可動掴持体部材支持部68は、掴線器本体部材12の後方の高さ方向における下部であって、連結部材案内部26より高さ方向における上方に位置している。
作動部材14は、正面視略三角形状で、前方の上部の内角部分に、支軸70を挿入する掴線器本体部材取付孔60が穿設され、後方の上部の内角部分に可動掴持体部材回動軸74を挿入する可動掴持体部材取付孔62が穿設され、後方の下部の内角部分に連結部材回動軸72を挿入する連結部材取付孔64が穿設されている。連結部材回動軸72および可動掴持体部材回動軸74は、支軸70と比較して、連結部材18の延びる方向である後方(右側)に位置している。
作動部材14は、線状体保持部22の下方において、線状体保持部22の下面の近傍から垂下されている。
作動部材14は、線状体Wの径が細くて線状体押さえ部24と線状体保持部22とが近づいて線状体Wを掴持したとき及び線状体Wの径が太くて線状体押さえ部24と線状体押さえ部24とが離れて線状体Wを掴持するときにおいて、連結部材18が線状体保持部22の下方から線状体保持部22の高さと同等かそれより高い位置にのび且つ中腹で連結部材案内部26に支持される長さを備えている(図25~27参照)。
可動掴持体部材16は、図5に示すように、断面形状がコの字状に形成され、前後において平行に並ぶ第1作動部材取付部92および第2作動部材取付部94を備えている。第1作動部材取付部92と第2作動部材取付部94とは、作動部材14の後部の上部に跨っている。第1作動部材取付部92には第1作動部材取付孔96が穿設され、第2作動部材取付部94には第2作動部材取付孔98が穿設されている。可動掴持体部材16は、一直線状に並列された第1作動部材取付孔96、第2作動部材取付孔98および作動部材14の可動掴持体部材取付孔62に貫挿された可動掴持体部材回動軸74によって、作動部材14に回動自在に取り付けられている。第1作動部材取付孔96、第2作動部材取付孔98および可動掴持体部材取付孔62は、同一径で、それらの孔の外周縁が平行になるように並列されている。
前記連結部材18は、長尺状の連結部材本体部80と、前記連結部材本体部80の後端に設けたリング部130とを有している。
前記リング部130は、前記線状体押さえ部24と前記線状体保持部22とが延びる方向である左右軸を含む基準平面に対して、連結部材本体部80との境界から引っ張る方向に沿う軸線に沿って側部輪郭部まで所定の角度に折り曲げられている。
前記折り曲げられた領域は、線状体Wが前記線状体押さえ部24と前記線状体保持部22との間に掴持されたとき、前記線状体押さえ部24と前記線状体保持部22とが延びる方向に沿った方向であって、連結部材を引っ張る方向に沿った位置で、かつ、前記線状体保持部22と同等又は下方の位置である。
連結部材18は、作動部材14の向こう側において(すなわち架設部24c寄りにおいて)、作動部材14の下端より、引っ張る側の上方に向けてのびている。
連結部材18は、線状体Wの径が細くて線状体押さえ部24と線状体保持部22とが近づいて線状体Wを掴持したとき及び線状体Wの径が太くて線状体押さえ部24と線状体押さえ部24とが離れて線状体Wを掴持するときにおいて、線状体保持部22の下方から線状体保持部22の高さと同等かそれより高い位置にのび且つ中腹で連結部材案内部26に支持される長さを備えている(図25~27参照)。
連結部材18の連結部材本体部80は、左側の端部が連結部材回動軸72により作動部材14に回動自在に取り付けられ、且つ、中間が連結部材案内部26のガイド孔28に支持されている。
連結部材18の連結部材本体部80は、その下端縁が連結部材案内部26のガイド孔28の下端に摺動自在に支持されている。
リング部130は、略卵形であり、連結部材本体部80側の領域が細く、連結部材本体部80側とは反対側の自由端領域が膨らんでいる。
下輪郭部分134は、自由端側である側輪郭部分136が、連結部材本体部80の下端縁よりやや下方に向けて下がっている。
引張力がかかる基点tは、折り曲げ領域100の位置より上方に位置するように形成されている。
この構成によって、掴線器10が張線装置のフック等を引っ掛けて張線装置で引っ張られたとき、線状体Wの延びる方向と略々並行に引っ張ることができ、掴線器10を傾けたり、線状体Wを曲げ・回転させたりすることなく、引っ張ることができる。それは、線状体Wの径の大きさが変わっても、ほぼ同様である。
線状体Wを掴線器10により掴むとき、リング部130の上側の領域が手前側から向こう側に向けて折り曲げられているので、掴線器10を把握部500にて把握して線状体Wに向けて持ち上げて線状体Wに近づけても、線状体Wがリング部130に干渉することなく、線状体押さえ部24と線状体保持部22との間に線状体Wを挟むことができる。
又、線状体Wに取り付けられた掴線器10の連結部材18のリング部130を張線器などで引っ張る側に向けて引っ張ったときも、リング部130の上側の領域が手前側から向こう側に向けて折り曲げられているので、リング部130が線状体Wに干渉されることなく引っ張ることができる。
リング部130の長手方向の中心線A2は、傾斜部分140の上側領域を形成する上輪郭部分132と下輪郭部分134の下側領域との間を通る。
折り曲げ領域100は、略々直線状であり、連結部材本体部80の軸線A1と斜交しており、下輪郭部分134の下側領域の引張り穴144側に続いている。
そして、折り曲げ領域100は、リング部130の後ろ側領域の下方に続いており、リング部130の後ろ側領域の下輪郭部分134の下側領域との境界の近傍に続き、リング部130の後ろ側領域を折り曲げられている。
折り曲げ領域100は、リング部130の中心線A2に近い位置において、該中心線A2と略々平行又はそれに近いすなわち該中心線A2とのなす角度が小さい角度でのびている。
折り曲げ領域100は、線状体Wの径が短い細い線状体Wであっても、又、線状体Wの径が長い太い線状体Wであっても、線状体Wののびる方向と略々平行であって、すなわち、線状体押さえ部24及び線状体保持部22ののびる方向と略々平行で又は線状体Wののびる方向に近いすなわちWののびる方向とのなす角度が小さい角度でのびるように形成されている。
リング部130の折り曲げ領域100は、線状体Wの径が細くて線状体押さえ部24と線状体保持部22とが近づいて線状体Wを掴持したとき及び線状体Wの径が太くて線状体押さえ部24と線状体押さえ部24とが離れて線状体Wを掴持するときにおいて、(正面視において)支軸70及び可動掴持体部材回動軸74の高さと略々同じ位置又はそれより僅かに高い若しくは僅かに低い位置に位置するように形成されている(図25~27参照)。
この発明の実施の形態においては、所定の角度、すなわち、固定掴持体部20の線状体押さえ部24と可動掴持体部材16の線状体保持部22とが延びる方向である左右軸を含む基準平面Pyzとリング部130の引張り穴144の上側の領域を含む傾斜部分140を通る平面Pxzとのなす角度は、25度であり、所定の角度は、15~40度の範囲である。
所定の角度が15度未満であると、線状体Wに干渉する可能性が高まり、又、所定の角度が40度を超えると張線装置のフックもしくはベルトを引っ掛けて張線装置で引っ張るときに、線状体Wの延びる方向と略々平行に引っ張ることができにくくなる。
これにより、リング部130が線状体Wに確実に干渉することなく、線状体Wに近接する。従って、リング部130の中心線A2と線状体Wの中心との位置が大きく離れることはない。つまり、リング部130は、引張り穴144に取り付けられた張線装置のフックもしくはベルトを引っ張るとき、線状体Wの中心に近い位置において引っ張られるので、掴線器10が傾くことなく、また、線状体Wが屈曲することなく、線状体Wを引っ張ることができる。この結果、屈曲に起因する線状体Wの表面に生じる損傷などが抑制される。
この発明にかかる掴線器10は、人が片手で掴線器10を把持するための把握部500を備える。
把握部500は、主として、連結部材案内部26と連結部材本体部80と親指掛け部120とによって構成されている。
掴線器本体部材12は、向こう側(背面側)に連結部材案内部26を形成された領域及び連結部材案内部26の上部の近傍において、人差し指を宛がう、人差指当て部152を備える。
掴線器本体部材12の連結部材案内部26は、手前側(正面側)に連結部材18の向こう側(背面側)から回してこられた中指の腹を宛がう領域に中指当て部154を備える。
掴線器本体部材12は、前方すなわち押し戻す側の面に中指の付け根の近傍を宛がう握り部156を備える。
握り部156は、宛てがわれた中指により後方(引っ張る側)に引かれる。
連結部材案内部26は、中指当て部154を構成する本体部26aとは反対側すなわちガイド孔28を挟んだ向こう側の本体部26bが人差指当て部152を構成しており、人差指当て部152は、線状体押さえ部24の架設部24cの下方において垂下されている。
本体部26aと本体部26bとの間に形成されたガイド孔28は、連結部材18の連結部材本体部80が貫挿されている。
指当接部158は、可動掴持体部材支持部68より後方にのびる水平面を有し、連結部材案内部26の前方の面と交差する。
親指掛け部120は、リング部130より前方にあり、且つ、連結部材案内部26は、親指掛け部120より前方に有る。
親指掛け部120及び連結部材案内部26は、線状体Wを挟持する線状体押さえ部24と線状体保持部22との後方部分より後方側であるが、リング部130より前方側である。
そして、親指掛け部120及び連結部材案内部26は、線状体押さえ部24と線状体保持部22に近い位置に形成されているために、重量のバランスが比較的良く、掴線器10を連結部材案内部26と親指掛け部120とに跨って手で持ち、掴線器10を持ち上げて線状体Wに引っ掛け易い。
この発明の実施の形態においては、連結部材案内部26と親指掛け部120との間の長さL1は、リング部130を後方に引いた状態において、親指掛け部120に親指を引っ掛け、連結部材案内部26の前方端に人差指、中指及び薬指を引っ掛けて把握するために、親指と人差し指との間の長さL2が3~6cmとすると、それに対応する長さに形成されている。
前記連結部材18の掴線器を人の手で握ったときに親指が掛かる親指掛け部120は、連結部材本体部80のリング部130側であって、固定掴持体部20の架設部24c側の領域に形成されている。
前記リング部130は、前記線状体押さえ部24と前記線状体保持部22とが延びる方向である左右軸を含む基準平面に対して、リング部130と連結部材本体部80との境界から引っ張る方向に沿う軸線に沿って側部輪郭部まで所定の角度に折り曲げられている。
前記折り曲げられた領域は、線状体Wが前記線状体押さえ部24と前記線状体保持部22との間に掴持されたとき、前記線状体押さえ部24と前記線状体保持部22とが延びる方向に沿った方向であって、レバー部材を引っ張る方向に沿った位置で、かつ、前記線状体保持部22と同等又は下方の位置である。
かかる折り曲げられた領域の折り曲げは、鍛造で形成することがあるが、該折り曲げ時に親指掛け部120も同時に鍛造によって折り曲げられる。そこで、親指掛け部120の最上端は、折り曲げられた領域を折り曲げのできる位置において、折り曲げの高さと同じかそれよりも若干低い形状となる。
(f)カバー部
カバー部材19は、正面視略四角形状であり、掴線器本体部材12にカバー部材回動軸210により回動可能に取り付けられている。カバー部材19は、固定掴持体部20の線状体押さえ部24および可動掴持体部材16の線状体保持部22によって掴持された線状体Wが掴線器10から外れるのを防止するためのものである。カバー部材19は、固定掴持体部20の線状体押さえ部24および可動掴持体部材16の線状体保持部22の延びる方向である左右軸を含む基準平面Pyzに平行に形成されている。

そのとき、人の指の付け根に近い手の平に連結部材18(向こう側面)を当て、中指、薬指及び小指を折り曲げてそれらの指の腹を連結部材18の手前側面に当て、母指球を連結部材18の向こう側面に当接させる。
親指は、曲げられて親指掛け部120に親指の人差指側の面を掛ける。
人差指は、伸ばして連結部材案内部26の向こう側面及び掴線器本体部材12の向こう側面に当接させる。
中指は、曲げられて連結部材案内部26の手前側(正面側)に、指の腹を添える。
この実施の形態である掴線器1000は、図1図示実施の形態である掴線器10とは、連結部材18の構成が異なる。
前記掴線器本体部材12に支軸70により揺動可能に取り付けられた作動部材14と、
前記作動部材14の揺動により、前記固定掴持体部20の線状体押さえ部24に向けて揺動する、線状体保持部22を有する可動掴持体部材16と、
前記作動部材14に回動軸により連結され、作動部材14を揺動させる連結部材18と、を備える掴線器1000である。
前記連結部材18は、長尺状の連結部材本体部80と、前記連結部材本体部80の後端に設けたリング部130とを有し、前記リング部130は、前記線状体押さえ部24と前記線状体保持部22とが延びる方向である左右軸を含む基準平面に対して、連結部材本体部80との境界から引っ張る方向に沿う軸線に沿って側部輪郭部まで所定の角度に折り曲げられている。
前記折り曲げられた領域は、線状体Wが前記線状体押さえ部24と前記線状体保持部22との間に掴持されたとき、前記線状体押さえ部24と前記線状体保持部22とが延びる方向に沿った方向であって、連結部材を引っ張る方向に沿った位置で、かつ、前記線状体保持部22と同等又は下方の位置である。
重心に近い領域及び/又は連結部材を引っ張る側に掴線器1000を把握するための把握部1500が備えられており、前記把握部1500は、連結部材18の連結部材本体部80と、掴線器本体部材12の引っ張る側において下方に向けて突設された連結部材案内部26とにより構成され、該把握部1500を指及び/又は手の平で把握するように形成されている。
カバー部材19を備えた掴線器1000の重心Gは、連結部材18が押し戻す側に位置しているとき(第1の状態)、可動掴持体部材回動軸74の近傍に位置している。
連結部材18を(前記第1の状態より)少しだけ引っ張る側に位置しているとき(第2の状態)、カバー部材19を備えた掴線器1000の重心G1は、可動掴持体部材回動軸74より少し引っ張る側に位置している。
前記第2の状態より更に引っ張ったとき(第3の状態)、カバー部材19を備えた掴線器1000の重心G2は、前記重心G1の位置より更に引っ張る側に位置する。
カバー部材19を備えない掴線器1000の重心G3は、前記第1の状態より少し下方に位置したところに位置している。
前記連結部材18は、長尺状の連結部材本体部80と、前記連結部材本体部80の後端に設けたリング部130とを有している。
前記リング部130は、前記線状体押さえ部24と前記線状体保持部22とが延びる方向である左右軸を含む基準平面に対して、連結部材本体部80との境界から引っ張る方向に沿う軸線に沿って側部輪郭部まで所定の角度に折り曲げられている。
前記折り曲げられた領域は、線状体Wが前記線状体押さえ部24と前記線状体保持部22との間に掴持されたとき、前記線状体押さえ部24と前記線状体保持部22とが延びる方向に沿った方向であって、連結部材を引っ張る方向に沿った位置で、かつ、前記線状体保持部22と同等又は下方の位置である。
連結部材18は、作動部材14の向こう側において(すなわち架設部24c寄りにおいて)、作動部材14の下端より、引っ張る側の上方に向けてのびている。
連結部材18は、線状体Wの径が細くて線状体押さえ部24と線状体保持部22とが近づいて線状体Wを掴持したとき及び線状体Wの径が太くて線状体押さえ部24と線状体押さえ部24とが離れて線状体Wを掴持するときにおいて、線状体保持部22の下方から線状体保持部22の高さと同等かそれより高い位置にのび且つ中腹で連結部材案内部26に支持される長さを備えている(図25~27参照)。
連結部材18の連結部材本体部80は、左側の端部が連結部材回動軸72により作動部材14に回動自在に取り付けられ、且つ、中間が連結部材案内部26のガイド孔28に支持されている。
連結部材18の連結部材本体部80は、その下端縁が連結部材案内部26のガイド孔28の下端に摺動自在に支持されている。
リング部130は、略卵形であり、連結部材本体部80側の領域が細く、連結部材本体部80側とは反対側の自由端領域が膨らんでいる。
下輪郭部分134は、自由端側である側輪郭部分136が、連結部材本体部80の下端縁よりやや下方に向けて下がっている。
引張力がかかる基点tは、折り曲げ領域100の位置より上方に位置するように形成されている。
この構成によって、掴線器10が張線装置のフック等を引っ掛けて張線装置で引っ張られたとき、線状体Wの延びる方向と略々並行に引っ張ることができ、掴線器10を傾けたり、線状体Wを曲げ・回転させたりすることなく、引っ張ることができる。それは、線状体Wの径の大きさが変わっても、ほぼ同様である。
線状体Wを掴線器10により掴むとき、リング部130の上側の領域が手前側から向こう側に向けて折り曲げられているので、掴線器10を把握部500にて把握して線状体Wに向けて持ち上げて線状体Wに近づけても、線状体Wがリング部130に干渉することなく、線状体押さえ部24と線状体保持部22との間に線状体Wを挟むことができる。
又、線状体Wに取り付けられた掴線器10の連結部材18のリング部130を張線器などで引っ張る側に向けて引っ張ったときも、リング部130の上側の領域が手前側から向こう側に向けて折り曲げられているので、リング部130が線状体Wに干渉されることなく引っ張ることができる。
リング部130の長手方向の中心線A2は、傾斜部分140の上側領域を形成する上輪郭部分132と下輪郭部分134の下側領域との間を通る。
折り曲げ領域100は、略々直線状であり、連結部材本体部80の軸線A1と斜交しており、下輪郭部分134の下側領域の引張り穴144側に続いている。
そして、折り曲げ領域100は、リング部130の後ろ側領域の下方に続いており、リング部130の後ろ側領域の下輪郭部分134の下側領域との境界の近傍に続き、リング部130の後ろ側領域を折り曲げられている。
折り曲げ領域100は、リング部130の中心線A2に近い位置において、該中心線A2と略々平行又はそれに近いすなわち該中心線A2とのなす角度が小さい角度でのびている。
折り曲げ領域100は、線状体Wの径が短い細い線状体Wであっても、又、線状体Wの径が長い太い線状体Wであっても、線状体Wののびる方向と略々平行であって、すなわち、線状体押さえ部24及び線状体保持部22ののびる方向と略々平行で又は線状体Wののびる方向に近いすなわちWののびる方向とのなす角度が小さい角度でのびるように形成されている。
リング部130の折り曲げ領域100は、線状体Wの径が細くて線状体押さえ部24と線状体保持部22とが近づいて線状体Wを掴持したとき及び線状体Wの径が太くて線状体押さえ部24と線状体押さえ部24とが離れて線状体Wを掴持するときにおいて、(正面視において)支軸70及び可動掴持体部材回動軸74の高さと略々同じ位置又はそれより僅かに高い若しくは僅かに低い位置に位置するように形成されている(図25~27参照)。
この発明の実施の形態においては、所定の角度、すなわち、固定掴持体部20の線状体押さえ部24と可動掴持体部材16の線状体保持部22とが延びる方向である左右軸を含む基準平面Pyzとリング部130の引張り穴144の上側の領域を含む傾斜部分140を通る平面Pxzとのなす角度は、25度であり、所定の角度は、15~40度の範囲である。
所定の角度が15度未満であると、線状体Wに干渉する可能性が高まり、又、所定の角度が40度を超えると張線装置のフックもしくはベルトを引っ掛けて張線装置で引っ張るときに、線状体Wの延びる方向と略々平行に引っ張ることができにくくなる。
これにより、リング部130が線状体Wに確実に干渉することなく、線状体Wに近接する。従って、リング部130の中心線A2と線状体Wの中心との位置が大きく離れることはない。つまり、リング部130は、引張り穴144に取り付けられた張線装置のフックもしくはベルトを引っ張るとき、線状体Wの中心に近い位置において引っ張られるので、掴線器10が傾くことなく、また、線状体Wが屈曲することなく、線状体Wを引っ張ることができる。この結果、屈曲に起因する線状体Wの表面に生じる損傷などが抑制される。
この発明にかかる第2の実施の形態にかかる掴線器1000は、人が片手で掴線器1000を把持するための把握部1500を備える。
把握部1500は、主として、連結部材案内部26と連結部材本体部80と親指掛け部1120とによって構成されている。
掴線器本体部材12は、向こう側(背面側)に連結部材案内部26を形成された領域及び連結部材案内部26の上部の近傍において、人差し指を宛がう、人差指当て部152を備える。
掴線器本体部材12の連結部材案内部26は、手前側(正面側)に連結部材18の向こう側(背面側)から回してこられた中指の腹を宛がう、領域を備える。
掴線器本体部材12は、前方すなわち押し戻す側の面に中指の付け根の近傍を宛がう握り部156を備える。
握り部156は、宛てがわれた中指により後方(引っ張る側)に引かれる。
連結部材案内部26は、中指当て部154を構成する本体部26aとは反対側すなわちガイド孔28を挟んだ向こう側の本体部26bが人差指当て部152を構成しており、人差指当て部152は、線状体押さえ部24の架設部24cの下方において垂下されている。
本体部26aと本体部26bとの間に形成されたガイド孔28は、連結部材18の連結部材本体部80が貫挿されている。
指当接部158は、可動掴持体部材支持部68より後方にのびる水平面を有し、連結部材案内部26の前方の面と交差する。
親指掛け部1120は、リング部130より前方にあり、且つ、連結部材案内部26は、親指掛け部1120より前方に有る。
親指掛け部1120及び連結部材案内部26は、線状体Wを挟持する線状体押さえ部24と線状体保持部22との後方部分より後方側であるが、リング部130より前方側である。
そして、親指掛け部1120及び連結部材案内部26は、線状体押さえ部24と線状体保持部22に近い位置に形成されているために、重量のバランスが比較的良く、掴線器1000を連結部材案内部26と親指掛け部1120とに跨って手で持ち、掴線器1000を持ち上げて線状体Wに引っ掛け易い。
この発明の実施の形態においては、連結部材案内部26と親指掛け部1120との間の長さL1は、リング部130を後方に引いた状態において、親指掛け部1120に親指を引っ掛け、連結部材案内部26の前方端に人差指、中指及び薬指を引っ掛けて把握するために、親指と人差し指との間の長さL2が3~6cmとすると、それに対応する長さに形成されている。
前記連結部材18の掴線器を人の手で握ったときに親指が掛かる親指掛け部1120は、連結部材本体部80のリング部130側であって、固定掴持体部20の架設部24c側の領域に形成されている。
前記リング部130は、前記線状体押さえ部24と前記線状体保持部22とが延びる方向である左右軸を含む基準平面に対して、リング部130と連結部材本体部80との境界から引っ張る方向に沿う軸線に沿って側部輪郭部まで所定の角度に折り曲げられている。
前記折り曲げられた領域は、線状体Wが前記線状体押さえ部24と前記線状体保持部22との間に掴持されたとき、前記線状体押さえ部24と前記線状体保持部22とが延びる方向に沿った方向であって、レバー部材を引っ張る方向に沿った位置で、かつ、前記線状体保持部22と同等又は下方の位置である。
かかる折り曲げられた領域の折り曲げは、鍛造で形成することがある。
親指掛け部1120の最上端は、リング部130の中心線A2より低い位置であり、且つ折り曲げられた領域を折り曲げのできる位置において、折り曲げの高さと同じかそれよりも若干低い形状となる。親指掛け部1120は、リング部130の中心線A2より低い位置にあるので、掴線器1000を把握部1500にて把握して線状体Wに向けて持ち上げて線状体Wに近づけるとき及び線状体押さえ部24と線状体保持部22との間に線状体Wを挟むときにおいて、線状体Wが親指掛け部1120に掛けた親指に干渉することがない。
すなわち、本発明の技術的思想及び目的の範囲から逸脱することなく、以上説明した実施の形態に対し、機序、形状、材質、数量、位置又は配置等に関して、様々の変更を加えることができるものであり、それらは、本発明に含まれるものである。
