BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster helmet worn during fire fighting and rescue activities.

[0002]

2. Description of the Related Art At a fire site, carbon monoxide and other toxic gases are generated, which hinders fire extinguishing and rescue activities, prematurely extinguishes fires and saves lives. SUMMARY OF THE INVENTION In order to solve the above problems, the present invention discloses a helmet that can breathe by shutting off outside air.

[0003]

[Means for Solving the Problems] The helmet of the present invention has a head
Inside the helmet (1) covering from (7) to the neck (8), a small oxygen cylinder (5) and a breathing mouthpiece (5) connected to the cylinder (5) are provided, and the lower end of the helmet (1) is inserted. Opening (1
An endless tube (6) is attached over the entire circumference of (3), and an air filling port (61) is provided in the tube (6).

[0004]

[Action and effect] Wearing a helmet (1), mouthpiece
Hold (5). The tube (6) is filled with air and inflated, and the space between the insertion opening (13) of the helmet (1) and the neck (6) is closed by the inflated tube (6) to block the inside and outside of the helmet. .

With this, it is possible to prevent the invasion of outside air into the helmet, that is, the invasion of carbon monoxide and other toxic gases generated by a fire, and to get as close as possible to the fire site to effectively discharge water. It is also possible to invade a fire scene and carry out rescue operations.

EXAMPLE A helmet (1) is a full-face type that covers from the head (6) to the neck (7), and is made of a material having high strength and excellent heat resistance as a whole. A cushion material (2) is attached to the.

The front surface of the helmet has a large opening (14) corresponding to the position of the eye, a sealing material (15) is attached to the opening (14), and a shutter type transparent closing plate (3) Is airtightly closed.

A closing plate storage space (11) is provided in the wall above the front opening (14), and the closing plate (3) is lifted to raise the space (11).
Can be stored in. A balloon (31) is provided on the upper part of the space (11), and by inflating the balloon (31), the closing plate (3) can be pushed out of the space (11) to close the opening (14).

Above the front opening (14), a collar facing forward.
(12) is projected. Inside the lower part of the front opening (14),
Breathing mouthpiece (5) is deployed, helmet (1)
A small acid cylinder (5) is detachably attached to the inner surface of the rear part, and the cylinder (5) and the mouthpiece (5) are connected via a pipe (51).

[0010] The trout piece (5) has the same structure as a known inhalation mouthpiece used for scuba diving, and when it is sucked and sucked, oxygen in the cylinder (5) can be sucked, and when it is exhaled, a helmet ( 1) Exhausted inside.

An endless tube (6) is provided on the inner surface of the lower end opening (13) of the helmet (1) over the entire circumference, and the tube (6) is provided with an air filling port (61). Has been. Tube (6) and balloon (31) for closing the closing plate
Is connected to a conduit (9) arranged within the thickness of the helmet (1).

The pipe line (9) is, as shown in FIG. 3, a cylinder (5).
To the balloon (31) from the first passage (91), and the balloon (31)
To the tube (6) and the second passage (92).
The first passage (91) is provided with an opening / closing valve (90) which can be operated from the outside of the helmet (1), and the tube (6) is provided with a discharge pipe (94) having a discharge valve (93). It is provided outside of.

Then, the helmet (1) is put on and the mouthpiece (5) is held. The on-off valve (90) is opened to inflate the balloon (3) and the tube (6), thereby closing the closing plate (3) and inserting the helmet (1) into the insertion opening (13) and neck.
The space between (8) and (8) is closed by a bulging tube (6) to block the inside and outside of the helmet.

As a result, invasion of outside air into the helmet, that is, invasion of carbon monoxide and other toxic gases generated by a fire can be prevented, so that it is possible to approach a fire site and effectively discharge water. In addition, it is possible to perform rescue activities by invading the fire site.

Exhaust gas fills the inside of the helmet, and the pressure inside the helmet is slightly higher than the outside, so the front opening (14)
And the closing plate (3) or the rubber tube (6) and neck (8)
Even if there is a slight gap between and, it is possible to prevent outside air from entering the helmet. Open the exhaust valve (93) to open the balloon (3
The air in 1) and the tube (6) can be evacuated to manually open the closing plate (3), and the helmet can be taken off. It is also possible that the closing plate (3) is always biased in the opening direction by a spring (not shown) so that when the balloon (31) is deflated, it is automatically opened by the spring force.

In implementing the present invention, the closing plate (3) may be manually opened and closed, and the tube (6) may be inflated by an external air filling device (not shown).
The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the claims for utility model registration.
