Description

The present invention relates to a full-face mask respirator attachment device for attaching respirators (self-contained underwater breathing apparatus and second stage pressure reduction section in air-supplied underwater breathing apparatus) to commercially available general-purpose full-face masks. .

Diving requires a mask to ensure visibility. In addition, a respirator is necessary to maintain breathing (excluding skin diving).

Currently, there are two ways to ensure visibility and breathing. One method is a mouthpiece method in which a mask is used only to secure the field of vision and a mouthpiece is held in the mouth as a respirator. Another method is the full-face mask method, which incorporates a respirator into the mask itself to ensure visibility.

Full-face masks allow you to breathe through your mouth and nose, so you can talk on land (on a ship) or between divers. Heavy-duty underwater work is also possible, and the scene of utilization is expanding from construction sites to road and port facility sites.

There are two types of full-face masks in terms of structure. One method is a full-scale product in which a respirator is completely incorporated into a full-face mask that is strong and durable enough to be used for a long period of time, and is highly safe. Another method is a simple method in which the user attaches the respirator with the mouthpiece removed to the rubber main body of a commercially available general-purpose full-face mask and secures it with a binding band.

The general-purpose full-face mask, in which the user attaches a respirator with the mouthpiece removed, can attach and detach the respirator, or return to the original mouthpiece method, and the fixed full-face mask They are often used because they are cheaper than full-face masks.

The user-installed respirator-mounted, universal full-face mask has a fatal flaw that has caused serious accidents around the world.

As shown in FIG. 1, a conventional general-purpose full-face mask 1 (hereinafter simply referred to as "conventional mask 1") that is attached to a respiratory apparatus by a user has a mask body 1a to be worn on the face made of soft rubber. The lens 2 of the mask body 1a is made of glass or transparent hard plastic. An outer tightening frame 4 consisting of an upper half portion 4a and a lower half portion 4b made of metal or hard plastic is fitted and fixed around the outer periphery of the portion 3 to form a watertight structure to prevent water leakage.

The peripheral face-mounting part 5 of the conventional mask 1 is made of soft rubber that is water-tight and retainable.

In the conventional mask 1, the portion corresponding to the diver's mouth 1a1 is formed with a cylindrical connecting portion 6 having an elliptical cross-section protruding outward, and an annular recessed portion 6a is formed on the outer peripheral surface of the distal end side of the connecting portion 6. An annular groove 6b is provided in the middle of the inner diameter surface on the base side.
The tubular mounting portion 7a1 of the case body 7a of the respirator 7 with the mouthpiece removed is inserted into the cylindrical connecting portion 6, and the tubular connecting portion 6 is mounted in the annular recessed groove 6b in the middle of the inner diameter surface on the base side of the cylindrical connecting portion 6. The annular convex portion 7b on the outer peripheral surface of the tip side of the portion 7a1 is fitted, and then the binding band 8 is wound around the annular recessed portion 6a on the outer peripheral surface on the tip side of the cylindrical connecting portion 6 of the conventional mask 1. The respirator 7 is fixed so as not to come off. Thus, in terms of function, it becomes the full-face mask described above.

The cylindrical connecting portion 6 of the conventional mask 1 is provided to be small so that the tubular mounting portion 7a1 of the case body 7a of the respirator 7 of all manufacturers can be attached.

There is no standard for the shape, such as size and height, of the mouthpiece of the respirator 7 , and as a result, it is forced to fit into the cylindrical connecting portion 6 of the conventional mask 1 .

Next, the load applied to the cylindrical connection portion 6 of the conventional mask 1 when the diver wears the conventional mask 1 and dives will be described.

A hose 9 for supplying medium-pressure air is arranged longer so as to fit everyone, and is curved when the conventional mask 1 is worn on the face. When medium-pressure air is sent, a straightening force acts on the hose 9 . Since the conventional mask 1 is fixed to the face by the wearing band 10 and held in place, the force is concentrated on the tubular joint 6 to which the respirator 7 is attached. The direction of this force is applied in all directions, front and back, left and right, and up and down.

In addition, since divers move their faces vertically and horizontally during diving, the cylindrical connecting portion 6 of the conventional mask 1 is also subjected to forces in various directions as described above.

In addition, since the air pressure in the conventional mask 1 fluctuates every time the diver breathes, a small amount of stress is constantly applied to the cylindrical connecting portion 6 of the conventional mask 1 .

The rubber body constituting the conventional mask 1 is deteriorated by ozone. Especially in the ocean, cracks occur due to strong exposure to "ozone".

As a result of the many adverse conditions described above, the base of the cylindrical connection part 6 of the conventional mask 1 suddenly cuts, and the respirator 7 comes off from the conventional mask 1, causing an accident in which the diver cannot breathe. do. When the base of the cylindrical connecting portion 6 of the conventional mask 1 is cut, water enters the conventional mask 1 through the cut hole and the diver instantly loses his sight. There have been several cases of breakage of the tubular connecting portion 6 of the conventional mask 1 and the respirator 7 in Japan, including fatal accidents.

Conventionally, as a countermeasure, in the industry, when using this conventional mask 1, it is instructed to dive with a spare "mask for securing visibility" and a spare "respirator with a mouthpiece". However, in practice, it is very difficult to use a spare mask or respirator when the respirator 7 comes off and the user loses his or her vision.

As a fixing method for preventing the respirator 7 of the conventional mask 1 from being detached, Patent Document 1 discloses a respiration regulator provided with a mouthpiece tubular portion formed in a tubular shape as a portion to which the mouthpiece can be fixed. As means for fixing to the full-face mask made of material, a plate-like member is provided inside the regulator mounting portion of the full-face mask 1 and inside the mouthpiece tube, and the plate-like member is placed inside the mouthpiece tube. The mouthpiece tube portion is inserted into and fixed to the regulator mounting portion of the full-face mask, and the regulator mounting portion of the full-face mask is extended by the plate member to the insertion length. A method for fixing a regulator of a full-face mask has been proposed, characterized in that the length of the mouthpiece tube portion is equal to or less than the length of the regulator mounting portion of the full-face mask so as to be compressed in the longitudinal direction. .
