Abstract

<P>PROBLEM TO BE SOLVED: To hold a double ring 8 on the fitting 5 side so that an end part 8b of the double ring does not turn to the outside. <P>SOLUTION: The double ring is formed double in the annular shape to connect a rubber plug part and a ball-chain part. In the double ring, the distance between end parts is set nearly equal to the outline dimensions of the fitting mounted on the rubber plug, and the outline dimensions of a double part of the double ring is set larger than the diameter of a through-hole formed in the fitting. Since the end part 8b of the double ring 8 is held on the fitting 5 side in this way so that the end part 8b does not turn to the outside, the end part 8b of the double ring 8 does not move to a position where the end part can be touched by fingers. Accordingly, a user will not injure a finger when the finger touches the end part 8b of the double ring 8 in cleaning, etc. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明は、浴槽、洗面化粧ボール等、排水口を備える場所に用いる排水栓で、特にゴム栓部とダブルリングに関する。
【0002】
【従来の技術】
浴槽や洗面化粧ボールの排水口に用いる排水栓1は、図5に示すように排水口に着脱されるゴム栓部2とゴム栓部2を支持する玉鎖部3と玉鎖部3を保持する保持部(図示しない)で構成され、ゴム栓部2と玉鎖部3は環状で二重に形成されたダブルリング8を介して連結されている。ゴム栓部2は、ゴム製の排水栓本体4と連結用の取付金具5で構成され、ゴム製の排水栓本体4の中央部に設けた中央孔(図示しない)に取付金具5を嵌通して組立てている。取付金具5の上部には、連結するための貫通孔5aを設けている。
玉鎖部3は、玉鎖6と玉鎖6の両端部の玉6aを挟持するとともに連結するためのカップリング7とで構成され、カップリング7は、連結するための孔7aと、玉6aを挟持するためのスリット7bとを備えている。
ダブルリング8を用いたゴム栓部2と玉鎖部3の連結方法は、ダブルリング8の二重部8aを治具など(図示しない)で拡開し、ダブルリング8の端部8bを取付金具5の貫通孔5aに挿入し、ダブルリング8を回転させながら押込んで取付ける。その後、カップリング7の孔7aに前述と同様の方法でダブルリング8を取付けている。
(例えば、特許文献1参照)
【0003】
特許文献1:実開平7−17870(3頁、第11図,4頁、第10図)
【0004】
【発明が解決しようとする課題】
しかしながら、従来技術では、取付金具5に設けた貫通孔5aの内径は、ダブルリング8の組付けが可能な範囲において任意の寸法に設定されているが、通常は、ダブルリング8の組付けを容易にするため、ダブルリング8の二重部8aの外形寸法よりも貫通孔5aの内径寸法は大きく設定されている。そのため、ダブルリング8が自由に回転でき、端部8bも任意の位置に移動することになる。例えば、図6のような位置にダブルリング8の端部8bが移動した状態で、掃除などをしているとダブルリング8の端部8bに指が触れてケガをする可能性がある。
【0005】
そこで、本発明では上記の問題点を解決するため、ダブルリング8の端部8bが外側に向かないように取付金具5側に保持することを目的とする。
【0006】
【課題を解決するための手段】
ゴム製の排水栓本体と連結用の取付金具を備えたゴム栓部と、玉鎖を挟持するとともに連結用のカップリングを備えた玉鎖部とを環状で二重に形成されたダブルリングを介して連結する排水栓において、前記ダブルリングの二重部外形寸法を前記取付金具に設けた貫通孔の内径寸法よりも大きく形成するとともに、前記ダブルリングの端部間の距離を前記取付金具の外形寸法と略同一に形成したことを特徴とする。
【0007】
これによりダブルリングの端部は、取付金具にほぼ当接した状態で組付けられるとともに、ダブルリングが回転するようなことはなくなる。そのため、ダブルリングの端部が、露出するようなこともなく、手や指などを切傷するケガを防ぐことができる。
【0008】
【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、本発明に係る排水栓を示す外観図である。図2は本発明の排水栓に用いるダブルリングを示す外観図である。図3は本発明の排水栓に用いるゴム栓部を示す外観図である。図4は本発明の排水栓に係るダブルリングと取付金具の取付方法を示す外観図である。図5は従来技術の排水栓を示す外観図である。図6は従来技術の排水栓に係るダブルリングの移動状態を示す外観図である。
【0009】
本発明の排水栓11も浴槽や洗面化粧ボールに取付ける方法は、従来技術と同様で、図1に示すように主に排水口に着脱される栓部2と栓部2を支持する玉鎖部3と玉鎖部3を保持する保持部(図示しない)で構成され、ゴム栓部2と玉鎖部3は、環状で二重に形成されたダブリング18を介して連結されている。
ゴム栓部2は、ゴム製の排水栓本体4に取付金具15が組付けられており、取付金具15の上部には貫通孔15aを設けている。玉鎖部3は、玉鎖6と玉鎖6の両端部に設けたカップリング7で構成され、カップリング7は、連結するための孔7aと、玉6aを挟持するためのスリット7bを備えている。
【0010】
図2、図3に示すように本発明の排水栓11に用いるダブルリング18は、ステンレス製のワイヤーを用いて二重の環状に形成し、ダブルリング18の端部18b間の距離Lが取付金具15の外形寸法D1とほぼ同一寸法(L≒D1)となる位置で切断して製作される。
また、ダブルリング18の二重に形成された二重部18aの外形寸法Wは、取付金具15に設けた貫通孔15aの内径D2よりも大きい寸法設定(W>D2)となっている。
図4に示すようにダブルリング18と取付金具15の組付け方法は、ダブルリング18の端部18b付近を治具(図示しない)などを用いて拡開し、取付金具15の貫通孔15aにダブルリング18の端部18bを挿入する。(図4(a))その後、ダブルリング18を回転させながら押込んでいくと、(図4(b))先に挿入したダブルリング18の端部18bが取付金具15に当接して取付け作業は終了する。(図4(c))
【0011】
ダブルリング18は許容差程度のガタツキしかなく、ダブルリング18はほぼ固定された状態で取付けられているので、取付金具15の貫通孔15aを通じて回転することはない。そのため、ダブルリング18の端部18bが露出することもなく、端部18bが使用者の手や指に触れる可能性は従来に比べて低くなり、掃除などの時に発生するケガを防止することができる。
尚、本発明は、前述のようにゴム栓部2と玉鎖部3とをダブルリング18を用いた連結に限定することなく、玉鎖部3を保持する保持部(図示しない)と玉鎖部3を連結するときに適用してもよい。
【0012】
【発明の効果】
排水栓本体に連結のための取付金具を設けた栓部と、玉鎖と該玉鎖を挟持し前記栓部と連結するための連結具とを備えた玉鎖部と、を二重に形成されたダブルリングを介して連結させた排水栓において、前記ダブルリングの切断端部間の距離を前記取付金具の外形寸法と略同一に設定するとともに、ダブルリングの二重部外形寸法を取付金具に設けた貫通穴の直径寸法よりも大きく設定したので、ダブルリングの切断端面が取付金具部側に固定されるので切断端面部に手が触れる可能性は低くなり掃除などの時に発生するケガを防止することができる。
