Description

本発明は、着脱可能な膨張式救命胴衣を備えたハーネス型安全帯に関する。   The present invention relates to a harness-type safety belt provided with a detachable inflatable life jacket.

海、湖沼、河川における水難事故において、水難者の安全を確保するための救命胴衣（ライフジャケット）として、ガスなどの気体によって気室部材を膨張させる膨張式救命胴衣がある（例えば、特許文献１参照）。   As a life jacket for securing the safety of a person suffering from a water accident in the sea, a lake, a river, or a river, there is an inflatable life jacket that inflates an air chamber member with a gas such as gas (for example, Patent Document 1). reference).

このような膨張式救命胴衣は、水難事故が発生する前の通常時には気室部材が萎んでいるため、港湾や河川敷などの水辺で作業を行う作業者（着用者とも言う）が着用するのに適している。   Such inflatable life jackets are worn by workers (also known as wearers) who work on the waterside, such as in harbors and riverbeds, because the air chamber members are usually deflated before a flood accident occurs. Are suitable.

また、高所作業において、作業者の落下防止のためにハーネス型安全帯が用いられている。   In work at high places, a harness-type safety belt is used to prevent workers from falling.

このため、水辺で高所作業を行うためには、作業者はハーネス型安全帯と膨張式救命胴衣との両方を着用しなくてはならない。   For this reason, in order to perform the work at heights at the waterside, the worker must wear both the harness type safety belt and the inflatable life jacket.

なお、落石防護用救命胴衣に墜落防止用安全帯を一体型に構成したものも提案されている（例えば、特許文献２参照）。   In addition, there has also been proposed a structure in which a fall prevention safety band is integrally formed with a life fall jacket for rock fall protection (for example, see Patent Document 2).

特開２００６−１９３１０５号公報JP 2006-193105 A 特開２０１５−１４０５０５号公報JP 2015-140505 A

しかしながら、水辺で高所作業を行う作業者は、膨張式救命胴衣とハーネス型安全帯との両方を着用しなくてはならないが、膨張式救命胴衣とハーネス型安全帯とを個別に脱着するのは煩雑であるという問題がある。
また、構造によっては膨張式救命胴衣の背ベルトがハーネス型安全帯の背中に設けられたＤ環に干渉してしまい、ハーネス型安全帯の墜落防止性能に影響を及ぼす恐れがある。 However, workers performing high-altitude work at the waterside must wear both the inflatable life jacket and the harness-type safety belt. Is complicated.
Further, depending on the structure, the back belt of the inflatable life jacket may interfere with the D-ring provided on the back of the harness type safety belt, which may affect the fall prevention performance of the harness type safety belt.

このため、膨張式救命胴衣をハーネス型安全帯に一体的に固定する方法も考えられるものの、単体で使用可能な膨張式救命胴衣は、首が脱落しないように顎下において端部同士が近接して配置されたＶ字形状の開口となる形状を有するため、このような膨張式救命胴衣をハーネス型安全帯に固定すると、膨張式救命胴衣によってハーネス型安全帯の胸ベルトが覆われてしまい、胸ベルトの操作が困難になり、ハーネス型安全帯の脱着が煩雑になるという問題がある。   For this reason, although a method of integrally fixing the inflatable life jacket to the harness-type safety belt is also conceivable, the inflatable life jacket that can be used as a single unit has its ends close to each other under the chin so that the neck does not fall off. When such an inflatable life jacket is fixed to a harness-type safety belt, the chest belt of the harness-type safety belt is covered by the inflatable life jacket, There is a problem that the operation of the chest belt becomes difficult, and the attaching and detaching of the harness type safety belt becomes complicated.

また、膨張式救命胴衣の胸部の端部をハーネス型安全帯の肩ベルト部に固定すると、膨張式救命胴衣の両端部が離れてしまい、着用者の顎下に空間が形成され、気室部材が膨張した際に顎下に気室部材が配置され難い。着用者の顎下に膨張した気室部材が配置されないと着用者の顎を確実に浮かすことができず、着用者の浮遊姿勢が安定した後傾とならずに垂直に近い浮遊姿勢となり、着用者の口元を水面から離すことができなくなってしまう。   Further, when the end of the chest of the inflatable life jacket is fixed to the shoulder belt of the harness type safety belt, both ends of the inflatable life jacket are separated, and a space is formed under the chin of the wearer, and the air chamber member is formed. It is difficult for the air chamber member to be placed under the chin when the swells. If the inflated air chamber member is not placed under the wearer's chin, the wearer's chin cannot be reliably lifted, and the wearer's floating posture becomes stable and does not tilt after taking on a nearly vertical floating posture, and is worn Can not keep the mouth of the person away from the water surface.

また、膨張式救命胴衣をハーネス型安全帯に固定して一体化してしまうと、水辺以外の作業でハーネス型安全帯を単体で利用できず、作業性が低下してしまうと共に、別途、単体のハーネス型安全帯だけを用意する必要があり、高コストになってしまうという問題がある。   Also, if the inflatable life jacket is fixed to the harness-type safety belt and integrated, the harness-type safety belt cannot be used alone for work other than waterside, and workability will be reduced. It is necessary to prepare only a harness type safety belt, and there is a problem that the cost becomes high.

このため、ハーネス型安全帯に着脱可能で、且つハーネス型安全帯に装着した際に着用者を安全に保護することができる最適化された膨張式救命胴衣が望まれている。   For this reason, there is a demand for an optimized inflatable life jacket that can be attached to and detached from a harness-type safety band, and that can protect a wearer safely when worn on the harness-type safety band.

本発明はこのような事情に鑑み、膨張式救命胴衣をハーネス型安全帯に着脱可能としてハーネス型安全帯を単体で利用することができ、作業性を向上してコストを低減することができると共に、膨張式救命胴衣が固定されたハーネス型安全帯を作業者が容易に脱着することができ、且つ膨張式救命胴衣によって着用者の浮遊姿勢を安定させて安全に保護することができる着脱式の膨張式救命胴衣を備えたハーネス型安全帯を提供することを課題とする。   In view of such circumstances, the present invention allows the inflatable life jacket to be attached to and detached from the harness-type safety belt so that the harness-type safety belt can be used alone, thereby improving workability and reducing costs. The detachable type, which allows the worker to easily attach and detach the harness-type safety belt to which the inflatable life jacket is fixed, and stabilize the floating posture of the wearer with the inflatable life jacket to protect safely. An object of the present invention is to provide a harness-type safety belt having an inflatable life jacket.

なお、図２に示すように、右下部取付部６４は、ハーネス型安全帯１０の右肩ベルト部１４の右胸ベルト２６が接続された部分よりも下側に固定される位置に設けられ、左下部取付部６６は、左肩ベルト部１５の左胸ベルト２７が接続された部分よりも下側に固定されるように設けられている。右下部取付部６４及び左下部取付部６６を胸ベルトよりも下側の右肩ベルト部１４及び左肩ベルト部１５に固定することで、気室部材５０を膨張させて着用者１を水に浮かせた際に、右下部取付部６４及び左下部取付部６６が右肩ベルト部１４及び左肩ベルト部１５を上側に移動するのを胸ベルトによって規制することができる。したがって、右下部取付部６４及び左下部取付部６６が右肩ベルト部１４及び左肩ベルト部１５を上側に移動することを防止して、着用者１の姿勢が垂直に近づき難くすることができ、着用者１の口元を水面から離すことができ、安全性を向上することができる。なお、右下部取付部６４及び左下部取付部６６を右肩ベルト部１４及び左肩ベルト部１５の胸ベルトが接続された部分よりも上側に固定してもよいが、この場合、気室部材５０を膨張させて着用者１を水に浮かせた際に、右下部取付部６４及び左下部取付部６６が右肩ベルト部１４及び左肩ベルト部１５を上側に移動し、ハーネス型安全帯１０の右肩ベルト部１４及び左肩ベルト部１５の下方、すなわち、胸ベルトよりも下側と膨張式救命胴衣４０とが離れてしまい、着用者１の浮遊姿勢が垂直に近くなり、着用者１の口元が水面に近づくため好ましくない。さらに、右下部取付部６４及び左下部取付部６６を胸ベルトに固定しても良いが、胸ベルトは、胸ベルト用連結具２８、２９によって分離可能となっているため、胸ベルトを分離した際に胸ベルトが環状の右下部取付部６４及び左下部取付部６６から不意に抜けてしまう虞があり、抜けたまま着用すると安全性が低下するため好ましくない。本実施形態では、右下部取付部６４及び左下部取付部６６のそれぞれは、右肩ベルト部１４及び左肩ベルト部１５に固定されるため、右下部取付部６４及び左下部取付部６６が右肩ベルト部１４及び左肩ベルト部１５から不意に抜けてしまうのを防止して、安全性を向上することができる。   In addition, as shown in FIG. 2, the lower right attachment portion 64 is provided at a position fixed below the portion where the right chest belt 26 of the right shoulder belt portion 14 of the harness type safety belt 10 is connected, The lower left attachment portion 66 is provided so as to be fixed below the portion of the left shoulder belt portion 15 to which the left chest belt 27 is connected. By fixing the lower right mounting portion 64 and the lower left mounting portion 66 to the right shoulder belt portion 14 and the left shoulder belt portion 15 below the chest belt, the air chamber member 50 is expanded to float the wearer 1 on the water. In this case, the chest belt can restrict the lower right mounting portion 64 and the lower left mounting portion 66 from moving the right shoulder belt portion 14 and the left shoulder belt portion 15 upward. Therefore, it is possible to prevent the lower right mounting portion 64 and the lower left mounting portion 66 from moving the right shoulder belt portion 14 and the left shoulder belt portion 15 upward, thereby making it difficult for the posture of the wearer 1 to approach vertical, The mouth of the wearer 1 can be separated from the water surface, and safety can be improved. In addition, the lower right mounting part 64 and the lower left mounting part 66 may be fixed above the part of the right shoulder belt part 14 and the left shoulder belt part 15 to which the chest belt is connected, but in this case, the air chamber member 50 When the wearer 1 is floated on the water by inflating the lower part, the lower right mounting part 64 and the lower left mounting part 66 move the right shoulder belt part 14 and the left shoulder belt part 15 upward, and the right side of the harness type safety belt 10 is moved. The inflatable life jacket 40 is separated from the lower part of the shoulder belt portion 14 and the left shoulder belt portion 15, that is, the lower side of the chest belt, and the floating posture of the wearer 1 becomes almost vertical, and the mouth of the wearer 1 becomes closer. It is not preferable because it approaches the water surface. Further, the lower right mounting portion 64 and the lower left mounting portion 66 may be fixed to the chest belt. However, the chest belt can be separated by the chest belt connectors 28 and 29. At this time, there is a possibility that the chest belt may fall out of the annular lower right attachment portion 64 and left lower attachment portion 66 unexpectedly, and it is not preferable to wear the chest belt without the attachment because safety is reduced. In the present embodiment, the lower right mounting portion 64 and the lower left mounting portion 66 are fixed to the right shoulder belt portion 14 and the left shoulder belt portion 15, respectively. It is possible to prevent accidental removal from the belt portion 14 and the left shoulder belt portion 15 and to improve safety.

また、右下部取付部６４及び左下部取付部６６は、ハーネス型安全帯１０及び膨張式救命胴衣４０の自重によって着用者１に押しつけられ難いため、凹凸が形成されていても異物感及び痛みを感じ難い。したがって、右下部取付部６４及び左下部取付部６６は、着脱し易い取付部用連結具６７、６８によって固定するのが好ましい。これにより、操作性を向上して着脱性を向上することができる。   In addition, since the lower right attachment portion 64 and the lower left attachment portion 66 are hard to be pressed against the wearer 1 by the weight of the harness type safety band 10 and the inflatable life jacket 40, the feeling of foreign matter and the pain are formed even when the unevenness is formed. Hard to feel. Therefore, it is preferable that the lower right mounting portion 64 and the lower left mounting portion 66 be fixed by the mounting portion couplers 67 and 68 which are easily detachable. Thereby, operability can be improved and detachability can be improved.

また、カバー部材６０の最上部には、背ベルト８０の一端が固定されている。また、カバー部材６０の両方の下端部には、救命胴衣用腰ベルト７０が固定されている。背ベルト８０の他端は、救命胴衣用腰ベルト７０に固定されている。本実施形態では、図１に示すように、背ベルト８０及び救命胴衣用腰ベルト７０は、カバー部材６０の後面カバー部６１に縫い付けられて固定されている。また、救命胴衣用腰ベルト７０の両端部には、互いに着脱可能な連結具７１が設けられており、着用者１の胸部分に着用することができる。もちろん、救命胴衣用腰ベルト７０は、端部を連結具７１に通して折り返し、救命胴衣用腰ベルト７０を重ねた状態で維持するリング（図示なし）が設けられており、リングによって救命胴衣用腰ベルト７０の長さが調整可能となっている。   One end of a back belt 80 is fixed to the top of the cover member 60. A waist belt 70 for a life jacket is fixed to both lower ends of the cover member 60. The other end of the back belt 80 is fixed to a waist belt 70 for a life jacket. In the present embodiment, as shown in FIG. 1, the back belt 80 and the waist belt 70 for a life jacket are sewn and fixed to the rear cover 61 of the cover member 60. At both ends of the waist belt 70 for a life jacket, connecting members 71 that are detachable from each other are provided, and can be worn on the chest portion of the wearer 1. Of course, the waist belt 70 for the life jacket is provided with a ring (not shown) for folding the end portion through the connecting member 71 and maintaining the waist belt 70 for the life jacket in an overlapped state. The length of the waist belt 70 is adjustable.

このような膨張式救命胴衣４０では、救命胴衣用腰ベルト７０及び背ベルト８０を設けることによって、膨張式救命胴衣４０をハーネス型安全帯１０に固定することなく、図７に示すように、膨張式救命胴衣４０を単体で着用者１が着用することができる。ちなみに、膨張式救命胴衣４０に救命胴衣用腰ベルト７０及び背ベルト８０が設けられていないと、膨張式救命胴衣４０を単体で着用者１が着用した場合、膨張式救命胴衣４０を首だけで支えることになるため、着用者１を安全に浮遊させることができないため、使用することはできない。   In such an inflatable life jacket 40, by providing the waist belt 70 and the back belt 80 for the life jacket, the inflatable life jacket 40 can be inflated without being fixed to the harness type safety belt 10 as shown in FIG. The wearable body 1 can be worn by the wearer 1 alone. By the way, if the inflatable life jacket 40 is not provided with the waist belt 70 and the back belt 80 for the life jacket, when the wearer 1 wears the inflatable life jacket 40 alone, the inflatable life jacket 40 is held only by the neck. Since it is supported, the wearer 1 cannot safely float and cannot be used.

このようなカバー部材６０の後面カバー部６１と前面カバー部６２との間に気室５１に気体が充填されていない気室部材５０が収容される。   The air chamber member 50 in which the gas is not filled in the air chamber 51 is accommodated between the rear cover 61 and the front cover 62 of the cover member 60.

ここで、図６に示すように、気室部材５０は、カバー部材６０に固定されている。本実施形態の気室部材５０は、右胸部５２の下端部をカバー部材６０に固定する右胸固定部９０と、左胸部５３の下端部をカバー部材６０に固定する左胸固定部９１と、首部５４をカバー部材６０に固定する首固定部９２と、によってカバー部材６０に固定されている。   Here, as shown in FIG. 6, the air chamber member 50 is fixed to the cover member 60. The air chamber member 50 of the present embodiment includes a right chest fixing portion 90 for fixing the lower end of the right chest 52 to the cover member 60, a left chest fixing portion 91 for fixing the lower end of the left chest 53 to the cover member 60, The neck portion 54 is fixed to the cover member 60 by a neck fixing portion 92 for fixing the neck portion 54 to the cover member 60.

右胸固定部９０は、ベルトからなり、一端部がカバー部材６０に固定され、他端部が右胸部５２の下端部の幅方向の外側に固定されている。ここで、右胸部５２の幅方向とは、右胸部５２と左胸部５３との並び方向のことである。また、右胸固定部９０の他端部が右胸部５２の幅方向の外側に固定されているとは、右胸固定部９０が右胸部５２の幅方向の中央よりも外側、すなわち、左胸部５３とは反対側に固定されていることを言う。また、右胸部５２の幅方向の中央とは、右胸部５２の最も広い部分における中央のことである。これにより、右胸固定部９０によって右胸部５２の下端部は、外側がカバー部材６０に固定されている。このため、気室部材５０の気室５１内に気体が充填されて気室部材５０が膨張した際に、図６（ｂ）に示すように、右胸部５２は右胸固定部９０よりも内側、すなわち、着用者１の中心線側に向かって膨張する。つまり、右胸部５２が右胸固定部９０よりも内側に膨張するとは、右胸部５２の右胸固定部９０よりも外側よりも内側の方が大きく膨張することを言う。このように、右胸部５２の右胸固定部９０よりも内側に向かって膨張させることで、図７（ｂ）及び図８（ｂ）に示すように、着用者１の顎下に気室部材５０を配置して、着用者１の顎下の浮力を確保することができ、着用者１を正しい姿勢で水に浮かせることができる。なお、右胸固定部９０の一端部は、本実施形態では、後面カバー部６１に固定されている。これは、膨張式救命胴衣４０を単体で着用者１が着用した際に、救命胴衣用腰ベルト７０は後面カバー部６１に固定されているため、図７（ｂ）に示すように、気室部材５０が膨張した際に後面カバー部６１が幅方向にずれ難く、膨張した気室部材５０の右胸部５２が着用者１の中心線から外側に向かってずれ難いからである。また、膨張式救命胴衣４０をハーネス型安全帯１０に固定した状態では、後面カバー部６１は、右肩ベルト部１４に固定されるため、図８（ｂ）に示すように、気室部材５０が膨張した際に後面カバー部６１が幅方向にずれ難く、膨張した気室部材５０の右胸部５２が着用者１の中心線から外側に向かってずれ難いからである。   The right chest fixing portion 90 is formed of a belt, one end of which is fixed to the cover member 60, and the other end of which is fixed outside the lower end of the right chest 52 in the width direction. Here, the width direction of the right chest 52 is the direction in which the right chest 52 and the left chest 53 are arranged. The other end of the right chest fixing part 90 is fixed to the outside of the right chest 52 in the width direction, which means that the right chest fixing part 90 is located outside the center of the right chest 52 in the width direction, that is, the left chest. It means that it is fixed on the opposite side to 53. The center in the width direction of the right chest 52 is the center of the widest part of the right chest 52. Thus, the lower end of the right chest 52 is fixed to the cover member 60 on the outside by the right chest fixing portion 90. Therefore, when the gas is filled in the air chamber 51 of the air chamber member 50 and the air chamber member 50 expands, as shown in FIG. 6B, the right chest 52 is located inside the right chest fixing part 90. That is, it expands toward the center line side of the wearer 1. That is, the expression that the right chest 52 expands more inward than the right chest fixing part 90 means that the right chest 52 expands more inside the right chest fixing part 90 than outside the right chest fixing part 90. In this way, by inflating the right chest part 52 inward from the right chest fixing part 90, as shown in FIGS. 7B and 8B, the air chamber member is placed under the chin of the wearer 1. By arranging 50, the buoyancy under the chin of the wearer 1 can be secured, and the wearer 1 can be floated on the water in a correct posture. In this embodiment, one end of the right chest fixing portion 90 is fixed to the rear cover 61. This is because when the wearer 1 wears the inflatable life jacket 40 alone, the waist belt 70 for the life jacket is fixed to the rear cover portion 61, and as shown in FIG. This is because, when the member 50 expands, the rear cover 61 is unlikely to shift in the width direction, and the right chest portion 52 of the expanded air chamber member 50 does not easily shift outward from the center line of the wearer 1. When the inflatable life jacket 40 is fixed to the harness-type safety belt 10, the rear cover 61 is fixed to the right shoulder belt 14, so that as shown in FIG. This is because the rear cover portion 61 is unlikely to shift in the width direction when is expanded, and the right chest portion 52 of the expanded air chamber member 50 is unlikely to shift outward from the center line of the wearer 1.

左胸固定部９１は、ベルトからなり、一端部がカバー部材６０に固定され、他端部が左胸部５３の下端部の幅方向の外側に固定されている。ここで、左胸部５３の幅方向とは、右胸部５２及び左胸部５３の並び方向のことである。また、左胸固定部９１の他端部が左胸部５３の外側に固定されているとは、左胸固定部９１が左胸部５３の幅方向の中央よりも外側、すなわち、右胸部５２とは反対側に固定されていることを言う。また、左胸部５３の幅方向の中央とは、左胸部の最も広い部分における中央のことである。これにより、左胸固定部９１によって左胸部５３の下端部は、外側がカバー部材６０に固定されている。このため、気室部材５０の気室５１内に気体が充填されて気室部材５０が膨張した際に、左胸部５３は左胸固定部９１よりも内側、すなわち、着用者１の中心線側に向かって膨張する。つまり、左胸部５３が左胸固定部９１よりも内側に膨張するとは、左胸部５３の左胸固定部９１よりも外側より内側の方が大きく膨張することを言う。このように、左胸部５３の左胸固定部９１よりも内側に向かって膨張させることで、図７（ｂ）及び図８（ｂ）に示すように、着用者１の顎下に気室部材５０を配置して、着用者１の顎下の浮力を確保することができ、着用者１を正しい姿勢で水に浮かせることができる。なお、左胸固定部９１の一端部は、後面カバー部６１に固定されている。これは上述した右胸固定部９０と同様に、後面カバー部６１には、救命胴衣用腰ベルト７０が固定されていると共に、後面カバー部６１がハーネス型安全帯１０の左肩ベルト部１５に固定されるため、後面カバー部６１は、幅方向にずれ難く、膨張した気室部材５０の左胸部５３が着用者１の中心線から外側に向かってずれ難いからである。   The left chest fixing portion 91 is formed of a belt, one end of which is fixed to the cover member 60, and the other end of which is fixed outside the lower end of the left chest 53 in the width direction. Here, the width direction of the left chest 53 is the direction in which the right chest 52 and the left chest 53 are arranged. The other end of the left chest fixing portion 91 is fixed to the outside of the left chest 53, which means that the left chest fixing portion 91 is outside the center of the left chest 53 in the width direction, that is, the right chest 52 Say that it is fixed on the other side. The widthwise center of the left chest 53 is the center of the widest part of the left chest. Thus, the lower end of the left chest 53 is fixed to the cover member 60 on the outside by the left chest fixing portion 91. For this reason, when the gas is filled in the air chamber 51 of the air chamber member 50 and the air chamber member 50 expands, the left chest 53 is located inside the left chest fixing portion 91, that is, the center line side of the wearer 1. Inflates towards. That is, the expression that the left chest 53 expands more inward than the left chest fixing part 91 means that the inside of the left chest 53 expands more inside than the left chest fixing part 91. In this way, by inflating the left chest part 53 inward from the left chest fixing part 91, as shown in FIGS. 7B and 8B, the air chamber member is placed under the chin of the wearer 1. By arranging 50, the buoyancy under the chin of the wearer 1 can be secured, and the wearer 1 can be floated on the water in a correct posture. Note that one end of the left chest fixing portion 91 is fixed to the rear cover 61. This is similar to the right chest fixing portion 90 described above, in which the waist belt 70 for a life jacket is fixed to the rear cover portion 61 and the rear cover portion 61 is fixed to the left shoulder belt portion 15 of the harness type safety belt 10. Therefore, the rear cover 61 is unlikely to shift in the width direction, and the left chest 53 of the inflated air chamber member 50 is unlikely to shift outward from the center line of the wearer 1.

首固定部９２は、ベルトからなり、一端がカバー部材６０に固定され、他端部が首部５４の内側に固定されている。首固定部９２の一端は、カバー部材６０の後面カバー部６１に固定されている。これにより、着用者１の首と首部５４との間に空間が生じ難く、着用者１の後頭部を首部５４によって支えることができる。   The neck fixing portion 92 is formed of a belt, and one end is fixed to the cover member 60 and the other end is fixed inside the neck portion 54. One end of the neck fixing part 92 is fixed to the rear cover part 61 of the cover member 60. This makes it difficult for a space to be formed between the neck of the wearer 1 and the neck 54, and the back of the wearer 1 can be supported by the neck 54.

このように、図６（ｂ）に示すように、右胸固定部９０の下端部と左胸固定部９１の下端部との外側をカバー部材６０に固定することによって、気室部材５０の気室５１内に気体を充填して膨張させた際に、カバー部材６０の下端部同士が離れた位置にあっても、右胸部５２、左胸部５３及び首部５４によって形成される空間をＶ字形状に、すなわち、右胸部５２と左胸部５３との両端部の内面同士を互いに当接させた状態とすることができる。   In this manner, as shown in FIG. 6B, by fixing the outside of the lower end of the right chest fixing portion 90 and the lower end of the left chest fixing portion 91 to the cover member 60, the air chamber member 50 is air-tight. When the chamber 51 is filled with gas and inflated, the space formed by the right chest 52, the left chest 53, and the neck 54 is V-shaped even when the lower ends of the cover members 60 are separated from each other. That is, the inner surfaces of both ends of the right chest 52 and the left chest 53 can be brought into contact with each other.

すなわち、膨張式救命胴衣４０を単体で使用する場合、図７（ａ）に示すように、救命胴衣用腰ベルト７０によってカバー部材６０の両端部が着用者１の中心線よりも外側に離れた位置に配置されても、気室部材５０は両端部において外側が右胸固定部９０及び左胸固定部９１によってカバー部材６０に固定されることで、図７（ｂ）に示すように気室部材５０が膨張した際に、気室部材５０は、カバー部材６０との固定部分である右胸固定部９０及び左胸固定部９１よりも内側に向かって膨張することで、気室部材５０を着用者１の顎下に配置して、着用者１の顎下の浮力を確保することができる。   That is, when the inflatable life jacket 40 is used alone, both ends of the cover member 60 are separated outward from the center line of the wearer 1 by the waist belt 70 for the life jacket as shown in FIG. Even if the air chamber member 50 is disposed at the position, the outside of the air chamber member 50 is fixed to the cover member 60 by the right chest fixing portion 90 and the left chest fixing portion 91 at both ends, so that the air chamber member as shown in FIG. When the member 50 is inflated, the air chamber member 50 expands inward from the right chest fixing portion 90 and the left chest fixing portion 91 which are fixed portions to the cover member 60, thereby causing the air chamber member 50 to expand. The buoyancy below the chin of the wearer 1 can be ensured by disposing the buoyancy below the chin of the wearer 1.

ちなみに、気室部材５０の両端部において、その内側が右胸固定部９０及び左胸固定部９１によってカバー部材６０に固定されていると、右胸部５２及び左胸部５３の端部同士が離れてしまい、着用者１の顎下に空間が形成されてしまう。このように着用者１の顎下に気室部材５０が配置されないと顎を確実に浮かすことができずに、着用者１の浮遊姿勢が安定せずに垂直に近い浮遊姿勢になり、口元を水面から離すことができなくなってしまう。   Incidentally, when the inside of the air chamber member 50 is fixed to the cover member 60 by the right chest fixing portion 90 and the left chest fixing portion 91 at both ends, the ends of the right chest 52 and the left chest 53 are separated from each other. As a result, a space is formed below the chin of the wearer 1. If the air chamber member 50 is not arranged under the chin of the wearer 1 as described above, the chin cannot be reliably lifted, and the floatation posture of the wearer 1 becomes unstable and becomes a nearly vertical floating posture. It cannot be separated from the water surface.

本実施形態では、カバー部材６０の端部同士が離れていても、気室部材５０は両端部において外側が右胸固定部９０及び左胸固定部９１によってカバー部材６０に固定されることで、気室部材５０が膨張した際に、気室部材５０を着用者１の顎下に配置して、着用者１の顎下の浮力を確保することができ、着用者１を後傾の斜めに浮遊させて、口元を水面から離すことができる。   In the present embodiment, even when the ends of the cover member 60 are separated from each other, the outside of the air chamber member 50 is fixed to the cover member 60 by the right chest fixing portion 90 and the left chest fixing portion 91 at both ends. When the air chamber member 50 is inflated, the air chamber member 50 can be arranged below the chin of the wearer 1 to ensure buoyancy below the chin of the wearer 1, and the wearer 1 can be tilted backward and obliquely. The mouth can be separated from the water surface by floating.

また、本実施形態の膨張式救命胴衣４０は、カバー部材６０の着用者１の首に接触する内側とは反対側の外側が開口するため、開口に設けられた面ファスナー等が着用者１の首に接触することがない。したがって、膨張式救命胴衣４０を着用した際の擦れが生じることがない。   In addition, in the inflatable life jacket 40 of the present embodiment, since the outside of the cover member 60 on the opposite side to the inside that comes into contact with the neck of the wearer 1 is opened, the hook-and-loop fastener provided at the opening is provided by the wearer 1. No contact with the neck. Therefore, rubbing does not occur when the inflatable life jacket 40 is worn.

また、本実施形態の膨張式救命胴衣４０は、図１、図２及び図８に示すように、カバー部材６０の右上部取付部６３及び右下部取付部６４を右肩ベルト部１４に固定すると共に、左上部取付部６５及び左下部取付部６６を左肩ベルト部１５に取り付けることで、ハーネス型安全帯１０に装着される。すなわち、膨張式救命胴衣４０は、ハーネス型安全帯１０を介して着用者１に固定することができるため、膨張式救命胴衣４０の救命胴衣用腰ベルト７０を着用者１が適切な長さで装着する必要がない。もちろん、膨張式救命胴衣４０をハーネス型安全帯１０に装着した場合であっても、膨張式救命胴衣４０の救命胴衣用腰ベルト７０を着用者１に適切な長さで装着すれば、さらに安全性を高めることができる。   In addition, in the inflatable life jacket 40 of the present embodiment, as shown in FIGS. 1, 2, and 8, the upper right mounting portion 63 and the lower right mounting portion 64 of the cover member 60 are fixed to the right shoulder belt portion 14. At the same time, the upper left attachment portion 65 and the lower left attachment portion 66 are attached to the left shoulder belt portion 15 so as to be attached to the harness type safety belt 10. That is, since the inflatable life jacket 40 can be fixed to the wearer 1 via the harness-type safety belt 10, the wearer 1 attaches the waist belt 70 for the life jacket of the inflatable life jacket 40 to an appropriate length. No need to attach. Of course, even when the inflatable life jacket 40 is attached to the harness-type safety belt 10, if the inflatable life jacket 40 has the waist belt 70 for the life jacket attached to the wearer 1 with an appropriate length, the safety is further improved. Can be enhanced.

そして、右下部取付部６４を右肩ベルト部１４に取り付けると共に、左下部取付部６６を左肩ベルト部１５に取り付けることで、膨張式救命胴衣４０は、右肩ベルト部１４と左肩ベルト部１５とに沿って配置される。したがって、膨張式救命胴衣４０のカバー部材６０の両端部は、右肩ベルト部１４と左肩ベルト部１５との間隔だけ離れた状態で配置される。このため、膨張式救命胴衣４０によってハーネス型安全帯１０の胸ベルト及び胸ベルト用連結具２８、２９が覆われることがなく、膨張式救命胴衣４０を固定したハーネス型安全帯１０を着用者１が容易に脱着することができる。すなわち、図９に示すように、両端部が互いに固定された従来周知の膨張式救命胴衣１４０を用いる場合、膨張式救命胴衣１４０によってハーネス型安全帯１０の胸ベルト及び胸ベルト用連結具２８、２９が覆われてしまい、ハーネス型安全帯１０の脱着が煩雑になる。また、従来周知の膨張式救命胴衣１４０をハーネス型安全帯１０に固定しない場合、ハーネス型安全帯１０の胸ベルトとは別に、救命胴衣用腰ベルト７０を適切な長さで装着しなくてはならず、着用者１は、膨張式救命胴衣１４０の脱着及びハーネス型安全帯１０の脱着が煩雑になる。   Then, by attaching the lower right attachment portion 64 to the right shoulder belt portion 14 and attaching the lower left attachment portion 66 to the left shoulder belt portion 15, the inflatable life jacket 40 is attached to the right shoulder belt portion 14, the left shoulder belt portion 15, It is arranged along. Therefore, both end portions of the cover member 60 of the inflatable life jacket 40 are arranged at a distance from the right shoulder belt portion 14 to the left shoulder belt portion 15. For this reason, the inflatable life jacket 40 does not cover the chest belt of the harness type safety belt 10 and the coupling devices 28 and 29 for the chest belt, and the wearer 1 wears the harness type safety belt 10 to which the inflatable life jacket 40 is fixed. Can be easily detached. That is, as shown in FIG. 9, when using a conventionally well-known inflatable life jacket 140 having both ends fixed to each other, the inflatable life jacket 140 uses the chest belt and the chest belt connector 28 of the harness type safety belt 10, 29 is covered, and attaching and detaching the harness type safety belt 10 becomes complicated. In addition, when the conventionally known inflatable life jacket 140 is not fixed to the harness-type safety belt 10, the waist belt 70 for the life jacket must be worn at an appropriate length separately from the chest belt of the harness-type safety belt 10. In other words, the wearer 1 has trouble in attaching and detaching the inflatable life jacket 140 and attaching and detaching the harness-type safety belt 10.

本実施形態では、膨張式救命胴衣４０は、ハーネス型安全帯１０の右肩ベルト部１４及び左肩ベルト部１５に沿って固定されるため、ハーネス型安全帯１０の胸ベルト及び胸ベルト用連結具２８、２９が膨張式救命胴衣４０によって覆われることがなく、膨張式救命胴衣４０を固定したハーネス型安全帯１０を着用者１が容易に脱着することができる。また、ハーネス型安全帯１０を着用者１が脱着するだけで、同時に膨張式救命胴衣４０も脱着することが可能なため、脱着を容易にして作業性を向上することができる。   In the present embodiment, since the inflatable life jacket 40 is fixed along the right shoulder belt portion 14 and the left shoulder belt portion 15 of the harness type safety belt 10, the chest belt of the harness type safety belt 10 and the coupling for the chest belt are provided. 28 and 29 are not covered with the inflatable life jacket 40, and the wearer 1 can easily attach and detach the harness-type safety belt 10 to which the inflatable life jacket 40 is fixed. In addition, the inflatable life jacket 40 can be simultaneously attached and detached only by the wearer 1 attaching and detaching the harness type safety belt 10, so that attachment and detachment can be facilitated and workability can be improved.

そして、本実施形態では、膨張式救命胴衣４０の両端部を右肩ベルト部１４及び左肩ベルト部１５に固定することで、膨張式救命胴衣４０のカバー部材６０の両端部が離れた位置に配置されていても、本実施形態では、気室部材５０は、両端部において外側が右胸固定部９０及び左胸固定部９１によってカバー部材６０に固定されているため、気室部材５０の気室５１内に気体を充填した際に、気室部材５０の両端部をカバー部材６０に固定された右胸固定部９０及び左胸固定部９１よりも内側に膨張させることができる。したがって、気室部材５０の右胸部５２と左胸部５３とを着用者１の中心線に向かって膨張させて、右胸部５２と左胸部５３との内面同士を当接させると共に当接させた状態を維持することができ、気室部材５０にＶ字形状の空間を形成して、着用者１の顎下に気室部材５０を配置して、着用者１の顎下の浮力を確保することができる。したがって、着用者１の浮遊姿勢を後傾として、口元を水面から離すことができ、安全性を向上することができる。ちなみに、気室部材５０の両端部においてその内側をカバー部材６０に固定してしまうと、本実施形態のように、カバー部材６０の両端部を右肩ベルト部１４及び左肩ベルト部１５に固定した場合には、気室部材５０が膨張した際に右胸部５２と左胸部５３とが着用者１の中心線から外側に向かって膨張し、着用者１の顎下に気室部材５０が配置されずに着用者１の顎下の浮力を確保することができない。このため、着用者１を正しい姿勢で浮かすことができず、口元が水面と近くなり、安全性が低下してしまう。   In this embodiment, by fixing both ends of the inflatable life jacket 40 to the right shoulder belt portion 14 and the left shoulder belt portion 15, the both end portions of the cover member 60 of the inflatable life jacket 40 are arranged at positions away from each other. In this embodiment, the air chamber member 50 is fixed to the cover member 60 at both ends by the right and left chest fixing portions 90 and 91 in the present embodiment. When the gas is filled in the inside 51, both ends of the air chamber member 50 can be inflated more inside than the right chest fixing part 90 and the left chest fixing part 91 fixed to the cover member 60. Accordingly, the right chest 52 and the left chest 53 of the air chamber member 50 are inflated toward the center line of the wearer 1 so that the inner surfaces of the right chest 52 and the left chest 53 are in contact with each other and in contact with each other. Can be maintained, and a V-shaped space is formed in the air chamber member 50, and the air chamber member 50 is arranged under the chin of the wearer 1 to secure buoyancy under the chin of the wearer 1. Can be. Therefore, the mouth can be separated from the water surface with the floating posture of the wearer 1 inclined backward, and safety can be improved. By the way, when the inside of the air chamber member 50 is fixed to the cover member 60 at both ends, the both ends of the cover member 60 are fixed to the right shoulder belt portion 14 and the left shoulder belt portion 15 as in the present embodiment. In this case, when the air chamber member 50 expands, the right chest 52 and the left chest 53 expand outward from the center line of the wearer 1, and the air chamber member 50 is arranged under the chin of the wearer 1. Buoyancy below the chin of the wearer 1 cannot be ensured. For this reason, the wearer 1 cannot be floated in a correct posture, the mouth becomes close to the water surface, and safety is reduced.

また、膨張式救命胴衣４０は、ハーネス型安全帯１０に右上部取付部６３、右下部取付部６４、左上部取付部６５、左下部取付部６６によって着脱可能としたため、ハーネス型安全帯１０を単体でも利用することができる。したがって単体のハーネス型安全帯１０と膨張式救命胴衣４０が固定されたハーネス型安全帯１０との両方を用意する必要がなく、コストを低減することができる。   In addition, the inflatable life jacket 40 is detachable from the harness-type safety belt 10 by the upper right mounting portion 63, the lower right mounting portion 64, the upper left mounting portion 65, and the lower left mounting portion 66. It can be used alone. Therefore, it is not necessary to prepare both a single harness-type safety band 10 and a harness-type safety band 10 to which the inflatable life jacket 40 is fixed, and the cost can be reduced.

以上説明したように、本実施形態の着脱可能な膨張式救命胴衣４０を備えたハーネス型安全帯１０では、右肩ベルト部１４と左肩ベルト部１５と右腿ベルト部１９と左腿ベルト部２３と右肩ベルト部１４に一端が固定された右胸ベルト２６と左肩ベルト部１５に一端が固定された左胸ベルト２７と右胸ベルト２６と左胸ベルト２７とのそれぞれに設けられて、互いに着脱可能に設けられた連結具である胸ベルト用連結具２８、２９と、を具備するハーネス型安全帯１０と、逆Ｕ字形状を有し、着用者１の首の後ろから両胸に掛けて着用する膨張式救命胴衣４０であって、ハーネス型安全帯１０に着脱可能に設けられた膨張式救命胴衣４０と、を具備し、膨張式救命胴衣４０は、気体が充填されることで膨らむ気室部材５０と、気室部材５０の気室５１に気体が充填されていない状態で当該気室部材５０を内部に保持するカバー部材６０と、を具備し、カバー部材６０は、右肩ベルト部１４及び左肩ベルト部１５に沿って着脱可能に固定されており、カバー部材６０は、気室部材５０の気室５１内に気体が充填されて膨らむことで開き、気室部材５０の両端部のそれぞれは、幅方向の外側がカバー部材６０に固定され、気室部材５０の気室５１内に気体が充填されて膨張した際に、当該気室部材５０は、カバー部材６０との固定部分である右胸固定部９０及び左胸固定部９１よりも内側に向かって膨張する。   As described above, in the harness-type safety belt 10 including the detachable inflatable life jacket 40 according to the present embodiment, the right shoulder belt portion 14, the left shoulder belt portion 15, the right thigh belt portion 19, and the left thigh belt portion 23 are provided.

The inflatable life jacket according to the second embodiment described above was worn by a wearer alone and the waist belt for the life jacket was maximized as Example 8.

（試験例）
上述した実施例１〜８の気室部材の気室内に気体を充填して膨張させた状態で浮遊性能として着用者の水面の垂線方向に対する角度と、水面から口元までの距離とを測定した。この結果を下記表１に示す。なお、着用者の体重は７０ｋｇであり、膨張式救命胴衣の基準の浮力は約１７ｋｇである。また、着用者の浮遊角度は、着用者を撮影して角度を測定したものであり、プラス（＋）が後傾を表し、マイナス（−）が前傾を表している。 (Test example)
In the state where the air chambers of the air chamber members of Examples 1 to 8 were filled with gas and inflated, the angle with respect to the perpendicular direction of the water surface of the wearer and the distance from the water surface to the mouth were measured as floating performance. The results are shown in Table 1 below. The weight of the wearer is 70 kg, and the standard buoyancy of the inflatable life jacket is about 17 kg. The floating angle of the wearer is obtained by photographing the wearer and measuring the angle. A plus (+) indicates a backward inclination, and a minus (-) indicates a forward inclination.

表１に示すように、実施例１〜８の何れの場合であっても、着用者１の浮遊姿勢が前傾ではなく後傾となり、且つ口元の水面からの距離を０ｃｍ以上とすることができる。   As shown in Table 1, in any case of Examples 1 to 8, the floating posture of the wearer 1 becomes not the forward tilt but the backward tilt, and the distance from the water surface of the mouth to 0 cm or more. it can.

特に、実施例１の膨張式救命胴衣を固定したハーネス型安全帯を装着した着用者の浮遊角度が＋５５度と最も大きな角度とすることができ、口元の水面からの距離を１２ｃｍと最も離すことができたため、膨張式救命胴衣の気室部材が着用者の顎下に配置され、着用者の顎を気室部材が確実に浮かしていることが分かる。つまり、実施例３のハーネス型安全帯を用いずに、膨張式救命胴衣を単体で使用した場合よりも、実施例１の膨張式救命胴衣をハーネス型安全帯に装着した場合の方が、浮遊姿勢及び口元の水面からの距離が優れていることが分かった。実施形態５の場合も同様に、実施例７のハーネス型安全帯を用いずに、膨張式救命胴衣を単体で使用した場合よりも、実施例５の膨張式救命胴衣をハーネス型安全帯に装着した場合の方が、浮遊姿勢及び口元の水面からの距離も優れていることが分かった。   In particular, the floating angle of the wearer wearing the harness-type safety belt to which the inflatable life jacket of Example 1 is fixed can be set to the largest angle of +55 degrees, and the distance from the water surface at the mouth to the maximum of 12 cm. Thus, it can be seen that the air chamber member of the inflatable life jacket is arranged under the chin of the wearer, and the air chamber member surely floats the chin of the wearer. That is, when the inflatable life jacket of the first embodiment is attached to the harness type safety belt, the floating state is better than when the inflatable life jacket is used alone without using the harness type safety belt of the third embodiment. It was found that the posture and the distance of the mouth from the water surface were excellent. Similarly, in the case of the fifth embodiment, the inflatable life jacket of the fifth embodiment is attached to the harness-type safety belt as compared with the case where the inflatable life jacket is used alone without using the harness-type safety belt of the seventh embodiment. It was also found that the case in which the floating posture and the distance from the water surface at the mouth were better.

また、実施例１の膨張式救命胴衣を固定したハーネス型安全帯を着用した着用者の浮遊角度が＋５５度であったのに対し、実施例２の膨張式救命胴衣の右下部取付部及び左下部取付部をハーネス型安全帯の右肩ベルト部及び左肩ベルト部の胸ベルトよりも上方に固定した場合の＋３５度よりも大きな角度となることが分かった。これは、実施例１では、膨張式救命胴衣の右下部取付部及び左下部取付部がハーネス型安全帯の胸ベルトよりも下側に固定されていると、右下部取付部及び左下部取付部が胸ベルトによって上方への移動が規制され、膨張式救命胴衣がハーネス型安全帯の背ベルトを引っ張る形になるため、着用者の体全体が浮き上がるような形となるからである。これに対して、実施例２では、右下部取付部及び左下部取付部が肩ベルト上を上方に移動し、結果として膨張式救命胴衣がハーネス型安全帯よりも上方に浮き上がってしまい、膨張式救命胴衣が着用者の首だけを保持するような形になるため、浮力姿勢が垂直に近づいてしまう。このため、実施例１のように、膨張式救命胴衣の右下部取付部及び左下部取付部がハーネス型安全帯の胸ベルトよりも下側に固定するなど、膨張式救命胴衣の右下部取付部及び左下部取付部が、ハーネス型安全帯の肩ベルトを上方に移動しないように固定することで、着用者の安定した浮力姿勢を確保することができる。   In addition, the floating angle of the wearer wearing the harness-type safety belt to which the inflatable life jacket of Example 1 was fixed was +55 degrees, whereas the lower right attachment part and the lower left of the inflatable life jacket of Example 2 were +55 degrees. It was found that the angle was larger than +35 degrees when the part mounting part was fixed above the chest belt of the right shoulder belt part and the left shoulder belt part of the harness type safety belt. In the first embodiment, when the lower right mounting portion and the lower left mounting portion of the inflatable life jacket are fixed below the chest belt of the harness type safety belt, the lower right mounting portion and the lower left mounting portion are provided. This is because the upward movement is restricted by the chest belt, and the inflatable life jacket pulls the back belt of the harness-type safety belt, so that the entire body of the wearer rises. On the other hand, in the second embodiment, the lower right mounting portion and the lower left mounting portion move upward on the shoulder belt, and as a result, the inflatable life jacket floats above the harness type safety belt, and the inflatable Since the life vest has a shape that holds only the wearer's neck, the buoyancy posture approaches vertical. For this reason, as in the first embodiment, the lower right mounting portion and the lower left mounting portion of the inflatable life jacket are fixed below the chest belt of the harness type safety belt. The lower left attachment portion fixes the shoulder belt of the harness-type safety belt so as not to move upward, so that a stable buoyancy posture of the wearer can be secured.

また、実施例４では、着用者の浮遊角度が最も小さい＋１０度となり、口元の水面からの距離も最も低い３ｃｍとなっており、実施例８では、浮遊角度は＋３０度であるものの口元の水面からの距離が４ｃｍと低くなっているため、救命胴衣用腰ベルトの調整の必要性を確認できた。   In the fourth embodiment, the floating angle of the wearer is +10 degrees, which is the smallest, and the distance from the water surface at the mouth is also 3 cm, which is the smallest. In the eighth embodiment, the floating angle is +30 degrees, but the water surface at the mouth is Since the distance from the camera was as low as 4 cm, the necessity of adjusting the waist belt for life jackets was confirmed.
