従来、工事現場やイベント会場等にコーンを設置し、コーンの先端の間に横架して周囲の通行を遮断するバー本体を有するコーンバーが利用されている。しかしながら、コーンバーの長さは一般的に１ｍ〜３ｍ程度であるため輸送・保管等のスペースが必要とされるため不便であり、大規模な工事現場やイベント会場に大量のコーンバーを輸送する際に大型の荷台を有するトラック等を必要とし、輸送費が増大する欠点があった。   BACKGROUND ART Conventionally, a cone bar having a bar main body that installs a cone at a construction site or an event site and horizontally extends between the ends of the cone to block the surrounding traffic has been used. However, the length of the cone bar is generally about 1 m to 3 m, which is inconvenient because space for transportation and storage is required, and when transporting a large number of cone bars to a large-scale construction site or event site. There is a drawback that a transportation cost increases because a truck or the like having a large cargo bed is required.

そこで、上記欠点を解決するため、従来のバー本体部を分解した状態で輸送・保管し、輸送した後の工事現場等において分解されたバー本体に連結部を介して連結固定してなるコーンバーが提案されている。例えば、特許文献１記載の発明において、連絡パイプ２にコーンバーを差し込んでなるコーンバーが記載されている。また、特許文献２記載の発明において、バー本体２の両端部に、継手１６を介してバーエンド部分３、４を接続してなるソーラーコーンバー１が記載されている。   Therefore, in order to solve the above drawbacks, there is a cone bar that is transported and stored in a state where the conventional bar main body is disassembled, and is connected and fixed to the disassembled bar main body at a construction site after transportation through a connecting portion. Proposed. For example, in the invention described in Patent Document 1, a cone bar in which a cone bar is inserted in the connecting pipe 2 is described. Further, in the invention described in Patent Document 2, a solar cone bar 1 in which the bar end portions 3 and 4 are connected to both ends of the bar main body 2 via joints 16 is described.
