Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a smoke-proof evacuation equipment in case of fire.

2. Description of the Related Art In recent years, the number of casualties due to fires has increased in accommodation facilities such as hotels and inns. This is because smoke containing toxic gas spreads throughout the building in the early stages of a fire, which causes an evacuee to be caught in the smoke and make it difficult to breathe. The delay in initial evacuation due to things such as being overlooked has a large impact.

As a method to prevent the initial damage from smoke in this way, for example, carry a transparent thin bag made of synthetic resin such as polyethylene, inflate the bag and cover it from the head when a fire occurs, and press the mouth of the bag to smoke. It is conceivable to prevent the infiltration of air and to escape while sucking the air in the bag.

However, even if it does so, it is necessary to evacuate only with the air in the bag, which is limited in volume, so that there is a drawback that it cannot withstand long-term use.

In view of such problems, the present invention has been made for the purpose of providing a smoke-proof evacuation tool that can be used safely at least at the time of initial evacuation and can be used for a relatively long time. .

Means for Solving the Problems The present invention is directed to a part of a container or bag body capable of covering at least the head above the neck in a substantially airtight manner, with the container or bag body covered with the head part. A see-through portion for seeing through the outside is provided, and a connecting joint portion for attaching a breathing assistance device such as a portable oxygen cylinder is provided on the container or the bag body.

Action By covering the container body from the head with the breathing aid attached to the connection joint, oxygen lost by breathing continues to be replenished through the above connection joint, resulting in oxygen deficiency for a long time. You can certainly evacuate to a safe place.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.
In FIG. 1, (1) is a smoke-proof evacuation tool (2) of the present invention
The hard container main body which comprises is shown. This hard container body (1) is, for example, an FRP (Fiber Reinforced Plastic).
s) Made of material. In addition, this FIG.
It shows a state in which the hard container body (1) is placed with the ceiling wall (4) closing the upper end portion of the cylindrical side wall (3) facing upward. Further, in the upper and lower intermediate portions of the peripheral side wall (3), horizontally elongated slots (6) forming a viewing window (5) as a see-through portion are formed in a range of about 180 degrees along the circumferential direction. Has been done. On the outer wall surface of the peripheral side wall (3), a transparent plate (7) having a size slightly larger than that of the elongated hole (6) is provided in a smoke-proof state over the entire side edge portion of the elongated hole (6). Is welded to.

On the other hand, at the lower end of the peripheral side wall (3), there is formed an opening edge (3a) which annularly surrounds the opening (8) which opens the entire lower surface of the hard container body (1). (9) is
1 shows a generally rectangular flexible hem piece having at least heat resistance. As the flexible hem piece (9), for example, heat-resistant and fire-resistant cloth or paper is used. In this embodiment, four flexible hem pieces (9) (9) ... Are arranged so that one end side in the longitudinal direction thereof surrounds the entire circumference of the opening (8) and each flexible hem piece (9) (9). One end side of the hem piece (9) is bent in the radial direction so that the opening (8) can be bent.
It projects from the opening edge (3a) around the. Therefore, when the hard container body (1) is lifted with the ceiling wall (4) facing up, the flexible hem pieces (9) (9) ... Are hung downward.

Next, (10) shows a paper string arranged so as to surround the peripheral side wall (3) of the rigid container body (1).
The middle part of (10) is each flexible hem piece (9) (9) ……
It has been attached to the surface side of these flexible hem pieces (9) (9) ... Near the connecting portion between the side wall (3) and the peripheral side wall (3). It should be noted that the both ends of the paper string (10) are adjacent to each other at a position corresponding to the substantially central position of the viewing window (5).
The flexible hem pieces (9) (9) are turned to the longitudinal direction along the opposite side edge portions of the flexible hem pieces (9) (9) and extend to near the tips of the both flexible hem pieces (9) (9). The ends of the paper cord (10) are attached to the surfaces of the flexible hem pieces (9) and (9) by the adhesive tapes (11) and (11).
It is temporarily attached so that it does not fit outside of (9).

In addition, as shown in FIG. 2, the peripheral side wall (3) of the hard container body (1) has a portable oxygen cylinder as a breathing assistance device.
A connection joint portion (13) for mounting the (12) is provided.

Next, a method of using the smoke proof evacuation tool (2) of the present invention will be described. First, the hard container body (1) is lifted. Then, the flexible hem piece (9) connected to the opening edge (3a) of the hard container body (1) hangs downward. At that time, the adhesive tapes (11) and (11) attached to the flexible hem pieces (9) and (9) are peeled off to leave both ends of the paper string (10) in a free state. In this embodiment, both ends of the paper string (10) are temporarily attached by the adhesive tapes (11) and (11), but the parts may be detachably glued.

And, the mouth portion (14) of the portable oxygen cylinder (12),
The portable oxygen cylinder (12) is fixed to the rigid container body (1) by connecting to the connection joint part (13) exposed to the outside. Then, the oxygen emitted from the portable oxygen cylinder (12) will be
It is gradually supplied into the hard container body (1) via (13).

Next, as shown in FIG. 3, the hard container body (1) is covered from the head (15), and then the peripheral side wall (3) is brought into contact with the shoulder opening.
Flexible hem piece (9) hanging downward from the opening edge (3a) of
(9) ...... cover from shoulder to chest. And
Pull both ends of the paper string (10) and gently press the flexible hem pieces (9) (9) against the body to close the shoulder opening,
In that state, the paper string (10) is tied to hold the flexible hem pieces (9) and (9) so as not to loosen. Then, the head (15) is covered with the flexible hem pieces (9) (9) in a substantially airtight manner, so that the air flowing through the inside of the opening edge (3a) is completely removed. It will be blocked sufficiently if not so, so that the inflow of smoke containing particularly toxic gas components with a large specific gravity is blocked in a nearly complete state, and breathing difficulty due to inhaling toxic gas components is prevented. Not only is the smoke hindered, but the smoke does not cause eyesight problems. In addition, the viewing window (5) for external view is attached to the hard container body (1) so that it is located at the height of the eyes (16), (16) with the smoke-proof evacuation equipment (2) attached. Will be provided. Therefore, the external field of view is secured through the viewing window (5), and the escape place is not lost. Further, as in this embodiment, if the viewing window (5) is provided in an angular range of about 180 degrees along the circumferential direction of the peripheral side wall (3) of the hard container body (1), then something will bounce. Even if the rigid container body (1) rotates in the circumferential direction and is displaced due to
(16) If there is an angle range of about 90 degrees to the left and right from the center of (16), a certain degree of field of view is secured, so a sufficient field of view is secured during evacuation and an unexpected situation is avoided.

Then, the oxygen discharged from the portable oxygen cylinder (12) is continuously supplied to the inside of the hard container body (1) through the connection joint part (13), so that the oxygen lost by breathing is long time. Oxygen deficiency does not occur throughout.

The connection joint part (13) has a portable oxygen cylinder (1
Instead of 2), an air purifier equipped with a smoke filter or the like for removing smoke for each toxic gas component may be installed.

When you evacuate to a safe place, tear off the above-mentioned paper cord (10) to separate the flexible hem pieces (9) (9) held by the paper cord (10) from each other. As a result, the hard container body (1) can be easily removed only by pulling it up.

If the smoke-proof evacuation equipment (2) is placed with the ceiling wall (4) facing downward, the opening (8) facing the ceiling wall (4) will be in an upward state, so that it will be used as a dust box. Can also be used. At that time, a disposable synthetic resin middle bag is inserted into the rigid container body (1) as is generally done, and the mouth of the synthetic resin middle bag is folded back to make the rigid container body (1) If it is attached to the peripheral side wall (3), the opening (8) opened upward.
The "trash" thrown in from will be stored in the above-mentioned synthetic resin middle bag. Therefore, the hard container body (1) is emptied by simply pulling out the synthetic resin inner bag for each content, so that not only can it be quickly installed during evacuation, but also the hard container body (1). Since "garbage" does not directly adhere to the inner wall surface of the room, it will be kept in a clean state, and there will be no sanitary inconvenience even if it is directly covered, and it will be installed at hotel and inn accommodation facilities without psychological resistance. There is an advantage that can be done.

In this embodiment, the peripheral side wall (3) of the hard container body (1) has a cylindrical shape, but it is not necessarily limited to a cylindrical shape, and may have a polygonal shape such as a quadrangle or an octagon. It may be. In short, it only needs to be shaped so that the head (15) fits perfectly. Further, in this embodiment, four flexible hem pieces (9) (9) ... Are attached to the opening edge (3a) of the peripheral side wall (3), but instead, pleats are provided in the middle portion. A laterally continuous piece of flexible hem (9) having a groove may be attached to the opening edge (3a) in the same manner so as to be bent in the radial direction.

Further, if the constituent material of the hard container body (1) is transparent or at least translucent, an external view is ensured through the hard container body (1), so that the long holes (6) provided on the peripheral side wall (3) are provided. It is not necessary to force the viewing window (5) to which the transparent plate (7) is attached in a smoke-proof state.

If it is not used as a dust box, a bag body whose hem portion closely adheres to the body may be provided with a connection joint portion (13) for mounting the portable oxygen cylinder (12). Good. If the bag body is transparent or semi-transparent, even in this case, the viewing window (5) to which the transparent plate (7) is attached is not necessary.

As described above, according to the present invention, in the present invention, a connection joint for attaching a breathing assistance device such as a portable oxygen cylinder to a container or a bag body that can cover at least the head above the neck in a substantially airtight manner. By providing the part, if a breathing aid is attached to the connecting joint part, oxygen lost due to respiration will not be supplemented with oxygen, so oxygen shortage will not occur for a long time, and safety will be extremely improved. A remarkable effect is obtained.
