Description

【０００１】
【産業上の利用分野】
本発明は板金用引出し具に関するものであり、自動車ボディに形成されているプレスライン付近や自動車ドアの端部付近に生じる凹部といった特殊部位の引出しや、自動車ボディに生じるライン状の傷といった特殊な傷の引出しにも対応できる板金用引出し具に関するものである。
【０００２】
【従来の技術】
（発明の背景）
自動車ボディの板金作業においては、例えば、図１及び図２に示されるような自動車ドア３００に形成されたプレスライン３１０付近（上段部や根元）に生じる凹部３３０，３５０の引出し（修復）や、自動車ドア３００の端部３２０付近に生じる凹部３４０の引出しを迅速に行うことができ、また図３に示されるようなライン状の傷（長い溝傷や引っかき傷等）３６０の引出しを連続作業により行える板金用引出し具の出現が切望されている。
（従来技術）
従来、板金時に板金面の凹部を引き出すのに好都合な板金用引出し具として図２７乃至図２９に示される板金用引出し具が知られている。
【０００３】
【発明が解決しようとする課題】
この従来の板金用引出し具４０１にあっては、板金作業時に板金用引出し具の足場の位置を簡単に決められる（足場の位置決めに困らない）場合には板金面の平滑化を行うことがある程度可能であるが、板金面が特殊部位の場合や特殊の傷の場合には次の（１）（２）（３）の点が指摘されていた。すなわち、
（１）例えば、図３０及び図３１に示すように、板金面である引出したいポイントＰが自動車ドア３００のプレスライン３１０の近辺にあるような場合や、板金面である引き出したいポイントＱが自動車ドア３００の端部３２０の近辺にあるような場合には、板金用引出し具４０１の脚部４９１，４９２をセットし引き出したいポイントを引こうとしても、脚部４９１，４９２が通常の状態（脚部４９１，４９２が腕杆４３３Ａ，４３３Ｂに左右対称にバランスよく止められている状態）にセットされている場合には、接面部材４９３がプレスライン３１０や端部３２０からからはみ出てしまい（図３１の四角枠Ｓ３，Ｓ４の表示で示される足場の位置参照）、接面部材４９３により足場をしっかり確保し略均一な力で押さえることができないため、プレスライン３１０近辺や端部３２０近辺の引出し作業を迅速かつ確実に行えない［引き出したいポイントＰあるいはＱ（図３０乃至図３２参照）を引こうとするためには、先ず板金用引出し具４０１の本体及び脚部４９１，４９２の位置を図３０の状態から９０度ずらし、更に蝶ねじ４９６，４９７を緩めて一旦脚部４９１，４９２の位置を図３２に示すように左側に移動して脚部４９１，４９２の足場の位置決めを行い、その後蝶ねじ４９６，４９７を締めて接面部材４９３を所望の位置にセットし直す必要がある］。
（２）また、例えば、板金面である凹部が自動車ドアのプレスライン３１０の根元Ｒ（図３５参照）にあるような場合には、板金用引出し具４０１の脚部を図３３及び図３４に示すような脚部５９１，５９２に変え、この脚部５９１，５９２をプレスライン３１０に乗っけても（図３５参照）プレスライン３１０の根元Ｒの引出しができない（この点、引出し具４０１の本体及び脚部５９１，５９２の位置を９０度変えても脚部５９１，５９２の一方がプレスライン３１０の根元Ｒにかかり邪魔するためプスライン３１０の根元Ｒの引出しは結局できない）；
（３）引出し箇所が長い溝傷（鋭角な凹部が長く続く傷）や引っかき傷といったライン状の傷３６０のような場合には一回修復するごとにその都度板金用引出し具４０１の脚部における足場の位置を移動しセットして引出し作業を行う必要があり（図３６及び図３７参照）、引出し作業に時間がかかり作業効率が悪い；
等の点が指摘されていた。
【０００４】
従って、本発明の目的は、押さえたい場所を脚体で押さえ足場を位置決めしたまま操作手段を回動させてビットを引き出したい板金面の複数のポイントに自由に動かして使用できる板金用引出し具を提供することにある。
【０００５】
本発明の他の目的は、自動車ボディに形成されたプレスライン近辺（上段部）や根元、あるいは自動車ドアの端部のように通例板金作業が難しくかつ時間のかかる部位の場合でも、板金作業の際に板金引出し具の脚部の位置に制約されることなく（脚部の位置決めに煩わされることなく）、足場をしっかり確保しながら引き出したいポイントを自由に引くことができる板金用引出し具を提供することにある。
【０００６】
本発明のもう一つ他の目的は、板金面の引出し箇所が長い溝傷や引っかき傷といったライン状の傷の場合でも足場の位置を一旦セットすれば足場の移動を必要最小限度にしてその間連続作業による傷の引出しを行える板金用引出し具を提供することにある。
【０００７】
本発明の更にもう一つ他の目的は、構造がシンプルで部品点数が少なく軽量にして取り扱いが容易な板金用引出し具を提供することにある。
【０００８】

【００１５】
これらの図において、板金用引出し具１Ａは、板金面に溶着可能なビット１９を先端部に備えた第１の操作手段１０と、手動操作することにより前記第１の操作手段１０を引き上げる第２の操作手段２０と、前記第２の操作手段を支持する脚体５０と、前記第２の操作手段２０に軸支され、前記第１の操作手段１０を支承するとともに前記第１の操作手段１０と一体となって可動（回動）する軸体７０を具備している。
【００１６】
このうち、前記第１の操作手段１０は、シャフト１４と、このシャフト１４の一端に設けたシャフト回動用のハンドル１１とを具備し、前記シャフト１４の先端部に前記ビット１９が配設されている。即ち、前記第１の操作手段１０を構成する前記シャフト１４の一端部１４Ａは、前記ハンドル１１に連設して形成したコード接続部１２のねじ穴に螺着し、一方前記シャフト１４の先端部１４Ｂは前記ビット１９の基端部に設けたねじ穴に螺着する。又このシャフト１４の一端部から略中央部にかけてねじ部１５が刻設され、このねじ部１５は前記軸体７０の貫通孔７２に螺合し、前記第１の操作手段１０は前記軸体７０に支承されるとともに前記軸体７０と一体となって回動する［前記第１の操作手段１０は前記軸体７０を中心に可動（回動）する］。また前記シャフト１４の先端部側にはばね１７が巻装している。更に、前記ハンドル１１の把持部１１Ａには絶縁部材を被覆してある。符号１３，１８はロック用ナットである。符号１６はスライド板であり、このスライド板１６の上端面は前記第２の操作手段２０の案内部４３の下端面に衝接し、更にこのスライド板１６の下端面には前記ばね１７の一端が圧接し、この状態でこのスライド板１６は挿通した前記シャフト１４とともに水平方向に可動する（図１１参照）。
【００１７】
前記第２の操作手段２０は、メインレバー４０と、セカンドレバー６０と、メインレバー４０と前記ビット１９との間に介在させたばね１７を含んで構成してある。そして、前記メインレバー４０と前記脚体５０は一体的に形成されてメインボディ３０を構成している（図１２参照）。
【００１８】
前記メインレバー４０は、絶縁部材を被覆して形成した取手部４１と、この取手部４１の先端部側より立ち上がって形成された立上り部４２と、この立上り部４２の基端部より延設された、前記シャフト１４の可動を案内する案内部４３を備えている。この案内部４３には、前記第１の操作手段１０のシャフト１４が挿通し、前記案内部４３は前記シャフト１４が前記軸体７０を枢軸として回動する際に前記シャフト１４の動きを案内する。前記立上り部４２の上部中央には前記セカンドレバー６０を接続する接続ピン６６が挿通する挿通孔４２Ａが穿設されている（図１１及び図１２参照）。
【００１９】
前記脚体５０は、２本の脚部５１，５２と、角枠形状の接面部５３とから構成されている。前記脚部５１は、前記立上り部４２の基端部より垂設され、また他方の脚部５２は前記案内部４３の外側壁より垂設され、前記取手部４１、立上り部４２、案内部４３、脚部５１，５２，接面部５３は一体的に形成されている。符号５８は、前記接面部５３を囲成する、クッションの役割も果たす角枠形状の足場形成用カバーであり絶縁部材により形成されている。前記接面部５３と足場形成用カバー５８とで板金面に当接する足場を形成する。
【００２０】
前記セカンドレバー６０は、前記取手部４１と同様に絶縁部材を被覆して形成した取手部６１と、この取手部６１の先端部側に形成された連結部６２と、この連結部６２より延設した枠体６７を具備している。前記連結部６２は、前記メインレバー４０の前記立上り部４２を挿入する第１のくり抜き部６３を備えている。また、前記連結部６２の左右両側面には、前記メインレバー４０を接続する前記接続ピン６６を軸受けする軸受孔６２Ａ，６２Ｂが穿設されている。前記枠体６７は、前記軸体７０収容用の第２のくり抜き部６８を備えている。また、前記枠体６７の左右両側面には、前記軸体７０を構成する短軸７４Ａ，７４Ｂを軸受けする軸受孔６７Ａ，６７Ｂが互いに対向して穿設（形成）されている。前記軸受孔６２Ａ，６２Ｂと前記軸受孔６７Ａ，６７Ｂは平行に穿設されている。符号６４Ａ，６４Ｂは止めリングである。
【００２１】
前記軸体７０は、前記第２の操作手段２０の先端部に形成された前記第２のくり抜き部６８に収容されるセンタースクリュ７１と、このセンタースクリュ７１を軸支する短軸７４Ａ，７４Ｂとから構成されている。前記センタースクリュ７１は、中央に前記シャフト１４のねじ部１５が螺合する雌ねじ部が刻設（形成）されたねじ付き貫通孔７２を備え、更に左右両側に前記短軸７４Ａ，７４Ｂの先端ねじ部（ねじ付き先端部）が螺合する雌ねじ部が刻設されたねじ付き軸止孔７３Ａ，７３Ｂを備えている。前記短軸７４Ａ，７４Ｂは、前記第２の操作手段２０の枠体６７に穿設された軸受孔６７Ａ，６７Ｂに軸通（挿通）し、上述の通り、先端ねじ部（ねじ付き先端部）が前記センタースクリュ７１の軸止孔７３Ａ，７３Ｂに螺合する。
【００２２】
かくして、前記メインレバー４０と前記セカンドレバー６０とは連絡し、前記セカンドレバー６０は、前記軸受孔６２Ａ，６２Ｂ、前記シャフト挿通孔４２Ａに挿通された前記接続ピン６６を中心にして可動する。また、前記ばね１７が、前記メインボディ３０と前記ビット１９間に前記シャフト１４を巻装した状態で介在し、前記セカンドレバー６０は図５乃至図９における下方向に常時引っ張られている。
【００２３】
符号８０は、前記セカンドレバー６０を手動操作により押し下げたときに、前記セカンドレバー６０の下面部と当接して前記セカンドレバー６０が必要以上に下方へ動くのを規制するとともに、前記セカンドレバー６０の下面と当接したときの握り幅が最適な握り幅となるよう前記第２の操作手段２０の取手部４１と６１の間の握り幅を調整するためのストッパである。このストッパ８０は、前記メインレバー４０の取手部４１の近傍に設けたねじ穴４７と、このねじ穴４７に螺合し、その一端が前記セカンドレバー６０に当接するボルト８１から構成されている（図１２参照）。このボルト８１にコイルばね８２を巻装した状態で前記ボルト８１を前記メインレバー４０のねじ穴に４７に螺合させる。
【００２４】
本発明は以上のごとく構成され、構造がシンプルで部品点数が少なく軽量にして取り扱いが容易な板金用引出し具１Ａとなり、板金用引出し具１Ａをスタッド溶接機１１０と組み合わせることで足場の悪いプレスラインの板金作業においてもビットの溶着、引き出しを連続して行うことができ、この場合、板金用引出し具１Ａの前記コード接続部１２に、電源コード１００のクランプ手段１０５を取付け、電源コード１００の他端側をスタッド溶接機１１０に接続して使用する（図４参照）。
【００２５】
（板金用引出し具の使用方法）
ここで、図１３及び図１４を用いて、本発明に係る板金用引出し具１Ａの使用方法［自動車ドア３００のプレスライン３１０近辺の板金（凹部３３０の引き出し）を行う場合］を説明する。
【００２６】
本発明に係る板金用引出し具１Ａにあっては、板金用引出し具の足場は図１４の四角枠Ｓ１の表示で示される足場の位置（足場Ｓ１の全領域がプレスライン３１０の近傍に乗る）を確保することができるため、足場をしっかり確保し略均一な力で押さえることができる（従来技術の場合には、既述のように通例図３１に示されるような足場Ｓ３となる）。
【００２７】
先ず、ストッパ８０のボルト８１螺合状態の深浅を加減し、作業者にとって最適の握り幅にセットする。次に、一方の手で第２の操作手段２０を把持し、他方の手でハンドル１１を回動させて（シャフト１４のねじ部１５と軸体７０の貫通孔７２に刻設した雌ねじ部との螺合を調整して；図６参照）、引き出しを必要とする凹部３３０の深さまでビット１９の先端を下降させる。次に、図１３及び図１４におけるプレスライン３１０の近辺であるＰ点を引き出したい場合には、シャフト１４を、軸体７０を中心にして回動させて（図７参照）Ｐ点まで移動させビット１９の先端をＰ点に溶着する。そして、メインレバー４０とセカンドレバー６０間をばね１７に抗しながらつぼめて（セカンドレバー６０をばね１７に抗しながら押し下げ可動させて）Ｐ点をゆっくりと引き上げる。板金面が平滑化したことを確認し、その後ハンドル１１を回動させ（図６参照）ビット先端と板金面の溶着を解く。更に、足場がそのままでも、シャフト１４を、軸体７０を中心にして可動し、またハンドル１１を回動させながら他のポイントに移動し、上記と同様の操作を行うことにより、凹部３３０における複数のポイントの引き出しを行うことが可能である。
【００２８】
また、自動車ドア３００の端部３２０近辺の板金（凹部３４０の引き出し）を行う場合も、板金用引出し具１Ａの足場は図１４の四角枠Ｓ２の表示で示される足場の位置（足場Ｓ２の全領域が端部３２０の近傍に乗る）を確保することができるため、足場をしっかり確保し略均一な力で押さえることができる（従来技術の場合には、既述のように通例図３１に示されるような足場Ｓ４となる）。
【００２９】
（実施例２）
以上の説明では脚体の接面部及び絶縁部材を角枠形状に形成したものを示したが、図１５乃至図１７に示すように板金用引出し具１Ｂの接面部１５３を丸枠形状に形成し、絶縁部材により形成された足場形成用カバー１５８も同様に丸枠形状に形成してもよい。この実施例によれば、丸い凹状の傷を修復する際に、足場に均一の力を加えながら迅速に板金面を平滑化できる。なお、図１５乃至図１７において、実施例１と同一の符号は同一の部材を示す。
【００３０】
（実施例３）
更に、図１８乃至図２３に示すように、板金用引出し具１Ｃにおける脚体２５０の一方の脚部２５２を途中より分岐させ、接面部２５３をＵ字状形状に形成し、絶縁部材により形成された足場形成用カバー２５８を同様にＵ字状形状に形成してもよい。この実施例では、接面部２５３及び足場形成用カバー２５８がＵ字状形状に形成されているのでプレスライン３１０近辺の引出しを行う場合でもＵ字状形状の切欠部（開口部）２５４近傍まで引出しが可能となる。また、この脚体２５０を用いた場合には、図２３に示すようにプレスライン３１０の根元Ｒの引出しを簡単に行えるとともに、図２４乃至図２６に示すような長い溝傷や引っかき傷といったライン状の傷３６０の修復を行う場合でも脚部の足場の移動を必要最小限（図２４及び図２５に示す程度のライン状の傷の場合には足場の移動を２度行うだけでライン状の傷の引出しが済む）にしてその間連続作業によってライン状の傷の引出しを行うことが可能となる。なお、図１８乃至図２６において、実施例１と同一の符号は同一の部材を示す。
【００３１】
【発明の効果】
本発明は以上の如く構成され、本発明によれば次の効果を奏する。
（１）押さえたい場所を脚体で押さえ足場を位置決めしたまま操作手段を回動させてビットを引出したい板金面の複数のポイントに自由に動かして使用できる板金用引出し具が得られる。
（２）自動車ボディに形成されたプレスラインの近辺（上段部）や根元、あるいは自動車ドアの端部のように板金作業が難しくかつ時間のかかる部位の場合でも、板金作業の際に脚部の位置に制約されることなく（脚部の位置決めに煩わされることなく）、足場をしっかり確保しながら引出したいポイントを自由に引くことができる板金用引出し具が得られる。
（３）板金面の引出し箇所が長い溝傷（凹部が鋭角で長く続く傷）や引っかき傷といったライン状の傷のような場合でも足場の位置を一旦セットすれば足場の移動を必要最小限にしてその間連続作業による傷の引出しが可能となり、作業時間が短縮できて効率の良い板金作業が行える板金用引出し具が得られる。
（４）構造がシンプルで部品点数が少なく軽量にして取り扱いが容易な板金用引出し具が得られる。

When it is in the vicinity of the end portion 320 of the door 300, the leg portions 491, 492 are in a normal state (the leg portions 491, 492) even if the legs 491, 492 of the sheet metal drawer 401 are set and the point to be pulled out is pulled. When the portions 491 and 492 are set to the armbands 433A and 433B in a balanced manner in a bilaterally balanced manner), the contact surface member 493 protrudes from the press line 310 and the end 320 (see FIG. 31) (refer to the position of the scaffold shown by the display of the 31 square frames S3, S4), the contact surface member 493 can secure the scaffold firmly and cannot be pressed with a substantially uniform force. Therefore, the drawing work in the vicinity of the press line 310 and the vicinity of the end portion 320 cannot be performed quickly and reliably [In order to draw the point P or Q to be pulled out (see FIGS. 30 to 32), first, a sheet metal drawing tool is used. The positions of the main body 401 and the legs 491, 492 are shifted by 90 degrees from the state shown in FIG. 30, and the thumb screws 496, 497 are further loosened to temporarily move the positions of the legs 491, 492 to the left as shown in FIG. It is necessary to position the scaffolds of the legs 491 and 492, and then tighten the thumbscrews 496 and 497 to reset the contact member 493 to a desired position.
(2) Also, for example, when the concave portion that is the sheet metal surface is at the root R (see FIG. 35) of the press line 310 of the automobile door, the leg portion of the sheet metal drawer 401 is shown in FIGS. Instead of the legs 591 and 592 as shown, the base R of the press line 310 cannot be pulled out even if the legs 591 and 592 are put on the press line 310 (see FIG. 35) (this point, the main body of the drawer 401 and Even if the positions of the leg portions 591 and 592 are changed by 90 degrees, one of the leg portions 591 and 592 is obstructed by the root R of the press line 310 so that the root R of the push line 310 cannot be pulled out.
(3) In the case of a line-shaped scratch 360 such as a groove scratch with a long lead-out portion (a scratch having a long sharp concave portion) or a scratch, each time it is repaired, it is in the leg of the sheet metal drawer 401 each time it is repaired. It is necessary to move and set the position of the scaffold to perform the drawing work (see FIGS. 36 and 37), and the drawing work takes time and the working efficiency is poor;
