Abstract

PURPOSE:To protect eyes and supply air or oxygen necessary for inspiration for a certain period of time in the condition with two hands put free by furnish ing a suction control device which supplies a supply gas from a pressure regulat ing device into a pair of glasses by means of the pressure difference of the suction pressure of a glasses wearer from the external pressure. CONSTITUTION:Two high pressure containers are screwed in on both sides of a frame 1 and fitted so as to enclose eyes and nose. In this condition, no air from high pressure containers will yet be supplied, but inhalation of air by nose lowers the air pressure in this frame 1 below the external pressure, and a diaphragm 16 of a suction control device 10 deflects to inside the frame 1. Now a push rod 17 retracts and the tip of a lever 18 is held fast, and a valve stem 19 advances through the lever action of the base end of the lever 18 to move an opening/closing valve 20, and thus the air passage of a valve seat 22 is opened. Thereby the air from an air tube 9 is sent through the perimeters of the valve stem 19 from the gaps around the opening/closing valve 20 to be introduced into the frame 1 from an opening in the base end of the lever 18.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a simple respiratory apparatus for emergency or leisure use underwater, or for emergency evacuation of a building fire or the like on land.

[Conventional technology]

Most of the deaths of crew members and passengers due to ship sinking are due to lack of oxygen while being trapped inside the ship, or the lack of breathing space from the time seawater enters the ship's cabin until it surfaces to the sea. It is said that this is due to the fact that they do not last long, and that they cannot open their eyes underwater and are unable to surface in a short time. The life vests provided in the cabin are meant to help you float above the sea if you jump from a sinking ship, and they do not mean anything to help you float away from a sinking ship, so they have little meaning in a sinking accident. .

In addition, the direct cause of fatal accidents caused by fires in buildings and hotels is not due to burning, but rather due to blindness due to smoke and toxic gas, lack of oxygen by the time they reach the emergency exits, etc.
Statistics show that this is because building materials and interior fittings generate toxic gases due to heat.

Conventionally, these emergency evacuation respirators have been provided in which the cylinder part is held in the hand and the breathing part is held in the mouth to breathe.

[Problem to be solved by the invention]

It is inconvenient to use a respirator in one's hands, for example when using an underwater light to illuminate the water or rescuing another person, since one's hands cannot be used freely. Even on land or in rescue operations from places where toxic gases are generated, only one hand can be used, which is inconvenient for carrying out items or carrying out rescue operations. Furthermore, this respirator alone has no effect on keeping your eyes open underwater or in smoke.

The present invention was made to solve these problems, and it protects the eyes when operating with the eyes open underwater or in smoke, and at the same time protects the eyes while keeping both hands free for a predetermined period of time. The purpose of the present invention is to provide a simple respirator that can supply the air or oxygen necessary for breathing.

[Means to solve the problem]

In order to achieve this purpose, the simple respiratory apparatus of the present invention consists of a pair of glasses that closely fit the face and cover the eyes, nose, or other organs including the mouth; A connection part for connecting the air supply port of a high-pressure cylinder, a pressure regulating device with a built-in pressure reduction mechanism and a safety mechanism, and a pressure regulator provided between the inside and outside of the frame of the glasses, and the pressure between the outside pressure and the inhalation pressure of the glasses wearer. The present invention is characterized by comprising an intake control device that differentially supplies the gas supplied from the pressure regulating device into the glasses.

〔Example〕

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention. In the figure, 1 is a frame of glasses that covers the eyes and nose, 2 is a heat-resistant/pressure-resistant glass, 3 is a rubber mask that brings the face frame 1 into close contact with the face, and 4 is a belt for attaching the frame 1 to the head. be.

On the left and right sides of the frame 1, there are bolts 7 as shown in FIG.
A pressure regulating device 5 is attached by a gasket 8, and a small high pressure cylinder 6 filled with high pressure air or oxygen is attached to the pressure regulating device 5. The air whose pressure has been reduced by the pressure regulator 5 is passed through the air tube 9 to the intake control device l.
O and supplied into frame 1.

FIG. 3 shows an embodiment of the pressure regulating device 5. As shown in FIG.

The high-pressure cylinder 6 is provided with a male thread 6a on the mouthpiece, and by screwing this into the connecting pipe 11, the tip of the negative pressure reducing valve 12 breaks through the sealing part of the high-pressure cylinder 6, and the high-pressure cylinder 6 is sealed. It will be canceled. - A narrow air passage is formed in the center of the pressure reducing valve 12, and its resistance reduces the pressure in the high pressure cylinder 6 from 185 to 195 kg/crl to approximately 8 to 10 kg/crl.

13 is a safety valve, and the pressure of the reduced air is 15 kg.
/cut or higher, it activates to prevent abnormally high pressure. 14 is a secondary pressure reducing valve which also serves as a connection plug, which further reduces the air pressure of approximately 8 to 10 kg/cJ to a positive pressure close to atmospheric pressure. The reduced pressure air is connected to the intake control device IO via an air tube 9.

FIG. 4 is a sectional view of the intake control device 10. A cap 15 has a plurality of openings, and is screwed into the frame 1 to tighten the diaphragm 16 at its edge. Inside the frame 1, which is watertightly or airtightly sealed by a diaphragm 16, a presser rod 17 that is movable back and forth and a lever type lever 18 that rotates when the presser rod 17 is pushed are built in. Lever 1
The base end of the valve shaft 8 is engaged with the tip of the valve shaft 19 . Valve stem 19
An on-off valve 20 that opens and closes air from the air tube 9 connected to the pressure regulator 5 described above is provided at the base end of the pressure regulator 5 . This on-off valve 20 is normally operated by a spring 21.
is closed by. 22 is a valve seat in which an air passage is formed. Furthermore, an exhaust valve 23 is provided at the front of the frame l for discharging air exhaled from the nose to the outside of the glasses.

When using glasses with this structure, two high-pressure cylinders 6 are screwed onto both sides of the frame 10, and the glasses are worn so as to cover the eyes and nose. In that state, air is not yet supplied from the high-pressure cylinder 6, but when air is inhaled through the nose, the air pressure inside the frame 1 becomes lower than the external pressure, and the diaphragm 16 of the intake control device IO shown in FIG. It bends inward. Then, the presser rod 17 retreats and at the same time the tip of the lever 18 is pressed. As a result, the valve shaft 19 moves forward due to the lever action of the lever 18, and the on-off valve 2o moves to open the air passage in the valve seat 22. As a result, air from the air tube 9 is introduced into the frame 1 from the gap around the on-off valve 20, around the valve shaft 19, and through the opening at the base end of the lever 18. When intake is stopped, the internal pressure and external pressure of the frame 1 are balanced, so the diaphragm 16 is restored, the on-off valve 20 is closed, and the supply of air from the pressure regulator 5 is stopped. The inhaled air can be expelled to the outside through the mouth outside the glasses, and when exhaled through the nose, the air becomes high pressure inside the frame 1, so it is exhausted to the outside by the exhaust valve 23.

In this way, it is possible to evacuate on land or at sea while saving air or oxygen supplied from the high-pressure cylinder 6.

By using two high-pressure cylinders 6 with a capacity of about 100 cc, the cylinders can be used for about 5 to 6 minutes with air at a filling pressure of about 190 kg/CrI. A used high-pressure cylinder can be used repeatedly by refilling it.

Moreover, by taking advantage of this simplicity, it can also be used for leisure activities such as underwater walks.

Note that the present invention is not limited to the structure of the above-described embodiments, and various modifications can be made within the scope of the purpose of the present invention.

For example, the pressure regulating device 5 can employ a pressure regulating valve mechanism. Instead of being connected to the intake control device 10 from outside the frame 1, the air tube 9 can be introduced into the intake control device 10 by forming an air passage inside the frame 1. Furthermore, although two high-pressure cylinders 6 are used in this embodiment, it is also possible to adopt a structure in which only one cylinder is used. Furthermore, the glasses can also be structured to cover the eyes, nose, and mouth, or the headpiece. Intake control device 10
The position of the pressure regulating device 5 can also be attached to the pressure regulating device 5 itself instead of the front side of the frame 1.

〔Effect of the invention〕

As explained above, in the present invention, the glasses cover the eyes, nose, or other organs including the mouth, and air regulated to a pressure suitable for intake is supplied from a small high-pressure cylinder into the glasses. I am planning to do so. As a result, even when evacuating on land through smoke or toxic gas due to a building fire, etc., by immediately donning the watch, you can protect your eyes and ensure breathing until the evacuation is complete. Even in the event of an underwater accident such as sinking, you can evacuate to the sea while keeping your eyes open and breathing underwater. moreover,
! ! It can be used not only for swimming, but also for diving, underwater leisure, etc.
