[0009]

Embodiment 1 of the present invention comprises a parachute portion 10, a main body portion 20 and an inflator 30. The parachute part 10 has a hanging string connected to an umbrella-shaped parachute body 11 and suspends the body of an escaped person like a conventional parachute, but the parachute of the present invention is part of the umbrella-shaped parachute body 11. It is characterized by forming an air tube 12 for opening a closed umbrella.

That is, the air tube 12 is a tubular tube body for passing air disposed in a part of the parachute, and it communicates with an inflator incorporated in a backpack which an escaped person carries on his back, which will be described later. When the tube body is filled with air by the air supplied from the inflator through the tube 13, the umbrella-shaped parachute body 11 in the closed state is forcibly opened and expanded by the expansion output. The formation position of the air tube 12 is not limited as long as it opens and closes the umbrella, but as shown in FIG. 1, if a tube-shaped tube is formed at the end of the umbrella-type hem, the expansion and expansion of the ring will expand and expand the umbrella. Be certain.

Next, the main body portion 20 will be described. The main body portion 20 refers to a bag body having a cushioning property by incorporating an air chamber 22 therein to protect an escaped person. The first mode is as follows. As shown in FIG. 2, an air chamber 22 is built inside to form a spherical bag body 21 having cushioning properties. Inside the spherical bag body 21, when it expands, a storage chamber 24 having a volume that the entire body can comfortably fit inside the knee bag of the escaper is formed. That is, the spherical bag body 21 has the aim of covering the whole body of the escaped person with the cushioning air chamber 22 and protecting the fallen escaped person. In order to ensure that the cushioning property is maintained, the air chamber 22
It is desirable that a compartment 23 be provided inside the device to avoid a bias of the air pressure at the time of collision, and a pressure adjusting valve be attached.

A window 25 is formed above the accommodating chamber 24 so that the escape person can slip in, and as shown in FIG. 2, the escape person can enter the spherical bag 21 folded from the window 25. After the gas is injected into the air chamber 22 described later, the bag body is inflated to form a storage chamber 24 that surrounds and surrounds the body.

That is, the spherical bag 21 is normally in the state shown in FIG.
When the gas is injected therein, the spherical bag body 21 is inflated so that the lantern is just extended by the inflating output of the gas, and the accommodation chamber 24 is formed therein.

The sphere 21 is connected via a connecting pipe 26 to an inflator 30 which generates gas for expanding the sphere contained in the backpack 27. As shown in FIG. 6, an example of the inflator is provided with an igniting agent 31 and a gas generating agent 32, a small amount of explosive is ignited by an electric signal, and a propellant is ignited by the heat of combustion thereof to remove sodium azide. It has the function of sending nitrogen gas generated when the propellant, which is the main component, undergoes a decomposition reaction to the bag.

That is, when the gas generated in the inflator 30 is injected through the connecting pipe 26, the folded spherical bag 21 is forcibly expanded by the expansion force, and the spherical bag 21 is swiftly expanded there.
The air chamber 22 having a cushioning property is surely formed.

Another embodiment 2 will be described. As shown in FIG. 4, the parachute portion 10, the main body portion 40, and the inflator 30 are included.
0 and the inflator 30 are the same.

The body portion 40 is provided with body portions 41a and 41b which come into contact with the chest and the back portion in the front and rear, and the rod-shaped bag body side portion 4 extending from the body portions 41a and 41b at right angles to the side portions of the body of the escaped person.
2a and 42b are arranged, and rod-shaped bag body height portions 43a and 43b extending parallel to the vertical direction of the body are formed on the rod-shaped bag bodies 41 and 41. The rod-shaped bag bodies 41, 41 are formed into a rod-shaped bag body having a cushioning property by incorporating an air chamber therein, that is, the rod-shaped bag body side portions 42a, 42b are
The side surface of the escaper is covered with a cushioning air chamber, and the rod-shaped bag body height portions 43a and 43b cover the escaper's height direction and try to protect the side and height of the falling escapee.
A compartment similar to that of the first embodiment is provided inside the air chamber,
It is desirable to avoid bias in air pressure in the event of a collision.

Explaining the third embodiment further, as shown in FIG. 5, in addition to the parachute portion 10 and the inflator 30, there is a main body portion 50, and the main body portion 50 has an air chamber inside to provide cushioning properties. The provided hemispherical bag 51 is formed.
Inside the hemispherical bag body 51, when it is inflated, a storage chamber 52 having a volume capable of containing the lower body of the escaper is formed therein. That is, the hemispherical bag body 51 covers the lower body of the escaper with a cushioning air chamber in order to protect the escaper who falls, and a compartment is provided inside the air chamber to prevent uneven air pressure during a collision. It is desirable to avoid

Next, the operation of this embodiment will be described. The device of the present invention is usually provided in a compact state in a folded state in a part of an office or the like of a building on a higher floor, and is provided with one device for one person in principle. As for the place, even if several people are put together in one place,
Each person may place it near their desk.

When an emergency evacuation situation such as a fire occurs, it is assumed that evacuation will be difficult for people in the upper floors and people whose evacuation routes are closed. In this case, the device of the present invention is taken out, and first, the spherical bag body 21 is expanded toward the window and the backpack 27 is carried on the back. Then, with the backpack 27 on the back, the window 2
From 5, it goes into the accommodation chamber 24 of the spherical bag body 21, and at that time, it is suitable for the foot to step on the bottom of the spherical bag body 21. Then, from the windows of the building, etc., we head downstairs, jumping down in a fashionable manner holding the device.

In the process of falling, the inflator 30
Press the ignition button. Then, as described above, the ignition agent 31
The propellant is ignited by its combustion heat, and the propellant containing sodium azide as a main component undergoes a decomposition reaction to instantly generate nitrogen gas.

When this gas is first sent to the air tube 12 of the parachute portion 10, the gas accompanied by pressure causes the air tube 12 to swell, and the umbrella-shaped parachute portion in a folded state due to the expansion of the air tube 12. Forcibly expand 10. In particular, when the air tube 12 is formed in a ring shape at the hem of the parachute body 11, the bulging of the air tube 12 works in the direction of expanding the ring due to the characteristic of the ring, and even a slight gas body can surely form an umbrella shape. It works to expand the parachute body 11. As a result, when the parachute unit 10 is opened, the speed of the fall is suppressed by any deceleration effect due to the air resistance even if the parachute unit 10 jumps down from any higher floor.

At the same time, most of the generated gas is
Since it is sent to the air chamber 22 of the spherical bag 21 through the connecting pipe 26, when the air chamber 22 is filled with gas, the folded spherical bag 21 expands, and the spherical bag 21 expands like a lantern. Inflate to 21. When the accommodation chamber 24 is formed inside, the knees are folded and the escaper is completely covered. That is, the escaped person is placed in a storage chamber 24 surrounded by the air chamber 22 having a rich cushioning property, and falls in the air in that state.

Thus, the landing on the ground is approached, and the falling speed is extremely moderately suppressed by the decelerating effect of the parachute portion 10, and the vehicle finally collides with the ground. At this time, some impact is unavoidable, but the air chamber 22 rich in cushioning absorbs this impact, effectively protects the escaped person inside, and realizes safe evacuation. At this time, if it is in the valley of the building, there is a fear of contact with an adjacent building or the like, but the storage chamber 24 whose whole body is covered by the spherical bag body 21 is safely protected. Further, if the compartment 23 is provided in the air chamber 22, the compartment 23 supports the concentration of the collision pressure that occurs at the ground contact portion during the collision, and the collision pressure is relieved.

In the use of the second embodiment, during an emergency evacuation, the device of the present invention is taken out, the backpack is carried on the back, the building window or the like is directed downstairs, and the device is carried in a suitable manner. The pushing of the ignition button of the inflator 30 is the same as in the first embodiment. Then, the gas generated in the inflator 30 is transferred to the body portions 41a, 4a.
When it is sent to 1b, the folded body parts 41a, 41b swell, and then the rod-shaped bag body side portions 42a, 42b swell in the orthogonal direction, extending to the side surface of the body of the escaped person, while the rod-shaped bag body height portions 43a, 43b. Bulges vertically and extends along the height of the escapee's body.

When falling in the air in that state, for example, even if a part of an adjoining building may be contacted on the way, the chest and back are protected and the side and bottom are protected. As it is, it will not hurt. When it finally falls to the ground, the parachute portion decelerates, and the impact is moderated by the rod-shaped body extending in the height direction and having a high cushioning property, so that the rod is safely protected. At this time, the bag body is simple to manufacture and easy to wear on the body.

In the use of the third embodiment, taking out the device of the present invention, carrying the backpack, and jumping down from the window of the building or the like toward the downstairs is the same as in the above-mentioned first embodiment. When the gas generated in the inflator 30 is sent to the air chamber of the hemispherical bag 51, the gas is filled in the air chamber, and the folded hemispherical bag 51 expands into a hemispherical shape to cover the lower body of the escaped person. .

When falling in the air in that state, for example, even if a part of an adjacent building is contacted on the way, it is protected by the side surface of the hemispherical bag 51, and finally the ground surface. When falling, the impact is surely relieved by the lower cushioned hemispherical bag 51, which is of course decelerated by the parachute portion. Also, if it falls to the surface of the sea, it will play the role of a lifeboat.

[0029]

The present invention is based on the above-mentioned structure and operation.
It has the following excellent effects.

A parachute portion that is forcibly and surely expanded by an inflator capable of instantaneously generating gas significantly slows down the falling speed, and at the same time, landing is achieved by the cushion effect of the bag body that is forcibly inflated by the inflator. The impact of the time will be alleviated, and it will play an epoch-making role that enables escape from high places such as skyscrapers and airplanes, which were previously considered difficult.

At this time, even an inexperienced amateur or the like can operate the inflator with a single button operation, after which the parachute portion is automatically opened and expanded and the bag body is inflated, resulting in an accident due to an operation error. It also eliminates the fear of fear.

Further, since it can be folded and stored compactly when it is not used, it is an invention of excellent effectiveness such as being able to be stored even in a familiar place in a building or on an airplane.
