本発明は、主に住宅に設けられる家庭用の蛇口に使用される蛇口用接続アダプタに係り、特に、種々の形状の蛇口と管体とを接続して蛇口からの流体を管体に流す蛇口用接続アダプタに関する。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection adapter for a faucet mainly used for a home faucet provided in a house, and more particularly, a faucet that connects a faucet of various shapes and a pipe body and allows fluid from the faucet to flow into the pipe body For connection adapter.

従来、この種の蛇口用接続アダプタにあっては特許文献１（特開平１０−６１８５４号公報）に記載されたものが知られている。   Conventionally, a faucet connection adapter of this type is known from Patent Document 1 (Japanese Patent Laid-Open No. 10-61854).

図５に示すように、この蛇口用接続アダプタＡ１は、シリコンゴムを素材として射出成型により一体に成型され、外径４０ｍｍ，長さ７０ｍｍの厚肉短管状に形成されている。
また、蛇口用接続アダプタＡ１は、内部に断面略中央部に軸方向に沿うように形成された直径８ｍｍの断面丸形の通水路１と、この通水路１の一端側に形成され蛇口Ｂが接続される蛇口接続部２とを備えている。
蛇口接続部２は、直径８ｍｍにして長さ２０ｍｍの円錐台形状からなる断面丸形孔部２ａに形成されている。更に、この断面丸形孔部２ａに連なる対角線８ｍｍにして長さ２０ｍｍからなる断面角形孔部２ｂとの組合せから構成されるように形成されている。 As shown in FIG. 5, the faucet connection adapter A1 is integrally formed by injection molding using silicon rubber as a material, and is formed into a thick short tube having an outer diameter of 40 mm and a length of 70 mm.
The faucet connection adapter A1 includes a water passage 1 having a round cross section with a diameter of 8 mm formed so as to be along the axial direction at the substantially central portion of the cross section, and a faucet B formed on one end side of the water passage 1. And a faucet connection portion 2 to be connected.
The faucet connection portion 2 is formed in a round hole 2a having a circular truncated cone shape having a diameter of 8 mm and a length of 20 mm. Furthermore, it is formed so as to be constituted by a combination with a cross-sectional square hole portion 2b having a diagonal length of 8 mm and a length of 20 mm connected to the circular cross-section hole portion 2a.

また、蛇口用接続アダプタＡ１の通水路１の他端側は、管体接続部３として使用されている。この管体接続部３には、管体Ｐがねじ込まれ、この管体Ｐをシリコンゴムの弾発力により保持する。
この蛇口用接続アダプタＡ１を使用する場合は、予め、管体接続部３に管体Ｐをねじ込んで接続しておく。次に、蛇口接続部２の断面丸形孔部２ａを蛇口Ｂに当接させて、蛇口Ｂの先端部分が断面角形孔部２ｂに至るまで回動させながら蛇口Ｂ側に押圧して取り付ける。
この際、蛇口接続部２は、拡径するとともにゴムの弾発力により、蛇口Ｂに密着する。
また、この際、蛇口Ｂの形状が、丸形，角形等形状や大きさを異にするものであっても、蛇口接続部２は、蛇口Ｂと断面丸形孔部２ａと断面角形孔部２ｂのうちいずれか一方の孔部と水密状に密着する。

ところで、このような従来の蛇口用接続アダプタＡ１にあっては、ある程度形状の異なる蛇口Ｂに対応はできるものの、蛇口用接続アダプタＡ１が肉厚なので、弾性変形がしにくく、そのため、拡径範囲が小さく蛇口の外径の大きさに対する対応が十分にできず、汎用性に劣るという問題があった。
また、蛇口接続部２を、例えば、シャワーヘッドのような一般に家庭用の蛇口より外形が大きく異形の水の流出部には接続できないという問題があった。 By the way, in such a conventional faucet connection adapter A1, although it can cope with the faucet B having a somewhat different shape, since the faucet connection adapter A1 is thick, it is difficult to be elastically deformed. However, there is a problem in that it is inferior in versatility because it is small and cannot sufficiently cope with the outer diameter of the faucet.
In addition, there is a problem in that the faucet connection portion 2 cannot be connected to a water outflow portion having a larger outer shape than that of a household faucet, such as a shower head.

本発明は上記の問題点に鑑みて為されたもので、弾性変形による拡径範囲を大きくできるようにして、蛇口の種々の形状に対応できることは勿論の事、蛇口より大きく異形の水の流出部にも接続できるようにして汎用性を高めた蛇口用接続アダプタを提供することを目的とする。   The present invention has been made in view of the above problems, and it is possible to cope with various shapes of the faucet by increasing the diameter expansion range due to elastic deformation, as well as outflow of water that is larger than the faucet. It aims at providing the connection adapter for faucets which improved the versatility so that it could connect also to a part.

このような目的を達成するための本発明の蛇口用接続アダプタは、一端側に蛇口に接続される蛇口接続部を有し、他端側に所定の口径を有する管体に接続される管体接続部を有し、上記蛇口と管体とを接続して蛇口からの流体を管体に流す蛇口用接続アダプタにおいて、上記蛇口接続部を、肉厚ｔが０．５ｍｍ≦ｔ≦３ｍｍ，通常状態の内径Ｄ１が１５ｍｍ≦Ｄ１≦４０ｍｍで、弾性変形により内径Ｄ２が１７ｍｍ≦Ｄ２≦５０ｍｍに拡径可能になる樹脂製チューブで構成している。   The faucet connection adapter of the present invention for achieving such an object has a faucet connection portion connected to the faucet on one end side and a pipe body connected to a pipe body having a predetermined diameter on the other end side. In a connection adapter for a faucet that has a connection part and connects the faucet and the pipe body to flow fluid from the faucet to the pipe body, the faucet connection part has a thickness t of 0.5 mm ≦ t ≦ 3 mm, usually The inner diameter D1 of the state is 15 mm ≦ D1 ≦ 40 mm, and the inner diameter D2 can be expanded to 17 mm ≦ D2 ≦ 50 mm by elastic deformation.

これにより、管体が蛇口に直接取り付けられる場合は、管体を直接蛇口に取り付ける一方、管体を直接蛇口に取り付けることができない場合に本発明の蛇口用接続アダプタを用いる。
蛇口用接続アダプタを蛇口に接続する場合には、例えば、管体を予め取り付けた蛇口用接続アダプタの蛇口接続部であるチューブの開口を指等で広げて蛇口に被嵌する。 Thereby, when the pipe body is directly attached to the faucet, the pipe body is directly attached to the faucet, while when the pipe body cannot be directly attached to the faucet, the faucet connection adapter of the present invention is used.
When the faucet connection adapter is connected to the faucet, for example, the opening of the tube, which is the faucet connection portion of the faucet connection adapter to which the tube is attached in advance, is spread with a finger or the like and is fitted on the faucet.

この際、チューブは、拡径可能な比較的薄肉厚の樹脂製チューブで構成されていることから、少しの力でも拡径させ易くなり、蛇口に容易に装着できる。
また、蛇口用接続アダプタが比較的薄肉厚なので、弾性変形し易く、そのため、拡径範囲を大きくでき、蛇口の外径の大きさに対して広い範囲で対応できるようになり、汎用性が向上させられる。
更に、チューブは比較的薄肉厚で変形が容易なので、蛇口の形状を問わず蛇口用接続アダプタを装着できる。また、チューブは変形が容易なので、シャワーヘッド等の蛇口以外のものにも装着でき、汎用性が向上させられる。 At this time, since the tube is made of a relatively thin-walled resin tube that can be expanded in diameter, the tube can be easily expanded with a slight force and can be easily attached to the faucet.
In addition, since the faucet connection adapter is relatively thin and thick, it is easily elastically deformed. Therefore, the diameter expansion range can be enlarged, and the faucet outer diameter can be handled in a wide range, improving versatility. Be made.
Furthermore, since the tube is relatively thin and easily deformed, a faucet connection adapter can be attached regardless of the shape of the faucet. Further, since the tube can be easily deformed, it can be attached to other than a faucet such as a shower head, and versatility is improved.

次に、蛇口を操作して、蛇口から流体を送出する。蛇口から送出された流体は、蛇口接続部であるチューブ，管体接続部を通り管体に流される。
この際、蛇口の外周がチューブで被せられているので、蛇口からの流体のほとんどは、蛇口用接続アダプタの内部を流れて管体に到達する。また、この際、蛇口とチューブの密着性が良いことから、蛇口の外周とチューブの間に隙間ができにくくなり、漏水が防止される。 Next, the faucet is operated to deliver fluid from the faucet. The fluid sent out from the faucet flows through the tube and the tube connecting portion, which are the faucet connecting portion, and flows into the tube.
At this time, since the outer periphery of the faucet is covered with a tube, most of the fluid from the faucet flows inside the faucet connection adapter and reaches the tube. At this time, since the adhesion between the faucet and the tube is good, it becomes difficult to form a gap between the outer periphery of the faucet and the tube, thereby preventing water leakage.

この蛇口用接続アダプタを蛇口から取り外す場合は、蛇口接続部であるチューブを拡径して蛇口から取り外す。この際、チューブの肉厚が比較的薄いことから拡径し易いので、取り外しが容易になる。   When removing this faucet connection adapter from the faucet, the diameter of the tube which is the faucet connection portion is expanded and removed from the faucet. At this time, since the tube is relatively thin, it is easy to expand the diameter, so that it is easy to remove.

また、必要に応じ、上記管体接続部を、上記管体に挿入される管状の管体挿入部と、該管体挿入部に連接されチューブの通常状態の内径Ｄ１よりも大きな外径を有し該チューブが取り付けられる管状のチューブ取付部とを備えて構成し、上記チューブを上記チューブ取付部に被嵌して取り付けている。
チューブをチューブ取付部に被嵌するだけで蛇口接続部に管体接続部を容易に取り付けることができ、構造が簡単なので、コスト安になる。また、チューブが劣化しても交換が容易になる。 In addition, if necessary, the tube body connecting portion has a tubular tube insertion portion inserted into the tube body, and an outer diameter larger than an inner diameter D1 of the tube connected to the tube insertion portion in a normal state. And a tubular tube attachment portion to which the tube is attached, and the tube is fitted and attached to the tube attachment portion.
The tube connecting portion can be easily attached to the faucet connecting portion simply by fitting the tube to the tube attaching portion, and the structure is simple, so the cost is reduced. Moreover, even if the tube deteriorates, the replacement becomes easy.

更に、必要に応じ、上記管体挿入部と上記チューブ取付部とをネジ結合により連接し互いに着脱可能にしている。
この場合、蛇口用接続アダプタを用いる前に、予め、管体の口径に合うように、管体挿入部の外径が最適なものを選ぶとともに、使用するチューブの内径に合うようにチューブ取付部の外径が最適なものを選び、そして、このチューブ取付部に管体挿入部を連接する。そのため、管体やチューブの径に合わせて、組み合わせが選択できるので、管体挿入部と管体を密着し易くでき、また、チューブとチューブ取付部を密着し易くできるので、漏水が確実に防止される。 Further, if necessary, the tube insertion portion and the tube mounting portion are connected by screw coupling so that they can be attached to and detached from each other.
In this case, before using the connection adapter for the faucet, select the tube with the optimum outer diameter so that it matches the diameter of the tube, and the tube mounting part so that it matches the inner diameter of the tube to be used. Choose the one with the optimum outer diameter, and connect the tube insertion part to this tube mounting part. Therefore, the combination can be selected according to the diameter of the tube body and tube, so that the tube body insertion portion and the tube body can be easily adhered, and the tube and tube attachment portion can be easily adhered to each other, so that water leakage is surely prevented. Is done.

また、必要に応じ、上記管体挿入部の外周に、凸条を列設している。内部に流体が流れても、この凸条が管体に引っかかることにより、管体が管体挿入部からはずれにくくなる。   Moreover, if necessary, ridges are arranged on the outer periphery of the tubular body insertion portion. Even if a fluid flows inside, the tube is difficult to be detached from the tube insertion portion by the protrusion being caught by the tube.

更にまた、必要に応じ、上記蛇口接続部を構成するチューブに外挿され該チューブを締め付け及び締め付け解除可能なリングを備えている。
チューブが蛇口とともに締め付けられるので、チューブと蛇口との密着性が向上させられ、蛇口とチューブの間に隙間ができにくくなり、この点でも、漏水が防止される。 Furthermore, a ring that is extrapolated to the tube constituting the faucet connection portion and can tighten and release the tube as necessary is provided.
Since the tube is tightened together with the faucet, the adhesion between the tube and the faucet is improved, and it becomes difficult to form a gap between the faucet and the tube, and also in this respect, water leakage is prevented.

本発明の蛇口用接続アダプタによれば、蛇口接続部の肉厚が比較的薄いことから拡径が容易になり、蛇口への取付け，取外しが容易になるだけでなく、チューブと蛇口との密着性が向上させられ、蛇口とチューブの密着性が良いことから、蛇口とチューブとの間に隙間ができ難くなり、漏水を防止できる。また、肉厚が比較的薄く弾性変形が容易なので、蛇口の種々の形状に対応できるだけでなく、弾性変形による拡径範囲を大きくできるので、蛇口より大きく異形の水の流出部を有するものであっても拡径範囲内の外径を有するものであれば接続できるようになり、この点においても汎用性を向上させることができる。   According to the faucet connection adapter of the present invention, since the faucet connection portion is relatively thin, the diameter can be easily increased, and the faucet can be easily attached to and detached from the faucet. Therefore, it becomes difficult to form a gap between the faucet and the tube, and water leakage can be prevented. In addition, since the wall thickness is relatively thin and elastic deformation is easy, not only can the various shapes of the faucet be accommodated, but also the diameter expansion range due to elastic deformation can be increased, so that it has a water outflow portion that is larger than the faucet and has an irregular shape. However, if it has an outer diameter within the expanded diameter range, it can be connected, and in this respect, versatility can be improved.

以下、添付図面に基づいて、本発明の実施の形態に係る蛇口用接続アダプタについて詳細に説明する。   Hereinafter, a faucet connection adapter according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

図１乃至図３には、本発明の実施の形態に係る蛇口用接続アダプタＡを示している。
この蛇口用接続アダプタＡは、一端側に蛇口Ｂが接続される蛇口接続部２０を有し、他端側に所定の口径を有する管体Ｐが接続される管体接続部３０を有し、蛇口Ｂと管体Ｐとを接続して蛇口Ｂからの流体を管体Ｐに流すものである。
管体Ｐは、例えば、ゴムホース等で構成されている。 1 to 3 show a faucet connection adapter A according to an embodiment of the present invention.
This connection adapter A for a faucet has a faucet connection portion 20 to which a faucet B is connected on one end side, and a tube connection portion 30 to which a tube body P having a predetermined diameter is connected on the other end side, The faucet B and the pipe P are connected, and the fluid from the faucet B is caused to flow to the pipe P.
The pipe body P is comprised by the rubber hose etc., for example.

蛇口接続部２０は、肉厚ｔが０．５ｍｍ≦ｔ≦３ｍｍ，通常状態の内径Ｄ１が１５ｍｍ≦Ｄ１≦４０ｍｍで、弾性変形により内径Ｄ２が１７ｍｍ≦Ｄ２≦５０ｍｍに拡径可能になる樹脂製チューブで構成されている。
望ましくは、蛇口接続部２０である樹脂製チューブ２１は、その肉厚が１．２ｍｍ≦ｔ≦１．３ｍｍ，通常状態の内径Ｄ１が２５ｍｍ≦Ｄ１≦２６ｍｍ，拡径状態の内径Ｄ２が３０ｍｍ≦Ｄ２≦５０ｍｍになるように構成されている。
本発明の実施の形態においては、蛇口接続部２０は、例えば、肉厚ｔ＝１．２ｍｍ，通常状態の内径Ｄ１＝２５ｍｍ，内径Ｄ２＝４０ｍｍ，長手方向の長さが１２０ｍｍに形成されている。この場合、チューブ２１の内周の長さｌは、約７８ｍｍ≦ｌ≦約１２５ｍｍの範囲内で変形可能である。 The faucet connection portion 20 is made of a resin having a wall thickness t of 0.5 mm ≦ t ≦ 3 mm, an inner diameter D1 in a normal state of 15 mm ≦ D1 ≦ 40 mm, and an inner diameter D2 that can be expanded to 17 mm ≦ D2 ≦ 50 mm by elastic deformation. It consists of a tube.
Desirably, the resin tube 21 which is the faucet connection portion 20 has a thickness of 1.2 mm ≦ t ≦ 1.3 mm, an inner diameter D1 in a normal state is 25 mm ≦ D1 ≦ 26 mm, and an inner diameter D2 in an expanded state is 30 mm ≦ D2 ≦ 50 mm.
In the embodiment of the present invention, the tap connection portion 20 is formed, for example, with a thickness t = 1.2 mm, a normal state inner diameter D1 = 25 mm, an inner diameter D2 = 40 mm, and a longitudinal length of 120 mm. . In this case, the length l of the inner periphery of the tube 21 can be deformed within a range of about 78 mm ≦ l ≦ about 125 mm.

また、管体接続部３０は、管体Ｐに挿入される管状の管体挿入部３１と、この管体挿入部３１に連接され蛇口接続部２０であるチューブ２１の通常状態の内径Ｄ１よりも大きな外径を有し、このチューブ２１が取り付けられる管状のチューブ取付部３２とを備えて構成されている。チューブ２１は、チューブ取付部３２に被嵌して取り付けられている。   In addition, the tube connection part 30 has a tubular tube insertion part 31 inserted into the tube P and an inner diameter D1 in a normal state of the tube 21 connected to the tube insertion part 31 and serving as the faucet connection part 20. It has a large outer diameter and is configured to include a tubular tube mounting portion 32 to which the tube 21 is mounted. The tube 21 is fitted and attached to the tube attachment portion 32.

管体挿入部３１は、例えば、金属で形成され、先端側に管体差込部３６を有し、基端側に雄ネジ３４を有して構成されている。管体差込部３６の外周には、複数の凸条３３が列設されている。また、管体挿入部３１の管体差込部３６の外径は、管体Ｐの通常状態の口径以上であって管体Ｐの弾性変形により拡径された口径以下に形成されている。
チューブ取付部３２は、例えば、金属で形成され、管体挿入部３１側の内壁に雄ネジ３４に螺合する雌ネジ３５が形成され、この雄ネジ３４と雌ネジ３５とにより、管体挿入部３１とチューブ取付部３２とは、互いに着脱可能に取り付けられている。 The tubular body insertion portion 31 is formed of, for example, metal, and has a tubular body insertion portion 36 on the distal end side and a male screw 34 on the proximal end side. A plurality of ridges 33 are arranged on the outer periphery of the tubular body insertion portion 36. Further, the outer diameter of the tube insertion portion 36 of the tube insertion portion 31 is not less than the diameter of the tube P in the normal state and not more than the diameter expanded by elastic deformation of the tube P.
The tube attachment portion 32 is formed of, for example, metal, and an internal thread 35 is formed on the inner wall on the tubular body insertion portion 31 side. The internal thread 34 is inserted into the tubular body insertion portion by the external thread 34 and the internal thread 35. The part 31 and the tube attachment part 32 are detachably attached to each other.

また、この蛇口用接続アダプタＡは、蛇口接続部２０を構成するチューブ２１に外挿され、チューブ２１を締め付け及び締め付け解除可能なリングＲを備えている。
このリングＲは、プラスチック等の樹脂で形成され、いずれか一方の面に複数の段部４１が列設される細長状の帯状体４０と、帯状体４０の長手方向のいずれか一方の端部に設けられ帯状体４０が挿通されるとともに帯状体４０の段部４１に爪４３を引っかけて帯状体の抜け止めを行なうストッパ４２とを備えている。
爪４３は、爪４３と一体に形成される凸部４４の押圧により、段部４１への引っかかりを解除することができる。 The faucet connection adapter A includes a ring R that is extrapolated to a tube 21 constituting the faucet connection portion 20 and that can tighten and release the tube 21.
The ring R is formed of a resin such as plastic, and has an elongated belt-like body 40 in which a plurality of step portions 41 are arranged on any one surface, and one end portion in the longitudinal direction of the belt-like body 40. And a stopper 42 for preventing the strip-shaped body from being pulled out by hooking a claw 43 to a step portion 41 of the strip-shaped body 40.
The nail | claw 43 can cancel | release the catch to the step part 41 by the press of the convex part 44 formed integrally with the nail | claw 43. FIG.

管体Ｐが蛇口Ｂに直接取り付けられる場合は、管体Ｐを直接蛇口Ｂに取り付ける一方、管体Ｐを直接蛇口Ｂに取り付けることができない場合には、本発明の実施の形態に係る蛇口用接続アダプタＡを用いる。
管体Ｐを直接取り付けることができない蛇口としては、例えば、図１乃至図３に示す一般家庭用の蛇口Ｂ等がある。
この蛇口Ｂは、流体が送出される送出口１１を有し断面矩形パイプ状の送出管１０と、この送出管１０を操作されて開閉するコック１２とを備えている。
この蛇口Ｂは、断面が矩形でかつ送出管１０の外周が管体Ｐの内径よりも大きく蛇口Ｂに直接取り付けることができない。また、送出口１１に管体Ｐを接続しようとしても、送出口１１は、管体Ｐを接続できるだけの長さがなく、管体Ｐが抜け易くなってしまう。そのため、蛇口用接続アダプタＡを用いて、蛇口Ｂからの流体を効率よく管体Ｐに流すようにする。 When the pipe P is directly attached to the faucet B, the pipe P is attached directly to the faucet B, whereas when the pipe P cannot be directly attached to the faucet B, the faucet according to the embodiment of the present invention is used. Connection adapter A is used.
As a faucet to which the pipe body P cannot be directly attached, for example, there is a general household faucet B shown in FIGS.
The faucet B includes a delivery pipe 10 having a delivery port 11 through which fluid is delivered and having a rectangular cross section, and a cock 12 that is operated to open and close the delivery pipe 10.
The faucet B has a rectangular cross section, and the outer periphery of the delivery pipe 10 is larger than the inner diameter of the pipe body P and cannot be directly attached to the faucet B. Moreover, even if it tries to connect the pipe body P to the delivery port 11, the delivery port 11 does not have the length which can connect the pipe body P, and the pipe body P will become easy to come off. Therefore, the faucet connection adapter A is used to efficiently flow the fluid from the faucet B to the tube P.

従って、本発明の実施の形態に係る蛇口用接続アダプタＡを用いる場合は、予め、管体Ｐの口径に合うように、管体挿入部３１の外径が最適なものを選ぶとともに、使用するチューブ２１の内径に合うようにチューブ取付部３２の外径が最適なものを選び、そして、このチューブ取付部３２に管体挿入部３１を連接する。
それから、管体接続部３０のチューブ取付部３２に蛇口接続部２０としてのチューブ２１を被嵌する。この場合、チューブ２１をチューブ取付部３２に被嵌するだけでよいので、蛇口接続部２０に管体接続部３０を容易に取り付けることができ、構造が簡単なので、コスト安になる。また、チューブ２１が劣化した場合に、交換が容易になる。一方、管体接続部３０においては、管体挿入部３１の管体差込部３６に管体Ｐを差し込む。
この場合、管体Ｐやチューブ２１の径に合わせて、管体挿入部３１とチューブ取付部３２の組み合わせが選択できるので、管体挿入部３１と管体Ｐを密着し易くできる。 Accordingly, when the faucet connection adapter A according to the embodiment of the present invention is used, an adapter having an optimum outer diameter of the tube insertion portion 31 is selected and used in advance so as to match the diameter of the tube P. The tube mounting portion 32 having an optimum outer diameter is selected so as to match the inner diameter of the tube 21, and the tube insertion portion 31 is connected to the tube mounting portion 32.
Then, the tube 21 as the faucet connection portion 20 is fitted on the tube attachment portion 32 of the tube body connection portion 30. In this case, since it is only necessary to fit the tube 21 to the tube attachment portion 32, the tube connection portion 30 can be easily attached to the faucet connection portion 20, and the structure is simple, so the cost is reduced. Moreover, when the tube 21 deteriorates, replacement | exchange becomes easy. On the other hand, in the tube connection part 30, the tube P is inserted into the tube insertion part 36 of the tube insertion part 31.
In this case, since the combination of the tube insertion part 31 and the tube attachment part 32 can be selected according to the diameter of the tube P or the tube 21, the tube insertion part 31 and the tube P can be easily adhered.

次に、図１及び図２に示すように、管体Ｐを取り付けた蛇口用接続アダプタＡにおいて、蛇口接続部２０であるチューブ２１の開口を指等で広げて蛇口Ｂに被嵌する。
詳しくは、蛇口Ｂの送出管１０の先端部の側面下側に設けられた送出口１１がチューブ２１に塞がれないように、当該送出口１１がチューブ２１の内部に位置するとともに、チューブ２１の内壁が送出管１０の外周に密着するようにチューブ２１を蛇口Ｂの送出管１０に被嵌していく。 Next, as shown in FIGS. 1 and 2, in the faucet connection adapter A to which the pipe body P is attached, the opening of the tube 21 that is the faucet connection portion 20 is widened with a finger or the like and fitted into the faucet B.
Specifically, the delivery port 11 is located inside the tube 21 so that the delivery port 11 provided on the lower side of the distal end portion of the delivery tube 10 of the faucet B is not blocked by the tube 21, and the tube 21 The tube 21 is fitted onto the delivery pipe 10 of the faucet B so that the inner wall of the delivery pipe 10 comes into close contact with the outer periphery of the delivery pipe 10.

この際、チューブ２１は、拡径可能で肉厚ｔ＝１．２ｍｍの樹脂製チューブ２１で構成され、比較的薄肉厚なので、少しの力でも拡径させ易くなり、弾性変形による拡径範囲を大きくでき、蛇口Ｂに容易に装着できる。
また、蛇口用接続アダプタＡが比較的薄肉厚なので、弾性変形し易く、そのため、拡径範囲が大きくでき、蛇口Ｂの送出管１０の外径の大きさに対して広い範囲で対応できるようになり、汎用性が向上させられる。
更に、チューブ２１が比較的薄肉厚なので、送出管１０の外側の形状に合わせて変形し易くなり、送出管１０が断面矩形パイプ状であっても、送出管１０の外周に隙間なく密着していき、蛇口接続部２０であるチューブ２１と蛇口Ｂとの密着性が向上させられる。そのため、蛇口Ｂの送出口１１から流体が送出された場合、送出管１０とチューブ２１の間に隙間がなく密着しているので、この部位からの漏水が防止される。 At this time, the tube 21 is made of a resin tube 21 having a wall thickness t = 1.2 mm that can be expanded in diameter, and is relatively thin-walled. It can be enlarged and can be easily attached to the faucet B.
In addition, since the faucet connection adapter A is relatively thin and thick, it is easily elastically deformed, so that the diameter expansion range can be increased and the outer diameter of the delivery pipe 10 of the faucet B can be accommodated in a wide range. Therefore, versatility is improved.
Furthermore, since the tube 21 is relatively thin and thick, the tube 21 is easily deformed in conformity with the outer shape of the delivery pipe 10, and even if the delivery pipe 10 is in the shape of a rectangular pipe, it is in close contact with the outer circumference of the delivery pipe 10 without a gap. As a result, the adhesion between the tube 21 which is the faucet connection portion 20 and the faucet B is improved. Therefore, when the fluid is sent out from the outlet 11 of the faucet B, there is no gap between the delivery pipe 10 and the tube 21, so that water leakage from this part is prevented.

次に、リングＲの帯状体４０をチューブ２１と送出管１０とが密着している箇所に回してストッパ４２に挿通する。そして帯状体４０を引っ張って、チューブ２１を送出管１０とともに締め付ける。   Next, the belt-like body 40 of the ring R is turned to a place where the tube 21 and the delivery pipe 10 are in close contact with each other, and is inserted into the stopper 42. Then, the belt-like body 40 is pulled to tighten the tube 21 together with the delivery pipe 10.

この状態で、蛇口Ｂのコック１２の操作により、送出管１０を開にして送出口１１から流体を送出する。蛇口Ｂの送出口１１から送出された流体は、蛇口接続部２０であるチューブ２１，管体接続部３０を通り、管体Ｐに流される。この際、蛇口Ｂの送出口１１は、蛇口接続部２０であるチューブ２１の内部に位置するとともに、蛇口Ｂの送出管１０の外周はチューブ２１に被せられているので、蛇口Ｂの送出口１１から送出される流体は、蛇口用接続アダプタＡの内部を流れて管体Ｐに到達する。
この際、リングＲでチューブ２１と送出管１０とが締め付けられているので、それだけ、チューブ２１と送出管１０との密着性が向上させられ、送出管１０とチューブ２１の間に隙間ができにくくなり、この点でも、漏水が防止される。 In this state, by operating the cock 12 of the faucet B, the delivery pipe 10 is opened and the fluid is delivered from the delivery port 11. The fluid delivered from the delivery port 11 of the faucet B passes through the tube 21 and the tubular body connection portion 30 which are the faucet connection portion 20 and flows to the tubular body P. At this time, the outlet 11 of the faucet B is located inside the tube 21 that is the faucet connection portion 20, and the outer periphery of the delivery pipe 10 of the faucet B is covered with the tube 21. The fluid delivered from the pipe flows through the faucet connection adapter A and reaches the pipe P.
At this time, since the tube 21 and the delivery pipe 10 are fastened by the ring R, the adhesion between the delivery pipe 10 and the delivery pipe 10 is improved accordingly, and a gap is hardly formed between the delivery pipe 10 and the tubing 21. This also prevents water leakage.

また、管体挿入部３１が、管体Ｐの口径に合わせて交換されているので、管体差込部３６と管体Ｐとが密着しやすくなり、この点でも漏水が防止される。
さらに、管体差込部３６には、凸条３３が列設されているので、内部に流体が流れても、この凸条３３が管体Ｐに引っかかることにより、管体Ｐが管体挿入部３１からはずれにくくなる。 Moreover, since the tube insertion part 31 is replaced | exchanged according to the aperture of the tube P, the tube insertion part 36 and the tube P become easy to closely_contact | adhere, and a water leak is prevented also in this point.
Furthermore, since the protrusion 33 is arranged in the tube insertion part 36, even if a fluid flows inside, this protrusion 33 is caught in the tube P, and the tube P is inserted into the tube. It becomes difficult to remove from the portion 31.

そして次に、この蛇口用接続アダプタＡを蛇口Ｂから取り外す場合は、リングＲの凸部を押圧して爪４３の段部４１への引っかかりを解除して、リングＲの締め付けを解除する。
リングＲは、締め付け及び締め付け解除可能なので、何度も使うことができる。
次に、蛇口接続部２０であるチューブ２１を拡径して蛇口Ｂの送出管１０から取り外す。この際、チューブ２１が比較的薄肉厚なことから拡径し易いので、取り外しが容易にできる。 Next, when removing the faucet connection adapter A from the faucet B, the convex portion of the ring R is pressed to release the hook of the claw 43 from the stepped portion 41 and the tightening of the ring R is released.
Since the ring R can be tightened and untightened, it can be used many times.
Next, the diameter of the tube 21 which is the faucet connection part 20 is expanded and removed from the delivery pipe 10 of the faucet B. At this time, since the tube 21 is relatively thin and thick, it is easy to expand the diameter, so that it can be easily detached.

また、蛇口Ｂのみならず、例えば、図４に示すように、シャワーヘッドＨの場合にも対応できる。
シャワーヘッドＨは、例えば、送出部１０ａに複数の送出口１１ａを有している。この場合にも、上記の蛇口Ｂと同様に、送出口１１ａを塞がないようにシャワーヘッドＨの送出部１０ａにチューブ２１を被せていく。これ以外は上記のものと同様である。 Further, not only the faucet B but also a shower head H as shown in FIG.
The shower head H has, for example, a plurality of delivery ports 11a in the delivery unit 10a. Also in this case, the tube 21 is put on the delivery part 10a of the shower head H so as not to block the delivery port 11a in the same manner as the faucet B described above. The rest is the same as above.

即ち、チューブ２１は比較的薄肉厚で変形が容易なので、一般家庭用の蛇口Ｂの場合、送出部１０の外周の長さＬが７８ｍｍ＜Ｌ＜１２５ｍｍであれば、送出口１１の形状を問わず蛇口用接続アダプタＡを装着できるようになる。また、例えば、シャワーヘッドＨ等のような蛇口Ｂとは異形のものであっても、その外周Ｌ’が７８ｍｍ＜Ｌ’＜１２５ｍｍのものであればこの蛇口用接続アダプタＡを装着できるようになり、汎用性が向上させられる。   That is, since the tube 21 is relatively thin and easily deformed, in the case of a general household faucet B, if the length L of the outer periphery of the delivery unit 10 is 78 mm <L <125 mm, the shape of the delivery port 11 is not limited. It becomes possible to attach the faucet connection adapter A. Further, for example, even if the outer shape L ′ of the faucet B such as the shower head H is 78 mm <L ′ <125 mm, the faucet connection adapter A can be mounted. Therefore, versatility is improved.
