【発明の属する技術分野】
本発明は、空気膨張式の救命具に関する。
【０００２】
【従来の技術】
岩場等で釣りを行う場合、従来、釣人は救命具としてジャケットの上に、ポリ塩化ビニール独立発泡材やＥＶＡ独立発泡材を浮力材としたフローティングベストを着用していたが、昨今、浮力材による嵩張りをなくし、人が落水した場合に水分を感知してボンベが自動的にまたは作動紐を引く等の手動で作動して、カバー内に収納された空気袋を膨張させる所謂空気膨張式の救命具（ライフジャケット）が広く普及しつつある（例えば、下記の非特許文献１参照。）。
【０００３】
このライフジャケットは、正面視逆Ｕ字状に形成されたカバー体と、当該カバー体内に膨出可能に折り畳まれて収納された空気袋と、当該カバー体の両片先端側の裏面に止着された胴ベルトと、当該胴ベルトとカバー体との間に架け渡された背面ベルトとで構成されており、カバー体を首（ジャケットの衿）にかけ、そして、カバー体の両片をジャケットの左右の前身頃に沿わせて、胴ベルトに装着した左右のバックルをウエスト部分の正面で係合して着用するようになっている。
【０００４】
また、カバー体内には、既述したように落水時の水分を感知して空気袋を膨張させるボンベ（空気充填装置）が取り付けられている。

【０００５】
【発明が解決しようとする課題】
而して、上述した空気膨張式の救命具は、予め折り畳まれた空気袋をカバー体内に収納した構造上、固形状の浮力材を用いたフローティングベストに比し着用時に大きく嵩張ることはないものの、落水後、ボンベが自動的に作動して空気袋が膨張するまでに５秒程度の時間がかかるため、その間の人の沈みを防止することができず、また、落水による動揺もあって空気袋が本当に膨張するかどうか不安を感じる虞もあった。
【０００６】
また、カバー体は天然材料の布・やナイロン，塩化ビニルの合成樹脂製シート等で形成され、空気袋はナイロンや塩化ビニル，エチレン酢酸ビニル等の合成樹脂を材料として形成されているため、実釣時に釣針がカバー体に引っ掛からないようにする気遣いが必要であった。
本発明は斯かる実情に鑑み案出されたもので、上述した空気膨張式の救命具に改良を加え、空気袋に空気が注入，充填されるまでの間、最低限の浮力を確保し、併せて空気袋の耐針性を上げて耐久性の向上を図った救命具を提供することを目的とする。
【０００７】
【課題を解決するための手段】
斯かる目的を達成するため、請求項１に係る発明は、正面視逆Ｕ字状に形成され、装着用ベルトが止着されたカバー体と、当該カバー体内に、外部へ膨出可能に収納された空気袋と、カバー体内に装着され、当該空気袋に空気を充填する空気充填装置とを備えた救命具に於て、上記カバー体の内面に沿って空気袋とカバー体との間に、発泡材からなる浮力体を装着したことを特徴とする。
【０００８】
そして、請求項２に係る発明は、請求項１記載の救命具に於て、カバー体と浮力体との間に補強シートを介在させたものである。
【０００９】
（作用）
請求項１に係る発明によれば、カバー体の内面に沿って空気袋とカバー体との間に発泡材からなる浮力体が装着されているため、実釣時に釣針がカバー体に引っ掛かっても、浮力体の厚みによって針先が空気袋にまで達して孔を開けることがない。
【００１０】
また、釣人が誤って落水した場合、水の浸入で空気充填装置が作動してカバー体内で空気袋が膨張し、空気袋がカバー体から外部に大きく膨出して落水した釣人を水面に浮かせることとなるが、救命具は浮力体によって最低限の浮力が確保されているため、落水後、空気充填装置が作動して空気袋が膨張するまでの間、浮力体の浮力で沈下速度が遅くなって釣人が沈むことがない。
【００１１】
そして、請求項２に係る発明によれば、実釣時に釣針がカバー体に引っ掛かっても、補強シートによって釣針の貫通が防止され、また、浮力体の厚みで針先が空気袋にまで達することがない。
【００１２】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて詳細に説明する。
【００１３】
図１乃至図５は請求項１及び請求項２の一実施形態に係る空気膨張式の救命具を示し、図に於て、１は天然材料の布・やナイロン，塩化ビニル等の合成樹脂シートで形成されたカバー体で、図２に示すようにカバー体１は、内周側が連なったカバー前方部３とカバー後方部５を扁平な断面Ｃ字状に折り曲げて図１の如き正面視逆Ｕ字状に形成され、首（衿）に掛けるための湾曲部とその両側から垂下する一対の片部を有する形状となっている。そして、カバー前方部３とカバー後方部５の外周側同士は面ファスナ７で着脱自在に止着され、更にカバー前方部３とカバー後方部５の逆Ｕ字の夫々の先端３１，３３側は、周縁に沿って縫い付けられて止着されている。
【００１４】
尚、既述した布・や合成樹脂シートからカバー前方部３とカバー後方部５を別体に裁断して、夫々の内周側と先端側を縫着することでカバー体を形成してもよい。
そして、図１乃至図５に示すようにカバー体１内に、後述するように当該カバー体１から外部に正面視逆Ｕ字状に膨出可能に形成された空気袋９が、カバー体１の形状に沿って折り畳まれて収納されており、斯様に折り畳まれた状態の空気袋９は浮力を有していない。
【００１５】
図２に示すように空気袋９は、ナイロンや塩化ビニル，ポリウレタン，エチレン酢酸ビニル等の気密性が高く耐針性の大きい一枚の合成樹脂シートの裁断部１３，１５を接合して、正面視逆Ｕ字状に膨張可能に形成されている。そして、空気袋９はその接合部１７が、後述する浮力体１９や補強シート２１と共に、カバー体１の内周側に糸２３で止着されている。
【００１６】
更に、図１に示すようにカバー体１の右片２５内には、空気袋９を膨張させる１本のボンベ２７が胴ベルト２９の止着部位より上方に収納されており、このボンベ２７は従来周知のボンベと同一構造で、人が落水した場合に、カバー体１内に浸入した水分を感知して自動的に空気袋９に空気を注入，充填する。
而して、斯様にボンベ２７が作動してカバー体１内で空気袋９が膨張すると、面ファスナ７によるカバー前方部３とカバー後方部５との止着が解除されて、空気袋９が図５の如くカバー体１の外周側から外部に正面視逆Ｕ字状に大きく膨出するようになっている。そして、斯様に膨出した空気袋９は浮力を有する状態となる。
【００１７】
また、図１に示すようにカバー体１の両片先端３１，３３の表面側に、バックル３５を有する胴ベルト２９が縫い付けられて止着されており、カバー体１の両片先端３１，３３はこの胴ベルト２９により身体に押圧されて、当該両片先端３１，３３と身体との間への釣糸の入り込みが防止されている。
而も、カバー体１の両片先端３１，３３側は、胴ベルト２９に覆われて下方に突出しないように構成されているため、併せて釣糸の引っ掛かりも防止できるようになっている。そして、既述したように、胴ベルト２９によって空気袋９の膨張を妨げることがないように、空気袋９は胴ベルト２９の止着部位より上方のカバー体１内に収納されている。
【００１８】
そして、本実施形態に係る救命具３７は、上述した構成に加え、空気袋９に空気が注入，充填されるまでの間に最低限の浮力を確保し、併せて空気袋９の耐針性を上げて耐久性の向上を図るため、カバー体１内に浮力体１９と補強シート２１を装着したことを特徴とする。
浮力体１９は、胴ベルト２９の止着部分と面ファスナ７が取り付く外周縁を除くカバー体１の内面形状に合わせて裁断された１枚のポリ塩化ビニルウレタンやエチレン酢酸ビニル等の合成樹脂やクロロプレンゴム等の発泡材（独立気泡発泡材）で形成され、１ｋｇ以上の浮力を有している。そして、図２に示すように浮力体１９は、扁平な断面Ｃ字状に折り曲げられたカバー体１の内面全体に沿って空気袋９との間に装着されて、空気袋９と共にカバー体１の内周側に糸２３で止着されている。
【００１９】
尚、この浮力体１９は、救命具３７に最低限の浮力を確保し、併せて実釣時にカバー体１に引っ掛かった釣針の針先がカバー体１から空気袋９にまで達することがないように２．０ｍｍ以上の厚みとすることが好ましい。但し、浮力体１９はあくまで空気袋９が膨張するまでに必要な最低限の浮力を確保するためのものであるから、独立発泡材等の浮力材のみを用いた従来のフローティングベストの如き量の発泡材は必要ない。
【００２０】
このため、従来のフローティングベストと異なり、救命具３７は着用時（空気袋９の非膨張時）に嵩張ることがない。
そして、上記浮力体１９とカバー体１との間に、更なる耐針性を確保する目的で、ナイロン等の合成樹脂シートやケプラーからなる織物シートを用いて浮力体１９と同一形状に裁断された補強シート２１が介在されており、図２に示すようにこの補強シート２１も、空気袋９，浮力体１９と共にカバー体１の内周側に糸２３で一カ所止着されている。そして、補強シート２１はカバー体１より高密度に形成されて、より大きな耐針性を有している。
【００２１】
尚、上述したように本実施形態は、浮力体１９と補強シート２１をカバー体１の内周側に糸２３で一カ所止着したが、補強シート２１の全面をカバー体１の内面に接着剤等で貼着し、また、浮力体１９の全面を補強シート２１に接着剤等で貼着してもよい。更にカバー体１を表面と裏面を有するように形成して、両面間に浮力体１９や補強シート２１を介在させてもよい。
【００２２】
加えて、最低限の浮力を確保できるのであれば、浮力体１９は少なくともカバー前方部３の内面に装着されていればよいし、実釣時に釣針がカバー後方部５に引っ掛かることはないため、カバー前方部３の内面にのみ補強シート２１を装着してもよい。
また、浮力体１９をカバー体１のカバー前方部３に貼着することなく設ければ、浮力体１９がカバー体１とは別に独立して動くため、カバー体１を釣針が通ってしまっても、浮力体１９が釣針の針先の方向に対し刺さらない方向に逃げるように動いて釣針の刺さりを防止できる。
【００２３】
更に、補強シート２１がカバー前方部３に貼着されていないと、これと同様に釣針が補強シート２１に刺さり難くなる。
そして、図１及び図４に示すようにカバー体１の両片先端３１，３３の内側には、互いに係合可能な一対のファスナ３９，４１が止着されており、両ファスナ３９，４１を互いに係合することで救命具３７を恰も首に巻き付けるように着用できるが、両ファスナ３９，４１は、釣人が着用するジャケット（図示せず）の左右の前身頃に止着されたファスナにも係合できるようになっている。
【００２４】
上記ファスナ３９，４１は救命具３７の胴体回り方向へのズレを防止するために止着されたもので、斯様にファスナ３９，４１をジャケット側のファスナに係合することで、キャスティングの際に救命具３７全体が胴体回りにズレてしまうことがないようになっている。
そして、胴ベルト２９とカバー体１の上部背面側との間に背面ベルト４３が架け渡されて、本実施形態に係る救命具３７が形成されており、胴ベルト２９と背面ベルト４３は、例えば木綿や天然皮革の天然材料、または、ナイロン，塩化ビニル等の合成樹脂で形成されている。
【００２５】
本実施形態はこのように構成されているから、ジャケットを着た釣人は、救命具３７をジャケットの衿にかけ、そして、これをジャケットの左右の前身頃に沿わせてファスナ３９，４１をジャケット側のファスナに係合させた後、胴ベルト２９のバックル３５をウエスト部分の正面で係合すれば、ジャケットの上に救命具３７が着用される。
【００２６】
そして、カバー体１の両片先端３１，３３は胴ベルト２９により身体に押圧されているため、当該両片先端３１，３３と身体との間に釣糸が入り込むことがなく、また、両片先端３１，３３側は胴ベルト２９に覆われて下方に突出しないように構成されているため、釣糸が両片先端３１，３３側に絡まることもない。
また、空気袋９は浮力体１９と補強シート２１で覆われて保護されているため、実釣時に釣針がカバー体１に引っ掛かっても、補強シート２１によって釣針の貫通が防止され、仮に針先が補強シートを貫通しても、浮力体１９の厚みによって針先が空気袋９にまで達して孔を開けることがない。
【００２７】
更にまた、救命具３７のファスナ３９，４１をジャケット側のファスナに係合させたことで、キャスティングの際に救命具３７の胴体回り方向へのズレが防止されることとなる。
そして、釣人が誤って落水した場合、水の浸入でボンベ２７が自動的に作動してカバー体１内で空気袋９が膨張し、この結果、図５の如く面ファスナ７によるカバー前方部３とカバー後方部５との止着が解除されて、空気袋９がカバー体１の外周側から外部に正面視逆Ｕ字状に大きく膨出して落水した釣人を水面に浮かせることとなるが、既述したように空気袋９は胴ベルト２９の止着部位より上方のカバー体１内に収納されているため、胴ベルト２９によって空気袋９の膨張が妨げられることがない。
【００２８】
また、既述したように救命具３７は浮力体１９によって最低限の浮力が確保されているため、落水後、ボンベ２７が自動的に作動して空気袋９が膨張するまでの間、浮力体１９の浮力で沈下速度が遅くなって釣人が沈むことがない。
このように本実施形態は、浮力体１９によって落水時の最低限の浮力を確保し、併せて空気袋９を保護する浮力体１９と補強シート２１をカバー体１内に装着して空気袋９の耐針性を確保したので、落水後、ボンベ２７によって空気袋９に空気が注入，充填されるまでの間、浮力体１９の浮力で沈下速度が遅くなって釣人が水中に沈むことがないため、釣人に不安を与えることがなくなり、また、実釣時に釣針がカバー体１に引っ掛かっても、針先が空気袋９にまで達して空気袋９に孔を開けてしまう虞もなくなった。
【００２９】
尚、既述したように、従来、ボンベを用いたこの種の空気膨張式の救命具には、万が一、ボンベが作動せずに空気袋が膨張しない場合に作動紐を引っ張ってボンベを作動させる構造のものがあるが、本発明は斯かる救命具にも適用可能である。
また、浮力体１９を構成する発泡材は、屈曲性を出すために一枚だけでなく積層構造も可能である。
【００３０】
【発明の効果】
以上述べたように、請求項１に係る発明によれば、浮力体によって最低限の浮力を確保し、併せて当該浮力体で空気袋を保護して空気袋の耐針性を確保したので、落水後、空気充填装置によって空気袋に空気が注入，充填されるまでの間、浮力体の浮力で沈下速度が遅くなって釣人が水中に沈むことがないため、釣人に不安を与えず、また、実釣時に釣針がカバー体に引っ掛かっても、針先がカバー体から空気袋に達して空気袋に孔を開けてしまうこともなくなった。
【００３１】
そして、請求項２に係る発明によれば、補強シートで更に空気袋を保護したので、空気袋のより優れた耐針性を確保することが可能となって、救命具の耐久性を更に向上させることができる利点を有する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an inflatable life-saving device.
[0002]
[Prior art]
Conventionally, when fishing on rocky places, anglers have worn floating vests made of PVC independent foam or EVA independent foam on the jacket as a life-saving device. A so-called air-inflatable life-saving device that removes tension and senses moisture when a person falls, and automatically activates the cylinder or manually operates such as pulling an operating cord to inflate the air bag stored in the cover. (Life jacket) is becoming widespread (for example, see Non-Patent Document 1 below).
[0003]
The life jacket includes a cover body formed in an inverted U-shape in a front view, an air bag folded and stored so as to be swellable in the cover body, and fixed to a back surface of both ends of the cover body. And a back belt stretched between the torso belt and the cover body. The cover body is hung on the neck (collar of the jacket), and both pieces of the cover body are attached to the jacket. The left and right buckles attached to the torso belt are worn in front of the waist along the left and right front bodies.
[0004]
Further, as described above, a cylinder (air filling device) that senses moisture at the time of falling and inflates the air bag is attached to the cover body.
[Non-patent document 1]
Published by Daiwa Seiko Co., Ltd., 2002 Daiwa Fishing Supplies General Catalog, 157 pages, 158 pages, 165 pages
[Problems to be solved by the invention]
Thus, although the above-described air-inflatable lifesaving device has a structure in which a pre-folded air bag is stored in the cover body, it does not have a large bulk when worn compared to a floating vest using a solid buoyant material. After the water falls, it takes about 5 seconds for the cylinder to automatically operate and the air bag to inflate. Therefore, it is not possible to prevent the sinking of people during that time. I was worried that I would really expand.
[0006]
The cover body is made of natural material cloth or a sheet made of synthetic resin such as nylon and vinyl chloride. The air bag is made of synthetic resin such as nylon, vinyl chloride and ethylene vinyl acetate. Care was required to prevent the hook from catching on the cover when fishing.
The present invention has been devised in view of such circumstances, and improves the above-described inflatable life-saving device to secure a minimum buoyancy until air is filled and filled in the air bag. It is an object of the present invention to provide a life-saving device in which the needle resistance of an air bag is increased to improve durability.
[0007]
[Means for Solving the Problems]
In order to achieve such an object, the invention according to claim 1 is formed in an inverted U-shape when viewed from the front, and a cover body to which a mounting belt is fixed, and is housed in the cover body so as to be swellable to the outside. In the lifesaving device provided with the air bag and the air filling device mounted in the cover body and filling the air bag with air, between the air bag and the cover body along the inner surface of the cover body, A buoyant body made of a foam material is attached.
[0008]
According to a second aspect of the invention, in the lifesaving device of the first aspect, a reinforcing sheet is interposed between the cover body and the buoyant body.
[0009]
(Action)
According to the first aspect of the present invention, since the buoyant body made of a foam material is mounted between the air bag and the cover body along the inner surface of the cover body, even if the hook is hooked on the cover body during actual fishing. In addition, the needle tip does not reach the air bag due to the thickness of the buoyant body, and does not make a hole.
[0010]
Also, if the angler accidentally falls, the air filling device operates due to the infiltration of water, the air bag expands inside the cover, and the air bag greatly swells out of the cover to the outside, causing the angler to fall and float on the water surface. However, since the life-saving device has the minimum buoyancy by the buoyancy body, the sinking speed is slowed down by the buoyancy of the buoyancy body after the water falls, until the air filling device operates and the air bag inflates. The angler never sinks.
[0011]
According to the invention of claim 2, even when the hook is hooked on the cover body during actual fishing, the penetration of the hook is prevented by the reinforcing sheet, and the tip of the hook reaches the air bag due to the thickness of the buoyant body. There is no.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0013]
1 to 5 show an air-inflatable rescue device according to an embodiment of the present invention. In the drawings, reference numeral 1 denotes a cloth made of a natural material or a synthetic resin sheet such as nylon or vinyl chloride. As shown in FIG. 2, the cover body 1 is formed by bending a cover front part 3 and a cover rear part 5, whose inner peripheral sides are continuous, into a flat C-shaped cross section, as shown in FIG. 1. It is formed in a character shape and has a shape having a curved portion for hanging on a neck (collar) and a pair of pieces hanging down from both sides thereof. The outer peripheral sides of the cover front part 3 and the cover rear part 5 are detachably fastened with a hook-and-loop fastener 7, and the front ends 31, 33 of the inverted front U of the cover front part 3 and the cover rear part 5 are connected to each other. , Sewn along the periphery and fastened.
[0014]
In addition, the cover body may be formed by cutting the cover front part 3 and the cover rear part 5 separately from the cloth or the synthetic resin sheet described above, and sewing the inner peripheral side and the distal end side thereof. Good.
As shown in FIGS. 1 to 5, an air bag 9 formed in the cover body 1 so as to be swellable in an inverted U-shape in front view from the cover body 1 to the outside as described later is provided in the cover body 1. The air bag 9 in the folded state does not have buoyancy.
[0015]
As shown in FIG. 2, the air bag 9 is formed by joining cut portions 13 and 15 of one synthetic resin sheet having high airtightness and high needle resistance such as nylon, vinyl chloride, polyurethane, ethylene vinyl acetate, etc. It is formed so as to be expandable in a U-shape when viewed from the opposite side. The joint portion 17 of the air bag 9 is fixed to the inner peripheral side of the cover body 1 with a thread 23 together with a buoyant body 19 and a reinforcing sheet 21 described later.
[0016]
Further, as shown in FIG. 1, one cylinder 27 for inflating the air bag 9 is accommodated in the right piece 25 of the cover body 1 above a fastening portion of the trunk belt 29, and this cylinder 27 is It has the same structure as a conventional well-known cylinder, and when water falls, senses the moisture that has entered the cover body 1 and automatically injects and fills the air bag 9 with air.
Thus, when the cylinder 27 is operated and the air bag 9 is inflated in the cover body 1, the fastening of the cover front portion 3 and the cover rear portion 5 by the hook-and-loop fastener 7 is released, and the air bag 9 is opened. However, as shown in FIG. 5, the cover body 1 bulges outward from the outer peripheral side in an inverted U-shape when viewed from the front. Then, the inflated air bag 9 becomes buoyant.
[0017]
Further, as shown in FIG. 1, a torso belt 29 having a buckle 35 is sewn and fastened to the surface side of both ends 31 and 33 of the cover body 1 so that the two ends 31 and 33 of the cover body 1 are fixed. 33 is pressed against the body by the torso belt 29 to prevent the fishing line from entering between the two ends 31 and 33 and the body.
Since both ends 31 and 33 of the cover body 1 are covered with the torso belt 29 so as not to protrude downward, the catch of the fishing line can be prevented at the same time. As described above, the air bag 9 is housed in the cover body 1 above the fastening portion of the body belt 29 so as not to hinder the inflation of the air bag 9 by the body belt 29.
[0018]
The lifesaving device 37 according to the present embodiment, in addition to the above-described configuration, secures a minimum buoyancy between the time the air is injected into the air bag 9 and the time the air is filled, and the needle bag resistance of the air bag 9 as well. The buoyancy body 19 and the reinforcing sheet 21 are mounted in the cover body 1 in order to improve the durability by raising.
The buoyancy member 19 is made of one piece of synthetic resin such as polyvinyl chloride urethane or ethylene vinyl acetate cut in accordance with the inner surface shape of the cover body 1 excluding the fastening portion of the trunk belt 29 and the outer peripheral edge to which the hook-and-loop fastener 7 is attached. It is made of a foaming material (closed-cell foaming material) such as chloroprene rubber and has a buoyancy of 1 kg or more. Then, as shown in FIG. 2, the buoyancy body 19 is mounted between the cover body 1 and the air bag 9 along the entire inner surface of the cover body 1 bent into a flat C-shaped cross section. Is fixed with a thread 23 on the inner peripheral side.
[0019]
The buoyancy body 19 secures a minimum buoyancy to the lifesaving device 37, and also ensures that the tip of the hook hooked on the cover body 1 during actual fishing does not reach the air bag 9 from the cover body 1. Preferably, the thickness is 2.0 mm or more. However, since the buoyancy body 19 is only for securing the minimum buoyancy required until the air bag 9 is inflated, the buoyancy body 19 has the same amount as a conventional floating vest using only a buoyancy material such as an independent foam material. No foam is required.
[0020]
Therefore, unlike the conventional floating vest, the lifesaving device 37 does not become bulky when worn (when the air bag 9 is not inflated).
Then, between the buoyant body 19 and the cover body 1, in order to secure further needle resistance, it is cut into the same shape as the buoyant body 19 using a synthetic resin sheet such as nylon or a woven sheet made of Kepler. As shown in FIG. 2, the reinforcing sheet 21 is also fixed to the inner peripheral side of the cover 1 together with the air bag 9 and the buoyant body 19 with a thread 23 at one place. The reinforcing sheet 21 is formed at a higher density than the cover body 1 and has greater needle resistance.
[0021]
As described above, in this embodiment, the buoyant body 19 and the reinforcing sheet 21 are fixed at one place on the inner peripheral side of the cover body 1 with the thread 23, but the entire surface of the reinforcing sheet 21 is adhered to the inner surface of the cover body 1. Alternatively, the entire surface of the buoyant body 19 may be attached to the reinforcing sheet 21 with an adhesive or the like. Further, the cover 1 may be formed to have a front surface and a back surface, and the buoyancy body 19 and the reinforcing sheet 21 may be interposed between both surfaces.
[0022]
In addition, as long as the minimum buoyancy can be ensured, the buoyancy body 19 only needs to be attached to at least the inner surface of the cover front part 3, and the fishing hook does not catch on the cover rear part 5 during actual fishing. The reinforcing sheet 21 may be attached only to the inner surface of the front part 3 of the cover.
Further, if the buoyancy body 19 is provided without being attached to the cover front portion 3 of the cover body 1, the buoyancy body 19 moves independently of the cover body 1, so that the fishing hook passes through the cover body 1. Also, the buoyant body 19 moves so as to escape in a direction not sticking with respect to the direction of the tip of the hook, so that sticking of the hook can be prevented.
[0023]
Furthermore, if the reinforcing sheet 21 is not stuck to the front part 3 of the cover, similarly, it becomes difficult for the hooks to stick into the reinforcing sheet 21.
As shown in FIGS. 1 and 4, a pair of fasteners 39, 41 that can be engaged with each other are fastened to the inside of both ends 31, 33 of the cover body 1. By engaging with each other, the life-saving device 37 can be worn as if it were wrapped around the neck. However, both fasteners 39 and 41 are also related to fasteners fastened to the left and right front bodies of a jacket (not shown) worn by the angler. Can be combined.
[0024]
The fasteners 39 and 41 are fixed in order to prevent the life-saving device 37 from shifting in the direction around the body, and by engaging the fasteners 39 and 41 with the fasteners on the jacket side during casting, The whole rescuer 37 does not shift around the body.
Then, a back belt 43 is bridged between the trunk belt 29 and the upper rear side of the cover body 1 to form the lifesaving device 37 according to the present embodiment. The trunk belt 29 and the back belt 43 are made of, for example, cotton. And natural materials of natural leather or synthetic resin such as nylon and vinyl chloride.
[0025]
Since the present embodiment is configured as described above, the angler wearing the jacket puts on the collar of the jacket with the rescuer 37, and places the fasteners 39, 41 on the jacket side along the left and right front bodies of the jacket. After engaging with the fastener, if the buckle 35 of the torso belt 29 is engaged in front of the waist portion, the lifesaving device 37 is worn on the jacket.
[0026]
Since both ends 31 and 33 of the cover 1 are pressed against the body by the torso belt 29, the fishing line does not enter between the two ends 31 and 33 and the body. Since the sides 31 and 33 are configured to be covered with the body belt 29 so as not to protrude downward, the fishing line does not become entangled with the ends 31 and 33 of the two pieces.
Further, since the air bag 9 is covered and protected by the buoyant body 19 and the reinforcing sheet 21, even if the hook is hooked on the cover body 1 during actual fishing, the penetration of the fishing hook is prevented by the reinforcing sheet 21 and the tip of the hook is temporarily provided. Even when the needle penetrates the reinforcing sheet, the needle tip does not reach the air bag 9 due to the thickness of the buoyant body 19 and does not make a hole.
[0027]
Furthermore, by engaging the fasteners 39 and 41 of the lifesaving device 37 with the fastener on the jacket side, the displacement of the lifesaving device 37 in the direction around the body during casting is prevented.
If the angler accidentally drops the water, the cylinder 27 is automatically activated by the infiltration of the water, and the air bag 9 is inflated in the cover body 1. As a result, as shown in FIG. The air bag 9 is released from the outer peripheral side of the cover body 1 to the outside in a substantially inverted U-shape when viewed from the front, and the fisher who has fallen and floats on the water surface. As described above, since the air bag 9 is accommodated in the cover body 1 above the fastening position of the trunk belt 29, the inflating of the air bag 9 is not hindered by the trunk belt 29.
[0028]
Further, as described above, since the life-saving device 37 has a minimum buoyancy by the buoyancy member 19, the buoyancy member 19 is automatically operated after the water is dropped and the air bag 9 is inflated until the cylinder 27 is inflated. The sinking speed is slowed by the buoyancy of the fisherman, and the angler does not sink.
As described above, according to the present embodiment, the buoyancy body 19 secures the minimum buoyancy at the time of water drop, and the buoyancy body 19 for protecting the air bag 9 and the reinforcing sheet 21 are mounted in the cover body 1 to form the air bag 9. , The sinking speed is reduced by the buoyancy of the buoyancy body 19 until the air is injected into the air bag 9 by the cylinder 27 and filled with the gas after the water is dropped, so that the angler does not sink in the water. Therefore, there is no fear that the angler will be given anxiety, and even if the hook is hooked on the cover body 1 during actual fishing, there is no danger that the tip of the hook will reach the air bag 9 and make a hole in the air bag 9.
[0029]
As described above, a conventional air-inflatable rescue device of this type using a cylinder has a structure in which an operating cord is pulled to operate the cylinder in the event that the air bag does not inflate without the cylinder operating. However, the present invention is also applicable to such a lifesaving device.
Further, the foamed material constituting the buoyant body 19 may have not only one sheet but also a laminated structure in order to exhibit flexibility.
[0030]
【The invention's effect】
As described above, according to the first aspect of the invention, the minimum buoyancy is secured by the buoyant body, and the air bag is protected by the buoyant body and the needle resistance of the air bag is secured. After dropping water, the buoyancy of the buoyancy body slows down the sinking speed and prevents the angler from sinking in the water until the air is injected and filled into the air bag by the air filling device. Even when the hook is hooked on the cover body during actual fishing, the tip of the hook does not reach the air bag from the cover body and a hole is opened in the air bag.
[0031]
According to the second aspect of the present invention, since the air bag is further protected by the reinforcing sheet, it is possible to secure more excellent needle resistance of the air bag and further improve the durability of the lifesaving device. Can have the advantage.
