Description

【考案の詳細な説明】 「産業上の利用分野」 本考案はジョイステイツクに関する。
「従来技術及びその課題」 従来のジョイステイツクは、例えば実開昭55−17379号
のように操作棒を中心位置に自動復帰させるために一組
の可変抵抗器それぞれの回転軸にトーションバネを係合
させた、いわゆる２軸トーションバネ構造が用いられて
いる。しかしながらこのような２軸トーションバネ構造
のジョイステイツクは操作棒の保持力が２つのトーショ
ンバネそれぞれの弾発力によって決まるので、第３図に
示すように操作棒の傾斜角及び傾斜方向によって保持力
が異なり操作性が極めて悪く、また傾斜角が小さいほど
保持力が小さくなる、すなわち操作棒の復元力が小さく
なるために操作棒の中心位置へ復帰する精度が悪かっ
た。
前記従来例に対し、本願出願人は実開昭63−188906号に
よって、操作棒がその下端部に１本のコイルバネを介さ
れて伸縮でき、縦断面形状がほぼＶ字状で操作棒最下端
部位がその内壁傾斜面を圧接摺動するガイドケースを備
えた一軸圧縮コイルバネ構造のジョイステイックを開示
した。
この一軸圧縮コイルバネ構造のジョイステイツクは操作
棒下端部に介されたコイルバネの弾発力によって操作棒
を中心位置に自動復帰させ、しかも１本のコイルバネに
よって操作棒の保持力が決まるので操作棒の傾斜方向に
依らず同心円上の保持力を均一にできるものではある
が、ガイドケースの内壁を単にカップ形状としただけで
あるため、操作棒の傾斜角に依ってその保持力が変化し
てしまい、操作をする感触が微妙に変化するという課題
を有していた。
本考案の目的は、一軸圧縮コイルバネ構造のジョイステ
イツクを更に操作性の良い、しかも操作棒の中心位置へ
の復帰精度が良いジョイステイツクとするために、操作
棒の保持力がその傾斜方向及び傾斜角に依らず常に均一
なジョイステイツクを提供することである。
「課題を解決するための手段」 上記課題を解決するために本考案は、少なくとも操作棒
１と、前記操作棒１の下端部で該操作棒１と同軸のコイ
ルバネ３に付勢された移動ピース４と、前記操作棒１の
中立状態で前記移動ピース４の先端部が最低位置となる
カップ形状の内壁12を有するガイドケース７とから構成
され、前記操作棒１を傾けたとき前記移動ピース４の先
端部が前記内壁12の曲面を圧接摺動するジョイステイツ
クにおいて、前記操作棒１の中立状態からの傾斜角をθ
としたとき、前記内壁12の曲面と前記コイルバネ３の縮
みとの間に、前記縮みが前記傾斜角θの平方根に比例す
る関係を持たせる。
「作用」 上記のように本考案のジョイステイツクは構成されてい
るので、操作棒１の保持力Ｆは操作棒１の傾斜角θに依
らず一定となる。
「実施例」 第１図（ａ），（ｂ），（ｃ）及び第２図を用いて本考
案の一実施例を説明する。
第１図（ａ），（ｂ）は本考案の一実施例であるジョイ
ステイツクの断面図で、同図（ａ）は操作棒の中立状態
を示し、同図（ｂ）は操作棒を角度θ傾斜させた状態を
示す。また第１図（ｃ）は本実施例のジョイステイツク
の斜視図である。また第２図は本考案のジョイステイツ
クにおける操作棒の保持力を示すグラフである。
各図において同一部位には同一番号を付してあり、１は
操作棒、2a,2bはセンターシャフト、３はコイルバネ、
４は移動ピース、５は球面体、６はアウターケース、７
はガイドケース、8a,8bはエンコーダ、９はシャフトカ
バー、10は操作棒１をセンターシャフト2bに回動自在に
支承させるピン、11a,11bはセンターシャフト2a,2bの中
間部に開けられた操作棒１が各軸方向に嵌遊される穴、
12はガイドケース７の内壁である。
センターシャフト2a,2bは直交した状態でそれぞれアウ
ターケース６に軸回動自在に保持され、一端がアウター
ケース６の外でそれぞれエンコーダ8a,8bの回転軸とな
っている。そして操作棒１の傾斜方向及び傾斜角に応じ
てセンターシャフト2a,2bは回動される。センターシャ
フト2bにピン10で支承された操作棒１はその下端部の同
軸上にコイルバネ３を介した移動ピース４が取り付けら
れている。そしてコイルバネ３は移動ピース４先端部の
球面体５をアウターケース６に固定されたガイドケース
７の内壁12に圧接する。操作棒１は操作されないとき第
１図（ａ）のようにコイルバネ３が最も伸びた中心位置
を維持し、操作棒１が操作されたときは第１図（ｂ）の
ように内壁12に沿ってコイルバネ３が縮むので、操作棒
１から手を離すと操作棒１は中心位置へ自動復帰され
る。
ここで操作棒１を操作したときコイルバネ３は だけ縮むよう内壁12のカップ形状を規定したので、第２
図に示すように操作棒１の保持力は傾斜方向、傾斜角に
依らず全域で均一となることを次に示す。
ここで保持力Ｆを保持モーメントＭで考えると、保持モ
ーメントＭとコイルバネ３に蓄えられるエネルギーＥは となり、（１）式において保持力Ｆがθに無関係に一定
とすれば となる。またコイルバネ３に蓄えられるエネルギーＥは
コイルバネ３の縮み量をδとして となるので、（２）（３）式より が導かれる。
つまり、保持力Ｆを一定とするために、（４）式で表さ
れる様にコイルバネ３が縮めばよい。
従って、本考案によるジョイステイツクを操作すると操
作棒１がどのような傾斜方向及び傾斜角の状態において
も保持力Ｆが均一であるから操作性が極めて良く、操作
棒が精度良く中心位置へ復帰される。
なお、本実施例は本考案の一実施例に過ぎず、例えばエ
ンコーダ8a,8bの代わりにボリュームを用いること、球
面体５と移動ピース４を一体として移動ピース４の先端
部を球面状とすること、アウターケース６とガイドケー
ス７を一体にすること等は任意である。
「効果」 以上のように本考案のジョイステイツクは構成されてい
るので、操作棒の保持力は同一円周上だけでなくあらゆ

棒が中心位置へ精度良く復帰される。
