Description

【０００１】
【発明の属する技術分野】
本発明は、レーザー光を壁面等の造営面に投影して墨出し作業を行う墨出し器を支持する墨出し器用回転台に関するものである。
【０００２】
【従来の技術】
従来より、レーザー光を円筒レンズを利用して扇形に広がるライン光とし、このライン光を壁面や天井面に投射することで墨出しを行うレーザー墨出し器が提供されている。
【０００３】
【発明が解決しようとする課題】
一般に、上述したレーザー墨出し器を用いて一つの壁面にレーザ光を投影し墨出し作業を行った後、この壁面に隣接し、この壁面に対して略直交する壁面にレーザ光を投影する場合、レーザー墨出し器自体を直接床面上で動かして、レーザー光の向きを変化させていた。
【０００４】
ところで、レーザー墨出し器の向きを変化させると、地墨がずれてしまい、再度地墨を合わせる必要があり、墨出し作業の作業性が作業性が低下するという問題があった。
【０００５】
本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、レーザー光を投影する方向を変化させたとしても地墨を合わせ直す必要がない墨出し器用回転台を提供するにある。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、請求項１の発明では、墨出し器本体及びこの墨出し器本体に一端が連結された少なくとも３本の支持脚を有する墨出し器を、床面に対して平行な面内で回転自在に支持する墨出し器用回転台において、墨出し器が取り付けられる回転台本体と、床面上に載置され、回転台本体を回転自在に支持する台座とを備え、回転台本体に各支持脚の先端をそれぞれ引掛係止する係止部を設け、係止部の内の少なくとも１つを、支持脚の先端を引掛係止する係止位置と非係止位置との間で移動自在に移動するスライダにより構成し、当該スライダが取り付けられる前記回転台本体の部位に回転台本体を貫通する開口を設け、前記開口の端面に向かって突出する突起が先端に設けられた弾性片をスライダと一体に設けるとともに、前記開口の端面に、前記係止位置において前記突起に設けた係止凹部と係止する係止突起と、前記非係止位置において前記突起と係止する抜止用突起と、前記スライダが前記回転台本体の裏面側から前記開口内に挿入された際に前記スライダの移動方向と交差する方向における前記スライダの両側部が載置される載置部とを設け、前記スライダを、前記支持脚の先端と引掛係止する引掛係止部を具備し前記回転台本体の開口に裏面側から挿入された際に前記開口を通して表面から上側に突出するスライダ本体と、スライダ本体の裏面側に一体的に設けられ前記載置部に載置される挟持部とで構成し、前記開口に前記スライダを挿入した状態から前記スライダを係止位置又は非係止位置に移動させた際に、前記スライダ本体の前記引掛係止部が設けられた部位を回転台本体の上面に乗り上げさせることを特徴とする。而して台座は、墨出し器が取り付けられる回転台本体を回転自在に支持しており、墨出し器の向きを変える際には回転台本体を回転させれば良いから、墨出し器の向きを変える際に地墨の位置がずれることはなく、墨出し器の向きを変える度に地墨の位置を合わせ直す必要がないので、墨出し作業の作業性が向上する。しかも、スライダは係止位置と非係止位置との間で移動自在に設けられているので、スライダを非係止位置に移動させた状態で他の係止部と支持脚の先端とを引掛係止させた後に、スライダを係止位置に移動させると、スライダと支持脚の先端とが引掛係止して、墨出し器を回転台本体に取り付けることができ、墨出し器をねじなどを用いて着脱する場合に比べて、墨出し器の着脱作業を容易に行うことができる。しかも、係止位置ではスライダの突起に設けた係止凹部が係止突起と係止し、非係止位置ではスライダの突起が抜止用突起と係止するので、スライダを係止位置又は非係止位置に保持することができ、墨出し器を回転台本体に取り付ける際に、スライダの位置から墨出し器の取付状態を容易に確認でき、墨出し器を回転台本体に確実に取り付けることができる。そのうえ、スライダを係止位置又は非係止位置に移動させた際には、引掛係止部の設けられたスライダ本体の部位が回転台本体の上面に乗り上げているから、スライダ本体の一部と挟持部との間に載置部を含む回転台本体の部位を挟持することによって、スライダを回転台本体に取り付けることができる。
【０００７】
請求項２の発明では、請求項１記載の発明において、スライダに、墨出し器側に向かって突出する摘み片を設けたことを特徴とし、請求項１記載の発明の作用に加え、摘み片を持ってスライダを移動させることができ、墨出し器の着脱作業が更に容易になる。
【０００８】
請求項３の発明では、請求項２記載の発明において、係止位置と非係止位置との間で摘み片に対応する回転台本体の部位に操作用孔を設けたことを特徴とすし、請求項２記載の発明の作用に加え、操作用孔内に指を差し入れることができるので、摘み片が持ちやすくなり、墨出し器の着脱作業が更に容易になる。
【００１１】
請求項４の発明では、請求項１乃至３の何れかの発明において、係止部が設けられた回転台本体の部位に、係止部に引掛係止される支持脚の周りを囲む包囲壁を設けたことを特徴とし、請求項１乃至３記載の発明の作用に加え、包囲壁を持って回転台本体を回転させることができ、回転操作を容易に行える。
【００１２】
【発明の実施の形態】
以下に本発明の実施の形態を図１乃至図１６を参照して説明する。
【００１３】
本実施形態の墨出し器用回転台１は、レーザー墨出し器５０が取り付けられる回転台本体２と、床面上に載置され回転台本体２を回転自在に支持する台座３とで構成される。尚、以下では特に説明がない場合、墨出し器用回転台１上にレーザー墨出し器５０を載置した状態で床面側を下側、レーザー墨出し器５０側を上側として説明を行う。
【００１４】
回転台本体２は例えばＡＢＳ樹脂のような熱可塑性樹脂の樹脂成型品からなり、略円板状の主部４と、主部４の全周縁から背面側に突出する側壁５とを一体に形成した略皿形としてあり、主部４の中心には主部４を貫通する丸孔状の貫通孔６が穿設されている。主部４の周縁部には側方に向かって突出する３個の張出部７が例えば１２０度毎に設けられており、これらの張出部７には後述するレーザー墨出し器５０の支持脚５２がそれぞれ載置されている。各張出部７の周縁部には包囲壁３３が立設されており、包囲壁３３が支持脚５２の周りを取り囲んでいるので、包囲壁３３を持って回転台本体２を回転させることができ、回転台本体２の回転作業を容易に行える。また、図５に示すように主部４の裏面には、裏面側に向かって突出する円弧状の当接リブ８が突設されている。この当接リブ８は張出部７に対応する部分が切り欠かれて３個のリブ８ａ〜８ｃに分割されており、３個のリブ８ａ〜８ｃは貫通孔６の中心を中心とする同一円周上に配置されている。
【００１５】
一方、台座３は例えばＡＢＳ樹脂のような熱可塑性樹脂の樹脂成型品からなり、略円板状であって、外径寸法が回転台本体２の外径寸法よりも若干大きい寸法に形成されており、上面には回転台本体２が嵌合する円形の凹所９が形成されている。台座３の周縁部には側方に向かって突出する３個の張出部１０が例えば１２０度毎に設けられており、各張出部１０は上面側から見て回転台本体２の外側に突出しているので、回転台本体２を回転させる際に、張出部１０を手で押さえて台座３が回転台本体２とともに回転するのを防止することができ、墨出し作業を正確に行うことができる。
【００１６】
３個の張出部１０の内の１つには台座３が床面に対して水平であるか否かを示す水準器１１が上面略中央に設けられ、残りの２つの張出部１０には調整ねじ１２が螺合するねじ孔（図示せず）が設けられている。ここで、水準器１１が設けられた張出部１０の裏面には突起１３が突設され、他の２つの張出部１０の裏面には上面側から螺入された調整ねじ１２のねじ部１２ａ先端が突出しており、２本の調整ねじ１２のねじ部１２ａ先端と突起１３とが床面に接触することによって、台座３が３点で支持される。したがって、２本の調整ねじ１２のねじ込み量を変化させて、ねじ部１２ａ先端の床面側への突出量を変化させると、床面に対する台座３の角度が変化するので、水準器１１の指標を見ながら調整ねじ１２のねじ込み量を調整することにより、台座３を床面に対して略水平な状態に保つことができる。尚、水準器１１及び調整ねじ１２が配置される張出部１０は上面側から見て回転台本体２よりも外側に位置しているので、回転台本体２を回転させる際に水準器１１や調整ねじ１２が邪魔になることはない。
【００１７】
台座３に設けた凹所９の底面には、貫通孔６の中心を中心とする円周状の挟持リブ１８が二重に形成されており、この２つの挟持リブ１８は回転台本体２と台座３とを結合した際に回転台本体２に設けた当接リブ８を間に挟むような位置に設けられている。また台座３に設けた凹所９の略中央には、回転台本体２側に向かって突出し、回転台本体２の貫通孔６と嵌合する円筒状の筒部１５が一体に形成されている。筒部１５の上側縁には４個の弾性係止片１７が例えば約９０度毎に設けられ、各弾性係止片１７の上端部には外側に突出する係止爪１６が突設されている。なお、各弾性係止片１７の両側には上端部に開放される切り溝１７ａが形成されており、各弾性係止片１７が厚み方向において撓みやすくなっている。
【００１８】
而して、回転台本体２を台座３に取り付ける際は、回転台本体２の当接リブ８が形成された面を台座３側にして、台座３の上方から回転台本体２を台座３の凹所９内に挿入すると、図８及び図１３に示すように回転台本体２の当接リブ８が台座３の挟持リブ１８の間に挿入されて、当接リブ８が両挟持リブ１８の間に挟持されるとともに、回転台本体２の貫通孔６内に筒部１５の上端部が挿入されて、弾性係止片１７の係止爪１６が貫通孔６の開口縁に設けられた段部６ａと係止し、回転台本体２が貫通孔６の中心を中心として回転自在に台座３に取り付けられる。尚、係止爪１６には外側に傾斜するテーパ面１６ａが設けられており、筒部１５を貫通孔６内に押し込んだ時に係止爪１６のテーパ面１６ａが貫通孔６の内周面と当接し、弾性係止片１７がテーパ面１６ａに沿って内側に撓められるので、回転台本体２と台座３との取付作業を容易に行うことができる。
【００１９】
ここで、図１３に示すように、当接リブ８の高さ寸法は、回転台本体２と台座３とを結合した際に当接リブ８の下面が台座３の凹所９と接触するような高さ寸法に設定されており、また回転台本体２を台座３側に押す力が加わっていない状態では側壁５の下面が凹所９と接触していないため、回転台本体２と台座３とは当接リブ８のみで接触することになり、回転台本体２と台座３との間の摩擦を少なくして、回転台本体２をスムーズに回転させることができる。なお、２つの挟持リブ１８の間にできる溝１９にはグリースを塗布してあり、当接リブ８と挟持リブ１８との間の摩擦を少なくして、回転台本体２をさらにスムーズに回転させることができ、且つグリースは２つの挟持リブ１８と当接リブ８との間に塗布されているので、グリースが挟持リブ１８と当接リブ８との間からはみ出しにくくなる。ここで、本実施形態では潤滑剤としてグリースを用いているが、回転台本体２と台座３との間の摩擦を低減できるものであればグリース以外の潤滑剤を用いても良いことは言うまでもない。
【００２０】
また、側壁５の高さ寸法は、回転台本体２に回転台本体２を台座３側に押す力が加わると、側壁５の下面が凹所９と接触するような寸法に設定されているので、回転台本体２に加わった力を当接リブ８と側壁５とで受けることができ、回転台本体２が破損するのを防止できる。尚、図８、図１０、図１２及び図１３では回転台本体２を台座３側に押す力が加えられ、側壁５の下面が凹所９と接触している状態を示している。
【００２１】
一方、レーザー墨出し器５０は、上下に細長い円筒状の墨出し器本体５１と、この墨出し器本体５１の下端に開閉自在に連結された３本の支持脚５２とを有し、墨出し器本体５１の内部には半導体レーザーのような光源や、光源から出力されたレーザー光を偏向させることにより鉛直方向及び水平方向において扇状に広がったライン光を生成する円筒レンズなどの光学系が納装されている。支持脚５２の一端は墨出し器本体５１に回動自在に軸支されており、開いた際に三脚として機能し、閉じた際には墨出し器本体５１に連続して全体を一つの棒状の形態としている。また支持脚５２の先端部には内側に向かって突出する引掛片５３がそれぞれ突設されている。
【００２２】
レーザー墨出し器５０の３本の支持脚５２は、回転台本体２に設けた３箇所の張出部７にそれぞれ載置されるのであるが、３箇所の張出部７の内の１箇所には、支持脚５２の引掛片５３と引掛係止する一対の係止爪２０が固定的に設けられている。また他の２箇所の張出部７に対応する主部４の部位には、支持脚５２の引掛片５３と引掛係止する係止凹部（引掛係止部）２４を有し、引掛片５３と係止凹部２４とが引掛係止する係止位置と、係止しない非係止位置との間で移動自在に移動するスライダ２２がそれぞれ取り付けられている。ここで、各支持脚５２の引掛片５３と係止爪２０及びスライダ２２とをそれぞれ引掛係止させて、レーザー墨出し器５０を回転台本体２に取り付けると、レーザー墨出し器５０の中心位置と回転台本体２の回転中心とが略一致するようになっている。スライダ２２は係止位置と非係止位置との間で移動自在に設けられているので、スライダ２２を係止位置又は非係止位置に移動させることによって、レーザー墨出し器５０の着脱作業を行うことができ、レーザー墨出し器５０の支持脚５２を回転台本体２にねじ止めする場合に比べて、レーザー墨出し器５０の支持脚５２の着脱作業が容易になる。ここに、係止爪２０及びスライダ２２から各支持脚５２の先端を引掛係止する係止部が構成される。
【００２３】
ここで、スライダ２２が取り付けられる主部４の部位には、主部４の中心側から張出部７側にかけて主部４を貫通する開口２１が開口しており、この開口２１内にスライダ２２が裏面側から挿入される。尚、開口２１は中心側の端部に他の部位よりも幅の広い幅広部２１ａを有し、幅狭部２１ｂの両側縁には裏面側から見て一段低くなった載置部２１ｃが形成されている。
【００２４】
スライダ２２は、略直方体状であって短幅方向の寸法が開口２１の幅狭部２１ｂの寸法よりも若干小さい寸法に形成され、回転台本体２の裏面側から開口２１内に挿入された際に開口２１から上面側に露出するスライダ本体２３を有し、スライダ本体２３における張出部７側の端部には先端面の下側略中央を窪ませることによって、支持脚５２の引掛片５３と引掛係止する係止凹部２４が設けられ、主部４の中心側の端部には上方に突出する摘み片２５が一体に突設されている。ここで、摘み片２５の幅寸法は開口２１の幅広部２１ａの幅寸法よりも小さく、且つ、幅狭部２１ｂの幅寸法よりも大きい寸法に形成されている。
【００２５】
また、スライダ本体２３の裏面には短幅方向における略中央に下方に突出するリブ２６が設けられ、リブ２６の両側部には弾性押圧片２７，２７が設けられている。弾性押圧片２７，２７は摘み片２５側の端部でスライダ本体２３に連結されており、反対側の端部が自由端となっている。各弾性押圧片２７の下部には外側（すなわちリブ２６と反対側）に向かって突出し、スライダ本体２３を回転台本体２の裏面側から開口２１内に挿入した際に載置部２１ｃ上に載置される挟持部としての係止段部２８がそれぞれ形成される。そして、各係止段部２８の長手方向における両端部にはそれぞれ外側に向かって突出する突起２９，３０が突設されており、外周側の突起３０の先端面には谷状に凹んだ係止凹部３０ａが設けられている。
【００２６】
一方、開口２１の端面には、スライダ２２を裏面側から開口２１内に挿入した状態（図７及び図８参照）から非係止位置まで移動させた際に（図９及び図１０参照）、弾性押圧片２７に設けた突起３０と当接してスライダ２２の抜止を行う抜止用突起３１が突設されており、さらにスライダ２２が図１１及び図１２に示すように係止位置まで移動した状態で係止凹部３０ａと凹凸係止する係止突起３２が突設されている。ここで、係止突起３２にはテーパ面３２ａが形成されているので、スライダ２２を非係止位置から係止位置に移動させる際、又は、係止位置から非係止位置に移動させる際に、弾性押圧片２７の突起３０がテーパ面３２ａに沿って移動することによって、弾性押圧片２７が内側に撓められるため、スライダ２２を係止位置と非係止位置との間でスムーズに移動させることができる。
【００２７】
而して、スライダ２２を回転台本体２に取り付ける際は、係止凹部２４を外周側、摘み片２５を中心側とし、開口２１の幅広部２１ａと摘み片２５との位置を合わせて、スライダ２２を回転台本体２の裏面側から開口２１内に挿入すると、スライダ本体２３が開口２１から表面側に露出する（図７及び図８参照）。この時、弾性押圧片２７の係止段部２８が、開口２１の開口縁に設けた載置部２１ｃと当接し、スライダ本体２３の表面側への移動が規制される。
【００２８】
その後、スライダ２２を主部４の外周側へ移動させると、スライダ本体２３が開口２１の幅狭部２１ｂ内に案内され、弾性押圧片２７の突起３０が開口２１の端面に設けた抜止用突起３１と当接して、内側（リブ２６に近付く側）に撓められる。この状態からさらに外周側へスライダ２２を移動させると、突起３０が抜止用突起３１を乗り越えて、突起３０が係止突起３２と抜止用突起３１との間に保持される（図９参照）。またこの時、図１０に示すように、スライダ本体２３の外周側の端部が主部４上に乗り上げるとともに、摘み片２５の両側部が載置部２１ｃ上に乗り上げるので、スライダ本体２３の外周側の端部及び摘み片２５と係止段部２８との間に主部４が挟持することによって、スライダ２２を回転台本体２に容易に取り付けることができる。
【００２９】
そして、この状態から更にスライダ２２を主部４の外周側へ移動させると、弾性押圧片２７の突起３０が、開口２１の端面に設けた係止突起３２のテーパ面３２ａに沿って移動し、突起３０の係止凹部３０ａと係止突起３２とが凹凸係止する（図１１参照）。また、図１２に示すようにスライダ２２が係止位置に移動した場合にも、スライダ本体２３の外周側の端部が主部４上に乗り上げるとともに、摘み片２５の両側部が載置部２１ｃ上に乗り上げているので、スライダ本体２３の外周側の端部及び摘み片２５と係止段部２８との間に主部４を挟持することによって、スライダ２２を回転台本体２に容易に取り付けることができる。また、スライダ本体２３の先端面に設けた係止凹部２４と支持脚５２の引掛片５３とが引掛係止し、レーザー墨出し器５０が回転台本体２に固定される。
【００３０】
ここで、スライダ２２を回転台本体２の裏面側から開口２１内に挿入すると、スライダ本体２３に設けた摘み片２５は開口２１から上面側に突出し、摘み片２５を摘んでスライダ２２を移動させることができるから、レーザー墨出し器５０の着脱作業を容易に行える。また、スライダ２２を非係止位置と係止位置との間で移動させる際は、主部４の中心側と摘み片２５との間に操作用孔たる開口２１が開口しているので、開口２１内に手を入れて摘み片２５を操作することができ、スライダ２２の移動操作をさらに容易に行うことができる。
【００３１】
また、開口２１の端面には係止位置及び非係止位置でスライダ２２とそれぞれ係止する係止手段としての抜止用突起３１及び係止突起３２が設けられているので、スライダ２２を係止位置又は非係止位置に保持することができ、スライダ２２の位置からレーザー墨出し器５０の支持脚５２が引掛係止されているか否かを容易に判断でき、レーザー墨出し器５０を回転台本体２に確実に取り付けることができる。
【００３２】
ところで、主部４の周縁部には張出部７が設けられた部位を除く部位に外側に行くほど背面側に傾斜する傾斜面４ａが形成されており、この傾斜面４ａには基準位置を示す３個の指標４ｂが９０度毎に形成されている。尚、３個の指標４ｂの内、中央の指標４ｂは、主部４の中心に対して張出部１０と反対側に位置するように設けられている。
【００３３】
一方、台座３の外周縁には、回転台本体２の傾斜面４ａに連続し、外側に行くほど背面側（床面側）に傾斜する傾斜面３ａが設けられている。ここで、水準器１１が設けられた張出部１０には、回転台本体２を基準位置に回転させた時（すなわち、主部４の中心に対して中央の指標４ｂと反対側に位置する張出部７が、回転中心を挟んで水準器１１の設けられた張出部１０と反対側にくるように回転台本体２を回転させた時）に中央の指標４ｂと一致する部位に基準位置を示すための基準目盛３ｃが形成されている。また傾斜面３ａには、基準目盛３ｃの位置を基準にして例えば９０度毎に、補助目盛３ｃ’が回転台本体２の外周部に沿って設けられ、傾斜面３ａ及び張出部１０には、基準目盛３ｃ及び補助目盛３ｃ’の間に例えば５度おきに目盛３ｂが回転台本体２の外周部に沿って形成されている。そして、基準目盛３ｃと中心位置を通る直線、及び、この直線に直交する直線が筒部１５の内周面と交差する部位には内側に突出する位置決め突起１５ａが４個突設されている。
【００３４】
ここで、床面に引かれた基準線に台座３の位置及び方向を合わせる際は、筒部１５の内周面に設けた位置決め突起１５ａと床面の基準線とを合わせることによって行っているが、位置決め突起１５ａは筒部１５の内周面に形成されているので、回転台本体２に形成された貫通孔６と筒部１５の開口１４とを通して位置決め突起１５ａと床面の基準線とを見ながら位置合わせの作業を行うことができ、台座３と床面の基準線との位置合わせを容易に行える。
【００３５】
このように台座３と床面の基準線との位置合わせを行い、レーザー墨出し器５０と地墨の位置とを合わせた状態で、墨出し作業を行うのであるが、図４に示すように一方の壁面に鉛直方向或いは水平方向にレーザー光Ａ，Ｂを投影して墨出し作業を行った後、この壁面に隣接する別の壁面にレーザー光を照射させる場合、本実施形態では回転台本体２を台座３に対して回転させることにより、レーザー墨出し器５０の向きを変えて、別の壁面にレーザー光を照射させている。
【００３６】
すなわち、図１４に示すように中央の指標４ｂを基準目盛３ｃと合わせた状態から、回転台本体２を図中左回りに約９０度回転させ、図１５に示すように中央の指標４ｂが所望の目盛３ｂと一致するように回転台本体２を回転させると、基準位置から所望の角度だけ回転台本体２を回転させることができ、所望の方向にレーザー光を投影させることができる。この時、レーザー墨出し器５０自体を直接動かしていないので、地墨の位置がずれることはなく、レーザー墨出し器５０の向きを変える度に地墨の位置を合わせ直す必要がないので、墨出し作業の作業性が向上する。尚、図１３に示すように回転台本体２に設けた傾斜面４ａと台座３に設けた傾斜面３ａとは傾斜面４ａが上側、傾斜面３ａが下側に配置され、略連続した傾斜面となっているので、傾斜面４ａに形成された指標４ｂと傾斜面３ａ及び張出部１０に形成された目盛３ｂ、基準目盛３ｃ及び補助目盛３ｃ’との対応関係が見易くなっており、台座３に対する回転台本体２の位置合わせを容易に行うことができる。また、基準目盛３ｃは張出部１０に設けられているので、基準目盛３ｃの位置がわかりやすく、基準目盛３ｃを容易に見つけることができる。
【００３７】
ところで、台座３を直接床面上に載置する代わりに、台座３を三脚に取り付けるようにしても良い。台座３を三脚に取り付ける場合は、図１６に示すように、略円盤状に形成されたホルダー３４を用い、ホルダー３４の下面に突設された円柱状の凸部３４ａを台座３の筒部１５内に挿入し、台座３の下側に配置された三脚（図示せず）のねじを凸部３４ａの下面に設けたねじ穴に螺合することによって、ホルダー３４と三脚との間で台座３を挟持し、台座３を三脚に取り付けることができる。
【００３８】
尚、本実施形態では台座３に回転台本体２が挿入される凹所９を形成するとともに、回転台本体２に当接リブ８を設けているが、回転台本体２に凹所を設けるとともに、回転台本体２に設けた凹所と当接する当接リブを台座３に設け、台座３に設けた当接リブを挟持する挟持リブを回転台本体２に設けるようにしても良い。

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to FIGS.
[0013]
The turnout 1 for the marking device of the present embodiment includes a turntable main body 2 to which a laser marking device 50 is attached, and a pedestal 3 that is placed on the floor and rotatably supports the turntable main body 2. . In the following description, when there is no particular description, the laser marking device 50 is placed on the marking table turntable 1 and the floor side is the lower side and the laser marking device 50 side is the upper side.
[0014]
The turntable body 2 is made of a resin molded product of a thermoplastic resin such as ABS resin, for example, and is formed integrally with a substantially disc-shaped main portion 4 and a side wall 5 that protrudes from the entire periphery of the main portion 4 to the back side. In the center of the main portion 4, a round hole-like through hole 6 that penetrates the main portion 4 is formed. Three protruding portions 7 projecting sideways are provided on the peripheral edge of the main portion 4 at every 120 degrees, for example, and these protruding portions 7 support a laser marking device 50 described later. Legs 52 are respectively placed. Since the surrounding wall 33 is erected on the peripheral edge of each overhang 7 and the surrounding wall 33 surrounds the support leg 52, the turntable body 2 can be rotated by holding the surrounding wall 33. The rotation work of the turntable body 2 can be easily performed. Further, as shown in FIG. 5, an arcuate abutting rib 8 protruding toward the back surface is provided on the back surface of the main portion 4. The contact rib 8 is divided into three ribs 8 a to 8 c by notching a portion corresponding to the protruding portion 7, and the three ribs 8 a to 8 c are the same with the center of the through hole 6 as the center. It is arranged on the circumference.
[0015]
On the other hand, the pedestal 3 is made of a resin molded product of a thermoplastic resin such as ABS resin, and has a substantially disc shape, and has an outer diameter dimension slightly larger than the outer diameter dimension of the turntable body 2. A circular recess 9 into which the turntable body 2 is fitted is formed on the upper surface. In the periphery of the pedestal 3, three projecting portions 10 projecting sideways are provided, for example, every 120 degrees, and each projecting portion 10 is provided on the outer side of the turntable body 2 when viewed from the upper surface side. Since it protrudes, when the turntable body 2 is rotated, it is possible to prevent the base 3 from rotating together with the turntable body 2 by pressing the overhanging portion 10 by hand, and to accurately perform the ink marking work. Can do.
[0016]
A level 11 indicating whether or not the pedestal 3 is horizontal with respect to the floor surface is provided in one of the three overhanging portions 10 at the substantially upper center of the upper surface. Is provided with a screw hole (not shown) into which the adjusting screw 12 is screwed. Here, a protrusion 13 is provided on the back surface of the overhanging portion 10 provided with the level 11, and the screw portion of the adjusting screw 12 screwed into the back surface of the other two overhanging portions 10 from the upper surface side. The tip of 12a protrudes, and the base 3 is supported at three points by the tips of the screw portions 12a of the two adjusting screws 12 and the projections 13 coming into contact with the floor surface. Therefore, if the amount of protrusion of the screw portion 12a to the floor surface side is changed by changing the screwing amount of the two adjusting screws 12, the angle of the pedestal 3 with respect to the floor surface changes. By adjusting the screwing amount of the adjusting screw 12 while looking at, the pedestal 3 can be kept substantially horizontal with respect to the floor surface. In addition, since the overhang | projection part 10 in which the level 11 and the adjustment screw 12 are arrange | positioned is located in the outer side rather than the turntable main body 2 seeing from the upper surface side, when rotating the turntable main body 2, the level 11 or The adjusting screw 12 does not get in the way.
[0017]
On the bottom surface of the recess 9 provided in the pedestal 3, a circular sandwiching rib 18 centering on the center of the through hole 6 is formed in a double, and these two sandwiching ribs 18 are connected to the turntable body 2. When the pedestal 3 is coupled, the abutment rib 8 provided on the turntable main body 2 is provided at a position sandwiched therebetween. A cylindrical tube portion 15 that protrudes toward the turntable main body 2 and fits with the through hole 6 of the turntable main body 2 is integrally formed at the approximate center of the recess 9 provided in the pedestal 3. . For example, four elastic locking pieces 17 are provided on the upper edge of the cylindrical portion 15 every about 90 degrees, and an locking claw 16 protruding outward is provided at the upper end of each elastic locking piece 17. Yes. A cut groove 17a that is open to the upper end portion is formed on both sides of each elastic locking piece 17, and each elastic locking piece 17 is easily bent in the thickness direction.
[0018]
Thus, when the turntable body 2 is attached to the pedestal 3, the surface of the turntable body 2 on which the contact ribs 8 are formed faces the pedestal 3, and the turntable body 2 is attached to the pedestal 3 from above the pedestal 3. When inserted into the recess 9, the abutment rib 8 of the turntable body 2 is inserted between the sandwiching ribs 18 of the base 3 as shown in FIGS. A step in which the upper end of the cylindrical portion 15 is inserted into the through hole 6 of the turntable body 2 and the locking claw 16 of the elastic locking piece 17 is provided at the opening edge of the through hole 6. The turntable body 2 is attached to the pedestal 3 so as to be rotatable about the center of the through hole 6. The locking claw 16 is provided with a tapered surface 16 a that is inclined outward. When the cylindrical portion 15 is pushed into the through hole 6, the tapered surface 16 a of the locking claw 16 is in contact with the inner peripheral surface of the through hole 6. Since the elastic locking pieces 17 are in contact with each other and bent inward along the tapered surface 16a, the mounting operation of the turntable body 2 and the pedestal 3 can be easily performed.
[0019]
Here, as shown in FIG. 13, the height of the abutment rib 8 is such that the lower surface of the abutment rib 8 contacts the recess 9 of the pedestal 3 when the rotary base body 2 and the pedestal 3 are coupled. Since the lower surface of the side wall 5 is not in contact with the recess 9 when no force is applied to the rotary base body 2 toward the base 3, the rotary base body 2 and the base 3 are not set. Therefore, the contact between the rotary base body 2 and the pedestal 3 is reduced, and the rotary base body 2 can be smoothly rotated. Grease is applied to the groove 19 formed between the two sandwiching ribs 18 to reduce friction between the contact ribs 8 and the sandwiching ribs 18 and to rotate the turntable body 2 more smoothly. In addition, since the grease is applied between the two sandwiching ribs 18 and the contact rib 8, it is difficult for the grease to protrude from between the sandwiching rib 18 and the contact rib 8. Here, although grease is used as the lubricant in the present embodiment, it goes without saying that a lubricant other than grease may be used as long as it can reduce friction between the turntable body 2 and the base 3. .
[0020]
Further, the height dimension of the side wall 5 is set such that the bottom surface of the side wall 5 comes into contact with the recess 9 when a force is applied to the turntable body 2 toward the pedestal 3 side. The force applied to the turntable body 2 can be received by the abutment rib 8 and the side wall 5, and the turntable body 2 can be prevented from being damaged. 8, 10, 12, and 13 show a state in which a force that pushes the turntable body 2 toward the pedestal 3 is applied and the lower surface of the side wall 5 is in contact with the recess 9.
[0021]
On the other hand, the laser marking device 50 has a cylindrical marking device body 51 that is vertically elongated, and three support legs 52 that are openably and closably connected to the lower end of the marking device body 51. An optical system such as a light source such as a semiconductor laser or a cylindrical lens that generates line light that spreads in a fan shape in the vertical and horizontal directions by deflecting the laser light output from the light source is housed in the main body 51. It is disguised. One end of the support leg 52 is pivotally supported by the inking unit main body 51 so as to function as a tripod when opened, and continuously to the inking unit main body 51 when closed. It is in the form of Further, hook pieces 53 projecting inwardly project from the tip end portions of the support legs 52.
[0022]

One of the three overhanging portions 7 is provided. A pair of locking claws 20 that are hooked and locked with the hooking piece 53 of the support leg 52 are fixedly provided. Further, the portion of the main portion 4 corresponding to the other two overhang portions 7 has a locking recess (hook locking portion) 24 for hooking and locking with the hook piece 53 of the support leg 52, and the hook piece 53. A slider 22 is attached to move freely between a locking position where the locking recess 24 is hooked and locked and a non-locking position where the locking recess 24 is not locked. Here, when the hooking piece 53 of each support leg 52 and the locking claw 20 and the slider 22 are hooked and locked and the laser marking device 50 is attached to the turntable body 2, the center position of the laser marking device 50 is set. And the center of rotation of the turntable body 2 substantially coincide with each other. Since the slider 22 is movably provided between the locking position and the non-locking position, the laser marking device 50 can be attached and detached by moving the slider 22 to the locking position or the non-locking position. Compared with the case where the support leg 52 of the laser marking device 50 is screwed to the turntable body 2, the attaching / detaching work of the supporting leg 52 of the laser marking device 50 is facilitated. Here, the locking claw 20 and the slider 22 constitute a locking portion that hooks and locks the tip of each support leg 52.
[0023]
Here, an opening 21 penetrating the main portion 4 is opened from the center side of the main portion 4 to the projecting portion 7 side at a portion of the main portion 4 to which the slider 22 is attached. Is inserted from the back side. The opening 21 has a wide portion 21a that is wider than the other portions at the end on the center side, and a mounting portion 21c that is one step lower when viewed from the back side is formed on both side edges of the narrow portion 21b. Has been.
[0024]
The slider 22 has a substantially rectangular parallelepiped shape, the dimension in the short width direction is slightly smaller than the dimension of the narrow portion 21 b of the opening 21, and the slider 22 is inserted into the opening 21 from the back side of the turntable body 2. The slider main body 23 is exposed from the opening 21 to the upper surface side, and the end of the slider main body 23 on the overhanging portion 7 side is recessed in the lower center of the front end surface, whereby the hook piece 53 of the support leg 52 is provided. A latching recess 24 for hooking and latching is provided, and a knob 25 projecting upward is integrally provided at an end of the main portion 4 on the center side. Here, the width of the knob 25 is smaller than the width of the wide portion 21a of the opening 21 and larger than the width of the narrow portion 21b.
[0025]
Further, on the back surface of the slider body 23, a rib 26 protruding downward is provided at a substantially center in the short width direction, and elastic pressing pieces 27, 27 are provided on both sides of the rib 26. The elastic pressing pieces 27, 27 are connected to the slider body 23 at the end on the side of the knob 25, and the opposite end is a free end. The lower part of each elastic pressing piece 27 protrudes toward the outside (that is, the side opposite to the rib 26), and is placed on the placement portion 21c when the slider body 23 is inserted into the opening 21 from the back side of the turntable body 2. A locking step portion 28 is formed as a holding portion to be placed. Further, projections 29 and 30 projecting outward are respectively provided at both end portions in the longitudinal direction of each locking step portion 28, and a trough-like engagement is formed on the distal end surface of the outer circumferential projection 30. A stop recess 30a is provided.
[0026]
On the other hand, when the slider 22 is moved from the back surface side to the unlocked position on the end surface of the opening 21 from the back surface side (see FIGS. 7 and 8) (see FIGS. 9 and 10), A projection 31 for preventing the slider 22 from coming into contact with the projection 30 provided on the elastic pressing piece 27 is projected, and the slider 22 is moved to the locking position as shown in FIGS. Thus, a locking protrusion 32 is provided to protrude from the locking recess 30a. Here, since the locking protrusion 32 has a tapered surface 32a, when the slider 22 is moved from the non-locking position to the locking position, or when the slider 22 is moved from the locking position to the non-locking position. When the protrusion 30 of the elastic pressing piece 27 moves along the tapered surface 32a, the elastic pressing piece 27 is bent inward, so that the slider 22 moves smoothly between the locking position and the non-locking position. Can be made.
[0027]
Thus, when the slider 22 is attached to the turntable body 2, the locking recess 24 is on the outer peripheral side, the knob piece 25 is on the center side, and the positions of the wide portion 21 a of the opening 21 and the knob piece 25 are aligned. When 22 is inserted into the opening 21 from the back side of the turntable body 2, the slider body 23 is exposed from the opening 21 to the front surface side (see FIGS. 7 and 8). At this time, the locking step portion 28 of the elastic pressing piece 27 comes into contact with the mounting portion 21 c provided at the opening edge of the opening 21, and the movement of the slider body 23 to the surface side is restricted.
[0028]
Thereafter, when the slider 22 is moved to the outer peripheral side of the main portion 4, the slider body 23 is guided into the narrow portion 21 b of the opening 21, and the protrusion 30 of the elastic pressing piece 27 is provided on the end face of the opening 21. It abuts 31 and is bent inward (side approaching the rib 26). When the slider 22 is further moved to the outer peripheral side from this state, the protrusion 30 gets over the retaining protrusion 31 and the protrusion 30 is held between the locking protrusion 32 and the retaining protrusion 31 (see FIG. 9). At this time, as shown in FIG. 10, the outer peripheral end of the slider body 23 rides on the main portion 4, and both side portions of the knob 25 run on the mounting portion 21 c, so The slider 22 can be easily attached to the turntable body 2 by sandwiching the main portion 4 between the side end portion and the knob 25 and the locking step portion 28.
[0029]
When the slider 22 is further moved to the outer peripheral side of the main portion 4 from this state, the protrusion 30 of the elastic pressing piece 27 moves along the taper surface 32a of the locking protrusion 32 provided on the end surface of the opening 21, The locking recess 30a of the protrusion 30 and the locking protrusion 32 engage with each other (see FIG. 11). Also, as shown in FIG. 12, even when the slider 22 is moved to the locking position, the outer peripheral end of the slider main body 23 rides on the main portion 4 and both side portions of the knob 25 are placed on the placement portions 21c. Since the main portion 4 is sandwiched between the outer peripheral end of the slider main body 23 and the knob 25 and the locking step portion 28, the slider 22 is easily attached to the turntable main body 2. be able to. In addition, the locking recess 24 provided on the front end surface of the slider body 23 and the hook piece 53 of the support leg 52 are hooked and locked, and the laser marking device 50 is fixed to the turntable body 2.
[0030]
Here, when the slider 22 is inserted into the opening 21 from the back side of the turntable body 2, the knob 25 provided on the slider body 23 protrudes from the opening 21 to the upper surface, and the slider 22 is moved by picking the knob 25. Therefore, the laser marking device 50 can be easily attached and detached. Further, when the slider 22 is moved between the non-locking position and the locking position, the opening 21 as the operation hole is opened between the center side of the main portion 4 and the knob 25, so that the opening The hand 25 can be put in and the knob 25 can be operated, and the slider 22 can be moved more easily.
[0031]
Further, since the end face of the opening 21 is provided with a protrusion 31 for locking and a locking protrusion 32 as locking means for locking with the slider 22 at the locking position and the non-locking position, the slider 22 is locked. It can be held at the position or the non-locking position, and it can be easily determined from the position of the slider 22 whether the support leg 52 of the laser marking device 50 is hooked and locked. It can be securely attached to the main body 2.
[0032]
By the way, an inclined surface 4a which is inclined to the back side as it goes outward is formed on the peripheral portion of the main portion 4 except for the portion where the overhanging portion 7 is provided, and a reference position is set on the inclined surface 4a. Three indexes 4b shown are formed every 90 degrees. Of the three indicators 4b, the central indicator 4b is provided on the opposite side of the overhanging portion 10 with respect to the center of the main portion 4.
