[Problems to be solved by the device]

 However, conventionally, no matter which of the fenders a, b, c, f is installed and used on the quay e, the height of each fender, that is, from the side surface of the quay e to the front surface (front surface) of each fender. Since the distance is constant, even if a large number of fenders are installed on the side surface of the quay e, as shown in FIG. 6, the contact area j with the hull i may be different depending on the shape of the outer shell of the hull i. Is the center of the hull, and the bow and stern cannot be in contact with the fenders apart from the quay e, and the number of fenders that come into contact with the ship is small. As a result, the hull i moves in the direction of the arrow due to the external force of the waves or wind, and positioning is difficult when loading cargo such as containers. Also, when the hull i moves under the external force of the waves or wind. However, there is a problem that an excessive external force is applied to the mooring line k, and the mooring line k 1 may be severely damaged or cut.

In view of the above, the present invention aims to enable the ship to be stabilized at the time of berthing or when it comes into contact with other ships or other objects, in accordance with the shape of the ship-side outer plate of the hull. Is.

[0006]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a fender body, which is a telescopic box-shaped body and is made of an elastic member whose surface is inclined according to the shape of the hull-side outer plate of the hull, and which has a hull-shaped outer portion of the hull. It has a size that allows it to come into contact with the plate, and is further equipped with a supply / discharge device for injecting fluid into the fender main body or discharging the internal fluid so that it can be fixed or moved to the hull or quay. Be prepared for.

[0007]

[Action]

 When a fluid such as air is injected into the interior to inflate it, it becomes a large fender that is elastic and expands and contracts.Therefore, if an appropriate number of hulls or quay were provided, the hull would be separated from the quay side surface in the past. Even when the hull does not hit the fender, the hull can be brought into contact with the fender, and the impact when the hull contacts can be mitigated. Moreover, since the surface of the fender is inclined according to the shape of the hull, it is possible to increase the contact area with the hull. This allows the hull to be moored in a stable condition.

The absorption force and reaction force of the fender can be adjusted by the amount of fluid to be injected.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 (a), (b), (c), and (d) show an example of a fender of the present invention, which is used for mooring a hull 2 by mooring it to a quay 1. The bow-side and stern-side shells of No. 2 are curved so that they can be applied to places away from the quay 1.

That is, in order to reduce the impact force of the hull 2 when the hull 2 is brought into contact with the side surface of the quay 1, the surface 3a uniformly contacts the outer shell of the hull 2 when expanded. As described above, the box-shaped hollow structure fender body 3 made of an elastic material (rubber or the like) whose surface is substantially trapezoidal is formed by inclining the surface 3a according to the shape of the ship-side outer plate. Further, a fluid supply pipe 4 for injecting and discharging air and other fluids into the inside of the fender body 3 is connected, and an opening / closing valve 5 is provided in the middle of the fluid supply pipe 4 and the opening / closing valve 5 is provided. 5 and the fender main body 3 are provided with an on-off valve 8 by connecting a fluid relief pipe 6 having a pressure gauge 7 on the way, and the fluid supply pipe 4, the on-off valve 5, the fluid relief pipe 6, the on-off valve. 8 constitutes a supply / discharge device, and opens and closes the on-off valve 5 described above. When the valve 8 is closed and a fluid such as air is supplied from the fluid supply pipe 4 into the fender body 3, the fender body 3 expands from the contracted state and the box is formed as shown in FIGS. 1 (a), (b) and (c). The fender I of the present invention is formed into a mold, and the open / close valve 5 is closed so that the fluid can be enclosed and it can be used as an air pillow.

When air or the like is injected into the fender main body 3 to inflate it, since the material is rubber or the like, in addition to elasticity due to the material itself, it has an absorbing force and a reaction force depending on the amount of fluid such as air inside. Can be made. The absorption force and the reaction force can be adjusted by adjusting the amount of fluid to be put into the fender main body 3 or by removing the fluid in the fender main body 3 from the fluid escape pipe 6.

The fender I of the present invention is used by being fixed or movable on a quay or the like.

FIG. 2 shows an example in which it is hung and used, and a hanging fitting 9 is provided on the upper surface of the fender body 3 so that it can be hung and supported by a hanging rope-like object 10 such as a chain or a wire rope. The installation position can be changed vertically depending on the place of use, and it can be freely displaced laterally according to the shape of the outer shell of the hull 2.

As another example, FIG. 3 shows a structure in which the rails can be moved laterally along the side surface of the quay 1. Two rails 11 and 12 are horizontally installed on the side surface of the quay 1 in parallel. A horizontal wheel 16 is mounted on the lower rail 12 so that it can roll on the lower rail 12 at the lower end side of a fender mount 15 that is supported on the upper rail 11 via a vertical wheel 13 and a horizontal wheel 14 so as to traverse. The fender mount 15 can be moved laterally along the quay 1 along 11 and 12, and the fender main body 3 is integrally attached to the fender mount 15 so that the fender main body 3 is installed along the rails 11 and 12. It is designed so that it can be moved.

According to FIG. 3, when various ships having different sizes of hulls are brought into berth, it can be dealt with by arbitrarily moving along the rails 11 and 12 on the side surface of the quay 1. It is possible to effectively berth various hulls of different ships.

Next, FIG. 4 shows, as still another example, a structure in which the fender main body 3 can be pulled up onto the quay 1. That is, a guide rail 17 that is continuous from the upper surface to the side surface of the quay 1 is installed, the fender main body 3 is fixed to a moving body 18 that can move along the guide rail 17, and the wire rope is moved up and down with a winch (not shown) or the like. Alternatively, the wheels 19 are driven so that they can be automatically moved up and down, and when not in use, they can be pulled up onto the upper surface of the quay 1 and stored.

Therefore, according to the example of FIG. 4, when the hull is brought into contact with the quay 1 for cargo handling work, the fender main body 3 is lowered along the guide rail 17 to a required height position on the side surface of the quay 1. . As a result, the fender of the present invention can be installed on the side of the quay and contact the hull.

In any of the installation methods shown in FIGS. 2 to 4 described above, since the surface 3a of the fender main body 3 conforms to the shape of the hull, a large contact area with the hull can be secured when the hull is docked. It becomes possible to moor the hull stably. Also, the impact force when the hull is berthed is alleviated by the absorption force and the reaction force generated because the material of the fender body 3 is rubber and the inside is filled with fluid such as air. be able to.

The above-mentioned installation methods have been shown so that the fender body 3 can be moved so that the type of ship to be docked can be accommodated even if the type of ship to be docked changes. If the size of the fender is fixed, the fender body 3 can be fixed to the side surface of the quay 1 in advance.

It should be noted that the present invention is not limited to the above embodiment, and for example, in the case where the fender body 3 is tilted on one side in the longitudinal direction and viewed in plan as shown in FIG. However, it is possible to increase the contact area with the hull by inclining it further in the vertical direction so that the outer shell of the hull 2 can be deformed in the vertical direction. Although it has been shown that it is used on the side of the quay 1 when making contact with the ship 1, it may be equipped on the side of the hull, and it can also be applied when making contact between ships, and other deviations from the gist of the present invention Of course, various changes can be made within the range not covered.

[0022]

[Effect of device]

 As described above, according to the fender of the present invention, the size of the hull is such that the tail of the hull can be contacted, and the surface side of the hull that contacts the hull is tilted according to the shape of the hull and has elasticity. It is designed to swell when a fluid such as air is introduced, the absorption force and the reaction force can be changed depending on the amount of the fluid injected, and the fixed type or the movable type can be used. It can exert an excellent effect. (i) Even when the hull is separated from the quay and does not contact the hull with the conventional fender, the hull can be contacted to receive the external force of the hull. (ii) Since the surface is inclined so as to match the shape of the hull, a large pressure receiving area can be taken, which can restrain the lateral movement of the hull caused by wind waves and facilitate the positioning of luggage on the ship. (iii) As described in (ii) above, the lateral movement of the hull is restrained, so that excessive external force is not applied to the mooring line, and there is no risk of cutting the mooring line. (iv) By making it possible to move horizontally or vertically along the quay via the fender mount, it is possible to cope with changes in the size and shape of the ship. (v) It can be made into a portable type by draining the internal fluid, and by loading it on a ship, it can be easily used when docking at the quay of each destination or in contact with another ship. (vi) The amount of absorbed energy and reaction force can be changed by adjusting the amount of fluid inside, and the large impact force of the hull can be alleviated.
