Description

[Detailed Description of the Invention] This invention relates to a lifesaving device, and in particular, to a lifesaving device that can soft-land at a safe location after escaping into the air from a certain location.

When a fire breaks out in a high-rise building, people on floors above the floor where the fire occurred cannot escape to the ground and must rely on ladder trucks to rescue them. Since ladders cannot reach these high places, people on floors above the level reached by ladders have no way of escaping the fire except by waiting for the fire to extinguish, or by escaping to the roof and hoping for rescue by helicopter. Traditionally, in such cases, if initial fire extinguishment fails or rescue by helicopter is delayed,
There were many cases of people suffering from anxiety and jumping from high places, resulting in tragic accidents. Therefore, in order to prevent such disasters, it is necessary to develop a lifesaving device that allows people to safely escape from a fire scene even if rescue by helicopter is impossible.

This idea was created in consideration of the above-mentioned circumstances, and the main purpose of this idea is to ensure that when a fire breaks out in a building, etc., people left on the floors above the floor where the fire occurred are kept safe from the building, etc. The goal is to provide a life preserver that will allow the person to escape. Another object of this invention is to provide a life preserver or aerial evacuation device that allows a person to escape from one dangerous area in the air and move to another safe area.

Embodiments of this invention will be described below with reference to the drawings.

1 and 2 show a lifesaving device as an embodiment of this invention, and FIG. 1 is a longitudinal sectional view of the lifesaving device when it is in use.

In the figure, 1 is a head that expands when filled with gas, and the outer circumference of the head 1 has a collar 2 that protrudes outward when filled with gas. It is provided integrally with the head 1. The head 1 and the collar 2 are made of an airtight and foldable bag-like material. An umbrella part 3 made of a bag-like material is attached to the outer peripheral edge of the collar part 2, and a plurality of control cables 4 are attached to the umbrella part 3, which extend toward the center of the umbrella part 3. head 1
A hollow column 5 extending vertically is attached to the lower end of the center, and the column 5 and the head 1 are configured to communicate with each other. The column part 5 is the head part 1
It is made of the same bag-like material as. A seat 6 made of an airtight bag-like material is attached to the lower end of the column 5 so as to communicate with the space inside the column 5, and a cushion made of urethane foam or the like is attached to the lower surface of the seat 6. 7 is removably attached. The seat part 6 is a part on which the person 8 to be rescued stands, and the pillar part 5 connects the head 1 and the seat part 6, and at the same time is used for the person 8 to hold on to and keep the body stable.

An injection valve 9 configured as a check valve is provided near the lower end of the column 5, and a nozzle such as a gas cylinder is connected to the injection valve 9 to inject a gas lighter than air into the column 5. It is configured as follows.

The space inside the head 1 is divided into two upper and lower chambers 1 by a partition membrane 10.
It is divided into chambers 1 and 12, and the chambers 11 and 12 are
are in communication via a valve 13 provided on the partition membrane 10. The valve 13 has a structure that is reversely interlocked with the exhaust valve 14 provided at the top of the head 1, and the string 1
5 is connected to the movable part of the exhaust valve 14. Therefore, in the normal state when the exhaust valve 14 is closed, the valve 13 is open, but when the exhaust valve 14 is opened, the valve 13 is closed. An operating string 16 of the exhaust valve 14 is suspended in front of the person 8 on the seat 6 along the outer peripheral surface of the head 1.
This operating string 16 is passed through a string ring 17 provided on the outer periphery of the column portion 5. The pillar part 5 further includes:
A rope passing ring 18 for passing the control rope 4 of the umbrella 3 is attached, and the control rope 4 passed through the ring 18 is positioned in front of the person 8.

As shown in FIGS. 1 and 2, the seat portion 6 is provided with a pair of cylindrical pockets 19 (only one of which is shown in FIGS. 1 and 2) parallel to each other. A gas cylinder 20 for propulsion is accommodated in the interior of the gas cylinder 19 . A fumarole pipe 21 is attached to the valve 22 of the gas cylinder 20, and the fume pipe opens at the outer peripheral edge of the seat part 6 through a hole extending from the pocket 19 of the seat part 6 to the outer peripheral edge. An operating string 24 is attached to the valve opening/closing lever 23 of the gas cylinder 20, and the operating string 24 is pulled out from inside the pocket 19 onto the seat 6 and locked at a position where it can be easily operated by a person 8.

Several mooring rings 25 are attached to the seat 6,
A rope (not shown) secured to the mooring ring 25 allows the life preserver according to the present invention to be moored. 2
6 is a safety belt attached to the pillar part 5;
The safety belt 26 restrains the body of the person 8 to the column 5 to prevent it from falling.

Next, how to use the life preserver having the above structure and its state when not in use will be explained.

When not in use, the head 1, column 5, and seat 6 are not filled with gas, so they are all deflated, leaving only the cushion 7 the same size as when in use. However, since the cushion 7 is removable from the lower surface of the seat portion 6, once the cushion 7 is removed, the whole can be folded and stored.

When in use, the cushion 7 is attached to the seat 6 (although it is not necessary to attach the cushion 7), and a rope (not shown) is attached to the mooring ring 25 to moor the life preserver according to the present invention. A gas lighter than air, such as gas, is injected into the head 1 and the seat 6 from an injection valve 9 of the column 5 to inflate both parts. When head 1 is filled with gas,
A collar portion 2 integral with the head portion 1 projects outward. In this case, when there is an updraft at the mooring location, the umbrella part 3 also overhangs as shown by the solid line in the figure, but when there is no updraft, only the collar 2 overhangs. When the head 1 and the seat 6 are filled with gas, it becomes possible to float (it is designed to be able to float even without the overhang of the umbrella 3), so the seat 6
A person 8 to be rescued gets on top, tightens the safety belt 26 and restrains the body to the pillar part 5, and then removes the rope fixed to the mooring ring 25 and floats up. In this case, if necessary, the propulsion gas cylinder 20 can be operated by pulling the operating string 24, and horizontal movement can be achieved using horizontal jets from the gas cylinder. After floating in the air, the umbrella part 3 opens due to the rising air,
Lift increases.

The altitude while drifting in the air is adjusted by pulling the control cable 4 and adjusting the opening degree of the umbrella 3 as shown by the arrows in FIG. Also, the direction in which to descend is also determined by the control line 4.
It can be adjusted to a certain extent by adjusting the amount of tension. However, if you have to move a lot horizontally to escape danger or if you have to make a rapid descent at a certain point, you may not be able to achieve your objective by operating the control line 4 alone. In such a case, operate the operating string 16 to close the exhaust valve 14.
, and exhaust the air from the chamber 11 of the head 1 to rapidly reduce the lift force, or use other operating strings 24
It is possible to perform actions such as horizontal movement by horizontal injection from the gas cylinder 20 by operating the gas cylinder 20.

When the person falls to the ground, the gas in the seat part 6 absorbs the falling shock, and at the same time, due to the cushioning action of the cushion 7, the person 8 can land safely without any impact.

As described above, this invention provides a new lifesaving device that can safely evacuate people on floors that cannot be reached by ladders in the event of a building fire or the like.

FIG. 3 shows an embodiment in which safety is further improved by increasing the sense of stability of the person riding the life preserver. The seat 6A of this embodiment has a smaller diameter than the seat 6 of the embodiment of FIG. Accordingly, when the person 8 sits on the chair, his/her legs below the knees hang down, so the sense of stability is increased compared to the embodiment shown in FIG. 1, and at the same time, psychological anxiety can be reduced. Furthermore, since the seat 6A of this embodiment is designed so that its height h is greater than the length of the shin of the person 8, the toes of the feet do not land earlier than the seat 6A when the person lands. Therefore, a soft landing can be made without applying impact to the toes. Furthermore, since the seat 6A of this embodiment is provided with a recess 6a on its bottom surface, the outer periphery of the seat 6A deforms to expand outward at the landing point, allowing the user to land without falling. be able to.

The embodiments of the present invention shown above are merely illustrative, and the present invention is not to be construed as being limited to these embodiments. It should be noted that transformations and modifications are possible.

The features of the embodiment of this invention are listed below.

(i) Because the buoyancy is mainly obtained from the gas inside the head, the descent speed is low, and the general public can use it without fear.

(ii) Since a pillar is provided for grasping, the feeling of fear while floating in the air can be reduced.

(iii) Because it has a soft seat, there is almost no shock when landing, and it does not sink even if it falls onto water.

(iv) When the head is filled with gas, the column and seat are also filled with gas at the same time, so that the device can be brought into a usable state reliably and quickly with a simple operation.

Since the head, pillar, and seat are integrally constructed of a foldable cloth-like airtight member, it is easy to store and store when not in use.
