Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifesaving vest worn by occupants of a ship.

[0002]

2. Description of the Related Art As a countermeasure against a marine accident, occupants of a ship wear marine life jackets. A conventional lifesaving vest is made of a foamed resin or the like, and can be floated on the sea if worn. The rescue squad
They are rushed to the marine accident site by radio notification from a marine vessel and rescue them.

[0003]

However, the conventional lifesaving vest made of foamed resin is so thick and lacks flexibility that it is difficult to wear it, so that seamen and others tend to avoid wearing it. It is also extremely difficult for rescue squads to quickly find victims in a wide range of marine areas with many salmon, and rescuers often fail due to their late detection.

[0004] Accordingly, an object of the present invention is to provide a lifesaving vest which is easy to be worn by an occupant even in normal times and has excellent wearability. Another object of the present invention is to provide a lifesaving vest that enables a rescue team to quickly find a victim in the event of a marine accident.

[0005]

The salvage vest of the present invention has a bag-like structure, and a gas cylinder for supplying gas into the bag-like structure, and an operation unit for operating gas ejection from the gas cylinder. It is provided with.

[0006] Therefore, in normal times, the lifesaving vest is thin, like a general vest, and fits easily to the body, so that it is easy to wear. Then, when the operation unit is operated at the time of a marine accident, the gas in the gas cylinder is squirted into the marine life jacket and the inside is filled with the gas, and the marine life jacket is inflated into a floating bag.

A second gas cylinder, a second operation section for operating gas ejection from the second gas cylinder, and a lightweight gas ejected from the second gas cylinder are provided in the sea lifesaving vest of the first aspect. It is provided with a collapsible balloon to be supplied and a marine alert device consisting of a rope connecting the balloon and a life jacket.

[0008] Therefore, a victim floating on the sea due to a marine accident operates the second operation unit. Then, the lightweight gas is sent from the second gas cylinder to the balloon, and the balloon is inflated, rises and floats in the air. Desirably, the balloon is made of a light-emitting material such as a bright color such as yellow or a fluorescent material that shines at night. Then, the rescue squad rushed near the scene can easily find the victim by witnessing this balloon.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a victim during a marine accident, FIG. 2 is a front view of a marine life jacket, FIG. 3 is a partial cross-sectional view of the marine life jacket, and FIG.

FIG. 1 shows a state in which a victim who has been thrown into the sea due to a maritime accident raises a balloon of a maritime accident report device (described later) into the air and waits for the arrival of a rescue squad. The victim is wearing a lifesaving vest 1. The salvage jacket 1 and the balloon 15 are connected by a rope 18. The length of the rope 18 is, for example, about 5 m, and the diameter of the balloon 15 is, for example, about 1 m. The balloon 15 is desirably made of a color that is easily detected by the rescue team, for example, a light color such as yellow or red, or a light-emitting material such as a fluorescent material that is easily visible at night. The rope 18 is desirably a resin string or the like. In the present invention,
"Rope" refers to slender string-like members such as resin strings
Collectively.

FIG. 2 is a front view of the lifesaving vest 1 having a pocket 2 provided on its chest. FIG. 3 (a),
In (b), the lifesaving vest 1 has a double or multiple bag-like structure sealed with an air-impermeable sheet (cloth) such as a synthetic resin sheet, and a gas cylinder 3 is provided at an arbitrary position such as a lower portion thereof. (See also FIG. 2).
The gas cylinder 3 contains a gas such as carbon dioxide. Reference numeral 5 denotes an operation unit of the gas cylinder 3,
It is exposed outside. Normal (normal), FIG. 3 (a)
As shown in the figure, the lifesaving vest 1 is deflated, and is therefore thin, easy to fit to the body, and easy to wear on the body because of its high flexibility. Can be worn.

When the operation unit 5 is operated by pulling it down by hand, the gas in the gas cylinder 3 is blown out from the nozzle 4, and the blown out gas inflates the lifesaving vest 1 (FIG. 3).
(B)). Therefore, if a marine accident occurs,
By operating the operation unit 5, the lifesaving vest 1 becomes a bladder.

In the pocket 2 of the marine life jacket 1, a marine accident reporter comprising the following elements is stored. FIG.
4 and FIG. 4, reference numeral 11 denotes a second gas cylinder,
Ejects lightweight gas. Light gas is lighter than air,
A gas floating in the air, for example, helium gas. The second gas cylinder 11 is attached to the lifesaving vest 1 by attaching means (not shown) such as a flocking band. At the lower end of the string 12 hanging from the second gas cylinder 11, a lever as a second operation unit is mounted.
The lever 13 is exposed and hanging outside the pocket 2,
When this is manually operated by pulling it downward, light gas is ejected from the second gas cylinder 11.

A tube 14 extends from the second gas cylinder 11. Reference numeral 15 denotes a balloon, from which a tube 16 extends. The tubes 14 and 16 form a gas supply path. Tube 1 in the middle of gas supply path
The lower end of 6 is connected to the distal end of the tube 14 so that it can be inserted and removed (removably). Balloon 15 and tube 1
6 is connected via a check valve portion 17. The balloon 15 and the lifesaving vest 1 are connected by a rope 18.
The lower end of the rope 18 is attached to the inside of the pocket 2 by a seat 19.

In FIG. 2, the balloon 15 is freely foldable, folded small, and stored in the pocket 2. In the pocket 2, the second gas cylinder 11
Is at the bottom and has a rope 18 on the second gas cylinder 11
The balloon 15 is folded and stored on the rope 18.

The marine life jacket is constructed as described above. If a marine accident occurs, the wearer operates the operation unit 5 to expand the marine life jacket 1 as shown in FIG. 3 (b). To make a bladder. In addition, a victim thrown into the sea due to a maritime accident pulls the lever 13 downward. Then, lightweight gas is supplied from the second gas cylinder 11 to the balloon 15,
The balloon 15 expands and rises into the air. Therefore, the rescue squad can easily find the victim by searching for the balloon 15.

When the balloon 15 is inflated and rises into the air, the tube 16 comes out of the tube 14 and is separated. Also, the leakage of the light gas from the balloon 15 is prevented by the check valve portion 17, so that the balloon 1
5 can maintain the expanded state. The tube 14,
Instead of 16, the balloon 15 and the second gas cylinder 11 may be connected by one long tube similar to the rope 18, and in this case, the check valve portion 17 is not necessarily required. However, as in the present embodiment, the second gas cylinder 1
One side tube 14 and balloon 15 side tube 16
If the balloons 15 are automatically separated by the floating force when the balloon 15 floats, the total length of the tubes 14 and 16 can be shortened. Of course, the specific means for separating the tube on the side of the second gas cylinder 11 and the tube on the side of the balloon 15 is not limited to the above embodiment.
May be detachably connected by a joint that can be separated by the above-mentioned floating force.

[0018]

As described above, according to the present invention, it is possible to realize a lifesaving vest which is easy for a passenger to wear even in normal times. Also, the victim can raise the balloon into the air by the second gas cylinder, so that the rescue team can easily find the victim from a distance.
