Abstract

PURPOSE:To improve safety by providing a float with control function so that it can be expanded through automatical gas filling during immersion to keep a breathing means for a lifesaving wearer in the attitude of being held in the atmosphere. CONSTITUTION:An expansion float 7 is connected to an automatical gas filling device through a tube 9. When a wearer is thrown into water and gas is automatically filled in the float 7, a face bed fastener or push bottom mounted on the soft cover 4 of a lifesaving tool Y is separated off by the expansive force of the float 7, so that the expanded float 7 is put at his jaw or at high mouth around the face cover 2d of a helmet 2 without choking his neck. As a result, a floater's face is kept standing and his mouth and nose, being always on the water level, are kept in a respirable situation. It is thus possible to improve safety.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a catfish life preserver.

(Prior Art) FIG. 3 is a side view showing a state in which a conventional lifesaving device is attached.

In drawing 3, 1 is a human being, 1a is a head, 2 is a helmet, 2d is a face cover of the helmet, and 3 is a known solid life jacket.

When working on the water, such as motorboat racing, wear a solid life jacket or an inflatable life jacket (not shown).
In the event of an accident, it is common practice to help save lives.

(Problems to be Solved by the Invention) As described above, in the conventional example, in a motorboat race on the water, it goes without saying that people compete for speed, but competing for speed causes them to become overly conscious, and to fight with fellow boats or others. Collisions with objects can cause people to be thrown over the water. If there is human consciousness at that time, the third
As shown in the figure, people's lives can be saved because they are wearing solid life jackets. However, in the event of a collision or being thrown, the person may become unconscious and die.

Conventionally, as shown in Figure 3, people participating in motorboat races wear life jackets with a buoyancy that is thicker than normal life jackets for safety reasons, such as to prevent injury to the human body from the propellers of boats, and to reduce the impact force caused by collisions. A person is wearing a solid type life jacket and a helmet, but if the person becomes unconscious during a collision or is thrown, the weight of the helmet and the person will be The problem is that the natural movement of the animal's neck causes its face to fall forward and hit the water surface, making it difficult to breathe and causing water to be inhaled into the lungs, resulting in death.

This invention was made to solve the above-mentioned problems.The floating body is inflated by a known gas filling device that automatically operates when immersed in water, and the breathing means of the life jacket wearer is removed from the atmosphere. The aim is to develop a life-saving device that can save human lives by demonstrating the posture control function that is maintained in the body.

[Means for Solving the Problems] Therefore, the present invention includes a life jacket main body, a floating body having an attitude control function that maintains the breathing means of the life jacket wearer in the atmosphere when inflated underwater; The object is to be achieved by a lifesaving device equipped with an automatic gas filling device that automatically operates to supply air to the floating body and inflate it when submerged in water.

(Function) The lifesaving device according to the present invention uses an automatic gas filling device to
Air is automatically supplied to the floating body to inflate it when submerged in water, and the floating body maintains the breathing means of the life jacket wearer in the atmosphere when the floating body expands in the water.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a front view showing a state in which a lifesaving device according to an embodiment of the present invention is attached, and FIG. 2 is a perspective view showing a state in which this embodiment is attached underwater.

In Figure 1 of the drawing, Y is a life preserver, 1 is a human being, 1 d is a head, 2 is a helmet attached to the head 1 d, 2 d is a face cover of the helmet, and 4 is a life jacket worn by a person wearing a life jacket when inflated in water. A soft cover houses an inflatable floating body 7 (FIG. 2) that has an attitude control function to keep the breathing means A in the atmosphere, and 5 is a belt (not shown) that stores the inflatable floating body 7 and the soft cover 4. ), etc., and is attached to the soft cover 4, and is a fixing belt for the life jacket, and is either removably tied to the solid life jacket, or fixed so as not to move using a face-to-face fastener, etc.

Note that the position shown in FIG. 1 is an example, and the position may be on the back side. In addition, the inflatable floating body 7 has a heavy air chamber or a multi-stage air chamber, and has a structure that fits in the chin area of a person without tightening the human neck when inflated, or the opening of the face cover of a helmet being worn. Fits in place,
Alternatively, it is configured to fit in the position of a human's chin and the mouth of the face cover of a helmet so that the human's mouth and nose can be kept in the atmosphere.

Reference numeral 9 denotes a tube extending from one end of the soft cover, which includes an inflatable floating body 7 and a known automatic gas filling device (not shown) that automatically operates to supply air to and inflate the floating body 7 when submerged in water. connected. Further, the tube 9 may be outside or inside the solid life jacket.

In addition, the automatic gas filling device operated by the action of water is installed near the inflatable floating body 7 by placing one part of the solid life jacket 3 in the vicinity of the inflatable floating body 7.
By providing the floating body 7 at a position that does not interfere with the operation of clothes or clothing, the inflatable floating body 7 attached to the chest area is made lighter and the operability of the body directly in front is improved.

Figure 2 of the drawing shows a state in which a person's mouth and nose, which are the means of breathing A, are held in the atmosphere underwater, 1d is the head, a helmet 2 is attached to the head 1d, and a solid lifesaving device is attached. vest 3
is attached. When the person is unconscious underwater, the head 1d is moved to the arrow 6 due to the weight of the helmet 2 and the natural movement of the person.
, and at the same time or before the mouth and nose become below the water level 8, the known gas filling device is activated by water, enters the inflatable floating body 7 through the tube 9, opens the soft cover 4, and inflates. The floating body 7 of the type is inflated, and as shown in FIG. 2, the breathing means A, which is the breathing means A, has a posture control function that keeps the nose and nose in the atmosphere, making it possible to breathe.

Although only one inflatable floating body 7 is visible in the figure, it can be used to connect the human chin area, the helmet face opening position 2C of the helmet face cover 2d, or the human chin area and the helmet face opening position 2c. For holding, a double or multi-layered inflatable floating body 7 may be used.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 and 2, focusing on the floating body 7.

Human 1 puts on a hard life jacket 3, wears a helmet 2, and ties the soft cover 4 of the life preserver Y of this embodiment to an appropriate position on the back from just in front of the hard life jacket using a string. Alternatively, it is fixed so that it does not move using a removable fixing belt 5 such as a face-to-face fastener. The pipe 9 is made of medium or high pressure, and connects a known water-operated automatic gas filling device (not shown) to the inflatable floating body 7. The air device is installed at the bottom of the solid life jacket in a way that does not obstruct operation and prevents water from splashing.Also, as is well known, the inflatable floating body 7 can be folded into the soft cover 4. It is.

As mentioned above, when people who wear these things compete with motorboats, etc., they are competing for speed from a human psychological standpoint or for profit reasons, and they become overly conscious and attack their fellow boats or the boat and other objects. A person may be thrown over the water due to a collision. At that time, a solid life jacket is worn, so even if the person becomes unconscious, the person will float to the surface of the water.

On the other hand, solid life jackets for racing are designed to prevent injury to the human body from boat propellers, etc., as mentioned above.

It has a built-in solid foam that is thicker than normal and has buoyancy to reduce the impact force caused by collision. For this reason, the human floats almost vertically above the water, but if the person is unconscious due to the weight of the helmet and the natural movement of the human neck, the face will fall in the direction of arrow 6 (Figure 2) and the mouth and nose will be at the surface of the water. It will take the shape of . At this time or before, when the automatic gas filling device is actuated and gas enters the inflatable floating body 7 through the tube 9, the surface fasteners or push buttons attached to the soft cover 4 are inflated. When released by the force, the inflatable floating body 7 inflates and fits in the chin area of a person without constricting the neck, or in the mouth position of the face cover of a helmet. Alternatively, it may fit in the combination of the human chin and the mouth of the face cover of the helmet.

As described above, in this embodiment, a sufficient life-saving effect is exhibited by keeping the mouth and nose, which are the means of human breathing, in the atmosphere.

〔Effect of the invention〕

As described above, according to the present invention, a floating body is inflated by a known gas filling device that automatically operates when immersed in water,
This has the effect of providing a life preserver that saves lives by exhibiting a posture control function that maintains the breathing means of the wearer of the life jacket in the atmosphere.
