2. Description of the Related Art In firefighting activities such as a building fire, a firefighter carries an air breathing apparatus to enter a fire site deep in a building with a low oxygen concentration or a building where toxic gas is generated, and to extinguish the fire. I do work. At a fire site such as a building fire, a power outage is generally occurring, so that firefighters are forced to perform fire fighting activities in dim darkness.

Usually, a plurality of firefighters perform the above-described fire fighting activities, and unless each firefighter checks the position of or distinguishes another firefighter from each other, an injury or accident may occur. In addition, firefighters should be checked to see if firefighters are left behind in dangerous places where building collapse is expected, or to conduct organized firefighting activities taking into account the amount of oxygen remaining. It is necessary to always keep track of the position and the affiliation group.

[0004] However, hitherto, the location and identification of a firefighter in a dark place have relied solely on the experience and feeling of the firefighter, which has the problem of adversely affecting the efficiency of firefighting activities.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a pneumatic respiratory cylinder and its covering material, which enable a firefighter to easily confirm and identify a position even in a dark place.

It is another object of the present invention to provide an air breathing apparatus cylinder and a covering material for the firefighter, which can ensure the position confirmation function without increasing the cost of repainting the pressure vessel.

[0007]

In order to achieve the above-mentioned object, an air breathing apparatus according to the present invention comprises a pressure-resistant container capable of being filled with compressed air and having at least a part of a coating material having a luminous property attached and detached. It is characterized by being freely mounted.

[0008] Further, the coating material of the air respirator cylinder of the present invention is a coating material having a luminous property, characterized in that it can be mounted on the outer surface of a pressure-resistant container constituting the air respirator cylinder. It is.

[0009] The present applicant has filed Japanese Patent Application No. 11-7 filed earlier.
In 220, by attaching a luminous paint to at least a part of the pressure-resistant container of the air respirator cylinder, the position of the firefighter can be easily confirmed and identified by the luminous action of the luminous paint even in a dim fire scene. Suggested.

[0010] However, it is obliged to conduct quality inspections of the air respirator cylinders at predetermined intervals.
In particular, in the case of a fiber-reinforced resin cylinder, even if a part of the protective coating applied to the entire outer surface of the pressure-resistant container is peeled off, the inspection is rejected. Therefore, it is necessary to repaint before the inspection. However, if the above-mentioned phosphorescent paint is repainted in this repainting operation, the phosphorescent paint itself is very expensive, so that a considerable cost burden cannot be avoided.

According to the present invention, the coating material having a luminous property is given to the coating material independent of the pressure-resistant container, and the coating material having the luminous property can be detachably attached to the pressure-resistant container, so that the coating material having the luminous property in a dim fire scene is provided. The position of the firefighter can be easily confirmed and identified by the light emitting action of the material, and only the protective paint needs to be applied at the time of repainting, so that the expensive phosphorescent paint can be omitted. In addition, by appropriately selecting the material (soft resin, synthetic rubber, and the like) and shape of the coating material, the coating material can function as a protective material for the pressure-resistant container. It is possible.

In the present invention, the luminous property of the coating material is obtained based on the luminous substance mixed or applied to the coating material. The phosphorescent substance may be any substance that emits phosphorescence or fluorescence in a dark place after being exposed to light, and specifically includes a phosphor and a substance that causes various luminescence phenomena in addition to a phosphor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be specifically described below with reference to the accompanying drawings. FIG. 1 shows an air respirator cylinder according to an embodiment of the present invention, and FIGS. 2 and 3 illustrate an air respirator provided with the cylinder. In the drawing, a cylinder 1 includes a cylindrical pressure-resistant container 1a capable of being filled with compressed air and a valve 1b. The structures and materials of the pressure-resistant container 1a and the valve 1b are not particularly limited. For example, the pressure-resistant container 1a can be configured to have a laminated structure of a liner layer made of a metal such as aluminum and a fiber-reinforced resin layer using glass fiber, aramid fiber, carbon fiber, or the like as a reinforcing fiber. A coating layer of a coating film is formed on the outer surface of the pressure vessel 1a.

A cap-shaped covering material 2 having a luminous property is detachably attached to the bottom of the pressure-resistant container 1a. The coating material 2 is formed of a soft resin or a synthetic rubber mixed with a luminous substance. In addition, when providing a protective action to the pressure-resistant container 1a, the thickness of the coating material 2 is set to 0.3 to 1
It is preferably set to 0.0 mm.

The phosphorescent substance is not particularly limited, but sulfides such as zinc and calcium to which a trace amount of a heavy metal activator is added can be used. For example, zinc sulfide-based [nZnS. (1-n) CdS: Cu] (n =
0.78-1.0, Cu = 0.01%), calcium sulfide type [nC
aS. (1-n) SrS: Bi, Cu] (n = 0 to 1.
0, Bi = 0.04%, Cu = 0.01%). Generally, this further includes tritium ( ³ H), ¹⁴⁷ Pm,
^A very small amount of a radionuclide such as ²²⁶ Ra is added. As a more preferable phosphorescent substance, a solvent type [SrAl ₂
O ₄ : Eu, Dy] or water-based [Sr ₄ Al
₁₄ O ₂₅ : Eu, Dy]. These luminous substances have excellent luminous properties and do not require the addition of radioactive substances.

The covering member 2 is provided with a light reflection layer 2a. The light reflecting layer 2 a reflects light from the outside and supplements the light emitting action of the coating material 2. The light reflection layer 2 a may be embedded inside the coating material 2 or may be attached to the surface of the coating material 2.

As shown in FIGS. 2 and 3, the cylinder 1 is mounted on the back plate 3 so that the valve 1b is on the lower side, and the band 4 is wrapped around the pressure-resistant container 1a. Fixed. This back plate 3

One end of an air supply hose 8 is connected to the valve 1b of the cylinder 1, and a respiratory mask 9 is attached to the other end of the air supply hose 8. The respirator 9 is for supplying air to a firefighter through the air supply hose 8. Therefore, it is preferable to arrange the air supply hose 8 along the back plate 3 so as to prevent damage during fire extinguishing activities. A pressure gauge 10 branches off from the air supply hose 8.
Thereby, the internal pressure of the cylinder 1 can be confirmed.

When a fire extinguishing operation is performed using the above-described air respirator, the luminous covering material 2 mounted on the outer surface of the pressure-resistant container 1a is exposed to light to be in an excited state prior to the fire extinguishing operation. . By keeping the covering material 2 in the excited state in this way, even in a dimly lit fire scene, the position confirmation and identification of the firefighter can be easily performed by the light emitting action of the luminous substance.

On the other hand, in long-term use, the pressure-resistant container 1a
If a part of the coating is peeled off, the coating material 2 may be re-coated with the coating material 2 removed, and the coating material 2 may be mounted again after the coating. The coating work of the pressure-resistant container 1a can be easily performed by making the coating material 2 detachable in this manner.

In the above-mentioned cylinder for an air breathing apparatus, the bottom of the pressure-resistant container 1a comes into contact with a road surface or an obstacle at the time of handling, so that this portion is easily damaged, but the covering material 2 is preferably made of a soft resin or synthetic rubber. By forming the cap material from a material having excellent cushioning properties into a cap and covering the cap with the bottom of the pressure-resistant container 1a, the coating material 2 can function effectively as a protective material and prevent the surface coating of the pressure-resistant container 1a from peeling off. Can be.

In the present invention, the shape of the coating material is not particularly limited, and can be variously formed as required. For example, as shown in FIG. 4A, the shape of the coating material 2 may be a cap having an opening 20 through which the valve 1b is inserted, or as shown in FIG.
Of the pressure-resistant container 1a as shown in FIG. 4 (c). As a method of attaching these coating materials to the pressure-resistant container, the coating material is bonded to the pressure-resistant container with an adhesive, or in the case of a cap or a ring, fitted to the pressure-resistant container based on the elastic force of the coating material. You may do it.

In the above embodiment, the case where the coating material is molded from a soft resin or a synthetic rubber mixed with a luminous substance has been described. However, in the present invention, a luminous paint containing the luminous substance is applied to the surface of the coating material. You may do it.
In this case, it is possible to form symbols, characters, shapes, colors, and the like indicating various kinds of identification information based on the phosphorescent paint. More specifically, a sign indicating a fire station or a municipal mark or a character indicating a group to which a firefighter belongs is formed from luminous paint, or the shape or color of the luminous paint is variously changed for each group to which firefighters belong. You may do it. By giving the identification information to the covering material, a firefighter and his / her team can be easily specified in a fire fighting activity.
