Description

[Technical field]

[0001] This invention relates to a mooring hook that can be easily removed by one person when a ship removes the mooring hook from an oyster raft. [Background technology]

[0002] Ships are sometimes moored to oyster rafts. Oyster rafts are rafts for oyster farming, made of bamboo or other rods arranged in a lattice and tied together with wire. In addition, styrofoam is used as a buoyant body to float in the sea, and concrete blocks connected to the raft with wire are sunk to the seabed to prevent it from drifting away. Figures 1 and 2 show how a ship is moored to a raft. Figures 3 to 6 are diagrams of conventional mooring hooks. When a ship is moored to an oyster raft, a rope is used to secure the ship and the oyster raft, and a mooring hook (Figure 6) is connected to the end of the rope on the oyster raft side to hook it to the oyster raft's holding bar F, and the mooring hook (Figure 6) is composed of a ring D for connecting the rope and a bent part for hooking it to the holding bar F. When a ship moored to oyster raft G (Figures 1 and 2) leaves oyster raft G, as shown in Figures 3, 4, and 5, the mooring hook rope A must be loosened (Figure 3), then pulled tightly (Figure 4), and twisted (Figure 5) on board the ship in order to remove the bent part of the mooring hook H from the holding bar F, as shown in Figures 3, 4, and 5, until the bent part of the mooring hook that is hooked onto the holding bar F can be removed from the holding bar F.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 4-254282 Summary of the Invention [Problem to be solved by the invention]

[0004] When leaving oyster raft G, in order to remove mooring hook H, it is necessary to remove the bent part of mooring hook H, which is connected to the end of mooring hook rope A, from holding bar F. This is an uncertain action that relies on chance, and it is difficult for one person to change the direction of mooring hook H when the tide is fast, the waves are big, the wind is strong, or visibility is difficult at night, so in many cases, assistance from one or more people on the boat is required, such as descending to oyster raft G from the boat and directly removing mooring hook H by hand. [Means for solving the problem]

[0005] The present invention, which is intended to solve the above problems, is a mooring hook characterized in that a release rope attachment portion is provided at the bent tip portion of the hook portion. Effect of the Invention

[0006] The mooring hook I (Fig. 7) of the present invention has a release rope C attached to the release rope fixing ring B, so that the mooring hook can be easily removed from the holding bar F by simply pulling the release rope C. It can also be easily removed even when there is a crosswind, when the waves are large, or when visibility is poor at night. In addition, by passing the release rope C through the rope connection ring D of the mooring hook, the operation becomes more rational and stable, and it can be removed reliably even by one person.

[0008] Fig. 7 is a diagram of the mooring hook I of the present invention, with a release rope fixing ring B attached to the tip of the curved part of the hook as a release rope attachment part. It is composed of a rope connection ring D for connecting the rope and a release rope fixing ring B having a curved part for hooking onto a holding bar F and for attaching the release rope.

[0009] FIG. 8 is a diagram showing the mooring hook I of the present invention in use, with the release rope C tied to the release rope fixing ring B.

[0010] Figure 9 shows the mooring hook I of the present invention in use, with the release rope C passed through the rope connection ring D. When the release rope C is pulled, a space is created between the holding bar F and the mooring hook I of the present invention along the direction parallel to the mooring hook rope A, as shown in Figure 11, and the bent portion comes out of the holding bar F, resulting in a more stable operation of the release rope C than in the state shown in Figure 8.

[0011] Figure 10 is a diagram of the mooring hook I of the present invention moored to an oyster raft G, with the bent part of the mooring hook hooked on the holding bar F and the release rope C also running along the holding bar F.

[0012] Figure 11 shows that when leaving oyster raft G, the mooring hook rope A is loosened on board the ship and the release rope C is pulled, causing the bent part of the mooring hook to almost come off the retaining bar F.

[0013] FIG. 12 shows the release rope C being pulled further and the bent portion of the mooring hook coming off the retaining bar F.

[0014] FIG. 13 shows the mooring hook I of the present invention released from the holding bar F by further pulling the release rope C.

[0015] In the states of Figures 11 and 12, even if the mooring hook I falls to the left or right in the direction in which the release rope C is pulled due to balance when the release rope C is pulled, it can be removed from the holding bar F by following the movement of the release rope C. Furthermore, by attaching a rope stopper to the rope connection ring D position in order to fix the release rope C in a pulled state, removal of the mooring hook I becomes even easier, and it can be removed reliably even by one person.
