Description

[Detailed description of the invention] (Technical field) The present invention relates to a life-saving waterproof mask used in the event of a marine accident, etc.

(Prior art) Lifesaving equipment such as immersion suits (or survival suits) and life jackets used in the event of a marine accident are usually made so that only the face is above the sea surface, so they cannot be used at sea. In many cases, while waiting for rescue, victims' faces would be submerged by large waves, resulting in difficulty breathing and death or rapid fatigue.

Therefore, in order to prevent such a situation, while waiting for rescue at sea, you can avoid being affected by the waves.
A life-saving waterproof mask that allows people to breathe safely has been proposed.

Figure 1 shows an example of the waterproof mask. 1 is a floating body with a weight 1a at the bottom, 2 is a floating body that rises upward from the floating body when it is floating on the water surface, and has an air intake port at the tip. a ventilation pipe; 3 is a cover for preventing water droplets from entering the intake port; 4 is a facepiece; an exhaust valve for discharging exhaled air to the outside;
It is equipped with a drain valve to drain out any water that has entered. 5 is a flexible connecting pipe that connects the face piece 4 and the ventilation pipe 2. Note that a water draining device may be provided in the section A in FIG. The illustration does not show the immersion suit or life jacket.

A waterproof mask constructed in this way allows the person to breathe safely while waiting for rescue at sea.

By the way, when it comes to maritime accidents, there are cases where there is a relatively large amount of time for evacuation, such as a sinking of a ship due to flooding, and where the person knows about the accident and puts on a life preserver.
There may be unexpected accidents such as falling from a ship into the sea during fishing or other onboard work, or emergencies such as a ship suddenly capsizing. In the former case, there is no problem even if the waterproof mask is quite large, but in the latter case, the waterproof mask is required to be small and portable.

On the other hand, the inlet of a waterproof mask needs to be located at an appropriate height above the sea level to prevent seawater from entering through the inlet.

(Problems to be solved by the invention) The present invention was made in view of these demands.It is small and portable when not in use, easy to wear and operate when in use, and can be carried while waiting for rescue at sea. The purpose is to provide a life-saving waterproof mask that allows people to breathe safely without being affected by waves.

(Means for solving the problem) In order to achieve this purpose, the life-saving waterproof mask of the present invention is constructed in such a way that a plurality of pipes with different diameters are connected in multiple stages so that small-diameter pipes can be sequentially stored inside a large-diameter pipe. A telescopic ventilation pipe, one end of the maximum diameter pipe of the ventilation pipe is used as an intake port, a cover that covers the intake port to prevent water droplets from entering, and a cover that covers the intake port to prevent water droplets from entering, One end is a drain port, a drain valve is provided at the drain port, a telescopic flexible connecting pipe has one end connected to the end of a branch pipe branched from the middle part of the largest diameter pipe, and this connecting pipe It is connected to the other end and consists of a facepiece equipped with an exhaust valve that covers at least the person's mouth and nose, and a joint that rotatably connects the smallest diameter pipe to a waist belt or the like.

(Function) The life-saving waterproof mask with the above configuration should be carried with the ventilation tube shortened and hung on a waist belt, etc., and should it be thrown out at sea due to an unexpected accident, etc.
Stand the ventilation pipe upward and extend it, and also extend the flexible connecting pipe and attach the face piece. Therefore, the intake port located at the tip of the ventilation pipe is located above the sea level, and the intake port is covered with a cover to prevent seawater from entering as much as possible. When the water gets too high, the drain valve at the other end of the ventilation pipe opens and drains water, so water does not get into the flexible connecting pipe or the facepiece, allowing you to breathe safely.

Hereinafter, embodiments will be described in detail with reference to the drawings.

(Example) Figure 2 shows an example of the present invention.
Shows the state in use. Reference numeral 6 denotes a multi-stage expandable ventilation pipe, which is constructed by connecting a plurality of pipes with different diameters in multiple stages so that small-diameter pipes can be sequentially accommodated in a large-diameter pipe. One end of the maximum diameter pipe of the ventilation pipe 6 serves as an intake port, and a branch pipe 6a is provided in the middle of the pipe.
7 is a cover that covers the intake port to prevent the intrusion of water splashes, etc. 8 is a drain valve with a cover provided at the drain port with one end of the minimum diameter pipe of the ventilation pipe 6 as a drain port; 9 is a drain valve thereof. A telescopic flexible connecting pipe whose one end is connected to the end of the branch pipe 6a, 10 is a facepiece connected to the other end of the flexible connecting pipe 9,
It covers at least the mouth and nose and is equipped with an exhaust valve.

FIG. 3 shows the state of this embodiment when not in use. When not in use, the ventilation pipe 6 is shortened and lowered to the belt 11 around the waist. The waist belt 11 and the ventilation pipe 6 are the fourth
As shown in the figure, they are connected via a rotatable joint 12 attached to the pipe with the smallest diameter. Also, at this time, the facepiece 10 is also stored in the storage case 13.
The flexible connecting pipe 9 is placed in a contracted state.

This embodiment configured in this way can be carried in a reduced state by being hung on a waist belt or the like during normal times, and when used in an emergency, the facepiece 10 is taken out from the case 13 and worn, and the ventilation pipe is 6 upright, extend it, and hold it as shown in Figure 2. In this state, the air intake is located above the sea level, allowing air to be taken in.

A cover 7 is provided on the intake port to prevent water from entering as much as possible, but even if water does enter, it will flow downward through the vent pipe 6 and the water level inside the vent pipe 6 will rise to the level outside. When the water becomes higher than the sea level, the water pressure opens the drain valve 8 and some of the water is discharged. Therefore, the water level in the ventilation pipe 6 will never rise above sea level, and water will not enter the flexible connecting pipe 9 through the branch pipe 6a.

(Effects of the invention) As explained above, according to the invention, it is possible to provide a life-saving waterproof mask that is compact and portable during normal times and is extremely easy to operate when worn in an emergency. It allows people to breathe safely while waiting for rescue at sea in the event of a marine accident, etc., and is extremely effective in saving precious lives.
