ような型式の膨脹装置が開示される。Conventionally, automatic or manual inflating devices for swim bladders have been known, and for example, such a type of inflating device is disclosed in Japanese Patent Publication No. 46-3942.
第1図乃至第3図を参照し、更に詳細に説明する。A more detailed explanation will be given with reference to FIGS. 1 to 3.
第1図には浮袋へ圧縮流体を導入するための公知の圧縮
流体導入装置10を示す。FIG. 1 shows a known compressed fluid introduction device 10 for introducing compressed fluid into the swim bladder.
圧縮流体導入装置10は圧縮流体を収納する流体ポンベ
11と、該流体ボンベ11を装着する本体12とを備え
る。The compressed fluid introduction device 10 includes a fluid pump 11 that stores compressed fluid, and a main body 12 to which the fluid cylinder 11 is attached.
流体ボンベ11内の圧縮流体は封鎖板13により封鎖さ
れる。The compressed fluid in the fluid cylinder 11 is sealed off by a sealing plate 13 .
本体12の下端にはレバー14が軸15により枢着され
、レバー14に取付けたヒモ16を引くと押棒17を押
上げ、次いで押棒17と当接する針取付け台18を押上
げてその先端にある針19が封鎖板13を突破り、圧縮
流体が通路20.21を通って浮袋(図示せず)に導入
される。A lever 14 is pivotally attached to the lower end of the main body 12 by a shaft 15, and when a string 16 attached to the lever 14 is pulled, a push rod 17 is pushed up, and then a needle mount 18 that comes into contact with the push rod 17 is pushed up, and the needle mount 18 that is in contact with the push rod 17 is pushed up. The needle 19 breaks through the sealing plate 13 and compressed fluid is introduced through the passage 20.21 into the swim bladder (not shown).
本体12には海水電池22が本体と一体的に装着されて
おり、海水に浸漬すると発電し、導線23を通って電流
が点火玉24に流れ、火薬25を爆発させる。A seawater battery 22 is integrally attached to the main body 12, and when immersed in seawater, it generates electricity, and current flows through the conductor 23 to the ignition ball 24, causing the gunpowder 25 to explode.
火薬25が爆発すると、針取付け台18を押上げ、手動
の場合と同様に自動的に封鎖板13を突破り、圧縮流体
が浮袋に導入される。When the gunpowder 25 explodes, it pushes up the needle mount 18 and automatically breaks through the sealing plate 13 as in the manual case, and compressed fluid is introduced into the swim bladder.
この圧縮流体導入装置10の欠点は、約1缶程度で火薬
及び海水電池の交換が必要であるが、いずれも本体12
と一体的に構成されるため、火薬及び海水電池のみを交
換することは困難であり、実際上本体全体を取替えねば
ならなかった。The disadvantage of this compressed fluid introduction device 10 is that the gunpowder and seawater batteries need to be replaced after about one can;
Since it was constructed integrally with the main body, it was difficult to replace only the gunpowder and seawater batteries, and in fact the entire main body had to be replaced.
第2図には、第1図の装置と共に使用する公知の浮袋開
放装置30が示される。FIG. 2 shows a known bladder release device 30 for use with the device of FIG.
