【実施例】【Example】

以下、本考案を図示する実施例について具体的に説明する。 Hereinafter, embodiments of the present invention will be described in detail.

【0008】 この水中呼吸器10において、下パイプ部11は直管よりなり、ゴムバンド1 2により、使用者13のマスク14のベルトと結合され、使用者13の頭部に、 略上下方向に延びるように取付けられる。In the underwater breathing apparatus 10, the lower pipe portion 11 is made of a straight pipe, and is connected to the belt of the mask 14 of the user 13 by the rubber band 12 so that the head portion of the user 13 moves in a substantially vertical direction. Mounted to extend.

【0009】 この下パイプ部11の下端近くの中間部には、くわえ部15が結合して側方へ 延び、その先端16は口にくわえられるようになっている。A grip portion 15 is connected to an intermediate portion near the lower end of the lower pipe portion 11 and extends laterally, and a tip 16 of the grip portion 15 is gripped by a mouth.

【0010】 下パイプ部11の下端部には、下逆止弁17が設けられている。この下逆止弁 17は、下パイプ部11下端を閉じる蓋板18に孔19,…を形成し、さらにこ の下面に弁栓板20を接離可能に設けてなるものであつて、口から息を吐き出し たときに開いて、空気及び各所から侵入して下パイプ部11下部内に溜まってい る水21を外部へ排出させ、口で吸気するときには閉じて水の流入を防ぐ。なお 、下パイプ部11内には偏向板22が設けられ、口から吹き出した空気をくわえ 部15から下方へ向け下逆止弁17へ吹き付けるようにして、より排出が速やか になるようになっている。A lower check valve 17 is provided at the lower end of the lower pipe portion 11. The lower check valve 17 is formed by forming a hole 19, ... In a cover plate 18 that closes the lower end of the lower pipe portion 11, and further, by providing a valve plug plate 20 on the lower surface thereof so that the valve plug plate 20 can be contacted and separated. When it is exhaled from the air, it opens to let out the air and water 21 that has entered from various places and accumulated in the lower part of the lower pipe section 11 to the outside, and closes when inhaling with the mouth to prevent the inflow of water. A deflecting plate 22 is provided in the lower pipe portion 11 so that the air blown from the mouth is blown downward from the holding portion 15 to the lower check valve 17 so that the air can be discharged more quickly. There is.

【0011】 下パイプ部11の上端部には、上逆止弁23が設けられている。この上逆止弁 23は、下パイプ部11上端を閉じる蓋板24に孔25,…を形成し、さらにこ の下面に弁栓板26を接離可能に設けてなるものであって、口から息を吐き出し たときに閉じて、空気を下逆止弁17へ導き、口で吸気するときには開いて空気 を流入させる。An upper check valve 23 is provided at the upper end of the lower pipe section 11. The upper check valve 23 is formed by forming holes 25, ... In a lid plate 24 that closes the upper end of the lower pipe portion 11 and further by providing a valve plug plate 26 on the lower surface thereof so as to be able to come into contact with and separate from the mouth. When it is exhaled from the air, it is closed to guide air to the lower check valve 17, and when it is inhaled by the mouth, it is opened to let air flow in.

【0012】 下パイプ部11の上端には、可撓パイプ27が接続されている。この可撓パイ プ27は柔軟なプラスチック製であり、水圧で潰れることなくかつ自由に曲折す ることができる。なお、この可撓パイプ27は使用状態に応じて各種の長さのも のを適宜交換し得るようにしておくとよい。A flexible pipe 27 is connected to the upper end of the lower pipe portion 11. The flexible pipe 27 is made of flexible plastic and can be bent freely without being crushed by water pressure. It should be noted that the flexible pipe 27 may have various lengths that can be appropriately exchanged depending on the use condition.

【0013】 浮体28は、ほぼ全体が発泡プラスチック製であり、下面に金属製の重り29 を有し、このため水面に浮きかつ転倒することなくその姿勢を維持する。The floating body 28 is almost entirely made of foamed plastic, and has a metal weight 29 on the lower surface thereof, so that it floats on the water surface and maintains its posture without falling.

【0014】 浮体28には上パイプ部30が貫通して支持され、この上パイプ部30の上端 は空中に延びて略U字状に曲折され、口端から水しぶきが入ることがないように され、下端は水中に延び、その先端に可撓パイプ27が接続される。An upper pipe portion 30 penetrates and is supported by the floating body 28, and an upper end of the upper pipe portion 30 extends in the air and is bent into a substantially U shape so that water spray does not enter from the mouth end. The lower end extends into the water, and the flexible pipe 27 is connected to the front end.

【0015】 この水中呼吸器10は、以上の構成であるから、図1に示すようにして使用さ れる。すなわち、下パイプ部11を使用者の頭部に取付け、口にくわえ部先端1 6をくわえ、浮体28を水上に浮かせて水中に潜る。こうすると、息を吐き出し たとき空気は下逆止弁17から水中に排出され、息を吸ったとき空気は空中から 上パイプ部30、可撓パイプ27、上逆止弁23を経て導入され、呼吸ができる 。The underwater respirator 10 is used as shown in FIG. 1 because of the above-mentioned configuration. That is, the lower pipe portion 11 is attached to the user's head, the gripper tip 16 is gripped in the mouth, and the floating body 28 is floated above the water to dive into the water. Thus, when exhaling, air is discharged into the water from the lower check valve 17, and when inhaling, air is introduced from the air through the upper pipe portion 30, the flexible pipe 27, and the upper check valve 23. I can breathe.

【考案の効果】[Effect of device]

本考案の水中呼吸器は、上述のように、ボンベ等を有さず、単に口と空中とを パイプで接続しただけの簡単な構成であるので、手軽に使用することができる。 また、浮体、可撓パイプを有するので、シュノーケルを使用することのできない 、水面より下の水中で呼吸をすることができる。勿諭、空気を加圧するものでな いから、深いところでの使用は不可能であるが、実験によれば、1メートル程度 の水深では支障なく使用することができる。 The underwater respirator of the present invention, as described above, does not have a cylinder or the like and has a simple structure in which the mouth and the air are simply connected by a pipe, so that it can be used easily. Also, since it has a floating body and a flexible pipe, it is not possible to use a snorkel, and it is possible to breathe in water below the water surface. Of course, since it does not pressurize the air, it cannot be used in deep places, but experiments have shown that it can be used without problems at a water depth of about 1 meter.
