Description

【０００１】
【発明の属する技術分野】
本発明は、建設工事の現場における各壁面や部材の固定又は機械装置の組立や部品の固定に用いるボルトやナット等の締結具を締め付け、又は取り外すための締結具締付機に係り、特にボルトやナット等の大小に関係なく種々の締結具を取り扱うことができる締結具締付機アタッチメント及び締結具締付機に関するものである。
【０００２】
【従来の技術】
ビル建築現場等にあっては、コンクリート打込の前に骨材となる鉄筋を配設した後、焼きなました鋼線からなる針金（結束線）を用いてこの鉄筋間の所定箇所を結束している。従来、この結束線は、図７に示すように、例えば縦横に配設した鉄筋５１，５２の交叉部に、略Ｕ字型に曲げ形成した針金等の結束線５３を、開いた端部を作業員が手持ちし、ループした端部を鉄筋５１，５２の交叉部をくぐらせて上に上げ、交叉部の上で両者を捻り回して結束し、開いた端部をフック等の工具で鉄筋５１，５２側へ曲げたのち、コンクリート打設をしている。
【０００３】
一方、建築現場では、各建材を固定するためのナット又はボルトをスパナーやドライバー等の締結用の工具で締め付けていた。また、多数のナット又はボルト等を短時間で締め付けるときは、電動ドライバーにソケットを取り付けてナット等を締め付けていた。
【０００４】
【発明が解決しようとする課題】
しかし、上記従来の針金（結束線）５３を用いてこの鉄筋５１，５２間の所定箇所を結束する方法は、大変な労力を必要とするものであるために作業効率が低下し易いという問題を有していた。特に、夏の炎天下では、作業者が疲労しやすいため、同じ締付力で均一に鉄筋５１，５２の交叉部に結束線５３を締め付けられないことがあった。
【０００５】
また、従来の締結用の工具では、ねじ、ボルト又はナット等の締結具の外径又は形状にあったソケットをドライバーに取り付けて締め付けるものであるために、異なる大きさや種類の締結具については、その都度ソケットを交換しなければならず、非常に煩雑になりやすいという問題を有していた。
【０００６】
本発明は、かかる問題点を解決するために創案されたものである。すなわち、本発明の目的は、締結具を挟持する部分を嘴状に形成することで、ボルトやナットの大小に関係なく種々の締結具を容易に挟持できると共に、この締結具を挟持した状態で回転させ、容易かつ確実に締め付け、又は取り外すことができる締結具締付機アタッチメント及び締結具締付機を提供することにある。
【０００７】
【課題を解決するための手段】
本発明は、ボルトやナット等の締結具（Ｆ）を挟持する２本の挟持部（２，３）を嘴状に開閉自在に構成した嘴部（４）と、該嘴部（４）の先端（２ｃ，３ｃ）を、レバー（５）の操作により開閉させる締付本体部（６）と、前記嘴部（４）を回転させる電動ドライバー（Ｄ）の回転部（８）に着脱自在に連結する連結機構部（９）と、を備え、前記締付本体部（６）は、筒体（１２）内の先端側に、前記嘴部（４）の挟持部（２，３）を軸支し、嘴部（４）の中間部（２ｂ，３ｂ）側へ向けて開いている両挟持部（２，３）を閉じるように前後動する軸支部（１３）を内装し、前記筒体（１２）の外側に前記軸支部（１３）を前後移動させるレバー（５）を連結リンク（５ａ）を介して取り付けた、ことを特徴とする締結具締付機アタッチメントを提供する。
【０００８】
ここで、前記嘴部（４）は、２本の略へ字形状に形成した挟持部（２，３）を、その後端部（２ａ，３ａ）を軸支部（１３）で軸支して嘴状に組み合わせ、該挟持部（２ｃ，３ｃ）の中間部（２ｂ，３ｂ）それぞれに、略Ｙ字状の連結作動リンク（１０）の両先端部（１０ａ，１０ａ）を取り付け、前記挟持部（２ｃ，３ｃ）の軸支部（１３）を、前記挟持部（２，３）の後方へ移動させることにより挟持部（２，３）の各先端（２ｃ，３ｃ）が開き、該挟持部（２，３）の軸支部（１３）を前方へ押圧することにより挟持部（２，３）の各先端（２ｃ，３ｃ）が閉じるように構成したものである。
【０００９】
また本発明は、ボルトやナット等の締結具（Ｆ）を挟持する２本の挟持部（２，３）を嘴状に開閉自在に構成した嘴部（４）と、該嘴部（４）の先端（２ｃ，３ｃ）を、レバー（５）の操作により開閉させる締付本体部（６）と、前記嘴部（４）を回転させる電動ドライバー（Ｄ）の回転部（８）に着脱自在に連結する連結機構部（９）と、を備え、前記締付本体部（６）は、前記嘴部（４）の挟持部（２，３）の軸支部（１３）側から嘴部（４）の中間部（２ｂ，３ｂ）側へ向けて開いている両挟持部（２，３）を閉じるように前後動する円形状に開けた開度調整リング（２４）を前後移動可能に取り付け、該開度調整リング（２４）を前後移動させるレバー（５）を連結リンク（５ａ）を介して取り付けた、ことを特徴とする締結具締付機アタッチメントを提供する。
【００１０】
ここで前記開度調整リング（２４）と前記嘴部（４）の挟持部（２，３）との接触面にベアリングを介在させることが好ましい。前記連結機構部（９）は、前記電動ドライバー（Ｄ）の回転部（８）と係合する開口を有するものである。
【００１１】
前記開度調整リング（２４）と前記嘴部（４）の挟持部（２）との接触面にベアリングを介在させることが好ましい。前記連結機構部（９）は、前記電動ドライバー（Ｄ）の回転部（８）と係合する開口を有するものである。
【００１２】
前記嘴部（４）の内部に、該嘴部（４）を回転させる駆動部と直結する回転軸となる連結作動リンク（１５）に棒状締付具（２２）を着脱自在に取り付けることができる。
【００１３】
上記構成の締結具締付機アタッチメントでは、連結機構部（９）を介して電動ドライバーＤに連結する。この状態で締付本体部（６）のレバー（５）を前方へ押圧し、嘴部（４）の挟持部（２，３）でボルト等の締結具（Ｆ）を挟み、そのレバー（５）を押圧した状態で電動ドライバー（Ｄ）のトリガー（１７）を引き、モータの回転動作を連結作動リンク（１０）の後部軸（１０ｂ）から伝達して嘴部（４）を回転させる。そこで、嘴部（４）は締結具（Ｆ）を挟持した状態で回転させ、この締結具（Ｆ）を容易かつ確実に締め付けることができる。一方、電動ドライバー（Ｄ）の回転方向を逆転させれば、締結具（Ｆ）を取り外すことができる。
【００１４】
特に、締結具（Ｆ）を挟持する部分が嘴部（４）が挟持部（２，３）の各先端（２ｃ，３ｃ）が嘴状に開くように構成したものであるため、ボルトやナットの大小に関係なく種々の締結具（Ｆ）を挟持できる。更に、この嘴部（４）は、針金のようなものでも鉄筋間に対しても回転して結束することができる。
【００１５】
また本発明は、ボルトやナット等の締結具（Ｆ）を挟持する２本の挟持部（２，３）を嘴状に開閉自在に構成した嘴部（４）と、該嘴部（４）の先端（２ｃ，３ｃ）を、レバー（５）の操作により開閉させる締付本体部（６）と、前記嘴部（４）を回転させる電動ドライバー（Ｄ）の回転部（８）に着脱自在に連結する連結機構部（９）と、前記嘴部（４）を回転させる駆動部と、該駆動部を担持すると共にトリガー（１７）を配置したグリップ（２６）と、を備え、前記締付本体部（６）は、筒体（１２）内の先端側に、前記嘴部（４）の挟持部（２，３）を軸支し、嘴部（４）の中間部（２ｂ，３ｂ）側へ向けて開いている両挟持部（２，３）を閉じるように前後動する軸支部（１３）を内装し、前記筒体（１２）の外側に前記軸支部（１３）を前後移動させるレバー（５）を連結リンク（５ａ）を介して取り付けた、ことを特徴とする締結具締付機を提供する。
【００１６】
さらに本発明は、ボルトやナット等の締結具（Ｆ）を挟持する２本の挟持部（２，３）を嘴状に開閉自在に構成した嘴部（４）と、該嘴部（４）の先端（２ｃ，３ｃ）を、レバー（５）の操作により開閉させる締付本体部（６）と、前記嘴部（４）を回転させる電動ドライバー（Ｄ）の回転部（８）に着脱自在に連結する連結機構部（９）と、前記嘴部（４）を回転させる駆動部と、該駆動部を担持すると共にトリガー（１７）を配置したグリップ（２６）と、を備え、前記締付本体部（６）は、前記嘴部（４）の挟持部（２，３）の軸支部（１３）側から嘴部（４）の中間部（２ｂ，３ｂ）側へ向けて開いている両挟持部（２，３）を閉じるように前後動する円形状に開けた開度調整リング（２４）を前後移動可能に取り付け、該開度調整リング（２４）を前後移動させるレバー（５）を連結リンク（５ａ）を介して取り付けた、ことを特徴とする締結具締付機を提供する。
【００１７】
上記構成の締結具締付機では、1台の締結具締付機（１）でボルトやナットの大小に関係なく種々の締結具（Ｆ）を容易かつ確実に挟持できる。そこで、作業現場に多種類の工具、又は電動ドリルでも多数のソケットを持ち込む必要がなくなる。
【００１８】
【発明の実施の形態】
以下、本発明の好ましい実施の形態を図面を参照して説明する。
図１は本発明の締結具締付機アタッチメントの第一の実施の形態を示す一部切り欠いた正面図である。
本発明の第一の実施の形態の締結具締付機アタッチメント１は、ボルトやナット等の締結具Ｆを挟持する２本の挟持部２，３を開閉自在に構成した嘴部４と、この嘴部４の先端を、レバー５操作により開閉させる締付本体部６と、嘴部４を回転させる伝動部材７を電動ドライバーＤの回転部８に着脱自在に連結する連結機構部９と、を備えたものである。
【００１９】
嘴部４は、ボルトやナット等の締結具Ｆを挟持する略へ字形状に形成した挟持部２，３を、その後端部２ａ，３ａを軸支して嘴状に組み合わせたものである。この挟持部２，３の中間部２ｂ，３ｂそれぞれに、略Ｙ字状の連結作動リンク１０の両先端部１０ａ，１０ａを取り付けてある。軸支部１３を後方へ引くことにより、挟持部２，３の各先端２ｃ，３ｃが開き、軸支部１３を押圧することにより挟持部２，３の各先端２ｃ，３ｃが閉じるように構成したものである。この連結作動リンク１０の後部軸１０ｂは、後述するように、電動ドライバーＤの回転動作を嘴部４に伝達する伝動部材７（回転軸）としての機能を併せ持つ。
【００２０】
この嘴部４は、ボルトやナット等の締結具Ｆの頭部を挟持部２，３の先端２ｃ，３ｃで挟み易くするために、この先端２ｃ，３ｃに、締結具Ｆの頭部に接する面側に滑り止めのギャザー１１加工してある。また、略へ字形状に形成した挟持部２，３の中間部２ｂ，３ｂにおける曲折角度は、ここで挟む締結具Ｆの頭部の外径に合わせて設計変更し得る。
【００２１】
締付本体部６は、筒体１２内の先端側に、嘴部４の挟持部２，３の軸支部１３を前後移動可能に取り付けたものである。この軸支部１３は、筒体１２内の先端側において回転可能になるように、中心に開口を有するカップ内にベアリングを介して円滑に回転するように支持してある。また、筒体１２内において軸支部１３をカップと共に常時前方に押圧するコイルばね等の弾性部材１４を内装してある。この弾性部材１４は、カップと共に軸支部１３を筒体１２内の前方に押圧する。このカップは、筒体１２外に設けたレバー５を連結リンク５ａを介して前後動するようになっている。
【００２２】
締付本体部６におけるレバー５を図示上のＡ方向に引っ張ると、嘴部４の挟持部２，３の軸支部１３も同時に引っ張られる。連結作動リンク１０の位置は変化しないので挟持部２，３の各先端が開く。逆に、レバー５を元に戻すと、挟持部２，３の各先端が閉じる。
【００２３】
連結機構部９は、電動ドライバーＤの回転部８と締付本体部６内を貫通させた連結作動リンク１０の後部軸１０ｂとを連結する部分である。本発明の締結具締付機アタッチメント１は、このように電動ドライバーＤに容易に着脱自在に連結するようになっている。
【００２４】
このように構成した締結具締付機アタッチメント１を電動ドライバーＤに連結すれば、締付本体部６のレバー５をＢ方向に押圧し、嘴部４の挟持部２，３でボルトＦを挟み、そのレバー５をＢ方向に押圧した状態、即ちボルトＦを挟んだ状態で電動ドライバーＤのトリガー（スイッチ）１７を引く。このとき、電動ドライバーＤのモータが回転し、その回転動作を連結作動リンク１０の後部軸１０ｂから伝達して嘴部４を回転させる。そこで、嘴部４はこのボルトＦを挟持した状態で回転し、容易かつ確実に締め付けることができる。一方、電動ドライバーＤの回転方向を逆転させれば、ボルトＦを取り外すことができる。
【００２５】
本発明の締結具締付機アタッチメント１では、締結具Ｆを挟持する部分が嘴部４が嘴状に挟持部２，３の各先端２ｃ，３ｃが開くように構成したものであるため、ボルトやナットの大小に関係なく種々の締結具Ｆを挟持できるだけではなく、針金のような細いものでも挟持することができる。
【００２６】
図２は第一の実施の形態の変形例を示す一部切り欠いた斜視図である。図３は嘴部と締付本体部との分解斜視図である。
嘴部４の挟持部２，３の各先端２ｃ，３ｃを閉じるときに、締付本体部６におけるレバー５の可動方向は前方方向（図１のＢ方向）に限定されない。図２に示すように、レバー５を引っ張る（図２のＣ方向）と嘴部４の挟持部２，３の各先端２ｃ，３ｃを閉じるように構成することができる。この締付本体部６では、筒体１２内の先端側において、嘴部４の挟持部２，３の軸支部１３を回転可能に取り付ける。同じく、筒体１２内に、中心に開口１８を有し、この開口１８から回転軸１９を貫通させる作動管２０を取り付けた作動板２１を内装する。この作動板２１と軸支部１３との間には弾性部材１４を内装してある。
【００２７】
この締付本体部６におけるレバー５は、図２に示すように、後方へ引っ張る（図２のＣ方向）と、嘴部４の挟持部２，３の軸支部１３と作動板２１も連結作動リンク１０と共に引っ張られる。そこで、挟持部２，３の各先端２ｃ，３ｃが閉じる。逆に、レバー５を元に戻すと、挟持部２，３の各先端２ｃ，３ｃが開く。
【００２８】
また、嘴部４の内部には、この嘴部４を回転させる駆動部と直結する回転軸となる連結作動リンク１０にプラスドライバー又はマイナスドライバー等の棒状締付具２２を着脱自在に取り付けることができる。このように構成すれば、ねじ又はボルトの頭部は嘴部４の各先端２ｃ，３ｃで挟み、揺れない上体で棒状締付具２２で確実に締結することができる。
【００２９】
本発明の締結具締付機アタッチメント１は、電動ドライバーＤに着脱自在に連結し得るように構成したものである。そこで、ナットＦを専門に締め付けるときに使用するときは、図３に示すように、嘴部４が嘴状に挟持部２，３の各先端２ｃ，３ｃがナットＦを容易に締め付けられるように樋状の挟持部２，３を設けたものである。この嘴部４の挟持部２，３の形状は締結具Ｆの頭部の形状に応じて種々変更することができる。
【００３０】
図４は本発明の締結具締付機アタッチメントの第二の実施の形態を示す正面図である。図５は嘴部を示す分解斜視図である。
第二の実施の形態の締結具締付機アタッチメント１は、嘴部４の挟持部２，３を包むように構成した２個の半カップ状の外カバー２３，２３をその一端で開閉可能に取り付け、各可動部２３ａ，２３ａに、略Ｙ字状の連結作動リンク１０の両先端部１０ａ，１０ａを取り付けてある。この連結作動リンク１０の後部軸１０ｂを略し字形状に曲折し、後部軸１０ｂの一端を締付本体部６に取り付け、その一端に連結したレバー５で作動するようになっている。図示例ではレバー５を引くと連結作動リンク１０の両先端部１０ａ，１０ａが開き、挟持部２，３の各先端２ｃ，３ｃが開き、逆に、レバー５を押圧すると連結作動リンク１０の両先端部１０ａ，１０ａが閉じ、挟持部２，３の各先端２ｃ，３ｃが閉じるように構成したものである。
【００３１】
第二の実施の形態の締結具締付機アタッチメント１では、外カバー２３，２３内で嘴部４の挟持部２，３が閉じた状態で回転するようになっている。なお、外カバー２３，２３と嘴部４の挟持部２，３との接触面にベアリングを介在させて、円滑に嘴部４が回転するようになっている。
【００３２】
図６は本発明の締結具締付機アタッチメントの第三の実施の形態を示す一部切り欠いた正面図である。
第三の実施の形態の本発明の締結具締付機アタッチメント１は、締付本体部６が筒体１２内に、嘴部４の略Ｓ字形状に形成した挟持部２，３の後端部２ａ，３ａを閉じるように前後動する円形状に開けた開度調整リング２４を前後移動可能に取り付けたものである。この開度調整リング２４は筒体１２の外側に取り付けたレバー５により図示例ではレバー５を引くと開度調整リング２４が挟持部２，３を閉じ、各先端２ｃ，３ｃが閉じ、逆に、レバー５を押圧すると開度調整リング２４が挟持部２，３から離れ、挟持部２，３に挟んだ弾性部材２５の弾性力により先端２ｃ，３ｃが開くように構成したものである。
【００３３】
第三の実施の形態の締結具締付機アタッチメント１では、開度調整リング２４で嘴部４の挟持部２，３が閉じた状態で回転するようになっている。なお、開度調整リング２４と嘴部４の挟持部２，３との接触面にベアリングを介在させて、円滑に嘴部４が回転するようになっている。
【００３４】
本発明は上述した発明の実施の形態では、締結具締付機アタッチメント１を電動ドライバーＤに着脱自在に連結し得るように構成したものを説明している。しかし、上述したような構成の嘴部４と、この嘴部４の先端２ｃ，３ｃをレバー５の操作により開閉させる締付本体部６と、嘴部４を回転させる駆動部を担持すると共にトリガー１７を配置したグリップ２６と一体的に構成した締結具締付機とすることは勿論可能である。
【００３５】
なお、本発明は上述した発明の実施の形態に限定されず、ボルトやナットの大小に関係なく種々の締結具Ｆを挟持でき、この締結具Ｆを挟持した状態で容易に回転させる構成にすることにより、ボルトやナットの大小に関係なく種々の締結具Ｆを挟持できる締付機であれば、図示したような構成に限定されず、本発明の要旨を逸脱しない範囲で種々変更できることは勿論である。
【００３６】
更に、本発明の締結具締付機アタッチメント又は締結具締付機は、上述し建設現場や機械装置の組立に限定されず、医療手術の差煮の際に患部を挟み、その状態で回転させる作業に応用することも可能である。
【００３７】
【発明の効果】
本発明の締結具締付機アタッチメントは、ボルトやナットの大小に関係なく種々の締結具を挟持できると共に、この締結具を挟持した状態で回転させ、容易かつ確実に締め付け、又は取り外すことができる。特に、締結具を挟持する部分が嘴部が嘴状の各先端が開くように構成したものであるため、ボルトやナットの大小に関係なく種々の締結具を挟持できる。更に、従来では不可能であった針金のような細いものも巻き付けることができる。
【００３８】
また、締結具締付機は、1台の締結具締付機でボルトやナットの大小に関係なく種々の締結具を挟持できるので、作業現場に多数の工具持ち込む必要がない、等の効果がある。
