To provide a hook engagement device in which a mechanism for attaching and detaching a double hook and a pair of turning arms is realized with a simple configuration.SOLUTION: A hook engagement device (10) includes: a support shaft (11); a pair of turning arms (12, 13) extending obliquely upward so as to form a first angle in a natural state; link portions (16, 17) that are pressed by a double hook (8) inserted between the pair of turning arms (12, 13) and narrow an angle formed by the pair of turning arms (12, 13) to a second angle, smaller than the first angle, from the first angle; lock mechanisms (30, 23c) that lock the pair of turning arms (12, 13) to the second angle; a pair of engaging portions (14, 15) with which two hooks (8a, 8b), composing the double hook (8), engage while the pair of turning arms (12, 13) are kept locked at the second angle; and releasing portions (14, 15) that are pressed by the double hook (8) to release the lock caused by the locking mechanisms (30, 23c).SELECTED DRAWING: Figure 5

    【課題】ダブルフックと一対の回動アームとの着脱機構をシンプルな構成で実現したフック係合装置を提供する。【解決手段】フック係合装置(10)は、支軸(11)と、自然状態で第1角度をなすように斜め上方に延びる一対の回動アーム(12、13)と、一対の回動アーム(12、13)の間に進入したダブルフック(8)に押圧されて、一対の回動アーム(12、13)のなす角を、第1角度から第1角度より小さい第2角度に狭めるリンク部(16、17)と、一対の回動アーム(12、13)を第2角度にロックするロック機構(30、23c)と、一対の回動アーム(12、13)が第2角度にロックされた状態で、ダブルフック(8)を構成する2つのフック(8a、8b)が係合する一対の係合部(14、15)と、ダブルフック(8)に押圧されてロック機構(30、23c)によるロックを解除する解除部(14、15)とを備える。【選択図】図5
