【産業上の利用分野】
この発明は、便座又は便蓋に使用される回転ダンパに関し、特に、該便座等が倒れてこないように起立させるための自立機能付き回転ダンパに関するものである。
【０００２】
【従来の技術】
図３に示すように便座（１）等に使用されている自立機能付き回転ダンパ（２）としては、図４〜図６に概略的に示したのが知られている。
【０００３】
同図において、（３）はダンパ外枠であり、（４）はダンパ軸である。該ダンパ軸（４）には径大のフランジ（５）が形成されており、該フランジ（５）には、一対の溝（６，６）が形成され、該一対の溝（６，６）は周方向において相対向する位置に形成されている。
【０００４】
（７，７）は一対の圧縮コイルスプリングであり、（８，８）は一対のボール、（９，９）は一対のボルト、（１０）はキャップである。前記ダンパ軸（４）のキャップ（１０）側の軸部は、前記便座（１）等の軸に連結される。
【０００５】
図４において、矢印で示すようにダンパ軸（４）を反時計回転方向に回転すると、すなわち、前記便座（１）を上方に開くと、図５に示すように一定角度のダンパ軸（４）の回転によりボール（８，８）が前記溝（６，６）内に嵌まり、便座（１）は一定角度（例えば、９０度）において自立（起立）する。
【０００６】
そして、便座（１）を閉めるとき、すなわち、前記ダンパ軸（４）を逆回転である図中時計回転方向に回転させようとするとき、前記ボール（８，８）は前記溝（６，６）を乗り越える必要があり、一定の荷重を加える必要がある。このとき、前記ボール（８，８）は、前記ボルト（９，９）で圧縮されている圧縮コイルスプリング（７，７）の弾発力が加えられており、何度も便座（１）の開け閉めを行なうと、図６の（ｂ）に示すように溝（６，６）の角部（１１）が摩耗し、自立力が低下してしまうという問題点があった。
【０００７】
【発明が解決しようとする課題】
本発明は上記点に着目してなされたものであって、回転の方向により自立力が異なり、かつ摩耗が少なく、スムーズに回転作業が行なえるようにした自立機能付き回転ダンパを提供することを目的とするものである。
【０００８】
【課題を解決するための手段】
上記課題を達成するため本発明は、ダンパ軸（１４）と、該ダンパ軸（１４）の外周に嵌入し該ダンパ軸（１４）と一体的に回転する自立カラー（２４）と、該自立カラー（２４）が回転できるようにその外周に嵌入される自立キャップ（３２）とからなり、
前記自立カラー（２４）は、周方向の相対向する位置に軸方向に沿った自立突起（３０，３０）を備え、
前記自立キャップ（３２）は、周方向の相対向する位置に設けられた一対の係止片（３６，３６）を備え、
前記係止片（３６，３６）は、溝（３４，３４）を設けることによって弾性を有し、かつ、内側に突出して前記自立突起（３０，３０）と係合する突部（３８）を備える自立機能付き回転ダンパ、或いは、
ダンパ軸（１４）と、該ダンパ軸（１４）の外周に嵌入し該ダンパ軸（１４）と一体的に回転する自立カラー（２４）と、該自立カラー（２４）が回転できるようにその外周に嵌入される自立キャップ（３２）とからなり、
前記自立キャップ（３２）は、周方向の相対向する位置に軸方向に沿った自立突起（３０，３０）を備え
前記自立カラー（２４）は、周方向の相対向する位置に設けられた一対の係止片（３６，３６）を備え、
前記係止片（３６，３６）は、溝（３４，３４）を設けることによって弾性を有し、かつ、内側に突出して前記自立突起（３０，３０）と係合する突部（３８）を備える自立機能付き回転ダンパとした。
【０００９】
前記自立カラー（２４）又は自立キャップ（３２）に形成した自立突起（３０，３０）としては、自立カラー（２４）又は自立キャップ（３２）と一体的に形成するようにしてもよく、また、金属性のニードルを自立カラー（２４）又は自立キャップ（３２）に埋設することにより自立突起としてもよい。自立突起の摩耗がより少なくて済むので、金属性のニードルを埋設したものを用いるほうが好ましい。
【００１０】
また、前記自立突起（３０，３０）としては、周方向の一方側の徐々に傾斜する傾斜部（３０ｂ）と、他方側の段部（３０ａ）とを形成することにより、便座を上げるときは、スムーズに行なえるので好ましい。
【００１１】
【作用】
図２において、便座を持ち上げて開けるとき、便座軸（２０）は矢印（Ａ）で示すように左回転（反時計方向に回転）をし、ダンパ軸（１４）の回転により、自立カラー（２４）も同様に矢印（Ａ）方向に回転する。
【００１２】
矢印（Ａ）方向に回転を続けると、自立カラー（２４）の自立突起（３０，３０）の傾斜部（３０ｂ）は自立キャップ（３２）の係止片（３６）に形成されている突部（３８，３８）の位置に至り、さらに回転させると、該係止片（３６）は突部（３８，３８）を介して傾斜部（３０ｂ）により徐々に外方に変形され、自立突起（３０，３０）が突部（３８，３８）の頂部を乗り越えると、図２に示すように自立突起（３０，３０）の段部（３０ａ）側に突部（３８，３８）が位置し、自立突起（３０，３０）と係止片（３６）の突部（３８，３８）が係合するような状態となり、ダンパ軸（１４）の逆回転（矢印Ｂ方向）を阻止し、便座の自立状態を保つ。
【００１３】
この便座の自立状態から、該便座を下ろす方向（矢印Ｂ方向）に回転しようとすると、前記自立突起（３０，３０）の段部（３０ａ）と係止片（３６）の突部（３８，３８）とが係止する状態となるが、さらに大きい荷重を与えることにより、自立突起（３０，３０）は係止片（３６）の弾性に抗してその突部（３８，３８）を乗り越えて、便座を下ろすことができる。
【００１４】
【実施例】
以下、本発明を図面に示す一実施例に基づき詳細に説明する。
図１および図２は、本発明に係る自立機能付きの回転ダンパ（１０）であり、図１はその概略的分解図で、図２はその要部断面図である。
【００１５】
（１２）はダンパ本体、（１４）はダンパ軸である。ダンパ本体（１２）から外に突出する該ダンパ軸（１４）の両側面には、平坦部（１６，１６）が形成されており、また、該ダンパ軸（１４）の突出部分はパイプ状の中空部（１８）となっている。
【００１６】
前記ダンパ軸（１４）の中空部（１８）内には、被回転部材である、例えば、便座軸（２０）が嵌入され、該便座を回転させることによりダンパ軸（１４）が回転するようになっている。すなわち、便座軸（２０）とダンパ軸（１４）とが空回りしないよう、該便座軸（２０）にもダンパ軸（１４）の平坦部（１６，１６）に対応するよう平坦部（２２）が形成されている。
【００１７】
（２４）は自立カラーであって、両側に平坦部（２６，２６）を有する中空体であり、前記ダンパ軸（１４）の外側に圧入される。
【００１８】
前記自立カラー（２４）の円弧部（２８，２８）の周方向における相対向する位置には、軸方向に沿って延びる自立突起（３０，３０）が形成されている。該自立突起（３０，３０）は、周方向の一方側の落込み段部（３０ａ）と、他方側における外周面より徐々に傾斜する傾斜部（３０ｂ）とを有している。
【００１９】
（３２）は自立キャップであって、筒形状をしており、合成樹脂材により形成されている。該自立キャップ（３２）には、周方向の相対向する位置に切込み溝（３４，３４）を形成することにより弾性を備えるようにした一対の係止片（３６，３６）が設けられている（図２参照）。
【００２０】
軸方向の溝（３４，３４）に沿った係止片（３６，３６）部分には、自立キャップ（３２）の内面方向に突出し、前記自立カラー（２４）の自立突起（３０，３０）と係合する突部（３８，３８）が形成されている。
【００２１】
前記自立キャップ（３２）は、前記ダンパ本体（１２）に対してネジ等で固定取付けされる。
【００２２】
前記実施例においては、自立突起（３０，３０）を自立カラー（２４）と一体的に形成した例を示しているが、自立カラー（２４）に、例えば、摩耗の少ない金属性のニードルを埋設することにより自立突起とするようにすれば、それだけ摩耗がなく、自立機能が低下することがないので、好ましい。
【００２３】
また、上記実施例においては、係止片（３６）を自立キャップ（３２）側に形成し、自立突起（３０，３０）を自立カラー（２４）側に形成した例を示しているが、この反対、すなわち、自立突起（３０，３０）を自立キャップ（３２）側に形成し、係止片（３６）を自立カラー（２４）側に形成するようにしてもよいことは勿論のことである。
【００２４】
次に、図２に基づいて本発明の自立ダンパの動作について説明する。
【００２５】
便座を持ち上げて開けるとき、便座軸（２０）は矢印（Ａ）で示すように左回転（反時計方向に回転）をし、該便座軸（２０）の回転により、ダンパ軸（１４）は矢印（Ａ）方向に回転する。このダンパ軸（１４）の回転により、自立カラー（２４）は該ダンパ軸（１４）に圧入されているので、該自立カラー（２４）も同様に矢印（Ａ）方向に回転する。
【００２６】
矢印（Ａ）方向に回転を続けると、自立カラー（２４）の自立突起（３０，３０）の傾斜部（３０ｂ）は自立キャップ（３２）の係止片（３６）に形成されている突部（３８，３８）の位置に至り、さらに回転させると、該係止片（３６）は突部（３８，３８）を介して傾斜部（３０ｂ）により徐々に外方に変形され、自立突起（３０，３０）が突部（３８，３８）の頂部を乗り越えると、図２に示すように自立突起（３０，３０）の段部（３０ａ）側に突部（３８，３８）が位置し、自立突起（３０，３０）と係止片（３６）の突部（３８，３８）が係合するような状態となり、ダンパ軸（１４）の逆回転（矢印Ｂ方向）を阻止し、便座の自立状態を保つ。
【００２７】
この便座の自立状態から、該便座を閉じる、すなわち下ろす方向（矢印Ｂ方向）に回転しようとすると、前記自立突起（３０，３０）の段部（３０ａ）と係止片（３６）の突部（３８，３８）とが係止する状態となるが、さらに大きい荷重を与えることにより、自立突起（３０，３０）は係止片（３６）の弾性に抗して突部（３８，３８）を乗り越えて、便座を閉じる（下ろす）ことができる。
【００２８】
このように、便座を上げるときは、傾斜部（３０ｂ）によりスムーズに便座を立上げること（自立）ができ、また、便座が自立した状態を段部（３０ａ）と突部（３８）との係止により保持でき、便座を下ろすときは、便座を上げるときよりも抵抗を大きくすることにより、便座の上げ下ろし作業が円滑に行なえる。
【００２９】
【発明の効果】
以上説明したように本発明によれば、自立機能を果たす機構において、突部を有し弾性を利用した係止片と、該係止片と係止する自立突起をダンパ軸と共動する自立カラーに形成するようにし、該自立突起の一側に傾斜部、他側に段部を形成するようにしたので、便座を上げるときは軽い力で、また、下ろすときは重い力で行なえ、便座の上げ下ろしが円滑に行なえる。
【００３０】
また、自立突起と係止片の突部との係脱において、係止片は弾性を利用しているので、何度使用してもその自立突起と突部とが摩耗し自立機能が低下するということがない。
【００３１】
さらに、従来の自立機能付き回転ダンパに比して、部品点数が少なくて済み、組立て作業が簡単となり、かつ製造コストも安価なものとなる。

When the rotation is continued in the direction of the arrow (A), the inclined portions (30b) of the self-standing projections (30, 30) of the self-standing collar (24) become the protrusions formed on the locking pieces (36) of the self-standing cap (32). When the locking piece (36) reaches the position (38, 38) and is further rotated, the locking piece (36) is gradually deformed outward by the inclined portion (30b) via the projection (38, 38), and the self-standing projection ( When the projections (30, 30) get over the tops of the projections (38, 38), the projections (38, 38) are located on the step (30a) side of the self-standing projections (30, 30) as shown in FIG. The self-standing projections (30, 30) and the projections (38, 38) of the locking pieces (36) are engaged with each other, so that the reverse rotation (in the direction of arrow B) of the damper shaft (14) is prevented, and Stay independent.
[0027]
From the self-standing state of the toilet seat, when the toilet seat is to be closed, that is, to be rotated in the lowering direction (arrow B direction), the step (30a) of the self-standing projection (30, 30) and the projection of the locking piece (36). (38, 38) are locked, but by applying a larger load, the self-standing projections (30, 30) project against the elasticity of the locking pieces (36). overcame, close the toilet seat (down) can be.
[0028]
As described above, when raising the toilet seat, the inclined seat (30b) allows the toilet seat to be smoothly raised (self-standing), and the state in which the toilet seat is self-standing is defined by the step (30a) and the projection (38). It can be held by locking, and when lowering the toilet seat, the resistance is greater than when raising the toilet seat, so that the operation of raising and lowering the toilet seat can be performed smoothly.
[0029]
【The invention's effect】
As described above, according to the present invention, in a mechanism that achieves a self-supporting function, a self-standing member that has a projection and uses elasticity and a self-standing protrusion that engages with the locking member cooperates with a damper shaft. The self-standing projection is formed with an inclined portion and a step portion on the other side, so that the toilet seat can be raised with a light force when it is raised and a heavy force when it is lowered. Can be lifted and lowered smoothly.
[0030]
Further, in the engagement and disengagement between the self-supporting projection and the projection of the locking piece, the locking piece uses elasticity, so that the self-supporting projection and the projection are worn and the self-supporting function is deteriorated even if used many times. There is no such thing.
[0031]
Furthermore, as compared with the conventional rotary damper with a self-supporting function, the number of parts is reduced, the assembling work is simplified, and the manufacturing cost is reduced.
