Description

【０００１】
【発明の属する技術分野】
本発明は、遠隔操縦するリモコン装置等に関し、詳しくは１つの操作部での押動操作にて、２段階にスイッチ操作し、例えばクレーン等の遠隔操縦におけるクレーンの動作速度を２段階に調節できるようにする段押しスイッチ機構に関するものである。
【０００２】
【従来の技術】
従来、１つの操作部での押動操作にて２段階のスイッチ操作が可能な段押しスイッチ機構では、上下揺動可能なように弾性支持されたスイッチ操作部材の１箇所に操作部を設けるとともに、この操作部に与えられた押動力が第１のスイッチ押動体を介し第１のスイッチに優先的に働いた後、第２のスイッチ押動体を介し第２のスイッチに働かせる構造が提案されている。例えば、特開平６−２８９４８号公報での段押しスイッチ装置の構成例を図３３、図３４で以下に説明する。
【０００３】
図３３、図３４において、キー１３１は、操作パネル１７の透孔１５１内に位置してスイッチ操作部材をなし、操作パネル１７の透孔１５１の口縁一部と樹脂ばね１５２を介して操作パネル１７に一体形成され、樹脂ばね１５２部の弾性変形を伴って下動されて対応するスイッチ１４１、１４２のアクチュエータ１４１ａ、１４２ａを押動操作でき、操作後は樹脂ばね１５２の弾性復元力によって通常位置に復帰できるようにしている。
【０００４】
更にキー１３１は、互いに離れた位置で下向きに形成されている第１、第２の各スイッチ押動突起１３１ａ、１３１ｂを備えている。キー１３１の第１、第２の各スイッチ押動突起１３１ａ、１３１ｂの間の第１のスイッチ押動突起１３１ａ寄りに操作部１３１ｃを設け、操作部１３１ｃへの押動が第１の押動突起１３１ａに優先的に働いた後、第１のスイッチ押動突起１３１ａによる第１のスイッチ１４１のアクチュエータ１４１ａの押動点を支点として第２のスイッチ押動突起１３１ｂに働くようにしている。
【０００５】
これによって、キー１３１の操作部１３１ｃに与えられた押動操作力は第１のスイッチ押動突起１３１ａの側に優先的に働いてこれを第１のスイッチ１４１のアクチュエータ１４１ａに押し付けて第１のスイッチのみを押動操作するようにできる。
【０００６】
この時第２のスイッチ押動突起１３１ｂの側も下動されるが、キー１３１自身の弾性によって逃げが生じることにより、第２のスイッチ１４２のアクチュエータ１４２ａに接するまで下動されないか、下動されてもこれを押動するまでの操作力は伝達されない。
【０００７】
操作部１３１ｃがそれ以上に押動されるとキー１３１は第１のスイッチ押動突起１３１ａによる第１のスイッチ１４１のアクチュエータ１４１ａに対する前記押動点を支点として揺動されて第２のスイッチ押動突起１３１ｂによる第２のスイッチ１４２のアクチュエータ１４２ａに押し付けて第１のスイッチ１４１を押動操作状態に保ちながら、第２のスイッチ１４２を押動操作することができる。
【０００８】
また第１のスイッチ押動突起１３１ａと第１のスイッチ１４１のアクチュエータ１４１ａとの対向間隔Ｓ１を、第２のスイッチ押動突起１３１ｂと第２のスイッチ１４２のアクチュエータ１４２ａとの対向間隔Ｓ２よりも小さく設定している。
【０００９】
したがって、キー１３１の操作部１３１ｃに受ける初期押動操作力が第１のスイッチ押動突起１３１ａに優先的に働くことによる第１のスイッチ１４１の単独での押動操作が確実に行うことができると記載されている。
【００１０】
【発明が解決しようとする課題】
しかしながら上記従来の構成では、操作部１３１ｃへの押動が第１の押動突起１３１ａによる第１のスイッチ１４１のアクチュエータ１４１ａに優先的に働き、更に操作部１３１ｃを押動することにより、前記第１のスイッチ１４１のアクチュエータ１４１ａの押動点が支点となり、第２の押動突起１３１ｂが第２のスイッチ１４２のアクチュエータ１４２ａを押動するため、常に第１のスイッチ１４１のアクチュエータ１４１ａに過負荷な荷重が掛かる状態であり、更に第１のスイッチ１４１と第２のスイッチ１４２が両方押動された状態においても、操作部１３１ｃを押動し続けると、両方のスイッチのアクチュエータに過負荷な荷重が掛かって、スイッチ本来の操作寿命を低下させることとなり、また、キー１３１が樹脂ばね１５２を一体で構成され、前記樹脂ばね１５２の弾性復元力の範囲内でしか、操作後のキー１３１を通常位置に復帰させることができないために、スイッチ単独のストロークが小さなものしか選択できず、第１のスイッチ押動突起１３１ａと第１のスイッチ１４１のアクチュエータ１４１ａとの対向間隔Ｓ１と、第２のスイッチ押動突起１３１ｂと第２のスイッチ１４２のアクチュエータ１４２ａとの対向間隔Ｓ２の差を大きく設定することができないので、１段目と２段目の操作間隔の明確な違い（クリック感）をもたらすことができないという課題があった。
【００１１】
本発明はこのような従来の課題を解決し、スイッチ本来の操作寿命を低下させること無く、スイッチ単独の操作ストロークが小さな場合であっても、実際の操作部でのストロークを十分確保できるとともに、１段目と２段目の操作間隔（クリック感）を明確にすることができる段押しスイッチ機構を提供することを目的とするものである。
【００１２】
【課題を解決するための手段】
この課題を解決するために本発明による段押しスイッチ機構は、第１の支点軸と少なくとも２箇所以上の第１の爪部を有し、前記第１の支点軸の長手方向に対して直角に離れた位置で垂直方向に伸びた第１のスイッチ押動突起と、前記第１のスイッチ押動突起と同一中心線上に第１の操作部が設けられた第１のスイッチボタンと、第２の支点軸と少なくとも２箇所以上の第２の爪部を有し、前記第２の支点軸の長手方向に対して直角に離れた位置で垂直方向に伸びた第２のスイッチ押動突起と、前記第２のスイッチ押動突起の中心線から平行線上に２箇所以上の第２の操作部が設けられた第２のスイッチボタンと、前記第１、第２のスイッチボタンに設けられた第１、第２の支点軸に嵌合保持する第１及び第２の支点軸受けと、第１、第２の少なくとも２箇所以上設けられた爪部を係止する第１、第２の係止穴と、第１、第２のスイッチ押動突起をガイドする第１、第２のガイド穴を有するスイッチスペーサと、前記第１、第２のスイッチボタンの第１、第２のスイッチ押動突起と相対する位置に、第１、第２のスイッチが実装されたプリント基板と、前記第１、第２のスイッチボタンの第１、第２のスイッチ押動突起が、無操作状態では常に前記第１、第２のスイッチに接触しない通常状態位置に跳ね上げておくための第１、第２の跳ね上げバネと、前記第１、第２のスイッチボタンの第１、第２の操作部と相対する位置に一定の肉厚を保持した内面が空洞で凸状態にある操作部と、前記操作部上面に表示銘板を貼り付けるための段部と、裏面には前記第１、第２のスイッチボタンの第１、第２の操作部に相対する位置に段差を有した第１、第２の突起が設けられたスイッチボードと、前記スイッチボードの操作部と相対する位置に開口部を設けた第１ケースを備えた構成としたものである。
【００１３】
この本発明によれば、スイッチ本来の操作寿命を低下させること無く、スイッチ単独の操作ストロークが小さな場合であっても、実際の操作部でのストロークを十分確保できるとともに、１つの操作部での押動操作で、２段階にスイッチ操作ができ、且つ１段目と２段目の操作間隔（クリック感）を明確にすることができる段押しスイッチ機構が得られる。
【００１４】
【発明の実施の形態】
本発明の請求項１に記載の発明は、第１の支点軸と少なくとも２箇所以上の第１の爪部を有し、前記第１の支点軸の長手方向に対して直角に離れた位置で垂直方向に伸びた第１のスイッチ押動突起と、前記第１のスイッチ押動突起と同一中心線上に第１の操作部が設けられた第１のスイッチボタンと、第２の支点軸と少なくとも２箇所以上の第２の爪部を有し、前記第２の支点軸の長手方向に対して直角に離れた位置で垂直方向に伸びた第２のスイッチ押動突起と、前記第２のスイッチ押動突起の中心線から平行線上に２箇所以上の第２の操作部が設けられた第２のスイッチボタンと、前記第１、第２のスイッチボタンに設けられた第１及び第２の支点軸に嵌合保持する第１、第２の支点軸受けと、第１、第２の少なくとも２箇所以上設けられた爪部を係止する第１、第２の係止穴と、第１、第２のスイッチ押動突起をガイドする第１、第２のガイド穴を有するスイッチスペーサと、前記第１、第２のスイッチボタンの第１、第２のスイッチ押動突起と相対する位置に、第１、第２のスイッチが実装されたプリント基板と、前記第１、第２のスイッチボタンの第１、第２のスイッチ押動突起が、無操作状態では常に前記第１、第２のスイッチに接触しない通常状態位置に跳ね上げておくための第１、第２の跳ね上げバネと、前記第１、第２のスイッチボタンの第１、第２の操作部と相対する位置に一定の肉厚を保持した内面が空洞で凸状態になった操作部と、前記操作部上面に表示銘板を貼り付けるための段部と、互いに段差を有する第１、第２の突起が、前記第１、第２のスイッチボタンの第１、第２の操作部の相対する位置に設けられたスイッチボードと、前記スイッチボードの操作部と相対する位置に開口部を設けた第１ケースを備えた構成を有しているので、前記第１、第２のスイッチボタンに設けられた第１、第２の支点軸を支点とした前記第１、第２のスイッチ押動突起までの距離と、前記第１、第２の操作部までの距離との差と、更に前記スイッチボードの操作部の裏面に設けた第１、第２の突起の段差により、スイッチ単独のストロークが小さくても、実際の操作で手が触れるスイッチボードの操作部でのストロークが大きく設定できるとともに、１つの操作部での押動操作にて、２段階にスイッチ操作ができ、且つ１段目と２段目の操作間隔（クリック感）を明確にすることができるという作用を有する。
【００１５】
更に、第２のスイッチボタンの操作部を押動しても第１のスイッチを支点としていないので、スイッチ本来の操作寿命を低下させることが無いという作用も有する。
【００１６】
本発明の請求項２に記載の発明は、請求項１記載の発明において、前記第１、第２のスイッチボタンの第１、第２の操作部に、前記スイッチボードの裏面に設けられた第１、第２の突起と相対する位置に第１、第２のセンタリング穴を設けた構成を有しているので、前記スイッチボードの操作部を押動すると、スイッチボードの操作部の裏面に設けられた第１、第２の突起が、前記第１、第２のスイッチボタンの第１、第２の操作部に接触した時に、第１、第２の突起の先端が第１、第２の操作部に設けられたセンタリング穴でセンタリングされて確実な押動力が伝達できるという作用を有する。
【００１７】
本発明の請求項３に記載の発明は、請求項１記載の発明において、前記第１、第２のスイッチボタンの第１、第２の操作部の裏面に、前記スイッチボードの操作部の裏面に設けられた第１、第２の突起と相対する位置に垂直方向に延びた第１、第２のメカストッパーを設けた構成を有しているので、前記スイッチボードの操作部を押動すると、スイッチボードの操作部の裏面に設けられた第１、第２の突起が、前記第１、第２のスイッチボタンの第１、第２の操作部を押動し、第１、第２のスイッチがＯＮ−ＯＦＦした時、前記メカストッパーが前記スイッチスペーサにあたり、スイッチボードの操作部を更に押動してもスイッチには過負荷な荷重が掛かることを防止することができるという作用を有する。
【００１８】
本発明の請求項４に記載の発明は、請求項１記載の発明において、前記第１、第２のスイッチボタンに設けられた第１、第２のスイッチ押動突起の先端に段付き状態のガイドピンを一体で設け、前記ガイドピンに嵌合する挿入穴を有したスイッチボタンゴムで構成を有しているので、前記第１、第２のスイッチボタンの第１、第２の操作部の裏面に垂直に延びた第１、第２のメカストッパーで、第１、第２のスイッチ押動突起の下死点が一定となるので、第１、第２のスイッチ押動突起の先端に前記スイッチボタンゴムをつけることにより、スイッチのＯＮ−ＯＦＦ接点位置のバラツキ、部品実装時の高さバラツキ等があっても、スイッチボタンゴムの弾性範囲内で確実にスイッチをＯＮ−ＯＦＦさせることができるという作用を有する。
【００１９】
本発明の請求項５に記載の発明は、請求項１記載の発明において、前記スイッチボタンゴムの外周部に湾曲状に形成されたツバ部を全周に一体で構成を有しているので、スイッチのＯＮ−ＯＦＦ接点位置のバラツキ、部品実装時の高さバラツキがあっても、スイッチボタンゴムの弾性範囲内で確実にスイッチをＯＮ−ＯＦＦさせることができるという作用と、操作後はスイッチボタンゴムの外周部全周に湾曲状に一体に形成されたツバ部の弾性復元力で、第１、第２のスイッチボタンを通常位置に復帰させることができるという作用を有する。
【００２０】
本発明の請求項６に記載の発明は、請求項１記載の発明において、前記第１のスイッチボタンと前記第１のスイッチ又は前記第２のスイッチボタンと前記第２のスイッチのどちらか一方で構成を有しているので、段押しスイッチ機構が不要な場合は、第１のスイッチボタンと第１のスイッチ又は第２のスイッチボタンと第２のスイッチのどちらか一方を除くことで単独のスイッチ操作ができるという作用を有する。
【００２１】
本発明の請求項７に記載の発明は、請求項１記載の発明において、前記スイッチボードの外周部にツバ部を設け、前記ツバ部を第１のケースと端面に断面形状が三角形又は半円形をした凸部を有した第２のケースとで挟み込む構成を有しているので、段押しスイッチ機構とケース内部への液体の侵入防止がスイッチボード単独で構成することができるという作用を有する。
【００２２】
本発明の請求項８に記載の発明は、請求項３記載の発明において、前記第１のスイッチボタンの第１の操作部の中央に段差を有した貫通ガイド穴を設け、前記段差を有した貫通ガイド穴に挿入する先端が球Ｒ形状でリング溝を有したスイッチ可動ピンと、前記スイッチ可動ピンと前記段差を有したガイド穴との間に配置する第３の跳ね上げバネと、前記スイッチ可動ピンのリング溝に嵌合する抜け止めリングと、前記スイッチスペーサの第１、第２のガイド穴の中間位置に逃がし穴を設け、前記第２のスイッチボタンの第２の操作部に球Ｒ形状の突起を設け、前記第１、第２のスイッチボタンの第１、第２の操作部に相対する位置に一定の肉厚を保持した内面が空洞で凸状態になった操作部の裏面を平滑面で構成を有しているので、前記第１、第２のスイッチボタンに設けられた第１、第２の支点軸を支点とした前記第１、第２のスイッチ押動突起までの距離と、前記第１、第２の操作部までの距離との差と、前記第１のスイッチボタンの操作部に配置されたスイッチ可動ピンの突出量と第２のスイッチボタンの操作部に設けられた突起の突出量との差により、１つの操作部での押動操作にて、２段階にスイッチ操作ができ、且つ１段目と２段目の操作間隔（クリック感）を明確にすることができるという作用を有する。
【００２３】
更に、スイッチボードの操作部裏面が平滑面で且つ、第１のスイッチボタンの操作部に配置されたスイッチ可動ピンの先端が球Ｒ形状である為に、スイッチボードの操作部をあらゆる方向から押動操作しても、確実に２段階のスイッチ操作ができ、スイッチ可動ピンが押動操作によって上下することによりスイッチボードの操作部裏面だけに弾性変形負荷が集中することが軽減でき、且つ第１のスイッチボタンの操作部とスイッチ可動ピンとの間に配置された第３の跳ね上げバネの荷重設定により１段目と２段目の操作間隔（クリック感）をより明確にすることができるという作用を有する。
【００２４】
本発明の請求項９に記載の発明は、請求項３記載の発明において、前記第１のスイッチボタンの第１の操作部の中央に凹みガイド穴を設け、前記凹みガイド穴に挿入・嵌合する段付形状で先端が球Ｒ形状をしたスイッチゴムと、前記第２のスイッチボタンの第２の操作部に球Ｒ形状の突起を設け、前記第１、第２のスイッチボタンの第１、第２の操作部に相対する位置に一定の肉厚を保持した内面が空洞で凸状態になった操作部の裏面に前記第１のスイッチボタンの第１の操作部に相対する位置にだけ設けた第３の突起を構えた構成を有しているので、前記第１、第２のスイッチボタンに設けられた第１、第２の支点軸を支点とした前記第１、第２のスイッチ押動突起までの距離と、前記第１、第２の操作部までの距離との差と、スイッチボードの操作部裏面に設けられた突起と平滑面との差により、１つの操作部での押動操作にて、２段階にスイッチ操作ができ、且つ１段目と２段目の操作間隔（クリック感）を明確にすることができるという作用を有する。
【００２５】
更に、押動操作によって、スイッチボードの操作部裏面に設けられた第３の突起と第１のスイッチボタンの操作部に配置されたスイッチゴムとがお互いに弾性変形しあうことで、スイッチボードの操作部裏面だけに弾性変形負荷が集中することが軽減でき、且つスイッチボードの操作部とスイッチゴムのゴム硬度の設定により１段目と２段目の操作間隔（クリック感）をより明確にするという作用を有する。
【００２６】
本発明の請求項１０に記載の発明は、請求項３記載の発明において、前記第１のスイッチボタンの第１の操作部に凹みガイド穴と前記凹みガイド穴の中央にガイドボスを設け、前記凹みガイド穴の中央に設けたガイドボスに挿入・嵌合するスイッチ可動バネと、前記第２のスイッチボタンの第２の操作部に球Ｒ形状の突起を設け、前記第１、第２のスイッチボタンの第１、第２の操作部に相対する位置に一定の肉厚を保持した内面が空洞で凸状態になった操作部の裏面を前記第１のスイッチボタンの第１の操作部に相対する位置だけに突起を設けた構成を有しているので、前記第１、第２のスイッチボタンに設けられた第１、第２の支点軸を支点とした前記第１、第２のスイッチ押動突起までの距離と、前記第１、第２の操作部までの距離との差と、前記スイッチボードの操作部裏面に第１のスイッチボタンの操作部だけに相対する位置だけに設けた突起と平滑部との差により、１つの操作部での押動操作にて、２段階にスイッチ操作ができ、且つ１段目と２段目の操作間隔（クリック感）を明確にすることができるという作用を有する。
【００２７】
更に、押動操作によって、スイッチ可動バネが圧縮変形することによりスイッチボードの操作部裏面だけに弾性変形負荷が集中することが軽減でき、且つスイッチ可動バネの荷重設定による１段目と２段目の操作間隔（クリック感）をより明確にすることができるという作用を有する。
【００２８】
本発明の請求項１１に記載の発明は、請求項３記載の発明において、前記第１のスイッチボタンの第１の操作部に相当する位置に先端が湾曲形状に形成されたスイッチ板ばねを配置し、前記第２のスイッチボタンの第２の操作部に球Ｒ形状の突起を設け、前記第１、第２のスイッチボタンの第１、第２の操作部に相対する位置に一定の肉厚を保持した内面が空洞で凸状態になった操作部の裏面を平滑面で構成を有しているので、前記第１、第２のスイッチボタンに設けられた第１、第２の支点軸を支点とした前記第１、第２のスイッチ押動突起までの距離と、前記第１、第２の操作部までの距離との差と、前記第１のスイッチボタンの操作部に配置されたスイッチ板バネの湾曲形状部の突出量と第２のスイッチボタンの操作部に設けられた突起の突出量との差により、１つの操作部での押動操作にて、２段階にスイッチ操作ができ、且つ１段目と２段目の操作間隔（クリック感）を明確にすることができるという作用を有する。
【００２９】
更に、押動操作によって、スイッチ板バネが弾性変形することによりスイッチボードの操作部裏面だけに弾性変形負荷が集中することが軽減でき、且つスイッチ板バネの荷重設定による１段目と２段目の操作間隔（クリック感）をより明確にすることができるという作用を有する。
【００３０】
以下、本発明の実施の形態について、図１〜図３２を用いて説明する。
【００３１】
（実施の形態１）
図１は本発明の第１の実施の形態における段押しスイッチ機構を示す分解構成斜視図であり、図２（ａ）は同実施の形態１による第１、第２のスイッチボタンの配置状態を示す要部平面図であり、図２（ｂ）は図２（ａ）のＢ−Ｂ’で断面した第１のスイッチボタンの通常状態を示す断面図であり、図２（ｃ）は図２（ａ）のＣ−Ｃ’で断面した第２のスイッチボタンの通常状態を示す断面図であり、図３（ａ），（ｂ）は第１、第２のスイッチボタンが押動された状態を示す要部断面図である。図１、図２、図３において、１、２は各々支点軸１ａ、２ａと少なくとも２箇所以上の各々爪部１ｂ、２ｂを有した第１、第２のスイッチボタン、１ｃ、２ｃは各々支点軸１ａ、２ａの長手方向に対して直角に離れた位置に各々垂直方向に伸びたスイッチ押動突起、１ｄ、２ｄはスイッチ押動突起１ｃ、２ｃと同一中心線上及び平行線上に各々設けられた操作部である。３は前記第１、第２のスイッチボタン１、２に各々設けられた支点軸１ａ、２ａを保持する支点軸受け３ｃ、３ｄと、第１、第２のスイッチ押動突起１ｃ、２ｃを各々ガイドするガイド穴３ａ、３ｂと、爪部１ｂ、２ｂを各々係止する係止穴３ｅ、３ｆを一体で構成したスイッチスペーサ、４、５は前記第１、第２のスイッチボタン１、２を通常状態に跳ね上げておく跳ね上げバネ、６は第１、第２のスイッチ７、８が実装されたプリント基板、９は前記第１、第２のスイッチボタン１、２の操作部１ｄ、２ｄと相対する位置に一定の肉厚を保持した内面が空洞で凸状態にある操作部９ａと、前記操作部９ａ上面に表示銘板１１を貼り付けるための段部９ｄと、前記操作部９ａの裏面に前記第１、第２のスイッチボタン１、２の操作部１ｄ、２ｄと相対する位置に段差を有した第１、第２の突起９ｂ、９ｃが弾性体で一体構成されたスイッチボード、１０は前記スイッチボード９に設けられた操作部９ａと相対した位置に開口部１０ａを有する第１のケースである。
【００３２】
上記の構成において、ガイド穴３ａ、３ｂの外周部に跳ね上げバネ４、５を配置し、支点軸受け３ｃ、３ｄに第１、第２のスイッチボタンの支点軸１ａ、２ａを嵌合するとともに、爪部１ｂ、２ｂを係止穴３ｅ、３ｆに係止するまで挿入することで、第１、第２のスイッチボタン１、２は跳ね上げバネ４、５のバネ力で通常状態位置に跳ね上げられた状態となる。次に第１、第２のスイッチボタン１、２が装着されたスイッチスペーサ３を第１、第２のスイッチが実装されたプリント基板６の上にのせ、ネジ等の手段によって固定する。更にスイッチスペーサ３の上面にスイッチボード９と第１のケース１０を被せることで、スイッチボード９の第１、第２の突起９ｂ、９ｃが第１、第２のスイッチボタンの第１、第２の操作部１ｄ、２ｄと相対する位置に配置されるとともに、第１の突起９ｂと第１の操作部１ｄはほぼ隙間の状態となり、スイッチボード９の操作部９ａを押動操作すると、まず図３（ａ）に示すように第１の突起９ｂが第１のスイッチボタン１の操作部１ｄを押し下げると連動して、第１のスイッチ押動突起１ｃが第１のスイッチ７に働き、更に押動操作すると第１の突起９ｂが弾性変形しながら、図３（ｂ）に示すように第２の突起９ｃが第２のスイッチボタンの操作部２ｄを押し下げると連動して第２の押動突起２ｃによって第２のスイッチ８に働くようにしてある。
【００３３】
以上のように同実施の形態１によれば、前記第１、第２のスイッチボタンに設けられた第１、第２の支点軸を支点とした前記第１、第２のスイッチ押動突起までの距離と、前記第１、第２の操作部までの距離との差と、更に前記操作部材の凸部の裏面に設けた第１、第２の突起の段差により、スイッチ本来の操作寿命を低下させること無く、スイッチ単独のストロークが小さくても、実際の操作で手が触れるスイッチボードの操作部でのストロークが大きく設定できるとともに、１つの操作部での押動操作にて、２段階にスイッチ操作ができ、且つ１段目と２段目の操作間隔（クリック感）を明確にすることができるという効果が得られる。
【００３４】
なお、本実施の形態では、スイッチボード９に段差を設けた突起９ｂ、９ｃを設けた構成を図示したが、第１、第２のスイッチボタン１、２の操作部１ｄ、２ｄに同様の段差を設けた突起を構成しても同様の効果が得られる。
【００３５】
（実施の形態２）

BACKGROUND OF THE INVENTION
The present invention relates to a remote control device or the like for remote control, and more specifically, a switch operation is performed in two stages by a push operation with one operation unit, and for example, an operation speed of a crane in remote control such as a crane can be adjusted in two stages. The present invention relates to a step push switch mechanism.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in a step push switch mechanism capable of two-step switch operation by a push operation with one operation portion, an operation portion is provided at one place of a switch operation member that is elastically supported so as to be swingable up and down. A structure has been proposed in which the pressing force applied to the operation section is preferentially applied to the first switch via the first switch pusher, and then is applied to the second switch via the second switch pusher. Yes. For example, a configuration example of the step push switch device disclosed in Japanese Patent Laid-Open No. 6-28948 will be described below with reference to FIGS.
[0003]
33 and FIG. 34, the key 131 is located in the through hole 151 of the operation panel 17 to form a switch operation member. The actuator 141a, 142a of the corresponding switch 141, 142 can be pushed and operated by being elastically deformed by the resin spring 152, and after the operation, the normal position can be obtained by the elastic restoring force of the resin spring 152. To be able to return to.
[0004]
Further, the key 131 includes first and second switch pushing protrusions 131a and 131b formed downward at positions away from each other. An operating portion 131c is provided near the first switch pushing projection 131a between the first and second switch pushing projections 131a and 131b of the key 131, and the pushing to the operating portion 131c is the first pushing projection. After preferentially acting on 131a, the first switch pushing projection 131a acts on the second switch pushing projection 131b with the pushing point of the actuator 141a of the first switch 141 as a fulcrum.
[0005]
As a result, the pressing operation force given to the operating portion 131c of the key 131 works preferentially on the first switch pressing protrusion 131a side, and presses this against the actuator 141a of the first switch 141, thereby causing the first switch pressing protrusion 131a to press. Only the switch can be pushed.
[0006]
At this time, the second switch pushing protrusion 131b side is also moved downward, but due to the elasticity of the key 131 itself, the second switch 142 is not moved downward or is moved downward until it comes into contact with the actuator 142a. However, the operating force until it is pushed is not transmitted.
[0007]
When the operation unit 131c is further pushed, the key 131 is swung around the pushing point of the first switch 141 with respect to the actuator 141a by the first switch pushing protrusion 131a as a fulcrum, thereby pushing the second switch. The second switch 142 can be pushed while being pressed against the actuator 142a of the second switch 142 by the protrusion 131b to keep the first switch 141 in the pushing operation state.
[0008]
The facing distance S1 between the first switch pushing protrusion 131a and the actuator 141a of the first switch 141 is smaller than the facing distance S2 between the second switch pushing protrusion 131b and the actuator 142a of the second switch 142. It is set.
[0009]
Therefore, the first switch 141 alone can be reliably pushed by the initial push operation force received by the operation portion 131c of the key 131 preferentially acting on the first switch push protrusion 131a. It is described.
[0010]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, the pushing to the operation unit 131c preferentially acts on the actuator 141a of the first switch 141 by the first pushing projection 131a, and further pushes the operation unit 131c, thereby Since the pushing point of the actuator 141a of the first switch 141 serves as a fulcrum and the second pushing projection 131b pushes the actuator 142a of the second switch 142, the actuator 141a of the first switch 141 is always overloaded. Even when both the first switch 141 and the second switch 142 are pushed, even if both the first switch 141 and the second switch 142 are pushed, an excessive load is applied to the actuators of both switches. This reduces the operating life of the switch, and the key 131 causes the resin spring 152 to move. Since the key 131 after the operation can be returned to the normal position only within the range of the elastic restoring force of the resin spring 152, only the switch having a small stroke can be selected. The difference between the facing distance S1 between the switch pushing protrusion 131a and the actuator 141a of the first switch 141 and the facing distance S2 between the second switch pushing protrusion 131b and the actuator 142a of the second switch 142 are set large. Therefore, there is a problem that a clear difference (click feeling) between the operation intervals of the first stage and the second stage cannot be brought about.
[0011]
The present invention solves such a conventional problem, and even if the operation stroke of the switch alone is small without reducing the original operation life of the switch, the stroke in the actual operation unit can be sufficiently secured, An object of the present invention is to provide a step push switch mechanism capable of clarifying the operation interval (click feeling) between the first step and the second step.
[0012]
[Means for Solving the Problems]

And an operation part in which the inner surface of the first and second switch buttons facing the first and second operation parts has a constant thickness and is hollow and convex, and is displayed on the upper surface of the operation part. The first and second switch buttons on the step for pasting the nameplate and the back A switch board provided with first and second protrusions having a step at a position opposite to the first and second operation parts, and an opening provided at a position opposite to the operation part of the switch board. It is set as the structure provided with 1 case.
[0013]
According to the present invention, even if the operation stroke of the switch alone is small without reducing the original operation life of the switch, the stroke in the actual operation unit can be sufficiently secured and the operation in one operation unit can be secured. By the push operation, the switch operation can be performed in two steps, and a step push switch mechanism that can clarify the operation interval (click feeling) between the first step and the second step is obtained.
