Description

本願発明は、軟質な合成樹脂シートによって空気室を有する浮き輪などの空気袋に取り付けられる空気栓、及び空気栓に差し込まれて空気室内に給気又は排気を行う給排気具を備えた空気栓ユニットに関するものである。 The present invention relates to an air plug that is attached to an air bag such as a floating ring having an air chamber by a soft synthetic resin sheet, and an air plug provided with an air supply / exhaust device that is inserted into the air plug to supply or exhaust air into the air chamber It is about the unit.

浮き輪、枕等の柔軟な合成樹脂シートによって形成された空気袋は、空気栓から空気室内へ給気され、体積を大きくして使用される。また、使用後の空気袋は、空気栓から外部へ排気され、空気袋の体積を小さくして折り畳んで保管される。   An air bag formed of a flexible synthetic resin sheet such as a float or a pillow is supplied from an air plug into an air chamber and used with a larger volume. The used air bag is exhausted from the air plug to the outside, and the air bag is reduced in volume and stored in a folded state.

ところで、この空気栓は、一般的に図７に示すものが主流であり、空気袋２７と同じ合成樹脂で形成された空気栓２２の基部２１が熱や高周波によって空気袋２７の表面に溶着されて、取り付けられている。また、空気栓２２は、その中心に空気袋２７に対して給排気を行うための給排気口２２aを備えている。この給排気口２２aは「有底筒状」のものに形成され、その下部に入れた切込み２２ｂによって、「有底筒状」の底部分が弁部２２ｃとなっている。   By the way, this air plug is generally the one shown in FIG. 7, and the base 21 of the air plug 22 formed of the same synthetic resin as the air bag 27 is welded to the surface of the air bag 27 by heat or high frequency. Attached. In addition, the air plug 22 includes a supply / exhaust port 22a for supplying / exhausting air to / from the air bag 27 at the center thereof. The air supply / exhaust port 22a is formed in a "bottomed cylindrical shape", and a bottom portion of the "bottomed cylindrical shape" serves as a valve portion 22c by a notch 22b formed in the lower portion thereof.

次に、空気栓２２の使用態様について説明する。まず、空気室２８内に空気を給気するときは、給排気口２２aの上部を口で銜えて空気を吹き込むことで、図７の仮想線で示すように空気圧により弁部２２ｃが開放されて、給気が行われる。一方、空気室２８内の空気を排気するときは、立設部２２ｄを指で摘んで絞ることで、弁部２２ｃが開放されて、排気が行われる。また、空気室２８内の空気の漏れを防止するときは、給排気口２２aの上端に一体形成された栓部２４が、給排気口２２aに差し込まれる。   Next, how the air stopper 22 is used will be described. First, when supplying air into the air chamber 28, the valve portion 22c is opened by air pressure as shown by the phantom line in FIG. The air supply is done. On the other hand, when the air in the air chamber 28 is exhausted, the valve portion 22c is opened and exhausted by grasping the standing portion 22d with a finger and squeezing it. In order to prevent air leakage in the air chamber 28, the plug 24 integrally formed at the upper end of the air supply / exhaust port 22a is inserted into the air supply / exhaust port 22a.

このように、空気室２８内への給排気は、空気栓２２単体のみで行うことが可能であるが、より短時間で簡単に給排気を可能とするものとして、例えば図８の（a）に示すポンプ式の給気装置や、図８の（ｂ）に示す排気具が用いられてきた。   In this way, air supply / exhaust into the air chamber 28 can be performed only by the air plug 22 alone, but it is possible to supply / exhaust easily in a shorter time. For example, FIG. The pump-type air supply device shown in FIG. 8 and the exhaust device shown in FIG. 8B have been used.

この図８の（a）に示すポンプ（ポンプ本体は不図示）式の給気装置は、エアホースDの先端に取り付けた給気具２５を空気栓２２の給排気口２２aに差込んで、ポンプ本体から送られた空気を空気室２８内へと給気する。ところで、給排気口２２aのサイズ（口径、深さ）は用途に応じて様々なものがあるため、給排気口２２aのサイズに合わせた数種類の給気具２５が用意されており、ユーザは、給排気口２２aのサイズに合う給気具２５を適宜選択し、それをエアホースDの先端に取り付けて利用している。   The pump-type air supply device (pump main body not shown) shown in FIG. 8A is configured by inserting an air supply device 25 attached to the tip of the air hose D into the air supply / exhaust port 22a of the air plug 22. Air sent from the main body is supplied into the air chamber 28. By the way, since there are various sizes (diameters and depths) of the air supply / exhaust port 22a depending on the application, several types of air supply devices 25 are prepared according to the size of the air supply / exhaust port 22a. An air supply device 25 suitable for the size of the air supply / exhaust port 22a is selected as appropriate, and is attached to the tip of the air hose D for use.

次に、図８の（ｂ）に示す排気具３５は、排気具３５の先端に弁開放部３５ｃ、排気具３５内部に外部と空気室２８内とを連通させる連通孔３５eを備えており、その先端側を空気栓２２の給排気口２２aに差し込むことで、弁開放部３５ｃが弁部２２ｃを開放する。すなわち、空気室２８内の空気は、開放された弁部２２ｃから排気具３５の連通孔３５eを通して外部に排気されることになる。   Next, the exhaust device 35 shown in FIG. 8 (b) includes a valve opening 35c at the tip of the exhaust device 35, and a communication hole 35e that communicates the inside of the exhaust device 35 with the inside of the air chamber 28. By inserting the distal end side into the air supply / exhaust port 22a of the air plug 22, the valve opening part 35c opens the valve part 22c. That is, the air in the air chamber 28 is exhausted to the outside through the communication hole 35e of the exhaust tool 35 from the opened valve portion 22c.

上述したように、給気具２５や排気具３５を利用すれば、空気室２８への給排気が短時間で簡単なものになり、非常に便利である。しかしその反面、この給気具２５及び排気具３５は、使用するときに別途用意しなければならないし、これらは小さい部品であるため使用しないときに、何処かに保管しても失いやすく、使い勝手が悪いものであった。   As described above, if the air supply tool 25 and the exhaust tool 35 are used, the air supply and exhaust to the air chamber 28 can be simplified in a short time, which is very convenient. However, the air supply device 25 and the exhaust device 35 must be prepared separately when they are used. Since these are small parts, they are easy to lose even if stored somewhere when they are not used. Was bad.

そこで、本願発明は上記問題に鑑み、給排気具を別途用意する必要がなくて失うこともない、使い勝手のよい空気栓ユニットを提供するものである。 Therefore, in view of the above problems, the present invention provides an easy-to-use air plug unit that does not require a separate air supply / exhaust tool and is not lost.

上記課題を解決するために、先ず、請求項１に係る本願発明の空気栓ユニット２０は、図５に示す記号を用いて説明すると、軟質な合成樹脂シートによって空気室２８を有する空気袋１７に取り付けられた基部１１と、この基部１１に設けた空気栓１２及び収容部１３と、前記空気栓１２に備えた栓部１４と、給排気具１５とを備えた空気栓ユニット２０であって、前記空気栓１２を、前記空気袋１７内への空気の出入を行うものとし、前記収容部１３を、前記給排気具１５を収容し得るものとし、前記栓部１４を、前記空気栓１２に差し込んだとき、前記空気袋１７からの空気の漏れを防止するものとし、前記給排気具１５を、前記空気栓１２に差し込んだとき、前記空気袋１７に対する給気又は排気を行うものとしたことを特徴としている。   In order to solve the above-mentioned problem, first, the air plug unit 20 of the present invention according to claim 1 will be described with reference to the symbols shown in FIG. 5, and the air bag 17 having the air chamber 28 is formed by a soft synthetic resin sheet. An air plug unit 20 including an attached base 11, an air plug 12 and a housing 13 provided on the base 11, a plug 14 provided in the air plug 12, and an air supply / exhaust tool 15. The air plug 12 is designed to allow air to enter and exit from the air bag 17, the accommodating portion 13 can accommodate the air supply / exhaust tool 15, and the plug portion 14 is connected to the air plug 12. When inserted, the air leakage from the air bag 17 is prevented, and when the air supply / exhaust tool 15 is inserted into the air plug 12, the air bag 17 is supplied with air or exhausted. Features .

上記特徴によれば、空気袋１７に対する給気又は排気を行う給排気具１５は、すでに空気栓ユニット２０に備えられているため、空気栓１２に差し込んで給気又は排気するときに別途用意する必要がない。さらに、給排気具１５を収容し得る収容部１３を備えているため、給排気具１５は、使用しないとき収容部１３に収容されて保管される。つまり、給排気具１５は空気袋１７に取り付けられた空気栓ユニット２０に備えられているので、別途用意する必要もなく、また何処かへ失えてしまうこともない。また、給排気具１５は、収容部１３へ収容されるので、収まりよく邪魔にはならないのである。   According to the above feature, the air supply / exhaust tool 15 that supplies or exhausts air to / from the air bag 17 is already provided in the air plug unit 20, and therefore is separately prepared when the air plug 12 is inserted and supplied or exhausted. There is no need. Furthermore, since the housing part 13 that can house the air supply / exhaust tool 15 is provided, the air supply / exhaust tool 15 is housed and stored in the housing part 13 when not in use. That is, since the air supply / exhaust tool 15 is provided in the air plug unit 20 attached to the air bag 17, it is not necessary to prepare it separately, and it is not lost anywhere. Moreover, since the air supply / exhaust tool 15 is accommodated in the accommodating part 13, it is settled and does not get in the way.

この空気栓ユニット２０は、空気栓１２と収容部１３とが互いに近接して設けられているが、基部１１をさらに大きくして、空気栓１２と収容部１３とを離して設けることもできる。また、給排気具１５は、収容部１３の上端から延設された柔軟な合成樹脂の延設帯１６に取り付けられているため、収容部１３への収容、及び空気栓１２への差込みが無理なくできる。なお、延設帯１６に取り付けられた給排気具１５が、空気栓１２及び収容部１３に差し込めるのであれば、延設帯１６は、収容部１３の上端以外の他の場所からでも、延設することができる。例えば、図６に示す空気栓ユニット５０のように、給排気具４５は、空気栓４２の上端から延設された延設帯４６ｃに取り付けることが出来る。この延接帯４６ｃは、給排気具４５を空気栓４２の給排気口４２aに差し込むことができ、尚且つ収容部４３の収容口４３aに収容することができるように、延設帯４６ｂよりも長く形成されている。さらに、延設帯４６ｂ及び４６ｃは、柔軟な合成樹脂に限られず、ひも等の自由に折り曲げられるものであればよい。また、延設帯４６ｃへの給排気具４５の取り付け方法は、接着材による接着、熱等による溶着、又は着脱可能な取付部材を用いてもよい。   In the air plug unit 20, the air plug 12 and the accommodating portion 13 are provided close to each other, but the base portion 11 can be further enlarged so that the air plug 12 and the accommodating portion 13 are separated from each other. Further, since the air supply / exhaust tool 15 is attached to a flexible synthetic resin extending band 16 extending from the upper end of the accommodating portion 13, it cannot be accommodated in the accommodating portion 13 and inserted into the air plug 12. It can be lost. If the air supply / exhaust tool 15 attached to the extension band 16 can be inserted into the air plug 12 and the accommodating part 13, the extension band 16 can be extended from other places than the upper end of the accommodating part 13. Can be set. For example, as in the air plug unit 50 shown in FIG. 6, the air supply / exhaust tool 45 can be attached to an extended band 46 c extending from the upper end of the air plug 42. The extension band 46 c is more than the extension band 46 b so that the air supply / exhaust tool 45 can be inserted into the air supply / exhaust port 42 a of the air plug 42 and can be stored in the storage port 43 a of the storage portion 43. It is formed long. Furthermore, the extension bands 46b and 46c are not limited to a flexible synthetic resin, and may be any one that can be bent freely such as a string. In addition, as a method of attaching the air supply / exhaust tool 45 to the extension band 46c, adhesion by an adhesive, welding by heat or the like, or a detachable attachment member may be used.

さらに、この給排気具１５は、図１〜６に示すものに限られず、従来から用いられている図８の（a）の給気具２５や、図８の（ｂ）に示す排気具３５であってもよい。勿論、空気栓１２に差し込んで給気又は排気を行うものであれば、これらに限られるものではない。   Further, the air supply / exhaust tool 15 is not limited to that shown in FIGS. 1 to 6, and the air supply apparatus 25 shown in FIG. 8 (a) and the exhaust tool 35 shown in FIG. 8 (b) which have been conventionally used. It may be. Of course, it is not limited to these as long as it is inserted into the air plug 12 to supply or exhaust air.

次に、請求項２に係る本願発明の空気栓ユニット１０は、図３に示す記号を用いて説明すると、前記栓部４と前記給排気具５とを連接したことを特徴としている。   Next, the air plug unit 10 of the present invention according to claim 2 is characterized in that the plug portion 4 and the air supply / exhaust tool 5 are connected to each other when described using the symbols shown in FIG.

ここで、この栓部４と給排気具５とを連接するとは、延設帯６によって、栓部４と給排気具５とを連ねて接続することをいう。そして、給気又は排気を行うときは、先ず空気栓２の給排気口２aに差し込まれている栓部４をはずし、次に空気栓２の給排気口２aに給排気具５を差し込むが、栓部４と給排気具５とが連接されているので、この作業は連続で行い易くなる。また、給気又は排気を行わないときは、図４に示すように空気栓２の給排気口２aに栓部４を差し込み、給排気具５を収容部３の収容口３aに差し込んで収容するが、栓部４と給排気具５とが連接されているので、同様にこの作業も連続で行い易くなり、使い勝手がよいものとなる。   Here, connecting the plug portion 4 and the air supply / exhaust tool 5 means connecting the plug portion 4 and the air supply / exhaust device 5 together by the extension band 6. When supplying or exhausting air, first, the plug portion 4 inserted into the air supply / exhaust port 2a of the air plug 2 is removed, and then the air supply / exhaust tool 5 is inserted into the air supply / exhaust port 2a of the air plug 2. Since the plug part 4 and the air supply / exhaust tool 5 are connected, this operation | work becomes easy to perform continuously. When air supply or exhaust is not performed, the plug portion 4 is inserted into the air supply / exhaust port 2a of the air plug 2 and the air supply / exhaust tool 5 is inserted into the storage port 3a of the storage unit 3 as shown in FIG. However, since the plug portion 4 and the air supply / exhaust tool 5 are connected to each other, this operation can be easily performed continuously and is easy to use.

さらに、請求項３に係る本願発明の空気栓ユニット１０は、図３に示す記号を用いて説明すると、給排気具５が、前記空気栓２の給排気口２a内に差し込まれる第１差込部５aと、この第１差込部５aより大径の第２差込部５ｂと、前記第1差込部５aの先端に一体化した弁開放部５ｃと、前記第２差込部５ｂの外端に一体化されて、空気の注入または排出を行う操作部５ｆと、この操作部５ｆ、第１差込部５a、及び第２差込部５ｂ内に形成されて、外部と前記空気室８とを連通させる連通孔５eとを備えたことを特徴としている。   Further, the air plug unit 10 of the present invention according to claim 3 will be described with reference to the symbols shown in FIG. 3. The first plug is inserted into the air supply / exhaust port 2 a of the air plug 2. A portion 5a, a second insertion portion 5b having a diameter larger than that of the first insertion portion 5a, a valve opening portion 5c integrated at a tip of the first insertion portion 5a, and a second insertion portion 5b. An operation portion 5f integrated with the outer end for injecting or discharging air, and formed in the operation portion 5f, the first insertion portion 5a, and the second insertion portion 5b, and the outside and the air chamber 8 is provided with a communication hole 5e that communicates with the air.

上記特徴によれば、給排気具５は、給排気口２aに差し込まれる第1差込部５aと、この第１差込部５aより大径の第２差込部５ｂとの２種類の差込部を有しているから、空気栓２の給排気口２aの内径が異なったとしても、ほぼ全ての空気栓２に対応することが出来る。   According to the above feature, the air supply / exhaust tool 5 has two types of differences: the first insertion portion 5a inserted into the air supply / exhaust port 2a and the second insertion portion 5b having a larger diameter than the first insertion portion 5a. Since it has the insertion portion, even if the inner diameter of the air supply / exhaust port 2a of the air plug 2 is different, almost all the air plugs 2 can be handled.

すなわち、空気栓２は、柔軟な合成樹脂によって形成されているため、給排気口２aの内径が第１差込部５aの外径より小さい場合は、この第１差込部５aを強く差し込めば、給排気口２aの弾力性によって給排気口２aの内壁と第１差込部５aの外周が密着して空気の漏れを防ぐことになる。反対に、給排気口２aの内径が第１差込部５aの外径より大きい場合は、第２差込部５ｂを強く差し込めば、両者が強く密着して空気の漏れを防ぐことができる。   That is, since the air plug 2 is formed of a flexible synthetic resin, if the inner diameter of the air supply / exhaust port 2a is smaller than the outer diameter of the first insertion portion 5a, the first insertion portion 5a should be inserted strongly. Due to the elasticity of the air supply / exhaust port 2a, the inner wall of the air supply / exhaust port 2a and the outer periphery of the first insertion portion 5a are brought into close contact with each other to prevent air leakage. On the other hand, when the inner diameter of the air supply / exhaust port 2a is larger than the outer diameter of the first insertion portion 5a, if the second insertion portion 5b is inserted strongly, the two can be in close contact with each other to prevent air leakage.

さらに、空気栓２の給排気口２aに差し込まれた給排気具５の弁開放部５ｃが、弁部２ｃを押し開いて開放した状態を維持するため、給排気具５の内部に形成された連通孔５e及び開口部５ｄを通して、空気室８内と外部とが連通することになる。したがって、従来のように空気圧によって弁部２ｃを開放したり、指で摘んで絞ることで弁部２ｃを開放したりしなくても、給排気具２を差し込むだけで弁部２ｃが開放状態となっているため、空気室８に対する給気及び排気が短時間で簡単に行われる。   Further, the valve opening portion 5c of the air supply / exhaust tool 5 inserted into the air supply / exhaust port 2a of the air plug 2 is formed inside the air supply / exhaust device 5 in order to maintain the open state by pushing the valve portion 2c open. The inside of the air chamber 8 communicates with the outside through the communication hole 5e and the opening 5d. Therefore, the valve portion 2c can be opened by simply inserting the air supply / exhaust tool 2 without opening the valve portion 2c by air pressure as in the prior art, or by opening the valve portion 2c by pinching with a finger. Therefore, air supply and exhaust to the air chamber 8 are easily performed in a short time.

従来は、空気室に給排気するための給排気具を別途用意しなければならないし、使用後に何処かに保管しても失くしやすいものであった。しかし、請求項１に係る本願発明によれば、空気室２８に給気又は排気するときは、給排気具１５を別途用意しなくても、既に空気栓ユニット２０に備えられた給排気具１５をそのまま使用できるので使い勝手がよい。更に、給排気具１５を使用しないときは、空気栓ユニット２０に備えられた収容部１３に収容して保管しておけばよいので、失うこともなく、尚且つ邪魔になることもないので、使い勝手がよいのである。 Conventionally, an air supply / exhaust tool for supplying and exhausting air to the air chamber has to be prepared separately, and even if stored somewhere after use, it is easy to lose. However, according to the present invention of claim 1, when air is supplied or exhausted to the air chamber 28, the air supply / exhaust device 15 already provided in the air plug unit 20 is not required even if the air supply / exhaust device 15 is not separately prepared. Can be used as is, so it is easy to use. Furthermore, when the air supply / exhaust tool 15 is not used, it can be stored and stored in the storage portion 13 provided in the air plug unit 20, so it will not be lost and will not get in the way. It is easy to use.

以下に、本願発明を実施するための形態について、図面を用いて説明する。 EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing.

図１は、本願発明の空気栓ユニット１０を浮き輪Xに取り付けた斜視図を示している。この空気栓ユニット１０は、浮き輪X以外にも、空気枕、エアマット等の軟質な合成樹脂シートによって空気室を有する多種多様な製品に用いることができる。   FIG. 1 shows a perspective view in which an air stopper unit 10 of the present invention is attached to a floating ring X. FIG. In addition to the floating ring X, the air plug unit 10 can be used for various products having an air chamber by a soft synthetic resin sheet such as an air pillow or an air mat.

空気栓ユニット１０の空気栓２及び収容部３は、浮き輪Xの表面より下側に押し込まれている。これは、浮き輪Xを使用する際に、空気栓２及び収容部３が浮き輪X表面に突出していると、邪魔になるからである。また、浮き輪Xの空気袋に対して空気を給気又は排気するときは、空気栓２又は収容部３は、浮き輪Xの表面上に引き上げられて利用される。   The air plug 2 and the accommodating portion 3 of the air plug unit 10 are pushed below the surface of the floating ring X. This is because when the floating ring X is used, if the air plug 2 and the accommodating portion 3 protrude from the surface of the floating ring X, it becomes an obstacle. Further, when air is supplied to or exhausted from the air bag of the floating ring X, the air plug 2 or the accommodating portion 3 is pulled up on the surface of the floating ring X and used.

次に、図２では、この空気栓ユニット１０の構造を詳しく説明する。図２の（a）は、本願発明の空気栓ユニット１０の側面図を、図２の（ｂ）は、本願発明の空気栓ユニット１０の平面図を示している。   Next, in FIG. 2, the structure of the air plug unit 10 will be described in detail. 2A shows a side view of the air plug unit 10 of the present invention, and FIG. 2B shows a plan view of the air plug unit 10 of the present invention.

空気栓２及び収容部３は、基部１上に軟質な合成樹脂で一体形成されている。この空気栓２及び収容部３は、基部１の上側に位置するように、立設部２ｄ、３ｄによってそれぞれ支持されている。この立設部２ｄ、３ｄは、柔軟な合成樹脂で形成されているため、空気栓２及び収容部３を基部１の下側に位置するように押し込むことができる。したがって、図１に示すように、浮き輪Xを使用するときには、空気栓２及び収容部３は浮き輪Xの表面より下側に邪魔にならないように押し込まれる。 The air plug 2 and the accommodating portion 3 are integrally formed on the base portion 1 with a soft synthetic resin. The air plug 2 and the accommodating portion 3 are respectively supported by the standing portions 2d and 3d so as to be positioned above the base portion 1. Since the standing portions 2d and 3d are formed of a flexible synthetic resin, the air stopper 2 and the accommodating portion 3 can be pushed in so as to be positioned below the base portion 1. Therefore, as shown in FIG. 1, when the floating ring X is used, the air stopper 2 and the accommodating portion 3 are pushed below the surface of the floating ring X so as not to get in the way.

空気栓２は、その中心に空気を給排気するための給排気口２aを有し、収容部３はその中心に給排気具５を収容する収容口３aを有している。栓部４及び給排気具５は、空気栓２の上端から延設され、柔軟な合成樹脂で形成された延設帯６上に取り付けられている。ここで、栓部４は延設帯６と一体形成されて取り付けられており、一方の給排気具５は、操作部５ｆの外周に沿って設けられた溝５ｇに、延設帯６の輪部６aをはめ込むことで取り付けられている。なお、給排気具５の延設帯６への取り付け方法は、接着剤による接着や、熱等による溶着、その他の着脱可能な取付手段によるものであってもよい。また、着脱可能な取付手段によるものであれば、ユーザが任意に選んだ給排気具を取り付けることも出来る。   The air plug 2 has an air supply / exhaust port 2a for supplying and exhausting air at the center thereof, and the accommodating portion 3 has an accommodating port 3a for accommodating the air supply / exhaust tool 5 at the center thereof. The plug part 4 and the air supply / exhaust tool 5 extend from the upper end of the air plug 2 and are mounted on an extended band 6 formed of a flexible synthetic resin. Here, the plug portion 4 is integrally formed and attached to the extension band 6, and one air supply / exhaust tool 5 is attached to a groove 5 g provided along the outer periphery of the operation portion 5 f in a ring of the extension band 6. It is attached by fitting the part 6a. Note that the method of attaching the air supply / exhaust tool 5 to the extension band 6 may be based on adhesion by an adhesive, welding by heat or the like, or other removable attachment means. Moreover, if it is based on the attachment means which can be attached or detached, the air supply / exhaust tool arbitrarily selected by the user can also be attached.

次に、給排気具５の構造について説明する。この給排気具５の第１差込部５aは、その先端に、空気の出入のための開口を有したもので、この開口の周囲には、「逆門型」の弁開放部５ｃが形成されている。また、この第1差込部5aの下端側には、この第１差込部５aより直径の大きい第２差込部５ｂが連なっており、これらの第１差込部５a及び第２差込部５ｂには、先端の開口に連なる連通孔５eが形成されている。さらに、第２差込部５ｂの他端には、第２差込部５ｂより直径の大きい操作部５ｆが連続しており、この操作部５ｆの中心には、連通孔５eに連なる開口部５ｄが設けられている。ところで、この給排気具５は径の異なる２種類の差込部を有しているため、本願発明の空気栓ユニット１０を有しない空気栓の径が異なる他の浮き輪等に対しても、給排気具５を用いて給排気を行うことも出来る。   Next, the structure of the air supply / exhaust tool 5 will be described. The first insertion part 5a of the air supply / exhaust tool 5 has an opening for air in and out at the tip, and a "reverse gate type" valve opening part 5c is formed around the opening. Has been. Moreover, the 2nd insertion part 5b whose diameter is larger than this 1st insertion part 5a continues in the lower end side of this 1st insertion part 5a, and these 1st insertion part 5a and 2nd insertion are connected. The part 5b is formed with a communication hole 5e continuous with the opening at the tip. Further, an operation portion 5f having a diameter larger than that of the second insertion portion 5b is connected to the other end of the second insertion portion 5b, and an opening portion 5d connected to the communication hole 5e is provided at the center of the operation portion 5f. Is provided. By the way, since this air supply / exhaust tool 5 has two types of insertion parts with different diameters, for other floating rings with different diameters of air plugs that do not have the air plug unit 10 of the present invention, Supply / exhaust can also be performed using the supply / exhaust tool 5.

では、この給排気ユニット１０を、軟質な合成樹脂シートによって空気室８を有する空気袋７に取り付けて使用する態様を図３で説明する。給排気ユニット１０は、熱や高周波によって空気袋７の表面に基部１が溶着されることで、取り付けられている。また、空気栓２自体の構造は、図７の従来の空気栓２２と同じである。 Then, the aspect which attaches and uses this air supply / exhaust unit 10 to the air bag 7 which has the air chamber 8 with a soft synthetic resin sheet is demonstrated in FIG. The air supply / exhaust unit 10 is attached by the base 1 being welded to the surface of the air bag 7 by heat or high frequency. The structure of the air plug 2 itself is the same as that of the conventional air plug 22 of FIG.

空気室８に給気する際には、給排気具５を空気栓２の給排気口２aに差し込むことにより、弁開放部５ｃの先端が弁部２ｃに当接して、弁部２ｃを開放する。この状態で、操作部５ｆの上端側を口で銜え、開口部５ｄへ向けて息を送り込めば、連通孔５eを通して空気室８への給気が行われる。また、開口部５ｄの直径は、エアホースDの先端（図８の（a）を参照）の直径より小さいため、エアホースDの先端を開口部５ｄに強固に差し込むことができ、ポンプ式の給気装置を利用することもできる。   When supplying air to the air chamber 8, by inserting the air supply / exhaust tool 5 into the air supply / exhaust port 2a of the air plug 2, the tip of the valve opening portion 5c comes into contact with the valve portion 2c to open the valve portion 2c. . In this state, if the upper end side of the operation portion 5f is held with a mouth and breath is sent toward the opening portion 5d, the air chamber 8 is supplied with air through the communication hole 5e. Further, since the diameter of the opening 5d is smaller than the diameter of the tip of the air hose D (see FIG. 8A), the tip of the air hose D can be firmly inserted into the opening 5d. A device can also be used.

一方、排気する際には、この給排気具５を空気栓２の給排気口２aに差し込んだ状態で放置すれば、弁開放部５ｃによって弁部２ｃが開放されているので、連通孔５eを通して開口部５ｄから外部へと、空気室８の空気が排気されることになる。このように、給排気具５単体で、給気と排気の両方を行うことができる。   On the other hand, when evacuating, if this air supply / exhaust tool 5 is left in a state where it is inserted into the air supply / exhaust port 2a of the air plug 2, the valve portion 2c is opened by the valve opening portion 5c. The air in the air chamber 8 is exhausted from the opening 5d to the outside. In this way, both air supply and exhaust can be performed with the air supply / exhaust tool 5 alone.

次に、給排気具５を空気栓２の給排気口２aから引き抜いて、空気室８に対する給排気を終える。そうすると、給排気具５の弁開放部５ｃによって開放されていた弁部２ｃが、その軟質性によって元に戻り、図４に示すように、給排気口２aは有底筒状となる。そして、空気栓２の給排気口２aに栓部４を差し込み、そのまま、栓部４に連接されている給排気具５を収容部３の収容口３aに差し込んで収容する。このように、栓部４及び給排気具５は、柔軟な合成樹脂で形成された延設帯６上に連接されているので、この一連の作業を連続で行いやすい。もちろん、この状態から、栓部４及び給排気具５を引き抜き、給排気するために給排気具５を給排気口２aに差し込む一連の作業も連続で行いやすい。なお、収容口３aの深さは、給排気口２aよりも深くなっており、給排気具５の先端の弁開放部５ｃまで確実に収容できるようになっている。   Next, the air supply / exhaust tool 5 is pulled out from the air supply / exhaust port 2a of the air plug 2 to complete the supply / exhaust to the air chamber 8. If it does so, the valve part 2c opened by the valve opening part 5c of the air supply / exhaust tool 5 will return by the softness | flexibility, and as shown in FIG. 4, the air supply / exhaust port 2a becomes a bottomed cylindrical shape. Then, the plug portion 4 is inserted into the air supply / exhaust port 2 a of the air plug 2, and the air supply / exhaust tool 5 connected to the plug portion 4 is inserted into the storage port 3 a of the storage unit 3 and stored. Thus, since the plug part 4 and the air supply / exhaust tool 5 are connected on the extension band 6 formed of a flexible synthetic resin, it is easy to perform this series of operations continuously. Of course, from this state, a series of operations for pulling out the plug portion 4 and the air supply / exhaust device 5 and inserting the air supply / exhaust device 5 into the air supply / exhaust port 2a in order to supply and exhaust air can be easily performed continuously. The depth of the storage port 3a is deeper than that of the air supply / exhaust port 2a so that the valve opening 5c at the tip of the air supply / exhaust tool 5 can be securely stored.

また、空気栓２と収容部３の構造は、空気栓２の給排気口２aと収容部３の収容口３a以外は、すべて共通である。さらに、収容口３aは、給排気口２aと比べると、その深さが異なる点、及び弁部２ｃを形成するための切込み２ｂがない点を除けば、給排気口２aの形状と類似している。したがって、空気栓２と収容部３の形状は、多くの部分で共通しており、製造コストを削減することができる。なお、収容部３の形状は、給排気具５を収容できるものであればよく、柱体や錐体、その他の形状でもよい。   Moreover, the structure of the air plug 2 and the accommodating part 3 is the same except for the air supply / exhaust port 2a of the air stopper 2 and the accommodating port 3a of the accommodating part 3. Further, the housing port 3a is similar to the shape of the air supply / exhaust port 2a except that the depth is different from that of the air supply / exhaust port 2a and that there is no notch 2b for forming the valve portion 2c. Yes. Therefore, the shape of the air plug 2 and the accommodating part 3 is common in many parts, and can reduce manufacturing cost. In addition, the shape of the accommodating part 3 should just be a thing which can accommodate the air supply / exhaust tool 5, and a pillar, a cone, and another shape may be sufficient as it.

なお、本願発明の空気栓ユニットは、上記の実施例に限定されず、特許請求の範囲に記載された範囲、実施形態の範囲で、種々の変形例、組み合わせが可能であり、これらの変形例、組み合わせもその権利範囲に含むものである。   The air plug unit of the present invention is not limited to the above-described examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments. Combinations are also included in the scope of rights.
