Description

【０００１】
【発明の属する技術分野】
この発明は、家屋内の浴室，トイレ，廊下などの壁面に取り付けられて、老人、病人および身体障害者などの着座，起立および歩行などを補助するのに用いる取手装置に関する。
【０００２】
【従来の技術】
老人や身障者が家屋内を安全に歩行したりあるいは着座および起立するのを補助するために、従来から、浴室，トイレ，廊下などにも手摺りなどとともにまたは独立して、小形の取手装置が複数箇所に亘って並設されていることがある。
【０００３】
この取手装置は、老人や身体障害者がこれを手で握ることによって、着座や起立の助けになったり、歩行姿勢を正常に保ち、かつ安全に歩行できるように構成されており、その構造および壁面への取り付けが、体重を十分に支えるだけの強度を持っている。
【０００４】
【発明が解決しようとする課題】
しかしながら、かかる従来の取手装置の多くは、既存家屋や新築家屋内の廊下、浴室、トイレなどの壁面に固定的に突設されているため、これが健常者などの出入や歩行の妨げになったり、あまり利用されない取手装置は却って、老人や身障者の出入や歩行を妨げたり、危険なものになるという課題があった。
【０００５】
この発明は前記のような従来の課題を解決するものであり、老人や身障者の利用時以外には壁面に沿うように取手部材を収納可能にし、また、利用時には介護人、または老人や身障者本人が簡単な回動操作で取手部材を壁面に対し水平方向に安定に倒すことで、この取手装置を姿勢変更や歩行補助具として利用することができる取手装置を提供することを目的とする。

請求項５の発明にかかる取手装置は、前記筒部材内における前記シャフトの略中間に固定板を固定し、シャフトのこの固定板より一方側である固定板とカム部材との間に前記ばねが配置されてカム部材を付勢しており、他方側である固定板と筒部材に固定され筒部材と一体に回動する回動板との間に、筒部材の回転蓄勢用捩りばねがそれぞれ端部を固定板および回動板に取付けて設けられていることを特徴とする。
【００１２】
請求項６の発明にかかる取手装置は、前記ばねは、シャフトのカム部材が位置する端側とは反対の他端側に固定された固定筒と摺接部材との間に介装されることにより、摺接部材をカム部材方向に付勢することを特徴とする。

請求項７の発明にかかる取手装置は、シャフトのカム部材が位置する端側とは反対の他端側に固定筒が固定され、この固定筒とカム部材の外径が連続する格好に小径とされ、この小径部に捩りばねが、一端をカム部材に、他端を固定筒に固定して外挿され、また、前記固定筒のカム部材側の内径がシャフトの外径より大径とされてシャフトとの間に収納空間を形成し、シャフトのこの収納空間に位置して摺接部材および摺接部材を付勢するばねが設けられていることを特徴とする。
【００１４】
請求項８の発明にかかる取手装置は、筒部材のカム部材が位置する端側とは反対の他端側に固定され筒部材と一体に回動する回動板と前記固定筒との間に粘性グリスが充填されていることを特徴とする。
【００１８】
【発明の実施の形態】
以下、この発明の実施の一形態を図について説明する。図２および図３はこの発明の取手装置を示す正面図および側面図であり、１は家屋の浴室などの壁面２にボルト２ａにより取り付けられたコ字状板からなるブラケットで、このブラケット１に対して回動自在に支持された筒部材３に、パイプ部材などとからなる取手部材４が前方向に突設されている。
【００１９】
図１は前記筒部材３付近の構造を詳細に示す拡大断面図であり、前記コ字状板のブラケット１を構成する一対の支持片１ａには一本のシャフト５が水平に架設されて、両端部がボルト６により固定されている。また、前記支持片１ａの各対向面側には、前記シャフト５の外周を支持するように固定板７がボルト・ナット７ａにより取り付けられている。
【００２０】
前記シャフト５の両端部にはＣ形止め輪８が嵌合されて、シャフト５の固定板７との間で抜け止めがなされている。
【００２１】
９は前記筒部材３の一端（左側）を塞ぐように筒部材に固定して設けられた摺接部材としてのリング状の支持板で、これの中心部を前記シャフト５の一部が微小間隙を介して貫通しており、その筒部材３の他端（右側）は前記固定板７の外周に摺動回動可能に支持されている。従って、支持板９および筒部材３はシャフト５および各固定板７に対して回動可能となっている。
【００２２】
また、前記筒部材３には図４に示すようなストッパ１０が一体に設けられており、その筒部材３に一体の前記取手部材４を、図３のような鎖線位置から水平位置に回動操作したとき、これ以上の回動を規制するように、前記ブラケット１の取付片１ｂに当接するようにされている。
【００２３】
１１は筒部材３内においてシャフト５に対し摺動自在で、かつ回転が拘束されて設けられたカム部材であり、これが筒部材３内に配置されたコイルばね１２により一方の摺動方向に付勢されている。なお、このカム部材１１はシャフト５に対し回転が拘束されるように、非円形面、例えばＤカット面で嵌合されている。
【００２４】
また、そのカム部材１１の前記コイルばね１２とは反対側の側面には、図５および図６に示すように、緩急２段のカム面１１ａ，１１ｂが同一円周上に連続するように２組形成されている。
【００２５】
そして、これらのカム面１１ａ，１１ｂには前記支持板９に突設された一対の摺接片９ａの先端が接触可能となっており、その摺接片９ａは前記筒部材の回動によって前記カム１１ａ，１１ｂ面上を摺動し、前記カム部材１１を、図７および図８に示すようにシャフト５上に移動させるように機能する。
【００２６】
かかる構成になる取手装置では、取手部材４を図２および図３に鎖線で示すように、壁面２に対して垂直状態に保持させている場合には、筒部材３がその保持位置まで回動され、従って、この筒部材３とともに回動される摺接片９ａが前記カム部材１１の傾斜が急なカム面１１ｂ上の最も低い位置に接触している。
【００２７】
これらの摺接片９ａとカム面１１ｂとの接触は前記コイルばね１２の反発力を利用してなされ、当初はその接触（摩擦）抵抗は比較的小さい。しかし、前記取手部材４が金属パイプの重量物で、これが壁面２に対し傾斜操作されても、傾斜が少ないと重量で倒れようとする力は小さいので、その重量に打ち勝って操作する外力を取り除いてもその取手部材４は、その位置で停止できる。
【００２８】
さらに、前記取手部材４をさらに傾動操作して、摺接片９ａがカム面１１ａに乗り上げられると、カム部材１１はさらにシャフト５上を右片へ後退し、コイルばね１２がさらに大きく圧縮される。このため、前記カム面１１ａに対する摺接片９ａの接触抵抗が大きくなり、前記取手部材４が重量で水平方向に倒れようとする力が大きくなるにも拘らず、取手部材４は急激に図２および図３に実線で示すように水平位置に倒れずに、ゆっくりと倒れ、遂には前記ストッパ１０がブラケット１の取付片１ｂに当たる位置で確実に停止する。
【００２９】
一方、図２および図３に示す実線位置から取手部材４を持ち上げて、これを前記壁面２に沿わせるように、つまり鎖線で示す位置に収納させる場合には、取手部材４を前記とは逆の方向に手動操作する。
【００３０】
この操作は、当初は少々重いが、摺接片９ａがカム部材１１を介して受けるコイルばね１２の反発力が次第に小さくなるため、各カム面１１ａ，１１ｂに対する接触抵抗は次第に低下していき、軽快となり、遂には最終的に壁面２に沿う位置に保持される。この時、取手部材４の重量で倒れようとする力より接触抵抗が大きい位置では、取手部材４は停止できる。
【００３１】
なお、この取手部材４の作動特性は前記コイルばね１２による摺接片９ａとカム面１１ｂとの摩擦接触により決定されるので、この接触抵抗を変化させることで、つまり、カム面１１ｂの形状，コイルばね１２の反発力の大きさを任意に設計することで、取手部材４の作動特性を自由に調整できる。
【００３２】
図９は他の実施の形態を示す正面断面図であり、本例はダンパ装置Ｄをさらに付加したものである。
このダンパ装置Ｄは、円筒部１５ａと環状溝１６ａを有し、円筒部１５ａと環状溝１６ａが互に嵌合する２つのリング部材１５，１６からなり、一方のリング部材１５は筒部材３に固定されて筒部材３と一体に回転し、他方のリング部材１６はシャフト５または固定板７の内面側に固定され、この円筒部１５ａと環状溝１６ａが互に嵌合するリング部材１５，１６間に粘性グリス１７を介装されて構成される。
尚、１８は粘性グリス１７の洩れを防止するためのシールリングである。
【００３３】
従って、取手部材４を回動すると、筒部材３に固定されているリング部材１５も回動するため、粘性グリス１７の粘性抵抗を受けることになり、取手部材４が急速に押し下げられて筒部材３も同方向に急速回動されても、前記粘性グリス１７の抵抗作用を受けて、その筒部材３が大きな抵抗を受けてゆっくりと回動することとなる。
【００３４】
この結果、取手部材４の急降下は防止され、これにつかまっている老人や身障者にショックを与えることがなくなり、より安全となる。
【００３５】
一方、前記のようなダンパ装置Ｄにあっては、取手部材４の倒れ方向への回動のみならず、壁面２に沿う方向（収納方向）への回動操作も重くなってしまうことになる。そこで、この壁面（収納方向）への回動操作を軽快にするため、図１０に示すように、捩りばねによる反発力を利用する。
【００３６】
図１０は本発明のさらに他の実施の形態を示す正面断面図であり、前記実施の形態と同一符号は同一物を示す。
同図において、シャフト５の中央付近には固定板２２がピン２１で固定されて設けられており、シャフト５の固定板２２より左側にはカム部材１１を付勢するばね１２が設けられ、右側には筒部材３の回転蓄勢用の捩りばね２３が設けられている。
【００３７】
ばね１２は、固定板２２とカム部材１１の間に位置し、カム部材１１を一方の摺動方向（図１０では左方向）に付勢する。捩りばね２３は、一端が固定板２２に取付けられ、他端は筒部材３の端部に固定され筒部材３と一体に回動する回動板２４に取付けられており、筒部材３の回動で回動板２４も回動するので、筒部材３が回動すると蓄勢される。
【００３８】
従って、取手部材４を倒す方向に回動操作すると、それと共に筒部材３および回動板２４も回動するので、捩りばね２３に反発力が蓄勢され、図２について説明した動作に加えて、前記取手部材４を倒れ方向から壁面２に向かう方向に起立させるときの前記ダンパ装置Ｄおよびカム部材１１との摩擦抵抗による操作力の負担を、捩りばね２３の反発力を利用して軽減することが可能となる。本例によれば、収納方向への操作も容易となる。
【００３９】
この場合において、前記取手部材４が倒れ方向に一気に落ちるのを防止しながら、倒し切ったところで幾分持ち上がって位置が不定とならないように、前記ダンパ装置Ｄおよび捩りばね２３の大きさなどを適切に設計することが望ましい。
【００４０】
図１１は本発明のさらに他の実施の形態を示す正面断面図であり、前記実施の形態と同一符号は同一物を示す。本例は取手部材４の倒れ方向（セット方向）への倒れ勝手（落ち勝手）領域および起立方向（収納方向）への上がり勝手領域を、必要とする特性をもたせ自由に設定できる点に特徴を有する。
【００４１】
図１１において、本例では前述した摺接部材としてのリング状の支持板９の位置に、その一端面が前記のような摺接片９ａではなく、カム面３０ａに形成されているリング状のカム部材３０が設けられている。
シャフト５のこのカム部材３０が位置する側とは反対となる他端側に、固定筒３４が固定されている。この固定筒３４はシャフト５に挿着され、シャフト５との間にピン３５が挿入されシャフト５に固定されている。従って、固定筒３４は回動しない。
【００４２】
そして、前記カム部材３０と固定筒３４には、その外径が連続した格好で小径となる小径部３０ｃ，３４ａが形成され、この小径部３０ｃ，３４ａに捩りばね３３が外挿されている。この捩りばね３３の一端は前記カム部材３０に固定され、他端は前記固定筒３４に固定される。従って、筒部材３が回動すると捩りばね３３には筒部材３を戻す方向への付勢力が蓄勢される。
【００４３】
また、前記固定筒３４の先端側の内径は、シャフト５の外径より大径となっており、シャフト５との間に収納空間３６が形成され、シャフト５のこの収納空間３６に位置して円筒状の摺接部材３１およびこの摺接部材３１を軸方向に付勢するばね３２が挿着されている。
この摺接部材３１は、シャフト５に摺動自在であるが、回転は阻止されている。本例においては、シャフト５にピン３８が設けられ、このピン３８が摺接部材３１に軸方向に設けられた長孔３７に挿入されることによって軸方向に摺動するが回転は阻止されている。
【００４４】
そして、摺接部材３１には摺接片３１ａが突設され、この摺接片３１ａがばね３２の付勢力で前記カム部材３０のカム面３０ａに押圧されて摺接している。
【００４５】
従って、取手部材４を収納状態（起立状態）から水平方向に倒すように回動すると、筒部材３に固定されているリング状のカム部材３０も回動するから、このカム部材３０に一端が固定されている捩りばね３３に反発力が蓄勢される。この反発力は取手部材４を前記とは逆の倒れ方向（水平方向）から収納方向（起立方向）に回動する際の付勢力になる。
【００４６】
一方、摺接部材３１は、ばね３２でその摺接片３１ａがカム部材３０のカム面３０ａに押圧されて摺接しているので、カム部材３０が回動するとカム面３０ａと摺接片３１ａとの間に摩擦抵抗が生ずる。この摩擦抵抗は、カム面３０ａの形状およびばね３２の付勢力を変えることによって自由に調整することができる。例えば、カム面３０ａを図１１に示すように傾斜面と垂直面とで形成すれば、傾斜面では摩擦抵抗が徐々に増大（又はその逆）し、垂直面では変化しない。従って、取手部材４の収納位置（起立位置）で、摺接部材３１の摺接片３１ａをカム面３０ａの傾斜面上の最も低い位置に接触させておき、取手部材４を水平方向に倒すと、カム部材３０ａが回動し摺接片３１ａはカム面３０ａの傾斜面に乗り上げていくので摩擦抵抗が徐々に増大し、取手部材４が重量で水平方向に倒れようとする力が大きくなっても取手部材４は急激に水平に倒れずに、ゆっくりと倒れ、水平面で停止する。この最終的な停止位置は、図３および図４に示すのと同様なストッパ１０で行う。
また、前記カム面３０ａの形状を逆にすれば、前記とは逆の作用となる。
【００４７】
そして、この動作と共に捩りばね３３には取手部材４を収納（起立）する方向への付勢力が蓄勢されるので、収納（起立）方向への回動も容易となり、少しの力で収納できることになる。
【００４８】
このように本実施の形態においては、カム面３０ａの形状及びばね３２の付勢力を変えることによって、倒れ勝手および上がり勝手の領域の特性を自由に設定できると共に、取手部材の収納を容易に行うことができる。
【００４９】
尚、本例の固定板７は、前記したように支持片１ａにボルト・ナット７ａにより固定されるのではなく、固定板７の一端部が支持片１ａに係止することによって取り付けられている。また、図１１における符号１ｃは、本装置の取付用の孔であり、３９は本装置に初期トルクをかけて停止しておくストッパピンであり、４２はシールリングである。
【００５０】
さらに、本例においては、回動板２４と固定筒３４との間４０に粘性グリス４１を充填しダンパ効果をもたせることもできる。
この粘性グリス４１によるダンパーは、例えば収納する際取手部材が勢いよく起き上がり壁面等に当たりはね返るのを防止できる。
また、図９および図１０に示すようなダンパ装置Ｄを設けてもよい。
【００５１】
図１２は本発明のさらに他の実施の形態を示す正面断面図であり、前記実施の形態と同一符号は同一物を示す。本例は、摺接部材３１を付勢するコイルばね３２のばね力（付勢力）の調整を可能とし、取手部材４の作動特性を自由に調整できるようにしたものである。
【００５２】
図１２において、本例ではシャフト５の右端側に調整コマ５２およびスライド部材５１が設けられ、コイルばね３２は摺接部材３１とスライド部材５１との間に位置される。
【００５３】
調整コマ５２は、筒状の内面に雌ねじ５２ａを有するナット状で、シャフト５に回転自在となっている。
スライド部材５１は、シャフト５に摺動自在であるが、回転は阻止されている。本例においては、スライド部材５１に設けられたピン５４が、シャフト５に軸方向に設けられた長孔５３に挿入されることによって軸方向に摺動するが回転は阻止されている。
【００５４】
そして、スライド部材５１の一端側外周面に雄ねじ５１ａが設けられ、この雄ねじ５１ａに前記調整コマ５２の雌ねじ５２ａが螺合されている。従って、調整コマ５２を回転させると、スライド部材５１はシャフト５にそって進展するから、調整コマ５２を回転させスライド部材５１を進出（左方向に移動）させるとコイルばね３２は圧縮され、付勢力は増大し、逆にスライド部材５１を後退（右方向に移動）させるとコイルばね３２は伸長し付勢力は減少する。
【００５５】
しかして、調整コマ５２を回転しコイルばね３２の付勢力が調整できるため、摺接部材３１のカム部材３０への当接力（摩擦抵抗）を調整でき、取手部材４の作動特性を自由に調整できるものである。
【００５６】
この図１２に示す実施の形態は、図１１のコイルばね３２の右側にスライド部材５１および調整コマ５２を設けた格好であるが、図１および図９に示す実施の形態では、コイルばね１２の右側に、図１０に示す実施の形態では、コイルばね１２と固定板２２の間に、また、図１１に示す実施の形態では、ばね３２の右側に、前記図１２に示すと同様の調整手段を設けることによって、ばね１２，３２の付勢力の調整ができる。
【００５７】
また、コイルばね１２および３２の付勢力の調整は、前記実施の形態に限定されるものではない。例えば、スライド部材５１をシャフト５に直接螺合させてもよい。
さらに、図１に示すよう摺接部材９が筒部材３に固定され筒部材３と一体に回動し、カム部材１１がシャフト５にそって摺動し、このカム部材１１をばね１２で付勢する構造のものにあっては、このカム部材を付勢するばね１２に、前記図１２に示すような調整手段を設けるものである。
【００５８】
尚、図１２に示す実施の形態によれば、取手部材４に初期トルクをかけて、カム部材３０と摺接部材３１との間でストップ（例えば、カム部材３０の凹部に摺接部材３１の突部を嵌合させる）させることができるため、図１１に示すようなストッパピン３９は不要となる。
【００５９】
また、図１２において符号５０は、カラー部材であって、ばね３２と３３との間に介在し、ばね３２とばね３３とが接触し異音を発生するのを防止するものである。このカラー部材５０の材料としては、合成樹脂材およびゴム材等を挙げることができる。
【００６０】
【発明の効果】
以上のように、請求項１記載の発明によれば、ブラケット両端の一対の支持片に両端部が固定されることにより支持片に掛け渡された状態となってブラケットに支持固定されたシャフトと、このシャフトが貫通した状態となっており、ブラケットの一対の支持片の間で一定の角度領域内で回転自在に支持された筒部材と、該筒部材に固定して突設された取手部材と、端面にカム面が形成されたカム部材と、このカム面に摺接する摺接部材と、カム面と摺接部材とが相互に接触するように付勢するばねと、このばねの付勢力を調整する調整手段とを備え、カム部材または摺接部材のいずれか一方が筒部材と一体に回動可能となっているため、摺接部材とカム部材のカム面との間の摩擦抵抗は、カム面の形状およびばねの付勢力を変えることによって自由に調整でき、取手部材の倒れ勝手および上がり勝手領域の特性を自由に設定できる。しかも、老人や身障者の利用時以外には壁面に沿うように取手部材を収納可能にし、また、利用時には介護人または老人や身障者本人が簡単な回動操作で取手部材を壁面に対し水平方向に安定に倒すことで、この取手部材を姿勢変更や歩行補助具として利用することができるという効果が得られる。
また、調整手段が、回転が阻止された状態で前記ばねに対応して設けられ、シャフトの軸方向に摺動自在なスライド部材と、スライド部材に螺合し、回転によってスライド部材をばねに対して進退させる調整コマとを有して構成されるため、カム部材あるいは摺接部材を付勢するばねの付勢力の調整は、調整コマを回転するだけでよく、取手部材の作動特性の調整が容易にできる効果を有している。
【００６２】
また、請求項２記載の発明によれば、前記筒部材およびシャフト間には、一方に円筒部、他方にこの円筒部が嵌入する環状溝が設けられ、円筒部と環状溝が互に嵌合する２つのリング部材の、一方が前記筒部材に固定され筒部材と一体に回転し、他方が前記シャフトに固定され、この円筒部と環状溝が互に嵌合するリング部材間に粘性グリスを介在したダンパ装置を介装するように構成したので、特に、取手部材の傾動途中からの急速な傾動落下を防止でき、老人や身障者の転倒事故などを未然に回避できるという効果が得られる。
【００６３】
また、請求項３記載の発明によれば、前記ばねは、筒部材内において前記シャフトのカム部材と筒部材の端部に位置する固定板との間に外挿されることにより、カム部材を摺接部材方向に付勢しているので、部品が取手装置内に収納され安全であるし、コンパクトにできる。
【００６４】
また、請求項４記載の発明によれば、前記筒部材およびシャフト間には、前記筒部材の回転蓄勢用捩りばねを介装するように構成したので、取手部材の起立動作（収納動作）を助勢させることができ、これによって取手部材の緩慢な倒れ動作と迅速な起立動作（収納動作）を共に効率的に実現できるという効果が得られる。従って、老人や身障者等でも容易に操作することができる。
【００６５】
また、請求項５記載の発明によれば、前記筒部材内における前記シャフトの略中間に固定板を固定し、シャフトのこの固定板より一方側である固定板とカム部材との間に前記ばねが配置されてカム部材を付勢しており、他方側である固定板と筒部材に固定され筒部材と一体に回動する回動板との間に、筒部材の回転蓄勢用捩りばねがそれぞれ端部を固定板および回動板に取付けて設けられているので、起立動作（収納動作）を助勢して軽くできると共に、部品が取手装置内に収納され安全であるし、装置全体をコンパクトにできる。
【００６６】
また、請求項６記載の発明によれば、前記ばねは、シャフトのカム部材が位置する端側とは反対の他端側に固定された固定筒と摺接部材との間に介装されることにより、摺接部材をカム部材方向に付勢するので、部品が取手装置内に収納され安全であるし、コンパクトにでき、かつばね特性を有効に作用させることができる。
【００６７】
また、請求項７記載の発明によれば、シャフトのカム部材が位置する端側とは反対の他端側に固定筒が固定され、この固定筒とカム部材の外径が連続する格好に小径とされ、この小径部に捩りばねが、一端をカム部材に、他端を固定筒に固定して外挿され、また、前記固定筒のカム部材側の内径がシャフトの外径より大径とされてシャフトとの間に収納空間を形成し、シャフトのこの収納空間に位置して摺接部材および摺接部材を付勢するばねが設けられているため、カム部材が回動するとカム面と摺接部材との間に摩擦抵抗が生じ、この摩擦抵抗は、カム面の形状およびばねの付勢力を変えることによって自由に調整でき、かつ取手部材の回動で捩りばねには、戻り方向（起立方向）への付勢力が蓄勢される。従って、取手部材の倒れ勝手および上がり（起立）勝手領域の特性を自由に設定できるし、取手部材の収納（起立）操作も容易に行うことができる。このことにより老人や身障者等でも容易に操作できる取手装置を提供できるし、好みの特性を有する取手装置とすることができる。
【００６８】
また、請求項８記載の発明によれば、筒部材のカム部材が位置する端側とは反対の他端側に固定され筒部材と一体に回動する回動板と前記固定筒との間に粘性グリスが充填されているため、取手部材の回動にダンパ効果を作用させることができると共に、取手部材の回動終端や壁面に当った際のはね返りを防止できる。

[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 2 and 3 are a front view and a side view showing the handle device of the present invention. Reference numeral 1 denotes a bracket made of a U-shaped plate attached to a wall 2 of a bathroom or the like of a house with bolts 2a. A handle member 4 composed of a pipe member or the like is provided on the cylindrical member 3 rotatably supported so as to protrude forward.
[0019]
FIG. 1 is an enlarged sectional view showing the structure in the vicinity of the cylindrical member 3 in detail. One shaft 5 is horizontally mounted on a pair of support pieces 1a constituting the bracket 1 of the U-shaped plate. Both ends are fixed by bolts 6. A fixing plate 7 is attached to each of the opposing surfaces of the support piece 1a by bolts and nuts 7a so as to support the outer periphery of the shaft 5.
[0020]
C-shaped retaining rings 8 are fitted to both ends of the shaft 5 to prevent the shaft 5 from coming off with respect to the fixed plate 7.
[0021]
Reference numeral 9 denotes a ring-shaped support plate as a sliding contact member fixed to the cylindrical member so as to close one end (left side) of the cylindrical member 3. The other end (right side) of the cylindrical member 3 is slidably supported on the outer periphery of the fixed plate 7. Therefore, the support plate 9 and the cylindrical member 3 are rotatable with respect to the shaft 5 and each fixed plate 7.
[0022]
Further, a stopper 10 as shown in FIG. 4 is provided integrally with the tubular member 3, and the handle member 4 integrated with the tubular member 3 is rotated from a chain line position as shown in FIG. When operated, it comes into contact with the mounting piece 1b of the bracket 1 so as to restrict further rotation.
[0023]
Reference numeral 11 denotes a cam member slidable relative to the shaft 5 in the tubular member 3 and provided with its rotation restricted. The cam member 11 is attached in one sliding direction by a coil spring 12 disposed in the tubular member 3. It is being rushed. The cam member 11 is fitted with a non-circular surface, for example, a D-cut surface so that the rotation of the cam member 11 is restricted with respect to the shaft 5.
[0024]
As shown in FIGS. 5 and 6, on the side surface of the cam member 11 opposite to the coil spring 12, two gentle and steep cam surfaces 11a and 11b are continuously formed on the same circumference. A pair is formed.
[0025]
The tips of a pair of sliding contact pieces 9a protruding from the support plate 9 can come into contact with these cam surfaces 11a and 11b, and the sliding contact pieces 9a are rotated by rotation of the cylindrical member. The cam member 11 slides on the surfaces of the cams 11a and 11b, and functions to move the cam member 11 onto the shaft 5 as shown in FIGS.
[0026]
In the handle device having such a configuration, when the handle member 4 is held vertically with respect to the wall surface 2 as shown by a chain line in FIGS. 2 and 3, the cylindrical member 3 is rotated to the holding position. Therefore, the sliding contact piece 9a rotated together with the cylindrical member 3 is in contact with the lowest position on the cam surface 11b where the cam member 11 is steeply inclined.
[0027]
The contact between the sliding contact piece 9a and the cam surface 11b is made by using the repulsive force of the coil spring 12, and the contact (friction) resistance is initially relatively small. However, even if the handle member 4 is a heavy metal pipe and is tilted with respect to the wall surface 2, if the tilt is small, the force to fall down by weight is small. Even so, the handle member 4 can be stopped at that position.
[0028]
Further, when the handle member 4 is further tilted and the sliding contact piece 9a rides on the cam surface 11a, the cam member 11 further retreats to the right side on the shaft 5, and the coil spring 12 is further compressed. . For this reason, the contact resistance of the sliding contact piece 9a to the cam surface 11a increases, and the handle member 4 suddenly moves as shown in FIG. And, as shown by the solid line in FIG. 3, it does not fall to the horizontal position, but slowly falls, and finally stops at the position where the stopper 10 hits the mounting piece 1 b of the bracket 1.
[0029]
On the other hand, when the handle member 4 is lifted from the solid line position shown in FIG. 2 and FIG. Operate manually in the direction of.
[0030]
This operation is a little heavy at first, but since the repulsive force of the coil spring 12 received by the sliding contact piece 9a via the cam member 11 gradually decreases, the contact resistance to each of the cam surfaces 11a and 11b gradually decreases. It becomes light, and is finally held at a position along the wall surface 2. At this time, the handle member 4 can be stopped at a position where the contact resistance is greater than the force of the handle member 4 trying to fall due to its weight.
[0031]
Since the operating characteristics of the handle member 4 are determined by the frictional contact between the sliding contact piece 9a and the cam surface 11b by the coil spring 12, changing the contact resistance, that is, the shape of the cam surface 11b, The operating characteristics of the handle member 4 can be freely adjusted by arbitrarily designing the magnitude of the repulsive force of the coil spring 12.
[0032]
FIG. 9 is a front sectional view showing another embodiment. In this embodiment, a damper device D is further added.
This damper device D has a cylindrical portion 15a and an annular groove 16a, and is composed of two ring members 15 and 16 in which the cylindrical portion 15a and the annular groove 16a are fitted to each other. The ring member 16 is fixed and rotates integrally with the cylindrical member 3, and the other ring member 16 is fixed to the inner surface of the shaft 5 or the fixed plate 7, and the cylindrical members 15 a and the annular grooves 16 a are fitted to each other. The viscous grease 17 is interposed therebetween.
Reference numeral 18 denotes a seal ring for preventing the viscous grease 17 from leaking.
[0033]
Therefore, when the handle member 4 is rotated, the ring member 15 fixed to the cylindrical member 3 is also rotated, so that it receives the viscous resistance of the viscous grease 17, and the handle member 4 is rapidly pushed down and the cylindrical member 3 is pressed. Even if the cylinder 3 is rapidly rotated in the same direction, the cylindrical member 3 receives a large resistance due to the resistance action of the viscous grease 17 and slowly rotates.
[0034]
As a result, the descent of the handle member 4 is prevented, and no shock is given to an elderly person or a handicapped person who is gripped by the handle member 4, which is more secure.
[0035]
On the other hand, in the above-described damper device D, not only the turning in the falling direction of the handle member 4 but also the turning operation in the direction (storage direction) along the wall surface 2 becomes heavy. . Therefore, as shown in FIG. 10, the repulsive force of the torsion spring is used to make the rotation operation to the wall surface (the storing direction) light.
[0036]
FIG. 10 is a front sectional view showing still another embodiment of the present invention, and the same reference numerals as those of the above-mentioned embodiment indicate the same parts.
In the same figure, a fixed plate 22 is provided near the center of the shaft 5 with a pin 21 fixed thereto, and a spring 12 for urging the cam member 11 is provided on the left side of the fixed plate 22 of the shaft 5, and a right side. Is provided with a torsion spring 23 for rotationally accumulating the cylindrical member 3.
[0037]
The spring 12 is located between the fixed plate 22 and the cam member 11, and biases the cam member 11 in one sliding direction (left direction in FIG. 10). One end of the torsion spring 23 is attached to the fixed plate 22, and the other end is attached to a rotating plate 24 that is fixed to an end of the cylindrical member 3 and rotates integrally with the cylindrical member 3. Since the rotating plate 24 also rotates by the movement, when the cylindrical member 3 rotates, the rotation is accumulated.
[0038]
Therefore, when the handle member 4 is turned in the tilting direction, the tubular member 3 and the turning plate 24 are also turned together with the turning operation, so that a repulsive force is accumulated in the torsion spring 23, and in addition to the operation described with reference to FIG. The burden of operating force due to frictional resistance between the damper device D and the cam member 11 when the handle member 4 is raised in the direction from the falling direction toward the wall surface 2 is reduced by using the repulsive force of the torsion spring 23. It becomes possible. According to this example, the operation in the storage direction becomes easy.
[0039]
In this case, the size of the damper device D and the size of the torsion spring 23 are appropriately adjusted so that the handle member 4 is prevented from dropping in a falling direction at a stretch, and the position is not fixed and the position is not fixed. It is desirable to design it.
[0040]
FIG. 11 is a front sectional view showing still another embodiment of the present invention, and the same reference numerals as those of the above-mentioned embodiment indicate the same parts. The present embodiment is characterized in that a region in which the handle member 4 can fall in the falling direction (set direction) and a region in which the handle member 4 can rise in the standing direction (storage direction) can be freely set with necessary characteristics. Have.
[0041]
In FIG. 11, in this example, at the position of the ring-shaped support plate 9 serving as the sliding contact member described above, one end surface thereof is formed not on the sliding contact piece 9a but on the cam surface 30a. A cam member 30 is provided.
A fixed cylinder 34 is fixed to the other end of the shaft 5 opposite to the side where the cam member 30 is located. The fixed cylinder 34 is inserted into the shaft 5, and a pin 35 is inserted between the fixed cylinder 34 and the shaft 5 to be fixed to the shaft 5. Therefore, the fixed cylinder 34 does not rotate.
[0042]
The cam member 30 and the fixed cylinder 34 are formed with small diameter portions 30c and 34a having successively smaller outer diameters, and the torsion spring 33 is externally inserted into the small diameter portions 30c and 34a. One end of the torsion spring 33 is fixed to the cam member 30, and the other end is fixed to the fixed cylinder 34. Therefore, when the cylindrical member 3 rotates, the torsional spring 33 stores an urging force in the direction of returning the cylindrical member 3.
[0043]
The inner diameter of the fixed cylinder 34 on the distal end side is larger than the outer diameter of the shaft 5, and a storage space 36 is formed between the fixed cylinder 34 and the shaft 5. A cylindrical sliding contact member 31 and a spring 32 for urging the sliding contact member 31 in the axial direction are inserted.
The sliding member 31 is slidable on the shaft 5, but is prevented from rotating. In the present example, a pin 38 is provided on the shaft 5 and the pin 38 is inserted into a long hole 37 provided in the sliding member 31 in the axial direction, so that the pin 5 slides in the axial direction but is prevented from rotating. I have.
[0044]
The sliding contact member 31 is provided with a sliding contact piece 31a protruding therefrom. The sliding contact piece 31a is pressed against the cam surface 30a of the cam member 30 by the urging force of the spring 32 to make sliding contact.
[0045]
Therefore, when the handle member 4 is turned so as to be tilted in the horizontal direction from the stored state (standing state), the ring-shaped cam member 30 fixed to the tubular member 3 also turns. Repulsive force is accumulated in the fixed torsion spring 33. This repulsive force is an urging force when the handle member 4 is rotated from the opposite falling direction (horizontal direction) to the storing direction (standing direction).
[0046]
On the other hand, the sliding member 31 is pressed by the spring 32 against the cam surface 30a of the cam member 30 and is in sliding contact with the sliding member 31. Therefore, when the cam member 30 rotates, the cam surface 30a and the sliding member 31a Frictional resistance occurs during This frictional resistance can be freely adjusted by changing the shape of the cam surface 30a and the urging force of the spring 32. For example, if the cam surface 30a is formed of an inclined surface and a vertical surface as shown in FIG. 11, the frictional resistance gradually increases on the inclined surface (or vice versa) and does not change on the vertical surface. Therefore, when the sliding contact piece 31a of the sliding contact member 31 is brought into contact with the lowest position on the inclined surface of the cam surface 30a at the storage position (standing position) of the handle member 4, and the handle member 4 is tilted in the horizontal direction. Since the cam member 30a rotates and the sliding contact piece 31a rides on the inclined surface of the cam surface 30a, the frictional resistance gradually increases, and the force of the handle member 4 to fall in the horizontal direction by weight increases. Also, the handle member 4 does not suddenly fall horizontally but falls slowly and stops on a horizontal plane. This final stop position is performed by a stopper 10 similar to that shown in FIGS.
If the shape of the cam surface 30a is reversed, the operation will be the reverse of the above.
[0047]
With this operation, the torsional spring 33 accumulates the urging force in the direction in which the handle member 4 is stored (erected), so that the torsion spring 33 can be easily rotated in the storage (erected) direction and can be stored with a little force. become.
[0048]
As described above, in the present embodiment, by changing the shape of the cam surface 30a and the biasing force of the spring 32, the characteristics of the falling and rising regions can be freely set, and the handle member can be easily stored. be able to.
[0049]
The fixing plate 7 of this embodiment is attached to the supporting piece 1a by fixing one end of the fixing plate 7 to the supporting piece 1a, instead of being fixed to the supporting piece 1a by the bolt / nut 7a as described above. . Further, reference numeral 1c in FIG. 11 denotes a hole for mounting the apparatus, 39 denotes a stopper pin for stopping the apparatus by applying an initial torque, and 42 denotes a seal ring.
[0050]
Further, in this embodiment, the space 40 between the rotating plate 24 and the fixed cylinder 34 can be filled with viscous grease 41 to have a damper effect.
The damper made of the viscous grease 41 can prevent the handle member from rising vigorously and hitting the wall surface or the like when being stored, for example.
Further, a damper device D as shown in FIGS. 9 and 10 may be provided.
[0051]
FIG. 12 is a front sectional view showing still another embodiment of the present invention. In this embodiment, the spring force (biasing force) of the coil spring 32 for biasing the sliding contact member 31 can be adjusted, and the operating characteristics of the handle member 4 can be freely adjusted.
[0052]
12, in this example, an adjustment piece 52 and a slide member 51 are provided on the right end side of the shaft 5, and the coil spring 32 is located between the slide contact member 31 and the slide member 51.
[0053]
The adjustment piece 52 has a nut shape having a female screw 52 a on a cylindrical inner surface, and is rotatable around the shaft 5.
The slide member 51 is slidable on the shaft 5, but is prevented from rotating. In this example, the pin 54 provided on the slide member 51 is inserted into the elongated hole 53 provided in the shaft 5 in the axial direction, so that the pin 54 slides in the axial direction but is prevented from rotating.
[0054]
A male screw 51a is provided on the outer peripheral surface on one end side of the slide member 51, and a female screw 52a of the adjustment piece 52 is screwed to the male screw 51a. Therefore, when the adjustment piece 52 is rotated, the slide member 51 advances along the shaft 5. Therefore, when the adjustment piece 52 is rotated and the slide member 51 is advanced (moved to the left), the coil spring 32 is compressed and attached. The biasing force increases, and conversely, when the slide member 51 is retracted (moved to the right), the coil spring 32 expands and the biasing force decreases.
[0055]
Since the urging force of the coil spring 32 can be adjusted by rotating the adjustment piece 52, the contact force (friction resistance) of the sliding contact member 31 against the cam member 30 can be adjusted, and the operating characteristics of the handle member 4 can be freely adjusted. You can do it.
[0056]
In the embodiment shown in FIG. 12, a slide member 51 and an adjustment piece 52 are provided on the right side of the coil spring 32 in FIG. 11, but in the embodiment shown in FIGS. On the right side, between the coil spring 12 and the fixed plate 22 in the embodiment shown in FIG. 10, and on the right side of the spring 32 in the embodiment shown in FIG. 11, the same adjusting means as shown in FIG. Is provided, the biasing force of the springs 12, 32 can be adjusted.
[0057]
The adjustment of the biasing force of the coil springs 12 and 32 is not limited to the above embodiment. For example, the slide member 51 may be directly screwed to the shaft 5.
Further, as shown in FIG. 1, the sliding contact member 9 is fixed to the cylindrical member 3 and rotates integrally with the cylindrical member 3, and the cam member 11 slides along the shaft 5, and the cam member 11 is attached by the spring 12. In the case of the biasing structure, the spring 12 for biasing the cam member is provided with adjusting means as shown in FIG.
[0058]
In addition, according to the embodiment shown in FIG. 12, an initial torque is applied to the handle member 4 to stop between the cam member 30 and the sliding contact member 31 (for example, the sliding contact member 31 Since the protrusions can be fitted), the stopper pin 39 as shown in FIG. 11 is not required.
[0059]
In FIG. 12, reference numeral 50 denotes a collar member interposed between the springs 32 and 33 to prevent the spring 32 and the spring 33 from coming into contact with each other and generating abnormal noise. Examples of the material of the collar member 50 include a synthetic resin material and a rubber material.
[0060]
