Description

【０００１】
【発明の属する技術分野】
本発明は、表面にメッキを施したシャワーヘッドに関する。
【０００２】
【従来の技術】
流し台，洗面台又は浴室等で使用される混合水栓において、湯水を外部へ吐水するため装着されているシャワーヘッドは、一般にコストダウン，軽量化，熱伝達防止等の理由により合成樹脂製であるが、美観，高級感を向上させるため表面に金属色のメッキを施すことが行われている。合成樹脂製のシャワーヘッドにメッキ処理を施す場合、湯水が通過する通水路の内壁面までメッキが付着してしまうと、通水路を通過するのが水であればそれほど問題にならないが、高温の熱湯であるとこの熱湯の影響で合成樹脂材は熱膨張が発生し、メッキは内壁面から剥離してしまい、通水路の目詰まりにより湯水の吐水状態が不均一になるうえ、湯水が飲料水であると、メッキが体内に入り人体に悪影響を及ぼす恐れがある。そこで従来はシャワーヘッドの内部を二重構造として湯水がメッキに触れないようにしていた。
【０００３】
図４によりこのようなシャワーヘッドを説明すると、シャワーヘッド３１は全体が合成樹脂により一体に形成された中空筒状で、表面にメッキが施され、把手部３２の内周の空間部３３に装着した円筒状の通水ガイド３４に流路３５を形成し、空間部３３の先端には縦方向の吐水室３６を形成している。該吐水室３６は下部に開口部３７が形成され、該開口部３７から吐水室３６の内壁面を覆うことのできる被覆部材３８を装着し、該被覆部材３８は前記通水ガイド３４とバイパス管３９により接続し、被覆部材３８の下部には湯水を外部へ吐水するための吐水部材４０が装着される。
【０００４】
蛇腹状のホース４１の先端に結合した接続部材４２は、外周面に雄ねじ部４２ａを形成し、該雄ねじ部４２ａは前記通水ガイド３４の内周面に形成した雌ねじ部３４ａに螺着することで、ホース４１はシャワーヘッド３１に接続されるものである。
【０００５】
上記のものにあっては、シャワーヘッドの内部には、ホースから供給される湯水がメッキに触れないように通水ガイド，被覆部材及びバイパス管を装着する必要があり、多数の部品を必要とするため、シャワーヘッドの組立て作業が面倒であり、しかも多数の部品を収容するため、全体をコンパクトにすることができず、デザインの制約となるものであった。
【０００６】
【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、表面にメッキを施したシャワーヘッドにおいて、メッキが施された内壁面を少ない部品点数で覆うことで組立性を向上させ、しかも全体をコンパクトにして使用感及び美観を向上させることである。
【０００７】
【課題を解決するための手段】
本発明は請求項１では、ホースの先端に結合した接続部材が差し込まれる接続孔を穿設した把手部と、該把手部の先端で湯水を外部へ吐水する吐水部材が下部に開口した開口部から装着される吐水室とを備え、表面にメッキを施したシャワーヘッドにおいて、前記吐水室には内壁面を覆う被覆部材を装着し、該被覆部材は前記接続部材が差し込まれる横孔を穿設し、前記接続部材は外周面に抜け止め用のリングが係合する係止溝を形成し、接続部材を把手部の接続孔から被覆部材の流路へ臨むように横孔に差し込み、リングを開口部から被覆部材の流路へ挿入して接続部材の係止溝へ係合することでホースを接続するものである。
【０００８】
請求項２では、前記リングは接続部材の係止溝から取り外し自在としたものである。
【０００９】
【発明の実施の形態】
以下、本発明の実施の形態を図に基づいて詳細に説明する。
この発明のシャワーヘッド１は図１に示すように全体が合成樹脂により一体に形成された中空屈曲形状で、表面全体にニッケルクローム等、耐食性に優れ、美観，高級感を与えることのできる金属色のメッキ２が施され、後述するホース１８を接続するため基端に形成した円筒状の把手部３の先端に、縦方向の吐水室５を備えている。該吐水室５の下部には開口部６が形成され、該開口部６から吐水室５には、該吐水室５の内部壁面を覆うことのできる被覆部材８が装着され、該被覆部材８の下部には、湯水を外部へ吐水するための流路が形成されている吐水部材１０が装着される。
【００１０】
前記把手部３は、内部に形成した接続孔４に円筒状の円筒部材９を収容し、該円筒部材９は内周面にセレーション９ａが刻設され、この円筒部材９と前記吐水室５の間に環状の壁７が形成され、該壁７には前記被覆部材８に穿設した横孔８ａと円筒部材９に穿設した横孔９ｂを連通させるための挿通孔７ａを穿設している。
【００１１】
前記接続部材１１は内部に湯水の通路１２が形成された略円筒形で、ホース１８の先端に結合する大径部１３と、該大径部１３の先端に突出し、大径部１３よりやや小径に形成した小径部１４と、大径部１３と小径部１４の間で大径部１３よりさらに大径に形成した環状の鍔部１５とからなり、該鍔部１５は前記円筒部材９に穿設した横孔９ｂより大径に形成されているため、該横孔９ｂを挿通できないが、小径部１４は横孔９ｂ及び壁７に穿設した挿通孔７ａより小径に形成されているため、図２に示すように該挿通孔７ａを挿通して被覆部材８の横孔８ａを挿通し、被覆部材８の流路８ｂに臨ませることができる。
【００１２】
前記小径部１４の略先端の外周面には、先端から係止溝１４ａと環状溝１４ｂとが併設して環状に形成されており、該環状溝１４ｂには漏水防止用のシール材１４ｃが装着され、被覆部材８の流路８ｂに臨ませた係止溝１４ａに対し、シャワーヘッド１の開口部６から後述するリング１７を係合させることができる。
【００１３】
前記リング１７は、弾力性を有する材質で略Ｕ字形に屈曲して形成され、図２に示すように外径を被覆部材８の横孔８ａより大径とすることで、接続部材１１の係止溝１４ａにこのリング１７を係合させれば、接続部材１１はシャワーヘッド１に接続され、ホース１８はシャワーヘッド１から抜けることがないようにしている。
【００１４】
前記ホース１８は内側の合成樹脂製ホース１８ａと、該合成樹脂製ホース１８ａを覆い外周面に螺旋状の凹凸溝１８ｃを一定の間隔で多数形成した金属製ホース１８ｂとの間に狭持された固定筒１９の外周面に溝１９ａを形成し、切欠部が形成されている抜け止めリング２０を前記溝１９ａに固定筒１９の外周面より突出するように弾力的に装着している。前記接続部材１１は大径部１３の内周に前記抜け止めリング２０が弾力的に装着される溝１６を形成しているので、ホース１８の先端を接続部材１１の通路１２に挿入すると、抜け止めリング２０は溝１６に弾力的に装着され、接続部材１１はホース１８に対し回転自在で、かつ容易に外れないようにしている。
【００１５】
先端に接続部材１１を結合したホース１８をシャワーヘッド１に接続するには、シャワーヘッド１の吐水室５に被覆部材８を装着した後に、図２に示すようにまず接続部材１１をシャワーヘッド１の接続孔４に挿入する。すると接続部材１１の鍔部１５が円筒部材９に当接し、小径部１４は円筒部材９の横孔９ｂ，壁７の挿通孔７ａ及び被覆部材８の横孔８ａを挿通して、被覆部材８の流路８ｂへ臨む。
【００１６】
次にシャワーヘッド１の開口部６から被覆部材８の流路８ｂへ向けてリング１７を挿入し、接続部材１１の係止溝１４ａに弾力的に係合すれば、接続部材１１はシャワーヘッド１へ接続される。
【００１７】
そして図３に示すように、シャワーヘッド１の開口部６から吐水室５に吐水部材１０を装着すれば、シャワーヘッド１とホース１８の接続は終了する。
【００１８】
なお、シャワーヘッド１からホース１８を外すには、シャワーヘッド１の開口部６から装着した吐水部材１０を取り外し、被覆部材８の流路８ｂに指を入れて接続部材１１からリング１７を引き抜けば、ホース１８をシャワーヘッド１から引き抜くだけで容易に分解することができる。従って、ホースが損傷したり、シャワーヘッドのみを交換する場合に、容易に分解して交換することができる。
【００１９】
【発明の効果】
本発明では請求項１では、ホースの先端に結合した接続部材が差し込まれる接続孔を穿設した把手部と、該把手部の先端で湯水を外部へ吐水する吐水部材が下部に開口した開口部から装着される吐水室とを備え、表面にメッキを施したシャワーヘッドにおいて、前記吐水室には内壁面を覆う被覆部材を装着し、該被覆部材は前記接続部材が差し込まれる横孔を穿設し、前記接続部材は外周面に抜け止め用のリングが係合する係止溝を形成し、接続部材を把手部の接続孔から被覆部材の流路へ臨むように横孔に差し込み、リングを開口部から被覆部材の流路へ挿入して接続部材の係止溝へ係合することでホースを接続する。従ってシャワーヘッドとホースの接続を、吐水室に装着した被覆部材の流路でリングを接続部材の係止溝に係合させる作業で行うので、メッキが湯水に混入しないようにするため、シャワーヘッドの内壁に装着するのは吐水室の内壁面を覆う被覆部材だけでよく、従来のようにシャワーヘッドの内部で湯水がメッキに触れないようにするため多数の物品を装着する必要がなく、シャワーヘッドの組立時の作業性が大幅に向上するうえ、コストダウンを図ることができる。また、シャワーヘッドは従来のように把手部の内部にホースを接続するためのねじを形成する必要がなく、ホース先端の接続部材は被覆部材の流路でリングにより接続するので、コンパクトに形成して、手に持って容易に使用することができ、しかもデザインの自由度が増し、使用感及び美観を向上させることができる。
【００２０】
また、請求項２では前記リングは接続部材の係止溝から取り外し自在としたので、接続作業だけでなく分解作業も容易に行うことができ、ホースやシャワーヘッドの交換を容易に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a shower head having a surface plated.
[0002]
[Prior art]
In mixed faucets used in sinks, washstands, bathrooms, etc., shower heads installed to discharge hot water to the outside are generally made of synthetic resin for reasons such as cost reduction, weight reduction, and heat transfer prevention. However, metal color plating is applied to the surface to improve aesthetics and luxury. When plating the shower head made of synthetic resin, if the plating adheres to the inner wall surface of the water passage through which hot water passes, it is not a problem if the water passes through the water passage. If hot water is used, the synthetic resin material will expand due to the influence of the hot water, the plating will peel off from the inner wall surface, the clogging of the water passage will cause the water discharge to be uneven, and the hot water will be drinking water. If so, the plating may enter the body and adversely affect the human body. Therefore, conventionally, the shower head has a double structure so that hot water does not touch the plating.
[0003]
Such a shower head will be described with reference to FIG. 4. The shower head 31 is a hollow cylinder formed integrally of synthetic resin, plated on the surface, and mounted in the inner space portion 33 of the handle portion 32. A flow path 35 is formed in the cylindrical water flow guide 34, and a vertical water discharge chamber 36 is formed at the tip of the space 33. The water discharge chamber 36 is formed with an opening 37 in the lower portion, and a covering member 38 capable of covering the inner wall surface of the water discharge chamber 36 from the opening 37 is attached. The covering member 38 is connected to the water flow guide 34 and the bypass pipe. 39, and a water discharge member 40 for discharging hot water to the outside is attached to the lower part of the covering member 38.
[0004]

The hose 41 is connected to the shower head 31.
[0005]
In the above, it is necessary to install a water flow guide, a covering member and a bypass pipe in the shower head so that hot water supplied from the hose does not touch the plating, and many parts are required. Therefore, the assembling work of the shower head is troublesome, and since a large number of parts are accommodated, the whole cannot be made compact, which is a design restriction.
[0006]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to improve the assemblability of the shower head having a plated surface by covering the plated inner wall surface with a small number of parts, and to make the whole compact and feel good to use. It is to improve aesthetics.
[0007]
