Abstract

【課題】動作の精確度をアップさせ、部品全体の組立が簡単なプッシュ・スイッチ連動構造の提供。
【解決手段】主にプッシュ・キー１と、スイッチ・ボックス２と、定位連動片３と、弾性接触片４とからなり、プッシュ・キーを押すことによりと、定位エレメント１４は連動されて同時に動き、定位エレメントと環状階段路及び定位連動片は相互に循環セッティング関係を形成する。そして定位連動片は弾性接触片を跳ね上げるように推し動かし、スイッチが通電する（ＯＮ）又は切断する（ＯＦＦ）状態を作る。電流が過負荷になると、弾性接触片が熱により変形し、反対方向に跳ね上がるため、弾性接触片の接触点はもう一方の接触点から離れ、電気回路を切断（ＯＦＦ）状態にする。それと同時に、定位エレメントは定位連動片のあけ孔３１内縁の制限を失い、スプリング１５により、プッシュ・キーを上に跳ね上げ、再び元の使用状態に戻ることになる。
【選択図】　　図１An object of the present invention is to provide a push-switch interlocking structure in which the accuracy of operation is improved and the assembly of all parts is easy.
A push key, a switch box, a localization interlocking piece, and a resilient contact piece are used. When a push key is pressed, a localization element moves in conjunction with the push key. , The localization element, the annular stairway, and the localization interlocking piece form a circular setting relationship with each other. Then, the localization interlocking piece pushes the elastic contact piece so as to jump up, so that the switch is energized (ON) or disconnected (OFF). When the current is overloaded, the elastic contact piece is deformed by heat and jumps up in the opposite direction, so that the contact point of the elastic contact piece is separated from the other contact point, and the electric circuit is cut (OFF). At the same time, the localization element loses the limit of the inner edge of the hole 31 of the localization interlocking piece, and the push key is jumped up by the spring 15 to return to the original use state.

Description

【０００１】
【考案の属する技術分野】本考案はプッシュ・スイッチ連動構造に関するものである。更に詳しくは、本考案は、プッシュ・スイッチを押すことにより、定位エレメントが同調して動作し、定位エレメントと環状階段路及び定位連動片が相互に連動して循環セッティング関係を形成し、特に定位連動片が弾性接触片に直接連動して跳ね上げ、スイッチが通電する（ＯＮ）或いは切断（ＯＦＦ）する状態を形成すると共に、そのほか、電流が過負荷になると、弾性接触片は熱によって変形して彎曲し、該弾性接触片の接点がもう一方の接点から離れ、スイッチ構造は電気回路が切断した（ＯＦＦ）状態となり、これと同時に該弾性接触片は直接定位連動片を推し動かして再び元の使用状態まで回すことができるプッシュ・スイッチ連動構造に関するものである。
【０００２】
【従来の技術】一般の電源スイッチの操作において、最も重要なの点は通電及び切断の二つの動作のプロセスにある。スイッチ内部の構成部品の連動動作を確実に且つ効率的に実行させ、スイッチ部品を簡略化して製造コストを低減するために、スイッチ構造の研究及び改良は製造者にとって重要な共同課題となる。
【０００３】
スイッチ構造の先行特許は、数多くあり、一例を挙げれば、アメリカ特許第４，１６７，７２０号、第４，９３７，５４８号、第５，２２３，８１３号、第５，４５１，７２９号、第５，５５８，２１１号などなど、枚挙にいとまがないほどである。しかしながら、これらの先行特許はすべて下記のような共通の欠点がある。
【０００４】
（１）連動する構成部品が多く、連動プロセスが複雑であるため、プッシュ・キーと末端部品の間の動作関係にズレが生じ、製造コストも高い。
（２）動作関係が不確実であるため、故障のケースが増え、使用上の安全性に欠ける。
（３）プッシュ・キーが直接または間接的に弾性接触片を圧迫して通電或いは切断を行うので、接触不良又は断裂を起こしやすく、通電品質を低下させ、使用寿命を短縮させる。
【０００５】
公知のアメリカ特許第５，２２３，８１３号に掲載されている構造のプッシュ・スイッチ連動構造は、図８、図９、図１０に示されている。図８、図９、図１０において、プッシュ・キー３３を押すと、先ずプッシュ・キー下方にある連動レバー３９が連動し、該連動レバーにより連接された上下にスライドする部品２７を通して、その下にある弾性接触片５を圧迫又は解放して、その上部接点７と接触させるか、又は下部接点１から離すことで、電気回路のオン又はオフを行うものである。これは、プッシュ・キーが間接的に連動して弾性接触片を圧迫又は解放する方法であり、理想的な状態のもとでは、操作及び使用上なんら問題もないが、しかし、構成部品が複雑であるため、製造コストが高く、操作による故障も増え、連動プロセスにおける反応の遅れ及び弾性接触片に潜在する断裂或いは弾性疲労など、依然として明らかな欠点が存在しており、メーカーとユーザーの共通課題となっていることから、更なる改良が待たれるところである。
【０００６】
【考案が解決しようとする課題】そこで、本考案者は、スイッチの構造に関わる構成部品が多く、また製造コストが高い。しかも連動操作上頻繁に故障が発生し、連動プロセスにおいて反応が遅い及び弾性接触片の断裂、弾性疲労といった諸問題を解決することができたものである。
【０００７】
本考案が解決しようとする課題は、構成部品相互に直接的に連接関係を持たせることにより、動作の精確度をアップさせ、誤操作を減少させる、定位エレメント、環状階段路、定位連動片及び弾性接触片からなる簡単なプッシュ・スイッチ連動構造を提供することにある。
【０００８】
【課題を解決するための手段】本考案は、主にプッシュ・キーと、スイッチ・ボックスと、定位連動片と、弾性接触片とからなるプッシュ・スイッチ連動構造である。該プッシュ・キーはスイッチ・ボックスの上に可動的にはめ込んで取り付けられ、プッシュ・キーとスイッチ・ボックスとの間には定位エレメントがセットされ、該定位エレメントの片端部には凸レバーが形成されている。また、プッシュ・キーとスイッチ・ボックス間の側面にはへこみ状に環状階段路が設けられ、該環状階段路の内部には斜状の凸部を設けている。該定位連動片にはあけ孔をつくり、環状階段路の開口部の近傍に組み合わさり、且つ環状階段路の開口に対して左右に振れることができる。該定位連動片には鉤部を設けており、該鉤部は弾性接触片の可動端に可動的に掛り、定位エレメントの凸レバー端は定位連動片のあけ孔を突き通して環状階段路の内部に挿入する。このように構成されたプッシュ・スイッチ連動構造により、動作の精確度をアップさせ、誤操作を減少させ、更に部品全体の組立を簡単にし、製造コストを低減するばかりでなく、本考案の付属効果として、スイッチ構造の使用寿命を延長し、ユーザーの出費を少なくすることができるという格別優れた効果を奏するものである。
【０００９】
本考案のプッシュ・スイッチ連動構造を実施する場合、プッシュ・キーを押すと、定位エレメントは連動されて同時に動き、定位エレメントと環状階段路及び定位連動片は相互に循環セッティング関係を形成する。そして定位連動片は弾性接触片を跳ね上げるように推し動かし、スイッチが通電する（ＯＮ）又は切断する（ＯＦＦ）状態を作る。電流が過負荷になると、弾性接触片が熱を受けて変形し、反対方向に彎曲して跳ね上がるため、弾性接触片の接触点はもう一方の接触点から離れ、電気回路を切断（ＯＦＦ）状態にする。それと同時に、弾性接触片の可動端は定位連動片を連動させて振らせ、環状階段路における斜状凸部の上端部に開口を形成する。定位エレメントは定位連動片のあけ孔内縁の制限を失い、プッシュ・キー内部のスプリングにより、プッシュ・キーを上に跳ね上げ、再び元の使用状態に戻ることになる。更に本考案の詳細は、以下の如くである。

【考案の実施の形態】本考案の課題、特徴及び効果を明らかにするために、下記に比較的良い実施例を図面に基づいて詳細に説明するが、以下の記載内容は、本考案の比較的良好な実施例を述べたものに過ぎず、本考案の実体の範囲を限定することはできない。本考案の請求項の範囲に基づく変更は、全て本考案の実用新案登録請求の範囲内に属するものとする。
【００１２】
図１は、本考案のプッシュ・スイッチ連動構造の立体分解図である。図２は、スイッチ・ボックスの斜視図である。図３は、スイッチ構造の断面図である。本発明のプッシュ・スイッチ連動構造は、主にプッシュ・キー１と、スイッチ・ボックス２と、定位連動片３、弾性接触片４を含んでいる。
【００１３】
図１乃至図３において、該プッシュ・キー１の上方にはカバー１０を組み合わせており、プッシュ・キー１の側面に少なくとも一つの締結鉤１１を突出させて設置している。該プッシュ・キー１はスイッチ・ボックス２上方の開口に可動的にはめ込んで取り付けられ、プッシュ・キー１とスイッチ・ボックス２との間に少なくとも一つの弾性エレメント１２、本実施例では圧縮ばねを組み合わせており、これによってプッシュ・キー１に外向き（上向き）の弾力を持たせている。プッシュ・キー１の側面には接合柱１３を設け、該接合柱１３は定位エレメント１４とセットされる。該定位エレメント１４の上端はリング１４１となり、定位エレメント１４の下端には凸レバー１４２が設けられ、該凸レバー１４２はスイッチ・ボックス２内の環状階段路２２方向に彎曲している。定位エレメント１４のリング１４１及びスプリング１５は接合柱１３にかぶさり、スプリング１５の弾力により定位エレメント１４のリング１４１の縁部を押し上げ、これによって定位エレメント１４はプッシュ・キー１の接合柱１３に取り付けられ、且つ定位エレメント１４はリング１４１を中心軸としてプッシュ・キー１に対し、振れることが可能となる。該スプリング１５は定位エレメント１４を環状階段路２２方向に向ける弾力を与える。本発明の実施例ではスプリングは圧縮ばねを使うこととする。
【００１４】
前記プッシュ・キー１とスイッチ・ボックス２との間にある弾性エレメント１２を収納するために、該スイッチ・ボックス２には少なくとも一つの凹型槽２７が設けられている。その内側壁面には少なくとも一つの締結槽２０がくぼんで設置され、また一つの横梁２１が設けられており、該締結槽２０及び横梁２１はプッシュ・キー１の向かい両サイドにある少なくとも一つの突起した締結鉤１１に対応している。また、スイッチ・ボックス２の内側壁面には多角状の環状階段路２２がくぼみに設置され、該環状階段路２２の中に斜状凸部２３を設け、該環状階段路２２の近傍に連接孔２４を設ける。スイッチ・ボックス２の底面には少なくとも二つの接触端子が装着され、本実施例では、接触端子は二つとし、それぞれ第１接触端子２５と、第２接触端子２６とする。第１接触端子２５の上方彎曲部には二つの凸柱２５１を設け、第２接触端子２６の上方には接点孔２６１があり、これと結合する第２接点２６２を設ける。
【００１５】
定位連動片３は一体的に成形されたプレートであり、その面上にあけ孔３１を設けている。該あけ孔３１はほぼ「く」字型の不規則な形状であり、あけ孔３１の右下端のへこみをＡ点とし、あけ孔３１の上端のへこみをＢ点とする。また、あけ孔３１の下には接合孔３２を設け、ボルト３０を使って該接合孔３２を貫通し、スイッチ・ボックス２の環状階段路２２の近傍にある連接孔２４に勘合ており、これによって定位連動片３は接合孔３２を中心軸としてスイッチ・ボックス２の環状階段路２２に対し、左右に振れることができるようになっている。定位連動片３は鉤部３３を有し、該鉤部３３の上方には突起部３３１を設け、鉤部３３と該突起部３３１との間に鉤溝３３２を形成させる。該鉤溝３３２は弾性接触片４の可動端を軽く挟み、これによって該弾性接触片４は定位連動片３と直接的な連動関係を生じさせる。
【００１６】
該弾性接触片４は一枚の成形されたプレートであり、その上に設けた接触点は弾性接触片体の両側に跳ねることができ、熱を受けた場合、変形して反対方向に彎曲して跳ねる。該弾性接触片４は複合金属薄片であり、熱を受けると片側に彎曲して変形する。本実施例では、弾性接触片４の両側には脚部４１をつくり、中央部に弾性チップ４２を設け、弾性接触片４の全体はほぼ「Ｅ」字型とする。該両側の脚部４１の開口端部分にそれぞれ穿孔４１０があり、二つの穿孔４１０間のピッチは前記第１接触端子２５の二つの凸柱２１５のピッチよりやや広めに設けられるため、両脚部４１を互いに近寄らせ、二つの穿孔４１０をそれぞれ第１接触端子２５上の二つの凸柱２５１にはめることができる。これによって弾性接触片４がやや円孤状になり、中央部の弾性チップ４２の自由端は弾性接触片４の円孤方向と反対に向くことになる。該弾性チップ４２の自由端には接点孔４２１があり、該接点孔４２１は下向きの第１接点４２２と組み合わせる。本実施例では、弾性接触片４は熱を受けると片側に彎曲変形する双合金プレートである。
【００１７】
組立時、定位エレメント１４の凸レバー１４２を定位連動片３のあけ孔３１を貫通させてスイッチ・ボックス２の環状階段路２２の中まで挿入する。
【００１８】
本考案のプッシュ・スイッチ連動構造の実施時、即ち使用に際しては、図３、図４、図５、図６を参照して説明すると、図３はスイッチがオフ（ＯＦＦ）に位置する状態を示す。このとき、ユーザーがプッシュ・キー１のカバー１０を押すと、プッシュ・キー１は下がり、定位エレメント１４も連動して下向きに下がり、定位エレメント１４の凸レバー１４２は環状階段路２２の中で、斜状凸部２３の上側面から左下方に移動し、逆時計回りで環状階段路２２のルートに沿って斜状凸部２３の下側面まで移動する。該定位エレメント１４の凸レバー１４２は定位連動片３のあけ孔３１と接触してあけ孔３１を推し動かし、これにより定位連動片３は左向きに回る。図４に示すように、あけ孔３１の右下にあるへこみ（Ａ点）はほぼ水平状態で、環状階段路２２の斜状凸部２３の左下側面と接触している。プッシュ・キー１を離すと、定位エレメント１４の凸レバー１４２は環状階段路２２の斜状凸部２３の左下側面に沿ってあけ孔３１の右下にあるへこみ（Ａ点）までスライドし、定位エレメント１４を引き下げる状態にセッティングされる。図５に示すように、定位エレメント１４を引き下げる状態にセッティングすると、定位連動片３は凸レバー１４２が推し動かされたこよによって連動され、接合孔３２を中心軸として左向き（逆時計方向）に回される。それと同時に定位連動片３の鉤部３３は上向きに回転し、鉤溝３３２が弾性接触片４の可動端を挟んで上に持ち上げ、これによって、弾性接触片４の弾性チップ４２が反対向きに跳ね上がり、弾性チップ４２の自由端の第１接点４２２は下に下がって第２接点２６２と接触し、電気回路の通電状態（ＯＮ）が形成する。
【００１９】
図５はスイッチが通電（ＯＮ）に位置する状態を示す。このとき、ユーザーが、プッシュ・キー１のカバー１０を押すと、プッシュ・キー１は下がり、定位エレメント１４も連動して下向きに下がり、定位エレメント１４の凸レバー１４２は環状階段路２２の中で、左下方向に少し移動する。該定位エレメント１４の凸レバー１４２は定位連動片３のあけ孔３１のＡ点を右に推し動かし、よって定位連動片３は右に回る。あけ孔３１の右下にあるへこみ（Ａ点）の内側縁部は元のほぼ水平状態から垂直に近くまで回されて傾斜状となり、環状階段路２２中の斜状凸部２３の上端部との間に開口を形成する。図６に示すように、このとき、定位エレメント１４の凸レバー１４２はあけ孔３１右下にあるへこみ（Ａ点）内側縁部の制限を失ったため、プッシュ・キー１内部の弾性エレメント１２（圧縮ばね）の弾力によってプッシュ・キ−１及び定位エレメント１４を上向きに跳ね上げる。定位エレメント１４の凸レバー１４２は環状階段路２２レールに沿って上に上がり、定位連動片３のあけ孔３１の制限を受けて定位連動片３のへこみ（Ｂ点）までに達する。これによって、定位エレメント１４の凸レバー１４２は、図３に示すように、環状階段路２２の斜状凸部２３の左上側面まで移動し、定位エレメント１４及びプッシュ・キー１を引き上げる状態にセッティングする。図５、図６から図３までの過程では、定位エレメント１４は右下方向に移動すると、凸レバー１４２はあけ孔３１右下にあるへこみ（Ａ点）を推し動かし、定位連動片３は接合孔３２を中心軸として右方向（時計回り）に回る。これと同時に、定位連動片３の鉤部３３を連動させて下に下げり、鉤部３３の鉤溝３３２は弾性接触片４の可動端を挟んで下に下がり、これによって、弾性接触片４の弾性チップ４２は反対に上向きに跳ね上がり、弾性チップ４２の自由端の第１接点４２２も上に上がり、第２接点２６２と分離し、電気回路を切断状態（ＯＦＦ）にする。
【００２０】
図５に示すように、スイッチが通電（ＯＮ）の状態に位置する場合、電流は過負荷になると、弾性接触片４は熱を受けて変形し、反対方向に彎曲する（下向きに彎曲）。弾性接触片４の可動端は下向きに跳ね、弾性接触片４の弾性チップ４２を反対の上方向へ跳ね上げ、これによって、弾性チップの自由端にある第１接点４２２も上に上がり、第２接点２６２と分離し、電気回路を切断状態（ＯＦＦ）にする。これと同時に弾性接触片４の可動端は下向きに跳ね、連動して鉤部３３を下に下げ、定位連動片３は接合孔３２を中心軸として右に回り（時計回り）、環状階段路２２中の斜状凸部２３の上端部に開口を形成する。図７に示すように、このとき、定位エレメント１４の凸レバー１４２はあけ孔３１の右下にあるへこみ（Ａ点）の制限を失い、プッシュ・キー１内部の弾性エレメント１２（圧縮ばね）の弾性によりプッシュ・キー１及び定位エレメント１４を上に跳ね上げ、定位エレメント１４の凸レバー１４２は環状階段路２２のルートに沿って上に上がり、あけ孔３１の制限を受けて上端のへこみ（Ｂ点）に達する。これによって定位エレメント１４の凸レバー１４２は（図３に示すように）環状階段路２２中の斜状凸部２３の左上側面まで移動し、定位エレメント１４及びプッシュ・キー１を引き上げ状態にセッティングする。これは、電流過負荷による分離及びプッシュ・キー１と定位エレメント１４が同時に連動されて一般切断（ＯＦＦ）され、再使用状態への回復過程となる。
【００２１】
【発明の効果】上記述べたように、本考案はプッシュ・キー１と定位エレメント１４を同調して上下に動作することにより、定位エレメント１４がスイッチ・ボックス２の環状階段路２２及び定位連動片３と相互に連動して、循環セッティング関係を形成し、そして定位連動片３の鉤部３３により弾性接触片４を跳ねるようと推し動かし、スイッチが通電する（ＯＮ）又は切断する状態（ＯＦＦ）を形成する。そのほか、本考案は電流が過負荷になる場合、即時に電源を切断（ＯＦＦ）し、同時にプッシュ・キー１を一般的切断（ＯＦＦ）、即ち再使用状態に回復する機能を有する。本考案の構成部品は簡単で、各部品の動作関係も直接的なものであり、操作を確実に且つ効率的にしている。本考案には、確実な効果が見られ、いままでにない新しい設計で、特許法の進歩性などの諸要件と一致する。

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push-switch interlocking structure. More specifically, according to the present invention, when the push switch is pressed, the localization element operates in synchronization, and the localization element, the annular stairway and the localization interlocking piece interlock with each other to form a circulating setting relationship. The interlocking piece jumps up in direct association with the elastic contact piece, forming a state in which the switch is energized (ON) or disconnected (OFF). In addition, when the current is overloaded, the elastic contact piece is deformed by heat. The contact of the elastic contact piece is separated from the other contact, and the switch structure is in a state where the electric circuit is disconnected (OFF), and at the same time, the elastic contact piece directly pushes the localization interlocking piece and moves again to the original state. The present invention relates to a push-switch interlocking structure that can be turned to a use state.

2. Description of the Related Art In the operation of a general power switch, the most important point lies in two operation processes of energization and disconnection. In order to ensure that the interlocking operation of the components inside the switch is performed efficiently and efficiently, and to simplify the switch components and reduce the manufacturing cost, research and improvement of the switch structure are important joint issues for manufacturers.
[0003]
There are a number of prior patents for switch structures, for example, U.S. Pat. Nos. 4,167,720, 4,937,548, 5,223,813, 5,451,729, and No. 5,558,211 and so on. However, all of these prior patents have the following common drawbacks.
[0004]
(1) Since there are many interlocking components and the interlocking process is complicated, the operation relationship between the push key and the end component is shifted, and the manufacturing cost is high.
(2) Since the operation relationship is uncertain, the number of failure cases increases, and safety in use is lacking.
(3) Since the push key directly or indirectly presses the elastic contact piece to energize or cut, the poor contact or tear is likely to occur, lowering the energization quality and shortening the service life.
[0005]

No. 5,223,813 is shown in FIGS. 8, 9, and 10, when the push key 33 is pressed, the interlocking lever 39 below the push key interlocks, and through the part 27 that slides up and down connected by the interlocking lever, the lower part thereof is moved downward. An electric circuit is turned on or off by pressing or releasing a certain elastic contact piece 5 to make contact with its upper contact 7 or to separate it from the lower contact 1. This is a method in which the push keys indirectly work together to press or release the resilient contact pieces. Under ideal conditions, there is no problem in operation and use, but the components are complicated. Therefore, there are still obvious disadvantages such as high manufacturing cost, increased operation failure, delay of reaction in the interlocking process and potential tearing or elastic fatigue of the elastic contact piece, and a common issue between manufacturers and users.
