Description

【０００１】
【発明の属する技術分野】
本発明は、台所、洗面台及び多目的な洗い場などに設置する水栓金具の回転取付構造に関するものである。
【０００２】
【従来の技術】
従来の水栓の一種として、先端に吐水具を接続したホースを内蔵する水栓がある。このホースは水栓本体から引き出すことができ、また水栓本体が上下方向に移動可能な構造を有した水栓であり、洗面器設置部の上面に構成されるカウンターの平坦部や傾斜部に設置されるのが一般的である。
例えばその取付構造は、雄ねじ部を有した水栓本体を取付け面に設けた穴に挿通して、取付け面の裏側から固定ナットで該雄ねじ部に螺着して取付けるものであった。このような取付構造では、水栓本体と取付け面を完全固定することになり、水栓本体を取付け面に対して回転させることができない為、水栓の吐水位置を回転して変えるような場合には、回転機構部を水栓本体に別途設ける必要があり、水栓本体のサイズが大きくなるという問題があり、又意匠的にも水栓本体部と回転部に継ぎ目が見えて好ましくない。（例えば、特許文献１参照。）

【発明が解決しようとする課題】
本発明が解決しようとする課題は、台所、洗面台、及び多目的な洗い場などに取付けたパネルに水栓を取付ける場合に、水栓を取付け面に取付ける機構を水栓が回転可能な構造で同時に水栓をパネルに保持する機構とし、さらに水栓の回転規制をすることができる保持機構であって、組立て作業を容易、迅速にできることを提供することにある。
【０００５】
【課題を解決するための手段】
第１の発明では、シャワーホースを挿通できる筒状の水栓を壁面又は洗面器に取付けたパネルに固定する構造において、該パネルに設けた水栓取付孔に挿通され該パネル裏面後方に突出する部位が略半円筒状であり、該略半円筒状の外全周部に凹部が設けられ、該凹部下面とパネル裏面が略同一平面上に取付けられる挿通部を有した水栓であって、該パネルの裏側から水栓取付孔周縁に密着して該水栓の挿通部に設けられた凹部に、略該凹部径の略半環状の固定具を嵌合するとともに該固定具を該パネル裏面に固定させて、該水栓を垂直方向に保持し、且つ回転可能としたことを特徴とする。
【０００６】
本発明によれば、一部材でパネルに水栓を保持して且つ水栓がパネルに対して回転可能な構造となるため、パネルと水栓の接合部が同時に水栓の回転基面となり、わざわざ回転機構部を水栓本体に設ける必要がないため、水栓本体をコンパクトにでき、意匠的にも継ぎ目の無いすっきりした水栓本体とすることができる。また、パネルへの水栓の取付、組立て作業を容易、且つ迅速に行うことができる。
【０００７】
第２の発明では、前記水栓の略半円筒状の外周方向に突起部を設け、該突起部をパネルの水栓取付孔周縁裏面に設けた突起部と当接させて該水栓の回転を規制することを特徴とする。
【０００８】
本発明によれば、水栓の過回転による洗面器外への水の飛出しを防止できる。
【０００９】
第３の発明では、前記水栓と嵌合された該固定具の略半環状の内周方向に突起部を設け、該水栓の略半円筒状の端部と当接させて該水栓の回転を規制することを特徴とする。
【００１０】
本発明によれば、水栓の過回転による洗面器外への水の飛出しを防止できる。
【００１１】
第４の発明では、前記水栓の略半円筒状の外周面に半円状の凹部を等間隔に複数個設け、該水栓が回転した時に該水栓の略半円筒状の外周面と該半円状の凹部に常時当接する板ばね装着部を設けた固定具として、該水栓回転時にクリック感覚を有することを特徴とする。
【００１２】
本発明によれば、水栓を回転させる際の良好な操作感覚を得ることができ、回転途中の位置決めもし易くなる。
【００１３】
第５の発明では、前記水栓の略半円筒状の上面に板ばね装着部を設け、該水栓の略半円筒状の凹部に嵌合された固定具の外周面に半円状の凹部を等間隔に複数個設け、該水栓が回転した時に該板ばね装着部と該固定具の凹部を当接させて、該水栓回転時にクリック感覚を有することを特徴とする。
【００１４】
本発明によれば、第４の発明の実施形態の代替手段であり、水栓を回転させる際の良好な操作感覚を得ることができ、回転途中の位置決めもし易くなる。
【００１５】
【発明の実施の形態】
以下に図面を参照して本発明をより具体的に説明する。
図１は本発明にかかわる水栓金具の全体外観図であり、図２は図１におけるＡ−Ａ部分断面図である。
水栓金具21は吐水具22を支持する支持管23と、該支持管23を水栓パネル24の水栓挿通孔に保持する固定具25と、さらに水封を目的としたパッキン26から構成される。
給水側に接続されたホース27が、支持管23の内部空洞を通り、その先端に吐水具22が接続されている。
吐水具22は支持管23に対して着脱可能であり、ホース27を介して支持管23から引き出して使用することができる。
【００１６】
次に支持管23の水栓パネル24への取付け方法を説明する。
図３に示すように支持管23は、水栓パネル24の水栓挿通孔よりも大きな形状を有した根元部31と該挿通孔の隙間をシールするＯリング装着部34と、該装着部34の上方に半円筒形状で水栓挿通孔よりも小さな径の凹部32を有した突起部35を設けている。なお、図３の（Ｂ）は図３の（Ａ）におけるＢ−Ｂ部分断面図である。半円筒形状とするのは、図２及び図１１に示すように支持管23が水栓パネル24の傾斜面に取付けられた場合、半円筒形状部以外の領域でホースが容易に摺動し易いような通路を確保する為である。
【００１７】
支持管23を水栓パネル24の水栓挿通孔に表側から挿入していくと、図３に示すように支持管23の根元部31が水栓パネル24に当接する。これが支持管23の挿入方向の位置決めとなる。この時、支持管23の凹部32の下端面32aと水栓パネル24の裏面24aが概ね面一となり、Ｏリング装着部34が水栓挿通孔内にくるように設定されている。この状態において、支持管23の凹部32に図４に示すような円弧状の固定具25を水栓パネル24の裏側から嵌め込むことにより、支持管23が水栓パネル24へ保持される。もちろん、支持管23が水栓パネル24に保持される為には、固定具25は支持管23の凹部32に概ね当接する円弧内径を有し、且つ円弧外径は水栓挿通孔よりも大きな径であることが必要である。固定具25との引っ掛かり代となる支持管23の凹部代は少なくとも１ｍｍ以上となることが望ましい。
【００１８】
この固定具25の嵌め込み方法としては固定具25を両開きにして挟み込むものである。例えば、図４に示すように固定具25の回転支点部42をポリアセタール等の樹脂で弾性変形可能な円弧形状とし、図６に示すように回転支点部42を中心として左右に開いた状態で水栓パネル24裏面に設けた突起部33と支持管23の凹部32の間に挟み込むように外周上方向から該凹部32に沿わせるように当接させる。その後に水栓パネル24と固定具25を固定する。この固定方法は、固定具25の円弧端部を鍵形状41にしてこれと嵌合可能な形状をした突起51に係止めさせればよい。このように固定具25を水栓パネル24に固定し、且つ支持管23が自由に回転可能な状態で支持管23の凹部32に介在させることで、支持管23の保持・回転が可能な構造をとることができる。
【００１９】
また、点検、修理等で支持管25を水栓パネル24から取外す場合は、鍵形状41の反対側に設けたレバー部43を固定具25の円弧中心方向に押せばよい。その反作用で鍵形状部41が反対の半径外方向へ押しだされ突起51への引っ掛かりが外れて支持管25の取外しが可能となる。
【００２０】
このような係止め構造は、工具を使わずに水栓パネル24に支持管23を固定することができるので、組立て作業を容易かつ迅速に行うことができる。また、鍵形状以外の係止め方法を図7に示す。水栓パネル71にボス72を設け、固定具73にねじ固定用穴部74を設け、これを該ボス72にねじで固定するものである。
【００２１】
基本的な保持・回転機構は以上であるが、付加機能として図６に示すように、固定具25に板ばね装着部44を設けて支持管回転時のクリック機能をもたせることもできる。該板ばね装着部44に板ばね45を設置し、支持管23の凹部32に数個設けた半円状の凹部61と該板ばね45を当接させることで支持管23の回転の際に板ばね45の弾性力で凸凹形状を通過してクリック感を得ることができる。逆に、図８、図９に示すように支持管81に板ばねの装着部82を設け、凸凹形状を固定具91の円弧形状外周部92に設けても同様にクリック感を得ることができる。
【００２２】
図１０に支持管81が0度、90度位置での状態を示す。支持管81には水栓挿通孔よりも大きくなるような突起部83を半円筒形状の端部に設け、該支持管81と嵌合させる固定具91には、図９に示すように円弧中心側へ突き出した突起部93を設ける。該支持管81と該固定具91を上記方法で組み合わせた場合、支持管81を0度位置から90度方向に回転させると支持管81の突起部端面83aと固定具91の突起部93とが当接して90度位置で回転を止めることができる。
【００２３】
支持管81を水栓挿通孔に挿入する際に、該支持管81の突起部83は水栓挿通孔よりも大きいので、そのまま水栓取付軸と支持管81の取付軸と平行に挿入すると物理的に突起部83が引っかかり挿入できない。そこで、図１２に示すように支持管81の挿通部形状を半円筒状としている。水栓取付軸と傾けて挿入することで水栓挿通孔よりも一部大きな突起部があっても挿入可能となる。
【００２４】
また、支持管81を90度位置から0度方向に回転させると、支持管81の突起部83が水栓パネル24の突起部33と当接して0度の位置で回転を止めることができる。
【００２５】
最後に、図１０に示しているカバー101については、吐水具22を引き出してホース27を摺動させる場合に、ホース27が支持管81や水栓パネル24と接触して摩擦を生じる場合に用いるとよい。支持管81や水栓パネル24の材料としてはＡＢＳ樹脂が多く用いられ耐摩耗性に劣る。従って耐摩耗性に優れた材料、例えばポリアセタールで作られたカバー101を摩擦箇所に使用すれば摩擦による部品の劣化を軽減でき、更に部品段差等によりホース27がうまく摺動できない場合のガイド役としても効果が期待できる。該カバー101は、固定具73のねじ固定用穴74と一緒に水栓パネルのボス72にねじ止めすることができる。
【００２６】
【発明の効果】
本発明では、上記構成をとることにより、以下に示す効果を奏する
第１の発明では、シャワーホースを挿通できる筒状の水栓を壁面又は洗面器に取付けたパネルに固定する構造において、該パネルに設けた水栓取付孔に挿通され該パネル裏面後方に突出する部位が略半円筒状であり、該略半円筒状の外全周部に凹部が設けられ、該凹部下面とパネル裏面が略同一平面上に取付けられる挿通部を有した水栓であって、該パネルの裏側から水栓取付孔周縁に密着して該水栓の挿通部に設けられた凹部に、略該凹部径の略半環状の固定具を嵌合するとともに該固定具を該パネル裏面に固定させて、該水栓を垂直方向に保持し、且つ回転可能としたことを特徴とする。
これにより、一部材でパネルに水栓を保持して且つ水栓がパネルに対して回転可能な構造となるため、パネルと水栓の接合部が同時に水栓の回転基面となり、わざわざ回転機構部を水栓本体に設ける必要がないため、水栓本体をコンパクトにでき、意匠的にも継ぎ目の無いすっきりした水栓本体とすることができる。また、パネルへの水栓の取付、組立て作業を容易、且つ迅速に行うことができる。第２の発明では、前記水栓の略半円筒状の外周方向に突起部を設け、該突起部をパネルの水栓取付孔周縁裏面に設けた突起部と当接させて該水栓の回転を規制することを特徴とする。
これにより、水栓の過回転による洗面器外への水の飛出しを防止できる。

[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is an overall external view of a faucet fitting according to the present invention, and FIG. 2 is a partial sectional view taken along line AA in FIG.
The faucet fitting 21 is composed of a support tube 23 that supports the water discharger 22, a fixture 25 that holds the support tube 23 in the faucet insertion hole of the faucet panel 24, and a packing 26 for water sealing purposes. The
A hose 27 connected to the water supply side passes through the internal cavity of the support tube 23, and a water discharger 22 is connected to the tip thereof.
The water discharger 22 can be attached to and detached from the support tube 23, and can be used by being pulled out from the support tube 23 via the hose 27.
[0016]
Next, a method for attaching the support tube 23 to the faucet panel 24 will be described.
As shown in FIG. 3, the support tube 23 includes a root portion 31 having a shape larger than the faucet insertion hole of the faucet panel 24, an O-ring attachment portion 34 that seals a gap between the insertion holes, and the attachment portion 34. A projection 35 having a recess 32 having a semi-cylindrical shape and a diameter smaller than that of the faucet insertion hole is provided on the upper side. 3B is a partial cross-sectional view taken along the line BB in FIG. 2 and 11, when the support tube 23 is attached to the inclined surface of the faucet panel 24, the hose easily slides in a region other than the semi-cylindrical portion. This is to secure such a passage.
[0017]
When the support tube 23 is inserted into the faucet insertion hole of the faucet panel 24 from the front side, the root portion 31 of the support tube 23 contacts the faucet panel 24 as shown in FIG. This is the positioning of the support tube 23 in the insertion direction. At this time, the lower end surface 32a of the recess 32 of the support tube 23 and the back surface 24a of the faucet panel 24 are substantially flush with each other, and the O-ring mounting portion 34 is set in the faucet insertion hole. In this state, the support tube 23 is held on the faucet panel 24 by fitting an arcuate fixture 25 as shown in FIG. 4 into the recess 32 of the support tube 23 from the back side of the faucet panel 24. Of course, in order for the support tube 23 to be held by the faucet panel 24, the fixture 25 has an arc inner diameter that substantially abuts against the recess 32 of the support tube 23, and the arc outer diameter is larger than the faucet insertion hole. It must be a diameter. It is desirable that the recess margin of the support tube 23 that becomes a catch margin with the fixture 25 is at least 1 mm or more.
[0018]
As a method of fitting the fixing tool 25, the fixing tool 25 is double-opened and sandwiched. For example, as shown in FIG. 4, the rotation fulcrum portion 42 of the fixture 25 has an arc shape that can be elastically deformed with a resin such as polyacetal, and the water is opened left and right around the rotation fulcrum portion 42 as shown in FIG. It is made to contact | abut so that it may follow along the said recessed part 32 from the outer periphery upper direction so that it may pinch | interpose between the projection part 33 provided in the plug panel 24 back surface, and the recessed part 32 of the support tube 23. FIG. Thereafter, the faucet panel 24 and the fixture 25 are fixed. In this fixing method, the arc end portion of the fixture 25 may be locked with a protrusion 51 having a key shape 41 and a shape that can be fitted thereto. In this way, the fixing tool 25 is fixed to the faucet panel 24, and the support tube 23 can be held and rotated by being interposed in the recess 32 of the support tube 23 with the support tube 23 being freely rotatable. Can be taken.
[0019]
Further, when the support tube 25 is removed from the faucet panel 24 for inspection, repair, etc., the lever portion 43 provided on the opposite side of the key shape 41 may be pushed toward the center of the arc of the fixture 25. As a result of the reaction, the key-shaped portion 41 is pushed outward in the opposite radius, and the hook to the projection 51 is released, so that the support tube 25 can be removed.
[0020]
Such a locking structure can fix the support tube 23 to the faucet panel 24 without using a tool, so that the assembling work can be performed easily and quickly. FIG. 7 shows a locking method other than the key shape. The faucet panel 71 is provided with a boss 72, the fixture 73 is provided with a screw fixing hole 74, and this is fixed to the boss 72 with a screw.
[0021]
Although the basic holding / rotating mechanism is as described above, as shown in FIG. 6, as an additional function, a plate spring mounting portion 44 can be provided on the fixture 25 to provide a click function when the support tube is rotated. A leaf spring 45 is installed in the leaf spring mounting portion 44, and the leaf spring 45 is brought into contact with several semicircular recesses 61 provided in the recess 32 of the support tube 23, so that the support tube 23 is rotated. A click feeling can be obtained by passing through the uneven shape by the elastic force of the leaf spring 45. On the contrary, as shown in FIGS. 8 and 9, the click feeling can be similarly obtained by providing the support tube 81 with the leaf spring mounting portion 82 and providing the uneven shape on the arc-shaped outer peripheral portion 92 of the fixture 91. .
[0022]
FIG. 10 shows a state in which the support tube 81 is at the 0 degree and 90 degree positions. The support tube 81 is provided with a projection 83 that is larger than the faucet insertion hole at the end of the semi-cylindrical shape, and the fixture 91 fitted to the support tube 81 has an arc center as shown in FIG. Protrusions 93 protruding to the side are provided. When the support tube 81 and the fixture 91 are combined by the above method, when the support tube 81 is rotated from the 0 degree position to the 90 degree direction, the projection end surface 83a of the support tube 81 and the projection 93 of the fixture 91 are formed. It can abut and stop rotating at 90 degrees.
[0023]
When the support tube 81 is inserted into the faucet insertion hole, the protrusion 83 of the support tube 81 is larger than the faucet insertion hole, so if it is inserted as it is in parallel with the faucet attachment shaft and the attachment shaft of the support tube 81, physical Therefore, the protrusion 83 is caught and cannot be inserted. Therefore, as shown in FIG. 12, the shape of the insertion portion of the support tube 81 is a semi-cylindrical shape. By inserting it at an angle with respect to the faucet mounting shaft, it is possible to insert even if there is a protrusion partly larger than the faucet insertion hole.
[0024]
Further, when the support pipe 81 is rotated in the 0 degree direction from the 90 degree position, the protrusion 83 of the support pipe 81 can come into contact with the protrusion 33 of the faucet panel 24 and stop rotating at the 0 degree position.
[0025]
Finally, the cover 101 shown in FIG. 10 is used when the water discharger 22 is pulled out and the hose 27 is slid, and the hose 27 comes into contact with the support tube 81 or the faucet panel 24 to generate friction. Good. As the material of the support tube 81 and the faucet panel 24, ABS resin is often used and the wear resistance is poor. Therefore, if the cover 101 made of a material with excellent wear resistance, such as polyacetal, is used for the friction part, the deterioration of the parts due to friction can be reduced, and further, as a guide role when the hose 27 cannot slide well due to the stepped parts etc. Can be expected. The cover 101 can be screwed to the boss 72 of the faucet panel together with the screw fixing hole 74 of the fixture 73.
