Description

【０００１】
【発明の属する技術分野】
本発明は、複数の蓋体を相互に軸支して折れ蓋構成とし、洗濯機本体の上面に開閉自在に設ける洗濯機の蓋に関するものである。
【０００２】
【従来の技術】
従来の洗濯機の蓋は、図１１および図１２に示すように構成していた。以下、その構成について説明する。
【０００３】
図１１に示すように、開閉蓋１は、一端を軸支部２により上方へ回動自在に軸支して洗濯機本体３の上面に設けている。この開閉蓋１は軸支部２に略平行な軸線４に沿って折り畳み可能な２枚の蓋体１ａ、１ｂで構成している。一方の蓋体１ａの端部には、図１２（ａ）に示すように、軸線４に沿って片持支持される複数個の支持軸５をほぼ両端６ａ、６ｂから略等間隔に一体に形成し、他方の蓋体４ｂには、図１２（ｂ）に示すように、支持軸５を保持する同数の軸受部７を支持軸５と対応する位置に一体に形成している。
【０００４】
これら２枚の蓋体１ａ、１ｂは、支持軸５を軸受部７に貫通させ、回動自在に連結している。
【０００５】
【発明が解決しようとする課題】
最近の一般家庭では、全自動洗濯機の普及が著しい。利便性は向上したが、洗濯中の水流や衣類の動きを確認したいという使用者の要望も多い。
【０００６】
開閉蓋１を構成する蓋体１ａ、１ｂを透視性材料で構成した場合、洗濯機本体３の表面から開閉蓋１の裏面の支持軸５、軸受部７などの構造が透視でき、デザイン性を非常に損なうものであった。
【０００７】
また、蓋体１ａ、１ｂの材料は、安価で、対候性、対薬品性が優れているポリプロピレン等のオレフィン系樹脂を使用する場合が多いが、この材料は成形時の反り、ひずみを生じて、形状が安定しない問題がある。たとえば、成形時の蓋体１ａ、１ｂの反りが大きい場合、両端部の軸受部７のずれが大きく、蓋体１ａ、１ｂを連結するとき、支持軸５を軸受部７に貫通させる作業では、このずれを合わせながら行う必要があり、非常に力が必要で手間がかかっていた。
【０００８】
本発明は上記従来の課題を解決するもので、複数の蓋体を確実に連結するとともに、デザイン性の向上を目的としている。
【０００９】
【課題を解決するための手段】
前記目的を達成するために本発明は、洗濯機本体の上面に設けた開閉蓋を透視材からなる前後の蓋体で構成するととともに、前方蓋体の後端中央部分と後方蓋体の前端中央部分には相係合する支持軸と軸受部とを形成して折り畳み可能とし、さらに前記支持軸、軸受部と対応する前方蓋体の後方中央部位には把手部を設けた洗濯機の蓋であって、前記前後の蓋体の一方に凹部を設けるとともに、他方の蓋体に凸部を設け、前記前後の蓋体を広げた状態で前記凹部と凸部とを嵌め合い、前記前後の蓋体の表面が面一状態になる構成とし、前記凹部と凸部は、前記前後の蓋体の合わせ部分の両端近くに設け、前記一方の蓋体の凹部と他方の蓋体の凸部の嵌め合いのすり合わせ面は、前記蓋体相互間の回転中心とほぼ同じ点を中心とした略円弧状の面としたものである。
【００１０】
したがって、蓋体を透視性材料で構成した場合でも、表面から軸支構造が見えにくくすることができ、加えて、蓋体が多少反っている場合でも、複数の蓋体を容易に連結して折り畳み蓋を構成することができ、また、蓋体上方から強い応力がかかった場合や、蓋を開く方向に強い応力がかかった場合に、軸支部分にかかる力を軽減化し、応力による軸部や軸受部の破損を防止することができ、強い機械的強度を得ることができ、そして、スムーズな蓋体の開閉が可能となるものである。
【００１１】
【発明の実施の形態】
本発明の洗濯機の蓋は、洗濯機本体の上面に設けた開閉蓋を透視材からなる前後の蓋体で構成するととともに、前方蓋体の後端中央部分と後方蓋体の前端中央部分には相係合する支持軸と軸受部とを形成して折り畳み可能とし、さらに前記支持軸、軸受部と対応する前方蓋体の後方中央部位には把手部を設けた洗濯機の蓋であって、前記前後の蓋体の一方に凹部を設けるとともに、他方の蓋体に凸部を設け、前記前後の蓋体を広げた状態で前記凹部と凸部とを嵌め合い、前記前後の蓋体の表面が面一状態になる構成とし、前記凹部と凸部は、前記前後の蓋体の合わせ部分の両端近くに設け、前記一方の蓋体の凹部と他方の蓋体の凸部の嵌め合いのすり合わせ面は、前記蓋体相互間の回転中心とほぼ同じ点を中心とした略円弧状の面としたものである。
【００１２】
したがって、蓋体を透視性材料で構成した場合でも、表面から軸支構造が見えにくくすることができ、加えて、蓋体が多少反っている場合でも、複数の蓋体を容易に連結して折り畳み蓋を構成することができ、また、蓋体上方から強い応力がかかった場合や、蓋を開く方向に強い応力がかかった場合に、軸支部分にかかる力を軽減化し、応力による軸部や軸受部の破損を防止することができ、強い機械的強度を得ることができ、そして、スムーズな蓋体の開閉が可能となる。
【００１３】
また、すり合わせ面は、前後蓋体相互間の回転中心とほぼ同じ点を中心とした略円弧状の面と、開口部を広げるような面からなるようにしているので、蓋体を広げるときに成形時の蓋体の反りを徐々に矯正しながら嵌め合わされ、さらにスムーズな開閉が可能となる。
【００１４】
【実施例】
以下、本発明の実施例について、図面を参照しながら説明する。
【００１５】
（実施例１）
図１に示すように、開閉蓋８は、一端を軸支部９により上方へ回動自在に軸支して洗濯機本体（図示せず）の上面に設けている。この開閉蓋８は軸支部９に略平行な軸線１０に沿って折り畳み可能な２枚の蓋体８ａ、８ｂで構成している。一方の蓋体８ａの端部には、図２（ａ）に示すように、軸線１０に沿って片持支持される複数個の支持軸１１を略中央部に略等間隔に一体に形成し、他方の蓋体８ｂには、図２（ｂ）に示すように、支持軸１１を保持する同数の軸受部１２を支持軸１１と対応する位置に一体に形成し、軸支部１３を構成している。
【００１６】
蓋体８ａ、８ｂは、透視性の材料で構成し、洗濯機本体の前方側の蓋体８ｂに把手部１４を設け、この把手部１４と対応する位置に蓋体８ａ、８ｂを相互に軸支する軸支部１３を設けている。
【００１７】
上記構成において、２枚の蓋体８ａ、８ｂを相互に略中央部にて支持軸１１を軸受部１２に貫通させて、軸支部１３により軸支し、折れ蓋構成としているので、蓋体８ａ、８ｂが多少反った場合でも、蓋体８ａ、８ｂの略中央部の反り量は、両端部の反り量と比較して少ないために、反りの影響が少なく、蓋体８ａ、８ｂを容易に連結できて折れ蓋を構成することができる。
【００１８】
また、洗濯機本体の前方側の蓋体８ｂの略中央部に把手部１４を設け、この把手部１４と対応する位置に蓋体８ａ、８ｂを相互に軸支する軸支部１３を設けているので、蓋体８ａ、８ｂを透視性の材料で構成した場合でも、表面から蓋裏面の軸支構造が見えにくくすることができ、デザイン性を損なわないようにできる。
【００１９】
（実施例２）
図３に示すように、蓋体８ｃは、端部に軸線に沿って片持支持される複数個の支持軸１１ａを略中央部に略等間隔に一体に形成し、蓋体８ｄは、支持軸１１ａを保持する同数の軸受部１２ａを支持軸１１ａと対応する位置に一体に形成して軸支部を構成し、これら蓋体８ｃと蓋体８ｄとを軸支部にて連結して開閉蓋を構成する。
【００２０】
蓋体８ｄに係止用リブ１５を設けるとともに、蓋体８ｃに凹部１６を設け、図４に示すように、２枚の蓋体８ｃ、８ｄを同一平面状に広げたとき、係止用リブ１５が凹部１６内に上方から入り込む構成としている。
【００２１】
上記構成において、図５に示すように、使用者が蓋の上に重量物を載せるなど、蓋体８ｃ、８ｄの上方から強い力Ｆがかかった場合や、蓋体８ｄを開く方向に強い力Ｇがかかった場合には、係止用リブ１５が蓋体８ｃ、８ｄの合わせ面の表面側の点Ａを中心として裏面側を広げる方向に力Ｈがかかる。この力Ｈを蓋体８ｃの凹部１６で受けることができ、軸支部分にかかる力を軽減することができ、従来から発生していた応力による支持軸１１ａや、軸受部１２ａの破損を防止することができ、強い機械的強度を得ることができる。
【００２２】
（実施例３）
図６に示すように、２枚の蓋体８ｅ、８ｆは、相互に軸支して折れ蓋構成として開閉蓋を構成しており、蓋体８ｅ、８ｆの合わせ部分１７において、蓋体８ｆに凹部１８を設けるとともに蓋体８ｅに凸部１９を設け、蓋体８ｅ、８ｆを連結して広げた状態で、この凹部１８と凸部１９の嵌め合いによって、蓋体８ｅ、８ｆ表面が面一状態になるよう構成している。
【００２３】
この凹部１８と凸部１９は、蓋体８ｅ、８ｆの合わせ部分１７の両端近く（図２参照）に設けることにより、小さい形状でも大きな効果が得られる。
【００２４】
また、図７に示すように、凹部１８と凸部１９の嵌め合いのすり合わせ面２０ａ、２０ｂを蓋体８ｅ、８ｆ相互の回転中心Ｐとほぼ同じ点を中心とした半径Ｒの略円弧状に構成している。また、凹部１８を略円弧状の面２０ｂと開口部を広げるような面２１で構成している。
【００２５】
さらに、図８に示すように、凹部１８を洗濯機本体２２の前方側の蓋体８ｆに設け、凸部１９は図示していないが、洗濯機本体２２の後方側の蓋体８ｅに設けている。飾り板２３、２４はそれぞれ蓋体８ｅ、８ｆを覆うものである。
【００２６】
上記構成において、蓋体８ｅ、８ｆを連結して広げた状態で、凹部１８と凸部１９の嵌め合い、蓋体８ｅ、８ｆの表面が面一状態になる構成とすることにより、蓋体８ｅ、８ｆが多少反った場合でも、蓋体８ｅ、８ｆを連結して構成した開閉蓋を閉じたとき、蓋体８ｅ、８ｆの表面が同一平面状になり、開閉をスム−ズにすることができる。
【００２７】
また、蓋体８ｅ、８ｆの合わせ部分１７の両端近くで、蓋体８ｆに凹部１８を設け、蓋体８ｅに凸部１９を設けることにより、凹部１８、凸部１９が小さな形状でも蓋体８ｅ、８ｆの表面を面一状態にすることができる。
【００２８】
また、蓋体８ｆの凹部１８と、蓋体８ｅの凸部１９の嵌め合いのすり合わせ面を、蓋体８ｅ、８ｆ相互間の回転中心Ｐとほぼ同じ点を中心とした半径Ｒの略円弧状の面とすることにより、蓋体８ｅ、８ｆのスムーズな開閉が可能となる。
【００２９】
さらに、蓋体８ｆの凹部１８と、蓋体８ｅの凸部１９の嵌め合いのすり合わせ面は、蓋体８ｅ、８ｆ相互間の回転中心Ｐとほぼ同じ点を中心とした略円弧状の面２０ａ、２０ｂと、開口部を広げるような面２１からなることにより、蓋体８ｆを広げるときに、蓋体８ｅまたは蓋体８ｆに成型時の反りがないときは、図９に示すように、凹部１８と凸部１９の嵌め合いのすり合わせ面２０ａ、２０ｂは当接しないが、蓋体８ｅまたは蓋体８ｆに成型時の反りがあるときは、図１０に示すように、凹部１８と凸部１９の嵌め合いのすり合わせ面２０ａ、２０ｂおよび開口部を広げるような面２１が当接し、成形時の蓋体８ｅまたは蓋体８ｆの反りを徐々に矯正しながら嵌め合わされ、さらにスムーズな開閉が可能となる。
【００３０】
また、凹部１８を洗濯機本体２２の前方側の蓋体８ｅに設け、凸部１９を洗濯機本体２２の後方側の蓋体８ｆに設けることにより、蓋体８ｅ、８ｆを開いた時にも両端の凸部１９が目立つことなく、美観を向上することができる。
