Claims

[Scope of utility model registration request]

A vertically elongated hole in the vertical direction is provided in the frame suspended from the hoisting wire, and a rotating shaft to which a rotating hook is connected is installed in the vertically movable vertical hole, and the rotating shaft is placed between the rotating shaft and the frame. Attach an elastic body that biases upward, and the above rotating hook,
The frame is formed by alternately arranging a pair of hook pieces and a pair of engagement arms that are symmetrical with respect to the rotation axis, and when one of the hook pieces is held upward in the frame, the rotation axis is aligned with the rotation axis. At the upper limit position, the tip of the engagement arm located above comes into contact with the first stopper to stop the forward rotational movement of the rotary hook when a load is applied to the hook piece, and at the lower limit position of the rotary shaft, the engagement arm contacts the first stopper. A second stopper is provided with which the tip of the engaging arm comes into contact to stop the rotational movement of the rotating hook in the forward rotational direction, and when the rotating shaft moves from the lower limit position to the upper limit position, the engaging arm stops moving. A locking portion is provided whose tip abuts to stop the rotating hook from moving in the reverse rotation direction, and the engaging arm is further provided with a groove through which the second stopper can pass when the rotating hook is rotated at the upper limit position of the rotating shaft. A hanging device made of
