【考案の詳細な説明】 この考案は主として幼児や水泳初心者の児童が着用する
のに好適な水泳練習用浮袋に関する。[Detailed Description of the Invention] This invention relates to a swim bladder for swimming practice which is suitable to be worn mainly by infants and children who are beginners in swimming.

水泳練習用の浮袋は単に浮力を附加しただけでは水泳に
伴う浮力の会得が困難である。It is difficult to acquire the buoyancy associated with swimming by simply adding buoyancy to a swim bladder for swimming practice.

すなわち、浮袋の装着に際しては、単に使用者の浮力を
補うだけでなく、使用者の身体と一体的に密着し、全身
の動きを拘束せず、かつ浮袋自体による水流抵抗等を発
生しないことが理想であり、この点からすると、例えば
身体に巻装する救命胴衣や大径の浮輪等では水泳練習具
として不適当である。In other words, when wearing a swim bladder, it is important not only to supplement the user's buoyancy, but also to ensure that it is in close contact with the user's body, does not restrict the movement of the entire body, and does not create water flow resistance due to the swim bladder itself. This is an ideal, but from this point of view, for example, life vests that are wrapped around the body, large diameter floats, etc. are inappropriate as swimming practice equipment.

このため、例えば空気袋を利用した背嚢形浮袋（実公昭
５−９４８１号公報）やスチロール材やカポック綿を浮
材として利用した浮き具（実公昭３６−２４０９３号公
報、実公昭３８−１１５６７号公報）が提案されている
が、前者では空気袋自体が身体から別個に浮上して安定
性を損う不利や、口金からの空気漏れや袋の破れ等によ
る浮力喪失の危険があり、後者においては浮き具を腹部
や胸部に捲きつけたり、胸部に当接しているので遊泳中
に身体の安定を悪くし、又四肢の運動が妨げられる等の
欠点があり、特に幼児や初心の児童用水泳練習具として
は適当ではなかった。For this reason, for example, a backpack-shaped swim bladder using an air bag (publication of Utility Model Publication No. 5-9481) or a flotation device using styrene material or kapok cotton as a float material (publication of Utility Model Publication No. 36-24093, Publication of Utility Model Publication No. 38-11567) However, in the former, there is a disadvantage that the air bag itself floats separately from the body, impairing stability, and there is a risk of loss of buoyancy due to air leakage from the mouthpiece or tearing of the bag. Since the flotation device is wrapped around the abdomen or chest or is in contact with the chest, it makes the body unstable while swimming and also hinders the movement of the limbs. It was not suitable as a tool.

本考案は先に上記の如き欠点の無い幼児や水泳初心の児
童が着用するのに適した水泳練習用浮袋を提案した（特
開昭５５−１２９０７２−ｑ公報参照）。The present invention has previously proposed a swim bladder for swimming practice that does not have the above-mentioned drawbacks and is suitable for being worn by infants and children who are beginners in swimming (see Japanese Patent Laid-Open No. 129072-q 1982).

すなわち、防水布製の袋体の内部を上下に区画し、形成
された各部の袋内に発泡樹脂の粒状物を充填した小袋を
夫々複数個収納すると共に袋体の下端に開閉自在の袋口
を設は且つ袋体の背部に袋体を身体の背面に密接に密着
させる肩掛縁と腰縁を設けた水泳練習用浮袋を提案した
。That is, the inside of a bag made of waterproof fabric is divided into upper and lower parts, each of which stores a plurality of small bags filled with foamed resin particles, and has a bag opening that can be opened and closed at the bottom end of the bag. We also proposed a swim bladder for swimming practice in which a shoulder edge and a waist edge are provided on the back of the bag to bring the bag into close contact with the back of the body.

この浮袋は身体との密着性がよく、幼児や初心の児童の
水泳練習用として適したものであるが、本考案者は更に
検討を重ねた結果、上記の如き袋体の上下各部に小孔を
設け、各部の袋内に水を侵入させることによって、浮袋
と身体との密着性が更によくなり、又遊泳中浮袋に対す
る水の抵抗が著しく少くなり、しかも浮袋の浮力には殆
んど影響が無いことを見出し本考案を完成した。This swim bladder has good adhesion to the body and is suitable for swimming practice for infants and beginners, but after further study, the inventor of the present invention created small holes in the upper and lower parts of the bag as described above. By allowing water to enter the bags of each part, the adhesion between the swim bladder and the body is improved, and the resistance of water to the swim bladder during swimming is significantly reduced, and it has almost no effect on the buoyancy of the swim bladder. He discovered that there was no such thing and completed the present invention.

これまで袋内にはなるべく水が入らない方がよいと考え
られ、そのような対策が採られていたのであるが、袋に
小孔を設け、袋内に水を侵入させることによって、小袋
内に収められた発泡樹脂粒子による浮力には殆んど影響
なく、浮袋の長体への馴染みによる密着性が極めてよく
なり、使用者が全身の動きを殆んど拘束されずに遊泳で
きるようになったことは全く予期しないことであった。Up until now, it was thought that it was better to prevent water from entering the bag as much as possible, and such measures had been taken, but by making small holes in the bag and allowing water to enter the bag, The buoyancy caused by the foamed resin particles contained in the swim bladder is hardly affected, and the adhesion to the long body of the swim bladder is extremely good, allowing users to swim with almost no restriction in their whole body movements. What happened was completely unexpected.

更に、小孔として網目を用い、図面に示したように上部
の袋のほぼ中央部又はこれより上部と、下部の袋の下端
部に網目を設けることにより、遊泳時に袋内に侵入する
水の流通性がよくなり、浮袋自体の水流抵抗を著しく少
くすることができた。Furthermore, by using a mesh as the small hole and providing the mesh at approximately the center or above the center of the upper bag and the lower end of the lower bag as shown in the drawing, water that enters the bag during swimming can be prevented. The flowability was improved, and the water flow resistance of the swim bladder itself was significantly reduced.

以下、図面に示された本考案の実施例について本考案を
説明する。Hereinafter, the present invention will be described with reference to embodiments of the present invention shown in the drawings.

第１図は本考案の浮袋の一実施例を示す外側正面図、第
２図は同側面図、第３図は同内側正面図、第４図は同内
部を示す説明図である。FIG. 1 is an outside front view showing one embodiment of the swim bladder of the present invention, FIG. 2 is a side view of the same, FIG. 3 is an inside front view of the same, and FIG. 4 is an explanatory diagram showing the inside thereof.

浮袋の本体を使用者の背面に適合する扁平状の袋体１と
して作り、内部には第４図に示すように、浮体として発
泡樹脂の粒状物２を詰めた小袋３が適当数収容されてい
る。The main body of the swim bladder is made as a flat bag body 1 that fits the back of the user, and an appropriate number of small bags 3 filled with foamed resin particles 2 as floating bodies are housed inside as shown in FIG. There is.

粒状物２は小袋内で遊動でき・る状態となるようにゆる
く詰められていることが好ましく、このようにすること
によって浮袋の身体への適応性をより良くすることがで
きる。It is preferable that the particulate matter 2 is loosely packed so that it can move freely within the pouch, and by doing so, the adaptability of the swim bladder to the body can be improved.

上記袋体１は防水布あるいは通常の布で作られ、外側の
面の上部の一部及び下縁部に横方向に多数の細孔４，４
′を有する網体を設ける。The bag body 1 is made of waterproof cloth or ordinary cloth, and has many pores 4, 4 in the upper part and the lower edge of the outer surface in the horizontal direction.
′ is provided.

このような網体を設ける代りに布部の同様な位置に多数
の細孔を設けてもよい。Instead of providing such a net, a large number of pores may be provided at similar positions in the cloth portion.

更に網体の幅は適当でよく、場合によっては外側の面全
体を細孔を有する網体としてもよい。Furthermore, the width of the net may be appropriate, and in some cases, the entire outer surface may be a net having pores.

細孔又は網目の大きさは水が自由に人出できる程度であ
れば特に制限は無いが、余り大きいと、小袋が破れた場
合に小袋内の粒状物２が漏れてプール等に散乱し汚すの
で好ましくない。There is no particular restriction on the size of the pores or mesh as long as the water can flow freely, but if it is too large, if the pouch is torn, the particulate matter 2 inside the pouch will leak and scatter in pools etc., making a mess. So I don't like it.

袋体１の内部のほぼ中央部にスナップボタン等の止具５
を付け、袋体内部を中間で開閉できるように上下に区画
する。A fastener 5 such as a snap button is located approximately in the center of the inside of the bag 1.
The inside of the bag is divided into upper and lower parts so that it can be opened and closed in the middle.

このように袋体を上下に区画することによって、小袋３
を夫々適当数上下の袋部に分散し、又袋体は止具部を境
にして屈曲が自在になるから、袋体１は三部分として上
部は肩掛バンド９により、下部は腰バンド７によっテ常
に身体背面に密着させることができる。By dividing the bag body into upper and lower parts in this way, the small bag 3
The bag body 1 is divided into three parts: the upper part is connected to the shoulder band 9, and the lower part is connected to the waist band 7. Therefore, it can always be kept in close contact with the back of the body.

さらに、袋体１の下縁から１側縁の上部区画域にわたっ
て一連の袋口６を開設し、ファスナーにより開閉自在に
しである。Further, a series of bag openings 6 are provided from the lower edge of the bag body 1 to the upper section of one side edge, and can be opened and closed with a zipper.

袋口上を上部区画域まで延長することにより、下部区域
は勿論、上部区域の小袋のｉ出し入れ、移動を容易に行
うことができる。By extending the top of the bag opening to the upper section, it is possible to easily take in and out of the pouches in the upper section as well as the lower section and move them.

この袋体１の内側、すなわち使用者の背面と接する側の
下方に腰バンド７がその中間部分を袋体とほぼ全幅にわ
たって設けた袋帯部８に収容すると共に袋体又は袋帯部
に縫着して取り付けられ、プまた左右一対の肩掛バンド
９，９′が上端を袋体１の上部に縫着して取付けられて
いる。Inside the bag 1, that is, at the lower part of the side that contacts the back of the user, a waist band 7 is housed at its intermediate portion in a bag belt part 8 that spans almost the entire width of the bag body, and is sewn to the bag body or the bag belt part. A pair of left and right shoulder bands 9, 9' are attached by sewing their upper ends to the upper part of the bag body 1.

これら各バンドはその長さを尾錠により自由に調整して
相互に接続され、袋体１を使用者の身体背部に密接して
装着できるようになっている。The lengths of these bands can be freely adjusted using buckles and are connected to each other, so that the bag 1 can be worn closely on the back of the user's body.

なお、１ｏは補助バンド（図示せず）を使用するバンド
通し輪であり、初心者で前記バンド７及び９，９′だけ
では袋体１の装着に不安を感する場合に更に確実に身体
に装着するために用いるものであって、場合により省い
ても差支えない。Note that 1o is a band loop that uses an auxiliary band (not shown), and if you are a beginner and feel uneasy about wearing the bag 1 with just the bands 7, 9, and 9', you can use it to more securely attach it to your body. It is used for this purpose, and may be omitted depending on the situation.

この考案の浮袋を使用する場合には、袋体１を左右の肩
掛バンド９，９′及び腰バンド７によって身体背部に密
接させて装着させる。When using the swim bladder of this invention, the bag body 1 is attached closely to the back of the body using the left and right shoulder bands 9, 9' and the waist band 7.

袋体１はそノ全幅にわたって添着された腰バンド７によ
りその下方部が身体背部に密接していると共に、袋体１
は全体が扁平状である上に中央部を境として上下に屈折
できるから、身体背部に屈曲運動によく追随し、特に袋
体１の上部と下部に多数の通水孔又は細孔４，４′が開
設されているので水の侵入によって袋体１内の空気は瞬
時に追い出され、従来の空気袋のように水中で身体から
遊離するようなことはなく、上、下に屈折できる構造と
相俟って、身体への順応性と密着性が極めて良くなり、
又、袋体１の上部と下部に多数の通水孔を設けることに
より水の流通が自由になり、袋体に対する水の抵抗が少
なくなって遊泳し易くなっている。The lower part of the bag 1 is in close contact with the back of the body due to the waist band 7 attached over its entire width.
Since the entire body is flat and can be bent up and down with the center as a boundary, it follows the bending movement of the body's back well, and in particular, there are many water passage holes or pores 4, 4 in the upper and lower parts of the bag body 1. ′ is opened, so the air inside the bag body 1 is instantly expelled when water enters, and unlike conventional air bags, it does not come loose from the body underwater, and it has a structure that can be bent upwards and downwards. Together, it has extremely good adaptability and adhesion to the body,
Furthermore, by providing a large number of water holes in the upper and lower parts of the bag 1, water can flow freely, and water resistance against the bag is reduced, making it easier to swim.

更に、袋内に浸水した水は内部に収められた粒子入りの
小袋間の潤滑油の役をなして小袋を泳法体形に応じて滑
かに変動させるが、袋体を上下の部分に区分しであるの
で小袋方法きく一方に変動することはない。Furthermore, the water that has entered the bag acts as a lubricant between the pouches containing particles, allowing the pouches to move smoothly according to the shape of the swimmer's body. Therefore, the sachet method will not fluctuate in one direction.

また、この場合、浸水した水は小量であり浮袋の浮力に
殆んど影響を与えない。In addition, in this case, the amount of water that has flooded is small and has little effect on the buoyancy of the swim bladder.

さらに、小袋３内の粒状物２を遊動できる程度にゆるく
充填しとおけば、身体の動きに従って粒状物２が各小袋
３内に自由に動き、袋体１全体が常に身体に適合した状
態に保たれ、装着感を殆んど感じさせずに快適に使用す
ることができる。Furthermore, if the granules 2 in the pouches 3 are filled loosely enough to allow movement, the granules 2 will move freely into each pouch 3 according to the movement of the body, and the entire bag 1 will always be in a state that fits the body. It can be used comfortably with almost no feeling of wearing.

小袋３は上下夫々の部分で数個用いているので、上達に
応じてその数を減らしたり、或いは泳法により区画別に
数を変えることができるが、本考案においては、上部区
域にまで延びている長い一連の袋口６を設けであるので
、小袋の出し入れや移動が容易にできる。Since several pouches 3 are used in each of the upper and lower sections, the number can be reduced as the swimmer improves, or the number can be changed for each section depending on the swimming style, but in the present invention, they extend to the upper section. Since a long series of bag openings 6 are provided, the bag can be easily taken out and taken out and moved.

また、使用後は袋口を開いたまま、或いは小袋３を取り
出して乾かすことにより速かに乾燥させることができる
。Further, after use, the bag can be quickly dried by leaving the bag mouth open or by taking out the bag 3 and drying it.
