Description

【０００１】
【発明の属する技術分野】
本発明は、釦部を押し込むことによりスイッチを切り替えるようにしたスイッチ装置に関するものである。
【０００２】
【従来技術】
従来、この種のスイッチ装置は、パネル等の保持部の開口部分内に進退可能に挿入されて操作者により押圧される釦部と、釦部の下方に配置したリターンスプリングとを備え、リターンスプリングで釦部を保持部側へ押し戻すようにしていた。
【０００３】
【発明が解決しようとする課題】
しかし、このような従来のスイッチ装置では、釦部が単に保持部の開口部分に挿入されていただけであったため、保持部に対する釦部の位置決め精度がよくなく、操作中に釦部が開口部分にひっかかって作動不良になる場合があるという問題があった。
本発明はこのような問題を解決するためになされたもので、操作中の釦部の引っかかりを防ぐことができるようにしたスイッチ装置を提供するものである。
【０００４】
【課題を解決するための手段】
本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えた構成を有している。この構成により釦部が互いに逆方向から弾性片部によりバランスよく支持されるので、釦部の傾きが抑制され、操作中の釦部の引っかかりを防ぐことが可能となる。
【０００５】
また、本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えるとともに、前記釦部側には、前記釦部から前記押圧方向に対して略垂直となる方向に突出したフランジ部分を有する構成を有している。この構成により、一対の弾性片部の釦側への接続箇所間の距離を広げることができるので、釦部の傾きをより安定して抑制することができるとともに、一対の弾性片部の長さを長くして弾性支持の設計の自由度を大きくすることができる。
【０００６】
また、本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えるとともに、前記弾性片部が、前記釦部側に一端側を接続されて前記釦部から前記釦部の押圧方向に伸びる第１アーム部分と、前記第１アーム部分より長くかつ前記第１アーム部分の他端側から前記第１アーム部分に対し略垂直な方向に伸びて他端側を前記支持壁に接続された第２アーム部分とを備えた構成を有している。この構成により、第１アーム部分と第２アーム部分とで釦部を安定して支持できるようになるとともに、釦部の操作ストローク長さの調整が容易にできるようになる。
【０００７】
また、本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えるとともに、前記弾性片部の前記釦部側への接続が、前記弾性片部の前記支持壁側とは反対方向へ向けて前記釦部の前記中心点からずれた位置でなされた構成を有している。この構成により、スイッチ操作装置をコンパクトに保ちながら弾性片部の長さを長く設定することが可能となる。
【０００８】
また、本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えるとともに、前記釦部が、前記釦部から前記押圧方向に略垂直な方向に突出されたフランジ部分を有し、前記フランジ部分が前記保持部に設けたガイド壁または前記基部に設けたガイド壁により前記釦部の押圧方向にガイドされるようにした構成を有している。この構成により、弾性片部による釦部の安定した支持に加え、保持部または基部のガイド壁による釦部の押圧方向のガイドで釦部のひっかかりをさらに確実に防ぐことができるようになる。
【０００９】
また、本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えるとともに、前記釦部が、前記釦部から前記押圧方向に略垂直な方向に突出されたフランジ部分を有し、前記フランジ部分が前記保持部に設けたガイド壁または前記基部に設けたガイド壁により前記釦部の押圧方向にガイドされるようにし、前記保持部に設けた前記ガイド壁により、前記基部を係止して前記基部の前記保持部に対する位置決めを行うようにした構成を有している。この構成により、釦部の傾き防止と基部の保持部に対する位置決めとの両方をガイド壁で行うことが可能となる。
【００１０】
また、本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えるとともに、前記弾性片部が、前記基部に当接することにより前記釦部の操作ストローク長さが制限されるようにした構成を有している。この構成により、釦部の操作ストローク長さを制限するに弾性片部を利用できることとなる。
【００１１】
また、本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えるとともに、前記釦部が、フランジ部分を有し、前記フランジ部分が前記基部に当接されることにより前記釦部の操作ストローク長さが制限されるようにした構成を有している。この構成により、釦部の操作ストローク長さを制限するのにフランジ部分を利用できることとなる。
【００１２】
また、本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えるとともに、前記釦部が、ストッパ脚を有し、前記ストッパ脚が前記保持部側に当接されることにより前記釦部の操作ストローク長さが制限されるようにした構成を有している。この構成により、確実に釦部の操作ストローク長さを制限して弾性片部の損壊を回避できることとなる。
【００１３】
また、本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えるとともに、前記釦部の前記基部側の面から前記押圧方向へ向かう部分を空間とした構成を有している。この構成により、スイッチ操作部の成型時の型抜きが可能となってスイッチ操作部を一体成型で作ることができるとともに、この空間にスイッチ側部品を配置することができることとなる。
【００１４】
また、本発明のスイッチ装置は、押圧面を有する釦部と、前記釦部の中心部から互いに長手方向の反対側に分かれて配置された一対の支持壁を有し前記釦部の前記釦部よりも押圧方向側に配置された基部と、前記釦部側に一端側が接続されて前記長手方向に伸び他端側が前記基部の前記支持壁に接続された一対の弾性片部とが一体に形成され、前記一対の弾性片部の一方が前記支持壁の一方に、また前記一対の弾性片部の他方が前記支持壁の他方にそれぞれ接続され、前記一対の弾性片部の前記釦部への接続箇所が前記釦部の略中心点を通り前記長手方向と平行な中心線の両側に分かれているスイッチ操作部を備え、かつ前記釦部が開口部分に進退可能に挿入され前記スイッチ操作部を有する前記基部が係止される保持部を備えるとともに、前記スイッチ操作部が複数個あり、かつ前記複数個のスイッチ操作部の前記基部同士がつながるようにして一体に形成された構成を有している。この構成により、複数個のスイッチ操作部を有するスイッチ装置を一体成型で製造することができ、また保持部への組み付けが１個１個行う必要がなくなるその作業が容易になる。
【００１５】
【発明の実施の形態】
以下、本発明の実施の形態について、図面を用いて説明する。図１は本発明の実施の形態のスイッチ装置１の要部の拡大側面図、図２は同スイッチ装置１の平面図、図３は同スイッチ装置１の下面図、図４は図２および図３の矢印ＩＶ方向からみた側方断面図である。
【００１６】
図１から図３に示すように、本発明の実施の形態のスイッチ装置１は、同じ構造とした複数のスイッチ操作部１０、２０を有し、これらは一対の弾性片部１６、１７および一対の弾性片部２６、２７を介して基部３０にそれぞれ連結され、プラスティックで一体に形成してある。
基部３０は、長方形の筒状に形成され、この長手方向に伸びる両側の壁がこの壁に対し垂直方向に伸びた第１の支持壁３１、第２の支持壁３２、および第３の支持壁３３で区切られ、第１の支持壁３１と第２の支持壁３２との間に第１のスイッチ操作部１０が、また第２の支持壁３２と第３の支持壁３３との間に第２のスイッチ操作部２０が配置されるように構成してある。この基部３０は、フロントパネルなどの保持部４０に係止される。
【００１７】
すなわち、保持部４０の裏側には、２つの係止壁４１ａ、４１ｂ、第１の両ガイド壁４２ａ、４２ｂ、第２の両ガイド壁４３ａ、４３ｂ、第３の両ガイド壁４４ａ、４４ｂ、および第４の両ガイド壁４５ａ、４５ｂがそれぞれ形成される。そして、保持部４０の係止壁４１ａと係止壁４１ｂとに基部３０の第１の支持壁３１の外面が当接されることにより基部３０の長手方向の動きが規制されている。なお、図示を省略した基部３０の他端側も同様にして基部３０の長手方向の位置決めがなされている。
【００１８】
また保持部４０の第１の両ガイド壁４２ａ、４２ｂと第２の両ガイド壁４３ａ、４３ｂとが、基部３０の第１の支持壁３１と第２の支持壁３２との間で基部３０の両側壁の内面側にそれぞれ係止されるとともに、第３の両ガイド壁４４ａ、４４ｂと第４の両ガイド壁４５ａ、４５ｂとが、基部３０の第２の支持壁３２と第３の支持壁３３との間で基部３０の両側壁の内面側にそれぞれ係止されて、基部３０が保持部４０に係止される。
【００１９】
一方、第１のスイッチ操作部１０は、釦部１１を有しており、この釦部１１の内部には「１」という数字が記載された表示部１２が嵌めこまれ、押圧面上に上記数字の表示が見えるようにしてある。また、釦部１１の押圧面とは反対方向の端部には、押圧方向に対し直交する面上で互いに直角方向をなして４方向に突出する十字状のフランジ部分１３が設けられている。この釦部１１は、図４に示すように、保持部４０の開口部分４０Ａに進退可能に挿入され、フランジ部分１３が保持部４０の裏面に当接することにより釦部１１が保持部４０から抜け出さないようにしてある。
【００２０】
このフランジ部分１３の長手方向の部分は、第１の両ガイド壁４２ａ、４２ｂ間、および第２の両ガイド壁４３ａ、４３ｂ間に位置して、フランジ部分１３の長手方向の部分の両側面が上記４つのガイド壁４２ａ、４２ｂ、４３ａ、４３ｂに沿って釦部１１の押圧方向にガイドされるようになっている。
なお、フランジ部分１３の長手方向の部分には、押圧方向に向けて伸ばされた２本のストッパ脚１４、１５が一体に形成されている。また、釦部１１から押圧方向に向かう部分は空間が形成され、図示しないスイッチの操作棒が入れられる。
【００２１】
また、フランジ部分１３の押圧方向側の面には、一対の弾性片部１６、１７の一端側が接続されるとともに、これらの一対の弾性片部１６、１７の他端側が基部３０の支持壁３１、３２にそれぞれ接続されるようにされてこれらが一体成型されている。弾性片部１６のフランジ部分１３への接続はフランジ部分１３および釦部１１の中心点５１より第２の支持壁３２側へ寄った位置で、また弾性片部１７のフランジ部分１３への接続は、フランジ部分１３および釦部１１の中心点５１より第１の支持壁３１側へ寄った位置でそれぞれなされている。
【００２２】
また、一対の弾性片部１６、１７は、釦部１１の中心点５１と第２のスイッチ操作部２０の釦部２２の中心点５２とを結ぶ中心線６０の両側に分かれた位置でフランジ部分１３に接続され、ここから基部３０の長手方向に伸びる両側壁上を互いに反対方向にある第１の支持壁３１、第２の支持壁３２へそれぞれ向かって伸びている。なお、中心線６０は、基部３０の長手方向に沿う線に平行となっている。
【００２３】
ここで第１の両弾性片部１６、１７は、側面からみてＬ字状に形成されている。すなわち、弾性片部１６は、図４に示すように、フランジ部分１３に一端側が接続されフランジ部分１３から押圧方向に伸びた第１アーム部分１６１と、これより長く設定され第１アーム部分１６１の押圧方向側の端部から垂直方向に折り曲げられて伸び基部４０の第１の支持壁３１に接続されている第２アーム部分１６２とを有している。また弾性片部１７も、弾性片部１６と同様の形状をしており、第１アーム部分と第２アーム部分を有するが、第２アーム部分が基部４０の第２の支持壁３２に接続されている。
【００２４】
一方、第２のスイッチ操作部２０も、第１のスイッチ操作部１０と同様の構造を有し、基部３０の長手方向に沿って第１のスイッチ操作部１０の隣に設けられている。なお、理解しやすくするため、図２では釦部２１とそのフランジ部分２３の一部を切り欠いて描いてある。また図１にその側面を拡大して示してある。
【００２５】
第２のスイッチ操作部２０は、釦部２１を有しており、この釦部２１の内部には「２」という数字が記載された表示部２２が嵌めこまれている。また、釦部２１には、この端部から十字状に突出するフランジ部分２３が設けられている。この釦部２１は、保持部４０の開口部分４０Ｂに挿入され、フランジ部分２３が保持部４０の裏面に当接させることで釦部２１が保持部４０から抜け出さないようにしてある。また、このフランジ部分２３の長手方向の部分は、第２の両ガイド壁４３ａ、４３ｂ間、および第３の両ガイド壁４４ａ、４４ｂ間に位置して、フランジ部分２３の長手方向の部分の両側面がそれらのガイド壁４３ａ、４３ｂ、４４ａ、４４ｂに沿って釦部２１の押圧方向にガイドされるように構成されている。
【００２６】
なお、フランジ部分２３の長手方向の部分には、押圧方向に向けて伸ばされた２本のストッパ脚２４、２５が一体に形成されている。また、釦部２１から押圧方向に向かう部分は空間が形成され、図示しないスイッチの操作棒が入れられる点も第１のスイッチ操作部１０と同じである。
【００２７】
フランジ部分２３の押圧方向側の面と基部３０の支持壁３１、３２との間には、それぞれ逆方向に向けられた一対の弾性片部２６、２７が接続されるようにされて、これらが一体成型されている。弾性片部２６は、フランジ部分２３および釦部２１の中心点５２より第２の支持壁３２側へ寄った位置でフランジ部分２３へ、また弾性片部１７は、フランジ部分１３および釦部２１の中心点５２より第１の支持壁３１側へ寄った位置でフランジ部分２３へそれぞれ接続されている。
【００２８】
また、一対の弾性片部２６、２７は、釦部２１の中心点５２を通る中心線６０に対し両側に分かれた位置、すなわち図２に示す断面部分２６ａと断面部分２７ａの位置でフランジ部分２３に接続されており、ここから基部３０の長手方向に伸びる両側壁上で互いに反対方向にある第２の支持壁３２、第３の支持壁３３へそれぞれ向かって伸ばされている。
【００２９】
ここで第２の両弾性片部２６、２７は、側面からみてＬ字状に形成されている。すなわち、弾性片部２６は、フランジ部分２３から押圧方向に伸びる第１アーム部分２６１と、これより長く設定され第１アーム部分２６１から垂直方向へ伸び基部４０の第２の支持壁３２に接続される第２アーム部分２６２とを有している。また弾性片部２７も、弾性片部２６と同様の形状をしており、第１アーム部分と第２アーム部分を有するが、第２アーム部分が基部４０の第３の支持壁３３に接続されている。
【００３０】
次に、上記スイッチ装置１の作動につき説明する。
操作者が第１のスイッチ操作部１０を操作すべく釦部１１を押圧すると、釦部１１が第１、第２の弾性片部１６、１７を弾性変形しながら押し込まれていく。このとき、第１、第２の弾性片部１６、１７のフランジ部分１３への接続箇所が、釦部１１の中心点５１の反対側にあり、かつ第１、第２の弾性片部１６、１７の基部３０への接続箇所が釦部１１の互いに反対側となる第１の支持壁３１と第２の支持壁３２であるので、フランジ部分１３に第１、第２の弾性片部１６、１７から作用する弾性反力は対抗しあって安定し、釦部１１が傾くのを抑制し、ひっかかりが生じないようにする。
【００３１】
また、上記釦部１１の押し込み中、釦部１１のフランジ部分１３の長手方向部分の側面が保持部４０の第１の両ガイド壁４２ａ、４２ｂ、および第２の両ガイド壁４３ａ、４３ｂの内面に沿ってガイドされるので、釦部１１が傾くのを抑制し、ひっかかりが生じないようになる。
このように釦部１１は安定して押し込まれていき、図示しないスイッチの接点を導通させる。なお、スイッチを作用させる位置を越えて釦部１１が押し込まれた場合、一対の弾性片部１６、１７が基部３０の両側壁上に位置しているので、これらの第２アーム部分の第１アーム部分側端部が基部３０に当接して釦部１１の操作ストローク長さを制限するスットパ機能を発揮する。
【００３２】
この場合、一対の弾性片部１６、１７が基部３０に当接しているにもかかわらず、さらに無理な力で釦部１１が押し込まれても、フランジ部分１３に設けた両ストッパ脚１４、１５が保持部４０側に当接して釦部１１のさらなる押し込みを阻止し、一対の弾性片部１６、１７を破損から守るように働く。釦部１１への押圧力を解除すれば、一対の弾性片部１６、１７の弾性復元力で釦部１１は、元の位置に戻る。この戻りにあっても、一対の弾性片部１６、１７による安定低した復元力とフランジ部分１３の保持部４０の第１の両ガイド壁４２ａ、４２ｂ、および第２の両ガイド壁４３ａ、４３ｂによるガイドとで、釦部１１の傾きが抑制され釦部１１のひっかかりが防止される。
【００３３】
以上のように、本発明の実施の形態のスイッチ装置は、釦部１１、２１のフランジ部分１３、２３にこの中心点５１、５２に対し反対側となる位置で一対の弾性片部１６と１７、２６と２７の一端側を接続するとともに、それらの他端側を釦部１１、２１の両側に分けて配置した一対の支持壁３１と３２、および一対の支持壁３２と３３にそれぞれ接続して相対する方向から釦部１１、２１を弾性支持するようにしたので、釦部１１、２１に作用する弾性力を互いに対抗させてバランスすることが可能となり、この結果釦部１１、２１の操作中における釦部１１、２１の傾きが抑制され、釦部１１、２１のひっかかりを防止することができる。この釦部１１、２１の傾きの抑制効果は、一対の弾性片部１６と１７、および一対の弾性片部２６と２７とが、釦部１１、２１から突出したフランジ部分１３、２３に接続されているので、これらの接続位置間距離が釦部１１、２１の幅よりさらに大きく離されることによりいっそうその効果を高めることが可能となる。また釦部１１、２１のひっかかりをなくすため組み立て時に実行されるクリアランス調整作業を不要とすることができる。なお、フランジ部分１３、２３は、釦部１１、２１が保持部４０の各開口部分４０Ａ、４０Ｂから釦部１１、２１が抜け出るのを防止する抜け止めとしても利用できる。
【００３４】
また、本発明の実施の形態のスイッチ装置１は、釦部１１、３１のフランジ部分１３、２３を保持部４０側の各ガイド壁４２ａ、４２ｂ、４３ａ、４３ｂ、４４ａ、４４ｂ、４５ａ、４５ｂに沿わせてガイドするようにしたので、釦部１１、２１の傾きをさらに抑制することが可能となる。この場合も、フランジ部分１３、２３が釦部１１、２１からさらに突出してガイドされる距離が離れるので、釦部１１、２１の傾きを抑制するのに効果的である。また、各ガイド壁４２ａ、４２ｂ、４３ａ、４３ｂ、４４ａ、４４ｂ、４５ａ、４５ｂは、両スイッチ操作部１０、２０を一体形成した基部３０を係止するのにも兼用でき、スイッチ装置１をコンパクトで安価なものとすることが可能となる。

各弾性片部１６、１７、２６、２７は、Ｌ字状に形成されているので、釦部１１、２１の押し込みにより第２アーム部分が大きく弾性変形しても第１アーム部分が弾性変形することにより釦部１１、２１を安定して保持できる。なお、各弾性片部１６、１７、２６、２７の第１アーム部分や第２アーム部分の長さ、幅、厚さ、材質等のいずれかを変更することで、各釦部１１、２１のストローク長さの調整など、各スイッチ操作装置にあったチューニングが容易にできることとなる。また、各弾性片部１６、１７、２６、２７を基部３０の両側壁の上に設けているので、各弾性片部１６、１７、２６、２７を基部３０に当接させることにより、釦部１１、２１の操作ストローク長さを規制するストッパとしても機能させることができる。この場合、ストッパ機能が働いたときにも弾性片部１６、１７、２６、２７が弾性変形可能なので、ソフトなストッパとして良好なストッパフィーリングが得られる。なお、フランジ部分１３、２３に複数のストッパ脚１４、１５、２４、２５を設けて、これらを弾性片部１６、１７、２６、２７のストッパ開始位置よりさらに釦部１１、２１を押し込んだところで保持部３０側に当接させて確実に、釦部１１、２１の操作ストロークを停止させるようにしたので、弾性片部１６、１７、２６、２７の過度の変形による損壊を防ぐことが可能となる。また、釦部１１、２１の裏側部分に空間を設けるようにしたので、スイッチ操作部１０、２０および基部３０を一体成型する際の型抜きが可能となり、スイッチ装置１の組立て時にはこの空間にスイッチまたはスイッチ側の部品を配置することができるようになる。
【００３６】
なお、上記実施の形態では釦部１１のフランジ部分１３を押圧方向にガイドするガイド壁を基部３０が係止される保持部４０の壁と兼用した場合について説明したが、本発明は、基部を係止する壁とは別にしたガイド壁を保持部４０に形成してもよいし、またはガイド壁を基部３０側に設けるようにしてもよい。また、釦部１１の操作ストローク長さの制限には、釦部１１のフランジ部分１３を基部３０に当接させて実行するようにしても同様の効果が得られる。また、弾性片部１６、１７、２６、２７の第１アーム部分と第２アーム部分は、上記実施の形態と若干異なる方向にそれぞれ傾けても同様の効果が得られるものである。
【００３７】
【発明の効果】
以上説明したように、本発明は釦部側にこの中心点に対し反対側となる位置で一対の弾性片部の一端側を接続するとともに、それらの他端側を釦部の両側に分けて配置した一対の支持壁にそれぞれ接続して相対する方向から釦部を弾性支持することにより、釦部を操作中でもその傾きを抑制するように安定して支持でき、操作中の釦部のひっかかりを防ぐことができるというすぐれた効果を有するスイッチ装置を提供することができるものである。

Thus, the button portions 11 and 21 can be stably held. In addition, by changing any of the length, width, thickness, material, etc. of the first arm portion and the second arm portion of each elastic piece portion 16, 17, 26, 27, each button portion 11, 21 Tuning suitable for each switch operating device, such as adjustment of the stroke length, can be easily performed. In addition, since the respective elastic pieces 16, 17, 26, 27 are provided on both side walls of the base 30, the respective elastic pieces 16, 17, 26, 27 are brought into contact with the base 30, whereby the button section is formed. It can also function as a stopper that regulates the operation stroke length of 11, 21. In this case, since the elastic pieces 16, 17, 26, and 27 can be elastically deformed even when the stopper function works, a good stopper feeling can be obtained as a soft stopper. A plurality of stopper legs 14, 15, 24, 25 are provided on the flange portions 13, 23, and when the button portions 11, 21 are further pushed in from the stopper start positions of the elastic pieces 16, 17, 26, 27. Since the operation strokes of the button portions 11 and 21 are surely stopped by being brought into contact with the holding portion 30 side, it is possible to prevent the elastic pieces 16, 17, 26 and 27 from being damaged by excessive deformation. Become. In addition, since a space is provided on the back side of the button portions 11 and 21, it is possible to remove the die when the switch operation portions 10, 20 and the base 30 are integrally molded. When the switch device 1 is assembled, a switch is provided in this space. Alternatively, components on the switch side can be arranged.
[0036]
In the above-described embodiment, a case has been described in which the guide wall that guides the flange portion 13 of the button portion 11 in the pressing direction is also used as the wall of the holding portion 40 to which the base 30 is locked. A guide wall separate from the wall to be locked may be formed on the holding portion 40, or the guide wall may be provided on the base 30 side. In addition, the same effect can be obtained by limiting the operation stroke length of the button portion 11 by causing the flange portion 13 of the button portion 11 to be in contact with the base portion 30. The same effect can be obtained even if the first arm portion and the second arm portion of the elastic pieces 16, 17, 26, 27 are inclined in directions slightly different from those in the above-described embodiment.
[0037]
