【０００１】
【発明の属する技術分野】
本発明は、浴槽本体内に着脱自在に架設される腰掛け用板を備えた浴槽に関するものである。
【０００２】
【従来の技術】
従来から、図７、８に示す如く、浴槽本体１の相対向する両側内壁面２に受け段部３を形成し、両側の受け段部３間に着脱自在に架設される腰掛け用板４を備えてなる浴槽は知られている。この浴槽は、実開平３−２２７８４号公報に開示されたものである。この浴槽においては、腰掛け用板４を取り付けたり取り外したりして、浴槽本体１内に一人或いは二人がいろいろなパターンで入浴することができて使い勝手は良好で便利である。
【０００３】
すなわち、図９に示す如く、一人で入浴する場合には、（ａ）のように、腰掛け用板４を取り外して、浴槽の底部に座り脚を伸ばして深く入浴したり、（ｂ）のように、腰掛け用板４を取り付けて、この腰掛け用板４上に座って浅く入浴したりすることができ、又、二人で入浴する場合には、（ｃ）のように、腰掛け用板４を取り付けて、一人はこの腰掛け用板４上に座って浅く入浴し、対向するもう一人は浴槽の底部に座り同腰掛け用板４の下に脚を伸ばして深く入浴したり、（ｄ）のように、腰掛け用板４を取り外して、対向する二人共が浴槽の底部に座って深く入浴したりすることができて便利である。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の技術にあっては、両側の受け段部３間に架設された腰掛け用板４が浮き上がったり、浴槽本体１内の湯水の流れによってずれ動いたりして、同腰掛け用板４の安定性が悪く、この腰掛け用板４上に座っている際にも同腰掛け用板４はずれ動き易くて安全性にも問題があった。又、腰掛け用板４を重くしてその設置安定性を高めようとすると、同腰掛け用板４を着脱させたり持ち運んだりするのに重くなって、取り扱い難く不便になるという問題を生じるものであった。
【０００５】
本発明は、上記従来の技術における問題を悉く解決するために発明されたもので、その課題は、腰掛け用板が安定して架設され、その浮き上がりやずれ動きが防止されて使用時の安全性は向上し、同腰掛け用板を軽くすることが可能となってその使い勝手も良好となる浴槽を提供することである。
【０００６】
【課題を解決するための手段】
本発明の請求項１記載の浴槽は、浴槽本体の相対向する両側内壁面に受け段部を形成し、両側の受け段部間に着脱自在に架設される腰掛け用板を備えてなる浴槽であって、受け段部の上側において浴槽本体の内壁面に着脱自在に取着され、腰掛け用板を上方から押えてその浮き上がりを阻止すると共に、同腰掛け用板の水平方向の移動を阻止する止め具を備え、腰掛け用板の後端縁が浴槽本体の内壁面に沿って当止されるものであり、止め具を、この腰掛け用板の側縁部の上面に沿った横片部と、同腰掛け用板の側縁部の前端縁に当止する縦片部と、を有するよう略Ｌ字状に形成し、止め具の裏面に浴槽本体の内壁面に着脱自在に取着される吸着盤を設け、同止め具を吸着盤と共に軟質材で一体に形成し、止め具の裏側端縁には凸リブが一体に突設されており、この凸リブよりも若干突出する程度に前記吸着盤は突設されていることを特徴とする。
【０００７】
したがって、この場合、浴槽本体の相対向する両側内壁面に形成された両側の受け段部間に着脱自在に架設される腰掛け用板を備えているので、この腰掛け用板を同両受け段部間に架設して取り付け、同腰掛け用板上に座って浅く入浴することができ、又、この腰掛け用板を取り外し、同浴槽本体の底部に座って深く入浴することもでき、いろいろな入浴パターンを楽しむことができる。
【０００８】
しかも、腰掛け用板を上方から押えてその浮き上がりを阻止すると共に、同腰掛け用板の水平方向の移動を阻止する止め具を備えているので、腰掛け用板を架設して使用する際に、この止め具を用いることにより、同腰掛け用板の浮き上がりやずれ動きを防止することができ、同腰掛け用板の使用時の設置安定性及びそれによる安全性は向上される。
【０００９】
更に、前記止め具が受け段部の上側において浴槽本体の内壁面に着脱自在に取着されるものであるため、腰掛け用板の不使用時には、この腰掛け用板と共に同止め具を取り外すことができ、その使い勝手は良好なものである。又、止め具を用いることで腰掛け用板の安定性が確保されるため、この腰掛け用板を重くする必要はなくなり、同腰掛け用板を着脱させたり持ち運んだりし易いものとすることができる。
【００１１】
更に、腰掛け用板の後端縁が浴槽本体の内壁面に沿って当止されるものであるため、この腰掛け用板を架設して使用している際に、その後側に隙間を生じることがなく座り心地は良好で、同腰掛け用板の後方へのずれ動きも確実に防止される。しかも、止め具が略Ｌ字状に形成されて、その横片部は腰掛け用板の側縁部の上面に沿い、その縦片部は同腰掛け用板の側縁部の前縁部に当止されるので、この腰掛け用板の浮き上がり及び前方へのずれ動きが確実に防止される。それ故、腰掛け用板の使用時の安定性がより向上される。
更に、止め具の裏面に浴槽本体の内壁面に着脱自在に取着される吸着盤が設けられているので、この吸着盤を同浴槽本体の内壁面に吸着させたり取り外したりして、同止め具を簡単に着脱できる。しかも、止め具が吸着盤と共に軟質材で一体に形成されているので、軟質ゴムや軟質合成樹脂等で同止め具全体を一体成形により容易に製作することができ、又、全体が軟質となることで、腕や身体に当たっても傷つくことはなく、安全性がより向上され、滑り難くなって腰掛け用板のずれ動きも確実に防止される。
更に、吸着盤が浴槽本体の内壁面に吸着された状態では、凸リブが同内壁面に当接されることになって、止め具は安定した状態で固定される。
【００１２】
本発明の請求項２記載の浴槽は、上記請求項１記載の浴槽において、横片部と縦片部との連設部位における外側コーナー部分、及び、同横片部の後端部分、同縦片部の下端部分、を各々Ｒ形状にしたことを特徴とする。
【００１３】
したがって、この場合は特に、横片部と縦片部との連設部位における外側コーナー部分、及び、同横片部の後端部分、同縦片部の下端部分、が各々Ｒ形状に形成されるので、これ等の部分はいずれも入浴時に腕や身体等が当たり易い部位であるものの、各々がＲ形状に形成されていて、肌当たりは滑らかとなり、安全性がより向上される。
【００１６】
【発明の実施の形態】
図１、２は、本発明の請求項全てに対応した一実施形態である浴槽を示している。この浴槽は、浴槽本体１の相対向する両側内壁面２に受け段部３を形成したものであり、両側の受け段部３間に着脱自在に架設される腰掛け用板４を備えている。そして、この浴槽では、受け段部３の上側において浴槽本体１の内壁面２に着脱自在に取着され、腰掛け用板４を上方から押えてその浮き上がりを阻止すると共に、同腰掛け用板４の水平方向の移動を阻止する止め具５を備えている。止め具５については、図３〜図６に詳細に示している。
【００１７】
この場合、腰掛け用板４の後端縁６が浴槽本体１の内壁面２に沿って当止されるものであり、止め具５を、この腰掛け用板４の側縁部７の上面に沿った横片部８と、同腰掛け用板４の側縁部７の前端縁９に当止する縦片部10と、を有するよう略Ｌ字状に形成している。ここでは、横片部８と縦片部10との連設部位における外側コーナー部分11、及び、同横片部８の後端部分12、同縦片部10の下端部分13、を各々Ｒ形状に形成してもいる。又、止め具５の裏面に浴槽本体１の内壁面２に着脱自在に取着される吸着盤14を設け、同止め具５を吸着盤14と共に軟質材で一体に形成してもいる。
【００１８】
以下、この実施形態の浴槽を詳細に説明する。浴槽本体１は合成樹脂、ステンレス等の金属板等で一体に形成されたものである。浴槽本体１の内部は平面視略ダルマ状の上方へ開口した凹所として形成されており、この凹所は上方程巾広く形成されていて、その上端開口縁には外方へ折曲突出したフランジ部が一体に形成されている。浴槽本体１の内壁面２は、止め具５の裏側に突設される吸着盤14が吸着し得る程度の平滑面に形成されている。
【００１９】
又、浴槽本体１の前記凹所はダルマ状ではあるものの、短手巾方向で対向する両側内壁面２が相互に略平行となるように形成されており、腰掛け用板４は上方からでも前方からでも同浴槽本体１内に差し入れるようにして取り付けることができる。この場合、浴槽本体１の短手巾方向で対向する両側内壁面２を相互に平行とならないよう極端な湾曲状に形成してやると、腰掛け用板４は前方へずれ動き難くなるが、上方からのみ嵌め込むようにして取り付けられるものとなる。
【００２０】
浴槽本体１の内壁面２には、その上下中程高さ位置に全周にわたる受け段部３が形成されている。受け段部３は全周に設けられなくても、最低限、腰掛け用板４が架設されるようにその両端が位置する部分にのみ設けられれば良い。又、ここで、受け段部３は階段状に形成されているが、浴槽本体１の内壁面２に水平方向の凹溝を設けて形成しても良く、この場合、凹溝の下側の溝内面が受け段部３となる。いずれにしても、受け段部３は、その上に腰掛け用板４の端部が載置される程度の略水平な面を有してれば良いものである。
【００２１】
腰掛け用板４は略半円形状で、その円弧状部分（後端縁６及び両側縁部７）が浴槽本体１の内壁面２に沿うよう形成されている。又、腰掛け用板４は軽量な材質、例えば、合成樹脂或いはその発泡体や中空形状体または木質板等でなり、浴槽本体１の前記凹所の開口を１／３〜１／４覆う程度の大きさの平板状に形成されている。そして、腰掛け用板４の円弧状の後端縁６及び両側縁部７は、浴槽本体１の内壁面２に沿った状態で前記受け段部３上に載置支持される。
【００２２】
この状態では、腰掛け用板４が浴槽本体１内に溜められた湯水の流れ動きによって浮き上がったり前方へずれ動いたりし易いものであり、これを防止するために、前記受け段部３の上側において同浴槽本体１の相対向する両側の内壁面２に各々止め具５を取着する。この場合、対の止め具５を両側の内壁面２に配置取着することで、腰掛け用板４をより安定した状態で保持することができ、なお、この対の止め具５は対称形状に形成されている。
【００２３】
止め具５は軟質ゴムや軟質合成樹脂等の摩擦抵抗が大きくて密着性に優れた軟質材により一体成形されたもので、図３〜４に示す如く、横片部８と縦片部10とで略Ｌ字状に形成されている。ここでは、横片部８と縦片部10との連設部位における外側コーナー部分11、及び、同横片部８の後端部分12、同縦片部10の下端部分13、が各々丸みをもったＲ形状に形成されている。
【００２４】
そして、止め具５の横片部８の裏面には三つの吸着盤14が、縦片部10の裏面には一つの吸着盤14が一体に突設されている。又、止め具５の裏側全周端縁には凸リブ15が一体に突設されており、この凸リブ15よりも若干突出する程度に前記吸着盤14は突設されている。それ故、吸着盤14が浴槽本体１の内壁面２に吸着された状態では、凸リブ15が同内壁面２に当接されることになって、止め具５は安定した状態で固定される。
【００２５】
又、止め具５の表側中程には、横片部８及び縦片部10の全長にわたる凹溝部16が形成されており、この凹溝部16と前記凸リブ15とで同止め具５は垂直面内にて湾曲変形し難い形状となっている。しかも、横片部８及び縦片部10の両方に吸着盤14が配設されているので、止め具５によって腰掛け用板４の両側縁部７の前端縁９付近は確実に保持される。すなわち、縦片部10が腰掛け用板４の側縁部７の前端縁９に当止され、横片部８が同前端縁９付近で腰掛け用板４の上面に沿って当接され、両側の止め具５によって同腰掛け用板４は確実に保持される。
【００２６】
又、止め具５は全体が軟質材で形成されることで、浴槽本体１の内壁面２に沿い変形して取着され易く取り扱い易いものとなっており、同内壁面２に取着された状態では、前記の如く、腰掛け用板４を確実に保持することができるものである。又、止め具５の各吸着盤14に対応する表側には凹部17が形成されており、この凹部17によって同吸着盤14は変形し易いものであり、浴槽本体１の内壁面２に対して着脱させ易く、しかも、確実に吸着し易いものである。
【００２７】
したがって、この実施形態の浴槽においては、浴槽本体１の相対向する両側内壁面２に形成された両側の受け段部３間に着脱自在に架設される腰掛け用板４を備えているので、この腰掛け用板４を同両受け段部３間に架設して取り付け、同腰掛け用板４上に座って浅く入浴することができ、又、この腰掛け用板４を取り外し、同浴槽本体１の底部に座って深く入浴することもでき、いろいろな入浴パターンを楽しむことができる。具体的には、上記従来の技術における図９で説明した内容と同様になるので、ここではその説明を省略する。
【００２８】
しかも、腰掛け用板４を上方から押えてその浮き上がりを阻止すると共に、同腰掛け用板４の水平方向の移動を阻止する止め具５を備えているので、腰掛け用板４を架設して使用する際に、この止め具５を用いることにより、同腰掛け用板４の浮き上がりやずれ動きを防止することができ、同腰掛け用板４の使用時の設置安定性及びそれによる安全性は向上される。
【００２９】
更に、前記止め具５が受け段部３の上側において浴槽本体１の内壁面２に着脱自在に取着されるものであるため、腰掛け用板４の不使用時には、この腰掛け用板４と共に同止め具５を取り外して片付けることができ、その使い勝手は良好なものである。又、止め具５を用いることで腰掛け用板４の安定性が確保されるため、この腰掛け用板４を重くする必要はなく、軽量材で形成することで、同腰掛け用板４を着脱させたり持ち運んだりし易いものとすることができる。
【００３０】
又、この実施形態の浴槽においては、腰掛け用板４の後端縁６が浴槽本体１の内壁面２に沿って当止されるものであるため、この腰掛け用板４を架設して使用している際に、その後側に隙間を生じることがなく座り心地は良好で、同腰掛け用板４の後方へのずれ動きも確実に防止される。しかも、止め具５が略Ｌ字状に形成されて、その横片部８は腰掛け用板４の側縁部７の上面に沿い、その縦片部10は同腰掛け用板４の側縁部７の前端縁９に当止され、このような止め具５が両側に配設されるので、この腰掛け用板４の浮き上がり及び前方へのずれ動きは確実に防止される。それ故に、腰掛け用板４の使用時の安定性がより向上されることとなる。
【００３１】
又、この実施形態の浴槽においては、横片部８と縦片部10との連設部位における外側コーナー部分11、及び、同横片部８の後端部分12、同縦片部10の下端部分13、が各々Ｒ形状に形成されるので、これ等の部分はいずれも入浴時に腕や身体等が当たり易い部位であるものの、各々がＲ形状に形成されていて、肌当たりは滑らかとなり、安全性がより向上される。
【００３２】
又、この実施形態の浴槽においては、止め具５の裏面に浴槽本体１の内壁面２に着脱自在に取着される吸着盤14が設けられているので、この吸着盤14を同浴槽本体１の内壁面２に吸着させたり取り外したりして、同止め具５を簡単に着脱させることができる。しかも、止め具５が吸着盤14と共に軟質材で一体に形成されているので、軟質ゴムや軟質合成樹脂等で同止め具全体を一体成形により容易に製作することができ、又、全体が軟質となることで取り扱い易く、腕や身体に当たっても傷つくことはなく、安全性がより向上され、腰掛け用板４との間で滑り難くなってこの腰掛け用板４のずれ動きも確実に防止される。
【００３３】
又、この実施形態の浴槽において、図１、２に示す如く、浴槽本体１の内壁面２にジェット噴流が噴出される吹出口18が設けられている場合には、特に、同ジェット噴流の勢いによって、腰掛け用板４が浮き上がったりずれ動いたりし易いところ、両側の止め具５でこれを確実に防止することができて、極めて有効なものとなる。
【００３４】
【発明の効果】
上述の如く、本発明の請求項１記載の浴槽においては、腰掛け用板を取り付けたり取り外したりして、種々の入浴パターンを楽しむことができ、しかも、同腰掛け用板の使用時に、その浮き上がりやずれ動きを止め具によって防止することができて、その設置安定性及び安全性は向上され、又、同腰掛け用板の不使用時には、この腰掛け用板と共に同止め具を取り外すことができて、その使い勝手は良好であり、同腰掛け用板を軽くして、その取り扱いも容易なものにすることができる。
更に、腰掛け用板の後端縁が浴槽本体の内壁面に沿って当止されるものであるため、この腰掛け用板を架設して使用している際に、その後側に隙間を生じることがなく座り心地は良好で、同腰掛け用板の後方へのずれ動きも確実に防止される。しかも、止め具が略Ｌ字状に形成されて、その横片部は腰掛け用板の側縁部の上面に沿い、その縦片部は同腰掛け用板の側縁部の前縁部に当止されるので、この腰掛け用板の浮き上がり及び前方へのずれ動きが確実に防止される。それ故、腰掛け用板の使用時の安定性がより向上される。
