【０００１】
【発明の属する技術分野】
本発明は、電線、管、ホース等の線材を集束した線材束を所定位置で分岐して形成された分岐部を結束して保持する線材保持具に関するものである。
【０００２】
【従来の技術】
車両用、電気通信用、流体輸送用等に使用される電線（光ファイバを含む）、管、ホース等の線材を集束した線材束を所定位置で分岐して分岐部を形成する場合、特に、車両内に配索されるワイヤーハーネスにおいては、大量の電線を集束した電線束を所定位置で分岐して必要とする本数の電線を各種の電気、電子部品等へ配索するために多数の分岐部が形成される。この場合、その分岐部において、電線束がたるんだり、ほどけたり、外力により位置ずれや変形を生じたりしないように分岐部の電線束をテープ巻き等により結束して分岐部の形状崩れを防止し、分岐部２を所定位置に保持して固定するようにしている。
【０００３】
ところが、前記テープ巻き等による結束方法では、分岐部における電線束等の線材束の結束作業が煩雑になり、工数および時間を要して能率的でないため、線材束を所定位置で分岐して形成された分岐部を結束して保持する、例えば、図６（ａ）（ｂ）に示す線材保持具が提案されている。
【０００４】
この線材保持具１は、図６（ａ）に示すように、バンド挿入係止ブロック３と、その係止ブロック３に、自由端側がＹ字形に広がるように（例えば、特許文献２、３参照）に、又は、図示省略するが、平行に配置されるように（例えば、特許文献１、４参照）に設けられた２条の巻着バンド４とを備えて構成される。
【０００５】
そして、図６（ｂ）に示すように、各巻着バンド４を、ワイヤーハーネスを構成する電線束等の線材束を、例えば、Ｔ字形に分岐して形成された分岐部２の中央に位置する線材束２ｃを挟むようにして、その両側に位置する線材束２ａ、２ｂの外周に巻き付け、これら巻着バンド４の自由端側を前記バンド挿入係止ブロック３のバンド挿入孔５に挿入し、各巻着バンド４の両外面に設けられた係止突起その他の係止部６を、前記バンド挿入係止ブロック３のバンド挿入孔５内に設けられた弾性係止片その他の係止体７に係合して、各巻着バンド４の戻り方向への移動を拘束しつつ、バンド挿入孔５に挿通させ、これら巻着バンド４を該バンド挿入孔５の出口側から引張り出して線材束２ａ、２ｂを締め付けるようにしたものである。なお、８はバンド挿入係止ブロック３の頭部に立設され、線材保持具１を車体、電気機器等のパネル、壁等の支持部材に取り付けるための先端が矢尻状に形成されたクリップである。

【発明が解決しようとする課題】
しかしながら、従来の線材保持具１を用いて分岐部２を結束しようとすると、その２条の巻着バンド４を個別に締め付ける必要があるため、分岐部２の線材束２ａ、２ｂの締め付けがアンバランスになり易く、線材束２ａ、２ｂを均等に締め付けることが難しい。このため、一方の線材束２ａ、２ｂの不足した状態で分岐部２を結束した場合には、分岐部２が形状崩れを起こしたり、長手方向に応力が作用する方向に位置ずれを起こしたりして、分岐部２を正しい位置に保持して固定することが出来なくなる恐れがあった。
【０００８】
本発明は上記課題を解決し、分岐部の形状崩れや長手方向への位置ずれをなくし、分岐部を正しい位置に保持して固定することが出来る線材保持具を提供することを目的としている。
【０００９】
【課題を解決するための手段】
上記目的を達成するため、本発明の請求項１に記載された線材保持具は、主バンドの一端側に補助バンドが分岐して設けられ、線材束を所定位置で分岐して形成された分岐部の外周に巻回可能な可撓性の結束バンド部と、結束バンド部の主バンドと補助バンドをループ状に連結固定するバンド連結固定部とを備え、結束バンド部の主バンドとバンド連結固定部が、主バンドの自由端側に設けられた係止部と、バンド連結固定部に配設されて主バンドの自由端側が挿入されたときその係止部に係合する係止体で主バンドの戻り方向の移動を拘束するバンド挿入係止ブロックとを有する主バンド係止手段で係止され、結束バンド部の補助バンドとバンド連結固定部が補助バンド係止手段により係止される線材保持具であって、前記バンド連結固定部は、一端側にバンド挿入係止ブロックが配設され、他端側に補助バンド係止部材が配設され、前記補助バンドが二股状に分岐して設けられる分岐点と前記線材束の分岐部の中心がほぼ合致し、前記分岐部の中央に位置する線材束が前記補助バンド間の三角状スペース上に来て、かつ分岐部の両側に位置する線材束が主バンドの長手方向軸線に直交するように、結束バンド部の上に分岐部を位置決め配置し、前記バンド挿入係止ブロックに主バンドの自由端側を所定量挿入し、前記補助バンドを線材束の外周に沿って折り曲げて前記バンド連結固定部の補助バンド係止部材に係止することにより、結束バンド部とバンド連結固定部間に分岐部を挟着し、主バンドの自由端側をバンド挿入係止ブロックから引張り出して線材束を締め付けるものである。
【００１０】
このような構成によると、線材保持具の結束バンド部とバンド連結固定部間の所定位置に位置決め配置された分岐部を結束バンド部とバンド連結固定部間に挟着し、バンド連結固定部側のバンド挿入係止ブロックに挿入された結束バンド部の主バンドの自由端側をバンド挿入係止ブロックから引張り出すことにより締め付けるので、分岐部を複数箇所で同時に、且つ、均等な締付力で十分に締め付けることが可能になる。これにより、分岐部が形状崩れを起こしたり、長手方向へ位置ずれを起こしたりすることがなくなり、分岐部を正しい位置に保持して固定することが出来る。
【００１１】
本発明の請求項２に記載された線材保持具は、主バンドの一端側に補助バンドが分岐して設けられ、線材束を所定位置で分岐して形成された分岐部の外周に巻回可能な可撓性の結束バンド部と、結束バンド部の主バンドと補助バンドをループ状に連結固定するバンド連結固定部とを備え、結束バンド部の主バンドとバンド連結固定部が、主バンドの自由端側に設けられた係止部と、バンド連結固定部に配設されて主バンドの自由端側が挿入されたときその係止部に係合する係止体で主バンドの戻り方向の移動を拘束するバンド挿入係止ブロックとを有する主バンド係止手段で係止され、結束バンド部の補助バンドとバンド連結固定部が補助バンド係止手段により係止される線材保持具であって、前記バンド連結固定部は、一端側にバンド挿入係止ブロックが配設され、他端側に補助バンド係止部材が配設され、前記補助バンドが二股状に分岐して設けられる分岐点と前記線材束の分岐部の中心がほぼ合致し、前記分岐部の中央に位置する線材束が前記補助バンド間の三角状スペース上に来て、かつ分岐部の両側に位置する線材束が主バンドの長手方向軸線に直交するように、結束バンド部の上に分岐部を位置決め配置し、前記バンド挿入係止ブロックに主バンドの自由端側を所定量挿入し、前記補助バンドを線材束の外周に沿って折り曲げて前記バンド連結固定部の補助バンド係止部材に係止することにより、結束バンド部とバンド連結固定部間に分岐部を挟着し、主バンドの自由端側をバンド挿入係止ブロックから引張り出して線材束を締め付け、さらに前記補助バンド係止手段が、結束バンド部の各補助バンドの先端側とバンド連結固定部側のいずれか一方側に設けられた係止穴と他方側に設けられて前記係止穴に挿入係止される係止凸部とを組み合わせて構成されるものである。
【００１２】
このような構成によると、線材保持具を前記分岐部に装着する場合、主バンド係止手段のバンド連結固定部側のバンド挿入係止ブロックに結束バンド部の主バンドの自由端側を所定量挿入して仮係止する作業を装着作業前に予め行っておき、装着作業時には、線材保持具の結束バンド部とバンド連結固定部間の所定位置に結束すべき分岐部を位置決め配置した後、単に結束バンド部の補助バンドを分岐部を構成する線材束の外周に沿って折り曲げてバンド連結固定部に、いずれか一方の係止穴に他方の係止凸部を挿入係止することにより、結束バンド部とバンド連結固定部間に分岐部を挟着することが可能になる。従って、分岐部に線材保持具を簡単に装着することができ、線材保持具の装着作業性がより向上し、装着作業の自動化を図れるので好ましい。
【００１３】
本発明の請求項３に記載された線材保持具は、請求項２記載のものにおいて、前記バンド連結固定部の一端側に前記バンド挿入係止ブロックが配設され、その他端側に補助バンド係止部材が配設されてその補助バンド係止部材に前記係止穴又は係止凸部が設けられ、前記バンド挿入係止ブロックと前記補助バンド係止部材が可撓性アームで連結されるものである。
【００１４】
このような構成によると、分岐部に線材保持具を装着する際、バンド連結固定部が分岐部を構成する線材束の外周面に沿って容易に折れ曲がって隙間なく密着するので、分岐部を結束バンド部とバンド連結固定部間に確実に挟着することができる。また、主バンド係止手段のバンド挿入係止ブロックにおける主バンド引出し側のスペースが補助バンド係止部材で邪魔されず広くなるので、結束バンド部の主バンドの自由端側をバンド挿入係止ブロックから容易、且つ、円滑に引張り出すことができ、線材保持具の装着の作業性が向上するほか、線材束を締め付け易くなり、分岐部の結束の信頼性が向上するので好ましい。
【００１５】
【発明の実施の形態】
次に本発明の実施形態を図面に基づき詳細に説明する。図１は本発明に係る線材保持具の一実施形態を示す斜視図、図２はその構成部品を示すもので、（ａ）は結束バンド部の斜視図、（ｂ）はバンド連結固定部の斜視図である。
【００１６】
本発明の線材保持具１１は図１に示すように結束バンド部１３とバンド連結固定部１５とを備えている。結束バンド部１３は、図１、図２（ａ）に示すように、ゴム、プラスチック材等からなる可撓性の主バンド１７と、その一端側に、例えば、二股状（図示のＶ形状のほかにＵ形状、コ字形状、半円弧形状等を含む）に分岐して設けられた、ゴム、プラスチック材等からなる可撓性の一対の補助バンド１９、２１で構成されて全体的に可撓性を有する。そして、図１に示すように、ワイヤーハーネスを構成する電線を集束した電線束等の線材束を所定位置で、例えば、Ｔ字型に分岐して形成された分岐部２３の外周、更に詳細に説明すると、前記分岐部２３の中心から三方にＴ字型に延在する線材束２３ａ〜２３ｃのうち、中央に位置する線材束２３ｃを除き、その両側に位置する線材束２３ａ、２３ｂの外周に巻回可能になっている。
【００１７】
バンド連結固定部１５は、図１、図２（ｂ）に示すように、結束バンド部１３の主バンド１７と補助バンド１９、２１をループ状に連結固定するもので、後記するように、一端側に主バンド係止手段２５のバンド挿入係止ブロック２７が配設され、他端側に補助バンド係止手段２９の補助バンド係止部材３１が配設され、前記バンド挿入係止ブロック２７と前記補助バンド係止部材３１が可撓性アーム３３で連結されるように構成され、主にプラスチック材を成形加工することにより得られる。
【００１８】
このようなバンド連結固定部１５の構成によると、分岐部２３に線材保持具１１を装着する際、バンド連結固定部１５が分岐部２３を構成する線材束２３ａ、２３ｂの外周面に沿って容易に折れ曲がって隙間なく密着するので、分岐部２３を結束バンド部１３とバンド連結固定部１５間に確実に挟着することができる。また、主バンド係止手段２５のバンド挿入係止ブロック２７の主バンド１７引出し側のスペースが補助バンド係止部材３１で邪魔されず広くなるので、結束バンド部１３の主バンド１７の自由端側をバンド挿入係止ブロック２７から容易、且つ、円滑に引張り出すことができ、線材保持具１１の装着の作業性が向上するほか、線材束２３ａ、２３ｂを締め付け易くなり、分岐部２３の結束の信頼性が向上するので好ましい。
【００１９】
本発明の線材保持具１１は、更に、結束バンド部１３の主バンド１７とバンド連結固定部１５を係止する主バンド係止手段２５と、結束バンド部１３の補助バンド１９、２１とバンド連結固定部１５を係止する補助バンド係止手段２９を備えている。
【００２０】
主バンド係止手段２５は、図１に示すように、結束バンド部１３の主バンド１７の自由端側に設けられた係止部３５と、バンド連結固定部１５の一端側に配設されたバンド挿入係止ブロック２７とを有する。係止部３５は主バンド１７の自由端側の外面に長手方向に沿って連続的に設けられる。この係止部３５は多数の連続する係止凹部（係止溝部）、係止凸部、又は、細長い貫通穴（窓）等で構成される。
【００２１】
バンド挿入係止ブロック２７は、図示のものは矩形状筒体で形成され、該筒体の挿入穴に一側から前記主バンド１７の自由端側が挿入され、該ブロック２７の反対側から引張り出せるようになっている。なお、該ブロック２７は、図示省略するが、例えば、ブロック本体の一方面に主バンド１７を挿入案内するコ字状で開口縁をバンド外れ防止のために少し内側に折り曲げた案内溝を設けて形成され、その案内溝に主バンド１７の自由端側が挿入されて該ブロック２７の反対側から引張り出せるようにしたもの等でもよい。また、バンド挿入係止ブロック２７の主バンド引出し側の側壁には、先端内側に突出する爪（図示せず）を有し、先端側が内側（主バンド１７側）に付勢される弾性係止片からなる係止体３７が設けられ、前記主バンド１７の自由端側が挿入されたとき、その係止体３７の爪が主バンド１７の係止部３５に係合し、主バンド１７の戻り方向の移動が拘束されるようになっている。
【００２２】
補助バンド係止手段２９は、図１に示すように、結束バンド部１３の前記二股状に分岐して設けられた各補助バンド１９、２１の相互に離隔する先端側に設けられた係止穴３９、３９と、バンド連結固定部１５の他端側に配設された板状体からなる補助バンド係止部材３１の前記係止穴３９、３９に対応する部位に設けられ、前記係止穴３９、３９に挿入係止される係止凸部４１、４１とを組み合わせて構成される。
【００２３】
係止穴３９、３９は、図２（ａ）に示すように、大円形穴部３９ａと小円形穴部３９ｂを連通させた略だるま形状をしており、小円形穴部３９ｂが補助バンド１９、２１の先端を向くように配置されている。また、係止凸部４１、４１は円形ピン４１ａとその頭部に突設された円形鍔４１ｂとからなり、円形ピン４１ａの外径が前記係止穴３９、３９の小円形穴部３９ｂの内径よりも若干小さく、また、円形鍔４１ｂの外径が前記係止穴３９、３９の大円形穴部３９ａの内径よりも若干小さいが小円形穴部３９ｂの内径よりも大きくなるように形成されている。
【００２４】
このような補助バンド係止手段２９で結束バンド部１３の補助バンド１９、２１とバンド連結固定部１５を係止する場合には、結束バンド部１３の補助バンド１９、２１に設けられた係止穴３９、３９の大円形穴部３９ａを、バンド連結固定部１５に配設された補助バンド係止部材３１に設けられた係止凸部４１、４１の真上に配置し、補助バンド１９、２１を補助バンド係止部材３１の上に押し付けるようにして、係止穴３９、３９の大円形穴部３９ａに係止凸部４１、４１を挿入した後、補助バンド１９、２１を引いて係止穴３９、３９の小円形穴部３９ｂに係止凸部４１、４１の円形ピン４１ａを食い込ませて係止する。そうすると、円形ピン４１ａが小円形穴部３９ｂと円形鍔４１ｂで横方向及び縦方向の移動が拘束されて抜け止めロックされる。係止凸部４１、４１を係止穴３９、３９から脱着する場合には、係止凸部４１、４１の円形ピン４１ａを係止穴３９、３９の大円形穴部３９ａの方に移動させて円形ピン４１ａのロックを外し、係止凸部４１、４１を係止穴３９、３９から抜き出す。
【００２５】
なお、図示の補助バンド係止手段２９は、結束バンド部１３の各補助バンド１９、２１の先端側に係止穴３９、３９が設けられ、バンド連結固定部１５の補助バンド係止部材３１に係止凸部４１、４１が設けられているが、反対に、結束バンド部１３の各補助バンド１９、２１の先端側に係止凸部４１、４１が設けられ、バンド連結固定部１５の補助バンド係止部材３１に係止穴３９、３９が設けられていてもよい。このような構成のものでも同じ機能が得られる。
【００２６】
前記構成の補助バンド係止手段２９によると、線材保持具１１を前記分岐部２３に装着する場合、主バンド係止手段２５のバンド連結固定部１５側のバンド挿入係止ブロック２７に結束バンド部１３の主バンド１７の自由端側を所定量挿入して仮係止する作業を装着作業前に予め行っておき、装着作業時には、線材保持具１１の結束バンド部１３とバンド連結固定部１５間の所定位置に結束すべき分岐部を位置決め配置した後、単に結束バンド部１３の補助バンド１９、２１を分岐部２３を構成する線材束２３ａ、２３ｂの外周に沿って折り曲げてバンド連結固定部１５に、いずれか一方の係止穴３９、３９に他方の係止凸部４１、４１を挿入係止することにより、結束バンド部１３とバンド連結固定部１５間に分岐部２３を挟着することが可能になる。従って、分岐部２３に線材保持具１１を簡単に装着することができ、線材保持具１１の装着作業性がより向上し、装着作業の自動化を図れるので好ましい。
【００２７】
次に、上記実施形態の線材保持具１１（図１、２参照）を分岐部２３に装着して分岐部を結束し、所望の形状に保持する方法を図３〜５により説明する。結束の対象となる分岐部２３は、前記したように、ワイヤーハーネスを構成する電線束等の線材束を所定位置で、例えば、Ｔ字型に分岐し、その中心から三方に線材束２３ａ〜２３ｃがＴ字型に延在するように形成されるものである。線材保持具１１は、予め主バンド係止手段２５のバンド挿入係止ブロック２７に結束バンド部１３の主バンド１７の自由端側を分岐部２３の外径サイズに応じて所定量挿入して仮係止されている。
【００２８】
先ず、図３に示すように、線材保持具１１の結束バンド部１３の主バンド１７と補助バンド１９、２１を同じ平面上に広げて開き、主バンド１７と補助バンド１９、２１の連結点、即ち、主バンド１７の一端側に補助バンド１９、２１が二股状に分岐して設けられる分岐点とＴ字型の分岐部２３の中心がほぼ合致するように、また、分岐部２３の中央に位置する線材束２３ｃが補助バンド１９、２１間の三角状スペース上に来るように、更に、分岐部２３の両側に位置する線材束２３ａ、２３ｂが主バンド１７の長手方向軸線に直交するようにして、結束バンド部１３の上に分岐部２３を位置決め配置する。
【００２９】
次に、図４に示すように、結束バンド部１３の補助バンド１９、２１を矢印Ｂ方向（図４で反時計方向）に回動すると共に、バンド連結固定部１５の可撓性アーム３３を矢印Ｃ方向（図４の時計方向）に回動して、分岐部２３の線材束２３ａ、２３ｂの各外周に結束バンド部１３及びバンド連結固定部１５を巻回し、補助バンド係止手段２９により、その係止穴３９、３９に係止凸部４１、４１を挿入係止して、これら線材束２３ａ、２３ｂを結束バンド部１３とバンド連結固定部１５間に挟着する。この際、分岐部２３の中央に位置する線材束２３ｃも補助バンド１９、２１間に挟着する。その後、主バンド係止手段２５により、結束バンド部１３の主バンド１７の自由端側をバンド挿入係止ブロック２７から矢印Ｄ方向に引張り出して線材束２３ａ、２３ｂを締め付ける。このようにして、図５に示すように、線材保持具１１を分岐部２３に装着して分岐部２３を結束し所定形状に保持する。
【００３０】
前記構成の線材保持具１１によると、その結束バンド部１３とバンド連結固定部１５間の所定位置に位置決め配置された分岐部２３を結束バンド部１３とバンド連結固定部１５間に挟着し、バンド連結固定部１５側のバンド挿入係止ブロック２７に挿入された結束バンド部１３の主バンド１７の自由端側をバンド挿入係止ブロック２７から引張り出すことにより締め付けるので、分岐部２３を複数箇所で同時に、且つ、均等な締付力で十分に締め付けることが可能になる。これにより、分岐部２３が形状崩れを起こしたり、長手方向へ位置ずれを起こしたりすることがなくなり、分岐部２３を正しい位置に保持して固定することが出来る。
【００３１】
また、分岐部２３を構成する線材束２３ａ、２３ｂの外径サイズが異なってもサイズ変更に十分対応することが可能なので、汎用性に優れ、各外径サイズ毎に適応した線材保持具１１を予め数多く製作しておく必要がなくなり、コストを低減することができる。更に、数ある線材保持具１１の中から適応する線材保持具１１を選択して装着する必要もなくなるので、分岐部２３に対する装着作業の工数を低減することもできる。
【００３２】
なお、前記実施形態の説明においては、Ｔ字型の分岐部２３に線材保持具１１を装着して分岐部２３を所定の形状を保持するように結束する場合について説明したが、分岐部２３の形状はＴ字型のものだけに限定されない。そのほかに、Ｙ字型のものとか、直線状の線材束を所定位置で斜め方向に分岐した略Ｙ字型のものとか、分岐部２３の中央に位置する線材束２３ｃに相当する線材束が２以上に分岐されているもの等にも適用可能である。
【００３３】
また、前記補助バンド係止手段２９は係止穴３９、３９とこれに挿入係止される係止凸部４１、４１とを組み合わせて構成されるものだけに限定されない。そのほかに、図示省略するが、例えば、主バンド係止手段２５に相当するような構成のものとしてもよい。この場合、例えば、補助バンド１９、２１の自由端側に係止部３５に相当するものが設けられ、バンド連結固定部１５の他端側に、直に、又は、補助バンド係止部材３１を介して、自由端側から挿入された補助バンド１９、２１の戻り方向の移動を拘束するバンド挿入係止ブロック２７に相当するものが離隔して配設される。さらに、分岐部２３を結束した状態の線材保持具１１を車体、電気機器等のパネル、壁等の支持部材に取り付けるために、先端が矢尻状に突出する形状等を有するクリップを、主バンド係止手段２５におけるバンド挿入係止ブロック２７の外側壁に取り付けるようにしてもよい。このようにすると、分岐部２３のほぼ中心部を支持部材に固定することが可能になり、分岐部２３の取り付け精度を向上することができるので好ましい。
【００３４】
【発明の効果】
以上述べたように、本発明の請求項１に記載された線材保持具によると、線材保持具の結束バンド部とバンド連結固定部間の所定位置に位置決め配置された分岐部を結束バンド部とバンド連結固定部間に挟着し、バンド連結固定部側のバンド挿入係止ブロックに挿入された結束バンド部の主バンドの自由端側をバンド挿入係止ブロックから引張り出すことにより締め付けるので、分岐部を複数箇所で同時に、且つ、均等な締付力で十分に締め付けることが可能になる。これにより、分岐部が形状崩れを起こしたり、長手方向へ位置ずれを起こしたりすることがなくなり、分岐部を正しい位置に保持して固定することが出来る。
【００３５】
本発明の請求項２に記載された線材保持具によると、線材保持具を前記分岐部に装着する場合、主バンド係止手段のバンド連結固定部側のバンド挿入係止ブロックに結束バンド部の主バンドの自由端側を所定量挿入して仮係止する作業を装着作業前に予め行っておき、装着作業時には、線材保持具の結束バンド部とバンド連結固定部間の所定位置に結束すべき分岐部を位置決め配置した後、単に結束バンド部の補助バンドを分岐部を構成する線材束の外周に沿って折り曲げてバンド連結固定部に、いずれか一方の係止穴に他方の係止凸部を挿入係止することにより、結束バンド部とバンド連結固定部間に分岐部を挟着することが可能になる。従って、分岐部に線材保持具を簡単に装着することができ、線材保持具の装着作業性がより向上し、装着作業の自動化を図れるので好ましい。
【００３６】
本発明の請求項３に記載された線材保持具によると、分岐部に線材保持具を装着する際、バンド連結固定部が分岐部を構成する線材束の外周面に沿って容易に折れ曲がって隙間なく密着するので、分岐部を結束バンド部とバンド連結固定部間に確実に挟着することができる。また、主バンド係止手段のバンド挿入係止ブロックの主バンド引出し側のスペースが補助バンド係止部材で邪魔されず広くなるので、結束バンド部の主バンドの自由端側をバンド挿入係止ブロックから容易、且つ、円滑に引張り出すことができ、線材保持具の装着の作業性が向上するほか、線材束を締め付け易くなり、分岐部の結束の信頼性が向上するので好ましい。
