本発明は、その一環として、上記往復ポンプにおける復帰用のスプリングを、簡便かつ強力な合成樹脂製の板ばねとするとともに、その操作の感触をソフトで腰の強いものにしようとするものである。
【０００４】
【課題を解決するための手段】
上記目的達成のため、請求項１の発明は、噴出器本体１の内部に該トリガー３で作動される往復ポンプ４を内蔵して成るトリガー式液体噴出器において、上記噴出器本体１の上面に付設した水平基板12の前部両側から複数条の彎曲細片32,33 で形成した左右一対のばね片29を垂設し、これらのばね片29の下端30をそれぞれ上記トリガー３の両側面中途部へ機械的に連繋させ、また、その水平基板12の中途部から左右一対の軸受34を垂設し、該軸受34に上記トリガー３の上端部35を枢着したことを特徴とする。
【０００５】
【発明の実施の形態】
図面は、請求項１のトリガー式液体噴出器に係る実施の形態を示している。
図において、１は、側面形状が逆Ｌ字状の噴出器本体、２は、該噴出器本体の先端に設けた噴霧、噴射、噴泡に切換え得るノズル、３は、噴出器本体の前部から前後動可能に垂設したトリガー、４は、該トリガーでプランジャ５が作動される噴出器本体内蔵の往復ポンプ、６は、噴出器本体の上面乃至トリガーの外側に装着した復帰ばねで、トリガー及び往復ポンプのプランジャを前方へと付勢している。７は、噴出器本体の下端に回転自在に装着した内ねじ螺筒の装着筒、８は、該装着筒の内側で噴出器本体の下端から垂設した吸上げパイプ、９は、噴出器本体の外側に被着したカバーであり、これらは合成樹脂による成形部材から成る。
【０００６】
噴出器本体１は、合成樹脂成形の便宜上から上部の射出筒10の前端に筒先部材11を嵌着し、該筒先部材の先端に上記ノズル２を装着している。
噴出器本体１の上面の前部と後部すなわち上記筒先部材11の上面と上記射出筒10の後部上面に、合成樹脂製板ばねから成る上記復帰ばね６の水平基板12を受ける受座13,14 を形成しており、前部の受座13を上記筒先部材11の上面に一体に付設した小幅の水平片15から形成し、後部の受座14をその水平片15の幅よりも広い間隔で平行する２条の前後方向の突条16から形成している。
【０００７】
復帰ばね６は、合成樹脂製板ばねに係るものであり、上記前後の受座13,14 に架設する水平基板12を設けて、該水平基板の前部と後部を各々前後の受座13,14 へと着座させ、そして、水平基板12は、頂壁17の両縁からリブ18,19 を垂設したものとして、前端部を前部の受座13すなわち小幅の水平片15に対応する小幅に、それ以外を後部の受座14すなわち２条の突条16間に対応する広幅に形成して、その頂壁17の前部と後部をそれぞれ上記水平片15と２条の突条16に載置させるとともに、両側のリブ18,19 をそれぞれその水平片15と２条の突条16の外側へ嵌合させている。また、水平基板12の後部では、頂壁17の下面にて上記両縁のリブ19の内側に更に２条のリブ20を並設してそれぞれ上記２条の突条16の内側へ嵌合させている。
【０００８】
前後の受座13,14 と水平基板12との間には、それぞれ嵌合固定手段21,22 を講じており、前部の嵌合固定手段21は、水平基板前端部両縁のリブ18の前部内縁にそれぞれ係合爪23を設けて、両係合爪23を上記水平片15の両縁へ抱着係合させ、かつ、水平基板頂壁17の前部に第１の窓孔24を穿設するとともに、その水平片15の上面適所に第１の係止爪25を突設して、該第１の係止爪25をその第１の窓孔24の前縁に係合させて成る。また、後部の嵌合固定手段22は、その後部の受座14の後端にて噴出器本体１すなわち上記射出筒10の上面から前方へ抑止片26を突設して、該抑止片26により水平基板頂壁17の後端部をおさえ、かつ、該抑止片26に第２の窓孔27を穿設するとともに、水平基板頂壁17の後端部の上面適所に第２の係止爪28を突設して、該第２の係止爪28をその第２の窓孔27の前縁に係合させて成る。
【０００９】
水平基板12の前部両側からは、左右一対のばね片29を垂設してそれぞれ下端30をトリガー３の両側面中途部に設けたポケット31へ機械的に出入摺動自在に嵌挿連繋させており、左右一対のばね片29は、それぞれ平行乃至ほぼ平行させた２条の彎曲細片32,33 から形成し、下端30で一つにしている。また、水平基板12の左右一対のばね片29の直後からは左右一対のＣ字状片から成る軸受34を一体に垂設し、該軸受にトリガー３の二又状の両上端部35をこれらに突設させた片持軸36にて枢着することで前後動可能に垂設している。
【００１０】
而して、復帰ばね６の水平基板12を噴出器本体１上面の前部と後部すなわち筒先部材11の上面と射出筒10の後部上面に組み付けるときは、まず、復帰ばね６の水平基板12の後部を、その噴出器本体１の前方やや斜め上から後部の嵌合固定手段22たる抑止片26の下へ差し込んで、水平基板頂壁17後端部の第２の係止爪28をその抑止片26の第２の窓孔27の前縁へ係合させるとともに、射出筒10上面の後部の受座14すなわち２条の突条16へと着座させ、次いで、その水平基板12を押し下げて、水平基板12の前部を、筒先部材11上面の前部の受座13すなわち水平片15に着座させると同時に、前部の嵌合固定手段21たる水平基板前端部両縁のリブ18の各係合爪23をその水平片15の両縁へ抱着係合させ、かつ、水平基板頂壁17前部の第１の窓孔24の前縁をその水平片15上面の第１の係止爪25へと係合させる。
軸受34へのトリガー３の枢着及びばね片下端30のポケット31への係合は、その後に行えばよい。
なお、組み付けの手順はこれに限るものではなく、それらが前後してもよいことは勿論である。
【００１１】
このように組み付けられた復帰ばね６の水平基板12は、トリガー３が引かれることにより両ばね片29から後方及び上方へ大きな力を受けることとなるが、噴出器本体１の上面に安定かつ強力に定着されて、両ばね片29の反力板として機能し、両ばね片29に適確かつ強力に弾発力を発揮させる。したがって、両ばね片29には、合成樹脂製ではあってもトリガー３及び往復ポンプ４のプランジャ５に対し前方へと遜色なく適正に弾発付勢させることができる。そして、両ばね片29をそれぞれ２条の彎曲細片32,33 としているので、トリガー操作にソフトな感触を与えることができ、腰の強い弾力を持たせることができる。
また、第１及び第２の窓孔24,27 の各前縁に対する第１及び第２の係止爪25,28 の係合は、その水平基板12の前方への無用な移動や抜け出しを適確に阻止する。
【００１２】
【発明の効果】
本発明によれば、噴出器本体１の上面に付設した水平基板12の前部両側から複数条の彎曲細片32,33 で形成した左右一対のばね片29を垂設し、これらのばね片29の下端30をそれぞれトリガー３の両側面中途部へ機械的に連繋させているので、簡便かつ強力な合成樹脂製の板ばねとすることができるとともに、その操作の感触をソフトで腰の強いものにすることができて、使用感を頗る良好にでき、しかも、適正かつ確実な動作を得ることができ、金属製のコイルスプリングに勝るとも劣らないものとすることができる。
また、その水平基板12の中途部から左右一対の軸受34を垂設して、該軸受34にトリガー３の上端部35を枢着しているので、トリガーの枢着を簡潔かつ容易にすることができる。
