Description

【０００１】
【発明の属する技術分野】
本発明は便器装置に関し、特に便器上に載置固定される本体カバーに回動自在に枢支される便蓋を着脱可能とした便器装置に関するものである。
【０００２】
【従来の技術】
便器装置において、便器上に載置固定される本体カバーに便座と便蓋が回動自在に枢支したものが従来から知られているが、通常その便蓋は簡単に着脱できるようにはなっていない。しかし、便器装置を清掃する際に便蓋が取り外せないと清掃し難い部分が生じ、隅々まで衛生的に保つのに大変な手間を要するという問題があった。
【０００３】
そこで、例えば特開平７−３１５６２号公報に開示されているように、便蓋を着脱可能に構成したものが提案されている。その便蓋着脱装置は、便蓋を回動自在に枢支する両側の枢支部に、回動中心部から外周面に延びて一端開放された軸孔を形成した軸受部を設け、この軸受部に軸孔の外部との連通を遮断する位置と開放する位置との間で回動操作可能な着脱用部材を設けて構成されている。一方、本体カバーの両側部には便蓋の閉止速度抑制装置がその制動軸を両側外方に突出させて配設され、制動軸の先端部を便蓋の軸受部の軸孔に嵌入係合させるように構成されている。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記便蓋着脱装置では、その軸受部の軸孔が一端開放されており、その軸孔に制動軸の軸端が係合しているので、便蓋の開閉の度に軸孔の両側面に大きな力が作用し、そのため軸孔の剛性・強度を極めて高くしないと便蓋を繰り返し開閉する間に軸孔が容易に変形・損傷する恐れがあり、長期にわたって安定して閉止速度抑制機能及び軸受機能を保持することができないという問題がある。また、便蓋を装着する際に着脱用部材を操作して軸孔を開き、制動軸を軸孔に挿入した後着脱用部材を操作して軸孔の外部との連通を遮断する操作が必要であるため、操作が面倒であるとともに着脱用部材を操作して軸孔を遮断するのを忘れた場合や着脱用部材の係止が不十分で不測に移動した場合には便蓋が脱落する恐れがあるという問題がある。
【０００５】
本発明は、上記従来の問題点に鑑み、長期にわたって安定した閉止速度抑制機能及び軸受機能を保持しながら便蓋の着脱が可能でかつ着脱操作の簡単な便器装置を提供することを目的としている。
【０００６】
【課題を解決するための手段】
本発明の便器装置は、便座と便蓋を回動自在に枢支する本体カバーを便器上に載置固定してなる便器装置において、本体カバーの互いに略平行な一対の側面に同一水平軸芯上に位置させて便蓋を枢支する一対の軸を突出し、一方の軸は便蓋の閉止速度抑制装置の制動軸にて構成し、他方の軸は本体カバーと一体の固定軸にて構成し、便蓋の基端部の一側に制動軸をその一端から嵌入係合させる係合軸受穴を有する支持軸受部を設け、便蓋の基端部の他側に固定軸をその周側面から挿入・抜き出し可能で挿入状態で固定軸を回転自在に保持する着脱軸受部を設けたものであり、便蓋の一側の支持軸受部に制動軸の嵌入係合させた後他側の着脱軸受部にその周側面から固定軸を挿入して保持することにより便蓋を装着し、また逆の工程で取り外すことができるので簡単に便蓋を着脱することができ、かつ制動軸を切欠部のない係合軸受穴に一端から嵌入係合させるので支持軸受部の剛性・強度が高く、長期にわたって安定した閉止速度抑制機能及び軸受機能を保持することができる。
【０００７】
また、着脱軸受部が、便蓋に設けられ周側に固定軸の挿入開口を有する軸受ハウジング部と、軸受ハウジング部内に回動自在に収納保持され周壁に固定軸の受入開口を有する可動軸受部材と、可動軸受部材をその受入開口を挿入開口と重ならない位置に向けて付勢する弾性体と、可動軸受部材の抜け出しを防止する軸受蓋とを備えると、可動軸受部材を弾性体の付勢力に抗して操作し、挿入開口と受入開口を一致させた状態で固定軸を挿脱すると、弾性体の付勢力にて自動的に可動軸受部材が受入開口を挿入開口と重ならない位置に向けて回動されるので、操作が簡単でかつ不測に固定軸が着脱軸受部から抜け出して便蓋が外れてしまう恐れもない。
【０００８】
また、本体カバーに互いに対向する一対の側面を形成する凹部を形成し、便蓋の基端部両側にこれら一対の側面の内側に各々対向するように支持軸受部と着脱軸受部を設けると、凹部両側の本体カバーの両側部の内側に便蓋両側の支持軸受部と着脱軸受部が位置しているので、各軸受部が本体カバーの外側に露出せず、すっきりした外観を得ることができ、また本体カバーの両側部の一方に閉止速度抑制装置を配置することができる。
【０００９】
また、着脱軸受部において、可動軸受部材の端壁外面に回動軸芯から偏芯した位置に操作つまみを突設し、軸受ハウジング部に操作つまみが貫通する円弧状の長孔を形成すると、着脱軸受部の軸受ハウジング部の内側面に操作つまみが突出しているので、便蓋を開いた状態で容易に操作つまみを操作して挿入開口と受入開口を一致させて固定軸を挿脱することができ、操作性良く便蓋を着脱することができ、しかも操作つまみが外面に露出せず、見栄えがよい。
【００１０】
また、可動軸受部材の端壁外面の軸芯部に軸受ハウジング部の内側面に形成した中心穴に嵌合する円形突起を設けるとともにその直径方向に係合溝を設け、軸受ハウジング部に一端を固定して配置した渦巻きばねの中心側の他端部を係合溝に係合させると、軸受ハウジング部の内側面に渦巻きばねを配置した後可動軸受部材を挿入して係合溝に渦巻きばねの他端部を係合させることによって簡単に組み付けることができるとともにばねの作用に無理がなく安定した動作を確保できる。
【００１１】
【発明の実施の形態】
以下、本発明の便器装置の一実施形態について、図１〜図８を参照して説明する。
【００１２】
図１において、１は便器（図示せず）上に載置固定される本体カバーで、便座（図示せず）と便蓋２が回動自在に枢支される。本体カバー１の後部には、後端部と両側部を除いて中央部に凹部３が形成され、この凹部３両側に互いに対向する略平行な一対の内側面４ａ、４ｂが形成されている。これら内側面４ａ、４ｂには同一水平軸芯上に位置させて便蓋２の閉止速度を抑制する制動軸５と、本体カバー１と一体の固定軸６が突設されている。
【００１３】
制動軸５は、図３に示すように、本体カバー１の一側部１ａ内に配置されたオイルダンパーから成る閉止速度抑制装置７の異径断面の出力軸にて構成され、内側面４ａを貫通して凹部３に向けて突出されている。閉止速度抑制装置７はその外周を保持する取付ブラケット８にて本体カバー１に取付けられるとともに、出力軸とは反対側に突出された回り止め片７ａが取付ブラケット８の係合部８ａに係合されて回転モーメントを支持するように構成されている。
【００１４】
便蓋２の基端部の一側には、図１〜図３に示すように、制動軸５をその一端から嵌入係合させる異径断面の係合軸受穴１０を有する支持軸受部９が設けられている。支持軸受部９は、係合軸受穴１０を形成した軸受部材１１を便蓋２に形成された軸受ハウジング部１２内に嵌着し、ボルト１３にて締結固定して構成されている。
【００１５】
便蓋２の基端部の他側には、図１、図２及び図４〜図８に示すように、固定軸６をその周側面から挿入・抜き出し可能で挿入状態で固定軸６を回転自在に保持する着脱軸受部１４が設けられている。着脱軸受部１４は、便蓋２に形成された軸受ハウジング部１５と、その内部に回動自在に収納保持された可動軸受部材１６と、可動軸受部材１６を所定位置に常時位置するように回動付勢する渦巻きばね１７と、軸受ハウジング部１５の外側面の開口を閉じて可動軸受部材１６の抜け出しを防止する軸受蓋１８と、軸受蓋１８を軸受ハウジング部１５に締結固定するボルト１９にて構成されている。
【００１６】
軸受ハウジング部１５の周壁には固定軸６を挿通可能な挿入開口２０が形成され、可動軸受部材１６の周壁にも固定軸６を内部に挿入可能な受入開口２１が形成されており、可動軸受部材１６は渦巻きばね１７にてその受入開口２１が挿入開口２０と重ならない位置に常時位置するように付勢されている。可動軸受部材１６の端壁１６ａ外面には回動軸芯から偏芯した位置にこの可動軸受部材１６を回動操作する操作つまみ２２が突設され、軸受ハウジング部１５の端壁１５ａにこの操作つまみ２２が貫通する円弧状の長孔２３が形成されている。
【００１７】
軸受ハウジング部１５の端壁１５ａの一端部には、図５に示すように、その内部に突出するように軸受蓋１８の取付ボス２４が突設され、その中心にボルト１９を螺合させる雌ねじ２４ａが形成されている。渦巻きばね１７の固定側の一端部１７ａは、この取付ボス２４の周囲に略半周程度巻回され、その先端が軸受ハウジング部１５の周壁に係合されるとともに他端側の取付ボス２４の近傍位置が端壁１５ａから突設されたばね受け突起２５に係合されて渦巻きばね１７が固定されている。可動軸受部材１６の端壁１６ａの外面の軸芯部には、図４、図６に示すように、軸受ハウジング部１５の端壁１５ａ内面に形成された中心穴２６に嵌合する円形突起２７が突設され、かつこの円形突起２７に渦巻きばね１７の中心側の他端部１７ｂが係合する直径方向の係合溝２８が形成されている。
【００１８】
軸受蓋１８には、図７に示すように、固定軸６が相対回転可能に貫通する軸貫通穴２９とこの軸貫通穴２９に固定軸６を挿入する挿入開口３０が形成され、一端部の取付ボス部１８ａにはボルト１９を挿通してその頭部が係合するボルト穴３１が形成されている。また、軸受蓋１８には、挿入開口３０を除いて軸貫通穴２９を取り囲むように、外周面が軸受ハウジング部１５の周壁内周に嵌合し、内周面に可動軸受部材１６の周壁外周面が回動自在に嵌合する軸受支持筒部３２が設けられている。
【００１９】
以上の構成において、便蓋２を装着する際には、まず一側の支持軸受部９の係合軸受穴１０に制動軸５を嵌入係合させる。次に、他側の着脱軸受部１４において、図８の（ａ）から（ｂ）の如く、操作つまみ２２を長孔２３に沿って渦巻きばね１７の付勢力に抗して移動操作して可動軸受部材１６の受入開口２１を軸受ハウジング部１５の挿入開口２０及び軸受蓋１８の挿入開口３０に合わせ、これら挿入開口２０、３０及び受入開口２１を通して可動軸受部材１６内に固定軸６を挿入した後、操作つまみ２２を解放すると渦巻きばね１７の付勢力にて可動軸受部材１６が再び図８（ａ）に示すように復帰回動して挿入開口２０、３０が閉じられ、固定軸６は可動軸受部材１６内で相対回転自在に保持される。こうして、便蓋２が開閉回動自在に装着される。
【００２０】
また、便蓋２を取り外す際には、着脱軸受部１４における操作つまみ２２を操作して可動軸受部材１６を回動させ、受入開口２１を挿入開口２０、３０に合わせて固定軸６をこれら受入開口２１と挿入開口２０、３０を通して着脱軸受部１４から抜き出した後、係合軸受穴１０から制動軸５を引き抜くように抜き出すことによって簡単に便蓋２を取り外すことができる。
【００２１】
このように便蓋２を開いた状態で操作つまみ２２を操作して挿入開口２０、３０と受入開口２１を一致させることにより容易に固定軸６を挿脱して操作性良く便蓋２を着脱することができ、簡単な操作で便蓋２を着脱することができる。特に、可動軸受部材１６を渦巻きばね１７の付勢力に抗して操作して固定軸６を挿脱すると、渦巻きばね１７の付勢力にて自動的に可動軸受部材１６が受入開口２１を挿入開口２０、３０と重ならない位置に向けて回動されるので、操作が簡単でかつ不測に固定軸６が着脱軸受部１４から抜け出して便蓋２が外れてしまう恐れもない。
【００２２】
また、着脱軸受部１４は、軸受ハウジング部１５の内側面に渦巻きばね１７を配置した後可動軸受部材１６を挿入して係合溝２８に渦巻きばね１７の他端部１７ｂを係合させ、軸受蓋１８をボルト１９にて締結固定することによって簡単に組み付けることができ、しかも渦巻きばね１７を用いたことにより可動軸受部材１６の回動付勢作用に無理がなく安定した動作を確保できる。
【００２３】
また、便蓋２の装着状態では制動軸５が支持軸受部９の切欠部のない係合軸受穴１０に嵌入係合されているので、支持軸受部９の剛性・強度が高く、長期にわたって安定した閉止速度抑制機能及び軸受機能を保持することができる。また、本体カバー１の凹部３両側の両側部１ａ、１ｂの内側に便蓋２両側の支持軸受部９と着脱軸受部１４が位置しているので、各軸受部９、１４が本体カバー１の外側に露出せず、また操作つまみ２２が外面に露出せず、すっきりした外観を得ることができて見栄えがよい。また、さらに可動軸受部材１６の操作つまみ２２の定常位置を便蓋２の装着状態でかつ便座を自立させても緩衝しない位置関係に配置しており、便座の開閉により不用意に操作つまみ２２が回転して便蓋２が外れることはない。
【００２４】
【発明の効果】
本発明の便器装置によれば、以上の説明から明らかなように、便蓋の一側の支持軸受部に制動軸の嵌入係合させた後他側の着脱軸受部にその周側面から固定軸を挿入して保持することにより便蓋を装着し、また逆の工程で取り外すことができるので簡単に便蓋を着脱することができ、しかも制動軸を切欠部のない係合軸受穴に一端から嵌入係合させるので支持軸受部の剛性・強度が高く、長期にわたって安定した閉止速度抑制機能及び軸受機能を保持することができる。
【００２５】
また、着脱軸受部を、周側に固定軸の挿入開口を有する軸受ハウジング部内に、周壁に固定軸の受入開口を有する可動軸受部材を回動自在に収納保持した構成とし、弾性体にて自動的に可動軸受部材が受入開口を挿入開口と重ならない位置に向けて回動させるようにすると、操作が簡単でかつ不測に固定軸が着脱軸受部から抜け出して便蓋が外れてしまう恐れもない。
【００２６】
また、本体カバーに互いに対向する一対の側面を形成する凹部を形成し、便蓋の両側部にこれら一対の側面の内側に各々対向するように支持軸受部と着脱軸受部を設けると、各軸受部が本体カバーの外側に露出せず、すっきりした外観を得ることができ、また本体カバーの両側部の一方に閉止速度抑制装置を配置することができる。
【００２７】
また、着脱軸受部において、可動軸受部材の端壁外面に軸受ハウジング部の円弧状の長孔を貫通する操作つまみを突設すると、操作つまみが軸受ハウジング部の内側面に突出しているので、便蓋を開いた状態で容易に操作つまみを操作して挿入開口と受入開口を一致させて固定軸を挿脱することができ、操作性良く便蓋を着脱することができ、しかも操作つまみが外面に露出せず、見栄えがよい。
【００２８】
また、可動軸受部材の端壁外面の軸芯部に軸受ハウジング部の内側面に形成した中心穴に嵌合する円形突起を設けるとともにその直径方向に係合溝を設け、軸受ハウジング部に一端を固定して配置した渦巻きばねの他端部を係合溝に係合させると、軸受ハウジング部の内側面に渦巻きばねを配置した後可動軸受部材を挿入して係合溝に渦巻きばねの他端部を係合させることによって簡単に組み付けることができるとともにばねの作用に無理がなく安定した動作を確保できる。

A bolt hole 31 through which the bolt 19 is inserted and engaged with the head is formed in the mounting boss portion 18a. The bearing lid 18 has an outer peripheral surface fitted to the inner peripheral surface of the bearing housing portion 15 so as to surround the shaft through hole 29 except for the insertion opening 30, and the outer peripheral surface of the movable bearing member 16 is connected to the inner peripheral surface. A bearing support cylinder portion 32 is provided in which the surface is rotatably fitted.
[0019]
In the above configuration, when the toilet lid 2 is mounted, the brake shaft 5 is first fitted into the engagement bearing hole 10 of the support bearing portion 9 on one side. Next, in the detachable bearing portion 14 on the other side, as shown in FIGS. 8A to 8B, the operation knob 22 is moved along the long hole 23 against the urging force of the spiral spring 17 to be movable. The receiving opening 21 of the bearing member 16 is aligned with the insertion opening 20 of the bearing housing portion 15 and the insertion opening 30 of the bearing lid 18, and the fixed shaft 6 is inserted into the movable bearing member 16 through the insertion openings 20, 30 and the receiving opening 21. After that, when the operation knob 22 is released, the movable bearing member 16 is returned and rotated again by the urging force of the spiral spring 17 as shown in FIG. 8A, the insertion openings 20 and 30 are closed, and the fixed shaft 6 is movable. The bearing member 16 is held so as to be relatively rotatable. In this way, the toilet lid 2 is mounted so as to be freely opened and closed.
[0020]
Further, when the toilet lid 2 is removed, the movable bearing member 16 is rotated by operating the operation knob 22 in the detachable bearing portion 14, and the fixed shaft 6 is received by aligning the receiving opening 21 with the insertion openings 20 and 30. The toilet lid 2 can be easily removed by extracting the brake shaft 5 from the engagement bearing hole 10 after extracting from the detachable bearing portion 14 through the opening 21 and the insertion openings 20 and 30.
[0021]
In this way, the operation knob 22 is operated with the toilet lid 2 opened to make the insertion openings 20 and 30 and the receiving opening 21 coincide with each other so that the fixed shaft 6 can be easily inserted and removed, and the toilet lid 2 is attached and detached with good operability. The toilet lid 2 can be attached and detached with a simple operation. In particular, when the movable bearing member 16 is operated against the biasing force of the spiral spring 17 and the fixed shaft 6 is inserted and removed, the movable bearing member 16 automatically inserts the receiving opening 21 by the biasing force of the spiral spring 17. Since it is rotated toward a position where it does not overlap with 20, 30, there is no possibility that the fixed shaft 6 will come out of the detachable bearing portion 14 and the toilet lid 2 will come off unintentionally.
[0022]
The detachable bearing portion 14 also includes a spiral spring 17 disposed on the inner surface of the bearing housing portion 15, and then the movable bearing member 16 is inserted to engage the other end portion 17 b of the spiral spring 17 in the engagement groove 28. The lid 18 can be easily assembled by fastening and fixing it with the bolts 19, and the use of the spiral spring 17 makes it possible to ensure a stable operation without unreasonable rotational biasing action of the movable bearing member 16.
[0023]
In addition, when the toilet lid 2 is mounted, the brake shaft 5 is fitted and engaged in the engagement bearing hole 10 without the notch portion of the support bearing portion 9, so that the rigidity and strength of the support bearing portion 9 is high and stable over a long period of time. Thus, it is possible to maintain the closed speed suppressing function and the bearing function. In addition, since the support bearing portions 9 and the detachable bearing portions 14 on both sides of the toilet lid 2 are located inside the both side portions 1 a and 1 b on both sides of the concave portion 3 of the main body cover 1, the bearing portions 9 and 14 are attached to the main body cover 1. It is not exposed to the outside, and the operation knob 22 is not exposed to the outer surface, and a clean appearance can be obtained. Further, the steady position of the operation knob 22 of the movable bearing member 16 is arranged in a positional relationship in which the toilet lid 2 is attached and the toilet seat is not buffered even when the toilet seat is self-supported. The toilet lid 2 does not come off due to rotation.
