Description

本発明は、水難事故における水難者の安全を確保するために用いられるライフジャケットに関する。   The present invention relates to a life jacket used for ensuring the safety of a water refugee in a water accident.

海、湖沼あるいは河川における水難事故において、漁船やレジャーボートなどの船舶から落下した水難者の安全を確保するために、ライフジャケット(救命胴衣)の着用が推奨されている。
このようなライフジャケットとしては、従来より、不活性ガスを封入したボンベと、該ボンベの開栓時に導入される不活性ガスにより膨張する膨縮可能な帯状の膨張性浮袋と、該膨張性浮袋を収縮させて帯状に折り畳んだ状態で外方から面ファスナにより綴じて上記ボンベと共に収納する収納カバーと、上記ボンベ、上記膨張性浮袋及び上記収納カバーを身体に拘束する拘束ベルトと、を備えたものが知られている(例えば、特許文献1参照)。上記ライフジャケットでは、着水時の水との接触による自動操作又は水難者自身による手動操作によりボンベが開栓し、このボンベの開栓時に導入される不活性ガスにより上記膨張性浮袋を膨張させる。そして、上記面ファスナのフック状に起毛されたフック側部位とループ状に密集して起毛されたループ側部位とを、上記膨張性浮袋の膨張に合わせて積極的に分離させることにより、上記収納カバーの内部から上記膨張性浮袋をスムーズに展開させて浮力を生じさせるようにしている。
Life jackets (life jackets) are recommended to ensure the safety of water victims who have fallen from vessels such as fishing boats and leisure boats in the event of a water disaster in the sea, lakes or rivers.
As such a life jacket, conventionally, a cylinder filled with an inert gas, an inflatable and inflatable inflatable bag that expands by an inert gas introduced when the cylinder is opened, and the inflatable bag A storage cover that is bound by a surface fastener from the outside in a state of being folded into a belt shape and stored together with the cylinder, and a restraint belt that restrains the cylinder, the inflatable bladder, and the storage cover to the body. Those are known (for example, see Patent Document 1). In the life jacket, the cylinder is opened by automatic operation by contact with water at the time of landing or by manual operation by the water refugee himself, and the inflatable bladder is inflated by an inert gas introduced when the cylinder is opened. . Then, the hook side portion raised like a hook of the hook-and-loop fastener and the loop side portion raised close together in a loop shape are actively separated according to the expansion of the inflatable floating bag, thereby The inflatable bladder is smoothly deployed from the inside of the cover to generate buoyancy.

特開2003−200886号公報JP 2003-200906 A

ところで、上記ライフジャケットでは、ボンベの開栓時に膨張性浮袋の膨張に合わせて面ファスナが積極的に分離して収納カバーの内部から膨張性浮袋がスムーズに展開できるものの、上記面ファスナは、その構造上、フック側部位とループ側部位とにゴミなどが付着し易いものであった。その場合、面ファスナは、定期的に付着したゴミを除去する必要があるが、帯状の収納カバーのほぼ全域に亘って設けられたものであるため、ゴミの除去作業が非常に煩わしいものとなる。
かかる点から、面ファスナは、ゴミの除去作業がほとんど行われることがなく、フック側部位とループ側部位とにそれぞれ付着したゴミによって接着力が経時的に低下して互いに分離し易いものとなり、ボンベの閉栓時であるにも関わらず膨張性浮袋を収納カバーの内部に拘束しておくには無理がある。
しかも、面ファスナのフック側部位とループ側部位とにそれぞれ付着したゴミによって見栄えが悪化するといった問題もある。
By the way, in the life jacket, although the hook-and-loop fastener is positively separated in accordance with the expansion of the inflatable floating bag when the cylinder is opened, the inflatable floating bag can be smoothly deployed from the inside of the storage cover. Due to the structure, dust or the like easily adheres to the hook side portion and the loop side portion. In that case, it is necessary to remove dust adhered regularly, but the surface fastener is provided over almost the entire area of the belt-like storage cover, so that the dust removal operation becomes very troublesome. .
From this point, the surface fastener is hardly subjected to dust removal work, and the adhesive force decreases with time due to dust attached to the hook side portion and the loop side portion, respectively, and is easily separated from each other. Although the cylinder is closed, it is impossible to restrain the inflatable bag inside the storage cover.
In addition, there is a problem that the appearance deteriorates due to dust attached to the hook side portion and the loop side portion of the hook and loop fastener.

そこで、上記面ファスナに代えて、樹脂製のエレメントがテープに射出成型された、所謂“ビスロン”ファスナなど(以下、単にファスナという)を用いることが考えられる。このものでは、ボンベの閉栓時における膨張性浮袋の拘束が確実に行える上、ゴミなどが付着し難いものとなって見栄えが良好に確保される。   Therefore, it is conceivable to use a so-called “vislon” fastener (hereinafter simply referred to as a fastener) in which a resin element is injection-molded on a tape instead of the surface fastener. In this case, it is possible to reliably restrain the inflatable floating bag when the cylinder is closed, and it is difficult to attach dust and the like, so that a good appearance is secured.

しかしながら、このようなファスナでは、エレメント同士のかみ合いが強いため、ボンベの開栓時に膨張性浮袋が膨張してもエレメント同士が分離し難く、膨張性浮袋をスムーズに展開することができないおそれがある。   However, in such a fastener, since the engagement between the elements is strong, even if the inflatable bladder expands when the cylinder is opened, the elements are difficult to separate from each other, and the inflatable bladder may not be deployed smoothly. .

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、膨張性浮袋をエレメント同士のかみ合いが強いファスナにより綴じて収納カバーの内部に収納していても、ボンベの開栓時に膨張性浮袋を確実に展開させることができるライフジャケットを提供することにある。   The present invention has been made in view of the above points, and an object of the present invention is to open the cylinder even when the inflatable float is bound and stored in the storage cover by a fastener having strong engagement between elements. An object of the present invention is to provide a life jacket capable of reliably deploying an inflatable float when plugged.

上記目的を達成するため、本発明では、ライフジャケットとして、不活性ガスを封入したボンベと、上記ボンベの開栓時に当該ボンベから導入される不活性ガスにより膨張する膨縮可能な帯状の膨張性浮袋と、上記膨張性浮袋を収縮させて帯状に折り畳んだ状態で外方からファスナにより綴じて上記ボンベと共に収納する収納カバーと、上記ボンベ、上記膨張性浮袋及び上記収納カバーを身体に拘束する拘束ベルトと、を備える。そして、上記ファスナに、上記ボンベの開栓時に上記膨張性浮袋の膨張に合わせて上記ファスナのエレメント同士のかみ合い部分を積極的に分離させる分離起点部を設けている。
この特定事項により、ボンベの開栓時に膨張性浮袋が膨張すると、その膨張性浮袋の膨張に合わせてファスナの分離起点部が起点となって当該ファスナのエレメント同士のかみ合い部分の分離が円滑に行われる。これにより、ボンベの開栓時に膨張性浮袋を確実に展開させることが可能となる。
In order to achieve the above object, in the present invention, as a life jacket, a cylinder filled with an inert gas, and an expandable / contractable strip-like expansibility that is expanded by the inert gas introduced from the cylinder when the cylinder is opened. A bag, a storage cover that is folded by a fastener from the outside in a state in which the inflatable bag is contracted and folded into a belt shape, and is stored together with the cylinder, and a constraint that restrains the cylinder, the inflatable bag, and the storage cover to the body A belt. The fastener is provided with a separation starting point portion that positively separates the engaging portions of the fastener elements in accordance with the expansion of the inflatable bladder when the cylinder is opened.
Due to this specific matter, when the inflatable bladder is inflated when the cylinder is opened, the fastener separation starting point is the starting point in accordance with the expansion of the inflatable bladder, and the meshed portions of the fastener elements are smoothly separated. Is called. This makes it possible to reliably expand the inflatable bladder when the cylinder is opened.

また、上記分離起点部が、上記ボンベの開栓により不活性ガスが導入される上記膨張性浮袋の導入口付近に対応する上記ファスナの対応部位に設けられるものであることが好ましい。これによれば、ボンベからの不活性ガスの導入口付近において膨張し始める膨張性浮袋の膨張に合わせてファスナのエレメント同士のかみ合い部分が効果的に分離し、ボンベの開栓時に膨張性浮袋を効率よく展開させることができる。   In addition, it is preferable that the separation starting point portion is provided at a corresponding portion of the fastener corresponding to the vicinity of the inlet of the inflatable floating bag into which the inert gas is introduced by opening the cylinder. According to this, the engaging portion of the fastener elements is effectively separated in accordance with the expansion of the inflatable floating bag that starts to expand in the vicinity of the inert gas inlet from the cylinder, and the inflatable floating bag is formed when the cylinder is opened. Can be deployed efficiently.

更に、上記分離起点部に、上記ボンベの閉栓時に上記ファスナのエレメント同士のかみ合い部分を分離不能に拘束する拘束手段を設け、この拘束手段が、上記ボンベの開栓時に上記膨張性浮袋の膨張に合わせて上記ファスナのエレメント同士のかみ合い部分の拘束を解除するものであることが好ましい。
この場合には、エレメント同士のかみ合い部分が分離し易いファスナの分離起点部が拘束手段によって拘束されているので、ファスナのエレメント同士のかみ合い部分がボンベの閉栓時に不用意に分離することがなく、膨張性浮袋を収納カバーの内部に円滑に拘束しておくことができる。一方、ボンベの開栓時に膨張性浮袋が膨張し始めると、その膨張に合わせて、拘束手段による膨張性浮袋の拘束が解除されるので、ファスナのエレメント同士のかみ合い部分が効果的に分離し、膨張性浮袋をスムーズに展開させることができる。
Further, the separation starting point is provided with a restraining means for restraining the meshing portion of the fastener elements so as not to be separable when the cylinder is closed, and this restraining means is used for expanding the inflatable floating bag when the cylinder is opened. In addition, it is preferable to release the restraint of the meshing portion between the fastener elements.
In this case, since the separation starting point portion of the fastener that is easy to separate the meshing portion between the elements is restrained by the restraining means, the meshing portion between the elements of the fastener is not inadvertently separated when the cylinder is closed, The inflatable float can be smoothly restrained inside the storage cover. On the other hand, when the inflatable bladder begins to expand when the cylinder is opened, the restraint of the inflatable bladder is released by the restraining means in accordance with the expansion, so that the meshing portions of the fastener elements are effectively separated, The inflatable bladder can be smoothly deployed.

以上、要するに、ボンベの開栓時に膨張性浮袋の膨張に合わせてエレメント同士のかみ合い部分を積極的に分離させる分離起点部をファスナに設けることで、膨張性浮袋の膨張に合わせてファスナの分離起点部を起点とするエレメント同士のかみ合い部分の分離が円滑に行われ、ボンベの開栓時に膨張性浮袋を確実に展開させることができる。   In short, by providing the fastener with a separation starting point that positively separates the meshing portions of the elements in accordance with the expansion of the inflatable bladder when the cylinder is opened, the fastener separation starting point in accordance with the expansion of the inflatable bladder Separation of the meshing portion between elements starting from the portion is performed smoothly, and the inflatable bladder can be reliably deployed when the cylinder is opened.

The stopper of the cylinder 11 is forcibly opened when the wearer of the life jacket 1 pulls the string 24 with the right hand.

そして、図3に示すように、上記ファスナ15には、上記ボンベ11の開栓時に上記膨張性浮袋12の膨張に合わせて上記ファスナ15のエレメント15a,15a同士のかみ合い部分を積極的に分離させる分離起点部16が設けられている。この分離起点部16でのファスナ15のエレメント15a,15aの形状は、スライダ15bによってエレメント15a,15a同士をかみ合わせても互いに引っ掛かり合わずに直ぐに分離する形状に変更されている。また、図4に示すように、ボンベ11及び開栓機構2は、膨張性浮袋12の一方の端部(図4では左側の端部)付近に設けられたポケット状の保持部12aに保持されている。そして、上記分離起点部16は、上記ボンベ11の開栓により不活性ガスが導入される上記膨張性浮袋12の導入口付近に対応する上記ファスナ15の対応部位つまり上記保持部12aの近傍に位置している。   Then, as shown in FIG. 3, the fastener 15 positively separates the engagement portion between the elements 15 a and 15 a of the fastener 15 in accordance with the expansion of the inflatable bladder 12 when the cylinder 11 is opened. A separation starting point portion 16 is provided. The shape of the elements 15a and 15a of the fastener 15 at the separation starting point portion 16 is changed to a shape in which the elements 15a and 15a are immediately separated without being caught even when the elements 15a and 15a are engaged with each other by the slider 15b. As shown in FIG. 4, the cylinder 11 and the opening mechanism 2 are held by a pocket-like holding portion 12 a provided near one end portion (left end portion in FIG. 4) of the inflatable bladder 12. ing. The separation starting point portion 16 is located in a corresponding portion of the fastener 15 corresponding to the vicinity of the inlet of the inflatable bladder 12 into which the inert gas is introduced by opening the cylinder 11, that is, in the vicinity of the holding portion 12 a. is doing.

更に、上記分離起点部16には、上記ボンベ11の閉栓時に上記ファスナ15のエレメント15a,15a同士のかみ合い部分を分離不能に拘束する拘束手段17が設けられている。この拘束手段17は、一方のエレメント15a側(図3では左側)に一辺が取り付けられた略矩形状の拘束片17aと、他方のエレメント15a側(図3では右側)に取り付けられた面ファスナ18のフック状に起毛するフック側部位18aと、このフック側部位18aに対応する拘束片17aの他辺に取り付けられた面ファスナ18のループ状に密集して起毛するループ側部位18bとからなる。そして、上記ボンベ11の閉栓時には、面ファスナ18のフック側部位18aとループ側部位18bとの接着力で他辺側に引っ張られた拘束片17aにより、上記分離起点部16でのファスナ15のエレメント15a,15a同士のかみ合い部分を互いに引き寄せ合って分離不能な状態に拘束する。一方、上記ボンベ11の開栓時には上記膨張性浮袋12の膨張に合わせて面ファスナ18のフック側部位18aとループ側部位18bとが分離し、上記分離起点部16でのファスナ15のエレメント15a,15a同士のかみ合い部分の分離不能な状態での拘束を解除する。   Further, the separation starting point portion 16 is provided with a restraining means 17 for restraining the engaging portion between the elements 15a, 15a of the fastener 15 so as not to be separated when the cylinder 11 is closed. The restraining means 17 includes a substantially rectangular restraint piece 17a having one side attached to one element 15a side (left side in FIG. 3), and a hook and loop fastener 18 attached to the other element 15a side (right side in FIG. 3). The hook side portion 18a is raised in a hook shape, and the loop side portion 18b is raised in a loop shape of the surface fastener 18 attached to the other side of the restraining piece 17a corresponding to the hook side portion 18a. When the cylinder 11 is closed, the element of the fastener 15 at the separation starting point 16 is caused by the restraining piece 17a pulled to the other side by the adhesive force between the hook side portion 18a and the loop side portion 18b of the surface fastener 18. The meshing portions 15a and 15a are attracted to each other and restrained in an inseparable state. On the other hand, when the cylinder 11 is opened, the hook-side portion 18a and the loop-side portion 18b of the hook-and-loop fastener 18 are separated in accordance with the expansion of the inflatable bladder 12, and the elements 15a and 15a of the fastener 15 at the separation starting portion 16 are separated. The restraint in the state in which the meshing portions of 15a cannot be separated is released.

したがって、上記実施の形態では、ボンベ11の開栓時に膨張性浮袋12が膨張すると、その膨張性浮袋12の膨張に合わせて面ファスナ18のフック側部位18aとループ側部位18bとが分離し、分離起点部16でのファスナ15のエレメント15a,15a同士のかみ合い部分の拘束が解除される。これにより、ファスナ15の分離起点部16が起点となって当該ファスナ15のエレメント15a,15a同士のかみ合い部分の分離が円滑に行われ、ボンベ11の開栓時に膨張性浮袋12を確実に展開させることができる。   Therefore, in the above embodiment, when the inflatable bladder 12 is inflated when the cylinder 11 is opened, the hook side portion 18a and the loop side portion 18b of the hook and loop fastener 18 are separated in accordance with the expansion of the inflatable bladder 12. The restraint of the meshing portion between the elements 15a, 15a of the fastener 15 at the separation starting point portion 16 is released. As a result, the separation starting point 16 of the fastener 15 is the starting point, and the meshing portion between the elements 15a, 15a of the fastener 15 is smoothly separated, and the inflatable bladder 12 is reliably deployed when the cylinder 11 is opened. be able to.

また、上記分離起点部16が、上記ボンベ11の開栓により不活性ガスが導入される膨張性浮袋12の導入口付近に対応するファスナ15の対応部位つまり保持部12aの近傍に位置している。これにより、ボンベ11からの不活性ガスの導入口付近において膨張し始める膨張性浮袋12の膨張に合わせてファスナ15のエレメント15a,15a同士のかみ合い部分が効果的に分離し、ボンベ11の開栓時に膨張性浮袋12をスムーズに展開させる上で非常に有利なものとなる。   Further, the separation starting point portion 16 is located in a corresponding portion of the fastener 15 corresponding to the vicinity of the introduction port of the inflatable bladder 12 into which the inert gas is introduced by opening the cylinder 11, that is, in the vicinity of the holding portion 12a. . As a result, the meshing portions of the elements 15a and 15a of the fastener 15 are effectively separated in accordance with the expansion of the inflatable bladder 12 that starts to expand in the vicinity of the inert gas inlet from the cylinder 11, and the cylinder 11 is opened. This is sometimes very advantageous for smoothly expanding the inflatable bladder 12.

更に、上記ボンベ11の閉栓時には面ファスナ18のフック側部位18aとループ側部位18bとの接着力で引っ張られた拘束片17aにより、上記分離起点部16でのファスナ15のエレメント15a,15a同士のかみ合い部分を互いに引き寄せ合って分離不能な状態に拘束している。これにより、ファスナ15のエレメント15a,15a同士のかみ合い部分がボンベ11の閉栓時に不用意に分離することがなく、膨張性浮袋12を収納カバー13の内部に円滑に拘束しておくことができる。   Further, when the cylinder 11 is closed, the elements 15a and 15a of the fastener 15 at the separation starting point 16 are connected to each other by the restraining piece 17a pulled by the adhesive force between the hook side portion 18a and the loop side portion 18b of the surface fastener 18. The meshing portions are attracted to each other and restrained in an inseparable state. Thereby, the engaging part of the elements 15a, 15a of the fastener 15 is not inadvertently separated when the cylinder 11 is closed, and the inflatable bladder 12 can be smoothly restrained inside the storage cover 13.

また、面ファスナ18は、拘束片17aの他辺を接着するだけの短いもので済むので、フック側部位18aとループ側部位18bとに付着したゴミの除去も簡単に行え、ゴミの付着による面ファスナ18の経時的な接着力の低下を抑制して、ボンベ11の閉栓時に分離起点部16を確実に拘束することができる上、ゴミによる面ファスナ18の見栄えの悪化も抑制できる。   Further, since the hook and loop fastener 18 is short enough to bond the other side of the restraining piece 17a, it is possible to easily remove the dust adhered to the hook side portion 18a and the loop side portion 18b. It is possible to suppress the deterioration of the adhesive force of the fastener 18 over time, and to reliably restrain the separation starting point portion 16 when the cylinder 11 is closed, and to suppress the deterioration of the appearance of the surface fastener 18 due to dust.

本発明は、上記実施の形態に限定されるものではなく、その他種々の変形例を包含している。例えば、上記実施の形態では、首に掛けて装着する帯状タイプのライフジャケット1について述べたが、図5〜図8に示すように、腰の周りに巻いて装着する帯状タイプのライフジャケット3であってもよい。このライフジャケット3は、膨張性浮袋12を収縮させた状態で帯状に折り畳んで外方からファスナ15により綴じてボンベ11と共に収納する収納カバー13と、上記ボンベ11、上記膨張性浮袋12及び上記収納カバー13を身体の腰周りに拘束する拘束ベルト14とを備える。また、上記ボンベ11及び開栓機構2を保持する保持部12aが、上記膨張性浮袋12の長手方向略中央部(身体に装着した状態では背中の略中央部)付近に設けられている。更に、上記ファスナ15の分離起点部16は、上記ボンベ11の開栓により不活性ガスが導入される上記膨張性浮袋12の導入口付近に対応する上記ファスナ15の対応部位つまり保持部12aの近傍に位置している。この分離起点部16にも拘束手段17が設けられ、この拘束手段17は、一方のエレメント15a側(図6では下側)に一辺が取り付けられた略矩形状の拘束片17aと、他方のエレメント15a側(図6では上側)に拘束片17aの他辺を接着する面ファスナ18とからなる。また、図7及び図8に示すように、膨張性浮袋12の長手方向一端には他端を連結する係合ベルト31の一端が取り付けられ、この係合ベルト31によってボンベ11開栓時に膨張した膨張性浮袋12の両端を連結している。この変形例においても、上記実施の形態と同様の作用効果が得られる。   The present invention is not limited to the above-described embodiment, and includes various other modifications. For example, in the above-described embodiment, the band-type life jacket 1 that is worn around the neck is described. However, as shown in FIGS. There may be.
