[0013] An embodiment of the outfitted mooring hook of the present invention will be described below with reference to the drawings. The outfitted mooring hook of the present invention is outfitted on the deck of a vessel (e.g., a soil carrier or other vessel) and is used to moor the vessel to its host vessel. The outfitted mooring hook of the present invention is also used to moor a vessel to a quay or pier in a port. In these mooring operations, the outfitted mooring hook reduces the manual workload and prevents workers from getting their fingers caught or falling into the sea. The outfitted mooring hook also releases the mooring line without manual labor when leaving the ship's side or leaving shore, ensuring the safety of workers and reducing their workload. Furthermore, the outfitted mooring hook can release the mooring line without manual labor when the vessel is evacuated in the event of a tsunami or fire, allowing the vessel to be evacuated. [First embodiment]

[0014] As shown in Figs. 1 and 2, the outfitted mooring hook 11 is detachably attached to a cylindrical bollard 13 provided so as to protrude upward on a deck 12 of a ship or the like.

[0015] 1 to 4, the outfitted mooring hook 11 comprises a main body 16 that is attached directly to a bollard 13 and has a receiving portion 15 that receives a mooring line 14, a claw member 17 that is rotatable relative to the main body 16 between a lock position P1 and a release position P2, an actuator 18 that rotates the claw member 17 as described above, and a controller 21 that operates the actuator 18. A release hook manufactured by Sugita Sangyo Co., Ltd. can be used as part of the outfitted mooring hook 11.

[0016] The main body 16 comprises a hook member 22 that defines the receiving portion 15 on its inner surface (upper surface), a pair of auxiliary claws 23 that protrude above the receiving portion 15, a cylindrical ring member 24 that is fastened to the outer surface of the bollard 13, and a connecting portion 25 that is provided between the hook member 22 and the ring member 24 and connects them.

[0017] The hook member 22 is formed by joining two cast steel components with bolts, nuts, etc., to have a hollow portion 26 therein. The hook member 22 can accommodate a portion of the claw member 17 and the actuator 18 in the hollow portion 26. The hook member 22 is crescent-shaped when viewed from the side. The hook member 22 has a receiving portion 15 on its inner circumferential surface (upper surface) for hooking and holding the mooring line 14. In other words, the hook member 22 defines the receiving portion 15 on its inner circumferential surface (upper surface). The hook member 22 has a through hole 28 for passing the first shaft portion 27 of the claw member 17 therethrough, a fixing hole 31 for attaching to the connecting portion 25, and a second through hole 32 located between the through hole 28 and the fixing hole 31 and for passing the second shaft portion 45 of the link member 42A therethrough.

[0018] Each of the pair of auxiliary claws 23 protrudes upward from the top surface of the hook member 22. The auxiliary claws 23 protrude upward from positions near the fixing holes 31 at both ends of the hook member 22 in the thickness direction. The auxiliary claws 23 are made of cast steel and formed into an inverted "L" shape. That is, the auxiliary claws 23 first protrude upward from the hook member 22 and then protrude away from the connecting portion 25. This allows the auxiliary claws 23 to form a bag-like shape around the receiving portion 15, and the mooring line 14 can be held inside the auxiliary claws 23 on the receiving portion 15. The auxiliary claws 23 have a shaft 23A at their base. When a force is applied from above, the tip side can rotate downward around the shaft 23A, and when the force from above is released, the tip side can return to its original position (the horizontal position shown in FIG. 1 ).

[0019] The ring member 24 is made of cast steel and is formed into a substantially cylindrical shape. The ring member 24 has a first portion 24A that is semicircular when viewed from above and connected to the connecting portion 25, a second portion 24B that is also semicircular when viewed from above, and a third portion 24C that sandwiches the flange portion 13A of the bollard 13 between the second portion 24B and the first portion 24A. The first portion 24A and the second portion 24B are integrated into a cylindrical shape by fastening multiple bolts and nuts 33, and are firmly fixed to the outer peripheral surface 13B of the bollard 13. The first portion 24A and the second portion 24B are detachably fixed to the outer peripheral surface 13B of the bollard 13.

[0020] The third portion 24C is formed in a crescent shape when viewed from above. The third portion 24C is attached to the upper portion of the second portion 24B, and by sandwiching a part of the flange portion 13A of the bollard 13 between the third portion 24C and the upper portion of the second portion 24B, the ring member 24 can be firmly fixed to the bollard 13.

[0021] Each part of the connecting portion 25 is made of cast steel. The connecting portion 25 has a first joint portion 34, which is provided at a position directly connected to the first portion 24A of the ring member 24 and supports the hook member 22 so that it can swing left and right, and a second joint portion 35, which is provided further distal (toward the hook member 22) than the first joint portion 34 and supports the hook member 22 so that it can swing up and down. The first joint portion 34 has a first pin 34A and can support the hook member 22 so that it can swing left and right in a range of, for example, 140 to 180 degrees around the first pin 34A in a horizontal plane. The second joint portion 35 has a second pin 35A that is passed through the fixing hole 31 of the hook member 22 and can support the hook member 22 so that it can swing up and down in a range of, for example, 10 to 30 degrees around the second pin 35A.

[0022] As shown in FIGS. 1 and 3, the claw member 17 is integrally formed from cast steel so as to have an overall "J" shape when viewed from the side. The claw member 17 has a hook-shaped claw body 36 that forms a barb, a first shaft portion 27 that is provided at the base of the claw body 36 and protrudes cylindrically outward in the thickness direction of the hook member 22, and a holding portion 37 that extends rod-like from the base of the claw body 36 toward the connecting portion 25 (fixing hole 31). The first shaft portion 27 is inserted into a through-hole 28. The claw member 17 can rotate about the first shaft portion 27 between a locked position P1 shown in FIGS. 1 and 3 and a released position P2 shown in FIG. 4.

[0023] When the claw body 36 is in the lock position P1, it can block the outlet of the receiving portion 15 and hold the mooring line 14 in the receiving portion 15. When the claw body 36 is in the release position P2, it can open the outlet of the receiving portion 15 and release the mooring line 14 to the outside from the receiving portion 15.

[0024] As shown in FIG. 3 , the actuator 18 includes an actuator body 41, which may be a fluid cylinder, for example, and a power transmission mechanism 42 that transmits power from the actuator body 41 to the pawl member 17. The actuator body 41 is housed inside the hollow portion 26 of the hook member 22. The actuator body 41 may be a pneumatic cylinder, for example, and has a retractable cylinder portion 41A. The actuator body 41 can extend or retract the cylinder portion 41A by introducing compressed air from a compressor (not shown) under switching control of the controller 21. The actuator body 41 is not limited to a pneumatic cylinder. The actuator body 41 may be a hydraulic cylinder, a solenoid, or another actuator, for example.

[0025] The power transmission mechanism 42 is formed, for example, by a link member 42A. The link member 42A has a pouch portion 43 provided at one end thereof so as to have a pouch-shaped cross section capable of holding the tip of the holding portion 37 of the hook body 36, a lever portion 44 provided at the other end opposite the pouch portion 43, and a second shaft portion 45 provided between the pouch portion 43 and the lever portion 44 and protruding cylindrically outward in the thickness direction of the hook member 22. The second shaft portion 45 is passed through the second through-hole 32. Therefore, the link member 42A is configured to be rotatable about the second shaft portion 45. The lever portion 44 includes an abutment portion 44A that abuts against the tip of the cylinder portion 41A of the actuator body 16.

[0026] In this embodiment, for example, the power transmission mechanism 42 is configured by one link member 42A, but it goes without saying that the power transmission mechanism 42 can also be configured by appropriately combining a plurality of known link members and cams.

[0027] The controller 21 is configured with a general mechanical switching valve. The controller 21 can move the cylinder part 41A forward and backward by pressing the switch 51 to appropriately switch the flow of compressed air from the compressor.

[0028] Next, the operation of the outfitted mooring hook 11 of this embodiment will be described with reference to FIGS.

[0029] As shown in Figures 1 and 2, the outfitted mooring hook 11 of this embodiment can be attached to a bollard 13 provided on a deck 12 of a ship or the like. At this time, bolts and nuts 33 are fastened to the ring member 24 to attach the first portion 24A and the second portion 24B of the ring member 24 to the outer circumferential surface of the bollard 13. A third portion 24C is attached to the second portion 24B, firmly attaching the ring member 24 to the bollard 13. A connecting portion 25 is attached to the ring member 24, and a hook member 22 is attached to the tip of the connecting portion 25. The auxiliary claw 23, claw member 17, and actuator 18 are previously attached to the hook member 22. Attaching the hook member 22 completes the installation of the outfitted mooring hook 11 of this embodiment.

[0030] When the outfitted mooring hook 11 of this embodiment attached to the bollard 13 is leaving port or leaving quay, the operator presses the switch 51 of the controller 21. This causes compressed air to be supplied from the compressor to the actuator body 16, extending the cylinder portion 41A. As a result, as shown in FIG. 3 , the abutting portion 44A of the lever portion 44 of the link member 42A is pushed in by the tip of the cylinder portion 41A, and the link member 42A of the power transmission mechanism 42 rotates about the second shaft portion 45 from a state in which the holding portion 37 is held by the bag portion 43 of the link member 42A and the claw member 17 is held at the locked position P1. As shown in FIG. 4 , at the same time that the bag portion 43 of the link member 42A is retracted, the lever portion 44 of the link member 42A pushes out the hook member 22, moving the hook member 22 from the locked position P1 to the released position P2. This allows the mooring rope 14 to be released semi-automatically without manual labor when leaving the ship's side or shore.

[0031] On the other hand, when an operator wants to hook the mooring line 14 onto the outfitted mooring hook 11 and moor a vessel or the like to a master vessel, the operator manually rotates the claw member 17 from the release position P2 shown in FIG. 4 to the lock position P1 shown in FIG. 3. This causes the holding portion 37 of the claw member 17 to be held by the pocket portion 43 of the link member 42A. The operator then hooks the mooring line 14 from above the auxiliary claw 23. The auxiliary claw 23 rotates downward about the shaft 23A located at its base position only when a force is applied from above, and returns to its original position after the force from above is released. The mooring line 14 is held in the receiving portion 15 by the claw member 17 and auxiliary claw 23 in the lock position P1 until the switch 51 is pressed again.

[0032] Also, as shown in FIG. 5, a mooring rope 14 can be wound around the outer periphery of a second bollard 19 adjacent to the bollard 13, and the mooring rope 14 can be hooked onto the equipped mooring hook 11 for mooring. When it is desired to release the mooring rope 14 again, the same procedure as above can be followed.

[0033] According to this embodiment, the following can be said: The outfitted mooring hook 11 is attached to the outer peripheral surface 13B of a cylindrical bollard 13 of a ship and comprises a main body 16 having a receiving portion 15 that receives a mooring line 14, a claw member 17 that is rotatable relative to the main body 16 between a locked position P1 in which the outlet of the receiving portion 15 is closed and a released position P2 in which the outlet of the receiving portion 15 is open, an actuator 18 that is provided on the main body 16 and that moves the claw member 17 from the locked position P1 to the released position P2, and a controller 21 that operates the actuator 18.

[0034] This configuration makes it possible to realize an outfitted mooring hook 11 that can semi-automatically release the mooring line 14 when leaving the ship's side or leaving shore. This allows the mooring line 14 to be released quickly in an emergency without imposing a burden on the worker or causing an unexpected accident.

[0035] In this case, the main body 16 includes a ring member 24 that is detachably fastened to the bollard 13 so as to surround the outer peripheral surface 13B. For example, if a hook is attached to the bollard 13 by welding, it may be difficult to restore it to its original state. With the above configuration, the outfitted mooring hook 11 can be attached to the ship's bollard 13 in a manner that allows it to be restored to its original state.

[0036] In this case, the main body 16 comprises a hook member 22 that defines the receiving portion 15, and a connecting portion 25 that is provided between the ring member 24 and the hook member 22 and connects the ring member 24 and the hook member 22 so that the hook member 22 can rotate relative to the ring member 24.

[0037] According to this configuration, even if a large force is applied to the hook member 22 from the mooring rope 14, the possibility of a malfunction such as the attachment angle of the hook member 22 being shifted can be reduced.

[0038] Next, a description will be given of different embodiments of the outfitted mooring hook 11 of this embodiment. In the following embodiments, differences from the above embodiment will be mainly described, and descriptions of parts common to the above embodiment will be omitted. [Second embodiment]

[0039] 6 and 7, a second embodiment of the outfitted mooring hook 11 will be described. The outfitted mooring hook 11 of this embodiment further has a bearing member 61 between the outer peripheral surface 13B of the bollard 13 and the ring member 24. In addition, the outfitted mooring hook 11 of this embodiment has a different shape for the third portion 24C of the ring member 24.

[0040] As shown in Figure 7, the bearing member 61 is interposed between the outer peripheral surface 13B of the bollard 13 and the inner peripheral surface of the ring member 24. The bearing member 61 may be configured as a general cylindrical ball bearing or a general cylindrical roller bearing. In the outfitted mooring hook 11 of this embodiment, the presence of the bearing member 61 allows the main body 16 (the ring member 24 and the hook member 22 fixed thereto) to rotate relative to the bollard 13. This allows the hook member 22 to rotate to any angle within a horizontal plane.

[0041] Unlike the first embodiment, the third portion 24C is formed in a disk shape. The third portion 24C is fixed to both the first portion 24A and the second portion 24B of the ring member 24 by a structure such as bolts and nuts 33. The flange portion 13A of the bollard 13 is sandwiched and held between the upper portion of the first portion 24A and the third portion 24C. Similarly, the flange portion 13A of the bollard 13 is sandwiched and held between the upper portion of the second portion 24B and the third portion 24C. The ring member 24 is detachable from the bollard 13, and has a structure that makes it easy to restore it to its original state.

[0042] The operation of the outfitted mooring hook 11 of this embodiment will now be described. In the outfitted mooring hook 11 of this embodiment, the hook member 22 can be rotated to any angle in a horizontal plane. Therefore, even if a large force is applied during mooring due to the movement or rolling of the hull, the ring member 24 fixed to the bollard 13 will not slip and the attachment angle of the ring member 24 will not be displaced. Rather, by actively rotating the ring member 24 in a horizontal plane, the ring member 24 and the hook member 22 can be rotated, thereby dissipating the large force applied to the ring member 24. The process of releasing the mooring line 14 and the process of re-mooring the mooring line 14 are the same as in the first embodiment.

[0043] According to this embodiment, the following can be said. The outfitted mooring hook 11 is provided with a bearing member 61 interposed between the outer circumferential surface 13B and the ring member 24, which allows the main body 16 to rotate around the outer circumferential surface 13B. With this configuration, by locating the bearing member 61 at the fixed portion of the ring member 24 to which force is applied by the mooring line 14, the main body 16 can rotate freely relative to the bollard 13. As a result, even if a large force is applied to the fixed portion of the ring member 24, such a large force can be appropriately released. This makes it possible to prevent problems such as the mounting angle of the main body 16 being misaligned relative to the bollard 13. [Third embodiment]

[0044] The outfitted mooring hook 11 of the third embodiment will be described with reference to Figures 8 and 9. The outfitted mooring hook 11 of this embodiment differs from the first embodiment in that the shape of the main body 16 is different from that of the first embodiment, and the hook member 22 is attached to the top surface 13C of the bollard 13.

[0045] The equipped mooring hook 11 comprises a main body 16 that is directly attached to the bollard 13 and has a receiving portion 15 that receives the mooring line 14, a claw member 17 that is rotatable relative to the main body 16 between a lock position P1 and a release position P2, an actuator 18 that rotates the claw member 17 as described above, and a controller 21 that operates the actuator 18.

[0046] The main body 16 comprises a hook member 22 that defines a receiving portion 15 on its inner surface (upper surface), a pair of auxiliary claws 23 that protrude above the receiving portion 15, a first part 24A and a second part 24B of a cylindrical ring member 24 fastened to the outer surface 13B of the bollard 13, a third part 24C of the disk-shaped ring member 24 attached to the top surface 13C of the bollard 13, a connecting portion 25 that is integrally formed with the third part 24C so as to stand upright on the upper surface of the third part 24C, and a pair of reinforcing ribs 52 that are welded and fixed to the top plate 55 of the connecting portion 25, the third part 24C, and the second part 24B of the ring member 24.

[0047] Each part of the main body 16 is made of cast steel. The ring member 24 has a first part 24A that is semicircular when viewed from above, a second part 24B that is also semicircular when viewed from above, and a third part 24C. The first part 24A is fixed integrally to the second part 24B with bolts and nuts 33. The ring member 24 is detachable from the bollard 13, and has a structure that makes it easy to restore it to its original state.

[0048] The connecting portion 25 is provided at a position corresponding to the top surface 13C of the bollard 13. The connecting portion 25 can support the hook member 22 so that it can rotate within a horizontal plane. Therefore, as shown in FIG. 9 , the rotation center (support) of the connecting portion 25 is located coaxially with the central axis of the bollard 13. That is, the connecting portion 25 has a support tube 53 welded to the upper surface of the third portion 24C, a cylindrical support 54 inserted inside the support tube 53, a top plate 55 supporting the upper end of the support 54, and an arm 56 integrally protruding from the support tube 53. The support 54 is inserted inside the support tube 53 so as to be rotatable relative to the support tube 53. The arm 56 is made of cast steel and is integrally formed with the support 54. Alternatively, the support 54 may be press-fitted into a through-hole provided in the arm 56 to be integrally formed with the arm 56. The arm 56 supports the hook member 22.

[0049] In this embodiment, the support cylinder portion 53 and the support pillar 54 correspond to the first joint portion 34 of the first embodiment. The arm portion 56 can support the hook member 22 so that it can swing left and right around the support pillar 54 within a range of, for example, 140 to 180 degrees in the horizontal plane. The configuration of the second joint portion 35 of the connecting portion 25 is the same as in the first embodiment.

[0050] The operation of the outfitted mooring hook 11 of this embodiment will be described. In the outfitted mooring hook 11 of this embodiment, the rotation center (support) of the connecting part 25 is located coaxially with the central axis of the bollard 13. Therefore, even if a large pulling force is generated in the horizontal plane on the hook member 22, a large moment of force is prevented from acting on the ring member 24 fixed to the bollard 13. The process of releasing the mooring line 14 and the process of re-mooring the mooring line 14 are the same as in the first embodiment.

[0051] According to this embodiment, the following can be said: The outfitted mooring hook 11 is attached to the top surface 13C of a cylindrical bollard 13 of a ship and comprises a main body 16 having a receiving portion 15 that receives a mooring line 14, a claw member 17 that is rotatable relative to the main body 16 between a locked position P1 in which the outlet of the receiving portion 15 is closed and a released position P2 in which the outlet of the receiving portion 15 is open, an actuator 18 that is provided on the main body 16 and that moves the claw member 17 from the locked position P1 to the released position P2, and a controller 21 that operates the actuator 18.

[0052] This configuration makes it possible to realize an outfitted mooring hook 11 that can semi-automatically release the mooring line 14 when leaving the ship's side or leaving shore. This allows the mooring line 14 to be released quickly in an emergency without imposing a burden on the worker or causing an unexpected accident.

[0053] The connecting portion 25 is provided at a position corresponding to the top surface 13C so that its rotation center is located coaxially with the central axis of the bollard 13. With this configuration, even if a large force acts on the hook member 22 from the mooring line 14, the moment of force acting on the ring member 24 fixed to the bollard 13 can be minimized. Therefore, even if a large force is applied during mooring due to the movement or rolling of the hull, problems such as slipping of the ring member 24 fixed to the bollard 13 and misalignment of the mounting angle of the ring member 24 are prevented as much as possible.

[0054] The above-described embodiments can be implemented with various substitutions and modifications. It is also possible to appropriately combine the above-described different embodiments to form a single invention. That is, in the first embodiment, the main body 16 is attached to the outer peripheral surface 13B of the bollard 13, and in the third embodiment, the main body 16 is attached to the top surface 13C of the bollard 13. However, it is also possible to attach the main body 16 so that it straddles both the outer peripheral surface 13B and the top surface 13C of the bollard 13. [Explanation of symbols]
