To provide a hook of a novel structure which can safely perform a detaching work of the hook from the block installed on a water surface by remote operation.SOLUTION: A hook 10 has a main body 11 with a hanging ring 14 on its upper portion, a rotating body 16 connected rotatably to the lower end portion of the main body and a lock arm 17 connected rotatably to the intermediate portion of the main body. The rotating body is locked in the closed state against the main body at the lock position (the virtual line in Fig. 1) when the lock arm is rotated downward by its own weight. By pulling up the operation wire 22 connected to the lock arm tip by the remote operation and rotating upwardly the lock arm at the lock position, the rotating body is automatically unlocked by its own weight (the solid line in Fig. 1) and the slinging work wire attached to the rotating body can be removed safely.SELECTED DRAWING: Figure 1

    【課題】水面上に設置したブロックからフックを取り外す作業を遠隔操作により安全に行うことができる新規構造のフックを提供する。【解決手段】上端部に吊環14を有する本体11と、本体の下端部に回動自在に連結された回転体16と、本体の中間部に回動自在に連結されたロックアーム17とを有してなるフック10。ロックアームが自重で下方に回転したロック位置において、回転体は本体に対して閉止状態にロックされる(図1仮想線)。ロックアーム先端に連結した操作ワイヤー22を遠隔操作により引き上げて、ロック位置にあるロックアームを上方に回転させることにより、回転体が自重により自動的にロック解除され(図1実線)、回転体に取り付けた玉掛けワイヤーを安全に取り外すことができる。【選択図】図1
