Description

本発明は、水道蛇口に取り付けられ、この水道蛇口にホース、パイプ、散水器具、または水を使用するその他の装置を接続する蛇口接続継手に関する。   The present invention relates to a faucet connection fitting attached to a water tap and connecting the water tap to a hose, a pipe, a watering device, or any other device using water.

図５に示すように、従来の蛇口接続継手２０は、特許文献１のように水道蛇口２１（以下、単に蛇口ともいう）の外周３方向からネジ２２で締め付けて固定することで、蛇口２１に取り付けられるものであった。
また、蛇口２１の先端付近では、蛇口２１の外周を包囲するシール部材２４によって水漏れを防止していた。 As shown in FIG. 5, the conventional faucet connection joint 20 is fixed to the faucet 21 by fastening and fixing it with screws 22 from the outer peripheral 3 direction of the water tap 21 (hereinafter simply referred to as faucet) as in Patent Document 1. It was attached.
In the vicinity of the tip of the faucet 21, the seal member 24 surrounding the outer periphery of the faucet 21 prevents water leakage.

しかし、特許文献１のような蛇口接続継手２０を蛇口２１に取り付ける際には、蛇口２１の先端部分をシール部材２４に差し込んだ後に３本のネジ２２で締め付ける。この際には、蛇口２１とシール部材２４との間に隙間が生じて水漏れが起こるのを防止するために、目視でネジ２２の締め付け量を確認しながら均等に締め付けていく必要があり、手間がかかっていた。
また、３本のネジ２２，２２，２２は放射状に配置されているため、このうち数本のネジ２２が蛇口２１の配管や壁の近くに突出することが多く、工具を隙間に差し込んでネジ２２を締め付ける作業が難しかった。 However, when attaching the faucet connection joint 20 like patent document 1 to the faucet 21, after the front-end | tip part of the faucet 21 is inserted in the sealing member 24, it tightens with three screws 22. FIG. At this time, in order to prevent a gap from occurring between the faucet 21 and the sealing member 24 and causing a water leak, it is necessary to check the amount of tightening of the screw 22 visually and uniformly tightening. It took time and effort.
In addition, since the three screws 22, 22 and 22 are arranged radially, several of these screws 22 often protrude near the piping or wall of the faucet 21, and the tool is inserted into the gap to be screwed. The work to tighten 22 was difficult.

特許文献２には、放射状に配置された３本のネジにそれぞれ取り付けたピニオンと、継手本体の外周を取り囲むとともにこれらのピニオンに噛み合う環状クラウン歯車とを用いて３本のネジを連結し、１本のネジの回動操作に残りの２本も連動させて、蛇口に固定することができる蛇口接続継手が記載されている。   In Patent Document 2, three screws are connected using pinions respectively attached to three radially arranged screws, and an annular crown gear that surrounds the outer periphery of the joint body and is engaged with these pinions; A faucet connection joint is described which can be locked to a faucet by interlocking the remaining two with the turning operation of a book screw.

しかし、この蛇口接続継手では、３本のネジ、３つのピニオン、一対の環状クラウン歯車が必要となるため、部品点数が多く、また、形状の精度や強度も必要になるため、製造コストが大きくなってしまっていた。   However, since this faucet connection joint requires three screws, three pinions, and a pair of annular crown gears, the number of parts is large and the shape accuracy and strength are also required, so the manufacturing cost is large. It had become.

また、特許文献１，２の蛇口接続継手では、図５（ｂ）に示すようにネジ２２を取り付けた高さの継手本体２３の中心と、シール部材２４の中心とは上下方向の一直線上に並んでいる。
これに対し、水道蛇口２１には、先端部分から近い位置で垂直に湾曲しているものが少なくない。
そのため、特許文献１，２の蛇口接続継手２０では、蛇口２１の湾曲している部分をネジ２２で固定し、ネジ２２の高さで蛇口２１の中心と継手本体２３の中心とを一致させると、シール部材２４の高さでは蛇口２１の中心とシール部材２４（継手本体２３）の中心とにずれが生じ、蛇口２１とシール部材２４との間に隙間が生じて水漏れが起こる可能性があった。
また、シール部材２４の一部に蛇口２１からの負荷が偏るため、シール部材２４や継手本体２３が破損するおそれがあった。
この場合、継手本体２３の吐水口の向きが蛇口２１に対して傾いてしまうため、他の装置を取り付けずに水を出す場合、吐水方向が変わってしまっていた。 Moreover, in the faucet connection joint of patent documents 1, 2, as shown in FIG.5 (b), the center of the joint main body 23 of the height which attached the screw 22, and the center of the sealing member 24 are on a straight line on an up-down direction. Lined up.
On the other hand, there are not many water taps 21 that are vertically curved at a position near the tip.
Therefore, in the faucet connection joint 20 of Patent Documents 1 and 2, the curved portion of the faucet 21 is fixed by the screw 22, and the center of the faucet 21 and the center of the joint main body 23 coincide with each other at the height of the screw 22. At the height of the seal member 24, the center of the faucet 21 and the center of the seal member 24 (the joint main body 23) are displaced, and a gap may be generated between the faucet 21 and the seal member 24 to cause water leakage. there were.
Moreover, since the load from the faucet 21 is biased to a part of the seal member 24, there is a possibility that the seal member 24 and the joint body 23 may be damaged.
In this case, since the direction of the spout of the joint body 23 is inclined with respect to the faucet 21, the direction of spouting has been changed when water is discharged without attaching another device.

特許文献１の蛇口接続継手２０で、シール部材２４の中心と蛇口２１の中心とを合わせ、かつネジ２２によって蛇口２１を強固に固定するためには、ネジ２２の位置で継手本体２３の中心と蛇口２１の中心とをずらし、３本のネジ２２，２２，２２の締め込み量を各別に変更して調整するなど、面倒な作業が必要になっていた。   In order to align the center of the seal member 24 with the center of the faucet 21 and firmly fix the faucet 21 by the screw 22 with the faucet connection joint 20 of Patent Document 1, the center of the joint body 23 at the position of the screw 22 It is necessary to perform troublesome work such as shifting the center of the faucet 21 and changing and adjusting the tightening amount of the three screws 22, 22 and 22 separately.

図１（ｂ）に示すように、シール部材１１は、弾性材料から形成される略円形の部材であり、蛇口２を内接させるために円形の開口を中心に形成している。この開口の径は、蛇口２からの水漏れを防止できるように、蛇口の外径と同等かやや小さく設定されている。
シール部材１１の材料には、ＮＢＲ（ニトリルゴム）、ＥＰＤＭ（エチレン、プロピレン、ジエンゴム）、シリコン、フッ素等を使用することができる。この中でも、耐塩素性に優れるＥＰＤＭが好ましく、ＥＰＤＭの中でも水密性に優れる硬度６０°のものが特に好ましい。
シール部材１１は、外周縁をナット部材５とニップル６との間に挟み込まれることにより、継手本体３に固定される。 As shown in FIG. 1 (b), the seal member 11 is a substantially circular member formed of an elastic material, and is formed around a circular opening in order to internally contact the faucet 2. The diameter of the opening is set to be equal to or slightly smaller than the outer diameter of the faucet so as to prevent water leakage from the faucet 2.
As a material of the seal member 11, NBR (nitrile rubber), EPDM (ethylene, propylene, diene rubber), silicon, fluorine or the like can be used. Among these, EPDM which is excellent in chlorine resistance is preferable, and among the EPDMs, one having a hardness of 60 ° which is excellent in water tightness is particularly preferable.
The seal member 11 is fixed to the joint body 3 by holding the outer peripheral edge between the nut member 5 and the nipple 6.

蛇口接続継手１は、図１（ｂ）に示すように、継手本体３を蛇口２に固定するための蛇口締め付け部材１２を有している。
図３に示すように、蛇口締め付け部材１２は、リング１３と、ツメ部材１４と、ビス１５とを組み立ててなる。
リング１３は、環状の部品であって、周上の対向する位置に、ツメ部材１４を取り付けるための孔と、ビス１５を取り付けるために雌ネジを形成した孔とをそれぞれ穿設している。
リング１３の内径は、蛇口の外径よりも相当程度大きく設定されている。
リング１３の材料には、金属や樹脂を用いることができる。その中でも剛性に優れる金属を用いるのが好ましく、金属の中でも耐腐食性に優れるステンレスが特に好ましい。 The faucet connection joint 1 has a faucet tightening member 12 for fixing the joint body 3 to the faucet 2, as shown in FIG. 1 (b).
As shown in FIG. 3, the faucet tightening member 12 is formed by assembling the ring 13, the claw member 14 and the screw 15.
The ring 13 is an annular component, and has holes for attaching the claw members 14 and holes for forming the female screws for attaching the screws 15 at opposite positions on the circumference.
The inner diameter of the ring 13 is set to be considerably larger than the outer diameter of the faucet.
A metal or resin can be used as the material of the ring 13. Among them, it is preferable to use a metal excellent in rigidity, and among metals, stainless steel excellent in corrosion resistance is particularly preferable.

ツメ部材１４は、リング１３から内側に突出するように固定される。ツメ部材１４の先端は、蛇口２を強く挟持できるように、断面三角形状に形成されている。
ツメ部材１４の材料には、金属や樹脂を用いることができる。その中でも剛性に優れる金属を用いるのが好ましく、金属の中でも耐腐食性に優れるステンレスが特に好ましい。
なお、ツメ部材１４は一体成形などにより最初からリング１３と一体に形成してもよい。 The claw member 14 is fixed so as to protrude inward from the ring 13. The tip end of the claw member 14 is formed in a triangular shape in cross section so that the faucet 2 can be firmly held.
For the material of the claw member 14, metal or resin can be used. Among them, it is preferable to use a metal excellent in rigidity, and among metals, stainless steel excellent in corrosion resistance is particularly preferable.
The claw member 14 may be formed integrally with the ring 13 from the beginning by integral molding or the like.

ビス１５は、棒状の部材であって、リング１３に取り付けられる端部には雄ネジ１６が形成されている。他方、蓋部材４を貫通して継手本体３の外側に突出する端部には、操作用のハンドル１７が取り付けられている。
これにより、ビス１５はネジ結合によってリング１３に取り付けられ、リング１３の中心およびツメ部材１４に向かって所定範囲で接近離間可能に保持される。
ビス１５の材料には、金属や樹脂を用いることができる。その中でも剛性に優れる金属を用いるのが好ましく、金属の中でも耐腐食性に優れるステンレスが特に好ましい。 The screw 15 is a rod-like member, and an external thread 16 is formed at an end attached to the ring 13. On the other hand, a handle 17 for operation is attached to an end portion which penetrates the lid member 4 and protrudes to the outside of the joint body 3.
Thereby, the screw 15 is attached to the ring 13 by screw connection, and is held so as to be able to approach and separate in a predetermined range toward the center of the ring 13 and the claw member 14.
Metal and resin can be used for the material of the screw 15. Among them, it is preferable to use a metal excellent in rigidity, and among metals, stainless steel excellent in corrosion resistance is particularly preferable.

図２（ｃ）に示すように、蛇口接続継手１の組み立て後には、蓋部材４とナット部材５との間（蓋部材４の円筒部分の内部）に空間Ｓが形成され、蛇口締め付け部材１２はこの空間Ｓ内に配置される。
この空間は略円形で、リング１３の外径よりも大きい径を有するため、蛇口締め付け部材１２はこの空間Ｓにおいて水平面（上下方向に直交する平面）内の任意の方向に揺動可能である。したがって、シール部材１１の中心に対して、蛇口締め付け部材１２の中心を真上に位置させて一致させることもでき（図１（ｂ））、また、偏心させることもできる（図２（ｂ））。 As shown in FIG. 2C, after the faucet connection joint 1 is assembled, a space S is formed between the lid 4 and the nut 5 (inside the cylindrical portion of the lid 4), and the faucet clamp 12 Are arranged in this space S.
Since this space is substantially circular and has a diameter larger than the outer diameter of the ring 13, the faucet tightening member 12 can be swung in any direction in the horizontal plane (a plane orthogonal to the vertical direction) in the space S. Therefore, with respect to the center of the sealing member 11, the center of the faucet tightening member 12 can be positioned directly above and in line (FIG. 1 (b)) or can be eccentric (FIG. 2 (b)). ).

蛇口の湾曲はＲ（曲率半径）１００ｍｍ程度（蛇口の直径はφ１６ｍｍ程度）であることが多い。
このＲに対応するため、蛇口締め付け部材１２の遊動可能範囲を０．５ｍｍ以上とするのが好ましい。さらに、Ｒ１００ｍｍの蛇口が曲げ加工時につぶれたり、メッキ加工前の研磨工程で削れたりした場合にも対応できるように、蛇口締め付け部材１２の遊動可能範囲を１．５ｍｍ以上とするのがより好ましい。 The curvature of the faucet is often about R (curvature radius) of about 100 mm (the diameter of the faucet is about φ16 mm).
In order to correspond to this R, it is preferable to make the movable range of the faucet tightening member 12 0.5 mm or more. Furthermore, it is more preferable that the movable range of the faucet tightening member 12 be 1.5 mm or more so that the faucet of R100 mm can be coped with when it crushes in bending or is scraped in the polishing process before plating.

蛇口締め付け部材１２の遊動可能範囲を大きくすると、蛇口接続継手１を蛇口２に取り付ける時に蛇口２がガタつくおそれがあるが、シール部材１１の厚みを厚くすることで、蛇口２のガタつきを防止することができる。   There is a possibility that the faucet 2 may rattle when attaching the faucet connection joint 1 to the faucet 2 if the movable range of the faucet tightening member 12 is enlarged, but the thickness of the sealing member 11 is increased to prevent the faucet 2 from rattling can do.

この蛇口接続継手１に蛇口２を取り付けるには、まずハンドル１７を回転させ、ビス１５の締め込み量を充分に浅くしてから、蛇口２を継手本体３に差し込む。
シール部材１１の弾性変形によって蛇口２の外周が包囲されたら、ハンドル１７を回転させてビス１５を締め込むことにより、蛇口２をビス１５とツメ部材１４とで挟み込んで固定する。 In order to attach the faucet 2 to the faucet connection joint 1, first, the handle 17 is rotated to make the tightening amount of the screw 15 sufficiently shallow, and then the faucet 2 is inserted into the joint body 3.
When the outer periphery of the faucet 2 is surrounded by the elastic deformation of the sealing member 11, the faucet 2 is sandwiched and fixed by the screw 15 and the claw member 14 by rotating the handle 17 and tightening the screw 15.

蛇口２から蛇口接続継手１を取り外す際には、ハンドル１７を操作してビス１５の締め込みを緩め、継手本体３を蛇口２から引き抜けばよい。   When removing the faucet connection joint 1 from the faucet 2, the handle 17 may be operated to loosen the screw 15 and the joint body 3 may be pulled out of the faucet 2.

この蛇口接続継手１では、蛇口締め付け部材１２がシール部材１１に対して偏心できるように、少なくとも一直線方向に遊動可能であることにより、図１のように直線的な形状の蛇口２だけでなく、図２のように湾曲している蛇口２に対しても容易かつ確実に取り付けることができる。
このとき、図２（ｂ）に示すように、蛇口締め付け部材１２の中心とその高さでの蛇口２の中心とが一致するため、蛇口接続継手１を蛇口２に強固に固定することができる。
また、シール部材１１の中心とその高さでの蛇口２の中心とが一致するため、シール部材１１が蛇口２の外周を隙間なく包囲して水漏れを防止することができるとともに、負荷の偏りによってシール部材１１が破損することがない。
さらに、このとき、継手本体３（ニップル６）の吐水方向が蛇口２の向きから変わってしまうことがない。 In this faucet connection joint 1, not only the faucet 2 having a linear shape as shown in FIG. 1, but also by being movable in at least one linear direction so that the faucet tightening member 12 can be eccentric with respect to the sealing member 11 It can attach easily and certainly also to the faucet 2 curved like FIG.
At this time, as shown in FIG. 2 (b), the center of the faucet tightening member 12 and the center of the faucet 2 at the height thereof coincide with each other, so the faucet connection joint 1 can be firmly fixed to the faucet 2 .
In addition, since the center of the seal member 11 coincides with the center of the faucet 2 at that height, the seal member 11 can surround the outer periphery of the faucet 2 without a gap to prevent water leakage and bias of load As a result, the seal member 11 is not damaged.
Furthermore, at this time, the water discharge direction of the joint body 3 (nipple 6) does not change from the direction of the faucet 2.

また、蛇口締め付け部材１２がシール部材１１に対して少なくとも一直線方向に遊動可能であることにより、蛇口２と２箇所のみで当接する簡素な蛇口締め付け部材１２であっても、ビス１５を締め付ける間にリング１３が自動的に最適な位置まで遊動するため、蛇口２に強固に固定することができる。
さらに、１つのビス１５で蛇口２を締め付ける簡素な蛇口締め付け部材１２としたことにより、１つのビス１５を操作するだけで容易に蛇口に取り付けることができる。また、簡素な部品形状であるとともに部品点数が少ないため、製造コストを低減させることができる。 In addition, the faucet fastening member 12 can move in the at least one linear direction with respect to the sealing member 11 so that the simple faucet fastening member 12 coming into contact with the faucet 2 only at two places can Since the ring 13 automatically floats to the optimum position, it can be firmly fixed to the faucet 2.
Furthermore, the simple faucet fastening member 12 in which the faucet 2 is fastened with one screw 15 can be easily attached to the faucet simply by operating the one screw 15. In addition, since the shape of parts is simple and the number of parts is small, the manufacturing cost can be reduced.

さらに、図２（ｃ）に示すように、蛇口締め付け部材１２が水平面内の任意の方向に揺動可能であることにより、一直線方向にのみ揺動可能である場合に比べて、蛇口２に取り付ける際に蛇口２の湾曲の方向と蛇口締め付け部材１２の揺動の方向とを合わせるなどの手間をかける必要がなく、様々な形状の蛇口２に容易に取り付けることができる。   Furthermore, as shown in FIG. 2 (c), the faucet tightening member 12 is attached to the faucet 2 as compared with the case where it can be swung only in a straight line direction by being able to swing in any direction in the horizontal plane. There is no need to take time and effort to match the direction of curvature of the faucet 2 with the direction of swinging of the faucet tightening member 12, and the faucet 2 can be easily attached to various shapes.

第一実施形態ではツメ部材１４の個数は１つであったが、ツメ部材１４を２つ以上設けてもよい。
この場合には、ツメ部材１４の配置は特に限定されないが、蛇口２をバランスよく保持するため、放射状すなわちリング１３の周上等間隔に配置するのが好ましい。 Although the number of the claw members 14 is one in the first embodiment, two or more claw members 14 may be provided.
In this case, the arrangement of the claw members 14 is not particularly limited, but in order to keep the faucet 2 in a well-balanced manner, it is preferable to arrange them radially or at equal intervals on the circumference of the ring 13.

＜第二実施形態＞
第一実施形態の蛇口締め付け部材１２にはリング１３を設けたが、この部品の形状は環状には限られない。
第一実施形態のリング１３の代わりに、図４（ｃ）に示すように、第二実施形態ではＣ字フレーム１８を用いている。Ｃ字フレーム１８は、環状の部品の円周のおよそ４分の１を切り欠いた平面視略Ｃ字形状に形成されている。
Ｃ字フレーム１８の両端付近の対向する位置には、ツメ部材１４とビス１５とがそれぞれ取り付けられる。
また、蓋部材４においても、Ｃ字フレーム１８の切り欠きに相当する位置に凹みを設けておく。 Second Embodiment
Although the faucet tightening member 12 of the first embodiment is provided with the ring 13, the shape of this part is not limited to an annular shape.
As shown in FIG. 4C, a C-shaped frame 18 is used in the second embodiment instead of the ring 13 in the first embodiment. The C-shaped frame 18 is formed in a substantially C-shape in a plan view in which about a quarter of the circumference of the annular part is cut away.
The claw members 14 and the screws 15 are attached to opposing positions near the both ends of the C-shaped frame 18 respectively.
Further, also in the lid member 4, a recess is provided at a position corresponding to the notch of the C-shaped frame 18.

図４（ａ）（ｂ）に示すように、第二実施形態の蛇口接続継手１は、Ｃ字フレーム１８を用いたことにより、先端付近で急に湾曲している蛇口２にも取り付けることができる。
この蛇口接続継手１は、Ｃ字フレーム１８の切り欠きおよび蓋部材４の凹みの向きを、蛇口２の湾曲している基端側に合わせて、蛇口２に取り付ける。
これにより、蛇口２の基端側の部分が蓋部材４にぶつかることを防止し、蛇口２先端がシール部材１１に包囲されるまで深く差し込んで、蛇口接続継手１を確実に蛇口に取り付けることができる。
なお、図４（ｂ）では、Ｃ字フレーム１８が空間Ｓ内で図中左右方向に動ける距離はわずかであるが、実際には蛇口２の湾曲に対応するため遊動するのに充分な隙間が存在する。 As shown in FIGS. 4 (a) and 4 (b), the faucet connection joint 1 of the second embodiment can also be attached to the faucet 2 that is sharply curved near the tip by using the C-shaped frame 18. it can.
The faucet connection joint 1 is attached to the faucet 2 in such a manner that the direction of the notch of the C-shaped frame 18 and the recess of the lid member 4 is aligned with the curved proximal end of the faucet 2.
This prevents the proximal end portion of the faucet 2 from hitting the lid member 4, and the faucet connection joint 1 is securely attached to the faucet by deeply inserting the tip of the faucet 2 until it is surrounded by the sealing member 11. it can.
In FIG. 4 (b), although the distance in which the C-shaped frame 18 can move in the space S in the lateral direction in the space S is small, the gap is sufficient to move in order to correspond to the curvature of the faucet 2 in practice. Exists.
