図5に記載の例では、本体部ガイド4は、ベース3に対して位置調整可能である。より具体的には、本体部ガイド4は、ベース3に対して第2方向DR2に平行な方向に位置調整可能なようにベース3に取り付けられている。
図2に記載の例では、本体部ガイド4は、取付部46と、ルーフ部43とを有する。本体部ガイド4は、第1ウイング部44および/または第2ウイング部45を有していてもよい。
図3に記載の例では、ストッパ面430は、第1方向DR1に沿う方向に見て、略逆V字形状を有する。より具体的には、ストッパ面430は、頂部433と、頂部433から第4方向DR4に向かうにつれてベース3に近づく第1傾斜面431と、頂部433から第4方向DR4と反対方向に向かうにつれてベース3に近づく第2傾斜面432とを含む。ストッパ面430が略逆V字形状を有する場合、第4方向DR4に平行な方向における防護管9の位置ずれが防止または抑制される。
図3に記載の例では、本体部ガイド4は、ストッパ面430よりも第3方向DR3側に配置される防護管誘導面440を有する。防護管誘導面440は、第3方向DR3に向かうにつれて防護管9が通る軌道から離れる方向に傾斜する傾斜面であることが好ましい。当該傾斜面は、平面によって構成されていてもよいし、曲面によって構成されていてもよい。
図5に記載の例では、本体部ガイド4は、ストッパ面430よりも第1方向DR1側に配置される防護管取出面450を有する。防護管取出面450は、第1方向DR1に向かうにつれて防護管9が通る軌道から離れる方向に傾斜する傾斜面であることが好ましい。当該傾斜面は、平面によって構成されていてもよいし、曲面によって構成されていてもよい。
図6乃至図13を参照して、第2の実施形態における防護管取付器1Bについて説明する。図6は、第2の実施形態における防護管取付器1Bを斜め前方側から見たときの概略斜視図である。図7は、第2の実施形態における防護管取付器1Bを斜め後方側から見たときの概略斜視図である。図8および図9は、第2の実施形態における防護管取付器1Bを模式的に示す概略正面図である。図10は、第2の実施形態における防護管取付器1Bを模式的に示す概略側面図である。図11は、第2の実施形態における防護管取付器1Bを模式的に示す概略平面図である。図12は、第2の実施形態における防護管取付器1Bを模式的に示す概略側面図である。図13は、第2の実施形態における防護管取付器1Bを模式的に示す概略底面図である。
図7に記載の例(防護管取付器1Bを斜め後方側から見た例)では、ジッパーガイド2は、第1ジッパーガイド2Aを含む。また、第1ジッパーガイド2Aは、第1ガイドローラ21aおよび第2ガイドローラ21bを含む。第1ガイドローラ21aは、ジッパー部92が第1方向DR1に移動するとき、ジッパー部92の第1リブ92aを、第2リブ92bに向けて押圧する。他方、第2ガイドローラ21bは、ジッパー部92が第1方向DR1に移動するとき、ジッパー部92の第2リブ92bを、第1リブ92aに向けて押圧する。こうして、ジッパー部92が第1ガイドローラ21aと第2ガイドローラ21bとの間を通過することにより、ジッパー部92の状態が非結合状態から結合状態に切り替えられる。なお、第1ガイドローラ21aは、第1リブ92aに当接する第1リブガイド20aとして機能し、第2ガイドローラ21bは、第2リブ92bに当接する第2リブガイド20bとして機能する。
図7に記載の例では、ベース3は、ブロック(より具体的には、扁平形状を有するブロック)によって構成されている。ベース3は、1つの部品によって構成されていてもよいし、複数の部品のアセンブリによって構成されていてもよい。図7に記載の例では、ベース3の一側部に、第1ガイド4Aが取り付けられ、ベース3の他側部に、第2ガイド4Bが取り付けられている。また、ベース3の上面には、ジッパーガイド2が配置されている。図7に記載の例では、ベース3は、平面視略矩形形状を有するが、ベース3の形状は、平面視略矩形形状に限定されない。
図8に記載の例では、防護管取付器1Bは、ユーザが把持可能なハンドル62を備える。ハンドル62は、例えば、ベース3に取り付けられる。図8に記載の例では、ハンドル62は、ベース3の下面から下方に向かって突出するように配置されている。この場合、防護管9を、防護管取付器1Bに対して第1方向DR1に相対移動させる際に、ハンドル62が邪魔になることがない。
図6に記載の例では、第1ガイド4Aは、第1取付部46Aと、第1ルーフ部43Aとを有する。第1ガイド4Aは、第1ウイング部44Aおよび/または第2ウイング部45Aを有していてもよい。
第2ガイド4Bの構成は、第1ガイド4Aの構成と同様である。よって、上述の「(第1ガイド4A)」の説明において以下の読み替えを行うことにより、上述の「(第1ガイド4A)」の説明を「(第2ガイド4B)」の説明に代替する。より具体的には、上述の「(第1ガイド4A)」の説明において、「図6」、「図7」、「図8」、「第1ガイド4A」、「第1取付部46A」、「第1ルーフ部43A」、「第1ウイング部44A」、「第2ウイング部45A」、「第1長孔4h-1」、「第1位置決め部41A」、「第2位置決め部42A」、「第1固定部材51A」、「第1操作つまみ511A」、「第1位置P1」、「第2位置P2」、「第1係合凹部」、「第2係合凹部」、「第1ガイドローラ21a」、「第2ガイドローラ21b」、「第1ジッパーガイド2A」、「端部43e-1」、「第1開口部OP-1」、「第1ストッパ面430A」、「第1頂部433A」、「第1傾斜面431A」、「第2傾斜面432A」、「第1の防護管誘導面440A」、「第1の防護管取出面450A」を、それぞれ、「図7」、「図6」、「図9」、「第2ガイド4B」、「第2取付部46B」、「第2ルーフ部43B」、「第3ウイング部44B」、「第4ウイング部45B」、「第2長孔4h-2」、「第3位置決め部41B」、「第4位置決め部42B」、「第2固定部材51B」、「第2操作つまみ511B」、「第3位置P3」、「第4位置P4」、「第3係合凹部」、「第4係合凹部」、「第3ガイドローラ21c」、「第4ガイドローラ21d」、「第2ジッパーガイド2B」、「端部43e-2」、「第2開口部OP-2」、「第2ストッパ面430B」、「第2頂部433B」、「第3傾斜面431B」、「第4傾斜面432B」、「第2の防護管誘導面440B」、「第2の防護管取出面450B」に読み替えることにより、「(第2ガイド4B)」の説明とする。
図13に記載の例では、防護管取付器1Bは、電線を把持可能な電線把持具に連結される可撓性部材63(例えば、ワイヤ、ロープ、ケーブル、紐等の線状材、あるいは、ベルト等の帯状材)を保持する第1保持部65を備える。この場合、電線把持具および可撓性部材63によって、防護管取付器1Bの第1方向DR1への移動が制限される。よって、防護管取付器1Bの第1方向DR1への移動が防止された状態で、防護管9を防護管取付器1Bに対して第1方向DR1に相対移動させることができる。こうして、防護管9を防護管取付器1Bに対して第1方向DR1に相対移動させることにより、ジッパー部92の状態を非結合状態から結合状態に切り替える作業をより容易に実施することができる。なお、第1保持部65の構成は、第1の実施形態における防護管取付器1Aにおいて採用されてもよい。
図14を参照して、第3の実施形態における防護管取付装置100について説明する。図14は、第3の実施形態における防護管取付装置100を模式的に示す概略斜視図である。
続いて、図1乃至図18を参照して、実施形態における防護管取付方法について説明する。図15乃至図17は、防護管取付方法の一工程(より具体的には、移動工程)を実行中の様子を模式的に示す概略側面図である。図18は、実施形態における防護管取付方法の一例を示すフローチャートである。
