Description

【０００１】
【発明の属する技術分野】
本発明は、発火石を使用しヤスリ車の回転によって火花を飛ばすようにしたライターの着火機構に関し、特に、横車が空転して着火不能な状態を有する機構に関するものである。
【０００２】
【従来の技術】
従来より、横車をヤスリ車と分離して空転可能に設置し、単なる横車の回転操作ではヤスリ車が回転せず、着火不能として不用意に炎が発生しないようにした着火機構が種々提案されている。
【０００３】
例えば、第１の先行例として、米国特許第５,０９６,４１４号に示されるように、ヤスリ車が両側の支軸により回転自在に支持され、このヤスリ車の両側に支軸を中心として空回りする横車が設けられ、指を横車と共にヤスリ車の外周に接触させて、直接ヤスリ車を回転させることで着火するようにし、横車の回転だけでは着火不能とした構造が提案されている。
【０００４】
また、第２の先行例として、米国特許第５,５４７,３７０号に示されるように、ヤスリ車を回転可能に支持する支軸におけるヤスリ車の両側の横車を支持する部分を断面多角形状とし、この多角形状より大きい多角形穴を横車に設け、通常は横車が空転し、横車を押さえ付けることにより両多角形の角が係合してヤスリ車を回転可能とした構造が提案されている。
【０００５】
第３の先行例として、米国特許第５,８６８,５６１号に示されるように、ヤスリ車の支軸の断面を凹凸形状を有する構造とし、横車の中心孔は、この支軸の凹凸形状と相似でサイズの大きい形状として空転および係合可能に設け、第２の先行例と同じく通常は空回りする横車が、押さえ付けることにより支軸と係合しヤスリ車を回転可能とした構造が提案されている。
【０００６】
第４の先行例として、米国特許第５,９１３,６７４号に示されるように、ヤスリ車の支軸の断面を歯車形状、セレーション形状に設け、横車の中心孔を内径の大きい歯車形状、セレーション形状として空転および係合可能に設け、第２の先行例と同じく通常は空回りする横車が、押さえ付けることにより支軸と係合しヤスリ車を回転可能とした構造が提案されている。
【０００７】
第５の先行例として、米国特許第５,９７１,７４９号に示されるように、ヤスリ車は丸棒状の支軸により回転可能に支持され、ヤスリ車の両側の横車は支軸より径の大きい軸受穴で回転可能に支持されると共に、ヤスリ車の両側面には多角形穴を開口させ、横車の内側面には多角形穴よりサイズの小さい多角形突起を設けて空転および係合可能とし、通常は空回りする横車が、押さえ付けることによりヤスリ車と係合してヤスリ車を回転可能とした構造が提案されている。
【０００８】
一方、横車が空転可能ではないが、他の着火機構を示す第６の先行例として、米国特許第５,７５９,０２３号に示されるように、ヤスリ車の両側に横車を一体に回転可能に設けると共に、この横車とヤスリ車との間に滑り車を配設し、指の小さい子供などでは両側の横車への指の接触および滑り車の押し付けが十分に得られずに、着火操作を困難とした構造が提案されている。
【０００９】
【発明が解決しようとする課題】
しかして、上記のような先行例のライターの着火機構では、その使用態様または組み付けにおいて次のような問題を有し、実用化に向けて一層の改善が望まれる。
【００１０】
具体的には、第１の先行例では、ヤスリ車に直接触れてこれを回転させるので手が汚れる点で問題があり、また使用者によっては指肉が薄くヤスリ車に届かなければ回転できず正規の着火操作が行いにくい難点がある。また、第２ないし第５の先行例では、ヤスリ車の支軸と横車またはヤスリ車と横車との間のサイズの異なる形状の押し付け係合により横車とヤスリ車が一体に回転する構造であるが、通常の空転状態では係合しない寸法設定であるので、横車の支持にはその移動を許容するための隙間があって、がたつきが大きく組み付けが不安定であり、不良品と思われる恐れがあり商品性が低い。また、一般にヤスリ車、支軸、横車は、強度、耐熱性の面から金属が使用されるもので、金属同士の係合においては摩擦抵抗力が比較的小さいため、この第２ないし第５の先行例では、多角形状等がしっかり係合しない限り回転抵抗が比較的大きいヤスリ車の回転は難しく、正規の着火操作が行いにくく、また係合しやすい形状とすると空転しにくく所期の機能が得にくい難点がある。さらに、空転時に金属同士が衝突して異音が発生し、製品としての印象を損ねる難点もある。
【００１１】
一方、第６の先行例の滑り車のように、金属同士の押し付けに伴う摩擦抵抗力の増大だけではヤスリ車の回転抵抗力以上の力を得るのが難しく、また、滑り車の介在により着火操作性が低くなる難点があり、１回の操作では着火できないような扱いにくいライターとなる恐れがある。
【００１２】
本発明はこの点に鑑み、横車の空転状態の確保と着火操作性に優れると共に、横車のがたつきが少なく組み付けが良好で異音のない商品性の高いライターの着火機構を提供せんとするものである。
【００１３】
【課題を解決するための手段】
上記課題を解決した本発明のライターの着火機構は、ヤスリ車に発火石が圧接され、該ヤスリ車の回転により火花を発生させるライターの着火機構において、ライター本体に回転自在に支持された支点部材と、該支点部材と一体に回転可能なヤスリ車と、該ヤスリ車の両側における支点部材の外周に配設されたリング状の摩擦抵抗部材と、該摩擦抵抗部材の外周に空転可能に配設された横車とを備え、前記横車を中心方向に押し付けて摩擦抵抗部材の摩擦抵抗力を増大した状態での横車の回転操作により摩擦抵抗部材を介してヤスリ車を回転させることを特徴とするものである。
【００１４】
前記支点部材は、ヤスリ車の中心部に対して両側から嵌合固着される嵌合部を有し、該嵌合部に隣接して外周に前記摩擦抵抗部材が装着される伝達軸部を有するものが好ましい。前記支点部材は円盤状フランジ部を有し、該フランジ部とヤスリ車の側面との間に摩擦抵抗部材および横車を配設するのが好適である。前記支点部材は円盤状フランジ部を有し、該フランジ部を横車の外側面に形成されたフランジ部の外径より大きい凹部に挿入するのが好適である。
【００１５】
前記支点部材の摩擦抵抗部材と接触する面を、ローレット等の凹凸形状に設けてもよい。前記横車の摩擦抵抗部材と接触する面を、ローレット等の凹凸形状に設けてもよい。前記横車は、テーパー面で摩擦抵抗部材と接触するようにしてもよい。
【００１６】
前記摩擦抵抗部材は、ゴム、軟質樹脂などの弾性材料で構成するのが好ましい。前記摩擦抵抗部材は、Ｏリング状または平リング状に形成し得る。
【００１７】
【発明の効果】
以上のような本発明によれば、ライター本体に回転自在に支持された支点部材と一体に回転可能に設けたヤスリ車の両側における支点部材の外周にリング状の摩擦抵抗部材を配設し、該摩擦抵抗部材の外周に空転可能に横車を配設し、横車を中心方向に押し付けて摩擦抵抗部材の摩擦抵抗力を増大した状態での横車の回転操作により摩擦抵抗部材を介してヤスリ車を回転させるようにしたことにより、従来の着火操作のように横車を単に回転させようとしても横車は空回りしてヤスリ車は回転せず着火不能であり、所期の機能が得られる。また、着火のための操作は横車の押し回し操作であって、この横車によるヤスリ車の回転を摩擦抵抗部材の摩擦抵抗力を介して行うので、従来の係合形状による回転伝達と異なり、係合位置に制限がなく横車の押し付けによりヤスリ車を回転できるため、操作性が向上する。
【００１８】
また、横車を押し付けない空転状態にあっても摩擦抵抗部材の介在により、横車と支点部材およびヤスリ車にがたつきが少なく組み付けが安定する。また、横車の空転時には係合部分の衝突による異音発生がなく、スムーズに回転し不良品と思われることなく商品性が向上する。さらに、着火機構の組み立ては簡易に行え、量産性に適したものである。
【００１９】
【発明の実施の形態】
以下、図面を参照して本発明のライターの着火機構の実施の形態を詳細に説明する。図１は一つの実施の形態の着火機構を有するガスライターの中央縦断正面図、図２は組立状態の着火機構の斜視図、図３はその分解斜視図、図４は着火機構部分の中央縦断面図、図５は操作状態の着火機構の中央縦断面図である。
【００２０】
ガスライター１は、燃料ガスが貯蔵されたライター本体２と、燃料ガスを噴出するノズル３およびバルブ機構４１を有する燃料供給手段４と、この燃料供給手段４のノズル３を引き上げてバルブ機構４１の開閉作動を行う作動レバー５と、フリント式の着火機構６とを備えている。
【００２１】
ライター本体２は、合成樹脂で成形された有底筒状のタンク本体２１の上面に上蓋２２が気密に固定されて、その内部にブタンガス等の燃料ガスが貯蔵されるタンク部分が構成されると共に、このタンク部分とは別体にその上部に中間ケース２３が嵌着されてなる。
【００２２】
上記ライター本体２の上蓋２２には、貯蔵された燃料ガスの噴出量を制御する公知のバルブ機構４１による燃料供給手段４が配設され、該バルブ機構４１の中心に設けられたノズル３が中間ケース２３より上部に突出している。このノズル３には、前記作動レバー５の一端部に形成されたノズル係合部５１が係合される。また、上記ノズル３の上方周囲にはキャップ８が装着され、さらに、ノズル３からのガス噴出量を調整する炎長調整リング４２が設置されている。
【００２３】
着火機構６は、両端部の支点部材６１，６１と、該支点部材６１，６１に固着支持される周面がヤスリ面に形成されたヤスリ車６２と、該ヤスリ車６２の両側に空転可能に配設され外周面に凹凸形状を有する横車６３，６３と、横車６３，６３の内周側で支点部材６１，６１の外周に介装される摩擦抵抗部材６４，６４と、上記ヤスリ車６２の底部周面に石押しスプリング６７で付勢されて圧接する発火石６８（フリント）とからなる。発火石６８および石押しスプリング６７は前記中間ケース２３の筒部２４に収容されている。
【００２４】
両側の支点部材６１は、それぞれ円盤状のフランジ部６１ａの内側面中心に外周面に軸方向に延びる凹凸ローレットが形成された軸状嵌合部６１ｂが突設され、軸状嵌合部６１ｂとフランジ部６１ａとの間に周面が平坦な伝達軸部６１ｃが設けられ、フランジ部６１ａの外側面中心には回転軸６１ｄが突設されている。両側支点部材６１の軸状嵌合部６１ｂが、円筒状のヤスリ車６２の中心孔６２ａに両側から嵌合されて一体に回転するように結合される。外方に突出する両側の回転軸６１ｄが、前記中間ケース２３の左右両側に上方に指向して配設した支柱２５に開口された軸受孔２６（図４参照）に挿入支持され、ヤスリ車６２が回転可能に設けられている。そして、上記ヤスリ車６２を回転することにより発火石６８を擦過して火花が発生する。
【００２５】
前記摩擦抵抗部材６４は、断面円形のＯリング状で、ゴム、軟質樹脂などで構成され、表面は摩擦係数がある程度大きく形成されている。その内径は前記支点部材６１の伝達軸部６１ｃの外径に相当し、自由状態または若干伸ばした状態で伝達軸部６１ｃの外周に装着される。
【００２６】
前記横車６３は、リング状で外周が指掛け用の凹凸形状に設けられ、内周開口の周面が前記摩擦抵抗部材６４の外周に接触可能な当接面６３ａに形成され、この当接面６３ａの内径は摩擦抵抗部材６４の外径と略一致する。横車６３の内側面は平坦に、外側面には前記支点部材６１のフランジ部６１ａの外径より大きく、厚みに相当する深さの円形凹部６３ｂが設けられている。組付状態においては、該凹部６３ｂ内にフランジ部６１ａが挿入され、横車６３の半径方向の移動が許容されると共に移動範囲が規制される。つまり、フランジ部６１ａの外周面が凹部６３ｂの周面に当接する範囲で横車６３が半径方向に移動可能である。その際、当接面６３ａが摩擦抵抗部材６４に接触し、横車６３の移動量に応じて変形させる。摩擦抵抗部材６４が押圧されると、横車６３の当接面６３ａおよび支点部材６１の伝達軸部６１ｃに圧接して摩擦抵抗力が増し、横車６３の回転を支点部材６１およびヤスリ車６２に伝達し、一体に回転するようになっている。
【００２７】
なお、ヤスリ車６２に支点部材６１を嵌合する際に、前記摩擦抵抗部材６４および横車６３が、支点部材６１のフランジ部６１ａとヤスリ車６２の側面との間の伝達軸部６１ｃの外周に同時に組み付けられる。
【００２８】
前記作動レバー５は、支柱２５の間を通りライター本体２の中間ケース２３上に前後方向に延びて配設されている。該作動レバー５は合成樹脂からなり、一端にノズル３の先端が挿通しノズル首部が係合するスリット溝によるノズル係合部５１が形成され、他端の上面に押圧部５２が形成されている。上記ノズル係合部５１は、常時ノズルに係合している。なお、前記ノズル係合部５１と押圧部５２との中間部分には前記筒部２４の上端が挿通し、発火石６８がヤスリ車６２の底部外周に圧接する。
【００２９】
以上のような構成からなるガスライター１について、その作用を詳細に説明する。まず、図１および図４に示す非使用状態において、摩擦抵抗部材６４は全周において非押圧状態にあり、横車６３はその中心位置が支点部材６１の中心位置と略一致する。この状態で横車６３の外周に指が掛けられ、単に回転操作または弱い押し付け力で回転操作された際には、摩擦抵抗部材６４はその外周部の横車６３の当接面６３ａに対する摩擦抵抗力または内周部の支点部材６１の伝達軸部６１ｃに対する摩擦抵抗力が小さく、また、ヤスリ面に発火石６８が圧接していることでヤスリ車６２の回転にはある程度大きな抵抗があり、横車６３は支点部材６１に対して空転する。その際、摩擦抵抗部材６４は回転せず外周部で横車６３に対し滑動するか、横車６３と共に回転して内周部で支点部材６１に対して滑動するか、内外周の両方で滑動する。この横車６３の空転により、支点部材６１およびヤスリ車６２は回転しないで火花は発生せず、作動レバー５が押し下げられてガスが噴出しても着火しない。
【００３０】
次に、ガスライター１の着火操作は、図５に示すように、横車６３の外周の凹凸に指Ｆを当て中心方向に強い力で押し付けると共に回転させるのに続いて作動レバー５の押圧部５２を押し下げる。横車６３の中心方向への押し付けに伴い、この押し付け部分の摩擦抵抗部材６４は圧縮されて横車６３の中心位置が移動する。図５の状態では、支点部材６１のフランジ部６１ａの外周部が、横車６３の凹部６３ｂの外周壁に接触する程度まで、横車６３の押し付けが行われている。
【００３１】
この状態では、摩擦抵抗部材６４の内外周における横車６３の当接面６３ａおよび支点部材６１の伝達軸部６１ｃに対する密着が強まり、摩擦抵抗力がヤスリ車６２と発火石６８の擦過抵抗力より増大し、横車６３の回転力が摩擦抵抗部材６４を介して支点部材６１に伝達され、また摩擦抵抗部材６４の側面がヤスリ車６２の側面に圧接する場合にはヤスリ車６２にも直接伝達されて、横車６３の回転に伴ってヤスリ車６２が回転し火花が発生する。作動レバー５の揺動によりノズル係合部５１はノズル３を上昇させて燃料ガスを噴出させ、前記火花により着火する。
【００３２】
なお、前記横車６３の回転操作から指Ｆが離れて作動レバー５の押圧部５２に移行する途中で、横車６３の押し付け力が弱まり、ヤスリ車６２への回転力の伝達が遮断されるが、ヤスリ車６２の初期の回転量によって着火に必要な火花は確保できる。
【００３３】
消火のために作動レバー５の押圧部５２から指Ｆを離すと、燃料供給手段４内に配設したスプリングの戻り力によりノズル３が下降し、燃料ガスの噴出が停止される。また、前記横車６３から指Ｆが離れることで、摩擦抵抗部材６４の押圧が解放されて復元し、横車６３は空転状態に戻る。
【００３４】
本実施形態によれば、横車６３の通常回転操作では横車６３が空転して火花が発生せず、従来操作では着火不能であることが認識でき、また、着火操作としては従来の操作に横車６３の押し付け動作を加えたことにより、一連の操作に連係して操作性に優れている。ヤスリ車６２の外周に触れることなく手も汚れない。空転時には摩擦抵抗部材６４がゴム、軟質樹脂等によるリング状であることで、異音の発生がなく、摩擦抵抗部材６４が全周で均等な厚みに復元して各部に形成される隙間は小さく横車６３のがたつきも少ない。
【００３５】
図６は、他の形態の摩擦抵抗部材を示す斜視図である。この摩擦抵抗部材６５は、ゴム、軟質樹脂などで断面が矩形の平リング形状に設けられている。該摩擦抵抗部材６５は、外周面および内周面が平坦であることで、支点部材６１および横車６３に対する接触面積が広くなり、弱い押し付け力での摩擦抵抗力の増大が得られる。また、弾性変形量の少ない（剛性の大きい）素材による摩擦抵抗部材６５の形態に適している。
【００３６】
その他、摩擦抵抗部材としては断面形状が、半円形状、楕円形状、台形状、太鼓型などに適宜設計変更可能である。また、材質としては、剛性の大きさに応じ軟らかいものと硬いものとで押し付け力に対する変形程度が異なって摩擦抵抗力が異なり、また、素材自体の摩擦係数の違いによっても摩擦抵抗力が異なり、弱い押し付け時の横車６３の空転を確保すると共に、適度な押し付け力が加わると急激に摩擦抵抗力が増大してヤスリ車６２の回転が行えるように、材質、形状等を選定するものである。
【００３７】
次に、図７は、他の形態の支点部材６１および横車６３を示す斜視図である。この形態の支点部材６１の伝達軸部６１ｅは、外周面が軸方向に延びる凹凸形状によるローレットに設けられている。また、横車６３の内周当接面６３ｃは、同様に軸方向に延びる凹凸形状によるローレットに設けられている。なお、本形態においては、平リング状の摩擦抵抗部材６５を採用するのが好適である。
【００３８】
上記ローレットとしたことにより、摩擦抵抗部材６５として硬いものが使用された際に、横車６３の押し付け時に伝達軸部６１ｅおよび当接面６３ｃのローレットの凸部先端が摩擦抵抗部材６５に食い込んで摩擦抵抗力が増し、横車６３の回転力の伝達を確保している。なお、伝達軸部６１ｅおよび当接面６３ｃの一方のみローレットとしてもよく、その凹凸形状の高さも変更可能である。また、上記伝達軸部６１ｅおよび当接面６３ｃの摩擦抵抗力の増大構造としては、ローレットのほか、表面を粗面化する形態が適宜採用可能であり、摩擦抵抗部材６５の材質、硬さ、形態に応じて設計される。
【００３９】
次に図８〜図１０は、それぞれ他の形態の横車６３を有する着火機構６を示す断面図であり、テーパー面で抵抗部材６４と接触するようにしている。
【００４０】
図８の横車６３の当接面６３ｄは、内側のヤスリ車６２の側面に向けて内径が大きくなるように広がるテーパー面（円錐面）に形成されている。この形態では、横車６３が中心方向に押し付けられた際には、上記テーパー面による当接面６３ｄでＯリング状の摩擦抵抗部材６４が圧縮されて、支点部材６１の伝達軸部６１ｃに対して押圧されると共に、内側のヤスリ車６２の側面に対しても押圧されて回転力を伝達する摩擦抵抗力が確保される。
【００４１】
図９の横車６３の当接面６３ｅは、中央部の内径が大きくなるようにＶ溝状のテーパー面に形成されている。この形態では、横車６３が中心方向に押し付けられた際には、上記Ｖ溝面による当接面６３ｅでＯリング状の摩擦抵抗部材６４が圧縮されて、当接面６３ｅと摩擦抵抗部材６４との接触面積が大きくなり、回転力を伝達する摩擦抵抗力が確保される。
【００４２】
図１０の横車６３の当接面６３ｆは、中央部の内径が小さくなるようにＶ凸状のテーパー面に形成されている。この形態では、横車６３が中心方向に押し付けられた際には、山形面による当接面６３ｆでＯリング状の摩擦抵抗部材６４の中央部が圧縮されて、支点部材６１の伝達軸部６１ｃに対して押圧されると共に、両側のヤスリ車６２の側面およびフランジ部６１ａの側面に対しても押圧されて回転力を伝達する摩擦抵抗力が確保される。
【００４３】
なお、上記横車６３の内周当接面の形状としては、そのほか、円弧状凹面、円弧状凸面、周方向に延びる縦溝を有する面などに形成可能で、それぞれの形態に応じた伝達特性が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to an ignition mechanism for a lighter that uses spark stones to cause a spark to fly by rotation of a file wheel, and more particularly to a mechanism in which a side wheel is idle and cannot be ignited.
[0002]
[Prior art]
Various types of ignition mechanisms have been proposed so that the horizontal vehicle can be separated from the file wheel so that it can idle, and the simple rotation operation of the horizontal vehicle prevents the file wheel from rotating and prevents inadvertent flames. Has been.
[0003]
For example, as a first prior example, as shown in US Pat. No. 5,096,414, a file wheel is rotatably supported by support shafts on both sides, and idles around the support shaft on both sides of the file wheel. A structure has been proposed in which a horizontal vehicle is provided, the finger is brought into contact with the outer periphery of the file wheel together with the horizontal vehicle, and the file wheel is directly rotated to ignite, and the ignition is impossible only by the rotation of the horizontal vehicle. .
[0004]
As a second prior example, as shown in U.S. Pat. No. 5,547,370, a portion for supporting a horizontal vehicle on both sides of a file wheel on a support shaft for rotatably supporting a file wheel has a polygonal cross section. A polygonal hole larger than this polygonal shape is provided in the horizontal vehicle, and the horizontal vehicle usually idles, and by pressing the horizontal vehicle, the corners of both polygons are engaged so that the file wheel can rotate. Proposed.
[0005]
As a third preceding example, as shown in US Pat. No. 5,868,561, the cross section of the support shaft of the file car has a structure having an uneven shape, and the center hole of the side wheel has an uneven shape of this support shaft. As in the second preceding example, a side wheel that normally rotates idly engages with a support shaft and presses a file wheel so that the file wheel can rotate. Proposed.
[0006]
As a fourth preceding example, as shown in U.S. Pat.No. 5,913,674, the cross section of the support shaft of the file wheel is provided in a gear shape and a serration shape, and the center hole of the side wheel is formed in a gear shape having a large inner diameter. As a serration shape, a structure has been proposed that is provided so as to be able to idle and engage, and in the same manner as in the second preceding example, a side wheel that normally rotates idly engages with a support shaft by pressing down so that the file wheel can rotate.
[0007]
As a fifth preceding example, as shown in U.S. Pat. No. 5,971,749, the file wheel is rotatably supported by a round bar-shaped support shaft, and the side wheels on both sides of the file wheel are smaller in diameter than the support shaft. It is supported rotatably by a large bearing hole, and a polygonal hole is opened on both sides of the file wheel, and a polygonal protrusion smaller in size than the polygonal hole is provided on the inner surface of the horizontal wheel, and is idled and engaged. A structure has been proposed in which a horizontal vehicle that normally rotates can be engaged with a file wheel by pressing down to rotate the file wheel.
[0008]
On the other hand, the horizontal vehicle is not capable of idling, but as a sixth preceding example showing another ignition mechanism, as shown in US Pat. No. 5,759,023, the horizontal vehicle is integrally rotated on both sides of the file car. In addition to providing it as possible, a slipping wheel is arranged between this side car and the file car, and for children with small fingers etc., finger contact with the side car on both sides and pushing of the sliding car are not sufficiently obtained, A structure that makes ignition operation difficult has been proposed.
[0009]
[Problems to be solved by the invention]
Thus, the lighter ignition mechanism of the prior example as described above has the following problems in its use mode or assembly, and further improvement is desired for practical use.
[0010]
Specifically, in the first preceding example, there is a problem in that the hand gets dirty because it touches and rotates the file car directly, and some users cannot rotate unless the finger meat reaches the file car thinly. There is a difficulty in performing regular ignition operation. Further, in the second to fifth preceding examples, a structure in which the side wheel and the file wheel rotate integrally by the pressing engagement of the shape of the file shaft and the side wheel or the different shape between the file wheel and the side wheel. However, since the dimensions are set so that they do not engage in the normal idling state, there is a gap in the support of the side car to allow its movement, the backlash is large, the assembly is unstable, and the defective product The merchantability is low. In general, the file wheel, the support shaft, and the side wheel are made of metal from the viewpoint of strength and heat resistance, and the friction resistance is relatively small in the engagement between the metals. In the preceding example, it is difficult to rotate the file wheel, which has a relatively large rotational resistance unless the polygonal shape etc. are firmly engaged, and it is difficult to perform regular ignition operation. There is a difficulty that can not be obtained. Furthermore, there is a problem that the metal collides with each other at the time of idling and noise is generated, which impairs the impression as a product.
[0011]
On the other hand, as in the sixth preceding example, it is difficult to obtain a force that exceeds the rotational resistance of the file wheel only by increasing the frictional resistance force due to the pressing between the metals. There is a drawback that the operability is lowered, and there is a fear that it becomes a difficult to handle lighter that cannot be ignited by one operation.
[0012]
In view of this point, the present invention does not provide a lighter ignition mechanism that is excellent in securing the idling state of the horizontal vehicle and igniting operability, and has a low level of rattling of the horizontal vehicle and good assembly and no abnormal noise. It is what.
[0013]

The ignition stone 68 and the stone pushing spring 67 are accommodated in the cylindrical portion 24 of the intermediate case 23.
[0024]
The fulcrum members 61 on both sides are each provided with a shaft-like fitting portion 61b formed with an uneven knurl extending in the axial direction on the outer peripheral surface at the center of the inner surface of the disc-shaped flange portion 61a. A transmission shaft portion 61c having a flat peripheral surface is provided between the flange portion 61a and a rotation shaft 61d protruding from the center of the outer surface of the flange portion 61a. The shaft-like fitting portion 61b of the both-side fulcrum member 61 is fitted to the center hole 62a of the cylindrical file wheel 62 from both sides so as to rotate together. The rotating shafts 61d on both sides projecting outward are inserted and supported in bearing holes 26 (see FIG. 4) opened in the support columns 25 arranged upwardly on the left and right sides of the intermediate case 23, and the file wheel 62.

The inner diameter corresponds to the outer diameter of the transmission shaft portion 61c of the fulcrum member 61, and is mounted on the outer periphery of the transmission shaft portion 61c in a free state or a slightly extended state.
[0026]
The horizontal wheel 63 has a ring shape and the outer periphery is provided with an irregular shape for hooking, and the peripheral surface of the inner peripheral opening is formed on a contact surface 63a that can contact the outer periphery of the frictional resistance member 64. The inner diameter of 63 a is substantially the same as the outer diameter of the frictional resistance member 64. The lateral surface of the horizontal wheel 63 is flat, and the outer surface is provided with a circular recess 63b that is larger than the outer diameter of the flange portion 61a of the fulcrum member 61 and has a depth corresponding to the thickness. In the assembled state, the flange portion 61a is inserted into the concave portion 63b, and the movement of the side wheel 63 in the radial direction is allowed and the movement range is restricted. That is, the side wheel 63 can move in the radial direction within a range in which the outer peripheral surface of the flange portion 61a contacts the peripheral surface of the concave portion 63b. At that time, the contact surface 63 a comes into contact with the frictional resistance member 64 and is deformed according to the amount of movement of the side wheel 63. When the frictional resistance member 64 is pressed, the frictional resistance is increased by being pressed against the contact surface 63a of the side wheel 63 and the transmission shaft 61c of the fulcrum member 61, and the rotation of the side wheel 63 causes the fulcrum member 61 and the file wheel 62 to rotate. It is designed to rotate as a unit.
[0027]
Note that when the fulcrum member 61 is fitted to the file wheel 62, the friction resistance member 64 and the side wheel 63 have an outer periphery of the transmission shaft portion 61c between the flange portion 61a of the fulcrum member 61 and the side surface of the file wheel 62.

[0028]
The actuating lever 5 extends between the columns 25 and extends on the intermediate case 23 of the lighter body 2 in the front-rear direction. The actuating lever 5 is made of synthetic resin, and has a nozzle engaging portion 51 formed by a slit groove through which the tip of the nozzle 3 is inserted and engaged with the nozzle neck portion at one end, and a pressing portion 52 is formed at the upper surface of the other end. . The nozzle engaging portion 51 is always engaged with the nozzle. The upper end of the cylindrical portion 24 is inserted into an intermediate portion between the nozzle engaging portion 51 and the pressing portion 52, and the ignition stone 68 is pressed against the outer periphery of the bottom portion of the file wheel 62.
[0029]
The operation of the gas lighter 1 having the above configuration will be described in detail. First, in the non-use state shown in FIGS. 1 and 4, the frictional resistance member 64 is in a non-pressed state on the entire circumference, and the center position of the side wheel 63 substantially coincides with the center position of the fulcrum member 61. In this state, when a finger is put on the outer periphery of the side wheel 63 and is simply rotated or operated with a weak pressing force, the friction resistance member 64 has a friction resistance against the contact surface 63a of the side wheel 63 on the outer periphery. The friction resistance force against the transmission shaft portion 61c of the fulcrum member 61 at the inner peripheral portion is small, and since the ignition stone 68 is pressed against the file surface, there is a certain amount of resistance to the rotation of the file wheel 62. The vehicle 63 idles with respect to the fulcrum member 61. At that time, the frictional resistance member 64 does not rotate and slides with respect to the side wheel 63 at the outer periphery, or rotates with the side wheel 63 and slides with respect to the fulcrum member 61 at the inner periphery, or slides on both the inner and outer periphery. To do. Due to the idling of the side wheel 63, the fulcrum member 61 and the file wheel 62 do not rotate and no spark is generated, and even if the operating lever 5 is pushed down and gas is ejected, no ignition occurs.
[0030]
Next, as shown in FIG. 5, the ignition operation of the gas lighter 1 is performed by pressing the finger F against the unevenness on the outer periphery of the side wheel 63 and pressing it with a strong force in the central direction and rotating it. Press 52 down. As the side wheel 63 is pressed toward the center, the frictional resistance member 64 at the pressed portion is compressed and the center position of the side wheel 63 moves. In the state of FIG. 5, the side wheel 63 is pressed to the extent that the outer peripheral portion of the flange portion 61 a of the fulcrum member 61 contacts the outer peripheral wall of the concave portion 63 b of the side wheel 63.
[0031]
In this state, the contact between the contact surface 63a of the lateral wheel 63 and the transmission shaft 61c of the fulcrum member 61 on the inner and outer circumferences of the friction resistance member 64 is increased, and the friction resistance is greater than the friction resistance of the file wheel 62 and the ignition stone 68. The rotational force of the side wheel 63 is transmitted to the fulcrum member 61 via the frictional resistance member 64, and when the side surface of the frictional resistance member 64 is pressed against the side surface of the file wheel 62, it is directly transmitted to the file wheel 62. Then, the file wheel 62 rotates with the rotation of the side wheel 63, and a spark is generated. The nozzle engaging portion 51 raises the nozzle 3 by ejecting the operating lever 5 to eject the fuel gas, and is ignited by the spark.
[0032]
It should be noted that the pressing force of the side wheel 63 is weakened and the transmission of the rotational force to the file wheel 62 is interrupted while the finger F moves away from the rotation operation of the side wheel 63 and shifts to the pressing portion 52 of the operating lever 5. However, the spark required for ignition can be secured by the initial rotation amount of the file wheel 62.
[0033]
When the finger F is released from the pressing portion 52 of the operating lever 5 for extinguishing the fire, the nozzle 3 is lowered by the return force of the spring disposed in the fuel supply means 4, and the ejection of the fuel gas is stopped. Further, when the finger F is separated from the side wheel 63, the pressure of the frictional resistance member 64 is released and restored, and the side wheel 63 returns to the idling state.
[0034]
According to the present embodiment, it can be recognized that the horizontal wheel 63 is idling in the normal rotation operation of the horizontal wheel 63 and no spark is generated, and that it is impossible to ignite in the conventional operation, and the conventional operation is used as the ignition operation. By adding the pressing operation of the side wheel 63, the operability is excellent in cooperation with a series of operations. The hand does not get dirty without touching the outer periphery of the file wheel 62. Since the frictional resistance member 64 is in a ring shape made of rubber, soft resin or the like during idling, no abnormal noise is generated, and the frictional resistance member 64 is restored to a uniform thickness over the entire circumference so that the gaps formed in each part are small. There is little shakiness of the side car 63.
[0035]
FIG. 6 is a perspective view showing another form of the frictional resistance member. The friction resistance member 65 is made of rubber, soft resin or the like and is provided in a flat ring shape having a rectangular cross section. Since the frictional resistance member 65 has a flat outer peripheral surface and inner peripheral surface, the contact area with the fulcrum member 61 and the side wheel 63 is widened, and an increase in the frictional resistance force with a weak pressing force can be obtained. Moreover, it is suitable for the form of the frictional resistance member 65 made of a material having a small amount of elastic deformation (high rigidity).
[0036]
In addition, the cross-sectional shape of the frictional resistance member can be appropriately changed to a semicircular shape, an elliptical shape, a trapezoidal shape, a drum shape, or the like. In addition, as a material, the soft and hard materials have different degrees of deformation with respect to the pressing force depending on the stiffness, the friction resistance force is different, and the friction resistance force is also different depending on the difference in the friction coefficient of the material itself, The material, shape, and the like are selected so that the horizontal wheel 63 can be idly rotated during weak pressing, and the frictional resistance can be suddenly increased to rotate the file wheel 62 when an appropriate pressing force is applied. .
[0037]
Next, FIG. 7 is a perspective view showing a fulcrum member 61 and a side wheel 63 of another form. The transmission shaft portion 61e of the fulcrum member 61 of this form is provided on a knurled shape having a concavo-convex shape whose outer peripheral surface extends in the axial direction. Moreover, the inner peripheral contact surface 63c of the horizontal wheel 63 is provided in a knurled shape having a concave and convex shape that similarly extends in the axial direction. In the present embodiment, it is preferable to employ a flat ring-shaped frictional resistance member 65.
[0038]
By using the knurling, when a hard material is used as the frictional resistance member 65, the tip of the knurls of the transmission shaft 61e and the contact surface 63c bite into the frictional resistance member 65 when the side wheel 63 is pressed. The frictional resistance is increased and transmission of the rotational force of the side wheel 63 is ensured. Only one of the transmission shaft portion 61e and the contact surface 63c may be a knurl, and the height of the concavo-convex shape can be changed. Further, as the structure for increasing the frictional resistance force of the transmission shaft portion 61e and the contact surface 63c, a form in which the surface is roughened can be appropriately adopted in addition to the knurling. The material, hardness, Designed according to the form.
[0039]

[0040]
The contact surface 63d of the horizontal wheel 63 in FIG. 8 is formed as a tapered surface (conical surface) that widens toward the side surface of the inner file wheel 62 so that the inner diameter increases. In this embodiment, when the side wheel 63 is pressed in the center direction, the O-ring-shaped frictional resistance member 64 is compressed by the contact surface 63d formed by the tapered surface, and the transmission shaft portion 61c of the fulcrum member 61 is compressed. And a frictional resistance force that is also pressed against the side surface of the inner file wheel 62 to transmit the rotational force.
[0041]
The contact surface 63e of the horizontal wheel 63 in FIG. 9 is formed in a V-groove tapered surface so that the inner diameter of the central portion is increased. In this embodiment, when the horizontal wheel 63 is pressed in the center direction, the O-ring-shaped frictional resistance member 64 is compressed by the contact surface 63e formed by the V groove surface, and the contact surface 63e and the frictional resistance member 64 are compressed. And the frictional resistance for transmitting the rotational force is ensured.
[0042]
The contact surface 63f of the horizontal wheel 63 in FIG. 10 is formed as a V-convex tapered surface so that the inner diameter of the central portion is reduced. In this embodiment, when the horizontal wheel 63 is pressed in the center direction, the central portion of the O-ring-shaped frictional resistance member 64 is compressed by the contact surface 63f formed by the chevron, and the transmission shaft portion 61c of the fulcrum member 61 is compressed. And a frictional resistance force that transmits the rotational force by being pressed against the side surfaces of the file wheel 62 and the side surface of the flange portion 61a on both sides.
