〔従来の技術〕
作業用救命衣は、海水・淡水に没すれば10秒以
内に充気装置が作動して膨張しなければならない
と規定されている。[Prior Art] It is stipulated that when life jackets for work use are immersed in seawater or fresh water, the inflation device must operate and inflate within 10 seconds.
そのため充気装置は作業用救命衣の外面に露出
して取付けられ、充気装置には石膏センサが内蔵
され、これが水で溶解するとガス容器の封が切れ
て炭酸ガスを救命衣内に送り込み、救命衣を膨張
させるように構成されている。 For this reason, the air filling device is attached to the outside of the work life jacket, and a gypsum sensor is built into the air filling device. When this sensor dissolves in water, the seal on the gas container breaks and carbon dioxide gas is sent into the life jacket. The life jacket is configured to inflate.
ところが、作業用救命衣にはもう一つ、試験槽
内において、12個のノズルから合計3.76／分の
水を噴射させて行う散水試験で15分間内に膨張し

ればならない。
However, there is another regulation for work life jackets, which states that they must not inflate within 15 minutes in a water spray test conducted in a test tank by spraying water at a total of 3.76 minutes per minute from 12 nozzles. It must also be made so that it does not expand when exposed to normal waves or rain.
したがつて石膏センサを内蔵した従来の充気装
置では、上記の散水試験や、波浪・雨等を浴びた
場合にも作動してしまうという問題点がある。 Therefore, conventional air filling devices with built-in gypsum sensors have a problem in that they operate even during the above-mentioned water sprinkling test or when exposed to waves, rain, etc.
本発明は、作業用救命衣の充気装置における上

はない。 During normal times, the outer cover 27 is folded in to cover the inner cover 21 as shown in FIGS. Therefore, even in a water spray test, when water is sprayed by waves, rain, etc., the water from the top opening of the outer cover 27 travels along the outer surface of the inner cover 21, passes through the space 28, and falls from the hole 30 at the bottom, preventing the water from filling. Almost no air enters device A.
Water from below is blocked by the bottom surface of the outer cover 27 and does not enter the filling device A through the hole 14 of the cap 4.
緊急時には、フアスナ２９を外して外カバー２
７を第３図鎖線示のように広げると、水が下から
