Abstract

PURPOSE:To allow a refugee to escape easily in an emergency by a method wherein a central chamber is formed in the center of a balloon filled with oxygen or helium, a makeup oxygen or helium cylinder is provided in the center of the central chamber, an entrance and an air vent leading to the central chamber are located opposite each other on a plane which perpendicularly intersects to the cylinder. CONSTITUTION:A gas feed nozzle 7 is located on the circumference of a balloon 1 or near an air vent 5 of an air ventilation duct 6 leading from the air vent 5 to a central chamber 3. An entrance/exit 4 that leads to the central chamber 3 is located on one side of a plane which perpendicularly intersects to a gas cylinder 2 in the central chamber 3. The balloon 1 provided with the cylinder 2 is usually evacuated, and filled with oxygen or helium in an emergency. Then, a refugee enters the central chamber 3 from the entrance/exit 4 provided on the one side, and embraces the cylinder 2 when escaping. As the central chamber 3 is provided with the cylinder 2 in its center, the shock of falling down can be lessened by embracing the cylinder 2 after the refugee enters the central chamber 3. The air vent 5 is located opposite to the entrance and connected to the central chamber 3, so that a good ventilation is maintained when the refugee enters the central chamber 3.

Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is used for emergency escape when escape from a normal entrance is impossible due to a fire in a high-rise residence such as a building or condominium, or due to building destruction such as an earthquake. This relates to an emergency escape ball for use in emergency situations or for escaping from aircraft.

(Conventional technology) Mechanical evacuation evacuation devices are often used when escaping from buildings or condominiums in the event of a fire, etc., which not only increases the cost of setting up, but also often impairs the appearance of the exterior. Because of this, there are many accidents where the drums get rusty or don't work properly.

Furthermore, there were no escape devices for escaping from the aircraft.

(Problems to be Solved by the Invention) The present invention is an emergency escape ball for safely and fearlessly escaping from buildings, high-rise residences such as condominiums, aircraft, etc. without relying on mechanical means. It can be stored in buildings, condominiums, airplanes, etc. without taking up much space, and allows evacuees to easily enter the central room and escape in the event of an emergency.

(Means for Solving the Problems) The present invention provides a central chamber 3 in which a supplementary oxygen or helium cylinder 2 is installed in the center of a bag 1 filled with oxygen or helium, and This emergency escape ball is provided with an entrance/exit 4 connected to the central chamber 3 at one end so as to be perpendicular to the cylinder 2 of No. 3, and an air hole 5 connected to the central chamber 3 at the other end.

(Function) Is the present invention Pino? An emergency escape ball that can be used for emergency escape when it is impossible to escape from a normal entrance due to a fire in a high-rise building such as a high-rise building or an earthquake or other building destruction, or for escaping from an aircraft. Therefore, in case of an emergency, the bag 1 is filled with oxygen or helium, and the evacuee enters the central room 3 through the entrance 4 provided at one end of the bag 1 and escapes by holding the cylinder 2. This is what we aim to do.

The size of the bag 1 changes depending on the gas to be filled, and when injecting oxygen, the bag has a diameter of about 3 m, and in the case of helium, it has a diameter of about 5 to 8 m.

Not only is the diameter of the central chamber 3 approximately 70 cm, but the cylinder 2 is attached to the center, so evacuees can enter the central chamber 3 and hold the cylinder, thereby softening the shock when they fall. It is something that can be done.

The air hole 5 at the other end connected to the central room 3 can improve ventilation when an evacuee enters the central room 3.

Normally, the bag body 1 with the cylinder 2 attached is deaerated, and when necessary, it is inflated and used for escape. It is advisable to arrange the lower air intake near the air hole 5 of the ventilation hole 6.

The reason for providing an entrance and exit connected to the central room 3 at one end so as to be orthogonal to the cylinder 2 in the central room 3 is to make it easier for evacuees to grab onto the cylinder 2 when they enter the central room 3.

After the evacuee enters the room, the cylinder installed in the central room 3 is adjusted while calculating the floating dust in the bag, and the valve of the cylinder 2 is opened and closed to supply air.

In the central chamber 3 where evacuees are carried, depending on the weight of the evacuees, they may fall suddenly or float due to the levitation blade of gas such as helium that has been injected in advance, so adjust it by opening and closing the valve of cylinder 2. It is something.

Experiments have shown that if the diameter of the bag is increased to 8 m, it will float even when carrying a 70 kg person.

In addition, the bag has a double structure, making it difficult to break even when filled with gas such as helium, and preventing the gas from escaping even if the outer shell is damaged due to impact or location when dropped. It is.

It is preferable to use a new material such as aromatic polyacid as the material for the bag body.

Moreover, the reason why the bag body 1 is made spherical is that it is possible to soften the impact as much as possible when the evacuee descends to the descent point.

The reason why the evacuee is holding the cylinder 2 in the central room 3 is not only to fix the evacuee, but also because by manipulating the cylinder 2, the spherical body is distorted so that the falling direction can be changed arbitrarily.

It goes without saying that the bag 1 is preferably transparent in order to arbitrarily control the drop point as a result of such an operation.

The injection gas is mainly helium because the weight (%) of oxygen is 23.2 and that of helium is 0.00 [107].

Hydrogen is L (lot), but it is dangerous and is not used.

(Effects of the present invention) The present invention is useful for emergency escape when it is impossible to escape from a normal entrance due to a fire in a high-rise residence such as a building or condominium or building destruction due to an earthquake, or when escaping from an aircraft etc. Not only can the bag be escaped with a simple operation, but the bag can be degassed and stored, giving rise to the advantage that no storage space is required.

Also, since the structure allows evacuees to manipulate the sphere to fall to any desired location, it goes without saying that it can be used not only for emergency evacuation but also for aerial leisure.
