Description

【０００１】
【発明の属する技術分野】
本発明は、便座及び便蓋を設けた便器の背凭れ構造に関するものである。
【０００２】
【従来の技術】
近年、トイレルームでくつろいだり、あるいは高齢者や身体障害者の身体への負担を軽減するため、便座を有する便器（いわゆる洋式便器）に背凭れ部やアームレスト等を設けたものが使用されている。このような便器に背凭れ部を設けるには、便蓋を取り外して替わりに背凭れ部を取付けたりしていた（例えば特許文献１参照）。つまり、このような便器においては、便蓋は便器の不使用時には前方に傾倒して便器上（便座上）に載置し、便器に着座して使用する時には、便蓋を後方に起立させて着座した使用者が背凭れ部に凭れられるように便蓋を背凭れ部よりも後方に位置させるものであり、このため、便蓋を回動する際に背凭れ部と干渉してしまい、背凭れ部を設けるには便蓋を取り外す必要があった。
【０００３】
しかし、便蓋を設けないと、便器内が常時見えて見栄えが悪い、便器の内部上面に埃が溜まる、便座にヒータを設けてある場合には便座から無駄に放熱されてしまう、といった問題があって好ましくないものであった。そこで、背凭れ部を可動にして便蓋との干渉を回避するものが考えられた（例えば特許文献２参照）。
【０００４】
このものは、トイレルームの壁に支持部材を取り付けると共に、この支持部材に背凭れ部を回動自在に設け、便蓋を回動する際に該便蓋と干渉しないように背凭れ部を便蓋の回動軌跡よりも上方に位置させ、便蓋の通過後に背凭れ部を所定の位置に配置するものである。
【０００５】
しかしながら、このものにあっては、便蓋を通過させる際に背凭れ部を上方に位置させておき、便蓋を通過後に背凭れ部を所定位置に配置するため、両手を使って便蓋と背凭れ部とをそれぞれ動かすか、あるいは片手で行う場合には便蓋を動かした後に背凭れ部を動かす必要があって、手間がかかるものであった。
【０００６】
また、背凭れ部を支持する支持部材をトイレルームの壁に取り付けるため、壁を補強する必要があると共に後付けで背凭れ部を設けるのが困難でコストが高くつくものであった。

【発明が解決しようとする課題】
本発明はこのような点に鑑みてなされたものであり、その目的とするところは、背凭れ部を便蓋と干渉しないように設けると共に、便蓋を回動する際に背凭れ部を移動したりする手間がかからず、背凭れ部を設けるのにトイレルームの壁を補強したりする必要のない背凭れ構造を提供することを課題とするものである。
【０００９】
【課題を解決するための手段】
上記課題を解決するため、請求項１に係る背凭れ構造は、便座１及び便蓋２を設けた便器３の背凭れ構造であって、便器３の両側端部よりそれぞれ略上方に向けて支持腕４を上記便蓋２の回動軌跡外に位置するように突設すると共に該両支持腕４の上端部間に背凭れ部５を回動自在に設け、上記便蓋２の回動先端２１を背凭れ部５の前方又は後方の一方側から他方側へ回動する際に該便蓋２の回動先端２１が背凭れ部５の下端部５１を他方側へ押すと共に便蓋２の回動先端２１が背凭れ部５の下端部５１よりも他方側へ移動した時に背凭れ部５の下端部５１が自重で一方側に回動して戻るように背凭れ部５の回動軸５２を便蓋２の回動軌跡の上方に配置し且つ背凭れ部５の下端部５１を便蓋２の回動軌跡内に配置して成ることを特徴とするものである。このような構成とすることで、背凭れ部５を設けてあっても便蓋２を背凭れ部５と干渉することなく背凭れ部５の一方から他方へと移動させることができて、更にこの時、便蓋２のみを手で回動すればよいため手間がかからないものであり、また、背凭れ部５を支持腕４を介して便器３に取り付けるものであるため、トイレルームの壁を補強したりする必要がないと共に後付けでも容易に背凭れ部５を設けることができる。
【００１０】
また、請求項２に係る背凭れ構造は、便座１及び便蓋２を設けた便器３の背凭れ構造であって、便器３の後端部より略上方に向けて支持腕４を突設すると共に該支持腕４の上端部に背凭れ部５を回動自在に設け、前記背凭れ部５をその回動先端２１が前方略水平を向いた姿勢を無負荷状態とすると共に便座１に着座した身体にて前記無負荷状態から回動先端２１が下方に押された時に該回動先端２１が上記支持腕４の前方に起立した便蓋２よりも前方に位置するように付勢して成ることを特徴とするものである。このような構成とすることで、背凭れ部５を設けてあっても便蓋２を背凭れ部５と干渉することなく移動（起立、傾動）させることができて、更にこの時、便蓋２のみを手で回動すればよくて、両手でそれぞれ便蓋２と背凭れ部５を動かしたり片手で便蓋２と背凭れ部５とを順に動かしたりする必要がなく、手間がかからない。また、背凭れ部５を取付プレート９を介して便器３に取り付けるものであるため、トイレルームの壁を補強したりする必要がないと共に後付けでも容易に背凭れ部５を設けることができる。
【００１１】
また、請求項３の発明は、請求項２の発明において、便器３の後部に略Ｔ字又は略Ｄ字又は略Ｕ字状をした取付プレート９を取付けると共に該取付プレート９に支持腕４を取り付けて成ることを特徴とするものである。このような構成とすることで、支持腕４を取り付けるための取付プレート９を容易に便器３に設けることができる。
【００１２】
また、請求項４に係る背凭れ構造は、便座１及び便蓋２を設けた便器３の背凭れ構造であって、便器３の両側端部よりそれぞれ略上方に向けて支持腕４を上記便蓋２の回動軌跡外に位置するように突設すると共に、前記支持腕４の上端部にそれぞれ前後方向を長手方向とするアームレスト部７１及び該アームレスト部７１の後端部から略直角に突出する背凭れ部５からなる略Ｌ字状をした可動部材７を設け、前記背凭れ部５の使用時に両可動部材７の背凭れ部５がその回動先端５３がほぼ対向する姿勢となると共に不使用時に両可動部材７全体が便蓋２の回動軌跡外に位置するように可動部材７をアームレスト部７１の長手方向廻りに回動自在として成ることを特徴とするものである。このような構成とすることで、背凭れ部７２を設けてあっても便蓋２を背凭れ部７２と干渉することなく移動（起立、傾動）させることができる。また、背凭れ部５を取付プレート９を介して便器３に取り付けるものであるため、トイレルームの壁を補強したりする必要がないと共に後付けでも容易に背凭れ部５を設けることができる。
【００１３】
【発明の実施の形態】
以下、本発明を図１乃至図５に示す実施形態に基づいて説明する。
【００１４】
便器３は、図１等に示すように、上方に開口したいわゆる洋式便器で、この便器３の上端面の前記開口の縁部に便座１を載置可能となるように便座１をその後端部を便器３の上端面の後部に枢支し、便器３に載置した便座１上に便蓋２が載置可能となるように便蓋２も同様に便器３の後部に枢支してある。
【００１５】
便器３の両側端部にはそれぞれ後述する支持腕４を接続するための接続部材６が設けてある。接続部材６は、本実施形態では図４に示すように板状の上横片６１及び縦片６２からなる正面視略逆Ｌ字状の金属製のもので、上横片６１を便器３の開口の縁部に載置して縦片６２を便器３の側端部に沿わせて配置し、ボルト・ナットにて便器３に固定するものである。なお、便器３への固定は、便器３にボルト挿通孔を穿設すると共に接続部材６にもボルト挿通孔を穿設し、前記両ボルト挿通孔にボルトを挿通してナットを螺着しているが、特にこれに限定されない。
【００１６】
接続部材６の縦片６２には、支持腕４が取り付けられる軸部６３が外側方に向けて突設してある。この軸部６３は、軸方向視の形状が外周にギア状の歯部６４を有する形状となっており、この歯部６４が支持腕４と噛み合って支持腕４が回動しないように固定される。
【００１７】
支持腕４は、図１，図４等に示すように、接続部材６に取り付けられる取付部４３と、取付部４３から略上方に向けて突出する支持腕本体４１と、支持腕本体４１の上端部から略水平に突出する支持片４２とからなる。支持腕本体４１は、便座１及び便蓋２の回動軌跡よりも水平方向の外側に配置されると共に、支持片４２は便座１及び便蓋２の回動軌跡の上方に配置され、便座１及び便蓋２と支持腕４とは干渉しない配置となっている。
【００１８】
支持腕４の取付部４３には、上記接続部材６の軸部６３が挿入される挿入部４４と、その挿入部４４の内周に内歯部４５が形成してあり、歯部６４と内歯部４５とが噛み合うように軸部６３を挿入部４４に挿入することで、支持腕４が回動しないように接続部材６に固定される。
【００１９】
また、本実施形態では、図１，図５等に示すように、支持腕４とは別にアームレスト８を取り付けてある。図５に、便器３に固定した接続部材６への支持腕４及びアームレスト８の接続を説明する説明図を示す。図５中の８０はアームレスト８の軸部６３への取付部、８１は皿ばね、８２は軸受筒、８３は平座金、８４はスプリング座金、８５は取付けボルト、８６はキャップを示す。このアームレスト８は、軸受筒８２と取付部８０との間で摺動可能となっていて、アームレスト８を回動することができる。
【００２０】
このような支持腕４には、両支持腕４の上端部の支持片４２間に背凭れ部５が回動自在に設けられる。本実施形態の背凭れ部５は、正面視において上下に長い長方形状をしたもので、上下の中央部の側面に軸受部５２が設けてあり、支持腕４の支持片４２の先端が軸受部５２に挿入されて背凭れ部５が軸受部５２を軸として回動自在となる。
【００２１】
この背凭れ部５は、支持腕４の支持片４２に枢支されて自重以外の力が加わっていない状態では、図１に示すように上下が長手方向となるように起立し、その下端部５１が便蓋２の回動軌跡内に位置した状態となっている。なお、このように起立させるには、下端部５１に錘を埋設する、軸受部５２においてばね付勢する等、どのような方法であってもよい。
【００２２】
背凭れ部５の動作について説明する。使用者が着座するために図１に示す状態から便蓋２の回動先端２１を上方に起立させて回動させると、図２に示すように、便蓋２の回動先端２１が背凭れ部５の下端部５１を後方へ押して背凭れ部５が矢印の方向に回動し、便蓋２の回動先端２１が背凭れ部５の下端部５１よりも後方へ移動すると、図３に示すように矢印の方向に回動して再び起立した状態に戻り、便蓋２の前方に位置して便座１に着座した使用者が背を背凭れ部５に凭れられるようになる。
【００２３】
また、使用後に便蓋２を便座１上に載置する場合には、図３に示す状態から便蓋２の回動先端２１を前方に傾倒して回動させ、便蓋２の回動先端２１が背凭れ部５の下端部５１を前方へ押して背凭れ部５が回動し、便蓋２の回動先端２１が背凭れ部５の下端部５１よりも前方へ移動すると、再び図１に示すように起立した状態に戻り、便蓋２が便座１上に載置される。
【００２４】
以上のような構成によれば、背凭れ部５を設けてあっても便蓋２を背凭れ部５と干渉することなく背凭れ部５の一方から他方（前方から後方又は、後方から前方）へと移動させることができて、更にこの時、便蓋２のみを手で回動すればよくて、両手でそれぞれ便蓋２と背凭れ部５を動かしたり片手で便蓋２と背凭れ部５とを順に動かしたりする必要がなく、手間がかからない。
【００２５】
また、背凭れ部５を接続部材６及び支持腕４を介して便器３に取り付けるものであるため、トイレルームの壁を補強したりする必要がないと共に後付けでも容易に背凭れ部５を設けることができる。
【００２６】
次に、他の実施形態について図６乃至図８に基づいて説明する。なお、上実施形態と同様の部分については同符号を付して説明を省略し、主に異なる部分についてのみ説明する。
【００２７】
本実施形態では、便器３の後端部より略上方に向けて支持腕４を突設してあり、支持腕４の上端部に凹凸係合等によって背凭れ部５を回動自在に設けてある。
【００２８】
便器３の上端面の後部には、支持腕４を取り付けるための取付プレート９が設けてある。取付プレート９は、本実施形態では図８（ａ）に示す略Ｄ字型、図８（ｂ）に示す略Ｔ字型、図８（ｃ）に示す略Ｕ字型のいずれかのもので、前端部の両側端部に便器３への取付部９１を設けると共に、後端部に支持腕４の取付部９２を設けてある。取付プレート９の便器３への取り付けは、上実施形態の接続部材６の便器３への取り付けと同様にボルト・ナットで行い、支持腕４の取付プレート９への取り付けもボルト・ナットにて行う。
【００２９】
背凭れ部５は、自重以外の力が加わっていない無負荷状態において、図６（ａ）及び図７に示すように回動先端５１が前方略水平を向く姿勢となるように枢支部のばね５４によってばね付勢される。
【００３０】
背凭れ部５の動作について説明する。使用者は、無負荷状態において便蓋２を回動して支持腕４の前方に起立させる。そして、使用者は便座１の上に着座し、背で背凭れ部５の回動先端５１を下方に回動させることで、図６（ｂ）に示すように背凭れ部５が下方に回動して支持腕４の前方に位置し、背凭れ部５の前面に凭れられるようになる。
【００３１】
以上のような構成によれば、背凭れ部５を設けてあっても便蓋２を背凭れ部５と干渉することなく移動（起立、傾動）させることができて、更にこの時、便蓋２のみを手で回動すればよくて、両手でそれぞれ便蓋２と背凭れ部５を動かしたり片手で便蓋２と背凭れ部５とを順に動かしたりする必要がなく、手間がかからない。また、背凭れ部５を取付プレート９を介して便器３に取り付けるものであるため、トイレルームの壁を補強したりする必要がないと共に後付けでも容易に背凭れ部５を設けることができる。
【００３２】
次に、更に他の実施形態について図９乃至図１１に基づいて説明する。なお、上実施形態と同様の部分については同符号を付して説明を省略し、主に異なる部分についてのみ説明する。
【００３３】
本実施形態では、図１乃至図５に示す実施形態と比べて支持腕４の上端部が低くなるように形成し、この支持腕４の上端部にアームレストと背凭れとを兼ねた可動部材７を回動自在に設けるものである。
【００３４】
可動部材７は、前後方向を長手方向とするアームレスト部７１と、該アームレスト部７１の後端部から略直角に突出する背凭れ部７２（５）からなる略Ｌ字状をしたものである。このアームレスト部７１は、支持腕４の上端部に設けた筒状の受部材７０内に長手方向廻りに回動自在となるように挿入されている。図１１（ａ）に、図９（ａ）の状態における受部材７０内でのアームレスト部７１の状態図を示し、図１１（ｂ）に、図９（ｂ）の状態における受部材７０内でのアームレスト部７１の状態図を示す。アームレスト部７１には突起７３が形成してあり、受部材７０内の空所７０ａ内を突起７３が移動するようになっており、前記空所７０ａの端壁にて突起７３の移動を規制させることで、可動部材７の動きが図９（ａ）から図９（ｂ）の間の範囲内に限定される。
【００３５】
背凭れ部７２の動作について説明する。使用者は、可動部材７を回動して図９（ｂ）に示す不使用状態にし、便蓋２を起立させる。そして、可動部材７を回動して図９（ａ）に示す使用状態にして、便座１に着座すると共に背凭れ部５に凭れるものである。
【００３６】
以上のような構成によれば、背凭れ部７２を設けてあっても便蓋２を背凭れ部７２と干渉することなく移動（起立、傾動）させることができる。また、背凭れ部５を取付プレート９を介して便器３に取り付けるものであるため、トイレルームの壁を補強したりする必要がないと共に後付けでも容易に背凭れ部５を設けることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a toilet seat backrest structure provided with a toilet seat and a toilet lid.
[0002]
[Prior art]
In recent years, in order to relax in a toilet room or to reduce the burden on the body of the elderly and the physically handicapped, a toilet having a toilet seat (a so-called Western toilet) provided with a backrest portion, an armrest, and the like has been used. . In order to provide a backrest on such a toilet, the back cover is removed and a backrest is attached instead (for example, see Patent Document 1). In other words, in such a toilet, the toilet lid is tilted forward when the toilet is not used and placed on the toilet (on the toilet seat), and when used while sitting on the toilet, the toilet lid is raised rearward. The toilet lid is positioned behind the backrest so that the seated user can lean against the backrest. Therefore, the toilet lid interferes with the backrest when rotating the toilet lid, and In order to provide the reclining portion, it was necessary to remove the toilet lid.
[0003]
However, if the toilet lid is not provided, the inside of the toilet bowl is always visible and the appearance is bad, dust accumulates on the upper surface of the toilet bowl, and if the toilet seat is provided with a heater, wasteful heat is radiated from the toilet seat. It was unpleasant. In view of this, there has been proposed a device in which the backrest is made movable to avoid interference with the toilet lid (for example, see Patent Document 2).
[0004]
In this apparatus, a supporting member is attached to a wall of a toilet room, and a backrest portion is rotatably provided on the supporting member, and the backrest portion is moved so as not to interfere with the toilet lid when the toilet lid is rotated. It is positioned above the turning locus of the lid, and the backrest is arranged at a predetermined position after passing through the toilet lid.
[0005]
However, in this case, the backrest is positioned above when the toilet lid is passed, and the backrest is placed at a predetermined position after passing the toilet lid. In the case where the backrest is moved with one hand, or when the operation is performed with one hand, it is necessary to move the backrest after moving the toilet lid, which is troublesome.
[0006]
In addition, since the support member for supporting the backrest is attached to the wall of the toilet room, it is necessary to reinforce the wall, and it is difficult and expensive to provide the backrest later.
