Description

【０００１】
【産業上の利用分野】
本発明は、罐本体の先端に設けたノズル材を罐本体方向に押圧するとノズル材に設けたノズルより前記罐本体内に収容した液体が噴霧状に噴出し、押圧操作を中止すると前記ノズルが自動的に閉じることができるようにしたスプレー罐のノズル開放装置に関するものである。スプレー罐は、罐本体に収容した液体の相違によって種々のものがあるが、本発明は、概し、塗料用スプレー罐に適用するものである。
【０００２】
【従来の技術】
罐本体を手先で保持して、ノズル材を指先でコントロールするようにして罐本体内の液体の噴出、中止を行っており、スプレー罐自体は、手先乃至指先の操作によってノズルの開放を行うような構造にもなってもいる。
【０００３】
本発明は、手先によるスプレー罐のノズルの開放操作を機械的操作に代えることのできる装置を提供すべく創案したものである。
【０００４】
【課題を解決するための手段】
装置基枠に復帰ばねの付勢に抗して移動手段によってスプレー罐ホルダーを先端部において移動自在に組付け、該スプレー罐ホルダーに着脱自在に組付けるスプレー罐のノズル材側を当接させる受圧片をスプレー罐ホルダーの前記先端部に、罐本体側を当接させる押圧片を操作片の後端部にそれぞれ設けると共に、前記操作片を前記スプレー罐ホルダーに該ホルダーの前記先端部方向にコイルばねによって移動するように付勢させて組付け、該操作片の先端部によって前記復帰ばねの付勢方向に相対する内面が押圧されて前記装置基枠に設けた案内片に沿って移動する制御片と前記案内片のそれぞれに、前記操作片の先端側に設けた押圧子が前記コイルばねの付勢によって圧接する摺接縁を前記スプレー罐ホルダーの移動方向に沿わせて設け、該摺接縁を突縁部と凹入縁部とで構成し、案内片側の摺接縁は前記押圧子の前記復帰ばねに抗して移動する始点と終点の両位置にのみ前記突縁部、他を凹入縁部とすると共に、制御片側の摺接縁は、前記復帰ばねの付勢に抗して該制御片が移動するときの前記押圧子が位置する側の一半を突縁部、他の一半部を凹入縁部とした、構成としたものである。
【０００５】
【作用】
スプレー罐ホルダーにノズル材を受圧片側に罐本体を押圧片側に配して両片で挟持させるようにスプレー罐を組付けると、押圧片を備えた操作片は、前記ホルダーにコイルばねによって該ホルダーの先端側方向すなわち受圧片方向に移動するように付勢されているから、押圧片はスプレー罐の罐本体を受圧片方向に常時押圧している状態にあって、該押圧（押圧片の移動）は、操作片の先端側に設けた押圧子が案内片に設けた摺接縁の突縁部に接触して規制され（このとき、制御片の摺接縁の凹入縁部位置にも前記押圧子は位置している）、従って、スプレー罐のノズルは開放しない状態にある。
【０００６】
この状態時に、復帰ばねの付勢に抗して移動手段によってスプレー罐ホルダーを移動させると、該スプレー罐ホルダーに組付けた操作片も同時にホルダーの移動方向に移動し、操作片の先端は前記復帰ばねの付勢に抗して制御片の相対する内面の一方を押圧し、これを移動させる。そして、この時に、案内片側の摺接縁の突縁部に接していた押圧子は凹入縁部位置に移動するが、同時に制御片側の摺接縁の凹入縁部から突縁部位置に移動するため、コイルばねの作用は規制され、操作片すなわち押圧片は当初の位置にあってノズルの開放操作は行われない。すなわち、制御片の移動時には操作片の先端が制御片を伴って移動することになるから往路時にあっては押圧子が当該制御片の摺接縁の突縁部に接触（圧接）した状態が維持され、コイルばねの付勢は押圧片側に現れることがない。
【０００７】
そして、制御片を移動死点位置まで移動させると、押圧子は案内片と制御片の摺接縁の互いに重なり合った各突縁部に接触する位置に位置することになり、かつ、両片の摺接縁の凹入縁部は互いに重なり合うように位置する。
【０００８】
この状態でスプレー罐ホルダーに対する外力の負荷を中止すると、復帰ばねの付勢によってスプレー罐を組付けたスプレー罐ホルダーは原位置方向へ復帰しようとし、それに伴って操作片も当該原位置方向へと移動するため、操作片の先端は制御片の前記相対する内面の他方を押圧し、該制御片を伴って移動することになり、かつ、このとき、押圧子は制御片および案内片の摺接縁の突縁部位置から凹入縁部位置にコイルばねの付勢によって係合することになり、案内片側の凹入縁の長さ分当該係合状態は継続される。そして、この係合状態中、コイルばねの付勢に操作片に設けた押圧片がスプレー罐の罐本体を押圧し、その外力をノズル材側の受圧片が受けることになるから、罐本体は移動し、ノズルの開放が行われ、本体内の液体が噴霧状になって噴出することになり、前記の通り、案内片側の凹入縁の長さ分すなわち、押圧子が該凹入縁に係合している時間分噴出操作が行われ、その長さは、コイルばねが強くなればなる程短かくすることができる。
【０００９】
そして、制御片が原位置に復帰すると（復帰ばねの作用が中止される）、押圧子は案内片の摺接縁の突縁部に再び乗り上がることになり、ノズルは閉塞されるのである。
【００１０】
【発明の実施の形態】
図面は本発明に係るスプレー罐のノズル開放装置の一実施形態を示し、図１は一部欠截正面図、図２は図１の一部欠截拡大図、図３は図２の平面図、図４は図３のｙ−ｙ線断面図、図５は押圧子と摺接縁の関係の断面図、図６はレール締結装置にマーカーを付した状態の平面図である。
【００１１】
図示のスプレー罐のノズル開放装置は、軌道レールを交替する際、旧レールの枕木締結装置を用いて新レールを枕木に締結する際、当該枕木締結装置の各構成材の相対的な位置関係を誤まりなく互いに組付けるために旧レールの締結状態時に予め該締結装置部分にマーカー（直線状の目印）を表示するために用いるマーカー表示器（従来例はない）に本発明を適用したものである。
【００１２】
実施形態のマーカー表示器Ａは、操作レバー１の操作によって塗料用スプレー罐１０を所定距離移動させ、その移動中に、塗料用スプレー罐１０の罐本体１０Ａを、該罐本体１０Ａの先端側に設けたノズル材１０Ｂ方向に押圧して移動させ、ノズル１０Ｂ´より塗料を噴出させ（スプレー罐は、通常、ノズル材側を移動させて噴出させる。）、締結装置Ｂ表面に線状のマーカー（塗料層）を施こすようにしたものであるが、本装置の適用は実施形態の表示器Ａに限る必要がないことは勿論である。
【００１３】
前記操作レバー１は支柱２の上端に中間部において支軸３８において回動自在に枢着したもので、この操作レバー１の回動操作によって該レバー１の先端に一端（上端）を止着した線体３に緊張（テンション）状態と該緊張状態後の弛緩状態が生じ、この結果、前記の通り、ノズル１０Ｂ´より塗料が噴出するようになっている。
【００１４】
支柱２は、表示器Ａの携帯時（移動時）や使用時における把手ともなるもので、径の大きい上部管２Ａに細い下部管２Ｂを嵌挿して伸縮自在と成し、上部管２Ａ側に設けた締付ねじ４の先端を下部管２Ｂに圧接することにより一定の長さに保持させるようにしたもので、下部管２Ｂの下端には前記締結装置Ｂのボルトの頭部ａに必要に応じて係合して位置決めとする、下面開口の係合片５を設けてある。
【００１５】
この支柱２の前記下部管２Ｂには、装置基枠６を片持ち梁状にして取付け、装置基枠６は、上部６´側を水平方向に配したへの字形の一対の基片６Ａ，６Ａの上端部と中間部および下端部のそれぞれの間にスペーサー６Ｂ，６Ｂ´，６Ｂ´を介在させ，これらを組付けボルト７と組付けナット８で互いに組付け、前記支柱２（下部管２Ｂ）を貫通させた上端部のスペーサ６Ｂの場合は、前記組付けボルト７と組付けナット８を前記支柱２を介する一側側に配し、スリット９を設けた他の一側側に配した組付けボルト７には前記組付けナット８に代る蝶ナット８Ａを螺合して構成したもので、蝶ナット８Ａを緩めることによって前記スリット９をわずかに開かせて支柱２に沿って移動させ、所定の位置において当該蝶ナット８Ａを締付けることによって定置させ、高さ位置を自在に調節できるようにしてある。
【００１６】
この装置基枠６の傾斜状の下部６´´側の下面側（支柱２の下端部側）には、スライドレール装置１２を介してスプレー罐ホルダー１１を該傾斜状の下部６´´に沿わせて縦動自在に組付けてある。
【００１７】
スプレー罐ホルダー１１は、前記スライドレール装置１２を介して前記装置基枠６に組付けたホルダー基板１３にホルダー筒１４の先端側を支持させるようにして連設し、このホルダー筒１４に挿脱可能に嵌挿した前記スプレー罐１０を、後端側（底面側）を押圧片１５で先端側を受圧片１６で挟持させるようにしてスプレー罐１０を保持するようにしたものである。
【００１８】
前記スライドレール装置１２は、装置基枠６の前記下部６´´側の一対のスペーサ６Ｂ´，６Ｂ´にわたして固定した雌レール片１２Ａとスプレー罐ホルダー１１側の前記ホルダー基板１３に止着した雄レール片１２Ｂ間に鋼球を転動自在に支持させた仲介片１２Ｃを介在させて構成し、鋼球の存在によって雌雄のレール片１２Ａ，１２Ｂは互いに自在に移動できるようにした公知のもので、雌レール片１２Ａの長手方向の一端側である下部と雄レール片１２Ｂの前記長手方向の他の一端側である上部のそれぞれに支杆１７，１７´を立設し、該支杆１７，１７´のそれぞれに復帰ばね（コイルスプリング）１８の端部を係止して両杆１７，１７´間に架設し、上側の支杆１７´には前記線体３の下端（先端）を接続したものである。
【００１９】
すなわち、このスライドレール装置１２は、操作レバー１を操作して線体３を引張ると（線体３にテンションをかけると）、装置基枠６に設けた雌レール片１２Ａ側が不動側となってスプレー罐ホルダー１１の雌レール片１２Ｂが移動側となって、復帰ばね１８の付勢に抗して移動し（上昇し）、操作レバー１による引張り操作を中止すると復帰ばね１８の付勢によって雄レール片１２Ｂ（スプレー罐ホルダー１１）は降下し、原位置に復帰するようにしたものである。
【００２０】
また、前記スプレー罐ホルダー１１は、管体で成る前記ノズル１０Ｂ´を着脱自在に取付けるようにした市販のスプレー罐１０を保持するようにしたもので、前記ホルダー基板１３に立設した前記受圧片１６にホルダー筒１４に嵌挿したスプレー罐１０のノズル材１０Ｂの先端面を当接させ、スプレー罐１０の後端面（底面）には前記押圧片１５を当接させるようにしてスプレー罐１０を保持させ、受圧片１６に設けた透孔を通じて前記ノズル材１０Ｂにノズル１０Ｂ´を嵌挿して組付けるようにしたものである。
【００２１】
スプレー罐１０の後端側を保持する押圧片１５は、Ｌ形片で成り、ホルダー筒１４の後端に該ホルダー筒１４に設けた切欠１９の開口端部に該一片１５ａを部分的に係合させるようにして他の一片１５ｂを蝶ボルト２０によって操作片２１の後端に止着したもので、操作片２１に伴ってホルダー筒１４（スプレー罐１０）の先端方向に移動し、スプレー罐１０の本体１０Ａを押圧するようにしてある。
【００２２】
なお、押圧片１５の一片１５ｂにホルダー筒１４の前記長手方向に沿って長い長孔３９を設けてあるのは、該押圧片１５とスプレー罐１０との位置関係を調節するためである。
【００２３】
押圧片１５を後端側に組付けた前記操作片２１は、中間部を前記ホルダー筒１４と該ホルダー筒１４にボルト締めした一対の保持片２２，２２´に保持され、ホルダー筒１４の長手方向に沿って移動自在に配したもので、保持片２２，２２´間の該操作片２１の中間部と操作片２１の先端側を保持する保持片２２のそれぞれに第二支杆２３，２３´間に張設したコイルばね２４によってスプレー罐ホルダー１１（ホルダー筒１４）の先端方向に移動するように付勢され、その付勢は、操作片２１の先端に設けた押圧子２５が前記装置基枠６側に設けた案内片２６と制御片２７の摺接縁２８，２９に圧接して規制される。
【００２４】
前記装置基枠６を構成する一方の基片６Ａには、取付部片２６ａと案内部片２６ｂより成る断面Ｌ字形の前記案内片２６を、取付部片２６ａにおいて板ばね３０と共にビス３１で止着し、この案内片２６の前記案内部片２６ｂと板ばね３０の立上り部片３０ｂとの間には、板ばね３０の先端部片３０ａで前記基片６ａ乃至取付部片２６ａ方向に軽く押え付けるようにして前記制御片２７を介在させて摺嵌して組付け、制御片２７を方形枠状にして設けた、前記基片６Ａ乃至規制片２６の長手方向に沿う方向に長い空隙３２に前記操作片２１の先端部２１Ａを遊嵌し、制御片２７は、操作片２１の先端部２１Ａによって前記空隙３２の長手方向に（スプレー間ホルダー１１の移動方向に）相対する内面３２´，３２´´を押圧されて、その押圧された方向（すなわち、基片６Ａの長手方向）に移動するようにしてある。
【００２５】
前記板ばね３０は互いに並行関係に配した取付部片３０ｃと先端部片３０ａとの間に前記立上り部片３０ｂを配して構成し、取付部片３０ｃを前記案内片２６の取付部片２６ａと重ね合わせて前記の通り、ビス３１によって基片６Ａに止着し、立上り部片３０ｂ部が規制片２６の案内部片２６ｂとで間隙を構成し、該間隙内に摺嵌した前記制御片２７を先端部片３０ａで軽く押え付けて、操作片２１の先端部２１Ａを介しての外力の負荷が中断した状態では制御片２７の当該状態位置を保持するものである。すなわち、制御片２７は板ばね３０が圧接することにより規制片２６の長手方向に沿う適宜の位置で定置する。
【００２６】
操作片２１の先端部２１Ａ側に設けた前記押圧子２５は実施形態ではローラで構成するが、これは騒音の発生防止と案内片２６や制御片２７の端縁で構成する摺接縁２８，２９に沿ってコイルばね２４の作用による圧接しながらの移動を円滑に行わせるためで、これらを無視すればローラ形式のものでなくとも差し支えはない。
【００２７】
また、押圧子２５は、操作片２１のホルダー筒１４側の片面、すなわち、前記押圧片１５がスプレー罐１０の底面を押圧している側の片面に配し、前記コイルばね２４の付勢によって、案内片２６側の摺接縁２８と制御片２７側の摺接縁２９の一方又は双方に常時圧接するように配されている。
【００２８】
案内片２６側の摺接縁２８は、前記復帰ばね１８の付勢に抗して移動する始点部（案内片２６の長手方向の一端）と終点部（案内片２６の長手方向の他の一端）を突縁（直縁）部２８ａ，２８ａ´とし、該突縁部２８ａ，２８ａ´間の中間部を凹入縁部２８ｂと成し、凹入縁部２８ｂに押圧子１５がコイルばね２４の付勢によって係合したときは、該押圧子１５を備えた操作片２１も押圧子１５が凹入縁部２８ｂに係合する方向すなわち操作片の後端から先端方向に移動し、押圧片１５がスプレー罐本体１０Ａを押圧するような関係にしてある。
【００２９】
制御片２７側の摺接縁２９は、該制御片２７の前記空隙３２に係合した駆動片先端部２１Ａの一端２１Ａ´が該空隙３２の一端（制御片２１の一方の内面）３２´に接触したときに前記押圧子２５が係合する位置関係にして一半側に凹入縁２９ｂを設け、他の一端２１Ａ´´が空隙３２の他の一端（制御片２１の他の一方の内面）３２´´に接触したときに前記押圧子２５が係合する位置関係にして前記凹入縁２９ｂに隣接する他の一半側に突縁部（直縁）２９ａを設けたものである。
【００３０】
すなわち、復帰ばね１８がスプレー罐ホルダー１１に作用していないときは、操作片先端部２１Ａは空隙３２の一端（一方の内面）３２´側にあって、この先端部２１Ａの位置関係によって制御片２７は案内片２６の一端側に偏した位置にあることになって、該制御片２７側の凹入縁部２９と案内片２６側の一方の突縁部２８ａが互いに重なり合う位置関係に存することになり、コイルばね２４の付勢による押圧子２５の、制御片２７側の凹入縁部２９ｂへの係合は案内片２６側の突縁部２８ａの存在によって阻止されることになるのである。このように、案内片２２と制御片２７の突縁部２８ａ，２８ａ´，２９ａに押圧子２５が接触する位置関係にあるときは凹入縁２８ｂ，２９ｂへの押圧子２５の係合が規制され、凹入縁２８ｂ，２９ｂが一致したときのみ、コイルばね２４の作用により操作片２１は前進し、押圧子２５が摺接縁２８，２９の凹入縁部２８ｂ，２９ｂに係合するようにしてある。
【００３１】
しかして、スプレー罐ホルダー１１にノズル材１０Ｂを受圧片１６側に罐本体１０Ａを押圧片１５側に配して両片１６，１５で挟持させるようにしてスプレー罐１０を組付けると、押圧片１５を備えた操作片２１は前記ホルダー１１にコイルばね２４によって該ホルダーの先端側方向すなわち前記受圧片１６方向に移動するように付勢されているから、押圧片１５はスプレー罐１０の罐本体１０Ａを受圧片１６方向に常時押圧している状態にあることになる。そして、該押圧（押圧片の移動）は、操作片２１の先端側に設けた押圧子２５が案内片２６に設けた摺接縁２８の突縁部２８ａに接触して規制され（このとき、制御片２７の摺接縁２９の凹入縁部２９ｂ位置にも前記押圧子２５は位置している）、従って、スプレー罐１０のノズルは開放しない状態にある。
【００３２】
このようにスプレー罐ホルダー１０を組付けた状態にして係合片５を締結装置Ｂのボルト頭部ａに係合するようにして位置決めして把手兼用の支柱２の上端部に組付けた操作レバー１を操作して線体３を復帰ばね１８の付勢に抗して引張ると、線体３の先端はスプレー罐ホルダー１１に接続してあるのでスライドレール装置１２の存在によって該ホルダー１１は装置基枠６の傾斜状の下部６´´に沿って移動、上昇することになる。
【００３３】
そしてこのスプレー罐ホルダー１１の移動（上昇）中、該スプレー罐ホルダー１１に組付けた（搭載した）操作片２１も同時にホルダーの移動方向に伴われて移動し、操作片２１の先端部２１Ａは前記復帰ばね１８の付勢に抗して空隙３２を一端（一方の内面）３２´側から他の一端（他の一方の内面）３２´´側に移動して制御片２７を押圧し、これを移動させる。そして、この時に、案内片２６側の摺接縁２８の一方の突縁部２８ａに接していた押圧子２５は凹入縁部２８ｂ位置に移動するが、同時に制御片２７側の摺接縁２９の凹入縁部２９ｂから突縁部２９ａ位置に移動するため、コイルばね２４の付勢作用は規制され、操作片２１すなわち押圧子２５はコイルばね２４が作用する方向においては当初の位置を維持する。すなわち、操作片２１のコイルばね２４の付勢に抗する移動時に伴う制御片２７の移動時には押圧子２５が当該制御片２７の摺接縁２９の突縁部２９ａに接触（圧接）した状態が維持され、コイルばね２４の付勢は押圧片１５側に現れることがない。
【００３４】
そして、制御片２７を移動死点位置まで移動させると、押圧子２５は案内片２６と制御片２７の摺接縁２８，２９の互いに重なり合った各突縁部２８ａ´，２９ａに接触する位置に位置することになり、かつ、両片２６，２７の摺接縁２８，２９の凹入縁部２８ｂ，２９ｂは互いに重なり合うように位置する（要するに、制御片２７の往路移動中は該制御片２７の突縁部２９ａに押圧子２５が接してコイルばね２４の付勢作用は規制される）。この状態で操作レバー１による線体３の引っ張り操作を中止すると、復帰ばね１８は自由状態となり、この復帰ばねの付勢によってスプレー罐１０を組付けた（搭載した）スプレー罐ホルダー１１は原位置方向へ復帰（降下）しようとし、それに伴って操作片２１も当該原位置方向へと移動するため、操作片２１の先端部２１Ａは制御片２１の空隙３２内を移動し、一端（片面）３２´´から他の一端（片面）３２´側へ移動してこれを押圧し、該制御片２７を押圧して（伴って）移動することになり、かつ、このとき、押圧子２５は制御片２７および案内片２６の摺接縁２８，２９の突縁部２８ａ´，２９ａ位置から凹入縁部２８ｂ，２９ｂ位置にコイルばね２４の付勢によって係合することになり、案内片２６側の凹入縁部２８ｂの長さ分当該係合状態は継続される。そして、この係合状態中、コイルばね２４の付勢によって操作片２１に設けた押圧片１５がスプレー罐１６の罐本体１０Ａを押圧し、その外力をノズル材１０Ｂ側の受圧片１６が受けることになるから、罐本体１０Ａは移動し、ノズルの開放が行われ、本体内の塗料（液体）が噴霧状になって噴出して、締結装置Ｂにマーカーｍが線状になって施される。なお、前記の通り、案内片２６側の凹入縁部２８ｂの長さ分すなわち、押圧子２５が該凹入縁部２８ｂに係合している時間分噴出操作が行われ、その時間的長さは、復帰ばね１８の強弱によって決まり、強いほど、時間的に短かくなりノズル１０Ｂ´から噴出して描くマーカーｍの線状がきれいに現われる。
【００３５】
そして、制御片２７が原位置に復帰する（復帰ばね１８の作用が中止される）と、押圧子２５は案内片２６の摺接縁２８の突縁部２８ａに再び乗り上がることになり、ノズルは閉塞されるのである。
【００３６】
なお、実施形態の制御片２７を省略したときは、押圧子２５が摺接縁２８の往復移動時に凹入縁部２８ｂ位置にある間、ノズルからの噴霧が行われることになる。
【００３７】
実施形態のように復帰ばね１８の弾性が作用するときだけ、噴霧操作を行うようにしたのは、復帰ばね１８の強弱によって一定の状態で噴霧が行われ、均一な操作を望むことができるからである。
【００３８】
【発明の効果】
本発明は前記の通りの構成であるから、機械的操作によってスプレー罐のノズルを確実に開放することができ、種々の分野に利用のできる装置を提供できる。

[Industrial application fields]
In the present invention, when the nozzle material provided at the tip of the heel body is pressed toward the heel body, the liquid contained in the heel body is sprayed out from the nozzle provided in the nozzle material, and when the pressing operation is stopped, the nozzle is The present invention relates to a nozzle opening device for a spray bottle that can be automatically closed. There are various types of spray bottles depending on the liquids contained in the bottle body, but the present invention is generally applied to a spray bottle for paint.
[0002]
[Prior art]
The main body is held by the hand and the nozzle material is controlled by the fingertip to eject and stop the liquid in the main body, and the spray bottle itself opens the nozzle by operating the hand or fingertip. It is also a good structure.
[0003]
The present invention was devised to provide a device that can replace the opening operation of the nozzle of the spray bottle by the hand with a mechanical operation.
[0004]
[Means for Solving the Problems]
A pressure receiving pressure is applied to the apparatus base frame so that the spray cup holder is movably assembled at the distal end portion by moving means against the bias of the return spring, and the nozzle material side of the spray bowl that is detachably assembled to the spray cup holder is contacted. A piece is provided at the tip of the spray bottle holder, and a pressing piece for contacting the bottle body side is provided at the rear end of the operation piece, and the operation piece is coiled on the spray bottle holder in the direction of the tip of the holder. Control that moves and moves along a guide piece provided on the device base frame by pressing the inner surface of the operation spring opposite to the biasing direction by the tip of the operation piece. Each of the piece and the guide piece is provided with a sliding contact edge along which the presser provided on the distal end side of the operation piece comes into pressure contact with the urging force of the coil spring along the moving direction of the spray cup holder. The sliding contact edge is constituted by a protruding edge portion and a recessed insertion edge portion, and the sliding contact edge on the guide piece side is the protruding edge portion only at both the start point and the end point that move against the return spring of the pressing element. The other side is a recessed edge, and the sliding contact edge on the control piece side is a protruding edge on the side where the pressing element is located when the control piece moves against the biasing force of the return spring. The other half is configured as a recessed edge.
[0005]
[Action]
When the spray bottle is assembled so that the nozzle material is placed on the spray pad holder on the pressure receiving piece side and the cup body is sandwiched between the two pieces, the operation piece provided with the press piece is attached to the holder by a coil spring. Since the pressing piece is urged so as to move in the tip side direction, that is, in the pressure receiving piece direction, the pressing piece is in a state of constantly pressing the spear body of the spray bottle in the pressure receiving piece direction. ) Is regulated by the pressing element provided on the distal end side of the operation piece coming into contact with the protruding edge portion of the sliding contact edge provided on the guide piece (at this time, the position of the recessed edge portion of the sliding contact edge of the control piece is also determined). Therefore, the spray nozzle is not opened.
[0006]
In this state, when the spray cup holder is moved by the moving means against the bias of the return spring, the operation piece assembled to the spray cup holder also moves in the moving direction of the holder, and the tip of the operation piece is One of the opposing inner surfaces of the control piece is pressed against the urging force of the return spring and moved. At this time, the pressing element that has been in contact with the protruding edge portion of the sliding contact edge on the guide piece side moves to the recessed edge position, but at the same time, from the recessed edge portion of the sliding contact edge on the control piece side to the protruding edge position. Therefore, the action of the coil spring is restricted, the operation piece, that is, the pressing piece is in the initial position, and the nozzle is not opened. That is, when the control piece is moved, the tip of the operation piece moves together with the control piece, so that the pressing element is in contact (pressure contact) with the protruding edge portion of the sliding contact edge of the control piece during the forward path. The bias of the coil spring does not appear on the pressing piece side.
[0007]
Then, when the control piece is moved to the moving dead center position, the presser is located at a position where the guide piece and the sliding contact edge of the control piece are in contact with each overlapping protruding edge portion, and The recessed edges of the sliding contact edge are positioned so as to overlap each other.
[0008]
If the external force applied to the spray cup holder is stopped in this state, the spray cup holder with the spray cup attached will return to the original position by urging the return spring, and the operation piece will also move to the original position accordingly. In order to move, the tip of the operation piece presses the other of the opposing inner surfaces of the control piece, and moves together with the control piece. At this time, the pressing element is in sliding contact with the control piece and the guide piece. The engagement is continued from the protruding edge position of the edge to the recessed edge position by the bias of the coil spring, and the engagement state is continued for the length of the recessed edge on the guide piece side. And during this engaged state, the pressing piece provided on the operating piece for biasing the coil spring presses the main body of the spray bottle, and the pressure receiving piece on the nozzle material side receives the external force.

Are connected.
[0019]
That is, in this slide rail device 12, when the operation lever 1 is operated to pull the wire body 3 (when the wire body 3 is tensioned), the female rail piece 12A provided on the device base frame 6 becomes the non-moving side. The female rail piece 12B of the spray cup holder 11 becomes the moving side and moves (rises) against the bias of the return spring 18, and when the pulling operation by the operation lever 1 is stopped, the bias of the return spring 18 stops the male. The rail piece 12B (spray bowl holder 11) is lowered and returned to its original position.
[0020]
The spray bowl holder 11 holds a commercially available spray bowl 10 in which the nozzle 10B ′ made of a tube is detachably attached. The pressure receiving piece erected on the holder substrate 13 16 is brought into contact with the tip end surface of the nozzle material 10B of the spray bottle 10 inserted into the holder cylinder 14, and the pressing piece 15 is brought into contact with the rear end face (bottom face) of the spray bowl 10. The nozzle 10 </ b> B ′ is inserted into the nozzle material 10 </ b> B and assembled through the through hole provided in the pressure receiving piece 16.

[0022]
The reason why the long hole 39 is provided in the one piece 15b of the pressing piece 15 along the longitudinal direction of the holder cylinder 14 is to adjust the positional relationship between the pressing piece 15 and the spray basket 10.
[0023]
The operation piece 21 having the pressing piece 15 assembled on the rear end side is held by the holder cylinder 14 and a pair of holding pieces 22 and 22 ′ bolted to the holder cylinder 14. The second support rods 23, 23 are arranged on the intermediate portion of the operation piece 21 between the holding pieces 22, 22 ′ and the holding piece 22 holding the distal end side of the operation piece 21, respectively. The coil spring 24 stretched between them is urged so as to move toward the tip of the spray cup holder 11 (holder cylinder 14). The urge is provided by the pressing element 25 provided at the tip of the operation piece 21. The guide piece 26 provided on the base frame 6 side and the sliding contact edges 28 and 29 of the control piece 27 are pressed and regulated.
[0024]
One guide piece 6A constituting the device base frame 6 is fixed to the guide piece 26 having an L-shaped cross section composed of an attachment piece 26a and a guide piece 26b by a screw 31 together with a leaf spring 30 on the attachment piece 26a. The tip piece 30a of the leaf spring 30 is lightly pressed in the direction from the base piece 6a to the attachment piece 26a between the guide piece 26b of the guide piece 26 and the rising piece 30b of the leaf spring 30. The control piece 27 is slid and assembled with the control piece 27 interposed therebetween, and the control piece 27 is provided in a rectangular frame shape. The gap 32 is long in the direction along the longitudinal direction of the base piece 6A to the restriction piece 26. The control piece 27 is loosely fitted to the distal end portion 21A of the operation piece 21, and the inner surfaces 32 'and 32 are opposed to each other in the longitudinal direction of the gap 32 (in the moving direction of the interspray holder 11) by the distal end portion 21A of the operation piece 21. ″ Is pressed and its pressed Direction (i.e., longitudinal direction of the base piece 6A) are moving to a.
[0025]
The leaf spring 30 is configured by arranging the rising portion piece 30b between the attachment piece 30c and the tip piece 30a arranged in parallel with each other, and the attachment piece 30c is constituted by the attachment piece 26a of the guide piece 26. As described above, the control piece is fixed to the base piece 6A by the screw 31, the rising piece 30b forms a gap with the guide piece 26b of the restricting piece 26, and the control piece is slid into the gap. 27 is lightly pressed by the tip end piece 30a, and the state position of the control piece 27 is held in a state where the load of the external force through the tip end portion 21A of the operation piece 21 is interrupted. That is, the control piece 27 is placed at an appropriate position along the longitudinal direction of the restricting piece 26 when the leaf spring 30 is pressed.
[0026]
In the embodiment, the pressing element 25 provided on the distal end portion 21A side of the operation piece 21 is constituted by a roller, which is a sliding contact edge 28 constituted by the edge of the guide piece 26 and the control piece 27, and the generation of noise. 29, the coil spring 24 is smoothly moved while being pressed by the action of the coil spring 24. If these are neglected, the roller type is not a problem.
[0027]
Further, the pressing element 25 is arranged on one side of the operation piece 21 on the holder tube 14 side, that is, on one side where the pressing piece 15 presses the bottom surface of the spray bowl 10, and is urged by the coil spring 24. The sliding contact edge 28 on the guide piece 26 side and the sliding contact edge 29 on the control piece 27 side are always in pressure contact with each other.
[0028]
The sliding contact edge 28 on the guide piece 26 side has a start point portion (one end in the longitudinal direction of the guide piece 26) and an end point portion (the other end in the longitudinal direction of the guide piece 26) that moves against the bias of the return spring 18. ) As projecting edges (straight edges) 28a, 28a ', an intermediate portion between the projecting edges 28a, 28a' is formed as a recessed edge 28b, and a presser 15 is provided at the recessed edge 28b with a coil spring 24. The operating piece 21 provided with the pressing element 15 also moves in the direction in which the pressing element 15 engages with the recessed edge portion 28b, that is, from the rear end of the operating piece to the front end direction. 15 is in such a relationship as to press the spray bowl main body 10A.
[0029]
In the sliding contact edge 29 on the control piece 27 side, one end 21A ′ of the drive piece tip 21A engaged with the gap 32 of the control piece 27 is connected to one end (one inner surface of the control piece 21) 32 ′ of the gap 32. A concave insertion edge 29b is provided on one half side in such a positional relationship that the pressing element 25 engages when contacted, and the other end 21A ″ is the other end of the gap 32 (the other inner surface of the control piece 21). A protruding edge portion (straight edge) 29a is provided on the other half side adjacent to the concave insertion edge 29b in such a positional relationship that the pressing element 25 engages with the contact 32 ″.
[0030]
That is, when the return spring 18 is not acting on the spray cup holder 11, the operation piece tip 21A is on one end (one inner surface) 32 'side of the gap 32, and the control piece is controlled by the positional relationship of the tip 21A. 27 is in a position biased toward one end side of the guide piece 26, and the concave insertion edge portion 29 on the control piece 27 side and one protruding edge portion 28a on the guide piece 26 side are in a positional relationship where they overlap each other. Thus, the engagement of the pressing element 25 by the biasing force of the coil spring 24 with the concave insertion edge portion 29b on the control piece 27 side is prevented by the presence of the protruding edge portion 28a on the guide piece 26 side. . In this way, when the pressing element 25 is in a positional relationship in which the protrusions 28a, 28a ', 29a of the guide piece 22 and the control piece 27 are in contact with each other, the engagement of the pressing element 25 with the recessed edges 28b, 29b is restricted. Only when the recessed edges 28b and 29b coincide with each other, the operation piece 21 moves forward by the action of the coil spring 24 so that the pressing element 25 engages with the recessed edges 28b and 29b of the sliding contact edges 28 and 29. It is.
[0031]
Thus, when the spray bottle 10 is assembled to the spray bottle holder 11 such that the nozzle material 10B is disposed on the pressure receiving piece 16 side and the bottle body 10A is disposed on the pressure piece 15 side and is sandwiched between the two pieces 16 and 15, the pressure piece 15 is urged by the coil spring 24 to move toward the tip end side of the holder, that is, toward the pressure receiving piece 16, so that the pressing piece 15 is the main body of the spray bowl 10. 10A is constantly pressed in the direction of the pressure receiving piece 16. The pressing (movement of the pressing piece) is regulated by the pressing element 25 provided on the distal end side of the operation piece 21 coming into contact with the protruding edge portion 28a of the sliding contact edge 28 provided on the guide piece 26 (at this time, The pressing element 25 is also located at the position of the recessed edge 29b of the sliding contact edge 29 of the control piece 27). Therefore, the nozzle of the spray bottle 10 is not opened.
[0032]
Thus, the operation is performed by positioning the engaging piece 5 so as to be engaged with the bolt head a of the fastening device B in the state where the spray basket holder 10 is assembled, and assembling it on the upper end portion of the column 2 serving as a handle. When the lever 1 is operated and the wire body 3 is pulled against the urging force of the return spring 18, the tip of the wire body 3 is connected to the spray rod holder 11. It moves and rises along the inclined lower part 6 ″ of the device base frame 6.
[0033]
During the movement (raising) of the spray bowl holder 11, the operation piece 21 assembled (mounted) on the spray bowl holder 11 is also moved along with the movement direction of the holder, and the tip 21A of the operation piece 21 is moved. The air gap 32 is moved from one end (one inner surface) 32 ′ side to the other end (the other inner surface) 32 ″ side against the urging force of the return spring 18 to press the control piece 27. Move. At this time, the pressing element 25 that is in contact with one protruding edge portion 28a of the sliding contact edge 28 on the guide piece 26 side moves to the position of the recessed edge portion 28b, but at the same time, the sliding contact edge 29 on the control piece 27 side. Therefore, the biasing action of the coil spring 24 is restricted, and the operation piece 21, that is, the pressing element 25 maintains the original position in the direction in which the coil spring 24 acts. To do. That is, when the control piece 27 is moved along with the movement of the operation piece 21 against the urging of the coil spring 24, the presser 25 is in contact (pressure contact) with the protrusion 29 a of the sliding contact edge 29 of the control piece 27. The bias of the coil spring 24 does not appear on the pressing piece 15 side.
[0034]
Then, when the control piece 27 is moved to the moving dead center position, the pressing element 25 comes to a position where the guide piece 26 and the sliding contact edges 28, 29 of the control piece 27 come into contact with the overlapping protruding edges 28a ', 29a. In addition, the recessed edges 28b and 29b of the sliding contact edges 28 and 29 of the two pieces 26 and 27 are positioned so as to overlap each other (in short, during the forward movement of the control piece 27, the control piece 27 The pressing element 25 comes into contact with the projecting edge portion 29a, and the biasing action of the coil spring 24 is restricted). When the pulling operation of the wire body 3 by the operating lever 1 is stopped in this state, the return spring 18 is in a free state, and the spray rod holder 11 assembled (mounted) with the spray rod 10 by the bias of the return spring is in its original position. Since the operation piece 21 also moves in the original position direction in an attempt to return (lower) in the direction, the distal end portion 21A of the operation piece 21 moves in the gap 32 of the control piece 21 and has one end (one side) 32. It moves from ″ to the other end (one side) 32 ′ and presses it, and moves by pressing (with) the control piece 27. At this time, the pressing element 25 is moved to the control piece. 27 and the slidable contact edges 28 and 29 of the guide piece 26 are engaged from the positions of the protruding edges 28a 'and 29a to the positions of the recessed edges 28b and 29b by the urging of the coil spring 24. For the length of the recessed edge 28b The engagement state is continued. In this engaged state, the pressing piece 15 provided on the operation piece 21 by the biasing force of the coil spring 24 presses the rod main body 10A of the spray rod 16, and the pressure receiving piece 16 on the nozzle material 10B side receives the external force. Therefore, the bag main body 10A moves, the nozzle is opened, the paint (liquid) in the main body is sprayed and ejected, and the marker m is applied to the fastening device B in a linear shape. . As described above, the ejection operation is performed for the length of the concave insertion edge portion 28b on the guide piece 26 side, that is, for the time during which the presser 25 is engaged with the concave insertion edge portion 28b. The length is determined by the strength of the return spring 18, and the stronger it is, the shorter the time is, and the linear shape of the marker m ejected from the nozzle 10B 'appears more clearly.
[0035]
When the control piece 27 returns to the original position (the action of the return spring 18 is stopped), the pressing element 25 rides again on the protruding edge portion 28a of the sliding contact edge 28 of the guide piece 26, and the nozzle Is blocked.
[0036]
In addition, when the control piece 27 of the embodiment is omitted, spraying from the nozzle is performed while the pressing element 25 is in the recessed edge portion 28b position when the sliding contact edge 28 is reciprocated.
[0037]
The reason why the spraying operation is performed only when the elasticity of the return spring 18 acts as in the embodiment is that spraying is performed in a constant state by the strength of the return spring 18 and a uniform operation can be desired. It is.
[0038]
【The invention's effect】
Since the present invention is configured as described above, it is possible to provide a device that can reliably open the nozzle of the spray bottle by mechanical operation and can be used in various fields.
