1 is a view showing in cross section an embodiment of the life jacket disclosed in the present specification. Figure 2 is a view showing an embodiment of the life jacket disclosed in the present specification.

The life jacket disclosed herein may include a vest 100 having a large buoyancy and a floating buoyancy unit 200 having buoyancy by introducing air between the vest 100 and the wearer.

The floating buoyancy unit 200 is provided as a ring-shaped tube surrounding the wearer's neck, the lower part is cut in the longitudinal direction, and the side that does not contact the wearer's neck is combined with the vest 100 and the vest ( 100) and the space between the wearer and the inner space of the tube may include a connection.

The vest 100 may include an outer skin 101 and an endothelium 103 and a space 105 between the outer skin 101 and the endothelium 103, and a heating unit 130 that generates heat in the space. .

The vest 100 may include a location tracking unit (not shown) disposed in the space 105 to track the wearer's location.

The life jacket disclosed herein with reference to FIG. 1 may largely include a vest 100 and a floating buoyancy unit 200 .

The vest 100 may be provided as a general lifesaving garment with buoyancy. The vest 100 is largely provided with an outer skin 101 and an endothelium 103 , and a space 105 may be provided between the outer skin 101 and the endothelium 103 . The space 105 may be filled with buoyancy, such as Styrofoam or air. The vest 100 may be provided in the same shape as a vest found in general clothing.

The endothelium 103 is a surface that comes into contact with the body of the life jacket wearer. The outer shell 101 is a surface in contact with the outside when the life jacket is worn. The shell 101 and the endothelium 103 may be connected to each other to form a space 105 between the shell 101 and the endothelium 103 . In addition, when the wearer of the heating vest 100 falls into water, the outer shell 101 and the endothelium 103 are, for example, to prevent water from penetrating into the space 105 between the outer skin 101 and the endothelium 103 . For example, it may be composed of a waterproof material such as neoprene waterproof fabric, which is a wetsuit material.

On the other hand, the endothelium 103 may be provided with a material with good efficiency in maintaining body temperature.

On the other hand, in the vest 100, a space is inevitably formed between the wearer's skin and the endothelium 103 .

The floating buoyancy unit 200 may be provided so that air between the vest 100 and the wearer is introduced to have buoyancy. In more detail, the floating buoyancy unit 200 may be provided as a ring-shaped tube surrounding the wearer's neck. The flow buoyancy unit 200 may have a lower portion of the tube cut in the longitudinal direction. In the flow buoyancy unit 200, one side of the tube based on the incision is in contact with the wearer's neck. One side of the floating buoyancy unit 200 that does not come into contact with the wearer's neck may be coupled to the vest 100 . The floating buoyancy unit 200 connects the space between the vest 100 and the wearer and the inner space of the tube. That is, the floating buoyancy unit 200 is such that when the wearer enters the water, the air existing in the space between the vest 100 and the wearer moves to the wearer's neck, so that the tube expands to generate buoyancy. When the wearer comes out of the water, the flow buoyancy unit 200 naturally moves the air present in the tube to the outside, so that the wearer may naturally move the neck.

On the other hand, the flow buoyancy unit 200 may further include another conventional tube on one side in contact with the wearer's neck. When wind is injected into the other tube, the tube expands and one side of the floating buoyancy unit 200 is brought into close contact with the wearer's neck to prevent the air in the space between the vest 100 and the wearer from leaking to the outside, It is also possible to provide a seal that conforms to the wearer's body type.

The vest 100 according to another exemplary embodiment with reference to FIG. 2 may further optionally include a battery unit 110 and a heating unit 130 .

The battery unit 110 generates electric power by using the temperature difference between the outer shell 101 and the inner shell 103 . For example, the battery unit 110 measures the difference between the temperature of the inner skin 103 raised due to the wearer's body temperature and the temperature of the outer skin 101 lowered due to external (eg, air, river water, sea water, etc.) factors. It may include a thermal cell that generates electric power by using it. In this case, the thermo cell may be, for example, a liquid thermo cell. The battery unit 110 may be disposed in the space 105 . The battery unit 110 may include a plurality of thermal cells each generating electric power according to a temperature difference between the outer shell 101 and the inner shell 103 . The battery unit 110 may be disposed on the rear portion of the vest 100 in which a relatively wide portion is in contact with the wearer in order to effectively use the temperature of the endothelium 103 raised by the wearer's body temperature for power generation. The battery unit 110 may include a plurality of thermal cells having a small size or a single thermal cell having a large size. In this case, the plurality of thermo cells may be connected in series or in parallel.

The heating unit 130 is disposed in the space 105 between the shell 101 and the endothelium 103 to generate heat by the electric power generated by the battery unit 110 . Specifically, the heating unit 130 may generate heat by using the power generated by the battery unit 110 , and transfer the generated heat to the endothelium 103 . That is, when the wearer falls into water, the battery unit 110 generates power according to the temperature and transmits it to the heating unit 130 , and the heating unit 130 generates heat according to the transmitted power, so that the wearer's passive Heating function can be performed automatically without operation.

On the other hand, the life jacket disclosed herein may optionally further include a location tracking unit (not shown) and a communication unit (not shown).

A location tracking unit (not shown) may be disposed in the space 105 between the outer shell 101 and the endothelium 103 to track the wearer's location. The location tracking unit (not shown) is disposed in the space 105 between the outer shell 101 and the endothelium 103 to receive power from the battery unit 110 to operate. In this case, the location tracking unit (not shown) may be, for example, a location tracking device such as a GSP module.

The communication unit (not shown) is disposed in the space 105 between the outer skin 101 and the endothelium 103, and transmits at least one of the state of charge of the battery unit 110 and the wearer's location information to a preset device. . Specifically, the communication unit (not shown) may receive information on the state of charge from the battery unit 110, receive the wearer's location from the location tracking unit (not shown), and transmit this information to a preset device. . In this case, the preset device may be, for example, a preset person's portable device, a reception device of the 119 safety report center, a reception device of the marine rescue team, and the like.

In addition, the communication unit (not shown) is disposed in the space 105 to receive power from the battery unit 110 to operate. That is, when the wearer falls into the water, the battery unit 110 generates power according to the temperature and transmits it to the location tracking unit (not shown) and the communication unit (not shown). Accordingly, the position tracking unit (not shown) tracks the position using a GPS module or the like, and the communication unit (not shown) transmits the wearer's position, thereby facilitating the structure.

Although it has been described in detail with respect to the life jacket disclosed in the present specification through the representative embodiment above, those of ordinary skill in the art to which the life jacket disclosed in the present specification belongs will use the life jacket disclosed in the present specification with respect to the above-described embodiment. It will be understood that various modifications are possible without departing from the scope. Therefore, the scope of rights of the life jacket disclosed in the present specification should not be limited to the described embodiment, and should be defined by the claims described below as well as the claims and equivalents.
