夏はプールや海でのレジャーを楽しむ人が多く、エアマットレスは水に浮かべ て楽しみを増す他、海難時の救出用にも使えるという効果を有している。しかし 、従来のエアマットレスは以下のような欠点を有していた。 （イ）空気を充填する必要があり、先に空気を充填した場合は体積が増加して 携帯に不便であり、目的地に着いてから充填する時間と体力も無駄であった。 （ロ）水遊び中に不慮の事故が発生した場合、空気を充填してからでなければ 救出用に使用できなかった。 （ハ）固定充気式のもの、すなわち最初から空気を充填して密閉したものでは 体積が大きく携帯に不便であった。 （ニ）水上での使用以外の用途を持たなかった。 （ホ）水中で破損しやすく、空気漏れにより事故が発生する危険があった。 In summer, many people enjoy leisure at the pool or at the sea, and the air mattress has the effect of being floated on the water to increase fun and also used for rescue in the event of a marine disaster. However, the conventional air mattress has the following drawbacks. (B) It is necessary to fill with air, and if it is filled with air first, the volume will increase and it will be inconvenient to carry, and the time and physical strength to fill it after reaching the destination will be wasted. (B) If an unexpected accident occurred while playing in the water, the air could only be filled before it could be used for rescue. (C) The fixed air-filled type, that is, the type that was filled with air and sealed from the beginning, had a large volume and was inconvenient to carry. (D) It had no use other than use on water. (E) It was easily damaged in water and there was a risk of accidents due to air leaks.
【０００３】[0003]
本考案の課題は以下の通りである。 （イ）第１に、エアマットレスの内部にポリエチレン製の蜂の巣状構造を設け 、高い浮力と安全性を得ること。 （ロ）第２に、エアマットレスに通気穴を設け、空気を自然に内部層に充填で き、浮力と安全性を高めること。 （ハ）第３に、ベルト通しと調整ベルトを設けて環状とし、一般の救命用浮輪 としても使用できること。 （ニ）第４に、スライドファスナーと持ち手を設け、折り畳んでバッグとする ことができること。 （ホ）第５に、適度な撓み性と柔軟性を有し、折り畳んで収納や携帯に便利で あること。 （ヘ）第６に、構造が簡単で、製造および使用が簡単であること。 The problems of the present invention are as follows. (A) First, a polyethylene honeycomb structure is provided inside the air mattress to obtain high buoyancy and safety. (B) Secondly, air holes are provided in the air mattress so that air can be naturally filled in the inner layer, which improves buoyancy and safety. (C) Thirdly, a belt loop and an adjustment belt should be provided to form a ring, which can also be used as a general lifesaving float. (D) Fourth, it should be possible to fold it into a bag by providing slide fasteners and handles.

本考案の外観は偏平な矩形を呈する、図２に示されるように、その外層は、１ 層の防水性の下防水層（１）と１層の上防水層（２）から成り、これら２層に挟 まれた部分に複数のポリエチレン製の蜂の巣状構造（３）（４）（５）（６）を 設けている。さらに下防水層（１）とその上の蜂の巣状構造（３）を貫通する複 数の通気穴（１１）を設ける。また蜂の巣状構造（３）（４）（５）（６）をＳ 型縫合線（１２）により互いに縫合する。上防水層（２）上には一列の並列する 複数のベルト通し（２１）を設け、図２に示されるように、下防水層（１）と蜂 の巣状構造（３）は貼合され、各蜂の巣状構造（４）（５）（６）と上防水層（ ２）も貼合される。これら二組の貼合する部分の間には間隙があり、全体の外縁 は縫合によりへり（７）を設ける。 The appearance of the present invention presents a flat rectangle, as shown in FIG. 2, the outer layer is composed of one waterproof lower waterproof layer (1) and one upper waterproof layer (2). A plurality of polyethylene honeycomb structures (3), (4), (5) and (6) are provided in the portion sandwiched between the layers. Furthermore, a plurality of ventilation holes (11) are provided to penetrate the lower waterproof layer (1) and the honeycomb structure (3) above it. Further, the honeycomb structures (3), (4), (5) and (6) are sewn to each other by the S-type suture line (12). A plurality of belt loops (21) arranged in parallel are provided on the upper waterproof layer (2), and the lower waterproof layer (1) and the honeycomb structure (3) are bonded together as shown in FIG. The honeycomb structure (4) (5) (6) and the upper waterproof layer (2) are also laminated. There is a gap between these two sets of bonded parts, and the outer edge of the whole is provided with a hem (7) by stitching.
【０００５】[0005]
図１と図３の本考案の充気時の状態を示す断面図を参照する。図３に示される ように、使用者が下防水層（１）と蜂の巣状構造（３）からなる下層と上防水層 （２）と蜂の巣状構造（４）（５）（６）からなる上層を引き離すとき、外部空 気は通気穴（１１）から自然に両層構造間に進入する。すなわち外部のポンプ等 を使用しなくても充気状態を形成する。これを水上に浮かべると、水面の密閉作 用で空気が漏れない。 Please refer to FIG. 1 and FIG. 3 which are sectional views showing the state of the present invention when inflated. As shown in FIG. 3, the user has a lower layer composed of a lower waterproof layer (1) and a honeycomb structure (3), and an upper layer composed of an upper waterproof layer (2) and a honeycomb structure (4) (5) (6). When the air is separated, the external air naturally enters between the two layer structures through the ventilation hole (11). In other words, the filled state is formed without using an external pump or the like. If this is floated on the water, air will not leak due to the closed surface operation.
【０００６】 さらに、図１に示される各層間のＳ型縫合線（２２）により空気が進入したと きの蓄積作用を生じ、浮力をさらに高める。これらＳ型縫合線（２２）による固 定は空気の流通を阻み、Ｓ型縫合線（２２）で隔てられた部分の中間に適当な数 の充気穴を設けた後、上防水層（２）を下防水層（１）と結合して不透水性のへ り（７）を設けたことで、空気漏れがなく浮力を維持する。Furthermore, the S-shaped suture line (22) between the layers shown in FIG. 1 causes an accumulation action when air enters, further enhancing buoyancy. The fixation with these S-type suture lines (22) blocks the flow of air, and after providing an appropriate number of air holes in the middle of the part separated by the S-type suture lines (22), the upper waterproof layer (2 ) Is combined with the lower waterproof layer (1) to provide a water impermeable rim (7), so that buoyancy is maintained without air leakage.

まず、本考案の第１実施例であるが、図１に示される本考案の平面図、側面図 、底面図と図２の上記図１Ａ−Ａにおける断面図を参照する。図１に示されるよ うに、本考案の外観は偏平な矩形を呈する、図２に示されるように、その外層は 、１層の防水性の下防水層（１）と１層の上防水層（２）から成り、これら２層 に挟まれた部分に複数のポリエチレン製の蜂の巣状構造（３）（４）（５）（６ ）を設けている。さらに下防水層（１）とその上の蜂の巣状構造（３）を貫通す る複数の通気穴（１１）を設ける。また蜂の巣状構造（３）（４）（５）（６） はＳ型縫合線（１２）により互いに縫合される。上防水層（２）上には並列に複 数のベルト通し（２１）を設け、図２に示されるように、下防水層（１）と蜂の 巣状構造（３）は貼合され、各蜂の巣状構造（４）（５）（６）と上防水層（２ ）も貼合される。二組の貼合する部分の間には間隙があるが、外縁は図１に示さ れるように縫合し、へり（７）を設けている。 First, the first embodiment of the present invention will be described with reference to the plan view, side view and bottom view of the present invention shown in FIG. 1 and the sectional view of FIG. 1A-A of FIG. As shown in FIG. 1, the appearance of the present invention is a flat rectangle. As shown in FIG. 2, its outer layer is one waterproof lower waterproof layer (1) and one upper waterproof layer. A plurality of polyethylene honeycomb structures (3), (4), (5) and (6) are provided in the part sandwiched between these two layers. Furthermore, a plurality of ventilation holes (11) are provided to penetrate the lower waterproof layer (1) and the honeycomb structure (3) above it. The honeycomb structures (3), (4), (5) and (6) are sewn together by the S-shaped suture line (12).

Although there is a gap between the two sets of bonded parts, the outer edge is sewn as shown in FIG. 1 and has a lip (7).
【０００８】 本考案は、体重（Ｗ）＝人体体積（Ｖ）×人体密度（Ｄ）および水中における 人体が必要な支え力＝体重−浮力で示されるアルキメデスの原理に基づき考案さ れたものであり、９０ｋｇの人を例にとり、必要な支え力を産出すると、 支え力＝人体密度×人体体積−水密度×人体体積 ＝１．０７×人体体積−１×人体体積 ＝（１．０７−１）×人体体積 ＝０．０７（体重／人体密度） ＝０．０７（９０／１．０７） ＝５．８８８ｋｇ となり、９０ｋｇの人は水中においてわずか５．８８８ｋｇの浮力を必要とする ことがわかる。同様に、 １００ｋｇの人では６．５４２ｋｇの浮力 ８０ｋｇの人では５．２３３ｋｇの浮力 ７０ｋｇの人では４．５７９ｋｇの浮力 ６０ｋｇの人では３．９２５ｋｇの浮力 ５０ｋｇの人では３．２７１ｋｇの浮力 ４０ｋｇの人では２．６１７ｋｇの浮力 ３０ｋｇの人では１．９３３ｋｇの浮力 をそれぞれ必要とする。 本考案者は、図２に示される実施例の製品を日本船舶品質管理協会に提出し、 浮力試験を受けた結果、この製品は１３．７ｋｇの浮力を有し、体重１００ｋｇ の人が上に乗っても十分にゆとりがある。また本考案は、ポリエチレン製の蜂の 巣状構造の層を増加することによりさらに浮力を高めることができる。The present invention was devised based on Archimedes' principle, which is represented by weight (W) = human body volume (V) × human body density (D) and supporting force required by human body in water = weight−buoyancy. Yes, taking a 90 kg person as an example, when the required supporting force is produced, supporting force = human body density × human body volume−water density × human body volume = 1.07 × human body volume−1 × human body volume = (1.07-1 ) × human body volume = 0.07 (body weight / human body density) = 0.07 (90 / 1.07) = 5.888 kg, which shows that a 90 kg person needs only 5.888 kg of buoyancy in water. . Similarly, a 100 kg person has a buoyancy of 6.542 kg, a person with 80 kg has a buoyancy of 5.233 kg, a person with 70 kg has a buoyancy of 4.579 kg, a person with 60 kg has a buoyancy of 3.925 kg, and a person with 50 kg has a buoyancy of 3271 kg, a weight of 40 kg. A person needs a buoyancy of 2.617 kg and a person of 30 kg needs a buoyancy of 1.933 kg. The present inventor submitted the product of the embodiment shown in FIG. 2 to the Japan Ship Quality Control Association, and as a result of the buoyancy test, the product has a buoyancy of 13.7 kg and a person who weighs 100 kg is on top. There is ample room for riding. In addition, the present invention can further enhance buoyancy by increasing the number of layers of the honeycomb structure made of polyethylene.
