Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an evacuation device designed to prevent smoke damage in a fire.

In recent fires in hotels and the like, many people die from inhaling smoke containing highly concentrated toxic gases, especially those generated from new construction materials.

Therefore, cover your neck and upper torso with an impermeable smoke-proof bag or smoke-proof clothing to block outside air, and use the air inside to breathe.
A system has been devised to minimize the damage caused by smoke pollution.

However, as they breathe, the oxygen in the blood becomes insufficient, and the oxygen in the air in the smoke-proof bag and smoke-proof padding becomes diluted, increasing the accumulation of carbon dioxide, making it extremely unsanitary and dangerous. Met.

In addition, devices designed to inhale compressed air are very troublesome to put on, such as carrying the cylinder on one's back. It was heavy and took up space, making it inconvenient to carry, and it was expensive.

The present invention eliminates these drawbacks and allows people to evacuate immediately while freely breathing fresh air in the event of a fire.

Next, the present invention will be specifically explained based on embodiments shown in the drawings.

Example 1 As illustrated in FIG. 1, the base of an intake pipe 3 having an intake port 2 at the tip is attached to an air bag 1 of arbitrary shape made of aluminum foil or high heat-resistant synthetic resin, and the air bag 1 is Inlet port 2
Inflate the air by introducing fresh air into the air inlet, and then open the air intake port 2.
Put a stopper 6 on the bottle and keep it on hand.

In the figure, 20 is a band that fixes the intake port 2 to the mouth.

In the event of a fire, as shown in Fig. 3, quickly remove the stopper 6, hold the tip of the intake pipe 3 in your mouth, and place the air bag 1 in front of your upper body or towards the back as shown by the dotted line in the figure. lower,
The person puts on smoke-proof goggles 13, inhales the air in the air bag 1 through the intake pipe 3 with the mouth, exhales it through the nose, inhales with the mouth and exhales through the nose, and evacuates quickly while breathing in this manner.

When carrying the present invention, the air bag 1 is compressed with both hands to force out the air, the air bag 1 is folded down to make it smaller, and the air bag 1 is carried along with a convenient air pump.

Example 2 The base of an intake pipe 3 having an intake port 2 at its tip is attached to the upper part of an air bag 1 made of aluminum foil, high heat-resistant synthetic resin, or the like.

At the upper and lower ends of the air bag 1, there are devices for stretching the air bag.

There are various ways to do this, but 4' in the figure shows the two sides.

In the figure, 23 is a mounting band.

In the event of a fire, quickly grab the bottom enlarger 4 with one hand, grab the intake pipe 3 with the other hand, and pull the upper and lower enlargers 4.4 to both sides to draw in fresh air. Mouth 2
Inflate the air bag 1 by rapidly sucking air into the air bag 1, and as shown in FIG. glasses 13
Then, the air in the air bag 1 is inhaled through the intake pipe 3 and exhaled through the nose, then inhaled through the mouth and exhaled through the nose.While breathing in this manner, evacuate quickly.

As the air in the air bag 1 is sucked out, the air bag 1 contracts as illustrated by the dotted line in FIG.

In order to quickly inflate the air bag 1, an inlet 5 is provided in the air bag 1.
In some cases, air is sucked into the air bag 1 from the suction port 5 and the suction port 2 at the same time, and the suction port 5 is provided with a plug 6.

The length of time you can breathe at one time in Examples 1 and 2 varies depending on the size of the air bag 1 and the way you breathe, but as a result of experiments, the length of the air bag was 39 cm, the length was 29 cm, and the height was 40
It took 5 to 6 minutes for one centimeter-sized air bag. Therefore, even in the event of a fire in a high-rise building, there is plenty of time to evacuate from the smoke damage.

When staying at a hotel, etc., prepare air bag 1 in advance by sucking a full amount of air.In the event of a fire, you can save time by sucking air into air bag 1, and immediately evacuate from smoke damage. .

When carrying this invention, the air in the air bag 1 is compressed to make it thinner.

The upper enlarger 4' may directly grip and pull the enlarger 4', as shown in FIGS. 6 and 7.

In the embodiment, the air bag 1 is shown to be able to expand and contract in both the horizontal and vertical directions; however, this is not limited to the embodiment;
It can be configured to expand and contract in any direction, such as diagonally.

There are various structures of the air bag 1, but 1 in the figure shows its four sides. Figure 1 is a sphere type, Figure 4 is a lantern type, and Figure 8 is a box type. It is shown in an extended state, and FIG. 6 shows a state in which it is half extended in an accordion style.

In the figure, 7 indicates bones arranged in an appropriate number.

Embodiment 3 An intake port 9 is provided at the base of an appropriately shaped intake pipe 8, and an intake port 2 is provided at the tip thereof.

When a fire breaks out, quickly apply the smoke prevention eye FI13,
Put the intake pipe 8 on your shoulder or hold it in your hand, hold the tip of the intake pipe 8 in your mouth, and lower the intake port 9 to your feet.

Smoke has a low specific gravity, so it rises and flows upwards in the upper spaces of rooms and passageways, without falling to the ground below.

When you breathe in with your mouth, the smoke-free fresh air from your feet is sucked in through the intake pipe 8 from the intake port 9, and you exhale the inhaled air through your nose. Evacuate quickly while breathing.

There are various structures for the intake pipe of this invention, but 8 in the figure shows the two sides, and the hose type in Figs. , Fig. 11 is telescopic, the length can be adjusted, and it can be shortened when carried.

The intake pipe of the present invention is preferably one that does not bend or dent and narrow the airway even when bent. For example, in the case of a hose, a thick one or a corrugated one is better.There are various structures for the suction port, but 9 in the figure shows the two sides, and the suction port 9 is in close contact with the passage surface 21 and closed. Provide isolation material °24 to prevent this.

In the figure, 24 indicates the two sides. In the figure, 10 is a car, 11 is a protrusion, and 12 is a dust strainer such as gauze or filter paper that prevents dust on the passage surface 21 from being sucked in through the suction port 9 when air is taken in.

In the unlikely event that the discovery of a fire is delayed and smoke falls to the passage surface 21, activated carbon or cotton, etc., may be placed in the intake path 16 to prevent the reduced smoke from being sucked in. It is also conceivable to remove the .

In some cases, a rotating device ff114 is provided at a suitable position in the intake pipe of the present invention to facilitate operation.

Example 4 Example 1 above. In step 2-3, the smoke mask 15 is attached to the intake port 2, the intake valve 17 is attached to the intake path 16, and when the breath is exhaled from the flexible edge 22 of the smoke mask 15, the edge 22 opens. An exhaust path 18 is formed, and the edge 22 forms an exhaust valve 19.

The smoke-proof glasses 13 may be formed integrally with the smoke-proof mask 15.

When a fire breaks out, cover your mouth and nose with a smoke mask 15, cover your eyes with smoke glasses 13, and at the same time as you breathe in, the intake valve 17 opens, fresh air is inhaled, and you exhale. At the same time, the intake valve 17 closes and the exhaust valve 19 opens, and the breath is exhaled from the exhaust path 18.
closes, the intake valve 17 opens, and air is sucked in. In this way, you can evacuate while breathing normally.

In the embodiment, the exhaust valve of the present invention is formed by the edge 22 of the smoke mask, but this is not limited to the embodiment, and as illustrated in FIG. An exhaust valve 19' can be installed here to expel air from there.

As described above, the present invention can quickly and safely prevent smoke damage caused by a fire, is hygienic because it allows people to evacuate while breathing fresh air, is convenient to carry because it can be made small, and can be produced inexpensively and in large quantities. It has many effects, such as:

In Embodiment 4 of the present invention, a removable joint 25 may be provided on the intake pipe 3 of Embodiment 1, and air may be introduced into the air bag 1 from there.
