present invention relates to an exothermic expansion tube attachable to a life jacket.

In general, life jackets are equipment for floating the wearer in water using their own buoyancy, and are worn by occupants of ships or boats in preparation for water disasters, or to safely float inexperienced swimmers in water.

In recent years, as water leisure sports have become increasingly popular, they are also used when using water skiing and water playground equipment to prevent the occurrence of water safety accidents in advance.

The conventional life jacket is roughly divided into a method in which a tube is provided in the space between the inner skin and the outer skin, and air is injected there, and a buoyancy material made of a foamed resin is installed between the inner skin and the outer skin.

However, when a person is in contact with water for a long time while wearing a life jacket, it becomes difficult to perform normal activities as the body becomes hypothermic because the water temperature is lower than body temperature.

Here, hypothermia means that the body temperature is below 35°C, and under hypothermia, mental function is slowed, muscle strength is lost, pulse and respiration are weak, blood pressure is lowered, and in severe cases, a coma falls into life. will lose

In particular, due to the nature of the place where marine accidents occur, realistic difficulties arise in saving lives, and delays in rescue lead to deaths due to drowning and hypothermia.

However, there is a problem in that the conventional life jacket only reduces the risk of drowning and cannot prevent hypothermia.

Accordingly, the present applicant has developed a heating life jacket capable of preventing hypothermia with heat by expanding in volume due to heat generated by reacting with water and adhering to the wearer's body.

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

1 and 2 show a heating expansion tube attachable to a life jacket according to an embodiment of the present invention.

As shown in these drawings, the heat-generating expansion tube attachable to the life jacket according to an embodiment of the present invention is detachable from the heat-generating expansion tube 30 in the normal life jacket 1 .

The life jacket body 10 forming the appearance of the life jacket 1 is composed of a front portion 11 covering the chest and abdomen, and a shoulder portion 13 covering the shoulder from the back of the neck. A detachable means 15 is provided on the front part 11, and the detachable means 15 may include a fastener, Velcro cloth, a buckle, a button, a zipper, and the like.

In addition, the life jacket body 10 includes an outer shell (not shown) and an inner shell 19, and is made of a waterproof material that does not penetrate rain, snow, sea water, and the like.

On the other hand, a buoyancy material (not shown) may be put into the space between the endothelium 19 and the outer skin. The buoyancy material has a lower specific gravity than water and is made of a lightweight foam resin that acts as a buoyant force. The buoyancy force is primarily applied to the life jacket (1).

Here, instead of the buoyancy material in the space between the inner shell and the outer shell of the life jacket body 10, an air-injected tube may be provided.

The heating expansion tube 30 is provided detachably on the endothelium of the life jacket body 10 . The heating expansion tube 30 expands in volume by the heat generated by the heating agent, and is in close contact with the body of the wearer 100 .

The heating expansion tube 30 includes an expansion tube body 31 , a heating pack 41 , a heating pack cover 45 , and an inlet hole cover 51 .

The expansion tube body 31 accommodates the heating pack 41 and is detachably attached to the inner skin of the life jacket body 10 .

The expansion tube body 31 has a sealed hollow barrel shape. The expansion tube body 31 has a chamber 33 in which air circulates and flows. In addition, the heating pack 41 is accommodated in the chamber 33 .

The expansion tube body 31 is capable of volume expansion by the heat generated by the heat generating agent, and is made of a material having elasticity and waterproofness. Preferably, it may be made of a PVC material having excellent elasticity and waterproofness.

In addition, the expansion tube body 31 of the exothermic expansion tube 30 according to an embodiment of the present invention has a bellyband shape disposed along the circumference of the body of the wearer 100 . Here, in the present embodiment, the exothermic expansion tube 30 is illustrated as having a bellyband shape, but is not limited thereto, and the exothermic expansion tube 30 may have various shapes.

The heating pack 41 has a pack shape and seals and accommodates the heating agent. The heating pack 41 is accommodated in the chamber 33 and is attached to one surface of the expansion tube body 31 to be described later by the heating pack cover 45 .

The heating pack 41 serves as a medium for the heating agent to absorb and deliver water necessary for the heating action. Accordingly, the heating pack 41 absorbs moisture well and may be made of a material that is not easily torn or deformed when in contact with water, for example, a cotton fabric or a non-woven fabric.

The exothermic agent may use a powdery compound that chemically reacts with water to generate heat. The exothermic agent may include at least one of calcium oxide, aluminum, sodium carbonate, sodium hydroxide, calcium carbonate, and sodium bicarbonate. Here, since the technique in which the exothermic agent reacts with water to generate an exothermic action is already known, a detailed description thereof will be omitted. Meanwhile, the heating pack 41 may set the heating time and heating temperature in various ways by adjusting the composition ratio of the mixed compound constituting the heating agent.

The heating pack cover 45 is made of a waterproof material, and is attached to the expansion tube body 31 to cover the heating pack 41 .

An inlet hole 47 for supplying water to the heating pack 41 accommodated in the chamber 33 is formed in one region of the heating pack cover 45 . The inlet hole 47 is covered by the inlet hole cover 51 .

The inlet hole cover 51 has a thin sheet shape and is attached to the heating pack cover 45 to cover the inlet hole 47 .

The inlet cover 51 is made of a material in which a plurality of ventilation holes (not shown) are formed. The inlet cover 51 is coated with a water-soluble coating agent that dissolves when in contact with water.

Here, the inlet cover 51 may be made of a non-woven fabric, and the water-soluble coating agent may include starch, glycerin, and gelatin.

Accordingly, the inlet hole cover 51 blocks the inlet hole 47 so that foreign substances do not flow into the heating pack 41 through the inlet hole 47 in normal times. On the other hand, when the inlet cover 51 is in contact with water, the water-soluble coating agent of the inlet cover 51 is dissolved and the inlet hole 47 is opened.

The heating pack 41 and the heating expansion tube 30 including the expansion tube body 31 and the inlet hole cover 51 are attached to and detached from the inner skin of the life jacket body 10 by a detachable means 60 .

In this embodiment, as the detachable means 60, the inner shell 19 of the life jacket body 10 and the heat-generating expansion tube 30 are each provided with a Velcro cloth in one area in contact with each other.

Here, instead of the Velcro cloth as the detachable means 60, a double-sided tape, a snap button may be provided.

In addition, although the exothermic expansion tube 30 in this embodiment is shown to be detachable by the detachable means 60 on the inner skin of the life jacket body 10, the exothermic expansion tube 30 is the life jacket body 10. It is not detachable from the endothelium of the wearer 100 , and may be worn alone on the body of the wearer 100 .

Accordingly, the exothermic expansion tube 30 expands in volume by the heat generated by the chemical reaction of water and the exothermic agent, so that the buoyancy force is secondarily applied to the exothermic life jacket 1 according to an embodiment of the present invention.

By this configuration, when the wearer 100 wears the life jacket 1 attached to the endothelium of the life jacket body 10 by the detachable means 60 before the wearer 100 obtains, FIG. 3, FIG. As shown in (a) of 5 and 6, the heating expansion tube 30 has a volume-reduced state, and does not adhere to the abdomen of the wearer 100.

On the other hand, if you get into water after wearing the life jacket 1 to which the exothermic expansion tube 30 is attached according to an embodiment of the present invention, the inlet cover 51 of the exothermic expansion tube 30 is caused by water. As it dissolves, the inlet hole 47 is opened.

Then, the water introduced through the inlet hole 47 chemically reacts with the heating agent of the heating pack 41 to generate heat in the heating pack 41 .

At this time, the air accommodated in the chamber 33 of the expansion tube body 31 is heated by the heat generated by the heat generating pack 41, and as shown in FIGS. The tube 30 expands in volume, surrounds and adheres to the body and abdomen of the wearer 100 , and at the same time, buoyancy is additionally generated by the expanded heating expansion tube 30 . Here, the heating expansion tube 30 may be worn on the chest to surround the heart of the wearer rather than the abdomen of the wearer, as shown in FIG. 8 .

In addition, the heated air of the chamber 33 circulates through the chamber 33 and uniformly heats the expansion tube body 31 .

Then, as water gradually flows into the chamber 33 of the expansion tube body 31 through the inlet hole 47, the water introduced into the chamber 33 by the heating pack 41 and the already heated air is heated or steamed. The heat-generating expansion tube 30 due to the heated water and steam increases the heat retention time, and it is possible to minimize heat loss.

Accordingly, by heating the body of the wearer 100 in close contact with the expansion tube body 31, the body temperature can be efficiently maintained for a long time, and hypothermia can be prevented.

On the other hand, the inlet hole cover 51 is made of a nonwoven fabric material that is wetted with water, so water can easily flow in, but the gas of the chamber 33 cannot easily escape due to the wet nonwoven fabric. Rather, since the chamber 33 is not completely sealed by the dissolved inlet hole cover 51 , gas may escape through the inlet hole 47 , but rather water vapor generated in the chamber 33 due to this action. This prevents the exothermic expansion tube 30 from being excessively inflated and bursting. In addition, since the inlet hole 47 is lower than the water surface in the water, the gas in the chamber 33 of the expansion tube body 31 cannot easily escape.

As such, according to the present invention, when a wearer wearing a life jacket with a heating expansion tube according to an embodiment of the present invention falls into the water, the primary buoyancy is applied to the wearer by the buoyancy material of the life jacket body. And, the water introduced through the inlet hole of the heating expansion tube reacts with the heating agent of the heating pack, and the air in the expansion tube body expands by the heat generated by the heating agent, and the heating expansion tube expands, giving the wearer a secondary buoyancy. In addition to the action, the wearer's body is heated, preventing hypothermia and maintaining body temperature efficiently for a long time.

In addition, by attaching and detaching the exothermic expansion tube to the inner skin of the life jacket body by a detachable means, it can be detached and used regardless of the size and type of the conventional life jacket. be able to do

As mentioned above, although embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art to which the present invention pertains can realize that the present invention can be embodied in other specific forms without changing the technical spirit or essential features thereof. you will be able to understand Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
