  However, the conventional life-saving device has a problem that when it comes into contact with drifting objects such as debris, metal pieces, and wood in the event of a flood, a hole is opened in the life-buoy body, and gas leaks and the function as a life-saving device is not exhibited.

  The life-saving device according to the present invention has been made in view of the above-mentioned problems, and the problem to be solved by the present invention is to provide a function as a life-saving device even if a hole is opened in the lifebuoy body and gas leaks. It is to provide a lifesaving device that can.

  The present invention is a lifesaving device, and includes a jacket, a plurality of independent airbags provided in the jacket, and an operation unit that supplies gas to the airbag. The jacket includes a jacket in which a chest and abdomen are formed with a pair of storage portions that can store water or emergency food. Further, the jacket material includes those formed of urethane foam. A connecting portion that defines the position of the airbag is disposed between adjacent airbags, and the entire body of the wearer is covered from the outside by the airbag and the connecting portion when the airbag is inflated.

  Since the lifesaving device according to the present invention includes a plurality of independent airbags in the jacket, buoyancy can be obtained from each airbag. Therefore, the function as a life preserver is not impaired unless all the airbags are damaged. For example, when the life-saving device according to the present invention is worn and the surface of the water is floated in the event of a flood, even if a part of the air bag provided on the jacket breaks due to contact with a drifting object and gas leaks, the remaining The buoyancy can be obtained from the air bag, and it can float on the water surface.

  Since the said jacket is formed with the accommodating part which can accommodate water or an emergency food, for example, a plastic bag and a small bag containing food can be accommodated. Therefore, even if the period until rescue is long, life can be extended by ingesting water or emergency food.

  Furthermore, since the said jacket is formed with the foaming urethane raw material, it exhibits the heat insulation effect. That is, when the wearer wears the jacket, the body heat of the wearer inside the jacket can be stopped. Therefore, since the jacket formed of the urethane foam material has excellent body temperature heat retention, the body temperature can be prevented from decreasing even if it is immersed in water for a long time, and the life can be prolonged.

  In addition, since the connecting portion that defines the position of the air bag is disposed between the adjacent air bags, when the air bag expands and spreads, the position of the air bag is stabilized, and the air bag and the connecting portion Since the wearer's whole body is covered from the outside, the wearer can be more effectively protected from debris and the like.

It is a front view of the life preserver concerning the present invention. It is a rear view of the life preserver concerning the present invention. It is an expanded view showing the connection state of the air bag with which a jacket is provided, a gas cylinder, and an action | operation part. It is a front view showing the use condition of the life preserver concerning the present invention.

  As shown in FIG. 1, a life preserver 1 according to the present invention includes a vest type jacket 2 worn on a trunk, and a sliding fastener 6 for opening and closing the jacket is provided at the front center of the jacket 2. Yes. A pair of storage portions 4 a and 4 b that can store drinking water, emergency food, and the like are formed on the chest and abdomen of the jacket 2. Moreover, the accommodating part 4b is equipped with the slide type fastener 4c in the upper end. As shown in FIG. 1, it is desirable that the operating unit 5 described below is protruded from the lower end of the jacket 2 to the outside as long as it can be manually operated.

  As shown in FIG. 2, the lifesaving device 1 according to the present invention includes a plurality of independent airbags 3 on the back surface of the jacket 2. The air bag 3 is folded and stored in a predetermined position as shown in FIG. 2 until it is actually used. Adjacent airbags 3 are connected by a connecting portion 3a. The connecting portion 3a is formed in a film shape, for example, and is stored in a folded state. A gas cylinder 8 that stores compressed gas and supplies the compressed gas to the airbag 3 is disposed at the lower part of the back surface of the jacket 2. The gas cylinder 8 includes a gas supply unit 9 at the top thereof.

  As shown in FIG. 3, the airbag 3 is connected to a gas introduction pipe 11 through a check valve 10 for preventing gas from flowing out of the airbag 3. One check valve 10 is connected to each gas introduction pipe 11 for each airbag 3. The plurality of airbags 3 are arranged in parallel with each other being independent. In addition, an operation unit 5 for supplying compressed gas to the airbag 3 is connected to the gas supply unit 9 of the gas cylinder 8.

  When the jacket 2 according to the present invention is used, when the operation unit 5 is operated, the gas supply unit 9 opens, the supply of the compressed gas is started, and the compressed gas is directed in the direction in which the check valve 10 faces the airbag 3. Passed through and compressed gas is introduced into an independent air bag 3. As a result, the pressure inside the airbag 3 filled with the compressed gas rises, and the airbag 3 enters an inflated state.

  As a result, as shown in FIG. 4, the air bag 3 protrudes outward from the position stored on the back surface of the jacket 2. Accordingly, the inflated airbag 3 is positioned near the neck, both shoulders, both arms, and the waist of the wearer A according to the accommodation position on the back surface of the jacket 2, and has a balloon shape as shown in FIG. Therefore, even when the wearer A wears the jacket 2 and actually falls, the air bag 3 can float on the water surface without being submerged by the buoyancy of the airbag 3. And the wearer A can maintain the stable floating state on the water surface, and can wait for rescue. Moreover, since the connection part 3a is arrange | positioned between the adjacent airbags 3, when the airbag 3 expand | swells and spreads, the position of the airbag 3 will be prescribed | regulated by the connection part 3a. Therefore, the position of the airbag 3 is stabilized, and the entire body of the wearer A is covered from the outside by the airbag 3 and the connecting portion 3a, so that the wearer A can be protected from debris and the like.

  As shown in FIG. 4, when the jacket 2 is actually used, it is desirable that the wearer A wears the jacket 2 by sliding the sliding fastener 6 to the neck portion 7. When water falls in a state where the front surface of the jacket 2 is opened, water enters the inside of the jacket 2 and the jacket 2 is easily removed, so that the wearer A cannot sufficiently maintain a stable floating state on the water surface. Moreover, in the state where the front surface of the jacket 2 is opened, water directly contacts the body of the wearer A, so that the heat insulating effect of the lifesaving device according to the present invention is not exhibited, and the body heat of the wearer A inside the jacket 2 is retained. It is difficult to prevent a decrease in body temperature. Therefore, it is desirable to slide the slide type fastener 6 to the neck portion 7.

  As shown in FIG. 4, the accommodating portion 4 a in a state where the jacket 2 is worn is located on the chest of the wearer A, and the accommodating portion 4 b is located on the abdomen of the wearer A. Since both are located in the range where the hand of the wearer A can reach, it is possible to take drinking water and emergency food as contained matter without difficulty. If drinking water and emergency food are stored in the storage portions 4a and 4b, the wearer A can prolong the life by ingesting the drinking water and emergency food even in the case of water shortages. Since the accommodation portion 4b is provided with the slide fastener 4c, it is desirable to close the slide fastener 4c so as not to lose the contents.

  When the jacket 2 is in use, a part of the air bag 3 provided independently of the jacket 2 comes into contact with the debris such as debris, the air bag 3 breaks, a hole is opened, and gas leaks. Buoyancy cannot be obtained from the damaged airbag 3. However, each of the airbags 3 provided in the jacket 2 is connected to the gas introduction pipe 11 via the check valve 10 and is arranged in parallel in an independent state. Even if the air bag is broken, there is no effect on the remaining airbag 3 that is not in contact with the drifting object, and no gas leaks from the remaining airbag 3. Accordingly, buoyancy can be obtained from the remaining airbag 3, so that the floating state on the water surface can be maintained. Thus, in the present invention, even when a hole is opened in the air bag of the life preserver and gas leaks, the function as a life preserver can be exhibited.

  If the period until the wearer A is rescued is prolonged, the survival rate is lowered. Therefore, the jacket 2 is preferably formed of a material that is optimal for maintaining body temperature. The jacket 2 is formed of foamed urethane. Therefore, a heat insulation effect is exhibited and the body heat of the wearer A can be kept inside the jacket 2. Therefore, the urethane foam jacket 2 is suitable for maintaining body temperature.

  In the said embodiment, although the airbag 3 showed the type which supplies compressed gas from the gas cylinder 8, it is not limited to this. As another embodiment, the life preserver includes a gas generator (inflator) and a gas generating agent. Thus, it is one of the preferred embodiments of the present invention that the gas generator is ignited and the gas generator is used to supply gas by explosion of the gas generating agent.
